Small indeterminate superficial soft tissue masses: relationship between depth and histological grade
Authors: Khoo Michael , Pressney Ian , Gerrand Craig , Saifuddin Asif
Published: February 2020

Objective:

To determine whether the location of a small, indeterminate soft tissue mass within the subcutaneous compartment is related to its histological grade.

Methods:

All Sarcoma Service referrals over a 12 month period of small (<3 cm) superficial soft tissue masses, indeterminate by MRI evaluation which subsequently underwent primary excision biopsy were included. Lesions were categorised by their anatomical location in the subcutaneous compartment. Histopathological diagnoses were categorized according to12 WHO 2013. χ2 statistical analysis was performed to determine the relationship between lesion depth and histological grade.

Results:

The study included 43 patients, mean age 42 years (range 15–71 years). Within the subcutaneous compartment, 16 lesions were categorized as superficial, 9 lesions central and 18 lesions deep, of which 9 were non-neoplastic, 29 benign, 1 intermediate-grade and 4 malignant. Location in the deep aspect of the subcutaneous compartment was associated with a higher risk of intermediate or malignant histology (p = 0.02).

Conclusion:

The location of a small, indeterminate soft tissue mass within the subcutaneous compartment may be an indicator of histological aggressiveness. Lesions in the deep subcutaneous compartment are more likely to be intermediate-grade/malignant lesions. Therefore, if considering excision biopsy as definitive treatment, a wider margin may be appropriate.

Advances in knowledge:

Small, indeterminate soft tissue masses can be aggressive and the anatomical depth within the subcutaneous tissue may be a potential indicator of histological aggressiveness.

Authors: Μπάρμπας Γιώργος Συμεών , Τρυποπούλου Ουρανία
Published: February 2020

Η ομάδα των συνομηλίκων επηρεάζει τη διαμόρφωση της κοινωνικής ταυτότητας του νέου ανθρώπου. Στην προσχολική ηλικία, η κουλτούρα των συνομηλίκων εκδηλώνεται κυρίως στο ελεύθερο παιχνίδι, όπου τα παιδιά αρχίζουν να δρουν συλλογικά, να μοιράζονται, να διαμορφώνουν φιλικές σχέσεις και τις δικές τους ρουτίνες. Τα παιδιά με νοητική ανεπάρκεια έχουν δυσκολία να ενταχθούν στην ομάδα των συνομηλίκων, λόγω των γνωστικών περιορισμών και της απουσίας ανάλογων κοινωνικών εμπειριών.Η υπόθεση της έρευνας ήταν ότι αν ένας μαθητής με νοητική ανεπάρκεια αποκτήσει τη δυνατότητα ανταπόκρισης στις απαιτήσεις του συλλογικού παιχνιδιού των συνομηλίκων, τότε αναμένεται να ενισχυθεί η αποδοχή του από αυτούς. Το πρόγραμμα υλοποιήθηκε σε μαθητή με νοητική ανεπάρκεια που φοιτούσε σε τμήμα ένταξης νηπιαγωγείου. Από την επεξεργασία των δεδομένων προέκυψε ότι ο μαθητής βελτίωσε τις δεξιότητές του στην ανταπόκριση στους κανόνες του παιχνιδιού, στις απαιτούμενες δεξιότητες και μείωσε τις αρνητικές συμπεριφορές μέσα στο παιχνίδι, γεγονός που ενίσχυσε την αποδοχή από τους συμμαθητές του.

