Penelitian ini bertujuan untuk menguji pengaruh good corporate governance (GCG), profitabilitas, dan ukuran perusahaan terhadap nilai perusahaan. GCG dalam penelitian ini diukur dengan menggunakan proksi kepemilikan manajerial. Profitabilitas diukur dengan menggunakan rasio profitabilitas return on equity (ROE), sedangkan ukuran perusahaan diukur berdasarkan Ln total aktiva. Variabel dependen dalam penelitian ini yaitu nilai perusahaan yang diukur dengan analisis Tobin’s Q.Data yang digunakan dalam penelitian ini berupa data sekunder yang berbentuk kuantitatif yang berasal dari laporan keuangan tahunan yang telah diaudit perusahaan manufaktur yang terdaftar di BEI tahun 2011-2016. Teknik pengambilan sampel pada penelitian ini menggunakan teknik purposive sampling dan didapati ada sebanyak 10 perusahaan yang terpilih sebagai sampel penelitian dari sebanyak 123 perusahaan yang diamati. Metode analisis data yang digunakan adalah analisis regresi linier berganda.Hasil dari pengujian hipotesis pertama (Ha1) menunjukkan bahwa variabel good corporate governance (GCG) tidak berpengaruh terhadap nilai perusahaan. hal ini terjadi karena struktur kepemilikan manajerial di Indonesia masih tergolong sangat kecil dan didominasi oleh sistem keluarga, serta pemilik manajemen perusahaan juga belum sepenuhnya bisa memberikan kepercayaannya terhadap manajemen perusahaan dalam hal jalannya perusahaan. Hasil pengujian hipotesis kedua (Ha2) menunjukkan bahwa variabel profitabilitas berpengaruh positif terhadap nilai perusahaan. Hal ini membuktikan bahwa semakin besarnya keuntungan perusahaan untuk membayarkan devidennya, maka akan berdampak baik pula bagi nilai perusahaan. Hasil pengujian hipotesis ketiga (Ha3) menunjukkan bahwa variabel ukuran perusahaan berpengaruh positif terhadap nilai perusahaan. Hal ini membuktikan bahwa jika dilihat dari sisi manajemen perusahaan, ukuran perusahaan yang besar akan menjadi suatu kemudahan yang dimiliki perusahaan itu sendiri dalam mengendalikan perusahaan yang juga akan diikuti dengan meningkatnya nilai perusahaan. Hasil pengujian pada hipotesis ke empat (Ha4) uji simultan menunjukkan bahwa variabel good corporate governance (GCG), profitabilitas, dan ukuran perusahaan secara bersama-sama berpengaruh positif terhadap nilai perusahaan.

Published: May 2019

Pengolahan pada Sistem informasi data kependudukan tingkat desa biasanya masih menggunakan sistem secara manual biasanya dengan menyimpan data-data dalam bentuk pembukuan ,Microsoft word ataupun excel. Sehingga terjadi beberapa kendala pada ketidakvalidan atau ketidakcocokan data. Sering pula terjadi kesalahan atau kelamaan untuk mencari informasi tentang pendatang dan kepindahan dari desa tersebut. Demikian pula pada penyediaan data, seperti pada data pendidikan ,data pekerjaan, dan data demografi penduduk yang sering tidak up to date. Berdasarkan pada kendala-kendala di atas, maka dibangun perancangan sistem informasi data kependudukan desa. Diharapkan dengan adanya aplikasi tersebut dapat membantu instansi pemerintah desa dalam melakukan pendataan penduduk. Dengan ini akan memudahkan dalam pencarian informasi data penduduk. Selain itu, aplikasi ini dapat membantu instansi pemerintah desa dalam memonitoring perkembangan penduduk dan menyelesaikan kendala-kendala yang ada sehingga pelayanan kepada masyarakat bisa lebih baik dan lebih optimal. Bahasa pemograman untuk pembangunan pada sistem ini menggunakan tool netbeans 8.2 dan android studio, sedangkan managemen basis data menggunakan database MYSQL. Pertimbangan pada pemilihan bahasa pemrograman Netbeans 8.2 karena Netbeans 8.2 terutama pada open Source sehingga aplikasi yang kita buat tidak bajakan yang biasa berjalan di OS mana pun dan juga menyediakan komponen- komponen yang lebih lengkap, lebih interaktif dan lebih mudah dalam mengoneksikan basis data MYSQL kedalam program aplikasi yang akan dibuat.

