Research on consumers' perception and willingness to purchase Battery Electric Vehicles (BEVs) is necessary to simulate BEVs' deployment in South Korea because South Korea's BEVs market is still in the early stage. This paper derives a theoretical framework for consumer segmentation based on consumers' willingness to purchase before and after BEV usage experience. In particular, this study empirically evaluates consumers' willingness to purchase and concerns using the survey data from BEVs users in either Seoul or the Jeju region. The empirical results from logit models show that experienced consumers' concerns about the heater and air conditioning (HAC) in BEVs decreased the consumers' willingness to buy, while greater daily driving distances increased the consumers' willingness to buy. In addition, the empirical findings from ordered probit models show that experienced consumers' concerns about the short driving distance, the availability of maintenance service (i.e., A/S service) during unexpected events, and the difficulties of driving BEVs up-hill increased the degree of concern about HAC. This paper will provide insights related to consumer segmentation, R&D, marketing strategies, and policy design for policymakers and firms.

This study examines the usage status of legal services provided by lawyers targeting domestic consumers and investigates empirically how much online platforms that facilitate lawyer search and consultation can increase consumers' utility, and how much the lawyer legal service market will expand through this. To this end, this study applies a discrete choice demand model to the data collected through a conjoint survey to estimate the value of the lawyer search and consultation platform perceived by consumers, and estimates the effectiveness of the platform in expanding the market for lawyer legal services through a simulation method. As a result of the analysis, the relative value that consumers place on finding and consulting a lawyer using the online platform instead of being introduced to a lawyer by an acquaintance or searching for a lawyer offline is estimated to be about 70,414 won. It was found that the existence of lawyer search and consultation platforms could increase the market size of legal services by as little as 18.9% to as much as 70.2%. In particular, the platforms are expected to increase the accessibility of legal services to vulnerable groups.

This paper provides a new method of measuring the degree of technological progress which contributes to real economic growth based on Schumpeter's Trilogy. Using Microdata of Statistics Korea, the results of measuring and comparing the actual growth contribution of technological progress during the period 2003-2018 by the total factor productivity growth rate(growth accounting method), the R&D investment contribution rate, and the Schumpeterian innovation growth rate, respectively are as follows. First, the measurement of the real growth contribution of technological progress by the growth rate of total factor productivity and the growth rate of Schumpeterian innovation shows contradictory results. Second, when the growth rate of production is in a decreasing trend, the difference between the growth rate of production and the growth rate of total factor productivity increases compared to when it is in an increasing trend. Conversely, when there is an increasing trend, the difference between the growth rate of production and the growth rate of total factor productivity becomes smaller compared to when it is in a decreasing trend.. Third, the technological opportunity that affects the innovation growth rate, i.e., the contribution of R&D incentives to innovative growth is only 3.3%. The reason why this result is different from the existing perception of the contribution of technological progress to growth is that different entities are being measured while measuring the same term of technological progress. Therefore, the growth rate of total factor productivity should be used to measure macroeconomic efficiency, R&D investment should be used to measure the effectiveness of new technology supply, and the Schumpeterian innovation rate should be used to measure the economic impact of technological progress. The policy implications of the research results of this thesis are as follows: ① Transition from a policy of one-sided technology supply to a policy of convergence of technology supply and new technology demand support, ② Mission-oriented R&D policy and R&D policy that links national R&D with private R&D, ③ Reclassification of capital goods reflecting the degree of new knowledge.

Linear regression technique has been used widely in water resources field as well as various fields such as economics and statistics, and so on. Using fuzzy regression technique, it is possible to quantify uncertainty and reflect them to the regression model. In this study, fuzzy regression model is developed to compute design floods in any place in Pyeongchang River basin. In ungaged basins, it is usually difficult to obtain data required for flood discharge analysis. In this study, basin characteristics elements are analyzed spatially using GIS and the technique of estimating design flood in ungaged mountainous basin is studied based on the result. Fuzzy regression technique is applied to Pyeongchang River basin which has mountainous basin characteristics and well collected rainfall and runoff data through IHP test basin project. Fuzzy design flood estimation equations are developed using the basin characteristics elements for Pyeongchang River basin. The suitability of developed fuzzy equations are examined by comparing the results with design floods computed in 9 locations along the river. Using regional regression method and fuzzy regression analysis, the uncertainties of the design floods occurred from the data monitoring can be quantified.

