This study aimed to explore the direction of development of agricultural safety and health system in Korea based on experience on Farmers' Occupational Health Services (FOHS) of Finland. In Finland additional and specialized Occupational Health Services (OHS) for self-employed farmers were developed and have been conducted by municipal primary health care centers with cooperation of National Centre for Agricultural Health (NCAH) of Finnish Institute of Occupational Health, Social Insurance Institute (SII) and Farmers' Social Insurance Institution (FSII). Based on the study, in order to activate the FOHS in Korea, the analysis results could suggest the development of four prerequisites. Firstly, center for farmers' safety and health like NCAH, which conducts surveillance on health and safety status, standardization of intervention contents and epidemiological research is needed in national institution. Secondly, development of evaluation tools with lower cost and difficulty like walk-through survey for checking status of systems of safety in the farms is needed. Thirdly, farmers' occupational health insurance which will be initiated on near future should be connected to preventive intervention programs like FOHS. Lastly, training and qualification of more local occupational health experts and units is needed.

Jayoung was bred within the potato breeding program of Highland Agriculture Research Center (HARC), National Institute of Crop Science. It was originated from a cross made between Atlantic as a female and AG34314 as a male parent in 2003. Jayoung was evaluated as a clone number Daegwan 1-104 for the growth and tuber characteristics, yielding ability, and resistance to major potato diseases in the regional yield trials from 2006 to 2007. Finally, this clone was renamed as Jayoung and was presented to Korean Seed & Variety Service in 2007 for registration as a new potato cultivar. Jayoung has a oval shape, shallow eye depth, dark purple skinned and fleshed tuber characteristics. Its mean tuber yields from the regional yield trials was 37.3 MT/ha, and it showed the highest yield in spring cropping. Jayoung showed high resistance to both common scab (Streptomyces scabies) and potato leaf roll virus (PLRV), however it was susceptible to late blight (Phytophthora infestans). The dry matter content of Jayoung was fairy high 20.3%, therefore it is suitable for both chip processing and table usage. Its anthocyanin content was the highest in autumn cropping as 43.7 mg/100 g fresh weight and its mean anthocyanin content was 4.7 times higher than that of Jasim.

Agricultural Policy/Environmental eXtender Model(APEX)는 전 농장 또는 소규모 유역 관리에 활용하고자 개발된 모형이다. APEX는 사용자들을 고려하고 다양한 형태로 개발하였다. 사용자들이 사용하기 쉽도록 윈도우 인터페이스 형태의 WinAPEX 모듈을 개발하기도 하였으며, ArcGIS 프로그램과 연계하여 다양한 지리정보시스템을 사용할 수 있는 ArcAPEX 모듈을 개발하기도 하였다. 그러나 WinAPEX 모듈은 유역에 대한 정보를 시각적으로 확인할 수 없다는 단점을 가지고 있으며, ArcGIS 프로그램은 유료의 라이센스라는 단점을 보유하고 있다. 본 연구에서는 이러한 단점을 극복하기 위하여 APEX 모형을 GNU General Public License 기반의 Open Source Geographic Information System(GIS)인 Quantum GIS(QGIS)와 연계하여 QAPEX 모듈을 개발하고자 하였다. QAPEX 모듈은 오픈소스 기반의 QGIS 프로그램과 APEX 모형을 이용하여 무료로 사용할 수 있으며, 사용자의 편의를 위해 유역에 대한 정보를 시각적으로 확인할 수 있다. 뿐만아니라 QGIS는 사용자간의 정보 및 자료 공유에 용이한 장점을 보유하고 있어 QAPEX를 이용하는 사용자들 간의 정보 공유로 인해 원활하고 지속적인 개선이 이루어 질 것으로 기대된다.

