Authors: Suadi Suadi , Soeparno Soeparno , Widianingroem Retno
Published: October 2019

Small-scale marine capture fisheries have contributes to community welfare at Yogyakarta’s south coast. Government has planned some programs to develop fisheries. The development supposed only at rational effort in which fishers still gain advantages. Precautionary approach using bio-economic model of Gordon-Schaefer was applied to analyze the issue. The linear regression model of catch per unit of effort (C/f) (CPUE) and effort (f) was C/f = 59,851 – 0,0005f (R2 = 82, 71%). Fish price assumed at Rp 7,735.19 /kg with operational cost of Rp 59,835.67/trip. Total revenue and effort at maximum sustainable yield was predicted at Rp 13,396 billion and 56,860 trip (equals to 327 vessels), respectively. Fisher income at this level was Rp 167,774.51/trip/vessel. Fish exploration level in this area has already closed to total allowable catch. Free access equilibrium in which cost is equal to revenue might reach at effort of 102,231 trip (equals to 568 vessels). Managing fisheries at maximum economic yield might rise fisher income 17.83% comparing to maximum sustainable yield, but total revenue decreased 1.77% at 56.13% of existing effort. Some management strategies should be promoted and regulated for the fishery exploitation. Based on the results, those possible strategy were 1) limiting investment through regulation and permission; 2) improvement of fishers productivity through technology improvement to exploit  under-used fish resources; 3) expanding the fisheries activity to offshore through harbor development and social preparation; 4) marketing improvement through revitalization of fish action; 5) improving hadling and post harvest fish technology through training and extension; 6) the increasing of bargaining position through empowering fishers group; 7) promoting alternate incomes through integrated coastal tourism development; and 8) avoiding competition and conflict through developing Java’s south coast cooperation. Participatory approach in planning, developing and evaluating should be promoted to develop fishery a southern coast of Yogyakarta.

At What Age Should Information on Genetic Testing be Accessible in Order to Raise Awareness and Prevent Genetic Disease among the General Population?
Authors: Gabaren Sara
Published: October 2019

Hereditary genetic diseases are illness that may be early identified, and there is agreement of the World Health Organization on the tests’ importance and its effectiveness. However, the screening test’ performance, as it is currently carried out, is affected by lack of information, which its damages range between lack of general knowledge on screening test’ performance to a situation in which the screening test are performed in the absence of informed consent. Therefore, there is a need to promote knowledge about the actual exams performance and their significance among general population. The question is what is the right age and manner to make this knowledge available in order to obtain a reasonable level of knowledge sufficient for informed consent. As of today there is not much literature dealing with this question and there is no consensus concerning the way of making the information available. Therefore, there is a need in additional research and extensive public debate concerning the promotion of knowledge about screening test, even only to provide informed consent in situations where the exam performance is mandatory and unavoidable.

