  • The information of figures in science which could induce interest in science and have educational importance is the value-added content through information sharing and connectivity. In this study, we analyzed domestic and overseas cases of Linked Open Data(LOD) that are being increased recently in order to provide a better service through information sharing and utilization of scientific figures. We suggested an efficient scientific figures ontology and the method for LOD construction reflecting the results of the analysis. We also presented plans for the interlinking among various external resources and for promoting LOD information use.

  • In this study, the figure of domestic hardwood was observed using the naked eye and the possibility of substituting imported wood with domestic one in the making woodcraft or furniture was investigated. It was known from the investigation on 8 different hardwoods that there were various figures such as cloud-shaped figure, blister figure, crotch figure, bird's eye figure, etc. in Zelkova serrata wood and the beautiful pigment figure in Diospyros Kaki wood. There were the unusual figures such as wavy grain figure, fiddle back figure, etc. in Cedrela sinensis wood and was clear ray-fleck figure in Quercus variabilis wood. There were also various figures such as wavy grain figure, blister figure, pigment figure, etc. in Sophra japonica, Tilia amurensis, Castanea crenata, Kalopanax septemlobus wood, etc. It is thus that distinguished figures appeared in each kind of wood can be used for craft, sculpture, furniture, and interior material. These kinds of figures can also be used for instrument, toy, stationery, life article material and souvenir, etc. And it can be expected that they will replace the imported wood has been mainly used to make the woodcraft or furniture until now.

  • This study examined the illustrations in the elementary school textbooks which was followed by identifying the parts that displayed gender-discriminating elements or traditional gender roles. The research results are as follows: 1) The ratio of man and woman in the figures appearing in those illustrations was 1.33:1, which means there were more men than women in the illustrations and that there was no balance in the gender distribution among the figures. 2) Male figures were presented as the protagonists in 39.7% of the illustrations, female figures in 25.5%, and both male and female figures in 34.8%. The results indicate that there were much more illustrations in which men were the protagonists than those in which women were. 3) The occupations of the adults in the illustrations were analyzed. As a result, the ratio of man and woman with a job was about 2:1, which implies that there were twice as many male professionals than female ones. Men had over 60 kinds of occupations and women had only 45 kinds of occupations with 59.5% of them concentrated in four jobs including teaching, farming and fishing, doing artistic works, and selling things. 4) The case analysis results of the illustrations in the textbooks demonstrate that the traditional gender roles of a father and mother were followed and that there were gender stereotypes in describing the characteristics of man and woman. Gender dichotomy was observed in the vocations. Men were the leading players in economic, political, and cultural activities, and most of the historical figures were men. Meanwhile, women were depicted as the subjects of economic activities and completely isolated and alienated from political, historical, and cultural activities. It turned out that the figures of the illustrations in the current elementary school textbooks had gender discriminating elements and profoundly reflected the stereotypes for gender roles.

  • For the purpose of using the guideline to evaluate the grassland based on the botanical composition, a valuation figures which were expressed of nine division scale from 0, very poor to 8, excellent were given to the each , grassland species. At first, a figure was given to the 14 1 herbage plants at the grassland in Korea. Fodder value of the grassland was calculated from these valuation figures of the different species and the DM percentages of each plants which was got by analysis or estimation, were only to be multiplied by the different valuation figures and then the sum of these products divided by hundred. It is suggested that the fodder value of the grassland is not only possible to express the botanical conditions of various experiments in some simple figures, but also compare with different types of grassland at the same time.

  • The purpose of this study was to investigate the effects of an instruction using geologic planar figures on high school students' ability of spatial visualization and geologic spatial ability and also to explore its applicability as an instructional strategy through the investigation of students' perception about the instruction using mixed methodology. For this purpose, we developed 10 planar figures of geologic structures (2 horizontal layers, 2 vertical layers, 4 angular layers, 1 fault, and 1 fold), and tested students' spatial visualization ability and geologic spatial ability before and after the implementation in class. In addition, in order to investigate students' perception on the instruction, we conducted quantitative research using questionnaires comprised of the cognitive and the affective domain, and followed by focus group interview that was conducted to obtain deeper understanding of their perception. Findings revealed that the instruction using geologic planar figures was effective to enhance spatial visualization ability and geologic spatial ability. It was also helpful for students to enhance their ability to perceive the spatial configuration of the geologic structures as well as the ability to penetrate visually into the images of the structures. The results of the students' perception on the instruction showed that the students recognized the instruction using geologic planar figures as a strongly positive teaching method both in the cognitive and affective domain. We concluded that geologic planar figures could be used as an effective tool for the lesson of 'mapping and interpreting of geological map', and be highly applicable for the advanced class in high schools.

