Abstract. The difference between «landscape ecology» and «applied landscape ecology» is the path taken between research work and practical application. Therefore applied landscape ecology includes more than research and development. It works with scientific findings, modeis, methods, concepts etc. until they are ready for practical application.The corresponding Steps are basic research, calibration and Validation, model design, conceptualisation, decision making, development of models for practical application, pilot application and routine application. Four examples from the fields of landscape budget, conservation of natural resources, land use planning and landscape development present current concerns, methodical concepts, procedures, modeis and typical results of applied landscape ecological research. The various examples are classified methodically, their content is briefly commented and illustrated with maps. A look into the future summarises the basic elements of applied landscape ecological research: functions and processes, pro blems of probability and heterogeneity, knowledge based modelling at a high integration level and GIS as a working instrument.

Landscape Ecological

Competition for land is increasing as demand for multiple land uses and ecosystem services rises. Land regulation of the principles of landscape ecology is necessary to develop more sustainable approaches to land use planning. The research evaluated the present land patterns and determined best practices for its regulation of Dongwang Township in Quyang County, located in the Taihang Mountain area of Hebei Province, China. The research used the landscape ecology theory to construct an index system for landscape pattern analysis based on the GIS and Fragstats 3.3 software. In this study, we examined the specific reasons that landscape ecology is superior to traditional methods in land consolidation planning and design, which is conducive to the comprehensive development of land ecological benefits. Landscape ecological planning can effectively reduce landscape fragmentation and improve intensive management. The result found that the descending order of the Shannon index was current landscape, landscape ecological planning, and traditional planning. Landscape ecological planning could protect the natural diversity than traditional planning. Landscape ecological planning enables the creation of long corridors, with higher densities and connectivity and lower average corridor widths than traditional planning. Besides, it can improve ecological service function values in the study area to varying degrees, thus discouraging residents from limiting themselves to grain production. This research has great potential to improve the visibility of ecosystem services in local land use planning and, thus, to improve the ecological functioning of future landscapes.

Abstract The view of the development and cognition of landscape ecology should not be an isolated one. In order to comprehend the connection, complexity and cohesion of natural and social nature which influence the genesis, development and function of landscape ecology should be studied in time-spatial and landscape-ecological contextuality, complexity and integrity. This paper is devoted to the topic of time-spatial contextuality, complexity, and integrity of landscape ecology as a science approached from two points of view: firstly, the potential development of landscape ecology reflecting its object and approach of research and secondly, cognition of landscape ecology by landscape ecologists, i.e. subject of landscape ecological research. The mission of this paper is to at least partially enlighten so far less studied meta-scientific research field by means of selected theoretical and meta-scientific aspects.

AbstractAuthenticity and identity of landscape ecology is the core and synthesis of inherent conditions determining its development. Bringing into line the development of the theory, methodology and application it is possible to strengthen the social and scientific relevance of landscape ecology as the reflection of its theoretical-applied and educational maturity or development. Preservation of authenticity and determination of identity of landscape ecology depend first of all on the relationship between landscape-ecological research object (what is researched), landscape-ecological research approach (how it is researched) and landscape-ecological research subject (who researches). These three parts of landscape-ecological research are subject to a permanent development and change. The delineated meta-scientific, e.g. universal remarks seem to be applicable in an effort to ensure the preservation of the authenticity and identity as the condition of further development for the science solving the ecological-environmental and socio-economical problems in the landscape.

The Difference

Knowledge is created and learned by academicians for the purpose of further theory development. Academician’role in disseminating knowldege is very important. To reach a convergent understanding both theory and practice, it’s a need of flexibility between methodology and sources of data so that it stimulates actionable insight.One of the problems between theory and practice differencesis customers focus.For practicians customer focus raised three foundamentals questions: can the knowledge phylosophy reduce cost?. Can the knowledge phylosophy increse sales?, and can the knowledge phylosophy increase the profit?. This paper discuss the development of marketing knowledge based on the marketing practice to bridge the gap between academicians and practicians. Issues being discussed in this paper are the meaning of marketing knowledge from practician perspective, the theory of marketing in practician’s world, actionable research as the bridge of knowledge development, and the difference perspective between academician and parctician.

