In this study, the difficulties experienced by secondary preservice science teachers in studying the theory of science education for teacher selection test were studied. At first, questions of the internet cafe for preparing the teacher selection test from January 2008 to June 2009 were analyzed in terms of content area. A survey was also administered to 39 preservice science teachers who took the teacher selection test. The rubric used in this study was developed by the Korea Institute for Curriculum and Evaluation and the Korean Association for Science Education. As a result, the most frequent question areas were 'philosophy and history of science' and 'theories and models of teaching and learning science'. In the survey with the preservice science teachers, the most difficult content area was the philosophy of science. The application of teaching and learning model was also one of the most difficult areas. Based on these results, educational implications were discussed.

The importance of communication which is oriented to interaction, fusion and connection is more increased in the post-information society. The information environment is already realized as interface to reach immediately and freely to the databased information and knowledge. The contemporary libraries execute very important roles as an intellectual infra of modern times to deliver the great human achievement and create new culture. In the mean time, the rapid information-oriented society and the development of digital technology bring out big change in the traditional dispatch and receipt method of information. For this reason, libraries as the community space of visitors integrates physical space - electronic space and reconstructs new temporary culture and value to build the new interface that connects human to human, human to space and human to information. On the premise of these awareness, this study analysis the creative interface factor of Tama Art University New Libraries in Ito Toyo in order to research the function and the application method of modern libraries. And the results are follows. 1)We can make sure the significance of communication and the integration consciousness between digital technology and analogue sensitivity that is the characteristic of the post-information society. 2)We can classify for the creative interface factors by the character as space factor(Arcade, Gallery, Lounge, AV Booth, Cafe), facility/equipment factor(Laboratory, Media, Bar, Info Shelf, Media Seat) and furniture factor(Carrel, Desk, Mag Table, XI Shelf). 3)We can see that these interface factors change the stream of library users and that the library is constructed for library users to create and discovery something easily from books and modern technologies. And we can realize also that these factors are creative installation to lead out naturally the latent liberty sense of users.

The purpose of this study is to investigate the meaning of cultural practices of videogame audience with 'mod'. Videogame audience members are recognized as very active and interactive beings compared with other interpretive media audience members. Especially mod is one of the most dramatic cultural situation of videogame. It's very prominent properties are 'activity' and 'interactivity'. Videogame audience members, so called 'gamers' modify videogame software as their own sake and use it as their own intention. Modifying and playing with videogame, or 'modding' is very strong cultural program of gamer. Mod is one of avant-garde technology but its practice is not always radical. I observed practices of the members of Naver cafe 'Elderscroll' playing . They used mods of for their phallocentric desire. And they construct a hierarchical and top-dowon membership. So advanced technology and cultural media and text from it does not assure the same advanced contents.

As interest increases in health promotion through sports, demand for public sports facilities is steadily growing. However, there is a lack of research on operation and management compared with the supply plan of public sports facility. In this context, the aim of this study is to address problems of management of public sports centers and suggest strategies for vitalizing the facilities through the big-data. The data are collected from web such as news, blog, and cafe for one year in 2015. From the big-data, We can find that the national sports centers and the open gyms showed similar users' behavior but showed different needs. Both facilities have been used as sports and leisure area and have a high percentage of visitors for other purposes such as walking, picnics, etc. However, while the national sports facilities which were used for more specialized programs, the open sports center were used as leisure space.

In this study, I examined the problems of the current barista curriculum and sought how to improve them by feedback from domestic specialized baristas and comparative analyses of the training programs that take place in barista educational institutions. In order to identify problems in curriculum and what to be improved, I gained the opinions of 15 experts who are currently teaching students in barista educational institutions using Delphi technique. To sum up the opinions of experts, working level education of coffee has to be mainly done and substantial educations for employment such as cafe operating technique and marketing are needed. In addition, experts suggested enhancing service courses considering the nature of working in contact with customers and the course for baking goods that takes up a lot of sales. As a result of examining the current curriculum in the institutions for baristas, it seems necessary to supplement these training courses that experts suggested because the educations are very poor.

