According to the US market research firm "Strategy Analytics(SA)", there is a sudden change of wind blowing in the global smart-phone market. In particular, several Chinese firms such as Huawei, Xiaomi and Oppo show a rapid growth in the pace of Chinese market, whereas other leading players like Apple and Samsung has slowly grown in China market. Therefore, this study will investigate the main antecedents of repurchase intention of smart phones in post-90th generation in China. In addition to this, the mediating effect of SIC will be analyzed. The results of the study are as follows; first, there is significant relationships among brand, individual experience and repurchase intention, on the other hand, there is no significant relationships between design, price, function factor and repurchase intention; second, SIC partially mediate the relationship between brand factors and repurchase intention. Based on the results targeted to post 90th generation in China, several implications are suggested for smart phone firms.

In this study, the behavioral model of Andersen and Newman(1973) was applied to identify the factors influencing the use of senior centers by the elderly in the community, and the mediating effect of user satisfaction was improved to improve the satisfaction of seniors using the Senior Center and operate the Senior Center. This study attempted to suggest policy and practical alternatives for activation. The subjects were 578 elderly people using 2,283 senior centers in Busan. As a result, the factors influencing the total usage period of the Senior Center were analyzed by age and type of potential factors among the leading factors, and the factors affecting the total number of days of senior center usage during the week were gender, age, and education level among the preceding factors. Appeared. Factors affecting user satisfaction as a parameter were analyzed as subjective health status among gender, age, and desire factors among preceding factors. As a result of verification of mediating effect of user satisfaction, there was a partial mediating effect between age and total use of Senior Center, full mediating effect between gender and days of Senior Center use, and partial mediating effect between age and Senior Center use days. Analyzed. According to the purpose and main findings of the study, the policy and practical suggestions for activating the satisfaction and use of Senior Center are as follows. First, program development and support according to the characteristics of senior center users are required. Second, there is a need to characterize per-path according to senior center type and regional environment. Third, there is a need to improve and raise the support standards for senior center operating expenses.

본 연구는 국내 제조업체를 대상으로 하여, 공급업체 선택기준 요인으로서 원가 요인과 유연성 요인의 적합성을 검증하고, 그들이 공급사슬 성과에 유의한 영향을 미치는가를 확인하는 것을 첫 번째 목표로 한다. 나아가 IT 중 POS, EDI, ERP의 기술들이 그 과정에서 조정적(moderate) 효과를 나타내는가를 실증적으로 검증하고자 한다. 전국에 소재한 제조업체를 표본조사하고 조정적 회귀분석의 방법에 의하여 검증한 결과, 유연성 요인은 공급사슬 성과에 유의한 영향을 미치고 있으며, IT 기술들의 조정효과는 매우 낮은 것으로 나타났다. 이러한 결과는 IT 투자의 '생산성 역설'과 관련이 있는 것으로 볼 수 있다.

표본의 크기의 제1종오류의 확률 $\alpha$, 실용적으로 차이가 있다고 판독되어서 검출하고자하는 요인효과의 오차에 대한 상대적인 크기, 그 값에서의 제2종오류의 확률 $\beta$에 따라서 결정된다. 이 논문에서, 우리는 고정요인과 랜덤요인이 포함된 실험계획에서 표본의 크기를 결정하는 방법을 간단한 MATLAB 프로그램을 사용하여 고려한다. 분할법과 지분요인배치법의 예제를 들어 유의수준 $\alpha$와 최소 표준과 검출효과 $\Delta^*$에서 검정력이 적어도 $1-\beta$를 갖도록 표본의 크기를 결정한다

With constant relaxation of regulations by the government in the 4th industrial innovation era, it has brought huge changes to the education environment as it has created solutions to hindrance factors against introduction of the cloud. Universities are getting more interested in the introduction of the cloud Computing but they still remain at the level of recognition diffusion and creating ambience. The study has analyzed empirical factors of the effect of introduction of the successful case "K Cyber University's Construction of Cloud-Based Remote Education System" through the previous studies on trait factors affecting the introduction of the cloud computing and the analysis of factors in terms of expandability, agility, compatibility, economic feasibility, security, stability and institutional support. Factors drawn through this are meaningful for empirical studies on presenting strategies and the directivity to introduce the cloud computing successfully. This study can be used as the background for further studies which will require various factors prior to introducing the cloud computing.

This study aims to develop the scale for business effectiveness targeting microcredit users. For this, based on domestic preceding researchers empirically handling the microcredit and also focus group interviews with users and specialists, total 30 preliminary questions were composed. After that, conducting the exploratory factor analysis targeting 127 finally collected surveys, in the results of analysis, the scale validity of three factors and 24 questions was verified. Also, considering the goodness-of-fit of model through the confirmatory factor analysis, the effectiveness scale of microcredit business was determined. The concrete factors included 5 questions of the store operation, 3 questions of business start-up satisfaction, and 16 questions of management competency. Lastly, based on the effectiveness scale of business developed by this study, the research direction and the practical development direction of microcredit was suggested.
