Myelodysplastic syndrome(MDS) is a group of acquired conditions characterized by progressive bone marrow failure associated with normocellular or hypercellular bone marrow that cannot be attributed to nutritional deficiency, chronic infection, or other chronic systemic illness, and cannot be reversed by the successful treatment of those conditions. Whereas the cases of secondary MDS occur at all ages, primary MDS is essentially a disease of elderly, though no age group is exempt and predomonant in men. The MDS is fundamentally clonal disorders at the level of the haemopoietic totipotent stem cell. Clinically, they are characterized by varing degrees of peripheral cytopenia(s) with morphological and functional abnormalities of blood elements. We have experienced two unrelated pediatric cases, who showed pancytopenia on admission and the characteristic marrow findings of MDS. The first case, a 12 months-old girl, showed increased reticulin with abnormal localization of immature precursor cells(ALIP) in her bone marrow, in addition to dysplastic features such as bi-and multi-nucleation of late normoblasts and internuclear bridging. She also showed 22% of blasts in her bone marrow cells thus classified in the category of RAEB-t after FAB classification. Also found were a chromosomal abnormality namely 46 XX t(14q21q), which was an unusual one. Her family brought her home and, 4 month later, she deceased. The second case, a 12 year-old boy, showed pancytopenia with Pseudo-Pelger-Huet anomaly in neutrophils but no blasts in the peripheral blood. Bone marrow of this case also showed the picture of dyserythropoiesis with binuclearity, internuclear bridging, nuclear fragments, multinuclearity of late normoblasts, in addition to megaloblastoid change in the normoblasts and increased mitosis in granulocytic series. No chromosomal abnormality was found. Classified as RA after FAB classification of MDS. Showed good response to conservative management for anemia for more than one year.

This study investigated the effect of porcelain primer on bonding of composite resin to porcelain surface. In order to test the bond strength between porcelain and composite resin, porcelain cylinders were embedded in acrylic resin, and polished with 240grit silicone carbide paper. The specimens were divided into twelve groups. All specimens were treated with three porcelain primers and bonded with five composite resins. All test groups were stored in 37℃ distilled water for 48hours. Shear bond strengths were measured with Instron(Model 4201) at a cross-head speed of 1㎜/min. The obtained results were as follows : 1. Scotchprime/SiluxⅡ group and BISCO Porcelain Primer/Bisfill group showed significant higher bond strengths than Clearfil Porcelain Primer/Photo clearfil Bright group(p<0.05). And there was no significant differences in bond strengths between Scotchprime/SiluxⅡ group and BISCO Primer/Bisfill group(p>0.05). 2.

본 연구의 목적은 동국대학교의 교수들이 수행하고 있는 교수학습 방식을 파악하고 각 방법들의 효과성을 교수들이 어떻게 인식하고 있는지를 알아 보고자 하였으며 창의적 교수학습방법개발에 대한 교수들의 요구를 파악하여 교수학습개발센터의 프로그램개발을 위한 기초자료로 삼고자 하였다. 수업방식에 있어서 전공, 교양을 막론하고 대부분이 강의식 수업방식이 높았으며(80.9%, 86%), 발표식, 토론식이 (14%, 18.6%) 실험실습 등이 그 다음으로 나타났다. 교수들은 전공과목보다는 교양수업에서 학생들의 요구에 맞는 수업 수업방식을 고려하고 있는 반면 수업방식의 효과에 대해 53%만이 효과적이라고 보고하고 있다. 교수들도 효과적인 강의방법 등 교수법에 대해 체계적으로 학습할 필요성을 느끼고 있었다. 강의 기술(교수방법)과 토론 중심 수업 방법에 대한 워크샵에 대한 요구가 가장 높게 나타났고 발표수업과 프로젝트수업 방법 등 강의식 수업 이외의 다른 수업방식에 대한 워크샵 요구도가 높았다. 그 외에 학교의 지원에 대해서는 첨단 수업 기자재 활용을 위한 보조자(조교)에 대한 요구도가 가장 높고 강의 운영을 위한 보조금, 개인별 상담 지원 순으로 요구도가 높게 나타났다. The purpose of this study was to comprehend the methods of teaching and learning carried out by the teachers of Dongguk University, and to find out how the professors found those methods effective. This research was also used to serve as a basis for the development of a more creative teaching-learning system to enhance better programs for the Professor Teaching-Learning Development Center. In teaching methods, regardless of classes for majors or for cultural enrichment, most of the courses were in the form of lectures (80.9%, 86%) followed by research and discussion (14%, 18.6%), with experiment and practical training coming in third. Although professors tend to choose a more student-oriented class method in distribution courses more than in major courses, it was reported that only 53% of the faculty claimed this class method to be effective. The faculty felt the need for professors to have more constructive learning in incorporating more effective teaching methods. The demand for professor workshops on teaching skills (teaching methods) and discussion oriented classes proved to be high, as well as the need for workshops on teaching methods other than lectures, such as research courses and project oriented class methods. Regarding other demands for university support, the demand for an assistant (assistant teacher) to help with the new technology equipment was the highest, followed by subsidies for course management and support in individual counseling.

