Authors: Mamilla Divya , Araque Katherine , Brofferio Alessandra , Gonzales Melissa , Sullivan James , Nilubol Naris , Pacak Karel
Published: July 2019

Pheochromocytomas and paragangliomas (PPGLs) are rare catecholamine-secreting neuroendocrine tumors of the adrenal medulla and sympathetic/parasympathetic ganglion cells, respectively. Excessive release of catecholamines leads to episodic symptoms and signs of PPGL, which include hypertension, headache, palpitations, and diaphoresis. Intraoperatively, large amounts of catecholamines are released into the bloodstream through handling and manipulation of the tumor(s). In contrast, there could also be an abrupt decline in catecholamine levels after tumor resection. Because of such binary manifestations of PPGL, patients may develop perplexing and substantially devastating cardiovascular complications during the perioperative period. These complications include hypertension, hypotension, arrhythmias, myocardial infarction, heart failure, and cerebrovascular accident. Other complications seen in the postoperative period include fever, hypoglycemia, cortisol deficiency, urinary retention, etc. In the interest of safe patient care, such emergencies require precise diagnosis and treatment. Surgeons, anesthesiologists, and intensivists must be aware of the clinical manifestations and complications associated with a sudden increase or decrease in catecholamine levels and should work closely together to be able to provide appropriate management to minimize morbidity and mortality associated with PPGLs.
Rediscovering the Idea of Cultural Heritage and the Relationship with Nature: Four Schools of Essential Thought of the Ancient Han Chinese
Authors: Chen Otto , Han Dawei
Published: July 2019

After a long-standing debate of pluralism in heritage conservation, the global practice has just started to broaden its view from material to people and even to nature, leading to the potential of a more comprehensive understanding and harmony between these spheres. Notwithstanding that the shift from material to people and then to nature seemingly looks like the only path in the modern heritage conservation movement to achieve the foregoing goals, in fact, there exist some regional cultures that originally featured particular views on human–nature harmony. This paper hence highlights the regional difference in heritage with a focus on China of ancient times, which unfolds the particular perspective emphasising the unity of human and nature. With a case study of Huaqing Palace of the Tang Dynasty (618–907 CE), the research is expected to be the first attempt to rediscover that the four schools of thought, Buddhism, Taoism, Confucianism and I Ching, had jointly formed a “wisdom” system of the ancient Han Chinese in shaping the idea of cultural heritage, as well as the idea of heritage conservation, which were inherited by modern Chinese without knowing and recognising it. The paper, therefore, argues that without understanding and acknowledging the significance of the ancient Han Chinese’s particular view on nature and the universe formed by the four schools of thought behind the material, it is not likely to protect and promote comprehensively their heritage value, such that the importance of cultural diversity will be just rhetoric.

Published: July 2019

Disparities in healthy food access are well documented in cross-sectional studies in communities across the United States. However, longitudinal studies examining changes in food environments within various neighborhood contexts are scarce. In a sample of 142 census tracts in four low-income, high-minority cities in New Jersey, United States, we examined the availability of different types of food stores by census tract characteristics over time (2009–2017). Outlets were classified as supermarkets, small grocery stores, convenience stores, and pharmacies using multiple sources of data and a rigorous protocol. Census tracts were categorized by median household income and race/ethnicity of the population each year. Significant declines were observed in convenience store prevalence in lower- and medium-income and majority black tracts (p for trend: 0.004, 0.031, and 0.006 respectively), while a slight increase was observed in the prevalence of supermarkets in medium-income tracts (p for trend: 0.059). The decline in prevalence of convenience stores in lower-income and minority neighborhoods is likely attributable to declining incomes in these already poor communities. Compared to non-Hispanic neighborhoods, Hispanic communities had a higher prevalence of small groceries and convenience stores. This higher prevalence of smaller stores, coupled with shopping practices of Hispanic consumers, suggests that efforts to upgrade smaller stores in Hispanic communities may be more sustainable.

