This study proposes design factors for Korean style ecological apartment for application in Cheongju. Library and internal surveys were performed to summarize the concept of locality in housing and to determine the present condition of apartment estates which were introduced with design factors according to locality, traditionalism, or ecology, fold surveys were carried out at 10 apartment estates to investigate the present condition of management and residents's un. The interviewees were concierges and representative residents. The following design factors for Korean style ecological apartment to be applied in Cheongju were proposed; layout and building shape according to climate as natural environment, landscape factors according to cultural assets as human environment, adolescent spaces according to population as social environment, road plan according to 'Cheongju Garosu-Gil' civil environment.

The purpose of this study is to investigate the Chinese investment environment and analyze the actual investment condition of Korean enterprises in China and examine the points at issue. In general, the investment environment in China shows satisfactory progress. China has a multiple and regional extension policy in investment. And the environment for investment changes to insufficiency of company profit, extension of service market, maintenance of legislative system, and insufficiency of preference about foreign company. There are situations of inclining to manufacturing, inclining of region, preference of independence investment, small-sized investment by small and medium enterprises, difficulty of financial assistance, excess of logistic cost, delay of logistic term, difficulty of settlement of legal dispute and difficulty of taking a relative information in investment of Korean enterprise in China. The results of the study indicate mostly that the investment of Korean enterprise into China needs turnover of service trade-tertiary industry, portfolio of investment territory, cooperation with Chinese enterprise through joint venture investment and a large-scale investment for extension of Chinese domestic market.

Departmentalized Classroom System is new school operating system to apply social needs. Recent social needs are characterized as learning environment and self-learning system. The purpose of this study is to provide basic data for equal learning environment condition in middle school applying departmentalized classroom system. This study has progressed through analyzing on 11 remodelling case of middle school in Gangwon-Do. The method of this study is visiting middle schools that operate the system, grasping the condition for environment composition, and investigating and analyzing practical use of the environment. The results of this study are summarized as follows: 1) The space compositions for departmentalized classroom system are generally desirable, but some schools take irrational space composition, especially on home base-teacher laboratory, classroom-teacher laboratory. 2) The space area distributions are different in every school. This result is based on not taking standard criterion on space area distribution.

According to the increasing concern about health and environment, students need to study in comfort and clean environment facilities. We did field survey on 40 primary schools to analyze the present condition of design and construction for the part of indoor environmental performance in the certificated green school building. We hope that this paper will offer the important data about the indoor environment standards and performances in primary school facilities.

We research hardware and software for measurement of most suitable condition of the plant growth. that is put of the future oriented that plant growing system. The environment cannot offer the most suitable condition of the plant growth. so we are approached most suitable condition of the plant growth by adjustment of artificial condition of the plant growth but in theses experiment includes some fault that is subjectivity of observation. therefor we develop vision equipment and software for objective observation measurement.

The fish community within the lake and 5 tributaries of Lake Chungju in spring and autumn, 2009 was surveyed. In this study, the total 128,506 individuals were collected belonging to 11 families 29 genera 34 species. The most dominant species was Squalidus japonicus coreanus that account for 91.6% of population and 49% of biomass of fish community. In the point of population, dominant species were small-sized species, which became the prey of big-sized predatory species. In the point of biomass, dominant species were predatory species which were large-sized. The most dominant species in lacustrine area was S. japonicus coreanus which accounted for 92.2% of total population and 49.1% of total biomass. The most dominant species of tributary streams was Tridentiger brevispinis which accounted for 66.4% of total population and 55.1% of total biomass. The site of C3 in lacustrine area and Dongdal-cheon in tributary streams collected the most number of species. Through ecological health evaluation of five tributary streams using 8 metric index of biological integrity (IBI) model, two streams (Dongdal-cheon, Kwang-cheon were evaluated as, "B", "good" condition, and Jangsung-cheon obtained grade C indicating "Fair" condition, Jecheon-cheon obtained grade D indicating "Poor" condition based on IBI model. Lepomis macrochirus which was designated as a domestic ecosystem-disturbing alien species with wide food niche have shown tendency to increase the number of individuals since 1991 indicating the adverse effect on not only fish community but also aquatic ecosystem food web of Lake Chungju.

This study aimed to determine the effects of relative humidity and fiber properties on the moisture permeability of multilayer systems by measuring water vapor transmission in the overlapping condition of various fabrics. The results confirmed that the property of the fabric in contact with the humid environment affects the moisture permeability. If the layer facing the humid environment is hydrophobic and the layer facing the dry environment is superhydrophobic, water vapor transmission increases by up to 17.8% compared to the opposite conditions. Comparing the correction values of the water vapor transmission reflecting the thickness of the specimen under the multilayer condition showed that permeability was higher when the hydrophilic or hydrophobic layer was facing the humid environment. The opposite was true from the "push-pull" effect of absorption mechanism. In the case of moisture permeability, the more hydrophilic the surface facing the humid environment, the more permeable that water vapor diffuses and passes through. It was concluded that the "pull-push" effect, in which water vapor diffuses widely through the hydrophilic facing a humid environment and then passes through the hydrophobic layer, contributes to the improvement of permeability. Permeability differed according to the multilayer overlapping condition. When the relative humidity was high, the "pull-push" effect was insignificant. This is caused by water droplets absorption after the partial migration of water due to condensation. These results suggest that the overlapping conditions and properties of fabrics should vary depending on heavy sweating or not.
