A 40-Year Analysis of the Hydrological Drought Index for the Tigris Basin, Turkey
Authors: Ozkaya Arzu , Zerberg Yeliz
Published: March 2019

Drought is a natural disaster that occurs globally when water availability is significantly below normal levels. Drought assessment is important for water resource planning, and therefore indexes can be used to characterize drought magnitudes. Using the monthly streamflow data at 47 stations from 1972 to 2011, the streamflow drought index (SDI) series with 3- (SDI-3), 6- (SDI-6), and 12-month (SDI-12) time scales were calculated, and the hydrological drought of the upper Tigris Basin in Turkey has been assessed. The results showed that almost all stations experienced at least one severe drought during the study period. The results revealed that since the early 1990s the study area has become drier. Using the data for a 12-month period and the area of the sub-basins for each flow monitoring station, area-weighted SDI-12 (WSDI) values were constructed. According to the WSDI results, the intensity and number of drought conditions increased during every 10-year period. This outcome has been verified using the maps of averaged SDI-12 values over the Tigris Basin. We noticed from observations of the maps that the time domain zones in lower latitudes experienced drought earlier as compared with zones in higher latitudes.
EFFECT OF KISPEPTIN RECEPTOR BLOCKADE ON BEHAVIORAL INDICATORS OF RATS IN STANDARD TESTS
Authors: Tkacheva M.A. , Inyushkina E.M. , Sharafutdinova A.Yu. , Inyushkin A.N.
Published: March 2019

Kisspeptin, the regulatory peptide, is known as a fertility stimulator and reproductive regulator. Its activity is mediated by specific interaction with GPR54 receptors (or Kiss1R). There are indications of correlation between the kisspeptin system in the brain and the function of circadian oscillator, the suprachiasmatic hypothalamus nucleus, which stimulates the cells of the kisspeptin neural network of the anteroventral periventricular nucleus in the hypothalamus, which in turn leads to the release of the hypothalamic gonadoliberin in the time period immediately preceding the start of the total daily locomotor activity. There is also evidence on the presence of fibers containing kisspeptin and on kisspeptin receptor expression in the suprachiasmatic nucleus, which indicates the function of kisspeptin as a feedback signal from the reproductive to the circadian system. Along with kisspeptin reproductive function, there is evidence on its importance in the behavior regulation.
The aim of the work is to study the effect of intranasal administration of a specific GPR54 antagonist of p-234 receptors on the behavior of male rats in standard tests, such as “Open Field” and “Dark-Light box”.
Materials and Methods. The experiments were conducted on 12 Wistar male rats weighing between 240 and 270 g. For control and experimental groups, the 12:12 h. light/dark illumination mode was set. The studies were conducted in the first half of the circadian day. In the experimental group the antagonist of p-234 kisspeptin receptors was administered intranasally; in the control group water for injection was administered using the same method.
Results. Administration of kisspeptin receptor antagonist to experimental animals at the beginning of the subjective day led to a decreased anxiety level and stimulated the exploratory behavior in rats.
Conclusion. The revealed behavioral changes can contribute to the implementation of the already known kisspeptin function as a reproductive stimulator, or act as an independent component in the physiological activity of a kisspeptin system.

Keywords: antagonist of kisseptin receptors p-234, behavioral tests.
CHANGES IN ELECTROENCEPHALOGRAM PATTERN IN RIGHT- AND LEFT-HANDERS DURING IMAGINARY MOVEMENTS
Authors: Morenova K.A. , Vedyasova O.A.
Published: March 2019

