To investigate current status of the elderly meal service program, community centers nationwide were surveyed for congregate meal services. The survey was conducted during the month of December 2002 by mail using self-developed questionnaire on administration, staffs, funding, and meal service management. Only 95 out of 356 community centers (27%) answered and returned the questionnaires, and congregate meal menus were also collected from 20 centers for 492 days. Results were analyzed using SAS package program. In more than half of the elderly congregate meal service programs, following criteria were used in multiple form to allow participation; 65 years old or older, low income, or living alone. All centers served lunch, most of them free of charge, and 88.4% of them provided service 5 days a week. About 79% of the total cost occurred on the congregate meal service was supported by the government. Most of the menus served at congregate meal service were Korean style dish with rice. On the average, each meal provided 3 side dishes including kimchi, in addition to soup or stew. Only 19% of the centers have employed dietitian working for meal service programs; meal menus were prepared by social welfare workers or other non-dietetic personnels in more than 80% of the centers. Food purchasing and food hygiene control was also practiced mainly by social welfare workers or cooks. This study suggests that dietetic professionals are needed to better manage meal service programs for the elderly in both aspects, food hygiene and nutrition. Development of more nutritious menus and determination of appropriate serving sizes for the elderly meal service programs are necessary to meet the RDAs and dietary action guide for the elderly.

This study examines the visitors'evaluations of tourism resources in Insa-dong, which the Seoul metropolitan government has improved recently. This study adopted the method of Importance-Performance Analysis by collecting data through questionnaires. A random sampling of visitors to Insa-dong was conducted in June and July,2001. The survey included questions on the physical and psychological components of Insa-dong's tourism resources. In the case of physical components, eight factors(ancient arts shop, art gallery, atelier, calligraphy shop, pottery arts, traditional tea house, antique shop, traditional clothes) out of thirteen were categorized as 'keeping up the good work'. None of the Physical components was shown as 'low priority'or'possible overkill'. In particular, four factors(restaurant, heritage, Korean-style house and alley, traditional cultural festival) need to be impoved most urgently in terms of visitors'satisfaction. Survey results realize them as high priority in importance but low in performance, thereby designated as, 'concentrate here'. An image of the 'street' showed to be high in importance and identical in performance, so can be categorized between'keeping up the good work'and 'concentrate here'. The results show that unusual outdoor spaces and the festivals of Insa-dong have a significant meaning to the visitors. In the case of psychological components, three factors(general atmosphere experience of unusual atmosphere, appropriateness of stroll time) out of seventeen were categorized as 'keeping up the good work'. Ore factor (shopping) was designated as 'low priority'and not found to be 'possible overkill'. Thirteen factors (various events, possibility of various activity, various flood, richness of play, new experience, education cultural inheritance, parking facilities, resting places, green spaces, meeting places, guide map and information, cleanliness of facilities/convenience) need to be improved mast urgently in terms of visitors' fulfillment. They are perceived as areas of 'concentrate here'. This confirms that attractive events are essential for the recent visitor satisfaction. Furthermore, visitors are not satisfied with its amenity and acccss in Insa-dong despite the improvements. In conclusion, positive impressions, both physical and psychological, should be maintained while factors mentioned to be lacking should be prioritized in order of necessity to improve the image of Insa-dong and solutions need to be found and implemented. The results of this study would be helpful in the planning and management of nsa-dong considering the visitors'requirements.

This paper presents an ARM-based SOC bus transaction verification IP and the usage experiences in SOC designs. The verification IP is an AMBA AHB protocol checker, which captures legal AHB transactions in FSM-style signal sequence checking routines. This checker can be considered as a reusable verification IP since it does not change unless the bus protocol changes. Our AHB protocol checker is designed to be scalable to any number of AHB masters and reusable for various AMBA-based SOC designs. The keys to the scalability and the reusability are Object-Oriented Programming (OOP), virtual port, and bind operation. This paper describes how OOP, virtual port, and bind features are used to implement AHB protocol checker. Using the AHB protocol checker, an AHB simulation monitor is constructed. The monitor checks the legal bus arbitration and detects the first cycle of an AHB transaction. Then it calls AHB protocol checker to check the expected AHB signal sequences. We integrate the AHB bus monitor into Verilog simulation environment to replace time-consuming visual waveform inspection, and it allows us to find design bugs quickly. This paper also discusses AMBA AHB bus transaction coverage metrics and AHB transaction coverage analysis. Test programs for five AHB masters of an SOC, four channel DMAs and a host interface unit are executed and transaction coverage for DMA verification is collected during simulation. These coverage results can be used to determine the weak point of test programs in terms of the number of bus transactions occurred and guide to improve the quality of the test programs. Also, the coverage results can be used to obtain bus utilization statistics since the bus cycles occupied by each AHB master can be obtained.

