The goal of this study was to find the way of reduction on food wastes in the university cafeteria. Four hundred and two students from three universities in Daejeon city were surveyed. The data were analyzed by SAS program. The results were summarized as followings: 24.95% of the total users use the university cafeteria everyday. Reasons for the utilization were listed as time saving 31.40%, near place 26.73%, low price 23.16% and no other place to eat 17.82%. Recommendations for the improvements of university cafeteria were listed as menu variation 38.26%, taste 37.83%, price decrease 10.43%. Female students left more food wastes than male students and most leaving food was side dish than Bab, Guk and Kimchi. The major reason of leaving foods was shown to be influenced by the taste and amount of foods supplied in university cafeteria. And they preferred kimchibock-kumbab to other kinds of bab. But they disliked Flounderjolim, pickled anchovies, Ggonchigui, Ginger, Burdock, Lotus root and Crown daisy. The perception of users on the reduction of food waste was 84.10% of total students. The students who know on the method of food wastes treatment were 58.26%. Improvement for reduction of food wastes of university cafeteria can be summarized to emphasize on taste, menu variation, adequate of serving size, also that should be conduct studies for systematic administration method and standard education for reduction of food waste.

Learning at the elbow of scientist is a well-known educational approach to improve students' understanding of science and scientific practice. This study, in the perspective of legitimate peripheral participation in a community of practice, explores how students' scientific practice and perception could be shifted through R&E program with the development of participation. Data from participant observation for 18 months and in-depth interviews were analyzed based on constant comparative method to extract common characteristics of students' participation and major shifts in their scientific practices and perceptions. Students' development of participation was categorized into three stages: legitimate, peripheral, and full participation. In the stage of peripheral participation, students perceived themselves as mere students and showed passive engagement. They just followed the directions of researchers and didn't know what they should be doing. But through continuous participation, students showed enhanced engagement like voluntary article reading, role assignments, and establishing norms in a community of practice with the reference of scientists'. In this stage of transitional participation, students also showed a deepened perception on everyday life of scientist and the community of scientist. And finally in the stage of full participation, students showed responsibility and ownership on research and continuous efforts to refine their research. They recognized themselves as beginning scientists. With these findings, this paper highlighted the dynamic processes of students' development of scientific practices and identity through R&E participation. It also suggests implications for research programs for education, especially for students who have already articulated a science-related career but still have only foggy notions about science.

Purpose: This study aimed to identify variables influencing the psychosocial adjustment of North Korean adolescent refugees in order to establish a structural equation model and design an intervention strategy to improve psychosocial adjustment. Methods: The subjects included 290 North Korean adolescent refugees aged 16~24 years who were enrolled in alternative schools or regional adaptation centers. They were surveyed using a structured questionnaire. Results: The goodness of fit measures of the model were as follows: $x^2=131.20$ (p<.001), GFI=.93, CFI=.91, TLI=.86, RMSEA=.08, and SRMR=.07. The results estimated from the structural equation model indicated a good fit of data to the hypothesized model, which proposed that stress and emotional intelligence are associated with psychosocial adjustment. The major variables influencing psychosocial adjustment were stress, emotional intelligence, which was a significant direct effect, whereas attitude of parenting showed an indirect effect on psychosocial adjustment through emotional intelligence. These variables account for 50.0% of psychosocial adjustment. Conclusion: It is necessary to develop a program and intervention plan that can enhance emotional intelligence and thereby relieve the stress of North Korean adolescent refugees. The program should also include parenting education so that parents have positive attitude of parenting.

Objectives: The frequency of eating out among adolescents seems to be connected to a high rate of skipping breakfast and be interrelated to various nutritional problems. The purpose of this study was to assess the dietary habits of breakfast and eating out and investigate their relationships in male adolescents. Methods: This study conducted a cross-sectional survey. Dietary habits and eating out status were surveyed among 510 male students at a high school in Incheon and compared according to their breakfast skipping and breakfast type. Results: The percentages of subjects in the breakfast skipping group and breakfast group were 41.0% and 59.0%, respectively, and the breakfast group comprised a Korean meal group (74%) and a convenience meal group (26%). In the breakfast skipping group, the percentage of subjects buying and eating snacks due to hunger was 39.7%. Reasons for eating breakfast among subjects who ate breakfast were because parents prepared breakfast (41.9%) and out of habit (31.5%) in the Korean meal group, in contrast to because parents prepared breakfast (36.7%) and due to hunger (29.1%) in the convenience meal group (P < 0.001). Breakfast preparer was mother (91.4%) in the Korean meal group, in contrast to mother (67.1%) and self (20.3%) in the convenience meal group (P < 0.001). A high proportion of the breakfast group woke up at 07~07:30 or 06:30-07, whereas a high proportion of the breakfast skipping group woke up at 07~07:30 or after 07:30, showing a significant difference according to breakfast skipping (P < 0.001). A high proportion of the breakfast group spent 10,000 won (32.5%) a week eating out while a high proportion of the breakfast skipping group spent 20,000 won or more (28.2%), showing a significant difference (P < 0.01). Conclusions: About 40% of male high school students skipped breakfast and consumed snacks as a solution after breakfast skipping. The students who skipped breakfast spent more money on eating out. These results show that breakfast status may be related to eating out. Therefore, practical education on food choice and meal preparation along with regular breakfast instruction is needed in male adolescents.

Human fibroblast-derived multi-peptide factors (MPFs) have been used during treatments with energy-delivering modalities to enhance energy-induced tissue reactions. Human fibroblast-derived MPFs, which include a range of growth factors and chemoattractive factors, activate and recruit fibroblasts and endothelial cells, as well as promote extracellular matrix deposition, all of which are crucial to wound repair. Interestingly, fibroblasts from different species or anatomical sites exhibit distinct transcriptional properties with high heterogeneity. In addition, the patterns of MPF secretion can differ under a range of experimental conditions. Therefore, the use of allogeneic fibroblasts and proper cultivation thereof are necessary to obtain MPFs that can enhance the epithelial-mesenchymal interactions during wound repair. Moreover, energy-delivering devices should be selected according to evidence demonstrating their therapeutic efficacy and safety on a pathological skin condition and the major target skin layers. This paper reviewed the histologic patterns of post-treatment tissue reactions elicited by several energy sources, including non-ablative and ablative fractional lasers, intense focused ultrasound, non-invasive and invasive radiofrequency, picosecond-domain lasers, and argon and nitrogen plasma. The possible role of the immediate application of human fibroblast-derived MPFs during wound repair was proposed.

Sweetpotato (Ipomoea batatas [L.]) is a globally important root crop cultivated for food and industrial processes. The crop is susceptible to the root-knot nematode (RKN) Meloidogyne incognita, a major plant-parasitic RKN that reduces the yield and quality of sweetpotato. Previous transcriptomic and proteomic analyses identified several genes that displayed differential expression patterns in susceptible and resistant cultivars in response to M. incognita infection. Among these, several sporamin genes were identified for RKN resilience. Sporamin is a storage protein primarily found in sweetpotato and morning glory (Ipomoea nil). In this study, transcriptional analysis was employed to investigate the role of sporamin genes in the defense response of sweetpotato against RKN infection in three susceptible and three resistant cultivars. Twenty-three sporamin genes were identified in sweetpotato and classified as group A or group B sporamin genes based on comparisons with characterized sweetpotato and Japanese morning glory sporamins. Two group A sporamin genes showed significantly elevated levels of expression in resistant but not in susceptible cultivars. These results suggest that the elevated expression of specific sporamin genes may play a crucial role in protecting sweetpotato roots from RKN infection.
