Objectives : The purpose of this study was investigation of quality and quantity of nutritional intake related oral health status among Korean elders. Methods : The nutrient intake and the dietary quality was evaluated on the basis of the Dietary Reference Intakes For Koreans(KDRIs). Chi-square test for Complex Samples was used to determine the relationship between oral health and inadequate nutrient intake in Korean elders. The complex samples general linear model was used to test difference of average value difference of nutrient intake percentage compared to dietary reference intake(DRI), energy intake rate from three major nutrients, average mean adequacy ratio(MAR) and index of nutritional quality(INQ) related oral health status. Age, sex and total energy intake was compensated for this analysis. PASW 18 was used for statistical analysis. Results : We could found the difference of the nutrient intake and the dietary quality related oral health status among Korean elders. Especially, Nutrient intake percentage and component ratio of protein among energy intake rate from three major nutrient was lower as oral health status became worse. The percentage of subjects with nutritional intakes under showed highest level in worst oral health status. As oral health status became worse, average mean adequacy ratio(MAR) was lower and the number of nutrient of which index of nutritional quality(INQ) was under 1 was more. Conclusions : From the result above, this study clearly shows the level of oral health affecting the inequalities of eating and the food for the people. And the various propose of oral health policies is needed for vulnerable groups who needs solution to solve the problem of inequality of food distribution where intensive distribution of nutrition problem occurred. Sufficient, safe, and a variety of healthy food intake is a fundamental right of our people. And also, to apply this policy in reality, institutional arrangements and organizations, and specific performing system will be needed.
This study was conducted to assess nutritional status of the elderly from low-income urban area and to investigate environmental and health risk factors that may influence to nutrient intakes. One hindered eighty three(males 53, females 130) healthy homestaying subjects aged over 65 years in Seoul were assessed with anthropometric measurements and dietary intake in August, 1994. HT and BW for females were decreased with aging. The proportion of hypertension was 36% with indite of $SBP{\;}(SBP{\;}{\gg}{\;}160mmHg)$ and 52% with indice of DBP $(DBP{\;}\gg{\;}97mmHg)$. Distribution of BMI, OR and PIBW indicated that BMI was more sensitive for identifying underweight whereas PIBW was more sensitive for identifying overweight. for group aged over 75, males had significantly lower intake of energy, protein, fat, calcium, iron, vitamin A and $\beta$ carotene compared to the group aged 67~74, while females had lower intake of calcium and vitamin A. Elderly group with smoking, less familly size and living alone had lower nutrient intakes. Blood pressure in the elderly subjects did not influence to nutrient intakes, except elderly with normal blood pressure were taking increased amount of thiamin and niacin.
The temperature effect at $20^{\circ}$ and $10^{\circ}$ on the nutrient removal efficiency was evaluated in the combined biological nutrient removal system (CBNR) with anaerobic-intermittent aerobic-oxic reactors. The test was conducted under the conditions of various ratios of intermittent aeration time and distribution of influent raw water to CBNR. The removal efficiencies of organics, nitrogen and phosphorus were a little bit better at $20^{\circ}$ than at $10^{\circ}$. However the large difference of temperature effect on the nutrient removal efficiency between $20^{\circ}$ and $10^{\circ}$ was not appeared because of highly sustained MLSS concentrations in the reactors and controlled intermittent aeration time. In the removal of phosphorus, Mode III (50/70 min in aeration on/off time, 3 times of intermittent aeration) showed more effective compared with short aeration time of Mode IV. In case of N, P removal, the denitrification rate was lower in Mode A with splitted inflow into anaerobic and intermittent aeration basins than in Mode B with sole inflow into anaerobic basin.
To evaluate the oceanographic conditions for the artificial upwelling we measured vertical stratification coefficients, current speed distribution and grain size distribution of bottom sediment in the vicinity of Gukdo and Somaemuldo near Geojedo. There were a strong stratification between surface and bottom layers in summer, the stratification was weak from autumn to winter, and the water was well mixed during winter. In summer nutrient concentration of the bottom layer was 4 times higher than that of the surface layer. Underwater currents were strong in the bottom layer. We conclude that the oceanographic conditions in the area will meet the basic requirement for the construction of artificial upwelling.
