Currently science and technology are changing so fast and college mathematics becomes more and more important. But the downturn of freshmen`s scholastic performance has been intensified and this phenomenon leads to serious problems in managing college curriculums. During the recent years at a middle level engineering college, many freshmen had a lot of difficulties in their mathematics courses. In consequence, many of them had hard time to survive at their major curriculums. In this point of view, we analyse the situation of mathematical scholastic ability among engineering majored freshmen through the research on the actual state of mathematical background, mathematical scholastic ability test, college mathematics scores, and scholastic aptitude test scores. We study the relation between the mathematics score of scholastic aptitude test for the college entrance and mathematical scholastic ability of freshmen of a middle level engineering college. From this study we conclude that the essential reasons for the above situations are the curriculum of middle school mathematics and the system of scholastic aptitude test and the entrance examination of university. In order for improving mathematical accomplishment. we give suggestions such as a learning ability improvement program in .mathematics.

The purpose of this study is to examine the possibility of anthocyanin pigments of black soybeans, which is natural hair dye and free from skin irritation and environmental pollution, as hair dye to make up for the limitations of natural hair dye such as simple color and unscientific process of hair dyeing. In order to achieve this purpose, anthocyanin concentration was analyzed by measuring absorbency from anthocyanin 540 nm of black soybeans and color changes were observed according to changes in temperature and pH through color measurement. Unmordanted hair dyeing was increased in dye intake (K/S) with increased dyeing temperature (20~80℃) and hair color was changed from red to purple. Increased dyeing hours were associated with decreased lightness (L), and as temperature became higher, the b* (chromaticity coordinate [±b] in the yellow-blue axis in CIE LAB) level got close to 0. It suggested that changes in lightness and a* were one of determinants of dyeing hair color. In unmordanted hair dyeing, it was expected that dye intake according to pH and color measurement effect would be the same as anthocyanin pigments, but color changes in hair dye in alkalinity were not connected with changes in hair color. With increased pH, a* value proceeded from +(red) to - (green) or a color meter was reacted to yellow of original bleached hair and Munsell`s H was changed into 6.169YR → 2.771Y → 2.578Y → 1.365Y in alkalinity (especially pH 9~13). In the alkalic status, black brown or a black green was shown because of reddish brown deposits and discolored original color of anthocyanin mordant. It brought about poor dye intake and dyeing or mordanting effects were lost. It suggested that anthocyanin mordants were specially sensitive to pH and dye intake was rapidly decreased with increased pH.

공과대학 신입생들의 수학에 대한 인식변화에 따른 대학수학 교육방향 연구

이정례 ( Jung Rye Lee ) 한국수학교육학회 2015 수학교육논문집 Vol.29 No.3

본 연구에서는 중위권 공과대학 신입생들의 수학에 대한 인식변화에 따른 대학수학의 교육방향을 연구하기 위하여 A대학교 공과대학 2011년과 2015년 신입생들을 대상으로 수학기초학력평가와 수학에 대한 인식 및 대학수학에 대한 설문을 실시하였고, 수학에 대한 인식변화를 고등학교 계열별, 대학수학능력시험 수학영역 응시유형별, 수학기초학력평가 성적별로 분석하였다. 연구 결과, A대학교 공과대학 신입생들은 수학기초학력이 부족한 것으로 나타났고, 2015년 신입생들은 2011년에 비해 자신이 느끼는 수학실력 수준이 향상되었고 대학수학 수업에서 더 노력하겠다고 답했다. 한편 2011년과 2015년 신입생 대부분이 대학수학은 전공을 위한 기초과목으로 인식하였고, 수업은 고등학교 중급수준에서 시작하는 것과 교수가 이론설명 및 문제풀이도 해주는 수업방식을 선호했다. 본 연구 결과를 바탕으로 효율적인 대학수학 수업을 위해서는 교수 학습에서 수학기초학력의 향상에 초점을 두고 학생들 스스로 문제를 해결하는 학습태도를 강조해야 함을 제언하였다. In order to suggest desirable management of college mathematics for freshmen in middle level engineering college, we analyse the change of mathematics recognition between 2011 year and 2015 year freshmen who took college scholastic ability test which are based on the national mathematics curriculum 7th and 7th revision, respectively. In A university, 2011 year and 2015 year engineering freshmen were taken basic mathematical ability test and given the survey for the recognition of mathematics and college mathematics. Research results are as follows: First of all, middle level engineering freshmen were poor at basic mathematical ability. The change of mathematics recognition appeared in the level of mathematics ability and the effort for college mathematics class. Moreover middle level engineering freshmen recognize college mathematics as a basic subject for engineering and hope teacher-directed learning in college mathematics class. For the success of college mathematics in engineering college, this study suggests basic mathematical ability test and the survey for the recognition of mathematics and college mathematics. We also suggest that college mathematics class must be focused on basic mathematical ability improvement and self-directed learning. * ZDM Classification : D35, D34 *

