Mammalian physiology and behavior are regulated by an internal time-keeping system, referred to as circadian rhythm. The circadian timing system has a hierarchical organization composed of the master clock in the suprachiasmatic nucleus (SCN) and local clocks in extra-SCN brain regions and peripheral organs. The circadian clock molecular mechanism involves a network of transcription-translation feedback loops. In addition to the clinical association between circadian rhythm disruption and mood disorders, recent studies have suggested a molecular link between mood regulation and circadian rhythm. Specifically, genetic deletion of the circadian nuclear receptor Rev-$erb{\alpha}$ induces mania-like behavior caused by increased midbrain dopaminergic (DAergic) tone at dusk. The association between circadian rhythm and emotion-related behaviors can be applied to pathological conditions, including neurodegenerative diseases. In Parkinson's disease (PD), DAergic neurons in the substantia nigra pars compacta progressively degenerate leading to motor dysfunction. Patients with PD also exhibit non-motor symptoms, including sleep disorder and neuropsychiatric disorders. Thus, it is important to understand the mechanisms that link the molecular circadian clock and brain machinery in the regulation of emotional behaviors and related midbrain DAergic neuronal circuits in healthy and pathological states. This review summarizes the current literature regarding the association between circadian rhythm and mood regulation from a chronobiological perspective, and may provide insight into therapeutic approaches to target psychiatric symptoms in neurodegenerative diseases involving circadian rhythm dysfunction.

This study investigates sound, scenery, and soundscape preferences, which are sensory factors that users feel in a healing forest, comparing the difference in recovery by the soundscape. In the barrier-free, wooden walking path of the National Daegwallyeong Healing Forest, a survey site with five different conditions was selected. Users prefer water sounds the most and places with open views for scenery. For the complex sensation of soundscapes, the most preferred is a space where water sounds can be heard, and either a waterfall or an open view can be seen. A profile of mood states test was use to compare users' psychological recovery by the soundscape. It was found that users felt the most positive mood with water sounds and open views. In addition, users' preference for artificial sounds, scenery, and soundscape was the lowest. In the mood state test, it was found that the artificial soundscape incited the most negative emotions.

Body positivity has emerged among young social media users with the purpose of enhancing a positive body image. In the social media environment, body positivity is frequently presented in the forms of female models' images and/or words that represent individual attitudes toward the female body. The media effects on female viewers' body image differs based on the viewers' perceptions of their own body size. This experimental study examined how body positivity and types of expression on social media influence women's mood and appearance satisfaction by subjective body size. We randomly assigned to 415 young and middle-aged females to one of six experimental conditions which contained three images and three vignettes, each reflecting non-body positivity, body positivity, and control. We used a 3 (body positivity: non-body positivity vs body positivity vs. control) × 2 (types of body positivity expression on media: images vs vignettes) × 2 (subjective body size: under/normal weight vs overweight/obese) between-subject design. The results of MANCOVA revealed the significant main effects of subjective body size on women's mood and appearance satisfaction. There was a significant interaction effect of body positivity and subjective body size on appearance satisfaction. The stimuli representing body positivity caused positive psychological effects for women who perceive themselves being in the under/normal weight range.

Occupants' visual perception, psychological responses and spatial satisfaction under various indoor lighting environments were analyzed in this study. Field measurements and surveys were conducted in four coffeeshop space where different lighting conditions were used. Results imply that worse visual comfort was reported under direct lighting conditions that exposed light sources to occupants. To improve spatial satisfaction in space, lighting environments should lessen visual thresholds and distraction. Also, necessary illuminance levels should be kept with appropriate color of light that occupants prefer. Worse spatial satisfaction was reported under direct lighting environments, and spatial satisfaction was strongly relevant to visual comfort. Psychological comfort for space was positive in space where visual thresholds were minimized and visual comfort was positively evaluated. Psychological and spatial satisfaction was relevant each other. Occupants preferred to stay longer in space where psychological and spatial satisfaction was positively achieved due to less visual thresholds and improved visual comfort. Better psychological and spatial satisfaction was achieved in space where temporary mood and visual perception were favorably evaluated under indirect lighting environments.

이 글에서 논자는 오늘날 불안의 실존적 현상들을 살펴봄으로써 불안의 진단과 치료에 있어서 철학적 근거를 드러내보고자 한다. 특히 불안의 근원을 심리적 차원과 더불어 윤리적 차원을 통해 살펴봄으로써 심리적 현상으로서 불안의 철학적 근거를 강조하고자 한다. 이를 위해 가능성과 현실성 '사이존재(Zwischesein)'로서 실존 그리고 존재의 분열과 봉합 사이의 순간이 수반하는 '사이기분(Zwischenstmmung)'으로서 불안을 드러낸다. 불안의 근거로서 실존이 지닌 '사이성(Zwischeheit)'에 대한 주목은 키에르케고어($S{\ddot{o}}ren$ Kierkegaard)에 의해 '종합' 개념 속에서 나타지만 '두 개 사이의 관계'로서 그의 종합 개념은 오히려 종합이라는 용어로 인하여 충분히 주목되지 못했다. 논자는 사이성에 대한 조명을 통하여 실존 개념이 지니는 보다 심층적 조건을 포착해본다. 그리하여 논자는 분열된 양자 사이의 종합이라는 결과보다는 그 양자 사이의 긴장이라는 과정에 주목해본다. 이 를 위해 실존철학의 선구자인 키에르케고어의 "불안의 개념"을 분석한다.

Objectives : Insufficient sleep could have harmful effects on mental health. We examined the mental health status of Korean adolescents according to daily sleep time and subjective sleep satisfaction using a nationwide representative sample of Korean adolescents. Methods : Data from the 2016 Korean Youth Risk Behavior Web-based Survey was used. Sleep duration on weekdays and subjective sleep satisfaction during the past week were asked. Participants' perceived health, happiness, stress, depressive mood, and suicidality during past 12 months were also investigated. Participants were classified by mean duration of daily sleep time and the level of sleep satisfaction, and the odds of having mental health problems were compared. Results : Compared to adolescents who slept more than 6 hours per day and satisfied with their sleep, adolescents who slept less than 6 hours per day and/or dissatisfied with their sleep were less likely to perceive themselves healthy and happy. They were also more likely to have severe stress, depressive mood, and suicidality, with highest odds ratios among adolescents with both short and dissatisfying sleep. Conclusions : Given the significant associations between sleep insufficiency and mental health problems, attention to the sleep shortage among Korean adolescents is needed. Prospective studies are warranted to elucidate the causal relationships between subjective and objective sleep insufficiency and psychiatric conditions.

Effects of physical attributes of workstation enclosures on the performance of office workers with different difficult levels of office tasks and moods are presented. Performance scores in complex tasks were expected to increase with greater workstation enclosures while those in simple tasks would be the same. Mood ratings were expected to be higher in lower workstation enclosures. Performance of 102 college students on ambient office sounds (45 dBA) with office tasks were measured for 100 minutes under three different workplace enclosures: (1) four foot partitions on two sides; (2) six foot partitions on three sides; and (3) a fully enclosed workstation with eight foot partitions. The tasks were to memorize a paragraph with 130 words (complex task) and to search phone numbers (simple task). The complex task performance in the fully enclosed workstation was increased compared to that in the workstation with four foot partitions (p < 0.001) and to that in the workstation with six foot partitions (p < 0.05). However, occupants in the fully enclosed workstation with office sounds without speech generally gave higher mood ratings. It indicates that closed individual offices may offer important contributions to collaborative work as well as individual productivity. These findings would help design community revise open plan design to increase collaboration among office workers.
