본 연구는 경상남도 내 유통되는 양식 어류 116건을 대 상으로 PLS 도입 이후 동물용의약품 128종 142항목의 잔 류 실태를 분석하고, PLS 도입 전후의 변화를 평가하였다. 경상남도 양식 어류 116건 중 54건(46.6%)에서 잔류동물용 의약품이 검출되었으며, 이 중 넙치 1건에서 옥시테트라사 이클린이 기준치를 초과하였다. PLS 도입 전인 2023년의 검출률(49.6%)과 2024년의 검출률(46.6%)은 유의미한 차이 가 없었으나, 부적합률은 2023년 2.4%에서 2024년 0.9%로 감소했다. 어종별 잔류동물용의약품 검출 빈도는 미꾸라지 (81.8%), 조피볼락(78.6%), 넙치(68.4%) 순으로 높았다. PLS 도입 전후 모두 조피볼락이 해수어 중 검출률이 가장 높았 으며, PLS 도입 이후 넙치와 강도다리의 검출률이 증가한 반면, 농어와 숭어의 검출률은 감소했다. 물질별 검출 빈도 는 옥시테트라사이클린(22.4%), 엔로플록사신(19.8%), 트리 메토프림(8.6%) 순으로 높았으며, 2023년 연구에서도 유사 한 경향을 보였다. 2024년에는 미꾸라지에서 엔로플록사신 이 81.8%의 높은 검출률을 보였다. 넙치에서 옥시테트라사 이클린의 검출률은 2023년 45.5%에서 2024년 6 3 .2%로 증 가했으며, 조피볼락에서 트리메토프림의 검출률은 40.7%에 서 57.1%로 증가하였다. MRL 대비 검출 농도의 평균은 2023년 14.1%에서 2024년 14.2%로 유사한 수준이었고, 트 리메토프림, 플루메퀸, 아목시실린을 제외한 대부분의 항목 에서 MRL 대비 평균 검출농도가 증가했다. 위해성 평가 결과, 검출된 9항목에 대한 위해도는 0.0335% 이내로 매우 안전한 수준으로 평가되었다. 그러나 일부 어종에서 특정 한 약물의 잔류성이 강하다고 추정되므로, 각 어종의 특성 에 맞는 휴약기간 등의 명확한 관리 지침이 마련되어야 할 것이다. 또한 PLS 도입의 효과를 정확하게 평가하기 위해 서는 지속적인 모니터링이 필요할 것으로 보인다.
Today, as the social demand for tap water safety and the need for an ICT-based intelligent integrated control system increase, K-water (Korea Water Resources Corporation) is building and operating a ‘Water pipe monitoring CCTV system’ to quickly respond to crises in the event of a water leak. However, in the case of the existing system, when the CCTV rotates, the image information and the mapped water pipe image do net match, so the operator has the limitation that the water pipe image must be mapped anew every time. In this paper, in odert to solve the above problems, we propose an improved system that can extract feature points from CCTV images, detect changes in the coordinate values of the feature points, and automatically transform the location of the water pipe image by utilizing LoFTR (Detector-Free Local Feature Matching with Transformer), a type of deep learning image matching algorithm that is actively being studied in th field of the latest computer vision, and examine its effectiveness.

Recently, SDAS(Advanced driver-assistance system) are being installed to assist driving of vehicles and improve driver convenience. LDWS(Lane departure warning system) and FCWS(Forward collision warning system) are the core of the technology. Among these, FCWS is evaluated as a key assistive technology to prevent vehicle crashes. Accordingly, many algorithms are being developed and tested to improve detection speed and actual detection algorithms are being commercialized. In this paper, We propose the design of a system that optimizes FCWS speed by considering the AI performance of the terminal device when implemented as an embedded system.
As discarded fishing gear settles or floats on the seabed, it destroys the spawning and habitat of fisheries resources that causes various safety accidents and adverse effects on the environment, such as generating microplastics and causing ship accidents. In order to solve this problem, this study is intended to present an implementation plan for establishing a fishing gear deposit system in order to use it as basic data for establishing policies for fishing gear management in Korea. In order to successfully implement the fishing gear deposit system, the deposit system must be established in the form of fishing gear completed at the production stage. It was found that the marking of the object should be easy, and that determining an appropriate deposit amount to motivate the return of waste fishing gear and establishing a convenient return procedure for returned waste fishing gear were important factors. In addition, transparent management of unreturned deposits and mandatory use of fishing gear subject to the deposit system for fishermen will be necessary. The role of a specialized organization to manage and operate all of these procedures is also very important. It is necessary to establish a new mandatory provision in the Fisheries Act to require fishermen who directly use fishing gear to use fishing gear with a deposit refund mark, and to ensure the implementation of the deposit system by linking it with the evaluation items of government policy projects. Since the main purpose of the deposit system is to collect discarded fishing gear, a support plan will be necessary in accordance with the purchase project for fishing waste salvaged by local governments in 2020.
