The objective of this study was to evaluate microbiological Quality of HACCP application in elementary school foodservice operations. Microbiological Quality of utensils and non-heated foods such as salad was measured two times at five elementary schools in Daegu. The two experimentations differed in that after the first experimentation employees were educated and trained on HACCP based sanitation standards with a goal of improving microbiological Quality of foodservice. Microbiological Quality, time, and temperature were evaluated at three critical control points (CCPs)： washing and disinfecting, personal hygiene and non-cross contamination. Micro-biological Quality was assessed using 3M petrifilm to measure total plate count and coliform group. The first experimentation showed low microbiological Quality due to cross contamination of utensils and cooking gloves; high microbiological count of the garlic, powdered red pepper, and ginger; and not thoroughly washing and disinfecting vegetables. In the second experimentation, microbiological Quality was greatly improved by washing and thoroughly disinfecting raw ingredients and utensils, and using good personal hygiene. However, microbiological Quality of seasonings was still low. Immediate corrective actions were required in one of the foodservice operations that was assessed. These results strongly suggest that foodservice operations should address non-heated food Quality. It is essential to measure microbiological Quality regularly and continually train and retrain employees on hand washing and disinfecting raw ingredients. Further studies are needed to determine whether pathogens are present in raw vegetables and seasonings.

Since no course is offered in the area of professional ICT(Information & Communication Technology) in the high school curriculum, high school students do not have the opportunity to learn about the ICT engineering area and the possible career paths in the field. Due to this problem, high school students are not motivated to choose ICT majors at university level, and in turn, the ICT departments are struggling to recruit qualified students. In this paper, we present an R&E (research and education) model to mitigate this problem. We also present a case study on the program following the model offered by "H" university in collaboration with a local high school. Through the program we provided high school students with design and development experiences to solve engineering problems related to the ICT area and tried to attract their attention to ICT majors. The participants of the R&E program were able to experience the systematic engineering design process, ICT tools, teamwork, and communication skills through problem solving procedures. Based on three years of observation and the survey, it was found that more than 76% of students were motivated highly by ICT and engineering majors via the program. The main contribution of the paper is that we have proposed and proved the R&E program model and applied the ICT R&E model to a program to attract qualified students to ICT majors.

Using flight simulator tasks with 48 air force cadets, this research examined the effects of pilots' flight skill and self-esteem on risk-taking behavior in the context of social comparison with their cohorts. Flight skill and self-esteem were assessed for individual cadets and three conditions of social comparison (upward-, downward-, and no-comparison) were devised. Flight simulator situations inappropriate for further approach or landing were designed to assess pilots' risk-taking behavior. Weather conditions in the simulator were inadequate to make a landing and the recommended strategy was to break off the approach and attempt a go-around. In this experiment, pilots' risk taking was measured in terms of their approach altitudes; the lower approach altitudes indicative of the higher risk-taking. Our results showed interaction effects of flight skill, self-esteem, and social comparison on risk-taking behaviors. For pilots who were either high or low in both self-esteem and flight skill, social comparison had no effect on risk-taking behavior. However, pilots with high self-esteem but low flight skill showed more risk-taking behaviors in social comparison conditions. And, pilots with low self-esteem but high flight skill showed risk-aversive behaviors in the downward-comparison condition.

This study investigates how 'multi-perspective' can be utilized in animation. For this goal, 1 used the traditional techniques of Korean folk paintings called 'Minhwa.' Most 'Minhwa' works, employ 'multi-perspectives', instead of linear perspective of the Western tradition that has been only taught to students under the formal education system. In Minhwa parts of reality are not only stylized but also fragmented and combined within the same frame. Other common techniques of 'Minhwa' include frontal view, bird's eye view, and inverse-perspective, which are of ien combined in one single work. The purpose of this study is to develop a working principle and practically apply it to , an animation piece based on the Korean folktale of the same title. In doing so, I have proposed a way to reconstruct and revitalize the traditional art form in the age of digital technology and have concluded that 'Multi-perspective' in 'Minhwa' can be utilized in other contents such as animation.'Multi-perspective' in 'Minhwa' is a rich source that has numerous cultural applications.

