Large-scale discount stores, that were in charge of leading role up to recently, reach the limit of growth because of increasing competition, saturation of domestic market, and shortened product life-cycle. As per the limit of domestic market, large-scale discount stores are trying to various global market entry strategy and global marketing strategy like new store entry, takeover of foreign distribution chain, and global sourcing strategy. In the past, global companies of advanced country have been entering to Asian market with leading position. But, as per the rapid growth of Asian economy in the late 1980's, East Asian distribution companies like Japanese company were trying to enter the Asian market. In Asian market, starting with China, that was relatively not advanced in comparison with economic development, not only western advanced countries but also East Asian countries like Japan and Korea are entering actively for overcome their limitations of domestic market. Many of distribution companies experienced success and failure for various reason already. Korean large-scale discount stores are relatively late starters in Asian market. So, this paper purposed to review global market entry strategy of Japanese large-scale discount stores, and find out strategic implications for successful global market entry strategy of Korean large-scale discount stores.

This paper is on the policy proposal for venture ecosystem. First, one of the three secrets of the US venture ecosystem is the law of 50:50. Angel capital investment is as important as venture capital investment. Although professional angel investors and accelerators account for as much as VC in the venture ecosystem, they are ignored from policy considerations. We argue that the revision of related law is urgent. Second, large US firms invest more in M&As than in internal R&D. Therefore, accelerators and professional angel investors could make effective investment recovery after investing in a startup company. In other words, angel capital does not come in without secondary market development. Angel capital and secondary markets are the two pillars of the venture ecosystem. The government alone is difficult to develop a secondary market. This is why the private sector should come in and introduce corporate venture capital (CVC). Third, we believe the policy direction for national economic growth should be extended from the startup to scale-up. This is because the startup's sales and job creation will start in five years. While the previous study focused on funding (venture financing), this paper aims to balance all three stages of a venture: startup, growth, and recovery, which are the life cycle of a venture company or venture investment. In particular, we propose specific policies in each chapter to improve practical application.

Previous studies, Technology Acceptance Model (TAM) and Post Acceptance Model (PAM) have a little limitation in time series analysis. To solve this limitation, we used system dynamics as research methodology and designed simulation model based on TAM and PAM. Moreover, we designed new simulation model which can analyize time series data in customers' demand change from initial acceptance to post acceptance. This study targeted domestic mobile phone market. The simulation results showed that diffusion graph was similar to real data. That means we validated our simulation model. Since the simulation model offers the graph of customer's demand change by time, so it can be useful as a leaning tool. Therefore, we think this study helps IT companies use the model for forecasting of market demand.

This study was conducted on 1,865 drunk elderly people who had teeth that were over 65 years old. As a result of analysis of factors related to tooth extraction, the higher the income, the lower the income, the higher the risk of having to remove teeth from smokers, poorer oral health status, and no oral hygiene products. The difference was statistically significant. In order to identify the risk factors of tooth extraction for the elderly and prevent tooth loss early and to extend the life of residual teeth as much as possible, it is necessary to improve the drinking culture and seek oral health care strategies in the previous life cycle, not the present, Oral health policy should be pursued.

기후변화 위기는 유사 이래 인류가 직면한 가장 큰 도전으로 범정부적 글로벌 문제로서 이를 해결하기 위한 다양한 정책들이 범국가 차원 혹은 세계적 기업들에 의해 발표 혹은 시행되고 있다. 이러한 기후변화위기와 탄소배출 저감을 위한 대표적인 대응 방안 중 하나가 바로 재생에너지의 확대·보급 노력이다. 그러나 재생에너지는 날씨와 계절 등 자연환경의 영향을 받는 에너지원으로써 간헐성, 변동성을 가지므로, 시간대별 발전량 예측과 전력공급 안정성에 어려움이 있다. 이러한 문제를 해결하기 위하여 재생에너지 발전은 석탄화력 발전과 달리 전력의 수요와 공급의 균형을 위한 에너지저장장치(Energy Storage System, 이하 ESS)가 있어야 한다. ESS는 전력공급 안정성 향상과 전력 수급의 유연성을 제공하는 장점이 있지만, 초기 설치비용이 높은 단점이 있다. 특히, 배터리 기반 ESS의 경우 높은 구축 비용과 한정적인 충. 방전수명으로 인하여 대용량 ESS로써의 역할 수행에는 분명한 한계가 있다. 하지만 재생에너지와 연계한 ESS로 양수발전댐을 활용할 경우 장주기, 장수명, 대용량 에너지 저장에 매우 합리적인 수단으로 판단되었다. 다만, 양수발전 댐 구축에는 토목공사로 인한 환경 훼손이라는 문제점도 존재한다. 본 고에서는 지역 분산형 소규모 양수발전(Pumped Storage Hydropower, 이하 PSH)댐 구축 및 운영기술 개발을 통해 지역 전력공급과 전력 수급을 조절하면서 변동성 재생에너지를 안정적으로 사용할 수 있는 방안을 소개하고자 한다. 특히, 해당 기술은 지역별 특성에 맞춰 유연하게 설치할 수 있으며, 대규모 토목공사로 의한 환경적 부작용을 최소화할 수 있다. 또한 소규모 PSH는 지역의 저수지 및 수자원을 이용하여 에너지를 저장함으로써 변동성 큰 재생에너지의 유연화 대응과 동시에 안정적인 에너지 공급이 가능하다. 본 고에서는 재생에너지의 확대·보급에 따른 문제점과 대표적 ESS 기술들을 분석·소개한다. 지역분산형 소규모 PSH 기술개발 연구기획 내용 소개를 통하여 전력 생산 및 공급의 탈중앙화를 달성하고, 지역별 변동성 재생에너지의 안정적 활용과 지역 전력공급 특성 및 전력 수급에 대응할 수 있는 방안을 제안하고자 한다.

