We propose and implement a personalized tour recommendation system based on ontology. We utilize user's profile, dynamic information on search in the application, web search, and facebook for personalized recommendation. We construct tour database for England based on ontology for a demo service, and recommend tour spot considering an individual preference with tour database. This dynamic and personalized tour service makes it possible for individual to plan one's own tour by considering recommended tour spots for each individual.
Color Image Zero-Watermarking on DCT Domain through Comparison of Two Channels
Kim, HyoungDo ;
The Journal of the Korea Contents Association, volume 15, issue 9, 2015, Pages 11~20
DOI : 10.5392/JKCA.2015.15.09.011
Digital watermarking provides electronic means for proving the copyrights of distributed digital media copies. Research on digital watermarking for images is recently directed toward that for color images extensively used in real life, based on the substantial results in digital watermarking for gray-scale images. Color images have multiple channels, each of which corresponds to a gray-scale image. While there are some watermarking techniques for color images that just apply those for gray-scale images to one channel of the color images, the correlation characteristics between the channels are not considered in them. This paper proposes a zero-watermarking technique that makes keys via combining an image dependent watermark, created through comparing two channels of the color image and copyright watermark scrambled. Due to zero-watermarking, it does not change anything of cover(host) images. Watermark images are robust against some common attacks such as sharpening, blurring, JPEG lossy compression, scaling, and cropping.

In the semi-conductor process, a simulation process is performed to detect defects by analyzing the behavior of the impurity through the physical quantity calculation of the inner element. In order to perform the simulation, Finite-Difference Time-Domain(FDTD) algorithm is used. The improvement of semiconductor which is composed of nanoscale elements, the size of simulation is getting bigger. Problems that a processor such as CPU or GPU cannot perform the simulation due to the massive size of matrix or a computer consist of multiple processors cannot handle a massive FDTD may come up. For those problems, studies are performed with parallel/distributed computing. However, in the past, only single type of processor was used. In GPU's case, it performs fast, but at the same time, it has limited memory. On the other hand, in CPU, it performs slower than that of GPU. To solve the problem, we implemented a computing model that can handle any FDTD simulation regardless of size on the cluster which consist of heterogeneous processors. We tested the simulation on processors using MPI libraries which is based on 'point to point' communication and verified that it operates correctly regardless of the number of node and type. Also, we analyzed the performance by measuring the total execution time and specific time for the simulation on each test.

Oh, Jung-Shim ;
The Journal of the Korea Contents Association, volume 15, issue 9, 2015, Pages 29~36
DOI : 10.5392/JKCA.2015.15.09.029
This study aims to examine the problems that transmissions of an intangible cultural heritage in Korea may be cut off because of the public indifference, low demand for it and lack of government funding and seek ways to revitalize an intangible cultural heritage by increasing citizens' awareness of it and demand for it. According to recent studies, many holders of important intangible cultural properties have a difficulty doing because government funding is not enough to make their living and people who want to learn and pass on traditional skills keep decreasing. Many experts say that governments need to increase citizens' awareness of an intangible cultural heritage and demand for it in the long run to solve this problem, but governments focus on improving condition of holders rather than that. On this account, this study criticizes the government's policy and surveys citizens' awareness of an intangible cultural heritage and demand for it and suggests a plan of revitalizing an intangible cultural heritage.

The aim of this research is to find out how to cope with and manage environmental uncertainty to be effective. Environmental conditions of complexity and change create a greater need to gather information and to respond based on that information. Despite of the governmental campaign 'creative economy, flourishing culture', governmental subsidies are becoming more unstable. The prosperity of culture means that artists can create great works and people can enjoy them without boundaries. This research investigated Boundary-spanning roles through the strategic formulation and implementation. Key factors of strategy are information and knowledge management. Boundary-spanning roles link and coordinate an organization with important elements in the external environment. It is primarily concerned with the exchange of information to detect and bring into the organization information about changes in the environment and send information into the environment that presents the organization in a favorable light. Two themes in this article are that organizations can learn and adapt to the environment and that organizations can change and control the environment.

