The purpose of this study was to offer improvements, by deriving practical problems and suggesting ways to improve more realistic solutions in the multi-family housing management industry. This study is conducted in two ways. First, it was performed by reviewing related previous studies and clarifying major issues in the multi-family housing management. Second, it was performed by a questionnaire survey method, focused on the worker's opinions for that matters. The respondents work in an apartment in Seoul and the metropolitan area. A questionnaire distributed via e-mail, and then were collected. And questionnaire did not respond were excluded from the analysis. Finding were as follows -; first, it was possible to clarify four types regarding major issues in the multi-family housing management such as 'management system', 'housing management market conditions', 'management consciousness of resident', 'management performances'. Second, it was found that the competition was fierce in the same kind. And it was quite a high turnover rate of workers because of poor working conditions. Third, the most hard part was that the employee welfare was not good at work.

현재 국내에는 많은 ITS관련 센터가 구축또는 운영중에 있다. 그러나 대다수 센터가 구축되기까지의 과정만큼의 운영에 있어서도 적극적인 발전방안과 연구가 진행되고 있지는 못하고 있는 실정이다. 이에 센터 내 연구부서 및 전문인력의 활성화로 질적인 진화가 이루어져야 하며, 본 연구에서는 현재 구축 및 운영중인 국내외 교통관리센터 운영조직을 분석하고 직접관리 분야 및 유지관리용역 분야 등 관리주체의 문제, 운영조직의 적정규모 및 권장안을 제시하고자 한다 또한 교육체계를 활성화할 수 있는 정기 및 수시교육방안과 업무매뉴얼 작성방안도 제시하였다. 향후 이를 기반으로 많은 연구가 구체적이며 다각적으로 진행되어야 할 것이며 센터 주관기관 또는 지자체 또한 이에 대한 관심과 투자를 아끼지 말아야 할 것이다. 또한 적절치 못한 인력배치와 전면적인 위탁관리도 시스템의 성능을 저하시킬 우려가 있음을 유의해야 하며, 국내 교통관리센터 통합연구조직 등 각 시스템을 위해 보다 효율적이고 내실있는 연구를 진행할 수 있는 여건이 마련되어야 할 것이다.

최근 컨테이너선의 대형화 추세와 항만간의 경쟁 가속화로 인해 컨테이너터미널의 효율적 운영과 생산성 향상에 대한 관심과 노력이 증대되고 있다. 특히 YT를 이용한 이송방식을 채택하고 있는 터미널의 경우 AGV(Automated Guided Vehicle)를 이용하고 있는 자동화터미널에 비해 상대적으로 경제성 및 운용효율성 측면에서 불리한 것이 사실이다. 최근 10여 년간 이와 같은 YT운용의 비효율성을 보완하기 위해 YT Pooling Operation 도입과 같은 노력이 계속되어 왔으나 개별 YT의 위치인식기능부재로 인한 제약으로 실질적인 효과는 미미한 수준이었다. 본 연구에서는 최근 주목받고 있는 RTLS(Real Time Location System) 기술을 활용하여 기존 YT Pooling Operation의 제약사항을 해결하는 새로운 개념의 YT Dynamic Operation 모델을 세안한다.

A company needs low cost and high efficient S/W tools to improve the white color productivity in daily operation, These needs may be satisfied by end-user knowledge management system to be suggested in this paper. We suggest that the end-user knowledge management is not made by specialized developer but directly made by end-users of some related managers using company-wide DB and department DB. We expect that this end-user knowledge management system will increase the efficiency of end-user daily operation and minimize the total life cycle cost of end-user computing system in industry. The suggested end-user knowledge management system has been tested in some companies through the training course.

In real-time electricity price environment, the energy management system can provide the significant advantage to the residential, commercial and industrial customers since it can reduce the electricity charge by controlling the load operation effectively in response to time-varying price. However, the earlier studies for load management mainly focus on the residential and commercial customers except for the industrial customers because most of load operations in industrial sector are intimately related with production schedule. So, it is possible that the inappropriate control of loads in industrial sector causes huge economic loss. In this paper, therefore, we propose load control algorithm for factory energy management system(F-EMS) to achieve not only minimizing the electricity charges but also maintaining production efficiency by considering characteristics of load operation and production schedule. Considering characteristics of load operation and production schedule, the proposed load control algorithm can reflect the various characteristics of specific industrial customer and control their loads within the range that the production efficiency is maintained. Simulation results show that the proposed load control algorithm for F-EMS leads to significant reduction in the electricity charges and peak power in industrial sector.

The complex and dynamic job nature and the ever-changing working environment of construction projects inevitably present uncertainties to construction operations. Identification, evaluation and control of uncertainties constitute main elements of risk management and critical tasks of project management in construction. This paper is focused on application of a simplified discrete-event simulation approach in management of schedule-overrun risks, each being the combination of the occurrence probability of an uncertain interruptive factor and its potential consequence in terms of time delay. A case study observed from a concreting operation in Hong Kong is converted into a simulation model and analyzed with an in-house-developed simulation package for demonstrating how the proposed approach can be implemented to manage multiple schedule-overrun risks on construction projects.

In this paper, we proposed new outworn aircraft management procedure. ROKAF has both good management skill and information system, AMMIS, regarding aircraft maintenance based on all kinds of aircraft's defects. To optimize and secure aircraft's operation, management of the outworn aircraft is very important for ROKAF. With respect to these outworn aircraft's defects and maintenance, we analyzed defects occurrence pattern of outworn aircraft by using AMMIS data and Market Basket Analysis, and found the specified association rules for each defect. By using these association rules, we developed new management procedure for outworn aircraft based on the results of affinity analysis. The management procedure in this paper will also be used to optimal operation and maintenance of other aircraft and weapon systems.

Distribution Management System(DMS) ienhancing distribution automation system-based operation efficiency is an optimized system by various operational applications in a distribution network. DMS employs various applications like topology reconfiguration, volt/var control, and restoration at events such as overload, voltage violation, and a fault in a distribution system. An operation efficiency to employ multi-applications as restoration with short-term load forecasting is higher than a performance by a single application; and the applications are accomplished by an operator’s control. Applications’ combination is determined by various alarm information which means critical issues in order to operate a distribution system. Thus, this paper proposes an application management system which can configure application combination, control applications depending on alarm information and check their performance condition. The proposed application management system can be customized by operator easily and have high operation efficiency and reliability because it is worked by reviewed alarm information from operator.

DESIGNIN AND OPERATION OF DIGITAL EVIDENCE MANAGEMENT SYSTEM APPLYING COMPUTER FORENSICS AND ELECTRONIC CERTIFICATION Digital evidence will be used as a term, which means the electronic form of information which is necessary to confirm or prove the factum of all kinds of behaviors committed through the devices which have data processing ability including computer. It is expected that there will be the increase of legal conflicts surrounding electronic commerce activities as well as the increase of cyber crimes, as the number of Internet users are getting bigger. In order to solve the problems of conflicts derived from electronic commerce, the factum of electronic commerce activities must be confirmed. In order to confirm the factum of electronic commerce activities, the evidence is prerequisite. Almost all evidences relating to the electronic commerce activities exist in digital form. For the reason that the digital evidence can be easily damaged and changed, special management is required to collect, analyze, and preserve the digital evidence. In order to meet this requirement, this study proposes a basic model of digital evidence management system applying computer forensics and electronic authentication.
