Authors: Polláková Nora
Published: January 2019

Successful adaptation of introduced trees requires providing appropriate conditions for their growth and life. In this context, our study aim was a soil survey in the Arboretum Mlyňany, on the basis of which the soils could be classified. Detailed soil investigations were done at seventeen sites under dense monocultures of trees and the grassland. For each site, there was dug one soil pit, near which there were made three soil bores. Over most area of the locality, the prevailing soil-forming substrates were decalcified loess and silt, with gravelly patches, with prevailing medium soil texture, and acid to slightly acid pH. Based on the morphological features and the results concerning the physical and chemical soil properties, seven quality-degrees of soil cover were classified. The lowest-quality was recognised in Fragic Stagnic Retisol, in the highest-situated, east part of Arboretum, and also in the central part of the Ambrozy’s park under Thuja plicata, where there was discerned also low quality Albic Stagnic Luvisol. The most area east of the manor house is covered with Stagnic Cutanic Luvisol (the North American and East Asian area with Stagnic Cutanic Luvisol (Anthric)). North of the manor, on a slight slope of the North American area was found a Cutanic Luvisol (Anthric). West of the manor, the terrain evenly declines, and there has been developed Luvic Chernozem, whose cultivated form, Luvic Chernozem (Anthric), was determined in the East Asian area.

Published: January 2019

A study was conducted in an oak forest, to find out the relationship of stand structure, aspect and regeneration of species. Among all disturbance stands the density of banj oak Quercus leucotrichophora A. Camus individuals was peaked at 40–50 cm and 50–60 cm diameter at breast height (DBH) classes and low tree density was observed with the increasing DBH classes. North aspect showed higher density for most of girth classes as compared to south facing aspect. Among all the stands, low seedling density was recorded in undisturbed stand at south facing aspect as compared to the moderately and highly disturbed stands. The tree density of Q. leucotrichophora was higher in the undisturbed stand followed by moderately disturbed and highly disturbed stand. But in case of seedling density the higher density were observed at undisturbed and highly disturbed stand in both of the aspects.

Authors: Zrníková Petra , Bujalková Mária
Published: January 2019

The article presents theory and practice of teaching English for Medical Purposes. In the theoretical part, our study deals with role of the teacher and aspects of the learner’s autonomy in EMP teaching, communicative approach, and the development of academic skills such as reading a scientific article, listening to lectures, and giving a presentation. The practical part is divided into three sections. Students were tested for reading and listening for specific information as well as general understanding. The main factors which caused difficulties in listening comprehension (Skills Evaluation 1) are the speaker’s rate of speech, accent, the role of a listener, the type of language used, the context of situation, background noise and visual support. The analysis of the main errors in reading comprehension (Skills Evaluation 2) showed the incorrect use of prepositions, passive voice, tenses, specific medical and academic vocabulary, and discourse markers. Assessment of the most common weaknesses in presentation skills (Skills Evaluation 3) includes lack of confidence and eye contact, overuse of haptics, fearful body posture, and the inappropriate use of paralanguage.
Extracurricular Education Diversity in Czech Nursery Schools
Authors: Majerčíková Jana
Published: January 2019

This empirical study contributes towards a better understanding of the educational reality in kindergartens. It explores the after-school activities and interests of Czech nursery schools (NS) children. The topic focuses on the disharmony and subsequent fine-tuning of interests of both the family and the kindergarten, set against the background of parents’ requirements and the kindergarten’s reaction to them. The goal is to shed light on how kindergartens reflect parents’ requirements pertaining to their children’s extracurricular activities, the kindergarten’s perception and interpretation of this situation, and what sort of approach is used for implementation. The research and survey method used is content analysis. Fifteen kindergarten teacher thematic reports, 3,000-5,000 words each, and forty inspection reports, the results of Czech kindergarten inspections, were analyzed. The analytical techniques of Grounded Theory - open and axial coding - were used in the processing of the source materials. The results of the analysis set in a paradigm model depict the state of administration and relationships between variables, which determine after-school activities in kindergartens. It was demonstrated that kindergartens select various approaches when negotiating a solution to extracurricular activities. The educational reality then includes kindergartens that do organize after-school activities as well as those that do not. Kindergartens which do offer after-school activities, however, differ in the degree of acceptance of such programs in terms of need for child development and how they perceive the benefits of such an above-standard approach towards their customers.
Classroom Participation as a Performative Act of Language Learners’ Identity Construction
Authors: Lujić Rea
Published: January 2019

