The psychiatric interview is not a random or arbitrary meeting between doctor and patient. It is a systematic attempt to understand the relationship of psychopathology to emotional conflicts in patient, and interviewing is an in rather than a science, a skill that can be acquired but probably not taught. The faculty of the Seoul National University Hospital, Department of Psychiatry, have been providing 12 sessions of seminar on Psychiatric Interview and Psychopathology every year for the first year residents for the past 15 years. The authors presented three cases materials with their understandings of psychopathology and psychodynamics, each of which the authors had performed live interviews for 50 minutes in front of the residents. Those are a young male with conversion disorder whose chief complaints was motor aphasia, a young college girl with paranoid schizophrenia whose chief complaints were persecutory and erotic delusions with auditory hallucination, and a climacteric female in delusional disorder who had a delusion of infidelity. The most frequent questions the residents raised after the presentations were on the significances of the first interview, danger of making the diagnoses with short interviews, and methodology of questionings and not-questionings. In reply the authors discussed the importance of understandings of psychopathology and psychodynamics, the flexibility of the techniques of interviewing, and priority-related matters in which the understanding of psychodynamics proceed to the diagnoses.

VR refers to Virtual Reality technology that allows experiences of virtual contents as if they are real through visual, auditory and other senses. VR is even affecting the news. This greatly shakes the frame of the news. In other words, the conventional way of the new was to watch it with the passive action of seeing pictures, articles and images while VR News offers an active paradigm of experience and participation. This study analyzed the VR news of each press and investigated how VR news is developing. Furthermore, an experimental study was conducted to examine how users actually perceived the VR news. News made using both the existing method and the VR news method were comparatively shown to users who were following the news, and the interview was carried out through questionnaires. The results obtained through the statistics and analysis are as follows. Users made an assessment that they felt the sense of realism in recognition of the VR news while it was still lacking in terms of the unique information delivery that the news performs. However, the intention of using the VR news again was shown to be high, which demonstrated the expectation of users who have experienced the VR news.

Mobility passengers with over four levels of autonomous driving are more likely to feel carsickness because they do not drive independently. Therefore study on how to prevent or mitigate carsickness are needed to ensure comfortable and productive moving experience of passengers. Therefore this study looked into prior researches on the causes and solutions of carsickness and conducted a survey on the specific situation of carsickness among the general public. Based on this preliminary study the four interaction guide lines for preventing and mitigating of carsickness were designed and validated by performing a CVT (Concept value test). The study have shown that people prefer auditory sense and somatic senses for response in carsickness. These current have been similar in CVT and I believe that specific interaction design proposals and validations will be needed in the future.

360VR content requires short latency, such as immediate response to viewers' viewport changes and high quality video delivery. It is necessary to consider efficient transmission that guarantees the QoE(Quality of Experience) of the 360VR contents with limited bandwidth. Several research has been introduced to reduce overall bandwidth consumption by predicting a user's viewport and allocating different bit rates to the area corresponding to the viewport. In this paper, we propose novel viewport prediction scheme that uses sound source location information of 360VR contents as auditory recognition information along with visual recognition information. Also, we propose efficient transmission algorithm by allocating a bit rate properly based on improved viewport prediction. The proposed scheme improves the accuracy of the viewport prediction and provides high quality videos to tiles corresponding to the user's viewpoint within the limited bandwidth.

Human beings have made remarkable advances in medical technology as well as technological advances. However, as was the case in the past, incurable diseases still exist: temporo-mandibular joint (TMJ). The diagnosis of the Korean medical staff, currently called a "medical advance," is adhering to the outdated patient's comments, diagnosis using a doctor's auditory diagnosis and a ruler, and diagnosis of X-ray imaging. Therefore, it is important to have accurate patient symptoms, to have a doctor's own diagnosis and experience, to increase the number of diagnoses due to the severity of the symptoms, and to cover the costs of medical care. To solve this problem, the core conductive signal generated from the bridge was quantified through %MVC. Quantified EMG will be assessed and compared with Cortex to establish a jaw joint condition evaluation criterion.

