  • This study was performed to investigate the negative side effects of video display terminal (VDT) work on the human body and to provide data for preventing VDT syndrome. A questionnaire survey was made to 339 VDT workers at 22 offices in Taegu, Kyungpook and Kyungnam areas from July 1 to August 31, 1994, and 280 of them were finally used for statistical analysis. The VDT syndrome in the present study inclhded five factors, namely as eye-related symptom, psychological symptom, general body symptom, musculoskeletal symptom, and skin-related symptom, and the estimates of Crombach coefficients of the five factors were 0.954, 0.952, 0.953, 0.957, and 0.955, respectively, showing very high reliability. In view of socio-economical characteristics, the symptoms of female were higher than those of male in the order of musculoskeletal symptom, eye-related symptom, skin-related symptom and psychological symptom. The age group of 30 years or less was higher than the older groups in the order of musculoskeletal symptom, eye-related symptom, psychological symptom and skinrelated symptom. The group of lower education level showed higher skin-related symptom. The psychological symptom and skin-related symptom increased as the amount of smoking increased. Higher eye-related symptom was observed in the group without glasses. In the job-related variables, the group of working on programming and data input showed higher eye-related symptom and psychological symptom. The group of working on programming and graphic design showed higher musculoskeletal symptom and skin-related symptom. The skin-related symptom increased as the total time of VDT operation per day increased. The group of working 2-4 hours followed by 15 minutes rest was higher in musculoskeletal symptom and psychological symptom. Higher musculoskeletal symptom was observed from the group working on Friday and Sunday. The group of 1 year or less working showed higher in skin-related symptom. In relation with the VDT type, all symptoms except skin-related symptom were higher in the group using monochrome monitor. As showed above, the questionnaire could be a tool for evaluating VDT syndrome and prevention of the syndrome would be possible by a comprehensive consideration of factors including socio-economic characteristics, job-related variables and VDT type.

  • Purpose: The purpose of this study was to identify symptom cluster experienced by patients with advanced non-small cell lung cancer (NSCLC) on gefitinib treatment. In addition, this study assessed the patterns in severity of the symptom cluster and differences in quality of life (QOL) and function among subgroups by the severity of symptom cluster. Methods: This study was conducted as a secondary analysis of symptoms of 72 patients from a mother study. Factor analysis was used to identify symptom clusters measured with EORTC QLQ-C30 and LC13 symptom related items. Results: Three symptom clusters were identified: cluster 1 was comprised of fatigue, anorexia and dysphagia; cluster 2 of dyspnea, cough and insomnia; and cluster 3 of pain, constipation and nausea/vomiting. These three symptom clusters were improved one week after gefitinib administration. The group with more severe symptom clusters showed significantly lower QOL and function than the group with less severe symptom clusters. Conclusion: Since symptom clusters experienced by the patients with advanced NSCLC influenced on the QOL and function, it is important for nurses to understand and observe their symptom clusters. In addition, there is an necessity to develop nursing interventions to effectively care patients with the symptom clusters.

  • The purpose of this study was to identify the relationship of symptom distress and natural killer cell cytotoxicity in breast cancer patients who had been radiation therapy and/or chemotherapy after surgery. Symptom distress measured by modified Lee's(1994) physical symptom questionnaire. For measuring the natural killer cell cytotoxic activity. 8ml to 10ml blood was collected from the subjects. Mononuclear cell was isolated by centrifuge of the blood and cultured by putting $Cr^{51}$, and reacted with target cell, K562 cell. Amount of $Cr^{51}$ was measured, and %lysis was calculated. The results were as follows. 1) Symptom distress score was 42.18, which is moderate symptom distress. 2) Natural killer cell cytotoxic activities were 42.18%lysis(effector : target cell ratio=100 : 1) and 28.05%lysis(effector : target cell ratio=50 : 1). 3) Correlation coefficients of symptom distress and natural killer cell cytotoxic activity were $-.134{\sim}-.461$. Though significant correlation was not found between total score of symptom distress and natural killer cell cytotoxic activity, 3('pain' 'feel hot on radiation site' and 'difficulty in breathing') of 19 symptom distress items and natural killer cell cytotoxic activity showed significant negative correlation(p<.05). These findings suggest that 1) breast cancer patients who had been radiation therapy and/or chemotherapy after surgery have moderate symptom distress and decreased natural killer cell cytotoxic activity. 2) The symptom distress was not related to natural killer cell cytotoxic activity.

