Economical aspects of the CCS technology integration in the conventional power plant
Authors: Slavu Nela , Dinca Cristian 
Published: August 2017

Abstract
One of the way to reduce the greenhouses gases emissions generated by the fossil fuels combustion consists in the Carbon Capture, Transport and Storage (CCS) technologies utilization. The integration of CCS technologies in the coal fired power plants increases the cost of the energy generation. The CCS technology could be a feasible solution in the case of a high value of a CO2 certificate but for the present value an optimization of the CCS technology integration in the power plants is expected. However, for reducing the cost of the energy generated in the case of CCS integration in the power plants, a parametrical study optimization of the CO2 capture process is required. In this study, the chemical absorption process was used and the monoethanolamine with 30 wt. %. The objective of this paper is to analyze the effects of the package type used in the absorption column on the size of the equipment used and, on the energy cost of the power plant with CO2 capture process consequently. The packages types analyzed in this paper are metal Pall rings with different sizes and the rings are made of different metals: aluminum, nickel, cooper, and brass. In the case of metal Pall rings, the utilization of different material has an impact on the absorption column weight. Also, Pall rings made of plastics (polypropylene and polyethylene) were analyzed. The comparative assessment was achieved for a coal fired power plant with an installed power of 100 MW and considering the CO2 capture process efficiency of 90 %.
Aspects of using biomass as energy source for power generation

Published: August 2017

Abstract
Biomass represents an important source of renewable energy in Romania with about 64% of the whole available green energy. Being a priority for the energy sector worldwide, in our country the development stage is poor compared to solar and wind energy. Biomass power plants offer great horizontal economy development, local and regional economic growth with benefic effects on life standard. The paper presents an analysis on biomass to power conversion solutions compared to fossil fuels using two main processes: combustion and gasification. Beside the heating value, which can be considerably higher for fossil fuels compared to biomass, a big difference between fossil fuels and biomass can be observed in the sulphur content. While the biomass sulphur content is between 0 and approximately 1%, the sulphur content of coal can reach 4%. Using coal in power plants requires important investments in installations of flue gas desulfurization. If limestone is used to reduce SO2 emissions, then additional carbon dioxide moles will be released during the production of CaO from CaCO3. Therefore, fossil fuels not only release a high amount of carbon dioxide through burning, but also through the caption of sulphur dioxide, while biomass is considered CO2 neutral. Biomass is in most of the cases represented by residues, so it is a free fuel compared to fossil fuels. The same power plant can be used even if biomass or fossil fuels is used as a feedstock with small differences. The biomass plant could need a drying system due to high moisture content of the biomass, while the coal plant will need a desulfurization installation of flue gas and additional money will be spent with fuel purchasing.

Abstract
This paper optimizes the price-based demand response of a large customer in a power system with stochastic production and classical fuel-supplied power plants. The implemented method of optimization, under uncertainty, is helpful to model both the utility functions for the consumers and their technical limitations. The consumers exposed to price-based demand can reduce their cost for electricity procurement by modifying their behavior, possibly shifting their consumption during the day to periods with low electricity prices. The demand is considered elastic to electricity price if the consumer is willing and capable to buy various amounts of energy at different price levels, the demand function being represented as purchasing bidding blocks. The demand response is seen also by the scientific literature as a possible source of the needed flexibility of modern power systems, while the flexibility of conventional generation technologies is restricted by technical constraints, such as ramp rates. This paper shows how wind power generation affects short term operation of the electricity system. Fluctuations in the amount of wind power fed into the grid require, without storage capacities, compensating changes in the output of flexible generators or in the consumers’ behavior. In the presented case study, we show the minimization of the overall costs in presence of stochastic wind power production. For highlighting the variability degree of production from renewable sources, four scenarios of production were formulated, with different probabilities of occurrence. The contribution brought by the paper is represented by the optimization model for demand-response of a large customer in a power system with fossil fueled generators and intermittent renewable energy sources. The consumer can reduce the power system costs by modifying his demand. The demand function is represented as purchasing bidding blocks for the possible price forecasted realizations. The consumer benefit function is modelled as a piecewise linear function.

