Digital Identifier Systems: Comparative Evaluation
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2015

description: Identifier is one of the main elements in identifying an object in digital environment. Digital identifier systems were developed followed by a lot of problems such as violation of persistency and uniqueness of physical identifiers and URL in digital environment. These identifiers try to guarantee uniqueness and persistency of hostnames by using indirect names for Domain Name System (DNS). The main objective of this research is to identify qualified digital identifier system among other systems. To achieve the research objective, researchers have considered two major steps: first, identifying main criteria for distinguishing digital identifier based on literature review and focus group interview and second, performing a comparative evaluation on common identifier systems in the world. Findings of first step demonstrated seven main criteria in three domains for distinguishing digital identifier systems: identifier uniqueness and persistency in the identifier features domain, digital identification, digital uniqueness, digital persistency and digital actionability in the digital coverage domain, and globality in the comprehensiveness of scope domain. In the second step, results of the comparative evaluation on common identifier systems indicated that six identifier systems, included, DOI, Handle, UCI, URN, ARK and PURL, are appropriate choices for using as a digital identifier system. Also, according to these results, three identification systems Including NBN, MARIAM and ISNI were identified as suitable choices for digital identification in certain specialized fields. According to many benefits of using these identifiers in important applied fields, such as, digital content chains and networks integration, digital right management, cross referencing, digital libraries and citation analysis, results of this study can help digital environment experts to diagnose digital identifier and their effective use in applied fields.

description: Cloud computing as a new technology with Internet infrastructure and new approaches can be significant benefits in providing medical services electronically. Aplying this technology in E-Health requires consideration of various factors. The main objective of this study is to identify and rank the factors influencing the adoption of e-health cloud. Based on the Technology-Organization-Environment (TOE) framework and Human-Organization-Technology fit (HOT-fit) model, 16 sub-factors were identified in four major factors. With survey of 60 experts, academics and experts in health information technology and with the help of fuzzy analytic hierarchy process had ranked these sub-factors and factors. In the literature, considering newness this study, no internal or external study, have not alluded these number of criteria. The results show that when deciding to adopt cloud computing in E-Health, respectively, must be considered technological, human, organizational and environmental factors.

description: The main objective of accelerated life tests (ALTs) is to predict fraction failings of products in the field. However, there are often discrepancies between the predicted fraction failing from the lab testing data and that from the field failure data, due to the yet unobserved heterogeneities in usage and operating conditions. Most previous research on ALT planning and data analysis ignores the discrepancies, resulting in inferior test plans and biased predictions. In this paper we model the heterogeneous environments together with their effects on the product failures as a frailty term to link the lab failure time distribution and field failure time distribution of a product. We show that in the presence of the heterogeneous operating conditions, the hazard rate function of the field failure time distribution exhibits a range of shapes. Statistical inference procedure for the frailty models is developed when both the ALT data and the field failure data are available. Based on the frailty models, optimal ALT plans aimed at predicting the field failure time distribution are obtained. The developed methods are demonstrated through a real life example.

Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2015

description: The purpose of this research lies in analyzing strategic plan dimensions for research development in the Organization of Libraries, Museums and Documentation Center of Astan Quds Razavi. For this purpose, current status of research in the organization for four strategic development dimensions (attitude, policy, management, staffing) from the organization's senior professionals views have been investigated.\n\nThe method of this research is based on descriptive survey. 34 AQ organization's senior professionals were selected as a sample. The tool for collecting the data was a questionnaire made by researchers.\n\nThe data showed that there is a relative satisfaction of the researchdevelopment programs (with regard to four dimensions: attitude, policy, management, staffing) in the AQ organization. The positive attitude of AQ organization's senior professionals is an opportunity for research development. The data also showed that one of the more important challenges for AQ research development is a weakness in policy making dimension. Although there have been management issues in AQ organization research development, experts’ relative satisfaction of the quantity and quality of research projects could be promising for the possibility of changes in the research structure. However, some problems and challenges are: lack of research funding and low research fees, poor research facilities and conditions, necessity of encouraging researchers to select and implement appropriate research projects, challenges about research findings advertisement, research administrative structure ineffectiveness, problems related to the publication of research findings and their implementation, failure to allocate adequate facilities for the research advancement and the lack of a suitable environment for development in research. The findings also showed that there is a good level of satisfaction about AQ organization interaction with other research organizations and researchers. There is dissatisfaction about low impact of research activities in staff gradation.

