Mountains have distinct geography and are dynamic in nature compared to the plains. 'Verticality' and 'variation' are two fundamental specificities of the mountain geography. They possess distinct temporal and spatial characteristics in a unique socio-cultural setting. There is an ever increasing need for spatial and temporal data for planning and management activities; and Geo Information (GI) Science (including Geographic Information and Earth Observation Systems). This is being recognized more and more as a common platform for integrating spatial data with social, economic and environmental data and information from different sources. This paper investigates the applicability and challenges of GISscience in the context of mountain geography with ample evidences and observations from the mountain specific publications, empirical research findings and reports. The contextual explanation of mountain geography, mountain specific problems, scientific concerns about the mountain geography, advances in GIScience, the role of GIScience for sustainable development, challenges on application of GIScience in the contexts of mountains are the points of discussion. Finally, conclusion has been made with some specific action oriented recommendations.

Pipelines are multidisciplinary projects from their planning, design, and construction to their maintenance and upgrade. The success of a pipeline project relies heavily on coordination among environmental assessment disciplines, clients, subcontractors, and vendors. Geographic information systems (GIS) play a major role in managing data and information across disciplines, and each environmental consulting company usually has at least one GIS department, which takes a lead role in maintaining current and historical data and information, and distributing it to various disciplines and business partners. We are developing a novel algorithm to utilize spatial data and convert it into useful geo-spatial information that a GIS department can directly utilize. Pipeline and environmental data from different sources undergo automatic registration, where common features between datasets are automatically detected and geometric transformation functions are automatically estimated. Experimental results demonstrate the robustness of the algorithm against changes or outliners and the accuracy of the transformation.

Spatial data, ranging from various land information data to different types of environmental data, are typically collected and used by different custodians. The full benefits of using spatial data can be achieved by combining the data from different sources covering a common region. Due to organizational, political and technical reasons, it is unrealistic to physically integrate the vast amount of spatial data managed by different systems in different organizations. A practical approach is to provide interoperability to support multi-site data queries. In this paper, we study the performance aspect of complex spatial query processing. We propose a framework for processing queries with multiple spatial and aspatial predicates using data from multiple sites. Using a new concept called generalized filter, a query is processed in three steps. First, an aspatial filter that incorporates some conditions derived from spatial predicates is used to find a set of candidates, which is a superset of the final query results. Then, the candidates are manipulated and a refinement step is executed following an optimized candidate sequence. Finally, a post-processing step is used to handle spatial expressions in query results. The focus of this paper is to generate enhanced filters in order to minimize the need of transferring and processing complex spatial data.

The results of our studies and the data of modern literature regarding the biological role of Cr(III) compounds in conditions of their application in the nutrition for pigs and cattle are discussed. The metabolic impact of Cr(III), coming from different sources – mineral and organic compounds, obtained by chemical synthesis or a nanotechnological method (chromium citrate), as well as in the form of biocomplexes from the cultural medium of Saccharomyces cerevisiae yeasts was analyzed. The metabolic connection between the impact of Cr(III) and the biosynthesis of some hormones – insulin, cortisol – as well as the sensitivity of some tissues and organs to the effect of chromium compounds was studied. A considerable part of the review material was dedicated to the metabolic effect of Cr(III) compounds on the reproductive function of pigs and cattle and their impact on the viability of the offspring and gametes of animals. The data about the stimulating effect of Cr(III) on the growth and development of the organism of piglets and calves, meat and milk performance of these species of animals are discussed. The relevance of dosing Cr(III) in the nutrition of pigs and cattle is highlighted.

Abstract. The purpose of this research is to analyze the role of Panglima Laot in the management of fishery resources in Sabang Island. To be able to understand the fisheries management that involves the role of the community in the form of local institutions, a series in-depth interview, observation, as well as literature were successfully carried out to local fishery community. Since this study is a combination of qualitative and quantitative method, the data collection was analysed using phenomenological approach and critical interpretation process to see the validity and reliability of the research findings.  Referring to previous research evidence, the results show that the presence of Panglima Laot has played an important role in providing information, invitation, supervision and participation in the management of fishery resources. In addition, the role of Panglima Laot in the management of fishery resources includes carrying out customs, assisting the government, resolving conflicts in the community, preventing illegal fishing, preserving the coastal environment and fighting for the living standards of fishermen is very influential both in centralization and decentralization era.  Therefore, these findings can be categorized as a useful information for any party working in field of fishery program.

