Published: September 2020

Kelompok Penjahit Gang Opek adalah kumpulan beberapa penjahit keliling yang mereparasi celana dan masih tersisa belakangan ini. Sebuah isu kompetisi pasar jahitan di daerah produksi pakaian menyebabkan berkurangnya order. Masalahnya, mereka perlahan berganti profesi, atau mencoba menerima order lain untuk menyambung hidup. Jenis pekerjaan yang kerap mereka terima adalah reparasi pantalon. Pantalon adalah istilah pakaian yang merujuk pada sebuah jenis celana yang panjangnya semata kaki. Namun demikian, permintaan pasar kian kompleks, jenis pekerjaan yang mereka kerjakan kian menyusut. Temuannya, penjahit keliling mengalami kesulitan membuat pantalon dengan design baru karena hanya terbiasa untuk memperbaiki. Untuk mengatasi masalah tersebut, sebuah pelatihan pantalon dengan menekankan pada pola, struktur dan volume menawarkan  pengembangkan cara berpikir meruang. Hal ini sekaligus mempertanyakan cara berpikir dalam perancangan pakaian yang kerap mengklaim penggunaan ilmu arsitektur sebagai inspirasi saja. Maka dari itu, cara berpikir meruang diterjemahkan melalui pengembangan metode twisting untuk menghasilkan volume pantalon yang dapat dikembangkan untuk menghasilkan perspektif keruangan melalui pecah pola dan penggunaan detail berbeda: misalnya pola – pola rok, sarung, kargo, celana pendek, atau apron . Pola pantalon pada kesempatan ini dikombinasikan untuk menghasilkan kebaruan berupa volume dan kegunaan pantalon untuk keruangan berbeda, sehingga dapat digunakan untuk aktivitas berbeda pula. Teknik twisting  pola pantalon jenis pensil dikombinasikan dengan pattern making software berbasis cad, dan dikembangkan sketsanya pada powerpoint presentation. Hasilnya akan menjadi pantalon contoh yang menjadi sebuah kritik atas stagnansi rancangan pantalon di Indonesia.

Image Watermarking Using All Phase Discrete Cosine Biorthogonal Transform in Selected Pixel Blocks
Authors: Khalifa Farhad M. , Saeed Mohammed G.
Published: September 2020

In the past decade, a transform called all phase discrete cosine biorthogonal transform (APDCBT) appeared in the field of digital image processing. It is mainly used to solve the negativity found in discrete cosine transform (DCT), especially in a low bit rate. In this paper, the APDCBT is employed for watermark insertion based on selected regions of an image. The insertion is depending on the homogeneity of each part of the image. To determine the extent of homogeneity, there are two criteria: Mean and standard deviation are applied for the intensity of the image. Medium frequency bands of APDCBT in image pixel blocks are used to hold the embedded watermark. Then, the transform is inversed to obtain the resultant watermarked image. The robustness of APDCBT against watermark removal attacks is tested and the experimental results showed the superiority of the APDCBT over traditional DCT in the watermark embedding system. More specifically, when the LSB reset attack applied. For instance, when the contrast adjustment attack applied, the average of normalized cross-correlation (NCC) values of extracted watermark images with the original watermark, it was 0.992 for the proposed method. This is a promised result, if it is compared with the NCC of the DCT method, which was 0.423. The proposed method can be used for copyright protection purpose.

Authors: Mirza Rebin A.
Published: September 2020

This research was conducted to evaluate the effect of probiotic supplementation on growth performance, gut microbiota, and hematology of local quails. Ninety-one-week-old quails were randomly distributed into three dietary treatments with three replicate per each for 42 days. The dietary treatments were: Treatment 1 which was control (no additive), standard diet added with Lactobacillus animalis bacteria 1 g/kg 1.35 × 109 colony forming units (CFU)/kg (PRO1) and commercial multi-strain probiotic (Lactobacillus acidophilus 2.75 × 1010 CFU, Streptococcus faecium 8.25 × 1010 CFU, and Bacillus subtilis 1.1 × 1010 CFU) (PRO2). Results showed that PRO1, isolated from chicken caeca, had probiotic properties to improve growth performance of local quail compared to the control group. In cecum digesta, addition of both types of probiotics significantly increased the number of Lactobacillus spp. and reduced the number of coliform bacteria at the end of the experiment. Furthermore, supplementation of both types of probiotics significantly increased the number of lymphocyte and reduced H/L ratio compared to the control group at the end of the experiment. While, no significant differences were observed between both types of probiotic. This research has established that L. animalis, which isolated in cecum of chicken origin, had the same data recorded when compared to commercial multi-strain bacteria probiotic by improved growth performance, gut microbiota, and hematology parameters and could be a convenient probiotic additive in dietary local quail.