description: Limestone built heritage is at risk from the effects of biofilms, a microbial communityencapsulated in a matrix of sugars, protein and extracellular DNA. Although biofilm research hasbeen carried out in Mediterranean regions, few studies cover temperate Northern Europeclimates, or the UK. This study concentrates on bacterial colonisation of Lincoln limestone, ahighly vulnerable building material, and identifies the species, their role in biodeterioration andthe efficacy of biocides against them.As part of this study the core species which comprise the bacterial component of the limestonemicrobiome have been characterised for the first time; this has allowed the identification of noncore species which are significantly associated with damaged and undamaged surfaces.Four mechanisms of biodeterioration have been identified, one previously unidentified, andisolated species have been characterised as to whether they are biodeteriorative and themechanisms of biodeterioration that they employ. Two species, Curtobacterium flaccumfaciensand Solibacillus silvestris, have been characterised as producing biofilm matrix which activelycauses biomechanical damage to the oolitic limestone structure as opposed to the passiveenhancement of physical weathering which has been previously associated with biofilm matrix.Species capable of biodeterioration have also been shown to be present on both damaged andundamaged surfaces, something which has not been previously investigated.Environmental sampling, species identification and characterisation of species forbiodeterioration have all combined to identify markers of biodeterioration, ie both physicalmarkers and biomarkers. Specifically, a surface pH of 5.5 or lower and the presence of B.licheniformis is indicative of biodeterioration with a proportionally higher level of M. luteus whencomparing damaged and undamaged stone.Finally this study brings the literature on conservation methods up to date by testing biocideswhich are in current usage, as many biocides in the literature are discontinued. This study is alsothe first in the field to show their efficacy against biofilm encapsulated bacteria and theirpropensity for chemically disrupting the biofilm matrix.

description: As minimum feature size and pitch spacing further decrease, triple patterning lithography (TPL) is a possible 193nm extension along the paradigm of double patterning lithography (DPL). However, there is very little study on TPL layout decomposition. In this paper, we show that TPL layout decomposition is a more difficult problem than that for DPL. We then propose a general integer linear programming formulation for TPL layout decomposition which can simultaneously minimize conflict and stitch numbers. Since ILP has very poor scalability, we propose three acceleration techniques without sacrificing solution quality: independent component computation, layout graph simplification, and bridge computation. For very dense layouts, even with these speedup techniques, ILP formulation may still be too slow. Therefore, we propose a novel vector programming formulation for TPL decomposition, and solve it through effective semidefinite programming (SDP) approximation. Experimental results show that the ILP with acceleration techniques can reduce 82% runtime compared to the baseline ILP. Using SDP based algorithm, the runtime can be further reduced by 42% with some tradeoff in the stitch number (reduced by 7%) and the conflict (9% more). However, for very dense layouts, SDP based algorithm can achieve 140x speed-up even compared with accelerated ILP.

description: We have performed a comprehensive first-principles study of the electronic and magnetic properties of two-dimensional (2D) transition-metal dichalcogenide (TMD) heterobilayers MX2/MoS2 (M = Mo, Cr, W, Fe, V; X = S, Se). For M = Mo, Cr, W; X=S, Se, all heterobilayers show semiconducting characteristics with an indirect bandgap with the exception of the WSe2/MoS2 heterobilayer which retains the direct-band-gap character of the constituent monolayer. For M = Fe, V; X = S, Se, the MX2/MoS2 heterobilayers exhibit metallic characters. Particular attention of this study has been focused on engineering bandgap of the TMD heterobilayer materials via application of either a tensile strain or an external electric field. We find that with increasing either the biaxial or uniaxial tensile strain, the MX2/MoS2 (M=Mo, Cr, W; X=S, Se) heterobilayers can undergo a semiconductor-to-metal transition. For the WSe2/MoS2 heterobilayer, a direct-to-indirect bandgap transition may occur beyond a critical biaxial or uniaxial strain. For M (=Fe, V) and X (=S, Se), the magnetic moments of both metal and chalcogen atoms are enhanced when the MX2/MoS2 heterobilayers are under a biaxial tensile strain. Moreover, the bandgap of MX2/MoS2 (M=Mo, Cr, W; X=S, Se) heterobilayers can be reduced by the electric field. For two heterobilayers MSe2/MoS2 (M=Mo, Cr), PBE calculations suggest that the indirect-to-direct bandgap transition may occur under an external electric field. The transition is attributed to the enhanced spontaneous polarization. The tunable bandgaps in general and possible indirect-direct bandgap transitions due to tensile strain or external electric field endow the TMD heterobilayer materials a viable candidate for optoelectronic applications.

