To investigate whether genistein regulates menopause-induced obesity, it was studied the effects of genistein on anti-obesity effects in female ovariectomized (OVX) mice, an animal model of postmenopausal women. 7-week-old female mice (C57BL/6J) were randomly divided into three groups. All the animals received a high fat diet or a high fat diet supplemented with genistein for 8 weeks and variables and determinants of obesity were measured. The OVX mice had significantly higher body weight and adipose tissue mass than sham mice. However, genistein supplementation reduced body weight, adipose tissue mass, and adipocyte size of OVX mice. The OVX mice treated with genistein had significantly lower levels of serum triglycerides and total cholesterol than the vehicle-treated OVX mice. Lipid accumulation in liver was also markedly decreased by genistein in OVX mice. The results suggest that genistein can effectively prevent adiposity, adipocyte phertrophy, and llipid disorders caused by ovariectomy. Moreover, this study may contribute to the alleviation of metabolic syndrome, including obesity and hyerlipidemia in postmenopausal women.

This paper is focused on the research of environmental and human factors for a design of PMVbased air conditioning system in the ship. In the results from environmental factor research, it is possible to dissatisfy thermally in the wheel house and communication room of 25 ton and engine room of 100 ton. The clothing and activity in the ship is modified using inland indoor characteristics. Thermal resistance of clothing may be more sensitive to PMV(predicted mean vote) than metabolic rate because of large deviation among maritime polices. The distribution of human factor is right long-tailed than standard normal distribution.

The kidney keeps with close relationship in the internal organs, that the kidney function filtering eliminate the wastes to the urine on the processing to replace the old with the new blood. In case of these problem in the kidney, there is no way to catch out with self-awakening symptom except for serious illness. This problem can solve with keeping the systematic diagnosis method in the kidney trouble shooting. Under the circumstances, the importance of the diagnosis for the kidney disease is growing day after day. In this paper, among the great four diagnosises, using the way of ocular inspection & auscultation, we would like to propose rouble shooting in the way of the kidney. To do this, through the assistance of the input image, extract the value of the color with appropriate output, analysing the color of the face with related to the kidney, using the results we would like to get the accurate symptoms on the kidney's problems. Also, through analysing and comparing with the relationship the kidney and the signal of voice, we would like to realize the proof system of human health. Finally, we'd like to make proof of the usefulness for proposed method from this study.

Microbial fuel cell (MFC) is the major of bio-electrochemical system which can convert biomass spontaneously into electricity through the metabolic activity of the microorganisms. In this study, we used an activated sludge as a microbial inoculum and then investigated the feasibility of using dairy wastewater as a possible substrate for generating electricity in MFC. To examine the performance of MFC as power generator, the characteristics on cell potentials, power density, cyclic voltammetric analysis and sustainable power estimation were evaluated for dairy wastewater. The maximum power density of $40\;mW/m^2$was achieved when the dairy wastewater containing 2650 mg/L COD was used, leading to the removal of 88% of the COD. The results from this study demonstrate the feasibility of using MFC technology to generate electricity while simultaneously treating dairy wastewater effectively.

Functional imaging based on the susceptibility only is achieved by separation of the susceptibility effect from the mixture of flow effect by use of a tailored RF pulse in conjunction with gradient echo sequence. Using the tailored RF pulse the susceptibility enhanced functional imaging appears to be explicitly related to the deoxygenation processes, while in the conventional gradient echo technique functional contrast on $T2^{*}$ effect images appear to be mixed with a significant fraction of blood flow (in- flow) signals of both arterial as well as venous bloods due to the nature of the fast sequence employed with the gradient echo technique. In this paper, using the tailored RF pulses, one can unambiguously separate the susceptibility and flow effects in functional imaging. Since the signal obtained can be made sufficiently high and represents oxygenation process more accurately, it seems possible to study quantitative oxygen metabolisms in brain function hitherto difficult to do with other gradient echo techniques.

The purpose of this study is to propose an effective exercise for the prevention of osteoporosis by analyzing changes in bone metabolism markers and adipocytokines according to the application of modern dance. The objects were selected between t-score -1.0 to -2.5 and subjects were random assigned to the modern dance group(n=10) and control group(n=10). Modern dance was held three times a week for 60min, for 12weeks. For data analysis, two-way repeated measures ANOVA was analyzed using SPSS. As a result of the study, both osteocalcin(p<.01) and T-score(p<.05) were significantly increased in the modern dance group. Adiponectin(p<.05) was increased significantly and Both TNF-α (p<.05) and IL-6(p<.05) were significantly decreased in the modern dance group. As a result, modern dance is considered to be an effective strategy to prevent osteoporosis, and it is expected to have a positive effect on metabolism and function improvement in elderly women with osteopenia.

As the effectiveness of ionic water that mainly used for the purpose of treatment has been widely known with the recent "well-being" trend, people's interest in it is also gradually increasing. Especially, the alkaline ionic water for drinking purpose could conveniently provide different types/amount of inorganics required for different dietary life depending on nature and race, could effectively provide alkaline inorganics that could be insufficient to modern Korean people, and also could provide alkaline inorganics that prevent/cure/relieve pregnant women's morning sickness. Applying the suggested performance/manufacturing method of alkaline ionic water through the performance assessment of alkaline electrolytic ionic water of the developed product, it would be necessary to have additional researches on the improvement of product or parallel development that could be applied to diverse areas.

This paper aims to examine the complexities of the state-nature relations in Korea by emphasizing the complex processes of interactions between the state and nature. In doing so, it relies on the literature of "political ecology of state-nature" which problematizes the conventional modernist views on nature assuming the dualistic separation between the state and nature. First, we critically review the existing Korean literature on the state-nature relation (e.g., the ecologism, the metabolic rift theory, the social construction of the nature, the green state thesis, etc.) and argue that these studies significantly lack the recognition of the interactions between the state and nature. Second, we discuss the possibilities of seeing the state-nature relations from the perspective of political ecology as an alternative approach to the state-nature relation. Last, we conclude that the political ecology approach to the state-nature can deepen our understandings of the Korean capitalist development.

A study for recovering of copper and lead from electronic scraps has been carried out using a combination of bioleaching and solvent extraction. It was found that the citric acid generated by Aspergillus niger could be an imporant leaching agent acting in the solubilization of copper, iron, lead and tin from the electronic scrap. Copper could be selectively extracted by 10% LIX84 from the leaching solution and it recoved 99.9% of metallic copper by electrowinning process. Tin and iron were extracted from the remaining solution by 10% Alamine336 and stripped by NaCl solution. Finally, tin could be recovered as a metallic precipitates from the mixed solution of tin and iron by cementation with iron powder.
