XML is the most common tool for data processing and data transmission in web applications. Policies are extensively used in all online business solutions and it is recognized that abinary decision such as 'yes/no' for access requests is not enough. In this paper, a method is developed to convert policy rules with provisions and obligations in logic formula formats into XML formats. The primary purpose is to enable security policy programmers to write flexible authorization policies in XML and to implement them easily. General syntaxes are defined to specify information for users, objects and actions in XML formats and an XML DTD is developed to specify authorization rules with these three components. To support various security features such as data transcoding and non-repudiation depending on data in addition to access control based on authorization policies, studies for specifying them in XML policy rules will be performed in the future.

This study aims to examine satisfaction of nursing students with online classes during first semester of 2020 after COVID-19 pandemic and the difference in satisfaction according to general and online-related characteristics. An online survey was conducted for all nursing students, and subsequently 627 responses were analyzed by t-test and ANOVA with SPSS WIN. Result reveals that students ability to use IT devices was above average, and most of them used laptop computers. Pre-recorded video lecture format was used the most, and improvement of online content was demanded the highest. Overall satisfaction with online classes was scored 3.0/5.0, with the highest satisfaction for anytime and anywhere learning, and the lowest satisfaction in recommending online classes to others. There were significant differences between self-evaluation on own grade, ability to use IT devices, format of online classes, and satisfaction about online classes. Through this study, it would be possible to suggest a plan to increase satisfaction of online class and basic data to establish university policy for online classes after COVID-19.

최근 대표적 글로벌 유통기업인 미국의 아마존과 중국의 알리바바가 전 세계적으로 가장 큰 시장점유가 있으며 두 기업의 국내진입 시 국내 유통산업에 큰 영향을 미칠 것으로 예상한다. 두 기업은 온라인 기업이 오프라인 기업을 흡수 합병함으로써 새로운 가치를 창출해내는 O2O (Online to Offline) 추세가 국제적으로 진행되고 있다. 아마존과 알리바바와 같은 글로벌 유통업체들은 일본, 인도와 같은 타 국가로의 세계 진출을 적극적으로 하는 추세이다. 본 연구에서는 아마존, 알리바바와 같은 글로벌 유통업체가 세계 진출의 일환으로 국내 유통시장 진입 시, 노출된 글로벌 경쟁 속에서 국내 유통기업들의 사업전망을 예측해보고, 해당 예측에 기반하여 기업 차원의 전략적 대응방안 및 정부 차원의 정책 지원방안을 마련하는 데 그 목적이 있다. 시장 현황분석을 기반으로 하여, 미래 시장예측 방법으로써 무작위로 추출된 난수(Random Number)를 이용하여 원하는 방정식의 값을 확률적으로 구하기 위한 알고리즘(Algorithm) 및 시뮬레이션(Simulation)의 방법인 몬테카를로(Monte Carlo, MC) 방법론을 사용하여 국내 유통시장의 변화를 예측하여 본 연구를 진행하였다.

This study aims to verify the mediating effect of mobile social participation on the relationship between the mobile device capability and life satisfaction. Using the data of 2018 Digital Divide Survey conducted by the National Information Society Agency(NIA), the mediating effect was verified by Baron & Kenny (1986)'s 3 step process, targeting 1,665 middle and older aged adults. The result is as follows: first, the mobile device capability of the middle and older aged people has a positive effect on life satisfaction. Second, the effect of the mobile device capability of middle and older aged people on life satisfaction is partially mediated by mobile social participation including expressing opinions on social concerns, proposing policies and filing a civil complaint, donation and volunteering work and online voting and responding to a poll. The result represents that the mobile device, such as a smart phone or a smart pad, capability of the middle and older aged group not only directly benefits the group but also helps expand their mobile social participation, which leads to, although indirectly, higher life satisfaction. Therefore, the study is expected to be a groundwork for a practical intervention for enlarging the use of mobile device and lifting digital information level of the elderly to encourage mobile social participation and drive life satisfaction.

An online community serves as a communication hub among members who desire to share their opinions and emotions. Thus, it is often utilized as a corporate or brand marketing tool. While focusing on commercial online communities from the marketing perspective, however, researchers have barely discussed non-commercial online communities despite its popularity. This study examined the influence of flow on satisfaction in the context of the non-commercial online community as well as the role of social capital as a significant mediator between flow and satisfaction. The result also included the differences between employed mothers and non-employed mothers. This study has expanded the research scope of online communities and offered theoretical and practical implications based on the interdisciplinary discussion that involves one of the understudied populations, mothers.

This study explores what factors influence college students' synchronous online learning satisfaction and what advantages and disadvantages exist when it comes to taking synchronous online learning courses. In-depth interview results suggest that advantages of synchronous online learning are convenience (no need for travel, no limitation for study place), saving money, and no worry for contracting Corona 19. However, disadvantages of synchronous online learning are instability of online learning system, lack of interaction between learners and educators, difficulty of instant communication, low education quality, and unfairness of exams. This study found that college students taking synchronous online course think that synchronous online learning is more appropriate for theory-based course than practice-based courses in that theory-based courses are lecture-oriented while practice-based courses require interactivity between learners and educators. This study provides educators a baseline understanding on how college students think over synchronous online learning and how to enhance students' satisfaction with synchronous online learning.

This study is a descriptive research study to verify the relationship between university students' learning flow, self-directed learning, learning outcomes, and online class satisfaction, and to identify factors that influence online class satisfaction. There was a significant positive correlation between university students' learning flow, self-directed learning, learning outcomes, and online class satisfaction. Online class satisfaction had a positive effect on learning flow and learning outcomes, but self-directed learning had no direct effect. The explanatory power of online class satisfaction was 49%. Based on the above results, in order to increase online class satisfaction, a plan is needed to improve university students' learning flow and learning outcomes for online classes. In addition, instructor and university are required to actively endeavor and support to improve the quality of online classes.
