This study groups the life content of adolescents according to their time spent during the week and compares their internet use. The data were collected from 2210 middle and high school students, including their life content and hours, and various internet factors such as self-evaluated internet addiction, internet support, internet experience, chatting subjects and the type of internet service. Adolescents were divided into five groups: TV-oriented group, computer-oriented group, peer-oriented group, self-study group and extracurricular institution group. The purpose of internet use, internet experience, chatting subjects, negative aspects of internet and internet addiction were different by adolescents' group type. The peer-oriented group had the highest real self image as opposed to the cyber self image and trusted other's words on the internet. The TV-oriented group had the lowest trust in the internet. The computer-oriented group received the highest internet support and internet experiences, but didn't use the internet for the purpose of information search. The self-study and extra-curricular institution groups used the internet the least, used it to solve stress and were interested in school circles on the internet.

Recently, client computing trend has been changed from server oriented information application to network based P2P(Peer to Peer) services. The conventional client/server method has the merit of accessing abundant information, on the other side P2P has the merit of synchronized community support and information exchange. P2P has four meaning of point to point, peer to peer, person to person and path to profitability. In manufacturing system field, the second meaning is interested. P2P is classified to three type such as conventional client/server, hybrid P2P and pure P2P. The third is really peer to peer concept. The related technologies with P2P are P2P searching, XML, cooperation, IPv6, computing sharing and P2P communication. This paper describes the scheme of P2P and related contents. And through the P2P based technology, a P2P-based collaborative machine and a vertical portal machine are introduced in this paper. The scheme of the machines mentioned above is suggested for cooperation in manufacturing system and u-Manufacturing.

5G 이동통신 서비스가 점차 확대되어감에 따라 P2P 또는 D2D 응용에서 유튜부 비디오 스트리밍과 같은 트래픽 지향의 스트림 제어가 중요한 기술로 떠오르고 있다. 특히 D2D 통신에서 사용자들이 가장 많이 전송하는 데이터 스트림의 타입은 비디오 스트림이며, 이것은 대용량의 전송 스트림의 특징을 가지고 있다. D2D 통신환경에서 이런 종류의 스트림은 트래픽 혼잡의 원인을 제공할 뿐만 아니라 또한 DUE들 간의 서비스 품질을 저하시킨다. 본 논문에서는 비디오 스트림과 같은 동적 미디어 스트림의 끊김현상을 최소화하고 스트리밍 서비스 품질을 최적화하기 위해 TOSS 기법을 제안한다. 제안된 기법은 5G gNB 환경하의 3.5GHz와 28GHz의 대역폭상에서 미디어 스트림의 특성과 트래픽 타입을 분석하여 미디어 스트림을 스케줄링한다. 우리는 시뮬레이션을 통하여 제안된 기법의 성능을 알아보며, 시뮬레이션 결과는 제안된 기법이 다른 비교 기법들에 비해서 성능이 보다 우수함을 보인다.

This study examined the effects of gender, parental support and treatment type on the treatment outcome of adolescent substance abusers. Outcome variable was the successful graduation (or drop) from an Intensive Adolescent Outpatient Program. Adolescents with their parents' support were treated in one of three treatment models (2-weeks Inpatient plus 6 week Intensive Croup-Oriented Outpatient, 8-weeks Intensive Croup-Oriented Outpatient, and 8-weeks Individual-Family Therapy) within a private hospital-affiliated treatment center by managed care practice allowing their own choice (non-random natural assignments). Several hypotheses were tested for main effects by the Log-Linear Analyses for a multi-dimensional contingency table with 440 adolescents (284 boys and 156 girls treated during 1992-l997) from middle-class families with private health insurances. The following results were found. Odds of graduating versus dropping out of the treatment program among : (1) girls were 1.7 times higher than those among boys; (2) adolescents with two-parent were 2.2 times higher than those among adolescents with one-parent ; (3) adolescents with Inpatient plus Outpatient was 1.7 times higher than that of those with Outpatient; (4) adolescents with Individual-Family Therapy was 2.3 times higher than that of those with Outpatient Model. There was no statistically significant outcome difference between the Individual-Family Therapy and the Inpatient plus Outpatient. Implications from the results were discussed. Suggestions were made to improve the treatment components in the areas of gender sensitivity, securing more parental support, alternatives for separation from peer group and integrating new peer groups, and flexibility for the unique needs of individual family. Also, some research questions for future studies were suggested.

Purpose: This study was a literary investigation in the development of an effective team-raised and cultural nursing organization targeting operating room nurses. This was done by grasping organizational features, different types of nursing organizational culture and team effectiveness, and by analyzing the relationships among variables. Method: The participators were 373 nurses. The data was collected between March 10th and April 28th, 2004. SPSS Win 11.0 program was used for data analysis. Results: Results of this study were as follows: A nursing organization at operating rooms was found to have an organizational culture with the characteristic of a centralized power and hierarchy-oriented organizational culture. With respect to a relationship between operating room organizational characteristics and the types of nursing organizational culture, there was a significant correlation in relationship-oriented culture and innovation-oriented culture. In the relation between the types of operating room organizational culture and team-effectiveness, it showed a significant correlation in team-devotion, peer-groupsatisfactional perception of a team's outcome in decreasing order. Conclusion: The organizational characteristic at operating rooms was power centralization and the culture type was hierarchy-oriented. These are factors that have a negative effect on a team-effectiveness-affecting relationship-oriented culture, innovation-oriented culture and work-oriented culture.

Stress affects the type of adaptation required for each case and the type of social support is also different. In order for social support to have a buffer effect on stress, we want to understand how to measure social support and support according to specific stress situations. Therefore, this study examines coping behaviors of community service workers exposed to these job stresses and examines the effect of support system (family support, peer support, superior support) on coping behavior. The purpose of this study is to investigate the effects of stress, coping resources and coping behaviors of community service workers. In this study, self - report method was used to investigate the questionnaire using structured questionnaires. In this study, the statistical program was used for data analysis and hierarchical regression analysis.

The purpose of this study is to empirical case study for the instructional design of flipped classroom by job-capability advancement of IT business majors. A student of IT business school has learned a lot of management educations for four years. But, they don't recognize a connection between school education and business practice. A subject based on the humanities, and social sciences consisted of mostly the memorization. The undergraduate class lack a practice's curriculum by a creative-oriented lesson rather than memorization-oriented. In particular, An IT business is now recognized as a significance emerging IT investment, the Internet of Things, information security, big data and strategy's ERP. For these reasons, it is important for an instructional design for understanding business practices of the students. Accordingly, Flipped classroom with participatory class be needed increasingly for students' practical sense. We will propose a design method of flipped classroom for inspiring business education. In this, new instructional design overturned traditional teaching method. After the student conducts a prior learn at home, school will accomplish a problem solving through question and answer. This design effected a boredom suppress and creative enforcement of student and an intimacy increase of instructor. In addition, A participatory class and reciprocal peer tutoring will be possible by a spontaneous self-directed learning of student. We were designed course of project type based on big data theory and application to target the fourth-year course. In conclusion, the new instruction provided a help to learning synergy between student and lecturer. During the lessons, the student showed improvement of business sense and enhanced problem solving capability. The lecturer has the intimacy through communication interaction with students.
