This paper is focused on practical research regarding costume design and arts management that make use of local resources and which are influenced by local culture of Tokuji in Yamaguchi-city, located in a mountainous area in Yamaguchi Prefecture in the western part of Honshu in Japan. We will examine possibilities in fashion design through this study. This was a practical research project, done with cooperation between the university and local industry, with priorities being assigned by the requests of residents of the Tokuji area. In 2011 the Aurinko, Tokuji, Talo (it means the Solar Tokuji Building in Finnish) was decided as the base of activities. Other functions were gradually added on, including a salon for people of the area to exchange ideas and workshops for group discussions. This paper will specifically be focused on the handmade paper peculiar to Tokuji and traditionally used as a material in fashion. The fashion designs developed by this researcher's laboratory were strongly influenced by these styles of paper. These costumes were made with a handmade paper called "Kamiko" in Japan, that is aesthetic sense has been historically cherished. This paper suggests that the affluence and depth of costume design may be expressed not only by directly borrowing from these influences, but also by borrowing the traditional aesthetic sense original to Japan. Thus this paper will examine industry and culture simultaneously, examining in particular the impact of arts management and costume design using handmade paper manufactured locally.

WiBro (Wireless Broadband Internet) system is going to be 9ot down to commercialization. The high portable internet system is able to be connected to the high-speed internet using 2.3 GHz frequency bandwidth, anytime and anywhere. An effective scheduling for UGS, rtPS, nrtPS and BE requiring different QoS, which are service types of the WiBro, is necessary to increase the efficiency of radio channels that are the limiting resource. This paper researches an uplink scheduling that plays a role in assignment for the radio channels from subscribers to base stations. The suggested scheduling provides priorities with each service type considering QoS of them but reserves some bandwidth for lower priory services. After deciding effective amount of bandwidth for reservation, we suggest analytical result on mean delayed time of packet transmission for each terminal, transmission rate for the data, and capacity for uplink. This research can be used as basic data for the standard in the high portable internet system and as data to predict the capacity of base stations.

This research is to aim at presenting arrangement of colors, visual and symbolic through combined coupling ofI-Ging and Sackdong. This combined couplings is attempted to be approached by the following 4 conceptual steps :ⅰ) Is it appropriate to even try to coupleI-Ging with Sackdong\ulcorner ⅱ) Is the basic structure of Kwai an object of stripe colorizing\ulcorner ⅲ) What are the fundamental colors for this purpose\ulcorner ⅳ)combined of Kwai and the fundamental colors. Theoretical background for this study is as follows.ⅰ) Color accord and arrangements of existing Sackdong. ⅱ) An attempt to coupleI-Ging with Sackdong The purpose of this research is to expand concrete concept of Sackdong, which is to be utilized not only in costume design, but in the whole realm of design, by presenting feasible application of stripe coloredI-Ging. The summary of conclusion of this research is as follows. A. Is this aforementioned attempt academic\ulcorner B. Standardization of stripe-coloring is essential. Furthurmore we can conclued that the under-standing ofI-Ging and its basic philosophical background and the fundamental mechanism of colors in traditional costumes is necessary condition for standardization of Kwai. Along this path, however, conditions to be satisfied and priorities to be given depend upon the decision of an individual or a group. In my view, sripe-colorizing of 64 Kwais ofI-Ging followed by intuitive matching of colors with the in-terpretation of Kwais seems to be the most appropriate solution.

The primary objective of this research is to explain how to implement the Service Oriented Architecture (hereafter SOA) enabled Enterprise Resource Planning (hereafter ERP) system successfully for service industries. An implementation of the ERP system help many organizations to alleviate the difficult job of supporting inflexible or legacy systems that in most cases result in cost increases, data redundancy and inaccuracy, and various inefficiencies. However, the ERP system is losing its market share rapidly to the cloud computing system which utilizes the Software-as-a-service (hereafter SaaS) and SOA. The SOA is an approach to integrate various types of IT resources to leverage existing ERP system, while at the same time building an infrastructure that can readily respond to new business environment and offer new dynamic applications. The companies that implement this system have less of a need for the kinds of all-in-one ERP system that have dominated the back office for decades and can move freely to best-of-breed applications. This research will identify the benefits and costs of the SOA enabled ERP system through case studies and its impact on competitive priorities such as cost, quality, delivery, and flexibility.

Purpose: The objective of this research is to investigate and analyze the relationship between physical residential conditions and occupants' responses in apartment buildings by POE(Post-Occupancy Evaluation). The analysis results from this research will help to identify the indoor residential problems and find design solutions for improving overall residential indoor residential environment. Method: The occupant survey was conducted at four different apartment complex area at Cheongju City, Chungbuk Province, Korea. Combination of unbalanced indoor environmental conditions in residential building had difference of occupants' responses according to occupants' characteristics, such as gender, age, and so on. The survey collected data regarding the occupants' EQ(Environmental Quality) priorities to determine the weight of each environmental-quality factor (lighting, acoustic, thermal and indoor air quality). A paired comparison method was used to determine the weight by comparing the relative importance of the two factors based on occupant's survey response. Result: The output from this research is useful to understand the residential environment, occupants' satisfaction, preference, and identifies the current residential problems and finds an architectural solution in apartment buildings.

This study was carried out to show how the Analytic Hierarchy Process technique could be used in setting the priority among selected diseases to increase the range of health insurance benefit. Thirty experts, including doctors (group1), experts for preventive medicine or public health(group2), and representatives of the insured(group 3), participated in the study panel that is conducted for priority setting. They were asked to evaluate the priorities among 6 selected criteria and then 42 selected diseases. The results were as follows; First, representatives of the insured think that the magnitude of out-of-pocket payment should have high priority while doctors think that effectiveness of treatment should have high priority. Second, all experts think that catastrophic diseases such as malignant neoplasm, major heart disease, and cerebral vascular disease should have high priority in health insurance coverage even though there is little difference among groups. These results can be useful to establish a systematic strategy for expanding health insurance benefit package.

This study was performed to evaluate the appropriateness of resource allocation based on the ranking of health center function. Through the Delphi processes, health center functions were ranked in order of importance as follows; planning and research, followed by health education, health promotion, management of chronic diseases, health screening tests, welfare activities, mental health services, medical personnel management, medical services, prevention of communicable diseases, maternal and infant health services, housekeeping, management of oral hygiene, nutrition services, surveillance for community health services, family planning, and administration of the health center. In relation to the above priorities, the allocation of manpower was not appropriate. Even though the expert groups emphasized on functions such as planning and research, health education, and health promotion, they inputted more personnel for administration of a health center, maternal and infant health services, and medical services which were evaluated with lower importance. The budget allocation showed the same trends as the above. Although the functions such as planning and research, health education, and health promotion, and management of chronic diseases were evaluated highly, the budget was allocated accordingo to the the results of the former fiscal year rather than on the importance of function. However the budget for nutrition services, surveillance for the community health services, family planning, and administration of a health center was allocated according to priority. Based upon the above findings, community health center should be given the opportunity to make their own ranking of health center function and to allocate their resources including personnel and budget in order to improve the responsibilities and roles of the community health center.
