Objective: This study describes the change of operator performance in drastic change of illumination level, and proposes an alternative method to cope with it. Background: The control standard of illumination for nuclear power plants(NPPs) is based on the set of limit criteria for maintaining a specific illumination level. However, there is a possibility to cause human errors according to the psychological and physiological influences to operators in the situation of drastic change of illumination such as SBO(Station Black Out), so a basic study is necessary to review the current approach. Method: We assessed the visual fatigue, subjective work load and task performance according to the three illumination situations(Normal Illumination, Emergency Illumination, and Drastic Change of Illumination). Result: Research finding shows that there are not significant differences in task performance between normal illumination (1,000lx level) and emergency illumination (100lx level), only if beyond the dark adaptation limit. However, subjective work load on mental demand and visual fatigue show a potential challenge to visual performance in drastic change of illumination. Conclusion/Application: Several trials can complement this challenge in NPPs by applying 3-way communication, enhancing readability of procedures, and managing the visual factors affecting the operators' performance through a Visual Environment Management Program including visual health aspects, etc.

The purpose of this study was to show the occurrences of musculoskeletal disease in aging society and basic information on developments of a systematic prevention program and proposed management measures needed to prevent the disease. The Korea Occupational Safety & Health Agency has analyzed cases of industrial accidents that cause musculoskeletal disease, from 1998 to 2007. They found 30,439 people suffering from the disease during those ten years. This information is from the Ministry of Labor's industrial accident analysis and the industrial accident survey from the Korea Occupational Safety & Health Agency. The data was analyzed by age and industrial classification. In Korea, according to the studies on aging society, the occurrence of musculoskeletal disease in elderly employee's have increased, so prevention programs are needed. Psychological, mental and cognitive programs are needed, as well as other prevention programs to ensure health in old age. In this study, we were able to see the state of musculoskeletal disease in aging society and the countermeasures to prevent the disease, such as a universal design, guarantees, and recuperation services. Later, we found that studying the various elderly patients would be of great help to us.

Majority of the seniors living in nursing homes suffer from persistent chronic pain, which may cause depression and compromised quality of life if untreated. The environment should support them to lift their focus from current pain and worries to the positive feelings and the delight of life. The purpose of this research is to classify the healing environment elements for positive distraction, and analyze 6 international cases to see the current situation. The elements were categorized as follows, based on literature review from both healing spaces and elderly care field: spatial elements(view, natural elements, artificial elements, exercise space, garden), psychological elements(grooming area, space for privacy, meal/drink area, elements for recollection, religious space), social elements(common living area, activity/hoppy room, family/visitor area, information area, local community program space). Analysis on 6 facilities showed that each elements were reflected to designed relatively well. New inventions from workers who think distraction is important were also introduced. Healing environment for positive distraction requires delicate touch, derived from understanding characteristics and situation of the residing elderly individuals. Technology update is also significant, from audio books to virtual reality devices, since cultural life of nursing home is far behind from what the others enjoy now.

Background: Hepatocellular carcinoma (HCC) is the most common primary liver cancer and the third leading cause of cancer-related death worldwide due to its generally poor prognosis. Caregiver burden for liver cancer cases is higher than with other cancer and needs especial attention. Methods: To explore the experiences of families of patients with newly diagnosed advanced terminal stage hepatocellular cancer by interview. Results: Nine participants were recruited in this study. Content analysis of the interviews revealed four themes: blaming oneself, disrupting the pace of life, searching all possible regimens, and not letting go. Conclusions: This study provides new insight into the needs and support of family members especially when they are facing loved ones with newly diagnosed advanced terminal stage HCC. These results will inform future supportive care service development and intervention research aimed at providing assistance in reducing unmet supportive care needs and psychological distress of these family members.

We are exposed to the various external stimuli input from the environment, which cause emotional changes based on the characteristics of the stimuli. Unfortunately, there are no quantitative results on relationship between human sensibility and the characteristics of physiological signals. The objective of this study was to quantify EEG signals evoked by visual stimulation based on the assumption that the analysis of the variability on the characteristics of the EEG waveform may provide the significant information regarding changes in psychological states of the subject. Seven university students were participated in this study. The experiment was devised with eleven experimental conditions, which are control and ten different types of visual stimulation based on IAPS (International Affective Picture Systems). Wavelet transformation was employed to analyze the EEG signals. Most positive and negative emotional response were compared in pairs. The results showed that the reconstructed signals at the decomposition level revealed the different energy value on the EEG signals. Also, general patterns of EEG signals in rest state compare with positive and negative stimulus were found. This study could be extended to establish an algorithm which distinguishes psychophysiological states of the subjects exposed to the visual stimulation.

The number of disasters caused by natural or human-made events such as earthquakes, tsunamis, floods, typhoons, industrial disasters, and the recent outbreak of COVID-19 has increased and the damage caused by such disasters is increasing every year. Disasters can cause physical destruction and also have unexpected psychological impacts, such as post-traumatic stress disorder (PTSD). Ear acupuncture is a treatment modality that can be helpful for both physical and mental health problems. Since ear acupuncture is a cost-effective, flexible, and safe treatment tool, it has the potential to provide medical assistance in disasters. The National Acupuncture Detoxification Association (NADA) auricular acupuncture protocol, originally developed for addiction treatment, has been used for mental illness and behavioral symptoms in both community health settings and in a variety of disaster, terror, and refugee settings. In this review, we introduced the NADA protocol, including its history, features, training, clinical evidence, and cases in disaster settings, suggesting that the NADA protocol could be utilized as a disaster medical support model in Korean medicine.
