Authors: Nosova N. V. , Golovneva L. B.
Published: July 2019

A revision of Sphenobaiera biloba Prynada from Northeastern Asia is based on restudy of the type material from the Zyryanka River Basin (Prynada’s collection), as well as additional specimens from the type locality (Samylina’s collection) and collections from the Ul’ya and Anadyr rivers. A new extended diagnosis of S. biloba based on the leaf morphology and epidermal structure is proposed. Geographic and stratigraphic distribution of this species in Northern Asia is discussed. S. bilobais known in the Aptian of Eastern Siberia (Lena River Basin) and from the early-middle Albian to Coniacian of northeastern Russia. In the Late Cretaceous this species was considered as relict and related with volcanogenic deposits of the Okhotsk-Chukotka volcanic belt.
The genus Birisia (Dicksoniaceae) in Cretaceous flora of Siberia and North-East of Russia
Authors: Grabovskiy A. A. , Golovneva L. B.
Published: July 2019

In the result of the re-examination of type material of the genus Birisia from the Cretaceous deposits of Siberia and North-East of Russia, we include only three species in this genus: B. alata (Prynada) Samylina (early-middle Albian — Coniacian), B. onychioides (Vassilevskaja et Kara-Mursa) Samylina (Aptian), and B. acutata Samylina (early-middle Albian). Species B. ochotica and B. alata are united under the name B. alata. Species B. jelisejevii, B. samylinae and B. oerstedtii are excluded from the genus Birisia as mismatching to the generic diagnosis. Species of Birisia are distinguished each other in size and degree of dissection of pinnules, in shape, presence and number of lobes, as well as the number of branches of the lateral veins inside the lobes. The pinnules of the Birisia are characterized by the significant variability and have a slightly different structure depending on their location on the leaf blade. Therefore, for a more accurate species identification of Birisia, it is necessary to have the most complete leaves with branching of two or three orders and the fertile pinnules.

Published: July 2019

Tulisan ini bermaksud untuk mengingatkan kita kembali terhadap teks-teks yang terdapat pada Kitab Suci berbagai agama di dunia yang dikenal dengan sebutan kaidah emas (Golden Rule). Teks-teks dimaksud merupakan prinsip-prinsip etika yang bersifat universal yang ditawarkan oleh agama-agama sebagai upaya memelihara dan memperkuat kehidupan masyarakat yang majemuk (multikultural) secara umum, dan pada khususnya di Maluku. Melalui kaidah emas ini, agama-agama henda menyadarkan dan mengingatkan para penganutnya untuk memperlakukan orang lain sebagai mana ia ingin orang lain memperlakukannya. Dengan demikian, kaidah-kaidah emas ini hendak menekankan aspek pro-hidup (berpihak kepada kehidupan) di mana semua manusia berdasarkan pada ajaran agamanya masing-masing, dapat saling menghargai dan melindungi orang lain yang berbeda darinya, khususnya di Maluku pasca konflik sosial yang pernah melanda daerah ini.

Experimental demonstration of data predictive control for energy optimization and thermal comfort in buildings
Authors: Bünning Felix , Huber Benjamin , Heer Philipp , Aboudonia Ahmed , Lygeros John
Published: July 2019

Model Predictive Control for room temperature control in buildings is an effective approach to energy management in buildings. However, the development and maintenance of physical models may be a bottleneck for widespread real life application. Data Predictive Control is an attempt to address this problem by learning the behaviour of the building from historical data and thus reducing the modelling effort. Here, we present an application of a Data Predictive Control approach, based on Random Forests with affine functions and convex optimization, to control the room temperature in a real life apartment. When compared to a conventional hysteresis controller, the applied approach saves 24.9 % of cooling energy while reducing the integral of comfort constraint violations by 72.0 % in a six-day experiment.
Can you reach for the planets or grasp at the stars? – Modified noun, verb, or preposition constituents in idiom processing
Authors: Smolka Eva , Eulitz Carsten
Published: July 2019

