This study was conducted to examine the effects of a healthy dietary life and purchase of environmental-friendly food materials according to a mother's lifestyles of health and sustainability (LOHAS) attitudes. The subjects consisted of 295 mothers. The findings are summarized as follows. The mother's LOHAS attitude index averaged 3.39 points out of 5 points. High LOHAS attitude items were "I participate actively in separating the trash collection" (4.16 points), and "I recycle dresses that I do not wear by taking them to the recycling center" (4.08 points). In contrast, LOHAS attitude items for "I do community service activity on the weekend" (2.57 points), and "I try to serve in the local community" (2.63 points) scored very low. A high LOHAS behavior index occurred for mothers who were "resource saving", whereas "social welfare" scored low. Mother's intention to purchase environmental-friendly food materials averaged 3.61 points. Mother's health dietary life attitude score averaged 3.52 points. When age, monthly income, and the environmental-friendly food materials purchase ratio of the mother was high, the health dietary life performance was high. The LOHAS attitude index of mothers had an impact on the purchase intention of environmental-friendly food materials in resource saving and environmental-friendly oriented propensity groups. The LOHAS attitude index of mothers impacted healthy dietary life in environmental-friendly, family and health oriented propensity groups.

The aim of this study was to develop a KDPS (Korean dietary pattern score) to assess dietary patterns and diet quality of Koreans from a food culture perspective. The KDPS was applied to dietary data collected during the Korean National Health and Nutrition Examination Survey of 2007, and the validity and reliability of the KDPS were evaluated. The targets of the study included 2,278 Korean adults aged 20n89 years. The KDPS was developed using the sum of the scores of 13 components. Each component scored up to 10 points and there was a total of 130 points. The first seven components were for the KSMS (Korean-style meal score) and assessed the dietary balance based on the 3-Chup Bansang daily basic table setting. The components numbered 8 to 13 were for the FGS (food group score), which measured the degree of compliance with the six major food groups based on the Korean recommendation for one serving size of grains, meats, vegetables, fruits, milk, and oils. This KDPS was verified through content validity, concurrent-criterion validity, principal components analysis, and a reliability analysis. The results showed that content validity and construct validity were high. The KDPS developed in this study adhered to the Korean dietary pattern and a healthy diet intake. Furthermore, this study presented an integrated index by scoring the Korean style table setting in addition to evaluating meals from a nutrition perspective. This study can be extended to develop a score for assessing.

We investigated the effect of glutathione supplementation on feed intake, body weight gain, velvet antler yields and economics of elk yearling. Fourteen elk yearlings were divided into 2 groups. Seven yearlings in each group (control and treatment) were fed with 1.5-2.5 percent body weight (%BW) of concentrate feed for elk, voluntary intake of hay as roughage and 6 mg/kg body weight (KBW) of glutathione. The results were as follows. Average daily gain (ADG) for control elk yearlings for first 1.5 month was 0.46 kg, while that of glutathione supplemented was 0.55 kg. Although glutathione fed group had higher ADG compared to control group (p<0.05), ADG after 1.5 month showed no difference. In spring, daily DM intake per elk yearlings was 3.98 and 4.24 kg for control and glutathione supplemented groups, respectively. The statistical differences in feed intake between two groups were not observed. However, feed intake tends to increase in glutathione fed group. Production of velvet antlers for elk yearlings were 911±256 and 1066±357 g for control and glutathione supplemented groups, respectively. Statistical difference between two groups was not observed due to the high variation. In economic analysis, additional 109,110 KRW per head for the cost of glutathione resulted in 2 percent higher revenue index due to the increased antler production. In conclusion, feeding glutathione to elk deers effectively increased DM intake and ADG of elk yearlings. Glutathione supplementation in feed might increase velvet antler production as well as ADG.

본 연구에서는 azoxymethane (AOM)과 dextran sodium sulfate (DSS)로 유도된 대장 발암과정에 대한 셀레늄의 방어 효과를 조사하였다. 셀레늄 결핍(0.02 ppm Se), 정상(0.1 ppm Se), 과다(0.5 ppm Se)사료를 12주간 식이로 급여하여 혈액검사와 대장암 발생의 초기단계인 aberrant crypt foci (ACF)수를 측정했으며, 암 발생율을 조사하였다. ICP-AES 를 사용하여 간의 셀레늄 농도를 측정하였으며, 또한 셀레늄포함 항산화효소인 glutathione peroxidase (GPx) 활성을 알아보았다. 또한 TUNEL assay와 PCNA, β-catenin에 대한 면역조직 염색을 수행하였다. ACF 수 및 종양 발생률에 있어서, 셀레늄과다사료를 급여한 군이 정상셀레늄사료를 급여한 군보다 낮았으며, 셀레늄결핍사료를 급여한 군은 오히려 ACF 수 및 종양 발생률이 높았다. GPx 활성은 셀레늄의 섭취가 과다한 군에서 높게 나타났으며, 이 때, TUNEL 에서 apoptotic positive cell이 증가하는 것을 확인했다. 또 한 셀레늄의 섭취가 과다한 군에서 PCNA와 β-catenin의 발현이 감소됨을 볼 수 있었다. 본 마우스 모델실험에서 셀레늄은 여러 기전에 의해 대장암 발생을 억제할 수 있을 것으로 사료된다.

