Purpose: This study was performed to identify the current status of organization and education for evidence-based nursing (EBN) among acute care hospitals in Korea. Methods: Using a questionnaire, the data were collected from 60 acute general hospitals selected conveniently from October to November in 2016. Results: The response rate was 83.3% and the mean number of beds for responded hospitals were 977.83. Responded hospitals appeared to perceive the importance of EBN, though approximately 50% of hospitals showed insufficient status for EBN. EBN project implemented in accordance with institutional support. EBN education courses have operated within hospitals and also have attended at outside courses. Conclusion: The current status of EBN organization and education have identified and it is needed to monitor continuously to activate and expand EBN in clinical settings.

Recently modular constructions are used for not only public buildings like schoolhouse, dormitories, etc. but also residential buildings or commercial buildings. Prefabricated modular housing is a construction method that after 70~90% production of all processes at a factory, assembling and finishing construction works are conducted at sites. The construction elements of modular unit are assembled by welding and bolts using metal frames and studs. So this structure has many problems which are thermal insulation, air tightness, condensation resistance, floor impact sound insulation and sound insulation of walls. The purpose of this paper is to investigate the environmental performance of Mock-up model for building the prefabricated modular housings. This study set up the criteria for living performance and proposed the design of modular housing for small households. Mock-up model was built for testing the environmental performance as residential building. The major results are as follows. The thermal insulation performance of external wall used in the Mock-up model was evaluated as excellent one. The air tightness performance of one modular unit type was 4.7-7.0 ACH50 and that of two modular unit was 5.2-6.0 ACH50. The air tightness showed to be similar to the performance of apartment houses. The condensation resistance was evaluated by temperature difference ratio(TDR) and the TDR of corner walls was less than 0.2 of design criteria. The sound performance for light-weight impact sound source was 1 grade and The insulation performance for heavy-weight impact sound source was evaluated to be 3 grade.

Energy efficiency is high on the political agenda. There are many countries that have set goals to be less energy-intensive, to consume less energy and to decrease their carbon dioxide emissions. In the final energy consumption of Korea, the building sector accounts for 17.8% of a total energy consumption in 2013. The purpose of this study was to computed the energy intensity of residential building and commercial building using national statistics for building energy policy. Energy intensities are composed of the final energy consumption as numerator and activity data as denominator. Activity data in this study were population, GDP, value added of service sector, number of household & house, number of building mass and floor area. These intensity can be used as a time-series trend analysis and energy efficiency criteria. Energy intensity per floor area in residential building was 13.28×10<SUP>-3</SUP>toe/㎡(154.4Kwh/㎡) in 2013 and was reduced by 43.2% for 1996. Energy intensity per floor area in commercial building was 11.28×10<SUP>-3</SUP>toe/㎡(131.1Kwh/㎡) in 2013 and was reduced by 27% for 1996. The graphs and charts show that the time-series trend of these energy intensity has been consistently low.

International cooperation to reduce greenhouse gas emissions is expected to provide a big crisis and a great opportunity at the same time for our industry that heavily consumes energy. To cope actively with the international environmental regulation, such as the Framework Convention on Climate Change, quantitative measurement of the volume of greenhouse gases emitted by various industries and quantitative prediction of the greenhouse gas emissions of the future are becoming more important than anything else at the national level. This study aims to propose the calculation process of carbon dioxide(CO₂) emission for building in life cycle. This paper describes and compares 9 different tool for environmental load estimation with LCA. This study proposed the calculation process for quantitatively predicting and assessing CO₂ emissions during the life cycle of buildings based on the life cycle assessment(LCA). The life cycle steps of buildings were divided into the design/supervision, new construction, repair, renovation, use of operating energy in buildings, maintenance, and reconstruction stage in the life cycle inventory analysis and the method of assessing the environmental load in each stage was proposed.

The Korean government plans to introduce the building energy performance standard which regulates the annual energy consumption of buildings. This paper aimed to set up the reference building from database based on the building design trends for non-residential buildings. We surveyed the design data of 435 non-residential buildings which were granted building permission from 2007 to 2011. And we conducted estimation on the heating & cooling load and the energy consumption of the reference building using ECO2 program. From results, the reference building of non-residential buildings was office building which had a total 7 floors and 20,838 ㎡ gross floor area. And it suggests the design reference data of building envelope, HAVC, heat source equipment and lighting system for the reference building. The total annual energy use of the reference building was 151.9 kWh/㎡yr.

Assuring actual data for GHGs in the construction sector is needed to establish and perform reducing plan of GHGs for effective corresponding the Climate Change Agreement by a national point of view. CO2 Emission analysis during the construction stage of Apartment is assessed on the basis of major construction materials for a result of GHGs emission analysis. The assessment of the GHGs emission was executed with 25P, 34P, 43P and 57P apartment family unit as the destination. The result show that the average of GHGs emitting amount of new building step of an apartment is about 1.45 T-CO2. As a result of GHGs emitting amount of new building step of an apartment, GHGs emission per a house-hold is assessed about 0.438 T-CO2/㎡, and Green-house Gas emitting amount of an apartment construction could be assumed about 9,650,016 T-CO2 if 300 thousand of house-holds are constructed for a year.