Authors: Ababsa Zine El Abidine , Derouiche Mohamed Tahar , Medjroubi Kamel , Akkal Salah
Published: May 2019

Tetraclinis articulata (Thuya of Barbary), endemic to North Africa, is used as a traditional medicine for the treatment of many diseases [1]. We investigated the antidiarrhoel properties of the butanol extract of Tetraclinis articulata (BETA) in male and female Swiss albino mice to support its traditional use. The antidiarrhoeal activity of the plant extract was evaluated in a model of castor oil-induced diarrhoea model in mice and compared to loperamide (a reference inhibitor of diarrhoea). The effect of (BETA) on gastrointestinal motility was determined by the oral administration of charcoal and Castrol oil-induced intestinal fluid accumulation (enteropooling).The (BETA) showed remarkable antidiarrhoeal activity significantly inhibited gastrointestinal motility and castor oil induced enteropolysis (68,18%), more than to the inhibition achieved in loperamide treated mice (60,16%). The second aim of the present study was to evaluate the anti-ulcerative activity of The (BETA), it produced percent protection of control colitis by 77, 40%, while the standard drug (aspirin) produced 81,39% protection. We conclude that Tetraclinis articulata extracts are potential sources of new anti-ulcer agents and antidiarrhoeal drugs.
Technological Development of a Yarn Grip System for High-Speed Tensile Testing of High-Performance Fibers
Authors: Unger Reimar , Schegner Philipp , Nocke Andreas , Cherif Chokri
Published: May 2019

Particularly in terms of carbon fiber (CF) rovings and further high performance fibers, it is a highly demanding task to clamp technical yarns with low elongations at break during high-speed tensile tests due to their sensitivity to shear stress. For fibers to be tested, a low elongation at break results in short testing times and requires high acceleration. In this paper, four different yarn grips that can be applied with various test machines will be introduced and compared to a wedge screw grip. By using most sensitive CF rovings, advantages and disadvantages of these gripping devices will be qualitatively evaluated by means of testing machines with test speeds of up to 20 m/s and strain rates of up to 200 s−1, respectively. Hence, the reproducibility and precision of test results were considerably enhanced by optimizing the geometry and mass of yarn grips. Moreover, theoretical approaches and calculations for the design of yarn grips suitable for test speeds of up to 100 m/s will be presented.

Central and Eastern Europe as Partner of Chinese One Belt One Road Project
Authors: Górski Grzegorz , Górska-Szymczak Joanna
Published: May 2019

The Chinese One Belt One Road initiative refers to the idea of the so-called New Silk Road. This ancient trade route connected Asia’s Far East with Europe from the earliest times. In various historical periods, this way of trade has often been interrupted by violent events and rivalry of hegemons that are changing in this huge space.

The current OBOR project assumes an important role of the countries of Central and Eastern Europe. It is an area that includes a large number of countries interested in intensifying cooperation with China and Asian countries.

However, the implementation of this project will certainly take many years. While the countries of this region are expecting quick infrastructural investments, in particular in the area of communication. This is a condition for the future success of the Chinese project.

On the other hand, there are many serious conflicts on the route of the planned route of major transport connections (i.e. in Syria, areas inhabited by Kurds). Without a long-lasting calming of this area, the implementation of this project will not be possible.
Entrepreneurial Behaviour on the New Silk Road: Space for Improvement?
Authors: Novosák Jiří , Jurčík Radek
Published: May 2019

A number of studies point out a positive influence of entrepreneurship on economic growth. This is due to the role that entrepreneurs play in the economy by utilizing new knowledge, shaping markets, and pushing out unproductive incumbents. The ambitious One Belt One Road Initiative, which recently includes sixty Asian, African and European countries, aims at stimulating global economic development and prosperity. From the theoretical point of view, entrepreneurship is crucial for achieving the aim. Consequently, the intent of this paper is to analyze entrepreneurial behavior of the countries participated in the One Belt One Road Initiative, using the data from the Global Entrepreneurship Monitor (GEM). Distinct country clusters are identified and their entrepreneurial characteristics are interpreted.
Shareholder value in Croatian banking sector
Authors: Huljak Ivan
Published: May 2019

