PURPOSES: This study is to develop a road traffic sign recognition and automatic positioning for road facility management. METHODS: In this study, we installed the GPS, IMU, DMI, camera, laser sensor on the van and surveyed the car position, fore-sight image, point cloud of traffic signs. To insert automatic position of traffic sign, the automatic traffic sign recognition S/W developed and it can log the traffic sign type and approximate position, this study suggests a methodology to transform the laser point-cloud to the map coordinate system with the 3D axis rotation algorithm. RESULTS: Result show that on a clear day, traffic sign recognition ratio is 92.98%, and on cloudy day recognition ratio is 80.58%. To insert exact traffic sign position. This study examined the point difference with the road surveying results. The result RMSE is 0.227m and average is 1.51m which is the GPS positioning error. Including these error we can insert the traffic sign position within 1.51m CONCLUSIONS: As a result of this study, we can automatically survey the traffic sign type, position data of the traffic sign position error and analysis the road safety, speed limit consistency, which can be used in traffic sign DB.

목적: 본 연구는 초등학교 담임교사를 대상으로 시각에 대한 인식 현황을 파악하여 초등학생의 시각에 대한 교사들의 관심과 적절한 지도를 제안하고자 한다. 방법: 2011년 4~7월까지 경기도 화성시 O초등학교 담임교사 112명을 대상으로 설문조사를 실시하였다. 불성실하게 응답한 12부를 제외한 100명의 자료를 분석하였다. 결과: 시각 문제를 담당하기 적합한 전문가는 안과의사라고 인식하고 있는 교사가 88%였다. 학생에게 전문기관에서 눈 검사를 받도록 권유해본 적이 있었던 교사는 76%였다. 현행 교육과정에 시각에 대한 교육 내용이 포함되어 있다고 인식하는 교사는 24%였고 시각에 대한 내용이 교육과정에 필요하다고 인식하는 교 사는 80%였다. 시각이상이라는 용어를 인식하는 교사는 71%, 저시력이라는 용어를 인식하는 교사는 54%, 시각치료라는 용어를 인식하는 교사는 22%였다. 시각이상의 존재여부를 증상으로 알 수 있다고 생각하는 교사는 22%였다. 선호하는 시각관련 정보 제공 형태는 46%가 웹싸이트를 선호하여 가장 높은 선호도를 보였다. 결론: 초등학교 교사들이 시각에 대한 정보가 부족하고 시각에 대한 인식이 낮으므로 초등학교 교사를 대상으로 하는 시각 교육이 이루어져야 할 것으로 보인다.

In most child-care facilities, homeroom teachers take the responsibilities for safety education, which has been conducted in class hours on a regular basis. It was found that most homeroom teachers are lacking in teacher training opportunities, and the younger they are, the less training experience they get. Teachers with fewer teaching careers had a greater interest in safety education and training courses. In addition, homeroom teachers have been utilizing monthly toddler magazines as a method to acquire knowledges for safety education and prevention of safety accidents. The safety accidents which have most frequently occurred in care-care facilities turned out to be stumble and tear, and infants aged 3 years or younger were found to be easily exposed to the safety accidents mainly due to the frolic between peers during the free-choice activity time. The homeroom teachers recognized only traffic safety education among the range of safety training courses, which varied depending on teaching career such as traffic safety education and indoor/outdoor safety environment training, etc. In addition, it turned out that the safety training methods were limited to the utilization of discussion techniques, role-playing, description and demonstration.

