Purpose : The objective of the current study was to evaluate the impact of the Computer-Based Cognitive Rehabilitation Program (CoTras) on the cognitive function and daily living activities of elderly and adult stroke patients. Methods : Twenty stroke patients were divided into two groups comprising 10 elderly stroke patients and 10 adult stroke patients. The CoTras was applied as the intervention for 30 minutes at a time, three times a week, for nine weeks (i.e., a total of 27 times), to both groups. The Neurobehavioral Cognitive Status Examination was used to assess cognitive function, and the Functional Independence Measure was utilized to evaluate daily living activities, prior to, during, and after the intervention. Results : The CoTras was demonstrated to have a statistically significant and positive effect on the cognitive function and daily living activities of stroke patients. However, the effect of the program on the restoration of weight-shifting capacity, as a component of the daily living activities of stroke patients, was without statistical significance. The program had a greater influence on improving the cognitive function and daily living activities of elderly stroke patients than adult stroke patients. Conclusion : This study makes a meaningful contribution to the literature on the topic as the intervention was demonstrated to lead to a more significant recovery of cognitive function and daily living activities in elderly stroke patients, compared to adult patients. Therefore, it is proposed that the CoTras should be used as a clinical intervention for elderly stroke patients. Future studies that evaluate the application of the CoTras, along with other occupation-based intervention programs, are warranted.

Background: In the rehabilitation of stroke patients, regular physical activity is very important not only as a treatment for maximal functional recovery but also as a strategy to prevent the recurrence of stroke. The purpose of this study was to objectively measure the amount of physical activity in people with stroke, and to examine the differences in motor and cognitive function according to a level of physical activity. Design: A cross-sectional study. Methods: Physical activity (GENEActiv), motor function (Fugl-Meyer Assessment), cognitive function (Montreal Cognitive Assessment-Korean version), and the Korean version of Modified Barthel Index were evaluated in adult stroke patients with hemiplegia. Results: There was no statistically significant difference in the level of physical activity according to the motor and cognitive function. There was no statistically significant difference in motor and cognitive function according to the level of physical activity, but there was a statistically significant difference in the MBI (p<.01). Conclusion: As a result of the difference in the MBI according to the level of physical activity, it was found that the more moderate to vigorous physical activities are performed, the higher the independence in daily living. These results can be interpreted as that the more often you participate in physical activities such as physical therapy (gait training), the better your independence in ADL. Since regular physical activity participation of adult stroke patients can improve daily living performance, it is considered necessary to participate in physical activities such as continuous physical therapy.

Purpose: This study was to compare quality of life, sexual function, and depression between a group with sexually active women and the other with sexually inactive women who undertaken mastectomy. Methods: Participants were 106 breast cancer patients who had spouse and participated in self-help group in Gwangju, Korea. The questionnaires were consisted of Quality of Life Index-Cancer Version (Q.L.I.-C), self-rating depression scale, and Female Sexual Function Index (FSFI). Data were analyzed using the SPSS Win 14.0 K+ for descriptive statistics, t-test, ANCOVA, and MANOVA. Results: There were no homogeneity at age, job, educational years between sexually active vs. inactive groups. In sexually active group, mean age was 46.1, having job 34.5%, bachelor's degree 38.2%, and pre-menopause 79.2%; for the inactive group 49.6, 10.4%, 12.5%, and 52.7% seperately. There were significant differences in quality of life, sexual function, and depression between two groups when four covariates were controlled. The quality of life and sexual function in sexually active group were significantly higher than inactive group(p<0.001). The depression in sexually active group was significantly lower than inactive group(p<0.001). Conclusion: This study indicates that nurses are needed to counsel and intervene psychosexual approach especially sexually inactive women with breast cancer during the recovery period.

