In order to collect basic data for the plan, design, and improvement of teenager leisure space as well as to contribute to the preparation of various youth leisure spaces, this study is to examine and analyze leisure space planning factors under the consideration of leisure patterns changing rapidly in youth activities. We used sufficient amount of questionnaires and a physical environment analysis at downtown parks and Tongdaemun fashion complexes where various leisure activities of teenager are happened. In addition, an importance and performance analysis was attempted on planning factors of each derived leisure space. on sequently, effective and efficient preparation of youth leisure space for desirable youth leisure activities should be carried out after finding out characteristics of teenager leisure spaces, deriving and integrating suitable planning factors for each characteristics, and finally adapting such derived planning factors by performance and importance. The future space for youth leisure should be improved and prepared after mature consideration about importance and performance of planning factors, which are suited for leisure patterns and characteristics of teenager leisure spaces.

The purpose of this study was to evaluate the performance and importance of dietitians' role in order to provide basic information for an efficient foodservice management. This approach was achieved using a variety of quantitative and qualitative informations including general foodservice management, dietitian's role performance and importance. A survey of 453 office and factory foodservices was undertaken and detailed information was collected. Statistical analysis of data was performed using SAS package program for descriptive analysis, 1-test, $\chi$$^2$ test, and analysis of variance. The general characteristics of the dietitians were that 80.20% were aged between 20∼29 and 66.49 had work experience with less than 5 years. And 61.68% were graduated from college. The Importance-Performance Analysis (IPA) technique was used for obtaining information of dietitian's foodservice management practices. By the results of the IPA technique, foodservice attributes with fair to poor performance and high impotance was service management for customer satisfaction. The average scores of dietitian's role performance and importance were 3.33 and 4.03 out of 5, respectively. Dietitians with work experience more than 10 years and aged more than 30 years old had more work performance than those.

The objectives of this study were to determine the recognition of food waste, school lunch leftovers and satisfaction toward school lunch in middle school students in Seoul. Four hundred students were surveyed beginning April, 2007. The results are summarized as follows. The primary means in which students learned about environmental pollution were 'video media' (54.7% males, 39.2% females) and 'by teachers' (23.2% males, 33.0% females). The primary effects on food habits after participating in the school lunch program were 'having a balanced diet' (23.3%) in the females, and 'decreased intake of junk food' (24.9%) in the males. The serving sizes for cooked rice, soup, and meat were higher in the females (3.46, 3.46, and 2,91, respectively) than the males (3.18, 3.29, and 2.73, respectively). The primary school lunch leftovers for one week were cooked rice (4.55), meat (4.35), kimchi (3.84), fish (3.60), vegetables (3.38), and soup (3.08). Importance-performance analysis of the school lunch meal indicated that good taste had high importance, but low performance. Nutritional balance, food safety, cleanliness of tableware and supplies, clean uniforms of employees, and cleanliness of the dining area had both high importance and performance.

International Maritime Organizatin(IMO) has been chosen some of agreements for regulating the international stability criteria of fishing vessels and recommended that each goverment adopts theirs into the domestic law. As a result, 77/93 Fishing Safety Agreement was ratified. Among the above agreement, contents of stability was not only applied to domestic law, but also strenghten considerably compared with existing stability criteria. And even if the calculation guide of stability with recommendations was regualted, Analysis of stability on domestic fishing vessels never have been used according to such a caculation method. Moreover, the caculation of stability criteria caused by strong wind, rolling effect and deck inflow was not considered in the existing basic design program. Therefore, the development of stability criteria program available for such a caculation has been of vital impotance. This research has developed a stability criteria program under 77/93 Fishing Safety Agreement. Also through development of stability criteria program, the stability performance of fishing vessel with 69ton stow-nesting was evaluated.
