The formation of tungstic acid a nd the growth of tungsten oxides (mainly trioxide) by firing were studied with electronmicroscope, X-ray powder method and B. E. T. method. A white precipitate of tungstic acid was observed from an ammonium tungstate solution when dilute hydrochloric acid was used, on the other hand a yellow precipitate tungstic acid was obtained wnen concentrated hydrochloric acid was used. X-ray analysis showed that the crystal structure of the white tungstic acid was different from that of the yellow tungstic acid. The particles of white tungstic acid were smaller than those of yellow tungstic acid. Yellow tungstic acid obtained from calcium tungstate had the largest particle size, and was in a state of a spherical aggregate composed of needle crystals resembling to the calcium tungstate particles. These precipitates and ammonium paratungstate crystals were fired at various temperatures, 300, 400, 500, 600, 800, 1000 and 1230℃ for 2 hours. In electronmicroscopic method and B. E. T. method it was found that the sizes of particles were affected by the sizes and crystal structures of the tungstic up to 400℃. At 800℃ the particle size observed in the electronmicroscopic method was slightly affected by the particle size of the tungstic acid, whlie the specific surface measured by B. E. T. method had the same values. In the case of precipitate containing a trace of potassium, the growth of the praticles was promoted at all temperatures. The particles obtained from white tangstic acid, calcium tungstate and ammonium paratungstate were uniform in their size, but the particles from yellow tungstic acid were not uniform. When ammonium paratungstate was decomposed in vacuum, tungsten oxide was produced, the growth of the particles was quite different from that of tungsten trioxide particles.

Employing mercury and oil this maometer could make the measuring of the pressure about ten times preciser than the mercury manometer. Carbon dioxide and nitrogen were used as the adsorption gas, By this apparatus even the specific surface area which is as small as 01.~0.5㎡, could be measured to the third order of the significant figure.

올림피즘(Olympism)의 實體論的 考察

安永弼 東亞大學校 大學院 1987 大學院論文集 Vol.12 No.-

The modern Olypics, which was revived in 1896 after the lofty spirit of the ancient Greek Olympic games, is troubled with many problems in various aspects. In view of the current situation, however, we need to ponder on the authentic meaning of Olympism so as to illuminate the future Olympics. This research, therefore, was focused on supplying materials of data helpful to eradicate various difficult problems, such as the fall of amateurism and Olympism damaged with polarized political thoughts and commerecialism. The epitome of Olympism, according to French Baron Pierre de Coubertin, the initiative founder of the contemporary Olympic Games, can be outlined as follows:perfection of human personalities based on every0inch amateurism and fair knight-hood, while securing world peace through the sports activities. As time changed, however, Olympism has begun to be rotten. Besides the problems pinned above, there are stubborn nationalism in choosing the host country of the Olympics, victory-first-by-all-means idea and so forth, Centering on the thoughts of Professor J.A.Lucas, who courageously suggested the systemic change of the Olympics, the researcher attained the following conclusion. 1. In consideration of the avrupt changes of the times and the Olympics itself, amateurism should be fully weighed, especially on the part of each participating athlete's qualification. 2. Diminshing collective sports and nation-oriented ceremonies as most as possible will maintain the fundamental idea of Olympoism by possibly keeping from nationalistic political influence. 3. enormous cost of holding the Games, excessive commercial war to advertise each enterprise, show-off of the up-to-date technologies, and harmful effects resulting from the choice of a host country will be probably lessened by holding the Olympics in one place for good. In all, thought the drastic reform of the Olympic system which seems more urgent than any other man-made one, the peaceful international athletic festival of the Olympics should enjoy prosperity, raising its quality and contributing to the enhancement of man's dear spiritual values of education, beauty, social ethics and so on.

