The purpose of this study was to determine the influential factors associated with video display terminal (VDT) syndrome of male adolescents with digital device addition. The study design was cross-sectional descriptive survey. The study participants were 169 male middle school students in Seoul. A structured questionnaire was used for data collection and data were analyzed using the SPSS program. The factors most influential for the subjective symptoms of VDT were smartphone addiction, computer use time during the week, computer use environment. These factors accounted for 28.1% of the variance in subjective symptoms of VDT. In order to prevent the occurrence of VDT syndrome in students, we suggest to establish a preventive intervention against the digital addiction.

This study has been conducted to determine the fatigue symptoms(MFS) and its convergence association with occupational stress(KOSS) among small scale manufacturing male workers. The self-administered questionnaires were given to 428 workers employed in 14 work places under 50 members of manufacturing industries during the period from September 1st to 15th, 2015. As a results, the level of fatigue symptoms(MFS) was positively correlated with occupational stress(KOSS). Hierarchial multiple regression analysis revealed that the factors of influence with explanatory powers of 34.1% on fatigue symptoms(MFS) included sex, BMI, subject health status, smoking, regular exercise, drinking coffee, visiting out-patient department, sense of satisfaction in job life, and occupational stress(KOSS). Above results suggested that the level of occupational stress(KOSS) is so convergence influenced by variable factors as well as sociodemographic characteristics, health related characteristics and job-related characteristics, to a greater extent, by occupational stress(KOSS).

The purpose of this study attempted to collect basic data for development of an integrated self-management program for cancer survivors who completed cancer treatment. Self-management programs are divided into symptom management and physical activity management. Symptom management includes fatigue, sleep disturbance, pain, depression and anxiety. PubMed, CINAHL and EMBASE were used for searching guidelines. Based on the guideline quality evaluation, the final 8 guidelines were analyzed. The structured table was used to extract the screening subjects, timing, contents, subjects for comprehensive assessment and contents, and summarized contents related to the physical activity and exercise in non-pharmacological approach. As a result, after the completion of cancer treatment, all cancer survivors should be screened regularly using reliable and validated tools. In the case of fatigue, physical activity was recommended as the primary intervention, but it was recommended for other symptoms as adjuvant therapy. Therefore, Cancer survivors should be encouraged to be active in their physical activity, and maintain the moderate intensity physical activity as long as they have no complication related to the cancer treatment. Motivation strategies for physical activity need to be developed and applied.

The aim of this study was to provide fundamental data for the factors influencing the asthenopia of emmetropia with phoria and alleviation of asthenopia. A total of 348 subjects, aged between 19 and 30 years old, who had no strabismus, an eye trouble or whole body disease, were examined using corrected visual acuity, corrected diopter, stereopsis and suppression tests from September of 2002 to September of 2004. We excluded 21 subjects for the following reasons: if they had an amblyopia affecting binocular vision or inaccurate data. After these exclusions, 327 subjects remained. We then individually measured the refractive error correction, pupillary distance, optical center distance, phoria, convergence, accommodation and the AC/A as well as the asthenopia during binocular vision using a questionnaire. After analysis of factors affecting asthenopia, we also examined the reductive effect of a prism on the asthenopia in subjects who had asthenopia. To determine the factors affecting asthenopia during binocular vision, statistic analyses were carried out using the Chi-square test and the multivariate Logistic regression model. The results of this study were as follow. For asthenopia during near binocular vision of emmetropia with phoria, in case of the lower the accommodation and convergence, a significantly higher rate of asthenopia was observed (p<0.001). When the AC/A is lower, the higher the rate of asthenopia was observed but not significantly and there was no association between phoria and asthenopia. When the multivariate logistic regression model was used to determine factors affecting binocular vision of emmetropia with phoria, in case of the lower accommodation and convergence, a significantly higher rate of asthenopia was observed. when the phoria is esophoria or higher exophoria, or when the AC/A is lower than normal, the higher the rate of asthenopia was observed but not significantly and there was no association between phoria. AC/A and asthenopia. Therefore accommodation and convergence could be predictive factors for asthenopia during near distance binocular vision. Prism was used among' subjects who had asthenopia during near distance binocular vision, the symptom of asthenopia was eased up to 74.2% in emmetropia with phoria.