농업 유역 내 수문 순환 및 비점오염원의 발생 및 거동에 대해서 유역단위로서의 많은 연구가 진행되어 왔다. 하지만 유역단위로서의 모의를 통해서는 필지 별 발생되는 농업 비점오염물질을 평가하고 대책을 세우기에는 한계가 있다. 따라서 농업 유역의 농경지를 대상으로 유역단위 모의가 아닌 필지단위 모의를 진행함으로써 농업 비점오염물질에 대한 관리를 해야 할 필요성이 있다. 그리하여 본 연구에서는 필지단위로 상세한 모의가 가능한 ArcAPEX 모형을 사용하였으며 모형 내 임계값 조정을 통한 유역 구분 시 우리나라 지형 및 농업특성 상 지형인자 추출의 어려움으로 Pre-defined Streams and Watersheds 기능을 활용하는 것이 농경지를 대상으로 정확한 필지 분할 및 필지 특성 반영이 될 것이라 판단하였다. 하지만 Pre-defined Streams and Watersheds 기능에 필요한 자료를 구축하는데 시간과 노력이 많이 소모되고 어려움이 있었다. 따라서 본 연구에서는 입력 자료 구축의 편의를 도모하고자 Subarea-Stream 자동 연결 모듈을 개발하여 그 활용성을 평가하고자 하였다. 이를 위해 지형적 특성으로 인해 집약적인 농업이 행해지고 있는 강원도 양구군에 위치한 해안면 유역의 농경지 경계와 하천 및 수로에 대한 자료를 Subarea-Stream 자동 연결 모듈에 입력하여 최종적으로 Pre-defined Streams and Watersheds 기능에 필요한 입력 자료를 변환시켜 모형에 적용하였다. 본 연구결과 Pre-defined Streams and Watersheds 기능에 필요한 입력 자료를 단시간에 편리하게 구축할 수 있었으며, 농경지를 대상으로 필지 단위로 분할이 된 것을 확인 할 수 있었다. 최종적으로 본 연구를 통해 지형인자 추출 오류로 인해 수계 추출 시 나타날 수 있는 문제점에 대한 해결을 할 수 있었으며 모형 내 Pre-defined Streams and Watersheds 입력 자료 구축 시 Subarea-Stream 자동 연결 모듈을 활용한다면 농업 유역 내 농경지에 대해서 편리하게 유역단위에서의 모의가 아닌 필지단위에서의 상세한 모의를 하는데 큰 기여를 할 것이라 판단된다.

This study was to explore the life history of an elderly woman who had six times of imprisonment and entered a Samchung re-education camp. This study of life history followed the analysis of Mandelbaum(1973) pointing three perspectives of life: dimensions, turnings, and adaptations. Participant's dimensions of life were exploitation of labor, hostess life for U.S. military, prison life, Samchung re-education camp, marriage with the disabled, life of a farm worker. Turnings of life were serving as a maid, confinement of prison, life of hostess for living, being remanded to Samchung re-education camp by state violence, marriage and divorce, denial of social welfare service. Adaptations of life were downright adaptation in early life, exaggerated act in juvenile reformatory, prostituted women as a simple fortune-maker, adaption as a good wife and wise mother after marriage, resistive adaption as a self-employed. and farm worker. Based upon this results outcome, discussions and implications were suggested.

Total twenty cultivars of potato (Solanum tuberosum L.) were grown at Gangneung where is located in low land of Korea. Their tubers were harvested from 100 to 120 days after planting, and over 150 g of tubers were selected for quality evaluation. Dry matter, starch, amylose in starch, ascorbic acid, protein, individual sugars and mineral were analyzed and mealiness of cooked potatoes were also evaluated by panel test. Dry mater content was the highest in 'Haryeong', 'Jayoung' and 'Shepody', and the biggest starch granules were observed in 'Jayoung' and 'Sinnamjak'. In addition, the content of amylose was highest in 'Haryeong', 'Chudong' and 'Goun'. Mineral content showed the slight difference between cultivars, but it's tendency was not clear. Vitamin C content was highest in 'Jayoung' as 62.5 $mg{\cdot}100g^{-1}$ FW, and 'Chugang' exhibited the highest content of protein. Sugar content was lower in cultivars for single one than double cropping. The lowest sugar content was observed in 'Atlantic' and 'Namseo' among cultivars for single cropping, and in 'Goun' for double cropping. As a result of analysis for quality factors, we could select nine cultivars ('Atlantic', 'Gahwang', 'Gawon', 'Goun', 'Hareong', 'Irish Cobbler', 'Jasim', 'Jayoung' and 'Shepody') with high dry matter content and low reducing sugar as a cultivar group for processing. Additionally, seven cultivars ('Chugang', 'Gawon', 'Goun', 'Hareong', 'Irish Cobbler', 'Jasim' and 'Seohong') with high mealiness and amylose content and five cultivars ('Atlantic', 'Chudong', 'Gahwang', 'Jopung' and 'Jowon') with low mealiness and amylose content were classified as groups for boiled or steam cooking and for soup or pot dishes, respectively.

