Background: The purpose of this study was to identify role ambiguity of comprehensive nursing care unit nurses. Methods: A concept analysis method by Walker and Avant was used to understand role ambiguity of comprehensive nursing care unit nurses. Results: The antecedents of role ambiguity of nurses at comprehensive nursing units were shortage of nurses, unclear admission criteria, and demands for customized nursing care according to severity. Attributes include ambiguity in role delegation, patient placement ambiguity, and professional ambiguity among nursing staff. The consequences were diminished job satisfaction due to excessive workload, difficulty in resolving role ambiguity due to the lack of work analysis studies, and poor outcome of nursing indicators. Conclusion: Improvement of nationwide awareness for comprehensive nursing care unit is required. Clear division at scope of practice for nursing staff in accordance of each medical institution's characteristics is essential. Nurses at comprehensive nursing care unit should understand nature of role ambiguity that occurs as they work in large groups. Nurses should promote communications between nursing staff and they must have volition to improve status quo. An additional research of comprehensive nursing care on the causes of role ambiguity in the practice of nursing care for ward nurses is needed, and management measures should be sought at the organizational level.

Objective : The aim of this study is to investigate rota virus infection of neonates In the Postpartum care center. Methods : This clinical study was carried out with the 205 neonates who admitted to the Postpartum Care Center of ${\bigcirc}{\bigcirc}$ Oriental Medicine Hospital, from July, 2004 to July, 2005. Stools were examined daily with Rotazyme ELISA tests(Bio Line Rota Virus, SD Standard Diagnostics, INC.) for 3 days from the day of admission. Supplementary test was examined when change was found in stools. Results : Among 205 newborn babies, 58 cases turned out to be positive. The positive rate of rota virus was not significantly related to sex, birth weight, gestation age. But, it was significantly related to delivery method and it was higher in caesarean section group. The manifestation rates of symptoms were 51.7% in Rotazyme positive neonates. In the Rotazyme positive 58 cases, 30 cases(51.7%) had diarrhea, 8 cases had fever(13.8%), 1 case(1.7%) had vomiting. The positive rate of rota virus was higher during from october to march. There were 190 cases(92.2%) of mixed feeding and 15 cases(7.8%) of artificial feeding. There was significance between breast feeding and the positive rate of rota virus. There was no significance between hospital of birth and the rate of positive rotazyme test. Conclusions : A further study of neonates in postpartum care center is necessary as preference of postpartum care center was increased. And the oriental medicine treatment of rota virus IS expected to be effective, so a further study is necessary.

Background: Predicting the prognosis of patients admitted to the pediatric intensive care unit (PICU) is very important in determining further management and resource allocation. The prognostication of critically ill children can be challenging; hence, accurate methods for predicting outcomes are needed. Purpose: To evaluate the role of microalbuminuria at admission as a prognostic marker in comparison to standard Pediatric Risk of Mortality (PRISM) and Pediatric Logistic Organ Dysfunction (PELOD) mortality scores in children admitted to the PICU. Methods: This cross-sectional study was conducted from January 2015 to October 2016. Eighty-four patients aged 1 month to 18 years admitted to the PICU of teaching hospitals for more than 24 hours were enrolled by convenience sampling method. Microalbuminuria was estimated by spot urinary albumin-creatinine ratio. PRISM and PELOD scores were calculated using an online calculator. Outcome measures were PICU length of stay, inotrope usage, multiorgan dysfunction, and survival. ACR was compared with mortality scores for predicting survival. Results: Microalbuminuria was present in 79.8% with a median value of 85 mg/g (interquartile range, 41.5-254 mg/g). A positive correlation was found between albumin-creatinine ratio and PICU length of stay (P=0.013, r=0.271). Albumin-creatinine ratio was significantly associated with organ dysfunction (P=0.004) and need for inotropes (P=0.006). Eight deaths were observed in the PICU. The area under the curve for mortality for albumin-creatinine ratio (0.822) was comparable to that for PRISM (0.928) and PELOD (0.877). Albumin-creatinine ratio >109 mg/g predicted mortality with a sensitivity of 87.5% and specificity of 63.2%. Conclusion: Microalbuminuria is a good predictor of PICU outcomes comparable with mortality scores.

