Authors: Mahamud M. A. , Samat N. , Tan M. L. , Chan N. W. , Tew Y. L.
Published: October 2019

Abstract. Land use land cover change (LULC) is a dynamic process, which is largely influenced by anthropogenic effect. In less urbanized area, human activities such as agricultural expansion, timber extraction and infrastructure development, has caused LULC transformation at alarming rate. Understanding of the potential future LULC changes is necessary for town planners and local authorities to formulate and design town planning. Besides that, the projected LULC patterns could also be incorporated into other models to further evaluate the impact of LULC changes on environment, agricultural, ecosystem, water resources and health. This study projected a future LULC scenario of Kelantan, Malaysia, using an integrated GIS CA-Markov model. The model achieved an accuracy of 78.57% when compared with the LULC map of 2008. Built-up area has increased by 111 km2, while forest area has decreased 1532 km2 in the past 15 years. Results showed that the built-up area, oil palm, and rubber plantation are expected to increase to 181.69 km2, 2142.48 km2, and 3076.24 km2, respectively, in 2025. By contrast, forest and paddy area are projected to decrease to 8548.20 km2, and 693.44 km2 respectively. Urban expansion is mainly found in the northern part of the state, while oil palm expansion in the southern part of the state. It was predicted that this pattern will continue in the next thirty years where built-up and agriculture area continued to expand at the stake of forest area. The findings provide useful information for planners in planning for future development and safeguarding the environment.

Abstract. Facility Management (FM) has becoming a crucial aspect in providing better service to the client/tenant or public as well as to minimize the maintenance cost. Group of buildings bounded by a defined boundary/spatial space such as a college, university, city or even a country have to manage their assets and space systematically with maximum potential/usage and minimum maintenance cost. Incorporating GIS plays innovative and effective role in asset and space FM especially. There are a lot of research and suggestions for it, but implementation is still average and quite new in Malaysia. University Kebangsaan Malaysia (UKM Bangi) has taken initiative to perform such idea with a full scale implementation. Currently, UKM utilizes GIS in nine modules, where one of the main module called SEPADU, an internal use module system for asset and space information system. This paper describes the implementation of integrated GIS solution in information system. Spatial data acquisition, database development and system for FM will be discussed in this paper.
Quantification of climate change impact on dam failure risk under hydrological scenarios: a case study from a Spanish dam
Authors: Fluixá-Sanmartín Javier , Morales-Torres Adrián , Escuder-Bueno Ignacio , Paredes-Arquiola Javier
Published: October 2019

Abstract. Dam safety is increasingly subjected to the influence of climate change. Its impacts must be assessed through the integration of the various effects acting on each aspect, considering their interdependencies, rather than just a simple accumulation of separate impacts. This serves as a dam safety management supporting tool to assess the vulnerability of the dam to climate change and to define adaptation strategies under an evolutive dam failure risk management framework. This article presents a comprehensive quantitative assessment of the impacts of climate change on the safety of a Spanish dam under hydrological scenarios, integrating the various projected effects acting on each component of the risk, from the input hydrology to the consequences of the outflow hydrograph. In particular, the results of 21 regional climate models encompassing three Representative Concentration Pathways (RCP2.6, RCP4.5 and RCP8.5) have been used to calculate the risk evolution of the dam until the end of the 21st century. Results show a progressive deterioration of the dam failure risk, for most of the cases contemplated, especially for the RCP2.6 and RCP4.5 scenarios. Moreover, the individual analysis of each risk component shows that the alteration of the expected inflows has the greater influence on the final risk. The approach followed in this paper can serve as a useful guidebook for dam owners and dam safety practitioners in the analysis of other study cases.
El poeta debe morir: fantasía, angustia y violencia en "Nos espera la noche" de Espido Freire
Authors: Rodríguez Samuel
Published: October 2019

