Biomedical laboratory is full of risks. Risk could be biological, chemical, radioactive, mechanical, physical, fire and electrical. All possible risks need to be identified, evaluated and controlled. A risk management system must be in place to prevent accident or loss of lives and to improve overall workplace safety and productivity. Safety in laboratory is a combination of appropriate risk management system, engineering controls and technical facilities, administrative controls and safety procedures and practices. Laboratory safety culture must be developed so that exposure to hazards for laboratory personnel, community and environment will be minimized or eliminated. In this review, importance of safety in a biomedical laboratory and risk management will be discussed.

Recently, utilization of PMIS(Project Management Information System) is in high demand as it is desired to advance the construction market through cost reduction and quality improvement within the given schedule. However, PMIS developed by individual projects are mostly evolving around construction progress status due to the temporary nature of development period and use of the system by project executers is no more than perfunctory that results in limiting the effective communication between the project owner, project manager and constructor. Therefore, the purpose of this paper is to review the PMIS developed so far, and present the direction for an effective PMIS.

Since 1995, the facility of class 1 and 2, classified by law had been subject to system of post maintenance management where periodic safety inspection and diagnosis to identify any problems and to take appropriate measures as a matter of urgency. Although the standards and systems had been revised many times for continuous improvement due to surrounding environmental factors, the technical factors and other factors for improvements, continuous researches and efforts are needed to ensure even higher effectiveness. Furthermore, the consciousness of the management body that executes and implements such improvements for facility management is most important. Therefore in this study, through such analysis, more realistic management consciousness review was performed. Also the direction for improvements is proposed, to carry out more effective facility safety management systems implementation.

Plant expression systems have been developed to produce anti-cancer vaccines. Plants have several advantages as bioreactors for the production of subunit vaccines: they are considered safe, and may be used to produce recombinant proteins at low production cost. However, several technical issues hinder large-scale production of anti-cancer vaccines in plants. The present review covers design strategies to enhance the immunogenicity and therapeutic potency of anti-cancer vaccines, methods to increase vaccine-expressing plant biomass, and challenges facing the production of anti-cancer vaccines in plants. Specifically, the issues such as low expression levels and plant-specific glycosylation are described, along with their potential solutions.

Elimination of squeal noise generated during brake application is an important task for the improvement of comforts in vehicles. In this paper, the structure of the wet brake and its operation are described first, and the cause of the noise is analyzed by identifying how the factors such as torque, speed, oil pressure, lubricant, and friction material affect the noise. To verify the mechanism of generation of the noise, several experiments of brake applications are executed, Based upon the review on the technical papers and the results from the experiments, several solutions to reduce the noise, available in real applications, are suggested, and the feasibilities of them are confirmed through the applications to the current system.

Cyber-physical systems (CPSs) are an emerging discipline that involves engineered computing and communicating systems interfacing the physical world. The widespread applications of CPSs still face enormous challenges because of the lack of theoretical foundations. In this technical survey, we review state-of-the-art design techniques from various angles. The aim of this work is to provide a better understanding of this emerging multidisciplinary methodology. The features of CPSs are described, and the research progress is analyzed using the following aspects: energy management, network security, data transmission and management, model-based design, control technique, and system resource allocation. We focus on CPS resource optimization, and propose a system performance optimization model with resource constraints. In addition, some classic applications (e.g., integrating intelligent road with unmanned vehicle) are provided to show that the prospects of CPSs are promising. Furthermore, research challenges and suggestions for future work are outlined in brief.

The introduction, construction, and operation of the safety and health management system of specialized construction companies have a problem incurred in the cost of introducing and operating the safety system. In addition, it is difficult to establish a virtuous cycle system to build a safety system, obtain a certification, and settle in a harsh environment that does not have technical personnel in construction safety. The purpose of this paper is to investigate and review the literature related to the safety and health management system of the construction industry and to analyze various research trends such as the actual situation. Through this, it is to find ways to improve the safety and health management system level of specialized construction companies that want to build and obtain the safety and health management system of the construction industry and specialized construction companies that are carrying out the post-assessment and extension examination after obtaining the certification.

This study focused on online game security, which has been considered relatively insignificant when compared to the online game industry's rapid growth. In this study, the state of security incidents in the Korean game industry and security solutions for such cases were examined. At first the security incidents were classified according to the type of game security infringement. Based upon this classification, this study analyzed the causes that give rise to infringement of online game security, and developed technical solutions for such cases. Finally, this study verified whether or not these technical solutions could be applied to online game sites.

Research on object detection algorithms using 2D data has already progressed to the level of commercialization and is being applied to various manufacturing industries. Object detection technology using 2D data has an effective advantage, there are technical limitations to accurate data generation and analysis. Since 2D data is two-axis data without a sense of depth, ambiguity arises when approached from a practical point of view. Advanced countries such as the United States are leading 3D data collection and research using 3D laser scanners. Existing processing and detection algorithms such as ICP and RANSAC show high accuracy, but are used as a processing speed problem in the processing of large-scale point cloud data. In this study, PointNet a representative technique for detecting objects using widely used 3D point cloud data is analyzed and described. And RandLA-Net, which overcomes the limitations of PointNet's performance and object prediction accuracy, is described a review of detection technology using point cloud data was conducted.

Many new functional materials have been studied for efficient production and storage of energy. Many new materials such as sodium-based and sulfide-based materials have been proposed for energy storage, but research on Li batteries is still dominant. Due to the influence of environmental concerns regarding nuclear energy, interest in and research on fusion power are steadily increasing. For the commercialization of nuclear fusion, a design standard based on a considerable level of physical analysis and modeling is proposed. Nevertheless, limitations of existing materials in nuclear fusion environments limit practical applications. Tritium propagation material for continuous fusion reaction is one of the core materials, and therefore research on this material is being carried out intermittently. The key material for Li-based energy storage and tritium generation is the functional material Li-M-O. In this review, a structural description of functional Li-M-O system materials and technical trends for its applications are introduced.
