The purpose of this study was to investigate differences in the body composition, dietary habits, daily intake of nutrients and clinical blood indices in female college students by body mass index of normal weight, overweight and obese. The subjects of this research were 141 respondents of a survey carried out on students, and subjects were given 60 minutes to answer questionnaires, by recording their own answers. The average heights and weights of subjects by BMI were 162.17 cm, 52.73 kg in normal weight group, 162.35 cm, 62.22 kg in overweight group and 161.72 cm, 69.82 kg in obesity group, respectively. As for the survey daily of meals, starving breakfast and kind of snacks of subjects were significantly different among the groups by BMI. In animal protein food intakes, meat intake was the highest 'every day' food consumed by subjects, and there was a significant difference in distribution of BMI among subjects. Fruits, and greenish and yellow vegetables intakes were the highest 'every day' foods indicated by the normal weight group. Consumption of carbonated beverages and juices showed a significant difference among groups by BMI. The average of total-cholesterol was the overweight group was the higher value. There was a significant difference in diastolic blood pressure and systolic blood pressure among the groups by BMI. Average daily calories intake levels were insufficient and the intake ratio of carbohydrates, protein, and fat was the normal weight group 68 : 17 : 15, the overweight group 64 : 18 : 18 and the obese group 73 : 14 : 13. Results of the daily vitamin intake analyses displayed riboflavin, niacin, vitamin C, and folic acid levels lower than the RI levels. Fe intake was the normal weight group 81%, overweight group 76%, obese group 59% of the RI level. Therefore, it is necessary for college students to establish regular meals, good quality snacks and consuming more vitamin and mineral nutritions for optimal health conditions.

Background: This study used pre-hepatitis A vaccination era data in U.S. to study the relationship between serum hepatitis A antibody positivity with pancreas cancer mortality in adults. Patients and Methods: Public use National Health and Nutrition Examination Survey (NHANES III) data were employed. NHANES III uses complex probabilistic methods to sample nationally representative samples. Household adult laboratory and mortality data were merged. Sample persons who were available to be examined in the Mobile Examination Center (MEC) were included in this study. All results were obtained by using specialized survey software taking into account the primary sampling unit and stratification variables and the weights assigned to the sample persons examined in the MEC. Thus they are representative of the U.S. population. Results: The mean risk (95%CI) of death in the study population for pancreas cancer was 0.0014 (-0.000069 -.0029); their mean age (95%CI) at the mobile examination center (MXPAXTMR) was 473.43 (463.85-482.10); the follow up in months from their medical examination (permth_exm) was 170.12 (164.17-176.07). The odds ratios (S.E.) of the statistically significant univariables were: age, 1.007 (1.005-1.009); serum anti-hepatitis antibody status, 0.038 (0.004-0.376); and drinking hard liquor, 1.014 (1.004-1.023). The coefficients (S.E.) of the statistically significant variables after multivariate analysis were 0.006 (0.002-0.010) for age and -2.528 (-4.945--0.111) for serum anti-hepatitis A antibody negativity (using serum anti-hepatitis A antibody positivity as a reference). Conclusion: Serum hepatitis A antibody positivity correlates with higher pancreas cancer mortality in adults.

Recently, the demand of sewage treatment facilities have increased by growing the population growth of city and industrialization. However, most of public sewage treatment facilities lack the preparations of design criteria by increasing sewage water amount in the future. In order to respond to this situation, the government has consistently promoted the sewage treatment construction project. This study conducted a survey targeting residents and sewage treatment facilities, civil engineering a VE project professionals for effectively operating the sewage treatment facilities and improving its value to be built in the future. Based on this survey, this study will introduce the list of performance measurements which can not only save cost but also reflect opinion of users and residents. In addition, using Multi-Level Performance Measurement and AHP analyzed the weights of performance measurement which is more objective than existing things for applying efficient VE process

