Published: September 2019

Ilmu pengetahuan dan teknologi terus berkembang dengan pesat, hal ini ditandai dengan pembaruan ilmu-ilmu sains. Kimia Organik merupakan salah satu mata kuliah sains yang kurang disenangi dan dipandang sulit oleh mahasiswa karena bersifat tidak berwujud. Tantangan pembelajaran mata kuliah kimia organik yaitu meningkatkan literasi saintifik mahasiswa. Rendahnya literasi saintifik mahasiswa di Indonesia disebabkan oleh proses belajar mengajar yang masih berorientasi pada penguasaan konsep sains melalui proses presentasi dan diskusi. Tujuan dari penelitian ini yaitu menganalisis respons mahasiswa terhadap penerapan pembelajaran kimia organik dengan cara diskusi dan berargumentasi tentang isu-isu sosiosainstifik untuk meningkatkan literasi sains mahasiswa tadris IPA. Penelitian dilakukan di jurusan Tadris IPA B IAIN Kudus angkatan 2017 yang melibatkan 36 mahasiswa. Metode yang digunakan dalam penelitian ini ialah metode deskriptif. Pendekatan yang digunakan ialah pendekatan kualitatif. Pengambilan data melalui analisis sesuai kebutuhan, observasi dan wawancara. Penelitian ini mengungkapkan bahwa 85% mahasiswa pendidikan IPA setuju bahwa pembelajaran berkonteks isu sosiosainstifik pembelajaran yang menarik. 75% setuju bahwa pembelajaran kimia organik berkonteks isu sosiosainstifik dapat mempermudah pemahaman isi materi. 90% setuju bahwa pembelajaran berkonteks isu sosiosainstifik meningkatkan literasi ilmiah. Pembelajaran mata kuliah kimia organik melalui diskusi dan argumentasi terkait isu-isu sosiosainstifik dapat meningkatkan literasi sainstifik mahasiswa.

Authors: Lin Yulan , Wu Chuancheng , Yan Wei , Guo Saixiong , Liu Baoying
Published: September 2019

Background : Serum trace elements have been some time suggested to influence the development of gastric cancer, but evidence is still lacking.
Methods : In a case-control study from a high risk region of East China, all newly diagnosed patients with gastric cancer were compared with healthy controls 1:1 matched by sex, age (± 3 years) and place of residence during 2013- 2015.
Results : A total of 299cases of gastric cancers, which included 122 cases of gastric cardia cancer (GCC) and 177 gastric non-cardia cancer (NCGC), and 299 healthy controls were included. Positive associations were found between serum copper and copper/zinc ratio and risk of overall gastric cancer (OR 4th vs. 1st quartile : 2.42, 95% CI: 1.10-5.32 for copper, p for trend=0.003; OR 4th vs. 1st quartile : 11.7, 95% CI: 3.83-35.6 for copper/zinc ratio, p for trend<0.0001), and for both GCC and NCGC subtypes. Serum selenium inversely associated with risk of NCGC (OR 4th vs. 1st quartile : 0.18, 95% CI: 0.07-0.51, p for trend=0.0001), while molybdenum seem to reduce risk of GCC (OR 4th vs. 1st quartile : 0.12, 95% CI: 0.03-0.47, p for trend<0.0001). Strong inverse associations were also detected between serum calcium and risk of all groups of gastric cancer (all p for trend<0.05). Although intermediate serum level of zinc and iron had lower risk of gastric cancer, no linear association was however found (all p for trend>0.05).
Conclusions : The current study present evidences for positive associations between copper, copper/zinc ratio and gastric cancer, as well as for inverse associations between serum selenium, molybdenum and calcium and risk of gastric cancer.

Authors: Gebremichael Gebrewahd Bezabh , Zemichael Teklewoini Mariye
Published: September 2019

Background

Hypoglycemia is an acute medical situation that occurs when blood sugar falls below the recommended level. Even though, hypoglycemia prevention practice in the management of diabetes mellitus is one cornerstone in controlling the effect of hypoglycemia, hypoglycemia prevention practice among patients with diabetes mellitus is insufficiently studied. Moreover, the existed scarce literature in Ethiopia revealed hypoglycemia prevention practice is inadequate. Thus, this study tried to assess hypoglycemia prevention practices and associated factors among diabetic patients.Methods

