Most high efficiency silicon solar cells use a passivated selective emitter. It have been an important research subject for crystalline silicon solar cells for decades. It is being used in production for high efficiency solar cells. Most of the selective emitter process require expensive extra masking, etching steps, and a double diffusion process making selective emitters not cost effective. In this paper, we study method for single diffusion step selective emitter process as an alternative to not cost effective double diffusion process. Cost effective selective emitter that the efficiency should be increased significantly (mare than 0.2%) and that the process should simple, robust and cheap.

Activating e-commerce, studies about trust of business acquaintance are actively made. This study measured the effect of trust transfer setting up 6 situations according to linking direction, design standard and grasping their trust changes for surveying trust transfer on online. The result is that trust transfer becomes different in accordance with the linking direction of hyperlink. In other words, setting up target site as comparative subject, it is more reliable than single site. Setting up source site as comparative subject, trust changes are slight. This study is composed of 6 good site and 6 poor site. And trust transfer by hyperlink on online is consistent, especially trust transfer is affected by not source site but target site. If target site is poorer than source site, trust transfer originate definitely. So we can draw consistent conclusion that it rate higher than single site. On the other hands, if targer site is better than source site, trust transfer occurs not inter-website. Instead, affected by human mentality, it rates good site higher by conformity reversion.

Purpose: The purpose of this study is to investigate whether dual-hemisphere transcranial direct current stimulation (tDCS) could induce more cortical activity, compared to single-hemisphere, using functional MRI (fMRI). Methods: One right-handed healthy subject was recruited. Three phases of dual-hemisphere tDCS (i.e. anodal tDCS over the left-dominant primary sensoriomotor cortex (SM1) and cathodal tDCS over the right-non dominant SM(1) were consecutively delivered on to a subject, during fMRI scanning. The voxel count and the intensity index in the averaged cortical map were analyzed among the three tDCS phases. Results: Our result showed that cortical activation was observed on all the three phases of the dual-hemisphere tDCS. Voxel count and intensity index were as following; 912 and 4.07 in the first phase, 1102 and 3.90 in the second phase, 1031 and 3.80 in the third phase. Conclusion: This study demonstrated that application of the dual-hemisphere tDCS could induce cortical activity and maintain to recruit cortical neurons. Our findings suggested that application of dual-hemisphere tDCS could produce efficiency of the ongoing tDCS effect to facilitate cortical excitability.

PURPOSE: This study examined the effects of high-intensity (HI) muscle strength training and stretching exercises on muscle strength, spasticity, postural alignment, and participation in the activities of daily living (ADL) in an adolescent with cerebral palsy (CP). METHODS: The study used a single-subject design with a 16-week follow-up. After a three-week intervention-free period, a participant underwent five data collection sessions for the baseline measurements. Subsequently, stretching and HI strength training occurred three times weekly for 48 sessions, with the outcome measures collected weekly post-treatment. Final measurements were taken the day after the last session, and a follow-up assessment occurred six weeks post-study to assess the learning effects. RESULTS: After 16 weeks of treatment, the participant exhibited improved targeted muscle strength and postural alignment without increased spasticity. On the other hand, no significant change in participation in the ADL was observed. CONCLUSION: The research findings suggest that HI strength training and stretching exercises may contribute to improvements in muscle strength and body alignment without increased spasticity in an adolescent with CP, but it may not have a significant impact on participation in ADL.

PURPOSE: The purpose of this study was to determine the effect of corrective exercise on hip joint range of motion, lower limb alignment, radiographs of hip and knee joints, and quadriceps muscle activity in a patient with knee joint valgus deformity. METHODS: A single-subject A-B-A experimental design was used to determine the effects of therapeutic exercise. The single-subject was a 27-year-old male, who presented with knee joint valgus deformity. Corrective exercise program was performed for 40 min/day twice a week for 12-week. Range of motion (hip flexion, extension, abduction, adduction, internal rotation, and external rotation), lower limb alignment test (Q-angle, rear foot alignment, and leg length), standing anterior-posterior radiographs (neck shaft angle and knee joint space), and quadriceps muscle activity of both lower limbs were measured before (A 1), after 6 weeks (B 1) and after 12-weeks (B 2) of corrective exercise and after 6 weeks of exercise completion (A 2). RESULTS: Hip range of motion increased in all directions of both sides at B 2 and A 2 compared to at A 1. Q-angle of both side and leg length discrepancy decreased at B 2 and A 2 compared to at A 1. Neck shaft angle and knee joint space of both sides improve at B 2 and A 2 compared to at A 1. Quadriceps of both side muscle activities improved at B 2 and A 2 compared to at A 1. CONCLUSION: We demonstrated that corrective exercise increases range of motion, and improves lower limb alignment and muscle activity in a patient with knee joint valgus deformity.

