본 연구는 실내공기와 상수의 수질개선을 위하여 소형 평판형 오존발생기(plate-type ozonizer: PTO)를 개발하여 그 특성을 규명한 논문이다. 평판전극의 크기, 개수 및 배치에 따라 다양한 형태의 오존발생기가 고안되었다. 각 형태의 오존발생기의 방전 면적은 60[cm²]로 동일하며 방전전력은 최대 30[W]이다. 주요 연구 대상은 방전전력 오존생성농도 특성, 방전전력-오존생성수율 특성, 유량-오존생성능도 특성 및 유량-오존생성수율 특성이다. 오존생성특성은 PTOL-P가 가장 우수하게 나타났으며, 나머지 3종류의 오존발생기 (PTO<SUB>P-P</SUB>, PTO<SUB>C-P</SUB>, PTO<SUB>T-P</SUB>)에서는 유사한 결과를 얻을 수 있었다. It is the paper that this study develops the small plate-type ozonizer(PTO) for improvements of indoor air and water, and investigated the characteristics. Electric discharge area of ozonizer of each form is same to 60[cm²], and discharge power is the maximum 30[W]. Ozonizer of various forms was devised according to size, numbers and arrangement. The main study object is discharge power-ozone concentration characteristics, discharge power-ozone yield characteristics, amount of gas flow-ozone concentration characteristics and amount of gas flow-ozone yield characteristics. PTOL-P appeared so as to be most excellentm and ozone generation characteristics were able to get the similar results at three kinds of remaining ozonizer (PTO<SUB>P-P</SUB>, PTO<SUB>C-P</SUB>, PTO<SUB>T-P</SUB>).

For many years oxygen and hydrogen isotope analysis have been used as one of the most valuable research tools to investigate many geological processes. There are many sample preparation techniques of oxygen and hydrogen isotope analysis for various geological samples. We introduce here several important sample preparation techniques for oxygen and hydrogen isotope analysis and discuss the problems of each method in detail.

The purpose of this study was to verify the effect of 12weeks aerobic exercise on inflammatory factors(high sensitivity C-reactive protein; hs-CRP, Erythrocyte Sedimentation Rate; ESR, white blood cell; WBC, Fibrinogen) and anti-inflammatory factors(Adiponectin, tissue plasminogen activator; t-PA) in elderly women. The subjects were divided into two groups; exercise group(n=12), control group(n=12). In exercise group, line dance were performed 60minutes a day, 3 times a week during the 12weeks program. The results were as follows; First, in the exercise group, significant decreased on hs-CRP and fibrinogen after the training, also, significant difference found on hs-CRP compared to that of control group, however, tendency of decreased ESR and WBC showed but no significant differences on it. Second, there are significant increased on adiponectin in exercise groups, and it increased compared to that of control group. However, no significant changes on t-PA. Consequently, aerobic exercise was effect on improvement of both inflammatory factors and anti-inflammatory factors, so that it can be reduce the Coronary Artery Disease(CAD)-related risk in elderly women.
