Authors: Prasetyo Yuli Agung , Rusdiana Taofik , Abdassah Marline
Published: January 2019

Osteoarthritis is a chronic degenerative disease of the joints that usually treated by NSAID drugs in the long term leading to cardiovascular and gastrointestinal disorders. Glucosamine is a precursor in the formation of progression of joint which have not a significantly side effect. The problem in glucosamine administration occured when it is administered through the oral route resulting in first pass metabolism, while when it is administered via intavena route resulting in insulin resistance. Those problems can be solved by developing glucosamine into nanoglucosamine in order to increase the enzymatic stability which will protect the active ingredient from diminishing by the first pass effect hence the dose can be reduced, consequenlty it will reduce the insulin resistance, and increase the permeation. In this study, the nanoparticles of glucosamine with chitosan polymer and crosslinker alginate was prepared by the ionic gelation method with the principle of continued cross forming polyelectrolyte complexes. This study started from preformulation such as solubility and identify study by FTIR, then the formulations of chitosan: glucosamine: alginate = 5:1:1 (volume ratio) with the variation of concentration in the FI (chitosan: glucosamine: alginate = 0.08 %: 0.1%: 0.08%) and FII (chitosan: glucosamine: alginate = 0.1%: 0.1%: 0.08%). Results of nanoparticle characterization by particle size analyzer in the FI showed the better formula indicating a foggy coloid, no precipitation, the pH was 2.90±0.05, and the percent transmittance was  99.35%. The distribution of particle size, polydispersity index, and zeta potential for the formula I were 76.0 ± 21.8 nm; 0.300; and -0.30 mV, respectively. It could be concluded that the nanoparticle system of glucosamine can be better prepared from the 0.08% of chitosan, 0.1% of glucosamine and 0.08% of alginate.Keywords: alginate, chitosan, ionic gelation method, glucosamine nanoparticle
Influence of Emollient on the Preparation and stability of Sodiun Ascorbyl Phospate Cream
Authors: Mardhiani Yanni Dhiani , Azhari Deny Puriyani , Wulansari Silviana
Published: January 2019

As a type of cosmetic preparation products, cream dosage form is widely used with the addition of active substances having antioxidant activities, such as vitamin C and its derivatives. Sodium ascorbyl phosphate (SAP) can be used in topical formulation due to its more stable properties than ascorbic acid. However, it is difficult to deliver SAP into the dermis in a suficient dose. To overcome the problem, occasionally we can add a penetration enhancer. In some literature, emollients that often added in cosmetic preparations also have another effect as a penetration enhancer. The purpose of this research was to observe wether emollient addition could influence the penetration of SAP in the cream formulation or not. SAP was formulated into four formulations with three different emollients: dimethicone (F1), capric triglyceride (F2), and isopropyl myristate (F3) and a formulation without the addition of emollients (F4). The diffusion test was performed by Franz's diffusion cell method using male wistar rat’s abdominal membrane as a standard model of the skin barrier. The result of stability test showed that SAP cream was stable at room temperature but unstable on freeze thaw condition described by significant different values for all formulas. Nonetheless, the diffusion test showed that F2 with the capric triglyceride as emollient had the highest ability to pass SAP through the membrane, followed by isopropyl miristate. We concluded that emollient addition could influence the penetration of the cream of SAP.Keywords: vitamin c, ascorbic acid, sodium ascorbyl phospate, emollient, penetration enhancer
Monitoring of Moth Pests in Apple Tree Orchard
Authors: Paulen Oleg , Kobolka Radoslav
Published: January 2019

The work suggests importance of monitoring apple tree pests from moth group in growing conditions of Nitra, Slovakia. In 2014 there was observed occurrence of moths e.g. Codling moth (Cydia pomonella L.), Appleseed moth (Grapholita lobarzewskii Now.), Hawthorn berry moth (G. janthinana Dup.), and Summer fruit tortrix moth (Adoxophyes orana Fish. v. Roesl.) in the apple tree orchard located in the Botanical Garden of SUA in Nitra with help of pheromone traps. The date of first generation occurrence of Codling moth, Appleseed moth and Summer fruit tortrix moth was recorded on April 23. All the pests showed two peaks of flight activity, but with Hawthorn berry moth three periods of higher occurrence were recorded. The course of temperatures influenced number of pests trapped in traps remarkably. The number of pest individuals was highly influenced by rainy weather and lower temperatures in months when there was expected their highest harmfulness. The recorded values might be influenced by plant species diversity of the experimental orchard as well as that of the surrounding area.

