Published: November 2018

Окреслено основні вектори щодо розуміння сутності диференціації оплати праці як соціальної детермінанти в механізмі організації оплати праці. Визначено і охарактеризовано основні соціально-економічно-нормативні чинники впливу на процес індивідуалізації заробітної плати. Запропоновано систематизацію чинників, які охоплюють базові вектори визначення сутності індивідуалізації оплати праці: соціальний вектор (ринок праці як регулятор основних тенденцій зайнятості працездатного населення, державне регулювання у сфері соціальних гарантій, відповідність оплати праці залежно від ступеня володіння професійними компетентностями), економічний вектор (підвищення рівня ефективності господарської діяльності як резервів для фінансового забезпечення індивідуалізації оплати праці, підвищення рівня ефективності праці суб’єктів трудових відносин), нормативний вектор (посилення соціального і правового захисту громадян України, які працюють за кордоном, забезпечення нормативно-правовими засадами рівних умов оплати праці в різних секторах економіки).На основі цього запропоновано модель пошуку резервів фінансового забезпечення цього процесу задля прискорення соціального й економічного розвитку національного господарства в цілому, яка обґрунтовується за допомогою інструментів кореляційно-регресійного аналізу. Інтерпретація результатів проведеного дослідження надала можливість охарактеризувати основні напрями, які дозволяють визначити чинники впливу на формування фінансового забезпечення індивідуалізації рівня оплати у праці, це збільшення фонду робочого часу і зменшення кількості працівників, яким нарахована зарплата в межах мінімальної зарплати.

Published: November 2018

The paper is devoted to the problem of preventing financial crises in corporate systems, whose activities are becoming more and more complex in the context of globalization. The mechanism of early informing and crisis prevention in corporate systems is proposed, and includes five main modules: an analysis of the financial condition of the corporation, an analysis of the financial condition of subsidiaries, an evaluation of the impact of the financial crisis on a subsidiary on the threat of bankruptcy of the corporation as a whole, forecasting the financial condition of subsidiaries and corporation as a whole, anti-crisis management. The first four modules of the mechanism are the modules of implementation of proactive crisis management in the corporation, aimed at preventing the emergence of a crisis state, both in individual elements and in the corporate system as a whole. The fifth module is used in conditions of the current negative estimation of the financial condition of the corporation, and it is a "response" to existing crisis processes and phenomena in the corporation. After its implementation during the process of monitoring of the financial condition, proactive control modules are started to be used to allow early diagnosis and to prevent a crisis state. Particular attention is paid to such modules of proactive management as the evaluation of the impact of financial crises of subsidiaries on bankruptcy of the corporations as a whole and forecasting financial crises. A model basis for these two modules was developed. Neural networks, the mathematical apparatus of fuzzy logic, and the Caterpillar method were used for developing the models of estimation of the crisis threat in the corporate system. The developed set of models allowed to estimate the threat of financial crises in the parent enterprise and in the subsidiaries of the corporation, not only in the current but also in the perspective periods. The obtained results indicate that the financial condition of the investigated corporation is characterized by low level of the bankruptcy threat. Along with this, there is an increase in the threat of bankruptcy in a number of subsidiaries in the perspective period and the strong impact of local crises on the financial position of the corporation as a whole. The latter leads to the need of implementation of the anti-crisis measures in the corporate structure. An adequate tool for choosing anti-crisis measures and developing scenarios for the implementation of the anti-crisis management strategy is simulation modelling based on the concept of system dynamics.

Проаналізовані окремі економічні характеристики юридичної особи. Досліджено питання власності як передумови виникнення та функціонування юридичної особи, відділення майна через конструкцію юридичної особи як економічний спосіб ухилення від відповідальності її учасників та вивчення юридичної особи як системи контрактів. Виділено фактори, що зумовлюють економічну складову юридичної особи: відносини власності як передумова виникнення та функціонування юридичної особи; відділення майна через конструкцію юридичної особи як економічний спосіб ухилення від відповідальності її учасників; юридична особа як система контрактів.Зроблено висновки, що: власність у рамках юридичної особи як економічна категорія виконує певну функцію, яка полягає у формуванні значного за обсягом капіталу на найвигідніших для всіх осіб, втягнутих у цей процес, умовах з метою максимально прибуткового його використання; виходячи з економічної складової, можна стверджувати, що юридична особа є виключно інструментом відокремлення майна, що здійснюється з метою обмеження ризику його втрати у процесі певної діяльності реальної (фізичної) особи; юридичну особу з економічного погляду можна розуміти як систему контрактів, що зумовлено взаємозв’язками між її засновниками (учасниками), особами, які нею управляють (менеджерами), і самою юридичною особою.

