Experiments done in traditional physics laboratories have been criticized for giving too detailed instruction so that student could follow the experimental procedure without understanding. This type of experiment is often called "cookbook experiment." Cookbook experiment was known to be little help to understand the physics concepts and to increase student interest. To solve these problems with traditional cookbook experiment, non-directive introductory physics laboratory was designed and tried with the freshmen of Department of Physics Education of Seoul National University. Non-directive laboratory was characterized by the lack of step by step instruction for students to follow. The instruction students received consisted of the goal of experiment, a short introduction, and a list of suggested materials to be used. Student designed the experimental procedure and decided what material they wanted to use. One group submitted one lab report as a group to encourage cooperation among students. Lab report could be written in any form students wanted and no penalty point was given to poor data or inappropriate theory, etc to encourage taking risks. Penalty points were given if the students did not get involved during class hours. Student received extra point for being creative and / or working hard. Teaching assistants used Socratic dialogue in helping students to find their own way instead of explaining what they had to do. Students' interest about the non-directive experiment was studies at the of the semester. A questionnaire was made for students to answer. The questionnaire consisted of four categories, the equipment and the laboratory, the experimental procedure, the lab report, and teaching assistant. For each category, student were asked to explain the differences from other laboratory classes, features they liked and the reasons why they do, features they did not like and why they did not. At the end of the questionnaire, students were asked what hey wanted to change and what they did not. They also could put any opinion they had other than the questions asked. Student overall opinion was very positive. All the students said they liked the lack of detailed experimental procedure because it gave them the feeling of achievement, made them feel challenged and think in more diverse and creative ways. Students liked the lab report because group report forced them to discuss more and the free form lab report helped them to focus on the what they did. Student responses about the teaching assistant was also positive but not as enthusiastic as the experimental procedure or lab report. However students recognised that the role of the teaching assistant was as a guide, a supporter, or a facilitator.

Purpose: This study aims to analyze the factors affecting the dropout intentions of the dental technology students of a college. Methods: The subject of this study was 76 freshmen and 74 sophomores of dental technician major in an anonymous college. Results from the questionnaire called K-vision diagnosis program were computed by means of t-test, One-Way ANOVA, and correlation analysis. Results: 1. Total points of the drop out intention came to 782.14 points. Of the five categories concerned with the drop out intention, complain in college satisfaction(50.12points) was the highest and department satisfaction(47.51points) was the lowest. Of 16 subcategories, complaining in administrative supporting system proved the highest as 50.80 points and Inquiry to Professor the lowest(45.56 points). 2. Among the general characteristic gender (p<. 01), student group (p<.01), and credit (p<.05) made a meaningful statistical difference; no statistical significance was found in grade, admission, and dwellings. 3. Of the five categories, statistical significance was shown as follows; Department satisfaction (p<.01), College satisfaction (p<.05) under gender, Department satisfaction (p<.05) in grade, Academic integration (p<.01), Department satisfaction (p<.01) in credit. No statistical meaning was found in admission and dwellings. 4. Statistical significance was found under 16 subcategories as follows: Career identification(p<.01), Academic support system(p<.01), Social activity II(p<.05) in gender area, Inquiry to professor(p<.01), Learning(p<.05), Understanding learning I(p<.05) in grade area, Learning(p<.001), Career identification(p<.001), Understanding learning I(p<.01), Understanding learning II(p<.01), Inquiry to professor (p<.01), Learning ability (p<.05), Occupation (p<.05), Social Activity II(p<.05), Administrative support system (p<.05) in student group area, Credit (p<.001), Career identification (p<.01), Understanding learning I(p<.05) in credit area; admission and dwellings was statistically meaningless. 5. Of the 5 categories academic integration (r=.766) was most relevant to the dropout intention of the subjects and followed by department satisfaction (r=.735), college satisfaction (r=.554), service acceptability (r=.373), and statistical significance was shown as p<.01. Conclusion: Considering the results of this study, we are in a pressing need for the introduction of policies and programmes aiming at preventing the dropout rates of the dental technician majors at college. In tandem with this, qualitative and viable human resource management of the dental technicians should be implemented.

