Silikon Protez Kullanılarak Rekonstrüktif Meme Cerrahisi Uygulanmış Hastada Minimal İnvaziv Sinüs Venozus Defekti Onarımı

Atrial septal defect is one of the most common congenital cardiac anomalies in adulthood. Advances in minimally invasive surgical approaches result in an increased use of these techniques in selected patients. Atrial septal defect closure with minimal invasive surgery through right anterior thoracotomy is one of the first chosen treatment methods with reliable results and high patient satisfaction especially in young ladies. In this paper, we present the repair of sinus venosus defect with minimal invasive methods in a patient whom underwent breast reconstruction using a silicone prosthesis three years ago. The operation through right anterolateral minithoracotomy approach was successful and cosmetically uneventful even in the presence of a complex atrial septal defect and the silicone breast prosthesis in the surgical area.
Trust-Management, Intrusion-Tolerance, Accountability, and Reconstitution Architecture (TIARA)

Abstract : This report describes the Trust-management, Intrusion-tolerance, Accountability, and Reconstitution Architecture (TIARA) system, a broad design effort including novel computer architecture, operating system and application middleware. TIARA illustrates that a highly secure computer system can be designed without sacrificing performance. TIARA involves three major sub-efforts: A hardware security tagged architecture (STA) that tags each word of the computer's memory with metadata such as the data type and compartment of the data. The STA hardware enforces access rules controlling which principals are allowed to perform which operations on which data. This allows the construction of a novel Zero-kernel Operating System (ZKOS) that has no single all privileged kernel and that provides strong guarantees against penetration. Finally TIARA provides a level of application middleware that enforces architectural level constraints and maintains the provenance of application data. All common exploits are preventable by the TIARA architecture and this incurs only a minor increase in chip area.
The Effects of Target Location Uncertainty in Game Theoretic Solutions to Optimal Trajectory Formulations

Abstract : The integration of a variety of Intelligence, Surveillance, and Reconnaissance (ISR) assets is vital to the acquisition of knowledge critical to battlefield success. Missions performed by a penetrating Unmanned Aerial Vehicle (UAV) are of particular interest. The environment in which UAVs must operate includes Surface-to-Air Missile (SAM) sites with extended ranges, among other threats. SAM location uncertainty, terrain obscuration, and radar/sensor capabilities all contribute to the complexity of the situation. This thesis provides a game theoretic approach to determine optimal UAV strategies against enemy SAM sites. It is shown that most characteristics of the UAV or SAM have negligible effects on both image quality (Iq) and probability of kill (Pk) (probability of the SAM shooting down the UAV). Instead, SAM location uncertainty has the largest influence. After only 0.5 miles of uncertainty, the Pk of a UAV assuming perfect knowledge of the SAM location rises to 0.56. When the uncertainty rises to about four miles, the Pk rises to 0.99. When the UAV takes uncertainty into account, the results are not much better. Assuming that the SAM may be at one of three possible locations, the result is an average Pk of 0.49 or 0.79, depending on which optimization routine was used. Extending this situation to five, seven, and nine possible SAM locations results in an increase in Pk to 0.99 at seven locations. An even more realistic scenario involving the UAV optimizing a path through a large area of varying probabilities results in an 85% chance of getting shot down if the SAM is located within a five-mile radius of the center of the area. Outside of this area, the UAV is guaranteed to get shot down with a Pk of 0.99. Other techniques and methods must be explored and used in combination with Radar Cross Section (RCS) management to ensure the continuing collection of valuable ISR imagery in the coming years.
Synthesis of Porous Fe/C Bio-Char Adsorbent for Rhodamine B from Waste Wood: Characterization, Kinetics and Thermodynamics

In the past decades, dyes waste waters produced from industries have become a major source of environmental pollution causing the destruction of aquatic communities in the ecosystem and greatly threatened human health. Herein, a novel magnetic adsorbent was synthesized by carbonizing iron (III) 2,4-pentanedionate (Fe(acac)3) pre-enriched forestry waste wood at a pyrolysis temperature of 1000 °C. The characterization of the adsorbent conducted via SEM, EDS, VSM, XRD, XPS, and FT-IR spectroscopy. The adsorption trend followed the pseudo-second order kinetics model. The corresponding adsorption performance was efficient with an equilibrium time of only 1 min. Affect factors on the adsorption performance, such as adsorbent dosage, contact time and temperature, were investigated. The magnetic bio-char showed a high adsorption capacity and an efficient adsorption toward RhB, implying great potential application in the treatment of colored wastewaters.
Emitter Location Using Bearing Measurements from a Moving Platform