The objective of the paper is to analyze changes in electroencephalogram (EEG) pattern in right- and left-handers during imaginary movements of leading and non-leading legs.
Materials and Methods. The authors examined 40 right-handers and 20 left-handers, whose motor domination profile was determined by standard tests. EEGs were recorded at rest and during imaginary rotational movements of the right and left legs. NVX 36 digital DC EEG neurovisor, “10–20” system, was used for this perpose. The authors also analyzed the amplitude of the EEG rhythms (standard frequency ranges), evaluated changes in hemispheric asymmetry coefficients of frontal and central alpha and beta1 rhythms as EEG correlates of imaginary activity.
Results. Imaginary movements caused a decrease in the amplitude of alpha, beta1, theta and delta rhythms on EEG in all trial subjects. The intensity of observed changes in right- and left-handers differed in symmetrical leads. As for frontal and central alpha and beta1 rhythms, which marked changes in the EEG pattern during imaginary movements, right-handers demonstrated that their depression level in symmetric cortical areas depended significantly on the imaginary movements of leading and non-leading legs and dominated in left or right hemispheres, respectively. For left-handers, changes in alpha and beta1 waves during imaginary movements of leading and non-leading legs did not differ significantly and in both cases dominated in the right hemisphere.
Conclusion. Thus, the intra- and inter-hemispheric dynamics of the EEG pattern, while forming the concept and program of complex motor leg actions in left-handers, is alternative in comparison to right-handers.

Keywords: EEG, alpha rhythm, beta1 rhythm, imaginary leg movements, hemispheric asymmetry, right-handers, left-handers.
CHOLINERGIC SYSTEM RESPONSE TO STRESS AND DEPRESSION
Authors: Gaynutdinov M.Kh. , Khakimova D.M. , Kalinnikova T.B. , Shagidullin R.R.
Published: March 2019

The paper presents a summary of results considering cholinergic hypothesis on the central processes of human stress response and depression caused by chronic social stress. These studies include both the work of clinicians, who are examining pathogenesis of depression, and experiments with rodents. The authors also consider the history of stress response discovery in humans and vertebrates. The paper analyses the results of early studies (1980s-1990s), which led to the hypothesis on the key role of brain cholinergic system in nonspecific stress response of the whole multicellular organism of humans and rodents. Special attention is paid to the latest ideas on acetylcholine as the most powerful neuromodulator in the brain. Acetylcholine is said to transmit large volumes of information. The authors conducted the summary of experimental and clinical studies showing that the primary reaction of humans and rodents under stress is manifested in the activation of brain cholinergic transmission, but not in subsequent changes in serotonergic system functioning. The paper analyses numerous studies, the result of which confirmed the cholinergic hypothesis on stress and depression. These facts are as follows: firstly, the increase in the acetylcholine level in the brain or in the hippocampus (physostigmine injection) causes similar changes in the behavior and physiological state of rodents under stress; secondly, single-time stress increases the acetylcholine level in several areas of the brain, thus, correlating to adaptive changes in behavior; thirdly, chronic stress that causes disturbances in rodent behavior, which are similar to depression, is accompanied by an increase of the acetylcholine level in the brain. In general, the authors come to the conclusion that ideas on the key role of cholinergic system in stress response can serve as a scientific basis for further research on the depression mechanisms both clinically and experimentally

Algorithm for Applying Statistics and Scientometric Analysis to Identify Innovative Areas of Focus in Scientific Knowledge in Labour Economics
Authors: Bashina O. E. , Matraeva L. V. , Vasyutina Ye. S.
Published: March 2019

The modern Digital Universe changes and expands at a speed that every two years double the amount of data. It leads to a situation when huge accumulated flows of information can no longer be covered by traditional scientific search and built into a relevant scientific research framework. The authors argue that there is a need for using modern statistics and scientometric application packages for solving research tasks in the primary trends of the information economy. The article presents a comparative analysis of various scientometric programs and describes a new approach to identifying and visualizing patterns and transient regularities in the scientific literature on the basis of a study of global publication flows in the last 25 years in the subject area of «labour economics» represented in the Web of Science.

The authors conceptualize and visualize scientific domain of «labour economics» within the framework of the timing diagram of the evolution of research fronts. They introduce the search algorithm for active research fronts in the global information flow using CiteSpace V.0 and highlight the most critical trends and principal points of research clusters for the past decade on labour economics and its core studies. The paper determines most perspective citation spikes that could potentially become the center of new scientific knowledge in this area and outlines opportunities for future research.
Transformation of 2000-2020 Population Census Programmes in the CIS States as a Response to Changing Needs of the Society
Authors: Zbarskaya I. A. , Selishcheva G. G.
Published: March 2019

In 2018 CIS-Stat surveyed national statistical oﬃces of all member states of the Commonwealth regarding the list of topics they plan to include in the 2020 census programmes. This material is a result of thorough analysis of the information presented along with questionnaires from 2000 and 2010 census round. The article covers core census topics that the CIS member-states plan to include in their census programmes of the 2020 round. Population census topics are designed to maintain continuity with the previous censuses, to meet national information needs and are consistent with international recommendations. Much of the national population census programmes preserve the traditional structure. However, every round brings own features given the information needs of every state of the Commonwealth.

