In this paper, we design the CORBA-based Mobile Agent Model (CMAM) which has the capability of the efficient work processing in distributed environment through sensing network traffic and searching the optimal path for migration nodes of mobile agent. In case existing mobile agent model is given various works from user, the network overhead and traffic are increased by increasing of execution module size. Also, if it happens a large quantity of traffics due to migration of nodes according to appointment of the passive host(below node) routing schedule by user, it needs much cost for node search time by traffic. Therefore, in this paper, we design a new mobile agent m()del that assures the reliability of agent's migration through dynamic act on the specific situation according to appointment of the active routing schedule and can minimize agent's work processing time through optimal path search. The proposed model assigns routing schedule of the migration nodes actively using an extended MAFFinder. Also, for decreasing overhead of network by agent's size, it separates the existing mobile agent object by mobile agent including only agent calling module and push agent with work executing module based on distributed object type of CORBA. Also, it reduces the required time for round works of mobile agent through the optimal path search of migration nodes.

Video-On-Demand (VOD) is expected to provide the user with interactive operations such as VCR functions. In particular, fast scan functions like “Fast Forward” of “Fast Backward” for a certain speedup playback are required. Since they require a significant amount of system resources, schemes to reduce bandwidth requirements for the network or disk are needed. In MPEG standard, Group-of-Pictures (GoP) is a random access unit which can be decoded independently. Since storing and transmitting a video stream based on GoP is efficient, it is practical to support fast scan functions based on GoP. In this paper, we present a dynamic transmission scheduling scheme to support fast scan functions with m-times normal playback rate for a stored video. The proposed scheme writes a transmission schedule whenever user requests a fast scan function. That is, the scheme constructs the data set to be smoothed by skipping GoPs according to a given speedup factor, and then writes the transmission schedule by applying a bandwidth smoothing. Finally, the scheme restarts the transmission of video data to a client according to the new schedule. The proposed scheme results in speeding up the playback rate by utilizing “GoP skipping”, and then reduces the computational overhead by applying a bandwidth smoothing based on GoP.

A construction supply chain needs an integrated information system, as the general contractor and subcontractors must communicate regularly with one another and share a substantial amount of information in their cooperative work. In the construction industry, supply chain management is necessary in the management of a system, including business process improvement, participant-oriented management, and the supply chain. This research proposed a supporting system and developed the prototype focusing on materials that play an important role in the supply chain. Construction projects are managed mainly through schedule management. As such, supply chain management should be linked with schedule management. The research implemented a prototype of the supporting system for construction supply chain management. The prototype was implemented in Microsoft Project using VBA, including a simulation tool based on @Risk for Project.

The purpose of this study was to investigate the most cost-effectiveness screening strategies for cervical cancer in Korea. We calculated the age-specific cervical cancer incidence rate from Korea Central Cancer Registry (2003), and then estimated the schedule sensitivity, detection probability, and screening and confirmative costs of each screening strategy based on the stochastic process (Lee and Zelen, 1998). The efficiency of the screening strategy was evaluated by incremental cost-effectiveness analysis. The most effective strategy was every 3 years pap smear test between the age of 35 and 65 years in the cervical cancer screening. The findings of this study will be helpful to evaluate efficiency of cancer screening strategies, and to provide the theoretical background of development and assessment of early detection of cancer in Korea.

EVMS(Earned Value Management System) is a project management method for analysis of current state of project and estimation of future state by the periodic tracking of schedule and value that activated by the project manager of government and contractor. Some countries, such as U.S.A and Austria, require the use of an EVMS for all major defense R&D project and many cases have proved that EVMS ensures that cost, schedule, and technical aspects of the contract are truly integrated and estimated, and actual progress of the project can be identified. However, the recent implementation of EVMS on Korean defense R&D project has shown number of challenges. In this paper, we defind the cancept of EVMS and analyzed EVMS implementation m order to conduct their problem.

The applications for considering their position and daily patterns of dementia patients have been developed in an early stage even if the older patients who have weaker or serious symptoms has increased in various forms. In this paper, we develop an android-based application which displays positions and pathways of patients on maps and provide messages in the cases of dangerous situations. Guardians need to register schedules including safe areas and personal information of their patients. This system registers behavior status categorized as normal or abnormal each position which is sent to a database. In particular, the deviation status is assigned in case the patients are not within the safe areas that their guardians registered on their schedule. The wandering status is assigned in case the patients are repeatedly passed by their pathways. This smart application contains the modules such as patient position sending, guardian and patient information, patient schedule and safe zone registration, position and behavior status registration, pathway display and message sending, and rescue request. This system sends the notification and alarm service providing normal and abnormal behavior with deviation and wandering status of patients respectively.

BIM is a rising core technology for increasing the productivity of the AEC industry, but such a paradigm shift is placing excessive demand on the practice of small medium size enterprises. BIM has many useful functions that are difficult to imagine in 2D CAD but BIM programs and the system buildup cost are too expensive. Therefore, small medium size enterprises hesitate to apply BIM in their fields. In this study, a customized 4D and 5D system was implemented using the building information generated from basic BIM tools, such as Revit, MS Project, Navisworks, and Excel VBA's customizing process to review the schedule and verify the quantities according to the schedule. Those programs are so basic in BIM circumstances, that small medium size enterprises can be equipped without burden. As a result, essential building information for 4D and 5D system implementation was investigated and its customizing process was established.

ILP(Instruction Level Parallelism) processors use code reordering algorithms to expose parallelism in a given sequential program. When applied to a loop, this algorithm produces a software-pipelined loop. In a software-pipelined loop, each iteration contains a sequence of parallel instructions that are composed of data-independent instructions collected across from several iterations. For vector loops, however the software pipelining technique can not expose the maximum parallelism because it schedules the program based only on data-dependencies. This paper proposes to schedule differently for vector loops. We develop an algorithm to detect vector loops at object code level and suggest a new vector scheduling algorithm for them. Our vector scheduling improves the performance because it can schedule not only based on data-dependencies but on loop structure or iteration conditions at the object code level. We compare the resulting schedules with those by software-pipelining techniques in the aspect of performance.