This case report described a single case of adult stoke patient due to Moyamoya disease through long-term follow-up observation, which included his demographics, brain images, and change of motor function and functional activities. The subject was the 54-year-old male diagnosed with left hemiparesis from a stroke due to multifocal encephalomalacia in both hemispheres. At the time of the stroke attack, he took brain surgery intervention including external ventricular drain. Physical and occupational therapy for stroke rehabilitation were admitted including muscle strengthening exercises, functional activity/ADL training, neurofacilitative techniques with bobath or proprioceptive neuromuscular facilitation concepts, and compensatory strategy. Patient's MRI showed that right frontal lobe, right peri-ventricular area, left parietal, and left occipital lobes were damaged, and MRA showed that abnormal collateral vessel was richly developed in both hemispheres by occlusion of proximal internal carotid arteries in both sides. His motor strength was improved from poor to good grade in all of upper and lower limb motions, that MBC was improved from stage 1 to stage 5. In FAC and barthel index, at the initial evaluation, he could not perform any functional movement, but his FAC and barthel index were on 3 and 14 points at present, respectively. During long-term follow-up for approximately 4 years, the subject's functional motor ability was improved, as similar with recovery progression of usual stroke patient. We believe that this single case report will provide clinical information and concern regarding Moyamoya disease with physical therapist, in terms of such as epidemiology, pathogenesis, diagnostic procedures, clinical features, recovery process, and prognosis.

Purpose: This study investigates the effects of task-oriented training for a left trunk flexion pattern using real-time ultrasound imaging in a stroke patient with unilateral neglect symptoms. Methods: This study used the ABA experimental design, which is a single-subject research method among individual case research methods. For the ABA experimental design, changes in the degree of unilateral neglect, balance ability, and the thickness of the lateral abdominal muscle were visually analyzed during the baseline process, in the intervention period, and after the intervention. The experiments were performed 24 times in total for 8 times in each of the 3 periods. The unilateral neglect was measured using the Albert test, balance ability was measured using the Berg balance test, and the thickness of the lateral abdominal muscle was measured using ultrasound imaging. The subject was a 50-year-old male patient with unilateral neglect caused by right cerebral hemorrhage. He performed task-oriented training for a voluntary left trunk flexion pattern using real-time ultrasound imaging during the intervention period. Results: The result of comparing the data collected during the intervention period with the data point average of the baseline process showed that balance ability improved and the tendency line was above the baseline. The tendency line of unilateral neglect was below the baseline and showed a decreasing tendency. The thickness of the lateral abdominal muscle showed an increasing trend and the tendency line was above the baseline. Conclusion: The results of this study suggest that the task-oriented training for left trunk flexion pattern using real-time ultrasound imaging has a beneficial effect on balance ability, the degree of unilateral neglect, and the strength of the lateral abdominal muscle in unilateral neglect patients.

Objective : The aim of this study is to investigate the curative effect of Bee Venom Acupuncture Therapy for pain and limited R.O.M (range of motion) of shoulder in stroke patients. Methods : The subjects of this study were 6 patients with shoulder pain in stroke sequelae. Routine Oriental Medical programs (Acupunture, moxibustion, herbal medicine and physical therapy) were maintained for each subject throughout this study. Single subject ABABAB design was adopted. Each period was 4 days as a rule. Only during the treatment period, Bee Venom Acupuncture Therapy was provided as intervention at the acupoints of LI15(Gyeonu),　TE14(Gyeollyo), GB21(Gyeonjeong), LI14(Bino). The change of pain was measured with a Visual Analogue Scale(VAS). The pain threshold was measured using pressure algometer at the same acupoints where Bee Venom Acupuncture Therapy was provided. And the R.O.M of shoulder joint (flexion, extension, abduction, adduction, external rotation, internal rotation) was measured as well. Analysis was performed by Bayesian analysis using WinBUGS for the comparison of treatment(Bee Venom Acupuncture Therapy) and non-treatment. Results : The median overall improvement for difference in VAS was -2.219(-3.213, -1.175), for difference in external rotation of shoulder R.O.M was 9.992(-2.298, 18.49), for difference in tenderness score of LI14(Bino) by pressure algometer was 5.05(0.6283, 7.762). 95% credibility intervals being shown in brackets. However, the median overall improvement for difference in the other measurements was not significant. Conclusion : This study suggests that Bee Venom Therapy may be applicable to decrease pain and improve R.O.M of shoulder in hemiplegia patients with stroke. Further elaborated single subject designs need to be accumulated to confirm the effects of Bee Venom Acupunture Therapy on shoulder pain in patients with stroke sequelae.
