  • Previous research has shown that wind acceleration components produce a signal that can vibrate single-degree of-freedom oscillators, whose dynamic responses enable to configure design spectra for structures subject to wind. These wind design spectra present an alternative method for evaluating the dynamic response of structures and are a suitable tool for running modal analyses. Here, a generalised method for producing wind design spectra is proposed. The method consists of scaling existing spectra to adjust to a wider range of building properties and terrain conditions. The modelling technique is tested on a benchmark building to prove that its results are consistent with experimental evidence reported in the past.

  • The purpose of this study was to analyze one science teacher's understanding of student argumentation and his explicit teaching strategies for implementing it in the classroom. One middle school science teacher, Mr. Field, and his students of 54 participated in this study. Data were collected through three semi-structured interviews, 60 hours of classroom observations, and two times of students' lab reports for eight weeks. Coding categories were developed describing the teacher's understanding of scientific argumentation and a description of the main teaching strategy, the Claim-Evidence Approach, was introduced. Toulmin's approach was employed to analyze student discourse as responses to see how much of this discourse was argumentative. The results indicated that Mr. Field defined scientific inquiry as the abilities of procedural skills through experimentation and of reasoning skills through argumentation. The Claim-Evidence Approach provided students with opportunities to develop their own claims based on their readings, design the investigation for evidence, and differentiate pieces of evidence from data to support their claims and refute others. During this approach, the teacher's role of scaffolding was critical to shift students' less extensive argumentation to more extensive argumentation through his prompts and questions. The different level of teacher's involvement, his explicit teaching strategy, and the students' scientific knowledge influenced the students' ability to develop and improve argumentation.

  • Purpose: This study was conducted to evaluate the effectiveness of an evidence-based nursing (EBN) course using action learning-based team learning in undergraduate nursing students. Methods: A quasi-experimental pretest-posttest control group design was employed. The participants who consented were 45 second-year nursing students (22 in the experimental, 23 in the control group) from a university in G-city, Korea. The intervention included lectures, practicals, team activities and reflection on overviewing EBN, formulating clinical questions, searching the evidence, and criticizing the research articles. At the beginning and the end of the 7-week EBN course, the participants completed self-reported questionnaires. Frequencies, $x^2$-test, t-test, and ANCOVA with the SPSS program 18.0, were used to analyze the data. Results: The experimental group showed significantly higher scores on EBN competency (F=25.80, p<001), information literacy (F=13.75, p=.001), and proactivity in problem solving (F=5.32, p=.026) than the control group. Conclusion: This study provides evidence that an EBN course improves undergraduate nursing students' EBN competencies, information literacy, and proactivity in problem solving. Team learning in EBN education can be an effective teaching strategy.

  • Purpose: How to build the positive emotion of customer is very important, because it affects the positive attitude. Brand evidence has a significant impact on consumer behavior in terms of reinforcing consumers' perception of food service companies and differentiating them from competing brands. Thus, this study examines the effect of brand evidence on emotion (positive emotion and negative emotion), and attitude in restaurant industry. Research design, data, and methodology: This study examines the structural relationship among brand evidence, emotion, and attitude. Brand evidence divide into three sub-dimensions such as physical evidence, core service, and employee service. In order to test the purposes of this study, research model and hypotheses were developed. The questionnaire items were modified and used according to the content of this study based on previous studies. All constructs were measured by multiple items tested and developed in the previous research. The data were collected from 439 restaurant users from Seoul area were analyzed using SPSS 22.0 and SmartPLS 3.0 program. A total of 460 questionnaires were distributed and a survey was conducted for 4 weeks, and a total of 439 were used for analysis, excluding non-response data and 21 unusable response data among the collected questionnaires. Frequency analysis was conducted to identify the general characteristics of the survey subjects. To measure the reliability and validity of the measurement tools, confirmatory factor analysis was conducted. Structural model analysis was conducted to verify the research model. Result: The findings demonstrate that physical evidence, core service, employee service had positive effects on positive emotion. And core service and employee service had negative effects on negative emotion while physical evidence did not have. Also, positive emotion had positive effect on attitude and negative emotion had negative effect on attitude. Conclusions: The findings of this study provide guidelines on how to enhance competitiveness in restaurant industry through understanding brand evidence's effects on raising perceived consumer's emotion and attitude. Therefore, food service companies should establish a marketing strategy that can stimulate positive emotions through brand evidence, which is all factors related to service brands that influence consumers' evaluation of service products and purchase decision-making process.

  • Purpose: The main objective of this paper is, first, to assess a body of research evidence that articulates the impact of environmental and design factors on safety, quality of life, and health of the elderly who reside in geriatric hospitals or other elderly care facilities and, second, to draw out design implications that can be incorporated into design process and design decisions to help create healing environments for the elderly. Methods: Extensive literature review has been conducted to identify rigorous empirical studies that link the design of elderly care facilities to health-related outcomes and scrutinized peer-reviewed articles published in many different fields including architecture, psychology, nursing to gerontology. Results: The review found a growing body of rigorous studies that identified physical environmental and design factors that improve safety, quality of life, and health of the elderly in geriatric hospitals or other elderly care facilities. Implications: The findings of the review can be translated to design decisions to promote safety, quality of life, and health of the elderly in geriatric hospitals or other elderly care facilities.

  • 사회가 민주화, 선진화되어감에 따라 합리적인 정책과정의 중요성이 강조되어 이른바, 증거기반 정책(evidence-based policy) 이 정책 분야에서의 중요한 화두로 떠오르게 되었다. 증거기반 정책, 그 중에서도 통계에 기반을 둔 정책에 관한 관심이 고조되고 있기는 하지만 구체적인 정책분야에서 통계가 어떻게 사용되고 있는지에 대한 구체적인 사례들이 소개된 것은 그다지 많지 않다. 본 연구의 목적은, 현재 국민은행이 작성하여 공표하는 주택가격지수가 구축, 발전되어 온 과정을 더듬으면서 구체적으로 통계가 어떻게 주택정책의 기반으로 활용되어 왔는지를 조명하는데 있다. 시기별 주택가격지수의 통계적 특징 및 문제점들을 지적하고, 이러한 문제점들이 개선되는 과정을 살펴본다. 아울러 주택가격지수가 구체적인 부동산 관련 정책과정에서 어떻게 활용 되는지를 소개한다.

  • Purpose: The purpose of this study is to provide understandings about EBD research trends in Korean healthcare architecture research. Method: The systematic literature review was conducted, while comparing the characteristics of research papers in Journal of Korea Institute of Healthcare Architecture with EBD related research papers among them. Results: It is found that the difference of research method utilized between healthcare research in general and EBD research. Specifically, a research method most utilized in general is a field study. In EBD research, however, literature review is most frequently used. Implications: This study can be used as a reference point for further development of EBD research in Korean healthcare architecture. In addition, research results can be used as a communication tool with healthcare specialists such as doctors and consultants in a healthcare project team. Thus, this study is anticipated to play a preliminary role for the development of healthcare architecture design in Korea.
