Full textAbstract:
Purpose – The purpose of this paper is to describe a new approach to a well-known problem for digital libraries, how to search across multiple unrelated libraries with a single query. Design/methodology/approach – The approach involves creating new Dewey Decimal Classification terms and numbers from existing Dublin Core records. In total, 263,550 records were harvested from three digital libraries. Weighted key terms were extracted from the title, description and subject fields of each record. Ranked DDC classes were automatically generated from these key terms by considering DDC hierarchies via a series of filtering and aggregation stages. A mean reciprocal ranking evaluation compared a sample of 49 generated classes against DDC classes created by a trained librarian for the same records. Findings – The best results combined weighted key terms from the title, description and subject fields. Performance declines with increased specificity of DDC level. The results compare favorably with similar studies. Research limitations/implications – The metadata harvest required manual intervention and the evaluation was resource intensive. Future research will look at evaluation methodologies that take account of issues of consistency and ecological validity. Practical implications – The method does not require training data and is easily scalable. The pipeline can be customized for individual use cases, for example, recall or precision enhancing. Social implications – The approach can provide centralized access to information from multiple domains currently provided by individual digital libraries. Originality/value – The approach addresses metadata normalization in the context of web resources. The automatic classification approach accounts for matches within hierarchies, aggregating lower level matches to broader parents and thus approximates the practices of a human cataloger.

Full textAbstract:
Scientific libraries use different approaches and tools for subject retrieval. Issues related to electronic subject retrieval are widely discussed in the library community. The purpose of this review is to analyse publications of recent years on the aspects and problems related to subject retrieval in electronic catalogue (EC). For its preparation, the author used publications (and references to them) taken from the national bibliographic database — the Russian Science Citation Index (RSCI); the time coverage is 2003—2019. Particular attention in the studies is focused on the need to combine different information retrieval languages (IRL), thesauruses, subject headings and keywords to ensure effective and multi-aspect search. Since the domestic libraries have accumulated a lot of experience in indexing and retrieval through hierarchical classifications (UDC and LBC), it is necessary to use this at the full extent in the electronic subject retrieval. The authors of the recent studies on subject retrieval consider being the most effective the functioning of classification systems as part of the complex of linguistic tools of electronic catalogue. In the electronic environment, it becomes possible to use classification indexes as a set of characters that maximally reflect the content of the document, what involves the use of all fragments of the index as independent retrieval elements. However, the lexical composition of the classification information retrieval languages needs to be modified for effective use in the electronic catalogue. The main directions here can be as follows: unification of the structure and vocabulary of classification schedules, optimization of the structure of classification systems (using facetization principles), as well as formalization of the use of grammar tools, (it is necessary to ensure the unambiguity of their interpretation in the electronic catalogue). The review presents and analyses the areas where the subject retrieval has been developed in the electronic environment for over the past 16 years. For example, there has been developed and is being implemented the superstructure over Universal Decimal Classification (Library for Natural Sciences of the Russian Academy of Sciences), which allows users of the library to remotely conduct full-fledged subject retrieval. The paper also presents the new developments by the Russian State Library on subject retrieval, in particular, the project “Presentation of classification metadata of electronic libraries using linked data technology”. The author concludes that it is necessary to form a common space of related open data of various libraries.

Introduction. The material discussed in this journal is to explain and describe in detail the use of the classification system at the Regional Library of Lampung Province, what system is used, how it is used.
Data Collection Methods. The method used in this journal research is interview research and documentation study. The author also uses qualitative methods and literature studies.
Data Analysis. Analysis of the data using data reduction, data presentation, and make conclusions about the Regional Library of Lampung Province.
Results and Discussion. The results of this study are that the Lampung Provincial Library Service uses 2 classification systems, namely a manual system and also a digital system with the E-DDC application. The librarian at the Lampung Provincial Library Service uses E-DDC edition 23, although using two classification systems, the librarian at the Lampung Provincial Library Service still uses a manual system more often because if you use a digital system with the E-DDC application the librarian sometimes has problems when use it, however, the use of the E-DDC application is still being used today.
Conclusion. The use of the classification system in the Regional Library of Lampung Province uses two classification systems, namely the manual system and the E-DDC (Electronic-Dewey Decimal Classification) application. The manual system is still often used by librarians of the Lampung Province Regional Library, even so the E-DDC application is still used but rarely because sometimes it gets obstacles when you want to use it.

