  • Ginseng effectively regulates the immune response and the hormonal changes due to stress, thus maintaining homeostasis. In addition to suppressing the occurrence of psychological diseases such as anxiety and depression, ginseng also prevents stress-associated physiological diseases. Recent findings have revealed that ginseng is involved in adjusting the hypothalamic-pituitary-adrenal axis and controlling hormones, thus producing beneficial effects on the heart and brain, and in cases of bone diseases, as well as alleviating erectile dysfunction. Recent studies have highlighted the potential use of ginseng in the prevention and treatment of chronic inflammatory diseases such as diabetes, rheumatoid arthritis, and allergic asthma. However, the mechanism underlying the effects of ginseng on these stress-related diseases has not been completely established. In this review, we focus on the disease pathways caused by stress in order to determine how ginseng acts to improve health. Central to our discussion is how this effective and stable therapeutic agent alleviates the anxiety and depression caused by stress and ameliorates inflammatory diseases.

  • Chronic fatigue syndrome Is a syndrome of unknown etiology and pathophysiology characterized by severe, chronic, debilitating fatigue as main symptom and numerous additional symptoms such as joint and muscle pain, headache, sleep disturbance. According to recent researches, it was suggested that chronic fatigue syndrome was developed by disturbance of interaction between neuropsychiatric system and immune system due to environmental factors and stress. Many patients experience gradual improvement but complete recovery from disorderd state is rare. There was no research elucidating the exact pathogenetic mechanism of chronic fatigue syndrome, so there was no established treatment. Several controlled studies about treatment was reported, but its results was not effective in all patients with chronic fatigue syndrome. For chronic fatigue syndrome, a comprehensive approach to physical, psychological, and social aspects is needed.

  • Hypnosis is an altered state of consciousness that comprises of heightened absorption in focal attention, dissociation of peripheral awareness, and enhanced responsiveness to social cues. Hypnosis has a long tradition of effectiveness in controlling somatic symptoms, such as pain. Pain, the most common symptom in clinical practice, is a multi-dimensional experience, which includes sensory-discriminative, affective-emotional, cognitive and behavioral components. There is a growing recognition for hypnosis and related techniques in pain management. Psychological approaches to pain control, such as hypnosis, can be highly effective analgesics, but are underused in Korea. In this article, we would like to review the basic concepts of hypnosis, the mechanism, and the outcome data of the analgesic effects of hypnosis, and also, its limitations.

  • Despite the increasing use of digital media and their powerful impact on risk management during recent outbreaks of emerging infectious diseases, the question of how digital media exposure influences preventive behaviors has not been fully explained. Using the appraisal tendency framework and protection motivation theory as theoretical frameworks, we theorized the affective and cognitive mechanisms under which the differential roles of three negative emotions (fear, anger, worry) on two cognitive appraisals (perceived threat and perceived efficacy) were examined. Based on data collected from a survey of 1,500 South Koreans during the COVID-19 pandemic, we found that while worry and anger increased perceived efficacy, fear reduced perceived efficacy. The results also showed that although exposure to COVID-19 information via digital formats increased preventive behavioral intention in general, digital media use for COVID-19 information had a negative influence on preventive behavioral intention through the sequential mediation of fear and perceived efficacy.

  • People differ greatly in their capacity to persist in the face of challenges. Despite significant research, relatively little is known about cognitive factors that might be involved in perseverance. Building upon human threat-management mechanism, we predicted that perseverant people would be characterized by reduced sensitivity (i.e., longer detection latency) to threat cues. Our data from 5,898 job applicants showed that highly perseverant individuals required more time to correctly identify anger in faces, regardless of stimulus type (dynamic or static computer-morphed faces). Such individual differences were not observed in response to other facial expressions (happiness, sadness), and the effect was independent of gender, dispositional anxiety, or conscientiousness. Discussions were centered on the potential role of threat sensitivity in effortful pursuit of goals.

  • Because of increasing anxiety about infectious diseases and the demand for contactless service caused by the COVID-19 pandemic, it has become crucial for the tourism and hospitality sector to understand customers' psychological mechanism of contactless service during and post COVID-19. Thus, this paper proposes a conceptual model by integrating trust in the framework of the behavioral immune system. Interestingly, our study found that anxiety about infectious diseases during the COVID-19 pandemic has not only increased hotel customers' desire for contactless service and changed their behavioral intentions, but it has also impacted customers' trust in hotel service robots. Therefore, irrespective of how the hotel service environment changes, trust in technology has become the most fundamental factor for hotel customers' attitudes toward adopting technology. Based on the results, this paper provides salient theoretical and practical implications.

