The emerging of ubiquitous computing and healthcare technologies provides us a strong platform to build sustainable healthcare applications especially those that require real-time information related to personal healthcare regardless of place. We realize that system stability, reliability and data protection are also important requirements for u-healthcare services. Therefore, in this paper, we designed a u-healthcare system which can be attached to the patient's body to measure vital signals, enhanced with USN secure sensor module. Our proposed u-healthcare system is using wireless sensor modules embedded with NLM-128 algorithm. In addition, PS-LFSR technique is applied to the NLM-128 algorithm to enable faster and more efficient computation. We included some performance statistical results in term of CPU cycles spent on NLM-128 algorithm with and without the PS-LFSR optimization for performance evaluation.

Alzheimer's disease (AD) is the most frequent age-related human neurological disorder. The characteristics of AD include senile plaques, neurofibrillary tangles, and loss of synapses and neurons in the brain. ${\beta}-Amyloid$ ($A{\beta}$) peptide is the predominant proteinaceous component of senile plaques. The amyloid hypothesis states that $A{\beta}$ initiates the cascade of events that result in AD. Amyloid precursor protein (APP) processing plays an important role in $A{\beta}$ production, which initiates synaptic and neuronal damage. ${\delta}-Catenin$ is known to be bound to presenilin-1 (PS-1), which is the main component of the ${\gamma}-secretase$ complex that regulates APP cleavage. Because PS-1 interacts with both APP and ${\delta}-catenin$, it is worth studying their interactive mechanism and/or effects on each other. Our immunoprecipitation data showed that there was no physical association between ${\delta}-catenin$ and APP. However, we observed that ${\delta}-catenin$ could reduce the binding between PS-1 and APP, thus decreasing the PS-1 mediated APP processing activity. Furthermore, ${\delta}-catenin$ reduced PS-1-mediated stabilization of APP. The results suggest that ${\delta}-catenin$ can influence the APP processing and its level by interacting with PS-1, which may eventually play a protective role in the degeneration of an Alzheimer's disease patient.

The purpose of this study was to examine the impact of balance training on the Inbody and recovery of the balance capability in stroke patient with obesity. The exercise program was to conduct obesity group and normal weight group, 22 subjects were divided equally into experimental(obesity) and controlled group(normal weight), assigned to excercise using the balance training system for 30min a day and 5 days a week. Every pre and post-experimental data of both groups were gathered by Inbody and BSS(Biodex Medical Systems) for 8 weeks. As a result, Comparing the intra-group data measured by Inbody, obesity group showed significant difference in every parameter (p<.05). In the inter-group data, every parameter showed significant difference between both groups (p<.05). Comparing the intra-group data of LOS(Limits Of Stability), obesity group showed significant difference with all parameters, except with 'Backward' and 'Left' (p<.05). In the inter-group data, 'Forward' parameter showed significant difference. Comparing the intra-group data of PS(Postural Stability), obesity group showed significant difference with all parameters (p<.05). The inter-group PS(Postural Stability) results differed significantly only with 'Med/lat'(p=.000). The above results implicate about the following conclusions that the balance training had a big effect on the Inbody and recovery of the balance capability in stroke patient with obesity.

The half-turned truncal switch (HTTS) operation has been reported as an alternative to the Rastelli or $r{\acute{e}}paration$ $\grave{a}$ $l^{\prime}{\acute{e}}tage$ ventriculaire procedures. HTTS prevents left ventricular outflow tract (LVOT) obstruction in patients with complete transposition of the great arteries (TGA) with a ventricular septal defect (VSD) and pulmonary stenosis (PS), or in those with a Taussig-Bing anomaly with PS. The advantages of the HTTS procedure are avoidance of late LVOT or right ventricular outflow tract (RVOT) obstruction, and of overstretching of the pulmonary artery. We report the case of a patient who underwent HTTS for TGA with VSD and PS, in whom there was no LVOT obstruction and only mild aortic regurgitation and mild RVOT obstruction, including observations at 12-year follow-up. Our experience with long-term follow-up of HTTS supports a solution for late complications after the Rastelli procedure.

Complete TGA is a common congenital cardiovacular anomaly, and without palliative or corrective surgery, the infant born with TGA rarely survives the first year of life. Hemodynamically, recirculated blood flow in the systemic and pulmonary circuit has a key role in systemic arterial oxygen saturation and the status of the pulmonary vascular bed. Recently a d-TGA with VSD and PS, in a 12 year old male patient had been tried for inversion of the ventricular flow with Rastelli operation. An intracardiac tunnel was constructed between the VSD and the aortic orifice to connect the ventricle to the aorta. The right ventricle was connected with the pulmonary circulation by anastomosis of an valved conduit between the right ventricle and the distal end of the pulmonary artery. During the postop, period, the irreversible renal failure, accompanied by metabolic acidosis and pulmonary edema, occured under relative stabilized cardiac performance state. The autopsy was done, which revealed diffuse infarcted area in both kidney and preserved intra & extracardiac graft constructed.

