이보리,정혜영 이화여자대학교 교과교육연구소 2014 교과교육학연구 Vol.18 No.3

본 연구는 초등영어에서의 문자 해독 능력 및 읽기 유창성과 더불어 영어 흥미도가 독해력에 미치는 영향을 규명하고, 영어 흥미도가 문자 해독능력 및 읽기 유창성과 독해력 간의 관계를 매개하는지 밝히고자 A 사립초등학교 6학년 아동 총 95명을 대상으로 문자 해독 능력, 읽기유창성, 독해력 및 영어 흥미도 검사를 실시하였다. 문자 해독 능력과 읽기 유창성 측정을 위해 Good과 Kaminski(2011)에 의해 고안된 읽기 능력 측정 도구인 DIBELS(Dynamic Indicator of Basic Early Literacy Skills) Next Assessment를 사용하였다. 독해력 측정을 위해서는 한국형 렉사일 검사인 E-LQ 온라인 검사를 실시하였으며, 영어에 대한 흥미도를 파악하기 위하여 영어 학습 및 영어책에 대한흥미도 설문을 실시하였다. 수집된 자료는 한글 SPSS 18.0 프로그램을 사용하여 Pearson 적률상관계수를 산출하였고 표준다중 회귀분석과 3단계 매개 회귀분석 기법을 실행하였다. 본 연구결과, 문자 해독 능력과 읽기 유창성은 독해력과 유의미한 정적 상관을 보였다. 또한 문자 해독 능력의 하위 요소인 문자 인식, 음소 인식, 단어 인식과 독해력과의 관계에서는 문자 인식을 제외한 두 요인이 독해력과 유의한 상관을 보였으며, 세 요인 모두 독해력에 유의한 영향을 미쳤으며, 영어 흥미도는 독해력과 유의미한 정적 상관을 보였다. 본 연구를 통하여 초기 읽기 단계에서 습득되는 문자인식, 음운인식, 단어 인식 같은 문자 해독 능력은 독해력에 큰영향을 미치므로 훗날 능숙한 읽기 능력을 위해 습득 되어야할 매우 중요한 요소임을 제시하였다. This study examined the effects of the decoding skills, reading fluency, and interest in English on reading comprehension. In addition, the mediating role of interest in English was examined. The reading measures were administered individually to 95 sixth grade students in Seoul, Korea to assess and analyse the students' decoding skills (Letter Naming Fluency, Phonemic Awareness, and Word Fluency), reading fluency (Oral Reading Fluency), and reading comprehension skills (E-LQ online test). The findings can be summarized as follows. First, multiple regression analysis revealed that both decoding skills and reading fluency are highly correlated with reading comprehension skills. Among the subordinates of decoding skills Word Fluency showed the highest effect on reading comprehension skills. Secondly, simple regression showed that student interest in English does effect reading comprehension skills. Thirdly, the mediating role of an interest in English between the decoding skills and reading fluency respectively with reading comprehension was not statistically significant; however, interest in English showed a strong relationship with decoding skills, reading fluency, and reading comprehension skills. This can be explained by assuming that the correlation with decoding skills, reading fluency, and reading comprehension was so strong that the mediating effect of interest in English did not show statistically. There are limitations, therefore, in generalizing the effects as the results above indicate. The study was conducted with only 95 sixth grade students in one private elementary school; therefore, pedagogical and theoretical implications and recommendations for further research are presented.

This study examined consumers' perception on corporate social responsibility (CSR). As the market is becoming more competitive and consumers awareness of social problems is rising, voices demanding CSR get the attention of many companies. This study attempted to analyze how consumers perceive the concept and the range of CSR. Consumer demand for CSR activities and their response to companies' CSR activities were analyzed. CSR activities were classified into 4 dimensions: company's internal management, consumer-related, the government-related and society-related CSR activities. The major findings of this study are as follows. First, consumer-related activities were perceived as the most appropriate and needed CSR activities, while the perception of society-related activities was lowest. Second, respondents who have higher sense of responsibility as consumers have more positive attitude to CSR activities and have more intention to purchase a product/service that is related to the companies' CSR activities. Third, respondents' subjective norm toward CSR has an effect on the response to CSR activities.

