IoT + AR: pervasive and augmented environments for “Digi-log” shopping experience
Authors: Jo Dongsik , Kim Gerard Jounghyun 
Published: January 2019

Abstract
The current bare Internet of Things (IoT) infrastructure has recently been extended to include smarter and more effective user interactions. Individual or meaningful sets and groups of IoT objects can be imbued with data and/or content in a distributed manner and efficiently utilized by the client. This distribution makes it possible to scale and customize interaction techniques such as augmented reality (AR). This paper proposes an architecture for combining the AR interface with IoT for an improved shopping experience. The proposed architecture is distributed and therefore scalable such that any IoT product can be accessed on the spot locally without any server restriction and provide intuitive AR-based visualization and interaction for a flexible product trial in the showroom. We identify three key architectural components required to support such a seamless and scalable AR service and experience for IoT-ready products: (1) object-centric data management and visualization, (2) mechanism for accessing, controlling, and interacting with the object, and (3) content exchange interoperability. We illustrate the possible scenarios of shopping in the future with the interactive and smart digital information combined with the analog, that is, the real world. A proof-of-concept implementation is presented as applied to such a “digital–analog” style of shopping. In addition, its usability is experimentally assessed as compared to using the conventional control interface. Our experimental study shows that the subjects clearly experience higher usability and greater satisfaction with AR-interactive shopping, thereby demonstrating the potential of the proposed approach.
Comparative studies on thin polycaprolactone-tricalcium phosphate composite scaffolds and its interaction with mesenchymal stem cells

Abstract

Background
Hybrid scaffolds combining biodegradable polymers and ceramic particles for control of cell adhesion and proliferation are interesting materials for tissue engineering applications. Combinations of biodegradable polymers and ceramics are to provide higher beneficial functionalities to tissue engineering scaffolds with addition of different cell specific bio-factors. Many such hybrid combinations have been reported by several researchers around the world by using various methods and solvents as well as bioactive matrix polymers to fabricate such biomaterials. However, thin hybrid scaffolds with high porosity, cell adhesion factors and biodegradability, as well as the ability to support stem cells often require tedious processes like electrospinning, freeze drying, etc. A simple method to develop porous biodegradable hybrid scaffolds with proper cell adhesion factors is still the need of the hour in tissue engineering and regenerative medicine.

Method
Thin biodegradable poly(ε-caprolactone) (PCL) based hybrid scaffolds were developed in combination with α-tricalcium phosphate (TCP) particles, gelatin and fibronectin separately and the fabricated scaffolds were evaluated systematically using human mesenchymal stem cells (hMSCs) for tissue engineering applications. A simple modified solvent casting method combined with gas foaming process was used to develop porous thin hybrid structures and compared their properties with those of corresponding non-porous hybrid scaffolds. The TCP particles distribution, morphology, biodegradability and functional groups of the different hybrid scaffolds were analyzed using energy-dispersive X-ray spectroscopy (EDX), light microscopy/scanning electron microscopy (SEM), buffer solutions and Fourier-transform infrared spectroscopy (FTIR), respectively The cellular and tissue regeneration behaviors such as in vitro cell attachment (live/dead assay), cell proliferation (CCK-8 assay) and histological studies were performed using hMSCs.

Results
Thin PCL-based hybrid scaffolds were fabricated using modified solvent casting method. Homogeneous distribution of TCP particles in the scaffolds were confirmed by EDX. Cellular interactions of the hybrid scaffolds demonstrated overall higher cell adhesion, proliferation and tissue regeneration on the non-porous thin films of PCL-TCP, PCL-TCP-gelatin and PCL-TCP-fibronectin. Coating of fibronectin was remarkable in induction of cell adhesion and proliferation.

Conclusions
The experimental results revealed that diversely designed PCL-TCP thin hybrid films showed high cell interaction and proliferation with hMSCs. From the results of the cell viability, attachment, proliferation and histological analyses as well as their biodegradation and coating effects, we conclude that these thin PCL-TCP hybrid films are suitable for tissue engineering applications.