The Difference

Thermal and self-curing acrylic resins are frequently and versatilely used in dental medicine since they are biocompatible, have no flavor or odor, have satisfactory thermal qualities and polishing capacity, and are easy and fast. Thus, given their widespread use, their fracture resistance behavior is especially important. In this research work, we comparatively analyzed the fracture resistance capacity of thermo and self-curing acrylic resins in vitro. Materials and Methods: Five prosthesis bases were created for each of the following acrylic resins: Lucitone®, ProBase®, and Megacryl®, which were submitted to different forces through the use of the CS® Dental Testing Machine, usually mobilized in the context of fatigue tests. To this end, a point was defined in the center of the anterior edge of the aforementioned acrylic resin bases, for which the peak tended until a fracture occurred. Thermosetting resins were, on average, more resistant to fracture than self-curable resins, although the difference was not statistically significant. The thermosetting resins of the Lucitone® and Probase® brands demonstrated behavior that was more resistant to fracture than the self-curing homologues, although the difference was not statistically significant. Thermosetting resins tended to be, on average, more resistant to fracture and exhibited the maximum values for impact strength, compressive strength, tensile strength, hardness, and dimensional accuracy than self-curing resins, regardless of brand.

Purpose This paper aims to develop a knowledge-based (KB) system for Lean Six Sigma (LSS) maintenance in environmentally sustainable buildings (Lean6-SBM). Design/methodology/approach The Lean6-SBM conceptual framework has been developed using the rule base approach of KB system and joint integration with gauge absence prerequisites (GAP) technique. A comprehensive literature review is given for the main pillars of the framework with a typical output of GAP analysis. Findings Implementation of LSS in the sustainable building maintenance context requires a pre-assessment of the organisation’s capabilities. A conceptual framework with a design structure is proposed to tackle this issue with the provision of an enhancing strategic and operational decision-making hierarchy. Research limitations/implications Future research work might consider validating this framework in other type of industries. Practical implications Maintenance activities in environmentally sustainable buildings must take prodigious standards into consideration, and, therefore, a robust quality assurance measure has to be integrated. Originality/value The significance of this research is to present a novel use of hybrid KB/GAP methodologies to develop a Lean6-SBM system. The originality and novelty of this approach will assist in identifying quality perspectives while implementing different maintenance strategies in the sustainable building context.

1 The described analytical procedure permits the simultaneous determination of the main n-hexane meta bolites in urine. 2-Hexanone, 2-hexanol, 2, 5-hexanediol and 2, 5-hexanedione, were chosen to dose the rats used in this study. All urine samples were collected and analysed on a daily basis, before and after acidic hydrolysis (pH 0.1) by GC/MS. 2-Hexanone, 2, 5-dimethylfurane, γ-valerolac tone and 2, 5-hexanedione were determined before hydro lysis ; 2-hexanol and 2, 5-hexanediol, after hydrolysis; and 5-hydroxy-2-hexanone and 4, 5-dihydroxy-2-hexanone were calculated by the difference between γ-valerolactone and 2, 5-hexanedione with and without hydrolysis, respectively. 2 A metabolic scheme was proposed reflecting the biotransformations undergone by the four compounds assayed. We consider 2, 5-dimethylfurane as a 'true metabolite' because the quantities detected were always greater before hydrolysis. 3 It has been reported that human and rat n-hexane metabolism follow a similar pattern. Therefore, as a practical application and without increasing either sample or time requirements, the simultaneous quantifi cation of the different metabolites and their excretion profile could provide better information about the metabolic situation of exposed workers than the determi nation of 2, 5-hexanedione alone. According to our experimental results, 4, 5-dihydroxy-2-hexanone itself would be a good toxicity indicator.

Research Problems

Estimating the semantic similarity between text data is one of the challenging and open research problems in the field of Natural Language Processing (NLP). The versatility of natural language makes it difficult to define rule-based methods for determining semantic similarity measures. To address this issue, various semantic similarity methods have been proposed over the years. This survey article traces the evolution of such methods beginning from traditional NLP techniques such as kernel-based methods to the most recent research work on transformer-based models, categorizing them based on their underlying principles as knowledge-based, corpus-based, deep neural network–based methods, and hybrid methods. Discussing the strengths and weaknesses of each method, this survey provides a comprehensive view of existing systems in place for new researchers to experiment and develop innovative ideas to address the issue of semantic similarity.

The purpose of the research work is to analyze the advantages and disadvantages of the «flexible» field of accreditation of forensic laboratories and the field of accreditation that has a rigid range. The development of standardization in forensic science, including the expansion of the number of forensic laboratories that build their activities in accordance with the requirements of the international standard GOST ISO/IEC 17025-2019 «General requirements for the competence of testing and calibration laboratories», encourages us to pay attention to this issue again. In the course of the study, the following conclusions were formulated. Insufficient clarity in defining the «flexible» scope of accreditation and differences in the understanding of its boundaries by the accreditation body, the forensic laboratory and the customer can lead to abuse by individual laboratories and the development of unfair competition. This argument in favor of abandoning the «flexible» field of accreditation for forensic laboratories seems to be much more weighty than the listed advantages of its practical application.
