The purpose of this study is to inquire into the relationships between empirical value, emotional response and behavioral response of skin-SCUBA diving participants. This study sampled 300 skin-SCUBA diving participants in the SCUBA diving pool of the Seoul Olympic Stadium, and the SCUBA diving pool of the Suwon World Cup Stadium by using convenience sampling. For data processing, this study conducted frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis and multi-regression analysis using PASW 18.0 Ver. The concrete results are as follows: First, the empirical value of a skin-SCUBA diving participant was found to have a significant influence on emotional responses. Second, the empirical value of a skin-SCUBA diving participant was found to have a significant influence on behavioral responses. Third, the emotional response of a skin-SCUBA diving participant was found to have a significant influence on behavioral responses.

The purpose of this study is to examine the variables related to the students' e-learning participation that have an effect on learning achievement in e-learning environment of cyber universities. Based on the related research, the followings are derive. First, students' attendance and participation in discussion showed higher correlation with the learning achievement than other participation variables. However, the total studying time in online classes showed lower correlation with the learning achievement. Second, the variables that have an effect on the learning achievement were in the order of students' attendance, participation in discussion, access frequency to online classes, learning progress and number of data uploads. Third, by the learners' background, the difference among the variables that have an effect on learning achievement were found. Based on the results above, this study suggests considerations about participation variables to enhance the learning achievement in cyber universities.

최근 인터넷 통신의 형태가 단순한 텍스트 위주의 데이터로부터 실시간 환경을 요구하는 멀티미디어 데이터 형태로 변하고 있으며, 사용자들간의 실시간적 상호작용이 필요한 원격회의나 인터넷방송. 다중 멀티미디어 게임 등에 대한수요가 증가하고 있다. 이런 응용 서비스들은 동시에 여러 사용자에게 같은 정보를 보내야 하며 이런 서비스들의 효율성을 향상시키기 위해서는 멀티캐스트를 이용한 통신이 요구된다. 멀티캐스트 통신에서는 각 참여자들의 특성 에 따라 세션이 생성되며 생성된 세션들의 관리가 필요하다. 본 논문에서는 멀티캐스트 통신을 하기 위해 필요한 웹 기반의 세션 관리 프로토콜을 구현하였다. 추후에는 구현된 세션 관리 프로토콜인 SMP(Session Management Protocol)와 함께 세션의 참여자들을 관리하기 위한 프로토콜인 MMP(Membership Management Protocol)를 구현하고 이 세션과 참여자 관리 구조를 바탕으로 세션 전송 프로토콜인 GMP(Group Management Protocol)를 구현할 계획이다.

How to process event message traffic efficiently is important to collaboration among multiple distributed users, and it is a key research issue in the virtual environment fields. AOI model is one of solutions for this problem; which reduces message traffic by restricting event propagation region into an area in which a user is interested. However, in previous systems, it is difficult to adapt to dynamic environment where changes in the number and movement of participants are frequent. This paper proposes a new event management model, called extended AOI model, which is helpful to improve flexibility and efficiency of traditional models, and is able to extend its functions by introducing multi-layered regions. The proposed model can be applied to DVE and MMORPG as an event filtering model.

This study explores the moderating effects of economic stress in the relationship between organizational devotion and emotional self-sufficiency of the self-sufficient program participants. 698 persons who lived in Taegu participated in this study. Multiple regression analysis was adopted. Results indicate that higher level of organizational devotion is positively related to the higher self-sufficiency. In addition, economic stress moderated the effect of organizational devotion on emotional self-sufficiency. Practical implications of this study are two folds; One is that in order to increase emotional self-sufficiency, sense of community should be put into consideration; The other is that approach for decreasing economic stress should be included in the program for self-sufficiency. Overall, this study lays a groundwork for the self-sufficiency of the participants in the self-sufficient program.

In this study, the on-line discussion learning system of physics investigation was developed for developing the creativity in the problem solving and critical thinking. And with the number of participants of a topic unit, the formation of multiple discussion field and a turn-taking, we found that the interaction patterns of the students were composed of interpersonal interaction pattern, interaction pattern of one to one participation, interaction pattern of one to many participation and interaction pattern of many to many participation. These interaction patterns could make us understand the participation structure and the aspect of interaction of the students in the cyber space.