description: The thermal evolution of a few thermodynamic properties of the nuclear surface like its thermodynamic potential energy, entropy and the symmetry free energy are examined for both semi-infinite nuclear matter and finite nuclei. The Thomas-Fermi model is employed. Three Skyrme interactions, namely, SkM$^*$, SLy4 and SK255 are used for the calculations to gauge the dependence of the nuclear surface properties on the energy density functionals. For finite nuclei, the surface observables are computed from a global liquid-drop inspired fit of the energies and free energies of a host of nuclei covering the entire periodic table. The hot nuclear system is modelled in a subtracted Thomas-Fermi framework. Compared to semi-infinite nuclear matter, substantial changes in the surface symmetry energy of finite nuclei are indicated; surface thermodynamic potential energies for the two systems are, however, not too different. Analytic expressions to fit the temperature and asymmetry dependence of the surface thermodynamic potential of semi-infinite nuclear matter and the temperature dependence of the surface free energy of finite nuclei are given.

description: La réussite scolaire des élèves dépend de plusieurs facteurs de nature différente : la recherche dans les sciences de l’éducation a aujourd’hui bien documenté l’influence du statut socio-économique, du genre et d’origine culturelle de l’élève. Cela produit des inégalités sociales que l’école et ses acteurs devraient mitiger. Dans ce mémoire j’ai voulu comparer les résultats de la recherche aux représentations de six enseignants de mathématiques et de sciences d’un établissement vaudois du degré secondaire I. Pour ce faire, j’ai mené des entretiens semi-dirigés et je les ai analysés de manière qualitative descriptive. Les enseignants sont conscients de l’importance des facteurs familiaux pouvant influencer fortement la réussite des élèves. Selon leur perception, la division en filières (VG et VP) caractérisant le contexte vaudois renforcerait les inégalités. Les enseignants accordent moins d’importance à d’autres facteurs tel le genre et l’origine culturelle : dans ce cas, les impressions des enseignants sont atténuées en comparaison avec les résultats de la recherche. Il semble que les enseignants craignent que l’individuation des différences induise automatiquement une catégorisation nuisible aux apprentissages. Cependant, cette invisibilisation des différences fait surgir des interrogations quant aux possibles conséquences sur les élèves. Les enseignants ne perçoivent généralement pas de différence de réussite selon le genre, bien qu’ils soient conscients d’autres différences quant à la manière de se rapporter à l’école et au travail scolaire. Deux enseignantes femmes ont mis en avant leur rôle de modèle pour les filles dans les branches technoscientifiques. Les pratiques enseignantes décrites dans les entretiens sont très variées et adaptées en fonction de l’élève et de la classe. Cependant, dans le discours des enseignants, les pratiques ne semblent pas être explicitement dirigées vers une réduction des inégalités qui sont l’objet de ce mémoire. Cela pourrait découler en partie de l’invisibilisation de certaines différences.

description: A new set of DNA base-nucleic acid codes and their hypercomplex number representation have been introduced for taking the probability of each nucleotide into full account. A new scoring system has been proposed to suit the hypercomplex number representation of the DNA base-nucleic acid codes and incorporated with the method of dot matrix analysis and various algorithms of sequence alignment. The problem of DNA sequence alignment can be processed in a rather similar way as pairwise alignment of protein sequence.

description: Low power design has become one of the most significant requirements when CMOS technology entered the nanometer era. Therefore, timing budget is often performed to slow down as many components as possible so that timing slacks can be applied to reduce the power consumption while maintaining the performance of the whole design. Retiming is a procedure that involves the relocation of flip-flops (FFs) across logic gates to achieve faster clocking speed. In this paper we show that the retiming and slack budgeting problem can be formulated to a convex cost dual network flow problem. Both the theoretical analysis and experimental results show the efficiency of our approach which can not only reduce power consumption by 8.9%, but also speedup previous work by 500 times.