Authors: Δημοπούλου Ιωάννα Δημήτριος , Φρούντα Μαρία
Published: February 2020

Σκοπός της παρούσας εργασίας είναι η διερεύνηση των νοητικών αναπαραστάσεων των μαθητών της ΣΤ΄ τάξης δημοτικού σχετικά με την έννοια του κυττάρου. Συγκεκριμένα, στόχος είναι να διερευνηθεί αν οι μαθητές αντιλαμβάνονται το κύτταρο ως δομική  μονάδα όλων των οργανισμών μετά από τη διδασκαλία του αντίστοιχου κεφαλαίου στο μάθημα «Φυσικά – Ερευνώ και Ανακαλύπτω». Για τον σκοπό αυτό, διεξήχθη έρευνα τον Απρίλιο του 2017 σε δύο δημόσια δημοτικά σχολεία. Το δείγμα της έρευνας αποτέλεσαν 90 μαθητές που είχαν διδαχθεί την αντίστοιχη ενότητα 4 μήνες πριν. Οι μαθητές συμπλήρωσαν ερωτηματολόγιο, αποτελούμενο από ερωτήσεις κλειστού και ανοιχτού τύπου. Τα αποτελέσματα μετά την ανάλυση των δεδομένων, έδειξαν ότι η πλειονότητα των μαθητών παρουσιάζει αδυναμία κατανόησης του κυττάρου ως δομικής μονάδας όλων των ζωντανών οργανισμών. Επιπλέον, οι μαθητές δυσκολεύονται να αντιληφθούν ότι ένα κύτταρο μπορεί να υπάρχει αυτόνομα ως μονοκύτταρος οργανισμός. Τέλος, έγινε σύγκριση των ευρημάτων της εν λόγω έρευνας με ανάλογα ευρήματα άλλων σχετικών ερευνών.

Published: February 2020

Οι κοινωνικές συμπεριφορές που εμφανίζονται στο σχολικό περιβάλλον μπορούν να επηρεάσουν τα μαθησιακά αποτελέσματα. Η παρούσα έρευνα εξετάζει εάν οι αντιλήψεις των παιδιών για τη σχέση τους με τους συμμαθητές και τους εκπαιδευτικούς στο σχολείο σχετίζονται με τις πεποιθήσεις τους για τα κίνητρα μάθησης. Επιπλέον, εξετάζονται διαφορές στις παραπάνω μεταβλητές μεταξύ παιδιών δημοτικού σχολείου και γυμνασίου. Συγκεκριμένα, αξιολογήθηκαν οι αντιλήψεις των παιδιών για το βαθμό στον οποίο οι συμμαθητές και οι εκπαιδευτικοί αναγνωρίζονται ως πηγές ψυχο-συναισθηματικής ασφάλειας στο χώρο του σχολείου, με βάση δύο ποιοτικά γνωρίσματα διαπροσωπικών σχέσεων: την αμοιβαία εμπιστοσύνη/ποιότητα στην επικοινωνία και την αποξένωση. Τα γενικά κίνητρα των παιδιών για μάθηση και σχολικές επιδόσεις, αξιολογήθηκαν με ερωτήσεις που αφορούσαν στο βαθμό προσήλωσης στα μαθήματα, τις προσδοκίες στη διαδικασία της μάθησης και τη συναισθηματική αποφασιστικότητα για διατήρηση καλών σχολικών επιδόσεων. Τριακόσιοι εξήντα μαθητές από 4 δημόσια δημοτικά σχολεία και γυμνάσια του νομού Αττικής (μέση ηλικία = 10,49 έτη, τ.α.= 0,50, 51,1% αγόρια) συμμετείχαν στην έρευνα. Τα αποτελέσματα έδειξαν ότι η αντιλαμβανόμενη αμοιβαία εμπιστοσύνη/ποιοτική επικοινωνία στη σχέση των παιδιών με τους εκπαιδευτικούς και τους συμμαθητές τους αποτελούν σημαντικούς προβλεπτικούς παράγοντες θετικών πεποιθήσεων για τα κίνητρα μάθησης στα παιδιά. Αντίθετα, η αντιλαμβανόμενη αποξένωση στις διαπροσωπικές σχέσεις στη σχολική τάξη, βρέθηκε να ασκεί σημαντική αρνητική επίδραση στις πεποιθήσεις κινήτρων μάθησης. Τα κίνητρα μάθησης φαίνεται να φθίνουν στους μαθητές του γυμνασίου. Επιπλέον, βρέθηκαν σημαντικές διαφορές στην αντιλαμβανόμενη σχέση εκπαιδευτικού-μαθητή, μεταξύ μαθητών δημοτικού και γυμνασίου, με τα μικρότερα παιδιά να δηλώνουν ότι εμπιστεύονται και επικοινωνούν καλύτερα με τους εκπαιδευτικούς τους.
Visualize omics data on networks with Omics Visualizer, a Cytoscape App
Authors: Legeay Marc , Doncheva Nadezhda T. , Morris John H. , Jensen Lars Juhl
Published: February 2020

Cytoscape is an open-source software used to analyze and visualize biological networks. In addition to being able to import networks from a variety of sources, Cytoscape allows users to import tabular node data and visualize it onto networks. Unfortunately, such data tables can only contain one row of data per node, whereas omics data often have multiple rows for the same gene or protein, representing different post-translational modification sites, peptides, splice isoforms, or conditions. Here, we present a new app, Omics Visualizer, that allows users to import data tables with several rows referring to the same node, connect them to one or more networks, and visualize the connected data onto networks. Omics Visualizer uses the Cytoscape enhancedGraphics app to show the data either in the nodes (pie visualization) or around the nodes (donut visualization), where the colors of the slices represent the imported values. If the user does not provide a network, the app can retrieve one from the STRING database using the Cytoscape stringApp. The Omics Visualizer app is freely available at https://apps.cytoscape.org/apps/omicsvisualizer.

