Purpose: Mood disorders such as depression and bipolar disorder are a major mental health problem in college students. We investigate the prevalence of depression and bipolar disorder and the relevance of risk factors for these mood disorders among one college freshmen. Methods: The subjects were 2,865 college students who entered one university located in Seoul and Ansung in 2009. We used BDI (Beck Depression Inventory) for depression assessment and K-MDQ (Mood Disorder Questionnaire) for bipolar disorder assessment. Demographic and socioeconomic factors were measured by questionnaire. Height, weight, blood pressure, total cholesterol, complete blood cell count, and liver function test data were obtained by physical examination for freshmen. Chi-square test and multiple logistic regression were performed to analyze the possible risk factors for depression and bipolar disorder. Results: With different BDI cutoff value, 16 and 21, the prevalence of depression was 8.7% (male: 7.6%, female: 10.1%) and 2.4% (male: 2.5%, female: 2.3%), separately. 'Low economic status', 'urban birth place', and 'low grade at entrance' were significantly associated with depression. Using the original cutoff criterion, defined as clustering of 7 or more symptoms that caused moderate or severe problems, the prevalence of bipolar disorder was 1.3% (male: 1.4%, female: 1.1%). The risk factor of bipolar disorder was academic fields (art fields). Conclusion: Depression and bipolar disorder are common disease in college freshmen. Therefore, Campus-based mental health service program is needed to help with prevention of and early intervention of these mood disorders.

The purpose of the study was to investigate the effectiveness of dynamic software in solving high school analytic geometry problems compared with traditional algebraic approach. Three high school students who have revealed high performance in mathematics were involved in this study. It was considered that they mastered the basic concepts of equations of plane figure and curves of secondary degree. The research questions for the study were the followings: 1) In what degree students understand relationship between geometric approach and algebraic approach in solving geometry problems? 2) What are the difficulties students encounter in the process of using the dynamic software? 3) In what degree the constructions of geometric figures help students to understand the mathematical concepts? 4) What are the effects of dynamic software in constructing analytic geometry concepts? 5) In what degree students have developed the images of algebraic concepts? According to the results of the study, it was revealed that mathematical connections between geometric approach and algebraic approach was complementary. And the students revealed more rely on the algebraic expression over geometric figures in the process of solving geometry problems. The conceptual images of algebraic expression were not developed fully, and they blamed it upon the current college entrance examination system.

Today, most education activities in the junior or senior schools are connected with evaluation. In fact, the evaluation to be accomplished is not the practice of college or university entrance examination but the evaluation analysis of studies accomplishment. In this program, students process their teaming contents according to their level, and they evaluate the accomplishment of learning by themselves. Through the various analysis of evaluation, students who are not in the appropriate level get into the learning plan of low level course. This study makes them notice the lack of teaming ability in time and proposes proper evaluation system which offers right feedbacks and various analysis information for themselves.

In this paper, OMR system based on image processing is developed which improve the performance of conventional OMR system based on line-scan method. Based on this OMR system, real-time OCR system which recognizes alphanumerics is also developed. We propose the OMCR system which recognize the mark and numerals at the same time. Besides, we improve the input system using constrained 7-segment type handwritten numeral instead of mark to solve the problem caused by miswriting the mark. In summary, we verified the reai-time recognition performance of developed OMCR system using application form for admission, answer sheet for college entrance examination and receipt sheet.

Today most of Korean students have no interest in mathematics and lack of confidence in it due to the burden of the college entrance examination, which often results in a failure or a dropout in mathematics in school. Therefore there is a need to diagnose the true causes and to find out a solution. As one of these solutions this study has developed and applied a learning model based upon cooperative group activities for the improvement of mathematical power to classroom. For developing this learning model a variety of research methods are used; questionnaires, observation, and analysis of the interview materials. After the application of this learning model, a lot of positive results in mathematics class have been observed.

