The objective of experiment was to investigate the effects of planting density on growth and yield of vegetable soybean, and to clarify the optimum planting density of vegetable soybean in the middle west region of Korea. The field experiment with 4 levels of planting density was carried out at Yesan area in $2005{\sim}2006$. The days from seeding to flowering and the days from seeding to harvesting and lodging were not significantly different among planting distance. The stem length was increased as planting distance was shortened but the number of node, branch, pod per branch, pod per individual, weight of stem and pod, one hundred pod weight and rate of 2+3 seed per pod were decreased as planting density was increased. The size of vegetable soybeans was not significantly different among planting distance, but the harvest index of vegetable soybean was decreased as planting distance was shortened. Yield of vegetable soybean was increased as planting distance was decreased. However, the approriate densities for stem and pod weight per a plant, number of pod per a branch and the vegetable soybean yield of 2+3 seed per pod were different from that density. The optimal planting distance of varieties was $60{\sim}25\;cm$ in Sunheukkong and Ilpumgeomjeongkong and was $60{\sim}35\;cm$ in Galmikong.

Soybean meal was widely used as a protein source in pig feedstuff because it has a good amino acid balance compared with other vegetable sources. However, soybeans contain trypsin inhibitors and other antinutritional factors which can lead to lower the digestibility of amino acid, and consequently reduce the growth performance. Heat treatment of soybeans is helpful shown to decrease the antinutritional factors and elicit an improved growth performance. Additionally, microbial processe using(HP 100, HP 200 and HP 300), and non-protein constituent removal are suggested to improve the growth performance and nutrient digestibility. Inadequate heat treatment of soybeans gives no damage to adult pig, but it has been shown to decrease nutrient digestibility in young pig. So, soy protein concentrate (SPC) and Isolated soy protein(ISP) were more widely used for nursery pigs than growing and finishing pigs, since SPC and ISP have similar characteristics as milk product.

Ninety samples showing mosaic symptoms on soybean (Glycine max) cv. Sukryangputkong were collected from the Cheongsongkun area, Kyungbuk province in Korea. Initially, DAS-ELISA was conducted far detection of Soybean mosaic virus (SMV). Negative samples were chosen at random and mechanically inoculated on soybean cv. Buffalo, which reported not to produce mosaic symptoms when mechanically inoculated with SMV. An isolate of SMV, designated as B-1, from Buffalo showing mosaic and mottle symptoms was used for identification and biological characterization of the causal vim. The purified B-1 isolate had spherical particles of approximately 24nm. It positively reacted with the antiserum against Cowpea mosaic virus (CPMV) but not with Cucumber mosaic virus (CMV) and SMV antisera. CPMV was newly isolated from soybean and had been characterized by host range and by serological and electron microscopic methods. Results of this study suggest that CPMV is the possible cause of mosaic disease in vegetable soybean and that based on sympto-matology, a difference between the typical mosaic and rugose symptoms caused by SMV and CPMV was observed. This is first report of CPMV from soybean in Korea.

In this study, the quality characteristics of texturized vegetable proteins (TVP) produced from defatted soy flour (DSF) were analytically compared with those of texturized vegetable proteins produced with isolated soy protein (ISP) and non-defatted soy flour (SF). The base raw material formulation consisted of 50% soy proteins, 30% gluten, and 20% corn starch. A cooling die-equipped extruder was used with a barrel temperature set at 190℃ and screw rotation speed of 250 rpm. With respect to the hardness of isolate soy proteins, that of soy flour and defatted soy flour was 22.4% and 68.8%, respectively, and gumminess was 17.6% and 44.3%, respectively. Defatting increased chewiness, shear strength, and springiness. Moisture content was higher in soy flour than in defatted soy flour, while there were no significant differences in terms of water absorption and turbidity. The pH was higher with soy flour than with defatted soy flour. Concerning color, the L and b values were higher with soy flour, while the a value was higher with defatted soy flour. These results suggest that defatting soybeans can improve the quality of plant-based proteins. Further research is needed to address the quality differences from those of isolated soy proteins.

