  • In most pattern recognition and image understanding applications, images are degraded by noise and other distortions. Therefore, it is more relevant to decide how similar two objects are rather than to decide whether the two are exactly the same. In this paper, we propose a method for recognizing degraded symbols using a distance measure between two graphs representing the symbols. a symbol is represented as a graph consisting of nodes and edges based on the run graph concept. The graph is then transformed into a reference model graph with production rule containing the embedding transform. The symbols are recognized by using the distance measure which is estimated by using the number of production rules used and the structural homomorphism between a transformed graph and a model graph. the proposed approach is applies to the recognition of non-note musical symbols and the result are given.

  • In modern mathematic education, the development of mathematical ability based on the understanding of mathematical concepts has been emphasized in curriculum and teaching methodology. Also, in schools, most math teachers stress the importance of mathematical concepts in doing math well. Thus, in this paper, we outlined the development of mathematical concepts through the literature survey. And then, based on the Sfard's definition of mathematical concepts, which classifies math concepts into the operational approach and structural approach, we analyzed the math concepts of exponential function and logarithmic function units in three highschool math textbooks. As the result, we found that the textbook authors used different approach for the same concepts, and, at the same time, they used both approaches to help develop the students' math concepts.

  • The objective of this study is to search the recognition of teacher on the pattern and characteristics of the questioning sentence of the newly appointed teachers for the mathematics class through the case study for the 2ndyear teachers. The study participants' class was recorded in video and individual interview was made for 4 times. The pattern of the questioning sentence in the observed class was analyzed using the classification frame with addition of creativity related items to the classification frame suggested by Mogan & Saxton(2006). The questioning sentence and recognition on the mathematics class for the newly appointed teachers were analyzed based on the individual meeting and class materials. In result, the questioning sentence for confirmation was most frequent (69%) and questioning sentence of understanding (25%) and the questioning sentence for introspection (6%) in its priority. It was known that the questioning sentence for extending the creativity didn't make it at all. It was revealed that the participant teachers in this study used the questioning sentence pattern for fact confirmation of the student most frequently and the use of the questioning sentence for accelerating the creative thinking of the student was lacked. In addition, the teachers recognized that they manage the class oriented to questioning sentence for obtaining the concept. It was known that the education for the questioning sentence which accelerates the creativity and other thinking as well as the fact confirmation pattern is necessary through the training for the new teachers in the future.

  • The purpose of this study is to develop conceptualization models of reading, information, ICT, and digital literacy through conceptual differences of these literacy by reviewing and defining the concepts of literacy as well as reading, information, ICT, and digital literacy. Computer literacy has emerged as a concept that explains the phenomenon of contemporary social, cultural, and information technology development, and since then, computer literacy has since changed to IT, ICT literacy, and digital literacy. As a result of the study, a conceptualization model of the reading, information, ICT, and digital literacy was developed. In this model, these literacy whose terms have changed according to the technological development of media, have been classified as medium-centered literacy. And reading and information literacy that focuses on the cognitive process of understanding, utilizing, and evaluating texts and information is categorized as process-oriented literacy. In the digital environment, reading and information literacy is a core competence to critically think and evaluate the texts that are on media, and further research is needed to reduce the reading and the information gap among readers.

Therefore, when it comes to fashion trends reflected in collections, the study is designed to improve understanding of make-up as one of the elements of total fashion and to help create diverse ideas in expressing creative and free make-up that can help perfect fashion concept in harmony with all the other elements. The study has pondered upon collection, trends and fashion make-up through literature study, and has gathered image data via the Internet. It also has conducted analysis of Ethnic style reconstructed combining past and the future, East and the West, and futurism style using asymmetrical forms without no defined patterns and hi-tech textures, which emerges as a result of post-modernism. The results of the study are as follows. Ethnic fashion that pursues strange and exotic beauty is characterized by its simple and idyllic images of traditional costume in Asia or primitive clothes in Africa. Make-up represent images of matt and pale skin, tanned yellow, glossy and thickly powered squeaky white skin. Point make-up highlighted eye lines, red chick, small and voluptuous red lips. Hair and accessory seeks diversity combining various ethnic styles together such as oriental, Indian, Islam and Africa.

