STATE REGULATION OF INVESTMENT INSURANCE COMPANIES IN UKRAINE

STATE REGULATION OF INVESTMENT INSURANCE COMPANIES IN UKRAINE

The paper deals with the peculiarities of financial provision of public and private accident insurance. Analyzes the methodology of forming insurance premium rates in private accident insurance. The study examines the practice of reforming the financial security of the state social insurance against accidents. The results show need to implement scientifically proven approach to determining premium rates in the state social insurance based on mathematical statistics and actuarial calculations to ensure that such conditions on the one hand, can insure the risk, and the other – to provide the insurer the ability to perform insurance obligations' commitments. One of the promising areas of improvement Accident Insurance determines to define increasing the role of the private sector to create and attraction of investments, financing, reduce costs, and provision of insurance services on insurance against accidents at a qualitatively higher level. The results show the need to consider the usefulness of a mixed provision of services to accident insurance under state or non-state system, and the viability and effectiveness of the combination of these systems.

stage, the content of manganese was made up with an addition of ferromanganese and the melt was held for 3 minutes. During holding of the melt and before tapping, the temperature of liquid iron was measured with a thermocouple. The melt was transferred to a ladle, which was next transported to the casting stand and molten metal was poured into the previously prepared moulds. Test bars with a φ 15 mm diameter and castings were made following the production regime adopted by HARDKOP Foundry at Trzebinia. As a next step, specimens were prepared for metallographic examinations. Chemical composition of the cast iron phase constituents was examined using a JEOL 500LV scanning electron microscope with attachment for X-ray microanalysis (EDS).

Contribution To The Study Of Reproduction Parameters Of The European Conger Eel Conger Conger Linnaeus 1758 From The Western Algerian Coasts Oran Bay Algeria

Contribution To The Study Of Reproduction Parameters Of The European Conger Eel Conger Conger Linnaeus 1758 From The Western Algerian Coasts Oran Bay Algeria

The demographic structure obtained for the European conger eel characterized a population exclusively composed of young individuals. In this study, it was impossible to know the fishing gear used during the fishery. The small populations that dominate in the study area can be explained by the gradual increase in fishing effort expressed by the increase in the number of trawlers and small boats and exploitation the same areas of fishing. However, Sullivan et al. (2003) showed in Irish coastal waters the absence of small fish between 68 to 80 cm. This was associated with the selectivity of the fishing gear rather than indicating the absence of the small individuals. Similar results have been already reported by Correia et al. (2009). The allometric scaling 'b' for both females and males of C. conger was greater than 3 and was consistent with other results obtained in other area (Tab 2).

The analysis of solidification process of ferritic-austenitic cast steel

The analysis of solidification process of ferritic-austenitic cast steel

One of the most common defects leading to the rejection of faulty castings made of duplex cast steel is hot cracking. Hot cracking – differently from cold cracking which occur on cooling, when the material exhibits already distinct elastic properties – proceeds in the semi-solid state, particularly when the temperature of solidifying casting is close to the equilibrium solidus point. There exist a range of temperatures in the vicinity of the solidus point within which the solidifying metal shows very small deformation ability and small strength. Therefore even little stresses occurring at the solidification stage and caused by density difference between ferrite and austenite, or restricted shrinkage, or various temperature gradients, can be the reason of hot cracking. Copper addition, as it is used in cast steel grades implemented in Polish power industry applications, decreases the temperature of the end of solidification, thus affecting beneficially the surface reproduction quality, but on the other hand it can promote, along with several other elements contained in duplex cast steel, the peritectic transformation during the last stage of solidification. The presence of peritectic solidification, i.e. strictly speaking the structural stresses accompanying that process, is the well-known and significant reason of the increased steel defectiveness in the continuous steel casting (CSC) technology if the steel with carbon content promoting the peritectic transformation is processed.

Evaluating the influence of selected parameters on sensitivity of a numerical model of solidification

Evaluating the influence of selected parameters on sensitivity of a numerical model of solidification

For every analyzed case it was assumed that in the range of variability of each parameter there are 4 points (p=4). The number of simulation needed to be conducted depends on the number of the studied physical model parameters k, as well as on how many times the matrix B* was created, and it is equal to r (k+1). Hence the number of computer simulations ranged between 80 for cases shown in Figures 3, 7, 8 and 9 through 128 and 320 for Figures 4 and 5 respectively, up to 640 for the case from Figure 6.

