The purpose of this study is to examine the factors that influence school life satisfaction based on personal variables, self-esteem, interpersonal relationships, and perception of the educational environment at a medical school in Korea. The data were collected from 228 medical students who agreed to participate in the study at a medical school. The Dundee Ready Medical Environment Measure (DREEM) and the self-esteem scale by Rosenberg were used. Questions measuring satisfaction of medical school life and interpersonal relationships (with professors, with senior/junior students, and with friends) were asked using a 5 point Likert scale. The data were analyzed by t-test, analysis of variance, and multiple regression analysis. The satisfaction of medical school life of male students was significantly higher than female students and increased with years of schooling. In DREEM, the students' perception of teachers decreased by school years. The relationship with senior and junior students of third year students was higher than other school years. The result of the regression analysis to determine the variables that affect satisfaction of medical school life showed that interpersonal relationships with senior and junior students, the students' social self-perception, and the students' perception of learning were significant. The results of this study will help medical schools in their plans to improve the level of satisfaction for the happiness and successful academic achievements of their students.

This study analyzed the determinants of self-employment exits among the middle-aged and senior adults. For the analysis, we used KLoSA(Korean Longitudinal Study of Ageing) data from the first(2006) to the sixth(2016) and vocational data, which is a retrospective data surveyed in 2007. Among the reasons for exiting the self-employment, we find that the group that went out of their businesses due to management difficulties were more likely to have economic difficulties after the exit. Therefore, we analyzed the determinants of self-employment exits considering the exit reason due to management difficulties. The analysis model used a competing risk regression model that defined the only exit due to management difficulties as failures. As a result, the significance of gender, age, and education variables, which were well known as determinants of exiting the self-employment, disappeared. On the other hand, we find that the prior experience in the same industry tended to lower the risk of exiting the self-employment. To summarize the results, we suggest that we need some ways to help the middle-aged and senior adults who start their own businesses without any experience in the same industry to prevent them from failures.

Der p 2, which is a major allergen of house dust mite, plays an important role in the pathogenesis of allergic disease. There is controversy regarding whether Der p 2 binds to Toll-like receptor 4 (TLR4), and its inflammatory effect has not yet been elucidated. In the current study, we examined the interaction of Der p 2 with TLR4 and the effect of Der p 2 on cytokine release in THP-1 cells and lymphocytes. Among house dust mite extracts, recombinant TLR4 protein interacted with Der p 2. The overall structure of Der p 2 is characteristic of the immunoglobulin superfamily and contains ten ${\beta}-strands$, forming a ${\beta}-cup$ fold with two anti-parallel ${\beta}-sheets$, and a short 310 helix. The two sheets can be separated, further allowing the formation of a large internal pocket, which is narrow and suitable for binding large flat molecules such as lipid-like molecules. Der p 2 caused increased secretion of IL-6, IL-8, and MCP-1, which are neutrophil survival factors, in human monocytic THP-1 cells in a time-dependent manner. Der p 2 also induces the release of cytokines in normal and allergic lymphocytes. Supernatant after treatment with Der p 2 inhibited neutrophil apoptosis. In coculture of lymphocytes with neutrophils, Der p 2 inhibited spontaneous apoptosis of allergic neutrophils. In summary, Der p 2 binds to TLR4 and induces an inflammatory response such as cytokine secretion in immune cells. These findings may enable elucidation of allergy pathogenesis by specific allergen of house dust mite.

In this paper, we propose an efficient method for a university mentor-mentee system to assist the completion of a student's major study in a university. The proposed system connects undergraduate students from a freshman through a senior by the cascade type, and a mentor student in a sophomore or a junior year acts as a mentee at the same time. A mentee can get help not only from his direct senior mentor but also from all his senior mentors. Based on this, all students can be organically connected to each other, and then the students in the department can establish intimate relationships among themselves, which will in turn induce a good learning environment in the major education. The proposed mentoring system has been actually applied to the department students of computer engineering. The questionnaire surveys have been conducted targeting the participated student mentors and mentees, and then the operation results of the proposed system are analyzed in this paper.

Purpose: To evaluate the reliability of preoperative and postoperative distal metatarsal articular angle (DMAA) measurements and to determine whether such reliability is different in accordance with the foot and ankle fellowship and the number of years in practice. Materials and Methods: Between July 2012 and June 2014, a total of 20 patients (24 feet) were treated with proximal chevron osteotomy and distal soft tissue procedure for symptomatic hallux valgus deformity. DMAA were measured twice with an interval of two weeks between the preoperative and postoperative dorsoplantar radiographs by four observers; two of whom were foot and ankle surgeons (A and B), one knee surgeon, and one senior resident. The intraobserver reproducibility and interobserver reliability were assessed by intraclass correlation coefficients. Moreover, the limit of agreement between the preoperative and postoperative DMAA measurements were assessed using a Bland-Altman plot. Results: The intraobserver reproducibility of the foot and ankle surgeon A, knee surgeon, and senior resident improved from 0.796, 0.575, and 0.586 preoperatively to 0.968, 0.864, and 0.864 postoperatively, respectively. The interobserver reliability of foot and ankle surgeon A-B, foot and ankle surgeon A-knee surgeon, and foot and ankle surgeon A-senior resident improved from 0.874, 0.688, and 0.677 preoperatively to 0.971, 0.917, and 0.838 postoperatively, respectively. Conclusion: The intra- and interobserver reliabilities for DMAA measurement improved after proximal chevron osteotomy. Therefore, the necessity of additional procedures to correct the increased DMAA should be reevaluated after proximal chevron osteotomy in the hallux valgus with an increased DMAA.

BACKGROUND/OBJECTIVES: This study analyzed the quality of lunches provided in senior leisure service (SLS) facilities and compared institutional foodservice (IF) and non-institutional foodservice (non-IF). SUBJECTS/METHODS: Data of 390 adults aged 65 years or older who ate lunches in SLS facilities were analyzed using the information from the 2013-2017 Korea National Health and Nutrition Examination Survey. The participants were classified into IF (n = 129) and non-IF (n = 261) groups according to meal type provided. The intake of major food groups, energy and nutrients, and nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR) were analyzed. The diversity of meals was evaluated by food group patterns, dietary diversity score (DDS) and dietary variety score (DVS). Energy intake was adjusted in model 1, while energy and sex were adjusted in model 2. All confounding variables were adjusted in model 3. RESULTS: The intake of seafoods (P < 0.001 in models 1, 2, and 3), seaweeds (P < 0.01 in models 1 and 2), and dairy products (P < 0.05 in models 1, 2, and 3) was significantly higher in the IF group. No significant difference existed in energy intake; however, the intake of all nutrients except carbohydrate and vitamin C was significantly higher in the IF group. NAR of all nutrients, excluding vitamin C, was higher in the IF group, and MAR was also higher in the IF group (P < 0.001 in models 1, 2, and 3). The IF group had significantly higher DDS and DVS than the non-IF group (P < 0.001). CONCLUSIONS: The lunches provided in SLS facilities were better in terms of quantity and quality when provided through IF than through non-IF. More systematic foodservice programs should be implemented in SLS facilities, especially in facilities wherein users prepare their own meals.
