The main aim of this study is a meta-theoretical investigation to explain the current theoretical landscape of social innovation theories and researches. First of all, this paper makes a typology of social innovation based on concepts and sectors of social innovation. Second, in terms of societal innovation, which it is a kind of social innovation systematic approach, this paper draws some implications for social innovation policy. My key argument is that social innovation could be specified in three different sectors, public innovation, market innovation, and social economy innovation. However, all of them have attention to such as improving a quality of life and making society more sustainable, so it can be argued that those different sectors are structured on social innovation altogether with common goals. Finally, in order to activate the social innovation ecosystem, the government has to play a key role as a facilitator to make sustainable networks and a governance of social innovation that is needed to coordinate between different features and roles of social innovation sectors.

This study is to diagnose the tourism structure of the southern region in Kangwon province and to correct the problems regarding the subject. The methods of comparison and analysis on structural and geographical characteristics of tourists, tourism resources, and tourism industry by region have been employed. It was found that the southern region of Kangwon province has many advantages for tourism industry including excellent transportation networks such as Kangnws and Wonju and tourism demands are great for coal mines in the region including Chongson, Taebaek, and Samchok. Accordingly, tourism in the region has witnessed a distinctive increase in recent years. On the other hand, excessive dependence on nature-based tourism, concentration of tourism demands only during summer season, and insufficient tourism facilities are found to be problems. This study also found that for sustainable tourism developments in the southern region of Kangwon, categorization and diversification of tourism resources, development of combined programs connecting Kangwon province to other regions, improvement of tourism facilities, expansion of tourism market, and smaller division of tourism area are necessary.

Geographic information system (GIS) based renewable energy resource map including potential analysis can play a crucial role not only to develop the national plan for renewable energy deployment but also to make strategic investment decision in the private sector. Korea Institute of Energy Research (KIER) has been developing domestic maps about several resources such as solar, wind, hydro, biomass, and geothermal, as well as conducting research on methodologies for potential analysis. Furthermore, the institute is trying to transfer related technologies and know-how to foreign countries, recently. In this context, the main purpose of this study is to introduce the business model of renewable energy resource map. From the value chain analysis, we focus on the government-side market in foreign countries, such as the development of the national level renewable energy resource map and the support of the national renewable energy plan. For about 180 countries, we segment the customers according to the consideration of economic capacity, renewable energy resource capacity, existence of renewable resource map, current portion of renewable energy facility capacity, and renewable energy policies, and we conclude that the target customers are non-Organization for Economic Co-operation and Development (non-OECD) countries or some OECD countries, their per capita GDP are under the average among OECD countries, that do not have renewable resource map yet. We segment the target customers into four groups, and suggest different strategies for market positioning and financing strategy based on Strengths, Weaknesses, Opportunities, Threats (SWOT) analysis. This study can help to develop the business strategy about the development of renewable energy resource map in foreign countries.

The k-means clustering algorithm groups input data with the number of groups represented by variable k. In fact, this algorithm is particularly useful in market segmentation and medical research, suggesting its wide applicability. In this paper, we propose a privacy-preserving clustering algorithm that is appropriate for outsourced encrypted data, while exposing no information about the input data itself. Notably, our proposed model facilitates encryption of all data, which is a large advantage over existing privacy-preserving clustering algorithms which rely on multi-party computation over plaintext data stored on several servers. Our approach compares homomorphically encrypted ciphertexts to measure the distance between input data. Finally, we theoretically prove that our scheme guarantees the security of input data during computation, and also evaluate our communication and computation complexity in detail.

This paper is a study on the development and consumer preference of the soup stew HMR new products, and the main contents are as follows. A total of nine products were studied, including three developed products and six market products. For this study, the demographic characteristics, the awareness and attitude of HMR products were investigated. In addition, the consumer panel evaluated overall liking, appearance, color, flavor, and taste using the nine-point recertification scale, while the strength assessed viscosity, sweetness, saltiness, sourness, and Umami. Familiarity, health degree, Purchase intention and Recommendation intention were investigated and the reasons for preference and non preference were analyzed by multi-response method. The consumer preference analysis indicates that the product is competitive among existing products and that it would be desirable to improve after identifying the causes of non-preferred factors.

With the increase of single households and more women entering society, changes to lifestyle, a demand for convenience, and the recent trend for homemade meals, the market for HMR(Home Meal Replacements) is rapidly growing. This study reviewed the repurchase intentions of consumers for RTP(Ready-to-Prepare) HMR products, namely meal kits, and the moderating effect. The study found that i) ease of use increases with higher self-efficacy; ii) ease of use decreases with higher personal innovativeness, but usefulness and repurchase intentions increased; iii) repurchase intentions increase with higher social influence; iv) trust decreases with higher convenience, but repurchase intentions increased; v) trust and repurchase intentions increase with higher economic efficiency; and vi) price sensitivity has a moderating effect between trust and repurchase intentions. The outcomes of this study will not only provide a theoretical basis for a more detailed study of HMR, but is anticipated to be used as fundamental data for suggesting a direction for marketing strategies for product development and sales.

