초행길 인생인 우리들이 시행착오를 줄이려면, 인류가 이룩한 인생살이의 교훈과 노하우를 미리미리 교육을 통해 깨닫는 것이 필요하다. 교육현장에서 미시적 탐구 위주의 수학교육 연구영역을 삶에 관계되는 영역까지 확장하여, 인생살이를 효율적으로 통찰하고자 한다. 본 연구는 인생살이를 살피는 방법들을 크게 네 가지로 분류하고, 인생살이 통찰에 필요한 수학적 모델을 경험 가능한 일상영역에서 찾을 수 있도록 설계하였다. 이렇게 만들어진 모델세계로 인생살이를 통찰하는 예를 통해, 수학적 모델링으로 인생살이를 통찰하는 방법을 새롭게 소개한다. It is necessary to realize in advance the lessons and knowhow about how to live, which humankind have developed, through learning to decrease the number of trial and error in our first trip to life. The big problem that present mathematical education is faced with is just only to place much importance on doing microscopic research ignoring macroscopic perspective, which results in the ineffectiveness of mathematics for contributing to life. The purpose of present study is to examine the way of living, classify methods of gaining an insight into life using macroscopic perspective, and develop a life model which can suggest a way of gaining an insight into life from external perspective. Also, this study explores a way of building a creative mathematical model for effective insight about life.

Objectives: The purpose of this study was to assess excavator drivers in order to determine the proportion showing subjective symptoms of musculoskeletal disorders and to evaluate the association between the symptoms and characteristics of the subjects. Methods: A questionnaire survey was conducted to collect the information on participants’ age, average working hours per day, duration of career (years), work-related musculoskeletal symptoms, and more. The final dataset included 141 excavator drivers. Frequency and percentage were summarized and then the associations between the characteristics of the subjects and symptoms were evaluated as odds ratios (ORs) and 95% confidence intervals (CIs) using multiple logistic regression analysis. Results: Seventy-six percent of the currently reported musculoskeletal symptoms. Those who have musculoskeletal symptoms attributed their symptoms to unstable posture at work, mental stress or vibrations. There was a significant association between symptoms of musculoskeletal disorders and career of excavator drivers (P for trend=0.04). Conclusions: The results of this study suggest that the prevalence of musculoskeletal disorders may be high among excavator drivers and warrants well-designed studies on work-related disorders among excavator drivers.

대학교육에서 시행되는 강의평가가 절대점수 위주로 평가되고 있어, 그 문제점이 심각하다. 이 논문은 수학과 관련된 교과내용학, 교과교육학, 교양수학, 교양강좌에 대한 강의평가의 문제점을 실용교양강좌와 비교하면서 그 문제점을 찾고자 한다. 대학교육의 강의평가에서 특히 교양수학을 담당하는 교수들의 불이익이 상당하기에, 수학교육계에서 수학강좌에 대한 현 강의평가의 문제점을 본 사례연구를 통한 대내외에 알려 적절한 보정작업을 요구할 근거를 마련하고자 한다. This paper deals with disparities in course evaluation between general and major courses of mathematics education. We provide concrete evidences which verify the mismanagement of the evaluation system and can be an impetus to a more rational one. We indicate the direction to which professors of mathematics education should head. Also those statistics obtained from the author`s teaching of mathematics education and related subjects for twelve years are provided for the fact-finding of and improving the erroneous evaluation system.