This study was conducted to obtain the basic informations for producing high quality seeds of vegetable soybeans. Four vegetable soybean cultivars, 'Okharawase', 'Mikawashima', 'Hwaeomputkong', and 'Seokryangputkong' were planted at four locations, Chulwon(altitude, 192m) and Pyeongchang(altitude, 370m) in highland, and Suwon(altitude, 37m)and Daegu(altitude, 55m) in lowland of Korea with two planting dates, May 15 and June 15. Seed infection rates were attributed by in order of phomopsis seed decay caused by Phomopsis spp., seed mottling caused by soybean mosaic virus (SMV), purple seed stain caused by Cercospora kikuchii. Seed infectron rate was the lowest at Pyeongchang and lower on June 15 than on May 15 planting. Phomopsis seed decay by Phomopsis spp. was lower in highland of Korea, Pyeongchang and Chulwon, than in lowland of Korea, Suwon and Daegu. Seed infection rate was also lower on June 15 planting than on May 15, and in seeds harvested at maturity than at ten days after maturity. Germination rate of seeds harvested in highland, Pyeongchang and Chulwon, after six to seven month storage at 5$\pm$1$^{\circ}C$ was more than 90% and higher than that of the seeds in lowland, Suwon and Daegu. Germination rate was also higher on June 15 than on May 15 planting.

To investigate the food choices and Dietary Preferences of College Women the number of dishes sold and the sales of the midmeal at the Student Cafeteria, Ewha Womans University were recorded for the fiscal year of 1974; and the observations were made on two consecutive days (June 3rd and 4th, 1974)on what a person has chosen which and how many dishes. The relationship between the number of the consecutive days and the number of foods chosen were treated as Chi square analysis. The results of the food choices and dietary preferences of College Women were as follows: 1. Breads and rice cakes, vegetable dishes, milk and milk products, rice dishes, soups, meat, fish, poultry and eggs, Kimchis and one dish meal were chosen highly; and beverages, stews, and soybeans and soybean products were chosen negligibly. 2. One dish meals, vegetable dishes, meat, fish, poultry and eggs, milk and milk products showed the highest sales volume during the year; rice dishes, breads and rice cakes were the second highest in sales amount; fried foods, snacks and Kimchis showed the range of $3{\sim}6%$ of the total sales; and the beverages, stews, soybean and soybean products were the lowest in sales amount. 3. Seasonal differences were noticed on some dishes. Breads add rice cakes, milk and milk products showed the high selections from March to November and the low, during December to February. Stews, Kimchis, beverages were kept low except sudden rise on February. One dish meal and rice dishes showed almost same level during the year but on February the slight increase were noticed; even level were kept on meat group except the increase to $13{\sim}16%$ on July and December. Fried foods were kept on similar level during the year except the increase on June. Snacks and fruits showed low selections on March, April, November and December and higher at summer. Vegetables, soups, soybean and soybean products showed no different fluctuations in selections during the year. 4. Rolls, salads, milk, hamburgers, fried vegetables, rice with mired vegetables(Bi-bim-bab), and Nang-myun were the single dishes chosen most frequently. 5. There is significant relationship at 0.05 level between the consecutive days and the number of foods chosen. It is concluded that about 50% of the population has taken one item of dishes. The popular combinations were one dish meal and soup or Kimchi; noodles and salads or fried vegetables. It is suggested to set up choice menus with the daily variations, cyclical variations and with the invariable ones; and to recommend one dish meal, breads, partial meals for school lunch; and to study to improve one dish meal, vegetable dishes and fried foods, which are new and inexpensive products. It is also suggested that the feeding of the college students should have to lead the people to the goal that the nutrition education is desired.