In the first part of this study, we briefly present different approaches used to define the concept of second language learners’ identity. Then we introduce Butler’s theory of performativity (1988) and we attempt to apply its main concepts as tools for describing L2 learners’ identity. In the second part of the study, we try to answer the following question: What are typical performative acts of a good and a poor language learner in the language learning classroom? Our research suggests that performing a good language learner identity refers to the learner’s frequent and repetitive participation in utterances whose content is related to the language classroom, regardless of the chosen communicative resources. As for performing a poor language learner identity, it appeared that it refers to the learner’s repetitive and frequent participation in utterances whose content is not related to the language classroom, regardless of the chosen communicative resources.
Comparison of the thermal stability of magnesium phosphate (newberyite) coating with conventional zinc phosphate (hopeite) coating
Authors: Pokorný P.
Published: January 2019

This article presents a detail comparison of the thermal stability of the new magnesium phosphate (newberyite – MgHPO4·3H2O) coating with a conventional coating of zinc phosphate (hopeite – Zn3(PO4)2·4H2O). It was confirmed that dehydration of zinc phosphate (hopeite) occurs gradually (dehydration start temperature: 115 °C). The start of magnesium phosphate (newberyite) dehydration is indeed shifted to somewhat higher temperatures (about 125 °C) but the dehydration has an intense jump character. When using magnesium phosphate (newberyite) coating for further surface treatment at higher temperatures, dehydration of the coating can result in reduction of the adhesion between the phosphate/primer coatings. Under these conditions, it is recommended to use a coating of conventional zinc phosphate (hopeite) or manganese phosphate (hurealite).
Effect of in Doping on the ZnO Powders Morphology and Microstructure Evolution of ZnO:In Ceramics as a Material for Scintillators
Authors: Muktepavela F. , Maniks J. , Grigorjeva L. , Zabels R. , Rodnyi P. , Gorokhova E.
Published: January 2019

Transparent ZnO ceramics are of interest for use as material for high-efficiency fast scintillators. Doping ZnO ceramics in order to improve complex of their properties is a promising direction. In the present research, the role of indium in the ZnO nanopowders surface interactions and in the change of microstructures and photoluminescence (PL) characteristics of sintered cera-mics is considered. Undoped and 0.13 wt% In doped ZnO ceramics are obtained by hot pressing sintering. It has been found that indium leads to the transition of initially faceted ZnO particles to rounded, contributing to good sintering with formation of diffusion active grain boundaries (GBs). Unlike ZnO ceramics, ZnO:In ceramics microstructure is characterised by the trans-crystalline mode of fracture, faceted GBs with places of zig-zag forms and predominant distribution of In at the GBs. Such indium induced modifications of GBs promote removal of point defects and reduce PL parameter α = Idef/Iexc in comparison with the undoped ceramics. Results characterise ZnO:In cera-mics with improved GBs properties as a prospective material for scintillators.

