Patrimonio cultural y turismo, una alternativa de desarrollo: caso Viotá, Cundinamarca
Authors: Martínez Herrera Óscar Javier
Published: September 2016

Este artículo presenta una descripción de la situación actual del patrimonio cultural del municipio de Viotá, realizado por el equipo interdisciplinario conformado por investigadores de los programas de Arquitectura, Economía y Administración Turística y Hotelera de la Universidad Piloto de Colombia. El objetivo del trabajo es identificar los bienes de interés cultural e histórico, los instrumentos e incentivos económicos, y las fuentes fiscales y de financiación que hacen posible la conservación del patrimonio cultural; dado que los recursos de financiación son limitados, el turismo es una fuente de ingreso alternativa para la conservación de estos elementos patrimoniales. La metodología es cualitativa y cuantitativa, y consistió en la aplicación de un cuestionario que se utilizó para la recolección de la información, que se estructuró en seis (6) módulos: identificación, acerca del patrimonio cultural, financiación, valor, observaciones y resultados de la encuesta. De acuerdo con los resultados obtenidos en la encuesta, se encontró que la población conoce parte de su patrimonio cultural, por ejemplo, haciendas cafeteras, caminos reales y petroglifos. Para el Ministerio de Cultura, el Ministerio de Comercio, Industria y Turismo y la unesco, es importante que la comunidad local, los turistas y los visitantes lo reconozcan y lo apropien con el fin de generar declaratoria en el nivel municipal.Los bienes culturales son parte del turismo porque generan experiencias en los turistas y visitantes. De acuerdo con la experiencia en trabajo de campo, el patrimonio cultural existente está deteriorado y en total abandono porque los propietarios no tienen los recursos para conservarlo, las vías que los conectan se encuentran en mal estado, no hay señalización y el costo de viaje es alto.
Uma reflexão sobre a qualificação na formação em turismo: relevancia da micro e pequena empresa para o destino turístico
Authors: Duarte Pimentel Thiago , Conceição de Paula Sara , Bifano de Oliveira Marcela Costa
Published: September 2016

Este artigo visa identificar os principais desafíos e tendências de qualificação e formação do turismólogo, bem como sua inserção profissional no contexto de um destino turístico (DT) majoritariamente formado por Micro e Pequenas Empresas (MPE’S). Com base na literatura especializada sobre MPE e sobre qualificação profissional em turismo, realizou-se uma pesquisa quali-quantitativa de cunho exploratório aplicado aos responsáveis pela contratação das organizações ligadas às Atividades Características do Turismo – ACTS. Após pesquisa bibliográfica e análise de dados secundários, a coleta foi baseada na técnica de amostragem particionada optando pelas organizações de maior representatividade do setor. Os resultados indicam, por um lado, que as mpes representam 92 % do trade turístico e, de outro, que é baixíssimo o índice de contração de pessoal qualificado em turismo, o que tende a impactar na capacidade e qualidade de elaboração de produtos turísticos. Ademais, identificou-se significativo desconhecimento das funções do turismólogo por parte das MPE’S e um despreparo deste em apresentar habilidades e competências aplicáveis a elas. Assim, conclui-se que há duplo desafio, estrutural e sistêmico, no sentido de qualificar as MPE’S, mas estas, por sua vez, precisam das habilidades e competências dos turismólogos, que todavia não estão plenamente desenvolvidas.

Does Knowledge Management Lead to Innovation? an Empirical Study on SMEs in Rwanda
Authors: Byukusenge Eugenie , C. Munene John , Orobia Laura
Published: September 2016

The purpose of this study was to investigate whether knowledge management under its three dimensions of knowledge acquisition, knowledge sharing and responsiveness to knowledge lead to innovation in Rwandan SMEs. The study adopted a cross-sectional survey design to collect data used to examine that relationship. The results revealed that only knowledge sharing was found positive and significant predictor of innovation. This implies that effective knowledge management through knowledge sharing may lead to innovation.This study used a cross-sectional research design combined with a quantitative research approach. Future researchers could employ a longitudinal method to investigate any possibility of variations in the results. Qualitative studies could equally be used to supplement the quantitative findings. Lastly, this study focused on manufacturing SMEs only. Future research might focus on other types of businesses. Owners-managers of SMEs may sustain their competitive position and survive longer when knowledge is effectively and efficiently shared in order to increase their innovation capability. The study generated empirical evidence on less studied phenomena in the SMEs sector. The evidence highlighted the powerful influence of knowledge sharing in predicting innovation in SMEs.

