  • 선다형 문제의 경우 특정 위치의 답을 선호하는 수험생의 응답경향이 시험 결과에 미치는 영향을 최소화하기 위하여 정답배열을 특정위치에 편중되지 않고 고르게 분포할 필요가 있다. 이는 정답배열이 특정 번호에 편중되어 있으면 정답을 모를 때 중앙 또는 외곽 번호에 응답경향이 있는 수험생이 추측으로 문항의 답을 맞힐 수 있으므로 시험점수가 학생의 능력을 제대로 반영하지 못하는 결과를 초래할 수 있기 때문이다. 본 논문에서는 2017학년도 대학수학능력시험의 영역별 정답배열에 대하여 Bartels rank test, Wald-Wolfowitz runs test, turning point test, Cox Stuart trend test, difference sign test, Mann-Kendall rank test 등을 실시하여 정답배열이 고르게 분포되었는지 확인하였다. 또한 정답 번호와 배점 사이에 독립성이 지켜지지 않을 경우에도 특정 번호를 정답으로 선호하는 경향을 가진 수험생의 점수는 학생의 능력을 제대로 반영하지 못할 수 있기 때문에 정답의 위치와 배점 사이의 독립성 검정을 추가로 실시하였다.

  • This study was aimed at finding what effects pro-con discussion classes have on students' environmental decisions and set a series of research questions as follows. First, in a small group discussion, how a student's environmental decision is affected by opinions of other students in the same group. Second, what would be the relations between a students' personal factors including gender, environmental knowledge, attitude, and behavior and their decisions. A decisional experiment was applied to 185 students consisting of 2 girl classes and 4 boy classes of K highschool located in Kongju City, Chungnam. These students were taking 'Ecology and Environment' as one of the few general selective subjects once a week. Decision issue introduced to the experiment was regarding of constructing a wind power station on Baekdu Mountains which is protected by the law. This issue can be characterized as not conflict between conservation and development but conflict between two different types of environment friendly approaches that make students experience more difficult while making a decision. The results of this study an be summarized as follows. First, after taking the class introducing environmental issues and having a debate other students on the issue both within a small group or all classmates together, just less then 30% of the students changed their selections. Second, students were found to be affected by other students' opinion while making his or her own decision. Third, no relationship was found to be statistically considerable between students decisions and their personal factors except of their courses, liberal or science.

  • Background: The C-arm fluoroscope is known as the most important equipment in pain interventions. This study was conducted to investigate the completion rate of education on radiation safety, the knowledge of radiation exposure, the use of radiation protection, and so on. Methods: Unsigned questionnaires were collected from the 27 pain physicians who applied for the final test to become an expert in pain medicine in 2011. The survey was composed of 12 questions about the position of the hospital, the kind of hospital, the use of C-arm fluoroscopy, radiation safety education, knowledge of annual permissible radiation dose, use of radiation protection, and efforts to reduce radiation exposure. Results: In this study, although most respondents (93%) had used C-arm fluoroscopy, only 33% of the physicians completed radiation safety education. Even though nine (33%) had received education on radiation safety, none of the physicians knew the annual permissible radiation dose. In comparing the radiation safety education group and the no-education group, the rate of wearing radiation-protective glasses or goggles and the use of radiation badges or dosimeters were significantly higher in the education group. However, in the use of other protective equipment, knowledge of radiation safety, and efforts to reduce radiation exposure, there were no statistical differences between the two groups. Conclusions: The respondents knew very little about radiation safety and had low interest in their radiation exposure. To make the use of fluoroscopy safer, additional education, as well as attention to and knowledge of practices of radiation safety are required for pain physicians.

  • The purpose of this study is to analyze the research trends about the child care center accreditation system in Korea which has been practiced relatively recently. To solve the research problems, 68 pieces of master's theses, doctoral dissertations, and journal articles were analyzed. The results of this study are as follows: First, since 2005 when the research about the child care center accreditation system was first applied, the number of research has increased dramatically over the year 2006 and 2007. Also, majority of the research was done mostly in the region of Seoul and Gyeonggi-do compared to other regions. Second, the child care center accreditation system administration was the most frequently researched topic, followed by the evaluation on the child care center accreditation system, and the general understanding and recognition of the child care center accreditation system. Third, quantitative method was used most frequently to research the child care center accreditation system, and literature review and qualitative method were used relatively less. Most of the research subjects were the child care center directors and teachers. The sample size of the research was relatively big, and most of the survey were either made by the researcher or were modified and adjusted from the previously used survey questions according to the present research. Most of the data analysis of quantitative study were done with descriptive statistics, and with t-test, chi-square, and ANOVA and there was only one done with correlation analysis.