In many theoretical and empirical studies on the design issues of therapeutic healthcare facilities, spatial configuration that promotes users' wayfinding behavior, has been emphasized as a significant factor to mitigate stressful experiences and to enhance restorative quality in the healthcare environment. This is also applicable to the healthcare setting for children. However, not much evidence has been reported with regard to the relationship between spatial configuration and wayfinding behaviors in this specific setting. Moreover, healthcare facilities for children with physical disabilities need more attention to provide easy wayfinding due to various physical restrictions. The aim of this study is therefore, to unfold the relationship between spatial configuration and visual cognitive qualities of outpatient spaces in the selected children's rehabilitation hospitals in Seoul, by examining visual cognitive attributes such as visibility, accessibility, and intelligibility. In the first phase, the spatial layout of the hospitals was analyzed, with an emphasis on the major outpatient areas such as the entrance lobby, doctors' examination, and physical therapy zones. In the second phase, a space syntax tool was implemented to examine visual cognitive characteristics of the spatial configuration. The spatial configuration parameters measured were integration, integration core, visual isovist field continuity, correlation between integration and step depth, and the correlation between integration n and integration 3. As a result, the integration was higher in the hall type configuration. Circulation intersections acted mostly as integration cores for better visibility. Some areas showed the lack of continuity in the visual isovist fields overlap and irregular correlation between integration and step depth. The intelligibility was higher in the circulation area and social interaction spaces such as a cafe, reception waiting, and therapy waiting areas. Based on the analysis, design implication and possible future improvement were discussed to enhance wayfinding experiences in the hospitals for children with physical disabilities.

Purpose - The primary purpose of this study is to employ effective marketing methods using market segmentation of coffee shops by determining how motivations to visit coffee shops have different impacts on demographic profile of visitors and characteristics of coffee shop visits, so as to draw out a better understanding of customers of coffee market. Research design, data, and methodology - Data were collected using surveys of self-administered questionnaires toward coffee shop users in Daejeon, Korea. A number of samples used in data analysis were 253 excluding unusable responses. The data were analyzed through frequency, reliability, and factor analysis using SPSS 20.0. Factor analysis was conducted through the principal component analysis and varimax rotation method to derive factors of one or more eigen values. In addition, the cluster analysis, multivariate ANOVA, and cross-tab analysis were used for the market segmentation based on the types of motivation for coffee shop visits. The process of the cluster analysis is as follows. Four clusters were derived through hierarchical clustering, and k-means cluster analysis was then carried out using mean value of the four clusters as the initial seed value. Result - The factor analysis delineated four dimensions of motivation to visit coffee shops: ostentation motivation, hedonic motivation, esthetic motivation, utility motivation. The cluster analysis yielded four clusters: utility and esthetic seekers, hedonic seekers, utility seekers, ostentation seekers. In order to further specify the profile of four clusters, each cluster was cross tabulated with socio-demographics and characteristics of coffee shop visits. Four clusters are significantly different from each other by four types of motivations for coffee shop visits. Conclusions - This study has empirically examined the difference in demographic profile of visitors and characteristics of coffee shop visits by motivation to visit coffee shops. There are significant differences according to age, education background, marital status, occupation and monthly income. In addition, coffee shops use pattern characterization in frequency of visits to coffee shops, relationships with companion, purpose of visit, information sources, brand type, average expense per visit, important elements of selection attribute were significantly different depending on motivations for coffee shop visits.

Purpose: Neurofibromatosis 1 (NF1) is one of the most common autosomal dominant diseases caused by heterozygous mutation in the NF1 gene. Mutation detection is complex owing to the large size of the NF1 gene, the presence of a high number of partial pseudogenes, and the great variety of mutations. We aimed to study the mutation spectrum of NF1 gene in Korean patients with NF1. Materials and Methods: We have analyzed total 69 unrelated patients who were clinically diagnosed with NF1. PCR and sequencing of the NF1 gene was performed in all unrelated index patients. Additionally, multiplex ligation-dependent probe amplification (MLPA) test of the NF1 and SPRED1 gene analysis (sequencing and MLPA test) were performed in patients with negative results from NF1 gene sequencing analysis. Results: Fifty-five different variants were identified in 60 individuals, including six novel variants. The mutations included 36 single base substitutions (15 missense and 21 nonsense), eight splicing mutations, 13 small insertion or deletions, and three gross deletions. Most pathogenic variants were unique. The mutations were evenly distributed across exon one through 58 of NF1, and no mutational hot spots were found. When fulfilling the National Institutes of Health criterion for the clinical diagnosis of NF1, the detection rate was 84.1%. Cafe-au-lait macules were observed in all patients with NF1 mutations. There is no clear relationship between specific mutations and clinical features. Conclusion: This study revealed a wide spectrum and genetic basis of patients with NF1 in Korea. Our results aim to contribute genetic management and counseling.
