The purpose of this study is to provide information searching for health promotion, nutrition improvement, and health care of the impaired elderly by ADL(Activity of Daily Living) and IADL(Instrumental Activity of Daily Living). The subjects were divided into the Assistant Needed Group and No Assistant Needed Group for living in line with the responses of ADL(10 items like dressing, washing, move etc.) and IADL(10 items like housekeeping, using transportation, shopping, Phone call etc.). Survey was made for health behavior, health risk habit, dietary management status and diet intake by 24 hr-recall and questionnaire method. 242 subjects were collected in 12 cities or Gun districts in Gyeonggi Province, S. Korea. Survey was carried out by regional home extension workers using interview method. Statistical analyses were made using SAS (Version 8.1). Chi-Square Tests and General Linear Models. The subjects of impaired ADL elderly was 26.5% and it composed 30% of the total male and 22.2% of the total female. The demographic status of the impaired ADL elderly showed no difference from that of the normal elders, elementary school educated (73.4%), with spouse (43.8%) or with adult children(37.5%), using monthly living cost of 500-1,000 thousand won(35.9%). Mean age was 74.05 years compared to 72.25 years of normal elders. However, there was no significant difference from the normal and impaired ADL group, regular exercise(60.0%), with walking (90.0%), no-smoke(54.7%) and no-drink(48.4%). Kind of disease was not different from the one in impaired and normal group, with cardiovascular disease(32.3%), with diabetes mellitus(8.1%), joint lumbago neuralgia(32.3%) and osteoporosis(9.7%). Gastrointestinal complaints of the impaired ADL group were nausea(57.8%), chronic indigestion (23.4%), constipation (14,0%) and vomiting(3.7%). Sleeping time required for the impaired was longer than that for the normal group by 10hours(4.7%) or 8-10hours(20.3%), which consisted 1.7% and 16.6% respectively. Nutrient intake of the impaired ADL group was low compared to normal range elders: Energy(1260kca1), Protein(52.75g). There was gender difference in nutrient intake; the male impaired group showed no significant difference from the normal group but it was significantly lower in female impaired group. These results suggest that low quality of life and low economic status of the impaired ADL elderly require congregate meal in village hall to cover the lack of side dishe variety. And nutrition education program including community assistance would be required for the impaired ADL elderly together with the sufficient food and exercise practice. By operating nutrition education program, the impaired ADL elderly would maintain more enhanced quality of life and ameliorate the ADL capability.

This study was carried out to investigate the effect of eating behavior, physical status and tendency of eating disorder on the right eating habit. The subjects of this study were 324 middle school students and 340 high school students in Osan city GyeongGi province. The average of weight and height in the middle and high school students were 48.7kg, 160.0cm and 56.8kg, 164.8cm respectively. In PIBW values, 92.9% of middle school students and 99.1% of high school students were almost close to the average. The 28.5% of high school and 21.5% of middle school students were aware of themselves as overweight. The risk of eating disorders in high school students(16.4%) were higher than that in middle school students(4.9%). Moreover, the risk of eating disorders in girls high school students(19.3%) was significantly higher than those of middle school students(5.2%) (p<0.001). The thought of food problems were realized in 57.4% of in high school students and in 39.9% of in middle school students. The intake of food group frequency, middle school students ate more fruit than high school students(p<0.01). Boys ate more frequently soy beans (p<0.05) and algae(p<0.1) than girls in high school students. The meat intake was more frequent in high school students, but the eggs and milk were more in middle school students. The boys' intakes of fish and milk were more often than the girls' in high school students. Eating disorders and food intake frequency scores were closely correlated with weights(PIBW and the gap of ideal. weight with real weight). In conclusion, the education about realizing exact healthy body shape and how to modify behavior to prevent eating disorders should be planned since junior high school. Especially in high school girls, the variety food intake education would be needed. Proper recognition of the weight is required for good food intake and for prevent eating disorders.

The purpose of this study is to provide the information of the aged olds for which basic data are almost no available. The subjects were divided on the base of age 75. The elderly under 75 were named 'the young olds' and over 75 were 'the aged olds'. The aim of this research is to promote health and to improve nutrition, and the survey was made for health promotion behaviors, habits against health risk, dietary management status and diet intake. And it was conducted by 24 hr-recall method and analyzed by nutrients intake. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire about health behavior and dietary management was carried out by interview method through regional home extension workers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Out of the subjects the aged olds over 75 was 31.9%, elementary school educated (93.5%), with spouse (40.3%), with adult children(28.6%), monthly living cost of 500-1,000 thousand won(40.3%). Mean age was 78.82 years compared with 69.75 years of the young olds. 46.8% of the aged olds used monthly pocket money over 1000 won and it was lower than 63.3% of the young olds. Only half of the aged olds had regular exercise of walking (77.8%) or with athletic equipment (17.8%). However, the young olds did more frequent walking (82.1 %) and less exercise with athletic equipment (4.8 %), which was significantly different. Kinds of disease were different with the young or the aged olds, as more proportion of cardiovascular disease(37.9%) for the young olds and joint lumbago neuralgia(41.6%) for the aged olds. Dietary management was good (3 meals per day: 93.4%, fixed mealtime: 72.4%, and regular amount: 79.9%). But there was significant difference in side dish varieties and kinds of snacks; for the aged olds only 8% had over 5 sorts (compared with 18.8% of the young olds) and the kinds of snacks were cookie, candy, juice, carbonated beverage for the aged olds (compared with noodle, milk, soybean-milk for young olds). The ratio of nutrients intake (energy, riboflavin and niacin) with RDA was significantly higher for the aged olds than that of the young olds. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some of the aged olds had difficulties in Instrumental Activities of Daily Living (IADL) like housekeeping, using transportation, going shopping and making phone calls. These results suggest that low quality of life is linked with low economic status of the rural elderly and congregate meal at village hall would be required because of the lack of side dishes variety for the aged olds. And nutrition education program about good snacks and exercise practice would be needed for the aged olds. By operating nutrition education program the aged olds would enjoy better quality life maintaining or ameliorating IADL abilities.