DOI : 10.5392/JKCA.2015.15.09.096
Recently, the Department has utilized the media facade as a means to attract new customers and promotional tools. In particular, we checked the rate of customer's gender who visited a large department store. The ratio of women's visit is 4.6 times more than men. This can confirm the need to produce a differentiated content of LED media facade by gender. This study are subject to an empirical analysis of differences of perception of evaluation factors of media facade in gender. At first we specified four factors which can evaluate the media facade according to gender by previous studies. There are aesthetics, artistry, comfort and harmony. And the hypothesis was set as "Each factor might be differences between the recognition of their gender" In order to verify a hypothesis the country's large department store was selected and experiment was performed. In the result of the experiment, among the four factors, aesthetics, creativity, and harmony were chosen, while comfort was dismissed. This results confirm that the following factors are needed to attract more women's customer at the department such as combination of space and media facade, combination of shape and color, appropriateness of the information and beautiful place, and directing way of content.

According to the traditional precedent, if a beneficiary who completed a provisional registration as a result of reservation of trade which is a fraudulent act, then assigned the right acquired by the provisional registration to the third party who has no information of the process, and let the third party complete an additional registration transfer the provisional registration, and if the third party completed the main registration on the foundation of the provisional registration, the beneficiary cannot be the other party of the litigation requesting for the cancellation of registration of the provisional registration. As the result, an apprehension that the duty to recovery of the beneficiary could easily be acquitted of a charge has existed. But, it is considered as desirable that the judicial decision judged that the court recognized the qualification of the defendant as appropriate at this case, with a different view from the precedent, and then the defendant can file the litigation against the beneficiary, requesting for cancellation of the reservation of trade which is a fraudulent act.

It has been 1 year since Sewol Ferry disaster occurred in the Gwanmaedo sea of Jindo, Jeollanamdo, on Apr. 16, 2014. The Sewol Ferry Disaster which took 304 lives and had some victims still missed has become the largest tragic accident in Korea since 2010. Although one year has passed since the disaster, there is no psychological communication research on the trauma of the victims' families. This study first investigated the actual state of the Sewol Ferry victims' parents suffering from post-traumatic stress disorder (PTSD) after their losses of children by the disaster. This study revealed that the victims' families suffer from physical and psychological the PTSD but neglect treatment. The PTSD still influences their daily life. It was observed that the victims' families have a lot of difficulties with interpersonal relationship, relationship with co-workers, residence, values, and other kinds of daily life. Given that the victims' families have a great deal of PTSD after the disaster, the academic circle needs to make discussions of the issue actively in order to heal the pains of the Sewol Ferry victims' families who are unattended in our society.

The Journal of the Korea Contents Association, volume 15, issue 9, 2015, Pages 273~284
DOI : 10.5392/JKCA.2015.15.09.273
This study analyzes the effects of the self-esteem on the life satisfaction of 2,040 middle school senior students using the Korean Children and Youth Panel Survey 2012 Data (KCYPS 2012) provided by the National Youth Policy Institute. In the ecological perspectives, this study considers two factors which influence the life satisfaction of the students; one factor is the environmental characteristics like parent intimacy, friend intimacy, teacher intimacy and study adaptation, and the other factor is the individual characteristics. In particular, self-esteem as one of the individual characteristics is divided into two separate categories, positive self and negative self. The two categories are found to have some interaction effects on the life satisfaction at the evaluation level. The effects of the negative self-evaluation on the life satisfaction appear to be different depending on the level of the positive self-evaluation. As the level of the positive self-evaluation becomes higher, the effects of the negative self-evaluation on the life satisfaction decreases. The life satisfaction becomes higher as the level of the negative self-evaluation is lower, and the life satisfaction is not high relatively at the low level of the positive self-evaluation. These results suggest that solving the adolescent's negative self-formation problem can not bring out the positive self-formation and there should be some plans for the positive self-formation more than simply solving the negative self- formation problem in order to improve the life satisfaction.

DOI : 10.5392/JKCA.2015.15.09.329
The purpose of this study was to identify the types of subjectivity on communication styles of nursing freshmen and explore their properties by using the Q Methodology. Fifty nursing freshmen of P sample classified 55 Q-statements into the normal distribution of 11 point scale. Data were collected from May to June, 2015 and analyzed by using PC-QUANL program. As a result, communication styles are identified as 'Open-interaction facilitator', 'Other-considerate listener', 'Tense-sensitive to criticism person', and 'Non-interactive observer'. Open-interaction facilitators proficiently use verbal and nonverbal expressions, openly disclosing themselves and facilitating interactions with others. Other-considerate listeners primarily consider others before themselves, with careful communication. Tense-sensitive to criticism persons are nervous, sensitive to criticism, and are distractive style, so they have difficulties in intimate interaction with others. Non-interactive observers are bystanders who observe others and feel indifferent to interactions, without any self disclosure. The result of this study will be used for developing communication educational programs for nursing freshmen.

