The purpose of this research is to inspect students' understing level and to get basic information to build proper teaching and learning strategies to meet students' different perception levels on their grades about light and shadow, which is very closely related to out usual lives. For this research, 125 students offour classes from 3rd grade to 6grade(one class per each grade) were randomly chosen. The questionaire was consist of 10 questions and each question have picture explaining the situation. Students could choose the numbers of right answers for questions. It was composed of the questions to get information for students' perception about a light source(a straight drive of light), the sizes of shadow in accordance with parallel light or divergent light, the sizes of shadow according to the solar height, the sizes of shadow in accordance to the locations of two kinds of light source-those of parallel and divergent light. The result is as followings. First, 6th grade students had the highest understanding level for concept about light and shadow and meaningful differences with 3rd, 4th and 5th grade students. Second, 3rd and 6th grade students understood right about a straight drive of light. Third, about the sizes of shadow made from parallel light driving slantly, 3rd grade students answered light more than any other grade students. About slant light, 6th grade students showed higher understanding but students of every grade showed low understanding(lower than 50%) about shadow made by straight light just above their heads. Sixth, about the sizes of shadow by the location of parallel light, lower than 18% of students of each grade answer right. On the other hand, about those of shadow by the divergent light, approximately 50% of students of each grade answered right and for 3rd grade students, 68%. Seventh, the curriculum of school play a very important role for students' concept perception. The more students made experiments and had experiences, the more right they answered. But they didn't answer right if they didn't have chances to learn at school, although they experiences often in their daily lives. And also, even though they studied in their 3rd grade classes, they were forgetting when they didn't have chances to study continually. When they were in 6th grade and study about light and shadow again, they recalled what they learned and got know more exactly and more extensively. These propose as followings. ⑴ We need to develop many methods to understand light sources and to make experiments to find out principles for how shadows were made by various light sources. They will make students apply the principle to the phenomenon which they observe in their daily lives. ⑵ We need to develop the methods to minimize students' losing memory.

The purpose of this study is to examine the influence of the relative effect of after-school learning activities and psychological variables on middle school students' academic underachievement. To this end, the basic achievement level of Korean, English, mathematics, social studies and science, evaluated in 2011 by the Korea Institute for Curriculum and Evaluation, was set to the dependent variable and after-school activities such as after-school, homework, public online learning and private education and psychological variables such as self-regulated learning ability and career development competency were set as the independent variables. 1,273 middle school students screened under free-lunch support rate were selected by considering the SES level. Hierarchical logistic regression analysis was performed and the collected data were analyzed in order to identify the most significant factor predicting academic underachievement after controlling the impact of the private tutoring. Findings showed that homeworking hour was the most significant predictor for underachievement in all subject areas after controlling the impact of private tutoring. In addition, self-regulated learning ability was significant predicting underachievement after controlling afterschool learning activities including private tutoring. Suggestions were discussed on educational support and academic counseling strategies for underachieving middle school students. 본 연구의 목적은 중학생의 학습부진에 영향을 미치는 방과후 학습활동 및 심리적 변인들의 상대적 영향력을 검증하는데 있다. 이를 위하여 한국교육과정평가원 2011년도 학업성취 진단평가자료를 적용하여 국어, 영어, 수학, 사회, 과학 기초학력수준의 도달여부를 종속변인으로 설정하였으며, 방과후학교, 학교숙제, 공용온라인학습, 사교육 등의 방과후 학습활동 변인과 자기조절학습능력, 진로개발역량 등의 심리적 변인을 독립변인으로 설정하였다. 연구대상으로는 서울시 소재 중학교 가운데 사회경제적 수준을 고려하여 중식지원 비율을 근거로 상, 중, 하에 해당하는 학교 수를 유사하게 구성하여 총 10개 학교를 선정하고 이들 학교에서 1,273명의 학생을 대상으로 설문조사를 실시하였다. 수집된 자료는 위계적 로지스틱 회귀분석을 실시하여 교과별 기초학력수준의 도달여부에 대하여 사교육 학습활동 투입시간의 영향을 통제한 후에 방과후학교, 학교숙제, 공용온라인학습 등의 방과후 학습활동 투입시간과 진로개발역량, 자기조절학습능력 등 심리적 변인들의 상대적 영향력을 확인하였다. 연구결과는 모든 교과목에서 사교육 학습활동 투입시간의 영향을 통제한 후에는 방과후학교, 학교숙제, 공용온라인학습 등 방과후 학습활동 중 학교숙제 학습활동 투입시간이 길수록 기초학력수준에 도달할 가능성이 커지는 것으로 나타났다. 또한, 사교육을 포함한 방과후 학습활동 변인을 통제한 후에는 심리적 변인 중 자기조절학습능력만이 기초학력수준 도달에 유의미한 영향력을 미치는 변인으로 나타났다. 논의에서는 본 연구의 결과를 바탕으로 중학생 학습부진에 대한 교육적 지원 및 학업상담전략에 대하여 제안하였다.

