Fractal geometry has become one of prospective research approaches as the complex structure of natural entities is not easily characterized by traditional Euclidean geometry. With the fractal geometry, we can better decipher the complex structure and identify natural and anthropogenic agents of landscape patterns occurring at different spatial scales. The usefulness of fractal, however, has not been fully appreciated among Korean academic societies, especially in ecological and limnological fields. We attempt to address three points in this study. First, we introduce the concept and dimension of fractal and review relevant research approaches, especially with respect to ecological and limnological phenomena. Second, we explore possible applications of fractal to some aspects of geography and land use characteristics in South Korea. For the analyses of fractal dimensions, we used data published in other studies previously and collected for this study. Data were analyzed by a perimeter/area method of fractal dimension for the spatial distribution of global solar radiation and leaf area index, and the movement of wild boars in forested landscapes of mid-eastern Korea. The same approach was also applied to the water channel of a hypothetical river and the shape of reservoirs in Yongin, Kyunggi Province. Finally, we discuss the results and key issues to consider when a fractal approach is employed in ecology and limnology.

Purpose: Flexed posture commonly increases with age in older women and is characterized by an excessive curvature in the thoracic spine (kyphosis), forward head posture, and decline in height. This study was conducted in order to determine the relationship between flexed posture, physical performance, and psychosocial factors in community dwelling elderly women in Korea. Methods: Fifty-two subjects with thoracic kyphosis of $40^{\circ}C$ or greater participated in this study. Flexed posture was measured using kyphosis angle (KA), forward head posture (FHP), and round shoulder (RS), and physical performance was evaluated using the short physical performance battery (SPPB), grip strength, and static and dynamic balance. Psychosocial factors were measured using depression and the quality of life (QOL). All data were analyzed using SPSS 18.0 software for windows. Results: KA showed significant correlation with SPPB score (r=-0.447) and dynamic balance (r=0.426) (p<0.05) depression (r=0.405) and QOL (r=-0.464) but not with grip strength and static balance in elderly individuals. FHP and RS showed significant correlation with SPPB score (r=0.002, r=-0341) and dynamic balance (r=-0.278, r=0.346) (p<0.05) but not with psychosocial factors. Conclusion: These findings suggest that flexed posture provides meaningful information about physical performance and psychosocial factors in elderly women. Our data suggest that the flexed posture may need to be addressed as part of the health management process for elderly women.

Objectives : The purpose of this study is to investigate the relationship between the triallelic serotonin transporter gene and stressful life events to determine their effect on depression with alcohol dependence. Methods : Ninety-five hospitalized patients with alcohol dependence (73 male, 22 female) were enrolled in this study. Thirty-two (33.7%) of the total patients were diagnosed with major depressive disorder and dysthymic disorder by Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-IV. The characteristics of stress were evaluated using the stressful life events scale, and depressive symptoms were assessed using the depression scale (Beck Depression Inventory, BDI). Alcoholism with depression (n = 32) and alcoholism without depression (n = 63) were genotyped for the triallelic serotonin transporter gene ($L_A$ : higher expressing allele, $L_G$/S : lower expressing allele). Results : There was no significant difference in the allele frequency between the depression group and the non-depression group (${\chi}^2$ = 0.345, p = 0.619). $L_G$/S alleles had more comorbid depression in the higher score of stressful life events scale [Mental-Haenszel (MH)-${\chi}^2$ = 4.477, p = 0.034]. But there was no significant difference in the comorbidity according to the scores from the stressful life event scale in the $L_A$ alleles (MH-${\chi}^2$ = 0.741, p = 0.399). In the results, alcohol-dependent individuals with $L_G$/S alleles had more comorbid depression than those with $L_A$ alleles when they had experienced severe stressful life events (MH-odds ratio = 2.699, p = 0.028). Conclusions : These results suggest that there is no direct relationship between triallelic serotonin transporter gene and depression in the alcohol dependent patients. But alcohol dependent individuals with the lower expressing alleles of the serotonin transporter gene were more susceptible to depression than those with the higher expressing alleles in response to stressful life events.

1993년 10월에서 1994년 9월의 기간동안 인제대학교 부산 백 병원에서 비Q파 심근경색으로 진단 받은 23명의 환자를 대상으로 그 임상적 특징 및 관상동맥조영술을 분석하여 Q파 심근경색에 비해 측부순환의 형성 빈도는 높으나 좌심실조영술상 비정상적인 심실 운동의 출현 빈도는 낮음을 관찰하였기에 문헌 고찰과 함께 보고하고자 한다. Despite of haying smaller infarct size and better left ventricular function, patients with non Q wave myocardial infartion(MI) have been reported high rate of late mortality due to recurrent MI, precipetated by more residual viable tissues in the perfusion zone of infarct-related arteries. To evaluate the clinical characteristics and coronary angiographic findings of non Q wave myocardial infarction, 23 patients with non-Q wave myocardial infarction who were admitted between Oct.1993 and Sep. 1994 were reviewed and analyzed retrospectively. The results were as follows : 1) The mean age was 40-50 Years. Male to female ratio was 6:1. Most common risk factor was smoking 2) Most common electrocardiographic finding was anterior or lateral wall infarction. Five patients(21.7%) among total twenty three patients had normal electrocardiographic finding 3) Selective coronary angiographic was performed in nineteen patient. Each patient was classified as haying one-,two-,three vessel coronary artery disease. In one case(5.3%), angiographic finding was normal. Seven cases(36.8%) were one vessel disease. And four cases were three vessel disease Coronary artery with complete stenosis(100%) was present in five patients and low grade obstruction (<50%) was present in three patients. 4) Formation of collateral circulations was observed in 73.7% and incidence of abnormal left ventricular wall motion was less frequent.

