  • 전력량계가 기계식에서 전자식으로 변화되면서 전력량계 교체주기의 재설정이 요구되고 있다. 현재까지는 기계식 전력량계의 교체주기를 적용하여 7년으로 교체주기를 정하고 있으나 기계식과 전자식은 차이가 있으므로 전자식 전력량계의 적정한 교체주기를 결정하여야 한다. 적정한 교체주기를 결정하기 위해서는 전자식 전력량계의 수명평가가 선행되어야 한다. 본 연구에서는 전자식 전력량계의 부품 분석을 통하여 전자식 전력량계의 수명에 영향을 미칠 수 있는 부품을 선정하고, 선정된 부품에 대하여 가속수명시험을 실시하였다. 가속수명시험 결과로부터 부품들의 수명을 추정하고, 수명이 가장 짧아서 전자식 전력량계의 수명을 결정하는 부품의 종류를 확인하였다. 전력량계의 수명은 가장 짧은 수명을 갖는 부품의 수명에 의존하므로 부품들의 수명 추정 결과로부터 전력량계의 수명을 평가할 수 있었다. 또한, 수명이 가장 짧은 부품에 대하여 목표 수명 이상의 수명을 가짐을 보증하기 위한 시험기준을 설계하였다.

  • There are many studies on the project planning, project management and quality management. The cost of the new project takes only 20% of system's lifetime resource and the costs of the maintenance and infrastructure take more than 80%, so the study on the maintenance is much more important than the study on the new project. There has been many studies on the economic life cycle of the system using it's maintenance cost, but no studies on it's infrastructure cost. This paper provides how we can adapt infrastructure cost, which takes more than 40% of system's life cycle cost, to the economic life cycle of the system and its effects on the system's economic life cycle.

  • The smart factory is an important axis of the 4th industrial revolution. Smart factory is a system that induces the maximum efficiency and effectiveness of production using the IoT and intelligent sensing systems. The product lifecycle management technique is a method that can actively reflect the consumer's requirements in the smart factory and manage the entire process from the consumer to the post management. There have been many studies on product lifecycle management, but studies on how to organize product lifecycle management knowledge domains in preparation for the era of the 4th industrial revolution were insufficient. This study analyzed the opinions of a group of experts preparing for the 4th industrial revolution in terms of product lifecycle management. The impact of the 4th industrial revolution on the detailed knowledge areas of product lifecycle management was investigated. The changes in product lifecycle management were summarized using a qualitative data analysis technique for a group of experts. Based on the opinions of experts, the product lifecycle management, which consists of a total of 30 detailed knowledge areas, was prepared to supplement or prepare for the 4th industrial revolution. This study investigates changes in product lifecycle management in preparation for the 4th industrial revolution in the knowledge domain of the existing defined product life cycle management. In future research, it is necessary to redefine the knowledge domain of product life cycle management suitable for the era of the 4th industrial revolution and investigate the perception of experts. Considering the social culture and technological change factors of the 4th industrial revolution, the scope and scope of product life cycle management can be newly defined.

  • This study aims to draw implications on a life-cycle system of digital contents through a case study about EDUNET in order to maintain the quality and efficiency of the service for educational digital contents in the primary and secondary education area. To achieve the objective, lead teachers in EDUNET service participated in requirements analysis about the life-cycle of the digital contents, for example, contents utilization periods, the periods for being updated, etc. From the results, it was found that a systematic life-cycle framework should be established to re-evaluate the contents in service and provide a quality of contents, responding to consistent changes for educational environments in teaching-learning and for educational topics/directions, or according to educational content's substance such as curriculum or extra-curriculum. This study contributes to suggesting needs to implement the systematic management of contents based on a life-cycle system by analyzing user's requirements in order to provide user-friendly service for the K-12 educational digital contents.

  • In this study we analyzed factors affecting the life cycle of technology, quantified the evaluation criteria that will affect the life of the individual technologies, and finally proposed the improvements to calculate technology life cycle that the properties of individual technologies are reflected based on cited-patent life time(CLT). It is expected that the methodology proposed improves the limits of the existing standard model, presents more reasonable criteria and ease of persuasion on the results derived by appraisers, and finally gives a lot of the feasibility and the usability of technology life cycle derived by the improved method to appraisers.

  • Korean tourist areas are designated/managed in accordance with the Tourism Promotion Act. Since Taejongdae was designated as a tourist area in 1969, a total of 230 tourist areas have been designated/built/operated. It has been 46 years since the first tourist area was designated. According to the Tourism Area Life Cycle by Butler, it is estimated that the flow of the life cycle will be reflected in ups and downs over time. Thus, this study aimed to provide basic data for suggesting the direction of changes and development of the future tourist areas after analyzing the life cycle stage of domestic tourist areas, by applying the Tourism Area Life Cycle by Butler. The research method was based on the tourist areas by year, the number of visitors, and data of the target to derive the change transition curve, obtained by dividing the life cycle stages of the tourist areas based on the visitor rate of change. In the analysis results, more than 1/3 of domestic tourist areas are reaching the stagnation/decline stage, and tourist areas such as hot springs and seaside/beach resources show a particularly high ratio of stagnation/decline. The tourist areas that already have reached the stagnation/decline stage will need to analyze the causes for the decline, seek for resolution measures, and introduce new innovative elements. Even though the results of this study are not sufficient to be used as an absolute standard to decide the life cycle stage of domestic tourist areas, it is considered to be adequate for phenomenologically understanding the life cycle stage of Korean tourist areas. Based on this study, the causes for the stagnation/decline of tourist areas can be revealed while it can be also used as basic research to establish revitalization measures for tourist areas by introducing new innovation.

  • In rapidly changing educational technology and trends, services providing educational digital contents have been focused on offering new contents customized on the state-of-the-art technology and trends, rather than re-evaluating or eliminating the contents on service based on the changed topics and video quality. This study explores domestic cases about educational digital contents in order to draw implications on proper life-cycle models and effective re-evaluation periods for the quality assurance of the contents. To achieve this objective, representative services in primary-secondary, higher, and lifelong education sectors were selected, and experts in the services were participated in focused group interview. Based on the interview results, the re-evaluation process and life-cycle issues in the management of contents were analyzed according to the educational levels and the implications on the life-cycle models were drawn. This study contributes to establishing a basis for the systematic life-cycle policy of the services in order to make more sustainable management of the digital contents.

  • As the research environment, such as Open Science, has recently changed, the scope of research support services conducted by university libraries is also expanding. In particular, there is a movement that needs to develop research support services of university libraries that are suitable for this through a clear understanding of the research life cycle centering on overseas. The purpose of this study is to provide suggestions that university libraries can refer to when developing research support services that can systematically support all phases of the research life cycle. To this end, the research life cycle was divided into five stages, "planning," "project," "publishing," "preservation" and "disseminating" and the research support services provided at each stage were examined around the cases of U.S. and domestic university libraries. Based on the implications obtained from the case, a service plan was proposed for domestic university libraries to systematically support each phase of the research life cycle.
