The purpose of this study was to investigate the effect of food habits on blood components level(blood glucose, uric acid, hemoglobin, some lipids levels) and health condition in Taejon. The study was conducted with 250 subjects (male 130, female120) who visited in a general hospital from May to June in 1997. Questionaires were used for food habits. The data were analyzed by using $x^2$-test, t-test, ANOVA and multiple range test. Results were summerized s follow : mean of Broca Index were 110.0 $\pm$13.7% in male, 110.6$\pm$16.6% in female. Mean values of systolic blood pressure and diastolic blood pressure were 130.9$\pm$17.6mmHg, 76.2$\pm$12.6mmHg, respectively. The systolic blood pressure was significantly higher in man than woman, Mean serum total cholesterol, LDL-cholesterol, and HDL-cholesterol and triglyceride levels were 202.8$\pm$40.2, 121.1$\pm$35.5, 50.3$\pm$12.9, 157.1$\pm$112.6mg/dl, respectively. Triglyceride level was significantly higher in man than woman. But HDL-cholesterol was significantly lower in man than woman. And also, the value of LPH and AI were higher in man. So Man has more risk of atherogenesis than woman. Mean values of blood sugar, uric acid and hemoglobin was 102.7$\pm$1.36mg/dl and 14.1$\pm$1.56g/dl were higher in man than woman except blood sugar. Food habit of woman were better than it of man. The levels of education and income did not affect to food habit score. The most problem of habits were intake of salty food and lack of exercise. The intake of nutrients were higher as food habit score was higher. Intakes of energy, Ca, vitamin A and vitamin $B^1$ were lower than RDA's of nutrients in bad food habit group. This result did not show that blood components level and health condition were significantly different by food habits. But Broca Index and triglyceride levels were higher in bad food habit group than other groups, but not statistically significant. By this result, it is more needed food habit education to man and young people. The education of food habits will include the real methods of weight control, low intake of salt and exercise to bad food habit group.

This study aimed at investigating correlation of nutrients intake and serum lipids of industrial workers. 226 for adult aged 20yr~59yr (average age 35.9yr) were selected as subjects during 6 months, from June to December, 1997. Nutrients intake was investigated by questionnaire, 24-hour recall method. Antropometric assessments, serum lipids and blood pressure of the subjects were investigated. The results as follows ; In total subjects, calories, calcium, vitamin A, vitamin $B_1$, and vitamin $B_2$ were below Korean RDA(recommended dietary allowances) and protein, iron, vitamin C, niacin and phosphorus were above Korean RDA. Distribution of BMI groups were underweight groups(7.9%), normalweight groups(63.3%) and overweight groups(28.8%). In BMI groups, intakes of calories, carbohydrates, protein, fats, iron, niacin and potassium of overweight groups were higher than those of other groups, significantly(P<0.001). Intakes of calcium of underweight groups were lower than those of other groups, significantly(P<0.05). BMI increased with age. Total cholesterol, triglyceride, apo(b) and atherogenic index of overweight groups were higher than those of other groups, significantly(P<0.001). Calories, carbohydrates, protein, fats, iron, vitamin $B_1$, vitamin $B_2$, niacin, natrium and potassium were positively correlated with BMI, significantly(P<0.001). Calcium and vitamin C were positively correlated with BMI, significantly(P<0.01). vitamin A and phosphorus were positively correlated with BMI, significantly(P<0.05). Total lipid, total-chol., triglyceride, apo(b) and atherogenic index were positively correlated with BMI, significantly(P<0.001). HDL-chol. were negatively correlated with BMI, significantly(P<0.001). Above results, the more BMI and age increased, the worse patterns of serum lipid, so that increased atherogenic index that increased risk of atherosclerosis and degenerative chronic disease connected with serum lipid. After classified by BMI, age and lipid pattern, it will be managed individually for health management of industrial workers. Development and application of efficient program will be urgent for harmonious nutrition counseling and guidance.

The fertility of stream water in major streams of the Lake Shihwa Watershed was compared using water analyses and algal growth potential test (AGPT) in typical drought seasons from December 2001 to April 2002, The water quality varied considerably depending on streams. These streams were very rich in inorganic nutrients that the nutrient levels and characteristics of each stream could be easily determined. Through AGPT, 63.6% of growth was observed in the average values of each stream, with non-growth accounting for 36.4%. AGPT results showed that 40.9% of the 22 stations were in hypertrophic condition and 54.5% in eutrophic condition. AGPT values were significantly correlated with TIN, $NH_4$, and SRP (p <0.001); compared to other nutrients, however, they were more related to SRP and $NH_4$. Moreover, the values increased with high concentration of N and P and low N/P ratios. Nonetheless, the values were more dependent on P concentration than N concentration. This suggests that the effect of P on the water quality of lake situated in downstream may serve as a potential indicator of phytoplankton development. Depending on the drainage pattern of streams, the wastewaters of wastewater treatment plant (WwTP) and untreated wastewater (UTW) were found to have 53.4% and 46.6%, respevtively, of TIN, 51.9% and 48.1% of $NH_4$, 62.9% and 37.1% of $NO_3$, 62.6% and 37.4% of SRP, and 44.1% and 55.9% of SRSi. The AGPT value was 51.1% in WwTP wastewater and 48.9% in UTW wastewater, the concentration of WwTP wastewater was slightly higher. For untreated wastewaters flowing into the constructed wetland and into the lake, TIN accounts for 43.0% and 57.0%, respectively, of nitrogen components, $NH_4$ 44.4% and 55.6%, $NO_3$ 39.6% and 60.4%, SRP 53.5% and 46.5%, and SRSi 52.3% and 47.7%, respectively. The AGPT value was 58.0% in the constructed wetland and 42.0% in Lake Shihwa; the concentration in streams flowing into the wetland was slightly higher. Therefore, Persistent and large development of phytoplankton in Lake Shihwa cannot be prevented unless a measure tophytoplankton control is implemented. This is because the concentration of nutrients in specific streams flowing into the lake is very high, even though the inflow of water is low.

