  • This study aimed to investigate the correlation between speaker's chronological age (CA) and perceived age (PA) and to specify the effect of pitch and speech rate as acoustic cue on judging age, using perceptual testing and acoustic analysis. Three tasks were conducted to identify the degree of listener's accuracy about age estimation. Three perception tasks were conducted to measure the accuracy of 80 Korean listeners when presented with different types of speech. In all the tasks, participants listened to speech samples and gave their estimate of the speaker's age in figures. It was found that Korean listeners are able to gauge the age of a speaker fairly precisely. CA and mean PA were positively correlated in all three tasks. It is clear that the amount and type of information included in the voice samples affected the accuracy of a listener's judgement. Moreover, the result revealed that listeners make use of acoustic information such as pitch and speech rate to estimate speaker's age.

  • Purpose: This study was conducted to describe mother's child-rearing attitudes and problem conduct of children as perceived by children and to examine correlation between maternal nurturing attitudes and child problem behavior. Method: The participants were 338 fifth and sixth graders who attended two randomly selected elementary schools in the city of G, Gangwon province. Child-rearing attitudes of the mother were rated on a 5-pointed scale that developed by Schaefer and added by Oh & Lee(1982). Problem conduct of children were rated on a 3-pointed scale of the K-YSR by Oh Kyung-Ja et al.(1997). The data were gathered from October 2 to October 28, 2004, and the collected data were analyzed with SPSS 10.0 program. Results: For the children's perception of mother's child-rearing attitude, student had a relatively high mean scores of 3.70±0.44. Correlations between the mother's child-rearing attitude and general characteristics of the children showed statistically significantly different according to grade, father-mother relations, type of residence and extent to which father shared household chores. The mean score for problem conducts of children was 0.47±0.25. The average for their internal behavior problems was 0.52±0.33, and for external behavior problems was 0.44±0.24. There were statistically significantly differences in the behavior problem scores of the children according to the general characteristics of grade, education, occupation, mother-father relations, extent to which father shared in household chores and religion. As to correlation between mother's child-rearing attitude and their problem conduct, every type of attitude had a significantly moderate reverse correlation to every type of behavior problem of the children(r=-.431, p=.000). Conclusion: Mother's child-rearing attitudes might affect the problem conduct of children, and mother should try to treat their children with affection and respect, to maintain good relations with father, and to bring their children up coherently in an autonomous, permissive, positive and democratic manner.

  • In this study, we investigated that consumers could differentiate between levels of claims and clarify how a visual aid influences consumer understanding of the different claim levels. We interviewed 2,000 consumers in 13 shopping malls on their perception of and confidence in different levels of health claims using seven point scales. The average confidence scores given by participants were 4.17 for the probable level and 4.07 for the possible level; the score for the probable level was significantly higher than that for the possible level (P < 0.05). Scores for confidence in claims after reading labels with and without a visual aid were 5.27 and 4.43, respectively; the score for labeling with a visual aid was significantly higher than for labeling without a visual aid (P < 0.01). Our results provide compelling evidence that providing health claims with qualifying language differentiating levels of scientific evidence can help consumers understand the strength of scientific evidence behind those claims. Moreover, when a visual aid was included, consumers perceived the scientific levels more clearly and had greater confidence in their meanings than when a visual aid was not included. Although this result suggests that consumers react differently to different claim levels, it is not yet clear whether consumers understand the variations in the degree of scientific support.

  • Purpose: This study investigated Korean women in between age 30 to 60 who were obese or overweight in order to explore their self-perception based on lifetime phase. Methods: Focus group interviews were performed four times with six to eight participants in each group (a total of 27). Data were analyzed using inductive thematic analysis. Results: The data analysis from the interviews revealed recurring common themes: heavy heart, heavy body, resigned acceptance of their own condition, and compromise. The study also found that each age group had different concerns: concerning others' gaze on their obese appearances (30s), realizing their aging obese appearances (40s), recognizing red flags of their health with obesity (50s), and becoming ambivalent about their obese appearances (60s). Overall, their perceptions of being overweight were negative and stressful. Women in their 30s and 40s were more interested in their appearances, and thus were more obsessive about weight gain. In contrast, women in their 50s and 60s were more accepting of their physical appearances, and thus were more concerned about living healthy than losing weight. Conclusion: These results may be useful to consider when developing tailored weight-control programs for obese and overweight Korean women. Additionally, strategic approaches for successful and effective programs targeting healthy weight should be based on better understanding about women's self-perceptions and motivations.

