A few studies have shown that the function of fusiform face area is selectively involved in the perception of faces including a race difference. We investigated the neural substrates of the face-selective region called fusiform face area In the ventral occipital-temporal cortex and same-race memory superiority In the fusiform face area by the event-related fMRI. In our fMRI study, twelve healthy subjects (Oriental-Korean) performed the implicit distinction of the race while they consciously made familiar-judgments, regardless of whether they considered a face as Oriental-Korean or European-American. In the race distinction as an implicit task, the fusiform face areas (FFA) and the right parahippocampal gyrus had a greater response to the presentation of Oriental-Korean than European-American faces, but in the consciously race distinction between Oriental-Korean and European-American faces, any significant difference in the FFA was not observed. These results suggest that different activation in the fusiform regions and right parahippocampal gyrus resulting from same-race memory superiority could be implicitly taken place by the physiological processes of face recognition.

Hotel companies have to offer well furnished of a lodging and a meal and must keep the best customer supporting service. Because, customers have very strict standards and require fancy service to hotel that they pay. The Customers have different criteria to select hotel according to their purpose such as accommodation, banquet or convention. Hotel recognitions are also different along the purposes. I analyzed effects of hotel choice by intention to use hotel of customers in this research. To verify the effects, I used a structured model by AMOS 4.0 This study results show that the customers chose hotel in accordance with their intention of stay ; accommodation, banquet or convention etc. However, it is not significant hypothesis, that the guests select hotel along the brand recognition or the service perception.

The recent increase in the production of 3D contents allowed viewers to experience various 3D contents. However, some of the viewers did not experience 3D depth well. Several researches were done in past to measure viewers' 3D depth perception, but these researches were done with certain limitations. In this paper, we measured viewers' 3D depth perception and recovery rate in relation with the changes in binocular disparities, saturation, and brightness values after subjects' watching 2D/3D contents. The results showed that when viewers watched the 3D content with positive binocular disparities for 42 minutes, viewers felt that the object seemed to have moved further forward than it was before; with 3D content with negative binocular disparities, viewers felt that the object seemed to be moved backwards. We found that the locational differences of the object in positive disparities were greater than those in the negative binocular disparities. The recovery rate was computed by comparing two measured values of before and after watching 3D contents for 30 minutes. On average, after 30-minute break, viewers showed roughly 50 % of recovery rate.

The purpose of this study was to establish an effective strategy for smoking cessation programs of adult by examining the relationship between smoking and oral characteristics in 166 men in their 20s in Ulsan and Busan. As a result, there was a difference in dental fear (χ²=4.72, p<0.01), tooth stain (χ²=10.22, p<0.01) and others perception of bad breath (χ²=7.35, p<0.01). Smokers had 2.03 times more dental fear, 3.26 times more tooth stain, and 2.51 times more other perception of bad breath higher than non smokers. Therefore, effective smoking cessation education should be continuously operated in order to prevent 20-year-old men from leading to lifetime smoking.

This study sought to find out the status of medical libraries in Korea that provide information services related to the Covid-19 situation, and how the librarian's perception of the Covid-19 situation, the main body of the library's information provision, affects the provision of related information services. For this purpose, we checked the website for Covid-19 information service. In order to understand the degree of awareness of Covid-19, Grunig's Situational Theory was applied to classify four types of librarians according to the degree of problem recognition, constraint recognition, and involvement recognition, and to analyze how the three perceptions affect Covid-19 related information services. As a result, only 25 out of 144 korean medical libraries provided information services related to Covid-19. The librarian, the main agent of the library's information provision, found that the problem recognition and involvement recognition in the Covid-19 situation were high, constraint recognition were low, and the level of information service was very active. And only constraint recognition has been shown to have a significant impact on providing Covid-19 related information services. Further research when future sources are available and follow-up research on how librarians' perceptions affect library operations are also proposed.