Purpose: This study was to identify the effects of oropharyngeal sensory stimulation on a functional oral intake scale, ore-pharyngeal swallowing functions, and aspiration pneumonia symptoms with nasogastric tube insertion in stroke patients. Method: This study was a nonequivalent control group non-synchronized design. The subjects or the study were 32 patients who were hospitalized in Kosin Gaspel hospital. The experimental subjects were stimulated for $10{\sim}20$ minutes, 1 time per day. The intervention was implemented for 2 weeks. Result: Participants in the experimental group significantly received a higher score in ore-pharyngeal swallowing function than those in the control group. However the participants in the experimental group only got a high score in the function oralintake scale which doesn't imply a statistical significance. In addition, they didn't geta remarkably higher score in aspiration pneumonia symptoms than those in the control group. Conclusion: This study demonstrates that oropharyngeal sensory stimulation is effective in promoting recovery oro-pharyngeal swallowing function of nasogastric tube insertions in stroke patients.

Tomographic particle image velocimetry (PIV) is a widely used method that measures a three-dimensional (3D) flow field by reconstructing camera images into voxel images. In 3D measurements, the setting and calibration of the camera's mapping function significantly impact the obtained results. In this study, a camera self-calibration technique is applied to tomographic PIV to reduce the occurrence of errors arising from such functions. The measured 3D particles are superimposed on the image to create a disparity map. Camera self-calibration is performed by reflecting the error of the disparity map to the center value of the particles. Vortex ring synthetic images are generated and the developed algorithm is applied. The optimal result is obtained by applying self-calibration once when the center error is less than 1 pixel and by applying self-calibration 2-3 times when it was more than 1 pixel; the maximum recovery ratio is 96%. Further self-correlation did not improve the results. The algorithm is evaluated by performing an actual rotational flow experiment, and the optimal result was obtained when self-calibration was applied once, as shown in the virtual image result. Therefore, the developed algorithm is expected to be utilized for the performance improvement of 3D flow measurements.

A panic state is often caused by careless computer control. It could be also caused by a kernel programmer's mistake. It can make a big problem in computer system when it happens a lot. When a panic occurs, the process of the panic state has to be checked, then if it can be restored, operating system restores it, but if not, operating system runs the panic function to stop the system in the kernel hardening O.S. To decide recovery of the process, the type of the panic for the present process should be checked. 1'he value type and the address type have to restore the process. If the system process is in a panic state, the system should be designed to shutdown hardening function In the Linux operating system. So it has to decide whether the process should be restored or not before going to the panic state.

In the digital transmission equipment, the input jitter tolerance is a function of input timing recovery circuit characteristics. Especially, in the asynchronous multiplexers, it is also a function of the frame format, the buffer sizes in the synchronizer and desynchronizer, the PLL transfer function, and operating range of VCO in PLL In this paper, a new algorithm for calculating the jitter tolerance of the saynchronous digital transmission equipment is presented. With the new algorithm, we analyzed how the above factors limit the jitter tolerance in the equipment. We also measured the input jitter tolerance for a 45M-140M multiplexing equipment, whose results show the same trend with calculated tolerance.

Purpose: This study aimed to examine the effects of mirror-neuron-system-based action observation physical training on improvements in upper extremity functions and daily living activities in chronic stroke patients. Methods: Ten chronic stroke patients were randomly selected. As a therapeutic intervention, along with conventional occupational therapy, the patients engaged in action observation physical training through repeated imitation practices after they viewed a video. The therapeutic intervention was implemented for 20 minutes, three times each week for eight weeks. A Manual Function Test (MFT) was conducted to compare upper extremity functions before and after the therapeutic intervention, and the Modified Barthel Index (MBI) was used to compare the ability to perform daily living activities. Results: Significant improvements in upper extremity motor functions and the ability to perform daily living activities were shown after the intervention. The subjects' left upper extremity motor functions and ability to perform daily living activities showed significant improvement after the intervention. Conclusion: The study's results indicate that action observation physical training based on the mirror neuron system improves chronic stroke patients' upper extremity motor functions and their ability to perform daily living activities. Therefore, action observation training has positive effects on the functional recovery of chronic stroke patients.