Communal Space

Sharing practices are an important part of urban life. This article examines the appropriation of alleys as communal space to understand how sharing practices are embedded in localities, how communal space is constituted and maintained, and how this sustains communal life. In this way, the article aims to understand the spatial dimension of sharing practices, and the role of communal space in strengthening social relationship networks and urban sustainability. Seowon Maeul and Samdeok Maeul in Seoul are compared in terms of their urban regeneration approaches, community engagement in planning, street improvement, and the consequences that the transformation had on the appropriation of alleys as communal space. The research findings show that community engagement in planning is as important as the provision of public space if streets are to be appropriated as communal space. Community engagement has changed residents' perception and use of alleys as a shared resource in the neighbourhood by improving their capacity to act collectively and collaborate with other stakeholders in addressing problems and opportunities in cities.

CD38 is a transmembrane glycoprotein that is widely expressed in a variety of human tissues and cells, especially those in the immune system. CD38 protein was previously considered as a cell activation marker, and today monoclonal antibodies targeting CD38 have witnessed great achievements in multiple myeloma and promoted researchers to conduct research on other tumors. In this review, we provide a wide-ranging review of the biology and function of the human molecule outside the field of myeloma. We focus mainly on current research findings to summarize and update the findings gathered from diverse areas of study. Based on these findings, we attempt to extend the role of CD38 in the context of therapy of solid tumors and expand the role of the molecule from a simple marker to an immunomodulator.

Geoinformation technologies are now becoming “end-to-end” technologies of the new digital economy. There is a need for solutions for efficient processing of spatial and spatio-temporal data that could be applied in various sectors of this new economy. Such solutions are necessary, for example, for cyberphysical systems. Essential components of cyberphysical systems are high-performance and easy-scalable data acquisition systems based on smart geosensor networks. This article discusses the problem of choosing a software environment for this kind of systems, provides a review and a comparative analysis of various open source software environments designed for large spatial data and spatial-temporal data streams processing in computer clusters. It is shown that the software framework STARK can be used to process spatial-temporal data streams in spatial-temporal data streams. An extension of the STARK class system based on the type system for spatial-temporal data streams developed by one of the authors of this article is proposed. The models and data representations obtained as a result of the proposed expansion can be used not only for processing spatial-temporal data streams in data acquisition systems based on smart geosensor networks, but also for processing spatial-temporal data streams in various purposes geoinformation systems that use processing data in computer clusters.

This interdisciplinary volume presents nineteen chapters by Roman historians and archaeologists, discussing trade in the Roman Empire in the period c.100 BC to AD 350, and in particular the role of the Roman state, in shaping the institutional framework for trade within and outside the Empire, in taxing that trade, and in intervening in the markets to ensure the supply of particular commodities, especially for the city of Rome and for the army. The chapters in this volume address facets of the subject on the basis of widely different sources of evidence—historical, papyrological, and archaeological—and are grouped in three sections: institutional factors (taxation, legal structures, market regulation, financial institutions); evidence for long-distance trade within the Empire, in wood, stone, glass, and pottery; and trade beyond the frontiers, with the East (as far as China), India, Arabia, and the Red Sea, and the Sahara. Rome’s external trade with realms to the east emerges as being of particular significance to the fisc. But in the eastern part of the Empire at least, the state appears, in collaboration with the elite holders of wealth, to have adapted the mechanisms of taxation, both direct and indirect, to support its need for revenue. On the other hand, the price of that collaboration, which was in effect a fiscal partnership, in slightly different forms in East and West, in the longer term fundamentally changed the political character of the Empire.
