There are two modes to display panoramic movies in virtual reality (VR) environment: non-stereoscopic mode (2D) and stereoscopic mode (3D). It has not been fully studied whether there are differences in the activation effect between these two continuous display modes on emotional arousal and what characteristics of the related neural activity are. In this paper, we designed a cognitive psychology experiment in order to compare the effects of VR-2D and VR-3D on emotional arousal by analyzing synchronously collected scalp electroencephalogram signals. We used support vector machine (SVM) to verify the neurophysiological differences between the two modes in VR environment. The results showed that compared with VR-2D films, VR-3D films evoked significantly higher electroencephalogram (EEG) power (mainly reflected in α and β activities). The significantly improved β wave power in VR-3D mode showed that 3D vision brought more intense cortical activity, which might lead to higher arousal. At the same time, the more intense α activity in the occipital region of the brain also suggested that VR-3D films might cause higher visual fatigue. By the means of neurocinematics, this paper demonstrates that EEG activity can well reflect the effects of different vision modes on the characteristics of the viewers' neural activities. The current study provides theoretical support not only for the future exploration of the image language under the VR perspective, but for future VR film shooting methods and human emotion research.

Journal of Dental Anesthesia and Pain Medicine 2019;19(4):227-233
BACKGROUND: Dental anxiety in children is a major barrier in patient management. If dental anxiety in pediatric patients is assessed during the first visit, it will not only aid in management but also help to identify patients who are in need of special care to deal with their fear. Nowadays, children and adults are highly interested in multimedia and are closely associated with them. Children usually prefer motion pictures on electronic devices than still cartoons on paper. Therefore, this study was conducted to evaluate a newly designed scale, the animated emoji scale (AES), which uses motion emoticons/animojis to assess dental anxiety in children during their first dental visit, and compare it with the Venham picture test (VPT) and facial image scale (FIS). METHODS: The study included 102 healthy children aged 4–14 years, whose dental anxiety was measured using AES, VPT, and FIS during their first dental visit, and their scale preference was recorded. RESULTS: The mean anxiety scores measured using AES, FIS, and VPT, represented as mean ± SD, were 1.78 ± 1.19, 1.93 ± 1.23, and 1.51 ± 1.84, respectively. There was significant difference in the mean anxiety scores between the three scales (Friedman test, P < 0.001). The Pearson's correlation test showed a very strong correlation (0.73) between AES and VPT, and a strong correlation between AES and FIS (0.88), and FIS and VPT (0.69), indicating good validity of AES. Maximum number of children (74.5%) preferred AES. CONCLUSION: The findings of this study suggest that the AES is a novel and child-friendly tool for assessing dental anxiety in children.

Scratching is a main behavioral response accompanied by acute and chronic itch conditions, and has been quantified as an objective correlate to assess itch in studies using laboratory animals. Scratching has been counted mostly by human annotators, which is a time-consuming and laborious process. It has been attempted to develop automated scoring methods using various strategies, but they often require specialized equipment, costly software, or implantation of device which may disturb animal behaviors. To complement limitations of those methods, we have adapted machine learning-based strategy to develop a novel automated and real-time method detecting mouse scratching from experimental movies captured using monochrome cameras such as a webcam. Scratching is identified by characteristic changes in pixels, body position, and body size by frame as well as the size of body. To build a training model, a novel two-step J48 decision tree-inducing algorithm along with a C4.5 post-pruning algorithm was applied to three 30-min video recordings in which a mouse exhibits scratching following an intradermal injection of a pruritogen, and the resultant frames were then used for the next round of training. The trained method exhibited, on average, a sensitivity and specificity of 95.19% and 92.96%, respectively, in a performance test with five new recordings. This result suggests that it can be used as a non-invasive, automated and objective tool to measure mouse scratching from video recordings captured in general experimental settings, permitting rapid and accurate analysis of scratching for preclinical studies and high throughput drug screening.

Korean Journal of Medical Education 2019;31(4):319-330
PURPOSE: The purpose of this study is to explore what the students experienced in short filmmaking class performed to 1st grade premedical students of a medical school, and to trace educational effects of the class. METHODS: Taking a qualitative approach, the authors used semi-structured interviews to collect the data. This study employed the quota sampling method to purposefully select students to interview. Data coding and analysis were performed based on the grounded theory. The filmmaking experiences consistently described by the interviewees were labeled and reorganized into categories through the open, axial, and selective coding. RESULTS: The students experience the group filmmaking class as a participatory class. Learners also experienced the procedure of performing complicated group tasks according to detailed and scheduled processes. Participation leads to collaboration. Collaboration here is through communication and participation, not through mechanical cooperation. Students also experience various dimensions of communication. The students learned that successful performance of the group filmmaking process is enabled through consideration towards others, and experience a sense of connectedness resulting in a type of community spirit. Having fun and interest, finally, the students experience the sense of accomplishment and sharing through joint screening. CONCLUSION: Students' shared experiences and their education effects of the filmmaking class can be explained in terms of the above mentioned seven closely intertwined categories. In this class, the students were able to express emotions they would not normally express. Through this, the students were able to find the true character and new aspects of their fellow students, forming intimacy, which led to a sense of belonging and connectedness.

