The objective of our study was to evaluate the aseptic technique used in interventional rheumatology by Moroccan and Tunisian rheumatologists. We performed an online survey among rheumatologists from Morocco and Tunisia. The questionnaire included 15 questions with single and multiple-choice answers and three open sections for freetext comments. An online survey was prepared and sent to 380 rheumatologists. One hundred and four rheumatologists (27.36%) replied to the survey. More than half of the participants (56.7%) were from Tunisia and 43.3% were from Morocco. Interventional procedures on superficial joints were performed by all participants. Ultrasonography was used by 41.3% of respondents to guide interventional procedures. Regarding the aseptic precautions taken to avoid infection, the majority of participants used povidone iodine to clean the skin and only 8.7% wore a mask. Hand washing alone without gloves wearing was done by 19.2% of participants. 2.9% of participants reported a history of iatrogenic septic arthritis and the duration of practice was the only factor associated with its occurrence (P=0.007). Our study showed that aseptic technique used during interventional rheumatologic procedures is heterogeneous. However, the majority of participants were aware of its necessity to avoid iatrogenic septic arthritis.

Published: August 2021

Osteoarthritis leads to articular cartilage destruction. The treatments reduce pain and improve function by using physical therapy, anti-inflammatory drugs, and surgical intervention, when necessary. Several studies suggest that 30% of patients undergoing knee replacement are not satisfied with results, thus highlighting a possible correlation with quadriceps strength and activities of daily living performance. Some authors studied the connection between clinical and radiological variables and quadriceps thickness, measured by ultrasound in patients with knee replacement. We conducted a cross-sectional study, enrolling 28 patient submitted to the same rehabilitation protocol (4 weeks), after knee arthroplasty, evaluated at admission (T0) and discharge, (TF), using ultrasound for measurement of vastus medialis thickness, and functional scales for abilities and pain. We noted that patients with a cross-sectional diameter of vastus medialis larger than 10 millimetres at the admission manifested less pain and improved their function and abilities values at TF compared to patients with a cross-sectional diameter smaller than 10 millimetres, and showed a better recovery process. Our study demonstrates that the weakness of vastus medialis could be an independent factor which can impact the outcome of patients submitted to arthroplasty of knee, and that it can be evaluated using ultrasound.
DreamSenseMemory - a Gestalt-based dream-work approach embracing all our senses
Authors: Holzinger Brigitte , Nierwetberg Franziska , Cosentino Larissa , Mayer Lucille
Published: August 2021

Gestalt therapists believe that their task is to help their clients to experience repressed, ambivalent, and unpleasant things in order to accept and implement them in their whole self. To implement those ‘things’, those elements of the self, they need to be uncovered first, which is a process that often is achieved by dream work, as messages from the unconscious that are stuck in our dreams can be revealed by certain Gestalt-therapy methods. The method in focus is the newly developed DreamSenseMemory technique which is based on neurological findings on how the senses at play influence memory processing. Dream work with the DreamSenseMemory method has the advantage that by using this method on a regular basis, dream content will not only be remembered more often but also in more detail. Thus, effectively supporting dream work and its process of understanding the message of the unconscious, accepting the elements withing and implementing them in the self.
Nightmares and bad dreams among individuals with musculoskeletal pain: a link to vitamin D and calcium
Authors: Abdul-Razzak Khalid K. , Alkhatatbeh Mohammad J.
Published: August 2021

Nightmares are frightening or disturbing dreams that awaken sleepers while bad dreams are disturbing dreams that do not awaken sleepers. Both types are known to be associated with psychological symptoms including anxiety and depression. Chronic pain is often comorbid with psychological symptoms and vitamin D deficiency increases risk of chronic musculoskeletal pain (MSP), which in turn is associated with increased risk of anxiety and depression. We aimed to investigate associations between types of dreams, psychological symptoms, vitamin D, and calcium intake in individuals with MSP. The study included 191 outpatients with MSP and 191 age/gender matched healthy controls. Psychological symptoms were assessed using Hospital Anxiety and Depression Scale. Serum vitamin D was measured and daily calcium intake was estimated. Participants were asked about types of their dreams (normal, bad, or nightmares) during the past month. Binary logistic regression was used to find predictors of MSP and bad dreams and nightmares. Bad dreams and nightmares, vitamin D deficiency, low calcium intake, anxiety, and depression were more prevalent in cases versus controls (Ps<0.001). Chi-square analyses showed that types of dreams were associated with anxiety, depression, and MSP (Ps<0.001). Participants with normal dreams had higher vitamin D (P<0.01) and calcium intake (P<0.001) and lower anxiety and depression scores (Ps<0.001) compared to participants with bad dreams and nightmares. Anxiety, depression and MSP were predictors for bad dreams and nightmares. Further studies are required to assess if vitamin D supplementation and increasing calcium intake may improve MSP, psychological symptoms and thus prevent nightmares and bad dreams.

