Presented in the paper is an approach to developing an intelligent mold shop as a means to overcome the difficulties faced by mold-makers due to skill shortages and increased global competition. A machine shop where as much as of the human skills are replaced by a set of intelligent systems is called an intelligent machine shop, and an intelligent mold-making machine shop is called an intelligent mold shop(MS). By analyzing the contents of operator's skill. three intelligent S/W stations have been designed: Technical Data Processing(TDP) Station, Loading Schedule Station, and Real-time Monitoring Station. A detailed architecture of the TDP station is described, and measures of effectiveness of IMS are elaborated.

Moxibustion, which has a more than 4,000-year long history of use in East Asia, has been widely used for gynecological diseases. To investigate the effects of perineum (CV1) moxibustion on gynecological function, infertile women of childbearing age applied CV1 moxibustion for 30 days on a fixed schedule. The subjects had on average $2.4{\pm}1.1$ cases of infertility-related disabilities. After CV1 moxibustion treatment, on average, the subjects showed improvements in $1.5{\pm}1.0$ cases of their gynecological problems. In addition, 14.7% of the subjects got pregnant within $29{\pm}1.4$ days after the treatment. This result shows that application of moxibustion on the CV1 and uterus is an effective treatment for gynecological diseases and that it can improve the function of gynecologic organs.

Generally, the instrumentation scheme for urban excavation projects consist of a series of tools such as inclinometer piezometer, loadcell, tiltmeter etc. Because almost every equipments are placed along several typical lines, it is impossible to evaluate the whole behavior of structures and adjacent buildings simultaneously. With laser scanning technique developed for surveying, all visible structures are scanned in the form of 3D digital data in a time schedule as planned. It can be analysed effectively the movements for all area affected by excavation even the spots in where no instrumentation tools. Although there are some parts to be refined such as scanning error, proper analysing software, it gives many advantages for realistic instrumentation works in the near future.

This paper presents a game theory application for analyzing power transactions and market design in a deregulated energy marketplace such as PoolCo. The conventional least-cost approaches for the generation resource schedule can not exactly handle recent real-world situations. A systematic tool using game theory for the market participants is presented such that it determines the net profits through the optimal bidding strategies including the strategies for the bidding prices and bidding generations. We treat this power transaction game as incomplete information one, which means each market participants does not know other's cost function. And the demand elasticity of the energy price is considered for the realistic modeling of the deregulated marketplace.

An existing unit of power plant is considered to refurbish it for possible application of carbon capture and storage(CCS). Conceptual design of the plant includes basic considerations on the national and international situation of energy use, environmental concerns, required budget, and time schedule as well as the engineering concept of the plant. While major equipment of the recently upgraded power plant is going to be reused, a new boiler for air-oxy fired dual mode operation is to be designed. Cryogenic air separation unit is considered for optimized capacity, and combustion system accommodates flue gas recirculation with multiple cleaning and humidity removal units. The flue gas is purified for carbon dioxide separation and treatment. This paper presents the background of the project, participants, and industrial background. Proposed concept of the plant operation is discussed for the possible considerations on the engineering designs.

This study is concerned with the development of a project management system for the turnkey-based plant project, which will help the site manager to plan, control, and report the project progress. This system has been developed as one of the modules of the integrated information system for the H Heavy Industry Co. and is composed of five subsystems; project information system, drawing-material management system, process management system, project progress report system. A/S management system. it also integrates commercial project management package in order to schedule the project activities and report the project progress to the owner. The main purpose of the system is to provide project information, including drawing, material, and progress, to the site manger in the real time and to accumulate site know-how for the turnkey-based plant project.

Present CAM technology cannot provide important physical property such as cutting farce and machined surface. Thus, the selection of cutting conditions still depends on the experience of an expert or on the machining data handbook in spite of the developed CAM technology. This paper presents an advanced methodology to help the worker to determine optimum cutting condition for CHC machining that excludes the need for expertise of machining data handbook. The virtual machining system presented in this paper can simulate the real machining states such as cutting farce and machined surface error. And virtual machining system can schedule feed rate to adjust the cutting force to the reference force.

A comprehensive research effort in order to develop and disseminate modernized Korean housing (Hanok) has recently been initiated by Korean government. This large scale research project encompasses a wide spectrum of housing development including public policy, architectural plans, modules, construction materials and methods, prefabricated assemblies, automated production, construction management, and advanced information systems. For the purpose of integrating and automating the whole processes from an industry perspective, it is of great importance to develop a standard classification system and project numbering system (PNS) for the modernized Korean housing. This paper focuses on the standard classification systems and PNS for cost and schedule control. The distinct characteristics and managerial requirements were explored and embedded into the proposed classifications for modernized Hanok.

The study aimed at conducting comparative analysis of employees' job satisfaction between Korean brand restaurant and foreign's in the food service industry, and suggesting useful human resource management. As a result, the survey showed several findings; The first, workers in the Korean brand restaurant have more satisfied than foreign brand restaurant employee overall. The second, expecially employees in the Korean brand company have higher pride and vision than those of Foreign brand company in the restaurant business. The third, service staffs in the both recognized very low in the working schedule, fairness of promotion, and wage. Some implications are as followed; The first, works as a one day manager or unit manager who is one of the best employees. The second, use education & training video to increasing the communication. The third, attend in the decision making to being a part of co' and giving a motivation.

The purpose of this study is to examine the energy consumption, carbon dioxide emission & energy cost of district heating using sewage source. The annual TOE of heat pump using sewage source save 37.1 percent than city gas boiler. And annual carbon dioxide emission of heat pump cut down 41.3 percent than city gas boiler. If it charges the rate schedule for district heating to apartment resident, collected amount are 3,127,170 thousand won. As energy cost of heat pump & circulation pump are 1,378,072 thousand won. the profits are 1,749,098 thousand won. As payback period is 8.97years, applicability is low level. However, it has advantages in energy consumption, carbon dioxide emission & energy cost. Therefore, it needs to proceed through government assistance.