Published: January 2019

Introduction: Xanthogranulomas are rare, benign, usually asymptomatic, cutaneous tumors most frequently seen in children (juvenile xanthogranulomas). Some lesions can be found accidentally at randomly performed cerebral computer tomography (CT) or magnetic resonance imaging (MRI) or even on autopsy.

Case report: We present the case of a 44 year-old woman, known with a thrombophilic disorder (PAI-1 gene mutation, MTHFR C677T and A1298C) on chronic anticoagulant treatment. The onset of symptoms was in 2010, when she presented paresthesia and lower limbs weakness. Two years later the patient presents with severe intermittent headache and left hemicrania and a cerebral angio-MRI is performed showing a left postero-inferior cerebellar artery aneurysm and two choroid plexus intraventricular masses in the lateral ventricles. The patient developed a new symptom, dysarthria in 2014 and in 2015 has multiple episodes of loss of consciousness, interpreted as epileptic seizures. Routine blood tests were within normal range, except for a high cholesterol level. The patient was tested for autoimmune, infectious, endocrine and metabolic diseases that were negative. Surgical treatment and biopsy from the lesion was proposed, however the patient refused both procedures.

Conclusions: There is an association between xanthogranulomas localization and the choroid plexus, the most frequent CNS origin being in the trigon of the lateral ventricle. Our case does not resemble with any other case published, mostly because the unusual presentation, symptomatology and the association between xanthogranulomas, thrombophilia and postero-inferior cerebellar artery aneurysm which were never reported before in other cases of xanthogranulomas from the literature.

Published: January 2019

Recently have been reported methods to deliver a digital filter from an analog active filter, described only by its circuits diagram. The proposed approaches have been implemented in MATLAB and Python, and they were based on state-space conversion from analog to digital domain. Based on the Python approach, we show in this paper how to compute the transfer function of a large order analog active filter. The analog filter is described only by its circuits diagram. Finally, the analog filter is converted to the corresponding digital filter, having similar frequency gain and phase characteristics.

The impact of clime is important on many aspects of life such as the development of tourism and human health, tourists always wanted to choose the most convenient time and place that have appropriate weather circumstances. The goal of this study is to specify the preferable months (time) for tourism in Jordan regions. Neural network has been utilized to analyze several parameters of meteorologist (raining, temperature, speed of wind, moisture, sun radiation) by analyzing and specify tourism climatic index (TCI) and equiponderate it with THI index. The outcomes of this study shows that the finest time of the year to entice tourists is “ April” which is categorized as to be “extraordinary” for visitors. TCI outcomes indicates that conditions are not convenient for tourism from July to August because of high temperature.
The ethical problems of death pronouncement and organ donation: A commentary on Peter Singer’s article
Authors: Ziemiński Ireneusz
Published: January 2019

The article is a critical commentary on Peter Singer’s thesis that the brain death definition should be replaced by a rule outlining the conditions permitting organ harvesting from patients who are biologically alive but are no longer persons. Largely agreeing with the position, I believe it can be justified not only on the basis of utilitarian arguments, but also those based on Kantian ethics and Christianity. However, due to the lack of reliable methods diagnosing complete and irreversible loss of consciousness, we should refrain from implementing upper brain death into medical practice. Organs also should not be harvested from people in a persistent vegetative state or from anencephalic children, for similar reasons. At the same time, patients who suffered from whole-brain death should not be artificially sustained; in light of current knowledge they can be declared dead and become organ donors.
The Effect of Land Acquisition Policy on Market Trends in Hungary
Authors: Orlovits Zsolt , Kovács László
Published: January 2019

