Published: March 2017

Background: To assess the prevalence of the symptoms and signs of temporomandibular disorders (TMDs) and determine the prevalence of TMDs among elderly Vietnamese aged 65–74 years old. Methods: A cross-sectional study was conducted among 258 participants aged 65–74 years old (128 females and 130 males) using two strategies for TMD diagnosis: a clinical examination of the temporomandibular joint and its associated structures using the Diagnostic Criteria for Temporomandibular Disorders Axis I; and a set of 14 questions regarding TMD symptoms to obtain anamnestic data. Results: The prevalence of TMD symptoms was: headache 49.6%; temporomandibular joint noise 28.0%; orofacial pain 25.2%; jaw locking 3.1%; 62.5% of participants had at least one TMD symptom. Headaches were more prevalent in females than males ( p=0.009) and rural than urban residents ( p<0.001). The most frequent signs were temporomandibular joint crepitus (50.4%), clicking (48.1%) and mouth-opening deviation (37.6%). Temporomandibular joint crepitus and mouth-opening deviation were more frequent among rural than urban ( p=0.024 and p<0.001, respectively). TMD was found in 56.6% of the total sample. Of the TMD sufferers, 37.6% were diagnosed with disc displacement, 34.9% with degenerative joint disease, 3.5% with myalgia and 1.2% with arthralgia. Conclusions: More than half of elderly Vietnamese have at least one TMD symptom. TMD sounds were the most common clinical sign of TMD. There were no differences between the genders or place of residence and TMD diagnosis. Disc displacement and degenerative joint disease were most prevalent among elderly Vietnamese.

Authors: Shenoy Vivek N. , Gifford Hanson S. , Kao John T. 
Published: March 2017

Background: Medial knee osteoarthritis (OA) typically occurs with excessive mechanical load within the medial compartment, resulting in degeneration of the articular cartilage. Purpose: A novel extracapsular implant (Latella Knee Implant) has been developed to unload the medial compartment of the knee. The implant displaces the iliotibial band (ITB) over the lateral femoral condyle, thereby increasing its effective moment arm, resulting in a transfer of load from the medial compartment to the lateral compartment of the knee. A cadaveric study was performed to evaluate the effect of altering the moment arm of the ITB on knee biomechanics. Study Design: Controlled laboratory study. Methods: A 6-degrees-of-freedom robotic testing system was utilized to measure medial and lateral compartment loads in 8 fresh-frozen cadaveric knees at various ITB loads and knee flexion angles. Measurements were made with and without the implant in place. The system measured the compartment forces at flexion angles between 0° and 30° under 3 simulated loading conditions (300 N quadriceps, 100 N hamstrings, and [1] 0 N ITB, [2] 50 N ITB, [3] 100 N ITB). Results: Lateral displacement of the ITB between 15 and 20 mm resulted in medial compartment unloading between 34% and 65%. Conclusion: Unloading the medial compartment with this novel implant has the potential to address the treatment gap for patients with medial knee OA. Clinical Relevance: Currently, there exists a treatment gap for patients with medial compartment OA who have exhausted conservative management but whose disease and symptoms do not warrant more invasive surgical procedures. An extracapsular implant to unload the medial compartment could fill this treatment gap by providing patients and surgeons with a less invasive option for early to mid-stage OA. Unloading the medial compartment may alleviate pain and improve function, allowing patients with early-stage medial OA to remain active longer prior to considering more invasive options such as arthroplasty.

Published: March 2017

BackgroundKetamine has recently become an agent of interest as an acute treatment for severe depression and as the anaesthetic for electroconvulsive therapy (ECT). Subanaesthetic doses result in an acute reduction in depression severity while evidence is equivocal for this antidepressant effect with anaesthetic or adjuvant doses. Recent systematic reviews call for high-quality evidence from further randomised controlled trials (RCTs).AimsTo establish if ketamine as the anaesthetic for ECT results in fewer ECT treatments, improvements in depression severity ratings and less memory impairment than the standard anaesthetic.MethodDouble-blind, parallel-design, RCT of intravenous ketamine (up to 2 mg/kg) with an active comparator, intravenous propofol (up to 2.5 mg/kg), as the anaesthetic for ECT in patients receiving ECT for major depression on an informal basis. (Trial registration: European Clinical Trials Database (EudraCT): 2011-000396-14 and clinicalTrials.gov: NCT01306760.)ResultsNo significant differences were found on any outcome measure during, at the end of or 1 month following the ECT course.ConclusionsKetamine as an anaesthetic does not enhance the efficacy of ECT.