Although national and regional environmentally friend agriculture (EFA) and food development programmes such as the Life-Food Development Plan (LFDP) have been established in Korea, some policy measures in these programmes seem to be unsuitable for Korean organic farming development. Policy measures tend to support external input purchases of organic fertilizers rather than market development actions such as providing consumer information, research, education, training and statistical data collection. The development of an organic action plan (OAP) for Korea is therefore considered essential for the sustainable future of organic farming in Korea. The purposes of OAP are 1) to define and set the clear goals/targets for the organic sector development, 2) to integrate various organic stakeholders and public institutions in partnership, 3)to focus on specific issues with tailored measures and 4) to integrate and develop different policy measures (Stolze, 2005). Most EU member state countries have developed their own OAPs and each reflects its own priorities with regard to organic sector development. This study compares and contrasts the Welsh, England and EU OAP with the Korean Jeonnam Life-Food Development Plan (LFDP) in order to facilitate the development of the organic food and farming sector in Korea. Early action plan, for example, the first Welsh OAP(1999) focused support on developing the supply of organic products whereas later action plans (e.g. England OAPs in 2002 and 2004 and the second Welsh OAP in 2005) focussed more on developing consumer demands for organic products. The EU OAP (2004) also aims at market support related to consumer demand and then organic farming production for its environmental and other social benefits. OAPs not only provide specific issue-solving tools but also perform a role as providing a focus for organic sector development as a whole. The Korean LFDP provides issue-solving tools but plays no regulatory role such as policy development, harmonizing various policy measures and conflicting factors and providing evaluation tools for further development. A national-level OAP could also facilitate international trade of organic products. To achieve better harmonized and sustainable approaches for the Korean organic industry, National- as well as regional- regulatory policy systems are urgently required in the form of an Organic Action Plan.

Growth and yield of licorice were investigated under the different conditions of ridge height, planting density, and irrigation in order to establish its cultural practices for the domestic production with the aim to substitute the import. Seedlings were grown under low ridge(20cm) and high ridge(40cm) in low density plot(60$\times$30cm) and high density plot(40$\times$30cm), respectively. The low ridge cultivation of large seedlings increased plant height and root length under low density, and stem and root diameter under high density compared to the high ridge cultivation. In the high ridge cultivation, high density plot was 1.1 to 1.3 times in plant height, root length, stem and root diameter as high as low density one. Fresh and dry weight of plant and root in high ridge were 1.3 to 1.5 times as high as those in low one. The growth of small seedlings(4~10g) were generally poor compared to that of large seedlings. High density plot in low ridge showed the good growth characteristics including plant height, root length, stem and root diameter, and number of branch. High density plot was 1.4 to 1.6 times in fresh and dry weight of plant and root as high as low density plot. In the seasonal changes of growth under various irrigation regimes, the twice irrigation a day produced the more number of leaf than the other regimes since around 46 days after transplanting. The former irrigation resulted in 1.2 to 1.4 times in plant height as long as the other irrigations around 26 days after transplanting and then the difference was increased to 1.6 to 2.0 times around 64 days after transplanting. Under the twice irrigation a day, plant height, root length, stem diameter, root diameter, number of leaf, fresh plant weight, dry plant weight, fresh root weight, dry root weight were 1.6 to 2.0, 1.1, 1.2 to 1.6, 1.3 to 1.8, 1.9 to 2.7, 1.7 to 8.0, 1.6 to 2.8,2.0 to 3.0, 1.6 to 2.7 times as high as those under the other irrigation regimes, respectively.

