E-Learning is another way of teaching and learning. E-learning is a networked phenomenon allowing for instant revisions and distribution, and goes beyond training and instruction to the delivery of information and tools to improve performance. The benefits of e-learning are many, including cost-effectiveness, enhanced responsiveness to change, consistency, timely content, flexible accessibility, and providing customer value. The proponents of e-learning stress the importance of using communities of interest to support and enhance the learning process. They also emphasizes that people learn more effectively when they interact and are involved with other people participating in similar endeavors.The purpose of this research is to identify the determinants of attitude in graduateprograms operated only on e-learning basis. This study developed a research model toanalyze the factors explaining the satisfaction level from classes, employing userconvenience, multimedia-quality, interactivity, and flow as major research variables, and collected 439 survey responses from graduate students attending the classes.ㄴr graduate To ensure the content validity of the scales, validated items adapted from prior studies were used to measure the satisfaction level from classes, user convenience, multimediaquality,interactivity, and flow. The respondents indicated their agreement or disagreement with the survey instruments using a five-point Likert-type scale. We also measured demographic variables such as gender, income, education, and organization position.The hypothesized relationships were tested using the structural equation model. Even the goodness-of-fit index, GFI and RMSEA failed to meet the recommended minimum level, these were close enough to suggest that the model fit was reasonably adequate to assess the results for the structural model. Other goodness-of-fit indices were found to exceed the recommended level.The statistical results indicate that the flow influences the satisfaction level, and that interactivity between students and professors has some impact on the flow, but the interactivity among students did not appear to be significant to the level of satisfaction. It was also found that, contrary to our expectation, only the user convenience influences the level of interactivity. The characteristics of the samples may give some partial explanationfor this surprising result. The respondents averaged more than 40 years in age, and had close to average 15 years of work experience, preferring text-based contents tomultimedia-based ones. They also normally study during weekends at home, which maydistract them from interacting among themselves.Within the context of arguing that the exploration of gender issues with respect to e-learning is important, this research also examines the gender differences in path coefficients. To this end, the structural model was tested with the data from entire data sample (i.e., women and men pooled together) and each of the subsamples (i.e., women taken separately and men taken separately). Properties of the causal paths, including standardized path coefficients, the significance of difference, in the hypothesized model, arealso presented, so that we can investigate the relative influences of different dominants,demonstrating how women and men differ in their decision-making processes regarding the flow and satisfaction from usage of e-learning. Some gender variation was found for some path coefficient. This results revealed that men's perception of user convenience was the more significantly direct and more salient than women's in determining the level of interactions between the students and contents.Although multimedia quality was not considered an important direct determinant ofinteraction level in total, it was significant for men compared with women. This finding suggests that pedagogical principles, including principles of developing and packaging content, could be employed in the development and

On-line game business has emerged as the most lucrative entertainment industry, with over 4 million players in China, with more than 45% 0f the market dominated by Korean on-line games. While the interactive entertainment market continues to expand, with many new Korean on-line game publishers entering the market, relatively little is known about which factors influence online game players' behavioral intentions (i.e., intention to play, brand-identity, word of mouth, flow, etc.) in this area. It appears that in this extremely attractive and growing services segment, academics, as well as practitioners, would benefit from investigating the relationships among the players' intention to play, social norms, word of mouth, flow, and the impacts of several other key game-related constructs. A conceptual framework is proposed and a simultaneous equation model is developed. This paper develops the exploratory LISREL model for identifying the factors affecting the players' intention to play for on-line games. Based on data collected from on-line questionnaire survey in China, the validity of the model has been tested and interesting conclusions have been developed concerning the relationships between the game-related constructs. It is hoped that this result might provide the useful guidelines for developing the successful on-line game contents. With better understanding of the players' behavioral intentions, Korean on-line game developers should be able to penetrate the China market with sustainable advantage over their competition.

