Purpose: The aim of this study was to evaluate correlations between denture satisfaction and various factors related to patients' and wearing dentures. Materials and Methods: Total 43 edentulous patients were recalled and they were wearing complete dentures fabricated more than one year ago. For patients' subjective assessment, the questionnaire based on the various literatures was developed and applied to patients for data acquisition. In addition, correlations were evaluated between subjective assessment and denture satisfaction score. For statistical analysis, Spearman correlation coefficient, multiple regression analysis, Mann-whitney U test and Kruskal-Wallis test were used to found out what the most considerable factors to denture satisfaction score (P < 0.05). Results: Denture satisfaction score of maxilla was higher than mandible (P < 0.05). In functional aspects, maxillary denture were received a favorable evaluation. Especially fit and pain causing were highly correlated to satisfaction. Gender, age, using period, visiting times after manufacturing denture were unrelated to satisfaction. But previous experience was related to denture satisfaction. Conclusion: Denture satisfaction was determined by a combination of various factors related to patients.

Objective: From a review of published information on genetic association studies, a meta-analysis was conducted to determine the influence of the genes ${\kappa}-casein$ (CSN3) and ${\beta}-lactoglobulin$ (LGB) on milk yield traits in Holstein, Jersey, Brown Swiss, and Fleckvieh. Methods: The GLIMMIX procedure was used to analyze milk production and percentage of protein and fat in milk. Models included the main effects and all their possible two-way interactions; not estimable effects and non-significant (p>0.05) two-way interactions were dropped from the models. The three traits analyzed used Poisson distribution and a log link function and were determined with the Interactive Data Analysis of SAS software. Least square means and multiple mean comparisons were obtained and performed for significant main effects and their interactions (p<0.0255). Results: Interaction of breed by gene showed that Holstein and Fleckvieh were the breeds on which CSN3 ($6.01%{\pm}0.19%$ and $5.98%{\pm}0.22%$), and LGB ($6.02%{\pm}0.19%$ and $5.70%{\pm}0.22%$) have the greatest influence. Interaction of breed by genotype nested in the analyzed gene indicated that Holstein and Jersey showed greater influence of the CSN3 AA genotype, $6.04%{\pm}0.22%$ and $5.59%{\pm}0.31%$ than the other genotypes, while LGB AA genotype had the largest influence on the traits analyzed, $6.05%{\pm}0.20%$ and $5.60%{\pm}0.19%$, respectively. Furthermore, interaction of type of statistical model by genotype nested in the analyzed gene indicated that CSN3 and LGB genes had similar behavior, maintaining a difference of more than 7% across analyzed genotypes. These results could indicate that both Holstein and Jersey have had lower substitution allele effect in selection programs that include CSN3 and LGB genes than Brown Swiss and Fleckvieh. Conclusion: Breed determined which genotypes had the greatest association with analyzed traits. The mixed model based in Bayesian or Ridge Regression was the best alternative to analyze CSN3 and LGB gene effects on milk yield and protein and fat percentages.
This study intend to provide basic evidence needed to improve the life satisfaction of disabled children and youth by analyzing factors to influence on their life satisfaction. To accomplish this study's goal, raw data of Survey of Disabled People in 2014 conducted by the Ministry of Health and Welfare was utilized for multiple regression analysis to identify determining factors among family relation satisfaction, domestic violence, type of household, economical conditions, family relationship satisfaction, subjective health status, severity of disability, experience of discrimination, satisfaction on number of friends and school adjustment on 197 disabled children's life satisfaction. Results of the analysis are as follows. Domestic violence, family relationship satisfaction, subjective health status, and satisfaction on number of friends are influencing factors on life satisfaction of disabled children's and youth students. This results shows that strengthening family structure and function, expanding all family members participating program, implementing sociability improvement program and promoting health condition are needed to heighten the life satisfaction of students with disabilities.
New twenty 2-(n-octyl)-3-(n-propyl)isothiourea derivatives(S) were synthesized which is modified from the insecticidal Buprofezine (Applaud) in the selective insecticidal activities in-vitro against Diamond-Back moth (Plutella Xylostella Linnaeus). The structure activity relationships(SAR) between the insecticidal activity$(pI_{50})$ and a various physicochemical parameters of the substituent(Z) of S were analyzed by the multiple regression technique. The activities would depend largely on the MR, ${\pi}$ and $L_1$ parameters. The SAR was rationalized by parabolic function of MR, ${\pi}$ and $L_1$ constant, where the optimal values of the constants were $L_1=5.22{{\AA}}$, $MR=15.70\;Cm^3/mol$ and ${\pi}=1.60$, respectively. The steric effects play an important role in determining insecticidal activity. The SAR suggest that the S derivatives having a substituents with a small breadth and an appropriate length as Z group showed potent activity. From the results, the iso-propyl group(Z) substituent (5) with three carbon atom was the most effective compound.
