The purpose of this study is to discribe the nutritional status between female collegians on normal diet and lacto-ovo-vegetarian in the child bearing age. Physical examination, hematological parameters(hemoglobin, hematocrit, serum iron, serum albumin)and nutrient intake by dietary survey were carried out on each subject. Serum zinc, iron and copper concentrations were also determined. The results are summarized as follows : 1) Students on normal diet had higher values than lacto-ovo-vegetarian students in the height, weight, and skinfold thickness. 2) Hemoglobin, hematocrit, serum albumin values of the two groups showed no difference. But students on normal diet were higher in the serum irom and copper values than lacto-ovo-vegetarian students. 3) Serum zinc values differed significantly between the vegetarians and non vegetarians (Vegetarians') > non vegetarians') 4) On the nutrient intake of two groups, students on normal diet were higher than lacto-ovo-vegetarian students in the protein but students on normal diet were lower than lacto-ovo-vegetarian students in iron, vitamin A, $vitamin\;B_{2}$, vitamin C and crude fiber. 5) Intakes of calories and protein in the two groups were lower than RDA but Ca, vitamin A, $vitamin\;B_{1}$, $vitamin\;B_{2}$ niacin and vitamin C intakes of the two groups was higher than RDA. 6) Amounts of iron absorbed showed no difference in the two groups. But iron absorption rate was higher in students on normal diet than lacto-ovo-vegetarian students.

There is some evidence that phytostrogen plays an important role in bone metabolism in postmenopausal women. In this study, we investigated the phytoestrogen intake levels and the relation between dietary phytoestrogens intake and bone mineral density of vegetarian (n = 77) and omnivore postmenopausal women (n = 122 . Vegetarian women, all of them were seven day adventists, who had been on vegetarian diet (almost lacto-ovo vegetarians;a few vegans) oyer 20 yrs. The average age of vegetarians and omnivores were 62.3 yrs and 60.2 yrs, respectively and, there was no significant difference. However, body weight (p < 0.001), body mass index (p < 0.001) of vegetarians were significantly lower than those of omnivores. The mean daily energy intake of vegetarians and omnivores were 1386.1 kcal (76.3% of RDA) and 1424.5 kcal (76.9% of RDA), respectively. The mean calcium intake of vegetarians (456.7 mg, 66.3 % of RDA) was not significantly different from that of omnivores (453.5 mg, 65.2 % of RDA). The mean daily isoflavones (daidzein +genistein) intake of vegetarians and omnivore were 33.9 mg and 23.9 mg, respectively. The vegetarians consumed significantly greater quantities of isoflavones (p < 0.05) and lignans precursor (p < 0.05). In the vegetarians, intake of isoflavones was significantly positively correlated with BMD of femoral neck, after adjusted for age and BMI. Also lignan precursor intake of vegetarians was significantly positively correlated with BMD of spine, after adjusted for age and BMI. In conclusion, in omnivore post menopausal women, intake of phytoestrogen such as isoflavones and lignans was little low, and it is not clear that positive association with bone mineral density. But in vegetarian postmenopausal women, phytoestrogen intakes be important factors related to bone mineral density.

산업과 의학이 발전되면서 많은 인구는 삶의 질에 관심을 가지게 되었다. 건강에 대한 시각이 높아지면서 육류보다 채식 또는 식물성 오일을 선호하게 되었다. 오늘날 주로 니켈 촉매를 사용한 공정이 개발되면서 식물성 오일의 보존기간이 늘어나고 이동성이 편리해졌다. 현재 유지경화용 니켈 촉매는 외국기업이 세계시장을 장악하고 있다. 한편, 국내 니켈 촉매의 대량 생산 기술은 퇴보 되어 전량 외국에서 수입하고 있는 실정이다. 따라서 활발한 기초연구가 필요하고 국내에서 상용화 할 수 있는 촉매개발이 필요하다. 본 연구는 수소화 반응으로부터 유지경화에 기반이 되는 니켈을 주 활성 촉매제로 사용하였고, 희토류가 촉매의 활성에 주는 영향을 알아보았다. 일정량의 희토류는 니켈의 분산을 유도하여 효율을 증가시키고 조촉매로써 사용이 가능하였다.

