Innovative and advanced technologies, including robots, augmented reality, virtual reality, the Internet of Things, and wearable medical equipment, have largely emerged as a result of the rapid evolution of modern society. For these applications, pressure monitoring is essential and pressure sensors have attracted considerable interest. To improve the sensor performance, several new designs of pressure sensors have been researched based on resistive, capacitive, piezoelectric, optical, and triboelectric types. In particular, optical pressure sensors have been actively studied owing to their advantages, such as robustness to noise and remote sensing capability. Herein, a review of recent research on optical pressure sensors with self-powered sensing, remote sensing, high spatial resolution, and multimodal sensing capabilities is presented from the viewpoints of design, fabrication, and signal processing.

Several self-administered dietary assessment questionnaires have recently been developed, validated, and used in nutritional epidemiological and clinical studies in Japan. This article describes recent evidence on development and validation of them. After extensive search of published articles both in English and Japanese languages, we identified 25 articles on 13 questionnaires of which validation studies have existed. Number of foods/menus assessed varied from 31 to 169 according to questionnaires. Eleven questionnaires were food frequency type, either with fixed portion size or semiquantitative, and two diet history types. All the 13 questionnaires were validated against intakes assessed with dietary record or 24-hour recall, and only two with biomarkers. Number of subjects used in the studies was between 23 and 350. All the studies used adult subjects. In the studies with dietary record or recall, the correlation coefficient for or orgy intake was between 0.22 and 0.65 (median = 0.44). Median correlation coefficient for nutrients was between 0.21 and 0.61. In the studies with biomarkers, serum marine-origin n-3 polyunsaturated fatty acids and carotenes, and urinary potassium seemed useful biomarkers. In conclusion, recent progress of this field in Japan is remarkable. But more research is needed for validation studies with biomarkers, and the development and validation of questionnaires for children and elderly subjects. (J Community Nutrition 5(2) : 83∼92,2003)

Purposes : The Purpose of this study was to review a current status on acupuncture and traditional Chinese medicine in Canada focusing on the rules of regulatory bodies of 5 states including legislation history, development in professional self-regulation, education and evaluation system. Methods : Based on literature review, we studied on 5 legislated states cases, educational accreditation status and licensure system. We also interviewed on a person who is a chair of CTCMA & CARB-TCMPA and more TCM practitioners in British Columbia within educational topics. Results & Conclusions : Acupuncture legislations have been approved by the governments in Canada between 1988 and 2014 within the acceptance of self-regulation. Since then, regulatory bodies in each states have tried to strengthen their duties and rights as a healthcare professionals. Based on firm laws and regulations, occupational competency-based education in acupuncture and TCM has been gradually improved and established quite well in parallel with a development of higher educational system in Canada.

Purpose: This study was to develop a Health Dieting Competency (HDC) scale to assess self-rated health dieting competence of college students. Methods: The scale was developed as follows: items generated, and tests of validity and reliability. Items were developed through a literature review, review of instruments, and interviews. A panel of four experts reviewed the scale for content validity. Factor analysis, Pearson correlation, descriptive statistics and Cronbach's ${\alpha}$ were used to analyze the data (N=183). Results: In the preliminary stage, thirty-three items were generated. Final items were fourteen that were selected through exploratory factor analysis. The HDC scale was consisted with five factors and fourteen items that were Goal-Directed (5-items), Health Support (2-items), Health Self-Efficacy (3-items), Health Perception (2-items), and Escaping from Health (2-items). The internal consistency of HDC as measured by Cronbach's ${\alpha}$ was .78. Conclusion: Content validity, construct validity, and reliability of the HDC were established. The HDC scale is a reliable and valid instrument for early adulthood youth who are willing to assess health dieting competency.

This study details a researcher's self-study journey in advancing from a computational thinking (CT) novice to an expert. The researcher went through a four-stage process, with a preliminary literature review preceding the four stages. From the literature review, the computational thinking analysis (CT_AT) tool was developed for use in stage one to analyze science, technology, engineering, art, and mathematic (STEAM) modules. Although no discernable patterns were found in analyzing the five science and five engineering-based modules, the analysis revealed which CT practices were missing or weakly exposed. In stage two activities were suggested to promote these missing or weakly exposed practices. Stage three required the researcher to develop his own STEAM module from the viewpoint of exposing students to CT. The fourth stage was to validate the CT_AT through interviews with pre-service and in-service teachers. These interviews led to changes in the CT_AT tool and, as a result, the researcher produced a guidebook that could be used by teachers in their own CT studies. This guidebook can be used by teachers to develop and become competent in CT skills.

Based on a survey conducted on 125 students in the Department of Computer Engineering at K University, the following results were obtained by analyzing ways to improve academic ability. Male students should pay more attention to grade points management than female students before completing their military service. Students with high self-assessed academic ability score higher than students with low self-assessed academic ability. As long as students don't spend too much time, a student's part-time job is not an obstacle to their study. Compared to Seoul, Gyeonggi, and Incheon regions, students from Gangwon and other regions should pay special attention to some pre-classes to understand regular university lectures. In undergraduate education, a student's major aptitude is not a big problem. In order to change major, students need counseling about their major's aptitude only at the beginning semester. In order to get good grades, the achievement of the will to study is more important than the will to study itself. Professors should encourage students to review what they have learned in class after class and always assure students sincerity in their studies through the counseling process.

Background: Most job exposure matrices (JEMs) have been developed for chemical and physical hazards in the United States (US). In addition, the overall validity of most JEMs of work organization hazards using self-reported data in the literature remains to be further tested due to several methodological weaknesses. Methods: This paper aims to review important methodological issues with regard to a JEM of work organization hazards using self-report data and to present a research protocol for developing a four-axis (job titles, hazards, sex, and time) JEM of major work organization hazards using the US General Social Survey-Quality of Work-Life (GSS-QWL) data (2002-2018; N = 7,100 workers). Results: Five methodological weaknesses in existing JEMs of work organization hazards using self-report data were identified: having only two axes (hazard and occupation), using psychometrically weak items and scales, including scales having little interoccupational variability, unresolved optimal minimum numbers of subjects per occupation, and low accessibility. The methodological weaknesses were successfully addressed in the proposed research protocol. Conclusion: The work organization JEM to be developed will significantly facilitate and strengthen occupational epidemiological studies on work organization hazards and major health outcomes, improve national and occupational surveillance of work organization hazards, and promote interventions for a healthy work environment in the US.

Autoimmune disease is known to be caused by unregulated self-antigen-specific T cells, causing tissue damage. Although antigen specificity is an important mechanism of the adaptive immune system, antigen non-related T cells have been found in the inflamed tissues in various conditions. Bystander T cell activation refers to the activation of T cells without antigen recognition. During an immune response to a pathogen, bystander activation of self-reactive T cells via inflammatory mediators such as cytokines can trigger autoimmune diseases. Other antigen-specific T cells can also be bystander-activated to induce innate immune response resulting in autoimmune disease pathogenesis along with self-antigen-specific T cells. In this review, we summarize previous studies investigating bystander activation of various T cell types (NKT, γδ T cells, MAIT cells, conventional CD4⁺, and CD8⁺ T cells) and discuss the role of innate-like T cell response in autoimmune diseases. In addition, we also review previous findings of bystander T cell function in infection and cancer. A better understanding of bystander-activated T cells versus antigen-stimulated T cells provides a novel insight to control autoimmune disease pathogenesis.
