To efficiently reduce on-grid energy consumption, the admission control algorithm in the hybrid energy powered cellular network (HybE-Net) with base stations (BSs) powered by on-grid energy and solar energy is studied. In HybE-Net, the fluctuation of solar energy harvesting and energy consumption may result in the imbalance of solar energy utilization among BSs, i.e., some BSs may be surplus in solar energy, while others may maintain operation with on-grid energy supply. Obviously, it makes solar energy not completely useable, and on-grid energy cannot be reduced at capacity. Thus, how to control user admission to improve solar energy utilization and to reduce on-grid energy consumption is a great challenge. Motivated by this, we first model the energy flow behavior by using stochastic queue model, and dynamic energy characteristics are analyzed mathematically. Then, fuzzy logic based admission control algorithm is proposed, which comprehensively considers admission judgment parameters, e.g., transmission rate, bandwidth, energy state of BSs. Moreover, the index of solar energy utilization balancing is proposed to improve the balance of energy utilization among different BSs in the proposed algorithm. Finally, simulation results demonstrate that the proposed algorithm performs excellently in improving solar energy utilization and reducing on-grid energy consumption of the HybE-Net.

Recently there have been many arguments about the admission officers system, but the majority of researches about admission officer has not focused student performance. We compared learning performances of students selected by admission officers and students selected by standardized test. We checked the marks of students at college entrance point and the average grade for their freshman year. Analyzing the data, we got two major findings. At the point of entrance, the students selected by admission officers had less performances. But the analysis of average grade for 1 year, there were no statistical differences between two groups of students.

This study was conducted for 39 patients who are recipients of allogeneic hemopoietic stem cell transplantation at BMT ward of St. Mary's hospital affiliated to Catholic University of Korea from April to September 1999. The subjects were devided into two groups; those who received both TEl and chemo therapy as conditioning regimen (TEl group). and those who used chemo agents as singular conditioning regimen (chemo group). The oral intake status of the two groups were compared through physical assessment and blood chemistry exam of the subjects, and factors influencing their nutritional change and oral intake were explored in each stage of the transplantation (six stages: admission, conditional stage, date of transplantation, one week after transplantation, two weeks after transplantation, and three weeks after transplantation). The prior aim of the study was to provide baseline data to minimize delayed treatment from nutritional deficiency of the subjects. The results were as follows: 1. TBI group was significantly decreased of oral calorie intake in two weeks after transplantation compared to admission and conditioning stage while that of chemo group was significantly decreased on the date of transplantation. 2. TBI group was significantly decreased of protein intake in two weeks after transplantation compared to admission and conditioning stage. In chemo group, protein intake was significantly decreased on the date of transplantation compared to admission. It was remarkable that TBI group showed lesser protein intake than chemo group. 3. Both group were significantly decreased of BMI in one week and three weeks after transplantation compared to admission. TBI group showed significantly higher BMI than chemo group. 4. Both group were significantly decreased of Triceps Skinfold Thickness (TST)on the date of transplantation compared to admission stage. 5. TBI group was significantly decreased of mid-arm muscle circumference (MAMC) in two weeks after transplantation compared to admission, conditioning, date of transplantation. 6. TBI group was significantly decreased of albumin level in two weeks after transplantation compared admission stage. In chemo group, it was significantly decreased on the date of transplantation compared to admission, three weeks after the transplantation. 7. TBI group was significantly decreased of transferrin level in two weeks after transplantation compared admission, conditioning, date of transplantation and one week after transplantation. In chemo group, it was decreased of transferrin level in 3 weeks after transplantation. 8. Oral intake of TEl group was impacted by vomiting before transplantation and gingivitis after transplantation. In chemo group, it was impacted by vomiting before transplantation and by two factors, gingivitis and nausea, after transplantation. The results showed oral calorie intake was not different between the two groups while protein intake was significantly lower in TBI group than chemo group. Oral intake was significantly impacted by vomiting before transplantation in both groups, but affected by oral gingivitis in TBI group and gingivitis and nausea in chemo group after transplantation. This findings present that standardized strategies to manage nutrition and gingivitis more effectively are desperately needed to enhance oral intake and protein intake of patients who receive TBI as conditioning regimen.

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: To investigate the levels of uncertainty and anxiety at admission and discharge to the isolation unit for patients undergoing hematopoietic stem cell transplantation (HSCT). Method: The data were collected from 60 patients who were admitted to the department of HSCT. Uncertainty and anxiety were assessed using the Mishel Uncertainty in Illness Scale (MUIS) and Anxiety Inventory (STAI). Collected data were analyzed using the SAS program. Results: The mean score for anxiety at admission was 2.20, and at discharge 2.10. The mean score for uncertainty at admission was 2.19, and at discharge 2.07. The anxiety at admission the group with physical discomfort was higher than that of group without physical discomfort. A positive relationship was found between anxiety and uncertainty at admission and at discharge. The major variables were expectation for cure and physical discomfort, explaining 25.87% of the anxiety at admission. The major variable was expectation for cure, explaining 20.94% of the uncertainty at admission. Conclusion: Front the above results, it can be concluded that support and consideration are required to reduce anxiety of the inpatient in single room.

In a Video-on-Demand system, admission control that is used to serve multimedia data efficiently has to be perfonned by an accurate grasp of the condition of surplus resources. Most of all. we need to adaptable admission control mechanism because the disk has irregular response time caused by external elements of disk, and also has high deviation of amount demanded. In previous admission control schemes, they determined whether a new user is granted or not through a theoretical value. Although they based on the measurement, they left much to be desired in dealing with the service state. Measurement ~based statistical admission control scheme, as we su~~ested in this research, perfonns 2 processes of off-line process and on-line process in real service environment. Through this processes, we can grasp the accurate resource state of system and adaptive!y detennine the admission according to circumstances. Therefore, it can guarantee both maximum resource utilization and QoS(Quality of Service). On performance evaluations, we show that the video server can utilize maximum resource utilization with QoS guarantee through precision of perfonnance by measurement and adaptable admission control according to the requested bandwidth.

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.

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.
