The results of this study on Purchase Patterns and Recognition of Processed Foods of School Meal Service Dietitians of elementary, junior and senior high schools in Chonbuk and Deagu Area are as follows : First, the rate of single cooking of the schools surveyed is 100% in Deagu and 66.9% in Chonbuk, and Chonbuk has more small-meal service schools which caused a higher labor cost than Deagu, Secondly, schools in Deagu has purchased not completely processed vegetables and fish and shells than Chonbuk, and Chonbuk(66.9%) has served more Kim-chi products than Deagu(41.6%). Thirdly, nutritional effects and preference have been considered as school dietitians make plans for the menu. Fourthly, the opinions of the school dietitians about processed food are in the order of high sodium content, convenience and the use of preservative, and Chonbuk has responded positively to the articles of future oriented quality, cooking usage and variety while Deagu has thought of it as an economical. The expected effects from the use of processed foods are in the order of saving labor time and student preferences. Fifthly, meat products have been frequently used and more frozen meat products have been used in Deagu and senior high school than Chonbuk and elementary and junior high schools, last, preferences on processed food are in the order of frozen sea food, noodles. dried sea food, processed vegetable and fruit, dairy goods and others. Senior high school dietitians have preferred packed meat products and other frozen processed food more than elementary and junior high school dietitians. The rate of serving processed food had a different depending on the number of students. In this study, dietitians recognize the harmful effects of processed foods over the merits, which means that the rate of using processed food is low. The proper usage of processed foods is thought to improve the preference of students, to have cooking time shortened and to help manage the meal service sanitarily and efficiently. Therefore, companies producing processed foods should do their best to develop safety and health oriented foods to gain the credibility, and the government should make new regulations for people to purchase and obtain processed foods without any doubt.

Video-on-Demand services are increasing rapidly nowadays. The load on servers can be very high, even exceeding their capacity. For popular contents, we can use a Periodic Broadcast (PB) strategy using multicast to serve all clients. Recent development of PB uses multiple channels broadcasting for segments of movies in certain patterns, so that users only need to wait for a small segment to start the service. However, users need higher download capacity to download multiple segments at a time. In order to compensate for this, a proxy server can help to reduce download bandwidth requirements by holding some segments for a certain time. This research will focus on more recent PB schemes that couldn't be covered by previous Proxy-Assisted Periodic Broadcast strategies.

Due to recent increasing of tour, leisure industries, customer's usage of service became more grouped and customer-to- customer interaction became more important. Under these service environment, it is easy to find cases of damaging other customer's service experiences by some customers who use service in selfish manner. Customers called 'Jaycustomer' usually happen in low frequency, but they are serious service failure because they can deliver bad service experience. It seems previous service design tools couldn't handle these cases enough. So it will be good to reinforce to handle these incidents. This study was based on the empirical insights of service design case study by using 'evil persona'. Literature review and survey were performed to find out proper servicescape for 'evil persona'. From analysis, the service environmental factors which affect frequency of negative customer-to-customer interaction were selected. Also, many cases of such negative behavior were gathered and sorted to find types and patterns which affected by selected service environmental factors.

During the last decade, increasing use of technology that facilitates information access has changed academic library services. The emergence of information commons is one of the key changes. Most previous studies on information commons have focused on its conception and role. Whereas, considering information commons as a spatial service, this study aims to examine the influence of information commons on user traffic patterns within the library and perception of the library. As the information commons grew into main library service space and facility, it is necessary to explore what influences information commons have on the behavior and recognition of users. Two methods were used. First, observation method was used to record traffic pattern and user behavior. Second, twenty undergraduates and twelve graduates were interviewed regarding the use and recognition of the information commons and the library. The results of the study show that the traffic patterns were different between undergraduate students and graduate students; the location and structure of facilities influences their movement and behaviors; and the recognition of information commons tends to affect the perception of the entire library. The findings may help librarians improve and plan for library spaces to meet user demands.

This was a qualitative study on medical aid patients to understand the cause and process of statistical difference of health service utilization between medical aid and health insurance patients. The main results were the following; 1) There was few overuse of health service in medical aid patients. The reason of heavy utilization was mainly due to the complicated disease. Some of them were considered to overuse physical therapy and oriental acupuncture. 2) In case of medical aid patients, medical cost was paid by their welfare benefit of government or by the support of family or neighbors. They usually could not adequately use the services of uninsured benefit or large hospitals due to the cost. Some patients just endured the pain. There was still discrimination for medical aid patients in some medical institutions. 3) The health officials and institutions did not provide sufficient information to medical aid patients about the policy of medical cost support. 4) Health policies, such as selective clinic system, medial aid case management, approval of extended care, were considered to contribute in preventing unnecessary use of health service. However, this might limit adequate use of medical aid service. In conclusion, there is little evidence of overuse of health service for medical aid patients, which is different from the previous studies. A new plan is necessary, because medical aid patients thought that the necessary health service was not accessible to them.
