  • Extreme rainfall will become intense due to climate change, increasing inundation risk to agricultural land. Hydrological and hydraulic simulations for the entire watershed were conducted to analyze the impact of climate change. Rainfall data was collected based on past weather observation and SSP (Shared Socio-economic Pathway)5-8.5 climate change scenarios. Simulation for flood volume, reservoir operation, river level, and inundation of agricultural land was conducted through K-HAS (KRC Hydraulics & Hydrology Analysis System) and HEC-RAS (Hydrologic Engineering Center - River Analysis System). Various scenarios were selected, encompassing different periods of rainfall data, including the observed period (1973-2022), near-term future (2021-2050), mid-term future (2051-2080), and long-term future (2081-2100), in addition to probabilistic precipitation events with return periods of 20 years and 100 years. The inundation area of the Aho-Buin district was visualized through GIS (Geographic Information System) based on the results of the flooding analysis. The probabilistic precipitation of climate change scenarios was calculated higher than that of past observations, which affected the increase in reservoir inflow, river level, inundation time, and inundation area. The inundation area and inundation time were higher in the 100-year frequency. Inundation risk was high in the order of long-term future, near-term future, mid-term future, and observed period. It was also shown that the Aho and Buin districts were vulnerable to inundation. These results are expected to be used as fundamental data for assessing the risk of flooding for agricultural land and downstream watersheds under climate change, guiding drainage improvement projects, and making flood risk maps.

  • 본 연구는 경남농산물 소득자료를 이용하여 시설 파프리카와 시설 딸기, 그리고 노지 마늘과 노지 시금치를 대상으로 경남지역 채소류 재배면적 반응함수를 추정하였다. 작물별 재배면적 반응함수 추정결과에 따르면 시설 파프리카의 경우 농업조수입이 증가한 영향보다는 농업경영비 감소와 가격변동 위험의 감소에 따라 재배면적이 증가한 것으로 나타났다. 시설 딸기의 경우 농업조수입이 증가했음에도 불구하고 농업경영비가 증가 하였고, 가격변동 위험이 상대적으로 더 컸기 때문에 재배면적이 감소하였다. 노지 마늘과 시금치의 경우 농업조수입이 증가하였음에도 불구하고 가격변동위험이 크기 때문에 농가는 재배면적을 늘리지 않은 것으로 밝혀졌다. 추정결과의 정책적 함의는 다음과 같다. 농산물 가격변동 위험은 시설 작물보다 노지에서 재배되는 작물의 경우 상대적으로 더 크다. 따라서 경상남도에서는 노지 작물에 우선하여 농업수입보장보험을 도입해야 할 것이다. 반면에 시설 작물의 경우 농업경영비 부담이 매우 크다. 따라서 지방정부는 난방비를 포함한 농업경영비를 줄이기 위하여 노후 시설을 교체하고 스마트팜 시설 확충 등에 주력해야 할 것이다.

  • This paper describes the current status of musculoskeletal disorders(MSDs) and its ergonomic risk factors, including the preventive intervention in terms of the working conditions and health promotion among agricultural workers. Korean agricultural workers have been exposed to the poor working condition. They have suffered from a variety of work-related injury and diseases more than the general population or the other occupational group. MSDs are one of the most prevalent problems threatening the agricultural worker's health and quality of life. Low back pain, osteoarthritis of hip and knee joint and carpal tunnel syndrome are well known MSDs that was found easily and frequently among agricultural workers. MSDs are worsened by poor ergonomic working conditions such as heavy weight lifting, repetitive movement and awkward posture which involves squatting with long sitting work on the ground, long working hours and heavy workload which are inherent in the greater part of agricultural works. Even though Korean agricultural workers are very weak population in terms of occupational safety and health, no many studies were conducted in the past and no many social and institutional supports were provided sufficiently. We need more interests and efforts in agricultural fields to improve its working condition and to promote health status of agricultural workers.

