Backgroud : Now a days, most studies for professional voice user have been performed after artificial voice abuse without consideration of environmental and personal factors, and occupational specificity, therefore those studies have some problems. Objectives : To make a basic guideline for the management of untrained professional voice user, practically we ananalyzed the voice of experimental group. Materials and methods : Just after working, the sustained vowel sounds of the 15 female telephone operators (subjective group) and the 20 normal female persons (control group) were analysed, using a history paper, acoustic analyzer and videostroboscopy. Results : The most common symptom in subjective group was dysphonia. Stroboscopic findings in subjective group were as following ; posterior chink 11 cases (73%), incomplete closure 2 cases (13%), anterior chink 1 case (7%). The mean maximal phonation time in telephone operators was 12.8 seconds and in control group was 16.8 seconds. Jitter, pitch pertubation quotient (PPQ), shimmer and amplitude pertubation quotient (ASQ) were significantly increased in subjective group than control group, but there is no difference between two group in fundamental frequency and noise to harmonic ratio. Conclusion : Untrained professional voice user needs professional career guidance and counseling. And when we manage the untrained professional voice user, we should consider specific occupational, personal and environmental factors as well as laryngeal factors.

Background: This study is aimed to evaluate the level of fear and to reduce the overall fear, thereby enabling patients to receive treatment via timely visits. Methods: In a survey conducted by 460 South Korean middle school students, we used 453 data that faithfully responded to the survey. Multiple regression analysis was conducted to investigate the factors influencing subjective oral health and dental fear. The significance level used for statistical significance was ${\alpha}=0.05$. Results: The level of fear was higher for upper grade, female students. The factors affecting dental fear were higher for gingival bleeding and dental pain. Regarding factors for dental fear affecting subjective oral health, lower fear of puncture needle and tooth removal tool resulted in higher subjective oral health. Conclusions: The study found that adolescents had higher fear of dental care when they had gingival bleeding and tooth pain. Gingival bleeding is a symptom of early gingival disease and dental pain is likely due to advanced dental caries. These results suggested that it is necessary to have a program to reduce dental fear and anxiety as well as a program to prevent dental diseases through regular periodic screening and education.

The purpose of this study was to investigate the correlation between wearing masks and subjective symptoms of halitosis in the COVID-19 situation. The survey was conducted from June 15 to July 31, 2022, among university students aged 19 years or older in Daegu and Gyeongbuk, 1. Subjective symptoms of halitosis were found to be higher in males and students being treated for periodontal diseases. 2. The subjective symptoms of halitosis were found to be higher in subjects with psychological anxiety, even though they did not have halitosis. 3. As a result of examining the subjective symptoms of halitosis, it was found that there were more subjects who were aware of halitosis while wearing a mask than those who were not. In view of the above results, it is thought that because of prolonged wearing of masks due to the COVID-19 pandemic situation, the difficulty faced in oral health management increases the symptoms of halitosis. Therefore, it is considered that oral health education in the era of corona should be accompanied by proper wearing of masks and halitosis management education.

Purpose: This study aimed to define the relationship among self-care, symptom experiences, and health-related quality of life(HRQoL) according to the severity of disease in chronic obstructive pulmonary disease(COPD) patients. Methods: The participants, 195 COPD patients, were recruited at a pulmonology clinic of a universityaffiliated medical center in B metropolitan city. Inclusion criteria were patients who were diagnosed as COPD and had less than 0.7 of $FEV_1$/FVC(Forced Expiratory Volume for 1 second/Forced Vital Capacity) ratio. The severity was classified with GOLD(Global initiative for Obstructive Lung Disease) stages, $FEV_1%$ predicted value from mild to very severe. The data were gathered by the medical records and self-reported questionnaires. Results: The self-care, symptom experience, and HRQoL were all significantly different by COPD severity based on pulmonary function(p<.05). There were significant moderate negative relationships between symptom experiences and self-care(r=-.54, p<.001) and between symptom experiences and HRQoL(r=-.64, p<.001). There was a moderate positive correlation between self-care and HRQoL(r=.63, p<.001). Conclusion: It suggests that the assessment of disease severity based on pulmonary function and subjective symptom experience in patients with COPD may be a key component to develop a tailored self-management program and to improve their quality of life.

To investigate industrial fatigue and low back pain, the questionaire survey for subjective symptoms of fatigue and low back pain was carried out among 591 male workers aged 20-55 employed in an automobile industry in Korea. Workers participated to this study were divided into low back pain group(LBP) and control group, according to the self-reports by written questionaires. The subjective sysptoms of fatigue comprised three groups of 10 items each, representing dullness and sleepiness(level of cerebral activation), difficulty in concentration(level of motivation) and bodily projection of fatigue. The resultant data were processed for $\chi^2-test$, t-test and a pearson's correlation coefficient to confirm the relationships. The results were as follows: 1. 30 items of fatigue subjective symptoms exeptone item, 'lack in perseverance', were directly associated with low back pain. 2. The percentage of fatigue complaint were sig nificantly higher in LBP group. 3. Of the 30 items of fatigue subjective symptoms, the highest percentage was accounted for 'eye strain'(27.9%), followed by 'whole body feels tired' and 'legs feel heavy'(22.9%), 'feel like lying'(21.4%), 'feel a pain in the low back'(18.7%), 'feel drowsy'(16.4%) and 'feel stiffness in the neck or the shoulders'(16.2%) in the order of sequence. 4. The average weighted score for the first group of fatigue items(dullness and sleepiness) was the largest among three groups and was followed by the second group(difficulty in concentration) and the third group(bodily projection of fatigue) in the order of sequence, suggesting the heavier shift work stress of the workers. 5. In the groups of the aged 30-40, work duration of 5-7yrs, heavy work amount and irregular work speed, significant high fatigue complaints were revealed in terms of eye strain, whole body feels tired, legs feel heavy, feel like lying, feel a pain in the low back and feel stiffness in the neck or the shoulders. 6.
