Real Time Textile Animation Using Fuzzy Inference
Hwang, Seon-Min ; Song, Bok-Hee ; Yun, Han-Kyung ;
The Journal of the Korea Contents Association, volume 11, issue 9, 2011, Pages 1~8
DOI : 10.5392/JKCA.2011.11.9.001
A fuzzy inference technique for real-time textile animation without integration at textile model based Mass-Spring model is introduced. Until now many techniques have used the Mass-Spring model to describe elastically deformable objects like textile. A textile object is able to represent as a deformable surface composed of spring and masses, the movement of textile surface which is analysed through the numerical integration by the fundamental law of dynamics such as Hooke's law. However, the integration methods have 'instability problems' if the explicit Euler's method is applied or 'large amounts of calculation' if the implicit Euler's method is applied. A simple and fast animation technique for Mass-Spring model of a textile with fuzzy inference is proposed. The stabilized simulation result is obtained the state of each mass-point in real-time for the n of mass-points by a relatively simple calculation.

The wireless mesh networks are recently getting much attention for commercial applications. In such networks, the service should be uninterrupted when roaming from one domain to another while the authentication for a secure access should be maintained. The challenge is to consider the authentic coordination between the home domain and foreign domains and the maintenance of local authenticity between foreign domains. In this paper, a novel authentication method is presented so that a mobile mesh node can be effectively authenticated and obtain an secure connection in foreign domains. In the proposed method, the authentication process does not rely on an end-to-end connection between the foreign domain and the home domain. Even without a connectivity to the home domain, the foreign domain can provide an effective authentication of a mesh node by consulting one of the neighboring foreign domains that has been visited by the mobile mesh node. In order to verify the performance of our proposed method, a qualitative analysis has been performed and compared to those of conventional methods. The results show that our method is superior to the conventional ones in terms of authentication response time and authentication service robustness.

The Journal of the Korea Contents Association, volume 11, issue 9, 2011, Pages 26~44
DOI : 10.5392/JKCA.2011.11.9.026
The Study was carreid out to see whether the intensity of electromagnetic waves in each floor of a building where the sharing base station has been established is harmful to a human body, and to expect the intensity of the waves in the building. The investigate was performed on both of sharing base station either with many scatterers or without any of them. To satisfy the international standard and the domestic TTA standard, rms for each of the electromagnetic wave of every floor in the building with the station was measured from 3 location of 3 heights(1.1m,1.5m, and 1.7m). Max of the measured rsm from the each of the frequencies in the nine location was confirmed to be 48.12%(the rooftop measured value) at most, compared to the human body protection standard. The value was confirmed to satisfy the human body protection standard for each frequency. And the total value of the calculated exposure indexes for each frequency was determined to be more than 7 times lower at most, which was 0.1445, compared to the 1 standard. Since P value in both of 868MHz and 2.14GHz electromagnetic waves intensity for each base station and floor was less than 0.05, it was revealed to be meaningful, and since R-Sq(adj) value showed a value more than 50%, the regression equation was determined to fully absorb the data information. However, although the P value of both of 868MHz and 2.14GHz electromagnetic waves intensities under the integrating terms of the base station data and the floor data was showed to be less than 0,05, since R-Sq(adj) value of 868MHz electromagnetic waves intensity presented a value smaller than 50%(34.15%), it was determined that the 868MHz electromagnetic waves intensity is very much influenced by an environment with a base station. Because the electromagnetic waves intensity of 2.14GHz show R-Sq(adj) value bigger then 50%(51.8%), The regression equation model of 2.14GHz electromagnetic waves intensity was confirmed to be proper. It also turned out not to be effected by the surrounding environment near a building with the base station and the intensity of electromagnetic waves for each floor of such building was expectable by the regression equation.

