Relationship between growth rate and wood quality was investigated by physical and mechanical properties with Alnus glutinosa L.(24 years old) from 4 different origin of seed (Bulgary, Italy, United Kindom, Yugoslavia). Range of tensile strength were 11.16~12.90 kgf/cm2 and range of impact strength were 0.21~0.25 kgf·m/cm2. There were significant difference in tensile strength among different seed origin, but no significant difference in impact strength. Mean hardness were 4.34~5.00 kgf/mm2 �ﾠrange for cross direction, 1.36~1.48 kgf/mm2 for tangential direction, and 1.04~1.21 kgf/mm2 for radial direction. There were significant difference in impact strength among different seed origin for cross direction but no significant difference for radial- or tangential direction. There was no relationship between growth rate and mechanical properties (tensile strength, impact strength, or hardness).

박정훈,강대옥,박재국 한국특수아동학회 2003 특수아동교육연구 Vol.5 No.1

본 연구는 통학교육에서 장애유아의 적용기술에 대한 교사의 인식을 조사하기 위한 것으로 통합교육 프로그램을 준비하고, 실제적인 교육을 수행하는데 필요한 기초자료를 제공하고자 하였다. 부산시 유아교육기관의 일반교사 97명과 특수교사 60명을 대상으로 통합교육에 필요한 적용기술에 대한 인식을 설문지를 이용하여 조사한 결과 다음과 같은 주된 결론을 얻었다. 첫째, 통합교육에서 요구되는 적응기술에 대한 인식에서는 일반교사와 특수교사 사이에 차이가 없었으나, 하위 영역에서 특수교사들이 일반교사보다 적응기술의 중요성을 높게 평가하고 있다. 둘째, 통합교육에서 요구되는 적응기술의 하위영역에서 특수교사들은 집단활동 참여기술을 가장 중요하게 인식하고 있으나, 일반교사들은 독립생활기술을 가장 중요하게 인식하고 있다. 셋째, 장애유아 적응기술에 대한 교사변인에 따른 인식차이에서 통합경험이 없는 교사들이 적응기술을 중요하게 인식하고 있으며, 특수교육관련 연구경험이 없는 교사가 연수경험이 있는 교사보다 적응기술을 더 중요하게 인식하고 있다. 넷째, 성공적인 통합교육을 위한 교사의 의견에서는 교사의 긍정적 인식 및 태도를 가장 중요한 요인으로 인식하고 있으며, 학부모의 긍정적인 인식과 일반유아의 이해도 주요하다고 인식하고 있다. n This study aimed to determine teachers recognition of the adaptation skills of handicapped children for mainstream education and to provide basic materials for the successful execution of the programs to be prepared for mainstream education and actual mainstream education. This study considered 97 preschool teachers and 60 special teachers who were selected using random sampling, in Busan Metropolitan City. Questionnaires were distributed and collected, with responses reviewed and analyzed using SPSS Win 10.0. Results show no significant difference in the recognition of general adaptation skills of handicapped children required in mainstream education between special teachers and preschool teachers. In contrast, there is difference between the two groups in the sub-spheres of adaptation skills, in which spheres the importance of adaptation skills was more highly regarded by special teachers in the actual kindergarten education than ordinary kindergarten teachers thought. On the other hand, special teachers valued skills of participating in group activities the most in the sub-spheres of adaptation skills required in mainstream education while preschool teachers prioritized independent skills. To narrow such difference in recognition, correct understanding of and active exchange of information in mainstream education should be developed. In addition, teachers without experience in mainstream education were found to require a higher level of adaptation skills from handicapped children compared to teachers with experience in mainstream education. Likewise, teachers without educational training valued adaptation skills more compared to teachers with educational training. Both special teachers and preschool teachers expected a higher level of adaptation skills from handicapped children compared to mainstream education teachers. This suggests that special teachers or teachers without experience in mainstream education demanded a higher level of adaptation skills than actually necessary in mainstream education. The recognition of teachers also varied depending on the educational institution they belong. Finally, teachers considered the positive recognition and attitude of teachers, positive recognition of students parents, and understanding of children as mojor contributory factors to successful mainstream education.

