Background: Gig workers, also known as platform workers, are independent workers who are not employed by any particular company. The number of gig economy workers has rapidly increased worldwide in the past decade. There is a dearth of occupational health studies among gig economy workers. We aimed to investigate the association between exposure to violence and job stress in gig economy workers and depressive symptoms. Methods: A total of 955 individuals (521 gig workers and 434 general workers) participated in this study and variables were measured through self-report questionnaires. Depressive symptoms were evaluated by the Patient Health Questionnaire-9 when the score was greater than or equal to 10 points. The odds ratio with 95% confidence interval was calculated using multivariable logistic regression adjusted for age, sex, working hours, education level, exposure to violence and job stress. Results: 19% of gig economy workers reported depressive symptoms, while only 11% of general workers reported the depressive symptoms. In association to depressive symptoms among gig economy workers, the mainly result of odds ratios for depressive symptoms were as follows: 1.81 for workers type, 3.53 for humiliating treatment, 2.65 for sexual harassment, 3.55 for less than three meals per day, 3.69 for feeling too tired to do housework after leaving work. Conclusions: Gig economic workers are exposed to violence and job stress in the workplace more than general workers, and the proportion of workers reporting depressive symptoms is also high. These factors are associated to depressive symptoms. Furthermore, the gig workers associated between depressive symptoms and exposure to violence, job stress.

Purpose: This study was conducted to examine the relationship between job stress and work-related musculoskeletal symptoms of hospital nurses. Method: The questionnaires were administered to 290 nurses working in a general hospital located in S city from September 1 to 15, 2008. The data were analysed with descriptive statistics, and logistic regression test by SPSS WIN 14.0. Results: With the NIOSH criteria 1, the musculoskeletal symptoms were prevalent in 66.8% of the subjects. The musculoskeletal symptoms by body parts appeared mostly on leg/foot(40.6%) and followed by shoulder (38.7%), waist(30.3%), neck(23.6%), hand/wrist/finger(14.0%) and arm/elbow(4.4%). There were statistically significant differences in prevalence rate of musculoskeletal symptoms by age, work department, career and job stress. Conclusion: When developing a management program for musculoskeletal symptoms of hospital nurses, it is necessary to fully understand nurses' work considering each hospital's nursing administration system.

Objectives : The aim of this study was to investigate relationships between psychotic symptoms and cognitive functions in schizophrenia. Methods : The study group was composed of 36 schizophrenic patients. Positive, negative, and disorganization symptoms were assessed using the PANSS. Verbal, visuospatial, attention, memory, and executive functions were assessed using a battery of cognitive tests. Results : Correlation analysis between symptom vs. cognitive measures showed that (a) positive symptoms were significantly correlated with no cognitive measures, (b) negative symptoms were significantly correlated with all cognitive measures, and (c) disorganization symptoms were significantly correlated with executive and memory measures. Correlation analyses between symptom vs. cognitive factors showed that negative-disorganization factor is significantly correlated with executive-memory factor. Conclusion : Significant relationships were confined mostly to frontal symptoms vs. frontal cognitive functions. Thus, the relationships may be mediated mainly by variations in severity of frontal pathology among patients.

Purpose: The purpose of this study was to examine the mediating effect of self-perception on the relationship between body image and depressive symptoms in middle school adolescents. Methods: This study performed a pathway analysis with a sample of 284 adolescents recruited from three middle schools. Self-reported questionnaires consisted of items regarding body image, self-perception, and depressive symptoms. Results: Body image, self-perception, and depressive symptoms showed a significant correlation. Self-perception was directly affected by body image and depressive symptoms were not affected by body image. The mediating effect of self-perception on body image's impact on depressive symptoms was confirmed. Self-perception had a significant indirect effect on depressive symptoms, which means that self-perception has a full mediating effect on body image's impact on depressive symptoms. Conclusion: The effect of body image on depressive symptoms was fully mediated by self-perception in early adolescents. It suggests that self-perception needs to be considered when providing nursing interventions for adolescents.

