I investigated the situation of self-realization for oral malodor and real occurrence of it and researched the situation of coincidence by self-administrated questionnaire and real oral malodor of dental hygiene students in Kyeonggi province and Kyeongbuk province to use as a reference data on prevention and treatment of oral malodor. The obtained results were as follows: 1. Concerning the grade of the subjective symptom of oral odor, a little bit oral malodor was the highest by reaching 77.6%, and no oral malodor was 20%. 2. The time when one feels the oral malodor highest was revealed immediately after awakening from the sleep by running up to 88.2%. 3. Concerning the extent of aversion during the occurrence of oral malodor from other people, 57.6% expressed as unpleasant, and 3.5% showed no aversion. 4. Concerning the intention to participate in the prevention program against the oral malodor, 51.8% had intention of it. 5. Hydrogen sulfide 7.61V19.30, methyl mercaptan 9.53V67.90, dimethyl sulfide 58.31V121.37(pF0.05) marked as causing factors in the 132 respondents who answered that they had a little bit oral malodor in comparison with the grade of subjective symptom and the measurement of actual oral malodor. As the above-mentioned results were obtained by limited subjects, the more diversified and precise comparative study is considered to be needed through the classification of various levels of research subjects.

Recently, drivers have begun to regard comfort in the cabin as one of the most important factors in construction equipment like forklifts. Accordingly, it has become more important to design a forklift cabin with a better sound quality as well as lower sound level, which can make a driver more comfortable. In this paper, the correlation between subjective evaluation and Zwicker's sound quality index was analyzed through a blind test by a few workers in forklifts and other construction equipment in several countries. Correlation analysis showed that Loudness and Sharpness were ranked in sequence, and tendencies were different from country to country. Also, contribution analysis for Loudness and Sharpness using operational transfer path analysis (OTPA), which is widely used in the field of noise, vibration, and harshness (NVH), was performed. However, Loudness and Sharpness cannot be used with OTPA directly because there are no linear relationships between the sources and receivers. In this paper, both are calculated by applying the DIN 45631 method with a contribution rate (%) of 1/3 Octave Sound Pressure Level by OTPA method in addition to considering spectral masking.

Purpose: This study aimed to identify types of quality of life (QoL) based on the 5 dimensions of EQ-5D and predict factors affecting types of QoL. Methods: This study was a secondary analysis using data from the Korean Health Panel Survey-II(2012). Participants were 2,071 middle-aged men who had completed the additional survey in 2012 and the data were analyzed using SPSS 20.0 and Mplus 5.21 for latent analysis. Results: Three latent classes of QoL were identified: serious (2.4% of the sample), threatened (15.5%), and stable types (82.0%). The types and characteristics of QoL among the latent classes differed. On comparing latent type 1 with latent type 2, the socioeconomic status (p<.05), employment status (p<.05), and subjective health status (p<.001) were found to be significant. On comparing latent type 1 with latent type 3, the socioeconomic status (p<.05), current smoking status (p<.001), and subjective health status (p<.001) were found to be significant. On comparing latent type 2 with latent type 3, the socioeconomic status (p<.05), subjective health status (p<.001), stress (p<.001) were found to be significant. Conclusion: The results showed significant heterogeneity in types of QoL and the predictors of QoL by types were different. These findings provide basic information for developing nursing interventions to improve QoL. Specific characteristics depending on the subtypes should be considered during the development of interventions.

Purpose: This study was done to examine the effect on turnover intention (TI) of terminal care stress (TCS) on nurses working in long-term care hospitals (LCH). Methods: Participants were 182 nurses from 6 Seoul LCH. Data were collected from October to December, 2017. Self-report questionnaires were used to collect data on general characteristics, TCS, and TI. Results: Subjective satisfaction on the job (r=.52, p<.001), number of monthly terminal care elders (r=.16, p=.043), TCS (r=.16, p=.027), and sub-categories of TCS, 'difficulty for assigning timetable to care for terminally ill patients' (r=.17, p=.025), 'feeling a burden of caring for terminally ill patients' (r=.23, p=.002), and 'conflict with terminally patients' (r=.16, p=.034) showed statistically significant correlation with TI. Multiple regression analysis showed significant influence of subjective satisfaction with job (${\beta}=.52$, p<.001) and TCS (${\beta}=.23$, p=.001) with a 30.3% explanatory power. When sub-categories of TCS were entered, subjective satisfaction with the job (${\beta}=.50$, p<.001) and 'feeling burden of terminally ill patients' (${\beta}=.28$, p<.001) were factors significantly influencing TI with explanatory power of 32.8%. Conclusion: Findings of this study suggest that it is needed to develop standardized practice guidelines and educational programs for terminal care in LCH as well as stress healing programs for nurses.

Objectives: The purpose of this study was to investigate how mental health status affects oral health in the elderly. Methods: The subjects of the study provided the data for the sixth Korea National Health and Nutrition Examination Survey from 2013 to 2015. Four-hundred and twenty-one subjects were selected for the study. All data were analyzed by complex sampling frequency, chi-square test, and composite multiple regression analysis using SPSS 21.0 version. In addition, a significance level of 0.05 was considered. Results: The general factors affecting cases of periodontal disease were general characteristics, mental health status, oral health status, elderly males, household income, education level, daily brushing frequency, speaking, and stress. The effect of periodontal disease was 1.64 times higher in the male group than in the female group (p<0.001). In the household income level, the 'low' group had 1.91 times more periodontal disease, while the 'mid low' group had 1.64 times more periodontal disease than the 'high' group (p<0.05). Periodontal disease was found to be lower in the group that recognized subjective oral health status as 'good' (p<0.05). The study subjects had low levels of periodontal disease when there was no speaking difficulty (p<0.05). Conclusions: Therefore, in order to improve oral health of the elderly, it is necessary to understand the mental health condition of the elderly and prepare proper oral health education programs accordingly. Institutional devices for various oral health projects should be prepared, as well.
