  • In this paper we survey on the geometric development in the history of Joseon mathematics. We have relatively many research papers on the history of equations in Joseon but the history of geometry is limited to that of trigonometry (gugosul). We survey on the results on the whole geometry including the introduction of western geometry in Joseon. Joseon mathematics developed differently during several different periods. We investigate how geometric theories developed during those periods and the meaning behind them. We do not claim that our survey is anywhere close to a complete one. This is rather a preliminary attempt to collect research results to plan our research following those of our predecessors.

  • Objectives: We evaluated the reliability of the possible covariates of the baseline survey data collected for the Epidemiological Investigation on Cancer Risk Among Residents Who Reside Near the Nuclear Power Plants in Korea. Methods: Follow-up surveys were conducted for 477 participants of the cohort at less than 1 year after the initial survey. The mean interval between the initial and follow-up surveys was 282.5 days. Possible covariates were identified by analyzing the correlations with the exposure variable and associations with the outcome variables for all the variables. Logistic regression analysis with stepwise selection was further conducted among the possible covariates to select variables that have covariance with other variables. We considered that these variables can be representing other variables. Seven variables for the males and 3 variables for the females, which had covariance with other possible covariates, were selected as representative variables. The Kappa index of each variable was calculated. Results: For the males, the Kappa indexes were as follow; family history of cancer was 0.64, family history of liver diseases in parents and siblings was 0.56, family history of hypertension in parents and siblings was 0.51, family history of liver diseases was 0.50, family history of hypertension was 0.44, a history of chronic liver diseases was 0.53 and history of pulmonary tuberculosis was 0.36. For females, the Kappa indexes were as follow; family history of cancer was 0.58, family history of hypertension in parents and siblings was 0.56 and family history of hypertension was 0.47. Conclusions: Most of the possible covariates showed good to moderate agreement.

  • This survey is the first part of the history of science of Song and Yuan dynasties and covers the period starting from Song to Jin. The major science in the Song period consists of calendrical astronomy, mathematics and medicine, and mathematics is also related to water supply technology. In this survey we follow Yabuuchi's work on the history of science of Song and Yuan period and Du Shiran's work on the history of science of China. We will try first to see how academic science flourished in the Northern Song, what caused the public science to prevail in the Southern Song, and then how the academic trend continued in Jin. We will continue to cover the Jin-Yuan period in the ensuing survey.

  • Purpose: To provide baseline data for prevention and education of diabetic foot in Korea. Materials and Methods: 216 diabetic patients are included in this survey. The average age is 58.64 year old with average 9.92 years of diabetes mellitus periods. Among them, 41% used insulin injection, 42% oral medication, 14% both and 3% diet were used for their blood sugar control. The diabetic foot survey was done. Results: The survey of patients symptom and disease of their feet results: 49% had sensory decrease in their feet. Associated disease in foot were callus(15%), heel pain(10%), bunion(4%), toe deformity(2%), Tinea pedis were 9%, tingle sensation were 17%, and swelling on feet were 2%, The survey of patients privious history of foot problems are: 8% had previous operation history on their feet and 17% had history of infection on their feet, 23% had bullae history, The survey of patients prevention and education are: Those who have had more than one diabetic foot education were 45.7%, and among them 24% had routine regular foot check up. Only 5% wear special diabetic shoe and 3% had custom orthotics. Conclusion: Interests to diabetic foot care is increasing in diabetic patients in Korea. However still we need more education, and efforts for prevention. Special education and diabetic shoe is still low, The survey data could be good baseline for diabetic prevention and education.

  • This project was carried out under the assumption that applying a science history program to a teaching-learning process would lead to students' increased interest in science and increase the development of their scientific process skills. The project aimed at designing an effective science history program which would help to improve students' scientific process skills, to enhance their interest in learning science, and to maintain their inquiry learning abilities. The survey for the activity objectives was produced by the authors. The test items used for testing students' scientific attitude and scientific process skills were created by Korea National University of Education. The survey about scientific perception indicated that there was a meaningful difference of p=0.005 before and after implementing this program. The survey about scientific interest shows that students became interested in science, science-learning and science-related activities after participating in the science history program. Students' scientific process sills increased by 9% after the program was implemented in the subjects' classes. This indicates that the science history program was effective in improving students' science scientific process skills. Since this project, which targeted 8th grade science education activities, has proven to be effective, developing other programs suitable for younger and older students seems promising, too.

  • 본 연구는 국내 고등학교 역사교사의 기록물 이용행태를 파악하기 위한 것이다. 이를 위하여 고등학교 역사교사를 대상으로 3번의 사전인터뷰를 진행하였으며, 2개 지역 역사교사 모임 회원 50명을 대상으로 설문조사를 실시하였다. 설문조사는 기록물과 기록관에 대한 인식, 기록물 이용현황, 기록물 탐색경로, 기록물 이용시 장애요인 및 서비스 방안 등 크게 4개 분야에 걸쳐 이루어졌다. 조사결과 설문에 참여한 역사교사들은 주로 학생들의 역사적 이해력이나 자료에 대한 해석 능력을 높이기 위하여 수업에서 기록물을 어느 정도 사용하고 있는 것으로 나타났다. 그러나 수업일정이나 교사의 시간 부족 등은 기록물 이용에 장애가 되는 요인으로 나타났다. 설문참여자들은 향후 수업에서 기록물이 활발히 이용되기 위해서는 기록물을 통합적으로 검색할 수 있는 DB가 구축되어야 하며, 기록물에 대한 해석 등이 부여된 가공된 형태의 자료집 등이 필요하다고 보았다.

  • In this paper, I will divide the history of mathematics into four development stages. These are based on significant developments of mathematical concepts or the creation of new fields of mathematics. Then, I will survey the history stages through a study of the characteristic method of research and the most important concepts from each period.

  • This survey is the second part of the history of science of Song and Yuan dynasties and will covers the period from Jin to Yuan. Following the first part, we look at the calendrical astronomy, mathematics and medicine. In this survey we again follow Yabuuchi's work on the history of science of Song and Yuan period and Du Shiran's work on the history of science of China. We start from the sciences and mathematics of Jin which inherited those of Northern Song and see how they influenced the whole China including Yuan and Southern Song. As a conclusion the tendency to practical usages in the Southern Song as well as the suppression of Han people in Yuan prevented developments of theoretical sciences in Yuan and Ming later.