Rapeseed(Brassica napus L.) is an important oil crop as a vegetable oil, concentrated feed and industrial materials. The name "canola" was registered in 1979 by the Western Canadian Oilseed Crushers Association to describe "double-low" varieties. Double low indicates that the processed oil contains less than 2% erucic-acid and the meal less than 3mg/g of glucosinolates. Today annual worldwide production of rapeseed is approximately 35 million tons on 24 million hectares. China accounts for 33% of the world production and the European Economic Community for nearly 32%. Canola ranks 3rd in production among the world's oilseed crops following soybeans, sunflowers, peanuts and cottonseed. The recent advances in genomics and in gene function studies has allowed us to understand the detailed genetic basis of many complex traits, such as flowering time, height, and disease resistance. The manipulation of seed oil content via transgene insertion has been one of the earliest successful applications of modern biotechnology in agriculture. For example, the first transgenic crop with a modified seed composition to be approved for unrestricted commercial cultivation in the US was a lauric oil, rape-seed, grown in 1995. There were also some significant early successes, mostly notably the achievement of 40% to 60% lauric acid content in rapeseed oil, which normally accumulates little or no lauric acid. The name "$\textrm{Laurical}^{TM}$" was registered in 1995 by Calgene Inc. Nevertheless, attempts to achieve high levels of other novel fatty acids in seed oils have met with much less success and there have been several reports that the presence of novel fatty acids in transgenic plants can sometimes lead to the induction of catabolic pathways which break down the novel fatty acid, i.e. the plant recognizes the "strange" fatty acid and, far from tolerating it, may even actively eliminate it from the seed oil. It is likely that, in the future, transgenic oil crops and newly domesticated oil crops will both be developed in order to provide the increased amount and diversity of oils which will be required for both edible and industrial use. It is important that we recognize that both approaches have both positive and negative points. It will be a combination of these two strategies that is most likely to supply the increasing demands for plant oils in the 21st century and beyond.ant oils in the 21st century and beyond.

This study was conducted to detennine the dietary and lifestyle factors related to bone the mineral density (BMD) of postmenopausal women with decreased BMD. The subjects (N =163) were recruited from women who visited a orthopedic clinic for BMD check up. A trained dietition interviewed subjects individually to obtain data about dietary behavior, consumption frequency of foods known as main dietary source of calcium and potassium, and clinical symptoms. The risk factors were identified by correlation and multiple regression analysis of variables. The mean age of the subjects was 66.8 yews. Most of them showed low levels of education and monthly income. The mean age of menarche and menopause were 17.2 and 48 year, respectively. The mean menopause duration was 18.7 year. Most of the consumption of calcium was centered to vegetable foods. Education level were positively correlated (r =0.272, P < 0.05) with BMD whereas age, menarch age, menopause duration, number of children were negatively correlated (r=-0.355, r=-0.240, r=-0.283, r=-0.193, respectively, p < 0.05) with BMD. The consumption of soybean, radish were positively correlated (r=0.187, r=0.158, respectively, p < 0.05) with BMD. Potassium intake with rice showed significantly negative correlation with BMD (r =-0.189, P < 0.05), but calcium intake with brown seaweeds, bean sprouts were positively correlated (r =0.247, r =0.254 respectively, p < 0.05) with BMD. Protein intake with roasted pork was also positively correlated (r =0.216, P < 0.05) with BMD. Multiple regression analysis showed that the most prominent negative predictor influencing the BMD was age. Minor negative factors influencing the BMI were age of menarche, potassium intake from rice. But the significantly positively factors influencing the BMD were consumption of radish and soybean intake, education, and protein intake with roasted pork. In conclusion brown seaweeds, radish or soybeans can be promoted as cheap foods replacing milk and milk products for menopausal women with low income.