5.Virtual Reality in Endoscopic Sinus Surgery and Facial Plastic & Reconstructive Surgery.
Korean Journal of Otolaryngology - Head and Neck Surgery 2018;61(5):227-234
With the recent development of information and communication technology, social interest in virtual reality (VR) is increasing rapidly. VR technology is expanding into applications such as games, movies, entertainment, healthcare, education/media, manufacturing, and construction. In the healthcare, VR is used for surgical training, medical education, rehabilitation medicine, pain control, and treatment for psychiatric disorder, but the market size of VR in healthcare is not big compared to VR application in other industries. However, as the demand for high-quality medical care increases and the training time of the resident physicians is reduced, the demand for VR in the healthcare is expected to increase rapidly. Especially, the nose and paranasal sinus are composed of complicated osseous structures, which makes it difficult to understand the exact anatomy and requires highly skilled techniques to perform accurate and safe surgery. For this reason, nose and sinus are a suitable field to apply VR technology. In this review article, we describe the overview of VR technology used in healthcare, the status and prospects of VR in endoscopic sinus surgery and facial plastic surgery.

Journal of the Korean Ophthalmological Society 2018;59(3):230-237
PURPOSE: The blue light emitted from electronic devices may be harmful to the eye. We investigated whether internet-protocol television (TV) with lowered blue light emission reduced ocular fatigue. METHODS: A total of 98 healthy subjects were recruited. They watched an animated movie (A) and an identical version except for reduced blue light (B), sequentially for 1 hour in random order. Before and after watching the movies, we measured the distance and near refraction and tear break-up time objectively. Ocular discomfort score and the earliest onset time of the ocular fatigue symptoms were also measured using our specially designed subjective ocular discomfort scale. RESULTS: The median age of the participants was 28.5 years, and there were 56 females out of 98 total participants. Both distance and near refraction were not significantly different before versus after watching the movies, nor between viewing movies A and B. However, the accommodative amplitude measured by subtracting the near refraction from the distance refraction was found to be greater after watching movie B compared with movie A in a subset of subjects with hyperopia [1.92 vs. 1.72 diopters (D) for the right eye and 2.14 vs. 1.83 D for the left eye; p = 0.04 and p < 0.01, respectively]. The ocular discomfort score was lower (15.40 vs. 12.85; p = 0.10), but not significantly, and the earliest ocular fatigue onset time was significantly delayed (23.48 vs. 34.51 minutes; p < 0.01), after watching movie B. CONCLUSIONS: Reduction of blue light emission alleviated ocular fatigue caused by TV displays. Watching TV with lower blue light may provide benefits to hyperopic individuals by reducing eye strain and improving the accommodative amplitude.

7.Hermeneutic Phenomenological Study on Caring Experience of Spouses of Elderly People with Dementia at Home.
Journal of Korean Academy of Nursing 2017;47(3):367-379
PURPOSE: This study aimed to understand and describe the caring experiences of spouses of elderly people with dementia. METHODS: The hermeneutic phenomenological method was used and participants were 12 spouses aged 65 and over who were taking care of their husbands or wives with dementia at home. Data were collected from individual in-depth interviews on participants' actual caring experiences. Additionally, novels, movies, and memoirs on elderly couples with partner who had dementia were included as data for the analysis. The qualitative data analysis software program was used to manage and process the collected qualitative data. Data were analyzed using hermeneutic phenomenological analysis based on four fundamental existentials including lived body, lived space, lived time, and lived others. RESULTS: Five essential themes emerged from the analysis: 1) body moving like an old machine, 2) swamp of despair filling with hope, 3) sweet time after bitterness, 4) disappointed elderly couple in the empty nest, and 5) unappreciation vs. empathetic feelings. These essential themes were comprehensively summarized as “the road leading to the maturation of life with dedication and hope while bearing the weight of caring based on the couple's relationship.” CONCLUSION: The findings indicate that the nature of the caring experience of spouses of elderly individuals with dementia is filled with many dynamic and paradoxical dimensions. Thus, results of the study would help with developing interventions tailored specifically for elderly spouse caregivers to support their role adaptation and ultimately improving their quality of life.

