Laundery detergent ingestions are generally considered to have minor consequences. But some detergent ingestions have severe consequences. Unlike household bleaches contain sodium hypochlorite, bleaching agents that contain sodium carbonate have the potential to cause significant mucosal damage to the gastrointestinal tract if ingested. Especially, when ingested in solid form of Sodium carbonate, corrosive injury is much heavier. Therefore, patient who ingest sodium carbonate peroxyhydrate need more intensive management than patient who ingest other bleaches. We experienced a case of serious caustic injury after ingestion of Sodium Carbonate Peroxyhydrate. We report this case with review of literature.

1. CONTENTS (1) RESEARCH OBJECTIVES Urban regeneration is a progress to improve physical environments as well as environmental, economic, and social aspects of degenerated urban regions, to recover inactive function, and at the same time to recreate into competitive residential environments. More than 70% of hothouse gas are exhausted in urban regions. For the purpose of lessening hothouse gas and coping with changing weather, it is necessary to construct and promote low-carbon green urban regions with green energy. It is urgent to grasp problems and improvement to put into a triangular position models for developing low-carbon green urban regions through multi-angled examination. This study is aimed at examining the basis of a way to distribute new-material energy through urban region regeneration. (2) RESEARCH METHOD As a way to attain the aim, this study put into triangular position the conception of urban regeneration and newly recycled energy and examined the national as well as international status. In addition, this study investigated the possibility to distribute low carbon in urban regions through the cases of sunlight plant and small water-power plants. (3) RESEARCH FINDINGS It is necessary to approach low-carbon green urban regions theoretically as well as technologically. But, it has a weak point; it needs a lot of cost for investment in facility, because technology related with land and energy is not sufficient. It is possible to generate and distribute clean urban regions by removing the factor. 2. RESULTS Our country is dependent on importation of more than 97% to secure energy. So our country is very weak in energy security and on the7th rank in the world as a hothouse gas exhaustion country. It is possible very much for our country to be included in an obligatory country to lessen hothouse gas. In the status, it is necessary to expand the conception of consultation for environmental preservation and economic growth and to approach wide-conception including qualitative development of economy and society and value of green.
The chassis system of the mobile components is weakened by the inflow of dust particles. The inflow of dust particle weakens the durability of automobile’s components and also weakens the driving ability by increasing wear and friction in the rubber-seal components among the chassis systems. In this study wear characteristics and mechanism analysis of rubber-seal for the inflow of dust particles were investigated using the sliding wear tester. The tester is a type of ball-on-disk ; ball is a steel, disk is a rubber-seal. and We used five kinds of the amount of SiO₂ particles 0g, 0.5g, 1g, 1.5g, 2g 2.5g in water, because SiO₂ particle is a main ingredient of dust.
The chassis system of the mobile components is weakened by the inflow of dust particles. The inflow of dust particle weakens the durability of automobile's components and also weakens the driving ability by increasing wear and friction. in the rubber-seal components among the chassis systems, the inflow of the dust particle increases the wear and friction. Therefore those make the noise and have a bad influence on the mobile system. In this study friction and wear characteristics of rubber-seal for the inflow of dust particles were investigated using the sliding wear tester. The tester is a type of ball-on-disk ; ball is a steel, disk is a rubber-seal. and We use a SiO₂ and Al₂O₃ particles, because SiO₂ particle is a main ingredient and Al₂O₃ particle is second ingredient of dust.

1.CONTENTS (1) RESEARCH OBJECTIVES This study aims at investigating, through theories, real estate price and type changes according to city growth and at looking into how much development profits are output by analyzing correlative relation between city growth and real estate price. (2) RESEARCH METHOD The applied ways are to examine precedent studies through existing literatures and to look into the relation between city growth and real estate. (3) RESEARCH FINDINGS The study leads to the result that city space expansion has to be come true through developing existing city areas, and that the space effectiveness has to be optimized through linking functionally and unifying areas. 2. RESULTS It was found, in the course of city growth, that city inner-structure formation has a lot of influence on real estate price. First, in the future, city policies have to be changed from centrifugal city space expansion to centripetal city space re-structure. Second, in city development, effective space utilization has to be considered on mostly through restructuring existing city areas. Third, cities have not to be divided into spaces in connection with functional specification or functional major. In addition, city spaces have be harmonious with functional linkage or functional unification between old city areas and new city areas. Fourth, service spaces have to be supplied to assist economic city activities. 3. Key Words City Growth, Real Estate Price, development profits, analyzing correlative relation
