Objective : Eye movement desensitization and reprocessing (EMDR) has been established as an effective treatment for patients with posttraumatic stress disorder (PTSD). However, the literature is unclear as to whether EMDR is effective in the treatment of other psychiatric disorders. The purpose of this study was to evaluate the potential use of EMDR in the treatment of psychiatric disorders other than PTSD by using a clinician's impression of patient response and a subjective symptom evaluation. Methods : Seventeen diagnostically heterogenous patients without PTSD underwent an average of 4.3 sessions of EMDR. Symptom severity was assessed by the Clinical Global Impression-Change Scale (CGIC), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and Symptom Checklist-90- Revised (SCL-90-R) before and after EMDR. Those whose CGI-C scores were 'very much improved' and 'much improved' after EMDR were classified as 'responders.' The patients' before and after treatment scores of symptom severity and group differences were compared. Results : Twelve of the 17 participants (12/17, 71%) were classified as 'responders.' The patients' scores on all of the scales, with the exception of the trait anxiety scale and obsession-compulsion scale of the SCL- 90-R, significantly decreased after treatment. There was no difference in sociodemographic and clinical variables between the responders and non-responders. Conclusion : The results of our study suggest that EMDR can be a promising candidate for the treatment of patients with psychiatric disorders other than PTSD, and thus further controlled studies are needed to determine whether EMDR can be applied to various psychiatric populations.

Objectives: This study was designed to assess the change of heart rate variability (HRV) at resting, upright, and psychological stress states in depressive disorder patients. Methods: HRV was measured at resting, upright, and psychological stress states in 62 depressive disorder patients. We used visual analogue scale (VAS) score to assess tension and stress severity. Beck depression inventory (BDI) and state trait anxiety inventories I and II (STAI-I and II) were used to assess depression and anxiety severity, respectively. Differences between HRV indices and VAS score were evaluated using paired t-tests. Gender difference analysis was conducted with ANCOVA. Results: SDNN (standard deviation of normal to normal intervals), LF/HF (low frequency/high frequency), and VLF (very low frequency) were significantly increased, while NN50 and pNN50 were significantly decreased in the upright position compared to resting state. SDNN, RMSSD (root mean square of the differences of successive normal to normal intervals), and VLF were significantly increased, while pNN50 was significantly decreased in the psychological stress state compared to resting state. SDNN, NN50, and pNN50 were significantly lower in an upright position compared to a state of psychological stress, and LF, HF, and LF/HF showed no significant differences Conclusion: The LF/HF ratio was significantly increased after physical stress in depressive disorder. However, the LF/HF ratio was not significantly increased after psychological stress, and the change in LF/HF ratio after physical stress and psychological stress did not significantly differ from each other. Significant increase in SDNN, NN50, and pNN50 in an upright posture compared to psychological stress suggests that depressive patients react more sensitively to physical stress than psychological stress.

Purpose: This study was to explore elderly people's elder abuse experiences, and the relations between the abuse experiences (direct and indirect) and their level of activities of daily living, family relations and self-integrity. Method: A descriptive survey was conducted, and the participants were 108 elderly people. Data were analyzed using SPSS by descriptive statistics and t-test. Result: It was that indirect abuse experiences of the elder was higher than direct abuse experiences. In this research, the most common kind of direct elder abuse was 'psychological abuse and negligence', and the severity was low. The largest portion of indirect abuse experiences belonged to 'physical abuse and negligence', and the severity was high. The older people who had direct abuse experiences showed lowered self-integrity and serious family problems and stress. Conclusion: The experiences of elder abuse showed differences in family relations and self integrity. Hence, there should be a nursing intervention improving psycho-social factors such as self integrity and family relations, and systematic and easily available supporting organizations for victims of elder abuse.

The major purpose of this research was to investigate the causal relationships among working wives' work-family conflict, socialization of housework, and home management satisfaction. the double ABCX model of family stress and adaptation provided the theoretical framework for this study. the data were recruited from working wives who had more than one pre-school child. The respondents were asked to complete the self-administered questionnaires, and the responses of 536 working wives were used for the final analysis. basically Cronbach's α to the reliability of major variables, frequencies, percentages, means, standard deviation, pearson's correlation coefficients, and LISREL 7 program were performed to test the research model. The results of this study can be summarized as follows : 1. The frequency of work-family conflict was affected by the flexibility of work time and wives' income. 2. The severity of wok-family conflict was directly influenced by the frequency of the conflict, the flexibility of work-time, and wives' education level. 3. The variables influencing the degree of socialization of housework were found to be the frequency and the severity of work-family conflict, wives' education, and the degree of husband's participation in housework. 4. The higher degree of home management satisfaction was associated with the higher level of family member's health status, the greater degree of the flexibility of work-time, and the greater degree of husband's participation in household labor.

This study aimed to analyze the fatigue of forklifts in industrial settings by assessing their stress levels during operation. Strain gauges were affixed to the dynamic components of the forklifts to gather real-time data and enhance the reliability of the analysis. Although monitoring structural loads in harsh testing environments can be challenging, the affixed strain gauges on the dynamic components can provide more precise results and improve the interpretation of data. By creating testing modes that simulate forklift usage environments and performing experiments with selected cargo and driving modes, a comparison of the damage severity of forklift parts under different driving conditions was done. These results can be utilized to forecast the lifespan of forklift parts under extreme driving conditions and assist in the design and optimization of new parts in the future.

