  • A system called demand response programs (DRP) is being introduced among various countries owing to the lack of new generation capacity and the higher fuel generation cost. It is a program which provides for the end-users to select their consumption of electricity by recognizing the value of their consumption in real time. That is, Demand Response can be defined as the changes in electric usage by end-use customers from their normal consumption patterns in response to changes in the price of electricity or other signals. It is expected that the effects of DRP are preventing price spike, improving supply reliability and social welfare and increasing option of customers. Considering the customer's thermal comfort zone, this paper determines the most profitable combination of optimal incentives and amounts of load reduction for a retailer to maximize profits according to predicted outdoor temperatures while implementing DRP.

  • This paper aims to empirically examine the short-run and long-run aggregate demand for the US imports using quarterly economic data for the period 2000-2018 including aggregate imports, final expenditure components, gross fixed capital formation and relative price of imports. According to the results of both multivariate co-integration analysis and error correction model, the above variables are all cointegrated and significant differences are found to exist among the long-run partial elasticities of imports as regards different macro components of final expenditure. Partial elasticities with respect to government expenditure, gross fixed capital formation, exports and relative price of import are found to be positive while imports seems to respond negatively to changes in private consumption, implying that an increase in private consumption could result in a significant reduction in demand for imports in the long run. With regard to the relative import prices, the results appear to indicate a relatively insignificant influence on the aggregate imports in the US in the long run. However, an error correction model designed for predicting the short-term variability shows that only exports have an impact on the imports in the short run.

  • Since public rental housings (social housings) in Korea are extremely standardized and uniformed, a variety of needs of residents for their housing are hardly satisfied. Public rental housing conditions, its low quality and size limitations regardless of residents type and needs resulted into negative images of social housing and social discriminations. Therefore there is a growing demand for alternative housing options in terms of diversification of social housing design with consideration for changing households and housing requirements. The purpose of this study to investigate some housing design guidelines, to analyze layout of building complex, community designs, household units and characteristics, overall design characteristics (sustainable design features, facade design, window and balcony composition, color and materials) and to provide some design suggestions for social housing. Design guidelines are classified into site planning and building layouts, residential building and household units, and performance of housing. Community facilities and their design features provide uniqueness of the public residence. Overall housing size of foreign cases is bigger than the domestic cases. Narrow shape of household units are more dominant in Korean public rental housing. More various shape and forms are found in facade and window design in foreign cases. Some design suggestion are provided for more diverse housing units and design for public rental housing in Korea.

  • Purpose: The purpose of this study was to develop and test a structural model on work-related musculoskeletal disorders of women workers. Method: Data were collected from 237 women workers from industries such as electronics, food production and garment production, and analyzed by LISREL 8.54. Result: The fitness indices of the model are GFI=.87, NNFI=.91, PNFI= .74. Eight out of the ten paths were proved to be statistically significant: work environment$\rightarrow$social support, work environment$\rightarrow$health behavior, work environment$\rightarrow$-WMSDs, domestic work$\rightarrow$health behavior, social support$\rightarrow$health behavior, social support$\rightarrow$job satisfaction, health behavior$\rightarrow$job satisfaction, and job satisfaction$\rightarrow$WMSDs. Work environment. social support, health behavior and job satisfaction significantly influenced WRMDs. WRMDs were accounted for 35% by the predictor variables. Conclusion: In conclusion, this study identifies that work environment, social support, health behavior and job satisfaction are important factors affecting WMSDs. Therefore, in order to prevent WRMDs, it is most important to improve both physical work environment for female workers such as appropriate work station and tools fit for them and psychological environment such as less job demand and more decision latitude(worker control).

  • In the past four decades, corporate social responsibility (CSR) issues have grown substantially due to the increasing demand for transparency and growing expectations that corporations should manage and improve their social, environmental, and economic performance. As a result, most organizations, companies, and governments provide CSR reports, while a large number of companies are still engaged in defining and integrating CSR into several aspects of their business. CSR is an obligation to society (Lee, 2020). The linkage between CSR and consumer-company identification (CCI) is important under company stakeholders. Consumers who care about those issues often change their shopping habits to bring greater value to the community. They will avoid buying environmentally or socially harmful products, and actively seek the products and services of the companies that carry out social responsibility. Companies conducting CSR activities such as charity works or environmental activities will be easy to associate as a responsible organization for always meeting the necessity of society. Therefore, companies must consider CSR a long-term strategy. The strategic approach to CSR plays an increasingly significant part in the business competitiveness - which helps create companies' values while gains trust and respect from the consumers, partners in particular, and the social community in general. This study is conducted to show evidence from project-based organizations about the CSR factors that influence consumer loyalty and the impact level of those factors on customer loyalty.

  • 대학의 직업기초능력 교육에 대한 기대와 비중이 갈수록 커져가고 있다. 대학은 사회에서 필요로 하는 인재 양성의 사회적 책무를 다하기 위해 다양한 방법으로 노력해 왔으나, 여전히 대학교육과 사회적 요구 간에는 다소 차이가 있다. 따라서 본 연구에서는 대학 교육의 주요한 결정 주체인 교수와 학생이 갖는 직업기초능력 교육에 대한 인식과 요구를 규명하여, 대학 교육이 학생 및 교수, 그리고 사회적 요구에 성공적으로 대응하기 위한 전략을 개발하고 운영하는데 도움을 주고자 하였다. 이러한 연구 목적을 달성하기 위해, A 대학 학생 475명과 교수 59명을 대상으로 직업기초능력 개발 교육에 대한 인식과 요구에 대한 설문을 개발하여 실시하였다. 설문조사 결과는 다중응답 빈도분석과 교차분석, 그리고 t 검정을 통해 분석하였다. 그 결과 직업기초능력 교육의 인식과 요구에는 교수와 학생 간의 의미 있는 차이가 나타났으며, 주로 취업과 미래 준비를 하는 데 느끼는 어려움의 정도와 취업과 미래 준비를 위해 가장 많은 도움을 받고 있는 곳과 방법, 직업기초능력 개발 혹은 취업을 위한 노력의 정도, 직업기초능력 개발 혹은 취업을 위한 구체적 노력 요인 등에서 차이가 나타났다. 직업기초능력에 대한 교수와 학생의 인식과 요구를 바탕으로 대학 교육에 함의를 제공할 수 있을 것으로 기대한다.
