Authors: Mery Luz Muñoz Yánez, Wilson E. Naranjo M. Oscar Armando Gavidia Albarracín, 
Published: August 2016

A partir del proyecto de investigación titulado “Evaluación del uso industrial de diatomitas, sector Tunja-Chivata”, con el apoyo de Colciencias y la Universidad Pedagógica y Tecnológica de Colombia, se efectuó el reconocimiento geológico en los municipios de Tunja, Chivatá y Siachoque,el cual comprende: el área de interés específico, mediante trabajo directo de campo; análisis de fotografías aéreas e identificación de las diferentes unidades geológicas aflorantes y un depósito piloto de Diatomeas. Se identificaron nuevas áreas con presencia del mineral de interés en un total de 13 depósitos denominados satélites en el área de investigación. A partir de la caracterización física y química se describen aspectos litológicos aflorantes. Del mismo modo, se denota el contexto geológico para cada uno de ellos. Entre los logros más significativos se destaca el reconocimiento de ocho depósitos hallados en el municipio de Siachoque, hasta ahora no mencionados, con características de gran interés para su beneficio y aprovechamiento. Sus aspectos físicos, químicos y accidentes topográficos señalan una factible continuidad entre los diferentes yacimientos aflorantes. Marcados por el nivel base del río Tocavita y Cormechoque, se observa allí una interrupción menor que se manifiesta debido a la erosión dentro del área del yacimiento, seguida de un depósito del cuaternario.

Published: August 2016

This article discusses the analysis of customer loyalty using three data mining methods: C4.5,Naive Bayes, and Nearest Neighbor Algorithms and real-world empirical data. The data contain ten attributes related to the customer loyalty and are obtained from a national multimedia company in Indonesia. The dataset contains 2269 records. The study also evaluates the effects of the size of the training data to the accuracy of the classification. The results suggest that C4.5 algorithm produces highest classification accuracy at the order of 81% followed by the methods of Naive Bayes 76% and Nearest Neighbor 55%. In addition, the numerical evaluation also suggests that the proportion of 80% is optimal for the training set.

Authors: Jonathan Claresta Janice , Tarigan Riswan 
Published: August 2016

Indonesia is a nation that ethnically and culturally unique and diverse. It has potentials to leverage the growth of its tourism sector. The sector has become important to boost not only regional and also nation- wide economic development. It can be growth further to a much larger scale by effectively utilising the pervasiveness of the information and communication technology (ICT). For example, ICT may facilitate the growth with e- tourism, which is an Internet-based marketing method. This work intends to understand the potential of using e-tourism and its effects on the development of the sector. Specifically, the study evaluates how the aspects of marketing, business, and e-tourism are affected by the use of ICT and how they affect the growth of the tourism industry. A multivariate regression model is constructed to assess the case quantitatively. The empirical model suggests that the e-tourism may contribute the growth of the tourism sector by about 40%.
Geometric Model for Human Body Orientation Classification
Authors: Ardiyanto Igi 
Published: August 2016

This paper proposes an approach for cal- culating and estimating human body orientation using geometric model. A novel framework integrating gradient shape and texture model of the human body orientation is proposed. The gradient is a natural way for describing the human shapes, while the texture explains the body characteristic. The framework is then combined with the random forest classifier to obtain a robust class differ- ence of the human body orientation. Experiments and comparison results are provided to show the advantages of our system over state-of-the-art. For both modeled and un-modeled gradient-texture features with random forest classifier, they achieve the highest accuracy on separating each human orientation class, respectively 56.9% and 67.3% for TUD-Stadtmitte dataset.

Published: August 2016

Information technology has affected various sectors including the education sector. In the sector, information technology has brought us long distance education, which relies heavily on the use of e-learning management system. In Indonesia, Bina Nusantara University is the first and foremost long distance education institution. The institution has been developing and using an e-learning management system for a number of years. This work intends to evaluate to which extent the system is able to enhance e-learning experiences. We adopted the DeLone and McLean’s Information System success model and empirically measured the relation between the aspects of system quality, information quality, service quality, user satisfaction, and net benefits. From a population of the size 311 students, we have collected 149 responses using questionnaires by randomly selecting the participating students. The responses were used to establish a multi-variate regression model where the relationships were established. The model suggested that information quality, system quality, and service quality had positive impacts on user satisfaction with the p-values of 0.014, 0.014, and 0.000 respectively. In addition, the study also found that user satisfaction was strongly and positively affected by the net benefits.

Published: August 2016

Currently, many company’s marketing strategies are limited only to face-to-face communication, telephone, facsimile, company portfolio, and product brochures. However, those marketing strategies are well- known to have limited impacts. Therefore, the presence of e-marketing as one of the marketing strategies would be appropriate to cover the weaknesses and to solve a number of the marketing problems. The purpose of this study is to discuss matters related to marketing, such as, proposing a marketing plan using website, expanding marketing segment, and introducing existing products for a chemical manufacturing company. The adopted research method is a descriptive method where the study is directly performed on the research object to acquire necessary data. The collected data are further analyzed using the Porter’s Five Force and SWOT analysis. Fi- nally, the work provides a number of recommendations for implementing e-marketing strategies to support the company business.

