The purpose of the present study is to examine the structural relationship among academic stress, achievement motivation, learning environment, school flow and learning persistence in cyber education. For this study, 879 students who were enrolled in S cyber university in Korea was chosen to conduct the survey. Achievement motivation was measured in the beginning of the semester. Academic stress, learning environment, school flow, and learning persistence were measured at the end of the semester through the web survey system. The results of this study were as follows: First, academic stress, achievement motivation, and learning environment significantly affected school flow. Second, academic stress, achievement motivation, and school flow affected learning persistence, but didn't affect learning environment significantly. The results imply that academic stress, achievement motivation, and school flow should be considered as the significant elements for constructing cyber education environments to enhance students' learning persistence.

The purpose of this study is to explore the differentiated motivations of users of live commerce by focusing on the entry into untact consumption culture. In addition, we intend to verify the mediating effect of engagement in the relationship between the motivation and attitude of live commerce use. As for the research method, an online survey was conducted targeting live commerce users, and 245 valid samples were used for analysis. For data analysis, frequency analysis, exploratory factor analysis, reliability analysis, multiple regression analysis, and mediation regression analysis were performed. As a result of the analysis, the motivation for using live commerce was derived from four factors: Enjoyment of interaction, Substitutability of personal examination, Need for community, Trend setting. And Engagement was found to have a significant effect on attitude. Finally, engagement was found to have a partial mediating effect in the relationship between the motivation and attitude of live commerce use. The research results will provide implications for understanding non-face-to-face consumption culture and establishing effective strategies for the live commerce industry in the future.

This study is to investigate the causality of participation motivation, self-efficacy, self-respect and ceaseless participation intention of college students who joined mind growth program. Based on the outcome of previous studies, hypothesis and research model of this article was designed, and subjects of authentic analysis were 88 college students in mind growth program. The conclusion of this survey thru fitness levels of path model and analysis of covariance with hypothesis verification is as follows. The higher participation motivation of college students who joined mind growth program is, the higher self-efficacy and self-respect are getting. The higher participation motivation and self-efficacy thru self-respect are, the higher ceaseless participation intention is getting.

Recently, e-sports has been receiving social attention. Game leadership is a necessary skill to perform effective game tasks, and it is very important to e-sports game and improve teamwork. As a result, there is a need to identify psychosocial factor that promote game leadership. This study tried to examine how game motivation, game efficacy, and psychological factors(self-control, social intelligence, self-esteem) reported to have an important effect on leadership have relation with game leadership to MOBA genre users who were known to consider role of game leadership as important factor. We used data from 196 adolescents using MOBA games for surveys. As a result of analysis, internet game time, game efficacy, and social intelligence had a positive relationship with game leadership. And game motivation(social, exploration and escape) also had a positive effect on game leadership. But self-control, self-esteem and some game motivations(acquisition, achievement) was not significant.

This study aimed to examine the mediating roles of self-determined motivations on the effect of class climate perceived by middle school students on self-regulated learning ablility. For this purpose, a total of 589 students were selected as subjects in this research. Structural equation modeling was conducted so as to verify the relationship among all the variables. As a results, first, the perceived autonomous class climate had a direct effect on self-regulated learning ability and an indirect effect on self-regulated learning ability through the mediation effect of identified regulation. Second, the perceived controlled class climate had a direct effect on self-regulated learning ability and an indirect effect on self-regulated learning ability through the mediation effect of identified regulation, introjected regulation, and external regulation. This study implies that facilitating autonomous engagement in learning activities will be a effective educational intervention to improve self-regulated learning ability.

The purpose of this study was to obtain the basic data to enhance the career decision self-efficacy of undergraduates by investigating the variables affecting it by looking into the influence of career motivation and flourish of undergraduates. To achieve this, a survey research was conducted for the 355 undergraduates who were studying at the university in B-city with measuring tool of the career decision self-efficacy, the career motivation and the flourish. The result of this study was as follows; Firstly, there were significant positive correlations among career decision self-efficacy, career motivation and flourish. Secondly, it showed that there is a significant moderating effect of flourish in the relationship between career motivation and career decision self-efficacy in undergraduates. The results of this study suggest that career motivation and Floridians have a significant effect on career decision self-efficacy. It is suggested that career motivation and florish should be considered together to improve the career decision self-efficacy of college students and to enable them to carry out the career decision task successfully.