Este artículo parte de un estudio estético-formal de la novela Nos espera la noche (2003) de Espido Freire (Bilbao, 1974), lo cual implica comprender las peculiaridades espacio-temporales de una mítica y angustiosa ciudad-personaje, Gyomaendrod, que trasciende la tradicional épica y los cuentos de hadas. Asimismo, resulta necesario comprender los resortes del poder y la desgarradora violencia que en él subyace, tanto física como simbólica, con especial incidencia en los personajes femeninos. Finalmente, compondremos un peculiar panegírico al poeta, al arte. Para ello haremos uso de herramientas metodológicas interdisciplinares que incluyen fuentes narratológicas, filosóficas, sociológicas y psicoanalíticas.

Timing of juvenile fish settlement at offshore oil platforms coincides with water mass advection into the Santa Barbara Channel, California
Authors: Nishimoto Mary M , Washburn Libe , Love Milton S , Schroeder Donna M , Emery Brian M , Kui Li
Published: October 2019

Recent pathways taken by pelagic juvenile fishes to offshore oil platforms were reconstructed from remotely sensed and in situ measurements of currents and hydrography. Juvenile fishes comprised 52.8% (16,952 of 23 species) of all individuals (32,080 juveniles and adults of 35 species)
observed during scuba surveys conducted about twice per week at two platforms in the eastern Santa Barbara Channel from May to August 2004. Blacksmith, Chromis punctipinnis (Cooper, 1863), and rockfishes (genus Sebastes, at least 18 taxa) comprised 95.1% of the recruits. Almost
all rockfishes recruited to the deepest part of the platforms surveyed (26 and 31 m), while most blacksmith recruited in shallower waters. The onset of the recruitment season for juvenile rockfishes (genus Sebastes, Scorpaenidae) coincided with the advection of a low salinity water
mass into the channel from the Southern California Bight. Before arrival of this water mass, water at the platforms resembled upwelled, high salinity water around the Point Conception region at the western channel entrance. Settlement pulses of rockfishes and blacksmith were observed during
advective events when salinity decreased in the upper 40 m and currents turned northwestward or intensified in that direction. Two abundant rockfish species [bocaccio, Sebastes paucispinis Ayres, 1854, and treefish, Sebastes serriceps (Jordan and Gilbert, 1880)] showed synchronous
patterns of juvenile settlement between platforms separated by 7 km. Our findings indicate that currents from the bight, rather than from central California, supplied recruits to settlement habitat in the eastern channel and that the spatial scale of connectivity for some fish populations
in this region is greater than the channel itself.

Polyglycerol- and sucrosebased green polyurethane adhesives for veneering
Authors: Mamiński Mariusz L. , Romanowska Anna
Published: October 2019

Veneering of particleboard with ABS foil and natural oak veneer was performed using polyglycerol- and sucrose-based polyurethane adhesives. Bonding strength between veneer and underlying board was determined according to EN 312 standard. Developed adhesive formulations exhibited bonding strengths between coating material and underlying board exceeding the surface soundness of particleboard (cohesive failure between 50 % and 100 %). Higher adhesion was found for natural oak veneers. Reactivity of the studied adhesives was comparable to those for commercial adhesives used in furniture industry. It has been demonstrated that biobased polyols can be considered environmentally benign and efficient components of polyurethane adhesives for furniture industry.

Authors: Mania Przemysław , Majka Jerzy , Zborowska Magdalena
Published: October 2019

The aim of this study was to examine some properties of heat-treated (200 °C) and densified (treated) bamboo. Density (ρ), equilibrium moisture content (EMC), sorption hysteresis (H), swelling (S), and Brinell hardness (HB) were examined and compared with untreated bamboo (Phyllostachys sp.) and common oak (Quercus robur L.). The density of heat-treated bamboo (ρ = 1170 kg/m3) was higher than that of untreated bamboo (ρ = 850 kg/m3) and oak wood (ρ = 670 kg/m3). The sorption isotherms were parameterized with the Guggenheim-Anderson-deBoer (GAB) model. Treated bamboo showed lower EMC than untreated bamboo and oak wood in the entire hygroscopic range. The swelling anisotropy index of treated bamboo was the lowest (1.09). The mean HB of treated bamboo (HB=132 MPa) was significantly higher than that of oak and untreated bamboo.

