"hFlt3 Expression Marks Long-Term Hematopoietic Stem Cells, but Not the Pathway Common to Granulocyte/Monocyte and Lymphoid Lineages in Human Hematopoiesis." Blood 108, no. 11 (November 16, 2006): 1654. http://dx.doi.org/10.1182/blood.v108.11.1654.1654.
Full textAbstract:
Abstract Flt3 is a tyrosine kinase receptor, whose signals support proliferation and differentiation of early hematopoietic progenitors in cooperation with other cytokine signals. The concept of myeloid vs. lymphoid commitment in murine hematopoiesis has been challenged based on the analysis of Flt3 expression (Adolfsson et al, Cell, 2006): Long-term murine hematopoietic stem cells (HSCs) with self-renewal activity do not express murine Flt3 (mFlt3), but mFlt3 is upregulated in a fraction of progenitors common to granulocyte/monocyte and lymphoid lineages, suggesting the existence of the 3rd pathway of murine hematolymphoid development. In order to test whether Flt3 expression can delineate such a developmental pathway also in human hematopoiesis, we have analyzed the expression of human Flt3 (hFlt3) in prospectively-purified human stem and progenitors (PNAS 99, 2002) by utilizing 7-color FACS and a highly efficient xenograft systems. Surprisingly, all single human hCD34+hCD38-Thy-1+Lin-long-term HSCs expressed Flt3 at a low level. Purified Flt3lo HSCs can reconstitute NOD-scid/IL2Rγnull newborns (Blood 106, 2005) for a long-term after adoptive transfer of only 100 cells, and generated all hematopoietic cells including GM, megakaryocyte/erythrocyte (MegE), T, B and NK cells, providing formal proof that hFlt3 is expressed in long-term multipotent human HSCs. In the myeloid pathway, hCD34+hCD38+hCD45RA-IL-3RαloLin-CMPs expressed low to negative levels of hFlt3, and hCD34+hCD38+CD45RA-IL-3Rα-Lin-MEPs did not express Flt3. However, in marked contrast to murine progenitors, hCD34+hCD38+hCD45RA+IL-3RαloLin-GMPs uniformly expressed hFlt3 at the highest level. We then separated CMPs into 2 fractions with negative and low level expression of Flt3. In vitro culture in the presence of cytokine cocktail revealed that hFlt3lo CMPs differentiated into hFlt3-CMPs, hFlt3-MEPs and hFlt3hi GMPs, while hFlt3-CMPs mainly generated hFlt3-MEPs in vitro, suggesting that hFlt3lo CMPs is located upstream of the hFlt3-CMP stage that has skewed differentiation potential into the MegE lineage. In vitro differentiation activity of these progenitors was not affected with or without hFlt3 ligand in the culture. hFlt3 ligand, however, appeared to be able to maintain survival of hFlt3-expressing stem and progenitor cells at least in vitro. Thus, in striking contrast to mice, hFlt3 expression is already initiated at the most primitive long-term HSC stage, and is progressively upregulated in accordance with GM lineage differentiation. These data collectively suggest that the role of Flt3 signaling in hematopoietic development might be quite different between human and mouse, and that hFlt3 signaling may especially play a critical role in maintenance of long-term HSCs and in development of GM cells in human hematopoiesis.