Важливою проблемою нинішнього етапу розвитку аграрної економіки України є наявність виробничого потенціалу сільськогосподарських підприємств, необхідного для виробництва визначених державними програмами та господарськими бізнес-планами обсягів агропродовольчої продукції. Це викликає потребу відповідних досліджень у питанні оцінки виробничого потенціалу сільськогосподарських підприємств з позиції його формування та використання.  Виробничий потенціал аграрних формувань варто оцінювати не тільки за витратами на його формування, які постійно зростають, а виходячи із принципів цілеспрямованого вкладання засобів і забезпечення стійкого темпу зростання виробництва, з оцінки доходоутворюючих факторів, що тісно пов'язано з використанням інтенсивних методів функціонування підприємств як стимулюючих чинників їх розвитку. Найефективнішим, на думку авторів, для оцінки виробничого потенціалу сільськогосподарських підприємств є використання рейтингового методу з визначенням групових та інтегрального показників, що й обґрунтовано в статті.За результатами дослідження, найвищий рівень виробничого потенціалу мають великі суб’єкти аграрного господарювання Миронівського та Васильківського районів столичної Київської області (інтегральний індекс наявності виробничого потенціалу - відповідно 1,523 та 1,444).У статті набули подальшого розвитку методолого-методичні положення щодо оцінки виробничого потенціалу сільськогосподарських підприємств в контексті рейтингового методу, які дозволяють робити глибокий аналіз впливу окремих аспектів діяльності господарюючих суб’єктів на загальний рівень їх конкурентоспроможності з урахуванням тенденцій ринкових змін в умовах глобалізації.

The purpose of the paper is to investigate the level of competitiveness of agricultural and food products and to identify the possible areas of export development on the basis of scientific works and the existing system of national strategy of the agricultural sector development. The concept of «export potential of the agricultural sector” and its relation to the competitiveness of agricultural enterprises was revealed. The dynamics and the geography of Ukrainian export of agro-food products was investigated. The data of the State Statistics Committee of Ukraine for 2005—2016, Internet resources, and own observations served as the basis for the research. For the purposes of the research such groups of the most important product types were selected: cereals, namely: winter wheat, winter barley, corn; vegetable oil (sunflower, rapeseed, soybean), strawberry, sunflower and soya, etc., and as well as those that at the present stage are advocated and, thus, may significantly raise export potential in the long term (meat, poultry, dairy products, etc.). Change in the orientation of agro-export is associated with several factors: firstly, difficult political relationships with the Russian Federation resulted in a significant reduction in the volumes of exports to this country; secondly, the increase in exports to EU countries in connection to the signing of association agreement with the EU; thirdly, the continued growth of exports to the countries of Asia and Africa.It is the «competitiveness» that identifies the opportunities for the products supply on external markets, and this is a potential set of types of agro-food products, which domestic agricultural enterprises are able to export, that identifies the potential of the agricultural sector. Ukrainian producers have the advantage over the competitors in terms of the quality and products prices which is confirmed by the fact that domestic products are exported to more than 90 countries of the world. The use of the model of potential growth of export potential of the Ukrainian agro-products will able to fully provide growers with information about potential markets for products, to ensure the proper support for the promotion of products on foreign markets.

The main provisions of the Law of Ukraine «On public-private partnership» that contribute to the advancement and development of relations in such fields in Ukraine as public-private partnership, socio-economic relations, attraction of investments in the economy etc. are explored in the article. Attention is focused on the provisions of this Law that are debatable. The new regulations to this Law are proposed, as well as ways to improve relations inUkrainein the field of public-private partnership. Data on implementation of projects and formation of agreements of public-private partnership were announced on the official website of the Ministry of Economic Development and Trade of Ukraine as the empirical data.In order to develop economic relations and the settlement of relations in the field of PPPs inUkrainethe Law of Ukraine «On Public Private Partnership» was adopted.Results of the research of basic provisions of the Law give cause to suggest that public and private partners combine powers in order to implement socially important projects in various fields of economic activity throughout the whole country (national level) or on some territories of Ukraine (regional or local level). Implementation of public-private partnership projects meets the requirements of society, the public receives better products and services, construction and upgrading of infrastructure objects accelerates, is investments are attracting to economy, and so on.However, the development of public-private partnership inUkraineneeds to improve the provisions of the Law. They should be flexible and allow cooperation in various formats «public-private partner». A useful complement to the existing system of coordination and control would be the creation of a special body like operating in other countries — the Private Finance Initiative.

