Purpose: As part of the government's national policy agenda, one of the key initiatives in the Rural Convergence Industry is the selection and cultivation of certified operators. This study aims to specifically analyze the business performance of certified operators, first selected in 2015, based on their characteristics, and to propose improvement measures for the Rural Convergence Industry based on the analysis results. Methods: Data were collected from the certification (renewal) records of the Gyeongnam Sixth Industry Support Center from 2015 to 2023. The R program (R Core Team 2023) was used for data analysis. Results: The performance and role of certified operators are receiving attention to spread and increase awareness of the Rural Convergence Industry. While the location, gender of the representative, type of certified operator, type of convergence industry (6th industry), and main product did not have statistically significant effects on the sales and job changes of certified operators, the sales growth rate according to the management period of certified operators was found to have a statistically significant effect. Conclusion: It was observed that the longer the management period of the certified operator, the more sales increased, with a significant rise in sales growth rate at the early stage of the certified operator. This suggests that to revitalize and successfully promote the Rural Convergence Industry, it is necessary to strengthen the operator certification system and continuously implement various projects to enhance the capabilities of certified operators.

A survey on the understanding of environment-friendly certification system was conducted for certified operators. The survey included the necessity of certification system, difficulties in producing certified products, and general evaluation of the current certification system. Certified operators were generally satisfied with the certification system in terms of the certification standards, the public subsidy programs, and the farm management costs. Individuals with parallel production farms were relatively less satisfied than the group with full-time organic farmers. Analysis using the ranking probit model indicated that the longer the certification experience, the more highly aware the need for the certification system was. Our results indicated that policy strategies are needed to enlarge the marketability of environment-friendly agricultural products since economic factors of organic products were the most important factor for maintaining and expanding certification in overseas as well as in Korea. It seems to be necessary to implement economic triggers for certified operators to continue their certification programs by promoting the transition period certification for individual farms in parallel with conventional agriculture. Analysis of the variables correlated with the expansion of environment-friendly agriculture by the logit model implied that certified operators with the younger age and higher annual incomes were more likely to expand environment-friendly agriculture. Therefore, it might also be important to provide financial support and incentives for new entry farmers to participate in environment-friendly agriculture and establish a system to share the know-how of successful certified organic farmers.

두경부 질환의 인터벤션 시술 시 시술자가 받는 피폭선량의 평가 및 감소연구를 위한 선행 연구로써, 이온 전리함을 이용하여 인터벤션 시술 시 시술자의 위치하는 공간선량 분포를 측정하였다. Bi-plane 인터벤션 시술 장비를 대상으로 4개 구역(45, 135, 225 그리고 315도)으로 나누어 가상의 시술자가 있다는 가정아래에 시술자의 결정장기위치에서 거리(80, 100, 120, 그리고 140 cm)에 따라 조사선량을 측정하였으며, 방사선발생장치의 위치를 변화시켜 선량변화를 분석하였다. 시술자의 대부분이 위치하는 225도의 구역의 조사선량은 가장 가까운 거리인 80 cm에서 시술자 눈의 높이에서 114.5 mR/h, 가슴의 높이는 143.1 mR/h, 그리고 생식기위치는 147 mR/h이었다. 그리고 방사선 발생장치의 위치를 시술자 가까이로 변화시켰을 경우, 평균적으로 $18.1{\pm}10.5%$의 선량이 증가하였다. 본 연구에서 인터벤션 시술 동안 시술자가 위치할 수 있는 곳의 공간선량분포를 확인하였으며, 본 연구 결과를 통하여 시술자의 방사선 방어에 대하여 구체적인 계획을 수립할 수 있을 것이라 사료된다.