Overbrugging van procedurele breuklijnen bij een integrale aanpak van criminaliteit

De overheid zet in op een ‘integrale aanpak’ van ondermijning, terrorisme, cybercrime en financieel-economische criminaliteit. Die integrale aanpak heeft ook belangrijke procedurele gevolgen. Tegelijkertijd of achtereenvolgens worden bevoegdheden ingezet die worden genormeerd in verschillende rechtsgebieden. Het door deze bevoegdheden vergaarde materiaal wordt bovendien onderling gedeeld en gebruikt voor andere bevoegdheden. Door de betrokkenheid van meerdere rechtsgebieden en door die rechtsgebieden gescheiden te blijven benaderen, is sprake van procedurele breuklijnen die af doen aan daadwerkelijke integratie en aan de waarborgfunctie van het recht. Niet een duidelijkere keuze tussen handhavingsstelsels is de route naar overbrugging, maar het bereiken van overeenstemming over de grondbeginselen die aan de normering ten grondslag liggen.
Hygroscopic Behavior of Ammonium Sulfate, Ammonium Nitrate, and their Mixture Particles
Authors: Wu Li , Li Xue , Ro Chul-Un
Published: October 2019

Inorganic species such as ammonium sulfate (AS) and ammonium nitrate (AN), which significantly affect air quality, visibility degradation, and climate change, occupy 20–50% among ambient fine aerosol mass. In the present study, laboratory generated, micrometer sized, pure AS, AN, and AS-AN mixture aerosol particles at 9 mixing ratios (mole fraction of AS, X
AS =0.02, 0.035, 0.1, 0.15, 0.2, 0.28, 0.5, 0.6, and 0.8) were examined systematically to observe their hygroscopic behavior, to derive experimental phase diagrams for efflorescence and deliquescence, and to obtain chemical micro-structures using in-situ Raman microspectrometry (RMS). All the nebulized AS-AN mixture particles experienced only one-stage efflorescence at 15–40% relative humidity (RH) during dehydration process, revealing that all the compounds in the particles crystallized nearly simultaneously. Nebulized AS-AN mixture particles of eutonic composition (X
AS =0.035) showed singlestage transition at a mutual deliquescence relative humidity (MDRH) of 63.6%, whereas the others exhibited two-stage deliquescence transitions during humidification process, i.e., the eutonic component dissolved at MDRH, and the remainder in the solid phase dissolved completely at their DRHs, resulting in a phase diagram composed of four different phases, as predicted thermodynamically. The measured MDRH and second DRHs of mixture particles with mixing ratios of 0.035<X
AS<0.33 are either higher or lower than the theoretical values, while only the experimental second DRHs of mixture particles with mixing ratios of X
AS>0.33 are higher than the theoretical values calculated from E-AIM model, which might be due to the variations of crystal formation when the efflorescence occurred. As reported previously, AS and AN mixture droplets can crystallize as the mixture of pure crystal and stable and/or metastable double salts (2AN·AS and/or 3AN·AS, respectively) and the degree of metastability might differ under different conditions. Our results also indicate that the AS-AN mixture particles can crystallize into different forms, leading to diverse MDRHs and DRHs than the theoretical ones, which can promote their capability of probable heterogeneous chemistry on the aqueous aerosol surface.
Assessment of affiliative behaviour in mares

