정경아,김봉환,Jung, Kyung-A,Kim, Bong-Whan 한국디지털정책학회 2015 디지털융복합연구 Vol.13 No.2

본 연구는 청소년의 스마트폰 중독수준에 따른 자아탄력성과 부모양육태도 불일치의 차이를 알아봄으로써, 자아탄력성과 부모양육태도의 일치성이 청소년의 스마트폰 중독을 예방하는 데 있어 중요한 요인이 됨을 밝히고자 하였다. 이를 위해 317명의 중, 고등학생을 대상으로 스마트폰 중독 척도, 자아탄력성 척도, 부모양육태도 척도를 실시하여 분석하였고, 연구결과는 다음과 같다. 첫째, 연구대상자들의 스마트폰 중독 수준은 고위험 사용자군 17명(5.3%), 잠재적 위험 사용자군 50명(15.8%), 일반 사용자군 250명(78.9%)으로 나타나, 스마트폰 중독 위험군이 21.1%로 나타났다. 둘째, 스마트폰 고위험 사용자군은 잠재적 위험 사용자군과 일반 사용자군에 비해 자아탄력성 점수가 유의미하게 낮은 것으로 나타났고, 일반 사용자군에 비해 부모 양육태도 불일치 점수가 유의미하게 높은 것으로 나타났다. 이상의 연구결과는, 개인요인인 자아탄력성과 가정환경요인인 부모 양육태도 불일치가 청소년들의 스마트폰 중독과 관련이 높음을 보여주는 것으로서, 자아탄력성을 높이고 부모가 일치된 태도로 자녀를 양육하는 것이 청소년들의 스마트폰 중독을 예방하고 치료하기 위한 하나의 방안이 될 수 있음을 시사한다. This study investigated the differences of the ego-resilience and disagreement in parents' rearing attitude according to the levels of the smartphone addiction of adolescents. To conduct this study, 317 adolescents participated in the survey. The major findings of the study was as follows: First, the smartphone addiction rate was 21.1%, which the high risk group rate was 5.3% and potential risk group rate was 15.8%. Second, ego-resilience was indicated to be lower in the high risk user group than the potential risk user group and the general user group, and disagreement in parents' rearing attitude was indicated to be higher in the high risk user group than the general user group, thereby having indicated to have statistically significant difference. The results of this study, it could be known that ego-resilience and agreement of parents' rearing attitude was significant factors to prevent smartphone addiction of adolescents.

이 연구는 예비교사의 실습지도 능력을 향상시키기 위하여 문제중심학습(PBL)을 적용하여 효과를 분석하였다. 본 연구에서 예비교사들이 해결해야 할 문제는 건강한 간식 만들기 실습을 구안하고, 실습수업을 위한 계획을 세워 직접 실행해보고 그에 적합한 지도안을 작성하는 것이다. 수업은 1) 문제제시 및 확인 2) 문제해결을 위한 자료 수집 3) 문제 해결안 도출 4) 실습진행 5) 문제해결안 수정 6) 결과 발표로 진행하였다. 연구대상자는 C 교육대학교 3학년 학생 중 초등 실과교육 과목을 수강하는 학생 154명이다. 창의적 문제해결력, 자기효능감, 수업만족도 등에 대하여 통계적 검증을 진행하였다. 연구결과 예비교사의 창의적 문제해결력과 교사효능감은 Paired t-test 결과 통계적으로 유의미한 차이가 나타났으며(P<.001), 수업 만족도는 4.7로 높은 편으로 나타났다. 예비교사의 문제중심학습에 대한 성찰지를 분석한 결과를 살펴보면 첫째, 문제중심학습을 진행하면서 교사로서 실습수업에 대한 이해도가 높아졌다. 둘째, 비대면과 대면으로 진행된 조별활동을 통해서 의사소통 및 배려의 역량을 기를 수 있었다. 셋째, 교사에게 주어진 문제를 해결하는 역량을 기를 수 있었던 것으로 나타났다. This study analyzed the effectiveness of applying problem-based learning to improve the practice guidance ability of pre-service teachers. The problem that pre-service teachers need to solve in this study is to devise a healthy snack cooking practice, make a plan for the practice class, implement it themselves, and prepare a suitable guidance plan. Classes were conducted by 1) presenting and confirming problems 2) collecting information for problem solving 3) deriving problem solving plans 4) conducting practice 5) revising problem solving 6) presenting results. This study used the one group pretest and posttest design, sampling 156 students who were in the 3rd grade of C University of Education. Statistical verification was conducted on creative problem-solving skills, self-efficacy and class satisfaction. As a result of the study, there was a statistically significant difference in the creative problem-solving ability and self-efficacy of pre-service teachers(P<.001), and the class satisfaction was high at 4.7. The results of analyzing the reflection papers on problem-based learning of pre-service teachers show that, first, the understanding of practical classes as teachers increased while conducting problem-based learning. Second, it was possible to develop the ability to communicate and be considerate through non-face-to-face group activities. Third, it was found that it was possible for teachers to develop the ability to solve problems given to them.

