Kim, Ho Sung ; Jung, Dong Keun ;
The Journal of the Korea Contents Association, volume 13, issue 2, 2013, Pages 1~7
DOI : 10.5392/JKCA.2013.13.02.001
This study was aimed to evaluate the characteristics of impact sound of golf driver according to impact points of its face. In order to get the consistent impact sounds, the apparatus for free golf ball drop was prepared and used. Timed amplitude patterns and maximum spectral peaks of the impact sounds were variant according to the impact points of driver face. As an alternative method of impact sound analysis, cumulative sum of spectral power (cumsum) was used to distinguish between impact sounds according to the impact positions. From the comparison of frequencies representing 20%, 40%, 60%, 80% of cumsum of impact sound, 40% cumsum frequency of the center of driver face was lower than that of the toe and the heel. This finding suggests that the impact sound from the center of driver face has higher spectral power of low frequency component than that of the toe and heel.

Since the high readable source codes help us to understand and modify the program, it is much easy to maintain them. The readability of source code is not only affected by the complexity of algorithms such as control structures but also affected by the coding styles such as naming and indentation. Although various coding standards have been presented for promoting the readability of source codes, it has been usually lost or ignored in a programming course. One of the reasons is that the coding standard is not a hard-and-false rule since it does not contribute to the performance of software. In this paper, we propose a simple automatic system, namely StyleJigsaw, which checks the style of the source codes written by C/C++ or Java. In this system, the coding style score is calculated and visualized as a jigsaw puzzle. To measure the educational effectiveness of StyleJigsaw, several experiments have been conducted on a class students in C++ programming course. According to the experimental results, the coding style score increased about 8.0 points(10.9%) on average using StyleJigsaw. Further, according to a questionnaire survey targeting the students who attended the programming course, about 88.5% of the students responded that StyleJigsaw was of help to learn the coding standards. We expect that the StyleJigsaw can be effectively used to encourage the students to obey the coding standards, resulting in high readable programs.

These days, there are more and more IT research institutions which foresee cloud services as the predominant IT service in the near future and there, in fact, are actual cloud services provided by some IT leading vendors. Regardless of physical location of the service and environment of the system, cloud service can provide users with storage services, usage of data and software. On the other hand, cloud service has challenges as well. Even though cloud service has its edge in terms of the extent to which the IT resource can be freely utilized regardless of the confinement of hardware, the availability is another problem to be solved. Hence, this paper is dedicated to tackle the aforementioned issues; prerequisites of cloud computing for distributed file system, open source based Hadoop distributed file system, in-memory database technology and high availability database system. Also the author tries to body out the high availability mass distributed data management architecture in cloud service`s perspective using currently used distributed file system in cloud computing market.
Efficient Parallel IP Address Lookup Architecture with Smart Distributor
Kim, Junghwan ; Kim, Jinsoo ;
The Journal of the Korea Contents Association, volume 13, issue 2, 2013, Pages 44~51
DOI : 10.5392/JKCA.2013.13.02.044
Routers should perform fast IP address lookup for Internet to provide high-speed service. In this paper, we present a hybrid parallel IP address lookup structure composed of four-stage pipeline. It achieves parallelism at low cost by using multiple SRAMs in stage 2 and partitioned TCAMs in stage 3, and improves the performance through pipelining. The smart distributor in stage 1 does not transfer any IP address identical to previous one toward the next stage, but only uses the result of the previous lookup. So it improves throughput of lookup by caching effects, and decreases the access conflict to TCAM bank in stage 3 as well. In the last stage, the reorder buffer rearranges the completed IP addresses according to the input order. We evaluate the performance of our parallel pipelined IP lookup structure comparing with previous hybrid structure, using the real routing table and traffic distributions generated by Zipf`s law.