Classification systems are published primarily in the book form, for various purposes and in different versions. They are identified by the number or year of publication. The authors propose another variant of maintaining classification systems, i.e. in the card format.The authors discuss the issues of presenting classification schedules of popular classification systems on the Internet with special focus on their applications. They explain why privately owned classification systems, like Dewey Decimal Classification (DDC) and Universal Decimal Classification (UDC), are not published on the Internet, while the systems supported by government organizations (e.g. national libraries) are traditionally published openly. The authors provide the example of the Library of Congress Classification (LCC), which is the United States’ National Classification System and which is published on open access. The project of the open presentation of the Library-Bibliographical Classification (LBC) in several versions supplemented with indices on the website of the Russian State Library (RSL) is described in more detail. The possibilities for their use are analyzed.

Primary Sjogren’s syndrome (pSS) is one of the most frequent among the connective tissue diseases. Histological examination of the minor salivary gland (MSG) is important diagnostic method. The currently established histological criteria for pSS do not have absolute sensitivity and specificity, which makes the search for additional morphological hallmark relevant.Aim – to study of the qualitative and quantitative composition of cellular populations inflammatory infiltrates in MSG pSS patient with the assessment of additional diagnostic criteria for disease based on the data obtained.Subjects and methods. The study included 55 patients with a diagnosis of pSS according to the criteria of ACR/ EULAR 2016. The control group consisted of 18 healthy volunteers. A MSG biopsy was performed all subjects for histological and immunohistochemical studies with a quantitative assessment of CD3+, CD4+, CD8+, CD20+, CD21+, CD68+, CD138+ cells. Statistical data analysis was performed using the Statistica 10.0 for Windows (StatSoft Inc., USA). For comparison of quantitative traits, the Mann – Whitney U-test was used. To determine the diagnostic threshold of the number of a ROC analysis was performed. An operating characteristic curve was plotted. The area under the curve (AUC), diagnostic specificity, diagnostic sensitivity, diagnostic accuracy, likelihood ratio of the positive and negative results of the test were calculated. The construction of classification models, including the number of different cell types, was carried out using linear discriminant analysis.Results and discussion. The number of CD3+, CD4+, CD8+, CD20+, CD138+ cells in 4 mm2 (area of section) was significantly higher in the pSS group. The largest AUC were observed for the quantitative evaluation of CD3+ cells – 0.88 [95% confidence interval (CI): 0.80–0.96] and CD8+ cells – 0.87 [95% CI: 0.79–0.95], which at the specified diagnostic thresholds corresponded to the sensitivity of 70.9% [95% CI: 57.86–81.23] and 65.45% [95% CI: 52.25–76.64], specificity of 94.4% [95% CI: 74.24–99.72] and 100% [95% CI: 82.41–100], respectively. The CD21+ follicular dendritic cells were detected only in MSG of pSS group. AUC for quantitative assessment of these cells was 0.65 [95% CI: 0.52–0.78], sensitivity 29.1% [95% CI: 18.77–42.14] and specificity 100% [95% CI: 82.41–100]. Using the method of discriminant analysis, we designed classification models that included various combinations of the studied markers. The highest AUC among all possible combinations was observed for the decimal logarithms of the number of CD3+ and CD68+ cells – 0.92 [95% CI: 0.85–0.98], which for a given diagnostic threshold corresponded sensitivity – 81.82% [95% CI: 69.67–89.81], specificity – 94.4% [95% CI: 74.24–99.72].

Full textAbstract:
This paper investigates the semantics of topical, associative see-also relationships in schedule and table entries of the Dewey Decimal Classification (DDC) system. Based on the see-also relationships in a random sample of 100 classes containing one or more of these relationships, a semi-structured inventory of sources of see-also relationships is generated, of which the most important are lexical similarity, complementarity, facet difference, and relational configuration difference. The premise that see-also relationships based on lexical similarity may be language-specific is briefly examined. The paper concludes with recommendations on the continued use of see-also relationships in the DDC.

Universal Decimal Classification (UDC) is a flexible classification scheme that allows the full expression of the subject of a book. However such flexibility requires decisions to be taken on how to apply and use the schedules. This article discusses the choices made by Tate Library in its implementation of the classification scheme and how the Library has developed UDC for its in-house use, in particular the expansion of the section for modern art.