Discourse analysis is useful for examining discourse characteristics of dementia patients and differentiating them from normal adults. However, inconsistent tasks, transcription methods and measures have been utilized, thus analyses were inevitably unsystematic. The purpose of this study was to investigate tasks, transcription methods and measures of discourse studies in dementia. Studies on dementia discourses written in English were collected via Scopus database containing abstracts and citations from 2005 to 2014, and were analyzed in detail. From the results, the most frequently used task was 'storytelling-topic'. It was observed that use of consistent transcription conventions rendered more reliable transcription data. Measures could be categorized into coherence, cohesion, productivity, propositional syntactic lexical analysis, and fluency, and each category belonged to discourse processing levels (i.e., processing of conceptual networks, propositions, and natural language units). In conclusion, future research warrants not only utilization of discourse tasks depending on dementia types and features, but also application of consistent transcription conventions. Additionally, measures based on the discourse processing theory would enable us to systematically interpret discourse studies.

Since 1970, MRI has greatly been developing in terms of strength of magnetic field, the number of receipt channels, and short time of examination. With the development of digital systems and wireless network, hospitals have also acquired, saved, and managed digital images taken by various kinds of medical imaging equipment. However, domestic universities fail to provide practice training course independently thanks to expensive practice equipment and high maintenance cost, and rely on clinical training. Therefore, this study developed a MR patient diagnosis program based on Windows PC to help out students before their working in clinical filed. The designed Relational Database of MRI Simulator is made up of seven tables according to functions and data characteristics. Regarding the designed patient information, each stepwise function was classified by the patient registration method in clinical field. In addition, on the assumption of the basic information for diagnosis, each setting and content were classified. The menu by execution step was arrayed on the left side for easy view. For patient registration, a patient's name, gender, unique ID, birth date, weight, and other types of basic information were entered, and the patient's posture and diagnosis direction were set up. In addition, the body regions for diagnosis and Pulse Sequence were listed for selection. Also, Protocol name and other additional factors were allowed to be entered. The final window was designed to check diagnosis images, patient information, and diagnosis conditions. By learning how to enter patient information and change diagnosis conditions in this program, users will be able to understand more theories and terms learned in practice and thereby to shorten their learning time in actual clinical work.

In this study, we proceed if there are any changes in binding ability of receptor-ligand in some degree of SA and in radioactive uptake from the corpus striatum based on small animal experiment in vivo based on the S.A values. By dividing 18F-Fallypride into 3 S.A values(high S.A : 43.29~74 GBq/umol, ordinary S.A : 20.72~29.23 GBq/umol, low S.A : 6.29~8.51 GBq/umol), we injected directly into the veins and performed 90 minutes of dynamic scan using Micro PET. After scanning, we compared and analyzed with Binding Potential (Binding Potential) from the bilateral striatum. high SA and low SA, ordinary SA and low SA showed significant differences. Also, in the image comparison using 18F-Fallypride show high radioactive uptake in the striatum at high SA and ordinary SA, but the radioactive uptake at low SA is lower than other two SA. Since 18F-Fallypride has affinity to dopamine D2/3 pharmacokinetic, the difference of Binding Potentials at decreased level of SA values was not that significant. However, further PET research of the corpus striatum using 18F-Fallypride is necessary because the differences in images and Binding Potentials at 6.5 times smaller SA values compared to high SA value showed were significant.

Though most researchers studying humor in recent years agree that 'incongruity' is essential factor of humor elicitation, they have different views in the course of schema activation in processing humor text. One of the different views on schema activation in processing humor text is wether schemata are activated concurrently or selectively. While concurrent activation view suggests that different schemata are concurrently activated because we perceive them at the same time, selective activation view suggests that different schemata are selectively activated because we use selective attention for their perception. This study was conducted to verify these two different views. We clarified that different schemata were activated in processing of humor text, and we examined whether Vaid's experiment failed or not. Experiment was designed mixed 2 (schema1, schema2)
3 (setup, incongruity, resolution)
(humor, control) factorial design and latin square counterbalancing. As a result of experiment, we got data that different schemata were activated in the course of 'Incongruity' at the same time. Most of all, the activated schemata were kept activation in the course of 'Resolution'. This result suggest that different schemata were activated concurrently.