Purpose: This study investigated the cumulative effects of depressive symptoms on cognitive function over time in community-dwelling older adults. Methods: Data were investigated from 2,533 community-dwelling older adults who participated in the Korean Longitudinal Study of Aging (KLoSA) from the 5th (2014) to the 8th wave (2020). The association between cumulative depressive symptoms and cognitive function was identified through multiple regression analysis. Results: When the multiple regression analysis was conducted from each wave, the current depressive symptoms scores and cognitive function scores were negatively associated, regardless of the waves (B5th = - 0.26, B6th = - 0.26, B7th = - 0.26, and B8th = - 0.27; all p < .001). Further, when all the previous depressive symptoms scores were added as explanatory variables in the 8th wave, the current one (B8th = - 0.09, p < .001) and the previous ones (B5th = - 0.11, B6th = - 0.09, and B7th = - 0.13; all p < .001) were also negatively associated with the cognitive function score. The delta R², which indicates the difference between the model's R² with and without the depressive symptoms scores, was greater in the model with all the previous and current depressive symptoms scores (6.4%) than in the model with only the current depressive symptoms score (3.6%). Conclusion: Depressive symptoms in older adults have a long-term impact. This results in an accumulated adverse effect on the cognitive function. Therefore, to prevent cognitive decline in older adults, we suggest detecting their depressive symptoms early and providing continuous intervention to reduce exposure to long-term depressive symptoms.

Conversion disorder is defined as a specific and enduring sensorimotor dysfunction that contradicts known neurological or musculoskeletal pathology or physical findings. The patient with conversion symptoms unconsciously adopts these symptoms to convert their psychological stress to a physical phenomenon. Conversion disorder often involves the mimicry of organic symptoms similar to those experienced by a relative or an acquaintance. Because conversion symptoms are produced by psychological stress, specific treatment strategy and reinforcement program are needed for treatment. Treatment comprises avoiding unnecessary medical tests and removing symptoms by using graded exercises given by physical therapists. Clinical therapists must maintain a continuous and detailed follow-up to completely recover from conversion symptoms. The goal of treatment is to emphasize health rather than disease, to resolve physical symptoms, and to prevent recurrence. This study looks into the case reports of 4 patients diagnosed with conversion disorder.

There appears to be an increased incidence of anxiety symptoms in association with certain medical illness. It is usually assumed that certain medical disorders are directly associated with anxiety symptoms in that the pathophysilolgy of the medical illness somehow causes the anxiety symptoms. However, the pathophysilolgies of many such medical illnesses as well as anxiety are not known and no discrete group of medical illnesses is clearly more likely to produce anxiety symptoms than any other Moreover, anxiety symptoms may be the representation of other psychiatric symptoms, like depression and delirium. Though it is important to differentiate primary and other causes(secondary) of anxiety clinically, the clear differentiation is somewhat arbitrary, as the confusion of mind-body dichotomy. for the purpose of accurate treatment of anxiety symptoms relating medical illness, this review article focuses on those clinical features and mechanisms of anxiety that are potentially useful in differential diagnosis.

Objectives The purpose of study was to identify cancer related symptoms of Sasang Constitution based on the classic of Sasang Constitutional Medicine (SCM). Methods The bibliographical study was performed with "Dongyisoosebowon-Shinchukbon(東醫壽世保元 辛丑本)", Dongyisoosebowon-Sasangchobongwon(東醫壽世保元 四象草本券), "Cancer", and several review articles. The perspective on severe illness in SCM was investigated. And 'the critical state' of constitutional symptoms based on "Dongyisoosebowon" was identified as cancer related symptoms. Results and Conclusions The perspective on severe illness of SCM was focused on the human being itself, compared with symptom based traditional Chinese medicine. The preservation of requisite energy (保命之主) was a vital factor of longevity to maintain healthy status and the classification of severity of disease. And critical state was an important indicator to control severe illness. Regarding cancer related symptoms in SCM, Janggwol(臟厥), Eumsung-gyeokyang(陰盛隔陽證), Janggyeol(藏結證) of Soeumin symptoms, Hwangdal(黃疸), Haso(下消), Eumheo-oyel(陰虛午熱證), Gochang, Tohyul(吐血) of Soyangin's symptoms, Joyeol(燥熱證), Bokchang-bujong(腹脹浮腫) of Taeeumin's symptoms, and Eolgyek of Taeyangin's symptoms could be shown the association with cancer. According to the prognosis on disease severity, regimens of daily life, behavior modifications as well as medications were also emphasized with great importance to control severe illness in SCM. These holistic approach for controlling severe illness in SCM could lead to the improvement of treatment outcome.
