The primary purpose of this research was to set up the standard guidelines for the planning of interior architectural environments of the detention facilities at the Korean Police Stations. By visit-studying the actual interior environmental conditions of 5 different kinds' domestic Correcting Facilities and 5 domestic police detention facilities and 2 foreign police detention facilities, comparing them to the existing Korean correctional institutions' cell facilities, that the strengths and weaknesses had been analyzed to extract the main concepts and the planning scheme for the Standard Korean Police Detention Facilities. By reserching the National human Right Commitee's Anual Reports, three different indexes were picked out for those analysis : the Environmental control index, the Detention Service support index, the Environmental support index. These three indexes will be used as Key factors for the planning of interior architectural environments of the detention facilities at the Korean Police Stations.: (1)the Environmental control index to establish the Space Program, the Spatial Hierarchy and the horizontal & vertical Security Blocks, (2)the Detention Service support index for the central Environmental Control & Security System, the Secured Privacy for both detainees & police offices, (3)the Environmental support index for the gender-respected segregation of cell zones, the psychological & physical safety design factors, the construction standards of all rooms in a detention facility. The result of this study should be used as the guidelines for "The Standard Plans and Regulations for the Korean Police Detention Facilities" to respect fundamental human rights.

In this paper, the inundation simulations were carried out by using GIS tools for the analysis of detention efficiency based on the results of runoff analysis according to location and scale of regional detention facilities. The inundation maps could be drawn by the inundation simulations, and the locations and magnitude of inundation areas could be estimated through the inundation maps. The inundation simulations with GIS tools are approved to be the one of the useful method in designing optimized location and scale of regional detention facilities.

For the last two decades, Seoul has always been affected by large floods. As climate change causes more frequent localized heavy rains exceeding the capacity of sewer or river to discharge water, flood damage is expected to increase. Under the situation, detention facilities for lacking capacity of sewers can control stormwater runoff to reduce flood damage in urbanized areas. In this study, in order to reduce flood damage in Cheonggyecheon areas, the capacity of detention facilities was decided to make up for the lacking capacity of main sewers in case of the rainfall in July, 2001 as large flood. The average amount of stormwater detained in eight Cheonggyecheon drainage areas is $235.09m^3/ha$. Location and size of stormwater detention facilities is designed to have effects in short term by targeting the reduction of flood damage. Schools and parks are suggested as optimal locations where detention facilities are constructed in drainage areas.

This research is to investigate the detention facilities of police stations and their real operations through the perceptions of detainees at police station cells and to present the policy suggestions for them. To fulfill the research, a questionnaire was made out on the basis of 'the Regulation on Detention and Escort for Suspects'. 'the Regulation on a Standard Plan for Detention Facilities' and 'the Regulation on the Lowest Standard to Treat Detainees' ; and detainees at 23 police station cells under the jurisdiction of Kyungbuk Local Police Agency were asked to answer it. Policy suggestions following from the result of the investigation of detainees' perceptions of the detention facilities of the police stations are as follows; Firstly, the structure of police station cells should be arranged in straight lines in order to take their human rights into consideration and more detention facilities are needed to be built in order to separate male, female, handicapped and juvenile inmates. Secondly, shower rooms and washrooms outside the cells should always be open to detainees whenever they need to be used. Thirdly, any detention facilities deficient in fire fighting equipment should have exit doors installed as soon as possible in case of an emergency and provide sufficient fire extinguishers considering the number of detainees and the size of the facilities. Fourthly, the detention facilities should have sufficient windows for ventilation and take necessary measures to obtain natural lighting instead of electric lighting. Fifthly, air conditioners should be equipped properly taking account of the number of detainees and the dimensions of the facilities. Policy suggestions according to the result of the investigation of detainees' perceptions of the operation of detention facilities of police stations are as follows; Firstly, the problem of operating the detention facilities must deal with worn-out facilities and measures to secure the budget should be taken as soon as possible. Secondly, considering that most detained suspects have difficulties in livelihood, daily necessaries must be issued to them. Thirdly, personal belongings deposited by inmates must be properly managed with the same documentation throughout the police station detention facilities. The number of female guards to take exclusive charge of the physical checkups and processing of female detainees should be increased. Also the facilities for handicapped detainees must be expanded, improved and managed properly. Fourthly, except for handcuffs and ropes to bind detainees in the detention facilities, helmets to prevent self-harm must be withdrawn. The budget to improve the quality of meal issued by the government must be urgently secured and the price of private food sent to detainees must be readjusted to be in line with the consumer price. Health and medical care and sanitation for detainees must be substantial, and also sunbathing and outdoor exercises should be allowed to detainees.

