PENGGUNAAN MEDIA TANGRAM DALAM PEMBELAJARAN MATEMATIKA PADA MATERI KESEBANGUNAN DI KELAS IX MTs SITI MARIAM BANJARMASIN
Authors: Rah Sa , Rahmah Lathifatur 
Published: June 2017

Materi kesebangunan secara teoritis dianggap sulit karena siswa kurang memahami apa perbedaan antara kesebangunan dan kekongruenan suatu bangun datar. Selain materinya memang sulit, dalam menyajikan materi guru jarang menggunakan media yang dapat menarik minat siswa dan bersifat konkrit terhadap pelajaran matematika. Oleh karena itu perlu diciptakan suatu kondisi pembelajaran yang dapat mengakrabkan matematika dengan anak, diantaranya melakukan suatu pembelajaran dengan menggunakan media tangram. Penelitian ini bertujuan untuk mendeskripsikan penggunaan media tangram dalam pembelajaran matematika pada materi kesebangunan dan untuk mengetahui faktor-faktor apa saja yang mempengaruhi penggunaan media tangram dalam pembelajaran matematika pada materi kesebangunan di kelas IX MTs Siti Mariam Banjarmasin tahun pelajaran 2014/2015.Jenis penelitian ini adalah penelitian lapangan dengan pendekatan kualitatif dengan analisis deskriptif kualitatif. Subjek dalam penelitian ini adalah 1 orang guru yang mengajar matematika di kelas IX.B dan seluruh siswa kelas IX.B yang berjumlah 25 orang. Objek dalam penelitian ini adalah media tangram yang digunakan dalam pembelajaran matematika materi kesebangunan.Hasil penelitian menunjukkan bahwa penggunaan media tangram pada pembelajaran matematika pada materi kesebangunan guru membagi siswa yang berjumlah 25 siswa menjadi 5 kelompok yang terdiri 5 siswa. Hasil belajar siswa pada saat berkelompok mencapai 83 dengan kategori amat baik. Faktor-faktor yang mempengaruhi media tangram dalam pembelajaran matematika pada materi kesebangunan seperti faktor siswa yaitu minat dan keaktifan siswa, faktor guru, serta faktor sarana prasarana dan fasilitas sekolah, sudah dikatakan cukup baik karena sudah memenuhi 4 faktor tersebut.
The Impact of Enrollment in an OER Course on Student Learning Outcomes
Authors: Grewe Kim , Davis William Preston 
Published: June 2017

<p class="3">Open Educational Resources (OER) are gaining acceptance as legitimate and effective teaching materials in higher education, particularly in 2-year institutions. Despite the steady growth in the availability and use of OER, there have been relatively few studies on the efficacy of OER and student achievement. This study analyzed the effect enrollment in an OER course had on student academic achievement when controlling for prior academic achievement in an introductory online history course at a large community college. Correlation analysis and simple linear regression were conducted. The results of this research indicate a significant positive moderate correlation between OER and student achievement. The study provided a process by which future, more rigorous efficacy studies can be conducted.</p>
Evaluating NTU’s OpenCourseWare Project with Google Analytics: User Characteristics, Course Preferences, and Usage Patterns
Authors: Sheu Feng-Ru , Shih Meilun 
Published: June 2017

<p class="3">As freely adoptable digital resources, OpenCourseWare (OCW) have become a prominent form of Open Educational Resources (OER). More than 275 institutions in the worldwide OCW consortium have committed to creating free access open course materials. Despite the resources and efforts to create OCW worldwide, little understanding of its use exists. This paper reports OCW project development at National Taiwan University (NTU) and investigates its use with Google Analytics. Reports include strategic plans to overcome challenges to OCW creation and implementation, the project’s growth and maturation, overall use of OCW, and possible future directions. As a result of its 5-year development and of lessons learned, the NTU-OCW experience features: (1) integrating resources on campus and established operating procedures, (2) setting course selection criteria featuring the strength of NTU and Taiwan, (3) providing coherent program support to enhance faculty participation, and (4) adhering strictly to the Creative Commons license. Data from Google Analytics was reviewed for better understanding of the use, characteristics, course preferences, and behaviors of NTU-OCW users. Results show visitors were primarily lifelong learners (65%) in informal learning settings. Statistics indicate an overall successful use of NTU-OCW for Chinese speaking users, especially in urban areas where information and communication technology is more developed. Potential impacts and future improvements are discussed, including how to promote usage of OCW courses for on and off campus users, adding rating features and indexing for customizing search, and integrating OCW into the learning management system (LMS) as part of OER.</p>

