2015 개정 교육과정을 반영한 대학 미적분학 교과에 대한 탐색

김윤아,김경미,Kim, Yun Ah,Kim, Kyung Mi 한국수학교육학회 2017 수학교육논문집 Vol.31 No.3

2015 개정 교육과정은 창의융합형 인재를 양성하기 위해 국가 사회적 요구를 학교교육과정에 반영한 문 이과 통합형 교육과정이다. 이러한 변화와 더불어 교육부에서는 2017년부터 대학교 4학년 때까지 전공을 변경할 수 있는 제도를 도입하였다. 따라서 각 대학에서는 2015 개정 교육과정을 이수한 학생들을 맞이하기 전에, 교육과정 및 제도 변화를 반영할 준비를 해야 한다. 대학은 신입생들이 수강하는 미적분학 교과목 운영과 교육내용을 준비할 때 2015 개정 교육과정 시행과 전공변경 시기 확대에 대한 대응방안을 연구할 필요가 있다. 한동대학교는 무전공무학부제로 1학년 때 전공을 결정하려는 신입생을 대상으로 수준별 미적분학 교과목은 운영하고 사전시험을 실시하여 신입생들에게 적합한 미적분학 분반을 배정하는 등 다양한 운영 방안을 모색해왔다. 이 사례는 2015 개정 교육과정의 기본 취지와 유사하므로 교육과정 개정 후 대학 미적분학 수업 운영 방안에 대한 시사점을 제시해줄 수 있다. 본 논문에서는, 최근 5년간 한동대학교 신입생 수학시험 결과와 학생들의 미적분학 교과 성적을 분석하여 상관관계를 도출하고, 한동대학교에서 운영하고 있는 미적분학 교과목 내용과 2015 개정 고등수학 교육과정을 비교하였다. 그 결과, 대학 전공계열에 적합한 미적분학 교과목을 5개 수준으로 구성하여 제안하였으며, 대학 미적분학 교과과정에 2015 개정 교육과정에서 부족한 구분구적법을 포함하여야 함을 찾을 수 있었다. The 2015 revised curriculum is an integrated curriculum that reflects national and societal needs to foster creative convergent talent in the school curriculum. Along with these changes, the Ministry of Education introduced a system to change the major from 2017 to the fourth year of university. Therefore, each university should prepare to reflect the curriculum and institutional change before welcoming students who have completed the 2015 revised curriculum. The university needs to study the countermeasures for implementing the 2015 revised curriculum and expanding the period of major change when preparing the curriculum and contents of the calculus courses that freshmen take. Handong University has been studying the operation methods of new students who want to decide their major at the first grade, such as operating calculus courses at various levels and allocating appropriate proportions of calculus for preliminary examinations. This case is similar to the basic purpose of the revised curriculum in 2015, so it can suggest implications for the operation of the university calculus class after the curriculum revision. In this paper, we have analyzed the results of the recent freshman mathematics test for the recent 5 years and the students' calculus grades and compared them with the contents of the calculus curriculum operated by Handong University and the 2015 revised higher mathematics curriculum. As a result, we proposed five classes of calculus suitable for college major and it was found that the calculus curriculum should include the missing quadratic method in the 2015 revised curriculum.

