The purpose of this study was to investigate differences in the diet with the amount and the qualitative assessment of nutrient intakes by the economic level. Data from the 1998 Korean Health and Nutrition Survey were used. Using the poverty line based on the 1998 Korean minimum cost of living, Subjects (n = 10400) were classified into high class (36.1％), middle class (40.7％) and low class (23.1％). Chi-square-test and Analysis of Variance following Duncan's multiple range test were used to test the difference in nutrient intake pattern among three groups ($\alpha$ = 0.05). The amount of nutrient intake and nutrient intake adequacy were statistically different by the economic level (p<0.01). The ratio of energy intake from carbohydrate is higher than the criteria of WHO recommendation in all economic levels. Especially people in the low class depended much on the carbohydrate for the energy intake. The ratio of energy from the protein and fat are lower in the middle and low class than that of the high class. The Intake level of calcium and vitamin B$_2$ were lower than those of the Recommended Dietary intake level, regardless of economic status. It also showed differences in major food sources of nutrients by the economic level Consequently, it seems that the nutrition policy and program should be prepared according to their economic status. Also, there should more detailed studies to find out the nutrient intake pattern, their determinant, and health consequences.

The study deals with the empirical research on the condition of nutrient intake of low income class which be represented by urban slum and rural area, with the analysis of the factors which might influence on the prevalent condition of nutrient- intake. The method of the research was based on the spot-survey with questionaires. The result is that the levels of nutrient-intake are below the standard requirement level of nutrients in both of urban slum and rural area. The level of nutrient intake in urban slum lies in approximately 50% of the standard requirement level and 80% of the standard requirement level in rural area. The extent of malnutrition was explained in terms of the amount of calorie, protein, calcium and iron. More than half of the population in the community are below the standard requirement level of the nutrient- intake. The problem of malnutrition was serious in urban slum than in rural areas, which made a good contrast with the result of Peru study. Deficiency in calcium was most serious. The factor analysis of the prevalent condition of malnutrition in low class suggests that 1) The function of local market in supplying food is not so effective in the sense that the quality of the foods purchased id the local market is poor. 2) Low level of knowledge, the consequent ignorance and the indifference to the nutrition and the low income led to malnutrition. The level of income and the education were significantly correlated to the nutrient-intake.

This study was conducted using a self boarding questionnaire survey to investigate body image perception, dietary habits and nutrient intakes according to interest level in health of female university students in Masan area (n=302). The subjects were divided into 2 groups according to interest level in health ('High' group, n=101, 'Low' group, n=201). Body image according to BMI was significantly different regardless of interest level in health (p<0.001). The answer percentage indicated that the purpose of weight control is health, regular use of the scale, and regular exercise were significantly higher in the high group (p<0.05). Nutrient knowledge score (p<0.01) and food frequency score (p<0.001) were significantly higher in the high group (p<0.01). There were no significant differences in nutrient intake, but intake, NAR and INQ of vitamin C were significantly higher in the high group (p<0.001). Nutrition knowledge score (p<0.01), food intake frequency score (p<0.01), and INQ and NAR of vitamin C (p<0.01) were positively correlated with the interest level in health. These results will be useful as a basis for the development of effective nutrition education programs in order to increase interest level in health and apply well in real life what have learned through the correct nutrition knowledge.

Through a survey on dietary intake of children and adolescents with brain lesions, the present study aimed to analyze the current status of nutrient intake and examine the effect of high-protein nutrient drink on their nutritional and muscle statuses. The study participants were 90 juvenile participants aged 8-19 years, with brain lesions. The participants were provided with a protein nutrient drink for 12 weeks and a questionnaire survey on dietary intake was performed to analyze the level of nutrient intake before and after ingestion. The physical measurements were taken to determine the improvements in nutrient and muscle statuses. The results showed that, before the intake of protein nutrient drink as a supplement, the participants exhibited lower height, weight, and body mass index than those of the standard levels of healthy individuals, and the level of nutrient intake through diet was lower than those of the required and recommended levels of nutrient intake for Koreans. Conversely, after the intake of protein nutrient drink for 12 weeks, the level of nutrient intake and physical statuses such as weight showed significant improvements. In addition, the muscle status had undergone approximately 10% of change during the intervention with no significant difference. Thus, to ensure an adequate level of nutrient supply to children and adolescents with brain lesions, there is an urgent need to develop a guideline of nutrient intake. The findings in this study are expected to serve as the basic data for such guidelines.