Core Ideas
X‐ray microtomography.
An image‐based approach to determine soil pore distributions.
Integration between information obtained in different spatial resolutions.
Soil pores form interconnected networks that directly or indirectly influence transport processes in soils. There is great interest in estimating pore properties such as size and shape from three‐dimensional (3D) images as a way of understanding linkages between structure and function. This work evaluates the applicability of an approach to measure pore‐size distributions (PSDs) from 3D images of four soils with contrasting physical properties. Images were obtained with a benchtop X‐ray microtomograph system at spatial resolutions of 4, 6, 12, and 30 μm by varying the size of the samples from 0.5 cm to about 4 cm in diameter. Pore‐size distributions obtained at each image resolution were fitted with lognormal distribution functions with r2 ranging from 0.81 to 0.98. The four PSDs for a given soil were combined by identifying crossover points in the lognormal distributions. When pore sizes where imaged at more than one resolution, the criterion followed to eliminate redundant information was that large pore sizes are better represented in low resolution images of large sample sizes, and vice versa. Pore‐size data from four truncated PSDs were fitted with a lognormal distribution function to obtain a final (global) PSD for each soil. Global PSDs obtained with the image‐based approach correlated well with PSDs measured by mercury intrusion porosimetry and also with PSDs derived from soil water retention curves, showing potential for application of this image‐based approach to soils.
Modelling river runoff and estimating its weather-related uncertainty for 11 large-scale rivers located in different regions of the globe

Published: June 2017

Abstract
In order to study the possibility of reproducing river runoff with making use of the land surface model Soil Water–Atmosphere–Plants (SWAP) and information based on global data sets 11 river basins suggested within the framework of the Inter-Sectoral Impact Model Intercomparison Project and located in various regions of the globe under a wide variety of natural conditions were used. Schematization of each basin as a set of 0.5° × 0.5° computational grid cells connected by a river network was carried out. Input data including atmospheric forcing data and land surface parameters based, respectively, on the global WATCH and ECOCLIMAP data sets were prepared for each grid cell. Simulations of river runoff performed by SWAP with a priori input data showed poor agreement with observations. Optimization of a number of model parameters substantially improved the results. The obtained results confirm the universal character of SWAP. Natural uncertainty of river runoff caused by weather noise was estimated and analysed. It can be treated as the lowest limit of predictability of river runoff. It was shown that differences in runoff uncertainties obtained for different rivers depend greatly on natural conditions of a river basin, in particular, on the ratio of deterministic and random components of the river runoff.
Modulating Mitophagy in Mitochondrial Disease
Authors: Dombi Eszter , Mortiboys Heather , Poulton Joanna 
Published: June 2017

Mitochondrial diseases may result from mutations in the maternally-inherited mitochondrial DNA (mtDNA) or from mutations in nuclear genes encoding mitochondrial proteins. Their bi-genomic nature makes mitochondrial diseases a very heterogeneous group of disorders that can present at any age and can affect any type of tissue.The autophagic-lysosomal degradation pathway plays an important role in clearing dysfunctional and redundant mitochondria through a specific quality control mechanism termed mitophagy. Mitochondria could be targeted for autophagic degradation for a variety of reasons including basal turnover for recycling, starvation induced degradation, and degradation due to damage. While the core autophagic machinery is highly conserved and common to most pathways, the signaling pathways leading to the selective degradation of damaged mitochondria are still not completely understood. Type 1 mitophagy due to nutrient starvation is dependent on PI3K (phosphoinositide 3-kinase) for autophagosome formation but independent of mitophagy proteins, PINK1 (PTEN-induced putative kinase 1) and Parkin. Whereas type 2 mitophagy that occurs due to damage is dependent on PINK1 and Parkin but does not require PI3K.Autophagy and mitophagy play an important role in human disease and hence could serve as therapeutic targets for the treatment of mitochondrial as well as neurodegenerative disorders. Therefore, we reviewed drugs that are known modulators of autophagy (AICAR and metformin) and may affect this by activating the AMP-activated protein kinase signaling pathways. Furthermore, we reviewed the data available on supplements, such as Coenzyme Q and the quinone idebenone, that we assert rescue increased mitophagy in mitochondrial disease by benefiting mitochondrial function.
VDAC1 as a Player in Mitochondria-Mediated Apoptosis and Target for Modulating Apoptosis
Authors: Shoshan-Barmatz Varda , Krelin Yakov , Chen Quan 
Published: June 2017

Background:
The voltage-dependent anion channel 1 (VDAC1), an outer mitochondria
membrane protein, functions as a mitochondrial governor, controlling transport of
metabolites in and out of the mitochondria and energy production, while also coordinating
glycolysis and oxidative phosphorylation. VDAC1 plays a key role in mitochondria-mediated
apoptosis by functioning in the release of apoptotic proteins located in the inter-membranal
space and due to its association with pro- and anti-apoptotic proteins. Thus, VDAC1 is considered
as a promising target for controlling apoptosis.

