Objectives The eye movement (EM) has been reported to play a role in enhancing the retrieval of episodic memories and reducing effects of fearful episodes in the past and worries for the futures. However, it is still unclear in the mechanism of EM in normal subjects. We examined the horizontal eye movement (HEM) effect using an aiding apparatus on mental health indices including negative and positive psychological factors, and psychophysiological measures such as heart rate variability and quantitative electroencepaholography (qEEG) in healthy subjects. Methods Twenty eight healthy subjects were recruited and randomly allocated into two groups : active HEM group and control group. The active HEM group conducted the HEM training with usual stress management audio-intervention using the apparatus inducing eye movement once a day for 14 days. The control group also conducted the same training once a day for 14 days, however, the saccadic eye movement was not included in this training. Psychological measurements, neurocognitive function tests, heart rate variability measurement and qEEG were conducted before and after the training in both groups. Results In the active HEM group, sleep status using Sleep Quality Scale (SQS) positive factors significantly increased after the training. By contrast, scores on the negative items of Psychological Well-Being Scale (PWBS), and negative items of the Life Orientation Test-Revised (LOT-R) were significantly decreased after the training. The percentage of delta amplitude (1-3 Hz) in qEEG significantly decreased after the HEM training. The percentage of alpha amplitude (8-12 Hz) significantly increased after HEM training. The change of delta amplitude in the active HEM group was positively correlated with the change of sleep satisfaction of Visual Analogue Scale (VAS), and the change of alpha amplitude was negatively correlated with depression of VAS, anxiety of VAS and Beck Anxiety Inventory (BAI). Conclusions The HEM training improved sleep quality and well-being, and sense of optimism. The HEM training also increased alpha amplitude and decreased delta amplitude in qEEG. The qEEG changes were well correlated with subjective improvement of mental health indices in healthy subjects. These results suggest some evidences that HEM training using the apparatus that induces EM would be helpful in improving subjective mental health in healthy subjects. Further study with larger samples size would be needed.
Unlike adults, cognitive ability and communication are not accurate in pediatric patients. Therefore movement due to psychological anxiety in X-ray photography is one of the factors that increase repeated irradiation. In order to minimize the rejection of X-ray and to improve the satisfaction of medical service, it is necessary to improve the environment of the radiological room to help psychological stability and to find a positive measure for reduction of radiation dose, including unnecessary. The subjects of this study were 186 pediatric patients from May to July, 2017, who were from 6 months to 36 months, The study group was set up a radiological room without auditory and visual environment changes is A group, except for changes in visual environment, the room where only auditory environmental changes were applied was group B, the auditory environment changes were excluded, and the room where only the visual environment change was applied was divided into group C, the auditory and visual environment changes were applied to the D. In group A, 10 retrospectives were obtained, 7 in group B, 5 in group C, and 2 in group D. Especially in group A and group D, statistically significant at p <0.053 In conclusion, hearing and visual environment changes affected the psychological stability of pediatric patient, and the repeated irradiation was reduced, thus improving the quality of medical services.
The objectives of this study were to investigate physiological and psychological responses to the rustling sound of Korean traditional silk fabrics and to figure out objective measurements such as sound parameters and mechanical properties determining the human responses. Five different traditional silk fabrics were selected by cluster analysis and their sound characteristics were observed in terms of FFT spectra and some calculated sound parameters including level pressure of total sound (LPT), Zwicker's psychoacoustic parameters - loudness(Z), sharpness(Z), roughness(Z), and fluctuation strength(Z), and sound color factors such as ${\Delta}L\;and\;{\Delta}f$. As physiological signals, the ratio of low frequency to high frequency (LF/HF) from the power spectrum of heart rate variability, pulse volume (PV), heart rate (HR), and skin conductance level (SCL) evoked by the fabric sounds were measured from thirty participants. Also, seven aspects of psychological state including softness, loudness, sharpness, roughness, clearness, highness, and pleasantness were evaluated when each sound was presented. The traditional silk fabric sounds were likely to be felt as soft and pleasant rather than clear and high, which seemed to evoke less change of both LF/HF and SCL indicating a negative sensation than other fabrics previously reported. As fluctuation strength(Z) were higher and bending rigidity (B) values lower, the fabrics tended to be perceived as sounding softer, which resulted in increase of PV changes. The higher LPT was concerned with higher rating for subjective loudness so that HR was more increased. Also, compression linearity (LC) affected subjective pleasantness positively, which caused less changes of HR. Therefore, we concluded that such objective measurements as LPT, fluctuation strength(Z), bending rigidity (B), and compression linearity (LC) were significant factors affecting physiological and psychological responses to the sounds of Korean traditional silk fabrics.