사회정의 관점의 다문화 교육을 위한 제재 타당성 검토 - 고등학교 문학 교과서 수록 소설 작품을 중심으로

장현정,장성민 한국 리터러시 학회 2021 리터러시 연구 Vol.12 No.4

This study reviews the validity of multicultural reading materials contained in high school literature textbooks from the perspective of social justice education. As an analysis of five novels using Picower’s (2012) six elements of multicultural social justice curriculum design as key categories, current reading materials mainly focused on 1-3 levels (i.e., self-love and knowledge, respect for others, and issues of social injustice). They do not properly show the value of cultural difference by approaching the practical matters of multicultural social justice from a personal dimension or by assuming them as common humanity issues such as interpersonal romantic relationships. Although the limitations of reading materials are partially compensated for through instructions or learning activities in textbooks, their effects may differ depending on instructors or contexts, which are points of concern. This study is meaningful in that it extended the focus of previous multicultural education, which was mainly focused on the personal dimension, to the social dimension. 이 연구는 사회정의 교육의 관점에서 고등학교 문학 교과서에 수록된 다문화 소설제재의 타당성을 검토하려는 목적으로 수행되었다. Picower (2012)가 제안한 다문화 사회정의 교육의 여섯 단계를 핵심범주로 삼아 교과서에 수록된 소설 5편의 타당성을 분석한 결과, 현재의 제재들은 주로 1~3단계에 집중되어 있음을 확인할 수 있었다. 자아(정체성), 배려, 존중 등의 개인적 차원에 치우침으로써 다문화 사회의 실제적 문제를 소략하게 다루거나, 다문화 사회정의의 문제를 ‘사랑’과 같은 보편적 문제로 접근함으로써 문화적 차이로부터 기인하는 사회적 문제의 특수성을 제대로 다루지 못하는 것이다. 교과서에서 안내문이나 학습 활동을 통해 제재의 한계를 부분적으로 보완하기도 하나, 이러한 항목들이 지닌 효과가 교사나 교수·학습 맥락에 따라 상이할 수 있다는 점에서 앞으로 더 고민할 지점이 있다. 이 연구는 개인적 차원에 주로 맞추어지던 기존 다문화 교육의 초점을 사회적으로확장하였다는 점에서 의의를 찾을 수 있다.

소통 중심의 다문화 교수·학습 설계가 상호문화적 감수성 향상에 미치는 영향 - Banks의 이론적 모형의 구현

The study aims to analyze the impact of communication-centered multicultural teaching and learning on the improvement of intercultural sensitivity. For the purpose of the study, communication-centered multicultural teaching and learning based on Banks' theoretical model was designed. The analysis was conducted by applying binary group pre- and post-implementation tests on elementary school students. In order to support multicultural learners to interact with audiences at different levels, the teaching and learning model has been designed, incorporating the five dimensions of “content integration, knowledge construction process, prejudice reduction, equity pedagogy, and an empowering school culture and social structure.” Changes were tracked by measuring “acceptance” and “adaptation” that correspond to cultural relativism within the developmental model of intercultural sensitivity. The analysis found that communication-centered multicultural teaching and learning had a significant effect on “adaptation” with an effect size of medium. On the other hand, it was confirmed that there was no significant effect on “acceptance,” which could be interpreted as a kind of ceiling effect for elementary school students. 이 연구는 Banks의 이론적 모형에 기반하여 소통 중심의 다문화 교수·학습을 설계하고, 초등학생 학습자를 대상으로 이원집단 사전-사후 검사를 적용하여 상호문화적감수성 향상에 미친 영향을 실증적으로 분석하였다. 이 연구는 다문화 학습자로 하여금 여러 층위의 독자와 상호작용하도록 지원하기 위해 ‘내용 통합, 지식 구성 과정, 편견 감소, 공평한 교수법, 학생의 역량을 강화하는 학교 문화와 조직’의 다섯 차원으로부터 5차시의 교수·학습을 설계하고, 상호문화적 감수성 발달 모형 가운데 문화상대주의에 해당하는 ‘수용’과 ‘적응’을 측정하여 그 변화를 추적하였다. 분석 결과 소통중심의 다문화 교수·학습은 ‘적응’에 중간 정도의 효과크기를 보이며 유의한 영향을미치는 것으로 나타났다. 반면 ‘수용’에는 유의한 영향을 미치지 못한 것으로 확인되었으며, 이는 초등학생 학습자에게 있어 일종의 천장 효과가 존재하는 것으로 해석될수 있었다.