Izrazita samokritičnost spada med najpomembnejše psihološke dejavnike dovzetnosti za nastanek in vztrajanje psihopatologije. V raziskavi smo preverili psihometrične značilnosti in faktorsko strukturo slovaške različice Lestvice stopenj samokritičnosti. Uporabili smo opisno analizo, analizo zanesljivosti in veljavnosti ter konfirmatorno faktorsko analizo v okviru teorije odgovora na postavko (TOP). V nasprotju z angleško različico, kjer je klasična faktorska analiza pokazala dve dimenziji (ponotranjeno samokritičnost in primerjalno samokritičnost), je pri slovaški različici bolj sofisticirana faktorska analiza v okviru TOP pokazala obstoj treh faktorjev (ponotranjena samokritičnost, neugodna primerjava z drugimi in ugodna primerjava z drugimi). V prihodnje bo treba ta problem še podrobneje raziskati, ker predlagana trifaktorska struktura s povsem teoretičnega vidika ni najbolj smiselna. Zdi se, da ima Lestvica ravni samokritičnosti sprejemljivo raven zanesljivosti in veljavnosti, zato lahko priporočamo njeno uporabo za oceno ravni samokritičnosti z angleško in slovaško različico.

Analysis and Interpretation of Pressure-Decay Tests for Gas/Bitumen and Oil/Bitumen Systems: Methodology Development and Application of New Linearized and Robust Parameter-Estimation Technique Using Laboratory Data
Authors: Ratnakar R. R. , Dindoruk B..
Published: November 2018

Diffusion mixing is a dominant process in the absence of convective mixing in various reservoir processes, such as carbon dioxide (CO2) flooding of fractured reservoirs, heavy-oil and bitumen recovery, solution-gas-drive processes, and the gas-redissolution process in a depleted reservoir. In these processes, the diffusivity governs the rate and extent of mixing of light hydrocarbons/nonhydrocarbons with the oil that enhances the oil recovery through in-situ viscosity reduction. It is one of the key parameters for the design and understanding of displacement processes.

Because of its significance in various aspects of oil-recovery processes, several experimental and theoretical studies were recently performed on the measurement of gas diffusivity in oils. Experimental work most commonly uses the pressure-decay (PD) concept because of its simplicity and the potential extraction of other necessary parameters, such as Henry's constant. However, the parameter estimation from these tests is dependent on nonlinear regression, which might have several issues such as nonconvergence, nonuniqueness or multiplicity in solution, and high sensitivity toward noise and the time span of the data. Therefore, in this paper, Ratnakar and Dindoruk (2015) is extended and

New experimental data are provided from a PD test for CO2 diffusion into bitumen at 80°C and approximately 700 psi. A robust inversion technique for parameter estimation is presented for exponentially decaying late-transient data, which can be used with any PD model used in the literature. The validity and applicability of the inversion technique is demonstrated against numerical data that are generated for a PD system by solving a diffusion model with continuity in the state variable (using Henry's constant) and molar flux at the gas/oil interface. Most importantly, the issues with the nonlinear-regression technique are resolved using the linearized technique. The inversion technique presented in the work is dependent on a combination of linear regression and numerical integration using a modified, more-convenient form of the fundamental equations rather than a nonlinear regression on the fundamental equations as derived. This integral-based linear representation avoids the multiple solutions and can be used with limited data sets and/or when noise in the experimental data is significant, especially in industrial-grade experiments.
An Experimental Study of Emulsion Phase Behavior and Viscosity for Athabasca Bitumen/Diethylamine/Brine Mixtures

Published: November 2018

Water is the most dominant component in steam-based oil-recovery methods, such as steam-assisted gravity drainage (SAGD). The central question that motivated this research is whether in-situ bitumen transport in SAGD can be substantially enhanced by generating oil-in-water emulsion, in which the water-continuous phase acts as an effective bitumen carrier. As part of the initial stage of the research project, the main objective of this paper is to present the ability of organic alkali to form oil-in-water emulsions that are substantially less viscous than the original bitumen. Diethylamine (DEA) was used as the organic alkali in this research.