In wireless sensor networks, the geographical positioning scheme is one of core technologies for sensor applications such as disaster monitoring and environment monitoring. For this reason, studies on range-free positioning schemes have been actively progressing. The density probability scheme based on central limit theorem and normal distribution was proposed to improve the location accuracy in non-uniform sensor network environments. The density probability scheme measures the final positions of unknown nodes by estimating distance through the sensor node communication. However, it has a problem that all of the neighboring nodes have the same 1-hop distance. In this paper, we propose an efficient sensor positioning scheme that overcomes this problem. The proposed scheme performs the second positioning step through the sensing range control after estimating the 1-hop distance of each node in order to minimize the estimation error. Our experimental results show that our proposed scheme improves the accuracy of sensor positioning by about 9% over the density probability scheme and by about 48% over the DV-HOP scheme.

This study proposes smart-phone game applications success model based on mobile internet success model and investigates the effects of cultural propensities especially, uncertainty avoidance and power distance at the individual level. To achieve our research purposes, the study conducted survey in Korea and a total of 221 people participated in the survey. We classified user types by cultural difference as a moderating variable. User`s cultural propensity classified two groups: high uncertainty avoidance and high power distance, low uncertainty avoidance and low power distance. This study results reveal that the impact of quality factors on user satisfaction have difference according to cultural propensities.
Evaluation on Status of Independent PP (Program Provider)
Kim, Deaho ; Kim, In-Hee ;
The Journal of the Korea Contents Association, volume 13, issue 2, 2013, Pages 71~80
DOI : 10.5392/JKCA.2013.13.02.071
This study addressed status of PP(Program Provider) market, particularly focusing on independent PP. This research selected 14 independent channels and did in depth interviews for them. This study analyzed 14 channels in terms of management, production, and contents. The result showed that independent channels were in inferior condition than MPP(multiple PP) on all the aspects of management, production and content. The management structure of the PP were very vulnerable, production environment was not good. The PP were placed in a difficult environment in terms of production and purchases of content, therefore focused on distribution rather than production. This unbalance on the PP market resulted in negative effect on Korea`s contents industry as well as PP industry. Therefore, this study suggested policy and regulatory reforms are needed to improve inferior status of independent PP.

Hong, Kyung-Soo ;
The Journal of the Korea Contents Association, volume 13, issue 2, 2013, Pages 81~87
DOI : 10.5392/JKCA.2013.13.02.081
SBS [Healing Camp] seems like having a different sound usage from other entertainment programs. After content analysis, I found that [Healing Camp] uses much more music & sound effects than [Muhandojeon]. Music & sound effects of [Healing Camp] has functions of tautological informing, uplush of emotion or Ancrage, narrating or Relais. It is very similar to television subtitle. Positive uses of music & sound effects are expected to catch the attention of audience and to increase the ratings. But [Healing Camp] uses music & sound effects very positively and systematically and opens a new dimension of narratives.

The Journal of the Korea Contents Association, volume 13, issue 2, 2013, Pages 88~99
DOI : 10.5392/JKCA.2013.13.02.088
This study considered the transition of changes in social status of the film through the discourse analysis of printed media, having been published since 6th revised film policy in 1987. For the purpose, Pierre Bourdieu`s cultural sociology, or `Field theory approach` was engaged as a theoretical background. On the basis of that theory, changes in social status was divided into expert and popular field. From 1988 to 2007, doctor`s and master`s theses on filmologie and the representative academic journal, "Film Studies" were examined with regard to area of expertise, and movie-related books with regard to popular one. This study demonstrated that the symbolic capital had inhered in the cinematic field along with specialization and diversification of analytic aspects, and the relation between the academic approach and political consideration had performed an important role in intellectualization of film.
Agnès Varda`s Vagabond and Aesthetic
Kim, Sook-Hyun ;
The Journal of the Korea Contents Association, volume 13, issue 2, 2013, Pages 100~107

s Varda is a French representative female film director. In particular, the method combining subjectivity and objectivity is the most outstanding characteristics. However, it can be said that the method to support this is not only theme of the film but also creation of structure including the exploration for the filmic form different from classical film form. Such an approach accords with No
l Burch`s refined analysis of filmic form. Therefore, This study aims to aesthetical analysis of the form of producing the structure in modern movies through
which is one of the representative work by Agn
sVarda and won the Golden Lion award in 1985 Venice Film Festival. The theme of the film, the recovery of relationships among people and contacts through the tragic death of drifting life, created a new filmic structure by formative experiment of the film. The formative experiment is the fragmented and repetitive construction with the introductory voice-over, and consists of movement and editing of camera and specific use of flashback and sound through the representation of figures and situations, mixture of narrative and non-narrative style.