The aim of the present paper is to provide a comprehensive overview of the major regulations related to the acquisition and ownership of agricultural and forestry lands in Hungary and the effect of these regulations on the trends and changes in trade and ownership structure. The four pivotal points regarding policy–making have been the following: (1) maintaining national ownership of agricultural lands, (2) preventing the registration of ownership when the aim of the transaction is speculation, (3) maintaining the limitation and strict regulations on the possibilities for new acquisitions by corporately owned farms, (4) supporting the acquisition and usage of agricultural lands by privately and family owned farms. In order to achieve these aims, the government of Hungary decided upon a framework for agricultural land acquisition and ownership that integrates a number of rules and limitations already applied by land administration authorities in other EU member countries. However, their systematic and cumulative use raises major questions in the application of the relevant laws in real–life situations; in addition, there are serious concerns about their compatibility with EU principles on legislation and jurisdiction(1). This paper summarises typical situations to illustrate the controversies of the regulations related to agricultural land acquisition and use in Hungary.

Authors: Huňáková K. , Hluchý M. , Kuricová M. , Ševčík K. , Rosocha J. , Ledecký V.
Published: January 2019

Exosomes are nanovesicles that are involved in inter-cellular communication and are secreted by many types of cells. Exosomes secreted by stem cells can effectively transport bioactive proteins, messenger ribonucleic acids (mRNAs) and microribonucleic acids (miRNAs) organelles and play important roles in intercellular communication and the regulation of tissue regeneration. This transfer of bioactive molecules plays a main role in: tumor invasion and metastasis, immune and inflammation modulation, epithelial-mesenchymal transition and neurobiology. Mesenchymal Stem Cells (MSC) exosomes provide new perspectives for the development of an off-the-shelf and cell-free MSC therapy for the treatment of cartilage injuries and osteoarthritis. This report describes the progress in exosome studies and potential clinical use for osteoarthritis treatment.
Canine Ocular Thelaziosis in Slovakia a Case Report
Authors: Balicka A. , Lapšanská M. , Halán M. , Trbolová A.
Published: January 2019

Thelaziosis is a parasitic disease of the eye that has become more common in Europe over the last twenty years. It is caused by a nematode, order Spirurida, family Thelaziidae. The transmission of this parasite occurs by the dipteran flies. Thelazia callipaeda occurs in the conjunctival sac, under the third eyelid or in the lacrimal ducts, causing blepharospasm, conjunctivitis, keratitis and sometimes corneal ulceration. Thelaziosis is a zoonotic disease. It occurs in humans, domestic animals and wildlife. Between 2016 and 2018 three cases of canine ocular thelaziosis occurred in dogs admitted to the Small Animals Clinic in Kosice, Slovakia. In all cases, the systemic and local treatments were administered. The parasites were removed from the conjunctival sac. The identification of Thelazia callipaeda was performed by microscopic examinations.
Molecular Detection of Cryptosporidium Species in Domestic Ducks Sold for Food in Nigerian Live Bird Markets
Authors: Ayinmode A. B. , Falohun O. O.
Published: January 2019

Cryptosporidium infections has been reported in several avian species including chickens, pigeons and game birds where these infections had been identified to cause either enteric or respiratory diseases. However, little data exists on the molecular characterization of Cryptosporidium species in ducks, especially those in frequent contact with humans. The aim of this study was to detect the Cryptosporidium species infecting domestic ducks in two major live bird markets. A total of 109 fresh faecal samples were collected from all the ducks available on sale in the two markets. The detection of Cryptosporidium species was conducted by microscopy. All positive samples were confirmed by the nested PCR amplification and the nucleotide sequencing of the 18S rRNA genes. The results demonstrated that the prevalence of Cryptosporidium infection in ducks using microscopy was 11.0 % (12/109). There was a higher prevalence 14.0 % (7/50) in ducks from Ibadan compared with those 8.5 % (5/59) obtained from Oyo town. All positive samples by microscopy were also positive using the nested PCR and the DNA sequencing of the secondary PCR products from the 18S rRNA genes which revealed the presence of Cryptosporidium parvum. This study revealed that natural infections of C. parvum may occur in ducks in close contact with humans and other domestic animals and therefore suggests that cryptosporidiosis in ducks may be of public health importance.
The consequences of soil degradation in China: a review
Authors: Delang Claudio O.
Published: January 2019