Health belief is an important factor influencing performance of health behaviors. Young adulthood is critical period to establish health belief and behaviors for a healthy life. As health professionals, nurses can help young people establish more positive health belief and carry out health behaviors more effectively. Osteoporosis is a age-related metabolic disorder and currently there is no cure. But there are measures that can prevent or deter the development of osteoporosis. Osteoporotic prevent health promotion behavior may be more effective at early adult when make information of peak bone mass. But before attempting to help them it is necessary to identity their osteoporosis health beliefs and health promoting behaviors. The purpose of this study was to investigate the relationship between college women's osteoporosis health belief and health promoting behaviors. The subject were 296 women students from any universities in Seoul. The data were collected by a self-report questionnaire during the period from April to May. The instrument used for this study were made of General characteristics(18 items). Osteoporosis health belief developed by Kim, Horan & Gendler(1991) (42 items) and health promoting behaviors developed by Walker(30 items). The data were analyzed by SPSS PC + program using descriptive statistics, ANOVA, T-test and Pearson's Correlation Coefficient. The Result of this study were as follows. 1. The general characteristics The general characteristics of this study subjects showed that most students were 20 years in the nursing group and 21 years in the non-nursing group. The most house pattern was 'living with parents'(32.77%, 35.14%) in both nursing and non-nursing group. The most religion was 'Christian' (17.91%, 22.97%) in both nursing and non-nursing group. The most income range was 3,000-5,000 thousands in month (17.57%. 16.22%) in both groups. 2. The characteristics of students to Universities by department The students in the nursing group was 48.65% and non-nursing group was 51.35%. Most students were 2nd and 4th grade(each 13.18%) in nursing group and 4th grade(16.89%) in non-nursing group. The most students who were attended cultural subjects related health were 45.83% in nursing group and 43.42% in non-nursing group. The students who intend to attending were 63.19% in nursing group and 61.84% in non-nursing group. 3. The health history Most students don't have fracture-experienced mothers or grandmothers in nursing group and non-nursing group(76.39%, 80.16%). In addition, most students' mothers or grandmothers don't have kyphosis in nursing group and non-nursing group (93.06%, 91.41%) Most students don't experience fracture in both groups(88.89%, 83.91%) and most students don't smoke in both groups( 96.53%, 90.62%) The more students in nursing group don't exercise regularly (88.19%) than non-nursing group (76.41%). In addition, most students in both groups drink alcohols(70.14%, 66.25%) and coffee(79.17%, 80.16%) 4. The health belief and the health promoting behavior The mean score of the osteoporosis health belief was 117.63±13.06 and the mean score of health Promoting behaviors was 83.39±11.86. 5. The health belief according to general characteristics Statistically Significant difference was founded in the benefit of calcium intake according to ages (F=4.195, P=O.OO). 6. The health belief according to departments The barrier of calcium intake was higher in non-nursing group than nursing group(T=-2.64, P=O.OO9) and health motivation was higher in nursing group than non-nursing group(T=3.77 P=O.OOO). Health motivation according to . grade was the highest in 2nd grade(F=4.957 P=O.OO2). The benefit of exercise was higher in the group which have attended cultural subjects related health than don't have(T=2.067, P=O.04O). The health motivation was higher in the group which have attended cultural subjects related health than don't have(T=l.999, P=O.047). 7. Health promoting behavior according to general characteristics The self realization according to ages was high in 23 year-group(43.93±4.23). The calcium intake diet in boarding students was the highest(45.21±14.12), and Personal relationship was the highest in the same group(9.71±1.80). In addition, the group which have income 1,000-3,000 thousands monthly was the highest in stress control(9.47±1.52). 8. Health promoting behavior according to departments Health responsibility was the highest in 2nd grade(9.22±4.33) and in the group which have attended cultural subjects related health(8.83±3.24) In addition, the group which have attended cultural subjects related health(6.866±1.14) was higher in self realization and they also do bone-stimulated exercise more (9.04±6.99). Health responsibility was higher in the group which intend to attending cultural subjects related health(8.68±2.86) than the group which don't want. 9. The relationship in health belief and health promoting behavior of osteoporosis The benefit of exercise has positive correlation with health responsibility(r=.26), self realization (r=.21) and bone-stimulated exercise(r=.26). The benefit of calcium intake has positive correlation with health responsibility(r=.20). In addition, barrier of exercise has negative correlation with bone-stimulated exercise(r=.26) and health motivation has positive correlation with health responsibility, stress control and self realization. In conclusion, further extensive research might be needed about college women's osteoporosis prevention. Moreover, educational program about exercise and diet might be developed and implemented in hospitals and communities.

