The current industrial constraints on production systems, especially availability problems

are complicating maintenance managers’ mission and making longer and further performance

improvement process. Dealing with these problems in a wiser managerial vision respecting

sustainability dimensions would be more efficient to optimize all resources. In this paper, and

after addressing the lean/sustainability challenge in a the literature to define main research

orientations and critical points in manufacturing and then maintenance specific context, two

case studies have been conducted in two production systems in Morocco and Canada, within

the objective to set a clearer scene of the lean philosophy implementation in maintenance

and within the sustainability scope from an empirical perspective. To activate the social dimension

being often non-integrated in the lean/sustainability initiatives, the article authors

reveal an original research direction assigning maintenance logistics as the leading part of our

approach to cover all sustainability dimensions. Furthermore, its management is discussed

for the first time in a sustainable framework, where the authors propose a new model considering

the lean/sustainable perspective and inspired by the rich Human-Machine interaction

memory to solve daily maintenance problems exploiting the operators’ experience feedback.

Research focused on integration of machine operators with information flow in manufacturing process according to Industry 4.0 requirements are presented in this paper. A special IT system connecting together machine operators, machine control, process and machine monitoring with companywide IT systems is developed. It is an answer on manufacture of airplane industry requirements. The main aim of the system presented in the article is full automation of information flow between a management level represented by Integrated Management IT System and manufacturing process level. From the management level an information about particular orders are taken, back an on-line information about manufacturing process and manufactured parts are given. System allows automatic identification of tasks for machine operator and particular currently machined part. Operator can verify information about process and tasks. System allows on-line analyzing process data. It is based on information from machining acquired: machine operator, process and machine monitoring systems and measurement devices handled by operator. Process data is integrated with related order as a history of particular manufactured part. System allows for measurement data analysis based on Statistical Process Control algorithm dedicated for short batches. It supports operator in process control. Measurement data are integrated with order data as a part of history of manufactured product. Finally a conception of Cyber-Physical Systems applying in integrated Shop Floor Control and Monitoring systems is presented and discussed.

The death of a person, particularly my own death, is the most momentous occasion that happens in a lifetime. It seems to be an inevitable end of any possible experience, ceasing any relationship, the end of memories and hopes. It evokes various reactions in the living, just to mention some as: fascination, fear, stress, consent, willingness to familiarization. Each of them may be analysed, while each one shows also the death in a different aspect. In the proposed article, the author indicates another reaction - that is experiencing anxiety. It appears that this is the key experience, both when I am thinking about it as something that may afflict me at any moment, as well as when I become aware that there is a possibility of exit of the loved ones or just a popular person. Some texts by Joseph Ratzinger have inspired me to carry out such analyses.

This article describes security mechanisms used by 3rd-7th layers in OSI/ISO network model. Many of commonly used protocols by these layers were designed with assumption that there are nointruders. Such assumption was true many years ago. The network situation has been changed for last few years and we should realize that some properties of existing protocols may be abused. Moreover, we should exchange some of them or create new versions. There are some methods and guidelines concerning secure programming, but there is also lack of guidelines about creating secure protocols. Authors see the necessity of such guideline and this article is an attempt at analysing existing solutions and selecting some universal and important patterns.

The author presents the concept of man in the philosophy of Erich Fromm. The article consists of two parts. In the first part, the author presents how Fromm characterised the existential situation of man; in the second part he describes love as the main factor in the action and development of a human being. Man is part of nature, subjected to the rules of its laws, but he also transcends nature by the ability to use mind. A human subject is aware of his/her limitations and weaknesses with regard to nature. He/she feels lost and lonely in relation to other people and the natural world. Therefore, s/he looks for the frame of orientation and references. This search is the most important existential problem. Love is the solution to all problems of human existence. According to Fromm, man is the subject of love.

The topic „The Bible and Christian Morality" was thoroughly studied by the Papal Biblical Commission. The article's author presents the originality of this concept. He proves why we ought to speak of „revealed morality" and not about Gospel ethics, the writings of St. Paul or OT and NT ethics. Morality - as opposed to ethics - does not rely on freely accepted initial assumptions, but is man's response to the gifts received from God: creation, covenant and fullness of revelation in Christ. It brings to light the criteria resulting from the Bible itself, which contemporary Christians should apply when dealing with problems that contemporary sciences, techniques and culture present, but about which the inspired books do not directly speak of. He stresses that the Bible itself, revealing what is unique and which does not undergo discussion, at the same time calls the faithful of God to dialogue with the world in which we live, particularly with believers of other religions.