This study was conducted to investigate the influence of different nutrient databases in estimating nutrient intake. A nutrient survey with Food Frequency Questionnaire containing 65 food items was conducted with 2,426 subjects over 30 years of age living in Yeonchon-gun, Kyungki province. The nutrient intakes were first estimated by using one (A) nutrient database which was based on the Korean Food Composition Table, 4th edition. With the other (B) nutrient database which was based on the Korean RDA(Recommended Dietary Allowances) 6th edition, it was reestimated and two resu1ts were compared. For most nutrients except carbohydrate, calcium, vitamin C and $eta$-carotene, mean nutrient intake level estimated from database B was significantly higher than that from database A(p<0.05). Mean intake level of most nutrients from two databases were significantly correlated by Pearson's correlation coefficients(p<0.001). Results from the ranking of nutrient intake levels of the subjects by two databases were highly correlated ( P >0.9, p<0.001). Weighted kappa values representing measures of agreement ranged from 0.55 databases ranged from 45% for vitamin C to 96% for carbohydrate. This result implies that different nutrient database may produce substantial differences in estimating the absolute nutrient intake but may not be crucial in ranking or classifying individuals with regard to specific nutrient intake.

This study was carried out to investigate the level of nutritional knowledge dietary behavior and nutrient intakes of rural housewives and to analyze the relationship among each other. The data for this study collected by the interview with questionnaire in 1990 from the 303 rural housewives of 13 districts and 3 cities in Chunbuk province sampled by random sampling method. Statistics used in analysis were frequency, proportion, X2-test and statistical significance was tested at 0.05 level. The main results of the study were summairzed as follows : 1) Nutritional knowledge score of rural housewives was higher, in young age group than in old group and in high income group than in low income. 2) There were not the significant difference between the dietary behavior of the rural housewives and their nutritional knowledge score. 3) As the nutritional knowledge score of the subjects was higher nutrient intakes level of calcium and iron were higher, however, there were not the significant difference between the nutritional knowledge score and nutrient intakes levels of energy, protein and fat respectively. 4) As the level of meal management were high, only protein intake among various nutrients was increased. There were not the significant difference between the nutrient intakes and their food habits.

We study on the dynamic interaction with a simulated physical-biological coupled model response to nutrient reduction scenario in Jinhae Bay. According to the low relative errors, high regression coefficients of COD and DIN, and realistic distribution in comparison to the observation, our coupled model could be applicable for assessing the marine ecosystem response to nutrient input reduction in Jinhae Bay. Due to the new construction and expansion of sewage treatment plant from our government, we reduce 50% nutrient inputs near Masan Bay and sewage treatment plant. COD achieves Level II in Korea standard of the water quality from the middle of the Masan Bay to all around Jinhae Bay except the inner Masan Bay remaining at Level III. When our experiment reduces 50% nutrient inputs near Masan Bay and Dukdong sewage treatment plant simultaneously, COD decreases to about 0.1-1.2 mg/L $(128^{\circ}30'{\sim}128^{\circ}40'\;E,\;35^{\circ}05'{\sim}35^{\circ}11'\;N)$. The COD from the middle of the Masan Bay to Jinhae Bay achieves Level II.

In order to identify valuable factors for improving dietary quality of Korean rural elderly, the consumption frequency of food groups, dietary habits and health behaviors related to nutrient intakes of the elderly over 85 of Sunchang County were studied. The 171 subjects (61 males and 110 females) were chosen from Sunchang Province by stratified sampling. Among food groups, the consumption frequency of meat and fish groups influenced significantly on their nutrient intakes than the other groups. The subjects consuming more than 4 times per week of meat or fish had significantly higher nutrient intakes level than the other groups. The group consuming milk and milk products everday was higher in vitamin $B_2$ intake level than the other groups. Among dietary habits, the groups with good appetite and regular mealtime compared with the groups with low appetite and irregular mealtime had significantly higher nutrient intake levels. The family type was the determining factor of nutrient intakes. The subjects living with family members consumed higher nutrient intakes than the subjects living alone. The smoking and the alcohol consumption themselves did not affect nutrient intakes, but the subjects having alcohol consumption frequently more than once a day had lower nutrient intakes than the others. The group with dentures did not differ significantly from the without denture group in nutrient intakes; however, those who had chewing problems showed the lower nutrient intakes compared to those who did not have chewing problems. The subjects with more than two kinds of clinical symptoms had lower nutrient intakes than the subjects with less than two kinds of clinical symptoms. These results indicate that the identifying factors for desirable nutrient intakes of rural elderly were characterized as appropriate consumption frequencies of meat and fish, good appetite, living with family, regular mealtime, chewing without difficulty, and low incidence of chronic disease.