The microstructural evolution of b-NiAl/γ' -Ni3Al two-phase (Ni_(66)Al_(34))_(100-x)X_(X)(X=Ti, Si, Nb) alloys during various heat treatment (quenching and aging) were systematically studied. It was found that the microstructural features of the two-phase NiAl/Ni₃Al alloys could be divided into three types : lamellar, mesh and Widmansttten microstructures. The reason why those three types of microstructure were formed could be explained by the change of austenite start temperature(As temperature) depending on the ternary elements. In case of As>250℃, the lamellar microstructure was formed by following phase transformation: Martensite→Ni5Al3→β+γ' . In this case, the NiAl martensite was quickly transformed into the Ni5Al3 phase at 250℃ by a re-ordering reaction. In case of 20℃ <A_(s)<250℃, two types of mesh microstructure were formed depending on the ternary element. When Ti and Nb were added as a ternary element, the β→Ni_(5)Al3 transformation occurred very quickly, but not in the case of Si addition. Hence, the final mesh microstructures showed somewhat different microstructural features. On the other hand, in case of A_(s)<20℃, the direct β→β+γ' transformation occurred because the martensitic transformation could not occur due to its very low M_(s) temperature, resulting in the Widmanstatten type microstructure.

The purpose of this study was to examine the value orientations of sport as perceived by the youth and college student. Specifically, the purpose was to investigate whether differences on selected sport values were significantly related to gender, age, and sport participation. Subjects were 1561 students(830 male and 738 female),using sysytimatical cluster sampling, from the six secondary schools and one university in Cheju. Data for the study were collected via 10 items qestionnaire. A 5-point Likert scale, strongly disagree( 1 )-strongly agree(5), was used to measure the value orientation of sport. Sufficient internal reliabilty(Cronbachs Alpha=.84) was found for the items comprising this scale. Frequencies and one-way ANOVA were used for statistical analysis. The subjects viewed the following values acquired from the sport participation to be most important: improvement of physical fitness, good citizenship, a vehicle of social development, competition in good faith and coorperation, self-discipline, cultivation of fair play. The results indicated that gender, age and level of sport participation had a significant effects on value orientation of sport. Specifically, the gender result showed that male students perceived significantly higher level of all values of sport than did female students. The age result indicated that, for the male students, junior school students perceived significantly higher level of respect for authority than did other groups, while college students perceived significantly higher level of patriotism, self-discipline, and leadership, and physical fitness than did junior & high school students. With respect to female students, junior school students perceived significantly higher level of cultivation of competition in good faith & coorperation, respect for authority, and fair-play attitude scores than did other groups. The sport participation results revealed that, for the male students, high-sport participants expressed significnatly higher levels of all sport values(socia1 development, good citizenship, competition in good faith and coorperation, respect for authority, patriotism, social mobility, fair play, self-discipline, leadership, and physical fitness)than did low-sport participants. For the female students, high-sport participant expressed significnatly higher levels of social development, competition in good faith and coorperation, respect for authority, social mobility, fair play, self-discipline, and leadership values than did low-sport participants. Overally, the findings of this study indicated that sports are perceived in positive terms from the youth and college students.
