As the environmental pollution is intensified, the interest in the conservation and quality of global environment is also increasing. Interior design affects on environmental conservation as well as the quality of outdoor and indoor environment through all phases of interior design. Therefore, interior designers should do environment-friendly design. The purpose of this study was to examine the consciousness and application degree of environment-friendly interior design in actual project by interior designers. The study was conducted by a questionnaire survey. The subjects were 215 interior designers working in Seoul area. The major findings of this study were as follows: 1) The 33 representative elements of environment-friendly interior design were selected and categorized into 5 fields: resources and materials, energy savings, ecological environments, indoor environments, and space effectiveness. These would be useful to carry out environment-friendly interior design projects and related researches. 2) Many interior designers didn't understand what the environment-friendly interior design is correctly, even though they were interested in it. Therefore, the educational program of environment-friendly interior design should be developed. 3) Even though interior designers thought most elements of environment-friendly interior design very important, they didn't apply them well to actual projects. This implies that alternatives for activating them are needed.

Build-Transfer-Lease (BTL) was introduced to the domestic construction market in 2005. Now, seven years later, the BTL model is most active for educational facilities. In 2011, 93 educational facility projects entered the maintenance stage. Considering the characteristics of today's BTL projects for educational facilities, the main issues are the initial performance and maintenance of educational facilities and the service-providing status for the 20-year operational management period, in relation to providing safety and convenience to students, the facility users. Seeking a solution, local education offices and departments in charge of BTL under the Ministry of Education, Science, and Technology have been exploring various methods of evaluating operational maintenance performance from various perspectives. For educational facility BTL projects, however, the appropriateness of initial operation performance evaluation, rather than considering the 20-year operational management period, is controversial in regards to sustainability. On this account, performance evaluation items in four areas-operational maintenance evaluation, facility performance status evaluation, maintenance subject evaluation, and sustainable change response evaluation-should be extracted. An indicator of facility performance evaluation is presented in this study through an AHP survey targeting experts, as part of establishing an operation performance evaluation system for educational facility BTL projects.

To start with, finding a sustainable method to produce sweet water and electricity by using renewable energies is one of the most important issues at this time. So, experimental and theoretical analysis of the performance of a closed solar powered still, which is jointed to photovoltaic cells and vacuum pump and equipped by nano plate, as the principle stage of zero discharge desalination process is investigated in this project. Major goal of this work is to reuse the concentrated brine of the Mobin petrochemical complex in order to produce potable, sweet water from effluent saline wastewater and generating electricity in the same time by using solar energy instead of discharging them to the environment. It is observed the increase in brackish water temperature increases the average daily production of solar desalination still considerably. Therefore, the nano plate and vacuum pump are added to augment the evaporation rate. The insolation rate, evaporation rate, the average brackish temperature, ambient temperature, density are investigated during a year 2013. In addition to obtain the capacity of solar powered still, the highest and lowest amount of water and electricity generation are reported during a twelvemonth (2013). Results indicate the average daily production is increased 16%, which represents 7.78 kW.h energy saving comparing with traditional solar still.

Green landscape plan to the riverfront area of the Han River The Han River, one of the symbolic elements in metropolitan Seoul, structures an axis of waterscape as the openspace crossing east to west of the city of Seoul. As riverside urban motorway(88 Olympic motorway) and riverside public park were constructed by the Han River Comprehensive Development Project in 1986, the necessity of general plan for the in-stallation of envirommental facility belt to conserve living enviroument is being required with relation to, dense residential areas closed to the river Therefore, the goal of the study is to provide better riverview and to increase environmental purifi-cation ability as a large scale waterscape axis by the preparation of landscape plan to the riverfront area of Han River, In order to achieve the goal, the study deals with sectional speciality, the introduction of landscape assessment techniques and ecological approach to given environment. As unity is kept through whole waterfront area, the area is divided into 9 zoning sections to study development methods for each section, and themes for speciality are given to each section, and the. sort of plants which can be symboliged to the area is selected. Also, the planting methods for harmony with the type of road structure and riverscape is offered. Though the study may give significane to the image and the function of riverside road, in con-clusion, the characteristic ecological approach to the river is so limited that has not been reflected enough on the plan. It is expected that the study should be continued, and long-term riverfront openspace plan, environmentally sustainable, should be arepared.

The introduction of Strategic Environmental Assessment (SEA) has strengthened and extended the value of Environmental Impact Assessment (EIA) as a fundamental tool for sustainable development. In particular, SEA helps to overcome the limitation of project EIA as a stand alone approach that is applied relatively late in the decision making cycle. SEA is applied to proposals of policy, plan, and/or programme when major alternatives are open. In Korea, similar to SEA, the Prior Environmental Review System (PERS) was introduced to overcome the limitations of the EIA, by checking the environmental impacts on major policy and administrative actions in the early stage of decision making process. SEA appears in various national, regional and international laws. SEA is addressed specifically in the UNECE SEA protocol to the Espoo Convention on Environmental Impact Assessment in a transboundary context, as well as the European Commission SEA Directive (2001/42/EC). SEA is a valuable tool for integrating sustainability decisions into country's policies, plans and programmes. This paper reviews the policy direction for implementation of the SEA and efficient Environmental Assessment (EA) through integration of the PERS and the EIA.
