This study aims to elucidate the key improvements through the current state of customer support for smart home services based on the Internet of things and the evaluation of user's usage. Smart home services typically provide a wide range of value in terms of security, safety, manageability (electricity and water use), convenience, and remote management accessibility. In this study, we analyzed the current state of smart home service based on Internet of Samsung, SKT and LG U + companies in Korea. However, since LG U+ is the only company providing user reviews, there is a limit to generalization, but we are trying to figure out whether the customer value is conveyed properly or not, and in which part the customer support is focused to support the service. As a result of analyzing the results of the study, we found that the smart home service is commercialized and marketed in various forms. However, it is questionable whether the technological level and user satisfaction level are sufficiently satisfied. The results of this study are as follows. First, although each company provides usage guidance, they still ask many questions about joining products and using products. Second, there are many defects in the product itself, and it is found that the companies are not satisfied with the overall response. Third, the three companies are focusing on switches, outlets, sensors, and lamps. This is an individual intelligent product rather than an interlocking or linking level, and it can be seen that there are many parts that are not compatible with the concept of the original Internet of things. In conclusion, this study shows that there are still many areas to improve on the level of customer service provision of smart home service, in particular, the ease of use is low and the quality of products is not reliable. We would like to present the improvement of this in detail through this study and reflect the companies that provide it and the service providers.

Until recently, as we recognize the significance of sustainable growth and competitiveness of small-and-medium sized enterprises (SMEs), governmental support for tangible resources such as R&D, manpower, funds, etc. has been mainly provided. However, it is also true that the inefficiency of support systems such as underestimated or redundant support has been raised because there exist conflicting policies in terms of appropriateness, effectiveness and efficiency of business support. From the perspective of the government or a company, we believe that due to limited resources of SMEs technology development and capacity enhancement through collaboration with external sources is the basis for creating competitive advantage for companies, and also emphasize value creation activities for it. This is why value chain network analysis is necessary in order to analyze inter-company deal relationships from a series of value chains and visualize results through establishing knowledge ecosystems at the corporate level. There exist Technology Opportunity Discovery (TOD) system that provides information on relevant products or technology status of companies with patents through retrievals over patent, product, or company name, CRETOP and KISLINE which both allow to view company (financial) information and credit information, but there exists no online system that provides a list of similar (competitive) companies based on the analysis of value chain network or information on potential clients or demanders that can have business deals in future. Therefore, we focus on the "Value Chain Network System (VCNS)", a support partner for planning the corporate business strategy developed and managed by KISTI, and investigate the types of embedded network-based analysis modules, databases (D/Bs) to support them, and how to utilize the system efficiently. Further we explore the function of network visualization in intelligent value chain analysis system which becomes the core information to understand industrial structure ystem and to develop a company's new product development. In order for a company to have the competitive superiority over other companies, it is necessary to identify who are the competitors with patents or products currently being produced, and searching for similar companies or competitors by each type of industry is the key to securing competitiveness in the commercialization of the target company. In addition, transaction information, which becomes business activity between companies, plays an important role in providing information regarding potential customers when both parties enter similar fields together. Identifying a competitor at the enterprise or industry level by using a network map based on such inter-company sales information can be implemented as a core module of value chain analysis. The Value Chain Network System (VCNS) combines the concepts of value chain and industrial structure analysis with corporate information simply collected to date, so that it can grasp not only the market competition situation of individual companies but also the value chain relationship of a specific industry. Especially, it can be useful as an information analysis tool at the corporate level such as identification of industry structure, identification of competitor trends, analysis of competitors, locating suppliers (sellers) and demanders (buyers), industry trends by item, finding promising items, finding new entrants, finding core companies and items by value chain, and recognizing the patents with corresponding companies, etc. In addition, based on the objectivity and reliability of the analysis results from transaction deals information and financial data, it is expected that value chain network system will be utilized for various purposes such as information support for business evaluation, R&D decision support and mid-term or short-term demand forecasting, in particular to more than 15,000 member companies in Korea, employees in R&D service sectors government-funded research institutes and public organizations. In order to strengthen business competitiveness of companies, technology, patent and market information have been provided so far mainly by government agencies and private research-and-development service companies. This service has been presented in frames of patent analysis (mainly for rating, quantitative analysis) or market analysis (for market prediction and demand forecasting based on market reports). However, there was a limitation to solving the lack of information, which is one of the difficulties that firms in Korea often face in the stage of commercialization. In particular, it is much more difficult to obtain information about competitors and potential candidates. In this study, the real-time value chain analysis and visualization service module based on the proposed network map and the data in hands is compared with the expected market share, estimated sales volume, contact information (which implies potential suppliers for raw material / parts, and potential demanders for complete products / modules). In future research, we intend to carry out the in-depth research for further investigating the indices of competitive factors through participation of research subjects and newly developing competitive indices for competitors or substitute items, and to additively promoting with data mining techniques and algorithms for improving the performance of VCNS.