This study compared data regarding industrial accidents and awareness level for beauty product safety for four main parts of beauty industry such as hair-care, nail-care, skin-care, and make-up. Major risk factors in beauty industry are dust, musculoskeletal disorders, and organic solvent of beauty product in order of percentage. The specific types of industrial accidents in beauty industry are mainly associated with musculoskeletal system such as cuts, sprain, and varicose vein. They are mainly compensated by personal budget. The awareness levels of chemical and heavy metal containment for beauty product by beauty industry employee were 77.2% and 59.1% respectively. Most employee confirmed only important items of labelling requirement of beauty product. Also, most employee did not understand MSDS(Materila Safety Data) for chemicals used in beauty industry. Only 38.1% of beauty industry employee has had safety education while most employee (73.6%) realized that they needed safety education. Also, safety education supervised by KOSHA(Korea Occupational Safety and Health Agency) was the most preferred. This study would be good basis for safe and healthy working environment of beauty industry employee.

he purpose of this study is to offer youth with the basic materials for developing nutrition education programs and to help domestic science teachers in schools implement effective dietary education by examining their awareness of food additives. In the source of acquiring knowledges on food additives, the results were through mass media, technology and home economics teachers, and family members in order. The majority of students thought that they don't need the education about food additives. As effective teaching methods, they first selected the use of visual media, followed by experimental cooking classes, field trip, and inquiry lessons using processed foods. As a result of analyzing the education on food additives in accordance with demographic factors, more number of female students, compared to male students depicted the need for education on food additives. Further, the lower the cost students spend on purchasing processed foods per day, the higher the necessity of the education they indicate. The necessity of education content on food additives showed significant difference depending on the cost of buying processed foods, and the degree of interest and help real-life according to gender indicated significant differences. The satisfaction with education on food additives, which was implemented in home economics education revealed significant differences according to gender. This study aims to provide the basic data for the development and research of educational programs regarding good eating habits among the general youth. However, there are limitations to the presentation of the practical training program. For this reason, based on the results of this study, further studies should follow this study in order to develop and study educational programs related to food additives for teaching and learning purposes.

This study was conducted to investigate the differences in households, parental perception, and dietary behaviors of preschool children from kindergartens with environment-friendly food service (environment-friendly food service group; EFG) versus children from kindergartens with general food service (general food service group; GFG). We sought this basic information to examine the impact of environment-friendly agricultural products in preschool food services. Age, education level, and monthly family income of the EFG were significantly higher than the GFG. The frequency of purchasing environment-friendly agricultural products was significantly higher in the EFG than the GFG, with the most frequently purchased items in both groups being vegetables. The GFG had a significantly higher perception than the EFG in the superior quality of environment-friendly agricultural products; however, a greater proportion of the GFG than the EFG thought environment-friendly products were too expensive. The most frequent reason for purchasing environment-friendly agricultural products in both groups was safety. When purchasing environment-friendly agricultural products, the most important selection factor for the majority of both groups was the label certifying quality assurance. Both groups also considered price reduction as essential for promoting environment-friendly agricultural products. In regard to parental perceptions on food service in kindergarten, the EFG had a significantly higher satisfaction with the nutritional adequacy of the menu compared to the GFG. Both groups considered food safety and health as primary reasons for using environment-friendly foods in the preschool food service, with a greater proportion of the EFG than the GFG responding this way. There were significant differences between the EFG and GFG, as the main satisfaction from using environment-friendly foods in the EFG was safety, freshness, and good hygiene, whereas the main satisfaction in the GFG was a good food service menu, freshness and good hygiene. Dietary behaviors of preschool children in the EFG were also significantly superior to the GFG. Thus, environment-friendly agricultural products have positive effects on the dietary behaviors of preschool children and should be increased in the preschool food service. Lowering prices and a strict supervision of quality assurance is also necessary to promote consumption of environment-friendly food materials.

