Objectives: This study aimed to investigate the effect of satisfaction among convalescent hospital staff members on patient safety and quality of care after the certification of the medical institution. Methods: A survey was conducted on seven convalescent hospitals in Gwangju, South Jeolla Province, and North Jeolla Province, which were certified as medical institutions for convalescent hospitals by the end of May 2017, The study period lasted from July 24, 2017 to August 22, 2017. Results: There was a statistically significant correlation between staff member satisfaction and patient safety and quality of care (r = 0.586, p<0.001). Regression analysis showed that staff member satisfaction (${\beta}=0.531$, p<0.001) had a statistically significant effect on patient safety and quality of care and showed 46.9% explanatory power. Conclusions: The satisfaction of the convalescent hospital staff after the certification of the medical institution positively affected patient safety and quality of care.

This study conducted the questionnaire on present condition of certification, background, purpose, effect and promotion of an occupational health & safety management system which introduced in domestic from 1999'. The questionnaire was conducted with 136 companies which replied in questionnaire distributed to 193 companies which received the certification. Also, recognition improvement of managers and participation of workers are demanded, the support to subcontract companies is demanded because the disaster prevention effect of the companies which possess the support program on subcontract companies is good, and reduction in the insurance rate to companies which received certification is demanded to activate an occupational health & safety management system.

This study focuses on improving quality management system of naval ships to enhance safety. Recently, there were problems caused by the lack of quality management system when building Korea naval ships. Foreign naval ships are designed and built through certification by professional organizations in the commercial sector to reduce budget and enhance ship safety. Merchant ships are designed, built, operated and maintained by the organizations in accordance with the Ship Safety Act. When naval ships are exported, the ordering country requires the certification from the international classification to ensure the safety and reliability of ships. Through this study, as a method of improving the quality management system of naval ships, design verification, equipment certification and construction survey using expertise of the organizations are proposed when designing and building the naval ships.

Reliability of fatigue strength on Aircraft Composites(GFRP) Structures was assessed in this paper. Fatigue strength of GFRP was used through the existing fatigue test data with Monte Carlo method. The S_a-N_f curve of composites fatigue strength was assumed as normal distribution and reliability was analyzed using SSIT model. Fatigue stress was designed IAW ASTM F3114-15 with special safety factor of S_sf=1.2~2.0. Reliability was calculated by analytic method and FORM. Sensitivity for the effect of mean and standard deviation of fatigue strength as well as fatigue stability was evaluated. This result can be usefully applied to reliability and fatigue design for composite structures of light weight aircraft.

This is the study to introduce the Japanese Type Certification System for Domestic Aircraft and current status of Bilateral Aviation Safety Agreement. The study on the Japanese Type Certification System will contribute to understand our aircraft certification system and will be a reference in performing the Type Certification Project on KC-100 airplane in the Part 23 Normal Category.

The Technical Standard Order articles are the parts and appliances for which the civil aviation authority designates as it is necessary to standardize for the expedited certification process and aviation safety. TSO articles were used on the type certified aircraft as replacement parts in the early days of TSO authorization system, but those articles are widely used on the newly developed aircraft as well in these days. In this paper, we compared the differences of the TSO authorization systems between FAA and EASA, and proposed the rulemaking items to improve Korean TSO authorization system and to contribute to growth of aviation industry.

The Certification system will be able to expect that effect of marketing and the corporate image rising, if the certification body guarantees the contents of certification against industrial technical advance and safety, environment and efficiency, quality when it is suitable in the standard which is provided. The certification system where the private organization operates but recently on the legal notarization outside is disordering and the trust regarding the certification falls and the objective and gist of origin are damaged. But recently the trust of certification has fallen and the objective and gist of origin are damaged. Because the non-government certifications are disordering. Also the damage of the consumers majority occurs but it is insufficient the investigation analysis against the present condition regarding a non-government certification system and the operation actual condition. So it is necessary the actual condition where the countermeasure against hereupon is urgent. In this study, we present the operation direction of efficient against non-government certification system through investigation and the analysis.

The railway system is being converted to the computer system from the existing mechanical device, and the dependency on software is being increased rapidly. Though the size and degree of complexity of software for railway system are slower than the development speed of hardware, it is expected that the size will be grown bigger gradually and the degree of complexity will be increased also. Accordingly, the validation of reliability and safety of embedded software for railway system was started to become influential as the important issue. Accordingly, various software test and validation activities are highly recommended in the international standards related railway software. In this paper, we presented a software coding analysis tool using symbolic execution for railway system, and presented its result of implementation.

The purpose of this study is localization of safety relief valves fur Nuclear Service through technical development with overall design, fabrication, inspection, capacity certification test and functional qualification test of safety relief valves in accordance with KEPIC MN Code(or ASME Sec.III ). The safely relief valve is the important equipment used to protect the pressure vessel, the steam generator and the other pressure facility from overpressure by discharging the operating medium when the pressure of system is reaching the design pressure of the system. But we're depending on technology of the other country up to the present time. Because we don't have our own technologies, we have been spent the great time and money on installing and repairing safety relief valve at nuclear power plant. Therefore we have to achieve the development of safety relief valves for Nuclear Service with our own technologies.
