본 연구는 전략적 제휴와 연계를 추구하는 장기 지속적인 그린IT 전략의 필요성을 제시하였다. 그린IT 기업의 사회적 압력과 환경지향성과 환경매력도가 장기 지속적 그린IT 전략에 어떠한 영향을 미치는지, 장기 지속적 그린 IT 전략이 환경성과에 어떠한 영향을 미치는가를 알아보기 위한 연구모형을 설정하였다. 선행연구에서 종속변수로 사용되던 장기지속성을 본 논문에서는 매개변수로 설정하였다. 그린IT 기업을 대상으로 설문조사를 실시하였고, 통계패키지를 이용하여 실증적으로 분석하였다. 사회적 압력과 환경지향성과 환경매력도와 환경성과 사이의 관계에서 장기지속성이 매개효과가 있음을 검증하였다. TIn this paper, The need for a long-term sustainable Green IT strategy to pursue strategic partnerships and alliance was proposed. We made a research model to identify how social pressure, environmental orientation and environmental attractiveness affect into the Green IT strategy, and how Green IT strategy affects on Green IT company's environmental performance. In previous studies, the long-term persistence was used as the dependent variables, but in this paper it was used as a parameter variable. A survey of Green IT companies and a empirical analysis by statistical software package were conducted. It was verified that the mediating effect is between the social pressure, environmental orientation, environmental attractiveness and environmental performance by the long-term persistence.

Previous research on university life of Chinese students studying in Korea has been conducted on students in Korea, but Chinese students have a sense of belonging and university prejudice against Korean universities, so the objectivity of research is not clear. This paper conducted a survey of the Chinese people in China and conducted a media search for attracting foreign students. Not all foreign students are proficient in Korean language. Even students who have completed more than one year of education in the Korean language institutes or passed advanced level of Test of Proficiency in Korean(TOPIK) have difficulties in everyday life and acquiring a degree. According to the results of this study, until foreign students who lack sufficient Korean language skills are able to adapt to culture and acquire information in Korea, it is desirable to prepare multilingual content services so that they can obtain academic information or daily information necessary for studying in their native language.

As a result of the development of information and communication technology and the negative phenomenon of using smart devices including smart phones, many people are stressed. In this paper, we examine the effect of independent variables(mobile use ability, technical limit, speed of change, popularity) and control variables(manual service) on technostresses, which is derived from previous studies conducted from the negative viewpoint of existing information technology. For empirical analysis, empirical data were collected from a total of 206 individuals, and hypothesis tests were conducted using AMOS 22.0. In addition, by the qualitative research, we have examined smartphone usage and the technostress of smartphone usage. Focus group interviews were conducted with 24 ordinary people who purchased and used smartphones in order to verify the users response to the smartphone user manual service.

The avoidance tendency of voice call in younger generation facilitates the growth of mobile O2O service that utilizes Messaging. This study adopted and elaborated original concepts of telephone apprehension to apply phone anxiety to O2O. We examined previous researches related to the ubiquity of service quality, communication ability and anxiety, and then conducted a survey to understand the consciousness of mobile O2O service users. The results show that users with high message intimacy and users with poor logicality are afraid of voice calls. The mobile O2O service is considered useful as a means to replace an unstable situation. In this study, we considered individual characteristics of acceptance factor of O2O mobile service technology, and it was a new attempt to expand telephone apprehension characteristic reflecting current situation.

혁신적인 정보기술이 우리의 일상생활에 빠르게 수용되고 있는 과정에, 일시적으로 수용되었다가 이용이 중단되는 경험을 하기도 한다. 본 연구에서는 마이크로 블로그를 일시적으로 수용한 중국 사용자들을 대상으로 수용 후 이용중단에 미치는 요인을 알아보고자 한다. 실증분석 결과 사용자의 심리요인 중 복잡성과 보안성은 인지된 위험에 모두 영향을 미치는 것으로 나타났으며, 불편함, 혁신성과 주관적 규범은 사회적 위험에만 영향을 미치는 것으로 나타났다. 또한 인지된 위험은 이용중단에 모두 영향을 끼치는 것으로 나타났으며, 특히 복잡성이 가장 큰 영향을 미치는 것으로 나타났다. 이러한 결과를 토대로 향후 마이크로 블로그 사용의 복잡성을 좀 더 감소시키는 것이 필요할 것이다. While innovative information technologies have been adopted quickly into our daily life, we often experience the discontinuance after being temporarily adopted.