Published: July 2019

The present study deals with the fabrication of epoxy composites reinforced with 50 wt% of date palm leaf sheath (G), palm tree trunk (L), fruit bunch stalk (AA), and leaf stalk (A) as filler by the hand lay-up technique. The developed composites were characterized and compared in terms of mechanical, physical and morphological properties. Mechanical tests revealed that the addition of AA improves tensile (20.60–40.12 MPa), impact strength (45.71–99.45 J/m), flexural strength (32.11–110.16 MPa) and density (1.13–1.90 g/cm3). The water absorption and thickness swelling values observed in this study were higher for AA/epoxy composite, revealing its higher cellulosic content, compared to the other composite materials. The examination of fiber pull-out, matrix cracks, and fiber dislocations in the microstructure and fractured surface morphology of the developed materials confirmed the trends for mechanical properties. Overall, from results analysis it can be concluded that reinforcing epoxy matrix with AA filler effectively improves the properties of the developed composite materials. Thus, date palm fruit bunch stalk filler might be considered as a sustainable and green promising reinforcing material similarly to other natural fibers and can be used for diverse commercial, structural, and nonstructural applications requiring high mechanical resistance.
Laboratory-Based Investigation into Stress Corrosion Cracking of Cable Bolts
Authors: Wu Saisai , Guo Jinping , Shi Guangbin , Li Junping , Lu Caiwu
Published: July 2019

Cable-bolt failures due to stress corrosion cracking (SCC) could significantly compromise the sustainability and long-term stability of underground constructions. To fully understand the SCC of cable bolts, a two-step methodology was implemented: (i) long-term cable-bolt coupon tests using mineralogical materials collected from underground mines; and (ii) accelerated full-scale cable-bolt tests using an acidified solution. In the long-term tests, a novel three-point bending coupon was designed. The effects of mineralogical materials on SCC were evaluated under the simulated underground bolting conditions through the application of “corrosion cells”. For accelerated tests, SCC resistance of different type of cable bolts was examined using the new designed tensile-loading apparatus under the periodically increasing strain-rate loading mechanism. It was identified that mineralogical materials and applied stress intensity accelerated the corrosion process of the cable bolts. The number of wires and wire surface conditions in different types of cable bolt directly affected SCC susceptibility. The cable bolts with a greater number of wires provided higher resistance to SCC. The developed experimental methodologies can be applied to study SCC in other reinforcement materials and the results can be used to design optimal support systems in different environmental and geotechnical conditions.
“I’ve Only Just Heard About It”: Complementary and Alternative Medicine Knowledge and Educational Needs of Clinical Psychologists in Indonesia
Authors: Liem Andrian
Published: July 2019

Background and objectives: The inadequate knowledge of complementary and alternative medicine (CAM) among health professionals may put their clients at risk because clients would then find information about CAM from unreliable sources. Clinical psychologists (CPs), as health professionals, also have the opportunity to provide psychoeducation on the latest scientific CAM research for their clients. The current study aimed to explore knowledge and educational needs regarding CAM among CPs in Indonesia because previous studies on exploring CAM knowledge and educational needs regarding CAM were primarily conducted in Western countries. Materials and Methods: Data were collected through semi-structured face-to-face interviews with 43 CPs in public health centers (PHCs) in Indonesia. Most interviews were conducted at the PHCs where the participants worked and lasted for 55 minutes on average. The interview recordings were transcribed and were analyzed using deductive thematic analysis. Results: Five main themes emerged within participants’ responses regarding CAM knowledge and educational needs. First (CAM understanding), participants’ responses ranged from those with little or no prior knowledge of CAM treatments and uses, to those with much greater familiarity. Second (source of knowledge), participants’ access ranged widely in terms of references, from popular to scientific literature. Third (why is it important?), participants identified CAM as an essential part of Indonesian culture and considered it therefore crucial to have this cultural knowledge. Fourth (the challenges and what is needed?), the challenges for improving participants’ knowledge came from personal and institutional levels. Fifth (what and how to learn?), participants advised that only CAM treatments that fit in brief psychotherapy sessions should be introduced in professional training. Conclusions: This qualitative study discovered that CAM was neither well-known nor understood widely. Participants advised that professional associations and health institutions should work together in enhancing knowledge of CAM and incorporating CAM education into psychology education.

Published: July 2019

Metal–organic frameworks (MOFs), as a class of crystalline hybrid architectures, consist of metal ions and organic ligands and have displayed great potential in luminescent sensing applications due to their tunable structures and unique photophysical properties. Until now, many studies have been reported on the development of MOF-based luminescent sensors, which can be classified into two major categories: MOF chemosensors based on reversible host–guest interactions and MOF chemodosimeters based on the irreversible reactions between targets with a probe. In this review, we summarize the recently developed luminescent MOF-based chemodosimeters for various analytes, including H2S, HClO, biothiols, fluoride ions, redox-active biomolecules, Hg2+, and CN−. In addition, some remaining challenges and future perspectives in this area are also discussed.