The Journal of the Korea Contents Association, volume 13, issue 2, 2013, Pages 108~126
DOI : 10.5392/JKCA.2013.13.02.108
The purpose of this study is to develop the basic scales of festival quality. We conducted a content analysis in the discourse of KINDS(Korea Integrated News Database System) and derived five constituent factors, basic quality measures of local festivals through the extensive literature review. We named these qualities "Festival BASICQUAL" that is consist of Infrastructure, Connectedness, Passion, Theme, Culture. We conducted the empirical analysis for the participants in "Geumsan Insam Festival" to verify the "Festival BASICQUAL" As the result, Infrastructure, Connectedness, Culture affected positively on Festival Attachment among all BASICQUALs. However, Passion and Theme did not positively affected on the dependent variable. And then, Festival Attachment positively affected on Festival Satisfaction, while Festival Satisfaction also affected positively on Behavior Intention. This study developed the basic quality concerned with local festivals which is crucial fundamentals to quantify Festival BASICQUAL through empirical study. The proper applications and usage of these newly introduced local festival qualities enable to acquire the sustainable competitive advantage in local festival.

The vague anxiety or disbelief about new media undermines the confidence of old media about controlling the future. The negative response of old media makes the vicious circle. In spite of the development of new media and IT industry, the conservative view regards computer game as taboo. The absolute taboo provokes the absolute fear. Then the absolute taboo is `computer game` in today`s Korean society. Computer game as play in the digital era is burdened by the critique on the non-productivity and the deviation. And what`s more, the digital technology of computer game intensifies the image of `virtuality`. It cause the fear about computer game. This article starts on the understanding about computer game and inspects the mass image about computer game which is caused by the various aspects of cultural or technological facts in computer game. From this inspection, the article explains the mechanism of gamephobia and suggests the view to catch the cultural value of computer game beyond the fear.

Kim, Jong-Sun ;
The Journal of the Korea Contents Association, volume 13, issue 2, 2013, Pages 188~197
DOI : 10.5392/JKCA.2013.13.02.188
The purpose of the study is to develop an index for basic management diagnosis of domestic industrial crafts companies. After the verification processes aimed at experts working in industrial crafts companies, the index of basic management diagnosis that has been researched and developed so far was turned out to be inappropriate to investigate the management of industrial crafts companies, in which the organized management system is not equipped due to their small-scale business environment. It is because the current index of management diagnosis was designed for diagnosis from the functional perspective. Therefore, in this study, the new index of management diagnosis was developed in order to diagnose the management of industrial crafts companies from the process perspective. This index is divided into three elements of Plan, Do, and See, which represents the management process cycle with focus on activities of industrial crafts companies. In addition, through literature study and Focus Group Interview (FGI) based on this index, detailed aspects and items of diagnosis, and checklists were emerged. This index of management is designed for the basic management diagnosis of industrial crafts, and it is possible to figure out management problems from diverse perspectives. For further research, the effectiveness of the index of management should be verified through diagnosing the management of industrial crafts companies and grasping management problems from varied perspectives.

This study investigates the detrimental effect of watching sexual content in three-dimensional (3D) moving pictures. An increasing amount of investment is put especially in 3D adult content to boost their 3D media industries. It is crucial that the effect of sexual contents on viewers be identified. In this experiment, a between-subject design was employed to analyze various effect of sexual content on participants whether they viewed the same stimuli in 3D or in 2D. In particular, the presence scaling was used to evaluate how real the video clip is. In addition, the permissiveness toward sexual behaviors and the level of sexual arousal were measured to examine the different effect of sexual content by dividing two separate groups in 2D and 3D condition. The result shows that those who watched a 3D video clip perceived higher sense of presence compared to those who watched a 2D video clip. Furthermore, subjects in 3D condition reported lower scores of permissive attitude toward sexual behaviors. This confirms that 3D display delivers more visual experience and has an impact on people in terms of perceiving sexual contents and changing their attitudes towards sexual behaviors.