The purpose of this study is to understand the effect of people who have heard of 'reading aloud' on the formation of reading satisfaction and reading attitude, and to obtain implications for the library book reading service. To this end, a survey was conducted on 439 people of various age groups. The results are as follows. First, there was a difference in value perception and satisfaction with reading books by age group, and there was no difference in reading attitude. Second, the satisfaction of the respondents who answered that the value of reading books was efficacy and feeling loved was positive, and the satisfaction of the respondents who answered that they were comfortable was lower than this. Third, the more positive the satisfaction level was, the more positive the reading attitude was. Fourth, respondents who participate in reading groups for children were found to have a high value perception of trust relationships and more experience in reading books, and the more experience they have in reading, the more they are affected by the behavioral aspect of reading attitude. Therefore, librarians (teachers) need to support the improvement of reading attitudes by actively operating reading groups for parents while planning programs that take into account value recognition types and satisfaction by age group.

This study aims to understand the differences in cultural and emotional perceptions about the color image of public healthcare facilities in Romania, an Eastern European country that is relatively lacking in recognition but is gradually expanding trade. For this, color images were selected through a review of previous studies, and a questionnaire survey was constructed based on the colorimetric data by visiting 8 public healthcare facilities such as medical facilities, 4 social sports facilities, and 8 nursing facilities. An online survey was conducted on the color image of public facilities with 89 Koreans and 86 Romanians, and frequency and cross-analysis was conducted using the SPSS statistical analysis program to examine the color images of public healthcare facilities of Koreans and Romanians. The difference in perception was identified. As a result, it was found that there was a statistically significant difference in the perception of color images of public healthcare facilities between countries in vocabulary evaluation and image evaluation, and this was interpreted as different meanings for groups residing in different cultures. Therefore, it implies that cultural differences in perception should be considered when establishing an environment related to this in the future.

The purpose of the research is that how awareness of importance of personal medical data, laws regarding personal medical data and perception gap regarding information of medical data system may affect usage of hospital convenience between a regular patient who has experienced hospital service and medical professionals. Preceding research analysis was conducted previous on establishing research model; 150 questionnaires to a regular patient and 150 questionnaires for a medical professional, total of 300 questionnaires were gathered for conducting a question investigation. First of all, the research concluded that there are a regular perception differences between a regular patient and medical professional. Moreover, there are perception differences among the different gender, age, and area of residence. Furthermore, medical professionals tend to consider that convenience of hospital usage will be increased if user strengthens recognition of security of personal medical data. Results of hypothesis stress that higher awareness of exposure of personal medical data and medical information system affect decision making convenience for a better usage of hospital. On the other side, awareness of laws related with personal medical information security does not affect decision making convenience of hospital usage and transaction. The results of the research analyzes with proof that strengthening awareness of personal medical data security positively increase convenience of decision making and transactions in selection of provided medical service.

Background and Objectives: This study aimed to evaluate the audiologic results after cochlear implantation (CI) in older patients and the degree of improvement in their quality of life (QoL). Subjects and Methods: Patients over 65 years old who underwent CI at implant center in Bozyaka Training and Research Hospital were included in this study (n=54; 34 males and 20 females). The control group was patient over 65 years old with normal hearing (n=54; 34 males and 20 females). We administered three questionnaires [World Health Organization Quality of Life-BREF (WHOQOL-BREF), World Health Organization Quality of Life-OLD (WHOQOL-OLD)], and Geriatric Depression Scale (GDS) to evaluate the QoL, CIrelated effects on activities of daily life, and social activities in all the subjects. Moreover, correlations between speech recognition and the QoL scores were evaluated. The duration of implant use and comorbidities were also examined as potential factors affecting QoL. Results: The patients had remarkable improvements (the mean score of postoperative speech perception 75.7%) in speech perception after CI. The scores for the WHOQOL-OLD and WHOQOL-BREF questionnaire responses were similar in both the study and control groups, except those for a two subdomains (social relations and social participation). The patients with longer-term CI had higher scores than those with short-term CI use. In general, the changes in GDS scores were not significant (p<0.05). Conclusions: The treatment of hearing loss with CI conferred significant improvement in patient's QoL (p<0.01). The evaluation of QoL can provide multidimensional insights into a geriatric patient's progress and, therefore, should be considered by audiologists.
