본 연구에서는 조리조건에 따른 은행의 이화학적, 독성 및 항산화적 변화를 살펴보기 위해 삶기, 찌기, 볶기 3가지의 조리법과 각 조리법 별 5가지 조리시간을 설정하여 조리조건에 따라 조리된 은행에 대해 분석을 진행하였다. 은행의 외관 변화를 보기 위해 색도 분석을 진행하였고, 독성은 MPN 함량, 항산화적 변화는 DPPH radical 소거능과 총 페놀 화합물 및 총 플라보노이드 함량을 측정하여 비교하였다. 은행의 외관 변화를 감지할 수 있는 색도의 경우, 볶기가 가장 큰 변화를 보였다. 고온으로 인해 표면이 갈색으로 변하여 L 값이 감소하고 a값이 큰 폭으로 증가하는 경향을 보였다. MPN 함량은 볶기가 단시간 동안 큰 감소를 나타내었으며 특히 8분에서 MPN 함량이 큰 폭으로 감소하였다. DPPH radical 소거능은 11분간 볶은 은행에서 기능이 유의적으로 증가한 뒤 14분까지 생물 및 다른 조리조건에 비해 높은 값을 보였다. 총 페놀 화합물 함량은 30분 이내로 찌거나 11분 이내로 볶았을 때 그 함량이 유의적인 차이 없이 유지되는 것으로 나타났고, 총 플라보노이드 함량은 11분 동안 볶은 은행에서 그 함량이 유의적으로 증가한 뒤 14분까지 높은 값을 나타내었다. 이상의 결과를 바탕으로 조리시간 대비 변화가 크게 나타나는 조리법은 볶기인 것으로 나타났으며, 시간대비 변화가 가장 적은 조리법은 찌기인 것으로 나타났다. 또한 은행의 독성 함량 감소 및 항산화 활성 증가를 위한 최적의 조리 조건은 8분-11분간 볶는 것으로 분석되었다. 본 연구를 통해 서로 다른 조리조건에 따라 은행 속 독성 함량 및 항산화 활성이 변화하는 것을 확인할 수 있었으며, 이러한 변화 양상에 대한 분석은 추후 연구의 기초 자료로서 활용할 수 있을 것으로 사료된다.

There has been an increase in the viewing of YouTube content among children and adolescents. This, coupled with the popularity of live-streamed video content such as mukbang, where viewers watch the host eat, has raised concerns about media addiction and the indiscriminate imitation of eating behavior. Therefore, there is a need for guidance on the appropriate behavior for viewing YouTube food content to promote healthy eating habits among children. In this study, we aimed to compare the patterns of the main caregivers and their children while viewing media and investigate the impact of viewing YouTube food content on the physical and mental health of the children. The findings suggest that active YouTube food content viewing by the main caregivers may reduce imitative behaviors due to passive media consumption by their children. This study provides valuable insights by comparing and analyzing the YouTube content viewing of the main caregivers and their children. The results can be used as a basis for the development of lifestyle-centered guidelines for children. However, it is important to note that this study was conducted during the coronavirus disease (COVID-19) pandemic when there was a significant increase in the use of media, which is limitation of the study.

Among the nutrients in feed, amino acids and minerals are important for the growth and development of pets. In particular, interest in nutritional components related to the health of pets is increasing as pet-raising households and pet food markets have recently grown. Therefore, in this study, 55 pet food products distributed in South Korea were purchased, and the content of 3 essential and conditionally essential amino acids (taurine, lysine, arginine) and 4 minerals (Ca, P, Na, K) was investigated. Among the three amino acids, arginine was found to have the highest content, and the average content was 1.79 and 1.37 % in cat and dog foods, respectively. On the other hand, the taurine content was the lowest, but it was found to be higher than the minimum requirement of 0.10 % for cats set by the American Association for Feed Control (AAFCO) and the European Federation of Pet Food Industries (FEDIAF). As a result of the four-component analysis of minerals, the content of Ca was found to be the highest, and the average content was confirmed to be 1.64 and 1.25 % in cat and dog food, respectively. On the other hand, Na was the lowest, but it was higher than the AAFCO minimum requirement and FEDIAF minimum requirement for young cat and dog food. Among all 55 samples examined, the content of the three amino acids and the four inorganic components was confirmed to be suitable for the recommended minimum intake and maximum allowable intake presented by AAFCO and FEDIAF.