DOI : 10.5392/JKCA.2015.15.09.541
In this paper, first, we examined the factors which would affect users's intention for accepting Smart Healthcare Service. Second, we analyzed weather the types(health care provider vs. health care recipient) of the users would modulate the factors's influences. The independent variables of the research model are novelty-seeking, self-efficacy, facilitating conditions and security. The mediating variables are the perceived ease of use and the perceived usefulness. The dependent variable is the acceptance intention and the moderating variable is the user type which contains health care provider and health care recipient. As the results of the analysis, we recognized that the self-efficacy of the users would affect the perceived ease of use and the perceived usefulness in the smart healthcare services, but the user types(health care provider vs. health care recipient) did not modulate the factors's influences. We also recognized that the facilitating conditions would affect the perceived ease of use and the perceived usefulness in the smart healthcare services, in particular, the user types modulated the influences in the ease of use. We also recognized that the security would affect the perceived ease of use and the influence was more sensitive in the case of the health care provider. At last, we recognized that the ease of use and usefulness would affect the acceptance intentions. The influence of the ease was more sensitive in the case of the health care recipient. The influence of the usefulness was more sensitive in the case of the health care provider.

The construction industry is a labor-oriented and quality, cost, and schedule performance is effected by technicians. However, the construction industry have faced a labor shortage problem. Therefore, technician graying and no new workers inflow cause labor shortage and decline of worker's skill level. The utilization of foreign technicians instead of domestic technicians has been increased in the construction industry. This paper performed questionnaire survey for 43 managers on 14 project fields to determine the current status and problems of construction technicians and to propose a improvement plan. As a result, most foreign technicians are carpenters and iron workers, but the skill levels are generally lower than domestics. The major problems for foreign technicians are communication and non-skilled. Then, labor productivity and accident rates of foreign technicians are higher than domestics. This paper proposes that skill training programs, language lessons, and multi-cultural programs are effective to improve foreign workers' problems.

In addition, The comprehensive implication tells that the preliminary elderly who wants the urban elderly housing type have a more personal characteristics than other types. So it should be considered according to personal characteristics. Next, when we choose the suburban elderly housing type and predict the demand for housing development, it should not only considers factors such as the Unmarried children, Health status, Current housing size and Plans for economic activity in old age but also considers factors such as the Accessibility, Convenience, Investment and Environment characteristics of elderly housing preference. Next, when we choose the resort elderly housing type which based on the fact that a few detailed parameters of current housing characteristics exist, it should be based on the current housing characteristics of preliminary elderly. In addition, it should consider a pre-investigation for elderly housing preference in order to select the housing type. Because a comprehensive preference such as the comfort, convenience, safety, investment, environmental characteristics is considered as major determinants factors.

This paper presents a quantitative evaluation of water permeability in concrete with cold joint considering mineral admixture and loading conditions. Concrete samples with OPC (Ordinary Portland Cement) and GGBFS(Ground Granulated Blast Furnace Slag) are prepared considering 0.6 of W/C ratio and 40% of replacement. 30% and 60% loading levels for compression and 60% loading level for tension are induced to concrete samples. In compression conditions, the permeability in control case shows
in OPC concrete, and it changes to
(30% of peak) and
(60% of peak). The results in GGBFS concrete shows the same trend, which yields
(30% of peak), and
(60% of peak), respectively. In tensile conditions, the permeability increases from
(60% of peak) while that in GGBFS concrete increases from
(60% of peak). Permeability coefficients decreases in 30% of compressive level but increases in 60% level, while results in tensile level increases rapidly. This shows pore structure in concrete is condensed and with loading and permeability increases due to micro-cracking. Permeability evaluation considering the effects of loading conditions, cold joint, and GGBFS is verified to be important since water permeability greatly changes due to their effects.

