Objective: The purpose of this study was to identify factors associated with subjective memory impairment in patients with diabetes mellitus in a metropolitan city. Methods: The subjects of this study were 351 patients with diabetes mellitus aged 50 and over from five districts of Gwangju who participated in the 2018 Community Health Survey. We analyzed general characteristics, health-related behaviors and health related conditions and subjective experience of memory impairment. To find factors associated with subjective memory impairment, the chi-square test and multiple logistic regression analysis were used. Results: Of all subjects, 31.3% was reported subjective experience of memory impairment. The odds ratios (ORs; 95% confidence interval (CI)) for subjective memory impairment according to age were statistically significant at 1.9 (0.9-4.3) in patients in 60s and 2.2 (1.1-4.7) in patients in beyond 70s compared to those in 50s. The OR (95% CI) of ex-smoker compared to the non-smoker was 0.3 (0.8-0.9). The OR (95% CI) of depressive symptom compared to no depressive symptoms was 4.9 (95% CI: 1.8-13.7). Conclusion: In this study, subjective memory impairment in patients with diabets mellitus was associated with age, smoking, and depressive symptoms. Based on the results of this study, subjective memory impairment should be detected early through periodic cognitive function evaluation for elderly patients with diabetes mellitus, and a program for healthy cognitive function should be included in diabetes management program.

Purpose : This study examined the relationship between oral health management behavior and subjective health perception by using a tool that measures health-related quality of life named EQ-5D. The findings are expected to provide fundamental data for developing diverse programs, including health- and oral-health-related educational media, to ultimately enhance people's health-related quality of life. Methods : Adults over the age of 20 were extracted from the raw materials of the 8th national health and nutrition examination survey conducted in 2019. Among them, 4034 were finally chosen as the study subjects after checking the response distribution of relevant questions and excluding inadequate samples. Variables included general characteristics, health management behavior, oral health management behavior, subjective health perception, and EQ-5D level. Cross-tabulation test, independent t-test, one-way analysis of variance, and linear regression analysis were conducted using SPSS 25.0. Results : EQ-5D, which measures the level of health-related quality of life, was high when the subjects had a medical check-up experience, no experience of unsatisfactory medical service, and did not get an influenza vaccination (p<.001). The quality of life was higher when the subjects received dental inspections, did not require treatment, and used oral care goods (p<.005). Health-related quality of life was also higher when the subjective health level and subjective oral health level were high. Conclusion : Results indicate that subjective health, oral health perception level, and quality of life together were high when people had a regular check-up, did not neglect treatment, and used oral care goods. Considering the findings of this study, check-up programs that are customized for each age group are necessary. Health-related quality of life could be enhanced through the provision of diverse medical services and active efforts to prevent any medical blind spot.

Physical variables related to the subjective evaluation of wear comfort were explored. Experimental fabrics was those used in the previous paper where subjective sensations of women's thin shirts were reported. Fabrics include 100% cotton (unfinished), 100% cotton (water repellent finished), cotton/polyester 35/65 (unfinished), cotton/polyester 35/65 (peach skin finished), 100% polyester fabric(plain), 100% polyester crepe. Among various physical properties of the experimental fabrics, heat 8E moisture transport properties and surface properties were chosen as important variables based on the regression coefficient. Especially, humidity at the microclimate in dynamic mode was highly correlated to the subjective evaluation and appeared to be a sensitive physical predictor, compared to dry thermal transmission rate or water vapor transmission rate. Surface characteristic parameters, however, did not show consistant trend in the prediction of the human's subjective sensation. Interaction between surface properties and humidity measurement was also observed.

Using the first wave of KLoSA(Korean Longitudinal Study of Ageing) beta version, this study analyzed factors affecting early retired men's subjective life satisfaction through Binary Logit and Multiple Regression. Total 552 men were selected as a sample. The main results of empirical analysis in this study were as follows: The retirement reason(health-) and monthly household income(+) affected whether they were satisfied with the retirement life or not and subjective life satisfaction over all. Especially, the retirement reason(health-) had a stronger effect on whether early retired min were satisfied with the retirement life or not and their subjective life satisfaction than monthly household income revealed significant variable in previous studies. This result represents that the retiree's life satisfaction analysis model must include retiree's characteristics at the time of retirement as well as retiree's current status characteristics or socio-economic characteristics.

The main purpose of this study was to investigate the relationship between financial management behavior and subjective level of consumption of rural households. In this study, financial management behavior was defined to include 'budgeting' and 'expenditure management'. Data were collected from the 215 rural households in 13 different provinces of Chungnam, and 203 households were used for the analysis. Frequency distribution, means, and path analysis were employed for the statistical analysis. Major findings were as follows. Budgeting behavior had a significant positive effect on rural households' subjective level of consumption, while expenditure management behavior didn't have any significant effect. This implies that active and systematic financial management behavior such as budgeting is more effective than relatively passive financial management behavior like expenditure management on the enhancement of economic well-being of rural households. Age, education, and number of non-farm earners had indirect effects on the subjective level of consumption through budgeting behavior. Income stability had a direct effect and income had both direct and indirect effects on the subjective level of consumption.

The present study the feasibility of the new subjective assessment devise; Real-Time Subjective Assessment Digitizer (RTSAD). The subjects were instructed to evaluate their sensibility during the presentation of the positive and the negative visual stimuli using RTSAD. After the presentation of each of the stimulus, a questionnaire was used for comparing the results with those from RTSAD. It was argued that the biggest utility of the RTSAD is the capability of measuring and figuring out the trends of the subjective assessment in real time. The results from the questionnaires unlike the results from RTSAD, reflects only the averaged human sensibility for the entire time of the presentation of the stimulus.