One-to three -month-old infants(n=252) were compared their growth performance(weight, length, head circumference, chest circumference) by feeding methods in cross-sectional study. There were two groups : breast-fed(BF) and formula-fed groups(FF). The weights of infants at 1, 2, and 3 postpartum month were 4.50$\pm$0.48kg, 5.76$\pm$0.62kg and 6.67$\pm$0.68kg, respectively. The weigh of male infants was higher than females. The length were 53.7$\pm$2.6cm, 57.4$\pm$3.3cm, 61.1$\pm$3.1cm at one to three postpartum months, respectively. The length of male infants was higher than females, too. Overall there were no significant differences between feeding methods in weight, length, head and chest circumferences, and monthly weight and length velocity. But 3-month-old formula-fed male infants showed bigger significantly in weight, monthly weight velocity and chest circumference than the breast-feds. By Korean standards, weight-for-height Z-score were distributed from 0 to ＋2. Not only was there a few malnourished infants but also overnourished were noticed, especially in formula-fed group. From this survey, long-time survey on growth and development of large scales might be necessary to determine the effect of feeding methods of infants after 3 months and to set proper grwoth standard for infant. And it was suggested the that the careful attention of polarized nutritional problems of early infants was needed, especially in formula-fed group. (Korean J Community Nutrition 2(1) : 3~12, 1997)

This research involved a survey on the dietary patterns of children and adolescents living in group homes, to find out their wrong eating habits and to devise measures for correcting their problems. The BMIs of the subject children and adolescents in group homes were measured, and the result showed that although many of them appeared to have normal weights, about 42.2% were actually underweight. Most of them had meals regularly, three times a day at fixed times. However, half of them frequently skipped breakfast because of the lack of time in the morning. In addition, more than half of them had the habit of having imbalanced diets, especially with low vegetable intake. The score for their satisfaction toward meals at group homes were highest (3.97) with the taste of food, while it was relatively lower (3.61) with the variety of food than with the other items. The average score for their snack intake was 3.47, showing that the majority of them had the habit of eating snacks, while the largest portion (26.0%) of them preferred bread and cookies. According to the result of the analysis on their food intake, overall calorie intake was about 82~96% of estimated energy requirements, while that of the male subjects aged 12 or older was about 82% of the standard energy requirements. Their overall intake of calcium and potassium was lower than recommended nutrition intake, but sodium intake was higher than 3 times recommended intake. Especially, in addition to calcium and potassium, the male subjects aged 15 or older showed low intake of dietary fiber, iron, zinc, riboflavin, niacin, vitamin C and folate also; whereas the female subjects aged 15 or older showed low intake of iron, zinc, riboflavin and folate also. Taken together, it was concluded that government level of dietary life-related support and management would be necessary for the healthy growth and development of children and adolescents in group homes.

The purpose of this research of this research was to survey the health of 181 male and 130 female students at K University in Chunganm from June 1 to June 23, 2001. It analyzed the students’dietary behaviors, life styles and perceived body shapes and the correlation of these factors to the health condition of the students surveyed. The results of the survey are summarized as follows. The average nutrition knowledge score (out of a possible 20 points), dietary attitudes score (out of a possible 50 points) and dietary habits score (out of a possible 30 points) were 8.66, 33.14 and 19.02 for males, and 9.99, 32.64, and 19.05 for females, respectively. The percentages of those who smoked, drank, smoked and drank and exercised regularly were 55.2, 92.8, 54.1, 82.9% for males, and 6.9, 91.5, 6.9, 63.1 for females, respectively. A significantly higher proportion of males smoked, drank, and exercised as compared to females (p<0.001). The percentages of students who were underweight, normal or overweight by BMI were 5.0, 79.0 and 16.0 for males, and 20.0, 78.5 and 1.5 for females, respectively. Fifty percent of females indicated that they felt they were obese, versus only 31.1% of males. Half of the females thought they were fattish, while only 31.1% of males thought that. Seventy-six point nine percent of females and 61.9% of males, more females than males, were dissatisfied with their weights. The health scores (the higher the point, the better the health condition) of the females (44.17) were significantly lower than those of the males (47.17) (p<0.001). A stepwise multiple regression analysis with health scores as the dependent variable and other scores as independent variables, indicated that the health scores of males were highly correlated with satisfaction with his body weight, smoking and drinking, and perceived body shape, whereas the females’health scores were highly correlated with obesity level, satisfaction with her body weight, and smoking and drinking.

