This paper studies the impact of regulatory approaches on innovation and entrepreneurship. As technological progress and environmental changes avail new business opportunities to innovative startups, many governments find it difficult to regulate new and unprecedented businesses promoted by the innovative firms. In order to provide academic and practitional implications on the regulatory design with which to support innovation and entrepreneurship, this paper aims to review classical theories on the demand and supply of regulation as well as empirical research on the impact of regulation on market entry and incentives for innovation. Based on the findings, this paper discusses the recent controversies around the regulatory approaches on new businesses pursued by startups, which are as known as the "positive regulatory approach" vs. "negative regulatory approaches" among practitioners and policy makers in Korea. This paper claims that the Korean context provides an useful opportunity to investigate how the ongoing transition of the once "fast follower" economy into a pacesetter one changes the nature of businesses pursued by firms, investors, and related market players and, accordingly, calls for the changes in the way the government intervenes in markets to regulate businesses of firms. By doing so, this paper sheds light on the role of the government in establishing an entrepreneurial ecosystem where innovative ideas of startups can be tested and nurtured.

In the information society, characterized by knowledge and network economy, standards and standardization became a very important factor in determining the competitiveness of nations and firms. This paper defines the concept of standards and standardization and reconstructs the theory on the relationship between standards and technological innovation. The findings and policy implications are as follows. First, the effect of standards on technological innovation differs according to its function(compatibility, minimum quality, information, and variety reduction) and types(product-related and non-product). On the other hand, standards can impede technological innovation. Second, in terms of national innovation system(NIS), standards are an infra-technology, which is a public good. Therefore, government should decide the optimal level of investment on standards and standardization. Third, since standards foster firms' innovation over the all stages of business activities company, industry, and government should connect standardization activities with R&D, manufacturing, marketing, supply chain, and technology transfer, Fourth, standards play an important role in product innovation as well as process innovation. Based on these theoretical background and hypotheses, the empirical study of the Korean firms is needed.

연료개질기는 연료전지 시스템의 핵심 구성요소 중의 하나로 도시가스로부터 수소를 생산하는 역할을 담당한다. 연료개질기는 주로 탈황, 수증기 개질, 수성가스 전이, 선택적 산화 반응의 4단계로 구성되어 있으며 이 중 상온 탈황부분을 제외한 나머지 부분은 일체화 설계를 통해 제작된다. 탈황의 경우 도시가스에 포함된 부취제인 황화합물를 제거하여 후단에 위치한 촉매층이 황에 의해 피독되는 것을 막는 역할을 하며 주로 상온흡착식 탈황제를 사용한다. 황이 제거된 도시가스는 물과 함께 연료개질기로 도입되어 수증기 개질반응을 통하여 수소, 일산화탄소, 이산화탄소 및 소량의 메탄과 미반응 수증기로 구성된 개질가스로 전환된다. 이후의 수성가스 전이반응에서는 일산화탄소가 물과 반응하여 수소 생산량을 늘리며 동시에 일산화탄소의 농도를 낮추게 된다. 또한 고분자 전해질 연료전지에 공급되는 개질가스는 선택적 산화반응을 통하여 일산화탄소의 농도를 10ppm이하로 유지하게 된다. 이러한 기능의 연료개질기 개발의 주요 이슈로는 컴팩트화 및 고효율화이며 이 두가지 요소를 고려하여 연료개질기를 설계하여야 한다. 연료전지 시스템의 전체부피를 줄이기 위한 노력의 일환으로 연료개질기의 컴팩트화가 요구되는데 가정용 연료전지 기술 선진국인 일본 제품의 경우 $1Nm^3/h$급 연료개질기의 부피는 20L정도로 알려져 있다. 또한 연료전지 시스템의 효율은 연료개질기의 개질효율과 연료전지 스택의 발전효율의 곱으로 계산되기 때문에 연료개질기의 연료개질 효율은 전체 시스템의 효율에 직접적으로 영향을 미치게 된다. 한국에너지기술연구원에서는 수소생산량 기준 $1Nm^3/h$급 연료개질기의 개발을 완료하였으며 크기 및 효율면에서 선진국 제품과 비교하여 동등 또는 우위의 수준을 달성하였다. 연료개질기 내부의 혼합 및 분배 구조를 개선하고 각 촉매층의 최적 배치를 통해 연료개질기의 부피를 최소화 하였으며 연료개질기 내부에서 고온부위와 저온부위 사이의 최적 열교환을 통해 열효율을 극대화 시켰다. 현재 개발된 $1Nm^3/h$급 개질기의 단열 후 부피는 13.5L 그리고 단독운전 시 열효율은 80%(LHV)로 측정되었다. 또한 $1Nm^3/h$급의 연료개질기의 스케일-업 설계를 통하여 수소생산량 3, $5Nm^3/h$ 규모의 연료개질기를 개발하였으며 성능평가가 진행 중이다.

