The existing emergency medical systems are unable to obtain accurate clinical information, so most of the specialized first aid is being done within the hospital. In this paper, designed medical information transfer structure based on medical information standards HL7 for accurate first aid is proposed. The designed system can share clinical information and emergency medical information in terms of standard HL7 messages. Therefore, the correct first aid is available in steps taken by the hospital. In addition, the system of this paper has been implemented based on the OSGi service platform for the efficient integration with other health-related services.

The four taboos in using Baekhotang as explained by Odang(吳瑭), are identical to the standard symptoms of Severe Exterior Heat Syndrome[表熱重證]. There are similarities between Sanghan and Onbyeong in using Baekhotang(白虎湯). But there are significant differences between Sanghan and Onbyeong in explaining the pathogenesis of human body. In pattern identification by the Wi-Gi-Yoeng-Hyeol(衛氣營血) system, body fluid[津液] is the key feature, whereas in that of the Yuk-Gyeong(六經) system, Yanggi(陽氣) is the point. Therefore, we can understand that the standard symptoms of pattern identification are slightly different. However, that Sanghan and Onbyeong present different explanations does not mean that the disease itself strictly 'belong' to one category. They are different approaches, not explanations for two different subjects. Therefore, Sanghan and Onbyeong should be studied in line with this concept.

Purpose: Severe acute malnutrition (SAM) is an important public health problem which contributes to significant number of under five deaths. Protocol based management significantly decreases risk of deaths in children with medical complications. Methods: Outcome of children aged 2 months-5 years admitted and fulfilling definition of SAM having diarrhea (group A) was compared to children with SAM having medical complications other than diarrhea (group B). Both groups were managed according to standard recommended protocols and monitored and followed up for 12 weeks after discharge. Results: The average weight gain, defaulter rate, primary failure, secondary relapse rate and readmission rate were similar in both groups. Length of stay in group A was three days longer (p-value=0.039). Discharge rate was comparable with overall 68% of children successfully discharged and 50% of children reaching weight/height > -2 standard deviation at follow-up of 12 weeks. Conclusion: The current management protocol is equally effective for managing children with SAM having diarrhea. Good adherence to management protocol of dehydration and timely modification of therapeutic feeds in children with persistent diarrhea results in satisfactory weight gain.

Purpose: To analyze the proportion of medical institutions meeting the legal standard for nurse staffing. Methods: Data collected from 29,282 institutions between 1996 and 2013 were analyzed. Nurse staffing was measured as daily patient census per registered nurse (RN). The standard for general hospitals, hospitals, and clinics is 2.5 or less, and that for long-term care hospitals is 6.0 or less of the daily patient census per RN. Clinics may substitute nursing assistants for RNs by 50% or 100% depending on their daily inpatient census; long-term care hospitals may substitute nursing assistants for RNs by two thirds of the required number of RNs. Results: The proportion of general hospitals, hospitals, clinics, and long-term care hospitals meeting the standards was 63%, 19%, 63%, and 94%, respectively, in 2013. While general hospitals had an increase in the proportion during the 1996-2013 period, small changes were found in hospitals and clinics. In 2013, nurses were estimated to care for 16 (interquartile range: 12~24) patients per shift in general hospitals. Three quarters of clinics had no RNs in 2013. Conclusion: Many medical institutions did not meet the legally mandated minimum staffing level. The government must implement policy actions for all medical institutions to meet the legal standards.

Purpose: The purpose of this study was to compare the efficacy of two imaging modes in a cone beam computed tomography (CBCT) system in detecting root fracture in endodontically-treated teeth with fiber posts or screw posts by selecting two fields of view. Materials and Methods: In this study, 78 endodontically-treated single canal premolars were included. A post space was created in all of them. Then the teeth were randomly set in one of 6 artificial dental arches. In 39 of the 78 teeth set in the 6 dental arches, a root fracture was intentionally created. Next, a fiber post and a screw post were cemented into 26 teeth having equal the root fractures. High resolution (HiRes) and standard zoom images were provided by a CBCT device. Upon considering the reconstructed images, two observers in agreement with each other confirmed the presence or absence of root fracture. A McNemar test was used for comparing the results of the two modes. Results: The frequency of making a correct diagnosis using the HiRes zoom imaging mode was 71.8% and in standard zoom was 59%. The overall sensitivity and specificity in diagnosing root fracture in the HiRes mode were 71.79% and 46.15% and in the standard zoom modes were 58.97% and 33.33%, respectively. Conclusion: There were no significant differences between the diagnostic values of the two imaging modes used in the diagnosis of root fracture or in the presence of root canal restorations. In both modes, the most true-positive results were reported in the post space group.