The purpose of this study is to identify the factors affecting marriage motivation in colleger and to provide basic data for the countermeasures for decrease in marriage rate. The subjects of this study were 175 colleger from K-do. Data were collected from October 1st to October 10th, 2018 and analyzed using IBM SPSS WIN/21.0 to get frequency, percentage, average, standard deviation, t-test, ANOVA, Pearson correlation coefficient, and Multiple regression. The subjects' view on marriage was 3.35 points, view on children was 3.11 points, psycosocial maturity was 2.99, social pre-parental role recognition was 3.46, and marriage motivation was 2.81. The marriage motivation of the subjects was positively correlated with view on marriage (r=.38, p<.001), view on children (r=.50, p<.001) and psychosocial maturity (r=0.25, p=.001), and psychosocial maturity was positively correlated with social pre-parental role. The most important factor that affects the subjects' marriage motivation is their view on children (${\beta}=.407$, p<.001), followed by view on marriage (${\beta}=.329$, p<001), Gender (${\beta}=-.184$, p=.004), psychosocial maturity (${\beta}=.159$, p=009), religion (${\beta}=.126$, p=.003). The explanatory power was 52.1% (F=26.01, p<001). Therefore, a program promoting the views on children and marriage to improve marriage motivation, a customized program considering gender and religio, and further research promoting marriage motivation is needed.

고속 무선통신에 적합한 OFDM 신호를 복조하기 위해서는 빠르고 정확한 심볼의 시작점을 찾는 것이 중요하다. 본 논문에서는 고속 무선 LAN에서 사용되는 Orthogonal Frequency Division Multiplexing (OFDM)시스템에서 훈련신호를 효율적으로 사용해서 심볼 동기를 검출하는 알고리즘을 제안한다. 제안된 알고리즘은 직교성이 뛰어난 PN 코드를 훈련신호로 사용하여 OFDM 심볼의 대략적 프레임 동기는 훈련 신호의 실수 부분을 최소오차 방식을 적용하고 정밀한 심볼동기는 주기가 짧은 PN 코드를 결합시켜 하나의 심볼을 만든 후 상관관계를 적용하여 검출하였다. 그 결과 제안된 알고리즘이 계산량을 현저하게 줄이면서 심볼 동기는 정확하게 검출함을 확인하였다.

QoS(Quality of Service)측면에서 멀티미디어 응용 서비스를 제공하기 위해서 멀티미디어 통신은 여러 가지 요구사항을 지원하여야 한다. 연속적으로 생성된 미디어의 시간적인 관계를 유지하면서 재생시킬 수 있는 동기화 메커니즘은 무엇보다도 중요한 문제이다. 전달되는 매체를 공동을 사용하기 때문에 트래픽의 폭주시, 지역적으로 멀리 떨어져 있는 경우에는 지연의 현상이 발생하게 된다. 본 논문에서는 지연에 의해 발생되는 지연지터에 대하여 완충역할을 할 수 있는 최소 버퍼크기를 제시하였다. 주문형멀티미디어서버(MOS)의 경우 각 미디어 별로 서버에 저장하여 서비스하는 연구가 현재 활발히 진행되고 있으며 이것은 네트워크의 부하를 줄일 수 있다는 장점을 가지고 있다. 또한 이러한 데이터의 경우 클라이언트에서 어느 정도 지터를 예상하여 버퍼의 크기를 갖고 있어야 하는 문제는 아직도 큰 문제점으로 나타나고 있다. 본 논문은 버퍼의 크기 및 재생에 관한 동기화 시점을 조정함으로서 버퍼의 오버플로우나 언더플로우의 현상을 방지하고자 한다. 제안한 기법은 기존의 기법보다 향상된 동기화 기법임을 시뮬레이션을 통해 검증하였다.
