The purpose of this study was to investigate the dietary habits, health status, and nutrients status of male college students in Seoul according to vegetarian habits. The heights of lacto-ovo vegetarian and non-vegetarian students were not significantly different. However, body weight was significantly higher in the non-vegetarians. The lacto-ovo-vegetarians were vegetarians for religious reasons, and indicated 86.0% satisfaction with their meals. However, the lacto-ovo vegetarian and non-vegetarians showed concerns about low nutrient intakes. Lacto-ovo vegetarians displayed a higher proportion of meal regularity and daily breakfast as compared to non-vegetarians. In addition, their favorite food when eating out was Korean food. Lacto-ovo vegetarians showed higher intakes of milk or other dairy products (yogurt, etc.), vegetables, and fruit, as well as more regular eating habits. In contrast, the non-vegetarians showed higher intakes of high-protein foods (eggs, beans, tofu, etc.) and fatty foods. Lacto-ovo vegetarians showed lower intakes of total energy, as well as vitamins $B_2$, $B_6$, and niacin. Non-vegetarians showed in sufficient dietary fiber intake. In conclusion, lacto-ovo-vegetarians need a meal plan to consider the intake of other nutrients, while non-vegetarians should try to prevent the occurrence of health problems due to excessive intake of nutrients.

The purpose of this study was to propose an alternative for the eating habits of modern people and coping with the diseases. The purpose of this study was to apply the principles of eating habits of people living in Roma Linda to modern dietary life and to help healthy life and prevent disease. The period of this study was from May 1, 2016 to February 28, 2018. Literature search was conducted using Pubmed and Korean academic web sites. Based on the recognition of wrong eating habits, we classify and classify diseases according to eating habits. A total of more than 100 papers were selected and 60 papers and a database were prepared. People living in Roma Linda have eight health principles. The Roma Linda practiced balanced nutritional intake, sufficient exercise, adequate water intake, sunlight, temperance (abstinence from alcohol etc.), fresh air, adequate rest, and trust in eating habits. People living in Roma Linda have a high intake of vegetables, fruits and nuts. People living in Roma Linda are educated about nutrition, and among them, there is a low prevalence of coronary heart disease and cancer, because they mostly do not smoke or drink alcohol. Unhealthy eating habits and dietary behavior are associated with many diseases. Many chronic, degenerative diseases are due to bad eating habits and stress. If you take good food habits of people living in the Roma Linda area and practice it steadily, it will have a great effect on disease prevention.

This study was conducted to clarify the characteristics of bird communities due to different habitat types on 3 sites in Han river area from May 2001 to January 2002. Water area was the most dominant habitat type in each site and also forest was dominant habitat type in site 1(Paldang area). Site 2(Bam island area) had various habitat types e.g. shrub field sandv plain, reed bed and grass field. Total 52 bird species were recorded on 3 sites in Han river. Ducks were the most dominant species, especially in January 2002. Density of individuals were higher in site 1 and 2, but lower in site 3(Nanjido area). In January 2002, dabbling ducks were dominant in site 2, and diving ducks were in site 1. Among diving ducks, common merganser Mergus merganser showed high density in site 2 and pochard Aythya ferina did in site 1. In site 1, coot Fulica atra showed also high density Diverse habitat types could be support foraging resources for dabbling ducks in site 2. High density of pochard and coot would be related to abundant aquatic plants and stable water depth in site 1. Manipulation of riparian zone in site 3 into natural vegetation would increase the bird species diversity. By the manipulation of habitat, habitat potentiality of birds would be increase in Han river area.

This study was conducted to evaluate the effects of feeding rye silage and feed restriction on both growth and reproductive performances in replacing gilts. Twenty four replacing gilts (Landrace×Yorkshire, 67.63±1.17kg initial BW) were used in 49 d growth assay. Dietary treatments were included 1) CON(basal diet), 2) S15(15% feed restriction + ad libitum rye silage) and 3) S30(30% feed restriction + ad libitum rye silage). In growth performance, average daily gain and average daily feed intake were the highest in CON among treatments(P<0.05). Average daily silage intake was not significantly different between S15 and S30 treatments(P>0.05). Feed conversion ratio was the lowest in CON among treatments(P<0.05). Average silage intake of S15 and S30 treatments was increased as time goes by(P<0.05). While all gilts of S15 and S30 treatments became pregnant, one gilt of CON became pregnant. Also, first estrus and mating were occured earlier in S15 and S30 than those of CON. In conclusion, 15% feed restriction and feeding rye silage reduced growth performance, reached earlier to first estrus and increased pregnancy rate in replacing gilts.

The purpose of this study was to evaluate on nutrient intake status and diet quality of middle and old aged vegetarian women in Korea, The research group was composed of vegetarian women (n=91), all of them were Seven Day Adventists, who had been on vegetarian diets, over 20 yrs. Their anthropometric measurements, dietary intakes, and diet quality indices were compared to omnivores (n=122). The average age of vegetarians and omnivores were 61.8 yrs and 60.3 yrs, respectively. The mean daily energy intakes of vegetarians and omnivores were 1428.8 kcal and 1424.5 kcal, respectively and there was no significant difference. The vegetarians consumed significantly lower intakes of protein (p < 0.05), zinc (p < 0.001) and vitamin $B_{2}$ (p < 0.05) compared to omnivores. In the diet quality, zinc and vitamin $B_{2}$ nutrient adequacy ratio (NAR) of vegetarians were significantly lower than those of omnivores. Mean adequacy ratio (MAR) of vegetarians and omnivores were 0.80 and 0.77, respectively and there was no significant difference. The KDDS (Korean's Dietary Diversity Score) of vegetarians and omnivores were 3.7 and 4.0, respectively, and there was significant difference (p < 0.01). The KDQI (Korean's Diet Quality Index) of vegetarians (1.5) was significantly lower than that (2.1) of omnivores (p < 0.001). In conclusion, vegetarian women have low intake status of protein, zinc and vitamin $B_{2}$, and partly low diet quality. Therefore it was needed that well planed diets to replace the nutrients supplied from excluded food groups in middle and old aged vegetarian women.