Abstract
Objective – To determine the current use of Dewey Decimal Classification in academic libraries in the United States of America (U.S.).
Design – Cross-sectional survey using a systematic sampling method.
Setting – Online academic library catalogues in the U.S.
Subjects – 3,973 academic library catalogues.
Methods – The researchers identified 3,973 academic libraries affiliated with degree-granting post-secondary institutions in the U.S. The researchers searched each library’s online catalogue for 10 terms from a predetermined list. From the results of each search, the researchers selected at least five titles, noted the classification scheme used to classify each title, and coded the library as using Dewey Decimal Classification (DDC), Library of Congress Classification (LCC), both DDC and LCC, or other classification schemes.
Based on the results of their data collection, the researchers calculated totals. The totals of this current study’s data collection were compared to statistics on DDC usage from two previous reports, one published in 1975 and one in 1996. The researchers performed statistical analyses to determine if there were any discernible trends from the earliest reported statistics through to the current study.
Main Results – Collections classified using DDC were present in 717 libraries (18.9%). Adjusting for the increase in the number of academic libraries in the U.S. between 1975 and 2017, DDC usage in academic libraries has declined by 56% in that time frame. The number of libraries with only DDC in evidence is unreported.
Conclusion – The previous four decades have seen a significant decrease in the use of DDC in U.S. academic libraries in favour of LCC; however, the rate at which DDC has disappeared from academic libraries has slowed dramatically since the 1960s. There is no clear indication that DDC will disappear from academic libraries completely.

Full textAbstract:
Purpose – The purpose of this paper is to explore the potential of applying the Dewey Decimal Classification (DDC) as an established knowledge organization system (KOS) for enhancing social tagging, with the ultimate purpose of improving subject indexing and information retrieval. Design/methodology/approach – Over 11,000 Intute metadata records in politics were used. Totally, 28 politics students were each given four tasks, in which a total of 60 resources were tagged in two different configurations, one with uncontrolled social tags only and another with uncontrolled social tags as well as suggestions from a controlled vocabulary. The controlled vocabulary was DDC comprising also mappings from the Library of Congress Subject Headings. Findings – The results demonstrate the importance of controlled vocabulary suggestions for indexing and retrieval: to help produce ideas of which tags to use, to make it easier to find focus for the tagging, to ensure consistency and to increase the number of access points in retrieval. The value and usefulness of the suggestions proved to be dependent on the quality of the suggestions, both as to conceptual relevance to the user and as to appropriateness of the terminology. Originality/value – No research has investigated the enhancement of social tagging with suggestions from the DDC, an established KOS, in a user trial, comparing social tagging only and social tagging enhanced with the suggestions. This paper is a final reflection on all aspects of the study.

Full textAbstract:
Subject access to physical or electronic resource collections can be divided into two complementary areas: searching and browsing. Searching involves the use of subject headings, indexing terms from a controlled vocabulary, or natural language keywords. Browsing, whether along a shelf or through a subject tree on the Web, requires the application of some kind of taxonomy or classification scheme. This article looks at what class schemes art libraries are using to arrange their book collections in the UK today. Based on an informal survey via the ARLIS e-mail discussion list, it appears that the Dewey Decimal Classification is not only the most commonly used class scheme, but the one most art libraries choose when they reclassify their library.

Full textAbstract:
Background: Several studies in mathematics education show the use of the physical abacus in the activities of teachers in initial graduation, emphasising, in their manipulation, practices with addition or subtraction operations, or yet, which express a direct translation of the numeral to the physical abacus and, vice versa, without, however, explaining part of the complexity involved the social practice of quantifying physical quantities, which even makes possible the structuring of the numeral. Objective: To show that the use of the abacus by teachers in initial training may not ensure the realisation or mastery of the practice of quantifying physical quantities with discrete units. Design: In this sense, a study and research path (SRP) was carried out based on the training of early years teachers. Environment and participants: 25 students in initial training of a degree course at a public educational institution participated in an activity on decimal number system (DNS), but largely positional number system (PNS), proposed based on a problem in an unusual context (for them), they mobilised to face and answer questions. Data collection and analysis: We present an excerpt from the empirical research forwarded by Ferreira (2020) with teachers in initial training. Results: The data observed in the empirical confirms the hypothesis of the existence of a problem regarding the use of the abacus as a possible facilitator in the structuring of non-decimal numbers through the practice of quantifying physical quantities. Conclusions: The results found with the teachers revealed, in addition to the problem of teacher training on what to teach and how to teach numerals, that using the abacus made it difficult, if not hindered, the practice of quantifying physical quantities with discrete units. We also found changes in the quality of the teachers’ relationships with structuring decimal and non-decimal numbers.