  • The intention of this paper is to give a better understanding about the implementation of sustainable manufacturing practice in the textile companies in Indonesia as one of the promising sectors in the manufacturing industry. The data was collected by taking a case study approach in one of the leading textile companies in Indonesia. Questionnaire and interview techniques were used to gather in-depth information about the implementation of a sustainable concept in the company. The result reveals that the extent of the implementation of Sustainable Manufacturing Practices (SMP) in the companies are at a level of moderate to high. From the three dimensions measured which are environment, economy, and social dimensions, the evaluation result shows good performance in terms of the implementation of sustainable concepts, like low level of gas emission, high percentage of renewable energy usage, cost reduction rate, high quality of life, etc. From this result, the authors then develop a sustainable manufacturing model in the wider coverage to be implemented not only in the textile industry but is expected to be implemented in manufacturing sectors as well. This model consists of at least seven basic archetypes which are divided into three dominant areas: technological innovation, economical, and social areas which aim to bring better performance in the manufacturing industry of Indonesia.

  • This paper presents the need for the concept of collective intelligence based system for the timely learning and incorrect notes show the utilization and satisfaction. The old wrong answer note system is characterized by the provision of uniform right answer explanations for the questions whose answers were wrong by checking whether the evaluation items were answered right or wrong. The characteristic requires a lot of improvements in terms of wrong answer analysis and feedback since it cannot properly receive feedback on the items that a learner got right by luck in spite of poor understanding of them and on the errors in the selection process of wrong answers by individual learners. The SERO wrong answer note was designed to propose new ways to identify and capture such "score errors" and compensate for the practical weaknesses of learners. The Stability Emergency Risk Opportunity (SERO) wrong answer note is based on a method of categorizing and analyzing evaluation items answered by the examinee into four types (S, E, R and O type), and commentary correct as well as incorrect answers by presenting a variety of commentary notes using the collective intelligence of the study show that satisfaction is high.

  • A 'wicked problem' is something that is hard to notice and not easy to perceive. This study focuses on understanding the precise concept of wicked problem through studying the background that led to the introduction of the term wicked problem. On the other hand, for social innovation, which has recently become a hot topic, it is necessary to identify wicked problem. Social innovation means solving in an innovative way that is more effective, efficient and sustainable than existing ones. As the beneficiary is not an individual but a society, it is in line with the field covered by wicked problem. Therefore, the study introduces a case in which wicked problems are solved through novel ways, that is, design thinking. Through the case study, it was confirmed that design thinking helps identifying problems that are not revealed and contributes to social innovation. As a result, we hope that this research will contribute to help solve the problems that we need to resolve in our society by using design thinking.

  • The purpose of this study was to analyze the organizational framework and contents of the clothing design section of the middle school textbook of Technology & Home-economics(1) of the revised curriculum in 2009. The scope this study lies in external characteristics such as framework, contents and the like from the Home Economics area of textbooks by seven publishers chosen from those that were authorized by the Ministry of Education, Science and Technology in 2012. The result showed that the seven textbooks have the same top Unit 'Juvenile Life' and mid-Unit 'Clothing and Self-expression' but that smaller units were different and diverse in content. In the small unit 'Clothing and Self-expression' of the clothing design section, contents are structured to be put into practice by understanding and exercising the concept; the contents are offered as design theories, clothes design, clothing, and activities/investigation. Hanbok (Korean traditional clothes) clothing was proposed in all textbooks in an order of the right way for Hanbok clothing, names of Hanbok, kinds of Hanbok and the order of wearing Hanbok. Accordingly, this study found the seven textbooks were constructed corresponding to the revised curriculum 2009 for the clothing design section of Technology & Home-economics(1). This study suggests students can build their own insight for viewing society, the country and the world as well as appreciate their own importance in establishing consciousness if they go forward in solving the various problems they face in home life by grafting practical reasoning.

  • The purpose of this research was to reduce the burden of household management and the difficulty of rearing children, which are two most important obstacles for a dual-income family. For this, we suggested a cohousing project, as an alternative concept to conventional housing, where people can socially interact with each other and share mutual cooperation for a better quality of life. We surveyed the lifestyle of dual-income families in Korea, how they understood the cohousing project and their opinions on it. We carried out a survey with the wives from dual income families who were living in the metropolitan areas including Seoul. We contacted 30 wives for the survey to determine the reality of the double income couple family and interviewed them to make a detailed plan for cohousing based on their understanding and needs. In the results, many women who responded to the interview agreed that cohousing was an ideal housing arrangement for the dual-income family. However, they were anxious that it would take too much time and effort to develop their own housing estate by themselves. Therefore, we looked for a way to save time, efforts and cost in developing a cohousing project and came up with the remodeling as a solution.
