The study was conducted to evaluate differences of growth characteristics of rice cultivated in two different regions (Cheonan and Jeonju). It focused on nutritional composition and anti-nutritional factors of rice straw produced from 21 rice varieties including GM rice (Iksan 483). The range of general nutrition ingredient is that crude was 0.97 ~ 3.2 %, carbohydrate was 67.45 ~ 80.01 %, crude protein was 1.46 ~ 4.81 %, crude ash was 6.52 ~ 18.96 %, crude fiber was 25.77 ~ 40.02 %, NDF was 51.84 ~ 67.77 %, ADF was 27.11 ~ 40.44 %, calcium was 0.49 ~ 5.18 mg/g and phosphorous was 0.26 ~ 2.77 mg/g. The general nutritional contents of GM rice were included above range. The range of phytic acid of rice straws cultivated in Cheonan and Jeonju was 0 ~ 0.056 mg/ml and 0 ~ 0.059 mg/ml, respectively. The phytic acid content of GM was 0.033 mg/ml, which was in the range of the content of rice straw in Cheonan and Jeonju. The range of trypsin inhibitor of rice straws cultivated in Cheonan and Jeonju was 0.061 ~ 0.461 TIU/mg and 0 ~ 1.278 TIU/mg, respectively. The trypsin acid content of GM was 0.461 TIU/mg, which was in the range of the content of rice straw in Cheonan and Jeonju. In addition, we investigated microbial community from each soil sample by using metagenomics sequencing based on rRNA microbial diversity in order to inspect indirect changes of soil environment with cultivation of GM rice. Metagenomics analysis was carried out using soil samples cultivated with GM and non-GM rice for before transplanting, young panicle differentiation stage, heading stage, and ripening stage. Beta diversity of microbial community in both soil environments were calculated by using Bray-Curtis distance method and showed low value with an average of 0.24 (dissimilarity = 1). As a result, it was confirmed that the cultivation of GM does not give a significant effect on the change of microbial composition in soil. Therefore, Our study demonstrates that there is no difference in the composition of soil microorganism due to GM and non-GM rice.

본 논문에서는 탈북 성인 남녀의 평균 신장을 남한의 것과 비교 검토함으로써 영양 환경의 질이 향상되면 남녀 간 신장의 성적이형성 (SSD, Stature Sexual Dimorphism)이 커질 것이라는 영양환경 가설을 검증하였다. 연구대상 선정은 두 단계에 걸쳐 이루어졌다. 우선, 1997년부터 2007년 4월까지 남한에 입국하여 신체를 계측한 탈북자 중에서 탈북 당시 연령이 최소 만 20세 이상이어서 성인신장을 북한에서 도달한 것으로 추정할 수 있는 사람들을 일차 표본으로 선정하였다. 이 일차 표본 중에서 1955년에서 1959년 사이에 출생한 사람들과 1980년에서 1984년 사이에 출생한 사람들을 최종 선정하여 탈북자들 사이의 세대 간 변화를 비교하였다. 남북한 비교를 위해서는 남한의 Size Korea 2004 자료를 이용하였다. Size Korea 2004 자료에서 만20세 이상 성인으로서 탈북자 표본과 같은 시기 즉, 1955년에서 1959년 사이 그리고 1980년에서 1984년 사이에 출생한 사람들의 SSD를 계산하여 탈북자 자료와 비교하였다. SSD의 크기 변화를 통계적으로 검증하기 위해서는 Greene (1989)의 검증법을 이용하였다. 조사 결과, 탈북자들 사이에서는 한국전쟁 종전 직후 출생한 세대와 1980년대에 출생한 세대 사이에 평균 신장의 증가가 관찰되지 않았고 신장 성적이형성의 크기에도 변화가 없었다. 반면에 남한에서는 두 세대 사이에 평균 신장의 확연한 증가가 있었는데 남녀 중에서도 남성 집단의 평균신장 증가가 더욱 두드러진 결과로 SSD도 증가하였다. 즉 1980년대 출생자들이 한국전쟁 종전 직후인 1955~59년 사이에 출생한 사람들보다 확연히 큰 SSD를 보여주었다. 이는 영양 환경의 질이 향상되면 남성과 여성 사이의 성적 이형성이 커지는 경향이 나타날 것이라는 영양환경 가설을 뒷받침하는 결과이다.

