Background: Recently, Cervi Parvum Cornu pharmacopuncture has been widely used. But no studies on the indicator materials for Cervi Parvum Cornu pharmacopuncture have been conducted. The aim of this study was to select indicator materials that would aid in the uniform preparation of standardized Cervi Parvum Cornu pharmacopuncture. Methods: Three lots of Cervi Parvum Cornu pharmacopuncture were analysed. Each lot was prepared using the same methods and materials. Chondroitin sulfate, alanine, and leucine were selected as the indicator materials for Cervi Parvum Cornu. For standardization, chondroitin sulfate analysis was performed using the colorimetric method, while alanine and leucine were analyzed using liquid chromatography-mass spectrometry (LC-MS). Results: Analysis of the three lots of Cervi Parvum Cornu pharmacopuncture found chondroitin sulfate levels of $108.9{\pm}17.3ug/ml$, $118.8{\pm}5.0ug/ml$ and $112.3{\pm}11.9ug/ml$. Alanine levels were $44.9{\pm}2.8ug/ml$, $44.6{\pm}0.3ug/ml$, and $43.9{\pm}0.2ug/ml$. Leucine levels were $29.6{\pm}0.7ug/ml$, $29.0{\pm}0.1ug/ml$, and $29.4{\pm}0.1ug/ml$. Conclusion: These results suggest that chondroitin sulfate, alanine, and leucine may be useful for the standardization of Cervi Parvum Cornu pharmacopuncture.

Objectives: Although chuna medicine has progressed distinguishingly, yet chuna medical terminology hasn't been standardized. So there are a lot of difficulties in translating chuna related book and their meaning cannot be conveyed properly. For this reason, we could say standardization of chuna medical terminology is very essential. Purpose of our study was to develope a standard database of concept terms for chuna medicine, in addition, we considered establishing fundamental principles of chuna medical terminology. Methods: To select standard chuna medical terms, we sorted important chuna medical index words. Then we sorted those words into a group that has same meanings and united to one single term. In the meantime, we extracted index words from 26 domestic and foreign manual technique related books and sorted them out and based on these word, we translated chuna medical terms to Korean terms. In the case of chuna technique terms, we searched chuna text books for term those were wrongly used, and corrected them by suggesting fundamental principles of terminology. Results: 664 chuna words were selected as standard chuna terms and have been translated to English terms. In the process, adscititious words such as anatomical terms and title of books were exempted and selected only important words that could be used as index of chuna terms. In deciding essential elements of chuna technique terms, patient position, contact point, segmental contact point, malposition, procedure method were selected. Conclusions: Correcting chuna medical terms in a sort period could cause confusion, but in long term perspective, in the aspect of conveying the meaning clearly and education purpose, standardizing of chuna medical terminology must be done. From this study, standardization of chuna medical terms were chosen in large category, but further studies must be followed in order to standardize terms of subdivisional categories.

Purpose: Previous studies suggest that the concentration of 25-hydroxyvitamin D [25(OH)D] in cord blood may show an inverse association with respiratory tract infections (RTI) during childhood. The aim of the present study was to examine the influence of 25(OH)D concentrations in cord blood on infant RTI in a Korean birth cohort. Methods: The levels of 25(OH)D in cord blood obtained from 525 Korean newborns in the prospective COhort for Childhood Origin of Asthma and allergic diseases were examined. The primary outcome variable of interest was the prevalence of RTI at 6-month follow-up, as diagnosed by pediatricians and pediatric allergy and pulmonology specialists. RTI included acute nasopharyngitis, rhinosinusitis, otitis media, croup, tracheobronchitis, bronchiolitis, and pneumonia. Results: The median concentration of 25(OH)D in cord blood was 32.0 nmol/L (interquartile range, 21.4 to 53.2). One hundred and eighty neonates (34.3%) showed 25(OH)D concentrations less than 25.0 nmol/L, 292 (55.6%) showed 25(OH)D concentrations of 25.0-74.9 nmol/L, and 53 (10.1%) showed concentrations of ${\geq}75.0$ nmol/L. Adjusting for the season of birth, multivitamin intake during pregnancy, and exposure to passive smoking during pregnancy, 25(OH)D concentrations showed an inverse association with the risk of acquiring acute nasopharyngitis by 6 months of age (P for trend=0.0004). Conclusion: The results show that 89.9% of healthy newborns in Korea are born with vitamin D insufficiency or deficiency (55.6% and 34.3%, respectively). Cord blood vitamin D insufficiency or deficiency in healthy neonates is associated with an increased risk of acute nasopharyngitis by 6 months of age. More time spent outdoors and more intensified vitamin D supplementation for pregnant women may be needed to prevent the onset of acute nasopharyngitis in infants.

