The importance of Building Remodeling as a means to create an architectural environment capable of responding to the social, economic changes has increased more than ever. And it has become necessary to consider Environmental performance in Building remodeling. Consideration of converting buildings into Environment-Friendly Remodeling of Office Buildings makes more and more increased in our construction compatibility. This Study is intended to increase the designer' recognition of Environmental Performance Improvement in the feasibility analysis and schematic design of Office Building Remodeling and to provide Planning Data and Guidance. In this context, this study is focused on the "planning Guidance for Environmental Friendly Remodeling". Through this study, the flow of Environmental Design and Construction is elevated reaching the level in developed country.

Recently, alternative energy resources have emerged considerably due to the high oil prices and environment problems. Deep sea water that is one of the natural energy sources can be one of the attractive solutions to reduce the environment problems, and there are already a few examples in some developed countries. In this study, cooling system of deep sea water using heat exchangers of two hotels, located in near Haeundae Bay in Busan, have been analyzed on the quantity of electricity and gas use comparison between existing cooling system and deep seawater cooling system by using E-Quest simulation program. The results of the study showed that the Hotel A approximately saves 370 millions won per year, and the Hotel B saves 248 millions won per year. It means that the cooling system by using deep sea water has great worth to reduce the ratio of fuel sources.

This paper suggests the development device of Busan-Jinhae free Economic Zone(BJFEZ) to strengthen the competitiveness of the Port of Busan and promote the regional development in Busan. It deals with the securable feasibility of necessary sites and development costs and financial resources, the foreign investments figure, and the structure of the BJFEZ Authority. In addition, to evaluate the background, process, and contents of 'Special Purpose Local Government', the paper looks into the amendment proposal of 'Act on designation and management of free economic zones' suggested by the central government from the regional view of point. As proposals to promote and activate BJFEZ, it is recommended in the paper that it is required, first, to draw the detailed political methods to guarantee sound and sustainable development project and investment environment in accordance with regional characteristics prior to marketing, second, to develop and implement differentiated policy means to facilitate foreign investment, third, to strengthen specialty of the BJFEZ authority, and finally, to set up the supporting role and cooperation of both the central and local governments.

An evaluation of various radiometric methods to analyze $^{226}Ra$ in water has been employed on a set of 10 standard solutions of different concentrations in the range of $1-10Bq/L^{-1}$. The analysis was carried out using well-established procedures by means of gamma-ray, alpha-particle and liquid scintillation spectrometry. The feasibility of the various methods has been quantified in terms of relative standard error and percentage error. Correlations between the various methods have been presented and discussed. In general, good agreement was found in the results of various methodologies, which assures the accuracy of the methods and allows for the validation of instrumentation and procedures. Of the different methods adopted here, a combined procedure for the determination of $^{226}Ra$ along with $^{228}Ra$ using Quantulus 1220 ultra-low level background liquid scintillation counting gave the most accurate results.

High-frequency induction is an efficient way to heat mold surface by electromagnetic induction in a non-contact procedure. Though the induction heating has an advantage in terms of its rapid-heating capacity on the mold surface, it still has a restriction on mold temperature control due to geometric restriction of an induction coil according to the mold shape. It has been recently applied to the injection molding of thin-walled parts or micro/nano structures. For localized induction heating, an injection mold composed of ferromagnetic material and paramagnetic material is used. The electromagnetic induction concentrates on the ferromagnetic material, from which we can selectively heat for the local mold elements. The present study proposed a localized induction heating method by means of selective use of mold material. The feasibility of the proposed heating method is investigated through the comparison of experimental observations according to the mold material.

An arbitration has great strength in the sense that it is a more rapid dispute resolution than a trial, and is means of dispute settlement for an achievement of the purpose which is the improvement of the rights and interests of consumers. Because the remedy of consumers' damage currently has not worked well, discussions about consumer arbitration as a universal Alternative Dispute Resolution (ADR) is needed. The core of the ADR is not only the professionality and neutrality of an arbitrator and a mediator, but also the non-impairment of the arbitration proceeding's fairness. In addition, it also has both economic feasibility and efficiency. Furthermore, providing an institutional strategy is necessary to ensure fairness in an arbitration award.

Building costs means capital costs which include cost of land, cost of acquiring and preparing the site, construction costs, engineering fees, furnishings, cost of financing the project, and cost of management required to run and maintenance the building for use. An economic analysis is one of the most important factor to determine the project feasibility. The purpose of the this study is to analysis on the construction cost structure of steel truss stadium.

As power demand increases gradually, the call for underground transmission system increases. But it is very difficult and high in cost to construct new ducts and/or tunnels for power cables in metropolitan areas. HTS (High Temperature Superconducting) cable has the several useful characteristics such as increased power density. Therefore HTS cable can allow more power to be moved in existing ducts, which means very large economical and environmental benefits. In this paper, we investigate the status of korean power system and underground transmission system. Based on this, the feasibility study on applying 22kV class HTS cable to korean power system is carried out and then we propose the new power system configuration of metropolitan area with 22kV class HTS cable.

This study investigates the feasibility of incorporating student evaluations of peer review interactions into the course grade for an EFL writing course. The use of such evaluations offers a way to grade the process of writing more directly than using writing portfolios alone. Moreover, evaluating peer review interactions highlights the social aspect of writing, which is valuable in the current post-process climate in writing instruction. The 18 members of a semester-long EFL writing course at a Korean university were trained in peer response for one half of a semester; then performed evaluations of peer review interactions during the second half of the semester as part of their writing course. Student evaluations were examined to reveal whether any bias occurred due to relative age, gender, major, or question type. The results revealed no such biases. Therefore, it is suggested that students are capable of providing fair evaluations of peers, which means the evaluations can be factored into the course grade in order to evaluate the social aspect of the writing process.

A method to roll-over the paralyzed body by means of Functional Electrical Stimulation(FES) is considered. It is demonstrated that individual joint motions necessary for the rolling-over are realized by electrical stimulation. EMG measurements are also performed to analyze the cooperative activities of the muscles during rolling over motion in a case where an upper extremity was used. These results of two experiments using normal subjects verifies the fundamental feasibility of body control by FES.
