This study was conducted to identify college students' supportive attitude toward the elderly and their awareness of the socialization of care for the elderly, since they will have the responsibility for and the support of the aged society in the near future. This study was also conducted to analyze the factors which affect the socialization of elderly care, and to contribute to building a care system which promotes ahealthy and happy lifestyle for the elderly. After conducting a survey of 1,100 students from13 universities around the entire country, I have analyzed 1,089 data forms, and omitted 11 data entries which had errors or were not answered. 1. Those surveyed are 1,089 students from 13 universities around the entire country. Regional distributions are as follows : 263 students from 4 universities in Daegu and Kyongsangbuk Do(24.2%), 291 students from 3 universities in Busan and Kyongsangnam Do(26.7%), 272 students from 2 universities in Jeolla Do(25.0%), 263 students from 4 universities in Seoul and Gyeonggi Do. Males are 51.7% and females are 48.3% of these students. 2. Instrumental supportive sense level is high in men and emotional supportive sense level is higher in women. Also emotional supportive sense is higher in groups of those having more family members and coming from agricultural regions. 3. The sense of living with aged parents is higher in those living with grandparents than those living separate. The sense of living with sons and daughters after aging is stronger in the students from the Science and Engineering Departments than in the Social and Human Sciences Departments; also higher for men than women. 4. Recognition of elderly care socialization is higher in those from Social and Human Sciences Departments than from Science and Engineering Departments; higher in the case of upper classmenand aged groups, groups having fewer family members than more family members, and in the case of living separated from grandparents. 5. The factors affecting the sense of living with grandparents were family cohesion and instrumental supportive sense. The factors affecting the sense of elderly care socialization were family cohesion, instrumental supportive sense, and emotional supportive sense. From the results it is concluded that to insure a healthy and happy lifestyle for aged people, elderly care socialization offered by society and the country must provide desirable, appropriate care services based on the centralized support system of the family. In order to do this, we propose that elderly care needs inter-family and inter-generational fusion programs to improve family cohesion and care recognition. Also, elderly care is in urgent need to build a strong Family and Health Welfare System for care socialization.

The purpose of this thesis is to study recognition and attitude between teachers and students about school environmental education. The data for this study were collected by administering interviews with seven hundred sixty three teachers and one thousand six hundred fifty six students, and make comparison between these teachers and students recognition and attitude for the environmental education by use of research are as follows. The conclusion of this research are as follows. First, In the study of teachers and students recognition and attitudes about environmental education, though they are interested in it, they lack in knowledge and ability to solve real environmental problems. Also, environmental education tends to be dealt with indifferently and formally because of the burden of entrance examination and lack of material concerned. Second, the recognition and attitude of the teacher-student group about the school environmental education have meaningful difference in each region. The suggestions for the improvement of the environmental education based on these conclusions are as follows. First, the more efficient methods and materials of the school environmental education must be developed in order that students may understand the complex property of the environment and at the same time have the ability to improve the environmental quality. Second, the cooperating system of environmental education including the teacher- student- student's parents' should be established in order to develop the recognition and attitudes for the environment. And also for teachers group to get the more professional leadership about environmental education, government' support is needed.

본 논문에서는 패턴 인식의 전형적인 경우인 보이기 기반 물체 인식(Appearance based object recognition)을 수행하기 위하여, 일반적인 퍼지 분류 모델과, 서포트 벡터 머신을 하이브리드(hybrid) 하게 연결한 서포트 벡터 기반 퍼지 분류 시스템이라는 새로운 방법을 제안하고 이에 대하여 연구한다. 일반적인 분류(classification)문제의 경우 두 클래스로 구분하는데 최적의 성능을 가지고 있는 서포트 벡터 머신이 다중클래스(Multiclass)의 경우 발생 하는 계산량의 증가 문제를 해 결하기 위하여 다중 클래스 분류(Multiclass classification)에 장점을 가진 퍼지 분류 시스템을 도입, 서포트 벡터 머신에 연결함으로써 단점을 보완하는 시스템을 제안한다. 즉 서포트 벡터 머신을 통해 퍼지 시스템의 구조를 러닝(learning)하는데 사용하여 최종 적으로는 퍼지 분류 시스템(Fuzzy Classifier)이 나오도록 하는 것이다. 이 시스템의 성능을 확인하고자 여러 가지 물체들에 대한 이미지를 가지고 있는 COIL(Columbia Object Image Library) 데이터 베이스를 사용하여 보이기 기반 물체 인식(Appearance based Object Recognition)을 수행 하였으며 이를 순수한 서포트 벡터 머신만을 이용하여 물체 인식을 수행한 경우와 정확도 및 인식 시간에 대하여 비교하였다.

