Purpose: Hypothermia at admission is associated with increased mortality and morbidity in preterm infants. We performed a quality improvement (QI) effort to determine the impact of a decrease in admission hypothermia in preterm infants. Methods: The study enrolled very low birth weight (VLBW) infants born at Gangnam Severance Hospital between January 2013 and December 2016. This multidisciplinary QI effort included the use of occlusive wraps, warm blankets, and caps; the delivery room temperature was maintained above $23.0^{\circ}C$, and a check-list was used for feedback. Results: Among 259 preterm infants, the incidence of hypothermia (defined as body temperature <$36.0^{\circ}C$) decreased significantly from 68% to 41%, and the mean body temperature on neonatal intensive care unit admission increased significantly from $35.5^{\circ}C$ to $36.0^{\circ}C$. In subgroup analysis of VLBW infants, admission hypothermia and neonatal outcomes were compared between the pre-QI (n=55) and post-QI groups (n=75). Body temperature on admission increased significantly from $35.4^{\circ}C$ to $35.9^{\circ}C$ and the number of infants with hypothermia decreased significantly from 71% to 45%. There were no cases of neonatal hyperthermia. The incidence of pulmonary hemorrhage was significantly decreased (P=0.017). Interaction analysis showed that birth weight and gestational age were not correlated with hypothermia following implementation of the protocol. Conclusion: Our study demonstrated a significant reduction in admission hypothermia following the introduction of a standardized protocol in our QI effort. This resulted in an effective reduction in the incidence of massive pulmonary hemorrhage.

The architecture in a differentiated services (DiffServ) network is based on a simple model that applies a per-class service in the core node of the network. However, because the network behavior is simple, the network structure and provisioning is complicated. If a service provider wants dynamic provisioning or a better bandwidth guarantee, the differentiated services network must use a signaling protocol with QoS parameters or an admission control method. Unfortunately, these methods increase the complexity. To overcome the problems with complexity, we investigated scalable dynamic provisioning for admission control in DiffServ networks. We propose a new scalable $qDPM^2$ mechanism based on a centralized bandwidth broker and distributed measurement-based admission control and movable boundary bandwidth management to support heterogeneous QoS requirements in DiffServ networks.

In various applications of queueing systems, admission control is often employed. It is known that the threshold-type of admission control is optimal in many practical applications despite its simplicity. However, determining the optimal threshold value is hard in general, because analytical expressions for the stationary queue length distributions are not easily available in most queueing systems. In this paper, to quickly determine the optimal threshold value under threshold-type admission control, we develop a concurrent simulation technique, which can save large amount of CPU time required in simulation, compared to the standard simulation procedure.

Purpose. The purpose of this study was to identify the clinical variables that predict functional and cognitive recovery at 1- and 6-month in both severe and moderate/mild traumatic brain injury patients. Methods. The subjects of this study were 82 traumatically brain-injured patients who were admitted to a Neurological Intensive Care Unit at a university hospital. Potential prognostic factors included were age, motor and pupillary response, systolic blood pressure, heart rate, and the presence of intracranial hematoma at admission. Results. The significant predictors of functional disability in severe traumatic brain injury subjects were, age, systolic blood pressure, the presence of intracranial hematoma, motor response, and heart rate at admission. In moderate/mild traumatic brain injury patients, motor response, abnormal pupil reflex, and heart rate at admission were identified as significant predictors of functional disability. On the other hand, the significant predictors of cognitive ability for severe traumatic brain injury patients were motor response and the presence of intracranial hematoma at admission, whereas those for moderate/mild patients were motor response, pupil reflex, systolic blood pressure at admission, and age. Conclusions. The results of the present study indicate that the significant predictors of TBI differ according to TBI severity on admission, outcome type, and outcome measurement time. This can be meaningful to critical care nurses for a better understanding on the prediction of brain injury patients. On the other hand, the model used in the present study appeared to produce relatively low explicabilities for functional and cognitive recovery although a direct comparison of our results with those of others is difficult due to differences in outcome definition and validation methods. This implies that other clinical variables should be added to the model used in the present study to increase its predicting power for determining functional and cognitive outcomes.

Purpose: This study aimed to develop nursing practice standards of hemodialysis care according to admission types. Methods: The standards were developed in four phases. Phase 1: The preliminary standards of hemodialysis care were developed based on literature review and evaluation of professional experts. Phase 2: Content validity was evaluated by 34 professional experts and the standards were modified and revised. Phase 3: Clinical validity was evaluated by 212 hemodialysis nurses. Expert group validated and verified the final outcome. Phase 4: Final standards of hemodialysis care according to admission types were developed. Results: The standard of hemodialysis care for out-patients included 5 standards, 9 contents, 43 nursing activities. The standard for in-patients included 6 standards, 10 contents, 50 nursing activities. The standards for critical patients included 4 standards, 10 contents, 43 nursing activities. There were differences in nursing activities according to admission type. Time required to meet the standards were different according to admission types. Conclusion: The findings of this research demonstrated that the time required for hemodialysis care and appropriate number of nurse would be different according to admission types. Different nursing workload according to admission type of hemodialysis patients need to be considered in allocating nursing manpower.

최근 입학사정관제에 대한 여러 가지 논의가 대두되고 있으나, 입학사정관제로 뽑힌 학생들의 대학 입학 후 학업성과에 대한 연구는 거의 이루어지지 않고 있다. 본 논문은 이 주제에 대해 서울 시내 한 대학의 협조로 그 대학의 2009년 입학생 데이터를 이용해 입학사정관 입학생과 일반전형 입학생 간의 입학당시 성적과 입학후 1년간의 학업성과에 대해 분석하였다. 해당 데이터를 분석한 결과 두 가지 주안점이 밝혀졌다. 입학당시 입학사정관 전형 입학생은 일반전형 입학생에 비해 뚜렷하게 떨어지는 학업성과를 보였다. 그러나 입학후 1년간의 평균학점 분석에서 두 전형 입학생 사이에 통계적으로 유의한 학점 차이는 나타나지 않았다. 이 결과는 입학사정관제가 잠재력 있는 학생을 선발하는 효과적인 방법 중 하나라는 사실을 보여준다.
