이 연구에서는 2009 개정 교육과정에 따른 고등학교 융합형 '과학' 교과에서 사용된 선다형 평가 문항의 특성을 분석하였다. 문항의 출제 경향을 분석하기 위해 융합형 교과에 특이적인 분석틀을 구안하여 분석하였으며, 문항 반응 이론을 적용하여 문항의 특성을 양적으로 분석하였다. 문항의 출제 경향 분석 결과, 문항 출처, 융합 범위, 인지 수준 측면에서 융합형 '과학' 교과의 취지를 제대로 반영하고 있지 못하는 것으로 나타났으며, 기존 교육과정의 과학 교과와 같은 분과적 교수-학습 및 평가가 이루어지고 있음을 알 수 있었다. 문항 반응 이론을 적용한 분석 결과, 대체로 문항의 난이도는 적절하며, 변별도는 높은 수준인 것으로 나타났다. 하지만 분석틀을 구성하는 3개 범주와의 연관성은 나타나지 않았다. 이와 같은 연구 결과를 토대로 융합형 '과학' 교과의 취지를 반영한 교수-학습과 평가를 위한 개선점을 논의하였다.

The purpose of this study is to analyze the brand choice behaviors of male and female college students in their twenties, to examine the differences in their information-searching activity to the type of the behaviors and shopping places for purchasing apparel products. The data were analyzed by Factor analysis, Ouster analysis, one-way ANOVA, Duncan's multiple range test. The results are as follows: 1. With regard to the brand choice behaviors of male and female college students in their twenties, two factors were produced as 'consumers' loyalty to brand' and 'brand switching behavior'. 2. The brand choice behaviors were classified into three groups as 'a brand-switching group', 'a loyalty-to-brand group', and 'an indifferent-to-brand group'. There were significant differences between the groups. 3. The results for demographic differences in terms of the brand choice behaviors showed that there was a significant difference in 'brand switching behaviors' by gender. 4. There were significant differences in the media for information search and the places for shopping apparel products in terms of the brand choice behaviors.

Purpose: This study was performed for the effective management of nursing organization as surveyed choice motives and job satisfaction about nurses who changed to public hospitals. Methods: This study is a descriptive study. This study surveyed 214 nurses who changed jobs to public hospital in six Gyeonggi-do hospitals from October 23 to November 20, 2015. The collected data were analyzed for descriptive statistics, t-test, one-way ANOVA, sheffe test, multiple linear regression analysis using the SPSS/WIN 21.0 program. Results: Most of the nurses chose public hospitals due to benefits correspond to public officials. They had worked in general hospitals located on provinces and changed jobs due to a heavy workload and low benefits. Of the participants 84.1% were satisfied with changing jobs to public hospitals and the advantages of public hospitals of their choice were job stability and good employee benefits(guaranteed maternity and paternity leave, etc). On the other hand there were complaints about low salaries compared to the workload after changing jobs to public hospitals. Conclusion: Hospitals need to enhance job stability and provide nurses with good employee benefits to reduce turnover rate.

The purpose of this study is to determine the patterns of differences between genders in science achievement. Eleventh grade, 140 female and male students were sampled from a school in Seoul. According to the analysis results of pilot study, 20 items were finally selected for the main study. To sharpen our interpretations of the factors and provide some confirmation, we supplemented the statistical analysis with a more detailed cognitive study of the items using think-aloud protocols and interviews with student test takers. The analysis of this study took into account the different item formats, contexts, and presentation styles. The findings are as follows: First, there was no significant gender difference between multiple-choice and open-ended items. Second, male students achieved significantly better in the context of everyday life in multiple-choice items. Third, male students favored items presented as written texts. Fourth, in problem-solving process, female students tend to apply their science concepts, whereas male students tend to apply their everyday experiences. The results of this investigation indicate that gender difference in science achievement depends heavily on item characteristics.

In route guidance systems fastest-path routing has typically been adopted because of its simplicity. However, empirical studies on route choice behavior have shown that drivers use numerous criteria in choosing a route. The objective of this study is to develop computationally efficient algorithms for identifying a manageable subset of the nondominated (i.e. Pareto optimal) paths for real-time vehicle routing which reflect the drivers' preferences and route choice behaviors. We propose two pruning algorithms that reduce the search area based on a context-dependent linear utility function and thus reduce the computation time. The basic notion of the proposed approach is that ⅰ) enumerating all nondominated paths is computationally too expensive, ⅱ) obtaining a stable mathematical representation of the drivers' utility function is theoretically difficult and impractical, and ⅲ) obtaining optimal path given a nonlinear utility function is a NP-hard problem. Consequently, a heuristic two-stage strategy which identifies multiple routes and then select the near-optimal path may be effective and practical. As the first stage, we utilize the relaxation based pruning technique based on an entropy model to recognize and discard most of the nondominated paths that do not reflect the drivers' preference and/or the context-dependency of the preference. In addition, to make sure that paths identified are dissimilar in terms of links used, the number of shared links between routes is limited. We test the proposed algorithms in a large real-life traffic network and show that the algorithms reduce CPU time significantly compared with conventional multi-criteria shortest path algorithms while the attributes of the routes identified reflect drivers' preferences and generic route choice behaviors well.

In this paper, we present a structure of personalized e-Learning system to study for a test formalized by uniform multiple-choice using on/off line mixed estimations as is the case of Driver :s License Test in Korea. Using the system a candidate can study toward the license through the Internet (and/or mobile instruments) within the personalized concept based on IRT(item response theory). The system accurately estimates user's ability parameter and dynamically offers optimal evaluation problems and learning contents according to the estimated ability so that the user can take possession of the license in shorter time. In order to establish the personalized e-Learning concepts, we build up 3 databases and 2 agents in this system. Content DB maintains learning contents for studying toward the license as the shape of objects separated by concept-unit. Item-bank DB manages items with their parameters such as difficulties, discriminations, and guessing factors, which are firmly related to the learning contents in Content DB through the concept of object parameters. User profile DB maintains users' status information, item responses, and ability parameters. With these DB formations, Interface agent processes user ID, password, status information, and various queries generated by learners. In addition, it hooks up user's item response with Selection & Feedback agent. On the other hand, Selection & Feedback agent offers problems and content objects according to the corresponding user's ability parameter, and re-estimates the ability parameter to activate dynamic personalized learning situation and so forth.
