  • Among the medical devices, medical treatments inflicting physical energy from the outside of the body to the inside or using the energy from the devices which take advantages of chemical changes of the human body require a high degree of reliability and safety. In particular, the medical treatment on the most exposed skin to the external surface in all parts of the human body will be very important. In this perspective, when you undergo skin treatment, you need to reduce all risks and to maximize the effect of treatment equipment. Therefore, the development of equipment which guarantees high therapeutic efficacy and safety is essential.

  • Recently, children's deaths are found to be mostly caused by various accidents in Korea. But it is in reality that the safety training are very roughly conducted, and even contemporarily appropriate training materials are not sufficiently furnished contrary to the increasing significance of the safety training to reduce the children's accidental risks. This study is to compare and analyze the safety training courses of domestic and overseas elementary schools and various safety training materials. This study is purposed ultimately to reduce the accidental risks of elementary school students by suggesting the future development direction. It is concluded in this study that more appropriate safety training courses and materials should be provided to train the students to habituate their safe behaviors with a view to protect the elementary school students against the accidents. In addition, the safety training should be conducted consistently by reflecting the students' characters, and the pertinent training materials should be developed for the students' spontaneous learning and for more practical preventive training.

  • Purpose: This article presents the relationship among the perceived risk of the COVID-19 pandemic, burnout, job insecurity, and employees' job performance in Vietnam. Research design, data, and methodology: The dataset included 310 samples from Vietnamese employees through the internet (Gmail, Facebook, Google form). PLS-SEM is used on Smart-PLS software. Results: Research results show that the perceived risk of COVID-19 has a positive impact on job performance and burnout. At the same time, job insecurity positively impacts burnout and has a negative impact on job performance. The distribution of resources to many jobs (both working and worrying about losing jobs) will reduce job performance. Furthermore, the study shows that workers exposed to COVID-19 risks have higher job performance. At the same time, burnout is not a factor that reduces employees' job performance. Finally, the perceived risk of COVID-19 and job insecurity have nothing to do with each other (perceived risk of COVID-19 does not affect job insecurity). These are two factors that exist independently and in parallel. Conclusions: The authors also suggest some implications in theory and practice from these research results. The implications will reduce anxiety about risks due to COVID-19 and job security for employees.

  • Metalworking fluids (MWFs) are fluids used during machining and grinding to prolong the life of the tool , carry away debris, and protect the surfaces of work pieces. These fluids reduce friction between the cutting tool and the work surface, reduce wear and galling, Protect surface characteristics, reduce surface adhesion or welding and carry away generated heat. Workers can be exposed to MWFs by inhaling aerosols (mists) and by skin contact with the fluid. Skin contact occurs by dipping the hands into the fluid, splashes, or handling workpieces coated with the fluids. The amount of mist generated (and the result ins level of exposure) depends on many factors. To reduce the potential health risks associated with occupational exposures to MWFs, it is required to establish optimum MWFs supply method and condition with minimum Quantity in all over the mechanical machining field including high speed type heavy cult ing process.

  • Background: Women make up half of the world's population, and comprise 20% of the world's one billion smokers. The aim of this study was to assess the prevalence of smoking among female medical students in comparison to female non-medical students, and to assess the importance of medical education and knowledge in decreasing the prevalence of smoking among female university students in Saudi Arabia. Method: We used a self-administered questionnaire to collect cross-sectional data from a randomly selected sample of 320 female students attending King Abdul-Aziz University, Jeddah. Medical students comprised 50% of the sample. Results: A total of 310 students (96.9%) completed and returned the questionnaire. The prevalence of smoking was higher in non-medical female students (4.2%) compared to medical female students (0.32%) (P < 0.001). Conclusion: The prevalence of smoking is low among female medical students compared to female non-medical students, presumably because of their awareness, level of education, and knowledge of the risks to health associated with smoking. Our study highlights the need for increased knowledge, health education, and awareness of the risks of smoking to reduce smoking among female university students.

  • The SPS Agreement, concluded in the Uruguay Round for the purpose of controlling SPS risks, has traditionally been recognized to maintain the narrowest scope of application compared with TBT Agreement and GATT in relation with environmental provisions. Contrary to such an understanding on the scope of the SPS Agreement, the panel in the EC-Biotech case found that the SPS Agreement extends to regulate trade-restrictive measures on Genetically Modified Organizations(GMOs) causing health and environmental risks. This expanding scope of the SPS Agreement would have substantial influence on domestic environmental regulations as well as Multilateral Environmental Agreements(MEAs). This paper discusses the consequences of an expanding ambit for the WTO SPS Agreement through the designation of a wider range of health and environmental regulations affecting trade as SPS measures. As a result, not only precautionary measures on GMO risks, but also other health and environmental measures with trade impacts, could be subject to SPS control, and consequently, the institutional rigors of the WTO regime. However, strict and literal interpretation of the SPS provisions to expand its applicable scope would cause concerns about the WTO's intervention on the purely environmental measures. Pursuing harmonized and flexible interpretation of provisions on environment-related conflicts as well as accepting precautionary principle included MEAs will contribute to reduce such kind of concerns.

  • This study was carried out to analyze water suspension in the water supply system through fault tree analysis. And quantitative factors was evaluated to minimize water suspension. Consequently the aim of this study is to build optimal planning by analyzing scenarios for water suspension. Accordingly the fault tree model makes it possible to estimate risks for water suspension, current risks is $92.23m^3/day$. The result of scenario analysis by pipe replacement, risks for water suspension was reduced $7.02m^3/day$ when replacing WD4 pipe. As a result of scenario analysis by water district connections, the amount of risk reduction is maximized when it is connecting to network pipe of D Zone. Therefore, connecting to network pipe for D Zone would be optimal to reduce risk for water suspension.

  • Risk assessment defines as the process of estimating both the probability that an event will occur and the probable magnitude of its adverse effects. Chemical or microbial risk assessment generally follows four basic steps, that is, hazard identification, exposure assessment, dose-response assessment, and risk characterization. Risk assessment provides an effective framework for determining the relative urgency of problems and the allocation of resources to reduce risks. Using the results of risk analyses, we can target prevention, reme-diation, or control effects towards areas, sources, or situations in which the greatest risk reductions can be achieved with resources available. Risk assessment is also used to explain chemical and microbial risks as well as ecosystem impacts. Moreover, this process, which allows the quantitation and comparison of diverse risks, lets risk managers utilize the maximum amount of complex information in the decision-making process. This information can also be used to weigh the cost and benefits of control options and to develop standards or treatment options.

  • Fall accident is the most frequent accident type of occupational accidents. As the age of workers increases, trip and fall accident increases more than other types of occupational accident in the middle-aged group. In this study, the gait characteristics of 25 middle-aged participants (mean ages 47.4, S.D. 5.8) were studied to analyze the trip and fall risks. The Minimum toe clearance(MTC) against the floor surface was measured in the variable conditions of gait speed by a motion capture system. In the 50s age group, the MTC decreased and the MTC tended to reduce the variation with increasing walking speed in the level walking. Therefore, the trip and fall risks for the 50s age group is higher than the 40s age group. Especially, the faster walking speed will increase the trip and fall risks even more.