This study analyzes the interaction of variables consisting of the local finance system based on the theory of system thinking regarding how financial decentralization can be understood as the political means for local decentralization and why it is needed. The results gained from this research are as follows: first, variables consisting of the local finance system form interactional relationship in the significant level, and it has been found that rapid growth and rapid decline repeat with five positive feedback loops as the center. Second, strategic points for the validity of local finance decentralization were discovered through causal map modeling. In particular, it has been shown that the virtuous cycle structure declines the local finance system through the constant operation of variables (government subsidies, taxation for real estate transactions, central government`s local finance mediation system, and local government debt, etc.) that deteriorate the vicious cycle structure. Based on this, strategic policy tasks were drawn. It is expected that this study will help the understanding of the local finance system and increase academic width for local finance from the aspects of general knowledge, not the knowledge about local finance decentralization.

In this paper, we measured specific absorption rate (SAR) using characteristic variables such as flip angle, repetition time (TR) and echo time (TE) at magnetic resonance imaging. The subject was applied to same scan technique from body weight 10 kg to 90 kg, were measured for the average SAR and the peak SAR values according to the change of parameter. SAR with different body weight levels was not seen a significant change at TE but it increased in the larger flip angle and the shorter TR. SAR value was within the limits of human head acceptable standard and SNR in segmental body weights was not proportional to the increase of body weights. In conclusion, this study can be helpful for diagnosis by using appropriate parameters which obtained the various contrast and SNR.

Photodynamic therapy(PDT) has been recommended as an alternative therapy for various diseases including microbial infection. The aim of the present study is to evaluate the antimicrobial effect of PDT using a photofrin and home made 630 nm Light emitting diode(LED) against Staphylococci. To examine the antimicrobial effect of photofrin-mediated PDT against Staphylococcus aureus and Staphylococcus epidermidis colony forming units(CFU) quantification, and bacterial viability using flow cytometry were formed. The CFU quantification results of S. aureus and S. epidermidis were 1 cfu/ml and 16 cfu/ml of average, respectively, after PDT application with photofrin of
and 630 nm LED and energy density of
. In addition, S. aureus and S. epidermidis isolates yielded forward-scatter (FSC) and fluorescence intensity (FI) differences on flow cytometry (FCM) after PDT. S. aureus and S. epidermidis cell size(FSC) increased 8.96% and 5.55% respectively, after PDT. Also the numbers of dead cell of S. aureus and S. epidermidis were a 39% and 61% incerased. These results suggest that photofrin-mediated PDT can be an effective alternative treatment for antibacterial therapy.

Recently there is a heated debate going on regarding the patient-doctor communication in the medical schools and medical service sector. Patient-doctor communication is an interactive communication made during the consultation session which is known to bring positive effect to both the patient and the doctor. Through this research, a doctor coaching model was developed by combining a method that would help the patient and doctor communicate better by increasing the doctor`s communication skill and a coaching mechanism. Through the research, the doctor coaching model consists of 5 levels. First is the `relationship creation` which would cause the doctor`s interest and expectations toward coaching mechanism. Second is `recognition of change` and this would cause to understand the problem and pros of the doctor`s communication with the patient and set a direction regarding the coaching. Third is `understanding the perspective` and this would lead the doctor to think from the patient`s perspective. Fourth is `increasing problem solving and communication skills` and this would set specific terms as to how the doctor can improve his communication skills. Fifth is `goal setting and support` where goal regarding the improvements can be set and agreement regarding the ways to maintain and strengthen the advantage can be made. The developed doctor coaching model is most meaningful in a way that it has first adapted a coaching mechanism to improve patient-doctor communication. Also in cases where such will be utilized in the future medical service sector, it is expected to affect greatly the doctor`s communication skill and patient sympathizing skills. Hereby it will contribute in increasing the patient`s treatment satisfaction.