In 1972 Amankwe published a survey of ‘Africa in the standard classification schemes’. In this he concentrated principally on the Decimal Classification, The Library of Congress Classification and The Bibliographic Classification. He paid particular attention to the problems of area designation, language, literature and anthropology and to such related matters as historical and racial subdivisions. Since that date much has been published on specific topics but no attempt has been made to survey the field in its entirety and it is the intention of the present article to collect together the strands, draw attention to important publications and look towards the future, particularly with reference to the need for standardization with the increasing use of automated systems throughout the World. The author or the editor of this journal would welcome any additional information and in particular any ‘in-house’ versions of parts of classification schemes, subject headings lists and authority files for names of persons, corporate bodies, etc., with a view to promoting greater interchange and participation in the development of standards for bibliographic work.

It is told about the achievements of Russia: works on the history of library CS, the directions of theoretical studies. For example, he CS history is well studied – from ancient times to the present day. Interesting CS were developed in the 18–19th century (for the largest and some university libraries). Schedules of the foreign CS – complete translation of the Colon Classification and the Dewey Decimal Classification into Russian was published. Published Russian UDC retranslation in 10 volumes. The country has CS, recognized by the international community as the National System of Russia (firstly published in the years 1961–1968 in the 30 books). Contemporary classification practice is distinguished by the presence of variants of schedules – full, medium and abridged, in book and machine-readable form. The experience of developing classification schedules for children's and school libraries is unique. The conclusion is made: Russia certainly has a high level of classification culture.

Full textAbstract:
As the premier example of big data in the bibliographic world, WorldCat has the potential to support knowledge discovery in many arenas. After giving evidence for a big data characterization of WorldCat, the paper explores this knowledge discovery potential from two perspectives related to the Dewey Decimal Classification (DDC) system: (1) how WorldCat data can inform development of the DDC (classification analytics) and (2) how DDC-classified content in WorldCat can shed light on the bibliographic world itself (collection analytics). In the realm of classification analytics, WorldCat data support decisions to modify the DDC by expanding or reducing the number of classes, adding topical coverage, or adding subject access points; data analysis can support recognition of (1) trending topics and (2) the faceted structure of subject domains. In the realm of collection analytics, the paper considers as possible applications the use of the DDC in the topical "fingerprinting" of categorized content in WorldCat or in performing a bibliographic gap analysis.

Full textAbstract:
The article deals with the means of thematic search by library classification in the electronic catalog of the German National Library. It has been found that it is important to submit a classification system in the form of an interactive hierarchical thematic tree of knowledge that enables the user to limit their search to a specific topic area. The classification of the library with the electronic catalog has been expanded, which is an important factor in ensuring the completeness and accuracy of the thematic search, as well as the convenience and speed of functioning of the automated library search engine. An analysis of the thematic search tools in the electronic catalog of the German National Library by classification schemes and a complex of navigation and search tools of the information library system is carried out. It is emphasized that a necessary element of modern interlibrary communication is also the mandatory introduction into the system of thematic search of a national library of an international classification system, such as the M. Dewey classification. It has been found that providing relevant search results based on M. Dewey's Decimal Classification is the basis for enabling users to effectively use the resources collected in the online catalog of the German National Library.

The current structure of 583 Magnoliopsida (Dicotyledons) and 584 Liliopsida (Monocotyledons) in the Dewey Decimal Classification (DDC) system reflects changes made when the life sciences were thoroughly revised in 1996. Since that time, considerable progress has been made in the phylogenetic classification of angiosperms (flowering plants). In particular, APG III, the 2009 version of the classification developed by the Angiosperm Phylogeny Group, is finding use as a tool to organize both botanical information and botanical collections. The Dewey Editorial Office has received a request to revise 583–584 in light of this taxonomy ―as appropriate‖; relevant revisions would be likely to include both structural and terminological changes. In deciding how to provide accommodation for APG III, the Dewey editorial team must address many issues: Is APG III now stable enough and accepted broadly enough to be adopted as the basis for a major revision of the DDC? Should revisions in 583–584 be coordinated with parallel revisions in other parts of the life sciences? What revision strategies can be considered in revising 583-584 to accommodate APG III? What are their various strengths and weaknesses? How have other major classification schemes (e.g., the UDC) accommodated APG III? Discussion of these issues is guided by the principles (―editorial rules‖) that govern development of the DDC.