본 연구는 주류 제조과정에서 발생하는 생전분발효 부산물을 펠릿(pellet)연료로 전환하는 과정에서 효율적인 방법에 대해 기술한다. 술을 정제하는 과정에서 발생하는 주박을 펠릿화하고 재생청정에너지인 폐자원의 효율성을 높이기 위한 방법을 제안한다. 술을 정제하고 남은 지게미를 주박(酒粕, 술지게미)이라 하고 흔히 부드러운 것을 단단하게 뭉친 알갱이를 펠릿이라 한다. 현재 펠릿화는 폐목재를 분쇄후 성형, 가공하여 목재펠릿을 만들어 상용화하고 있다. 목재펠릿은 성형, 가공하는데 비용이 주박보다 많이 들고 열량도 더 낮음을 확인하였다. 목재소에서 나온 나무(톱밥)와 주박을 열량측정기를 이용하여 측정한 결과로 나무는 약 1850 Kcal이고 주박은 약 1989 Kcal가 측정되었다. 나무는 일반 목재소 세 곳에서 채취한 것이고 주박은 막걸리, 약주 및 청주의 술지게미를 실험에 사용한다. 주류업체에서도 술을 정제하고 남은 주박을 처리하는데 많은 곤란과 비용이 든다. 또한 주박을 해양에 투척하여 처리해 왔으나 2012년부터 해양투기가 금지되어 더욱 처리에 곤란을 겪게 된다. 최근 주박을 토양개량제(비료)로 개발하여 사용하기도 하나 본 연구에서 제안하는 장점은 농산물을 재배해서 주류제조시 발생되는 주박을 펠릿화하여 연료로 사용하고 남은 재를 토양개량제로 사용하는 장점이 있다. 제품의 전체 라이프 사이클을 통해 환경으로 방출되는 모든 것을 가능한 한 0(zero)으로 하는 활동인 제로-이미션(zero-emision)이 된다. 이는 단순히 배출량만을 줄이는 것이 아니라 폐기물을 유용한 자원으로 활용한다는 측면이 가장 큰 이점이 된다. 주박의 효율성을 높이기 위해 주박을 종류별로 주박과 목재를 섞는 방법으로 열량을 측정하였다. 먼저 열량이 높은 순서로 막걸리 주박과 약주 주박의 비율을 1:1, 1:0.5, 1:0.2, 두 번째 막걸리 주박과 청주 주박의 비율을 1:1, 1:0.5, 1:0.2, 세 번째 막걸리 주박과 나무 톱밥의 비율을 1:1, 1:0.5, 1:0.2로 섞어서 열량을 측정하였다. 열량이 높은 순서는 세 번째(2015Kcal), 두 번째(1995Kcal), 첫 번째(1868Kcal)의 순이었다. 가장 열량이 높은 막걸리 주박과 나무 톱밥을 섞은 것이 가장 효율성이 높다. 주박 펠릿의 장점은 친환경적인 소재이고 지속적으로 재생이 가능한 에너지원이다. 더욱이 주박 펠릿은 발열량이 높고 다른 바이오매스 원료에 비해 청정하다는 큰 장점을 지니고 있다. 또한 사용에 소요되는 유지 관리비용을 최소화할 수 있고 자동화가 가능하여 사용에 편리하다. 가격면에서 화석연료에 비해 안정적이고 체적 또한 작아 이송의 큰 장점을 가지고 있다. 현재 펠릿의 경우는 목재펠릿이 제품화되어 있지만 주박을 이용하여 제품의 펠릿화를 통한 연료원으로 사용하는 경우는 전 세계 전무한 상태로 폐자원을 재사용하는 효율성이 제시된다. 향후 과제로 주박을 이용한 펠릿 연료원의 기술이 개발되고 기계적인 시스템을 개발하면 저탄소 녹색성장 신재생에너지 연료의 획기적인 미래형 에너지시스템이 될 것이다.

The objective of this study is to develop a supply chain-based freight distribution channel choice model considering shippers' logistics behaviors which will be used for freight demand estimation. For this purpose, this study utilized the distribution channel data of the petrochemical and automobile industries collected by KTDB center. The distribution channel choice models for these industries were developed by including transport mode, time, cost, and shipment size. It was found that the multinomial logit model with transport cost, time and shipment size is the best, and as shipment increases, bigger transport mode is preferred. Generally direct distribution channel with small truck was preferred over the one using distribution center and/or big truck.