More than 40% of China’s arable land is degraded. This paper reviews the direct and indirect consequences of soil degradation in China. Soil degradation has observable and measurable impacts, which include soil nutrient loss, salinization, acidification, and desertification. It also has a number of indirect consequences, in particular, a reduction of the agricultural output due to a drop in soil nutrient; an increase in the frequency and magnitude of floods and landslides; a decline in livestock production due to a decrease in grass density available to roaming livestock; an intensification of dust storms and sandstorms which affects health, the productivity of the land, and visibility; and a faster accumulation of silt in dams, which damages their structure, reduces their water storage capacity, and compromises their original functions, in particular their electricity generation capacity.
Unnecessary Medicine, An Issue With Major Ethical Implications
Authors: Ungureanu Gabriel , Alexa Ioana-Dana , Ungureanu Maria-Christina
Published: January 2019

The authors discuss an important chapter of iatrogenic pathology – unneccessary medicine, by reviewing epidemiological aspects and financial impact and identifying such elements in no less than 10 areas: surgery, interventional medicine, diagnostic investigation, substitute procedures, preventive medicine, drug therapy, aesthetic shared medical appointments, surgery, unconventional medicine, medicine on political demand. We shall review the causes, motives and mechanisms of unnecessary medicine such as one’s hyperprudence to cover oneself with diagnosis arguments or to prevent potential complications through preventive therapies (defensive medicine), weak functionality of the institutionalized inspection bodies, onerous motivation. The respect for the fundamental principles of medical ethics (the primum non-nocere principle doubled by the principle of doing good), the use of practice guidelines, the proper functioning self-control mechanisms in exercising the medical profession, a different management of error and the existence of a consistent protective legislation for both the patient and doctor would be key-elements to avoiding unnecessary medicine.

Published: January 2019

Introduction. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown origin, characterized by multisystemic involvement and a potentially severe evolution. Pulmonary arterial hypertension (PAH) is a rare complication of SLE, with low 5-year survival.

Case presentation. We are presenting the case of a female patient, aged 56 years old, diagnosed in 1992 with SLE with cutaneous manifestations (butterfly-shaped erythematous rash), joint manifestations (polyarthritis), serositis manifestations (massive pleuropericarditis), and immunological manifestations (positive anti-dsDNA antibodies, decreased C3), ignored therapeutically for a long time. In 2010 she complained of dyspnea on medium exertion and leg edemas, with marked increase of PAPs by echocardiography. She was diagnosed with severe PAH (confirmed by right heart catheterization) and in the “Marius Nasta” National Institute of Pneumology she started a treatment with an endothelin receptor antagonist (Bosentan) in combination with a prostacyclin receptor agonist (Selexipag). Since 2013 the patient is on oral anticoagulant treatment for permanent atrial fibrillation.

In 2015 she was referred back to out clinic as she complained of recurrent episodes of massive ascites with evacuatory paracenteses in amounts of about 6-9L per paracentesis. After excluding other causes, ascites was considered to be secondary to the SLE, and a treatment was initiated with Hydroxychloroquine (HCQ) and pulse therapy with Methylprednisolone, on which the remission of the ascites was achieved during the following months. Currently, the SLE is well controlled without recurrence of ascites on treatment with HCQ and gradual decrease until stopping of cortisone doses, and the PAH is stable.

Conclusion. PAH is a rare complication of the SLE, with a complex pathophysiological immune mechanism, for which - together with the specific vasodilator treatment - the increase of immune suppression is recommended.