This study was an attempt to investigate various factions, such as the calorie, nutrient intake, physical activity, blood lipids, obesity prevalence and body fat distribution on NIDDM male diabetics. General characteristics, physical activity and exercise levels of subjects were invesigated by interviewing, daily calorie and nutrient intake were measured by convenient method. The following anthropometric measurements were made on all participats : weight, height. Also waist and hip circumference were measured on 174 male diabetics to get waist-to-hip circumference ratio as index of the body fat distribution. For measurement of plasma lipids, 12-hour fasting blood samples were drawn The results of this study were summarized as follows : 1. At the onset of diabetes, the major self-diagnosed symptoms were polydipsia, fatigue, and body weight redution 2. The average of daily energy intake of male diabetics was 2106 Kcal which is 96% of the RDA Percentage of energy is that carbohydrate:protein : pat=70:14:16. 3. Among the NIDDM male subjects, 59% was exercise regularly. 4. Obese subjects above in the ideal body weight of 120% are presently 17%, but 39% of subjects were reported to be obese in the past. The mean BMI of the male NIDDM diabetics is 23.3${\pm}$2.6 and the past mean BMI was 25.2${\pm}$2.7 The mean WHR was 0.93${\pm}$0.10. 5. When diabetics were divided into obese and nonobese group according to RBW, energy intake, blood pressure, blood glucose and total cholesterol were not significantly different between the two groups, but LDL and VLDL-cholesterol were significantly higher in the obese group. 6. RBW did not correlate with cholesterol and triglyceride, but WHR correlated significantly with cholesterol and triglyceride. In conclusion, these results from a present study support previous findings indicating that not only the degree of obesity but also the localization of fat is a risk factor for diabetes.
The purpose of this study was to investigate the food habits, nutrient intake, and disease distribution in the elderly (aged over 65 years). The correlation of diseases with anthropometric measurements and nutrients was investigated. The correlation of blood parameters with anthropometric measurements and nutrient intake was also studied. The results are as follow: 1) Most elderly men (68.6%) and women (81.6%) had more than three diseases. The food habits of the elderly women were worse than those of the men. Their intake of protein, calcium, iron, vitamin A, and vitamin $B_2$ were lower than the RDA for those particular nutrients.2) The incidence of gastritis (51.2%) , fatty liver (46.4%) , and hypertension (45.2%) were the highest among elderly men and women. 3) Anemia was negatively correlated with body weight. Hypercholesterolemia was positively correlated with body fat and negatively correlated with intake of calcium, vitamin A, and vitamin $B_2$ . Hypertension was negatively correlated with alcohol consumption. 4) Blood total cholesterol concentration was positively correlated with percent ideal body weight (% IBW) . Blood hemoglobin level was positively correlated with Body Mass Index (BMI) . Systolic and diastolic blood pressure were positively correlated with % IBW and BMI. Blood cholesterol concentration was negatively correlated with the intake of iron, vitamin A, vitamin $B_2$, and cholesterol, and positively correlated with the consumption of alcohol. Blood hemoglobin level was positively correlated with the intake of total calories, carbohydrates, fat, protein, iron, vitamin $B_2$, phosphorus, cholesterol, salt, and alcohol.
This study was conducted to investigate the change in the anthropometric values, biochemical index, nutritional knowledge, food habits and nutrient intakes in obese children after a weight control program. The subjects of the study were 22 obese children with an obesity index over 120%. The children that participated in this study took nutritional education for weight control along with exercise once a week. The weight control program was conducted for 10 weeks. The BMI, WHR (Waist-Hip ratio), body fat (%) significantly decreased at the end of the weight control program. Total cholesterol and LDL cholesterol were also significantly decreased. The nutritional knowledge scores and knowledge score about obesity were slightly improved. Energy intake significantly decreased from 1768 to 1421 kcal. Intake of Ca, Na, K, vitamin A, vitamin $B_6$, vitamin C and folate increased, while intakes of P, Zn, vitamin $B_1$, vitamin $B_2$, vitamin E and niacin decreased. The distribution of energy intake was significantly changed for the better. The percent fat consumed decreased from 26.5 to 19.7%. In addition, the distribution of energy intake in the meals was changed, where the percent calories consumed during lunch significantly increased from 31.4 to 40.1% and the calorie percentage consumed from snacks significantly decreased from 17.6 to 10.7%. In conclusion, the nutritional education in the weight control program, which was conducted for 10 weeks, was effective in improving the anthropometric values, biochemical index and nutrient intake although nutrition knowledge and eating behaviors only changed slightly. Thus, nutritional weight control programs for obese children should be continuously provided under the proper cooperation of a nutritional teacher at elementary schools.