A 13 J direct-liquid-cooled solid-state disk laser with an unstable cavity is developed and demonstrated in this paper. The output energy of the resonant cavity is first analyzed according to the gain level in a stable cavity. At the optimum gain level, a magnification of 1.3 in the unstable cavity is achieved. Experimentally, a concave-convex mirror is used as the cavity mirror. At a magnification of 1.3, a repetition frequency of 100 Hz, and a pulse width of 350 µs, a single-pulse energy output of 13.2 J is obtained, corresponding to an optical-optical efficiency of 22% and a slope efficiency of 27.6%.

Predicting resolution and image quality in RESOLFT and other point scanning microscopes [Invited]
Authors: Bodén Andreas , Casas Moreno Xavier , Cooper Benjamin K. , York Andrew G. , Testa Ilaria
Published: February 2020

The performance of fluorescence microscopy and nanoscopy is often discussed by the effective point spread function and the optical transfer function. However, due to the complexity of the fluorophore properties such as photobleaching or other forms of photoswitching, which introduce a variance in photon emission, it is not trivial to choose optimal imaging parameters and to predict the spatial resolution. In this paper, we analytically derive a theoretical framework for estimating the achievable resolution of a microscope depending on parameters such as photoswitching, labeling densities, exposure time and sampling. We developed a numerical simulation software to analyze the impact of reversibly switchable probes in RESOLFT imaging.
Design of seamlessly and limitlessly expandable OXC and verification tests on its versatile applicability
Authors: Hashimoto Ryota , Mori Yojiro , Hasegawa Hirioshi , Sato Ken-ichi
Published: February 2020

We propose an extremely cost-effective optical-cross-connect (OXC) architecture that allows hitless port-count expansion with virtually no limit to meet incremental traffic growth at minimum cost. This is enabled by a new interconnection scheme of optical splitters and wavelength-selective switches (WSSs) in the express-switch part and that of transponder banks in the add/drop parts. The benefit is offset by slight constraint on routing flexibility, which is minimized with a newly developed interconnection algorithm. Extensive computer simulations are carried out to verify that the proposed OXC retains satisfactory routing capability without notable penalty even though smaller-degree WSSs (

) are utilized: it is compared with present fixed-port-count OXCs using larger-degree WSSs (

), which have no hitless extension capability. The proposed OXC with the proposed algorithm can drastically reduce OXC hardware cost. We analyze node-design parameters in terms of the routing performances of the OXC and search for the appropriate values. The effects of traffic churn ratio during network expansion and the geographic traffic distribution are investigated. The results verify the effectiveness and robustness of the OXC architecture and the expansion scheme; the number of WSSs needed and the necessary component WSS port count can be greatly reduced while the resultant link fiber increment is marginal (1%–5%), compared with the ideal OXC without any routing restriction.
Multimode silicon photonic waveguide corner-bend
Authors: Wang Yi , Dai Daoxin
Published: February 2020

An ultra-sharp multimode waveguide bend (MWB) based on a multimode waveguide corner-bend (MWCB) is proposed and realized. With the present MWCB, total internal reflection (TIR) happens and the light propagation direction of all the mode-channels can be modified with low excess losses (ELs) and low inter-mode crosstalk (CT) in the optical communication bands from 1260 nm to 1680 nm. For the MWCB designed for the TE0 and TE1 modes, the ELs are less than 0.18 dB and the inter-mode CTs are less than −36 dB in the wavelength range of 1260-1680 nm. The measurement results show the fabricated MWCB works very well as predicted by the theory. It is very flexible to extend the present MWCB for more mode-channels by simply adjusting the core width. For example, the MWCB designed with a 35 µm-wide core has an EL less than 0.54 dB and inter-mode CT less than −24 dB for the ten TE-polarization modes (i.e., TE0∼TE9) in the wavelength-band of 1260-1680 nm. For the present MWCB, the fabrication is also very convenient because no tiny nano-structure and no additional fabrication steps are needed. It also shows that the present MWCB is not sensitive to the sidewall angles even when the angle is up to 8°. The proposed MWCB is promising for multimode silicon photonics because of the simple structure, easy design, easy fabrication as well as excellent performances in an ultra-broad wavelength-band.
Precise 3D particle localization over large axial ranges using secondary astigmatism
Authors: Zhou Yongzhuang , Carles Guillem
Published: February 2020

