Purpose: The atherogenic index of plasma (AIP) is gaining recognition as a superior predictor of coronary artery disease. This study examined the relationship between the AIP and the intake of various food groups in Korean adults, using the baseline data from the Korean Genome and Epidemiology Study-The Health Examinees (KoGES-HEXA) study. Methods: This study included 133,381 adults (46,288 men, 87,093 women) who completed the nutrition survey and biochemical tests of the KoGES-HEXA study. The AIP was calculated as the log (triglycerides/high-density lipoprotein-cholesterol) and was divided into quintiles according to sex for further analysis. Data on food group intake were obtained using the semi-quantitative food frequency questionnaire, and daily food group intake (g/d) was evaluated for each individual. The association between the food group intake and the AIP was examined using the linear regression analysis after adjusting for the confounding variables. Results: In this study population, there was a positive correlation between energy intake and the AIP in men whereas an inverse assocation was shown in women (p < 0.001). In women, a rise in the AIP significantly correlated with an increased percentage of energy intake derived from carbohydrates but decreased percentages of energy from protein and fat (p < 0.001). In men and women, the consumption of grains and kimchi/pickles increased as the AIP rose, while the intake of legumes, nuts, meat and its products, eggs, fish, and milk and dairy products decreased. Among men, individuals in the highest AIP group showed higher intake of wheat products than those in the lowest group of the AIP. In women, the AIP was inversely correlated with potatoes and beverages consumption. Conclusion: This study highlights the importance of a balanced diet, including various protein sources, milk and dairy products, legumes, and nuts, for preventing cardiovascular diseases. Further research into sex-specific dietary patterns is essential for tailoring appropriate dietary recommendations.

Health is the most important factor in the Quality of life. Without appropriate treatment, dental caries could have serious effects on self-esteem, nutrition, and health of a person throughout his/her life. The purpose of this study was to investigate ways to develop a consumer information program that could help improve teens' oral health. To develop an effective information program, we surveyed 1) how teens feel about oral health information in the market, 2) how judiciously they use their information, and 3) how they actually apply the information to practice. On the other hand, we investigated relationships between dietary patterns and dental caries among middle school students. The results indicate a serious lack of oral health information for middle school students. Moreover, we found that the intake of vegetables, fruits and legumes prevents dental caries. Using these results, we developed a system for organizing and conveying the oral health information for teens.

Due to recent scientific innovations in mulberry cultivation, leaf yield has been increased manifold. However, with successive leaf harvest, a quantum drop in leaf yield and quality has been noted. This inturn has affected the silkworm rearing and farmers suffered by the frequent crop failures. This is mainly due to nutrient deficiencies in mulberry leaf. Moreover, no complete information is available about hunger signs of nutritional disorders, analytical diagnosis and critical levels of nutrients required. The present paper, thus, may serve as an important nutrient guide for identification of hunger signs, leaf nutrients status under deficiency and critical levels of the elements namely N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn requirements for higher leaf yield and quality. The leaf nutrient status provided may help chemist for correcting the soil status. Besides, an integration of mulberry intercropping with legumes and applications of neem and castor oil cakes, VA-mycorrhizal inoculation, biofertilizer and vermicompost are suggested as integrated nutrient management for sustainable sericulture industry. Based on the information described in this paper, a model needs to be framed for maintaining continuous supply of nutrients to obtain desired quantity and quality of mulberry leaf for successful silkworm cocoon crop and increasing overall silk productivity.

To study management practices suitable for the least production loss of temperate pasture under summer stress, two different cutting dates (late June and mid July) under summer stress and five different nitrogen treatment application levels (0, 100. 200, 300 and 400 kg/ha) were tried during the trial period between Oct. of 1986 and Oct. of 1989. The late June cutting showed a statistically significant increase of dry matter yield of pasture in comparison with the mid-July cutting(P<0.05). Nitrogen application also gave significant increase in dry matter yield. Botanical composition at the 4th cuttings in 1988 and 1989 was dominated by weeds to the level of 50%, Application ofnitrogen at 200 kgs per ha was found to be the best with production of grasses at 70%, legumes at 10 % and weeds at 20% in botanical composition comparison of pastures at the 4th cutting time the last year, showing a great decrease of weeds. K contents of pasture in June cuttings showed to be more than them in July cutting, and N and Na contents increased with increases of the nitrogen application level. It was concluded that treatment with June cutting and nitrogen application of 200 kg per ha was a way to keep temperate pasture from summer stress in the Cheju area.