Authors: Nogueira Ricardo Malcata , Cardoso Luis Santos , Fonseca Lino , Correia Miguel , Iraneta Amets , Roque Pedro , Matos Mario , Mafra Manuela
Published: September 2020

Background:

Cavernous malformations prevalence ranges from 0.4 to 0.6% and accounts for 5–15% of all central nervous system vascular malformations. Pineal cavernomas constitute <1% of all locations published in the literature, with a total of 26 cases reported, only 5 regarding the pediatric population until 2020. Overall annual hemorrhage rate is 2.4%. Symptoms are often due to hydrocephalus and intracranial hypertension.

Case Description:

We report a case of a 5-year-old child with visual disturbances, headache, and progressive neurologic deterioration. MR showed a lesion in the pineal region and triventricular hydrocephalus. She was submitted to endoscopic third ventriculostomy and total excision of the lesion by the infratentorial supracerebellar approach a few days later. Histopathological examination confirmed a pineal cavernous malformation. The patient returned to her normal life without any neurologic deficit and a normal development.

Conclusion:

The ideal treatment is primary lesion removal; however, due to the infrequency and because it is a curable lesion, studies seeking to deepen the knowledge of this disease are considered relevant.
A rare complication of ventriculoperitoneal shunt: Pleural effusion without intrathoracic ventriculoperitoneal shunt catheter
Authors: Hilmani Said , Mesbahi Tarek , Bouaggad Abderrahman , Lakhdar Abdelhakim
Published: September 2020

Background:

Symptomatic pleural effusion following ventriculoperitoneal shunt (VPS) insertion is very rare and poorly understood in the literature in contrary to other mechanical complications.

Case Description:

We report a case of 15 month-year-old girl who had VP shunt for congenital hydrocephalus. Twelve months after surgery, she was diagnosed with massive hydrothorax. Chest X-ray and thoracoabdominal CT scan confirmed the right pleurisy and showed the tip of the peritoneal catheter in the general peritoneal cavity. We made thoracic drainage of the transudative pleural effusion. When we released the chest tube, 24 h after, the girl showed a respiratory distress again and the effusion resumed at the X-ray control. Her symptoms abated after the realization of a ventriculoatrial shunt “VAS.” Repeat chest X-ray confirmed the resolution of the hydrothorax.

Conclusion:

Despite the not yet well-understood mechanism of this rare and important VPS complication, management is simple based on X-ray confirmation, thoracentesis with biological analysis, and catheter replacement, especially in atrium “VAS.”
Photoswitching, Umpolung and Reversible Self-Assembly of Gold Nanoparticles Covered With Thiolated Donor-Acceptor Stenhouse Adducts
Authors: sobczak grzegorz , Misztalewska-Turkowicz Iwona , Sashuk Volodymyr
Published: September 2020

The possibility of incorporating functional groups into molecular photoswitches is a prerequisite for their versatility and broad-range applications. Herein we present the first successful synthesis of DASA chromophores featuring a thiol group. The latter provides a unique opportunity to investigate the photoswitching behavior of these visible-light operating chromophores on the surface of metallic nanoparticles. This behavior can be modulated by irradiation time, solvent composition, DASAs population, and the organic layer underneath the chromophores. Moreover, the changes in polarity induced by DASAs photoisomerization are translated onto the colloidal particles giving rise to unusual interfacial and bulk-phase phenomena, including nonlinear solubility effects and reversible agglomeration that takes place in a time-controllable fashion. These findings pave the way for the rational design of new photoresponsive and smart materials.

Published: September 2020

Dalam proses penentuan mutu atau tingkat kemanisan buah mangga cengkir di pasaran pada umumnya dilakukan dengan dengan dua cara yaitu menggunakan pakar-pakar untuk pemilihan / sortasi kemanisan mangga atau menggunakan metode destruktif dengan cara pengambilan sampel, uji coba kemanisan mangga tersebut seperti menggunakan Refractometer. Permasalahan yang terjadi pada kedua proses tersebut yaitu memiliki cost yang relative besar dan tidak menghasilkan mutu yang seragam karena sortasi tingkat kemanisan mangga oleh pakar bersifat subjektif dan kemungkinan terjadinya kesalahan pengamatan sangat. Support Vector Machine (SVM) diimplementasikan pada penelitian ini dan K-Nearest Neighbour (K-NN) sebagai metoda pembanding untuk klasifikasi citra warna buah mangga cengkir. Dalam penelitan ini perbandingan antara kedua metode tersebut dibandingkan dengan hasil output dari alat pengukur tingkat kemanisan yaitu refractometer sebanyak 24 objek pengujian dengan akurasi sebesar 83,3%. Sedangkan hasil yang diperoleh dari metode K-NN dengan k=7 adalah data valid 21 buah dari 24 buah, dan data tidak valid 3 buah dari 24 buah.

