  • Automobiles have become part of our lives in modern society. But since they can be detrimental once problems occur on the road safety requirements are stringent. In this paper DFSS procedure is applied to the establishment of headliner safety. Specifically, IDDOV is employed where problems are identified, areas for development clarified, optimization realized, and finally optimal conditions verified at the final stage.

  • A finite element method which is discontinuous in time is developed for the solution of the classical parabolic model of heat conduction problems. The approximations are continuous with respect to the space variables for each fixed time, but they admit discontinuities with respect to the time variable at each time step. The method is superior to other well-known approaches to these problems in that it allows a wider range of moving boundary value problems to be dealt with, such as are encountered in complex engineering operations like ground freezing. The method is applied to one-dimensional and two-dimensional heat conduction problems in this paper, although it could be extended to more higher dimensional problems. Several example problems are discussed and illustrated, and comparisons are made with analytical approaches where these can also be used.

  • This study is plan to show what kinds of problems we have and how we can overcome problems about occupational safety and health education and training system in Korea, Some features which advanced countries had were found and characterized as follows; First, advanced countries realized the importance of safety and health education on the role of preventing accident and they had varieties of training and education programs on the industrial safety and health for employer and worker. Second, there were many safety and health education programs and grants which especially focused to the small businesses. Third, they had also several programs to induce employer and worker's concerning about the safety and health education voluntarily, In conclusion, we introduced some inducing models, and proposed to revise contents of the education programs and to increase participation of other parties in safety and health education market so that could vitalize our safety and health education and training.

  • Due to technological development in the globalized food system, quantitative problems of food supply have been solved, but food risks have expanded from problems in specific regions to global problems. In order to maximize the efficiency of agricultural production, the growth in agricultural production system, procirement of raw materials, establishment of food processing processes and establishment of food supply chain systems are required. Control of hazards requires facility and administrative efforts. In this study, we examined the role of CSR in conjunction with food safety. Food SCM is related to food safety and correlates with the food supply chain. In terms of the triple bottom line theory, CSR is correlated with SCM and it is possible to pursue food safety through corporate CSR and SCM. In this study, it is statistically confirmed that SCM and CSR are in a positive relationship. In the impact of CSR on food safety, it has been confirmed that economic responsibility and legal responsibility take precedence over environmental responsibility and social responsibility. Based on this, we can achieve food safety through SCM and CSR, and we can decide which of CSR activities can be prioritized.

  • The mechanization of production facilities being made rapid progress, and its function being diversified and complicated for industrialized period, the relation between machine and Its operator brings about many problems which are concerned with accident. In these circumstance, the purpose of industrial safety can not be properly achieved as considered by only one side of machine or man. Therefore, it is necessary to study how to cope with the safety of man-machine system. It has to be considered in the above mentioned contents that safety management can not be attained through only technique of numerical control. The cause of accident being studied scientifically, the service of safety problems has to be systematized and operated in rational safety organization. The purpose of this thesis is to consider preventing and decreasing industrial accident from production system field by means of the improvement of worker's own safety consciousness and introducing the function of safety management to the duties of labour union.

  • As modern industrial technologies progress, critical incidents (both conventional and new) occur as well. Although majority of these safety incidents are human-related, or human factors problems, industrial systems and/or occupational safety operations are often designed without seriously considering important roles of human factors in industrial safety. The purpose of this paper is to show how a human factors approach can contribute to industrial safety. The paper introduces a systems safety concept with some useful analysis techniques for proactively preventing human-related safety problems. A behavior-based safety analysis approach to modify hyman behavior is suggested to reduce unsafe behavior and promote safe behavior. Finally, a sound human factors/ergonomics program is recommended for management to establish a hazard-free work environment. Some current and future research issues are discussed.

  • Recently, unmanned aerial vehicle, also known as drone is being used in variety of areas. Previously drones are used as military purposes. After unmanned technology went abroad to civil, drones are used as multipurpose such as hobby, business and other more. Even though drones are very useful in many areas, problems such as safety and personal privacy infringement raised new social issues. In this thesis it will analyze and suggest solutions to the social problems of personal privacy infringement which occurred by drone filming. This thesis will also suggest that new law of drone safety must legislate quickly. Drone is exploration of new filed. Varies of new technology help to grow drone industries. Drone is able to complete tasks which are impossible or very difficult to do. To constantly grow drone industries, people must have solutions for problems of drone. If people can figure out solutions problem of drone which introduced by this thesis, value of drone will grow even more.

  • Cyber-physical systems (CPSs) can solve real problems by utilizing closely connected resources in the cyber world. Most problems arise because the physical world is uncertain and unpredictable. To address this uncertainty, information pouring from numerous devices must be collected in real-time, and each interconnected device must share the information. At this time, CPS must meet timing-related techniques and strict timing constraints that can deliver accurate information within predefined deadlines in order to interact closely beyond simply connecting the cyber and physical worlds. Timing errors in safety-critical systems, such as automobiles, aviation, and medical systems, can lead to catastrophic disasters. In this paper, we classify timing problems into two types: real-time delay and synchronization problems. The results of this study can be used in the entire process of CPS system design, implementation, operation, verification, and maintenance. As a result, it can contribute to securing the safety and reliability of CPS.

  • This study investigates the working conditions of shift workers according to age group by analyzing the sixth Korean Working Conditions Survey's data. A total of 1,323 shift workers were extracted from the dataset. Three age groups (A: 20s-30s, B: 40s-50s, C: 60s and above) were statistically compared in terms of health problems, emotional hazard exposure, work-life imbalance, and satisfaction with working conditions. Elderly shift workers (those in their 60s and above) had significantly more severe health problems and work-life imbalance, greater exposure to emotional hazards, and lower satisfaction with working conditions than young shift workers (those in their 20s-50s). The study's findings reveal the characteristics of working conditions for elderly shift workers and would be useful for improving shift workers' quality of life, as well as safety and productivity in the workplace.
