Degradation of Computer-aided Design/Computer-aided Manufacturing Composites by Dietary Solvents: An Optical Three-dimensional Surface Analysis
Authors: Munusamy SM , Yap AU , Ching HL , Yahya NA 
Published: February 2020

Clinical Relevance
Computer-aided design/computer-aided manufacturing (CAD/CAM) composite resins are susceptible to degradation by dietary solvents. Dietary counselling is prudent when placing such CAD/CAM restorations.

SUMMARY
This study determined the effect of dietary solvents on the surface roughness (Ra) of direct, indirect, and computer-aided design/computer-aided manufacturing (CAD/CAM) dental composites. The materials evaluated were a direct composite (Filtek Z350 XT [FZ]), an indirect composite (Shofu Ceramage [CM]), and four CAD/CAM composites (Lava Ultimate [LU], Shofu Block HC [HC], Cerasmart [CS], and Vita Enamic [VE]). Specimens (12×14×1.5 mm) of each material were prepared, measured for baseline Ra, ranked, divided into six groups (n=12), and conditioned in the following media for 1 week at 37°C: air (control), distilled water, 0.02 N citric acid, 0.02 N lactic acid, heptane, and 50% ethanol-water solution. The composite specimens were then subjected to postconditioning Ra testing using an optical three-dimensional surface analyzer (G4e, Alicona Imaging GmbH, Raaba, Austria). Inter-medium and inter-material comparisons were performed with one-way analysis of variance and post hoc Bonferroni test at a significance level of α=0.05. Mean Ra values ranged from 0.086 ± 0.004 μm to 0.153 ± 0.005 μm for the various material/medium combinations. For all materials, conditioning in air (control) and distilled water generally resulted in significantly lower mean Ra than exposure to other dietary solvents. Conditioning in citric acid presented the roughest surfaces for FZ, CM, and CS. For LU, HC, and VE, exposure to lactic acid, heptane, and ethanol solution resulted in the highest mean Ra. Regardless of conditioning media, FZ had the highest and VE the lowest mean Ra compared with other composites. The CAD/CAM composites remained susceptible to surface degradation by dietary solvents despite their industrial polymerization.

Abstract

OBJECTIVE
To compare a ventral and a left lateral endoscopic approach to coelioscopy in bearded dragons (Pogona vitticeps).

ANIMALS
18 adult bearded dragons.

PROCEDURES
In a randomized crossover design involving 2 surgical approaches, anesthetized bearded dragons first underwent coelioscopy with a ventral approach (left lateral of midline next to the umbilicus; animal positioned in dorsal recumbency) or left lateral approach (intercostal; animal positioned in right lateral recumbency) and then with the alternate approach. A 2.7-mm × 18-cm, 30° oblique telescope with a 4.8-mm operating sheath and CO2 insufflation at 2 to 5 mm Hg were used. Ease of entry into the coelom and ease of visual examination of visceral structures were scored.

RESULTS
Both approaches were straightforward, with the left lateral approach requiring significantly more time than the ventral approach. Scores for ease of visual examination for the heart, lungs, liver, stomach, intestines, pancreas, gallbladder, left kidney, gonads, and fat body were good to excellent. Visual examination of the spleen and adrenal glands was difficult in most animals via either approach. The left kidney, testis, and vas deferens were easier to see with the left lateral approach, whereas the pancreas in females and gallbladder in both sexes were easier to see with the ventral approach. All bearded dragons recovered without complications from the procedures, except for one with nephritis, renal gout, and hepatic necrosis.

CONCLUSIONS AND CLINICAL RELEVANCE
Both coelioscopy approaches could be safely and effectively used in bearded dragons. Choice of approach should be based on the coelomic structures requiring evaluation.
Impact of Cedzyna Reservoir on Selected Physicochemical Parameters of River Water Quality (Swietokrzyskie Mountains, Poland)
Authors: Przybylska Joanna , Kaleta Joanna , Kozłowski Rafał 
Published: February 2020

Abstract
The monitoring of selected physicochemical parameters and chemical composition of water was conducted in 2017-2018 in the Lubrzanka river and the Cedzyna reservoir (Swietokrzyskie Mountains, Poland). The results indicate that the impact of reservoir on the quality of river water depends on natural characteristics of the catchment as well as on the present anthropogenic pressure. Retention of water in the reservoir caused seasonally diversified changes in analysed parameters, including an increase in water temperature, retention of major ions, nutrients and trace elements. Further research is needed to assess the risk of contamination of lower course of the river with metals deposited in reservoir’s bottom sediments.
Towards Change Management in Tourism: the Evidence from North Macedonia
Authors: Hristova Snezana , Misoska Ana Tomovska , Kovachevski Dimitar 
Published: February 2020

Abstract
This paper investigates the perceptions and practices of managers of the tourism sector with regards to change management. It has been suggested that change management is an inevitable element for tourism businesses to increase their speed of response to market and competitive changes. Logically, it can be argued that tourism managers are best placed to initiate and facilitate this change. The primary data were obtained through a survey, carried out in tourist agencies in the Republic of North Macedonia and evaluated by using the tools of descriptive statistics and the methods of comparison, induction, deduction and synthesis. The key findings indicate that the majority of the respondents were familiar with the term change management and they implemented the change management practices. However, work still needs to be done to help the remaining companies to understand the necessity of changing the paradigm. Regarding the practical implications, this paper can serve as a stepping stone for future research that can uncover the potential, experiences and outcomes of change management in the tourism sector in the country.
Measurement Science is the Science of Sciences - There is no Science without Measurement
Authors: Witkovský Viktor , Frollo Ivan 
Published: February 2020

