The purpose of this study is to investigate the characteristics of the mind maps which were drawn with pencil or color pens by elementary students. For this study, 31 students of the 6th grade were selected and trained mind mapping. After training, the subjects had drawn mind maps with color pens about the ROCK for 15minutes and drew mind maps with pencil after 2days of mind mapping using color pens. In addition to activities of mind mapping, the students handed in their papers which were written one's impression of drawing two kinds of mind mapping. The results were follows: First, in central circle which was linked words connected firstly with ROCK as key word, the difference of 2kinds mind maps were little showed in the quantity and quality of the words, branches and their adequacy. Second, the mind maps using pencils had more words, branches and images than mind maps of using color pens in the whole assessment. Third, the most students suggested that the mind mapping using pencil were advantage to economy of time, retouching words and branches, also the mind mapping using pencil made the students relax the strain for drawing it because of retouching possibility. Consequently, the results of this study suggest the mind mapping using pencil has advantage effect on the purpose of gaining students' thinking abundantly and economy of time in elementary science classes.

Cultural tourism product that has its theme of Taekwondo which is the representative traditional martial arts of Korea possessing over 50 million people doing Taekwondo worldwide has high marketability and usefulness. By this, the researcher is trying to implement design development expecting transition to new perception on the cultural product by qualitative growth of productivity quality, popularization of crafted products, comsumer oriented product development by deciding cultural product production fit for Taekwondo concept based on the participation of tourism activity of Taekwondo institute by visitors and tourists of Taekwondo institute. Firstly, storybook containing spirit and story of Taekwondo, secondly general rack for pencils or candles, thirdly mini memo in universal price which is practical and sophisticated. With the perception of necessity and possibility to use Taekwondo-related cultural tourist product, by aggressively using the product as the souvenir of Muju Taekwondo institute to promote Taekwondo, we hope that the product will help to create value, which differs from existing cultural tourist products.

The purpose of this study was to investigate children's Perception of parenting attitude parent and learned helplessness on addictive use of computer game. The data was collected through paper-pencils surveys with 745 students who are attending the 4, 5, and 6 grade of three elementary schools. The instrument used to see how they looked at the parenting attitude of their was Ji-hyun Hwang(2006)'s Perceived Parenting Attitude Inventory, Chang-woo Song(1997)'s Learned Helplessness, and Internet Game Addiction Test by developed Korean Agency Digital Apportunity & Promotion. Statistics and methods used for the data analysis were Cronbach'a alpha, freuency, percentage, Two-Way ANOVA, Pearson's Correlation, and Regression by using SPSS WIN 12.0. The results of this study is described as follows. In this study, prevalence of computer addiction tendency and addiction is 14.3%. Male students showed highest computer addiction game than female students.

This study is a study on the methodology and possibility of making more creative 'Zentangle Art' works through the effective convergence of digital art during the process of Zentangle Art' which draws patterns using writing instruments such as analog pencils and pens to be. In particular, we studied the convergence of traditional pattern and 'Zentangle Art' by applying the method of making using digital author's authoring tool and the pattern symbol of Korean traditional pattern. And It was studied and analyzed in terms of semiotics. In the future, I intend to study the psychological phenomenon and characteristics of the artist during the production of the works. Later, Zentangle artists and researchers will be presenting the continuing direction of content creation and industrial value.

A new study was carried out to utilize a pencil drawing paper sensor (PDPS), which drew a line using a pencil on the paper, as a sensor. The sensing effect on 3 different papers based on the properties of PDPS was compared. The specimens were prepared by drawing 4B pencils on plain (A4), Hwasun, and Han papers. The silver paste was used to give good electrical contacts of the copper wires and the pencil drawn line. The chemical structures of 3 papers for PDPS by FT-IR spectrum analysis were similar and the comparative compact states of each paper were observed by optical microscope. From statistical evaluation of tensile strength using 3 papers, plain paper was chosen to be best for the PDPD. The optimum drawing number of PDPD was determined by changing the thickness of the paper with the drawing number. Electrical resistance (ER) with graphite on 3 different papers were compared. The changes in compression was observed through cyclic compressive test of composite materials, it was possible to predict the degree of strain sensing under compressive test. It leads to expectation of properties.

The purpose of this study was to investigate the effects of mathematical instruction using GSP program on the symmetrical figures learning and self-directed learning attitude. According to the pretest result, the experiment group and the comparison group showed to be homogeneous groups. The experiment group has learned symmetrical figures for 9 hours using the GSP program and the comparison group has learned for 9 hours using the traditional method(paper and pen lesson). As the posttests, self-directed learning attitude test and symmetry figure understanding test were performed. The results obtained in this research are as follows; First, there was a significant difference in symmetry figure understanding test between the experiment group which learned through GSP program and the comparison group which learned through traditional method. Since there showed a very high achievement in the experiment group which learned using GSP, it can be inferred that GSP was very effective in the lessons of symmetrical movements. Second, there was a significant difference in self-directed learning attitude test between the experiment group and the comparison group. This seems to be because the length of the sides of the figures, size of the angles of the figures etc can be verified instantly and the students can correct by themselves and give feedbacks when they use GSP program. Students preferred drawing using the GSP over drawing using rulers and pencils, and they showed interest in the GSP program and they did not have burden in being wrong in their study and studied in various methods. And as they become familiar with the GSP program, they even studied other contents beyond the scope presented in the textbook.
