Dinding merupakan salah satu elemen non-struktur yang terdapat dalam suatu bangunan gedung yang berfungsi sebagai penyetabil, pengikat balok dan kolom-kolom. Manfaat lain dari dinding adalah sebagai penyekat ruangan dan pelindung dari pengaruh alam (iklim dan cuaca)(Pradipta, 2010).Saat ini material-material penyusun dinding semakin beragam, diantaranya yaitu penggunaan batako, kayu, bambu, multiplek, bata ringan, dan panel precast. Berbagai macam material tersebut bersaing dalam merebut konsumennya, sehingga muncul beberapa merk dengan spesifikasi yang beragam. Hal ini semata-mata bertujuan agar dapat dihasilkan bangunan yang lebih baik dengan biaya, mutu, dan waktu yang memadai untuk dinding. Dahulu orang cenderung menggunakan batako ataupun batu bata, namun saat ini orang sudah banyak yang menggunakan bata ringan sebagai penyusun dinding. Selain dinding bata ringan, terdapat dinding panel precast.
An Isoelastic Monoblock Cup Retains More Acetabular and Femoral Bone Than a Modular Press-Fit Cup
Authors: Brodt Steffen , Jacob Benjamin , Nowack Dimitri , Zippelius Timo , Strube Patrick , Matziolis Georg 
Published: February 2021

Background:
For cup revision after total hip arthroplasty, sufficiently good periacetabular bone stock is a prerequisite for fixation of the revision implant. Cementless cups can lead to a relevant reduction of peri-implant bone mineral density (BMD) through stress-shielding.

Methods:
Fifty patients were included in this prospective randomized controlled trial. Group 1 (RM group) received an isoelastic monoblock cup (RM Pressfit vitamys; Mathys). Group 2 (IT group) received a modular titanium cup (Allofit-S IT Alloclassic with a polyethylene liner; Zimmer). Periacetabular BMD was determined and subdivided into 4 regions of interest by dual x-ray absorptiometry at 1 week (baseline) and at 4 years postoperatively. Our primary outcome was reduction in periacetabular BMD.

Results:
Periacetabular BMD was reduced by an average of 15.1% in the RM group and 16.5% in the IT group at 4 years postoperatively. No significant difference was found between the 2 groups over the periacetabular structure as a whole. However, the decrease of BMD in the polar region was significantly different in the RM group (4.9% ± 10.0%) compared with the IT group (15.9% ± 14.9%, p = 0.005). Use of the isoelastic RM cup showed significantly less bone loss than the modular IT cup.

Conclusions:
Relevant loss of BMD at 4 years after surgery was identified in the periacetabular region in both groups. No differences between the 2 cup systems were found when looking at the overall periacetabular region. As a secondary outcome, less postoperative periacetabular bone loss occurred in the polar region when an isoelastic cup was used. Longer follow-up is required to allow for conclusions to be drawn about the long-term course of the 2 cup systems.

Development of a Short Form of the Negative Pain Thoughts Questionnaire (NPTQ)
Authors: Dekker Anne-Britt , Teunis Teun , Schipper Inger , Ring David 
Published: February 2021

Background:
Thoughts affect pain intensity and the magnitude of activity intolerance for a given nociception. The Negative Pain Thoughts Questionnaire (NPTQ) measures common unhelpful cognitive biases regarding pain. A shorter version of the NPTQ could be used in daily practice to improve health by identifying important misconceptions.

Methods:
One hundred and thirty-seven patients seeking specialty musculoskeletal care completed questionnaires addressing demographics, negative pain thoughts, worst-case thinking, resiliency, the magnitude of self-reported activity intolerance, and pain intensity. Patients were randomly allocated to a learning cohort (110 patients, 80%) and a validation cohort (27 patients, 20%). Based on factor analysis of the learning cohort, 4 questions were selected to create the NPTQ short form (NPTQ-SF). Floor and ceiling effects of the NPTQ and NPTQ-SF were analyzed. Psychometric properties of the NPTQ-SF were tested with use of Spearman correlations with the NPTQ. The internal consistency of the NPTQ and NPTQ-SF was analyzed with use of the Cronbach α coefficient. To test external validity, we calculated Spearman correlations with pain intensity, activity intolerance, the Pain Catastrophizing Scale, and the Brief Resiliency Scale in the validation cohort.

