Pain is commonly characterized as a multi-dimensional experience, varing in quality as well as in intensity. So, We need to understand the lived experience of primiparous women in order to provide basic information of nursing care. Therefore, The purpose of the study is to explore the construction of labor pain experience. The data are collected through in-depth interviews of 20 primiparous women in Pusan city from March 1998 to May 1998. Their labor pain experiences conducted 1-2 days after delivery at admission room. Each interview lasted about 25 minutes average. I have interviews one time with each subject. The record was taken with the consent of the subject. Data were analyzed by means of Giorgi's phenomenological analysis methods and categorized according to the similarities of its contents. The investigator read the data repeatedly to identify and categorized themes and main meaning. Eleven themes of labor pain as experienced by these subjects were : 1) fear 2) suffering 3) evasion of pain 4) will power about overcome 5) support need 6) apprehension of parent 7) producing confidence 8) obtain his roles 9) attributing the cause of labor pain to others 10) not feeling of touching 11) ambivalence. Five main meaning identified were : 1) fear 2) evading and confrontation 3) the maturity of personality 4) unreality 5) ambivalence. The significes of this study for nursing are : 1) It enables nurses and other health care providers understand more clearly the lived experience of labor pain. 2) It provides that the way of more effective pain management.

This study was surveyed to assess the status of safety accidents occurred in work-places and prepare the fundamental data and prevent the safety accidents. The authors reviewed and analysed the charts of accident cases treated at a primary care clinic in A city from January 1991 to December 2006. The data were classified according to the USA Standards Institute and International Labour Organization method. We analyzed the data using SPSS program. The results were as follows : 1. The total cases of accidents were 455 for 8 years. 2. Accidents were mostly common in the workers who are in thirties and forties age(84.4%). 3. As season variation, spring and summer were common than others, but there was no statistical significance on season, month and weekday. 4. The most frequent injured part of the body were hand and finger, which was 36.0% among total cases. 5. According to the accidents type, cases of caught in, under or between were most frequently observed as 53.9% of the total cases. 6. The most common source of injuries was power machine(50.5%). 7. According to the unsafe acts, cases of carelessness and unsafe information were most frequently observed as 71.2% of the total cases. 8. Admission rate(5.5%) and official report rate(2.2%) were very low rate. As above results, the authors recommend to prepare the systemic control programs on environmental and human factors of safety accidents such as improving the working conditions, working facilities, working methods and safety education, and control of working time for working day.

Purpose: Trauma systems have been shown to decrease injury-related mortality. The present study aimed to compare the mortality rates of patients with major trauma (injury severity score >15) treated before and after the establishment of a level I trauma center. Methods: During this 20-month study, participants were divided into pre-trauma center and trauma center groups, and trauma and injury severity score (TRISS) method was used to compare mortality rates during 10-month periods before and after the establishment of the trauma center (October 2013 to July 2014 vs. October 2014 to July 2015). Results: Of the 541 total participants, 278 (51.5%) visited after the establishment of the trauma center. The Z and W statistics indicated better outcomes in the trauma center group than in the pre-trauma center group (Z statistic, 2.635 vs. -0.700; W statistic, 4.640). The trauma center group also exhibited meaningful reductions in the time interval from the emergency department (ED) visit to emergency surgery (118.0 minutes vs. 142.5 minutes, p=0.020) and the interval from the ED visit to intensive care unit admission (202.0 minutes vs. 259.0 minutes, p=0.035) relative to the pre-trauma center group. Conclusions: The TRISS and multivariate analysis revealed significant improvements in survival rates in the trauma center group, compared to the pre-trauma center group.

