Demand Driven Material Requirements Planning (DDMRP): A systematic review and classification
Authors: Azzamouri Ahlam , Baptiste Pierre , Dessevre Guillaume , Pellerin Robert 
Published: May 2021

Purpose: Demand Driven Material Requirements Planning (DDMRP) aims to deal with variability by adjusting inventory levels while maintaining, or even increasing, customer service levels. This approach bridges the push and pull approaches. Even though it first made its appearance in 2011, research in this field remains relatively limited. This paper aims to measure the spatiotemporal evolution of the DDMRP, its scope and context of implementation, and the research lines studied in that field in order to identify areas that still need to be addressed by future researchers.Design/methodology/approach: The systematic literature review approach adopted in this paper examines research dealing with the DDMRP approach published in different languages between 2009 and 2020. To-date papers focused on the performance analysis and comparison, what differentiates this study is the focus on the scientific evolution level of DDMRP, the parameters, and contexts that should be more studied.Findings: The results show that DDMRP is not yet a mature method and that the robustness of the approach still needs to be tested. More research is also required to determine scientifically some setting parameters, how the proposed DDMRP could be implemented in different industrial contexts with existing information systems.Originality/value: Based on the evolution analysis of DDMRP, this study outlines its current state of maturity and its different shortcomings under a broader vision to make this method more complete on the scientific and industrial level.

Este estudo investigou o efeito do treinamento pliométrico (TP) no salto vertical em atletas jovens de basquete. Participaram 39 atletas, divididos em dois grupos experimentais (masculino - GEM e feminino - GEF) e dois grupos controle (masculino - GCM e feminino - GCF). O aplicativo My Jump quantificou a altura do salto a partir do tempo de voo. Para análise dos dados utilizou-se anova de medidas repetidas, tamanho de efeito de Cohen (TE) e a inferência baseada na magnitude, com nível de significância (p≤ 0,05). Os resultados indicam que o GEM e GCM apresentaram melhoras significativas no countermovement jump (CMJ) e squart jump (SJ). O GEF e GCF apresentaram diferenças significativas no SJ com efeito de interação, no CMJ apenas o GEF apresentou melhoras com efeito de interação. No TE, o GEM apresentou maiores efeitos no CMJ e SJ quando comparado ao GCM, no GEF, o TE foi maior somente no CMJ em relação ao GCF. As respostas qualitativas mostraram que o TP é provavelmente benéfico no GEM, já no GEF, mostrou que é provavelmente benéfico no SJ e muito provavelmente benéfico no CMJ. Conclui-se que o TP promoveu efeitos positivos no GEM e GEF, tanto no CMJ quanto no SJ. Nos grupos controles, ambos obtiveram melhorias significativas no SJ, porém no CMJ, somente o GCM apresentou aumento. Ademais, os resultados foram maiores no GEM e GEF em comparação com o GCM e GCF. Assim, o TP é indicado para potencializar o salto vertical em atletas jovens de basquete.

Published: May 2021

Objective:
Comparing caries status and oral health behavior in rural and urban school children can reveal different etiological factors associated with dental caries, which will help in planning appropriate preventive program.

Materials and Methods:
The present longitudinal study was conducted among 7–9-year-old children, 200 each from randomly selected one urban and one rural school of Aligarh city. A preformed questionnaire was used to assess the oral health knowledge, attitude, and practice. Caries status was recorded using decayed, missing, and filled teeth (DMFT)/deft index. School health education was given to the same children of both the schools. These steps were repeated at 6 and 12 months.

Results:
By independent t-test, significant effect of dental health education was seen at 6 months (P = 0.029) and 12 (P = 0.000) months with respect to increase in knowledge score and similar significant promising results were seen for increased attitude and practice score at 6 months (P = 0.0039) and 12 months (P = 0.000) for rural group. Reduction in def score was statistically significant by Mann–Whitney U-test at 6 months (P = 0.04) and at 12 months (P = 0.03) for rural group.

