부분과 전체 - 근대 지역지리 방법론의 고찰

권정화(Jung Hwa Kwon) 한국지역지리학회 2001 한국지역지리학회지 Vol.7 No.4

근대 지리학 방법론 논쟁에서 가장 주요한 쟁점은 지역 지리학의 학문적 성격에 대한 논란이었다. 그러나 대부분의 논의는 지역 연구의 절차를 제시하기보다는 지역 지리학을 형이상학적으로 정당화하는 데 머물렀다. 본 연구에서는 이러한 견해를 비판적으로 검토하기 위하여 지역 지리학 방법론에 내재하는 전제들 가운데에서도 부분과 전체의 관계에 대한 존재론적 가정을 가장 중요한 준거로서 설정하였다. 대부분의 논의는 유기체론에 근거하여 지역을 복합적 존재로서 인식하고, 생명체와의 비유를 통해 지역의 속성을 파악해야 한다고 주장하였다. 그러나, 단위 지역이라는 전제의 한계와 더불어 단순히 요소들을 열거하는 데에 머물렀으며, 지역의 복합성을 포착하지 못하였다. 이러한 한계는 생활양식이라는 전제 위에서 출발한 데에서 오는 당연한 귀결이었다. Main debates in the modern geographical thoughts had been developed around the regional geography. Because regional geography had been regarded as a raison d`etre of geography, it remains solid status in geography curriculum. But unscientific nature of regional geography was the main problem of modern geography. modern geography has developed the logical legitimation of regional geography, instead of research procedures. We examine the logic of modern geographical thoughts from 3 worldview. Here we represented the part - the whole relationship as the primary category, and classify these into three type according to the implicit proposition about the relationship. One is the organic view, which assume that the whole is greater than the sum of the parts, this view was the primary proposition held by the modern geographers. This view regarded the region as organic complex, and presume the unit region which is irreducible to the elements. The other is mechanic view, which presuppose that the whole is the sum of the parts. This view comprehend region by means of spatial order, in order to simplify the complex reality. Then we compare real condition with assumption. These two view held static assumption. Now, the third view regarded the part- the whole relationship as being dynamic. Most geographers held the organic view, although someone suggest the idea of harmony, the others suggests the idea of complex. But these view presumes the pre-industrial society in which the genre de vie was main principle of social order. Therefore It could not comprehend the regional concept in the context of the urbanization and industrialization.

정상인과 알코올중독자의 음주허용기준과 인식에 관한 비교

권정화(Jungwha Kwon),전영민(Young Min Chun) 한국중독정신의학회 1997 중독정신의학 Vol.1 No.1

This study compared the age/gender norms and perceptions of drinking between alcoholics and nonalcoholics via interview and questionnaire. Age norms included acceptable drinking levels for the following age groups:16, 21, 40, and 60, both male and female. The results of this study were as follows: 1) Alcoholics were less tolerant in drinking in all categories(especially young males and females) than nonalcoholics. 2) The rank of order of acceptance of drinking by age/ ender of alcoholics was highest for a 40-year-old male, followed by a 60-year-old male, a 40-year-old female, and a 21-yearold male. However of nonalcoholics it was highest for a 40-year-old male, followed by a 40-year-old female, a 21-yearold male, and a 60-year-old male. The lowest acceptance of drinking was for adolescents, especially females in both groups. 3) Both groups showed a greater tolerance level for males than for females drinking. 4) Alcohlics showed a greater displeasure for facial flushing than nonalcoholics.

영어 읽기 시험의 문항 유형별 읽기 시험 수행 전략 사용 연구

권정화 ( Jeong Hwa Kwon ),이정원 ( Jeong Won Lee ) 충남대학교 인문과학연구소 2015 인문학연구 Vol.54 No.4

