The primary school mathematics emphasizes some activities such as visualizing figures, drawing figures and comparing figures from various angles. These activities could be undertaken throughout examination, experiments and exploration of the substantial materials. They could also be undertaken by using the objects found in a daily life informally. The 7th curriculum of mathematics reflects this trend and includes the systematized activities in teaching spatial sense in geometry. However, it still requires more researches on the teaching methodology of spatial sense and the conceptual analysis of spatial sense. In this study, the concept of spatial sense is analyzed and Mackim's 3-levels teaching methodology and Bruner's EIS theory and suggestions are reviewed as a possible teaching methodology of spatial tasks. As a conclusion, this study suggests a teaching-learning methodology of spatial tasks at the levels of 2-GA and 3-Ga of the 7th curriculum of mathematics.

Online community as a business model has gotten much attention in online market. And it has been recognized as an increasingly important tool for better understanding and relationships with customers. Thus, There are needs for conducting researches, such as those being performed in social psychology area. Due to the lack of current researches on online community, variables that have been considered in social science and factors in relationship marketing are adopted in this study. The primary purpose of this research is to develop and test a model that explains the process of how sense of online community through relationship quality influences customer loyalty. The major findings of this study are as follows: First, sense of online community was found to have a positive influence on relationship quality. Second, relationship quality was found to have a strong positive effect on customer loyalty. Finally, relationship quality was found to have a mediation effect between the sense of online community and the customer loyalty. Implications of these findings are discussed for researchers and practitioners.

The furniture of the Joseon era, life sense of human forms a culture has appeared well. Feeling of life refers to the sense of feel natural to the history and traditional culture of the area and their own customs. Further, it is possible to be a sense that reflects the mental contents ego, ethical and religious. Furniture traditional and sophisticated sense like this is to take care of the sophistication that comes out from the inside than the beauty artificial as a function of the sense and user preferences. This is a feeling of unique Korean. Due to changes in the housing, the beauty of these illustrates the altered form mechanically a uniform in modern times. Have that desired to be manufactured furniture by applying the neck Korean furniture of our living environment that will change in Western Europe of today, with the tradition of the modern lifestyle.

This paper proposes a sense amplifier with non-volatile memory in order to improve the image quality of LCD by enhancing the matching of the driving voltages between the panel and driver. The sense amplifier having a wide sensing margin and fast response adjusts LCD driver voltage of display driver. The CSTN-LCD with the sense amplifier results improved image quality than that with conventional 6 bit column driver without it.

The purposes of this study were (a) to compare the level of sense of community and community activity of the mixed-use residential buildings' residents with the expected residents for the mixed-use residential building, (b) and to investigate the degree of their needs of social interaction. For the survey the questionnaire from 176 residents of mixes-use residential building in Seoul, and 67 expected residents in Bundang Newtown are used. The analytical methods adopted in this study were frequency, percentage, chi-square test and t-test. It was found that the level of sense of community and the community activities of the mixed-use residential building' residents were higher than those of the expected residents. Their residents reported higher degree of participation on community activities than the expected residents. It was also found that the common space in their residential area promoted the residents' sense of community and community activity.

For fast MRI, the number of phase encoding steps has to be reduced. However, the reconstructed image is aliased if the phase encoding steps don't satisfy Nyquist sampling theory. SENSE is used in order to eliminate the aliasing effect as well as to reduce imaging time. SENSE is a linear algebraic technique applied to the multiple receiver data. In this study, we implement a tool to reconstruct the original image (SENSE image) with Sensitivity Encoding (SENSE)

This paper proposes a novel CTC technology, CB-sense. The CB-sense guarantees a dedicated period for the CTC that results in low duty cycle of the receiver device. In addition, it send a lot of information explosively during the dedicated CTC period. Thus, it can achieve high throughput. The CB-sense uses Clear to Send (CTS) packets to transmit information bits to the heterogeneous wireless technologies. The CTS packets block the neighboring node transmissions, so it reduces co-channel interference. In experiment results, CB-sense represents 20 times more throughput than FreeBee and below 5% symbol error rate in the interference environment.

Not all parents are skilled in scaffolding their young children's numeracy learning. The present study investigated the effectiveness of a parent training program in promoting Filipino young children's number sense via card game playing at home. Participants were 161 young children and their parents; families were of a relatively low socioeconomic status. During the 10-week intervention period, parents in the experimental group received training on how to use number game cards to help their children acquire various numeracy concepts; parents in the control group received no special instructions. Children in the experimental group showed greater improvements in their performance on six number sense tasks (namely numeral identification, object counting, rote counting, missing number, numerical magnitude comparison, and addition) over the intervention period than did children in the control group. Findings of the present study suggest that providing simple training to parents on strategies for fostering their young children's number sense at home is important for giving children a good early start in basic number knowledge.

Most researches on word sense disambiguation have used static sized context regardless of sentence patterns. This paper proposes to use dynamic sized context considering sentence patterns and distance between words for word sense disambiguation. We evaluated our system 12 words in 32,735sentences with Sejong POS and sense tagged corpus, and dynamic sized context showed 92.2% average accuracy for predicates, which is better than accuracy of static sized context.

Having developed a parent education program for guidance of internet-using children, we evaluated the effectiveness of this program. The program consisted of five two-hour sessions. It was test-run with nineteen participants, which included mothers of elementary school children. In the evaluation of the program, we employed so-called 'pretest-posttest control group design' which compares the difference in the parenting sense of competence, parents' sense of role satisfaction, parents' sense of insecurity, and parents' rearing attitudes between the experimental group and the control group. Program evaluation revealed that the parenting sense of competence and role satisfaction increased in the group that participated in the program compared to the non-participating group. Furthermore, the parents' sense of insecurity decreased and democratic rearing attitudes were fostered in the participating group.