Published: July 2019

Inhibition of intestinal glucose resorption can serve as an effective strategy for the prevention of an increase in blood glucose levels. We have recently shown that various extracts prepared from guava (Psidium guajava) inhibit sodium-dependent glucose cotransporter 1 (SGLT1)- and glucose transporter 2 (GLUT2)-mediated glucose transport in vitro (Caco-2 cells) and in vivo (C57BL/6N mice). However, the efficacy in humans remains to be confirmed. For this purpose, we conducted a parallelized, randomized clinical study with young healthy adults. Thirty-one volunteers performed an oral glucose tolerance test (OGTT) in which the control group received a glucose solution and the intervention group received a glucose solution containing a guava fruit extract prepared by supercritical CO2 extraction. The exact same extract was used for our previous in vitro and in vivo experiments. Blood samples were collected prior to and up to two hours after glucose consumption to quantitate blood glucose and insulin levels. Our results show that, in comparison to the control group, consumption of guava fruit extract resulted in a significantly reduced increase in postprandial glucose response over the basal fasting plasma glucose levels after 30 min (Δ control 2.60 ± 1.09 mmol/L versus Δ intervention 1.96 ± 0.96 mmol/L; p = 0.039) and 90 min (Δ control 0.44 ± 0.74 mmol/L versus Δ intervention −0.18 ± 0.88 mmol/L; p = 0.023). In addition, we observed a slightly reduced, but non-significant insulin secretion (Δ control 353.82 ± 183.31 pmol/L versus Δ intervention 288.43 ± 126.19 pmol/L, p = 0.302). Interestingly, storage time and repeated freeze-thawing operations appeared to negatively influence the efficacy of the applied extract. Several analytical methods (HPLC-MS, GC-MS, and NMR) were applied to identify putative bioactive compounds in the CO2 extract used. We could assign several substances at relevant concentrations including kojic acid (0.33 mg/mL) and 5-hydroxymethylfurfural (2.76 mg/mL). Taken together, this clinical trial and previous in vitro and in vivo experiments confirm the efficacy of our guava fruit extract in inhibiting intestinal glucose resorption, possibly in combination with reduced insulin secretion. Based on these findings, the development of food supplements or functional foods containing this extract appears promising for patients with diabetes and for the prevention of insulin resistance.

Published: July 2019

The effects of the fluorinated monomer with an ethynyl group on the electro-optical properties of polymer-stabilized blue phase liquid crystals (PSBPLCs) were investigated in different polymer systems. In rigid polymer systems, the Kerr constant can be increased by about 27.6%, while keeping a microsecond response time. In soft polymer systems, hysteresis decreased by about 45.5% and residual birefringence can be reduced from 1.85% to 0.6%. The above phenomena exhibited dual functions of affecting the anchoring energy and the viscosity of the system simultaneously. The results provide a potential value for the ethynyl-containing monomers in PSBPLC systems.

Authors: Marega Carla , Malizia Federica , Spataro Stefano
Published: July 2019

Samples of random poly(butene-ran-ethylene) copolymers produced with metallocene catalysts were studied in order to elucidate the different behaviors of this particular class of materials as a function of increasing ethylene (C2) content. The samples cooled down from the melt are semi-crystalline or amorphous and crystallize in different crystal modifications, depending on the amount of C2. Thermal analysis, X-ray diffraction, and microscopic techniques were used to follow the changes of the materials with aging time and to understand the structural and morphological behavior with the aim of highlighting possible peculiar properties, which may be of great interest in the application of such materials in the field of Hot Melt adhesives.

Authors: Liu Chenchen , Liu Shuning , Lin Jian , Wang Lingling , Huang Yumin , Liu Xiaobo
Published: July 2019

Poly(arylene ether nitrile)s with sulfonic and carboxylic groups (SCPEN) were synthesized to investigate their electrical properties. This new series of copolymers were prepared by copolymerization of phenolphthalein, potassium hydroquinonesulfonate, and 2,6-difluorobenzonitrile, in different mole ratios. Their thermal, mechanical and dielectric properties were investigated in detail. By adjusting the composition of sulfonic and carboxylic groups, it can be concluded that the dielectric constant increases with the increase of sulfonic groups, and mechanical and thermal properties improve with the increase of carboxylic groups. The as-prepared SCPEN films show potential applications in electronic storage materials, which provide insights into the correlation of SCPEN electrical properties with its chemical structure. The structure–property relationship is established to broaden the application of functionalized PEN. Furthermore, SCPEN with rich polar groups may also be used as the polymer matrix to increase the interaction with the filler surface, ensuring a better dispersion of filler in the matrix. This provides a reference for the development of high dielectric materials.
A Review of Circular Economy Development Models in China, Germany and Japan
Authors: Ogunmakinde Olabode Emmanuel
Published: July 2019