Hospital-based, cross-sectional study design was employed from April one to March one 2018 in Central Zone of Tigray Regional state of Ethiopia. A total of 272 diabetes mellitus patients were selected by systematic random sampling method from study area. The collected data was checked for its completeness and then entered into Epi data version 3.1 then cleaned and analyzed using SPSS version 23. Binary logistic regression model (AOR, 95% CI and p-value < 0.05) was used to determine the predictors of hypoglycemia prevention practice.Results

the mean age of respondents was 52.19 years and about 100 (63.2%) had good hypoglycemia prevention practice. Good knowledge regarding hypoglycemia [AOR = 10.34; 95% CI [5.41, 19.89]], having a glucometer at home [AOR = 3. 02; 95% CI [1.12, 8.12]], favorable attitude towards diabetes mellitus [AOR = 2.36 CI [1.26, 4.39]], and being governmental employee [AOR = 5.19, 95% CI [1.63, 16.58]] were positive predictors of good hypoglycemia prevention practice. However, being divorced [AOR =0.13, 95% CI [0.32, 0.53]] was found negatively associated with good hypoglycemia prevention practice.Conclusion

Around two third of the study participants were found to have good hypoglycemia prevention practice. Good knowledge and favorable attitude toward diabetes mellitus, having glucometer at home, being governmental employee and divorced were found to be the predictors of good hypoglycemia prevention practice.

Published: September 2019

The reverse flow of seawater causes salinity in inland waterways and threatens water resources of the coastal population. In the Pearl River Delta, saltwater intrusion has resulted in a water crisis. In this study, we proposed a tailored approach to chlorinity prediction at complex delta systems like the Pearl River Delta. We identified the delayed predictors prior to optimization based on the maximal information coefficient (MIC) and Pearson's correlation coefficient (r). To achieve an ensemble simulation, a Bayesian model averaging (BMA) method was applied to integrate temporally sensitive empirical model predictions given by random forest (RF), support vector machine (SVM), and Elman neural network (ENN). The results showed that: (a) The ENN performed the worst among the three; (b) The BMA approach outperformed the individual models (i.e., RF, ENN, and SVM) in terms of Nash–Sutcliffe efficiency (NSE), and the percentage of bias (Pbias). The BMA weights reflect the model performance and the correlation of the predictions given by its ensemble models. (c) Our variable selection method resulted in a stronger model with greater interpretability.
Water quality response to river flow regime at three major rivers in Alberta
Authors: Rostami Sajjad , He Jianxun , Hassan Quazi K.
Published: September 2019

Both anthropogenic activities and natural factors affect river water in quantity and quality, while anthropogenic activities have been often blamed to cause water quality temporal degradation. In addition, riverine water quality displays intra-annual/seasonal variations, which are often more prominent than inter-annual variations. The intra-annual variations in water quality, which are attracting the attention of managers and policy-makers, beg the question of how to better manage riverine water quality at a finer time resolution. The natural factors, in particular, the hydro-meteorological variables, could be the primary drivers of the intra-annual variations of riverine water quality. Therefore, this paper examined the association between riverine water quality and one hydro-meteorological variable (flow) with the focus on their relationship at the intra-annual timescale on three selected rivers in Alberta, Canada. The results demonstrated that flow drives intra-annual variation of riverine water quality in general. Moreover, some water quality parameters responded to flow distinctively at three flow regimes (low, medium, and high flows). Water quality parameters were categorized into eight groups according to their responses to flow at the flow regimes. These implied the challenges in water quality management while providing insight into how to formulate more effective water management strategies.

Published: September 2019

The evaluation of irrigation water efficiency plays an important role in the efficient use of agricultural water resources and the sustainable development of agriculture. In order to make the evaluation of irrigation water use efficiency indicators more comprehensive and scientific, this paper constructs a new optimal model of evaluation indicators. By combining the Driver-Pressure-State-Impact-Response (DPSIR) model with the Information Significance Difference (ISD) evaluation indicators model, a novel DPSIR-ISD evaluation indicators combination model was constructed. Ten riverside irrigation areas in the Sanjiang Plain of northeastern China were selected for analysis. The results show that the DPSIR-ISD model was used to reduce the number of indicators from 44 to 14; these 14 indicators reflected 91.88% of the original information. The DPSIR-ISD method proposed in this paper takes into account the completeness and simplicity of the indicators system, and is more in line with the actual situation in the field. These results can provide a simpler and more convenient system for optimizing indicators for the study of evaluation indicators used to analyze irrigation water use efficiency.