Advances in medical procedures and utilization of medication have resulted in expanding aged population, which leads to increased aged patients with salivary hypofunction and its associated symptoms in dental clinic. The purpose of this study was to investigate clinical characteristics of patients with dry mouth and its correlation with their salivary flow rate. Forty dry mouth patients (7 males, 33 females, mean age 42.0 years) whose flow rate of unstimulated whole saliva was less than 0.15 ml/min were included and their gender- and age-matched controls (7 males, 33 females, mean age 42.9 years) who did not report any complaints, suggestive of salivary gland dysfunction and had the flow rate of greater than 0.20 ml/min were included for comparison. The salivary flow rate was measured in both unstimulated and stimulated conditions. Dry mouth-related clinical information including history, dry mouth associated symptoms, exacerbating and relieving factors, drugs, systemic diseases, and family history was investigated using questionnaires. The differences in distribution of patients and control subjects to each question and their relation to the salivary flow rate were analyzed and we came to following conclusions. 1. There were statistically significant differences in the distribution of patients and controls to the following questions: the period and frequency of suffering from dry mouth; severity of dry feeling during a meal; severity of discomfort during swallowing; necessity of sipping liquids during swallowing dry foods, severity of discomfort in usual life due to dry feeling; self-assessment of residual salivary volume; taking medications. 2. The patients had more stress-related medical histories including indigestion, insomnia, and gastritis compared with controls. The patients took many kinds of medications to control their systemic diseases. 3. There were statistically significant differences in the salivary flow rate between different groups of patients to following questions: severity of dry feeling during a meal; severity of discomfort during swallowing; necessity of sipping liquids during swallowing dry foods. The difference was more significant in the case of stimulated salivary flow rate rather than unstimulated one. 4. The salivary flow rate of patients taking medications was significantly less than that of patients who did not take medications. The difference was more significant in the case of stimulated salivary flow rate rather than unstimulated one.

Purpose: This study was done to develop and test a structural model for caregiving experience including caregiving satisfaction and caregiving strain in families providing care for family members with a mental disorder. Methods: The Stress-appraisal-coping model was used as the conceptual framework and the structural equation model to confirm the path that explains what and how variables affect caregiving experience in these families. In this hypothesis model, exogenous variables were optimism, severity of illness and uncertainty. The endogenous variables were self efficacy, social support, caregiving satisfaction and caregiving strain. Data were collected using structured questionnaires. Results: Optimism and caregiving self-efficacy had significant direct and indirect effects on caregiving satisfaction. Optimism, severity of illness and uncertainty had significant direct and indirect effects on caregiving strain. The modified path model explained effects of optimism on caregiving self-efficacy with social support in the path structure as a mediator. Also, there were direct and indirect effects of optimism and uncertainty on caregiving satisfaction with social support and caregiving self-efficacy in the path structure as a mediators. Conclusion: Results suggest the need to improve caregiving self-efficacy of these families, establish support systems such as a mental health professional support programs for caregiving self-efficacy. Optimism, severity of illness and uncertainty perceived by families need to be considered in the development of support programs in order to increase their effectiveness.

Purpose: This study was conducted to identify risk factors that influence the probability and severity of elder abuse in community-dwelling older adults. Methods: This study was a cross-sectional descriptive study. Self-report questionnaires were used to collect data from community-dwelling Koreans, 65 and older (N=416). Logistic regression, negative binomial regression and zero-inflated negative binomial regression model for abuse count data were utilized to determine risk factors for elder abuse. Results: The rate of older adults who experienced any one category of abuse was 32.5%. By zero-inflated negative binomial regression analysis, the experience of verbal-psychological abuse was associated with marital status and family support, while the experience of physical abuse was associated with self-esteem, perceived economic stress and family support. Family support was found to be a salient risk factor of probability of abuse in both verbal-psychological and physical abuse. Self-esteem was found to be a salient risk factor of probability and severity of abuse in physical abuse alone. Conclusion: The findings suggest that tailored prevention and intervention considering both types of elder abuse and target populations might be beneficial for preventative efficiency of elder abuse.

The aim of this study is to evaluate the clinical outcome. Between January 1,2002 to September 30, 2002, we prospectively and retrospectively recruited III hospitalized patients who received Enteral Nutrition (EN group n = 52) and Total Parenteral Nutrition (TPNgroup n = 59) for more than seven days. The factors of clinical outcomes are costs, incidences of infection, lengths of hospital stay, and changes in weight. The characteristics of patients were investigated, which included nutritional status, disease severity CAP ACHE III score) and hypermetabolic severity Chypermetabolic score). Hypermeta-bolic scores were determined by high fever (> $38^{\circ}C$), rapid breathing (> 30 breaths/min) , rapid pulse rate (> 100 beats/min), leukocytosis (WBC > 12000 $mm^{3}$), leukocytopenia (WBC > 3000 $mm^{3}$), status of infection, inflammatory bowel disease, surgery and trauma. There was a positive correlation between hypermetabolic score and length of hospital stay (ICU), medical cost, weight loss, antibiotics adjusted by age while APACHEIII score did not show correlation to clinical outcome. Medical cost was higher by $18.2\%$ in the TPN group than the EN group. In conclusion, there was a strong negative correlation between the clinical outcome (cost, incidence of infection, hospital stay) and hypermetabolic score. Higher metabolic stress caused more malnutrition and complications. For nutritional management of patients with malnutrition, multiple factors, including nutritional assessment, and evaluation of hypermetabolic severity are needed to provide nutritional support for critically ill patients.