Published: September 2016

The population’s mobility in urban areas is a necessary variable in the modeling of risk scenarios caused by atmospheric contamination. The inclusion of this concept makes static models more dynamic while considering people within a city to be an entity with complex mobility processes. We propose a conceptual and methodological tool to make the representation of the social, economic and territorial components, as well as the patterns in the population´s mobility to delimitate risk areas for human health by exposure of contaminants. In the volatile organic compounds (VOC), benzene, ethylbenzene, toluene and xylene (BTEX) are amongst the most dominant substances in fugitive vapor emissions in gas stations (GS). In urban areas, the exposure to BTEX by residential proximity and proximity to other facilities, which cause intra-urban agglomeration, can impact and affect human health. This model seeks to facilitate the focalization, identification and prioritization of risk areas by BTEX environmental contamination. This article goes beyond de conceptual framework. It suggests methodological and instrumental aspects to be applied in other cities. The government agencies must consider these results when establishing rules, permissions and procedures to reduce environmental pollution for managing the risk in a complex urban environment.

Published: September 2016

               Electrical burn injuries are challenging burns that require multi disciplinary approach. It is a major cause of morbidity among burn victims and requires more number of interventions and hospital stay. Certain unique features that are to be kept in mind while treating electrical burn patients are the differences in fluid requirement, assessment of cardiac involvement, other associated injuries like head spine or bony injuries and renal damage. Aim of treatment of these victims is to prevent infection, to achieve skin cover to allow early mobilization, to optimize function and to minimize long term scarring. Special effective authentic care and proper rehabilitation can make the electrical burn victim a useful productive member of the family/society.

Enabling Efficient Drilling Operations Through Customized Data Driven Decision-Making
Authors: Atwal Harnam S. , Knight Sheldon J.
Published: September 2016

With recent downturn in Gas & Oil prices, there is an increased focus on finding ways to optimize the hydrocarbon recovery cycle. In this new economic reality, technology and analytics will have to be counted upon to deliver cost reduction solutions. This paper outlines one such solution applicable to unconventional shale drilling operations.

A two-pronged approach has been taken to customize decision making processes for the two phases – planning and execution. Traditionally, some form of offset well information is used in planning phase of a well to assess risk, allocate and acquire capital, and logistical planning. The variables used in these calculations are stochastic in nature and, as such, necessitate a stochastic simulation of the well. To run an accurate simulation, we assign a customized probability distribution function to each variable based on offset information. Offset information comes from a meticulously maintained database of local wells. Reliability of simulation accuracy depends heavily on quality of offset wells in the database. A high quality database will include wells drilled across many different geographical locations, by rigs with varying technical limitations and crew experience levels and by different drilling operators. In the execution phase, we use a similar combination of historical data and stochastic simulation process to predict the result of a change in drilling parameter before making the change. This is done by using a real-time decision making dashboard.

The paper shows some real world examples of inaccurate results obtained by traditional methods. We also run some stochastic simulations on our model and compare results with observed results. We show the model to have reliable predictive capabilities.

This paper provides a new tool which combines established statistical methods with good quality drilling data to improve predictive capabilities. The tool enables risk to be accurately built into drilling budgets. It also allows for a more reliable prediction of "unexpected" events such as stuck pipe, tool failures, mud losses, etc. By building in the effect of such events, variability of outcomes is dramatically reduced.
Pressure-Transient Characteristics of Fractured Horizontal Wells in Unconventional Shale Reservoirs with Complex Fracture Networks
Authors: Sun Jianlei , Schechter David
Published: September 2016

Unconventional shale reservoirs require massive and multistage hydraulically fractured horizontal wells in order to produce economically. Induced hydraulic fractures interacting with in-situ natural fractures results in complex or discrete fracture networks (DFN). Even though well testing characteristics in fractured reservoirs with vertical wells have been investigated extensively, there is indeed a lack of good understanding of well testing behaviors for hydraulically fractured horizontal wells in complex fracture networks.

