To efficiently respond to drastic changes in the resource supply-demand environment, and raise national resource productivity and industrial competitiveness, major advanced countries are systematically managing their resources via their governmental resource management system and infrastructure establishment. However, Korea has no policies for supporting the innovation of resource productivity. In particular, it is urgent to develop the management system for systematically managing the resource productivity of SMEs. Therefore, in this study, we suggest a technical resource management for SMEs, which is called RMSE. It can contribute to innovating the resource productivity of SMEs lacking of resource management capabilities by reviewing the policies and studies on resource management in other countries. Also, the effectiveness of RMSE is analyzed by conducting the production process diagnosis and improvement activity of SME. Consequently, RMSE can be easily applied to the target enterprise which has insufficient resource management capability. In addition, all loss of resources, such as product defects, process by-products, and so on, can be quantified in terms of cost unit, and then resource loss factors can be efficiently improved by using RMSE. Finally, RMSE is a very useful technique improving the resource productivity and economic benefits of enterprises through the reduction of raw material use and waste emissions.

정신적 그리고 육체적 측면에서 발을 사용한 컴퓨터 입력작업의 효율성 평가

The aim of this paper is to evaluate three foot-controlled mouse devices in the psychological and physical aspects. All participants conducted three types of input tasks. Input times, electromyogram and NASA-TLX values were measured during the experiments. As the foot mouse with a slipper was used, input time was shorter than that of the others. The foot mouse with a slipper required more usage of the upper-muscles of the leg than the foot mouse with two pedals. On the other hand, the foot mouse with two pedals required more usage of the lower-muscles of the leg. The NASA-TLX value as a measure of psychological fatigue was not significantly different according to the foot-controlled mouse devices. The results might contribute as a guideline for the development of foot-controlled mouse devices.

The KMS(Knowledge Management System) can be used for a wide range of cooperative, collaborative and hierarchy communities, virtual organizations and other virtual networks, to manage content, activities, interactions and workflows. With the support of KMS, users can extract and generate new knowledge, enhance, leverage and transfer knowledge in new outcomes providing new activity using new formats and interface. Industry recognizes the central importance of managing and sharing CAD data within the organization, and powerful PDM(Product Data Management) systems have been developed to address this need. A PDM system provides the visibility necessary for managing and presenting a complete BOM(Bill Of Materials). It facilitates the alignment and synchronization of all sources of BOM data, as well as all life-cycle phases, including the as-designed, as-planned, as-built and as-maintained states. Just as importantly, the PDM system should provide the change management capabilities that allow you to see the BOM before and after changes are made.

수동형 유기 발광 다이오드(PMOLED)에 대한 가속열화시험

OLED displays use organic materials that emit light when electricity is applied. OLEDs enable emissive, bright, thin, flexible and efficient displays, and are set to replace LCDs in all display applications from small displays to large TV sets. This paper presents an accelerated degradation test for passive matrix OLED (PMOLED). Temperature, humidity and voltage are selected as acceleration stresses which affect the degradation of luminous flux of PMOLED. The failure times are predicted from the exponential degradation model, where the failure is defined as 50% decrease of luminous flux from the initial one. It is assumed that the lifetime distribution of PMOLED follows Weibull distribution and general linear life-stress relationship holds. The life-stress relationship and life characteristics at use condition are estimated by analyzing the accelerated life test data. The effect for selection of degradation models is also performed.

소프트웨어 개발 환경에서 프로젝트 생산성을 고려한 CCPM의 응용 설계

이명호 ( Myeong Ho Lee )
In this paper, we propose the application CCPM(Critical Chain Project management) approach reflects the productivity of software development as an alternative to overcome the problems of software development project management. The various efforts for a successful project management is underway in most industries and are growing in importance. The CCPM has been successfully applied in the industry can be demonstrated through many examples. However, considering the difficulty chain approach to project productivity in the software development environment is a situation still insufficient research. First, the software size, the characters show that the difference in productivity between the industry from the data of the software development project is evaluated in the FP(Function Point) measurement method to be used for measuring the effort. Data is subject to analysis and secure through a screening process for the project and major industries that meet certain criteria. Since productivity is based on how to present the applications designed to establish a project buffer size difference is considered the application of the project`s production the CCPM method.

This paper demonstrates the result of Safety Integrity Level (SIL) allocation for Honam KTX Train Control System (TCS), by applying the semi-quantitative approach. TCS is defined in this paper as the set of TVM SEI, Supplementary Safety Equipment, Power Equipment, TCS Integrated Maintenance System (TIMS), and Local Control Panel (LCP). SIL allocation is performed for these constituent subsystems of TCS. Three approaches for SIL allocation being widely used in railway application are compared in terms of the conservativeness of the allocation result; qualitative, quantitative, and semi-quantitative methods. The semi-quantitative method, based on the risk matrix and the relationship between Tolerable Hazard Rate (THR) and SIL, is less pessimistic than the qualitative method, but more conservative than the quantitative method, in the sense that it utilizes more information (e.g., risk reduction factors involved in the hazard occurrence) than the qualitative method which purely depends on the configuration of Risk Graph. Based on three principles of the semi-quantitative method, the SIL allocation process is performed for the subsystems composing TCS.

한국에서의 천연자원과 지속가능성장

김병우 ( Byung Woo Kim )
Through time-series plots, we can see relatively stable trend of energy factor share and the decreasing trend of relative energy prices (to wages) in Korea. We can compromise these empirical facts with the following explanation: if elasticity of substitution between capital and energy is smaller than one (<1) in Korea, a change (decrease) in energy price can prevent income share of resources from rising in the process of economic growth. This is consistent with theoretical and empirical results that substitution between energy and capital is so difficult. From simple empirical analysis and limited information, we can carefully infer that, in the past in Korea, resource-specific innovation was performed widely. Finally, if we are to reduce the magnitude of growth drag, we should decrease energy factor share. This can be accomplished by energy-augmenting technical progress in the case of elasticity of substitution less than 1 as in Korea.

가상신호생성 및 회귀분석을 이용한 댐 모니터링 센서 이상치 검증에 관한 연구

An efficient regression-based outlier detection method has been described in this paper. Estimating a correct regression model is an important part of estimation-based outlier detection. In the conventional method, the parameter estimation of the regression model was performed using measurements among neighbor sensors. This research proposes a weighted summation approach for making a synthesized independent variable from the observed values. A reliable regression model can be estimated from the synthesized signal. Finally, accurate outlier detection can be performed using the residual analysis of the regression model. The proposed method was successfully applied in real sensor measurements in a dam.

통신산업의 공급사슬 품질비용 측정에 관한 연구

A hybrid quality costs model was applied in an upstream telecommunications supply chain and their quality cost checklists were developed to collect data from every department. Such collected data are both directly and indirectly related to the production of the particular product at a telecommunications manufacturing company. The bulk of analysis enabled to validate whether the quality costs model reflected the industry`s present situation. Both non production and production quality costs were then investigated to understand how they were distributed from the point of view of the overall organization, department and specific processes. A variety of quality cost factors were identified and classified according to the prevention, evaluation and failure. Some areas that need improving were also determined from this, and suggestions and discussion were given on how they could be improved.
