이 연구의 목적은 우리나라 농업인의 평생학습체계 구축을 위한 농촌진흥기관의 역할을 정립하고, 한국농업대학의 농업인대학 운영 본부화 방안을 수립하는데 있다. 이를 위해 관련 문헌고찰, 농업인 및 농촌진흥기관의 농업인 교육 담당자들의 인식 및 요구분석, 전문가 자문 및 협의회 등의 방법을 활용하였으며, 이를 토대로 도출된 연구의 결과를 제시하면 다음과 같다. 첫째, 농촌진흥기관의 농업인교육관련 연계를 위해서는 한국농업대학이 농업인평생교육기관으로 평가인정을 받고, 전국의 농업인대학을 총체적으로 지원하는 역할을 수행하는 것이 바람직하다. 이때 지역의 농업기술센터는 한국농업대학과 협력적 관계를 구축하여 학점은행제 운영에 소요되는 교육 및 이력관리를 지원하는 역할을 수행하는 것이 필요하다. 둘째, 한국농업대학의 농업인대학 운영본부화를 위하여 평생학습원의 조직이 추가되는 것이 바람직하다. 이에 따라 평생학습원의 비전, 미션 및 전략이 제시되었으며, 조직의 기능 및 세부과제가 제시되었다. 셋째, 농업인교육의 학점은행제를 도입을 위한 체계를 설정한 후, 농업관련 기존 표준교육과정 분석, 농업인 요구분석, 전국 농업인대학 교육과정 분석, 기존 농업관련 전공 교육과정 분석, 전문가 검토 등의 과정을 거쳐서 '영농 전문학사'와 '농업 경영 학사'의 표준교육과정을 개발하였다. 넷째, 고졸미만 농업인을 위한 사전학습제도화를 위하여 농업인교육의 평가인정을 통한 방안과 One-Stop 평생학습모델을 통한 방안을 제시하였다. The purposes of this research were to assign the role of rural development organizations, and to establish the strategy for the making headquarter of farmer's university. The study was performed as follows: (1) analyzing the related literatures, documents, records review, (2) need analysis of farmers and members ig rural development organizations in terms of farmer's lifelong learning, (3) consulting experts. The following four findings are the results of this study: (1) Korean national agricultural college should be headquarter of farmer's universities and be approve for lifelong learning credit. Also, agricultural technology & extension centers should run educational program for the lifelong learning credit. (2) For the doing role of headquarter of farmer's university, division of lifelong learning should be add to department of technology training in Korea agricultural college. In relation with this, vision, mission and strategy of division of lifelong learning were suggested. (3) Steps for introduction of credit bank system of farmer education were suggested. Also standard curriculums of 'farming associate degree' and 'agricultural management bachelor's degree' were developed through analyzing existing standard curriculum related with agriculture, analyzing need of farmer, analyzing curriculum of farmer's university, analyzing curriculum of agriculture major. (4) For farmer who do not have high school graduate, two solutions were suggested which are approving farmer's education and one-stop lifelong learning model.

