Practice is essential in art and design. Through practice, artists gain tacit knowledge that is hard to acquire from conventional academic studies. This paper characterizes practice-led research in the study of fashion and textile design through the investigation of practice-led research theses in the UK. According to relevant literature, which includes four exemplary case studies, the following features can be drawn: First, the methodology is different in each case and the use of practice is unconventional. Second, the research is not always aimed at making products. Third, the structure follows an iterative process. Fourth, the ratios of theory and practice are different and various theories are used. Fifth, a personal journal or diary is used for reflection as a major aid to research. Lastly, the process should be recorded by a thorough academic method. Practice-led research can have unexpected outcomes in theory and practice. It can be a good option for fashion practice research to develop a better evaluation method and reduce the gap between subjectivity and objectivity.

The LED light source has many excellent advantages for the application of LCD backlight module. As we know, the operational temperature can significantly influence the characteristics of LEDs. Heat can damage the LED 's quality, and decrease its lifetime and output light intensity. In this paper, we perform computer software, Flomerics CFD (Computational Fluid Dynamics), to simulate heat distribution of the 20.1" LED backlight module we designing, and realize how the different heat sinks can solve the serious heat problem in practice.

LED luminaires as a lighting system have attracted much research attention due to their high efficiency and long lifetimes. However, disappointing outcomes have been noted in terms of performance levels and lifetimes as compared to desired system requirements in practice due to certain electrical and thermal characteristics of LEDs. LM-80 and TM-21 established by IESNA are the best known standards for lifetime test procedures and estimation techniques. However, they only handle LED light sources without guaranteeing the LED luminaire in a reliability test. They also operate for more than 6,000 hours and undergo various stresses, such as the operating current and temperature. Therefore, a lifetime standard for LED luminaires has not yet been established. This paper proposes a conceptual design of a lifetime test system for LED headlamps depending on the operating environment. Eventually, this method can assist with evaluations of the validity of lifetime standard tests of LED headlamps.

Today's elementary schools emphasize practice- and learner-based computer courses. In this research, we found solutions to the above issues by adapting a demonstration/practice teaching method led by multiple teaching assistants, expanding lessons tailored to each student's own level. We chose fourth graders from three classes at Elementary School as the subject for this research. Through this research, we have analyzed the students' study results, self-efficacy, response and interest in the computer courses by examining three groups of students: the first group led by a teacher's demonstration and practice, the second group by a teaching assistant's demonstration and practice, and the last by multiple teaching assistants' demonstration and practice. As a result, we were able to show that a computer course taught by multiple teaching assistants will help not only induce an interest and motive for a mutual learning environment among the students, but also bring positive effects on the study results and self-efficacy.

This paper will investigate how animated practice can be a research form as practice-led research in an ethnography approach. This practice-led research will explore the issue of the construction of contemporary identities (based on the strange case of Dr. Jekyll and Mr. Hyde) and in particular, the Korean youth culture and identity, exemplified, for example, creation of 'avatars' in the virtual characters of animated online games such as Massively Multiplayer Online Role-playing Games (MMORPGs). In this proposed discussion, I will argue that the sudden period of change in contemporary Korea bears some resemblance to the Victorian era as explored in gothic fiction (e.g. Jekyll and Hyde). In this sense, my animation investigates the connection between the fictional Jekyll and Hyde and a real murder incident by a young Korean boy, which actually happened on the 16th November 2010, in SouthKorea.I will, therefore, construct this practice-led research to obtain the primary data consisted of online and offline practices in 'social ethnography'. These practices engage with specific Korean youth identity, comparing the 'avatar' with the real lives of participants. However, this paper will only focus on the (ethnographic) research process and strategy, using animated (visual) practices, rather than giving the meaning of the specific case of 'Korean-ness'. Eventually, I will explore the four different animated representations as it presents the distinctive animated realties or documentaries by online and offline practices. My intention is to visually interpret the issue of 'Korean-ness' within its socio-cultural context, adapting the convention and code of Jekyll and Hyde concept into an animated documentary in the 'virtual' world (auto-animated documentary by recording avatar interviews and online game footages) and the 'real' world (self-created animated documentary, based on real people and events).

