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.

N/A 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)

Conclusion: The results indicate that aroma hand massage and hand massage are effective in reducing anxiety and can be complementary alternative interventions for women having gynecology surgery under local anesthesia.

초현실주의 표현기법과 오브제의 표현 특성을 통한 마르텐 바스의 아트퍼니처 분석

김윤아 ( Kim¸ Yun Ah ),김남효 ( Kim¸ Nam Hyo ) 한국기초조형학회 2021 기초조형학연구 Vol.22 No.4

본 연구의 목적은 초현실주의의 표현 방식과 오브제의 프로세스를 통하여 현대 아트퍼니처의 특성을 분석하고 창의적인 디자인 방법론을 마련하는 것이다. 연구 범위는 초현실주의 시대와 마르텐바스(Maarten Baas, 1978~)의 대표적인 Smoke, Clay, Real time 각각의 시리즈 작품으로 한정하였다. 본 연구의 방법은 다음과 같다. 2장에서 초현실주의의 이론적 고찰을 진행한 뒤, 나타난 특징을 중심으로 4가지 키워드(결합성, 우연성, 환상성, 모호성)로 분류한다. 이후 초현실주의 오브제의 특성을 표면적, 내면적으로 나누고, 표면적 특성을 바탕으로 4가지(단일-결합 오브제, 정적-동적 오브제), 내면적 특성을 바탕으로 3가지(의식적, 전의식적, 무의식적 오브제)로 재구성하였다. 3장에서는 아트퍼니처의 개념을 살펴본 뒤, 도출된 기법과 오브제 표현특성을 중심으로 마르텐바스의 작품을 분석하였다. 분석 결과를 정리하면 다음과 같다. 첫째, 초현실주의의 표현기법과 오브제의 표현특성은 현재에도 여전히 사용되고 있어 초현실주의의 방법론을 연구하고 적용하는 것이 중요함을 알 수 있었다. 둘째, 초현실주의 작가들은 미술창작과정에서 오직 손재주와 신체 활동에만 집중하던 그들의 관심을 지적인 기반으로 전환함으로써 인간의 내면에서 오는 자유로운 표현을 중시하고자 오브제를 제작하였지만, 개념의 비중이 커진 현대에는 손으로 제작하는 아트퍼니처도 각광받고 있었다. 셋째, 초현실주의의 오브제 표현 특성 중 동적인 오브제는 현대에 들어서면서 미디어 아트까지 하나의 오브제로 확대 된 것으로 보였다. 결론적으로, 가구의 예술적인 표현과 아트퍼니처의 필요성을 충분히 야기하는 시대로 변화하는 시점에서, 제공된 구체적인 표현특성을 통하여 아트퍼니처를 바라보고 새로운 공간과 조형에 적용하는 것은 현대의 디자이너들에게 더 깊이 있는 방법론을 찾을 수 있도록 기여 할 것이다. The purpose of this study is to analyze the characteristics of modern art furniture through the expression method of surrealism and the process of objects and to prepare a creative design methodology. The scope of research was limited to Surrealism and Maarten Baas(1978~) representative Smoke, Clay, and Real Time series works. The method of this study is as follows. After a theoretical study of surrealism in Chapter 2, it is classified into four(combinability, contingency, fantasy, and ambiguity) focusing on the characteristics that have appeared. Subsequently, The Characteristics of Surrealist Objects were divided into surface and inner, and reconstructed into four(single-combination object, static-dynamic object) based on surface characteristics and three(conscious, preconscious, and unconscious object)based on inner characteristics. In Chapter 3, the concept of art furniture is summarized, and Bass's works are analyzed focusing on the expression technique and the expression characteristics of objects. The analysis results are summarized as follows. First, the expression techniques of Surrealism and the expressive characteristics of objects are still used today, so it is important to study and apply the Surrealism methodology. Second, surrealist artists produced objects to emphasize the free expression that comes from the inner world of man by turning their attention focused only on dexterity and physical activity to an intellectual basis in the art creation process. Conversely, nowadays, where the importance of concepts has increased, art furniture made by hand has also been in the spotlight. Third, among the object expression characteristics of surrealism, dynamic objects seemed to have been expanded to media art as a single object as it entered the modern era. In conclusion, the modern society is at a time when the artistic expression of furniture and the necessity of art furniture are sufficiently desired. Studying art furniture through the specific expressive characteristics of surrealism and applying it to new sculptures will contribute to finding newer and more valuable methodologies for modern designers.

Sjogren`s syndrome (SS) is a chronic, slowly progressive autoimmune disease characterized by lymphocytic infiltration of the exocrine glands leading to dry mouth and dry eyes accompanied by a variety of autoimmune phenomena. Despite the obvious difference in the affected organ, patients with SS and those with Hashimoto`s thyroiditis share several histologic and genetic features. The immunopathologic findings of Hashimoto`s thyroiditis and Sjogren`s sialadenitis show similarities such as infiltration by activated T lymphocytes and inappropriate expression of HLA class II molecules by the epithelial cells. It has been reported that up to 50% of patients with SS develop autoimmune thyroid disease in the clinical course, and patients with Hashimoto`s thyroiditis have symptoms related to SS frequently. In Korea, the ocurrence of SS in association with Hashimoto`s thyroiditis has not been reported so far, although it is considered to coexist occasionally. We report a case of primary SS in a patient with Hashimoto`s thyroiditis who had been treated with levothyroxine.

Purpose: The purpose of this study was to examine the effects of light therapy on sleep disturbance and depression in climacteric women with menopausal symptoms. Methods: The research design was a nonequivalent control group pre test-post test design. Data were collected from September 29, 2013 to November 11, 2013. Participants included 17 climacteric women in an artificial light therapy group, 17 climacteric women in a sun light therapy group and 16 climacteric women in a control group. Measures consisted of the sleep disturbance, depression, melatonin, and serotonin. Results: There was a statistically significant difference of Korean Sleep Scale A (F=53.87, p<.001), and melatonin (F=31.19, p<.001) among three groups. There was a statistically significant difference of Self-Rating Depression Scale (F=121.86, p<.001), and serotonin (F=102.37, p<.001) among three groups. Conclusion: Artificial and sun light therapy can be applied as a supportive nursing intervention to subjects with sleep disturbance and depression in climacteric women with menopausal symptoms. Artificial and sun light therapy is expected to be a complementary alternative intervention for health management of the subjects with sleep disturbance and depression in climacteric women with menopausal symptoms.