We propose an analytical pupil phase function employing cropped secondary astigmatism for extended-depth nanoscale 3D-localization microscopy. The function provides high localization precision in all three dimensions, which can be maintained over extended axial ranges, customizable up to two orders of magnitude relative to the conventional, diffraction-limited imaging. This enables, for example, capturing nanoscale dynamics within a whole cell. The flexibility and simplicity in the implementation of the proposed phase function make its adoption in localization-based microscopy attractive. We demonstrate and validate its application to real-time imaging of 3D fluid flow over a depth of 40 µm with a numerical aperture of 0.8.

Authors: Hu Lien , Zheng Chuantao , Zhang Yu , Zheng Jie , Wang Yiding , Tittel Frank K.
Published: February 2020

To overcome the limitations of size, optical alignment, and integration into photonic circuits in previous light-induced thermoelastic spectroscopy (LITES) using free-space optics, a compact all-fiber LITES was proposed for gas sensing. A hollow-core photonic crystal fiber was employed as a waveguide and a microcapillary gas cell simultaneously. A single-mode fiber (SMF) tip was employed to guide light on the quartz tuning fork (QTF) surface. The distance between the SMF tip and the QTF, and the light excitation position on the QTF’s surface were optimized experimentally. The detection performance of the all-fiber LITES was evaluated by detecting methane, and a normalized noise equivalent absorption coefficient of

Published: February 2020

In this Letter, we investigate the tight focusing of a second-order cylindrical vector beam by a hyperbolic secant gradient index lens with a thickness of 10 µm, a radius of 9.43 µm, and a refractive index on the axis of 3.47 (silicon). It is shown that the lens forms the reverse energy flow near its shadow surface. Moreover, it was obtained that the spherical hole in the center of the shadow plane with a diameter of 0.3 µm allows us to localize the direct energy flow inside the lens material and with the reverse energy flow in an area of free space.
Fully reversible spectral compression of arbitrary pulsed data signals
Authors: Romero Cortés Luis , Maram Reza , Azaña José
Published: February 2020

Data signals consisting of arbitrarily modulated sequences of pulses are extensively used for processing and communication applications. The spectral extent of such signals is determined by the bandwidth of the individual pulses in the sequence, which imposes a fundamental limit to the maximum amount of information that can be transmitted or processed per time period. In this work, we propose and experimentally demonstrate that the frequency spectrum occupied by a data-modulated pulse sequence can be significantly compressed to well below the individual pulse bandwidth while still maintaining the temporal duration of the pulses in the sequence and without losing any of the information carried by the signal. The proposed method involves fully reversible linear transformations of the data signal along the time and frequency domains. We demonstrate successful pulse-shape-preserving spectral compression and subsequent full waveform and information recovery of a

Published: February 2020

Acute cholecystitis is one of the main causes of medical care in emergencies around the world. It is defined as inflammation of the gallbladder caused mainly by obstruction of the cystic duct by stones. In a small number of patients, the inflammatory process can develop in the absence of stones, receiving the name of alitiásic cholecystitis, having a faster evolution and often evolving with perforation. Acute alitiásic cholecystitis (AAC) corresponds to 15% of cases of acute cholecystitis and mainly affects patients in severe condition and with comorbidities. Its pathophysiology is still little known, but ischemia and stasis are identified as the main causes. Its high mortality is related to biliary peritonitis due to coleperitoneum. A patient admitted to the emergency department of Hospital Regional do Cariri with acute inflammatory abdomen was diagnosed with coleperitoneum, due to AAC complication, and underwent urgent laparoscopic cholecystectomy, with good clinical evolution in the postoperative period and early return to his activities. Keywords: acute cholecystitis, coleperitoneum, cholecystectomy