Published: August 2021

Background: Giant lip hemangioma is a rare disease that may cause difficulty in preoxygenation and ventilation when using face masks and intubation during general anesthesia induction.Case: A laparoscopic cholecystectomy was planned for a 77-year-old woman. The patient had a giant lower lip hemangioma that was 12 x 5 x 5 cm, which made preoxygenation and ventilation through a face mask impossible and put her at risk of hemangioma rupture. We preoxygenated her through a high-flow nasal cannula (HFNC). Following propofol and succinylcholine administration, we intubated the patient with a video laryngoscope without desaturation, hemangioma rupture, or CO2 retention. Conclusions: HFNC is a useful tool when difficult intubation is expected in patients who have problems using conventional face masks.
Anesthesia management in patient with nonobstructive hypertrophic cardiomyopathy with severe mitral valvular regurgitation with severe pulmonary artery hypertension for mitral valve replacement
Authors: Mudgalkar Nikhil N.
Published: August 2021

Hypertrophic cardiomyopathy (HCM) is a genetic disorder that is characterized by left ventricular hypertrophy unexplained by secondary causes and a nondilated left ventricle with preserved or increased ejection fraction. Mitral regurgitation is common in HCM secondary to distortion of mitral valve apparatus leading to systolic anterior motion. We report a case of HCM with rheumatic involvement of mitral valve with severe pulmonary artery hypertension and atrial fibrillation. With regard to hemodynamic management in patients with postcardiac surgery status, anesthetic management seems to be a “walk a tight rope.”
Dental implants and its use in children
Authors: Chawla Dipti , Deep Aman , Chhatwalia Sumit
Published: August 2021

Among the various congenital dental abnormalities in children, loss of tooth due to trauma and hypodontia are few that are most prevalent. A wide range of treatment modalities are available for these abnormalities, however, removable prosthesis is the most common treatment option to be used, but a pitfall of this method is that it may increase the residual alveolar bone resorption and other problems related to periodontal support of the remaining teeth. Dental implants, another treatment modality, are generally advocated in adults or young patients that are beyond their craniofacial growth potential. This comprehensive review will discuss the use of dental implants in normal growing patients and some special scenarios including orthodontic consideration and mini-implant use in pediatric population. This review sorted the literature in main themes of influence of growth on the usage of dental implants in children; use of dental implants in children suffering from ectodermal dysplasia; use of dental implants in traumatic dental injuries sustained in children; and for orthodontics intervention during childhood. The literature was searched using databases such as PubMed, Scopus, MEDLINE, and Google. The titles and abstracts were screened, and full text was retrieved for publications that studied the use of dental implants in children in any form of intervention. The results indicated that scientific studies have documented high functional and esthetic results in cases of prosthetic treatments on implants, min-implants in children. However, the use of implants in children is high restricted to anterior mandibular region, with most clinicians opting for growth completion before implant placements. The establishment of the mastication, speech function, and normal appearance is highly crucial for growth of the jaws and facial bones. However, isolated use of mini-implants in growing children has definitely broaden the idea of the use of implant modification in children, yet to achieve maturation.
Recurrent extranodal cutaneous Rosai–Dorfman disease of the breast
Authors: Chen Sherry Ying-Hsuan , Shih Shen-Liang , Wu Chun-Chieh
Published: August 2021

Rosai–Dorfman disease (RDD) is a rare proliferative histiocytic disorder, often clinically present with massive lymphadenopathy, which typically involves the cervical lymph nodes and is limited to head and neck. It can also be found extranodally, and an unusual site of incidence is the breast. Although it may be a benign disease, it can mimic malignancy based on features of irregularity and lymphadenopathy; thus, the recognition of this condition before any unnecessary therapeutic management is important. A definitive diagnosis is dependent on pathologic proof. This report describes a 26-year-old Asian female with a recurrent RDD, who presents with a firm and visible nodule in the breast and is treated relatively conservatively by local surgery.

