Purpose: This study was conducted to identify the differences by the stages of change in exercise behaviors of caregivers based on Transtheoretical Model. Methods: The subjects were consisted of randomly chosen 105 caregivers working in a nursing home. The collected data were analyzed with descriptive statistics, chi-square test, ANOVA and Duncan test using IBM SPSS Statistics 19. Results: The results showed that in the stages of exercise behaviors, there were most participants in contemplation stage with 24.7%, followed by 22.8% in preparation, 21.9% maintenance, 19.0% action and 11.4% pre-contemplation. As for the process of change by the stages of change in exercise behaviors, it showed statistically significant differences in behavioral strategies (F=7.64, p<.001). In decisional balance, pros (F=3.75, p=.007) showed statistical significance, with higher pros in all stages except pre-contemplation. Self-efficacy was also statistically significant (F=6.25, p<.001), especially in the maintenance stage. Conclusion: This study suggested that in order to encourage caregivers to exercise, a strategic intervention to reinforce the process of change, recognition of positive decision-making and promotion of self-efficacy in exercise behaviors should be developed.

The purpose of this study was to help young people with mild intellectual disabilities with counseling and self-supporting life experiences. The topic of the counseling contents could be categorized as follows: "institutional life was clumsy and hard, but it was also full of memories," "my adolescent was aching, growing, and lonesome," "an irresistibie being," "independence process is filled with anxiety, excitement." In his process of going independent, the subject showed a strong will for the preparation for independence where he gets through the unfavorable situation surrounding the arduous and lonely independent process. This result proves the effectiveness of the therapeutic intervention based on the coping skills that meet the needs of the social situation for the adolescents who are discharged from institutions in their independence preparation and job search.

Objectives : Recent educational efforts have concentrated on patient's early hospital arrival after symptom onset. The purpose of this study was to evaluate the time interval between symptom onset and hospital arrival and to investigate its relation with clinical outcomes for patients with acute ischemic stroke. Methods : A prospective registry of patients with signs or symptoms of acute ischemic stroke, admitted to the OO Medical Center through emergency room, was established from September 2003 to December 2004. The interval between symptom onset and hospital arrival was recorded for each eligible patient and analyzed together with clinical characteristics, medication type, severity of neurologic deficits, and functional outcomes. Results : Based on the data of 256 patients, the median interval between symptom onset and hospital arrival was 13 hours, and 22% of patients were admitted to the hospital within 3 hours after symptom onset. Patients of not-mild initial severity and functional status showed significant differences between arrival hours of 0-3 and later than 3 in terms of their functional outcomes on discharge. Logistic regression models also showed that arrival within 3 hours was a significant factor influencing functional outcome (OR=5.6; 95% CI=2.1, 15.0), in addition to patient's initial severity, old age, cardioembolism subtype, and referral to another hospital. Conclusions : The time interval between symptom onset and hospital arrival significantly influenced treatment outcome for patients with acute ischemic stroke, even after controlling for other significant clinical characteristics. The findings provided initiatives for early hospital arrival of patients and improvement of emergency medical system.

Objective : The purpose of this study was to identify independent predictors of mortality and functional recovery in patients with primary intracerebral hemorrhage (PICH) and to improve functional outcome in these patients. Methods : Data were collected retrospectively on 585 patients with supratentorial PICH admitted to the Stroke Unit at our hospital between 1st January 2004 and the 31st July 2008. Using multivariate logistic regression analysis, the associations between all selected variables and 30-day mortality and 90-day functional recoveries after PICH was evaluated. Results : Ninety-day functional recovery was achieved in 29.1% of the 585 patients and 30-day mortality in 15.9%. Age (OR=7.384, p=0.000), limb weakness (OR=6.927, p=0.000), and hematoma volume (OR=5.293, p=0.000) were found to be powerful predictors of 90-day functional recovery. Furthermore, initial consciousness (OR=3.013, p=0.014) hematoma location (lobar, OR=2.653, p=0.003), ventricular extension of blood (OR=2.077, p=0.013), leukocytosis (OR=2.048, p=0.008), alcohol intake (drinker, OR=1.927, p=0.023), and increased serum aminotransferase (OR=1.892, p=0.035) were found to be independent predictors of 90-day functional recovery after PICH. On the other hand, a pupillary abnormality (OR=4.532, p=0.000) and initial unconsciousness (OR=3.362, p=0.000) were found to be independent predictors of 30-day mortality after PICH. Conclusion : The predictors of mortality and functional recovery after PICH identified during this analysis may assist during clinical decision-making, when advising patients or family members about the prognosis of PICH and when planning intervention trials.

Purpose: The purpose of this study was to identify relationships of resilience, Post-Traumatic Stress Disorder(PTSD), and quality of life of breast cancer patients. The findings from this study would provide baseline data needed for nursing intervention. Methods: A sample of 129 breast cancer patients was recruited from three hospitals in J and C cities in Korea. The survey was conducted with participants by utilizing self-reported questionnaires. Results: Quality of life showed statistically significant differences on religion (t=2.11, p=.033) and hobby (t=2.79, p=.006). Resilience and PTSD had a negative correlation (r=-.22, p=.010). Resilience and quality of life of the participants had a positive correlation (r=.58, p<.001), whereas PTSD and quality of life had a negative correlation (r=-.45, p<.001). Significant predictors of quality of life were resilience and PTSD. These variables explained 44.9% of the variance in quality of life. Conclusion: Findings indicate that as resilience of breast cancer patients rose higher and PTSD got lower, their quality of life increased. Based on these results, nursing interventions directed towards improving resilience and relieving PTSD is proposed.

The purpose of this study was to develop and empirically evaluate a theoretical model that delineated the processes whereby parents' socioeconomic status affected students'academic achievement via parental support and students' ego-resilience. The proposed model was tested with the first and second wave of a cohort sample of the first grade middle school students from the Korean Children Youth Panel survey by using linear structural relations techniques. The results of analysis showed firstly that parents' socioeconomic status, parental support and students' ego-resilience directly affected the level of students'academic achievement with statistical significance. Secondly, parental support, the proxy of social capital of the family, was contingent upon the parents'socioeconomic status. Thirdly, in addition to its direct effect, parents'socioeconomic status gave indirect effect on students' academic performance through parental support and ego-resilience. Based upon these results implications for social work intervention were provided.

Wireless sensor networks collect and analyze sensing data in a variety of environments without human intervention. The sensor network changes its lifetime depending on routing protocols initially installed. In addition, it is difficult to modify the routing path during operating the network because sensors must consume a lot of energy resource. It is important to measure the network performance through simulation before building the sensor network into the real field. This paper proposes a WSN model for a low-energy adaptive clustering hierarchy protocol using DEVS kernel models. The proposed model is implemented with the sub models (i.e. broadcast model and controlled model) of the kernel model. Experimental results indicate that the broadcast model based WSN model showed lower CPU resource usage and higher message delivery than the broadcast model.