Published: January 2019

Collaborative Clustering is a data mining task the aim of which is to use several clustering algorithms to analyze different aspects of the same data. The aim of collaborative clustering is to reveal the common underlying structure of data spread across multiple data sites by applying clustering techniques. The idea of collaborative clustering is that each collaborator shares some information about the segmentation (structure) of its local data and improve its own clustering with the information provided by the other learners. This paper analyses the impact of the quality and the diversity of the potential learners to the quality of the collaboration for topological collaborative clustering algorithms based on the learning of a Self-Organizing Map (SOM). Experimental analysis on real data-sets showed that the diversity between learners impact the quality of the collaboration. We also showed that some internal indexes of quality are a good estimator of the increase of quality due to the collaboration.

Magnetic field gradient as the most useful signal for detection of flaws using MFL technique
Authors: Usarek Zbigniew , Chmielewski Marek , Piotrowski Leszek
Published: January 2019

The magnetic flux leakage (MFL) technique is extensively used for detection of flaws as well as for evaluation of their dimensions in ferromagnetic materials. However, proper analysis of the MFL signal is hindered by the MFL sensor velocity causing distortions of this signal. Traditionally measured components of the MFL signal are particularly sensitive to the scanning velocity. In this paper, an another signal – the gradient of the normal component of magnetic flux density – was proposed as it is less sensitive to the scanning velocity. Results obtained for scans of the steel plate with artificially manufactured flaws confirm this statement.
Printed detector bands for measurements of strain in core interior of transformers
Authors: Shilyashki Georgi , Pfützner Helmut , Windischhofer Andreas , Trenner Gerald , Giefing Markus
Published: January 2019

In the recent years, the reducing of audible noise of laminated machine cores has become great importance, due to high relevance given to environmental awareness. The strain caused by magnetostriction and magnetostatic forces is recognized as one of the main sources of noise. Especially for transformers, strain in the core interior tends to be different from that on the surface, due to differences of clamping, variation of in-plane fluxes and pronounced off-plane (normal) fluxes. For the first time, local measurements of strain in the core interior are presented by means of a novel printed detector band. First results tend to be very promising, exhibiting very high sensitivity and resolution. So far, the relevance of measurements is restricted to comparisons of different core regions.
Lightness Factors and Exertion Factors Related to its Own Mass of Fiber Reinforced Plastics (FRP) Applied in Composite Aeronautical Structures (Part 1)
Authors: Rodzewicz Mirosław , Lewitowicz Jerzy
Published: January 2019

The paper concerns an application of lightness factors in comparative analysis of strength properties of basic materials being applied in aeronautical structures – in a historical perspective. The use of lightness factors enables effective estimation how lighter will be the structural elements (of the same strength or stiffness) made from different kind of materials : traditional as well as advanced composites. It is quite easy to find the solution to the inverse problem, i.e. to estimate how differ will be stiffness or strength for the same mass of the structural elements. Very particular application of the lightness factors are noted in engineers calculations of composite gliders wing spars, where they appears as the materials constants and as structure loading factors as well. The paper presents some examples of application of the lightness factors in strength analysis of the composite shells applied in the shear webs of the wing spars, and refers to the design recommendations issued by German aviation authority (LBA).
Urban Cycling as an Indicator of Socio-Economic Innovation and Sustainable Transport
Authors: Kwiatkowski Michał Adam
Published: January 2019

Environmental pollution in cities is an increasingly popular issue tackled in research. One of the elements with a significant impact on the state of urban ecosystems is transport with its pressure on individual components of the environment. Sustainable urban transport is gaining prominence as a postulate expressed in cities’ strategic documents, constituting an element alleviating the negative effects of anthropopressure. In the light of the need to introduce innovative solutions for clean forms of transport, numerous papers indicate the bicycle as an answer to some of those problems. The article presents a review of literature referring to the socio-economic aspects of using the bicycle in cities as a means of transport for daily commuting. The analysis is based on publications on cyclist safety in road traffic, the perception of the bicycle as a means of transport in cities, and the introduction of innovative solutions, such as bicycle-sharing systems.
Reclaiming Urban Space: A Study of Community Gardens in Poznań
Authors: Maćkiewicz Barbara , Puente Asuero Raúl , Pawlak Krystyna
Published: January 2019