First, three practical approaches are presented regarding how to generate complex fracture networks in the context of developing unconventional shale reservoirs with hydraulically fractured horizontal wells. Complex fracture networks can be generated 1) from stochastic algorithms that input fracture density, length and strike distributions, or 2) from the flowing-producing DFN (FP-DFN) area that is constrained by microseismic information, or 3) from digitization of realistic outcrop maps. Then, new unstructured fracture gridding and discretization techniques specially tailored for complex fracture networks are developed to handle nonuniform fracture apertures, extensively fracture clustering and nonorthogonal fracture intersections. Finally, numerical simulations of pressure build-up are performed in complex fracture networks that are generated from three proposed approaches using both synthetic and field examples. Flow regimes are identified and discussed based on pressure derivative plots.

Complex fracture networks show that the most representative characteristics are formation-fracture bilinear flow and formation linear flow regimes. The appearance of the bilinear flow regime during early period might be not clear due to the impact of wellbore storage effect for the fractal fracture generation approach. In addition, the microseismic-based approach reduces uncertainties of fracture characterization by using percentiles of FP-DFN areas. The pressure build-up responses clearly indicate that the higher the percentiles of FP-DFN areas, the lower the pressure difference and derivative curves. The fracture mineralization affects pressure build-up responses significantly. The decrease in nonuniform fracture apertures cause pressure diagnostic plots shift upward. The effect of boundary in the outcrop-based complex fracture network shows an early deviation from the formation linear flow regime. No classic dual porosity behavior is observed in all cases to quantify related parameters.

Three practical techniques are proposed to generate complex fracture networks. Pressure transient characteristics are identified and summarized. The open research areas are discussed and highlighted. This work helps us better understand pressure transient behavior of complex fracture networks and after-closure analysis of fracturing calibration test.
Revealing Patterns within the Drilling Reports Using Text Mining Techniques for Efficient Knowledge Management
Authors: Arumugam Sethupathi , Gupta Sanjay , Patra Biswaranjan , Rajan Shebi , Agarwal Satyam
Published: September 2016

In the current market conditions, foreseeing drilling risks and mitigating all the surprises beforehand will greatly reduce development costs. Rig personnel use the risk and message object in WITSML schema and daily drilling reports to capture rig activity, findings, unfavorable events, 24 hours well summary, etc. All the information from these objects are not extracted and effectively utilized in well planning exercise. This paper focuses on a collaborative approach of using text mining and knowledge management practices to mine unfavorable events and best practices from daily drilling reports and integrating them with subsurface information management system for maintaining risk inventory and Geospatial analysis.

The proposed approach applies Information retrieval, Extraction, Clustering, Pattern Identification and Knowledge Management on daily drilling reports from offset wells to identify any data that might be relevant to drilling anomalies and best practices. Text mining converts unstructured information within the reports to structured data that can be then stored within existing subsurface data management systems. The results of text mining can be integrated with Geospatial techniques to perform risk assessment by leveraging spatially distributed large datasets from offset wells.

This collaborative approach improves extracting and sharing of the risks and best practices among experts across the globe and alerting users of upcoming risks. This approach also enables building an effective risk inventory that can be reused for future well planning purposes. Using this approach, risk assessment can be executed for every rig activity, user defined depth range, hole section / size and upcoming formation markers. The results from text mining approach can also be visualized on advanced User Interfaces providing a bird's eye view of well operations.

This approach streamlines the evaluation of risks in the planning stage of the well and enables effective collaboration between the drilling, geological and geophysical teams during execution. It also improves risk management and knowledge management practices. With the proper training, a well-defined drilling process, sufficient data and tools for interpretation; drilling a well should become a routine process.
Impact of Completion Parameters on Marcellus Shale Production
Authors: Filchock J. J. , Aminian K. , Ameri S.
Published: September 2016

The Marcellus Shale is a prolific source of natural gas and is located in much of the Appalachian Basin, The combination of horizontal drilling and multistage hydraulic fracturing have proven extremely successful in achieving commercial production from this ultra-low permeability formation. Even though advances in technology have unlocked considerable gas reserves, the emergence of unconventional shale formations as targets for exploration and development have created new challenges for resource development. These challenges arise because the impact many reservoir and fracture parameters have on the effectiveness of the stimulation treatments to increase reserves and improve production efficiency is not well established.