In the energy-climate era, pollution emissions from port activities have a significant issue in international shipping and port community. Thus international organization such as IMO and developed countries are seeking to develop various reduction strategies against air pollution. However Korea has recently conducted several studies concerning air pollution in port industry. The main purpose of the paper is to suggest emission reduction strategies for bulk terminal in Port of Incheon, which handles large amount bulk cargoes as a gateway for the metropolitan area. For this aim, the clean air strategies of the world major ports were considered and air pollution reduction strategies were suggested. The main findings of this paper are as follows. First, the emission reduction strategies for container terminal are should be integrated based on technologies changes, operational changes and market-based measures. Second, the emission reduction strategies for bulk terminal can be effective when use innovative measures during loading, unloading and storage process such as telescopic cascade trimming chute, snake sandwich equipment, dry fog system and dome structure. Finally, investigation on actual conditions of air pollution in Korean ports and development of environmental evaluation scheme for persisting monitoring should be conducted.

The channel of distribution exists for the purpose of moving product from the manufactuerer to the final consumer. In order to satisfy consumer needs, channels provide for the those products to arrive at the right place, at the right time and in the quantity, quality and price desired. Currently, there has been an emerging interest in the improvement of distribution system in many areas of industries and Korean government because of a market liberalizatiion begun at 1989 and still has processed step by step. In the wave of market liberalization, an understanding of the channel of distribution and structure would be very crucial when developing the opportunities of competitive advantages in Korean apparel industry. The purposes of this study were to investigate the determinants of the distribution channel and to identify how to respond to the market liberalization for developing the possible future strategies in the apparel industry. Data for this study were obtained from interviews with managers in apparel company in addition to a questionnaire mailed to over 106 middle management position of apparel company. Data were analyzed by using descriptive statistics. The results of this study were summarized as follows. 1. In the distribution channel of the apparel industry, a vertical marketing system, comprising producer, apparel company, retailer, prevailed without intermediaries such as wholesalers or vendors. Especially, the apparel company controlled marketing channel members. This type of system may reflect added product cost and may be not advantageous to retailers and consumers because most apparel companies are responsible for its own transfortation, storage and stocks after season. 2. In the view of market liberalization, most apparrel companies showed double-edged viewpoints. In terms of positive aspect, it would give stimulus to broaden variety of fashion merchandise and to improve product quality of fashion merchanise which were the most disadvantageous factors in competing with oversea's brands. In terms of negative aspect, it would bring the bankruptcy of small or medium sized apparel firms and the foreign products' penetration in domestic market. From this study, severel recommedations were suggested forward to improve the present condition in apparel industry. They included eliminating the power of apparel company and reinforcing middlemen for more efficient distribution system and for satisfying consumer needs in rapidly changing environment. Also it included government supports, reinforcement of information system, improvement in channel structure, and career development program in conjunction with apparel companies and academic society for improving scientific management and future potential strategies in Korean apparal industry.

Since the late 20th century, due to the globalization of markets and the rapid developments of information and communication technologies, the world has entered into the age of fierce competition. With their abundant low-cost labor, former communist countries such as China, Russia and East Europe and former low-developed countries such as India and Brazil have received foreign investments from major industrial companies. Thus, there are no other alternatives remained for Korea and OECD countries other than moving the industrial economies to the knowledge based innovation systems. In the knowledge based innovation systems, economic developments and employments of regions and nations depend solely on companies situated in their territories. In this article, after reviewing the current state of technological based innovation small firms in korea, we provide a theoretical framework to promote the level of technology based innovation and entrepreneurship. The theoretical framework for analysis and policy suggestions is based on the Schumpeter's value system model that consist of supply factors, demand factors, and supporting institutions. In order to create more innovative small businesses, we insist on the followings. First, more R&D and innovation activities related with promising new technologies should be performed. Second, more R&D funds for technological innovation small companies should be provided from governments. Third, more M&A transactions and technology transactions should be marketed freely and competitively. Fourth, more business incubating services and venture capital services should be provided. Fifth, entrepreneurship and innovation culture should be popular and institutionized among people.

Enterprises' participation in the collaboration research is one of the effective and typical methods through which technologies go into the market or are transferred to other sectors. This study reviews enterprises' participated collaboration research and analyzes their network for disaster and safety management area. From 2005 to 2016, 786 technical papers from four representative journals for disaster and safety management in Korea are compiled based on the authors whose affiliations are from enterprises. During the research period, collaboration research is found to be in an increasing trend in general. However, the number of technical papers with three or less authors is in a decreasing trend, whereas that with four or more authors is in an increasing trend. This fact implies that the range of enterprises' collaboration research is widening. Technical paper productivity and each entity's collaboration network are evaluated using participation-weight based author score. Over the research period, a few universities, which attract most of the enterprises, are found to have higher productivities and centralities. Public enterprises show higher participation weights. Also, sectors such as construction, engineering, and electronics demonstrate higher weights. This study is particularly meaningful because enterprises' participation status in collaboration research for disaster and safety management area is systematically analyzed for the first time in Korea. The network analysis result from this study will be especially helpful in establishing technology transfer strategy.