This study was conducted to evaluate the efficiency of various inorganic and organic materials to improve physical properties of soil. Saline sodic soil (saturation percentage = 40.36%, $EC_e=5.15dS\;m^{-1}$, $pH_s=8.70$, $SAR=18.84(m\;mol\;L^{-1})^{1/2}$, bulk density =$1.49Mg\;m^{-3}$) was collected, brought to wire house and filled in pots after laboratory analysis for various parameters. Different sources of organic nutrients like farm manure (FM), press mud, compost, poultry manure and sesbania green manure were analyzed for their chemical composition. The experiment comprised of 12 treatments replicated thrice; $T_1$: control (recommended NPK), $T_2:{\frac{1}{2}}$ recommended NPK, $T_3$: FM at 1.5% by soil weight, $T_4$: pressmud at 1.5% by soil weight, $T_5$: compost at 1.5% by soil weight, $T_6$: poultry manure at 1.5% by soil weight, $T_7$: sesbania green manure at 1.5% by soil weight, $T_8:T_2$ + FM at 0.75% by soil weight, $T_9:T_2$ + pressmud at 0.75% by soil weight, $T_{10}:T_2$ + compost at 0.75% by soil weight, $T_{11}:T_2$ + poultry manure at 0.75% by soil weight, $T_{12}:T_2$ + sesbania green manure at 0.75% by soil weight. These treatments were applied using completely randomized (CR) design and appropriate time was given to decompose these organic nutritional sources. Seeds of wheat cultivar Sahar-2006 were sown. After harvesting the wheat, soil samples were collected from each pot and analyzed for various physical properties like bulk density, porosity and saturation percentage. An improvement in physical properties (bulk density, porosity and saturation percentage) of soil was noticed with the application of various organic nutritional sources but role of compost alone ($T_5$) remained prominent.

Mushrooms are ubiquitous in nature and have high nutritional attributes. They have demonstrated diverse biological effects and therefore have been used in treatments of various diseases, including cancer, diabetes, bacterial and viral infections, and ulcer. In particular, polysaccharides, including ${\beta}$-glucan, are considered as the major constituents responsible for the biological activity of mushrooms. Although an overwhelming number of reports have been published on the importance of polysaccharides as immunomodulating agents, not all of the healing properties found in these mushrooms could be fully accounted for. Recently, many research groups have begun investigations on biologically active small-molecular weight compounds in wild mushrooms. In this mini-review, both structural diversity and biological activities of novel bioactive substances from Korean native mushrooms are described.

이상의 결과를 종합해 볼 때, 쥐눈이콩은 조단백 및 조지방의 함량이 높고, 무기질이 풍부하며, 불포화지방산이 풍부하고 linoleic acid가 다량 함유되어 있었다. Glucose와 galactose가 주요 구성당이었으며, 12종의 지방산이 동정되었다. 쥐눈이콩 추출물의 항산화 활성을 탐색한 결과 종피 메탄올 추출물$(IC_{50}:\; 8.3\;{\mu}g/ml)$과 종피 75% 에탄올 추출물$(IC_{50}: 10.0{\mu}g/ml)$이 높은 항산화 활성을 나타내었다. 항산화 활성이 가장 높은 쥐눈이콩 종피 추출물을 용매분획하여 각 분획물에 대한 생리활성을 조사한 결과 에틸아세테이트 분획물에서 주된 활성이 나타났으며 페놀성화합물의 경우 100 g당 13.53 g으로 매우 높은 함량을 지니고 있었다. 쥐눈이콩의 생리활성 탐색결과 종피 부위에 다량의 페놀성 화합물을 함유하고 있으며 항산화 활성이 가장 높은 부위임을 규명하였다.

The purpose of this study was to compare student's satisfaction with school food service environment to improve the quality of middle school meal service. A survey was conducted of 680 students (boys 246, girls 433) from 6 middle schools providing school meals from October to November 2007. The questionnaires were directly distributed to the subjects for comparison of satisfaction of school meals depending on the eating place. As for the quantity of food, classroom group (3.40) expressed significantly higher satisfaction than cafeteria group (3.16, P < 0.01), but as for the satisfaction on hygiene, classroom group (2.76) showed significantly lower satisfaction than cafeteria group (3.03, P < 0.01). About the satisfaction of school meal environment, classroom group showed more satisfaction on distribution time, eating place, eating atmosphere (P < 0.001). The classroom group showed higher satisfaction than cafeteria group in cases of quantity, diversity of types of soup, dessert, and the cost of school meal. To improve eating place and hygiene of school meal, sufficient cafeteria space and pleasant environment is needed to be established.

Objective: The aim of this study was to evaluate the chemical-nutritional parameters, oxidative stability and volatile profile of eggs and cakes made with eggs from laying hens fed with a dietary supplementation of extruded linseed. Methods: Two thousand ISA Warren laying hens were randomly divided into two groups: a control group was fed with a standard diet while the experimental group received the same diet supplemented with 7% of extruded linseed. The trial lasted 84 days, in which three samplings of laid eggs were performed. Samples of eggs and food systems arising from eggs were then analyzed in order to obtain information about β-carotene and total flavonoid content, antioxidant activity, fatty acid profile, lipid oxidation, and volatile profile. Results: Linseed induced the increase of α-linolenic acid with consequent reduction of the ω-6/ω-3 ratio (4.3:1 in egg yolk); in addition to this, was evidenced the cholesterol reduction and the significant increase in total flavonoids and β-carotene, although no variations were detected in antioxidant capacity. Even in cooked products there was not only a direct effect of linseed in increasing α-linolenic acid, but also in inducing the reduction of cholesterol and its major oxidation product, 7-ketocholesterol. The dietary linseed integration was also shown to affect the volatile profile of baked products. Conclusion: Data confirmed that dietary supplementation with extruded linseed resulted in food products with interesting implications for human health. With regard to the volatile profile of baked products it would be necessary undertake further sensorial analysis in order to evaluate any variations on flavor and consumer acceptability.