BackgroundResearch suggests that lesbian, gay and bisexual (LGB) adolescents have a higher risk of suicidal behaviours than their heterosexual peers, but little is known about specific risk factors.AimsTo assess sexual orientation as a risk factor for suicidal behaviours, and to identify other risk factors among LGB adolescents and young adults.MethodA systematic search was made of six databases up to June 2015, including a grey literature search. Population-based longitudinal studies considering non-clinical populations aged 12–26 years and assessing being LGB as a risk factor for suicidal behaviour compared with being heterosexual, or evaluating risk factors for suicidal behaviour within LGB populations, were included. Random effect models were used in meta-analysis.ResultsSexual orientation was significantly associated with suicide attempts in adolescents and youths (OR=2.26, 95% CI 1.60–3.20). Gay or bisexual men were more likely to report suicide attempts compared with heterosexual men (OR=2.21, 95% CI 1.21–4.04). Based on two studies, a non-significant positive association was found between depression and suicide attempts in LGB groups.ConclusionsSexual orientation is associated with a higher risk of suicide attempt in young people. Further research is needed to assess completed suicide, and specific risk factors affecting the LGB population.

Block-modular gas compressor units (GCU) of a container type with an aircraft and ship gasturbine drive – a power source of vibration and noise pollution of environment.
Their basic inner sources – gas turbine engine and a centrifugal compressor. Besides, to power noise sources in the structure of GCU belong multiplier, an air cleaner of the air inlet system, an exhaust shaft, section walls of an engine and a compressor.
A gas turbine engine and a compressor define mainly a distant sound field and the rest of noise sources – near-in one.
A complex modernization of such plants may be carried out on the basis of the investigations of the level of vibrations and noise of all elements of such units.
With this purpose there were carried out inves-tigations of vibro-acoustic characteristics of GCU of GCU-16MG type with the capacity of 16 MW where as a drive of the centrifugal compressor of 370-18-1 NZL type serves a ship convertible engine of DG-90 type produced by “Zarya” Co.
Noise sources and vibrations of blade machines are studied, their vibro-acoustic characteristics are analyzed and methods for the decrease of vibro-acoustic activities of GCUs of such a type are offered.

The paper deals with the object identification in the picture based on a structural approach. The analysis of existing methods is presented and a new procedure of image identification with the use of a structural approach is shown.
In the introduction there is described a significance of picture decoding and a concept of a structure in the picture is designated.
The analysis of such a structural approach to image identification in a picture as a symbolic description which is a transition from the simplest signs of a picture to a set of graphic symbols. The second structural method analyzed in the paper is a syntactic approach to the image description. Here the whole picture is divided up to the simplest elements. The elementary graphic primitives are emphasized which make a pic-ture. And further the objects of the picture are de-scribed by a set of primitives. The regulation for the description of an object as a chain of primitives sets with the aid of the socalled language grammar of image description. Merits and demerits of existing structural methods are described, one of which is a complexity of object description on the picture of a real world. The offer on the necessity of the development of a new method taking into account the signs of really existing object and also describing objects in a formal view is put forward.
In the basic part a developed procedure defining objects in the picture as a specified polychromatic multitude emphasizing such properties as a significance of brightness, an object position and a number of additional characteristics is described. The definition of objects in the picture takes place by means of the creation of a structured description of known objects of the picture the identification on the basis of the use of a neuronet approach and a specification of the structure of objects found. As a result of the identification according to this procedure there is obtained a multitude of objects which was necessary to identify in the picture presented in a structural form. Such an approach can be used for various level of hierarchy at the description of objects in the picture it also allows taking into account not only brightness characteristics and a form, but a number of additional signs of objects.
In the conclusion the distinguishing features of this procedure and directions of its development are shown.

Authors: Дмитроченко Олег , Dmitrochenko Oleg 
Published: March 2017

The work purpose: a systematic (constant) clas-sification of finite elements for designation unity, the exclusion of repeated investigations and results dupli-cating.
Methods. A decimal nomenclature dncmkot code for finite elements is offered. It is based on the geometry and structure presentation of
node coordinates by integral (whole) parame-ters: d – dimensionality, n – nodes number, c – parameter defining a structure of node coordinates, for example, coordinates number in a node, m – number of interpolation polynomials of an element. For more complicated elements the application of additional parameters is possible. To this there are added of an element physical functional: k – order of senior derivative upon which depends a sub-integral expression of a physical functional, t – additional pa-rameter-type.
Results. There is offered an algorithm allowing calculating functions of an element form, its matrix of rigidity and others through dncmkot code. The corres-pondence of the finite elements set from ANSYS soft-ware to their codes according to the classification offered is shown. The examples of new elements creation on the basis of the classification offered are presented.
Conclusion: the classification offered allows describing unambiguously existing finite elements and also creating in an automated way new ones according to dncmkot code.
Stimulating Online Reviews by Combining Financial Incentives and Social Norms