  • A high prevalence of farmer's work-related musculo-skeletal disorders (MSDs) have been reported in precedent studies. Risk factors - physical, chemical, biological, ergonomic risk factor etc. - in farm-work were identified by previous studies. To prevent farmers from exposing to them and reduce, Agricultural Safety Technology were introduced and used on farm. The purpose of this study is to review and summarize the agricultural safety technology on farm in Korea. According to strategy principles, this technology is classified as four criteria - workload reduction by reducing awkward posture, workload reduction by using manual material handling aids, Comfort improvement by protecting worker from hot, cold environment and work efficiency improvement by workplace redesign and cultivation modification. This technology includes transporting tools, working cloth, personal protective equipment, and pesticide-proof Clothing. Anthropometric study of Korean farmers was also carried out to support the development of equipment and clothes. In long terms, it needs to precaution activity from risk factors by using cultivation modification and working improvement. Although working condition gets better and workload reduce by this technology, it required customized safety technology in each crops - rice cultivation, horticulture and livestock farming. And farmers should use the assistive technology and participate voluntarily in ergonomic intervention program.

  • 과수의 개화기 꽃감염 위험기간 중의 강우가 화상병의 발병에 어느 정도 영향을 주었는지 조사하였다. 2015년부터 시작된 충남지역의 과수 화상병 발병 기간 중에서 2020년부터 2022년의 발병 규모가 가장 크게 변화하였는데, 2020년에는 63개 과원에서 발병하였고, 2021년에는 170 과원으로 크게 증가하였으나, 2022년에 46개 과원으로 감소하였다. 2022년에는 발병과원의 발병 나무 가지에 형성된 궤양증상이 감소하였고, 이것은 개화기 건조한 날씨에 의한 것으로 평가 되었다. 즉, 꽃감염 위험기간 중의 강우 여부 및 누적 강수량에 따라 그 해의 화상병 발병은 증가하거나 감소하였다. 이러한 경향은 사과와 배가 재배되는 조사지역 모두에서 유사한 경향이었고, 꽃감염 위험시기의 기상환경 중 강우는 월동 궤양으로부터 활성화된 병원균의 전반과 꽃 감염에 큰 영향을 주었으며, 특히 꽃감염 위험경보가 시작되는 초기 3일간의 강수량은 발병 규모를 결정하는 요인으로 확인되었다.

  • Wastewater reuse are exposed public health risk by pathogens. Therefore, this study was examined for microbial risk assessment after irrigation as treated wastewater in paddy rice plots. Five treatments were used: biofilter effluent, UV disinfected water, pond treatment, wetland treatment and conventional irrigation water. Risk assessment was calculated based on the beta-Poisson model by concentration of E. coli from 2003 to 2005. Monte-Carlo simulation (n=10,000) was used to estimate the risk characterization of uncertainty. The risk range was from $10^{-5}$ to $10^{-8}$ except biofilter effluent was $10^{-4}$ in June. The USEPA(1992) has recommended that risk of < $10^{-4}$ is acceptable level of safety for potable waters. In 2005, risk value was lower than 2003, 2004 because of the first irrigation for plowing water is lower E. coli concentration used tap water. It is shown that the first irrigation water quality was important for wastewater irrigation in paddy. UV disinfection and natural treatment used pond and wetland were thought to be an effective for wastewater reuse.

  • Korea's self-sufficient food ratio on a quantity basis remained a low 27.6 per cent for cereals in year 2004. Even the public auction of imported rice from the United States kicked off a couple of days ago to allow foreign rice to be sold directly to consumers on the Korea market for the first time. Therefore the safety of imported food must be a great concern of Korean consumers. All imported agricultural products are supposed to be quarantined for controlling the insect and inspected for the potent risk like residual pesticides, aflatoxin, sulfur dioxide and genetically modified. agricultural products. The 12 percent of agricultural products contained the insects detected by National Plant Quarantine was fumigated with methyl bromide or aluminum phosphide and entered the custom. The most large portion of violated agricultural products (24 cases in 2004) inspected by Korea Food and Drug Administration was dried herbal medicinal foods contaminated by sulfur dioxide which must be treated when they were dried in China. The second factor made the imported agricultural products to be criminals (19 cases in 2004) was residual pesticides. Genetically modified agricultural products like soybean and corn are under control by labelling in Korea. Genetically modified soybean and corn have been used for oil expression mostly. It is the time to set up realistic risk assessment system for our consumer with the pouring imported agricultural products.