Authors: Pham Nhat Tan , Phan Quyen Phu Thi , Tučková Zuzana , Vo Nga , Nguyen Lien H.L.
Published: January 2019

The environmental concern has become an emerging topic in organization’s human resource management strategy, especially in improving employee’s environmental behavior at work. Thus, the organizational citizenship behavior toward the environment (OCBE) has been currently attracting scholars in management. However, published studies contain research gaps in investigation of the relationships between both green training and organizational culture and OCBE, especially in the hotel industry. Following the social exchange and Ability-Motivation-Opportunity theories, this study aims to examine the effects of two green practices on OCBE and the moderating role of green organizational culture to the effect of green training on OCBE. A quantitative approach with survey strategy is employed and conducted in 4-5 star hotels to test these relationships. The PLS-SEM and K-means Cluster Analysis techniques are applied to analyze data. The findings reveal that green training and organizational culture positively influence OCBE. Also, the effect of green training on OCBE is moderated by green organizational culture. Finally, our study provides limitations of research and further studies, and the implications for management practices concerned with improving employee’s voluntary eco-behavior in the hotel industry.
Romanian immigrants and the inflows of foreign direct investment towards Romania
Authors: Roman Monica , Strat Vasile Alecsandru
Published: January 2019

The answer to the following question summarizes the research presented in this manuscript: “Are Romanian immigrants in the EU countries enhancing the foreign direct investment (FDI) inflows towards Romania?”, and as a consequence it makes the results of the paper a useful tool for all Romanian authorities dealing with one of the two topics: migration and foreign investments. To our knowledge, the paper provides the initial evidence supporting the hypothesis that Romanian immigrants in the EU countries can be regarded as “ambassadors” of the Romanian economy in attracting FDI (to Romania) from their adoption countries. The methodological approach relies on econometric modelling which reveals a positive and statistically significant relationship between the stock of immigrants and the number of FDI firms located in Romania and sourced from 15 EU economies, when controlling for several variables. The results could be useful both for companies and for Romanian policymakers that should target as source for potential foreign capital the economies which attract important flows of Romanian immigrants.
The role of Romanian social enterprises in the alleviation of poverty and social exclusion
Authors: Argatu Ruxandra
Published: January 2019

Poverty and social exclusion are nowadays widely debated phenomena as they present highly threatening consequences for the wellbeing of humanity, making it unable to reach adequate living standards and to fully exercise social rights. To alleviate imbalances, adequate programs need to be put into place and for this process to be efficient, coherence and commitment must constitute elementary values to advance social welfare. Social enterprises can also contribute with their value creating potential to the fostering of a sustainable society that places a high emphasis on the defense of vulnerable groups and offers them an equitable treatment. The present paper firstly aims to illustrate conceptual elements referring to poverty, social exclusion and the social protection of marginalized groups. Secondly, the study is complemented by a research on Romanian social enterprises’ perspective (associations, foundations and sheltered units) concerning social threats and the defense of less favored individuals, undertaken through a questionnaire-based survey. The research unveils the social enterprises’ belief that the Romanian social field needs substantial attention from policymakers and that social protection services can aid them in gaining social privileges more adequately.

The Sturm Separation Theorem for Impulsive Delay Differential Equations
Authors: Domoshnitsky Alexander , Raichik Vladimir
Published: January 2019

Wronskian is one of the classical objects in the theory of ordinary differential equations. Properties of Wronskian lead to important conclusions on behaviour of solutions of delay equations. For instance, non-vanishing Wronskian ensures validity of the Sturm separation theorem (between two adjacent zeros of any solution there is one and only one zero of every other nontrivial linearly independent solution) for delay equations. We propose the Sturm separation theorem in the case of impulsive delay differential equations and obtain assertions about its validity.

On The Classification of Ls-Sequences
Authors: Weiss Christian
Published: January 2019

This paper addresses the question whether the LS-sequences constructed in [Car12] yield indeed a new family of low-discrepancy sequences. While it is well known that the case S = 0 corresponds to van der Corput sequences, we prove here that the case S = 1 can be traced back to symmetrized Kronecker sequences and moreover that for S ≥ 2 none of these two types occurs anymore. In addition, our approach allows for an improved discrepancy bound for S = 1 and L arbitrary.