Published: October 2019

The first aim of study was to assess the feelings of friendship and companionship among mares released into a paddock in different combinations by analysing the duration of behaviours occurring there as well as changes in heart rhythm. The second aim of the study was to develop a procedure for creating different herd configurations based on the individual affiliative needs of horses, expressed as a score. The study was conducted on 12 one-year-old Thoroughbred mares. It was carried out on three consecutive days during the horses’ 30-minute stay in the paddock. On the first day, all mares were in the paddock together. On the second day, they were released in pairs, and on the third day, they were released individually. Expressions of affiliative behaviours (feelings of friendship and companionship) towards another horse were timed. The activity of the parasympathetic system was measured as well. The results were used to score the mares’ affiliative behaviour using a procedure of our own design. Feelings of friendship and companionship were found to be most strongly expressed when a herd of horses with an established hierarchy including each individual was present on the paddock. Releasing horses in pairs is a good substitute for releasing the entire herd, but cannot replace true herd relations, due to decreased expression of feelings of closeness and companionship, such as play or grooming. Releasing horses into the paddock individually is not recommended because it disturbs social behaviour, thus increasing emotional excitability. Emotional excitability is calmed when horses are released in pairs, so this configuration can be used for excitable horses. The best solution, however, seems to be the use of the affiliative behaviour score proposed in the study, as an indicator of the individual needs of mares when creating various herd configurations.
“Folia Turistica” in 1990-2018 – a Bibliometric Analysis
Authors: Szczechowicz Bartosz
Published: October 2019

Purpose. The aim of this article is to investigate the characteristics of “Folia Turistica” (FT), covering such questions as thematic profile, authors, and affiliations, internationalization, taking into account the content of issues from the origins of the magazine (1990) to the present (2018).

Method. The aim of the work was achieved through two research methods, which were used in a complementary fashion: bibliometric analysis (in which data that quantitatively expressed the content of the relevant issues of FT was gathered, processed, and interpreted) and participatory observation, from the author’s participation in FT’s editorial staff.

Results. FT is predominantly concerned with issues in the social sciences, it is closely tied to the humanities, and the natural sciences are also present, though this profile has changed over time. Contributors to FT have included more than 400 Polish authors over thirty years, representing almost ninety schools, from academies of physical education and universities to economic, agriculture, natural science, and technical colleges, and others. Though the number of foreign authors is limited, we should stress that they represent academies on four continents, and in many cases are figures with very high positions in the international community.

Research and conclusions limitations. The limitations derive from the properties of the methods used, primarily displayed in the identification of FT’s thematic profile. This arbitrarily identified profile subordinates every article to a single overriding field of study – while many articles published in FT are multi- or interdisciplinary.

Practical implications. This diagnosis of FT includes postulates for how the magazine might develop in the future.

Originality. The specialist literature (especially Polish) fairly seldom makes critical evaluations of scholarly publications.

Type of article. Empirical.
Hardness prediction of a cold rolled
Nimonic 80A exhaust valve spindle
Authors: Kang S.W. , Heo S.J. , Yoo J.H. , Kang J.H.
Published: October 2019

