In this research, three topics were studied for the elderly. The first was the elderly's error characteristics for tracing task and the second was for depth perception. The characteristics were compared with the young's. Twenty two old people and twenty two young people participated in the tracing experiment, respectively. In the depth perception experiment, twenty three old people and twenty two young people participated. A depth perception apparatus and a tracing one were used in the experiment. In the depth perception error, a significant difference was not detected on gender. However significant differences were detected with age and viewing distance. In the tracing error, significant difference was detected with age, also. The third experiment was push-button operation and fifteen old people participated in the experiment. As the result, operation time error was increased with the button size and the moving distance. The result of this study will be able to be considered in its user interface design to reduce the elderly's error while using a product.

This study analyzed the differences in value perception and purchasing intention for natural cosmetics by LOHAS class and investigated what influences people's value perception for natural cosmetics had on their purchasing intention. Total 450 questionnaires were distributed to adults of over 20s to 50s for the period from Dec. 1, 2011 to Dec. 14 and 410 questionnaires were used as analysis data. As for collected data, the statistical package SPSS 18.0 Version was used for factor analysis, frequency analysis, reliability test, one-way ANOVA, Chi-Square test, Scheffe-test, correlations analysis and multiple regression analysis. LOHAS class was divided into three groups (higher, middle and lower) based on LOHAS index. Through factor analysis, the value perception for natural cosmetics were divided into three factors (social value, emotional and functional value perception). The results of this study were obtained as below. First, in case of the value perception for natural cosmetics by LOHAS class, it was demonstrated that the higher LOHAS classes they were, the higher value perception for natural cosmetics (social, emotional and functional value perception) they had. Second, in case of the effects of the value perception for natural cosmetics by LOHAS class on their purchasing intention (intention to use and recommendation of usage), it was found that their value perception influenced their purchasing intention. Social value perception and functional value perception, especially social value perception largely affected the purchasing intention of all LOHAS classes, while emotional value perception didn't affected the purchasing intention.

The present study examined if individual listeners' perceptual variations were associated with their cognitive characteristics indexed by the Autistic Spectrum Quotient (AQ). This study first investigated the perception of the lexical pitch accent contrast in the Kyungsang Korean currently undergoing a sound change, and then tested if listeners' perceptual variations were correlated with their AQ scores. Eighteen Kyungsang listeners in their 20s participated in the perception experiment where they identified two contrastive accent words for auditory stimuli systematically varying F0 scaling and timing properties; the participants then completed the AQ questionnaire. In the results, the acoustic parameters reporting reduced phonetic differences across accent contrasts for younger Kyungsang generation played a reliable role in perceiving the HH word from HL, suggesting the discrepancy between the perception and the production in the context of sound change. This study also observed that individuals' perceptual variations were negatively correlated with their AQ sub scores. The present findings suggested that the sound change might appear differently between production and perception with a different time course, and deviant percepts could be explained by individuals' cognitive measure.

The aims of the present study are two-fold: 1) to explore differences on speech perception between younger and older adults according to noise conditions; and 2) to investigate which cognitive domains are correlated with speech perception. Data were acquired from 15 younger adults and 15 older adults. Sentence recognition test was conducted in four noise conditions(i.e., in-quiet, +5 dB SNR, 0 dB SNR, -5 dB SNR). All participants completed auditory and cognitive assessment. Upon controlling for hearing thresholds, the older group revealed significantly poorer performance compared to the younger adults only under the high noise condition at -5 dB SNR. For older group, performance on Seoul Verbal Learning Test(immediate recall) was significantly correlated with speech perception performance, upon controlling for hearing thresholds. In older adults, working memory and verbal short-term memory are the best predictors of speech-in-noise perception. The current study suggests that consideration of cognitive function for older adults in speech perception assessment is necessary due to its adverse effect on speech perception under background noise.

This study aims to explore the diverse characteristics of obese groups of Korean males in their 20's to 40's. A total of 201 males who each had a BMI (Body Mass Index) of 23 or over were recruited through a convenient sampling. Samples were categorized into groups of overweight, slightly obese, and severely obese, and submitted for data analysis. Results are summarized as follows. First, in terms of demographic characteristics, slightly and severely obese males were older than overweight males. There were also group differences in marital status and household income. Second, slightly and severely obese groups demonstrated a higher perception of obesity and a lower perception of health than did the overweight group. Third, there were no group differences in body satisfaction, socio-cultural attitudes toward appearance, and self-esteem. Based on these results, we concluded that overweight, slightly obese, and severely obese groups were distinguishable from each other in terms of their demographic characteristics, whereas the slightly obese group and the severely obese group were not different in terms of perception of obesity, perception of health, weight control behaviors, body satisfaction, body image, socio-cultural attitudes toward appearance, and self-esteem. These findings may reflect that people may not become increasingly sensitive to socio-psychological stimulations as they gain more weight if they have exceeded a certain level of obesity. This observation provides meaningful implications for the differences among obesity groups given the lack of prior research focusing on this issue.