The purpose of this study is to find out the influence on age from 20 to 39 years old women's abdominal size lose effect in weight by using the Aroma and Ultrasonic Wave ·Low-frequency instrument. Twenty-eight adult women whose BMI(Body Mass Index) is above 24kg/㎡ and use S Esthetic salon were selected as the subject of this study for this research from January 5 to March 20, 2005. And they were divided into two random sample groups and the experiments were separately performed to compare and measure the effect of using the Aroma and Ultra Sound·Low-frequency instrument. Before of the survey, informations and data of their general characteristics(age, weight, height, married, job, etc), and food attitude and food habit, exercise habit of the two groups were collected with questionary papers. Group 1 was the group which had used Aroma oil and Ultra Sound·Low-frequency instrument. Whereas Group 2 was the group that had used the Aroma oil only. Both two groups were applied with the application of food attitude and exercise habit on this research. The results of the study were as follows; After 10 weeks, on their waist circumference of the Group 1 and the Group 2 decrease by 8.93cm and 5.94cm. This indicates that the group using Aroma oil and Ultra Sound·Low-frequency instrument reduces more than the group using Aroma oil only(p<0.001, p<0.001). Group 1 and Group 2 lose weight 8.22kg and 5.01kg in 10 weeks. This indicates that the group using Aroma oil and the Ultra Sound·Low-frequency instrument reduces more than the group using Aroma oil only(p<0.001).

목적: sarcopeina는 노화 과정으로 골격근육의 퇴행으로 인한 골격근량이 감소하는 상태이다. 만성 호흡기 질환자에서 호흡근의 강도는 폐기능과 밀접한 연관이 있다고 알려져 있다. 본 연구는 검진 받은 수검자를 대상으로 sarcoepnia가 연속적으로 측정한 폐기능과 관련성을 보이는지 확인하고자 하였다. 방법: 서울대학교 병원 강남센터에서 2012년 체질량 분석 및 폐기능 검사를 포함한 검진을 시행하고 2016년 폐기능 검사를 연속적으로 추적하여 시행한 자들을 대상으로 하였다. Sarcopenia의 기준은 ASM/Height^2의 값이 남성은 7.09Kg/m2, 여성은 5.27Kg/m2 이하일 때로 정의하였다. 성적: 총 2,038 명의 수검자들이 분석 대상이 되었으며 이들 중 161명에서 sarcopenia 기준을 만족하였다. Sarcopenia 가 있는 군은 2012년 폐기능 검사에서 FEV1 은 2.88 ± 0.67L 로 대조군의 3.12 ± 0.69L (P <0.01) 에 비해 유의하게 떨어져 있었다. 년당 FEV1 감소 속도를 보았을 때 Sarcoepnia 군은 0.07 ± 0.41 ml/year , 대조군은 0.07 ± 0.05 ml/year 로 유의한 차이는 없었지만 (P=0.436), BMI로 보정하였을 때 Sarcopenia 군이 BMI 가 25Kg/m2 이상인 비만이 동반된 경우 대조군에 비해 매년 0.011ml/year 씩 유의하게 폐기능이 감소하였다. (P=0.003). 결론: 비만이 동반된 Sarcopenia 가 있는 경우 폐기능 감소가 유의하게 증가하였다.

The purpose of this study was to examine the effectiveness of the college career course which was developed and delivered at one university in Seoul. The differences in the levels of career identity, career decision self-efficacy, career preparation behavior before and after the career course were analysed. The participants of this study were recruited at the beginning of the semester among the students enrolled in the 2009 spring term. The participants were 43 students who took the career course and 39 students who did not take that course. The major findings of this study are as follows. The levels of career identity, career decision self-efficacy, career preparation behavior were significantly different between the two groups after taking the course. This consequence means college career course can use by facilitating method career development for college students. 본 연구의 목적은 대학교에서 개설하고 있는 진로지도 교과목 운영이 수강 여부에 따라 진로 정체감, 진로결정 자기효능감, 진로준비행동에 효과가 있는지를 밝히는 것이다. 연구대상은 서울지역 4년제 대학에서 2009학년도 1학기에 교양과목으로 개설된 진로지도 교과목을 수강한 학생 43명과 수강하지 않은 학생 39명 총 82명(남자 47명, 여자 35명)이며, 연구도구는 진로정체감검사, 진로결정 자기효능감검사, 진로준비행동검사이다. 수업 실시 후 두 집단의 차이에 대한 분석 결과 진로정체감, 진로결정 자기효능감, 진로준비행동 모두에서 통계적으로 유의미한 차이가 나타났다. 이 결과는 진로지도 교과목 운영이 대학생의 진로발달 촉진의 수단으로서 유용하게 활용될 수 있음을 의미한다.
