In order to prevent the spread of COVID 19, the body temperature is measured when entering the building. In this paper, we try to certify the entry of the building through real-time face recognition based on the face learning data of visitors. The number of learning images are designed to be automatically labeled to increase facial recognition. Also, it designates the forehead region from the face region as the region of interest for accurate temperature measurements. In the future, we plan to establish a database that stores the temperature, access time, and information of visitors.

최근 인건비보다 저렴하게 사용할 수 있는 자율주행 로봇에 대한 수요가 증가하고 있다. 팬데믹의 영향으로 마스크 착용과 체온 측정이 의무화되어 키오스크, 체온 측정기와 같은 비대면 서비스의 수요 또한 증가하였다. 하지만 이러한 기능들은 각기 다른 기계에서 독립적으로 사용되며, 현재 보급된 자율주행 로봇을 병원에서 사용하기에는 적합하지 않다고 판단하였다. 본 연구에서 개발한 마스크 착용 여부 확인, 체온 확인, 자율주행을 활용한 안내 기능을 탑재한 인공지능 병원 안내 로봇을 통해 의료진의 업무 효율화 및 잠재적 비용 감소 효과를 기대한다. 본 연구에서는 마스크 착용 여부 확인을 위해 사용한 YOLOv5 알고리즘 훈련 결과를 통하여 높은 성능을 확인하였고 열화상 카메라를 사용한 체온 측정 알고리즘을 개발하였다. 또한, 실내 자율주행 실험을 통하여 Cartographer, Navigation 기능이 정상적으로 작동함을 확인하였다.

Recently, technology of self diagnosis system which one of health-care has been research very active. With this, In this paper, we have to implement the self-blood sugar measurement system that is interlock with PC, RFID, and Bio-Signal glucose tester and accessible user interface. Therefore the equipments can performs accessible interface composition for communication between devices and PC, analysis and test of communication status of the RFID tag and reader that it easy to obtain the data of self-diagnosis linkage with PC, RFID, and Bio-Signal glucose tester. In other words, as result of communication protocol experiment with self-blood sugar measurement data, it has been showed to display a high-reliability result through year, month, and day, body temperature, and levels and check point of blood glucose.

This case report describes the increment of regulatory T cells in thyroid carcinoma of a mixed breed dog compared with normal dogs. A mixed breed dog was referred for a submandibular mass and hyperthermia. Right cervical mass was detected during the physical examination and radiography identified right cervical mass suspected thyroid gland. Accurate location and size of mass was confirmed using computed tomography and 3D reconstructed images. After confirmation of mass, surgical resection was performed and evaluation of regulatory T cells in blood of this patient was performed using flow cytometric assay. The percentage of regulatory T cells was 38.28% of all CD4 (+)/CD25 (+) T cells. This result was higher than median percentage of regulatory T cells of healthy 8 beagles ($7.66{\pm}1.65%$ (p<0.01) of all CD4 (+)/CD25 (+) T cells). And masses were confirmed as giant cell thyroid carcinoma based on histopathologic examination. After surgical resection of cervical mass was performed, the owner didn't want chemotherapy. Seven days later, cervical mass came out again. And CBC showed severe leukocytosis (WBC $47.6{\times}10^3/{\mu}L$) and non-regenerative anemia (PCV 21%). Suspected pulmonic metastasis regions became more severe. Finally the dog died of severe anemia and respiratory disorder.

This study aimed to investigate the autonomic innervations of human vas deferens and the effect of diazepam, a benzodiazepine sedative antianxiety drug, on the smooth muscle contractility of vas deferens. The specimens were obtained from healthy volunteers undergoing elective vasectomy with local anesthesia. The muscle preparation did not show any spontaneous contraction, but showed a good contraction induced by norepinephrine exerting the strongest response at $33^{\circ}C$. Phentolamine inhibited the norepinephrine-induced contraction concentration-dependently. Isoproterenol, a beta-adrenergic agonist evoked a considerable extent of contraction, and this contractile activity was antagonized by propranolol, a beta-adrenergic blocking agent. Acetylcholine induced a dashing contraction of the human vas deferens, and atropine, a muscarinic receptor blocking agent abolished the acetylcholine-induced contraction. Diazepam inhibited the norepinephrine-induced contraction in a concentration dependent manner. These results suggest that the smooth muscle of human vas deferens has cholinergic muscarinic and beta adrenergic receptors as well as the predominant alpha adrepergic receptor. Diazepam inhibits the motility, especially norepinephrine-induced contraction of human vas deferens.

Recently due to the enhancement of education and lifestyle, the trend of healthcare services are changed to a more active and differentiated service in which a continuous self health care is possible. The Smart-Telemedicine system offers medical services by merging Blue-tooth and telecommunication modules to former blood pressure, blood sugar, heartbeat and temperature measuring devices. Moreover, it could analyze one's health pattern which would be helpful for the patient to prevent potential future illness. In addition, the easier accesses to various remote controllable medical check-up programs are offered to public as a number of available smart phone are rapidly escalating. The Smart-Telemedicine system provides the most ideal interactive medical service via accessible smart phones and mobile medical check-up devices at anywhere and anytime. It is very beneficial since it can save patients' time and money because people can reach to the service right at their home and be allowed to take charge of their health care process via longitudinal health data. Therefore, not only social costs that occur in elderly community would be saved, but also business in various forms of medical service field transactions could be possible. This paper will suggest the Smart-Telemedicine System for preventive medicine, its design and analysis of business models and the evaluation of those model.

There are some cases in trouble with monitoring emergency patient by existing electrode sensor in measuring instrument in home and hospital etc. And there are problem to measure because of coming down electrode in emergency car or vessel of shaking and fat, humidity of patient. In this study, it has designed band-type for patient to put on the breast easily and go around anywhere freely putting band electrode on his body. Gold has used as electrode material in this electrocardiogram because of its excellent electronic resistance peculiarity and no trouble with skin. And it is able to monitor multi-body-signal by additional design of periphery temperature. There are good results of body signal transmission in the breast or the rib, and get a little body signal in abdomen. We get a result it is better case of gold than usual electrode on signal detection, and know usual electrode was disposable, but we have more correct result from gold electrode sensor, being semi-permanent ana. great contact ability even if movement.