The discovery of the relationship between nutrients and deficiency diseases during the 100 years from the mid-1800s to the mid-1900s was a breakthrough that led to advances in the study of nutrition. The Recommended Dietary Allowances (RDA) were created as a quantitative standard for avoiding diseases caused by nutrient deficiency. In addition, a reductionism paradigm has become generally accepted among nutrition scholars in health and disease, which focused on the properties of individual nutrients, content in foods, cellular levels, and mechanisms of action. The reductionist paradigm worked very well for the prevention and treatment of malnutrition diseases. However, as the incidence of nutrient deficiencies decreased and that of chronic diseases increased, the nutrition goals have been changed to secure safe and adequate nutrient intake and to reduce chronic disease risks. Accordingly, Dietary Reference Intakes (DRIs), a set of nutrient-based reference values, were designed to replace the RDA. The revised Korean DRIs were published for 40 nutrients in 2020. However, there is still room for improvement in the reference intake levels targeted at reducing the risk of chronic disease. The reductionist approach can no longer be practical because chronic diseases are related to the interactions between multi-components in the foods and multi-targets in the body. Therefore, a second innovative leap is needed following the nutrition development breakthrough made over 100 years ago. To this end, the nutrition paradigm must evolve from reductionism to a holism approach. Cutting-edge scientific technologies, such as metabolomics, transcriptomics, microbiomics, and bioinformatics, should also be acceptable in nutrition science based on the knowledge gained from basic nutrition studies.

Dental caries taking place with milk teeth affects eruption of permanent teeth adversely, and thus, it is very important to prevent dental caries from taking place with a child in maintaining his/her physical, mental and emotional health. In this study as conducted to obtain basic data to be required for development of a program for letting preschool children form a habitual life for oral health and right dietary life, a total 172 children aged 5 years and 6 years were selected from children who lived in Hwasung-si, Kyunggi-do and attended preschools (childrens houses) located there with the consent of their guardians. Then, the weight length index (WLI) and blood components of each child were analyzed, and each relation between the weight length index (WLI) and dental caries of milk teeth and between blood components and dental caries of milk teeth was comparatively examined, and thereby, the following results were obtained. When the dmf rate of each group according to the obesity was examined, it was found to be 87.50% in the under-weight group, 71.20% in the normal weight group and 83.87% in the overweight group. And when the dmft rate of each group was examined, it was found to be 48.43% in the under-weight group, 37.10% in the normal weight group and 47.17% in the overweight group. Also, when the dmft index of each group was examined, it was found to be 3.9 in the under-weight group, 3.0 in the normal weight group and 3.8 in the overweight group. That is to say, the under-weight group and the overweight group having an abnormal weight were found to be higher in all of the dmf rate, the dmft rate and the dmft index than the normal weight group. It could be, therefore, known that normal weight should be maintained in order to prevent dental caries of milk teeth. And, it is thought that a right dietary life habit ensuring intake of balanced nutrients should be formed for maintenance of a normal weight. As a result of examining the relation between nutrient components in blood and dental caries of milk teeth, in the case of children with no dental caries, inorganic nutrient components of blood had a tendency to be a little higher, but no statistical significance was observed therein. Meanwhile, it was found that there was a relation between blood type and the dmft index.

One of the most powerful health management practices is the use of antibiotics, but their use is being restricted because of health safety issues. The swine industry has been looking for various alternatives to antibiotics and increasingly considers the use of dietary factors like feed ingredients, feed additives, feed formulation practices, or feeding methods, instead of using antibiotics to improve pig health and performance. Among other alternatives to antibiotics, spray-dried plasma may be a candidate. Spray-dried plasma is a blood product that provides bioavailable nutrients and physiologically active components such as immunoglobulins, glycoproteins, growth factors, peptides, etc. It is an excellent protein source with balanced and highly digestible amino acids. Several beneficial physiological activities depend on components of spray-dried plasma, such as immune competence (antibacterial activity), modulation of microbiota and/or immune system, integrity of intestinal barrier function, etc. These beneficial effects can contribute to improvement of pig performance and health by modulation of microbiota in the digestive tract and/or immune system. Therefore, it is suggested that spray-dried plasma has great potential as an antibiotics alternative.
