본 논문에서는 사람들의 안전하고, 편리한 생활을 위한 스마트 홈을 목표로 ESP32와 RFID, 라즈베리 파이를 이용한 구글 클라우드, 네오픽셀 등을 이용해 문이 열림과 동시에 사용자에게 문자 메시지 전송, 스마트 AI를 이용한 다양한 정보제공 및 일정관리, 네오픽셀을 이용하여 음악 감상 등의 상황에서 분위기에 맞는 조명의 밝기 및 분위기의 제공같이 직관적이고 일상생활에서 간편한 활용이 가능한 스마트 홈 시스템을 설계하였다. 실험결과 전원이 재 연결 되도 Wi-Fi와 연결된 ESP32에서 RFID가 인식될 때 보안문자가 정상적으로 사용자에게 전송되는 것을 확인하였고, 주파수를 계산한 네오픽셀의 조명 및 라즈베리파이와 음성인식을 이용한 스마트 AI또한 거리에 따라 인식률의 변화가 있지만 작동됨을 확인하였다. In this paper, we designed a smart home system that can be used intuitively and easily in everyday life, such as sending text messages to users, providing various information and scheduling using smart AI, and providing lighting and atmosphere suitable for the atmosphere in situations such as listening to music using neopixels, as well as using ESP32, RFID, and Google Cloude Console using raspberry pie. As a result of the experiment, it was confirmed that security characters were normally sent to users when RFID was recognized on ESP32 connected to Wi-Fi even if the power was reconnected, and smart AI using Neopixel lighting, Raspberry Pie, and voice recognition, which calculated frequency, also changed the recognition rate over distance, but it worked.

Thyrotoxic periodic paralysis occurs primarily in Orientals with an overwhelming male preponderance and a higher association of specific HLA antigens. Clinical manifestations include onset after high carbohydrate ingestion or heavy exertion with progressive symmetric weakness leading to flaccid paralysis of the extremities and other muscle groups, lasting several hours. Other precipitating facters include trauma, infection, administration of epinephrine, thyroid hormone, or corticosteroid. If hypokalemia is present, potassium administration may help abort the attack. Although propranolol can be efficacious in preventing further episodes, the only definitive treatment is euthyroid state. The pathophysiology is still controversal, but reflects altered potassium and calcium dynamics as well as certain morphologic characteristics within the muscle unit itself. We discribed two patients with thyrotoxic periodic paralysis who had a no familial history of paralysis and had a decreased level of serum potassium during attack.

We reviewed retrospectively 230 patients who came to emergency room of Kang Nam St. Mary's Hospital and Uijongbu St. Mary's Hospital between 1. January and 31. December 1994. We classified them according to their age, sex, a sort of drug, the cause of poisoning, prehospital care, time-lapse to arrive at hospital after poisoning, psychiatric problem the status of patients. *We conclude as follows; 1. The male to female ratio was totally 1 : 1.98, 1 : 1.24 in a urban area, 1 : 2.43 in a rural area. 2. On age of the patients in this study, the peake incidence was between 20 and 39(55.2%). 3. On seasonal prevalence, the poisoning was most common in summer and spring, in urban area(35.7%) and rural area(37.0%) respectively. 4. The common drug were as follow; Doxylamine, Organophosphate, Acetaminophen in urban area, Paraquat, Organophospate, Doxylamine in rural area 5. The percentage of suicidal attempt were 81.8% and 87.7% in urban area and rural area respectively. 6. The poisoning patients had psychatric problem in 19.4% and 24.6%, in urban area and rural area respectively. 7. Before arrival to emergency room, 27.7% of patient was done prehospital care in rural area. 8. On arrival to emergency room, 95.1% and 73.8% of patients show stable vital sign in urban area and rural area respectively.

Torsades de pointes is a form of polymorphic ventricular tachycardia that is associated with prolongation of the QT interval, characterized by QRS complexes of progressively changing amplitude and contour that seem to revolve around the isoelectric line. The most common cause of Torsades de pointes induced by antiarrhythmic agents, occupying in certain drugs or toxin, electrolyte disturbance, congenital QT prolongation syndrome. Cardiotoxicity terfenadine, in overdose a widely used, nonsedating antihistamine, has been reported. Case after administration of terfenadine and ketoconazole causing syncope and torsades de pointes have been reported in recommended dose. We report a case of QT prolongation with torsades de pointes after therapeutic administration of terfenadine, a long acting histamine H1 receptor antagonist, together with ketoconazole, an antifungal preparation. The patient is a 43-year-old female, who experienced palpitation, dizziness and syncopal episoders after coadministration of terfenadine and ketoconazole, for a fungal infection of the skin. The ECG showing typical episodes of torsades de pointes with QT prolongation. Magnesium sulfate was given, torsades de pointes did not recur. The patient was discharged with improved condition.