This paper deals with contents that Sang-Seol Lee contributed to the natural science in the 19th century Korea. Prof. Sung-Rae Park, the science historian, called Sang-Seol Lee Father of the Modern Mathematics education of Korea. Sang-Seol Lee wrote a manuscript Botany with a brush in late 19th century. Botany was transcribed from Science Primers: Botany (written by J. D. Hooker), which is translated into Chinese by Joseph Edkins in 1886. The existence of Sang-Seol Lee's book Botany was not known to Korean scientists before. In this paper, we study the contents of Botany and its original text. Also we analyze people's level of understanding Western sciences, especially botany at that time. In addition, we study authors of 16 Primers jar Western Knowledge. We study the contribution of mathematician Sang-Seol Lee to science education in the 19th century Korea.

An experiment was conducted to evaluate condensed molasses solubles(CMS, a by-product from monosodium glutamate production) as a source of nitrogen for ruminant with particular reference to its effects on microbial protein synthesis. Four non-lactating dairy cows fitted with rumen cannulas were used in a 4 ${\times}$ 4 Latin square with 14-day periods. The four treatments were (1) basal diet consisting of barley straw ad libitum and 3 kg/d of rolled barley, (2) basal diet plus 200 gld molasses and 300 g/d water, (3) basal diet plus 200 g/d molasses, 100 g/d CMS and 200 g/d water, (4) basal diet plus 200 g/d molasses, 200 g/d CMS and 100 g/d water. Ruminal pH remained at high levels and showed little variation during the day between treatments. The concentration of total and individual VFA in the rumen was similar between treatments. There was no difference in the concentration of ammonia in the rumen between treatments, although the intake of nitrogen in molassesl CMS mixture treatments was higher than that of control and molasses treatment. But there was a suggestion of an increased synthesis of microbial protein with the higher level of inclusion of CMS when the allantoin/creatinine ratio was used as an index of microbial protein production(P <0.10).

This study was carried out to evaluate effect of dietary green tea by-products (GTB) on laying performance and quality of eggs in hens. A total of 96 laying hens (22-week-old) "Tetran Brown" were allotted to four dietary treatments, which containing 0, 2, 4 and 6% green tea-by products. The results showed that the egg production increased (P＜0.05) in layers fed diets containing 4% or 6% green tea-by products compared to the layers fed control no GTB. Egg weight and egg mass in layers fed diets containing 2% green tea by-products significantly decreased compared to those in the other groups (P<0.05). The feed intake was lower in layers fed diets containing 2% and 6% green tea by-products. The feed conversion ratio was lower (P<0.05) in layers fed diets containing 4% or 6% green tea by-product supplementation respectively. The egg shell thickness was no significantly different between layers fed the control and green tea by-product diets (P>0.05). The egg yolk cholesterol tended to decrease when layers fed diets containing green tea by-products, although the differences were not significant (P＞0.05). The linolenic and docosahexaenoic (DHA) acid contents in egg yolk significantly increased in layers fed diets containing different levels green tea by-products compared to those fed control diet (P<0.05). These results suggest that inclusion of green tea by-products in layer diets is suitable for hens without negative effects on egg composition.

Infants and children with food related Atopic Dermatitis (AD) need extra dietary efforts to maintain optimal nutrition due to food restriction to prevent allergy reactions. However, nutrition ignorance and food faddism make patients even more confused and practice desirable diet more difficult. The objective of this study was to report the AD patients' malnutrition cases in Korea. We report on 2 cases of severe nutritional deficiency caused by consuming macrobiotic diets which avoid processed foods and most animal foods, i.e. one of vegetarian diet. Case 1, a 12-month-old male child, was admitted with severe marasmus. Because of a history of AD, he was started on mixed grain porridge at 3 months without any breast milk or formula feeding. His caloric intake was 66% and protein intake was 69% of the recommended dietary allowance. Patient's height and weight was under 3th percentile. On admission the patient was unable to crawl or roll over. Case 2, a 9-month-old AD female patient, was diagnosed with kwashiorkor and rickets. She was also started on mixed grain porridge at 100 days due to AD. Her caloric intake has been satisfied recommended dietary allowance until 7 months, however, she conducted sauna bath therapy and reduced both energy and protein intake at 8 months. The amount of protein intake for case 2 was higher than recommended dietary allowance, but, sauna therapy and severe AD with intakes of low guality protein may increase patient's protein requirement resulting in kwashiorkor. Case 2 patient's height and weight was on 3th percentile. Both cases showed low intake of calcium, iron, zinc, vitamin A, vitamin E and especially very low intake of vitamin B$_{12}$ and vitamin D. Allergy tests for certain foods had not done prior to admission for both cases. They followed the dietary advise operated by macrobiotic diet internet site. In conclusion, AD infants' parents and caregivers should contact a pediatrician trained as a specialist in allergy for accurate diagnosis. For infant patients, breast or formula feeding including hypoallergenic formula should be continued until their one year of age. When certain foods need to be restricted or to follow special diets such as vegetarian diet, consultation with pediatrician and dietitian is needed.d.
