This study explores the types of daily routines in child care centers based on the time planned for indoor free choice activities, outdoor activities, group activities and nap/rest. The daily routine plans of 63 classes of 0 to 2-year-olds and 51 classes of 3 to 5-year-olds were cluster analyzed. Also, openness and closeness of child care programs as well as the most participated indoor/outdoor activities were examined using questionnaires developed for teachers. The results were as follows: First, teachers planned the most time for free play choice activity and comparatively less time for outdoor play during the day. Time for rest and naps were planned more for 0-2 year-olds whereas group activities were planned more for the 3-5 year-olds. Second, 3 daily routine types were found in the daily plans of child care centers, such as "Low-Activity Oriented," "Free Choice Activity Oriented" and "Group Activity Oriented" in 0 to 2-year-old classes and 3 to 5-year-old classes. Also, "Group Activity Oriented" type in 0 to 2-year-old classes showed more "closed" child care programs than the "Free Choice Activity Oriented" type. However, no difference was shown among the 3 types of daily routines in the openness and closeness of 3 to 5-year-old child care programs. Finally, all children, regardless of the types of daily routine, participated most in block activity and role play indoors and fixed-play equipment, sand play and free play outdoors.

The purpose of this study is to clarify the characteristics between the type of daily routine and spatial configuration of activity areas in classroom and provide alternatives for space planning of activity areas in classroom of child-care centers. This study used the content analysis on daily activity plan and floor plans through field survey. Analysis on floor plans was conducted for 35 classrooms in 9 child-care centers which allowed field survey. The results of this study were as follows; There was no significant difference for classroom size according to the type of daily routine in 3 to 5-year-old classrooms. The average size of classrooms was $61.6m^2$ for care oriented type, $41.4m^2$ for indoor activity oriented type and $48.8m^2$ for group activity oriented type. There was no significant difference in composition of activity areas in classrooms according to the type of daily routine. In case of 0 to 2-year-old classrooms, they were composed of 6 activity areas including gross-motor, role play, block building, language, creative expression, exploration/manipulation. Activity area of the most low frequency was gross-motor area. In case of 3 to 5-year-old classrooms, most classrooms were composed of all the 7 activity areas including art, tone and rhythmic, block building, role play, language, math and science. Most accessible and central areas in 0 to 2-year-old classrooms were gross-motor and role play. Also, most separate areas were exploration/manipulation and block building. Most accessible and central areas in 3 to 5-year-old classroom were art and math. Also, most separate areas were tone and rhythmic and science.

The purposes of this study were to classify purchaser into three groups by purchasing price for preschool children's wear and to identify the differences of clothing values, lifestyles, considerations in purchasing preschool children's wears, and purchasing places among the classified three groups. One hundred forty people living in Seoul with children aging between 3 and 7 were surveyed for this study. Cluster analysis, frequency analysis, chi-square analysis, ANOVA, and scheffe test were used to analyze the data. The findings of this study were as follows; 1) Purchaser were classified into three groups, namely the group of high purchasing price(HP), the group of medium purchasing price(MP), and the low purchasing price(LP). The HP had more monthly average income than the LP. 2) The HP showed high concerns in aesthetic and social clothing values, the MP considered social clothing value more important, while the LP showed high concern in economic clothing value. 3) Regarding the differences in lifestyles, the HP was more fashion-oriented and leisure-oriented, the MP was fashion-oriented, while the LP was economy-oriented. 4) When purchasing preschool children's wear, the HP showed high concerns in design and brand, the MP in activity, laundry-and-care, and brand, and the LP in activity, laundry-and-care, and price. The HP mainly purchased preschool children's wears in department store and imported goods store, the MP in department store, traditional market, and discount store, and the LP in discount store.

This study was performed to identify the proliferation and to measure the alteration of alkaline phosphatase activity in human gingival fibroblasts cultured. For the present study, the authors cultured the human gingival fibroblasts oriented from the sound interdental gingiva, and used third passage. It was used methyl $[^3H]$ Thymidine to identify the proliferation in human gingival fibroblasts and used 410nm of the spectrophotometer to measure the alteration of the alkaline phosphatase activity in human gingival fibroblasts. The results were as follows: 1. There was a statistically significant increase in the proliferation of gingival fibroblasts following low level laser irradiation at 24 hour(p<0.05). 2. There was a statistically significant increase in activity of alkaline phosphatase compared to control group at 5-day laser irradiation after in laser irradiation groups(p<0.05). And there was a statistically significant increase in activity of alkaline phosphatase compared to control group at 7-day laser irradiation after in the I-minute laser irradiation group(p<0.05), but there was a statistically significant decrease in activity of alkaline phosphatase compared to 1minute laser irradiation group at 7-day laser irradiation in the 2-minute laser irradiation group after(p<0.05). The results, within the limits of the present experiments, suggest that, the low level laser irradiation accelerates the proliferation of gingival fibroblasts and alters the alkaline phosphatase activity until the restricted period.

