In thls paper, a remote machine monitoring system for a vimal machine is proposed. The monltonng system is one of the core functmns of a vimd machne that provides a modeling and simulation environment for machining processes and management of the machine life cycle. The proposed system contains the modules for investigating tool wear using neural network and web-based real time process monitoring. An example implementation for tool wear and machining status monitoring is illustrated

Acting an important risk management tool for main contractors, pre-qualification has served a key marketing tool for subcontractors in various industries. Current industrial environment has required the time intensive pre-qualification ability to small and medium-size subcontractors as a matter of competitive business. In order to support the subcontractors, this paper proposes a database model for pre-qualification management system (PQMS) that automates the pre-qualification process by using information technologies. The modeling process consists of specifications for its requirements, functional modules, and a database model for the PQMS.

In these days, the technical advances and complexities have generated much of the difficulties in managing the project resources, both time and costing to accomplish the project in the most efficient manner. The project manager is frequently required to render judgements concerning the schedule and resource adjustments. This research develops an analytical model for a schedule-cost and risk analysis based on visual PERT/CPM. We used a two-step approaches ：in the step 1, a deterministic PERT/CPM model for the critical path and estimating the project time schedule and related resource planning, In the second step, we developed a heuristic model for crash and stretch out analysis based upon a time-cost trade-off associated with the crash and stretch out of the project. Computer implementation of this model is provided based on GUI-Type objective-oriented programming for the users and provided displays of all the inputs and outputs in the form of visual graphical. Also developed GUI-type program, Dongeui Visual-PERT/CPM. The results of this research will provide the project managers with an efficient management tool.

현재 애니메이션 산업의 주축이 되고 있는 3D 애니메이션은 그 기술이 발달하면서 더욱 복잡한 파이프라인과 글로벌 파트너쉽의 제작 트랜드로 인해 전문적인 제작 관리 도구의 필요성이 제기되어 왔다. 현존하는 제작 관리 도구 중 샷건(Shotgun)과 Ftrack(에프트랙)은 3D 애니메이션 제작에 가장 적합한 서비스를 제공하고 있으며, 전통적인 서류 중심의 제작 관리와 샷건이나 에프트랙을 활용한 제작 관리를 비교하였을 때 효율적인 면을 확인하였다. 샷건 등 제작관리도구를 통한 제작 관리의 장점은 인터넷이 연결된 곳이라면 시공간의 제약을 받지 않고 제작 구성원들이 직접 참여하는 의사소통이 가능하여 정보가 실시간으로 공유된다는 점, 의사소통 과정에서 이루어진 논의들과 제작 과정의 히스토리가 체계적으로 축적되어 이후 추적이 용이하다는 점, 제작 관리팀의 정보 취합 및 분석 업무에도 효율적으로 기여한다는 점 등이다. 하지만 이들 도구가 자료검색에 있어 메타데이터 방식을 사용하고 있어 데이터 구축에 노력이 많이 들며 정확성에 있어서의 한계를 가진다는 점, 또한 이들 관리도구 도입을 위한 전문 기술인력 확보가 선행되어야 한다는 점 등은 한국 스튜디오들이 관리도구를 도입하는 데에 부담을 가질 수밖에 없는 현실이다. 이에 대한 대안으로 이들 관리도구의 콘텐츠 기반 검색 방식의 도입과, 툴셋 제공보다 조금 더 확장된 기술 업무에 대한 서비스를 제안하는 바이다.

In this paper, we implemented the object scanning with nxtOSEK which is an open source platform. nxtOSEK consists of device driver of leJOS NXJ C/Assembly source code, TOPPERS/ATK(Automotive real time Kernel) and TOPPERS/JSP Real-Time Operating System source code that includes ARM7 specific porting part, and glue code make them work together. nxtOSEK can provide ANSI C by using GCC tool chain and C API and apply for real-time multi tasking features. We experimented the 3D scanning with ultra sonic and laser sensor which are made directly by laser module diode and experimented the measurement of scanning the object by knowing x, y, and z coordinates for every points that it scans. In this paper, the laser module is the dimension of $6{\times}10[mm]$ requiring 5volts/5[mW], and used the laser light of wavelength in the 650[nm] range. For detecting the object, we used the beacon detection algorithm and as the laser light swept the objects, the photodiode monitored the ambient light at interval of 10[ms] which is called a real time. We communicated the 3D scanning platform via bluetooth protocol with host platform and the results are displayed via DPlot graphic tool. And therefore we enhanced the functionality of the 3D scanner for identifying the image scanning with laser sensor modules compared to ultra sonic sensor.

