Background: This study was conducted to examine the academic achievements of first year medical students in one medical school based on their characteristics and student selection factors of admission. Methods: The admission scores of student selection factors (Medical Education Eligibility Test [MEET], grade point average [GPA], English test score and interview) and demographic information were obtained from 61 students who had interviewed (multiple mini interview [MMI]) for admission (38 graduate medical school students in 2014, 23 medical college-transfer students in 2015). T-tests and ANOVA were used to examine the differences in academic achievement according to the student characteristics. Correlations between admission criteria scores and academic achievements were examined. Results: MEET score was higher among graduate medical students than medical college transfer students among student selection factors for admission. There were no significant differences in academic achievement of first grade medical school between age, gender, region of high school, years after graduation and school system. The lowest interview score group showed significantly lower achievement in problem-based learning (PBL) (p=0.034). Undergraduate GPA score was positively correlated with first grade total score (r=0.446, p=0.001) among admission scores of student selection factors. Conclusion: Students with higher GPA scores tend to do better academically in their first year of medical school. In case of interview, academic achievement did not lead to differences except for PBL.

The aim of this study is to investigate the awareness and satisfaction level of school meal services by elementary school students and their parents. Approximately 97.2% of student-subjects have agreed on the necessity of a free meal service for school lunch; 44.3% of student-subjects voiced the need to provide free meal services in order to eliminate discrimination of low-income students. Over one-third of student-subjects (36.7%) cited nutrition as the main benefit of providing a free meal service. The majority of parent-subjects (95.1%) have recognized the need for a free meal service in school; approximately 37.3% of parent-subjects responded to need the free meal service in order to eliminate the discrimination of impoverished students. Both student- and parent-subjects expressed a high level of satisfaction with the quality of ingredients and the type of soup/nutrition provided. Student-subjects insisted on better food hygiene and a new menu, but cited the noisy cafeteria as a problem associated with school meal services. In addition, approximately 56.5% of student-subjects responded to the need for nutritional education in school. Parent-subjects were primarily concerned with hygiene regarding the preparation of school meal services, noting the temperature of foods as the biggest problem in school meal services. The majority of parent-subjects (88.1%) responded to the need for the nutritional education in school. Results of this survey indicate that school meal services can be improved by increasing menu options and increasing food hygiene.

To prepare basic data for oral health promotion of high school students through the survey of the recognition of oral health care, a questionnaire survey was conducted for 268 students. Statistical analysis was conducted using the SPSS 11.5 with ${\chi}^2$-test, fisher's exact test, t-test and logistic regression. The obtained results were as follows 1. The average of the high school student's oral health knowledge was $13.12{\pm}2.06$. Statistically school girls were higher(pE0.05) than school boy's oral health knowledge(male: 12.91, female: 13.35), tooth brushing frequency(male: 4times or more-15.4%, female: 4times or more-29.8%), and preventive dental visit(male: 8.1%, female: 17.5%). 2. More than 70% of high school students was concerned about oral health. According to the self-judgement of oral health, more than 50% of them was answered that they wasn't sure of oral health. 3. Only 13% of high school students received oral health education and 80% of them recognized oral health manpower's education needs. 4. The logistic regression analysis illustrated that high school student's preventive dental visit was independently associated with the self-judgement of oral health. The odds ratio was 3.0 and statistically significant.

As the dropout rate of university students is gradually increasing, the studies on exploring the status, characteristics, reasons, and countermeasures of dropout of university students are currently grabbing high attention. This paper analyzes the relationship between the admission types and dropout of university students, mainly focused on engineering students. The analysis shows that the dropout rate of engineering students admitted through the scheduled-time admission procedures is quite higher than that of students admitted through non-scheduled-time admission procedures, the dropout rate of engineering students admitted from the vocational high schools is higher than that of students from the academic high schools, and the dropout rate of engineering students admitted from the liberal art high school tracks is higher than that of students from the natural science high school tracks. From the results, we could find out that student-support programs need to be carefully provided for the engineering university students according to their admission types and underlying backgrounds.

Objectives: Students' life changes substantially as grade increases. It implies that risk factors that trigger students' smoking may not be consistent across grades. Most previous studies on student smoking have considered grade simply a control variable. This study examines which and to what extent risk factors are differently associated with smoking initiation according to grade level among high school students in Korea. Methods: Data from the Korean Youth Risk Behavior Web-based Survey (KYRBWS) conducted by the Korea Centers for Disease Control and Prevention (KCDC) in 2007 and 2008 were analyzed in this study. Results: Among boys, school location, school type and pocket money etc. significantly influence smoking initiation in the first grade than in any other grades, but the strength of the association decreased as grade increases except academic performance. Among girls, most independent variables were associated with smoking initiation in the second grade except school location, pocket money per week and academic performance. Conclusions: Our results suggested that the variables related smoking initiation in Korean high school students were notably different by grade and gender. These findings can serve as the basis of policy recommendations with regard to school efforts to prevent student smoking.