Application of water-saving self-feeders can reduce water consumption of pigs by more than 50% . so the feeding-watering system one of the most important way of the reduction of the slurry. Bioactive deep litter housing can eliminate slurry. Matured urine, faeces and litter can use for the purposes of soil conditioning and fertilizing . Water-saving slurry handling technology can halve manure dilution so it can double the nutrient content of the slurry. By using of straw bale biofilter for reducing emissions of pig houses makes fattening of pigs possible close to populated area. Developed rate control system for slurry application make avoiding over-fertilization possible , can fulfill better the demand of nutrient of plants. By means of computer aided manure utilization system area distribution of soil characteristics can determinate . The system is suitable for planning the utilization of manure and slurry in environment -friendly way.
During the 1st Korea-Russia Arctic Expedition from 3 to 26 August, 2000 phytoplankton biomass and nutrient concentration were measured in the Barents and Kara Seas. Total of 57 surface samples were collected f3r the phytoplankton related measurements. Chlorophyll a (chi a) concentraitons were measured to investigate the relations between physico-chemical factors and phytoplankton biomass distribution. Chl a values ranged from 0.14 to $2.34mg\;m^{-3}$ (mean of $0.65{\pm}0.42mg\;m^{-3}$) over the surface stations. The elevated values of the chi a concentrations $(1.49{\sim}2.34mg\;m^{-3})$ were found in the southeastern Barents Sea near the Pechora River. Nanoplanktonic $(<20{\mu}m)$ phytoflagellates were the important contributors for the increase of the chi a. The nano-sized phytoflagellates accounted for more than 80% of the total chi a biomass in the study area. Mean chi a concentration in the Barents Sea $(0.72{\pm}0.57 mg\;m^{-3})$ was higher than in the Kan Sea $(0.52{\pm}0.45mg\;m^{-3})$, but there was no big difference between two areas. Surface temperatures and salinities ranged from 4.1 to $11.7^{\circ}C$ (mean of $8.8{\pm}1.9^{\circ}C$) and from 23.8 to 32.5psu (mean of $30.3{\pm}1.9^{\circ}C$ psu), respectively. The physical factors were not highly correlated with phytoplankton distribution. It is speculated that the insignificant correlation between phytoplankton biomass and physical factor was due to the same current which introduced similar water mass with higher water temperature and lower salinity into the study area. The mean values of major nutrients such as ammonia, nitrite, nitrate, phosphate, and silicate were $0.42{\pm}0.31{\mu}M,\;0.10{\pm}0.03{\mu}M,\;1.44{\pm}1.03{\mu}M,\;0.35{\pm}0.12{\mu}M,\;10.99{\pm}3.45{\pm}M$, respectively. The relations between phytoplankton biomass and nutrient concentration were not close, indicating that the surface nutrient concentrations during the study seem to be controlled by other physical factors such as input of fresh water (i.e. dilution effects).
This study is to investigate consequent nutrient intake status, influence of body mass index(BMI), and fat distribution on the silk amino peptide(SAP) and dietary fiber supplementation. During 2 months of this research (January to March, 2002), 45 women aged 20yr – 30yr (average age 24.6yr) were selected as subjects. Nutrient intake was investigated by questionnaire, 24-hr recall method. Antropometric assessments of the subjects were investigated by SBIA method(Segmental bioimpedance assay, In body 3.0). The results are as follows: mean body weight 57.7kg, mean body height 161.9cm mean BMI 22.0, and mean food habit score was 8.47. Defecation frequency was increased by dietary fiber supplementation. Frequency of pain during defecation was significantly decreased by dietary fiber supplementation (p<0.01). Feeling of residual feces was significantly improved by dietary fiber supplementation(p<0.001). Status of energy and carbohydrate intakes significantly decreased after dietary fiber supplementation(P<0.05). Body fat and WHR(waist hip ratio) significantly decreased after dietary fiber supplementation(P<0.001), and percent body fat was decreased by dietary fiber supplementation, significantly(P<0.05). Above results of this study show that dietary fiber-added routine diet improves defecation condition, and lessens body fat, percent body fat without losing body muscle. Especially, declination of abdominal fat and WHR were notable. That meant decreased risk factor.