본 연구의 목적은 수능 시험의 문항 유형별로 학생들이 어떤 읽기 시험수행 전략을 활용하는 지에 대해 조사하고, 또한 이러한 전략 사용이 학습자들의 영어 읽기 수준에 따라 어떻게 달라지는 지에 대해서도 살펴보는 것이다. 이를 위해 105명의 고등학교 3학년생(남자 51명과 여자 54명)을 대상으로 수능 모의고사에서 15문항을 발췌하여 영어 읽기 시험을 실시하였고, 이와 함께 시험 수행 전략을 알아보기 위해 점검표를 함께 제시하여 각 문항을 푼 후 사용한 전략을 표시하도록 하였다. 그 결과 1)전반적으로 학습자들은 핵심 단어 찾기, 연역적 추론, 오답 제거하기 전략을 많이 사용한 반면, 지문 내용과 관계성이 적은 전략은 거의 사용하지 않았다. 2) 문항 유형별로 학습자들이 사용한 전략에는 차이가 있었는데, 이는 문항이 요구하는 측정 능력이 달라짐에 따라 그에 대응하기 위한 적절한 전략을 사용했기 때문으로 보인다. 3) 학습자들의 전략 사용을 영어 읽기 수준별로 살펴본 결과, 모든 수준에서 비슷하게 사용한 전략이 있었던 반면, 수준에 따라 다르게 사용된 전략이 있었는데, 특히상위 수준일수록 인지적 처리 과정으로 요구하는 연역적 추론 전략을 적극적으로 사용한 것으로 나타났다. 이를 통해 학습자들의 읽기 능력을 향상시키기 위해서는 문항 유형별·학습자의 영어 읽기 능력 수준별 시험수행 전략에 대한 명시적인 훈련이 필요함을 추론해볼 수 있다. The purpose of this study is to examine English reading test-taking strategies EFL learners use depending upon the item types of the test and their reading proficiency levels. For this study, 105 high school students (51 male and 54 female) were asked to take a mock CSAT and tick the strategies on the checklist they used when solving the test items. The outcomes can be summarized as follows: First, in English reading test the students tended to use the key word searching strategy and the deductive reasoning strategy. Also, they were not quite sure about the answers they chose, so they ticked the uncertainty strategy so often. Some strategies which do not have much to do with the text were rarely chosen for the facilitating strategies. Second, by and large, the students used different strategies when coping with different item types of the test. So when teaching for them to use English reading test-taking strategies explicitly, item types of the test need to be taken into account for their better achievement in the test. Finally, the strategy used frequently in all three levels(high, middle, and low) was the elimination strategy. The test situation where the students were expected to solve many question within limited time seemed to urge them to eliminate wrong answers in order to reduce cognitive burden to choose the right answer.

권정화 ( Jung Hwa Kwon ),이보영 ( Bo Young Lee ),배성호 ( Sheong Ho Bae ) 경북대학교 중등교육연구소 2004 중등교육연구 Vol.52 No.2

The purpose of this research is to fulfill learners` various learning needs and to find the ways to improve the effect of teaching-learning in geography through lessons planning to apply to contemporary educational situations. The main results of this research are as follows. 1) This research showes that the natural scientific principle learning is not effective in the cooperative learning of geography class. 2) In the group that the difference of students` level is various, STAD model could be more useful than Jigsaw I model. 3) STAD model is useful as the standard of classes and could confirm the necessity of getting a concept about terms used in classes. 4) Problem-solving ability and reciprocal cooperation were built and the communication skills was also improved while students went through and solved the individual and group tasks. 5) The cooperative learning of heterogeneous groups had little effect in high and low ability groups. The high ability groups think that they learn little from the low ability groups in the group discussion learning. The low ability groups have a difficulty in learning contents of discussion activities. As a result, this research argues that the cooperative learning in geography class with another effective class styles can improve class and raise its quality. In addition, this study suggests that by investigating a topic, problem and concept closely, the opportunities to broaden the experiences are needed to be offered. And in the heterogeneous group, the model must be developed to perform proficiency level class at the same time.(Kyungpook National Univ./Hyoryung High School)

치매노인 주 돌봄제공자의 자기돌봄이 소진에 미치는 영향

권정화 (Kwon, Jeong Hwa),홍(손)귀령(Hong, Gwi-Ryung Son) 한국간호과학회 2021 Journal of Korean Academy of Nursing Vol.51 No.2

Purpose: The purpose of this study was to identify the influence of self-care on burnout experienced by primary family caregivers of persons with dementia. Methods: The subjects of the study were 156 primary family caregivers of persons with dementia at home in Korea. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficient, and hierarchical multiple regression using IBM SPSS Statistics ver. 24.0 for Windows. Results: The mean scores for self-care and burnout were 42.35 and 61.60, respectively. Self-care, subjective health status, living with a person with dementia, and behavioral and psychological symptoms of dementia were significant factors affecting burnout in family caregivers. Self-care was identified as the strongest factor affecting burnout, explaining 13.9% of burnout with controlling factors in caregivers and care receivers. Conclusion: To prevent burnout in primary family caregivers of persons with dementia, self-care of family caregivers should be emphasized. In nursing education, family caregivers should be recognized and approached as nursing clients who are responsible for taking care of their health. In nursing practice and research, digital self-care or self-care improvement intervention programs should be designed to help family caregivers, and further studies on self-care centered on health of family caregivers should be conducted.

