Tertiary Care Centre
Authors: bharati anuradha , sharma pallavi , mahajan sachit , Raina Bhavani , Kai Sanjay
Published: November 2020

Background and Objectives : Ocular trauma can lead to
development of cataract when natural lens is damaged by
either blunt or penetrating injury. The management of
traumatic cataract follows the same principle as for senile
cataract but associated damage to ocular tissues and several
post-operative complications may lead to suboptimal visual
outcome. This study was conceptualized to evaluate the visual
outcomes following management of traumatic cataracts.
Material and Methods : This prospective, longitudinal study
was conducted on 80 patients with traumatic cataract in
tertiary care centre. Patients were managed surgically and were
followed up for a period of six months. Visual acuity was
measured at every follow-up visit and any post-operative
complications were noted and managed, accordingly. Final
visual acuity was assessed at the end of six months.
Results: Maximum cases of traumatic cataract (53.75%) were
observed in age group of <20 years with male to female ratio
of 2.63:1. Maximum patients (92.15%) were implanted
posterior chamber intraocular lens, either as a primary or
secondary procedure. Uveitis and posterior capsular
opacification were most common post-operative complications
(30%) and 68.75% cases achieved a final visual acuity of 6/6-6/
18 at the end of six months.
Conclusions
Traumatic cataract is an important cause of ocular
morbidity specially in young patients. Surgery in cases of
traumatic cataract can yield good visual outcomes if posterior
segment is not involved and if post-operative complications
are managed efficiently.

Published: November 2020

El proceso de crecimiento del ser humano es complejo y variable, a lo largo de su vida se enfrenta a diferentes escenarios y aspectos que la sociedad impone como parte del desarrollo “normal” de todo individuo que culminan en la formación de una familia y la procreación de nuevos seres humanos para completar el entornos familiar idealizado. Sin embargo, la sociedad ha evolucionado y se ha vuelto más compleja por toda la información, el desarrollo y la tecnología, que a la vez que genera progreso.   Lo anterior crea confusión entre los miembros de la familia al desviar lo que por mucho tiempo se consideró prioridad para los padres como la unión, el desarrollo y fortalecimiento de valores familiares. Con la evolución de la sociedad, las prioridades se centran en el crecimiento profesional de los padres sin prever las necesidades básicas de sus hijos, en la mayoría de los casos, en que la participación económica de la madre se ha hecho cada vez más importante, y a la vez, no se ha planeado la evolución entre los tres conceptos básicos: Familia-Valores y Estabilidad Moral. Cuando en una familia no hay participación activa de los padres en la educación de los hijos, se crea un vacío de soledad y de sentido de ausencia, lo cual ha provocando un incremento del síndrome llamado “Depresión infantil”, que va en ascenso desde hace 10 años a la fecha. Los síntomas que se manifiestan son la actitud de ausencia, retraimiento e irritabilidad en los niños, lo cual marca su desarrollo y el de los padres. El alto índice de crecimiento de este síndrome está creando un  futuro incierto para: padres e hijos al no saber el tipo de traumas, conflictos emocionales y/o los trastornos de identidad que desarrollaran  los hijos y a los que se enfrentarán los padres al mismo tiempo; la sociedad al ser incierto el tipo de familias que se establecerán en el futuro; y los individuos afectados psicológicamente que no puedan expresar o recibir muestras de afecto o que al no haber recibido afecto, no puedan sentirlo y desarrollarse como un individuo dentro de la sociedad. Es responsabilidad de nosotros como padres y como miembros de una sociedad el ayudar a que este síndrome depresivo disminuya y a que podamos formar jóvenes libres en de mente y en de espíritu, jóvenes que puedan darnos un México mejor y que puedan librarse de trastornos emocionales que los lleven formar familias disfuncionales, y seguir con este síndrome en crecimiento. El presente trabajo identifico las principales características que refleja un niño con este síndrome, así como, la manera en que se puede atacar estimulando el crecimiento familiar y visualizar el impacto que se genera con técnicas básicas y elementales.