Published: August 2021

Odontodysplasia is a rare nonhereditary developmental anomaly of dental hard tissue with unknown etiology, arising from both ectodermal and mesodermal components. Hitchin in 1934 first described it as a localized arrest of tooth development generally affecting one quadrant of the jaw. When it just affects one quadrant, it is referred to as “regional odontodysplasia,” but when it crosses the midline and affects more than one quadrant, it is referred to as “generalised odontodysplasia.” In this two case series, various types of odontodysplasia have been described, one of which is confined to a single quadrant and the other crossing the midline. The cases of odontodysplasia can only be treated by multidisciplinary approach and restorative and prosthetic rehabilitation and regular follow-up require for improving the quality of life of patients.

Published: August 2021

PurposeThe value of the genomic profiling by targeted gene-sequencing on radiation therapy response prediction was evaluated through integrated analysis including clinical information. Radiation response prediction model was constructed based on the analyzed findings.Materials and MethodsPatients who had the tumor sequenced using institutional cancer panel after informed consent and received radiotherapy for the measurable disease served as the target cohort. Patients with irradiated tumor locally controlled for more than 6 months after radiotherapy were defined as the durable local control (DLC) group, otherwise, non-durable local control (NDLC) group. Significant genomic factors and domain knowledge were used to develop the Bayesian Network model to predict radiotherapy response.ResultsAltogether, 88 patients were collected for analysis. Of those, 41 (43.6%) and 47 (54.4%) patients were classified as the NDLC and DLC group, respectively. Somatic mutations of NOTCH2 and BCL were enriched in the NDLC group, whereas, mutations of CHEK2, MSH2, and NOTCH1 were more frequently found in the DLC group. Altered DNA repair pathway was associated with better local failure–free survival (hazard ratio, 0.40; 95% confidence interval, 0.19 to 0.86; p=0.014). Smoking somatic signature was found more frequently in the DLC group. Area under the receiver operating characteristic curve of the Bayesian network model predicting probability of 6-month local control was 0.83.ConclusionDurable radiation response was associated with alterations of DNA repair pathway and smoking somatic signature. Bayesian network model could provide helpful insights for high precision radiotherapy. However, these findings should be verified in prospective cohort for further individualization.
On the Moy–Prasad filtration

Published: August 2021

Let

K

be a maximal unramified extension of a non-archimedean local field with arbitrary residual characteristic

p

. Let

G

be a reductive group over

. We show that the associated Moy–Prasad filtration representations are in a certain sense independent of

. We also establish descriptions of these representations in terms of explicit Weyl modules and as representations occurring in a generalized Vinberg–Levy theory.

As an application, we provide necessary and sufficient conditions for the existence of stable vectors in Moy–Prasad filtration representations, which extend earlier results by Reeder and Yu (which required

p

to be large) and by Romano and the present author (which required

G

to be absolutely simple and split). This yields new supercuspidal representations.

We also treat reductive groups

that are not necessarily split over a tamely ramified field extension.
Spanning surfaces in 3-graphs

Published: August 2021

We prove a topological extension of Dirac's theorem suggested by Gowers in 2005: for any connected, closed surface

\mathscr{S}

, we show that any two-dimensional simplicial complex on

n

vertices in which each pair of vertices belongs to at least

\frac n3 + o(n)

facets contains a homeomorph of

\mathscr{S}

spanning all the vertices. This result is asymptotically sharp, and implies in particular that any 3-uniform hypergraph on

n

vertices with minimum codegree exceeding

\frac n3+o(n)

contains a spanning triangulation of the sphere.
Soliton dynamics for the 1D NLKG equation with symmetry and in the absence of internal modes
Authors: Kowalczyk Michał , Martel Yvan , Muñoz Claudio
Published: August 2021

