This study was conducted to estimate the effect of dietary alfalfa meal on the contents of egg yolk cholesterol, the levels of egg yolk pigmentation and the performance of laying hens. Alfalfa meal which was alternated wheat bran was supplied 0, 3.5 and 7%, respectively. Total 192 brown laying pullets of 47 weeks old were randomly assigned to the wire cages from July 23 to October 7, 1991 for 10 weeks. The results obtained were summarized as follows : 1. The egg production was highest at 3.5% alfalfa meal level during the entire period. But there was no significant difference among treatments. 2. Egg weight increased in treatments 3.5 and 7% alfalfa meal supplementation significantly. (P<0.01). 3. Even though there was no significant difference, the daily egg mass was the highest at 3.5% of alfalfa meal level. 4. Daily feed intake was the highest at 3.5% of alfalfa meal level. However, feed conversion rate was the lowest among treatments. 5. The feed cost per kg egg mass in the treatment of 3.5% alfalfa meal was significantly lower than the other treatments. (P<0.05). 6. Shell thickness and shell weight in terms of egg shell quality were increased as the levels of alfalfa meal were increased. But there was no significant difference among treatments. 7, The egg yolk Pigmentation was improved significantly as the level of alfalfa meal was increased (P<0.01). 8.899 yolk cholesterol contents were decreased in the treatments of 3.5 and 7% alfalfa meal supplementation compared with those in the treatment of wheat bran only(P >0.05). The results of this study indicate that 3.5% alfalfa meal level was most effective and economical in laying hen.

57 hot spring areas exist in Korea and 20 areas exist in South Korea. Of this, YUSUNG hot spring is situated in YUSUNG-KU, TAEJON city, and holds a capacity of 24 million tons, and now uses 3.11 million tons allowed of safe yield of 3.90 million tons. Temperature of YUSUNG spring water is 42~55℃, Mostly 44℃ hot waters well up from 285 meters under ground which is granite layer, but rarely 65℃ high temperature waters well up from 600 meters under ground. Acidity of YUSUNG spring waters is alkaline with pH 8.4. YUSUNG spring is a simple spring and a radium spring which is containing minerals such as iron, calcium, and sulfur. Water quality is colorless, tasteless and odorless, and is good for gastroenteric disorder, arthritis, neuralgia, diabetes and skin beauty. YUSUNG spring is convenient for transportation, and therefore number of bathing customers keep the first rank all over the country as 5,840 thousand domestic customers and 236 thousand foreign customers on yearly average. Sightseeing incomes are 4,717 won for domestic and 13,872 won for foreign per person on average and has many rooms for improvement. Japanese consider hot spring bath as hot spring cure which is regarded as a mysterious belief, and so hot spring is preserved and is used habitually. But most of Korea don't consider hot spring as a mysterious spring. Therefore hot spring is simply considered as hot waters welled up from underground. We think that YUSUNG was designated as a Sightseeing Special Area because hot spring exists in YUSUNG. But in YUSUNG are there various sightseeing resources such as the Research Complex, the EXPO Science park, the National Science Museum, five four-year universities(two universities being moved). And in the neighborhood are there the 3rd Unified Government Building, the KYERYUNG Mountain, the BAKJE Culture Belt, the DAECHUNG Dam(Korean unique dam mixed with soil and concrete), the Country Club, and the Army, Navy, and Air Force Headquaters. When spring culture is intermixed with research culture, technology culture, college culture, viewing culture, administrative culture, military culture, and sightseeing culture, the YUSUNG culture will be developed to the culture of cosmopolitan cities. It is clearly reminded that corrupted culture be removed and kindness be used to be commodities like courteous people. Fortunately, the YUSUNG Culture Center began to spread out this motion. As a private organization takes the initiative to find out the YUSUNG culture, and makes the YUSUNG culture invaluable, the YUSUNG Special Sightseeing Area will be up to the reputation.

This study shows the effect of inventory policy change from supplier-based to customer-based. We focus on the service level, cost, and information distortion of the Military Supply Chain(MSC) with System Dynamics. We design MSC model according to field practician interviews by using Vensim. The simulation makes a comparison between supply-based inventory policy performances and order-based inventory policy performances. In order to evaluate the MSC performances, we measure the accumulation of backlog(service level), supply chain cost, and order percentage overshoot(information distortion). The results show that 1) changing inventory policy from supplier-based to end customer order-based gets a good customer service, reduces MSC cost, and prevents information distortion, 2) changing inventory policy from supplier-based to immediate customer order-based reduces a small amount of MSC cost and deteriorates customer service, and 3) supply level is main factor for MSC performances improvement. This study implicates the policy change makes a improvement of MSC performance without introducing information system.