The focus of this study is to identify what effect fracture half-length and well spacing have on the maximization of gas production and gas recovery efficiency from Marcellus Shale horizontal wells. A commercial reservoir simulator was used to develop a base model for the Marcellus Shale formation. These simulations models were constructed using information from the Marcellus Shale Energy and Environment Laboratory (MSEEL). MSEEL is a research collaboration between West Virginia University, Ohio State University, The National Energy Technology Laboratory, and Northeast Natural Energy. MSEEL is a long-term laboratory and field study that will assess the hydrocarbon production potential and the environmental and economic impacts of drilling and producing wells in the Marcellus Shale. The base model incorporated many of the complex reservoir characteristics that are associated with the Marcellus Shale. They include a horizontal wellbore, multi-stage fracture treatment, adsorbed gas, and in situ rock properties. Reservoir properties, such as porosity, permeability, natural fracture spacing, etc., were determine using history matching. The available data from two original horizontal Marcellus Shale gas wells at MSEEL were utilized for history matching the daily and cumulative gas production. The impact of completion parameters on gas recovery was investigated using history-matched models to evaluate the impact that fracture half-length and well spacing have on production. The predicted optimized production will be presented and compared to the baseline production results, and be presented in the paper.
Numerical Simulation of Stochastically-Generated Complex Fracture Networks by Utilizing Core and Microseismic Data for Hydraulically Fractured Horizontal Wells in Unconventional Reservoirs– A Field Case Study
Authors: Sun Jianlei , Niu Geng , Schechter David
Published: September 2016

Unconventional reservoirs require hydraulically fractured horizontal wells in order to produce reservoir fluids economically. Induced hydraulic fractures interacting with pre-existing natural fractures results in complex fracture networks (CFNs). Even though hydraulic fracture propagation has been investigated extensively, there is indeed a lack of good understanding of characterization approaches for pre-existing natural fractures. This work presents a practical CFN generation approach by incorporating stochastic algorithms, core, and microseismic data.

Based on analysis of geological structures and core observation, natural fracture density, length, and strike distributions can be obtained. Fracture length follows a power law distribution constrained by minimum, maximum and cutoff lengths as well as a distribution exponent. Fracture strike follows a Fisher distribution. Then, microseismic event locations are used to constrain fracture centers of stochastically generated natural fractures. Moreover, a fast proxy model is developed for hydraulic fracture propagation, which honors both the total mass volume of the pumped proppants, and the pre-defined reference lengths. Finally, a field case study is used to demonstrate how to apply the proposed fracture generation and simulation workflow to model hydraulically fractured horizontal wells.

The proposed workflow implemented stochastic algorithms with the capabilities to incorporate as much information as possible such as core analysis and microseismic information, and to evaluate uncertainties due to pre-existing natural fractures. With the assumption that microseismic event locations are reactivation of pre-existing natural fractures, the perturbed event locations constrained the locations of the natural fracture centers, resulting in a better description of microseismic-derived stimulated reservoir volume. The simplified hydraulic fracture propagation scheme was able to efficiently estimate the resulting complex fracture networks, and to accurately honor the material balance during fracturing treatment. Sensitivity analysis showed that fracture permeability, matrix porosity, and matrix permeability of the CFNs affect well production performance, significantly.

This paper discusses how to utilize available data resources to generate representative CFNs for hydraulically fractured horizontal wells. The process of data preparation for each step of the workflow is discussed in details to facilitate engineers to solve practical problems with the developed methodology.
Using Dielectric Dispersion Logging to Calculate the Parameters of Archie's Law
Authors: Kouchmeshky Babak , Khokhar Rashid
Published: September 2016

Dielectric logging is used in oil and gas exploration for estimating the hydrocarbon content of the reservoir and rock texture. This information is essential for making decisions on development and production of reservoirs. This paper looks at using dielectric dispersive behavior of formation and how it can be related to widely used parameters of Archie's law in petro-physics.

In dielectric logging, the electromagnetic properties, permittivity and conductivity of the formation are obtained over a frequency range. These properties exhibit a variation with respect to frequency, which is called dispersion. The dispersive behavior of formation as a whole is different from that of its constituents; water, oil and dry rock. This dispersive data can be used to obtain various petrophysical properties like water saturation, water resistivity and rock texture. Alternatively, Archie's law is widely used to relate the resistivity of formation to the resistivity of water, porosity and water saturation. The so-called Archie parameters, cementation and saturation constants, are widely used in petrophysics.

