Authors: Adkins Megan , Bice Matthew  R. , Worrell Vicki , Unruh Nita 
Published: September 2017

Schools continue to integrate the use of technology, and gymnasiums are not an exception. The purpose of the study was to determine the comfort level of Physical Education teachers integrating technology in the gymnasium, determine types of professional development provided for technology use, and potential barriers associated with technology usage. A survey of 179 practicing Physical Education teachers located in the Midwest completed an online questionnaire. Results indicated Physical Education teachers were comfortable integrating technology but reported inadequate professional develop on technology device implementation. These findings suggest Physical Educators are willing to integrate technology but the professional development and resources available to accomplish this is lacking. Future research should examine PETE program offerings, and additional PD opportunities offered by SHAPE America within the area of technology and Physical Education.

Published: October 2017

Background:
Patients with spinal metastasis from cancer of unknown primary origin have limited life expectancy and poor quality of life. Surgery and radiation therapy remain the main treatment options, but, to our knowledge, there are limited data concerning quality-of-life improvement after surgery and radiation therapy and even fewer data on whether surgical intervention would affect quality of life.

Methods:
Patients were enrolled between January 2009 and January 2014 at the Changzheng Hospital, Shanghai, People’s Republic of China. The quality of life of 2 patient groups (one group that underwent surgery followed by postoperative radiation therapy and one group that underwent radiation therapy only) was assessed by the Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire during a 6-month period. A subgroup analysis of quality of life was performed to compare different surgical strategies in the surgical group.

Results:
A total of 287 patients, including 191 patients in the group that underwent surgery and 96 patients in the group that underwent radiation therapy only, were enrolled in the prospective study; 177 patients completed all 5 checkpoints and 110 patients had died by the final checkpoint. The surgery group had significantly higher adjusted quality-of-life scores than the radiation therapy group in each domain of the FACT-G questionnaire (all p < 0.05). Subgroup analysis showed that adjusted functional and physical well-being scores were higher in the circumferential surgical decompression group.

Conclusions:
Surgery followed by postoperative radiation therapy improved and maintained quality of life in patients with spinal metastasis from cancer of unknown primary origin in the 6-month assessment. In terms of surgical strategies, circumferential decompression seems better than laminectomy alone in quality-of-life improvement.

Blood Conservation Using Tranexamic Acid Is Not Superior to Epsilon-Aminocaproic Acid After Total Knee Arthroplasty
Authors: Boese Clifford Kent , Centeno Leslie , Walters Ryan W. 
Published: October 2017

Background:
Epsilon-aminocaproic acid (EACA) and tranexamic acid (TXA) are synthetic amino acid derivatives that interfere with fibrinolysis, promoting hemostasis by pharmacological means. Although both drugs have been shown to decrease blood loss with a minimal risk of thromboembolic adverse events following cardiac and vascular surgery, we are aware of only 1 published trial that directly compared the antifibrinolytic effects of EACA with those of TXA after total knee arthroplasty (TKA). The primary aim of this prospective, randomized, controlled trial was to determine whether TXA provides superior blood conservation following TKA compared with that provided by EACA.

Methods:
A total of 194 patients scheduled to undergo a primary unilateral TKA in the same community-based hospital were prospectively randomized to receive intravenous EACA (n = 96) or TXA (n = 98). Both the patients and the operating surgeons were blinded to the treatment assignments. Primary outcome measures included transfusions, estimated blood loss, and the drop in the hemoglobin (Hgb) level. Secondary outcomes measures included the change in the serum creatinine level, postoperative complications, and length of hospital stay.

Results:
Although the patients who received TXA averaged less estimated blood loss than the patients who received EACA (t185 = 2.18, p = 0.031; mean difference = 144.2 mL, 95% confidence interval = 13.62 to 274.78 mL), no transfusions were required in either group. We observed no statistically significant or clinically relevant between-group differences in the change in Hgb or serum creatinine level, postoperative complications, or length of hospital stay.

Conclusions:
Although the estimated blood loss was significantly greater in the EACA group, no transfusions were required and no significant between-group differences were observed for any other outcomes measured. We concluded that EACA may be an acceptable alternative to TXA for blood conservation following TKA, although replication of our results in noninferiority trials is necessary.

