Most existing mobile distance learning systems are asynchronous ones that allow students to download lecture video and presentation material. However, there are a few synchronous real-time mobile distance learning systems that support slide, annotation, feedback from student, and lecture video and audio at the same time. These live mobile distance learning systems have an advantage of supporting real-time interaction between students and a lecturer thereby making students understand the lecture better. But, they also have a disadvantage in the sense that they don't allow students to experience the past lecture. This problem can be solved by recording and replaying lecture session. So far, there are few mobile distance learning systems that support session recording and replay. This paper presents a synchronous mobile distance learning system that supports video and audio, slide with annotation, and real-time feedback from students, as well as session recording and replay, which is not supported by the existing mobile distance learning systems. The evaluation of the system among students shows that 61.3% of them were satisfied while 3.2% weren't.

The ultimate goal of a hardware design course is to equip the students with the system design ability. However, the majority of the current structures of the design courses are focused on the understanding of the operational principles of each device which is used later as a building block for the design of a system. The shortcomings of this approach are, first, that it is very hard to keep the students motivated to the end of the course where system design concepts are dealt, and, second, the students do not have enough experience of the system design which is usually required in the field. As an alternative to solve these problems, it is necessary to reverse the order of contents of the course. Namely we introduce the high level of the abstract concept of the system design in the very beginning of the course and later by lowering the level of abstraction to the operational principle of the internal devices. In this paper, we propose a new top-down methodology for the introductory hardware design course of logic design, where the design expression and verification in the system-level are introduced first and then detail knowledge on each device is introduced later. Also, we report a case result from a student's working group as part of an extracurricular education in order to verify the validity of our proposed approach

Little is known about sexual autonomy in the light of human sexual health or sexual behavior. The purpose of this study was to increase understanding of sexual autonomy by developing a scale to measure sexual autonomy in college students. The measure was based on the perspective of human beings as having autonomy. A methodological developmental design was used. The study was done in three steps and included concept development through content analysis of relevant literature individual interviews using open-ended questions with 19 college students, item analysis of data from self report questionnaires for item to total correlation, content validity index by professionals and college students, and factor analysis with principal component analysis. Three groups participated in testing the measurement scale; Group A in 1998, a nationwide convenience sample of college students (n=1,163), Group B, college students in 1999 (n=233), and Group C, college students in 2000 who responded to the measurement scale before and after a sex education program (n=216). A series of exploratory and confirmatory factor analyses were conducted to test validity. For analysis of the questionnaires, statistical methods including reliability (test-retest), item to total analysis, content validity, factor analysis for construct validity and t-test for mean difference according to gender, sexual coitus, previous sex education, and pre-post experiment sex education were used with SPSS 10.0. Results: 1. Two stable factors were extracted and these contributed 48.05% of the variance in the total score. All 13 items loaded above .40 on each factor. 2. Factor I with 10 items was named 'control' and factor II with 3 items and was named 'coping'. 3. Differences in sexual autonomy scores for college students according to their experience showed that there were significantly higher scores for sexual autonomy in the post sex education group(t=-10.841, p=.000), but there were no differences according to whether or not they had previous sex education. Female college students had higher sexual autonomy scores than male college students in A or B group (t=-5.933, p=.000/ t=-1.992, p=.048). 4. Cronbach's $\alpha$ was .8603 for the total 13 items with 1,632 college students, .8739 with 232 students, .8333$\sim$.7647 with pre-post sex education with 216 students. This measurement was found to have a high validity and reliability for measuring sexual autonomy in college students. Therefore, the author recommends that it be used to measure the effects of sex education. It is suggested that further study is needed to analyze the relationship between sexual autonomy and sexual behavior.

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.

This study analyzed the factors of stress perception and their patterns depending on the high school students from different types of high school, which include academic high schools and vocational high schools. The data reflected the degree of stress perception according to several factors, which are considered to be related to stress perception, and the study analyzed how differently these factors affected students in each school type. The subjects were 29,380 students from the 14th Korea Youth Health Behavior Survey who meet the purpose of this study. The factors related to stress perception were classified into general characteristics, health behavior characteristics, and health status characteristics. The factors of the study were compared in each group and between the groups. In both school types, stress perception was associated with a number of common factors and some group specific factors. The common main factors related to stress perception were depressive experience, subjective recognition of their health status, subjective recognition of sleep satisfaction, and gender. However, the pattern in which each factor was related to stress perception differed according to the school types. Therefore, efforts should be made to reflect the characteristics of each school type while considering the common factors related to stress perception when making policies for managing high school students' stress.

The purpose of this study is to investigate whether standardized patient(SP) can be used as a reliable examiner in Objective Structured Clinical Examination(OSCE). 4 SPs and 4 faculties who have more than 2 years experience of OSCE scoring were selected. For 1 assignment 2 members of faculty and 2 SPs were designated as raters. SPs were educated for assessing 2 technical skills, male Foley catheter insertion and wound dressing, for 8 hours (4 hours / day, each topic). The definition, method, cautions and complications for each of procedural skills were covered in the education. Theoretical lectures, video learning, faculty demonstration and practical training on mannequins were employed. The 8 raters were standardized for an hour with simulated OSCE scoring using previous videos on the day before the OSCE. Each assessment was composed of 14 checklists and 1 global rate. The allotted time for each assignment was 5minutes and for evaluation time 2 minutes per student. The evaluation from the faculty and SPs were compared and analyzed with the GENOVA program. The overall generalizability coefficient (G coefficient) was 0.839 from two cases of OASTS. The reliability of the raters was high, 0.946. The inter-rater agreement between faculty group and SP group was 0.949 for checklist and 0.908 for global rating. Therefore SPs can play a role of raters in OSCE for procedural skills, if they are given the appropriate training.
