The purpose of this research was to determine the relation between clothing evaluative criteria and segmented groups based on the perception of somatotype. The data for this research were collected from questionnaires of 192 females in Busan. Data were analyzed by frequency, factor analysis, cluster analysis, discriminant analysis, and regression analysis. Cluster analysis was used to identify groups of respondents based on the perception of somatotype difference factors. Based on the findings, three distinct groups were clustered: thin, moderate, fat. There were significant differences among the three groups in terms of clothing evaluative criteria. The result of regression analysis revealed that the perception of somatotype is a major determinant to influence the clothing evaluative criteria. The thin group preferred practical clothes while the fat group liked symbol clothes.

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.

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.

This study examined the impact of sonority profiles, positional differences and L2 proficiency on Korean EFL learners' perception of English biconsonantal clusters, using nonce words. The overall results showed that major predictions of the sonority-based typological markedness on consonant clusters were supported, as obstruent plus sonorant and sonorant plus obstruent sequences were better perceived than obstruent only or sonorant only sequences. Yet, some consonant clusters did not show a preference for sonority profiles. Positional effects were also confirmed, as word-initial biconsonantal clusters were better perceived than wordfinal ones across all the participant groups. Participants' English proficiency turned out to be also important in the perception of consonant clusters, since university students' mean rate of accuracy was highest, followed by that of high school students, which in turn followed by that of middle school students. Further, the effects of other factors like frequency and stimuli on speech perception were also addressed, along with some implications for future research.

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.

경체 침체와 고용 없는 성장 산업으로 인해 대학생의 실업 문제가 점차 사회문제로 부각되고 있다. 특히 대학생의 취업률 문제가 대학의 평가로 이어질 정도로 정부가 관심을 갖고 대학생 취업률을 올리고자 노력하고 있다. 따라서 대학의 취업 정책은 졸업자의 취업지원을 위해 다양한 프로그램을 준비하여 대학생 취업을 지원하고 있다. 그러나 대학의 취업지원 활동의 의도, 추진 성과, 준비성 등과 대학생이 인지하는 만족도, 효용성 등 부문에서 일부 차이를 보이고 있다. 이는 활동의 효과에도 문제가 있지만 프로그램 추진의 효율성도 떨어져 예산 낭비로 이어지고 있다. 본 연구는 이러한 대학 취업 지원활동의 효율성과 효과성을 높이기 위해 대학의 지원활동에 대한 대학생의 인지도, 활용도, 만족도 등을 분석하여 대학의 취업 지원 프로그램 수정 제안과 함께 관련 주체들의 바람직한 태도와 정책을 제시하고 있다.

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.

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.