Pilot population censuses are conducted in order to test methodological and technical solutions. Pilot censuses have currently been completed inBelarus(in 2017),Azerbaĳan,Kazakhstan,RussiaandTajikistan(in 2018). This material presents general characteristics of testing of materials and documents included in the core headings of the census programme. All of them have commonalities as well as own features that serve the information needs of a country. The authors explore the following sections of census programme: “Population to be enumerated, household and family characteristics”, “Demographic and ethno-cultural characteristics”, “Marital status and fertility”, “Geographical and migration characteristics”, “Characteristics of persons, temporarily present in the country”, “Educational and economic characteristics”, “Other population and household characteristics”.

Population censuses in the CIS countries continue to be one of the pillars of data collection on the number and socio-demographic, economic and ethno-cultural characteristics of the population of a country; at the same time, some topics - educational attainment, marital status, language and ethnicity - can only be investigated in a census of population.

The 2020 census round in the CIS countries stands out as having agreed upon methodology for socio-demographic characteristics, particularly information on migration and work force. Harmonized methodology will allow national statistical offices to more precisely determine the flows and volume of international migration, along with the total size of the Commonwealth labour market amidst the fast approaching census date.

Quelques notes sur le statut du métalangage chez Jacques Lacan
Authors: Arrivé Michel
Published: March 2019

After a definition of the notions of (fr.) métalangage, métalangue, métadiscours and a taxonomy of the different kinds of metalanguages (logical, linguistic and, among the latter, internal and external) the paper discusses the metalinguistic status of negation. One comes then to a description of Lacan's evolving attitude regarding metalanguage : from an explicit (though ambiguous) assignment of its place, to a final attempt to reassign it a place, and through the stage of what is called here the (de)negation of metalanguage, translation -borrowed from Laplanche and Pontalis' dictionary -from the ambiguity of the freudian term Verneinung. From a purely linguistic standpoint, the article suggests that what Lacan's criticism questions is metalanguage as a system. The specifically psychoanalytical aspects of the problem are considered at the end of the paper.
L'articulation du sémantique et du conceptuel. A propos de l'article de M. Bierwisch : "La nature de la forme sémantique d'une langue naturelle"
Authors: Reis Marga
Published: March 2019

This paper is a commentary on Bierwisch's article (DRLAV, Revxie de Linguistique 33 (1985)) "On the nature of semantic form in natural language". The commentary provides background information concerning Bierwisch's conception of language and linguistics (§ 1), and examines, specifically, Bierwisch's views concerning the level of semantic form , the major aspects of discussion being : the conceptual part of 'meaning' (§ 2.1 and 2.2), the arguments for positing a semantic level, and their validity (§ 2.3). Although these are found to be inconclusive, a positive overall evaluation of Bierwisch's approach is given and defended in (§ 3) .

The paper insists upon the amazing qualitative mutation which has been achieved in the recent development of phonetics (no longer to be separated from phonology). Both substance and form are to be taken into account to analyse encoding as well as decoding. The paper compares different theoretical approaches and, in relation with them, different technical simulations in the field of Speech Recognition and Speech Synthesis, which lay the foundations for the so-called Man-Machine Communication.
Inachèvements
Authors: Grunig Blanche-Noëlle
Published: March 2019

The author lays stress on the fact that gaps, empty places, blanks, and also stops and cuts are to be taken into account in many fields of linguistic research and should give rise to the formulation of theoretical assumptions. She emphasizes that every hypothesis about "emptiness" can scarcely be conceived without a simultaneous and solidary hypothesis about "completeness" and "full forms" (morphological and syntactical microstructures ; textual, pragmatical or cognitive macrostructures - which may have to remain unspecified as to their verbal substance). Some morphological and syntactical phenomena are briefly analysed as well as some particular types of short "texts" (joke, advertisements, telegrams). Conversational stops lead the author to propound a dynamical type of explanation, making use of "real time" and of operations which are tentatively supposed to represent mental processes.

