Shadow Projection: Elicitation of Emotional Response
The study aimed to determine the elicitation of individual emotional response through shadow projection, and to recognize if there is a significant difference between male and female emotional response upon presentation of such stimuli. The descriptive research design was used to establish the affective component of the target respondent. The researchers believed that projection of shadows or series of animated shadows can be a tool to elicit emotional arousal or response from individual when expose to shadow stimuli. Respondents were selected using the stratified random sampling method among high school students (N-131), and were assembled for 3-5 minutes visual presentation of a themed animated shadow using a projector device. Series of shadows are projected and after each session, students were requested to accomplish questionnaire which is the main data gathering tool to confirm whether the projected shadows have an emotional effect. In the course of the shadow presentation, students-respondents were earnestly watching each session coupled with occasional burst of noise in reaction to projected shadow scenes, suggesting that the shadow stimuli have emotional effects. Results revealed that shadow projections have an effect on students-respondents, signifying an elicitation of emotional response. Statistically, significant difference between male and female responses is apparent.

Pediatric COVID-19 Encephalitis
Background: Neurologic complications of COVID-19 in the pediatric population have been reported in a limited number of reports. There have been reports of COVID-19-associated encephalitis in pediatric cases along with neuroimaging findings revealing involvement of some parts of the nervous system. We present the first case of pediatric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) - associated encephalitis targeting the parietal lobes.
Case: A 14-year-old morbidly obese Hispanic male with no past medical history presented to the hospital for new onset seizures. Family reported exposure to his COVID-19 positive mother, a one-week history of fever, and a three-month history of decreased oral intake, vomiting, diarrhea, weight loss, and decreased urine output. He tested positive for SARS CoV-2 six days prior to admission. Patient was admitted to the intensive care unit. Blood pressure was 169/101. Labs included elevated blood urea nitrogen and creatinine, 102mg/dL and 26 mg/dL, respectively, consistent with severe kidney injury. Brain MRI revealed restricted diffusion on the bilateral subcortical white matter of the parietal lobes. Electroencephalogram revealed mild to moderate encephalopathy. After treatment with convalescent plasma and dexamethasone there was complete neuroradiologic abnormality resolution with dramatic clinical improvement.
Conclusions: This case highlights a new brain target of the SARS-CoV-2 in pediatric patients. The temporal improvement in symptoms after administration of convalescent plasma and dexamethasone raises interest in their use for management of SARS-COV-2 infection in pediatric patients. Further research into these findings is important for predominately Hispanic communities which have been disproportionately affected by the pandemic
Implementation of a 4-bit Ripple Carry Full Adder of Mirror Design Style Using Synopsys Generic 90nm Technology on a Full-Custom and Semi-Custom Design
The most frequently used component in the datapath block and the speed-limiting element is the adder. Because of this, it is essential to optimize the adder knowing it has a big impact on the overall system performance. In addition to that, adders are a very important subsystem in digital designs, thus, taking care about its performance must be spotted. By manipulating the transistor sizes and circuit topology, the speed can be optimized. A circuit of a CMOS (Complementary metal oxide semiconductor) 4-bit RCA (Ripple Carry Adder) is presented. The proposed adder cell refers to the CMOS adder class executed on CMOS mirror design style that has a smaller area and delay compared with the static adder implementation of the full adder. By simply cascading full-adder blocks, one obtains a Ripple-Carry Adder which perhaps the simplest to implement than that of the other carry adders. Creating the full adder in schematic diagram is a part of Pre-simulation. It incorporates the construction of CMOS transistors and connected through the use of wires. Widths and lengths of the transistors are the crucial parts in designing to place and route connections easily. Layout diagram is the equivalent of the schematic diagram but more on a detailed part and it should be the same as the transistor based circuit. With the aid of the verification processes such as DRC (Design Rule Check) and LVS (Layout versus Schematic), it can give an assurance that both the schematic and layout diagrams are similar and functioning properly
PALM VEIN RECOGNITION SYSTEM USING DIRECTIONAL CODING AND BACKPROPAGATION NEURAL NETWORK
This paper proposes an effective palm vein recognition system by using back-propagation neural networks for biometric application. In the recent years, because of the high development cost, vein pattern is not popular biometric as compared to other biometric system like fingerprint, palm print, face and iris. But, the advantage of palm vein on classical biometric are the low risk of falsification, uniqueness, strong immunity to forge and stability.
Biometric palm vein images are acquired using near infrared illuminated LEDs and IR-Sensitive web camera from 40 persons of different gender and ages. Firstly, the palm vein region of interest (ROI) was extracted from hand images and then applied with gamma correction and local ridge enhancements (LRE) that were applied to the 100 x 100 pixels image and palm vein pattern images in order obtain the correct contrast and sharpness of the image without excessively increasing the noise. The palm vein features were extracted from the enhanced region of interest for each sample using Sobel directional coding scheme in the four directions (0º, 45º, 90º, 135º). The extracted sobel images were converted to gray-scale image using Otsu's thresholding method. The resulting gray-scale images were divided into 20x20 sub-regions before the feature matching. Mean absolute deviation (MAD) is implemented to these sub-region as the feature vectors. Those feature sets is the input on the back-propagation neural network. According to the results, the feature matching method can achieve up to 98.75% of correct classification rates
An evaluation on the clinical performance of the senior radiologic technology interns of De La Salle - Health Sciences Campus during School Year 2005-2006
The descriptive method of research was used in the study. The respondents were composed of eight (8) clinical supervisors, nine (9) clinical instructors and 79 senior RT interns and they were selected using stratified sampling technique. The researchers formulated a self-made instrument that evaluated the clinical performance evaluation of the senior RT interns during school year 2005-2006. In the analysis of data gathered, the mean, standard deviation, Friedman Test, percentage and frequency were used. From the findings, the following conclusions were drawn: (1) Most of the senior RT interns were male. The hospital which had the most number of interns was Philippine Orthopedic Center (POC) and the least distribution of interns was noted in the Lung Center of the Philippines (LCP) and Manila Doctors Hospital (MDH); (2) The obtained mean of grade of the clinical performance was verbally interpreted as very good. This showed that the interns performed well in their respective hospital assignment; (3) The null hypothesis of no significant differences in the evaluation of the three (3) groups of respondents on the clinical performance of the senior RT interns was rejected. The alternative hypothesis that there is a significant difference in the evaluation of the three groups of respondents on the clinical performance of the senior RT interns is accepted