This paper discusses a novel approach that uses the dielectric dispersive behavior of a formation to provide a link to parameters of Archie's law. There exist many mixing laws that predict the dielectric dispersive behavior of a rock as a mixture of water, oil and dry rock. The proposed approach can be applied to any mixing law to provide parameters of Archie's law.

Detailed derivation of the Archie's parameters from known dispersive laws is provided through examples. The method is applied to published data on dispersive behavior of sample rocks and its prediction of Archie's parameters is compared with the values obtained from experiment. The proposed method is capable of relating textural parameters of rock used in mixing laws to Archie's parameters.

Con el objetivo de establecer la cifra de corte de leucocitos y edad con implicación pronostica en adultos con leucemia linfoblástica aguda (LLA), se efectuó un estudio observacional, descriptivo y analítico anidado en la cohorte retrospectiva de pacientes con LLA tratados mediante el protocolo institucional HGMLAL07 durante 2007-2014. Se estudiaron 255 pacientes, el 52.9% (n=135) correspondieron al género femenino y 47.1% (n=120) al género masculino. La media de edad fue de 31 (16-80) años. La supervivencia libre de la enfermedad (SLE) disminuyó en ambos géneros a partir de los 20 años (p=0.001). La media de leucocitos fue 56.1 x 109/L (0.1-850 x 109/L). La SLE disminuyó significativamente a partir de una cifra igual o mayor de 20 x 109/L (p<0.05). Con esto se puede concluir que emplear puntos de corte para leucocitos y edad obtenidos en poblaciones distintas pudiera condicionar una mala clasificación pronostica y un consiguiente tratamiento subóptimo.

Estudos em Gestão Internacional indicam que a distância psicológica impacta o desempenho organizacional, afetando também a questão da identidade organizacional em empresas em processo de internacionalização. Neste sentido, a partir de uma abordagem qualitativa e interpretativista, o presente estudo teórico-empírico teve por objetivo problematizar o fenômeno ainda pouco explorado da distância psicológica a partir da visão dos empregados estrangeiros de uma organização transnacional brasileira do setor de energia. A pesquisa empírica com empregados estrangeiros foi efetuada na Argentina, Colômbia e Venezuela. Os resultados ressaltaram que os fatores ambientais (formação de blocos comerciais, regiões e imigração e contatos fronteiriços) não se aplicaram ao nosso objeto de pesquisa, pois, embora estes países possuam fortes processos migratórios com o país de origem da empresa internacionalizada (no caso, o Brasil), ainda assim, existe uma considerável distância psicológica entre os empregados desses países com a sua matriz.

Introduction. Hemophagocytic lymphohistiocytosis (HLH) is a rare, potentially life-threatening, hyperinflammatory syndrome caused by severe hypercytokinemia due to a highly stimulated, but ineffective immune response. Case report. We reported a 19-year-old woman presenting with fever, muscle and joint pain and sore throat. After diagnostic procedures we made the diagnosis of hemophagocytic lymphohistiocytosis (7 of 8 HLH-2004 diagnostic criteria) caused by Ebstein-Barr viral infection and trigerred by the intense physical activity. Genetic analysis showed three different sequence changes in Munc-18-2, two splice acceptor side mutations/changes affecting exon 10 (c.795?4 C > T) and exon 15 (c.1247?10 C > T) and a missense mutation c.1375 C > T; p.Arg 459 Trp. All mutations were in heterozygous state and their significance in pathogensis of HLH is not clear. After treatment with corticosteroids and cyclosporin A complete clinical remission was achieved. Conclusion. The presented case history suggests the possibility that mutations of undetermined clinical significance in a gene associated with primary HLH may underlie some cases of secondary HLH, probably by causing a partial, rather than total or subtotal, impairment of encoded protein function. Our case also suggests that strenuous physical activity (in apparent synergy with viral infection) can trigger HLH.

