  • This research investigated the cross-modal correspondence between the turbidity and taste of beverages. For an empirical study, we employed two types of achromatic beverages: rice wine and a soft drink. The turbidity of each drink varied between 0.0625~32 g/L, and 0.0078~4 g/L, respectively, and the stimuli were prepared in ten levels according to cognitive turbidity. In the study, participants (N=35) rated each drink stimulus using a 3-point Likert scale with regard to five basic tastes: sweet, salty, bitter, sour, and preferred. In addition, six specific tastes were included that deliberately describe rice wine and the soft drink. Three were yeasty, alcoholic, and astringent for the rice wine, and the other three were creamy, bubbly, and syrupy for the soft drink. Based on participants' assessments, the turbidity of rice wine is highly positively correlated with all five basic tastes. In contrast, the turbidity of the soft drink was positively correlated with sour only. Concerning preference, the most preferred turbidity of rice wine was 4.6~20 g/L, which is close to the turbidity of existing products on the market. Furthermore, except for astringent and syrupy, all tastes were influenced by the turbidity, which implies the potential of turbidity as a new visual parameter to communicate the taste experience of beverages.

  • Objectives : To save the lives of patients with cardiac arrests, CPR must be performed rapidly and precisely. Regarding its critical necessity, there is a growing tendency to encourage whomever witnesses the cardiac arrest to perform basic CPR. However, the attitude toward basic CPR nor its current state of education in Korean Oriental Medical arena, which is one of the dual axes unique to Korean medical system, are not known. This is a kind of pilot study to research attitudes toward and the educative effect of basic CPR among oriental medical doctors in Korea. Methods : We carried out surveys and tests targeting nineteen apprentice doctors working in Dongguk University Ilsan Oriental Hospital, who were receiving training for 'AHA BLS course for healthcare providers', on the attitude toward and educative effect of basic CPR before and after the education. Results : The pre-educational survey showed that most of the participants felt the necessity to be trained in the BLS course, were not confident about performing CPR, and not well-acquainted with the whole process of performing CPR. After education, however, none of them responded with a lack of confidence to perform basic CPR, and the score of the confidence to perform basic CPR was significantly increased, too (from $2.05{\pm}0.71$ to $4.05{\pm}0.40$, n=19, p<0.001). Moreover, all of them answered they were satisfied with this BLS course, and it aroused their sense of responsibility as oriental medical doctors. All the participants passed the exam, and their average score for BLS scheme performance was $28.2{\pm}1.3$. Conclusions : It is necessary, in the future, to set up a management system for intensive, regular and continuous reeducation and expand the research on the perception and attitude targeting larger numbers and more multilevel groups of oriental medical doctors.

  • Social and psychological experiences in human-agent interactions are becoming more important than the task-oriented efficiency, as the influence of computer agents increases and human-agent interaction develops similarly with interpersonal interaction. Many previous studies aimed to increase social presence in human-agent interaction, in order to derive users' positive psychological experiences, by applying the factors of interpersonal communication to verbal and non-verbal communication of the agents. This study examined the effects of the exchanges of mutual self-disclosure, one of the most important communication acts in interpersonal communication, between users and interface agents. Users' attachment styles towards the perception of social presence, the evaluations toward the agents, user experiences, and the intentions for future interaction were also studied. The mediating role of social presence in dependent variables was, also, examined in this research. The results showed that exchanging self-disclosures with an agent increased the perceptions of social experience, friendly evaluations toward the agent, positive user experience, and the intentions for future interaction. Participants' attachment styles, also, affected the perceptions of the dependent variables. The effects of the exchanges of self-disclosure and participants' attachment styles were mediated by perceived social presence toward the agent. The findings of this study imply that the social and communicational aspects need to be considered in design of the agents seriously. The results also suggest that there may be differences in the psychological effects of agents on users according to the users' personality.

  • In this study, we investigated age differences of preference and trust ratings when the appearance of an artificial intelligent speaker resembles a human face. The appearance of the artificial intelligent speaker was presented in seven levels from robot face to human face. In addition, face stimuli were divided into gender (male and female) and age (20s / 60s). Participants evaluated the reliability and likability of each face stimulus on a 7-point scale. The results show that younger adults tend to prefer the face that was halfway between the robot and the human face, while older adults evaluated that the perceived reliability and likability were higher when the stimuli resembled the human face. When asked to choose the most preferred of the four face categories, all participants chose a younger face. However, with additional conditions including emoticon face and empty condition, older adults still preferred human face, while younger adults preferred emoticon face and empty condition. Taken together, older adults are more receptive to human faces than robotic faces in the context of artificial intelligence speakers. Because artificial intelligent speakers can play an important role in the elderly living alone, the present study will be a good reference in the design and development of artificial intelligent speakers for the elderly users.

  • Although the Korean Armistice Agreement resulted in complete cessation of the hostilities of the Korean War, it also initiated a rule that obligates Korean men to compulsorily participate in military service. However, psychological factors such as anxiety, stress, and negative perception among the young participants joining the military lead to inefficiency in training and performance. Several types of media production companies have been tasked to deal with this problem. However, their tools have not adequately addressed the root causes of the psychological distress. Stress rates are still high among the youth. This paper offers a method of reducing anxiety and psychological stress among those joining the military. It also aims to help improve concentration and cope with the pessimism of military life. The study measured the increase in concentration as well as the changing rate of anxiety and psychological stress in the participants of two experimental groups. A significant result with t = 2.487, p = 0.042, and 95% confidence levels was revealed by analyzing the data pertaining to the experimental group that was directly exposed to the sensorimotor rhythm (SMR) wave implying that this brain wave alleviated feelings of anxiety and psychological stress. The method proposed in this paper can thus be applied to mitigate stress in soldiers and help them with their personal and military lives. Further interdisciplinary experiments examining the associations between the electrocardiogram and electroencephalogram are required.