Abstract
Logistics management is one of nowadays tools to face economic challenges; it’s a mix of business and core activities of the organization. The supply and distribution activities integrated together form what’s known as logistics activities. The logistics activities within a business organization attempt to satisfy customers through achieving the time and location related market challenges and also through the cost of the service provided as well as the quality, taking into consideration customers needs and purchase power. Customer satisfaction is important because it provides marketers and business owners with a metric that they can use to manage and improve their businesses. Customer satisfaction is also a way to determinate the continuity of the business or of a product life by measuring the loyalty of the customers. If the customers are happy and satisfied, it will ensure the continuity of sales which means the continuity of the business. In the past customer satisfaction was more focused on requirements such as quality and reliability reducing costs of poor quality. In mid 50’s the production costs were continuously increasing, The way to maintain the company’s position within a changing market and increase profit starts by focusing on the service provided to the customer and on decreasing the cost, logistics activities became the backbone of these organizations that target the customer satisfaction while achieving competitive advantage. This study aims to show the impact of the logistics management on customer satisfaction in small and mid-sized Algerian industrial companies, by interviewing the companies managers and everybody in charge of the logistic process, the interview questions will be based on some literature review issues.

Authors: Suciu Marta-Christina 
Published: August 2017

Abstract
The main goal of the paper is to highlight the importance of supporting the promotion of the culture of excellence among people involved in a way or another in contemporary business. In order to support business excellence, the culture of excellence have to empower and engage all the people within an organization to think out of the box in a modern vision suitable to the challenging and changing times we are facing now. All over the world, in the most competitive countries, regions and sectors of activities there is a paradigmatic change of business strategies and policies oriented more and more towards performance and excellence. The paper highlights the importance of promoting the culture of excellence in the contemporary changing business environment. It suggests an important shift from a perspective that focuses on the so called ‘hero of excellence’ towards promoting the culture of excellence among the whole organization. Within modern business, in order to face challenges of the changing times and to explore their opportunities all the people from an organization are considered to manifest as ‘heroes of excellence’ by co-creating and co-working together within creative and innovative teams. They have to contribute and to participate actively to assure, preserve and develop the competitiveness and well being of the whole organization. The paper supports a holistic, cross disciplinary and integrated vision. It is structured into three parts including: a brief literature review based on an overview of the current state of the literature dedicated to the topic of culture of excellence (part 1); presentation of the main steps of the process of building a sustainable high performance organization (part 2); a brief presentation of examples of best practice and case studied identified internationally (part 3); conclusions that highlight the importance of culture of excellence in changing and challenging times.

Published: August 2017

Abstract
For more than three decades now, famous and relatively famous theoreticians from around the world and from Romania having different specialisations and statuses within society (from economists who work in universities and research centres to those involved in political decisions, from anthropologists to sociologists, from political analysts to jurists) and also practitioners that have transposed their ideas into reality by creating their own small or medium enterprises which support their roles within both the national and international economies. Additionally, statistics, be them undertaken by international organisations such as UNO or the EU or other national institutes reveal the ever increasing share of SMEs within the GDP, employment, turnover and the list may continue. The concern of policy makers of encouraging the development of entrepreneurship is manifested both in the legislative and financial frameworks by granting tax exemptions to those starting a business, by awarding them financing under certain conditions or by fostering the possibility of their accessing various European funds. This article seeks to provide the necessary support to the persons/entities that would or should take the necessary steps in order to define the job of the entrepreneur or undertaker in the economic field in general and not particularly in the construction field making a review of the current entrepreneurial phenomenon in Romania and analysing the opinions of different entrepreneurs with respect to the requirements of the jobs they have. Purposively, we designed and distributed a questionnaire in Bucharest. The number of valid responses is 47 and even if the sample is not representative, we consider the findings a step forward to defining the entrepreneur job.
Human resources challenges for the 21st century
Authors: Rasca Lavinia 
Published: August 2017

Abstract
Researchers predict that, in the next decade, significant changes will dominate the labor market. On the on hand, new jobs will be created by employers, while others will be displaced. The World Economic Forum recently estimated that 65% of the children entering primary school today will work in completely new jobs when they will enter the labor market, while many in-demand occupations or specialties are less than 10 years old. Employers start to have as a major objective to increase labor productivity, and innovation. They look for new skills, that are scarce, willing to attract, engage and retain in their organizations people that demonstrate attitudes like resilience, responsiveness to change, entrepreneurial mindset, willingness to innovate. While corporations, in their attempt to increase productivity, restructure and lay off people, entrepreneurship becomes a hope for a better living. On the other hand, the human resources market will start soon to be dominated by millennials, having to work together with people from X generation, who will retire later or not at all. Women will be more and more present in the labor force, as well as immigrants. All these phenomena will change the characteristics of the working places. In the digital world, the border between the work life and the professional life will become blurred. Wellbeing, meant at enhancing both professional and personal life, will be crucial. HR departments and leaders will have new challenges. In this paper, based on relevant literature review, attempts to identify challenging changes encountered in the labor markets, as well as actions that might improve knowledge, skills, and attitudes, necessary in the present society. Another goal is to create a model depicting the factors and flows that motivate, satisfy, and engage employees. The paper might be of interest for government, educators, training providers, employers, and workers.
Branding post-communist Romania and its effects on country image
Authors: Andrei Anca-Georgiana 
Published: August 2017

