The rapid development of artificial intelligence (AI), including deep learning, has led to the development of technologies that may assist in the diagnosis and treatment of diseases, prediction of disease risk and prognosis, health index monitoring, drug development, and healthcare management and administration. However, in order for AI technology to improve the quality of medical care, technical problems and the efficacy of algorithms should be evaluated in real clinical environments rather than the environment in which algorithms are developed. Further consideration should be given to whether these models can improve the quality of medical care and clinical outcomes of patients. In addition, the development of regulatory systems to secure the safety of AI medical technology, the ethical and legal issues related to the proliferation of AI technology, and the impacts on the relationship with patients also need to be addressed. Systematic training of healthcare personnel is needed to enable adaption to the rapid changes in the healthcare environment. An overall review and revision of undergraduate medical curriculum is required to enable extraction of significant information from rapidly expanding medical information, data science literacy, empathy/compassion for patients, and communication among various healthcare providers. Specialized postgraduate AI education programs for each medical specialty are needed to develop proper utilization of AI models in clinical practice.

The present study examined a moving bed biofilm reactor (MBBR) bioreactor on a laboratory scale for simultaneous removal of atrazine, organic carbon, and nutrients from wastewater. The maximum removal efficiency of atrazine, chemical oxygen demand (COD), total phosphorus (TP) and total nitrogen (TN) were 83.57%, 90.36%, 90.74% and 87.93 respectively. Increasing salinity up to 40 g/L NaCl in influent flow could inhibit atrazine biodegradation process strongly in the MBBR reactor.Results showed that MBBR is so suitable process for efficiently biodegrading of atrazine and nitrogen removal process was based on the simultaneous nitrification-denitrification (SND) process.

For more than 2,500 years, surgical teaching has been based on the so called "see one, do one, teach one" paradigm, in which the surgical trainee learns by operating on patients under close supervision of peers and superiors. However, higher demands on the quality of patient care and rising malpractice costs have made it increasingly risky to train on patients. Minimally invasive surgery, in particular, has made it more difficult for an instructor to demonstrate the required manual skills. It has been recognized that, similar to flight simulators for pilots, virtual reality (VR) based surgical simulators promise a safer and more comprehensive way to train manual skills of medical personnel in general and surgeons in particular. One of the major challenges in the development of VR-based surgical trainers is the real-time and realistic simulation of interactions between surgical instruments and biological tissues. It involves multi-disciplinary research areas including soft tissue mechanical behavior, tool-tissue contact mechanics, computer haptics, computer graphics and robotics integrated into VR-based training systems. The research described in this paper addresses the problem of characterizing soft tissue properties for medical virtual environments. A system to measure in vivo mechanical properties of soft tissues was designed, and eleven sets of animal experiments were performed to measure in vivo and in vitro biomechanical properties of porcine intra-abdominal organs. Viscoelastic tissue parameters were then extracted by matching finite element model predictions with the empirical data. Finally, the tissue parameters were combined with geometric organ models segmented from the Visible Human Dataset and integrated into a minimally invasive surgical simulation system consisting of haptic interface devices and a graphic display.

WBAN은 사람이 착용하는 옷이나 인체 내부 혹은 외부에 있는 여러 장치들을 상호 연결하여 통신할 수 있는 근거리 무선통신 기술이다. WBAN은 기술 적용 분야에 따라 의료용과 비의료용으로 구분할 수 있으며, 주기적인 특성을 가진 의료용 데이터의 경우 GTS 방식을 사용해서 데이터를 전송하여 QoS를 보장한다. 본 논문에서는 WBAN 슈퍼프레임 구조에서 GTS 방식으로 데이터를 전송시 부족한 GTS 타임 슬롯을 해결하는 알고리즘을 제안한다. 코디네이터는 디바이스의 데이터 전송률에 따라 GTS 타임 슬롯을 가변적으로 할당하며, GTS의 개수가 부족하면 GTS 타임 슬롯을 공유하여 사용하도록 할당한다. 제안한 기법의 성능평가를 위해 지연한도와 처리량을 비교하였다. 즉, WBAN 환경에 적합한 WFQ(Weighted Fair Queuing) 스케줄링을 적용하여 상이한 데이터 전송률을 지원하면서 GTS를 할당하는 방법을 제안하였고, 라운드로빈(Round Robin) 스케줄링 방법과 비교하여 처리량은 증가하면서 최대 지연이 감소함을 알 수 있다.

The aim of this study is to provide the background of developing guides to clinical performance and basic clinical skills and to introduce how to teach and learn using the guide. The students' performance problems presented in an objective clinical skills examination were disease-centered tertiary hospital clinical care, incomplete performance, doing by rote, and an exam-oriented learning attitude. The problems were caused by a tertiary hospital-based educational environment as well as schools and faculty who are unfamiliar with the concept of patient-centered care. The purpose of the guide to clinical performance and basic clinical skills is to overcome these problems and address the causes. The guides show a clinical presentation approach to primary care; clinical care integrated with knowledge, skills, and attitude; a schematic approach; and a patient-centered attitude. To achieve these goals, a strategy to change the educational culture is important. Curricular reform, faculty development, and improving educational facilities and environments are suggested.

Traditional Knowledge[TK] is a concept which summings up all the knowledge of traditionally inherited, includes traditional medicine, therapy, food and environments. Such traditional knowledge has been perished and neglected through industrial development. We, Korean Institute of Oriental Medicine, promotes digitalization of this traditional knowledge to support and maximize its application, principally in Traditional korean medicine. We can get opportunity of reorganize the traditional knowledge to more practical and available form by this project. And also we introduce briefly its meaning and worth, and seek for application to the study of medical history.

The WBAN(Wireless Body Area Network) supplies mobile convenience to our medical services. But if we have few effective control variables across this service deployment, the hidden distortions or defects of the system might threaten the lives and rights of the stakeholders. Therefore we need to increase the service credibility, to get WBAN effective. This study proposes a governance mechanism using feasible variables that are currently in use in practices in WBAN environments against medical incidents. Control variables were tested in Seoul National University hospital and related medical industries of South Korea. We assume that WBAN systems would be open based on integrating patients, medical employees and law enforcements to get smart theater operations against medical incidents by implementing proposed MJA(Multilateral Joint Analysis) model. MJA model also contributes to the convergence of computer systems and medical services by demonstrating flexible SOA(Service Oriented Architecture) dashboard of healthcare services with credibility factors in medicine. The important components in MJA model across WBAN, were found to be "Safety, Accuracy and Reliability" in priority order. Factor analysis, correlations and ANOVA were used to evaluate this model and an IT dashboard with a realization of mobile application, was used to support participants' decision-making.
