The Romanian philately, since its inception, has made known to the world the elements of local architecture (traditional and modern), which we place as the foundation of the ecological house concept. Through this paper, we want to present to the public a series of philatelic programs that have as their foreground the traditional architecture enshrined in more than a century, from 1906 to 2016 - including pavilions and pens, peasant houses and palaces, and other architectural monuments.</jats:p>

Soil is also one of the most complex natural systems on the globe. As a result, the community should place a high priority on soil protection because the conservation of soil resources now more than ever calls for legal implementation. The main provisions of the Acquis Communautaire (directives, strategies, decisions, and orders of the relevant ministry, etc.), which come to ensure an interface between the current use of soils, agronomy, and their protection for future generations, are noted in this paper as we propose to analyze the protection of soils from the perspective of the legislation of the European Union and Romania. The scientific approach used only yielded the correlation between EU and national legislation, which was also shown graphically in the form...

There is talk of a utilitarian architecture, which possesses interest and beauty, and which retains in the contemporary memory of the history of society. At the same time, it is unworthy of human heritage if this traditional harmony is not preserved, which is, in fact, the core of the human experience. In this context, the purpose of this study is to emphasize the beauty of traditional Romanian architecture in terms of philately. We want to expose the architectural specifics of three areas - Audia (Neamț), Bancu (Harghita), and Berbești (Maramureș) using postage stamps, illustrated postcards and other philatelic effects.

The first of the challenges is given by the fact that classical education, but also the online one, has become an activity, still unstructured, concerning movements, decisions, and political pressures, implicitly with the changes that occurred in the ministerial apparatus. The second challenge is given by the methodological changes and of the school curriculum, which comes as a completion of the first challenge, being felt even in the teaching-learning-evaluation specific to geometry. The third challenge is given by the weight that teachers face in making geometry a discipline that appeals to students, attractive. In this sense, the challenge for us is to show that this triple barrier can be overcome. As such, the present study proposes a mixed method of presenting the geometric contents in the classroom for the pr...

The game itself can take various forms, sometimes the most interesting. The present paper seeks to present such a form. Starting from education through play, the paper aims to outline another possible dimension of the way of conducting the act of teaching-learning assessment and obtaining feedback. Thus through a series of worksheets, education through play is punctuated and finely delimited, as a bridge between mobile applications and philately. A series of exercises are proposed, which can be carried out in the mixed work variant. They can successfully provide lessons involving fun math or ecology, but the range of uses can be expanded. They can be used as materials in teaching new knowledge and in evaluating existing ones. This study certi...

In this approach, stamps, semi-illustrated and illustrated postcards, maximum postcards and other philatelic effects were used. All this was identified, indexed, analyzed, and described in terms of information provided by philatelic catalogs and sites with dedicated content (such as Colnect®, Delcampe®, PicClick®, and StampWorld®). Following the analysis of the identified pieces, it can be concluded that the respective areas (Stănești, Straja, Șuici, Șurdești and Tilișca) are well delimited from a philatelic point of view, both the exterior and the interior are very carefully represented.

In this context, this study aims to emphasize the beauty and uniqueness of traditional architecture in terms of the tools offered by Romanian philately. Knowing that philately is an ambassador of promoting Romanian cultural values locally, but also abroad, the present study tried to outline this aspect in relation to the ethnographic and architectural specifics. Thus, the architectural specificity of three areas is desired, this time from the localities of Chiojdu Mic (Buzău), Curteni (Vaslui), and Curtișoara (Gorj), using stamps, illustrated postcards, and other philatelic effects. The results of the investigation, carried out through the consultation of sites with predominantly philatelic c...

For the civilized world, however, the hunting activity made huge leaps of content, manifestation, and attitude, eventually reaching to be defined as a cultural, educational, recreational, sports, and even art activity. The present paper has as a subject the national hunting fund, having as a case study, the hunting fund of Maramureș county, specifically, the Vișeu district. We presented the national situation regarding the hunting fund, and only later, after reviewing the definition and characteristics of hunting, we started to present the data for Vișeu district hunting fund, noting that it has a significant hunting potential supported by sustainable management that may still involve adjustment, improvements, and assignment of methodologies, strategies and good environmental practices.