This study aimed to investigate the effect of a lap board that was developed to prevent musculoskeletal disorders caused by the use of a computer mouse. Study participants were 10 college students in their 20s who did not have any musculoskeletal symptoms. We analyzed the difference in upper limb movements, electromyographic activity, task performance, and subjective discomfort between 2 conditions: use of a mouse with the lap board and use of a mouse placed on a desk. Results of behavior analysis showed that there was a significant difference between the 2 conditions in terms of the average angle of shoulder flexion, shoulder internal rotation, and forearm pronation(p< 0.05). However, electromyographic activity, task performance, and subjective discomfort showed no significant differences between the 2 conditions. When subjects used the mouse with the lap board, their upper extremity was located much closer to the torso than when they used the mouse placed on the desk. Six of 10 participating students preferred the lap board. We expect that advanced research on prevention of musculoskeletal disorders due to the use of the computer mouse will be conducted in the near future.

In this study, the relationship between social support and adolescent mental health was examined. A primary aim was to investigate how family, school, and friends affect adolescent mental health including depression, stress, and anger issues. This study also intended to investigate the indirect effect of these factors through the mediator, problem drinking. The study used survey data collected from the "2010 The Study on Mental Health of Korean Adolescents" conducted by National Youth Policy Institute, and 942 subjects were selected for this study. The study hypotheses were tested using SEM (Structural Equation Modeling) analysis. Analyses revealed that the appropriate functions and roles of the family members had the effect of promoting mental health of adolescents. Inappropriate functions and roles of the family members induced problem drinking, and this eventually had a negative impact on mental health causing depression, stress, and angel problems. Results also showed that having more friends who drink alcohol or smoke cigarette had no direct effect on the mental health of adolescents; however, there was an indirect effect through the mediator variable, problem drinking. The finding of this study revealed the need and importance of appropriate social support system and environment in order to promote mental health of adolescents.

Health care expenditure might be understood as a core source of social welfare. It is mainly due to the fact that the health care expenditure is closely related to the level of social welfare. And, therefore, the paper is basically designed to investigate the effect of social welfare improvement resulted from an increasing in per capita, private, public, and total health care expenditures during 1995-2009 periods. Empirical evidence reveals that the improvement of social welfare in middle income group reveals the highest improvement in social welfare, and the other income groups maintain a quite similar pattern in improvement of social welfare. As far as category of health care expenditure concerns, the effect of social welfare improvement by per capita health care expenditure is in general lower in all case. And, private sector achieves the highest improvement of social welfare in comparing with public and total health care expenditures. To this end, it could be tentatively concluded that the private health care expenditure has to be substituted for the public sector to induce market-oriented operational system. Accordingly, it would be better to build an institutional basis more elaborately in setting up the market system.

The purpose of this study is to examine the impact of enterprise R&D investment on inter-industry technology spillover in Korea under the new Normal Era. In order to do this, we tested the effect of production inducement, backward and forward linkage effects, and the effect of technology spillover such as technology intensity effects and technology diffusion effects based on an input-output framework. The results show that the high index industries of the production inducement effect were professional, scientific and technical activities, manufacture of metal products, and general machinery. Some manufacturers of other non-metallic mineral products and transport equipment sectors appeared to have the strong effect of forward and backward linkages that were almost equivalent to high-tech manufacturing industries. In particular, the industries of professional, scientific and technical activities appeared to have the strong effect of both forward and backward linkages. Therefore, we need to drive a strong policy support to higher enterprise R&D investment in the those particular industries not only to increase global competitiveness, but also to widen up the technology spillover effect on other industries.

