The comprehensive vibration assessment program(CVAP) of APR+ nuclear power plant(NPP) is classified as non-prototype, category II with Palo Verde NPP as valid prototype. In this paper, CVAP for first plant of APR+ NPP is proposed. The Control Element Assembly(CEA) shroud of APR+ NPP is different from that of Palo Verde NPP. And the Core Support Barrel(CSB) outer diameter and the flow rate of normal operation of APR+ NPP are larger than those of Palo Verde NPP. Vibration and stress analysis program should be conducted to establish test acceptance criteria. Limited vibration measurement program should be implemented to establish the margin of safety, demonstrate the satisfaction of test acceptance criteria and confirm the similar vibratory response between the APR+ and Palo Verde NPP. Because of the change of normal operation condition, the nominal differences between APR+ and Palo Verde NPP in the structural and hydraulic analysis are studied to determine the measurement locations.

This study investigates the perception of different fabrics by consumers when provided with a video clip with rustling sounds of the fabric. We utilized sportswear products that are currently on the market and evaluated the emotional response of internet shoppers by measuring the physiological and psychological responses. Three kinds of vapor-permeable water-repellent fabric were selected to generate video clips each containing the fabric rustling sound and images of exercise activities wearing the sportswear made of the respective fabric. The new experimental website contained the video clips and was compared with the original website which served as a control. 30 subjects, who had experience to buy clothing online, took part in the physiological and psychological response to the video clip. Electroen-cephalography (EEG) was used to measure the physiological response while the psychological response consisted of evaluating accurate perception of the fabric, satisfaction, and consumer interest. When we offered video clips with fabric's rustling sound on the website, subjects answered they could get more accurate and rapid information to decide to purchase the products than otherwise they do the shopping without such information. However, such rustling sounds somewhat annoy customers, as proved psychological and physiological response. Our study is a critical step in evaluating the consumer's emotional response to sportswear fabric which will promote selling frequency, reduce the return rate and aid development of new sportswear fabric further evolution of the industry.

Despite the rapid increase in the number of foreign students, there has been a lack of research to help them adapt to Korean food culture and develop healthy eating habits. This study examined the dietary habits and problems of foreign students studying in universities of Korea. Although 97.0% of the 604 people surveyed live in dormitories, the visiting rate of the school cafeteria was low. In addition, only 30.2% of them ate three meals a day, and the frequency of eating midnight snack and convenience store foods was high. International students were positive about experiencing new Korean food, but food satisfaction in Korea was not high because of the difficulties in food selection due to religious problems and maladjustment to Korean sauces and seasonings. Information on Korean eating habits was obtained mainly from other foreign students from the same country (49.5%) and the Internet (33.8%), and there was very little interaction with Korean students at meals. The ratio of subjects who ate halal foods was 33.3%, and they were shown to have difficulty obtaining halal foods in Korea. Therefore, based on the results of this study, a support program should be developed in order to improve the dietary habits of international students.

The line simplification method based on the turning function is studied in this paper for conversion of ground plan data to geospatial data to update the digital map. This method eliminate vertices effectively by estimating the length and the angle between the vertices based on the turning function which is useful to express the shape of linear feature. As the result, this method shows high shape similarity, high elimination rate of vertices and 100% of satisfaction degree to the drawing rules. Thus this line simplification method is judged to be effective in updating the digital map with ground plans.

Adjustment of clothing pressure for compression wear is critical to the physiological and psychological satisfaction of the wearer; however, there are limited studies on the practical relationship among extensibility of materials, pattern reduction of compression wear and resultant clothing pressure. This study provides consumers and designers with information on clothing pressure using a screening extensibility test suggested by Ziegert and Keil (1988) even for the final products. As the first step, ten commercial products were collected and their size, extensibility and corresponding clothing pressure were analyzed. It was found that clothing pressure around the waist level could be predicted well from the information of Ziegert and Keil's (1988) % extensibility of the material (Z stretch %) and the actual application of Z stretch amount to the pattern reduction rate (applied % of Z stretch), with an $r^2$ of around 0.80, especially at the waist level. However, it was not simple for the case of clothing pressure around the back of the chest level due to the various design variation and the complexity of the anatomical structure around the trapezius.

Priority setting in national health insurances in major advanced countries and the nation was investigated to draw the criteria for priority setting and suggest the most rational criteria for dental insurance so as to help secure the efficiency of medicare financing and individual's health right and also elevate medical consumers' satisfaction with health insurance. 1. Priorities in national health insurance are different from country to country, depending on the medical security systems, priority introducing conditions, and social environment, but have many common factors. 2. The priority setting criteria for national health insurance in those countries include the following in common: the efficiency, equity, and cost effect of treatment, emergency of treatment, consumption of expense, efficacy of treatment, patient's receptiveness, patient's demand, severity of disease, and patient's responsibility for the disease. 3. In oral diseases, severe diseases including oral cavity cancer are low in rate, and in-hospital treatments are few. From the above findings, it is suggested that dental insurance should establish discriminative criteria for priority setting by reflecting the aspects of dental diseases and system difference between dental and other health insurances and taking account of efficiency of treatment through prevention, cost effect, prevalence and incidence of generalized diseases, and individual's financing burden.

To evaluate the suitability of UML (Unified Modelling Language) in terms of educating novice software engineers, we have conducted a survey study with 102 students who were enrolled in a mandatory course for sophomores in computer science and engineering department. The results indicate that UML 1) has high satisfaction rate among software novices as an education material, 2) improves computational thinking and problem-solving skills, and 3) increases the efficacy of learning when the education program is implemented in the order of UML, programming practice, and physical computing. This paper suggests the applicability of UML as a new education paradigm in software education.
