Study on the Properties of SCLAC Using Infrared Thermography and Ultrasonic Pulse Velocity
Authors: Chen Tung-Tsan , Hung Ying-Chun 
Published: October 2018

AbstractA densified mixture design algorithm (DMDA) was employed to produce self-consolidating lightweight aggregate concrete (SCLAC). Lightweight aggregates with different particle densities were evaluated, and the batched water density and water-to-binder (w/b) ratio were varied. The results indicated that the properties of SCLAC mixed according to the DMDA were better than those according to the American Concrete Institute (ACI). Specifically, the slump and slump flow were greater than 250 mm and 500 mm, respectively. For instance, the strength of the material developed quicker; after 7 days of aging, the compressive strength of the specimen was 72 % of the strength obtained after 28 days. Under identical conditions, the compressive strength of SCLAC showed the best development when the w/b ratio was equal to 0.32 (45 MPa after 91 days). When the lightweight aggregate concrete was mixed according to the ACI mixture’s algorithm, the electrical resistivity of the SCLAC reached 53 KΩ-cm and improved to 40 KΩ-cm. The durability of material synthesized according to the DMDA was better than that of the traditional ACI mixture design. The degree of aggregate floating affected the location of the particles and the uniformity of concrete by approximately 20–40 %. Moreover, the results revealed that a low w/b ratio or mixing water density enhanced the development of the pulse ultrasonic velocity. The ability of aggregates with different specific gravities to transmit heat was determined by applying an infrared thermal method, and the results suggested that specimens with different particle densities (800 and 1,300 kg/m3) presented significant differences in temperature variations. Lastly, scanning electron microscopy showed that hydration continued as the age of the material increased, which increased the compressive strength and compactness. In conclusion, a concrete mix designed with DMDA has higher workability and reaches design strength faster.

Perfil profesional del dirigente deportivo regional: Valle del Cauca y Risaralda
Authors: Rodríguez Martha Sandino 
Published: October 2018

La dirigencia deportiva en Colombia presenta dos grandes problemas: las personas que son elegidas para los cargos públicos en los entes deportivos territoriales, cuentan con influencia y/o padrinazgo en el campo político; y en el sector privado (asociado), éstos dirigentes regularmente son ex deportistas o familiares de un deportista, sin contar con suficiente conocimiento sobre las funciones y habilidades en el sector. El segundo problema se refiere a la formación. Los actuales dirigentes deportivos no tienen una formación académica que les otorgue las competencias necesarias para desarrollar una adecuada gestión (o gestión de calidad), ni están formados académicamente en administración y gestión deportiva, conocimiento del sector y manejo de un segundo idioma. Normalmente sólo cumplen las 40 horas requeridas para ocupar cargos de dirección deportiva, según la Resolución 00547 del 2010 de Coldeportes. Si se apunta al logro de resultados trascendentes y al desarrollo del sector, un dirigente deportivo debe ser un gerente preparado para asumir con efectividad la gestión y administración de los productos y servicios deportivos. El presente estudio sobre el perfil profesional del Dirigente Deportivo Regional Valle del Cauca y Risaralda - va de la mano con la política pública del sector Plan Decenal del Deporte, la recreación, la actividad física y la educación física en Colombia para el desarrollo humano, la convivencia y la paz 2009-2019, cuyo primer lineamiento está direccionado al fortalecimiento de las organizaciones del sector y para ello se requiere de dirigentes competentes. Se trata de un estudio descriptivo, desarrollado por medio de encuesta aplicada a la población total de presidentes de las Ligas Deportivas de los dos departamentos, con el fin fundamental consiste en conocer su nivel de formación sobre administración y gestión deportiva y su experiencia en el sector en cargos de dirección.

Authors: Suhid Asmawati 
Published: October 2018

AbstractEducation is an important aspect in fulfilling the mission and human development agenda. Hence, Islam places great importance in education as was stated in the first verse revealed to the Prophet Muhammad (PBUH). In Malaysia, education is also a priority in the country’s development including Islamic education. The Islamic Education System in Malaysia is constantly evolving and changing in order to meet the needs and demands of the society. Parents and societies who are increasingly interested and realised the importance of Islamic education have created various forms and types of Islamic education. As an example, the emergence of Maahad Tahfiz, Ulul Albab programme, private Islamic Schools, Darul Quran and the J-QAF programme showed a very encouraging improvement. Attention is also given to the children of young prisoners and married teenagers in order they are not left behind in the mainstream education. Hence, this paper will discuss the development, strengthening and transformation of the Islamic education system in Malaysia besides highlighting some research findings that support this discussion. Abstrak Pendidikan merupakan aspek penting dalam memenuhi misi dan agenda pembangunan manusia. Oleh karena itu, Islam menekankan pentingnya pendidikan seperti Firman dalam ayat pertama yang diwahyukan kepada Nabi Muhammad (SAW). Di Malaysia, pendidikan juga menjadi prioritas dalam pembangunan negara termasuk pendidikan Islam. Sistem Pendidikan Islam di Malaysia terus berkembang dan berubah untuk memenuhi kebutuhan dan tuntutan masyarakat. Orang tua dan masyarakat yang semakin tertarik dan menyadari pentingnya pendidikan Islam telah menciptakan berbagai bentuk dan jenis pendidikan Islam. Sebagai contoh, munculnya Pesantren Tahfiz, Program Ulul Albab, Sekolah Islam swasta, Darul Quran dan program J-QAF menunjukkan peningkatan yang sangat menggembirakan. Perhatian juga diberikan kepada tahanan anak-anak dan remaja yang sudah menikah agar mereka tidak tertinggal dalam meraih pendidikan pada umumnya. Oleh karena itu, dalam artikel ini penulis akan membahas tiga topik utama; pengembangan, penguatan dan transformasi sistem pendidikan Islam di Malaysia.