Abstract
Emerging evidence indicates that ectopic skeletal muscle adiposity may be a risk factor for type 2 diabetes (T2D), especially in persons of African ancestry. In vitro studies suggest that a Wnt pathway inhibitor, Dickkopf-related protein 1 (DKK1), plays a role in adiposity regulation and could be a biomarker for adiposity in humans. The objective of this study was to test whether serum DKK1 levels relate to adiposity measures in a cohort from an African ancestry population at high risk for T2D. Fasting serum DKK1 was measured in a sample of 159 men of African ancestry aged ≥40 years (mean age ± SD, 63.5 ± 8.2 years; mean body mass index, 27.8 ± 4.5 kg/m2). Anthropometrics included total-body and trunk adiposity measured by dual-energy x-ray absorptiometry and lower-leg skeletal muscle density measured by CT [which reflects the intramuscular adiposity content (mg/cm3)]. Serum DKK1 was positively correlated with BMI (r = 0.20; P = 0.01), waist circumference (r = 0.15; P = 0.046), DXA total-body adiposity (r = 0.24; P = 0.003), and DXA trunk adiposity (r = 0.21; P = 0.009), independent of age and height. In addition, serum DKK1 was inversely correlated with skeletal muscle density (r = −0.25; P = 0.002), independent of age, BMI, and calf muscle area. No significant correlation was found between serum DKK1 and fasting serum glucose or insulin levels or insulin resistance estimated by homeostasis model assessment. These findings suggest that higher levels of serum DKK1 may be associated with greater overall, central, and ectopic skeletal muscle adiposity. Further studies are needed to unravel the potential role of DKK1 in the regulation of adiposity in humans.
Strategic Citizenship: Negotiating Public Law 280 in Arizona, 1953–1968
Authors: Osburn Katherine M. B. 
Published: January 2019

AbstractThis article analyzes how Arizona’s Indigenous leaders responded to attempts by the Arizona legislature to impose the state’s criminal and civil jurisdiction over Indian reservations under Public Law 280. Indigenous Arizonans’ activism included requiring tribal consent to any jurisdictional changes, significant cross-cultural cooperation in law enforcement, and insistence that non-Indian officials respect Indigenous methods of jurisprudence and learn from them. In each of these campaigns, Indigenous Arizonans articulated a vision of citizenship grounded in the opportunity to develop one’s “full potential” as an American citizen. This language signaled a hybrid political identity: sovereign Indigenous peoples with a unique contribution to make to America, who as Arizonans were entitled to participate in post–World War II prosperity as equal citizens.
Eccentric Sonnets: Ciaran Carson’s poetics in The Twelfth of Never
Authors: McIlfatrick-Ksenofontov Miriam 
Published: January 2019

The dialogic nature of language use and the impossibility of an uninfluenced work of literature complicate the notion of poet-as-originator. Yet originality persists as a sought-after quality in literature for both writers and readers. The article focuses on the Northern Irish poet, writer, and translator Ciaran Carson, known for his fascination with language as a medium and his linguistic experimentalism. In 1998, Carson published two collections of poetry: The Alexandrine Plan, translations of sonnets by Mallarmé, Baudelaire and Rimbaud, and The Twelfth of Never, a sequence of his own sonnets – both in rhyming alexandrines, suggestive of simultaneous composition. In its borrowed form, The Twelfth of Never offers a kaleidoscopic montage of motifs and discourses from Irish history, literature, folklore, music, and myth, and flits to and fro between Ireland, France, and Japan, evoking a never-land in which “everything is metaphor and simile”.
The article adopts a neuro-anthropological view of human culture as distributed cognition and of art as a way of knowing and self-reflectively putting the world together for both artist and audience. The analysis of Carson’s poems seeks to explicate how recognisable characters, emblems, and rhetoric appear in and are altered by unfamiliar guises and settings; how cultural symbols and literary forms are interrupted in the act of representing; and how the dreamlike quality of the collection depends on the looping and metamorphosing of motifs, images and voices from one poem to another. I suggest that this does not generate a chaotic textual product but amounts to an engaging reflection on the nature of originality in the making and making sense of poetry.
Poetic Dialogue from the Periphery of World Literature: Goethe’s Faust and the Korean Novel Kumo-shinwha
Authors: Chon Young-Ae 
Published: January 2019

