  • This study aims to evaluate the optimal size of the hydrogen facility to be installed in a zero-energy district in terms of load matching and facility efficiency. A mismatch between energy generation and consumption is a common occurrence in zero-energy districts. This mismatch adversely effects the energy grid. However, using an energy carrier such as hydrogen can solve this problem. To determine the optimal size of hydrogen fuel cells to be used on-site, simulation of hydrogen installation is required at both district-and building- levels. Each case had four operating schedules. Therefore, we evaluated eight scenarios in terms of load matching, heat loss, and facility operational efficiency. The results indicate that district-level installation of hydrogen facilities enables more efficient energy use. Additionally, based on the proposed model, we can calculate the optimal size of the hydrogen facility.

  • Objectives: This study was performed to investigate attitude and participation status on district health planning of officials in Health Centers. Methods: The data collected by self-administered questionnaire survey of 674 officials of Health Centers and the data on district health planning of 28 Health Centers in Gyeongsangbuk-do and Daegu metropolitan city were analyzed. Results: Only 13.6% of officials of Health Centers responded that they had read 'the second district health planning paper' thoroughly and 12.5% of officials of Health Centers replied that they had known contents of 'the second district health planning paper' fully. 56.9% of officials of Health Centers didn't have 'the second district health planning paper'. Thirty five point four percent(35.4%) of health center officials replied that the mayor's or county executive's concern about the district health planning was high, 22.4% in councilors, 77.8% in Health Center chiefs, 44.9% in Health Center officials, 43.9% in him or her. Among respondents, 58.6% of Health Center officials replied that district health planning was necessary and 38.0% of subjects replied that the degree of utilization of district health planning was high. About thirty seven percent(36.9%) of respondents participated in making out 'the second district health planning paper' and 49.6% in 'the third district health planning paper'. Health Center officials replied that the most serious problem of district health planning was 'lack of budget and personnels'(39.8%), 'lack of concern for district health planning'(21.4%) and the most important thing to improve district health planning was 'establishing department for health planning', 'adjustment of establishment time for district health planning'. Conclusions: In order to establish effective district health planning, it would be necessary to secure budget and personnels, to promote the county executive's concern and Health Center officials' concern about the district health planning, to establish department for health planning, and to adjust establishment time for district health planning.

  • Combined heat and power (CHP) system is one of the power generation system which can generate both electricity and heat. Generally, mid-size and big-size CHP plant in Korea generate electricity from gas turbine and steam turbine, then supply heat from exhaust gas. Actually, CHP can supply heat using district heater which is located at low pressure turbine exit or inlet. When the district heater locates after low pressure turbine, which called back pressure type turbine, there need neither condenser nor mode change operating control logic. When the district heater locates in front of low pressure turbine or uses low pressure turbine extraction steam flow, which calls condensing type turbine, which kind of turbine requires condenser. In this case, mode change operation methods are used for generating maximum electricity or maximum heat according to demanding the seasonal electricity and heat.

  • Nihombashi district, which is located in a heart of Tokyo Metropolitan area, has been flourished as a Japanese economic and cultural center since Tokyo was developed as a capital. Nihombashi district has still remained the Edo idea of stylishness since the government of Edo was established in 1603. During Edo period, population of Edo (former name of Tokyo) reached one million. Edo became one of big city around the world. Nihombashi district has been transformed as economical, financial and cultural center, along with modern transformation of Tokyo. During high economic growth (1955-1975), Nihombashi Bridge and River, which used to a symbol of Tokyo, have been covered with elevated highways. The river was polluted whereas the river does not have any relationship with people's daily activities. Since Japan has focused on environment concern in 80's, people and companies in Nihombashi district and Nihombashi River also requested to restore Nihombashi district and Nihombashi River. There are a lot of projects going on related to regenerate the river and the community, such as to remove highways covered with the river, restore river environment and run water navigation. This article mentioned to introduce the project of Nihombashi River and Nihombashi district that regenerate the community to capitalize history and geographic characteristics in Nihombashi district, to run water navigation through the river, and to review outcomes through various projects.

  • This is to report the result of Development of Single effect/Double lift absorption chiller & heater which is used in the district heating net work. The heating cycle was newly developed to make the secondary hot water from evaporator and the cycle change-over function was added for the heating to the cooling mode and the cooling to the heating mode. Finally, it was assured through the site trial operation that the outlet temperature of primary hot water can be produced lower than $68^{\circ}C$ when the outlet temperature of secondary hot water is $60^{\circ}C$.
