This is a study on methods for designers of furniture and products to generate and develop design concept in consideration of design and existing conditions of the space when they design street furniture. In particular, in case when they participate in a process of designing new space, this study aims to reveal methods generating strategic elements and basic ideas for designing street furniture through cases study of projects by understanding and analyzing concept of overall space design and by extracting artistic elements for deployment of specific designs. First, Design DNA, which decides overall flow of design concept of street furniture, is extracted through analyses of basic concepts of space design. Next, by applying 3V Design Process, alternatives of the concept generation are suggested through methods of storytelling and design language under the two approach methods of verbalization stage and visualization stage. Also its methods were explored through suggestion of designs by developing each idea of the respective concepts into specific design vocabulary.

Deep comprehension of basic mathematical notions and concepts is a basic condition of a successful teaching. Some elements of algebraic thinking belong to the elementary school mathematics. The question "What stays the same and what changes?" link arithmetic problems with algebraic conception of variable. We have studied beliefs and comprehensions of future elementary school mathematics teachers on early algebra. Pre-service teachers from three academic pedagogical colleges deal with mathematical problems from the pre-algebra point of view, with the emphasis on changes and invariants. The idea is that the intensive use of non-formal algebra may help learners to construct a better understanding of fundamental ideas of arithmetic on the strong basis of algebraic thinking. In this article the study concerning arithmetic series is described. Considerable number of pre-service teachers moved from formulas to deep comprehension of the subject. Additionally, there are indications of ability to apply the conception of change and invariance in other mathematical and didactical contexts.

This study discusses the nature of data-interpretation process in the perspective of modern hermeneutics and explores its methodological implications for qualitative research on the life of children. Discussions center around the basic concepts of modern hermeneutics, such as the conceptual distinctions between understanding and explanation, the intersubjective reality constituted between the child's horizon and the researcher's, the concept of the hermeneutics circle and the importance of the openness of language in understanding children's lifeworld. The conclusions are made as follows: First, the concept of "understanding", which is the basic concern of qualitative research on children, has a much different meaning from that of "explanation" in quantitative research. The task of understanding lies in interpreting the lived meaning in context as experienced by children in all its complexity. Second the researcher's subjectivity in the interpretation process has a dual function in that it can produce a faulty hermeneutics circle and yet it provides the researcher with the strong momentum to open up her understanding towards a deeper and wider level. Third, the reliability and the validity of qualitative research should be discussed within the interpretation process itself in that interpretation in qualitative research is guided basically by the researcher's internal dialectic: between data (text) and her subjectivity. Lastly, the language in interpretive research should be open and free in terms of style in order to present a fuller and richer description of children's lifeworld and the delicate textures of their lived meanings.

There is a growing global interest in food choices that could affect health. Consumer food choices are dictated by numerous factors such as attitudes, beliefs, desires and preferences stemming from psychological and physiological attributes. The present study aimed to understand consumers' internal perceptions about cream soup, cream sauce, and tomato sauce using ZMET (Zaltman's Metaphor Elicitation Technique). The 9 step ZMET interview process was conducted for a sample of 36 consumers (12 consumers for each sauce). A content analysis of the survey results was carried out. From this, 56 concepts of cream soup were derived, and 15 constructs that met with the agreement of more than one-third of the total sample consumers were extracted. These 15 constructs included 'Soft', 'Recollection', 'Familiar', 'Warm', 'Comfortable', etc. Similarly, for cream sauce, 67 concepts and 20 constructs 'Silky', 'Warm', 'Restaurant', 'Family', 'Memory', etc. were deduced. A total of 66 concepts and 20 constructs for tomato sauce 'Sourness', 'Sauce Bottle', 'Pleasant', 'Ingredient', 'Cooking', etc. were derived. The analysis of consumers' consensus maps through this study provides a deep and useful understanding of consumers and their latent needs. Also, the results of this study indicate that exploring consumers' internal perceptions is critical to understanding their healthy food choices. This can be used as basic data for formulating marketing strategies.

This study develops a t-shirt design that align bones and balance muscles in order to maintain proper posture using the basic concepts of symmetry. First, theoretical and 3D design studies, existing literature on proper and improper posture, and the basic concepts of symmetry are studied to create the design. Next, the 3D design process applies bilateral, rotational, and scaling symmetries to design the inner lines from the basic application of symmetry. A two-stage design process is used, whereby the strain map and pressure points are analyzed using the CLO virtual clothing software, and the most effective design is determined through virtual testing. The results show that the Y+)( and X+― design, which combines the position and type of inner lines, is the most effective for posture correction and maintenance. Overall, this study helps create a theoretical and practical basis for exploring and understanding basic lines appropriate for the human body, and subsequently, for developing various products that maintain posture more accurately and precisely.

This study examined the contents of 'Adolescent's Consumption Life' unit in 12 Technology Home Economics textbooks used in the 2009 revised curriculum to analyze the contents of school consumer education. The main summary of this study is as follows: First, the contents of consumer education in the unit of 'Adolescent's Consumption Life' consisted of five criteria including the understanding of adolescent consumer, consumer's right and responsibility, reasonable purchase, resolution to consumer problems, and the formation of new consumption culture. Second, significant differences were found in the contents of consumer education among textbooks because basic concepts have been not been clearly defined yet. Third, essential content was either omitted or hard to understand. Thus, some contents elaborations were inappropriate for students' level. Fourth, there were some limitations in drawing interest and attention from learners and developing dispute resolution competence, since the textbooks mainly comprised the theory-oriented contents of consumer education. Fifth, cautious consideration needs to be taken with regards to clear understanding of basic concepts and systematic and consistent contents composition for coherent and organized school consumer education. These research findings are anticipated to provide basic information of Technology Home Economics textbooks to teachers, and will be utilized as basic data in organizing textbook contents or developing efficient teaching-learning programs for consumer education.