The major purposes of the research are to see the underlying disciplines of technology innovation management which contribute to Korean research. To do that, we employed author cocitation analysis which has been proved to be robust. We compiled all the citations of two major Korean journals between 1993 and 2006. We also included up to 3rd author, which makes a cocitation analysis more comprehensive, compared with the previous analysis for the first author only. We identified 239 authors who have more than 10 citations. From the cocitation combinations based on the 239 authors, we selected and analyzed 100 most cocited authors. Out of 100 authors a group of 23 authors who command both higher citations and cocitations were chosen for detailed analysis. The results show that the average number of publications is 22.2, the average number of citations to them is 58.5, and the average number of citations to a publication is 2.6. Also, the average number of cocitations is around 10 times that of citations. The results indicate that there are six major disciplines: Technology/Innovation, Management of Technology, Economics of Technology, Development, Valuation of Technology, and Growth. Noteworthy points are the following. 1) Most of the members of the technology management group are management scholars, and the groups of economics of technology and growth are economists, while the groups of technology innovation and development group are not represented by specific disciplines. 2) Considering the groups overall from the traditional academic disciplines, the main branches are management and economics. 3) The valuation of technology group consists mostly of Korean researchers.

배경 : 의과학과 사회-경제학의 발전은 인간 수명 연장에 지대한 공헌을 해 왔다. 그러나 결과적으로 피부 질환으로 고생하는 노인 인구도 증가하였다. 본 연구에서는 동국대학교 한방 안이비인후피부과에 피부질환을 주소증으로 내원한 성인 환자들을 대상으로 임상 양상을 조사해 보고 고령사회에서 어떻게 한방 피부과 의료 수요 변화에 대처하고 발전해 나아갈 수 있을지 그 방법을 모색해 볼 수 있는 근거 자료로 활용하기 위해 수행하였다. 연구방법 : 2002년 1월부터 2004년 12월 까지 3년 동안 동국대학교 한방 안이비인후피부과에 피부 질환을 주소증으로 내원한 319명의 환자를 대상으로 하였다. 그들을 내원시기, 연령, 성별로 나누어 질환별 분포를 조사하였다. 통계분석은 $X^2$ test(Window, SPSS 11.0)를 사용하였고 p <.05를 유의수준으로 하였다. 결과 : 2002년부터 2004년 까지 질환별 분포를 살펴보면 습진 21.9%, 소양증 20.4%. 여드름 16.9%,로 나타났다. 2002년에는 습진 17.0%, 소양증 16.0%, 여드름이 14.9%였다. 2003년에는 소양증 34.2%, 두드러기가 23,3%, 습진이 17.1%였다. 2004년에는 습진 61.4%, 여드름 21.1%, 소양증 15.8%였다. 이들 결과는 통계적으로 유의한 차이를 보였다($X^2\;=\;54.135^{***}$, p = .000, df : 20). 남자에서는 습진이 25.0%로 가장 많았고 소양증 19.5%, 두드러기 12.5%, 지루성 피부염 11.7%로 나타났다. 여자에서는 여드름이 22.0%로 가장 많았고 소양증 20.9%, 습진 19.9%였다. 이들 결과는 통계적으로 유의한 차이를 보였다($X^2\;=\;19.839^*$, p = .031, df : 10). 20대 환자에서는 여드름이 24.1%로 가장 많았고 습진과 소양증이 각각 19.5%였다. 30대 환자군에서는 습진이 30.3%였고 소양증이 19.1%였다. 40대에서는 소양증이 28.8%였고 지루성 피부염이 16.0%였다. 50대에서는 습진이 26.7%였고 60세 이상의 그룹에서는 습진이 50.0%, 바이러스 질환과 소양증이 각각 15.0%였다. 이들 결과는 통계적으로 유의한 차이를 보였다($X^2\;=\;74.995^{**}$, p = .001, df : 40). 결론 : 상대적으로 50세 이상 연령충의 대상 환자 수가 많지 않은 원인은 여리 가지 분석이 가능할 것으로 생각된다. 연령에 따라 피부질환이 다른 양상을 보임을 고려할 때 노인층의 신체적, 경제적, 사회적 특성을 이해하고 이에 따른 효과적이고 사회-경제학적 부담을 최소할 수 있는 한방 치료 영역의 확대 및 개발이 필요할 것으로 사려된다.

