Authors: Knapinski Marcin , Bobarikin Yuri L. , Radkin Yaroslav I. 
Published: December 2019

Abstract
Increasing the accuracy of the geometrical parameters of tube profiles is one of the priority areas of modern tube industry. The profile of the calibers of rolls of the reeling mill exerts a significant influence over the distribution of stresses that appear in metal during the deformation process and the process of formation of the correct geometry of the obtained rough tube. The method for determining the optimal geometry of a mill roll profile has been developed. In accordance with this method the geometry of the calibers of the continuous three roll reeling mill was calculated. The research of the influence of geometrical parameters of the calibers of mill rolls on the accuracy of the obtained tube profile, the load of the rolling tool and the wear rate of the contact surface of mill rolls and a mandrel was carried out. The numerical simulation method was chosen as a research method. This method allows to carry out rather accurate analysis and to obtain reliable results on the stress-strain and thermal states of a billet during the material processing, gives the possibility to obtain numerical values of stresses, deformations, load parameters of the process, as well as allows to visualize the results that is essential for assessing the accuracy of the tube profile geometry. Numerical experiments of the elongating process of a rough tube on the three roll continuous reeling mill with different grooving of mill rolls were carried out. It was determined that using of the developed grooving will allow to get a rough tube of a higher accuracy with the minimal deviation from the shape of the profile. The use of the developed method of calculating the geometric parameters of the calibers of the continuous reeling mill will allow to obtain calibers with a high degree of resistance to wear due to the reduction of the resistance of the flow of metal and a uniform filling of the calibers in the deformation zone. The use of this grooving of mill rolls will reduce the load acting on the rolling tool during the production of hot-deformed seamless tubes.

The paper present the statutory definition of an accident at work and its basic categories (light, heavy, mortal and collective accident). It also discusses the most popular accident investigation method – the TOL method, which classifies the causes of accidents into three basic groups: material-technical, organizational and human. In the further part of the work the characteristics of the waterjet operator’s work station were made, including the scope of activities, possible occupational hazards and preventive actions. Next, the results of the analysis of the circumstances and causes of accidents at work were presented. In the period from 2013 to 2018 eight accidents were reported, resulting in minor injuries, such as cuts and cuts, fracture of the phalanx, overloading of the spine, leg twisting or knee injury.
Food Safety as a Key Factor in the Supply Chain
Authors: Szymonik Andrzej , Chudzik Daniel 
Published: December 2019

Abstract
Food production system, due to the mass scale of its manufacturing, distribution, and consumption, is subject to rigorous protection and control. The analysis of food safety presented in the foregoing publication shows that legal and organizational regulations are not alone sufficient to ensure that the quality of products does not pose a health and environmental threat. The results of the study conducted with the participation of 15 subjects make it evident that the issue of food safety is complex and requires continual monitoring because of ever changing conditions. It is increasingly seen that food safety is a key factor in supply chains, becoming the overriding element of production systems. Production companies spend more and more money on control and modernization of the entire production-related system so that food safety is 100% guaranteed. In the last few years, it can be seen that audits in manufacturing companies that deal with the production and sale of food are largely focused on food safety, process monitoring systems and employee access controls to individual production zones. Not without significance is the fact that additional departments are created in manufacturing companies, whose main task is to control production processes in terms of food safety, both from the side of the safe use of raw materials, packaging and the interference of unauthorized persons. It is absolutely necessary to emphasize that the paper also shows some examples that can already be treated as the first symptoms of food terrorism, which is becoming a deadly tool for current and future food terrorists. The publication emphasizes that food safety in the market reality of that time may be of paramount importance in the supply chains, given the importance and consequences of possible mass contamination of food.

Published: December 2019

Abstract
This study’s purpose was to investigate any possible relationship between the goal perspectives (task and ego orientation) and volitional competences (persistence, expedience, and purposefulness) in physical activities settings. Participants were 134 people with a physical disability (103 men and 31 women) with age ranging from 14 to 67 years. All participants participated in physical activities. Participants filled out the Measure Athletes’ Volition – Short (MAV-S), and Task and Ego Orientation in Sports Questionnaire (TEOSQ). Results revealed that volitional competencies are predictors goal perspectives in physical activity settings. In addition, the findings showed that the expedience is a stronger predictor to task orientation, while persistence competence is to ego orientation. In conclusion, the present study is considered to offer new knowledge on the achievement goal orientation people with physical disabilities in physical activity contexts. The first one is that volitional competencies (expedience and purposefulness) are significantly positive predictors of task orientation. The second conclusion is that persistence competence is significantly positive predictor, while purposefulness competence is negative predictor of ego orientation.
A Comparative Study of Leisure Constraints in Outdoor Leisure Activities Depending on Recognition of the Level of Particulate Matter (PM10): Focused on Golf Participants in the Republic of Korea
Authors: Choi Chulhwan , Bum Chul-Ho 
Published: December 2019