Authors: Daflon De Faria Walace
Published: October 2019

A intubação submentoniana ou também conhecida como submento-oro-traqueal é uma técnica que conquistou diversos cirurgiões maxilofaciais ao longo dos anos, que por sua vez realizaram algumas pequenas alterações de acordo com seus conhecimentos anatômicos e vivência profissional. É um procedimento considerado seguro, fácil, rápido e de baixa morbidade. Por esse motivo é utilizada como alternativa para a traqueostomia, largamente utilizada e que possui maiores chances de complicações pós-operatórias. A intubação esta indicada para cirurgias de traumas panfaciais, em que há necessidade de manusear a oclusão do paciente no transoperatório, bem como em situações em que as técnicas consideradas mais convencionais, intubação orotraqueal e nasotraqueal, são contraindicadas. Além disso, atualmente pode ser indicada para cirurgia ortognática bimaxilar com rinoplastia simultânea, rinoplastia isolada e uma alternativa viável para pacientes portadores de fissura labial e/ou palatina. O objetivo deste trabalho é discutir as indicações e contraindicações deste método de intubação através de uma revisão de literatura, além de descrever os passos para sua execução. Palavras-Chaves: Trauma Maxilofacial; Intubação; Submento-Oro-TraquealABSTRACT The submental intubation or also known as submento-oro-traqueal is a technique that has conquered several maxillofacial surgeons over the years, in turn performed some small instances according to their anatomical knowledge and professional experience. It is a procedure considered safe, easy, fast and of low morbidity. For this reason it is used as an alternative to the widely used tracheostomy and has a higher chance of postoperative complications. Intubation is indicated for panacea trauma surgeries, in which there is a need to handle the occlusion of the patient in the intraoperative period, as well as in situations in which the techniques considered more conventional, orotracheal and nasotracheal intubation are contraindicated. In addition, it may currently be indicated for bimaxillary orthognathic surgery with simultaneous rhinoplasty, rhinoplasty alone and a viable alternative for patients with cleft lip and / or palate. The objective of this study is to discuss the indications and contraindications of this method of intubation through a literature review, in addition to describing the steps for its execution.  Key words: Maxillofacial Trauma; Intubation; Submento-Oro-Tracheal.

Published: October 2019

Esta entrevista é parte de uma série de conversas que compõem um mosaico de diferentes vozes, visões, perspectivas do que seria essa relação de uma escola de arte do século XXI a partir desse binário “Escola / Floresta”. Esse binário é uma reverência, certamente, a todas as fricções que Oswald de Andrade coloca no Manifesto Antropofágico. Keyna Eleison representa uma das importantes fronteiras de resgates antropofágicos da arte contemporânea. Nos últimos anos, sua atuação vem assumindo a convergência de resgates transculturais, de ancestralidades afro-brasileiras que não se enquadraram ou foram reprimidas pela razão europeia. Nesta entrevista, Keyna Eleison fala dessa virada para a produção de conhecimento que não venha pelos cânones e padrões dessa mesma razão esteticista visual. Aqui tem-se um pouco do reconhecimento do poder da voz, da linguística como cognição de presenças ancestrais.

Authors: Hou Bo , Mutuc Eugene Burgos , Wu Linhai , Lee Hsiu-Yu , Lu Kun-Hwa
Published: October 2019

This study assesses the sustainability of rice farming through the perspectives of farmer attributes and land ecosystem – sub-categorized as the socio-economic profile of farmers, resources, constraints, investments, and its economic contribution to the economic pursuits of families of farmers. It also proposes a program which can improve rice production in Bulacan, Philippines, and similar contexts. This study discusses the identified rice farming constraints such as inadequate capital, high cost of labor, inadequate supply of farm inputs, poor marketing outlet, high cost of pesticides, high cost of fertilizer, issues on land tenure system, ignorance on the existing rice farming programs of the government, poor storage facilities, high cost of transportation, pests and diseases, and climate change. The contributions of rice farming to the economic pursuits of families of farmers are analyzed in terms of their gross profit, savings, and family living expenditures such as food, clothing, recreation, personal item, health care, education, utilities, transportation, dwelling maintenance, and appliances/furniture. Lastly, the suggestions for sustainable and human health facilitating rice farming in developing countries are discussed.

Authors: Vitas Jasmina , Vukmanovic Stefan , Cakarevic Jelena , Popovic Ljiljana , Malbasa Radomir
Published: October 2019

Bioactive properties, as well as chemical composition and sensory characteristics of traditional and alternative kombucha broths were examined. Samples were produced by adding 10% of kombucha starter to sweetened (7% sucrose) decocts of black and green teas (traditional substrates) and infusions of winter savory (Satureja montana), peppermint (Mentha?piperita), stinging nettle (Urtica dioica), wild thyme (Thymus serpyllum), elderberry (Sambucus nigra) and quince (Cydonia oblonga), at 25?C. Fermentation lasted the shortest with elderberry (3 days) and the longest with quince (10 days). The samples with black tea and peppermint had the best sensory quality. In general, alternative products had better antioxidant activity to hydroxyl radicals than the traditional ones, reducing power and angiotensin-converting enzyme inhibitory activity. The most pronounced acetic acid content was obtained with elderberry substrate. Moreover, peppermint substrate showed the highest values both for total phenols and total flavonoids contents. Taken together, the samples produced with the alternative substrates highlighted a higher phenolic and flavonoid contents, compared to the ones obtained with the traditional substrates.
Harmonicity and differential equation of involute of a curve in E3
Authors: Cakir Osman , Senyurt Suleyman
Published: October 2019