The ocean is a unique space for exchange with the city, forming an organic relationship between people and waterfront areas. The marine healing industry improves quality of life through medical care and well-being, and creates added value by combining with the medical industry. The policy analysis results are as follows. First, the marine healing industry is the newest high-growth area. Furthermore, a professional medical service hospital is the first priority. This will include the development of marine healing facilities and strengthening forest healing connectivity, emphasizing the development of highly specialized medical technologies. The second priority is value creation in marine healing specialization, accompanied by an integrated and systematic policy for research and development of new medicines in marine healing effects. It is also important to apply new market trends and develop applied marine healing service programs. Thirdly, it is necessary to explore the possibility of a fragmented market for policy development.

기업신용평가(ICR : Issuer Credit Rating)는 기업의 금융상 채무에 대한 전반적인 적기 상환능력, 즉 채무불이행의 가능성을 평가한 것으로 오로지 금융상 채무에 대한 전반적인 채무상환능력을 평가한다. 최근에는 신용평가 등급이 금융시장과의 효과적인 의사소통수단으로 인식되고 기업 IR 및 홍보차원과 기업 간 물품공급과 납품을 위한 업체 선정시 신용등급이 적극적이고 다양하게 활용되고 있다. 이러한 기업신용평가는 최근 경제환경의 급속한 변화에 대응하여 기관별로 평가시스템을 자주 개선하고 있다. 본 연구에서는 정책금융기관 별로 변화된 평가시스템에 대한 평가지표나 구조, 평가시스템을 비교 분석해 그 차이점과 공통점 그리고 경제환경 변화에 따라 변화된 주요지표를 파악해 보고 미래의 신용평가시스템의 변화와 개선방안에 대해 생각하였다. 기관별 비교에서 평가시스템의 차이점은 신보는 신용평가(부실률 기반)와 미래성장성평가(성장성 기반)를 실시하여 보증심사등급(보증의사결정 등급)을 산출하고, 기술자산평가등급은 신용평가등급을 조정(최대 ${\pm}2$등급)하는 보조적 수단으로 활용하고 있으며, 기보는 기술평가(성장성 및 부실률 기반)와 리스크관리용 리스크평가(신보의 신용평가에 해당)로 평가체계를 이원화하여 운영하고, 평가모형은 신보는 객관성을 확보한 정량평가 위주, 기보는 공신력을 확보한 정성평가 위주의 주관적인 평가를 실시하고 있어 어떤 형태의 평가시스템이 더 좋은 평가방법 인지는 알 수 없지만, 기관별 부실율을 보면 다소 참고가 될 수도 있으나, 이것이 전적인 평가의 문제라 보기도 어렵다. 특히 신보는 창업기업 기준이 창업후 7년까지로 확대됨에 따른 창업 3단계 평가제도와 기업의 성장단계에 맞춘 성장단계별 평가기준 세분화는 기업환경을 잘 반영한 변화라 볼 수 있다. 그리고 향후 평가시스템은 경제환경의 변화속도를 어떻게 잘 반영 할 수 있는지에 대한 연구로 방향이 전개될 것으로 보인다.

This study investigates the effects of venture capital investment and corporate venture capital investment on the performance of IPOs listed on KOSDAQ between 2000 and 2014. We classified venture firms with venture capital-backed companies and non-venture capital-backed companies, having the former of which further divided into corporate venture capital-backed companies and independent venture capital-backed companies. The time window of the analysis was set to between 2 years before and 3 years after IPO. Main results of this study reveal that there is little difference between venture capital-backed companies and non-venture capital-backed companies in terms of profitability before and after going public. However, we found out that after IPO venture capital-backed companies display higher ROA than independent venture capital-backed companies or non-venture capital-backed companies, suggesting that corporate venture capital-backed companies might be more advantageous in growing a venture capital ecosystem in Korea.

In order to continue to grow in response to the rapidly changing industrial environments, companies must retain technological innovation capabilities and enhance market competitiveness. When competition is intensifying for creating new businesses and developing new products through technology commercialization, creating and utilizing technology convergence performance is an important means to create new competitiveness. However, there has been a lack of effort to systematically understand the level of technology convergence performance of the enterprise and to understand its relationship with management performance. In this paper, we develop a new analytical index by segmenting the technology convergence into patent variety, balance and disparity using patented IPC code information based on the concepts presented in existing diversity studies. In addition, 4,522 patents granted for three years between 2013 and 2015 by 219 KOSDAQ companies belonging to the domestic ICT convergence industry were analyzed to demonstrate that the level of technology convergence performance is positively related to sales growth rate in 2016.
