Authors: Moreno Machado Mónica Alejandra , Arenas Hernández Jorge Enrique , Ramón Valencia Jacipt Alexander 
Published: March 2018

La investigación apunta al conocimiento del impacto ambiental negativo generado por el uso de palancas en la actividad minera subterránea en el período 2006-2013 en el departamento de Norte de Santander. La fecha de otorgamiento de las licencias ambientales permitió definir con precisión los volúmenes de explotación y en consecuencia las cantidades de madera necesarias para la construcción de las estructuras de fortificación, más específicamente las palancas. A la fecha de la investigación se encuentran activas ciento treinta y siete (137) licencias de minería de carbón cuya presencia se hace en diecisiete de los cuarenta municipios de la jurisdicción. Los municipios de Cúcuta, El Zulia y Sardinata poseen el 62 % de las concesiones. En cuanto al uso de la madera para la fortiiación de las minas, tan solo el 29.5 % es de origen legal. En la actividad utilizan setenta y seis tipos de madera de diferentes especies, sin embargo la especie de mayor uso es la pino pátula Pinus patula) con el 38.6 % de preferencia. Con respecto a la pérdida de cobertura vegetal en el área de intervención, se realizó una revisión documental de todos y cada uno de los títulos mineros que en el período investigado estuvieran realizando explotación de carbón. Posteriormente se evaluó cada título minero, determinando que la deforestación en el período de estudio alcanzó 449 hectáreas equivalente al 1.55 % del área ocupada por la concesión. De igual manera se pudo establecer que desde 1990 a 2006 se deforestaron 4.824 hectáreas que corresponden al 18 % del área total de los títulos mineros explotados. La autoridad ambiental inició procesos ambientales sancionatorios al 14 % de los usuarios en el 2012 y al 10.6% de usuarios en el 2013.

Published: March 2018

Background and objectives
Serious fall injuries in the setting of ESKD may be associated with poor access to kidney transplant. We explored the burden of serious fall injuries among patients on dialysis and patients on the deceased donor waitlist and the associations of these fall injuries with waitlisting and transplantation.

Design, setting, participants, & measurements
Our analytic cohorts for the outcomes of (1) waitlisting and (2) transplantation included United States adults ages 18–80 years old who (1) initiated dialysis (n=183,047) and (2) were waitlisted for the first time (n=37,752) in 2010–2013. Serious fall injuries were determined by diagnostic codes for falls plus injury (fracture, joint dislocation, or head trauma) in inpatient and emergency department claims; the first serious fall injury after cohort entry was included as a time-varying exposure. Follow-up ended at the specified outcome, death, or the last date of follow-up (September 30, 2014). We used multivariable Cox proportional hazards models to determine the independent associations between serious fall injury and waitlisting or transplantation.

Results
Overall, 2-year cumulative incidence of serious fall injury was 6% among patients on incident dialysis; with adjustment, patients who had serious fall injuries were 61% less likely to be waitlisted than patients who did not (hazard ratio, 0.39; 95% confidence interval, 0.35 to 0.44). Among incident waitlisted patients (4% 2-year cumulative incidence), those with serious fall injuries were 29% less likely than their counterparts to be subsequently transplanted (hazard ratio, 0.71; 95% confidence interval, 0.63 to 0.80).

Conclusions
Serious fall injuries among United States patients on dialysis are associated with substantially lower likelihood of waitlisting for and receipt of a kidney transplant.

Un punto ciego en la crítica de la economía política, el debate Carlos Pereyra-Bolívar Echeverría
Authors: Ortega Reyna Jaime 
Published: March 2018

<p>Carlos Pereyra y Bolívar Echeverría fueron dos intelectuales que marcaron una época con respecto a la producción del discurso marxista. A finales de los años ochenta, ambos autores entraron en una discusión a propósito de los alcances y límites de dicho discurso. La denominada “crisis del marxismo” había anclado en México, ello obligó a tomar posición: Pereyra lo hizo a través del cuestionamiento de la “crítica de la economía política” y su “punto ciego”, para ello tuvo que hacer un ejercicio de cuestionamiento de la obra de Bolívar Echeverría</p>
A LITERATURA COMO DISPOSITIVO PARA EXPRESSÃO DE CRENÇAS RELIGIOSAS NO CONTEXTO ESCOLAR
Authors: Catarino Elisângela Maura , Purificação Marcelo Máximo , Santana Maria Luzia Da Silva 
Published: March 2018