Previous researches on scalability problem of distributed virtual environment (DVE) have been mainly focused on spatial partitioning of area of interest (AOI). Congestion phenomena by avatar groups in AOI have been neglected relatively. However, AOI congestion is highly related to scalability of DVT because it exhausts system resources such as network bandwidth and rendering time, and could be a bar to perform collaboration among participants. In this paper, this will be defined as the problem that must be solved for the realization of the scalable DVE, and a model will be proposed to measure and control congestion situation in AOI. The purposes of the proposed model are to prevent high density of participants in AOI, and to protect stable collaboration in DVE. For evaluation of the performance it is compared with a previous method by defining the resource cost model which is dynamically activated to AOI congestion.

기존의 다중 사용자 지원 3차원 공간 정보에서의 가상 공간 관리 방식의 특징은 각 참여자에서 발생하는 이벤트를 중앙 서버에 전달해서 반영된 내용을 다시 각각의 참여자에게 전달하는 방식을 사용한다. 이러한 경우 가상 환경에 대한 상태 정보를 중앙 서버에서 관리하므로 및 일관성 유지가 용이하다는 장점이 있으나 네트워크에 과중한 부담을 주며, 확정성이 부족하다는 단점이 있다. 이 논문에서는 3차원 가상 환경에서 발생하는 이벤트의 형태를 아바타의 이동 이벤트와 그 밖의 이벤트로 구분하고, 가장 빈번히 발생하고 신뢰성이 비교적 적게 요구되는 아바타의 이동에 대한 이벤트 전달은 모빌에이전트간의 통신으로 전달함으로써 중앙서버의 부담을 줄여주며, 일관성을 효과적으로 유지할 수 있는 모빌 에이전트 기반 가상 공간 관리자를 설계하였다.

일반적으로 노동시장은 노동자와 고용주들로 구성되며, 이들은 복잡한 상호작용을 통해 노사관계를 형성한다 본 논문에서는 진화 에이전트들로 구성된 노동시장 모델 상에서 노동자들 또는 고용주들 사이에서 형성될 수 있는 전략적 연합을 적용하여 노동자와 고용주의 수적인 비율로 표현할 수 있는 직업밀집도와 직업집중도에 따른 행동 특성을 분석한다. 전략적 연합은 다중에이전트 환경에서 상호간의 이득을 보장하는 효과적인 방법이 될 수 있다. 진화 노동시장에서 노동자와 고용주들은 집단 내에서 자율적으로 연합을 형성하며 죄수의 딜레마게임으로 진행되는 거래에 참여한다. 실험결과, 에이전트들의 행동이 직업밀집도와 직업집중도에 따라 다르게 나타나며, 특히 전략적 연합이 허용될 경우 노동자와 고용주들이 보다 공격적인 형태로 노사거래에 참여함을 보여준다.

This study was conducted to analyze the effects of motivation and satisfaction with continuing education on the intention to participate in college continuing education programs among adult learners. and participation of continuing education to improve the quality of Continuing education programs operated by College and to develop diverse educational programs that reflect the needs of adult learners and increase their participation rate. This study analyzed data collected from 412 adult males and females taking courses at the Lifelong Education Center in four professional universities in Gyeonggi-do from May 1 to June 20, 2017. Data analysis was performed using SPSS Version 21.0 program, and general characteristics of the subjects were used. Descriptive statistics, t-tests and ANOVA were used to identify differences in participants' motivation, satisfaction with education, and intention to participate. Participants' motivation, satisfaction with education, and intention to participate were analyzed by Pearson's correlation. Participants were analyzed by stepwise multiple regression analysis. There was a significant positive correlation between motivation for participation in college continuing education programs, intention to participate in education programs, and intention to participate. The factors influencing participants' motivation for participation were participation motivation and education satisfaction 41.2%.The results of this study suggest that it is necessary to develop and operate a program considering the factors that can improve motivation for participation and educational satisfaction to increase learner motivation.
