This study investigates the factors affecting Industry 4.0 adoption in the curriculum of university students in Ho Chi Minh City, Vietnam. Universities need to respond to the changing faces of Industry 4.0 and, hence, Education 4.0. A mixed method including both qualitative and quantitative methodologies was utilized. An in-depth interview was carried out for exploring, reviewing, and testing content validity of constructs and measurement items. The pilot study was conducted with 120 respondents. The conceptual model and hypotheses were developed using data collected by a questionnaire survey distributed to 584 respondents by both electronic and paper forms with non-probability and convenience sampling techniques. The result of structural equation modeling showed that occupation relevance, skills, facility conditions, and social influence impacted on the intermediates variables, namely, relevance advantage, perceived usefulness, behavioral intention-to-use, and actual use. The independent variables are occupation relevance, skills, facility conditions, and social influence. They impact actual use through mediating constructs such as relevance advantage, perceived usefulness, and behavioral intention-to-use. The findings suggest that universities and students' efforts aimed at increasing the factors' perceptions of adoption of Industry 4.0 will contribute to implementation success, where success is defined as effectual usage of Industry 4.0.

The purpose of this study was to explore the relationships between the concept of heat and that of temperature for elementary students. Eight multiple choice type questions with explanation of reasons for selection were developed based on previous researches and the analysis of science curriculum for elementary students. The students of 9, 10, 11 years(n=292) were selected from two elementary schools in Taegu City. The responses of students' multiple choice and their explanations were analysed in each items χ² test used for the relationships between types of heat and temperature conceptions Half of elementary student could discriminate the two terms of heat and temperature, majority of them thought that heat is likely to be hot and temperature is the quantity of heat, which is not based on scientific conception. Elementary students thinkings about heat could be classified with material type of heat and molecular kinematics type. Material type of heat were more popular than with molecular kinematics type, although the latter is increased. Majority of students answered correctly in qualitative questions of mixing of hot and cold water, but about only one third of them answers in quantitative questions. Subtraction of cold temperature from hot temperature was the most popular explanation, even though one-quarter of students summed up the two temperature in quantitative situation of mixing hot and cold waters. Those who thought heat as the molecular kinetic responded more correctly in most difficult questions than those who as the material. Therefore, we concluded that the types of heat conceptions affected the concept formation of temperature.

Currently, the investment on Research and Development(R&D) for defense core technology is continuously increasing to maintain advanced country's R&D level. In accordance with this trend, the national defense R&D investment management system is being more strengthening, and importance of performance evaluation is being emphasized more and more. However, the existing indicators of performance evaluation for defense core technology R&D is limited in efficient management because of the qualitative evaluation items and subjective allocation of points. In this paper, we developed a novel indicator for defense core technology R&D performance evaluation through domestic and foreign related literature and inquiry, brainstorming, and analysis techniques by Stepwise Multiple linear Regression(SMR) and Analytic Hierarchy Process(AHP). And we verified effectiveness of proposed indicators of performance evaluation by comparing with the existing evaluation indicators. Our proposed indicators for performance evaluation will create superiority performance on defense R&D fields.

Background: Stroke patients exhibit arm global synkinesis (GS), involuntary movement due to muscle weakness and irregular muscle tension. But currently there are few studies examined the effects of GS on activates of daily living in stroke patients. Objectives: To investigate the effects the effects of task-oriented bilateral movements, which promote brain plasticity and are based on neurological theory, using the unaffected arm and the affected arm. Design: Quasi-randomized trial. Methods: Twenty stroke patients were randomly assigned to experimental group I (n=10) and experimental group II (n=10). Before the intervention, arm GS was measured using surface electromyography, and the Motor Activity Log evaluated the quantitative and qualitative uses of the affected arm in daily life. The same items were measured four weeks later. Results: The changes in the GS of the arm of experimental group I showed statistically significant differences only in bending motions (P<.05). Both groups showed statistically significant differences in the amount of use (AOU) and the quality of movement (QOM) scores (P<.01). Comparing the groups, statistically significant differences in GS appeared during bending motions (P<.05), and in the AOU (P<.01) and the QOM scores (P<.05). Conclusion: The intervention in GS reduced the abnormal muscle tension of the affected side by increasing the use of the ipsilateral motor pathway, indicating its effectiveness in improving upper limb functions with smooth contraction and relaxation of the muscles.

Objectives : The results from randomized controlled trials on traditional medicine have been negative or ambiguous. The appropriateness of the research methodology started to be questioned. However, the research methodology appropriate for studying traditional medicine has not been well-established. This study aims to explore the appropriate research methodologies for clinical studies on acupuncture. Methods : Clinical researches evaluating the efficacy and effectiveness of acupuncture for back pain were systematically searched and evaluated focusing on research methodology. The acupuncture treatment protocol is evaluated by 9 items which is individual treatment based on diagnosis, combining proximal and distal acupoints, exact location of acupoint, De Qi, adequate stimulation, duration of acupuncture, treatment sessions, treatment interval, and establishing relationship between patients and doctors. Results : Systematic review of acupuncture researches on low back pain suggested that observational studies and pragmatic trials rather than explanatory studies could incorporate these elements. Qualitative studies also could help understanding complex characteristics of acupuncture treatment which could not be evaluated by quantitative studies. Conclusions : In designing clinical researches on acupuncture, various study designs, especially observational study and pragmatic study, should be considered according to research objectives and subjects. The efforts to incorporate the core characteristics of acupuncture practiced in everyday clinical setting are also essential.

Since ultrasound has different reflections depending on components of organization, analysis of ultrasound images of skeletal muscle can offer both quantitative and qualitative reports as concerns skeletal muscle structure. This study is focused on the ultrasound method for evaluating the structural characteristics of skeletal muscle and also conducted to examine its practicality. After obtaining images of the elbow flexors from an ultrasound image device with 88 normal subjects whose ages were between twenty and seventy years old (44 men and 44 women), muscular density and white area index (WAI) which indicated structural characteristics of skeletal muscle were analyzed with gray scale analysis. The study examined correlations between subject's age and items which obtained from measuring ultrasound images and the differences in relations to sex and age. Muscular density and WAI had a high correlation with age and were significantly increased in men and women with greater age. The quantitative evaluation method of skeletal muscle structure which analyzed the ultrasound images has high practicality because it is a non-invasive method which complements physical therapy diagnosis and research methods and promotes functionality evaluation.

Objectives: This purpose of this study was to examine the trends in interventional research and analyze the contents and results of intervention through a systematic literature review of the domestic research literature, suggesting the effect of an oral care program on elementary school students. Methods: A total of 262 articles were retrieved initially, and the duplicate articles were then removed, excluded after screening titles, abstracts, and full-text articles. Finally, a total of 16 papers were used in the review. Results: The study included 9 articles with the nonequivalent control group pretest-posttest design and 7 with the one-group pretest-posttest design. All articles were of non-randomized studies. The most common index of the interventional effect was dental plaque. Further, oral health behaviors and knowledge, perception, self-efficacy, and DMFT index were common indices. In the quality assessment, in the "blinding of outcome assessment" among six items of ROBANS, 12 studies showed a high risk of bias. Conclusions: In order to develop an interventional oral health care program for elementary school students and evaluate the effectiveness, a strict research design and qualitative improvement of research reports are required, and continuous research should be conducted to develop a systematic protocol.
