PENINGKATAN KECERDASAN EKOLOGIS PESERTA DIDIK DALAM BERTRANSPORTASI HEMAT BBM MELALUI PEMBELAJARAN IPS KONTEKSTUAL (PTK di Kelas VII A SMP Negeri 2 Tomo Kabupaten Sumedang Pada Materi Kelangkaan Sumber Daya Alam)
Authors: Setiawati Tati 
Published: March 2018

Penelitian ini berawal dari kecemasan peneliti terhadap kondisi obyektif peserta didik di SMP Negeri 2 Tomo yang menggunakan sepeda motor sebagai alat transportasi ke sekolah. Mereka nampak belum menyadari dampak yang ditimbulkan dari penggunaan sepeda motor terhadap berbagai aspek, baik hukum, ekonomi, sosial, keselamatan dan juga terhadap penurunan kualitas lingkungan akibat konsumsi BBM dan polusi yang dihasilkan dari sisa pembakaran BBM. Selain itu dalam pembelajaran IPS, guru belum mengaitkan materi dengan permasalahan sosial dan lingkungan yang dihadapi peserta didik dalam kehidupan nyata. Oleh karena itu, melalui materi “Kelangkaan sumber daya alam” yang disisipkan dalam Standar Kompetensi 6 “Memahami kegiatan ekonomi masyarakat” silabus IPS Kelas VII semester dua KTSP, peneliti melakukan penelitian tindakan kelas sebagai bentuk perbaikan masalah lingkungan sekolah dan peningkatan kecerdasan ekologis peserta didik dalam bertransportasi hemat BBM melalui Pembelajaran IPS Kontekstual. Desain penelitian tindakan kelas yang digunakan adalah model PTK Elliot. Berdasarkan hasil penelitian tindakan kelas yang dilakukan sebanyak tiga siklus dengan dua belas kali pertemuan, diperoleh peningkatan kompetensi kecerdasan ekologis peserta didik, baik aspek pengetahuan, sikap maupun aspek keterampilan. Data awal pada siklus kesatu menunjukkan nilai kompetensi kecerdasan ekologis berada pada kategori “kurang” dan mengalami peningkatan pada siklus kedua menjadi kategori “cukup”, serta menjadi kategori “baik” pada siklus ketiga. Dengan demikian dapat disimpulkan bahwa pembelajaran IPS kontekstual secara efektif meningkatkan kecerdasan ekologis peserta didik dalam bertransportasi hemat BBM di kelas VII A SMP Negeri 2 dan dapat diterapkan di sekolah menengah pertama lainnya yang mempunyai karakteristik daerah serupa. Kata Kunci: Kecerdasan Ekologis, Transportasi Hemat BBM, Pembelajaran IPS Kontekstual.

Published: March 2018

The problem in this study is the low motivation to learn social science in students class VIII. Those are based on the observation that teachers have not applied varied learning models and tend to use conventional learning method. Learning activities have not actively involved students and many tudents feel bored in social science learning. Teachers need to overcome these problems by applying creative learning model, fun and can foster students&#39; learning motivation, one of them is cooperative learning model of make a match technique. This study aims to determine the effect of cooperative learning model of make a match technique to the motivation of social science learning in students class VIII SMP Negeri 40 Bandung. The design of this study uses Nonequivalent Control Group Design with quasi experimental research method. The samples of this study are 60 students and using 2 classes,namely class VIII D as experiment class and class VIII C as control class. Data were analyzed by using SPSS 17.00 for windows. The results showed that: First, the learning motivation of students before and after implementing cooperative learning model of make a match technique increased but still low category. Second, the students&#39; learning motivation before and after implementing conventional method did not increase. Third, simultaneously learning motivation between students who learn with cooperative learning model of make a match technique is better than students who learn with conventional learning method.