Objective: We aimed to investigate whether image standardization using deep learning-based computed tomography (CT) image conversion would improve the performance of deep learning-based automated hepatic segmentation across various reconstruction methods. Materials and Methods: We collected contrast-enhanced dual-energy CT of the abdomen that was obtained using various reconstruction methods, including filtered back projection, iterative reconstruction, optimum contrast, and monoenergetic images with 40, 60, and 80 keV. A deep learning based image conversion algorithm was developed to standardize the CT images using 142 CT examinations (128 for training and 14 for tuning). A separate set of 43 CT examinations from 42 patients (mean age, 10.1 years) was used as the test data. A commercial software program (MEDIP PRO v2.0.0.0, MEDICALIP Co. Ltd.) based on 2D U-NET was used to create liver segmentation masks with liver volume. The original 80 keV images were used as the ground truth. We used the paired t-test to compare the segmentation performance in the Dice similarity coefficient (DSC) and difference ratio of the liver volume relative to the ground truth volume before and after image standardization. The concordance correlation coefficient (CCC) was used to assess the agreement between the segmented liver volume and ground-truth volume. Results: The original CT images showed variable and poor segmentation performances. The standardized images achieved significantly higher DSCs for liver segmentation than the original images (DSC [original, 5.40%-91.27%] vs. [standardized, 93.16%-96.74%], all P < 0.001). The difference ratio of liver volume also decreased significantly after image conversion (original, 9.84%-91.37% vs. standardized, 1.99%-4.41%). In all protocols, CCCs improved after image conversion (original, -0.006-0.964 vs. standardized, 0.990-0.998). Conclusion: Deep learning-based CT image standardization can improve the performance of automated hepatic segmentation using CT images reconstructed using various methods. Deep learning-based CT image conversion may have the potential to improve the generalizability of the segmentation network.

This study purported to acquire information necessary to improve the operational efficiency of general hospitals. It tried to determine major indices which represent managerial performance of general hospitals and to identify the managerial characteristics of general hospital which affect the major financial indices. 201 hospitals which were subject to standardization audit by the Korean Hospital Association were investigated and 80 hospitals were finally chosen for this study. Their financial and managerial data during the period between January 1991 and December 1991 were collected. Considering financial indices in this study were the ration of net income to total asset, income growth rate, and quick ration. The results of study are summarized as followings. First. The ration of net income to total assets and quick ration were highly related to managerial characteristics of general hospitals. Therefore, the standardization of three financial indices should be needed to systematically check the operational efficiency of general hospitals. Second, the sample hospitals can be classified as four groups on the basis of their financial indices' level. 4 of those hospitals(5.0%) showed high level of performance in terms of three financial indices and 27 of them(33.7%) showed that they are highly related to only two financial indices. 34 hospitals(42.5%) showed they have high level of relationship with only one indices and 15 hospitals(18.8%) showed very weak performance level with three indices. In addition, there is no hospitals to show mid-range level of managerial performance in relation to all three financial indices. Third, there is no significant relationship between three financial indices and the managerial characteristics of hospitals such as the number of beds, type of operation, location of hospitals, and etc. However, in the case of hospitals which have high level of managerial performance, they have more specialists and medical support personnel in comparison to low performance hospitals. They also have high level of bed occupancy rate and average length of stay(ALOS). In conclusion, the study showed the standardization of 3 financial indices are necessary to systematically evaluate the managerial performance of general hospitals and provide more accurate operational information for each hospital. To do so, it is necessary to focus on management side of hospital such as the effective human resource management and quality enhancement of medical treatment.

컴퓨터에 전자적 형태로 저장된 의무기록인 EMR의 표준화에 대한 논의가 활발하다. 이는 EMR 표준화를 통해 의료 서비스의 향상을 기대할 수 있을 뿐만 아니라, 의료와 IT의 융합영역인 의료 빅데이터의 가치가 점차 높아지고 있기 때문이다. EMR 표준화와 관련한 주요 이슈 중 하나는 EMR 표준화의 필요성과 효과성을 이해관계자들에게 설득시키는 일이다. 연구자는 EMR 표준화에 대한 의사들의 인식을 기술 관점과 경제적 관점에서 살펴보고자 설문조사를 실시한 후 이에 대해 통계분석을 실시하였다. 실증분석 결과, EMR 시스템의 기능 품질과 경제적 가치는 EMR 표준화에 대한 유용성 인식과 수용 의도에 정(+)의 영향을 미치는 반면, 상호운용성은 유용성 인식에만 영향을 미치는 것으로 나타났다. 또한, 경제적 가치가 EMR 표준화 필요성에 대한 공감대 형성에 가장 중요한 변수로 확인되었다.