The circular economy (CE) concept is gaining traction as a sustainable strategy for reducing waste and enhancing resource efficiency. This concept has been adopted in some countries such as Denmark, Netherlands, Scotland, Sweden, Japan, China, and Germany while it is being considered by others including England, Austria, and Finland. The CE has been employed in the manufacturing, agricultural, textile, and steel industries but its implementation varies. It is against this backdrop that this study seeks to identify CE implementation in three pioneering countries (China, Japan, and Germany). A critical review and analysis of the literature was conducted. The results revealed enabling and core policies/laws for the development of the CE concept. It also identified the implementation structure of the CE in China, Germany, and Japan. In conclusion, the findings of this study are expected to serve as a guide for developing and implementing the CE concept in various sectors of the economy.
An Optimal Decision-Tree Design Strategy and Its Application to Sea Ice Classification from SAR Imagery
Authors: Lohse Johannes , Doulgeris Anthony P. , Dierking Wolfgang
Published: July 2019

We introduce the fully automatic design of a numerically optimized decision-tree algorithm and demonstrate its application to sea ice classification from SAR data. In the decision tree, an initial multi-class classification problem is split up into a sequence of binary problems. Each branch of the tree separates one single class from all other remaining classes, using a class-specific selected feature set. We optimize the order of classification steps and the feature sets by combining classification accuracy and sequential search algorithms, looping over all remaining features in each branch. The proposed strategy can be adapted to different types of classifiers and measures for the class separability. In this study, we use a Bayesian classifier with non-parametric kernel density estimation of the probability density functions. We test our algorithm on simulated data as well as airborne and spaceborne SAR data over sea ice. For the simulated cases, average per-class classification accuracy is improved between 0.5% and 4% compared to traditional all-at-once classification. Classification accuracy for the airborne and spaceborne SAR datasets was improved by 2.5% and 1%, respectively. In all cases, individual classes can show larger improvements up to 8%. Furthermore, the selection of individual feature sets for each single class can provide additional insights into physical interpretation of different features. The improvement in classification results comes at the cost of longer computation time, in particular during the design and training stage. The final choice of the optimal algorithm therefore depends on time constraints and application purpose.
Managing the Introduction of Circular Products: Evidence from the Beverage Industry
Authors: Urbinati Andrea , Chiaroni Davide , Toletti Giovanni
Published: July 2019

The aim of this paper is to study what managerial practices companies follow and implement in their business model to manage the introduction of Circular Products. Extensively screening extant literature in the field, we clustered a set of relevant managerial practices in four main principles of Circular Economy (CE) adoption at the product level: (i) Energy efficiency and usage of renewable sources of energy; (ii) Product and process optimisation for resource efficiency; (iii) Product design for circularity; (iv) Exploitation of waste as a resource. Then, the adoption of these principles was tested on two companies (and three Circular Products) operating in the beverage-packaging industry, where the adoption of CE is further challenged by the fact that packaging is necessary to deliver the product to consumers, but the majority of the one-way packaging is discarded after use. The identified principles provide general objectives in terms of end goals that should be achieved in order to adopt CE and manage the introduction of Circular Products. This paper shows a practical implementation of these principles on real empirical cases for theory-testing scopes.
The Mediating Effect of Decision Quality on Knowledge Management and Firm Performance for Chinese Entrepreneurs: An Empirical Study
Authors: Yu Haiyun , Shang Yanjie , Wang Nan , Ma Zhenzhong
Published: July 2019

While it is well-known knowledge management is crucial for an organization’s competitive advantage, relatively little research has explored the process whereby knowledge management affects firm performance in a collectivistic culture such as China. This study is to explore the mechanism through which knowledge management helps improve firm performance and then to examine the mediating role of decision quality in the Chinese context. Using a self-administered questionnaire to collect data from Chinese entrepreneurs and with structural equation modeling, this study shows that knowledge accumulation, internal sharing, and external knowledge sharing all have a positive impact on firm performance, and decision quality partially mediates the impact of knowledge management on firm performance. This study adds value to the knowledge management literature by introducing decision quality as a mediating variable to examine the impact of knowledge sharing on firm performance in China. The findings of this study can help enrich the literature on knowledge management and firm performance and highlight the important impact of decision quality on knowledge management and firm performance. Management practitioners can also benefit from the findings.