The Impact of E-Commerce Securi ty, and National Environment  on Consumer adoption of Intern et Banking in Malaysia and  Singapore

The Impact of E-Commerce Securi ty, and National Environment on Consumer adoption of Intern et Banking in Malaysia and Singapore

Relative advantage is defined as the extent to which a person views an innovation as offering an advantage over previous ways of performing the same task (Roger, 1983; Agarwal & Prasad, 1997). Because Internet banking services allow customers to access their banking account from any location 24 hours a day and 7 days a week, it provides an enormous advantage and convenience to users (Tan & Teo, 2000). It also gives customers greater control over managing their finances, as they are able to check their accounts easily. Besides, a customer’s Internet experience, his or her banking needs can affect his adoption. As there are more financial products and services, it is expected that individuals with many financial accounts and who subscribe to many banking services will be more inclined to adopt Internet banking. Tan and Teo (2000) has reported that potential adopters of Internet banking services are likely to own multiple banking accounts and subscribe to various banking services. Rogers argues that potential adapters, who are allowed to experiment with an innovation will feel more comfortable with the innovation and are more likely to adopt it. Thus, if customers have the opportunity to try the innovation, certain fears of the unknown may be minimized. Government policy could also aid or hinder Internet diffusion (Mbarika, 2002). This is consistent with the national systems of innovation theory that posits that government policies may encourage or mandate technology development and adoption (King et. al., 1994; Wolcott et. al., 2001). Tan and Teo (2000) suggest that the greater the extent of government support for Internet commerce, the more likely Internet banking will be adopted, thus, confirming Goh’s (1995) suggestion that governments can play an interventionist and leading role in the diffusion of innovation. Potential users in turn would view new applications such as Internet banking services more favorably and hence be more like to use them. Thus, the second alternative hypothesis is:

The Concept of Early Vascular Ageing – An Update in 2015

The Concept of Early Vascular Ageing – An Update in 2015

Arterial ageing is a process that can be quantiied, at least to some degree, by measurement of pulse wave velocity along the aorta, the largest elastic artery, as a marker of arterial stifness. In recent years the new concept of early vascular ageing (EVA) has been developed by a group of mostly European researchers and some reviews have been published. Based on a lecture given at the European Association for the Study of Diabetes (EASD) Meeting in Vienna 2014, this review was written to describe recent developments in research dedicated to EVA and new emerging aspects found in studies of families at high cardiovascular (CV) risk. This brings new perspectives related to genetics, telomere biology, and the role of gut microbiota. Even if EVA has been described in general terms there is still no unifying deinition available and no direct treatment, only recommendations for conventional CV risk factor control. However, a new intervention study (SPARTE) is ongoing in France with a randomised design to treat arterial stifness in patients with hypertension versus conventional treatment strategies. Results are expected in a few years and will be of importance in deining the role of arterial stifness, a core feature of EVA, as a target for treatment.

Model of knowledge representation about materials in the form of a relational database for CAPCAST system

Model of knowledge representation about materials in the form of a relational database for CAPCAST system

The diagram in Figure 1 shows the basic requirements for a material-related module in a CAPCAST system. The system user (manufacturer or his employees) introduces to the system the customer's technical requirements concerning the material, and also gives the current price/cost of materials and processing. Entering current prices is necessary to keep the calculations up- dated all the time against the ongoing market price fluctuations. However, this operation does not have to be performed each time when the type of material is determined; it is enough to provide current prices in the system keeping pace with the rate of changes in the market and introducing these changes with the same fre- quency with which the fluctuations occur in the market (e.g. once a week, once a month, etc.). The user will have at his disposal an intuitive and easy to use interface, which should correspond in its

Criterion for selection the optimal physical and chemical properties of cobalt aluminate powder used in investment casting process

Criterion for selection the optimal physical and chemical properties of cobalt aluminate powder used in investment casting process

important factor, which influences the grain size and the quality of the casting is the amount of modifier introduced into the mould. The amount of cobalt aluminate in the primary slurry is highly variable, (ranging from 1 to 10% or higher) and depends on the specification requirements, the alloy being casted, the section thickness, and other factors [9-11]. On the grounds of the obtained results it was found that the optimal concentration of cobalt aluminate powder in ceramic mould to produce casting elements made from Inconel 713C superalloy is about 5-6%mass, however in case of S6K - 2%mass. The higher concentration of modifier does not change the grain size significantly and does not improve mechanical properties of castings. So the next step in the study is to define what chemical and physical properties should cobalt aluminate characterize in order to archive the best nucleating effect.