Experimental studies were conducted for emulsion phase behavior and viscosity for mixtures of Athabasca bitumen, DEA, and sodium chloride (NaCl) brine. Experimental variables included brine salinity, alkali concentration, water/oil ratio (WOR), temperature, and sample-aging time.

The phase-behavior study indicated that conditions conducive to oil-in-water emulsions are low alkali concentrations at salinities less than 1,000 ppm. For example, a single phase of oil-in-water emulsion was observed for 0.5, 1.0, 2.0, and 5.0 wt% DEA with WOR of 7:3 with no NaCl. The emulsion for 0.5 wt% DEA, 1,000 ppm NaCl, and WOR of 7:3 was a single-phase oil-in-water emulsion at temperatures up to 403 K at 35 bar. At lower temperatures, 323 and 298 K, flocculation of emulsions in these samples resulted in the separation between the bitumen-rich and water-rich oil-in-water emulsions. However, essentially all bitumen content was measured from the bitumen-rich oil-in-water emulsion. The oil contents in these emulsions were more than 70 vol% at 298 K and 57 vol% at 323 K.

Viscosities of these oil-in-water emulsions ranged between 85 and 115 cp at 1.0 seconds–1 and between 31 and 34 cp at 10.0 seconds–1, at 323 K. At 298 K, they ranged between 105 and 250 cp at 1.0 seconds–1 and between 48 and 74 cp at 10.0 seconds–1. Results in this research show that, compared with the original bitumen, bitumen-rich oil-in-water emulsions were less viscous by three to four orders of magnitude at 298 K, and less viscous by two orders of magnitude at 323 K.

Published: November 2018

The purpose of the studywas to review available data on various techniques for radical trachelectomy, inclusion criteria, advantages and disadvantages.

Material and methods.A systematic literature search was conducted in the electronic databases of Medline, Russian Science Citation Index, and Russian State Library in the interval time between 1997 and 2017.

Results.To date, only radical trachelectomy has shown its value regarding both aspects of oncologic and reproductive outcomes in patients with invasive cervical cancer. There are currently 5 approaches to radical trachelectomy: transvaginal approach with laparoscopic pelvic lymphadenectomy, abdominal, laparoscopic, robot-assisted and laparoscopic – vaginal approach. Each technique has its advantages and disadvantages.

Conclusion.Over the last years, radical trachelectomy has been recognized as a valuable fertility-preserving option for women of child-bearing age with invasive cervical cancer. Radical trachelectomy should be performed by highly skilled surgeons in specialized clinics.
OPTIMIZATION OF PRIMARY TRANSRECTAL MULTIFOCAL PROSTATE BIOPSY USING PERFUSION COMPUTED TOMOGRAPHY

Published: November 2018

Introduction. Primary transrectal multifocal prostate biopsy is the standard method for prostate cancer (PCa) verification, with the detection rate of 53 %. The purpose of the study was to improve findings of transrectal ultrasound-guided prostate biopsy (TRUS-biopsy) by its optimization due to perfusion computed tomography (PCT).

Material and methods.The study included 97 patients with indications for TRUS-biopsy. All patients underwent PCT of the prostate before biopsy. Prostate cancer was detected by PCT in 43 patients. These patients underwent standard primary transrectal multifocal prostate biopsy plus additional targeted punctures from areas of increased blood flow. The results of standard and targeted punctures were compared. The McNemar criterion was used to assess the statistical significance of the differences.

Results.There were no statistically significant differences in the incidence of PCa detection between standard and targeted punctures (p>0.05). However, statistically significant differences in the detection of PCa of different differentiation grades were found between standard and targeted punctures for PCa with a Gleason score of 8 (4 + 4). The detection rate of PCa with the Gleason score of 8 (4 + 4) was 5 % for standard punctures and 14 % for targeted punctures (p˂0.05). No one statistical method has been used to assess sensitivity and specificity, due to the absence of a «gold» standard (histological examination of the total amount of prostate tissue after radical prostatectomy).

