본 논문은 개방형 분산 시스템에서 여러 분산 응용 프로그래머들에게 보안 서비스 제공을 위한 설계모델에 대하여 분석한다. 범용 보안 서비스는 응용 프로그래머에게 공통적으로 사용할 수 있는 암호 알고리즘 및 인터페이스를 제공함으로써 프로그래머가 암호 알고리즘을 알지 못하여도 보안 서비스를 제공할 수 있다. 따라서, 본 논문에서는 다양한 응용 환경 또는 시스템 하부 구조에 독립적으로 사용될 수 있는 범용 암호 서비스 구조를 설계하기 위하여 PKI, GSS-API 및 GCS-API를 중심으로 각각 관련된 요구사항과 설계 모델을 분석한다.

본 연구는 출혈성 뇌졸중 환자의 배뇨장애 관련요인을 파악하기 위한 후향적 연구로서 환자의 나이와 출혈 부위는 배뇨장애와 관련성이 없었으며 출혈량이 많을수록, 입원기간이 길수록, 유치도뇨 기간이 길수록 GCS점수가 낮을수록 배뇨장애가 있는 것으로 나타났으나 배뇨장애에 영향을 미치는 요인으로는 유치도뇨 유지기간만이 유의하였으며, 유치도뇨 기간이 1일씩 늘어날 때마다 배뇨장애가 발생할 확률은 1.18배씩 늘어나는 것으로 나타났다.

An increasing number of observations have confirmed the presence of multiple stellar populations in Galactic globular clusters. Multiple populations evidence come from the complex chemical pattern of stars hosted in GCs and from the split or broadening of different evolutionary sequences in the color-magnitude diagrams. Multiple stellar populations have been identified in Galactic and Magellanic Cloud clusters, as well as in external galaxies. In this paper I will summarize the observational facts.

This paper presents the moving object detection and tracking algorithm using edge information base on human perceptual system The human visual system recognizes shapes and objects easily and rapidly. It's believed that perceptual organization plays on important role in human perception. It presents edge model(GCS) base on extracted feature by perceptual organization principal and extract edge information by definition of the edge model. Through such human perception system I have introduced the technique in which the computers would recognize the moving object from the edge information just like humans would recognize the moving object precisely.

무인항공기는 일반 유인항공기와는 다르게 크기의 제한이 없다. 또한 작은 사이즈의 무인항공기는 적은 인원의 투입으로도 항공기 각 분야의 검증이 가능하므로 소형화된 무인기는 여러 회사 및 연구원 학교등에서 개발되고 있다. 항공기의 크기가 작아지게 되면 운영요원의 숫자 또한 작아지게 되고 이로 인하여 쉽게 이동이 가능하고 운영이 가능한 이동형 무인항공기 지상통제 시스템의 요구가 생기게 된다. 본 논문에서는 한국항공주우연구원의 소형 무인기를 운영하기 위해 개발한 이동형 무인항공기 지상관제 시스템에 관하여 기술 하였다.

Purpose: The objective of this study was to develop a new scoring tool that is comprehensively applicable and predicts fatality within 24 h of intoxication. Methods: This was a cohort study conducted in two emergency medical centers from 2011 to 2012. We identified factors associated with severe/fatality. Through a discriminant analysis, we devised the aBIG (age, Base deficit, Infection, and Glasgow coma scale) score. To compare the ability of aBIG to predict intoxication severity with that of previous scoring systems such as APACHE II, MODS, SAPS IIe, and SOFA, we determined the receiver operating characteristic curves of each variable in predicting severe-to-fatal toxicity. Results: Compared with the mild/moderate toxicity group (n=211), the severe/fatal group (n=143) had higher incidences of metabolic acidosis, infection, serious mental change, QTc prolongation and hepato-renal failure. Age, base deficit, infection-WBC count, and Glasgow Coma Scale were independently associated with severe/fatal poisoning. These variables were combined into the poisoning "aBIG" score [$0.28{\times}$Age group+$0.38{\times}WBC$ count/$10^3+0.52{\times}$Base deficit+$0.64{\times}$(15-GCS)], which were each calculated to have an area under the curve of 0.904 (95% confidence interval: 0.868-0.933). The aBIG poisoning score had an equivalent level of severity predictability as APACHE II and a superior than MODS, SOFA, and SAPS IIe. Conclusion: We developed a simplified scoring system using the four variables of age, base deficit, infected leukocytosis, and GCS. The poisoning aBIG score was a simple method that could be performed rapidly on admission to evaluate severity of illness and predict fatal severity in patients with acute intoxications.