약물 수송체로 사용되는 리포솜은 동결 건조를 통하여 분말화 시키는 방법이 사용되어지고 있다. 리포솜 안정제로서 말토스는 동결건조된 리포솜 분말의 안정성을 향상시키고 약물 봉입률에 영향을 주는 것으로 알려져 왔다. 동결건조 전과 후의 리포솜 입자의 크기를 측정하므로서 리포솜의 안정성을 평가하였고 또한, 약물 봉입률은 모델 약물인 칼세인을 사용하여 조건에 따른 봉입양을 측정하였다. 리포솜 제조 후에 말토스를 첨가한 리포솜은 수화하는 과정에서 말토스를 첨가하여 제조한 리포솜보다 훨씬 더 안정한 것으로 확인되었다. 말토스를 첨가하지 않은 리포솜은 시간이 지남에 따라 입자의 크기가 커지는 반면, 리포솜 제조 후에 말토스를 첨가한 리포솜은 $4{\sim}37^{\circ}C$에서 30일 동안 안정하다. 또한, 말토스/지질의 물농도 비가 3과 6일 때 상대적으로 가장 높은 안정성을 보였다. Liposome powders were prepared by a freeze-drying method for the application to the field of drug carrier. The effect of maltose as a liposome stabilizer was studied on the stability and the drug-loading efficiency of the freeze-dried liposome powders. The particle size of liposomes before and after freeze-drying was determined to evaluate the liposome stability. The drug-loading efficiency was measured by Fluorescence spectrophotometer using calcein as a model drug. When maltose was added after the preparation of the liposomes, the liposomes was stable, compared to the case of maltose addition at the hydration procedure. By the addition of maltose, the liposome was stable for 30 days at $4{\sim}37^{\circ}C$, while the particle size of the liposome without maltose increased with time. The liposome showed relatively high stability when the maltose/lipids molar ratio was 3 and 6.

In recent years, there has been an increase in consumer demand for bottled waters. There is a perception that consumption of natural mineral water represents a healthy life style and that these products are relatively safe. In this study, the microbiological quality of 39 samples of bottled water, purchased from retail store in Korea, was investigated during the 2005. Applying pour plate method, the 1 mL of water samples were analyzed for the presence and enumeration of total general bacteria and Pseudomonas spp.. Nineteen samples representing 9 brands of bottled water contained general bacteria ($1.54{\times}10^2$ CFU/mL). In addition four samples contained Pseudomonas spp. and Camamonas acidovorans. The susceptibility of the strains tested against 25 antimicrobial agents, Pseudomonas fluorescens were resistant to Lincomycin, Amoxacilin/Clavulanic acid and Cefazolin (> $100{\mu}g/mL$). Also Comamonas acidovorans were intermediate to Cephalothin and resistant to Cefoperazone.

Background : Previous reports have mentioned the increased mortality of percutaneous coronary intervention (PCI) in elderly female patients compared with elderly male. The purpose of this study was to evaluate the clinical characteristics, coronary lesion, characteristics and differences of success rate of PCI between male and female elderly patients. Methods : Three hundred sixty six elderly patients (454 lesions), including 210 male (255 cases, 73.4±2.45 year-old) and 156 female (199 cases, 73.5±2.55 year-old) who underwent PCI at Chonnam National University Hospital between Jan '96 and Dec '98 (out of 3,030 patients during same period). We compared clinical characteristic, coronary artery lesion morphology, success and complication rates of PCI in elderly male and female patients. Result : Clinical diagnosis and risk factors for atherosclerosis were not different between two groups. Right coronary lesions were more common in female and left circumflex artery lesion less common in female patients. The success rate of balloon angioplasty was 93.2% (110/118) in male and 93.3% in (98/105) in female patients, and the success rates of stenting were 99.2% (136/137) in male and 100% (94/94) in female. Success rates of PCI were not different between two groups. Procedure-related mortality was one cardiac death (1/255, 0.39%) in male group only. Complications of elderly male were two occlusive dissection (OD: 2/255, 0.8%), three thrombotic occlusion (TO: 3/255, 1.2%) and two ventricular arrhythmia (VA) with shock (2/255, 0.8%). In 199 female patients, three OD (3/199, 1.5%), three TO (3/199, 1.5%) and two VA (2/199, 1.0%) developed. The complications rates were not different two groups. Conclusion : PCI in female patients older than 70 years can be performed with comparable success and complication rates to those of elderly male patients.(Korean J Med 60:456-462, 2001)

김윤아(Kim Yun Ah),유제일(Ryou Jay Il),신재홍(Shin Jae hong) 학습자중심교과교육학회 2015 학습자중심교과교육연구 Vol.15 No.10