Stanley's Taste
Authors: Belfort Cerqueira Sebastião 
Published: March 2018

Stanley Cavell closes Contesting Tears with a chapter titled “Stella’s Taste: Reading Stella Dallas”, devoted to the 1937 movie, directed by King Vidor, which Cavell compares to the other movies he has studied in the book and finds “to be the most harrowing of the four melodramas to view again and again.” Cavell’s reading of this movie is organized against what he calls the generally “accepted view” of the film where there are two key interpretive moments: in one, Stella, the protagonist, on vacation with her teenage daughter, Laurel, at a fancy hotel, tries to impress Laurel’s new friends by dressing up and ends up making a fool of herself, in a spectacle of bad taste; Stella then finds out what people thought of her and realizes she has embarrassed Laurel, eventually deciding to drive her daughter away from her, towards her father (Stella’s now ex-husband); this takes us to the second key moment: the final scene, where Stella anonymously watches her daughter’s wedding from the sidewalk, through a window, and walks away, which is generally seen as confirming Stella’s sacrifice, representing the dissolution of motherhood — hence, of her identity.
Moral Perfectionism and Cavell's Romantic Turn
Authors: Kompridis Nikolas 
Published: March 2018

The first book of Stanley Cavell’s that I read is the only book that I ardently wished I had written, The Pursuits of Happiness: The Hollywood Comedy of Remarriage. Why this book, and not some high impact, world-historical book like Heidegger’s Being and Time or Wittgenstein’s Philosophical Investigations? Well, there are a number of reasons, some of them personal and some of them, well, Cavellian. Most immediately, the book explained to me why I so much enjoyed watching again and again over the course of more than three decades the films which are the objects of Cavell’s interpretations — why, in short, watching these films made me so happy, why they filled me with goofy delight, always ringing a smile to my face, a smile not unlike that smile of Cary Grant’s (from Holiday) reproduced in the pages of The Pursuits of Happiness.
Red Flags for Low Back Pain Are Not Always Really Red
Authors: Premkumar Ajay , Godfrey William , Gottschalk Michael B. , Boden Scott D. 
Published: March 2018

Background:
Low back pain has a high prevalence and morbidity, and is a source of substantial health-care spending. Numerous published guidelines support the use of so-called red flag questions to screen for serious pathology in patients with low back pain. This paper examines the effectiveness of red flag questions as a screening tool for patients presenting with low back pain to a multidisciplinary academic spine center.

Methods:
We conducted a retrospective review of the cases of 9,940 patients with a chief complaint of low back pain. The patients completed a questionnaire that included several red flag questions during their first physician visit. Diagnostic data for the same clinical episode were collected from medical records and were corroborated with imaging reports. Patients who were diagnosed as having a vertebral fracture, malignancy, infection, or cauda equina syndrome were classified as having a red flag diagnosis.

Results:
Specific individual red flags and combinations of red flags were associated with an increased probability of underlying serious spinal pathology, e.g., recent trauma and an age of >50 years were associated with vertebral fracture. The presence or absence of other red flags, such as night pain, was unrelated to any particular diagnosis. For instance, for patients with no recent history of infection and no fever, chills, or sweating, the presence of night pain was a false-positive finding for infection >96% of the time. In general, the absence of red flag responses did not meaningfully decrease the likelihood of a red flag diagnosis; 64% of patients with spinal malignancy had no associated red flags.

Conclusions:
While a positive response to a red flag question may indicate the presence of serious disease, a negative response to 1 or 2 red flag questions does not meaningfully decrease the likelihood of a red flag diagnosis. Clinicians should use caution when utilizing red flag questions as screening tools.

Authors: Marcano-Fernández F.A. , Balaguer-Castro Mariano , Fillat-Gomà F. , Ràfols-Perramon Ona , Torrens C. , Torner P. 
Published: March 2018

Background:
There are many different techniques for reducing acute anterior dislocations of the shoulder, and their use depends on surgeon preference. The objective of this study was to compare the pain experienced by a patient performing a self-reduction technique with the pain felt during a reduction performed by a trained physician.

Methods:
The study was carried out at the emergency department of a tertiary referral center. Patients between 18 and 60 years of age with an acute anterior shoulder dislocation were randomly allocated into 2 groups. In 1 group the emergency doctor actively guided the reduction process with the Spaso technique (Sp group), and in the other group the patient used the Boss-Holzach-Matter (also known as Davos or Aronen) self-reduction technique (BHM group). The pain experienced by the patient during the reduction was recorded by means of a visual analogue scale (VAS) ranging from 0 to 10. Other recorded data included demographic characteristics, reduction time, and success rate.

