It's used to be said that tsunami is a rare event. The recurrence time of tsunami in Sumatra area is approximately 230 years as CalTech Research Group‘s study from paleocoral. However, the tsunami occurred in Indian Ocean on 26 December 2004, 28 March 2005 and 17 July 2006, because the earthquakes still release the energy. To cope with the tsunami disaster, we have to put the much effort on better disaster preparedness. The Tsunami Reduction Of Impacts through three Key Actions (TROIKA) was suggested by Eddie N. Bernard, the director of NOAA/PMEL (Pacific Marine Environmental Laboratory). They are Hazard Assessment, Mitigation and Warning Guidance. The satellite remote sensing has potential on these actions. The medium and high resolution satellite data were used to assess the degree of damage at the six-damaged provinces on the Andaman seacoast of Thailand. Fast and reliable interpretation of the damage by remote sensing method can be used for inundation mapping, rehabilitation and housing plans for the victims. For tsunami mitigation, the satellite data can be used with GIS to construct the evacuation map (evacuation route and refuge site) and coastal zone management. It is also helpful for educational program for local residents and school systems. Tsunami is a kind of ocean wave, therefore any satellite sensors such as SAR, Altimeter, MODIS, Landsat, SPOT, IKONOS can detect the tsunami wave in 2004. The satellite images have shown the characteristics of tsunami wave approaching the coast. For warning, satellite data has potential for early warning to detect the tsunami wave in deep ocean, if there are enough satellite constellation to monitor and detect the first tsunami wave like the pressure gauge, seismograph and tide gauge with the DART buoy can do. Moreover, the new methods should be developed to analyse the satellite data more faster for early warning procedure.

In this study one aspect of consumer behavior in household equipment utilization was investigated the pattern, frequency, rate of washer use and their relation to the following factors a) Washer related factors : extent of the presence of desired characteristics, the evaluation of washer's intrinsic features and related household facilities. b) Psycho-social factors : attitude of energy conservation, preference & ability to wash by hand, standard of washing of the respondent homemaker. c) Socio-demographic factors : age, education level and employment status of homemaker, house-hold income, the presence of children under seven years, size of family, the presence of a paid help. The subjects of this study were 286 homemakers with washer in Seoul. Analysis methods were used to fuequency, one-way ANOVA, Gamma test, Pearson's Correlation Coefficient, t-test and multiple regression of SPSS program. The major findings are the following; 1) The pattern, frequency, rate of washe use appeared various in every household. 2) Extent of the presence of desired characteristics was very low and respondents evaluated their washer's intrinsic features moderate. 3) The pattern of washer use was affected by the evaluation of washer's intrinsic features, preference & ability to wash by hand, wife's employment and household income. The frequency of washer use was affected by family size and preference & ability to wash by hand. The rate of washer use was affected by extent of the presence of desired characteristics, the evaluation of washer's intrinsic features and preference & ability to wash by hand. Therefore, washing by hand is major substitute for washer. If more desired characteristics are added to washer, intrinsic features are improved, and maintenance costs are reduced or household income is raised, every houshold with washer will use washer more than washing by hand in washing ask so that it may gain more utility from washer.

This study examines the effects of a low-calorie raw juice diet on the level of serum ferritin in adults and analyzes nutrient intake from the diet. There were significant differences between juices; the highest calorie was provided by pear juice, highest crude protein, vitamin A, and vitamin B2 levels were from green Juice 1; and highest vitamin C and vitamin B1 levels were from fruit juices. The ratio of estimated energy requirements (EER) for the participants was 56.2% from the raw juice diet. The percentages of recommended intake (RI) from the raw juice diet of protein (57.9%), dietary fiber (19.1%), niacin (6.2%), calcium (0.1%), and magnesium (0.2%) were lower than 75%. However, those of RI of vitamin A, vitamin B1, vitamin B2, vitamin B6, and vitamin C were 1796.5%, 7481.7%, 1915.5%, 30858.7%, and 7500%, respectively, exceeding the tolerable upper intake level (UL) for vitamin A, vitamin B6, and vitamin C. There were significant decreases in weight, the body mass index (BMI), body fat mass, and skeletal muscle mass in males and females. After the diet program, serum iron and SOD (superoxide dismutase) showed significant decreases, whereas RBC, hemoglobin, hematocrit, and serum ferritin showed significant increases. There were negative correlations between serum ferritin and weight and between serum ferritin and skeletal muscle mass for all participants. There were negative correlations between serum ferritin and skeletal muscle mass for males and between serum ferritin and body fat mass for females. These results suggest that a raw juice diet can supplement a regular diet to prevent excess or deficient nutrient intake.

