The main purpose of this study was to examine the effects of servicescape on post evaluation of hospitality industry in Gyeongnam. Customers of deluxe hotels in Gyeongnam were selected for a questionnaire survey. To achieve the study objective, 253 valid questionnaires were statistically analyzed, using frequency analysis, factor, reliability analysis and regression analysis. The results of the multiple regression analysis indicated that five of servicescape factors had significant impact on customer satisfaction and customer retention. The servicescape factors partially exerted a positive influence on word-of-mouth intention. The result of the simple regression analysis also indicated that the customer satisfaction had very significant impact on customer retention and word-of-mouth intention.

In this study, performance tests, a field evaluation, and a life cycle cost (LCC) analysis for high performance coating systems were conducted to prepare a plan to reduce the cost of maintenance coating and contribute to the service life extension of steel bridges by applying high performance coatings to steel bridges that will be constructed in the future. From the deterioration models based on the field evaluation for chlorinated rubber and urethane topcoat systems, which have been applied often, the mean service lives were derived as 20.8 and 26.6 years, respectively. For the other coating systems that have not been applied in practice, the coordination factors were differentially applied with evaluation items. The most durable coating system was predicted to be thermal spray coating (TSC) primer/epoxy intermediate coat/fluoride resin topcoat, with a predicted value as long as 42.2 years. The LCC analysis indicates that partial application of high performance coating, such as TSC and fluoride resin, to specific parts vulnerable to corrosion and ultraviolet ray (UV) is more advantageous than the use of general coating systems.

본 연구는 공공공사 공기연장 시 발생하는 추가간접비의 지급개선방안에 관한 연구이다. 현장사례를 통해 공기연장 추가 간접비 미지급 원인을 분석한 결과 실비의 인정범위에 대한 다툼 및 증빙의 어려움이 있는 것으로 조사되었으며, 전문가 의견조사 실시결과 통계적 기준이 명확하다면 공기연장 추가간접비의 인정범위를 합의하는 '공기연장 사전합의 제도'를 실시할 수 있을 것으로 조사되었다. 따라서 본 연구는 다수의 현장 실비자료를 집계하여 공사프로젝트의 공종별, 공사금액별, 공사기간별 측면에서 산정하였다. 산정한 결과 공종 및 공사기간별 요인은 공사기간연장 추가간접비 발생금액에 직접적 영향을 미치는 것으로 볼 수 없으나 도급계약금액요인에 따라서는 직접적 연관성이 있는 것으로 나타났다. 이에 계약금액별 공사기간연장에 따른 추가비용인 '공기연장 표준추가간접비'를 제시하였으며, 공기연장비용 사전합의 제도를 시행하기 위한 제도적 개선방안을 제시하였다.

본 논문은 제 7차 전력수급기본계획에서 제시한 신규 원자력발전, 석탄 발전, 그리고 LNG 복합 발전의 균등화발전비용과, 고리 1호기(가압형 경수로, PWR) 및 월성 1호기(가압형 중수로, PHWR)의 계속운전 기간별(10년과 20년) 균등화발전비용을 추정하여 비교해서 원전 계속운전의 노형별 및 계속운전 기간별 경제성을 평가하였다. 균등화발전비용을 이용한 원자력 발전의 계속운전 경제성은 노형, 계속운전기간, 할인율, 이용률 등으로부터 영향을 받는다. 분석결과에 따르면 가압형 경수로(고리 1호)는 가압형 중수로(월성 1호)보다 경제성이 높다. 원자력발전의 계속운전과 다른 전원의 경제성 비교 결과를 보면 가압형 경수로(고리 1호)의 경우에 20년 계속운전이 신규 원자력 발전 및 석탄발전보다 경제적이다. 그러나 가압형 중수로(월성 1호)의 경우에 20년 계속운전은 LNG 복합 발전보다 경제적이지만, 신규 원전 및 신규 석탄발전보다 비경제적이다. 원자력발전의 계속운전에서 보면 20년 계속운전이 경제적이며, 특히 가압형 경수로는 다른 전원보다 비용효율적이다. 원자력발전의 계속운전 정책은 모든 원전을 폐로하기 보다는 안전성과 경제성을 동시에 고려하는 선별적 접근 방식이 유효하다.

