본 연구는 청소년의 돈을 딴 경험과 도박 유해환경 노출이 문제도박에 미치는 영향 및 성별 차이 분석을 목적으로 수행되었다. 이를 위해 2015년 청소년 도박문제실태조사에 참여한 14,008명을 대상으로 분석을 실시하였다. 주요 결과는 다음과 같다. 첫째, 청소년의 돈을 딴 경험은 문제도박에 정적으로 유의미한 영향을 미쳤다. 둘째, 청소년의 주변에 도박자가 있는 경우나 도박장이 있는 경우 모두 문제도박에 정적으로 유의미한 영향을 미치는 것으로 분석되었다. 셋째, 성별로 구분해보면, 돈을 딴 경험이 문제도박에 미치는 영향은 남학생에게서 더 두드러지는 것으로 나타났다. 넷째, 주변에 도박자나 도박장이 있는 것이 문제도박에 미치는 영향에서는 성별 차이가 나타나지 않았다. 이상과 같은 결과를 바탕으로 청소년의 문제도박에 대처하기 위한 실천적 정책적 방안을 논의하였다.

Objective: This paper aims to describe health promotion (HP) research according to HP activities, strategies, target population, and settings, and to explore challenges for HP to reflect principles and values. Methods: A content analysis was employed for all research reports funded by the Korea Health Promotion Foundation from 2005 to 2011. Content analysis was conducted according to the HP activities and strategies as mentioned in the Ottawa Charter, and by target population and setting. Challenges for HP research were explored by priority actions suggested by the International Union for Health Promotion and Education. Results: The total number of research was 384. The most popular topic was on HP actions for reorienting health services, followed by developing personal skills, creating supportive environments, building healthy public policy, and strengthening community actions. Research focusing on enabling strategies was most dominant among the HP strategies, while both advocating and mediating strategies were unlikely to be studied. An even distribution was found across target populations. The most popular setting was communities, followed by workplaces and schools. Conclusion: HP research tends to be anchored on bio-medical, individualized, and behavioral perspectives. A discussion was made to overcome this tendency by employing HP in social sciences theory and methods.

Group communication is becoming increasingly popular in Internet applications such as videoconferences, online chatting programs, games, and gambling. For secure communications, the integrity of messages, member authentication, and confidentiality must be provided among group members. To maintain message integrity, all group members use the Group Key (GK) for encrypting and decrypting messages while providing enough security to protect against passive attacks. Tree-based Group Diffie-Hellman (TGDH) is an efficient group key agreement protocol to generate the GK. TGDH assumes all members have an equal computing power. One of the characteristics of distributed computing and grid environments is heterogeneity; the member can be at a workstation, a laptop or even a mobile computer. Member reordering in the TDGH protocol could potentially lead to an improved protocol; such reordering should capture the heterogeneity of the network as well as latency. This research investigates dynamic reordering mechanisms to consider not only the overhead involved but also the scalability of the proposed protocol.