The survey method was considered most appropriate for this study because, it measures users background, experience and what they know about knowledge and skills in professional development in enhancing their knowledge in day to day working environment and it is well suited to the research questions taken up for this study. A total of 218 questionnaires were administered personally and 183 dully- filled-in questionnaire for received with response rate of 83.94% and were considered for analysis. The study findings were that 66.67% knew Dewey Decimal Classification (DDC), the National Library of Medicine Classification (NLM) with 14.75%.The response “No Answer” with 15.3% connotes these libraries have not classified their collection. Only 3.28% knew Library of Congress Classification though it is not much used in Indian libraries probably the respondents’ knowledge of this would be from their study. The mean and standard deviation are computed and ranks were assigned to each of the Medical databases corresponding to the respective designations. This comparison found MedInd/IndMed ranking is much higher than MEDLINE. So the data has no uniformity and conformity with the content and therefore the ranking are not commensurate with the subject content and wider use of the databases worldwide.

Full textAbstract:
The sensor drift problem is objective and inevitable, and drift compensation has essential research significance. For long-term drift, we propose a data preprocessing method, which is different from conventional research methods, and a machine learning framework that supports online self-training and data analysis without additional sensor production costs. The data preprocessing method proposed can effectively solve the problems of sign error, decimal point error, and outliers in data samples. The framework, which we call inertial machine learning, takes advantage of the recent inertia of high classification accuracy to extend the reliability of sensors. We establish a reasonable memory and forgetting mechanism for the framework, and the choice of base classifier is not limited. In this paper, we use a support vector machine as the base classifier and use the gas sensor array drift dataset in the UCI machine learning repository for experiments. By analyzing the experimental results, the classification accuracy is greatly improved, the effective time of the sensor array is extended by 4–10 months, and the time of single response and model adjustment is less than 300 ms, which is well in line with the actual application scenarios. The research ideas and results in this paper have a certain reference value for the research in related fields.

Previous studies have demonstrated that children use oral calculation procedures not taught in school. The present study provided evidence for situational variables that strongly influence the tendency to use such procedures. It also provided a qualitative analysis of the oral mathematics used by Brazilian third graders. Concrete problem situations were powerful elicitors of oral computation procedures, whereas computation exercises tended to elicit school-learned computation algorithms. Oral computation procedures involved the use of two reliably identifiable routines, decomposition and repeated grouping, that revealed the children's solid understanding of the decimal system. In general, the children were far more successful in using oral mathematics than written mathematics. An understanding of children's oral procedures may be useful in developing more successful programs for elementary mathematics instruction.

Full textAbstract:
The relationship between scripture and Christian liturgy is one that was discussed and assumed in much of the liturgical and ecumenical literature in the twentieth century. The majority of that work focused on the use of the Bible within liturgical rites in general and not within the text of specific liturgical rites. This article is a constructive proposal of a comprehensive taxonomy to describe all the possible ways that a liturgical text can appropriate scripture as a source. Such attention to the ways biblical texts and exegesis are reflected in euchological texts not only has the potential to provide clarity on how the early Christians related to the Bible in general and within their liturgical rites. It may also provide an additional source for answering questions about the dating and provenance of particular rites by identifying the overlap with strains of patristic exegesis, for which we possess significant evidence.