This paper examines a mechanism of the Electronic Territory Expansion and the Information-oriented Society. Especially, a strategy for the territory development based on intelligence is suggested. The strategy is divided into a strategy for the domestic electronic territory and a plan for the global electronic territory. To examine the strategy and the plan, this paper is using the causal map analysis based on the System Thinking Approach. The causal map of the mechanism is characterized by a positive feedback loop. The paper has concluded that it is important to make the positive loops as a virtuous circle. It means that when a society dominates the advantageous position firstly in the field of intelligent and electronic territory, the competitiveness can grow in arithmetical progression.

Recently, the demand of construction a new hospital is apt to decrease in the rate of increase. The demand changes quantitative expansion into seeking quality of more pleasant healing environment. Special conditions should be taken into consideration when we remodeling the hospital, because it has special and complicated equipment system. Also, newly invented medical instruments cause extension and reconstruction of a building, therefore construction of hospital continued growth and variation. Hospitals of small-to-middle size are changing to correspond on patients' request under these environment. Now we have little awareness and experience about remodeling yet, and systematic research is insufficient. Therefore, this study is aiming to purpose a data of future hospital construction plan and suitable hospital remodeling's plan direction through analysis of done medium and small scale hospitals.

After the sailing of WTO setup, The opportunity of a trade range extension is provided. OECD joining the change of the domestic construction industry. In 1994, The complete opening of a construction license was allowed As a result, The number of construction companies was increased rapidly. accordingly, We are faced with the new over competition and the problem of the financial difficulty. This paper proposes the plan for the practical technology of the small and middle sized construction companies to be improved and the plan for the working environment of small and middle sized construction companies to be improved. As a method for it, This paper proposes the Losicstics System of the construction.

Recently, there has been growing interest in Gyongin Line demand estimation, because SMRT(Seoul Metropolitan Rapid Transit Corporation) Line 7 will be extended west by 9.8km from Onsu to meet the Gyongin Line at Bupyeong-gu Office. This study was designed to estimate the change of traffic demand in Gyongin Line before and after the completion year 2011, also provide against the economic loss caused by the derived demand from Gyongin Line to SMRT Line 7. In this paper we give preliminary results for the strategic plans for traffic demand estimation and train operating plan in Gyongin Line by analyzing transport performance of Seoul metropolitan subway, and an additional study on the transportation market and the urban development plan is needed for more accurate results.

Manufacturing systems like a motor production process are analyzed using simulations than numerical analyses and/or heuristic methods due to their stochastic properties. The SME(small and medium enterprise) producing automotive motors that develop CIM systems to improve production performance is focused as an application site. We analyze and understand the system exactly using layout based simulation, and then we will suggest the initial feashible production-plan dependent on the layout to overcome weak-points of the current system(i.e., high WIPs, bottle-neck processes, due-date delays and etc.). And, solutions are suggested to increase performances of SMEs producing automotive motors in this paper. The simulation model built in this study is moedlled and analyzed with fully object-oriented methodology using SiMPLE++TM according to properties of production processes of the automotive motor. And, we will introduce ways to verify the model with developed templates for reusability when new needs will be occurred such as designing a new ship, extension or rearrangement of the system, change of production-plans, receiving urgent orders, and so on.

In general, the national rail system put an emphasis on distribution planing of stations for smooth operation of transporting goods, train allocation, parking, and maintenance. Since the national rail system is operated on the ground level, it is feasible to improve various aspects of the system during its operation. On the contrary, urban rail system is operated in the limited space under the ground, and thus, improving various aspects of the system during its operation is infeasible. Specifically, the urban subway system must have a comprehensive track distribution plan because the urban subway system has to operate in a limited environment such as it operates in a much shorter time period, The subway system has to be ready for various operations and events such as trains returning in the opposite direction. parking trains that need repair, parking during night time, storing various maintenance equipments, and connections to other tracks. Furthermore, considering the future extension of tracks, a comprehensive track distribution plan is a must.