Conclusion.The use of primary prostate biopsy optimized with PCT findings does not allow increase in the detection rate of PCa. However, this method improves the verification of PCa with a Gleason score of 8 (4 + 4) that can influence the risk stratification and selection of further therapeutic strategy.

This study aimed to identify the future changes in water requirements (ETc) of flue-cured tobacco by comparing estimated ETc values in the future with previous usage. This will provide a basis for estimating irrigation requirements, and help improve agricultural water use efficiency in the future. The Penman–Monteith equation and the single-crop efficient method were used to calculate the flue-cured tobacco ETc, net irrigation requirement (IR) and net irrigation requirement index (IDI) for the period 1956–2015, and the four Intergovernmental Panel on Climate Change (IPCC) AR5 emission scenarios were used to estimate ETc for two future periods (2046–2065 and 2081–2100) in the central Yunnan Province, China. The results showed that the IDI gradually decreased, along with the growth of flue-cured tobacco. The ETc, IR and IDI values increased with latitude in central Yunnan Province. Furthermore, the variations in the ETc over the whole growth period in the mid-21st century and late-21st century also tended to increase with latitude. In addition, based on the influence of climate variation on the ETc as assessed by a principal component analysis, precipitation was the main factor affecting flue-cured tobacco growth. This study contributes to the establishment of suitable irrigation systems for flue-cured tobacco at every growth stage in central Yunnan Province.

Public services require computer-based electricity supply. Not continuous electricity supply in some areas led to a power supply from an alternative power source becomes indispensable. One alternative power source is a solar cell. Solar cell is a sustainable source of electricity but power output is not constant depending on the sunlight. The power source is needed to anticipate the lack of power when the power generated by the solar cell is not enough.In this paper proposed a hybrid design that combines the power supply of electricity from the solar cell, the network provider of electricity, and batteries. This paper discusses methods of hybrid electric power from three sources. Hybrid power is usually done by PCC (Power Controlled Converter), which consists of a controlled power converter for each channel input, but in this study the method proposed hybrid power input specification in the form of a synchronization circuit PCC then replaced by a diode circuit.The design of hybrid power supply in this study resulted in the specification input from the solar cell with Vmp channels (maximum power voltage) 35VDC Voc (open circuit voltage) 43.78VDC, channels of electricity provider with the already converted with SMPS (Switched Mode Power Supply) to 35VDC, and channels of a battery with a minimum voltage of 21VDC maximum 27.6VDC. The test results showed that the implementation of the proposed hybrid method can perform a single capture or hybrid power, and can transfer power between the source retrieval without pause. Implementation of the proposed hybrid method has a 21VDC output voltage range - 43.78VDC and efficiency of 98.6% - 99.5%.

One of the diagnosis procedures for acute lymphoblastic leukemia is screening for blood cells by expert operator using microscope. This process is relatively long and will slow healing process of this disease which need fast treatment. Another way to screen this disease is by using digital image processing technique in microscopic image of blood smears to detect lymphoblast cells and types of white blood cells. One of essential step in digital image processing is segmentation because this process influences the subsequent process of detecting and classifying Acute Lymphoblastic Leukemia disease. This research performed segmentation of white blood cells using moving k-means algorithm. Some process are done to remove noise such as red blood cells and reduce detection errors such as white blood cells and/or lymphoblastic cell  that’s appear overlap. Postprocessing are performed to improve segmentation quality and to separate connected white blood cell. The dataset in this study has been validated with expert clinical pathologists from Sardjito Regional General Hospital, Yogyakarta, Indonesia. This research produces systems performance with results in sensitivity of 85.6%, precision 82.3%, Fscore of 83,9% and accuracy of 72.3%. Based on the results of the testing process with a much larger number of datasets on the side of the variations level of cell segmentation difficulties both in terms of illumination and overlapping cell, the method proposed in this study was able to detect or segment overlapping white blood cells better.