According to the necessity of measuring equipments for advanced military systems, real-time characteristics such as time determinism and execution accuracy pursuing low-latencies have become very important. With this reason, the market demand for real-time features in the general purpose operating system such as Linux has been enlarging. To meet these requirements, RTLinux and RTAI has been developed as dual-kernels based on Linux. However, developers should use assembler languages to facilitate real-time in RT-Linux, it is very difficult to deal with it. RTAI has disadvantage that it only provides soft real-time. To solve these problems, RTiK-Linux was developed. In this paper, we propose a new dual-kernel with hard real-time capabilities in Linux, called RTiK-Linux(Real-Time implemented Kernel for Linux). We first introduce related researches and then describe the design methodologies to guarantee the resolution which almost accords with the timer settings. Finally, we present the results of experimental measurements and analyze them in order to validate and evaluate the proposed RTiK-Linux.

This paper proposes both global and local mobility management (MM) scheme improved from Multi Protocol Label Switching (MPLS)-based Mobility Management scheme (MPLS-MOB) for seamless service in Next Generation Network (NGN). The proposed scheme adds local MM on the existing MPLS-MOB which supports global MM by processing handover signaling by 2.5 layer switching via Label Switch Path (LSP) of MPLS. We numerically analyze and verify that the proposed scheme has lower handover latency time than the existing ones, such as micro-MM methods using MPLS as well as MIP and an interworking scenario between PMIP and MIP.
Abstraction Method for Analysis of Mobility and Interaction in Process Algebra Using Behavioral Ontology
Woo, Su-Jeong ; On, Jin-Ho ; Lee, Moon-Kun ;
The Journal of the Korea Contents Association, volume 11, issue 9, 2011, Pages 63~75
DOI : 10.5392/JKCA.2011.11.9.063
A number of process algebras have been proposed to develop distributed mobile real-time systems: pi-Calculus, Mobile Ambients Calculus, Bigraph, etc. However, as the systems get large and complex, the algebras become less suitable for understanding the interactions and mobility of the processes of the systems due to the size and complexity. Therefore it is necessary to handle the size and complexity for systematic understanding of the systems. This paper handles the size and complexity with a method of abstraction on sequences of interactions and movements of processes in the systems, which can be further organized in the form of hierarchically structured lattices, namely, Prism. The theoretical principle of the abstraction is based on a new concept of Behavior Ontology, which is extended from Active ontology. Prism allows the systems to be analyzed in the perspective of the lattices in Prism, which are characterized by the hierarchically organized behavioral properties of the developing systems, for systematic understanding the systems. In this way, the complexity of the interactions and the movements can be handled systematically in the semantically and hierarchically organized structure of the behavior.

Recently, sudden interests of mobile cloud computing as well as conventional internet environment are rapidly increased as cloud computing spread out in our web society. Mobile devices including smart phone are rapidly changing in a wholesale way that covers hardwares, applications, and services. However, the Internet access using mobile device is not quite smooth in this local mobile internet environment which suffers from lack of understanding and observance of Web Standards. Although most of domestic web sites are developed focusing on various functions and eye-catching designs, this should became one of the main factors that make the usability and accessability decrease when accessing web with smart phones or table PCs. Therefore, this paper suggested a web interface that considered usability and accessability under mobile cloud environment and we tried to prove it via usability test. It could be found that there was an improvement of usability of interface of the main page that has been optimized to the mobile device environment suggested from the previous research we present, but this paper aimed to prove a usability improvement of total website as a whole by performing the usability test on the entire website. Selecting a special website optimized for mobile cloud computing, we prove an improvement of usability and accessibility. Therefore, we offer a guideline about user interface design applications to developers or companies who want to construct mobile website.

The function of music in a motion picture ranges widely from supporting the storyline to being the main storyline delivering the major plots. This trend and can be seen in recently produced films, advertising as well as in music videos. Many attempts were made to express music visually in the past. But it was through Disney's creative production, "Fantasia", that such attempts became a reality in a motion picture. This paper will look into the difference between the "Fantasia" and "Fantasia 2000" through a comparative analysis of the correlation between the musical element and the storyline of the 2 Disney animation movies. The most distinct difference is that the "Fantasia" has a storyline that is faithful to the original interpretation of the true meaning of the music, while, on the other hand, the "Fantasia 2000" has a storyline that endeavors to express the special features of the overall sound of individual pieces as best as possible. And the differences between the two animations, thus compiled, is hoped to facilitate and enhance a better understanding of the two Disney's finest animations.

