Background: Based on that the key function of health technology is improving the quality of healthcare services, our study purports to explore the process of medical device development in detail and to discuss its policy implications. Methods: A total of 12 in-depth interviews were conducted with four groups of industry, hospital, academia, and civil society. All of the interviewees except those from civil society were involved in the new medical device development between 2009 and 2018. We performed a text network analysis and content analysis of the interview data. Results: The frequency and the degree centrality rankings suggested a close association between the utilization issue and the technology development. Similarly, the results of the content analysis showed that the appropriate intervention in the utilization of technology has a direct impact on the progress of development. Under the continuous industrial effort to boost profits by developing new technology, service providers and citizens should be knowledgeable of and make good use of the new technology for the provision of better services. Conclusion: As the development itself would not guarantee the improvement of service quality and better health outcomes, health technology policies should take a more comprehensive view to serve the unmet needs and even to facilitate the technology development.

The need for appropriate technology in global health has expanded dramatically as the gap between industrialized and developing countries continues to expand. However, there is no collective knowledge of appropriate technology in global health. Thus, this study intends to provide light on the latest developments in the field of appropriate technology in global health and to speculate on future directions. A rapid review, or simplified technique, was used to systematically identify and summarize emerging papers. The search technique used the keywords "global health" and "appropriate technology." The total number of papers collected from PubMed and Scopus was 427, and 19 articles were thoroughly reviewed for the result section following the research. The study's conclusions included the following: 1) an assessment of appropriate technology adopted in developing countries; and 2) strategies for implementing appropriate technologies in global health. Additionally, we drew lessons and identified problems to serve as a useful guide for future research and development in appropriate technology. This review uncovered a small but valuable level of information about acceptable technology in global health.

This study evaluated the apron quality management and shield efficiency in the education laboratory for radiology students. For making a proposal of effective control of lead apron, Eighteen aprons, used in 4 university laboratories of dae-gu, Kyungpook area, were analyzed regarding their uniformities, transmission doses, lead equivalent and shield efficiencies. In conclusion, the lead apron uniformity was generally good. Also, the shield efficiency corresponding to lead equivalent was high. However, the quality control of lead apron was not satisfactory. Since there is a potentially possible chance for students to be exposed to a radiation during practical radiation-training in the education laboratory, the quality-control maintenance of the lead apron should be unceasingly maintained for the radiation protection.

Patients' health data is very sensitive and the access to individual's health data should be strictly restricted. However, many data consumers may need to use the aggregated health data. For example, the insurance companies needs to use this data to setup the premium level for health insurances. Therefore, privacy-preserving data aggregation solutions for health data have both theoretical importance and application potentials. In this paper, we propose a privacy-preserving health data aggregation scheme using differential privacy. In our scheme, patients' health data are aggregated by the local healthcare center before it is used by data comsumers, and this prevents individual's data from being leaked. Moreover, compared with the existing schemes in the literature, our work enjoys two additional benefits: 1) it not only resists many well known attacks in the open wireless networks, but also achieves the resilience against the human-factor-aware differential aggregation attack; 2) no trusted third party is employed in our proposed scheme, hence it achieves the robustness property and it does not suffer the single point failure problem.

This study aimed to modify behavior regarding liver fluke and cholangiocarcinoma prevention in Chumphuang district, Nakhon Ratchasima province, Thailand through integrated learning. A total of 180 participants were included through purposive selection of high-risk scores on verbal screening. Participants attended the health education program which applied the health belief model included family based, knowledge station based, academic merit based and community based learning. Data were collected using a questionnaire composed of 4 parts: 1) personal information, 2) knowledge, 3) perceived susceptibility, severity, benefits, and barriers, 4) practice regarding liver fluke and cholangiocarcinoma prevention. The result revealed that the majority were female (79.9%), age ${\geq}60$ years old (33.2%), primary school educational level (76.1%), and agricultural occupation (70.1%). The mean scores of knowledge, perception, and practice to liver fluke and cholangiocarcinoma prevention, before participated the integrative learning were low, moderate, and low, respectively. Meanwhile, the mean score of knowledge, perceived susceptibility, severity, benefits, and barriers, and practice regarding liver fluke and cholangiocarcinoma prevention, were higher with statistical significance after participation in the integrated learning. This finding indicates that health education programs may successfully modify health behavior in the rural communities. Therefore they may useful for further work behavior modification in other epidemic areas.

Over the last decade, genome-wide association studies (GWASs) have provided an unprecedented amount of genetic variations that are associated with various phenotypes. However, previous GWAS were mostly conducted in European populations, and these biased results for non-Europeans may result in a significant reduction in risk prediction for non-Europeans. An issue with the early GWAS was the winner's curse problem, which led to misleading results when constructing the polygenic risk scores (PRS). Therefore, more non-European population-based studies are needed to validate reported variants and improve genetic risk assessment across diverse populations. In this study, we validated 422 variants independently associated with glycemic indexes, liver enzymes, and type 2 diabetes in 125,872 samples from a Korean population, and further validated the results by assessing publicly available summary statistics from European GWAS (n = 898,130). Among the 422 independently associated variants, 284, 320, and 361 variants were replicated in Koreans, Europeans, and either one of the two populations. In addition, the effect sizes for Koreans and Europeans were moderately correlated (r = 0.33-0.68). However, 61 variants were not replicated in both Koreans and Europeans. Our findings provide valuable information on effect sizes and statistical significance, which is essential to improve the assessment of disease risk using PRS analysis.

Osteoporotic fractures (OFs) are critical hard outcomes of osteoporosis and are characterized by decreased bone strength induced by low bone density and microarchitectural deterioration in bone tissue. Most OFs cause acute pain, hospitalization, immobilization, and slow recovery in patients and are associated with increased mortality. A variety of genetic studies have suggested associations of genetic variants with the risk of OF. Genome-wide association studies have reported various single-nucleotide polymorphisms and copy number variations (CNVs) in European and Asian populations. To identify CNV regions associated with OF risk, we conducted a genome-wide CNV study in a Korean population. We performed logistic regression analyses in 1,537 Korean subjects (299 OF cases and 1,238 healthy controls) and identified a total of 8 CNV regions significantly associated with OF (p < 0.05). Then, one CNV region located on chromosome 20q13.12 was selected for experimental validation. The selected CNV region was experimentally validated by quantitative polymerase chain reaction. The CNV region of chromosome 20q13.12 is positioned upstream of a family of long non-coding RNAs, LINC01260. Our findings could provide new information on the genetic factors associated with the risk of OF.
