The purpose of this study was to apply a scientific and systematic method for assessing fashion goods' TV ads effects by EEG and questionnaires as determined by the type of ads appeal. Ads stimulants used in the survey were limited to underwear and sportswear that were advertised during $2000{\sim}2002$ on TV: 4 information-transferring and 4 emotion-evoking ads were used. Subjects were thirty healthy male and female college students. EEG was extracted from six lobes and the recorded EEG was analyzed by the range of frequency of ${\theta},\;{\alpha}\;and\;{\beta}$ waves. Data were analyzed by SPSS 11.0 with reliability test, $x^2$-analysis, t-test and frequency analysis. The emotion-evoking ads showed higher scores in memory, recall and attitude towards the ads. The responses of ${\theta}\;and\;{\alpha}$ wave were active throughout the ads but the response of ${\beta}$ wave was not. The results by the survey and the EEG test showed high similarities, indicating the EEG tests could be used as the supplementary tool for measuring ads effects.

Objectives: The purpose of the study is to investigate the oral health-related quality of life (OHIP-14) according to smoking in the male workers in Gunsan. Methods: A self-reported questionnaire was completed by 460 male workers in Gunsan from April 13 to 30, 2015. Among 460 workers, smokers were 205 and nonsmokers were 255. The questionnaire included three questions of general characteristics of the subjects, four questions of subjective oral health, fourteen questions of OHIP, ten questions of sobriety test (AUDIT), and eight questions of smoking (Fagerstrom Test for Nicotine Dependence, FTND). Data were analyzed by frequency analysis, t-test, ANOVA, Pearson's correlation, and multiple regression analysis using IBM SPSS(Statistical Package for the Social Science) for Windows 20.0 program. Results: In the nonsmokers, there was a negative correlation between the alcohol consumption, dental health condition, tooth pain, gum bleeding, and halitosis. The higher OHIP in the smokers had the negative correlation with nicotine dependence, alcohol consumption, tooth pain, gum bleeding, and halitosis. In order to improve OHIP, smokers are encouraged to manage gum bleeding, and non-smokers to halitosis. Conclusions: In order to improve OHIP, cessation of smoking and alcohol consumption is very important and it can lead to improve the quality of life in the workers.

The Purpose of this study was to investigate the relationship between materialism and clothing buying behavior (clothing shopping orientation, clothing selection standards, use of information sources, store selection standards, purchase and purchase intention of imported clothing). The data were obtained from questionnaires completed by 400 women in the Taegu area whose age was 20 years and older. The SPSS/PC$^{+}$ package was used for data analysis which included a test of reliability, frequency, percentage, factor analysis, t-test, and x$^2$ test. There were significant differences in clothing buying behavior between groups who had a higher tendency and a lower tendency toward materialism. In other words, those who had a higher tendency toward materialism enjoyed their shopping and pursued the world-known brands, imported brands, the latest fashions, and conspicious consumption more than those who had a lower tendency of materialism. The former put a greater focus on the latest fashion styles, brand image, and design then the latter when the\ulcorner bought clothing. Those who had a higher tendency toward materialism utilized more information sources than those who had a lower tendency. The former made purchases from the stores where they stock famous world-known brands and well-advertised stores, and had a greater purchase intention of imported clothing than the latter. In the purchase of imported clothing there was no significant difference between two groups.s.

The tubed steel reinforced concrete (SRC) column is a composite column in which the outer steel tube is mainly used to provide confinement on the core concrete. This paper presents experimental and analytical studies on the behavior of circular tubed SRC (TSRC) columns subjected to axial compression. Eight circular TSRC columns were tested to investigate the effects of length-to-diameter ratio (L/D) of the specimens, diameter-to-thickness ratio (D/t) of the steel tubes, and use of stud shear connectors on the steel sections. Elastic-plastic analysis on the steel tubes was used to investigate the mechanism of confinement on the core concrete. The test results indicated that the tube confinement increased the strength and deformation capacity for both short and slender columns, and the effects on strength were more pronounced for short columns. A nonlinear finite element (FE) model was developed using ABAQUS, in which the nonlinear material behavior and initial geometric imperfection were included. Good agreement was achieved between the predicted results using the FE model and the test results. The test and FE results were compared with the predicted strengths calculated by Eurocode 4 and the AISC Standard. Based on the analytical results, a new design method for this composite column was proposed.

Purpose: The aim of this study was to evaluate the nutritional status and to identify factors affecting malnutrition in hemodialysis patients. Methods: Data were collected from a convenience sample of 125 hemodialysis patients who agreed to participate in the study, between August 1 and October 4, 2014. Five structured questionnaires were used: Patient-generated Subjective Global Assessment, Simplified Nutritional Appetite Questionnaire, Self-rating Depression Scale, Fatigue Scale, and Family Support Scale. Data were analyzed by descriptive statistics, t-test, Mann-Whitney U test, ${\chi}^2$-test, and stepwise multiple regression analysis by using SPSS/WIN 22.0 program. Results: Of 125 patients, 30.4% were found to be malnourished. Malnutrition was related to age, family household income, depression, fatigue, social support, appetite, and levels of C-reactive protein and serum albumin. Stepwise multiple regression analysis showed that appetite, C-reactive protein level, fatigue, and albumin level were significant factors affecting malnutrition in hemodialysis patients. Conclusion: Regular and consistent nutritional assessment is essential in hemodialysis patients. Nurses who care for hemodialysis patients need to consider the factors identified from these findings when assessing their patients' nutritional status and needs.

The purpose of this study was to explore the effect of maternal perception of children's temperament on parenting stress. The subjects of this study were 303 mothers of four to six-year-old. Evaluations of Parent and Teacher temperament questionnaire for Children 3-7 years of age(Tomas, Chess, & Kom, 1977)(korean version) was used to measure children's temperament, and PDH(Parenting Daily Hassles) was used to measure maternal perception of parenting stress. Data were analyzed by descriptive analysis, t-test, ANOVA, Peasons's Correlation and multiple regression analysis and Duncan test for post test by SPSS WIN program. The results of this study were as follows; First, the average level of maternal perception of children's temperament was the highest in the category of adaptability and the lowest in the category of threshold of responsiveness. Second, maternal perception of children's temperament was significantly different according to children's sex. Boys were perceived higher than girls for the category of activity level. Third, the degree of daily hassles was explained by adaptability, the quality of mood, and activity level relatively, while the intensity of parenting stress could be predicted orderly by adaptability, threshold of responsiveness, attention span & persistence, regularity, and activity level. Fourth, mother's daily hassles was explained 22% valiance by children's temperament such as adaptability, the quality of mood, and activity level. Future research should be done to identify the interaction of temperamental factors.

Purpose: This study was conducted to test the reliability and validity of Family Burden Questionnaire. Method: The subjects were 156 caregivers of children with acute or chronic disease. To test the reliability, internal consistency using Cronbach's α coefficient was analyzed, and factor analysis, known-group technique, and concurrent validity were utilized for validity test. Result: Cronbach's α coefficient of the tool was .89. Six factors were identified and explained 58.7% of the total variance. Through analysis using known-group technique, the difference of family burden between acute and chronic disease groups was statistically significant(t= -4.09, p<.001). Correlations with mood state, other family burden score by Family Burden Interview Schedule, quality of life, and health symptoms were also relatively high and statistically significant. Conclusion: Family Burden Questionnaire showed a relatively high validity and reliability to measure the burden of caregivers caring patients with various chronic conditions in Korea. For the further study, it may be reconsidered to identify the factor structure of the Family Burden Questionnaire with the various subjects from different age groups.
