Objective:This study introduced the status of studies and the projects related with agricultural accident prevention carried out by the Rural Development Administration. This study was conducted to promote Korean farmers' agricultural safety activation by analyzing study trends on farmers' agricultural work safety. Background: Agriculture is one of the dangerous industries, and the agricultural accident rate is on the rise, due to recent serious aging and increased female work force. Such a phenomenon emerges as a serious problem from the social perspective, and therefore measures for farmers' healthy and safe agricultural activities and accident prevention are required. Method: This study conducted literature review related with domestic and international agricultural safety and health. This study also examined the hazard factors of agricultural labor and injuries, agricultural safety and health system and policy, support and education for farmers' safety practice, and the status of convenience tools and protection equipment, based on major study activities performed by the Rural Development Administration for recent four to five years. Results: Through the study results, the status of Korea's agricultural safety system, compensation support policy, safety education of farmers for actual practice, and diverse channels including media were confirmed. This study also presented the R&D implementation status on convenience equipment and protective gear to prevent agricultural diseases and safety accidents. Conclusion: This study found out that continuous monitoring and efforts are required to prevent accidents for the Korea's agricultural labor environment and agricultural safety, and that social bond of sympathy formation is demanded through effect analysis on the implemented projects including education and support projects. Furthermore, it can be understood that agricultural accident prevention should be carried out through shift from current government-led top down approach to bottom-up approach from itself. Application: The results of this study can be utilized as useful data for farmers' safety and health.

본 연구는 2009 개정 교육과정 중심의 정규교과에 활용 가능한 수학 과학 스마트 교육용 콘텐츠 410개와 콘텐츠 활용가이드북 및 이를 서비스할 수 있는 플랫폼을 개발하였다. 이를 위해 수학 과학 관련 콘텐츠 분석 및 농산어촌 수학 과학교사 사전 설문조사 분석, 2009 개정 교육과정 분석을 기반으로 학년별/과목별 20개 주제를 선정하여 수학 210개, 과학 200개 총 410개 개발주제 및 내용 등을 선정하였다. 선정된 주제목록 및 구현방안은 교과별 관련 전문가 검토를 통해 타당도 검증을 실시하였으며, 검토의견을 반영하여 최종 수정 후 스토리보드 및 콘텐츠를 설계 및 개발하였다. 이를 창의과학교실 및 농산어촌 학교를 선정하여 시범 적용한 후 적용 결과를 분석하여 콘텐츠 개발 방향을 정립하였으며, 전문가 검토를 실시하여 수정 보완 후 최종 플랫폼에 탑재하여 오픈하였다. 도 농간 학력격차가 큰 수학 과학 학습에 ICT를 활용할 수 있도록 스마트 교육용 콘텐츠를 개발, 보급함으로써 농산어촌 학습 환경개선 및 농산어촌 학생들의 자기주도적 학습력 신장에 도움이 될 것으로 기대한다.

Due to the recent integrated water management policy, it is important to identify a reliable supply amount for establishing an agricultural water supply plan. In order to identify the amount of agricultural water supply, it is essential to calculate the discharge by measuring the water level and flow velocity of reservoirs and canal agricultural water, and quality control to ensure reliability must be preceded. Unlike agricultural reservoirs, canal agricultural water are more sensitive to the surrounding environment and reservoir irrigation methods (continuous, intermittent irrigation, etc.), making it difficult to estimate general water level patterns and at the same time a lot of erroneous data. The Korea Rural Community Corporation is applying a filter technique as a quality control method capable of processing large quantities and real-time processing of canal agricultural water level data, and applicability evaluation is needed. In this study, the types of errors generated by the automatic water level measurement system were first determined. In addition, by using the manual quality control data, a technique with high applicability is derived by comparing and analyzing data calibrated with Gaussian, Savitzky-Golay, Hampel, and Median filter techniques, RMSE, and NSE, and the optimal parameters of the technique range was derived. As a result, the applicability of the Median filter was evaluated the highest, and the optimal parameters were derived in the range of 120min to 240min. Through the results of this study, it is judged that it can be used for quantitative evaluation to establish an agricultural water supply plan.

The purpose of this study was to develop an in-service education program on multifunctionality of agriculture and rural areas. The in-service education program for general agricultural education was developed by reviewing literature, analyzing domestic in-service education programs. The program consisted of 3 fields - understanding, experiencing multifunctionality, and applying it to classroom, and contents validity was evaluated by 3 experts. And the program was applied to 268 elementary and secondary school teachers. Before and after the in-service education program, the survey was conducted. The survey questions were about motivation of participation, satisfaction level of program, and so on. Based on the analysis of survey data, some recommendations were suggested.

Soybean agglutinin (SBA) is an anti-nutritional factor of soybean, affecting cell proliferation and inducing cytotoxicity. Integrins are transmembrane receptors, mediating a variety of cell biological processes. This research aims to study the effects of SBA on cell proliferation and cell cycle progression of the intestinal epithelial cell line from piglets (IPEC-J2), to identify the integrin subunits especially expressed in IPEC-J2s, and to analyze the functions of these integrins on IPEC-J2 cell cycle progression and SBA-induced IPEC-J2 cell cycle alteration. The results showed that SBA lowered cell proliferation rate as the cell cycle progression from G0/G1 to S phase (P < 0.05) was inhibited. Moreover, SBA lowered mRNA expression of cell cycle-related gene CDK4, Cyclin E and Cyclin D1 (P < 0.05). We successfully identified integrins ${\alpha}2$, ${\alpha}3$, ${\alpha}6$, ${\beta}1$, and ${\beta}4$ in IPEC-J2s. These five subunits were crucial to maintain normal cell proliferation and cell cycle progression in IPEC-J2s. Restrain of either these five subunits by their inhibitors, lowered cell proliferation rate, and arrested the cells at G0/G1 phase of cell cycle (P < 0.05). Further analysis indicated that integrin ${\alpha}2$, ${\alpha}6$, and ${\beta}1$ were involved in the blocking of G0/G1 phase induced by SBA. In conclusion, these results suggested that SBA lowered the IPEC-J2 cell proliferation rate through the perturbation of cell cycle progression. Furthermore, integrins were important for IPEC-J2 cell cycle progression, and they were involved in the process of SBA-induced cell cycle progression alteration, which provide a basis for further revealing SBA anti-proliferation and anti-nutritional mechanism.
