This problem in this paper concerns the determination of safety stock for multi-echelon invenetory system. In this model the criterion is to minimize system safety stock subject to a service level constraint and expected annual total cost. Then, safety stock is determined by minimizing expected annual total cost and satisfying given service level. This expected annual total cost is obtained by expected total inventory holding cost plus the expected total stockout cost. Numerical example is given in a three-echelon inventory system. The results obtained by the use of the Hill Algorithm.

Purpose: This study was to examine the relationships between nurse's perception of patient safety culture and performance for safety nursing activities at rehabilitation hospitals. Methods: This study applied a descriptive research design. Participants were 194 nurses who have provided nursing services for more than 6 months at 4 rehabilitation hospitals located in B metropolitan city. Data were analyzed using descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation coefficients and multiple regression. Results: There was a positive correlation between the awareness of patient safety culture and safety nursing activity. Multivariate analysis showed that hospital work environment, experience of education, hospital climate, frequency of reported events, and marital status were significantly associated with the safety nursing activity. Overall, approximately 23.1% of total variability in the safety nursing activity could be explained by the 5 variables ($R^2=0.231$, p<.005). Conclusion: Nurses at rehabilitation hospitals are relatively positive about patient safety culture. Therefore, we need to develop safety education programs at the level of organization in order to improve patient safety through performing effective safety nursing activities in addition to increase awareness of patient safety culture among nurses. Furthermore, we need hospital's strategies at the system level for open communication and outcome reports regarding patient safety.

Fire fighter are exposed to the situations which are hard to predict due to continuous and accidental changes which hinder their fire fighting activity. As these threats of safety accident act as fear factors, they are doing insecure fire fighting activities. Therefore, as unclear and abnormal risks of working environment such as the riskiness of expansion of disaster, instability, obstacles of activities, abnormality, urgency, etc. increase, safety accidents are caused. This study analyzes the actual condition of safety and health and awareness of fire fighter who are exposed safety accidents during their fire fighting activities and utilize such result as the basis data to secure safety of fire fighter, keep efficient safety control and prevent accidents. The results of analysis are as follows. As rescue works among all fire-fighting works shows the highest emotional stabilization and the highest post-traumatic stress disorder is shown in fire sergeant level positions, and fire fighters whose working period is 10-15 years, reinforcing safety training to long-term workers is necessary. As the result of survey regarding safety awareness, the highest awareness level was shown in fire sergeant level positions, and fire fighters whose working period is over 20 years, and when it comes to operation of fire fighting equipments, fire-fighting workers and workers having 1-4 years of working period showed high safety awareness. The more serious injury in a fire fighter experienced as the first injury after working as a fire-fighter, the more cause-and-effect relationship was shown between personal physical condition and work, and it is shown as obstacles of fire fighting activities and affects to post-traumatic stress disorder. Moreover, as after-work off duty activities also affect to official disaster, systematic improvement of working environment is required. Occupational medical work compatibility evaluation considering the distinct characteristics of works to secure fire-fighter' health care together with fire-fighting capability is shown to be necessary.

It is becoming more and more important to develop safety-critical systems with special attention. Examples of the safety-critical systems include the mass transportation systems such as high speed trains, airplanes, ships and so forth. Safety critical issues can also exist in the development of atomic power plants that are attracting a great deal of attention recently as oil prices are sky-rocketing. Note that the safety-critical systems are in general large-scale and very complex for which case the effects of adopting the systems engineering (SE) approach has been quite phenomenal. Furthermore, safety-critical requirements should necessarily be realized in the design phase and be effectively maintained thereafter. In light of these comments, we have considered our approach to developing safety-critical systems to be based on the method combining the systems engineering and safety management processes. To do so, we have developed a design environment by constructing a whole life cycle model in two steps. In the first step, the integrated process model was developed by integrating the SE (ISO/IEC 15283) and systems safety (e.g., hazard analysis) activities and implemented in a computer-aided SE tool environment. The model was represented by three hierarchical levels: the life-cycle level, the process level, and the activity level. As a result, one can see from the model when and how the required SE and safety processes have to be carried out concurrently and iterately. Finally, the design environment was verified by the computer simulation.

This study is planned to investigate the compliance of small sized enterprises of under 5 employees directed by Industrial Safety and Health Act. Occupational safety regulation can be required for employer and employee to comply because that all members of workplace should be involved to protect worker's health. When all members of workplace comply with safety regulation, effectiveness of regulation will be realized as expectation. The study subject is composed of three groups as 501 employers, 501 employees of small sized enterprises of under 5 employees and 107 safety inspectors sampled by stratified random sampling for comparison. Data for analysis is collected from each sample using interview with structured questionnaires. Compliance is measured by 5 point scale composed by 8 sub items such as general perception, understanding, clearness, necessity, relevancy, implementation, penalty, and general compliance of the regulation. Among sub items of employer's compliance, the level of perception of regulation, necessity of regulation, relevancy of penalty are differentiated among three groups. The level of all 8 items of employee's compliance also differentiated among three groups. These results show that strategies for ensuring the same level of compliance among three groups will be needed through education, training and evaluation of regulation and feedback.

Manned aircraft structural design is based on structural safety factor of 1.5, and this safety factor is equivalent to a probability of failure of between 10-2 and 10-3. The target failure probability of FARs is between 10-6 and 10-9 per flight according to aircraft type. NATO released STANAG 4703 to established the airworthiness requirements for small UAV which is less than 150kg. STANAG 4703 requires the Target Level of Safety according to MTOW. The requirements of failure probability for small UAV is between 10-4 and 10-5. In this paper, requirements of airworthiness certification for small UAV were investigated and the relationship of safety factors to the probability of structural failure is analyzed to reduce measure of safety factor and structural weight of unmanned aircraft.