Objectives: The purpose of this study was to find out the fear of dentist care, subjective recognition of dental health, and quality of life in the male high school students and to analyze the influencing factors on dental health care. Methods: A self-reported questionnaire was filled out by 243 special high-school in Deagu province from March 3 to March 14, 2014. The questionnaire consisted of general characteristics of the subjects(5 questions), subjective recognition of health and activities to improve health(6 questions), dental fear(20 questions), oral health related quality of life(16 questions). The instrument for dental fear was adapted from measured by Berggren Dental Fear Survey(DFS). A total of 20 DFS questions included treatment avoidance(8 questions), stimulus reaction(6 questions), and physiological reaction(5 questions) and score by Likert 5 scale. Cronbach alpha was 0.974 in the study. Oral health related quality of life was measured by 16 questions of CPQ11-14 for the adolescents by Lau. CPQ11-14 consisted of oral symptoms(4 questions), functional restriction(4 questions), and emotional wellbeing(4 questions). The instrument was score by Likert 5 scale and Cronbach alpha was 0.9354 in the study. Data were analyzed using SPSS 18.0 program for ANOVA and multiple regression analysis. Results: Fear of dentist care showed significant differences in treatment avoidance factor(p<0.001), stimulus reaction factor (p<0.05), and physiological reaction factor(p<0.001). The factors depended on subjective recognition of health and health-improving activities and differences in treatment avoidance factor(p<0.05) and physiological reaction factor(p<0.01). The dental symptoms factors showed significant differences in health recognition(p<0.001), interest in health(p<0.001), alcohol drinking status(p<0.001) and regular meal(p<0.001). While function limit factors showed differences in health recognition (p<0.001), interest in health(p<0.001), smoking(p<0.001), alcohol drinking(p<0.001) and regular meal(p<0.001). Mental and social stabilities factors showed significant differences in health recognition(p<0.001), interest in health(p<0.001) and alcohol drinking status(p<0.001). Among the factors influencing on the quality of life in dental health, interest in health(p<0.005), alcohol drinking(p<0.005) and physiological reaction in the midst of fear of dentist care(p<0.001) were the significant impact factor.

This study has an objective to analyze the causal relationship between the business resource of the members in the Airport Special Guard's firms and its effect on their business attitude and turnover intention. To carry out the study, I established a population of Airport Special Guard's working at the Airport firms in In-cheon, Kim-po, Cheong-ju and Dae-gu. Then a total of 300 questionnaires were sent out for the survey using the random sampling method of clusters. The study was carried out over about four months, from July, 2016 to october, 2016. A total of 260 questionnaires were used for the final data. 40 questionnaires were excluded either because they were not returned or contained extreme value. In this study, a statistical package of SPSS WIN 18.0 were used in the data analysis and the causal relationship was verified using the multiple regression analysis. The analysis showed the business resource to have a positive effect on the business attitude but a negative effect statistical level of p<.01 on the turnover intention at the statistical level of p<.001 and the hypothesis was adopted. The hypothesis regarding the business attitude was also adopted because business attitude was found to have a negative effect on the turnover intention at the statistical level of p<.01. In addition, business attitude was found to have a negative effect on the relationship between the business resource and turnover intention at the statistical level of p<.05. As a result, the hypothesis about the business attitude would function as the parameter was only partially adopted. Through these research result, it was investigated that the relation between business resource, business attitude and turnover intention is significantly effective variable in airport special guard's. Additionally, business resource is the most important.