When patients enter intensive care families have a variety of stressors such as rapid decision making and costs are not small. The role of nurse as educator is very important in reducing family anxiety with patients treated in intesive units. Mothers of intensive care babies feel a great deal of anxiety over their child's condition, so there needs to be a good system support for the healing of her and her baby. Various ways nurses do in reducing stress experienced by the patient's family such as good communication between nurses and families of patients with intensive care. This review aims to get a picture of stress management that can be done on the family of intensive care patients. Methods: A literature review was conducted in the fields of ebscho, sience direct, elseiver, sage journals, scopus, and proquest, limited the range of the last 10 years from 2007-2017. The final sample included 18 articles. Results: The literature found that the causes of family stressors include rapid decision-making, fear of family emergency conditions, maintenance costs and length of care. Good communication and good information and skill support can decrease the stress experienced by intensive care patients' families. Conclussions: Intensive care is a unit with high complexity, unstable conditions and sophisticated technology. Conditions that require rigorous monitoring not only cause stressors for the patient, but become a stressor for the patient's family.

Cashew tree (Anacardium occidentale L), contains flavonoid compound which plays a role in the medical treatment of Diabetes Mellitus because this compound has activity as an ?-glucosidase inhibitor. Brotowali stem extract (Tinospora cordfolia) demonstrated ?-glucosidase inhibitory (AGIS) activity. This research aimed to measure 96% ethanolic extract AGIS activity of brotowali-cashew apple combination (BJM). The research was conducted by using ELISA reader instrument at 405 nm for AGIS activity test. The IC50 was calculated from each sample. The IC50 of brotowali stem and cashew apple was 34,61 ?g/ml and 109,32 ?g/ml. Then, the combination of brotowali and cashew apple extract was mixed with each concentration of 0,5%. From 1:0, 1:2, 1:1,  2:1, and 0:1 BJM comparison resulted in AGIS power percentage averages of 84.05%, 69.51%, 70.92%, 68.10%, 40.37%. The results of this research indicated that brotowali stem has the potential as AGIS, while cashew apple has not any potential towards AGIS and that extract combination does not give synergic effect. Therefore, the use of a combination of brotowali-cashew apple extract is not as effective as the use of brotowali single extracts to inhibit the ?-glucosidase enzyme

Pembangunan infrastruktur transportasi jalan yang telah ditargetkan dalam program MP3EI diarahkan sebagai penghubung bagi titik-titik pusat lokasi potensial sumber daya alam. Pembangunan infrastruktur akan berpengaruh terhadap pergerakan orang dan barang utamanya pada transportasi jalan. Penelitian ini akan menganalisis dampak pergerakan yang ditimbulkan berupa bangkitan dan tarikan akan berpengaruh terhadap ketersediaan sarana dan prasanan transportasi jalan di Papua dan Papua Barat. Metode yang digunakan dalam penelitian ini adalah metode regresi linear. Hasil berupa pemodelan digunakan untuk memprediksi kebutuhan dan ketersediaan sarana dan prasarana transportasi jalan. Dari hasil penelitian pemodelan untuk angkutan orang adalah Y=516.623+0.021(penduduk)+l.01xl05(investasi)+O.l(panjang jalan)+0.007 (kendaraan) sedang untuk angkutan barang adalah Y=12393.84+0.073(penduduk)+7.79xl0·5(investasi). Pertumbuhan pergerakan dengan adanya program MP3EI yang didukung pembangunan jalan di Kabupaten Merauke sepanjang 511,4 km dengan investasi sebesar Rp 2.198 M dan Kabupaten Timika sepanjang 427,7 km dengan investasi Rp 3.171 M adalah 96%. Indeks aksesibilitas dan mobilitas dengan dan tanpa MP3EI masih dalam kategori sangat rendah. Ketersediaan sarana dengan kebutuhan AKDP yang ada di Papua dan Papua Barat adalah 130%, yang berarti bahwa jumlah armada saat ini pada umumnya melebihi kebutuhan yang ada. Namun dengan adanya program MP3EI maka kelebihan armada tersebut dapat dimaksimalkan sehingga mengurangi devisiasi kebutuhan dan ketersediaan sarana menjadi rata-rata 14%. Proyeksi pertumbuhan pergerakan angkutan barang adalah sebesar 85% jika dibandingkan dengan pergerakan barang tanpa adanya program MP3EI.

