Purpose: This study was aimed to specify roles of nurses from the anesthesia and recovery room by analyzing nursing activities as well as anesthesia nursing during surgery. Method: The objects were 12 RNs working in the recovery room of a university hospital located in Incheon. Self-report was performed by measuring stop-watch for five days from May 17th to May 21st in 2004. Research method was designed to record the time and frequency of the nursing activity from anesthesia and recovery room based on nurses' statement and other references for five days. The data were analyzed with descriptive statistics, ANOVA, and t-test via SPSS Win 10.0 program. Result: Nursing activities in anesthesia recovery room were classified into two different characteristics such as direct and indirect nursing activity. The activities consisted of 11 direct nursing areas and 39 nursing activities in anesthesia preparation room. The indirect nursing was classified into 8 nursing areas and 32 nursing activities. The direct nursing was classified into 12 nursing areas and 55 nursing activity. Also, the indirect nursing was classified into 7 nursing areas and 21 nursing activities in recovery room. In terms of prevalence of nursing activities in the anesthesia preparation room, observation and cooperation of anesthesia was the most prevalent activity, drug and eqipment management the second prevalent, and drug administration the third. On the other hand, in the recovery room, the most prevalent activity was vital sign checking and observation, the second most prevalent activity informative activity, and the third body temperature control. Nursing activity time was recorded according to the nursing characteristics. In the anesthesia preparation room, the direct nursing spent for 8092.20 minutes was larger than the indirect nursing spent for 7198.50 minutes. Also, in the recovery room, the direct nursing spent for 2361.16 minutes was larger than the indirect nursing spent for 1134.13 minutes. 4. Nursing activity time was compared to duty shifts. In the anesthesia preparation room, the direct nursing was more prevalent on day shift and the indirect nursing was prevalent on evening shift. However, in the recovery room, both direct and indirect nursing activities were prevalent on day shift. Conclusion: The role of anesthesia and recovery room nurses was analysed according to the time, frequency, and its characteristics.

Cough is a common clinical problem to which various etiologies are attributable. In Korean medicine there are differentiations in etiology such as food-accumulation and Yin-deficiency. This study was aimed to analyze the relations between the time of cough and Korean syndrome differentiations and to compare the symptoms of Korean syndrome differentiations (food-accumulation and Yin-deficiency). Sixty-two cough patients were analyzed and classified into one of two syndrome differentiations by etiology. We compared the time of coughing and symptomatic characteristics of two: such as symptom differences and change of severity after treatment. Patients with food-accumulation were more prevalent than patients with Yin-deficiency. Among symptoms, anorexia, dyspepsia, nausea and nasal discharge were more prevalent in food-accumulation while pruritus of throat was prevalent in Yin-deficiency. Coughing at night was prevalent in Yin-deficiency and coughing at rising hour was prevalent in food-accumulation.

Flexible circular cantilever beams when excited externally introduce a lot of dynamic characteristics. The non-linear elements that these flexible beams develop include non-linearity due to inertia terms, spring, and damping. They show different characteristics of motion from each other. In the modes of lower order, the non-linearity due to spring is prevalent, while the non-linearity due to inertia Is prevalent in the modes of higher order. To analyze these effects the non-linear phenomena are analyzed experimentally. When the response characteristics of non-linear vibration are analyzed using autospectrum, it is possible to analyze the subharmonic and superharmonic mot ion by comparison. The phase change is analyzed using the method of phase portrait and the non-linear characteristics of response characteristics that are developed in flexible structures can be predicted and applied to the stage of design.

The purposes of this study were to examine the consumer beliefs on the wrongness and occurrence of unethical behaviors in retail settings, to examine the differences in unethical beliefs by consumer characteristics, and to examine the effects of anomie on unethical beliefs. A total of 609 questionnaires collected from a consumer survey were analyzed. Results revealed that respondents tended to perceive illegal activities as the most unethical and the least prevalent behaviors and downloading intellectual properties as the least unethical and the most prevalent behaviors. There were differences by age, marital status, occupation, and education in the four dimensions of unethical beliefs including actively benefiting from illegal/deceiving activities, passively benefiting at the expense of the seller, no harm/no foul, and common but questionable actions. Partial differences were observed by shopping frequency and return experience. Valuelessness of anomie affected actively benefiting from illegal/deceiving activities and no harm/no foul.