Idioms are a special case of multi-word expressions in that their meaning cannot be compositionally constructed from the meaning of the single constituents. The question of how the idiomatic meaning is assembled remains an unsettled issue in psycholinguistic research. The present study examines whether the figurative meaning of an idiom is recognized if critical idiomatic constituents, such as the noun, verb, or preposition, are modified. In three paraphrase experiments, participants saw (a) the canonical idiomatic phrase (e.g., She reached for the stars), (b) the idiomatic phrase with a modified constituent (e.g., She reached/grasped for/at the stars/planets), or (c) a matched literal control sentence (e.g., She reached for the sweets) and rated on a scale from 1 (not at all) - 7 (completely) how strongly the sentence reflected the meaning of a paraphrase of the idiom (e.g., She has always aspired to unattainable goals). Sentence type and constituent type strongly affected paraphrase ratings with highest ratings for canonical idiomatic phrases, lowest ratings for control sentences, and ratings in between for idioms with modified constituents. Further, idioms with modified verbs were rated higher in matching the figurative meaning than idioms with modified prepositions or nouns. Overall these findings indicate that the figurative meaning was assembled in spite of the modifications. We conclude that idioms are not fully ‘semantically fixed’ but allow for some flexibility in the processing of idioms. Modified constituents that activate meanings similar to those of the canonical constituents will co-activate the figurative meaning of the idiom together with the other idiomatic constituents. We discuss psycholinguistic models on idiom comprehension.
Veil-of-Ignorance Reasoning Favors the Greater Good
Authors: Huang Karen , Greene Joshua D. , bazerman max
Published: July 2019

The “veil of ignorance” is a moral reasoning device designed to promote impartial decision-making by denying decision-makers access to potentially biasing information about who will benefit most or least from the available options. Veil-of-ignorance reasoning was originally applied by philosophers and economists to foundational questions concerning the overall organization of society. Here we apply veil-of-ignorance reasoning in a more focused way to specific moral dilemmas, all of which involve a tension between the greater good and competing moral concerns. Across six experiments (N = 5,785), three pre-registered, we find that veil-of-ignorance reasoning favors the greater good. Participants first engaged in veil-of-ignorance reasoning about a specific dilemma, asking themselves what they would want if they did not know who among those affected they would be. Participants then responded to a more conventional version of the same dilemma with a moral judgment, a policy preference, or an economic choice. Participants who first engaged in veil-of-ignorance reasoning subsequently made more utilitarian choices in response to a classic philosophical dilemma, a medical dilemma, a real donation decision between a more vs. less effective charity, and a policy decision concerning the social dilemma of autonomous vehicles. These effects depend on the impartial thinking induced by veil-of-ignorance reasoning and cannot be explained by a simple anchoring account, probabilistic reasoning, or generic perspective-taking. These studies indicate that veil-of-ignorance reasoning may be a useful tool for decision-makers who wish to make more impartial and/or socially beneficial choices.
Social Origin, Field of Study and Career Progression: Heterogeneity in Graduates’ Occupational Mobility
Authors: Jacob Marita , Klein Markus
Published: July 2019

Research on stratification and mobility has consistently shown that there is a direct impact of social origin on occupational destination net of educational attainment even for degree-holders. However, only a few studies applied a longitudinal and dynamic perspective on how intergenerational mobility shapes graduates’ working careers. Using multilevel growth curve modelling and data from the 1970 British cohort study (BCS70), we contribute to this research by looking at the emergence of social inequalities during the first ten years since labour market entry. We further distinguish between graduates of different fields of study as we expect social disparities to develop differently due to differences in initial occupational placement and upward mobility processes. We find that parental class does not affect occupational prestige over and above prior achievement. Separate analyses by the field of study show that initial differences in occupational prestige and career progression do not differ between graduates from different classes of origin in STEM fields and arts and humanities. It is only in the social sciences that working class graduates start with lower occupational prestige but soon catch up with their peers from higher classes. Overall, our results indicate no direct effect of social origin on occupational attainment for degree-holders once we broaden our focus to a dynamic life course perspective.

Published: July 2019

Parents' involvement has a huge influence on children’s educational engagement during the elementary years, the study sought to examine the perceptions of Albanian parents of their involvement in their children's schooling at the Qemal Stafa School in Albania. The parental involvement construct examined in the study was conceptualized based on Epstein’s (1995) six categories of parental involvement comprising parenting, communicating, volunteering, learning at home, decision-making, and collaborating with the community. The data collected through the questionnaire were analyzed using descriptive statistics, Pearson correlation and ANOVA. The results showed a high level of parental involvement in the Albanian children’s learning development. The parents surveyed reported volunteering in many workshops that the school conducted. In addition, the results indicated that some parents maintained a good communication with teachers. The ANOVA results showed statistically significant differences in parental involvement by age, marital status, education level, Income Level. Variables such as communicating, and volunteering were identified as the most important components of parental involvement.

