The channel improvement plan has contributed to the flood damage reduction studies and the plan has mainly performed by the levee construction which creates the cut river. The cut river has mainly used as the agricultural and housing purposes. Recently, however, it is considered as a natural wetland for the purposes of a flood control and preservation of nature. So, this study compares the economical benefits according to the purposes of the cut river utilizations such as an agricultural, levee construction for flood damage reduction, and wetland. The study area is the downstream part of Kok-Neung stream which is a main tributary of Han river. The agricultural and levee construction benefits are estimated based on the 'Agricultural and Forestry Statistical Year' (2000) and the 'Standard for River Design' (2001). The benefit or value for the wetland utilization of the cut river is estimated by the enquete using questionnaire. As a results, for the case of which the cut river is used as an agricultural land, the present net benefit is estimated as 195.81 million won, for the levee construction, as 20853.00 million won and for the wetland, as 24692.89 million won. Therefore, the wetland is the best choice for the cut river utilization.

While various fiscal measures have been used to influence regional capital inflow or industrial location, the effect of fiscal variables on labor mobility has been little understood. Understanding the relationship between the composition of local public and urban migration would enhance the city govenment's ability to pursue an appropriate population policy. In order to examine the potential for local public finance to be utilized as a policy tool in directing urban population growth, this paper analyzes the impact of local government financial structure on urban migration. In examining the data on local government finance and the changes in population of Korean cities during the last ten years, it was found that cities with high per capita expenditure in regional development have experienced high population growth rates. In this study migration equations were constructed using various fiscal variables such as the proportion of special account expenditures which are mostly spent for local development purposes, per capita regional development expenditure, degree of local financial independence and per capita net fiscal benefit, along with other explanatory variables. The results of regression analysis showed that city government's regional development expenditure variables have a positive effect on urban net migration and a negative effect on outmigration. Fiscal independence and per capita net fiscal benefit had mixed effects on in and out migration variables, implying that local tax burden does not consistently deter inmigration or induce outmigration. Based on the results of this study some important policy implications can be found regarding local government's fiscal policies. Those cities seeking to attract higher population inflow should make a greater effort in appropriating local expenditures for regional development purposes such as infrastructure, housing, and transportation. city governments should not be too concerned about high local tax burden or necessarily seek to enhance financial independence for these factors do not exert a clear influence on urban population growth or labor supply.

The purpose of this study was to found that the important design reform points for improvement of the public open space quality. For this purpose, surveyed the users of the public open space and the experts working for the public open space planning for the design elements of the public open spaces in terms of importance and satisfaction. The scope of the study was limited to Mapo-gu, Seoul and the buildings constructed since 1992 were sampled. the data collected were subject to Importance-Performance Analysis. As a result, 'waste boxes, vending machines and other amenities', 'characteristic floor and pedestrian environment', 'designs and their layout in harmony with the surrounding and landscape facilities', 'facilities checking and patrol for safety' and 'entire area of the public open space'. Based on the above findings, the following reform measures are put forwards for improvement of the public open space quality; First, the public open spaces should be equipped with sufficient amenities. Second, it is necessary to check the facilities regularly, while enhancing the safety through patrols. Third, it is essential to reflect user's needs in public open space planning, while applying the important design elements to the public facilities. Fourth, in order to create a comfortable pedestrian environment within the public open space, it is deemed necessary to divide the space into the passages for passers-by and the recesses for uses. Fifth, it is necessary to amend the Building Code to the effects that the radio of the landscaped area to the entire area can be readjusted together with the night lighting facilities. Sixth, it is desirable to give the weights to the important design elements for the public open spaces, so that the quality public open spaces can benefit from the incentives. In addition, regular maintenance and management should be ensured by policies.

Objectives : The aims of this paper were to develop the composite deprivation index (CDI) for the sub-district (Eup-Myen-Dong) levels based on the theory of social exclusion and to explore the relationship between the CDI and the standardized mortality ratio (SMR). Methods : The paper calculated the age adjusted SMR and we included five dimensions of social exclusion for CDI; unemployment, poverty, housing, labor and social network. The proxy variables of the five dimensions were the proportion of unemployed males, the percent of recipients receiving National Basic Livelihood Security Act benefits, the proportion of households under the minimum housing standard, the proportion of people with a low social class and the proportion of single-parent household. All the variables were standardized using geometric transformation and then we summed up them for a single index. The paper utilized the 2004-2006 National Death Registry data, the 2003-2006 national residents' registration data, the 2005 Population Census data and the 2005-2006 means-tested benefit recipients' data. Results : The figures were 115.6, 105.8 and 105.1 for the CDI of metropolitan areas (big cities), middle size cities and rural areas, respectively. The distributional variation of the CDI was the highest in metropolitan areas (8.9 - 353.7) and the lowest was in the rural areas (26.8 - 209.7). The extent and relative differences of deprivation increased with urbanization. Compared to the Townsend and Carstairs index, the CDI better represented the characteristics of rural deprivation. The correlation with the SMR was statistically significant and the direction of the CDI effects on the SMR was in accordance with that of the previous studies. Conclusions : The study findings indicated mortality inequalities due to the difference in the CDI. Despite the attempt to improve deprivation measures, further research is warranted for the consensus development of a deprivation index.

