The goal of this study was to find the way of reduction on food waste in the university cafeteria. A survey was conducted on the 502 students using Yeungnam University cafeteria, and illustrates the students' use and perception for the reduction of food waste. Its results can be summarized as follows: 57.2 percent of the total users use the university cafeteria every day, also 77.1 percent of the students preferred Korean style dish. Female students left more food waste than male students, and the most leaving food was stews than the other types of foods. The most favorite stew and side dish turned out to be Yukgaejang and Bulgogi respectively, also they preferred Kimchibokkumbab. But they disliked Baechuguk, Sungiguk, salted fish and fishes. The perception of female users on the reduction of food waste was lower than that of male users, but they were concerned about on the reduction and recycling of food waste. Also the best method of food waste treatment recognized by students were utilizing the waste food as fertilizer or fodder for animals.
This study was conducted to investigate the nutritional constituents of pine pollen and the effects of pine pollen on rat liver. Using the chemical components analysis method, the constituents of pine pollen are crude protein (13.97%), crude lipid (6.50%), crude ash (3.25%). Detectable in pine pollen are main fatty acids and non-essential amino acids such as glutamic acid and aspartic acid such as oleic and linoleic acid and 18 kinds of amino acid including essential amino acids. The effects of pine pollen on rat liver fed with a high fat diet for 6 weeks showed significant decrease in total lipid and triglyceride as compared with the group fed with a fat diet only. Total cholesterol content decreased by 20.33%. No significant difference was found in total protein content of each group. Pine pollen is efficacious in preventing geriatric diseases (arteriosclerosis, hyperlipidemia and cardiovascular system-related diseases).
6주간 고지방식 이와 송화분을 투여한 흰쥐의 간장에 미치는 송화분의 효과를 관찰하였다. 간장에서의 total lipid, triglyceride의 농도는 고지방 식이군과 비교했을 때 유의성 있게 감소하였고, total cholesterol 농도도 감소하는 경향을 나타내었다. total protein농도는 각 군간에 차이가 없었다. 간장의 조직학적 관찰에서,고지방 식이 투여한 군에서는 심한 조직의 지방 침착을 보였으며, 송화분과 고지방식이 병용 투여군에서는 다소 억제하는 경향을 보였다. 이상의 결과로 송화분은 고지혈증 및 순환기계 질환의 예방에 효과가 있는 것으로 사료된다. Effect of pine pollen on lipid accumulation and metabolism in liver investigated with rats fed high fat-supplemented diets for 6 weeks. Concentrations of total lipid and triglyceride in liver significantly decreased in the experimental groups(treated with pine pollen) compared with the control group. Concentration of total cholesterol showed a little decreasing. It was observed from photographs of hepatic tissue in rats that pine pollen inhibits the lipid accumulation induced by high fat diets.
This paper was studied to investigate the chemical component of pine pollen used one of sturdy food like nutrition and a hematic from ancient days in order to develop and utilize and compared natural pine pollen with water washed pine pollen as indicated in the book "Imperial court cookery" The results are summarized as follows ; Chemical composition of natural pine pollen was 9.4% moisture, 66.8% carbohydrate, 13.9% crude protein and 6.5% crude lipid and that of water-washed pine pollen was 47.7% moisture, 32.7% carbohydrate, 10% crude protein and 5.0% crude lipid. In natural pine pollen major fatty acids were oleic acid(32.2%), linoleic acid(25.6%). Major fatty acids of total lipid, neutral lipid, glycolipid and phospholipid in water-washed pine pollen were linoleic acid(35.7%) and oleic acid(33.5%) Natural and water-washed pine pollen did not show any differences in chemical composition.
This study was carried out to get a industrial information about a possibility of IgY antibody production, antimicrobial activity and properties of IgY antibody in egg yolk. After the initial immunization the anti-Salmonella typhimurium IgY antibody level gradually were decreased from firth week to tenth week. On the other hand, the antibody level in the serum were increased from the first week, reaching its peak in the sixth week. Molecular weights of IgY were estimated approximately 72~75KD in a heavy chain and 30~40KD in a light chain by electrophoresis.
RNA Synthesis in the nuclei of newly hatched chicken liver is enhanced by the food intake and age related changes. The enhanced RNA Synthesis was ascribed not'to the increase in the activity of solubilized DNA - -dependent RNA polymerase but to the increase in the initiation binding site of RNA synthesis.
세포증식에 관한 개체발생의 일주림듬을 검토하기 위하여 부화직후의 병아리 간장 DNA 합성 리듬 및 간 세포증식의 개체발생에 대해서 검토한 결과 포유류에 있어서 DNA 합성 리듬은 이유기 후기에 출현하는데 비하여 조류(병아리)에 있어서 DNA 합성 리듬은 부화 12시간후 바로 출현하였고 간장의 DNA 합성 리듬은 사료섭취에 의해 리듬주기가 유지되었다. 한편 DNA 합성 활성은 절식에 의해 감소되었으며 DNA 합성의 리듬변화는 사료섭취에 의해서도 변화하였지만 빛의 조건에 의해서도 많은 영향을 받았다. 이러한 간 DNA 합성은 12시간 늦은 위상에 유사분열도 동반하였다. The division and circadian DNA-synthesis rtythm are studied in chick liver immediately after hatching. The division function is tested by the mitotic and the ³H-thymidine labelling index. The DNA synthesis exhibited a cyclic variation of 12 hours immediately after hatching. The rhythmic changes of DNA synthesis was maintained in the liver of meal-fed chickens, but the DNA synthetic activities decreased gradually in the starved chicken liver. From this time, the rhythm of DNA synthesis was greatly afffected by lighting schedule, all these DNA synthesis of chicken liver was accompained by mitosis.
