Modern society is an era that demands higher standards of living, and accordingly healthier living conditions due to fast economic growth. This society is being confronted by the necessity to find strategies to promote and manage health condition in everyday living environment. The current 'wellbeing' trend which pursues holistic health including physical, psychological and social health has accelerated the demand for healthy environment. In this context, this study intended to identify health friendly planning features based on consumer's demand. Web survey technique was used as main research methodology. Stratified random sampling was used with age being used as the strata valuable. Two hundred and eleven data were analyzed using SPSS statistical package. As results, awareness about health housing and hierarchy of important planning features were empirically identified. Furthermore, significant differences in some planning features according to the age were scrutinized. Major health friendly features demanded by consumers were found ventilation, non-toxic material, view of nature, space in which family can gather, protection of their privacy. Consumers' recognitions and demands varied according to age. The older the resident was, the higher the demands appeared. The results are expected to be used as a reference to explore and develop strategies for future healthy housing.

The products of the quality certificated fisheries which are protected from environmental pollution, decomposition are hygienically safe and convenient for food. However, consumers have not yet understood the recognition of the system of quality certfication so far because of lack of demand on the quality certification fisheries. Above all, to put the system of the quality QC in place sucessfully, to understand the variation of consumer's inclination efficiently, the empirical study must be carried out by both consumer's take part in the market of the quality certificated fisheries products and how much the amount of consumption is in this market. The purpose of this study, under the preconditions where these have limited fisheries items in consumer's inclination survey, is to analyze the demand of QC though the Double Hurdle Model. Explanatory variables included were household characteristics such as housewives' age and education, her job, household income as well as their health perceptions and food purchase behaviors. Survey from 530 household was collected in Pusan City in 2003, of 502 were actually used for empirical analysis. The Double-hurdle framework proved to a better representation of the factors influencing the separate decision participation and consumption levels. According to the results of this study, whether or not, participating In the market of quality certicipating in the market of qualify certificated fisheries products is affected by how much experience and confidence these have got. housewives' having a job or not. Furthermore, the amount of consumption is mostly affected income. This value is attributed to the safety of QC fisheries products in comparison with regular fisheries. Findings suggest that the consumers put substantially high monetary value on safe food, such as high quality fisheries products. Therefore, first of all, legal and institutional systems should be clearly and strictly identified for the QC products.

Purpose - This paper empirically investigates the competition effect of exports between Korea and China in their common-export markets considering market sophistication. Modern market sophistication includes an importing country's aggregate demand for products of high quality, design, novelty, eco-friendliness, and even IPR protection. Using an empirical analysis to identify the demand for product quality across countries, this paper estimates the effects of market sophistication on the competition between Korean exports and Chinese products. Design/Methodology - Our empirical model considers the relationship between an importing country's consumer sophistication and the export competition between Korea and China. This study employs the existing theoretical framework to identify the aggregate demand for product quality across countries. Using a quite direct measurement (the consumer sophistication index, our analysis investigates the differential effects of Korea's export market sophistication, particularly in markets where Korean exports are in competition with similar Chinese products. Findings - Our main findings can be summarized as follows: the negative effects of the export competition between Korea and China on Korea's exports are stronger in third markets where consumers are less sophisticated while the effects are not as pronounced in markets where consumers are more sophisticated. This result, however, best applies to differentiated goods which significantly vary in product quality. Originality/value - Existing studies focus on the supply side of production and make the assumption that the market preference for export quality is identical across countries. This paper attempts to evaluate the export competition between Korea and China from the demand-side perspective. This area of trade studies is underexplored both empirically and in theory, although the issue has long been important to Korean and world trade.

As the importance of time-based competition is increasing, information systems for supporting the immediate decision making is strongly required. Especially high -tech product firms are under extreme pressure of rapid response to the demand side due to relatively short life cycle of the product. Therefore, the objective of our research is proposing a framework of estimating demand curve based on e-auction data, which is extremely easy to access and well reflect the limited demand curve in that channel. Firstly, we identify the advantages of using e-auction data for full demand curve estimation and then verify it using Agent-Eased-Modeling and Tobin's censored regression model.

Studies on the development of various energy management programs and real-time bidirectional information infrastructures have been actively conducted to promote the reduction of power demands and CO2 emissions effectively. In the conventional energy management programs, the demand response program that can transition or transfer the power use spontaneously for power prices and other signals has been largely used throughout the inside and outside of the country. For measuring the effect of such demand response program, it is necessary to exactly estimate short-term loads. In this study, the power consumption patterns in both individual and group consumers were analyzed to estimate the exact short-term loads, and the relationship between the actual power consumption and seasonal factors was also analyzed.

Demand response provides customer load reductions based on high market prices or system reliability conditions. One type of demand response, price-based program, induces customers to respond to changes in product rates. However, there are large-scale general and industrial customers that have difficulty changing their energy consumption patterns, even with rate changes, due to their electricity demands being commercial and industrial. This study proposes an in-house pricing model for large-scale general and industrial customers, particularly those with multiple business facilities, for self-regulating demand-side management and cost reduction. The in-house pricing model charges higher rates to customers with lower load factors by employing peak to off-peak ratios in order to reduce maximum demand at each facility. The proposed scheme has been applied to real world and its benefits are demonstrated through an example.

국내 컨테이너 물동량 증가로 이를 처리하는 하역산업 증가하였다. 하지만 1999년 이후 하역요율의 신고제 전환과 시설 공급 과잉으로 인해 하역사간의 과도한 요율경쟁이 발생하여 2015년 기준 컨테이너 하역 요율이 2000년에 비해 절반 이하로 하락하였다. 이에 본 연구에서는 하역 요율의 하락이 항만 물동량 수요에 영향을 미쳐 항만 하역산업의 시장을 확대 시켰는지? 아니면 과도한 요율 경쟁으로 인해 소비자잉여가 오히려 축소되었는지를 경제학적으로 분석해 보았다. 이를 위해, 본 연구에서는 기존에 항만부문의 경제적 가치를 추정한 연구에서 사용한 직접추정방식이 아닌 수요함수를 이용한 추정방식을 제시하였으며 소비자잉여 추정을 위해 타분야에서 주로 사용된 알렉산더방식 외에 힉스의 수요함수를 이용한 하우스만방식을 이용하여 추정의 신뢰성을 높였다. 그 결과 컨테이너 수출입 수요에 비해 하역 요율이 과다하게 하락하여 소비자잉여를 포함한 하역산업의 경제적 가치는 오히려 하락하는 것으로 나타났다. 한편, 향후 환적 컨테이너 물동량을 포함한 경제적 가치추정에 관한 연구가 진행되어야하며 나아가 항만산업 전체로 확대하여 현재 항만부문 예비타당성 조사 표준지침에서 이용되고 있는 경제적 편익 방식을 보완할 수 있어야 하겠다.

Much research has focused on the conflict and balance between work and family. Yet few studies examine how women feel in balancing these two roles. In that regard, this study examines how married working women feel balanced between work and family as well as the levels of support availability/demand that exists. The level of sense of balance regarding work-family is average. Sense of balance is related to age, income, work hours, size of workplace, numbers of family friendly policies, the family's attitude to woman's work, and the level of balancing strategies used. The demand for support is higher than the availability of support. Both factors are related to working hours and balancing strategies, etc.
