The purpose of this study is to examine the effect of Web site usability on trust, satisfaction, and repurchase intention in Internet shopping malls. The Web site usability construct consists of the factors such as contents, ease of use, navigation, and interactivity. In order to accomplish the purpose of this study, a research model was established and it suggests that the Web site usability, through the mediation of trust and satisfaction, eventually affect the repurchase intention of online customers in Internet shopping malls. The results of the study show that Web site usability has statistically significant effect on the repurchase intention of online customers and this effect is mediated by satisfaction. This research confirms the importance of usability construct in designing Web sites and understanding the use of Web sites. Implications of these findings are discussed for researchers and practitioners.

Increasing rate of late or deferred marriage in our society may have been inferred from alleged contribution of media use on people's idealistic expectations about marriage. This study examined the relationship between Korean-Chinese romance drama viewing and various sub-concepts of idealistic fantasy about marriage. Results from survey analysis indicate that although romance drama viewing has a positive association with life satisfaction, it was positively associated with various aspects of idealistic marriage fantasy (i.e., less materialism in marriage, more belief in love at first sight, and more unrealistic expectations on marriage). Further, differential cultivation effects of Korea and Chinese romance dramas were discussed.

본 연구는 기술수용모델(Technology Acceptance Model)을 기반으로 <클림트 인사이드(2017)>전시에서 사용된 <스토클렛 저택의 장식벽화(Stoclet Frieze)> VR 앱에 대한 인지된 유용성(이하 PU)과 인지된 이용용이성(이하 PEOU)의 평가에 초점을 맞추었다. VR 앱의 학습적합성(SFL)이 감상적합성(SFA)보다 높게 평가된 PU의 경우, 학습유용성(UFL)과 감상유용성(UFA)의 모든 요인이 만족도(DOS)에 긍정적인 영향을 미침으로써, 전시환경에서의 VR 앱의 학습에 대한 내적 동기 부여 및 감상 지원에 대한 잠재력이 확인되었다. 또한 PEOU의 모든 요인들은 DOS뿐만 아니라 DOI와도 유의미한 상관관계를 가졌다. 본 연구를 통해 TAM의 PU와 PEOU의 ATUA(DOS 및 DOI) 및 BITUA(ITRA(1) 및 ITRA(2))에 대한 영향력이 검증됨에 따라, 두 변수는 사용자의 VR 앱에 대한 기술 수용에 대한 예측을 가능케 했으며, 결론적으로 예술작품 원작을 재매개한 VR 앱에 대한 평가모델로써 TAM의 적합성이 입증되었다.

In recent years, activities have become more important in political activities and participation in policies. Therefore, the level of digital informatization can affect the participation in policy in the online environment. In this study, we examined how the policy activities of the disabled have a relationship with the informatization level. To this end, we analyzed the relationship between the level of digital informatization and the level of satisfaction with policy activities based on the results of the digital divide survey of 2017. The results of this study are as follows: First, it shows that the disabled people have a positive relationship with the digital access and policy activity satisfaction levels such as the possession of wired / wireless information devices and Internet accessibility. Second, it is found that digital information capacity level and income level such as PC utilization ability and mobile digital device utilization ability have a positive (+) relationship. Third, as the level of digital information utilization such as wired and mobile Internet usage increased, the level of satisfaction with policy activities also increased positively. This suggests that the government needs various information policy to increase the level of digital informatization of the disabled.

TMN에 기초한 망 관리 시스템은 관리자/관리대행자 패러다임으로 역할이 분류되며 관리자는 관리대행자를 통해 관리 객체의 집합체인 관리정보베이스(MIB)에 접근할수 있다. CMIP 질의는 관리 정보 트리 상에서 관리 행위가 이루어질 관리객체를 선별하기 위하여 Scope 와 Filter를 이용한다. 본 논문에서는 관계형 데이터베이스를 이용하여 관리 정보베이스를 구축시 이러한 질의를 한번의 데이터 베이스 스캔으로 처리할 수 있도록 관리 객체의 " Distinguished Name"을 이용하여 MIT를 형성하고 SQL의 LIKE 연산자를 이용하여 Scope를 만족하는 노드를 찾는 방안을 제시한다. 이러한 방법은 부모자식 관계를 이용하여MIT를 표현하고자 결합 연산에 의해 Scope를 처리하는 일반적인 방법에비하여 성능이 우수함을 보였다. 관리자와 관리 대행자간의 교신을 위하여 IODE 8.0 CMIP프로토콜 스택을 이용하였고 ASN.1인코딩을 위하여 Pepsy컴파일러를 사용하였다.일러를 사용하였다.

Domestic delivery app services are taking a leap forward as the non-face-to-face culture spreads due to the COVID 19 situation and the industrial scale is also growing. In the expanding delivery app service market, we try to verify the structural relationship between variables by empirically analyzing the influencing factors of users' trust in rational and emotional factors. Delivery app service users trust and discriminate parameters in the relationship between rational and emotional factors. Satisfaction according to the trust of a valid delivery app service and service expansion model through word of mouth was designed. It was verified through a hypothesis whether it had an effect, and it can be used as a variety of service strategies for delivery app service users.

Our society is evolving into an aging society. The purpose of this study is to investigate how digital informatization capacity of elderly people, one of the so - called information - neglected people, affects social activities. To this end, we analyzed the relationship between digital informatization level and social activity satisfaction level of old elderly people based on the results of the digital information gap survey in 2017. As a result, it was found that there was a positive relationship between digital access and satisfaction level of social activities, such as whether elderly people have wired / wireless information devices and internet accessibility. Second, it was found that digital information capacity level such as PC usage ability and mobile digital device utilization ability had a positive (+) relationship with only social activities. Third, the level of satisfaction with social activities increased as the level of digital information utilization increased, such as whether they were using wired and mobile Internet. This suggests that the government needs a policy to resolve various information gaps that can enhance the level of digital informatization of elderly people.

As the digital informatization society deepens, the digital divide of the information - underprivileged becomes increasingly serious social problem. In this study, we analyzed the relationship between digital informatization capacity and satisfaction level of leisure activity in low - income class. For the analysis, we analyzed the relationship between digital informatization level and leisure satisfaction level of the low income class based on the results of the digital information gap survey in 2017. As a result, it was found that there was a positive relationship between digital access and leisure activity satisfaction, such as having a wired / wireless information device at low socioeconomic level and availability of Internet access at all times. Second, digital information capacity level and leisure satisfaction level such as PC usage ability and mobile digital device utilization ability have positive (+) relationship. Third, the level of digital information utilization, such as the use of fixed and mobile Internet, also showed a positive (+) relationship with the leisure satisfaction level of the low income class. This suggests that it is necessary to provide various supports to resolve the digital divide between the low income class and the general public.