정경아(Kyung Ah Jung),윤진(Jin Yoon) 한국조리학회 2012 한국조리학회지 Vol.18 No.5

This study was conducted to investigate the relationships between dietary habits and food intake and impulsiveness and aggression in the 6th grade students(boys 53, girls 37, N=100) of the elementary school in Chuncheon area. The main results are as follows. According to the survey on dietary habits and foods intake, the score of I eat a balanced diet that consists of boiled rice, soup, and more than two side dishes was the highest as 4.31±0.96 while the score of I watch TV or read a book during having a meal. was the lowest as 3.16±1.36. The girls had better score than boys for I eat slowly. while the boys had better score than girls for I exercise every day.(p<0.01). Total scores of dietary habits were not significantly different between the sexes. For having fruits, girls(4.28±0.77) ate them more frequently than boys did(3.81±1.02) but for having soda drinks, boys(2.85±1.10) drank more frequently than girls did(2.32±1.11) (p<0.05). The total scores of impulsiveness were not significantly different between the sexes(boys 2.60±0.93 vs. girls 2.57±0.99), but those of aggression were significantly different(p<0.05) between the boys(3.01±0.79) and the girls(2.63±0.78). The score of total dietary habits had a negative relationship with that of aggression(r=-0279, p<0.01) but not with that of impulsiveness. The frequency of ``having milk and milk products`` and all processed foods had positive relationships with the scores of impulsiveness and aggression(p<0.01). Especially, the total score of having processed foods had highly positive relationships with impulsiveness(r=0.656, p<0.01) and aggression(r=0.614, p<0.01). In conclusion, it is very important to have a good dietary habits and to reduce the frequency of having processed foods for children`s good personality.

정경아(Kyung-A Jung),김봉환(Bong-Whan Kim) 한국산학기술학회 2015 한국산학기술학회 학술대회 Vol.2015 No.1

본 연구에서는 청소년들의 스마트폰 중독 수준을 고위험 사용자군, 잠재적 위험 사용자군, 일반 사용자군으로 분류하여 자아탄력성과 부모양육태도 불일치의 차이를 살펴보았다. 연구결과, 스마트폰 고위험 사용자군이 자아탄력성 점수는 가장 낮게, 부모 양육태도 불일치 점수는 가장 높게 나타나, 다른 그룹들과 통계적으로 유의미한 차이를 보였다. 이상의 결과는, 자아탄력성과 부모 양육태도 불일치는 청소년들의 스마트폰 중독과 관련이 높음을 보여주었고, 이에 청소년들의 스마트폰 중독을 예방하기 위해 자아탄력성을 높이고 부모 양육태도를 일치시키는 것이 중요함을 시사해 주었다.

This study was conducted to investigate the state of cooking activities at home and at school among the elementary school 6th graders in Gyeongbuk province. For ``interest in cooking``, 86.9% of the subjects answered ``very interested,`` and the answers were significantly different according to sex(male 45.6%, female 77.8%, p<0.01). Above 70.0% of the subjects answered that they could cook by themselves and the responses were significantly different according to sex(male 35.3%, female 66.7%, p<0.01). The children had experiences of chopping(64.8%), slicing round(62.3%), cutting dice(62.3%), cutting julienne(53.3%), cutting diagonally(45.1%), slicing semicircle(34.4%), and cutting paysanne(22.1%). 93.4% of the subjects had cooking experience at home and most parents(95.1%) were positive to children`s cooking at home. The reasons for cooking at home were ``like to cook``(55.3%), ``to satisfy hunger``(17.5%), ``to eat foods that I want``(14.0%), etc. The only 10.7% of the subjects answered ``difficult`` or ``very difficult`` for the cooking classes at school. The 62.3% of the subjects have cooked the foods again at home that they learned at school, and the responses were significantly different according to sex(p<0.05). The foods that the children wanted to cook at school were pizza, spaghetti, Tteokbokki, hamburgers, etc. The children answered that they had difficulties in ``seasoning``(34.4%) and ``cleaning up after cooking``(21.5%). What the children wished about the cooking class of their schools included ``to cook more often``(35.8%), ``to cook more diverse foods``(29.7%), ``to have the school equipped with cooking tools and facilities``(14.8%), etc. Therefore, the cooking classes for the elementary school students need to be planned considering these results about children`s cooking abilities, skills and demands.

The safety of human exposure to an ever increasing number and diversity of electromagnetic field (EMF) sources both at work and at home has clearly become a public health issue. To date many in vivo and in vitro studies revealed that EMF exposure can alter cellular metabolism, endocrine function, immune activity, reproductive function, and fetal development in animal system. The major parameters found to be altered in cells or individuals following EMF exposure include an increase of free radicals, DNA damage, cancer risk, developmental defect, and reproductive dysfunctions. Epidemiological studies reported EMF can increase life threatening illnesses such as leukemia, brain cancer, amyotrophic lateral sclerosis, clinical depression, suicide, and Alzheimer`s disease has been identified. These effects of EMF exposure differ according to duration of exposure, frequency of waves, and strength (energy) of EMF. In the present review, we briefly introduced the physical properties of EMF and summarized the effect of EMF on human and wildlife animals according to types of EMF, duration of exposure at cellular and organism levels.
