This study was conducted to estimate the effects of genotype for chicken major histocompatibility complex (MHC) B-LB genes on economic traits. To detect polymorphism, 400 bp fragments of MHC B-LB genes were obtained and sequenced. After digestions using restriction enzyme Hea III, two restriction enzyme sites were observed. There were two mutations at position 427 and 651 those were decided as Type I and Type II, respectively. Using RFLP analyses, type I were genotyped to TT, TC and CC, and type II to MM, Mm and mm. The relatively higher TC genotype frequencies (0.8) of Type I and Mm genotype frequencies (0.88) of Type II were observed in Korean native chickens. The effects of the genotype on 150 days body weight trait were investigated by the associations of CC and Mm genotypes (P<0.05) in Korean native chickens. This result suggests that a significant association exists between the SNP and 150 days body weight.

Yongchonppong is liable to withering of leaf and it is lowering leaf value for the feed. In this respect, covering of the vinylon gauze over the feed has been carried out in the branch rearing system to sustain leaf value as itself. The covering of the vintlon gauze over Yongchonppong marks 7% and 9% increment of cocoon yield in dry season, spring rearing season, as compared to the non-covering of the vinylon gauze over Kaeryangppong and Yongchonppong, respectively. There was no significant differences in cocoon shell percentages of them. In more humid environment than average relative humidity in Korea the rearing results of "Yongchonppong" was improved by covering with vinylon gauze after feeding compared with the non-covered rearing. However, the vinylon guage covering was not effective for improving the rearing results of "Kaeryangppong". No effect of the vinylon gauze covering was seen in the area where it frequently rains and raining season lasts. In case of the non-covering of the vinylon gauze, Yongchonppong reduces repidly in the first three hours of exposure to the air, as compared to Kaeryangppong. The water content reductions rate of Yongchonppong in 6 hours of exposure to the air marks 7% to so when the dry vinylon gauze cover and 17 to 26% when the wet vinylon gauze covers, as compared to 58.8% of it for the noncovering of the vinylon gauze.f the vinylon gauze.

Chickens are exposed to the external and internal stressors such as low and high temperature, high stocking density, feed restriction and disease. There have been a few studies on gene expressions through the investigation of chickens under direct exposure to the stress of high stocking density. The objective of the present study was to determine the expressions of genes associated with stress, endoplasmic reticulum (ER)-stress, lipid and glucose metabolism in two strains of chickens, Korean Native Chicken (KNC) and White Leghorn (WL), raised in high stocking density. A total of 164 chickens aged 40 weeks were randomly allotted to a $540cm^2/bird$ stocking density (control), whereas the chickens in a high density group were assigned in a $311cm^2/bird$ stocking density with feeding ad libitum for 10 weeks. Total RNA was extracted from the live for qRT-PCR. The expression levels of hsp70 and $hsp90{\alpha}$ were higher in WL subjected to stress with high stocking density compared with those genes in control (P<0.05), while the expressions of genes were not affected in KNC. ER stress marker gene XBP1 was also highly expressed in WL with stress (P<0.05), but the stress of high stocking density did not influence to ER stress marker genes in KNC. Lipid metabolism associated genes including FABP4, FATP1 and ACSL1 were highly expressed in WL compared with KNC when subjected to high stocking density stress (P<0.05). The expression of glucose transport gene GLUT2 and GLUT8 were increased in chickens exposured to the stress of high stocking density (P<0.05). The data indicate that WL is more sensitive to the stress of high stocking density compared with KNC and the stress may influence the modulation of lipid and glucose metabolism in the liver of chickens.

I. 서론 : 식생활은 인간의 가장 원초적인 욕구이며 생존을 위한 기본조건입니다. 그러므로 식생활의 기본이 되는 식품은 사람에게 가식성, 영양성, 안전성을 충족시켜야 하며 여기에 생산자의 입장에서는 높은 생산성이 요구되고 있습니다. 이러한 식품의 구비조건은 과거 자급자족의 농경시대에는 생산자가 바로 소비자로서 커다란 문제를 제기하지 않았으나 도시화, 산업화된 현대사회에서는 생산자와 소비자가 다르며 식품은 상품으로서 판매되므로 소비자는 고품질의 안전한 식품을 요구하고 생산자는 수익성이 높은 고생산성의 식품을 상품으로서 생산하기에 이르렀습니다. 축산식품이 상품으로 생산되면서 생산자들은 더 높은 생산성을 요구하게 되었고 이러한 요구에 따라 축산분야에서는 가축 품종의 육종 개량과 함께 생산성을 저해하는 각종 질병의 예방과 치료약제 및 성장촉진과 사료효율을 개산할 수 있는 물질들을 사료첨가제로 개발하여 사용하게 되었습니다. 그러나 이러나 의도적으로 사용한 물질들은 대부분 항생제물질이나 화학적 합성품들로서 가축자체는 물론 생산물에 잔류되어 그 축산물을 이용하는 사람에게 유해작용의 우려를 갖게 하였습니다(의도적 오염). 또한 농작물의 생산성을 높이기 위하여 사용되는 농약들은 경우에 따라서는 샤료곡물에 잔류되어 사료를 통한 오염원ㅇ니이 될 수도 있고 목초지에 산포한 잔류성 농약이 목초를 오염시켜 뜻하지 않게 가축과 축산물을 오염시킬 수도 있습니다. 축산분야에서 잘 알려진 아플라톡신 같은 곰팡이 독소류는 오염된 사료원료에 의하여 가축에 피해를 일으킬 수 있으며 또 우유나 축산물을 통하여 사람에 피해를 줄 수 있습니다. 과학기술의 발달은 많은 공해요인들을 유발시켰으며 산업체에서 요구하는 고순도의 중금속류(수은, 납, 카드뮴 등)는 각종의 과학기계를 제작하는데 필수소재로써 우리의 생활을 윤택하게 하였지만 그 폐기물들은 우리의 생활주변을 오염시켜 그 환경에서 자라는 식물과 동물을 오염시키고 사람의 생활환경도 위태롭게 하고 있습니다.