Conjugated linoleic acid (CLA) concentrations of commercial yoghurts and the ability of dairy starter cultures to produce CLA were investigated. The CLA contents of yoghurts were in the range of 4.1~14.8 mg/l00 g. CLA contents in yoghurts depended on the amount of milk used for raw material. Regression test showed positive correlations between CLA concentrations and selected fatty acids (stearic acid, oleic acid, linoleic acid and linolenic acid) of lipids in yoghurts. Among the 67 commercial dairy starter cultures tested, one of Lactobacillus acidophilus, one of Lactobacillus casei and three of Streptococcus thermophilus were found to be capable of converting free linloeic acid to CLA and cis-9, trans-11 octadecadienoic acid presented more than 70% of the total CLA formed. The CLA conversion rate of the screened strains ranged from 6.1% to 8.6% in whole milk for 24 hours at 37$^{\circ}C$.

It is more salient in the high-tech industry to cooperate even among competitors in order to promptly respond to the changes in product architecture. In this sense, 'co-opetition,' which is the combination word between 'cooperation' and 'competition,' is the new business term in the strategic management and represents the two concepts "simultaneously co-exist." From this view, this study set up the research purposes as follows: 1) investigating the corporate managerial and technological behavioral characteristics in the co-opetition of the global display industry. 2) verifying the emerging factors during the co-opetition behavior hereafter. 3) suggesting the strategic direction focusing on the co-opetition behavioral characteristics. To this end, this study used co-word network analysis to understand the structure in context level of the co-opetition. In order to understand topics on each network, we clustered the keywords by community detection algorithm based on modularity and labeled the cluster name. The results show that there were increasing patterns of competition rather than cooperation. Especially, the litigations for mutual control against Korean firms much more severely occurred and increased as time passed by. Investigating these network structure in technological evolution perspective, there were already active cooperation and competition among firms in the early 2000s surrounding the issues of OLED-related technology developments. From the middle of the 2000s, firm behaviors have focused on the acceleration of the existing technologies and the development of futuristic display. In other words, there has been competition to take leadership of the innovation in the level of final products such as the TV and smartphone by applying the display panel products. This study will provide not only better understanding on the context of the display industry, but also the analytical framework for the direction of the predictable innovation through analyzing the managerial and technological factors. Also, the methods can support CTOs and practitioners in the technology planning who should consider those factors in the process of decision making related to the strategic technology management and product development.

Recent international environmental regulations are focused on reducing pre-contamination and on sustainable development prior to the usage stage of a product. The Environmental Performance Declaration is being used as a tool for quantifying the environmental performance of products, to reduce contamination in advance, and for advertising the results of railway vehicles in Europe. In this study, a life cycle assessment of the tilting train was conducted, the first such case study in Korea, according to the ISO 14025 standard and Korea EDP (Environmental Declaration of the Product) rule. As a result of the LCA, the life cycle carbon emission of the tilting train was determined to be $3.54{\times}10^7kgCO_2eq.$ which is higher than that of a European train. Also, the amount of $CO_2$ emission of the Mcp and car body is higher than that of the other car and bogie.

In O2O environment(Online-to-Offline), providers attract new customers via web sites and lead them to pay online, then induce them again to offline when receiving products. Thus, online and offline channel is integrated and create synergy for marketing in O2O context. As online and offline channel coexist in O2O, consumers' perceptions for products and services that providers offer cannot help being different compared to an independent channel (i.e., either online or offline). Therefore, this research aims to develop the O2O service quality model(O2O-SQ model). Especially, O2O is the unique environment where offline, online, and mobile commerce are integrated so that the current paper suggests the $1^{st}$ O2O-SQ model by integrating the common factors of offline, online, and mobile service quality model through the previous literature review. Hence, this study conducts FGI(Focus Group Interview) for customers who have experienced in purchasing products in O2O commerce. Among integrated common service quality factors of $1^{st}$ O2O-SQ model, the current paper identifies the specific service quality factors that customers perceive significantly through FGI analysis. Moreover, after extracting the unique O2O-SQ factors with this qualitative analysis and integrating with the $1^{st}$ O2O-SQ model, the paper develops the final O2O-SQ model.

Firms that have adopted internet technology have been confused by distorted market signals. It is natural to look at marketplace outcomes for guidance, when confronted with a new business phenomenon. However, market signals can be unreliable in the early states of any important new information technology. New technologies trigger rampant experimentation, and the experimentation is often unsustainable. As a result, market behavior is distorted and must be interpreted cautiously. In Chapter 1, we review a concept of business model and roles of strategies in a business model. In Chapter 2, we discuss a strategic auditing method for analyzing market/channel positioning, product/service positioning, value chain/value network positioning and external environmental factors. In chapter 3, we introduces major frameworks for understanding factors forming strategies. The strategic grid model categorizes four quadrants depending on the level of impacts of information technology on operation and strategy. The strategic alignment model presents a new method of assessing an alignment of information technology and business throughout all elements of a business model. In this research, we review the concept of a business model. This research introduces factors that shape strategies and new frameworks for understanding these factors. The research objective of this manuscript is to present a guidance for firms how to use information technology for attaining sustainable competitive advantages.