Published: July 2019

In the near future, symmetry technologies for the Internet of Things (IoT), along with symmetry and asymmetry applications for IoT security and privacy, will re-design the socio-ecological human terrain morphology. The IoT ecosystem deploys diverse sensor platforms connecting billions of heterogeneous objects through the Internet. Most sensors are low-energy consuming devices which are designed to transmit sporadically or continuously. However, when we consider the billions/trillions of connected sensors powering various user applications, their energy efficiency (EE) becomes a critical issue. Therefore, the importance of EE in IoT technology cannot be overemphasised, specifically the development of EE solutions for sustainable IoT technology. Propelled by this need, EE proposals are expected to address IoT’s EE issues. Consequently, many developments have been displayed, and highlighting them to provide clear insights into eco-sustainable and green IoT technologies is becoming a crucial task. To pursue a clear vision of green IoT, this article aims to describe the current state-of-the art insights into energy-saving practices and strategies on green IoT. The major contribution of this study is the review and discussion of the substantial issues enabling hardware green IoT to focus on green wireless sensor networks and green radio-frequency identification. This review paper will contribute significantly to the future implementation of green and eco-sustainable IoT.
A Multi-Dimension Spatial Method for Topology Awareness and Multipath Generating
Authors: Guan Yunchong , Lei Weimin , Zhang Wei , Zhan Yuzhuo , Li Hao , Zhang Songyang
Published: July 2019

Multipath diversity significantly impacts multipath transmission quality. Enough multipath diversity would minimize the negative influence brought by an individual path, thus improving tolerance capability of network congestion and failure. However, multipath diversity is hard to guarantee on overlay networks because of inaccurate awareness of underlay network and multipath generating methods considering little about underlay diversity. In this paper, we design a multi-dimension spatial method for topology awareness and multipath generating. Analyzing that the complicated underlay networks with multiple autonomous systems reduce the accuracy of network positioning for topology awareness, we decompose the underlay networks into multiple dimensions, namely intra and inter autonomous system dimensions. We generate independent views for each autonomous system and merge views by embedding exchange points. Then, we design some spatial mechanisms to evaluate link diversity and to constrain multipath generating. Based on the multi-dimensional view, multipath generating is conducted in inter and intra autonomous system phases. Experiments demonstrate that the proposed method improves topology awareness accuracy and guarantees multipath diversity better and the transmission quality is improved.

Authors: Ma Zhiteng , Yuan Xianfeng , Han Sen , Sun Deyu , Ma Yan
Published: July 2019

As a global-optimized and naturally inspired algorithm, particle swarm optimization (PSO) is characterized by its high quality and easy application in practical optimization problems. However, PSO has some obvious drawbacks, such as early convergence and slow convergence speed. Therefore, we introduced some appropriate improvements to PSO and proposed a novel chaotic PSO variant with arctangent acceleration coefficient (CPSO-AT). A total of 10 numerical optimization functions were employed to test the performance of the proposed CPSO-AT algorithm. Extensive contrast experiments were conducted to verify the effectiveness of the proposed methodology. The experimental results showed that the proposed CPSO-AT algorithm converges quickly and has better stability in numerical optimization problems compared with other PSO variants and other kinds of well-known optimal algorithms.

Marine Morbilliviruses: Diversity and Interaction with Signaling Lymphocyte Activation Molecules
Authors: Ohishi Kazue , Maruyama Tadashi , Seki Fumio , Takeda Makoto
Published: July 2019

Epidemiological reports of phocine distemper virus (PDV) and cetacean morbillivirus (CeMV) have accumulated since their discovery nearly 30 years ago. In this review, we focus on the interaction between these marine morbilliviruses and their major cellular receptor, the signaling lymphocyte activation molecule (SLAM). The three-dimensional crystal structure and homology models of SLAMs have demonstrated that 35 residues are important for binding to the morbillivirus hemagglutinin (H) protein and contribute to viral tropism. These 35 residues are essentially conserved among pinnipeds and highly conserved among the Caniformia, suggesting that PDV can infect these animals, but are less conserved among cetaceans. Because CeMV can infect various cetacean species, including toothed and baleen whales, the CeMV-H protein is postulated to have broader specificity to accommodate more divergent SLAM interfaces and may enable the virus to infect seals. In silico analysis of viral H protein and SLAM indicates that each residue of the H protein interacts with multiple residues of SLAM and vice versa. The integration of epidemiological, virological, structural, and computational studies should provide deeper insight into host specificity and switching of marine morbilliviruses.