Objectives: Excessive melanin production leads to skin pigmentation, which causes various cosmetic and health problems. Citrus unshiu Markovich peel (CS) and Cimicifuga dahurica (CD) have long been widely used as a oriental medicinal plant because of their pharmacological properties including anti-ulcer, anti-oxidant, and anti-inflammatory properties. Methods: In this study, we investigated the inhibitory effects of CS, CD extracts or CS:CD=1:2 mixture on melanogenesis according to the various extraction methods. CS and CD extracted were prepared by ethanol extraction (EE), ultrasonification extraction (USE), Supercritical extraction (SCE), reflux extraction (RE), respectively. Results: DPPH radical scavenging and tyrosinase inhibitory activity of CD extracts or CS:CD=1:2 mixture were increased in dose-dependent manners. In addition, we evaluated the effect of CS, CD extracts or CS:CD=1:2 mixture on tyrosinase activity and melanogenesis in α-melanocyte stimulating hormone-induced B16-F10 melanoma cells. CS, CD extracts or CS:CD=1:2 mixture significantly inhibited tyrosinase activity and melanogenesis at 10-200 μg/mL. Conclusions: Therefore, our study suggests that CS and CD extracts have potential as a safe treatment for excessive pigmentation or as a natural ingredient in cosmetics.

As the COVID-19 pandemic continues to rage, developing distance education competence became indispensible for pre-service teachers in the school of education. An instructional model called ‘CONTACTED model’ was developed and investigated if this model can be applicable for online teaching practice for pre-service teachers and how effective it would be. Ten volunteer junior pre-service English teachers at a school of education participated in the online teaching practice for three months, teaching 63 students from 18 high schools in the area. While going through the four steps; ‘Class content selection and video material creation,’ ‘online class operation,’ ‘online mentoring,’ and ‘online golden bell contest’; the pre-service teachers successfully applied four elements of the CONTACTED model including ‘(Authentic) Task,’ ‘Content,’ ‘Technology,’ and ‘Community.’ Additionally, they were able to enhance basic knowledge, class implementation, and student guidance competence. Through a survey and interviews, the pre-service teachers reported that they could develop the abilities of how to apply theory into practice(‘Content’), how to improve technical skills to deal with online videos and tools(‘Technology’), and how to communicate well with students with the help of other pre-service teachers, the supervisor, and assistance teachers(‘Community’). It is concluded that the CONTACTED instructional model was suitable for online teaching practice and effective for enhancing distance education competence for the pre-service teachers. Limitations and implications are presented as well. 코로나 19의 장기화로 인해 원격수업은 이제 일반화되었고, 이러한 포스트코로나 시대를 살아가고 있는 사범대 예비교사들에게 원격교육 역량 강화는 필수가 되었다. 이를 위해 본 연구에서는 예비교사들을 위한 CONTACTED 수업모형을 개발하였고, 이 모형의 온라인 교육실습 적용 가능성과 효과성을 탐색하고자 하였다. 한 사범대 3학년에 재학 중인 10명의 예비 영어교사들은 3개월에 걸쳐 18개 고등학교에 재학 중인 총 63명의 학생들을 대상으로 온라인 교육실습을 진행했다. ‘수업내용 선정 및 동영상 자료 제작’, ‘온라인 수업운영’, ‘온라인 멘토링’, ‘온라인 골든벨 대회’와 같이 4가지 과정을 거치는 동안 예비교사들은 CONTACTED 모형의 4가지 요소인 ‘과제(Task)’, ‘내용(Content)’, ‘테크놀로지(Technology)’, ‘학습공동체(Community)’를 잘 적용해나갔으며, 원격교육에 대한 기본소양과 수업실행 및 학생지도 능력도 신장시켜나갔다. 설문 및 인터뷰 조사 결과, 온라인 수업과 관련한 ‘과제’를 수행하는 동안 이들은 본인이 가진 지식을 실제 수업에 적용하는 방법을 배우고(‘내용’), 동영상 제작 및 온라인 툴의 사용 기술을 익혔으며(‘테크놀로지’), 동료, 지도교수 및 보조교사의 도움을 통해 학생들과 원활한 소통방법을 터득했다고 했다(‘Community’). 즉, 예비교사들이 느낀 성취감과 온라인 교육실습의 효과는 매우 컸으며, 이는 곧 CONTACTED 모형이 실습에 적합했고 원격교육 역량 강화에도 성공적이었음을 입증해준다. 연구의 한계점 및 시사점도 함께 제시되어 있다.