Purpose: Competency is a key foundation of the nursing education curriculum and a baseline element of nursing practice. The purpose of this study was to explore the competencies of community health nurses in a maternal early childhood sustained home-visiting program based on nurses' field experiences. Methods: The participants were 21 nurses who had more than 1 year of experience in this program. Reflective interviews were performed; lasting 1 hour per nurse, on August 18, 2016, and the collected data were analyzed using qualitative directed content analysis. Results: Twenty-four themes were extracted for 9 competencies. The major themes included implementing a long-term relationship-based approach, providing client-led service rather than expert-led service, helping mothers with psychosocial difficulties, and applying skills in a practical manner in the home environment. Conclusion: In order to develop a home-visiting program as part of maternal-early childhood nursing practice, nurses should develop competencies that help them make significant and positive interventions. Results indicate that the curriculum for community health nurses should be changed to improve competencies in building relationships with clients and to focus on the application of skills in specific cases and in clinical practice.

Developing countries may pay attention to bibliometric indicators in accordance with their scientific development plans. Bibliometrics research topics and bibliometric indicators have grown dramatically in Iran since 2000 as a part of the post-war reconstruction programs. This paper aims to highlight how scientometrics may attract attention in developing countries such as Iran in response to national movements in education and science. An in-depth review on available guidelines for promotion of innovation, science, and technology in Iran was done followed by a review on previous research in this topic. Further data were gathered from Scopus and other sources. The findings show a considerable growth in research output of Iran in recent years and expansion of bibliometrics studies and jobs accordingly. Combined with research output measures, more attention was found in academia about cross-section development of science and technology in Iran. The demand in society has led to the foundation of scientometrics programs in Iranian universities as well as scientometrics departments in central libraries and research deputies in major academic institutions. The changing image of science and research in Iran has a relation with the growth of scientometrics academic and professional departments. The lessons taught from this mutual collaboration can be used in other developing nations.

Purpose: Emergency medical service (EMS) personnel are at high risk of spreading infection. In this study, we used the PRECEDE model to identify the knowledge, status, and barriers to infection control among Korean paramedics to provide basic infection control data. Methods: A total of 164 respondents were analyzed for the study. A questionnaire was administered and collected through an online self-response platform. Descriptive analysis, t-test, ANOVA, multiple regression, and logistic regression analyses were performed to determine infection control practices and associated factors using SAS 9.4. To identify the pathways and direct, indirect, total effects based on the PRECEDE model, we used AMOS 26.0. Results: Highly rated self-efficacy (OR 8.82, 95% CI: 3.23-24.09), awareness (OR 6.05, 95% CI: 2.06-17.72), and enabling factors (OR 3.23, 95% CI: 1.18-8.78) led to superior infection control. As a result of the structural model analysis, the highly rated enabling factors and awareness led to superior practice patterns. Conclusion: Practice is related to self-efficacy, awareness, and enabling factors; however, further research is needed to develop strategies for infection control. In particular, institutional arrangements are needed to improve the enabling factors. Improving infection control performance may lead to better infection control and enhanced protection of EMS personnel and patients against infection risks.

Introduction of BIM(Building Information Modeling) was led by public institutions, and all buildings over a certain size were obligated to apply BIM. However, through various attempt to apply BIM to actual practice, people had doubt whether it is a usable technology in reality appeared. Therefore, this study investigated cases about implementation strategies of foreign countries, and conducted survey on BIM performances and preparation in architectural design firms. On the basis of this, it suggests the long-term development strategy of BIM and the basic direction of road map to adopt BIM effectively to domestic architectural design market. After considering the cases abroad and the results of survey, it is identified that incentive policies supporting finance and education should be carried out together with partially obligation method led by government in order to introduce BIM into architectural design market effectively by reflecting current situation of architectural design firms.

Objectives : The purpose of this study is to examine correlation between clinical practice and self-esteem in empowerment of dental hygiene students. Methods : Subjects were 399 dental hygiene students in Gwangju and Jeollanamdo. They completed self-reported questionnaire from November 5 to 20, 2012, after infromed consent was accepted. Results : Higher scores in empowerment was found in students who were satisfied with curricula (p<0.05) and major(p<0.001), having higher average grades (p<0.001), and who felt the better atmosphere of the clinical practice (p<0.05) and got more marks in empowerment. The empowerment of the students had a significant positive correlation to their satisfaction with clinical practice(p<0.001) and self-esteem(p<0.001). Satisfaction with clinical practice had a significant positive correlation to self-esteem(p<0.01). Conclusions : Satisfaction with major and higher self-esteem led to empowerment, sustained research efforts should be directed into the development and application of programs that could bolster these factors.