본 논문은 한국 근대수학교육의 아버지 이상설(李相卨, 1870-1917)이 자연과학-물리학-에 기여한 내용을 다루고 있다. 이상설은 "수리(數理)"를 쓴 시기를 전후하여, 같은 시기에 붓으로 총 8면에 걸쳐 "백승호초(百勝胡艸)"라는 이름의 고전물리학 원고를 써서 남겼다. 분석결과 이 책의 원전은 1879년에 동경제대 의학부 교재로 발간된 "물리학(物理學)"이다. 이상설은 "백승호초"에서 먼저 개념을 정의하고, 일상에서 나타난 대표적 현상을 선록하여 한문으로 번역하였고, "물리학"의 전체 분량에서도 특히 '통유성(通有性)'에 중점을 두고 설명하였다. 동양에서 서양의 수리과학이 들어와야만 말할 수 있는 '질량보존의 법칙', '타성(惰性, 관성)'과 같은 고전물리학의 중요개념을 포함하는 내용이 19세기 말에 이미 이 책에 소개된 것으로 보아 이상설은 당대의 다른 저술에서 보기 힘들 정도로 당시 일반물리학의 최고수준의 원서를 통해 최신 정보를 수용하고 전파하기 위하여 노력하였음을 볼 수 있다.

본 연구는 사료내 마늘의 첨가가 육용계의 생산성 및 3-hydroxy-3-methylglutaryl coenzyme A(HMG-CoA) 환원효소에 미치는 영향을 구명하고자 실시하였다. 3주령의 육용계(Abor Acres) 50수를 처리구당 10수씩 마늘 0%, 0.3%, 0.6%, 1.0%를 첨가한 5개의 처리구에 배치하여 사료와 물은 자유채식시켰다. 사료섭취량, 중체량, 사료효율에 있어서 마늘 첨가에 의한 영향은 없었다. HMG-CoA 환원효소의 활성 및 간장과 혈청내 지질함량은 마늘 첨가에 의해 유의하게 감소되었다. 따라서 본 연구결과 마늘이 첨가된 사료를 급여한 육계의 혈액내 콜레스테롤의 감소는 HMG-CoA 환원효소 활성의 저하에 기인되는 것으로 사료된다.

The object of this experiment was to investigate the food habits of Korean native goats fed with various roughage sources. The experimental trials were conducted at Unbong Animal Genetic Resources Station in 2008. The experimental roughages include five sources and 25 species in all; grasses and legumes: 5 species (mixed grasses, orchardgrass, tall fescue, alfalfa, white clover), native grasses and weeds: 5 species (mixed native grasses, Miscanthus sinensis Anderss, Arundinella hirta (Thunb.) Tanaka, Barnyard grass, short awn, forage crops and straw: 5 species (barley + hairy vetch, wheat + hairy vetch, rye silage, barley silage, baled rice straw), browse and fallen leaves: 5 species (Mixed browse, Oriental white oak, Quercus serrta Thunb., Oriental cherry fallen leaves, Japanese chestnut fallen leaves), and imported hay and straw: 5 species(timothy hay, tall fescue straw, annual ryegrass straw, klinegrass hay, alfalfa hay). Ten Korean native goats were selected which had nearly the same body weight (average $24{\pm}2.8$ kg). The chemical composition and dry matter digestibility of each roughage source and species were significantly different at the sampling area, plant species, growth stages and cutting period (p<0.05). Among all the 25 species of roughages, the favorite intake species order by Korean native goat was observed like this: Quercus aliena, Querancas serrta Thunb and Mixed browse, which was a lower intake compared to other domestic herbivores. The Korean native goats ate more roughages which had low fibrous contents, but high dry matter digestibility. The Korean native goats ate more roughages which had low fibrous contents, but high dry matter digestibility. On the other hand, compared to each roughage source, total intake amount by Korean native goats was showed as browse and fallen leaves (33.1%) among trials roughage sources. Based on these results, the food habit of Korean native goats seems to be closer to the browser.

