A quasi-experiment, repeated measures design with non-equivalent control group was used to test the influence of cold therapy on the perineal discomfort and the healing state of the postpartum women undergoing vaginal delivery with episiotomy. Experiment was carried out from July 28, through October 2, 1996 with 40 postpartum women conveniently sampled from one university hospital located in Seoul. The 40 postpartum women undergoing vaginal delivery with episiotomy were as signed to experimental and control groups evenly(20 each). The instrument of measurement of perineal discomfort was 0-10 rating scale that was made by researcher and that of perineal healing state was Davidson's REEDA tool. The perineal discomfort and the healing state level were measured before and after each treatment. The treatment using ice glove that was given for the only experimental group was carried out at three points ; as soon as returning to the recovery room, 3 hours after returning to the recovery room and 6 hours after returning to the recovery room. The data was analysed by using t-test, chi-square test to determine the similarity between experimental and control groups. The hypotheses were tested using repeated measures ANOVA. The results of this study are summarized as follows; 1. The first hypothesis that the perineal discomfort level of the experimental group will be significantly lower than that of the control group(df(1,38), F=24.12, p=.0001) was supported. 2. The second hypothesis that the perineal healing state of the experimental group wil be better than that of the control group(df(1,38), F=0.48, p=.49) was not supported. Based on the results of this study, could therapy was turned out to have significant effect on the perineal discomfort of the postpartum women undergoing vaginal delivery with episiotomy.

Purpose : The purpose of this study was to find effects of early oral water intake on thirsty feeling, nausea, and vomiting after ambulatory surgery. Method : Sixty patients who received PET(Pressure Equalizing Tube) insertion surgery under general anesthesia were conveniently sampled and divided into two groups. Experimental group was instructed to drink water after two hours and control group was directed to intake water after three hours postoperatively. Data were collected from May 1, 2002 to August 31, 2002 at ambulatory surgery center of Asan Medical Center. The thirsty feeling, nausea and vomiting score between experimental and control group were compared at the time of recovery, recovering consciousness, 2hr, 3hr, right before discharge and/or 24hr(telephone interview) postoperatively. The collected data were analyzed by SPSS 8.0 statistic program. Result : Result of this study are as follows. 1) There was a statistically significant difference(t=-10.31, p=0.00) in the occurrence of thirsty feeling at the 3hr postoperatively between experimental and control groups. 2) There was a statistically significant difference($x^2=6.66$, p=0.02) in the incidence of nausea during the 2hr postoperatively between experimental and control groups. 3) There was no difference($x^2=0.35$, p=0.55) between groups in vomiting scores. Conclusion : It was generally known that the delay of oral water intake decreases post operative complications. But, this study shows that early oral water intake decreases discomfort of thirsty and there was no adverse effects on the occurrence of postoperative nausea and vomiting.

Background: Tuberculosis (TB) causes substantial health burden to the Korean military. This study aims to assess the impact of infectious TB cases on close and casual contacts in the Korean Army settings based on contact investigation data. Methods: Six Army units with infectious TB cases from September 2012 to May 2013 were enrolled in the study. We analyzed the clinical data from close and casual contacts screened using the tuberculin skin test (TST) and QuantiFERON-TB Gold In-Tube to identify latent tuberculosis infection (LTBI) cases. For the control group, 286 military conscripts with no reported TB exposure were tested by TST only. Results: Of the 667 contacts of index cases, LTBI cases identified were as follows: 21.8% of close contacts of smearpositive cases (71/326), 8.5% of casual contacts of smear-positive cases (26/305), and 2.8% of close contacts of smearnegative cases (1/36). In the control group, 16.8% showed positivity in TST. In a multivariate analysis, having stayed in the same room or next room with TB patients was identified as a risk factor of LTBI. Conclusion: Using the data from TB contact investigations in the Korean Army units, we found an overall LTBI rate of 14.7% among the contacts screened. This study demonstrates that contacts living in the same building, especially the same room or next room, with TB patients are at a high risk of acquiring LTBI, serving as additional evidence for defining close and casual contacts of a TB patient with regard to Army barrack settings.