본 연구는 조리학과 재학생들의 학과 선택에 따른 블록식 수업프로그램에 대한 만족도와 미래직업의지에 영향적 요인들을 확인하기 위해 변인으로 선택, 성별과 학년으로 구분하여 검증하였다. 이와 함께 블록식 수업 프로그램의 만족도가 미래 직업 의지에 영향을 주는 것에 대해서도 검증을 실시하였다. 연구 결과 성별과 학년별에 따른 수업만족도 T-검증 결과로 볼 때 유의수준 0.05에서 유의성을 보였으며, 남학생들이 여학생들보다 수업만족도가 높은 것으로 나타났다. 성별에 따른 미래 직업 의지에서도 성별에 따라 유의한 차이가 나타났는데, 역시 남학생이 여학생보다 미래 직업의지가 더욱 강하게 나타났다. 그러나 학년별 블록식 수업만족도 검증에서는 학년간 유의한 차이를 보이지 않고 있다. 학년별 미래직업의지에서는 유의수준 0.01에서 유의한 차이를 보이고 있다. 결과적으로 1학년이 가장 강하게 나타났고 4학년이 비교적 약하게 나타났다. 다음으로 선택변인에 따라 블록식 수업프로그램 만족도를 검증한 결과 두 변인 간 상관관계가 존재하고, 유의성검증에서도 모두 p-value가 0.000으로 매우 유의하게 나타났다. 자신이 선택한 결과에 대해서 책임감과 만족도가 높게 나타나는 것은 이미 많은 선행연구에서도 검증이 된바 있으며 블록식 수업에서도 같은 결과를 얻게 된 것이다. 마지막으로 블록식 수업만족도와 미래직업의지와의 관계에서도 p-value 0.000수준으로 유의성이 매우 높게 나타났으며 회귀결정계수도 0.840으로 상당히 크게 나타났다. 따라서 본 연구 결과로 볼때 성별에 따라서 블록식 프로그램의 만족도와 미래직업의지는 차이가 나는 것은 여학생들이 남학생보다 블록식 교육시스템에서 육체적으로 더 힘들게 느끼는 것으로 사료된다. 반면 학년에 따라서 차이는 없지만 미래직업의지에는 차이가 나타났다. 학년에 따른 미래직업의지에서 1학년이 가장 높고 4학년이 가장 낮게 나타났다. 이러한 결과를 볼 때 성별에 따라 블록시스템에 만족도가 다르고 학년에 따라 미래직업의지가 다르기 때문에 조리 교사들은 이러한 결과를 고려해서 학생들의 미래직업 준비와 수업만족도에 대한 개선을 계획해야 할 것이다.

It is important for young adults to establish good dietary behavior for healthy life. The prevalence of obesity in college students has increased gradually. The obesity is one of the most prevalent health problems in S. Korea. Moreover, obesity is closely related with the disease such as cardiovascular disease, diabetes mellitus. The purpose of this study was to evaluate health practice, serum components and nutrient intake of the college students according to Body Mass Index (BMI) level. 400 male and female freshmen students in 4 year university located near to Seoul metropolitan area were surveyed respectively through the health check-up procedure for college entrance in February. Survey was carried out for them by questionnaires, including a 24-hour dietary recall and anthropometric measurements. Blood samples were obtained while fasting. Nutrient intake was expressed by DDS(Dietary Diversity Score by 5 food groups) and DVS(Dietary Variety Score). Nutrition level was analyzed by Can-Pro (Korea Nutrition Association). And for the quantity intake, percentage ratio against daily requirement(by KDRIs) and MAR(Mean Adequacy Ratio) were calculated. Underweight group($BMI<18.5kg/m^2$), normal weight group($18.5) and overweight group($BMI<23.0 kg/m^2$) were 18.5%, 61.2% and 19.3% respectively. Nutrient intake levels and food intake status were not significantly different among three groups. The mean nutrient adequacy ratio (MAR) was not significantly different by BMI status. Nutrient intakes of calcium, iron, and riboflavin were especially low for all the students. Overweight group showed high blood pressure(120.9/79.3 mmHg) compared with the underweight group (116.4/ 75.8mmHg) but the difference was not significant. The serum triglyceride level in overweight group (94,0mg%) was higher than that in normal (70.9mg%) or underweight group(70.8mg%)(p<0.05). HDL-cholesterol level in overweight (43.8 mg%) group was not significantly different from that in underweight group (45.9mg%). BMI was positively correlated with blood pressure, hemoglobin, and the intake of total fat and cholesterol. But it was negatively correlated with HDL-cholesterol level. With these results overweight group is closely related with the cardiovascular disease risks, such as high blood pressure and high triglycerides and cholesterol. Thus, a health intervention program including weight control is required for young adults.