Background and Objectives: We sought to evaluate the diagnostic and prognostic value of measurable parameters of internal auditory canal (IAC) magnetic resonance imaging (MRI) in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). Subjects and Methods: We retrospectively reviewed the patients with ISSNHL who underwent IAC MRI from January 2008 to March 2019. Measurable parameters of IAC MRI, such as the diameter of the IAC, bony cochlear nerve canal, and cross-sectional area of the cochlear nerve, were measured by a single examiner. These parameters were then compared between the affected and healthy sides. Inner-ear abnormalities such as intralabyrinthine hemorrhage or labyrinthitis were also evaluated. The relationship between the surveyed parameters and the diagnosis of ISSNHL was assessed. Results: A total of 208 patients with ISSNHL were included. The measured parameters of IAC MRI were not different between the affected and healthy sides and were also not associated with the diagnosis of ISSNHL. However, inner-ear abnormalities of IAC MRI in ISSNHL displayed a significant association with worse hearing before and after treatment. An age that was older than 40 years also correlated with poorer outcomes. Further, inner-ear abnormalities were more frequently detected when IAC MRI was performed early after ISSNHL onset. Conclusions: Patients with ISSNHL and inner ear abnormalities such as intralabyrinthine hemorrhage or labyrinthitis identified via IAC MRI may experience poorer hearing outcomes. To detect such abnormal findings, it is recommended to perform IAC MRI early after the onset of ISSNHL.

Background: Office workers experience neck or back pain due to poor posture, such as flexed head and forward head posture, during long-term sedentary work. Posture correction is used to reduce pain caused by poor posture and ensures proper alignment of the body. Several assistive devices have been developed to assist in maintaining an ideal posture; however, there are limitations in practical use due to vast size, unproven long-term effects or inconsistency of maintaining posture alignment. We developed a headphone and necklace posture correction system (HANPCS) for posture correction using an inertial measurement unit (IMU) sensor that provides visual or auditory feedback. Objects: To demonstrate the test-retest reliability and concurrent validity of neck and upper trunk flexion measurements using a HANPCS, compared with a three-dimensional motion analysis system (3DMAS). Methods: Twenty-nine participants were included in this study. The HANPCS was applied to each participant. The angle for each action was measured simultaneously using the HANPCS and 3DMAS. The data were analyzed using the intraclass correlation coefficient (ICC) = [3,3] with 95% confidence intervals (CIs). Results: The angular measurements of the HANPCS for neck and upper trunk flexions showed high intra- (ICC = 0.954-0.971) and inter-day (ICC = 0.865-0.937) values, standard error of measurement (SEM) values (1.05°-2.04°), and minimal detectable change (MDC) values (2.92°-5.65°). Also, the angular measurements between the HANPCS and 3DMAS had excellent ICC values (> 0.90) for all sessions, which indicates high concurrent validity. Conclusion: Our study demonstrates that the HANPCS is as accurate in measuring angle as the gold standard, 3DMAS. Therefore, the HANPCS is reliable and valid because of its angular measurement reliability and validity.

This study suggests multisensory interaction techniques to help visually impaired people appreciate and understand artworks through non-visual senses such as tactile, auditory, and olfactory senses. A user study was conducted on the basis of a qualitative interview about the experience of appreciating artwork through the multisensory interaction system to visually impaired people so as to verify the development of the interaction techniques. The user test shows that the multisensory interactions in artwork generally not only help them appreciate and understand it but also give them satisfaction through artwork appreciation. However, it also indicates that some multisensory interactions caused the visually impaired people confusion and could not be perceived during the appreciation. On the basis of these outcomes, implications in this study are as follows. This study has contributed to providing specific development guidelines and indicators of non-visual multisensory interactions as a technical alternative to improve accessibility to cultural and artistic activities for the visually impaired. Furthermore, this study is expected to contribute to building a technical background, which can provide comprehensive sensory experiences with not only blind people but also non-blind people such as children and the elderly through universal interaction techniques beyond existing visual-oriented fragmentary experience.

The landscape of the current fitness trackers is not only limited to the aerobic exercises but also the weight training is comparatively excluded. Recently, a few weight training fitness tracker was released, human-computer interaction was not well designed due to the lack of considering the context. Because body movement would be intense while doing exercises, having exercise performers hold or operate a device makes a negative experience. As the wearable device is always inseparable to body, it could provide effective feedback because holding or operating a device is not necessary. Therefore, this study aims to make the exercise performers feel a natural feedback through the wearable device to do effective exercises. As a result, this study identified three findings. First, the information which exercise performers most needed was 'during exercise.' and the most necessary information for exercise performers through wearable device's sensory feedback was about 'pace control' with counting and motivation. Second, the order of the most preferred presentation type of sensory feedback was auditory feedback, haptic feedback and visual feedback. Third, the satisfaction, utility, usefulness score of sensory feedback as same as the personal trainer's feedback. In conclusion, this study illustrated the feedback design implications using a wearable device while doing weight training and the possibilities that wearable device could be substitute for personal trainer.
