In Korea, recent trends indicate an increase in the volume of the functional clothing market. This study investigated the evaluative criteria and information sources of functional clothing according to gender and age. A total of 756 responses were analyzed using descriptive statistics, MANOVA, and Duncan's test. The main effect of gender on the evaluative criteria and information sources of functional clothing was identified. Compared with male consumers, female consumers gave more importance to price and aesthetic criteria. Female consumers take advice from colleagues and companions, as well as use information obtained from mass media to a greater extent than male consumers. Age was seen to have an effect on evaluative criteria and information sources in purchasing functional clothing. Respondents in their forties and fifties took textile quality and durability more seriously. Information available on the Internet and following the dressing styles of celebrities were preferred by respondents in their twenties.

This study was performed to investigate the awareness of the value on milk and the consumption pattern on milk of elementary, middle and high school students. The subjects were 453 students(129 elementary, 129 middle, and 195 high school students) living in the Seoul area. The results were as follows. The students of this study demonstrated low levels of awareness of the value of milk. They had an awareness of the value of milk about 'convenience', 'healthful', 'safety', 'diversity', and 'useful for snack'. Most students reported drinking milk two to three times a week and 13.2% of students preferred flavored milk rather than plain milk. General preference for milk was significantly higher in elementary school students than in high school students(p<0.001). The degree of satisfaction on milk was significantly higher in elementary school students than in middle and high school students(p<0.001). The respondents answered that their source of information about milk was the mass media. Their source of information from school was very low. In order to increase the consumption of plain milk, milk nutritional education is necessary in schools.

Heat transfer characteristics of evaporative transpiration cooling was investigated experimentally in the range of coolant mass flux, 0.002kg/m$^{2}$.sec~0.015m$^{2}$.sec. Glass beads, sand and copper particles were used as porous media and distilled water was used as a conant. The existence of evaporation zone was confirmed on this experimental conditions and its length increases with increasing article size and with decreasing mass flux. In order to get the low surface temperature, porous materials with high thermal conductivity is preferred when the panicle sizes are same, and small particles with low porosity is effective in case of the same material. Due to the relatively small coolant mass flux, evaporative transpiration cooling system could be stable by the capillary effect.

This study examined activities involving the finding, organizing, managing, and re-finding of information by knowledge workers in Kuwait. This research also conducted a review of the tools needed for effective personal information management (PIM) and assessed perceptions about improving PIM through Internet use. Data were collected through semi-structured interviews conducted among 26 graduates of the Department of Information Studies at Kuwait University. These participants are currently employed in different sectors engaged in a variety of information-related activities. This study's findings indicated that participants gathered different types of information from a variety of sources. This information was stored using several devices and services, including desktop computers, shared drives, clouds, bookmarked websites, e-mail correspondence, and favorites lists. Participants organized information in personal folders according to categories such as subject/topic, time, project, document type, and geographical region. Preferred methods for information re-finding included searching by keyword and browsing through folders. Interviewees reported problems of information overload, fragmentation, and anxiety. Most were active in social media via mobile device, while some of them used Siri or Ask Google to retrieve information. Tools used for PIM included calendars, tasks, schedules, e-mail management tools, clouds, and social networking tools. Participants reported that the Internet helped with personal information management practices, but that some privacy issues arose in this context.

Selfies are a popular form of photography. However, due to physical constraints, the compositions of selfies are limited. We present algorithms for creating virtual portraits with interesting compositions from a set of selfies. The selfies are taken at the same location while the user spins around. The scene is analyzed using multiple selfies to determine the locations of the camera, subject, and background. Then, a view from a virtual camera is synthesized. We present two use cases. After rearranging the distances between the camera, subject, and background, we render a virtual view from a camera with a longer focal length. Following that, changes in perspective and lens characteristics caused by new compositions and focal lengths are simulated. Second, a virtual panoramic view with a larger field of view is rendered, with the user's image placed in a preferred location. In our experiments, virtual portraits with a wide range of focal lengths were obtained using a device equipped with a lens that has only one focal length. The rendered portraits included compositions that would be photographed with actual lenses. Our proposed algorithms can provide new use cases in which selfie compositions are not limited by a camera's focal length or distance from the camera.

The purpose of this study was to examine the utilization of oral health education media among dental hygienists in charge of oral health education. The findings of the study were as follows. 1. In regard to the general utilization of educational media in possession by workplace, age and career, the dental hygienists who worked in public health clinics(42.4%), who were in their 40s and up(341.%) and whose career was six years or more(32.2%) made more use of the educational media. Those who didn't use the educational media cited time constraints as the most common reason(46.1%). 2. Models(53.2%) were highly preferred in most of the institutions where the dental hygienists worked, but the public health clinics(81.8%) and university hospitals(80.0%) were most fond of video clips. 3. Concerning preference for educational media by career, the dental hygienists whose career was between three and less than six years and who had a 10 years or more of career had the most liking for video clips, followed by models. Those whose career was between one to less than three years and between six and less than 10 years showed the most preference for models, followed by video clips. 4. As for their perception of the necessity of educational media, the majority felt the need for the media(87.5%). Regarding difficulties in purchasing necessary educational media, the biggest group pointed out a shortage of information(56.1%).

