본 연구는 간호대학생의 전공선택동기가 전공만족도, 대학생활만족도 및 자기주도 학습능력에 미치는 영향력을 확인하기 위해 시행된 서술적 조사연구이다. 본 연구에서는 자가보고식 설문지를 이용하여 2015년 4월 1일부터 15일까지 195명의 간호대학생으로부터 자료를 수집하였으며, Fisher's exact test, t-test, one way ANOVA, Mann Whitney test와 ANCOVA를 이용하여 자료를 분석하였다. 연구 결과 단지 41.5%의 간호대학생 만이 적성 또는 흥미를 이유로 간호학을 선택하였으며, 과반수인 58.5%의 간호대학생이 취업 전망과 고등학교 성적을 이유로 간호학을 선택하였다. 그리고 전공선택동기는 전공만족도(p<.001), 대학생활만족도(p=.008), 자기주도 학습능력(p=.001)에 유의한 영향요인으로 작용하였는데, 적성 또는 흥미로 전공을 선택한 그룹이 취업 전망으로 전공을 선택한 그룹보다 전공만족도 0.25배, 대학생활만족도 0.52배, 자기주도 학습능력 0.26배 높게 나타났다. 본 연구 결과를 바탕으로, 대학 입학 전 중고등학생들의 진로 지도를 위한 보다 전문적인 진로교육프로그램 개발 및 활용과 대학 입학 후 간호대학생의 대학생활 적응을 돕기 위한 전공선택동기에 따른 맞춤형 개별 상담프로그램 및 대학생활 적응 프로그램을 개발 및 적용을 제언하는 바이다.

This study concerns with an applicability of the management science approach to the score adjustment among the College Scholastic Aptitude Test(CSAT) optional subjects. A linear programming model is developed to minimize the sum of score distortions between optional subjects. Based on the analysis of the 377,089 CSAT(2010) applicants' performances in social science test section, this study proposes a new approach for the score equating or linking method of the educational measurement theory. This study makes up for the weak points in the previous linear programming model. First, the model utilize the standard score which we can get. Second, the model includes a goal programming concept which minimizes the gap between the adjusting goal and the result of the adjustment. Third, the objective function of the linear programing is the weighted sum of the score distortion and the number of applicants. Fourth, the model is applied to the score adjustment problem for the whole 11 optional subjects of the social science test section. The suggested linear programming model is a generalization of the multi-tests linking problem. So, the approach is consistent with the measurement theory for the two tests and can be applied to the optional three or more tests which do not have a common anchor test or a common anchor group. The college admission decision with CSAT score can be improved by using the suggested linear programming model.

This research seeks to derive the design rainfalls through the L-moment with the test of homogeneity, independence and outlier of data on annual maximum daily rainfall in 38 Korean rainfall stations. To select the fit appropriate distribution of annual maximum daily rainfall data according to rainfall stations, applied were Generalized Extreme Value (GEV), Generalized Logistic (GLO) and Generalized Pareto (GPA) probability distributions were applied. and their aptness was judged Dusing an L-moment ratio diagram and the Kolmogorov-Smirnov (K-S) test, the aptitude was judged of applied distributions such as GEV, GLO and GPA. The GEV and GLO distributions were selected as the appropriate distributions. Their parameters were estimated Targetingfrom the observed and simulated annual maximum daily rainfalls and using Monte Carlo techniques, the parameters of GEV and GLO selected as suitable distributions were estimated and. dDesign rainfallss were then derived, using the L-moment. Appropriate design rainfalls were suggested by doing a comparative analysis of design rainfall from the GEV and GLO distributions according to rainfall stations.

This paper reports the aging driver traffic accident severity modeling results. For the modeling, Poisson regression approach is applied using the data set obtained from the Korea Transportation Safety Authority's simulator-based driver aptitude test results. The test items include the estimations of moving objects' speed and stopping distance, drivers' multi-task capability, and kinetic depth perception and so on. The resulting model with the response variable of equivalent property damage only(EPDO) indicated that EPDO is significantly influenced by moving objects' speed estimation and drivers' multi-task capabilities. More interestingly, a comparison with the younger driver model revealed that the degradation of such capabilities may result in severer crashes for older drivers as suggested by the higher estimated parameters for the older driver model.

In this study, there are many difficulties in defining and judging creative people because there is no systematic analysis method using accurate standards or numerical values. Analyze and judge whether In the previous study, A study on the application of rule success cases through machine learning algorithm extraction, a case study was conducted to help verify or confirm the psychological personality test and aptitude test. We proposed a solution to a research problem in psychology using machine learning algorithms, Data Mining's Cross Industry Standard Process for Data Mining, and CRISP-DM, which were used in previous studies. After that, this study proposes a solution that helps to judge creative people by applying the feature selection algorithm. In this study, the accuracy was found by using seven feature selection algorithms, and by selecting the feature group classified by the feature selection algorithms, and the result of deriving the classification result with the highest feature obtained through the support vector machine algorithm was obtained.

This study has formed a clear definition of the elements of inquiry skills : inference, determining relationship, causal explanation, prediction, and created the goals of assessment and the items of assessment. They have been checked the validity and the objectivity and the clarity of the items by six professors of science education. At the same time, the two times of the field trial has been executed. and checked the discriminating power and the difficulty index and the effectiveness of distracters, and modified the items. The test developed in this way was administered to 1060 students of the eighth grade, randomly cluster-sampled from the universe, and standardized. The test is the aptitude test as well as the norm-reference test. and has twenty items. The testing-time is thirty minutes. And the cotent validity is 85%, the objectivity of the answer keys 91.7%, the mean of items difficulty 68.8%, the mean of discriminating power 0.39, the standard deviation 3.31, the reliability(K-R 20) 0.69. Because it is the standardized lest, it can diagnose the well-developed skills and the ill-developed skills of the students, and monitor the development of skills.

Purpose - This study attempts a multifaceted analysis utilizing the Chinese test takers' results of the Economy & Business Aptitude Test. Since Chinese students study socialist theories of economics along with market-based ones, comparing Chinese university students' basic knowledge of economics and business and its application to those of Korean test takers is also very meaningful from the perspective of economics education research. Research design, data, and methodology - This study investigates the results on the test of economy and business understanding between Korea and China. For comparison of the result, we conducted MK-TEST for two universities in China. Result - This study finds that the average correct answer rate of Korea is higher than one of China according to the overall results. The average difference rate is about 15% between Korea and China. More concretely, the correct answer rate of business area is higher than one of economy area, identifying them by subject area. Conclusion - According to the results, this study can infer that there are no or little differences in the ability of examinee to solve applied questions between Korea and China and the differences of the scope and emphasis point in an academic curriculum between both countries might bring these kinds of results. Finally, Chinese students shows higher correct answer rate to the questions about the economy issues and policies related to China than one of Korea examinee.

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.