Conclusion:
Planned health education given through lecture – live demonstration lead to reduction in the deft/DMFT score; change in the d/D component to either m/M or f/F respectively as the treatment need be; and progressive increase in the knowledge, attitude, and practice score.
The influence of the stress factor in the legal practice
Authors: Sandu Mihaela Luminita , Călin Mariana Floricica , Dragomir Rodica 
Published: May 2021

Along with well known sources, we observe, for the modern person, that the work environment is a stress source who can contribute to the individual life quality deterioration. Professional stress, like it’s called in the law literature, is the stress generated from activities of work place and from the environment in which those activities occur. This type of stress can generate a multitude of atypical manifestations in a person and can have different durations correlated with the stress factors intensity. Maintaining the effects of the stress factors for long period of time can favor the somatic illnesses or even the organic ones. The explicit recommendation of specialists is to identify the most significant stress factors at the work place then take appropriate action to eradicate their causes, or, when possible to limit their effects. The law is a liberal professional, serving justice. So it’s a fact that without it as part of the judicial system, justice cannot prevail in an effective manner. Even if it’s essential to the judicial system, the law is internal to a dramatic decorum, open to threats. We cannot question the high degree of professional stress that is laid upon the members of this practice, and even the young attorneys at the beginning of their careers, who just graduated and have high dreams and strive to excel professionally, are at risk. Regrettably, with the beginning of the practice their dreams slowly dissipate, in the existential void, because of the long wait at the courthouse and the disappointment that deciding parties (judges and prosecutors) of the justice scene are imposing and impedes upon the justice spirit of the young attorneys.

The surface energy balance in a cold and arid permafrost environment, Ladakh, Himalayas, India
Authors: Wani John Mohd , Thayyen Renoj J. , Ojha Chandra Shekhar Prasad , Gruber Stephan 
Published: May 2021

Abstract. Recent studies have shown the cold and arid trans-Himalayan region comprises
significant areas underlain by permafrost. While the information on the
permafrost characteristics of this region started emerging, the governing
energy regime is of particular interest. This paper presents the results of
a surface energy balance (SEB) study carried out in the upper Ganglass
catchment in the Ladakh region of India which feeds directly into the
Indus River. The point-scale SEB is estimated using the 1D mode of the
GEOtop model for the period of 1 September 2015 to 31 August 2017 at 4727 m a.s.l. elevation. The model is evaluated using field-monitored snow depth
variations (accumulation and melting), outgoing long-wave radiation and
near-surface ground temperatures and showed good agreement with the
respective simulated values. For the study period, the SEB characteristics
of the study site show that the net radiation (29.7 W m−2) was the
major component, followed by sensible heat flux (−15.6 W m−2), latent
heat flux (−11.2 W m−2) and ground heat flux (−0.5 W m−2). During
both years, the latent heat flux was highest in summer and lowest in winter,
whereas the sensible heat flux was highest in post-winter and gradually
decreased towards the pre-winter season. During the study period, snow cover
builds up starting around the last week of December, facilitating ground
cooling during almost 3 months (October to December), with sub-zero
temperatures down to −20 ∘C providing a favourable environment
for permafrost. It is observed that the Ladakh region has a very low
relative humidity in the range of 43 % compared to e.g.
∼70 % in the European Alps, resulting in lower incoming
long-wave radiation and strongly negative net long-wave radiation averaging
∼-90 W m−2 compared to −40 W m−2 in the European
Alps. Hence, land surfaces at high elevation in cold and arid regions could be
overall colder than the locations with higher relative humidity, such as the
European Alps. Further, it is found that high incoming short-wave
radiation during summer months in the region may be facilitating enhanced
cooling of wet valley bottom surfaces as a result of stronger evaporation.

Authors: Oprita Alexandru , Sevastre Ani-Simona 
Published: May 2021

Among all types of cancer encountered in women, breast cancer is the most prevalent, with the highest mortality rate. An increased survival rate is closely related to early diagnosis, the use of high performing screening methods and of selective and adequate treatments.
By using the nanotechnologies, the therapeutic effectiveness of the drugs may be improved by a controlled release of the active substances to the tumoral site. The aim of this review is to present the current state of knowledge and to mention the new treatment trends in breast cancer, focusing on a pharmaceutical form that, thanks to its advantages, is already used in the therapy of this disease – the polymeric micelles.
Several examples of anticancer agents loaded polymeric micelles are mentioned, illustrating the preparation methods and the current state of clinical studies in which polymeric micelles are used.