Possible correlations between nutrient intake add health status-as assessed by anthropometric measurements, physical performance and biochemical measurements-were investigated, using 514 healthy young men aged 20 years old who had no apparent health problems. The intakes of nutrients were estimated using a three-day dietary recall method. Height and body weight were measured, and body mass index (BMI) was calculated. Physical performance was tested using sit-ups, push-ups, a loom sprint and a 1,500m run. When compared with the Korean recommended dietary allowances (Korean RDA), the subjects nutrient intakes were adequate except for calcium. The intake of calcium was 516.66$\pm$293.43mg/day, which is 73.80 % of the Korean RDA. The subjects averaged 174.51$\pm$7.07cm in height, 68.17$\pm$9.25 kg in body weight and 22.23$\pm$2.16 in BMI. The associations between nutrient intakes and anthropometric measurements, and between nutrient intakes and physical performance, were weak. The intake of vegetable fat was positively correlated to body weight, whereas the intake of carbohydrate was negatively correlated to BMI. The intake of carbohydrate was positively correlated to the level of performance in the loom sprint, and the intake of vegetable Int was positively correlated to the level of performance of sit-ups. No correlation was found between nutrient intakes and the following biochemical measurements of the blood: the levels of glucose, total protein, total cholesterol, triglyceride, hemoglobin and hematocrit. These results suggest that anthropometric measurements and level of physical performance can be associated with energy nutrient intakes, even in moderately active, well-nourished, young men. No correlation was found between nutrient intake and biochemical measurements, probably because all subjects had a reasonably well-balanced diet.

순환식 펄라이트 재배에서 오이의 양액흡수는 일사량 변화와 관계없이 단위일사량당 흡수량이 80~100 mg.MJ$^{-1}$까지 증가 후 일정하게 유지되어 양액흡수 지표는 전체 양액흡수량보다 단위일사량당 양액흡수량이 더 적합하였다. NO￣$_3$-N의 흡수량은 초기에 3 mg.MJ$^{-1}$에서 후기 16 mg.MJ$^{-1}$로 상승하였고 Ca는 초기에 3mg.MJ$^{-1}$에서 후기에 14 mg.MJ$^{-11}$ 로, Mg는 초기에 1 mg.MJ$^{-1}$에서 후기에 5 mg.MJ$^{-1}$로 증가되었으나, 정식 후 62일 이후의 증가세로 둔화되었다. K는 초기에 5.0 mg.MJ$^{-1}$에서 후기 18 mg.MJ$^{-1}$로 증가되었으나 지속적인 증가를 보여주지 못하였는데 이것은 오이의 하엽 제거로 인한 결과로 생각되어진다. 그러나 P는 초기에 0.5 mg.MJ$^{-1}$에서 후기의 3.2mg.MJ$^{-1}$로 지속적으로 증가되었다. S는 초기에 0.5 mg.MJ$^{-1}$에서 증가에 6.5 mg.MJ$^{-1}$까지 증가되다가 후기에 2.7 mg.MJ$^{-1}$로 감소되었다. 오이의 각각의 무기이온 흡수량과 가장 상관이 높았던 요소는 정식일수와 엽면적이었으나 이 두 요소와 단위일사량당 양액흡수량과는 $r^2$=0.92, 0.97로 높은 상관을 보였다. 단위일사량당 양액흡수량을 이용한 각각의 무기이온 흡수량 회귀식은 $r^2$=0.9 이상으로 높은 상관관계를 보여 실용적 이용이 가능할 것으로 보였다.