Published: February 2020

O presente trabalho apresenta uma discussão sobre a temática alfabetização e letramento. Fundamenta-se na perspectiva da teoria construtivista e do alfabetizar letrando onde se aproxima do processo natural do desenvolvimento psicológico da criança.  Analisa e faz uma reflexão teórica em torno das práticas pedagógicas dos professores. Amplia essa reflexão com recomendações a respeito do alfabetizar na perspectiva do letramento. A temática busca investigar diferentes concepções baseadas em discussões de diferentes autores (SOARES, 2003; KRAMER, 1998; FRANCHI, 2012; FERREIRO, 2010) sobre práticas de alfabetização. Isto porque com o desenvolvimento da sociedade contemporânea apenas o acesso ao mecanismo da escrita não é suficiente para que o indivíduo participe da sociedade; é preciso, além de ser alfabetizado, saber fazer uso da leitura e da escrita nos contextos sociais em que está inserido.
A Gastronomia e o Sagrado: O alimento que satisfaz o corpo e o espírito / Gastronomy and the Sacred: Food that satisfies body and spirit
Authors: Souza Izabel Cristina Francisco , Paradella Cássia Lourdes
Published: February 2020

O presente artigo é parte do corpus da pesquisa de dissertação de mestrado em Ciências das Religiões, objetivando compreender em que medida, no Candomblé, a alimentação entendida como comida de Santo pode representar significados e configurar-se como elemento de identidade e conexão com o sagrado. Uma vez que o processo alimentar, no campo religioso, especialmente no Candomblé, tem como base diretiva, as doutrinas/dogmas que indicam os alimentos como apropriados ou inapropriados. Para tanto, analisar as funções simbólicas da alimentação, na perspectiva do consumo e oferenda da comida de Santo e as funções simbólicas da linguagem, revela mais do que a necessidade orgânica; tem a ver com a cultura, com as crenças, a constituição de valores, de restrições, ritos e tabus; além de dar sentido à existência humana. O simbolismo agrega seguimentos tanto concretos, como abstratos, relacionados a valores morais, poder, conhecimento e sínteses. É nesse sentido que se pretendeu analisar a criação dos símbolos a partir de seu caráter religioso. Especialmente no que tange a particularidades culturais, mudanças histórico-sociais, devoção, e simbolismos ligados ao processo alimentar na prática religiosa do Candomblé.
A Contribuição Familiar no Processo Terapêutico da Criança: Um Estudo Bibliográfico / Family Contribution to the Child's Therapeutic Process: A Bibliographic Study
Authors: Callou Ticiane Kelly Bento Machado , Calou Antonio Leonardo Figueiredo
Published: February 2020

O presente texto vem resgatar a importância da participação da família no processo terapêutico da criança, compreendendo que este é um processo que envolve não apenas os aspectos individuais dessa como sujeito social, mas toda a sua história, e dessa forma a participação pregressa da família torna-se primordial. Objetiva-se então, identificar os aspectos relevantes que a família proporciona ao participar do processo terapêutico junto às crianças. Diante disso, o estudo destaca sobre a relação entre família, criança e o processo terapêutico, enfatizando os fatores que levam a inserção das crianças na psicoterapia, a relação entre a família e a criança, e de que forma a família deve estar inserida nesse processo para que a psicoterapia avance. A metodologia da pesquisa foi composta por um estudo de método qualitativo, por permitir uma aproximação mais abrangente do pesquisador com a realidade estudada; caracteriza-se de natureza bibliográfica por ter resultados alcançados mediante a análise de fontes literárias pesquisadas em plataformas como o Scielo, Lílacs e Pepsic, realizadas entre os meses de janeiro e março de 2019. Os resultados obtidos apontam que as famílias não são mais coadjuvantes no processo terapêutico das crianças, e sim protagonistas, ou seja, os avanços terapêuticos tornam-se possíveis e progridem quando a família se enxerga como parte desse processo, contribuindo diretamente para que os problemas sejam superados e a criança então, sentir-se acolhida. Assim, os estudos aqui revisados, apontam que a participação da família na psicoterapia resulta em aspectos positivos que influenciam também no fortalecimento dos membros, acarretando por sua vez, múltiplos resultados favoráveis a evolução de quadros clínicos.