Published: September 2019

In this study, a mesoporous TiO2/carbon catalyst (TiO2/C) was prepared by a facile impregnation-carbonization approach to catalyze ozonation of p-chloronitrobenzene (p-CNB). The catalyst was well characterized and the catalytic efficiency under various conditions was systematically evaluated. TiO2/C has a disordered mesostructure with a high specific surface area. 92.8% of p-CNB (2 μmol/L) can be degraded within 20 min in the TiO2/C/O3 system in the presence of 1 mg/L O3, 100 mg/L catalyst, at pH = 5. Based on the evaluation of the effect of basic parameters, it could be deduced that the removal of p-CNB relied on the synthetic effect of catalysis by TiO2/C and the autocatalytic induction of p-CNB. The removal efficiency of p-CNB, the structure change and the leaching of Ti ions were also evaluated in five cycles, indicating TiO2/C is stable and recyclable for catalytic ozonation in water treatment.
Heterotopyalar İçinde Bir Birey Nasıl Yaşayabilir?

Published: September 2019

Michel
Foucault, erken döneminde sosyalist ve varoluşçu düşünceden etkilenerek felsefi
altyapısını oluşturmuş ve yaşamın nasıl bilim olarak incelenebileceğine
odaklanmıştır. Düşünce tarihinde pek yer edinememiş ‘aşk, cinsellik, suç ve
delilik’ gibi konuları filozoftan ziyade adeta bir tarihçi gibi arkeolojik
kazıya benzettiği bir düşünüş yöntemiyle detaycılıkla incelemiştir. Foucault,
kendisinin icat ettiği ‘sorunsallaştırma’ tekniği ile yeni bir iktidar anlayışı
sunmuş, bilgi ve iktidarın çok yakından ilişkili olduğu sonucuna vararak
‘güç/iktidar’ mefhumunu yaratmıştır. Ancak, ortaya koyduğu bu kavramla
iktidarın tanımını yapmaya çalışmamış, zaten onun tanımlanamaz oluşuna dikkat
çekmiştir. İktidarın ne, kim olduğundan çok iktidar etkilerini ve ilişkilerini
sorgulamış; bu ilişkisel ağlar içerisinde kontrol mekanizmalarının nasıl
çalıştığını ve özneleri nasıl nesnelleştirdiğini ortaya koymuştur. Foucault’nun
topos’a sosyal ve kültürel farklı boyutlar katarak özne ve iktidar kuramlarıyla
ilintili geliştirdiği ve ‘gerçekleşen ütopya’ şeklinde tanımladığı
‘Heterotopya’ ise, toplumun kurumsallaşmasında yer alan ötekiliğin gerçek
mekanları/uzamlarıdır. Heterotopyalar, öznelerle ve diğer mekanlarla kurdukları
ilişkilerle çok fazla çeşitlenirler, dolayısıyla öznelerin nesneleştirilmesiyle
alakalı tüm politik, dini, kültürel söylemlerin yaratabileceği ve dönemsel
koşullara bağlı da türlerinden bazılarının yok olabileceği ya da yenilerinin
eklenebileceği yerler, mekanlar, uzamlardır. ‘Bir birey nasıl yaşayabilir?’
sorusu ekseninde geliştirilen bu çalışmada, Foucault’nun heterotopyayla ilgili
tek kapsamlı açıklama yaptığı ‘Of Other Spaces: Utopias and Heterotopias’ adlı makalesi baz alınarak
heterotopyanın kuramsal çerçevesi tanıtılacak, heterotopya türleri incelenecek

Published: September 2019

Rasashastra is a special branch of Ayurveda where in different Herbs, Mineral and Metals are used in various formulations.These metals and minerals are subjected for different purification methods to make it suitable for internal administration. The Marana is the procedure in which the purified metals or minerals are further triturated with specific drugs and subjected to heat (Puta). For various Herbs, Metals and Minerals the applications of Puta is essential to reduce the particle size for its better absorption in the body. Swayamagni Rasa is the herbo-mineral preparation were in, self generated heat transforms the particle size from Loha Churna into Bhasma form. In this study Iron fillings where used to prepare the Bhasma by subjecting it to Samanya and Vishesha Shodana and later on doing the procedure of Marana according to Rasachintamani. During the process of Shodana care has to be taken while heating the iron fillings throughout the procedure and measured quantity of liquid media for quenching has to be maintained for doing Shodana in bulk. During the process Iron fillings tend to flush over the face during each Nirvapa which has to be dealt with precaution. Thereafter analysis of the Swayamagni Rasa was analysed using SEM-EDX. It was observed that the percentage of Oxygen content in Loha Bhasma increased there by stating it to be in Oxide form and The particle size ranges around 173.3 nanometre scale which proves it being in its minutest form.