Authors: Anh Do Hong , Anh Nguyen Viet
Published: July 2019

In coastal areas and islands, farmlands often lack of nutrients. This research assessed the precipitation of phosphorus presenting in urine in the form of struvite of magnesium ammonium phosphate (MAP) by adding of supplement of  Mg2+ ion from MgCl2 solution contained in seawater (Cat Ba island area). The urine and seawater have been mixed at different ratios. The results have shown [Mg]:[PO4] ratios ranging from 0.75 to 5.26 allowed the precipitation of more than 90% of the phosphorus in the urine. Seawater – to – urine ratios of 0.67/1, 1.3/1, 3.2/1, 5/1, 7/1 and 9/1 in volume would give phosphorus recovery efficiency of 99%, 92%, 96%, 96%, 95% and 99%, respectively. Seawater in the studied area could be an appropriate Mg2+ ion source to produce MAP from urine diverting dry toilets. Recovered phosphorus can be used as slow releasing fertilize for farming.

Keywords: MAP: phosphorus recovery; seawater; urine; struvite.

Static analysis of four-parameter functionally graded plates with general boundary conditions
Authors: Phuong Hoang Thu , Quoc Tran Huu , Hien Ho Thi
Published: July 2019

In this study, the Ritz variational method is used to analyze and solve the bending problem of rectangular functionally graded material plate with general boundary conditions and subject to some types of load distribution over the entire plate domain. Based on the Kirchoff plate theory, the equilibrium equations are obtained by minimizing the total potential energy. The material properties are assumed to be graded through the thickness of the plates according to a power law with four parameters. The accuracy of the solution has been checked and validated through different comparisons to that available literature. A wide variety of examples have been carried out to reveal the influences of different geometrical parameters, FGM power law index, type of load distribution and boundary conditions on the bending responses of the plates. The results show that the gradients in material properties play an important role in determining the response of the FGM plates.Keywords: FGM; Kirchhoff plate; Ritz method; boundary conditions.
Weight optimisation of functionally graded beams using modified differential evolution
Authors: Anh Pham Hoang , Duong Tran Thuy
Published: July 2019

In this article, an efficient numerical approach for weight optimisation of functionally graded (FG) beams in the presence of frequency constraints is presented. For the analysis purpose, a finite element (FE) solution based on the first order shear deformation theory (FSDT) is established to analyse the free vibration behaviour of FG beams. A four-parameter power law distribution and a five-parameter trigonometric distribution are used to describe the volume fraction of material constituents in the thickness direction. The goal is to tailor the thickness and material distribution for minimising the weight of FG beams while constraining the fundamental frequency to be greater than a prescribed value. The constrained optimisation problem is effectively solved by a novel differential evolution (DE) algorithm. The validity and efficiency of the proposed approach is demonstrated through two numerical examples corresponding to the four-parameter distribution and the five-parameter distribution.Keywords: FGM beam; lightweight design; frequency constraint; differential evolution.
Application of Hilbert Huang transform to identify the natural frequencies of steel frame
Authors: Trung Nguyen Thanh
Published: July 2019

Identification of dynamic structural characteristics such as natural frequency based on measured vibration responses at site is one of the important steps in the structural investigation work of loading test and structural health monitoring. During the service stage, the dynamic characteristics can be changed due to the stiffness reduction and nonlinear of structure under extrema excitation. Therefore, the identification of instantaneous parameters of structure is very necessary in detecting and monitoring the structural deterioration continuously by the time. This paper presents the data processing method using Hilbert Huang Transform (HHT) algorithm in determining a time-dependent frequencies of steel frame. The vibration experiment for steel frame was conducted in this study. The acceleration responses in time domain were recorded and analyzed by HTT to determine the fundamental natural frequencies of frame. The instantaneous frequencies in the time domain of steel frame are the main finding in this research. The traditional data processing method using a Fast Fourier Transform (FFT) was conducted and compared with the HHT method.

Keywords: Hilbert Huang Transform (HHT); steel frame; Fast Fourier Transform (FFT); natural frequency.

Authors: Long Hoang Vinh
Published: July 2019

In the world, waste glass is widely recycled, especially in developed countries with a recycling rate of about 30-90%. Currently, in Vietnam glass emissions in urban areas account for 1.5-2% of solid wastes; however, few studies mention this waste. Therefore, light weight concrete (LWC) using foam glass granulates (FGG) is the object of this paper. In the study, the raw materials are FGG, But Son PC40 cement, Pha Lai fly ash and Sikament superplasticizer named R4. The experimental results show that with FGG content of 50% (by volume), the LWC’s bulk specific gravity is 1302 kg/m3 and compressive strength at 28 days is 89 kG/cm2.

