It is true that the Korea has performed its intensive ecomoic development plans since early 1960's, in the course of the development, the medium and small industries have played important role in its national ecomy, in the areas of emplogment opportunity, balanced regional developement, export promotion, and high return of capital in vestment. Because the govern ment's economic policy has been give mainly to big enterprises, medium and small industries have been lilatively depressed. This problam, seens to be one of the major obstacles to achieve continuous economic growth of the nation. Korea has to restructure its economic system. and solve the unfavorable relationshap between, the medium and small enterprise. So we have to promote medium and small industries. To this we have to solve some problems as follows, 1. To strenthen the international competitive power. 2. To support the components industries. 3. To open up a foreign market 4. To stabilized the supply of raw marterial. 5. To raise the credit degree... etc.
관광산업에서 온라인커뮤니티특성, 신뢰, 충성도, 구매의도 간의 관계 분석

This study tried to analyzed the relationship between online community characteristics, trust, loyalty and purchase intention in order to suggest to a methodology for performance 6hypothesis were constructed for analysis based on previous literature review. For the empirical study, a survey was performed from March 15, 2013 to May 15, 2013 and 253 of 300 questionnaires were used as the final data for analysis by respondents who have been experienced in online community. The results of empirical analysis shows that online community characteristics gave significant effect on trust, loyalty and purchase intention and trust gave positively effect to loyalty and purchase intention. Besides loyalty also positively affected on purchase intention. These result explains that firms which try to create customers must built high level of online community characteristics, and should be realized construction of trust and loyalty for maintenance of created purchase intention. For this, management of online community should be required through the high level of performance. These result explains that firms which try to take superior of performance should be realized in online community characteristics, trust, loyalty and purchase intention. This research provides many suggestions but the critical point of the research demonstrates a limitation of generation because of not selecting all online communities as the target samples and online community characteristics. The research is required to choose more extensive online community.

The objective of this research is the explanation of so, this study ends with recommandations concerning the management strategy which can be taken by korea's enterprise in their FDI ventures, why foreign direct investment are carried by internalized patterns. It takes as its starting point the market imperfection, more specifically, internalization theory. The model postulates the main groups of factors are relevant to the internalization decision: (1) from specific factors which reflect the ability of the management to organize an internal market. (2) transaction cost relating to the transaction uncortainty and the opportunitism. (3) unnatural market imperfection relating to the government's intervention therefore, a hypothesized model is developed based on inernalization structure. The hypothesis of this study as follow : The greater the firm-specific advantage, the transaction uncertainty, the opportunitism, the government's intervention, under internalization, the greater the firm's performance.

A hardware-in-the-loop simulation (HILS) method for e-bikes driven by in-wheel brushless direct-current (BLDC) motors was implemented on a motor dynamometer using a powder brake. First, a coastdown test on a real road was conducted to acquire data for use in analyzing the correlation between the vehicle speed and the load on the road. Second, speed, voltage, and current data were acquired from an e-bike operating on a real road without braking and pedaling. To verify the applicability of the HILS method used in this study, a set of dynamic simulations on a motor dynamometer with real hardware were conducted to simulate a field driving test of an e-bike. The motor dynamometer simulated the road load through the powder brake, and the load of the dynamometer was controlled using a closed-loop proportional–integral (PI) controller. A comparison of the field test results and the HILS results indicate that the HILS method can adequately simulate the e-bike’s road load, including its running and inertial resistances.

The effect of inter-band transition on surface plasmon resonance in gold thin film was investigated. We induced localized inter-band transition in the film by using incident light on its surface from a green laser (532 nm) source, and the surface plasmon resonance forinter-band transition was investigated at different wavelengths. It was determined that the reflectivity of blue light (450 nm) was sig-nificantly reduced in the region where the green laser was incident. We demonstrated that this decrease is mainly due to the couplingbetween the blue light and the surface plasmon resonance of excited electrons in higher energy states, based on experimental results for the incident and polarization angle-dependent reflectivity of the blue light.
