  • This paper is developed to demand management scenario of energy consumption efficiency improvement, electricity generation efficiency improvement, network efficiency improvement, change of distribution ratio, movement of energy source, change of heating system, put of CHP to quantitatively assess to impact on energy use of demand management at the national level. This scenario can be applied Energy System Management model was developed based on Energy Balance Flow. In addition, effect analysis through built demand management scenario was quantitatively evaluated integrated demand management effectiveness of energy cost saving, CO2 emission reduction and energy savings of national level by calculating to primary energy source usage change in terms of integration demand management effect more often than not a single energy source separated electricity, heat and gas.

  • A numerical method of calculating the performance of a scroll compressor for refrigerant R-22 and R-134a is presented in this paper. A series of involute curves are employed for the scroll wrap design and the compression volume is investigated geometrically. The radial leakage flow rate through tip clearance is calculated by the two-dimensional compressible flow. On the basis of the results, quasi one-dimensional leakage modeling can be applied to the performance analysis of a scroll compressor, more effectively. Furthermore, the heat transfer effect between scroll wrap and working fluid in compression chamber is considered for the performance analysis. As the results of this study, the effects of the radial and tangential leakage flow rate and heat transfer on the scroll compressor performance are derived precisely. These results may provide the guideline for the design and development of a real scroll compressor.

  • According to diffusion and wide utilization of Radio telecommunication, demands of radio frequency source are increasing. Thus, we have o continuously study on regulations which should be managed efficiently and usefully for father technical developing. In this paper dispute bout developing radio frequency police depends on changes of conditions and sing radio frequency source depend on a variation of environment and an advance of technique and then we consider a international agreement and an amendment of international regulations for an alternative proposal so that we suggest foundations of national radio regulations for revisions and decisions connect with radio frequency control policies and rules.

  • Indonesia has a population of more than 260 million, of which, by 2020, Generation Y is predicted to account for 70% of the total. With different birth years, Generation Y is the backbone of Indonesia's product purchasing. Generation Y is interested in establishing strong relationships with specific brands on social media. They are also interested in working with companies to design a product. Most Generation Y utilizes more than one electronic device and they are also brand loyal. Therefore, this study seeks to examine the effect of social media (i.e., e-WOM, online community, and online advertising) on brand image and loyalty in Generation Y in Indonesia. The sampling method employed was purposive sampling. A total of 150 respondents in the age range of 23-30 years were involved as the sample. Using multiple regression model in data analysis, this study proved that e-WOM, not only have a positive and significant effect on the brand image, but also on brand loyalty. Furthermore, online community also positively and significantly affects brand image and brand loyalty. Likewise, online advertising has a positive and significant effect on brand image and brand loyalty. This study's findings indicated that all the proposed hypotheses were well accepted.

  • The purpose of Emergency Medical System(EMS) is what a patient returns to society with recovering mental tone in the shortest time as giving prompt and proper medical treatment to patient in emergency situation, and the Correctional Administration(CA) is purposed for the convict to return and settle down to society after release from prison in success as executing schooling, enlightenment activity, vocational training to convict who was quarantined from the society for the term of imprisonment. The EMS and CA will coincide each other which is reverting people to society in safety. This study aims to suggest the developmental program of EMS in correctional facilities through the cause of emergency situation, system, human resources, establishment, medical equipments, state of budget and the point issue for safety of victim who has many chances that is exposed to physical damage and disease because of particularity of lower culture in correctional facilities and the staff who works there. First, in the view of the correctional facility security system, a proper number of the emergency rescuers should be employed. Second, the effective transportation system along with some emergency medical equipment needs to be established. Third, the correctional officers and the prisoners should be learned the first-aid training which is realistic, practical and systematic. Fourth, the cooperative system should be established such as 1339 emergency medical information center in society. Fifth, the Ministry of Health and Welfare must increase EMS budget for correctional facilities.

  • Objective : This experimental study was designed to determine the effects of BPT on obesity in vivo and in vitro. Methods : in vitro, BPTn extracts of various concentration(50, 100, 200 ${\mu}g/m{\ell}$) were added in 3T3-L1 cell. Adipocyte differentiation was measured by Oil Red O staining and Morphological examination. The expression of $C/EBP{\alpha}$ and $PPAR{\gamma}$ receptor was measured by western blot assay and RT-PCR in vivo, Rats were orally administered BPT daily for consecutive four weeks before poloxamer-407 induced hyperlipidemic state. The rats were sacrificed 24 hrs later for poloxamer-407 treated and then serum triglyceride, total cholesterol were measured ; Rats were orally administered BPT daily for consecutive four weeks before triton WR-1339 induced hyperlipidemic state. The rats were sacrificed 40 hrs later for triton WR-1339 treated and then serum triglyceride, total cholesterol were measured ; Rats with obesity were induced by the high fat-diet for six weeks and then serum triglyceride, total cholesterol, LDL-cholesterol, triglyceride, HDL-cholesterol, hydroxy radical, superoxide dismuatse activity were measured. Results : In vitro, The 3T3-L1 cells' differentiation was significantly decreased by BPT. The expression of $C/EBP{\alpha}$ and $C/EBP{\beta}$ was decreased by BPT. In vivo, BPT significantly reduced serum triglyceride, total cholesterol contents in poloxamer-407 treated rat. BPT significantly reduced serum triglyceride contents in Triton WR-1339 treated rat. Total cholesterol also reduced but did not show a significant change. BPT significantly reduced body weight gain of rat and adipose tissue mass of rats and serum triglyceride, LDL-cholesterol contents and significantly increased HDL-cholesterol, HTR(HDL-cholesterol/Total-cholesterol) in rats with obesity induced by the high fat-diet. BPT reduced blood lipid peroxide, hydroxy radical and increased superoxide dismuatse(SOD) activity.