Unlike adults, cognitive ability and communication are not accurate in pediatric patients. Therefore movement due to psychological anxiety in X-ray photography is one of the factors that increase repeated irradiation. In order to minimize the rejection of X-ray and to improve the satisfaction of medical service, it is necessary to improve the environment of the radiological room to help psychological stability and to find a positive measure for reduction of radiation dose, including unnecessary. The subjects of this study were 186 pediatric patients from May to July, 2017, who were from 6 months to 36 months, The study group was set up a radiological room without auditory and visual environment changes is A group, except for changes in visual environment, the room where only auditory environmental changes were applied was group B, the auditory environment changes were excluded, and the room where only the visual environment change was applied was divided into group C, the auditory and visual environment changes were applied to the D. In group A, 10 retrospectives were obtained, 7 in group B, 5 in group C, and 2 in group D. Especially in group A and group D, statistically significant at p <0.053 In conclusion, hearing and visual environment changes affected the psychological stability of pediatric patient, and the repeated irradiation was reduced, thus improving the quality of medical services.

Background: Sternal infection after open heart surgery is a serious complication associated with high rate of mortality. We reviewed the effect of improved operating room and intensive care unit un the sternal infection by analyzing the incidence and condition of that around the movement of operating room and intensive care unit in July 1997. Material and method: We reviewed a total of 453 patients. Group I contains 237 patients who underwent open heart surgery between January 1997 and December 1978 before we moved the intensive care unit and of operating room, and Group II contains 216 patients who underwent open heart surgery between January 2000 and July 2001 after we moved. We only included adult patients over age 15 who underwent cardiopulmonary bypass through median sternotomy and excluded the mortality cases except sternal infections in this study. Result: Sternal infection developed in 18 patients(8.0%) in Group I, and in only 1 patient(0.49%) in Group II. Emergency operation, cardiopulmonary bypass time, operation tilde, transfusion, tracheostomy, and reoperation are significantly associated with sternal infection among the known risk factors. The logistic regression analysis containing those six factors revealed that the movement of intensive care unit and operating roots is effective on the decreasing sternal infection(p=0.029, 95% confidence interval 0.011 ∼ 0.788). Conclusion: Although there have been studies on manly risk factors associated with the sternal infection after open heart surgery, we think that the improvement of operting room and intensive care unit is a method for decreasing the incidence of sternal infection.

This study was designed to evaluate the analgesic effect of bee venom (BV) Acupuncture into different treatment points, Chok-samni (ST36) and blank loci of the gluteal muscle and back. We investigated neuronal activity in the spinal cord using the Fos immunohistochemical technique according to the pretreatment with different concentrations of BV, thirty minutes before the formalin injection. The results were summarized as follows: 1. The number of Fos-like immunoreactive (Fos-LI) neurons in L2 segment of the saline-formalin treated group was significantly increased in NECK and VENT of the spinal cord as compared with that of the room control group. However, there was no significant change in the number of the Fos-LI neurons in L2 segment of the BV-formalin treated group as compared with that of the room control group. 2. The number of Fos-LI neurons in L3-5 segment of the saline-formalin group was significantly increased in all the regions of 142 the spinal cord as compared with that of the room control group. However, the Fos-LI neurons in L3-5 segment of the BV-formalin treated group was dramatically decreased in all the regions of the spinal cord as compared with that of the saline-formalin group. Therefore, these results indicated that the BV acupuncture suppressed the nociceptive neuronal activities in L3-5 of the spinal cord induced by formalin injection. 3. There was a strong positive correlation between the formalin-induced pain behavior and the number of the Fos-LI neurons in L3-5 segment.