An Advancement To The Security Level Through Galois Field In The Existing Password Based Technique Of Hiding Classified Information In Images

An Advancement To The Security Level Through Galois Field In The Existing Password Based Technique Of Hiding Classified Information In Images

Such mediums are the best cover media to hide messages. Digital images are the most widespread cover files used for SG, due to their high embedding efficiency and the insensitivity of the human visual system (HVS) [3]. It is not necessary that the cover and message have a homogeneous structure. For example, it is possible to embed a recording of an audio stream message inside a digital image [4]. The simplest steganographic techniques embed the bits of the message directly into the least significant bit (LSB) plane of the cover image in a deterministic sequence [5, 6]. Different steganographic techniques focus on a variety of requirements such as robustness, tamper resistance, imperceptibility, security and capacity [7-10]. Our technique is focused on providing high security and high speed operation while maintaining imperceptibility. We are using here Galois Encoder to provide high operational speed while maintaining the security intensively. The 2BC (two bit code) technique is the basic steganography technique we are using with the Galois Operation. Galois field arithmetic has received considerable attention in recent years due to their application in public-key cryptography schemes and error correcting codes.[12] We are here using the 2BC(two bit code) and Galois Field algorithm to achieve the goal of the maximum reception of the original message signal while maintaining the losses and enhancing the speed of operation. Different steganographic techniques focus on a variety of requirements such as robustness, tamper resistance, imperceptibility, security and capacity. Our embedding technique is focused on providing security while maintaining imperceptibility. Our method can work in any transform domain, but we are illustrating the ideas in the spatial domain for convenience. The rest of the paper is divided among the following sections: section 2 explains the existing passcode based technique which involves the matching process and the embedding techniques, section 3 describes the Galois operation, section 4 and 5 explains the data transmission and retrieval process using the Galois Encoder and decoder, section 6 contains simulation result and section 7 summarizes the Conclusion.

The Influence Of CSR Awareness On Consumer Purchase Decision Of A Telecommunication Network In Ghana A Case Of La Nkwantanag Madina Municipality

The Influence Of CSR Awareness On Consumer Purchase Decision Of A Telecommunication Network In Ghana A Case Of La Nkwantanag Madina Municipality

on overall company evaluations‖. Murray and Vogel (1997) have investigated the effect of associated CSR practices on consumers and presented similar findings. The CSR activities mentioned in the research are, for instance, environmental protection practices (energy conservation), engagement in acts to promote human welfare, corporate social marketing (electric safety education for schoolchildren), contribution to the economic development of the region, and consumer protection program. Their research found that CSR programs lead to improved customer attitudes towards the firm, including beliefs about the company‘s honesty, consumer responses, and increased support for the firm in labor or government disputes. Mohr et al. (2001) conducted a consumer interview project for investigating the impact of firms‘ CSR on consumer behavior. How well are consumers aware of the CSR level of individual firms? Are the purchase decisions of consumers affected by a firm‘s CSR, and how much? How do consumers think about firms‘ motivation for being socially responsible? Mohr et al. (2001) found that consumers are positive to business in general. It is not wrong to pursue economic interests. Consumers expect firms to be socially responsible. The attitudes of consumers toward socially responsible firms are more positive than toward irresponsible firms. Consumers are aware that socially responsible firms are helping themselves by practicing CSR. But this perception of consumers does not harm the positive consumer evaluations toward socially responsible firms. The study of Mohr et al. (2001) is enlightening for researchers, managers and policy makers. For managers specifically, it is clear that consumers do care about a firm‘s CSR and act accordingly. Some consumers are highly ethical in

Analytical Determining Of The Steinmetz Equivalent Diagram Elements Of Single-Phase Transformer

Analytical Determining Of The Steinmetz Equivalent Diagram Elements Of Single-Phase Transformer

Abstract: This article presents to an analytical calculation methodology of the Steinmetz Equivalent Diagram Elements applied to the prediction of Eddy current loss in a single-phase transformer. Based on the electrical circuit theory, the active and reactive powers consumed by the core are expressed analytically in function of the electromagnetic parameters as resistivity, permeability and the geometrical dimensions of the core. The proposed modeling approach is established with the duality parallel series. The equivalent diagram elements, empirically determined by Steinmetz, are analytically expressed using the expressions of the no loaded transformer consumptions. To verify the relevance of the model, validations both by simulations with different powers and measurements were carried out to determine the resistance and reactance of the core. The obtained results are in good agreement with the theoretical approach and the practical results.