Methods:
We reviewed published data presenting accumulated evidence suggesting that
VDAC1 oligomerization represents an important step in the intrinsic mitochondria-mediated
apoptosis pathway.

Results:
The published data support the proposal that VDAC1 oligomerization leads to the
formation of a large pore that allows the release of pro-apoptotic proteins to the cytosol,
thereby, activation of apoptosis. Evidence for the relationship between VDAC1 expression
levels and induction of apoptosis are presented. This includes the finding that almost all apoptosis
stimuli induce VDAC1 over-expression shifting VDAC1 from a monomeric to an oligomeric
assembly, corresponding to the Cyto c release channel. Copounds or conditions inducing
VDAC1 over-expression, VDAC1 oligomerization and apoptosis are presented. Likewise,
VDAC1-interacting molecules, that inhibit both VDAC1 oligomerization and apoptosis
are also presented.

Conclusion:
This review highlights the findings about VDAC1 oligomerization as a potential
target for controlling apoptosis, specifically using drugs to induce apoptotic cell death in cancer
and inhibit apoptosis in neurodegenerative diseases, as well as possible VDAC1-based
therapeutic applications.
The Influence of Obese Insulin-Resistance on the Outcome of the Ischemia/Reperfusion Insult to the Heart
Authors: Shinlapawittayatorn Krekwit , Chattipakorn Siriporn C. , Chattipakorn Nipon 
Published: June 2017

Background:
Obese insulin-resistance is one of the most important risk factor
for cardiovascular diseases including ischemic heart disease (IHD). Growing evidences
suggest that the susceptibility to myocardial ischemia-reperfusion (I/R) injury is increased
in an obese insulin-resistance condition. Based on the currently available evidence from
human and animal studies, this review mainly focuses on the influence of obese insulinresistance
on the outcome of the I/R insult to the heart. Moreover, we have discussed
whether improving insulin sensitivity by pharmacological interventions could ameliorate
reperfusion induced myocardial injury.

Methods:
The electronic database Pubmed was used as the source of selected peerreviewed
research articles published in English. Both pre-clinical studies and clinical trials
were obtained using obesity, insulin resistance, ischemia-reperfusion injury and myocardial
infarction as keywords.

Results:
Twenty-seven pre-clinical studies were obtained using obesity, insulin resistance,
and cardiac ischemia-reperfusion injury as keywords, and five clinical trials were
obtained using obesity, insulin resistance, and myocardial infarction as keywords. The
underlying mechanisms responsible for the exacerbation of I/R injury in obese insulinresistance
were the main subject of our review.

Conclusion:
The findings of this review suggest that the susceptibility to I/R injury is increased
in an obese insulin-resistance condition. However, the underlying mechanisms responsible
for the exacerbation of I/R injury in obese insulin-resistance have not been fully
elucidated, but increased basal oxidative stress, the impairment of anti-oxidant capacities,
insulin signaling and pro-survival signaling and increased inflammation, likely play an
important role.
Relationship between anterior occlusion and frontal sinus size
Authors: Said Omar T. , Rossouw P. Emile , Fishman Leonard S. , Feng Changyong 
Published: June 2017

ABSTRACT

Objective:
To determine the relationship between anterior occlusion and frontal sinus size.

Methods:
The patient database at the Eastman Institute for Oral Health, University of Rochester, was searched for male patients older than 15 years and females older than 13 years of age. After applying inclusion and exclusion criteria, participants' photos and lateral cephalometric and posteroanterior radiographs were examined then classified into a control class I group (n = 20, 15.7 ± 2.7 years) and eight malocclusion groups (n = 136, 16.1 ± 2.1 years). The frontal sinus area on the lateral cephalometric radiograph and on the posteroanterior radiograph were measured and compared between groups.

Results:
One-way analysis of variance demonstrated a significant difference among all nine groups (P = .0001). Pairwise comparison showed a significant difference between the class I group and all other malocclusion groups (P &lt; .05) except the edge-to-edge group for both radiographs and except the bimaxillary protrusion group for the lateral cephalometric radiographs. Tukey's method was not able to demonstrate a significant difference among the subgroups of skeletal malocclusions (P &gt; .05). Linear regression analyses with stepwise model selection demonstrated that anterior cranial base, mandibular plane angle, and upper incisor inclination commonly have a significant effect on frontal sinus size.