The view on banks as investments in Croatia is challenged by two phenomena: dual holdings (owners are intensely involved in bank balance sheet as, apart from equity, they provide a significant portion of deposits and loans) and the impediments to determining the cost of equity (as only a handful of banks are traded and with questionable liquidity in the capital market). The paper contributes to the literature by applying the panel regression on the translog cost function in order to calculate the shadow cost of equity for banks in Croatia for the period from 1994 to 2016. In the next step, the Economic Value Added was calculated by taking into account the dual holding role of bank owners. The results suggest that the shareholders economic value is significantly different from the accounting value. In addition, it seems that the standard view that domestic banks are less profitable than foreign banks is only valid from the accounting perspective.
Life tables estimation for pension system actuarial projection model with insufficient data: case of Republic of Srpska
Authors: Bošnjak Nikolina , Prorok Vesna
Published: May 2019

This article provides an upgraded model for actuarial projection of the dependency ratio of the pension fund in the Republic of Srpska. The nonexistence of complete upto-date life tables presents a huge problem of the pension system and life insurance industry modelling in the Republic of Srpska. Therefore, this article tries to encompass the problem by using the life tables of the Republic of Croatia as a starting point for adjustment of age-grouped life tables available for population of the Republic of Srpska. The actuarial projection model for the Pension and Disability Insurance Fund of the Republic of Srpska is upgraded by using these adjusted life tables and the best estimate mortality trend for mortality forecasting. The results of the Republic of Srpska pension fund dependency ratio projections obtained using a forecast of adjusted life tables are compared to the previous research on this topic which used the life tables of the Republic of Serbia for 2013 for the same model. This way we can observe the effect of life expectancy growth on pension fund’s dependency ratio estimates as one of the measures of pension fund’s sustainability.

Published: May 2019

Ginkgo biloba L. is characterized by its high level of resistance to climatic conditions, diseases, and pests. In Slovakia, there is a rich collection of genetic resources of ginkgo consisting of 288 trees growing in 103 locations and providing valuable biological material for scientific research. There have been documented 45 trees of ginkgo older than 100 years (ranging from 112 to 242 years of age). Their dendrometrical parameters were recorded. For genomic imprinting, three types of microRNA-based markers were selected; highly conserved gb-miR160, moderately conserved gb-miR482 and the species-specific gb-miR75. The most efficient one can be considered the marker gb-miR482 with its genotype-unique miRNA profiles probably related to this marker functioning in the defence mechanisms of the ginkgo species. Unique miRNA loci were recorded in genomes of young ginkgo trees. We found that, by selecting the appropriate microRNA-based markers, it is possible to characterize the ginkgo genome in the context of microclimatic conditions.
The application of ergative verbs to avoid accusations in the translation of Chinese editorials into English
Authors: Dong Dahui , Yang Mu-Li
Published: May 2019

The use of ergative verbs results in the agent being backgrounded in an English sentence, and it is often used in the media together with other means such as the use of intransitive verbs, passives, and nominalized nouns to achieve the pragmatic purpose of accusation avoidance. A great deal of research has been done on the role of ergative verbs in media discourse in English as well as the acquisition of ergative verbs by learners of English as a Foreign Language (EFL). However, it remains unclear how EFL Chinese learners of advanced levels of competence, such as postgraduates of translation majors and professional translators, use ergative verbs when translating newspaper editorials from Chinese into English. Nor is it clear whether learners have acquired the requisite knowledge of ergative verbs in order to use them effectively so as to avoid blaming the agent of an action or process in translation. This study recruited 30 native Chinese-speaking translators who fell into three categories: undergraduate translators, graduate translators, and professional translators. A small parallel translation corpus was built, which consisted of 150 English translations of 5 Chinese editorials produced by the translators. Accusation-avoidance expressions in the source text and their translations were then extracted and input into an SPSS spreadsheet. The results show that the use of ergative verbs in translations by undergraduate translators is significantly higher than in translations by graduate and professional translators in terms of quantity. The results of the study may be useful for translation teaching and learning.
Learner autonomy dimensions: What motivated and unmotivated EFL students think

