Lee, Yo-An(2010), “Analysis of Curriculum Components of Language Teacher Education:Enhancing Academic Knowledge or Developing Professional Skills?”, Language & Information Society 13, Two of the principal goals of language teacher education are to enhance teachers` academic knowledge and to develop their teaching practices. Yet, there is a paucity of empirical studies to verify how these goals are realized at actual curriculum of teacher education programs. The present study investigates curricula of language teacher education in order to identify how these dual goals are addressed across programs at the curriculum level. First, the analysis of required courses of 30 randomly selected programs shows that there are too small a number of language education courses to address relevant topics and issues with a sufficient depth. Furthermore, linguistics and education have figured most prominently in academic content across curricula, although linguistic courses outnumber education courses considerably. Second, a detailed case study of one teacher education program looks into the relationship between programmatic features behind its curriculum and the students` evaluation of them. It is found that, while the course works are designed to develop students` conceptual capacity for their independent decision-makings in their classrooms, students are more concerned with whether and to what degree given courses reflect their classroom realities. Implication for curriculum designers and further studies are discussed.
Maximum Ratio Transmission 기법의 MIMO 다중경로 페이딩 채널로의 확장
이경규,이원철,신요안 崇實大學校 生産技術硏究所 2001 論文集 Vol.31 No.-
To effectively improve capacity on fading channels in the third generation and beyond mobile communication systems that require high quality and capacity, spatial diversity schemes utilizing MIMO (Multi-Input Multi-Output) concepts have been identified as an efficient way of improving the capacity without expanding the bandwidth. Among various MIMO spatial diversity schemes, MRT (Maximum Ratio Transmission) which maximizes signal-to-noise ratio at the reception has been recently proposed. In this paper, we extend the conventional MRT scheme which is restricted to flat fading channels to MIMO multipath fading channels, and analyze the bit error rate performance.

This survey was made in order to study adaptable soil site for black locust. The relation of the soil characteristics to the growth of black locust in the area was analyzed. (1) Black locust has shown better growth on the site which has deeper effective soil depth, lower compactness and consistency, and more of available phosphate content. The ratio of growth of ground cover vegetation under black locust depended on the site quality. (2) It has shown the trend of better growth on the soil which has better C,E.C., and in the soil class siallitic sail than sandy soil. (3) Summarizing above result, the best suitable site for black locust is where effective soil depth is better than 40 cm, compactness & consistency is less than 2.5, available phosphate in the soil is more than 2.0prm, 20% of humus, C.E.C. of 20mm/100 and the soil class of siallitic soil.

We evaluated CT findings of the small cell carninoma, which presented as a solitary pulmonary nodule at the periphery of the lung parenchyma. Of pathologically-proven 45 patients with small cell carcinoma, 10 patients was included in this study, who had a solitary, peripheral lung nodule at distal portion of the subsegmental bronchus. We retrospectively reviewed clinical data and CT findings including size, location, margin, enhancement pattern, lymph node enlargement, metastasis. Peripheral small cell carcinomas were 22.2%(10/45). All masses had well-defined margin and lobulated margin was seen in 7 patients. Mean diameter was 3.8cm (2.5-7.0cm). Enhancement pattern were homogeneous in 3 cases and inhomogeneous in seven. Calcification or air-bronchogram was not present, and focal cavitation was seen in one case. In five, only lung mass was present, and lung mass with lymph node enlargement was seen in one. distant metastasis without lymph node enlargement was noted on two patients and another two patients showed lymph node enlargement and distant metastasis. Peripheral small cell carcinoma is not rare(22.2%). Most frequent CT finding is a well-defined, lobulated mass with inhomogeneous enhancement, these findings would be helpful in differentiating small cell carcinoma from other neuroendocrine tumors when differentiataion is difficult cytologically.

The puropse of this study was to investigate the recognition of body shape, the difference between self-evaluated obesity and obesity index of RBW, and attitude toward weitht control of middle students. The questionnaires were completed by 195 male and 189 female students of liveing in Yongwol county. The followings are the results of this research. 1. The average stature of the boys is 166.97 ±6.21cm, the girls is 158.13 ±5.83cm, and the average weight ofthe body is 57.97±12.39kg. the girls is 52.88±8.35kg. 2. In the present body structure ofthem,the underweight structure is 6.0%, the normal weight structure is 87.2%, and the oveweight sturcture is 6.7%. In the recognition of their own body structures,there are meaningful differences between boys and girls. 3. In the contentment degree of the present body structure of their own, the underweight sturcture is much more satisfied with it.(p〈0.001) It shows a meaningful difference between boys and girls. 25.6% boys are satisfied with their own body structures, and 7.4% girls are satisfied with it.(p〈0.001). 4. In the interest degree about the weight's control, 87.1% is interested in it, it is olwer in the underweight structure. 88.0% girls and 77.4% boys are interested in the weight's control. There is a meaningful difference between boys and girls, too(p〈0.001) Each of the weight groups has differences in a experienced or experiencing for the weight's control 5. The recognition degree of the present body structure showed the meaningful positive relation to the contentment degree of the present bldy structure and the weight's control.(p〈0.001)