In this paper, we discuss the presence of community gardens in urban spaces and the types of activities performed there, using the city of Poznań as a case study. First, based on interviews with representatives of selected non-governmental organisations, analyses of available Internet sources as well as our own field research, cartographic and photographic documentation, we identify community gardens in the space of the city and explore their formation process. In the course of our study we also concentrate on the type of garden location. In addition, we devote our attention to the gardens which have disappeared from the fabric of the city. Our study reveals that community gardens currently operating in Poznań are established in non-central locations. These gardens are scattered in various parts of the city. Only in the Łazarz district there are two community gardens. Most frequently, community gardens are established on plots between old blocks of flats and tenement houses. Two gardens are located on underdeveloped greenery near the Warta River and in two city parks. A detailed examination of the events held in the community gardens in the Łazarz district in the years 2014–2017 shows that they had a very diversified character. Both of them turned out to be multifunctional, i.e. hosted meetings devoted to agriculture and horticulture, environmental education, artistic events, DIY and recreation. However, the percentage of events in the structure of the meetings organised in the gardens differed considerably.
Regional Resilience in Ireland and the Existence of a Two-Tier Recovery
Authors: Hennebry Barraí
Published: January 2019

This paper focuses on the increasing regional disparities in Ireland, especially since the great recession and assesses the degree to which the recovery has been concentrated in urban areas. Ireland was initially affected by the recession to a greater extent than other countries but has recovered strongly. However, this recovery has not been evenly distributed, with some regions showing greater economic resilience. Using descriptive statistics of GDP per capita (PPP), GVA and employment, this paper examines the extent to which the recovery has been a two-tier recovery. The paper finds evidence to suggest that the recovery has been heavily concentrated in Dublin, and to a lesser extent in Cork and Galway, resulting in an urban-rural divide.

Authors: Heidari M. , Salmanpour I. , Ghorbani H. , Asghari H.R.
Published: January 2019

In order to investigate the effect of iron chelate and plant growth promoting rhizobacteria (PGPR) on maize, an experiment was conducted as completely randomized block factorial design with three replicates. The first factor included of bacterial strain: S1= Control (without use of bacteria), S2=Azotobacter chroococcum and S3= Azospirillum brasilens and the second factor included of iron chelate: F1= Control, F2= soil application of Fe chelate, F3= foliar application of Fe chelate, F4= soil application of nano Fe chelate and F5= foliar application of nano Fe chelate. The results showed that the highest grain yield and guaiacol peroxidase (GPX) enzymes activity were obtained at the S3F5 treatment and ascorbate peroxidase (APX) at S1F5 treatment. Except the content of phosphorus in leaves and carotenoid, PGPR had significant effect on biological yield, the content of chlorophyll ‘a’ and ‘b’, yield components (number of seed per row of the ear, number of rows per ear and thousand seed weight) and nutrient elements in both the seeds and leaves. However, iron chelate, increased the yield components, but among the iron chelate treatments, the highest amount of chlorophyll ‘a’ and ‘b’ in leaves and phosphorus in seeds were obtained at F5. These results suggested that foliar application of nano Fe chelate and Azospirillum brasilens could be improvement of maize plant productivity.
Chromium in Anthropogenically Polluted and Naturally Enriched Soils: A Review
Authors: Jeřábková J. , Tejnecký V. , Borůvka L. , Drábek O.
Published: January 2019