Full textAbstract:
Remote sensing and GIS are often used to assess spatiotemporal variations for land use/land cover (LULC) monitoring and classification. While LULC monitoring and classification has been undertaken in Eswatini, little attention has been given to ascertaining covered thematic areas, methods of image classification, and approaches and techniques for improving classification accuracy. This paper summarises and synthesizes the progress made in the Kingdom of Eswatini regarding the application of remote sensing and GIS in LULC monitoring and classification. Eight thematic areas (water resources mapping; land degradation; forestry; wildfire detection; urban expansion; crop production; disease surveillance; general mapping) dominate evaluated LULC studies, employing three LULC classification methods (classic; manual; advanced). While some studies include strengths and weaknesses of LULC classification techniques applied, others do not. This review shows that only two advanced classifiers (random forest; object-based) were identified from the reviewed articles. In addition, reviewed studies applied only two approaches (use of multi temporal data; fine spatial resolution data) and three techniques (use of ancillary data; post-classification procedure; the use of multisource data) for improving classification accuracy. Furthermore, the review finds that limited LULC investigations have been covered in Eswatini with a specific focus on the Sustainable Development Goals (SDGs). As such, this review recommends 1) the inclusion of higher resolution imagery for mapping purposes, 2) the adaptation of strengths and weaknesses for any image classification technique employed in future publications, 3) the use of more varied approaches and techniques for improving classification accuracy and area estimates, 4) inclusion of standard errors or confidence intervals for error-adjusted area estimates as part of accuracy assessment reporting, 5) the application of advanced image classifiers, and 6) the application of Earth Observation (EO) Analysis Ready Data (ARD) in the production of information for the support of the SDGs.

Full textAbstract:
Stereotypes about men being better than women at mathematics appear to influence female students’ interest and performance in mathematics. Given the potential motivational benefits of digital learning games, it is possible that games could help to reduce math anxiety, increase self-efficacy, and lead to better learning outcomes for female students. We are exploring this possibility in our work with Decimal Point, a digital learning game that scaffolds practice with decimal operations for 5th and 6th grade students. In several studies with various versions of the game, involving over 800 students across multiple years, we have consistently uncovered a learning advantage for female students with the game. In our most recent investigation of this gender effect, we decided to experiment with a central feature of the game: its use of prompted self-explanation to support student learning. Prior research has suggested that female students might benefit more from self-explanation than male students. In the new study, involving 214 middle school students, we compared three versions of self-explanation in the game – menu-based, scaffolded, and focused – each presenting students with a different type of prompted self-explanation after they solved problems in the game. We found that the focused approach led to more learning across all students than the menu-based approach, a result reported in an earlier paper. In the additional results reported in this paper, we again uncovered the gender effect – female students learned more from the game than male students, regardless of the version of self-explanation – and also found a trend in which female students made fewer self-explanation errors, suggesting they may have been more deliberate and thoughtful in their self-explanations. This self-explanation finding is a possible key to further investigation into how and why we see the gender effect in Decimal Point.

This study is a systematic review of literature on the classification of sounds in three domains - Bioacoustics, Biomedical acoustics, and Ecoacoustics. Specifically, 68 conferences and journal articles published between 2010 and 2019 were reviewed. The findings indicated that Support Vector Machines, Convolutional Neural Networks, Artificial Neural Networks, and statistical models were predominantly used in sound classification across the three domains. Also, the majority of studies that investigated medical acoustics focused on respiratory sounds analysis. Thus, it is suggested that studies in Biomedical acoustics should pay attention to the classification of other internal body organs to enhance diagnosis of a variety of medical conditions. With regard to Ecoacoustics, studies on extreme events such as tornadoes and earthquakes for early detection and warning systems were lacking. The review also revealed that marine and animal sound classification was dominant in Bioacoustics studies.

Full textAbstract:
On-farm studies provide a realistic setting to examine the impact of interactions of management practices on weed communities within various farming systems. Clustering farm units into groups that use similar management practices enables the replication of farm management systems within on-farm studies. The goal of this study is to objectively classify farm units into management systems on the basis of quantitative variables describing aspects of cropping history and chemical input levels using multivariate techniques. Twenty-eight Saskatchewan farmers provided details of their management practices from 1990 to 1997 through a series of questionnaires. Twelve variables derived from the questionnaires were used to describe cropping history, pesticide, tillage and fertilizer use on each farm unit. These variables were used to cluster farm units using minimum variance classification and NMS ordination. Both techniques identified seven farm management systems. The greatest differences were observed between organic and non-organic systems. Farm management systems that used annual fallow and continuous annual cropping histories were most similar. The consistent results obtained by use of the two unrelated methodologies indicate the utility of this approach for the classification of farm management systems. Key words: Farm management system, classification, cropping history, chemical input level, on-farm

The land use is then classified, and the classification scheme was adopted from United States Geological Survey (USGS) Land Use/ Land Cover Classification System. Supervised classification method has been used since it was proved by other research to be more accurate compared to unsupervised classification. Accuracy assessment was conducted to calculate the accuracy of the land use map produced so that at the end, a good quality of land use map is produced. The findings of this study is that, there had been an insignificant land use changes between the year 1989 and 2006. The conclusion is, Lojing had been experiencing changes in term of land use due to the increased socioeconomic activities especially agriculture and logging at the highlands of Lojing.

