Wild brids are considered as a potential source of Campylobacter infection for humans and farm animals. However, there have been few investigation into the population biology of Campylobacter in wild birds, including migratory waterfowl inhabited at Korean peninsula. Consequently, whether wild birds found in korea are a source of infection in humans or domestic livestock. To address this question, after fecal sample were collected from wild birds in important migratory habitats, and the feces were tested. A total of 308 fecal samples (15.7%) from 26 wild brids species among 1,950 specimens were culture postive for Campylobacter spp. According to migratory types, the most frequent birds having Campylobacter spp were transit birds (22.5%). These isolates were further characterized by PCR. Campylobacter jejuni was the most prevalent species in all wild birds sample, followed as Campylobacter coli (21.2%) and Campylobacter lari (1.0%). The most important habitat site for isolating Campylobacter spp. was the Gap-stream located at middle part of Korea. In conclusion, wild birds cannot be excluded as a soruce of infection for humans and farm animals.

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

안병기,연제영,지규만,Ahn, Byeong-Ki,Youn, Je-Yeong,Chee, Kyu-Man 한국가금학회 2003 韓國家禽學會誌 Vol.30 No.4

본 연구에서는 ${\omega}$-6 및 ${\omega}$-3계 지방산을 함유한 유지의 첨가비율을 달리한 실험사료를 어린 병아리에서 급여했을 때 면연 기관의 지방산조성에 미치는 영향을 조사하였다. 5개의 처리구에 각 처리당 3반복을 두고 총 75수의 1일령 수평아리를 공시하였다. 옥수수유(CO)와 들깨유(PO)를 중량비로 각각 8%+0%, , 6%+2%, 4%+4%, 2%+6%, 0%+8% 수준으로 첨가한 반정제 실험 사료를 7주간 급여하였다. 실험 종료시 증체량 및 사료섭취량은 처리 간에 큰 차이가 보이지 않았으며 체중 100g당 간장 중량 및 면역 기관 중량에서도 유의한 차이가 인정되지 않았다. 면역조직 내 지방산 조성은 EPA와 AA(arachidonic acid)를 포함하여 섭취한 사료 지방산의 조성을 잘 반영하는 경향을 보였는데, 면역기관 간에 그 정도에 차이가 있었다. 들깨유의 첨가수준이 증가함에 따라 linoleie acid LA)의 비율이 점진적으로 감소하였고 반면 a-linolenic acid(LNA) 비율은 현저하게 증가하는 경향이었다. 흉선에는 .LA와 LNA의 함량이 다른 조직보다 현저히 더 많아서 섭취하는 지방산의 조성이 가장 잘 반영되었다. 비장 조직에는 HPA 및 AA 농도와 EPA/LNA, AA/LA의 비율이 다른 조직에 비해 현저히 더 높았는데 이는 비장이 LA나 LNA로부터 AA나 EPA로 전환하는 능력이 높음을 의미한다. 실험사료 급여후 2, 4주후에 조사된 anti-BSA 항체가 유의한 차이는 인정되지 않았으나 CO 8%구에 비해 PO를 첨가한 모든 구에서 더 많이 생성되는 경향이 관찰되었고 특히 PO를 6% 및 8% 첨가한 실험구에서 20~30%나 더 높아졌다. 결론적으로 섭취하는 지방산 조성에 따라 면역기관내 모든 지방산 조성이 변하였으며, 면역기관에 따라 그 반응정도가 달라지는 것이 관찰되었다. 이는 eicosanoids 합성에도 영향을 미칠 수 있기 때문에 가금에서 질병에 대한 면역력 향상이라는 관점에서 앞으로 더 세밀한 연구가 필요하다. 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.

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.

The purpose of this study was to identify the factors affecting the use of superior general hospitals on public holidays by using the medical use model (Dutton 's medical use model) with the medical panel data. The study found that 34.2% of superior general hospital emergency rooms were used on public holidays and the factors which made statistically significant influences on the use of superior general hospital emergency rooms on public holidays were whether patients were operated or emergency care and inspection etc. Also, there was a difference depending on whether the type of establishment of the medical insititution is national or private. In other words, patients who received emergency care and examinations were found to make more frequent visit to hospital emergency room on pubic holiday ,compared to patients who underwent surgery and those who visited emergency rooms in the private superior general hospital did so, compared to those who visited emergency room in the national general hospital(OR, 4.4, 3.386, respectively). Therefore, it is necessary to consider the introduction of integrated care of health and social care medical service that focuses on primary care in Denmark, which focuses on patients, and pre-The Canadian Triage and Acuity Scale(pre-CTAS) in the UK.

