熱帶地域 또는 開發途上國에 滯留하는 先進國의 外國人 滯留者들은 肝炎感染의 높은 危險性을 지니고 있다. 日本海外協力駐在員들은 肝炎罹患率을 보면 1978年度에서 1982年度까지 20~35年齡群에서 年平均 3.6%였다. 이 罹患率은 같은 年齡群에 있는 「버마」靑年으로서 肝炎으로 入院한 admission rate보다 30培以上이 되는 셈이다. 海外駐在 美國宣敎師의 境遇도 비슷한 樣相을 띠고 있다. 肝炎罹患率은 東南亞細亞와 地中海沿岸國家에서 높았으나 오히려 「사하라」 南部의 「아프리카」地域國家에서는 낮았다. 地域沿岸國家中 Syria에서는 이 二年間 滯留中 肝炎罹患率이 31.8%로 나타나기도 하였다. 本 疫學的 硏究結果는 海外駐在員들의 肝炎豫防對策을 세움에 있어 有用한 資料가 될 것이다. Foreign sojourners from developed countries ran a high risk of hepatitis infection in tropical and/or developing countries. The incidence of hepatitis in the Japan Overseas Cooperation Volunteers, aged between 20 and 35 years, was 3.6 percent per year in 1978-1982. The incidence was more than 30 times higher than the admission rate of Burmemse youths of the same age group with hepatitis. Similar figures were obtained by the U.S. missionaries abroad. The incidence was high in Southeast Asian and peri-Mediterranean countries but was rather low in African countries south of the Sahara. The incidence of hepatitis in two years of assignment was as high as 32 percent of volunteers in some countries. some epidemiological data that would be useful for the planning of preventive measures were presented.

Current situation and future prospects for beef production in Europe - A review
Hocquette, Jean-Francois,Ellies-Oury, Marie-Pierre,Lherm, Michel,Pineau, Christele,Deblitz, Claus,Farmer, Linda Asian Australasian Association of Animal Productio 2018 Animal Bioscience Vol.31 No.7
The European Union (EU) is the world's third largest producer of beef. This contributes to the economy, rural development, social life, culture and gastronomy of Europe. The diversity of breeds, animal types (cows, bulls, steers, heifers) and farming systems (intensive, extensive on permanent or temporary pastures, mixed, breeders, feeders, etc) is a strength, and a weakness as the industry is often fragmented and poorly connected. There are also societal concerns regarding animal welfare and environmental issues, despite some positive environmental impacts of farming systems. The EU is amongst the most efficient for beef production as demonstrated by a relative low production of greenhouse gases. Due to regional differences in terms of climate, pasture availability, livestock practices and farms characteristics, productivity and incomes of beef producers vary widely across regions, being among the lowest of the agricultural systems. The beef industry is facing unprecedented challenges related to animal welfare, environmental impact, origin, authenticity, nutritional benefits and eating quality of beef. These may affect the whole industry, especially its farmers. It is therefore essential to bring the beef industry together to spread best practice and better exploit research to maintain and develop an economically viable and sustainable beef industry. Meeting consumers' expectations may be achieved by a better prediction of beef palatability using a modelling approach, such as in Australia. There is a need for accurate information and dissemination on the benefits and issues of beef for human health and for environmental impact. A better objective description of goods and services derived from livestock farming is also required. Putting into practice "agroecology" and organic farming principles are other potential avenues for the future. Different future scenarios can be written depending on the major driving forces, notably meat consumption, climate change, environmental policies and future organization of the supply chain.

A Further Generalization of Apostol-Bernoulli Polynomials and Related polynomials
( R Trem Blay ),( S Gab Oury ),( J Fug Ere ) 호남수학회 2012 호남수학학술지 Vol.34 No.3
The purpose of this paper is to introduce and investigate two new classes of generalized Bernoulli and Apostol-Bernoulli polynomials based on the de nition given recently by the authors [29]. In particular, we obtain a new addition formula for the new class of the generalized Bernoulli polynomials. We also give an ex- tension and some analogues of the Srivastava-Pinter addition theorem [28] for both classes. Finally, by making use of the new addition formula, we exhibit several interesting relationships between generalized Bernoulli polynomials and other polynomials or special functions.

This study was conducted to investigate the effects of breed and parity of recipients, grade of frozen-thawed embryos and degree of donor-recipients synchrony on conception rate when the frozen-thawed bovine embryos were transferred to 60 heads of Korean Native cattle (KNC), Holstein and crossbred in Livestock Experiment Station, Rural Development Administration, and nearby large farms. To synchronize the estrus, regularly cycling heifers and cows of 114 heads were injected with 50㎍ of cloprosternol twice 11 days apart. The results obtained from this study were summarized as follows; 1. Cows showed estrus with the range of 2-6 days after the first shot and 2.5-4 days after the second shot. The rate of response was higher in the second shot (82.5%) than the first shot (67.5%). 2. The rate of response to cloprostenol after the first shot was high in crossbred, Holstein and KNC in the order, although no significant differences were noted in the second shot. 3. The overall conception rate was 45.0% and that of Holstein was 52.2% (24/46) and that of KNC was 37.5% (3/8). However none of crossbred was pregnant. 4. The conception rate of heifers (46.9%) was slightly higher than that (42.9%) of cows. 5. The conception rate of cattle transferred with excellent, good and fair embryos were 68.9%, 35.9% and 40.9%, respectively. 6. The conception rate was highest when the recipients began to show estrus 12 hours later than donor did.
