Objectives: We reviewed digital epidemiological studies to characterize how researchers are using digital data by topic domain, study purpose, data source, and analytic method. Methods: We reviewed research articles published within the last decade that used digital data to answer epidemiological research questions. Data were abstracted from these articles using a data collection tool that we developed. Finally, we summarized the characteristics of the digital epidemiological studies. Results: We identified six main topic domains: infectious diseases (58.7%), non-communicable diseases (29.4%), mental health and substance use (8.3%), general population behavior (4.6%), environmental, dietary, and lifestyle (4.6%), and vital status (0.9%). We identified four categories for the study purpose: description (22.9%), exploration (34.9%), explanation (27.5%), and prediction and control (14.7%). We identified eight categories for the data sources: web search query (52.3%), social media posts (31.2%), web portal posts (11.9%), webpage access logs (7.3%), images (7.3%), mobile phone network data (1.8%), global positioning system data (1.8%), and others (2.8%). Of these, 50.5% used correlation analyses, 41.3% regression analyses, 25.6% machine learning, and 19.3% descriptive analyses. Conclusions: Digital data collected for non-epidemiological purposes are being used to study health phenomena in a variety of topic domains. Digital epidemiology requires access to large datasets and advanced analytics. Ensuring open access is clearly at odds with the desire to have as little personal data as possible in these large datasets to protect privacy. Establishment of data cooperatives with restricted access may be a solution to this dilemma.

본 연구의 목적은 코로나-19가 몰고 온 갑작스러운 환경변화 중 여행산업의 변화에 있어서 가장 핵심이 될 디지털 건강/면역 여권(DHP, Digital Health Passport)에 대한 접근법을 제시하기 위해 수행되었다. 이를 위해, 최근 DHP에 관한 다양한 실증적 문헌 고찰을 통해 DHP에 대한 프레임워크를 제안했다. 본 프레임워크는 크게 여행 의도, 건강정보 제공 의도, 신기술 채택·수용 등으로 구성된다. 첫째, 여행 의도의 관점에서, DHP에 정보를 제공하는 것이 여행자의 여행 의도를 훼손하지 않아야 한다. 여행자로부터 받은 정보를 활용하여 여행자의 여행 즐거움을 배증 할 수 있어야 한다. 또한, 여행자에게 받은 데이터가 신뢰할 수 있는 방법으로 관리된다는 것을 확신시켜줄 필요가 있다. 둘째, 건강 관련 정보를 의무적 정보 제공의 관점에서만 보지 말고 여행자가 자신의 개인정보를 제공함으로써 얻을 수 있는 것이 무엇인지 인지시킬 필요가 있다. 마지막으로, 신기술의 관점에서 DHP에 대한 여행자들의 활용·수용 의도를 이해할 필요가 있다. 본 연구는 트래블 버블(Travel Bubble)을 실현하는 데 있어서 핵심기술인 DHP에 대한 여행자들의 반응을 예측하고 대응할 방안을 제안했다는 점에서 의의가 있다.

In this paper, the electric properties of amorphous selenium specimen has been investigated. Amorphous selenium was thermally evaporated on the glass plate which had been deposited onto the interface by aluminium as an electrode. On the surface of the amorphous selenium, the aluminium electrode was deposited again in order to make an unit cell for dark current measurement. The dark current was measured while applying the bias voltage across the selenium layer in the range of 0V-2500 Volts. The leakage property of the amorphous selenium was significantly low at even high voltage range so it has good advantage as a X-ray receptor for digital radiography. For further study, the C-V curves measurement according to thicker amorphous selenium layer.

디지털 TV에서 시멘틱 환경의 유헬스 개인화 서비스 추천은 개인의 신체조건, 질병, 건강상태를 평가해서 이루어져야 한다. 기존의 시멘틱 환경의 유헬스 개인화 추천 방법은 온톨로지에 의존하여 의미 분석으로 추천을 하기 때문에 사용자 만족도가 떨어진다. 이에 본 논문에서는 디지털 TV에서 시멘틱 환경의 유헬스 서비스를 위한 나이브 베이지안 필터링 기반 개인화 서비스 추천 방법을 제안한다. 제안하는 방법은 온톨로지를 이용하여 상황데이터를 추론하여 트렌젝션을 저장 하고, 선호도 정보를 이용한 나이브 베이지안 필터링 기법을 사용하여 온톨로지로부터 생성된 트렌젝션과 사용자 선호도 정보를 이용하여 추론하여 서비스를 제공한다. 나이브 베이지안 필터링 기반으로 추론된 서비스는 기존의 필터링 방법 보다 콘텐츠 추천의 높은 정확도와 재현율을 보인다.

Rapid integration of information technology into health care systems has included the use of highly portable systems-in particular, personal digital assistants (PDAs). With their large built-in memories, fast processors, wireless connectivity, multimedia capacity, and large library of applications, PDAs have been widely adopted by physicians and nurses for patient tracking, disease management, medical references and drug information, enhancing quality of health care. Many health-related PDA applications are available to both dietetics professionals and clients. Dietetics professionals can effectively use PDAs for client tracking and support, accessing to hospital database or information, and providing better self-monitoring tools to clients. Internship programs for dietetics professionals should include training in the use of PDAs and their dietetics applications, so that new practitioners can stay abreast of this rapidly evolving technology. Several considerations to keep in mind in selecting a PDA and its applications are discussed.

Objectives: This study aimed to evaluate digital interventions on psychological well-being in patients with cancer through an integrated review. Methods: Fifteen studies were selected using PubMed, CINAHL, Scopus, DBpia, and RISS. The Scottish Intercollegiate Guidelines Network was used by two reviewers to evaluate independently the quality of the selected articles. Results: Digital interventions for improving psychological well-being in cancer patients were most often based on cognitive behavioral therapy alone or a combination of interventions with professionals and other patients. In addition, a number of interventions were established on internet-based mindfulness therapy. Conclusions: Providing cognitive behavioral intervention alone did not significantly improve the level of depression or anxiety of patients with cancer. Meanwhile, interventions, including cognitive behavior therapy and interactions with professionals and other patients, were found to reduce significantly the level of depression or anxiety in the experimental group.

One of the most negative social changes of the last decade is population aging which leads to 19 times more patients with Mild Cognitive Disorder(MCI). It is well established that MCI is the most important state that can prevent dementia with early diagnosis and intervention. However, the social security system for patients with dementia is not working properly due to the coronavirus pandemic and the limited human power. This article proposes a form of workbench and design principles for dementia training programs of extended reality devices. and the findings in this study provide a guide for considering the cognitive and physical and social functions of patients.

This study aims to investigate how health belief of adult female users of the health training center affect health-promoting behavior through self-efficacy and exercise satisfaction. The proposed model is based on health belief model of Rosenstock et al. To validate the proposed model, PLS analysis is performed with the valid 177 questionnaires collected from Seoul and nearby cities. The results are as follows. First, perceived severity has a positive effect on self-efficacy, not on exercise satisfaction. Second, perceived susceptibility does not has a positive effect on both self-efficacy and exercise satisfaction. Third, perceived barriers has a positive effect on self-efficacy, not on exercise satisfaction. Fourth, perceived susceptibility has a positive effect on both self-efficacy and exercise satisfaction. Fifth, self-efficacy has a positive effect on exercise satisfaction and health-promoting behavior. Sixth, exercise satisfaction has a positive effect on health promoting behavior.
