가상화폐는 법정통화가 금융위기나 통화정책 등에 심각하게 영향을 받아 발생하는 문제점으로 시작하여 국가나 신용기관에 독립적인 전자지급결제시스템을 갖추는 것을 목표로 등장하게 되었다. 대표적인 가상화폐인 비트코인은 국제적인 유통수단으로 활용되고 있으며, 일부 국가에서는 납세 및 기타 법률과 같은 규제를 통해 관리되고 있을 정도로 영향력이 있는 가상화폐이다. 본 연구에서는 비트코인의 개념 및 현 상황에 대해서 분석한 후, 모바일 환경에서 채굴되는 M-Bitcoin을 제안하였다. 그리고 M-Bitcoin이 암호통화로써의 가치를 가질 수 있도록 신뢰성 확보를 위한 기술을 적용하고, 차후 현실에서 서비스되는 과정에 대해 연구하였다.

본 연구는 판매노력을 열심히 일을 하는 것과 효율적으로 일을 하는 것으로 구분하고 판매노력에 대한 감독자의 정보제공과 판매원의 감독참가의 효과를 알아보는데 역점을 두고 수행되었다. 판매원의 감독참가와 감독자의 정보제공은 종업원이 자신들의 목표와 성과 그리고 능력과 활동에 관한 내용을 능동적으로 인지하게 함으로서 종업원의 지식수준을 높아지게 하고, 판매원에게 기대되는 역할을 인지하는 하는 것으로 나타났다. 한편 종업원의 지식수준은 종업이 일을 열심히 하고, 효율적으로 하는 정도에 긍정적인 영향을 미치고 판매원으로 하여금 판매직무에서 본인에게 기대되는 것이 무엇인지, 자신이 해야할 일이 정확히 무엇인지를 인지하게 하는데 긍정적인 영향력이 있음을 알 수 있었다. 그런데 역할명료성이 일을 열심히 하게 하는데 영향을 미치는 것으로 나타났지만 효율적으로 하는 효과는 없는 것으로 나타났고, 오히려 감독통제수단으로서 정보제공이 판매원이 일을 효율적으로 수행하게끔 하는데 유의적인 직접효과가 있음을 발견하였다.

With the intensity of competition and the standardization of technical attributes in telecommunications service market increasing, differentiated activity and customer experience in service encounter is regarded as an important means for creating customer value, however, there is a dearth of good literature examining what MOT activity is composed of according to consumption chain, and how service quality of MOT has influenced customer performance. Especially there exist various services across different phase of Product life cycle(PLC) in household telecommunication service market, customer requirement for MOT might depend on whether its phase is introduction-growth stage or maturity-decline stage, the empirical study is completely lacking. This study classified household telecommunication services into two types by PLC, VOIP and IPTV as Introduction-growth stage services, Internet and PSTN as maturity-decline stage service, and investigated whether there exists a gap between service types in how consumer have experienced MOT, what they consider as important and the relative importance of quality dimension how service quality of MOT has influence on consumer performance. The empirical result from 858 participants shows that there is a difference in consumer experience and requirements across different phases of the PLC, tangibles and assurance are regarded as the most important service quality factors which have a positive influence on customer performance (consumer satisfaction, repurchase intention and word of mouth) at the introduction-growth stage, whereas, reliability, empathy and interactivity are at the maturity-decline stage. Finally, managerial implication is made, limitation is clarified and a direction for further studies is suggested.

Total 83model forest owners in Korea were investigated to find out the relationship between their attitudes toward tree felling (or propensity to felling) and selected six independent variables, i.e, owner's age(X1), educational level(X2), forest land area (X3), socioeconomic status (X4), communication (X5) and sociopsychological factor(X6). The dependent variable was measured by Liken attitude scale, and analyzed by multiple regression. Major findings of the study are summarized as follows: 1) The degree of the propensity of felling is relatively high. The communication and sociopsychological variables are negatively, but education level is positively related to the dependent variable. 2) The multiple correlation coefficient between felling-attitude score and six independent variables is 0.5322. Of the variance of this sttitude score, about 13 percent can be explained by communication variable, 6 percent by sociopsychological variable and other 6 percent by age variable. 3) The model owners' attitudes toward felling are positively correlated with there sources of communication variable, i.e. personal contact, social participation and mass media contact. The multiple correlation coefficient between felling-attitude score and three sources of communication variable is 0.4049. This means that 16 percent of the variance of the attitude score can be explained by three sources of communication, that is, 9 percent by personal contact, 5 percent by social participation and 3 percent by mass media. 4) The fatalistic, untrustful and non-ambitious personalities were positively, but conservative personality negatively related to the propensity to tree felling. The multiple correlation coefficient between seven different personalities and the dependent variable is 0.5461. Of the variance of the dependent variable, 11 percent can be explained by untrustful personality, and other 11 percent by nonambitious personality.