A short but cardinal passage of Goethe’s Faust is the rhymed dialogue between Faust and Helen at their first encounter: the depiction of the very idealistic encounter consists of the process by which the ancient Greek mythical figure Helen learns about the difference and charm of the German poetic language, as well as its formal practices explained and guided by Faust. This passage is not only a description of the meeting of Helen and Faust but also, at the same time, verses on poetry and poetics.
This remarkable passage leads us to look into other cases in world literature. With this inquiry I have found out many similar cases in the literature of my own country and of other East Asian countries, Japan and China. As an example, here is presented a highly sublime poetic dialogue, drawn from an outstanding work of premodern Korean literature, the very first Korean “novel” Kumo-shinhwa, from the mid-fifteenth century: an exchange of ekphrasis, verses of picture description. With its perfect, more than perfect, rhyme, the poetic dialogue presents the symbolized union of two persons as a matter of course. By means of this poetic dialogue it will be pointed out how a standard canon does not remain itself but finds its incessant dialogues on behalf of other rather hidden works. Or in short: how the margin shifts itself through exchanges and translations.
Giant angiolipoma of the back complicated with ulceration and sepsis: unusual presentation of a rare benign tumour
Authors: Elfallal AH , Laimon YN , Emile SH 
Published: January 2019

A 63-year-old woman presented to the emergency unit with a huge (40 × 35 × 10 cm) oval-shaped pedunculated growth in the back with superficial ulceration in its lower aspect, associated with signs of sepsis. After adequate resuscitation, the patient was transferred to the operation theatre where the tumour was completely excised and the resultant wound was closed in primary manner using polypropylene sutures with suction drains inserted in the wound bed. The patient was discharged home after two days and was followed-up for two months. No wound complications were recorded on follow-up. Angiolipoma is a benign variant of lipoma that, despite what has been reported in the literature, may affect any age and any region of the body. Complications of angiolipoma may include ulceration, sepsis, gangrene and possible systemic inflammatory response syndrome which may pose a threat to the patient’s life, hence should be managed promptly after adequate patient preparation.
The Effect Of Erythropoietin Administration In Experimental Burns Wound Healing: An Animal Study
Authors: Sandhi Afriyanti , Wardhana Aditya 
Published: January 2019

Background: The hematopoietic growth factor erythropoietin (EPO) attracts attention due to its all-tissue-protective pleiotropic properties. The purpose of this study is to investigate the effect of EPO in experimental burn wounds healing.
Methods: Fifteen healthy Sprague-Dawley, strain of Rattus Novergicus weighing 300-350 grams, were prepared to achieve deep dermal burns. Animals were randomized to receive either low-dose EPO injection (600 IU/mL), high-dose EPO injection (3000 IU/mL) or nothing (control group). After 14 days of observations, quantitative and qualitative assessments of wound healing was determined.
Results: The size of the wound area and re-epithelialization rate percentage was determined on Day-0, Day-5, Day-10, and Day-14. The average of raw surface areas measurement (p value: 0.012 in day-5; 0.009 in day-10 and 0.000 in day-14) and healing percentage of the lesions (p value: 0.011 in day-5; 0.016 in day-10 and 0.010 in day-14) were significantly best in the low-dose EPO grup compared to the control group and high-dose EPO grup. The histopathology evaluation revealed that the highest score for for re-epithelialization, granulation tissue and neo-angiogenesis were achieved by the low-dose EPO injection group than in both control and high-dose EPO injection groups.
Conclusion: In this animal study using Sprague-Dawley rats, Recombinant Human EPO (rHuEPO) injection administration prompted the evidences of improved re-epithelialization and wound healing process of the skin caused by deep dermal burns. These findings may lead to a new therapeutic approach to improve the clinical outcomes for the management of burns wound healing.

