Atmospheric pressure in a tunnel rises in proportion to the square of train’s speed as it enters a tunnel. This pressure difference propagates into the train and cause aural discomfort to the passengers. In order to alleviate the aural discomfort of them. a new ventilation system has been designed and tested. This system controls the charged and discharged by flow rate by detecting the air pressure generated outside and inside of the train. Test to confirm the fundamental performance of the system was carried out. Consequently, this system was found to be able to alleviate the aural discomfort effectively. Application of the system to TGV-K running in the speed range of 350km/h is considered to have good propospect.

Purpose: This descriptive correlational study was intended to analyze the relationship among menopausal symptoms. competency of self-care agency and social support in middle-aged women. Methods: Participants in the study were 140 women who were 45-60 years of old. Data were collected using structured questionnaires and analyzed using descriptive statistics., t-test, ANOVA, $Scheff{\grave{e}}^{\prime}s$ test and Pearson correlation coefficients. Results: The frequency and discomfort of menopausal symptom were low, but the mean discomfort score were higher than frequency score. Middle-aged women with lower competency of self care experienced more frequent menopausal symptoms (t=-0.28, p=.001) and more discomfort (t=-0.24, p=.004). However, There was no significant difference in menopausal symptoms according to social support. Conclusion: Nursing interventions to enhance competency of self-care agency in middle-aged women are required in order to reduce the discomfort of menopausal symptoms.

Purpose: The purpose of the study was to evaluate the effects of postoperative oral care using cold therapy on nausea, vomiting and oral discomfort after laparoscopic myomectomy. Method: The study was conducted with an experimental group (n=29) and a control group (n=35) sampled from patients admitted to a women's hospital in a metropolitan city in Korea. Data were collected between October 10, 2011 and January 31, 2012 and analyzed using Chi-square, Fisher's exact test, t-test, and repeated measure ANCOVA with SPSS/WIN 19.0. Results: After the intervention, postoperative nausea (p<.001) and oral discomfort for patients in the experimental group were significantly lower than in the control group. There were significant differences in the presence of vomiting between both groups at 12 hours (p<.001) and 24 hours (p=.003) after leaving the recovery room. Conclusion: Oral care using cold therapy was found to be an effective nursing intervention for reducing postoperative nausea, vomiting and oral discomfort up to 24 hours after recovery in patients with laparoscopic myomectomy.

Purpose: This study was intended to examine an effect of taping therapy for adults suffering from ankle pain. Method: A non-equivalent control group pretest-posttest design was used for the study. An experimental group had 32 subjects and a control group 23 subjects. Subjects from the experimental group were taped for 24 hours and thereafter their range of motion [ROM], pain, and discomfort in the injured ankle were evaluated. SPSS Windows was used for data analysis. Result: The degree of ROM of the taped experimental subjects was greater compared to that of non-taped control subjects. The score of ankle pain of the taped subjects was lower than that of non-taped subjects. The score of ankle discomfort of the taped subjects was lower than that of non-taped subjects. Conclusion: This taping therapy can be used independently by nurses as an effective nursing intervention to decrease ankle pain and discomfort after the injury of ankle, which would contribute to expanding a realm of nursing.

In this study, it is investigated the relationship between sitting discomfort and major design variables of lumber support, such as prominence, height and width through volunteer tests. Korean $50^{th}$ percentile males and American $50^{th}$ percentile males are recruited among 36 to 45 years old peoples who have driving experiences and have no back pain during the past 12 months. Subject ratings are asked by changing design variables randomly. Body pressure and lumber position changes are also measured as object measures. And correlation among subject ratings, object measures and three design variables are analyzed using statistical analysis. As a result, it is revealed that prominence is the most dominant factor that correlates to the discomfort strongly for both-Koreans and Americans and contribution of other two variables are very low.

Purpose: The purpose of this paper was to identify blood pressure, interdialytic weight gain, thirst and intradialytic discomfort in subjects after applying individual low-sodium dialysis fluid (1,2,3 mEq/L) to hemodialysis patients for 12 weeks. Methods: This study was a non-equivalent pre-post design. For 12 weeks, dialysate concentration was maintained at 1 mEq/L or 2 mEq/L or 3 mEq/L based on average sodium concentration of each individual, and the difference was compared after applying individually. Results: Change in blood pressure significantly decreased in the group where in pre-hemodialysis systolic pressure decreased the gradient of sodium concentration in serum sodium and dialysis solution by 2mEq/L. Interdialytic weight gain, and thirst showed significant decrease in all three groups. But in all three groups, intradialytic discomfort among dialysis showed no significant changes. Conclusion: Although application of low sodium dialysis fluid showed no change in intradialytic discomfort, lowered blood pressure, thirst, and interdialytic weight gain, which could be used for individual showing increased interdialytic weight gain and increased blood pressure. There is need for continued study on this.

Background: Hearing protection devices (HPDs) are often used in the workplace to prevent hearing damage caused by noise. However, a factor that can lead to hearing loss in the workplace is improper HPD fitting, and the previous literature has shown that instructing workers on how to properly insert their HPDs can make a significant difference in the degree of attenuation. Methods: Two studies were completed on a total of 33 Hydro One workers. A FitCheck Solo field attenuation estimation system was used to measure the personal attenuation rating (PAR) before and after providing one-on-one fitting instructions. In addition, external ear canal diameters were measured, and a questionnaire with items related to frequency of use, confidence, and discomfort was administered. Results: Training led to an improvement in HPD attenuation, particularly for participants with poorer PARs before training. The questionnaire results indicated that much HPD discomfort is caused by heat, humidity, and communication difficulties. External ear canal asymmetry did not appear to significantly influence the measured PAR. Conclusion: In accordance with the previous literature, our studies suggest that one-on-one instruction is an effective training method for HPD use. Addressing discomfort issues from heat, humidity, and communication issues could help to improve the use of HPDs in the workplace. Further research into the effects of canal asymmetry on the PAR is needed.

Objectives: This study aims to examine factors affecting depression of Older Adults by using the data of the elderly survey conducted by the Korea Institute of Health and Social Affairs in 2020. Methods: The total sample was 4,777 people aged over 65 years old. In this study, sociodemographic variables, information devices'use behavior and discomfort variables were input to examine the effect on depression. The data was analyzed with t²-test, ANOVA and hierarchical regression by SPSS statistic program. Results: First, use behavior and discomfort of information devices and depression were significantly different by sociodemographic variables(sex, age, level of education, marital status). Secondly, regression analysis showed that age and level of education affected an influence on depression in Model 1, which analyzed only sociodemographic variables. However, Model 2, which analyzed devices' use behavior and discomfort variables at the same time, showed that they affected depression. Conclusions: It was suggested to develop customized health education and mental health promotion were needed to reduce depression in the elderly.
