This study investigates the factors influencing quality of life for cancer patients based on demographic characteristics, physical-mental health, and oral health. These factors are analyzed using the results from 235 cancer patients in Korea's 7th national health and nutrition survey. Data were analyzed using PASW Statistics Ver. 18.0. Studies show that cancer patients experienced stress (74.5%), depression (84.3%), and activity limitations (15.3%). In oral health, problems chewing were often experienced in groups with low incomes (3.35±.21), activity limitations (2.71±.31), and depression (3.01±.27). The factors influencing quality of life were higher by 3.43 times in the low-income group and by 8.39 times in the activity-restricted group, by 2.74 times in the high-stress group, by 4.58 times in the depression group, by 2.68 times in the chewing-problems group, and were 4.92 times higher in the speech problems group (p<0.05). To improve quality of life, not only mental and physical health care, but also oral care is necessary. An integrated management plan for medical staff in the treatment process of cancer patients is required to prevent mental, physical, and oral discomfort.

Purpose: The aim of this study was to compare the levels of anxiety, depression, and quality of life (QOL) among kidney or liver transplant candidates and recipients. Methods: A cross-sectional descriptive design was utilized. The 160 subjects were recruited and assigned to three different conditions: awaiting transplant group; post-transplantation (TPL) group within less than one year of surgery; and post-TPL group with one year and no more than two years post surgery. The levels of anxiety and depression were measured by the Hospital Anxiety and Depression Scale. The level of quality of life was measured by the Medical Outcomes Study Short Form-36 version 2. Results: The anxiety score was significantly higher in the waiting group compared with the 1~2 years post TPL group. The depression score was significantly higher in the waiting group compared with the post TPL groups. The QOL was significantly lower in the waiting group compared with the post TPL groups. Conclusion: Our results show a high prevalence of anxiety and depression and a marked reduction in the QOL in transplant candidates compared to the recipients. This study indicates that the group waiting for transplants may have unmet needs during that time period. Health professionals should be encouraged to attend to the psychological distress of the transplant candidates in order to improve their quality of life.

This study aimed to compare the effects of applying different types of dentin bonding agents (DBAs) on tooth and on the sealing ability of CSC in regenerative endodontic procedures (REPs). Specimens were made from 120 human first premolars and categorized into the following groups based on the presence and the type of DBA: Group I, no bonding; Group II, One-Step; Group III, Clearfil SE Bond; and Group IV, Single Bond Universal. Subsequently, the groups were categorized into Subgroup a and Subgroup b, in which Endocem MTA^® Premixed Regular and Biodentine were used, respectively. The CIE L^*a^*b^* on the photos taken prior to TAP placement (S0), 1 week after TAP placement (S1), 2 weeks after TAP placement (S2), 4 weeks after TAP placement (S3) and 2 weeks after CSC placement (S4) was used to assess discoloration. The samples were submerged in a 2% methylene blue solution and magnified by 30 times under a stereomicroscope to assess microleakage. The application of DBA during REP reduced crown discoloration, while Biodentine showed minimal discoloration with or without DBA and regardless of the DBA type. Additionally, the application of DBA did not increase microleakage.

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.

The safety speed 5030 policy, which is currently being implemented nationwide, tends to increase citizens' dissatisfaction due to reduced mobility and inconvenience. In order to successfully promote the Safety Speed 5030 policy, it is important to collect various opinions of citizens who use roads by deviating from quantitative policy evaluation criteria such as traffic accidents and traffic speed. Therefore, in this study, citizens who use roads were classified into a driver group and a non-driver group, and civic consciousness analysis such as adequacy evaluation of speed limit, satisfaction evaluation of road service quality (MDS), and importance-satisfaction analysis (IPA) was conducted. As a result of the analysis of civic consciousness, in particular, satisfaction with mobility, economy, and environment was low. Accordingly, it was intended to promote the successful implementation of the Safety Speed 5030 policy by presenting measures to improve the speed limit and quality of road service for roads with low satisfaction.

