Computed tomography (CT) is one of the most widely used medical imaging modality. However, substantial x-ray dose exposed to the human subject during the CT scan is a great concern. Region-of-interest (ROI) CT is considered to be a possible solution for its potential to reduce the x-ray dose to the human subject. In most of ROI-CT scans, the ROI is set to a circular shape whose diameter is often considerably smaller than the full field-of-view (FOV). However, an arbitrarily shaped ROI is very desirable to reduce the x-ray dose more than the circularly shaped ROI can do. We propose a new method to make a non-circular convex-shaped ROI along with the image reconstruction method. To make a ROI with an arbitrary convex shape, dynamic collimations are necessary to minimize the x-ray dose at each angle of view. In addition to the dynamic collimation, we get the ROI projection data with slightly lower sampling rate in the view direction to further reduce the x-ray dose. We reconstruct images from the ROI projection data in the compressed sensing (CS) framework assisted by the exterior projection data acquired from the pilot scan to set the ROI. To validate the proposed method, we used the experimental micro-CT projection data after truncating them to simulate the dynamic collimation. The reconstructed ROI images showed little errors as compared to the images reconstructed from the full-FOV scan data as well as little artifacts inside the ROI. We expect the proposed method can significantly reduce the x-ray dose in CT scans if the dynamic collimation is realized in real CT machines.

This study is to analyze the concentration of visual perception of the subject through the eye-tracking experiments targeting popular characters and to investigate it is effective to highlight which part of the character in inducing consumers' interest and curiosity. As a result of the study, the subjects paid more attention to the face than the character's body, and also noted a little attention to auxiliary elements such as pants, tees, shoes, and whiskers. These results mean there is clearly different factor in which the subject's gaze on the character frequently stays and does for a long time. Therefore, the designers should recognize the differences of the concentration of visual perception by character components as a differentiating factor to feel the emotional satisfaction such as the user's interest, empathy, and immersion in the character and actively reflect it when developing the character design. In addition, there was a difference in the visual perception concentration of each of the auxiliary elements, and if careful research is done on whether the influence factors are also due to individual characteristics or another influential factors, it will be a wider study on character design.

Korea is a record powerhouse nation with the largest number of Memory of the World in the Asia-Pacific; however, active utilization of archives for future generations has been lacking. Therefore, this study sought to enhance interest in archives and utilize them directly in school lessons. The Korean National Debt Redemption Movement's archives, which were selected as a Memory of the World, were used in the school lessons, and based on them, a library collaborative instruction design was developed. A library collaborative instruction is a collaboration between the high school Korean history subject and the library information literacy instruction, designed in three sessions. Through the literature research-based design, a library collaborative instruction plan, teaching and learning plan, and activity sheets were derived. Implementing this designed library collaborative instruction is expected to stimulate interest in the Memory of the World, linking curriculum and archives at schools and significantly expanding the users of the archives into teachers and students.

The aim of this study is to research and analyse how junior-high students, both male and female in Inchon area, are recognizing the contents of the curriculum in the subject of home economics and how effectively they are learning and applying it in their actual life. 772 students, both male and female, who started to learn the subject of home economics from the 7th grade as compulsory are the respondents, and the survey is done by using questionnaire. The result shows that after taking the course of home economics, both male and female students have got more positive view on the necessity of learning the subject. But still, on the whole, female students are more intersted and more active than males the subject in learning. As for food and nutrition part, large percentage of the respondents, both male and female, answer that it is very helpful. They tend to be on more balanced diet and when they purchase food or when they eat at restaurant they refer what they learn about nutrition at school more often than not. A number of the students are re-practicing cooking at home after they learn it at school. Also the fact in the survey shows that more and more mothers are getting active in asking their children to re-practice cooking. One of the difficulties for male students to take the course is stereo-typed thinking on the separate role of man and woman in the family. But many of them started cooking some food, even though it is very simple, and the survey shows that their interest in nutrition and health increased after they were initiated into this course.

