Nowadays the Project Management is increasingly adapted into almost all the fields in business management processes among leading companies both in Korea and overseas. However its actual practices are rare to be found. Among the Project Life Cycle, this report covers the real cases of the PMBOK knowledge areas in NPP Architect Engineering. The areas of the Construction, Start-up and Operation will be exception of the cases. By way of analyzing the KEPCO ENC's Processes/Procedures/Systems and the ones in PMBOK Guide, this report will show the contents in the PMBOK Guide is rather practical than theoretical. Meanwhile, implications whether the conclusions of this report might be applied to other industries such as general construction, non-nuclear plants, etc. should be left behind to follow-up studies.

In existing middleware for body sensor networks, energy limitations, hardware heterogeneity, increases in node temperature, and the absence of software reusability are major problems. In this paper, we propose an event-based grid middleware component that solves these problems using distributed resources in in vivo sensor nodes. In our multi-hop communication, we use a lightweight rendezvous routing algorithm in a publish/subscribe system of event-based communication. To facilitate software reuse and application development, a modified open services gateway initiative has been implemented in our middleware architecture. We evaluated our grid middleware in a cancer treatment scenario with combined hyperthermia, chemotherapy, and radiotherapy procedures, using in vivo sensors.

Recently, there has been active research conducted on the intelligent agent in various fields. The results have been widely applied to intelligent user-friendly interfaces. In this system, we modeled, designed, and implemented an intelligent agent system that can be applied to stock and news. Some procedures such as login sequence to the web site, process to get stock information, setting stock in concern, intelligent news system module, news analysis module, and news learning module are modeled in detail and described in block diagram level. In our experiment on stock system, it showed quite a useful alarming screen avatar result and also on news system. it successfully rearranged the order of the news according to the user's preferences.

IEC 60300 series, the international standards on dependability management system are newly developed and introduced rapidly worldwide. In order to meet this situation, it is necessary to apply them to the Korean industries effectively. This requires for us to prepare in advance for the introduction of the certification system of IEC 60300. It includes the establishment of the infrastructure such as documentation of Korean Standards, introduction of test equipments and test manuals, recognition of the certification body and training of specialists etc. This paper addresses the first step for the Introduction of IEC 60300. It includes the necessity of introduction of the system, general requirements and procedures for the certification of the industries, sampling methods design and establishment of the dependability assurance system of the materials.

In recent high-speed data moderns for use over PSTN or leased line, the data compression technique based on CCITT V.42bis Recommendation is of popular use along sith CCITT V.42 error control function. A remaining concern to advanced-application users is the protection against unintended eavesdropping. This paper proposes the architectural model on how the security mechanism should be adopted into the above mentioned error-correction/data compression moderns. Also, the functional definitions and the operational procedures are described in detail for possible implementation.

This paper demonstrates the reconstruction of input signals from only the measured signal for the simulation and endurance test of automobiles. The aim of this research is concerned with input signal reconstruction using various iterative teaming algorithm under the condition of system characteristics. From a linear to nonlinear systems which provides the output signals are estimated in this algorithm which is based on the frequency domain. Our concerns are that the algorithm can assure an acceptable stability and convergence compared to the ordinary iterative learning algorithm. As a practical application, a f car model with nonlinear damper system is used to verify the restoration of input signal especially with a modified iterative loaming algorithm.

Office based injection laryngoplasty for voice and swallow disorders is increasing steadily. In recent years, the application of injection laryngoplasty is extended to inject medicine, such as cidofovir or botox. The reason why office based injection laryngoplasty is increasing in popularity is several potential advantages when compared with other procedures. It can avoid surgical scar and is easily performed with local anesthesia. However, injection can be performed in a variety of settings, depending on several factors, including the goal of the procedure, patient comfort and anatomy, and physician skill. In this article, we describe indication of injection laryngoplasty and discuss about various techniques for procedure.

General concepts and overall procedures of APMAG-Agricultural Products Marketing Analysis Model using GIS(Geographic Information System) techniques for appropriate allocation and management of agricultural products marketing facilities are introduced. In this study, modeling techniques and visual reporting skills are both emphasized. The APMAG enables to analyze the temporal and spatial flow of agricultural products marketing by the flow function that is proposed in this study. Results analyzed by proposed model for rice are displayed many different ways and show the use of the given model.

To increase dimensional accuracy of strip width, model to compensate width spread during roughing mill has been developed. To measure the amount of width spread during the production rolling more precisely, special roughing rolling procedures for the horizontal rolling and dog-bone rolling were designed in the actual production mill. From the operational data analysis, it is known that the prime factors influencing on the width spread were strip width, strip thickness, edging amount, number of pass and type of edger roll etc., Based upon the statistical analysis of rolling data, new models which can predict width spread during horizontal rolling and dog-bone rolling were developed and tested on the actual processing conditions for the reliability. The application test showed that newly developed model gave fairly accurate predictions on the width spread during roughing passes.

A needle-free injector is one of the new non-invasive players in impregnating the biological barriers. It is considered as the next phase in drug delivery and therapeutic applications. One of the major fields of application is in skin remodeling procedures. Although many studies were carried out in understanding the principle in the needle-free injection procedure, fewer studies were done with the aim of therapeutic applications. In the present study, we tried to identify key parameters that affect the jet divergence and peak stagnation pressure on the skin surface in a conventional needle-free injector for skin treatment. A summary of the working principle and effect of the key parameters are presented.
