Various infectious diseases have threatened swine industries in Korea. One of the major risk factors of disease spread is livestock transport vehicle. For this reason, all abattoirs are required by law to have vehicle washing and disinfection facilities. However, detailed guidelines for cleaning and disinfection procedures were not provided. So in this study, assessment by visual observation was conducted to evaluate how well the cleaning and disinfection procedures of livestock transport vehicles have been performed in four different abattoirs in Jeonbuk, Korea. The observation included length of car washing time, the number of washing bay, type of washperson, type of disinfectant application, length of disinfection time, and compliance of driver's hygienic procedure. Every vehicle in all abattoirs conducted washing and disinfection procedure. However, there were procedural differences for each abattoirs and defects in the washing and disinfection procedures. In addition to that, the compliance of driver's hygienic procedure was not sufficient. Hence, detailed manuals on washing and disinfection procedures for involved people are required and it is necessary to establish an inspection and evaluation system.

Pre-drainage of groundwater in the roof aquifer by boreholes is the main method for prevention of roof water disaster, and the drop in the water level during the drainage leads to the variation of the local stress in the overlying strata. Based on a multitude of boreholes for groundwater drainage from aquifer above the 1303 mining face of Longyun Coal Mine, theoretical analysis and numerical simulation are used to investigate the local stress variation in the process of borehole drainage. The results show that due to the drop in the water level of the roof aquifer during the drainage, the stress around the borehole gradually evolved. From the center of the borehole to the outside, a stress-relaxed zone, a stress-elevated zone, and a stress-recovered zone are sequentially formed. Along with the expansion of drainage influence, the stress peak in the stress-elevated zone also moves to the outside. When the radius of influence develops to the maximum, the stress peak position no longer moves outward. When the coal mining face advances to the drainage influence range, the abutment pressure in front of the mining face is superimposed with the high local stress around the borehole, which increases the risk of stress concentration. The present study provides a reference for the stress concentration caused by borehole drainage, which can be potentially utilized in the optimal arrangement of drainage boreholes in underground mining.

복합 소재는 금속보다 가벼운 특성을 가져 경량화가 필수인 항공 산업에 널리 사용되고 있다. 하지만 복합소재는 생산 공정 중 내부 보이드 형성, 접착제 혼합 불량, 미접착 부분 발생 등 결함 요소가 발생할 수 있고, 저 에너지 충격에 의한 미세균열 및 층간분리가 발생할 위험이 있다. 그러므로 구조물 손상검사가 필수적으로 요구된다. 이에 FBG를 이용한 구조 건전성 모니터링이 주목받고 있다. FBG는 기존의 전기적 센서에 비해 전기적 노이즈 영향을 받지 않고 부식에 강하며 멀티플렉싱이 가능하다는 장점이 있다. 하지만 FBG를 계측하는 인터로게이터는 대형 구조물 계측을 전제로 만들었기 때문에 가격이 고가이며, 크기가 큰 단점이 있다. 이에 본 논문에서는 광 스위치와 WDM필터, LTF를 이용해 무인항공기나 소형항공기에 사용할 수 있도록 저가형 인터로게이터를 설계하여, 기존의 고가 인터로게이터와 비교를 진행하였다.

Background: The Environmental Health Action Program was a national project carried out from 2012~2021. It was aimed at developing public technologies to protect people's health from various environmental hazards. Objectives: One of the final goals of the project was "creating health benefits worth more than 179.2 billion won by reducing the environmental burden of disease." This study aims to evaluate whether the program sufficiently achieved the planned benefits. Methods: In order to secure consistency in evaluation, we applied the same equation used in the goal-setting process. It is comprised of six parameters to estimate the benefit: 1. The amount of medical expenses for environmental diseases; 2. The attributable proportion of environmental risk factors' 3. The rate of reduction in medical expenses for environmental diseases; 4. R&D project contribution; 5. The proportion of successful policy reflection; and 6. The contributions of the project. The corresponding variables were estimated at the end of the project, and the health benefits of the project were recalculated using the newly estimated variables. Results: It was estimated that a total of 195 billion won in health benefits occurred or will occur from 2015 to 2026. The main contributors for achieving the target were an increase in medical expenses for environmental diseases, a high score in the R&D project contribution, and the proportion of successful policy reflection. Conclusions: Technically, the equation used in the project is about medical expenses for environmental diseases rather than about the environmental burden of disease. There are several benefits of using the environmental burden of disease in the evaluation of public health policies. In further studies, developing a policy evaluation framework using indicators such as population attributable fraction would be needed.

Recently, interest in smart factories is increasing. Investments to improve intelligence/automation are also being made continuously in manufacturing plants. Facility automation based on sensor data collection is now essential. In addition, we are operating our factories based on data generated in all areas of production, including production management, facility operation, and quality management, and an integrated standard information system. When producing LCD polarizer products, it is most important to link trace information between data generated by individual production processes. All systems involved in production must ensure that there is no data loss and data integrity is ensured. The large-capacity data collected from individual systems is composed of key values linked to each other. A real-time quality analysis processing system based on connected integrated system data is required. In this study, large-capacity data collection, storage, integration and loss prevention methods were presented for optimization of LCD polarizer production. The identification Risk model of inspection products can be added, and the applicable product model is designed to be continuously expanded. A quality inspection and analysis system that maximizes the yield rate was designed by using the final inspection image of the product using big data technology. In the case of products that are predefined as analysable products, it is designed to be verified with the big data knn analysis model, and individual analysis results are continuously applied to the actual production site to operate in a virtuous cycle structure. Production Optimization was performed by applying it to the currently produced LCD polarizer production line.