Purpose: of this paper is to predict the hardness of cold rolled exhausts valve spindle
fabricated of Nimonic 80A via axisymmetric finite element analysis, compression testing,
and hardness inspection.
Design/methodology/approach: The stress-strain relationship of Nimonic 80A was
obtained via compression testing with deformation ratios of 10%, 20%, and 30%. Hardness
changes caused by the strain hardening effect were measured in cut specimens in both the
axial and circumferential directions following compression testing. The effective strain at the
measurement position was calculated via finite element analysis. The regression equation
for hardness changes caused by work hardening was derived from analysed strain and
inspected hardness. The cold-rolling deformation of an exhaust valve spindle was analysed
using axisymmetric finite element analysis.
Findings: The stress-strain relationship calculated from compression testing was well
expressed using the Holloman equation and the strain-hardness relationship by strain
hardening was successfully regressed using the shifted power law model for Nimonic 80A,
Nickel-Chromium based super alloy.
Research limitations/implications: This research focused hardness prediction of
spindle after ring rolling operation for generating beneficial compressive surface residual
stresses for enhancing fatigue life. Further research to quantify compressive residual stress
after rolling shall be followed to increase fatigue life.
Practical implications: The cold rolling process is a typical incremental forming method
and should be analysed under three-dimensional conditions. However, it takes lots of
time to solve incremental forming analysis. To predict hardness distribution after rolling in
the manufacturing field, FE analysis was performed under two-dimensional axisymmetric
conditions based on the assumption of no friction generated by the rolling tool. The deformed
shapes and hardness distribution from the inspection quality standard and two-dimensional
FE analysis showed very similar results. Simplified finite element analysis method for ring
rolling process for local area could be very effective method in the industrial field.
Originality/value: The stress-strain relationship and the hardness and strain relationship
were derived by compression test and hardness measurement for compressed specimen
for Nimonic 80A, Nickel-Chromium based super alloy. And simplified finite element analysis
method was suggested to predict deformed shape and hardness distribution of locally cold rolled region and achieved similar result between FE analysis result and Quality standard.
Suggested method would be very effective method to engine spindle manufacture to predict
hardness of different size of product.

Published: October 2019

Purpose: Due to changes in the volume of oil transportation, part of the pipelines must be
temporarily decommissioned. The purpose of the work is theoretical and experimental study
of pressure fluctuations during operation of oil pipelines and their impact on the durability
of the pipeline material in work state and after temporary decommissioning (conservation).
Design/methodology/approach: The results of oil pressure fluctuation research have
given a chance to choose the terms of experimental research providing of the pipe metal
mechanical features changes research during oil pipeline exploitation.
Findings: Fatigue test modes are selected based on the calculations of the mathematical
model developed. Experimental studies of the dependence of the fatigue strength of the
pipe material on the conditions of operation have been carried out, which made it possible to
determine the parameters of the fatigue curve of the samples. Has been defined that fatigue
strength for the new metal pipe samples is more for 20-25% than for the metal samples
which had the contacts with lime milk and for 30-40% more than for metal samples which
were under exploitation.
Research limitations/implications: In the future, more combination of "pipe material –
preservation medium" should be explored to establish pain of general regularities.
Practical implications: The probabilistic curves of the pipeline non-destruction are
constructed, which will be used for practical calculations of the reliability and durability of
the 13G1S-U steel pipelines.
Originality/value: Mathematical model is made that describes non-stationary oil moves in
oil pipeline, that has been caused by jump like changes of oil supply in oil pipeline, on this
basis was defined, that oil pressure in oil pipeline provides within non stationary process in
a range of 0.4-0.6 Hz frequency and amplitude fluctuation of pressure is 0.1-0.5 MPa.
The Minimum Wave Resistance of Hull Form Design Method Based on CFD Method
Authors: Zhang Bao-Ji , Zhang Chi , She Wen-Xuan
Published: October 2019

To reduce the resistance of the ship in actual navigation, a hull form optimization design method for minimum wave resistance is proposed. A numerical wave tank of regular waves is established based on the CFD (Computational Fluid Dynamics) theory. Overlapping grid technology is adopted to mesh the hull form and free surface. The new hull offsets are generated by using the parameters of modified function as design variables. The geometric expression and reconstruction of optimized hull form is determined through the three-dimensional CAD (Computer Aided Design) modeling technology. The displacement limit was used as the basic constraint, and other additional constraints were considered; nonlinear programming quadratic line search algorithm was used to set up a mathematical model of hull form optimization on the ISIGHT platform. The optimization calculations of Wigley hull form and surface ship DTMB5415 are carried out. Compared with the parent hull, the wave resistance of the optimized hull form is significantly reduced, and the feasibility of this method is confirmed. The research results can provide technical support for the development of "green ship"design.