Authors: Thuy Pham Thi
Published: July 2019

The paper aims to study the effect of operating conditions in the column experiment with the ion exchange material which was prepared in optimum synthesized conditions. Polystyrene waste from disposable food packaging was dissolved in cyclohexane and sulfonated by sulfuric acid to synthesize cation exchange materials which were applied to remove Cr3+ in water by the ion exchange principle. The optimum conditions for this method were found out and described in previously published literature of the author. Characterization by SEM and Fourier Transforms Infrared (FT-IR) spectroscopy proved that the additional Sulfonic groups were presented. The efficiency of Cr3+ removal was highly affected by column bed height, initial ion concentrations and flow rate of effluent. The highest efficiency of material was 84.0% with a material bed height of 10 cm in the removal of Cr3+ from simulated wastewater containing initial Cr3+ concentration of 120 mg/l. The experimental data obtained from this study was consistent with Thomas and Yoon-Nelson kinetic models, which will be applied for column design in practical study and design. The results from this method can help reduce the plastic waste and easy to apply in practice for removal of Cr3+ in wastewater.

The Swiss forest between wood supply and multifunctionality (essay)

Swiss forestry operations have been in deficit for decades. Timber prices fall while production costs rise. At the same time, demand for non-market forest services continues to increase. The challenge is to ensure a sustainable timber supply from Swiss forests in the future, while taking into account the multifunctionality of the forest. According to the results of a Swiss national science foundation research project on this issue, non-market forest services are highly valued by the population. The study also identified significant potential for improving the performance of forest operations, in particular by achieving economies of scale. In addition, the exploitation and maintenance of the forest has positive externalities, which justifies the payment of targeted public subsidies to the forest sector.

Published: July 2019

Dana 3. studenoga 1969. započeo je s radom novootvoreni Odjel za neuropsihijatriju tadašnjega Medicinskog centra Karlovac, čime je omogućen sveobuhvatan i suvremen pristup osobama sa psihičkim smetnjama. Otvorenju je prethodio završetak izgradnje prve etape nove karlovačke Bolnice na Švarči. Do tada je psihijatrijska skrb bila insuficijentna, unatoč entuzijazmu pojedinaca poput dr. Andrije Štampara koji je 1912. i 1913. djelovao u Karlovcu. Prvo desetljeće rada Odjela obilježilo je opterećenje „miješanjem“ psihijatrijske i neurološke kazuistike, ali i vodstvo erudita, prim. dr. Dražena Neimarevića. Poboljšanje uvjeta rada uslijedilo je 1980. osnivanjem zasebnih odsjeka, a dodatni pomaci u skrbi realiziraju se osnivanjem dnevnih bolnica za alkohologiju i psihoterapiju. Kvalitetniji pristup pacijentima posebno se postiže osamostaljivanjem psihijatrijske službe 1994. godine. Početkom 21. stoljeća inovativni iskoraci učinjeni su otvaranjem prve ambulante za liječenje seksualnih poremećaja u Hrvatskoj te uspostavom jednog od prvih mobilnih psihijatrijskih timova u okviru nacionalne implementacije modela psihijatrije u zajednici. Obilježavajući 50. godišnjicu osnivanja Odjela za neuropsihijatriju Opće bolnice Karlovac, preostaje zahvaliti svima koji su dali svoj doprinos razvoju psihijatrijske službe. Na tim temeljima valja prilagođavati i poboljšavati pristupe osobama sa psihičkim smetnjama, a s ciljem njihova kvalitetnog oporavka i destigmatizacije. Na kraju, prateći prilike u hrvatskoj psihijatriji i paralelne procese u komparativnim ustanovama, prikaz „karlovačke Psihijatrije“ može poslužiti i kao ogledni primjer razvoja drugih ustanova u sličnim županijskim/regionalnim centrima.

The influence of the peg-40 hсo concentration on the essential oil dispersion degree was studied with microscopic method.