Sembilan pohon mangium umur 4 tahun yang digunakan dalam penelitian ini berasal dari Kabupaten Wonogiri, Jawa Tengah. Adapun sifat-sifaf kayu yang diuji adalah kerapatan dasar, perubahan dimensi, rasio T/R, keteguhan lengkung statis (MOE dan MOR), keteguhan tekan sejajar dan tegak lurus serat. Selanjutnya data yang diperoleh diuji dengan one-way ANOVA. Sebagai hasilnya, sifat fisika dan mekanika kayu yang diuji menunjukkan hasil yang tidak berbeda nyata pada tiga kategori kecepatan tumbuh yang berbeda, kecuali pada penyusutan radialnya. Selanjutnya, kerapatan dasar berkorelasi positif secara signifikan terhadap penyusutan radial dan tangensial serta kekuatan tekan sejajar dan tegak lurus serat. Hal ini menunjukkan bahwa kerapatan dasar merupakan indikatoryang bagus untuk mempredikasi sifat fisika dan mekanika kayu mangium. Effect of Growth Rate on Physical and Mechanical Properties of 4-year-old Acacia mangium Wood from Wonogiri, Central JavaAbstractIncreasing solid wood demand provides an opportunity to fast-growing wood species such as Acacia mangium as semi construction and construction materials. In general, the quality of wood is affected by growth characteristics such as radial growth rate. The study about effect of growth rate on the properties of mangium wood is limited in Indonesia. Therefore, this study aimed to determine the physical and mechanical properties of mangium wood at different growth rates. Furthermore, relationship between basic density and other properties was clarified. The nine mangium trees of 4-year-old used in this study were planted in Wonogiri Regency, Central Java. Basic density, shrinkage, T/R ratio, static bending strength (MOE and MOR), compressive strength parallel and perpendicular to grain were determined. The results were analyzed with one-way ANOVA. As a result, the physical and mechanical properties of the woods showed no significant difference in three different categories of growth rates, except for radial shrinkage. Furthermore, the basic density is positively significant correlated with radial and tangential shrinkage and also compressive strength parallel and perpendicular to grain. Based on these results, it is suggesting that basic density is a good indicator for predicting physical and mechanical properties of mangium wood.

Published: November 2018

Background and Objectives: The purpose of this study was to determine the effectiveness of the Society of Teachers of Family Medicine’s Smiles for Life: A National Oral Health Curriculum on the knowledge and attitudes of physician assistant students regarding oral health.
Methods: Seventy-two didactic year physician assistant students from one physician assistant program were surveyed to assess their knowledge and attitudes regarding oral health prior to starting the Smiles for Life oral health curriculum. The students were electronically surveyed a second time 1 week after completing all online modules in the Smiles for Life oral health curriculum.
Results: Precourse and postcourse survey response rates were 57% and 36%, respectively. The mean of the attitude statements increased from 3.20 on the precourse survey to 3.87 on the postcourse survey (P=.0012). The mean number of correct responses on the knowledge questions increased from 6.83 on the precourse survey to 9.85 on the postcourse survey (P<.0001).
Conclusions: Statistically significant improvements in the attitudes toward oral health and oral health knowledge of physician assistant students after completion of the Smiles for Life curriculum were observed. This study illustrates the effectiveness of the Smiles for Life curriculum as an interprofessional educational experience. This curriculum can be completed online and does not require faculty expertise in oral health, thus removing previously cited barriers to incorporating oral health into the physician assistant curriculum.

Published: November 2018

Background and Objectives: Reports of innovations in evidence-based medicine (EBM) training have focused on curriculum design and knowledge gained. Little is known about the educational culture and environment for EBM training and the extent to which those environments exist in family medicine residencies in the United States.
Methods: A literature review on this topic identified a validated EBM environment scale intended for learner use. This scale was adapted for completion by family medicine residency program directors (PDs) and administered through an omnibus survey. Responses to this scale were analyzed descriptively with program and PD demographics. An EBM culture score was calculated for each program and the results were regressed with the correlated demographics.
Results: In our adapted survey, family medicine PDs generally rated their residencies high on the EBM culture scale, but admitted to challenges with faculty feedback to residents about EBM skills, ability to protect time for EBM instruction, and clinician skepticism about EBM. In linear regression analysis, the mean summary score on the EBM scale was lower for female PDs and in programs with a higher proportion of international medical school graduates.
Conclusions: To improve the culture for EBM teaching, family medicine residency programs should focus on faculty engagement and support and the allocation of sufficient time for EBM education.