In this paper, the shielding material for the product design of various electrical appliances is suggested by more environmentally materials like as the lacquer and the charcoal. The suggested shielding material has the shielding effectiveness of 97.2%, 98.7%, and 96.3% at 900 MHz, 1.8 GHz, and 2.45 GHz, respectively. In the microwave oven and the cell phone, the metal or metal-coated plastic are used for the shielding of strong electromagnetic wave. However, by using more environmentally materials like as the lacquer and the charcoal, the products can be manufactured more light weighting, more heat-resisting, more abrasion resisting, and more corrosion resisting. Also, the products design can be varied more mellow and more friendly.

Citizens of 21st century which is called to be the era of 'Culture' express their cultural desires in their public environments. Governments found that these needs can be satisfied through the culture-centered public designs which are based on the local resources and identities. This research suggests the strategy programming model to support these projects. It aims at not suggesting the conceptual process model, but developing the practical supporting model with options to choose. Thus the indices which are related to each prototype phases of programming process are analyzed through the case analyses with qualitative approach. This paper focused on analyzing the indices for Place Strategy which includes the phases for Resource, Mission, and Targeting. Altogether, 81 indices are analyzed.

Considering the online idea generation, or web-storming, system would be used differently by space designers depending on their job characteristics, the present study tested the usability of web-storming using a factor correlation table with a designer group in the field. Then, for analyses, the results were compared with the previous findings on the usability of web-storming in a design administrator group to suggest comprehensive measures applicable to web-storming. The questionnaire results were analysed following a process of observation-interpretation-application, and the space design process and web-storming function factors were also analysed based on a factor correlation table. The analyses found that the most correlated space design process in both administrator and designer groups was the schematic design phase, and that the correlation started to lower upon division of labour. The assessment phase was found significantly different between the designer group and the administrator group. The assessment phase showed the second highest correlation in the designer group. In terms of the aspects related to project operation, the correlation was found higher in the designer group. Based on the findings, new applicable measures to each phase of web-storming were derived and summed up to suggest how to take advantage of web-storming in the field.

Asia has shown a tendency that a certain country's culture leads the fashion in turn every 10 years. The trend of Hong Kong movies in 1980's was called 'Hong Kong Wave', the trend of Japanese animation and games in 1990's was called 'Japanese Wave', and then the 'Korean Wave' began in the late 1990's. This term '~Wave(流)' is a Japanese-style term meaning '~way', '~style', '~group', and so on. In the same manner, recent popularity of Taiwanese TV dramas and a particular star that is in fashion in Japan are called 'Taiwanese Wave', and Chinese movies, broadcast, tourism, and etc. are called 'Chinese Wave'. Thus, the term 'Korean Wave' is a part of expression '~wave' used in Japan and it started to be used in the mean time, and was officially used in <韓流-Song from Korea>, a promotion record of Korean pop music, produced by Ministry of Culture and Tourism in Korea. In this paper I propose to correct the error of the term 'Korean Wave', and furthermore, to define a term expressing Korean culture and study for its usage.

This research addresses global status of Korean media firms and their future directions. Mapping of major international media firms all over the world is used in order to explain global status fully. In the four categories that classified media firms using Forbes Global 2000 mapping, all Korean media firms are included in the fourth group, which is the weakest in terms of global competitiveness. Therefore, it is essential to trace appropriate global strategy from the media industry value chain that has competence. This paper finds out that Korea has advantage in the contents, terminal, and next generation networks. That means alliance strategies of contents-terminal-next generation network have advantage to evolve into global media firms. Moreover, Korean media companies should adopt selection and concentration strategy in terms of geographical expansion. As Korea's broadcasting and game contents are already popular in Asian and Latin American regions, they would better to enter the emerging markets. In so doing, terrestrial broadcasters and game service providers should lead the way.