The main characteristics of spoken language such as described by Hermann Wunderlich (1893 ; 1894 ; 1897 ; 1898) are the tendency to economy and on the other hand the tendency to redundancy. Wunderlich describes spoken language from the speaker's point of view.
Vie des mots et science des significations : Arsène Darmesteter et Michel Bréal
Authors: Delesalle Simone
Published: March 2019

On veut montrer dans ce texte l'importance de l'oeuvre de deux auteurs français : Arsène Darmesteter et Michel Bréal, qui élaborèrent une analyse du langage ayant pour centre le sens, à la fin du XIXe siècle, après la grammaire comparée et parallèlement aux thèses néo-grammairiennes. Par delà leurs points communs on veut souligner leurs différences : Darmesteter travaille sur le lexique, en introduisant les tropes dans sa description, tandis que Bréal élargit la perspective (lexique, groupes de mots, syntaxe, élément subjectif du langage) et essaie de formuler des lois sémantiques tout en cherchant les causes des changements de sens. Ces travaux ont certainement influencé Bally et Saussure, et ont amené l'analyse du langage à devenir une science humaine.
Le principe de substitution de Leibniz : condition nécessaire et suffisante de l'opacité référentielle ?

Published: March 2019

The aim of this paper is to show, on the basis of a study of some semantical paradoxes, that the Leibniz's principle of substitutivity is not the necessary and sufficient condition allowing to decide of the referential opacity of a context. It does not necessarily detect within a statement the presence of a referential opacity and also reacts to another parameter than the opacity : the underdetermination.

In recent times, many biologically relevant building blocks such as amino acids, peptides, saccharides, nucleotides and nucleosides, etc. have been prepared by mechanochemical synthesis. However, mechanosynthesis of lipids by ball milling techniques has remained essentially unexplored. In this work, a multistep synthetic route to access mono- and diacylglycerol derivatives by mechanochemistry has been realized, including the synthesis of diacylglycerol-coumarin conjugates.
DISCONTINUOUS FUNCTIONS IN GALE ECONOMIC MODEL
Authors: Bula I.
Published: March 2019

The concept of a general economic equilibrium based on balance of supply and demand has played a central role in theoretical economics since very beginning. One of the basic assumptions in mathematical modelling of the equilibrium economic model is the continuity of functions describing the model. This article analyses simplified version of Gale model from year 1955 by weakening the condition of strict convexity and continuity of utilities functions and proving existence of quasi‐equilibrium in generalized Gale model.

MATHEMATICAL SIMULATION AND NUMERICAL METHOD FOR SOLVING GEOMIGRATION PROBLEM
Authors: Gromyko G. , Zayats G.
Published: March 2019

In the present paper a two‐dimensional boundary value problem of geomigration taking into account convection transfer, hydrodynamic dispersion, molecular diffusion and absorption is considered. The problem is described by the system of two differential equations for the level of ground water [3] and the concentration of the contaminant in ground water [4]. For numerical solving we used the finite difference schemes taking into account the characteristic properties of the problem. The calculations were produced in conformity with concrete hydro‐geological conditions. The obtained solutions are used for prognosis of contaminant migration in ground water.

NECESSARY OPTIMALITY CONDITIONS FOR NONSMOOTH VECTOR OPTIMIZATION PROBLEMS
Authors: Torre Davide La
Published: March 2019

In this paper we introduce a notion of generalized derivative for nonsmooth vector functions in order to obtain necessary optimality conditions for vector optimization problems. This definition generalizes to the vector case the notion introduced by Michel and Penot and extended by Yang and Jeyakumar. This generalized derivative is contained in the Clarke subdifferential and then the corresponding optimality conditions are sharper than the Clarke's ones.
ON NUMERICAL SIMULATION OF LIQUID POLYMER MOULDING
Authors: Čiegis R. , Iliev O.
Published: March 2019

In this paper we consider numerical algorithms for solving the system of nonlinear PDEs, arising in modeling of liquid polymer injection. We investigate the particular case when a porous preform is located within the mould, so that the liquid polymer is flowing through a porous medium during the filling stage. The nonlinearity of the governing system of PDEs is due to the non‐Newtonian behavior of the polymer, as well as due to the moving free boundary. The last is related to the penetration front, and a Stefan type problem is formulated to account for it. A finite‐volume method is used to approximate the given differential problem. Results from numerical experiments are presented.

