The aim of this paper is to investigate the relationship between production and perception of Korean vowels by Koreans and Poles. The results of the experiments proved that the relation is not linear and that there might be other factors that influence the perception and production than those investigated here. In most of the cases, the comparison of the formant values (F1, F2) between Koreans and Poles proved to determine the perception. However, in some cases certain vowels pronounced by Poles were not perceived as the intended ones, although they showed no significant differences with those pronounced by Koreans and perceived as they were intended to be.

The purpose of this study was to investigate the perception about AI assistants and the differences between two groups, workers(secretaries) and supervisors(bosses), using the Q-methodology which has an advantage in understanding the types of subjective perceptions. Through literature reviews and interviews, 34 Q-samples were extracted, and then Q-sorting was conducted by P-samples(20 workers and 15 supervisors). As a result of Q-sorting, the types and characteristics of AI assistants perceived by each P-sample were explained. The perception of the workers divided into five distinct types, and the perception of the supervisors was divided into three distinct types. The most crucial factors in distinguishing between workers and supervisors' perceptions depend on whether they are capable of performing certain tasks and whether they can replace existing secretarial jobs. This study, as the primary research on AI assistants, can help to redefine the work that can be replaced by AI and the work that only people can do, and thus to establish education, recruitment, and training plans.

The research is a correlational study to look for causes and factors relating to the design of written documents (professional reading materials) and identify those relationships that are useful for communication designers. The research specifically targeted the relationships between perception and reader's past experiences and appearance of the written documents. A preliminary survey, such as interviews, discussions, questionnaires and brainstorming sessions are conducted to establish the observable attributes related to perception which are reader's interests, importance of information and written documents complexity. Finally, the research used Structural Equation Model (SEM) to identify significant differences and analyze strong and weak correlations between these attributes. In general, the results of the study shows that the attribute appearances of a written documents with excellent visualizations for information display shows a strong correlation with interests while the attributes importance is weakly correlated with the complexity of the documents.

This research examined how pilots perceive risks when faced with emergency flight situations. We had 116 commercial airline pilots evaluate riskiness of 39 non-routine flight situations. The pilots' risk perception was analyzed as a function of their position (captain vs. first officer), expertise (expert vs. novice), and military flight experience (with vs. without military experience). Results showed that captains evaluated potential-risk situations and low-risk situations more dangerous than first officers. However, there were no differences between experts and novices, and between pilots having military flight experience and pilots not having military flight experience in risk perception. The analysis of multi-dimensional scaling revealed that the pilots used controllability as a key dimension for evaluating riskiness, though the other dimensions they used varied with their position, expertise, and military flight experience.

The idea to improve the quality of lighting design in interior spaces has gained importance in the last years. This experimental study concentrates on the quality of lighting and the relation between lighting arrangements and perception. A individual office room having four different lighting arrangements was prepared and the differences between the perception of the participants under each lighting arrangement was evaluated. The results suggested that lighting system and arrangements affect interior perception. Wall washing enhanced the impressions of clarity and order, cove lighting enhanced the ceiling higher respectively and other and tungsten-halogenated uplighting made the same space relaxing, private and pleasant.

Purpose : This study was to examine the relations of perception of physique with self-esteem, sociality and problematic behaviors in children. Methods: Four hundred sixty five (231 boys and 234 girls) children were divided into three groups according to their height or body mass index according to the physical growth standard table had been presented in 2007 by the Korean Pediatric Society. The group 1, 2, and 3 was short, borderline and normal or obese, overweight and normal, respectively. Their perception and satisfaction of height and weight were investigated, and their self esteem and behavior styles were examined with Self-Esteem Inventory (SEI) and Korean Child Behavior Checklist (K-CBCL). We compared the numbers of appropriate perception, satisfaction, self-esteem and problematic behaviors in each group, and analyzed the relationship among perception of physique, self-esteem, sociality, and behavioral characteristics. The collected data were analyzed with chi-square test, ANOVA and Pearson correlation coefficient used with SPSS (ver. 12.0). Results : There were significant mismatches among their real physique perception and satisfaction (P<0.05). There were no significant differences of their self-esteem, sociality, and problematic behaviors according to their actual height and weight. There were significant differences of their self-esteem according to their perception or satisfaction of their height and weight (P<0.01). Conclusion : The children who considered themselves have short stature or obesity had problematic behaviors or low self-esteem. Therefore, children should be educated to have the appropriate perception of their own body image.

Background & Objectives: This study aimed to examine the relationship between subjective health perception and health behaviors among adolescents, utilizing raw data from the 8th Korea National Health and Nutrition Examination Survey (2019-2021) while distinguishing between genders. Methods: The study employed data from the 8th Korea National Health and Nutrition Examination Survey (2019-2020), recruiting students from 1st to 3rd grades in middle and high schools nationwide. Through population stratification, sample distribution, and sampling stages, a final sample of 1,065 adolescents aged 12 to 18 years was selected. The collected data were analyzed using SPSS 28.0 (IBM Corp., Armonk, NY, USA) at a significance level of .05. Results: Regarding the general characteristics of the subjects, no statistically significant differences were observed among male students based on school, family structure, and income. However, among female students, a significant difference in subjective health perception was noted, with higher perception among high school students compared to middle school students (p=.001). Significant differences in health behaviors were identified based on family structure for male adolescents, where those living with both parents exhibited more health-promoting behaviors than single-parent adolescents (p=.011). However, no significant difference was observed among female adolescents. In terms of health behaviors related to gender, regular exercise was found to significantly impact subjective health perception in male adolescents (p=.013), while breakfast habits were identified as significant influencers for female adolescents (p<.001). Conclusions: This study revealed gender differences in subjective health perception and health behaviors among adolescents. Based on these findings, there is a perceived need for the development of health promotion programs tailored to the unique needs of male and female adolescents.

The purpose of the present study was to investigate the differences in purchase behaviors, buying motives of secondhand clothing and the perception toward secondhand clothing products among the groups as determined by their gender and age. Data were collected by a pilot test and the final questionnaire survey administered to 450 subjects in the age range from 20 to 59, living in Seoul; 430 were used for data analyses. The results showed that 3 factors for buying motives (distinction, affordability, and quality & attractiveness) and 2 factors for perception toward secondhand clothes (positive and negative perceptions) were formulated. Women tended to buy more secondhand clothing products for themselves as well as their family, and put more importance on most of selective criteria than men did. The young were more likely to have negative perception and to buy at diverse places. Those having experiences of buying secondhand clothes showed more positive perception on such products. It is expected that this study provides basic information needed for secondhand apparel companies to develop their marketing strategies to increase customer satisfaction.