Performance of HIPERLAN/2 for 16QAM, with ¾ code rate with and without Rapp’s model
Authors: Bondre Miss. Kiran , Rathkanthiwar Mrs. Shubhangi
Published: November 2020

HIPERLAN/2 performance analysis via a MATLAB/Simulink simulation is present. This paper shows the results of simulations performed on a MATLAB/Simulink model HIPERLAN/2 system with and without a nonlinear power amplifier for AWGN channel. In the following analysis, an additive white Gaussian (AWGN) transmission channel is assumed since attention is focused on the effects on the nonlinearity. The power amplifier model used here is the Rapp’s Solid State Power Amplifier (SSPA) model. Here we showed that HIPERLAN/2 is much more sensitive to power amplifier nonlinearities. The paper shows that the received constellation points are considerably distorted after passing through the amplifier. The BER plot is more degraded when the transmitted signal passes through the amplifier than the plot when it does not pass through the amplifier.
Geographic Adaptive Fidelity and Geographic Energy Aware Routing in Ad Hoc Routing
Authors: Roychowdhury Sinchan , Patra Chiranjib
Published: November 2020

Location based routing protocols are the kinds of routing protocols, which use of nodes’ location information, instead of links’ information for routing. They are also known as position based routing. In position based routing protocols, it is supposed that the packet source node has position information of itself and its neighbors and packet destination node. In recent years, many location based routing protocols have been developed for ad hoc and sensor networks. In this paper we shall present the concept of location-based routing protocol, its advantages and disadvantages. We shall also look into two popular location-based protocols: Geographic Adaptive Fidelity (GAF) and Geographic and Energy Aware Routing (GEAR).
Distributed Computing for Ubiquitous Systems
Authors: Mani Mona
Published: November 2020

Distributed computing provides a strong foundation on top of which a powerful ubiquitous system can be realized. However, distributed computing is not solely sufficient for the ubiquitous systems –a completely new era of computer world which is not based on the conventional mainframes or PCs but on the virtually intelligent silent objects/devices used for dayto- day human activities. This article de scribes basics of ubiquitous systems at introductory level and discusses developing a ubiquitous system as an extension to DIICS (Distributed Intelligent Instrument Control System) – a temperature monitor and control system developed by t he author. Moreover, it also discusses significant role of Tini InterNet Interface - a technology used in DIICS, for embedded device support in ubiquitous systems. It also discusses how distributed system fundamentals best fits for ubiquitous systems. Furthermore, it discusses various distributed system goals and specifies how these goals can contribute to ubiquitous systems solely or partially. It also specifies respective changes, and demand for new or adapted architecture/platform, to accommodate it for an efficient ubiquitous system. Towards the end it describes Remote Process Call (RPC) and Event Notification model, two powerful distributed system techniques.
Performance analysis of Dynamic MANET Ondemand (DYMO) Routing protocol
Authors: Bisoyi Sukant Kishoro , Sahu Sarita
Published: November 2020

Routing in a MANET is challenging because of the dynamic topology and the lack of an existing fixed infrastructure. In such a scenario a mobile host can act as both a host and a router forwarding packets for other mobile nodes in the network. Routing protocols used in mobile ad hoc networks (MANET) must adapt to frequent or continual changes of topology, while simultaneously limiting the impact of tracking these changes on wireless resources. The DYMO protocol intended for the use by mobile nodes in wireless multihop ad hoc networks. It can adapt to the changing network topology and determine unicast routes between nodes within the network. This paper presents a comprehensive summarization and a comparative study of the Dynamic MANET On-demand (DYMO) protocol for MANET and simulation analysis of existing protocols DSR and AODV and comparison among them under varying number of nodes. Comparative study shows that DYMO is only a good choice if the nodes are mobile and wireless multihop. We have compared the performance of DSR and AODV with DYMO protocol by taking some performance metrics. Result shows that DYMO simulation provides better performance than DSR when compared in a given network topology with respect to throughput, packet loss, delay, packet delivery ratio, normalized routing load.

Published: November 2020

EU-Project FUTON Radio-over-Fiber (RoF) infrastructure proposes high transmission rates at small antenna costs, implying competitive CAPEX for next generation networks. But to be cost-efficient, it needs to employ new network architectures and intelligent technology solutions for decreasing network operational costs. The RoF Network Manager manages the network equipment on the optical front haul between the Central Unit (CU) and all Remote Antenna Units (RAU)s connected by it, as well as the communication links, while enabling end-to-end service problem resolution and service quality management by the FUTON Middleware. Although a significant amount of prior research work can be found in the literature related to RoF, there is still significant lack of technologies concerning RoF networks management. RoF Manager and its sub-systems target to fill such gap, proposing a novel concept in the form of Channel Forwarding Table (CFT). RoF Manager follows an autonomous and generic network management framework, designed to be scalable in terms of adding new network elements (NEs). It targets multitechnology, multi-service and multi-vendor NEs in the network using Simple Network Management Protocol (SNMP). It can also provide alternative paths in case of failure. This work puts forward a new paradigm towards RoF management solution managing network performance, network faults, network security and configurations for convergent networks.
The Awareness Of ICT Implementation For Materials Management In Construction Projects
Authors: Kasim N. B. , Ern Peniel Ang Soon
Published: November 2020