In this paper, we present a method for performance enhancement of the marker detection system by using SVM(Support Vector Machine) and LDA(Linear Discriminant Analysis). It converts the input image to a binary image and extracts contours of objects in the binary image. After that, it approximates the contours to a list of line segments. It finds quadrangle by using geometrical features which are extracted from the approximated line segments. It normalizes the shape of extracted quadrangle into exact squares by using the warping technique and scale transformation. It extracts feature vectors from the square image by using principal component analysis. It then checks if the square image is a marker image or a non-marker image by using a SVM classifier. After that, it computes feature vectors by using LDA for the extracted marker images. And it calculates the distance between feature vector of input marker image and those of standard markers. Finally, it recognizes the marker by using minimum distance method. Experimental results show that the proposed method achieves enhancement of recognition rate with smaller feature vectors by using LDA and it can decrease false detection errors by using SVM.

Cardiopulmonary resuscitation (CPR) is a series of life-saving actions that improve the chances of survival, following cardiac arrest. Successful resuscitation, following cardiac arrest, requires an integrated set of coordinated actions represented by the links in the Chain of Survival. The links include the following: immediate recognition of cardiac arrest and activation of the emergency response system, early CPR with an emphasis on chest compressions, rapid defibrillation, effective advanced life support, and integrated post-cardiac arrest care. The newest development in the CPR guideline is a change in the basic life support sequence of steps from "A-B-C" (Airway, Breathing, Chest compressions) to "C-A-B" (Chest compressions, Airway, Breathing) for adults. Also, "Hands-Only (compression only) CPR" is emphasized for the untrained lay rescuer. On the basis of the strength of the available evidence, there was unanimous support for continuous emphasis on high-quality CPR with compressions of adequate rate and depth, which allows for complete chest recoil, minimizing interruptions in chest compressions and avoiding excessive ventilation. High-quality CPR is the cornerstone of a system of care that can optimize outcomes beyond return of spontaneous circulation (ROSC). There is an increased emphasis on physiologic monitoring to optimize CPR quality, and to detect ROSC. A comprehensive, structured, integrated, multidisciplinary system of care should be implemented in a consistent manner for the treatment of post-cardiac arrest care patients. The return to a prior quality and functional state of health is the ultimate goal of a resuscitation system of care.

Automatic Video Surveillance System (AVSS) has become important to computer vision researchers as crime has increased in the twenty-first century. As a new branch of AVSS, baggage detection has a wide area of security applications. Some of them are, detecting baggage in baggage restricted super shop, detecting unclaimed baggage in public space etc. However, in this paper, a detection & classification framework of baggage is proposed. Initially, background subtraction is performed instead of sliding window approach to speed up the system and HSI model is used to deal with different illumination conditions. Then, a model is introduced to overcome shadow effect. Then, occlusion of objects is detected using proposed mirroring algorithm to track individual objects. Extraction of rotational signal descriptor (SP-RSD-HOG) with support plane from Region of Interest (ROI) add rotation invariance nature in HOG. Finally, dynamic human body parameter setting approach enables the system to detect & classify single or multiple pieces of carried baggage even if some portions of human are absent. In baggage detection, a strong classifier is generated by boosting similarity measure based multi layer Support Vector Machine (SVM)s into HOG based SVM. This boosting technique has been used to deal with various texture patterns of baggage. Experimental results have discovered the system satisfactorily accurate and faster comparative to other alternatives.

The purpose of this study is to investigate teachers' recognition and to suggest an improvement in the system of teacher's observation and nomination used to selecting gifted and talented students in Science in the Busan Metropolitan School District in 2013 by investigating teachers' recognition of the system and their expressed needs. The results are as follows. First, it was observed that teachers are of the opinion that it is difficult to determine the science gifted students by observation due to their lack of expertise in giftedness and gifted education, the lack of a check list to use, and the difficulty of ensuring the objectivity of the results of the determination. Second, the absence of objective screening tools used for the selection, the selection of gifted students based on their subjective judgment, and the possibility to select students based only on visible manifestations of ability may cause parents to mistrust the system. Thus, institutional support is required to address the concerns of teachers and parents. Third, the teachers who are in charge of observation, nomination, selection and determination need to be trained. After that, at least one of these teachers should be assigned in each school and training should operate continuously and systematically. Lastly, while these things are occurring, the process of observation and nomination of by teachers, which is the basis of pooling gifted students at the level of Busan Metropolitan School District, should be continued.