Abstract
Particulate matter, one of the most recent social problems in Korea, not only poses a threat to people’s health, but is also emerging as a constraint to discourage outdoor leisure activities. Golf, a leisure sport played outdoors for hours, is not free from such a threat, and now is time to analyze golfers’ recognition of particulate matter. To examine whether particulate matter, among other constraints for golfers, had a significant effect as well as how golfers recognized particulate matter, we used 324 collected questionnaires in this study. After exploratory factor analysis and reliability analysis through SPSS 23.0, we divided questionnaire participants into recognition and non-recognition groups based on whether they checked and recognized atmospheric conditions, including particulate matter, before playing golf, and used multivariate analysis of variance (MANOVA) to compare and analyze leisure constraints. Respondents in the recognition group who recognized particulate matter in advance experienced participation constraints in weather and health factors, while those in the non-recognition group experienced participation constraints in skill and confidence factors. In other words, respondents participated in outdoor leisure activities even though they recognized the level of hazardous particulate matter in the air beforehand, and particulate matter worked as a participation constraint for them; this finding confirmed that it will be necessary in the future to take preventative action more actively against the danger of particulate matter.

Published: December 2019

Abstract
The Portuguese automotive industry is a relevant activity sector for the Portuguese society and economy, both in job creation and value-added generation, contributing to the country’s economic development. The automotive is a high challenge industry, with intense competition, a high number of brands, increased number of models and vehicles, tighter regulatory requirements (e.g., emissions), and the need to manage global supplier networks. To succeed in such a highly complex and interconnected industry requires firms to be globally competitive since most of the production of this industry is destined for the rest of the world through export. This research aims to investigate the factors that contribute to value creation and competitiveness of the Portuguese automotive industry. Following the literature review of competitive advantage theories, quantitative research was done through an online questionnaire with Portuguese auto industry firms, to validate the proposed research hypotheses. The statistical analysis of the results, based on the application of descriptive statistics methodologies, principal components analysis, and correlation analysis, allowed to conclude that in this industry sector, the adoption of a strategy of differentiation/focalization and the external context influence value creation. However, it was not possible to conclude if the specific characteristics of the organization influences, or not, the creation of value. From the theoretical point of view, the conclusions demonstrate the relevance of the adoption of a strategy of differentiation and focalization and the external context for the competitiveness of these firms, supporting the assumptions of Porter’s Industry Based Theory and Generic strategies. From the practical point of view, the results highlight the importance of monitoring the external context and investing in research and development, brand image and market expertise, with the aim of enhancing the value creation and competitiveness of the components, tools, and services providers firms of the Portuguese automotive sector.

Published: December 2019

Abstract
The commercial sector and especially the food trade in Romania have expanded more and more through the medium of hypermarkets-supermarkets, online commerce, etc. thus dominating the market. The turnover and profit they make are significantly increasing, while small and medium-sized businesses in stores and traditional stores lose customers, their market share is diminishing, profitability is low, and they are confronted with big financial problems. Modern trade tends represent almost 60% of Romania’s total market, which means that small shops are losing ground in detriment of others, despite their currently large number at national level. The study, extended over a period of more than 5 years, includes a comparative analysis of the small and medium-sized enterprises in the food commerce sector of Cluj County and the supermarkets-hypermarkets in Romania. Advantages of hypermarkets - supermarkets, online commerce, etc. in relation to small and medium-sized stores are ultimately reflected in the financial performance. Following the selection of 5 financial indicators, considered by the authors to be representative of the trade sector, and their comparative analysis, one can see the economic and financial situation these small and medium retail companies are facing, if they do not change their strategy. Their disappearance from the Romanian market would result in social and economic consequences and the discontent of a segment of the population.