Authors: Herlambang Beni , Budiman Budiman 
Published: January 2019

Background: This case report gives prominence to the risk of delayed, possibly life - threatening bleeding following mid-facial fractures.
Methods: A 42-year-old male was involved in an accident during which he suffered from right zygomaticomaxillary complex fractures with massive bleeding. The hemoglobin level was decreased from 11 to 5 g/dL, suspected caused by rupture of internal maxillary artery. Incidence of massive bleeding due to zygomaticomaxillary complex fracture is quite rare. Patient also felt right visual loss due to retrobulbar hematoma compression. He was given nasal tampon and transfusion in referral hospital. The patient had fracture reconstruction (reduction and fixation), ligation of right facial artery and temporary ligation of external carotid artery with Ethiloop for 5 days. Nevertheless, the bleeding still occurred. The patient then underwent Digital Subtraction Angiography (DSA) and coiling procedure from radiologic intervention. Twenty days after last procedure, we ligated the right external carotid artery due to recurrence of bleeding.
Results: There are many modalities and procedure for the therapy of massive bleeding on midface fracture, ranging from conservative, minimal invasive to operative surgery. Patient that has gone through DSA procedure can still bleed. After ligation of external carotid artery, no more bleeding occurred.
Conclusion: Patient suffering from extensive midfacial fracture, the internal maxillary artery and its branches are at special risk of injury due to their close anatomical relationship to bony structures. Its bleeding is possibly life threatening. Tampon and nasal packing are non-essential initial treatment, but digital pressure procedure can be performed to stop the bleeding temporarily. Ligation of external carotid artery is the best choice of treatment for permanent outcome.

Locuções

Published: January 2019

Neste trabalho, propomos demonstrar, a partir da análise da definição de alguns dicionários e de um teórico da Lexicografia, como o termo locução vem sendo conceituado. Para isso, partimos de um dicionário de língua latina, de um de Linguística e de alguns dicionários de língua geral (de diferentes épocas). Em seguida, por tratar-se também de nossa área de estudos, discutimos o conceito de locução, com base nas contribuições do lexicógrafo Julio Casares Sánchez, uma das grandes referências sobre o tema, nos estudos fraseológicos. Notamos que essas obras lexicográficas, em alguns momentos, aproximam a sua definição ou ao que se refere à pronúncia, ou tendem a uma classificação gramatical e/ou lexical. Todavia, sempre se remetem às locuções como um agrupamento de palavras. Casares, por sua vez, a respeito dessas unidades, as conceitua também como uma combinação estável de duas ou mais palavras pertencentes ao âmbito da oração, mas salienta que seu significado provém da soma dos significados contidos em seus componentes.

Abstract
The aim of the paper was to develop a device (“pin-on-disc” type) for the measurement of friction in plane friction couplings with sliding movement. On tribometric device (made in our laboratory) we can measure the friction force, friction coefficient and wear, for different loading conditions, speeds, time and material coupling.
For the measurement of the frictional force as well as of the coefficients of friction, mainly the method with a resistive tensiometric transducer is used. With a DataQ DI 245 data acquisition board it is possible to record up to 2 kHz frequencies in the range of -10 ÷ +10 mV with a resolution of 13 bits. To test the functionality of the device, a preliminary test was carried out for a steel pin- on- cast iron disc, for different values of the normal pushing force. The device was calibrated and the measurement results were recorded and processed on the computer.

Authors: Braatz João Gomes 
Published: January 2019

Nesta pesquisa, procura-se analisar as características e significado da guerra evidenciados no texto indiano Bhagavad Gita, pertencente à obra Mahabharata. Sua produção é posterior à dos grandes Vedas, os primeiros textos sagrados do que viria a tornar-se o Hinduísmo. Tendo seus versos inteiramente compilados durante o século IV AEC, a obra adquiriu o formato atual aproximadamente pelo século V, já que se acredita que o processo de produção tenha durado em torno de um milênio, por meio da tradição oral. É no Bhagavad Gita que ocorre o diálogo entre o deus Krishna e Arjuna, o herói da história. Neste capítulo, consta o ensinamento divino passado para o guerreiro, que trata do sentido da vida e do papel do guerreiro na sociedade védica, tornando a obra referência para a varna dos Kshatriyas (xátrias, a varna guerreira).Palavras-chave: Filosofia guerreira, Bhagavad Gita, Índia.
