A microblog is a service typically offered by online social networks, such as Twitter and Facebook. From the perspective of information dissemination, we define the concept behind a spreading matrix. A new WeiboRank algorithm for identification of key nodes in microblog networks is proposed, taking into account parameters such as a user's direct appeal, a user's influence region, and a user's global influence power. To investigate how measures for ranking influential users in a network correlate, we compare the relative influence ranks of the top 20 microblog users of a university network. The proposed algorithm is compared with other algorithms - PageRank, Betweeness Centrality, Closeness Centrality, Out-degree - using a new tweets propagation model - the Ignorants-Spreaders-Rejecters model. Comparison results show that key nodes obtained from the WeiboRank algorithm have a wider transmission range and better influence.

최근 SNS 사용자가 증가함에 따라 정부부처의 홍보에도 SNS가 주요 홍보채널로 등장하였다. 특히 리스크를 관리하는 데 있어서 SNS는 유용한 도구이자 새로운 도전 과제가 되었다. 우리나라에서 원자력은 주요한 리스크 중 하나이며, 원자력 규제기관이 국민과 어떻게 소통하고 있는가는 원자력시설에 대한 신뢰 혹은 수용성에 매우 주요한 영향을 미칠 수 있다. 이를 반영하여 본 연구는 한국(NSSC)과 미국(NRC) 양국의 원자력규제를 담당하는 정부부처의 SNS 활용과 수용자 반응을 비교 분석했다. 연구 결과, 양 기관 모두 '정보제공'목적의 포스팅이 가장 많았으며, PR유형의 경우 한국은 '관계관리 PR', 미국은 '이미지 PR'의 포스팅이 많았다. 수용자 반응을 살펴보면 참여형과 비주얼형(동영상, 카드뉴스, 인포그래픽 등)의 포스팅에 수용자들의 반응이 높았으며, 관계관리 PR에 대한 수용자 반응이 더욱 높았다. 이러한 연구 결과가 향후 정부부처 정책을 소통 전략을 수립하는데 있어 도움이 되길 기대해 본다.

The proliferation of social media has given rise to the new consumer group, namely, social consumers. This study identified the distinct characteristics of social consumers (i.e., online social search, online social navigation, online social connection) and examined the impacts of social consumer attributes on the engagement with fashion brands via brands' SNSs (BSNSs). A sample of 141 U.S. consumers who had browsed and/or participated in a fashion brand's BSNS (i.e., the Facebook page for fashion brands) was used to examine hypothesized relationships. The analyses involved running a confirmatory factor analysis and a structural equation modeling. The result indicates that the impacts of the social consumer attributes on the benefits of BSNSs (i.e., experiential and functional benefits) as perceived by consumers were significant, except the link between online social connection and functional benefits. In addition, consumers' existing relationship with a brand served as a moderating variable, strengthening the impacts of social consumer attributes on BSNS benefits. The perceived benefits of BSNSs positively affected perceived relationship investment which in turn influenced brand loyalty. Practical marketing suggestions are provided for fashion brands.

This study aims to determine the factors impacting customer loyalty of Saigon Co.op supermarket in Vietnam. Research design, data and methodology: this study applied the multiple regression analysis with 250 samples collected from Saigon Co.op customers. The questionnaire is provided to respondents via Google Form, and the link is sent to the fan page of Co.op mart on Facebook. Two hundred eighty-seven samples were collected, but 37 samples were removed due to missing values. Exploratory Factor Analysis (EFA) and regression analysis are used for data analysis on SPSS software version 20. Results: The findings show all four determinants of Saigon Co.op's customer loyalty, including Product Quality, Brand Image, Price Strategy and Service Quality.

우리나라 정부부처 및 공공기관에서는 매우 많은 양의 전자기록물을 생산하고 있는데, 그 종류도 다양하다. 또한, 이질적인 전자기록물이 결합하여 하나의 전자기록물을 이루기도 하는데, 이 논문에서는 이를 복합전자기록물이라고 부른다. 복합전자기록물의 대표적인 예로는 소셜 네트워크 서비스(Social Network Service) 기록물이 있다. 현재, 우리나라 대부분의 정부부처에서는 페이스북을 이용하여 각 정부부처의 정책 공지 및 국민의견을 수렴하는 등 그 활용도와 가치가 높다. 이 외에도 많은 복합전자기록물이 우리나라 정부부처로부터 생산 및 활용되고 있는 실정이나, 이들에 대한 보존 방안이 제대로 마련되어 있지 않아 많은 정보가 유실되거나 방치되고 있다. 이 논문에서는 현재 우리나라 정부부처에서 생산 및 유통되는 복합전자기록물의 종류 및 특성을 살펴보고, 복합전자기록물 보존 관련연구를 조사 분석한 뒤 장기보존 전략을 제안한다.

Social network services can be defined as an individual web page which enables online, human-relationship building by collecting useful information and sharing it with specific or unspecific people. Recently, as the social network services(SNS) such as Twitter and Facebook have been paid attention in many fields of the society. SNSs are also one of the fastest channels to get news which people may not be able to see on TV or newspaper. The number of people who feel they are benefiting from social network services are increasing dramatically. A number of researches about SNS are underway. The study based on the Technology Acceptance Model empirically investigates the relationship between characteristics of SNS (system, service, information, and emotional) and user satisfaction of SNS. The study also analyzes how the relationshipa between SNS characteristics, satisfaction and user acceptance are moderated by country type of SNS users and inclination toward SNS acceptance. To achieve these research purposes, the study conducted various statistical analyses using questionnaire of the Korean and Chinese SNS users. The results of the study are followings. First, SNS characteristics have a positive effect to the user satisfaction. Second, SNS satisfaction have a positive effect to the user acceptance. Third, the relationship between SNS characteristics and user satisfaction is moderated by the country type of SNS users and inclination toward SNS acceptance. The study results could provide some implications to researchers who have interest in studying SNS, also could help business managers to operate and develop their SNS site more effectively.

이 연구는 상품을 알리는 마케팅 측면에서 유용한 수단인 소셜미디어와 소비자를 설득하는 커뮤니케이션 측면에서 유용한 수단인 게이미피케이션 기법을 결합한 새로운 마케팅 트렌드를 심도 있게 살펴보고자 한다. 게이미피케이션은 오래전부터 다양한 분야에서 활용된 기법이나 고전적 게이미피케이션 기법과 소셜미디어 상에서의 게이미피케이션 기법에는 차이가 존재한다. 따라서 소셜미디어와 게이미피케이션에 대한 이론적 고찰을 바탕으로 소셜미디어와 게이미피케이션의 결합 현상의 배경과 특징을 살펴보았다. 그리고 게이미피케이션을 활용한 소셜미디어 마케팅 사례분석을 통해 사용자의 마케팅 참여 정도와 방법에 따라 일반참여형, 주도적 참여형, 창조행위형, 관계형, 체험형으로 기업의 마케팅을 유형화했다. 이를 통해 소셜미디어와 게이미피케이션이 결합할 때 나타나는 변화양상을 고전적 게임기법과 비교하였는데, 경쟁-성취-관계가 오늘날의 소비자에게 좀 더 유의미한 영향을 주는 요인으로 파악되었다. 이 연구는 게이미피케이션을 활용한 소셜미디어 마케팅의 변화된 게임기법을 연구하여 마케팅 전략에 도움이 되는 기반을 마련했다는 점에 의의가 있다.
