The purpose of this study is to analyze and interpret the ponds appeared in the Korean traditional temples. Summarized findings are as follows: First, it appeared that the location of ponds of the Korean traditional temples is, in general, in both the entry space and transitional space of temple. And it is considered that such configurations of the location of ponds were done intentionally in order that the ponds should have a significance as same as the concept that a natural mountain stream separates the sacred place and the secular world. Second, since the size of the ponds appeared in the temples are considered to be what is transformed from the original one, it is hard to understand the real size. However, it is judged that since ponds we see at present played an element of the total space of a temple it is deemed that no significant change of the size of ponds have happened if the size of the structure a temple itself has ever changed. Third, it appeared that the forms of the temple's ponds are diversified in a square, oval, egg-shaped one, round shape(circle), natural shape, etc. and it is identified that most of the ponds inspected for this study appeared to be in shapes of an oval, egg-shaped one, and round shape which take a typical curve. Fourth, regarding the temples whose origins are from the Baekje dynasty or Shilla dynasty among the objects of this case study, there appear some uniform styles for each temple respectively. For example, in both the Junglim Temple's twin pond(定林寺 雙池) and the Mireuk Temple's twin pond(彌勒寺 雙池) which were built in the Baekje dynasty appears a twin-pond in a square shape, and in the Bulkuk temple(佛國寺), Haein temple(海印寺), Tongdo temple(通度寺), etc. which were built in the Silla dynasty appears the ponds in an egg-shape one. Fifth, regarding the function of the ponds appeared in the temples, the ponds are characterized with a lotus pond(蓮池), reflecting pond(影池), and pond complex(蓮 . 影池). In consideration of the 20 ponds in the 15 places of this study's object, there are 8 lotus ponds(蓮池), 6 reflecting ponds(影池), and 6 ponds complex(蓮 . 影池).

Geochemical study was carried out to find out soil contamination at the heaped soil, moved from bottom of the storage pond in Pohang industrial complex, in Moondug, Chemical analysis showed that contents of heavy metals in the soil were higher than those of the ordinary soil. Contents of Cu and Cd in the soil exceeded Korean standard of soil contamination. Especially content of Cu exceeded Korean standard of soil contamination(50ppm) at the six points and at one point content of Cu was 113.3ppm. Contents of Be were so higher than U.S RCRA standard(0.2ppm) that they can affect soil environment. The followed research about relation between pollutant and soil and proper measures are required to prevent soil contamination from affecting environment of Moondug.

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.

Occurence, seasonal changes and vertical distribution of the silica-scaled chrysophytes in a small fish-free pond were studied using electron microscopy (EM) and light microscopy (LM) from October 1998 to July 1999. The phytoplankton community was characterized by Chrysophyta and Cryptophyta. Ten species of the silica-scaled chrysophytes of genera Mallomonas, Synura, Chrysosphaerella and Spiniferomonas were identified by EM, and the most abundant species were Mallomonas akrokomos and M. portae-ferreae. The maximum population density of M. akrokomos was observed in December and several peaks appeared periodically at about one to two month intervals, whereas M. portae-ferreae developed the maximum density in March. The diurnal vertical distribution of M. akrokomos exhibited clear downward migration at night and slightly upward migration in the morning. A complex interaction among physico-chemical and biological factors seemed to affect the vertical distribution of M. akrokomos. However, the seasonal changes of M. akrokomos did not show significant corre1ations with the physico-chemical and some biologica1 factors. Although M. akrokomos was evenly distributed throughout the water column during some experimental periods, the diurnal patterns found in the two diurnal cycles showed consistency in that it clearly avoided the surface water during the day. This suggested that M. akrokomos may be a shade plankton with maximum densities below surface layer.

The Back garden in Wanggung-ri Site, Iksan clearly presents an aspect of the landscape gardening techniques of the Baekje, which are significantly unique in the landscape gardening history of East Asia as the structure connected to the main garden through a complex waterway system on a hill. The rear garden has a complex waterway system comprising a large inverted U-shape waterway and its branch waterways, sinuous waterway and water catchment system to enhance the landscape effect with a minimum amount of water on a hill, reducing damage by floods in the case of heavy rain and securing the amount of water required by the main space in the palace. A landscape element using various kinds and sizes of oddly shaped rocks decorated the water catchment area inside or around the large inverted U-shape waterway. On the top of the hill, the center in the Back garden, a building site in the size of 4 Kans each on the front and side was made on a square base surrounded by a round base stone. The building was identified on a space partially surrounded by the rectangular stonework on the left and right slope of the hill. While the functions and roles of the rectangular stonework are not accurately identified due to the poor conditions of the present site, the stonework may be related to the building inside it. The back garden in Wanggung-ri Site, Iksan has a winding pond-shaped waterway to pull or push water into or out of the garden in a rectangular pond shape, which was a conventional landscape gardening technique during the Baekje period. Since the main garden and the back garden in Wanggung-ri Site, Iksan form a systematic connection system, this paper tried to newly establish the main garden inside Iksan Wanggungseong as the 'royal garden'.