Abstract

Omnia in mensura et numero et pondere disposuisti is a famous Latin phrase from Solomon’s Book of Wisdom, dated to the mid first century BC, meaning that all things were ordered in measure, number, and weight. Naturally, the wisdom is appearing in its relation to man. The Wisdom of Solomon is understood as the perfection of knowledge of the righteous as a gift from God showing itself in action. Consequently, a natural and obvious conjecture is that measurement science is the science of sciences. In fact, it is a basis of all experimental and theoretical research activities. Each measuring process assumes an object of measurement. Some science disciplines, such as quantum physics, are still incomprehensible despite complex mathematical interpretations. No phenomenon is a real phenomenon unless it is observable in space and time, that is, unless it is a subject to measurement. The science of measurement is an indispensable ingredient in all scientific fields. Mathematical foundations and interpretation of the measurement science were accepted and further developed in most of the scientific fields, including physics, cosmology, geology, environment, quantum mechanics, statistics, and metrology. In this year, 2020, Measurement Science Review celebrates its 20th anniversary and we are using this special opportunity to highlight the importance of measurement science and to express our faith that the journal will continue to be an excellent place for exchanging bright ideas in the field of measurement science. As an illustration and motivation for usage and further development of mathematical methods in measurement science, we briefly present the simple least squares method, frequently used for measurement evaluation, and its possible modification. The modified least squares estimation method was applied and experimentally tested for magnetic field homogeneity adjustment.
Investigation of Phase Pattern Modulation for Digital Fringe Projection Profilometry
Authors: Liu Cheng-Yang , Wang Chung-Yi 
Published: February 2020

Abstract
The fringe projection profilometry with sinusoidal patterns based on phase-shifting algorithms is commonly distorted by the nonlinear intensity response of commercial projector. In order to solve this issue, sinusoidal width modulation is presented to generate binary sinusoidal patterns for defocusing the projection. However, the residual errors in the phase maps are usually notable for highly accurate three-dimensional shape measurements. In this paper, we propose the fringe patterns of the sinusoidal, square, and triangular periodic waveforms with seven-step phase-shifting algorithm to further improve the accuracy of three-dimensional profile reconstruction. The absolute phase values are calculated by using quality guided path unwrapping. We learn that by properly selecting fringe patterns according to the target shape, the undesired harmonics of the measured surface have negligible effect on the phase values. The experiments are presented to verify the imaging performances of three fringe patterns for different testing targets. The triangular fringe patterns are suitable for the shape measurements of complex targets with curved surfaces. The results provide a great possibility for high-accuracy shape measurement technique with wider measuring depth range.
Practical and Pastoral Perspectives on Inter-confessional Marriage in the Finnish Orthodox Context
Authors: Metso Pekka 
Published: February 2020

Abstract
In this article, the phenomenon of inter-confessional marriages and families is studied in the context of Finnish Orthodoxy. The focus is on the wedding services, religious upbringings and participation in Church life from the perspective of inter-confessional marriages/families: How does the ecumenical reality influence them? Sociologically, the family has a central role in relation to beliefs, religious practices and activities. The religious upbringing of most Orthodox children takes place in a family of two Christian traditions. In the lived reality of the Finnish Orthodox population, the co-existence of two traditions (Orthodox and non-Orthodox) in inter-confessional marriages is not always non-problematic. In dialogue with the Lutheran Church, the Orthodox Church of Finland has aimed to promote harmony and mutual respect for the two traditions in inter-confessional families, as well as to fortify the Orthodox identity of its members.
Gemeinschaft von Verschiedenheiten – religionsphilosophische Vorüberlegungen
Authors: Oancea Dorin Zosim 
Published: February 2020

Abstract
Communion of diversities. Interconfessional marriages are understood as communions of diversities. It is the author´s opinion that the first three chapters of the Book of Genesis offer a model of man´s constitutive and simultaneous communion with God and the world. Each person experiences bondings with different theocosmic surroundings or spaces, able to give her/him a special identity. Postparadisiac life is marked by an also simultaneous illegitimate diminishing and enhancing of communion in all directions, included in everybody`s bonding system. The communion of diversities, mixed marriages included, participate in this process, which can be overcome only through life in Christ.

Published: February 2020

AbstractIn the context of global digital evolution, the implementation of dynamic (online) platforms seems to be essential in order to facilitate the access to rare and/or valuable documents. Insufficiently exploited as seen in the small number of requests, the digitization of these resources is a concept of important value to research activities dealing with the history of translation and not only. Consequently, digitization is likely to bring together a larger number of readers but also to reveal multiple directions of future research.
The Human Capital Dimension within the Organizational Equation. Gliding Between Virtual and Traditional Teams
Authors: Stratone Mădălina Elena , Vătămănescu Elena-Mădălina 
Published: February 2020

Abstract
There is a body of literature on virtual teams that is growing faster and faster; however, the knowledge about the benefits and the challenges faced by the virtual teams are still not very well outlined or thoroughly discussed. The purpose of this paper is to fill a part of the gap by reviewing specialized literature about the effectiveness of the virtual teams versus the traditional teams. Moreover, the study underlines the challenges faced by the virtual teams from different standpoints (i.e., identity, culture and diversity, leadership, communication and motivation, decision-making and conflicts, technology, creativity) and highlights the best ways/tools to cope with them. By performing this theoretical overview, the study aims to advance an articulate perspective on the organizational landscape and processes in line with today’s challenges in terms of human capital, in particular and of intellectual capital, in general. As the depicted research directions indicated, people are not ready yet to totally move to the virtual world and to give up face-to-face communication, feeling more comfortable to work within a traditional team. This situation is illustrative of the fact that there is still much to explore about the virtual teams and about how they can reach their best potential in order to be effective.
