Background: With the development of information and communication technology, there is a growing number of people looking for health information on the internet. This pilot study was performed to analyze the pattern of pharmacist consultation on the internet portal site. Methods: Questions and answers posted on the portal site "Naver Jisik-iN" from March 1st to 31th in 2016 were collected. Medications asked were categorized into prescription drugs, nonprescription drugs, sanitary aids, emergency drugs, functional health foods, and others. Medications were subcategorized into 14 according to the anatomical therapeutic chemical classification system. Questions were divided into 10 categories based on Hepler's drug-related problems. Results: Of the 955 cases, females accounted for 59.5% and inquirers from 11 to 40 years old, 89.4%. The number of prescription drugs, nonprescription drugs, sanitary aids, emergency drugs, functional health foods, and others were 428 (44.8%), 328 (34.3%), 31 (3.3%), 2 (0.2%), 122 (12.8%), and 44 (4.6%), respectively. Questions for drugs acting on alimentary tract and metabolism took up 27.4% followed by those on nervous system, 13.6% and anti-infectives for systemic use, 12.2%. Pharmacist consultation regarding drug information, drug interaction, and adverse reaction occupied 47.9%, 15.2%, and 12.3%, respectively. Conclusion: Health counseling through online is predicted to increase steadily, so pharmacists should broaden their boundaries beyond off-line pharmacies to meet social needs.

Via the Internet, the information infrastructure of modern health care has already established medical information systems to share electronic health records among patients and health care providers. Data hiding plays an important role to protect medical images. Because modern medical devices have improved, high resolutions of medical images are provided to detect early diseases. The high quality medical images are used to recognize complicated anatomical structures such as soft tissues, muscles, and internal organs to support diagnosis of diseases. For instance, 16-bit depth medical images will provide 65,536 discrete levels to show more details of anatomical structures. In general, the feature of low utilization rate of intensity in 16-bit depth will be utilized to handle overflow/underflow problem. Nowadays, most of data hiding algorithms are still experimenting on 8-bit depth medical images. We proposed a novel reversible data hiding scheme testing on 16-bit depth CT and MRI medical image. And the peak point and zero point of a histogram are applied to embed secret message k bits without salt-and-pepper.

To analyze and compare the most influencing factors on cloud computing adoption (CCA) in the healthcare organization, a systematic review and meta-analyses of studies was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Cochrane collaboration recommendations. A search of PubMed, ScienceDirect, Springer, Wiley Online, and Taylor & Francis Online digital libraries (From inception to January 19, 2022) was performed. A total of 17 studies met the defined studies' inclusion and exclusion criteria. Statistical significance difference favoring most influencing factors on CCA were (MD 0.76, 95% CI -1.48 - 3.01, p <0.00001, I² = 90%), (MD 1.40, 95% CI -4.76 - 7.55, p < 0.00007, I² = 97%) (MD 0.17, 95% CI -2.69 - 3.03, p<0.00001, I² = 96%) for technology vs. organizational, technology vs. environmental and business vs. human factors, respectively. Organizational and environmental factors had greater impacts on CCA compared with technological factors. Moreover, business factors were more influential than the human factors.

This study carried out to assess the quality of the information presented on the internet about nutrition specifically in the field of health functional food by monitoring with 10 panels from May, 2004 to October. Four hundred seven relevant websites were initially selected from a process using 5 search engines and the keywords ‘food’ and ‘nutrition’, and 404 sites actually met all inclusion criteria. Most of the sites evaluated 219 (54.20%) were commercial sites and then distributed noncommercial organization site 93 (23.0%), individual site 92(22.8%). Assessment quality indicator was carried out using the 17 necessary requisites, which has been developed to enable users and information providers to judge the quality of food and nutrition information. The mean score for quality grade was 11.07, five site out of a maximum score of 17 and two sites with the lowest total scores for the quality of food and nutrition information. Noncommercial organization site assessed achieved the highest score in accurate and useful informations to the public. Low ranked sites had the most inaccurate or misleading information, emphasizing only the positive aspects of the information, with little or no evidence. Many commercial sites used personal testimony as the most popular ‘proof’ for the effectiveness of product. This was anecdotal rather than scientific evidence based on which the objective validation was difficult to be made. Therefore, it can be challenging for both public and health professionals, to sort out useful information from a plethora of advertisements and promotions on the web sites. Our results suggest that nutrition professionals should talk about useful information of health, food and nutrition with public and help them find the best available information when using the internet.

Recently with the development in computer technology and its communication system, many changes in medical informatics enable us to use various medical information regardless of time or place. There are many home pages on the web, which provide medical counseling and hospital information. On May 11th 1999, Korean Rheumatology Health Professions Society began its new service as a home page on the web with various rheumatologic health information, questioning/ answering, and so on. This study was undertaken to examine the content and the purpose of health counseling on the web. The data was collected from 173 questioners who visited questioning/ answering site in the KRHPS home page for May 11th, 1999 through November 10th, 1999. Most of the questioners consulted the health problems of their or their families. Over two thirds of them were already diagnosed medically. Rheumatoid arthritis was the most frequent one. Other diseases, such as, osteoarthritis, ankylosing spondylitis, Still's disease were also on the list. Most of the questioners wanted to know treatment strategies, to consult about their symptoms, and to make diagnosis. And many questioners wanted detailed explanations about their diseases or the informations regarding the hospital. These findings suggest that the health counseling on the web may be used to supplement the lack of direct medical interviews with doctors. It also is expected to guide the patients to the right direction.

Background: The Internet has advantages in terms of accessibility and amount of information, and the search for health information over the Internet is increasing exponentially. The purpose of this study is to analyze the information generated about some dental treatment on the internet by year. Methods: Naver Knowledge (JisikIn in Korean) which is an interactive search service was selected as the first search site in Korea. Scaling, wisdom tooth extraction, and endodontic treatment that can be paid by Korean health insurance were selected. Finally, 4,729 questions about scaling, 23,963 wisdom teeth extraction questions and 17,733 endodontic treatment questions were extracted. The question contents, the information about the questioner and the answerer, and an error of answers were investigated. Frequency analysis was used and chi-square test was used if necessary. Results: The most frequently asked questions were discomfort and dissatisfaction after the treatment. The need for treatment was the second in questions of the wisdom tooth extraction and endodontic treatment, but the health insurance benefit was the second in dental scaling. Most of the questioners didn't disclose personal information. The public answered the most in 2013~2014, but the highest percentage of the respondents was experts in 2017. Responses were mostly personal experience, but showed a tendency to decrease with years, and professional knowledge showed an increasing tendency. The error of the answer has also gradually decreased. Conclusion: Questions about dental care over the Internet are increasing exponentially, experts are responding increasingly, and errors in answers are decreasing. Nevertheless, it is necessary to pay attention to the related expert group to prevent misinformation.