Because a product in the car industry has a short life cycle in recent years, the process planning and the manufacturing lines have to be changed frequently. Most of time, repositioning an existing facility and modifying used control information are faster than making completely new process planning. However, control information and control code such as PLC code are difficult to understand. Hence, industries prefer writing a new control code instead of using the existing complex one. It shows the lack of information reusability in the existing process planning. As a result, to reduce this redundancy and lack of reusability, we propose a SOS-Net modeling method. SOS-Net is a standard methodology used to describe control information. It is based on the Device Structure which consists of sensor information derived from device hardware information. Thus, SOS-Net can describe a real control state for automated manufacturing systems. The SOS-Net model is easy to understand and can be converted into PLC Code easily. It also enables to modify control information, thus increases the reusability of the new process planning. Proposed model in this paper plays an intermediary role between the process planning and PLC code generation. It can reduce the process planning and implementation time as well as cost.

Today, many firms face the environment of high uncertainty and severe competition due to the rapid technology development and the diverse needs of customers. In the business environment, one of the most important ways to gain sustainable competitive advantage and future growth engine is related to NPD (New Product Development), which is a very important issue for practice and academia. Thus, this study intends to provide new values to practitioners and researchers related to NPD by analyzing current research trends and future trends in NPD field. For this, we bibliometrically analyzed keyword networks which consist of keywords that were already published in the eminent journals from Scopus database to generate insights that have not been captured in the previous reviews on the topic. As a result, we could understand the extant research streams in NPD field, and suggest the changes of specific research topics based on the connected relationships among keywords over the time. In addition, we also foresaw the general future research trends in NPD field based on the keywords according to preferential attachment processes. Through this study, it was confirmed that NPD keyword network is a small world network that follows the distribution of power law and the growth of network is formed by link formation by keyword preferential attachment. In addition, through component analysis and centrality analysis, keywords such as Innovation, New product innovation, Risk management, Concurrent engineering, Research and development, and Product life cycle management are highly centralized in NPD keyword network. On the other hand, as a result of examining the change of preferential attachment of keywords over the time, we suggested the required new research direction including i) NPD collaboration with suppliers, ii) NPD considering market uncertainty, iii) NPD considering convergence with the other academic areas like technology management and knowledge management, iv) NPD from SME(Small and medium enterprises) perspective. The results of this study can be used to determine the research trends of NPD and the new research themes for interdisciplinary studies with other disciplines.

Companies' efforts to secure and sustain a competitive advantage in the market may also appear in the form of new product development. This has increased the importance of leveraging knowledge from other companies in a global competition that is accelerating with an accelerating product life cycle and the development of transportation and communications. In order to create valuable knowledge through the exchange and combination of knowledge, the absorptive capacity of the recipient of the knowledge should be considered as important, but also the knowledge protection tendency, which is characteristic of the knowledge transferor, should be considered. However, studies that considered these factors at the same time were very limited. This study examines the effect of suppliers 'absorptive capacity and buyer' s knowledge protection on new product development performance during the joint development of new products. In addition, we investigated the interaction effect between supplier's absorption capacity and buyer's knowledge protection tendency. For this purpose, data were collected for automobile industry, electronics industry and defense industry, where joint development of new products occurred frequently, and statistical verification was performed by regression analysis. The results showed that the absorptive capacity of the supplier was positively correlated with the performance of the new product development, and the buyer 's knowledge protection tendency had a negative relationship with the new product development performance. In addition, the absorptive capacity of the supplier and the buyer 's knowledge protection tendency have an interaction effect on the new product development result. These results suggest that suppliers' absorption capacity is an important factor in the joint development of new products, but suppliers with superior absorption capacity may have a negative impact on new product development performance if buyers have a negative attitude toward knowledge transfer.

While the cost of technology development is increased, the life cycle of products and services that have been developed has become progressively shorter. Open innovation have been increasing by company as a strategy to respond to the rapidly changed market. Technology transfer from universities is one of the typical means of technological innovation. Although a university has invested significant resources in R&D, the results has been neglected. Therefore, at the moment, research is needed about the outcomes and efficiency of technology transfer at universities. In the previous research, since most of studies focus on the analysis of factors that influence the outcome of technology transfer, in this study, targeting domestic universities, the efficiency of technology transfer at the university was analyzed. In addition, differences in the efficiency of different types of university is verified. Consequently, universities specializing in technology and industry has high-efficiency than the others. There is no significant difference between the groups of universities whether or not to participate in Technology Licensing Office(TLO). More efforts are required for successful results of TLO in Korea. This study is expected to be able to provide reasonable indicators on technology transfer for further research.