Considering influence of the auxiliary substances and nettle juice concentration on the gel-mask structural viscosity, the ingredients’ correlations were selected which reached the required viscosity limit for gels (2 000–10 000 mpa∙s), namely: carbopol ultrez 10 and sodium alginate by 0.5 %, potassium sorbate – 0.1 %, nettle juice – 10–20 the optimal concentration of nettle juice was 15%. It was justified by the results of the study of the antioxidant properties of the experimental samples on paramecium caudatum infusoria. The conducted microbiological studies confirmed the effectiveness of the application of 0.1% potassium sorbate preservative, which meets the requirements of criterion a for the USP 2.0. The influence of solubilizer peg-40 hco on the degree of mixture of essential oils dispersion when distributed on a gel basis was studied. it was confirmed that the optimal concentration of PEG-40 hco is 0.4%, namely the ratio 1:1 according to the content of the perfume.

According to the complex experimental researches, the optimal composition of the gel-mask with nettle juice intended for telogen effluvium cutaneous application has been worked out.
The Mental health between epigenetics and individual beliefs
Authors: Dramnescu Marin
Published: July 2019

Mental health is an integrative concept that is not limited to dysfunctions or accentuations of psychic processes or mechanisms of thought. The research effort focused on the idea that mental health is a functional optimum found at the intersection of cellular behavior, the physical environment, the external environment, with all its subtypes, the environment in which the individual manifests itself and the subjective, psychological environment, dominated mainly by unconscious behavioral routines, beliefs, values, and ultimately individual perspective on life. Mental health represents and manifests itself as an emerging process resulting from the correlated functioning of the biological, physiological, and in particular cellular mechanisms, the various, random and / or permanent influences and stimuli of the physical, social and professional environment and the superior motivational structures of the type of beliefs and individual perspective on life. Epigenetics is a contemporary discipline derived from genetics that includes the environmental context as an important part of heredity. Currently, this discipline strongly influences a variety of areas, including medicine, psychiatry and psychology.

Published: July 2019

The phenomenon of university dropout is met in all universities in the world and its effects are felt both at the economic level, at the level of society and at the personal level of students who abandon the university. Factors leading to university dropout may be of a social nature (student background, income level, so on.), psycho-pedagogical (inadequate academic training, inconsistency between prior training and university studies, lack of counseling services, so on)and personal (poor adaptability to the university, low levels of socio-emotional intelligence, so on). Universities need to cope with this phenomenon and adapt and develop prevention and intervention services so that students' retention rate rises. The paper analyzes this phenomenon in The Bucharest University of Economic Studies and identifies possible solutions for diminishing the phenomenon.

This paper examines the effect of tax treaty, so called Perjanjian Penghindaran Pajak Berganda (P3B), on foreign direct investment inflow to Indonesia in short, middle and long term. From 67 countries that have P3B with Indonesia, we work only with 51 countries because of no longer P3B exist or lack of completed data. Using panel data set of 51 countries from 2000 to 2015 and applying fixed effect model, we find that P3B has insignificant relationship to foreign direct investment inflows in short term. However, tax treaty, both in middle and long term, have a positive relationship on Indonesiaâ€™s foreign direct investment inflow with 10%and 1% significant level, respectively. Furthermore, the data show that in all term there are Rp0 foreign direct investment inflow from corresponding countries, which are 58% countries in short terms, 61% in middle term, and 64% in long term. From all those countries that has no investment agreement, majority of them are lower middle income countries. So, Government should evaluate tax treaty that are present and consider more about macroeconomics factor from partner country before signing an agreement.

In the circumstance of the Chinesse emigrants going abroad to seek shelter and find new lands, especially southeast Asia, Dang Trong of Dai Viet kingdom has gradually become a point of arrival which attracts them strongly. Depending on geographic position of contigous sea and advantage of Dang Trong context at home and abroad, Chinese merchants and emigrants have come to the central coastal parts (especially in Quang Nam, Quang Ngai, Binh Dinh, and Phu Yen). Having settled in southeast Asia region as well as in the central part of Vietnam, Chinese emigrants have preseved their traditional culture to gain achievements in this land region. Besides, they have actively integrated into native communities, exchanging culture for prosperity and development. This paper indicates cultural exchanges, integration and development of the Hoa in the central coastal provinces in history and present, which asserts their contributions in the fields of culture, economy and society to build Vietnam nation, notably in the age of present international integration.

