The goal of 3D stereoscopy is not only to maximize positive experiences (such as sense of realism) by adding depth information to 2D video but to also minimize negative experiences (such as fatigue). This study examines the impact of different depth levels induced by adjusting 3D camera convergences on positive and negative experiences and finds an optimal parameter for viewers. The results show that there are significant differences among depth levels on spatial involvement, realistic immersion, presence, depth perception, screen transmission, materiality, shape perception, spatial extension and display perception. There are also significant differences for fatigue and unnaturalness. This study suggests that reducing the camera convergence angle of an object by $0.17^{\circ}$ behind the object is the optimal parameter in a 3D stereoscopic setting.

In this study, we compared how different the self-perception and the daily hassels between the Korean and American children. The subjects were 706 fifth and seventh grade students. Data were obtained by administrating a questionnaire. The instruments used for this study were self-perception profile for children scale(SPPC) and stress scale. 1. All the SPPC factors for Korean children was significantly lower than those for American children. The SPPC fators for American children didn't show any significant differences by grades. But for Korean children seventh graders showed significantly lower SPPC than fifth graders. 2. The most significant factor to predict the golbal self-worth was physical appearance for boys and girls. Self perception for physical appearance is more influential factor than scholastic competence to form the positive self-perception for both boys and girls. 3. The daily hassels for Korean children were significantly higher than those for American childredn. Also daily hassels for seventh graders were significantly higher than those for fifth graders. 4. Daily hassels global self worth correlated negatively. When the level of stress was increased, the global self-worth was decreased.

The purpose of this study is to compare the differences in human rights perception between people with disabilities and staffs in the disabled residential facilities. Using data from the '2014 Human Rights Survey on Disability in the Disabled Residential Facilities' for 602 facilities, the study compared their perception of human rights(16 items), including human rights guarantee(12 items) and human rights violation(4 items). Result showed that the rate of perception for human rights guarantee and violation(except staff violation) of staffs was higher than people with disabilities(p<.05). This study demonstrated that there were significant differences in human right perception between people with disabilities and staffs. The cause of this difference would be the conflict between roles of staff and needs of person with disabilities, absence of human rights indicators by mutual consent between the two. Our findings suggested a need for study on strategies to solve gap of perception between the two, such as integrated human rights education, developing consensual human rights indicators.

The purpose of this study was to evaluate the maternal perception of her newborn and identify the risk of mother-infant relationship. Broussard's Neonatal Perception Inventories were completed by 113 mothers on the first or second postpartum day (Time I ) while they were still in the University Hospital. These inventories were again administered when the infants were approximately one month of age (Time Ⅱ). The data was analyzed by S.P.S.S. program and the results were as follows: 1) There were differences between the mothers' exportations of the average baby and perceptions of their babies at Time I and Time Ⅱ (p<0.01). 2) The maternal perception of her newborn at Time I was not related with the education, the parity, the experience of abortion, the type of delivery and the sex of baby but related with the method of feeding (p<0.05). 3) The maternal perception of her newborn at Time Ⅱ was not related with the education, the parity, the experience of abortion, the type of delivery and the method of feeding but related with the sex of baby (p<0.05). 4) The changes of maternal perception between Time I and Time Ⅱ were not related with the education, the parity, the experience of abortion, the method of delivery and the sex of baby but related with the method of feeding (p<0.1). 5) The maternal perception of the newborn was not correlated with the age and the duration of labor.

This study analyzed risk perception and risk reduction behaviors of male and female college students in their twenties who purchased fashion products in internet shopping malls. It also investigated the relationship between risk perception and risk reduction behavior as well as the ways in which groups, categorized by risk perception, differed in their risk reduction behaviors. The results of this study were as follows: first, seven factors of risk perception were identified. These were product quality, shipping, product image, payment, economic feasibility, fear of other people's reactions, and size. Six types of risk reduction behavior were also identified. These were product comparison, word-of-mouth information search, price search, preference for name-brand, service comparison, and referring to experiences. Next, a correlational analysis of the factors of risk perception and those of risk reduction behavior showed several patterns. The highest positive correlation was between economic risk perception and product comparison behavior. In addition, shipping risk perception was positively correlated with service comparison behavior and product quality and product image had a positive correlation with word-of-mouth information search behavior. Third, customers of internet shopping malls could be categorized into three groups: shipping risk perception group, high risk perception group, and product quality risk perception group. The groups were shown by factor analysis to be significantly different to each other. Finally, risk reduction behavior was investigated according to the different groups of risk perception of the internet shopping malls and the results showed significant differences among groups.