Empirical Legal Studies in the law school curricula: current situation in the Netherlands and the way forward
De groeiende aandacht voor Empirical Legal Studies (ELS) in Nederland roept vragen op over het onderwijs in empirisch-juridische vaardigheden in ons land. Er gebeurt al het nodige op dit vlak, maar een nauwkeurige inventarisatie van welke ELS-vakken reeds concreet worden aangeboden in Nederland ontbreekt. Een dergelijk overzicht zou het mogelijk maken dat opleidingen van elkaar leren en kennis en kunde uitwisselen in plaats van het wiel opnieuw uit te vinden. Daarom hebben wij een uitgebreide rondgang gemaakt langs de diverse opleidingen aan rechtenfaculteiten, om in kaart te brengen welke vakken met aandacht voor empirische methoden reeds in het reguliere rechtencurriculum worden aangeboden. In dit artikel rapporteren wij de resultaten van deze landelijke inventarisatie en werpen een blik op de toekomst in het licht van recente discussies en ontwikkelingen die verband houden met ELS in Nederland.

Published: May 2021

The aim of this research was to compare the service quality dimensions of a civil construction material technology laboratory according to the dimensions’ importance from the perspective of concrete specimen and ceramic brick breaking services customers. Multiple regression analyses were performed from the results of the most important quality dimensions from customers’ perception, which were obtained from four previous studies, applying factor analyses. The values obtained in the factor and regression analyses were correlated aiming to identify similar results found in the analyses. The results point that the attributes related to the personalized attendance, information about the assay results, as well as staff commitment, are considered the most important in the customers’ perception. From that, it was possible to identify fragilities in the service delivered and propose improvements concerning the customers’ perceived quality and, this way, maximize customer satisfaction. As a study limitation, the small sample size is pointed, which could have influenced the results found, by also influencing the methodology procedures in the regression analyses.

Published: May 2021

<div class="WordSection1"><p><strong>Objective</strong>. The aim of this study was to evaluate the number and mor- phological characteristics of the roots and root canals in mandibular anterior teeth, using cone beam computed tomography. <strong>Methods and materials. </strong>In this cross-sectional study, 1053 anterior mandibular teeth from 200 CBCT scans were evaluated. The teeth were complete- ly developed and should have had no fillings in the root or crown. The teeth were investigated in terms of the number of roots and root canals, the location of the apical foramen, the distance of the apical foramen to the anatomical apex, root length, crown length, dilacera- tions and the type of canals according to Vertucci’s classification. <strong>Re- sults</strong>. 87.9% of teeth had one root canal and of all of the teeth, three canines (0.3%) were found that had two roots. In 80.3% (n: 848) of cases the foramen apical location was central, then the buccal (9.3%), lingual (3.9%), distal (3.8%), and mesial (2.7%). The type of root ca- nals, according to Vertucci’s classification, with respect to prevalence, included type I (88.2%), type III (8.1%), type II (3.3%), type V (0.3%), and type VI (0.1%), respectively. In terms of the characteristics inves- tigated, bilateral symmetry was observed. Dilaceration was not seen in any of the teeth. <strong>Conclusion</strong>. The root canal morphology of mandibu- lar anterior teeth has great diversity that may differ between different races, and should be considered by all dentists in order to achieve the best dental treatment.</p></div><br clear="all" /><p> </p>
Wind Tunnel Testing of Offwind Sails
Authors: Ranzenbach Robert , Mairs Chris 
Published: May 2021

The primary purposes of this offwind sail investigation were to better understand offwind sail performance and to improve the ability to predict the performance of specific offwind sail shapes over a broad range of operating conditions. The study was designed to allow sail designers to answer the following questions: What are the optimal types of sails over specific bands of operating conditions and how is this optimum affected by changes in the vertical distribution of sail area (girth), camber (shape), and twist?
The specific goal was to demonstrate improvements in predicted sail performance over targeted narrow bands of operating conditions expected during various legs of the 1997-98 Whitbread Round The World Race™.
To achieve this goal, two major development tasks were first completed by the Glenn L. Martin Wind Tunnel (GLMWT), located at the University of Maryland College Park:
a. Model Test Rig Development;
b. Test Methodology Development.
Once these development tasks were completed, a broad range of offwind runners and reachers of varying design were evaluated over appropriate ranges of angle of attack and trim settings.