Published: September 2020

Background: Multiple sclerosis (MS) is a demyelinating autoimmune disease characterized by the infiltration of T cells into the central nervous system. Polyamines, which contribute to cell proliferation, hypertrophy and tissue development, have some tissue-specific roles in brain tissue. So, we aimed in this study to present the possible effects of polyamines on MS.

Method: Thirty- five patients with MS and 35 sex and age-matched control were included in this study. Arginine decarboxylase (ADC), ornithine decarboxylase (ODC) and agmatinase levels were measured by ELISA kits.

Results: The patient group had higher ODC and agmatinase levels than controls. The correlation analyses between ODC, ADC, and agmatinase levels and disease duration were revealed that there was a negligible positive relationship between disease duration and agmatinase, with negligible negative relationship between disease duration and ODC and ADC. Additionally, there were showed respectively moderate and weak positive correlations between EDSS (Expanded Disability Status Scale) scores and newly developed lesions and ODC and agmatinase levels.

Conclusions: Elevated polyamine synthesis in MS patients was presented by detecting increased ODC, ADC and agmatinase levels compared to controls. Besides this increased polyamine synthesis in MS patients was also related with disease duration, number of newly developed lesions and disability.

Published: September 2020

In this research, we investigate the nonlinear vibration of functionally graded carbon nanotubes (FG-CNTs) for simply supported sandwich cylindrical panels. The sandwich consisting of three layers formed of (FG-CNTs) and isotropic material as (CNT, ALMINUME, CNT).  Mechanical properties of the sandwich media are acquired according to a reﬁned rule of blend approach. The governing equations were derived using a first-order deformation theory (FOSDT). Four kinds of carbon nanotubes of sandwich cylindrical panels were analyzed. The volume fraction of CNTs is varied. The properties of nonlinear responses and free vibration are studied. The numerical approach employs the fourth-order Runge-Kutta and Galerkine procedure. Which conducted for the dynamic analysis of the panels to present the natural frequencies and non-linear dynamic response expression. The results show that; the natural frequencies and the nonlinear vibration amplitude decrease with the volume fraction and thickness ratio increase. The nonlinear vibration amplitude response increases when increasing the excitation force. The initial imperfection and the elastic foundation have a minor impact on the nonlinear vibration response of the panel. The Pasternak Foundation has a larger impact than the Winkler foundation. The structure formed of FG-CNT present an excellent choice for high-performance of engineering applications.

Increasing the Performance of the Iterative Computed Tomography Image Reconstruction Algorithms
Authors: Khazal Shimaa Abdulsalam , Ali Mohammed Hussein
Published: September 2020

Computed tomography (CT) imaging is an important diagnostic tool. CT imaging facilitates the internal rendering of a scanned object by measuring the attenuation of beams of X-ray radiation. CT employs a mathematical technique of image reconstruction; those techniques are classified as; analytical and iterative. The iterative reconstruction (IR) methods have been proven to be superior over the analytical methods, but due to their prolonged reconstruction time, those methods are excluded from routine use in clinical applications. In this paper the reconstruction time of an IR algorithm is minimized through the employment of an adaptive region growing segmentation method that focuses the image reconstruction process on a specified region, thus ignoring unwanted pixels that increase the computation time. This method is tested on the iterative algebraic reconstruction technique (ART) algorithm. Some phantom images are used in this paper to demonstrate the effects of the segmentation process. The simulation results are executed using MATLAB (version R2018b) programming language, and a computer system with the following specifications: CPU core i7 (2.40 GHz) for processing. Simulation results indicate that this method will reduce the reconstruction time of the iterative algorithms, and will enhance the quality of the reconstructed image.