Purpose: To minimize an interruption in chest compression, reduce the hands-off time, the American Heart Association has recommended the ratio of chest compression to ventilation ratio to 30:2 from 2005 CPR guideline to 2010 CPR guideline. However, current studies have shown that the hands-off time was > 10 seconds with that method. For this reason, we devised new CPR method that a ventilation to chest compression ratio of 2:30 to reduce pt assessment time and skipped the assessment step of carotid artery pulse would be a more effective way to reduce the hands-off time & the time to set the CPR. According to the more detailed purpose are listed below. 1) We would like to confirm efficiency of a ventilation to chest compression ratio of 2:30 than a chest compression to ventilation ratio of 30:2 to reduce the hands-off time & the time to set the CPR. 2) We would like to evaluate possibility of increasing for chest compression accuracy of a ventilation to chest compression ratio of 2:30 than a chest compression to ventilation ratio of 30:2 3) We would like to evaluate possibility of increasing for ventilation accuracy of a ventilation to chest compression ratio of 2:30 than a chest compression to ventilation ratio of 30:2 Methods: According to 2005 American Heart Association Guidelines, 60 paramedic students(20 students X freshmen, sophomore, junior) performed 5 cycles of 3~ chest compressions : 2 ventilations after A, B, C evaluation with Laerdal Resusci R Anne SkillReporters. After 5 minutes rest, the 60 students performed 5 cycles of 2 ventilations : 30 chest compressions after A, B evaluation with the manikins between 13 and 17 September 2010. The short reports including speed & accuracy of chest compression, respiratory, CPR cycle were gained from the manikins. Hands-off times were measured by assistants. Results: Recently, the importance of high quality CPR was emphasized in order to perform the CPR faster and more accurate. To find out improving the conventional CPR method, we switch the procedure of the compression and the ventilation. By switching the procedure back and forth, we are able to compare the effectiveness of CPR between two type of CPR method which are 2:30 and 30:2 methods. 2:30 is that the breaths is delivered twice, first and perform 30 compressions while 30:2 perform 30 compressions first and give 2 breaths followed by the ABC method. Also, we verify the effectiveness of the hands off time, compression accuracy of the compression through the comparison of the two procedure as mentioned earlier. Consequently research verified that 2:30 is the efficient by providing faster set up delivering more accurate chest compression. Conclusion: 2:30 can minimize a time delay from cardiac standstill until starting the chest compression. In addition, hands-off time which is an interruption in chest compression can be shortened by 2:30 method, which result to effective oxygenation of coronary artery & maintenance of the bloodstream. Once again, performing the 2:30 method provide lessen hands off time and increase the accuracy of the chest compression.

이 연구는 강원도 고성군 지역에 분포하는 뒤배재 화산체와 서낭바위를 대상으로 화성암 지역의 지형과 지질학습을 위한 야외지질학습장을 개발하는 것이다. 그리고 고등학교 1학년을 대상으로 그 교육적 효과를 알아보았다. 연구절차는 Orion의 모형에 근거하여 준비 단계, 야외학습 단계 및 정리 단계 순이며, 교육과정에 제시된 지질학습 요소를 바탕으로 야외지질학습장을 개발하였다. 야외학습 전에 학생들은 광물, 암석 등에 대하여 단순히 암기하고 있으며, 화강암과 현무암이 분포하는 지형의 형성과정에 대한 이해도는 매우 낮았다. 특히, 화강암과 현무암이 한 마그마에서 동시에 형성되는 것으로 이해하고 있다. 야외학습 후, 학생들은 광물, 암석 및 지질구조 등에 대한 단순한 지식은 학습이 잘 되었으나, 화강암과 현무암의 생성시기를 인식하지 못하여, 두 암석의 지형적 특성을 제대로 설명하지 못하였다. 이유는 중학교에서 화강암과 현무암의 생성과정에 대한 단순한 개념은 학습하였으나, 두 암석이 생성되는 지질시대 차이에 대한 의미는 학습하지 않았기 때문인 것으로 해석된다.

경찰인력의 부족과 사회양극화 현상으로 범죄율이 증가하는 가운데 사경호의 사회적, 직업적 가치가 상승하면서 대학에서도 경호관련분야의 전문 인력을 양성하기 위해 사회적 역할로 주목받고 있다. 그러나 경호관련학과와 학문적 정체성은 여전히 해결해야할 과제로 남아있다. 2000년도에는 경호관련학과를 신설하여 60여개의 대학이 있었으나 현재 신입생 감소 등의 문제로 줄어들어 39개 대학(2년제+4년제)에 관련학과가 설치되어 있는 실정이다. 또한 학과의 명칭은 경찰, 경호, 무도, 부사관을 혼용을 사용하며 사회적 전반적인 시장변화에 대응하고자 적절하게 혼용명칭을 요구되고 있으며, 물론 학과가 추구하는 공통목표는 민간인에 의한 안전서비스 활동이다. 그러나 아직 대학교체계의 확립이 미흡한 것이 실정이며 또한 여러 분야의 교수요원으로 교육과정이 엉성하게 구성되어 있다. 따라서 본 논문에서는 경호산업에 있어서 밀접한 2년제 경호관련학과를 선택하여 현실적인 문제점을 부각하고 각 대학의 교육과정을 비교 분석하여 기본적인 교육과정을 도출하고 앞으로 나아갈 방향을 제시하였다. 경호관련학과들이 가진 공통목표를 지향하면서도 학교별로 흔들리는 교육과정은 경호학 학문이 미 정착된 현실을 반영하고 있으며 앞으로 해결할 과제이다. 경호관련학과는 세분화된 교육을 취함과 동시에 전문인력간의 공동작업의 기회를 제공할 수 있는 방법, 산학협동과정, 산학공동개발 등이 강화된 교육이 되어야할 것이며 산업체의 현장실습 수업을 좀 더 확대, 개편, 강화할 필요성이 대두되며, 학교 간 또는 교수요원들 간의 노력을 통해 해결되어야 할 것이다.