PURPOSE. This in vitro study aimed to evaluate the performance of digital intraoral scanners in a completely edentulous patient with angled and parallel implants. MATERIALS AND METHODS. A total of 6 implants were placed at angulations of 0°, 5°, 0°, 0°, 15°, and 0° in regions #36, #34, #32, #42, #44, and #46, respectively, in a completely edentulous mandibular polyurethane model. Then, the study model created by connecting a scan body on the implants was scanned using a model scanner, and a 3D reference model was obtained. Three different intraoral scanners were used for digital impressions (PS group, TR group, and CS group, n = 10 in each group). The distances and angles between the scan bodies in these measurement groups were measured. RESULTS. While the Primescan (PS) impression group had the highest accuracy with 38 ㎛, the values of 104 ㎛ and 171 ㎛ were obtained with Trios 4 IOSs (TR) and Carestream 3600 (CS), respectively (P = .001). The CS scanner constituted the impression group with the highest deviation in terms of accuracy. In terms of dimensional differences in the angle parameter, a statistically significant difference was revealed among the mean deviation angle values according to the scanners (P < .001). While the lowest angular deviation was obtained with the PS impression group with 0.185°, the values of 0.499° and 1.250° were obtained with TR and CS, respectively. No statistically significant difference was detected among the impression groups in terms of precision values (P > .05). CONCLUSION. A statistically significant difference was found among the three digital impression groups upon comparing the impression accuracy. Implant angulation affected the impression accuracy of the digital impression groups. The most accurate impressions in terms of both distance and angle deviation were obtained with the PS impression group.

DQA, a patient specific quality assurance in tomotherapy, is usually performed using an ion chamber and a film. The result of DQA is analysed with the treatment planning system called Tomo Planning Station (TomoPS). The two-dimensional dose distribution of film measurement is compared with the dose distribution calculated by TomoPS using the ${\gamma}$-index analysis. In ${\gamma}$-index analysis, the criteria such as 3%/3 mm is used and we verify that whether the rate of number of points which pass the criteria (pass rate) is within tolerance. TomoPS does not provide any quantitative information regarding the pass rate. In this work, a method to get the pass rate of the ${\gamma}$-index analysis was suggested and a software PassRT which calculates the pass rate was developed. The results of patient specific QA of the intensity modulated radiation therapy measured with I'mRT MatriXX (IBA Dosimetry, Germany) and DQA of tomotherapy measured with film were used to verify the proposed method. The pass rate was calculated using PassRT and compared with the pass rate calculated by OmniPro I'mRT (IBA Dosimetry, Germany). The average difference between the two pass rates was 0.00% for the MatriXX measurement. The standard deviation and the maximum difference were 0.02% and 0.02%, respectively. For the film measurement, average difference, standard deviation and maximum difference were 0.00%, 0.02% and 0.02%, respectively. For regions of interest smaller than $24.3{\times}16.6cm^2$ the proposed method can be used to calculate the pass rate of the gamma index analysis to one decimal place and will be helpful for the more accurate DQA in tomotherapy.

Objectives The purpose of this case study was to report a case of anorexia and fatigue after getting vaccinated COVID-19 treated based on Sasang Constitutional Medicine. Methods The patient was hospitalized for 4 days and treated with herbal medicine and moxibustion. The patient was asked to score for daily energy level out of 100 on his own and we used Karnofsky Performance Score(Karnofsky PS) on daily health status to evaluate the clinical effects. We also checked daily amount of meal and evaluated original symptoms such as insomnia, gastric discomfort, bowel movement and dysuria in four stages. Results At initial, the patient could only eat one spoon of a meal and was unable to carry on herself without any assistance, so she used a wheelchair on the day of admission. When discharged, the patient can eat half of a meal at each mealtime and perform normal activities by herself. Discussion This case demonstrates that Sasang constitutional approach to anorexia and fatigue caused by COVID-19 vaccination can be an useful treatment.

Background: There have been limited reports on the effectiveness of 5% lidocaine patches (L5Ps) for treating a few types of chronic pain. We utilized L5Ps for chronic pain patients with various diagnoses and who had incompletely responded to their current treatment regimen. This study aimed at describing the results of a retrospective review of an open-label L5P trial to assess L5Ps' effectiveness and safety for treating various chronic pain patients. Methods: The chronic pain patients with pain lasting longer than 6-month duration were offered a 2-week L5P treatment trial. The patients were maintained on their other analgesic regimens. The treatment effect was measured according to the change from the baseline visual analog scale (VAS) to the week 2 VAS. After a 2-week trial, the patients were asked if they perceived pain improvement with L5Ps by using a four-item Pain Relief Scale (1 = a lot of relief, 2 = slight relief, 3 = no change, 4 = worse pain). Results: In the combined patient population (n = 177), 2-week treatment with the L5Ps significantly improved the week 2 VAS (P = 0.000). Significant improvement in the VAS was reported by the chronic pain patients with postherpetic neuralgia, intercostal neuralgia, degenerative osteoarthritis at knee joint, and other maladies. A higher proportion of the chronic pain patients reported improving their pain by the L5Ps. Seven patients experienced mild or moderate patch-related adverse events. Conclusions: The L5P provided clinically meaningful pain relief in some refractory chronic pain patients without any severe adverse events.
