- Principles of creative thinking - authors Prof. Ivanka Saykova, University of National and World Economy - Sofia, Prof. Svetlana Saykova, Institute for the Study of Societies and Knowledge at BAS - Sofia
The article discusses basic principles of creative thinking, which generate new ideas and useful changes in science and social practice. Usually, principles are seen as a guidance in one field or activity. In creative thinking they are something more. They are used as approaches and tools for mastering the technology, i.e. knowledge and skills to discover new ideas. Six such principles are discussed. The first four are produced by the English researcher E. de Bono, the other two are authors' invention. Together with the specific logic of creative thinking, they form the foundation of the technology of this thinking. They have been formulated relatively recently, and for many, they are still less known. And without their knowledge and understanding, it is difficult to master the methods and tools of this technology.
- Changing Concepts - A Method for Finding New Ideas and Opportunities for Making Changes in Social Practice and Scientific Knowledge - author Prof. Svetlana Saykova, Institute for Research on Societies and Knowledge at BAS
The article presents the author's vision of how change of concepts can stimulate creative thinking, generate new ideas and reveal alternative opportunities for solving issues, develop science and enhance the effectiveness of social practice. Ideas are discussed on the basis of a systematization of the ways (the paths) on which new ideas are born. The practical approach of the proposed approach is being discussed.

- Professor Anastas Y. Totev - biographical portrait - author Prof. Stoyan Totev, Institute for Economic Research, Bulgarian Academy of Sciences - Sofia
Prof. Anastas Y. Totev, born in Sofia in 1906, is one of the most versatile, colourful and impressive figures in the statistical community in Bulgaria. He has three degrees in higher education - Agronomy, Law, and Economics. His latest degree Economics and Statistics he received during his specialization and work in the 1930s at the research institutes of economic and social sciences at Cornell University. For some time he also specialized and worked at the renowned Harvard University. In the United States, he has a degree in economics at Cornell University.
Central place in Professor Totev's research work are theoretical and methodological issues of statistics. The broad specialization he acquired proves to be extremely useful for his research and lecturing activities. The gained knowledge explains the diverse interests and the multiple topics of the subjects he taught. They provide him the opportunity to work very successfully in his research and teaching activities in a number of major fields - Statistics, Economics, Prices and Finance, Demography, Sociology, Agronomy, Law and History.
Prof. Totev's life path is separated from the historical boundaries of different socio-economic conditions of the country as opposed to his creative path. In his public life, he is not a politician, but a scrupulous scientist. His entire research and lecturing activities bear the marks of uninvolved political civic activity and professionalism. His merits for science and university work are remembered by generations of statisticians. That is why attention deserve both the accumulated wealth from his works, as well as each of his publications and manifestations, which show the maturity, objectivity and conscientiousness of a great and humble Bulgarian scientist.
Prof. Anastas Totev died in 2000 in Sofia at the age of 93.

- Energy statistics from renewable sources and challenges - author Stoyanka Mastikova, National Statistical Institute - Sofia
In pursuit of the objectives of the transition to a low carbon, secure and competitive economy, at the end of 2018, the European Parliament has adopted new targets for the use of renewable energy and energy efficiency. By 2030, energy efficiency in the European Union (EU) should be improved to at least to 32.5%, while the share of energy from renewable sources (RES) should be at least 32% of the EU's final energy consumption.
Renewable energy sources are water energy, wind energy, solar photovoltaic energy, solar thermal energy, geothermal energy, biofuels, charcoal, biogas, landfill waste, liquid biofuels and the heat from the environment.
This article presents some major trends in the production and consumption of energy from renewable energy sources in Bulgaria in the context of meeting the goals set for the transition to a low carbon, secure and competitive economy. The focus of the article is information security and the challenges to energy statistics at the National Statistical Institute for providing the necessary data. Potential sources of information, such as administrative data, traditional statistical surveys, and intelligent measuring equipment (big data), have been reviewed. Special attention is paid to the progress made in the implementation of innovative approaches to data collection by Central Statistical Bureau of Netherlands.
- Census of cattle, poultry and bees in Bulgaria in 1905 and 1910 - author Zdravka Bobeva, National Statistical Institute - Sofia
The geographical location and terrain and climatic conditions determine Bulgaria's position among the countries with good agricultural development opportunities. The historical overview of the country's economy invariably places agriculture and livestock breeding among the leading sectors. Therefore, from the dawn of its existence, Bulgarian statistics has paid particular attention to the census of arable land, crop species, livestock breeding, both for the needs of the population and for their use as a workforce.
The censuses of 1905 and 1910 are the fourth and fifth consecutive years in the statistics on domestic animal breeding. This makes it possible to make comparisons with the initial data, to analyse the state of the sector, and to outline trends in the development of livestock breeding in Bulgaria.
The purpose of this information is to acquaint readers with the data on a segment of Bulgarian agriculture in the early 20th century.
- Population and housing census in Bulgaria in 1905 - author Sonya Zlatanova, National Statistical Institute - Sofia
On December 31, 1905, the fifth census of the population and the fourth census of the housing fund in the history of Bulgaria began.
According to the Law on the General Population Census, buildings and livestock in the Bulgarian Principality of December 15, 1897, the census should be carried out every five years. The first preparatory measure prior to the census is the numbering of buildings. It was necessary to have the buildings numbered in advance in each populated place, re-numbered where none existed, or to check, repair or supplement the existing one. All census data for the population, buildings and livestock are collected and entered only in the form (enumerating form) prepared by the Directorate of Statistics, which have been sent to the municipal authorities. At the same time, the data collected during the census serve to allocate the population by gender, age, nationality, mother tongue, nationality, religion, literacy, natural handicaps and by households. Special county and county census commissions are taking care for the proper conduct of the census, which distribute the municipalities into census districts and determine the required number of census agents. The census on 31 December 1905 was conducted in 1 893 municipalities of the Principality by 20 834 agent-enumerators, of which 5 924 were in the cities and 14 910 in the villages. An average of 194 inhabitants were enumerated by one agent-enumerator, of which 133 are urban enumerators and 218 are rural enumerators. The processing of the data collected during the census is carried out in the Directorate of Statistics.
Publications from the census of population and housing fund in 1905 have been digitized and are freely available at the NSI's digital library. The digital collection contains 2 884 pages of statistical information.