2021년 7월 자치경찰제가 실시되면서, 지역 안전에 대한 관심이 고조 되었다. 지금까지 지역 안전은 전통적 의미의 치안 관점에서 접근하였으 나, 안전에 대한 여성의 두려움이 증가하면서, 지역에서의 안전이 더이상 치안의 차원에 머무를 수 없게 되었다. 그러나, 지역 안전을 확인할 수 있는 안전지표는 안전에 대한 취약성을 주로 측정하고 있어, 여성의 범 죄에 대한 두려움이나 예방적 차원의 지표는 포함되어 있지 않았다. 따 라서, 본 연구는 지역의 안전을 측정할 수 있는 새로운 안전지표의 구성 이 필요하며, 새로운 안전지표는 성인지적 관점의 적용으로부터 출발하 였다. 새로운 안전지표는 기존 안전이론과 함께 성인지 감수성 이론에 기반하여, 4개 영역 22개 지표를 구성하였다. 이 연구는 새로운 안전지 표를 개발하기 위한 것으로 지표가 적합한지를 탐색적으로 조사하였다. 이를 위해 성인지 전문가와 자치경찰 전문가를 대상으로 델파이 조사를 실시한 후 적합한 지표를 제시하였다. 조사 결과, 영역별 적합도는 높은 편이었고, 22개 세부 지표 가운데 14개 지표는 적합, 1개 지표는 부적 합, 7개 지표는 고려할 필요가 있는 것으로 나타났다. 이러한 결과는 향 후 자치경찰제 실시에 따른 지역 안전 지표를 구성하는 데 기여할 것으 로 기대할 수 있다.
Production management in the automobile parts industry is carried out according to the production plan of the customer, so it is important to prevent shortages in product supply. As the product composition became increasingly complex, the MES System was built for the purpose of efficient production plan management and inventory management, but its utilization is low. This study analyzed the problems of the MES system and sought to improve it. Through previous studies, it was confirmed that the inventory management of the pull approach that actually occurred in the warehouse is more suitable than the push approach based on the forecast of the warehouse for the volatility, complexity, and uncertainty of orders in the auto parts industry. To realize this, we tried distributed MRP by using the ADO function of VBA to link the standard information of the MES system with Excel and change the structure of the BOM table. Through this, it can help increase the accuracy of production planning and realize efficient inventory management, thereby increasing the utilization of the MES system in the auto parts industry and enhancing the competitiveness of the company.
This was written to introduce the case of establishment and implementation of the Disclosure procedure related to patient safety accidents at Hospital A. The process of establishing the Disclosure procedure of Hospital A consisted of a survey of professors in charge of Clinical Performance Improvement, the formation of consensus within the management, the establishment of procedures through discussion in the relevant departments and committees, and the enactment and implementation of regulations. In addition, in order to apply the regulations to the field, various education and public relations strategies for employees, as well as management procedures for cases of violation of the patient safety culture. And now, psychological support programs are being explored to protect the employees who are the second victims. Continuous efforts to improve “communication know-how” should be made by collecting data and analyzing cost effects. Therefore, legal support such as the Apology Act is also needed to activate and protect patient safety communication.
Through the process of chemical vapor deposition, Tungsten Hexafluoride (WF6) is widely used by the semiconductor industry to form tungsten films. Tungsten Hexafluoride (WF6) is produced through manufacturing processes such as pulverization, wet smelting, calcination and reduction of tungsten ores. The manufacturing process of Tungsten Hexafluoride (WF6) is required thorough quality control to improve productivity. In this paper, a real-time detection system for oxidation defects that occur in the manufacturing process of Tungsten Hexafluoride (WF6) is proposed. The proposed system is implemented by applying YOLOv5 based on Convolutional Neural Network (CNN); it is expected to enable more stable management than existing management, which relies on skilled workers. The implementation method of the proposed system and the results of performance comparison are presented to prove the feasibility of the method for improving the efficiency of the WF6 manufacturing process in this paper. The proposed system applying YOLOv5s, which is the most suitable material in the actual production environment, demonstrates high accuracy (mAP@0.5 99.4 %) and real-time detection speed (FPS 46).
In the era of the 4th industrial revolution driven by the convergence of ICT(information and communication technology) and manufacturing, research on smart factories is being actively conducted. In particular, the manufacturing industry prefers smart factories that autonomously connect and analyze data. For the efficient implementation of smart factories, it is essential to have an integrated production system that vertically integrates separately operated production equipment and heterogeneous S/W systems such as ERP, MES. In addition, it is necessary to double-verify production data by using automatic data collection technology so that the production process can be traced transparently. In this study, we want to show a case of data-centered integration of a large aircraft parts processing factory that requires high precision, takes a long time, and has the characteristics of processing large raw materials. For this, the components of the data-oriented integrated production system were identified and the connection structure between them was explained. And we would like to share the experience gained through the design and implementation case. The integrated production system proposed in this study integrates internal components based on data, which is expected to serve as a basis for SMEs to develop into an advanced stage, and traces materials with RFID technology.
Today, the question on the legal instruments of international organisations that impose direct sanctions on individuals and legal entities have surfaced, such as the United Nations Security Council (UNSC) Resolutions. States are obliged to implement the UNSC Resolutions but would face difficulties in this course. The UNSC’s coercive approach rubs international security against democratic legitimacy, especially when the Resolutions violate due process of law, principle of legality and human rights. To date, Indonesia’s stance on international law (including UNSC Resolutions) under its legal system remains unclear. This study analyses the implementation of the UNSC Resolutions in Indonesia, which has no uniformity without a UN Act. The case of North Korean vessel, MV Wise Honest, highlights the growing confusion in Indonesia because violation of the UNSC Resolutions has not been governed. Conclusively, Indonesia needs to enact a UN Act to provide legal certainty in the implementation of the UNSC Resolutions.