Assessment of climate change impact on rainfall for studying water availability in upper Mahanadi catchment, India
Authors: Jaiswal R. K. , Tiwari H. L. , Lohani A. K. 
Published: October 2017

AbstractThe paper deals with the projected rainfall for eight rain gauge stations located in the upper Mahanadi catchment in Chhattisgarh state of India and corresponding changes on the water availability in few reservoirs of the catchment. Rescaled predictors obtained from NCEP were used and statistically tested for selection of best-fit set of predictors using percentage reduction methods. The calibrated and validated models were used to generate multiple series for early, mid and late century periods, i.e. for 2020–2035 (FP-1), 2046–2064 (FP-2) and 2081–2099 (FP-3) under CMIP5 climatic forcing conditions of RCP2.6, RCP4.5 and RCP8.5 using predictors data of CanESM2, Canadian GCM. The comparisons of future predicted rainfall with the base period (1981–2003) showed mixed trends, viz. declining trend at five stations, both declining and increasing trend at two stations, and increasing trend at one station. The predicted reduced rainfall during August and September attribute to a significant impact on paddy cultivation and industrial development. The analysis of future catchment rainfall on five important reservoirs in this region indicated a reduction of 12–29% seasonal rainfall with respect to the base period rainfall; while for one reservoir not much variation (–7 to 5%) in the rainfall was noted, possibly due to the large catchment area.
SWAT modeling of hydrology, sediment and nutrients from the Grand River, Ontario
Authors: Hanief Aslam , Laursen Andrew E. 
Published: October 2017

Abstract
The Grand River watershed (GRW) is an important agricultural area in Southern Ontario. Land use has been modified by various human endeavors, altering hydrology and increasing export of sediment and nutrients. The objective of this study was to predict spatial and temporal patterns of hydrology, and export of sediment and nutrients from the GRW to Lake Erie using the Soil and Water Assessment Tool (SWAT) model. The Sequential Uncertainty FItting (SUFI2) program was used to calibrate and validate stream flow for years 2001–2010. Calibration and validation of the SWAT model for monthly stream flow at York indicated good model performance (R2, NSE, and PBIAS = 0.64, 0.63 and 7.1 for calibration (2001–2005); = 0.82, 0.74 and 0.2, for validation (2006–2010)). The model was applied to predict sediment and nutrient export from the GRW into Lake Erie. Predicted loading at Dunnville (near the mouth) was 2.3 × 105 tonnes y−1 total suspended sediment, 7.9 × 103 tonnes y−1 TN, and 2.3 × 102 tonnes y−1 TP. This SWAT model can now be used to investigate the relative effects of best management practices, and to forecast effects of climate change, on sustainable water management, hydrology, and sediment and nutrient export to Lake Erie.

Abstract
Small-scale irrigation continues to cushion the food security gap in sub-Saharan Africa. Irrigation is largely governed by water availability, soil type and crop water requirements, among other factors. Thus, a study was conducted to assess the suitability of various water sources for irrigation in northern Ghana. Specifically, the study sought to assess quality of water sources in the Savelugu, Kasena-Nankana East, and Nabdam districts for small-scale irrigation development. The water quality parameters used were: pH, electrical conductivity (ECw), sodium adsorption ratio (SAR), sodium percent (Na%), soluble sodium percentage (SSP), magnesium adsorption ratio (MAR), Kelley's ratio (KR), total hardness (TH), chloride (Cl), Escherichia coli, and fecal coliforms. While we found most of the irrigation water sources, including small reservoirs, dams, wells and rivers suitable, few unsuitable irrigation water sources were also identified. Overall, the study found that opportunities for scaling small-scale irrigation exist in all the sites. The knowledge generated from this study will guide irrigation water use, and agricultural policy for sustainable smallholder irrigation development in the region.
Developing Social Media-Based Suicide Prevention Messages in Partnership With Young People: Exploratory Study
Authors: Robinson Jo , Bailey Eleanor , Hetrick Sarah , Paix Steve , O'Donnell Matt , Cox Georgina , Ftanou Maria , Skehan Jaelea 
Published: October 2017

Background
Social media is increasingly being used by young people for health-related issues, including communicating about suicide. Due to the concerns about causing distress or inducing suicidal thoughts or behaviors, to date young people neither have been engaged in the development of social media–based suicide prevention interventions nor have interventions focused on educating young people about safe ways to communicate about suicide online. Given the potential that social media holds to deliver messages to vast numbers of people across space and time and the fact that young people often prefer to seek help from their friends and peers, safely educating and engaging young people to develop suicide prevention messages that can be delivered via social media is an obvious next step.

Objectives
The objectives of this study were to (1) provide education to a small number of secondary school students about safe ways to communicate about suicide via social media; (2) engage the same young people in the development of a suite of social media–based suicide prevention multimedia messages; (3) assess the impact of this on participants; and (4) assess the acceptability and safety of the messages developed.

Methods
This study involved two phases. In phase 1, 20 participants recruited from two schools took part in an 8- to 10-week program during which they were provided with psychoeducation about mental health and suicide, including how to talk safely about suicide online, and they were then supported to design and develop their own media messages. These participants completed an evaluation questionnaire at the conclusion of the program. In phase 2, a larger group of participants (n=69), recruited via an opt-in process, viewed the media messages and completed a short questionnaire about each one.