The major goals of the poultry industry are to increase the carcass yield and to reduce carcass fatness, mainly the abdominal fat pad. The increase in poultry meat consumption has guided the selection process toward fast-growing broilers with a reduced feed conversion ratio. Intensive selection has led to great improvements in economic traits such as body weight gain, feed efficiency, and breast yield to meet the demands of consumers, but modern commercial chickens exhibit excessive fat accumulation in the abdomen area. However, dietary composition and feeding strategies may offer practical and efficient solutions for reducing body fat deposition in modern poultry strains. Thus, the regulation of lipid metabolism to reduce the abdominal fat content based on dietary composition and feeding strategy, as well as elucidating their effects on the key enzymes associated with lipid metabolism, could facilitate the production of lean meat and help to understand the fat-lowering effects of diet and different feeding strategies.

The aim of the present investigation was to see whether an anabolic steroid, nandrolone phenylpropionate (NPP), exerts protienanabolic effects under such adverse nutritional conditions as protein deficiency and protein-energy malnutrition in male rats. feeding on a low-protein (8% casein) diet resulted in a marked reduction in body weight gain that was associated with reductions in body protein and protein content of gastrocnemius muscle. Administration of NPP (4 mg/kg body weight) did not alter muscle and body protein depletion induced by a low-protein diet. 50% food restriction caused reductions in body protein and in protein content of gastrocnemius muscle. These reductions were partially prevented by NPP (4 mg/kg body weight). Food restriction did not affect plasma concentration of corticosterone, insulin, or tetosterone plus dihydrotestosterone. On the other hand, neither plasma concentration of corticosterone nor insulin were affected by NPP. The present results show that anabolic steroids do not express anabolic effects under conditions of protein deficiency, but in protein-energy malnutrition, anabolic steroids exert their anabolic effects even in male rats.

In this study, the nutritional composition of colostrum milk obtained from 22 mothers delivering perterm infants and 17 mothers delivering term infants was analyzed. The energy content of colostrum was yielded based on nitrogen, lactose, and lipid data. Preterm milk is more close the nutritional needs of the preterm infant than dose other breast milk. The results are as follows : 1) Protein concentration was significantly higher, but carbohydrate and lipid concentration were lower in preterm milk than fullterm milk. Energy content yielded from total nitrogen, lactose and lipid concentration was higher in the fullterm milk than preterm milk. 2) Calcium was higher in the preterm milk than fullterm colostrum. Phosphate was lower in fullterm milk than pretem milk. Calcium/Phosphate ratio were 2.61/1 in the preterm and 2.06/1 in the fullterm milk. Magnesium was higher in the preterm milk than fullterm milk. Zinc, Copper and Manganese concentrations were tended to lower in the preterm milk than fullterm milk.

This study was performed to assess the nutritional status and hair mineral content of children with behavioral problems and compare the values with a gender, age-matched control group. The subjects were recruited from S elementary school children in Seoul, Korea. Students scored higher than 60 points were diagnosed with behavioral problems according to the Korean-Child Behavior Checklist. Nutritional assessment of the two groups (behavior problem group: male n=15, female n=24; $9.6{\pm}1.6$ years, control group: male n=16, female n=18; $9.5{\pm}1.9$ years) was performed using a nutritional survey and by measuring hair mineral contents. In the results, food frequency questionnaire analysis showed that the intakes of anchovy (P<0.05), soybean curb (P<0.01), radish (P<0.05), bean sprouts (P<0.05), spinach (P<0.05), carrot (P<0.05), pumpkin (P<0.05), lettuce (P<0.05), cabbage (P<0.01), apple (P<0.05), and milk (P<0.01) were higher in the control group than the behavior problem group, whereas intakes of ramyeon (P<0.05), cookies (P<0.05), and coke (P<0.01) were higher in the behavior problem group than the control group. Intakes of most nutrients such as plant-derived protein (P<0.05), fiber (P<0.05), plant-derived calcium (P<0.05), phosphorus (P<0.05), plant-derived iron (P<0.05), vitamin B2 (P<0.05), vitamin B6 (P<0.05), vitamin C (P<0.01), vitamin E (P<0.05), and folate (P<0.05) were significantly higher in the control group than the behavior problem group. Hair analysis showed that the levels of arsenic (P<0.05), mercury (P<0.001), uranium (P<0.05), iron (P<0.001), boron (P<0.01), and germanium (P<0.001) were lower, but the levels of phosphate (P<0.05), chromium (P<0.001), sodium (P<0.05), and sulfur (P<0.001) were higher in the behavior problem group than the control group. Conclusively, behavioral problems constitute a complicated condition in which nutritional factors may play major roles. However, it is still under investigation as to whether or not modification of dietary habits or nutritional supplementation can improve children's behavior, since symptoms require a broad understanding of the environmental and genetic interactions.