Full textAbstract:
Background:
Experimental research on the effects of treatments with homeopathic preparations on plants was last reviewed in 1990.
Aims:
The objective was to compile a systematic literature review on plant bioassays in homeopathic basic research using predefined criteria.
Methods:
Literature search was carried out on publications that reported experiments with homeopathic preparations on whole plants, seeds, plant parts or cells from 1920 to 2010, in healthy, abiotically or biotically stressed conditions. Outcomes had to be measured by established state-of-the-art procedures and statistically evaluated. Using a Manuscript Information Score (MIS) those publications were identified that provided sufficient information for proper interpretation (MIS > 5). Further evaluation focused on the use of adequate controls to investigate specific effects of homeopathic preparations and on the use of systematic negative control experiments to ensure proper system performance.
Results:
A total of 157 publications with plants were identified [1–3]. The 157 publications described a total of 167 experimental studies. 84 studies included statistics and 48 had a MIS > 5 allowing proper interpretation. 29 studies were identified with adequate controls to identify specific effects of homeopathic preparations, reporting significant effects of decimal and centesimal homeopathic potencies, including dilution levels beyond Avogadro’s number. Studies that tested series of consecutive potency levels reported a non-linear and discontinuous relation between effect and potency level. There were many individual studies with diverse methods and very few replication trials. 10 studies reported use of systematic negative control experiments, yielding evidence for the stability of the experimental set-up.
Conclusions:
Plant models appear to be a useful approach to investigate basic research questions on homeopathic preparations, but more independent replication trials and systematic research are needed. Systematic negative control experiments should be implemented on a routine basis to exclude false-positive and false-negative results.

Objectives: The purpose of this study was to review the status of numeric rating scale (NRS) usage and suggest the potential for use in multicenter retrospective studies of various diseases.Methods: Articles published from 2011 to 2021 that used the keywords “NRS", “Multi-center", and “RCT" were identified in foreign databases, including EMBASE, PubMed, CENTRAL. The articles were analyzed according to their use of "NRS" by symptoms and by disease group using the major classifications of the Korean Standard Classification of Diseases (KCD-7).Results: Classification by symptom in a total of 288 articles illustrates that the NRS was not only commonly used in pain evaluation but also for non-pain symptoms. In usage with non-pain symptoms, chief complaint of patients was the most common at 79%, and other factors included treatment satisfaction, evaluation of daily life, and sleep quality. In disease classification according to the KCD-7, the NRS was commonly used in connection with musculoskeletal and connective tissue diseases but was also utilized in various other disease groups.Conclusions: This study confirms usage of the NRS in multi-center RCTs, as the NRS was widely used in all types of diseases and symptoms. Considering the result and the advantages of the NRS, it is recommended for use as a daily evaluation tool for the collection of common data in multicenter retrospective studies.

The use of regularization, random exclusion of rules from the rule base allows solving the problem of excessive similarity of rules in the rule base. The use of batch normalization to increase the generalizing properties of the network allows to increase the accuracy of the model, while maintaining the possibility of interpreting the results, which is characteristic of fuzzy neural networks. It is proposed to use an ensemble of fuzzy neural networks to increase the generalizing capabilities of the network. Studies of the Takagi-Sugeno-Kang fuzzy neural network for the task of diagnosing the coronavirus disease show that the proposed model works well and allows to improve the result.

SummaryTo develop a classification system to improve the reporting of observational studies of the use of information technology (IT) in clinical consultations.Literature review, workshops, and development of a position statement. We grouped the important aspects for consistent reporting into a “faceted classification”; the components relevant to a particular study to be used independently.The eightfacetsof ourclassification are: (1) Theoretical and methodological approach: e.g. dramaturgical, cognitive; (2) Data collection: Type and method of observation; (3) Room layout and environment: How this affects interaction between clinician, patient and computer. (4) Initiation and Interaction: Who starts the consultation, and how the participants interact; (5) Information and knowledge utilisation: What sources of information or decision support are used or provided; (6) Timing and type of consultation variables: Standard descriptors that can be used to allow comparison of duration and description of continuous activities (e.g. speech, eye contact) and episodic ones, such as prescribing; (7) Post-consultation impact measures: Satisfaction surveys and health economic assessment based on the perceived quality of the clinician-patient interaction; and (8) Data capture, storage, and export formats: How to archive and curate data to facilitate further analysis.Adoption of this classification should make it easier to interpret research findings and facilitate the synthesis of evidence across studies. Those engaged in IT-consultation research shouldconsider adopting this reporting guide.

