As a result of the rapid development in the information technology and the wide spread of the Internet, we are introduced to a new age of global electronic trade(e-Trade). Global e Trade indicates a new trade pattern that most of the procedures including marketing, negotiations, contracts, sourcing, distibution, payments are performed upon cyberspace using the Internet and World Wide Web(WWW). To strengthen their overseas promotion and international marketing ability, many small and medium sized companies in advanced countries are utilizing the Internet and WWW actively in their international trade procedures. However, according to the recent survey of the Korean International Traders Association(KITA), the utilization of global e-Trade in Korean small and medium-sized companies is very limited despite of the proven advantages of the global e-Trade. Among many global e-Trade related technologies, Trade portal site is one of the most easily accessible tools in exploring overseas market without much time and cost, even in small and medium-sized companies. This study is originated in the necessity of facilitating the use of trade portal sites more efficiently by Korean small and medium-sized companies to enhance their global competitiveness. An empirical survey based on e-mail questionnaire is conducted to find out the significant factors which affect user satisfaction of trade portal sites. First, according to the factor analysis, the major functions of the trade portal sites affecting user satisfaction of trade portal sites can be grouped by three categories such as degree of satisfaction in transactional function, in informational function, and in publicity and offer function. Next, using regression analysis, the significance of the factors is examined in those three functional contexts along with entire degree of user satisfaction. In summary, the most significant factors affecting the user satisfaction of trade portal sites are information characteristics, ease of use, and trade support function. However, it is found that appearance and technological characteristics are not significant factors. Accordingly, it can be concluded that to facilitate the use of trade portal sites by Korean small and medium-sized companies, trade portal sites have to try their best in reinforcing their information contents, user friendliness, and trade support function more than ever. * A thesis submitted to the committee of the Graduate School, Chungnam National University partial fulfillment of the requirement for the degree of Master of International Management in February 2004.

Composites based on brominated isobutylene-isoprene rubber (BIIR) and 5-mm short aramid fiber were prepared by varying the fiber content from 1 to 10 phr using 4, 4’ bismaleimido diphenyl methane (BMDM) and zinc oxide as the vulcanizing agent. Morphological analysis revealed that the fiber dispersion becomes inferior even at 5 phr loading due to fibrillation during mixing. As a result, the 10 phr fiber-filled composite showed a brittle failure under a tensile deformation. To solve this problem, maleic anhydride-grafted polybutadiene (MA-g-PB) resin was treated with the aramid fibers in the 1:1 ratio prior to mixing with the rubber matrix. Excellent fiber dispersion could be seen in both the visual image of the molded sheet and the scanning electron microscope image of the fractured surface. The stress–strain curve of the 10 phr fiber-filled composite after the resin treatment showed a tough deformation behavior with a breaking elongation >100% indicating an enhanced fiber-matrix adhesion. From the vulcanization studies of the fiber-filled BIIR before and after the MA-g-PB resin treatment, it has been identified that a co-crosslinking reaction between the MA-g-PB-treated fiber and the BIIR matrix with BMDM via Alder-ene and Diels-Alder reactions is responsible for the enhanced fiber–matrix adhesion. Composites based on ethylene-acrylic rubber and 1mm short aramid fibers (AF) were developed by varying the fiber content from 3 to 40phr. At 10phr short fiber loading, the tensile modulus (10% modulus) of the neat matrix was around 11 times increased. However, its breaking elongation was decreased from 408 to 58%. This drastic reduction in the breaking elongation even at a 10 phr fiber loading leads to a brittle failure with inferior toughness. The tensile-fractured surface of the fiber-filled composite showed an intact matrix with no plastic deformation during fiber pulled-out. To solve this problem, carbon black (CB) was used as a toughening agent. Surprisingly, the addition of 20 phr CB onto a 10phr AF-filled composite enhanced its 10% modulus in the longitudinal direction by 70% and also enhanced its breaking elongation from 58 to 351%. From the morphological analysis, it has been presumed that the addition of CB enhanced the friction between the fiber and the matrix at a very low strain and also facilitate the matrix for a plastic deformation at a higher strain. This enhanced friction between the fiber and the matrix is considered as the improved low strain modulus and the subsequent plastic deformation at a higher strain is responsible for the improved toughness.

