At the current of the time, the ecologic stream is the most important concern of all the country. Daejeon metropolitan city performing the plan to secure the Daejeon cheon (stream) instream water as the 1st stage of the ecologic stream development plan for the Daejeon 3 main stream. During the performing the plan to secure the Daejeon cheon (stream) instream water, the water sources are decided to supply from Yudeng cheon and Daecheong Dam by the various water sources evaluation. For the investigation of flow and quality of instream water, I applicate the HEC-RAS and QUAL2EU. Instream water is proposed as the $10{\sim}30cm$ water depth and 2 degree water quality (lower the BOD 2.0 ppm) by the report of city. It is reasonable to the water depth objective, but the water quality objective is not reasonable because of the seasonal quality changes of supplied water. I suggest that the basin management plan include the non-point source elimination must comprised to the Daejeon ecologic stream project.

China is suffering from severe air pollution especially fine $PM_{2.5}$ pollution. In 2015, the annual average $PM_{2.5}$ concentration of the 338 municipal cities was $50{\mu}g/m^3$, 78% cities at or above the prefectural level failed to comply with the $PM_{2.5}$ concentration standards. The $13^{th}$ Five-Year Plan for National Economic and Social Development set the goal that the annual average concentration of $PM_{2.5}$ in the municipal cities which failed to attain the ambient air quality standards shall be decreased by 18% by 2020 (CCCPC, 2016). In this study, an air pollution control scenario during the $13^{th}$ Five-Year Plan period was proposed and the $SO_2$, $NO_x$ and PM emission reductions in response to different measures in 31 provincial-level regions mainland China by 2020 were estimated. The air quality in the target year (2020) was simulated using the WRF-CMAQ model. The results showed that by 2020, the emissions of $SO_2$, $NO_x$ and primary PM in mainland China will be reduced by 4.19 million tons, 3.94 million tons and 4.41 million tons, a drop of 23%, 21% and 25% respectively compared with that in 2015, and the annual average concentration of $PM_{2.5}$ will decrease by 19%. Coal-fired power plant contributes the most pollutant emission reduction.

During last 4 decades of industrial development, apartment has been rapidly disseminated throughout the nation. Its main progress, however, only appeared in quantity, not in quality. To promote housing industry in more way and to enhance peoples' life quality through the better housing environment, housing plan should be based on living items including furniture, appliances and etc. Not enough research has been done to find out living items for better house plan development and furniture design. Among living items, furniture reflects both directly and indirectly people's lifestyle and way of living. This study attempted to find out the pattern of furniture possession which people own in their bedrooms. An in depth questionnaire survey of 600 households was carried during the year 2000. A variety of patterns were found which indicated diverse living conditions within a very similar uniform multifamily apartment complex. The result of this study will be helpful to understand the living conditions in a more systematic way and to generate new concept for both residential unit plan and furniture design.

Recently cancer, AIDS, chronic sickness have increased according to the elevation of socioeconomic level and fast change of lifestyle. The number of patients receiving terminal care increased fairly because the span of life is extended by development of medicinal technology. Also necessity of hospice and palliative care was risen according to the request of terminal patients that remove pain and keep calm life by interest about quality of life. However architectural plan and type specialization of facility which can correspond team's composition and supplied nursing program are not consisting. This study researches about care environment of hospice facility plan through investigation into terminal patient's special quality. The purpose of this study is to propose fundamental datas of hospice facility for architectural plan through comparative analysis of cases of domestic and outside facilities.

Like today there is to a world-wide anger time where the culture flow is active and the life style which it follows in soul re-and economic growth of information anger and brother-in-law both culture of the world and consuming pattern against the eating and drinking space of the people are demanding the change which is various. Per the Korean-style food space composition quality instance - investigation analysis it leads and per the Korean-style food store plan hour it presents the standard of the space composition it will be able to refer with per the Korean-style food space composition plan hour efficient and rational there is the objective of the place where it provides a fundamental data to direction set of new plan.

The purpose of this study is to propose a simulation approach which compares lighting quality of each luminaire type for small urban park users' safety. For improving illumination quality, lighting intensity distribution of a luminaire is one of the important factors and it is also important to set the luminaire to a proper position. To achieve the best plan for illumination, it is most important to communicate the plan with designers of park and professional engineers in depth and the communication continues from the beginning of the plan.

This study suggest a plan for a small and medium auto parts enterprises in Ulsan Industrial Complex to do cooperation activity for management rationalization. To derive the plan, it is considered that characteristics of auto parts industry, existing status of cooperation activity, and faced problems of the small and medium enterprises in Ulsan area. Suggested plan may be well used for basic information of auto parts company's cooperation, and may contribute to expand cooperation activity.

Even though housing industry has greatly developed through last 4 decades, its main progress only appeared in quantity not quality. To promote housing industry in more sound way and to enhance peoples' life quality through the better housing environment housing plan should be based on living items such as furniture, appliances and etc. Not enough research has been done to find out living items for better furniture & house plan development. This study attempted to find out furniture pattern which people own in their bedrooms and livingrooms. An indept questionnaire survey of 600 households were carried during the year 2000. A variety of furniture pattern were found which indicated not uniform living items within a very similar uniform multifamily apartment complex, indicating of their living. The result of this study will be helpful to develop new concept furniture and also to suggest new space dimension for Apartment plan.

The policy of total maximum daily load (TMDL) was adopted to manage water pollutants so as to keep the total amount of pollutants in the watersheds within established target water quality. While the TMDL was implemented in all four major river basins, various problems occurred. Even though the corrections for problems were conducted, the role between central and local government was not established exactly. This study was presented to suggest a role between central and local governments for effective implementation of TMDL. When the central government establishes the environmental criteria with water quality standards and pollutants in the main rivers, the local government should establish the level of target pollutants in the watershed. Also, the local government should be continuously implementing the water quality and flowrate monitoring of the tributaries to find out the degree of water quality improvement in the tributaries. Especially, the basic plan of TMDL for the whole watershed should be established by the river basin environmental office at the central government. The local government should be established the implementation plan of TMDL for the watershed where exceeds the established target water quality. The performance assessment of TMDL should be implemented every year to the water quality and flowrate monitoring of the tributaries for satisfaction assessment of target water quality in the watershed by the lower-lever government. The performance assessment report of TMDL included with an analysis of causes for the excess water quality in the watershed should be submitted to the river basin environmental office at the end of the TMDL planning period.