Users in the Web 2.0 era, which is based on the convergence of wired and wireless technologies, tend to have a high regard for digital contents interactions, as compared to the technology experienced at the analog era. To boost the digital contents business, it is necessary to focus on the digital contents(DC) interactions based on user-centered thinking to satisfy user preferences. According to previous studies, this study classified DC interactions into three types: interaction between users, interactions between contents and users, and interactions between system and users. This study empirically verifies that DC interactions factors affect flow as well as DC flow influences the DC use intention.

Several problems occurred due to the use of the wrong water cycle system in the watershed. This was caused by a dry stream in the lower parts of the tributaries and the deterioration in value of usage by water pollution in accordance with water storage. This was maintained for a long period of time in the reservoir which secured the agricultural water. As a result of the operational status in the agricultural reservoirs focused on Chungcheongnam-do and Daejeon metropolitan city, a dry stream appeared because hydraulic retention time(HRT) in the majority of reservoirs was maintained for 8 months of the year. The water quality in the agricultural reservoir was fairly related to the water cycle system due to rainfall and input of pollutants from the population and livestock in the watershed. Consequently, the storage water volume and the time period of the water in the reservoir should be controlled by the reduction of the pollution load in the water and the prevention of a dry stream. Also, the water cycle system in the watershed should be improved by maintaining a short HRT of the reservoir.

We often find that we, as a social group, share stereotypes of criminals. For the present study we investigated the stereotypes of rapists, and examined if they match their characteristics on the national crime statistics in Korea. Collecting data from 82 college students and 91 police officers, we compared stereotypes about rapists with the characteristics of those reported on the national crime statistics. As a result, we found that both college students and police officers have distorted stereotypes of rapists which are not consistent with their characteristics. More specifically, both college students and police officers believed that rapists came from broken families and that they were likely to have more previous criminal convictions than they actually did. In addition, both college students and police officers believed that rapists tended to recidivate within a short period of time, e.g. 1-3 months, which is much shorter than the time that actually took for them to recidivate. Finally, suggestions for future research were made.

Our study was carried out to develop the severity-adjustment model for length of stay in hospital for percutaneous coronary interventions so that we would analysis the factors on the variation in length of stay(LOS). The subjects were 1,011 percutaneous coronary interventions inpatients of the Korean National Hospital Discharge In-depth Injury Survey 2004-2006 data. The data were analyzed using t-test and ANOVA and the severity-adjustment model was developed using data mining technique. After yielding the standardized value of the difference between crude and expected length of stay, we analysed the variation of length of stay for percutaneous coronary interventions. There was variation of LOS in regional differences, size of sickbed and insurance type. The variation of length of stay controlling the case mix or severity of illness can be explained the factors of provider. This supply factors in LOS variations should be more studied for individual practice style or patient management practices and healthcare resources or environment. We expect that the severity-adjustment model using administrative databases should be more adapted in other diseases in practical.

This study was conducted to develop a web-based learning contents that assists nursing students' clinical practice on operating room nursing and to examine its learning effects. Based on contents and need analysis, 6 learning modules were developed regarding nursing care in surgical operation and operating equipments. In order to verify the effects of the program, this study employed a quasi-experimental pretest-posttest control group design. Knowledge was significantly higher in experimental group that was enhanced by the web-based learning contents than that of the control group (p<.001). However, there was no significant difference between the two groups in self-directed learning. Experimental group had significantly higher motivation toward learning, which was examined posttest only, compared to control group (p<.001). These results support that the implementation of an web-based learning contents need to be continued as an effective educational material but we need more research to establish how this can be effectively implemented in a students' practicum.