이경희 ( Gyeoung Hee Lee ),이정례 ( Jung Rye Lee ) 한국수학교육학회 2015 수학교육논문집 Vol.29 No.3

본 연구는 대학 신입생의 고등학교 재학 시 선행학습경험, 내신등급, 수능수리영역등급과 대학에서의 대학수학교과성적, 대학학업성취도(GPA) 간의 관계를 보았다. 이를 통해, 고등학교 재학 시의 수학교과 학업능력이 대학 신입생의 대학수학교과성적에 어느 정도 영향을 미치는지 분석하고자 하였다. 연구의 목적을 위해, A대학교 2014학년 1학기에 개설된 ‘기초미적분학’을 수강한 이과대학 및 공과대학 신입생 193명을 대상으로 설문을 실시하고 성적 등 관련 자료를 활용하였다. 이들 자료는 기술통계, 상관분석, 차이검정, 일원변량분석(ANOVA), 사후검정 및 회귀분석을 실시하였다. 연구결과, 첫째, 연구 대상 대학생의 90% 이상이 고등학교 재학 시 수학교과 선행학습을 한 것으로 나타났으며, 둘째, 선행학습의 효과성에 대한 인식은 필요성 인식보다 유의미하게 낮게 나타났다. 셋째, 대학수학교과성적과 대학학업성취도 간에는 높은 정적 상관관계가 있었으나, 내신등급과 대학학업성취도 간 및 수능수리영역등급과 대학 수학교과성적 간에는 미미한 수준의 상관관계만 있었다. 넷째, 고교성적(내신등급, 수능수리영역등급), 선행학습노력, 선행학습만족도, 선행학습필요성이 대학수학학업성취도에 미치는 영향력은 미미한 수준이었다. 연구결과를 바탕으로, 대학수학교과의 학업성취도를 높이기 위한 방안을 제언하였다. This study examines the relationship between prior learning experience, the high school records, mathematics grade in the KSAT(Korean Scholastic Aptitude Test) and mathematics achievement, GPA(grade point average) of college freshmen. It analyses how much mathematics capacities in the time of high school affect mathematics achievement of college freshmen. This study surveyed 193 freshmen, attending in a college of science and engineering, taking the ‘basic differential and integral calculus’ lecture, which was opened for the first semester of 2014 in the A university. The data processing was fulfilled by means of technical statistics, correlation analysis, difference test, ANOVA, ex post facto test, and regression analysis. The outcomes of this survey are followings: Firstly, over 90 percent of college freshmen underwent prior learning of mathematics when they attended high school. Secondly, their perception of effectiveness for prior learning is founded to be meaningfully lower than their perception of its needfulness. Thirdly, while there is higher positive correlation between mathematics achievement and GPA in the college, there is little correlation between high school records and GPA in the college. Also, there is little correlation between mathematics grade in the KSAT and mathematics achievement in the college. Fourthly, the accomplishments in the high school(The high school records, mathematics grade in the KSAT) and the efforts, satisfaction, necessity, etc. for prior learning had little effect on academic achievement in college mathematics. Based on these results, this study makes some suggestions for developing academical achievement in college mathematics.

