  • 기술지도제도는 전문기술인력을 활용하여 재해율이 높은 중ㆍ소규모 현장의 건설재해를 효율적으로 관리하기 위해 정부가 간접적인 안전관리 전문제도로 도입하였다. 하지만 IMF 이후 급격히 변화된 건설현장 안전관리 체계와 재해율 증가, 지도기관 업체의 난립과 부실한 지도업무수행 등으로 기술지도제도의 실효성에 많은 문제점이 발생하고 있다. 따라서 본 연구에서는 기술지도제도의 운영 실태와 관계 법령, 설문조사 자료를 분석하여 문제점을 도출한 후 제도 운영상의 개선 방안, 지도기관의 전문성 강화 방안, 자율적인 안전관리 유도 방안으로 구분한 내실화 방안을 제시함으로써 효율적인 재해예방대책으로서 기술지도제도의 신뢰성을 제고시키는데 그 목적이 있다.

  • ECS is a control device so that the warship can perform the mission stably by controlling and monitoring the entire propulsion system. As the recent provisions of the warship, it's propelling system is complicated than past, as the demand performance and mission of the warships are diverse. In accordance with the complicated propulsion system configuration, the demand for automatic control function of the ECS is increasing for convenient and stable propulsion system control for convenient and stable. As a result, verification of ECS stability and reliability is required. In this paper, we develop an interlocking signal simulator for verifying ECS control logic and communication protocol for warship with CODLOG propulsion systems. The simulator developed was implemented to simulate a signal of gas turbine, propulsion motors, diesel generator and 11 kinds of auxiliary equipment. The reliability of ECS was verified through the ECS communication program and the I/O signal static test with the simulator.

  • Recent modeling and simulation technologies are being used in various fields, especially in the field of military simulation-based acquisition (Simulation Based Acquisition) is recognized as an essential policy. In test and evaluation phase of the SBA process, to build a simulation-based T&E(test and evaluation) environment is needed when T&E cannot be carried by real weapon system. To improve efficiency and reliability for T&E, interoperability, reusability and reliability for T&E equipments and systems are important. In this study, we propose applying simulation framework for efficienct test and applying VV&A process for reliable evaluation. We describes the characteristics of the development process, the actual test cases and the results of evaluation. Finally utilization plan and the future direction of research is described.

  • 전자상거래는 비대면(非對面) 거래로 모든 제반과정이 진행되기 때문에 상대에 대한 신뢰성의 문제가 크며, 거래 당사자와 거래 내역에 대한 입증을 해줄 인증기관이 필요하게 된다. 현재 미국의 베리사인 등 사설인증업체가 국내전자상거래 업체의 인증업무를 담당하고 있는 실정이다. 또한, 인증은 필연적으로 관련 기술의 표준화가 수반되는데 이에 대한 국내기술이 미흡하므로 국제동향을 고려한 국내인증기술의 개발이 시급하다. 특히, 글로벌 전자상거래에서는 인증기관에 대한 문제가 더욱 절실한데 문제는 어떠한 형태로 어떤 기관이 주축이 되어 인증체계를 구축하는가 하는 것이다. 현재, 인증체계는 네트워크 방식, 계층구조, 혼합형의 세가지가 논의되고 있으며, 각각의 장단점이 존재하므로 이에 대한 심도있는 논의가 필요하다. 하지만, 이들 가운데 대부분의 국가에서는 계층구조를 바탕으로 한 네트워크 방식이 주류를 이루고 있음에 주목할 필요가 있다. 이러한 체계는 국가별로 상이할 수 있지만, 문제는 글로벌 전자상거래를 활성화하기 위해서는 보다 일관된 형태의 인증체계 구축이 필요하다는 점이다. 현재까지 이와 관련한 논의는 초보적인 단계를 벗어난 실정이며, 미국 EU 등 일부국가와 UNCITRAL, OECD, ICC, WTO 등 관련 기구에서 다양한 의견을 제시하고 있는 상태이다. 이러한 문제는 단시일 내에 해결되기는 어려울 것으로 보인다. 다만, 단기적으로는 관련국가들간의 상호인증을 통한 해결이 선행될 것이며, 이를 바탕으로 글로벌 인증체계가 실현될 것으로 판단된다. 이와 관련하여 인증과 관련한 국내 시장은 출범 초기 단계로서 글로벌 인증 관련 국 내관련 법적 제도적 보완이 필요하며, 이와 아울러 인증서비스를 이용할 사이버무역업계 및 정부 관련 기관 등의 관심이 촉구된다 하겠다.