Banchandeungsok is a book written by a person who lived in the Cheongju area located in northern Chungcheong Province. The literature is regarded as a useful source for showing types of local food in the 1910s, so it was purchased by the National Folk Museum in 2007. The writer categorized dishes described in the recipe section of the book into side dishes, snacks, rice cakes, drinks, and miscellaneous. Following this, each category was distinguished by the name of the dish, the main material, the side material, and the cooking method is presented in tables. Thus, the food culture of Chungcheong Province was arranged based on the above categorized contents. The material from the product and the outside which grow spontaneously divided with the product which flows. The case which is a product the outside, went through what kind of process and could flow toward Sangshin village in Cheongju area probably, to observe tried. The area and time were clear Eumsikdimibang and Gyuhapchongseo Jusigui with comparisons. So tried to observe the time of 1910's Cheongju area culture Dietary life time and a regional feature.

This study investigated the food and dietary educational content in primary, middle and high school textbooks in order to provide fundamental data for the development of educational programs on Korean traditional food culture. The research objects consisted of 51 kinds of textbooks (15 kinds of primary school textbooks, 29 kinds of middle school home economics textbooks and 7 kinds of high school home economics textbooks), and the contents related to food and dietary education were counted and analyzed. The content analysis was performed using two categories: application method and subject matter. Application method included texts, cases, visual aids (pictures, photos, illustrations, chart, etc.) and activities, whereas subject matter consisted of seven types (well balanced nutrition and health, understanding of food and nutrition, cooking principles, cooking lessons, traditional foods and culture, others). The results of the application method in primary school textbooks show that visual aids were the most common in all six grades. For the subject matter, 'understanding of food and nutrition' was most abundant in primary school textbooks while 'well balanced nutrition and health' accounted for a large part of the contents in middle school textbooks. However, the contents regarding traditional foods and culture were insufficient in primary and middle school textbooks. These results suggest that educational contents on traditional foods and culture should be added to primary and middle school textbooks and covered in various subjects. Furthermore, high school 'home economics' contents need to emphasize comprehensive food and dietary education and adjust to 'science & technology for life'.

We surveyed 553 middle school students living in Incheon using questionnaires to compare their food behaviors and snack intake patterns according to weight groups based on BMI. Mean BMI was 20.3 for males and 19.6 for females. The rate of underweight, normalweight and overweight students was 33.3, 51.7, and 15.0%, respectively. Compared to the other two groups, the overweight students perceived their body shape more accurately (p<0.01). Regarding the reasons for skipping dinner, the most frequent answer by the underweight students was 'because of snacks', while that of the overweight students was 'to lose weight' (p<0.01). The normalweight students were found to eat a Korean traditional type breakfast more frequently than the other weight groups (p<0.05). The overweight female group was more likely to overeathabitually, whereas the normalweight and underweight groups tended to overeat when they were under stress (p<0.05). As for the amount of the snack intake, the overweight male students replied that they eat quite a lot of snacks. As a conclusion, the problems found in the underweight group were unbalanced diet and the disturbance of regular meal patterns due to inappropriate snack intake. The problems shown in the overweight group were overeating due to habit or stress, fast eating speed and large amount of snack intake.