Results:
The Cronbach α was 0.90 for the NPTQ and 0.85 for the NPTQ-SF. The Spearman correlation between NPTQ and NPTQ-SF scores was 0.91 in the learning cohort and 0.93 in the validation cohort. In the validation cohort, there was no difference in the strength of the correlations of the NPTQ and NPTQ-SF with other questionnaires.

Conclusions:
These findings support the use of a brief, 4-question measure of unhelpful cognitive biases regarding pain in both research and patient care. The NPTQ-SF would benefit from external validation in an independent cohort.

Clinical Relevance:
The notable influence of common misconceptions (i.e., cognitive bias) on musculoskeletal symptoms can be measured with a brief questionnaire and used as a point of discussion with patients.

Published: February 2021

Background:
The transition to the new ICD-10 (International Classification of Diseases, Tenth Revision) coding system in the U.S. poses challenges to the ability to consistently and accurately measure trends in comorbidities and complications. We examined the prevalence of comorbidities and postoperative medical complications before and after the transition from ICD-9 to ICD-10 among patients who underwent primary total hip or knee arthroplasty (THA or TKA). We hypothesized that the transition to ICD-10 codes was associated with discontinuity and slope change in comorbidities and medical complications.

Methods:
The Elixhauser comorbidities and medical complications were identified using the Premier Healthcare database from fiscal year (FY)2011 to FY2018. Using multivariable segmented regression models, we examined the changes in the levels and slopes after the transition from ICD-9 to ICD-10 coding. Odds ratios (ORs) of <1 and >1 indicate decreases and increases, respectively, in levels and slopes.

Results:
Overall, 2,006,581 patients who underwent primary THA or TKA were identified. The mean age was 65.9 ± 10.5 years, and the median length of the hospital stay was 2 days (interquartile range [IQR], 2 to 3 days). Of the comorbidities studied, congestive heart failure, hypertension, and obesity had a statistically significant but clinically small discontinuity after the transition from ICD-9 to ICD-10 coding. Of the complications, pneumonia (OR = 0.66, 95% confidence interval [CI] = 0.48 to 0.90), acute respiratory failure (OR = 1.88, 95% CI = 1.52 to 2.33), sepsis (OR = 2.54, 95% CI = 1.45 to 4.44), and urinary tract infection (OR = 1.79, 95% CI = 1.32 to 2.42) demonstrated statistically significant discontinuity. Alcohol abuse and paralysis had an increasing prevalence before the ICD transition, followed by a decreasing prevalence after the transition. In contrast, metastatic cancer, weight loss, and acquired immunodeficiency syndrome (AIDS) showed a decreasing prevalence before the ICD transition followed by an increasing prevalence after the transition. Generally, complications showed a decreasing prevalence over time.

Conclusions:
The discontinuities after the transition from ICD-9 to ICD-10 coding were relatively small for most comorbidities. Medical complications generally showed a decreasing trend over the quarters studied. These findings support caution when conducting joint replacement studies that rely on ICD coding and include the ICD coding transition period.

Published: February 2021

Case:
A 29-year-old man sustained a near-complete laceration to the left pectoralis major muscle belly. The muscle and epimysium were repaired using the Kragh technique—a combination of running interlocked and Mason-Allen stitches. At the 6-year follow-up, the patient had an excellent outcome as measured by clinical scores (Short Form Survey-36, Disabilities of the Arm, Shoulder, and Hand, and American Shoulder and Elbow Surgeons Score), bench press, cosmesis, and magnetic resonance imaging.

Conclusions:
Acute traumatic open pectoralis muscle belly tears may be successfully repaired in select patients using the Kragh technique with excellent postoperative function and cosmesis.