This case study is based on a fundamental class actually done in the film and video department in Sungkyul University. It aimed at suggesting supportive role for typical film production class in universities in Korea. The list of film styles mentioned in this text is selected from the actual ones for the class and it is focused on utilization of sound and camera. It is ultimately designed to guide students to actual making films. First of all, for example, with a humble camcoder, students are encouraged to record both image and his/her narration which is directly recorded into the built-in microphone. Also directional microphone could be used to experience various positions of 'point-of-hearing'. Regarding camera movements, only distinctive ones out of typical utilization are selected to be dealt with. The movements created by moving vehicle such as dolly or crane beyond the limit of human ability could bring up high imagination of students on movement, besides this could be also easily applied to them for using hand-held technique instead of vehicle. This attitude acquired through the course is important for gettig over the resistance they might have before actual experiencing machinary use in production.

Although Frank Lloyd Wright represents himself as one of the greatest American master architect, the master architects contribution towards the advancement in the modern history of architecture goes beyond just creating landmark buildings. Through out his life, he was the leading architect not only in the area or architectural design but showed his talent in interior architecture, furniture, fabric, lighting fixture, art glasses, tablewares, silver wares as well as in graphic design which should cover all the elements related to the "total design" in architecture. As seen in his architectural design, the "total design" concept also reflects both beauty and logic of the nature and strengthens his theory of the organic architecture design. The research began with finding out the relationship between his architecture, nature and the supporting design elements mentioned above. the purpose of the research is to analyze the relationship of the spatial organization and the design elements in Frank Lloyd Wrights architectural works from the point of "total design" view and provide the valuable guide line for the development of the modern interior design. His design theory, based on the fundamental ideas of the nature, his organic architecture design, and reference materials to support total design concept will be discussed on chapter 2. And on chapter 3, application of the total design in his actual project will be analyzed. The data and analyzation have been completed based on written references and actual visit to the project sites. Frank Lloyd Wright placed highest value on the human beings and enjoyed presenting new ideas and forms to create better environment for the humans through his architecture and interior design projects. While he was presenting new ideas he continued to support design for democracy which has close relationship to the new frontier spirit of America. He was the master architect for the general society with accurate understanding of the life style of the public with design sensitivity shown in his concept of the total design.s concept of the total design.

When restoring a tomb of Songeun, Park Ik that damaged by typhoon in Kobubri, Chungdomyon, Mill Yang, Kyoung Nam in October 2000, a flower designed stone and fresco was discovered. Soneun Park Ik passed the civil service examination in Kongmin dynasty and was consecutively occupied Sajaedogam(司宰少監; regarded as one of second highest official rank). The fresco realistically depicts custom of ordinary people in end of Koryo, beginning of Chosun dynasty that it is considered as an important research material in study of ostumes. Therefore, this research intend to contribute to study of costumes in general public of Koryo that has insufficient study materials through study and analyze of costumes in the fresco with literature research. The number of figures in the fresco is presumed as 26-27 in all but clearly observed figures is only five women and four men and partly damaged figures are two men and two women. Women are worn relatively long yoo that can cover hip as an upper garment and Sang(裳) as trousers. The upper garments are all adjusted to right and has Jikryoung gik (straight collars) but there are strip attached collars or double collars among the Jikryoung gik. The length of Sang reaches to ankle and a waistband is trailed to below the knees. Most of hair are combed in the two sides and made a ring, moreover worn ceremonial coronet, which imply the ceremonial parade. Distinguished from the frescos of Koguryo, there are no women wearing Po(袍) also Yoo with Dae(帶) and without were coexisted. The mens costume is mainly appeared in two types. One(元) is Danryoungpo, Po with round collar and wearing a lozenge shaped crest with a brim, the other is Jikryoung Po, Po with straight collar, and wearing Ballib(拔笠), the latter is a costume of two man presumed as envoys. In the case of Danryoungpo, its length reached to ankle that shows decorum and in Jikryoungpo its length is below the knees that seem to offer practicality for envoys to guide a long journey. Both man and women are in decent cloth with a crest, which simple costume for ordinary people as a Chaksoopo that has comfortable length for movement and narrow sleeves. Songeun Park Ik actively worked under regency of One dynasty that influence of Mongol is seen in mans crest. There are some changes but including womens costume most of cloth are followed Korean traditional costume style.