As organizations have come to be more complex and diverse, management has come to spend an increasing proportion of its time and efforts in handling organization conflict. Moreover, organizational conflict problems are often not recognized until the balance of interests is destroyed or a radical organizational change such as BPR takes place. Once an organizational conflict arises, however, it reduces corporate synergy seriously, leading to organizational ineffectiveness. Therefore, it is important to identify the cause of organizational conflict in advance and resolve it based on the proper diagnosis as early as possible lest it should undermine the organizational effectiveness. We propose a method that facilitates diagnosing potential organizational conflict and determining appropriate strategy to the conflict, based on the analysis of cognitive maps. To support the application of the method in the real world context, a computerized tool is introduced. The working procedures of the method and the features of the tool are illustrated with their application to the real case of the cable TV home shopping company.

Schedule management of construction work is critical to completing construction projects within a given period of time. Many efforts have been made and multiple tools have been developed to support the management of construction projects using smart devices such as smartphones and tablet PCs. This study proposed a method for managing construction schedules via a smart device using Flash. The interactive and graphic properties of Flash enable the development of an app that can allow a field manager to manage schedules easily and efficiently. A prototype was implemented using Adobe Flex Builder, and a sample network was applied in a smartphone. It is convenient for a construction manager to manage construction schedules using the tool because Flash controls graphic components easily. In further studies, network diagrams such as CPM (Critical Path Method) should be developed and applied to the app.

Arrival management is a tool which provides efficient flow of traffic and reduces ATC workload by determining aircraft's sequence and schedules while they are in cruise phase. As a decision support tool, arrival management should advise on air traffic control service based on the understanding of human factor of its user, air traffic controller. This paper proposed a prediction model for air traffic controller sequencing strategy by analyzing the historical trajectory data. Statistical analysis is used to find how air traffic controller decides the sequence of aircraft based on the speed difference and the airspace entering time difference of aircraft. Logistic regression was applied for the proposed model and its performance was demonstrated through the comparison of the real operational data.

공사관리자는 가용자원을 최대한 합리적으로 사용하고 주어진 공사기간과 예산 범위 내에서 건설 프로젝트를 완료하기 위해 노력하며, 공사기간 내에 프로젝트를 끝내기 위해 바차트나 CPM과 같은 공정표를 활용한다. 제주지역의 소규모 건설회사나 현장에서는 건설공사를 수행하기 위한 도구로 공정관리 전문 소프트웨어보다는 엑셀을 많이 사용하는 것으로 조사되었다. 이는 엑셀이 원가와 연계하여 사용하기 편리하고 공정관리 소프트웨어를 활용할 전문가도 부족하기 때문이다. 대학은 지역의 중소규모 건설회사가 요구하는 공정관리 능력을 가진 인재를 배출하고 있지만 교육의 질적 및 양적 측면에서 다소 부족하다. 지방 국립대 건축공학의 교육과정 조사에 의하면 대부분의 학과는 공정관리과목이나 유사한 과목을 편성하고 있다. 주요 교육내용은 네트웍 공정관리기법에 대한 이해와 공정표 작성으로 이루어져 있다. 공정관리 소프트웨어에 대한 교육과 실습은 일부 대학에서만 이루어지고 있으므로 중소규모 건설현장의 공정관리 전문가를 양성하기 위해서는 바차트 활용과 전문 공정관리 소프트웨어 교육도 필요하다.

The need and concern about ecosystem are growing rapidly. However, ecosystem management systems are still in the first stage since the data are handled locally and separately. It results in the waste of money and time. In this research, we designed and implemented ecosystem management system of stream region using geographical information system(GIS) that is able to be used to manage the natural resource efficiently. It is expected to be used as a useful tool for Improvement of environment and management of ecosystem as well as recovery of natural environment.