Authors: Fu Rebecca Menhua , Decker Charlotte Caroline , Dao Thi Viet Loan
Published: July 2019

Despite a growing awareness, hepatitis E virus (HEV) remains understudied and investigations have been historically hampered by the absence of efficient cell culture systems. As a result, the pathogenesis of HEV infection and basic steps of the HEV life cycle are poorly understood. Major efforts have recently been made through the development of HEV infectious clones and cellular systems that significantly advanced HEV research. Here, we summarize these systems, discussing their advantages and disadvantages for HEV studies. We further capitalize on the need for HEV-permissive polarized cell models to better recapitulate the entire HEV life cycle and transmission.
Training primary care providers in opioid deprescribing and chronic pain management based on local guidance: a pre–post study of attitude change
Authors: White Ruth , Hayes Chris , Boyes Allison W , Fitzgerald Sandra , Rajappa Hema , Paul Christine L
Published: July 2019

Background. Local chronic non-cancer pain guidance recommends that general practitioners should consider opioid deprescribing and referral to multidisciplinary healthcare providers for behaviourally based treatments. We designed a training package called AIMM (Assess, Inform, Manage and Monitor) to reinforce this stewardship.Aim. To identify whether participation in AIMM training effectively aligned clinicians’ attitudes with local guidance for treating chronic non-cancer pain.Design and setting. In 2014–15, the AIMM training was tested using a pre–post-test non-randomised design at two sites in NSW, Australia. The primary outcome measure was an 11-item, study-specific, pain attitude questionnaire (PAQ).Method. Step one of AIMM training involved online completion of the PAQ and review of a specialist pain website. Step two involved attendance at two face-to-face, two-hour interactive workshops led by pain experts who addressed opioid deprescribing and switching to broader care. A repeat PAQ survey was completed at the conclusion of the second workshop.Results. Nineteen participants attended the workshops, including general practitioners (n = 7), nurses (n = 5), exercise physiologists (n = 2), a dietitian (n = 1), community pharmacists (n = 2) and psychologists (n = 2). Significant shifts in six attitudes occurred, including prescribing less pain medication, greater emphasis on social reconnection, increasing planned activity and adopting anti-inflammatory nutrition (p < .05). Responses to the item regarding expectations of a positive recovery was not aligned with local guidance and no significant attitudinal change was found. Four other attitudes were aligned with local guidance at baseline and did not change during the study.Conclusions. Online information and face-to-face training can achieve a change in healthcare provider attitudes towards non-pharmacological treatment of chronic non-cancer pain. Further work is needed to assess whether attitudinal changes are maintained and translate into behavioural change.
On the identity of socialism in modern China
Authors: Lyubinin A.B.
Published: July 2019

The article comments on the concept of «socialism with Chinese specificity», which forms the ideological basis of the «Chinese miracle». The ideological origins of this concept, starting with Confucianism, are revealed. It has evolved to become increasingly pragmatic and to adapt to the realities of national and global development. The relation of this concept with the Marxist concept of socialism is shown. The article substantiates the fundamental theoretical thesis that in the objective-essential sense (in the elimination of, in particular, national specifics) Chinese society is a transitional form to socialism (a certain analogue of the Soviet society of the NEP period). The author talks about a «heterogeneous», «mixed» socio-economic system, the vector and nature of the future evolution of which will depend crucially on the strategic course of the CPC.
The Impossible Trinity» rule in the context of international experience

Published: July 2019

The article is devoted to the «Trilemma» of the policy of the monetary authorities, or the «rule of impossible trinity». This policy compatibility rule, formulated more than 50 years ago, remains relevant today. Its reliability is generally confirmed by a number of empirical studies, although there are also suggestions on the need to adjust this economic and theoretical development. The corresponding discussion also affects the policy of the Bank of Russia (mega-regulator), which carries out inflation targeting in conditions of the free movement of cross-border capital and the use of a floating ruble exchange rate. Regarding the effectiveness of this policy, carried out in the presence of increased sensitivity of the Russian economy to external shocks, the authors express certain doubts.