본 연구의 목적은 농업후계자들이 대학에서 전문교육을 받고 귀향한 후 친환경농업을 실천하는 데 따른 어려움을 파악하고 이를 해결할 수 있는 방안을 검토하는 데 있다. 본 연구의 조사대상은 전체 한농대 졸업생 감귤농가 24명 중에서 친환경농업을 실천하고 있거나 실천 경험이 있는 총 8명 중 조사에 응한 6농가이며, 개방형 설문지에 의한 사례 연구 방식으로 분석되었다. 사례농가들의 영농실태 분석결과, 이들은 기후변화 및 시장개발에 대응하기 위해 작목전환과 경영의 다각화를 도모하고 있으며, 농법으로는 한 농가만이 무농약 수준의 친환경농업을 희망하고 있고 대부분 유기재배를 지향하고 있다. 사례농가의 경영비 분석결과, 자재비 기준으로 물재비는 더 적게 들지만 관행농업과 같은 수준의 상품성을 얻기 위해서는 노력비가 더 들어가야 하는 것으로 조사되었다. 친환경농업의 생산량은 관행농업에 비해 20-50% 정도 감소하며, 판매가격은 10-50% 높은 것으로 나타났다. 친환경 감귤농가의 애로사항으로는 유기농업 기술 부족과 친환경농업에 적합한 판로부족이며 규모확대를 위한 토지구입이 어려운 것은 제주 농업이 갖는 특수한 제약조건이다. 졸업생 농가의 친환경농법으로의 전환은 부모님과의 합의가 어려운 문제로 나타나고 있으며, 친환경농업 기술을 자문 받을 수 있는 지역의 창구가 없다는 점이 지적되었다. 졸업생농가가 친환경농법으로 전환하기 위해서는 농업기술원 및 농업기술센타를 중심으로 친환경농업 선진농가와의 연계를 통해서 지속적인 기술교육과 자문이 이루어질 수 있도록 가칭 '제주 친환경 생태 유기농업 포럼'을 구성하여 기술자문 및 현장애로 기술이 개발 보급될 필요가 있다. 친환경 감귤의 적정 가격과 판로를 확보하기 위해서는 제주 지역의 로컬푸드와 연계된 판매활동과 육지의 로컬푸드와의 연계도 필요하다. 안전성과 신선도의 가치를 소비자가 신뢰하고 구매할 수 있는 다양한 유통채널을 확보해야 한다. 대부분의 사례농가의 소득증대를 위해서 장기적으로 체험이나 관광과 연계할 수 있는 6차농업의 농장경영을 구상할 필요가 있다. 다양한 품종의 감귤을 도입하여 다양성을 확보하고 체험 및 관광과 연계시켜 생태 유기농장으로 발전해 가야 한다. 이를 위해서는 국내외 선진 농장을 벤치마킹하고 정책사업과 연계할 수 있는 기반을 조성해야 한다. 한국농수산대학에서는 제주지역 졸업생들이 친환경 유기농업을 통해서 경영의 안정을 꾀하고 지역농업의 리더가 될 수 있도록 연구기관 및 보급기관과 연계하여 제주지역에 맞는 지원 프로그램을 개발하고 이를 바탕으로 졸업 후에도 지속적으로 새로운 정보와 기술을 제공해야 한다.

Myxococcus xanthus (MX, PX)와 Arabidopsis thaliana (AP37)의 protoporphyrinogen oxidase (Protox)유전자 과다발현 제초제 저항성 형질전환 벼와 비형질전환벼의 생육 및 수량에 관한 적응성 차이와 벼생육시기별 ALA 합성능력, tetrapyrrole 중간물질, 활성산소 발생, 지질과산화 작용 및 항산화효소 능력의 연관성이 조사되었다. Protox 과다발현 형질전환 벼 MX와 AP37의 초장은 이앙 후 43, 50, 65일에 비형질전환벼 비형질전환벼에 비해 유의적으로 적었고, 분얼수는 이앙 후 50일과 65일에 MX와 AP37 뿐만 아니라 PX에서도 비형질전환벼에 비해 유의적으로 적었다. 수확기의 간장과 수량은 MX, PX 및 AP37에서 그리고 고건중은 MX와 AP37에서 비형질전환벼에 비해 유의적으로 적었다. 형질전환벼 계통 MX, PX 및 AP37의 수량감소는 MX의 경우 영화수와 천립중에 의해, PX는 등숙율에 의해, AP37은 영화수, 등숙율 및 천립중에 의해서 기인되었다. 한편, 형질전환벼 계통 MX, PX 및 AP37의 수량감소는 또 다른 년차변이 연구에서도 관찰되었다. 이러한 형질전환벼계통의 생육 감소는 이앙 후 생육기간 뿐만 아니라 이앙 전 육묘기간 동안에서도 발생하여 결과적으로 수량이 감소되는 것으로 생각된다. Tetrapyrrole 중간물질 Proto IX, Mg-Proto IX 및 Mg-Proto IX monomethyl ester의 축적량, 활성산소종($H_2O_2$와 ${O_2}^-$), MDA, 및 항산화효소(superoxide dismutase, caltalase, peroxidase, ascorbate peroxidase, glutathione reductase) 및 엽록소 함량은 Protox 유전자 과다발현형질전환벼 계통과 비형질전환벼간에 유의적인 차이가 없어 이들 porphyrin 대사 경로 물질과 벼 생육 및 수량감소의 연관성은 적은 것으로 사료된다. 그러나 MX, PX, AP37의 ALA 합성능력은 광노출 후 1일과 이앙 후 52일에 비형질전환벼에 비해 유의적으로 감소하여 이 부분에 대한 상세한 연구가 추후에 수행되어야 할 것으로 보인다.