The purpose of this study was to compare the awareness of dietary patterns and health of full-time and employed housewives. The investigation gathered information on general characteristics, dietary lifestyle, nutritional status, and health by questionnaire as well as anthropometric measurements. The subjects included housewives living in Seoul and Gyeonggi Province (86 full-time and 127 working housewives) during November 2009 to January 2010. The average age, height, and weight of the housewives were 45.8±7.6 yr, 161.0±8.4 cm, and 55.7±6.3 kg, respectively. The average monthly income of the households was 3 million to 5 million won (31.4% full-time and 37.0% working housewives), and their average food expense was 200,000 to 500,000 won (46.5% full-time and 48.1% working housewives). More than 90% of the studied homes were nuclear families and the most common number of children was 2 to 3 (79.1% full-time and 76.4% working housewives). The ratio of employed housewives who ate regular meals was 35.4%, but that of the full-time housewives was 48.2% (p〈0.05). Of the working housewives, 7.1% never ate breakfast and the primary reason for skipping breakfast was 'busy in the morning' (61.1%). The type of food that the housewives preferred when eating out was Korean food, both for the full-time and employed housewives (76.0%). All the housewives overate calories and the full-time housewives ate more protein, fat, vitamin A, vitamin B1, vitamin B6, niacin, vitamin C, vitamin E, folic acid, and cholesterol than the employed housewives (p〈0.05). Both the full-time and employed housewives were more satisfied with supper than with other meals. About 30.6% of the full-time and 33.9% of the working housewives had no interest in health, but answered that regular exercise was very important for health (33.3% full-time and 39.7% working housewives). In conclusion, working housewives have poor dietary habits and nutrient intakes, thus substantial measures to improve these problems are urgently needed.

본 시험은 산양유 생산을 위해 유기사료를 이용하여 유산양의 적정 에너지 및 단백질 공급 수준과 조농비율을 결정하기 위하여 비유중기 Saanen종 유산양 4두( BW)를 이용하여 라틴방각법으로 실시하였다. 대사에너지 공급수준과 단백질 공급수준을 10.59 (T1), 10.14 (T2), 9.45 (T3) 및 8.75 (T4) MJ/kg과 11.90 (T1), 12.73 (T2), 15.19 (T3) 및 16.60% (T4)로 달리하였으며, 조농비율은 49

The present study was carried out to investigate the effects of feeding dietary legislation sulfur on the lipid levels of chicken meat and growth performance in broilers. A total of 180 male broilers (Ross strain 308) were randomly assigned into three treated groups with triplicate of 20 birds each, T1 (control group), T2 (antibiotics 8 ppm), and T3 (0.3% sulfur premix containing 30% of sulfur) groups. The body weight gains over a 3-wk period were significantly higher in T2 and T3 groups than the T1 group, but not different between T2 and T3. The dressing percentage, weight of thigh meat, breast muscle and bursa of F were significantly high in T2 and T3 groups compared to the T1 group, but not different between T2 and T3. The weight of abdominal fat was significantly higher in T3 group than in T1 and T2 groups. The cholesterol content of the whole chicken meat was significantly lower in the T3 group as compared to the T1 and T2 groups. The oleic acid (18:1n-9) content of whole chicken meat from the T3 group was higher than that of the other groups. The results of this study suggests that feeding dietary sulfur as an antibiotic replacement may increase the oleic acid and reduce the cholesterol in chicken meat while improving the carcass characteristics and growth performance in broiler chickens

This study was conducted to investigate the effect of dietary sericite(SC) on laying performance, feed conversion ratio, egg quality and fecal ammonium nitrogen. Three hundreds and sixty 92-wk-old, Lohman Lite layers were randomly divided into 20 groups of 18 birds each and assigned to five experiment for 4 weeks (72 birds per treatment). Dietary treatments were Control (control diet), SC 0.5 (control diet +0.5% sericite), SC 1.0 (control diet +1.0% sericite), SC 1.5 (control diet +1.5% sericite), and SC 2.0 (control diet +2.0% sericite). Hen-day egg production tended to increase by the SC 1.0%, SC 1.5% and SC 2.0% supplementation in the diets. Egg weight also tended to increase by the SC 1.0% addition in the diets. Feed intake was increased (p<0.05) in SC 1.5 and SC 2.0 but feed conversion was improved (p<0.05) only in SC 1.0 (p<0.05). Digestibility of nutrients were not linearly affected by dietary supplementation of sericite although there was an inconsistent difference. Egg shell strength, albumin height, yolk color, and egg shell thickness were not affected (p<0.05) by treatments. Fecal NH3-N concentration was decreased (p<0.05) by dietary sericite supplementation compared to control. This study showed that dietary 1.0% sericite supplementation can be beneficial to improve egg production, egg weight and feed conversion and to decrease fecal NH3-N concentration.

A fiber fraction (Aloe cellulose), the by-product obtained from Aloe vera gel processing was freeze dried and investigated for in vitro glucose/ bile acid retarding effects of powdered sample (100 mesh) comparing with commercial α-cellulose as a reference sample. We also examined the effectiveness of physiological functionality such as the antiobesity and anti-constipation on Sprague-Dawley (SD) rat. The Aloe cellulose powders during in vitro dialysis experiment for 2 hours exhibited the glucose and bile acid retarding index of 20.32-35.2% and 53.13-28.30%, respectively. Especially, freeze dried aloe cellulose showed the 2.5 and 1.2-6 times higher effect on in vitro glucose and bile acid retardation than those of α-cellulose. These relatively good retarding effects on glucose and bile acid diffusion suggest a potential of preventing from diabetes and arteriosclerosis of some extent. Also, the results from animal experiments on SD rats fed a high-fat diet for 4 weeks suggested that Aloe cellulose might be used as a novel dietary fiber showing an effective anti-obesity and anti-constipation effect.