Effects of Onion Extracts on Growth Performance, Carcass Characteristics and Blood Profiles of White Mini Broilers

안병기,J.Y. Kim,S.T. Oh,강창원,S. Cho,김수기 아세아·태평양축산학회 2015 Animal Bioscience Vol.28 No.2

This experiment was carried out to investigate effects of onion extract on growth performance, meat quality and blood profiles of White mini broilers. Total of 600 one-d-old male White mini broiler chicks were divided into four groups and fed control diets (non-medicated commercial diet or antibiotics medicated) or experimental diets (non-medicated diets containing 0.3% or 0.5% onion extract) for 5 wks. The final body weight (BW) and weight gain of the group fed non-medicated control diet were lower than those of medicated control group (p<0.01). The chicks fed diet with 0.3% or 0.5% onion extract showed a similar BW to that of medicated control group. The relative weight of various organs, such as liver, spleen, bursa of Fabricius, abdominal fat, and the activities of serum enzymes were not affected by dietary treatments. There were no significant differences in meat color among groups. Whereas, groups fed diets containing onion extract had slightly lower cooking loss and higher shear force value, but not significantly. The concentrations of serum free cholesterol and triacylglycerol in groups fed diet containing onion extract were significantly decreased compared with those of controls (p<0.01). In conclusion, the onion extracts exerted a growth-promoting effect when added in White mini broiler diets, reflecting potential alternative substances to replace antibiotics.

${\omega}$-3 및 ${\omega}$-6계 지방산 첨가 사료의 급여가 어린 병아리에서 면역기관 내 지방산 조성에 미치는 영향

Effects of various combinations of corn oil (CO) and perilla oil (PO) as respective dietary sources of ${\omega}$-6 and ${\omega}$-3 polyunsaturated fatty acids on fatty acid profiles of immune organs were studied in young chicks. Seventy-five 1-day-old male (ISA Brown) chicks were assigned to five treatments with three replications. Semi-purified-type diets containing glucose and soybean meal as major ingredients were added with 8% CO, 6% CO+2% PO, 4% CO+4% PO, 2% CO+6% PO and 8% PO and fed for 7 weeks. There were no significant differences in body weight gain, feed intake and relative weights of liver and immune organs (g/100g weight) among dietary groups. Dietary fatty acid patterns were generally reflected in the fatty acid compositions of all immune organs such as spleen, thymus and bursa of Fabricius. The levels of a-linolenic acid(LNA), eicosapentaenoic acid (EPA) and docosahexaenoic acid in various immune organs increased with increasing levels of perilla oil in the diets, whilet the levels of linoleic acid (LA) and arachidonic acid (AA) decreased. Thymus appeared to have capacity to retain remarkably higher (P<0.05) levels of LA and LNA up to 37 and 22%, respectively, compared to the other organs. Thymic tissue contained ${\omega}$-3 fatty acid and ${\omega}$-6 fatty acid 10~36 times and 3~5 times higher than the other organs, respectively. Spleen tissue was specifically higher (P<0.05) in the levels of AA and EPA and the ratios of AA/LA and EPA/LNA, compared to the other organs, suggesting that the tissue might have high desaturase activity to convert LA or LNA to AA or EPA, respectively. BSA antibody production tended to increase by 18 ~ 32% with higher levels of perilla oil in diet, although the increase was not statistically significant. In conclusion, fatty acid compositions of immune organs very depending on the lipid composition of the diets and each organ appears to respond differently for its fatty acid profile to dietary lipids. Considering AA and EPA are precursors of many important eicosanoids, further studies are required to clarify the responses of the immune organs to the dietary fatty acids.

폐렴을 가진 암환자에서 사망률 예측지표 개발 및 PSI와 CURB-65의 유용성 평가

안병기,이윤선,김윤정 대한응급의학회 2015 대한응급의학회 학술대회초록집 Vol.2015 No.2

Introduction: 폐렴 환자의 사망률 예측을 위해 PSI (Pneumonia Severity Index)와 CURB-65 모델이 많이 이용되고 있으나, 암환자 폐렴에서 이러한 예측모델의 정확성에 대해서는 잘 알려져 있지 않다. 따라서, 본 연구에서는 폐렴을 가진 암환자에서 단기사망률 예측에 대한 PSI와 CURB-65의 유용성을 평가하고, 새로운 예후 예측지표를 개발하고 자 하였다. Material & Methods: 2014년 7월부터 12월까지 일개대학병원 응급실을 통해 내원한 폐렴을 가진 성인 암환자를 대상으로 후향적 코호트연구를 시행하였다. 로지스틱 회귀분석을 이용하여 28일 단기사망률 예측인자를 분석하였고, ROC곡선을 이용하여 각 예측모델의 유용성을 비교하였다. Results: 총 218명의 암환자가 포함되었고, 폐렴으로 인한 28일 단기사망률은 19.3% (42명)였다. 단기사망률과 연관된 인자는 내원 시 ECOG PS (performance status) III [OR 8.54, 95% CI (confidence interval): 3.42-21.33]과 IV [OR 13.17, 95% CI: 3.19-54.32], lactic acid [OR 1.42, 95% CI: 1.12-1.81], 초기 산소포화도[OR 3.06, 95%CI: 1.17-8.00]였고, 유의한 지표들을 병합한 새로운 예측모델의 28일 단기사망률에 대한 AUC (Area Under Curve)가 0.842 (95% CI: 0.775-0.908)였다. 반면, PSI와 CURB-65는 28일 사망률에 대해서 AUC가 각각 0.586 (95% CI:0.485-0.688)와 0.673 (95% CI: 0.584-0.762)였다. Conclusion: 폐렴을 가진 암환자에서 단기사망률은 ECOG PS, lactic acid, 초기 산소포화도와 유의하게 연관되어 있고, 이 세가지 인자들을 병합한 새로운 예측모델이 단기사망률 예측에 있어 PSI와 CURB-65보다 더 유용한 것으로 나타났다.
