Purpose: The purpose of this study was to investigate the effects of a rehabilitation nursing program(RNP) for persons with disabilities. Method: a quasi-experimental pretest and post test study was used to examine the changes of patient's muscle strength, flexibility, self efficacy and health related quality of life at the completion of an 8-week education and physical exercise with a Thera-Band and Exercise Ball course. The subjects consisted of 40 adults who were disabled. Twenty-two experimental and 18 control subjects completed pre and post-test measures. Outcome variables were flexibility, hand grip, elbow flexor and extensor, knee flexor and extensor, self efficacy and quality of life. Independent t-test and ANCOVA were used to examine group differences by using SPSS 12.0 Result: Mean comparisons of the change scores revealed that the experimental group increased significantly in knee extremity flexor(p=0.035), extensor(p=0.039), flexibility(p=0.008), self efficacy(p=0.000), and quality of life(p=0.000). No significant group differences were found in each patient's hand grip, elbow flexor and extensor. Conclusion: RNP can improve lower extremity flexibility, muscle strength, self efficacy and health related quality of life in people with disabilities.

This study examined the hygiene practices of contract foodservice employees and investigated the influence of education and work environment on these hygienes practices. A questionnaire was distributed to 250 contract foodservice employees and a total of 232 responses were received and analyzed. The overall score for hygiene practices of contract foodservice employees was 3.89 based on a 5-point scale. Cross-contamination was prominent (highest score at 4.46) and the heating temperature was less prominent (lowest score at 3.49). The factors most affecting contract foodservice employees were their work period, the size of the contract foodservice management company, the number of meals served daily, the frequency of meal service per day and the frequency of hygiene education. Compared to small and medium-sized contract foodservice management companies, the major contract foodservice management companies showed higher scores for refrigerator/freezer control (P<0.001), vegetable/fruit disinfection (P<0.001), thawing (P<0.001), heating temperature (P<0.001), cleaning/disinfection (P<0.01), and personal hygiene (P<0.05). The frequency of hygiene education had a significant effect on the performance levels for refrigerator/freezer control (P<0.001), vegetable/fruit disinfection (P<0.001), thawing (P<0.001), heating temperature (P<0.001), cleaning/disinfection control (P<0.001), food supply control (P<0.05), and personal hygiene (P<0.05). From these results, to increase the sanitation quality of contract foodservice operations, hygiene practice levels need to increase and hygiene education systematically should be enforced for foodservice employees.

With recent advancement in informational sciences, educational systems are undergoing a revolutionary facelift on how students attain their education. These developments have diminished the traditional method of teaching and learning and have improved the overall quality of the educational environment. They have also ignited the birth of cyber-education in which students have the flexibility and responsibility on what and when to study, thus providing a greater freedom to control one's education. Cyber-educational environment not only requires physical hardware but also an organizational structural component and most importantly, a software component that drives and gives the student management power to tailor their studies based upon their educational requirements. Due to the fact that individuals learn and develop at different rates, one of the important features of a cyber-educational program will be its ability to adjust and customized to individual needs and requirements. In this thesis, a novel software which encompasses these ideas was designed and developed. This program allows the individual more flexibility and management of courses based on their ability and needs. Because the software customizes to one's ability and it allows the student to advance at a more comfortable pace, it boosts the student's confidence and desire to learn. In the future, new and improved programs similar to the one developed here will further enhance the cyber-educational environment and will undoubtedly improve the overall quality of student's education.

In this paper, we propose a predictive resource metric region (RMR) based radio resource metric estimation (RRME) mechanism, which utilizes a resource metric mapping function (RMMF), both of which permit efficient inter-working between the physical layer and higher layers for envisaging multimedia service applications over a CDMA communication system platform. The RMR can provide the acceptable resource region where QoS and acceptable link quality can be guaranteed with an achievable resource margin to be utilized in terms of capacity margin, the degree of confidence (DCL) of user, second-order statistics of Eb/Io. With predicted capacity margin and variance, DCL can deliver decision parameters with which an adaptive QoS based admission control can perform well taking capacity and resource availability into account in a dynamic and predictive manner. Combined with advanced techniques such as adaptive modulation or rate control and power control, the proposed mechanism can adjust the conventional stringent link quality information efficiently, and deliver accurate information of the resource availability. Thus, these can guarantee the maximization of resource utilization of multimedia service applications.

Purpose: To evaluate the effects of a logotherapy education program. Methods: A nonequivalent control group, non-synchronized design was conducted with a convenience sample of 29 children with cancer. The experimental group (n=17) participated in the logotherapy education program which consisted of 5 daily sessions for one week. The control group (n=12) received the usual nursing care. The effects were measured using suffering, adolescent meaning in life (AMIL), and spiritual well-being (SWBS) scales. Results: There were significant differences in suffering (W=153.00, p<.05) and meaning in life (W=78.00, p<.05) between the experimental and control groups. However, there was no significant difference in spiritual well-being (W=136.50, p>.05). Conclusions: Logotherapy was effective in reducing suffering and improving the meaning in life. Logotherapy can be utilized for adolescents with terminal cancer to prevent existential distress and improve their quality of life.

The purpose of this study was to investigate the effects of a nutrition education and exercise on nutritional status in hemodialysis patients, with regard to quality of life (QoL), and fatigue. The subjects were divided into two groups : an educated (E) group (11 men and 9 women) and a non-educated (NE) group (7 men and 22 women). The educated group received a nutrition education and a regular exercise program for 3 months. Data on anthropometric indices and biochemical parameters were obtained from medical records. Dietary habits and nutrient intake were assessed through questionnaires and three-day food records. QoL (through the SF-36 questionnaire) and fatigue (measured by a visual analogue scale questionnaire) were assessed before and after the interventions. Dietary habit scores regarding food variety and fluid intake control significantly increased (P<0.05) after the nutrition education. Furthermore, the intake of total energy, carbohydrates, Fe, and vitamin A significantly increased (P<0.05). Vitamin C intake also significantly increased (P<0.01). Hb levels decreased whereas TG levels increased in the NE group. BUN levels decreased in the E group. After the nutrition education, QoL aspects, such as feelings of pain and general health, and the total score significantly increased (P<0.05) and the level of fatigue score decreased (P<0.01). The results of this study indicate that nutrition education and exercise for hemodialysis patients provides changes in dietary habit, daily nutrient intake, biochemical parameters, QoL, and the level of fatigue. Therefore, nutrition education and exercise help improve nutritional status and QoL.