In this paper, we first give necessary conditions in which we can decide whether a given curve is biharmonic or 1-type harmonic and differential equations characterizing the regular curves. Then we research the Frenet formulas of involute of a unit speed curve by making use of the relations between the involute of a curve and the curve itself. In addition we apply these formulas to define the essential conditions by which one can determine whether the involute of a unit speed curve is biharmonic or 1-type harmonic and then we write differential equations characterizing the involute curve by means of Frenet apparatus of the unit speed curve. Finally we examined the helix as an example to illustrate how the given theorems work.
Self-equilibrated stresses in the system composed of a covering layer + spatially locally curved reinforcing layer + half-space
Authors: Tekercioglu Ramazan
Published: October 2019

The system composed of a face covering layer + spatially locally curved substrate reinforcing layer + half-space is taken into consideration. It is presumed that this framework is compressed at infinity by uniformly distributed normal forces and it is required to establish the self-equilibrated normal stresses in that, caused by locally curved of the substrate reinforcing layer. The matching boundary and contact value problem is defined within the scope of 3-D geometrically non-linear exact equations. Formulated problem?s solution is introduced with the series form of small parameter which represents the degree of the aforesaid locally curving. These series? zeroth and first approximation are ascertained with the utilization of double Fourier transform. The original of values that are searching is ascertained numerically. Corresponding numerical outcomes about the self-equilibrated normal stress caused by this spatially local curving are presented and discussed.

The present work considers Marcus-Wyse topological approach which was established for studying 2-D digital spaces, ?2. We introduce the digital singular homology groups of MA-spaces (M-topological space with an M-adjacency), and we compute singular homology groups of some certain MA-spaces, we give a formula for singular homology groups of 2-D simple closed MA-curves, and an algorithm for determining homology groups of an arbitrary MA-space.
Shareholder Litigation and the Information Content of Management Voluntary Disclosure
Authors: Ma Yuanyuan
Published: October 2019

I study the information content of management voluntary disclosures disciplined by shareholder litigation. I model the litigation mechanism in which legal liabilities are based on the damages that shareholders suffer from buying a stock at an inflated price. I find that management does not fully reveal private information in equilibrium. Instead, their disclosures reveal only a range in which their private information lies. Thus, the precision of information is, to some extent, lost. Notably, increasing the severity of legal liability does not always reduce the loss of precision. In fact, when the legal liability reaches a certain level, more severe legal liability will result in less precise disclosures. I also find that good news and bad news have different precision. Specifically, good news is more precise than is bad news when legal liabilities are high, and bad news is more precise than is good news when legal liabilities are low.
Big 4 Alumni's Attitudes and Behavior Toward their Former Firm
Authors: Cannon Nathan H. , Herda David N. , Puffer Thomas M.
Published: October 2019

This article summarizes a recently published academic study (Cannon, Herda, and Puffer 2019) that examines factors associated with Big 4 alumni's proclivity to benefit their former firm by recommending the firm to others as a potential service provider or employer (i.e., post-employment citizenship). Based on social exchange theory, our study predicts and finds that alumni who perceive their firm treated them fairly and supported them during their time with the firm are more committed to the firm, and therefore more likely to engage in post-employment citizenship. Although we find that firm commitment decreases after individuals exit the firm, our results suggest that the firm's alumni outreach efforts (both formal and informal) can help soften this decline. Practical implications for audit firms are discussed.
Bank Audit Fee Pressure During the Financial Crisis
Authors: Porter Christine M.
Published: October 2019

This study examines the pressure on bank audit fees during the height of the financial crisis. I employ a prior year benchmark audit fee method and compare it to the actual audit fee to determine the amount of fee pressure applied in a year. Results show a significant amount of fee pressure exerted upon bank auditors during 2008, more so than that found in studies of other industries. This study also investigates a bank specific fee model during the crisis finding differences in determinants of fees for those banks that did apply fee pressure.

