Security Standards

Recently the study of economics of internet has emerged as an emerging field of study. The workstations being distributed across the network along with the users having varied interests has made this study very important from an information security and policy designing point of view. The main purpose of any framework design is to keep up with the security standards of confidentiality, integrity and availability without being an overburden on the deployer. The same goes for the users, the Quality of Service (QoS) should be in accordance with what they pay for. The concept of “tragedy of commons” plays an important role in distributing the limited resources of the internet. In this, the users because of their own self-interest destroy the collective interest of a community sharing the resource. A sustainable pricing strategy is the one which is able to cater to the competitive advantage of different network providers offering the same set of services but on varied prices. A pricing mechanism will help in differentiating the services offered to the users, but another important task is of fixing the incentives. The pricing strategy plays a very important role in facilitating varied kinds of QoS requirements. Security professionals have realized that while designing any security mechanism it is vital to keep in consideration the “theory of mind” which explains the way the attackers and benign users take decision to deceive of remain loyal to the system. So, studying the incentive and payment structure from economic point of view is important.

Mechanical separation of light packaging waste is a useful practice for improving the quality of the recyclable waste flows and its exploitation in a frame of the circular economy. Materials Recovery Facilities can treat from 3000 to 5000 tons per year of light packaging waste. Concerning the plastic content, this is divided in four flows: PET, HDPE, other plastics, and waste rejects. The last two are generally used for energy recovery. For improving the quality of the recyclable plastic waste, a manual separation is required for reducing the impurities detectable in the final products. However, this practice could enhance the risk at work of the operators, which should be constantly monitored. This article explores the main differences of a manual separation and of a mechanical separation, assessing the costs and the health risk for the workers. The analysis started from the situation in an Italian Materials Recovery Facility, generalizing the context; a future scenario with the application of a mechanical separation is theoretically introduced. The main results obtained suggest that the manual separation plant improves the quality of the material, though increasing the risk of the operators due to the possible contact with sharp waste, sanitary danger, and risk of injuries for the mismanagement of machines, among others. The mechanical separation can be considered a real advantage from an economic point of view, since the operating costs are lower and the investment could be recovered in around 10 years, in an Italian-like context. On balance, on the one hand, the article provides indications for the private sector for improving the management of a Materials Recovery Facility, while, on the other hand, it detects the main pros and cons of both methodologies.

The processes of optimization of the production plan according to certain criteria by modeling were investigated. Achieving effective results directly depends on the optimal production plan. The most important thing in determining the optimal production plan is the choice of modeling criteria. For the most part, the quality of decisions is characterized not by one but by many incomparable criteria. Therefore, it is necessary to make decisions based not on one but on many criteria. This so-called multi-objective optimization problem. For solving such problems is widely used mathematical methods. Mathematical approach can be used to solve problems in any particular activity as mathematics abstracted from specific features characteristic of a particular solution. Therefore, from the point of view of mathematics, the optimal result can be obtained with various established criteria, but from the economic point of view it is important to choose the ones that are of decisive importance. That is, their weight is important for the consumer when making a purchase decision, and for the manufacturer – in terms of production capabilities of certain types and results (production efficiency). The basis of the operation of any enterprise is a production program (production and sales plan). The main task of the production plan is to meet the needs of consumers in high-quality products, which are produced with the best use of resources, on the one hand, and the enterprise to get the maximum profit, on the other. With this in mind, a two-criteria optimization model that allows to make a production plan was proposed. The plan ensures that products are produced with the best use of available resources and at the same time ensures maximum quality of manufactured products and maximum profit from sales of these products. The solution of the problem with two objective functions and linear constraints is achieved by step-by-step solution of the proposed mathematical model of optimization of the production plan using the method of sequential restrictions. The simplex method was also used. An example shows an algorithm for solving the optimization problem.