In literature, empirical studies investigating how stress affects HRQOL (health related quality of life) through physical activities are insufficient. In this sense, on the basis of KNHANES dataset for 2008 ~ 2013, we conducted an empirical study. Empirical results revealed that in the male group with stress experience, HRQOL was significantly influenced by age, household income, education, occupation, physical activity level. To do so, we adapt the chi-square analysis and the logistic regression analysis. Meanwhile, in the stress non-experience group, the low level activity has lower HRQOL than the high level activity(male: OR=1.15 p<0.001, female: OR=1.18 p<0.001). In the stress experience group, the male has the same pattern of effect compared to the stress non-experience group(OR=1.79 p<0.01). However, in the female, the low level activity has the higher HRQOL than the high level activity(OR=1.18 p<0.05). Therefore, we confirmed that physical activity has a different effect on HRQOL through stress experience.

To test the shear bond strength of a new "one-bottle adhesive" system to primary dentin two commercially available one-bottle adhesives (Prime & Bond NT, Single bond) and conventional three step system(Scotchbond Multi-Purpose Plus) were included for comparison. And We observe the interfacial morphology by scanning electron microscope. 90 primary molar teeth were embedded in acrylic and buccal and lingual surface were polished to 320 grit to create standardized dentin surface for testing. After bonding of composite resin to sample surfaces according to the manufacturer s direction and 1000 times thermocycling in dwell time 30 second, Shear bond strengths of adhesives to dentin were determined using universal testing machine and analyzed by ANOVA test. Another groups of specimens were treated by hydrochloric acid to secure the resin only and those tags were evaluated under SEM for their length and forms and the morphology of the bonding sites were also observed. The result are as follows. 1. Group I(Prime & Bond NT) showed higher shear bond strength than group iI(Single Bond) and III(Scotchbond Multi Purpose Plus) but no statistically significant difference was founded between groups(p>.05). 2. Relating long resin tags of $70-120{\mu}m$ were observed in samples of all groups under SEM. We could observed hybrid layer, resin tag and many lateral branches in every group. But, we observed in group III rare lateral branched than other two group and discontinuous hybrid layer.

The effect of chronic ethanol consumption on the concentration of minerals in tissues and serum was studied in growing broiler chicks. Four different groups of the chicks were fed mixtures of 0(control), 1,2 and 3% ethanol and water respectively for 7 weeks. Body weight gain in 1% ethanol group and liver weight in 3% ethanol group were significantly higher than those of control. Mg, K, Mn, and Zn concentrations in liver were higher in ethanol groups than those in control. In ethanol groups, femoral muscle Mg level was increased while its Na concentration was decreased. The concentrations of Ca, Mg and Na in serum were higher in 3% ethanol group than those in control, 1 or 2% ethanol groups. In femur, Zn and Fe levels in 1% ethanol group and Mn concentration in 2 or 3% ethanol groups were increased. But its weight, length, and ash content were not affected by ethanol intake.

The purpose of this study was to evaluate the effect of various acid treatments on dentin bonding. Freshly extracted human teeth were uprightly embedded in self curing acrylic resin, and their occlusal surfaces were grinded to expose flat dentin surfaces. The specimens were divided into 4 groups. Specimens of one group were not treated so as to be a control and those of the other three groups were threated with 10% polyacrylic acid, 10% phosphoric acid, and 10-3 solution(10% citric acid/3% ferric chloride) respectively. Primer, bonding resin and composite resin were applied over the treated dentin surfaces sequentially. All specimens were stored in $37^{\circ}C$ distilled water for 24 hours, then the tensile bond strength was measured and the treated dentin surfaces and fracured dentin surfaces were examined under a scanning electron microscope. The results were as follows: Bond strengths of acid-treated groups were higher than those of the untreated group. In the acid-treated groups, bond strength was found to be the highest in the 10-3 solution group followed by the 10% phosphoric acid group and the 10% polyacrylic acid group(P<0.01). On SEM examination of dentin surfaces, the untreated dentin surface showed a remaining smear layer and closed dentinal tubules. Dentin surfaces treated with 10 % polyacrylic acid showed a clean dentin surface without the smear layer, but showed remaining smear plugs in dentinal tubules. A dentin surface treated with 10% phosphoric acid or 10-3 solution showed open dentinal tubules without the smear layer or smear plugs. On SEM observation of the fractured dentin-resin interface, the untreated group showed that failure occurred in the smear layer. The group treated with 10% polyacrylic acid showed no resin tag remained in the dentinal tubules, but resin tags in the dentinal tubules were observed in the group treated with the 10% phosphoric acid or the 10-3 solution. On the failure mode examination, the higher the bond strength of the group, the higher the frequency of cohesive failure. The coefficient between bond strength and cohesive failure rate was 0.71.
