This study was directed to the Peizootics of Newcastle disease in Korea. Since 1960 New-castle disease epizootics have been observed at an interval of one or two years. The frequency of Newcastle disease outbreaks was related to the amount of the vaccine used, being the more sufficient vaccine produced the fewer outbreaks. Regional distribution of Newcastle disease outbreaks was most frequent in the capital area, being the center of poultry raising and Poultry product marketing, and infrequent in areas distant from the capital. Spreading of Newcastle disease appears to be mainly due to the movement of infected chickens. More than 60 percent of the total outbreaks of Newcastle disease diagnosed at the Veterinary Research Institute in Anyang were observed in young chickens aged less than 60 days. Improper vaccination, interference by maternally derived antibody with the immune response following vaccination, ana immaturity of immune systems of young chickens might have contributed to the results. This view was further supported by the findings that 23 percent of the total flocks experienced Newcastle disease were not vaccinated at all and, in vaccinated flocks, virtually all of the flocks were vaccinated by the drinking water method, which has been known less effective compared to individual application or spraying methods.

The analysis of groundwater quality in Kyungnam Province was conducted using monitoring results obtained during 1994. According to the analysis, most heavy metals and pesticides listed in Korean drinking water standards were not detected in Kyungnam Province groundwater, but arsonic and volatile organics such as TCE and PCE were detected. Four inorganic contaminants were detected and frequency of violating the standards was in order of $NO_3-N, F^-, As, NH_3-N$. Of organics, TCE and PCE were the only contaminants detected. TCE more frequently violated the standards than PCE. Correlation was investigated among contaminants detected in Kyungnam Province groundwater. The correlation results showed that high correlation existed among dissolved solids, hardness, and $SO_4^{2-}$.

Adolescents grow rapidly and have lots of schoolwork for entrance examination, so good nutrition is very important to them. However, adolescents tend to have a poor dietary behavior including frequent consumption of empty calorie foods and skipping breakfast. In particular, frequency of drinking milk has been low among Korean adolescents, thus their dietary calcium intakes has been low. Undesirable dietary behavior of adolescents is a risk factor for poor nutrition, obesity and chronic disease of them. Milk is a good source for calcium, high quality of protein, vitamin and bioactive compounds including anti-obesity component, thus it has been reported that milk helps improvement of dietary nutrient adequacy and physical growth, increment of bone mineral density, and prevention of obesity and chronic diseases. Therefore, milk consumption of adolescents should be encouraged in order to help their nutritional status, physical growth and health.

Objectives: The objective of this study was to investigate function evaulation and related factors in the elderly. Methods: Korean version of ADL and IADL were measured for 40 normal in the Elderly in July 15-20. 2000. Their ages were 65 or more in years. 14 items from Modified Barthel Index and 14 items from Modified Lambeth Disability Screening Questionnaire were used. Results: The frequency of disability was the highest in Heavy homework(85.0%) folliwed by Walking on level 50 yards or moer(5.0%), Up&down stairs for 1 flight(5.0%) in 28 items from Modified Barthel Index and Modified Lambeth Disability Screening Questionnaire. Conclusions: Results indicated that no smoking and drinking at onset had high Modified Barthel Index. Modified Lambeth Disability Screening Questionnaire was associated with age.

A study on the fouling control by periodical ozone-scrubbing was conducted in a membrane filtration process for drinking water treatment. Hydrophilic hollow fiber polyethylene membrane with pore size of $0.1{\mu}m$ and its surface area of $0.42m^2$ was used. Dead-End filtration method was selected to obtain high efficiency of energy. Laboratory prepared synthetic raw water with kaolin was used and the membranes were scrubbed by ozone once in an hour and once in two hours. When the duration of ozone scrubbing was increased from 10 seconds to 20 seconds, the rate of membrane fouling was significantly decreased. Although the frequency of ozone-scrubbing was reduced from once in an hour to once in two hours. the effect of fouling control was unchanged. However, ozone-scrubbing was not effective after a membrane was fouled and washed with detergent for reuse. Among several possible working effects of ozone, bactericidal effect was confirmed to be the primary reason of fouling control.

To investigate antioxidant status and platelet antioxidative enzyme activity in patients with ischemic heart disease, 36 male patients admitted to Kyungpook National University Hospital from June to December 1994 were compared to 36 healthy male control subjects. The percentages of heavy smoking and nonexercise were significantly higher in the patient group compared to the control, but the drinking status was not significantly different between groups. Food habit and food frequency scores were significantly lower in patients than in control subjects. Plasma retinol levels tended to be lower in the patient group, and plasma $\alpha$-tocopherol and $\beta$-carotene levels were not different between groups. There was no difference in the level of plasma thiobarbituric acid reactive substances(TBARS) and in the activities of platelet glutathione peroxidase and catalase. Our results indicate that oxidative stress, which is reflected by the plasma levels of antioxidants and TBARS, did not increase in the patients with ischemic heart disease, and the long-term effects due to smoking, poor food habit and other life styles could possibly contribute to the onset of the disease.

This study was aimed to evaluate any influence food habits food intake freqyuency and factors associated hair conditions. The subjects of this study consisted of 291 female college students in Chung Ju. Questionnaires were completed by them Eating habits of subjects was irregular and hair type was not good generally hair glossy was most Who had hair trouble. The relationship between hair type and eating habits was not significant. But the rate of hair troubles, fallen hair, white hair, glossy were lower at the fish and soybean intake frequency to increasrd.(p<0.05) The drinking trime of coffee(p<0.01) and alcoholic beverage(p<0.05) per day was significant negative correlation with hair growth.

Recently, occurrence of alcohol-involved traffic accidents is increasing while all the accidents by violation of law except drunk driving. Traffic accidents by drunk driving has a great external cost. In detecting drunk driving, blood alcohol content Many studies reported close correlation between blood alcohol content and traffic accidents by drunk driving. The risk of traffic accidnet increases exponentially as blood alcohol content increases. To control traffic accidents by drunk driving, decide target population. Heavy drinkers are few and responsible for a small part of the loss while casual drinkers are many and responsible for a large part of the loss. Casual drinkers need to be included in the targer population for the control of traffic accident by drunk driving. Stragegies to reduce the quantity of alcohol consumed, change the pattern of drink, such as frequency of drinking, raise of perceived risk of accident need to be sought.

Alcohol has been used as sedatives historically. The effect of alcohol on sleep is different according to its dose, timing of ingestion, and drinking frequency. Sleep problems may play a role in the development and course of alcohol-related disorders. Insomnia in alcohol-dependent patients is common and early treatment of insomnia may reduce the rate of relapse. Sleep apnea, restless legs syndrome, periodic limbs movement disorder, and altered circadian rhythm may be more frequent in this patients. Management of sleep and alcohol problems is important in treating alcohol-related disorder and sleep disorders, respectively.

To investigate effect of alcohol consumption characteristics on the body mass index (BMI) and blood pressure (BP), we performed statistical analyses of data from questionnaire survey among adults over 20 years old, using SPSS WIN program. Alcohol consumption characteristics such as frequency of drinking, amount and toxic degree of alcohol didn't show a significant correlation with BP. Amount of alcohol consumption and BMI showed a positive correlation (r=.264, p<.01). Waist circumference and BMI had the highest correlations with amount of alcohol consumption, which increased with aging.