The relationship between level of milk composition and conditions of ovary and uterus were analyzed in Holstein cows at seven farms participating in a reproductive herd health management program. Milk data were taken from 503 early lactating cows between 30 and 60 days in milk with reproductive examination with ultrasonography from september 1999 to August 2000. Milk fat, protein and solid-not-fat concentration in the herds were $3.70{\pm}1.08%$, $2.97{\pm}0.35$, and $8.41{\pm}0.61%$, respectively. The reproductive disorder relative to normal cows had higher risk in the cows that the level of protein was lower than 2.70%. Also, the higher milk fat than 4.50% were associated with a higher risks in the uterine disease and follicular cysts. Therefore, the cows with the fat to protein ratio of > 1.30 had higher risks for reproductive disorder such as cystic ovarian diseases, inactive ovaries and endometritis. These results indicated that cows diagnosed with reproductive disorder were energy deficient prior to reproductive disorder diagnosis. Consequently, milk fat and protein analyses may be used serve as a monitoring tool for condition of ovary and uterus in early lactating cows

기후변화 대응 및 에너지 안보를 위해 세계 각국에서는 다양한 재생에너지 보급 정책을 수립, 시행하고 있다. 재생에너지 정책이 재생에너지 확산에 미치는 영향을 분석하는 많은 선행연구들에서는 종속변수로 재생에너지 발전량을 사용하고 있는데 자기상관(autocorrelation) 문제의 발생 가능성에도 불구하고 정태적 모형을 쓰고 있다는 점, 기술채택에 선행되어야 하는 기술혁신의 영향을 고려하지 않았다는 점에서 한계점을 지닌다. 본 연구에서는 동적 패널 모형(dynamic panel model)을 이용하고 기술혁신 변수를 추가함으로써 위의 두 한계점을 극복하고자 하였다. 분석 결과 FIT가 RPS보다 재생에너지 보급에 보다 효과적임을 알 수 있고, 재생에너지 기술혁신 또한 재생에너지 확대에 긍정적으로 기여한다는 사실을 밝혀내었다. 또한 이 결과를 바탕으로 기존 선행연구에서 공통적으로 직관과 어긋난 결과를 도출한 데에는 위의 두 한계점이 원인일 수 있다는 가능성을 확인하였다.

This study was intended to investigate the risk of metabolic syndrome (MS) in healthy 92 male smokers (mean age: $44.4\;{\pm}\;7.8\;yrs$). We investigated the anthropometric assessment and dietary intake survey for 2 days by 24-recall method, also blood pressure and serum lipids were measured. The average numbers of cigarettes smoking a day were 21.3/d, smoking duration were 21.5 years. The proportion of fat energy was 24.9% and intakes of vitamin B2, folate, calcium, potassum and fiber were lower than KDRI. The body mass index (BMI) and body fat % were 24.8, 23.9% respectively. The systolic ($134.1\;{\pm}\;1.4\;mmHg$) and the diastolic blood ($87.9\;{\pm}\;1.1\;mmHg$) pressure were in borderline hypertension. Among biochemical parameters, TG ($173.6\;{\pm}\;9.4\;mg/dL$) and fasting blood glucose ($109.0\;{\pm}\;2.4\;mg/dL$) levels were out of normal values. The most occurred problem among the risk factors related to MS was the borderline hypertension (63%) in subjects. Regarding the correlations of anthropometric data with biochemical factors, TG was significantly correlated with the BMI, body fat % and waist circumference. Smoking years showed positive correlation with AI. These results suggest that the smoking habit has significant relations with the risk factors of MS. Therefore, quitting is necessary to prevent MS, and nutrition education and dietary management program are required to prevent the degenerative disease.