Published: August 2016

Background and objectives
Few studies have evaluated vascular access use after transition from peritoneal dialysis to hemodialysis. Our study characterizes vascular access use after switch to hemodialysis and its effect on patient mortality and evaluates whether a peritonitis event preceding the switch was associated with the timing of permanent vascular access placement and use.

Design, setting, participants, & measurements
The US Renal Data System data were used to evaluate the establishment of a permanent vascular access in 1165 incident Medicare–insured adult patients on dialysis who initiated peritoneal dialysis between July 1, 2010 and June 30, 2011 and switched to hemodialysis within 1 year.

Results
The proportions of patients using a hemodialysis catheter were 85% (744 of 879), 76% (513 of 671), and 51% (298 of 582) at 30, 90, and 180 days, respectively, after the switch from peritoneal dialysis to hemodialysis. Patients who switched from peritoneal dialysis to hemodialysis with a previous peritonitis episode were more likely to dialyze with a catheter at 30 days (90% [379 of 421] versus 80% [365 of 458]; P=0.03), 90 days (82% [275 of 334] versus 71% [238 of 337]; P=0.03), and 180 days (57% [166 of 289] versus 45% [132 of 293]; P=0.04) after the switch and less likely to dialyze with an arteriovenous fistula at 30 days (8% [32 of 421] versus 16% [73 of 458]; P=0.01), 90 days (13% [42 of 334] versus 23% [76 of 337]; P=0.03), and 180 days (31% [91 of 289] versus 43% [126 of 293]; P=0.04). Patients using a permanent vascular access 180 days after switching from peritoneal dialysis to hemodialysis had better adjusted survival during the ensuing year than those using a catheter (hazard ratio, 0.66; 95% confidence interval, 0.44 to 1.00; P=0.05).

Conclusions
Among patients who switch from peritoneal dialysis to hemodialysis, prior peritonitis is associated with a higher rate of persistent hemodialysis catheter use, which in turn, is associated with lower patient survival. Studies addressing vascular access planning and implementation are needed in this group of patients.
Finding Needles in a Haystack: Using Data Analytics to Improve Fraud Prediction
Authors: Perols Johan L. , Bowen Robert M. , Zimmermann Carsten , Samba Basamba 
Published: August 2016

ABSTRACT
Developing models to detect financial statement fraud involves challenges related to (1) the rarity of fraud observations, (2) the relative abundance of explanatory variables identified in the prior literature, and (3) the broad underlying definition of fraud. Following the emerging data analytics literature, we introduce and systematically evaluate three data analytics preprocessing methods to address these challenges. Results from evaluating actual cases of financial statement fraud suggest that two of these methods improve fraud prediction performance by approximately 10 percent relative to the best current techniques. Improved fraud prediction can result in meaningful benefits, such as improving the ability of the SEC to detect fraudulent filings and improving audit firms' client portfolio decisions.
Does Investors' Desire to Punish Misreporting Affect Their Litigation Decisions and Managers' and Investors' Welfare?
Authors: Brown Jason L. , Moser Donald V. 
Published: August 2016

ABSTRACT
Shareholder litigation is an important part of the regulation of securities markets that can influence corporate managers' reporting behavior. Prior research shows that conventional economic factors affect investors' litigation decisions. We use experimental markets to examine whether investors engage in costly litigation even without a direct financial incentive to do so and whether this affects managers' reporting decisions and managers' and investors' welfare. We find that investors frequently litigate when they can impose a financial penalty on managers for misreporting even though they cannot recover their legal fees or receive restitution for their losses. Moreover, this deters managers' shirking and misreporting and improves managers' and investors' welfare almost as effectively as when investors can recover their legal fees and receive restitution for their losses. Overall, our results indicate that, in addition to financial incentives, investors' desire to punish misreporting plays an important role in their litigation decisions, and that may yield substantial welfare benefits.

Abstract
OBJECTIVE To determine the efficacy of Bdellovibrio bacteriovorus 109J for the treatment of calves with experimentally induced infectious bovine keratoconjunctivitis (IBK).
ANIMALS 12 healthy dairy calves.
PROCEDURES For each calf, a grid keratotomy was performed on both eyes immediately before inoculation with Moraxella bovis hemolytic strain Epp63–300 (n = 11 calves) or nonhemolytic strain 12040577 (1 calf). For each calf inoculated with M bovis Epp63–300, the eyes were randomly assigned to receive an artificial tear solution with (treatment group) or without (control group) lyophilized B bacteriovorus 109J. Six doses of the assigned treatment (0.2 mL/eye, topically, q 48 h) were administered to each eye. On nontreatment days, eyes were assessed and corneal swab specimens and tear samples were collected for bacterial culture. Calves were euthanized 12 days after M bovis inoculation. The eyes were harvested for gross and histologic evaluation and bacterial culture.
RESULTS The calf inoculated with M bovis 12040577 did not develop corneal ulcers. Of the 22 eyes inoculated with M bovis Epp63–300, 18 developed corneal ulcers consistent with IBK within 48 hours after inoculation; 4 of those eyes developed secondary corneal ulcers that were not consistent with IBK. Corneal ulcer size and severity and the time required for ulcer healing did not differ between the treatment and control groups.
CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that B bacteriovorus 109J was not effective for the treatment of IBK; however, the experimental model used produced lesions that did not completely mimic naturally occurring IBK.