Factors Affecting The Adoption Of Mhealth In Maternal Health Care In Nakuru Provincial General Hospital

Factors Affecting The Adoption Of Mhealth In Maternal Health Care In Nakuru Provincial General Hospital

Abstract : Access to timely and quality maternal health care remains to be a major development challenge in many developing economies particularly in Kenya. The country’s system of providing maternal health care also continue to be anchored on conventional methods of physical presence of the patient and the doctor in a hospital setup. The country’s ICT and health policies also place very little emphasis on the use of these platforms. This study therefore sought to establish the factors affecting the adoption of mHealth by focusing on maternal health in Nakuru Provincial General Hospital. Objectives of the study were: to determine the extent to knowledge and awareness affects the adoption of mHealth in maternal health care at Nakuru PGH, to identify the government policies affecting the adoption of mHealth in maternal health care at Nakuru PGH, to assess how access to technology affects the adoption of mHealth in maternal healthcare, to establish the effects of ICT infrastructure on the adoption of mHealth in maternal health care and to identify the cost aspects affecting the adoption of mHealth in maternal health care at Nakuru Provincial General Hospital. It is envisaged that the study could provide useful information on the adoption of mHealth in managing maternal health care in Nakuru Provincial Gener al Hospital. Descriptive survey research design will be used where all the medical staff and patients of Nakuru Provincial General Hospital was surveyed. The study population therefore was made up of 24 medical staff and 3460 mothers visiting the antenatal clinic selected using clustered random sampling technique. The main instrument for primary data collection was the questionnaire. Data analysis was then done using both descriptive and inferential statistics. Descriptive statistics to be used include frequency counts, percentages, and measures of central tendency

where is a set of linear restrictions that transforms the unrestricted model (1) on restricted model (2). 8 In our case, the restriction implies that the age, trend and (orthogonal) time dummies are sufficient to explain the behavior of each estimated statistic order across cells and over time. Imposing the restrictions means estimating weighted least squares regressions on the grouped data, for each quantile and education group separately. This procedure will give us consistent estimates of . Under the null that the restrictions are valid, the minimized value follows a chi-square distribution with degrees of freedom equal to the number of restrictions. In order to construct the test statistics, we only have to sum up the weighted squared residuals, that is, the estimated percentiles minus the predicted values minus the orthogonal time dummies.

Modeling of Two-Stage Solidification: Part II Computational Verification of the Model

Modeling of Two-Stage Solidification: Part II Computational Verification of the Model

In the work we assume that the first stage of solidification is the same for both modified and unmodified alloys. Thus, the same dendritic nucleation density is used in both cases. However, we should keep in mind that modifier may affect the dendritic structure formation. In the second stage of the solidification, the nucleation process unfolds in slightly different way, depending on the eutectic transformation mode. In such case nucleation phenomena depends on different densities and different algorithms, as explained in Part I. The authors of the series of papers [3, 6, 7] investigated solidification of modified and unmodified hypoeutectic alloys, and indicated that the difference in nucleation densities for eutectic structure must exists. In [6] McDonald et al. claim that the difference in nucleation density and the size of eutectic grains is “drastic”. It should be noted, that due to the fact that eutectic transformation modes are relatively new area of research, only limited experimental data is available. Keeping this in mind, in our approach we assumed that in the case of modified alloys the nucleation density for eutectic structure is the same as for the dendritic structure. In turn, for the second

Statistical Assessment of the Effect of Chemical Composition on Mechanical Properties of Hypereutectic AlSi17CuNiMg Silumin

Statistical Assessment of the Effect of Chemical Composition on Mechanical Properties of Hypereutectic AlSi17CuNiMg Silumin

The paper presents a statistical assessment of the effect of chemical composition on mechanical properties of hypereutectic AlSi17 silumin, which is expected to act as a counterpart of alloys used by automotive industry and aviation for casting of high-duty engine parts in West European countries and USA. The studies on the choice of chemical composition of silumins were preceded by analysis of the reference literature to state what effect some selected alloying elements and manufacturing technology may have on the mechanical properties (HB, R m and A 5 ) of these alloys. As alloying additives, Cu, Ni and Mg in proper combinations were used. The alloy after
