The diagnosis of papillary thyroid cancer is generally based on the findings of intranuclear cytoplasmic inclusions and nuclear grooves. Although anisokaryosis and poikilokaryosis, in papillary thyroid cancer, are not distinct when compared to other cancers, cytological examination can provide useful preoperative information. Our study evaluated the diagnostic role of computer-assisted image analysis for the pre-surgical assessment of papillary thyroid carcinoma. Thyroid aspirates from twenty female patients who were histologically confirmed to have both papillary carcinoma and benign nodules were studied. Different populations of 50 benign cells and 50 malignant cells were analyzed. Five morphometric parameters were selected for analysis: nuclear area, perimeter, maximum length, maximum width and intensity standard variation. The values obtained for papillary carcinomas were higher than the surrounding benign nodules as follows: nuclear area 63.5 vs. 36.1 (p=0.000), nuclear perimeter were 29.4 vs. 22.0 (p=0.000), maximum length 9.6 vs. 7.1 (p=0.000), maximum width 8.2 vs. 6.3 (p=0.000), the ratio between maximal length and maximal width 1.16 vs. 1.13 (p=0.000), the standard variation of intensity 14.9 vs. 15.9 (p=0.101) respectively. Therefore, morphometric information can be helpful for the differential cytological diagnosis of papillary thyroid carcinoma.

This study was conducted to find out the best optimum design method for the design of reinforced concrete agricultural aqueduct abutment and pier structures. The mixed-discrete optimization and continuous optimization method were applied to the design of reinforced concrete agricultural aqueduct abutment and pier and the results of these optimization methods were compared each other. It is proved that mixed-discrete optimization method is more reliable, efficient and reasonable than continuous optimization method for the optimum design of the reinforced concrete agricultural aqueduct abutment and pier.

This study was intended to investigate the effects of bituminous material content of soil-cement mixtures on their durability. For the purpose, unconfined compressive strength test, Freeze-thaw test, and wet-dry test were performed with three types of soil. Each type of soil was mixed with three levels of cement content and each soil-cement mixture was mixed with four levels of bituminous material content. For the unconfined compressive strength test, Freeze-thaw test and wet-dry test, 324, 108, and 108-specimens were prepared respectively. Unconfined compressive strength was measured at age of 7-days, 14-days and 28-days using 108-specimens in each age. The soil-cement loss rate due to freeze-thaw and wet-dry were calculated after 12 cycles of test using 108-specimens in each test. The results are summarized as follows : 1. Optimum moisture content was increased with increase of cement content, but maximum dry density was changed irregulary with increase of the cement content. 2. The unconfined compressive strength was increased with increase of cement content, bituminous material content and curing age. Cement is more effective factor than bituminous material on unconfined compressive strength of soil-cement Mixture. 3. It is estimated as the most economical cement content that the recommended cement content of A.S.T.M. because increasing rate of unconfined compressive strength at age of 28-days was low when cement content is above the recommanded cement content of A.S.T.M. among all types of soil. 4. Although a portion of cement content is substituted for bituminous material, the necessary unconfined compressive strength can be obtained. 5. The soil-cement loss was more influenced by wet-dry than Freeze-thaw 6. The bituminous material is more effective on the decrease of soil-cement loss than increase of unconfined compressive strength 7. The void ratio of soil-cement mixture was changet irregularly with increase of cement content, but that was decreased in proportion to the increase of bituminous material content. 8. The regression equation between the unconfined compressive strength and soil-cement loss rate were obtained as table 7.

In this study, Computer programs for the optimum and automation design of reinforced concrete box culvert were developed. It was shown that even though the starting points and optimization method are different, the objective fuction and optimum design variables converge to a value within a close range respectively, and consequently the optimum design program developed in this study is reliable and strong. 3D-design drawing can be drawn using automation design computer program developed in this study.