Published: October 2019

Esta investigación estableció relaciones de interdependencia y predicción entre experiencia desagradable y creencias irracionales, ansiedad evaluativa, autorregulación en el estudio y estrés académico, variables de la competencia para rendir en contextos de alta exigencia. Participaron 221 aspirantes de academias preparatorias a la función pública del cuerpo de Maestros. Las variables fueron medidas mediante autoinformes validados. El diseño fue ex post-facto lineal, con análisis inferenciales y estructurales. Los resultados mostraron relaciones significativas positivas de interdependencia de la experiencia desagradable con las creencias irracionales y respuestas fisiológicas de estrés, así como negativas con la autorregulación en el estudio. Además encontraron una relación estructural predictiva significativa entre experiencia desagradable y respuestas cognitivas, conductuales y fisiológicas de estrés. Estos resultados validan parcialmente las relaciones del modelo CAERE, explicando el aprendizaje en contextos estresantes, y evidencian la necesidad de entrenar a los estudiantes ante estas situaciones.

This investigation established unpleasant past experience in interdependent and predictive relations with irrational beliefs, test anxiety, self-regulated study and academic stress, variables belonging to the competency for performing in highly demanding contexts. Participants were 221 candidates from preparatory academies who were competing for posts as public elementary school teachers. The variables were measured using validated self-reports. A linear, ex post-facto design was used, with inferential and structural analyses. Unpleasant experience was shown to have significant, positive, interdependent relations with irrational beliefs and physiological stress responses, as well as negative relations with self-regulated study. Significant, predictive, structural relations were found between unpleasant experience and cognitive, behavioral, and physiological stress responses. These results partially validate the relationships of the SLPS Competency model, explaining learning in stressful contexts, and offer evidence of the need to train students in these situations.

La calidad de los estudios incluidos se evaluó a través de la escala Newcastle-Ottawa. Resultados: De los 164 estudios encontrados en la búsqueda, once estudios cumplieron los criterios y fueron considerados diez de alta calidad metodológica y uno de moderada. La revisión sistemática mostró que niveles prenatales de vitamina D <50 nmol/L se asocian frecuentemente a un peor desarrollo mental, motor y del lenguaje de sus hijos en comparación con las madres con concentraciones ≥50 nmol/L. Conclusión: Aunque existe poca evidencia científica que corrobore la relación entre la deficiencia de vitamina D prenatal y su impacto en el neurodesarrollo de los hijos, los datos actuales sugieren un perjuicio sobre el desarrollo mental, motor y del lenguaje del niño.

Background: A deficiency of vitamin D during pregnancy has a negative impact on the health of the mother and the child. Objective: To evaluate the effect of vitamin D status during pregnancy on the neurodevelopment of children. Selection of studies: We explored studies that linked the maternal status of vitamin D with neurodevelopment in the infant. The selected studies were identified through a systematic review of the scientific literature published in PubMed/MEDLINE, Scopus and Cochrane until January 2018. The quality of the included studies was carried out through the Newcastle-Ottawa scale. Results: 164 studies were identified and reviewed for selection. At the end of this review, 11 studies were included, all of high methodological quality. This systematic review shows that prenatal vitamin D levels <50 nmol/L are associated with worse mental, motor and language development of their children compared with pregnant women with good vitamin D status. Conclusion: There is still little scientific evidence to corroborate the relationship between prenatal vitamin D deficiency and its impact on the neurodevelopment of children, although current data suggest a detrimental effect on the child's mental, motor and language development.
Intervention programs in educational psychology: bridging research and practice
Authors: Gomes-Koban Clara , Calet Nuria , Defior Sylvia