In this article I studied the novels and essays of Park Hwa-Seong, who was a representative woman in the 1920-30s as a tendency writer. She wrote a lot of novels over 60 years from 1925 when she became a writer till 1988 when she died. The literary world of Park Hwa-Seong changed greatly according to the conditions of times. In this article, above all, I want to focus on her novels that dealt with the christianity as a subject matter in order to prove the characteristics of recognition of christianity expressed in her works. This study can be an example of how the tendency writers of the 1920-30s recognized christianity and expressed their ideology in their work. Park Hwa-Seong had a specific biography in respect of christianity as a tendency writer in the 1920-30s. She was baptized as an infant and led a religious life very eagerly in her youth. However, as she became a tendency writer and wrote realistic novels reflecting the conditions of the bard times, Japanese colonial era, she wrote novels which expressed negative recognition of American missionary and protest providence of God. In the 1920s-30s, the tendency writers looked upon christianity as a certain ideology for tbe perspective of socialism and criticized it on the ground that christianity could not improve the conditions of colonial reality. As an intelligent leader, she considered anti-christian emotions as an act of nationalistic faith to overcome Japanese colonial conditions. So the reason why she wrote negative christian view in her novels in the 1930s was to disclose the feeling of helplessness of christianity which couldn't revolutionize the dismal reality of nation. For examnple, the short story "Hangui" showed the question of theodicy, why the good had to suffer from hunger and poverty despite the prosperity of the evil. She doubted about the presence of God and became a skeptic of God in her life. Nevertheless she didn't leave the christianity and lived a christian life in a specific method. If she had not known the christianity，she could not have written such a novel that raised a metaphysical question about the providence of God. Through her life, Park Hwa-Seong created works differently according to the times. But as she was a writer who had related with christian background from her childhood，in the time of Japanese colonial period, she used christianity as subject matters in her works. AIso she showed christian consciousness in the form of negative as a tendency writer and expressed writer's recognition of chrisrianity as a skeptic of God honestly in the latter part of her literary world.

본 연구는 시대적인 흐름에 따른 경관인식 변화를 살펴보기 위하여 과거 신문에 나타난 관련 기사를 분석하였다. 연구방법으로는 네이버 뉴스라이브러리에서 제공하는 1920년대부터 1999년까지의 동아일보, 경향신문, 매일경제, 한겨레신문 등의 기사를 연구 대상으로 경관관련 기사를 검색하였으며 이를 시대별로 흐름을 살펴보는 방식을 취하였다.1920년부터 1945년까지 경관이라는 용어는 주로 아름다운 자연경치라는 의미로 주로 사용되었으며 당시 동경의대상이었던 외국의 근대적인 도시 모습을 지칭하는 개념으로도 사용되었다. 1946년부터 1960년까지는 독립과 한국전쟁을경험한 시기로 국가재건과 같은 이슈에 비해 상대적으로 경관에 대한 사회적 관심이 떨어졌던 시기였다. 1960년대에는새로운 국토건설과 관리의 필요성이 대두되어 성장하는 도시, 국토의 발전 등의 의미로 경관에 대한 인식이 확대되었으며 동시에 개발에 따른 자연 훼손을 우려하는 의미로도 사용되었다. 1970년대에는 고속도로건설과 새마을운동이라는 개발위주의 정책과 함께 다양한 대상에 대한 경관관리의 필요성이 대두되었다. 1980년대에는 아시안게임과 서울올림픽준비로 대대적인 경관정비가 진행되어 이를 계기로 경관관련 계획과 제도의 기틀을 마련하였다. 1990년대에는 경제수준향상으로 각종 경관관련 제도가 본격적인 틀을 갖추기 시작하였다. 경관심의가 강화되고 각종 경관계획이 수립되었다.

This paper presents a new feature representation method, named two- dimensional orthogonalized Fisher discriminant analysis(2D-OFD). The method adopts the 2D-LDA and orthogonalization of Fisher vector. It produces the small size scatter matrix than 1D method. Therefore it can evaluate the scatter matrix accurately. In addition, it is not suffered from small sample size problem. The orthogonalization eliminates the linear dependences among Fisher's discriminant vectors. As a result, it promotes the discriminant capability of the 2D-LDA. The proposed method is tested on the ORL face image database. We test our method 10 times. For each experiment, five training images are randomly chosen each person and the other five images are used for testing. The test show that the average recognition rate is 96.2%. When the image is downsampled to 28x23 matrix to reduce the computational complexity, the average recognition rate is 95.9%.
