The pedagogical thought and concept of the system of protection by Edmund Bojanowski’s upbringing, even though it was born 170 years ago, appears today to be innovative and exceptionally up-to-date. Applied in contemporary pre-school education and child care, it is a continuation of the concept of upbringing and its practical implementation by establishing on May 3, 1850 the nursery and Congregation of the Servant Sisters. The theoretical and practical application of this concept and new research and scientific studies on the essence of early education realized in Catholic pedagogical thought in the context of contemporary civilization challenges is still expected from various circles in Poland and worldwide.

Finite Planning Horizon

Abstract This paper describes the optimization of preventive maintenance (PM) over a finite planning horizon in a semi-Markov framework. In this framework, the asset may be operating, and providing income for the asset owner, or not operating and undergoing PM, or not operating and undergoing corrective maintenance following failure. PM is triggered when the asset has been operating for τ time units. A number m of transitions specifies the finite horizon. This system is described with a set of recurrence relations, and their z-transform is used to determine the value of τ that maximizes the average accumulated reward over the horizon. We study under what conditions a solution can be found, and for those specific cases the solution τ* is calculated. Despite the complexity of the mathematical solution, the result obtained allows the analyst to provide a quick and easy-to-use tool for practical application in many real-world cases. To demonstrate this, the method has been implemented for a case study, and its accuracy and practical implementation were tested using Monte Carlo simulation and direct calculation.

Significantly revised and updated, the new Model Child Care Health Policies, 5th Edition is a must-have tool to foster adoption and implemenation of best practices for health and safety in group care settings for young children. These settings include early care and education as well as before and after school child care programs. These model policies are intended to ease the burden of writing site-specific health and safety policies from scratch. They cover a wide range of aspects of operation of early education and child care programs. Child care programs of any type can use Model Child Care Health Policies by selecting relevant issues for their operation and modifying the wording to make selected policies appropriate to the specific settings. These settings include early education and child care centers, small and large family child care homes, part day-programs for ill children, facilities that serve children with special needs, school-age child care facilities, and drop-in facilities. The model policies can be adapted for public, private, Head Start, and tuition-funded facilities. All of the most commonly covered health and safety topics the National Association of Child Care Resource and Referral Agencies found in state regulations are included in this guide.

Abstract. The main purpose of this article is to review the theoretical prerequisites of nuclear magnetic resonance (NMR) application in tasks of search and exploration of hydrocarbon deposits. The identification peculiarities of hydrocarbon deposits in a weak magnetic field of the Earth were analysed. The necessity of using highly directional antennas for providing greater sounding depths as well as the use of absorption spectra of the sought-for minerals as sounding signals were identified and justified. A variant of practical implementation of such a system was examined and examples of practical application of the innovative NMR technology were provided.

The human species transforms the landscape to meet its needs, but landscape resources and valuable features at the same time affect wellbeing in the context of human activity. In these mutually conditioned interactions, two processes playing a key role are the so-called landscape perception and landscape projection. This article presents: (1) a review of theories playing a key role in the development of knowledge on landscape perception; (2) the basis for landscape projection as a logical and creative continuation of perception processes; (3) an outline of the theory of physiognomic landscape structure and of possibilities for it to gain practical application; (4) the results of the first Polish research into the public’s expectations where quality of the landscape is concerned. Perception of the landscape entails the receipt of stimuli from surrounding space with the help of the senses. It serves primarily in knowledge-based transformation of landscape systems, in a manner that meets ever-more exacting requirements on the part of society when it comes to living in an environment of the highest quality. Only a little scientific work has been devoted to the process of landscape projection. This is therefore a new research field, just opening up, which has the potential to give rise to a group of space-projection theories.

AbstractRecently most of the Gulf countries have had significant urban development, with innovative architecture, as a result of the production of Liquefied Natural Gas (LNG) in many places in the world. This has generated an unprecedented construction boom in the cities and the surrounding areas.Despite their rather short urban history, the Gulf States have recently launched several signatures mega-projects, where public investments are developing an urban structure of a global dimension. Affecting the direction of the rapid urbanization is a permanent tension between the creation of a new, modern cultural identity and the promotion of traditional architecture. One aim is to establish new connections with local history and cultural traditions.To reveal the challenge of the construction of a new architectural identity in the Arab emerging cities, this paper focuses on the action needed to preserve historical, cultural, traditional, and architectural heritage, with the aim of filling the gaps of knowledge and encouraging new research in the fields of restoration and conservation that will lead to future practical implementation.The paper also calls for a fresh look at the tradition, modernity, and identity, by outlining a number of aspects related to the current status of architectural heritage conservation in some Arab cities. Traditional culture, ancient architectural constructions, and vernacular architecture are the result of historical processes and products of Arab societies. Understanding this is an indispensable tool for the comprehension of the Arab modern cities, a knowledge which can influence their future expansion and revitalization, and the shaping of a new architectural identity in these areas. In the Arab regions, restoration methodologies also need to be defined and implemented with the aim of preserving cultural heritage and raising the conservation and restoration research profile among the international research community.

Aromatic voltage stabilizers can improve the dielectric properties of cross-linked polyethylene (XLPE); however, their poor compatibility with XLPE hinders their practical application. Improving the compatibility of aromatic voltage stabilizers with XLPE has, therefore, become a new research goal. Herein 1-(4-vinyloxy)phenylethenone (VPE) was prepared and characterized. It can be grafted onto polyethylene molecules during the cross-linking processes to promote stability of the aromatic voltage stabilizers in XLPE. Fourier transform infrared spectroscopy confirmed that VPE was successfully grafted onto XLPE, and effectively inhibited thermal migration. Thermogravimetric analysis showed that the grafted VPE/XLPE composite exhibits a better thermal stability than a VPE/PE blend composite. Evaluation of the electrical properties showed that the breakdown strength and electrical tree initiation voltage of the VPE/XLPE composite were increased by 15.5% and 39.6%, respectively, when compared to those of bare XLPE. After thermal aging, the breakdown strength and electrical tree initiation voltage of the VPE/XLPE composite were increased by 9.4% and 25.8%, respectively, in comparison to those of bare XLPE, which indicates that the grafted voltage stabilizer can effectively inhibit its migration and enhance the stability of the composite material.