Kano 모형에 기반한 소비자 요구사항 분류 : 퍼지 접근방법

임정훈,민대기,김광재 한국품질경영학회 2003 품질경영학회지 Vol.31 No.3

Kano model distinguishes three types of customer requirements, namely, one-dimensional quality, must-be quality, and attractive quality. There are a few methods for classifying a given customer requirement into one of the Kano's quality elements. However, the existing methods have a common limitation in that they are based on Kano evaluation table. Kano evaluation table is not always effective for the classification task, and suffers from a significant information loss. This paper proposes an alternative to Kano's evaluation table and a new classification scheme based on fuzzy set concept. The proposed method is illustrated using a case study on the ADSL service.

특수교육 분야에서는 이러닝을 통하여 장애학생 교육 서비스의 양적·질적 발전을 위한 다각적인 노력을 모색하고 있다. 그러나 특수교육 현장의 실제 활용 실태와 이와 관련된 구체적인 요구에 대한 기초연구가 부족하여 효과적인 이러닝 실행을 위한 지원 방향을 수립하지 못하고 있다. 따라서 본 연구는 특수학급 교사들을 대상으로 설문조사를 실시하여 특수학급의 이러닝 관련 환경과 활용 실태를 탐색하였고, 특수학급구성원들이 가지고 있는 이러닝 실행과 관련된 요구를 밝혔으며, 이를 바탕으로 특수학급에서 이러닝을 효과적으로 운영하고 실행하기 위한 시사점을 제시하였다. E-learning is learning that utilizes contents crafted based on multimedia and hyper media via diverse information technologies. It enables teaching and learning to allow disabled students to utilize contents crafted with diverse latest techniques, thereby expanding the forum of learning. Thus, the special education area is making diverse efforts to achieve quantitative and qualitative development of educational services for disabled students through e-learning. However, since basic research is lacking with regard to the actual utilization status of e-learning and corresponding needs in special education, an appropriate support direction for performing e-learning cannot be determined. Against such a backdrop, this research surveyed the e-learning status and needs in special classes. Likewise, it surveyed the environment and utilization status of computers, software, and assistive technology that special classes in 'B' and 'D' city owned for e-learning. It also surveyed hardware and software requirements for effectively performing e-learning in special classes.

Purpose: To show various MR spectroscopy and correlated pathologic images of retinoblastoma in nude mouse with a new human retinoblastom cell line (SNUOT-Rbl) which innoculated into intravitreous cavity. Materials and Methods: The established cell line was innoculated into mtravitreous cavity of 14 eyeballs of 7 mice and a transplanted retinoblastoma was examed for 1 month. Tl-weighted image (T1WI), T2-weihgted image (T2WI), and MR spectroscopy were obtained with 1.5 Tesla MRI (Magnetom Vision, Siemens, Erlangen, Germany) and 4.7 Tesla MRI (Bruker, Medizintechnik GmbH, Karlsruhe-Ettlingen, Germany). After scanning, eyeballs were extracted and hematoxylin & eosin stained specimens were examined with the microscope. We compared MR spectroscopy with pathologic findings and evaluated characters of tumors. Results: Innoculated cells into eyeball of mice grew retinoblastoma (8/14, 57%). Eyeball with retinoblastoma protruded externally and showed focal hemorrhage. Tumors showed low (n=3), iso (n=4), high (n=1) signal intensity on TIWI, low (n=5), iso (n=1), high (n=2) signal intensity on T2WI, and well enhancement (n=8) with contrast, Involvement of optic nerve was suspected by MRI and confirmed by pathology (n=1). Conclusion: We could demonstrate MR spectroscopy of transplanted retinoblastoma by new tumor cell line in vivo. This imaging technique facilitate molecular imaging investigation of retinoblastoma.