The fundamental concerns of this paper are to analyze the effects of student course evaluation using subject characteristic and student characteristic variables. We use a 2-level hierarchical linear model since the data structure of subject characteristic and student characteristic variables is multilevel. Four models we consider are as follows; (1) null model, (2) random coefficient model, (3) mean as outcomes model, (4) intercepts and slopes as outcomes model. The results of the analysis were given as follows. First, the result of null model was that subject characteristics effects on course evaluation had much larger than student characteristics. Second, the result of conditional model specifying subject and student level predictors revealed that class size, grade, tenure, mean GPA of the class, native class for level-1, and sex, department category, admission method, mean GPA of the student for level-2 had statistically significant effects on course evaluation. The explained variance was 13% in subject level, 13% in student level.

Objective : The purpose of this study is to evaluate the associations between 30-day mortality and various radiological and clinical factors in patients with traumatic acute subdural hematoma (SDH). During the 11-year study period, young patients who underwent surgery for SDH were followed for 30 days. Patients who died due to other medical comorbidities or other organ problems were not included in the study population. Methods : From January 1, 2004 to December 31, 2014, 318 consecutive surgically-treated traumatic acute SDH patients were registered for the study. The Kaplan-Meier method was used to analyze 30-day survival rates. We also estimated the hazard ratios of various variables in order to identify the independent predictors of 30-day mortality. Results : We observed a negative correlation between 30-day mortality and Glasgow coma scale score (per 1-point score increase) (hazard ratio [HR], 0.60; 95% confidence interval [CI], 0.52-0.70; p<0.001). In addition, use of antithrombotics (HR, 2.34; 95% CI, 1.27-4.33; p=0.008), history of diabetes mellitus (HR, 2.28; 95% CI, 1.20-4.32; p=0.015), and accompanying traumatic subarachnoid hemorrhage (hazard ratio, 2.13; 95% CI, 1.27-3.58; p=0.005) were positively associated with 30-day mortality. Conclusion : We found significant associations between short-term mortality after surgery for traumatic acute SDH and lower Glasgow Coma Scale scores, use of antithrombotics, history of diabetes mellitus, and accompanying traumatic subarachnoid hemorrhage at admission. We expect these findings to be helpful for selecting patients for surgical treatment of traumatic acute SDH, and for making accurate prognoses.
Adaptability is an important issue in video streaming over mobile environments, since the clients may request videos with great differences in their workload. In this paper, we propose the issues in limited bandwidth scheduling for efficient MPEG-4 video stream transmission over a mobile or wireless network. In the phase of admission control, the amount of bandwidth allocated to serve a video request is the mean bandwidth requirement of its requested video. The dynamic allocation of bandwidth in the phase of scheduling depends on the playback buffer levels of the clients with an objective to make it more adaptive to the playback situation of individual clients. In the proposed RTA scheduling protocol, more bandwidth may be allocated temporarily to the client whose buffer level is low. By employing the buffer level based scheduling policy, this protocol attempts to maximize the real-time performance of individual playback while minimizing the impact of transient overloading. Extensive simulation experiments have been performed to investigate the performance characteristics of the RTA protocol as comparing with BSBA protocol. This RTA protocol shows the better performance by transferring more frames than BSBA protocol.Computer simulations reveals that the standard deviation of the bit rate error of the proposed scheme is 50% less than that of the conventional method.
The Cancer Patients are rapidly growing and it became one of the main cause of death. Lately with the effect of Chemotherapy, drastically improved patients quality of life and also Prolonged Life of Cancer Patients. But the Chemotherapy not only Kill the Cancer cells but also harm to normal cells witch Cancer lots of side effect. This study was designed to identify the effectiveness of patient education to reduce side effect and help promote self care. The date was collected from October, 2001 to February, 2002 by questionary Survey Method. The subjects were 24 patients Who were and Anti Chemotherapy C University Hospital. Educated booklet contained what is Chemotherapy, what are the side effects, and to promote Self care, Pre test was given after 3-4 weeks re admission period. Analysis data was done by SPSS Program Paired t-test was used to differentiate Knowledge and difference of performing self care. Relationship in between Knowledge and promoting Self care was used Pearson Correlation. As the result of education, knowledge of self care and performance was drastically increased but the relationship in between knowledge of self care performed was not significant. Therefore it is proposed as follows: 1) Further research with experienced subjects to differentiate experience group and control group. 2) Education program need to be develop and standardize for anti cancer Chemotherapy patient. 3) During 6 cycle of Chemotherapy what is ideal number of in order to get the best result.