In this paper, we consider the dynamics of even solutions of the one-dimensional nonlinear Klein–Gordon equation

\partial_t^2 \phi - \partial_x^2 \phi + \phi - |\phi|^{2\alpha} \phi =0

for

\alpha>1

, in the vicinity of the unstable soliton

\smash{Q}

. Our main result is that stability in the energy space

H^1(\mathbb{R})\times L^2(\mathbb{R})

implies asymptotics stability in a local energy norm. In particular, there exists a Lipschitz graph of initial data leading to stable and asymptotically stable trajectories. The condition

\alpha>1

corresponds to cases where the linearized operator around

Q

has no resonance and no internal mode. Recall that the case

\alpha>2

is treated by Krieger, Nakanishi and Schlag [Math. Z. 272 (2012)] using Strichartz and other local dispersive estimates. Since these tools are not available for low power nonlinearities, our approach is based on virial type estimates and the particular structure of the linearized operator observed by Chang, Gustafson, Nakanishi and Tsai [SIAM J. Math. Anal. 39 (2007/08)].

Migration, Farmer-Herder Conflict and the Challenges of Peacebuilding in the Agogo Traditional Area, Ghana
Authors: Setrana Mary Boatemaa , Kyei Justice Richard Kwabena Owusu
Published: August 2021

Recently, communities in Agogo Traditional Area (ATA) have witnessed an increasing spate of violence leading to loss of lives, loss of livelihoods, insecurity and severe injury among others. This article explores the “local” in peacebuilding by addressing the following research questions: first, how do Agogo indigenes in the diaspora contribute to peacebuilding in Agogo Traditional Area? Second, in which ways do the engagement of Fulani herders and indigenous farmers influence the process of peacebuilding in Agogo Traditional Area? The article employed in-depth interviews, participant observation, key informant interviews and focus group discussions in the data collection process. From an interdisciplinary perspective, the research has introduced the activities of transnational migrants into the discourse of peacebuilding as it positions Ghanaians in the diaspora as local actors engaged in the farmer-herder conflict in ATA. This study has shown that in the case of ATA, despite the potential benefits of the local peacebuilding including the contribution of the diaspora, it is bedeviled with challenges such as mistrust and inadequate resources. The article recommends that local peacebuilding be detached from adjudication in the court of law because the local actors perceive the court as external and ambivalent to the cultural context of local conflicts.
Assessment of the impact of ungoverned spaces on insurgency in Borno State, Nigeria

Published: August 2021

This study examines the relationship between ungoverned spaces and insurgency in the Borno State, Nigeria. The aim is to understand the influence of geographical variables on the activities of insurgence. The study used satellite data, population data and data on insurgency attack in the study area. Normalized Difference Vegetation Index, percentage rise in slope analysis and reclassification were used for the satellite data processing.  Geographically Weighted Regression (GWR) models was employed for data analysis. The findings revealed that LGAs in the central and the southern parts of the state recorded the highest number of insurgency attacks. The central and far northern part of the state has more vegetal cover, which has influenced the high incidence of insurgency attack observed. In addition, the very high incidence of insurgency attack (145) observed in Gwoza LGA, is largely attributed to the presence of the Gwoza Mountain, which is one of the main strong holds of the insurgents in Borno State. The GWR analysis reveals that the performance of the model with the population density was much better than the other variables with a corrected Akaike Information Criterion (AICc) value of 273.15, R-Squared values of 0.0323, 0.0224, 0.0203 and 0.8901 for the undulating terrain, vegetation, combination of vegetation and undulating terrain, and population density respectively. Thus, the study concludes that vegetal cover and population density have more influence on insurgency attack in the study area. Hence, the need for policy makers and security establishments to properly monitor the forested areas.