Conclusion:
The frontal sinus size could be used as an indicator of harmonious anterior occlusion. There were no differences among the subgroups of each skeletal malocclusion. The anterior cranial base, facial height, and maxillary incisor inclination appear to have a significant effect on frontal sinus size.
A tomada de Troia contada por Eneias
Authors: De Freitas Eduardo da Silva 
Published: June 2017

Este artigo analisa a narrativa do episódio do Saque de Troia feita por Eneias no “Livro II” da Eneida. A lenda era bastante conhecida na Antiguidade e Virgílio criou uma representação complexa ao transferir o relato do narrador principal para Eneias. O acontecimento assume um tom bastante trágico, porque o relato é feito do ponto de vista do vencido. Consequentemente, o herói ressalta que a derrota dos troianos aconteceu porque os gregos mentiram. Além disso, os gregos são representados como selvagens, enquanto os troianos são corajosos. Por fim, Eneias sugere que a fuga foi um ato inevitável e necessário para a salvação de sua família, de seus companheiros e dos deuses da cidade. ---DOI: http://dx.doi.org/10.25094/rtp.2017n22a360

Os Cautos Causos de Glauco Mattoso
Authors: Hansen João Adolfo 
Published: June 2017

O artigo trata da forma cômico-satírica do livro Raymundo Curupyra, o Caypora, de Glauco Mattoso. Lembra que seus 200 sonetos de gênero baixo, verso decassílabo e rimas toantes abba/abba/cdc/dcd compõem, na sequência em que são ordenados, conjuntos narrativos. Jocosamente intitulados de “cautos causos”, eles formam um romance ironicamente lírico e sua matéria são as temporalidades das ações de Raymundo Curupyra. As inadequações cômicas de seus atos são narradas por Craque, “perfeito/ malandro brasileiro da selecta/ralé miscigenada” (Soneto 107), que salta, aidético e trágico, do edifício Martinelli, derrotado por si mesmo e por São Paulo. O artigo propõe que o princípio – e o limite – dos atos da fala lírica de Craque é a miséria que fornica com a luxúria. Ou seja: o artigo propõe que o livro efetua a galhofa cansada ou a melancolia burlesca próprias de um retrato sério-cômico de São Paulo e da sociedade brasileira contemporânea. ---DOI: http://dx.doi.org/10.25094/rtp.2017n22a444
The Role of Exercise and Patient Education in the Noninvasive Management of Whiplash
Authors: Rebbeck Trudy 
Published: June 2017

Synopsis The majority of people with whiplash-associated disorder do not have neurological deficit or fracture and are therefore largely managed with nonsurgical interventions such as exercise, patient education, and behavioral-based interventions. To date, clinical guidelines, systematic reviews, and the results of high-quality randomized controlled trials recommend exercise and patient education as the primary interventions for people in both acute and chronic stages after injury. However, the relatively weak evidence and small effect sizes in individual trials have led authors of some systematic reviews to reach equivocal recommendations for either exercise or patient education, and led policy makers and funders to question whether the more expensive intervention (exercise) should be funded at all. Physical therapists, one of the most commonly consulted professionals treating individuals with whiplash-associated disorder, need to look beyond the evidence for insights as to what role patient education and exercise should play in the future management of whiplash. This clinical commentary therefore will review the evidence for exercise, patient education, and behavioral-based interventions for whiplash and provide clinical insight as to the future role that exercise and patient education should play in the management of this complex condition. Possible subgroups of patients who may best respond to exercise will be explored using stratification based on impairments, treatment response, and risk/prognostic factors.

An Integrated Model of Chronic Whiplash-Associated Disorder
Authors: Walton David M. , Elliott James M. 
Published: June 2017

Synopsis The development of persistent symptoms following whiplash injury from a motor vehicle collision is common and contributes substantially to societal and personal costs. The popular Quebec Task Force classification system of whiplash-associated disorders (WADs) was meant to function as a prognostic and intervention decision aid, but its usefulness has been questioned. Emerging evidence highlights the heterogeneity of WAD by demonstrating physical and psychological impairments that are unique to those who develop persistent symptoms. These impairments are not recognized in the Quebec Task Force classification system. The purpose of this clinical commentary is to describe an integrated model that focuses on how psychological and neurobiological factors interact with, and are influenced by, existing personal and environmental factors to contribute to the development of chronic WAD. The model has been developed through more than 20 years of work in the field, consultation with experts, in-depth synthesis of existing evidence, and new evidence from the authors' own research programs. A subtheme is that a point of convergence currently exists between the psychological, physiological, and social determinants of health literature that can further explain the complex presentation of WAD. The new model is proposed to orient future research toward more interdisciplinary efforts across nontraditional fields, including data scientists and consumers, to clarify the WAD condition.