Authors: Nurmansyah Ihsan
Published: February 2020

The advancement of knowledge and technology presents its own challenges to Muslims’ socio-religious life. One of them is the progress in the medical field regarding organ transplants of animals to humans. Religious problems arise when animals used in transplantation are those that are deemed unlawful (haram) by Islamic texts. On the one hand, organ transplants provide benefits for humanity, but on the other, donors of transplants are unlawful animals. This paper examines the lawfulness of using the body parts of pigs, whose unlawfulness is stated in many verses of the Qur'an. This study uses a contextual interpretation introduced by Abdullah Saeed. Based on contextual considerations, this study concludes that QS. al-Baqarah: 173, QS. al-Maidah: 3, QS. al-Anam: 145 and QS. an-Nahl: 115 prohibit pork for consumption. The commentators of the Qur’an have differences of opinion concerning the uses of pigs beyond consumption. This paper suggests that using the body parts of pigs is legitimate. This is reinforced by QS. al-Baqarah: 173 which explains an emergency context. Pigs do not belong to the category of najis ‘aini, which allows it to be transplanted into the human body. However, some conditions need to be fulfilled for transplantation. The transplantation permitted if  these is not rise risk of further to harm and a recommendation from the doctor about the patient's condition.

Local web buckling is one of the most common failure modes for coped steel beams. While several studies have been undertaken focusing on the behavior of top-flange/single-coped beams, double-coped beams have received little attention. To fill this knowledge gap, this paper presents experimental and numerical studies on local web buckling behavior of double-coped steel beams. Five full-scale tests were conducted, and the main test parameters were cope length and cope depth. Local web buckling was observed as the main failure mode for all of the five specimens, and the buckling resistance was found to decrease with increasing cope length and cope depth. A FE study was subsequently conducted, where the response of the FE models agreed well with the test results, especially in terms of buckling mode and buckling resistance. The test and FE results were compared with those predicted by an existing design approach. The design results were found to be quite conservative, and hence further investigation may be required to achieve a more accurate design approach. procedure and faster computational efficiency than the Modal Pushover Analysis (MPA) procedure for irregular bridges.
FLY ASH AND BAGASSE FIBER INFLUENCES ON MECHANICAL PROPERTIES OF GREEN HYBRID FIBER-REINFORCED CEMENTITIOUS COMPOSITES
Authors: Tian He , Zhang Y. X.
Published: February 2020

In this paper, a new green fiber-reinforced cementitious composite containing high volume fly ash and hybrid steel and bagasse fibers is developed. Eco-friendly bagasse fibers from industrial waste and steel fibers are used to improve the mechanical behavior of the new composite, and high-volume fly ash is used to decrease the usage of cement in order to be more environmentally friendly. The influence of the fiber content and fly ash/cement ratio on the mechanical properties of the composite is investigated through the study of the mechanical properties of the new composite, such as compressive strength, modulus of elasticity, and modulus of rupture. It is found that compressive strength, Young's modulus of the composite, decreases with the increase of the fly ash/cement ratio and bagasse fiber content. However, the modulus of rupture of the composite increases firstly with bagasse fiber content, and decreases when bagasse fiber content reaches 3% by volume.

Published: February 2020

Asphalt plays a significant role in a pavement’s ability to withstand thermal and fatigue cracking that contributes to permanent deformation behavior. Temperature is a significant factor that affects asphalt binder and thus the performance and life span of the whole pavement. This paper presents research developing asphalt binder performance grade requirements, according to Superpave, suitable for different climatic conditions all over Egypt. Twenty one weather stations covering Egypt were selected, then after analysis their air temperature data was converted to pavement temperatures using LTPP and performance models. Finally, the converted pavement data were used to propose asphalt binder performance grades (PG) for the various regions of Egypt. The proposed grades range from PG52-10 to PG76-10 depending on the location, the applied model, and the degree of project reliability.
AN EXPLORATORY EVALUATION OF A NEW RISK-BASED INSPECTION SCHEME
Authors: Samasoni Jeff Clement , Olabode Bamidele Rotimi James
Published: February 2020

Government passes laws both through statute and regulation to protect people. The Building Act is one of such government regulation that obligatorily requires buildings be designed and constructed for safety, health, development, and the safeguarding of people from possible injury. In 2010, the New Zealand Government proposed a new control regime to streamline building proposal approval by introducing risk-based inspections, where inspection were circumvented in terms of risk for certain types of building works. Risk-based inspection is generally seen as accelerating the process of building approvals, therefore allowing contractors to manage their project time without a bottleneck of regulatory inspections. The study offers a preliminary evaluation of the effectiveness of this newly-introduced building inspection scheme. The larger study programme on which this paper is based gathered the perceptions of building control practitioners. Data was also collected through a questionnaire survey to homeowners/agents of completed homes. This could improve the institution of this new scheme. This paper puts this larger study into perspective for the New Zealand construction industry and academia. It finds that risk-based building inspections will likely accelerate the building process, but can only flourish if licenced building practitioners provide a quality product and stand by their work.
THE IMPORTANCE OF CONSTRUCTION LAW IN CIVIL AND STRUCTURAL ENGINEERING EDUCATION
Authors: Quapp Ulrike , Holschemacher Klaus
Published: February 2020