최근 다양한 기후변동성으로 인해 전 세계적으로 극한호우사상이 동시다발적으로 일어나고 있다. 우리나라의 극한호우사상은 주로 여름철 태풍으로 인한 호우와 국지성 집중호우에 의해서 발생한다. 극한호우사상에 대한 적절한 확률강우량을 추정하기 위해서, 본 연구에서는 연최대치일강우를 태풍으로 인한 강우와 집중호우로 인한 강우로 구분하여 확률적 거동을 고려하였다. 일반적인 강우빈도해석법은 연최대치강우가 단일 모집단을 이룬다고 가정하여 단일 분포함수를 적용하여 확률강우량을 추정하는 반면, 본 연구에서는 연최대치강우를 구성하는 두 가지 호우의 통계적 특성을 수문빈도해석에서 고려하기 위해, 혼합 분포함수를 적용하였다. 비교적 긴 관측강우자료를 보유한 15개 지점을 선정하여, 일강우량에 대한 확률강우량을 산정하고 비교분석을 실시하였다. 혼합 검벨분포모형에 의한 확률강우량은 단일 검벨분포함수를 적용한 확률강우량과 비교하여 지역에 따라 증감이 나타났으며, 이러한 결과는 홍수방어시스템의 계획 및 설계에서 유용한 정보를 제공할 것이다. Recently, due to various climate variabilities, extreme rainfall events have been occurring all over the world. Extreme rainfall events in Korea mainly result from the summer typhoon storms and the localized convective storms. In order to estimate appropriate quantiles for extreme rainfall, this study considered the probability behavior of daily rainfall from the typhoons and the convective storms which compose the annual maximum rainfalls (AMRs). The conventional rainfall frequency analysis estimates rainfall quantiles based on the assumption that the AMRs are extracted from an identified single population, whereas this study employed a mixed distribution function to incorporate the different statistical characteristics of two types of rainfalls into the hydrologic frequency analysis. Selecting 15 rainfall gauge stations where contain comparatively large number of measurements of daily rainfall, for various return periods, quantiles of daily rainfalls were estimated and analyzed in this study. The results indicate that the mixed Gumbel distribution locally results in significant gains and losses in quantiles. This would provide useful information in designing flood protection systems.

  The purpose of this research is to identify the determinants of loyalty in online games. This study developed a research model to analyze the factors explaining the loyalty level from gamers, employing social identification, flow, and positive anticipated emotion as major research variables, and collected 1308 survey responses from gamers. Within the context of arguing that the exploration of age range issues with respect to online games is important, this research also examines the age differences in path coefficients. To this end, the structural model was tested with the data from entire data sample (i.e., the age of 10s, 20s, and 30s pooled together) and each of the subsamples (i.e., teens taken separately, twenties taken separately, and thirties taken separately). Properties of the causal paths, including standardized path coefficients, the significance of difference, in the hypothesized model, are also presented, so that we can investigate the relative influences of different dominants, demonstrating how teens, twenties, and thirties differ in their decision-making processes regarding the flow, social identification and loyalty from online games.

본 연구는 인터넷 사용자를 대상으로 정보보호 활동을 유도할 수 있는 선행 요인들을 실증적으로 탐색하기 위하여 수행되었다. 본 연구에서 제시된 인과모형은 정보프라이버시에 대한 염려가 어떻게 자기 효능감과 인지된 유용성을 거처 정보보호 활동으로 이어질 수 있는가에 대한 것이다. 282개의 표본 데이 터를 이용하여 수행한 연구결과, 인터넷 사용자가 인지하는 정보프라이버시에 대한 염려는 자기효능감, 인지된 유용성, 그리고 정보보호 활동에 유의한 영향을 미치는 것으로 도출되었다. 또한 인지된 유용성 과 정보보호활동은 자기효능감에 의해 유의한 영향을 받는 것으로 나타났다. 그러나 예상과는 달리, 인 지된 유용성은 정보보호 활동에 통계적으로 유의한 영향력을 미치지 않았다. 본 연구의 결과는 온라인 기업과 인터넷 사용자들뿐만 아니라, 정보보호 교육을 제공하는 교육 관련자들에게 의미 있는 함의를 제 공할 것이다. This research aims to empirically explore the antecedents that could impact on internet users’ information protection behavior. 282 of sample data collected from internet users was used to test the hypotheses. The results of this research reveal that the internet users’ information privacy concerns has a significant impact on self-efficacy, perceived usefulness, and information protection behavior. In addition, we found that perceived usefulness and information protection behavior are significantly influenced by self-efficacy. However, contrary to expectations, perceived usefulness has no statistically significant effect on information protection behavior. These findings provide significant implications for online companies and internet uses as well as educational stakeholders that give educations about information protection.