An eco-friendly water purifier was developed using natural minerals, plants, and sludge from water purification plants. A wastewater complex treatment system using this water purification agent was developed. The wastewater complex treatment system goes through the process of inflow of contaminated water, input of water purification agent, operation of a pressurized flotation device, sludge flotation, sludge collection and treatment water discharge. This device was applied to the removal of green algae in livestock desorption liquid, broiler washing water, factory wastewater, sewage treatment plant and pond to obtain excellent removal rate. The use of natural water purification agents for organic waste purification has not been investigated.

Construction of the water-friendly facilities in the apartment complex and industrial complex became popular these days. In planning water-friendly facilities, kinds, layouts, water sources, water quality and water circulation system should be studies. In this study, several alternatives for a regional industrial complex project were studies and a most reasonal alternative was selected. A main canal across the central part of the complex is the principle facility with ponds and parks. The water source alternatives were a river nearby, a reservoir, ground water and urban water supply system. For each system, water quantity and quality, circulation system, permit and maintenance were compared. The facilities should be constructed with natural material such as rock and gravel. Average depth and velocity in the canal should be 10 cm and 0.15 m/s, respectively in order to people can feel the water flow in the canal. Based on the comparison, it is found that using the ground water, and water circulation system with storage tanks at the upper and lower ends of the canal system is the best alternative.

Up to date, the majority research on the major landscape elements in organic farming has been mainly focused on the practice of seeking efficiency. The problem is that this type of study contributes to polluting the agricultural environment and damaging the ecological circulation system. As an alternative, there is a growing body of research on organic farming, but it is not widely applied that research on how to manage the landscape considering the scenic characteristics of farming villages practicing organic farming. Hence, in this paper we utilized landscape adjectives as a way to enhance the objectivity of the organic agricultural complex landscape assessment. More specifically, not only this study used a landscape image of an organic agricultural complex to identify a landscape adjective suitable for the landscape elements but also this study confirmed the suitability of landscape adjectives comparing to the opinions of experts and the public. To carry out, this study performed the experts survey which is composed of 12 major landscape elements, including rice paddies and fields, monoculture and diverse crops, dirt roads, windbreak trees, accent planting, dum-bung(small pond), natural small river, natural waterways, plastic film houses, one-storied houses, and pavilion. As a result of deriving the landscape adjectives from the main landscape elements, there were nine landscape adjectives that were consistent with experts and the public, including "clear" and "Artless" for rice paddies and fields, while the mismatched landscape adjectives were 'traditional'. The accent planting was a combination of landscape adjectives such as 'natural' and 'clear', while the windbreak trees was a consensus of all landscape adjectives. Only two adjectives, 'friendly' and 'wild', agreed on the dirt load, nine dum-bung(small pond), ten natural small river, nine duckery, eight one-storied houses, 10 pavilion, eight monoculture and diverse crops, and three natural waterways. The most common landscape adjectives were windbreak trees, pavilions, and natural small river, all 10 landscape adjectives. However, it is considered that only three of the 10 landscape types on the dirt road and the natural number are matched. Thus, additional management measures will be needed. In addition, it was analyzed that the most common landscape adjectives were "Artless" and "friendly" 13 times. The landscape adjectives of the organic farming complex responded by experts were analyzed to be suitable for natural, clear, zingy, silent, traditional, artless, friendly, wild and Leisurely, and consistent with the general public's opinion.

The purpose of this study is to examine the residents' preference to community facilities in national rental apartment complexes. Twelve housing complexes were sampled and researched with questionnaire and field-surrey methods. The data from the questionnaire survey were processed with SPSS 14 and analyzed by regional group, size of complex, and arrangement plan of facilities. The complexes are located in two legions, Seoul and Gyounggi province. They were also sorted into three groups by size: less than 500 households, 500 to 1,000, and more than 1,000. Lastly, the complexes were categorized into three types: those where facilities are concentrated in or around a single building, dispersed into several places, and located in residential buildings. The results are as follows: Majority of the community facilities are established outdoor and, therefore, the indoor facilities are relatively more insufficient. Especially, there is a shortage of indoor gymnasium while the demand is increasing. It is partly because there is no regulatory guideline on indoor gym requirements in housing complexes. The resident satisfaction measurement shows significant comparison according to region and complex size. The level of satisfaction with garden/kitchen-garden, pond/fountain/streamlet is higher at the complexes in Gyunggi. The residents of larger complexes give positive feedback about spells facilities while those of smaller complexes are more satisfied with education-related facilities such as library and study. The measurement of resident needs shows significant comparison according to complex size and facility arrangement plan. The residents of smaller complexes are more in need of community facilities. In both regulatory standards and actual condition, community facilities are more insufficient at small complexes with less than 500 households.