Pelabuhan Lembar adalah pelabuhan utama Lombok dan menangani muatan kecil, perahu nelayan dan kapal ro-ro yang melintas secara reguler ke Padang Bai, Bali. Dari tahun ketahun angkutan penyeberangan mengalami peningkatan, untuk kendaraan Roda-4 rata-rata sebesar 3,8%, dan kendaraan bermotor R-2 sebesar 34,5%. Dalam mengantisipasi peningkatan angkutan lintas penyeberangan Padang Bai – Lembar pada tahun 2012 dilayani 23 kapal penyeberangan yang mempunyai kapasitas muat penumpang  rata-rata  407 penumpang dan kendaraan R-4 rata-rata 22 unit. Dalam menganalisis kebutuhan area parkir kendaraan bermotor roda-4 dari tahun 2012 s/d tahun 2020 menggunakan program dinamis yaitupowersim, analisis data sekunder dan data primer menunjukkan bahwa fluktuasi angkutan sangat mempengaruhi kapasitas area parkir dan kapasitas muat kapal yang akan dioperasikan pada 3 (tiga) tahun terakhir menunjukkan fluktuasi angkutan, yaitu dari tahun 2009 s/d 2011, angkutan penumpang mengalami penurunan rata-rata per tahun 21.6 %, kendaraan bermotor roda-2 mengalami pertumbuhan sebesar 11.8 % dan kendaraan bermotor roda-4 mengalami pertumbuhan sebesar 11.4 %. Sedangkan Pelabuhan Lembar pada saat sekarang mempunyai kapasitas area parkir berjumlah 130 truk, waktu B/M 50-60 menit dan jumlah kapal yang melayani penyeberangan sebanyak 23 unit dengan rata-rata kapasitas muat kapal 22 unit. Pada tahun 2012 dengan pola kedatangan kendaraan R-4 38 unit/jam dan kapasitas muat kapal rata-rata 22 unit, maka jumlah kendaraan yang antri di area parkir berjumlah 68-69 unit. Tahun 2015 dengan pola kedatangan kendaraan R-4 46 unit/jam dan kapasitas muat kapal rata-rata 24 unit, maka jumlah kendaraan yang antri di area parkir berjumlah 94-95 unit.

Analisis Beban Kerja Mental Pilot Dalam Pelaksanaan Operasional Penerbangan Dengan Menggunakan Metode Subjective Workload Assessment Technique (Swat)
Authors: Saputra Abadi Dwi , Priyanto Sigit , Muthohar Imam , Bhinnety Magda
Published: January 2019

Beban kerja yang dialami oleh seorang pekerja dapat berupa beban fisik serta beban mental yang timbul dari lingkungan kerja. Beban kerja dirancang sesuai dengan kemampuan dan keterbatasan baik fisik maupun mental pekerja. Pengukuran beban kerja mental dilakukan menggunakan metode Subjective Workload Assessment Technique (SWAT), metode ini menggunakan tiga deskriptor, yaitu dimensi beban waktu (time), beban usaha mental (effort), dan beban tekanan psikologis (stress) dan dilakukan dalam dua tahap, yaitu tahap pembuatan skala dan tahap pemberian nilai. Penelitian ini bertujuan untuk mengetahui beban kerja mental pilot pesawat terbang terhadap dimensi-dimensi dalam penerbangan yaitu waktu, fase terbang, lokasi, dan cuaca, dan menidentifikasikan faktor apa yang paling dominan membentuk beban kerja mental. Hasil penelitian menunjukkan kondisi beban kerja mental pilot akan meningkat apabila dihadapkan pada kondisi penerbangan yang dilakukan pada dini hari (00.00.am–05.59 am), saat hari libur dan memasuki periodepeak season, serta pada saat pesawat terbang akan melakukan prosedur pendaratan, dan juga apabila terjadi perubahan kondisi angin dalam penerbangannya, yang akan semakin bertambah beban kerja mental seorang pilot jika dihadapkan pada kondisi pengoperasian pesawat (route condition ) dengan kondisi permukaan daratan yang memiliki kontur pegunungan. Secara keseluruhan pilot lebih mementingkan faktor waktu dalam mempertimbangkan faktor beban kerja mental.