During the process of creating civil or structural engineering curriculums, the people in charge sometimes do not recognize the importance of including interdisciplinary subjects that are not directly related to civil or structural engineering fields, such as construction law. There are a variety of reasons for this. The first part of the paper provides an overview about curriculum’s creation processes at German universities. It describes the involved parties and the difficulties in finding a fair balance between the interests of all involved lecturers while observing the legal guidelines. The second part covers whether or not and to what extent construction law courses should be included in a civil or structural engineering program. It discusses the advantages and disadvantages of including construction law courses. The conclusion is that courses in construction law are necessary to ensure graduates’ employability and the qualification to work professionally. However, civil or structural engineering graduates do not have to become Construction Law experts—they only have to acknowledge the seriousness of a situation and to identify a legal problem. This enables the building industry to save money that otherwise might have been spent on unnecessary legal consulting.
MULTI-OBJECTIVE DECISION-MAKING TO SELECT MULTIPLE PROJECT DELIVERY METHODS FOR MULTI-PROJECT TRANSPORTATION SYSTEMS
Authors: Zeng Ziqiang , Minchin R. Edward , Ptschelinzew Lourdes , Zhang Yuanxin
Published: February 2020

This paper focuses on providing a methodology to optimize the selection of multiple project delivery methods for multi-project transportation systems under uncertainty. In contrast to previous studies, this paper considers that owners sometimes divide transportation projects into sub-projects that are constrained by construction sequence. The owners’ objectives are to minimize the total project cost and duration for the whole multi-project undertaking by selecting the most appropriate project delivery method for each sub-project. The complexity of this problem is the motivation for the development of a multi-objective decision making model that can help owners evaluate and choose the appropriate project delivery method for each sub-project. The model considers three fundamental project delivery methods, i.e., design–bid–build, design–build, and construction manager-as-general contractor. The project cost and duration of each sub-project when selecting different project delivery methods are estimated by experts employed and/or retained by the owner, and regarded as fuzzy variables. Furthermore, a fuzzy simulation-based multiple objective particle swarm optimization algorithm is developed to find feasible Pareto solutions. Results and analysis of a numerical example are presented to highlight the performance of the model.
LIMIT ANALYSIS UNDER LATERAL LOADS OF MASONRY VAULTS UPDATED BY Ω-WRAP
Authors: Anania Laura , D'agata Giuseppe
Published: February 2020

In this paper, the structural behavior under lateral load of a masonry-barrel vault, strengthened by new technology by applied Carbon-Fiber Reinforced Polymer (C-FRP), is discussed from both theoretical and experimental points of view. The C-FRP is applied such as to assume an Ω shape around a concrete core at the vault extrados. A theoretical prediction of ultimate strength was derived in agreement with observations during the experiments (e.g., masonry crushing, FRP rupture, debonding, sliding along the mortar joint). A lower-bound limit-analysis approach was developed that can handle the shear strength of each ideal section given by the Mohr-Coulomb friction law (for the mortar joint). It can also handle other non linear Italian Code relations (for CFRP Ω-Wrap reinforcement) at a given level of normal compressive stress resulting from the previous step.
DISPERSION OF WAVE FORCES ON CAISSON BREAKWATERS USING INTERLOCKING SYSTEMS

Published: February 2020

Interlocking caisson-type breakwaters have recently gained attention for enhancing the stability of the conventional breakwaters. In this study, the dispersion characteristics of wave forces using interlocking systems connecting the upper part of caissons with cables in the normal direction of breakwaters were investigated. Based upon numerical experiments, the higher wave forces are transmitted through the cable as the angle of incident wave increases, while the maximum allowable wave force was capable of being increased by sharing the wave forces with the adjacent caissons. It was also found that the larger the stiffness of the interlocking cable, the larger the wave-dispersion effect.
MECHANICAL PROPERTIES OF FLY ASH-BASED ALKALI-ACTIVATED CEMENT USING A STATISTICAL ANALYSIS TECHNIQUE
Authors: Lee Hyuk , Vimonsatit Vanissorn
Published: February 2020