AbstractIn recent years, more precisely from 1989 on, which was considered by a lot of experts the beginning of the second stage of globalization, nation branding campaigns have started to be launched in more and more countries in order to help developing nations image and reputation and to provide a competitive edge on economic, social and even political areas. Simon Anholt and Wally Olins are the two authors who studied the most nation branding phenomenon and came up with theories which were applied often by professionals when elaborating nation branding campaigns for different states. Nadia Kaneva, Keith Dinnie, Melissa Aronczyk, Luminita Nicolescu and Alina Dolea have also focused their researches on this theme and manage to contribute with new and interesting ideas to the field. This paper provides insight into the most important nation branding campaigns made by Romania starting from 1989 until present. Through a comparative analysis of those campaigns the paper tries to identify which was their impact on Romania’s image or reputation. How was Romania perceived (from the image perspective) before 1989 at international level? Did the image change after 1989? And what was the impact of the most important branding nation campaigns implemented after 1989 in the image of Romania and implicit in economy? These are the main questions this paper tries to answer. At the same time, the study also explores briefly the concept of globalization, nation branding, national image and national reputation. The conclusions of the paper will provide in the end a general background of all studied nation branding campaigns which will include the similarities and differences between them, but also both strong and weak points. Its aim is to contribute, among other existing papers, as a starting point for researchers or professionals who want to elaborate nation branding strategies for Romania or other countries.
Involvement of small and medium-sized enterprises (SMEs) in elaborating and implementing public policies: Study case-Romanian small and medium-sized enterprises
Authors: Popescu Ruxandra , Ghiocanu Stefania 
Published: August 2017

AbstractInvolvement and development of the private sector in boosting the economy nationwide is a main objective of the current program of the government, which means that a good cooperation between small and medium companies, private companies and multinationals and public environment including both public institutions and policies implemented and developed by them, becomes more than necessary. The paper summarizes the findings of a quantitative research based on a self-applied questionnaire which was aimed at Romanian small and medium-sized enterprises and also of a qualitative research that gives an overview of the process of elaborating and implementing a public policy. The involvement of small and medium-sized enterprises in the process of designing and implementing a public policy can become indispensable but it is well know that there is, in fact, a lack of initiative at this level, from both parties. One of the main research questions of this paper is to find out how much do representatives of small and medium-sized enterprises get involved in the process of elaborating a public policy and how much do these actions and measures impact the organizational policies of the companies themselves. A good cooperation between the business environment and the public institutions and a strong correlation of their joint efforts, should become a common practice between both parties, being crucial that this form of cooperation to be initiated from the very beginning. The contribution of this paper is a practical one, given the fact that the paper itself entails the direct responses of small and medium-sized enterprises on the current and future public policies that directly targets them, providing as well an analysis on the effects of public policies on small and medium-sized enterprises. Thus being said, the paper can also be a guide for both small and medium-sized enterprises in providing examples and measures of involvement and favorable public policies development, but also for public institutions by analyzing responses based on practice activities of small and medium-sized enterprises; giving them a solution to correct or continue generating positive results of those policies.

Published: August 2017

AbstractThe paper plans to analyze the evolution and structure of trade of the Republic of Moldova between 2005 and 2015, its weight correlated with that of other important trade partners and its potential for development. In the first part we will make a comparative analysis between the overall exports and imports of Moldova towards the EU and CIS, also from a perspective of evolution and structure. We want to see the main categories of products that are exported from Moldova and also the main products that are imported and how this trade changed according to the legislation. We shall also develop an index of dependency of Moldova towards these economic zones and its evolution. In the second part we shall focus on the structure and evolution of trade of Moldova with The Russian Federation and Ukraine in order to analyze their weight but also the degree of economic cooperation between the countries. We are also interested to see which are the most important categories of products, that are traded between these countries and how were they affected by the relation of Moldova with the EU. In the third part we will analyze the overall trade of Moldova with Romania, measuring the evolution of the weight of Romanian exports and imports from and towards Moldova and the changes in their structure. An objective will be to set a theoretical optimum level of development in order to set a level of trade which could support a strong and sustainable economic development between the two countries.
