The purpose of this study was to examine the symptom of dry mouth of workers, their subjective oral symptoms and factors affecting their oral health-related quality of life (Oral Health Impact Profile, OHIP-14) in an effort to provide information on the development of oral health promotion programs geared toward workers. The subjects in this study were the workers in five different companies in North Jeolla Province. After a survey was conducted from August 1 to September 20, 2012, the collected data were analyzed. The findings of the study were as follows: The office workers got 2.59 in oral dryness, and the sales associates got 1.82. The oral dryness of the former was severer than that of the latter (p<0.001). The irregular workers got 2.05 in OHIP-14, and the regular workers got 1.82 (p<0.001). Symptom of dry mouth had a positive correlation to OHIP-14 (r=0.456). OHIP-14 was positively correlated with age (r=0.209) and negatively with academic credential (r=-0.136). OHIP-14 was more significantly affected when their symptom of dry mouth was severer (${\beta}=0.383$, p<0.001), when they were older (${\beta}=0.221$, p<0.001) and when they felt they had oral diseases (${\beta}=0.146$, p<0.01). In conclusion, quality programs should be developed to promote the oral health of industrial workers in consideration of the influential factors for the oral health-related quality of life of the workers, and the government should pay more attention to related policy setting to improve the oral health of industrial workers.

Background and Objectives : Voice disorders can cause problems in patients with benign vocal cord lesions emotionally, physically, economically and functionally. Neither subjective nor objective voice examinations can evaluate such factors adequately. The Voice Handicap Index (VHI) subjectively evaluates voice disorders in terms of physical, functional, emotional factors and measures the patient's perception of the impact of voice disorder. The purpose of this study is to evaluate the usefulness of VHI in the patients with benign vocal cord lesions. Materials and Method : The authors evaluated 37 patients who experienced laryngeal microsurgery for benign vocal cord lesions from september 2003 to August 2004. The VHI was used to measure the postoperative changes of the patient's perception and acoustic analysis and aerodynamic tests were also done. Statistical analysis was done using paired t-test and Pearson's correlation. Results : The VHI scores showed statistically significant reductions postoperatively. In acoustic analysis, jitter and shimmer had statistically significant reductions after surgery but noise-to-harmonics ratio did not. A statistically significant change in the average MFR and MPT perioperatively was found. The relationship between VHI and acoustic, aerodynamic analysis attained statistical significance. Conclusion : The VHI is a useful assessment tool to monitor the patient's self-perception of voice change after the surgery of benign vocal cord lesions. The VHI measurement, when combined with acoustic and aerodynamic analyses, will be helpful in comparing functional outcomes after voice surgery.

Based on data obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted by Korea Centers for Disease Control & Prevention (KCDC), this study analyzed the relationship between existence of the spouse, number of family members, and disease afflictions of the Korean elderly, and factors affecting their quality of life. The collected data were analyzed by Chi-square test, t-test and One-way Anova, using the SPSS / WIN 25. Our comparative analysis on the health status and quality of life revealed that individuals in the singles group had significantly more diseases than the married group. The singles group considered their health was subjectively poor, whereas the quality of life of the married group was higher. Analyzing the characteristics of chronic disease and activity restriction showed significantly higher prevalence of several diseases in the singles group. Besides, the singles group revealed significantly higher limitations of activity. Taken together, our results reveal a difference in the health status, quality of life, and the presence of chronic diseases in accordance to existence of the spouse, indicating that having a spouse increases the level of health and quality of life of the elderly.

Objectives: The purpose of this study was to investigate the associated factors of self-reported dry mouth in adults. Methods: A self-reported questionnaire was filled out by 249 adults in Seoul and Gyeonggi-do from June to October, 2014. The questionnaire consisted of general characteristics of the subjects, age, monthly income, smoking, alcohol drinking, and systemic diseases including systemic diseases, medication, oral health status, and stress. The question for dry mouth consisted of dryness in skin, eyes, lips, and nasal mucosa. The subjective dry mouth consisted of 6 questions measured by visual analogue scale(VAS). Cronbach's alpha was 0.881 in the study. Oral health related quality of life (OHIP-14) was adapted from Yoon. The questionnaire for OHIP-14 included functional limitation, physical pain, psychological disability, social disability, and experience in hadicap measured by Likert 5 scale. Cronbach's alpha was 0.885 in the study. Data was analyzed for a t-test, one-way ANOVA and multiple regression analysis by using SPSS(SPSS 18.0, USA) program. Results: There were positive correlations between oral health-related quality of life and self-reported dry mouth (functional limitation r=0.288, physical pain r=0.219, psychological discomfort r=0.193, physical disability r=0.280, psychological disability r=0.205, social disability r=0.224 and handicap r=0.270). In the multiple regression analysis, variation of self-reported dry mouth were positively associated with dry eyes{very often(${\beta}=0.305$)), sometimes(${\beta}=0.186$)}, dryness on lips{very often(${\beta}=0.247$), sometimes(${\beta}=0.177$)}, handicap(${\beta}=0.152$), physical disability(${\beta}=0.128$) and alcohol drinking(1-2 times/week)(${\beta}=0.116$) (p<0.001). Conclusions: Self-reported dry mouth may cause deterioration of the entire body dryness(dryness on eyes and lips), low oral health-related quality of life(handicap and physical disability) and alcohol drinking. Thus, It is necessary to develop oral health education programs to prevent and manage dry mouth in adults.

This study aims to understand causal relationship among preference factors - preferred design, design image, and design elements-to create interaction between artists and spectators, concerning eating and drinking table decoration which is produced with subjective representation chiefly by virtue of the authors' conceptualization and planning. As an experimental research , face-to-face personal interviews have been made in off-line setting through questionnaires. Acquired information from it has been analyzed, which results are as follows. As harmonious, warm, womanish design image, combination of pink-tone similar colors were preferred. As image adjectives highly related with design preference were 'harmonious and inharmonious' A design factor of 'harmonious' was combination of similar colors, while that of 'inharmonious' was association of mixed colors. It has been found that 'colors' have been an important factor among preference design factors. As above, a new concept for design can be established by using data-based information, along with suggesting a direction for preferred design in the field of eating and drinking table decoration. Furthermore, it will be possible to make a study of new preferred design through evaluation of quantitative spectators in this area. It is expected that such researches could give an opportunity to get satisfactory results from newly experimented designs using quantitative data even in a creative design area, as well as table decoration.

This study was performed in order to examine the effects of one to one interactive picture book reading on infants' reading response and teachers' language teaching efficacy. A total of 50 2-year-olds from 8 child care centers in Incheon were divided into an experimental group and a control group. The interactive picture book reading activities were carried out once a week during 12 weeks. The infants in the experimental group read one-to-one with teachers, and their counterparts read the same book in a group. The change in teachers' language teaching efficacy was examined, and their subjective perception was evaluated through in-depth interview. As a result of this research, the infants in the experimental group showed significantly increased verbal response, compared to the control group, both in the total score and most sub-factors such as naming, responding, asking, demanding, spontaneous utterance, and decontextualized utterance. They also represented a significant rise, compared to the control group, in the total score of non-verbal response and factors like finger indicating, imitating, and accepting. Finally, the teachers who led the experimental group showed increased language teaching efficacy, and evaluated the effects of interactive picture book reading with infants very positively.