OCB(organizational citizenship behavior) is a employee behavior that goes above and beyond the call of duty, that is discretionary and not explicitly recognized by the employing organization`s formal reward system, and that contributes to organizational effectiveness. In a word, OCB has great potential as a organizational slack. As such, researchers have been showing great interest in the antecedents of OCB, and as a result, now we can meet so many antecedents of OCB from individual level variables to group or organizational level variables that are said to be important in explaining OCB. Additionally each of these variables is known to have its own sound logic and statistically significant effect on OCB. However the results of these studies are so fragmented that researchers have a great difficulty in drawing some meaningful or coherent conclusions. In this context, we try to applicate Q-methodology to find more coherent way of explaining the motives of OCB, and briefly speaking, we find four types of the motives of OCB, that is norm-based, instrumentality-based, trait-based, and avoidance-based type. Among these the last avoidance-based type is especially interesting, because we can`t find any remarks on this type in the previous studies. The paper ends with suggestions for future research directions. We expect that these suggestions could be a foundation on which more developed and coherent OCB theories stand. We don`t see this approach supplanting earlier efforts; rather we believe this can offer more detailed explanation in addition to those provided by other approaches.

Firm`s competitive advantage and profitability can be gained over competitors by human resources and human resource management that are characterized by idiosyncrasies or differentiation. Yet, the results of previous studies have been a emerging consensus that the isomorphism and homogeneity of HRM and HR practices among firms regardless of thoese industrial areas, size, organizational settings, etc. are universal. Based on the previous studies of similarities of HRM, the paper theoretically investigates the background and reasons of introducing similar HR practices among firms. The paper shows the dynamism of HR system in Korean firms, adapting a new HR system. Three types of reasons are found, coercive isomorphism, mimetic isomorphism, and normative isomorphism. However, it is also discussed that there is an important gap in the theoretical and empirical research. More empirical research is suggested in order for gaining meaningful results on HR studies.

In this study, we investigate the current status of family friendly management and determinants of its level. We choose measures about family friendly management and use their results from ESG evaluation model by Korea Corporate Governance Service. We find that firms with larger size, lower leverage and higher firm value are more family friendly. And in contrast to previous studies, firms are more family friendly when they have less women to total employees. But firms with higher largest shareholder holdings are less family friendly. These results show that listed firms in Korea should be more family friendly considering their level of woman employment. Also the interest and support from top management are needed for activating family friendly management, but largest shareholder of korean firms are not active yet.

The purpose of this study is to analyze the apartment investment performance including the risk and to verify the presence or absence of regional characteristics. This study made an analysis on the apartment investment performance by dividing it into long and short-term basis. Data collection period is 10 years from 2002 to 2012 and target area includes Gangnam and Gangbuk (southern and northern area of Seoul) and 6 metropolitan cities. For evaluating the investment performance, this study used the earning rate of 5 year 1st class national housing bond as the risk-free rate of return and 1~2 year interest rate of fixed deposit for calculating lease profit. The results of study are as follows, Treynor`s Index was used in long investment performance evaluation because of regional characters non-existing in Seoul and Incheon whereas Jensen`s Index was used in evaluating because of regional characters existing in 5 metropolitan cities. And Jensen`s Index was used in short-term evaluation of all districts as existing regional characters in all districts. Short-term performance considering regional characteristics yielded different results of simple evaluation. Therefore, in case of simple rate of return to evaluate the performance, the recognition of that can be distorted.

DOI : 10.5392/JKCA.2013.13.02.440
This purpose of this paper is to study the economic effects of port-liquid freight by focusing on Korea port and induce its policy implication. For this, 29 sectors` input-output tables with port-logistic sector as an individual sector is constructed. The direct industrial effects of port-liquid freight are analysed to be an increase in about 3.6billion dollars` worth of production of the port-logistic industry, an increase in about 1.98billion dollars` worth of value-added of the industry, and the creation of about 11,589 employment in the industry. Including the indirect effects, the total effects on Korea economy are estimated to be an increase in about 4.9 billion dollar`s worth of production, an increase in about 2.4 billion dollars` worth of value-added and an increase in about 17,746 employment. The total effects of port-liquid freight on Korea economy is about 2.5-3.0% of that of port-logistic total freight. the results suggest tkat thought economic effects of port-liquid freightare not large, we have to focus on policy support for port of port-liquid freight.