Abstract
In recent years area of entrepreneurship has gained significant attention nationally and internationally. It is one of the main skills priorities of national governments and EU council. Traditionally associated with commercial activity, entrepreneurship has gained traction as a key competence necessary to allow society as a whole to adapt to the changing economic climate. Small and medium sized companies (SMEs) greatly contribute to employment and wealth in Europe but there are limited studies into the specific skills needs required for SMEs into the future. Skills such as problem solving, critical thinking and entrepreneurship allow learners to adapt to changes, communication, digital skills and teamwork allow learners to collaborate and exploit technology in the changing workplace. Research is a key element of entrepreneurial success, but how these skills particularly workplace-oriented ones improve entrepreneurial culture has not been widely explored in the literature. This paper explores the importance of entrepreneurship today, the skills required to allow our society to become more entrepreneurial and identifies the potential of workplace research skills to develop entrepreneurial capacity in all facets of work, particularly within SMEs. The authors collaborated on many European projects aimed at improving work and education/training of entrepreneurs. The work presented int this paper resulted from surveys conducted within these projects regarding the problems SME staff have in connection with workplace transformation and entrepreneurship education and training. From this the paper proposes a conceptual model to facilitate the development of workplace research skills which will enhance entrepreneurial capacity in SMEs. The problems discussed in this chapter will also be used within the German initiative Mittelstand 4.0-Kompetenzzentrum with the participation of one author. Companies within this program are eager to improve their workplace research skills and change the learning culture and staff behavior in connection with digital workplaces.
Stress and scenario tests in the context of a Romanian non-life insurance company
Authors: Dina Manolache Aurora Elena 
Published: December 2019

Abstract
The main aim of the article is to assess the vulnerabilities and resilience of a Romanian non-life insurance company in the context of different predefined insurance stress scenarios: natural catastrophe scenario and business scenario. The natural catastrophe scenario consists in two distinct scenarios: earthquake and flood, which were carried out separately and aggregated based on three stress factors: increasing by 15% of PML, increasing by 5% of the gross best estimate claim provisions and reinsurer’s incapacity to pay. The business stress scenario was based on four stress parameters: increasing by 3 % of the claims provisions due to the inflation impact, increasing by 10% of the gross earned premium for MTPL due to the legislative changes, increasing by 15% of the claims provisions for MTPL due to the increase of frequency and severity of the losses induced by the exposure growth as a result of the lower premiums and decreasing by 10% of the ceded best estimate. The results of the stress testing shown that the insurer is more sensitive to business scenario compared to natural catastrophe scenario due to the significant exposure on the MTPL line of business. High exposure to earthquake risk is a characteristic for Romania and the stress testing results confirm the vulnerability of the insurer to the earthquake scenario (non-compliance of the solvency capital requirements), due to the biggest impact of the factor: reinsurer’s incapacity to pay. Therefore, the quality of reinsurance is very important for Romanian insurance companies to be able to manage the risks arising from the seismic events and to be compliant with the regulatory solvency capital requirements.
Operational risk assessment at investment funds level
Authors: Baranga Laurentiu Paul 
Published: December 2019

Abstract
The operational risk has been analysed quite recently, both by the academic environment and by financial entities in their practical activity. This new risk has recently been introduced into the “solvency models” provided by the Capital Requirement and Solvency legislation. The “solvency models” are absolute assessment models and are based on the idea of determining an optimal solvency ratio between the level of potential losses associated with the risks a financial entity is exposed to and the level of own funds it holds. Below this optimal ratio it is considered that, in the event of a materialization of the risk, the entity will go bankrupt. In the financial industry there is also a category of financial entities that legally cannot go bankrupt, at worst they may be affected by a galloping decapitalization. This category includes investment and pension funds. Due to the fact that investment and pension funds are managed externally, the operational risk originates at the level of the manager and produces its effects on the assets held by the fund, namely on the unit value of the net asset or on the value of the net asset in case of decapitalization. In order to assess the operational risk of the funds, different approaches to Capital Requirement and Solvency should be applied. In this respect, the classification of funds according to the level of risk to which they are exposed can be done through relative assessment models, and the determination of the loss amount caused by the operational risk can be done by indirect methods. Such relative risk assessment models can also be used by financial/non-financial entities that have legal personality, as a mechanism for controlling absolute assessment models, or as a stand-alone assessment methodology if there is no regulated methodology.