  • 현재까지 존재하는 무수한 악성 행위에 대응하기 위해서 다양한 기법들이 제안되었다 그러나 현존하는 악성행위 탐지 기법들은 기존의 행위에 대한 변종들과 새로운 형태의 악성행위에 대해서 적시 적절하게 대응하지 못하였고 긍정 오류(false positive)와 틀린 부정(negative false) 등을 해결하지 못한 한계점을 가지고 있다. 위와 같은 문제점을 개선하고자 한다. 여기서는 소스코드의 기본 단위(token)들을 개념화하여 악성행위 탐지에 응용하고자 한다. 악성 코드를 개념 그래프로 정의할 수 있고, 정의된 그래프를 통하여 정규화 표현으로 바꿔서 코드 내 악성행위 유사관계를 비교할 수 있다. 따라서 본 논문에서는, 소스코드를 개념 그래프화하는 방법을 제시하며, 정확한 악성행위 판별을 위한 유사도 측정방안을 제시한다. 실험결과, 향상된 악성 코드 탐지율을 얻었다.

  • This study examined the experience of administrators of home-based child care centers about CCFSM (Center for Children's Foodservice Management) service using a qualitative approach. Eight administrators of home-based child care centers in Seoul with more than one year's experience of CCFSM were interviewed regarding their opinions on support activities, standards, and foodservice management. The interviews were semi-structured with open-ended questions and they were transcribed and classified according to the subjects. There were negative opinions regarding the indications after a hygiene inspection leaving photographs or records behind, but most positive opinions were about round visits for foodservice sanitation and nutrition management. The participants thought that it is not enough that the number of nutrition education sessions for children be twice a year, and there was a suggestion to increase the rentals of nutrition educational materials. There was a complaint about the menus in that were difficult to prepare for lunch time or to obtain food ingredients for. The administrators poorly recognized how to use the standardized recipes and chlorine-based disinfectants, so they could not be applied properly. They also pointed out the problems of joint purchasing as low quality and high prices in the food service operation. They felt discriminated against compared to with larger scale child care centers because of their size and expressed concerns regarding the fact that many home-based child care centers were not included due to the lack of publicity and budget. Through the results, the CCFSM should provide a differentiated service and management by creating a dedicated team or staff for home-based child care centers so they will not feel left out. In addition, It is also important to constantly gather opinions to improve the menus and to use standardized recipes practically. In addition, it will be necessary to develop nutrition educational materials corresponding to the infants' age for home-based child care centers and increase the rent to expand nutrition education.

  • This study is to propose an 'education-training-certificate of qualification' design of fashion accessories production, which can be applied to education in universities and individuals. It is based on the National Competency Standards (NCS), which was developed through the '2013 National Competency Standards Development Project' for the fashion accessories production. FGI (Focus Group Interviews), which is a research methodology, is carried out on target groups of educational experts and specialists in the field of fashion accessories production. Through this, five courses were suggested; first, 'fashion accessories design' course was proposed for the education and training of 'design development' and 'development of raw materials'. Secondly, 'fashion product production' course was proposed for the education and training of 'production of samples'. Thirdly, 'fashion product manufacture and planning' course was proposed for the competency element units: 'calculation of cost', 'determination of mass production model and price', 'planning of the main manufacturing process' and 'ordering of raw materials'. Lastly, 'mass production of fashion products' course and the 'field practice of fashion product manufacture' course were proposed for the competency element units: 'planning for mass production', 'preparation for mass production', 'mass production' and 'inspection of completed products'. In addition, a new certificate of 'technician of fashion accessory production' was proposed in order to test qualified skills for the fashion accessories production. The test is composed of a written examination of short-answer questions, technical drawing and production.