모바일 쇼핑은 모든 사용자에게 있어 항상 유용하게 사용되는 것만은 아니다. 주요 원인으로 비사용자의 경우 모바일 쇼핑몰에 대한 심리적, 보안적 취약성 등에 대한 잠재적 요인이 모바일 쇼핑에 대한 거부감을 형성하는 것으로 인지되고 있다. 본 논문에서는 혁신저항모델의 문헌연구를 통해 연구모형을 구성하여, 스마트폰을 이용한 모바일 쇼핑 시 소비자들이 갖는 거부 심리요인들이 모바일 쇼핑몰의 인지된 위험을 통해 구매저항에 어떤 영향을 미치는지 연구하고자 한다. 실증분석 결과 모바일 쇼핑 시 소비자의 심리요인 중 보안성은 인지된 위험에 모두 영향을 미치는 것으로 나타났으며, 부정적 사회영향과 인지부조화는 사회적 위험, 배송위험에만 영향을 미치며, 불확실성은 성능적인 위험에만 영향을 미치는 것으로 나타났다. 또한 인지된 위험은 구매저항에 모두 영향을 끼치는 것으로 나타났으며, 특히 사회적 위험이 가장 큰 영향을 미치는 것으로 나타났다. All of smart phone users not always make a good use of mobile shopping. The main cause is that in case of non-user of mobile shopping, potential apprehension to psychological and security weakness affects building up resistance on mobile shopping. In this paper, we designed models of innovation resistance heavily based on literature reviews and previous studies, and tried to find how perceived risk affects consumer's purchase intention in mobile shopping process. In conclusion, it shows that security, one of psychological factors, affects perceived risk in all aspects, while negative influence of society and cognitive dissonance just affect social risk and delivery risk, and uncertainty also just affects performance risk. Besides, it shows that all of variables made up perceived risk affects resistance of purchase. Especially social risk turns out to be a most influential factor to purchase behavior through smart phone.

This study empirically evaluates the effects of environmental regulation violation on performance in long-term point of view The major findings of this study are as follows: first, our test assesses the association between the propensity of regulation violation and performances (ROA and Tobin-Q) for the total sample. Our results indicate a negative relationship between the propensity of regulation violation and performances (ROA and Tobin-Q), respectively. This implies that firms associated with regulation violation experience a difficulty in operating business than firms not associated with regulation violation. Secondly, our test assesses the association between the degree of government actions from environmental regulation violation and performances (ROA and Tobin-Q) for the regulation violation sample. Our result demonstrates a negative relationship between the degree of government actions from environmental regulation violation and firm value. The analysis indicates that the firms associated with the government actions for regulation violation (prosecution, penalty, temporary shutdown, shutdown, and ban to use specific equipment) experience a decrease in firm value.

Modern society is complex and rapidly changing, and knowledge sharing is needed to acquire and create knowledge. Knowledge sharing is the act of providing information knowledge and know-how of their own in order to cooperate with or help their colleagues. This study presents a research model using social capital theory to explain the mobile knowledge sharing behavior of virtual community members. Based on previous studies, social capital theory is divided into structural, relational, and cognitive aspects. It was composed of social interaction ties as a measure of structural aspect, trust as a measure of cognitive aspect, shared language, shared vision and relational aspect. After collecting survey data, factor analysis and regression analysis were performed using SPSS 22. In this way, we examined how the detailed factors of social capital affect information sharing behavior and how the level of knowledge sharing affects community promotion. The results showed that social interaction ties, shared language, shared vision, and trust affect knowledge sharing. Knowledge sharing has had a positive impact on community promotion. 현대사회는 복잡하고 빠르게 변화하고 있고, 지식을 습득하고 창출하기 위해 지식 공유가 필요하다. 지식공유는 동료들과 협력하거나 이들을 돕기 위해 자신의 정보 지식, 노하우를 제공하는 행동이다. 본 연구는 가상커뮤니티 구성원의 모바일 지식공유행위를 설명하기 위해 사회적 자본이론을 이용하여 연구모형을 제시했다. 선행연구를 기반으로 사회적 자본이론을 구조적, 관계적 그리고 인지적 측면으로 구분하였다. 구조적 측면의 척도로 사회적 유대, 인지적 측면의 척도로 공유 언어와 공유비전, 그리고 관계적 측면의 척도로 신뢰로 구성했다. 설문 자료를 수집한 후 SPSS 22를 이용하여 요인분석과 회귀분석을 실시하였다. 사회적 자본의 세부 요인이 정보 공유 행위에 어떠한 영향을 미치는지, 그리고 지식공유의 정도가 커뮤니티 촉진에 어떠한 영향을 미치는가를 실증 분석하였다. 분석결과 사회적 유대 관계, 공유된 언어, 공유된 비전, 신뢰가 지식 공유에 영향을 미치는 것으로 나타났다. 지식 공유는 커뮤니티 촉진에 긍정적 영향을 끼쳤다.