  • The gist of a scene can be identified in less than 100msec, and violation in the gist can influence the way to allocate attention to the parts of a scene. In other words, people tend to allocate more attention to the object(s) inconsistent with the gist of a scene and to have better memory of them. To investigate the effects of contextual consistency on the attention allocation and object memory, two experiments were conducted. In both experiments, a $3{\times}2$ factorial design was used with scene presentation time(2s, 5s, and 10s) as a between-subject factor and object-background contextual consistency(consistent, inconsistent) as a within-subject factor. In Experiment 1, eye movements were recorded while the participants viewed line-drawing scenes. The results showed that the eye movement patterns were different according to whether the scenes were consistent or not. Context-inconsistent objects showed faster initial fixation indices, longer fixation times, more frequent returns than context-consistent ones. These results are entirely consistent with those of previous studies. If an object is identified as inconsistent with the gist of a scene, it attracts attention. Furthermore, the inconsistent objects and their locations in the scenes were recalled better than the consistent ones and their locations. Experiment 2 was the same as Experiment 1 except that a dual-task paradigm was used to reduce the amount of attention to allocate to the objects. Participants had to detect the positions of the probe occurring every second while they viewed the scenes. Nonetheless, the result patterns were the same as in Experiment 1. Even when the amount of attention to allocate to the scene contents was reduced, the same effects of contextual inconsistency were observed. These results indicate that the object-background contextual consistency has a strong influence on the way of allocating attention and the memory of objects in a scene.

  • The purpose of this study is to examine the determinant factors of maintaining employment in young adults with intellectual disabilities who took part in a vocational training program and was employed. The determinant factors were from four areas, such as physical competence, job-related task performance, emotional behaviors, and functional adaptive behaviors. 64 young adults with intellectual disabilities participated in this study. The participants' capacities were examined during the program, and then their job retention was examined through a follow-up survey six month after the end of the program. Tests contained hand dexterity, grasp strength, finger strength, visual-perception, Survey of Functional Adaptive Behaviors, and Observational-Emotional Inventory-Revised. After data collection, the data were analyzed by binary logistic regression. The results indicated that dexterity in both hands (OR= 1.123) in physical competence, anxiety (OR= .733) and socialization (OR= .429) in emotional behaviors, and academic skills (OR= 1.077) and vocational skills (OR= 1.542) in functional adaptive behaviors were significant determinant factors. These significant factors which affected job attention were consistent with the results from previous studies, and should be considered when designing and constructing an effective career and vocational education program for young adults with intellectual disabilities.

  • Objectives : The aim of this study was to investigate the characteristics of Hwa-Byung(HB) patients, draw the clinical key issue of HB, and provide the data as the basis for development of Clinical Guideline of HB. Methods : The study participants included 151 subjects who thought they have HB in 9 site. For all patients, we used HB epidemiologic study protocol, which include the Korean version of the Structured Clinical Interview for the DSM-IV Diagnosis (SCID-1), diagnostic criteria of HB, symptoms check list, pattern identification tool, psychiastric psychological questionaires, and Framingham coronary risk score(FRS). Results : 1. For all participants, 62 % of subjects were diagnosed with HB. These patients had comorbid DSM-IV diagnoses with depression (65%) and anxiety (27%). But 22% of these patients had only HB. 2. HB patients had various physical symptoms when visiting, were diagnosed as various disease, and undergone medical treatments in the past. Among the diagonsed illness, Gastronitestinal diseases (51.6%), psychiatric disorders(40.9%), endocrine diseases(39.8%) were being the most frequent. The frequent physical symptoms of HB patients reported were chest discomfort, head ache, pallpitation, frequent sigh, amnesia, shoulder pain, dry mouth, eye fatigue etc. 3. HB patients had high scores in psychologic questionares, CES-D, STAI, and STAXI. It means that HB patients might be low-level emotional stability. 4. Participant had negative opinion about the treatment of HB that it would be difficult or impossible (65.7%), but they neglect the need of medical treatment. Conclusions : This result shows that HB is comorbid with various psychiatric disease, but it has different physio-psychological symptoms from others and there were only HB patients. so we identify HB is independent disease. Moreover, there were the wrong perception of HB which blocking treatments. These problems support that the neccesity of development of Clinical Guideline of HB.

  • The purpose of this study was to investigate how to develop of pre-service childcare teachers' perception about the image of childcare center teachers and self-image. In this study, participants' self-analysis method and in-depth interview were adopted to analyze the aspects of pre-service teachers' teacher image. Also, the narrative of pre-service teachers' a famous painting analysis were reported. The results of this study were divided into nine categories. Findings indicated that participants' self-image analysis work made pre-service teachers more enabled them to expend the significance of teacher's image of role in relation to their career decision and future their teacher's job. Moreover, through the experience of self-analysis work the pre-service teachers recognize their own ability to build up unique and healthy image. To foster the ability of pre-service teachers' self- image, special class teaching methods for pre-service teachers should be developed focusing on evoking them to have more positive self-image. This study suggested that self-image analysis work experiences should be emphasized in university class for pre-service teachers.