Tujuan melakukan penelitian adalah untuk mendapatkan informasi mengenai strategi penyediaan dermaga yang sesuai dengan manajemen transportasi. Berdasarkan hasil analisis dengan menggunakan metode Analisis Deskriptif Kualitatif dan Kuantitatif, Strategi Penyediaan Dermaga dan Pemilihan Lokasi Pelabuhan, maka kesimpulan dari penelitian ini adalah Dermaga Pasar Gayam yang terletak di Sungai Kelay dengan adanya kebijakan daerah akan dialihfungsikan menjadi dermaga pariwisata, hal ini merupakan kebijakan pemerintah daerah Kabupaten Berau dalam upaya pengembangan pariwisata. Berdasarkan kondisi tersebut maka perlu dilakukan relokasi Dermaga Pasar Gayam yang selama ini berfungsi melayani bongkar muat barang dan lokasi yang direncanakan adalah di bantaran Sungai Segah yang termasuk dalam wilayah Kecamatan Teluk Bayur. Permasalahan yang ditemukan dalam penelitian adalah perencanaan pembangunan dermaga di lokasi yang baru masih lemah. Setelah dianalisis dan evaluasi manfaat pembangunan dermaga sungai dengan pendekatan manajemen transportasi yaitu strategi penyediaan dermaga dan Peraturan Pemerintah Nomor 61 Tahun 2009 tentang Kepelabuhanan, kondisi lokasi tersebut sudah sesuai, oleh karena itu pada prinsipnya pembangunan dermaga di lokasi tersebut dapat dilakukan sepanjang tidak ada masalah dalam pembebasan tanah atau lahan dan sudah dianggarkan dalam RAPBD Kabupaten Berau tahun 2015.Namun dari sisi perencanaan masih lemah karena belum ada dukungan hasil studi kelayakan,amdal, rencana induk dan desain detail sebagaimana yang dipersyaratkan peraturan perundangan tentang Kepelabuhanan dokumen yang terkait dengan perencanaan tersebut sebelum pembangunan dilakukan perlu dipenuhi.
The Bedoun Archive: A Public Archive Created for the Northern Tribes Bedouin of Kuwait
Authors: Kennedy Nour al Deen Susan
Published: January 2019

This article describes the creation of the Bedoun Archive at the Australian Data Archive, managed by the Australian National University.Â The Bedoun are a Bedouin minority comprising stateless members of the main tribes of Kuwait. They have been subjected to â€œOtheringâ€ in scholarly literature, indicative of both Orientalism and neo-Orientalism, approaches that have contributed to their oppression by the state and omission from the official histories of Kuwait and the academic literature.Â The theory and methodology behind the creation of the Bedoun Archive, based on the principles of humanistic sociology and collaborative research with Indigenous Peoples, are discussed. The archive provides safe storage for data analysed in the project, which can be used by others in future.Â This article contributes to improving understanding of the impact of Orientalism and neo-Orientalism on perceptions of the people and history of the Middle East in general, and the Arabian Gulf and Kuwait in particular. It also contributes new knowledge regarding the complex situation currently faced by the Bedoun, the role of intellectuals in the Arab Spring social movement and subsequently, their contribution to developing formal systems of knowledge about their own culture.
