Authors: Wahyuni Hana , Vanany Iwan , Ciptomulyono Udisubakti 
Published: July 2019

Purpose: Researchers have been actively investigating various issues concerning food safety and halal food in the supply chain. The ultimate goal is to provide guarantees for quality and conformance regarding food standards and demanding expectation from the consumers. We review a set of two-decade food safety and halal food in supply chain (SC) literature from 1990 to 2018 (month of February) in order to pinpoint the problems, models, solution approaches and more importantly, the future directions of this field. Design/methodology/approach: Our method employs the 120 published articles on food safety and halal food in SC research. Various techniques from statistics, bibliometrics, and analytics are systematically deployed to gain insights on how the literature address these two topics.Findings: The predominant contributing articles, authors, affiliations, and keywords have been reviewed, clustered, and thoroughly analyzed. Through systematic graphical and clustering analyses, four major clusters regarding food safety and two clusters in halal food in SC research have been identified as the most promising and potential future for research opportunities.Research limitations/implications: This study focuses on articles that discuss food safety and halal.Practical implications: Our findings provide valuable insights to understand the major clusters of the research endeavour along with the plausible pathways to where they would likely develop in the future. With these insights, researchers and practitioners shall be able to devise initiatives that are of high relevance and significance in the near future.Social implications: This research provides an understanding to the reader about the relationship between food safety and halal.Originality/value: This paper provides the first systematic overview of food safety and halal food for supply chain researchers to see the big picture of the field. Serving as the thread connecting research endeavour in these two research areas, our novel work highlights how the work is connected, which research clusters have been the center-of-attention during the last two decades, and consequently, which areas are still lacking an investigation. We believe that people in both academia and industry who are keen to develop a rigorous solution to ensuring food safety and food halal-ness to satisfy global market requirement will be benefitting the most from our analysis.
Displacement of the Foveal Retinal Layers After Macular Hole Surgery Assessed Using En Face Optical Coherence Tomography Images
Authors: Lee Seung Min , Park Keun Heung , Kwon Han Jo , Park Sung Who , Byon Ik Soo , Lee Ji Eun 
Published: July 2019

BACKGROUND AND OBJECTIVE:
To investigate the displacement of foveal retinal layers in surgically closed macular holes (MHs) after removal of the internal limiting membrane (ILM).

PATIENTS AND METHODS:
Medical records of 26 consecutive patients who underwent vitrectomy and removal of the ILM for idiopathic MH were retrospectively reviewed. En face optical coherence tomography images were exported at the level of the choroid, ellipsoid zone (EZ), and inner plexiform layer (IPL) at baseline and at 1, 3, and 6 months. The foveal center of the EZ and IPL was marked in the choroid en face image. The choroidal images were overlapped to match the vasculature in each patient, and the postoperative displacement of the foveal center was compared to baseline.

RESULTS:

The center of the EZ and IPL was displaced significantly toward the disc during the first 3 months. The mean horizontal displacement at 1, 3, and 6 months was 52.7 μm, 112.5 μm, and 115.4 μm, respectively, for the EZ and 75.2 μm, 117.1 μm, and 136.5 μm, respectively, for the IPL. The location of the foveal center was significantly correlated between the EZ and the IPL (
P
≤ .016).

CONCLUSIONS:
The fovea was displaced nasally and slightly inferiorly after removal of the ILM. The displacement of the photoreceptor and inner retinal layers was concurrent.

Clinical Characteristics of Patients With CRVO in One Eye With Subsequent RVO in The Fellow Eye: A Retrospective Observational Study
Authors: Chan Melissa Mei Hsia , Thomas Akshay S. , Yoon Stephen P. , Leitner Diana , Fekrat Sharon 
Published: July 2019

BACKGROUND AND OBJECTIVE:
To compare risk factors in patients with a central retinal vein occlusion (CRVO) in the first eye and a subsequent retinal vein occlusion (RVO) in the fellow eye versus those with only unilateral CRVO.

PATIENTS AND METHODS:
Records of patients who presented to the Duke Eye Center with unilateral CRVO were evaluated. Logistic regression models were performed to identify potential covariates of subsequent development of RVO in the fellow eye.

RESULTS:

Of the 287 patients with CRVO in one eye, 31 (10.8%) developed an RVO in the fellow eye during a mean ± standard deviation follow-up of 36.7 months ± 38.86 months. The conversion rate of unilateral-to-bilateral RVO was 3.4% per year. Several comorbidities were observed to be unique to 25.8% of patients with bilateral RVO. Patients who used oral pentoxifylline (
P
= .008) or those who had an ischemic CRVO in the first eye (
P
= .001) were less likely to develop an RVO in the fellow eye.

CONCLUSION:
This information may be used to develop a predictive model to assess the risk of developing bilateral RVO in patients with unilateral CRVO.