Published: February 2021

Indonesia is one country that has a high risk of natural disasters. Ranked in 36 out of 172 countries in disaster index and having 2,372 disaster incidents in 2017, actions need to be taken to minimize the impact of natural disasters. One of it is to do a hazard map modeling. In making hazard maps, several approaches can be used, one of which is the semantic approach to extract disaster information. Therefore, this study aims to develop a system that can be used to extract spatiotemporal and semantic information related to natural disasters in Indonesia. This study uses the NLP method in conducting the information extraction process and carried out using the GATE (General Architecture for Text Engineering) application. In processing Indonesian language articles, it is necessary to develop the plugin because the Indonesian information structure is different from the default information structure in GATE application. The plugin development process is done by using ontology as the basis for determining semantic information. Literature study was carried out related to government regulations that further explained the need for semantic and spatiotemporal information about disaster events. system performance developed produces a precision value of 38% and a recall value of 32%. this is because the system experiences some difficulties in carrying out the information inference process. The reason for low precision rate is because the rules used in the inference process to pair the three types of information still cannot accommodate the variation of information positions in different sentences.
Investigating the Effects of Subjective Norms and Trialability on English Teachers` Attitude toward the Use of Technology
Authors: Davoodi Somaye , Akbarpour Leila , Hadipour Ehsan 
Published: February 2021

Despite the availability of many technological resources in academic settings and their determinant effect in the improvement of teaching and learning, it seems that teachers rarely used them. The aim of the present study is to investigate the effect of psychological variables on teachers` attitudes regarding technology use. In this research, most applicable models like the 'technology acceptance model', 'theory of reasoned action', and 'innovation diffusion theory' are used as the foundation for developing a conceptual framework. Variables such as 'perceived usefulness', 'perceived ease of use', 'trialability', 'subjective norms', and 'attitude' are recaptured from these models. The participants of the present research are high school English language teachers in Shiraz. The researcher uses stratified sampling to identify a representative sample from the population. The present study is administered by using five questionnaires to assess variables. The data are analyzed by means of path analysis. According to the obtained result, perceived ease of use is found to be affected by subjective norms and trialability, which in turn influenced the attitude of teachers toward using technology in their teachings. The results propose that the most influential factor on attitude is trialability (β= 0.38). On the other hand, perceived usefulness has a significant, influential effect on attitude. Subjective norms has an indirect but important effect on attitude.
On the runoff validation of ‘Global BROOK90’ automatic modeling framework
Authors: Vorobevskii Ivan , Kronenberg Rico , Bernhofer Christian 
Published: February 2021

Abstract
The recently presented Global BROOK90 automatic modeling framework combines a non-calibrated lumped hydrological model with ERA5 reanalysis data as the main driver, as well as with global elevation, land cover and soil datasets. The focus is to simulate the water fluxes within the soil–water–plant system of a single plot or of a small catchment especially in data-scarce regions. The comparison to runoff is an obvious choice for the validation of this approach. Thus, we choose for validation 190 small catchments (with a median size of 64 km2) with discharge observations available within a time period of 1979–2020 and located all over the globe. They represent a wide range of relief, land cover and soil types within all climate zones. The simulation performance was analyzed with standard skill-score criteria: Nash–Sutcliffe Efficiency, Kling–Gupta Efficiency, Kling–Gupta Efficiency Skill Score and Mean Absolute Error. Overall, the framework performed well (better than mean flow prediction) in more than 75% of the cases (KGESS &gt; 0) and significantly better on a monthly rather than on a daily scale. Furthermore, it was found that Global BROOK90 outperforms GloFAS-ERA5 discharge reanalysis. Additionally, cluster analysis revealed that some of the catchment characteristics have a significant influence on the framework performance.

Non-Combustion ⁴He Powered Propulsion
Authors: Bolivar Nelson Enrique , Vasilev Ivaylo T. 
Published: February 2021

One of the biggest hurdles nowadays rocket propulsion is the large use of fuel. The amount of fuel and the burning efficiency defines how long the rocket engine can work which intimately limits the range and the load capacity of the rockets and spaceships. This according to the Newton third law is unavoidable - in order to move forward you need to leave something behind. There have been several attempts in the past to create an engine which doesn't use fuel in the common sense, like the M drive, but so far all of them were unsuccessful. In this article we attempt to explore a novel principle, a recycling cycle of fuel, by optimizing parametrically a system that uses ⁴He phase transition.