Esta pesquisa problematiza a literatura como dispositivo para a expressão de crenças religiosas na escola, tendo o objetivo de verificar se as crenças se manifestam no contexto escolar quandoo estudante se depara com elementos da religiosidade nos textos literários. Para isso, foram realizadas observações numa turma do Terceiro Ano do Ensino Médio, que tinha vinte e nove estudantes frequentes, de uma escola pública localizada no entorno do Distrito Federal, no Estado de Goiás. Com fins de análise no presente texto, foram exploradas as falas de quatro estudantes, sendo um do sexo feminino e três do sexo masculino. Foi realizada observação in loco, das aulas da professora e das expressões dos estudantes durante o desenvolvimento do letramento literário, com as obras “Tenda dos Milagres” e “Tieta do Agreste”, ambas de Jorge Amado. Foram registradas as falas dos estudantes e da professora relacionadas àstemáticas crenças e religiosidade.Os dados desta pesquisa reafirmaram a importância da literaturacomo um dispositivo que contribui para que o estudante-leitor construa diferentes olhares em torno da religiosidade. Ao trabalhar com os livros citados o professor não poderá perder de vista que o processo de ensino e aprendizagem é permeado por elementos da historicidade e da cultura do estudante que se constitui - enquanto pessoa - na sua relação com os elementos culturais e sociais. Devido a sociedade brasileira ter variadas matrizes religiosas, nas aulas podem vir à tona choques culturais ou conflitos religiosos. As crenças e diferentes religiosidades estão presentes no cotidiano da escola e têm implicações na leitura e interpretação das obras literárias. Este aspecto reafirma a ideia de que as crenças e a religiosidade não podem ser um tema ignorado, mas sim extensivamente trabalhado pelo professor como um elemento positivador da pluralidade cultural-religiosa existente no país.
Information Quality, Growth Options, and Average Future Stock Returns
Authors: Lyle Matthew R. 
Published: March 2018

ABSTRACT
This study finds that the association between future stock returns and information quality depends on how option-like is the firm's equity. Firms that have more growth options are more option-like. The association between future stock returns and information quality is negative (positive) for those firms with equity that is least (most) option-like. These results are consistent with traditional asset pricing theory and are robust to numerous empirical specifications. Collectively, these findings offer a theoretically based and empirically supported explanation for why prior studies that do not condition on the option-like nature of equity have documented either a positive or no association between information quality and future average stock returns.
Double-blind Randomized Study to Evaluate the Safety and Efficacy of Over-the-counter Tooth-whitening Agents Containing 2.9% Hydrogen Peroxide
Authors: Kim YM , Ha AN , Kim JW , Kim SJ 
Published: March 2018

ABSTRACT

Objectives:
In this double-blind randomized study, we evaluated the safety and efficacy of over-the-counter (OTC) bleaching products that included 2.9% hydrogen peroxide (H2O2) with two methods of application: strip and paint-on.

Methods and Materials:
A commonly used product was selected for each type (strip and paint-on) of OTC bleaching agent. In total, 75 volunteers were assigned randomly into five groups: two test groups (strip and paint-on), two negative control groups (products without H2O2), and one positive control group (dentist-supervised home bleaching). The tooth shade was evaluated with a spectrophotometer and Vita shade guide at baseline and 2 weeks and 4 weeks after use. To document any adverse reactions, such as hypersensitivity or tissue irritation, all patients were examined and the Gingival Index (GI), Plaque Index (PI), and a visual analog scale (VAS) measuring the cold response were obtained.

Results:
There were significant differences among the five groups (p&lt;0.001). The positive control showed the greatest color changes; then, in decreasing order, the strip-type test group, paint-on-type test group, and negative controls. The strip-type bleaching agent was significantly more effective than the paint-on-type agent and the negative control, while it was significantly less effective than the dentist-supervised home bleaching. Regardless of the treatment group, the canines showed greater color changes than did the central or lateral incisors. Some cases of gingival irritation and hypersensitivity were observed, but they were mild and reversible. GI, PI, and VAS scores were not significantly changed.

Conclusions:
Within the limitations of this study, the results indicated that the strip-type and paint-on-type OTC bleaching agents were significantly less efficacious than was dentist-supervised home bleaching; however, they showed acceptable safety and efficacy. The strip-type was more effective than was the paint-on-type in this study.

Published: March 2018

SUMMARYThis work presents the multilayered caries model with a visuo-tactile virtual reality simulator and a randomized controlled trial protocol to determine the effectiveness of the simulator in training for minimally invasive caries removal. A three-dimensional, multilayered caries model was reconstructed from 10 micro-computed tomography (CT) images of deeply carious extracted human teeth before and after caries removal. The full grey scale 0-255 yielded a median grey scale value of 0-9, 10-18, 19-25, 26-52, and 53-80 regarding dental pulp, infected carious dentin, affected carious dentin, normal dentin, and normal enamel, respectively. The simulator was connected to two haptic devices for a handpiece and mouth mirror. The visuo-tactile feedback during the operation varied depending on the grey scale. Sixth-year dental students underwent a pretraining assessment of caries removal on extracted teeth. The students were then randomly assigned to train on either the simulator (n=16) or conventional extracted teeth (n=16) for 3 days, after which the assessment was repeated. The posttraining performance of caries removal improved compared with pretraining in both groups (Wilcoxon, p&lt;0.05). The equivalence test for proportional differences (two 1-sided t-tests) with a 0.2 margin confirmed that the participants in both groups had identical posttraining performance scores (95% CI=0.92, 1; p=0.00). In conclusion, training on the micro-CT multilayered caries model with the visuo-tactile virtual reality simulator and conventional extracted tooth had equivalent effects on improving performance of minimally invasive caries removal.
Hybrid coronary revascularization versus percutaneous strategies in left main stenosis: a propensity match study
Authors: Repossini Alberto , Di Bacco Lorenzo , Rosati Fabrizio , Tespili Maurizio , Saino Antonio , Ielasi Alfonso , Muneretto Claudio 
Published: March 2018