Colistin-resistant microorganisms and cystic fibrosis: microbiological surveillance in an Italian Children’s Hospital
Authors: Montemari Anna Lisa , Tuccio Guarna Assanti Vanessa , Linardos Giulia , Di Bonaventura Giovanni , Ricciotti Gabriella , Fiscarelli Ersilia Vita 
Published: July 2019

Several advances in the medical field are often dependent on the ability to fight infections with the use of antibiotics, including joint replacements, organ transplants, and cancer therapy. The capacity of the bacteria to adapt to and escape from the mechanisms of action of antibiotics makes the antimicrobial resistance a serious public health problem worldwide. Polymyxin E colistin has rarely been used because of its nephrotoxicity and neurotoxicity. More recently, the emergence of multi-drug resistant bacteria as carbapenem-resistant Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa and the re-evaluation of its pharmacokinetic properties have led to a resurgence of colistin as a treatment option, contributing to select resistant strains. Investigating the phenomenon of colistin-resistance in gram-negative bacteria, especially P. aeruginosa, is now mandatory, particularly after identification of a plasmid-mediated mechanism for the resistance to colistin (mcr) in Enterobacteriaceae strains, a mechanism transferable to other species. In this study, we investigated colistin-resistance in gram-negative bacteria isolated from respiratory secretions of cystic fibrosis patients in follow-up at Children’s Hospital Bambino Gesù of Rome.

Published: July 2019

Aims:Since the six-tier Milan salivary gland classification has been introduced, there are very limited studies in literature reporting the risk stratification of the Milan classification.Methods:We retrospectively classified a total of 285 salivary gland cytology cases into Milan reporting categories; there were 23 (8.1%) nondiagnostic, 48 (16.8%) nonneoplastic, 19 (6.7%) atypia of undetermined significance (AUS), 138 (48.4%) benign neoplasm, 13 (4.6%) neoplasm of uncertain malignant potential (NUMP), 8 (2.8%) suspicious for malignancy, and 36 (12.6%) malignant. Almost 110 cases (38.6%) had surgical follow-up resections.Results:The overall risk for malignancy (ROM) was 12.5% for AUS, 3.2% for benign neoplasm, 72.7% for NUMP, and 100% for the suspicious for malignancy and malignant. The ROM for nondiagnostic and nonneoplastic categories was not representative due to limited follow-up resections. The salivary cytology had sensitivity, specificity, positive predictive value, and negative predictive value of 93.0%, 100%, 100%, and 46.2% for neoplasm and 82.3%, 95.8%, 90.3%, and 92.0% for malignant.Conclusion:Our study supports the adaptation of the six-tier Milan classification for reporting salivary gland cytology, as well as emphasizing the utility of the NUMP category.

The case of Ru, one of the traditional Korean building types, is introduced as a representative example; how its concept has been defined, changed, and forgotten in Korean culture. The importance of having a correct understanding of how cognition is composed of different types of experiences of cultural heritage is further explained. In this context, the importance of semantic mode and pictorial mode classified by Husserl is argued as the most powerful medium in human cognition based on phenomenological analysis. In this respect, the important role of Virtual Reality (VR) was highlighted. Considering the pace of recent technology and researches, breaking the barrier between experiencing the physical object and the VR may be a matter of time. Phenomenological classification of cultural heritage, which was designed for explaining all the types of cultural heritage, is introduced. The importance of developing a valid VR model and its role in cultural studies is emphasized via the phenomenological classification of cultural heritage. Finally, the balance of the inductive and deductive approach in a cultural study is suggested for more prolific and balanced achievements.</div><div data-canvas-width="408.0393972989316"> </div><div data-canvas-width="408.0393972989316"><p>Highlights:</p><ul><li>This article provides the philosophical background of the importance of visible cultural heritage based on the phenomenological point of view.</li><li>Significant impact on social members’ cognition of the visible cultural heritage is discussed in the case of the traditional Korean building.</li><li>In this respect, the important role of Virtual Reality technology is highlighted.</li></ul><p> </p></div>
El complejo termal monumental de la ciudad romana de Valeria: propuesta de reconstrucción virtual de sus ambientes fríos a la luz de los hallazgos arqueológicos.
Authors: Atienza Fuente Javier 
Published: July 2019