The aim of this study is to define a correlation between spatial distribution characteristics of FFG(Functional Feeding Groups) of aquatic insects and related environmental factors in the Geum River based on the theory of RCC(River Continuum Concept). For that objective we had used SMRA(Stepwise Multiple Regression Analysis) method to analyze close relationship between the distribution of aquatic insects and the physical and chemical factors that may affect their inhabiting environment in the study area. And then, a probabilistic method named Frequency Ratio Model(FRM) and spatial analysis function of GIS were applied to produce a predictive distribution map of biota community considering their distribution characteristics according to the environmental factors as related variables. As a result of SMRA, the values of decision coefficient for factors of elevation, stream width, flow velocity, conductivity, temperature and percentage of sand showed higher than 0.5. Therefore these 6 environmental factors were considered as major factors that might affect the distribution characteristics of aquatic insects. Finally, we had calculated RMSE(Root Mean Square Error) between the predicted distribution map and prior survey database from other researches to verify the result of this study. The values of RMSE were calculated from 0.1892 to 0.4242 according to each FFG so we could find out a high reliability of this study. The results of this study might be used to develop a new estimation method for aquatic ecosystem with macro invertebrate community and also be used as preliminary data for conservation and restoration of stream habitats.
Statement of problem. Although a number of previous investigations have been carried out on the polymerization shrinkage-strain kinetics of provisional crown and fixed partial denture (FPD) materials, the effect of the changes of liquid monomer to powder ratio on its polymerization shrinkage-strain kinetics has not been reported. Purpose. The purpose of this study was to investigate the influence of liquid monomer to powder ratio of polymer-based provisional crown and FPD materials on the polymerization shrinkage-strain kinetics. Material and methods. Chemically activated acrylic provisional materials (Alike, Jet, Snap) were investigated. Each material was mixed with different liquid monomer to powder ratios by volume (1.0:3.0, 1.0:2.5, 1.0:2.0, 1.0:1.5, 1.0:1.0). Time dependent polymerization shrinkage- strain kinetics of all materials was measured by the bonded-disk method as a function of time at $23^{\circ}C$. Five recordings were taken for each ratio. The results were statistically analyzed using one-way ANOVA and the multiple comparison Scheffe test at the significance level of 0.05. Trends were also examined by linear regression. Results. At 5 minutes after mixing, the polymerization shrinkage-strains of all materials ranged from only 0.01% to 0.49%. At 10 minutes, the shrinkage-strain of Alike was the highest, 3.45% (liquid monomer to powder ratio=1.0:3.0). Jet and Snap were 2.69% (1.0:2.0) and 1.58% (1.0:3.0), respectively (P>0.05). Most shrinkage (94.3%-96.5%) occurred at 30 minutes after mixing for liquid monomer to powder ratio, ranging from 1.0:3.0 to 1.0:1.0. The highest polymerization shrinkage-strain values were observed for the liquid monomer to powder ratio of 1.0:3.0. At 120 minutes after mixing, the shrinkage-strain values were 4.67%, 4.18%, and 3.07% for Jet, Alike, and Snap, respectively. As the liquid monomer to powder ratio increased, the shrinkage-strain values tend to be decreased linearly (r=-0.769 for Alike, -0.717 for Jet, -0.435 for Snap, $r^2=0.592$ for Alike, 0.515 for Jet, 0.189 for Snap; P<0.05). Conclusion. The increase of the liquid monomer to powder ratio from 1.0:3.0 to 1.0:1.0 had a significant effect on the shrinkage-strain kinetics of polymer-based crown and FPD materials investigated. This increased the working time and decreased the shrinkage-strain during polymerization.
From March 1, 2016 to August 31, 2016, 375 dental implant patients between the ages of 30 and 70 years to evaluate their subjective symptoms and satisfaction according to prosthesis methods. The collected data were analyzed using the chi-square distribution test, t-test, one-way analysis of variance, and multiple logistic regression. Of the patients with subjective symptoms of peri-implantitis, 40.5% reported food impaction, 49.1% reported bleeding, 61.1% reported pain, 61.9% reported halitosis, and the overall satisfaction level with the implants was 3.95 points. In the prosthesis methods, implant-teeth connective group showed the lowest level of the food impaction (21.3%), the pain (35.5%), and the halitosis (36.6%) (p<0.001), and the lowest bleeding was the implant single (33.8%) (p<0.05). Patient satisfaction was higher in the implant-teeth connective group (4.06 points) and the group without bone grafting (4.03 points) (p<0.01). Factor analysis showed that implant satisfaction was 0.43 times lower in the single implant group and 0.44 times lower in the implant-implant connective group than in the implant-teeth connective group. As a result of the study, it is expected that the method of extending the life of adjacent teeth and restoring the function of the tooth defect region is an implant-teeth connection method, so that it can be utilized positively through various clinical studies.