Distinguishing aphasia in stroke patients and observing the subtle linguistic characteristics associated with it primarily requires the use of instruments that provide reliable assessment results. Additionally, examiners should be fully aware of how to use those instruments. This study examined 46 stroke patients for aphasia and assessed the reliability of their diagnoses according to examiners whose medical fields were different from each other. Furthermore, a comparison was made between the reliability before training and that after training. To this end, 46 stroke patients were tested for aphasia and in terms of their speech disorder degree by 3 groups, each of which consisted of 12 professionals (3 SLP, 3 neurologist, and 3 nurse). In the result, a rating of 'acceptable' was given for speech intelligibility tasks and the voice quality of /ah-/ prolongation, and other sub-tests were marked as 'good-excellent' by the experts with different areas of medical expertise. For the tasks marked as 'acceptable', the subjects were video-trained for 3 weeks and the differences were compared before and after their training. Consequently, the differences in the examiners' ratings in the speech intelligibility tasks showed a significant decrease and the accuracy of their voice quality ratings showed a significant increase. In the result of research on the correlation between the accuracy of the sub-test ratings and the amount of clinic experience, speech therapists developed more accuracy in rating a picture description task and a speech intelligibility task as their experience accumulated. Meanwhile, doctors and nurses showed more accurate ratings in picture description tasks with greater clinical experience. The results of this study suggest that assessing the neurologic-communicative disorders of stroke patients requires ongoing training and experience, especially for speech disorders. It was also found that the rating reliability in this case could be improved by training.

The purpose of this study is an measurement of the skin dose of a patient by using the OSLD(optically stimulated luminescent dosimeter) under several irradiation conditions of the X-ray beam for diagnostic radiography. The measurements of skin dose were performed for head, chest, and pelvis. And test of reproducibility was carried out at the chest. As a result, we obtained the skin dose at forehead of head to be 1.30 mSv. The skin doses at xiphoid process, breast and apex of the lung of the chest were acquired 0.92, 0.52 and 0.70 mSv, respectively. And we obtained the skin doses at the left pelvis and the right pelvis to be 2.78 and 3.08 mSv, respectively. As for reproducibility, a coefficient of variation was 0.033. The skin doses were exhibited the values corresponding from 1/100 to 1/17 of the dose limit of the public(50 mSv) at the deterministic effect. In order to make accurate measurements of the skin doses for each tube voltage, the measured values have to multiply by the displayed values of reader by a correction factor. The energy response of the OSLD with the tube voltage will be studied in the near future.

This research aims at investigating the factors that affects the wearing of the nuclear protection equipment by radiology students. We measured the factors related to the wearing of the nuclear protection equipment based on the theory of planned behavior (TPB). We collected 192 survey records from 230 radiology students in Kwang-ju and Chun-nam providence who finished the clinical training. Based on Logistic Regression analysis, we found that the wearing of the nuclear protection equipment is statistically more probable as the level of study is lower, the scale of practicing hospital is smaller, the attitude rating is lower, and the rating of perceived behavioral control is higher. We argue that the development of educational program considering factors like the perceived behavioral control is required to enhance the degree of wearing the nuclear protection equipment in the clinical training of college students.

This study aimed to figure out the change of exposure dose to the radiologist according to the C-arm angle change. For the exam it was fixed with 101 kvp and 4.9mA for the exposure time with 3 seconds and 5 seconds respectively. C-arm Tube was located both under and over, then the average was taken after performing for 5 times with the change of angle from -30 degree to 0, 30, 60 and 90 degree. The detector measured in 160cm high from the position of the radiologist who operates the C-arm. The measurement was shown its highest result at -30 degree followed by 0, 30, 60, 90 from the highest order. Over tube method is higher than under tube method. Therefore, to reduce the exposure dose of the radiologist, it is required for using under tube method instead of over tube method. When the angle change is made, it is recommended to use the angle that tube is growing further apart from the radiologist. And it is also necessary to shorten exposed time as much as possible to create the same quality image and also to reduce the exposure dose.

For success in E-learning, support from a learning environment that enables learners to perform self-directed learning more effectively is assumed. However, most existing e-learning systems do not maximize the improvement in learners' self-regulated learning ability because they only partially accommodate factors that can facilitate self-directed learning. In this paper, a web-based e-learning system is designed and proposed that enables support of an enhanced self-directed learning environment by providing various learning methods, evaluation methods, learning content levels, and strategies for learning motivation in various conditions, and synthetically reflecting them. To validate the effectiveness of the proposed system, it was applied to the subject of data structures in a university course, and an online survey was conducted with the students. The results indicated that the proposed system can support a learning environment in which students can perform more effective self-directed learning, enhancing their learning ability.