This study aimed to analyze the characteristics of the bibliographic description of ISBD Consolidated edition published in 2011 and to grasp the considerations in applying the rules of ISBD consolidated edition to KCR4. For achieving this, the four aspects were analyzed such as the description area and data elements, the resource types, the punctuation, and the order of the elements of ISBD Consolidated edition(2011). The characteristics of ISBD Consolidated edition are as follows. First, the content form and the media type area are added in new 0 area and elements are designated by mandatory to confirm to FRBR. Second, content form, content qualification and media type replaced GMD in title and statement of responsibility area. Third, the prescribed punctuations were retained even when this results in double punctuation, and individual square brackets were preferred than entire square brackets when using square brackets to all elements in same area. Fourth, the order of elements in description was set out by patterns of data elements in areas, therefore could reduce the confusion of the order of elements. ISBD Consolidated edition as an international standard would make various rules to maintain the uniformity, but also respects the bibliographic practices of individual countries. Therefore, each country must revise its own rule to conform the ISBD Consolidated edition as well as reflect its unique situation. In Korea, since KCR4 was developed based on the previous edition of ISBD, it should be revised to confirm to the ISBD Consolidated edition. Therefore, this study is expected to contribute to the revision of KCR4.

The column-oriented database storage is a very advanced model for large-volume data transactions because of its superior I/O performance. Traditional data storages exploit row-oriented storage where the attributes of a record are placed contiguously in hard disk for fast write operations. However, for search-mostly data warehouse systems, column-oriented storage has become a more proper model because of its superior read performance. Recently, solid state drive using flash memory is largely recognized as the preferred storage media for high-speed data analysis systems. In this research, we propose a new transaction recovery scheme for a column-oriented database environment which is based on a flash media file system. We improved traditional shadow paging schemes by reusing old data pages which are supposed to be invalidated in the course of writing a new data page in the flash file system environment. In order to reuse these data pages, we exploit reused shadow list structure in our column-oriented shadow recovery(CoSR) scheme. CoSR scheme minimizes the additional storage overhead for keeping shadow pages and minimizes the I/O performance degradation caused by column data compression of traditional recovery schemes. Based on the results of the performance evaluation, we conclude that CoSR outperforms the traditional schemes by 17%.

The embryos of Pinus taeda, P. rigida, and P. taeda ${\times}$ rigida were cultured for adventitious shoot regeneration in vitro. Culture media were modified from Gresshoff and Doy (MGD), Murashige and Skoog (MMS), Lloyd and McCown (MLM), and Schenk and Hildebrandt (MSH). NAA was added to initiation media at a concentration of 0.1 or 0.01 mg/l. BAP was used at the concentrations of 0.1. 0.5, 1, 2, or 5mg/l. Each explant was induced for 3-4 weeks on solid medium. All explants were cultured up to 16 weeks. Illumination was about $1506{\pm}540lux$ at the level of the tissues in the growth room with a temperature of $25{\pm}2^{\circ}C$. A 16-hour photoperiod per 24 hours was used. Half-strength medium was used for all the subcultures. For shoot production by loblolly pine, MMS, MLM, or MSH is preferred with 5 mg/l BAP with either 0.1 or 0.01 mg/l NAA. For shoot production by pitch pine, MMS, MLM, or MSH is recommended with 2 or 5 mg/l BAP with 0.1 mg/l NAA. For shoot production by the hybrid pine, MMS or MLM is more effective with 1, 2 or 5 mg/l BAP with 0.1 mg/l NAA. There were no differences recognized among the species tried in the patterns of bud formation and shoot development. Different composition of media, in major and minor salts or possibly in vitamins, should be tested for the two developmental stages of adventitious shoots ; the induction of shoot buds and the elongation of them into shoots.

Murals in villages revitalize communities and spaces, and are economically efficient. Central and local governments are therefore actively undertaking Mural Village Projects but there are some issues and concerns about the projects for the provision of uniformed landscapes for the regions that are the result of a short-term completion of projects, and instead of cohesion, cause destruction of place identities. In addition, the problem of sustainable landscape management that is the result of low community involvement can be pointed out because the murals are products of government-led projects. The study covered the context of landscape and space change processes from a critical perspective, and focused on Ihwa-dong Mural Village, which is considered the first mural village in Korea and has begun to undergo drastic changes due to attention received from media. The purposes of this study are as follows. First, the study provides data about difference of place identity perception and landscape preference between residents and tourists in Ihwa-dong Mural Village. Second, this paper evaluates the current Mural Village Projects and finds alternative directions to improve the projects by using these data. This paper analyzed tourist hot spots in Ihwa-dong Mural Village by using SNS analysis, a field study and focus group interviews. The difference of place identity perception and landscape preference was examined among three groups: residents, new residents who are invited by Mural Village Projects, and tourists. This study showed that many tourists are focused on landscape areas that were not intentionally constructed projects. In addition, the locations of preferred landscapes and stores overlapped. Meanwhile, using qualitative data analysis, it was found that residents perceived the area as being an under-privileged location, while the murals, a non-daily landscape, largely affected place identity perception of new residents and tourists. For landscape preference, tourists preferred outdoor rest areas, while new residents and residents preferred less. Additionally, new residents and tourists preferred an area's night view while residents made no mention of this. Related to the direction of the projects, three groups showed their dependence on the government. This empirical study is significant from a participatory design perspective and in analyzing the issues for mural villages' landscapes, which are spreading across the nation and proceeding without criticism in urban regeneration. Implications for urban planners and suggestions for the future projects are given.