As the environmental problems are recognized as daily problems in our lives, not as issues of those who are engaged in specific professional fields, the interest in environmental education is increasing gradually. The environmental education is the one that studies the environment and its problems and seeks the solutions for them. This paper deals with how the Korean subject will include environmental education. The environmental problems are already dealt with in the Korean textbooks according to the 6th curriculum for the Korean subject. A noticeable fact is that those textbooks connect the skills for language skills with environmental education. That is, the textbooks try to improve 4 language skills (speaking, listening, reading, and writing) with the Korean data related to environment, which can be the most practical means. This tendency will be also reflected in the 7th curriculum for the Korean subject, and the means will be taken by which environmental education will be able to be implemented more effectively through a variety of learning activities. In case of speaking and listening, learning activities such as speaking of, listening to, or discussing the contents concerning environmental problems can be recommended. In case of reading and literature, learning activities such as reading articles or works concerning environmental problems. Through these learning activities the Korean education will be able to achieve the goal in the fields of knowledge, information, and autonomy or attitudes which are the goals of environmental education. If the contents of the Korean curriculum are described in detail, it can be known that the Korean subject have someting to do with knowledge, skills, and recognition more deeply. In the methods In obtain information and knowledge, it will be desirable to recognize knowledge and information indirectly through various reading data rather than to recognize knowledge and information directly. Or it will be desirable to increase the sensitivity about environmental problems through literary works. For this environmental education in the above, we need to utilize discussion or presentation-oriented leaching and learning in the Korean education. Also we need to approach environmental problems by using various teaching media. We need to emphasize the education in the affective domain, especially through expression of emotions. guidance of reactions, internalization, personification, and so on.

The purpose of this study was to research middle school students' interest and practice about the housing education contents in Technology and Home Economics Subject(classify them into three units, application of living space, indoor environment and equipments. support and repair of housing) in their real life. This was the investigation of which 529 middle school students have lived in Jeonbuk province, SPSS program was utilized to analyze percentage. mean and standard deviation. as well as t-test, One-Way ANOVA and Pearson's correlation coefficients. The results of this research were as follows: Middle school students' interest and practice of the housing education contents appeared to the middle level. Middle school students was consider that the order of interest parts of housing contents were indoor environment and equipments. application of living space, support and repair of housing. And the order of practice parts of housing contents were application of living space. indoor environment and equipments. support and repair of housing. There were significant differences in interest and practice of contents according to demographic variables such as sex, educational level of parents, social status of home. school record. Interest about the housing education contents had significant positive relationships with practices of contents of housing education. Therefore. it would be necessary to develop teaching materials and housing education contents promoting interest of students.

This study was practiced to compare educational status and recognition of Home Economics curriculum between alternative and general middle school students. The survey was conducted to 130 alternative school students and 241 general school students in Gyeonggi province. In students' satisfaction on their school, there is appeared the highest at 'average'(38.6%) in general schools and 'satisfied'(40.8%) in alternative schools, showing that those in alternative schools have greater satisfaction on their schools(p<0.001). In the degree of recognition on Home Economics curriculum, the perception as an 'important subject' was average of 3.08/5 points in general school and 3.32/5 points in alternative school, indicating that the recognition in alternative schools was higher than general ones(p<0.05). Also, degree of satisfaction on practice and lecture class was higher in alternative than general schools. However, it was found that the use of audiovisual learning material in alternative schools was much smaller than that of general ones, and the former had poor facilities and practice labs. Regarding degrees of interest in Home Economics curriculum, 'average'(36.9%) in general school and 'rather interested in the subject'(38.5%) in alternative schools were most common. About the opinion that they needed to learn Home Economics subject, the answer 'it is needed' was 67.6% in general schools and 79.2% in alternative ones, presenting that the students in alternative schools more felt the need to learn the subject(p<0.05). Regarding the comparison of interest level for each area in Home Economics curriculum according to gender, there was only difference on the area of 'preparation and management for clothing'. On the area, the degree of interest was higher in girls than boys at all the schools(p<0.05). Therefore, in alternative schools, it is suggested that various uses of audiovisual learning materials at teaching and expansion of practice facilities should be provided and created desirable Home Economics class. Also in general schools, it is urgent that countermeasures to increase the practice classes are established in order to improve interest and satisfaction of Home Economics education.