El término intervención basada en evidencia se está utilizando cada vez más en la investigación educativa. La necesidad de llevar a cabo programas de intervención basados en evidencia científica se fundamenta en que la probabilidad de lograr resultados positivos al implementar dichos programas es mayor. Sin embargo, la brecha entre la investigación y la práctica se mantiene en los países de habla hispana. Utilizando ejemplos del área de investigación en lectura, este trabajo tiene como objetivo promover la reflexión y la discusión sobre la relación entre la evidencia científica y la práctica educativa, particularmente en el contexto de los países hispanohablantes. Por un lado, existe la importancia de generar evidencia a través del diseño de estudios de alta calidad basados ​​tanto en sólidos antecedentes teóricos como en altos estándares metodológicos. Por otro lado, existe el valor de la experiencia profesional de los profesores en realidades escolares muy diversas. ¿Cómo podemos construir puentes para conectar estas dos partes indispensables y atender mejor a las poblaciones de interés? Defendemos la necesidad de desarrollar un sistema de colaboración sostenible entre la comunidad científica y la educativa que permita el intercambio continuo y un apoyo recíproco mediante relaciones más estables.

The term evidence-based intervention has been increasingly used in educational research. Calls for the use of intervention programs based on supportive empirical evidence rely in the recognition that the likelihood of achieving positive results when implementing such programs increases. Nevertheless, the gap between research and practice remains also in Spanish-speaking countries. Using examples from the area of reading research, this work aims at promoting the reflection and discussion about the relationship between scientific evidence and school practice, particularly in the context of Spanish-speaking countries. On the one side, there is the importance of generating evidence through the design of high-quality studies based on both sound theoretical background and high methodological standards. On the other side, there is the value of professional experience gathered by the teachers in very diverse school realities. How can we build a bridge to connect these two indispensable parts in order to be able to better serve the populations of interest? We defend the need of developing a sustainable collaborative system between the research community and the educational centers that enables continuous exchange and reciprocal support in longer lasting relationships.
Should We Use the Digital Models in Pediatric Dentistry?

Published: October 2019

Objectives: This study aims to
compare the measurements of the extraction spaces in the plaster models and
digital dental models and to investigate the usability of the digital models in
preventive and interceptive appliances in pediatric dentistry clinics.Material and Methods:
In the dental models of 56 patients whose first molar teeth were extracted in
the early period, the dental arch length of the extraction spaces were measured
with a digital caliper in the plaster model (Control Group), with computer
software in the digital model (Experimental Group). Measured values were
compared using a t-test and statistical significance levels were determined.Results: In plaster models and digital
models, the measured mean arc length of the extraction spaces were 6.94 mm and
6.83 mm, respectively. There was no statistically significant difference
between the two measurement methods (p>0.05).

Conclusions: The use of digital
models is recommended in pediatric dentistry clinics due to shorter chair time
in pediatric patients, effective treatment planning/follow-ups, reducing treatment
costs and other advantages.
A Cross-cultural Comparison of Medical Science Subject Classification in the KDC and the DDC

Published: October 2019

This study reports the preliminary results of a cross-cultural comparison of Medical Science in the Korean Decimal Classification (KDC) and in the Dewy Decimal Classification (DDC). Despite having similar purposes, to serve the public and emphasize the significance of standardization in medical science, a comparison of the two classification systems shows the influences of social and cultural inferences of classification systems in medicine.

AKTERI MOBINGA U VOJNOJ SREDINI
Authors: Čolaković Radomir , Čolaković Lončar Jelena
Published: October 2019

