Objectives: The purpose of this study was to analyze the medical cost of facial paralysis in payer perspective and to estimate the practice pattern of patient using 2011 Health Insurance Review & Assessment Service-National Patients Sample(HIRA-NPS). Methods: Basic statistical system was used for descriptive analysis of NPS dataset. A table for general information (table20) was extracted by disease code, and social demographic characteristics, distribution of the use among inpatients and outpatients, utilization of each kind of medical care institutions, medical cost were analyzed. Subgroup analysis was conducted for assuming the practice pattern of korean medicine and western medicine. Results: A total of 8,219 people and 64,345 claims data were identified as having facial paralysis. Proportion of outpatient was 95.23%, inpatient 0.84% and patient using both services 3.93%. Mean patient charges was 44,229 won per outpatient, 178,886 won per inpatient and 523,542 won per patient using both services. Utilization of korean medical care institutions was 68.81%(claims), 40.46%(patients), utilization of western medical care institutions was 31.19%(claims), 59.54%(patients). The amount charged by korean medical care institutions was 52.61% and western medical care institutions was 47.39%. Cost per claim was higher than those of the korean treatment and cost per patient of western treatment was lower than those of the korean treatment. Conclusions: The research assessed the medical cost and practice pattern associated with facial paralysis. These findings could be used in health care policy and subsequent studies.

The location of BL61 has commonly known as directly under the BL60 (Gollyun) which is at the lateral side of the heel. SP2 is located at the front of the big toe joint and SP3 is located at the rear of the big toe joint. These locations are the same with the standard acupuncture points of the WHO/WPRO. However, according to Chimgeumdongin (鍼金銅人), BL61 is located at the center of calcaneal tuberosity, which is close to the bottom of the heel, not at the side. SP2 is located at the rear of the big toe joint, not at the front. SP3 is located at the rear of sesamoid bone, not at the rear of the big toe joint. These can be also found in Douningyou (銅人形) c-544 with the same locations. Moreover, these locations are precisely equal in reference to the acupuncture classics such as < Zhenjiujiayijing : 鍼灸甲乙經 >, < Buzhutongrenjing : 補註銅人經 >, whereas the descriptions of the standard acupuncture points of the WHO/WPRO and the locations of acupuncture points in Zhenjiutongren (鍼灸銅人), Zhinjiuxueweitongren (鍼灸穴位銅人) are totally different from the acupuncture classics. Therefore, there needs to be further examinations on WHO/WPRO Standard Acupuncture Point with various acupuncture bronze men.

According to the recent research results of the Ministry of Environment, the indoor air quality of large general hospitals and university hospitals(58 hospitals) exceeded the maintenance standard. On top of such indoor air quality, it is also desperately required to have the environment-friendly building design and also low carbon green design in accordance with the increase of hospital size and enlarged hospital buildings. Especially, the increase of carbon dioxide, heat, garbage, waste energy, exhaust heat from power plants and sewage heat in each medical center brings up lots of problems to the health of hospital patients and customers. Thus this study aims to convergently develop the green environment-friendly architecture design technology concerning the organic relations between each medical building, and technical development which should be introduced to the low carbon green environment-friendly architecture design based on the characteristics of each medical center in large-scale medical complex.

최근 생활습관정보는 대사증후군을 진단하기 위한 임상적 진단지표로 중요하게 활용되고 있다. 대사증후군은 심혈관 및 간질환 그리고 당뇨와 같은 여러 합병증을 유발할 수 있는 질환으로 질환 정도에 따른 체계적 관리가 필요하다. 그러나 대사증후군 환자의 생활습관을 수집하기 위한 대부분의 시스템은 자가진단 및 예방 중심의 시스템으로 구성되어 있어 정확한 생활습관을 수집하여 생활습관을 관리하기에는 어려움이 있다. 본 논문에서 제안하는 시스템은 임상적 진단지표에 도움이 될 수 있도록 신뢰성 있는 생활습관 정보를 수집하기 위한 방법을 제시하고 수집된 생활습관정보를 모니터링 하여 환자의 생활습관 개선 여부에 따라 지속적인 피드백을 제공하여 체계적으로 생활습관을 관리할 수 있는 시스템을 제안하고자 한다.

Radiomics and deep learning have recently gained attention in the imaging assessment of various liver diseases. Recent research has demonstrated the potential utility of radiomics and deep learning in staging liver fibroses, detecting portal hypertension, characterizing focal hepatic lesions, prognosticating malignant hepatic tumors, and segmenting the liver and liver tumors. In this review, we outline the basic technical aspects of radiomics and deep learning and summarize recent investigations of the application of these techniques in liver disease.

Purpose: This study aims to explore the feasibility of expanding complex wards to provide efficient hospital management and high-quality medical services to local residents of Gangneung Medical Center (GMC). Research Design, Data and Methodology: There are four research designs to achieve the research objectives. We analyzed Big Data for 3 months on Social Network Services (SNS). A questionnaire survey conducted on 219 patients visiting the GMC. Surveys of 20 employees of the GMC applied. The feasibility to expand the GMC ward measured through Focus Group Interview by 12 internal and external experts. Data analysis methods derived from various surveys applied with data mining technique, frequency analysis, and Importance-Performance Analysis methods, and IBM SPSS statistical package program applied for data processing. Results: In the result of the big data analysis, the GMC's recognition on SNS is high. 95.9% of the residents and 100.0% of the employees required the need for the complex ward extension. In the analysis of expert opinion, in the future functions of GMC, specialized care (△3.3) and public medicine (△1.4) increased significantly. Conclusion: GMC's complex ward extension is an urgent and indispensable project to provide efficient hospital management and service quality.

Purpose: Various changes in nutrition, metabolism, immunity, and psychological status occur through multiple mechanisms after gastrectomy. The purpose of this study was to predict disease status after gastrectomy by analyzing diseases pattern that occur or change after gastrectomy. Materials and Methods: A retrospective cohort study was conducted using nationwide claims data. Patients with gastric cancer who underwent gastrectomy or endoscopic resection were included in the study. Eighteen target diseases were selected and categorized based on their underlying mechanism. The incidence of each target disease was compared by dividing the study sample into those who underwent gastrectomy (cases) and those who underwent endoscopic resection for early gastric cancer (controls). The cases were matched with controls using propensity score matching. Thereafter, Cox proportional hazard models were used to evaluate intergroup differences in disease incidence after gastrectomy. Results: A total of 97,634 patients who underwent gastrectomy (84,830) or endoscopic resection (12,804) were included. The incidence of cholecystitis (P<0.0001), pancreatitis (P=0.034), acute kidney injury (P=0.0083), anemia (P<0.0001), and inguinal hernia (P=0.0007) were higher after gastrectomy, while incidence of dyslipidemia (P<0.0001), vascular diseases (ischemic heart disease, stroke, and atherosclerosis; P<0.0001, P<0.0001, and P=0.0005), and Parkinson's disease (P=0.0093) were lower after gastrectomy. Conclusions: This study identifies diseases that may occur after gastrectomy in patients with gastric cancer.