The paper examines non-agricultural occupations of Korean immigrants in the Russian Far East from 1860s to 1930s. First of all, theoretical perspectives regarding immigrants\` job selection and positions in the labor market such as cultural theory, segmented labor market theory, human capital theory, and ethnic enclave theory were reviewed and then how these theories can be applied to various jobs of Korean immigrants including mining, fishing, small business, service, and miscellaneous jobs was studied. Next. this article points out that those theories cannot explain both supply and demand sides of migration simultaneously, suggesting the need to integrate two sides of migration. In order to fill out this gap in the literature, this paper suggests the integrative approach which combines supply side and demand side of migration. According to this model, several factors in the non-agricultural jabs which were affecting Korean immigration in the Russian Far East. were identified and discussed in relation with existing theoretical perspectives. Finally this paper concludes that, in order to understand Koran migration in the Russian Far East properly, we have to take into consideration simultaneously both supply-sided factors of immigration including farming-oriented characteristics of Koreans, Korean socio-economic problems preceding immigration, and self-dependent tendencies of Korean immigrants and demand-side factor like the Russian migration policy to the immigrants and various regional situations in the Russian Far East.

Due to abnormal weather conditions caused by climate change, natural disasters and damages are gradually increasing around the world. Global climate change as accompanied by warming is projected to exert adverse impact on production of potato, which is known as cool season crop. Even though, role of potato as a food security crop is expected to increase in the future, the climate change impacts on potato and adaption strategies are not sufficiently established. Therefore, this study was conducted to analyze the damage pattern of potatoes due to high temperature treatment and to evaluate the response of cultivars. T he high temperature treatment (35~38℃) induced heat stress by sealing the plastic house in midsummer (July), and the quantity and quality characteristics of potatoes were compared with the control group. T otal yield, marketable yield (>80 g) and the number of tubers per plants decreased when heat treatment was performed, and statistical significance was evident. In the heat treatment, 'Jayoung' cultivar suffered a high heat damage with an 84% reduction in yield of >80 g compared to the control group. However, in Jopung cultivar, the decrease was relatively small at 26%. Tuber physiological disturbances (Secondary growth, Tuber cracking, Malformation) tended to increase in the heat stress. Under heat conditions, the tubers were elongated overall, which means that the marketability of potatoes was lowered. T he tuber firmness and dry matter content tended to decrease significantly in the heat-treated group. T herefore, the yield and quality of tubers were damaged when growing potatoes in heat conditions. T he cultivar with high heat adaptability was 'Jopung'. T his result can be used as basic data for potato growers and breeding of heat-resistant cultivars.

토양유실은 수생태계에 악영향을 미칠 뿐만 아니라 상수원과 수계를 오염시키는 대표적인 오염원으로 간주되고 있다. 이러한 토양유실에 대한 문제를 해결하기 위해서는 무엇보다 토양유실 발생 현황을 파악하는 것이 중요하다. 토양유실 발생 현황을 파악하기 위하여 SWAT, SATEEC, APEX 등 다양한 수문모형 모델들이 개발되어 왔다. 그러나 각각의 수문모형 모델에서 어떠한 토양유실 산정 공식을 사용하였는지에 따라 모의 결과에서 다소 차이를 보이게 된다. 이에 본 연구에서는 우리나라의 필지나 유역을 대상으로 토양유실량을 산정함에 있어 어떠한 공식이 토양유실에 미치는 영향인자를 가장 잘 모의하는지 분석하여 적용하고자 하였다. 본 연구에서는 분지 특성의 유역으로, 유역 내 경작지가 집약적으로 모여 있어 토양유실 문제가 심각한 양구군 해안면 유역을 대상으로 시범 적용하였다. 토양유실량을 모의하기 위한 모델은 USLE, AOF, RUSLE, MUSLE, MUST, MUSS, MUSI의 공식 중에서 사용자가 지정한 공식에 따라 모의가 가능한 APEX 모델로 선정하였다. 본 연구에서는 양구군 해안면의 실측 유량자료를 기반으로 각 공식에 따른 토양유실량에 대하여 검정 작업을 진행하였으며, 이를 양구군 해안면의 토양유실 실측값과 비교 분석하여 해안면 유역에서 토양유실에 미치는 영향인자를 가장 잘 반영할 수 있는 공식이 무엇인지 확인하였다. 본 연구결과를 통해 양구군 해안면 유역에서 발생하는 토양유실량을 예측할 수 있는 최적의 공식을 확인함으로써 토양유실 관련 연구에 기여할 수 있을 것으로 기대된다. 그러나 본 연구에서는 양구군 해안면 유역을 대상으로 최적의 토양유실 산정공식을 찾았지만, 타 유역의 토양유실량을 평가하기에는 한계가 있다. 따라서 APEX를 이용한 전국단위 토양유실량 평가를 통해 범용화 할 수 있는 공식을 찾는 추가적인 연구를 진행한다면 보다 정밀한 토양유실량 산정이 가능하게 되어 향후 우리나라 토양유실 관련 연구에 큰 기여를 할 것으로 기대된다.