In this study, a new shielding method was applied to an accessory device that produces electromagnetic waves in the magnetic resonance room to prevent the generation of artifact caused by electromagnetic waves. The research method applied a new shielding made of metal plating fiber to patient surveillance CCTVs without shielding technology, and obtained and evaluated noise map when the power was not cut off and when the new shielding technology was applied without shutting down the CCTV. As a result of the study, it was found that there was at least one group with significant differences. Type I and type III belonged to group 1 while type II belonged to group 2 in the Post-hoc analysis, which meant blocking power of the CCTV and the applying new shielding technology were in the same group. In conclusion, if electromagnetic waves are generated due to additional accessories in the scanning room, the shielding material proposed in this study should be applied which enables the electric state become similar to type I, not generating noise, thereby preventing the artifacts caused by electromagnetic waves.

Purpose: The purpose of this study was to examine the effects of cold oral gargling on oral discomfort among Non-Hodgkin's lymphoma patient undergoing chemotherapy. Method: An quasi-experimental, nonequivalent control group design was used. Thirty two patients receiving chemotherapy at G hospital in P city were recruited from August 1, 2002 to October 20, 2002. Sixteen were conveniently allocated into the experimental group and 16 into the control group. Participants in the experimental group used cold oral gargling while their counterparts used room temperature oral gargling. Subjective and objective oral discomforts were measured by the instruments developed by Beck. The SPSS WIN 10.0 program was used to analyze the data with t-test, ${\chi}^2$ -test, and repeated measures ANOVA. Findings: The participants in the experimental group reported less oral discomfort and showed better oral conditions than those in the control group at the post 7th, 14th, and 21st days. Participants in the experimental group reported better oral conditions in taste, tongue, eating, and saliva than those in the control group. Conclusion: The cold oral gargling seemed to be more beneficial than room-temperature oral gargling in reducing oral discomfort for the Non-Hodgkin's lymphoma patients undergoing chemotherapy.

The purpose of this study was to examine the differences in skin temperature and thermal comfort of participants in a $19^\circ{C}$ room (the recommended room temperature in the winter) depending on age, sex and clothing weight. Subjects were divided into four groups (6 young males, 5 young females, 6 old males, 6 old females) and experimental trials consisted of three conditions: wearing underwear in a $19^\circ{C}$ room (19CUW), without underwear in a $19^\circ{C}$ room (19C), and without underwear in a $24^\circ{C}$ room (24C). The results indicated the following: 1) There were no significant differences in mean skin temperature based on age or sex, and the mean skin temperatures of the four groups were in the range of 32.4∼$34.0^\circ{C}$. 2) In the 19C condition, the skin temperatures of the hands and feet of old females were higher than those of the other three groups. 3) In terms of perceived thermal comfort, young females showed a tendency to feel the most uncomfortable. Both old and young groups agreed that the 24C condition was the most comfortable. 4) Relational coefficients between thermal comfort and skin temperatures were higher in the young group than in the old group. Furthermore, the perceived thermal comfort had a stronger relationship with mean skin temperatures than with local skin temperatures. 5) The mean skin temperatures of subjects who indicated they were 'comfortable' were in the range of 31∼$36^\circ{C}$ regardless of age or sex.

Purpose: The purpose of this study was to explore emergency room nurse's work experiences during the COVID-19 pandemic. Methods: Data were collected from 15 registered nurses working in the emergency room between October, 10th and December 15th, 2020, through focus group interviews and in depth interviews. Collected data were analyzed using Colaizzi's phenomenological method. Results: The study derived four categories and eight themes. The four categories are 'sense of cringing with fear', 'nursing in chaotic situation', 'lonely struggles', and 'career growth as a nurse'. Emergency room nurses experienced fear and confusion in the COVID-19 pandemic, but overcame the crisis and had positive experiences of professional growth as a nurse. Conclusion: To protect emergency room nurses from infectious disease and improve their professional quality of life during the COVID-19 pandemic appropriate education and healthcare resource should be provided. It is necessary to reflect clinical worker's opinions and improve the delivery system of guideline to reduce confusion in the field and develop practical infectious disease control guideline. Furthermore, better working conditions, appropriate rewards and social and mental support should be provided for nurses in emergency room.