The purpose of this paper is to report a development process and its result for an educational application(APP) to support students’ function learning through graphing activities in SMART education environments. Based on the review of literature related to students’ learning function, ‘car racing’ situations are selected as main backdrops for students’ graphing activities in the APP. Concrete contents such as shapes of racing tracks, configurations of screen at each step, and algorithms for a flow chart are also designed in consideration of psychological analysis in function learning and graph-drawing. Although how to integrate the APP into a classroom depends on the purpose and object of teaching in the moment, we expect that it could be a very useful tool for mathematics teachers to provide their students function instructions closely connected to real-life situations. 본 논문의 목적은 스마트 교육환경에서 그래프를 통해 함수개념 학습을 보조하는 어플리케이션을 개발하는 과정 및 결과를 제시하고 나아가 스마트 교육환경에서 수 학교육용 소프트웨어의 개발 연구에 대한 시사점을 얻고자 함이다. 어플리케이션을 개발하기에 앞서 그래프를 통한 함수 학습에 관한 선행연구들을 분석하고 이를 바탕 으로 자동차경주라는 어플리케이션 소재를 선정하였다. 함수⋅그래프 학습의 심리학 적 분석을 바탕으로 자동차경주 트랙의 모양, 화면의 구성, 필요한 알고리즘 등의 구 체적인 콘텐츠가 설계되었고, 스마트폰 교육용 소프트웨어 설계 전략과 수학학습용 도구로서의 충실도를 고려하여 수정, 보완을 거쳐 교사와 학생을 대상으로 ??-테스트 를 실시하였다. 교수의 목적과 대상에 따라 활용 방식은 다양하겠지만 개발된 어플리 케이션은 스마트 교육환경에서 함수교육 연구의 기초자료로서 학생에게 실생활과 연 계된 함수교육을 제공하는데 유용한 도구역할을 할 수 있을 것이라 기대한다.

본 연구는 북한이탈주민의 외상 후 성장을 조사하여, 심리적 특성에 따른 외상 후 성장에 영향을 미치는 요인을 파악함으로써 향후 북한이탈주민의 정신건강사업에 필요한 기초자료를 제공하고자 한다. 연구대상은 B시와 G시에 거주하는 북한이탈주민 145명으로 2016년 2월 1일~3월 10일까지 외상 후 성장, 사건 충격척도, 외상적 반추, 자아존중감, 적응유연성 을 설문조사하였다. 수집된 자료는 빈도와 백분율, 평균과 표준편차, t-test, one-way ANOVA, Pearson's correlation coefficient, hierarchial multiple regression으로 분석하였다. 연구결과 북한이탈주민의 외상 후 성장은 평균 29.64점이고, 여성인 경우, 종 교가 있는 경우, 외상적 반추 및 적응유연성의 점수가 높을수록 외상 후 성장의 점수가 높았으며, 이 차이는 통계적으로 유의 하였다. 북한이탈주민의 외상 후 성장에 영향을 미치는 예측요인은 적응유연성, 긍정적 자존감, 의도적 반추로 설명력은 총 54.2%(F=29.36, p<.001)로 나타났다. 따라서 북한이탈주민의 외상 후 성장과 적응유연성 및 긍정적 자존감을 촉진하고, 외상 적 반추를 활성화하는 중재가 체계적으로 제공되어야 함을 시사한다. This study examined the posttraumatic growth of North Korean defectors, the relation between their characteristics and posttraumatic growth and the factors influencing their posttraumatic growth, and explored methods of improving their mental health status. 145 North Korean defectors, who were trained in B city and G city, participated in the survey from February 1 to March 10, 2016. The posttraumatic growth, resilience, self-esteem, deliberate rumination, and impact of the (traumatic) event were measured using the PTGI (Posttraumatic Growth Inventory), RS (Rumination Scale, Resilience Scale), SES (Self-esteem Scale) and ISR (Impact of Event). The data were analyzed using the t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression. The mean scores were 29.64 for posttraumatic growth. There were significant positive correlations between posttraumatic growth and resilience and between posttraumatic growth and rumination. The influence of the independent variables on the total posttraumatic growth was examined using regression analysis. Models including the variables (resilience, positive self-esteem, and rumination) explained 54.2% of the variance for the posttraumatic growth. These findings demonstrate that it is essential for nurses to continuously intervene and help North Korean defectors so as to promote their posttraumatic growth and resilience. Furthermore, it is also necessary for nurses to find ways to develop ideal interventions in order to activate deliberate rumination.
