This study aims to provide the results of a case study, based on the action research approach, in which an user-oriented management system for enterprise information systems operational performance is successful developed and applied. This study performs the research and summarizes the results by adopting 5-step approach of action research, i.e., diagnosing, action planning, action taking, evaluating and specifying learning. The most important lessons learned from the study include (1) operation performance measures should be established to be shared by the management and users; (2) evaluation and improvement activities should be performed continually; and (3) formula to calculate the measure should be evolved so that improvement initiatives can be identified. The results of the study are expected to provide the companies intending to develop a management system for enterprise information systems operational performance with the practical and useful information. In addition, it is expected to suggest the research results that can be utilized as a basis for future research in this area.

Postoperative management of anorectal malformation consists of colostomy management and then management after definitive surgery. Colostomy management requires attention to certain details, i. e. complete decompression of the distal limb to avoid secondary megarectosigmoid and prevention and treatment of urinary tract infections in patients with rectourethral fistula. Management after definitive surgery requires the care of catheters placed in the rectourethral fistula or cloacal defect. Prevention and treatment of various complications after definitive operation, i. e. wound infection, anal stenosis or stricture, anal mucosal prolapse, and management of functional disorders, i.e. constipation, fecal incontinence and urinary incontinence are also necessary. In this review, recent trends for the prevention and treatment of the above mentioned problems after operation for anorectal malformation are presented.

To help the corporations ensure more efficient production management, the Enterprise Resource Planning (ERP) system has been introduced in operation, together with a variety of approaches to make improvements in terms of quality and productivity issues. Yet, with the different types of ERP systems in operation, many companies are going through many difficulties not only in having greatly reduced work efficiency but also in making prompt decisions from the entire group-based integrated information. In this study, the analysis was made on their own ERP systems and working processes operated by a company running the multiple number of productions from the domestic and the overseas suppliers, in order to support their interacted work flow regarding their products and help improve the work efficiency by establishing standardized ERP system. Through this, it is expected to ensure more competitive system in operation by securing the flexibility in the production as well as efficient resource distribution under the corporate context of cost reduction and quality improvement.

Nuclear power plants(NPPs) are consisted of power production functions and safety functions preventing leakage of radiation. Operators working in NPPs shall maintain these functions during an operation period through various activities such as improvement & modification, corrective maintenance, preventive maintenance and surveillance test. According to the performance of these work activities, there are configuration changes in NPPs systems. Its changes cause the increase of safety risks(CDF) and plant trip risks. Recently, the importance of risk management is increasing gradually in the operation process of NPPs. Therefore, this paper presents the work management methods using the various risk monitoring systems during power operation and overhaul period. Also this paper suggests the optimum application ways of risk systems for work management.

With the development of advanced technology, automation of agricultural work is spreading. In association with the 4th industrial revolution-based technology, research on field smart farm technology is being actively conducted. A state-of-the-art unmanned automated agricultural production demonstration complex was established in Naju-si, Jeollanam-do. For the operation of the demonstration area platform, it is necessary to build a sophisticated, advanced, and intelligent field smart farming model. For the operation of the unmanned automated agricultural production demonstration area platform, we are building data on the growth of soybean for smart cultivated crops and conducting research to determine the optimal time for agricultural work. In order to operate an unmanned automation platform, data is collected to discover digital factors for water management immediately after planting, water management during the growing season, and determination of harvest time. A subsurface drip irrigation system was established for smart water management. Irrigation was carried out when the soil moisture was less than 20%. For effective water management, soil moisture was measured at the surface, 15cm, and 30cm depth. Vegetation indices were collected using drones to find key factors in soybean production prediction. In addition, major growth characteristics such as stem length, number of branches, number of nodes on the main stem, leaf area index, and dry weight were investigated. By discovering digital factors for effective decision-making through data construction, it is expected to greatly enhance the efficiency of the operation of the unmanned automated agricultural production demonstration area.

Railway transport of goods and passengers is effective in terms of energy conservation and travel time savings. Safety and ride quality have become important issues as train speeds have increased. Due to increased speeds, minor damage to railway structures and abnormal interactions between trains and structures have given rise to increasingly serious accidents. Therefore, structural health and operational conditions must be monitored continuously in all service environments. Currently, various health and operation management systems are being developed and these are reducing both maintenance frequency and costs associated with disassembly. In this review, major damage and malfunctions and their locations are first analyzed based on numerous references. Then advanced train health and operation management technologies are classified into wayside detection methods and advanced integrated sensor methods and their operating principle and functions are reviewed and analyzed.

본 연구에서는 재난관리에 있어서 민간 역량의 적극 활용과 현장상황 파악을 위한 신속한 영상정보 공유를 목적으로 민관협력 기반 현장영상 수집 및 활용체계를 구축하였다. 또한 2019년 태풍 내습 시 민관협력체계 실전가동 경험을 토대로 그 효과성을 검증하고 지속 운영을 위한 시사점을 도출하였다. 본 연구는 초동대응단계에서 민관협력을 통한 신속한 현장영상 수집과 공유 및 활용체계를 구축하였다는 점, 자발적 민간 참여를 통해 풍부한 인적자원 확보와 전문성을 공조할 수 있는 민관협력 모델을 제시하고, 재난관리 조직의 긍정적 인식 확산 가능성을 확인하였다는 점에 의의가 있다. 그러나 연구개발 진행단계의 실험적 시범운영 사례로 성과의 현행화 및 실용화에 한계가 있다. 또한, 지속적인 체계운영을 위해서는 조직기반, 운영체계, 교육·훈련, 업무의 정책화 등 제도적 지원방안 마련이 필요하다.

도로시설물의 수명동안 비용이 최소가 되는 최적의 건설 및 유지관리 전략을 수립하기 위해서는 시설물에 대한 체계적인 LCC분석이 이루어져야 하지만 아직 국내 건설프로젝트 중 토목시설물에 대한 LCC연구는 거의 이루어지지 못하여 이에 대한 기초적 연구 및 실적자료가 절실히 필요한 시점에 와 있다. 본 연구에서는 사례교량의 LCC분석을 통해 유지관리 실태를 파악하고, 장래 요구되는 유지관리수준과의 비교분석을 통해 적정유지관리수준을 제시함과 동시에 아직 사례가 별로 없는 교량구조물에 대한 실적 LCC 기초자료를 얻고자 하였다. 본 연구를 통해 LCC 측면에서 볼 때, (1) PSC교나 RC교에 비해 강교가 경제적임을 알 수 있었으며, (2) 향후 더욱 적극적인 유지관리가 필요한 것으로 분석되었다.

This research presents a prototype development and implementation of Decision Support System (DSS) for integrated river basin water management for the flood control. The DSS consists of Relational Database Management System, Hydrologic Data Monitoring System, Spatial Analysis Module, Spatial and Temporal Analysis for Rainfall Event Tool, Flood Forecasting Module, Real-Time Operation of Multi Reservoir System, and Dialog Module with Graphical User Interface and Graphic Display Systems. The developed DSS provides an automated process of alternative evaluation and selection within a flexible, fully integrated, interactive, centered relational database management system in a user-friendly computer environment. The river basin decision-maker for the flood control should expect that she or he could manage the flood events more effectively by fully grasping the hydrologic situation throughout the basin.