Hygienic Conditions

The aim of this study is to evaluate the hygienic quality of the dishes cooked and sold by the women traders in the town of Korhogo. The study was carried out with 45 restaurants in the town of Korhogo. It consisted on the one hand, a survey based on the Ishikawa diagram in order to assess the hygienic conditions, and on the other hand of microbiological analyses of the ready-to-serve meals. A total of 90 samples were taken, including 2 dishes per restaurant, respectively consisting of one hot and one cold dish. Generally, results showed that hygienic conditions were unsatisfactory based on the utilized guidelines. From a microbiological point of view, the meal samples were 75.2% satisfactory, 7.6% acceptable and 17.2% unsatisfactory. In view of these results, it appears essential to improve hygiene conditions by greater involvement of the official services involved in training these traders and monitoring compliance with good hygiene practices and the establishment of a program of cleaning and disinfection of premises and equipment.

Diagnostic Pathways

AbstractDiagnostic pathways are an essential subset of clinical pathways and a logical consequence of DRG-based reimbursement. They combine the principle of stepwise reflex and reflective testing with a management concept that helps to fulfill medical needs with organizational and economic efficacy. The two most common formats describing diagnostic pathways are graphical decision trees on paper and “if…then…else” rules on computers. From a laboratory point of view, diagnostic pathways represent “smart” test profiles, which – in contrast to conventional (inflexible) profiles – are not necessarily worked off completely, but just to a point, where a diagnostic decision can be made. This improves the cost-effectiveness of laboratory testing, while making sure that no essential tests are missed. The paper describes benefits and limitations of diagnostic pathways from a medical, organizational, and economic point of view. Their major advantage is also their major drawback, since they make the diagnostic process on the one hand extremely straight-forward and transparent, while on the other hand oversimplifying the underlying medical decision principles. This may provoke the abuse of their primarily medical intentions for mere economic purposes.

Taking Responsibility

This paper presents a positive philosophy of life developed to support and inspire patients to take more responsibility for their own lives and to draw more efficiently on their known or hidden resources. The idea is that everybody can become wiser, use themselves better, and thus improve quality of life, subjective health, and the ability to function.To be responsible means to see yourself as the cause of your own existence and state of being. To be the one who forms your own life to your liking, so that others do not shape it in the way they prefer to see you. Seen this way, taking responsibility in practice is one of the most difficult things to do. One of the greatest and most difficult things to do in this context is to be able to love. To be the one who loves, instead of being the one who demands love, care, awareness, respect, and acceptance from somebody else.Since almost all of us have had parents who maybe loved us too little and mostly conditionally, we all harbor a deep yearning to be loved as we are, unconditionally. A lot of our energy is spent trying to find recognition and acceptance, more or less as we did as children from our parents, who created the framework and defined the rules of the game. But today, reality is different. We have grown up and now life is about shaping our own existence. So we must be the ones who love. This is what responsibility is all about. Taking responsibility is, quite literally, moving the barriers in our lives inside ourselves. Taking responsibility for life means that you are willing to see that the real barriers are not all these external ones, but something that can be found within yourself. Of course there is an outside world that cannot be easily shaped according to your dreams. But a responsible point of view is that although it is difficult, the problem is not impossible; it is your real challenge and task. If there is something you really want, you can achieve it, but whether it happens depends on your wholehearted, goal-oriented, and continuous attempts. This paper describes the philosophy about seizing the meaning of life and becoming well again, even when there is little time left.

The study was carried out during summer of 2012 with BARI hybrid tomato 4, planted in the Olericulture farm of Bangladesh Agriculture Research Institute, Joydebpur, Gazipur, Bangladesh to find out the response of plants to some staking and pruning treatments on yield, fruit quality and cost of production. A two factor experiment consisting of three staking methods and four level of pruning, laid out in complete block design with three repetitions. Plants were staked on inverted „V? shaped staking, high platform and string. The plants were pruned to two stem, three stem, four stem and no pruning as control. Results showed that significantly the highest total number of fruits per plant (37.1), marketable fruits per plant (33.7), yield per plant (1.68 kg) and total yield (44.6 t/ha) were produced by the plants having the treatment string staking with four stem. The highest fruit set (43.50%) was found in the plants staking with string having three stems. Plants grown on string staking allowing two stem gave the maximum length (4.71 cm), diameter (4.83 cm) and weight (53.4g) of single fruit as well as maximum fruit firmness (3.43 kg-f cm-2). From the economic point of view, it was apparent that summer tomato produced by string staking with four stem pruning exhibited better performance compared to other treatment combinations in relation to net return and BCR (2.10).Bangladesh J.

