Leaching and adsorption equilibria of Sr Chemical Species from the near field of a repository has been studied in solidified cement with Fe and oxidized Fe. The absorption percent, Ads %, and distribution coefficient, K_(d) were calculated using equilibrium concentration to predict the extent of leaching and adsorption. In the mixed aqueous solutions the Ads % increase as Cement(C)/Water(W) ratios increase and K_(d) was decreased for Sr. These behaviors were discussed by adsorption and equilibrium of spiked ions. Oxides Fe promoted the adsorption of spiked ions, but pure Fe had no effect. E_(h) values were also estimated and discussed to elucidate oxidation-reduction environment of experimental system.

Experiments were conducted to get a better understanding of the rebound trajectory of impinging particle on a Flat Plate. The particle motion along the jet centerline relating to particle diameter impinging on a flat plate was visualized by using laser and a digital camera. The jet Reynolds number was 3300 and 8700, and glass beads of 30, 58 and 100㎛ in diameter were used. The photographs of particle motion trajectory show that one is impingement and rebound, which depends on the momentum of particle; and the other, which depends on the particle diameter and entrainment velocity of environment air during the second-impingement. The rebound height of particle increased with increasing particle diameter.

This study researches for the area source of granites used in the Mireug Temple site by the following three processes: observation by the naked eyes about 120 samples of granites in the different places of Iksan area, observation the samples in thin section through a polarizing microscope, and chemical analysis of major and trace elements according to the weathering stage. The granites of the pagoda has plenty of medium-grained granite with biotite, which is also seen in those of Mt. Mireug and Mt. Samgi. On the other hand, the observation of the flakes does not make any differences. According to the chemical analysis, the content of major oxide elements of the granites in the pagoda is the most similar to the one in the breast of Mt. Mireug, and the content of trace elements is also to the one in Mt. Samgi and the breast of Mt. Mireug. Additionally, considering the degree of weathering, the granites in the breast of Mt. Mireug contain the most similar content of oxide elements to the ones in the pagoda. In conclusion, the granites in the breast of Mt. Mireug can be considered to be the material of the Stone Pagoda of Iksan Mireug Temple Site.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

The present study was to investigate the effect of sport activities on adaptive bahavior in mentally retarded children; and to present some effective data for rehabilitation and education of the handicapped. After assigning 19 educable mentally retarded children to either experimental group(9 children) or control group(10 children), aquatic exercise treatment(60 min/day, 3 times/week) was administered for 12 weeks. Results were as follows. There were significant increases of personal self-sufficiency(p<.001), community self-sufficiency(p<.001) and personal-social responsibility(p<.001) and significant decrease of social adjustment(p<.001), but not in control group. It was found that sport activities had positive effect on adaptive behavior in obese mentally retarded children.

All dwelling complex should be plan with the consideration on the cars. this is because the car is no only a necessary tool for the man's various wants, but also a checking cause for the dwelling complex's comforts. this study focuses on the apartment complex of the dwelling scale taking a large percentage in Kwangju, and the various matters and the remedy about the parking space. the results are following. 1. The parking space is affected by the dwelling bwelling's arrangement, the open space and the incidental facilities. therefore the apartment complex plan of the future must apply the view of mass space. 2. Recently, the environs of the dwelling building are used as a parking space. It affects a bad effect on the complex's comfort. So the laws enacted to establish the underground parking place are required. 3. For the great comforts and closeness, the complex's plan has to consider the closeness of the complex entrance, the dwelling building entrance and the parking space.
