Augmented reality is a novel human-machine interaction that overlays virtual computer-generated information on a real world environment. It has found good potential applications in many fields, such as training, surgery, entertainment, maintenance, assembly, product design and other manufacturing operations. In this study, a smartphone-based augmented reality system was developed for the purpose of monitoring and managing injection molding production lines. Required management items were drawn from a management content analysis, and then the items were divided into two broad management categories: line management and equipment management. Effective work management was enabled by providing those working on the shop floor with management content information combined with the actual images of an injection molding production line through augmented reality.

Purpose: The purpose of the study was to investigate the core competency and educational needs of paramedic students in disaster management. Methods: A self-reported questionnaire was completed by 207 paramedic students between June 1 and October 29, 2017. The study instrument included disaster preparedness (15 items), disaster management core competency (26 items), disaster education needs (26 items). Data were analyzed using t-test, ANOVA, and Duncan's multiple range test using IBM SPSS 24.0. Results: The students reported that only 13% had experienced or witnessed disasters; however, 95.2% would be willing to help in the event of a disaster. Their disaster preparedness was 1.84 points on a 3-point scale. We did see differences in disaster preparedness by background: hospital practice (F=5.352, p=.001); fire-fighting practice (F=8.994, p=.000). The students had a core competency of disaster management at 3.25 points on a 5-point scale with differences depending on major satisfaction (F=3.760, p=.006). The level of student demands for disaster education was 4.29 points. Conclusion: If variety of educational environments are provided for disaster-related learning and training, the core competency of disaster management for paramedic students will improve. The students will be available as disaster management experts in various fields, even after graduation.

Purpose: The study was conducted to develop the Nursing Practice Capacity scale for evaluating achievement of education objectives among students in nursing school. Methods: This was a methodological study. The scale development process included generation of initial items, verification of content validity, selections of secondary items, preliminary study, and extraction of final items. The participants were five graduates 1 to 4 years after graduation (for the preliminary study) and 125 graduates 1 to 4 years after graduation from the nursing school at A University, South Korea. Item analysis, criterion validity, and internal consistency were used to analyze the data. Results: Twenty-six items were selected for the final scale. The scores on the scale were significantly correlated with the Nursing Competency Scale(r=.62, p<.001) and Nursing Performance Scale(r=.63, p<.001). Chronbach's alpha coefficient for the 26 items was .87. Conclusion: The Nursing Practice Capacity scale for evaluating achievement of nursing education objectives has good validity and reliability. The measurement scale can be useful for evaluating the nursing practice capacity of nurses as well as measuring the extent to which graduates have achieved the established education objectives in the education fields.

Recommender systems, which predict and recommend items that may possibly draw users' interests, have been applied in various fields as e-commerce systems are widespread. Collaborative filtering, one of the major methodologies of recommender systems, recommends either items similar to those preferred by the user, or items preferred by the other similar user. Therefore, two problems determine its performance; one is correct estimation of similarity and the other is predicting the real rating of the recommended item. This study addresses the latter problem. Previous studies predict the real rating based on the mean of the ratings, but this study proposes a prediction based on the range of the ratings and investigates its performance through experiments. As a result, it is demonstrated that the proposed method improves the mean absolute error significantly, compared to the previous method.

Associations, as specific forms of knowledge, reflect relationships among items in databases, and have been widely studied in the fields of knowledge discovery and data mining. Recent years have witnessed many efforts on discovering fuzzy associations, aimed at coping with fuzziness in knowledge representation and decision support processes. This paper focuses on associations of three kinds, namely, association rules, functional dependencies and pattern associations, and overviews major fuzzy logic extensions accordingly.

Police crime statistics report that residential housing such as apartment, low rise, detached houses is the second most vulnerable to crime, which is closely followed by the number of street crimes. Also residential houses are often exposed to quality-of-life crime, e.g burglary. It threatens the basic human rights of house residents in terms of safety and comfort within the urban living environment. This study examines related precedent studies regarding the vulnerability of residential housing including studios, multi-family housing from the viewpoint of crime prevention through environment design(CPTED), extracted the elements and items suitable for the safety of residential facilities and the certification evaluation indicators and check items to be the basis for the checklist are derived. Based on these evaluation indicators and inspection items, we conducted on-site surveys of residential facilities in three areas of Seoul, Yongin and Asan, and the final draft of the checklist was revised based on the results of the field survey. There are 43 items on the 7 fields of evaluation in the final version of checklist, 11 items in the management and operation, 20 items in the surveillance, 7 items in the access control, 1 item in the territoriality, 2 items in the activity support, and 2 items in the security and safety facilities. In addition, various points of interest were added to allow the administrator of the residential facility to earn points for special measures taken for safety. This checklist can be appropriately modified and utilized in consideration of the characteristics of each facility. Korean national police agency has CPOs to check the residential facilities in their jurisdiction using checklists and to certify excellent facilities with high level of safety.

The purpose of this study was to investigate engineering professors' perceptions on the key competencies for engineering students (i.e. creativity, problem solving, designing, field application, etc.) and their instructional efforts to promote the competencies. The guiding research questions included 1) to what extent engineering professors perceived the key competencies as the important qualification that engineering students should obtain in college, 2) to what extent the professors put in a great deal of effort to promote such competencies in their teaching, and 3) how their perceptions on the key competencies correlated with their instructional practice. Two hundred fifteen engineering professors affiliated to diverse fields voluntarily participated in the study and filled out 5 point-Likert scale survey items. In results, despite of some range of variation on their perceptions according to the fields, most of the engineering professors highly valued the four key competencies. However, compared to the perceptions, engineering professors in some engineering fields relatively less focused on promoting the competencies in their teaching practice.

This research is for acquiring implications to science education based on learner's characteristics by analyzing the relationship between contents on science learning and cognitive domain of students in elementary schools through TIMSS 2011-based academic achievement test. Forty one multiple choice items from by TIMSS 2011 were used on 317 primary school students, fourth to sixth grade, and according to grade and achievement level of research targets, test results were analyzed. With these data, the relationship between contents on science learning and the score by cognitive domains, and through correlation by items, we drew static and negative correlations, and then compared the value. The result are as follows: First, other fields except for 'physical science' and 'inference' revealed meaningful differences by learners' grade, and the interrelationship between all contents domains and cognitive fields also appeared statically different. Second, both achievement level of contents and cognition of learners presented significant differences, but the correlation between scientific contents and cognitive field of learners showed different aspects. Third, in static and negative correlation by items, the complexity and their aspects could be classified by targets' academic achievement levels.