This article focuses on geo-institutional differentiation and a multi-scalar analysis of emerging capitalist development in Laos. It discusses the impact of the Greater Mekong Subregion on new institutional economic and economic geographical arrangements. It demonstrates the usefulness of the varieties of Asian capitalism approach. The rubber industry was chosen to unravel emerging but various sub-national institutional arrangements linked to higher scale levels. Rubber is a growing agribusiness industry throughout the country, led by the insatiable demand from China. Overall, this study shows that the capitalist development of the rubber industry features much geo-institutional differentiation, due to the different strategies of Chinese, Thai and Vietnamese investors. Since Laos is still in transition from a state-led economy to something else, it is impossible at this to identify the exact number capitalisms. Yet, the evidence on rubber clearly lays bare the presence of multiple institutional arrangements. Without more inclusiveness, however, the implications for regional development are worrying. Exclusive arrangements will most likely lead to more uneven regional development and higher regional inequality. To refine theories on sub-national varieties of capitalism in developing countries it is instructive to consider more explicitly the notion of regional personal capitalisms and the complex interplay between national and regional states and relationships between capital accumulation and livelihood analyses.

The purpose of this study is to identify key factors of Co-opetition through examining the environmental and structural changes in the ports industry and suggest a few Co-opetition strategies for enhancing our ports capabilities in the long-term. In recent years, the trend toward market liberalization and globalization in ports industry has made rapid progress and it made the competition fiercer. To survive in this rapid changes, the ports have traditionally pursed a competitive strategy. However, an alternative strategy replacing the traditional strategy was introduced: namely, 'Co-opetition' a buzzword combining competition and co operation. Policy proposals this study suggests are the construction of a database regarding costs and benefits of ports for more effective analysis and improving the competitive power of a shipping company operating national flag carriers for achieving the purpose of Co-opetition and adoption of selection and concentration strategy for increasing the possibility of Co-opetition success.

This Study has two research interests: First, to give a new perspective in searching for the identifying features of social welfare studies in Korea where social welfare is recognized as an independent discipline through an examination of german research trends in social policy, where social policy is not recognized as an independent discipline, but as a field of study. The reasons of non-recognition of social policy studies as an independent discipline in Germany are value problems, vagueness of research objects, and the position of social welfare in relation to another social sciences. Second, to show the trends of german studies in social policy from diverse disciplines, i. e. sociology, political science, law, history, pedagogics etc. and the common points in these studies. The results of this study are as follows. First, the common feature of german Studies on the social policy from diverse disciplins is above all the interest in the improvement of Lebenslage, i. e. conditions of life. Second, the value problems in social sciences are not solved till now, but the interests in the improvement of Lebenslage don't mean studies of social policy must handle with values. The interests in the applicability of social policy don't mean values must be improved in the studies either. Third, the vagueness of the objects can be found also in other social sciences and is not unique in social policy studies. Fourth, the studies, which focuses on the improvement of Lebenslage and can contribute to construct theories such as raising the effectiveness of state intervention must be recognized as studies of social policy, even though they are written by social scientists from other disciplines. This means the theories of social policy to pursue are connected with theories of middle range, i. e. with lower degree of abstraction.