Mathematics is the subject that requires high mental function such as the ability of logically thinking and investigating. Because of the reason there exists much greater difference in students' individual scholastic abilities in mathematics class than in other classes. Recently many schools organize students into two or three level-based mathematics classes according to each student's level to solve the problem. But in spite of its many merits the new system of class organization has some problems. The problem which is pointed out as the most serious thing frequently is that many teachers still use the same textbook and the same teaching method for all students, not considering student's level. Obviously it causes the reduction of students' interest and motivation. In this point of view, I tried to solve such a problem by development and application of level learning materials reconstructed text book according to students' abilities and levels through this research. As the result of the research to examine the changes of students' emotional factors such as the recognition, interest, and attitude which influence on improving self-educability in learning mathematics has occurred, the following conclusion comes out. 1. Through the mathematics class utilizing level learning materials reconstructed textbook, students come to recognize that level learning materials are more effective than uniformed contents of the same textbook and get more active learning attitude. 2 The application of level learning materials in a level-based class has contributed to increasing students' interest in mathematics. Furthermore it was also effective in the positive changes of students' emotional factors such as the recognition, interest, and attitude which influence on improving self-educability in learning mathematics.

This Study is divided into 5 separate Parts and an Abstract. Part Ⅰ, Ⅱ consist mostly of a collection of problems, current status, motives and the future of ADR. In Pert Ⅲ was described ADR as policies of judicial settlements. We must accept that a diversity of legal culture will always continue to exist. Accordingly we must learn to accommodate those differences of 'culture' around us and to harmonize conflicting laws. This recognition of our reality should in no way be confused with pessimism. In fact if one accepts this perspective of the world ,the study of law seems enriched and becomes academically more challenging. Recently, in the United States, interest in alternative settlement mechanism has increased greatly, which leads me to wonder why such a phenomenon has taken place. In the first place, I'm amazed at the extent to which conciliation or mediation-or the new word, I guess, is alternative dispute resolution, which by now has its own acronym, "A.D.R,"-have gained attention here recently. When 35 years ago, there was virtually no interest in conciliation in this country at the time. What interest there was, was no in the law schools. But looking at the situation now, we have a spate of publications on the subject; we have organizations that are established for no other reason than to promote alternative dispute settlement. We have courses in the law schools. The American Association of Law Schools and the American Bar Association also have active programs. So we have to ask ourselves why. The difference between now and 35 years are striking. On the other hand, I think the interest of the public in ADR has probably been greatly enhanced by the politics of the so-called "poverty programs." I think that many of these assistance programs for the poor-and I do think the "poor" have become a rather expansive political movement beyond simply taking care of the most marginal people of society-have generated money to explore this kind of dispute resolution.

As the influence of SW spreads, many countries concentrate on SW education policies for women. Although the SW education is strengthened, study on the curriculum suitable for women is still insufficient. The study conducted 422 middle school students to investigate differences in perception of SW by gender. It consisted of 207 male students and 215 female students, and survey analyzed in three categories : SW environment, SW education awareness and SW career interest. The analysis showed that SW education for female students is necessary to increase the confidence and interest in them, and that SW education opportunities for female students should be expanded so that interest and expectation of information education should be increased. In addition, it is necessary to introduce and promote SW related career path which can increase interest in SW related job and SW related major. This study is meaningful in that at this point when the revised curriculum begins to be applied, there are differences in perception of informatics and SW by gender, and that it is necessary to study the SW curriculum suitable for gender for effective achievement.