ABSTRACT: Mobilization is a nursing intervention that is important for postoperative patients. Mobilization has the benefit of accelerating postoperative recovery and healing. High self-efficacy in patients for early postoperative mobilization is very necessary because of the many obstacles to mobilization in postoperative patients. The purpose is to describe the self efficacy of postoperative patient mobilization. The study design was a descriptive study, with a sample of 75 patients taken by purposive sampling. The variable measured in this study is the mobilization self-efficacy variable. The instrument used is an instrument of mobilization self-efficacy. The results showed that only a small proportion (17%) of postoperative patients had high self efficacy. Further research is needed on the influencing factors and appropriate nursing interventions to improve the self efficacy of patient mobilization.

ABSTRACT : In the adolescence, self-esteem is a key to success in life. A positive self esteem can evoke self confidence. Self-esteem in adolescence is very vulnerable to be disturbed. So teenagers are at risk of going low self-esteem. The results of the study of MAN I school in West Bogor showed that 61.53% of teenagers have low self-esteem. The purpose of this study is to determine the effect of selfawareness exercises and cognitive therapy to the adolescent self-esteem. The benefits of this research is to enhance the development of school health nursing programs, especially in self-awareness exercise intervention and cognitive therapy to improve adolescent self-esteem. The design of this study is a Quasi-Experimental Research involving pre and post tests with control group. The number of respondents were 148, consist of 74 adolescents in the intervention group, and another 74 adolescents in the control group. The sampling is done by multi-stage random sampling. The results showed a high significant differences exist between self-esteem of teenagers before intervention with adolescent selfesteem after intervention and cognitive therapy. While in the control group there was no difference. There are differences in adolescent self-esteem in the intervention group and the control group at posttes. From this result, it can be concluded that the exercise of self-awareness and cognitive therapy can improve the self-estem of adolescent.

Relationship of the employment policy with rural development in the European Union
Authors: Béresné Mártha Bernadett
Published: July 2019

Employment policy has won primary attention both at national and EU levels for the past decade. Managing its problems has become one of the major social economic and political challenges. One of the problems is the aging of the continent’s population, which is in close relation with the slow increasing or decreasing economic trends.Comparing the EU’s unemployment, employment and labour productivity rates to those of ten years earlier a positive tendency can be traced. On of the other hand compared with the USA, Japan or the average of OECD countries the Community has still not been able to reduce its several decades lasting leeway. Difficulties of labour management are much more striking in rural territories than in urban districts. Not even the second pillar of the Common Agricultural Policy: the rural development has been successful in managing the employment of the labour supersededfrom the primer sector so far, which is significantly reflected in the unfavourable indicators of labour management and unemployment.

Published: July 2019

After the EU-accession we should have a definite idea about what kind of production structure and land use should Hungary obtain to meet the conditions undertaken in the different governmental decisions. In the course of Hungarian land use, significant changes have taken place in the last eighty years. Further changes are influenced by the fact that according to various decisions, legislative provisions and ideas in a short time the energy orchards’ domiciliation could start in large. For this, financial support can be required from EU-sources. As for the woody energy plants, subsidies can be required for the domiciliation and as for herbaceous plants grants can be required for growing. As far as the latter is concerned, the subsidy will be around 26-27 thousand Ft/hectares according to the plans. However, the cultivation method does not have to be changed toswitch from plow-land to energy plants. The question is if the produced commodity will be received by power plants and if it ensures appropriate income for the farmer. In my research I wanted to find from the given woody energy plants which are those that are the most profitable.

I introduce the performance management from the area of human resource management that I examined at organizations operating in market environment and in the public sphere as well. The reason of my choice of subject is that the performance management got into the centre of interest also in Hungary lately.The scale of values connecting traditionally to the organizations of the private and public sphere is different vitally, what affected substantive differences of the organization, the management and the human resources management environment. Within these I tried to reveal their performance management system and with their comparison to draw conclusions. I did my surveys at profit oriented organizations and at organizations operating at the public sphere.Performance management is one centre field of modern human resource managing, as the basis of the successful functioning of any company is the possibly most effective operation of its resources. Performance management is a possibility for the company and for the employer to overview the realization of the determined aims and the factors that block or promote accomplishments. Considering the results, the employee and the manager could determine subsequent realistic and accessible aims for the following period. Achievement management is extremelyimportant in those positions where achievement could not be measured accurately.I carried out my surveys according to performance management by observation and data acquisition. I applied questionnaire survey to collect data, or rather made deep interviews; I talked personally with more employees as well.The questionnaire consisted of one data format and performance management questionnaire. I processed the gathered data by computer and visualized graphically. I also did examinations by using statistic methods, by which I was able to get to know the certain organizations deeper and thus it was possible for me to reveal more connections.
Assessing of soil aggregate stability: the sand-correction and its relevance
Authors: Huisz Andrea
Published: July 2019

