Recently, there have been many changes in researches of mathematics education. There is a growing number of researchers who are interested in empirical researches. According to the these changes, there is also an emphasis on methodology of mathematics education. This means that many researchers try to conduct an research using scientific approach. Therefore, new types of research developing mathematics courses recently has evolved as follows: teaching experiment, hypothetical loaming trajectory, design science, developmental research. The aim of this study is to reflect on developmental research in RME and to induce desirable directions for developing our mathematics courses. In order to attain these purposes, the present paper reflects the philosophy of RME, aim, procedure, data collection, data analysis, and justification of developmental research with illustrating a exemplar Based on these reflections, it is discussed that it needs to construct the mathematics curriculum connecting theory and practice in mathematics education, to report the process of developing mathematics courses faithfully, and to develop real mathematics courses after conducting basic developmental researches in order to take scientific app- roaches for developing mathematics courses.

The present study aimed at investigating how Korean housekeeper in midlife revaluate their lives. For this purpose, 14 housekeepers whose youngest child was at least older than high school students were interviewed in a semi-structured retrospective method. The interview was focused on relational, psychological, and economical aspects of the participants before and after marriage each. The interview usually continued one and a half to two hours. The phenomenological method describing personal meaning of experiences was referred to for data analyses by transforming retrospective life story of participants into key meaningful units. According to main retrospective contents of each stage of development, the participants' childhood and adolescence was characterized by familial circumstances, formation of personality and value, and career choice. Main themes of their early adulthood were spouse selection and marriage, marital adaptation, and family relationships. Their midlife focused on children, economic and emotional stability, family relationships, acceptance of their spouse and themselves, and health and religion. Life styles of the participants were analyzed in terms of turning events, meanings of current life, and cumulative effects of life events. These findings were discussed in terms of developmental pattern in relation to the established theory of development.

한국의 기후학 연구성과는 1958년 발표된 이후 약간의 기복은 있었으나 꾸준히 발 전하여 왔다. 연구성과를 하부 분야별로 보면 기후학 일반(43.5%)이 가장 많았고, 종관기후 학(34.7%), 기후변화(13.0%) 그리고 응용기후학(8.8%)으로 구성되어 있으나 근래에는 응용 기후학 분야에 대한 연구가 서서히 증가하고 있다. 1970년대 이전에는 주로 지상 기후요소 간의 기상자료를 사용하여 상관관계 출현빈도.시계열분석 등으로 전국 규모의 기후특성을 규명한 데 반하여 최근에는 시계열분석과 더불어 군집.주성분.인자분석 등 다변량 분석기 법 등의 통계기법이 많이 활용되고 있다. 초기에는 지상기상자료를 주로 연구에 사용하였는 데 점차 고층기상자료와 인공위성자료를 활용하면서 국지기후 연구와 더불어 기후예측 모델 의 구축단계까지 발달하였다. 그러나 한국기후학이 당면한 문제는 인적자원의 절대적인 빈 곤과 더불어 인접분야에 비하여 연구환경이 열악한 것이다. 즉, 대학에서는 비전공자에 의한 기후학 교육이 빈번하고, 국지기후 연구의 경우는 실측을 요하기도 하는데 자료의 생성 및 분석에 필요한 장비가 절대적으로 부족하다. 따라서 한국의 기후학의 발전을 도모하려면 기 후학자의 배출이 급선무이고, 기후학자는 물론, 대학 및 연구소간의 연구 및 자료 교류 등의 상호협조가 요청된다.

The development of Korean urban geography can be divided into several stages including initial stage, transition stage, and maturation stage. If this trend persists, it can be expected that it would turn into the matured stage. This paper intended to recall the research trends from 1960 to 2012, focusing on 686 papers and 177 books published during the last 62 years, and investigated by research areas, study regions, methodologies, and journals in relation to urban geography. Although increasing number of urban geographers has made mutual relationship more complex and diverse, no signs of school formation have yet been seen in Korean urban geography. Large portions of papers have concerned about Seoul Metropolitan Region for their study regions. There have been diversified trends of oversea studies away from the US cities to other cities in various countries. Also, quantitative studies have been increasing their weight since the 2000s. Moreover, articles on the Journal of the Korean Urban Geographical Society have been far surpassed in its number.

This study explored how early stage entrepreneurs think about key success factors of startup and its impact factors. Previous research on key success factors of startup focused on high technology industry or explored retrospectively main reason of their startup success. However, preparatory entrepreneur who lacks career and social experience has different point of view of startup success, because of their situation which they overcome various problem of entrepreneurial process. This research surveyed key success factors and impact factors of entrepreneurial success based on 905 preparatory entrepreneur. We witnessed that preparatory entrepreneur recognizes various key success factors and found different key success factors according to the attribute of preparatory entrepreneur. We found that man, team startup and non technology related startup in 20s age emphasized procuring superior manpower. But solitary startup and previous career related busienss and long preparation term in 30s age recognized importantly about the entrepreneur's ability. Also, preparatory entrepreneur who considered importantly sales promotion and thorough preparation has different attribute. We can find a unique point that Funding capability was not significant attribute. Finally we suggested implication and further research agenda to foster young entrepreneur based on major findings.

The epidemic of COVID19 caused a big change in design collaboration, which has been conducting using face-to-face interaction. Designers actively used video conferencing and online document tools in situations where face-to-face meetings were difficult, and this gave them an opportunity to experience that non-face-to-face collaboration can be more effective in a specific design process. In this regard, this study attempted to find out which activities during the design process are more compelling in face-to-face collaboration or non-face-to-face collaboration. To do this, three user experience design projects conducted after the COVID19 epidemic were analyzed through a retrospective interview method. As a result, during four design stages, 'Discover, Define, Develop, Deliver', face-to-face collaboration is necessary for the areas that require creative problem solving through active interaction. In contrast, non-face-to-face collaboration is preferred and more effective when designers need their own space and proceed their design work. In addition, the aspects of design tools supporting non-face-to-face collaboration were also illustrated. Findings discovered through this study are expected to contribute to research on the design process later.