Published: September 2019

Therapeutic actions of medicinal plants are due to the chemical components present in them. These chemical constituents often vary with change in geographical and climatic conditions. Climate, altitude, and temperature play an important role to make a herb therapeutically potent. Ancient Ayurvedic physicians mentioned that medicinal plants which grow in Himalayan region are more potent as compared to the plants growing in other regions. A modest study was therefore undertaken to compare the in vitro anticancer activity of Plumbago zeylanica Linn. collected from Himalayan region and Western Ghats with respect to their chemo profile and genetic patterns. Variation in physio-chemical, phyto-chemical, the genetic profiles were observed in plants collected from these two regions and corresponding variation was also seen in their anticancer activities.

Syntactics, Cognition and Compositional Semantics
Authors: Norman Boris Ju.
Published: September 2019

The object of the article is word semantics and its realization in the immediate context. The goal and the innovative component of the study is the analysis of the problem in the light of cognitive linguistics. We proceed from the assumption that the lexical meaning of a word contains a component responsible for its entry into the text. This component involves searching for lexical partners of the word in the syntagmatic chain. The semes participating in this process are actualized - they must get into the bright field of con-sciousness. The classical manifestation of this connection is the soalled semantic agreement ( собака лает ‘a dog barks’, бурый медведь ‘a brown bear’, волосы дыбом ‘hair (stands) on end’, etc.). We use examples from Russian literature to demonstrate that when a non-typical (non-standard) word combination is formed, the concepts get intersected (mixed). The examples, such as самопишущий костюм ‘a self-writing suit’ or жаркая робость ‘hot timidity’, expand a person’s cognitive horizons making the individual accustomed to a different (virtual) reality. The background and guarantor of this combinatorial process is the so-called “common sense” based on the native speaker’s previous experience. The result of the study is the presentation of five special situations manifesting the relationship between the word and its text partners: polysemantic words, phraseological units, introduced (embedded) meanings, additional connotations and a surprise effect. The author provides examples of the pressure (influence) of text memory on the speaker when selecting a necessary word and considers the idea of the predicative nature of the compatibility of lexemes. The article justifies the emergence of compositional semantics as a special direction in modern linguistics and demonstrates some of its results (based on the Russian language).

Authors: Supar Norizah
Published: September 2019

The objective of this study is to expand our understanding of the factors that affect knowledge sharing among academic staff in Malaysian higher academic institutions. Although previous research has identified several factors that affect knowledge sharing, further research needs to be carried out to ascertain factors that affect knowledge sharing, in particular among higher academic institutions in Malaysia. Its relevance to higher academic institutions is especially pertinent considering that being a center of learning, a higher level of knowledge sharing among the teaching staff could bring about an increased level of productivity or performance and satisfaction in the workplace. The outcome of this study will enable further understanding on knowledge sharing behavior of academic staff and may therefore contribute towards successful implementation of knowledge sharing as part of organizational knowledge management initiatives. Based on non-random, criterion, purposive sampling, three higher academic institutions from the Klang Valley area were selected to be included in the study. Findings from 194 respondents indicated that the technological factors of distributed model and presence of IT for knowledge sharing are positively related to knowledge sharing and that knowledge sharing is positively related to performance.
An Experimental Study of the Genetic Algorithm Convergence
Authors: Elhaddad Younis
Published: September 2019

Genetic algorithm is a well-known heuristic search algorithm, typically used to generate valuable solutions to optimization and search problems. The most important operation in a genetic algorithm is crossover, as it has the greatest effect on its convergence rate. Therefore, in order to achieve the most optimal results in a reasonable time, one has to decide on the crossover type, as well as make a selection of a crossover point. In order to explore the effect of the crossover point selection methods on the convergence rate, we conducted experiments based on different crossover point selection criteria, whereby the results indicate the high importance of controlling the randomization of the crossover point selection range.

Published: September 2019

OBJECTIVE

To better understand potential facilitators of individual engagement in type 1 diabetes natural history and prevention studies through analysis of enrollment data in the TrialNet Pathway to Prevention (PTP) study.

RESEARCH DESIGN AND METHODS

We used multivariable logistic regression models to examine continued engagement of eligible participants at two time points: 1) the return visit after screening to confirm an initial autoantibody-positive (Ab+) test result and 2) the initial oral glucose tolerance test (OGTT) for enrollment into the monitoring protocol.