Year: 2014

description: Web presence is one of the areas of research in the field of webometrics. Due to lack of precise information on the presence of the Knowledge and Information Science (KIS) faculty members in Iran, this study aims to address this problem. It studies the level and quality of the presence of the LIS faculty and its relation to their professional effectiveness, focusing on their academic and professional performance. This study is an applied research, taking two approaches: descriptive survey and webometrics. The study participants are the KIS faculty members in Iran who hold a PhD degree, have senior lecturer (assistant professor) position and positions above that, and have scientific publications and web citations. A checklist was used to collect the webrelated data on their presence, and a questionnaire was designed to collect the data on their academic and professional activities. Three databases were used to collect the web-related data, namely Google, Google Scholar and the Iran Science Citation Index. The data was analyzed using statistical analysis and tests of descriptive and interpretive types. From the web presence perspective, the findings revealed that besides experienced academics, younger academic members have remarkable web presence. The findings showed that there is a meaningful relationship between the level of presence of the studyparticipants and their publications. KIS academics of Ferdowsi University of Mshhad and Shahid Chamran University of Ahvaz have gained highest positions according to publication web presence in Google. Also, scientific databases, self citations and university websites have got the first to third ranks in order to publication web presence themes. In addition, results showed us publishing Farsi and English articles in credible refereed journals is the most important theme in scientific and professional performance.

description: Nonlocal properties (globalness) of a non-separable unitary determine how the unitary affects the entanglement properties of a quantum state. We apply a given two-qubit unitary on a quadpartite system including two reference systems and analyze its "LOCC partial invertibility" under two-party LOCC. A decomposition given by Kraus and Cirac for two-qubit unitaries shows that the globalness is completely characterized by three parameters. Our analysis shows that the number of non-zero parameters (the Kraus-Cirac number) has an operational significance when converting entanglement properties of multipartite states. All two-qubit unitaries have the Kraus-Cirac number at most 3, while those with at most 1 or 2 are equivalent, up to local unitaries, to a controlled-unitary or matchgate, respectively. The presented operational framework distinguishes the untaries with the Kraus-Cirac number 2 and 3, which was not possible by the known measure of the operator Schmidt decomposition. We also analyze how the Kraus-Cirac number changes when two or more two-qubit unitaries are applied sequentially.

description: Rapid development of information technology, make a profound revolution in giving services to users. Suitable data for the suitable data seeker in a suitable time is a basic slogan used by librarians and activists in information services to use it in order to make the slogan more objective. Electronic reference services, such as Email, Chat, Cell phones and etc. are the most suitable devices to answer the needs of library users. The aim of this study was to identify ability of librarians and identify infrastructures required to provide electronic reference services in Ferdowsi University of Mashhad. In this regard, we measured the gap between the skills and the existing infrastructures as well as proper infrastructures and skills desired. Since similar experiences were not found in the previous researches instruments like questionnaire and interview checklist provided based on IFLA and RUSA guidelines and other related literatures. The study population were all librarians working in the Reference Services, information and Public services in Libraries of Ferdowsi University of Mashhad (32 person). Interviews were conducted with one of the administrative staff at the Central Library. The checklist was completed with the help of the head of each library. The findings showed that about 35% of reference librarians using less electronic reference services. in this field, Others evaluate themselves as moderate. And all the librarians (100 percent) were mentioned that offer of electronic reference services is necessary. Meanwhile, only 28% believed that librarians have the Technology skills and nearly 50% believe that they have the searching skills. In this regard, more than 60% of librarians said they have suitable skills. Based on the finding and the gap between present and ideal situation it seems that the usage rate of technology in its ideal form has the deepest gap and with the librarian's individual skills has not it.

