유방의 과립세포종양은 슈반세포에서 기원하는 아주 드문 질환이다. 대부분의 환자들은통증을동반 하 지 않는 경성의 유방 멍울을 주소로 내원하게 된다. 따라서 이학적 진찰상 유방암과의 감별이 필요하 다. 유방의 과립세포종양은 임상적으로 유방암과 매우 유사하지만, 98%에서 양성 소견을 보인다. 일 반적인 유방촬영술 및 유방초음파 상에서는 종양 특이적인 소견을 보이지 않으며, 오직 조직생검술을 통한 조직학적, 면연화학적 검사만이 병변을 확진 하는 방법이 된다. 51세 여자 환자가 유방에 만져 지는 멍울을 주소로 외래를 방문하였다. 이학적 검사 상, 좌측 중간외측 유방에 멍울이 만져졌으며, 대흉근 및 주변조직과 고착 되어있는 소견을 보였다. 유방단순촬영 상 좌외측 유방에 비대칭성이 보 였다. 유방 초음파상 1cm크기의 유방 뒤 지방층을 침범하는 종괴가 보였다. 중심 침 조직검사 상 유 방의 과립종양세포 소견을 보였으며, 조직 절제 생검으로 확진 하였다. 임상적으로 유방암과 많이 혼 돈되는 과립세포종양 1예를 보고하고자 한다.

Gastric small cell carcinoma(SCC) is defined as poorly-differentiated neuroendocrine tumor of the stomach, and their morphologic and biologic features arc similar to those of the lung. It is known that this tumor has poor prognosis even in early pathologic stage, It acounts for only 3% of all gastrointestinal SCC. that has been reported only 33 cases outside and 6 cases inside of the comitiy. Most of these reports are related to advanced gastric SCC. as pathologic stage IIIb or IV. This report describes a case of early gastric SCC. pathologic stage Ib.

고농도 도핑된 n+-Si 영역상에 Co/Ti 이중막 실리사이드의 형성과 특성연구

장지근,신철상 단국대학교 1999 論文集 Vol.34 No.-

We have studied the formation of Co/Ti bilayer silicide with low resistivity and good thermal stability on the heavily As doped n^+-Si region. In this paper, Co/Ti bilayer silicides were fabricated by depositing Co(150Å)/Ti(50Å) films on the As-implanted n^+-Si region in an E-beam evaporator and performing the two step RTA process (first annealing:650℃/20sec. second annealing:800℃/20sec) in a N_2 ambient with the pressure of 10^-1atm, Co/Ti bilayer silicides obtained from our experiments exhibited the low resistivity of about 19μΩ-㎝ and the uniform thickness of about 500 Å without increase of sheet resistance and occurrence of agglomeration under the long post-annealing time up to 1000℃.

Difference data are very useful for a prediction system because they can reveal the characteristics of non-stationary time series. Also, they can protect fuzzy clustering from a biased situation toward one side among fuzzy sets. But it is not easy to determine optimal difference intervals revealing patterns and regularities of time series. To overcome this problem, this paper proposes the data preprocessing procedure based on correlation analysis. Then, multiple model fuzzy systems are constructed by using the determined optimal intervals. To reflect the performances of each fuzzy system, this paper also proposes the adaptive model selection technique. The proposed technique can improve the prediction quality of fuzzy system that depends to the characteristics of input data because it is possible to control system output corresponding to system input via the adaptive model selection rules based on rough set theory. Thus, the proposed methods are more effective for prediction of non-stationary and/or chaos time series than traditional methods. In simulation and conclusion section, this paper verifies that the prediction performances of the proposed methods are very good and that the proposed methods are very effective to control the hybrid systems or multiple systems.

CMOS VLSI의 IDDQ 테스트세트 간략화에 관한 연구

김강철,송근호,한석봉 진주산업대학교 1996 論文集 Vol.35 No.-

This paper proposes a dynamic compaction algorithm which can detect intra-bridging faults for IDDQ testing in CMOS VLSI. X_gates which have X(don't care) values in the input of the gate may exist in the circuit after a test pattern in chosen. The compaction algorithm assigns the logic value 1 or 0 that can be applied to the primitive fault pattern to X in the X_gate, and it detects all detectable faults for a test pattern. The simulation results in the benchmark circuits show that the fault coverage of this dynamic compaction algorithm is much enhanced compared with the conventional static compaction algorithms, and the resulting test vector reduction is up to 30%.

