The water management of cities and villages faces many challenges. Aging infrastructure systems operate for many years after their theoretical lifetime (operation) with a very high need for reconstruction and repair. The solution is proper rainwater management. The investigated area is part of the cadastral area of the Nitra city. This article is based on the use of geographic information systems (GIS) as tools in proposing water retention measures that are needed to improve the microenvironment of the city. We proceeded in several steps, which consisted of area analysis, survey, surface runoff calculations in urbanized areas, proposal of a suitable solution for given location. For real possibilities of rainwater management procedures, a new site on the outskirts of the city was selected. In the given locality, it was possible to use water infiltration as a solution. The locality has suitable conditions of land ownership, pedological conditions, the slope of the area and also the interest of the inhabitants in the ecological solution. The outlined study indicates the need to continue research on the reliability of rainwater management practices.

The way in which an institution treats its records is crucial for its survival in a rapidly changing society. The purpose of the study was to investigate the records management practices and challenges faced by traditional institutions of leadership and governance in Ga Molepo, Limpopo, South Africa. The researcher employed a cross-sectional survey in order to quantitatively examine the challenges faced by members of traditional councils. A researcher administered questionnaire was used as a data collection tool to study a stratified sample of 35 members from an estimated population of 350. The findings revealed patterns and trends of non-compliance with records management standards and guidelines. Although there were sporadic cases of record keeping, a greater number of respondents revealed that traditional institutions lack the facilities, equipment, education and trained/skilled personnel to apply correct records management procedures in their daily administration of their traditional communities. The main value of the study is to create awareness of records management as one of the neglected areas in traditional institutions – which are by current legislative arrangement, the closest form of leadership and governance for rural communities in light of their relationship with local municipalities and the Department of Cooperative Governance and Traditional Affairs.

The City and County of San Francisco (“City”) embarked upon a 30-year master planning process in part prompted by public concerns related to the neighbourhood impacts of the Southeast Water Pollution Control Plant (SEP). The Sewer System Master Plan, as it is called, developed a long term Integrated Urban Watershed Management Plan for the City's treatment plants and collection system. This paper focuses on the planning framework and public input to the process, particularly as it relates to proposed changes to the SEP. The resulting improvements address issues of replacing aging infrastructure, eliminating odor emissions, and visually screening the treatment plants that are situated within an urban setting. The recommended project addresses the needed repair of the existing infrastructure; and proposes that the City move towards an integrated urban watershed approach, initially through localized rainwater harvesting and opportunistic water reclamation.

Activated sludges were acclimated to p-nitrophenol (PNP) in two operational modes, a batch and a continuous. The operational mode of the PNP acclimation of activated sludges strongly affected the physiological characteristics of predominant microorganisms responsible for PNP degradation. Predominant PNP degraders in the sludge in batch mode (Sludge B) had lower PNP affinity and were relatively insensitive to PNP concentration. Those of the sludge in continuous mode (Sludge C), on the other hand, had very high PNP affinity and were sensitive to PNP. MPN enumeration of PNP degraders in sludge B and C using media with different PNP concentrations (0.05, 0.2,0.5 and 2.0 mM) supported the above results. Medium with 0.2 mM of PNP did not recover PNP degraders in sludge C well, while it recovered PNP degraders in sludge B as well as the medium with 0.05 mM did. When switching from one operational mode to the other, the predominant population in sludge B shifted to the sensitive group, but that of sludge C did not shift at the given loading of PNP, showing relative resistance to inhibitive concentration.

The educational process, not only in our country, but also in the world, has undergone drastic changes since March 2020. The total transition from traditional classroom classes to distance education occurred due to the threat of the coronavirus pandemic (COVID-19). The changes affected not only the learning process, but also the innovative activities that were implemented in educational organizations. The purpose of this article is to describe and analyze the experience of spreading innovations in schools in the city of Krasnoyarsk during the pandemic to identify related problems and ways to solve them. The main idea of the work is to study the transformation of the phenomenon of educational innovations in school education in the context of universal distance learning. Within the framework of the study, the possibility of organizing distance learning and conducting innovative activities during the pandemic was monitored. The survey was conducted for all educational organizations in the city of Krasnoyarsk. Secondary analysis and interpretation of the survey results, systematization and classification of the theoretical and factual materials used, analysis of management practices and experience of educational organizations in the conditions of extreme transition to remote mode were carried out, which together made up the author’s research result. In the course of the work, the key problems faced by the education system of the city of Krasnoyarsk during the transition to remote operation were also identified.

OBJECTIVE: to characterize the profiles of families in the area covered by a Primary Health Center and to identify those in a vulnerable situation. METHOD: this is an epidemiological, observational, cross-sectional and quantitative study. 320 home visits were made, defined by a random sample of the areas covered by the Urban Center 1 in the city of São Sebastião, in Brazil's Federal District. A structured questionnaire was used for data collection, elaborated based on the Family Development Index (FDI). RESULTS: there was a predominance of young families, women, and low levels of schooling. The FDI permitted the identification of families in situations of "high" and "very high" vulnerability. The most critical dimensions were: "access to knowledge" and "access to work". CONCLUSION: the study indicated the importance of greater investments in the areas of education, work and income, and highlighted the need for the use of a wider concept of vulnerability by the health services.