Most terminally ill cancer patients experience various physical and psychological symptoms during their illness. In addition to pain, they commonly suffer from fatigue, anorexia-cachexia syndrome, nausea, vomiting and dyspnea. In this paper, I reviewed some of the common non-pain symptoms in terminally ill cancer patients, based on the National Comprehensive Cancer Network (NCCN) guidelines to better understand and treat cancer patients. Cancer-related fatigue (CRF) is a common symptom in terminally ill cancer patients. There are reversible causes of fatigue, which include anemia, sleep disturbance, malnutrition, pain, depression and anxiety, medical comorbidities, hyperthyroidism and hypogonadism. Energy conservation and education are recommended as central management for CRF. Corticosteroid and psychostimulants can be used as well. The anorexia and cachexia syndrome has reversible causes and should be managed. It includes stomatitis, constipation and uncontrolled severe symptoms such as pain or dyspnea, delirium, nausea/vomiting, depression and gastroparesis. To manage the syndrome, it is important to provide emotional support and inform the patient and family of the natural history of the disease. Megesteol acetate, dronabinol and corticosteroid can be helpful. Nausea and vomiting will occur by potentially reversible causes including drug consumption, uremia, infection, anxiety, constipation, gastric irritation and proximal gastrointestinal obstruction. Metoclopramide, haloperidol, olanzapine and ondansetron can be used to manage nausea and vomiting. Dyspnea is common even in terminally ill cancer patients without lung disease. Opioids are effective for symptomatic management of dyspnea. To improve the quality of life for terminally ill cancer patients, we should try to ameliorate these symptoms by paying more attention to patients and understanding of management principles.

Purpose: The purpose of this longitudinal prospective study was to assess changes in fatigue and quality of life for a 6-week course of radiotherapy. Method: A descriptive and longitudinal design was used to this study. Twenty-three subjects receiving radiotherapy from a radiotherapy clinic of a general hospital completed the questionnaires. Fatigue was measured using Lee's scale(1999) and quality of life using Yang's scale(2002) weekly for 6 weeks. Result: Fatigue significantly increased(F=6.043, p=.000), and quality of life significantly decreased (F=3.938, p=.003) and physical symptoms also significantly increased(F=2.432, p=.039) during a 6-week radiotherapy. Multiple regression analysis revealed that fatigue at the first week and physical symptoms at the 6th week were the significant affecting variables(60.1% of the variance) on fatigue. And 63.2% of the variance in quality of life was explained by quality of life and fatigue at the first week and body weight change for 6 weeks radiotherapy. Conclusion: Based on these results, the fatigue and quality of life at the beginning time of radiotherapy have a lasting impact throughout the course of treatment. It suggests that nurses provide patients with information about the occurrence of fatigue during radiotherapy and the practical methods of intervening physical symptoms.

Purpose: The purpose of this study was to identify the effects of emotional labor, compassion fatigue and occupational stress on the somatization of nurses in hemodialysis units. Methods: The sample consisted of 139 nurses in hemodialysis units from a tertiary hospital, a general hospital, a dialysis clinic, and a care hospital in G province. Data were analyzed using frequencies, percentages, means and standard deviations, t-test, ANOVA, Duncan test, Pearson's correlation and hierarchical multiple regression. Results: There were significant correlations of the experience of emotional labor, compassion fatigue and occupational stress with the somatization of nurses in hemodialysis units. Factors influencing somatization intention were 'emotional labor' (${\beta}=.37$, p<.001), which explained 28% of the variance (F=10.00, p<.001). Conclusion: The results of this study indicate that the factor influencing the somatization of nurses in hemodialysis units was emotional labor. Therefore, strategies to decrease emotional labor of nurses in hemodialysis units are required.
