융합이라는 시대의 흐름과 더불어 상상력과 창조성에 기반을 둔 디자인·공예의 본질적 속성의 효과적 결합을 위해서는 학문적, 방법적 측면에서 다양한 시도가 필요하다. 본 연구는 2020년 2학기에 실행된 국민대학교 팀팀Class의 디자인·공예 융합 교육 프로그램의 운영 사례를 분석하는 것이다. 이를 위해 기존 문헌연구를 통한 디자인·공예 융합 교육 관련 중요 항목을 5가지(대상, 방법, 운영, 공간, 소통)로 구분해 분석하였다. 이를 통해 디자인·공예 융합 교육 프로그램에 대한 경험과 문제점, 그리고 향후 디자인·공예 융합 교육 프로그램의 운영에 적용 가능한 해결방안 제시에 본 연구의 목적이 있다. 본 연구에서는 국민대학교 팀팀Class 디자인·공예 융합 교육 프로그램으로 사례연구 대상을 한정하였으나 향후 지속적인 연구를 통해 향후 다가올 코로나(COVID-19) 이후 시대의 새로운 환경에 적용 가능한 디자인·공예 융합 교육 프로그램을 위해 후속 연구가 진행되어야 할 것이다.

The studio furniture movement that expanded in the United States after the Second World War was truly American creation representing highly sophisticated individualism versus industrial anonymity. The studio furniture movement can be traced back to the 1930s in terms of its influences and emergences. Based on the ideals of Arts and Crafts movements from the earlier decades, studio furniture movement emerged in the 1950s in reaction to Bauhaus inspired industrially produced furniture. Studio furniture has represented an alternative for people who wanted individual objects in their homes rather than industrially produced products. Opposed to plastics and industrial materials, artists in studio furniture mainly focused on one natural material, emphasizing its singular beauty. There were significant roles and influences of craft education along with Scandinavian influences in terms of spreading out the movement. A historical examination of furniture from the 1930s until the 1960s illustrates how this significant movement began in the mid-century.

Purpose: To investigate difference in health status by social classes in Korea through second analysis the 1999 Social Statistic Survey raw data performed by National Statistic Office. Method: 52,100 subjects were 20-64 years old and students were excluded. Health status was measured self-rated health and disease prevalence past 2 weeks. Social classes were classified 5 categories by occupations and working status and 1 category by unemployment. Result: Unemployed people reported the worst self-rated health on average, the lower social classes, the worse self-rated health and higher disease prevalence. Health inequality still existed between social classes after adjusting sex, age, and education level. Conclusion: A certain strategy for improving unemployed people's health and people who are working in craft, simple manual labor, agriculture, fishery, and forestry.

This study explored the characteristics of contemporary furniture called New Design furniture design in terms of aesthetics of communication in the postmodern era. Qualitative conceptural analysis as the principal methodology was used to explore the characteristics of New Design furniture, which is accessible to the broadest possible public. Thereby, the communicative elements of symbol, metaphor, narrative, animation, imagination, humor, and/or wit expressed in New Design furniture were analyzed according to the designers'concept and work. As a result the postmodern aesthetics of communication made New Design furniture accessible to the largest number of People through cultural considerations in New Design furniture as it influences designers 'concept and work. However, it showed problems of New Design furniture in connection with postmodern aesthetics affecting mass production. Therefore, the designers have begun rethinking, redefining, and redesigning their furniture aesthetically, functionally, economically, and ecologically.

The purpose of this study through ethnographic inquiry is to describe how an elementary teacher teaches mathematics with understanding. The ways that teachers'beliefs affect instructional activities, what means understanding from the view of cognitive psychology, and ethnographic research tradition were reviewed to anchor theoretical background of this study. A third-grade teacher and his 45 students were selected in order to capture vivid and thick descriptions of the teaching and learning activities of mathematics. Three major sources of data, that is, participant-observation with video taping, formal and informal interviews with the teacher and his students, and a variety of official documents were collected. These data were analyzed through two phases: data analysis in the field and after the fieldwork. According to data analysis, ‘teaching mathematics with understanding’ was identified as the teachers central belief of teaching mathematics. In order to implement his belief in teaching practices, the teacher made use of three strategies: ⑴ valuing individual student's own way of understanding, ⑵ bring students' everyday experiences into mathematics classroom, and ⑶ lesson objectivies stated by students. It is suggested for future research that concrete and specific norms of mathematics classroom for the improvement of mathematics understanding are needed to be identified and that experienced and skillful teachers' practical knowledge should be incorporated with theories of teaching mathematics and necessarily paid more attention by mathematics educators.

This paper aims to present colour theories and show how they can be used to explain consumer's preferences of some products over others. It will, furthermore, attempt to link these theories to the design industry and look at how colour associations determine product success. Due to associative learning and personal preference, the colours of objects can cause consumers to either favour or dislike products over those with identical functions and efficiency. Age and gender affect the preferred colour choices of the individual, making some products more popular to particular groups of potential consumers. Designers can utilise colour theories to ensure that they use the most appropriate colour schemes to maximise and appeal to their targeted market successfully. A survey was conducted with 100 participants. It demonstrates the associative links between colours, emotions and product categories. It can be shown that the colour of an object can contribute to its success or failure in the market based on a number of different criteria. The design must use colour confidently to evoke certain emotions or connotations and must be carried out appropriately. The designer also has to consider whom it is that be viewing it and making the decision of preference.

The golden ratio is a mysterious number that surprisingly appears in science, physics, mathematics, as well as in nature. The number 1.618 seems to be a universal constant, and crops up whenever the subject is of beauty or elegance. Beautiful flowers and sea shells and also attractive people have a common number and that is 1.618 or $\varphi$ (phi). This paper does a study into the story of phi, and describes how the golden ratio is derived. Artists, architects and designers have employed the ratio into dimensioning their works of art to achieve visual appeal. Examples such as the Greek Parthenon of the Acropolis and paintings such as the Last Supper all use this magic number. An investigation was conducted among 50 people to test if looking at golden proportioning was actually appealing, or if it was just a type among overzealous enthusiasts. The results show that the golden ratio may actually be of some use.

Technophobia is described as the 'abnormal fear or anxiety about the effects of advanced technology', affecting one third of the population, causing health problems and the inability to work efficiently. The development of the mobile phone, both in its design process and its following socioeconomic success, has a prominent effect on our society in general; this point will be explicated in this paper. The negative effects of these developments have also been assessed with questionnaire-based interviews, focus groups and media analysis in order to focus on those who are most susceptible to the effects of technophobia, to discover the possible causes and to develop a solution for overcoming the phobia. The findings of the literature review and empirical research have been debated; the results proved inconclusive. All age and sex and groups displayed levels of anxiety around technology. Therefore, designers cannot afford to abandon these individuals in the future, and attention should be directed into inclusive product design. Therefore, various solutions have been suggested for support for these sufferers, such as tuition and bespoke, 'built to specification' mobile phones.
