The purpose of this study is to verify the extended technology readiness and acceptance model according to the characteristics of technology for the continuous use motive of SNS users. In particular, we conducted a comparative study on the differences in technology readiness and acceptance model between countries through the empirical analysis of the users of SNS in Korea and China with different technological and cultural environments. The results of this study are as follows; First, Positive technology readiness index has a positive effect on performance expectancy, effort expectancy, social influence, and facilitating conditions, which are variables of UTAUT. Positive technology readiness also has a positive effect on Enjoyment, which is added in this study. Second, negative technology readiness index has negative effect on performance expectancy and social influence, which are variables of UTAUT. In addition, negative technology readiness index has not a significant effect on enjoyment, which was added in this study. Finally, the relationship between technology readiness index, motivation for technology acceptance, and continuously intention to use has a partially different influence on the Korean and Chinese users. Based on the results of this study, this study suggested academic implications and practical implications.

본 연구는 정보 간의 관계에서 도출되는 특징을 적합하게 보여줄 수 있는 시각화를 위한 연구이다. 정보의 관계에 주목하는 이유는 관계 구조를 통해 정보의 성격과 특징을 파악할 수 있기 때문이며 이러한 정보의 관계는 사회연결망 분석을 통해서 파악할 수 있다. 이 연구에서는 사회연결망분석에서 관계의 성격을 도출하는데 중요한 지표로 다뤄지는 영향력의 시각화를 연구범위로 설정하고 첫째, 연결망 내에서 관계를 나타내는 요소와 영향력을 나타내는 지표를 분류하여 정리하였다. 둘째, 사회연결망에서 영향력을 나타내는 관계의 요소들 간의 연관을 살펴 영향력 시각화의 네트워크를 만들었다. 셋째, 사회연결망 분석과 시각화 프로세스와의 상호작용을 설명하는 영향력 시각화의 프레임워크를 제안하였다. 본 연구에서 제안하는 영향력 시각화의 네트워크와 프레임워크는 사회연결망의 영향력 요소를 이해하고, 분석하는데 유용하게 사용될 수 있을 뿐만 아니라 연결망의 시각화에 있어 합리적이고 효율적인 접근을 가능하게 함으로써 정보디자인에 있어 새로운 방법적 접근이 되리라고 기대한다.

스마트기기 대중화에 따른 소셜 네트워크 서비스의 폭발적인 증가로 온라인상의 관계와 활동이 오프라인상의 실생활까지 영향을 미침에 따라 온라인상의 소셜 네트워크 활동에 대한 관심과 중요성이 지속적으로 증가하고 있다. 본 연구에서는 SNS 활동에 영향을 미치는 요소를 대상(object, 사용자(User), 영향력 방향(Influence direction), 영향력 강도(Influence distance) 4가지 요소로 정의하고 SNS 사용자 상호간 영향을 유기적 관점에서 측정하는 방법을 제안하였다. 기존 영향력 측정 요소를 반응횟수, 친구의 수, 접촉횟수 등 정형 데이터와 원인시간과 반응시간의 차이, 호감도, 반응의 유형 등 비정형 데이터까지 확대하여 영향력 방향(Influence Directio)과 영향력 강도(Influence Strength or Distance)의 측정 기법을 정교화 하였다. 또한, 영향력 측정을 위한 data를 수집하고 분석하는 시스템과 facebook으로 수집한 sample data를 이용한 영향력 측정 기법 프로세스를 실험하고 구현 가능성을 설명하였다.

This study is about the influence of authors' centrality on research outcomes in a large-scale collaborative research network. Using the social network analysis method, five types of centralities were derived. Six research outcomes of individual researchers were also derived through bibliographic information of the social science field for the last 10 years. A multivariate regression analysis was conducted to examine the causal relationship between the centrality and research outcome, and the effect of centrality on research outcomes was found to be statistically significant. The result of this study shows that the revised citation and H-index significantly influenced the authors' centrality. This result can imply that the centrality of the researcher can expect a considerable influence of the thesis as well as a certain level of productivity. The meaning of this study is to analyze the effect of centrality on the research outcomes of the large-scale collaborative research network in the past decade, and is carefully to suggest a guideline in order to support new research information services for active researchers and the advancement of collaborative research. This study has its limitation for interpreting the diverse academic fields of the social sciences in a uniform way. In future study, it is necessary to conduct studies using various weighted indices for network centrality in order to measure the influence of research.

