Purpose/Thesis: The paper contains a methodological reflection on qualitative analysis of visual empirical data as a research procedure in the contemporary human information behavior research. The possibility of implementing this approach has been tested on a case study of personalized information spaces in everyday life of undergraduate information management students in the academic year 2018/2019.Approach/Methods: The reported research employs the realist epistemological stance, qualitative and descriptive approaches, and four methods/techniques: critical literature review, case study, drawing as a mental mapping tool, and thematic analysis. Results and conclusions: Visual data analysis is cognitively fruitful; it enables grasping the multidimensional “information reality” as perceived by the users (the humanistic coefficient). However, it is time-consuming, it requires meticulousness and self-reflection on the part of the researcher; it must also leave a clear audit trail to assure credibility and intersubjective verifiability of investigations.Originality/Value: The article is concerned with innovative research procedures, rarely discussed in Polish information science literature. Combining visual approach with individual information spaces, it corresponds to the latest methodological and topical trends in the field of information behavior. It also links theoretical reflection with the research practice.

Absorption chillers are one of the most used equipment in industrial, commercial, and domestic applications. For the places where high cooling is required, they are utilized in a network to perform the cooling demand. The main objective of the current study was to find the optimum operating conditions of a network of steam absorption chillers according to energy and economic viewpoints. Firstly, energy and economic analysis and modeling of the absorption chiller network were carried out to have a deep understanding of the network and investigate the effects of operating conditions. Finally, the particle swarm optimization search algorithm was employed to find an optimum levelized total costs of the plant. The absorption chiller network plant of the Marun Petrochemical Complex in Iran was selected as a case study. To verify the simulation results, the outputs of energy modeling were compared with the measured values. The comparison with experimental results indicated that the developed model could predict the working condition of the absorption chiller network with high accuracy. The economic analysis results revealed that the levelized total costs of the plant is 1730 $/kW and the payback period is three years. The optimization findings indicated that working at optimal conditions reduces the levelized total costs of the plant by 8.5%, compared to the design condition.

The purpose of this research was to determine strategies used by 8th grade students in Number Sense problems. This was a case study of 28 8th grade students at three similar secondary schools in a city centre south of Turkey. A Number Sense test consisting of 25 items designed according to five main Number Sense components was used as a data collection tool. The data were analyzed using qualitative analysis methods. The students preferred Strategies Based on Rules while solving the Number Sense test compared to strategies based on number sense or Strategies Partially Based on Number Sense.

Em 1986, foi criado nos Estados Unidos a Rails-to-Trails Conservancy, entidade sem fins lucrativos com a missão de contribuir para conservação do patrimônio ferroviário, transformando os ramais abandonados em trilhas ferroviárias destinadas, exclusivamente, para caminhantes, ciclistas e cavaleiros. Com essa perspectiva, há 15 anos iniciou-se uma mobilização comunitária para transformar o antigo Ramal Ferroviário Corinto-Diamantina, localizado no Vale do Jequitinhonha/MG, na primeira trilha ferroviária do Brasil, denominada Trilha Verde da Maria Fumaça - TVMF. Além da conservação dos bens ferroviários, a TVMF busca a dinamização da economia local através do Turismo de Base Comunitária. Este artigo corresponde a um estudo de caso da TVMF, de caráter exploratório-descritivo. A pesquisa envolveu revisão bibliográfica e entrevista do gestor da ONG Caminhos da Serra, utilizando questionário semiestruturado. A análise qualitativa dos dados permitiu obter resultados que proporcionam o entendimento sobre a TVMF, contribuem para a abertura da discussão sobre trilhas ferroviárias no Brasil e fornecem informações para subsidiar aplicações práticas em outras ferrovias que se encontram abandonadas. Trilha Verde da Maria Fumaça: railroad heritage and tourism in the Vale do Jequitinhonha (Brazil). In 1986, the Rails-to-Trails Conservancy was created in the United States, a nonprofit organization with a mission to contribute to conservation of the railway heritage, turning extensions abandoned on rails trails, designed exclusively for walkers, cyclists and riders. With this perspective, 15 years ago a community began a mobilization to transform the old Railway Corinto-Diamantina, located in Vale do Jequitinhonha / MG, into the first rail trails in Brazil, called Trilha Verde da Maria Fumaça - TVMF. In addition to the conservation of rail assets, TVMF seeks to stimulate the local economy through the Community Based Tourism. This article is an exploratory and descriptive case study of TVMF. The research involved literature review and interview questions for the manager of the NGO Caminhos da Serra, by using semi-structured questionnaire. Through qualitative analysis of data it was possible to get results that provide an understanding of the TVMF, contribute to opening the discussion about rails trails in Brazil, and provide information to support practical applications in other railways that are abandoned. KEYWORDS: Railway Tourism; Sustainable Tourism; Rails Trails.