  • Objectives : Prevalence of night eating habit associated with substance use and obesity is increasing rapidly in children and adolescents. Further, staying up late and eating snacks late at night were known as leading health risk behaviors for children, suggesting the potential adverse effect of night-eating habit on children. However, only few reports had been issued on the effect of night-eating habit on gastrointestinal symptom and SUI-TAI(水滯) symptom of children. Therefore, we aimed to investigate clinical characteristics of children by night-eating symptom status. Methods : Parents were asked to give a detailed answer to a systemized medical history questionnaire concerning night-eating habit, gastrointestinal symptom and SUI-TAI symptom of their children. Medical records of 28 children treated in the Department of Pediatrics, Hospital of Oriental Medicine, were the subject of this study. Clinical characteristics of two groups of children who with no night-eating habit and frequent night-eating group(eating at night more than 3 times per week) were analysed. In addition, the correlation analysis between clinical characteristics were performed. Results : Children with frequent night-eating habit(n=7, more than 3 days of night-eating a week) were observed to have more aggravated gastrointestinal symptom and SUI-TAI symptom compared with those without night-eating habit(n=13). In parallel, the association of gastrointestinal symptom and SUI-TAI symptom was demonstrated(n=28). Conclusions : It is notable that deranged gastrointestinal function and aggravated SUI-TAI symptom were observed among children generally regarded as healthy. Therefore, endeavors to correct night-eating habit as well as to treat aggravated gastrointestinal and SUI-TAI symptoms are needed for the promotion of health of children.

  • Bian-zheng(辨證) of Korean Medicine(KM) is based on four examinations(四診) of Korean medical doctor. The interrogation or questioning(問診) provides the most information of four examinations. The symptom obtained from the interrogation or questioning is the main basis of the Bian-zheng. KM is understood in the whole state of the body of a specified time without seeing the disease exist. So the observable symptom is disease itself. Symptom in KM is used as an important basis for the diagnosis. But if the interview when memories are not sure of the correct answer does not get much easier to find exactly the symptoms. So when recording original symptom(素證) and daily subjective symptom can be helpful for care. In this paper, we propose daily living symptom record system as a method that can be applied to the health care according to the importance of collecting the symptom in the KM. Daily living symptom record system can record the symptom in the individual to awaken daily. The system stores the symptom in structure and provides an open shared services. So it can be used as a symptom of other systems, such as PHR, EMR, CDSS. In addition, Doctor may be able to help in the treatment determined by reference to shared symptom.

  • Purpose: The purpose of this study was to identify cancer-related symptom clusters and to validate the conceptual meanings of the revealed symptom clusters in patients with hepatocellular carcinoma. Methods: This study was a cross-sectional survey and methodological study. Patients with hepatocellular carcinoma (N=194) were recruited from a medical center in Seoul. The 20-item Symptom Checklist was used to assess patients' symptom severity. Selected symptoms were factored using principal-axis factoring with varimax rotation. To validate the revealed symptom clusters, the statistical differences were analyzed by status of patients' performance status, Child-Pugh classification, and mood state among symptom clusters. Results: Fatigue was the most prevalent symptom (97.4%), followed by lack of energy and stomach discomfort. Patients' symptom severity ratings fit a four-factor solution that explained 61.04% of the variance. These four factors were named pain-appetite cluster, fatigue cluster, itching-constipation cluster, and gastrointestinal cluster. The revealed symptom clusters were significantly different for patient performance status (ECOG-PSR), Child-Pugh class, anxiety, and depression. Conclusion: Knowing these symptom clusters may help nurses to understand reasonable mechanisms for the aggregation of symptoms. Efficient symptom management of disease-related and treatment-related symptoms is critical in promoting physical and emotional status in patients with hepatocellular carcinoma.

  • Objective : The aim of this study is to investigate the features of clinical trial which used symptom differentiation on cancer patients Method : Electronic databases including Ovid-Medline, Ovid-EMBASE, and Cochrane library were searched. Search terms incorporating the concepts of cancer, herbal medicine, clinical trial were used. Articles described using symptom differentiation in methods were selected. Results : Twelve studies used symptom differentiation for prescribing herbal medicine to cancer patients. A total of 36 symptom differentiation were used. The kind of the herbal medicines was varied as much as the kind of symptom differentiation. Conclusion : Most of herbal medicines used for cancer patients focused on quality of life or adverse events rather than tumor size. Symptom differentiation and herbal medicine used in selected studies were too diverse to categorize. To use standardized symptom differentiation, symptom differentiation instrument should be developed and reliability test and validity test are needed.