We also solve an inverse problem and present algorithms for determination of the absolute preform permeability coefficient for the case when the velocity of the penetration front is known from the measurements.

In both considered cases (direct and inverse problems) we emphasize on the specifics related to the non‐Newtonian behavior of the polymer. For completeness, we discuss also the Newtonian case. Results of some experimental measurements are presented and discussed.

We derive direct-measurement gas-phase metallicities of

for 14 low-mass emission-line galaxies at 0.3 < z < 0.8 identified in the Faint Infrared Grism Survey. We use deep slitless G102 grism spectroscopy of the Hubble Ultra Deep Field, dispersing light from all objects in the field at wavelengths between 0.85 and 1.15 μm. We run an automatic search routine on these spectra to robustly identify 71 emission-line sources, using archival data from Very Large Telescope (VLT)/Multi-Unit Spectroscopic Explorer (MUSE) to measure additional lines and confirm redshifts. We identify 14 objects with 0.3 < z < 0.8 with measurable [O iii]λ4363 Å emission lines in matching VLT/MUSE spectra. For these galaxies, we derive direct electron-temperature gas-phase metallicities with a range of

⊙, we construct a mass–metallicity (MZ) relation and find that the relation is offset to lower metallicities compared to metallicities derived from alternative methods (e.g., R
23, O3N2, N2O2) and continuum selected samples. Using star formation rates derived from the Hα emission line, we calculate our galaxies’ position on the Fundamental Metallicity Relation, where we also find an offset toward lower metallicities. This demonstrates that this emission-line-selected sample probes objects of low stellar masses but even lower metallicities than many comparable surveys. We detect a trend suggesting galaxies with higher Specific Star Formation (SSFR) are more likely to have lower metallicity. This could be due to cold accretion of metal-poor gas that drives star formation, or could be because outflows of metal-rich stellar winds and SNe ejecta are more common in galaxies with higher SSFR.
Pre-eruption Processes: Heating, Particle Acceleration, and the Formation of a Hot Channel before the 2012 October 20 M9.0 Limb Flare
Authors: Hernandez-Perez Aaron , Su Yang , Veronig Astrid M. , Thalmann Julia , Gömöry Peter , Joshi Bhuwan
Published: March 2019

We report a detailed study of the pre-eruption activities that led to the occurrence of an M9.0 flare/CME event on 2012 October 20 in NOAA AR 11598. This includes the study of the preceding confined C2.4 flare that occurred on the same AR ∼25 minutes earlier. We observed that the M9.0 flare occurred as a consequence of two distinct triggering events well separated in time. The first triggering episode occurred as early as ∼20 minutes before the onset of the M9.0 flare, evidenced by the destabilization and rise of a pre-existing filament to a new position of equilibrium at a higher coronal altitude during the decay phase of the C2.4 flare. This brought the system to a magnetic configuration where the establishment of the second triggering event was favorable. The second triggering episode occurred ∼17 minutes later, during the early phase of the M9.0 flare, evidenced by the further rise of the filament and successful ejection. The second trigger is followed by a flare precursor phase, characterized by nonthermal emission and the sequential formation of a hot channel as shown by the SDO/AIA DEM (differential emission measure) maps, the RHESSI X-ray images and spectra. These observations are suggestive of magnetic reconnection and particle acceleration that can explain the precursor phase and can be directly related to the formation of the hot channel. We discuss the triggering mechanisms, their implications during the early and precursor phases and highlight the importance of early activities and preceding small confined flares to understand the initiation of large eruptive flares.