This research is to verify the effects of Korean wave image on the national image and purchase intention of Korean educational product empirically. Also, it is to find out the moderating effect of engagement when Korean wave image is affecting purchase intention of Korean educational product. In order to verify this, the questionnaires were distributed to the Chinese university students of Shandong, in China, who recognized the Korean wave, and among those questionnaires, 315 were analyzed for this research. As a result of analysis, cognitive images is found out to make a positive effects on the affective image, national image and purchase intention of Korean educational products. And affective images is found out to make a positive effects on the national image and purchase intention of Korean educational products. This result suggests that throughout the factor of Korean wave, we should improve national image and try to find ways to export Korean educational industry to China. In order to activate Korean wave image in China, the government has to review the cultural contents development policies positively like promoting Korean soap operas.

DOI : 10.5392/JKCA.2013.13.02.475
The aim of this study is to examine an existence of mutual interdependency in terms of military expenditure and arms imports between Northeast Asian countries such as South Korea, North Korea, China, Japan, and U.S. Recently, the mood of post cold war and intensified globalization lead to be disarmament in pursuing a policy on national defence in many countries. Since potential menace to national security has been receiving more concern rather than a direct armed clash, mutual interdependency on military spending should be fully understood. For a methodological tools,
-convergences, convergence with rational expectation, and Granger causality test are employed. Empirical evidence shows that the convergences which are evaluated by
, and by a model based on rational expectation are in general revealed, and differences are more sensitive to a military decision making procedures. Granger causality, however, is not being existed. To this end, it would be concluded that the Northeast Asian countries are going with a trend in the world than forming their own tendency in this region.

Recently, the frequency of typhoons have increased due to the effects of climate change. As a result, in mountain streams, it has caused streamflow increase upstream and frequent water surface elevation downstream. This study analyzed the effects of the heavy rainfalls caused by Typhoon Sanba, which had a direct impact on Korea between September 17 and 18, on the water level variations downstream in mountainous streams. In addition, the drainage basin of Samcheok Oship stream was chosen as the object of this study. This study analyzed the flood level by applying HEC-RAS model. The observed water level measured in 2012 and the water level simulated by HEC-RAS model showed similar results. In addition, the simulation results showed the maximum flood level was 5.32m the mean flow velocity was 2.33m/sec and the maximum channel water depth was 7.51m. The analysis showed that the heavy rainfalls caused by Typhoon Sanba had an impact on the water surface elevation in Oship stream. The final results from this study will give a reasonable and important data to perform the Design of Hydraulic Structure.

DOI : 10.5392/JKCA.2013.13.02.505
A new boundary treatment technique which can be applied to axi-symmetric topography with inclined bottom was developed. Although the finite element method is good for complex geometry, there is no proper boundary treatment when a boundary is not a vertical section because the water depth at the coastline becomes zero. In this study, we developed a new boundary treatment for inclined bottom using the analytical solution for long wave. To develope a model, the mild-slope equation was used and then, a computational domain is divided into an analytical region and a numerical region. By combining a numerical and an analytical solutions, a complete solution was obtained. The developed solution was validated by comparing with a previous analytical solution.

This paper presents the user needs analysis and information visualization for the development of a semantic-based national R&D information navigation service in information service planning phase, which converges and fuses NDSL databases and NTIS databases. To investigate and analyze the user needs for improving usability, we make an improvement plan for R&D information services via a survey targeted at 30 persons, and on-site interviews targeted at 12 persons, almost of who are researchers in industries, universities and government-funded institutes. To design new information visualization service, we propose an interactive national R&D information visualization service, which is provided in navigation type, and prescribe persona and screen prototyping according to the user needs analysis. We design the national R&D information convergence/fusion architecture based on the NDSL databases, including 345,411 academic articles, 620,555 co-authors and 49,958 reports and NTIS databases including 187,466 national R&D projects. We expect that the national R&D information convergence/fusion architecture contributes to R&D information convergence/fusion as a leading model/standard and the interactive navigation-typed information visualization service strengthens usability continuously.