Published: August 2021

The present application scenarios of the Internet of Things (IoT) often require the equipment to be adaptable, the resource allocation to be efficient, and the signal monitoring and transmission to be effective. However, the existing algorithms cannot solve the problem of system capacity reduction caused by the mutual interference between regions in data rates. Aiming at effectively improving the performance of the IoT monitoring system and ensuring the fairness of each monitoring terminal, this paper attempts to explore interference suppression and resource allocation strategies based on IoT monitoring. First, the paper established an IoT monitoring network model, and elaborated on interference suppression strategies for inter-layer interferences of “Macro Base Station (BS) – Micro Cells” and “Micro BS – Macro Cells” and for intra-layer interference that include the interference between local monitoring networks and interference between terminals in local area networks; then, the paper proposed a sub-carrier resource allocation scheme for IoT monitoring system with multiple inputs and outputs and a water-filling strategy of system channel power; at last, experimental results verified the effectiveness of the proposed interference suppression and resource allocation algorithm.

Yer seçim sorunları Endüstri Mühendisliği alanının en çok çalışılan konularından biri olup hastane yeri seçimi konusunda ise diğer yapılara oranla çok geniş çaplı araştırmalar yapılmadığı görülmektedir. Hastanelerin ekonomik yapı içerisindeki yerleri, toplum sağlığı açısından taşıdıkları önem, göç olgusuyla beraber yaşanan kapasite sorunları gibi unsurlar göz önüne alındığında hastane yeri seçiminin taşıdığı stratejik önem daha iyi anlaşılmaktadır. Bu çalışmada, karar uzmanlarının görüşlerindeki olası belirsizlikleri daha iyi sayısallaştırma yeteneğine sahip olan sezgisel bulanık sayılar (intiutionistic fuzzy numbers) kullanılarak hastane yeri seçimi konusunda özgün bir bulanık karar destek modeli önerisi getirilmektedir. Yer seçim uzmanları ve sağlık yöneticilerinden oluşan bir ekibin kurulması ve bu ekibin olası hastane yeri adaylarını belli kriterler çerçevesinde değerlendirmesi yoluyla bilgi toplama işlemlerinin yapıldığı yöntemde, ikinci özgün yan hastane yeri seçiminde uzmanların ağırlıklarının da hesaba katıldığı bir grup karar verme yaklaşımının öneriliyor oluşudur. Yöntemde nesnel ağırlıklandırma yoluyla uzman görüşlerindeki öznellik sınırlandırılmakta, sıralı ağırlıklı ortalama (OWA-ordered weighted averaging) yönteminin kriter ağırlıklandırmada tercih edilmesi ile son özgün yan ortaya konulmaktadır. Analiz yöntemi olarak ise sezgisel bulanık VIKOR yaklaşımından faydalanılmaktadır. Önerilen model, İstanbul’un bir ilçesi için uygulanmış ve analiz sonuçları paylaşılarak ileriki çalışmalar için öneriler getirilmiştir.
SIX SIGMA IN PLASTIC INJECTION MOLDING: REUSE DEFECTIVE PARTS IN NEW ARTICLE PRODUCTION AS RAW MATERIAL INPUT OR NOT?
Authors: ULUSKAN Meryem
Published: August 2021

In production plants, re-processing of defective products and re-incorporating them into production as raw materials provides the advantages of reducing scrap and efficient use of material. However, using recycled defective plastic parts as raw materials in the production of new parts in plastic injection processes can create aesthetic problems for the final product. On the other hand, the aesthetic dimension of quality that fulfills customer expectations provides competitive advantage. Considering this, in this study, the root cause of the aesthetic problem that occurs as discoloration of a particular component manufactured in a plastic injection facility operating in the white goods industry was revealed and improvement was made. Six Sigma DMAIC methodology was applied to reduce high scrap rates caused by discoloration errors, and it was determined that the error was caused by reusing scrap plastic parts as raw materials in the production of new articles. With the elimination of this cause, the process capability was improved, the 3 sigma process capability was increased to the level of 4.7 sigma and the aesthetic appearance of the product was improved. This study has shown that the reutilization of defective plastic parts as raw material input in new article production is not a viable approach for particular products such as white goods products.

