In the early 1960s, US Air Force lost missile launch bases during ICBM development by a defect in the missile design and operation plan. U.S. DoD realized the limitation of the existing accident prevention method. Therefore, the weapon development required system safety activity, and procurement projects of U.S. DoD applied MIL-STD-882(System Safety). Development projects of U.S. DoD more emphasized the importance of system safety after the space shuttle Challenger exploded in 1986. Currently, Airworthiness certification for military aircraft uses system safety to minimize accidents. The domestic defense aviation R&D projects also use the system safety for the airworthiness certification. However, non-aviation weapon R&D projects rarely applied system safety. This paper presents a system safety application method for domestic weapon R&D projects by studying the U.S. military standards/organizations and domestic defense aviation projects.

공급사 관계 관리 시스템은 기업 내 조달 프로세스의 효율화를 위해 중요하다. 이미 개발된 공급사 관계 관리 시스템이 있지만, 이들은 공급사 관계 관리 시스템을 도입하고자 하는 기업에게 구매 프로세스와 시스템의 변경을 요구하여 기업의 입장에서 이를 쉽게 수용하지 못하게 한다. 이를 해결하기 위해 본 논문에서는 기업의 구매 프로세스와 시스템의 변경을 최소화 할 수 있는 단순한 시스템 구조를 제안하고, 동시에 변경을 최소화하기 위하여 공급사 관계 관리 시스템의 필수 기능을 정의하고 이를 구현함을 보인다. 시장 변화에 따른 효율적 공급사 평가를 위해서 본 연구 수행에 앞선 연구 결과로 구매 과정에서 발생하는 공급사 평가를 위한 의사 결정 지원 시스템인 BestChoice가 가지는 공급사 평가 알고리즘과 공급사 평가에 대한 효율적 분석 지원을 위한 시각적 분석 방법을 도입하였다. 이와 합께 템플릿 기반 세분화 기법을 도입하여 시장 변화에 따른 공급사의 세분화를 쉽게 하여 공급사 평가 및 관리 정책의 변화를 자유롭게 하였다. 실재 구매 대행 기업에 본 연구 결과를 적용한 공급사 관계 관리 시스템을 구축함으로써 구매 프로세스나 시스템의 변경 없이 쉽게 시스템 도입이 이루어질 수 있음을 보였다.

Purpose: The purpose of this study is to research the revision efficiency of the referenced specifications/standards for raw and subsidiary materials in the field of national defense. Methods: Firstly, it was carried out to investigate the all of the Korean military drawings and establish the database for specifications/standards referenced in the field of national defense. Secondly, it was reviewed the validity of referenced specifications/standards of raw and subsidiary materials. Finally, proposal documents were made for invalid referenced specifications/standards of raw and subsidiary materials in order to suggest alternative specifications/standards. Results: All of the specifications/standards referenced in the Korean military drawings were 11,924 kinds and raw and subsidiary specifications/standards were 2,711 kinds. The proposal documents for revision of invalid referenced specifications/standards were suggested and approved by the military procurement standardization committee of DAPA (Defense Acquisition Program Administration). Therefore, the revision process of 472 kinds of referenced specifications/standards and 160,177 papers of the Korean military drawings were finished. Conclusion: Based on the results of this investigation, it could be significantly reduce to administrative costs and efforts through revision of referenced specifications/standards instead of conventional engineering change.

The purpose of this study is to suggest ways to improve the transparency of occupational safety and health management cost (OSHMC) in order to create a safe working environment that can guarantee the health of construction workers. It was performed in the following procedures and methods. (1) collecting and analyzing resources related to the OSHMC in construction, (2) gathering stakeholder opinions for interviewing actual conditions, (3) deriving the improvement plans based on survey results and (4) suggesting direction for improvement of related laws based on the results of the research. As a result of this study, the following ways were found to be effective for enhancing transparency of the OSHMC in construction. (1) disclosure of usage details in sites, (2) Expansion of the standard for the OSHMC in construction, (3) Increase in fines for false use, (4) Establishment of the plan to improve the OSHMC ratio of small-scale construction sites, (5) Strengthen the role of supervisory and support organizations such as the Ministry of Employment and Labor and the Korea Occupational Safety & Health Agency. The result of this study is expected to be used as a basic data for future improvement of the occupational safety and health acts in Korea.

Korean industry has achieved dramatic growth in a short time through continuous technical innovations. However, safety consciousness and management have not kept pace with industry growth. The characteristics of industrial accidents in socio-technical systems have become so complicated that it has been challenging for safety professionals to implement effective preventive measures because it is difficult to determine what is happening in the complex workplace. Thus far, they have focused on technical improvements and the requirements of OSH regulations to avoid legal responsibility. Accordingly, this study has used the systemic analysis method to explain the emergence of something unexpected in complex and multi-layered business structures, which is usually related to the variabilities of humans and organizations. This study chose a shipyard where a few fatal accidents had occurred because the shipbuilding industry includes numerous variabilities, including obtaining orders, manpower supply, procurement, etc. Systemic analysis progressed using FRAM based on two accident cases related to the truss platform used in LNG vessels. The outcome shows that each function within the system has its variabilities and has become coupled or dependent on other functions, increasing the possibility of accidents. This analysis method can provide OSH professionals with practical techniques for explaining what is happening in a complex socio-technical system and how to take proper measures.

In this study, the core competencies of 7-Eleven, Japan's representative convenience store, were derived through a qualitative analysis method using VRIO (value, rarity, Imitability, and organization) framework, a management strategy model based on Resource-Based View (RBV). As a result of VRIO analysis, the value can be based on the scale that 7-Eleven ranks first in the Japanese convenience store industry in terms of the number of stores and market share that it has developed based on capital. The rarity is based on the fact that raw material procurement, the main activity of a company, is establishing the nation's largest distribution channel in the entire process, from producers to logisticians and franchisees. The difficulty for Imitability is based on a dominant strategy and has secured a competitive advantage by opening stores in a specific area, improving awareness, and raising barriers to entry. As the largest company in the convenience store industry, it is confirmed that 7-Eleven is the result of organizational power that has built stores not only in Korea but also in 16 countries around the world.

Background: This retrospective study analyzed the causes of failure in the management process from the identification of brain-dead potential organ donors to actual donation in Korea over the past 5 years. Methods: Data of 8,120 potential brain deaths reported to the Korea Organ Donation Agency were used, including information received at the time of reporting, donation suitability evaluation performed by the coordinator after the report, and data obtained from interviews of hospital medical staff and the donor's family. Results: From January 2012 to December 2016, the total number of brain-dead potential organ donors in Korea was 8,120, of which 2,348 (28.9%) underwent organ procurement surgery with designated recipients. While the number of transplant donors has increased over time, the ratio of transplant donors to medically suitable brain-dead donors has decreased. The common causes of donation failure included donation refusal (27.6%), non-brain death (15.5%), and incompatible donation (11.6%); 104 potential donors (7.8%) were unable to donate their organs because they were not pronounced brain dead. Conclusion: The rate of successful organ donation may be increased by analyzing the major causes of failure in the brain-dead organ donation management process and engaging in various efforts to prevent such failures.