description: Electronic information resources (EIR) play an important role in the process of education and research. The aim of this study was to analyze the status of adoption of electronic information resources (EIR) by Iranian Knowledge and Information Science (KIS) faculty members. This applied- descriptive survey was carried out on Iranian KIS Faculty Members in 2012. The number of participants was determined based on the Cochran's sample size table. Of the 170 Faculty Members, 122 individuals were randomly selected. Data collection tool was an Electronic questionnaire, and its validity was confirmed by professionals. The reliability of the questionnaire was verified after a pilot study. By using IBM SPSS 20 software and through exploratory factor analysis, descriptive statistics, and inferential tests the data were analyzed. Results showed that, there is significant difference between the mean of adoption rate of electronic information resources (EIR) by people with different levels of education. In addition, the Pearson correlation coefficient showed a significant relationship between mean of adoption rate and the faculty’s teaching experience and age. The results of Kolmogorov-Smirnoff test showed that the curve of adoption rate of electronic information resources among the sample is normal, and thus, the adoption rate of resources over time, is S-shaped. Ultimately, this study confirmed The Rogers’ Diffusion of Innovation Theory (2003) in context of Adaptor categories of electronic information resources (EIR), and S-shaped curve, among faculty members in departments of knowledge and Information science in Iran.

description: The recently released BICEP2 data detected the primordial B-mode polarization in the Cosmic Microwave Background (CMB) map which strongly supports for a large tensor-to-scalar ratio, and thus, is found to be in tension with the Planck experiment with no evidence of primordial gravitational waves. Such an observational tension, if confirmed by forthcoming measurements, would bring a theoretical challenge for the very early universe models. To address this issue, we in the present paper revisit a single field inflation model, which includes a modulated potential. We show that this inflation model can give rise to a sizable negative running behavior for the spectral index of primordial curvature perturbation and a large tensor-to-scalar ratio. Applying these properties, our model can nicely explain the combined Planck and BICEP2 observations. To examine the validity of analytic calculations, we numerically confront the predicted temperature and B-mode power spectra with the latest CMB observations and explicitly show that our model is consistent with the current data.

A Review on Information Seeking Behaviour Literature in Iran
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: This article reviews the condition of information seeking behavior in Iran with analytical and qualittatire approaches to exhibit a clear, scientific, and read condition of it. Published literature has been reviewed both in theoretical bases and accomplished researches. So, all published literature including books, articles, theses, and research plans that has been released and distributed in Iran and were effective in this domain, has been studied. Reviews showed that the information seeking behavior has had a developing trend in quality and quantity form the last seventeen years of its emerging in Iran. Lower than 4% of published literature has been translated. Most resources have studied the information seeking behavior in research form. Scholar’s information seeking behavior has been done in most researches (about 34% of all researches). Then students’ information seeking behavior (about 17%) and researches’ information seeking behavior (about 14%) has been done. The least attention has been about examination of publics’ information seeking behavior and public library members.

Evaluation Criteria of Information Retrieval Systems: What We Know and What We Do Not Know
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: Evaluation of information retrieval systems is one of the greatest challenges for information science specialists, because determining the performance of a system depends on judgment of the relevance of documents provided by the system to the user's information needs, and it has its own complexities. New retrieval systems due to the dynamic nature of the Web are very different compared with traditional retrieval systems. Web information retrieval systems in terms of ranking results are divided into two groups: The ranked retrieval results and unranked retrieval sets. Each system has a different evaluation criteria and scales. In this paper, criteria for evaluating information retrieval systems is reviewed for the ranked retrieval results (including precision and recall curves, interpolated precision, the 11-point interpolated precision average, Mean Average Precision, precision at K, R-precision, ROC curve cumulative gain and normalized discounted cumulative gain), and the unranked retrieval sets (including precision, recall, F-measure and accuracy) is introduced separately. Finally, alluding to the evaluation metrics, a scale of 4 degrees including best, useful, objective precision and then differential precision is introduced which can be used to evaluate the non-binary precision of web information retrieval systems.
Blind links, a big challenge in the linked data idea: Analysis of Persian Subject Headings
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: In this survey, Linked data concept as exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web and some potential problems in converting Persian subject headings (PSHs) Records into linked data were discussed. A data set (11233 records) of PSHs was searched in three information retrieval systems including National Library of Iran (NLI) online catalog, Library of Congress (LC) online catalog and NOSA books. Correct links between Persian and English subject headings in the 9519 common records of two catalogs were recorded. The results indicate that the links between Persian and English subjects in 20% of records were failed. The maximum error was associated with the anonymous databases (6/7 %) in NLI online catalog. It is recommended to preprocess the PSHs records before any conversion projects. It seems that, during the preprocessing, the potential errors could be identified and corrected.