Introduction. An assessing of the sportsman's physiological reserve (PR) and its dynamics is important when planning and carrying out a training, forecasting sportsman's results. An importance of this problem increases in highperformance sports, and energy consumption sports. A complexity of solving of this problem is caused by the requirement of taking into account of the complex of the biomedical parameters and formation of an integral parameter. This parameter reflects functioning of various body systems which provide significant income to the sportsman’s result achievement. Objective. Development of the method and the system of PR assessing allowing complex investigation of the PR during the training process. Method and materials. For achievement of the aim the tasks were formulated and solved using methods of biomedical research and engineering, mathematical processing and analysis of the diagnostically valuable parameters. Results. The complex of the biomedical parameters reflecting sportsman’s body metabolism in condition of physical exercises is formed. They are the heart rate, the heart rate variability, the pulse frequency, the systolic and diastolic pressure, the respiratory rate, the blood saturation, and the stress index by Baevsky. It is important for PR assessing to assess parameters characterizing sportsman’s physiological reserves at the current moment and its dynamics. The circle diagram is proposed for taking into account of all mentioned parameters and its variation dynamics. The value of the integral PR parameter is an area of a polygon, which is obtained on the circle diagram using normalized values of the diagnostically significant parameters. The method of biomedical investigation of the sportsman and the method of PR assessing based on the complex of the body system parameters are developed. The scheme of assessing of sportsman's body physiological reserves before and after the training is proposed. The scheme allows to assess not only sportsman's body energy consumption during the training but also its recovery after the training. General structures of the biotechnical system and a structures of systems of picking up, registration, processing, and analysis of biomedical signals for assessing of sportsman's physiological reserves are developed. Special attention is given to the development of a wearable device for synchronous registration of the complex of biomedical parameters and algorithms of assessing of the diagnostically significant parameters of sportsman's body physiological reserves. Conclusion. The proposed method of sportsman's physiologic reserves investigation and the structure of the system with spatially distributed architecture allow sport medicine doctor and coach to assess an efficiency of sportsman's training process with respect to his potential capabilities, and efficiently control the training process.
MATHEMATICAL MODELS OF THE RADAR SIGNAL REFLECTED FROM A HELICOPTER MAIN ROTOR IN APPLICATION TO INVERSE SYNTHESIS OF ANTENNA APERTURE

Published: July 2019

Introduction. The basis for solving the problem of aircraft recognition is the formation of radar portraits, reflecting the constructive features of aerial vehicles. Portraits, which are radar images of the propellers of aerial vehicles, have high informativeness. These images allow us to distinguish the number and relative position of the propeller blades, as well as the direction of its rotation. The basis for obtaining such images are mathematical models of reflected signals. Objective. The aim of this paper is to develop mathematical models of the radar signal reflected from the helicopter main rotor applied to inverse synthetic aperture radar (ISAR). Methods and materials. ISAR processing is used to produce a radar image of a propeller in a radar with a monochromatic probing signal. The propeller blades in the models are approximated by different geometric shapes. The models used to describe the reflection from the propellers of helicopters and fixed-wing aircraft have significant differences. In the process of moving each blade of the helicopter main rotor makes characteristic movements (flapping, dragging, feathering), as well as bends in a vertical plane. Such movements and bendings of the blades are influence the phase of the signal reflected from the main rotor. It is necessary to take the phase change of the reflected signal into account as accurately as possible when developing an ISAR algorithm for imaging the main rotor. Results. We found that in the centimeter wavelength range the mathematical model of the signal reflected from the helicopter main rotor as a system of blades is most accurately described by representing each blade with a set of isotropic reflectors located on the main rotor’s blade leading and trailing edges. Taking into account the flapping movements and curved shapes of the blades in the model allows you to get as close as possible to the features of the real signal. Conclusion. The developed model which takes into account the flapping movements and bends of the helicopter main rotor blades can be used to improve the ISAR algorithms providing the radar imaging of aerial vehicles.

Published: July 2019

Current technological development changes the people's lifestyle becoming progressively modern. Technological development encourages the rapid digitalization that occurs in all countries. The incapability of a country to meet domestic demand for digital products that are closely related to high technology content drives the import of high technology products. On the other hand, the development of Foreign Direct Investment (FDI) is essential in order to support the development of domestic technology of a country due to its spillover effects. ASEAN 6 is a highly attractive for foreign investors as it has strategic location, large market share and abundant resources. This study examines the influence of FDI and innovation on imported high technology products in ASEAN 6. This research employed the panel data analysis from six ASEAN countries during the period of 2007 to 2016. The results of this study indicated that FDI and innovation have a positive effect on imports of high products technology in ASEAN 6.
