Strategi Public Relations Dan Pencak Silat Tradisional
- Pencak silat is a facet of Indonesian culture. It has been emerging in Indonesia in recent years because of some issues. The primary issue is that traditional pencak silat is dying in its homeland, Indonesia. The number of people who learn traditional pencak silat is decreasing. Meanwhile, some countries have claimed that pencak silat originated from their lands. To prevent traditional pencak silat from vanishing, public relations efforts may be an option. How does public relations become helpful to put the public back to pencak silat? A literature study has been performed. In-depth interviews were organized to gain insights from an organization focused on traditional pencak silat. The study offered both online and offline PR approaches. The community may take the advantages of community relations to build engagement with the public. The spirit of pencak silat may also be shared through direct communication with audiences. Finally, all activities must be published on online media to strengthen online presence and to increase internet publicity.

Pengaruh Dimensi Karakteristik Komunitas Virtual terhadap Community Commitment dan Loyalitas Pengguna Kamera Dslr Merek Canon
This study aims to analyze the effect of dimensions of virtual community characteristics (i.e. interactivity, system quality, information reliabity, and reward for activity) on community commitment and consumers’ loyalty. The concepts of virtual community characteristics, community commitment and loyalty were taken from various resources. This research is quantitative and explanative in nature. Target respondents were the the users of Canon DSLR camera. Using a convenience sampling technique, a total of 100 responses were obtained. Based on multiple regression analysis, it was found that except system quality other dimensions of virtual community characteristics partially had positive effect on community commitment. In addition, it was also found that the dimensions of virtual community collectively had significant effect on community commitment and that community commitment had positive and significant effect on loyalty
Face Recognition System Based on Gabor Wavelets Transform, Principal Component Analysis and Support Vector Machine
Face Recognition is a well-known image analysis application in the branches of pattern recognition and computer vision. It utilizes the uniqueness of human facial characteristics for personnel identification and verification. For a long time, the recognition of facial expressions by using computer-based applications has been an active area of study to recognize face scheme through a face image database. It is used in a variety of essential fields of modern life such as security systems, criminal identification, video retrieval, passport and credit cards. In general, face recognition process can be summarized in three distinct steps: preprocessing, feature extraction, and classification. At first, histogram equalization and median filter are applied as preprocessing methods. Secondly, Gabor wavelets transform extracts the features of desirable facial characterized by, orientation selectivity, spatial locality, and spatial frequency to keep up the variations caused by the varying of facial expression and illumination. In addition to that, Principal Component Analysis methodology (PCA) is used in dimensionality reduction. At last, Support vector machine (SVM) is applied in classifying the feature of the image according to the classis of every mage. In order to test the approach used in this research, experiments were running on Yale database of 165 images from 15 individuals in MATLAB environment. The results obtained from the experiments confirmed the accuracy and robustness of the proposed system
Kinetic simulation of the sheath dynamics in the intermediate radio-frequency regime
The dynamics of temporally modulated plasma boundary sheaths is studied in
the intermediate radio frequency regime where the applied radio frequency and
the ion plasma frequency are comparable. Two kinetic simulation codes are
employed and their results are compared. The first code is a realization of the
well-known scheme, Particle-In-Cell with Monte Carlo collisions (PIC/MCC) and
simulates the entire discharge, a planar radio frequency capacitively coupled
plasma (RF-CCP) with an additional heating source. The second code is based on
the recently published scheme Ensemble-in-Spacetime (EST); it resolves only the
sheath and requires the time resolved voltage across and the ion flux into the
sheath as input. Ion inertia causes a temporal asymmetry (hysteresis) of the
sheath charge-voltage relation; also other ion transit time effects are found.
