N-type ZnO nanorods were grown on p-type porous silicon using a chemical bath deposition (CBD) method (p-n diode). The structure and geometry of the device were examined by field-emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) while the optoelectronic properties were investigated by UV/Vis absorption spectrometry as well as photoluminescence and electroluminescence measurements. The field emission (FE) properties of the device were also measured and its turn-on field and current at 6 $V/{\mu}m$ were determined. In principle, the growth of ZnO nanorods on porous siicon for optoelectronic applications is possible.

자연어 정보처리 분야의 거듭된 발전은 다양한 언어처리 도구들의 출현을 가져왔다. 그러나 객관적인 성능 평가 기준의 부재로 인해, 개발된 도구들은 임의의 기준에 따라 평가될 수 밖에 없었다. 그 결과 성능 평가 결과는 평가자와 평가자가 제안한 기준에 따라 다를 수 밖에 없었고 따라서 평가 결과 자체 역시 설득력을 갖을 수가 없었다. 이와 같은 문제에 대한 해결책을 찾고자 하는 노력의 일환으로, 본 연구에서는 한국어처리 도구들 중 특히 구문분석기의 체계적이고도 객관적인 성능 평가를 목적으로 제작된 문장들과 관련 주석 정보들로 구성된 SERI Test Suites '97을 소개한다.

We assumed that natural history museums have rooms for functioning as institutions for the environmental education, especially in aspects of multi-disciplinary, informal education. So we set goals of this research as finding 1) how much environmental education contents are reflected in exhibits of natural history museums, and 2) what those characteristics in aspects of dimension, range, and topic are. First, we developed a framework for analyzing of environmental education contents. Second, we applied the framework to seven major natural history museums. As the result, environmental education contents are reflected by 69.1% totally. Especially, the 'knowledge' dimension covered mostly, and among them the range of 'elements of Ecosystem' occupied more than other ranges. With inferring our results, we suggested that characteristics of natural history museums in environmental education are followed; spatial-temporal expansion of bio-diversity concept, visualizing impacts of human activity against nature.

Two novel calcium-binding proteins, named CAB-I and CAB-II, have been isolated from Streptomyces coelicolor. Purification of the calcium-binding proteins involved heat treatment, fractionation with ammonium sulfate, acid treatment, anion exchange and hydrophobic interaction column chromatography, FPLC gel filtration, and preparative isoelectric focusing. A chelex competitive assay and 45Ca autoradiography verified the calcium-binding ability of the proteins. The major band CAB-II has an apparent molecular weight of 26,000 determined by SDS-polyacrylamide gel electrophoresis and 340,000 determined by gel filtration. The isoelectric point of this molecule showed the acidic nature of the molecule. N-terminal amino acid sequence analysis shows homology to rat Ca2+/calmodulin-dependent protein kinase-II (CAB-II) and yeast phosphoprotein phosphatase (CAB-I).

With the development of synthetic dyes, excellent dyeing properties and massive production became possible. On the other hand, natural dyeing technology has gradually disappeared. However, the international environmental and human safety requirements of the apparel and textile industry are increasing, and there is a growing interest in safer and more environmentally friendly products. Accordingly, the public's interest in natural dyeing is increasing. To meet these demands, it is first necessary to clarify the stages of production and distribution of natural dyes. It is necessary to evaluate whether the product is a natural dye product and study the suitability of the natural dye product through qualitative and quantitative assessment of the indicator components of the natural dye. Typical of three natural dyes did qualitative and quantitative analysis by HPLC-DAD and HPLC-MS. Products dyed using natural dye three products were analyzed, and the presence or absence of detection of each indicator components was confirmed to confirm whether the product was dyed using natural dyes.

This study aims to find the characteristics of damage and states of natural disasters at Gimhae, Gyeongsangnam-do from 1985 to 2004. Using the data of Statistical yearbook of calamities issued by the National Emergency Management Agency and Annual Climatological Report issued by the Korea Meteorological Administration. we have analyzed the cause, elements, and vulnerable regions for natural disasters. Major causes of natural disaster at Gimhae are four, such as a heavy rain, heavy rain typhoon, typhoon, storm snow, and storm. The cause of disaster recorded the most amount of damage is typhoon. The areas of Hallim-myeon, Sangdong-myeon, and Saengnim-myeon are classified the vulnerable region for the natural disasters in Gimhae. Therefore, it seems necessary to build natural disaster mitigation plan each cause of disaster to control water resources and to reduce damage for these areas.