The paper considers the vision of the world and the person of Józef Kazimierz Plebański (1831–1897), the Warsaw historian, one of two Polish students of Leopold von Ranke. In my article, I analyse the essential categories and objects which structure his thinking about reality, such as liberty, Providence, moral laws, state, nation, and humanity. At the end, I try to compare the worldview of Plebański with the worldview of historicism.

Business ethics is a complex issue that has been studied a lot. This paper discusses just one of its aspects and presents the assumptions of ethics of economic activity arising from Christian anthropology. They include respect for the dignity of the human person, taking into consideration the social dimension of human life and the affrmation of man’s integral development. All those are particulars of the general principle that man is the creator, the centre and the goal of the whole life and economic activity. These assumptions are in no way unrealistic and idealized expectations in relation to economic and business activity, they rather prove that the economic sphere of life is not ethically neutral, neither is it inhuman nor antisocial. As a dimension of man’s activity it is subject to a moral assessment. Since all stages of economic activity deal with man, his behaviour and needs, they involve moral implications. Even if in certain circumstances unethical behaviour may lead, though temporarily, to economic success, the economic and moral facets are intertwined. J. Messner was right when he stressed that in one’s striving for economic goals immoral means are at the same time uneconomic. The present fnancial and economic crisis proves his thesis.

The present study was aimed to establish a novel TaqMan real-time PCR (RTm-PCR) for detecting and typing bovine viral diarrhea virus (BVDV), and also to develop a diagnostic proto- col which simplifies sample collection and processing. Universal primers and TaqMan-MGB probes were designed from the known sequences of conserved 5′ - and 3′-untranslated regions (5’UTR, 3’UTR) of the NADL strain of BVDV. Prior to optimizing the assay, cDNAs were tran- scribed in vitro to make standard curves. The sensitivity, specificity and stability (reproducibility) were evaluated. The RTm-PCR was tested on the 312 feces specimens collected from persistently infected (PI) calves. The results showed the optimum conditions for RTm-PCR were 17.0 μmol/L primer, 7.5 μmol/L probe and 51.4°C annealing temperature. The established TaqMan RTm-PCR assay could specially detect BVDV without detecting any other viruses. Its detection limit was 1.55×100 copies/μL for viral RNA. It was 10000-fold higher than conventional PCR with excel- lent specificity and reproducibility. 312 samples were tested using this method and universal PCR from six dairy farms, respectively. Positive detections were found in 49 and 44 feces samples, respectively. The occurrence rate was 89.80%. In conclusion, the established TaqMan RTm-PCR could rapidly detect BVDV and effectively identify PI cattle. The detection limit of RTm-PCR was 1.55 copies/μL. It will be beneficial for enhancing diagnosis and therapy efficacy and reduce losses in cattle farms.

This article talks about a famous novel by Leopold Tyrmand entitled Zły (The Bad) which was translated into English by David Welsh as The Man with White Eyes (New York: Knopf, 1959). The author claims that the novel which describes a life in destroyed Warsaw of the 1950s gradually became an epic. The author refers to a conception by Polish literary scholar and critic Kazimierz Wyka who claimed that epics are not written, but – under some circumstances, sometimes even against the will of the writers – some texts become epics. According to the author, in Zły (both in the style and in the plot) can be found the elements of brilliant epic stylization. The novel which at first was read as a thriller gradually became an epic because it described with epic accuracy a world that had disappeared, a world where a new life was born in the ruins.

On 24th March, 2017 Professor Józef Kozielecki passed away. He was a world renowned psychologist, a researcher into cognitive processes: thinking, problem solving, decision making. Professor Kozielecki was an author of the psychological theory of decision making, the theory of self-knowledge, and a founding father of the new direction in psychology, psychotransgressionism. An outstanding scholar, intellectual, theacher and a formative mentor for several generations of psychologists. He authored multiple important psychological monographs, for which he received national and international awards, for example, The Japanese Science Foundation award (1980) for his work on decision theory and The Jurzykowski Cultural Foundation award (1990) for his transgressive model of human beings. Professor Józef Kozielecki was a member of several prominent scientific societies such as the European Association of Experimental Social Psychology, the Society for Judgment and Decision making and the European Society for Cognitive Psychology. He was also an Ordinary Member of the Polish Academy of Sciences and in 2007 he received the honoris causa doctorate from the Catholic University of Lublin.