Objectives: Bacterial resistant infections have become a global health challenge and threaten the society's health. Thus, an urgent need exists to find ways to combat resistant pathogens. One promising approach to overcoming bacterial resistance is the use of herbal products. Green tea catechins, the major green tea polyphenols, show antimicrobial activity against resistant pathogens. The present study aimed to investigate the effect of catechins, green tea extract, and methylxanthines in combination with gentamicin against standard and clinical isolates of Staphylococcus aureus (S. aureus) and the standard strain of Pseudomonas aeruginosa (P. aeruginosa). Methods: The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) values of different agents against bacterial strains were determined. The interactions of green tea extract, epigallate catechin, epigallocatechin gallate, two types of methylxanthine, caffeine, and theophylline with gentamicin were studied in vitro by using a checkerboard method and calculating the fraction inhibitory concentration index (FICI). Results: The MICs of gentamicin against bacterial strains were in the range of $0.312-320{\mu}g/mL$. The MIC values of both types of catechins were $62.5-250{\mu}g/mL$. Green tea extract showed insufficient antibacterial activity when used alone. Methylxanthines had no intrinsic inhibitory activity against any of the bacterial strains tested. When green tea extract and catechins were combined with gentamicin, the MIC values of gentamicin against the standard strains and a clinical isolate were reduced, and synergistic activities were observed (FICI < 1). A combination of caffeine with gentamicin did not alter the MIC values of gentamicin. Conclusion: The results of the present study revealed that green tea extract and catechins potentiated the antimicrobial action of gentamicin against some clinical isolates of S. aureus and standard P. aeruginosa strains. Therefore, combinations of gentamicin with these natural compounds might be a promising approach to combat microbial resistance.

Progress in medical science and cell biology has resulted in the transplantation of human cells and tissues from on human into another, facilitating reproduction and the restoration of form and function, as well as enhancing the quality of life. For more than 40 years, society has recognized the medical and humanitarian value of donation and transplanting organs and tissues. The standard operating procedures of hard tissues reflect the collective expertise and conscientious efforts of tissue bank professionals to provide a foundation for the guidance of tissue banking activities. Procurement of allograft tissues from surgical bone donors is a part of tissue banking. During the past decades the use of bone allografts has become widely accepted for the filling of skelectal defects in a variety of surgical procedures. In particular in the field of orthopaedic and oral and maxillofacial surgery the demand for allografts obtained from either living or post-mortem donors has increased. Hospital-based tissue banks mainly retrieve allografts from living donors undergoing primary total hip replacement for osteoarthritis or hemi arthroplasty for hip fractures and orthgnatic surgery such as angle reduction. Although bone banks have existed for many years, the elements of organized and maintaining a hospital bone bank have not been well documented. The experience with a tissue bank at Korea Tissue Bank(KTB) between 2001 and 2004 provides a model of procurement, storage, processing, sterilization and documentation associated with such a facility. The following report describes the standard operating procedures of hard tissues such as femoral head obtained from living donors.