This paper presents the mechanical properties of fly ash-based alkali-activated cement (AAC). A statistical analysis method was used to determine the effect of mix proportion parameters on the dry density and compressive strength of fly ash-based AAC pastes and mortars. For that purpose, sample mixtures were designed according to Taguchi’s experimental design method, i.e., in a L9 orthogonal array. Four factors were selected: “silica fume content” (SF), “sand to solid ratio” (s/c), “liquid to solid ratio” (l/s), and “superplasticiser content” (SP). The experimental results were analysed by using signal to noise for quality control of each mixture, and analysis of variance (ANOVA) was used to determine the significant effect on the compressive strength of fly ash-based AAC. Furthermore, a regression-analysis method was used to predict the compressive strength according to the variation of the four factors. Results indicated that silica fume is the most influencing parameter on compressive strength, which could be decreased by superplasticiser and l/s ratio. There is no significant effect of sand-to-cementitious ratio on compressive strength of fly ash-based AAC. The dry density decreases as the sand-to-cementitious ratio is decreased. The increasing l/s ratio and superplasticiser dosage could further decrease the dry density of fly ash-based AAC.
A STUDY OF GROUTING MATERIAL BLEEDING PROPERTIES FOR PRESTRESSED CONCRETE
Authors: Koh Kyung-Taek , Ryu Gum-Sung , Ahn Gi-Hong
Published: February 2020

This study investigates the workability, bleeding, and volumetric change of grout widely used in Korea for securing the quality of grout applied in prestressed concrete (PC) bridges. The results reveal that the workability satisfies all the criteria for the grout specified in Korea. It appears that bleeding increases by 5.7 to 6.7 times when the tendon is arranged, regardless of the quality of grout, and that the height and inclination of the grout sample significantly affect bleeding. Furthermore, the arrangements of tendons were seen to prevent expansion even in grout using expansive aluminum powder, but was also seen to let shrinkage occur with a significant increase in bleeding. The conclusion is that it is necessary to establish a new testing method and apply high-performance grout for securing the quality of the grout used in PC bridges.
SUPPLY CHAIN INTEGRATION BARRIERS IN CONSTRUCTION: VIEWS FROM TWO SOUTH AFRICAN PROJECTS
Authors: Emuze Fidelis , Smallwood John , Beetge Wynand
Published: February 2020

The fragmented state of the construction industry is a global phenomenon visible in South African construction. The number of parties to a construction project has been on the upward trend in recent times. This increase in the number of members of a typical construction supply chain is invariably accompanied by an increase in management complexity. To counter the pitfalls of such complexities, the discipline has witnessed the proliferation of supply chain management (SCM) concepts of which integration is a notable aspect. Based on a succinct conceptual framework that was derived from the construction SCM literature, this paper reports on barriers to supply chain integration. A questionnaire was distributed among the participants of two South African projects. The responses indicate that lack of integration is partly responsible for performance-related failures in the form of rework and defects. Moreover, poor payment mechanisms between contractors, their subcontractors, and suppliers tend to work against nurturing long-term relationships on a project and business basis. The conclusion is that there is major scope for promoting a collaborative working approach between supply chain partners in South African construction.
DECISION PRINCIPLES FOR ASCENT SUPPORTS IN BUILDING CONSTRUCTION
Authors: Schlagbauer Dieter , Hofstadler Christian , Ninaus Cornelia
Published: February 2020

Ladders are the ascent system most commonly used to scale up a building, due to the low initial costs compared to other ascent equipment. The insufficiency of this approach is shown in an economic comparison of ladders, stair towers, and scaffoldings with integrated ascent support. Based on empirical studies, cost data and the current state of scientific knowledge, the ascent support with the highest economic value can be determined by considering safety, cost, time, stress, physical stress and strain, and frequency of use. A survey evaluated vertical transport routes, the ascent systems ladders, stair towers, and scaffoldings with integrated ladders. The findings indicate that from an economic point of view, ladders should be used only on construction sites where less than 54 ascents were performed each day. This leads to the assumption that for typical construction sites, with at least 6 ascents per person per day and a site usage for a period longer than one week, the operation of ladders is uneconomical.