Published: September 2016

Background/Aim. The longevity of a dental restoration may be predicted to some degree by its adhesive ability, and this, in turn, can be measured by bond strength testing between restorative materials and tooth structure. The aim of this study was to test an innovative joggle lap shearing jig that integrates the tooth and the entire biomechanical unit into testing, to compare the shear bond strengths of Class I occlusal composite restorations in deep cavity preparations lined with Dycal, Dycal LC, conventional glass ionomer or resin-modified glass ionomer. The mode of failure (adhesive, cohesive, mixed) after debonding was determined by stereomicroscopy. Methods. A total of 150 standardized occlusal cavities were prepared and divided into five groups. The group I cavities (n = 30) were coated with adhesive (ExciTE?F) and filled directly with composite (TetricEvoCeram). The group II and III cavities were lined with Dycal (n = 30) or Dycal LC (n = 30) before placing composite. The groups IV and V specimens were based with Fuji IX (n = 30) or Fuji II LC (n = 30). Shear bond strengths were determined with a universal testing machine and fractured bonding sites were analyzed under stereomicroscope. The mean bond strengths were analyzed using one-way ANOVA test (p < 0.05) and the means between the groups were analyzed with Student?s t-test. Results. The shear bond strength (MPa) of composite restorations in cavities without base (23.91 ? 4.54) was higher than cavities lined with Fuji II LC (17.45 ? 2.74), Fuji IX (8.76 ? 2.57), Dycal LC (13.07 ? 1.84) or Dycal (6.12 ? 1.28). The results using the jogged lap shearing jig were consistent with the literature. Conclusion. The shear bond strength of occlusal composite restorations in deep cavities without liners was greater than cavities lined with Fuji II LC > Fuji IX > Dycal LC > Dycal.

Authors: Radoicic Dragan , Dasic Zarko , Mitkovic Milorad , Starcevic Srdjan
Published: September 2016

Background/Aim. Total hip arthroplasty (THA) is one of the most widely accepted operative methods for femoral neck fracture (FNF) in elderly. However, the data on the early THA for FNF are very limited. The aim of this study to determine if there were differences in postoperative complications and functional outcomes between an urgent and delayed THA following FNF. Methods. This prospective study included a total of 244 patients who had THA following FNF from January 2010 to January 2013. In the first group 41 FNF patients were treated with THA within less than 12 hours of admission. A total of 203 FNF patients were operated in delayed settings, of whom 162 required prolonged preoperative processing and comorbidities correction. The group II consisted of 41 FNF patients who were fit for the early surgery at admission, but the operation was delayed due to institution related reasons. Main outcome measurements included mortality, functional outcome assessement, cardiological and pulmonary complications, pressure ulcers, dislocations, infections, length of hospitalization and revisions. Results. There were no differences in terms of age, gender, type of implants, neither in mortality, nor complications. There were differences in hospital length of stay [t (51.72) = -10.25, p < 0.001)]. The patients operated within less than 12 hours of admission, had significantly better scores at all three time points of functional outcome assessment: at discharge t (80) = 2.556, p < 0.012; one month t (80) = 4.731, p < 0.001; three months t (80) = 5.908, p < 0.001. Conclusion. THA for FNF as an urgent procedure is not a widely accepted concept. Our findings indicate that the early operative treatment, does not worsen clinical outcomes, and our results give an advantage to the policy of the early THA for FNF.

Published: September 2016

Background/Aim. Prostate delineation, pre-planning and catheter implantation procedures, in high-dose rate brachytherapy (HDR-BT), are commonly based on the prostate manually segmented transrectal ultrasound (TRUS) images. The aim of this study was to quantitatively analyze the consistency of prostate capsule delineation, done by a single therapist, prior to each HDR-BT fraction and the changes in the shape of the prostate capsule during HDR-BT, using two dimensional (2D) TRUS axial image. Methods. A group of 16 patients were treated at the Medical System Belgrade Brachytherapy Department with definitive HDRBT. The total applied median dose of 52 Gy was divided into four individual fractions, each fraction being delivered 2? 3 weeks apart. Real time prostate axial visualization and the manual segmentation prior to each fraction were performed using B-K Medical ultrasound. Quantitative analyses, analysis of an area and shape were applied on 2D-TRUS axial images of the prostate. Area analyses were used to calculate the average value of the cross-sectional area of the prostate image. The parameters of the prostate shape, the fractal dimension and the circularity ratio of the prostate capsule contour were estimated at the maximum axial cross section of the prostate image. Results. The sample group consisted of four phases, each phase being performed prior to the first, second, third and fourth HDR-BT fraction, respectively. Statistical analysis showed that during HDR-BT fractions there were no significant differences in the average value of area, as well as in the maximum shape of prostate capsule. Conclusions. Quantitative analysis of TRUS axial prostate segmented images shows a successful capsule delineation in the series of manually segmented TRUS images, and the prostate maximum shape remaining unchanged during HDR-BT fractions.

