The concept of the Hospital run for medical treatment changing to the forms of theme complex hospital with design by the impact of a boutique design. Especially, this design's element emboss with strongly to form a ring around the special hospital as the dentistry, dermatology and plastic surgery, the woman hospital of a lying-in hospital etc. that is the higher value-added industrial among groups of medical, even general hospital that is not depend on the design relatively, the application of the interior design is extending farther. Also, this special hospital shape up become bigger, form a group and competition for admission to medical industry. For dentistry, the more departmentalize and definite service as implant, children dental clinic holding an absolute dominant position about management, and effective environmental exchange can be essential element for the most profits. Accordingly, In this study I would like to see about the space composition of the dentistry that changing with the times, suggest direction from now on the bigger, specialization and a characteristic of a space focused on recently dentistry project.

Medical science is an area of study that focuses on maintaining health and treating disease. However, modern medicine focuses on treating disease and neglects methodology of maintaining health. Although the definition of heal this defined by the World Health Organization (WHO) and as the concept of harmonizing Yin and Yang in Korean medicine, there is no specific details regarding the definition. Thus, the following conclusion was obtained after the concept of health is viewed through Yin-Yang(陰陽), Vital Essence(精), Qi(氣), and Healthy Person(平人). Although Yin and Yang have opposite properties, they work very closely, maintaining the overall balance and harmony. Secondly, Vin and Yang would each function by the effects of one another, and the body could maintain normal physiological activities through this function. Thirdly, it maintains normal physiological state through the ascending Kidney-Water and descending Heart-Yang(水升火降). Fourthly, Vital Essence is divided into the congenital Essence(先天之精) and the acquired Essence(後天之精) in which the former is related with reproduction and the latter, nourishing. Fifthly, Qi is resistant to pathogens and related with the physique so that Qi and physique should be balanced. Sixthly, Healthy Person is the state where the exchange of Qi-Blood is active.

COVID-19 poses a major risk to global health, highlighting the importance of faster and proper diagnosis. To handle the rise in the number of patients and eliminate redundant tests, healthcare information exchange and medical data are transmitted between healthcare centres. Medical data sharing helps speed up patient treatment; consequently, exchanging healthcare data is the requirement of the present era. Since healthcare professionals share data through the internet, security remains a critical challenge, which needs to be addressed. During the COVID-19 pandemic, computed tomography (CT) and X-ray images play a vital part in the diagnosis process, constituting information that needs to be shared among hospitals. Encryption and image steganography techniques can be employed to achieve secure data transmission of COVID-19 images. This study presents a new encryption with the image steganography model for secure data transmission (EIS-SDT) for COVID-19 diagnosis. The EIS-SDT model uses a multilevel discrete wavelet transform for image decomposition and Manta Ray Foraging Optimization algorithm for optimal pixel selection. The EIS-SDT method uses a double logistic chaotic map (DLCM) is employed for secret image encryption. The application of the DLCM-based encryption procedure provides an additional level of security to the image steganography technique. An extensive simulation results analysis ensures the effective performance of the EIS-SDT model and the results are investigated under several evaluation parameters. The outcome indicates that the EIS-SDT model has outperformed the existing methods considerably.

