Growth and quality of rice are affected by various factors including the location of cultivation. This study was conducted to investigate the effects of altitudinal locations on the growth and yield-related components of rice. Nineteen Japonica type varieties were grown at Iksan (altitude, 10 m), Imsil (altitude, 150 m), Jinan (altitude, 275 m) and Jangsu (altitude, 430 m) at a similar latitude in Jeonbuk province in the south western Korea. Minimum air temperature showed a strong negative correlation with altitude. The morphological traits and yield-and quality-related components were analyzed. Longer days to heading was required at higher altitudes. However, culm length, panicle length, panicle number, grain number and rice yield were reduced at higher altitudes. Protein content of brown rice increased but fatty acid content decreased at higher altitudes. Amylose content was affected by neither the altitude nor the ecotype. Palatability of polished rice tends to be improved at higher altitudes and in early-maturing ecotypes but its relationships with altitude and ecotype were not significant. Head rice ratio was lower at higher altitudes but broken rice ratio vise versa. These results indicate that growth and quality of rice are affected significantly by changes in temperatures at the locations of different altitude. Also, the characters related to yield and quality of rice often respond incompatibly to the changes in altitudes. These results could provide valuable information for the strategic planning of rice production in geographically diverse areas.

The conclusion of free Trade Agreement between South Korea and USA can become a serious threat to the Korean agriculture. On the strategic scheme the foodstuffs is the basis for protection of the state sovereignty. The Amur oblast of Russian Federation is region, which can supply South Korea cheap and good qualitative feeds. It means South Korea should create agricultural cooperation with the Amur oblast of Russian Federation with the purpose to begin organic agriculture in this area and it will help South Korea to counteract a quantitative attack on Korea from the side of american agricultural production. In the Amur oblast there are following fodder crops; Alfalfa, Smooth brome grass (gromus adonis L.), Siberian couch grass, Sudan pass, Colza rape (Brassica napus) and Amaranth (Avfranthus). In the same area also exist oatmeal, wheat, corn and barley, which is possible to use for feeds. All these above written cultures are cultivated organically, therefore it is possible to use them as organic forages in South Korea. It is very important to know system of crop rotation in the Amur oblast. There is a scheme of crop rotation, which is connected with increase and preservation of fertility of soil, maintenance of growth of productivity of agricultural cultures and reception of high-quality production. It is necessary to begin organic agriculture in a southern part of Amur oblast, where, in 2001 year, 97% of all sowing areas was concentrated. The acidity degree of soil in this part is not high ($ph5.1{\sim}5.5$), therefore does not require liming.

In responding to climate change in the agricultural sector, Climate Smart Agriculture (CSA) is an approach to establish a sustainable agricultural system through comprehensive management of technology, policy, and investment. The international community is continually expanding CSA implementation, and it became more important to understand the status of the domestic agriculture system and practices that are relevant to CSA. This study explored the available CSA in domestic agricultural systems and presented the order of relative importance of CSA technology. AHP analysis is employed for the evaluation with the following criteria: productivity, marketability, adaptability, and mitigation. The relative importance is evaluated with six agricultural technologies (soil, crop management, water, energy efficiency, alternative energy, and precision agriculture) in 28 agricultural technology sectors. The results of the AHP analysis showed that 'alternative energy' was found to be a top priority among the agricultural technology sectors, and 'shallow depth drain in rice paddy' was a top priority for agricultural technology. Also, the 'marketability' in soil and water sectors, 'mitigation' in crop management, and 'adaptability' in energy efficiency and alternative energy were given higher priority. The results of this study can be used as a good source for strategic CSA preparation and application.

Pesticides have provided significant benefits including plant disease control and increased crop yields since people developed and utilized them. However, pesticide use is associated with many adverse effects, which necessitate precise toxicological tests and risk assessment. Most of these methods are based on animal studies, but considerations of animal welfare and ethics require the development of alternative methods for the evaluation of pesticide toxicity. Although the usage of laboratory animals is inevitable in scientific evaluation and alternative approaches have limitations in the whole coverage, continuous effort is necessary to minimize animal use and to develop reliable alternative tests for pesticide evaluation. This review discusses alternative approaches for pesticide toxicity tests and hazard evaluation that have been used in peer-reviewed reports and could be applied in future studies based on the critical animal research principles of reduction, replacement, and refinement.