Published: September 2016

Background/Aim. Bronchial asthma is a disease that is characterized by the variability of the clinical picture, physical and functional status and the existence of bronchial hypersensitivity and hyperreactivity with varying degrees. Bronchial responsiveness and sensitivity are tested in patients with clinically suspected existence of asthma and normal spirometry test. The aim of the study was to analyze the patients with atopic asthma and study test results of skin sensitization to inhaled allergens, nonspecific bronchial hyperreactivity and specific hyperreactivity estimated by bronchial provocation tests with inhalant allergens. Methods. The prospective study at the Pulmonology Clinic of the Military Medical Academy in Belgrade Serbia, during 2014, included 70 male subjects aged 18?30 years, who had perennial asthma symptoms. All subjects were nonsmokers, with normal spirometry findings, with normal radiological chest findings and with no symptoms of respiratory infection over the past two months. All respondents were tested with skin prick tests with inhalant allergens and nonspecific bronchial provocation test with histamine. On the basis of histamine test, subjects were divided into two groups: the group I, in which there was a slight degree of hypersensitivity [provocation concentration of histamine causing a 20% fall in forced expiratory volume ? PC20 = 6.09 ? 1.1 mg/mL], and the group II with negative histamine test (PC20 = 14.58 ? 6.34 mg/mL). Specific bronchial provocation test was performed in all patients, and the selection of the allergens was carried out based on the results of testing of skin hypersensitivity. Results. Results of skin sensitization show the highest incidence of mites Dermatophagoides pterronissinus (83.3% group I and 85.0% group II) followed by grass pollen (53.3% group I and 52.0% group II), and house dust (33.3% group I and 50.0% group II). There were no statistically significant differences in allergens between groups (p > 0.05). In both groups, spirometry findings were within normal values [forced vital capacity ? FVC and forced expiratory volume 1 ? FEV1 > 80% predictive value], but statistically significant difference was found in FEV1 between groups (p < 0.05). Specific bronchial provocation tests with solutions of inhaled allergens in both groups caused a significant decline in FEV1 (? 20%) in all patients individually. No statistically significant differences were found neither between groups, nor between individual allergens (average decline in FEV1: Group I 32.9 ? 2.4% and group II 31.5 ? 2.2%). Conclusion. There is no relationship between the degree of specific and non-specific bronchial hyperreactivity in patients with allergic asthma.

Background/Aim. Preservation of an adequate posterior tibial slope (PTS) during total knee arthroplasty is crucial for the biomechanical stability and function of the knee joint. Studies that investigated anatomical features of the tibial plateau found significant gender and inter-population differences in all components of the PTS. The aim of this study was to establish reference values of PTS in Serbian population and to explore if there is any difference in the tibial plateau inclination between genders. Methods. We retrospectively reviewed 161 magnetic resonance images (MRIs) of the knee of adult patients examined in Medical Military Academy in Belgrade, Serbia, in a period from November 2011 to September 2014. Measurements of PTS components: medial tibial slope (MTS), lateral tibial slope (LTS), and coronal tibial slope (CTS) were performed through several steps, according to the suggestions in the recent literature. Obtained values for each tibial slope were compared between gender subgroups using appropriate statistical tests. Results. Mean values of each component of the posterior tibial slope for male vs. female subgroups were as follows: MTS 3.7? ? 2.8? vs. 5.1? ? 2.9?, LTS 4.2? ? 2.8? vs. 4.3? ? 2.7?, and CTS 3.9? ? 2.4? vs. 3.3? ? 1.9? respectively. The medial tibial slope was significantly higher in females than in males (p = 0.005). The mean value of the coronal tibial slope was greater in males without statistically significant difference (p = 0.105). Conclusion. This study demonstrated significant difference in MTS of the tibial plateau between males and females, being higher in the female subgroup.
Extremely tortuous coronary arteries - when optical coherence tomography and fractional flow reserve did not help us much

Introduction. Extreme coronary tortuosity may lead to flow alteration resulting in a reduction in coronary pressure distal to the tortuous segment, subsequently leading to ischemia. Therefore the detection of a true cause of ischemia, i.e. whether a fixed stenosis or tortuosity by itself is responsible for its creation, with non-invasive and invasive methods is a real challenge. Case report. We presented a case of a patient with a history of stable angina [Canadian Cardiovascular Society (CCS class II)], an abnormal stress test and coronary tortuosity without hemodynamically significant stenosis. Due to suspected linear lesion between the two bends in proximal segment of Right coronary artery (RCA) we performed optical coherence tomography (OCT), minimum lumen area (MLA)-13.19 mm2) and fractional flow reserve (FFR) RCA (0.94). We opted for conservative treatment for stable angina. Conclusion. When tortuosities are associated with atherosclerosis in coronary artery for determination of true cause of ischemia invasive methods can be used, such as OCT and FFR.