Published: October 2018

CONTEXT:
Successful treatment approaches are needed for obesity in adolescents. Motivational interviewing (MI), a counseling approach designed to enhance behavior change, shows promise in promoting healthy lifestyle changes.

OBJECTIVE:
Conduct a systematic review of MI for treating overweight and obesity in adolescents and meta-analysis of its effects on anthropometric and cardiometabolic outcomes.

DATA SOURCES:
We searched Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, PsychINFO, Web of Science, Cochrane Library, and Google Scholar from January 1997 to April 2018.

STUDY SELECTION:
Four authors reviewed titles, abstracts, and full-text articles.

DATA EXTRACTION:
Two authors abstracted data and assessed risk of bias and quality of evidence.

RESULTS:
Seventeen studies met inclusion criteria; 11 were included in the meta-analysis. There were nonsignificant effects on reducing BMI (mean difference [MD] −0.27; 95% confidence interval −0.98 to 0.44) and BMI percentile (MD −1.07; confidence interval −3.63 to 1.48) and no discernable effects on BMI z score, waist circumference, glucose, triglycerides, cholesterol, or fasting insulin. Optimal information size necessary for detecting statistically significant MDs was not met for any outcome. Qualitative synthesis suggests MI may improve health-related behaviors, especially when added to complementary interventions.

LIMITATIONS:
Small sample sizes, overall moderate risk of bias, and short follow-up periods.

CONCLUSIONS:
MI alone does not seem effective for treating overweight and obesity in adolescents, but sample size and study dose, delivery, and duration issues complicate interpretation of the results. Larger, longer duration studies may be needed to properly assess MI for weight management in adolescents.
Krónikus, nem bakteriális, multicentrikus osteomyelitis a mandibulában

Published: October 2018

Abstract: Chronic nonbacterial osteomyelitis is a sterile inflammatory osteitis that most commonly develops in the long bones, but it can occur in any bone. Mandibular lesions are found in 1.5–3% of disease foci in patients and it is poorly characterized in the maxillofacial surgery literature due to the use of inconsistent terminology. The purpose of this study was to present the clinical experience of chronic nonbacterial multicentric osteomyelitis and a collection of research and information of the disease. This is a retrospective study of 2 cases with mandibular lesions radiographically consistent with osteomyelitis without infection. Medical records were reviewed for history, clinical features, imaging and pathology. The study included 2 patients (2 females, age of 17 and 43 years). Both reported mandibular pain and swelling, radiographic finding of multifocal intraosseal inflammatory lesions. Computed tomography scans typically showed expansion of the affected mandible with sclerosis of the medullary space, small foci of poorly defined lytic destruction with lamellated periosteal reaction. Both patients showed a long ineffective antibiotic therapy and recurrent flare-ups of inflammation. After the proper course of treatment (nonsteroid and steroid therapy), a long painless period was reached. Chronic multicentric nonbacterial osteomyelitis has been reported to be uncommon in the mandible, but it may be more common with correct diagnosis, typified by recurrent pain and swelling with characteristic pathologic and radiologic features. The current treatment modalities include nonsteroidal anti-inflammatory drugs or steroids. Orv Hetil. 2018; 159(43): 1761–1766.

Authors: Passarella Rossi , Taha Zahari 
Published: October 2018

This paper described the Abaqus/Explicit 6.7 simulation work performed to study the frontal crash impact condition for an in-house designed and produced lightweight solar vehicle main structural body. The structural body was fabricated from aluminum hollow pipes welded together. The analysis is needed to safeguard the safety of the vehicle driver. The dynamic response of the vehicle structure when subjected to frontal impact condition was simulated, according to NASA best practice for crash test methodology. The simulated speed used was based on the NHTSA standard. Comparison of the analysis with the standard Head Injury Criteria (HIC) and Chest Injury Criteria (CIC) revealed that the driver of the designed vehicle would not be risk because the acceleration resultant was found to be lower than 20 G.Â The analysis also proved that structural component was able to protect the driver during any frontal collision incident. However, to ensure the safety of the driver, safety precautions such as the use of seatbelt and helmet as well as driving below the speed limit are recommended.DOI:Â 10.18495/comengapp.12.085096

Abstract Binarization is an initial step in document image analysis for differentiate text area from background. Determination of binarization technique is really important to retrieve all the text information especially from degraded document image. This paper explains about adaptive binarization using Gatosâ€™s method. Gatosâ€™s method is doing preprocessing, foreground estimation using Sauvolaâ€™s method, background estimation, upsampling, final thresholding and postprocessing. In this paper, Sauvolaâ€™s method is final thresholding from Wiener filter image result and source image, and count F-Measure from both of these binary image results. By using optimum constant value on k value, n local window, Ksw and Ksw1, Gatosâ€™s method can produced binary image better than Sauvolaâ€™s method based on F-Measure value. Sauvolaâ€™s method produces average value F=84,62%, Sauvolaâ€™s method with Wiener filter produces average value F=99.06% and Gatosâ€™s method produces average value F=99,43%.

Online product reviews is considered as a major informative resource which is useful for both customers and manufacturers. The online reviews are unstructured-free-texts in natural language form. The task of manually scanning through huge volume of review is very tedious and time consuming. Therefore it is needed to automatically process the online reviews and provide the necessary information in a suitable form. In this paper, we dedicate our work to the task of classifying the reviews based on the opinion, i.e. positive or negative opinion. This paper mainly addresses using ensemble approach of Support Vector Machine (SVM) for opinion mining. Ensemble classifier was examined for feature based product review dataset for three different products. We showed that proposed ensemble of Support Vector Machine is superior to individual baseline approach for opinion mining in terms of error rate and Receiver operating characteristics Curve.