Published: September 2020

Kelebihan motor DC adalah mudahnya untuk dikendalikan kecepatan putarnya namun harus tetap maintenance untuk menjaga performanya. Dari kelebihan tersebut timbul suatu masalah dimana banyak yang menginginkan agar motor DC dapat berputar dengan kecepatan stabil. Oleh karena itu dibuatlah suatu alat yang mengatur kecepatan motor DC dengan menggunakan sistem logika Fuzzy dengan setting-point pada LabVIEW. Logika Fuzzy sendiri merupakan pengendali yang terbilang efektif karena memiliki respon sistem yang stabil dan tidak perlu mencari model matematisnya. Input Fuzzy dirancang dengan 2 masukan yaitu error dan delta error. Input Fuzzy akan diproses oleh NI USB 6008 dengan menggunakan program LabVIEW kemudian menghasilkan sinyal PWM sebagai pengontrol kecepatan motor. Proses Fuzzy logic menggunakan metode defuzzifikasi COA (Center Of Area) non-singleton. Pada pengendalian motor DC Fuzzy pada labVIEW dapat digunakan sebagai pengontrol motor dengan kecepatan stabil. Meskipun dengan nilai setpoint yang diubah namun kecepatan tetap terjaga kestabilannya. Berdasarkan hasil percobaan yang telah dilakukan dengan memasukan set point pada  kecepatan 0-3000 dengan rentan masing-masing 250 rpm, hasil keakurasian output menghasilkan error tertinggi yaitu ±118.928 pada setting point 1000 rpm dan error terendah yaitu ±2.9101 pada setting point 2500 rpm.

The study of ecological indicators, defining and establishing the means of measuring the health of the environment, is of great importance. The most important elements of ecosystems are the biological components, and environmental impact assessment of ecosystems will therefore require that these components are seriously laid out. It is, for example, not sufficient to assess the water quality by the use of physicochemical parameters, although their determination can be carried out much more rapidly. There exists, in general, a relation between species composition and water quality. It is well known that mussels are extensively utilized as a biological indicator of pollution of both marine and freshwater ecosystems. The reason is that the mussel is a sessile, filter-feeding, and able to accumulate within its tissues many of the contaminants. In addition, mussels show a wide geographical distribution as they permit the survey of extensive coastal and inland areas. The contaminants accumulated in the tissues of mussels may cause a “stress syndrome” with alteration to their physiology. On the other hand, global warming does affect the pH level, especially the marine water resulting increase in acidity. This can be the outcome of the existing genetic variation in natural populations of mussels. They because allow themselves to adapt to declining pH levels in the aquatic ecosystem caused by carbon emissions. We, therefore, focus on the factors that possibly effect the mussel biodiversity in aquatic ecosystems in relation to climate change as well as pollution concerned.

İŞÇİLERİN SAHİP OLDUĞU İZİN HAKLARININ 4857 İŞ KANUNU BAKIMINDAN DEĞERLENDİRİLMESİ
Authors: BAYSAL Mustafa
Published: September 2020

4857 sayılı İş Kanunu’na tabi işçilerin sahip olduğu önemli haklardan birisi de izin hakkıdır. Ancak izin hakkı tek başına bir anlam ifade etmez ve alt türlerine göre incelenmesi gerekir. Çünkü 4857 sayılı İş Kanunu’nda tek bir izin türü belirlenmemiş, bunun yerine farklı amaç-larla kullanılabilecek farklı izin türleri oluşturulmuştur. Yıllık ücretli izin, ücretsiz izin, maze-ret izni ya da diğer izinler şeklinde sınıflandırılabilecek izin hakkı; işçinin en temel anayasal haklarından da birisidir. İşçinin izin haklarını tam ve doğru şekilde kullanması; onun daha verimli olması, iş kazası riskinden daha uzak olması ve işverenin de hukuki sorumluluklarını yerine getirmesi anlamına gelir. Doğru ve efektif uygulama için ise izne dair tüm kuralların detaylı olarak bilinmesi ve bunların çalışma hayatına etkisinin dikkatlice tetkik edilmesi gere-kir. Bu makalede 4857 sayılı İş Kanunu’na tabi olarak çalışan bir işçinin sahip olduğu tüm izin hakları, ilgili mevzuat metinleri taranarak önce sınıflandırılmış ve sonra da bu izinlere ait uyulması gereken tüm kurallar tek tek açıklanmıştır. Böylece işçilerin izin hakkı konusunun her yönüyle açıklanması amaçlanmıştır.
The Battle Pass: a Mixed-Methods Investigation into a Growing Type of Video Game Monetisation
Authors: Petrovskaya Elena , Zendle David
Published: September 2020

