Purpose: The purpose of this study was to identify relationships of periodontal disease and health related quality of life (HRQoL) in pregnant women. Methods: The participants in this study were 129 pregnant women. Data were collected using questionnaires of characteristics of the participants and subjective perception of periodontal disease and a dentist's assessment of periodontal disease. Data were analyzed using descriptive statistics, correlation, and hierarchical multiple regression. Results: The physical QoL showed significant negative correlation with subjective perception of periodontal disease (r=-.21, p=.013). Mental QoL had significant negative correlations with subjective perception of periodontal disease (r=-.32, p<.001) and objective periodontal disease (r=-.34, p<.001). Hierarchical multiple regression analyses revealed that pregnant women who had a history of abortion and had higher subjective perception of periodontal disease tended to report lower levels of physical QoL. Pregnant women whose age are between 30-34 years and higher subjective perception and objective periodontal disease tended to report lower mental QoL. Conclusion: To improve HRQoL of pregnant women, nurses should pay attention on the status of periodontal disease. Careful assessment of oral healthy behaviors and proper intervention for oral health of pregnant women are needed to enhance HRQoL of pregnant women.

This study was cross sectional descriptive survey study to analysis effect of health perception and mental health status on the quality of life in the late middle aged people (45-65 years old). The data for the study were collected online from November 20 to December 10, 2019, from those who agreed to participate in the study voluntarily. A total of 192 data were used for the study. This study analyzed the Pearson correlation analysis, Descriptive analysis and Regression analysis using SPSS 18.0. As a result, the participants were 41.7% male and 58.3% female. The age group was 45-50 years old 4.2%, 51-55 years old 20.8%, 56-60 years old 54.1% and 61-65% 20.8%. Mental health status was associated with physical QOL(r=-347, p<0.01), Psychological QOL(r=-.439, p<0.01), and Social QOL(r=.280, p<0.01). Subjective health perception was associated with physical QOL(r=-589, p<0.01), Psychological QOL(r=.222, p<0.01), and Social QOL(r=.286, p<0.01). subjective health perception was found to affect all sub-factors except environmental quality of life under the statistical significance (p<0.01).

This study can be helpful in establishing and establishing company-wide marketing strategies from the supplier's point of view by analyzing the effects of rental service users' risk perception and service quality on customers' re-use intentions, and revealing differences according to demographic characteristics. It was intended to provide valid results. A total of 218 data were used as analysis data. Frequency, factor, mean, reliability and regression analysis, ANOVA, and t-test were performed through SPSS program (statistics). As a result of the study, first, as a result of analyzing the effect of risk perception on rental service quality, functional and psychological risks have a negative (-) effect on service quality. Second, in the relationship between service quality and re-use intention, the empathy factor has a high positive (+) effect, and as a result of analyzing the effect of risk perception on re-use intention, functional and psychological risk have the greatest influence, and financial Risk perception was also highly influential. In conclusion, the research results suggest that increasing the concentration of marketing strategies by reducing the negative (-) effect related to risk perception for short-term customers and housewives and enhancing the reliability and empathy for service quality can maximize the sales of suppliers.

Objective: Improvements in diet can decrease the cancer rates. The aim of the present study was to determine the relationships between self-perception of diet quality and personality, impulsiveness, stress, coping strategy, sense of coherence, self-efficacy, and social support. Methods: This cross-sectional study was conducted using a multiple-stratified random sampling method based on the Korea Census of 2007. In October 2009, investigators conducted 15-minute face-to-face interviews with 1,530 South Korean volunteers who ranged from 30 to 69 years of age without a history of cancer. Results: Respondents were more likely to perceive that they consumed a healthy diet if they were older than 50 years, lived with a partner, had a monthly family income greater than $4,000 USD, had a low perceived risk of cancer, consumed less alcohol, exercised regularly, had a less agreeable or conscientious personality, had low stress levels, had a high sense of coherence or self-efficacy, and had ample social support. Conclusion: Psychosocial factors, such as personality, stress, sense of coherence, self-efficacy, and social support, are associated with the self-perception of diet quality. Analysis of the factors that contribute to a perceived healthy diet could assist with the design of educational campaigns.

This study was intended to investigate the influences that consumer's price sensitivity, bundle discount type, and price level of the male cosmetics have on consumer attitude. The design of this research was comprised of $2{\times}2{\times}2$ mixed design studies. The first element was high price sensitivity vs. low sensitivity, the second element was the bundle discount type (mixed leader vs. mixed-joint), and the third element was the price level of male cosmetics (high-price brand vs. low-price brand). The results of this study showed that price sensitivity, bundle discount type and price level of male cosmetic had a statistically significant interaction effect on the consumer's quality perception. The quality perception of low-cost brands for high price sensitivity/mixed-joint bundle group was low. The quality perception of low-cost brands for mixed-leader bundled groups did not change significantly even when the price sensitivity became higher. However, it can be seen as the same result that the overall value is higher when suggested the price information in Mixed-leader bundle than Mixed-joint bundle. In particular, this study suggests that price information should be presented in mixed-leader bundles for high price sensitivity and low cast brands.

This paper discusses how to effectively guarantee the coverage and connectivity quality of wireless sensor networks when joint perception model is used for the nodes whose communication ranges are multi-level adjustable in the absence of position information. A Connect Coverage Algorithm Based on Joint Sensing model (CCAJS) is proposed, with which least working nodes are chosen based on probability model ensuring the coverage quality of the network. The algorithm can balance the position distribution of selected working nodes as far as possible, as well as reduce the overall energy consumption of the whole network. The simulation results show that, less working nodes are needed to ensure the coverage quality of networks using joint perception model than using the binary perception model. CCAJS can not only satisfy expected coverage quality and connectivity, but also decrease the energy consumption, thereby prolonging the network lifetime.