This study was conducted to examine the relationship between dietary habits and time spent watching TV and using internet, in elementary school children. The data were collected by a questionnaire survey of 712 elementary school children, within Gwangju and Jeonnam area. The SPSS 12.0/win program was used to analyze the 523 samples. Amount of TV-watching time was found to be related to the dietary habit score in the subjects. The children who watch TV “less than 1 hour/day” on weekdays had a better dietary habit score than those who watch TV “more than 1 hour” (p<0.0001). The children who watch TV “less than 2 hours/day” on weekends had a better dietary habit than the children who watch TV “more than 2 hours/day” (p<0.0001). The internet usage was also related to the dietary habit score in these children: those who use internet “less than 1 hour/day” on weekdays had a better dietary habit score than the children who use internet “more than 2 hours/day” (p<0.0001). The children who use internet “less than 2 hours/day” on weekends had a better dietary habit score than the children who use internet “more than 2 hours/day” (p<0.0001). These results indicate that the children tend to have a better diet when their TV and internet time is limited and thus healthy dietary behavior is negatively associated with a sedentary pattern of activity in elementary school children.

Iron catalyzes the production of free radicals, which can be related to a variety of pathological events, such as cancer and aging. The effect of dietary iron was investigated on formation of colonic aberrant crypt foci (ACF) induced by azoxymethane in male F344 rats. Animals were fed three different diets, including iron-deficient (3 ppm Fe), iron-normal (35 ppm Fe), and iron-overloaded (350 ppm Fe) diets for eight weeks. During the first and second weeks of the experiment, animals received two subcutaneous injections of azoxymethane (AOM, 15 mg/kg body weight) to induce ACF. After staining with methylene blue, the total numbers of ACF and aberrant crypts (AC) were counted on the colonic mucosa. Analysis of blood and serum was performed using a blood cell differential counter and an automatic serum analyzer. Iron-deficient diets induced a significant decrease in red blood cell counts and the values of hemoglobin concentration, hematocrit, mean corpuscular hemoglobin, and mean corpuscular volume, while an iron-overloaded diet did not affect these values. The iron-overloaded diet induced an increase in deposits of iron in the liver of rats, as determined by the ICP method and Perl’s staining. The numbers of ACF per colon showed a slight increase in iron-overloaded or iron-deficient rats, without statistical significance, compared to iron-normal rats. The number of total AC per colon in iron-overloaded rats was significantly higher than that in iron-normal rats (p<0.05). The number of large ACF (≥ 4 AC per ACF) in iron-overloaded rats was also significantly higher than that in iron-normal rats (p<0.05). These results suggest that dietary iron intake may play an important role in colon carcinogenesis in humans and animals.

본 시험은 산양유 생산을 위해 유가사료를 이용하여 유산양의 적정 에너지 및 단백질 공급 수준과 조농비율을 결정하기 위하여 비유중기 Saanen종 유산양 4두(57.5土10.8 kg BW)를 이용하여 4x4 라틴방각법으로 실시하였다. 대사에너지 공급수준과 단백질 공급수준을 10.59 (T1), 10.14 (T2), 9.45 (T3) 및 8.75 (T4) MJ/kg과 11.90 (T1), 12.73 (T2), 15.19 (T3) 및 16.60% (T4)로 달리하였으며, 조농비율은 49:51 (T1), 59:41 (T2), 74:26 (T3) 및 90:10 (T4)의 네 처리구로 나누었다. 사료 섭취량 및 체중은 모든 처리구 사이의 유의한 차이가 없었다. 유량은 T3구에서 가장 높았으며, T2 및 T4구와 비교 하여 유의하게 높게 나타났다(p<0.05). 유지방 함량과 생산량은 T4구에서 다른 처리구와 비교하여 가장 낮았다(p<0.05). 유단백질과 유당 생산량은 T1 (61.29 및 70.95 g/일)과 T3 (60.52 및 75.82 g/일)구에서 T2 (50.49 및 59.64 g/일)와 T4 (52.49 빛 59.82 g/얼)구와 비교하여 유의하게 높게 나타났다. 결과적으로 유산양의 유생산성을 극대화시커기 위해서 에너지 공급수준은 최소 9 MJ/kg 이상과 단백질 공급수준은 최소 15% 이상을 공급해 주어야할 것으로 기대된다.