The Tissue Distribution of Lutein in Laying Hens Fed Lutein Fortified Chlorella and Production of Chicken Eggs Enriched with Lutein

안병기,Jin-Young Jeon,강창원,김진만,황재관 한국축산식품학회 2014 한국축산식품학회지 Vol.34 No.2

Two experiments were conducted to investigate the dietary effects of conventional or lutein fortified chlorella on luteinabsorptions, the tissue distributions and the changes in lutein content of eggs in laying hens. In Exp 1, a total of one hundredand fifty, 70 wk-old Hy-Line brown layers were divided into three groups with five replicates and fed with each experimentdiet (control diet, diet with 1% conventional chlorella or lutein fortified chlorella) for 2 wk, respectively. The egg productionin groups fed diets containing both chlorella powders were higher than that of the control group (p<0.01). With chlorellasupplementations, the yolk color significantly increased, although there were no significant differences in the eggshell qual-ities. The lutein contents of serum, liver and growing oocytes were greatly increased by feeding conventional or lutein for-tified chlorella (p<0.01). In Exp. 2, a total of ninety 60 wk-old Hy-Line brown layers were assigned into three groups withthree replicates per group (10 birds per replicate). The birds were fed with one of three experimental diets (0, 0.1 or 0.2%lutein fortified chlorella) for 2 wk, respectively. The egg production was not affected by dietary treatments. The egg weightin the group fed with diet containing 0.2% of lutein fortified chlorella was higher than that of the control (p<0.05). As thedietary chlorella levels increased, the daily egg mass linearly increased, although not significantly. The yolk colors in groupsfed diets containing lutein fortified chlorella were dramatically increased as compared to the control (p<0.001). The luteinin chicken eggs significantly increased when fed with 0.2% of lutein fortified chlorella (p<0.01). These results suggestedthat the dietary lutein derived from chlorella was readily absorbed into the serum and absorbed by the liver with growingoocyte for commercial laying hens. Particularly, the lutein fortified chlorella was a valuable natural source for the produc-tion of lutein enriched chicken eggs.

We used the 2008-2015 Korea Health Panel Data. Of the total 2,058 cases of admission, 298 cases(14.5%) of admissions are made by the decision of patients or their families with disabilities. The multiple logistic regression analysis shows that the admission decision by patients or their families with disabilities(ADPFD) is higher in the 18-44 years age group(OR:27.332) and 45-64 years of age group(OR:28.823) and 65 years old or older years of age group(OR:26.113) compared with the under 17 years age group. the ADPFD rate is higher in the patients admitted in hospital or clinics(1.980) and geriatric hospital or convalescent hospital(OR:12.785) than that of admitted in superior general hospitals. the ADPFD rate is higher in the patients admitted in 29-30 days(OR:8.108) and more than 31 days(OR:1.635) than that of admitted 13 days or less. In addition, The ADPFD rate is higher in the medical aid’s group(OR:4.499) and national merit reward beneficiaries and their family’s group(OR:3.836) compared with the National health insurance’s group. Accordingly, various health care utilization policies should be developed in order to enable disabled people who are admitted by patients with disabilities and their families to use medical services in appropriate places. 연구 결과, 총 2,058명의 입원환자 중 14.5%인 298명이 장애인 환자 및 가족 등에 의해 입원하였다. 입원한 환자들은 17세 이하의 환자보다 18-44세 환자, 45-64세 환자, 65세 이상 환자가 각각 27.332배, 28.823배, 26.113배 많았고, 의료기관 종별유형에서 상급종합병원에 입원한 환자보다 병원 및 의원과 노인 및 요양병원에 입원한 환자가 각각 1.980배, 12.785배 많았으며, 재원 기간에서 13일 이하로 입원한 환자보다 29-30일 입원한 환자와 31일 이상 입원한 환자가 각각 8.108배, 1.635배 많았고, 진료비 지급유형에서 건강보험환자보다 의료급여환자와 국가 유공자 및 가족 특례 환자가 각각 4.499배, 3.836배 많았으며, 의료기관 선택 사유에서 다니던 병원이었기 때문에 입원한 환자보다 병원이 가까우므로 입원한 환자가 1.635배 많았다. 이에 따라, 장애인 환자 및 가족 등에 의해 입원된 장애인들이 적절한 곳에서 의료이용이 되기 위해서는 다양한 보건의료 이용정책(입원기준 마련, 사전입원허가제 도입, 본인부담금 책정 일원화, 보건의료이용정보체계 개선, 덴마크와 스웨덴의 지역사회 중심의 통합의료서비스체계 구축)들이 개발되어야겠다.
