Korean funeral customs are an important part of the mourning process in Korea. A survey was conducted in the southern part by the Nak-dong river, centered around the city of Busan to examine Korean funeral rites. This study was conducted with survey research. The target population included 234 teachers and experienced the death of a family member within the last three years. Results showed that they presented their condolences 5 to 6 times on average per year. Funeral rites were performed usually at a hospital funeral hall. The preference of burial to cremation was about the same. According to the survey, funeral expenses averaged 9,570,000 won and donations received for funeral expenses, 12,630,000 won. Problems the respondents expressed about the process included large funeral expenses, the decision whether to bury or cremate, and fatigue from staying up all night. When classified according to the demographic characteristics, there were significant differences in the variables. Frequency of attending funerals depended on gender, age, and health status. Condolence style depended on religion. The type of funeral (burial or cremation) depended on family income. The type of reception depended on gender. Funeral expenses depended on the age Second, in the process of preparing for a family member's death, they thought it was important to prepare a funeral ceremony portrait of the deceased and a scroll by themselves, and the preparation

In this study, a series of direct shear tests were performed to investigate the characteristics of friction angles for sands and interface friction angle between sands and construction materials with respect to different relative density of the Nak-dong River sands and shearing velocity. The result of the test shows that friction angles of sands are always higher than interface friction angle between sands and construction materials. As the shearing velocity get faster, the friction angles of sand became higher. With respect to the density of sand by reducing void ratio, friction angles increase linearly, and relevant equations were proposed to calculate the friction angle by changing void ratio and relative density of sand. The interface roughness of construction materials was also an important factor in interface friction angle.

This thesis is to analyze characteristic of sustainable development in the Nak-dong River. The results are summarized in the followings. 1) The principles which did not consider the equilibrium between development and environment, ecosystem, security. precautionary measure, equity could devise a plan, changes of economic land area, sand & gravel extractions from the riverbed, the river contamination cleanup, dam build 2) The rules which disregard polluter pay and opening participation in public affairs could input of too much province budget and manpower, project team. The measures to solve these problems could be proposed expansion of environmental infrastructure, sustainable sand & gravel extractions from the riverbed, fortifying the assistance of the residents who live in Dam construction site and the peripheral area of Dam, lower local fund rates in national projects, and the creation of management organization.

In order to examine the corrosiveness of tap water, we studied methods calculating various indices including calcium carbonate saturation indices, using RTW model and LPLWIN model. Indices such as LI, RI and AI could be computed using the RTW model, whereas the LPLWIN model could find indices as LI, LR and CCPP. With water quality data obtained from tap water of Han River and Nak-Dong River watersheds, based on the indices found from the models, the water quality of the Nak-Dong River is better than that of Han River in the point of resisting corrosiveness. Further, the water quality of winter is highly corrosive than that of summer, as long as the temperature rises up, the corrosiveness is reduced.

This paper is focused on studying the undrained cyclic triaxial behavior of saturated Nak-dong River sand, using anisotropically consolidated specimens. A test of isotropically consolidated specimens was performed to compare the results of the anisotropically consolidated specimens. The cyclic shear stre3ngth of the sand under various combinations of initial static shear stress and relative density was considered. Failure was defined as a 5% double amplitude cyclic strain and a 5% residual axial strain for both reversal stress and no reversal stress conditions. Using this definition, the cyclic strength of the anisotropically consolidated specimens was affected by the initial static shear stress. For anisotropically consolidated Nak-dong River dense sand, the cyclic strength is greater than that of Toyolura silica sand but is smaller than that of Dogs Bay carbonate sand. By comparing the experimental and predictecl results, it was possible to predict the residual pore pressure of Nak-dong River sand using Hyodo's model with initial static shear stress subjected cyclic loading.

In this paper a determination of the optimal segment sealing material for a tunnel under the Han river between the Sungsoo-dong, Sungdong-Gu and the Chungdaw-dong, Kangnam-Gu in the Bundang railway. The geological investigation results show that some fractured zones exist loca]]y under the northern boundary of the Han river bed, but the other regions consist mostly of hard rocks of good Quality in the tunnel excavation level. Also, a hign water pressure of $5kgf/cm^2$ and a flash inflow of river water due to old boring holes are expected during tunnel excavation. A combined type sealing material of EPDM gasket with expansional rubber is selected as a optimal segment sealing material for the Han river tunnel considering the geological and site conditions.

Based on the results obtain from the investigation of Nak-Dong River District, it was classified as very thick, soft soil deposit. Furthermore, during the construction of structures large settlements are expected. Since large settlement affects the structures life, it is very important to accurately determine the consolidation of soil based on the obtained results. In this study piezocone test and laboratory test were performed to determine the consoildtion properties of Nak-Dong River District Pusan, Gyeong-Nam province. Degree of consoildation and the coefficient of consoildation obtained from the data of piezocone test and the results of the Oedometer test were compared and analyzed. Using the results the porewater pressure coefficient($B_q$) was obtained and the relationship with the Plasticity Index was also determined. From the results of this study the effects of the degree of consolidation and consolidation coefficient, and the porewater pressure coefficient and the Plasticity Index was determined.
