  • The objective of the Maintenance Rule (MR) is to require monitoring of the overall continuing effectiveness of licensee maintenance programs to ensure that the safety related and certain nonsafety-related SSCs are capable of performing their intended functions. In Korea, as risk informed applications and regulation become active, the necessity of Performance Based Regulation (PBR) has increased. The objective of this article is to study the effectiveness of MR based on performance and feasibility of MR adoption at Korean Nuclear Power Plants (NPPs) for effective maintenance and regulation.

  • The study aims to supplement facility management plan and safety regulations & standard of oil pipeline by searching and reviewing related regulation & standard inside and outside of the country. Korean regulation & standard is reviewed based on harbor and fishery design standard of the ministry of maritime affairs and fisheries, general technology standard of oil pipeline safety regulation, gas excavation construction and safety maintenance indicator of Korea gas corporation. Global regulation & standard is reviewed based on U.S standard inspection for offshore pipeline and Europe/Mexico standard inspection for offshore pipeline. The contents of offshore pipeline installation is inserted into pipeline sector for objected facilities of safety inspection regulation & standard and, the standard of safety inspection for offshore pipeline is newly presented into pipeline maintenance part of the planning facilities management with its inspection period and method.

  • Purpose: This article provides the efficiency test results of conducting depot maintenance. Method: ANOVA (analysis of variance) and ANCOVA (analysis of covariance) tests are conducted using data obtained from Defense Logistics Integrated Information System (DELIIS). Results: The result shows that although the effect of the depot maintenance is significant, some parts do not follow the overall effect of the depot maintenance. In order to solve the problem we provide some suggestions to be improved. Conclusion: For improving the combat readiness condition of K-1 main battle tank, the maintenance policies and regulation must be revised for the parts of the weakness. In addition, the collection way of the operation and maintenance data must be redesigned.

  • Latest development of ICT makes building, including houses, factories and public facilities, more intelligent and automatized. It follows that a wide variety of electric and ICT installations are adopted along with micro electronic equipments. Corresponding to such changes, the frequency of lightning increases due to the abnormal climate. The major damage by lightning surge is disconnection and malfunction of facilities. It is necessary, therefore, to make a regulation of inspection and maintenance for lightning protection facilities. This paper deals with main issues of a regulation draft of inspection and maintenance for lightning protection facilities based on IEC 62305

  • In this paper, reviews and analyses of literatures related to characteristics and status of disaster occurrence in steep slopes in Korea, its maintenance and regulations and laws about maintenance of slopes in abroad were carried out to propose the measures of regulation reform for disaster reduction in steep slopes. The regulation on disaster prevention in steep slopes (National Emergency Management Agency, 2007), the most effective and systematically arranged regulation out of the currently practicing regulations, was introduced to understand the overall and contents of this regulation. Therefore, problems related to disaster reduction in steep slopes from institutional, technical and financial points of view respectively were raised and their improving measures were proposed to treat the problems effectively and actively.

  • Tankyrases are multifunctional poly (ADP-ribose) polymerases that regulate a variety of cellular processes including WNT signaling, telomere maintenance, regulation of mitosis, and many others. Tankyrases interact with target proteins and regulate their interactions and stability through poly (ADP-ribosyl) ation. In addition to their roles in telomere maintenance and regulation of mitosis, tankyrase proteins regulate tumor suppressors such as AXIN, PTEN, and AMOT. Therefore, tankyrases can be effective targets for cancer treatment. Tankyrase inhibitors could affect a variety of pathways that are carcinogenic (essential for the unlimited proliferation of human cancer cells), including WNT, AKT, YAP, telomere maintenance, and regulation of mitosis. Recently, new aspects of the function and mechanism of tankyrases have been reported and several tankyrase inhibitors have been identified. Also, it has been proposed that the combination of conventional chemotherapy agents with tankyrase inhibitors may have synergistic anti-cancer effects. Based on this, it is expected that more advanced and improved tankyrase inhibitors will be developed, enabling new therapeutic strategies against cancer and other tankyrase linked diseases. This review discusses tankyrase function and the role of tankyrase inhibitors in the treatment of cancer.

  • The automatic tensioning device of the catenary system constantly maintains the tension of the trolley wire by absorbing the variations due to the elasticity of the line caused by temperature variation. The tension plays an important role in affecting the electric motorcar operation directly. This paper suggests the methodology of the life cycle extension and the maintenance of the automatic tensioning device by means of performance diagnosis of the pulley type automatic tensioning device which has been commonly used for the electric railway system. Through conducting performance diagnosis and comparative test for the wornout pulley type automatic tensioning device by replacing the components such as the bearing and the bearing shaft without replacing all the assembly, the tensioning device is analyzed whether it is properly functioned. Provided that the maintenance regulation is reinforced so as to implement the bearing replacement through periodical precise inspection along with random check-up inspection which is now carried out by the operating organizations, it is ensured that the life cycle extension and the reduction of maintenance cost of the tensioning device could be achieved.