One of the activities in question is hunting. Therefore, continuing the extensive project to promote protected natural heritage and biodiversity, we decided to focus this time on the hunting act and its pure artistic interpretations, introducing the idea of hunting associated with philately. In this sense, the first topic addressed is the first issue of Romanian postage stamps dedicated exclusively to hunting, which appeared at the beginning of 1956. Since then and until now, at the beginning of 2021, philately has been constantly enriched with issues between the most interesting and unique at the same time. The aim of this paper is to make known to the public and to promote nationally and internationally the term sustainable hunting, as an alarm signal for the deplorable state in which game species are tr...

In the transition from classical to modern, through multimedia technologies, the interactions based on the teaching-learning-assessment activity are severely widowed by the physical lack of those closely involved in the educational system. In such a context, considered to be still cloudy, unsettled, the level of perception of those trained is questioned. Thus, through this study, our emphasis and attention fall on how online education is received, accepted, or not among Romanian students; for the study being interviewed only the students from the third year of study, from various specializations (technical and non-technical), aged over 21-22 years. This study took place between November 2020 and February 2021, on a sample of 463 students. Only students with whom the teachers had contact, wh...

Berries, for example, are still an important source of food, being of real use in defining a healthy diet, as well as in natural medicine. But does blueberry have other roles at the community level? Can the blueberry be viewed from another perspective?Here are some questions we aim to answer. In this context, to show that there have been and still are concerns regarding the highlighting of the role of berries in the community, the present study is proposed to analyze their entire Romanian philatelic history. As such, the first approach is limited to the philatelic appearances of the blueberry (postage stamps, “first day of issue” envelopes, maximum postcards, occasional envelopes), appearances identified within the various platforms with philatelic content. The identified philatelic pieces for the reference period 1964-2020, show that there have been and are concerns for the promotion of a healthy diet, a di...

Marine protected areas, in particular, delimited as areas where the main purpose is the protection of nature and cultural values, are important for all segments of society. Through this paper, we aimed to review several aspects, ecological and philatelic alike, regarding the specific biodiversity of the Black Sea ecosystem. Following the analyzes performed on account of the data from the consulted specialized literature (in the form of postage stamps, FDCs, occasional envelopes, and maximum postcards, but also other philatelic effects), as well as as a result of other observations (with catalogs and sites with philatelic content), we concluded that the biodiversity of th...

It is considered a dwelling, the construction consisting of one or more living rooms, with the related outbuildings, the necessary endowments, and utilities that form a common body with the construction, the residential destination and that satisfies the living requirements of a person or family. To successfully design and decorate a house, we need a vision - an image in the mind's eye of the happiest place imaginable. By adding things that make our home as relaxing as possible and removing everything that causes stress, we can explore and develop our ideas. This is how, most of the time, and especially lately, the trend in terms of designing and arranging the house is left within reach of the online environment, especially at the disposal of cinema. The latter has in many cases come to provide new information on the design of housing, but mainly to g...

The words that best describe the essence of Romania are authentic, natural, and cultural, being a country rich in history, art, and natural beauty. As a part of Europe, Romania has often earned its reputation as a country with special cultural and spiritual values. Most often, however, it has been noted in terms of people who have sanctified the places, in terms of places and monuments that delight our eyes, but especially in terms of biodiversity in protected areas recognized nationally and internationally. The purpose of this study is to present the implications of philately in promoting Romania abroad. In this sense, an attempt was made to expose a series of different philatelic effects. The pieces in question (postage stamps, First Day Covers - FDCs, maximum postcards, special envelopes and covers, etc.) that appeared on the occasion of various philateli...

Hugged by curiosity, but especially by reorienting towards a (more) healthier lifestyle, people seek to find out as much detail as possible about them - thus capturing the outline and the present work. Although eco-house construction is simple and eliminates many of the heavy stages of a classical construction, future homeowners omit, due to lack of information, this option, especially in the context in which we do not have a good filter of information about this subject, which will give us the real benefits we have. Ecologic houses seem to be a trend with strong growth, because the shapes that they can wear are extremely varied. The great variety, low price and promise of ecological housing is likely to convince people to completely change their lifestyle. How well are we prepared for sustainable development? How do we meet the demands of today's society? What does a green house look lik...