Published: March 2019

Introduction: In the classic treatment of Trichomonas vaginalis infection, although metronidazole has been used since the 1960s, there has been an increase in MTZ-resistant T. vaginalis strains and failure in the treatment of trichomoniasis causes serious concerns. Therefore, the present study aimed to investigate the in vitro antitrichomonal activities of extracts (ethanol and total alkaloid) and pure compounds (chrysosplenetin, dictamnine, gamma-Fagarine, skimmianine) of H. myrtifolium against T. vaginalis.

Methodology: H. myrtifolium was collected from the town of Honaz in Denizli, located in the Aegean region of Turkey, and preparation of extracts and isolation and structure elucidation of pure compounds were performed. Later, different concentrations of extracts and pure compounds were incubated with T. vaginalis trophozoites isolated from Turkey, which are known to be sensitive to metronidazole.

Results: It was found that ethanol extract caused a more effective lysis on T. vaginalis trophozoites compared with total alkaloid extract (P < 0.05). No compounds except for furoquinoline alkaloid skimmianine prepared above 37.5 µg/mL were found to have any inhibitory effect on T. vaginalis trophozoites.

Conclusion: The ethanol extract of H. myrtifolium and skimmianine can be considered as potential candidates for antitrichomonal drug development.

Published: March 2019

Introduction: The incidence of diabetes mellitus is increasing rapidly in India. In addition to well-known complications, diabetes increases the risk for hospitalization and death from severe acute respiratory infection (SARI) and influenza. Here we examined the impact of SARI and influenza in Indian adults with diabetes.

Methodology: This was a single-center, active surveillance study conducted in Jammu and Kashmir State, India, during the 2015–2016 and 2016–2017 influenza seasons. Adults hospitalized for SARI and receiving at least one diabetes medication were included. Demographics, health care use, and direct costs were collected from medical records and interviews of patients or caregivers. Indirect costs were estimated based on lost earnings and WHO-CHOICE estimates for hospital costs.

Results: The study included 192 patients with type 2 diabetes. Median age was 66 years, median body mass index was 26.6 kg/m2, and most patients had comorbidities, especially hypertension and cardiovascular disease (83.9%). Only 32.2% regularly monitored blood glucose or hemoglobin A1C, and median values at admission indicated poor glycemic control for most. Influenza was detected in 8.9% of cases. The median hospital stay for SARI was 8 days, and 22 patients (11.4%) died. Median total costs associated with hospitalization were US$710 (interquartile range, $539–$1067) for SARI patients and US$716 ($556–$1078) for influenza patients, mostly (~75%) from indirect costs.

Conclusions: Adults with diabetes in India hospitalized with SARI or influenza are generally older, in poor health, and suffer from poor glycemic control. The costs for their hospitalization and care are substantial.

Three genomic regions (nrITS, nrLSU/28S and rpb2) have been sequenced in order to reinforce the recognition of the new species and to elucidate its taxonomic affiliation within Neoboletus.
A fast and memory-efficient two-pass connected-component labeling algorithm for binary images
Authors: BATAINEH BILAL
Published: March 2019

Connected-component labeling is an important process in image analysis and pattern recognition. It aims to deduct the connected components by giving a unique label value for each individual component. Many algorithms have been proposed, but they still face several problems such as slow execution time, falling in the pipeline, requiring a huge amount of memory with high resolution, being noisy, and giving irregular images. In this work, a fast and memory- efficient connected-component labeling algorithm for binary images is proposed. The proposed algorithm is based on a new run-base tracing method with a new resolving process to find the final equivalent label values. A set of experiments were conducted on different types of binary images. The proposed algorithm showed high performance compared to the other algorithms.
A novel hybrid teaching-learning-based optimization algorithm for the classification of data by using extreme learning machines
Authors: SEVİNÇ ENDER , DÖKEROĞLU TANSEL
Published: March 2019

Data classification is the process of organizing data by relevant categories. In this way, the data can be understood and used more efficiently by scientists. Numerous studies have been proposed in the literature for the problem of data classification. However, with recently introduced metaheuristics, it has continued to be riveting to revisit this classical problem and investigate the efficiency of new techniques. Teaching-learning-based optimization (TLBO) is a recent metaheuristic that has been reported to be very effective for combinatorial optimization problems. In this study, we propose a novel hybrid TLBO algorithm with extreme learning machines (ELM) for the solution of data classification problems. The proposed algorithm (TLBO-ELM) is tested on a set of UCI benchmark datasets.