This study was conducted to evaluate suppressive effects of black rice aleurone layer extract (BRE) on body fat, serum lipid, and hormone levels in ovariectomized rats. The rats were divided into five groups (n=8/group): sham operated group (S); ovariectomized control group (OVX); ovariectomized group treated with isoflavone 10 mg/kg B.W. (IF); ovariectomized group treated with BRE 30 or 90mg/kg B.W. (BRE-30 or -90). High fat diet (45% calories from fat) was fed to all rats for 12 weeks. Body weight gain, body fat weight, and adiposity index increased in the OVX group, but they significantly decreased in IF or BRE supplementation. Serum triacylglycerol and leptin levels decreased in BRE groups while serum adiponectin level significantly increased compared to that of the OVX group. Hepatic total lipid, triglyceride, and cholesterol levels increased in the OVX group, but they decreased in BRE supplementation (p>0.05). These data suggest that black rice aleurone layer may be a useful food source to decrease obesity and its related diseases by modulating lipid metabolism in estrogen-deficiency model.

The aim of this study is to identify whether college students' self-discrepancy has an effect on their well-being and to verify the moderating effect of social support on the relation between self-discrepancy and well-being. For this study, the preliminary research was conducted in the way that questionnaire tests on self-discrepancy, well-being, and social support were administered to 587 college students in Busan and Gyeongnam province. The test results were analyzed by means of SPSS 21.0 program. First, average and standard deviation were analyzed to examine the general characteristics of self-discrepancy, well-being and social support. Second, correlation analysis was used to examine the relationships between variables. Third, hierarchical multiple regression analysis was used to examine the moderating effect of social support on the relation between self-discrepancy and well-being. The conclusions drawn from the analysis are as follows. First, self-discrepancy had a significant negative correlation with well-being and social support had a significant positive correlation with well-being. Second, contrary to the research hypothesis, social support had no moderating effect on the relationship between self-discrepancy and well-being. Based on these findings, the implications and the limitations of the research findings were discussed, and recommendations for future research were provided.

The purpose of this study is to provide developmental direction of medical education by analysing graduate medical school student's perception structure about 'good doctor' and the difference between graduate medical school student's perception structure about 'good doctor' before and after clerkship. Subject of study is medical students in 1st~4th year. NetMiner 4.0 program, which is social network analysis, was used to analyse. Many of the words that students used to describe good doctor were similar. But especially lots of times they used 'patient', 'treatment', 'competence', 'heart' and a word 'patient' showed highest degree centrality. Higher density of network and mean degree centrality were shown in students who experienced clerkship. 'Diagnosis and treatment', 'medical communication', 'attitudes to patients', 'medical knowledge', 'basic competence' these 5 groups were shown in network of students before and after clerkship in common. In the case of students after clerkship, 'lifelong learning ' groups have been added, so were the 6 groups. Considering the fact that social responsibility, professionalism, medical humanities are emphasized in recent medical education, students have lack of perception structure about good doctor, therefore education of this area needs to be strengthened.

The purpose of this study is to examine the effects of knowledge base and metamemory in children's conceptual implicit memory with category-exemplar-generation task. Subjects were total 180 children of each 60 from Grade2, Grade6 and High school students. They were examined implicit memory with category-exemplar-generation task, knowledge base test, and metamemory test. The data were analyzed using ANCOVA, and Scheffe post hoc test. The result was following: First, as the child grow old, implicit memory primed increased. Implicit memory amount was significantly different between Grade2 and High school students, Grade6 and High school students. Second, as the child grow high knowledge base, implicit memory primed increased. There was a significantly different found between age and knowledge base. Third, as the child grow high metamemory, implicit memory primed increased. These results were interpreted as that the state of the age, knowledge base and metamemory should be an important factorin implicit memory. And current findings suggest that implicit memory can show development if a children's knowledge base and metamemory in developing with age.

The purpose of this study is to investigate the effects of EngageGram which is a motivator of e-learning participation on learners' online participation according to the types of social comparison motive. Research participation was 144 undergraduate students (male: 106, female: 38) who took the course entitled "Creative Thinking." Social comparison motive of learners were investigated by two methods: social comparison motive scales and learners' opinions on EngageGram. As results, there was no statically corelation between the types of social comparison motive by using scales and online participation, however, there was statically differences on e-learning participation according to the types of social comparison motives by analyzing learners' opinions. Learners mostly have self-enhancement motive in a learning context so they are motivated to participate actively by EngageGram. This study provide useful implication in the research area of learning analytics.
