This study was conducted to provide an improving direction of K-EIP(Korean Eco-Industrial Park) construction project by company's voluntary participation. For this purpose, we investigated and analyzed the status of domestic eco-industrial park projects from various literatures, foreign EIP cases and FGI(Focus Group Interview). The key issues to construct a voluntary K-EIP are the lack of experts, the difficulties of commercialization financing, and so on. In this study, therefore, the programs to resolve these problems in K-EIP construction project were suggested at the level of government and corporation.

본 연구는 춘란 야생 변이종의 육종을 위한 기초 자료 를 얻고자 실시하였으며, 야생종의 개화시기를 꽃봉오리, 반개화, 개화, 개화 후 10일, 개화 후 20일의 5단계로 나 누어 자가 수분시킨 후 삭과의 형태적 특성과 발아율을 조사한 결과이다. 착과율은 개화 후 20일에 교배한 것에 서 100%로 가장 높았고, 삭과의 무게는 반개화 때 교배 한 것이 가장 무거웠다. 5단계로 나누어 발아율을 조사한 결과 반개화에서 가장 높게 나타났으며, 교배 후 채종 일수를 150일, 165일, 180일의 3단계로 달리하여 발아율 을 조사한 결과에서는 교배 후 채종일수를 150일에 파종 한 종자에서 5%로 가장 높게 나타났다. NaOCl 처리를 통한 발아율을 조사한 결과에서는 2%로 처리한 것에서 53.3%의 발아율을 보여 가장 좋은 결과를 나타내었다.

This research was conducted to estimate the characteristics of carbon dioxide decomposition using an inorganic sludge. The inorganic sludge was composed of high amount (66.8%) of Fe2O3. Hydrogen could be reduced with 0.247, 0.433, 0.644, and 0.749 at 350, 400, 450, and 500℃, respectively. The carbon dioxide decomposition rates at 250, 300, 350, 400, 450, and 500℃ were 32, 52, 35, 62, 75, and 84%, respectively. High temperature led to high reduction of hydrogen and better decomposition of carbon dioxide. The specific surface area of the sludge after hydrogen reduction was higher than that after carbon dioxide decomposition. The specific surface area of the sludge was more decreased with increasing of temperature.

This research was performed to evaluate heavy metal leaching characteristics of the sludge from paper mill process with sintering temperature. Heavy metal leaching of the sludge was characterized with Korean Leaching Test and Toxicity Characteristic Leaching Procedure. The test sludge was composed of 70.72% of moisture, 9.5% of volatile solids and 9.76% of fixed solids. As a result of XRF analysis, Fe was the highest inorganic element in approximately 83%, which implies the recycling possibility of the sludge in reuse of Fenton chemicals and artificial lightweight aggregate. Leaching of heavy metals from sintered sludge was lower than the dry ones. However, there was no significant difference in leaching characteristics between the sludges sintered at 350℃ and 650℃. Zn and Fe were leached more greatly in TCLP and KLT methods respectively.

우리나라 자연 상태의 노지재배에서 종자번식이 되 지 않는 크로코스미아의 기내증식을 위하여 2,4-D, NAA, kinetin, BA 처리가 캘러스 및 소자구 형성 등 에 미치는 영향을 조사하였다. 어린자방 배양에서 캘러 스 형성율은 BA와 2,4-D 혼합 처리에서 1~28%로 나타났으며 기내 뿌리 발생은 2,4-D, NAA 단독처리 에서 양호하였다. 소화를 이용한 배양에서는 kinetin +2,4-D, kinetin+NAA 조합에서 뿌리만 형성되기도 하 였다. rhizome 배양에서 줄기 형성에는 kinetin 단독 처리, kinetin+2,4-D 혼합처리가 양호하였으며 캘러스 형성에는 2,4-D 단독처리, 2,4-D+BA, 2,4-D+kinetin 혼합처리에서 25~92.8%의 형성율을 나타냈으며 corm 형성에서는 kinetin 처리와 kinetin + 2,4-D 0.1 mg·L-1 처리구에서 30~70%의 높은 형성율을 보였다.

본 연구는 울릉도 야생종과 도입된 원예종 40품종을 포장에 재배하여 화색 및 생육특성을 조사한 결과이 다. 꽃의 만개기인 7~8월 조사한 결과 화경장은 52~ 165cm 범위에서 분포하였고 엽수는 5~12개 엽장은 16~127cm의 범위로 나타났다. 크로코스미아는 소화경 이 경당 3~6개로 발달되어 있으며 한 개의 소화경에 부착된 소화수는 8~110개로 품종간 차이가 컸었다. 크 로코스미아의 화색은 적색, 주황색, 황색으로 구분되었 으며 화형은 dish형과 bell형으로 구분되었으며 dish형 품종이 많았다.

The present paper deals with gaseous carbon dioxide separation by a commercial adsorbent: X-type zeolite. Experimental work was carried out at an ambient condition focusing on how well meeting to the national guideline. A few types of reactor and material were examined, and practical capability was found in a granular bed type reactor with the flow of 2.5 CMM. An optimum design of reactor and adsorbent could provide the required concentration, less than 2500 ppm, for the continuous operation up to 10 hours. More work including automatic regeneration is now underworking.

Many researchers have been focused on polymer electrolyte membrane (PEM) to improve performance of a fuel cell. Sulfonpolyimide with hydrocarbon was synthesized from ODA (4,4-diaminodiphenyl ether), ODADS (4,4-diaminodiphenyl ether-2,2-disulfonic acid), NTDA (1,4,5,8-naphthalenetetracarboxylicdianhydride) and CSA (chlorosulfonic acid). In order to estimate the feasibility as a fuel cell, the performance of sulfonpolyimide was analyzed through a swelling degree, IEC (ion exchange capacity), ion conductivity and TEM (transmission electron microscope). As the results of this performance test, swelling degree, IEC and ion conductivity were 37%, 0.06 meq/g and 0.08 S/cm respectively, when the CSA concentration was 0.4 M. It was thought that sulfonpolyimide could be used as a fuel cell through improvement of electrolyte membrane.