A bitmap-based index is an effective and efficient indexing method for answering selective queries in a read- only environment. It offers improved query execution time by applying low-cost Boolean operators on the index directly, before accessing raw data. A drawback of the bitmap index is that index size increases with the cardinality of indexed attributes, which additionally has an impact on a query execution time. This impact is related to an increase of query execution time due to the scanning of bitmap vectors to answer the queries. In this paper, we propose a new encoding bitmap index, called the HyBiX bitmap index. The HyBiX bitmap index was experimentally compared to existing encoding bitmap indexes in terms of space requirement, query execution time, and space and time trade-off for equality and range queries. As experimental results, the HyBiX bitmap index can reduce space requirements with high cardinality attributes with satisfactory execution times for both equality and range queries. The performance of the HyBiX bitmap index provides the second-best results for equality queries and the first-best for range queries in terms of space and time trade-off.
A novel accuracy assessment model for video stabilization approaches based on background motion
Authors: HOSSAIN MD ALAMGIR , NGUYEN TIEN-DUNG , HUH EUI NAM
Published: March 2019

In this paper, we propose a new accuracy measurement model for the video stabilization method based on background motion that can accurately measure the performance of the video stabilization algorithm. Undesired residual motion present in the video can quantitatively be measured by the pixel by pixel background motion displacement between two consecutive background frames. First of all, foregrounds are removed from a stabilized video, and then we find the two-dimensional flow vectors for each pixel separately between two consecutive background frames. After that, we calculate a Euclidean distance between these two flow vectors for each pixel one by one, which is regarded as a displacement of each pixel. Then a total Euclidean distance of each frame is averaged to get a mean displacement for each pixel, which is called mean displacement error, and finally we calculate the average mean displacement error. Our experimental results show the effectiveness of our proposed method.

Published: March 2019

The potential ofTenebrio molitor as an alternative protein source for food applications was investigated by using several conventional (blanching and freeze drying) and non-conventional (high pressure) processing techniques. Some of the challenges in product development are the browning effect of minced mealworms and the texturizing capacity after mincing. Both blanching and high pressure processing at 400 and 500 MPa proved to be effective in inactivating enzymes responsible for browning. However, the inactivation process was accompanied by a significant decrease in texturizing properties of the minced mealworms, especially when blanching was applied. Also when applying pressure, the texture changed from stronger (samples treated at lower pressures) to weaker (samples treated at higher pressures). Minced fresh or freeze dried mealworms provided textures with a reasonable strength and elasticity, but browning still occurred. Nevertheless, this browning could be slowed down by applying air tight packaging to prevent oxidation.
Development and Evaluation of a Mental Health Care System at a Japanese Company
Authors: Ariyoshi Hiromi
Published: March 2019

Compared with other industrialized countries, the suicide rate in Japan is high. The purpose of this research was to evaluate the mental health care offered at a newspaper facing organizational restructuring and with an aging work force. The Health and Safety Committee played a central role in the creation and application of a new mental health care system. This plan, developed to meet the on-site dynamics of the company, was based on the Ministry of Health, Labour and Welfare's “Guide for Workers' Mental Health Promotion in the Workplace.” Executive officers' roles were defined at the directors' meetings, and the Health and Safety Committee held Listening Skills Seminars for executive personnel. As a result, the mental health care system functioned effectively and fostered the care of two presenting employees (i.e., one with slight depression with chronic lumbago and the other with alcohol dependency). In addition, the number of workers who took 4 or more days of sick leave decreased from 31 of 190 in 1996 to 5 of 108 in 2004, with no psychologically related absences. Moreover, the number of industrial injuries declined from 8 cases in 1996 to 0 cases in 2004, and no occupational deaths or early retirements occurred between the fiscal years of 1996 and 2004. As a result of this research at the company, a worksite where repeated large-scale organizational restructuring has occurred, the mental health care system functioned effectively and contributed to a decrease in the rate of sick leave taken by workers.