8.The Effect of a Movie-Based Nursing Intervention Program on Rehabilitation Motivation and Depression in Stroke Patients.
Journal of Korean Academy of Nursing 2017;47(3):345-356
PURPOSE: The aim of this study was to develop and measure the effect of a movie-based-nursing intervention program designed to enhance motivation for rehabilitation and reduce depression levels in stroke patients. METHODS: The study used a quasi-experimental, nonequivalent control group and a pretest-posttest design. The 60 research subjects were assigned to the experimental (n=30) or control group (n=30). The movie-based nursing intervention program was provided for the experimental group during 60-minute sessions held once per week for 10 weeks. The program consisted of patient education to strengthen motivation for rehabilitation and reduce depression, watching movies to identify role models, and group discussion to facilitate therapeutic interaction. RESULTS: After 10 weeks of participation in the movie-based nursing intervention program, the experimental group's rehabilitation motivation score was significantly higher, F=1161.54 (within groups df=49, between groups df=1), p<.001, relative to that observed in the control group. In addition, the experimental group's depression score was significantly lower relative to that observed in the control group, F=258.97 (within groups df=49, between groups df=1), p<.001. CONCLUSION: The movie-based nursing intervention program could be used for stroke patients experiencing psychological difficulties including reduced motivation for rehabilitation and increased depression during the rehabilitation process.

Korean Journal of Women Health Nursing 2017;23(4):287-298
PURPOSE: The purpose of this study was to deepen understanding the nature of the care experience by the mothers with adult children in persistent vegetative state. METHODS: Participants were 7 mothers caring for their adult children in persistent vegetative state. Data were collected individually through in-depth interviews on their lived experiences. Also texts were included as data from literary works, novels, movies, essays, and arts containing on patients with persistent vegetative state and their mothers. Data were analyzed by van Manen's phenomenological methodology. RESULTS: The essential themes of caring experiences of the mothers were as follows. The theme in relation to lived time has shown as back to the past and caring experience related lived body has emerged as locked the body in children. The theme related lived space was getting into the swamp and the theme in lived others was derived as lonely struggle into. CONCLUSION: The nature of mothers' caring experiences for adult children in persistent vegetative state is summarized as ‘Do not off hand of hope in a locked state’. This study suggests long-term supports are necessary for mothers to care persistent vegetative state children.

10.YI Kwang Su's Love and history records of modern hospital under the japanese colonial period.
Korean Journal of Medical History 2016;25(3):407-444
This article aims to evaluate and analyze the description of the modern hospital as history record, which appeared in YI Kwang Su's novel Love. This novel has mentioned in detail western style clinic, Bukgando Catholic hospital, tuberculosis sanitarium as its main space. Modern hospitals are depicted in the novel has a great significance in historical aspect as well as in literary aspect. The most data on modern hospital is laws, statistics and newspaper archives. These materials are a great help to understand the history and status of the modern hospital. Literary description here is important materials, that specific to reconstruct the appearance of the modern hospital at that time. Literary representations infuse life into the history record. In this regard, Love has special meaning in the history of Korean modern literature. Before anything else, doctor AN Bin's clinic as a first space of the novel vividly shows the reality of the Western style clinic and a general practitioner under the colonial period. The establishment of the hospital was based on ⌜Rules on private hospital⌟ declared by the Japanese Government General of Korea in 1919. According to this Rules, a private clinic's founder had to submit the documents to the director of police affairs, in which all the details were written. It included name of hospital, site location and size, floor plan of a nearby building, each size of patient's rooms, number of steps and emergency exit, bath, toilet, disinfecting room. AN Bin's clinic was a private hospital with the requirements in the rules. The descriptions of this clinic re-created real situation of private hospitals, specifically scale of hospital, interior space, conditions of patient's room at the time. The second modern hospital in the novel is Bukgando Catholic hospital. There is a lot more materials on medical activity and hospital of protestant churches than we thought. But we do not have a lot of information on catholic church's medical activities and hospital. In this respect, Bukgando Catholic hospital in Love has a great value as historical material. The medical activity of catholic churches was weak than protestant's one under the japanese colonial period. But there were catholic church's medical activities and hospitals. The catholic church's professional medical activities are mainly deployed since the 1930s in earnest, especially Bukgando Catholic hospital played an important role. The catholic hospital in this novel is valuable material to understand medical activities of catholic church. Third form of the modern hospital described in the Love is tuberculosis sanitarium. WADA Tomomi maintained that the model of Bukhan sanitarium was Kyeongseong sanitarium, that was established by the seventh-day adventist in 1936. She thinks, that the adventist church's treatment is similar to Bukhan sanitarium's. The therapy of the adventist church, however, was common from tuberculosis treatment at the time and AN Bin was not adventist. And WADA Tomomi said that ‘ozone’ therapy of Bukhan sanitarium came from Kyeongseong sanitarium. But we can find this therapy in Haeju sanitarium. In this respect, AN Bin's sanitarium is similar to Haeju sanitarium. YI Kwang Su had not modeled his Bukhan sanitarium on certain sanitarium. He had integrated the materials on sanitarium and envisioned Bukhan sanitarium. Here Haeju sanitarium played important role than Kyeongseong sanitarium. In conclusion, Love has a special meaning as an important historical material, that restore and understand the history of the modern hospital. Literature is worth as a record of the society. In particular, novel infuses human breath into the history record, as if we can see the motion picture.