Background: Body image dissatisfaction among breast cancer survivors has been associated with psychological stress resultant from breast cancer and resultant surgery. This study aimed to examine the psychometric properties of the Malay Version of the Breast-Impact of Treatment Scale (MVBITS) and to investigate the associations of retained factors with the Hospital Anxiety and Depression Scale (HADS) and the Rosenberg Self-Esteem Scale (RSES). Materials and Methods: The MVBITS was 'forward-backward' translated from English to Malay and then administered to 70 female breast cancer patients who came to the Oncology Clinic of University Malaya Medical Centre, Kuala Lumpur, Malaysia to undergo chemotherapy. Principal component analysis (PCA) with varimax rotation was performed to explore the factor structure of the MVBITS. Associations of retained factors were estimated with reference to Spearman correlation coefficients. Results: The internal consistency reliability of MVBITS was good (Cronbach's alpha 0.945) and showed temporal stability over a 3-week period. Principal component analysis suggested two factors termed as 'Intrusion' and 'Avoidance' domains. These factors explained 70.3% of the variance. Factor 1 comprised the effects of breast cancer treatment on the emotion and thought, while Factor 2 informed attempts to limit exposure of the body to self or others. The Factor 1 of MVBITS was positively correlated with total, depression and anxiety sub-scores of HADS. Factor 2 was positively correlated with total and anxiety sub-scores of HADS. MVBITS was also positively correlated with the RSES scores. Conclusions: The results showed that the Malay Version of Breast-Impact of Treatment Scale possesses satisfactory psychometric properties suggesting that this instrument is appropriate for assessment of body change stress among female breast cancer patients in Malaysia.
We studied in order to find out suitable amounts of board by visual effects to establish indoor boards and human psychological effects by several board designs. Thirty students of C university were tested in constant temperature/humidity room and interviewed after tests. The experimental visual images were projected from 54' TV. As a result, the board length that showed high preference and satisfaction was the 90cm both horizontal and vertical direction. We found that vertical board gave an impression of a linear and narrow shape and the horizontal board gave wide space and cool feeling from psychological analytical study. The factors affecting satisfaction in horizontal direction were refreshing, intimacy, beauty, area, splendor and those in vertical direction were a sense of security, beauty, texture, intimacy, continuity, extensity, natural feeling. We got 5 factors from the result of factor analysis in order to get psychological factor axis. Those were pleasantness, artificiality, openness, dynamics, refinement. By multiple regression analysis, the factor pleasantness had the highest impact on visual satisfaction on scenary. The study on psychological factor difference by analysis of variance showed that psychologically feeling amount about pleasantness, artificiality, dynamics, refinement, and openness had statistically meaningful difference despite of board direction. We found that the 90cm had a tendency as a changing point leading image change by the investigative analysis of board direction based on factor points.
The present study is designed to explore psychological correlates of career barrier of female college students in engineering fields by investigating psychological characteristics of female students and by comparing them with those of male students. For these ends 1,968 female and male students in 8 universities nation-wide completed the questionnaire which includes the measures for self career aspiration, self-efficacy, satisfaction and expectation in engineering career. The results of our study revealed female students scored significantly lower than male students in all of these variables. In addition, the developmental patterns of female and male students differ significantly; Male students aspiration, self-efficacy, expectation and satisfaction increased with the school experience whereas those of female students did not show any change or decrease. The results call for the intervention to improve the psychological vulnerability of female students in engineering field.
This study was performed to investigate main psychological phenomena and healing process through qualitative analysis on the 115 handwriting healing experience in the forest. Main psychological phenomena experienced in the forest were important in order happiness, comfort, and understanding. The process of healing in the forest was first characterized by emotional changes, and was led to cognitive changes and behavioral changes. Healing stage of the forest has followed with six steps of stimulus, accommodating, purification, insight, filling, and change. This process was associated with nature sympathetic, rapport with oneself, and with the world. Previous studies, which were focused on the measurement of transient state after the comparative study between control and experimental groups, could not verify the continuity and process of psychological healing. this study suggests a new approach to understand the subjective psychological phenomena and healing processes in the forest, and will be a basis for developing and performing of forest healing program.