Published: March 2019

The development of computer technology has reshaped the form and philosophy of landscape design, as evidenced by the growing importance of computer-aided design (CAD) in this area. This paper attempts to apply 3D visualization in the teaching of landscape design. For this purpose, three CAD teaching tools were selected, namely, AutoCAD, 3D Max and SketchUp, and subjected to theoretical analysis and teaching practice. The research results show that AutoCAD can guide the landscape design teaching from conception to positioning, 3D Max can upgrade the teaching form from 2D to 3D in the later phase, and SketchUp sup-ports the entire process of landscape design. In addition, the author summarized the specific process of supporting landscape design teaching with SketchUp. This research enriches the results on the application of CAD in landscape design teaching and has certain theoretical and practical significance.

Published: March 2019

To improve the English proficiency of college students, this paper attempts to promote autonomous English learning among these students using artificial intel-ligence technology. Specifically, the principles, features and application fields of artificial intelligence were introduced in details, and the requirements, structure, database and processes of autonomous English learning systems were discussed at length. On this basis, the backpropagation (BP) neural network, a typical artifi-cial intelligence technique, was selected to design the modules of the autonomous English learning system for college students. The proposed system was then im-plemented in integrated open environment of Visual Studio, the architecture of the browser/server system and the SQL Server database on the Windows platform. The results show that the proposed system provides college students with intelli-gent and open self-evaluation tests and effective learning feedbacks. The research findings shed new light on improving the English learning of college students and reliving the pressure on college English teachers.

Published: March 2019

Navigation is one of the typical problem domains occurred in studying swarm robot. This task needs a special ability in avoiding obstacles.  This research presents the navigation techniques using type 1 fuzzy logic and interval type 2 fuzzy logic. A comparison of those two fuzzy logic performances in controlling swarm robot as tools for complex problem modeling, especially for path navigation is presented in this paper.  Each hierarchical of fuzzy logic shows its advantages and disadvantages.  For testing the robustness of type-1 fuzzy logic and interval type-2 fuzzy logic algorithms, 3 robots for the real swarm robot experiment are used.  Each is equipped with one compass sensor, three distance sensors, and one X-Bee communication module.  The experimental results show that type-2 fuzzy logic has better performance than type-1 fuzzy logic.

Drawing value curves: lessons from financial statements of the world’s biggest manufacturing corporations
Authors: Fróes de Borja Reis Cristina , Barroso de Souza André
Published: March 2019

The aims of this paper are, first, to discuss the theory and the data for understanding global value chains (GVC); and second, to analyze the financial statements of the top manufacturing transnational corporations (TNC) in order to learn about value curves. The main contribution is the cost analysis through the financial statements of more than 250 public-listed manufacturing TNC. The conclusions are that smiles are not necessarily a fine image for GVC’ value-added curves, but more likely in high technology-intensive industries. Companies and industries whose expenditures are more concentrated in intangible activities, investing more in research & development (R&D) and/or in selling, general and administrative expenses (SG&A), tend to present higher margins than average.JEL classification: O14, O33, F14, L80.
Citizen Participation via Mobile Applications
Authors: Beutelspacher Lisa , Mainka Agnes , Siebenlist Tobias
Published: March 2019

Participatory smartphone apps empower citizens to interact with the city's administration. The purpose of this case study is to investigate the current state of participatory apps in Germany. Within this study, we examined 248 applications aimed at strengthening citizen participation. These apps were found in Google Playstore and Apple Appstore using search terms extracted from the relevant literature. Many of the apps give users the opportunity to report problems within their cities, such as broken street lamps or potholes. The information created and disseminated by the citizens through the app mainly includes the topics “mobility” and “environment.” Information provided by the city itself is much more diverse. Topics such as “Points of Interest,” “News and Events,” “Government” or “City Services” can be identified here. In the southern part of Germany, there is a significantly larger number of municipalities which have a citizen participation app. None of the apps examined uses gamification, although the use of game elements is very promising to foster the engagement and motivation of citizens.
