  • The statistics of occupational injuries and illnesses is one of the most important indicators of worker's safety and health in the field of occupational safety and health. The conventional statistics was produced without consideration of gender difference. This study was planned to investigate the difference of occupational injuries and illnesses by gender because that recently female workers was increased through the change of industrial structure such as from manufacturing dominated to service dominated structure. Statistics of occupational injuries and illnesses collected by workmen's compensation insurance system that have no information about gender composition of population. Economically active population survey was used to calculated the rate of occupational injuries and illnesses by gender. The distribution of estimated rate of occupational injuries and illnesses by industry, occupation and the type of accident were different between male and female employees, but those by the size of enterprise, age of the injured, the duration of the first recuperation, and job tenure were similar between male and female employees. This study has shown that gender sensitive approach may be applied to policy of occupational safety and health because that gender neutral perspective may not discover the fact of gender specific problems.

  • School safety in Japan in the 21st century has been directly influenced by changes in school education policy. The purpose of Japanese school education is to nurture self-reliance, cooperation, and creative humanity by promoting 'zest for life'. Reflecting this, the purpose of school safety is to strengthen survival capabilities that students can overcome in any disaster situation. The main features of Japanese school safety are as follows: 1) to emphasize ability to survive; 2) to focus on school safety role in home and community; 3) to balance between school safety and school education; 4) to emphasize school safety education through experiential and active learning; 5) to pursue safer school facilities; 6) to focus on continuous improvement through PDCA(Plan-Do-Check-Act); 7) to spread the UN safe school model. This analysis and discussion on Japanese school safety will give meaningful implications to Korea's school safety which has recently undergone dramatic changes.

  • This study examined the drivers' acceptance level of various active safety features with Korean drivers on Seoul urban and city roads. The test vehicle, 2013 Cadillac ATS, was equipped with FCA(Forward Collision Alert), LDW(Lane Departure Warning), SBZA(Side Blind Zone Alert), FRPA(Front/Rear Park Assist), RCTA(Rear Cross Traffic Alert), ACC(Adaptive Cruise Control), and AEB(Autonomous Emergency Braking). Participants had chances to run the tests on those systems in the parking lot accompanied by the 106km long stretch of predetermined route including local road and interurban highway in Seoul and Gyeonggi-do under normal traffic flowing environment. After the test, participants completed a series of questionnaires about the features they experienced. The results revealed that RCTA and SBZA systems received more favourable ratings compared to the other features in avoiding crashes. The respondents preferred sound alerts to haptic ones even though haptic warning methods were better in providing directional information.

  • Bacteriocins from lactic acid bacteria have attracted much attention in recent years because of their useful worth in increasing safety and extending shelf life of foods. These substances show an inhibitory effect against some food spoilage bacteria and food-borne pathogens. The inhibitory effect fo the bacteriocin produces by lactic acid bacteria against Listeria monocytogenes(L. monocytogenes) was examined in this study. The culture supernatants of 5 kinds of bacteria among the 10 kinds of testes lactic acid bacteria had the inhibitory activity against Listeria sp., various Gram positive and Gram negative bacteria. Bacteriocin produced by Lactobacillus plantarum(Lact. plantarum) LMG 7945 was the most active toward L. monocytogenes. Bacteriocin production of the Lact. plantarum LMG 7945 cultured on MRS broth was increased late logarithmic phase over early stationary phase. This bacteriocin was stable at heat treatment and acidic pH relatively; The activity was retained after heating at 121$^{\circ}C$ for 15min and was active in the pH range of 2~4 but was lost above pH 5.

  • In this study, we propose a new control system that effectively utilizes the interaction effect of control force through the connection of stiffness member for seismic performance enhancement of two adjacent structures equipped with active tuned mass damper (ATMD). The efficiency of the proposed control system is verified by comparing with the existing independent control system through the numerical simulations of the 10th- and 12th-story buildings. From the numerical results, it is confirmed that the proposed method can show similar or better control performance even with more economical control capacity than the existing independent control system. Another advantage is that the existing system does not exhibit the adaptive control performance in emergency of failure of one control device, whereas the proposed system can achieve successful adaptive control performance by economically and efficiently utilizing the interacting control effect through the connection member.

  • To protect press operator from the after-reach hazard, current Ministry of Labor Notification(MOLN) requires the use of a formula for calculating the safe distance away from the point of operation for locating press protective devices, Two Hand Control Devices(THCD) and Active Opto-Electronic Protective Devices(AOPD), on a power press. This formula is based on a same hand speed constant of 160cm/s. While EN standards use different hand speed constant for THCD and AOPD respectively. The objective of this study is to compare two guidelines on the hand speed constant published by MOLN and EN 692, also to propose a proper hand speed constant and validate it experimentally. As a experimental result, it could be known that hand speed constant of Ministry of Labor Notification should be improved as that of EN standards.

  • Vehicle safety device such as active headrest and rear detection system has been developing as people are interested about rear end collision more than head on or than front. However, there is no any standard or criterion in order to evaluate vehicle safety device for rear end collision. Also there is no test protocol about rear end collision in vehicle experiment. Therefore, this research developed scenario for experiment about rear end collision in vehicle experiment. Also this research evaluated dangerousness about vehicle test and fitness about re-enacting rear end collision using scenario developed using commercial software (PC-Crash) which can re-enact vehicle collision in virtual vehicle experiment. Scenario developed according to statistics from National Highway Traffic Safety Administration and German In-Depth Accident Study. Scenario has twelve cases which composed of Re-LVS (Rear end Leading Vehicle Stop), Re-LVM (Rear end Lead Vehicle Moving) and scenario for evaluation about malfunction of active headrest.

  • This study was performed to investigate the current regulatory guidances of safety and efficacy evaluation for the development and approval of stereoisomeric drugs in US, EU, Canada and Japan. The important categories for the development of stereoisomeric drugs are classified as 1) development of a single enantiomer as a new active substance 2) development of a racemate as a new active substance 3) development of a new single enantiomer from an approved racemate. The regulatory documents adopted in major countries for the safety and efficacy evaluation of stereoisomeric drugs were investigated with the focus on three major categories mentioned above. For the regulatory approval of stereoisomeric drugs in Korea, it is expected that the investigated results obtained in this study will be useful for the basic materials to ensure the safety and efficacy of stereoisomeric drugs as well as the stereochemical issues in chiral drug development in domestic pharmaceutical company.

  • The active structural control has emerged as structural safety of structures against natural loadings such as earthquake and wind loadings. Of many control algorithms, Sliding-Mode Control (SMC) can design both linear controller and nonlinear controller. The robustness against parameter variations as well as excitation uncertainties that is imparted to the SMC due to its nonlinear control action, could make SMC an attractive control algorithm when dealing with structures where the external excitation constitutes the main uncertainty in the system. This paper demonstrates experimentally the efficacy of the SMC algorithm based on the active mass driver system in reducing the response of seismically excited buildings. The SMC control strategy is verified with the experimental study on the one-story building model equipped with the active mass driver.
