The IGRINS is a near infrared high resolution spectrograph jointly developed by the Korea Astronomy and Space Science Institute and the University of Texas at Austin. We present design and fabrication of the optomechanical mount for the five mirrors, i.e., an input fold mirror, a slit mirror, a dichroic, and two camera fold mirrors. Based on the structure analysis and the thermal analysis of finite element methods, the optomechanical mount scheme satisfies the mechanical and the thermal design requirements given by the optical tolerance analysis. The performance of the fabricated mirror mounts has been verified through three IGRINS commissioning runs.

As getting into the 21st century, we can say it is ecological danger if there is a particular concern. Facing onto this very ecological danger, lots of effort are being made in various way to make sustainable development. In this study, under the theologic thought and the ecological fundamental notions, we are willing to plan the way of making up an ecovillage by the spirituality community. We are searching the way how we solve these problems in future by setting up the ecological spirituality community in each group's assumption, according to research from the people belonged to the organisation of Korean national christians' spirituality community and announcement and discussion about the subject called 'Finding Lost Garden'

The objective of this study was to identify ecological environment elements that may be introduced in creating urban apartment complexes and to suggest possible options on how to introduce them. To this end, a questionnaire survey has been mailed to 120 residents-to-be of apartment complexes to suggest ecological environment elements and techniques preferred by residents-to-be and, accordingly, they have been applied to study areas. The detailed results of this study are as follows. (1) Introduction of diverse plant species instead of plantation using grasses only and considering the height and density of planting adequately appeared effective in enhancing ecological diversity as well as visual preference. (2) Creation of eco-ponds using rainwater was one of the most desirable options in urban apartment residential complexes. Also, eco-ponds can increase visual preference when they are arranged through adequate vegetation management. (3) The results showed that when creating habitats for such as insects using porous space, it is desirable to consider a visual aspect first and then to create habitats for various insects. When the results of this study are actually applied to a real study area, it will be able to increase ecological diversity in urban apartment complexes as well as raising visual preference. Accordingly, it should be introduced proactively in planning, designing, and creating real apartment complexes.

This design proposal was made for the school forest plan of Samdeok Primary School and which goals were to realize the programs of making the school forest and removing the school wall. The results of developing programs could enhance the existing conditions of the school from the primary educational state to the sustain-able and friendly nature state.The site is located at 361 Samdeok-3ga, Jung-gu, Daegu and which is about 15,150㎡ and divided into 2 parts of design site of 150m in length, 15m in width respectively. The client suggested some guidelines to develop spaces of environmentally and educationally-friendliness without reducing athletic area. The design concepts are divided into 4 thematic activities such as Open Education, Outdoor Music Activity, Ecological Educational Activity and Social Interrelated Activity. The master plan has two seperated areas which are the main gate area and the back side of the school. The basic plan of the main gate area is characterized by the school forest which has Pine Tree Forest, Rock Shelter, Forest with Pictures and Books, Wild Flower Bed, Gravel Road, Outdoor Music Theater, Forest with Poets and Music, Monumental Sculptures. The back side area has also many various design components such as Decorated Seating Wall with Tree Shades and Bird Nests, Street Mini Park, Small Pond, Shaded Trees and Hedges. This project was constructed from May to June, 2005 as the first year budget of the school. But the limited budget cut down and reduced many parts of the whole design and that is the main problem of this project. The school could solve this problem gaining many kinds of funds from the various sources such as Deagu Metropolitan Office of Education and The P.T.A etc.
