Facebook become a powerful operator in the mobile advertising platform. Most of their income come from the mobile SNS advertising. Facebook’s 3rd Quarter 2015 earnings report boomed up New York stock market. It gives us an important implication about the effect of the mobile SNS advertising. The advertisements in the Facebook’s news feed sometime bother the users. Moreover, the ads will disturb the orderings of contents, and the mobile SNS users will be irritated because of frequent occurrence of irrelevant ads. The accurate ad targeting is the most important and critical factor in the mobile SNS advertisement. On the other side, minimizing the negative effects of the advertising avoidance factors is important. We developed a structural model that explain the relationship between the characteristics of SNS and advertising avoidance in the mobile SNS. We emphasized the technological interactivity variables like responsiveness, connectedness, and user control as an important exogenous independent variables. We also considered ubiquitous and personalization as an important independent variables. We placed the perceived risk and advertising value as mediating variables between them. The empirical tests proved the structural relationship in the model and all the model fitness indicator values were good enough. Of the independent variables, three variables(personalization, responsiveness, and connectedness) affected on perceived advertising value strongly and advertising avoidance indirectly. Two variables(ubiquitous and user control) affected on risk perception directly and advertising avoidance indirectly. The test results give us some important implications about user behaviors and perceptions in the mobile SNS advertisement. The best strategies are to minimize the user"s risk perception and to maximize advertizing value in the mobile SNS operation.

기술수용모델을 이용한 창업기업의 신규코인상장(ICO) 참여의사 분석
변정환(Jung-Hwan Byun),정대율(Dae-Youl Jeong) 한국창업학회 2018 한국창업학회 Conferences Vol.2018 No.2
본 연구는 창업기업의 신규코인상장(ICO) 참여에 대한 의사결정 요인에 대해 분석 한다. ICO는 암호화폐에 대한 폭발적 관심과 함께 블록체인 기술을 이용한 응용분야 로 크라우드펀딩과 같이 창업기업 초반에 온라인 플랫폼을 통해 불특정 다수를 대상 으로 투자자를 모집한다. 현재, 한국을 비롯한 중국 등 ICO를 금지하고 있는 국가도 있는 반면에 ICO를 새로운 사업분야로 육성하기 위한 스위스나 싱가포르 같이 적극 적으로 유치하고 장려하는 국가도 있다. 연구를 위한 첫 번째 단계로 ICO의 개념을 정의하고 창업기업의 자금조달 방법인 크라우드펀딩과 IPO간의 비교를 통해 유사점 을 찾는다. 그리고 ICO의 기업 참여수와 모금금액에 대한 통계자료와 함께 국가별 ICO 및 사업분류별 조사자료를 검토한다. 창업기업의 ICO 참여의사를 분석하기 위해 기술수용모델(Technology Acceptance Model)을 이용하고, 연구모형을 구축하기 위해서는 기존 연구결과를 토대로 기업정보 공개, 사회적 영향, 성과기대에 대한 요소를 검토한다. This study analyzes the determinants of Initial Coin Offering(ICO) participation in start-up entrepreneurship. ICO is an application area using block chaining technology with explosive interest in crypto-currency. It attracts investors to an unspecified number of people through an online platform like crowd funding at the beginning stage of a startup company. Currently, there are some countries that prohibit ICO, such as Korea and China, while some countries actively attract and encourage ICO such as Switzerland and Singapore to foster new business areas. And find similarities by comparing the funding methods of entrepreneurs with crowd funding and IPO. This study reviews business classification of ICO participants, along with statistical data on ICO fundraising. The Technology Acceptance Model(TAM) is used to analyze the entrepreneurial intention of the ICO. In order to construct a research model, this study examines the elements of corporate information disclosure, social impact, and performance expectation based on existing research results.

사회적기업의 비즈니스모델 특성과 기업성과간의 관계 연구
윤동주(Dong Ju Yoon),정대율(Dae Youl Jeong),조성의(Sung Eui Cho) 한국창업학회 2013 한국창업학회 Conferences Vol.2013 No.1
본 연구에서는 사회적기업의 비즈니스모렐특성과 기업성과 간에 어떠한 관계가 있는지를 파악해 보았다. 연구결과 비즈니스모웰을 구생하는 가치제안 요소언 목표고객, 가치제공볼과 가치창출 요소언 자원 및 핵섬역량, 내부 가치사슬, 외부 가치네트꿔크 그리고, 가치확보 요소인 수익모형, 비용구조, 성장원리, 혁신지향생 등의 활동이 사회적 기업의 사회쩍 성과와 경제적 성과에 영향을 주논 것으로 확인되었다, 연구의 컬과는 비즈니스포텔 특성이 사회적기업의 성과에 영향을 준다는 점에서 시사점을 갖는다. 즉 사회쩍 기엽은 비즈니스모델을 구체화하고 비즈니스모델을 실행하여 사회척, 경제적 성과를 창출해야한다. In this study, we know that there is relationship between the social enterprise businessmodel characteristics and corporate performance. From the result in this study, Businessmodel characteristics were identified as affecting the social performance and economic performance of social enterprise, the business model elements, target customers, provide valuable things as value proposition, resource and core competencies, internal value chain, external value networks as value creation, revenue model, cost structure, principles of growth, innovation orientation as securing value. From the results, has implications in terms of the business model characteristics will affect the performance of social enterprises. We will need to create social, and economic performance of social enterprise by running the business model and refine the business model.

The main goal of this research is at the development of a bundle product suggestion sub-system of an internet shopping mall for fishery products, which can reduce the search cost of user. To achieve the goal, we first study the key factors of successful direct commerce for fishery products, and second, we design a bundle product suggestion module and its sub-module. For this, we identify the objectives of system, and write out the necessary functions of the system and models(process model, data model, dynamic model) through the analysis of user requirements. Based on the functions and models, we design user interfaces, database, processes, and knowledge base. In designing knowledge base and inferencing strategy, we consider two intelligent agent approach (optimal algorithms, heuristic rules) and suggest one more approach (case-based reasoning). The intelligent agent can be used in enhancing the suggestion of multiple fishery product simultaneously. The system analysis and design documents presented as the research results can be used to provide good guidelines to the companies who consider developing an production suggestion agents.
