The purpose of this study is to analyze recently developed tools and relevant literature in order to discuss development scheme of augmented reality-based programming tools targeting elementary school students. Literature review draws conclusion that touch mode in the mobile augmented reality is effective, especially in the environment where manipulates commands and it is required to design contents taking class environment and teaching-learning strategy into account. Such research findings indicate that augmented reality-based programming tools targeting elementary school students should be designed to increase their interest in programming in a way that when physical teaching materials or specific space are recognized, the programmed problems will be augmented to allow students to combine the commands in the augmented environment.

The purpose of this study was to develop and evaluate a measuring scale for the effect of reading programs for children. First, in literature review, the effects and children's reading programs performance scales were analyzed, and then independent variables, dependent variables, and control variables for children's reading achievements were defined. Second, survey questionnaires for children, librarians, program instructors, and heads of child centers were designed to measure dependent variables and control variables on the scale. Third, the questionnaires for children were distributed to 10 public libraries participating in <2013 The Reading with Library> programs for two times in the early and the late time of the programs. Also, the survey questionnaires of 30 librarians, program instructors, and heads of the child centers were carried. Finally, all of the data were collected and analyzed in time series, and the improvements for the scale were proposed.

Recently, interest in online teaching·learning and evaluation tools has increased in the context of Covid-19. In order to use tools effectively, it is necessary to identify the structural influence and causal relationship between the learner's affective and cognitive variables. In this study, to identify a causal relationship between motivation and thinking while using online judge, research and competing model were established and model fit/path analysis were performed. It was found that there was a linear causal relationship from tool usage, self-efficacy, flow, logical thinking, to computational thinking. It was confirmed that 'self-efficacy → flow', or 'flow' had mediating effect on the path from tool usage to thinking, and tool usage was not exerted to thinking through 'flow → self-efficacy'. The causality of 'logical thinking → computational thinking' was identified on the path where tool usage affects thinking ability through learning motivation, but the causality of 'computational thinking → logical thinking' was not identified.

The purpose of this study was to develop a perception of importance on patient safety management scale (PI-PSM) for Hospital Employee. The PI-PSM was developed and vallidated as follows: item generation, vertification of content validity, pilot study, and test of validity and reliability. In order to verify preliminary instrument, data was collected from 280 hospital employees. Data were analyzed by Varimax factor analysis and Cronbach's ${\alpha}$. There were 21 items in final instrument categorized into 4 factors as 'concern about patient safety management (7 items)', 'confidence about patient safety management (5 items)', 'will for patient safety management (5 items)', and 'recognition about patient safety management (4 items)'. The total varience explanined was 60.4%. The internal consistency, Cronbach's ${\alpha}$. was .86, and reliability of the sucscales ranged from .69 to .87. The results of this study may useful to assess the perception of importance on patient safety management.

Software visualization can assist developers to understand a software system and change its code. The recent development of bottom-up visualization tools demonstrates the advantages by revealing the code that is directly related to a software evolution task. However, the information provided by these tools is limited to the code already investigated by the developers in that task session. To broaden the scope and provide the code information that developers should explore, we propose to present the latest revision of a software system via a class diagram. When a developer clicks on a button, the proposed tool reveals the code changes committed to a configuration management system, and facilitates the understanding of code changes. We also conduct case studies illustrating the advantages of the proposed tool.