The purposed of the study was to investigate pulmonary function on endurance athletes including marathon runners, cyclists, and swimmers. The results were compared to predicted values which based on physical condition, such as body height and weight etc. The subjects were 11 marathon runners including 2 national Caliber runners, 17 cyclists including 8 national caliber cyclists, and 3 male and female caliber swimmers. The results were summerized as follows: 1). In case of marathon runners,actual values of FVC, RV,TLC,RV/TLC, and D?? , were shown higher than predicted values, invesely actual value of FEV/FVC, MVV, D??/V?? were shown lower than predicted values, and K's C (permeability) was shown significant lower than predicted values(p<0.05). 2). In case of cyclists, actual values of FVC, FEV/FVC, and D?? were shown significantly higher than predicted values (p<0.05), and actual values of RV, TLC, and RV/TLC were much more than predicted values, invesely actual values of MVV, and DL/VA were shown lower than predicted values, and K' sC was shown the same tendency with case of marathon runners(p<0.05). 3). In case of male swimmers, actual values of FVC, RV, TLC, and RV/TLC were shown higher than predicted values especially with FVC was higher than others (p<0.05), and actual values of FEV/FVC, MVV, D??, D??/V??, and K's C were shown lower than predicted values, especially FEV/FVC and K??s C were lower than others (p<0.05). In case of female swimmers, actual values of FVC, RV, RV/TLC, and D?? were shown higher than predicted values, and FVC was shown the same tendency with male swimmers. Actual values of FEV/FVC, VV, D??/V??, and K'sC were lower than predicted values, especially K'sC was lower than others (p<0.05). 4). To be compared with marathon runners and cyclists, cyclists were higher than marathon runner with age and body height, and there were no significant differences among the tested items but in terms of MVV, D??, and V?? were shown that cyclist were higher than marathon runners. 5). To be compared with national caliber and university or college caliber elite athletes, in case of marathon runners, national caliber athletes were shown higher level in eacg tested items except alveolar ventilation (V??) than university of college caliber elite athletes, and in terms of cyclists, national caliber athletes were shown higher level than university or college caliber elite athletes in each tested items except FVC, FEV/FVC, and D??.

이성근,김효종,박철민 東亞大學校 海洋資源硏究所 1990 硏究論文集 Vol.3 No.1

Fatigue life of base and weld metal of 0.17C-Ni-Cr-Mo alloy steel have been investigated in synthetic seawater under smooth and notched conditions at frequencies of 4Hz and 30Hz. Most data for the alloy steel agree with that for HY-100 steel. The form of a simple power relation can be suggested as a conservative design criteria for the fatigue life in aggresive environments.

이근철 仁川敎育大學校 1992 論文集 Vol.26 No.1

This study aims to develop an integrated curriculum for moral discipline in primary school. For this, following topic have been dealt with; 1) What becomes the Justification of integration curriculum for moral disciplione. 2) What are the proper methods for the integration curriculum management of moral discipline. 3) Moral discipline strategies in curriculum have been seek for. The resulted are as follows respectively. 1) In view of moral education, morality includes only approximative, cognitive and affective domain, Hence, we become much more sensitive to the motion of the nonformal or hidden curriculum as a factor in moral education. For proper moral discipline, every viewpoint should be gathered and selected to be moral Values in curriculum, For the same reason, in order to have such moral discipline that would become a curriculum integeration. 2) As for the thereby reguired methods of integration curriculum of moral discipline, multi-disciplinary or inter-disciplinary integration methods base on concepts in the value of eduction were pursued and apoproached. 3) For moral discipline strategies, reconstruction and selected values in curriculum. Namely, values in learning language, social studies, mathematics education, art, physical education, home economics teaching. 4) Therefore, moral education ultimately is realized in activities, program that are reasonably accessible, interestion to students, and offer some promise of success. The integrated curriculum management for moral discipline must also deal with the nature of the moral principles proposed; How the values will be used, the relation of the topic of moral education to other subjects in the curriculum.
