In this study, we have conducted characterization of imaging performance for a flat panel digital X-ray detector using amorphous Selenium and a-Si TFT which was developed by the authors. The procedures for characterization were in concordance with internationally recommended standards such as IEC (international electrotechnical commission). The measures used for imaging performance characterization include response characteristic, modulation transfer function (MTF), detective quantum efficiency (DQE), noise power spectrum (NPS), and quantum limited performance. The measured DQEs at lowest and highest spatial frequencies were 40% and 25% respectively, which was superior to that of commercial products by overseas vendor. The MTF values were significantly superior to that of CR and indirect type DRs. The quantum limited performance showed the detector was limited by quantum noise at the entrance exposure level below 0.023 mR, which is sufficiently low for general X-ray examination.

This study is carried out to investigate the actual meal pattern of liberal high school students, who usually spend most of their time outside their homes preparing for the college entrance examination. The result of which tells the urgent need of extension and improvement in the school provision system. We select a total of 611 liberal high students in the city of Incheon, both males and females, of the first, second, and the third graders. The results are as follows; Only 39.6% of the students have breakfast and 14.7% of the students answer they always skip over breakfast. At lunch time, most of, i.e. 89.9% of the students have lunch and 80.4% of them usually carry lunch with themselves. Seniors show a tendency to have lunch quite earlier than the school-stated time, which signifies that many of seniors should bring more than one lunch to school in order not to lack enough calories. 45.8% of the students among those who do not dispense with supper take supper in the form of lunch. Many other students substitute Ra-myon for rice meal at supper time. As we can induce, the students need between-meal refreshments. 48.8% answer they have a snack more often than not, and 40.2% of them say they need a snack because of hunger. 82.1% of the students usually stay at school almost for 12 hours a day, and they mostly depend on lunch for their two meals. But lunch cannot provide balanced nutrition for them because of its restricted choice of nutrutional elements. The data above make it sure that the extension of the school provision system is really demanded. 86.6% of the students answer they feel the urgency of its operation.

In the sustainable waste management, the necessity of environmental education which improves acquisition of the knowledge, attitudes and values for the environment is being emphasized to help students make environmentally desirable decision and promote responsible environmental behavior. However, the environmental education in high schools, as a whole, would be susceptible to many problems caused by tile educational administration focusing only on the college entrance examination. Therefore, this study modifies and applies a program using four teaching/learning methods (Investigation study, Internet-based learning, Field work, Issue analysis study) which deals with the sustainable waste management as the learning subject for the environmental education, and tries to find its effects on the students' environmental sensitivity and environmental conservation behavior in high schools. The main results of this study are summarized as fellows. First, the waste management program had little influence on the environmental sensitivity of experimental groups, while it had positive effect on their improvement of the environmental conservation behavior. Second, there were little meaningful effect on general environmental conservation behavior, but there were some significant results to environmental conservation behavior related to the sustainable waste management. In addition, positive results were found in ecomanagement and consumerism, whereas there were no meaningful results about in persuasion and legal action, which were sub-domains of the waste management program. Among the waste management programs, the school waste investigation study had the most positive effect on the students' recognition and solution of environmental problems as well as improvement of environmental conservation behavior. The easiest one of the four teaching/learning methods was the Internet-based learning, while the most difficult one of them was the issue analysis study. Consequently, in order to achieve the goals of the environmental education in the academic field, there has to be selected the most suitable one of the teaching/learning methods and to be applied to the class, according to the detailed objectives and loaming contents for the environmental education.

The purpose of this study was to suggest qualitative improvement through various student-centered curriculum's teaching experiences focusing on physical education. For this, class diaries, memos, lesson plans, student reviews, and videos for the past four years (2017-2020) were collected and analyzed from four high schools in kyonggi-do, and six students were interviewed. The common features between each student-centered curriculum were to have many students with the purpose of entrance examination and with concern about time conflicts between class and their dinner. In contrast, the differences between each student-centered curriculum were the required level of writing lesson plan, the level of interest and role of a class supervisor, and educational expected effect of students under a given condition. In summary, pre-education experience should be required and class activity support and various evaluation methods should be also needed.

The domestic cartoon industry has went through rapid reformation since 2010 incurred by the emergence of webtoon. Most of the students in cartoon schools long to become webtoonists rather than published cartoonists. Cartoon education in middle and high schools rather focuses on webtoons. The growth of webtoons in private education, excluding college entrance examination, is even more promising. In the same train of thought, the number of webtoon private education institution has surged exponentially. Despite provincial colleges experiencing difficulty due to the lack of the student population, the competition for cartoon admission is intensifying. However, college education often maintains curriculums that do not relate to the on-site demands. Cartoon education in the past was mostly carried out through apprenticeship programs. However such programs began to disappear as college education became more common and as people embraced the emergence of webtoons. Instead collective education and author debut programs replaced the old system. Individualization of education is exacerbating as digital writing tools allow individual webtoonists to publish their works on a weekly basis. The background of the growth of webtoon education can obviously be explained by the growth of the market but there are aspects that can't be explained in such a simple manner. This study examines the current webtoon education status and discusses possible methodological and formation development measures for the future. The introduction examines the change in education and market. The main subject examines the current secondary schools and universities cartoon education and conducts a comprehensive study on the various education related changes. This study proposes future directions for universities by looking at the webtoon era and education changes in the conclusion. It also researched how the units of college cartoon education will fuse and deduct practical results via government policies.

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.