Published: May 2019

To counter the misunderstandings that students from East Asian countries like Japan are less autonomous than learners from other cultural backgrounds, this exploratory research examined Japanese university students’ attitudes toward their own responsibility and ability to study English autonomously. Student motivation was observed specifically to determine how students perceived their learning inside and outside the classroom. In this study, 958 students from 12 universities across Japan participated in a 24-item adapted questionnaire on learner autonomy. Based on the data collected, slight to not significant differences were revealed regarding students’ perceptions of responsibility to perform autonomous learning tasks. However, with regard to perceived ability to perform autonomous learning tasks, there were significant differences as motivated students demonstrated a far greater confidence in their capacity to be involved in their own learning than unmotivated students, yet they did not necessarily act on their ability to do so. These findings and their implications are explored and discussed.
Cultural context in parliamentary discourse with examples of parallel speeches in the polish Sejm and the German Bundestag – reflections from a translator’s perspective
Authors: Jurewicz Magdalena
Published: May 2019

The article presents examples of cultural references made by Polish MPs speaking in the Polish Sejm and German MPs speaking in the German Bundestag. The term “cultural context” will be used as defined by Boniecka (1994). There will be presented two examples of parliamentary speeches given in the Polish Sejm and the German Bundestag from a larger corpus of collected data for the purpose of the research on the appellative function of the word “wish”. The starting point for compiling texts was the minutes of the parliamentary debates of the Polish Sejm which contained the word “życzyć” (“wish” in Polish) and the minutes of parliamentary debates in the Bundestag which contained the word “wünschen” (‘wish” in German) in the first person singular and plural. The topic of the speeches had a secondary meaning. On the basis of the examples it discussed will be shown that parallel texts of MP’s speeches are a valuable teaching material in specialised language lessons.
Foreign language portfolio and EU funded foreign language courses in Poland
Authors: Kic-Drgas Joanna , Sikora-Gaca Małgorzata
Published: May 2019

Due to globalization processes, the importance of the knowledge of foreign languages in almost every field of professional and private life is constantly growing. This has had an impact on the policy of many international institutions, including those in the European Union. Supporting language pluralism has been an explicit aim of the European strategy for multilingualism since 2008. The following paper presents the results of an interdisciplinary research study initiated by representatives of two different fields of science: linguistics and political science. Among the generation of young people aged between 18-24, who belong to the so-called Generation Z (White 2017: 224) and were brought up as EU citizens, the study points to a conflict between the perception of foreign language skills and opportunities to develop them using EU funds. The research aims to analyze the awareness of the EU language policy in Poland, combining questions related to people’s foreign language portfolio and knowledge about existing possibilities of learning foreign languages, as well as the ability to obtain external financing. The survey was conducted among 100 students of linguistic and non-linguistic studies and enabled the formulation of initial conclusions that are the basis for further research.

Published: May 2019

Charge-carrier transport in the channel of bottom gate, top contact organic field effect transistors with anisotropic layers of 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-Pentacene) obtained by zone casting was investigated using scanning Kelvin probe microscopy combined with atomic force microscopy. The TIPS-Pentacene continuous layers consisted of thin crystals unidirectionally oriented in the channel. Devices with perpendicular and parallel charge flow in the transistor channel were prepared. It was found that irregularities in the surface morphology at the semiconductor layer in the transistor channel are correlated with the local potential profile, and that the channel resistance strongly depends on the orientation of the TIPS-Pentacene crystals.

Published: May 2019

This study focuses on the description of oxidation of CdTe monocrystal surfaces after selective chemical etching. Measurements of surface morphology of the oxides occurring in short time are valuable for deeper understanding of the material degradation and fabrication of reliable devices with enhanced performance. The samples with (1 1 1) orientation were selectively etched and cleaned of oxide. Exposure of the oxide-free surfaces of CdTe to air at normal atmospheric conditions over 24 hours leads to an appearance of characteristic surface features. The oxidized surfaces were investigated by scanning electron microscopy, scanning probe microscopy, Raman spectroscopy and ellipsometry. The results indicate clear differences in the oxidation of Cd-terminated and Te-terminated surfaces.

Authors: Samolińska Wioletta , Kiczorowska Bożena , Klebaniuk Renata
Published: May 2019

Introduction. The rate of aging and the possible coexistence of diet-related diseases are largely determined by the nutrition and lifestyle of the elderly. Therefore, it is important to assess the degree of coverage of organism demand for such nutrients as calcium and vitamin D in the elderly population.

