Purpose: To examine the difference of physical discomfort and childbirth satisfaction between postpartum women with and without having taken Epidural Analgesia. Method: The subjects were divided into one group of 128 primipara taken Epidural Analgesia and the other of the same 70 women who were not taken it. Data were collected by questionnaires of their own physical discomfort and birth satisfaction at postpartum 1 to 2 days in OBGY hospitals, and data were analyzed using SPSS Program. Result: Women having taken epidural analgesia appealed higher physical discomfort than those without it in the lower limbs exercise discomfort, difficult urination, urinary retention, nausea & vomiting, whereas appeared vice versa in breast pain. Among indicators for childbirth satisfaction, women having taken epidural analgesia preferred the same delivery method later again more than those without it. Conclusion: It is confirmed that the method of epidural analgesia is not an absolute way to control labor pain, rather stir physical discomfort after childbirth and does not fully increase the women's childbirth satisfaction. Therefore, it is proposed that nurses should provide the pregnant women the right knowledge and information, thereby enabling them to select the useful method of childbirth to their own course of childbirth and health-recovering after the delivery.

Purpose: The aim of this study was to investigate whether job satisfaction in clinical nurses was dependent on work intensity and whether physical discomfort mediated the relationships between these variables. Methods: Structural equation modeling was used with a sample of 253 clinical nurses from four general hospitals. In the model, absolute work intensity, relative work intensity, and flexibility were considered as exogenous variables and physical discomfort as a mediating variable. Data were collected using self-report measures such as the Labor Intensity Questionnaire, the Rating of Perceived Exertion, and the Index of Job Satisfaction. Results: The results of the structural equation modeling found that the higher scores on absolute and relative work intensity were positively associated with physical discomfort but only relative work intensity was significantly related to job satisfaction. Physical discomfort mediated the relationships between absolute work intensity and job satisfaction and between relative work intensity and job satisfaction. Among three kinds of work intensity, only relative work intensity had direct and indirect effects on job satisfaction. Conclusion: The findings suggest that increase in relative work intensity might play an important role in decreasing job satisfaction in clinical nurses and a reasonable reward system considering relative work intensity could be necessary.

Background: Prolonged neck flexion during smartphone use is known as a factor of neck pain and alteration of neck muscle activity. Studies on the effects of shoulder taping on neck discomfort and neck muscle responses while texting on a smartphone are still lacking. The aim of this study was to examine the effects of shoulder taping on neck discomfort using a numerical rating scale, and neck muscle activity and fatigue using a surface electromyography during a texting task on a touchscreen smartphone. Methods: Twenty-five healthy adolescents used the dominant hand to perform a 30-minute texting task using a touchscreen smartphone at two separate times under one of the following two conditions: taping across the upper trapezius muscle and no taping. Neck discomfort, normalized root mean square, and normalized median frequency slopes for upper trapezius, cervical erector spinae, and sternocleidomastoid muscles were recorded. Results: The results revealed that shoulder taping provided significantly lower neck discomfort than no taping (p < 0.001). However, shoulder taping did not significantly alter normalized root mean square and normalized median frequency slope values of all muscles when compared with no taping controls. Conclusion: Shoulder taping reduces neck discomfort but does not affect neck muscle activity and fatigue while texting on a touchscreen smartphone.

Objective: The purpose of this study was to evaluate Korea's Honam express train's first- and second-class seat discomfort by using pressure measurement, subjective discomfort rating, and physical compatibility. Background: Over the years, the demand for an express train service is continually increasing. A comfortable ride is important to achieving passenger satisfaction. A train seat plays a significant role in fulfilling passenger seating comfort. With this in view, a field survey and pressure measurements were performed on the selected train seat. Method: The pressure ratio at the body-seat interface (thigh and buttock regions) was measured by the pressure mat system. The interface pressure ratio was calculated and compared. The subjective discomfort rating scale was used to evaluate the subjects' overall feeling. The dimensions of train seats were analysed according to the anthropometric and demographic characteristics of the population data from Size Korea. Results: The results highlighted that the interface pressure ratio was greater while participants sat on the second-class seat than the first-class seat in the left- and right-side thigh regions. Also the pressure ratio was greater for the participants in the 1st~25th percentile height groups (149.8~160.8cm). The subjects rated higher discomfort for the second-class seat than the first-class seat. The physical compatibility results showed that the second-class seat's breadth was inadequate for the 95th and 99th percentile male. Conclusion: Overall, interface pressure measurement, subjective discomfort score and physical compatibility results showed that the second-class seat was more uncomfortable for the passengers than the first-class seat. Application: The adopted methodologies could be used to measure the seating comfort of the train seats.

Purpose : To collect and interpret basic data involving the discomfort level of platelet donors and to see which nursing interventions would help make plateletpheresis more comfortable. Methods : Using "the Platelet Donor's Discomfort Scale" developed by the researcher herself and reviewed by an expert panel, the severity of discomfort as well as factors contributing to the development of this discomfort were analyzed. This scale contained 59 items and each item was scored by the 4-point Likert manner. Between March 1, 1996 and May 31, 1996, 500 platelet donors(16 years of age and older) were enrolled in this study. The Statistical methods used were factor analysis, t-test, and ANOVA. The results were as follows : 1. The mean of the platelet donor's discomfort scale was 130, range 69-207, possible score ranging from 59-236. 2. The platelet donor's discomfort scale had psychological, environmental, physical, and time-related factors. The time- related factor was the highest positive correlation with the development of the discomfort. 3. In looking at the psychological and environmental factors of the discomfort scores, the 16-20 age group had significantly higher ratings than those of the 26-30 age group. The students' group had higher scores than the soldier's group, and those who used the V-50, MCS -3P, or the PCS Plus machines had higher scores than those who used the COBE Spectra machine(P<.05, respectively), 4. In relation to the physical factor of the discomfort score, the youngest group felt significantly more discomfort, the student's group had a higher score than the soldier's group, and those who used the V-50, MCS-3P, or or the PCS Plus machines had higher scores than those who used the COBE Spectra machine(P<.05, respectively). 5. The time related factor of the discomfort score had the highest scores in every variable, however, statistically significant differences were not found between any of the variables(P>.05). Conclusion : Based on the above results, it can be oserved that the time-related factor was the most important factor influencing discomfort. The age and job of the donor, as well as the type of machine used, were significant variables in predicting the level of discomfort, regardless of psychological, environmental, and physical factors. This data could be used to determine nursing interventions that would relieve some of the discomfort of patients, as well as donors, undergoing plateletpheresis. Furthermore, consideration of the donor's time, introduction of a platelet donor pool system, publicity and education about platelet donation are required.