Pueraria mirifica 뿌리를 실온에서 70% EtOH 수용액으로 추출하고 이 추출물을 EtOAc 분획, n-BuOH 분획, H2O 분획으로 나누었다. EtOAc 분획에 대하여 silica gel, octadecyl silica, 및 Sephadex LH-20 c.c.를 반복 실시하여 4종의 화합물을 분리, 정제하였다. Nuclear magnetic resonance, infrare, 및 mass spectrometry의 spectroscopic data를 해석하여, 화합물 1-4를 각각 megastigm-5-en-3,9-diol, linarionoside B, 3,5,6,9-tetrahydroxymegastigm-7-ene 및 3,4,9-trihydroxymegastigma-5,7-diene으로 구조를 결정하였다. 화합물 1-4 모두 P. mirifica에서는 이번에 처음으로 분리된 화합물이다. The roots of Pueraria mirifica were extracted with 70% aqueous ethyl alcohol and partitioned into ethyl acetate (EtOAc), n-butyl alcohol (BuOH), and H2O fractions, successively. From the EtOAc fraction, four norsesquiterpenes were isolated through the repeated silica gel, octadecyl silica gel and Sephadex LH-20 column chromatographies. On the basis of physicochemical and spectroscopic data including nuclear magnetic resonance (NMR), mass spectrometry, and infrared spectroscopy, the chemical structures were identified as megastigm-5-en-3,9-diol (1), linarionoside B (2), 3,5,6,9-tetrahydroxymegastigm-7-ene (3) and 3,4,9-trihydroxymegastigma-5,7-diene (4). Especially, the configuration of the anomer hydroxyl group was determined as a from the coupling constants of the anomer proton (J =8.0 Hz) in the 1H-NMR spectrum. These compounds were isolated for the first time from the roots of P. mirifica in this study.

지리 교육의 미래를 위한 구도 설정

권정화(Jung-Hwa Kwon) 대한지리학회 2010 대한지리학회지 Vol.45 No.6

지리교육은 지난 한 세기 동안 한국 사회의 근대 국민 교육에 지대한 기여를 하였으나 최근 위기에 직면해 있다. 본고에서는 당면한 지리교육의 위기에 대처하기 위하여 정보 양식이라는 측면에서 사회 변화의 교육적 함의를 고찰하였다. 최근 논의되는 지식의 성격 변화에 부응하여 청소년 문화를 배려한 정서 중심의 지리교육이라는 방향을 제시하였다. 그러나 현실적으로는 국민정서의 측면을 무시할 수 없기 때문에 국토학, 주택정의론, 지역학 등의 과목 주제를 중심으로 내용을 구성하면서 정체성 형성에 기여하기 위한 교육적 차원을 강화하는 방향을 제안하였다. The geography education in korea has contributed to citizenship education since the late 19th century. But today geography has seen crisis in the school curriculum. In order to overcome this crisis we investigate educational implication of social change. Based on M. Poster’s theory of mode of information, we examine changing nature of knowledge and its implication on school. These aspects reflect teenager culture and emotional aspect of geography education. However we needs support from the national ethos. We suggest a few directions of geography education, contribution of cultural landscape to korean identity, housing and land justice, future cities, geopolitics and culture area.

영국의 2014 개정 지리교육과정의 특징과 그 시사점

심승희 ( Seung Hee Shim ),권정화 ( Jung Wha Kwon ) 한국지리환경교육학회 2013 한국지리환경교육학회지 Vol.21 No.3

본 연구는 영국의 2014년 개정 지리교육과정의 주요 특징과 그 과정에서 도출된 주요 논쟁들을 살펴보고 우리나라 교육과정에 주는 시사점을 도출하고자 하였다. 이번 영국의 교육과정 개정은 지난 13년동안 노동당 정부 하에서 진행되어 온 학습자 중심의 교육과정, 교과통합적이고 기능중심적인 교육과정이 ‘무엇을 배울 것인가’의 문제를 간과했다는 비판에서 출현했다. 그에 따라 이번 교육과정은 교과기반, 지식기반 교육과정을 추구하는데, 국가교육과정은 각 교과별로 ‘핵심 지식’을 제시하고 각 학교와 교사는 이 핵심 지식을 중심으로 자율적으로 가르칠 것을 표방한다. 지리교과가 선정한 핵심적 지식과 기능은 ‘위치 지식,’ ‘장소 지식’, ‘자연 및 인문지리’, ‘지리적 기능과 현장답사’로서, 이는 위치 및 지역지리 지식의 강조라는 전통적 지리교육의 강화, 그리고 지리 지식의 명료화, 권위화, 고정화라는 지향성을 뚜렷이 보여주고 있다. In this study I researched the characteristics of 2014 Revision of Geography National Curriculum in UK and its implication. A 2014 Revision of National Curriculum derived from the Conservative Government`s criticism that the curriculum of UK during the past 13 years under the Labour government had pursued learner-centered, integrated subjects-centered, skill-centered national curriculum, therefore had ignored ‘what should the pupils learn?’. This Revision of National Curriculum pursues the subjectbased, knowledge-based national curriculum. Thus each subject curriculum had to select ‘essential, core knowledge’ of the subject. Geography national curriculum selected 4 core knowledge; locational knowledge, place knowledge, physical and human geography, geographical skills and fieldwork. In consequence, this geography national curriculum is oriented at the emphasis of traditional geography education and the clarification and authorization and fixation of geographical knowledges.