Bu çalışmanın ilgilendiği konu, hammaddelerin hangi raf alanına atanacağına karar verilmesi ve maksimum miktarda atanmasıdır. Bu karar verilirken, alanın sınırlı olduğu, tüm hammaddelerin kendi aralarında aynı önem seviyesine sahip olmadığı, farklı stok ve palet büyüklüğüne sahip olduğu düşünmelidir. Mevcut çalışmalarda, raf boyutları ve paletler tek boyutlu veya standart ölçülerle hesaplanmaktadır. Ancak, gerçek hayatta raf ve palet boyutları genişlik, yükseklik ve derinlik açısından farklı ölçülere sahiptir. Bu çalışmadaki gerçek uygulamada, tüm durumların matematiksel modeli oluşturulmuştur. Çalışmada kurulan model, önem derecelerine göre optimum miktarların atandığını göstermektedir.

Öncelikle ABC analizi kullanılarak A sınıfındaki hammaddeler belirlenmiştir. Çok kriterli karar verme yöntemi ile bu hammaddelerin önem katsayıları belirlenmiş ve doğrusal modelin amaç fonksiyonu oluşturulabilmesi için ana kriterler 4 farklı uzmanın hammaddeleri sınıflandırabileceği şekilde belirlenmiştir. Uzmanların sahip olduğu farklı görüşleri ve hammaddeler için belirlenen kriterler arasındaki ilişkileri göz ardı etmeden model oluşturmak için Bulanık Analitik Ağ Süreci kullanılmıştır. Matematiksel modelin kısıt denklemleriyse blok raf sistemlerine ait hücrelerin değişen kapasiteleri ve hammaddelerin maksimum-minimum stok değerlerine göre oluşturulmuştur. Sonuç olarak, hangi rafta hangi hammaddenin ne kadar tutulacağının belirlenmesi ile depo görevlisi yönlendirilmiştir.

Banking environment, traditional with an established physically collocated work culture, has been disrupted by the COVID-19 pandemic. It triggered the evolution of innovation management processes to handle the issues related to spatial spread, fuzziness and collective information development during idea evaluation. In this paper, Vakıfbank Innovation Management System (V-IMS) was exemplified utilizing ICT for virtual collaboration, MCDM (Multi Criteria Decision Making) methods within stage-gates, transforming knowledge and exploiting collaboration at the fuzzy front end. There, physically collocated work culture was transformed into delocated collaboration with an agile approach utilizing lean information flow, which emphasizes the people exchanging tacit into explicit knowledge on the move rather than long documentations. Moreover, the culture of innovation has been fostered, innovation management metrics were improved significantly and both the number of sessions and ideas presented in the sessions were found to be increased. It was observed that the satisfaction level and innovation commitment of the employees were increased with the new system as well.

Beyond Egalitarianism
Authors: Lorke Christoph
Published: August 2021

Despite all the political and ideological pronouncements, there were also various forms of social inequality in the ‘real existing socialism’ of the GDR (German Democratic Republic). These have been extensively studied at the latest since the construction of the Berlin Wall. Since these years, there has been an intensified preoccupation with socially deviant living conditions, which have been documented statistically. How- ever, these figures raised questions about the limits of socialist communisation and the realisation of the ideologically articulated goal of bringing about a convergence of the ‘classes and strata’. Therefore, the goal was to synchronize these figures with the state’s self-image, which in turn revealed numerous contradictions. Based on a deconstruction of contemporary statistical measurement procedures as well as studies and the resulting interpretations of social inequality, the article first proposes a phase classification of this approach to social differentiation. In a further step, the resulting intended and unintended effects are illuminated.

Physiotherapy in Australia - Where to Now?
Authors: Struber Janet
Published: August 2021

The physiotherapy profession in Australia appears to have been caught unawares by the rapidly changing demography of health services and now seems to lack a clear identity and vision. Despite being a highly competitive profession to enter, attrition rates are high. This paper reflects on the history of physiotherapy in Australia and the dichotomy of paradigms it now faces, and suggests a possible option for the future, given that existing physiotherapy roles appear difficult to sustain in our current health care climate.