This is the second and updated version of a paper with a similar name, that was published in this journal in [1], 1977. The basic idea of classification of the Fatigue Regime is implemented again, using updated fatigue studies, and the result is a new and updated diagram. Numerous studies on Fatigue Damage and Fatigue Crack Propagation dealt with these problems either by the cumulative damage approach, or by using crack propagation equations based on linear elastic fracture mechanics. Although these two approaches are not compatible, each is useful for predicting fatigue behavior with acceptable scatter, but only within defined limits. This study updates the “Fatigue Diagram,” which classifies different combinations of stresses and crack lengths in a given specimen, as zones in which different fatigue evaluation criteria govern. The whole fatigue regime is divided into six zones, that fit to known and to new prediction methods. For the more problematic zone, where the stress amplitude is higher than the fatigue limit, and the stress intensity factor range is higher than the threshold, a superposition of two prediction procedures is shown to match closely to test results in AISI 4XXX types of steel specimens. The fatigue diagram is shown to be a useful tool for dealing with real life, fatigue design problems. The “Threshold Crack Length” is reintroduced, and directions for additional studies are indicated.

Abstract. Land cover mapping using remote-sensing imagery has attracted significant attention in recent years. Classification of land use and land cover is an advantage of remote sensing technology which provides all information about land surface. Numerous studies have investigated land cover classification using different broad array of sensors, resolution, feature selection, classifiers, Classification Techniques and other features of interest from over the past decade. One, Pixel based image classification technique is widely used in the world which works on their per pixel spectral reflectance. Classification algorithms such as parallelepiped, minimum distance, maximum likelihood, Mahalanobis distance are some of the classification algorithms used in this technique. Other, Object based image classification is one of the most adapted land cover classification technique in recent time which also considers other parameters such as shape, colour, smoothness, compactness etc. apart from the spectral reflectance of single pixel.At present, there is a possibility of getting the more accurate information about the land cover classification by using latest technology, recent and relevant algorithms according to our study. In this study a combination of pixel-by-pixel image classification and object based image classification is done using different platforms like ArcGIS and e-cognition, respectively. The aim of the study is to analyze LULC pattern using satellite imagery and GIS for the Ahmedabad district in the state of Gujarat, India using a LISS-IV imagery acquired from January to April, 2017. The over-all accuracy of the classified map is 84.48% with Producer’s and User’s accuracy as 89.26% and 84.47% respectively. Kappa statistics for the classified map are calculated as 0.84. This classified map at 1:10,000 scale generated using recent available high resolution space borne data is a valuable input for various research studies over the study area and also provide useful information to town planners and civic authorities. The developed technique can be replicated for generating such LULC maps for other study areas as well.

Full textAbstract:
The recent development in satellite sensors provide images with very high spatial resolution that aids detailed mapping of Land Use Land Cover (LULC). But the heterogeneity in the landscapes often results in spectral variation within the same and spectral confusion among different LU/LC classes at finer spatial resolution. This leads to poor classification performances based on traditional spectral-based classification. Many studies have been addressed to improve this classification by incorporating texture information with multispectral images. Although different methods are available to extract textures from the satellite images, only a limited number of studies compared their performance in classification. The major problem with the existing texture measures is either scale/orientation/illumination variant (Haralick textures) or computationally difficult (Gabor textures) or less informative (Local binary pattern). This paper explores the use of texture information captured by Local Multiple Patterns (LMP) for LULC classification in a spectral-spatial classifier framework. LMP preserve more structural information and involves less computational efforts. Thus LMP is expected to be more promising for capturing spatial information from very high spatial resolution images. The proposed method is implemented with spectral bands and LMP derived from WorldView-2 multispectral imagery acquired for Madurai, India study area. The Multi-Layer-Perceptron neural network is used as a classifier. The proposed classification method is compared with LBP and conventional Maximum Likelihood Classification (MLC) separately. The classification results with 89.5% clarify the improvement offered by the LMP for LULC classification in comparison with the conventional approaches.
