이 연구의 목적은 '일상적 정보행태의 관점'에서 재미한인의 삶을 조망하되 거주지역과 민족정체성이라는 변수가 그들의 정보행태에 어떠한 영향을 미치는지를 심층적으로 들여다보는데 있다. 이를 위해 이 연구에서는 기존 연구에서와는 달리 학자들의 관심에서 상대적으로 소외되어 있던 미(美)대륙 중서부에 위치한 3개 주(洲)(켄터키, 인디애나, 오하이오)에 거주하는 한인들을 관찰의 대상으로 삼고 있다. 논의를 위해 필요한 자료는 기본적인 문헌조사에 더해 설문조사와 면담을 통해 수집하였다. 연구 결과, 거수지역과 민족정체성에 따라 재미한인의 정보행태는 다양하고 복합적인 양상을 띠고 있는 것으로 확인되었으며, 이를 근거로 재미한인과 같은 소수민족 집단을 위한 정보복지정책은 정보행태의 다양성과 복합성을 반드시 고려하여 수립되어야함을 권고하고 있다.

Building a competency of pre-service school teachers is one of the critical factors to decide right direction of k-12 computer & information education. In this context, we can realize of the importance of computer & information curriculum for pre-service school teachers. The purpose of this study is to explore the case of the CEL(Computer Educator License) program in Indiana University and to find the developmental direction of technology education for pre-service school teachers. To achieve the purpose of study, the methods and procedures involved the following steps: The literature reviews of technology education were performed. The analysis framework based on case study method was designed for collecting data. Data were composed of related documents, web resources, and interview resources. And collected data were analyzed. The finding and recommendation of this study were the importance of following factors: (a) technology integration in the curriculum for pre-service school teachers, (b) differentiated management with skill-based technology education, (c) leadership for using and diffusing technology in the school, and (d) connected curriculum with the national standard indicator.

National Agricultural Pesticide Risk Analysis (NAPRA) WWW 시스템 (http://pasture.ecn.purdue.edu/${\sim}napra$)은 각기 다른 영농방법이 지표수질, 유사, 그리고 지하수질에 미치는 영향을 평가하기 위하여 개발되었다. 이 NAPRA WWW 시스템은 Total Maximum Daily Loads와 같은 수질 요건을 만족시킬 수 있는 최적영농 방법이 무엇인지 찾는데, 그리고 수질측면에서 취약한 지역을 찾아내는데 매우 효율적인 시스템이다. 이 NAPRA WWW 시스템을 이용하여 미국 인디애나주의 수계에 대해서, NAPRA 모의 Nitrogen과 Atrazine 결과를 실측치와 비교하였다. 18개 수계에 대해서 NAPRA 예측 질소값과 실측 질소값을 비교한 결과 $R^2$ 값은 0.51이고, 6개 수계에 대해서 NAPRA 예측 Atrazine값과 실측값을 비교한 결과 $R^2$ 값은 0.87이었다. 이 연구에서 보여지는 바와 같이 NAPRA WWW 시스템은 수계내에서 질소와 Atrazine에 따른 오염지역을 찾아내는데 효율적으로 사용될 수 있는 시스템이다.

구리, 인디움, 셀레늄 이온을 포함한 혼합물을 전기화학적으로 환원하는 1회 반응으로 CIS 입자를 합성하였다. 합성된 입자를 폴리(옥틸티오펜/풀러렌으로 구성된 벌크이종접합에 블렌딩하거나 박막층으로 삽입하여 여러 가지 광기전셀을 제조하였다. CIS의 함량이 증가할수록 개방전압과 단락전류의 급격한 감소가 일어났다. 이러한 광기전성의 감소현상을 블렌드의 구조, 조성, 모폴로지를 분석 해석하였다.

This design proposal was accepted to a design competition for the improvement of Indi Youth Street, Mapo-Gu, which was held by the Seoul Metropolitan Government in June, 2000. The \`Hong-ik University District\` projected area consists of several streets, where the independent and youth culture unique to this area is blossoming-Indi music, underground arts, and historic meaning of the area as an estuary of Mapo. The site is also expected to attract many citizens and fereigners because of convenient accessibility of the new subway station to the Inchon International Airport and because of many attractions on the street- foods, music, art and people. Accordingly, the proposal set the main design concept of this project as \`the Street of Youth Culture\` considering its special and social status as well as the physical improvement of the street environment. With this concept in mind, the proposal designed the improvement of the physical conditions based on the motive of \`the Street of Youth Culture\`, having Indi/under art, Indi/ under music, Indi/under drama and Indi/multimedia animation. This design proposal of the Street of Youth Culture consist of three segments, which symbolize the millenium Youth Plaza, MultiMedia Animation Pocket and Arts Exhibition Pocket based on unity and balance. This plan has the ultimate aim of making the district one of the people\`s favorite streets in Seoul, which people love to visit again and find the vivacity of the new millennium youth culture.

