This study investigated the relation of androgynous parent's child-rearing practices to children's self-perceived competence by comparison of the effectiveness of androgynous people as parents compared with parents who are other-typed in their sex-role identity. The subjects were 362 third and sixth grade children and their parents selected from two elementary schools in Seoul. The instruments were a children's self-perceived competence scale, a perception of maternal warmth and control scale, a perception of paternal warmth and control scale, parent's self-esteem scale, and parent's sex-role identity scale. Frequencies, percentiles, mean, ${\chi}^2$ test, two way-ANOVA, one way-ANOVA, Cronbach's ${\alpha}$ and $Scheff{\acute{e}}$-test were used for data-analysis. The major findings showed that (1) Androgynous and masculine fathers had higher self-esteem than feminine or undifferentiated fathers. Androgynous, masculine, and feminine mothers had higher self-esteem than undifferentiated mothers. (2) There was no difference in children's perception of parental warmth and control as related to parent's sex-role identity. Androgynyous parents were not more likely to be authoritative parents. (3) Sons of androgynous parents had higher self-perceived competence than those of sex-typed parents, while daughters of sex-typed parents had higher self-perceived competence than those of androgynous parents.

The focus of this study was to investigate whether there is a position effect on identification accuracy of L2 consonants by Korean listeners and to examine how Korean listeners perceive the phonetic properties of initial and final consonants produced by a Korean learner of English and an English native speaker. Most studies examining L2 learners' perception of L2 sounds have focused on the segmental level but very few studies have examined the role of prosodic position in L2 learners' perception. In the present study, an identification test was conducted for English consonants /p, t, k, f, ɵ, s, ʃ/ in CVC prosodic structures. The results revealed that Korean listeners identified syllable-initial consonants more accurately than syllable-final consonants. The perceptual accuracy in syllable initial consonants may be attributable to the enhanced phonetic properties in the initial consonants. A significant correlation was found between error rates and F2 onset/offset for stops and fricatives, and between perceptual accuracy and RMS burst energy for stops. However, the identification error patterns were found to be different across consonant types and between the different language speakers. In the final position, Korean listeners had difficulty in identifying /p/, /f/, /ɵ/, and /s/ when they were produced by a Korean speaker and showed more errors in /p/, /t/, /f/, /ɵ/, and /s/ when they were spoken by an English native speaker. Comparing to the perception of English consonants spoken by a Korean speaker, greater error rates and diverse error patterns were found in the perception of consonants produced by an English native speaker. The present study provides the evidence that prosodic position plays a crucial role in the perception of L2 segments.

This study was to determine general trends with respect to work-family balance perception and psychological wellbeing, examine correlations between related variables, investigate differences in related variables, and understand the effect of work-family balance perception on psychological well-being in married employees. The subjects were 300 married employees living in G city. The subjects completed a questionnaire and data were analyzed using IBM SPSS 21.0. The major findings were as follows. First, the average scores of men and women's self-esteem were higher than the median. Men had a more traditional gender role attitude and higher work-family balance perception level than women. The scores of men and women's depression were lower and life satisfaction were higher than the median. Second, the scores of men and women's work-family balance perception were different according to working hours. Men's psychological well-being were different according to the scale of work place and women's psychological well-being were different according to household working time. Third, depression in married employees were negatively related to life satisfaction. Their psychological well-being were significantly related to work-family balance perception. Fourth, men's depression were influenced by self-esteem, social care service, family${\rightarrow}$work conflict, and work${\rightarrow}$family conflict. Depression in women were influenced by health state, self-esteem, gender role attitude, family${\rightarrow}$work conflict, and work${\rightarrow}$family conflict. Men's life satisfaction were influenced by health state, economic state, and self-esteem. Women's life satisfaction were influenced by health state, economic state, weekly working hours, self-esteem, and work${\rightarrow}$family conflict.

The current study examined English-speaking adult learners' production and perception of L2 Korean stops (/t/ or /t'/ or /t^h/) to investigate whether the two modalities are linked in utilizing voice onset time (VOT) and fundamental frequency (F0) for the L2 sound distinction and how the learners' L2 proficiency mediates the relationship. Twenty-two English-speaking learners of Korean living in Seoul participated in the word-reading task of producing stop-initial words and the identification task of labelling CV stimuli synthesized to vary VOT and F0. Using logistic mixed-effects regression models, we quantified group- and individual-level weights of the VOT and F0 cues in differentiating the tense-lax, lax-aspirated, and tense-aspirated stops in Korean. The results showed that the learners as a group relied on VOT more than F0 both in production and perception (except the tense-lax pair), reflecting the dominant role of VOT in their L1 stop distinction. Individual-level analyses further revealed that the learners' L2 proficiency was related to their use of F0 in L2 production and their use of VOT in L2 perception. With this effect of L2 proficiency controlled in the partial correlation tests, we found a significant correlation between production and perception in using VOT and F0 for the lax-aspirated stop contrast. However, the same correlation was absent for the other stop pairs. We discuss a contrast-specific role of acoustic cues to address the non-uniform patterns of the production-perception link in the L2 sound learning context.

