이 논문은 기술시장의 성장이 그 기술을 기반으로 한 기술서비스 공급자 시장을 확대시킨다는 것을 실증 분석하였다. 즉, 라이센싱된 기술의 숫자가 증가할수록 기술 공급자의 시장 진입이 촉진된다는 것이 본 논문의 핵심 가설이다. 이 가설을 검증하기 위하여 화학 산업의 기술거래 및 엔지니어링 서비스 데이터를 대상으로 하여, 기술 라이센싱이 증가함에 따라 기술 공급자의 고정비용이 줄어들어서, 기술공급자가 시장에 진입하고자 하는 유인이 증가한다는 것을 검증하였다. 나아가 엔지니어링 서비스 시장의 수요 증가 또한 기술 공급자의 시장진입을 증가시키지만, 가변비용의 대용변수로 쓰인 일인당 임금수준은 그다지 공급자의 시장진입 결정에 영향을 미치지 않는다는 것으로 나타났다.

Cloud-computing is in the limelight with expectation for cost reduction, because it alleviates the burden of initial investment and maintenance cost and based on pay-as-you-use billing policy. However, many suppliers of Cloud-computing service are suggesting diverse and complicated billing policies without consideration for setting reasonable service billing policy and definite criteria of properties to determine service billing system. So companies willing to use Cloud-computing service are hard to understand the billing system and often spend more expensive cost than necessary. Therefore, this study invested billing system properties of four representative suppliers. Based on these properties of billing system, this study found priorities using AHP survey which conducted to experts who are able to make decisions for adopting Cloud-computing in the company using or willing to use Cloud-computing service. We expect that this study can suggest basic guideline for comparing and analyzing properties of Cloud-computing service with standardized and objective method.

Purpose - Considering the environmental issues in corporate management is now a necessity, not an option. In addition, consumers' interest in health and environment has increased rapidly. This study aims to investigate how the management style that pursues environmental protection affects the various outcomes at each management process such as planning, producing and supervising process. Research design, data, and methodology - We surveyed 319 manufacturing companies from April 1 to April 30, 2016. Green purchasing, environmental technology management and management support are selected as independent variables and firm performances as dependent variables. Three analyses including factor, regression and moderating were conducted. Results - Regression analysis was performed to set up hypotheses. Consequently, the total six hypotheses were adopted and then innovative management style showed moderating effect. Conclusions - Companies should consider environmental factors to improve the financial performance in the long term. Especially the cooperative style enhances financial performance by implementing eco-friendly design in cooperation with customers. Also, eco-friendly activities with suppliers could have direct environmental protection effects. Therefore, a manufacturer needs to cooperate with both suppliers and customers to maximize the protection effect. The production of eco-friendly products and implementing eco-friendly design with customers positively affect product quality.

The supplier selection problem is perhaps the most important component of the purchasing function. Some of the common and influential criteria in the selection of a supplier include quality, price, delivery, and service. These evaluation criteria often conflict, however, and it is frequently impossible to find a supplier that excels in all areas. In addition, some of the criteria are quantitative and some are qualitative. Thus, a methodology is needed that can capture both subjective and objective evaluation measures. The Analytic Hierarchy Process(AHP) is a decision-making method for ranking alternative courses of action when multiple criteria must be considered. This paper proposes the AHP-based approach which can structure the supplier selection process and the achievements-based procedure which can allocate order quantities for the selected suppliers In automotive part manufacturers. Also, through the practical case of 'D' automotive part manufacturing company, we shows that the proposed AHP based supplier selection approach and the achievements-based allocation procedure of order quantity can be successfully applied for supplier selection and order quantity allocation problems.

We developed a Part Information Brokering System, namely PIBS, that can inter-link part suppliers and buyers using WWW(World Wide Web). The major contribution of this paper is that the system provides a 3D collaboration environment that enables multiple users to share the same workspace where they cooperatively manipulate part features in real time. PIBS carries out two major functions: one to maintain part data in a part library, and the other to provide the means for the clients to cooperate. An object-oriented database is used for the part library which stores apart information registered by part suppliers. VRML(Virtual Reality Modeling Language) the ISO standard for 3D visualization on WWW, is used to represent 3D part models. Several Java programs have been implemented to support synchronous and a synchronous communication of the 3D models. Once the users are interconnected through the system, a user's manipulation of part objects is transparently and instantaneously transmitted to the others. This means that all the participants can are the same view and movement of the 3D part models. Since the system is developed using a Java applet-server architecture, it requires no additional software other than standard web browser. The prototype system has been successfully implemented, and demonstrated its applicability to virtual 3D part information sharing.

In this study, the effect of innovativeness of external networks on the corporate innovativeness and innovation performance were explored based on web survey data collected from 230 manufacturing companies. Specifically, according to the manufacturers' business categories divided by the technology level, three groups such as advance technology (electronic/IT), mid- to high technology (automobile/machine), and low technology (textile/clothing) companies were investigated to find out which external network influences corporate innovativeness and innovation performance. In the result, textile/clothing companies were not different in company size, history, and innovation effort from advanced technology and mid- to high technology companies. Collectively, the innovativeness of external networks affected corporate innovativeness and innovation performance. In the result by a business category, innovativeness and innovation performance of textile/clothing companies were affected by the innovativeness of competitors, whereas automobile/machine companies in the mid- to high technology group were affected by suppliers. In addition, advanced technology (electronics/IT) were affected by buyers and competitors. These differences suggest that the way to use vertical networks toward upstream (e.g., suppliers) and downstream (e. g., buyers) as well as horizontal networks toward competitors can be different by the business category of manufacturers. The result would provide implications for the academia and the industry.

Even though many Korean consumers have bought environment-friendly fruits, including grapes and mandarins, farmers and suppliers still have little information about how they make a decision for the actual purchase in the real markets. Without the suitable information of purchase behavior of environment-friendly fruits, farmers and suppliers cannot set up the efficient marketing strategy which can create the better agricultural products for Korean consumers. The purpose of this paper is to analyze the consumers' purchase behavior of environment-friendly fruits in Korea. Especially, this study was focused on the grapes and mandarins, through the survey research and the frequency analysis. The results of study in this paper present a few findings useful as follows: First, Korean consumers have the strong concern of environment-friendly agricultural products, including fruits. Second, consumers usually buy environment-friendly fruits by two times per month. Third, consumers generally concern taste, freshness, and food-safety, when they buy environment-friendly grape or mandarin.
