As part of recent SW education methods, entry sites have been used in all practical textbooks in elementary schools. However, they are all learning block-type programming languages, making it difficult to produce programs that can be used in everyday life. This study is a study on the effects of learning programming using entry python on logical thinking ability and programming interest in elementary school students. Logical thinking ability and programming interest tests were conducted before and after the 8th class. Before and after classes, logical thinking ability score rose from an average of 6.6 to 9.4 and programming interests score also rose from an average of 46.7 to 59.1. This results in programming learning using Entry Python is significant for enhancing the logical thinking ability and programming interest of elementary school students.

The purpose of this study is to acquire teaching insights for improving scientific literacy by analyzing the effects of scientific communication skills, science process skills, and logical thinking skills of elementary school students on academic achievement level. The participants are 64, sixth grade elementary school students. Survey materials include the results of Scientific Communication Skill Test (SCST), Test of Science Process Skills (TSPS), Group Assessment of Logical Thinking (GALT), multiple choice test & short answer test, descriptive answer test on science, and academic achievement level test on all subjects. Based on these data, the study analyzed the relationships of science process skills, logical thinking skills, and scientific communication skills, and each category's effect on academic achievement level. Furthermore, under the assumption that scientific communication skills are affected by science process skills and logical thinking skills and directly influence the academic level, the research discovered three types of correlations as a structural model. The results show that there are considerable correlations in scientific communication skills, science process skills, and logical thinking skills. Also, these three abilities have meaningful correlations with learner's writing and descriptive question level on science curriculum and overall academic achievement level; the level of correlation differ a bit by subcategory factors. In conclusion, setting the model, science process skills and logical thinking skills influence scientific communication skill, and the skill directly influences the learner's academic level. Further analysis of the results show that scientific communication skill influences the academic achievement level of all subjects the most.

At the present time, buildings are designed higher and more complex than ever before. Therefore the potential disasters are happened such as fire, power outage, earthquake, flood, hurricanes. Their disasters require people inside buildings to be evacuated as soon as possible. This paper presents a new disaster evacuation guidance concept of inner buildings, whiche aims at integrated the constructing of a sensor network and a guidance light networks in order to provide a quick detection of disasters and accurate evacuation guidance based on indoor geo-information, and sends these instructions to people. In this paper, we present the integrated logical model based on sensor and guidance light networks for the fire disaster management in inner building using our concept. And we verify proposed logical model according to experiments with visualization and operations on map.

Objective: This study aimed to examine the influences of household chaos on self-control of young children and to investigate whether teachers' limit-setting styles had moderating effects. Methods: The participants were 184 children (83 boys and 101 girls), at age 3 -5, their mothers and teachers working at daycare centers located in Seoul and Gyeonggi-do. The data were analyzed by descriptive statistics, Pearson's correlation, and hierarchical regression. Moderating effects were examined using the Mplus8.0 program. Results: The results indicated that household chaos as well as teacher's permissive and logical limit-setting styles had significant effects on self-control of preschoolers. The lower the level of household chaos was, the higher the level of self-control of preschoolers was. The level of self-control was more likely to be high when teachers used logical limit-setting with detailed explanation to children whereas it was lower when they used more permissive limit-setting. In addition, teachers' logical limit-setting moderated the relation between household chaos and self-control of preschoolers. That is, the effects of household chaos on preschoolers' self-control were mitigated when the level of logical limit-setting was high compared to when it was low. Conclusion/Implications: The results suggested that both household chaos and teachers' limit-setting styles play important roles in increasing self-control of preschoolers.

In these days, XML is a de facto standard language for representing and exchanging data. In order to define the conceptual model of the XML, we need to define the representation rules expressed in the diagram and propose the transformation algorithm that converts the diagram into a logical model of XML. This paper proposes a transformation methodology for generating a logical model from the conceptual model of the XML. We use CMXML as a conceptual model and generate XML schema definition as a logical model. For this, we define transformation rules and data structures for XML schema, and propose a transformation algorithm.

The purpose of the study was to evaluate the effects of the enrichment program for the gifted on gifted childrens development of the logical thinking and science process skills. The enrichment program consists of 200 enrichment courses in language arts, mathematics, sciences, social sciences and thinking for children at the age of 30 months to Grade 8. Enrichment programs are characterized as process-oriented, student-choice available, activities-oriented, open-ended, and interdisciplined. Subjects were 123 gifted children from Grade 1 to 3 at the Korean Academy of Gifted Education (KAGE), whose IQ scores were above 130 at their entry point to KAGE. Children were divided into two groups depending the duration of the program participation. Older Group participated in the program for longer than 13 months, while Newer Group did for shorter than 12 months. Mean of IQs of the two groups were not significantly different. They were tested on Logical Thinking Test and Integrated Process Skills Test revised by KEDI into Korean version in 1991. Descriptive statistics were calculated and group differences were analyzed with t-test, and scheffe test. The main finding were as follows: There were not significant differences between gender. Children in higher grades showed higher level of development. Older groups showed significantly higher level of logical thinking level of development. Older group showed significantly higher level of logical thinking and process skills than the Newer group inspite of the similar IQ levels to each other. The longer the gifted child participate in the enrichment program, the higher the development of childrens thinking skills.

The purpose of this study was to explore North Korean immigrant elementary students' cognitive and affective characteristics related to science education. A total of 68 North Korean immigrant students enrolled in 3 to 6 grades and 133 South Korean students in 4 and 6 grades in 3 South Korean elementary schools participated in the study. A short version of Group Assessment of Logical Thinking(GALT) was used to investigate the students' levels of logical thinking, and the Enjoyment of Science Lessons Scale(ESLS) of the Test of Science Related Attitudes(TOSRA) was administrated to examine their attitudes towards science lessons. The statistical analysis of data revealed that the level of logical thinking of the North Korean immigrant elementary students was very low and that this was also the case for the South Korean students. Especially, the mean score of logical thinking of the North Korean immigrant 6 graders was much lower when compared with that of the South Korean counterparts. For both the North Korean immigrant students and South Korean students, the enjoyment of science lessons decreased as they progressed through higher grades. This decreasing trend, however, turned out to be more serious in the South Korean elementary students. Based on these results, suggestions were presented to help successful science learning of North Korean immigrant elementary students.

A new architecture called the Storage Area Network(SAN) was developed in response to the requirements of high availability of data, scalable growth and system performance In order to use SAN more efficiently, must SAN operating systems support storage virtualization concepts that allow users to view physical storage devices attached to SAN as a large volume virtually. A logical volume manager Days a key role in storage virtualization it realizes the storage virtualization by mapping logical addresses to physical addresses. In this paper, we design and implement an efficient and flexible mapping method for logical volume manager. The mapping method in this paper supports a snapshot that preserves a volume image at certain time and on-line reorganization to allow users to add or remove storage devices to SAN even while the system is running.

Essay education has been multifariously accomplished through school curriculums, private institutions and online education systems. However we can easily find misspellings from students' writing, and them still not being able to describe their own experiences logically and skillfully in schools. In this paper, we propose the web-based essay correction system using mash-up service, ECSUM, implemented for improvement of a students' logical writing ability applying a logical writing correction module with six steps. Using the proposed system, students can obtain logical writing skills using a mash-up service and teachers can help their students to improve their logical ability of self-expression.