Abstract
OBJECTIVE To compare gene expression patterns of T cells in porcine colostrum and peripheral blood.
ANIMALS 10 multiparous sows.
PROCEDURES Cytotoxic and CD4-CD8 double-positive T cells were separated from porcine colostrum and peripheral blood. Total RNA was extracted. The cDNA prepared from RNA was amplified, labeled, fragmented, and competitively hybridized to DNA microarray slides. The DNA microarray data were validated by use of a real-time reverse-transcription PCR assay, and expression of the genes FOS, NFKBI, IFNG, CXCR6, CCR5, ITGB2, CCR7, and SELL was assessed. Finally, DNA microarray data were validated at the protein level by use of flow cytometry via expression of c-Fos and integrin β-2.
RESULTS Evaluation of gene expression profiles indicated that in contrast to results for peripheral blood, numerous cell-signaling pathways might be activated in colostrum. Profile analysis also revealed that FOS and NFKBI (genes of transcription factors) were involved in most cell-signaling pathways and that expression of these genes was significantly higher in colostral T cells than in peripheral blood T cells. Furthermore, CCR7 and SELL (genes of T-cell differentiation markers) in colostral T cells had expression patterns extremely similar to those found in effector or effector memory T cells.
CONCLUSIONS AND CLINICAL RELEVANCE All or most of the T cells in colostrum had an effector-like phenotype and thus were more activated than those in peripheral blood. This gene expression profile would enable T cells to migrate to mammary glands, be secreted in colostrum, and likely contribute to passive immunity provided by sows to newborn pigs.

Abstract
OBJECTIVE To characterize platelet-activating factor (PAF)–induced edema and erythema in the skin of dogs and compare those reactions with histamine-induced cutaneous reactions.
ANIMALS 6 healthy Beagles.
PROCEDURES Experiments were performed at ≥ 2-week intervals. Each dog received ID injections (5 μg/site) of PAF C16, PAF C18, lyso-PAF, and histamine. Edema (mean diameter) and erythema scores (none, mild, moderate, or severe) were assessed 30 minutes after the injections. Dogs received ID injections of PAF and histamine each with various concentrations of WEB 2086 (PAF receptor antagonist) or underwent ID testing with PAF and histamine before and 3 hours after oral administration of cetirizine hydrochloride or prednisolone (at 2 doses each).
RESULTS ID injections of PAF C16 and PAF C18, but not lyso-PAF, induced comparable levels of edema and erythema. The PAF-induced edema and erythema peaked at 30 minutes and lasted for 6 hours after the injection; histamine-induced edema and erythema peaked at 30 minutes and lasted for 3 hours after the injection. Edema sizes and erythema scores were significantly smaller and lower, respectively, for PAF than for histamine. The WEB 2086 inhibited PAF-induced but not histamine-induced edema and erythema. Cetirizine slightly, but significantly, repressed PAF-induced edema and erythema as well as histamine-induced cutaneous reactions. Prednisolone suppressed both PAF-induced and histamine-induced edema and erythema.
CONCLUSIONS AND CLINICAL RELEVANCE In canine skin, the duration of PAF-induced inflammation was longer than that of histamine-induced inflammation. The PAF- and histamine-induced cutaneous reactions were effectively suppressed by oral administration of prednisolone. The importance of PAF in dogs with anaphylaxis and allergic disorders warrants further investigation.

Pancytopenia following rituximab therapy in a patient with rheumatoid arthritis: Could filgrastim be a temporary solution?
Authors: Manappallil Robin George 
Published: August 2016

Rheumatoid arthritis is a chronic inflammatory disease affecting the peripheral joints and can also have extraarticular manifestations. The introduction of biological agents have opened new windows to the treatment of rheumatoid arthritis. Rituximab is a monoclonal antibody directed against CD20 cells, thereby reducing the inflammation. There have been reports of neutropenia, but pancytopenia is an uncommon incident. Filgrastim, a human granulocyte colony stimulating factor, can stimulate neutrophil production. The patient being described is a case of rheumatoid arthritis, who developed severe pancytopenia following rituximab therapy. She was given filgrastim injections, which temporarily normalized her leucopenia and neutropenia. This report emphasizes the possibility of developing pancytopenia following rituximab injection and the need of regular follow up of complete blood counts. In such cases, filgrastim may be a temporary solution. Also special consideration should be given to the increased risk of infections after taking rituximab.Asian Journal of Medical Sciences Vol.7(5) 2016 138-141