Recently increased rainfall by abnormal climate, risen peak runoff by urbanization, and shorten time of concentration are causing frequent overflow at downstream basin. This problem will be solved through the runoff reduction facilities like detention pond. However so far, most studies about detention pond in Korea are focused on its capacity. A study with respect to outlet facilities of detention pond was insignificant. Design of culvert usually used for outlet facilities of detention pond is generally carried out by using "Road Drainage Design" of Korea Expressway Corporation (1991). So detention pond is unreasonable to apply it. In this study, the culvert flow in submerged condition of upstream at culvert was analyzed., and simplified design procedure for culvert outlet facilities were presented for detention pond.

National Emergency Management Agency is planning a flood disaster mitigation system in urban area. This research is about analysis of runoff reduction efficiency of the alloted detention system which is one of flood disaster mitigation systems in urban area. The alloted detention system is composed of small to middle size detention facilities located in up and middle stream of urban basin. To analyze runoff reduction efficiency of alloted detention system, basic runoff analysis in test area has been carried out and runoff characteristics with size and locations of detention facilities has been simulated. The results of simulation are showing that alloted detention system can reduce the discharge of main stream and detention facilities' size and locations are major parameters of runoff reduction efficiency. It is concluded that alloted detention system can be a useful method in urban area's flood disaster mitigation and can secure safety against flood damages in urban areas.

This study is to develop the suitable hydrologic models for determination of the size and location of detention storage facilities to restrain stormwater runoff in urban areas. Fictitious areas of two levels are considered to seize the hydrologic response characteristics. A one-square-kilometer area is selected for the catchment level, and a 10-square-kilometer area consisting of 10 catchments is adapted at the watershed level as representative of urban drainage area. In this analysis, different rainfall frequencies, land uses, drainage patterns, basin shapes and detention storage policies are considered. Flow reduction effect of detention storage facilities is deduced from storage ratio and detention basin factor. A substantial saving in detention storage volumes is achieved when the detention storage is planned at the watershed level than the catchment level. For the application of real watersheds, two watersheds in Seoul metropolitan area-Jamshil 2, Seongnae 1-are selected on the basis of hydrologic response characteristics. Through the regression analysis between dimensionless detention storage volume, dimensionless upstream area ratio and reduction rate of storage ratio, the regression equations to determine the size and location of detention storage facilities are presented.

To improve water quality for agricultural use, it is needed to introduce the natural and low-cost self-purification system. It is also necessary to develop the water purification facilities for more efficient and convenient design, construction, operation and management. This study aims to develop the practical facilities to improve water quality for agricultural use. The practical detention pond system, which uses artificial floating island and shield skirts with bio-media, enhanced removal efficiencies of SS, TN and TP more particularly than the detention pond using an auxiliary dam. The removal efficiencies SS, TN and TP for the practical detention pond were 55.7%, 61.0% and 55.9%, respectively. The facilities of the practical detention pond has a lot of disadvantages such as the low-cost and high efficiency as well as uncountable impacts regarding ecology and landscape. However, an auxiliary dam is recommended to be installed in shallow depth due to low efficiency.

Recently runoff reduction facilities such as detention ponds were rarely used and limited primarily to cases. A specific installation criteria and method of design for runoff reduction facilities is insignificant in our country. Also it has difficult problems with quantification. A detention pond being installed at outfalls and generalized in our country is adopted as basic form with infiltration facilities because quantification index for runoff reduction facilities have not been developed. A processing of detention pond design has to determinate storage volume and outlet form is very complex and wasting human resources and time in the planning step. In this study, we have been unified FFC11-SimPOND being able to simply calculate size with simplified design method of culvert outlet and made a computing model (SimPOND-CO) for practical users.
