The purposes of this study are 1) to identify the position and the problems of Home Economics in Elementary School, and 2) to propose orientation for the future curriculum revision. Elementary Home Economics, historically, has been partially practiced as a part of Practical Arts Education. As a results, the nature of Home Economics Education has been distorted and lacked the disciplinary consistency with Middle School Home Economics Education： the curriculum of Home Economics Education ignored the importance of the understanding family life as well as underscored the technical skills. The identified status and problems has on implication for the subject’s further development. The propositions for Elementary Home Economics Education which has the original intention, are as follows：(1) the curriculum of Practical Arts Education must be built on theorectical base and criteria. (2) the name of subject, Practical Arts Education, must be changed to [Technology$.$Home Economics]. (3) the contents of the subject must be practical which to promote motivations and interest of students.

Mathematics becomes more indispensible course today, while it seems approaching to the middle school students as a boring and hard one. So, we need to take more motivational teaching devices as well as mere emphases on its importance in order to keep the students up to tile curriculum and improve the education efficiency. Then, history of mathematics call lie one major source of the motivation, since, by telling the tales on the specific unit subject, teachers can awake the students'interest naturally. Today, most of the mathematics textbooks for the middle school students have some historical tales about each unit subject in their respective unit introduction. However, many tales don't seem quite helpful or motivating to understand unit subjects, for they are either abstract or fragmental. In that sense, this paper has three sample guidelines for teaching, which ate meant to introduce historical tales to motivate the students before teachers may get into tile main unit subject. Those suggested in this paper may work as the motivational teaching devices which would make the students mote interested, more positive, and consequently more successful in mathematics.

This study attempted to compare the social interest, motivation, and attitude of nursing college students who participated in a voluntary program and the students who didn't participate in a voluntary program. The purpose of this study can be summarized as to find the effect of a voluntary program and to offer fundamental data for institutionalizing a voluntary program in college. The subjects were composed of two groups, one group attend the voluntary program and the other group doesn't. The subjects were 390 nursing students: 179 in the experimental group and 211 in the control group. The results of this study are as follows : 1. Before voluntary activities, the mean value of the control group was higher than that of the experimental group in social interest and altruistic motivation. The difference is statistically meaningful(t= -2.2.53, p=.25, t= -2.509, p= .013). 2. After voluntary activities, selfish motivation and altruistic motivation in the experimental group was higher than before. The difference is statistically meaningful(t= 2.404, p=.0l7, t=-2.751, p=.007). 3. The social interest, selfish motivation, altruistic motivation toward voluntary activities and selfish attitude, altruistic attitude toward voluntary activities will not have changed in the control group before or after voluntary program. However, the altruistic attitude lowered after voluntary activity. It is statistically meaningful(t=2.694, p=.008). 4. After the voluntary activities, there was a significant difference between the experimental and control groups in altruistic attitude. In the experimental group, the mean value of altruistic attitude increased significantly, but in the control group the mean value of altruistic attitude decreased ( t = 2.15, p = .032). The results of this study showed that voluntary activities not only increase social interest and altruistic attitude, but also the subject's understanding toward the community. 3.

The purpose of this study is to increase students' interest in the subject of English, which has been led by some mannerism, and to improve the students' basic scholastic ability and self-controlled problem solving, through adopting an individualized Web Based Instruction(WBI) as a concrete and practical learning method. In order to achieve this, an individualized Web Based Instruction(WBI) homepage has been developed to be applied experimentally to the field of middle school education for 8 months, and a research has been made on its effects on the students' interest in English along with the improvement of English. Two groups which showed almost the same interest were selected as a controlled group and an experimental one. Individualized Web Based Instruction was applied to the experimental group, while the controlled group was not instructed according to student ability. The controlled group was taught using CD added with the textbook. As a result of T-test, the students in the experimental group showed more improvement in communicative competence than those in the controlled group.

In ultrasonic bone densitometry, the positioning of measurement site is decisive in precision and reproducibility. In this study, automatic Region of Interest (ROI) detection algorithm is suggested and adopted the method using the local minimum value by ultrasonic image. The preprocess before the local minimum method extracts out the bone area and calculates the geometrical information of bone. The developed ROI detection algorithm was applied to the clinical test for the subject of 305 female patients in the range of 22-88 years old. As the results, the accuracy of the algorithm was shown to be 98.3％. It was also found that bone density parameter was significantly correlated with age(r=0.85, p<0.0001).

최근 모바일 서비스에서 콘텐트를 요약 정보가 담긴 리스트 형태로 제공하는 경우가 증가하고 있다. 이에 따라 사용자가 콘텐트에 관심이 있어도 별점이나 클릭과 같은 명시적 혹은 암묵적 관심을 표현하지 않고 요약 정보를 통해 콘텐트를 소비하는 잠재 관심 표현이 대다수를 차지하게 되었다. 따라서 사용자의 관심을 파악하기 위해서는 잠재 관심 콘텐트의 추론이 필수적이다. 본 연구에서는 사용자의 모바일 상의 콘텐트 소비 로그 패턴을 분석하여 잠재 관심 콘텐트를 추론하는 기법을 제안한다. 특히, 실제 서비스에 적용 시 잘못된 관심 추론은 치명적일 수 있다는 점에서 추론의 정밀도를 극대화시키기 위해 서로 다른 특성을 반영한 다수의 분류기가 모두 동의한 경우에 잠재 관심 콘텐트로 추론하는 만장일치 앙상블 방식을 도입한다. 자체 제작한 어플리케이션으로부터 콘텐트 소비 로그를 수집하였으며 이를 이용하여 제안 방법론의 우수한 성능을 확인하였다. 이러한 잠재 관심 아이템의 정확한 도출은 사용자의 관심에 기초한 추천 시스템과 같은 개인화 서비스의 질 향상에 기여할 것이다.

We introduce a rotating-gantry-based x-ray micro-tomography system to be used for small animal imaging studies. It has the zoom-in imaging capability for high resolution imaging of a local region inside the animal subject without any contrast anomalies arising from truncation of the projection data. With the sliding mechanism mounted on the rotating gantry holding the x-ray source and the x-ray detector, we can control the magnification ratio of the x-ray projection data. By combining the projection data from the large field of view (FOV) scan of the whole animal subject and the projection data from the small FOV scan of the region of interest, we can obtain artifact-free zoomed-in images of the region of interest. For the acquisition of x-ray projection data, we use a $1248{\times}1248$ flat-panel x-ray detector with the pixel pitch of 100 mm. It has been experimentally found that the developed system has the spatial resolution of up to 121p/mm when the highest magnification ratio of 5:1 is applied to the zoom-in imaging. We present some in vivo rat femur images to demonstrate utility of the developed system for small animal imaging.