  • The systematic validation of the ITS devices' performance reliability is very important because it helps their performance reliability to be maintained in a certain level, enabling to assure the reliability of the collected data, processed data and provided information. Although the government's regulation, "Transportation Efficiency Act", which requires ITS devices to be validated, was passed in 2001, no systematic inspection and calibration procedures have been developed so far. Therefore, in this study the systematic and efficient inspection and calibration method or procedure is investigated by reviewing the similar cases and best practices in Korea and overseas and some recommendations are made.

  • The standardization of weapon system parts is one of the elements of parts management and is an important factor for reducing the cost of acquiring and maintaining a weapon system, enhancing its reliability, improving interoperability, alleviating parts obsolescence problems, improving logistics efficiency, and strengthening the military's combat readiness. This study examined how to manage parts of domestic R&D weapon systems, overseas imports weapon system parts, and various commercial parts from a standardization perspective, and to study parts management methods for standardizing parts in the future. This system was used to achieve systematic part standardization in a military weapon system. To this end, this study investigated what elements are used to standardize weapon system parts. The importance and weight of each element were calculated using the AHP (Analytic Hierarchy Process), one of the decision-making techniques, and the design stage standards using the part selection method were studied. Through this, the selection process of standard parts, which has been made according to the experience and subjective judgment of designers and personnel, was improved to propose a systematic and objective method of standardizing weapons parts.

  • As the recognition of data's value increases, the role of data repositories in managing, preserving, and utilizing data is becoming increasingly important. This study investigates ways to enhance the trustworthiness of data repositories through obtaining CoreTrustSeal (CTS) certification. Trust in data repositories is critical not only for data protection but also for building and maintaining trust between the repository and stakeholders, which in turn affects researchers' decisions on depositing and utilizing data. The study examines the CoreTrustSeal, an international certification for trustworthy data repositories, analyzing its impact on the trustworthiness and efficiency of repositories. Using the example of DataON, Korea's first CTS-certified repository operated by the Korea Institute of Science and Technology Information (KISTI), the study compares and analyzes four repositories that have obtained CTS certification. These include DataON, the Physical Oceanography Distributed Active Archive Center (PO.DAAC) from NASA, Yareta from the University of Geneva, and the DARIAH-DE repository from Germany. The research assesses how these repositories meet the mandatory requirements set by CTS and proposes strategies for improving the trustworthiness of data repositories. Key findings indicate that obtaining CTS certification involves rigorous evaluation of organizational infrastructure, digital object management, and technological aspects. The study highlights the importance of transparent data processes, robust data quality assurance, enhanced accessibility and usability, sustainability, security measures, and compliance with legal and ethical standards. By implementing these strategies, data repositories can enhance their reliability and efficiency, ultimately promoting wider data sharing and utilization in the scientific community.

  • Initial Risk assessments using physicochemical properties and acute toxicity are conducted to provide information for managers to decide the potential adverse effects and played as a tool for decision-making in development of new substances. In this study, we built initial risk assessment framework and carried out human and ecology initial risk assessment for three different pesticides of captan, glyphosate, and paraquat dichloride to confirm our framework. Two water estimation models of GENEEC (GENeric Estimated Environmental Concentration) and FOCUS (FOrum for the Co-ordination of pesticide models and their USe) were employed for pesticides exposure assessment. Application for paraquat dichloride and glyphosate uses shows very low human and ecology risk. On the other hand, high acute ecological risk was observed from the application for captan. These results showed good agreements with the U.S. EPA RED (Reregistration Eligibility Decision) reports verifying the framework of this study.