Aims
Hybrid revascularization (HCR) has been recently proposed as an alternative strategy in multivessel coronary disease, particularly in patients with high SYNTAX scores and risk scores. The objective of this study is to evaluate the outcomes of HCR versus percutaneous coronary intervention (PCI) drug-eluting stenting in left main treatment.

Methods
A series of 198 consecutive patients with left main stenosis have been treated. HCR, was performed in 77 patients (G1) whereas 121 patients (G2) received PCI on left main. An adjusted analysis using inverse probability weighting (IPW) was performed. Primary outcomes include: 30-day mortality, postoperative acute myocardial infarction, 18 months’ MACCEs: cardiac death, stroke, acute myocardial infarction (AMI), repeated target vessel revascularization (TVR).

Results
SYNTAX score was 29.5 ± 6.9 in G1 and 29.1 ± 6.5 in G2 (P = 0.529). In G2, three patients (2.7%) died because of cardiogenic shock; no deaths occurred in G1 (P = 0.603). No major complications were reported in G1 and there was no mortality at 18 months’ follow-up in both groups. Survival freedom from MACCEs at 18 months’ follow-up was significantly higher in G1 (G1: 93.3 ± 4.6% versus G2: 72.3 ± 6.3; P = 0.001) mostly because of the higher freedom from TVR (G1: 93.3 ± 4.6% versus G2: 75.5 ± 5.6; P = 0.002). At Cox regression analysis, PCI was an independent predictor of MACCEs and TVR (hazard ratio 3.9, CI 1.36–9.6; P = 0.027).

Conclusion
PCI in patients with left main and multivessel disease is a viable strategy, with a good outcome. HCR, demonstrated a lower incidence of cardiac adverse events such as AMI and TVR. Future comparative studies will be helpful to identify the optimal patient population for HCR.

Published: March 2018

The aim of this paper was to identify educational issues commonly used by politicalÂ parties or candidates for district head/head of state to gain community support the campaign asÂ education can serve as a medium of attraction in determining the direction of support andÂ affiliation to political parties/candidates of particular district head/state head. Data and informationÂ were collected by literature study and analyzed using descriptive qualitative approach. It isÂ concluded that political parties have tendency to raise simillar educational issues such asÂ implementing free education, improving quality of teachers and educators, and increasingÂ fascilities and educational budget. In some cases these issues are proven to be very effectiveÂ in maximizing community support Â egarding the process of determining the local leaders throughÂ the electoral process. What makes it so attractive in the political process is because education is considered as one of the essential parts of human basic needs which is a part of welfareÂ enhancement process.ABSTRAKÂ Tulisan ini untuk mengkaji isu pendidikan yang lazim digunakan partai politik atauÂ calon Kepala Daerah/Kepala Negara untuk menjaring dukungan masyarakat dalam kampanye.Â Isu-isu pendidikan dapat menjadi daya tarik masyarakat dalam menentukan dukungan danÂ arah afiliasi terhadap partai politik/calon Kepala Daerah/Kepala Negara tertentu. Data danÂ informasi diperoleh melalui studi literatur yang dianalisis secara kualitatif deskriptif.Â Kesimpulannya adalah bahwa isu pendidikan yang ditawarkan partai politik dalam kampanyeÂ memiliki kecenderungan yang sama antar partai politik/antar peserta kampanye, di antaranyaÂ terkait dengan penyelenggaraan pendidikan gratis, peningkatan mutu guru dan tenaga pendidik,Â pemenuhan sarana dan prasarana pendidikan serta peningkatan anggaran bidang pendidikan.Â Pada beberapa kasus terbukti bahwa isu tersebut berhasil memaksimalkan dukungan masyarakatÂ dalam proses penentuan pemimpin daerah melalui proses pemilihan umum. Daya tarik isuÂ pendidikan dalam proses politik disebabkan karena pendidikan dinilai sebagai salah satu bagianÂ penting dari kebutuhan dasar manusia yang merupakan bagian dari proses menuju peningkatanÂ kesejahteraan hidup.
Persoalan Pelestarian Bahasa Ciacia: Refleksi atas Etika Diskursus
Authors: Nurrochsya Mikka Wildha 
Published: March 2018

