This research aimed to identify characteristics of housing repairs for the weak class in rural area. Data are analyzed by the status according to year focusing on voluntary activity of the Korean Institute of Rural Architecture that is performing more than 10 years. The results are followings. First, approximately 63.3% of residents living in benefit houses are 70s and 80s in their age. They are weak in financial and physical and they have more than two weak points. Second, housing repairs were performed total 1,990 cases among 797 houses and average 2.5 cases per one house. Repair work in house interior is at the highest, the next is repair work in kitchen, repair work related to restroom, repair work for housing structure improvement, and repair work for insulation in order. Third, repair work required difficult work process and high cost is tend to decrease recently. However, work changing of wallpaper and papered floor and performing in outside is tend to increase because it has simple work process and low cost. Finally, barrier free needs to be more actively reflected for the weak class in rural area.

In an effort to obtain preventive, diagnostic and therpeutic medical and exercise training information of rheumatoid arthritis as well as to provide pertinent data to be used in development of exercise program for the management of rheumatoid arthritis, this study was conducted by using literature review. Because RA is a disease that involves both joints and muscles, its activity in the different functional classes influences the patient's ability to exercise. A patient in Functional Class 1 may perform any type of exercise because the disease involvement has not yet reached major importance. Exceptions may include hard physical exercise, running, and individual racket sports. In almost all cases, bicycle exercise is possible. Patients in Functional Class 2 and a few in Class 3 can perform most types of exercise (especially cycling, walking, heated pool exercise and even jogging) in low activity phases of RA. Although a few patients in Functional Class 3 can walk, jog, and perform similar types of exercise, most persons in this class can swim or exercise on a bicycle if the type of exercise, its intensity, and its range of motion are modified according to the patient's anatomic and pathologic conditions. Most patients in Functional Class 4 are not able to carry out complicated movements. We conclude that physical training for persons with RA has physical, psychological, and social consequences that are clearly beneficial. We recommend training be one part of the many involved in the complicated treatment of RA.

The purpose of this research was to find out if the analogical role-playing class activity had an effect on the students' academic achievements on cellular respirations as well as their science learning motivation for those who took part in the cellular respiration. To examine the effects of applying the activity, the research was conducted targeting a high school with humanities and social sciences courses, located in Busan. The target was specified as two classes that had selected a Biology II class, with one class (27 students) set as the test group and the other class (28 students) set as the control group. The conclusion drawn from this research was as follows: First, it seemed that the analogical role-playing activity helped the students to take their own parts in cellular respiration and gave them an opportunity to explain the concepts through direct physical activities, enhancing their academic achievements. Second, it was concluded that as the students found confidence and relevance in scientific knowledge as well as obtained a sense of accomplishment, the analogical role-playing class activity increased their level of satisfaction and their science learning motives. Third, as a result of the interviews on the change of the concept, students expressed some dissatisfaction over the new concept, and thought of the analogical role-playing activity as an intelligible alternative. It appeared that the alternative was plausible and fruitful.

Background: Immunomodulators enhancing MHC-restricted antigen presentation would affect many cellular immune reactions mediated by T cells or T cell products. However, modulation of MHC-restricted antigen presentation has received little attention as a target for therapeutic immunoregulation. Here, we report that lectins isolated from mushroom Fomitella fraxinea enhance MHC-restricted exogenous antigen presentation in professional antigen presenting cells (APCs). Methods: Lectins, termed FFrL, were isolated from the carpophores of Fomitella fraxinea, and its effects on the class I and class II MHC-restricted presentation of exogenous ovalbumin (OVA) were examined in mouse dendritic cells (DCs) and mouse peritoneal macrophages. The effects of FFrL on the expression of total MHC molecules and the phagocytic activity were also examined in mouse DCs. Results: DCs cultured in the presence of FFrL overnight exhibited enhanced capacity in presenting exogenous OVA in association with class I and class II MHC molecules. FFrL increased slightly the total expression levels of both class I (H-$2K^b$) and class II (I-$A^b$) MHC molecules and the phagocytic activity of DCs. Antigen presentation-enhancing activity of FFrL was also observed in macrophages isolated from mouse peritoneum. Conclusion: Lectins isolated from the carpophores of Fomitella fraxinea increase MHC-restricted exogenous antigen presentation by enhancing intracellular processing events of phagocytosed antigens.

According to the characteristics of elementary school students in favor of playing games, and to their high energy levels and physical growth states, it is fair to say that students can learn mathematics through 'game playing activities.' These activities are considered to intrigue their interest in class and make them feel less stress from the burden of studying mathematics. Mr. Skemp, who had conducted research on 'game activity' with experimental studies relating to elementary mathematics, recommends that math teachers try to give as many activity-oriented classes as possible to students. The method of 'game activity' by Skemp's operation deals with the whole range of mathematical themes. It is believed by other math teachers that this is not a way to substitute free time or just to have fun in class, but an intentionally well-organized way of learning an entire mathematical course during elementary school. In this research, 5th and 6th grade students needing extra classes after school had been exposed to 'ame activity' by Skemp's operation. As a result, we can figure out its influence on their understanding of arithmetic ability, and on the cognitive definition territory in their minds.

This study was investigated on the consciousness of middle school students in Jeju city about the environmental education through questionnaire, in order to understand the actual conditions of environmental education and to find out the solutions about them. Middle 'school students responded that environmental education in school was taken at the class for the special activity or voluntary service, not in regular class and was worked as in the form of the field trip. They generally obtain the knowledge and informations on the environmental problems from mass media such as TV, radio and newspaper than from regular environment class in school. And 36.0% of students perceive that environmental education is needed as a regular class and 31.3% of students perceive that the regular class in school is effective to the environmental education. These results suggest that many students are interested in the regular environment class in school. However, the most of students responded that the regular environment class in school is not worked or is not worked at all, suggesting that the environmental education in middle school is not worked effectively. Most of students prefer to take the environment class in the form of observation or field trip, and they think that observation or field trip is more effective to obtain environmental informations. In conclusion, the special activity such as observation or field trip needs to be supplemented to regular environment class in order to improve the environmental education in middle school more effectively.

This study analysed the result of a survey answered by 120 technology teachers and 360 students from 357 middle schools in Seoul to find out the actual state of safety accidents during technology education activity course in the middle school class and safety awareness of the teachers and students. The result shows that many safety accidents happen during technology education activity course in the middle school class. However, most teachers and students have experienced safety accidents or dangerous situations more than once a year. Technology teachers had very low awareness on the states of retaining safety equipments. On the other hand, they were well aware of the importance of safety, including the actual states of safety education, knowledge of safety, and the will to join safety education. Therefore, safety awareness of technology teachers should be reinforced by the extension of safety training and the improvement of safe environments.

This study was to find the effects of science activity activating spatial ability on spatial ability and creativity of the elementary school students. The survey was conducted with 30 second grade students in one class of "J" elementary school located in "C" City, Chungcheong-bukdo province. The students were taught with the program of science activity activating the spatial ability. According to the result, the science activity had significantly influence on the improvement of spatial ability of the elementary school students. It had also significantly influence on the improvement of spatial relationship ability. The science activity was also effective in the improvement of creativity, and especially in the subdomain of originality and sensitiveness. The students who has right brain preference showed much more improvement in the spatial ability compared to left brain preference students after science activity class. However there is no difference between the students who had the right brain preference and left brain preference in the creativity.