Soil structure and changes in its quality caused by Maize stem (1), Wheat straw (2) and Maize stem & wheat straw (3) addition were assessed by three aggregate-stability indices. We observed that the NSI index formula proposed by Six et al. (2000) was nonsensitive to the changes in soil structure caused by the investigated organic matter addition. Furthermore it overestimates the aggregate-stability of the investigated silty sandy loam soil. Therefore we proposed a new modified NSI formula which is sensitive to the questionable treatments and that resulted in a morerealistic NSI data. The most sensitive index to differences of the investigated treatments were the Mean weight diameter (MWD) proposed by van Bavel (1953, in Kemper és Rosneau, 1986).

We carried out phylogenetic study analyzing sequences of genetic markers in the taxonomy of Phoma and Phoma-like fungi. Different species of Phoma and Phoma-like fungi occurring on soybean (Phoma pinodella, Phoma sojicola, Phyllosticta sojicola, Phoma exigua var. exigua) are difficult to identy because of their high morphological and symptomatic similarities.Twenty-two isolates of nine different Phoma species were obtained from reference culture collections. Seven of them were isolated from soybean, the others were collected from different hosts.The Phoma isolates were firstly characterised by morphologically, and then we employed a part of the gene responsible for the synthesis of translation elongation factor 1 subunit alpha protein (tef1), ITS region, as well as β-tubulin partial sequences as potential genetic markers to inferphylogenetic relationships among different Phoma species..Finally, their ITS and tef1 sequences were sequenced and analysed by Bayesian approaches.According to phylogenetic trees inferred by Bayesian analysis of tef1, ITS and β-tubulin sequences, different Phoma species can be separated proving that these phylogenetic markers are well suited for phylogenetic studies of Phoma species. However, the phylogenetic tree does not support the traditional Phoma sections based on morphological characterization.Bayesian analyses of the three sequences confirmed that the Phyllosticta sojicola species is clustered with the Phoma exigua var. exigua group and the Phoma sojicola is grouped with Phoma pinodella group. The molecular data provide evidence for reclassification of formerly mentioned soybean pathogens.
The examination of relation between the C/N ratio and the biogas yields in the Regional Biogas Plant of Nyírbátor

Published: July 2019

The Regional Biogas Plant of Nyírbátor was built by the Bátortrade Ltd. The biogas plant contains 6 mezophil and 6 thermophil fermentation tanks, because the biogas production is based on mixed compositions. The regional plant is a multifunctional system. It produces agricultural products and biogas with high methane content. The utilization of biogas is also accomplished here; gas-engines transform it to electricity andheat-energy. The product electricity is used by the local plants, the surplus is sold. The aim of the research is the examination of the quality and quantity of the input materials that put into the mixers and follow the seasonal, periodical and optional changes of the input materials. The analyzation of the quality and quantity data can give an answer to the optional changes of biogas production because the input materials determine the composition of the examined recipe. The C/N ratio was between 11-13, the maximal value of the biogas yield was observed by 12.35 C/N ratio.
The European Research Area: in quest of the Lisbon goals
Authors: Mikita József
Published: July 2019

strong educational and scientific knowledge basie is one of Europe's traditional key assets that has made it possible for our continent to become world class in several research fields. Despite these great achievements, the position of the European research and technological development (RTD) potential is currently being challenged by a rapidly changing global competition, including the two main rivals, the US and Japan. The European Union (EU) is behind these countries as regards research and innovation output. Moreover, European research is faced with theimplications of globalisation of markets and industries, digitalisation and new technologies, as well as a need to address societal issues such as an ageing population or climate change.At the same time, the European Union (EU) is facing the uneven distribution of RTD capacities and excellence within its own borders, especially the EU12 countries are lagging behind in thisrespect.In order to meet this twofold challenge the EU has to step up its efforts for the creation of a legitimate "European Research Area" that will make the EU more competitive on the international scene, and also encourage the less developed EU member states to invest more and better into research and innovation.