We performed a molecular marker-based analysis of quantitative trait loci (QTLs) for traits that determine the quality of the appearance of grains, using 120 doubled-haploid (DH) lines developed by another culture from the F1 cross between ‘Cheongcheong’ (Oryza sativa L. ssp. Indica) and ‘Nagdong’ (Oryza sativa L. ssp. Japonica). The traits studied included length, width, and thickness of the grains, as well as length-to-width ratio and 1,000-grain weight. The objective of this study was to determine the genetic control of these traits in order to formulate a strategy for improving the appearance of this hybrid. Within the DH population, five traits exhibited wide variation, with mean values occurring within the range of the two parents. Three QTLs were identified for grain length on chromosomes 2, 5, and 7. Three QTLs were mapped for grain width on chromosome 2: qGW2-1, qGW2-2, and qGW2-3. Six chromosomes were identified for the grain length-to-width ratio; four of these were on chromosome 2, whereas the other two were on chromosomes 7 and 12. One QTL influencing 1,000-grain weight was identified and located on chromosome 8. The results presented in the present study should facilitate rice-breeding, especially for improved hybrid-rice quality.

This study was conducted to investigate tissue nutrient contents and salt accumulation in plastic house soils cultivating lily, rose and carnation. The soil tested had high total salts, available phosphate and exchangeable potassium. The soil cultivating rose had highest salt concentvation followed by chose of carnation and lily. Tissue nutrient contents of lily were higher than chose of carnation and rose. In comparison among cultivars, the nutrient contents were as follows; 'Snow Qeen'>'Le Reve'>'Casa Blanca' in lily; 'Marina'>'Super star'>'Mary Devor'>'Madelon' in carnation; and 'Cocktail'> 'Marina'>'Maderon' in rose. The range of the nutrient contents were: T-N: $1.66\;{\sim}2.35%$, K: $1.73{\sim}2.23%$, Zn: $2.13{\sim}6.43\;mg/kg$, Cu: $3.79{\sim}13.89\;mg/kg$ in carnation; T-N: $0.79{\sim}1.65%$, P: $0.18{\sim}0.44%$, Ca: $0.59{\sim}1.26%$, Mg: $0.21{\sim}0.46%$, Zn: $23.65{\sim}90.30\;mg/kg$, Cu: $0.99{\sim}4.62\;mg/kg$ in lily; and T-N: $0.75{\sim}1.62%$, P: $0.17{\sim}0.30%$, K: $1.60{\sim}2.91%$, Ca: $0.64{\sim}0.94%$, Zn: $24.57{\sim}48.31\;mg/kg$, Cu: $3.10{\sim}9.08\;mg/kg$ in rose. The amount of nutrients uptake per plant was high in order of: K > T-N > Ca > Mg in lily; and T-N > K > Ca > P > Mg in rose.

As a preliminary study for developing cooking techniques to improve cooked rice flavor, we surveyed consumer perceptions on purchasing rice and the consumption of cooked rice. The quantity of rice purchased by consumers was in the range of $1O{\sim}20$ kg. The purchase criterion for 50% of the subjects was the taste of the cooked rice, and half of the subjects bought their rice at a supermarket. A majority (90%) of the subjects consumed the rice within 1 to 4 months, storing it raw in the package (32.4%) or in a container at room temperature. The rice was cooked for 2 to 5 persons (65%), 1 to 2 times a day (70%) with a pressure cooker (76%). The rice and water volume were measured by eye. The cooked rice was eaten immediately (41.8%) or in 1 to 2 days (48.6%) by keeping it in an electric cooker (63.6%). The subjects perceived the rice cultivar (37.9%) as the major factor for the cooked rice flavor, as well as the region of origin (21.3%), and storage period (11.9%); the cultivars of Ilmi, Ilpoom and Chuchung were preferred. In conclusion, the consumers regard rice as a principal food; however, the methods to measure rice and water are not standardized. To improve the taste of cooked rice, consumers depend on cooking equipment and the rice cultivar.
