The phosphorus contribution rate on water quality of North and South-Han River, and Gyungan-cheon by effluents from environmental fundamental facilities located in upstream basin of Paldang Lake were analyzed. QUALKO2 model was selected for the analysis of contrubution rate, and was constructed considering the location of the main point sources and all facilities in study area. The pollutant loading rates and arrival rates for each unit-watershed in study area were calculated for model operation. For the calibration and verification of model, 2006 water quality dataset from Ministry of Environment and the effluent loadings of the environmental fundamental facilities were used. Reliability Index (RI) method was used to estimate the validity of the results of calibration and verification. The phosphorous contribution rate(%) for each environmental fundamental facility were analyzed by excepting the effluent loading of the facility. The contribution rate was analyzed for each facility, facility groups separated by each main river and each unit-watershed. The main results of analysis for each facility are as follows; (i) the phosphorous contribution of B1 facility is 50%, which is the highest phosphorous contribution rate among those of nine facilities in the North-Han River Basin; (ii) the highest phosphorous contribution is 55.6% from J facility among eight facilities in the Gyungan Stream Basin; (iii) 40% from E treatment facility is the highest among those of twenty eight facilities in the South-Han River Basin.

In korea, 500MW standard coal fired power plants were designed and operated for the initial base load, so facility stability was prioritized from facility problem to treatment, but now we needed to research for minimizing greehouse gas emissions at the operation of coal fired power plants. research on various facilities and technologies was actively conducted to reduce environment pollutants was drastically reduced, but research and attempts on coping measures in the event of a reduction facility problem were in sufficient. this study considered investigated ways to minimized pollutants by quickly responding to logic development and application of the load runback concept in case of serious problems with environmental pollutant reduction facilities such as NOx reduction selective catalytic reduction facilities, SOx reduction wet flue gas desulpherisation facilities, and TSP(Total Suspended Particles) collection low temperature electric precipitator.

The purpose of this study was to evaluate the sanitary management of hotel employees in Seoul. The results were summarized as follows : The total mean of sanitary management perception by factor was 3.91${\pm}$0.62, in which personal sanitation, property management, environment and facility factors were, in order, 3.99${\pm}$0.82, 3.91${\pm}$0.75, 3.90${\pm}$0.86 and 3.85${\pm}$0.82, respectively. This study showed that there was a significant difference in the perception of sanitary management among environment, facility and property management by age based on general characteristics. While there were no differences by hiring type, there was a significant difference among environment, facility and property management with personal sanitation factor according to the employee’s career path. There was also a significant difference between property management and personal sanitation factor according to hotel management style. In addition, a significant difference was observed among environment facility and property management with personal sanitation factor according to work place. In conclusion, it is imperative to continue educational programs for sanitary management by career, work place and management style in order to improve sanitary management of hotel employees’.

The objective of correction is to let criminals receive education, be reformed and get vocational training during prison term by being separated from society and live as sound citizens after being released from prison. The facilities that execute such mission are referred to as corrective institution, and in Korea, some 47,000 persons are accommodated at 50 locations. Corrective facilities are facilities existing to separate and accommodate criminals safely, and return them to society after eliminating criminal nature from the convicts during the accommodation period. But corrective facilities in Korea representing the characteristics of corrective facilities vividly focusing on security. Therefore, while present pursuit of corrective facilities is to seek for reformation of criminals rather than separation of them from society, existing prison buildings are not appropriate facilitated at the moment. This study has the purpose to planning of indoor environment of corrective facility ward building as healing environment. Specifically, this study is contributing to propose a model of criminals healing environment equivalent to hospital facility to raise the effect of healing the criminal nature of criminals and cut the period of restoring them by applying healing environment elements and return the criminals to the society as successfully reformed social member.

Purpose: Mental health facilities are facing a new social environment. To provide appropriate patient care environment, mental health and mental healthcare is changing the paradigm. In this situation, this study research and analysis mental healthcare service system and mental healthcare facility in Germany. The reason is that Germany has cosistently been building mental healthcare service system and mental healthcare facility for patient. Therefore, it aims to suggest a fundamental resource for amental healthcare service system and mental healthcare facility for mental healtn. Methods: This study was conducted literature researches and field studies. Literature researches for mental healthcare service system and facilities. Field study is to identify the characteristic and configuration of mental healtncare facilities. Results: Findings of this study can be summerrized inth three points. First, In Germany, Mental healthcare facility is critical environment in the community. And, the facilities are being turned into reasonable and alternative environment. Second, Facilities of Mental healthcare and service system designed by various level and configurations that can be providing places for people with mental problems. Third, Mental healthcare facilities consist of healing environment for patient. Implications: The future study on finding of the specific environment planning citeria in mental healthcare facility on the basis of findings of present study.

According to the educational statistics and information data, there were 11,317 elementary school, middle school and high school facility as of 2011. During the post decade, 1,256 schools are increased. The school facility maintenance is the important factor for the whole facility life cycle because it determines the useful life of a facility. Current school facility maintenance practices tend to ad-hok kery, namely, repairment is made after a problem is discovered. The purpose of this study is to propose the new maintenance works and management system to improve the process of maintenance. In addition, the authors suggested school facility improvement plan based upon the questionnaire survey of related management officials.

Global environment is getting deteriorated at an alarming rate. Eco-school could be one of the effective solutions to project our environment and a good sample of architecture to economize in total energies, resources and greenhouse gases. In case of our country, the study of eco-school planning is not sufficient compared with other countries, so this paper would be a good study on the indoor environment of the classroom by surveying their opinions and ideas from the group of users in school facility. The result of this study shows that the proper installation of building equipment and nature ventilation system is necessary to provide delightful environment for the students and to save the energy. To ensure that we have adequate saving and protection it is necessary to change the existing appraisal standard.