This field experiment was conducted to determine the effect of grazing and cutting management on the forage production and botanical composition at different legumes sown swards of the experimental field of Livestock Experiment Station. in Suweon, from Aug. 1985 to Oct. 1988. The results obtained are as follows: 1. Dry matter yield of cutting management (1213.0 kg/lOa) was higher by 19% than that of grazing management (1016.8 kg/lOa). Yield of pasture mixtures including alfalfa both cutting and grazing were higher than those including ladino clover and red clover. Yield under grazing was inferior to cutting in the first year but superior in the second year. 2. Seasonal dry matter production under grazing showed 5 1% in spring, 33% in summer and 16% in autumn, but under cutting showed 46% in spring, 42% in summer and 12% in autumn. 3. Daily dry matter production per 10a under grazing is decreased 5.9 kg in spring, 5.5 kg in summer and 3.7 kg in autumn. But under cutting is decreased 8.7 kg in summer, 6.6 kg in spring and 3.4 kg in autumn. 4. Botanical compositions of mixtures swards involving ladino clover and red clover were not influenced by method of defoliation. But mixtures swards including alfalfa were highly influenced by method of defoliation. Alfalfa ratio at the time of final utilization under grazing was about 30%, but under cutting was about 70-80%.

The strip intercropping system has used due to many advantages. Many researches supported these crop systems are usually equal to or better than monoculture crop systems in both total production and profit. There was no research to examine the important ecological factors in the competition between crops. A strip intercropping system composed of adjacent narrow strips of corn, soybean, and oat/legumes has been investigated in Iowa, USA. This study conducted to investigate why and how the differences in soybean yield are produced and affected by light, one of the microclimate, of the strip intercropping system. In height, the two rows of soybean closest to corn were taller than the two rows near the then-empty oat strip. The height of each crop decreased as the amount of light received increased. Weight of plant parts was lowest in row 1, nearest corn, and highest in row 4, next to the vacant oat strip. Daily photon flux density(PFD) increased with increasing distance from corn, with the highest value occurring on the edge next to the empty oat strip. Analyses of the relationship between light and biomass of soybean showed that all biomass measurements had a positive relationship to total PFD per day except height.

This trial was carried out to investigate the effect of oversowing on the fodder value and the life form of standing crop in the low productive grassland with a western exposure at the Korean Native Cattle Improvement Center in Seosan. Chungnam Province. The results obtained are summarized as follows: 1. The inferior plant community of low productive grassland was improved to the most desirable pasture association by oversowing after herbicide application. At the experimental area most of the native grasses were not suitable for the pasture plant due to less fodder value(0-2). 2. The fodder value of standing crop in the improved grassland with 6.04(grasses: 4.72, legumes: 1.07 and herbs: 0.25) was much more increased by 108% than that of low productive grassland. 3. The life forms of plant community in the low productive grassland were composed of Hemicryptophytes of 36.29'0, Therophytes of 30.47~, Chamaephytes of 17.0% and Geophytes of 16.4%). But by oversowing after herbicide application their life forms of Hemicryptophytes increased greatly by 51.4%, on the other hand Therophytes, Chamaephytes and Geophytes were much more decreased by 25.4, 15.6 and 10.470, respectively.

Preferences of 814 elderly living in Incheon for dishes, food materials and cooking methods were investigated. The survey was conducted from Dec. 2000 to Jan. 2001 by questionnaires. Subjects preferred cooked rice with beans, kalkooksoo(hot noodle), gomtang(soup with beef), bibimbap(rice with assorted mixture) to other staple dishes. However, preference for hashed rice or curried rice was very low. More than 50% of the subjects liked soybean paste soup and stew, and the ratio of elderly who liked Chinese cabbage kimchi was 68.7%. There was no significant difference in preference for pan-fried foods according to food materials in them. Subjects liked injolmi(waxy rice cake), shikhye(fermented rice drink) and coffee the most. Most subjects preferred plant foods like vegetables, legumes and seaweeds to animal foods. Preference of elderly for milk and yoghurt was reatively high; however, that for ham, butter and cheese was low. Elderly in Incheon liked roasted beef, beef soup and roasted pork the most. Chicken was preferred when it was boiled in water with garlic, ginseng, and so on. Cooked and seasoned vegetables (Namul) were the most preferred type by elderly. Preferences for dishes and food materials were more affected by living places of the subjects than by sex, and the reverse was true in preference for cooking method of food materials.

The purpose of this study was to investigate whether nutrition counseling could lead to a beneficial outcomes in patients with cardiovascular disease(CVD). Fifty CVD patients(23 men and 27 women) participated in a dietary counseling program which was based on serum lipid management. Various markers of disease risk including lifestyles, anthropometric indices, eating behaviors, serum lipids, antioxidants, lipid peroxides were measured before and after the program. The program lasted 3-11 months depending on individuals. Waist/hip ratio decreased after nutrition counseling only in women. Smoking and alcohol drinking status did not change significantly after counseling. Food habit score increased significantly in both men and women(p<0.05), and patients consumed mixed cereal rice, fruits, seaweeds, legumes more frequently and snacks less frequently after nutrition counseling (p<0.05). Although intakes of energy, carbohydrate and vitamin B1 were reduced significantly after nutrition counseling, nutrient densities of calcium and iron of diets have increased significantly after nutrition counseling, and those of other micronutrients were not different Serum total cholesterol decreased significantly in men and LDL cholesterol decreased significantly in women. In women lipid peroxide level decreased and $\alpha$-tocopherol level increased significantly, while there was no significantly change in men. We conclude that well-planned nutrition counseling would reduce risks of cardiovascular disease through improving dietary behavior, lipid profile and antioxidant status.