In this paper, two color contrast evaluation algorithms, W3C and NSSC algorithms are compared and investigated to select proper criteria of the color contrast of text-background color combinations in web documents. The relationship between the color contrast defined by existing formula and the readability rating is not perfect and there is quite a bit of variance, in particular, there is some substantial outlier. I modify the NSSC algorithm to apply all colors and compare the two algorithms to apply same color combinations of web safe colors. A new algorithm considering color temperature feeling as a component of the color contrast is proposed and implemented. As the results of this study, the existing two algorithms are not contradictory to each other, 82% of all color combinations of web safe colors are not proper combinations according to W3C guide which provide severe restriction to select colors in web documents compared to NSSC algorithm. Experimental test shows proposed algorithm is superior to the W3C algorithm with respect to the linearity of relationship between color contrast and readability rating. It means a color temperature feeling is an effective component of a color contrast. But to determine best contribution ratio of the color temperature feeling, further study is required and it is related to Hangul font style and size. The more popular a mobile color display is used, the more important accessibility factor a color contrast will be.

Korea is currently accumulating a large amount of data in public institutions based on the public data open policy and the "Government 3.0". Especially, a lot of data is accumulated in the tourism field. However, the academic discussions utilizing the tourism data are still limited. Moreover, the openness of the data of restaurants, hotels, and online tourism information, and how to use SNS Big Data in tourism are still limited. Therefore, utilization through tourism big data analysis is still low. In this paper, we tried to analyze influencing factors on foreign tourists' satisfaction in Korea through numerical data using data mining technique and R programming technique. In this study, we tried to find ways to revitalize the tourism industry by analyzing about 36,000 big data of the "Survey on the actual situation of foreign tourists from 2013 to 2015" surveyed by the Korea Culture & Tourism Research Institute. To do this, we analyzed the factors that have high influence on the 'Satisfaction', 'Revisit intention', and 'Recommendation' variables of foreign tourists. Furthermore, we analyzed the practical influences of the variables that are mentioned above. As a procedure of this study, we first integrated survey data of foreign tourists conducted by Korea Culture & Tourism Research Institute, which is stored in the tourist information system from 2013 to 2015, and eliminate unnecessary variables that are inconsistent with the research purpose among the integrated data. Some variables were modified to improve the accuracy of the analysis. And we analyzed the factors affecting the dependent variables by using data-mining methods: decision tree(C5.0, CART, CHAID, QUEST), artificial neural network, and logistic regression analysis of SPSS IBM Modeler 16.0. The seven variables that have the greatest effect on each dependent variable were derived. As a result of data analysis, it was found that seven major variables influencing 'overall satisfaction' were sightseeing spot attraction, food satisfaction, accommodation satisfaction, traffic satisfaction, guide service satisfaction, number of visiting places, and country. Variables that had a great influence appeared food satisfaction and sightseeing spot attraction. The seven variables that had the greatest influence on 'revisit intention' were the country, travel motivation, activity, food satisfaction, best activity, guide service satisfaction and sightseeing spot attraction. The most influential variables were food satisfaction and travel motivation for Korean style. Lastly, the seven variables that have the greatest influence on the 'recommendation intention' were the country, sightseeing spot attraction, number of visiting places, food satisfaction, activity, tour guide service satisfaction and cost. And then the variables that had the greatest influence were the country, sightseeing spot attraction, and food satisfaction. In addition, in order to grasp the influence of each independent variables more deeply, we used R programming to identify the influence of independent variables. As a result, it was found that the food satisfaction and sightseeing spot attraction were higher than other variables in overall satisfaction and had a greater effect than other influential variables. Revisit intention had a higher ${\beta}$ value in the travel motive as the purpose of Korean Wave than other variables. It will be necessary to have a policy that will lead to a substantial revisit of tourists by enhancing tourist attractions for the purpose of Korean Wave. Lastly, the recommendation had the same result of satisfaction as the sightseeing spot attraction and food satisfaction have higher ${\beta}$ value than other variables. From this analysis, we found that 'food satisfaction' and 'sightseeing spot attraction' variables were the common factors to influence three dependent variables that are mentioned above('Overall satisfaction', 'Revisit intention' and 'Recommendation'), and that those factors affected the satisfaction of travel in Korea significantly. The purpose of this study is to examine how to activate foreign tourists in Korea through big data analysis. It is expected to be used as basic data for analyzing tourism data and establishing effective tourism policy. It is expected to be used as a material to establish an activation plan that can contribute to tourism development in Korea in the future.
