In Korea, the apartment supplier should satisfy the apartment residents' demand on the defect repair found in apartment housing by the law of Management of Apartment Complexs. But in the cost of defect repair, not only the actual defect repair cost, but also the cost of residents' complains are contained. So in this analytic study, the actual use state of defect deposite during 4~10 years after moving in are analysed base on actual data of 15 apartment complexes. In this study, about 66% of defect repair deposites are used to actual defect repair and only 34% of defect repair cost are spent to satisfy the demand of apartment residents'.

A comparative study on the effects of the water fluoridation program and fluoride mouth rinsing program in the elementary school children. This study was performed to compare the oral health status of permanent teeth for children of the caries prevention effects by using methods of fluoride 309 children for water fluoridated program, 240 for fluoride mouth rinsing program and 248 for control group. The DMFS rate, DMFT index, soft and hard deposite rate were analysed from the oral examination. And 300 questionares from the parents who lived in Cheong ju city were evaluated to see the situations of using the tap water. The results were as follows; 1. Caries experience rate in permanent dentition was the lowest in fluoride mouth rinsing group. 2. It was estimated that soft deposite rate was comparatively low in the fluoride mouth rinsing group but calculus deposite rate was no significant difference in each other groups. 3. The 72.0 percentage of parents who lived in non fluoridated water area were misunderstood that they lived in water fluoridated area. 4. The 66.8 percentage of residents used the piped water as drinking water. 5. It was recommended that fluoride mouth rinsing program was suggested in rural area, on the other hands, toothbrusing program in urban area with water fluoridation to prevent the dental caries for school children.

The Aggregation State of thin vapor deposite Film made by Cyanine Dye were changed into Monomeric molecular state(M) and Dimeric Aggregation(D) at the acidic treatment, into reversible H-Aggregation (H) at alkalic gas or heat treatment. Photo-electric properties were higher H than D and M, this stats were effective in enhancing Photoelectric-conversion characteristic. Substitute group of Meso-Position being stronger electronic Donors, Electronic density is higher and Electric conductivity is enhanced, we confirmed Oscillator Strength calculated by PPP-Molecular Orbital Calculation and Absorption Spectra at solvent stats were agreed good.

Time series data on the size of Chonsei deposit has been estimated. At the end of 1997, that size has been estimated as 112 trillion Korean Won. If the Chonsei system can be moved toward the monthly rental system, it is highly probable to achieve the Pareto imporvement whether there are uncertainties or not. The new system named as the Chonsei system without the Chonsei deposite has been suggested, which can be readily to be introduced. Under this system, the owner can sustain opportunitities of using Chonsei deposit, renters can rent houses whithout the Chonsei deposity and financial intermediaries can secure safe sources of loans, which will increase BIS capital ratio of banks.

Direct electrostatic coating method is simple, low cost and environmentally useful method. We are investigated on the coating of carrier transfer polymer layer on the carrier generate inorganic pigment layer using direct electrostatic coating method. The sample was obtained electrostatic deposite layer by fusing and calendering on the copper phthalocyanine. we could be found several polymer thin film shows good bond properties between film and pigment layer.

Most soft ground in the southern and western coasts in Korea consists of very compressible alluvial deposits. Four samples in these alluvial deposite were selected to manifest the constitutive relations of consolidation. A series of tests were performed to investigate void ratio -effective stress relationand void ratio-coefficient of permeability relation on soil samples obtained at Haenam. Jindo Mankyung and Janghung permeabilities by CRS thoery were similar to directly measured data but those of indirectly computed by $C\upsilon$ shows difference. Several models about compressibility and permeability were compared with test data.

Under the law of Management of Apartment Complexes, the Apartment Supplier should satisfy the demands of residents for the repair of defects found in Apartment Housing. But in the cost of defect repair, the expense of resident complaints is not included, and only the actual defect repair expense is counted. So in this study, the actual use state of defect deposits for 3 years after moving in is analyzed based on the actual use data of 39 apartment complexes. The study shows that more than 50% of defect repair deposits are spent to satisfy expenses arising from complaints by residents. This is not only caused by irrational demands of residents, but also by the adoption of a stopgap policy by Apartment Suppliers.
