The purpose of this research is to find out whether children's self-efficacy can be improved by sensory activities devised to encourage spirituality. The survey involved 36 children aged 4 to 5. To measure the subjects' self-efficacy, Jeon Inok(1996)'s tool was used. The 18 members of the experimental group attended a program which was dedicated to promoting spirituality by using sensory activities. The program was administered three times a week for four weeks, totaling 12 sessions, each of which contained a type of activity and lasted about fifty minutes. To the 18 members of the control group, the standard child care curriculum was applied. The levels of the subjects' self-efficacy were measured twice, both in the same way, before and after the children participated in the program. The finding reveals that the program which was designed to boost children's spirituality through sensory activities has positive effect on children's self-efficiency - cognitively, socially, emotionally, and physically. The self-efficiency level in the experimental group significantly increased by t=7.17(df=34, p<.001) compared to the control group. So, it can be said that the program dedicated to improving spirituality using sensory activities is more effective than the standard child care curriculum.

The purpose of this study is to compare inquiry activities in science textbooks' physics contents for Korean secondary schools with those of Singapore in order to provide a reference for further improvement of inquiry activities in Korean science textbooks. We analyzed inquiry activities using the framework of Millar et al.(1998) and Chinn & Malhotra (2002). The results of this study are as follows: There are differences between Korean and Singaporean inquiry activities in the area of 'learning objectives', 'students' thinking activities' and 'degree of openness'. In the area of 'learning objectives', the Korean textbooks have more activities associated with the learning of science content than those in Singaporean, whereas the Singaporean textbooks have more activities associated with the processes of scientific inquiry than in Korean textbooks. In the area of 'students' thinking activities', the Singaporean textbooks have activities like 'test a prediction', which Korean textbooks lack. The 'degree of openness' is higher in Singaporean textbooks than in Korean textbooks. And some differences in the area of 'authentic scientific inquiry' between Korean and Singaporean textbooks were also found. While the Korean textbooks do not have any activities associated with 'generating research questions', the Singaporean ones feature such activities. In the area of 'designing studies', the Singaporean textbooks have activities corresponding to 'selecting variables' and 'controlling variables', while the Korean ones never have such activities. The results of this study imply that it is necessary to balance inquiry activities in the area of 'learning objectives', 'students' thinking activities' and 'degree of openness', and to present activities close to authentic scientific inquiry in inquiry activities in textbooks.

The relationship between Mg II emission line and light variation of V711 Tau has been derived to investigate the chromospheric activity on V711 Tau. First, a shape of an optical light curve was compared with that of ultraviolet constructed from the IUE low resolution spectra. Second, the intensities of Mg II k emission lines have been reduced from IUE high resolution spectra. The intensity of Mg II k line was compared with brightness of the UV light curve at given phase. The Mg II line intensity is maximum at the phase $O.^{P}4$ where the light is minimum. The evidence of chromosperic activity is indicated by the intensity variation of the MgII emission line with orbital phase for V711 Tau.

Various types of students activities presented in the clothing part of the current 'Technology Home Economics' middle school textbooks were analyzed to provide basic idea for improving the quality of content of text, which can arouse students' interest and practical use. Analysis was conducted for the units related to clothing contained in 10 different technology & home economics textbooks of 2nd grade middle school students approved by the Ministry of Education under the 7th national curriculum. Types of student activities were categorized based on "size of groups", "type of problems" and "methods of carrying out tasks" and the this study sought to explore future directions for action plans especially in terms of composition of contents, the methods of performance and suggestions. As a result, the volume of each part in clothing & textiles section was investigated. Among them 'dressing' part was found to make up the largest percentage of the clothing unit. And among the six of the detailed contents, "How to Wear Traditional Korean Clothes" and "Functions of Clothes", took up the largest space. In additions, the types of students activities and methods of implementing and how to performing tasks vary depending on publishing companies and detailed contents of areas. As a result, 'individual activities', 'structured problem', and 'problems that require prior home-based experience' were most common types of activities. Based on this study, it is suggested to increase the number of small group activities and the activities that require diverse problem-solving methods.