This review has been done to examine sex-linked dwarf gene in broiler production in hot-humid climates. Introduction of sex-linked dwarf gene especially in hot harsh tropical environments brings a great advantage for broiler production. The heavy broiler parent suffers due to the stress of these adverse climates. Sex-linked dwarf genes reduce body weight, egg weight, but are superior for adaptability under harsh tropical environments, with a lower requirement for housing and feed, better survivability and reproductive fitness giving fewer defective eggs, more hatching eggs, better fertility, hatchability, feed conversion efficiency and resistance to disease. Overall the cost of chick production from dwarf hens is lower than from their normal siblings. Market weights of broilers from sexlinked dwarf dams is almost similar to those of broilers from normal dams with normal sires. But the net benefit of broiler production from sex-linked dwarf dams is found to be greater than that of broilers from normal dams. This will be the most important to the rural communities in Bangladesh and in other countries where the similar environment and socio-economic conditions exist. Therefore, sexlinked dwarf hens might be used in broiler breeding plan as well as broiler production in the tropics.

The purpose of this paper was to study on the attitudes about Reverse-Mortgage among Baby Boomers to offer the basis for revitalization of Reverse-Mortgage. Social survey research using a questionnaire was conducted among the babyboomer's living in Seoul area from September $30^{th}$ to October $14^{th}$. The data from 102 respondents were analyzed using SPSS PASW 18.0. The main findings were as followings 1) although 64% of the respondents prefered to type which could withdraw temporary cash, but main factor that affected the use was a stability in one's old age 2) 72% of respondents thought adequate age for application was over 66. So lowering the qualification of age looked not need for revitalization 3) babyboomer's said that they would use reverse-mortgage if they couldn't get benefit from other pension inspite of getting lower recognition on house inheritance. It was be cause they regarded Reverse-Mortgage as a final step. In conclusion, current qualification and limit for withdraw looks adequate but it need public relations about its merit unlike other pension. And it has to emphasize its stability so that baby boomer can feel easy from holding a mortgage on their house.

Eater Seal, the child care experts, observes that children with disability significantly benefit from receiving appropriated care along side their peers. Typically developing children serve as role models from which children with disabilities learn age-appropriated communications and social behavior. Therefore the children with disability can actively participate in well-designed child care settings. But unfortunately in Seoul, Korea, only 2% of children with disability are taken care of in child care centers. And even the disabled children at the child care centers are mostly mentally or emotionally disabled because the building, programs and services of the centers are restrictive to the children with severe physical disabilities. This study reviewed Korean domestic physical environment of child care centers for children with disabilities. Questionnaire survey was conducted to 103 centers located in Seoul by mail. Our survey revealed that they need more areas for nursing room and special rooms and the accessibility to buildings has to be improved. Also, there are no elevators in all buildings surveyed. Accessibility to toilet is noted as significant problem, especially wet floors in toilets. In a nursing room, a space for psychological rest and special education is needed for children with mental disability. Technical specifications on how to make buildings and facilities accessible for the children with disability should be developed. The goal of this study is to provide basic information to develop domestic design guidelines to ensure that the child care centers are safe, convenient, and usable for everyone possible.

Although recently revised building code requires 15~20% increased thermal insulation performance for window systems, since the code is focusing on winter heat loss, it is not satisfactory to contribute on reducing rapidly rising cooling load in summer. Window systems have great impact on building heat gain and loss. Therefore technological development for window system specialized in shading solar gain in summer is an urgent matter. This study evaluates the performance of sun shading and thermal insulation for blind integrated window system. Also, computer simulation evaluates the effect of heating and cooling energy consumption reduction for an individual unit(floor area of $85m^2$) of a multi-family housing. Physibel Voltra, a heat transfer analysis software, was used to analyse the effect of energy consumption reduction, and the energy load was converted to the cost to compare the actual effect of economical benefit.

The objective of this study is to introduce the urban utility concept that combines urban growth and urban disasters in the aspect of a conceptual theory. While many studies focused on the dollar amount damaged from a disaster, it requires adding not just building damages or human body losses but also the quality of life satisfaction. An issue in measuring the quality of life satisfaction needs to introduce a proper mode quantifying it. This study introduces the urban utility change in measuring the negative impacts of a disaster on urban life, which has been rarely investigated. To identify urban utility, urban flooding that is a cross-sectoral agenda and important to both developed and developing countries was adopted to respond to its increased frequency and damages, encouraging governments to focus on flood control policies. By combining a literature review on urban utility and urban growth, this study defined the urban utility concept as a net benefit of a resident with earnings subtracting housing and commuting costs. The theoretical study also explained that urban utility and its components dynamically change as per urban growth and disasters that even reversely affect urban growth. Because the urban utility can be one of the useful indices to appreciate the relationship between a disaster and urban growth, it is highly expected to apply for similar disaster impacts on urban areas, including COVID-19 and various global warming issues.