Abstract : An algorithm is derived for determining for the location of a stationary emitter based upon a number of angular measurements from a moving platform. It is referred to as the asymptotic algorithm and is particularly useful when there is appreciable error in the angle measurements. It is restricted to platform motion which generates a base line small in comparison to the range from the platform to the emitter. Under there conditions better results are obtained than from the standard least squares distance algorithm. This is accomplished with virtually the same amount of memory and computer logic. An algorithm that obtains emitter velocity as well as position is also given in the report. This algorithm, which requires a nonlinear maneuver by the platform, gives useful results when the system has good direction-finding accuracy and a capability for recording the time of a measurement. Typical results for both algorithms are presented in tables from which it is possible to judge the merits of the method for a particular application.
Confirmatory Factor Analysis of Work Attributes of Pharmaceutical Sales Representatives during COVID-19 in Nigeria

The purpose of this study was to investigate the validity of exploratory factor analysis (EFA) study on the work attributes of pharmaceutical sales executives in Nigeria using confirmatory factor analysis (CFA), and furthermore to evaluate the relative importance of the work attributes. An analytical study design used a 13-item, 5-point Likert scale questionnaire administered to 226 pharmaceutical sales executives using a simple random sampling method. Data analysis using the Statistical Package for Social Sciences (SPSS) and Analysis of Moment Structures (AMOS) with a significance level set at p<0.05. The measurement model was evaluated using the maximum likelihood method. Model fit criteria measures for CFA were satisfactory (CMIN/df=2.297; NFI=0.017; TLI=0.905; CFI=0.950; RMSEA=0.064). The study showed that the most dominant attribute was involvement in community education programs with a regression coefficient of 0.892, and the least was limited access to customers (0.446). Convergent validity measures were acceptable. Divergent validity can be enhanced by including more items. The study confirmed the validity of the EFA study outcomes obtained from the previous research work.

The expression of cerebrospinal fluid pentraxin-3 in patients with hemorrhagic stroke

Background: There exists brain tissue inflammation and endothelial function damage in stroke. Method: We investigated serum and cerebrospinal fluid (CSF) levels of PTX3, HSP70, VEGF, IL-6, CRP in patients with stroke, this study was conducted on 85 standard stroke patients during 2015-2016, include ischemic stroke (IS) group (52 cases) and hemorrhagic stroke (HS) group (33 cases). The patients without inflammatory and neurological disease were the control group (20 cases). The levels of PTX3, HSP70, VEGF, IL-6 and CRP in serum on the 1th, 5th and 14th day after admission were measured and compared them with that in cerebrospinal fluid, NIHSS and Barthel score were also performed for assessing patients with HS. The results showed that the serum levels of PTX3, HSP70, VEGF, IL-6, CRP with HS were higher than that with IS patients (P<0.001, P=0.16, P=0.08, P=0.12, P<0.001, respectively), and PTX3 level began to fall after 14th day (P=0.015). The cerebrospinal fluid of PTX3, HSP70,VEGF and IL-6 levels in patients with HS were higher than that of normal control group (P=0.002, P=0.003, P<0.001, P<0.001, respectively). The levels of PTX, HSP70, IL-6 in cerebrospinal fluid were higher than that in the serum (P=0.026, P<0.001, P<0.001, respectively), and VEGF, CRP instead (P=0.011, P<0.001, respectively). The level of PTX3 in cerebrospinal fluid was positively correlated with IL-6 in patients with HS (P<0.001), PTX3 and IL-6 in patients with HS were positively correlated with patients' NIHSS score (P=0.007, P<0.001, respectively), and negatively correlated with Barthel index score (P=0.023, P<0.001, respectively). Inflammation and endothelial damage were more severe in patients with HS. The levels of PTX3 and IL-6 in cerebrospinal fluid could assess the severity, progression, and prognosis of HS. PTX3 may be a potential biomarker in HS, it could provide potent basis for doctors to select appropriate treatment measures as soon as possible.
THE EFFECT OF COMMUNICATION TECHNOLOGY ON THE RELATIONSHIP BETWEEN ORGANIZATIONAL ENVIRONMENT AND ORGANIZATIONAL STRUCTURE: STUDY IN BANKING INDUSTRY