As the profit model in the video game industry shifts from upfront payment to continuous exposure to in-game microtransactions, new forms of monetisation are on the rise. One such example is battle passes: time-limited content which provides players with an opportunity to access rewards not available within the main body of the game. In this paper, we apply a mixed-methods approach to conduct an in-depth examination of the Battle Pass feature in Dota 2. We consider 1) quantitatively, the prevalence of the Battle Pass within the Dota 2 player community, and 2) qualitatively, player attitudes towards this feature. Quantitative findings show that, despite the rising profitability of the Battle Pass, its presence has minimal effect on player uptake in Dota 2. Qualitative findings indicate complex player attitudes in which positive views on the Battle Pass contrast with concerns over elitism and difficulty in achieving rewards without spending money.
Meating conflict: Toward a model of ambivalence-motivated reduction of meat consumption

An increasing number of people are concerned about the ethics of eating meat despite enjoying doing so. In the present research, we examined whether the desire to resolve this ambivalence about eating meat leads to a reduction in meat consumption. Our model of ambivalence-motivated meat reduction proposes that the pervasive nature of evaluative conflict motivates meat avoidance, and we highlight two potential mechanisms involved: the anticipation of ambivalence reduction through behavioral change, and information seeking aimed at facilitating behavioral change. Study 1 drew on a 6-day food diary with 7,485 observations in a relatively representative sample to investigate the predictors of meat-related ambivalence and demonstrate its correlation with meat reduction. Two experiments showed that ambivalence-induced discomfort motivated participants to eat less meat when they introspected on their incongruent evaluations (Study 2 and 3), which was mediated by the hypothesized process variables (Study 3; preregistered). These findings in diverse samples from Germany, England, and the US (total N = 1,192) indicate that behavioral change is an important coping strategy to resolve ambivalent discomfort in the context of meat consumption. Our model of ambivalence-motivated meat reduction contributes to theorizing on the consequences of ambivalence and the psychology of (not) eating meat.

Racism exists at the individual and systemic level where power differentials and hierarchies oppress racial minorities. Canada’s auspicious history of colonialism and systemic racism puts Black, Indigenous, and People of Colour at-risk of poor psychological health, in addition to a host of other health-related concerns. As psychologists and trainees, our ethical duty, as outlined in our Code of Ethics, includes the responsibility to society. Recent sociocultural discussions and political movements (e.g., Black Lives Matter) highlight the need to confront and address issues of long-standing racism and inequity. As such, this commentary provides a brief review of the current and historical contexts of racism in psychology and highlights the need for a concrete, actionable plan to address these concerns. Consequently, we propose 18 recommendations to address the reviewed problems. We believe that these recommendations will help various settings that house and train psychologists as well as ones that regulate the profession (e.g., academic psychology departments, hospitals, private practices, governing bodies for psychology) to adopt anti-racist measures that provide a more inclusive environment.
What senior academics can do to support reproducible and open research: a short, three-step guide

Increasingly, policies are being introduced to reward and recognise open research practices, while the adoption of such practices into research routines is being facilitated by many grassroots initiatives. However, despite this widespread endorsement and support, open research is yet to be widely adopted, with early career researchers being the notable exception. For open research to become the norm, initiatives should engage academics from all career stages, particularly senior academics (namely senior lecturers, readers, professors) given their routine involvement in determining the quality of research. Senior academics, however, face unique challenges in implementing policy change and supporting grassroots initiatives. Given that - like all researchers - senior academics are in part motivated by self-interest, this paper lays out three feasible steps that senior academics can take to improve the quality and productivity of their research, that also serve to engender open research. These steps include a) change hiring criteria, b) change how scholarly outputs are credited, and c) change to funding and publishing with open research. The guidance we provide is accompanied by live, crowd-sourced material for further reading.
Compounded Vulnerability: The Consequences of Immigration Detention for Institutional Attachment and System Avoidance in Mixed-Immigration-Status Families
Authors: Patler Caitlin , Gonzalez Gabriela
Published: September 2020

While an extensive body of literature has analyzed the spillover and intergenerational consequences of mass incarceration, fewer studies explore the consequences of a parallel system: mass immigration detention. Every year, Immigration and Customs Enforcement imprisons hundreds of thousands of noncitizens as they await adjudication on their deportation proceedings, sometimes for months or years at a time. Many detained individuals have lived in the United States for decades and have spouses and/or dependent children that rely on them. This analysis brings together research on immigrant families, mass incarceration, and system avoidance to examine the spillover consequences of immigration detention. Using a multigenerational and multi-perspective research design, we analyze 104 interviews conducted in California with detained parents, non-detained spouses/partners, and their school-age children. Findings suggest that members of these mixed-status families may limit their engagement with surveilling institutions during a family member’s detention. These experiences are rooted in what we call compounded vulnerability—that is, both in the experience of parental/spousal confinement but also in their positionality as members of mixed-immigration-status families facing the possibility of deportation.