Aim. The aim of the study was to determine the impact of age on calcium and vitamin D supply in daily alimentary rations of the elderly as well as their nutritional behaviour in terms of consumption of products which are the source of these nutrients.

Material and methods. The study involved 42 subjects aged from 60 to 85 years. The vitamin D and calcium content in daily food rations was assessed with the method of a 24-hour dietary interview carried out in triplicate.

Results. The nutrition of the elderly turned out to be inappropriate in terms of supplying the organism with calcium and vitamin D, and this was not age dependent. The average calcium and vitamin D supply in the daily food rations was estimated at 455.53 mg/day and 2.31 μg/day, respectively. The demand for calcium was covered in the range of 31-60% of RDA in over 60% of the elderly and the vitamin D demand was met in 30% of AI in over 80% of the subjects.

Conclusions. The assessment of the daily food rations indicates a necessity for increasing the intake of calcium- and vitamin D-rich food products and dietary supplementation with these components.

Urgency of the research. Activities in the field of compressed air drive unit design are the subject of research into alternative energies for automotive drive. The competition mentioned in this article is intended to stimulate universities and high school students to make material outcomes in this area of research. These activities bring new, sometimes unconventional solutions to problems that can potentially bring about solutions applicable in technical practice.
Target setting. The aim of this article was to map out possible ways of realizing a drive unit of a vehicle that is driven by compressed air. Based on an analysis of the most commonly used ways of solving this problem, the article indicates the direction of development of such a drive unit.
Actual scientific researches and issues analysis. Research in this area consists in designing a drive unit that would allow dynamic driving at low compressed air consumption. This requires the perfect mastering of the theoretical knowledge
about recirculation in compressed gas as well as the optimization of the power parameters of the unit by appropriate design of the basic construction component - linear pneumatic drive.
Uninvestigated parts of general matters defining. Only one group of transformation mechanisms is analyzed in the article that allow the compressed air drive unit to be constructed.
The research objective. The aim of the research is to provide a theoretical and mathematical basis for determining the optimum parameters of a compressed air propelled vehicle unit as well as its application for the construction of new vehicles
for competition.
The statement of basic materials. The basic material for the creation of the article was taken from the bachelor thesis of the co-author of the article [3], from the contest proposals and other sources available in the library and magazine materials
as well as from the prepared study materials for the students of the Technical University of Kosice, Slovakia.
Conclusions. Conclusions of the article lead to the determination of the appropriate concept of transformation of linear motion of the pneumatic drive to rotational in order to achieve the best results in the next year of the International Aventics
Pneumobile Competition.
DESIGN OF INDUSTRIAL ROBOT WITH INCREASED LOCOMOTION
Authors: Jánoš Rudolf , Dominik Dobiaš
Published: May 2019

Urgency of the research. One of the top trends in the field of mechanical engineering is automation. An inherent part of automation in today's businesses is industrial robots of various categories. In today's industrial production, human and robot are usually separated from each other in order to avoid potential collisions. Continuous development and the growing trend of robotics, in order to increase competitiveness, abandons this individual and isolated robot deployment and prevents group-building of human-robot workplaces.
Target setting. The reason for designing industrial robots with capacity around 5-10kg according to human anatomy is that the transition from semi-automated production (operating lines controlled by operators) to fully automated production requires industrial robots that have dimensions similar to human anatomy.
Actual scientific researches and issues analysis. The current production of robot devices reaches a high technical level, which is further enhanced by the continued development of their subsystems, but also by the upgrading of functional principles and elements that are involved in the architecture and morphology of these devices.
The research objective. To what extent is it possible for the work process to be mechanized or automated depends also on the level of development of the used equipment. In today's development stage, design of automated device is also automated.
The statement of basic materials: From the point of view of approaching the design of robots systems means a common sign is a mechatronic approach. Robots technical devices are a typical product with all the features of mechatronics (linking knowledge of engineering, management methods and artificial intelligence). This becomes the starting point for the elaboration of the methods of designing robots at all.
Conclusions. This article focuses on the design of the robotics devices, whose main task is to perform the assembly. The future of deploying human-robot collaboration has enormous boundaries and many variables that still need to be addressed. It is
important to remember that this technology is not about replacing people with robots. Rather, it is about using robust human features and robot strengths to achieve a new level of efficiency and productivity that could not be achieved by self-employment.