This paper presents the moving object detection and tracking algorithm using edge information base on human perceptual system The human visual system recognizes shapes and objects easily and rapidly. It's believed that perceptual organization plays on important role in human perception. It presents edge model(GCS) base on extracted feature by perceptual organization principal and extract edge information by definition of the edge model. Through such human perception system I have introduced the technique in which the computers would recognize the moving object from the edge information just like humans would recognize the moving object precisely.

Objectives: To assess the nurses' hand hygiene (HH) knowledge, perception, attitude, and self-reported performance in small- and medium-sized hospitals after Middle East Respiratory Syndrome outbreak. Methods: The structured questionnaire was adapted from the World Health Organization's survey. Data were collected between June 26 and July 14, 2017. Results: Nurses showed scores on knowledge ($17.6{\pm}2.5$), perception ($69.3{\pm}0.8$), self-reported HH performance of non-self ($86.0{\pm}11.0$), self-reported performance of self ($88.2{\pm}11.0$), and attitude ($50.5{\pm}5.5$). HH performance rate of non-self was $Y_1=36.678+0.555X_1$ (HH performance rate of self) (adjusted $R^2=0.280$, p<0.001). The regression model for performance was $Y_4=18.302+0.247X_{41}(peception)+0.232X_{42}(attitude)+0.875X_{42}(role model)$; coefficients were significant statistically except attitude, and this model significant statistically (adjusted $R^2=0.191$, p<0.001). Conclusions: Advanced HH education program would be developed and operated continuously. Perception, attitude, role model was found to be a significant predictors of HH performance of self. So these findings could be used in future HH promotion strategies for nurses.

This study reveals the perceptual role of stop release burst to Koreans' recognition of POA(place of articulation) and voicing in the English word-final stops. 10 Korean subjects participated in a perception experiment wherein the stimuli are prepared on the basis of the amount of acoustic information, which includes the release burst. The result shows that i) release burst plays an important role in the recognition of POA in the order of velar, alveolar, and bilabial stops, and ii) the release burst more enhances the correct recognition of voiceless stops than that of voiced stops. This result leads us to conclude that the role of stop release burst differs with respect to the POA and voicing of the stops, and it is possibly related to the different intensity of release in voicing and in each POA.

The purpose of this study was to identify the effect of experience emotion (i.e., happy, proud, sad, fear) on the risk perception. This study also examined interaction effects of emotion regulation (i.e., reappraisal strategy, problem focused strategy) between experience emotion and risk perception. The study collected data from 168 flight crew members in Korean commercial airlines, using an online research in which an experiment of emotion manipulation and a survey were included. The results of the study found the positive effect of happiness emotion on the risk perception regarding cases 1(these cases have high possibility of negative result and low circumstance control) and the positive effect of sadness emotion on the risk perception regarding cases 2(these cases have low possibility of negative result and high circumstance control). This study also found the interaction effect of reappraisal emotion regulation strategy between the relationship of happiness and risk perception regarding cases 2. From these results, the study provided that theoretical and practical implication that happiness and sadness emotion contribute risk perception and reappraisal strategy has a moderating role in the relationship between happy emotion and risk perception. Finally, based on these results, the limitations of this study and future research were discussed.

This study investigates the effect of visual merchandising congruity perception on brand attitude and purchase intention. In addition, this study examines the mediating role of perceived risk in the process. Four retail fashion brands with classic image were selected in the previous research to avoid the influence of different brand images. Questionnaires were distributed to 200 customers leaving the four fashion retail stores which were chosen by the previous research. A total of 167 completed questionnaires were analyzed using SPSS 18.0 and AMOS 7.0 statistical packages. The results were summarized as follows. First, visual merchandising congruity perception positively affected brand attitude. This result supports the match-up hypothesis. Second, brand attitude positively influenced purchase intention. Third, visual merchandising congruity perception did not directly affect purchase intention. Visual merchandising congruity perception indirectly influenced purchase intention by mediating brand attitude; however, it did not directly influence purchase intention. Therefore, the strategic approaches to enhance favorable brand attitude through visual merchandising congruity perception should be tried. Fourth, visual merchandising congruity perception negatively affected perceived risk. Fifth, perceived risk negatively affected brand attitude. Sixth, visual merchandising congruity perception affected brand attitude by mediating perceived risk. Therefore, it is needed to devise the visual merchandising strategy that lowers the perceived risk in order to make a positive brand attitude.

This study aimed to analyze the relationship between the learning perception of aviation service subjects using role play on the interpersonal competence, learning satisfaction, and learning outcomes of college students majoring in aviation service. A survey was conducted targeting 217 university students majoring in aviation service who are enrolled in universities in the metropolitan area and Chungcheong area and have experience in class using role play. In addition, the hypothesis is verified using the structural equation model. Among the perceptions of role play classes experienced by university students majoring in aviation service, 'inter-dependency' was found to have a positive (+) effect on all sub-factors of interpersonal competence. And 'usefulness' confirmed the positive (+) influence relationship with 'temperament for others' and 'communication' except for 'relationship promotion' of interpersonal ability. Among sub-factor of interpersonal competence, it is confirmed that only the factors of 'temperament for others' and 'communication' had an effect on learning satisfaction. And it is proved that learning satisfaction is an important determinant of learning outcomes. Therefore, this study is expected to serve as a basis for deriving an efficient and optimal learning method for practical subjects in aviation service majors.