Choosing a high-speed rail vehicle depends on many factors. On the one hand, there are requirements for ensuring the quality of service for passengers, on the other hand, there are constraints resulting from the parameters of available infrastructure. Also a relation of the benefit and financial costs associated with the purchase and the operation of rolling stock is essential. Technical characteristics of vehicles selected for operating a particular system is a compromise between the three groups of requirements. In this article technical parameters of railway infrastructure and rolling stock are classified and then analysed from the TSI requirements point of view.

The goal of civil engineering has always been the research and implementation of methods, technologies, and infrastructures to improve the community’s quality of life. One of the branches of civil engineering that has the strongest effect on progress is transport. The quality of transport has a profound economic and social impact on our communities regarding trade (freight transport) and city livability (public transport systems). However, innovation is not the only way to improve the features above-mentioned, especially public transport, considering that it is usually beneficial to enhance and repurpose vehicles with appropriate adjustments to offer more efficient services. Other perspectives that influence public transport systems are the costs and times of design and construction, maintenance, operating costs, and environmental impact, especially concerning CO2 emissions. Considering these issues, among the various types of existing public transport systems, those of the so-called Bus Rapid Transit (BRT) offer worthwhile results. The BRT system is a type of public road transport operated by bus on reserved lanes, and it is significantly profitable, especially from an economic point of view, in areas where there are existing bus routes. Nonetheless, for the construction of works minimization, it is closely linked to other features that improve its usefulness, depending on the vehicles’ quality such as capacity, but above all, the propulsion or driving autonomy that would guarantee high efficiency. This paper introduces an analysis of some BRT systems operating worldwide, presenting the background, general technical features, and the correlation with autonomous vehicles.

Although the European rules on water, which are mainly based on the Water Framework Directive (WFD 2000/60/EC), have been in force for many years, the quality of waters in Europe still have huge room for improvement before they can fulfil the objectives set by the WFD and by its “daughters Directive”. Two questions are key here: Are the European rules adequate for this challenging goal? If yes, are the rules applied homogeneously and correctly in European Union Countries or do many issues remain which prevent their full implementation? This article provides a broad overview of water issues in Europe, focusing on the level of fulfillment of requisites from EU legislation and the level of its implementation in Member States. This point of view has been adopted because an uneven implementation of EU laws prevents several European citizens from fulfillment of their right to a healthy environment and a good water resource quality and, furthermore, endangers the level playing field across Europe, from a social and economic point of view.

Purpose: The present work seeks analyze the profitability and the financial situation of the main Catalan alpine ski resorts, with the objective to check if these are sustainable from an economic point of view, taking into account the external factors that affect him.Design/methodology: With the objective to carry out the study of profitability and financial situation, we obtained the financial states of the main Alpine ski resorts of the Catalan Pyrenees: Baqueira-Beret, Masella, Boí Taüll, Vallter 2000, La Molina, Vall de Núria and Espot Ski-Port Ainé, for the periods comprised between 2011-2015 and we proceeded to apply a series of economical and structural ratios with the purpose of establish a diagnostic on his situation.Findings: The results show that the Baqueira-Beret and Masella resorts are the only that obtain profits, whereas the rest of resorts obtain losses in all the periods analyzed. With regard to the financial situation, the results reveal that the level of indebtedness of the resorts is, in general reduced, arriving to the conclusion that the majority of them are not sustainable from a strictly economic point of view.Research limitations/implications: The main limitations of this work are on the one hand that the conclusions are obtained from a period of analysis of five years (2011-2015), and the second, they are circumscribed to a determinate region.Practical implications: The results of this work can help to take decisions so much to the ski resorts managers as to the public administrators for implementing strategies to achieve diversify the offer and improve the results.Social implications: Nowadays the majority of the ski resorts have been rescued or purchased by the Administration. We can deduce that it keeps by the incomes that generate his existence. That is to say, by the positive externalities that generates in the territory where they are situate.Originality/value: The present research focuses in the financial study of a little studied sector as they are the ski resorts and the snow tourism with the enormous importance that has in the economy of the region and in the territorial development. The agents interested are so much the public administrations like the managers of this type of firms.