Dr Lillehei (1918$\sim$1999) pioneered cardiac surgery with his landmark operations using cross-circulation in 1954 and 1955. With his dedications to open heart surgery, he is generally considered to be the father of open heart surgery by many medical historians. Dr Lillehei expanded his contributions to cardiac surgery with training 134 cardiothoracic surgeons at the University of Minnesota Hospital and he trained an additional 20 surgeons at the Cornell Medical Center. Dr Lillehei's trainees came from all over the world and Dr YK lee (1921$\sim$1994) of Seoul National University was among them. He joined the University of Minnesota Hospital in 1957 as a part of the Minnesota project. During his stay for two years, in addition to experimental research, he learned clinical cardiac surgery as part of Dr Lillehei's team. In 1959, after returning to Korea, Dr Lee began his career as. a full-time cardiac surgeon with establishing the Division of Cardiac Surgery at Seoul National University. Hospital. Yet he encountered many difficult barriers in the process. During that time, Dr Lillehei was willing to share his experience and he provided many valuable resources for cardiac operations. With Dr Lillehei's kind help, the open heart surgery program was gradually and successfully established at Seoul National University Hospital. These two surgical titans from across the Pacific Ocean died in 1994 (Dr Lee) and 1999 (Dr Lillehei). They are gone, yet the proud Korean people have not forgotten them.

In order to investigate the quality status of fried-frozen Korean meat ball products during retail distribution, VBN value, TBA value, pH and metmyoglobin ratio were determined for 117 samples collected in Seoul area during the period of May to September, 1995. Most samples maintained relatively good quality, but one sample of a company showed $32.5mg%$ of VBN value and 0.65mg/kg of TBA value which indicate the early stage of spoilage. Correlation coefficient between metmyoglobin ratio and TBA value was highly significant. Samples closer to shelf-life limit tended to show higher VBN value, TBA value, metmyoglobin ratio and pH. Out of the surveyed samples, 35% were on retail shelves of temperature above $-14^{\circ}C$, while only 18% were being sold at temperature below $-18^{\circ}C$. It is concluded that prepared frozen foods should be stored at the recommended temperature of $-18^{\circ}C$.

Various geological structures are found on the slope of Bangnim district in Pyeongchang, Gangwon-do, based on the Paleozoic Joseon Supergroup Limestone. The recumbent fold observed on the slope is a very rare geological structure that has not been found in Korea, and has important academic value in exploring the formation process of the Paleozoic geological structures in the Gangwon region. In this study, discussed the geological value of the geological structure observed on the slope of the road, and studied the management method of rockfall problem slopes. The state of development of recumbent folds has conservation value in geological scarcity and specificity. Preservation management measures should be prepared through the protection of slopes and measures to reduce of rockfall risks as geoheritage with an important value in geology science and education. Furthermore, it is expected to be preserved and utilized as a geopark.

In accordance with the increasing possibility that the new and reoccurring epidemics continuously appearing abroad flow into Korea, it is very important to evaluate the efficiency of quarantine management projects of National Quarantine Station. This study adopted the pairwise comparison approach using the analytical hierarchy process(AHP) that has been recognized with its scientific adequacy for allocating the weight, the relative importance of evaluation components. AHP technique is evaluated to be distinguished in measuring the impact by making hierarchy of, simplifying and systemizing the complicated multi-criteria decision making problems. The weights by evaluation indexes were 0.2 in the organization evaluation field and 0.8 in the service and program field. The quarantine business showed the highest value, 0.45, in the service and program field. The indexes were classified into the upper category (organization evaluation field, service and program evaluation field) and lower category (input/process/result/quarantine field, inspection field, hygiene management field, pathogenic organ investigation and monitoring field, epidemics prevention promotion/education field). The evaluation indexes that were finally selected were applied to the actual businesses in National Quarantine Station. Next, the minimum evaluation indexes were selected and so the evaluation system on the businesses in National Quarantine Station was more systemized.

The Honolulu Strategy is a framework document to address marine debris issue globally. The Fifth International Marine Debris Conference held in March 2011 and organized by NOAA and UNEP catalyzed the development of the Holonulu Strategy. Goals of the Strategy are to reduce the amount and impact of land-based, sea-based, and accumulated marine debris. A set of strategies for each goal were provided for education and awareness, legislation, and alternative technologies. The Strategy also lists indicators that could be used to evaluate outcomes of strategies. The adoption of the Honolulu Strategy by the international community has led the international organizations such as GPA, IMO, and CBD to strengthen their responses to the marine debris issue. UN has also set up specific actions that will be implemented until 2025 through its resolutions on marine debris. Recent global developments related to the marine debris issue might lead to a change in the character of the international marine debris management from the current soft law regime to a mandatory one. The Honolulu Strategy could provide a guideline when the Korean government formulates the Second Basic Plan for Marine Debris Management, especially with its prevention-oriented approaches, utilization of scientific policy development tools, and adoption of evaluation system using performance indicators.