Purpose: This study aims to assess the psychological characteristics of patients with iatrogenic damage of the trigeminal nerve using Symptom Checklist-90-Revised (SCL-90-R). Methods: A total of 22 patients who visited the clinic of Department of Oral Medicine, School of Dentistry, Chosun University were evaluated in the months from December 2012 to December 2014. Patients were included in the study if they presented with reported sensory changes due to iatrogenic trigeminal nerve injury. A total of 37 control group who has no symptoms of pain and sensory change were included in the study. All participants filled out the SCL-90-R instrument to assess psychosocial symptoms. Results: The T-scores of most of the SCL-90-R symptom dimensions were within normal range (less than 55) in the patients and the control group. The patients group showed higher T-scores of SCL-90-R than those of the control group, with statistically significance of somatization, anxiety, psychoticism, and positive symptoms distress. Female patients group had higher Tscores of SCL-90-R than those of male patients group, but there was no statistical difference, except for the positive symptom global index. The chronic patients group showed higher Tscores of SCL-90-R than those of the acute patients group, but there was no statistical difference, except for the Positive symptom global index. Conclusions: According to the psychological assessment of iatrogenic trigeminal nerve injury patients using SCL-90-R, the patients group, as compared to the control group shows a significantly higher score for somatization, anxiety, and psychoticism. Therefore, assessment of psychological state would be considered to treat patients with iatrogenic trigeminal nerve injury.

With the advent of the Fourth Industrial Revolution, people need healing. Research in neuroarchitecture shows that people feel happy and stable when working with nature, and patients heal quickly. Therefore, This study aims to quantitatively analyze the colors that help psychological healing in the painting images depicting nature by setting 'Natural Colors' of Biophilic Design as the subject of research. So the purpose of this study was to measure Biophilic Color and to develop Biophilic Color Palette. We extracted Biophilic colors using Impressionist Monet's Landscape painting. After extracting colors using Photoshop Color Picker, we converted RGB color code to NCS color code and Munsell color code. The results of this study were as follows; The ratio of Y was high in the GY-series and YR-series. This is due to the characteristic of impressionism that expresses the change of color by light in close relationship with light. Y is universally considered to be pleasant, representing happiness, sunshine and optimism. Therefore, it is possible to create an environment that helps psychological healing by utilizing the Y-series color palette. Average Blackness was 28. Average Chromaticness was 34.61. The significance of this study is to propose a biophilic color palette that is useful for psychological healing by quantifying the color code of biophilic colors depicted and expressed with adjective images and idiomatic color names. Quantitative and empirical studies on healing colors are needed continuously and should be actively utilized in healing environment planning.

The purpose of this study is to rediscover the gestalt psychological value of the Landscaping structure and architectural landscape in the vulnerable village consulted by experts in 2021 year. For this study, nine villages called of Saethul Maul were surveyed, and two of them were analyzed for landscape composing of gestalt psychology. The two villages, Yulwon and Jeonchon, included the case where the landscaping structure of residence was viewed from outside the village and the case from within the village. Psychological distance of the villages is analyzed by D/H ratio for the scenery seen from lanes. There are three expected conclusions. First, in terms of gestalt psychology, the buildings mean a figure, and the rice field in front of the village, the mountains behind the village, and the lanes represent a landscape structure consisting a background(ground). It captures the unique landscape aesthetics of the vulnerable village. Second, the landscape seen in the village shows various differences in horizontal distance and vertical height of the lane, so even if the psychological distance gives a sense of closure, it gives a sense of rhythm and change. However, considering the psychological distance (D/H ratio) when the roads are expanded for the fire car, the village landscape can be re-formed by safety and function. Third, the architectural landscape of Yulwon village is characterized by the harmonious arrangement of traditional houses, Narack-Doiji (rice barn), and wooden building (agricultural barn) in the background of chestnut tree hill behind the village. It is necessary to reduce the use of industrial materials and restore the valuable architectural landscape of the vulnerable village.