<p>The archaeological excavations carried out since 2014 at the Valeria site (Cuenca, Spain) have exhumed the remains of a thermal building built at the beginning of the 1st century A.D. The state of conservation is exceptionally good, with a height of walls that exceeds 3 m. This circumstance is due to the fact that the area in which the building is located was abandoned at the end of the 3rd century A.C. and its architectural structures were not subject of looting of construction materials. Archaeological excavations have exhumed the structures belonging to two different rooms: a western room, the frigidarium or cold room, and an oriental room paved with polychrome and geometric mosaics. The frigidarium, excavated almost entirely, has, on the western side, a natatio or indoor pool with a series of steps or benches attached to the northern and southern flanks. The excavation of these rooms has recovered about a thousand marble pieces of different typologies and provenances that were part of both the paving and parietal coatings, as well as abundant remains of mosaics and wall paintings that show the decorative richness of this space. The presence of glazed windows has also been proven due to the recovery of numerous fragments of glass, some of them still with remnants of lead. For all these results, a virtual reconstruction of the frigidarium is proposed, counting as base data with the conclusions derived from the study of the elements conserved in situ and those recovered in a controlled archaeological context. For the realization of the virtual recreation have been used textures, tonalities and decorative motifs taken from the archaeological remains.</p>

Published: July 2019

<p class="VARAbstract">This contribution shows the comparison, investigation, and implementation of different access strategies on multimodal data. The first part of the research is structured as a theoretical part opposing and explaining the terms of conventional access, virtual archival access, and virtual museums while additionally referencing related work. Especially, issues that still persist in repositories like the ambiguity or missing of metadata is pointed out. The second part explains the practical implementation of a workflow from a large image repository to various four-dimensional applications. Mainly, the filtering of images and in the following, the orientation of images is explained. Selection of the relevant images is partly done manually but also with the use of deep convolutional neural networks for image classification. In the following, photogrammetric methods are used for finding the relative orientation between image pairs in a projective frame. For this purpose, an adapted Structure from Motion (SfM) workflow is presented, in which the step of feature detection and matching is replaced by the Radiant-Invariant Feature Transform (RIFT) and Matching On Demand with View Synthesis (MODS). Both methods have been evaluated on a benchmark dataset and performed superior than other approaches. Subsequently, the oriented images are placed interactively and in the future automatically in a 4D browser application showing images, maps, and building models Further usage scenarios are presented in several Virtual Reality (VR) and Augmented Reality (AR) applications. The new representation of the archival data enables spatial and temporal browsing of repositories allowing the research of innovative perspectives and the uncovering of historical details.</p><p>Highlights:</p><ul><li>Strategies for a completely automated workflow from image repositories to four-dimensional (4D) access approaches.</li><li>The orientation of historical images using adapted and evaluated feature matching methods.</li><li>4D access methods for historical images and 3D models using web technologies and Virtual Reality (VR)/Augmented Reality (AR).</li></ul><p> </p>

Published: July 2019

A evapotranspiração (ET) exerce grande relevância no arrefecimento da temperatura do ar e contribui com o equilíbrio climático em área urbana. Entretanto, o conhecimento das taxas de ET voltados para esta finalidade apresentam-se limitados no campo da pesquisa. Diante disto, esse trabalho objetivou estimar a evapotranspiração na cidade do Recife - PE, visando analisar as diferenças intraurbanas nos diversos tipos de coberturas. Foram utilizadas seis imagens digitais do sensor TM - Landsat 5 referente à órbita 214 e pontos 65, 66. A densidade dos fluxos de calor sensível, e calor latente foram calculados com base no algoritmo SEBAL (Surface Energy Balance Algorithm for Land). Os resultados encontrados na ET estimada apresentaram-se coerentes quando comparados com os valores obtidos pelo método da FAO-Penman-Monteith, com erros absolutos entre 0,18 e 1,23 mm d-1, mínimo e máximo respectivamente e média de 0,86 mm d-1. As maiores taxas evapotranspirativas foram encontradas nas unidades de conservação e corpos hídricos entre 5,0 e 6,0 mm d-1, aproximadamente, enquanto nas superfícies com intenso adensamento construtivo valores próximos de 1,0 mm d-1. A metodologia utilizada representou de forma consistente os diversos tipos de coberturas, podendo promover um avanço significativo no monitoramento do clima urbano.
Agricultura orgánica, maíz criollo y extensión rural: percepciones de profesionales salvadoreños
Authors: Ayala Durán Carlos , Dabdab Waquil Paulo 
Published: July 2019

El presente artículo tiene como objetivo realizar un análisis exploratorio y cualitativo sobre las percepciones de extensionistas rurales públicos salvadoreños en relación a la agricultura orgánica y a la producción de maíz utilizando semilla criolla. Para tal fin, fueron encuestados todos los extensionistas públicos del Centro Nacional de Tecnología Agropecuaria y Forestal (CENTA) laborando en los departamentos de La Libertad y Sonsonate (N=28). Los resultados muestran que los extensionistas encuestados consideran a la agricultura convencional como más lucrativa y menos amigable con el medio ambiente, en contraposición a la agricultura orgánica. De la misma forma, estos profesionales del sector público consideran al maíz criollo en términos generales como menos productivo y lucrativo que el maíz híbrido, pese a que el primero es visto como mejor adaptado a las condiciones ambientales y climáticas del país.