Clinging to Excel as a Security Blanket: Investigating Accountants' Resistance to Emerging Data Analytics Technology
Authors: Schmidt Pamela J. , Church Kimberly Swanson , Riley Jennifer
Published: October 2019

While many business publications stress the importance of data analytics skills and technology, The Wall Street Journal reports strong reactions of accountants faced with a move away from Excel. Accountants are traditionally the reliable source for business information, but that position may be eroded by the emerging profession of data analysts. Looking to the future, Big Four accounting firms stress the need for data analysis skills, and universities are launching degree programs. But what is the reaction of current working professionals? Are they heeding the call for data analytics? Evidence indicates there is some resistance to adoption of data analytics practices. This research proposes the use of Status Quo Bias Theory to investigate the reactions of accounting professionals across the spectrum of accounting sub-disciplines. The study seeks to understand factors that may influence practicing accountants' resistance to adopting new data analysis technologies.

Published: October 2019

Recently, accounting academics have reported increased attention in the accounting profession toward the employment of various technologies. These studies only highlight the exploitation of these technologies in the profession and areas for future research, while missing the need for modernizing the accounting curriculum to meet the industry's technological needs. This paper follows an integrated model for curriculum redesign to reflect blockchain technology, business data analytics, and artificial intelligence employment in the accounting profession. By building on the main four educational curricula designs components, we propose ways to incorporate these technologies into the accounting curriculum. Current industry implementation of new technologies should be considered by academia when designing accounting curriculum to prepare graduates for the market and to ensure their employability. This paper calls for radical changes in the accounting curriculum to reach a balance between existing accounting knowledge and information technology skills relevant to the profession.

Authors: Doroshkevych Dariia , Ilyash Olha
Published: October 2019

The modern banking sector shows growing competition. In order to stay
afloat, it is necessary to use new methods that increase the level of customer
centricity and help to retain old customers and attract new ones.

In the presented paper, the problem of qualitative and fast customer
service of the commercial bank UKRSIBBANK, which can be achieved through
optimization of business processes of servicing customers (private
individuals), is considered. The main tool is the Business Process
Reengineering method, which involves the automation of cash operations, namely:
providing banking services with the help of cash terminals. The essence of the
improvement is to carry out transactions using special cash terminals, which
can replace the cashier and bank teller positions in a bank.

As a result of the business processes reengineering,
the main tasks set at the beginning of the paper were solved. Those were cuts
in staff involved in cash management business processes and a reduction in
customers’ time for performing simple cash operations, which have been shown
using specific business processes in the presented paper.

In addition, BPR influenced the following criteria:transactions between
clients' accounts, transactions between different banks' accounts, the level of
quality of financial monitoring, quantity of paper documents that confirm
transactions, quantity of cash operations that are done by cashiers, the level
of control of business-processes, time of cash operations, the level of staff
turnover, a reduction of quantity of cashier staff, the level of client
orientation, the level of time waiting in lines, quality of clients' service,
quantity of clients that are satisfied with service, quantity of clients that
are ready to recommend the bank to others.

Moreover, the impact of reengineering on the organizational structure and
document circulation of the bank is considered in the work.