Development of an International Clinical Education Extracurricular Experience Through a Collaborative Partnership
Authors: Mandich MaryBeth , Erickson Mia , Nardella Beth
Published: September 2016

Background and Purpose

Participating in global health care through international clinical education may enhance the development of cultural competence and professionalism. Many logistical issues need to be resolved in the development of international clinical education experiences that meet program requirements. The purpose of this case report is to describe how a university developed such an experience for students by partnering with Amizade Global Service-Learning (Amizade), an organization that facilitates global learning experiences.

Case Description

Medical, nursing, and pharmacy students were already participating in a 4-week international health-related service learning rotation through Amizade. The preexisting relationship and contractual agreement with the university provided the necessary legal framework. Amizade staff assisted in finding a physical therapist qualified and willing to host a student. The academic coordinator for clinical education at the university and Amizade liaisons determined living arrangements, schedule, clinical settings, and patient population. The selected student had expressed interest and had met all clinical education placement requirements. The academic coordinator for clinical education had ongoing electronic communications with all parties.

Outcomes and Discussion

The student demonstrated predicted attributes of cultural competence and professionalism; through the partnership with Amizade, the student was exposed to several unique interprofessional experiences. The steps used by the university faculty in developing this interprofessional, international clinical education experience through a collaborative partnership may provide guidance for other institutions.
Media Coverage of Valentine’s Day: Is Media Biased in Covering the Festival?
Authors: Siddiqui Taha
Published: September 2016

Valentine’s Day celebration in India has been much debated and covered by the media in the last couple of years. In the year 2009, far right Hindu activist from Sri Ram Sena to Bajrang Dal were involved in beating up unmarried couples and blackening their faces, as mark of shame for celebrating Valentine’s Day. They claimed that the festival was a “western practice” and promotes “lust not love”. Following this other Anti- Valentine’s Day groups also expressed their views and this led to public debate about moral policing and Indian culture. However what is interesting to note is the fact how media covered. At one side media has played a big role in promoting it (for many reasons) and on the other hand it has also criticized it for cultural and religious concerns.This research tries to explore in depth how media covers the festival with commercialization, culture, religion and politics in the backdrop. The research studies 9 newspapers of in 3 different languages, namely English, Hindi and Urdu.  The study tries to find out whether media is biased in covering the festival or is it propagating an idea to its readers. The idea of taking 3 different languages is to draw a sharp comparison and contrast among the national and vernacular newspapers.In order to find it, both quantitative and qualitative methods have been applied to the articles. Content analysis and Textual analysis are the important methods used to find out the statistics and underlying meanings behind these articles.Int. J. Soc. Sc. Manage. Vol. 3, Issue-3: 171-187
Emotional Intelligence and Self-Efficacy as Determinants of Ethical Work Behaviour of Artisan in Maiduguri, Borno State Nigeria

Published: September 2016

This study investigated the role of emotional intelligence and self-efficacy on ethical work behavior of artisan in Maiduguri, capital of Borno State Northeast Nigeria. The study adopted behavioural theory of obedience as its main theoretical framework. Expos facto survey design was adopted for the study. Two hundred and eight-two (282) participants were selected accidentally for the study. Results revealed that artisans who reported with high emotional intelligence were significantly different in the level of ethical work behaviour compared to those who reported low level of emotional intelligence. Emotional intelligence does not significantly predict ethical work behavior of artisan and self-efficacy significantly predict ethical work behavior of artisans. However, it shows that emotional intelligence and self-efficacy jointly predict ethical work behavior of artisan. There was no any significant main and interaction effect of emotional intelligence and self-efficacy on ethical work behaviour among artisans in Maiduguri. Female artisans significantly reported higher scores on ethical work behaviour scale than male artisans. The study however recommended that management of the organization should send their employees (artisans) on sponsored training programme of the organisation which focused on enhancing their ethical work behavior.Int.