본 논문에서는 경로감쇠에 기반한 실내 음향측위 시스템에 활용할 수 있는 실내 음향신호의 경로 감쇠 특성을 분석한다. 실내 음향시스템은 주로 25 평방미터 이내의 협소한 공간에서 적용되기 때문에 기존에 정의된 넓은 공간에서의 모형만으로는 경로감쇠에 기반한 실내음향측위 시스템을 설계할 수 없다. 따라서 본 논문에서는 자유음장 모형과 더불어 실내공간의 온도와 습도, 그리고 대기의 주요구성성분의 홉음영향을 고려한 실내 음향신호 경로 감쇠 모형을 보이고, 무향실에서 실제 실험을 통해 모형의 적절성을 평가한다. 실험을 위해서 1kHz-20kHz의 단일 주파수를 갖는 감쇠정현파를 사용한다. 그리고 실험 음원으로 두개 이상의 단일 주파수를 갖는 감쇠정현파를 함게 사용할 대의 경로감쇠를 보이고, 이를 분석한다.

Purpose: Escherichia coli sequence type (ST) 131, a multidrug-resistant clone causing extraintestinal infections, has rapidly become prevalent worldwide. However, the epidemiological and clinical features of pediatric infections are poorly understood. We aimed to explore the characteristics of ST131 Escherichia coli isolated from Korean children with urinary tract infections. Methods: We examined 114 uropathogenic E. coli (UPEC) isolates from children hospitalized at Chung-Ang University Hospital between 2011 and 2014. Bacterial strains were classified into STs by partial sequencing of seven housekeeping genes (adk, fumC, gyrB, icd, mdh, purA, and recA). Clinical characteristics and antimicrobial susceptibility were compared between ST131 and non-ST131 UPEC isolates. Results: Sixteen UPEC isolates (14.0%) were extended-spectrum ${\beta}-lactamase$ (ESBL)-producers; 50.0% of ESBL-producers were ST131 isolates. Of all the isolates tested, 13.2% (15 of 114) were classified as ST131. There were no statistically significant associations between ST131 and age, sex, or clinical characteristics, including fever, white blood cell counts in urine and serum, C-reactive protein, radiologic abnormalities, and clinical outcome. However, ST131 isolates showed significantly lower rates of susceptibility to cefazolin (26.7%), cefotaxime (40.0%), cefepime (40.0%), and ciprofloxacin (53.3%) than non-ST131 isolates (65.7%, 91.9%, 92.9%, and 87.9%, respectively; P<0.001 for all). ESBL was more frequently produced in ST131 (53.3%) than in non-ST131 (8.1%) isolates (P<0.01). Conclusion: ST131 E. coli isolates were prevalent uropathogens in children at a single medical center in Korea between 2011 and 2014. Although ST131 isolates showed higher rates of antimicrobial resistance, clinical presentation and outcomes of patients were similar to those of patients infected with non-ST131 isolates.

Objectives: Dehospitalization of long-term inpatients with schizophrenia can be difficult because of complex factors such as chronic symptoms and low family and social support. The aim of this study was to identify factors related to dehospitalization and readmission of long-term inpatients with schizophrenia. Methods: This retrospective study reviewed the medical records of patients discharged from a psychiatric hospital in Yongin, South Korea, from February 1, 2016, to July 31, 2017. Patients who were hospitalized for over 3 months were divided into two groups: readmission (n=47) and dehospitalization (n=55). Differences in sociodemographic and clinical factors were analyzed between the two groups. Results: Regarding sociodemographic characteristics, female sex, familylessness, discharge to nursing homes, and discharge after symptom improvement were more prevalent in the dehospitalization group, whereas male sex, having a sibling as next of kin, and discharge because of other problems were more prevalent in the readmission group. Among clinical characteristics, hospital stay was longer in the readmission group. Conclusion: In this study, patients without a family showed a tendency to not be readmitted when they were discharged to nursing homes after symptom improvement. Expansion of social welfare support may encourage dehospitalization of long-term inpatients with schizophrenia.