INCREASING QUALITY OF CLASSIFYING OBJECTS USING NEW METRICS OF CLUSTERING
Authors: Azhmukhamedov Iscandar Maratovich , Demina Raisa Yurevna
Published: October 2019

The article touches upon one of the main problems of machine learning - clustering objects. It has been widely used in various subject areas: marketing, sociology, psychology, etc. Clusterization algorithms, as a rule, are based on a metric that reflects the distance between objects. However, in some cases it is not practical to use the distance between objects. In certain situations, it is possible to say that one object is similar to the other, the latter being not similar to the former. The original picture and its copy may serve as an example. For such cases, a measure of object similarity is proposed in the work, which shows how many features of one object are contained in another one. A similarity matrix is built on this measure, the analysis of which allows revealing clusters of mutually similar objects. When testing the proposed clustering method, the Rand index (the proportion of correctly connected or unrelated objects) made 0.93. There has been proposed an algorithm that allows to form a set of objects absolutely different from each other. A set of objects formed in this way can later become a learning set for classifiers and increase their fidelity in recognition.

Travels and Social Space of Europe in Reflection of Intellectuals on the Interwar Period
Authors:   Ural Federal University, Satybaldina Diana Kairatovna
Published: October 2019

The travel notes and travel memories as a source of analysis of the social space of Europe during the interwar period are discussed in the article. These literary and journalistic works allow to assess dynamically the socio-cultural situation that has developed in this period. Based on the works of famous intellectuals, who are representatives of different European regions of this period, – S. Zweig, K. Chapek, A. Vertinsky and S.E. Trubetzkoy, the dichotomous nature of social space of Europe in 1918–1939 years is demonstrated. On the one hand, it contains a desire to overcome the tragic existential experience and destructions of the First World War, and on the other hand – the inability to exclude memories and practices, for example, using various forms of leisure, one of which were travels.
MANAGING TECHNOLOGY IN MACEDONIAN SMEs CONTEXT: PERCEPTIONS, PRACTICES AND CHALLENGES
Authors: HRISTOVA Snezhana , STEVCESKA-SRBINOVSKA Dusica
Published: October 2019

Academicians and policy makers alike state that technology is the catalyst of growth for small medium businesses (SMEs). The review of past research reveals that the strategic upside of technology is the accomplishment of competitive advantage through their business strategies. The effective implementation of advanced technologies enables companies to achieve economies of scale and scope simultaneously. That is, investigating advanced technologies reduces the cost of future product innovation, allowing the company to increase its speed of response to market and competitive changes. Therefore, investment in advanced manufacturing technologies represents a strategic option. Despite the great importance of technology in small sized businesses, not many studies attempted to explore technology embraced by them, especially within the Macedonian context. The purpose of this paper is to gain an understanding of advanced technology knowledge and usage within the specific SME sector in the Republic of North Macedonia and to discover, if technology is used, whether it is seen as crucial to their competitive strategy. Moreover, the main research question is how advanced technology affects different aspects such as costs, sales and profitability, employee productivity, customer care, share of the e-market and competitiveness. Primary data were obtained through a questionnaire survey, carried out in small and medium sized businesses in the Republic of North Macedonia and evaluated using the tools of descriptive statistics and the methods of comparison, induction, deduction and synthesis. The research results indicate that advanced technology influences favorably the overall costs and also increases profitability. Likewise, the findings show that advanced technology leads to increase of productivity and sales. One of the conclusions of the paper is that small businesses find it important to invest in advanced technology in order to promote competitiveness.

Published: October 2019

It is a fact that consumer behaviour changes according to the decisive events that occur in people's lives. More precisely, they buy different products or services when events such as marriage, childbirth or the loss of a family member occur. Music, on the other hand, is a service product which use does not change depending on what events occur in people's lives. In fact, there are songs that are required at weddings, christenings and funerals. This article examines first of all (a) what defines the songs of Imagine Dragons and Lady Gaga, more specifically (1) the source of their emotions in their songs, (2) what these songs provide beyond emotions and how these things materialize, (3) what they convey to society, as well as (b) how marketing mix elements are represented in the music industry.