This study examines the moderating effect of communication technology on the relationship between organizational environment and organizational structure. Responses from 94 managers (59% response rate) were collected through questionnaire that had been distributed to 32 banks in Pekanbaru, Riau Province, Indonesia. Using a multiple regression analysis, the results show that the interaction of environmental dynamism and communication technology has a negative effect on organizational structure (formalization, complexity and integration). This study also found that the relationship between environmental complexity and centralization of organizational structure was moderated by communication technology. Meanwhile, communication technology has a positif effect on the relationship between environmental complexity and organizational structure (complexity and integration). This study provides further evidence on the importance of communication technology to organizational structure.
A VLSI Architecture for the Node of Wireless Image Sensor Network

This paper proposes a novel design of VLSI architecture for the node of wireless image sensor network. This architecture aims at the SoC (System on a chip) im- plementation and is composed of a general purpose em- bedded processor and several dedicated hardware accel- erators for image processing and wireless communication. The hardware implemented Image processing unit (IPU) adopts an innovative image processing approach which concludes Bayer Color fllter array (CFA) pre-processing and lossless JPEG compressing. The IPU can process 5 frames/s (VGA full color resolution) under a 16 MHz system clock, reaching a 2.6»4.7 bits/pixel compression rate with the PSNR larger than 46.3dB. The hardware implemented Wireless communication unit (WCU) exe- cutes computing intensive and timing critical tasks of the IEEE 802.15. 4 Media access control (MAC) layer, which can achieve high performance and low power consumption on wireless operations compared of software implementa- tion. Furthermore, low power design and techniques are employed to extend battery life, resulting in 45mW maxi- mum system power consumption when the system is in the full working mode (i:e. processor, IPU and WCU are ac- tive simultaneously). The proposed architecture has been proto-typed on an FPGA system and fabricated in 0.18"m CMOS process.
Methodology for Value-Driven Enterprise Architecture Development Goals: Application to DoDAF Framework

Abstract : The Department of Defense Architectural Framework (DoDAF) describes 29 distinct views but offers limited guidance on view selection to meet system needs. This research extends the Value-Driven Enterprise Architecture Score (VDEAScore) from a descriptive, evaluation protocol toward a prescriptive one by evaluating each DoDAF view and its contribution to the overall objective of the completed architecture. This extension of VDEA is referred to as VDEA Development Goals (VDEA-DG). The program manager or other decision-makers may use this insight to justify the allocation of resources to the development of specific architecture views considered to provide maximum value. This research provides insight into the Joint Capabilities Integration and Development System (JCIDS) process and policy requirements. Existing guidance of a static list of views prior to DoD milestone approval detracts from the creation of vital architecture for system success. This research shows overlap between the most important views for the considered architecture project and the JCIDS requirements and identifies areas for JCIDS policy improvement. This research also identifies areas where DoDAF does not directly support the creation of capabilities. With additional information on the resources required for creating individual views, the tool could be expanded to identify an optimal build sequence given resource constraints.

With the various tests conducted through the aid of multiple data sets, the system yielded an accuracy rate of 94.18%. The system is proposed to be implemented at the University of Mindanao, Matina Campus, Davao City, Philippines, with the target of automating the process of vehicle identification of the institution.
Deswelling of hardwood kraft pulp fibers by cationic polymers

The effect of cationic polymers on the degree of swelling of unbleached hardwood kraft pulp fibers of different degrees of beating has been studied. Two highly charged polymers were used, one of low (9 103) and one of high ( 2 105) molecular mass. The deswelling of the pulp fibers by both polymers is substantial, but larger in the case of the low molecular mass polymer which has access to all charged groups. The high molecular mass polymer has access only to the charges on the fiber surface. The deswelling of the pulp fibers is caused by an ion-exchange reaction between the cationic polyelectrolyte and the cationic counterions to the ionic groups in the pulp fiber cell wall. Fiber swelling was characterized by WRV (Water Retention Value) measurements. Wet pressing was studied using a dynamic compression apparatus. The increase in maximum solids content reached during wet pressing shows a good correlation with the decrease in WRV upon polymer addition. An increase in solids content of 5% or more after pressing was observed for highly swollen fibers. Sheets made from pulp deswollen by cationic polyelectrolyte did not lose their strength to the extent expected from the decrease in WRV. The fiber flexibility introduced by beating is important for sheet strength and the strength increase due to this increased flexibility is only partly lost on deswelling. It is indicated by trials on an experimental paper machine that in a practical papermaking situation the increase in maximum solids content reached during pressing as a result of the addition of cationic polyelectrolyte is substantially lower than that observed in laboratory trials. This can be explained by the fact that a higher ionic strength gives a lower initial WRV of the pulp and that there is a reaction between the added cationic polymer and anionic substances dissolved during the beating operation.
Learning Styles & Academic Performance of Teacher Education Students