RESULTS

Of 5,387 subjects who screened positive for a single autoantibody (Ab), 4,204 (78%) returned for confirmatory Ab testing. Younger age was associated with increased odds of returning for Ab confirmation (age <12 years vs. >18 years: odds ratio [OR] 2.12, P < 0.0001). Racial and ethnic minorities were less likely to return for confirmation, particularly nonwhite non-Hispanic (OR 0.50, P < 0.0001) and Hispanic (OR 0.69, P = 0.0001) relative to non-Hispanic white subjects. Of 8,234 subjects, 5,442 (66%) were identified as eligible to be enrolled in PTP OGTT monitoring. Here, younger age and identification as multiple Ab+ were associated with increased odds of returning for OGTT monitoring (age <12 years vs. >18 years: OR 1.43, P < 0.0001; multiple Ab+: OR 1.36, P < 0.0001). Parents were less likely to enroll into monitoring than other relatives (OR 0.78, P = 0.004). Site-specific factors, including site volume and U.S. site versus international site, were also associated with differences in rates of return for Ab+ confirmation and enrollment into monitoring.

CONCLUSIONS

These data confirm clear differences between successfully enrolled populations and those lost to follow-up, which can serve to identify strategies to increase ongoing participation.

Abstract

In the thirties, an expressive movement of Brazilian educators discussed and proposed new pedagogic ideas in opposition of to traditional practices and concepts prevalent in schools in that period. This movement was called Escola Nova. This article aims to review some principles of Escola Nova in order to indicate some aspects of rupture and continuity of that movement that can be met in the educational reform of the nineties, in Brazil. It focuses upon four dimensions: the socialization function of the school, centrality of individual and the learning process, the school as a mechanism of equalisation of social inequalities and the school as the place of learning the democracy.

Keywords: educational change; educational policy; school.

Published: September 2019

The objective of the current study is to evaluate the complication rates (embolic and hemorrhagic events) in deep venous thrombosis (DVT) patients on different types of oral anticoagulation therapy (OAC): direct oral anticoagulant therapy and vitamin K antagonist therapy.

Methods: A number of 62 DVT patients were included and divided in two groups, depending on the type of oral anticoagulation therapy administered. The first group was composed of patients treated with direct oral anticoagulant treatment (Dabigatran, Rivaroxaban) and the second group was composed of patients treated with vitamin K antagonist (Acenocumarol). General data, including BMI and comorbidities were noted. Embolic and hemorrhagic events were noticed.

Results: in the first group of patients (DOAC therapy), a number of 34 patients were included (14 of them with BMI higher than 25 kg/m2 and 14 with concomitant atrial fibrillation), while the second group comprised of 28 patients treated with VKA (21 of them with a high BMI and only 3 of them with atrial fibrillation). After a mean period of 36 months of anticoagulant therapy, complications were present in 17 patients, hematuria (8 episodes) and pulmonary embolism (4 cases) were the most frequent, with no difference regarding the treatment applied.

Conclusion: No statistically significant difference was encountered regarding embolic and hemorrhagic event rates in our deep vein thrombosis patients.
MicroRNAs as Biomarkers and Therapeutic Targets in Heart Failure
Authors: Szabó István Adorján , Frigy Atilla
Published: September 2019

Heart failure still represents a real challenge both in everyday practice and research, due to the complex issues related to its pathogenesis and management. Humoral biomarkers have emerged in the last decades as useful tools in the diagnosis, risk stratification and guiding the treatment of heart failure. These molecules are related to different pathological and adaptive processes, like myocardial injury, neurohormonal activation and cardiac remodeling, their most widespread representatives being the natriuretic peptides (e.g. NT-proBNP). The role of altered gene expression and transcription as the basis of myocardial structural and functional changes in heart failure is largely recognized. MicroRNAs (miRNAs) are non-coding RNAs which have a major role in post-transcriptional gene expression by interfering with messenger RNA molecules. Our short review summarizes the molecular biology of miRNAs and their possible role as biomarkers in the diagnosis and prognosis of heart failure. Furthermore, the therapeutical perspectives conferred by these molecules are also presented.

Published: September 2019

Introduction: Hypertension is one of the most important modifiable risk factor related to cognitive decline and dementia. However, screening for cognitive dysfunction is not part of the routine clinical assessment.