한 학기 한 권 읽기 수업이 고등학생의 읽기 태도에 미치는 영향 연구

성윤재 고려대학교 교육대학원 2020 국내석사

21세기 정보화 사회에 필요한 인재를 양성하기 위해 학교 교육 현장에서는 독서 교육을 어느 때보다도 강조하고 있다. 독서 교육은 읽기 능력을 갖추고 스스로 독서하는 독자 양성을 목표로 하였으나 지나친 인지 기반의 전략적 읽기 지도로 인해 읽기 능력은 갖추었으나 읽기를 싫어하고 거부하는 비독자(aliterate reader)가 양성되었다. 인지적 영역과 정서적 영역의 균형적 발달을 위해 2015 개정 교육과정에서는 한 학기 한 권 읽기를 핵심 정책으로 내세웠다. 그러나 아직 한 학기 한 권 읽기가 도입된 초기 단계이기 때문에 수업의 효과성이 증명된 연구는 매우 부족한 상황이다. 따라서 본 연구는 고등학교 1학년 학생들을 대상으로 한 학기 한 권 읽기 수업을 실시하여 수업 후 학생들의 읽기 태도가 긍정적으로 변화했는지 확인하고 이를 통해 한 학기 한 권 읽기 수업의 효과성을 알아보고자 하였다. 이를 위해 세 가지 연구 문제를 설정하였다. 1. 한 학기 한 권 읽기 수업 이후 연구 대상들의 읽기 태도가 변화했는가? 2. 연구 대상의 특성에 따라 읽기 태도 변화에 차이를 보이는가? 1) 성별에 따라 읽기 태도 변화에 차이를 보이는가? 2) 국어 교과의 학업 수행 능력에 따라 읽기 태도 변화에 차이를 보이는가? 3) 독서량에 따라 읽기 태도 변화에 차이를 보이는가? 3. 한 학기 한 권 읽기 수업에 대한 학생들의 반응은 어떠한가? 연구 문제를 해결하기 위해 2018학년도 2학기에 14차시에 걸쳐 한 학기 한 권 읽기 수업을 실시하였고, 수업 전과 후에 설문조사를 실시하여 학생들의 읽기 태도를 확인하였다. 한 학기 한 권 읽기 수업에 대한 학생들의 반응을 파악하기 위해서는 심층 면담을 진행하였다. 설문조사와 심층 면담을 실시한 결과 한 학기 한 권 읽기 수업 후 학생들의 읽기 태도 점수가 긍정적으로 변화했으며 향상된 점수는 통계적으로도 유의함을 확인할 수 있었다. 또한 연구 대상의 성별, 국어 교과의 학업 수행 능력, 독서량과 같은 특성에 따라 읽기 태도 변화에 차이를 보이는지 확인한 결과 학생들의 읽기 태도 변화에 성별과 국어 교과의 학업 수행 능력의 특성은 유의한 상관을 보이지 않았다. 그러나 학생들의 읽기 태도 변화에 독서량의 특성은 유의한 상관을 보이는 것으로 나타났다. 전체 연구 대상의 98.8%가 한 학기 한 권 읽기 수업에 만족한다고 답변하였으나 타교과와의 협력을 통한 한 학기 한 권 읽기 수업 시간 확대, 다양한 도서 목록 추천, 학생들의 특성과 수업 상황을 고려한 수업 운영 방식 조정, 독서 일지 양식 개선 등의 문제를 보완할 것을 요구하였다.

성윤재 부산대학교 2012 국내석사

Purpose : To evaluate the usefulness of dynamic Magnetic Resonance Imaging(MRI) for the treatment of sequelae of septic hip by the morphology of cartilaginous femoral head and exact relationship with acetabulum after acute stage management. Materials and Methods : Dynamic MRI examination was performed on 8 children (16 series of dynamic MRI) having sequelae of septic hip. Based on Dynamic MRI findings (from five positions: neutral, abduction, abduction with internal rotation, abduction with internal rotation and flexion, adduction), we obtained plans of preoperative treatment or conservative treatment(Pavlik harness). The average follow up period were 9.3 years (from 3.0 to 13.5 years) after operative treatment or conservative treatment. Results : Based on Dynamic MRI findings, we determined varus or valgus osteotomy of proximal femur in 4 patients and conservative treatment (Pavlik harness) of avascular necrosis of the femoral head and femoral head deformity in 3 patient. Satisfactory outcome of acetabular containment and development were shown in 7 patients. Conclusion : Dynamic MRI gives detailed information about the presence of femoral head, shape of deformity, degrees of dislocation or subluxation and correlation between femoral head-acetabulum. Dynamic MRI is also helpful in establishing treatment plan when femoral head ossification center is not present, it can replace the conventional arthrography. It is helpful to determine the stability of hip joint when conservative treatment is planned. We could determine the surgical treatment of femoral varus and valgus osteotomy by the ideal hip position from Dynamic MRI based on the congruity of the femoral head and acetabulum.
