  • This paper analyzes qualitatively the stereo 3D content factors causing viewer's discomfort. For this, we perform a subjective test that each subject strokes a specific key whenever he (she) feels discomfort during watching a stereo 3D contents. Also we extract the data for the factors in the 3D contents to obtain their quantitative values and the amounts of the temporal changes. Those two sets of data are used to analyze the contents to find the factors which cause viewer's discomfort. The factors to be considered are the amount and the frequency of the disparity changes, story of the contents, situation or environments of a scene, movement and the position of the camera, color and luminance information as well as disparities themselves. We analyse the various strong and weak factors and their composites to find how much discomfort each factor or composite causes. We also show the situations and their related factors that causes less discomfort than the amount of their disparities.

  • The purpose of this study was to identify chronic diseases and oral health care behaviors in 65-year-old individuals and to determine the factors that influence masticatory mobility. The raw data from the 8th National Health and Nutrition Examination Survey in 2020 were utilized to analyze factors associated with chewing discomfort in 1,278 elderly Koreans. Using IBM SPSS Statistics 27.0, we conducted complex sample cross-analysis to examine the difference in chewing discomfort based on general characteristics, chronic diseases, and oral health care behaviors. Additionally, we performed complex sample multiple logistic regression analysis to identify the factors associated with chewing discomfort. As a factor influencing chewing discomfort, unmet dental care was 3.33 times higher (p<0.001), and subjective oral health was 0.18 times more likely to be moderate (p<0.001) and 0.48 times more likely to be good (p<0.001) lower. In the case of arthritis, the level of chewing discomfort was high (OR=1.08, p=0.694), but there was no significant difference. As a result of the aforementioned factors, it is believed that there is a need for policies and systems to provide dental care to the elderly before their oral health deteriorates. Additionally, tailored oral health promotion programs should be implemented.

  • Purpose: The purpose of this study was to identify associated factors of chewing discomfort among community-dwelling elderly. Methods: The study was cross-sectional design and secondary data analysis using the 6th Korea National Health and Nutrition Examination Survey. Among the total of 7,550 participants, data was analyzed with 1,126 adults aged 65 years and over. Chewing discomfort was assessed by the perceived chewing discomfort. Multivariate logistic regression analysis was used to find the associated factors of chewing discomfort. Results: Along with 61.7% of the participants reported having chewing discomfort, 85.2% reported to perceive poor oral health and 35.0% had oral pain. In multivariate logistic regression, perceived oral health (OR 3.22, 95% CI 2.24~4.63), oral pain (OR 2.46, 95% CI 1.76~3.43), activity limitation (OR 1.71, 95% CI 1.05~2.80), teeth requiring treatment (OR 1.61, 95% CI 1.14~2.26), number of remaining teeth (OR 1.60, 95% CI 1.22~2.10) and educational level (OR 1.56, 95% CI 1.15~2.12) were the significant predictors of chewing discomfort. Conclusion: The prevalence in chewing discomfort was high in elderly Koreans and various factors were associated with chewing discomfort. To improve chewing ability, it is suggested that the national level of policies offer strategical oral health programs in this population.

  • Purpose: The purpose of this study was to identify the factors that predict discomfort after coronary angiography or percutaneous coronary intervention (PCI) among hospitalized patients. Methods: A total of 203 patients who underwent coronary angiography or PCI were recruited from C hospital located in S city, J province, from June through August 2008. The level of discomfort was measured and standardized by two instruments, discomfort questionnaire and the Visual Analogue Scale (VAS). Results: Stepwise multiple regression showed that the factors predicting the level of discomfort were type of angiography, gender, previous angiography, dysuria, pre-information, and sleep satisfaction, which together explained 30.6% of the total variance of the level of discomfort. Conclusion: Patients who had previous experience with these procedures, received a pre-information about the upcoming procedure, had no dysuria, and had slept well after the procedure were less likely to complain discomfort. Pre-informed education should be given by nurses to patients who will have an angiography or PCI to reduce their physical and emotional discomforts.

  • 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.

  • This study investigated perceived discomfort and reasons related to use three information technology products (personal computer, mobile phone and digital television remote controller), and extracted the universal design factors. 240 people (30 females and 30 males for four age groups) participated in the one-to-one interview type of questionnaire, and replied to degree of discomfort at level of items and the reasons of discomfort at level of detailed elements for each product. As a result, almost all age groups answered that using input buttons of mobile phone and remote controller and watching display of mobile phone caused discomfort. Binary logistic regression of the detailed elements showed that response rate of discomfort mostly increased with age, except for specific elements such as shape of mouse and remote controller, and location of function button of mobile phone. Some of the detailed elements had high response rate of discomfort from all age groups. The age groups also showed similar tendency for the elements to select one alternative for the reason of discomfort, but not for sound volume and size of mobile phone and button sensitivity of remote controller. Finally, the universal design factors were extracted for each product based on the results, and divided into common factors and factors classified by the age group. Through this study, we identified using practices of various age groups and their demands for the products. It is expected that extracted detailed elements can be considered as important design factors to design the products universally.

  • Background : This study was attempted to provide a basic information necessary for the development of measures evaluating perceived discomfort of the patients under local anesthesia and the developments of nursing intervention and nursing standard. Method : The study subjects were a convenience sample of 100 surgical patients under local anesthesia. The researcher visited the patients directly and explained the purpose of the study to them. Then they were asked to fill out questionnaires which were developed and structured by the researcher, under their prior permission. Out patient's data were collected at recovery room after operation. Results : Factor analysis on measures evaluating the patients under local anesthesia showed that the measures consisted of eight factors including "explanation", "humane treatment", "motion limitation", "pain", "no togetherness", "waiting", "the environment of operating room", and "unkindness". When analyzing each of the factors regarding their degree of contribution to perceived discomfort, it was found that "waiting" was highest in terms of the degree. According to general chara-cteristics of the sampled patients, the factor of "explanation" contributed to perceived discomfort more in male patients than female ones. Regarding parts of medical examination, the patients of otorhinolaryngology felt perceived discomfort most because of the factor of "pain". Conclusion : To relieve perceived discomfort the patients under local anesthesia require providing individually systematized nursing services which can reduce perceived discomfort according to each of the factors. In doing so, an unlimited attention and much effort should be given to realize CQI reaching the dimension of increase in comfort as well as decrease perceived discomfort.

  • This study was conducted to identify factors related to discomfort while speaking in the elderly and provide fundamental data for establishing oral health care policies for a healthy old age. Using the raw data from the 8th wave of the National Health and Nutrition Examination Survey (2020), we conducted an analysis to examine the relationship between speaking discomfort and mental health, as well as oral health care behavior, among 1,278 elderly individuals in Korea. Differences in speaking discomfort were analyzed based on general characteristics, mental health, and oral health care behavior using complex sample cross-analysis. Additionally, factors associated with speaking discomfort were analyzed using complex sample multiple logistic regression analysis. As a result, individuals with depression experienced higher levels of speaking discomfort (p<0.05), and individuals experiencing high levels of stress also reported higher levels of speaking discomfort (p<0.05). As a factor affecting speaking discomfort, it was found that speaking discomfort was 2.56 times higher (p<0.001) when dental care was not met, and speaking discomfort was 3.05 times higher (p<0.05) when teeth brushing was less frequent. As a result of the aforementioned findings, it is believed that a customized oral health promotion program is necessary to expand dental health insurance coverage for the elderly and improve oral healthcare.
