Objectives: The purpose of the study was to investigate the influencing factors of oral health-related quality of life in social workers. Methods: A self-reported questionnaire was completed by 240 social workers in Gwangju by convenience sampling method. The questionnaire consisted of general characteristics of the subjects(age, monthly salary, smoking, alcohol consumption) and systemic health condition(systemic diseases, medication, oral health status, and stress). The factors associated with oral health-related quality of life included skin dryness, eye dryness, lip dryness, and nasal dryness. The subjective dry mouth consisted of 6 questions measured by visual analogue scale(VAS). Cronbach's alpha was 0.868 in the study. The data were analyzed for t-test, one-way ANOVA and multiple regression analysis using SPSS 18.0 program. Results: The oral health-related quality of life in social workers varied by age, oral health status, stress status, and halitosis. The oral health-related quality of life had positive correlations with the subjective perception of dry mouth and whole body dry symptoms. The health status(${\beta}=-0.410$) had the influence on the oral health-related quality of life, nasal dryness(${\beta}=0.230$), age(${\beta}=0.189$), and halitosis (${\beta}=0.162) in order. Conclusions: The oral health-related quality of life was closely related to the health status and nasal dryness. It is necessary to develop the quality of life improvement programs including oral health prevention and care program in the social workers.

In this paper, we propose a blind audio watermarking using the tonal characteristic. First, we explain the perceptional effect of tonal on the existed researches and shout the experimental result that tonal characteristic is more stable than other characteristics used in previous watermarking studies against several signal processing. On the base of the result, we propose the blind audio watermarking using the relation among the signals on the frequency domain which compose a tonal masker. To evaluate the sound quality of our watermarked audios, we used the SDG(Subjective Diff-Grades) and got the average SDG 0.27. This result says the watermarking using the perceptional effect of tonal is available from the viewpoint of non-perception. And we detected the watermark hits from the watermarked audios which were changed by several signal processing and the detection ratios with exception of the time shift processing were over 98%. About the time shift processing, we applied the new method that searched the most proper position on the time domain and then detected the watermark bits by the ratio of 90%.

The sense of touch has both objective and subjective characteristics. During hand evaluation of the fabrics. psycho physiological processes such as emotion and stimulation. On other site, the mode of touch (passive vs. active) is also capable to modulate somatosensory responses. I.e., suppress somatocensory perception during active electrocortical responses to passive and active touch of the textiles with different subjective emotional preference. The study was carried out on 36 female college students. Physiological signals were acquired by Grass and BIOPAC 100 systems with AcqKnowledge variables, namely heart rate (HR), respiratory sinus arrhythmia (RSA), pulse transit time (PTT), respiration rate (RSP) and skin conductance parameters (SCL, amplitude, risetime and number of SCRs) were analyzed for baseline and stimulation conditions. Analysis was manifested in a form of moderate HR acceleration. RSP increase, RSA decrease (lowered vagal tone), decreased PTT and increased electrodermal activity (increased SCL, several SCRs) that reflects general sympathetic activation. Parietal EEG effects (on contra-lateral side to stimulated hand)were featured by short-term alpha-blocking, slightly reduced theta, significantly increased delta and enhanced fast beta activity with few variations across stimuli. The main finding of the study was that most and least preferred textures exhibited significant differences in autonomic (HR, RSP, PTT, SCR, and at less extent in RSA and SCL) and electrocortical responses (delta, slow and fast alpha, fast beta relative power). These differences were recorded both in passive and active stimulation modes, thus demonstrating reproducibility of distinction between most and least emotionally preferred tactile stimuli, suggesting influence of psychological factors, such as emotional property of stimulus, on physiological outcome.

This study identifies the relation between recognition relatively deprivation and consumption patterns. The data used were the seventh Korea Welfare Panel Study (KOWEPS). The final sample of 1,597 households was selected based on several sampling steps standard weights suggested by KOWEPS were applied. The final sample was subdivided into household recognizing relatively deprivation (51.7%) and non-household recognizing relatively deprivation (48.3%) per level of subjective income and objective income. We derived six consumption patterns from the cluster analysis as per consumption ratio: transportation dominant consumption pattern, essential consumption pattern, other dominant consumption pattern, care attention consumption pattern, private transfer consumption pattern, and education dominant consumption pattern. The results of this study are as follows. The analysis of the determinants of recognizing relatively deprivation in regards to question one found that the household was likely to be relatively deprived when: the head of a household was older, a household had a dual income, children and more total assets then those assessed 1 year ago compared to household living conditions, result of comparing the consumption patterns difference between household recognizing relatively deprivation and non-household recognizing relatively deprivation indicated that household recognizing relatively deprivation was more likely to belong to the transportation dominant consumption pattern, other dominant consumption pattern, and private transfer consumption pattern. The multinomial logistic analysis conducted to understand the determinants affecting the consumption patterns of household recognizing relatively deprivation indicated differences in demographic characteristics, household-related variables, financial variables and perception of economic conditions.

The purpose of this study is to provide a basic data of clothing development that can improve the satisfaction of the body shape by examining the subjective evaluation and characteristics of each type. The types of body shape of middle-aged women were analyzed as four types: elasticity loss ladder type, flat rectangular type, thin reverse ladder type, and upper body obesity inverted triangle type. The elasticity loss ladder type was developed with the lower body, and it was analyzed that the legs size such as the thighs and claves were large, the abdomen was protruded, and especially the underbelly appeared. The flat rectangular type was the largest of the four types, and was the skinny type. The width was larger than the thickness of the body, and the difference between the hip circumference and the waist circumference was small, and it was classified into a flat rectangular shape. The thin reverse ladder type was the smallest of the four types, the upper body was developed, the back had weight, and the body was leaning forward. And the lower body and leg were poor and the abdomen was protruding. Finally, the upper body obesity inverted triangular was the highest type of BMI index among 4 types. All of subjects belong to the mild and middle obesity, and the second was the smallest but the most weighted type among 4 types. They had the fat body and big bust, the upper body was developed, and the lower body and legs were analyzed to be poor body shape. Based on the body shape of middle-aged women, it is necessary to develop designs and patterns that can cover the shortcomings of body shape.

The purpose of this study was to investigate the subjective evaluation and the characteristics of each type of maternal self-awareness. It was to provide the basic data necessary for the development of clothing that can improve the satisfaction of the body shape of pregnant women. This study was conducted with Q methodology, and was performed for pregnant women over 6 months. Analysis was done with QUANL program. The recognition types of body shape of pregnant women was analyzed as three types: thin limbs and central hemispherical abdominal body shape, under abdomen protruding body shape, and thick upper arm and central abdomen protruding body shape. The thin limbs and central hemispherical abdominal body shape were considered to be normal, with the lowest BMI index before pregnancy. And the limbs were thin and the other parts were not overweight, but recognized that only the belly came out. The under abdomen protruding body shape was overweight with the highest BMI index before pregnancy. In addition to the circumference of the chest and hips, the body was gaining weight and was perceived to have a belly drooping down. The thick upper arm and central abdomen protruding body shape recognized that the middle part of the abdomen protruded like the first type, but it was different from the first type because the upper arm was thickened. In the future study, it would be a meaningful study to compare and analyze the difference with the recognition body of this study through analyzing the actual body shape of pregnant women.