Construction materials usually constitute a major portion of the total cost in a building construction project. Despite the potential benefit of ICT, convincing construction organisations to embrace its use and implementation has proved a difficult task. This research seeks to identify the implementation of ICT in construction materials management processes and to investigate on the acceptance of contractors for ICT transformation to the materials management in construction projects. In relation to that, current constraints that are found hindering the acceptance of ICT in materials management processes are also identified. A triangulation research approach which consists of standard derived questionnaires, semi structured interviews with class A contractors and review of previous research were conducted. The findings from this research reveal that the implementation of ICT in the materials management for construction projects in Malaysia is at early stage. Microsoft Excel Spreadsheet and handheld devices are found to be the common ICT tools adopted in the materials management processes. Meanwhile, there is only an average level of acceptance towards the transformation of ICT implementation in the construction materials management. The main barrier is found to be the cost involvement at the initial stage or overall implementation of ICT in the materials management processes. Finally, it can be concluded that there is a lack of awareness towards the ICT implementation of materials management in the construction projects.
Predictive Data Mining: Promising Future and Applications

Published: November 2020

Predictive analytics is the branch of data mining concerned with the prediction of future probabilities and trends. The central element of predictive analytics is the predictor, a variable that can be measured for an individual or other entity to predict future behavior. For example, an insurance company is likely to take into account potential driving safety predictors such as age, gender, and driving record when issuing car insurance policies. Multiple predictors are combined into a predictive model, which, when subjected to analysis, can be used to forecast future probabilities with an acceptable level of reliability. In predictive modeling, data is collected, a statistical model is formulated, predictions are made and the model is validated (or revised) as additional data becomes available. Predictive analytics are applied to many research areas, including meteorology, security, genetics, economics, and marketing. In this paper, we have done an extensive study on various predictive techniques with all its future directions and applications in various areas are being explained.

Inferring Online Relationships from User Characteristics
Authors: VONGSINGTHONG Suwimon , BOONKRONG Sirapat , UNGER Herwig
Published: November 2020

A new approach to understanding human online behavior in regard to psychological functioning is proposed through the developed user’s activity model incorporating the influences of social behavior, network, and content. Microscopic levels of user characteristics induced by personality traits were interpolated as interaction rules, whilst an unsupervised clustering algorithm was applied to penetrate the individual complexity. Temporal behavior of disparate users was mimicked, and streaming network data was generated and computationally analyzed. A comprehensive understanding of how individuality, friendship, and varying temperaments dramatically reshaped the networks was gained from insight synthesis of network properties characterized by small-world, scale-free, and centrality measures. Evidence illustrates that users with high extraversion possess high numbers of friends and spread massive information, while high conscientious and high intellect users are seriously discreet in accepting friends and often produce influential content. These results not only provide a wealth of challenges for product recommendation, network structure optimization, and design, but also are useful for the prediction of future network structural evolution.

Authors: CHUSRI Orranuch , DEOISRES Wannee , RIPER Marcia van
Published: November 2020

Purpose: To predicate the way in which families incorporate the work of managing a child with thalassemia within family life and its outcomes. Methods: A correlational design with a structural equation modeling (SEM) approach was used. A total of 309 parents of children with thalassemia from 4 tertiary care hospitals in Thailand completed our questionnaires. Results: Family life difficulties had a negative influence on the child’s health-related quality of life (HRQOL) (b = -2.23, p < 0.05) and family functioning (b = -0.27, p < 0.05), whereas the child’s daily life (b = 5.06, p < 0.05) and condition management ability (b = -1.86, p < 0.05) had a negative influence on the child’s HRQOL. In the final model, 3 variables including the child’s daily life, condition management ability, and family life difficulty could explain 33 % of variance in the child’s HRQOL (R2 = 0.33). This model showed that only family life difficulty could explain 2 % of variance of family functioning (R2 = 0.02). Conclusions: The study suggests that nurses should design interventions to support families in managing their child’s conditions in order to achieve a good child and family outcomes.

The purpose of this study was to develop a Medication Adherence Scale for Persons with Coronary Artery Disease (MAS-CAD) based on a nursing perspective. This study was guided by scale development procedures, which consisted of 7 steps: 1) clarifying and determining the concept, 2) generating an item pool, 3) determining the format for measurement, 4) reviewing the initial item pool by 7 professional experts, 5) conducting preliminary item pilot study with 30 Thais with CAD, 6) conducting field-testing for psychometric property testing among 457 Thais with CAD who attended heart clinics of 7 tertiary hospitals in Thailand, and 7) developing scoring and interpretation of the scale scores. Data were analyzed by using descriptive statistics, content validity index, Cronbach’s alpha coefficient, confirmatory factor analysis by LISREL, and Pearson product moment correlation. The results showed that the MAS-CAD is a self-report instrument, comprised of 5 rating Likert-scale categorical format, composed of 25 items covering 4 constructs; proper knowledge of prescribed medication (7 items), storing medication appropriately (3 items), self-regulating medication administration correctly and continuously (11 items), and participating in the medication treatment plan (4 items). Psychometric property testing demonstrated satisfactory internal consistency with Cronbach’s alpha coefficient of 0.81, and test-retest reliability was acceptable (r = .62, p < .01). Construct validity was supported by confirmatory factor analysis. In conclusion, the MAS-CAD is a reliable and valid instrument. Nurses can use this scale as a tool for assessing medication adherence for persons with CAD.

