金慶澤 대구교육대학교 1968 論文集 Vol.4 No.-
Instruction of teachers aim at expediting and improving the learning of the maladjusted children to attain a high level of intelligence, sociability, physical conditions, character and emotion. Directing them is the duty of the teachers and has been a subcurrent problem in the guidance of their study and living. In light of the cause analysis, devided largely into two parts, for the maladjusted children, a study was made both on the subjective conditions (or character consititution) such as intellect, physique, character, emotion, basic scholarship and psychological habit of lesson and on the effect of the dynamic human relation and psychological factors in the objective conditions (or environment constitution) such as family, class and school, society on the growth of the children. According1y, attention should be invited to diagnose the causes and find ways of instruction. So the important matters and instruction methods for the maladjusted children in lesson were concretely studied.

The objectives of this study are to provide present situation of Kujwa Agricultrual and Industrial Complex in Cheju Island and to suggest the direction of efficient and systematic development. Fulfilling the two research objectives depends on obtaining data from the firms' employee and employer in that area. In order to obtain the very datailed information for this study it was necessary to gather data by a survey. After analyzing the data we have reached the conclusion. Efficient and systematic development approaches suggested are as follows : 1) Train unskilled people to create employment in this area, 2) In order to maximize employment effect in the area it is necessary to strengthen the selection of the firms, 3) Adopt a rigorous environmental policy to conserve higher environmental quality levels, 4) It is required for the government to invest more capital for harbor facilities, 5) Need to develop a technique and to improve productivity, 6) Establish networks of information to communicate from one area to another, and 7) Improve employees' welfare.

목적: 후방 십자 인대의 골편을 포함하지 않은 대퇴 부착 부 견열 손상에 대한 관절경적 일차 봉합술의 추시 결과를 보고한다. 대상 및 방법: 1993년 1월부터 2002년 12월까지 본원에서 관절경적 후방 십자 인대 봉합술을 시행한 13례 중 2년 이상 추시가 가능했던 10례를 대상으로 하였으며 평균 추시 기간은 $38.7{\pm}11$개월이었다. 평균 나이는 $28.2{\pm}6$세로 남자 8례, 여자 2례였다. 모든 예에서 최종 추시 시 Lysholm and Gillquist 점수 및 International Knee Documentation Committee(IKDC) criteria를 이용하여 평가 하였으며, 후방 전위 검사로 후방 불안정성을 평가하였으며, 후방 부하 측면 방사선 사진으로 경골의 후방 전위를 측정하였다. 결과: Lysholm and Gillquist 점수는 평균 $94.5{\pm}2.6$, International Knee Documentation Committee criteria에 따른 결과는 4례에서 A(normal), 6례에서 B(nearly normal)이었다. 후방 전위 검사 상 5례에서 grade I의 후방 불안정성을 보였으며, 5례에서 grade II의 후방 불안정성을 보였다. 후방 부하 측면 방사선 사진에서 경골의 후방 전위는 평균 $3{\pm}2.3mm$ 이었다. 결론: 후방 십자 인대의 골편을 포함하지 않은 대퇴 부착 부 견열 손상에 대한 관절경적 일차 봉합술은 후방 불안정성을 줄이고 기능적 회복을 향상시키기 위해 유용한 방법으로 사료된다. Purpose: The purpose of this study is to evaluate the results of arthroscopic primary repair of a posterior cruciate ligament(PCL) avulsion injury without bony fragment at the femoral attach site. Materials and Methods: From Jan. 1993 to Dec. 2002, we performed 10 cases of PCL repair by arthroscopic suture technique. The mean follow-up period was $38.7{\pm}11$ months and the mean age of the patients was $28.2{\pm}6$ years old. 8 cases were men. 2 cases were women. At last follow-up, all cases were evaluated with the Lysholm and Gillquist knee rating system and International Knee Documentation Committee criteria. Posterior tibial displacement on stress lateral radiograph and posterior instability with posterior drawer test were measured also in all cases. Results: The mean Lysholm and Gillquist score was $94.5{\pm}2.6$. 4 cases were IKDC A(normal) and the other 6 cases were IKDC B(nearly normal). Posterior instabilities by posterior drawer test were grade I in 5 cases and grade II in 5 cases. A mean posterior translation of tibia was $3{\pm}2.3$ mm on stress lateral radiographs. Conclusion: Arthroscopic primary repair of PCL avulsion without bony fragment at the femoral attach site is one of the useful methods that reduce the posterior instability and improve the functional outcomes.
Grayscale Hausdorff 거리를 이용한 문자인식
김경택,경지훈 대한산업공학회 2015 대한산업공학회 춘계학술대회논문집 Vol.2015 No.4
The Hausdorff distance is commonly used as a similarity measure between two-dimensional binary images. Since the document images may be contaminated by a variety of noise sources during transmission, scanning or conversion to digital form, the measure should be robust to the noise. Original Hausdorff distance has been known to be sensitive to outliers. Transforming the given image to grayscale image is one of methods to deal with the noises. In this paper, we propose a Hausdorff distance applied to grayscale images. The proposed method is tested with synthetic images with various levels of noises and compared with other methods to show its robustness.
Stimuli-responsive polymers and block copolymers for smart delivery systems
김경택 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.0
Stimuli-responsive polymers and block copolymers change their chemical and physical properties in response to external stimuli. Of particular interest is to synthesize polymers that respond to biological stimuli in physiologically relevant conditions, which might enable to design and create new smart delivery vehicles and sensors. We have been studying organoboronic acid-containing polymers and block copolymers as glucose-responsive materials. We will discuss the synthesis and self-assembly of these block copolymers, and also suggest self-assembled nanostructures of boronic acid-containing block copolymers as self-regulating delivery vehicles and sensors.