Arab American Feminism: The Political and the Literary Strategies of Re-writing between Borders in Contemporary Post-9/11 Fiction by Women Writers
Authors: Zbidi Nawel
Published: August 2021

Undeniably, Arab American women occupy a debatable position in mainstream culture and politics. Because of their former invisibility, they started to claim their presence and to fight for their rights in post-9/11 America. They ardently become aware of their submission to both Arab patriarchy and sexism and the necessity to fight against this denigrating position. Likewise, they realise that they were silenced in discourses against Arab and Muslim discrimination in the United States. This paper focuses on the ways they have been challenging these discriminatory and invisibilizing discourses against Arab women through shedding light on their Transnational Feminist concerns in their writings, in which they have created a site to communicate anti-discrimination discourses, and to oppose the stereotypical monolithic portrayals of Arab men that are mainly due to the hypervisibility and the demonization of Arabs in post- 9/11 America. Additionally, it highlights how the Shehrazadian narrative strategy in contemporary Arab American women’s writing engulfs several features and illustrations of confrontation and resistance to the stereotypical representations of Arab women, mainly in the American popular culture. Indeed, Shehrazade and her narrative strategies become in this context a collective means for re-writing, reviving and redefining grandmother figures from the past. Shehrazed’s storytelling, as a life-serving strategy, becomes a metaphor for the urgency of exploring why and how figures like Shehrazade are translated across cultures and how Orientalism shapes such translation.

Mục tiêu của nghiên cứu này là đánh giá khả năng sinh trưởng, thành phần thân thịt xẻ của 3 tổ hợp bò lai hướng thịt giữa bò cái nền Lai Brahman với các giống bò đực Charolais, Droughtmaster và Red Angus giai đoạn vỗ béo nuôi tại tỉnh Quảng Ngãi. Nghiên cứu thực hiện trên 18 bò lai (6 bò/tổ hợp lai) 18 tháng tuổi, thời gian nuôi 3 tháng. Kết thúc giai đoạn nuôi, 4 bò/tổ hợp lai được mổ để đánh giá năng suất thịt. Kết quả cho thấy, các tổ hợp bò lai Charolais × Lai Brahman, Droughmaster × Lai Brahman và bò Red Angus × Lai Brahman có khối lượng lúc 21 tháng tuổi lần lượt là 523,7; 465 và 484 kg/con, tăng khối lượng trung bình sau 3 tháng nuôi của 3 tổ hợp bò lai lần lượt là 1.282; 1.039 và 1.134 g/ngày. Khối lượng thịt xẻ (kg/con) và tỷ lệ thịt xẻ (% khối lượng giết mổ) tương ứng với các tổ hợp bò lai Charolais × Lai Brahman, Droughmaster × Lai Brahman và bò Red Angus × Lai Brahman lần lượt là 312,6; 275,6 và 295,5 kg và 60,6; 60,3 và 62,1%; Tỷ lệ thịt tinh của ba tổ hợp bò lai lần lượt tương ứng là 45,2%; 43,9% và 42,6%. Trong 3 tổ hợp lai thì xu hướng năng suất thịt xẻ của tổ hợp bò lai Charolais × Lai Brahman là cao nhất, tiếp đến là bò lai Red Angus × Lai Brahman, thấp nhất là bò lai Droughtmaster × Lai Brahman. Các tổ hợp bò lai hướng thịt này nên được nhân rộng tại Quảng Ngãi và các địa phương có điều kiện chăn nuôi tương tự.

Published: August 2021

Home automation is now extremely common in Internet of things services and devices with a range of assurances to improve health, lifestyle, and customer wellbeing. In terms of its success and apparent utility for humans, intelligent homes possess various safety concerns resulting from the diversified, vast-range, and nuanced nature of IoT. Previous studies have talked about security and privacy issues. However, we observe that they have not addressed the risk assessment of each smart home component and corresponding security objective along with additional factors that affect a smart home security posture. In this study, we have proposed a framework defining a standard level of security and then analyzing each component concerning it. There are so many vulnerabilities, but all cannot be assessed due to the heterogeneity of devices and their connection in a small network. IoT can support a wide range of technologies and programs in various domains, including smart cities and smart houses. For monitoring, data exchange, and other operations in the given service, IoT smart objects communicate with other elements such as proxies, mobile devices, and data collectors. While such components help solve various social issues and provide consumers with modern advanced services, their restricted computing capacities render them vulnerable to well-known protection and privacy risks.