A large number of MJO skill metrics and process-oriented MJO simulation metrics have been developed by previous studies including the MJO Working Group and Task Force. To assess models' successes and shortcomings in the MJO simulation, a standardized set of diagnostics with the additional set of dynamics-oriented diagnostics are applied. The Global Coupled (GC) model developed for the operation of the climate prediction system is used with the comparison between the GC2 and GC3.1. Two GC models successfully capture three-dimensional dynamic and thermodynamic structure as well as coherent eastward propagation from the reference regions of the Indian Ocean and the western Pacific. The low-level moisture convergence (LLMC) ahead of the MJO deep convection, the low-level westerly and easterly associated with the coupled Rossby-Kelvin wave and the upper-level divergence are simulated successfully. The GC3.1 model simulates a better three-dimensional structure of MJO and thus reproduces more realistic eastward propagation. In GC2, the MJO convection following the LLMC near and east of the Maritime Continent is much weaker than observation and has an asymmetric distribution of both low and upper-level circulation anomalies. The common shortcomings of GC2 and GC3.1 are revealed in the shorter MJO periods and relatively weak LLMC as well as convective activity over the western Indian Ocean.

This study investigates how well pre-teachers in preschools aware the importance of science teaching methods, goals and efficacy, and how different the pre-teachers recognize the importance of methods and goals in science teaching according to the levels of their science teaching efficacy. The subjects were 207 pre-service preschool teachers in Chonnam University and Chonbuk University. The data were collected by using three questionnaires("Science teaching efficacy", "Science teaching goal" and "Science teaching method"). The data were analyzed by a t-test and descriptive statistic. The results are as follows: first, the efficacy levels of the pre-teachers are higher than the average. The pre-teachers perceive a 'process-oriented' goal more importantly than a 'content-oriented' goal in early science education. Also, they recognize science teaching methods as being significant in the order of an 'interactive' approach, an 'activity-discovery' approach and a 'knowledge-transmission' approach. Second, the pre-teachers with high teaching efficacy recognize a 'process-oriented' goal as being more important than those with low teaching efficacy do.

As Android platform and its applications are widely used, it is necessary to assure the reliability and safety of Android applications. The capture and replay technique is widely used for reproducing the crashes in Java applications. In this paper, we adapt the context-based capture and replay technique to Android applications by considering Android activity structure and its GUI characteristics. Our capture and replay technique uses probe code insertion based on AspectJ for minimizing the original code change and for enhancing the efficiency and reusability of the probe codes. For proving the efficiency of our technique, we provide a case study and execution overhead comparisons with related works, in which our approach has merits in GUI oriented Android applications with relatively low execution overhead.

This study was conducted to investigate the antecedents of teachers' science teaching efficacy in day-care setting. Also, this study aimed to identify relationships between day-care teachers' personal science teaching efficacy and their perspectives on early childhood science education. The subjects were 176 day-care teachers in rural area of ChoongCheongNam-Do. The survey method was used to collect data from the day-care teacher. The instrument were Rigg & Enochs(1990)'s Science Teaching Efficacy Belief and Kim(l998)'s scales for the Goa1s in Early Childhood Science Education. Main results were as follows: 1. Day-care teachers' personal science teaching efficacy were significantly related with the personal variables such as teachers' education, in-service science workshops, science book reading, science-related hobby but not with teachers' age, pre-service science credits and total years of teaching experience. 2. Among the environmental variables, science activity areas were significantly associated with day-care teachers' personal science teaching efficacy. However, location of day-care center, age of children, number of children, teacher-child ratio, facilities for science education and scheduled time for science education did not affect it. 3. Day-care teachers of high content- and process-oriented goals in early childhood science education were highly efficacious teacher, while the teachers of low content- and process-oriented perspectives gained the lowest score. However, the content-oriented teachers and the process-oriented teachers did not differ in terms of day-care teachers' personal science teaching efficacy.

This study investigates the relevance between the subjective age and clothing shopping orientation by adults women located in the cities of Seoul and Gyeonggi. The results are following. First, subjective age was identified with interest age, look age, and physical age. Customers were segmented into following five subdivisions: young activity group, actual age group, young appearance group, physical aging group and youth-oriented group. When the study examined differences between real age and subjective age, the study could see that they perceived themselves younger four years than real age- 50s: 7 years, 40s: 5 years, the latter half of 30s: 2.7 years and the former half of 30s: 1.7 years. Second, clothing shopping orientation was identified with planned shopping orientation, leisure shopping orientation, loyal shopping orientation, economic shopping orientation and convenient shopping orientation. Customers were segmented into following three subdivisions: shopping low-involved group, loyal leisure group and planned leisure oriented group. Third, interest age was of no relevance to clothing shopping orientation. On the other hand, look age had negative correlation with leisure shopping orientation and convenient shopping orientation and physical age had a negative relationship with leisure shopping orientation and loyal shopping orientation but had positive correlation with economic shopping orientation. Fourth, in clothing purchase, clothing purchase answerers who were younger five years than actual age had the highest frequency. It means that they purchase clothing according to subjective age perceived younger four years on average.