The purposes of this research are to find out the standards which mothers consider seriously when choosing a day care center and mother's perception for the quality criteria of day care center, and to estimate the differences of these according to region. The sample consisted of 568 mothers with children using day care center located at the city of Taegu and Dalsung Gun. Collected data were analyzed by frequency, Percentage, chi-square, t-test, chronbach's $\alpha$. The results are summerized as follows : 1. In mother's perception for the quality criteria of day care center, the mothers living in the large city perceived more importantly in staff qualifications, administration - evaluation, staff- parent/staff- child interaction, curriculum, staffing, physical environment nutrition, health and safty than mothers in rural community. 2. In the importance classified by domains of the quality criteria of day care center, there were statistically significant differences according to the variable of region in staff qualifications, staff-parent/staff-child interaction, curriculum, staffing, physical environment 3. Given the present situations (income, transportation, location of workplace, etc.), when mothers choose a day care center, generally, staff-parent/staff-child interaction was the most important factor. And according to region, the distance to workplace or home was the most important factor in the case of mothers living in the large city, on the other hand, staff-parent/staff-chad interaction was the most important factor in the case of mothers living in rural community when mothers choose an ideal day care center, generally staff-parent/staff-chad interaction was the most important selection standard, and there were not remarkable differences according to region.

Due to the economic recession and corporation's growth without more jobs, college graduates unemployment issue has been emerged as a serious social problem. Since the employment rate of each college became an important factor of college evaluation by the government, each college is trying to increase the employment rate of students. Therefore universities are supporting student employment through various policies and programs. However there have been perception differences in intention of employment supporting activities, final results, preparedness, student satisfaction level and overall effectiveness level of program between students and university career center staff members. The perception differences may lead not only to the waste of budget but also ineffectiveness of various programs to promote student employment. Therefore this research proposed new revised efficient employment supporting programs of universities and desirable attitude of students to increase the effectiveness of student employment based on the analysis of perception level on the several issues such as degree of usefulness of program and satisfaction level of students.

This study has aimed at establishing of the new administration scheme related to the goal of police like the investigation division through analyses of differences on the role perception of female police officers. In a related matter, work characteristics include ranks, working areas, working priods and the dependent variables of the role perception of female police officers are composed of 3 items like task role, group maintenance role and individual role. As a result, the differences by ranks, working areas, working priods that were analyzed by using one-way ANOVA showed significant differences in the each dependent variables. The results showed that the female police officers whose ranks were higher, who had been employed longer, and whose working areas were places where the cases occurred a lot more showed great point in mean value not only on task role but also on group maintenance role. The result of the study suggests a direction to achieve the best efficacy of police duties such as a criminal investigation, the prevention of crime and presents an useful indication to redefine the role.

The purpose of this study was to investigate differences in the perception and attitudes of middle school students toward food safety between those who possess high behavioral intentions to prevent contracting a foodborne illness and those who do not. The survey collected 871 usable data from several middle schools in Seoul, Korea in July 2007. Using six behavioral intention measurement items, a two-step cluster analysis approach was conducted resulting in a strong intention group and a weak intention group. Perception and attitudes toward foods safety were different between the two groups. Students with strong behavioral intentions to prevent foodborne illness tended to possess a stronger perception and attitude toward various food safety issues. Students with strong intentions were more certain of consumer's right to purchase safe foods, more concerned about foodborne illness and food safety, believed that the government should put more efforts toward establishing a safe food chain, possess more distrust for food suppliers, were more aware of specific foodborne illness pathogens, had more food safety education/training, and washed their hands more frequently than those with less strong intentions. No significant differences were found between the groups but,overall, chemical residues and food additives were perceived as more harmful and more serious food safety issues than those of foodborne illness pathogens despite that microorganisms are the main cause of foodborne illness outbreaks in schools. Participants seemed to underestimate the importance of temperature control for preventing foodborne outbreaks. Several implications and suggestions on how to improve the behavioral intentions of middle school students to prevent possible foodborne illness were provided.