앵포르멜 회화의 조형적 특성을 모티브로한 헤어아트분석

이재숙(Jae-Sook Lee),이정례(Jung-Rye Lee) 한국인체미용예술학회 2020 한국인체미용예술학회지 Vol.21 No.3

In modern capitalism, logical and rational thinking and philosophical thought are emphasized. Therefore, modern people ask for an ordered system under strict rules and regulations. Since World War II, European abstract expressionism, ‘art informel’, developed in search of a worldly and fundamental meaning against the inhumane aspects brought about by a geometric world, which emphasized strict and balanced order through reason and rationality. The formative characteristics and colors of such art informel painting patterns can be the origin of new ideations in hair art. Therefore, this study attempted to escape from the traditional order of hair art using formative characteristics after the analysis of art informel artists’ works and liberate human emotions by altering situations. To this end, this study analyzed the formative characteristics of art informel paintings and created formative hair artworks using them as a motive. It is anticipated that there would be further studies on art informel and creative hairstyles through broad and in-depth analysis.

이경희 ( Gyeoung Hee Lee ),이정례 ( Jung Rye Lee ) 한국수학교육학회 2015 수학교육논문집 Vol.29 No.4

최근 우리나라 수학교육에 있어서 정의적 영역이 강조되고 있는데, 특히 수학 학업성취도와 관련하여 수학적 성향이 중요시되고 있다. 한편 우리나라 교육과정은 자주 바뀌었는데, 7차 교육과정에서 인문계는 미적분을 배우지 않았으나2007 개정 교육과정에서는 인문계도 미적분을 배웠다. 본 연구에서는 D대학교 공과대학에 입학한 7차 교육과정 세대인 2011년과 2007 개정 교육과정 세대인 2015년 신입생들을 대상으로 수학적 성향의 변화를 분석하였다. 이를 위하여 수학적 성향 검사를 실시하였고, 학생들의 수학적 배경 및 대학수학에 대한 학습목표를 설문하였으며 수학기초학력을 평가하여 고등학교 계열별, 대학수학능력시험 수학 영역 유형별, 대학수학 학습목표별, 수학기초학력별로 2011년과 2015년 수학적 성향의 각 요인의 변화를 분석하였다. 그 결과, 2011년과 2015년 학생들 사이에는 자신감, 융통성, 의지력, 호기심, 가치, 심미성 등 수학적 성향에서 많은 차이를 보였다. In order to examine the change in mathematical inclinationn of middle level engineering college freshmen, we analyse the change of mathematical inclination between 2011 year and 2015 year freshmen who took college scholastic ability test which are based on the national mathematics curriculum 7th and 7th revision, respectively. In medium-sized D university, 2011 year and 2015 year engineering freshmen were taken the test for mathematical inclination, the survey for mathematical background and the recognition of college mathematics and basic mathematical ability test. The outcomes of this survey are followings: Firstly, between 2011 year and 2015 year freshmen, the mean of confidence and flexibility are same, but the 2015``s mean of willpower, curiosity, value and esthetics are greater than 2011``s. Secondly, in the mean of flexibility, willpower and curiosity, natural science``s mean is greater than humanity``s. Thirdly, the mean of mathematical inclination``s factors is depend on college mathematics goal. Fourthly, there is little correlation between mathematical basic ability and mathematical inclination. Moreover for 2011 year and 2015 year freshmen, the mean of mathematical inclination``s factors except value is proportional to mathematical basic ability. For the success of college mathematics in engineering college, this study suggests that high school mathematics curriculum and college scholastic ability test must contain calculus. We also suggest that college mathematics class must be focused on mathematical inclination improvement.

Insulin therapy is indicated in the treatment of gestational diabetic women and overt diabetic pregnant women for hyperglycemia after failure to respond to the diets and exercise regimens. The insulin is administered to mimic normal pancreatic function. The normal pancreas secretes 50% of the total daily insulin as mealtime boluses. This delivery may be mimicked by four-injection-per-day of combination of NPH and regular insulin (RI). Hypoglycemia is a well-recognized complication of intensive insulin therapy in patients with Type Ⅱ diabetes. Recently, it has been reported that insulin-lispro, an analogue of regular human insulin with a peak insulin action achieved with a 1 hour after injection improves postprandial glucose concentration in non-pregnant diabetic patients. Treatment of gestational or diabetic pregnant women with NPH and insulin-lispro has significantly lower postprandial glucose levels without an increase in hypoglycemic events. Here, we report 2 cases of hyperglycemic control with four times daily administration of NPH & insulin-lispro on diabetes in pregnancy, with brief reviews.