본고에서는 최근 중국을 중심으로 추진되고 있는 한약재 ISO 국제표준화에 대한 대응을 위해 최신 등재 현황을 소개하고 주요 추진상의 문제점과 대응방안들을 점검해 보았다. 주요 내용을 정리하면 다음과 같다. 1. 국제표준화기구 전통의학 기술위원회(ISO TC249)는 2009년 설립이후 31개의 국가가 참여하여 한약재 국제표준화를 추진하고 있다. 한 중 일은 발의 문건은 90%이상을 차지하여 사실상 아시아의 전통의학 분야를 두고 경쟁하고 있으며 간사국인 중국은 약용작물의 종자 종묘에서부터 약재의 생산, 품질 그리고 침구, 의료기술 등에 이르기까지 전 한방분야에서 표준화를 주도하고 있다. 현재 진행되고 있는 약용작물 재배 및 한약재 품질 관련 안건만 약 50여건에 달해 향후 5년 내에 시장 거래량 상위품목들의 국제표준화 작업이 대부분 완료될 것으로 예상된다. 2. 현재 진행되고 있는 안건들은 한약재의 품질이나 품질평가에 관한 안건들이 대부분이다. 이 안건들이 국제표준으로 인정되면 세계 한약재 유통시장에는 새로운 질서와 우열기준이 생기고 유통 한약재의 시장가치 평가에 반영되어 각국 한약재 점유율 변동에도 영향을 줄 수 있다. 이들 안건들은 직접적인 재배생산 표준이 아닌 경우가 대부분이지만 성분이나 성상 등에 대한 표준을 담고 있으므로 대부분 재배생산과도 밀접한 관련이 있다. 만일 중국 중심의 표준화가 계속해서 심화된다면 장기적으로는 국내 생산농가에 부담을 줄 수도 있다. 그러므로 한약재 국제표준화 대응은 향후 국내 생산물이 표준규격을 달성할 수 있는 범위내로 기준을 유도하는 전략을 펴야 할 것이다. 이를 위해 국내 생산물의 특성을 파악하고 선반영 하려는 노력이 필요하다. 3. 한약재 표준화 대응은 중국의 추진안건이 많으므로 분야별 파급영향을 고려한 선별적인 대응이 필요하다. 종자 종묘 등 추가적인 제한 필요성이 낮은 분야보다는 향후 시장에서 한 중 간 경쟁이 발생할 수 있는 분야에 집중하는 것이 중요하다. 원산지 변조, 농약 잔류량 이산화황 과다검출 등의 이력이 있는 약재들은 해당 표준을 강화하고 재배환경의 영향을 받을 수 있는 도지약재들의 경우 성상이나 지표성분 등에 대한 국내약재의 특성을 최대한 반영할 필요성이 있다. 곰팡이나 해충관리 등은 아직 각국의 관리규정이나 저온저장 시설 등 현장 인프라 구축이 충분치 않은 점들도 고려되어야 한다. 아직 국제표준을 추진하기 위한 국내의 연구결과들이 충분치 않은 부분들이 많으므로 추가적인 연구와 지원이 필요할 것이다.

A participation scheme involving smallholder dairy farmers in improving dairy productivity through the use of local feeds, on-farm established feeds and crop residues was carried out in the Northeast, Thailand. At six milk collection centers, 63 farmers with 340 lactating cows participated in this research and demonstration of feed supplements. Farmers and cows were allotted to receive respective feed supplements: high-quality feed block (HQFB), high-quality feed pellet (HQFP), dried cassava leaf/cassava hay, dried leucaena leaf and cottonseed meal: 5% urea treated rice straw was fed as a source of roughage throughout the feeding period of the dry season. Trainings and workshops were organized by the researchers at the University, research station, demonstration sites and on-farms. Regular visits to the fartns by researchers and extension officers were made while discussions and demonstrations were performed in addition. Participating farmers also visited other farmers during the demonstration which offered a real practical perspective and farmer-to-farmer interaction. As a result of this participation and demonstration scheme, the farmers could learn more effectively and accepted the technology more readily, especially the practicality of the feed preparation, feed establishment, feeding method and feed reserve. Strategic supplementation of these feed supplements resulted in improving milk yield, milk quality, overall condition of the cows and higher income return through increased productivity and lower level use of concentrate to milk yield from 1:2 to 1:3 or lower. Based on this research and demonstration /participation scheme, all feed supplements enhanced productivity, however the establishment of cassava hay on fartns deserved more attention and warrants a wider developmental expansion among dairy farmers since it contained high rumen by-pass protein (tannin-protein complex) and could be easily produced and be sustainable on farms.

