To find out the effect of interest on chemical content, interest in chemistry, choice of science elective subjects, teaching-learning characteristics that make it difficult to understand contents, academic achievement in general chemistry according to university admission screening, etc. were surveyed on 51 students enrolled in the department of chemistry education at P college of education. As a result of the survey, it was found that the interest in Chemistry I, Chemistry II, and general chemistry increased significantly to 94.6%, 73.7%, and 66.0%, respectively. 39.3% of the students answered that they had a lot of difficulty in understanding general chemistry. The characteristics of learners who make it difficult to understand the content were found to be 'lack of willingness to learn' such as 'lack of understanding chemical concepts' and 'lack of problem solving', due to the lack of 'basic knowledge'. As a way to solve these difficulties, 'expert help' appeared the most. The grades of general chemistry of students who entered the regular admission were relatively higher than those of occasional recruitment.

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].

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 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.

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.

These days, much information is provided as a list of summaries through mobile services. In this regard, users consume information in which they are interested by observing the list and not by expressing their interest explicitly or implicitly through rating content or clicking links. Therefore, to appropriately model a user's interest, it is necessary to detect latent interest content. In this study, we propose a method for reasoning latent interest of a user by analyzing mobile content consumption logs of the user. Specifically, since erroneous reasoning will drastically degrade service quality, a unanimity ensemble method is adopted to maximize precision. In this method, an item is determined as the subject of latent interest only when multiple classifiers considering various aspects of the log unanimously agree. Accurate reasoning of latent interest will contribute to enhancing the quality of personalized services such as interest-based recommendation systems.