배 경 : 부분액체환기 (partial liquid ventilation; PLV) 시 최적의 기계환기의 설정에 대해서는 아직 논란이 많은 상태이다. 이에 정상 폐의 PLV 시 가스교환에 영향을 주는 인자들을 관찰함으로써, PLV 시 최적의 기계환기 설정을 확립하는 데에 이용하고자 본 연구를 시행하였다. 방 법 : New Zealand 산 백색 토끼 7 마리를 기계환기를 시행하였다. 기계환기는 압력 조절 양식으로 일회호흡량 ($V_T$) 8 mL/kg, PEEP 4 $cmH_2O$, 흡기대호기비 (I: E ratio) 1:2, 흡입산소분율 ($F_IO_2$) 0.75로 설정하였고, 호흡수(RR)는 $PaCO_2$가 35~45 mmHg 사이에 유지되도록 조절하였다. 이후 30분마다 기계환기기의 설정을 protocol에 따라 변화시키면서 가스환기(gas ventilation; GV)를 시행하였는데 ; (1) 기저 설정 단계, (2) 역비환기 (inverse I: E ratio) 단계로 I:E ratio 2:1, (3) 고 PEEP 단계로 2단계와 같은 평균흡기압 (MIP)을 유지하는 정도의 PEEP 증가, (4) 고 $V_T$ 단계로 $V_T$ 15 mL/kg, (5) 고RR 단계로 4단계와 같은 분당환기량 (MV)을 유지하는 정도로 RR을 증가시켰다. 그 후 perfluorodecalin 18 mL/kg 주입 후 상기 protocol과 동일하게 PLV를 하였다. 각각에서 동맥혈가스검사와 폐역학 및 혈역학적 지표를 측정하였다. 결 과 : (1) GV 시 $PaO_2$는 다섯 단계를 거치는 동안 의미 있는 변화를 보이지 않았다. $PaCO_2$는 고 $V_T$단계와 고 RR 단계에서 의미 있게 감소하였다(p<0.05). GV 시 폐역학 및 혈역학적 지표의 의미 있는 변화는 보이지 않았다. (2) PLV 군의 기저 $PaO_2$는 $312{\pm}113$ mmHg로 GV군의 $504{\pm}81$ mmHg 에 비해 의미 있게 낮았다(p=0.001). PLV 시 역비환기 단계나 고 RR 단계에서는 기저설정 단계와 비교하여 $PaO_2$의 의미 있는 차이가 관찰되지 않았으나, 고 PEEP 단계 ($452{\pm}38$ mmHg)와 고 $V_T$($461{\pm}53$ mmHg) 단계에서는 기저설정 단계보다 유의한 상승이 관찰되었다. (3) $PaCO_2$는 GV군과 PLV군 모두에서 고 $V_T$ 단계와 고 RR 단계에서 기저설정 단계보다 의미 있게 낮았다. PLV군의 기저설정 단계와 고 RR 단계의 $PaCO_2$는 GV 군보다 의미 있게 증가하였다(p<0.05). (4) PLV 시 폐역학 및 혈역학적 지표의 의미 있는 변화는 보이지 않았다 결 론 : 정상 폐에서 PLV 시 최적의 가스교환을 위해서는 적절한 PEEP과 $V_T$이 중용할 것으로 사료된다.

This study was performed to investigate the supply and demand of the oriental medical doctor(OMD) based on the supply and demand analysis of OMD up to the year 1997. The baseline projection and demographic methods were considered to examine the supply of OMD. On the contrary, for the demand analysis, two different approaches were conducted with the nonlinear regression model. The findings of this study indicate that the OMD will be oversupplied before the year 2012 with decreasing rate. However, when we consider the demand of OMD in the future. it is anticipated that the demand of oriental medicine will be increased rapidly with two major aspects. The first is the expansion of insurance benefits. The second is the increasing number of adult diseases because of the aging of the population structure. Therefore, the effective cooperation system and mutual exchange between western and oriental medicine is required for the future. Also. it is necessary to make the oriental medicine of the pharmaceutical services in more scientific way for the appropriate policy of the demand and supply of OMD. For the future study, the students who study abroad, especially China should be considered. These students will be the key element for the future supply of OMD.