Individual differences can be attributed to learning styles across students. It is the goal of this research to determine the students’ preferred learning styles and how well they performed academically. This study is a descriptive-correlation method of research on the learning style and academic performance of teacher education students. The results revealed that: First-year teacher education students have varied learning styles with social learning style as the most dominant. This implies that the first-year teacher education students prefer to learn in groups or with other people; The rating of the first-year teacher education students ranges from 1.6-2.0 which is equivalent to “very good” in the adjectival rating based on the grading system of the university, and The correlation analysis using the Pearson’s Product Moment Correlation of Coefficient result to a p-value which is greater than the level of significance (0.05) for all learning styles which means that there is no correlation between students' chosen learning techniques and their academic success.
Roux-en-Y Reconstruction Following Distal Gastrectomy Reduced Endoscopic Reflux Esophagitis in Older Adults: Propensity Score–Matching Analysis

This study aimed to examine the functional outcomes of Roux-en-Y (RY) and Billroth I (BI) reconstruction methods following distal gastrectomy in patients ages ≥75 years with gastric cancer. RY and BI reconstructions are commonly performed after distal gastrectomy. However, no study has compared the 2 procedures in older adults. We identified older patients who underwent RY (n = 103) or BI (n = 71) reconstruction following distal gastrectomy from 2011 to 2018 in our database. Patients in the RY and BI groups were matched by propensity scores, and each group included 62 patients. We compared short-term surgical outcomes and clinical findings at 1 year postoperatively. Additionally, risk factors for endoscopic reflux esophagitis following distal gastrectomy were evaluated. Reflux esophagitis, bile reflux, and remnant gastritis were significantly less frequent in RY reconstruction than in BI reconstruction. Moreover, both BI reconstruction and preoperative hiatus hernias were independent risk factors for postoperative endoscopic reflux esophagitis. Although the incidence of postoperative surgical complications following RY and BI was similar, RY was found to cause delayed gastric emptying more frequently than BI. RY reconstruction is a favorable procedure to prevent reflux esophagitis in older patients, particularly in those with hiatal hernia.
Bombardier ORBITA: predictive asset management

For many years, the on-board diagnostic capability on trains has grown rapidly and sometimes so fast that no one actually knows what to do with all the data that is being produced by the on-board systems. One could argue that the result is a massive amount of data, but not much in the way of information. In order to make use of the current diagnostic data produced by today's rolling stock and in order to further develop the potential of that data, Bombardier has developed a system called Bombardier ORBITA. Bombardier ORBITA has been developed by Bombardier with the aim of helping operators to increase fleet utilisation, improve reliability and availability and ultimately improve the passengers' overall journey experience. Advancements in on-board systems and global communications technology have paved the way for ORBITA, as they enable rolling stock to provide 'real-time' performance-related information directly from the vehicle to the operator or maintainer. Bombardier has taken this capability a stage further with ORBITA, which utilises teams of control centre based system experts who interrogate the data, liaise with the depots and cross-reference information from Bombardier's extensive global fleet database to establish patterns of equipment performance. This enables them to diagnose and identify potential issues before they occur, as well as respond quickly and knowledgeably to in-service faults. Typical systems which can be monitored include HVAC, doors, brakes, CCTV, propulsion and electrical equipment. Furthermore, ORBITA can be used to pinpoint issues relating to, for example, energy/fuel consumption, passenger loading and infrastructure problems. Bombardier ORBITA has been rolled out on many fleet in Europe. The First ScotRail (Turbostar DMU) fleet was the first fleet on which the Orbita technology was used. Orbita is also being deployed on the Vlocity fleet DMUs in Melbourne).