Published: March 2017

In hopes of motivating consumers to provide larger volumes of useful reviews, many retailers offer financial incentives. Here, we explore an alternative approach, social norms. We inform individuals about the volume of reviews authored by peers. We test the effectiveness of using financial incentives, social norms, and a combination of both strategies in motivating consumers. In two randomized experiments, one in the field conducted in partnership with a large online clothing retailer based in China and a second on Amazon Mechanical Turk, we compare the effectiveness of each strategy in stimulating online reviews in larger numbers and of greater length. We find that financial incentives are more effective at inducing larger volumes of reviews, but the reviews that result are not particularly lengthy, whereas social norms have a greater effect on the length of reviews. Importantly, we show that the combination of financial incentives and social norms yields the greatest overall benefit by motivating reviews in greater numbers and of greater length. We further assess treatment-induced self-selection and sentiment bias by triangulating the experimental results with findings from an observational study.

Published: March 2017

AbstractTo identify similarities and differences in the behavioral profile of children with Williams syndrome from Spain (n = 53) and the United States (n = 145), we asked parents of 6- to 14-year-olds with Williams syndrome to complete the Child Behavior Checklist 6–18. The distribution of raw scores was significantly higher for the Spanish sample than the American sample for all of the higher-order factors and half of both the empirically based and Diagnostic and Statistical Manual of Mental Disorders (DSM)-oriented scales. In contrast, analyses based on country-specific T-scores indicated that the distribution for the Spanish sample was significantly higher than for the American sample only on the Social Problems scale. No gender differences were found. Genetic and cultural influences on children's behavior and cultural influences on parental ratings of behavior are discussed.
Impact of Attention Training on Academic Achievement, Executive Functioning, and Behavior: A Randomized Controlled Trial
Authors: Kirk Hannah , Gray Kylie , Ellis Kirsten , Taffe John , Cornish Kim 
Published: March 2017

AbstractChildren with intellectual and developmental disabilities (IDD) experience significant difficulties in attention, learning, executive functions, and behavioral regulation. Emerging evidence suggests that computerized cognitive training may remediate these impairments. In a double blind controlled trial, 76 children with IDD (4–11 years) were randomized to either an attention training (n = 38) or control program (n = 38). Both programs were completed at home over a 5-week period. Outcome measures assessed literacy, numeracy, executive functioning, and behavioral/emotional problems, and were conducted at baseline, post-training, and 3-month follow-up. No training effects were observed at post-training; however, children in the training group showed greater improvements in numeracy skills at the 3-month follow-up. These results suggest that attention training may be beneficial for children with IDD; however, the modest nature of the intervention effects indicate that caution should be taken when interpreting clinical significance.
Can a Memorial Communicate Embodied Trauma? Reenacting Civilian Bodies in the No Gun Ri Peace Park
Authors: Choi Suhi 
Published: March 2017

Abstract
In 2011, South Korea built an unusual memorial that honors civilian victims of an American atrocity during the Korean War. This memorial, called the No Gun Ri Peace Park, particularly commemorates the No Gun Ri killings, a 2000 Pulitzer Prize–winning story that depicts the massacre by American GIs of South Korean civilians who were taking refuge underneath a bridge called No Gun Ri. As a durable war mnemonic in a public site, the park is now performing the critical role that survivors and victims’ families used to carry: witnessing, performing, and transferring trauma to others. This essay critically looks at not only how the park reenacts civilian bodies in communicating a traumatic event that most visitors did not experience directly but also how it—as a newly constructed sign—negotiates meanings of the No Gun Ri bridge, the original site of the killings that is located adjacent to the park.
Transforming Violence into a Focusing Event: A Reception Study of the 1946 Georgia Lynching
Authors: Childers Jay P. 
Published: March 2017

Abstract
Scholars have repeatedly argued that Harry Truman’s decision to create the President’s Committee on Civil Rights would ultimately influence civil rights in the United States for many years afterward. However, scholars have been less clear in explaining what led Truman to act on civil rights in the first place. One important factor in the Truman administration’s creation of the committee that is often mentioned but almost never given as much attention as it deserves is the 1946 Georgia Lynching. Through a reception study of the articles, congressional debates, editorials, and speeches that responded to the murders, this essay argues that the murders of four African Americans in a small, rural town were transformed into a national focusing event because of how several key interpretive decisions emerged from the basic facts of the lynching in conjunction with larger cultural concerns. This analysis both highlights how the mass lynching came to have cultural significance and argues for the importance of rhetorical scholarship that engages the role of focusing events in both public debate and policy creation.
