Over recent 20 years, with socioeconomic development and change of recognition of the population, more people are concerned about their health and appearance. To obtain the change of frequency of malocclusion and the demand for orthodontic treatment, with this trend, 2460 freshmen and students of Yonsei Univ. in 1991, aged from 18 to 21 were examined excluding 187 students who have history of orthodontic treatment, 86 students who are undergoing treatment, 39 students who have too much missing teeth to classify. After analize the frequency of malocclusion and the demand for orthodontic treatment, following results was obtained. 1. Sex ratio in the prevalence of malocclusion was $91.7\%/90.8\%$, male to female, so there was no sex predilection. 2. With regard to Angle's Classification, each percentage of Class I, Class II div. 1, Class II div. 2 and Class III was $61.6\%,\;11.3\%,\;1.9\%\;and\;16.7\%$. 3. Of Class I malocclusion, percentage of crowding was 53.2, this occupied the largest part of single findings and prevalent findings in combinations were also crowding - crossbite and crowding - Protrusion. 4. Of Class I malocclusion, over the portion of$95\%$, Bialveolar Protrusion have arised alone. 5. The distribution of Demands for orthodontic treatment of malocclusion were $41.3\%$ in males, and $51.3\%$ in females.

This study aims to find out how taste recognition differs between two groups of culinary arts students. We conducted a questionnaire survey on minimum sensitivity and minimum tastiness for four basic tastes. The first group consisted of 40 students in their first year, and the second group consists of 56 students in their second year and third year. The survey shows that both groups preferred medium saltiness, and the second group was more favorable to sweetness than the first group. The sweet and the pungent tastes were more favored than sourness and less favored than bitterness by both groups of subjects. The amount of the sample required for minimum tastiness shows that the freshmen had a higher sensitivity than the sophomore and junior students. Contrary to a common belief that people who have more experience in cooking would have a more sensitive taste, this study shows that taste sensitivity does not always accord with cooking experience. Rather, it depends on individual differences and current health status. Further research should be needed for various sensory test method and more kitchen experienced people who has more working years after graduate college.

Purpose: The purpose of this study was to investigate the difference and correlation of interpersonal relationship and purpose-in-life in health allied college students depending on their ability to manage anger. Method: A total of 244 students were surveyed using structured questionnaires. Data were analyzed using descriptive statistics, t-test, and Pearson Correlation Coefficient with the SPSS program. Results: No significant difference of interpersonal relationship was observed between the anger controlled group and the anger uncontrolled group. Intimacy (p=.008) and understanding (p=.017) were significantly higher and openness was significantly lower in the anger controlled group (p=.024). Purpose-in-life was significantly higher in the anger controlled group (p<.001). There was no significant correlation of anger management and interpersonal relationship, however, there was significant positive correlation of anger management and purpose-in-life (r=0.15, p=.017) and interpersonal relationship and purpose-in-life (r=0.29, p<.001). Conclusion: An education program for freshmen who cannot control anger can promote interpersonal relationship and purpose-in-life.

This study aims to identify the characteristics of gas phase problem solving of college freshmen. Four students were participated in this study and solved the problem by using think-aloud method. The thinking processes were recorded and transferred into protocols. Problem solving stage, the ratio spended in each solving stage, solving strategy, misconceptions, and errors were identified and discussed. The relationships between students' belief system about chemistry problem solving and problem solving characteristics were also investigated. The results were as follows: 1. Students felt that chemical equation problem was easier than word problem or pictorial problem. 2. When students had declarative knowledge and procedural knowledge required by given problem, their confidence level and formula selection were not changed by redundunt information in the problem. 3. When the problem seemed to be difficult, students tended to use the Means-End or Random strategy. 4. In complicated problems, students spent longer time for problem apprehension and planning. In familiar problems, students spent rather short time for planning. 5. Students spent more time for overall problem solving process in case of using Means-End or Random strategy than using Knowledge-Development strategy.

A concept test was administered to college students and teachers to identify their understanding of chemical equilibrium and equilibrium shift. The subjects were 53 freshmen in the General Chemistry class, 28 juniors in the Physical Chemistry class and 26 seniors from a university and 10 high school teachers in Seoul. Test items include the calculations of partial pressure and concentration of the gas in the mixture, the equilibrium constant cal-culation and the prediction of equilibrium shift when an inert gas is added to the gaseous reaction system, and the equilibrium concentration calculation and the prediction of equilibrium shift when water or common ion is added to the weak acid solution. The test was focused to identify whether the subjects can predict equilibrium shift using the reaction quotient change for the situations in which Le Chatelier principle is difficult to apply. The results showed that the achievements of teachers and juniors were significantly higher than those of freshmen and seniors. Many stu-dents had difficulties in predicting equilibrium shift using the reaction quotient while they could calculate partial pres-sure and concentration for the same situation. It means they are lack of conceptual understanding of chemical equilibrium shift.

Admissions officer system was introduced in an effort to reject the score-oriented competition and select students on the basis of their individual potential and capacity. The admissions officer system, which was first introduced into the college entrance examination for the 2008 school year in Korea, has been operated by expanding the recruiting level up to 11.8% of the number of the students to be admitted by all colleges. The aim of this study is to analyze the performance of the admissions officer system by analyzing the true picture of school life led by the students singled out through admissions officer screening, and further to inquire into the substantial plan to support the students, who were selected through the admissions officer system, for their successful college life while displaying their potential and capacity As a result of doing research on this, it was found that the freshmen selected through admissions officer screening showed more positive responses in all measurement variables this study selected, such as school adaptability, school satisfaction, and career maturity, learning attitude than other students screened in a different way; in addition, school adaptability and school satisfaction came out as significantly high variables statistically. However, they showed insufficiency in the attitude in class from the behavioral aspect in learning attitude. This study made a suggestion that it's necessary for systematic support and management program to be mapped out and provided in order for the students selected through admissions officer screening to improve their learning attitude as they inspire themselves with school adaptability and school satisfaction.

This study analyzed the academic achievements on above-level testing of mathematics, physics, chemistry, and English in newly entering students of science specialized high schools. It can be expected that newly students of science high specialized schools have reached ceiling level in the middle school mathematics and science academic scores. Above-level testing(or off-level testing) is a test tool used to evaluate student's ability which are above-grade level. In this study, above-level testing tools were used to develop the same type examination paper of the 2013 Korean College Scholastic Ability Test(CSAT) in mathematics, physics, chemistry, and English. The conclusions of this study were as follow: First, the academic achievement level of science specialized high school freshmen were higher the average level of general high school senior because that over 50% of them are within the 5 grade of CSAT in mathematics, physics, and chemistry. In English, 19.3% science specialized high school freshmen have reached within the 5 grade of CSAT. Second, as a result of examining characteristics of academic achievement with respect to units of subjects, in mathematics, it was showed that the academic achievement of 'continuity and limit of a function' unit was higher, 'statistics' unit was lower. In physics, the academic achievement of 'Electricity and Magnetism' unit was higher, 'Waves and particles' unit was lower. In chemistry, the academic achievement of 'compounds in life' unit was higher, 'Air' unit was lower. In English, the academic achievement of 'practical sentence' of reading area was higher, 'Sentence' of writing area was lower. In conclusion, above-level testing provided a good strategy for identifying and determining appropriate programming interventions for gifted students who are two or more grade levels above their age-mates in achievements, aptitude, or ability.