Chromium (Cr) is a very important element examined for last decades on many expert fields. Its toxicity, mobility and bio-availability are strongly dependent on its oxidation state, Cr(III) and Cr(VI). Hexavalent form Cr(VI) is a known carcinogen with many harmful effects on living organisms, on the other hand trivalent Cr(III) form is an important micronutrient necessary for lipid metabolism. Contamination of the environment by Cr may come from anthropogenic industrial pollution or from naturally enriched sites, especially ultramafic rocks and their derived soils. Environmental conditions of soils and water represent a very complex system, which makes reliable assessment of its fate and potential toxicity and transport a really difficult task. A number of studies have been performed to describe Cr behaviour in these systems, as well as to optimize its determination, especially speciation methods. The main objective of this contribution is to summarize and present the today’s knowledge about the occurrence, speciation, and behaviour of Cr in soil environment, with a specific emphasis to description of differences between naturally enriched and anthropogenically contaminated soils.

Authors: Widyastuti Santiary Putri Alit , Widyantara I Made Oka , Hartati Rukmi Sari
Published: January 2019

This paper proposed Canny edge detection to detected saliency map on traffic sign. The edge detection functions by identifying the bounds from an object on an image. The edge of an image is an area that has a strong intensity of light.The pixel intensity of an image changes from low to high values or otherwise. Detecting the edge of an image significantly will decrease the amount of data and filters insignificant information by not deleting necessary structure from the image. The image used for this paper is a digital capture of a traffic sign with a background. The result of this study shows that Canny edge detection creates saliency map from the traffic sign and separates the road sign from the background. The image result tested by calculating the saliency distance between a tested image and trained image using normalized Euclidean distance. The value ofnormalized Euclidean distance is set between 0 to 2. The testing process is done by calculating the nearest distance between the tested vector features and trained vector features. From the examination as a whole, it can be concluded that road sign detection using saliency map model can be built by Canny edge detection. From the whole system examination, it resulted a accuracy value of 0,65. This value shows that the data was correctly classified by 65%. The precision value has an outcome of 0,64, shows that the exact result of the classification is 64%. The recall value has an outcome of 0,94. This value shows that the success rate of recognizing a data from the whole data is 94%.

Authors: Puffal Daniel Pedro , Da Costa Achyles Barcelos
Published: January 2019

Embora em uma economia de mercado o principal locus onde ocorre inovação são as empresas, a história tem mostrado que, de um modo geral, elas não conseguem se capacitar sozinhas, sendo necessária a existência de um sistema nacional de inovação que as auxilie nessa empreitada. Nesse âmbito, a interação de empresas com universidades e institutos de pesquisas desempenha um papel relevante. O objetivo do artigo é percorrer literatura sobre o tema a partir de periódicos especializados, identificar os indicadores mais utilizados em estudos nessa área e levantar informações sobre a situação brasileira. O método empregado consiste de revisão da literatura e de levantamento de dados da PINTEC. Os resultados do estudo indicam que não há consenso na forma de abordagem do tema, além de haver a existência de uma dispersão nos indicadores utilizados nas análises. Percebe-se que, no Brasil, essa interação ainda é tímida, havendo espaço para avançar nessa direção.Palavras-chave: Inovação. Sistema Nacional de Inovação. Interação universidade-empresa.

No desenvolvimento de uma técnica de visualização, as tarefas que um usuário precisa desempenhar durante sua utilização devem guiar tanto a escolha das metáforas de visualização quanto os recursos de interação implementados pela técnica. Testes de usabilidade de técnicas de visualização também necessitam de uma definição clara das tarefas do usuário. A identificação e o entendimento dessas tarefas é uma questão recente de pesquisa na área de visualização de informações, e alguns trabalhos têm proposto taxonomias para organizá-las. O presente trabalho relata e compara os resultados de estudos de caso conduzidos com o método Multidimensional In-depth Long-term Case studies (MILCs). Os estudos de caso foram executados para classificar as tarefas de visualização em diferentes níveis de abstração, bem como, estabelecer um método de avaliação de usabilidade para ferramentas de visualização baseado no MILCs.Palavras-chave: Visualização de informações. Taxonomia de tarefas. Avaliação de usabilidade.