Patent litigation has been considered as a tool to protect and facilitate innovation. Ironically, yet, the misguided uses of patent litigation as a strategic tool for vigilance against competitors are acting as a hindrance for innovation. Previous studies show that the better the quality of a patent, the higher the chance of the patent being litigated. Therefore, it is particularly important for the innovating firms to take strategic precautions to minimize the risk of patent litigation. This study investigates the moderating role of firms' past alliance experiences on the relationship between patent quality and patent litigation from the perspective of a defendant. A unique dataset on patents, infringement lawsuits, and firm performances in the printed electronics industry confirms that firms' previous alliance experiences mitigate the impact of patent quality on infringement litigation. For instance, the results confirm that the presence of past alliance experience reduces the litigation rate by 33% for firms with median-quality patents. This paper makes two major contributions. First, it contributes to the literature on alliance experience by confirming its role as a reputation in mitigating future litigations. Second, this paper contributes to the literature on patent litigation by identifying a unique moderator, i.e., alliance experience, on the linkage between patent quality and litigation. An innovating firm is likely to become an alleged infringer under a false accusation. Therefore, this paper focuses on firms that partake in infringement lawsuits unwillingly. Despite the importance, to the best of our knowledge, this is the first study to investigate patent litigations from the perspective of defendants.

This study examines the key factors which influence the strategic consideration and intention of adoption of internet marketing of small-and-medium sized companies, based on theoretical consideration of innovation diffusion theory and previous studies related. The result of analysis shows that the degree of market competitiveness, customer dependency, the level of internet marketing knowledge and experience have significant effects on both of strategic consideration and adoption intention for internet marketing. Also, learning commitment has negative influence on strategic consideration only, while environmental dynamism does on adoption intention. Comprehensively, the findings implies that firms consider selection of internet marketing to reduce the severity of competitiveness and that firms which has more knowledge or experience about internet marketing seems to consider selection of internet marketing through the perception of the effects of internet marketing or possible access to internet marketing. Based on the findings that the level of internet marketing knowledge and experience have much significant effects on both of strategic consideration.

The purposes of this study are to estimate mean willingness to pay (WTP) for preventing forest fires by contingent valuation method (CVM), and to calibrate the variables affecting WTP. The forest fire prevention fund was utilized as a payment vehicle to elicit respondents' willingness to pay (WTP). A total of 500 adults who reside in Seoul Metropolitan area were selected by two-stage cluster sampling and conducted the face-to-face interview. The scenario was designed to meet the requirements for double-bounded dichotomous choice CVM. More than half of the respondents (64.6%) have a willing to pay for the fund. The mean WTP was \4,532. Therefore a total WTP for the population was \34,165,758,000. The calibration of Weibull proportional hazard model showed that education level, environmental conservation intention and negative consciousness about the effect of forest fire were independent variables strongly influencing the WTP.

Coast guard organization has very different working environment with other general administrative organizations or police organizations. Because they are charging various coastal crimes and safeties by using war vessel at ocean, it was expected that in case of coast guard officers, the impact on organization commitment for each trust factor within organization has the differentiation with other administrative organizations. Core of results by conducting positive research is as following: It is indicated that for coast guard officer, organization trust factor most strongly impacts on organization commitment, and of social trust factors, colleague trust factor more impacts relatively than boss trust factor. Then, when searching the difference of trust factor recognition depending on population sociological properties of coast guard officers, it is indicated that the one having the experience of working at war vessel has more trust to its colleagues than the one having not and executives more trust their boss than non-executives. The reason why the trust to colleague is higher than to boss is recognized that it is caused from deep relationship with colleagues who work and live together when considering working conditions of security vessel.