게르마늄의 약리효능이 알려짐에 따라 게르마늄이 깅화된 기능성 농산물의 요구도가 높아지는 추세이다. 본 연구는 게르마늄의 농업적 이용에 대한 기초 사료를 제공하고자 실시하였으며, 벼의 생육 및 게르마늄 흡수에 미치는 게르마늄처리 효과는 다음과 같다. 게르마늄을 0, 2.5, 5.0, 7.5 및 10.0 mg/kg으로 처리할 토양을 와그너포트에 넣어 벼를 재배힌 결과, 게르마늄 처리농도가 증가할수록 게르마늄 독성의 증가로 초장, 수장, 수수 및 수량이 급격히 감소하였으며 게르마늄 2.5 mg/kg 이상에서는 게르마늄 독성이 발생하였다. 게르마늄 처리농도가 증가할수록 벼의 게르마늄 흡수랑은 증가하였으나 벼의 게르마늄 이용율은 게르마늄 2.5, 5.0, 7.5 mg/kg 처리에서 각각 20.7, 12.5 및 7.5%로서 게르마늄 처리농도가 증가할수록 감소하였다. 벼의 부위별 게르마늄 함량은 볏짚>왕겨>현미 순으로 높았다. 게르마늄 2.5 mg/kg 처리시 볏짚, 왕겨 및 현미의 게르마늄 함량은 각각 103.4, 30.2 및 3.02 mg/kg 이었고, 볏짚과 왕겨에서는 게르마늄 무처리에서도 각각 2.9 및 3.9 mg/kg을 함유하고 있었다. 쌀의 아미노산 함량을 분석한 결과 게르마늄 처리농도가 증가할수록 Asx., Thr., Ser. 등 대부분 종류의 아미노산 함량이 증가하였으며, 그 결과 현미중 질소흡수량도 증가하였다. In order to obtain the basic information for agricultural utilization of Germanium(Ge), the growth characteristics and Ge absorption of rice plant were investigated with different Ge concentration in soil. Ge concentrations were treated with 0, 2.5, 5.0 7.5 and 10.0 mg/kg in pot(1/5,000a), respectively. As higher the Ge concentration in soil, the Ge absorption amount in straw, husk and brown rice were increased. But the yields were decreased with the increase of Ge phytotoxicity. When rice plant was grown more than 2.5 mg/kg Ge(as GeO₂) in the soil, growth was inhibited by germanium phytotoxicity and necrosis spots were observed in the rice leaf blades. Therefore the optimum concentration of Ge was less than 2.5 mg/kg in rice plant. When rice plant was cultivated on soil supplemented with 2.5 mg/kg Ge, Ge content in straw, husk and brown rice was 103.4, 30.2 and 3.02 mg/kg, respectively. The Ge content in plant was high in the order of straw > husk > brown rice. Most of the amino acids in rice were increased with the increase of Ge treatment, besides, total amino acid contents also increased.

Although it is well known that cancer patients suffer from malnutrition, there are few published studies on malnutrition in outpatients receiving chemotherapy in Korea. This study aimed to evaluate nutritional risk in oncology outpatients receiving chemotherapy and to show the baseline data to set up nutritional management programs for cancer patients. This is a retrospective observational analysis on 1,962 patients referred for nutritional education before or during chemotherapy at Seoul National University Hospital Cancer Center from January 2006 to May 2007. According to a malnutrition screening tool, the proportion of patients having malnutrition risk was 23.0%. In the case of upper gastrointestinal cancer, more than 50% of patients were assessed as being at the risk of malnutrition. They showed more than 7% weight loss compared to their usual body weight and poor oral intake; energy intake was less than 100% of Basal Energy Expenditure (BEE) and protein intake was less than or equal to 0.77 g/㎏/d. However, only 6.3% of breast cancer patients had risk of malnutrition and their oral intake was better; energy intake was 121% of BEE, and protein intake was 0.90 g/㎏/d. Outpatients receiving chemotherapy had different nutritional risk depending on their cancer site. Nutritional management program should be conducted differently, depending on the cancer site and upper gastrointestinal cancer patients at high risk of malnutrition should basically have nutritional assessment and intervention.

Heo, Sung-Koun,Cho, Young-Seok,Han, Sang-Dae,Chang, Jin-Kang,Yoon, Eun-Ju,Ko, Dae-Woong,Lim, Chang-Baeg,Chung, Suk-Jae,Shim, Chang-Koo,Kim, Dae-Duk The Korean Society of Pharmaceutical Sciences and 2005 Journal of Pharmaceutical Investigation Vol.35 No.5
HPMC-based novel gel formulations for the transdermal delivery of testosterone (TS) were developed, and the effect of various skin permeation enhancers was studied in vitro and in vivo. In vitro hairless mouse skin permeation of TS from the gel was investigated using Keshary-Chien diffusion cells for 8 hours at $37^{\circ}C$. In vivo plasma concentration profiles of TS after applying the gel on the abdominal skin of rat were determined using a commercial radioimmunoassay kit. Hairless mouse skin permeation of TS increased with the addition of permeation enhancers both in vitro and in vivo. Combination of diethanolamine (2%) and N-methylpyrrolidone (NMP, 6%) was the most effective among tested. Plasma concentration of TS significantly increased for at least 24 hours with the addition of diethanolamine and NMP. These results suggest the feasibility of the development of a HPMC-based gel formulation for the transdermal delivery of TS.