Reflections on CABANA Trial (Catheter Ablation versus Antiarrhythmic Drug Therapy for Atrial Fibrillation Trial)
Authors: Medeiros de Vasconcelos José Tarcísio
Published: October 2019

Atrial fibrillation has been consolidated in recent decades as a serious public health problem, considering its notorious increase in prevalence with aging combined with increased population survival. Data from the Framingham Heart Study indicate that, even in an optimal scenario of absence of classic risk factors for its occurrences, such as smoking, alcohol abuse, obesity, hypertension, diabetes, and heart disease, about 10% of individuals aged 80 or over and about 25% of those aged 90 or over will have atrial fibrillation. These rates substantially increase when added to single or combined risk factors. Despite its already well-known association with the occurrence of thromboembolic stroke, the presence of atrial fibrillation has been identified as an independent mortality risk factor in large population studies.

The impact of the selected entactogens and their o-quinone metabolites on the environment was explored in QSAR studies by the use of predicted molecular descriptors, ADMET properties and environmental toxicity parameters, i.e., acute toxicity in Tetrahymena pyriformis (TOX_ATTP) expressed as Th_pyr_pIGC
50/mmol L−1, acute toxicity in Pimephales promelas, the fathead minnow (TOX_FHM) expressed as Minnow LC
50/mg L−1, the acute toxicity in Daphnia magna (TOX_DM) expressed as Daphnia LC
50/mg L−1 and bioconcentration factor (BCF).

The formation of corresponding o-quinones via benzo-dioxo-lone ring, O-demethylenation was predicted as the main metabolic pathway for all entactogens except for 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)propan-2-amine (DiFMDA). The least favourable ADMET profile was revealed for N-(1-(benzo[d][1,3]dioxol-5-yl)propan-2-yl)-O-methylhydroxylamine (MDMEO).

QSAR studies revealed significant linear correlations between MlogP of entactogens and MlogP of o-quinone metabolites (R = 0.99), and Th_pyr_pIGC
50/mmol L−1 (R = 0.94), also their MlogPs with Minnow_LC
50/mg L−1 (R = 0.80 and R = 0.78), BCF (R = 0.86 and R = 0.82) and percentage of o-quinones’ yields (R = 0.73 and R = 0.80). Entactogens were predicted as non-biodegradable molecules, whereas the majority of their o-quinones were biodegradable.

Flavonoids are natural polyphenolic compounds present in a wide spectrum of plants that have a beneficial effect on human health. In the context of cardiovascular diseases related to plaque and thrombus formation, flavonoids exhibit an anti-aggregatory effect. Previously, it has been reported that all tested flavonoids exhibit an antiaggregatory effect on platelet aggregation when measured by impedance aggregometry on whole blood, in the test of aggregation induced by adenosine diphosphate (ADP). As not all flavonoids have the same targets within signaling pathways, an assumption of a common non-specific mechanism related to lipophilicity is to be considered. To test this hypothesis, reverse-phase thin layer chromatography was used to assess the lipophilicity of flavonoids; impedance aggregometry was used for testing of platelet aggregation and flow cytometry to monitor the influence of flavonoids on platelet activation. Lipophilicity analysis showed a highly negative correlation of logP and MINaAC for groups of flavones and flavanones. As determined by flow cytometry, the exposition of receptors necessary for the promotion of platelet activation and primary clot formation was diminished, i.e., lowered expression of the activated form of integrin αIIbβ3 was observed in the presence of flavanone. Platelet membrane stabilization by flavonoids as a mechanism of antiaggregatory effect has been supported by impedance aggregometry experiments when specific inhibitors of platelet aggregation signaling pathways (U73122, indomethacin, verapamil) were used in the presence of a weak (ADP) and a strong (TRAP-6) agonist of aggregation. While individual flavonoids can have specific targets within aggregation signaling pathways, all flavonoids share a common non-specific mechanism of platelet aggregation inhibition related to their lipophilicity and membrane stabilization that, to some extent, contributes to their antiaggregatory effect.