Towards a Robust Offshore Bonded Repair Strength Evaluation
Authors: Paboeuf Stephane , Mouton Luc , Sourisseau Quentin , Goupil Anne-Charlotte 
Published: May 2021

Since the early 2000s, the number of Floating Production, Storage and Offloading (FPSO) units is increasing significantly. And so now, half of the fleet is over than 10 years old. As FPSO are mainly installed in tropical areas, with marine environment, high temperature and high humidity, corrosion is a permanent threat. Maintenance of steel structures become a challenge for oil major companies in offshore operation. Indeed, when allowable corrosion limit are reached, plates are to be repaired. However the current “crop and renew” technique implies a number of major issues for owners such as: “hot work”, i.e., welding; temporary structure weakening; necessity to empty, clean and vent oil tanks, leading to a long down time and an expensive solution.
“Cold repair”, such as bonded repair, is an obvious solution, due to a short down-time and non-intrusively process. However, currently no standards or rules exist for this kind of repair and engineering faces problems as basic as strength qualification. To address the lack of knowledge on the strength assessment of bonded repair for primary structure, Bureau Veritas Marine & Offshore launched a Joint Industrial Project (JIP) named StrenghBond Offshore with oil companies, shipyards and suppliers. The main objectives of the JIP are to:
Assess short term and fatigue strength of typical bonded repairs,
Enrich knowledge of adhesive joints strength on typical offshore repairs cases,
Enable a better evaluation of the margin between the actual strength of a repair and the design load,
Validate the characterisation procedure for strength prediction of bonded assembly,
Define a robust strength prediction method,
Gather the collected experience in a industrially applicable guideline,
Standardise qualification process for offshore composite bonded repairs.
The project intends to provide a design approach for bonded reinforcement that is design orientated, accurate and recognized by the offshore industry.
Alfabetización digital en la educación. Revisión sistemática de la producción científica en Scopus

Published: May 2021

La incorporación de las tecnologías en los escenarios de interacción social ha propiciado cambios en la forma en la que las personas se comunican, aprenden y comparten información. En la educación, el acceso y la masificación de la infraestructura digital ha provocado la necesidad de conceptualizar y reconceptualizar desde diversas aristas el término alfabetización digital como una forma de comprender cuales son las habilidades que se necesitan para poder participar en un mundo hiperconectado. En este trabajo se realizó una revisión sistemática de la bibliografía relacionada con el tema utilizando la base de datos Scopus. Se elaboró un estudio diacrónico que examinó 138 artículos obtenidos a partir de los términos digital literacy, education y school. Se identificó una conceptualización temprana basada en la necesidad de incorporar habilidades para usar instrumentalmente las tecnologías, y una reconceptualización contemporánea en la que se supera la idea que dominar el hardware y software es suficiente para considerar a una persona digitalmente alfabetizada. Se concluye que, para hacer conceptualizaciones de alfabetización digital, necesariamente se deben considerar términos como alfabetización informacional, alfabetización computacional y alfabetización mediática, ya que sobre estos parámetros se articulan las nuevas alfabetizaciones basadas en la incorporación de las tecnologías en la educación.
The incorporation of technologies in scenarios of social interaction has led to changes in the way in which people communicate, learn and share information. In education, access and massification of digital infrastructure has led to the need to conceptualize and reconceptualize the term digital literacy from various angles as a way of understanding what are the skills needed to participate in a hyperconnected world. In this work, a systematic review of the bibliography related to the topic was carried out using the Scopus database. A diachronic study was carried out that examined 138 articles obtained from the terms digital literacy, education and school. An early conceptualization based on the need to incorporate skills to use technologies instrumentally was identified, and a contemporary reconceptualization in which the idea that mastering hardware and software is enough to consider a person digitally literate is overcome. It is concluded that, in order to make digital literacy conceptualizations, terms such as information literacy, computer literacy and media literacy must necessarily be considered, since new literacies based on the incorporation of technologies in education are articulated on these parameters.