Ciacia language is the language used by the Ciacia community in SoutheastÂ Sulawesi. In August 2009, the Mayor of Baubau, Southeast Sulawesi, enacted policy toÂ adapt the Korean alphabet (Hangeul) into the Ciacian alphabet because the Ciacia languageÂ does not have its own script. This decision immediately caused controversy as some agreed and others disagreed. This paper has two objectives. First, it seeks to observe the diverse opinions surrounding the decision to adapt the Korean alphabet into the Ciacia alphabet. Secondly, the paper offers a reflection on the ethical discourse surrounding the adaptation of the Korean alphabet into the Ciacia alphabet. This study used case studies and took a qualitative approach. Results showed that there was not enough support given to the public to encourage practical discourse and offer a no-pressure environment. Support was neither given within the Ciacia community in Baubau nor outside Baubau to strengthen Ciacia language and culture. This study concluded that those who agree with the adaptationÂ are likely to understand it as serving an instrumental function in furthering economic and political interests. Meanwhile, those who oppose the adaptation are more concerned with culture preservation. Proper discourse has not taken place in regards to this issue. Thus, the debate continues to be unresolved.ABSTRAKÂ Bahasa Ciacia merupakan bahasa yang digunakan oleh masyarakat Ciacia di Sulawesi Tenggara. Walikota Baubau, Sulawesi Tenggara pada Agustus 2009 memutuskan kebijakan mengadaptasi aksara Korea (Hangeul) menjadi aksara Ciacia karena Bahasa Ciacia tidak mempunyai aksara sendiri. Keputusan ini menimbulkan reaksi baik pro maupun kontra. Tulisan ini mempunyai dua tujuan Pertama, ingin mengetahui pendapat-pendapat tentang kasus adaptasi aksara Korea menjadi aksara Ciacia. Kedua, ingin mengetahui implementasi etika diskursus untuk menyelesaikan kasus adaptasi aksara Korea menjadi aksara Ciacia. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus. Hasil penelitian menunjukan bahwa kasus adaptasi ini kurang memberikan ruang publik untuk diskursus praktis dalam suasana saling pengertian dan bebas dari tekanan, baik dalam masyarakat Ciacia di wilayah Kota Baubau maupun masyarakat Ciacia di luar Kota Baubau sebagai pendukung bahasa dan budaya masyarakat Ciacia. Penelitian ini menyimpulkan bahwa pihak yang pro adaptasi lebih cenderung berorientasi pada rasionalitas instrumental yakni kepentingan ekonomis dan politis, sedangkan pihak yang kontra berorientasi pada pelestarian budaya. Dalam kasus adaptasi ini belum diterapkan etika diskursus secara memadai sehingga tetap menjadi perdebatan yang tak terselesaikan.
Kinematic Differences During Single-Leg Step-Down Between Individuals With Femoroacetabular Impingement Syndrome and Individuals Without Hip Pain
Authors: Lewis Cara L. , Loverro Kari L. , Khuu Anne 
Published: March 2018

Study Design Controlled laboratory study, case-control design. Background Despite recognition that femoroacetabular impingement syndrome (FAIS) is a movement-related disorder, few studies have examined dynamic unilateral tasks in individuals with FAIS. Objectives To determine whether movements of the pelvis and lower extremities in individuals with FAIS differ from those in individuals without hip pain during a single-leg step-down, and to analyze kinematic differences between male and female participants within groups. Methods Individuals with FAIS and individuals without hip pain performed a single-leg step-down while kinematic data were collected. Kinematics were evaluated at 60° of knee flexion. A linear regression analysis assessed the main effects of group, sex, and side, and the interaction of sex by group. Results Twenty individuals with FAIS and 40 individuals without hip pain participated. Individuals with FAIS performed the step-down with greater hip flexion (4.9°; 95% confidence interval [CI]: 0.5°, 9.2°) and anterior pelvic tilt (4.1°; 95% CI: 0.9°, 7.3°) than individuals without hip pain. Across groups, female participants performed the task with more hip flexion (6.1°; 95% CI: 1.7°, 10.4°), hip adduction (4.8°; 95% CI: 2.2°, 7.4°), anterior pelvic tilt (5.8°; 95% CI: 2.6°, 9.0°), pelvic drop (1.4°; 95% CI: 0.3°, 2.5°), and thigh adduction (2.7°; 95% CI: 1.3°, 4.2°) than male participants. Conclusion The results of this study suggest that individuals with FAIS have alterations in pelvic motion during a dynamic unilateral task. The noted altered movement patterns in the FAIS group may contribute to the development of hip pain and may be due to impairments that are modifiable through rehabilitation.