The dried root of Angelica species is used in traditional Chinese medicine in East Asia, particularly in Korea, China and Japan. Since the plant origin differs in these countries, they are often misused or adulterated in the commercial markets, resulting in distrust among the consumers. Enormous efforts have therefore been focused to distinguish the origin for the Angelica genus, by using morphological or cytogenetical analyses, and chemical markers based on biochemical analyses of secondary metabolites. DNA is considerably stable against different cultivation conditions, and to treatment and processing after harvesting of plants. Hence, several researches have been filed for the development of molecular markers, based on the single nucleotide polymorphisms in specific regions of DNA. However, there are several obstacles for application in the commercial markets, concerning the reproducibility, accuracy, sensitivity, and rapidity of these tests. In this review, we summarize the research achievements that help classify the origin of Angelica species, in particular, Angelica gigas Nakai. A. sinensis(oliv.) Diels, A. acutiloba Kitag., and A. acutiloba var. sugiyamae Hikino. Further researches are required for practical applications.

현재 인류가 직면한 에너지 부문의 큰 난제는 화석연료의 한정된 매장이기도 하지만 그 사용에 따른 환경오염으로 인한 피해들이 더 큰 문제로 대두되고 있다. 그중 지구 온난화의 영향으로 최근 세계에 국지적인 홍수, 가뭄, 태풍등의 기후 불안정으로 피해보는 상황이 가속화 되고 있다. 또한, 북극지방의 해빙으로 해수면 상승이 예상되며 머지않은 시간에 해수면 상승의 직접적인 피해가 인류에게 오리라는 보고가 많이 발표되고 있다. 그런데 우리가 더욱 중요한 것은 지구촌83의 관성이 크기 때문에 지구 온난화 와 해수면 상승이 인류에 큰 피해를 미치기 시작할 때는 이미 돌이킬 수 없는 상황에 진입해버린다는 사실을 간과하고 있는다는 것이다. 그러므로 과학적 분석에 근거하여 피해를 축소하기위한 활동을 실천해야할 시기이다. 특히, 우리나라의 경우 에너지의 97% 이상을 해외에서 수입하고 있으며, 세계에너지 소비 10위, 석유 소비 7위의 열악한 에너지 자원 빈국인 만큼, 중장기적인 관점에서 석유의존도를 개선하고 신재생에너지원을 확보하는 등 대책마련이 시급한 실정이다. 신재생에너지원으로 현재까지 가장 큰 역할을 해왔던 것 중의 하나가 풍력발전기인데, 오늘날 세계 풍력에 의한 발전량은 세계 총 발전량의 2% 미만에 불과하이다. 이러한 풍력 시장에 발맞춰 국내에서도 풍력발전기 개발에 많은 힘을 쏟고 있는데, 2002년부터 750 kW급 풍력발전기가 처음 개발되기 시작하였고, 이후 2 MW급 풍력발전기와 3 MW급 풍력발전기가 개발되었으며, 최근에는 5 MW와 7.5 MW급등 초대형 풍력발전기가 대기업 중심으로 개발 진행되고 있었으나, 2008년 세계 금융위기 이후 세계 경기침체의 영향으로 국내 풍력산업도 적지않은 영향으로 구조조정되어 기존 7~8개 풍력발전기 제조사들이 3개사 이하로 축소되고 있다. 이에 정부 및 전라남도는 해상풍력산업을 침체기를 겪는 조선산업의 대체산업으로 육성하기위해, 정부 주도로 부안 앞바다에 2.5 GW 해상풍력발전단지개발을 준비 중에 있으며, 전라남도는 전남 서해안에 4 GW 해상풍력발전단지 개발을 서두드고 있다. 특히, 전라남도는 국내에서 가장 많은 풍력에너지 포텐셜을 가지고 있으며, 바람의 질 또한 우수하여 이를 지역산업 활성화의 모멘텀으로 가져가기위해 많은 노력을 기울이고 있다. 그 일례로 영광군 백수읍 하사리 바닷가 $4,342m^2$ 부지에 "풍력테스트베드"를 개발하여 국내 풍력발전기 제조사들이 활용하도록 도움을 주고 있다. 종래의 테스트베드는 해외지역을 이용하였는데, 이는 국내에서 개발된 풍력발전기들이 국제인증을 받기위해 바람의 질이 좋은 해외 테스트베드에 설치되어 평가받았으며 고가의 비용이 소모되었다. 제주도에 테스트베드 장소가 있긴 하지만 수용 규모가 작아 풍력발전기 제조사들이 대기할 수 없어 해외로 나가는 실정에 전라남도의 내륙 테스트베드를 개발함으로서 풍력발전기 제조사들에게 큰 도움을 주고 있다. 본 보고에서는 국가 해상풍력 산업발전의 단계별 전략과 전라남도의 해상풍력산업의 방향 그리고 풍력테스트베드의 현황을 소개하고자 한다.