U radu opisujemo, prvi put na ovim prostorima, psihološke profile aktera mobinga u vojnoj sredini. Akteri mobinga u vojnoj sredini su nešto specifičniji profili ličnosti nego u civilnom sektoru. Do sada se uglavnom govorilo o moberu i žrtvi mobinga. Mober je psihopatske strukture ličnosti i najčešće je na komandnom formacijskom mjestu, ali to nije pravilo. Žrtva mobinga je najčešće na nižem formacijskom mjestu u vojnoj hijerahiji i uglavnom su to potčinjeni članovi kolektiva.Žrtve su u najvećem broju slučajeva, među najsposobnijim, najstručniji u okviru formacijskog mjesta i svog VES-a1. Motivisani su za vojni poziv i imaju visok motiv za postignućem. Vole svoj posao i reaguju na stimulativne mjere. To su starješine koje izazivaju zavist kolega, pošteni, koji se strogo drže vojnih propisa. U svom radnom vijeku su, zbog svojih rezultata, više puta nagrađivani i pohvaljivani. Na povjerenim poslovima i radnim zadacima, ispoljavaju pedantnost u radu, poštuju rokove izvršenja zadataka, striktno se drže vojnih propisa, inovacija u radu i samoinicijativnosti. Posebno je interesantan još jedan profil, koji spada u aktere mobinga, a koji do sada nije spominjan u teoriji i praksi: to su imitatori mobera. Oni predstavljaju „sigurnosni kordon“ mobera, grupu za podršku. Uglavnom su to, psihološki gledano, jednostavne strukture ličnosti. Kada uđu u „posao imitatora“, tada često svoja zapažanja prevode na jezik sopstvenog interesa. Njima se dozvoljavaju povremena odstupanja u vojničkom ponašanju. Među imitatorima mobera ima starješina, koji su u prošlosti imali vojničkih „grijehova“, tako da ih mober zaista „drži u šaci“. Rad je koristan za vojne psihologe, a naročito starješine na komandnim pozicijama, koji na osnovu iznijetih činjenica, mogu lako da prepoznaju aktere mobinga u vojnom kolektivu i da na osnovu tih saznanja preduzmu adekvatne mjere prevencije.
Physical habitat modeling methodology and applications
Authors: Nalamothu Ravi
Published: October 2019

The water management districts in Florida are required by s. 373.042, F.S. to establish minimum flow and levels (MFLs) for a priority list of water bodies that is updated each year. These MFLs are established for water bodies to prevent “significant harm” to the water resources or ecology because of withdrawals for beneficial use, and can be an effective water resource management tool. Protection of the resource from significant harm is a benefit to the variety of existing users of the resource as well as the ecological systems supported by the water bodies. This article presents an overview of a modeling technique and an associated tool developed to protect the instream habitat from significant harm.
Regulated spindle orientation buffers tissue growth in the epidermis

Tissue homeostasis requires a balance between progenitor cell proliferation and loss. Mechanisms that maintain this robust balance are needed to avoid tissue loss or overgrowth. Here we demonstrate that regulation of spindle orientation/asymmetric cell divisions is one mechanism that is used to buffer changes in proliferation and tissue turnover in mammalian skin. Genetic and pharmacologic experiments demonstrate that asymmetric cell divisions were increased in hyperproliferative conditions and decreased under hypoproliferative conditions. Further, active K-Ras also increased the frequency of asymmetric cell divisions. Disruption of spindle orientation in combination with constitutively active K-Ras resulted in massive tissue overgrowth. Together, these data highlight the essential roles of spindle orientation in buffering tissue homeostasis in response to perturbations.
Matrix metalloproteinase 1 modulates invasive behavior of tracheal branches during entry into Drosophila flight muscles

Published: October 2019

Tubular networks like the vasculature extend branches throughout animal bodies, but how developing vessels interact with and invade tissues is not well understood. We investigated the underlying mechanisms using the developing tracheal tube network of Drosophila indirect flight muscles (IFMs) as a model. Live imaging revealed that tracheal sprouts invade IFMs directionally with growth-cone-like structures at branch tips. Ramification inside IFMs proceeds until tracheal branches fill the myotube. However, individual tracheal cells occupy largely separate territories, possibly mediated by cell-cell repulsion. Matrix metalloproteinase 1 (MMP1) is required in tracheal cells for normal invasion speed and for the dynamic organization of growth-cone-like branch tips. MMP1 remodels the CollagenIV-containing matrix around branch tips, which show differential matrix composition with low CollagenIV levels, while Laminin is present along tracheal branches. Thus, tracheal-derived MMP1 sustains branch invasion by modulating the dynamic behavior of sprouting branches as well as properties of the surrounding matrix.