As society has been changing rapidly, so the evaluation of women's position and the value of leisure has been changing. Women's demanding of leisure activities is also increasing today. I studied on the factors which have effected on the satisfaction of leisure time's married women in cities with involvement of leisure and sports activities. The results are as follows ; 1. Married women's leisure and sports activities by ages & educational level. (a) As for married women in cities, the older they are the more they took experiences in sports activities for a year. I think it is desirable but in health care it is concerned that young married women in cities don't take part in sports activities. (b) The higher their ages are, the more time is required for exercise in a time. (c) The old age group at 60s expressed the most active attitudes in joining sports clubs. (d) The young age group of 20s preferred to join clubs in their work and public centers while the old age group of 60s, 88.9%, definitely prefered to join clubs in public centers. (e) In the joining sports clubs, married women in 30s will was highest, while the old age group of 60s and over was lowest. (f) In the last one year, housewife participating in 20s was comparatively lower. (g) In the satisfaction of leisure time, the old age group of 60s and over was highest while the young age group of 20s was lowest. That is, the more ages were highter the more the satisfaction of leisure time was. (h) In the percentage of participating in sports activities in the last one year, the married women who finished only middle school was highest, 95.7%, So the higher educational level is the lower the percentages of that is, (i) In the time required, the higher educational level is, the shorter the time became. (j) In the facilities, many married women who finished university used them in their works or schools, or public centers. (k) In the time of moving to the facilities, there was little difference in educational levels, but the time of married women who finished university was less than others. (l) In the participating in several lectures, the higher educational level was, the higher the percentage was. (m) In the satisfaction of leisure time, the higher educational level was, the lower the percentage was, So I don't think the programs and condition of leisure and sports activities satisfy married women of high educational level. 2. The list of factors which have effected on the satisfaction of leisure time, are as follows ; (a) the attitudes of leisure time or sports activities, (b) the result of leisure time or sports activities(treatment for hypochondria and anxiety) (c) the result of leisure time or sports activities(treatment for shoulder pain and backache, and relief of worries) (d) the time required in a time. (e) confidence of body activities (f) the result of leisure time and sports activities(they got confidence and satisfaction) (g) the frequency of participating in leisure and sports activities in the last one year. (h) the result of leisure time and sports activities(they became to be friendly with and became kind to others) (i) the result of leisure time and sports activities(they became to plan their life-styles actively) (j) health condition. From these lists I could understand the most important factor is the body activity-oriented leisure time activities of married women in cities.

The data were analyzed through analysis of variance(ANOVA) and multiple classification analysis(MCA). The findings obtained from this study were followings. First, the participation duration in sports has a influence on the psychological, relaxational, and physiological satisfaction but has no influence on the educational, social, and environmental satisfaction. Second, the frequency of sports participation has a influence on the leisure satisfaction. That is, there is difference in psychological, educational, social, relaxational, physiological, and environmental satisfaction according to the frequency of sports participation. Third, the participation of sports club has a influence on the leisure satisfaction. That is, there is difference in psychological, educational, social, relaxational, physiological, and environmental satisfaction according to the participation and non participation of sports club.

딥러닝 기반 임의적 스케일 초해상도 모듈을 이용한 Mask-RCNN 성능 향상

안영필,박현준 한국정보통신학회 2022 한국정보통신학회논문지 Vol.26 No.3

In instance segmentation, Mask-RCNN is mostly used as a base model. Increasing the performance of Mask-RCNN is meaningful because it affects the performance of the derived model. Mask-RCNN has a transform module for unifying size of input images. In this paper, to improve the Mask-RCNN, we apply deep-learning-based ASSR to the resizing part in the transform module and inject calculated scale information into the model using IM(Integration Module). The proposed IM improves instance segmentation performance by 2.5 AP higher than Mask-RCNN in the COCO dataset, and in the periment for optimizing the IM location, the best performance was shown when it was located in the ‘Top’ before FPN and backbone were combined. Therefore, the proposed method can improve the performance of models using Mask-RCNN as a base model. 인스턴스 분할에서 Mask-RCNN은 베이스 모델로 자주 사용된다. Mask-RCNN의 성능을 높이는 것은 파생된 모델에 영향을 미치기에 의미가 있다. Mask-RCNN에는 입력 이미지 크기를 배치 크기로 통일시키는 변환 모듈(transform module)이 있다. 이 논문에서는 Mask-RCNN의 성능 향상을 위해 변환 모듈의 크기 조정 부분에 딥러닝 기반 ASSR(Arbitrary-Scale Super-Resolution)을 적용하고, 스케일 정보를 모델의 IM(Integration Module)을 이용하여 주입한다. 제안하는 방법을 COCO 데이터세트에 적용하였을 때 인스턴스 분할 성능이 Mask-RCNN 성능보다 2.5 AP 높았다. 그리고 제안하는 IM 위치 최적화를 위한 실험에서는 FPN(Feature Pyramid Network)과 백본(backbone)이 결합하기 전의 ‘Top’ 위치에 배치했을 때 가장 좋은 성능을 보였다. 따라서 제안하는 방법은 Mask-RCNN을 베이스 모델로 사용하는 모델들의 성능을 향상시킬 수 있다.

The effects of $MnO_2$ and $Cr_2O_3$ on the Piezoelectrictric properties of Pb(Mg1/2W1/2)0.3 Ti0.4 Zr0.3O3 Ceramics. Electromechanical properties in the system in connection with the sintering temperature and the effects of $MnO_2$ and $Cr_2O_3$ addition. The dielectric constant of the ceramics decreased with the additions of $MnO_2$ while the additions of $Cr_2O_3$ increased the value. The Planar coupling factor (Kp) of the ceramics with 0.2wt% $MnO_2$ and with 0.2wt% $Cr_2O_3$ gave the highest value of 0.52 and 0.513 as sintered at 106$0^{\circ}C$, 108$0^{\circ}C$, respectively. The value of mechanical Q-factor were in parallel with the fired density of the ceramics. The optical micrography of the sintered bodies showed that the additions of $MnO_2$ promoted the grain growth, while the additions of $Cr_2O_3$ retarded the grain growth.