Alzheimer’s disease (AD) is a chronic neurological disease related to the decline in brain and nervous system functions. At present, inhibitions of cholinesterases (ChEs) including acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) to enhance neurotransmitters and retardation of b-amyloid formation through b-secretase (BACE1) inhibition are 2 hypotheses for AD prevention and treatment. Hence, this study aims to investigate inhibitory activities against ChEs of various tea varieties of Camellia sinensis and herbal teas. At this step, the screening methodology for ChEs inhibitory activities in various tea varieties in order to provide a fast, inexpensive and convenient method for the detection of anti-cholinesterase activity was optimized. Then, selected tea with high ChEs was further examined regarding its BACE1 activity. As results, all tea samples displayed both anti-AChE and -BChE activities with the broad ranges of 6 - 85 % and 0 - 72 % inhibitory activities, respectively. Interestingly, C. sinensis teas exhibited higher ChEs inhibitory activities than herbal teas, in exception of Pandanus amaryllifolius (pandan) tea, which exhibited comparable inhibitory activities as C. sinensis teas. Pandan leaves were found to exhibit anti-BACE1 activity with 98 % inhibition. Besides, preliminary in vivo study showed that pandan leaves extract was able to rescue climbing defect observed in AD Drosophila melanogaster model, indicating the potential roles of pandan leaves in AD prevention.

Currently induction motors are widely used in industry due to strong construction, high efficiency, and cheap maintenance. Machine maintenance is needed to prolong the life of the induction motor. As studied, bearing faults may account for 42% -50% of all motor failures. In general it is due to manufacturing faults, lack of lubrication, and installation errors. Misalignment of motor is one of the installation errors. This paper is concerned to simulation of discrete wavelet transform for identifying misalignment in induction motor. Modelling of motor operation is introduced in this paper as normal operation and two variations of misalignment. For this task, haar and coiflet discrete wavelet transform in first level until fifth level is used to extract vibration signal of motor into high frequency of signal. Then, energy signal and other signal extraction gotten from high frequency signal is evaluated to analysis condition of motor. The results show that haar discrete wavelet transform at thirth level can identify normal motor  and misalignment motor conditions well

A radial distribution electrical network at a certain distance will have a large voltage loss due to conductive losses, especially at the endpoint. The tip voltage is determined by the distance of the distribution and the amount of load. The form of configuration also affects the amount of power loss and voltage loss. So that a good configuration is needed in order to obtain good efficiency. Reconfiguration of the distribution network is used to reset the network configuration form by opening and closing switches on the distribution network. Reconfiguration is expected to reduce power losses and improve distribution system reliability. Many feeders and buses on the network if calculated manually will be difficult and require a very long time. So it is necessary to solve problems using program assistance. In this case, use Particle Swarm Optimization (PSO). Particle Swarm Optimization (PSO) algorithm based on the behavior of a herd of insects, such as ants, termites, bees, or birds. BPSO is a development of the PSO algorithm designed to solve the optimization problem in a discrete combination, where the particle takes the value of binary vectors with length n and speed which is defined as the probability of bits to reach value 1. The results show a significant reduction in losses.

The use of motorbikes in indonesia is very suitable for the needs of the community because the price is relatively cheap, affordable for most people and the use of fuel and operational costs are quite economical. But sometimes vehicle owners forget not to pay attention to the condition of the motorbike because of their busy activities, so that the motorcycle breaks down on the engine parts. Based on these problems, a microcontroller-based system was made which gave a warning to the owners of voxion motorcycle vehicles. Microcontroller is a computer system that all or most of its elements are packaged in one ic chip, so it is often called a single chip microcomputer. Where this system prioritizes timeliness in oil changes, radiator water and indicators of damage in motorbikes. Submission of oil information using the buzzer. Radiators and indicators of damage to motorbikes are done via sms gateway to smart phones or android. For that we need data that is input into a system to be read by the tool. The tools used for monitoring motor conditions include speed sensors, arduino, at mega 8535, buzzer and sms gateway.
