This literature review explores artificial intelligence (AI) technology trends and IBM Watson health and medical references. This study explains how healthcare will be changed by the evolution of AI technology, and also summarizes key technologies in AI, specifically the technology of IBM Watson. We look at this issue from the perspective of 'information overload,' in that medical literature doubles every three years, with approximately 700,000 new scientific articles being published every year, in addition to the explosion of patient data. Estimates are also forecasting a shortage of oncologists, with the demand expected to grow by 42%. Due to this projected shortage, physicians won't likely be able to explore the best treatment options for patients in clinical trials. This issue can be addressed by the AI Watson motivation to solve healthcare industry issues. In addition, the Watson Oncology solution is reviewed from the end user interface point of view. This study also investigates global company platform business to explain how AI and machine learning technology are expanding in the market with use cases. It emphasizes ecosystem partner business models that can support startup and venture businesses including healthcare models. Finally, we identify a need for healthcare company partnerships to be reviewed from the aspect of solution transformation. AI and Watson will change a lot in the healthcare business. This study addresses what we need to prepare for AI, Cognitive Era those are understanding of AI innovation, Cloud Platform business, the importance of data sets, and needs for further enhancement in our knowledge base.

서양사회는 중세를 '암흑시대'로 폄하해 왔다. 그러나 중세 천년을 주도한 이슬람이 종이와 제지술, 아랍 번역본을 서양에 전파하지 않았다면 희랍 라틴어 번역과 전수, 구텐베르크 인쇄술, 종교개혁, 르네상스는 태동할 수 없었다. 그들은 고대 지식문명 파괴자가 아니라 복원과 부활의 주역이었다. 그 거점이 무슬림 공동체로 회자되는 모스크와 이슬람 도서관(지혜의 집)이다. 이에 본 연구는 중세 이슬람 왕조의 성립과 아라비아 반도, 아프리카, 이베리아 반도를 지배하는 과정에서 등장한 이슬람 도서관을 추적했다. 이를 위하여 왕실이 주도한 칼리프 도서관, 모스크에 병설된 공공도서관, 재상과 학자 등이 설립한 개인도서관으로 대별한 후 중세 이슬람 도시인 다마스쿠스, 메카, 바그다드, 알레포, 코르도바, 카이로, 페스, 튀니스 등의 주요 도서관 흔적을 중심으로 역사와 발전, 역할과 기능, 인류문명에 미친 영향과 중요성, 침체와 쇠퇴 등을 분석했다.

Objectives: This review is aimed at assessing the efficacy and effectiveness of oriental medicine for the prevention of Ovarian Hyperstimulation Syndrome (OHSS) through literature research and overview. Methods: Database searching was conducted to identify relevant randomized controlled trials (RCTs) on oriental medicine for the prevention of Ovarian Hyperstimulation Syndrome. Studies were searched from Journal of Korean Obstetrics and Gynecology, Korean studies Information Service System, Korean Medical Database, China National Knowledge Infrastructure, Cochrane library, PubMed and EmBase up to 7^th November, 2019. Results: Ten RCTs were finally selected. Eight studies intervened with oral Chinese herb medicine, one is intervened with Chinese medicine enema and the other with acupuncture. Eight studies concluded that intervention with oriental medicine significantly decreased OHSS incidence. Five studies showed significantly higher pregnancy rate in the intervention groups. Two studies reported higher ovulation rate and other two studies showed more maturated eggs than the control groups. Four studies showed opposite results in serum Estradiol level. Vascular Endothelial Growth Factor level was significantly lower in the intervention groups in two studies. Conclusions: From ten studies, oriental medicine reduced OHSS incidence rate and showed preventable effectiveness. Further strictly designed studies and acupuncture intervened studies are needed to establish evidences.

The information society is characterized by rapidly increasing and changing information. Traditional models of learning and instruct on have emphasized forms of mastering the information in content domains. Storing information and being able to recall it has been central to formal education. But it is no longer possible to master content domains. This paper discusses constructivism as a shifting paradigm for educational research and practice in information society. Constructivism provides an alternative epistemological base to the objectivist tradition. Constructivism holds that there is a real world that we experience. However, the argument is that meaning is imposed on the world by us, rather than existing in the world independently of us. Meaning is seen as rooted in experience. The experience in which an idea is embedded is critical to the individual's understanding of that idea. From the constructivist perspective, learning is not a stimulus-response phenomenon. It requires self-regulation and the building of conceptual structures through reflection and abstraction. Problems are not solved by the retrieval of rote-learned right answers. The effective motivation to continue learning can be fostered by leading students to experience the pleasure that is inherent in solving problems chosen as one's own. Constructivism requires the change of the teacher's role from a knowledge transmitter to a coach or facilitator of student's understanding. Constructivist teachers inquire about students' understanding of concepts before sharing their own understandings of those concepts, and encourage students to engage in dialogue, both with them arid with one another. In Korea, the educational reform called open education has been spreading through out the country. There should be a paradigm shift in learning and instruction from objectivism to constructivism for better educational reform in Korea.

With the advance of Information Technology (IT) and dynamic requirements, diverse application services have been provided for end users. With huge volume of these services and information, users are required to acquire customized services that provide personalized information and decision at particular extent of time. The case is more appealing in healthcare, where patients wish to have access to their medical record where they have control and provided with recommendation on the medical information. PHR (Personal Health Record) is most prevailing initiative that gives secure access on patient record at anytime and anywhere. PHR should also incorporate decision support to help patients in self-management of their diseases. Available PHR system incorporates basic recommendations based on patient routine data. We have proposed decision support service called "Smart CDSS" that provides recommendations on PHR data for diabetic patients. Smart CDSS follows HL7 vMR (Virtual Medical Record) to help in integration with diverse application including PHR. PHR shares patient data with Smart CDSS through standard interfaces that pass through Adaptability Engine (AE). AE transforms the PHR CCR/CCD (Continuity of Care Record/Document) into standard HL7 vMR format. Smart CDSS produces recommendation on PHR datasets based on diabetic knowledge base represented in shareable HL7 Arden Syntax format. The Smart CDSS service is deployed on public cloud over MS Azure environment and PHR is maintaining on private cloud. The system has been evaluated for recommendation for 100 diabetic patients from Saint's Mary Hospital. The recommendations were compared with physicians' guidelines which complement the self-management of the patient.

Rapid developments in technology as part of the Fourth Industrial Revolution have created a demand for educational technology (EdTech) and a gradual transition from traditional teaching and learning to EdTech-assisted learning in medical education. EdTech is a portmanteau (blended word) combining the concepts of education and technology, and it refers to various attempts to solve education-related problems through information and communication technology. The aim of this study was to explore the use of key EdTech applications in medical education programs. A scoping review was conducted by searching three databases (PubMed, CINAHL, and Educational Sources) for articles published from 2000 to June 2021. Twenty-one studies were found that presented relevant descriptions of the effectiveness of EdTech in medical education programs. Studies on the application and effectiveness of EdTech were categorized as follows: (1) artificial intelligence with learner-adaptive evaluation and feedback, (2) augmented/virtual reality for improving learning participation and academic achievement through immersive learning, and (3) social media/social networking services with learner-directed knowledge generation, sharing, and dissemination in medical communities. Although this review reports the effectiveness of EdTech in various medical education programs, the number of studies and the validity of the identified research designs are insufficient to confirm the educational effects of EdTech. Future studies should utilize suitable research designs and examine the instructional objectives achievable by EdTech-based applications to strengthen the evidence base supporting the application of EdTech by medical educators and institutions.