Results:
Of 378 patients assessed for eligibility from May 2015 until February 2017, 197 did not meet the inclusion criteria, 58 met exclusion criteria, 22 declined to participate, and 41 withdrew before randomization. Sixty acute anterior shoulder dislocations were randomized into the Sp group (n = 30) or the BHM group (n = 30). The BHM group experienced significantly less pain during reduction than the Sp group (p = 0.047), with mean pain scores of 3.57 (standard deviation [SD] = 2.1]) and 5.26 (SD = 2.9), respectively. No significant difference between groups was found with respect to reduction time (105 seconds [range, 10 to 660 seconds] in the Sp group and 90 seconds [range, 5 to 600 seconds] in the BHM group; p = 0.6) or success rate (67% and 77%, respectively; p = 0.39).

Conclusions:
The self-reduction technique results in less pain than, and is as efficient in achieving reduction of anterior shoulder dislocations as, the Spaso technique. These findings favor the use of the self-assisted method as an effective first-line treatment for shoulder dislocations seen in the emergency department as well as its use by patients with recurrent dislocation.

Mid-Term Results of Periacetabular Osteotomy for the Treatment of Hip Dysplasia Associated with Down Syndrome
Authors: Maranho Daniel A. , Williams Kathryn A. , Millis Michael B. , Kim Young-Jo , Novais Eduardo N. 
Published: March 2018

Background:
The treatment of hip dysplasia in patients with Down syndrome is challenging. We investigated the clinical, functional, and radiographic outcomes of periacetabular osteotomy (PAO) as well as factors associated with its failure at a minimum of 5 years of follow-up.

Methods:
Between 1992 and 2011, 19 patients with Down syndrome (26 hips) underwent PAO at a mean age of 16.2 ± 4.7 years. Hip pain and function were assessed with use of the modified Harris hip score (HHS) and the Gross Motor Function Classification System (GMFCS). The criteria for PAO failure were progression of osteoarthritis with a recommendation for total hip arthroplasty or hip arthrodesis, or an HHS of <60 points. Preoperative and most recent radiographs were assessed for measurement of the lateral and anterior center-edge angles, Tönnis angle, extrusion index, and anterior and posterior wall indices, and for evaluation of the Tönnis grade of osteoarthritis.

Results:
At an average follow-up of 13.1 ± 5.2 years (range, 5.4 to 24 years), 13 (62%) of 21 hips with an HHS demonstrated good or excellent HHS results (median, 91 points; interquartile range, 65 to 96 points). Ninety-five percent of the patients were independent in ambulation. All radiographic parameters significantly improved after PAO. Eight (31%) of the 26 hips were considered to have failed the procedure. Tönnis grade-2 osteoarthritis (4 hips compared with 1 hip; p = 0.008; odds ratio [OR] = 17.00) and older patient age at the time of the procedure (19.6 ± 6.7 compared with 14.7 ± 2.4 years; p = 0.017; OR = 1.36 per year) were demonstrated to be factors associated with PAO failure in an analysis of hips that failed compared with those without failure at the time of latest follow-up.

Conclusions:
PAO improves radiographic deformity and helps to preserve independent ambulation in patients with hip dysplasia and Down syndrome. Although nearly 70% of the hips were preserved at an average of 13 years postoperatively, 1 in 3 hips met the criteria for failure, which was associated with older age at the time of the procedure and a moderate osteoarthritis grade (Tönnis grade 2).

A Data-Analytics Tutorial: Building Predictive Models for Oil Production in an Unconventional Shale Reservoir
Authors: Schuetter Jared , Mishra Srikanta , Zhong Ming , LaFollette (ret.) Randy 
Published: March 2018

