Under the the coronavirus disease 2019 (COVID-19) pandemic, it is important to achieve two goals, protecting inpatients from infection and providing appropriate psychiatric treatment for psychiatric emergency patients, including those at an acute psychiatric stage. This paper proposes improvement measures by understanding the status and problems of the psychiatric emergency of South Korea. The confirmed definition of psychiatric emergency from the perspective of the current policy of the Ministry of Health and Welfare, legal regulations, and medical practice was used. The status of psychiatric emergencies from related statistical data was estimated, and the related problems were summarized. First, a data system for the current state of psychiatric emergencies in South Korea is needed. Second, specialized medical resources are needed considering the severity of psychiatric symptoms and COVID-19 infection. Lastly, efforts are needed to secure insufficient medical resources and expand the psychiatric emergency system. South Korea requires the establishment of a psychiatric emergency service system at the national level to overcome the pandemic situation in 2020 and fix pre-existing problems before the COVID-19 pandemic.

The aim of this study is to classify the information that motion and haptic effects of 4D cinema seat describe. 4D technology can add physical effects such as motion, vibration, and wind to audiovisual contents, enabling users to have more realistic and immersive experiences. Specifically, it is known that motion and haptic effects can improve an audience’s immersion. The information that motion and haptic effects describe should be explored to systematically design audience-friendly effects. Eight graduate students in the field of user experience or haptics participated in the experiment. They observed what motion and haptic effects of a 4D cinema seat describe and wrote them in a note while watching five 4D films. After watching each 4D film, they had a discussion and classified the effects based on the information the effects describe. The motion and haptic effects were classified into four categories: object movement, camera viewpoint, sound, and circumstances. The classification would be useful to plan systematically user experience studies of 4D effects. The results of this study might also help to provide design insights to the 4D effect designers.

The purpose of this study is to develop an emotional vocabulary classification which covers a broad range of emotions for better emotional assessment. Previous studies classified only the emotional words reported from precedent research and thus suggested an emotional vocabulary classification contained few subdivided emotions. There might be limitations in the emotion analysis or accurate emotion recognition when using the existing classification. We collected emotional words from a Korean dictionary as well as from previous studies, and classified them using the open card sorting method to establish a more extensive and subdivided Korean emotional vocabulary classification. As a result, 436 words were collected and the classification consisted of 3 categories, 13 sub-categories and 40 sub-sub-categories. It is expected that the classification will be useful in developing questionnaires or planning experimental designs for emotion assessment, and helping researchers analyze users’ emotions more specifically and accurately.

Objective : A pilot project entitled '50s mental health screening project' was conducted in Seoul. As a part of this project, we conducted surveys to obtain the opinions of psychiatrists regarding mental health screenings. Methods : A questionnaire was mailed to members registered with the Korean Neuropsychiatric Association, which enquired about the '50s mental health screening project'. Results: A majority (90.9%) of the subjects agreed on the purpose and implementation of the project. However, there were fewer individuals that actually showed the intent to participate (65.8%). The mean age of the group with the intention to participate was higher compared to the group with no intention to participate. The factors that negatively affected the intent to participate included prejudice and discrimination against psychiatry (3.795), low health insurance reimbursement (3.784), and inconvenience of reporting to public health centers (3.664). The most appropriate method that scored the highest for screening mental health was face-to-face consultation with a psychiatrist (3.889). Most of the participants agreed on the method of a self-reported survey along with an interview of psychiatrist (84.9%). Conclusion : Subjects were concerned about prejudice and discrimination against psychiatry, low health insurance reimbursement, and inconvenience of reporting to public health centers. These problems need to be supplemented. Face-to-face consultation with a psychiatrist may be considered an appropriate method for future mental health screening.

Metal matrix composites had generated a lot of interest in recent time because of their high specific strength and stiffness in specific properties. It was also highlighted as the material of frontier industry because strength, heat-resistance, corrosion-resistance and wear-resistance were superiored. In this study, the strength properties of AI18B4O33/AC4CH composites were represented mixing the binder of SiO2. It was also fabricated by squeeze casting. AI_18B_4O_33/AC4CH was fabricated at the melt temperature of 760℃, the perform temperature of 700℃ and mold temperature of200℃ under the pressure of 83.4MPa. Consequently, fatigue life was observed roughly in the order of AC4CH) nobiner) SiO_2, independently on crack propagation direction and stress ratio.<br/>
