  • 본 논문에서는 도로 교통 정보설비의 유지관리를 위해 지능형으로 수행하는 원격감시제어 시스템을 제안하였다. 제안된 시스템은 국도 3호선에 설치되는 도로교통 설비에 대하여 유지관리를 수행하도록 시스템적으로 구축되어 있으며, 전송된 고장 정보는 중앙감시센터의 고장 정보 분석 알고리즘에 의해서 정보의 특성을 파악하도록 하였다. 분석 알고리즘은 신경회로망을 이용하여 다중으로 발생하는 고장정보에 대해서 지식 기반의 고장현상을 추론하도록 제안하였다. 고장 정보 분석 알고리즘의 유용성을 확인하기 위해 현장으로 실시간으로 전송되는 바이너리 신호의 패턴을 5가지 형태로 분류하여 성능을 분석하였으며, 이를 중앙감시센터에서의 유지관리용 운영환경 하에서 구현되도록 하였다.

  • As data management and analysis technology advances, there is active discussion on how to utilize data generated in construction projects. Among them, the materials produced during the supervision work are highly useful because their generation cycle and format are regulated according to relevant laws. In this study, we analyzed whether the data produced during the supervision work in the construction phase of apartment housing can be utilized for project performance management. First, this study identified key data necessary for performance management through FGI with experts in the field of apartment housing. Next, we collected supervisory data from the case project and identified whether the data was generated, its cycle, and storage format. As a result of the analysis, the supervisory data contained various information that could measure the performance of construction projects and had the advantage of standardized data. In the future, utilizing supervisory data is expected to enable effective performance management of apartment housing construction projects.

  • Supervision work deals with important data necessary for the performance management on building construction sites in accordance with the Building Act. Therefore, this study attempts to use the data from supervisory reports to measure the performance of private building projects. Performance measurement is important for systematic management. However, there are only a few cases in which performance measurement is performed because it requires strenuous efforts to collect data for measurement. First, this study derived 6 performance areas and 15 indicators through a few rounds of expert group discussions. Then, we confirmed the performance indicators with high feasibility of data collection through a survey of supervision experts. It is expected that the data of supervisory reports can measure systematically performance and assist in speedy diagnosis of private building construction sites.

  • In this paper, we have studied for development of unmanned remote supervisory system using mobile communication network, not wire network, not to be affected by space or distance. The unmanned remote supervisory system consists of data processing unit main part and measuring systems (modules part)-temperature measuring module, humidity measuring module and human body sensing module. The data processing unit to collect and process informations of each measuring module has the functions of data communication between a mobile cellular telephone and measuring systems. Each measuring module has supervisory and warning functions for a target of supervision. And then we have designed each system and evaluated accuracy and reliability of the combined total system.

  • In the highly competitive construction industry, a slight inaccuracy of estimation can easily cause the loss of a project. Erroneous experience-based cost estimates or allocations of on-site supervisory manpower often offset the profit gained from the project and may jeopardize the management processes. To counter these types of problems, we develop a model using mathematical analysis and case-based reasoning to automate the allocation of on-site supervisory manpower and estimate construction site costs. The method is founded upon laborious data collection processes and analysis by matching statistical assumptions, and is applicable to construction projects. In the modeling the costs and allocation of on-site supervisory manpower are quantified for both owners and contractors before initiating or bidding on the projects. The findings confirm that the degree of variation of the model predictions has an accuracy rate at 88.47%. Single-site construction projects can be accurately predicted and the assignment of supervisory manpower feasibly automated.

  • Purpose: This study aimed to identify the relationships of superior's leadership to supervisory trust and organizational commitment of nurses. Method: Subjects were 386 nurses in 8 general hospitals at G city and Seoul. Data were collected with self-administered questionnaires and analyzed using SAS 8.12 by applying ttest, ANOVA, Pearson correlation coefficient, and Stepwise multiple regression. Results: Superior's transformational leadership was $3.54{\pm}0.53$ and transactional leadership was $3.40{\pm}0.36$. Supervisory trust was $3.14{\pm}0.46$ and organizational commitment was $3.18{\pm}0.53$. Superior's transformational leadership was positively correlated with transactional leadership, supervisory trust and organizational commitment with each others. The level of supervisory trust and organizational commitment were different significantly by age, educational status, clinical career, position and superior's leadership level. Major factor that affect to supervisory trust and organizational commitment of nurses was transformational leadership, which had an explanation of 45.9% and 29.8%. Conclusions: The more nurses perceived the superior's transformational leadership, the higher nurses perceived supervisory trust and organizational commitment. Therefore, these variables generally screened and other factors should be analyzed. And if specified nursing intervention program which increase superior's transformational leadership will be developed, it may contribute to strengthen the effectiveness of nursing.

  • Data production systems are generally very large, distributed and complex systems used for creating advanced (mainly statistical) reports. Typically, data is gathered periodically and then subsequently aggregated and separated during numerous production steps. These production steps are arranged in a specific sequence (workflow or production chain), and can be located worldwide. Today, a need for improving and automating methods of supervision for data production systems has been recognized. Supervision in this context entails planning, monitoring and controlling data production. Two significant approaches are introduced here for improving this supervision. The first is a 'closely-coupledd' approach (meaning direct communication between production jobs and supervisory tool, informing the supervisory tod immediately about delays in production) - based upon traditional production planning methods typically used for manufacturing (goods) and adopted for working with data production. The second is a 'loosely-coupled' approach (meaning no direct communication between supervisory tool and production jobs is used) - having its origins in proven traditional project management. The supervisory tool just enquires continuously the progress of production. In both cases, dates, costs, resources, and system health information is made available to management. production operators and administrators to support a timely and smooth production of periodic data. Both approaches are theoretically described and compared. The main finding is that, both are useful, but in different cases. The main advantages of the closely coupled approach are the large production optimisation potential and a production overview in form of a job execution plan, whereas the loosely coupled method mainly supports unhindered job execution and offers a sophisticated production overview in form of a milestone schedule. Ideas for further research include investigation of other potential approaches and theoretical and practical comparison.

  • 전력시스템을 안정적이고 경제적으로 운영하기 위하여 EMS(energy management system)와 SCADA(supervisory control and data acquisition) 시스템이 사용되고 있다. EMS 내의 조류계산, 상정고장해석, 안전도해석과 같은 다양한 기능들의 신뢰성을 높이기 위해서는 정확한 데이터의 확보가 필수적이다. EMS 내에서 상태추정이 이와 같은 역할을 수행할 수 있으며, 본 논문에서는 정확한 상태추정을 위한 가관측성 해석 및 불량데이터 처리 프로그램을 개발하였다. 기본적인 알고리즘을 설명하고 사례연구를 통해 제안된 기법의 타당성을 검증하였다.