The purpose of this study is to investigate the self-perceptions of the elementary school students' on the affective, behavioral and cognitive domains in science class. To see if there are differences in students' perceptions according to grade levels, a self-perception questionnaire was applied to third and fifth grade students in Seoul, Korea. The major results of the study are as follows. First, the perception level of the affective domain was higher than that of the cognitive domain in third grade students. There was no significant difference in the self-perception level of the fifth grade students. Both third and fifth grade students perceived the greatest improvement in the cognitive domain through one year of science teaching. Second, in the life science class, the same tendency was also observed. The students in the third and fifth grade reported that cognitive domains were the most improved through the one-year life science class. Third, when the students' perceptions were compared by grades, the third grade students showed higher self-perception scores than fifth grade students. As the grade increased, the perception scores of the students' lowered. Based on these findings, implications for science education research and teaching and learning at school are discussed.

Purpose: This study aimed to investigate the factors influencing the nursing profession perception of nursing students. Methods: Data were collected with a questionnaire distributed to 305 nursing students in U city. Data were collected from March 30 to June 15, 2019. Data analysis was performed using the SPSS 22.0 program. Results: There were significant differences in the level of interpersonal trust (F=5.42, p<.001), empathy ability (F=3.13, p=.015), interpersonal relationship ability (F=3.64, p=.006) and nursing profession perception (F=11.95, p<.001) on the major satisfaction. The level of interpersonal trust (r=.21, p<.001), empathy ability (r=.27, p<.001) and interpersonal relationship ability (r=.28, p<.001) were positively correlated with nursing profession perception. Also empathy ability (r=.11, p=.047), interpersonal relationship ability (r=.49, p<.001) with interpersonal trust and correlation of empathy ability with interpersonal relationship ability (r=.32, p<.001) were positively correlated with each other. The significant variables that influence the nursing profession perception were grade, major satisfaction, empathy ability and interpersonal relationship ability. These factors were responsible for 21.3%. Conclusion: The results of this study indicate that educational programs are necessary to raise the nursing perception of nursing students and reduce the turnover of nurses.

Korean L2 speakers have many problems learning the pronunciation of English words. One of these problems is vowel epenthesis. Vowel epenthesis is the insertion of vowels into or between words, and Korean learners of English typically do this between successive consonants, either within clusters, or across syllables, word boundaries or following final coda consonants. The aim of this study was to investigate whether individual differences in vowel epenthesis are more closely related to the perception and production of segments (vowels and consonants) and prosody or if they are relatively independent from these processes. Subjects completed a battery of production and perception tasks. They read sentences, identified vowels and consonants, read target words likely to have epenthetic vowels (e.g., abduction) and demonstrated stress recognition and epenthetic vowel perception. The results revealed that Korean second-language learners (L2) have problems with vowel epenthesis in production and perception, but production and perception abilities were not correlated with one another. Vowel epenthesis was strongly related to vowel production and perception, suggesting that problems with segments may be combined with L1 phonotactics to produce epenthesis.

Purpose: This study was done to identify the relationships of perception of JCI (Joint Commission International) hospital accreditation, nursing performance, self-concept and retention intention in nurses. Methods: Self-administered questionnaires were used to collect data from 199 JCI-accredited nurses in general hospitals located in Gyeonggi Province. Data collection was done in May 2015 and analyzed using t-test, ANOVA, $Scheff{\acute{e}}^{\prime}s$ test, and Pearson correlation coefficients. Results: The scores for perception, and nursing performance were (on a five-point Likert scale) 3.34, 3.78 respectively, and self-concept and retention intention were (on a eight-point Likert scale) 5.40 and 5.21 respectively. Nurses' perception, nursing performance, self-concept, and retention intention showed significant differences depending on age, marital status, education, department, work experience, position, Korean accreditation, and JCI accreditation. A positive correlation was observed between perception, nursing performance, self-concept, and retention intention. Conclusion: The results of this study indicate that enhancing positive perception and good nursing performance can produce good self-concept and retention intention.

Purpose: This study aimed to assess the perception and performance of antimicrobial stewardship among clinical nurses and to contribute to establishing their role through an Importance-Performance Analysis(IPA) matrix. Methods: The study included 203 nurses working in hospitals of general hospital level or higher. Data collection took place from April 9 to May 6, 2024. Data analysis involved descriptive statistics, t-tests, ANOVA, Scheffé tests, and IPA analysis. Results: The average perception score for antimicrobial stewardship was 4.42±0.46, while the performance score was 3.96±0.53. Significant differences in perception and performance were observed across several ares: observation of patients, checking with/suggesting to physician based on assessments, implement tests and antimicrobial administration, patient education and support, coordinating multiple disciplines and institutions, acquiring up to date knowledge(p<.050). Perception was highest in the area of implement tests and antimicrobial administration but lowest in coordinating multiple disciplines and institutions. Conclusion: To establish the specific role of nurses in antimicrobial stewardship, improving nurse perception and fostering collaboration with various experts are essential. Developing educational programs and institutional support tailored to nurses is necessary to address areas identified for improvement in both perception and performance.
