The purpose of this study was to analyze the environment of poverty children as reported by the children on a questionnaire. The conception of the environment was divided into the physical environment and the sociopsychological environment. The dimensions of the physical environment included household, cultural, and play conditions. The sociopsychological environment included structural (family values, family relationships, and the reinforcement system) and process variables(affect, care, and communication). For the purpose of this survey was administered to 122 children living in a poverty area and 102 children living in a middle-high income area. Statistics used for data analysis were frequency, distribution, percentile, mean and one-way ANOVA. Major findings showed that (1) The physical environment as reported by the poverty children was meager compared with that of children in the middle-high income area: the households were more overcrowded, and cultural conditions, play materials, and space was more limited. (2) The Structural conditions of the sociopsychological environment as perceived by poverty children were more material and physical than that of children in the middle-high income area: family values were oriented more toward materialism: family relationships were more negative and distant: and the reinforcement system was based more on material reward and physical punishment. (3) Process variables were perceived by poverty children as more laissez-faire and rigid; the parents neglected their children and communicated unilaterally more than the middle-high income parents. (4) Poverty children's perception of the causes of poverty and wealth were perceived as personal and social factors.

The purpose of this study was to contribute to adolescents'welfare by investigating an actual condition of harmful environment and finding helpful ones. A total of 1125 questionnaires were used for the final data analysis. The study revealed the following results. 1. When it comes to spatial environment, adolescents go to PC rooms most frequently among facilities. They showed that the degree of use of harmful facilities is extremely low. The study revealed that frequency of exposure to harmful environment can be reduced more efficiently if adolescents are made to realize the harmfulness than when they are simply made to follow strict regulations. Significant differences were found in spatial environment according to gender and residence. 2. When it comes to informational environment, TV had an enormous influence on adolescent and they were exposed to computer at an early stage than expected. The frequency to see pornography was on the higher increase than ever, which showed outstanding difference according to gender. Also, pornography was mainly spread through friends.

The purpose of this study was to examine how the home and classroom literacy environment affect preschool children's story comprehension. The subjects were 213 pairs of children (aged 4-5) and their mothers, and 107 classrooms. The Home Literacy Environment Rating Scale (Park & Kim, 2008), Classroom Literacy Environment Observation Scale (Kim, Kim, Im, & Lee, 2008) and the Children's Comprehension Ability Test (Jung & Kim, 2003) were used in this study. The collected data were analyzed by means of two-way ANOVA, partial correlations, Pearson correlations, hierarchical regressions. Our results indicated that preschool children's story comprehension increases when both home and classroom literacy environment are well resourced and supported. In particular, it is essential that parents spend as much time as possible reading books with their children and that teachers provide children with an amply resourced literacy environment together with appropriate activities in class geared towards story comprehension improvement.

A pilot study was performed to examine the feasibility of multiple stage of constructed wetland (CW) for nutrient removal. The system is composed of six wetland cells connected with water-ways. The hydraulic of wetland cells is designed as free water surface flow. The treatment capacity was $25m^3d^{-1}$ at HRT of about one day for each cell. The magnitude of nutrient removal was related with the length of wetlands and plant density. Total N and P removal rates were 1353 and $246mg\;m^{-2}d^{-1}$ respectively. The pilot-scale reactor was model as continuous flow system containing contribution of CSTR and PFR typed-reactors. The $k-C^*$ model equation was applied to predict N and P reduction. The result indicated the equation was well guided to estimate reduction of $NO_3-N$ and $PO_4-P$.

It is not sufficient to control the indoor thermal environment using only one or two parameters by itself as human response for the control of indoor thermal environment. So a proper environmental thermal index is required for the control of indoor thermal environment effectively. In this study, the physical environment was measured and analysed and the skin temperature of the subjects and their response were investigated to evaluate the optimum thermal comfort range for cooling season in an apartment house. As a result, the optimal temperature was 26.1$^{\circ}C$ and the temperature ranges which more than 80% responded as satisfactory were 24.1~28.$0^{\circ}C$, respectively. As the OT had most significant interrelation with the PMV, it is desirable to use the OT in evaluating the thermal environment during cooling. Also, the comfort range was concluded between OT 25.5~27.3$^{\circ}C$ by appointing the PMV of -0.5~0.5 as the optimum comfort condition. In addition, the Human responses were compared with calculated PMV, OT and MRT and the relationships are suggested in order to utilize to control indoor thermal environment.

As the number of nursery facilities and infants who stay there is continuously increasing, IAQ (Indoor Air Quality) of nursery facilities should be managed strictly and thoroughly because infants are more susceptible to infections due to their low resistivity. In this study the characteristics of IAQ and ventilation associated factors were investigaed for suggesting a desirable condition for IAQ management. Environmental factors were not much related to IAQ characteristics rather than internal factors such as structures of the room. And the positive effect of ventilation on IAQ was obvious and seemed to hinge on factors related to window area especially window/wall ratio. Results of this study indicate that the structure with broader window area of a room and frequnet ventilation can be an effective way for keeping IAQ of nursery facilities clean and safe.

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.

Organic matters budget in Lake Hoengseong were monthly investigated from April 2009 to November 2009. The intense rainfall occurred at between July and August and the hydrological factors were highly varied during the rainfall season. By the concentrated rainfall, the elevation, influx and efflux were sharply increased and the turbid water was also flowed into the middle water column in Lake. The inflow of turbid water increased the nutrient concentrations in water body and this appears to stimulate of phytoplankton regard as the primary productivity of influx of organic matter. Monthly average concentration of dissolved organic carbon (DOC) was generally higher than the particulate organic carbon (POC) concentration in Lake, but Temporal and spatial variation of POC concentration was higher than DOC and the maximum POC concentration was recorded in surface water in August, had the highest phytoplankton biomass. Organic carbon concentration in inflow site was rarely changed during the dry season, but the concentration was rapidly increased by the initial intense rainfall. In organic matters budget, the most of the organic matters was inflowed from the inflow site at rainfall season. Especially, the influx of allochthonous organic matters during the intense rainfall was 72.4% in the total influx organic matters.