건축디자인 초기단계에서 다이어그램은 아이디어 및 디자인 해결방안을 도출하기 위한 분석 도구로써 중요한 의미를 지닌다(Wang, 1999; Do, 1997). 이러한 다이어그램은 시각적 디자인 피드백을 가능하게 함으로써 건축디자인 실무 및 교육에서 필수적인 디자인 도구라고 할 수 있다 (Schon and Wiggins, 1992; Gross, 1996; Kurmann, 1998). 최근에 IT 기술이 건축분야에 적용됨에 따라, 건축가들의 전통적으로 고려되어 왔던 인간의 행동, 자연현상, 건축재료, 건축부재, 대지조건 외에 다양한 IT 기술과 관련된 정보를 분석하고 고려할 필요성을 가지게 되었다. 그러나 이러한 다양한 IT 기술은 건축적인 요소들과 접목되어 적용되기 때문에 건축가들은 디자인 초기단계부터 IT 기술의 접목이 가능한 디자인 도구를 필요로 하게 되었다. 즉, 이는 IT 정보와 공간정보와의 관계 및 적용을 건축가가 빠르게 이해하고 분석하고 이를 디자인에 반영할 수 있도록 도와주는 시각적 다이어그램 표출이 가능한 디자인 도구가 필요하게 되었다. 본 논문에서는 다양한 IT 기술과 공간 정보의 다양한 형태의 관계를 나타내는 3 차원 버블 다이어그램을 이용한 계략 디자인 방법을 제안하고, 이를 기반으로 3 차원 버블 다이어그램을 지원하면서 건축 디자인 초기단계에 이용 가능한 디자인 도구를 개발한다. 본 연구에서 개발된 디자인 도구는 정보의 유형에 따라 다양하게 형태를 변화시킬 수 있는 노드(node)와 연결선(edge)로 구성되고, 저장된 특정 건축정보는 다이어그램으로 생성된 디자인 대안을 평가하는데 사용된다. 일종의 DSS(Decision Support System)인 본 시스템은 디자인 초기단계에서 3 차원 디자인 아이디어를 제공할 뿐만 아니라 다양한 디자인 대안을 빠르게 생성하고 이를 실시간으로 평가함으로써 디자인 효율성을 증가시킬 것이다. 본 시스템은 유비쿼터스 기술이 적용된 신도시에 생성될 통관관제센터 디자인에 실험적으로 적용되었다.

The purpose of this study is to develop a test and verifying the validity and reliability for measuring a effectiveness of e-earning course in cyber university. Twenty-five items were developed based on literature review and were examined by experts in the field. For item analysis, EFA(Exploratory Factor Analysis) was performed with 768 students in first study. In order to validate the test, CFA(Confirmatory Factor Analysis) was conducted with 791 students in second study. The result of the study yielded five factors with 25 items: 1) contents and design, 2) instructor, 3) system, 4) evaluation, and 5) overall course satisfaction. And this research reports the reliability and validity of new test.

Ideals of beauty has expressed variously through the centuries and in different cultures. Each traditional 'togu' has it's own morphology (in the meaning of nonverval linguistic) as using various type of language in each cultural erea. Korean aesthetics on 'dogu'philosophy introduces a whole new set of basic concepts outside western aesthetic framework of beauty Most distinctive is the insistence on overcoming dichotomies, especially between cognition and emotion, (momism)body and mind, self and other, and individual and group. Several topics are particularly illuminating within aesthetics: furniture, calligraphy, traditional garments pose interesting challenging to the art/nature, inside/outside, ethics/desire dichotomies so crucial to moral and cultural context. aesthetics are equally deserving of philosophical scrutiny: the ways in which philosophy of 'dogu'and aesthetics are integrated with daily life, the emphasis on process or understanding context rather than product itself or product 'form'. Dogu did not separate daily life and aesthetics from understanding social context. Language of 'togu' also has own vocabulary and grammar. But we often cannot gain our persnol experience truthful beauty of togu until understand context of understanding. it would be immpossible to explain ,or to analize different way of thinkings and behaivor precisly without understanding same codes of language.

This study aimed to evaluate the reliability and validity of the Korean version of Student Evidence-Based Practice Questionnaire (S-EBPQ) which developed by Upton, Scurlock-Evans, and Upton. Data were collected from 209 nursing students with previous experience of education in evidence-based practice and clinical placement. Using SPSS 25.0, construct validity, concurrent validity and reliability were evaluated. The Korean version of S-EBPQ consisted of 21 items in four domains. The measurement explained 67.0% and the reliability using Cronbach's alpha was .927. The Korean version of S-EBPQ can be used to evaluate the ability of evidence-based practice among nursing students. The tool could be also used to examine the effectiveness of educational programs for evidence-based practice which would contribute to improving the quality of nursing education in Korea.