This study examines how economic preparation for later life directly influences life after retirement. As people's life cycle is gradually getting longer, preparation for the later time with less economic activity after retirement is becoming more important. Thus, this study analyzes the factors influencing life after retirement. Data comes from the Korean Retirement and Income Study (KReIS) surveyed carried out by the National Pension Research Institute in 2015. The analysis includes Cronbach's alpha, Pearson Product Moment Correlation Coefficient and Sobel Test. This study confirms that voluntary retirement has a positive influence on life satisfaction. Results are in line with previous research about the relationship between voluntary retirement and retired life. When a person retires voluntarily, financial preparation can be made in advance for retirement. In case of involuntary retirement, people may experience a sense of loss in personal standing and financial difficulties due to the unexpected situation. Especially, early retirement from the main workplace leads to unstable later life. The study's policy recommendation, in particular, calls on government and businesses to agree on social responsibility for helping employees to retire in the predictable retirement time and, thus, enabling the retiree to decide all aspects of the path after retirement.

The present study investigated the effect of area-specific social networks on urban workers life satisfaction. For this, 356 adults over age 20 were interviewed from June 17th 2013 to June 29th 2013. The findings are as follows: First, the closeness of family network index demonstrates that participants with higher affective support have higher life satisfaction. In addition, stronger extended family network brings more life satisfaction and so does a bigger friendship network. Secondly, the extended family network explains 17.6% of the variance in social networks follows by family network, other network, and friendship network, respectively. The closeness variable of social networks yields statistical significance on all categories of networks. The affective support level in the closeness variable of social networks shows differences as well; family network positively associates with life satisfaction. The purposes of this research are to investigate the actual conditions of urban workers' life satisfaction and the influence of family, extended family, friendship, and other variables on life satisfaction. If social networks have an influence on life satisfaction, to find the domain of social networks that holds the most influences on life satisfaction is an important ground in the process of implementing regional welfare.

This study aims to analyse the landscape ecological characteristics of 39 rural villages in Korea and classify them according to their characteristics. After producing a land-use map of rural villages, this study quantified the landscape ecological characteristics of the subject sites as 18 landscape indexes using Fragstats. By applying the landscape index as a variable, selecting 4 factor through principal component analysis and conducting a cluster analysis, it classified them into 3 groups. Rural villages of Korea have their unique types of land-use due to the influence of physical environment such as geography, climate and ecology as well as the social and cultural influence, and the characteristics of land-use can be analysed and classified using the landscape index, the quantified landscape ecological characteristics.

Objective: Participation restrictions are serious problems that stroke survivors experience while reintegrating into family, work, community, and social situations after participating in rehabilitation programs. The purpose of this study was to explore the factors affecting participation in activities of daily living (ADL), as well as social and leisure activities of individuals with hemiparetic stroke. Design: Cross-sectional study. Methods: The study involved 96 participants who were diagnosed with a first stroke 6 months before the study (58 men, 38 women; $60.3{\pm}14.3years$). The Berg Balance Scale, Modified Barthel Index, Manual Function test, and Activity Card Sort were used to assess static and dynamic balance function, upper limb function, level of independence, and their level of participation within the community. A regression analysis was used to identify the influence of factors affecting participation in ADL, social and recreational activities. Results: The Activity Card Sort scores were significantly affected by the Manual Function test and Modified Barthel Index scores (p<0.05). Participation in leisure activities was affected by the level of independence. Participation in social activities was affected by the balance function and level of independence of the participants. Conclusions: The results of this study have shown that participation restrictions are affected by upper limb function, balance function, and the level of independence in individuals with hemiparetic stroke.