Results
Participants in phase 1 enjoyed the program and reported that they learned new skills, such as how to talk safely about suicide online, and felt more able to provide emotional support to others (16/20, 80%). No participants reported that the program made them feel suicidal. Participants in phase 2 generally rated the media messages as safe and acceptable, although some messages were rated more highly than others.

Conclusions
This study suggests that young people can be safely engaged in developing suicide prevention messages, which can be disseminated via social media. Engaging young people in this process may improve the traction that such campaigns will have with other young people. The study also suggests that educating young people regarding how to talk safely about suicide online has multiple benefits and is not associated with distress. Overall, these findings pave the way for new approaches to prevent suicide among young people.

Authors: Soares CJ , Rosatto CMP , Carvalho VF , Bicalho AA , Henriques JCG , Faria-e-Silva AL 
Published: October 2017

SUMMARY

Objectives:
To compare radiopacity and porosity as expressed by the presence of voids in restorations carried out using bulk-fill and incremental filling techniques to restore large mesio-occlusal-distal (MOD) cavities.

Methods:
Fifty-five molars with MOD preparations were incrementally filled with Filtek Z-350XT (Z350XT) or bulk-fill composite: Filtek Bulk Fill/Z-350XT (FBF/Z350XT), Venus Bulk Fill/Charisma Diamond (VBF/CHA), SDR/Esthet-X HD (SDR/EST-X), Tetric EvoCeram Bulk Fill (TEC). Digital radiographic images (Vistascan scanner) were taken of restored molars and analyzed at the gingival and isthmus floors. Radiodensity measurements were performed using standardized points symmetrically distributed over each region of composite and tooth structure. Three calibrated evaluators visually assessed the presence of voids. Confidence intervals were calculated, and data were analyzed using analysis of variance and χ2 tests.

Results:
TEC and VBF/CHA showed significantly higher radiodensities, while the lowest values were observed for FBF/Z350XT and Z350XT. Radiodensity at the cervical regions tended to be greater than that found at the isthmus floor. The lowest incidence of voids was found for VBF/CHA, whereas the incremental insertion technique resulted in the highest rate of voids.

Conclusion:
Bulk-fill composite resin demonstrated an adequate level of radiodensity and a reduced presence of voids compared with the incremental filling technique.

ASPECTOS A CONSIDERAR FRENTE AL CONCEPTO DE INTELIGENCIA EN NIÑOS PRIVADOS SOCIOCULTURALMENTE: LA IMPORTANCIA DE LAS EVALUACIONES DINÁMICAS
Authors: Cabezas Corcione Andrés 
Published: September 2017

El constructo inteligencia se ha utilizado principalmente para medir la capacidad que tienen los individuos de resolver un problema, correlacionando el cociente intelectual con el rendimiento escolar. Esto ha generado una visión estática y poco modificable de ciertas habilidades cognitivas, con resultados poco favorables en niños de contextos rurales o deprivados socioculturalmente, evidenciando el impacto de la cultura en las diferencias individuales. En primera instancia, se realiza un breve barrido histórico sobre el concepto inteligencia, para luego señalar alcances y limitaciones de la medición del cociente intelectual, discutiendo el concepto de retardo mental sociocultural que no busca afirmar una etiología cultural, sino comprender y resaltar la importancia del contexto y las diferencias individuales en las habilidades cognitivas. Finalmente se concluye que la inteligencia y su medición deben cumplir con el objetivo de identificar fortalezas y no sólo déficits en el rendimiento escolar, enfatizando la aplicación de mediciones positivas dinámicas.

Gangguan 1 fasa ke tanah dapat menyebabkan terjadinya gangguan sympathetic trip yang menimbulkan arus urutan nol (arus residu) pada fasa yang terganggu. Penyulang yang memiliki sistem jaringan paralel seperti penyulang Ngurah Rai I dan Ngurah Rai II sangat rentan terjadinya gangguan sympathetic trip, karena relay GFR (Ground Fault Relay) pada penyulang Ngurah Rai I dan Ngurah Rai II tidak bisa mengamankan gangguan tersebut, maka untuk mengatasi gangguan sympathetic trip pada penyulang Ngurah Rai I dan Ngurah Rai II pemasangan relay DGR (Directional Ground Relay) akan mencegah terjadinya gangguan tersebut, dan sistem keandalan penyulang Ngurah Rai I dan Ngurah Rai II tetap terjaga. Hasil analisis perhitungan relay DGR untuk menangani gangguan sympathetic trip didapatkan besar nilai setting relay yaitu = 9.334 A, SI, Waktu trip Arus gangguan t = 0.297, ZCT = 1 A, GPT = 34.64 kV. Jadi untuk mengatasi gangguan sympathetic trip, relay DGR sangat diperlukan jika jaringan atau penyulang beroprasi secara loop dan letaknya berdekatan satu bus.
