Configuration management (CM) is the process of identifying and documenting characteristics of plant structures, systems and components (SSCs), and of ensuring that changes to these characteristics are properly assessed, approved, implemented, verified and recorded. The purpose of this study is to examine regulation and technical standards developed under different concepts and level of depth for classification of nuclear SSCs as an essential prerequisite of the CM. In this context, main contents of currently adopted NSSC Notice 2016-10 are reviewed and compared with those in recently published ANSI/ANS 58.14 and IAEA SSG-30. The technical standards were prototypically used for classification of O-rings in two nuclear systems. It is found that ANSI/ANS 58.14 results in different categories taking into account specific features while IAEA SSG-30 leads to same categorization of the O-rings. Key findings will be summarized for Korean regulatory amendment in the future.

In recent years, the widespread application of quality management and measurement reliability has put increasing emphasis on procedures for periodic instrument calibration. By optimizing calibration intervals, unnecessary calibrations can be minimized, thereby reducing costs. Moreover, optimizing intervals will improve compliance with regulatory directives while ensuring maximal compliance with reliability targets. In this paper, we present Calibration Interval Analysis Program developed using several establishment methodologies of calibration interval for measurement quality and reliability improvement. Also, we perform calibration interval analysis for some measurement instruments and analyse its results.

OTT 등 신규 서비스가 등장하고 미디어 산업의 가치사슬이 복잡한 지형을 형성하게 되면서 공정경쟁과 이용자 보호, 내용심의 등 다양한 문제들이 발생하고 있다. 그러나 네트워크의 물리적 특성과 기술적 요소로 사업자를 구분하는 기존법으로 OTT를 도입하는 문제는 과다한 규제와 산업 활성화 저해라는 측면에서 비판받고 있으며, 새로운 규제체계로의 도입은 플랫폼의 사회적 영향력에 대한 논란과 이해관계자와의 충돌로 장기적인 지연을 거듭하고 있다. 본 연구는 전문가들이 인식하는 기존법 내지 새로운 규제체계 하에서 OTT 도입을 위한 규제 근거와 기준에 대한 의견을 청취하고 이에 대한 타당성을 분석했다. 이와 같은 분석은 향후 OTT 도입 방식에 유의미한 시사점을 제공할 것으로 판단된다.

Nuclear power plants have recognized the importance of nuclear cybersecurity. Based on regulatory guidelines and security-related standards issued by regulatory agencies around the world including IAEA, NRC, and KINAC, nuclear operating organizations and related systems manufacturing organizations, design companies, and regulatory agencies are considering methods to prepare for nuclear cybersecurity. Cryptographic algorithms have to be developed and applied in order to meet nuclear cybersecurity requirements. This paper presents methodologies for validating cryptographic algorithms that should be continuously applied at the critical control system of I&C in NPPs. Through the proposed schemes, validation programs are developed in the PLC, which is a critical system of a NPP's I&C, and the validation program is verified through simulation results. Since the development of a cryptographic algorithm validation program for critical digital systems of NPPs has not been carried out, the methodologies proposed in this paper could provide guidelines for Cryptographic Module Validation Modeling for Control Systems in NPPs. In particular, among several CMVP, specific testing techniques for ECB mode-based block ciphers are introduced with program codes and validation models.

The traditional safety management method starts with the misconception that similar accidents will recur if the inappropriate behavior of the person who caused the accident is investigated and punishment is not judged. However, in modern safety management, incidents or situations occur when negative conditions latent in the system are mutually influenced and triggered. The precedent for revoking the disposition of suspension of first officer A of Eastar Jet, which won a legal lawsuit against the administrative regulatory authority, is a representative example that will serve as an opportunity for the administrative regulatory authority to break away from the punishment-oriented safety management method of the past. On the other hand, airmans and air carriers also need to have a clear understanding of flight regulations, and when judicial judgment is required, predictable and effective legal effects can be obtained by preparing clear standards for flight regulations. In addition, administrative regulatory authorities expect a change from the punishment-oriented safety management policy of the past to a systematic safety management policy.

Objectives: Among the regulations that have recently attracted a lot of social attention in Regulation on Occupational Safety and Health Standards, we would like to specifically present the reasons why even companies with strong will to comply with regulations that are not effective or entail a number of legal problems, and suggest ways to improve them. Methods: The facts were confirmed and identified through various methods such as interviews and meetings with labor inspectors who enforce the Regulation on Occupational Safety and Health Standards and safety officials at industrial sites experiencing them. Results: Due to the lack of effectiveness in Regulation on Occupational Safety and Health Standards, there are not a few areas that do not function properly as a preventive standard. Although operating the regulatory nature of punishment as an administrative guideline without basing it on Regulation on Occupational Safety and Health Standards is a direct violation of the principles of the administration of the rule of law, there are many expedient ways to replace what should be placed in this rule as just an administrative guideline. Conclusions: It should be prioritized to explicitly stipulate effective regulations within the Regulation on Occupational Safety and Health Standards. In addition, as regulations on occupational safety and health standards play a large part in preventing industrial accidents, comprehensive and practical measures are indispensable rather than fragmented and formal measures to ensure that these rules function properly in the prevention industrial accidents.

One of the main objectives of noise control act is to define and ensure application and respect of noise exposure limits. Most advanced countries have prepared a legal framework for noise limits either by national laws, ordinances or municipal by-laws. A large number of advaced countries have adopted the Leq index for the main sources of noise(road, railway, industry). The exception is aircraft noise for which regulatory practice is highly disparate. These differences in the indices adopted, the periods and areas to which regulations apply, definitions of measurement conditions and ways in which noise levels are calculated make it difficult to compare the current advanced countries standards. This study presents the current noise abatement policy of the advanced countries and proposes the improvement of the current noise abatement policy of Korea to catch up with it of the advanced countries.

One of the main objectives of noise control act is to define and ensure application and respect of noise exposure limits. Most advanced countries have prepared a legal framework for noise limits either by national laws, ordinances or municipal by-laws. A large number of advaced countries have adopted the $L_{eq}$ index for the main sources of noise (road, railway, industry). The exception is aircraft noise for which regulatory practice is highly disparate. These differences in the indices adopted, the periods and areas to which regulations apply, definitions of measurement conditions and ways in which noise levels are calculated make it difficult to compare the current advanced countries standards.

Since the time, cost and lack of regulatory information and guidance, one of the largest regulatory obstacles for an airframe manufacturer of polymer based advanced composite materials in certified aircraft applications, is to generate design allowables that will satisfy Airworthiness Regulations. In the past two decades, the design allowables used in military aircraft had been generated and applied in Korea, however the qualification of composite materials used in certifying airframe structure was not accomplished for design and demonstration of compliance to applicable airworthiness regulation. It is the intend of this paper that provide the basis of composite material qualification for small aircraft certification to the airworthiness regulation.

Korean practices in tolerance setting of pesticide residues on food crops were compiled with an effort to harmonize with international standards. Based on scientific data including historical background, limit setting protocols, adoption of ADI values, food factors, nation's body weights, and regulatory margins which are required for the setting of maximum residue limits, necessary measures to be taken by Korean regulatory authorities were proposed.