  • Conversion Disorder is a disorder whose predominant feature is a loss or alteration in physical functioning that suggests a physical disorder but that is actually a direct expression of a psychological conflict or need. The Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) guidelines for Conversion Disorder include these definitions: A psychosocial stressor produces a psychological conflict that is believed to help initiate or exacerbate the illness The symptoms are not under conscious control, etc. While functional disabilities are common with conversion disorders, physical and laboratory abnormalities are absent or minor in comparison with the patient's subjective complaints. Symptoms of Conversion Disorder are similar to those of stroke. But the mechanism of Conversion Disorder is similar as that of Stagnation Syndrome of Ki (氣鬱證) in Oriental medicine. Gaegyeolseogyeong-tang has been used to treat women who suffer from Conversion Disorder induced by the Stagnation Syndrome of Ki (氣鬱證). After application of the Gaegyeolseogyeong-tang for 7 days, symptoms and signs improved dramatically.

  • Objective : We examined the putative association between the psychological symptoms and hypoxemia in hospitalized pneumoconiosis patients. Methods : One hundred and nine hospitalized pneumoconiosis patients were divided into two groups according to their level of hypoxemia (PaO2); hypoxemic group consisted of 47 patients with PaO2 lower than 80 mmHg, and comparative group consisted of 62 patients with higher than 80 mmHg. All of them were interviewed with the Hamilton Depression Rating Scale (HAM-D), and completed the Symptom Checklist-90items-Revised (SCL-90-R) and the State-Trait Anxiety Inventory (STAI). The medical data (PaO2, PaCO2, Hb, and Hct), number of hospital days and socio-demographic data as well as scores of the three psychological measurements were compared between the two groups. Results : Hypoxemic patients with lower PaO2 showed higher scores in the HAM-D (p=0.01) and stateanxiety subscale of the STAI (p<0.05). Values of hemoglobin and hematocrit were negatively correlated with levels of trait-anxiety (p<0.05). Thirty patients (27.5%) of total subjects suffered from depression (higher than 18 in the HAM-D), and 46.8% of hypoxemic patients were depressed, whereas 12.9% of comparative group patients were depressed (p=0.01). Conclusion : These results suggest that depression and anxiety might be associated with the hypoxemic mechanism in pneumoconiosis patients.

  • This study tested the roles of public self-consciousness, body surveillance, body shame, and body dissatisfaction based on culture cultivation theory and self-objectification theory with the aim of revealing the psychological mechanisms underlying the influence of media exposure on diet intention. As a result of conducting a survey on 350 women in their twenties and performing structural equation modeling, this study found that media exposure causes public self-consciousness, which increases body surveillance and body shame, thereby increasing body dissatisfaction and thus increasing diet intention. In addition, public self-consciousness indirectly influenced body shame through body surveillance. Body surveillance was found to have an indirect effect on diet intention through body dissatisfaction, whereas body shame had a direct effect on diet intention. Based on the results, we presented theoretical and practical implications of this study and suggestions for future research.

  • Background: With the increasing demand for industrial robots and the "noncontact" trend, it is an appropriate point in time to examine whether risk assessments conducted for robot operations are performed effectively to identify and eliminate the risks of injury or harm to operators. This study discusses why robot accidents resulting in harm to operators occur repetitively despite implementing control measures and proposes corrective actions for risk assessments. Methods: This study collected 369 operator-injured robot accidents in Korea over the last decade and reconstructed them into the mechanism of injury, work being undertaken, and bodily location of the injury. Then, through the techniques of Systematic Cause Analysis Technique (SCAT) and Root Cause Analysis (RCA), this study analyzed the root and direct causes of robot accidents that had occurred. Causes identified included physical hazards and complex combinations of hazards, such as psychological, organizational, and systematic errors. The requirements of risk assessments regarding robot operations were examined, and three case studies of robot-involved tasks were investigated. The three assessments presented were: camera module processing, electrical discharge machining, and a panel-flipping robot installation. Results: After conducting RCA and comparing the three assessments, it was found that two-thirds of injury-occurring from robot accidents, causative factors included psychological and personal traits of robot operators. However, there were no evaluations of the identifications of personal aspects in the three assessment cases. Conclusion: Therefore, it was concluded that personal factors of operators, which had been overlooked in risk assessments so far, need to be included in future risk assessments on robot operations.