Considerando a dinâmica e a estrutura urbana de Belém no início do século XXI como expressão da acumulação das intervenções urbanas e das práticas de planejamento e gestão do espaço da cidade, analisa-se a genealogia do planejamento urbano para compreender a produção de um espaço que tem como característica a negação da natureza e a produção da desigualdade entre classes sociais. Nesse aspecto, identificou-se três períodos específicos que produziram impactos significativos na produção do espaço urbano de Belém: o terceiro quarto do século XVIII (1755 – 1777) com as reformas promovidas no período Pombalino na Amazônia, momento de expressão de uma modernidade urbana e arquitetônica; o final do século XIX e a primeira década do século XX (1890 – 1910), momento de ascensão da economia regional a partir da intensificação de atividades extrativas que produziram reformas urbanísticas com tons higienistas e; por fim, o período entre 1940 e 1970, que marcou uma série de propostas de planejamento com viés técnico-burocrático na produção do espaço. Do ponto de vista da metodologia adotada, estabeleceu-se como percurso de pesquisa: i) levantamento bibliográfico de caráter teórico e empírico da temática; ii) levantamento documental acerca das práticas de planejamento e intervenção dos períodos destacados com base em legislação, planos e projetos de cada um dos períodos; iii) coleta de iconografia representativa da época as quais as políticas foram executadas. Apresenta-se como resultados a hipótese de que a narrativa de uma pretensa ausência de planejamento como fator explicativo dos problemas da cidade é um discurso que não tem base na realidade, posto que historicamente é exatamente o oposto que a pesquisa indica, as modalidades de planejamento efetivadas em Belém acentuam problemas como a segregação socioespacial.Palavras-Chave: História, Planejamento Urbano, Modernidade, Belém.AbstractConsidering the dynamics and urban structure of Belém at the beginning of the 21st Century as an expression of the accumulation of urban interventions and planning and management practices of the city, the historical genealogy of urban planning is analyzed as a way of understanding production of a space that has as characteristic the negation of the nature and the production of the inequality between social classes. In this aspect, three specific periods were identified that produced significant impacts on the production of the urban space of Belém: the third quarter of the seventeenth century (1755 - 1777) with the reforms promoted in the Pombaline period in the Amazon, a time of expression of an urban and architectural design; the end of the nineteenth century and the first decade of the twentieth century (1890 - 1910), a time of great rise of the regional economy from the intensification of extractive activities that produced urban reforms with hygienic tones; and finally, the period between 1940 and 1970, which marked a series of planning proposals with a bureaucratic technical aproach in the production of space in Belém. This work established as following research methodology: i) survey bibliographical of theoretical and empirical character of the analyzed subject; ii) documentary survey of the planning and intervention practices of the highlighted periods based on municipal, state and federal legislation, as well as the master plans and development plans of the periods; iii) collection of iconography representative of the time to which the policies were executed in the urban space. The hypothesis is that the narrative of a supposed absence of planning as a factor of the city's problems is a discourse that has no basis in reality, since historically it is exactly the opposite that the research indicates, that is, the modalities in Belém accentuate problems such as socio-spatial segregation.Keywords: History, Urban Planning, Modernity, Belém.

Liquefaction hazard zonation mapping of the Saitama City targeted on the Kanto Plain NW Edge Fault is described in this paper. The study involves the geotechnical properties of the alluvial soil of the city including Standard Penetration Test (SPT), shear wave velocity and other geological data analysis. The city being highly urbanized is situated on the soft soil (alluvial deposits) at the proximity of an active seismic fault that has increased the possibility of liquefaction hazard in the area. Kanto Plain NW Edge Fault is an active fault that lies very near to the Saitama City having the estimated possible earthquake magnitude of 7.4. The possible peak horizontal ground acceleration (amax) from this earthquake is calculated as from 0.15 g to 0.30 g. By considering all possible acceleration values the liquefaction potential maps were prepared and presented in this paper. Additionally, the shear wave velocity is very low and amplification ratio is very high at the marshy deposit but it has comparatively high velocity and low amplification ratio at the marine loam deposit area of the Omiya Plateau. In this paper the liquefaction potential of the area is expressed in terms of liquefaction potential index (PL). The PL value for the clayey silt deposit in the marshy area with shallow water table is very high. In addition, the PL value in the marine loam deposit of the Omiya Plateau is less which indicates that loam deposit has less liquefaction potential than marshy deposit. The map obtained from this study was validated with the field condition of the study area. Hence, it is expected that this study will assist in characterizing the seismic hazards and its mitigation and will provide valuable information for urban planning in the study area in future.

Abstract. The paper presents a novel adaptive parametric documentation, modelling and sharing methodology, which aims to achieve a continuous holistic documentation, data processing and sharing process for cultural heritage community, such as architects, engineers, archaeologists, conservators, programmers, fabricators, contest creators, game developers, scholars and common citizens. Thus, the use of advance parametric and building information modelling software allows the processing and specification of all data by creating the 3D models needed for the multidisciplinary experts. Two Cypriot case studies from the medieval time period have been chosen for the development, and evaluation of our proposed methodology in order to investigate the process of modelling and sharing all the given metadata and 3D data. The first one is the Asinou Church, a UNESCO Heritage stone monument in the Troodos Mountains with a unique interior and the Kolossi Castle, a former Crusader stronghold on the west of the city of Limassol on the island of Cyprus.
