Even though there is no doubt that ERP(Enterprise Resource Planing) system is a prevailing solution for integrating corporate information, many companies still hesitate adopting ERP system because of a great deal of cost including maintenance cost. In special, unless consulting knowledge that is infused into process reengineering phase or adequately embedded in customized ERP system is upgraded on time, then we cannot guarantee the optimality of system performance. Hence, this paper aims to construct an ERP system that adapts itself to environmental changes that are issued by database and users. To do so, we adopt intelligent agent technology and Petri net theory. The agents autonomously cooperate each other to investigate databases and to find any exceptional changes and analyze how the changes will affect ERP performance. The dynamics of the agents are represented as Petri nets. The newly proposed ERP system is to make corresponding BPR processes maintain optimality. To show the feasibility of the proposed ERP maintenance system, logistics component is described as an illustrative example.

This study analyzes the relationships between soft dollar(brokerage commission) and characteristics of funds, and between brokerage commission and return on funds, using the data on equity funds of Korea from June 2008 to November 2011. The result confirms a statistically significant negative relationship between management & sales fees and brokerage commission, meaning that rather than raising management & sales fees, which could be easily recognized by investors, it is through brokerage commission, a hidden cost, which asset management firms indirectly compensate for their services. Meanwhile, the analysis on the relationship between brokerage commission and return on funds reveals that higher brokerage commissions lead to lower return on funds, meaning at least in short-term no contribution to increasing returns in the future. These results suggest the need for streamlining the system to alleviate conflicts of interest between investors and management firms in addition to effectively controlling for principal-agent problems.

Most information systems are component-based and developed by outsourcing, and developed software is maintained integrative. However, studies on cost measurement indicators and cost estimation model have not been performed sufficiently, which are foundational to enhance the productivity and efficiency of maintenance. This study suggests indicators to measure maintenance cost for component-based software and examines maintenance cost estimation model of component software by the measurement indicators suggested. In order to generate the indicators to measure the component-based maintenance cost, the previously proposed indicators are summarized comparatively. To estimate the measurement indicators of component-based software, it makes a comparison of the previously proposed indicators and arranges them. We classify the measurement indicators by how to apply according to maintenance types of component software and then we propose the cost measurement indicators. Moreover, we propose the cost estimation model according to the maintenance types of component software using the suggested measurement indicators suggested. With the suggested estimation model, a case study is performed and its validity is verified.

Recently, management of Newspaper developmet of the internet news, broadcasting and free newspapers escalated competition between newspaper companies and other media companies as well as competition among newapaper companies. This paper analyzes the efficiency of Korean Newapaper using DEA model. We evaluate the CCR-O, BCC-O efficiency, SE and RTS of 30 Newspaper. We also suggest the Newpaper which can be benchmarked based on analyzed information. The result shows that ten Nespaper whose values of CCR-O efficiency are 1, and Fourteen Nespaper whose values of BCC efficiency are 1. RTS indicates IRS of 1 firms, DRS of 16 firms and CRS of 13 firms. To variables on the effectiveness of newspaper publishing companies for the understanding and performance analysis.

The purpose of this study is to explore some policy implications for improving the faculty personnel management and their salary scheme of the Korean national universities through comparing the systems and practices of Korean national universities to those of OECD countries. The fact that many leading OECD countries in higher education arena have been taking decentralized contract-based system based on institutional autonomy and performance beyond the previous bureaucratic control model casts some significant implications for the Korean national university reform. Especially, concerning on personnel management, it is necessary to provide more flexibility in managing faculty personnel categorization and expansion of faculty quota management for faculty and to review the maintenance of faculty's legal status as civil servant. In addition, regarding the salary scheme of faculty, we suggested performance-based salary scheme with plus-sum methods, settlement of rational faculty performance evaluation system and practices, and need for some aligning efforts for changing faculty salary scheme of the national universities.

In order to analyze the effect of strengthening the disclosure of remuneration for high-paid workers among the measures to improve the governance structure of financial companies by the Financial Services Commission in 2018, this study demonstrated the compensation system, management performance, and improvement of governance for Korean financial companies from 2015 to 2020. Analysis was performed. As a result of the empirical analysis, it was found that financial companies after 2018 decreased the employee compensation disparity and the majority shareholding ratio, while the stock performance and foreign ownership ratio increased. This study has the greatest contribution in that it is the first domestic study to verify the effect of applying the so-called Say on Pay, which discloses management's remuneration and allows shareholders to check its appropriateness through voting.

도시철도유지보수체계 정보화시스템 연구에서 예방정비시스템 구축을 위해 RCM 연구를 진행하고 있으며, 특히 예방정비에서 RCM은 지난 십 수년간 정비보수(Maintenance) 분야의 관리 기법으로 다른 어느 분야의 관리 기법 보다 한층 탁월한 발전을 하고 있다. 특히, 도시철도분야는 매우 복잡한 시스템으로 유지보수에 대한 신뢰성과 효율성 및 안전성을 가장 먼저 확보하여야 한다. 이를 위해서 본 논문에서는 여러 분야에서 오랜 기간동안 운영한 결과 상당한 유익점이 있다고 증명된 신뢰도 중심 정비 (Reliability Centered Maintenance: RCM)에 대한 소개를 하면서 도시철도 시스템에 대한 적용하고자 한다.

신속한 고장복구를 통해서 정전시간을 최소화하고자 배전기동보수업무에 최신 정보통신기술을 접목하려는 시도는 많이 있었다. 그러나, 그간 GIS, GPS, Mobile 등 시스템 구현에 필요한 핵심요소기술들이 성숙되지 않은 상태였고, 무엇보다 기반 시스템으로서의 NDIS가 전제되지 않은 상태에서 설비종합 DB와의 체계적인 연계가 미비하여 사업소 확산에 어려움이 있었다. 그렇지만, 최근에 관련 정보기술(IT)의 발달과 NDIS DB구축사업이 사업소별로 추진되어 기동보수시스템이 현장업무에 적용될 환경이 충분히 조성되어 있다고 판단된다. 이러한 배경에서 이동보수차량의 위치를 GPS와 TRS망을 연계하여 실시간 관리함으로써 고장지점으로 신속히 출동시키게 하고, 현장에서는 고장접수정보와 계통구성정보 등 관련 설비정보를 이용할 수 있게 함으로써 고객서비스의 질을 높이고, 많은 비용과 노력을 기울인 GIS DB 구축자료의 활용성과 이용효율성을 극대화시킬 수 있을 것으로 기대된다.

The design concepts of in-service inspection and maintenance are very important for the reactor system design of the nuclear power plant. The strategy of in-service inspection and maintenance should be reflected in the mechanical system design for the verification of the operability of liquid metal reactor KALIMER. In this paper the fundamental approaches of the in-service inspection and maintenance of the KALIMER are established to ensure the safety and reliability of the reactor system. The general method and requirement of the in-service inspection and maintenance for the reactor system and components are proposed and described to satisfy the intents of the ASME Section XI Division 3 and the design characteristics of KALIMER.
