When function modeling with IDEF0 which is called as a standard methodology for CALS (FIPS 183), the initial work is to determine the purpose and viewpoint, and the next work is to generate a data list and an activity list. This work requires participant's discussion and agreements. The main problems for these working are a communication between participants and efficient discussion processing. Brainstorming is the most useful method for this work. The paper is for development for the modeling assistant tool to promote the business modeling. In this paper, we will introduce the tool which name is 'MindMapper' and 'Dyna-IDEF'. Mind-mapper is software for mind-map method that is used for creative thinking. Using this tool, we refine the result of the brainstorming about activity list and translate the result into the functional model of IDEF0 using Dyna-IDEF. The translated functional model is prototype model without ICOM arrows.

The purpose of this study was to delve into what type of expression mode of fashion design could suit the life style of digital nomads, as the appearance of nomadic life style was concurrent with people's modified way of thinking and sociocultural changes in today's digital society. It's basically meant to define the roles of fashion design, which was discussed as a way of improving the quality of life as a sort of 'culture,' and to suggest some of the right directions for fashion design in the future. The culture of today's digital era is marked by a pursuit of high mobility and high speed, and by nomadic disposition that is built on flexible thinking. The kind of design that lets people carry nomadic things with them and thereby improve their mobility can satisfy their needs for mobility, and body-friendly design that functions as a device of information in itself can meet their needs for mobility as well. The leading example of the latter is a wearable computer, and wearable scientific technology will be taken to another level, thanks to the advance in digital technology. In the future, that will be more accessible to people in general, and subminiature digital equipment will gain popularity in fashion industry as part of textiles and clothing or as an accessory. And specific kinds of design will be widespread, including variable design, multi-functional design and modular design. The first serves as a tool to protect the human body and to facilitate the adaptability of it to the given circumstances, and the second is characterized by a superb physical and psychological protectability. The third lets wearers bring design to completion at their own option, owing to an increase in the number of open-minded people and the development of interactive media. All these types of design could be called a wearer-friendly, human-oriented design that is specifically appropriate for the digital age. Wearers can actively be involved in design process as productive consumers, which is expected to help increase opener practices in fashion design sector.

With the development of cognitive science and environmental psychology, there have been growing researches and discussions on the relationship between the residential design preferences and personality types. MBTI personality types have been earning popular credibility. MBTI means Myers-Briggs Type Indicator. It is based on Carl Jung's theory of psychological type. This study is based on Myers-Briggs theory to explain residential furnishing preference and explores the relationship between the four bi-polar personality types-Extroversion/Introversion, Sensing/Intuition, Thinking/Perceiving and residential furnishing preference. These tests were conducted to two hundred and twelve adult residents who live in Seoul, Korea. These tests were analyzed several significances by Chi-Square with SPSS for windows software. (E) Extroverted residents prefer layouts for interaction with guests. (I) Introverted residents prefer centripetal layout around the bed. (S) Sensing residents prefer practical and functional layouts. (N) Intuitive residents prefer personal and conceiving layouts. (T) Thinking residents prefer for attribute of space. (F) Feeling residents for familiar conversation. (J) Judging residents prefer systematic and complete layouts. (P) Perceiving residents prefer adaptable and flexible layouts. In conclusion, personality types can have a determining role in preference of residential furnishing layouts. This study suggests that residential designers should take into account clients' personality types prefer effective designing and should provide a variety of alternatives reflecting clients' preferences. This will promote clients' pleasantness and satisfaction in dwelling at home.

This article provides how to implement the use of Realistic Mathematics Education (RME) in a teaching a function at a school to improve the equity based on the gender in students' mathematization for their mathematical thinking using technology. This study was planed to get research results using the mixed methodology with qualitative and quantitative methodologies. 120 middle school students participated in the study to bring us data about their mathematical achievement. Through the data analysis used by ANCOVA for the qualitative method, the students with the experiment of the mathematization based on technology excelled the other groups of students who were not provided with technology or both of them. Through the data analysis used by the constant comparative method for the qualitative data, the technology environment had helped the female students manipulate learning trends easily, strong construction on horizontal mathematization, depending on discussion with peers, and more reflexive thinking using a calculator. This means that teachers can put careful assignment on each category of mathematization regarding the gender. The study results in a lot of resources for teachers to use into their teaching mathematics for improving students' equity in interactive technology environment.
