The purpose of this study was to evaluate the communication enhancement program through Social Network Service(SNS) of older adults in the community. This program was mainly designed for improving self-efficacy of older adults and enhancing their communication in the community by using SNS. This program was composed of several sub-programs; understanding the value of communication, meeting with SNS users, SNS education and practice, having activities with SNS, promoting SNS, holding public rehearsals and starting ceremony, and having off-line meeting. This study applied analytical framework based on logic model of systems theory, collected data from the subject group, and evaluated the sub-programs on dimensions of process and outcome. The results showed that this program has an effect on improving self-efficacy through participating SNS activities, enhancing communication through boosting SNS, creating new culture for older adults, and changing attitudes between generations. Based on these results, the practical guidelines for expanding the communication enhancement program through SNS, leading by older adults in the community, were suggested.

본 논문에서는 소비자들의 4차 산업혁명에 대한 인식이 어떠한지를 살펴보고, 그러한 인식들은 개별 소비주체들의 SNS 지향적인 활동에 따라 다를 것이라는 가정을 두고 분석을 시작하였다. 즉, SNS 지향적인 활동을 하는 사람일수록 4차 산업혁명에 대한 인식이 잘 되어 있을 것이다. 하지만 그러한 개방적인 인식도 프라이버시의 수준에 따라 의존적일 수 있을 것이므로 이에 대한 조절효과를 살펴보고자 하였다. 그 결과, SNS 지향적인 소비자일수록 4차 산업혁명에 대한 인식이 높게 나타났으며 이러한 관계는 개인들이 프라이버시에 대해 자유로울수록 더 증폭되는 것으로 나타났다. 본 연구는 4차 산업혁명에 당면한 경제구조 속에서 보다 적극적인 대응을 하기 위한 기초자료로 기여를 할 것으로 판단된다.

In this study, we classified SNS into open and closed types, and empirically examined in which SNS activity the privacy paradox holds. The idea comes from the argument that privacy paradox may be observed differently in the open SNS, which is more vulnerable to the leakage of personal information due to public profiles, and the closed SNS, which is relatively less vulnerable by limiting the range of acquaintances, The results of the empirical analysis are as follows. First, in case of SNS usage, the privacy paradox holds in the overall SNS activities, but different conclusions are drawn according to open and closed SNS. In particular, it is found that as privacy concerns increase, individuals respond in a reasonable and desirable way to reduce SNS activity in the open SNS, which is more susceptible to infringement. Second, in the case of SNS activity intensity, (i) heavy users are more seriously aware of the probability of privacy infringement than light users, so there is a reasonable response to reducing the intensive margin with increasing privacy concerns, and (ii) this tendency is more clearly observed in open SNS, which is more vulnerable to privacy infringement. Accordingly, insisting that the privacy paradox is empirically established by observing only the overall SNS activities without distinguishing them into open and closed SNS may be interpreted as a "Fallacy of Composition."

This study conducted a questionnaire survey on SNS users who are conducting K-POP record collection activities using SNS and verified factors affecting the intention to continue K-POP record collection activities. The main methods of analysis were exploratory factor analysis, confirmatory factor analysis, correlation analysis, and path analysis using SPSS 21.0 program and AMOS 21.0 program. The results are summarized as follows. First, compatibility for K-POP record collection activities through SNS has a positive effect on perceived usefulness, and observability also has a positive effect on perceived usefulness and perceived ease of use. Second, perceived ease of use for K-POP records collection using SNS has a positive effect on perceived usefulness. Third, perceived usefulness and perceived ease of use for K-POP records collection using SNS have a positive effect on continuous intention of K-POP records collection activity through SNS. As a result of this study, it suggests that the intention to continue the collection activities of K-POP records using SNS can be explained through the integration of innovation diffusion theory and technology acceptance model.

The purpose of this study was to examine major motivations for using SNSs and the effect of them on SNS participation. In order to address the research questions, 253 undergraduate and graduate students participated. Results of the study were summarized as follows. First, Cyworld was mainly used followed by Facebook and Twitter. Most of the respondents had access to SNSs via smart devices. The average frequency of SNS use was 1-3 times a day and they used them less than 30 minutes a time. The reasons why they started to use SNSs were mainly to follow current trends, maintain friendship, and accept acquaintances recommendations. Second, the result of component analysis derived four primarily underlying dimensions related to SNS use; self-satisfaction, social interaction, recreation, and information seeking. Third, both self-satisfaction and social interaction motivation had significant correlation with SNS participation. The results of multiple regression analysis showed that self motivation was more influential on active participation than social interaction and information seeking motivation.

최근 소셜 네트워크 서비스 시장이 급속히 성장함에 따라 SNS 사용자 또한 지속적으로 증가하고 있다. 그러나, 광고성 게시물도 함께 증가함에 따라 해시태그 기반 검색의 정확도가 감소하는 문제점을 가지고 있다. 본 연구에서는 SNS 검색 활동의 정확도와 효율성을 개선하기 위하여 SNS 해시태그 기반 재검색 시스템을 제안한다. 제안 시스템을 적용하면 SNS 사용자의 검색 활동의 정확도와 효율성이 증가할 것으로 기대된다.

This study aims to prevent the serious threat from dangerous person or group by responding or blocking or separating illegal activities by use of SNA: Social Network Analysis. SNA enables to identify the complex social relation of suspect and individuals in order to enhance the effectiveness and efficiency of investigation. SNS has rapidly developed and expanded without restriction of physical distance and geo-location for making new relation among people and sharing large amount of information. As rise of SNS(facebook and twitter) related crimes, terrorist group 'ISIS' has used their website for promotion of their activity and recruitment. The use of SNS costs relatively lower than other methods to achieve their goals so it has been widely used by terrorist groups. Since it has a significant ripple effect, it is imperative to stop their activity. Therefore, this study precisely describes criminal and terrorist activities on SNS and demonstrates how effectively detect, block and respond against their activities. Further study is also suggested.

Recent rise of social media channel is changing social and economic paradigm and is being used as an effective communication in marketing. The following research analyzes the most employed social marketing tools such as portal advertisement, blogs, and SNS channels to effectively execute social media marketing from performance indicator and ICSI perspective, analyzes each channel's characteristics and results based on Korea distribution companies' case studies and suggests a framework to effectively use each channel. Portal site advertisements are the most effective channel to draw customers with new information and are thus linked to profit by corporations with excessive budget and workforce. Blogs target a specific range of customers providing quality information and knowledge thus improving a corporation's and its product's trustworthiness, spread the word by allowing customers to scrap the information, form social groups and synthesize ideas, events, new contents and social involvement with loyal customers. SNS channels allow customers to get involved in real time information and events, grow through network by the power of customers, react immediately to customers' needs, and execute real-time market and customer reports. Though national corporations currently rely heavily on portal site advertisements, insightful marketing professionals are showing financial results with blog and SNS. In the future, based on a precise understanding of each channel's benefits and expected results, and with a focus on flexibility, timeliness and integrated use of each channel, a portfolio of dynamic marketing as a maximizing strategy could be synthesized.