The object of this experiment was to investigate the food habits of sika deer fed with various roughage sources. The experimental trials were conducted at Unbong Animal Genetic Resources Station in 2008. The experimental roughages include five sources and 25 species in all; grasses and legumes: 5 species (mixed grasses, orchardgrass, tall fescue, alfalfa, white clover), native grasses and weeds: 5 species (mixed native grasses, Miscanthus sinensis Anderss, Arundinella hirta (Thunb.) Tanaka, barnyard grass, short awn, forage crops (hay, silages and straw): 5 species (barley + hairy vetch, Wheat + hairy vetch, rye silage, barley silage, baled rice straw), browse and fallen leaves: 5 species (mixed browse, oriental white oak, Quercus serrta Thunb., oriental cherry fallen leaves, Japanese chestnut fallen leaves), and imported hays and straws: 5 species (timothy hay, tall fescue straw, annual ryegrass straw, klinegrass hay, alfalfa hay). Five sika deer were used as experimental animals and the averaged body weight was 95+5.4kg. The chemical composition and dry matter digestibility of each roughage source and species were significantly different at the sampling area, plant species, growth stages and cutting period(p<0.05). The sika deer ate more roughages which had low fibrous contents, but high dry matter digestibility. Among all the 25 species of roughages, the favorite intake roughage sources ranking by sika deer was observed like this: browse and fallen leaves (32.2%), grass and legumes (27.0%), native grasses and weeds (22.0%), imported hays (12.9%) and forages crops (5.5%) respectively. Although, the sika deer ate more browse leaves, but ate more roughage which had low fibrous contents (NDF and ADF), but high drymatter digestibility. On the other hand, compared to each roughage source, total intake amount by sika deer was showed as browse and fallen leaves (32.2%). Based on the result, the food habit of sika deer seems to be closer to the typical browser.

The purpose of this study is to verify the relation between vegetarian diet and the risk factors of cardiovascular disease. To do the present study the vegetarians were selected;245 Buddhist nuns(age: 23-79yrs). For control subjects, 235 healthy female adults(age: 23-79yrs) were selected. They were the teachers, the nurses and the housekeepers living in Chinju Gyeongsang Namdoo Province. Study period was from October 1996 to February 1997. The contents are consist of survey, anthropometric measurement, and clinical examination. The average ages of the subjects were 44.20yrs for vegetarians and 40.52yrs for non-vegetarians respectively. Average body mass indice(BMI) of vegetarians and non-vegetarians were 22.47 and 21.08, WHR was 0.85 and 0.84, percentage of body fat was 28.79 and 26.55 and the average duration of vegetarian diet of the vegetarians was 13.16 years. On the nutrient related lipid, fat, the energy ratio of fat, saturated fatty acid, total fatty acid, monounsaturated fatty acid and total-cholesterol were significantly lower(p<0.01) but the ratio of p/s was significantly higher(p<0.01) in vegetarians than non-vegetarians. The vegetarians were significantly higher than the non-vegetarians in intake of fiber, vitamin C. In vegetarians, variables that significant negative correlation with fiber were total-cholesterol, AI, blood sugar. In non-vegetarians, variables that significant negative correlation with fiber were TG, total-cholesterol, blood sugar, systolic blood pressure. In both subjects, the serum lipid concentration and the blood pressure were getting lower with fiber intakes. Consequently, vegetable diet can be considerably effective in making the level of the risk factors causing in cardiovascular disease lower. (Korean J Nutrition 34(3) : 313∼321, 2001)

The prevalence of chronic diseases have been rising in the developing countries because of their increased animal foods consumption and Western lifestyle. Lately, vegetarian diet that exclude animal products get public attention. The purpose of this study was to evaluate the nutritional status and dietary quality of vegetarians, and their consumption of vitamin K and was also assessed. Vegetarians including strict vegan and lacto-ovo-vegetarian consumed their diet at least over 6 months. Carnivores were gender and age matched with vegetarians and they consumed over 50% of protein and fat from animal sources. Current nutrient intakes and dietary quality were assessed using 3-day food records and intake of vitamin K was calculated from the data base of 'Provisional Table on the vitamin K contents of foods, USA'. Blood sample were collected and biochemical parameters and plasma phylloquinone concentrations were analyzed. Anthropometric data from vegetarian and carnivore were not significantly different. The intake of calories, protein, vitamin $B_2$, Ca and Zn of the vegetarians were remarkably lower than RDA for each nutrient. Moreover, index of nutritional quality and nutrient adequacy ratio of vegetarians were lower than those of carnivore. Vegetarian consumed less fat and the ratio of n-6/n-3 fatty acid was lower in vegetarian. The intake of essential amino acids in vegetarian was significantly lower than that of carnivore. The vitamin K consumption and plasma phylloquinone concentration of vegetarian were significantly higher than those of carnivore (p<0.05). The dietary vitamin K consumption was positively correlated with plasma phylloquinone levels in vegetarian (p<0.01).