The objectives of this study were to 1) classify the cooperative farmers' organizations in Korea according to the development level and institutional aspects through the exploration of its' conceptual and institutional basis, 2) analyze the farmers' needs for organization, 3) identify the problems and situation of organizations, and 4) formulate an effective management model for each cooperative farmers' organization. The study was carried out through a review of literature and using available statistical data collected from various sources and empirical survey. Major findings of the study were: 1) the cooperative farmers' organizations could be classified into four types : crop units, farming cooperative corporation, trust farming companies and joint-stock agri-business. 2) a lot of members of the organization feel that the information is insufficient, the opportunity to suggest their own ideas is hardly given, and the members are not satisfied with the cooperation among the members, 3) the members who have higher level of schooling education showed a higher participation level in the organization, 4) most of members did not recognize the organization they participated in, 5) participation of the organization's members and concerned institutions is an important factor to promote problem solving and better communication within the organization, 6) any type of continuing education for the members is needed to facilitate the transfer of a new agricultural and organizational technology, 7) research and development(R & D) is one of the most important factors of the development of organizations, 8) most organizations are deficient in professional management skills(financial, personal, accounts, etc.), 9) the trust farming companies have difficulties in managing the firm on account of the characteristics of agriculture(especially seasonal), the dispersed trust lands, and the need for more alternative work in the winter season, and 10) in the case of agri-businesses, their organizations are more specialized in marketing and have more structured systems of management. Based on the results of the study the following recommendations were made for further improvement and development of agricultural cooperative organizations : (1) More governmental support should be given to education for improvement of the organizational structure. And more deliberate and differentiated governmental support should be provided for the organizations to be viably managed. (2) For more efficient communication between the members and the organization, more opportunities for discussion are needed. (3) The more research should be committed to this kind of work in order to get more analytic data and strategic plans of cooperative organizations.

사회주의 계획경제 체제를 유지해오던 북한 내에 시장이 합법적인 공간으로 작동하면서 북한경제의 시장화 현상이 급격하게 확산되고 있다. 북한의 시장화 확산은 북한의 산림부문과 주민들의 산림소토지(뙈기밭) 이용에도 영향을 미치고 있다. 본 연구는 북한에서 발행하는 공식문헌과 북한의 시장화 확산에 관한 국내 관련 자료들을 검토하여 최근의 북한 경제체제 변화와 시장화 확산 현상이 산림관리에 미치는 영향을 분석하고 이에 걸맞은 대북 산림복구 지원 전략을 제시하고자 하였다. 김정은 정권은 시장경제 운영 방식을 대폭 수용한 '우리식의 새로운 경제관리 방법'을 제시하면서, 개인에게 생산물 처분권을 보장하는 포전담당제를 도입하고 외부투자를 유치하기 위한 경제개발구를 설치하는 등 시장화 확산에 따른 정책과 제도를 마련하여 추진하고 있다. 김정은 정권은 2012년 전국 황폐산림의 10년 내 산림녹화 달성을 목표로 내세우고, 경사지 경작지인 뙈기밭 회수조치를 실행하는 등 산림복구를 강력하게 추진하려는 정책의지를 제시하였다. 그러나 시장화가 확산되면서 목재수요 증가에 따른 벌채증가, 불법 땔감 채취와 판매, 생계용 임산물 채취, 식량판매를 위한 불법경작 등이 더욱 확대됨에 따라 일방적인 군중동원형 산림복구로는 한계에 봉착할 것으로 전망된다. 이에 북한당국도 경사지 산림황폐지에 나무를 심고 이에 대한 보상으로 경작권과 생산물 처분권을 허용하는 임농복합경영 방식을 도입하고, 10개년 임농복합경영전략 및 행동계획('15~'24)을 수립하는 등 시장친화적 산림정책 실행을 시도하고 있다. 따라서 앞으로 남한의 대북 산림복구 지원방식도 과거와 달리 물자나 기자재 위주의 지원방식에서 벗어나 협동농장 단위 임농복합경영의 주민 공동 사업화 방안, 개인 소토지의 산림 소득원화 지원방안, 산림사업을 활용한 산촌종합개발특구 활성화 방안 등 북한주민 공동체가 참여할 수 있는 지원모델을 마련하여 북한의 시장화 확산 및 산림정책 변화와 연계한 실효성 있는 대북 산림복구 지원전략을 구사할 필요가 있다.