The purpose of this study was conducted to investigate factors influencing college adjustment on nursing freshmen in the distance education during COVID-19. A final sample 165 nursing freshmen was selected from S city, between 31 August and 4 September 2020. Using SPSS program t-test, one-way ANOVA, Pearson's correlation analysis and multiple regression analysis were performed. Factors that influenced college adjustment age, education at the time of admission, motivation of department choice, scholastic achievement. College adjustment showed a positive correlation with academic self-efficacy, critical thinking disposition, problem solving ability. These factors affecting the college adjustment of the subjects were with an explanatory power of 37.7%. Nursing freshmen need to method of class and student guidance that take these factors into account in the distance education during COVID-19.
Even in the hands of the expert endoscopists, an occasional instrumental perforation of the esophagus occurs. But instrumental perforation of the esophagus should not be difficult to diagnose if the possibility is borne in mind. Occasionally patient with esophageal perforations show little reaction at first, but usually they develop systemic manifestation if surgical management is delayed. Early surgical drainage of esophageal perforation is very important & effective therapeutic method. The delayed surgical treatment of esophageal perforation would have increased the morbidity & mortality by allowing mediastinitis & empyema thoracis. We have experienced 6 cases of delayed surgical management of instrumental perforation of esophagus from May 1974 to April 1986 in the department of thoracic and cardiovascular surgery, Yonsei University, college of the medicine. The ages ranged from 4 years to 57 years. The underlying esophageal diseases consisted of esophageal stricture in 3 cases, foreign bodies in the esophagus in 2 cases and esophageal ca. in one case. Most clinical manifestations on admission were high fever, chest discomfort, chest pain, dysphagia and subcutaneous emphysema. Most complications due to esophageal rupture were acute mediastinitis with or without empyema thoracis. Failure to diagnose promptly and failure to promptly institute adequate treatment undoubtedly were largely responsible for this patients death. All 6 patients had been taken delayed surgical drainage more than 24 hours following esophageal perforation. One patient had been in the open drainage state for long time and the another patient has been in the tracheostomy with postintubation vocal cord ulceration. The third patient died due to respiratory failure and sepsis due to fulminant mediastinitis & empyema thoracis. Even if the patients with esophageal perforation have been taken delayed surgical management, the patients should be survived with aggressive & effective surgical drainage with intensive post-operative care.
Purpose: The aim of this study was to investigate the prevalence of depressive symptoms in stroke patients and to compare characteristics of different rating scales - Hamilton Depression Rating Scale (HDRS), Beck Depression Inventory (BDI) and Hospital Anxiety and Depression Scale-Depression (HAD.D)- with regard to diagnosis and severity assessment for post-stroke depression. Methods: Participants included 44 stroke patients who could communicate. At admission, all study participants received a semi-structured interview using the HDRS and a self-completed questionnaire using the BDI and the HAD-D. Pearson's correlation method was used to examine associations among the three depression scales. The BDI and HAD-D were compared based on HDRS criteria, and the sensitivity and specificity using cut-off values were analyzed. Results: The HDRS showed that 52.30% of stroke patients had depressive symptoms on the BDI and HAD-D it was 59.10%. The HDRS correlated significantly with the BDI (r=0.81, p<0.01) and HAD-D (r=0.55, p<0.01). The BDI correlated significantly with HADS (r=0.50, p<0.01). After calculating the area under the ROC curve to decide on HDRS criteria, the BDI (AUC=0.91, 95% CI: 0.83.0.99) showed a significantly larger area compared to the HAD.D (AUC=0.82, 95% CI: 0.69-0.94). The cut-off value of the BDI was 12.50 points with a sensitivity of 81.00% and a specificity of 76.20%. Conclusion: These findings show that the BDI is a useful screening test for depression that most closely predicts the HRDS score.