  • Using social network analysis, this study examined cognitive representations of ideal public figures as well as politicians and entertainers who are often regarded as public figures in Korea. Participants expected ideal public figures to possess only positive characteristics, such as high morality, integrity, competence. However, their assessment of politicians and entertainers reflected in their cognitive representations turned out to be fairly different from the image of ideal public figures. Personality traits and behavioral characteristics featured in cognitive representations of politicians were dominantly negative. Cognitive representations of entertainers incorporated both positive and negative characteristics highly interconnected to each other. This study also explored how people respond affectively toward ideal public figures, politicians and entertainers. Participants showed only positive feelings toward ideal public figures. However, their' affective responses toward politicians were entirely negative and toward entertainers, both positive and negative affects were shown. We discussed the disjunction between the representations of politicians and entertainers and of ideal public figures and suggested directions of future research.

  • This study examines the demand for agricultural information at farm level, using Probit and Logit models. 646 farmers are surveyed with a questionnaire to attain the data and 441 of them have responded. The demand functions for computers, agricultural softwares, and agricultural databases at from level have been derived and used to project the demand for agricultural information in year $2001{\sim}2004$. Results find that only 5.89% of farmers have PCs at farm and rarely use the agricultural databases and softwares in 1994. The low demand figures are mostly due to the difficulty of using the PCs, databases, and softwares. The demand figures will increase in early 2000`s with 15.46% of farmers having PCs. User Friendly developed softwares and databases, and education for using agricultural information are necessary to increase the demand figures.

  • The purpose of this study was quantitative and qualitative contents analysis of food and nutrition section in middle school textbooks of home economics, physical education and science. As a quantitative approach numbers of sentence lines tables, figures, photos, activities, and exercises were counted. As a qualitative approach, types of explanations were categorized by 7 criteria, and commons and differences of the contents of those subjects were compared. The conclusions of this study were summarized as follows: 1) Contents of food and nutrition section were divided into nutrients. water. energy, food groups, and nutritional problems. When average sentence lines of each were compared, those of nutrients were the longest in all 3 subjects. 2) When compared the numbers of tables, figures, and photos in 3 subjects of textbooks, there were more figures in home economics and science, and more tables in physical education. 3) There were more activities and exercises in home economics an science than in physical education. 4) The D(sentences with table) or E type(sentences with figure) was adapted for the explanation of nutrients functions, recommended dietary allowance, food sources, food groups, eating habits, and weight control in home economics: nutritions functions and energy metabolism in physical education : and digestion, body constituents, energy metabolism, and detection of nutrients in science. 5) Contents about classification and functions of nutrients. food sources deficiency water, energy contents of nutrients and obesity were shown in all 3 subjects. Food groups and eating habits were explained in detail in home economics whereas digestion of nutrients in the digestive tracts were explained in detail in science. Recommended dietary allowance for Koreans and basic food groups revised in 1995 were presented in home economics, whereas those revised in 1989 were presented in physical education. To avoid confusion, recommended dietary allowance for Koreans and food groups presented in physical education tex should be updated.

  • The purpose of this study is to analyze the seventh curriculum textbooks and teacher's guides of high school science courses in relation to the generation (mechanism) of magma in subduction boundary and find the incorrect descriptions of the texts and the figures (illustrations) and then suggest some improved schemes. According to the result there are many discrepancies in definition of 'magma' among the textbooks and further little scientific explanations about the formation mechanism of magma in most textbooks, and even no descriptions about that. In addition, the figures are inconsistent with the description of the text and also have some incorrect depiction which might contribute to the forming and reinforcing misconceptions about Plate Tectonics as well as a volcanic activity in subduction boundary. On the basis of the previous researches, therefore, some improved schemes (text descriptions and figures) are suggested. The results of this study should be used as a reference for publishing science textbook, developing science curriculum, and teaching effectively in the high school.

  • We present a new method for an automated markerless system to describe, analyze, and classify human gait motion. The automated system consists of three stages: I) detection and extraction of the moving human body and its contour from image sequences, ii) extraction of gait figures by the joint angles and body points, and iii) analysis of motion parameters and feature extraction for classifying human gait. A sequential set of 2D stick figures is used to represent the human gait motion, and the features based on motion parameters are determined from the sequence of extracted gait figures. Then, a k-nearest neighbor classifier is used to classify the gait patterns. In experiments, this provides an alternative estimate of biomechanical parameters on a large population of subjects, suggesting that the estimate of variance by marker-based techniques appeared generous. This is a very effective and well-defined representation method for analyzing the gait motion. As such, the markerless approach confirms uniqueness of the gait as earlier studies and encourages further development along these lines.