Objectives : Weights and measures (度量衡) in Korean traditional medicine have been changed in many dynasties and countries. Thus, measurements of chon (寸) and cheok (尺) have been considered as symbolical meaning in recent studies on meridians and acupoints. The present study was made to settle up standard measurement by surveying length of each parts of upper limb as follows. Methods : To calculate length of 1 chon (寸), the length of each part was divided into the numbers of chon (寸) as shwon in ${\ll}$Goldo Hwangjenaegyeong-yeongchu (靈樞 骨度篇)${\gg}$; the chon (寸) length in ${\ll}$Goldo Hwangjenaegyeong-yeongchu (靈樞 骨度篇)${\gg}$ was compared with the chon (寸) length which is calculated by dividing human average hight into 75 chon. Results : Increment of length of 1 chon (寸) did not change as increment of height in subjects. Length of 1 chon (寸) in height is representative of length of 1 chon (寸) in each parts of upper limb. Conclusions : We suggest that most suitable length of 1 chon (寸)for the standard measurement of acupoint location is 2.20 ${\pm}$ 0.17 cm based on length of elbow joint to wrist joint.

Nutrient intake data collected by both dietary methods of the 24 hour recall method and the food frequency method from 538 middle school students were analysed to investigate any measurement errors occuring while using these methods. Measurement errors were observed both in terms of differences of average intake and consistancy from the two sources of data used. Wilcoxon signed ranks test was used to test the differences between the two average intakes and Speraman's rank order correlation coefficient was used to test consistancy. As a result, average intake value estimated from the food frequency method tended to be higher than that from the 24 hour recall method. The degree of overestimation varies from one nutrient to another. For instance, carotene showed not only the most significant differences in average intake but also showed the most incoisistancies between the two sets of data. This may imply the validity of nutrient intake as derived from different dietary survey methods varied from one nutrient to another, therefore the selection of dietary survey methods has to be made more cautiously in the case of certainnutrients.

During drought, there have been a number of conflicts because of the limited and insufficient water to allocate for the numerous water users. To solve the problems, the decision on the priority of water use should be made with social rationality A rational and systematic procedure needs to be implemented in order to decide the priority of water use. First, a criteria level is made of the main and detailed drought impacts which come from the economic, environmental, and social aspects. Four alternatives are then identified for priority of water use. Second, survey to the two group(professional, residents) has been done with using pair wise comparisons. Finally, the relative weights and the priority of alternatives are determined by means of the Analytic Hierarchy Process(AHP) which is one of the Multi-Attributed Decision Method(MADM). By using AHP, it has been concluded that the water allocation during drought should be accomplished in order of domestic, irrigation, industrial, and river maintenance water. If the AHP method were improved for inconsistency which may be generated with survey analysis, a number of applications will be used for the solutions of problem in water resources systems.

In this study, priority for groundwater contamination management was assessed based on regional vulnerability in Goyang-si area, Gyonggi-do, Korea using analytic hierarchy process (AHP) and geographic information system (GIS). We proposed a concept for regional vulnerability to groundwater contamination with using socio-environmental vulnerability factors, which can be classified into three properties including regional hydrogeological property, contamination property, and groundwater use property. This concept is applied to Goyang-si area. For AHP analysis, an expertise-targeted survey was conducted. Based on the survey, a total of 10 factors (criteria) and corresponding weights for regional vulnerability assessment were determined. The result shows that regional contamination property is the most weighted factor among the three property groups (hydrogeological property: contamination property: groundwater use property = 0.3: 0.4: 0.3). Then, database layers for those factors were constructed, and regional vulnerability to groundwater contamination was assessed by weighted superposition using GIS. Results show that estimated regional vulnerability score is ranged from 22.7 to 94.5. Central and western areas of Goyang-si which have groundwater tables at shallow depths and are mainly occupied by industrial and residential areas are estimated to be relatively highly vulnerable to groundwater contamination. Based on assessed regional vulnerability, we classified areas into 4 categories. Category 1 areas, which are ranked at the top 25% of vulnerability score, take about 2.8% area in Goyang-si and give a high priority for groundwater contamination management. The results can provide useful information when the groundwater management authority decide which areas should be inspected with a high priority for efficient contamination management.