  • Purpose: Indoor thermal comfort can be identified by combination of temperature, humidity, and air flow, etc. However, most thermal indexes in regard to thermal comfort are temperature dominant since it has been considered as a significant factor affecting to indoor thermal comfort The purposes of this study are to investigate indoor neutral temperature range of young Koreans with humidity perception, and to introduce a neutral temperature for temperature preference as well as temperature sensation in order to define the neutral temperature range chosen by occupants. It could be used as basic data for heating and cooling. Method: 26 research participants volunteered in 7 thermal conditions ($18^{\circ}C$ RH 30%, $18^{\circ}C$ RH 60%, $24^{\circ}C$ RH 30%, $24^{\circ}C$ RH 40%, $24^{\circ}C$ RH 60%, $30^{\circ}C$ RH 30%, $30^{\circ}C$ RH 60%) and completed subjective assessment in regard to temperature/humidity sensation and preference twice per condition in an indoor environmental chamber. Result: In RH 30%, sensation neutral temperature was $25.1^{\circ}C$ for men and $27.0^{\circ}C$ for women, and preference neutral temperature was $25.5^{\circ}C$ for men and $27.8^{\circ}C$ for women. In RH 60%, sensation neutral temperature was $23.6^{\circ}C$ for men and $25.9^{\circ}C$ for women, and preference neutral temperature was $23.4^{\circ}C$ for men and $26.3^{\circ}C$ for women. Neutral temperature increased with increasing relative humidity. Women were sensitive to humidity changes. Men expressed humidity changes as temperature variations. In most conditions, preference neutral temperatures were higher than sensation neutral temperatures, however, the preference neutral temperature for men in humid condition was lower than the sensation neutral temperature.

  • It has been suggested that primates' trichromatic color vision is an adaption for folivory and frugivory. Ripened fruit frequently is red against a green background. Given this, the question for our research was whether the ecological relationship between red and green plays any role in figure-ground organization that is an essential step in forming our perception of objects? In this study, it was tested which color looked most strong as a figure, using a red circle on a green background and a green circle on red background. The results of Experiment 1 showed that most participants saw the red circle for the figure more than the green circle. However, this effect was significant only in females, but not in males. Accordingly, this result suggests that the visual development of figure-ground organization based on red-green color combination may differ between males and females. In Experiment 2, it was surveyed that the results of Experiment 1 was simply not by the sex difference of color preference. The gender difference of the figure-ground organization on red-green stimuli are discussed in terms of some recent hypotheses such as gatherer-hunter hypothesis.

  • The purpose of this study is to investigate PR-VEP characteristics on the perception function(S/N) and the judgement function(T/F) of MBTI. The 136 study participants, over 20 years old adults, were examined by PR-VEP and MBTI test for two months in July and August in 2013. PR-VEP was conducted in O1 and O2 by 32 channels EEG system and MBTI test was measured by Form-M online. We found that the time interval(Duration) between N75 and P100 of PR-VEP was 5.49 ms significantly shorter in the group preferring S indicator. And the latency until N75 was 4.83 ms significantly shorter in O1 and 4.27 ms shorter in O2 in the group preferring F indicator. According to these, the characteristics of groups preferring S and F indicator have influence on visual cognitive function, which is meaningful that the interpretation of brain-science can be used with recognition/judgement function of MBTI.

  • The purpose of this study is to investigate the factors that influence consumers' adoption of performance infants' wear made of functional textiles. Based on Innovation Diffusion Model, product attributes, consumer traits, and communication characteristics were considered. A survey was carried out with a convenience sample of 241 housewives who have infants under 4 year-old, living in the Seoul metropolitan area. To analyze the data, SPSS 10.0 was used employing ANOVA, Duncan's post-hoc comparison, $X^2$, and f-test. The participants were classified into 4 groups based on their levels of adoption of performance infants' wear: No-Cognition, Negative Attitude, Positive Attitude, and Purchasing groups. There were significant differences among the four groups in terms of their perception of product attributes, communication characteristics, and personal traits. In terms of product attributes, the Positive Attitude group and Purchasing group showed higher perception of relative advantage, compatibility, trialability and observability than other groups. These groups were also high in terms of their tendency of actively seeking for additional product information, and particularly relied on the information from experts on TV or the Internet, personal experience posted on the Internet, or their own experience. Those who were in professional, well-educated and high income brackets were more likely to be Purchasing group than Positive Attitude group, which means once the positive attitude was formed they are likely to purchase the product.