SummaryConsiderable amounts of data are being generated during the development and operation of unconventional reservoirs. Statistical methods that can provide data-driven insights into production performance are gaining in popularity. Unfortunately, the application of advanced statistical algorithms remains somewhat of a mystery to petroleum engineers and geoscientists. The objective of this paper is to provide some clarity to this issue, focusing on how to build robust predictive models and how to develop decision rules that help identify factors separating good wells from poor performers. The data for this study come from wells completed in the Wolfcamp Shale Formation in the Permian Basin. Data categories used in the study included well location and assorted metrics capturing various aspects of well architecture, well completion, stimulation, and production.Predictive models for the production metric of interest are built using simple regression and other advanced methods such as random forests (RFs), support-vector regression (SVR), gradient-boosting machine (GBM), and multidimensional Kriging. The data-fitting process involves splitting the data into a training set and a test set, building a regression model on the training set and validating it with the test set. Repeated application of a “cross-validation” procedure yields valuable information regarding the robustness of each regression-modeling approach. Furthermore, decision rules that can identify extreme behavior in production wells (i.e., top x% of the wells vs. bottom x%, as ranked by the production metric) are generated using the classification and regression-tree algorithm. The resulting decision tree (DT) provides useful insights regarding what variables (or combinations of variables) can drive production performance into such extreme categories.The main contributions of this paper are to provide guidelines on how to build robust predictive models, and to demonstrate the utility of DTs for identifying factors responsible for good vs. poor wells.

Authors: Yang Shuoye 
Published: March 2018

Background:
The therapeutic ability and application of antifungal peptide (APs) are limited
by their physico-chemical and biological properties, the nano-liposomal encapsulation would improve
the in vivo circulation and stability.
</P><P>
Objective: To develop a long-circulating liposomal delivery systems encapsulated APs-CGA-N12 with
PEGylated lipids and cholesterol, and investigated through in vivo pharmacokinetics.

Methods:
The liposomes were prepared and characterized, a rapid and simple liquid chromatographytandem
mass spectrometry (LC-MS/MS) assay was developed for the determination of antifungal peptide
in vivo, the pharmacokinetic characteristics of APs liposomes were evaluated in rats.

Results:
Liposomes had a large, unilamellar structure, particle size and Zeta potential ranged from 160
to 185 nm and -0.55 to 1.1 mV, respectively. The results indicated that the plasma concentration of
peptides in reference solutions rapidly declined after intravenous administration, whereas the
liposomeencapsulated ones showed slower elimination. The AUC(0-∞) was increased by 3.0-fold in
liposomes in comparison with standard solution (20 mg·kg-1), the half-life (T1/2) was 1.6- and 1.5-fold
higher compared to the reference groups of 20 and 40 mg·kg-1, respectively.

Conclusion:
Therefore, it could be concluded that liposomal encapsulation effectively improved the
bioavailability and pharmacokinetic property of antifungal peptides.
Degradation Prediction of Rail Tracks: A Review of the Existing Literature
Authors: Elkhoury Najwa , Hitihamillage Lalith , Moridpour Sara , Robert Dilan 
Published: March 2018

In the past few decades, the railway infrastructure has been widely expanded in urban and rural areas, making it the most complex matrix of rail transport networks. Safe and comfortable travel on railways has always been a common goal for transportation engineers and researchers, and requires railways in excellent condition and well-organized maintenance practices. Degradation of rail tracks is a main concern for railway organizations as it affects the railway’s behaviour and its parameters, such as track geometry, speed, traffic and loads. Therefore, the prediction of the degradation of rail tracks is very important in order to optimise maintenance needs, reduce maintenance and operational costs of railways, and improve rail track conditions.This paper provides a comprehensive review of rail degradation prediction models, their parameters, and the strengths and weaknesses of each model. A comprehensive discussion of existing research and a comparison of different models of degradation of rail tracks is also provided. Finally, this review presents concluding remarks on the limitations of existing studies and provides recommendations for further research and appraisal practices.
Diffusion Theory for the Infection Pathway of Virus in a Living Cell
Authors: Itto Yuichi 
Published: March 2018

Background:
The infection pathway of virus in living cell is of interest from the viewpoint of the physics of diffusion.

Objective:
Here, recent developments about a diffusion theory for the infection pathway of an adeno-associated virus in cytoplasm of a living HeLa cell are reported.

Theories and Results:
Generalizing fractional kinetics successfully modeling anomalous diffusion, a theory for describing the infection pathway of the virus over the cytoplasm is presented. The statistical property of the fluctuations of the anomalous-diffusion exponent is also discussed based on a maximum-entropy-principle approach. In addition, an issue regarding the continuum limit of the entropy introduced in the approach is carefully examined. The theory is found to imply that the motion of the virus may obey a scaling law.