The present study was undertaken to establish the decision standard of builds for the insured by using the ratio of weight-for-height as build index. Materials being examined were the ratio of weight-for-height being calculated from the actually measured heights and weights of a total of 15,838 insured persons who were examined medically at Honam Medical Department of Dong Bang Life Insurance Company, Ltd. from June, 1979 to September, 1985. The ratio of weight-for-height is calculated by the following formula. The ratio of weight-for-height(%)=$\frac{weight(kg){\times}100}{\{height(cm)-100\}{\times}0.9(kg)$ The results were as follows: 1. The distribution of the ratio of weight. for-height of the 15,838 insureds follows Log normal distribution being skewed to the left(the direction of underweight). 2. The ratio of weight-for-height were Log transformed to lead to a sym metrical pattern of distribution in which statistical rules are known to be applied more exactly. Thereafter, the establishment of dicision standard of builds was undertaken by using the log of the ratio of weight-for-height as build index. Through all ages in male, the ratio of weight-for-height indicating the range of standard lives including slight overweighted and underweighted lives besides normal lives is 80-130%, and corresponds to $"M-2{\delta}"-"M+1.5{\delta}"$ and to $M{\pm}20%$ ; in female, 85-135%, and corresponds to $"M-2{\delta}"-"M+1.5{\delta}"$ and to $M{\pm}20%$. Through all ages in male, the ratio of weight-for-height indicating the initial level of super-overweighted and super-underweighted lives is 130-150% and 75-80%,and corresponds to $M+3{\delta}\;and\;M-3{\delta}$ and to M+40% and M-25% respectively;in female, 140-160% and 75-80%, and corresponds to $M+3{\delta}\;and\;M-3{\delta}$ and to M+40%-+50% and M-25% respectively. 3. Author's rating table model for builds(a table of weight per height) is proposed. On the table, the ratings for builds, i. e. standard, super-weighted and super-underweighted lives, are listed.

Purpose: To investigate whether changes in Medical Aid (MA) status are associated with unmet need and catastrophic health expenditure (CHE). Methods: Data from the 2010 to 2014 Korea Health Panel (KHP) were used. The impact of changes in annual MA status ('MA to MA,' 'MA to MA Exit,' 'MA Exit to MA,' and 'MA Exit to MA Exit') on unmet need (all-cause and financial) and CHE (10% and 40% of household capacity to pay) were examined using the generalized estimating equation (GEE) model. Analysis was conducted separately for MA type I and II individuals. Results: In 1,164 Medical Aid type I individuals, compared to the 'MA to MA' group, the 'MA to MA Exit' group had increased likelihoods of all-cause and financial unmet need. This group also showed higher likelihoods of CHE at the 10% standard. The 'MA Exit to MA Exit' group showed increased likelihoods at the 10% and 40% CHE standards. In 852 type II recipients, the 'MA to MA Exit' group had higher likelihoods of CHE at the 10% standard. Conclusions: Type 1 MA exit beneficiaries had higher likelihoods of all-cause and financial unmet need, along CHE at the 10% standard. Type I 'MA Exit to MA Exit' beneficiaries also showed higher likelihoods of CHE at the 10% and 40% standards. In type II recipients, MA exit beneficiaries had higher likelihoods of CHE at the 10% standard. The results infer the importance of monitoring MA exit beneficiaries as they may be vulnerable to unmet need and CHE.

Objectives Despite the increasing use of Ja-ha-guh (Hominis-placenta ) pharmacopuncture in rehabilitative medicine field, its standard compound has yet to be investigated. The purpose of this study is to provide standardization for future studies and increase satisfaction of patients by utilizing standard pharmacopuncture. Methods Alanine and leucine were selected as potential standard compounds. LC/MS was used to devise an analytic method. This analytic method was subject to validation. According to validation guideline of Korea Food and Drug Administration, the specificity, linearity, precision, range, quantitative limits, detection limits and accuracy were measured. With this analysis, 3 lots of Ja-ha-guh pharmacopuncture were analyzed. Results Because the specificity, linearity, precision, range, quantitative limits, detection limits and accuracy meet criteria of the guideline, the analytic method was validated. It was found that Ja-ha-guh pharmacopuncture contained $211.02{\pm}7.28ug/ml$ of alanine and $372.03{\pm}7.58ug/ml$ of leucine. Conclusions Both alanine and leucine appear to be suitable standard compounds. These results are likely to contribute to further standardization of Ja-ha-guh for medical use.