A moda usada na contemporaneidade busca se reinventar na indumentária e no uso de adornos, desde a Idade dos Metais. Nesse período, tem-se uma grande descoberta na técnica utilizada nos metais, como o cobre, o bronze, o ouro, a prata e o ferro e no estilo artístico das joias . A presente pesquisa mostra a riqueza de detalhes e ensaios artísticos na confecção dos adornos criados para compora indumentária desde o mais longínquo período da Idade dos Metais, o que se pode observar nos alfi netes de metal usados para unir as vestes. O mesmo gosto se estendia a todos os utilitários criados com arte e técnica, legando para a contemporaneidade muitos desses fazeres que acompanham a moda em diferentes épocas, estilos e culturas. Esta pesquisa relata a importância e o fascínio que os metais exerciam sobre o homem, e que ainda inspiram a criação e uso das joias em nossos dias.P a l a v r a s - c h a v e : Moda.

Bu çalışmanın amacı, muhasebe dersi alan lisans öğrencilerinde strese neden olan faktörlerle derse yönelik tutumları arasındaki ilişkinin tespitidir. Araştırmada anket yöntemi kullanılmıştır. Anket, öğrencilerin demografik yapısının belirlenmesi ve strese neden olan faktörler ile muhasebe dersleri ile ilgili tutumlarını tespit etmek için Çankırı Karatekin Üniversitesi İktisadi ve İdari Bilimler Fakültesinde (İİBF) öğrenim gören öğrenciler arasından, kolayda örnekleme yoluyla seçilen 238 öğrenciye uygulanmıştır.  Anket soruları, Frekans Analizi, T Testi ve Tek Yönlü Varyans Analizi teknikleri kullanılarak analiz edilmiştir. Çalışma sonucunda, öğrencilerin başarısız olma korkusu ve mezuniyet sonrası ne yapacağını bilememe kaygısı ve öğrenciler arasındaki gruplaşmanın strese neden olan önemli faktörler olduğu belirlenmiştir. Ayrıca muhasebe derslerinin uygulamaya ve kariyer mesleklerine yönelik olmadığı tespit edilmiştir.
Çimento Sektörü Açısından Sistematik Risk – Finansal Oran İlişkisi: Ana Çimento Üreticisi Ülkeler Karşılaştırması
Authors: UYAR Umut , ÇAĞLAK Emin
Published: January 2019

Halka açık olmayan firmalar için öz kaynak maliyeti hesaplanması, uzun yıllardır finans literatüründe gündemde olan bir konudur. Özellikle organize bir piyasada işlem görmeyen firmalar için sistematik risk değişkeninin hesaplanma zorluğu, konunun odak noktasını oluşturmaktadır. Muhasebe Betası, problemin çözümü için geliştirilmiş bir teknik olmakla birlikte, yapılan çalışmalarda sektörden sektöre, piyasadan piyasaya modellemenin değişiyor olması bu çalışmanın motivasyonunu oluşturmaktadır. Çalışmanın temel amacı, çimento sektöründe farklı ülkelerde faaliyet gösteren halka açık firmaların mali tablo verileri ile sistematik risk göstergesi olan finansal beta katsayıları arasındaki ilişkinin tespit edilmesidir. Bu amaçla, sektörde dünya lideri olan Türkiye ve Diğer Ülkelerde faaliyet gösteren firmaların 2007-2017 yılları arasındaki çeyreklik muhasebe temelli değişkenleri ile hesaplanan finansal beta katsayıları panel veri analizine tabi tutulmuştur. Elde edilen bulgulara göre, aynı sektörde faaliyet gösterseler dahi beta ile ilişkili finansal değişkenler Türkiye ve diğer ülkeler açısından farklılaşabilmektedir. Çalışma sonuçları, teorik beklentilerle açıklanabilmekte ve literatürdeki birçok çalışma ile paralellik arz etmektedir. Aynı sektörün farklı ülke grupları açısından incelenmesi yönünden özgünlük taşımaktadır.
