본 연구에서는 우리나라에서 EVA의 주가변동에 대한 설명력을 실증적으로 분석함으로써 주주가치 극대화의 규범이 어느 정도로 통용되고 있는가를 고찰하였다. 이와 같이 EVA의 주가변동에 대한 설명력을 분석해봄으로써 자본자유화 이후 상대적으로 주주가치 극대화의 규범이 한국자본주의에 어느 정도 영향을 주었는지 판단할 수 있다. 실증분석의 결과를 종합해볼 때, 우리나라에서는 EVA의 주가변동에 대한 설명력이 그다지 뚜렷하지 않은 것으로 판단된다. 보다 확고한 판단을 내리기 위하여 당기 순이익과 매출액을 사용한 모형들과 서로 비교해보기도 하였지만 결과는 대동소이 하였다. 그리고 IMF 위기를 전후하여 시장에 구조적인 변화가 있었을 것이라는 전제 아래 표본기간을 위기가 발생한 시점을 기준으로 전과 후 두 기간을 구분하여 분석하기도 하였고, 산업별로 구분하여 고찰하기도 하였지만 결과는 기본적으로 동일하였다. 분석결과가 시사하는 바에 따르면 우리나라에는 아직 주주자본주의가 제대로 자리를 잡았다고 말할 수 없다. 그러나 기업들이 가치중심경영으로 패러다임을 신속하게 전환하지 못한다면 무한경쟁으로 집약되는 생존경쟁에서 결코 살아남지 못하기 때문에 기업들은 경영에 있어서 EVA를 더욱 중시하는 방향으로 전개할 것이다. 따라서 앞으로 EVA는 그 설명력을 점차 높여갈 것으로 판단된다.

Many countries are trying to reduce a greenhouse gas to step up their fight against climate change. There are many studies related to building only for reducing a greenhouse gas in construction area but studies related to reducing a comprehensive environmental load including various pollutants that affects the global environment are lacking. This study aims to analyse the characteristics of environmental load by work type for tunnel projects. Analysis showed that seven work types, including lining concrete, shotcrete, tunnel portal and open-cut tunnel work, etc., are representative works generated environmental load. These seven works represent 89.22 percent of total environmental load. In addition, comparison results of environmental load per tunnel's length by work type showed that a major factor of environmental load is caused by a tunnel portal and open-cut tunnel work with relatively short length (excavation length). And lining concrete and shotcrete work are larger than any other environmental load with tunnel's total length. It is expected that the result of this study will be used to make a estimation model for environmental load using approximate quantity survey of representative work types in the early stage of tunnel design. And it will be play a considerable role in establishing of environment management plan for sustainable infrastructure construction.

The environment has played a key role to improve the living condition and develop the industry. In building industries, we should consider the environment and mitigate the environmental affect. For mitigating the its affect, various areas of building technology have been developed and applied into filed work. In addition, the process in applying into field requires to conduct the assessment of the environmental affect and improve its applied technology. A lot of assessment methods are proposed in evaluate the building condition such as post-occupancy evaluation, life cycle management and life cycle assessment. Among these assessment methods, life cycle assessment is effectively utilized the environmental affect in building life cycle. Therefore, this paper aimed at analyzing the energy consumption and $CO_2$ emission in building life cycle, using the life cycle assessment and application of the example in apartment housing. This study shows that the maintenance and the production of building materials stage shares most of the amount of energy consumption and $CO_2$ emission and therefore plays an important role to planning the building in terms of the life cycle. Second, the other stages brings about a very small amount. It is important to decide the building shape and contents to mitigate the environmental affect in terms of material, volume, the pattern of the energy use and others.

Global warming has been hot issue world wide. Korea has been dealing with the global issue under the slogan of low carbon and green-growth such as setting national greenhouse gas (GHG) reduction targets and allocation to each industrial sector. Infrastructure construction, in which enormous social overhead capital (SOC) is input, has great role as one of the actions. Road is one of the representative infrastructure and large amount of resources is utilized in its construction, operation and maintenance stage. The estimation methodology of life cycle carbon emissions was developed and applied to a case study of highway currently under construction in this study. Also, total carbon emissions of all the highway in South Korea at present (2009) and cumulative carbon emissions from 2009 to 2020 were estimated using the results of case study.

The purpose of this research is to evaluate patient's satisfaction and clinician' knowledge level about pain, nausea, vomiting, and temperature management of patients after operation by develop an web-based evidence-based practice guideline about pain, nausea, vomiting, and temperature control after operation in order to apply the guideline operation patients. The collected data was analyzed through real number, average, standard deviation, t-test and repeated ANOVA by using SPSS/WIN 17.0 program. The study subjects showed a significant difference in the level of knowledge about pain, nausea/vomiting, and temperature control after operation and patient's satisfaction, before and after applying the web-based evidence-based practice guideline.

Recent years, the construction projects of a world-wide have changed toward integrated evaluation considering all environmental and economic aspect for ecological construction.. The object of this study is to suggest the method and system for integrated analysis VE/LCC and LCA. In order to integrate and analyze environmental and economic aspects of alternative design elements, decision maker should handle simultaneously much information such as cost, document and drawing. This study presents applicative methods of WBS for integrated management of these information. Also, this study presents a decision support system that can manage DB easily by using VE, LCC and LCA analysis module separately.

The life cycle assessment on greenhouse gas emission of reinforced concrete buildings shows that more than 70 percent of greenhouse gas that is discharged by a building is discharged in the building maintenance stage, including cooling and heating. To reduce the greenhouse gas emission, maintenance planning to minimize the energy consumption is necessary in the design stage. In this paper, two heat storage rooms are tested to save the air cooling energy of the buildings. The specimens are essentially identical, except that chamber A contained paraffin sheets as the finishing material, while the other, chamber B, served as a control. The test results show that chamber A with the paraffin sheets exhibited less temperature change than chamber B without the sheets when temperature was increased outside of the specimens. The heating energy was probably consumed in the phase change of the paraffin sheets, which can be useful for reducing energy consumption related to air cooling during the summer.

Environmental Product Life Cycle Management is an activity for defining and describing the product, process or activity environmentally. Especially, the main responsibility for the environmental impact of products lies in the design phase of product. Designers cany a heavy responsibility to determine technical, economic and ecological properties of the product. So in order to help designers, structured understanding and application of treating large amount of data and infonnation should be considered. This paper presents a methodological approach for decision supporting to build Product Life Cycle Management system and show a set of database modeling. Additionally, a key issue for databases is the quality of the provided information.

Applicability of LCA in establishing the integrated solid waste management were examined. Data were collected from current waste management system. LCA method was then applied to find environmentally sustainable waste management. The process comprises five steps : (1) collecting data, comparing the data with comprehensive urban planning as well, (2) analyzing the current waste treatment procedure leading to the database establishment, (3) LCA for the waste management system, (4) finding alternative scenarios based on the former steps, (5) establishing the optimum method in Ecopolis, best fitted to the local situation. The results and suggestions in this study are expected to yield comprehensive analysis as to current practices in waste management. More importantly it will be a valuable data in minimizing environmental burdens in connecting with living environments of Ecopolis. Information regarding the urban system and total environmental quality are expected from this study.
