Despite the enforcement of minimum legal drinking age of 18 years of age since 1997, alcohol experimentation among Korean youth is believed to be greater than ever before. The use of alcohol jeopardizes physical, mental, and social development during a person's formative years, thereby endangering successful transitions from adolescent to adulthood. Even infrequent use of alcohol may result in intoxication and acute consequences, especially among youth, who may have low tolerance due to their smaller body size and may lack experience with the effects of alcohol. Using self-report questionnaire data collected from 1,697 highschool students nation-wide, the drinking behavior among Korean high school students and the relation between adolescents' alcohol expectancy and adolescent alcohol use patterns were examined. Results indicated that gender and the type of school(academic or vocational) were significant effects on the drinking behavior(drinking frequency, experience of drunkenness, the amount of alcohol consumed, experience of binge drinking and that of problems due to drinking). Male students than female students, and students of vocational schools rather than those of academic high schools reported more alcohol experimentation. Also, positive alcohol expectancy proved to have a significant relation with alcohol use among high-school students. That is, students who reported to think alcohol would have a positive effect on socializing, aggressiveness, relaxation of tensions, and enforcing sexual ability tended to drink more, to experience more binge drinking and more drinking problems. Variables of gender and the type of school also were found to have significant effects on alcohol expectancy. Males and students of vocational school held ideas of positive outcomes on drinking than others. Implications for further study on developing prevention programs are presented.

This study is an empirical research based on data analysis obtained by surveying 655 adult men and women. The notable findings are as follow: First, overall, individuals' perception of extramarital affair is negative, but about 16.4% respondents have a positive perception of it. Second, the respondents have a more critical perception of their spouse's extramarital affairs compared to their own. Thirdly, the less critical perception of extramarital affair, the more acceptance of my extramarital relationship, the less tolerance of my spouse's extramarital relationship regardless marital status. Forth, while the less tolerance of spouse's extramarital relationship, the less openness to extramarital sex among unmarried group, the more acceptance of my own extramarital relationship, the more openness to extramarital sex among married group. Lastly, individuals' perception of extramarital relationship does not directly affect the openness to extramarital sex only among unmarried group, however, the correlation between the perception of extramarital affairs and the openness to extramarital sex is fully mediated by the effect of unacceptance of spouse's extramarital affairs. The moderating effect of marital status is proved.

This study is to examine how activities using local multi -cultural resources and world geography lessons using the CCAP(Cross-Cultural Awareness Programme) affect students' multi-cultural understanding. Activities using local multi-cultural resources were carried by visiting in an alien worker community, volunteering in multicultural center, attending on UNESCO ASP(Associated School Program), and making radio broadcasting program associated with 'SCN FM' which is a local broadcasting station on the weekend. And world geography lessons using the CCAP were conducted with 5 classes including orientation by inviting foreign instructors from that place after reconstructing the Southeast and South Asia unit of the countries such as Pakistan, the Philippines, Myanmar and Cambodia. According to twice questionnaire survey conducted before and after activities using local multi-cultural resources and world geography lessons using the CCAP, it appeared that students had familiarity more than before through direct meeting with foreigners inside and outside classroom, and understood and respected other cultures by acquiring contextual regional knowledge. In the end, multi-cultural activities and world geography lessons using the CCAP contributed to students' global citizenship, which overcame prejudice toward third world cultures. Like that, if world geography classes provide continually students with opportunities to experience directly diverse cultures inside and outside classroom, world geography overcome negative image that it transmit decontextual regional knowledge and is regarded as the subject that is very fit for nurturing global citizenship based on contextual knowledge, consideration and tolerance needed in global and multi-cultural society.