The two codes are in good agreement, both with respect to the spatial and
temporal dynamics of the sheath and with respect to the ion energy
distributions at the electrodes. It is concluded that the EST scheme may serve
as an efficient post-processor for fluid or global simulations and for
measurements: It can rapidly and accurately calculate ion distribution
functions even when no genuine kinetic information is available
Molecular docking studies on InhA, MabA and PanK enzymes from Mycobacterium tuberculosis of ellagic acid derivatives from Ludwigia adscendens and Trewia nudiflora
There is an urgent need to discover and develop new drugs to combat Mycobacterium tuberculosis, the causative agent of tuberculosis (TB) in humans. In recent years, there has been a renewed interest in the discovery of new anti-TB agents from natural sources. In the present investigation, molecular docking studies were carried out on two ellagic acid derivatives, namely pteleoellagic acid (1) isolated from Ludwigia adscendens, and 3,3′-di-O-methyl ellagic acid 4-O-α-rhamnopyranoside (2) isolated from Trewia nudiflora, to investigate their binding to two enzymes involved in M. tuberculosis cell wall biogenesis, namely 2-trans-enoyl-ACP reductase (InhA) and β-ketoacyl-ACP reductase (MabA), and to pantothenate kinase (PanK type I) involved in the biosynthesis of coenzyme A, essential for the growth of M. tuberculosis. Molecular docking experiments were performed using AutoDock Vina. The crystal structures of InhA, MabA and PanK were retrieved from the RCSB Protein Data Bank (PDB). Isonicotinic-acyl-NADH for InhA and MabA, and triazole inhibitory compound for PanK, were used as references. Pteleoellagic acid showed a high docking score, estimated binding free energy of −9.4 kcal/mol, for the MabA enzyme comparable to the reference compound isonicotinic-acyl-NADH.Knowledge on the molecular interactions of ellagic acid derivatives with essential M. tuberculosis targets could prove a useful tool for the design and development of future anti-TB drugs

Building textual OLAP cubes using real-time intelligent heterogeneous approach
This article describes how the ever-growing amount of data entails introducing innovative solutions in
or-der to capture, process, and store the information. OLAP has been considered a powerful analytical
technology that enables analysts to gain insight into data and project information from diversified
points of view. Thereupon, OLAP has been utilized in a broad spectrum of sensitive applications
in the industry. The technology has occupied its place at the forefront of the vibrant information
technology landscape of research in order to meet the evolving needs. One of these needs that has
enticed the researchers’ attention is providing real-time answers which suggests, in particular cases,
processing billions of records in few seconds or less. The limited processing capacities have arisen
as a major hurdle in the way of achieving such an aim. Although numerous improvements have been
suggested, few have considered the heterogeneous computing approach, whereby quantum leap in
terms of the response time has been achieved, albeit in most cases, only numerical data have been
utilized. In this article, the authors introduce a novel heterogeneous OLAP approach targets textual
OLAP cubes aggregation and can be utilized efficiently in OLAP-based pattern recognition problems.
In this context, the approach (a) exploits the GPU along with the CPU in order to process textual data.
(b) Stores the queries aggregations’ hash table in the global memory such that the higher aggregations
levels are being answered in a shorter time (c) Introduces an intelligent self-evaluating mechanism
(ISEM), that evaluates the resource efficiency on query-basis by deciding which resource (CPU or
GPU+CPU) is more reliable to process each query. The authors’ empirical results have shown the
achieved gain is up to thirty-two folds over the parallel CPU-based counterpart solution. Furthermore,
their approach has demonstrated that adopting aggregation-memory optimization significantly
improves the performance of high-level textual aggregations
Perceptions of young Jordanian adults to proposed anti-tobacco pictorial warning labels
<p>Abstract</p> <p>Background</p> <p>In commitment to the Framework Convention on Tobacco Control (FCTC), four new pictorial warnings are now being proposed for display on cigarette packages sold in Jordan. The aim of this study was to gauge the immediate perceptions of young Jordanian adults towards these new pictorials and compare these perceptions to those of the pictorial currently being used in the country.</p> <p>Methods</p> <p>A cross-sectional survey was conducted on a convenience sample of youth aged 17-26. The interviewer-administered survey gauged participants' perceptions of salience, fear elicitation, and gained information as well as participants' motivation to remain non-smokers or quit smoking after viewing each of the four proposed new pictorials as well as the current pictorial used in Jordan. Perceptions regarding each new pictorial were compared to the current pictorial.</p> <p>Results</p> <p>A total of 450 surveys were included in the analysis. The sample (mean age 20.9) was 51.6% female and 31.3% cigarette (regular or occasional) smokers. In smokers, only one proposed pictorial had significantly more smokers perceiving it as salient or adding to information when compared to the current pictorial. More smokers reported fear when observing the proposed pictorials compared with current pictorial, but overall proportions reporting fear were generally less than 50%. Furthermore, all new pictorials motivated significantly more smokers to consider quitting compared with the current pictorial; however, the overall proportion of smokers reporting motivation was < 25%. Among nonsmokers, significantly more respondents perceived the new pictorials as salient and fear-eliciting compared to the old pictorial, but there were no major differences in information added. Motivation to remain non-smokers was comparable between the old and new pictorials.</p> <p>Conclusion</p> <p>Given the variability of response across both smokers and nonsmokers, and across the three elements of perception (salience, added information, fear) for each pictorial, further testing of the pictorials in a more diverse sample of Jordanian young adults prior to launch is recommended.</p
International Veterinary Epilepsy Task Force recommendations for systematic sampling and processing of brains from epileptic dogs and cats
Traditionally, histological investigations of the epileptic brain are required to identify epileptogenic brain lesions, to evaluate the impact of seizure activity, to search for mechanisms of drug-resistance and to look for comorbidities. For many instances, however, neuropathological studies fail to add substantial data on patients with complete clinical work-up. This may be due to sparse training in epilepsy pathology and or due to lack of neuropathological guidelines for companion animals.
The protocols introduced herein shall facilitate systematic sampling and processing of epileptic brains and therefore increase the efficacy, reliability and reproducibility of morphological studies in animals suffering from seizures.
Brain dissection protocols of two neuropathological centres with research focus in epilepsy have been optimised with regards to their diagnostic yield and accuracy, their practicability and their feasibility concerning clinical research requirements.
The recommended guidelines allow for easy, standardised and ubiquitous collection of brain regions, relevant for seizure generation. Tissues harvested the prescribed way will increase the diagnostic efficacy and provide reliable material for scientific investigations
