This study investigates factors, which affect subjective judgment of Smartphone users when they switch to a new product or other mobile carrier, and examine a relationship between switching intention and switching expected performance through users of in Korea and China. The results of the study showed that switching intention is positively associated with switching expected performance in both Korean and Chinese users. Brand reliability, functional quality, and general climate for Smartphone business have a significant impact on switching intention in both countries. In addition, personal innovation has a significant impact on switching intention of Korean users but Chinese. However, content quality has the effect on switching intention of Chinese user but Korean. This study provides useful strategies for switching behavior of Smartphone users of two different countries in the mobile industry.

This research examines the factors that influence a consumer's decision to switch to new self-service technologies. The model related to attitudes, anticipated outcomes and intentions to change a behavior was assessed using structural equation modeling at the context of a banking industry. The results revealed that 1) an attitude toward a staff, Internet banking, and an ATM would influence an attitude toward a bank, 2) an attitude toward Internet banking and ATM influence utility and enjoyment, and an attitude toward Internet banking and staff affect social acceptance, 3) an attitude toward a bank was positively associated with enjoyment, 4) an attitude toward Internet banking had a positive effect on the intention, but an attitude toward an ATM had a negative one, and 5) both anticipated outcomes, enjoyment and social acceptance, were found to influence an intention to change behavior, but utility was found to affect negatively.

This study explores the effectiveness of employment-oriented welfare state by analyzing the mediating role of employment rate on the relationship between public welfare effort and fiscal soundness. Notably, this study considers the quality of employment into the analysis: part-time work, involuntary part-time work and low-wage work in analysis. The data sample consists of 18 OECD countries which initiated employment-oriented welfare strategy after the crisis of welfare state. An analysis was conduct based on Baron & Kenny(1986)'s method and panel two-stage model to handle the endogeneity problem. The results show that while the high level of public welfare effort negatively affects the fiscal soundness if it contributes to boosting employment rates, it has positive effects on the fiscal soundness. However, when the incidence of involuntary part-time employment and low-wage employment is high, the mediating impact of employment rate on the fiscal soundness disappears. This study argues that unless the quality of employment is taken into consideration, the positive effect of employment-oriented welfare state strategy to improve the fiscal soundness is not fully guaranteed.

This study identifies possible determinants that may have influences on the switching behavior from the current payment system of credit or check cards to the easy payment service based on push-pulling-mooring model. And this research empirically tests how those determinants affect switching intention to the easy payment service. The moderating effect of policy expectation is also taken into account. The findings show switching intention to the easy payment service is influenced by the followings: dissatisfaction with the current payment system as a pushing factor, perceived easy of use and trust in easy payment service as pulling factors, and affective/cognitive inertia and unfavorable subjective norm as mooring factors. The results also show that moderating effect of policy expectation exists in the relationship between perceived ubiquitousness and switching intention.

CB(Convertible bond) is mezzanine security that have the characteristics of bonds and stocks. From the perspective of investors, the purpose of the research is to empirically investigate the degree of investment efficiency of CB and to suggest efficient investment plans. The research method investigated the maturity interest rate, conversion price, and conversion date for CB, and then linked it with daily stock price fluctuations after the conversion date to determine the degree of investment efficiency and stock conversion effect of CB. As a result of the study, it was analyzed that the ratio of the conversion price exceeded days was only about 1/4 of the conversion date, so the investment efficiency was low. The conversion day yield was -6.3% on average and the maturity day yield was -5.2% on average, showing a minus return on average, which was calculated differently from investor expectations. It was analyzed that the number of stocks with a minus conversion day is 2.4 times greater than the number of plus stocks and 3.7 times more than the number of plus stocks with a minus maturity return, so the expected return on stock conversion of CB is low. The research contribution was derived from the problem that the expected rate of return of CB is not high, and it is that the investor's point of view when purchasing CB was established.

세계적으로 화학, 생물학 및 방사능 무기의 근절을 위해 CWC와 같은 여러 가지 국제조약이 결성되고 있으나 힘의 논리와 자국 이익의 논리가 앞서는 한 근본적인 근절은 어려운 실정이다. 이 글에서는 화생방전의 피해를 최소화하기 위한 통합 시스템을 소개하고 각 시스템에서 필요한 기술을 나열하였다. 특히 이러한 기술들 중에서 많은 부분이 원자력 분야에서 개발되었으나 개발 중이어서 군용으로의 전환이 용이할 것으로 기대된다.

오늘날의 기업들은 글로벌 갱쟁환경과 고객 기대수준의 상승 등의 이유로 글로벌 소싱 및 기업간 전략적 제휴나 협업 등에 많은 관심을 기울이고 있다. 공급사슬관리(Supply Chain Management: SCM)는 기업과 기업, 기업과 고객 사이의 물류와 정보로 이어진 네트워크를 가능하게 실현할 수 있는 혁신기법이다. 본 논문에서는 공급사슬구조를 하나의 네트워크로 파악하여 공급네트워크, 전환네트워크, 유통네트워크라는 유형으로 구분하였고, 공급사슬구조에 따라 SCM 활동에 차이가 있으며, 경영성과에도 차이가 있음을 입증하였다. 따라서 본 논문은 현재까지 사례연구로 행해지던 네트워크의 분류를 이용하여 각 공급사슬구조에 따른 SCM의 활동 및 경영성과에는 차이가 있음 실증분석을 통하여 입증하였다는데 의의가 있다.

This study analyzes how expectations, perceived performance and expectation-disdonfirmation of the recreation-forest visitors affect their satisfaction and revisit using path analysis. These results which would maximize visitors' satisfaction and revisit will enhance recreational forest management. As the results, factors of expectation-disconfirmation positively effected visit satisfaction are experience-facilities, natural resources, access and valley factors. In addition, natural resources factor effects positively their selection-satisfaction. Also, visit-satisfaction and selection-satisfaction effect positively to their revisit intention. This result show seeking the visitors' satisfaction through recreation-forest manager try to expectation-disconfirmation of experience-facilities, natural resources, access and valley factors exchange to positive expectation-disconfirmation.
