Background: The objective of this research is the computed axial tomography (CT) imaging grading of radiation induced pneumonitis (RP) and its correlation with clinical and radiotherapeutic parameters. Materials and Methods: The chest CT films of 20 patients with non-small cell lung cancer who have undergone threedimensional conformal radiation therapy were reviewed. The proposed CT grading of RP is supported on solely radiological diagnosis criteria and distinguishes five grades. The manifestation of RP was also correlated with any positive pre-existing chronic obstructive pulmonary disease (COPD) history, smoking history, the FEV1 value, and the dosimetric variable V20. Results: The CT grading of RP was as follows: 3 patients (15%) presented with ground glass opacity (grade 1), 9 patients (45%) were classified as grade 2, 7 patients (35%) presented with focal consolidation, with or without elements of fibrosis (grade 3), and only one patient (5%) presented with opacity with accompanying atelectasis and loss of pulmonary volume (grade 4). Both univariate and multivariate analysis revealed as prognostic factors for the radiological grading of RP the reduction of FEV1 and the V20 (P=0.026 and P=0.003, respectively). There was also a significant (P<0.001) correlation of radiological grading of RP with FEV1 and V20 (spearman rho 0.92 and 0.93, respectively). Conclusions: The high correlation of the proposed radiological grading with the FEV1 and the V20 is giving a satisfactory clinical validity. Although the proposed grading scale seems relevant to clinical practice, further studies are needed for the confirmation of its validity and reliability.

The Purpose of this study Gerber company AM-300 system of the automatic system of Producing the original form the automatic system of Producing the original form of "Jogori(a Korean Jacket)' and Grading by the usage of computers and find out its efficiency. In the result, the auther has found out the following facts and became confident on the facts; The AM-300 program of the automatic system enabled to produce the original form of 'Jogori' and Grading fitting in a short time and definately, and which indicated that the automatically producing system of the original form of 'Jorgori' and Granding is efficient. Even in the aspect of education, it has been acknowledged that there is necessity of using computers, the accumulation of techincs and technology based on traditions by cultivating professional designers, and computerization so that the composition of 'Hanbok' (Korean clothes) should be rational and scientific. In addition, advertisement and education on the traditionalism and superiority of 'Hanblk' are indispensable and absolutely necessary. Also, to succeed folk costumes rightly, the usage of computers is thought to be a way to effectiveness. So far in the study, only the automatic system of producing the original form of 'Jogori' and Grading through computers is emphasized on, however in the future, such an automatic system should be continuously supplemented, studied on and developed even in other various fields such as in pattern making, design, products planning, etc..

The purpose of this study is to develop the size and grading increments chart for the middle-aged obese women compared with normal women in middle age. Seven hundred and thirty three women's data from the 4th National Korean Size Survey for Standardization (1997) were analyzed. It was found that size increment of bust and hip girth of obese women was different from that of ordinary middle-aged women. The rate of coverage for a certain set of size specification and the grading increment value for the clothing of Korean obese women in middle aged group were also suggested. The relative percentage value of grading rule based on the change in bust girth increment of Korean obese women was quite different from that of American women. In conclusion, it was noted that the characteristics of the body size specification of obese women was quite different from those of the corresponding age group, so that the separated size specification and grading rule are needed to be used in the manufacturing process of obese women's clothing.

Even though computer based college lecture management system was developed long ago and has been used ever since, developing perfect lecture management is not simple. The main objective of this system is to develop appropriate online lecture supportive management program suitable for college lectures. This system [ADLEMS] mainly focuses on the management of college database lectures, exams, and grades. This system supports management and grading of attendance, reports, quizzes, mid-term, and final exams. Exam management categorizes into multiple choice questions, essay questions, short answer questions, and SQL. Especially for SQL, division analysis was applied when developing grading system for more effective grade management. For essay questions and short answer questions, manual [hand] grading method was used. Every student can verify the grading process in person to alleviate the problems occurring during the grading process.

InSb 물질은 다른 III-V족 물질들과 비교해서 bandgap이 낮고 전자 이동도가 높아, 소자 구현 시 낮은 전압으로도 고속 동작 특성을 제어할 수 있다는 장점이 있다. 그러나 Si, GaAs 또는 InP 등 쉽게 구할 수 있는 기판과 격자 부정합이 커서 상기 기판에 성장시 많은 defect가 존재하는 단점이 있다. 그러므로 이를 상기 기판에 성장하는데 meta-morphic이라 불리는 성장 기술이 요구되는 어려움이 있다. 본 발표에서 Semi-insulating GaAs 기판위에 고품질의 InSb 박막을 성장하기 위해 grading buffer technique을 도입하며 이에 대한 여러 가지 비교실험과 함께 최적의 성장 방법과 기술에 대해 논의 한다. GaAs와 InSb 물질사이의 bandgap과 격자 부정합을 고려하여 AlSb 물질을 먼저 성장하면서 동시에 InxAl1-xSb로 변화를 주어 InSb 박막이 성장되도록 하였다. ($x=0{\rightarrow}1$). 성장 온도 변화 및 In과 Al의 조성비에 변화를 주어 grading 기법으로 성장하였고 상기 grading buffer위에 InSb 박막을 0.65um 성장하였다. $10um{\times}10um$ AFM 측정결과 2.2nm 정도의 표면 거칠기를 가지며 상온에서의 전자 이동도는 약 46, 300 cm2/Vs 이고 sheet electron density는 9.47(e11) /cm2의 결과를 확인하였다. 실험결과 InSb 박막을 올리는데 있어 가장 고려할 사항인 GaAs 기판과 InSb 박막 사이에 존재하는 격자 부정합을 어떻게 해결하는가에 대해서, 기존의 여러가지 방법과 비교해서 grading buffer 기술이 유효하다는 것을 증명하였다.