The purpose of the present study is to qualitatively explore childcare teachers' attitudes toward gender sensitivity education for early childhood. The study recruited 227 teachers and directors working in childcare centers around the Seoul metropolitan areas. The study utilised the interpretive science paradigm and visual methods for data collection, and thematic analysis examined the attitudes of 227 participants. Gender sensitivity education include gender flexibility and sexual orientation. Most participants showed positive attitudes toward the gender flexibility education. They regarded the gender flexibility as a topic socially accepted, suitable for early childhood development, and easy to implement. They also believed that the gender flexibility education would encourage the individuality of children. On the other hand, 53.3% of participants showed negative attitudes toward tolerance education regarding sexual orientation. Opponents expressed that an issue of sexual orientation did not reach a social consensus. They also worried that the topic is not developmentally appropriate for early childhood, and difficult to teach young children because of insufficient educational materials. At the same time, 40.5% of participants expected Korean society would embrace diverse sexual orientations in the future, and early childhood education would help young children adapted to changing contexts. This study discussed theoretical concepts of gender sensitivity, listened to childcare teachers' voices about education of gender flexibility and sexual orientation, and suggested more appropriate gender sensitivity education for early childhood.

A Controlled Ecological Life Support System(CELSS) is essential for man to live a long time in a closed space such as a lunar base or a mars base. Such a system may be an extremely complex system that has a lot of facilities and circulates multiple substances,. Therefore, it is very difficult task to control the whole CELSS. Thus by regarding facilities constituting the CELSS as agents and regarding the status and action as information, the whole CELSS can be treated as multi-agent system(MAS). If a CELSS can be regarded as MAS the CELSS can have three advantages with the MAS. First the MAS need not have a central computer. Second the expendability of the CELSS increases. Third, its fault tolerance rises. However it is difficult to describe the cooperation protocol among agents for MAS. Therefore in this study we propose to apply reinforcement learning (RL), because RL enables and agent to acquire a control rule automatically. To prove that MAS and RL are effective methods. we have created the system in Java, which easily gives a distributed environment that is the characteristics feature of an agent. In this paper, we report the simulation results for material circulation control of the CELSS by the MAS and RL.

In this paper, a new image watermarking algorithm is proposed which can hide specific information of an ID card's owner in photo image for preventing ID's photo forgery. Proposed algorithm uses the image segmentation and the correlation peak position modulation of spread spectrum. The watermark embedded in photo ensures not only robustness against printing and scanning but also sufficient information capacity hiding unique number such as social security numbers in small-sized photo. Another advantage of proposed method is extracting accurate information with error tolerance within some rotation range by using $2^h{\times}2^w$ unit sample space not instead $1{\times}1$ pixels for insertion and extraction of information. 40 bits information can be embedded and extracted at $256{\times}256$ sized ID photo with BER value of 0 % when the test condition is 300dpi scanner and photo printer with 22 photos. In conclusion, proposed algorithm shows the robustness for noise and rotational errors occured during printing and scanning.

This study is a clinical single case study of the application of Theraplay approach for the treatment of children with eating disorder based on Polyvagal Theory. The first research question is how children with eating disorder change through Theraplay. The second research question is to analyze what the therapeutic factors are for changes in children with eating disorder. To do this, I used a qualitative case study method that explores a small number of cases closely and reveals the case deeply. As a result, the client has a sense of security in Theraplay session, expands the window of tolerance and develops a social engagement system. Through these, client become increasingly adaptable and overcome eating disorder. The results of this study can contribute to neuroscience validation of the counseling effect.

User requirements for access and authentication increase daily because of the diversification of the Internet of Things (IoT) and social structures. The increase in authentication needs requires the generation of new passwords. Users want to utilize the same passwords for memorization convenience. However, system administrators request each user to use different passwords, as well as passwords that include special symbols. Differnet passwords and including special symbols passwords seem to exceed the tolerance range within your memorization skills. It fetches a very negative consequences in terms of password management. This paper proposes a preference symbol password system that does not require memorization by users. First, a survey is conducted to prove statistical safety, and based on this, an evolution-type password system that uses preference symbols is designed. Preference symbol passwords show superiority with respect to installation cost and convenience, compared with conventional non-memorizing password systems such as biometrics, keystrokes, and mouse patterns.
