안효창 한국기독교교육정보학회 2003 기독교교육정보 Vol.6 No.-
The purpose of this study is to analyze the "Curriculum for Holy Life and to suggest improvements for theologizing its education for holiness. Theologization of education is to picture Christian education system and to embody its component. And it also seeks theological meanings to Christian educational performance. The main task in the theologization of education for holiness is to study the curriculum for holy life in order to see which parts contribute to holiness as the goal and process of education. The study, therefore, emphasized three points. First, the theological meaning of holiness was explored based on the origin of holiness, the biblical meaning of holiness, and the theological definition of holiness. Second, sin, repentance, and holiness were used as three structural elements for conceptualizing the theologization of holiness education. Third, the study suggested educational goals, curricular organization of educational contents, and instructional methodology. Research for the theologization initially used the following three theologies. Wesley, Calvin, and Pentacost. Wesley was then selected as the theologian with the highest validity. The result was the theologization of holiness education on the basis of Wesley's theology, Sin, repentance, and holiness were defined as three elements of theologization of holiness education. The study then analyzed the "Curriculum for Holy Life" --its educational goals, content, and methodology on the basis of three elements of the theologization of holiness education. The three elements were also examined in analyzing the instructional methodology. The main findings of the study are as follows. First, theory and practice are not in harmony in the educational theology of the Korea Evangelical Holiness Church's curriculum entitled, "Holiness life." Second, by recognizing a radical aspect and a gradual aspect of holiness in the process of conceptualizing the theology of education, Wesley's theology was discovered to be the most appropriate for representing the gradual aspect. Third, after the structural elements of sin, repentance, and holiness were defined, It was discovered that when sin was put into the designed theologization model, it produced holiness through the process of repentsnce. Fourth, it was discerned that teacher-oriented educational styles and praxis-centered methods were preferred to theory-centered methods as the instructional methods. Finally, it was recognized that the educational curriculum has to be improved to achieve holiness through shared praxis methods, and that Thomas H Groome's shared Christian praxis approach is appropriate for the theologization of education for holiness The following recommendations are suggested for the development and study of theologization of education for holiness First, an innovative educational curriculum should be designed and theologized for holiness education. Second, the linking of theological structure and educational methodology is essential for renewing the educational curriculum based on the theologization of education in the Korea Evangelical Holiness Church. Third, educational curriculum and materials, whereby pedagogical structure and process for holiness are encountered, should be developed. Finally, this study will provide an impetus whereby theology, holiness, and education can be realistically combined.

RFID는 정보통신 외에 물류, 유통, 교통, 환경 등 다양한 분야에 적용될 수 있기에 유비쿼터스 시대에 없어서는 안 되는 기술로 각광받고 있다. 하지만 최근들어 RFID 보안의 무제가 거론되고 있어서 RFID의 정보보가 필요하게 되었다. 본 논문에서는 RFID 태그에 얼굴 생체 특징 정보를 효율적으로 저장하여 인증성을 보장하고 개인의 정보를 보호할 수 있는 알고리즘을 제안한다. 데이터양이 많은 생체 특징 정보를 개선된 선형판별 분석방법을 이용하여 특징 정보 차원을 감소시킴으로써 데이터양을 효과적으로 줄여 RFID 태그의 적은 메모리 영역내에 특징 정보를 저장하였다. 실험결과 사용자 인증율이 92%를 보였으며, 출입통제 시스템 및 전자 신분증 등에 활용 가능한 시스템으로 적용 가능할 것으로 보인다. RFID could be applied in the various fields such as distribution beside, circulation, traffic and environment on information communication outside. So this can speak as point of ubiquitous computing's next generation technology. However, it is discussed problem of RFID security recently, so we must prepare thoroughly about RFID security for secure information. In this paper, we proposed a method which could protect private information and ensure RFID's identification effectively storing face feature information on RFID tag. Our method which is improved linear discriminant analysis has reduced dimension of feature information which has large size of data. Therefore, we can sore face feature information in small memory field of RFID tag. Our propose d algorithm has shown 92% recognition rate in experimental results and can be applied to entrance control management system, digital identification card and others.

가루해백반하탕 추출물이 배양 심근세포의 박동수와 LDH 활성도에 미치는 영향

To certify the protective effect of herbal medicine against oxygen free radical-induced myocardiotoxicity, cytotoxicity was measured using MTT, LDH activity and Beating rate assay in the presence of Guaruhaebaekbanhatang(GHBT) extracts or single constituents of this prescription. Myocardial toxicity was evaluated in neonatal rat myocardiocytes in cultures. In the present study, xanthine oxidase/hypoxanthine(XO/HX) resulted in a decrease in cell viability, increases in LDH activity in culture medium and decreases in beating rate in cultured myocardial cells. In the effect of GHBT extract, it showed the prevention from the XO/HX - induced cardiotoxicity by the increases of cell viability and beating rate as well as the decrease of LDH activity. In the protective effect of Fructus Trichosanthis (FT), Bulbus Allii Macrostemi(BAM) and Rhizoma Pinelliae(RP), all the extracts were significantly effective in the protection of XO/HX-induced cardiotoxocity in cultured myocardial cells by the increase of beating rate as well as the decrease of LDH activity. From these results, they show that XO/HX is cardiotoxic in cultured myocardial cells derived from neonatal rat, and it suggests that GHBT, FT, BAM, RP extracts are positively effective in the blocking in XO/HX-induced cardiotoxicity.

단일 영상에서 안개 제거 방법을 이용한 객체 검출 알고리즘 개선

In recent years, with the development of automobile technology, smart system technology that assists safe driving has been developed. A camera is installed on the front and rear of the vehicle as well as on the left and right sides to detect and warn of collision risks and hazards. Beyond the technology of simple black-box recording via cameras, we are developing intelligent systems that combine various computer vision technologies. However, most related studies have been developed to optimize performance in laboratory-like environments that do not take environmental factors such as weather into account. In this paper, we propose a method to detect object by restoring visibility in image with degraded image due to weather factors such as fog. First, the image quality degradation such as fog is detected in a single image, and the image quality is improved by restoring using an intermediate value filter. Then, we used an adaptive feature extraction method that removes unnecessary elements such as noise from the improved image and uses it to recognize objects with only the necessary features. In the proposed method, it is shown that more feature points are extracted than the feature points of the region of interest in the improved image.
