For the sake of a stable power supply, an electric power company must have power generation facilities that can generate more electricity than the maximum demand of the year. Due to the fact that the maximum electricity demand will also continue to increase, enormous investments are needed annually to build power plants. For that reason, electric power companies are propelling 'Demand Side Management' which improve the form of electrical usage for the customer in a positive way. This paper presents the concept of 'Cool Storage System' which is the most representative program, which lowers the peak demand during the on-peak time periods in a day and creates a base load simultaneously during the night time hours among the DSM programs.

The purpose of this study is to design appropriate digital tools for the production of makeup designs. In this study, we used a three-dimensional facial avatar simulation program developed by the Electronics and Telecommunications Research. This study is based on the creation of three-dimensional CG digital art of facial avatar makeup, produced by using simulation technology. First, the actual application and the tools for digital-optimization and media features were created, leading to the research and cleanup. Second, the theoretical background was applied to the formative elements of oriental colors in the designing process. Makeup design elements include point, line, surface, color, and texture. In this study, effective makeup design was interpreted to be based on the representation of particular elements, notably the design principles of balance, proportion, rhythm, repetition, emphasis, contrast, harmony, and unity. In Asia, design is based on the visibility of red, blue, black, yellow, and white-the colors of the five elements-and the use of points, lines, and shapes. This study was recently under scrutiny in relations to digital simulation and various three-dimensional designs, in terms of how to take advantage of a wide range of applications, and how to apply the findings through media and the dissemination of basic research. This study applies the characteristics of the limited existing stereoscopic three-dimensional and digital simulation programs in order to take advantage of the empirical research, providing a basis to implement this research in a meaningful way. A follow-up study is needed to extend these findings and theoretical foundation through continuous observation and in-depth technical development and research.

Objectives: The Indonesian Ministry of Health launched isoniazid preventive therapy (IPT) in 2016, with general practitioners (GPs) at the frontline of this program. However, the extent to which GPs have internalized this program remains uncertain. The aim of this study was to identify the knowledge and attitudes of GPs towards the IPT program in Indonesia. Methods: This study used an online, self-administered questionnaire distributed via e-mail and social messaging services. A logistic regression model was employed to identify the explanatory variables influencing the level of knowledge and attitudes toward IPT among GPs in Indonesia. An empirical analysis was conducted separately for each response variable (knowledge and attitudes). Results: Of the 418 respondents, 128 (30.6%) had a good knowledge of IPT. Working at a public hospital was the only variable associated with good knowledge, with an adjusted odds ratio (aOR) of 1.69 (95% confidence interval [CI], 1.02 to 2.81). Furthermore, 279 respondents (66.7%) had favorable attitudes toward IPT. In the adjusted logistic regression analysis, good knowledge (aOR, 0.55; 95% CI, 0.34 to 0.89), 1-5 years of work experience (aOR, 2.09; 95% CI, 1.21 to 3.60), and having experienced IPT training (aOR, 0.48; 95% CI, 0.25 to 0.93), were significantly associated with favorable attitudes. Conclusions: In general, GPs in Indonesia had favorable attitudes toward IPT. However, their knowledge of IPT was limited. GPs are an essential element of the IPT program in the country, and therefore, adequate information dissemination to improve their understanding is critical for the long-term viability and quality of the IPT program in Indonesia.

2010 is the year when the Korean baby boomer generation faces retirement. With the need for affective strategies to keep this population healthy, the government has placed much effort to increase the regular physical activity (PA) level of older adults. Yet the prevalence of active seniors is still relatively low. This paper reviews the recent government strategies and efforts to enhance the physical activity levels of older adults and the PA programs provided in the community settings by major organizations and institutions. In addition, the problems of the current approaches are shown, and based on a review, the author provides five suggestions for promoting the PA level of older adults as follows. First, specific physical activity goals and objectives for older adults should be included in the National Health Plan 2020. Second, the recommendations for PA for seniors, which include a proper intensity, duration and frequency of exercise, should be provided. Third, the role of organizations and institutions should be rearranged for the proper dissemination of government provided community-based exercise programs. Fourth, a standard quality-control system should be provided, and finally, an evidence-based exercise program, which should be specifically created for the older Korean population, should be developed. Physical activity offers opportunities for people to extend the years of their active independent life and reduce functional limitations. To maximize the effects of government efforts to promote PA for seniors, we feel the comments provided in this paper should be closely examined.

Background: McKeown first described two autopsy cases of esophageal small cell carcinoma (SMC) in 1952; about 230 cases have since been reported in the literature. Small cell carcinoma has been reported to account for 0.4% to 7.6% of all esophageal malignancies. SMC of the esophagus as regarded as having a poor prognosis with frequent systemic dissemination. Choice of treatment remains controversial. Material and Method: From August 1987 to December 1998, a review of the records and histologic sections of 8 patients with primary small cell carcinoma of the esophagus seen in 11 years was undertaken. Result: Small cell carcinoma of the esophagus constituted 1.5% of all esophageal cancers. The median age was 61.5 years(range from 42 to 71 years). Seven patients were male, tumor was mainly located in the middle and lower thirds(6 cases) of the esophagus. Pure SMC is 5 cases, and mixed SMC is 3 cases. Operative procedure were as follow: transthoracic esophagectomy with thoracic or cervical reconstructon in 7 patients, transhiated esophagectomy with cervical reconstruction in one. The operative death was none. Adjuvant chemotherapy was performed in 7 patients except one who had poor general condition. Recurrence was observed in 4 patients(mediastinal LN, abdominal LN, SCN, bone). The overall median survival was 15.9 months. Only one patient survived for more than 5 years. Conclusion: We considered that esophageal SMC should be regarded as a systemic disease, and multimodality treatment including chemotherapy should be used. Surgery may be offered in selected patients to manage local disease as part of a chemotherapy based treatment program.