대표적 가중치 기반 공정 패킷 스케줄링 방식인 WFQ(weighted Fair Queuing)는 자원의 공정한 배분과 더불어 개별 트래픽 흐름이 요구하는 품질을 보장할 수 있어 RSVP(resource reservation protocol) 라우터에 널리 이용되어 왔다. RSVP는 패킷의 손실 없이 트래픽 흐름의 요구속도와 종단간 지연한계를 보장할 수 있는 자원을 예약하고, WFQ 스케줄러는 예약된 자원을 이용하여 흐름의 품질보장을 실현한다. 그러나 품질 보장형 서비스라 하더라도 실제적으로 몇 %까지의 패킷 손실이 허용된다. 따라서 패킷 손실을 허용하도록 RSVP와 WFQ를 개선할 필요가 있다. 본 연구에서는 패킷 손실을 허용하는 WFQ 방식에 대해 연구하고, 그의 성능을 평가한다. 성능평가 결과 0.4%의 패킷 손실을 허용할 경우 40% 정도의 흐름 수용 능력이 개선되는 효과를 관찰하였다.

Purpose : The purpose of this study was to systematically review the instruments utilized to assess physical impairment in post-intensive care syndrome (PICS) of intensive care unit (ICU) survivors. Method : Online databases searched were MEDLINE, Cochrane, CINAHL, and Embase. Studies that met the following criteria were included: 1) the study population exclusively had experience with ICU admission; 2) the study assessed pulmonary, neuromuscular, and physical functions; and 3) the study was published in English language journals after 2007. Results : A total of 56 instruments (2 pulmonary, 25 neuromuscular, 29 physical function) from 94 studies were reviewed. They were classified into self-report, observation, and measurement according to the type of assessment. No instrument measured all 3 areas of physical impairment. Five instruments were originally developed for the ICU patients. The most frequently applied instruments were the Medical Research Council and the 36-item Short Form Survey (physical component summary), which were used in 23 studies each. Only 13.8% of reviewed studies reported the reliability or validity of the instruments. Conclusion : Our results suggest that the appropriateness of instruments assessing physical impairment in PICS cannot be guaranteed. Despite the multidimensional concept of physical disabilities, most studies measured only one area, and studies that reported psychometric properties were limited. Accordingly, we propose to develop a unique and multifaceted instrument for ICU survivors.

Background: Pediatric deep neck infection can cause critical complications in that they are seldom able to verbalize symptoms or cooperate with physical examination. The objective of this study is to identify the clinical characteristics according to age. Material and Method: A retrospective study was performed on 26 cases with pediatric deep neck infection during 12 years. Patients were classified infancy group (1-7 yr, 19.2%), preschool age group (7-15 yr, 30.8%) and school age group (15 yr-, 50%). We analyzed the age, sex, sites of abscess, predisposing factors, symptoms and compared onset, hospital date, laboratory and outcomes at each group. Results: In pediatric patients with deep neck infection, the age distribution was 18 males (69.2%) and 8 females (30.8%), the mean age was 7.4 years. The most common infection site was the anterior cervical triangle and submandibular space (19.2%). The most commonly known associated preceding disease was upper viral infection (34.6%), but we could not find the preceding diseases in most of cases (50%). Neck swelling (69.2%) was the most frequent symptom. The mean age of patients who performed neck CT was 8.23 years and neck US was 2.75 years. The younger patients were preferred to perform the neck US than the neck CT (p=0.022). The mean time from disease onset to admission was 9 days in the infancy, 5.5 days in the preschool aged and 5 days in the school aged group. The surgical treatment was performed in 30.8% of school aged, 62.5% of preschool aged and 100% of infancy group. Surgical treatment was preferred to younger patients (p=0.026). Conclusion: Abscess sites, size, and antibiotics susceptibility and especially patient age should be carefully considered in treating pediatric deep neck infection.