서구 유럽 및 일본애니메이션에 비해 짧은 역사를 지닌 한국 애니메이션은 1950년대 후반 광고애니메이션과 문화영화의 일환으로 제작된 비상업용 단편애니메이션으로 출발하였다. 1960년대 영화법과 문화정책이 투영된 문화영화 애니메이션은 한국애니메이션의 역사에서 거의 언급되지 않고 있지만, 극장용 장편애니메이션 이전에 제작된 귀중한 문화 창작물이다. 특히 15초 내외의 짧은 CF애니메이션에 비해 4분에서 10분 내외의 단편애니메이션으로 그 당시 한국애니메이션의 수준을 가늠할 수 있는 사료적 가치가 있는 작품들이다. 1960년대에 20여편의 단편 애니메이션이 제작 되었으며, 주로 근대화 정책추진과정에서 국민들을 계몽하기 위한 교육 내용을 담고 있다. 국립영화제작소에서 문화영화로 제작된 단편애니메이션은 셀을 활용한 카툰애니메이션 이외에도 페이퍼애니메이션, 퍼핏애니메이션도 제작되었다. 이러한 배경에서 본 논문은 1960년대에 국립영화제작소에서 제작된 단편애니메이션에 주목해보고자 한다. CF 이외에 초기 단편애니메이션의 연구가 거의 없는 상태에서 작품의 발굴과 분석은 의미 있는 일이라 생각하며, 이 창작과정에 참여했던 박영일감독, 한성학감독, 정도빈감독, 신동헌감독, 넬슨신감독 등이 이후 극장용 애니메이션 감독으로 활동하였기에 그 작품에 대한 분석은 한국애니메이션을 이해하는 중요한 기반 연구가 될 것이라고 본다. 논문에서는 국립영화제작소 창설의 시대적 상황 및 1960년대 국립영화제작소에서 창작된 단편애니메이션 중 감독 등 참여인력을 확인할 수 있는 10편의 작품을 중심으로 서사적 의미와 조형적 특징을 연구해보고자 한다. 이를 통해 그간 한국애니메이션역사 연구에서 간과된 비상업적 단편애니메이션에 대한 고찰과 향후 한국애니메이션사에 대한 보다 풍부한 연구가 진행되는 단초를 마련해보고자 한다. The Korean animation that has relatively short history compared to the Western Europe and Japan"s animation started out from the non-commercial short-piece animation produced as part of advertisement animation and culture movie in the later part of 1950s. In 1960s, the culture movie animation reflecting for the Movie Act and cultural policies has hardly been mentioned in the history of Korean animation, but they are the precious cultural work produced prior to the theatrical long-piece animation. In particular, compared to the 15-second short CF animation, the short-piece animations are ranging for 4 minutes to 10 minutes as the work pieces with the historic value to measure the level of the Korean animation at that time. in 1960s, approximately 20 short-piece animation works were produced and they contained the educational contents to enlighten general public in the process of modernization policy. Those short-piece animations produced in cultural movie at the National Film Production Center of Korea had been produced not only in cell-facilitating cartoon animation, but also in paper animation and puppet animation. In this background, this thesis takes a close look to the short-piece animation works produced in the National Film Production Center of Korea in 1960s. While there was almost no studies of early short-piece animation other than CF works, it is meaningful to discover and analyze the works, and, Director Park Young-il, Director Han Sung-hak, Director Jung Do-bin, Director Shin Dong-hyun, Director Nelson Shin and others participated in the creative work process have worked as the animation directors for theater that the analysis on the works would be considered as important fundamental studies to understand the Korean animation. Under this thesis, it is intended to study the historic implication and formative characteristics around some 10 work pieces to affirm participating personnel, including directors, for the short-piece animation created by the National Film Production Center of Korea as well as the situation of time to launch the National Film Production Center of Korea in 1960s. Through this effort, it is intended to come up with the starting point to process enriched researches on non-commercial short-piece animation as well as contemplation on the Korean animation history that have been neglected in the study of the Korean animation history through such effort.