Total ginsenosides were purified and their antioxidant, antibacterial and anticancer activities were measured. The crude extracts of ginseng, which were extracted with 75% ethanol by ultrasonification method, were firstly purified on AB-8 macroporous adsorption column to remove water soluble impurities, and decolored on Amberlite IRA 900 Cl anion-exchange column. Then, they were purified on Amberlite XAD16 adsorption column to delete the non-polar impurities. Total ginsenosides contents of the purified extracts were 79.4%, 71.7% and 72.5% in cultured wild ginseng, red ginseng and white ginseng, which were significantly increased than those of crude extracts. All of the three extracts showed concentration-dependant scavenging activities against DPPH radicals, among which white ginseng showed the most powerful activity. Cultured wild ginseng roots showed strongest effect against both B. subtilis PM 125(Gram-positive) and E. coli D31 (Gram-negative) bacteria, while red ginseng and white ginseng only showed the activity against B. subtilis. According to the result of the MTT assay, ail of the three extracts inhibited the growth of U-937 human hohistiocytic lympma cell, which were significantly different (p < 0.05) when compared to the control.

Background: The rise in national health care costs has emerged as a global problem given the ever-aging population and rapid development of medical technology. The utilization of interventional pain management has, similarly, shown a continued rise worldwide. This study evaluates the differences in the medical costs in the field of interventional pain treatment (IPT) between two countries: Korea and Japan. Methods: Korean medical insurance costs for 2019 related to pain management focused on IPT were compared to those of Japan. Purchasing power parity (PPP) was used to adjust the exchange rate differences and to compare prices in consideration of the respective societies' economic power. Results: The cost of trigger point injections in Japan was 1.06 times higher than that of Korea, whereas the perineural and intraarticular injection prices were lower in Japan. The cost of epidural blocks was higher in Japan compared to Korea in both cervical/thoracic and lumbar regions. As for blocks of peripheral branches of spinal nerves, the cost of scapular nerve blocks in Japan was lower than that in Korea, given a PPP ratio 0.09. For nerve blocks in which fluoroscopy guidance is mandatory, the costs of epidurography in Japan were greater than those in Korea, given a PPP ratio 1.04. Conclusions: This is the first comparative study focusing on the medical costs related to IPT between Korea and Japan, which reveals that the costs differed along various categories. Further comparisons reflecting more diverse countries and socio-economic aspects will be required.

우리나라에서 통상 사용하는 협진의 의미는 동일한 의료기관 내에서 서로 다른 진료과목의 의사가 환자를 함께 치료하는 경우로 이해된다. 그렇기 때문에 협진은 다양한 의료관여자들이 각자의 전문성에 의거하여 역할을 분담하여 환자를 치료하는 의료팀의 양상을 띠게 된다. 또한 의료팀 내 다른 진료과목의 의사는 동등한 지위에서 각각 전문성에 의거하여 수평적 분업을 하게 되므로 협진은 분업의 원칙에 따라 법적 책임이 분배된다. 대법원도 "여러 명의 의사가 분업이나 협업을 통하여 의료행위를 담당하는 경우 먼저 환자를 담당했던 의사는 이후 환자를 담당할 의사에게 환자의 상태를 정확하게 알려 적절한 조치를 할 수 있도록 해야 한다."고 하여 의료팀을 이루어 환자를 함께 치료하는 경우를 인정하고, 의사의 협진의무에 대하여 판단하고 있다. 다수의 진료과목이 있는 의료기관 내에서 서로 다른 진료과목의 의사가 분업이나 협업을 통하여 의료행위를 담당하게 되는 협진의 경우, 환자를 담당했던 의사는 환자의 상태에 따라 협진 여부를 결정하여야 하며, 이후 환자를 담당할 진료과목의 의사에게 환자의 상태를 정확하게 알려 적절한 조치를 취하게 하여야 한다. 협진을 하게 된 후임 의사 또한 환자에 대한 치료 종료 시까지 협진을 요청했던 전임 의사에 대하여 환자의 상태와 관련된 치료사항을 적극적으로 고지하고 서로 소견을 교환하여야 할 것이다. 다만 협진의 필요성에 대한 결정은 당시 환자의 상태에 따라 판단이 이루어져야 하는 것으로, 모든 경우에 협진의무가 강제되는 것이라고 단언할 수는 없다. 그리고 협진의 필요성에 대한 결정에 있어서 과실이 존재하는지 여부는 의사의 주의의무 판단에 대한 법리가 적용될 것이다.
