With growing interest in novel digital healthcare devices, such as artificial intelligence (AI) software for medical diagnosis and prediction, and their potential impacts on healthcare, discussions have taken place regarding the regulatory approval, coverage, and clinical implementation of these devices. Despite their potential, 'digital exceptionalism' (i.e., skipping the rigorous clinical validation of such digital tools) is creating significant concerns for patients and healthcare stakeholders. This white paper presents the positions of the Korean Society of Radiology, a leader in medical imaging and digital medicine, on the clinical validation, regulatory approval, coverage decisions, and clinical implementation of novel digital healthcare devices, especially AI software for medical diagnosis and prediction, and explains the scientific principles underlying those positions. Mere regulatory approval by the Food and Drug Administration of Korea, the United States, or other countries should be distinguished from coverage decisions and widespread clinical implementation, as regulatory approval only indicates that a digital tool is allowed for use in patients, not that the device is beneficial or recommended for patient care. Coverage or widespread clinical adoption of AI software tools should require a thorough clinical validation of safety, high accuracy proven by robust external validation, documented benefits for patient outcomes, and cost-effectiveness. The Korean Society of Radiology puts patients first when considering novel digital healthcare tools, and as an impartial professional organization that follows scientific principles and evidence, strives to provide correct information to the public, make reasonable policy suggestions, and build collaborative partnerships with industry and government for the good of our patients.

국내뿐만 아니라, 전세계적으로 관심을 가지고 있는 인플루엔자 바이러스(influenza virus)는 일반적으로 고열과 기침을 동반한 독감을 일으키는 원인체로서, 사람을 포함한 포유동물과 조류 등에 감염되고 전염될 수 있기 때문에 많은 문제를 유발 하고 있습니다. 또한 이미 많이 알려진 조류 인플루엔자(avain influenza; AI)의 경우 조류에서 뿐만 아니라, 사람에게 전염될 경우 치명적인 결과를 초래하는 경우가 많아 때로는 공포의 대상이 되기도 합니다. 더욱이 조류 인플루엔자(AI)는 보건상의 문제를 해결하기 위해 많은 노력을 기울이고 있음에도 불구하고, 현재까지도 국내.외 여러 산업에 영향을 주거나 사람이 사망에 까지 이르고 있는 실정입니다. 이러한 현실에서 인플루엔자 바이러스가 사람을 비롯한 여러 동물에서 감염 혹은 전염이 확인될 경우 많은 걱정을 할 수 밖에 없으며, 만약 동물에서의 바이러스 감염 사실이 과장되거나 잘못된 정보가 대중에게 알려질 경우에는 사회적으로 엄청난 파장을 일으킬 수 밖에 없는 것이 현실입니다. 더욱이, 근래 미국에서는 개의 독감(canine flu)이라고 불리는 개의 인플루엔자 바이러스(canine influenza virus; CIV) 감염이 전역으로 확산되고 있는 상황이기 때문에, 국내에서도 예의주시하면서 지켜보고 있을 뿐만 아니라, 수의사를 비롯한 보호자를 개의 인플루엔자 바이러스에 대해서 많은 관심을 가지고 있는 상황입니다.

Objectives : To determine the meaning of 'yi(噫)' from verses containing the character in 『Huangdineijing』. Methods : First, examples of the usage of 'yi(噫)' in Huangdineijing were collected and analyzed, followed by examples from the other books of the time when 『Huangdineijing』 was written. Finally the term 'ai' which surfaced in a later period than Huangdineijing to refer to eructation was examined. Results & Conclusions : Based on analysis of the usage of 'yi(噫)' in the 『Huangdineijing』, out of a total of 20 cases, 14 cases could be categorized as referring to eructation, 4 cases were difficult to categorize as eructation, and 2 cases were indeterminable. At the time of publication of 『Huangdineijing』, the character 'yi(噫)' was generally used to refer to eructation when used in a medical context, while in non-medical contexts it referred to sigh, or groan. The appearance of 'ai(噯)' is predicted to be during the Song period, but its appearance did not take away the meaning of eructation from 'yi(噫)' and both were used. Based on the change of meaning of 'yi(噫)', we can determine the approximate time when certain contents of the 『Huangdineijing』 were constructed. In the case of '心爲噫[Heart makes 'yi(噫)']', we can understand it as the pectoral qi leaking through the throat manifesting as a sigh in order to relieve stagnation of the excessiveness of the Heart. In cases of deficiency, when the Stomach function is weak, the body is likely to let out a sigh. The term meaning sighing which is 'taixi(大息)' was understood as symptomatic of problems of the Gallbladder as well as the Heart.

Objective: We determined the risk factors limiting first service conception (FSC) rate in dairy cows and their economic impact. Methods: Data were collected from 790 lactations regarding cow parity, peri- and postpartum disorders, body condition score (BCS), reproductive performance, and expenses associated with reproductive management (treatment, culling, and others). Initially, we identified the risk factors limiting FSC rate in dairy cows. Various biological and environmental factors, such as herd, cow parity, BCS at 1 month postpartum and first artificial insemination (AI), resumption of cyclicity within 1 month of calving, year, AI season, insemination at detected estrus or timed AI, peri- and postpartum disorders, and calving to first AI interval, were evaluated. Next, we evaluated the economic impact of the success or failure of FSC by comparing the expense associated with reproductive management until conception between cows that did or did not conceive at their first service. Results: Cows with BCS <3.0 had a lower probability of conceiving at first insemination (odds ratio [OR] = 0.64, p<0.05) than cows with $BCS{\geq}3.0$. Cows inseminated during summer were less likely to conceive (OR = 0.44, p<0.001) than cows inseminated during spring. Cows with peri- or postpartum disorders were less likely to conceive (OR = 0.55, p<0.001) than cows without disorders. Survival curves generated using MedCalc showed an 81 day extension in the mean interval between calving and conception in cows that failed to conceive over those that did conceive at first insemination. Cows failing conceive required additional expenditure on reproductive treatment ($55.40) and other management ($567.00) than cows that conceived at first insemination. Conclusion: Lower BCS, hot weather at first insemination, and peri- and postpartum disorders are risk factors limiting FSC, which result in an economic loss of $622.40 per dairy cow.