The primary purpose of this study was to identify the diversity and embellishment of American Indian clothing and relationship between culture and clothing in American Indian Culture Areas. After the introduction of European material culture, change in American Indian clothing was conducted. The result of the Study as follows: 1. The most influential factors affecting the diversity of American Indian clothing were environmental factors. Climates and geographical features, Raw material were reflected in clothing style and clothing material in each culture Area. 2. Economic situation and life style were shown to be influential to clothing development. The best known instance of this was greatly elaborated clothing and personal adornment of the Plains who had higher stand of life and nomadic life style. 3. Religious concepts were important factors influencing American Indian clothing. Indian tribes had different ritual performance they used particular motifs in clothing. Clothing, such as "ghost shirt", Apache medicine shirt and Pueblo ceremonial clothing, served hidden pur- poses. 4. Techenology was another factor identified in this study as influencing American Indian clothing. Especially, weaving skills of Southwest played a great role in textile development. Pueblo "manta" and Navaho "bil" were famous for Indian costume. 5. European material culture allowed great change of traditional native Indian clothing. American Indian had new material, new styles, new concept of clothing. 6. American Indian, although Indian applicated European trade goods, was actually quite conservative in retaining traditional designs and modes of decoration. Asthetics and traction of American Indian were reflected in American Indian clothing.d in American Indian clothing.

Recently, polyester is widely used in textile fabrics due to its application potentials in various fields. It is known that askin fabric is prepared with mainly polyester and is enjoyed with various end uses such as marine clothing, underwear, shirts, swimming suits and so on. For this purpose, color fastness should be considered with great importance during its wet processing step. In this context, vat dyes were very much attracted due to the advantage of superior fastness property. Thus, we have used indigo dye towards askin fabric dyeings and investigated corresponding properties namely, dyeing temperature, concentration of dye, reducing agent amount and alkali amount. The results showed that higher color strengths of indigo dyeing on askin fabric were obtained at $110^{\circ}C$, 8% o.w.f, 3g/l, 5g/l, respectively. The color fastness to washing was considerable generally.

Indican (indoxyl-${\beta}$-D-glucoside) is a colorless natural compound and can be used as a precursor for the production of indigo. This production step only require an enzyme, ${\beta}$-glucosidase, that readily screened from microbial resource by using selective media supplemented with indican as a sole carbon source. Agrobacterium tumefaciens was well grown in this media and thus presumed to produce a related enzyme. The corresponding gene, encoding a protein with a calculated molecular mass of 51 kDa, was cloned and overexpressed as MBP fusion proteins. The purified enzyme was determined to be a dimer and showed the maximum activity for indican at pH 7.0 and $40^{\circ}C$. The kinetic parameters for indican, Km and Vmax, were determined to be 1.4 mM and 373.8 ${\mu}M/min/mg$, respectively. The conversion yield of indican into indigo using this enzyme was about 1.7-1.8 folds higher than that of previously isolated enzyme from Sinorhizobium meliloti. Additionally, this enzyme was able to hydrolyze various ${\beta}$-1,4 glycoside substrates.

벼 품종의 오존 저항성 판단을 위한 시험에서 오존의 처리농도는 0.3 ppm이 0.1 ppm보다 뚜렷한 결과를 보였고, 처리시간은 2∼4시간이 알맞은 것으로 나타났다. 묘대일수에 따른 저항성 정도는 파종후 3주까지는 생육이 진전될수록 높아지는 경향이었으나 3∼5주간에는 큰 차이가 없었다. 인디카와 통일형 품종들이 자포니카 품종보다 저항성이 높은 경향이었고, 자포니카 품종 중에서 장안벼외 7 품종은 높은 저항성을 나타내었다. 벼의 생육시기에 따른 피해엽율은 간척벼는 유묘기에서 밀양 2003외 4 품종은 최고 분열기에서 가장 높게 나타났고 임실율은 수잉기 처리에서 가장 낮았다.

본 논문은 단일 버스를 사용한 밀결합 다중프로세서 시스템에서 데이타 전송량을 극대화하기 위해 파이프라인 전송 기능을 가지는 버스 프로토콜를 제안한다. 이 버스는 어드레스와 데이타의 전송을 위해 독립적인 전송 통로와 블록 전송기능을 두고, 최애 264 Mbytes/sec 데이타의 전송 능력을 가진다. 이버스를 기반으로 각각의 프로세서 보드의 내부에 캐쉬를 포함한 다중프로세서 시스템을 모델링하고, 시뮬레이션를 통해 캐쉬의 메모리의 참조율 변화에 따른 버스의 성능 및 시스템의 성능을 평가한다. 본 버스를 이용할 경우 10개 까지의 프로세서 보드가 버스에 장착되어도 버스가 포화되지 않고, 4개 까지의 메모리의 인디리빙에 대하여 성능이 선형적으로 증가함을 알 수 있다.