Nowaday our school education have been undergone decisive influences by the entrance and examination-oriented education system. To enter universities which belong to top classes in Korean society could be look upon the important success of school education, and it could be equaled to the quality of competent teacher(teacher's professionalism). However, the creativity and knowledge composition ability in the school education will be considered seriously in the coming of 21st century knowledge, information-oriented and globalization society. In this situation, we try to trace about the system and style of foreign school education which is unfamiliar to us, spontaneously we should explore the educational implication which affects to our school education. In this paper, we have reviewed about the present condition and the current situation of Philippines school education(San Beda College Alabang and Rizal Campus). Of course, we tried to observe the practical education activities including a curriculum, teacher, teaching and studying method and student activity. Through this trial, we tried to suggest the effective environment and methodology for the improvement in quality of our school education. Philippines school education 1) could be achieved educational ideas and goals based on the spirit of school establishment, 2) could be gained teacher's professionalism through the system of Coordinator and Prefect, 3) could be conducted learner-centered lessons by the learning method of exploration, discussion, task-resolving, 4) was able to created a pleasant school education through the development and application of a variety of educational programs.

This study aims to investigate factors that are important for Korean language faculty and learners in Thai universities with focus on factors that constitute characteristics of desirable Korean language teachers. This study also analyzes the difference in perception between the faculty and learners to enhance the qualities of Korean language teachers in Thailand. The demand for Korean language learners is explosive in Thailand as Korean language has been adopted as a college entrance examination subject since the 2018 school year. As a result, the Thai government has increased the number of Korean language education institutions to reflect the rapidly increasing demand of Korean language learners, but Korean language education in Thailand has only achieved quantitative growth and has made little in the way of qualitative growth. In this respect, it is meaningful to compare the qualities of the Korean language teachers in the Korean language faculty of Thai universities with the qualities that learners perceive Korean language teachers should have, which ultimately can enhance the quality of Thai Korean language teachers and help the learners to learn more effectively.

The study aimed to investigate what high-school students recognize mathematics textbooks and how they use textbooks in their learning mathematics in and out-of mathematics classrooms. For this purpose, we developed a set of interview questions in order to unpack what high-school students thought about mathematics textbooks and how they intended to use the textbooks for their learning mathematics. Eleven high-school students participated in the interview; the interview lasted for about an hour for each student. The data from the interviews were analyzed. The findings from the data analysis suggested as follows: a) the students seemed to consider mathematics textbooks as crucial medium for a mathematics classroom material and thus, they were likely to obliged to use the textbooks for preparing for not only tests and examination conducted regularly in schools but college entrance examination conducted nationwide; b) however, the students appeared to use the textbooks in limited ways in which they looked into the textbooks to prepare for mid-term or final exam only, not for their understanding mathematical contents as a main resource; and c) the students seemed to realize that they rarely have had an opportunity to develop mathematical thinking capabilities and understand mathematical ideas conceptually through the mathematics textbooks.

Purpose: The objectives of this study were to survey the radiographic exposure parameters, to measure the patient doses for intraoral dental radiography nationwide, and thus to establish the diagnostic reference levels (DRLs) in intraoral dental X-ray examination in Korea. Materials and Methods: One hundred two intraoral dental radiographic machines from all regions of South Korea were selected for this study. Radiographic exposure parameters, size of hospital, type of image receptor system, installation duration of machine, and type of dental X-ray machine were documented. Patient entrance doses (PED) and dose-area products (DAP) were measured three times at the end of the exit cone of the X-ray unit with a DAP meter (DIAMENTOR M4-KDK, PTW, Freiburg, Germany) for adult mandibular molar intraoral dental radiography, and corrections were made for room temperature and pressure. Measured PED and DAP were averaged and compared according to the size of hospital, type of image receptor system, installation duration, and type of dental X-ray machine. Results: The mean exposure parameters were 62.6 kVp, 7.9 mA, and 0.5 second for adult mandibular molar intraoral dental radiography. The mean patient dose was 2.11 mGy (PED) and 59.4 $mGycm^2$ (DAP) and the third quartile one 3.07 mGy (PED) and 87.4 $mGycm^2$ (DAP). Doses at university dental hospitals were lower than those at dental clinics (p<0.05). Doses of digital radiography (DR) type were lower than those of film-based type (p<0.05). Conclusion: We recommend 3.1 mGy (PED), 87.4 $mGycm^2$ (DAP) as the DRLs in adult mandibular molar intraoral dental radiography in Korea.