Purpose: The aim of this study was to evaluate the clinical characteristics of classic heat stroke in Korea and to identify factors of prognosis for heat stroke by comparing a survival group with a non-survival group. Methods: We retrospectively analyzed 27 patients with heat stroke who visited the Emergency Department of Kyungpook National University Hospital from March 2001 to February 2005. First, we divided the patients into two groups, the classic heat stroke group and the exertional heat stroke group, and compared them. Second, we compared the survival group with the non-survival group. Age, sex, cause, place where patients were found, underlying diseases, cooling time, performance of endotracheal intubation, initial Glasgow Coma Scale, initial vital sign, and laboratory findings were reviewed. Results: Five of 27 patients in heat stroke died. The classic heat stroke group had 20 patients. They were old and had more patients in the bathroom than the exertional heat stroke group had. The non-survival group showed lower blood pressure, lower initial GCS score, and higher respiratory rate than the survival group. In laboratory findings, the non-survival group also showed lower$HCO_3-$ level, lower albumin level, lower glucose level, more prolonged PT, and higher CK-MB level than the survival group. Delay in recognition of heat stroke and cooling were poor prognostic factors in heat stroke. Conclusion: The classic heat stroke group had patients who were old and found in the bathroom. Early recognition and treatment of heat stroke is important to reduce mortality. Cooling time, initial GCS score, mean arterial pressure, resipratory rate, $HCO_3-$, PT, CK-MB, and albumin seem to be meaningful when forming a prognosis for heat stroke patients.

Purpose: Carbapenemase-producing Enterobacteriaceae (CPE) are associated with considerable mortality. This study was aimed to identify survival factors among medical care unit patients with CPE. Methods: We conducted a retrospective cohort; data were collected from September 2017 to June 2019 through electronic medical records. The data collected were general characteristics, disease-related characteristics, severity-related characteristics, and treatment-related characteristics. Data were analyzed based on frequency, mean, standard deviation, Chi-square test, Fisher's exact test, t-test, Pearson's correlation coefficient, and Cox proportional hazard model using SPSS/WIN 21.0 program. Results: Seventy-seven patients were included (59 survivors and 18 deceased) in the study. Univariate analysis identified factors for survival associated with acquired CPE as age (t= -1.56, p= .037), simplified acute physiology 3 (SAPS3) score of admission date (t= -2.85, p= .006), Glasgow coma scale (GCS) of CPE acquisition date (t= 2.38, p= .020), artery catheter at CPE acquisition date (χ²= 4.58, p= .032), vasoconstrictor agents use at CPE acquisition date (χ²= 6.81, p= .009), platelet at CPE acquisition date (t= 2.27, p= .025), lymphocyte at CPE acquisition date (t= 2.01, p= .048), calcium at CPE acquisition date (t= 2.68, p= .009), albumin at CPE acquisition date (t= 2.29, p= .025), and creatinine at CPE acquisition date (t= 2.24, p= .028). Multivariate Cox proportional hazard model showed that GCS at CPE acquisition date (HR= 1.14, 95% CI= 1.05-1.22), lymphocyte at CPE acquisition date (HR= 1.05, 95% CI= 1.00-1.10), and creatinine at CPE acquisition date (HR= 1.25, 95% CI= 1.04-1.49) were independent survival factors among medical intensive care unit patients with CPE. Conclusion: Based on the study results, it is necessary to develop nursing interventions that can aid in the management of patients with CPE and identify their effects.