Published: October 2019

Four classes of aminoquinoline derivatives were prepared: primaquine ureas 1a–f, primaquine bis-ureas 2a–f, chloroquine fumardiamides 3a–f and mefloquine fumardiamides 4a–f. Their antiproliferative activities against breast adeno-carcinoma (MCF-7), lung carcinoma (H460) and colon carcinoma (HCT 116 and SW620) cell lines were evaluated in vitro, using MTT cell proliferation assay. The results revealed a low activity of primaquine urea and bis-urea derivatives and high activity of all fumardiamides, with IC
50 values in low micromolar range against all tested cancer cell lines.

The aim of this study was to evaluate long-term stability and assess the wound healing potential of the innovative melatonin-loaded lipid-enriched hybrid system compared to conventional melatonin-loaded chitosan microspheres. The hybrid system contained nanostructured lipid carrier incorporated in the chitosan matrix, in order to modify melatonin release and alter physicochemical characteristics of the delivery system. Stability testing was performed during a six-month period under two conditions: refrigerated (5 ± 3 °C) and at room temperature (25 ± 2 °C/60 ± 5 % RH). Samples stored at both conditions were analyzed in terms of particle size, zeta potential, moisture content and thermal properties. At the end of testing, drug content was determined in all samples. Dressings wound healing potential was assessed by in vitro scratch test using human skin fibroblast cell line. Although both systems showed good stability characteristics, the addition of lipids in the system has improved its wound healing potential.

Direct-seeded rice alternative to transplanted rice system is less labor intensive, easier to plant, and consume less water. The advantages of direct-seeded rice have been proved by many research workers, but yet it is not very much adapted by farmers. Weeds reduce cost effectiveness of direct-seeded rice. A study was conducted to evaluate the effect of different row spacing and weed management practices on the performance of aerobic rice at Agronomic Research Area, University of Agriculture, Faisalabad, during summer season of 2013. Fine rice variety ‘Super Basmati’ was used for experiment in a randomized complete block design with factorial arrangements with three replications. Hand drill sowing with row spacing comprised 15 cm, 22.5 cm, and 30 cm was practiced. Weed scouting hoeing (hand pulling is weed free treatment for comparison with the others and hoeing is a type of mechanical weeding) and pre-emergence herbicide, followed by post-emergence herbicide, were the weed management practices. Weeds data and rice yield parameters were measured. Maximum reduction in weed density (86%) and weed dry weight (79%) was recorded for pre-emergence, followed by for post-emergence herbicide in crop sown at 15 cm row spacing.

The goal of this paper is to propose a testing procedure for selected intrusion prevention systems (IPS) in a realistic network traffic in terms of their suitability on a given hardware microcomputers for low-performance devices for internet of things (IoT). We perform an IPS research in terms of resource usage in order to establish a universal procedure of checking, whether a given microcomputer controlling IoT devices (often in overloaded state) can additionally burden the installation and start-up of IPS. The experiment is repeated on several boards under overload condition to determine the maximum data rate, above which transmission degrades. The presented testing method is an exemplary tool for IoT applications concerning the security of embedded devices with low performance.

Students education in various fields (such as science, technology, engineering, and mathematics) is constantly looking for ways and techniques on how to motivate students to learn, how to increase their engagement and how to increase the e ciency of knowledge acquisition. Information and communication technologies are developing at a very rapid speed and o er many new opportunities that could be used for such purposes. This paper focuses on virtual laboratory technologies that could be very helpful for these learning problems especially for subjects that lose the interest of young people. We have conducted two pilots at a Slovak secondary school and university to analyse the usability of self-directed learning applied to teach networking topics such as software-defined networking and network functions virtualisation. This learning approach was enhanced by a developed virtual lab and a set of self-tests. Knowledge tests and questionnaires have been used to investigate the impact of this self-directed virtual lab-based learning approach on students motivation to learn, feelings, satisfaction with learning approach and knowledge gain. The results showed that students appreciated the virtual laboratory for improving learning and their motivation to learn and their knowledge acquisition was noticeably improved when the virtual lab was included.