Kojedo is the second largest island in Korea and a total population of 115,500 is living on the island of 394.69 sq. km. Under the direction of three nutrition professors, nutrition surveys in two villages in Kojedo, namely Siljun Ri in Hachung Myon and Soowol Ri in Shinhyun Myon, were carried by 30 college senior students majoring in nutrition from August to 20 August 1977. From a total of 176 households of the two villages, 67 households were randomly selected and 390 family members of the households were subjcets of the nutrition surveys. The precise weighing method was used in evaluating the kinds of foods and nutrient intakes of the subjects for three consecutive days. Thirty-seven pre-school children aged between 3 to 6 years and 27 fertile women were examined for biochemical findings and physical status. The main purposes of the surveys are to provide baseline data on nutrition in Kojedo Island for the Kojedo Community Development Project and to compare the nutritional status of the villages of Siljun Ri and Soowol Ri. Siljun Ri is located in the pilot project area of the Koiedo Community Health Project sponsored since December 1970 by the Christian Medical Commission of the World Council of Churches. While Soowol Ri is a control village for comparison. The results obtained are summarized as follows: Food Intake The average food intake per person per day in Siljun Ri, 1064 grams (91.7% in vegetable foods and 7.6% in animal foods) was 90 grams more than that of Soowol Ri, 974 grams (92.8% in vegetable foods and 5.9% in animal foods). However, the food intake per pre-school child in Siljun Ri, 485 grams (92.6% from vegetable foods and 6.4% from animal foods) was 21 grams lower than that of the Soowol Ri, 506 grams (88.5% from vegetable foods and 6.5% from animal foods). The average intake of beans was 16 grams(1.5% out of the total food intake) in Siljun Ri and 21 grams(2.2% of the total food intake)in Soowol Ri. The villagers should be guided for more consumption of soybeans to improve the quality of protein intake from vegetable foods. Nutrient Intake The adult intake in Siljun Ri and Soowol Ri were 2,529 kcal and 2,511 kcal respectively. The average energy intake of pre-school childen in Siljun Ri was 948 kcal and that for adult and 1,500 kcal for childen aged between 4 to 6 years-given by the Korea FAO Association, the diets in both villages were not adequate. Average daily protein intake of the subjected adult in Siljun Ri was 78.4 grams and that of Soowol Ri was 76.2 grams, while pre-school children took 30.7 grams in the former village and 31.7 grams in the latter village per child per day. The protein intake in both villages were lower than the recommended allowances, 80 grams for adult and 45 grams for $4{\sim}6$ years childen, and animal protein intake of the all subjects was very much lower than the RDA. The main charecter of the diet has been found low in quality of protein and high in carbohydrate. The calcium intakes of the pre-school children in both villages, 251.9 milligrams in Siljun Ri and 218.8 milligrams in Soowol Ri, were very much lower than the recommended allowance of 500 milligrams per day. It is apparent that the diet for children should be supplemented with calcium. Among the vitamin group, the daily average intakes of vitamin A and $B_{2}$(thiamine), $B_{2}$(riboflavin), C(ascorbic acid), and niacin were not adequate for the children in both villages. Especially the intake of riboflavin, 0.4 milligrams in both village children, was much lower than the RDA, 0.9 milligrams per day. Physical Characteristics Average height, weight, chest and head circumference of the pre-school children in both villages were similar to those of the Korean standard given by the Korean Paediatrics Association except that the average height of pre-school boys in Siljun Ri was 8 cm higher than the Korean standard of 105 cm. The mean values of upper arm circumference and skinfold thickness of pre-school boys in both villages were the same, 15.4 cm for upper arm circumference and 6.8 mm for skinfold thickness, but the mean values of those of the girls in Siljun Ri were higher than those of pre-school grils in Soowol Ri. Biochemical Findings Avera ge hemogobin value of boys and girls in both villages was the same, 11.1 grams per 100 ml of blood. The incidence of anemia (Hb value below 11g/100ml) was similar in both viltagesr 36.4% for boys and 50% for girls in Siljun Ri and 37.5% for boys and 50% for girls in Soowol Ri. Average hemoglobin values of fertile women were 10.7g% in Siljun Ri and 10.8% in Soowor Ri. The incidences of anemia(Hb valre brlow 12g/100ml) were 100% in Siljun Ri and 86.7% in Soowol Ri. The anemia of these subjects may be caused mainty low intake of good quality protein and iron intake from vegetable food. Recommendation In general, the nutritional status of a community health pilot village is not higher than that of control village due to the lack of nutrition improvement guldance services. Nutrition education should be delivered to the villagers as a main part of the health education artivities. The emphasis should be on building better health through bttter food habits and better food production as well as on preventing malnutrition and diseasrs. It can be an invaluable part of community developnent. Since nutrition is considered to be at least one-half of MCH care, no village or home visits should be made without careful provision for teaching and demoastrating something simple and practical on nutrition. The nurse, midwife, and village health worker should be the chief promoters of nutrition.