description: Orthogonal frequency-division multiplexing (OFDM) in visible light communications (VLC) inherits the disadvantage of high peak-to-average power ratio (PAPR) from OFDM in radio frequency (RF) communications. The upper peak power and lower peak power of real-valued VLC-OFDM signals are both limited by the dynamic constraints of light emitting diodes (LEDs). The efficiency and transmitted electrical power are directly related with the upper PAPR (UPAPR) and lower PAPR (LPAPR) of VLC-OFDM. In this paper, we will derive the complementary cumulative distribution function (CCDF) of UPAPR and LPAPR, and investigate the joint distribution of UPAPR and LPAPR.

'How I Left The National Grid'; A Creative Writing PhD on Self-Design and Post Punk
Creators: name: Mankowski, Guy
Publisher: name: University of Lincoln
Year: 2023
Subjects: W830 - Prose writing

description: This PhD investigates, through creative and critical practice, how we might apply theories of self-design to understandings and creative representations of the post-punk movement. These theories inform the creative component of this PhD, a novel entitled How I Left The National Grid (hereafter, HILTNG). Through critical and creative practice this thesis will address three questions:1. What is self-design and how can we historicise it?2. Why is self-design evident in certain subcultures or cultural moments, particularly post-punk?3. What can a novel about self-design in post-punk do to address these questions and tell us about identity?To answer these questions, this PhD will consider how to represent people responding artistically to their environment, with a focus upon post-punk urban settings in 1980’s Britain. Through creative practice these people will be represented by attempting to recreate that environment in a cultural moment, which, as will become clear, is in many ways linked to the present day.These research questions inform the material aggregated here; in turn, this material seeks to address these questions by considering the perspectives, contexts and positions necessary for answering them. Before proceeding to outline the theoretical framework, I will define ‘post-punk’. It is necessary to do this, because this term has been used both to describe music and a repeated cultural moment. The use of this term in popular culture will be explored. This will be followed by a brief exploration of how post-punk music can be distinguished from new wave and industrial music, in order for us to establish key terms. This cultural moment will then be explored as an extension of the punk movement, within the context of post-modernism. This will allow the practices of punk and post-punk to be later understood within a sound theoretical context. The methods and tendencies of post-punk artists will then be investigated, to offer a practical dimension to this theoretical analysis. Considering the cultural and political context of post-punk is necessary in order to establish how a fictional post-punk band could be created in novel form. By so doing, the theoretical materials gathered here can be activated as creative practice. The first question will be directly addressed by then looking exactly at what self-design is. The second question will be explored by examining how self-design has evolved, up to and including the post-punk moment. The third question will then be addressed, by initially investigating how these understandings have been reflected in the novel form. Finally, the focus will turn to the ways in which HILTNG specifically reflected these concerns.
Objective and Subjective Relevance in Information Systems an Analysis of Relevance in Information Retrieval
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: Objective: The scope of debates between philosophers on objectivism and subjectivism relates to relevance which is fundamental issue of designing and evaluation of information systems. Our understanding of the topic relevance would not be complete without understanding these basic debates. The article reviewing both viewpoints tries to sum up them somehow acceptable and useful to information systems and with critical approach analyses subjective paradigm dominant in relevance literature. Methodology: The present study is based on the descriptive- analysis methodology using the library sources. Findings: Necessity of more moderate and realistic viewpoints which recognize the role of experts and systems in addition to users in the literature of relevance. Also introducing the “Facet Relevance”, it has been proposed objectivism and subjectivism be recognized not only to design information systems but also to defining relevance. The effects of technology on the approaches of information system design free from theoretical viewpoints investigated too.
Comparison of IranMARC Manual (for monographs), MARC21 & UNIMARC with 17 identified problems related to IranMARC
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2014

description: Due to UNIMARC is the basis for the IranMARC format, in this paper all 17 problems identified by Kokabi in 1994 about adoption of UNIMARC in Iran, were compared with IranMARC Manual to find the suggested solutions for them. Because of the international role of MARC21 and UNIMARC, these 17 problems were checked out to reveal if these problems are solved in last update of UNIMARC and if there is any solution for them in MARC21. Eventually with these findings, researchers determined that MARC21 has more adaption with special feature of Persian cataloging and bibliographic features.