Case presentation: In this report, we present the case of a 75 year old hypertensive male patient with new-onset atrial fibrillation, admitted to the Cardiovascular Rehabilitation Clinic Târgu Mureș. Apart from the routine clinical assessment, the evaluation of cognitive functions was performed with three different screening instruments which identified cognitive dysfunction. Depressive state was assessed with the shortened 13 items form of the Beck Depression Inventory BDI-13 (BDI-13) and it showed moderate depression which could influence the results of cognitive tests. Detection of cognitive impairment was followed by magnetic resonance imaging, which revealed not only hypertension specific microvascular impairment but also a sequelae of a former stroke in the territory of the left middle cerebral artery and a possible meningioma.

Conclusion: Screening for cognitive dysfunction in high-risk hypertensive patients can be easily performed and in several cases like ours, can unmask silent cerebrovascular pathologies, leading to prognostic and therapeutic consequences.

Authors: Benguerai Abdelkader , Benabdeli Khéloufi , Harizia Abdelkader
Published: September 2019

Algeria loses more than 20,000 hectares of forest to fire every year. The losses are costly both in terms of life and property damage, which weighs heavily on the environment and the local economy. Geomatics can complement the conventional methods used in fire hazard prevention and management. The objective of our study is to use the geographic information system (GIS) and the Remote Sensing (RS) technology to develop the fire risk assessment map of the forest massif of Zelamta located in Southeast Mascara province (Northwest Algeria). The methodology employed was an empirical model involving three parameters that can control fire behaviour: geomorphology, vegetal cover combustibility, and human activity. The obtained results can help in the decision-making process as well as provide cartographic support for forest fire prevention and management.

Published: September 2019

In this paper, for the orthogonal group G = O(2) and special orthogonal group G = O
+(2) global G-invariants of plane paths and plane curves in two-dimensional Euclidean space E
2 are studied. Using complex numbers, a method to detect G-equivalences of plane paths in terms of the global G-invariants of a plane path is presented. General evident form of a plane path with the given G-invariants are obtained. For given two plane paths x(t) and y(t) with the common G-invariants, evident forms of all transformations g ∈ G, carrying x(t) to y(t), are obtained. Similar results have obtained for plane curves.

Published: September 2019

The concept of generalized exponential trichotomy for linear time-varying systems is investigated in relationship with the classical notion of uniform exponential trichotomy. Some key properties of generalized exponential trichotomy are explored through supplementary projections. These results are also extended to the case of projection sequences, while certain applications for adjoint systems are suggested.
Measuring the Significance of Writing Style for Recommending Where to Publish – A Case Study
Authors: Karnalim Oscar , Qashri Aulia Zahrina
Published: September 2019

Writing style plays a role in publication venue recommendation. However, such finding should be observed further; it is concluded from an arbitrary dataset which contains various topics and writing quality. This paper aims to observe that style's impact in a more controlled environment. A dataset with the same specific topic and writing quality was used and analysed. In our case, the dataset is comprised of papers published on reputable software engineering publication venues with natural language generation as the specific topic. According to our observation, writing style only affects significantly on paper title wherein the impact is proportional to n in n-gram. Moreover, the style’s impact becomes more salient when the venues are grouped per publisher or only a specific publication type is considered.

Published: September 2019

In this paper, we present the design of a compact laser system for animation projections both indoors and outdoors. Our focus is on the hardware and software aspects of the electronic control of the system from the design phase to the experimental tests and evaluations. The main purpose behind our development efforts is the creation of an affordable laser system for research, entertainment and marketing purposes using contemporary advances in electronics, software development, semiconductor laser diodes and optics. The system is “smart” in the sense that it connects to other devices and the Internet via a WiFi network, so that in addition to doing standalone laser projections, it also has remote control and remote debugging capabilities. Via its two embedded microcontrollers, the system offers an easy integration into existing Internet of Things (IoT) infrastructure. The experimental results are very promising and bring us closer to creating a viable product from both a technological and an economic standpoint.

Authors: Stevanović Suzana , Gavrilović Zvjezdana
Published: September 2019

CRM (Consumer Relationship Management) is a recent concept. Development and introduction of this concept in the banking operations started in the ‘90s. Due to complex market conditions and the current environment in which banks operate, it is necessary to have a new method for doing business, which will provide quick and efficient recognition of clients. This business concept entirely replaces the traditional operating methods of the bank, where the focus is on clients, their needs, and wishes. The CRM concept enables the bank to respond to the individualized demands of the clients with quality banking products and services. With this, the banks manage to deal with the tough competition and make a profit. The goal of this paper is to examine the importance, development, and implementation of the CRM in the banks. The paper tries to prove the hypothesis: Introduction of the CRM philosophy in the banking operations leads to increased profitability of the bank.
