  • 유속계수는 상수도 설계, 운영, 유지관리 등의 과정에서 항상 현장 실정이 고려된 값이 사용되어야 한다. 본 연구는 광역상수도 정밀안전진단 과정에서의 174개 실측자료를 바탕으로 유속계수와 주요 인자 간의 관계를 통계적 기법을 활용하여 분석하였다. 이들 관계를 분석하기 위해서 교차분석, 일원배치 분산분석, 상관분석 등을 수행하였으며, 그 결과 유속계수와 사용년수 및 관경이 높은 상관관계를 나타내고 여러 범주형 자료 형태 영향인자 중에 내부도장재가 상대적으로 유속계수에 많은 영향을 주는 것으로 검토되었다. 반면 다중회귀분석의 결과에서는 사용년수, 관경 및 수종이 중요한 영향인자인 것으로 검토되었다. 군집분석 결과, 유속계수는 기본적으로 사용년수 약 20년, 관경 1500mm를 기준으로 분류되는 경향이 있었으며, 유속계수는 전반적으로 사용년수에 많은 영향은 받으나 대구경 관에서는 상대적으로 사용년수보다 관경에 많은 영향을 받는 것으로 검토되었다. 마지막으로 본 연구에서는 회귀분석과 군집분석을 사용하여 유속계수 산정식들을 제안하였으며, 이러한 추정식들은 추후 광역상수도의 유속계수 결정 및 사용 시에 판단기준이 될 수 있을 것으로 판단된다.

  • Objectives : When sweating factor is excluded, to know the influence of acupuncture stimulation on electrical resistance. Methods : Regional anaesthesia(Lidocane 2%, 1ml, Subcutaneous injection) is applied to measured regions, 4cm round area including left Neiguan P6. So we can make adiaphoresis. Before and after acupucnture stimulation to Laogong P8, we measured the electrical resistance of anesthetized left Neiguan P6, anesthetized non-acupoint, normal left Ximen P4, and normal right Neiguan P6. For measurment, we use the 1.2V, DC system that has 100$k{\Omega}$ internal resistance Results : Under the adiaphoresis, Acupuncture stimulation makes the significant decrease of electrical resistance. In normal regions, so does it. Conclusions : When the acupuncture stimulation is applied to human boby, the decrease of electrical resistance is due not only to sweat secretion but also to other internal resistance.

  • The present study construct a new technique that can evaluate diverse rural policies, which have been applied to the rural development programs at the village level. The method incorporates spatial econometrics models with a decomposition method that has little been utilized before. We applies the technique to evaluate the rural development programs that have been carried out by the Korea Forest Service and. Korea Rural Development Agency. The technique proved to be quite useful in that the technique efficiently separate the direct effect caused by the government policy from the effect explained by the endowment effect such as regional or area characteristics, and residual effect that cannot be identified by the models. The present study concludes with suggesting more quantitative methods need to be developed to evaluate diverse government policy programs, which enables us to discern correct policy effects.

  • This study aims to explore and understand the role of return migrants in the regional innovation system of a transition economy (China) by analyzing the activities of returning entrepreneurs in two emerging high-tech industries in Shanghai. The empirical analysis is based on in-depth interviews with founders of high-tech companies and experts in Shanghai. The results of the analysis reveal that return migrants are a significant factor for the Shanghai innovation system, which is presently in a transition from a former manufacturing site to a metropolitan region comprising a range of industries (including high-tech) and services. First of all, return migrants are important for the Shanghai RIS in terms of numbers. Second, they engage in activities in the medium range of high-tech which reflects prevailing weaknesses of the framework conditions for innovation in Shanghai. However, due to their international background, returning entrepreneurs are able to overcome these weaknesses, and thus contribute to the development of high-tech industries in Shanghai and to a reduction of the technological lock-in.

  • Competitiveness strategies has been associated in the tourism literature as a crucial factor for the success of tourist. The study aims to explore the competitiveness strategies for tourism destinations by conducting in-depth interviews with probe questions. Thirteen community enterprises' managers in rural tourism communities were interviewed with a semi-structured interview questionnaire for one or two hours. From the interview data, eight themes in two dimensions were identified as competitiveness strategies of rural community enterprises in rural Korea. Differentiation strategies consist of new product development, service improvement, brand image improvement, advertise and public relation, and concentration. Cost leadership dimension includes cost reduction, increasing benefit, and long-term investment. The findings of this paper implicate the underlying the competitiveness strategies from managers' perspective.

  • This study was to investigate if there are important variables of rural tourism destination for foreign tourists that discriminate rural tourism perception, experience, and intention to behavior. of the experience activity among the regions and the villages. From the literature review, the survey questionnaires was developed to measure important variables of rural tourism destination, rural tourism perception, experiences and intention to behavior. A total of 799 useful samples were collected and analyzed in SPSS. Factor analysis showed that there are four underlying dimensions (program, preparation to receive, service and regional products, and human service). the results of discriminate analysis showed that service and regional products are important variables in rural tourism perception and experiences. And also service and regional products and human service are important variables in intention to behavior. More detailed discussion and implications are provided in conclusion.

  • The Regional Comprehensive Economic Partnership (RCEP) agreement, signed in November 2020, comes shortly after the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) entered into force and the US-China Trade War escalated. We use a computable general equilibrium model to assess the long-term effects of these three developments on income, trade, economic structure, factor returns and employment across the world, and especially in Asia-Pacific countries. The results suggest that RCEP could generate income gains that will be almost twice as large as those of the CPTPP, and that the two agreements together will largely offset the substantial negative effects of the US-China Trade War for the world as a whole. All three policy developments, but especially RCEP, will deepen East Asian production networks and will raise productivity and increase wages and employment in much of East Asia. At the sectoral level, regional trade in non-durable and durable manufactures will experience the most growth.

  • Northeast Asian relations have been dominated by competitions rather than cooperation. Nevertheless, since the end of the Cold War, interchanges among South Korea, China, and Japan's local governments have been increasing rapidly. Why local governments of the three Northeast Asian states have maintained constant exchanges despite the sluggish cooperation of their central governments? What effects and limitations of exchanges among local governments in Northeast Asia on regional peace? The results of research show that effects of Northeast Asian local governments on regional peace is complicated. The study indicated that the local governments' exchanges had certain limitations in constructing the regional peace as an independent factor. However, it is also certain that the local governments' exchanges have contributed to the Northeast Asian peace, to some extent, by playing a complementary role in maintaining cooperation in local level.

  • The main goal of this study is to examine the competition intensity in the Korean bakery franchise industry and to identify the core competencies of the industry's leading company, Paris Baguette. The frameworks of PEST analysis, Cross Impact analysis, a Five Forces Model, a Value Chain, and VRIO analysis. PEST and Cross Impact analysis were employed to investigate the industry's external environment, and the results indicated that 'increased attention on corporate's Creating Shared Value (CSV) activities' is the most influential factor among others. The analysis using the Five Forces Model found industry rivalry and substitutes were the greatest threats. Finally, the results of Value Chain and VRIO analysis identified four core competencies of Paris Baguette: its CEO's craftsmanship, e-procurement system, quality of dormant dough, and hub system. Multiple managerial implications are suggested for practitioners in the marketing area, especially in the saturated market environment.