Archives of Pathology & Laboratory Medicine 143, no. 2 (July 6, 2018): 212–21. http://dx.doi.org/10.5858/arpa.2017-0412-ra.
Full textAbstract:
Context.— Pleomorphic hyalinizing angiectatic tumor (PHAT) of soft parts, hemosiderotic fibrolipomatous tumor (HFLT), and myxoinflammatory fibroblastic sarcoma (MIFS) are 3 distinct entities of low-grade spindle cell mesenchymal neoplasm. These tumors have similar clinical presentations and partially overlapping but distinctive pathologic features. A recurrent translocation, t(1;10)(p22;q24), has been detected in a subset of PHAT, HFLT, MIFS, and HFLT/MIFS hybrid cases. Translocation t(1;10)(p22;q24) involves transforming growth factor β-receptor 3 (TGFBR3) and meningioma-expressed antigen 5 (MGEA5) genes on chromosomes 1p22 and 10q24, respectively. However, the percentage of translocation in PHAT, HFLT, and MIFS varies significantly among different studies. The relationship among these tumors has been a controversial topic among experts. Objective.— To discuss the diagnostic and functional significance of translocation t(1;10)(p22;q24) TGFBR3/MGEA5 rearrangement in HFLT, PHAT, and MIFS. Data Sources.— PubMed was used for this study. Conclusions.— Diagnosis of HFLT, PHAT, and MIFS is challenging because of a lack of unique morphologic, immunophenotypic, molecular, and cytogenetic markers. The recurrent t(1;10)(p22;q24) translocation and/or TGFBR3/MGEA5 rearrangement was reported in 55 patients, with a relatively even distribution among HFLT, PHAT, and MIFS (17 HFLT, 15 MIFS, 13 MIFS/HFLT, and 10 PHAT). This indicates that current morphology-based diagnostic criteria do not identify reliably the subset of soft tissue tumor with t(1;10) translocation. Genetic heterogeneity of these tumors is supported by the recent detection of a mutually exclusive, second recurrent genetic change, t(7;17) TOM1L2-BRAF translocation or BRAF amplification, in a subset of MIFS.

Full textAbstract:
Abstract Flt3/Flt3-ligand has a non-redundant role in dendritic cell (DC) and interferon producing cell (IPC) development from hematopoietic progenitor cells. Flt3-ligand−/− mice display a severe reduction of DCs and IPCs, and both, Flt3-ligand injection and conditional over- expression of Flt3-ligand in mice leads to an increased pool size of both cellular subsets. Furthermore, DC and IPC developmental precursor activity segregates with Flt3+ progenitor populations in mouse bone marrow. We have reported that common myeloid progenitors (CMPs) and their progeny granulocyte/macrophage progenitors (GMPs) as well as common lymphoid progenitors (CLPs) and pro-T cells can give rise to DCs in vitro and in vivo. DC developmental potential was lost, however, once definitive megakaryocyte/erythrocyte or B cell commitment occurs, both steps that are accompanied by loss flt3 receptor expression. To test if DC/IPC developmental potential can be regained, we evaluated the effect of ecotropic expression of human Flt3 in lin−c-kit+Flt3−Thy1.1−IL-7Ra− cells (flt3− progenitors) and in megakaryocyte/erythrocyte progenitors (MEPs). hFlt3 was transduced into purified flt3− progenitors, MEPs, and GMPs using a retrovirus vector carrying both hFlt3 and GFP. The transduction efficiencies were 20~25%. hFlt3-transduced flt3− progenitors gave rise to functional DCs and IPCs, but not control-GFP-transduced flt3− progenitors in vitro. Similarly, hFlt3-transduced MEPs differentiated into functional DCs in Flt3L, SCF, GM-CSF, IL-4, and TNF-a supplemented cultures but not into TER119+ erythroid cells. DC developmental potential of hFlt3-transduced MEPs was comparable to GFP-transduced GMPs. Over expression of hFlt3 in GMPs resulted in augmentation of its DC developmental potential. Interestingly, both hFlt3-tarnsduced MEPs and GMPs preferentially differentiated into IPCs in Flt3L supplemented medium. RT-PCR analysis revealed that enforced Flt3 signaling in MEPs lead to up-regulation of GM- and/or DC-development affiliated genes such as G-CSF receptor, M-CSF receptor, and GM-CSF receptor, PU.1, C/EBPa and STAT3. Furthermore, hFlt3-transduced MEPs gave rise to myeloid colonies (CFU-GM/G/M) but not CFU-Mix colonies in GM-CSF, IL-3, SCF, Flt3L, Tpo, and Epo supplemented methylcellulose medium. These results show that artificial Flt3 signaling in otherwise Flt3− progenitors is sufficient to reestablish DC/IPC differentiation and GM-differentiation programs.

Full textAbstract:
AbstractAlthough the effects of dietary fat and carbohydrate on satiety are well documented, little is known about the impact of these macronutrients on food hedonics. We examined the effects ofad libitumand isoenergetic meals varying in fat and carbohydrate on satiety, energy intake and food hedonics. In all, sixty-five overweight and obese individuals (BMI=30·9 (sd3·8) kg/m2) completed two separate test meal days in a randomised order in which they consumed high-fat/low-carbohydrate (HFLC) or low-fat/high-carbohydrate (LFHC) foods. Satiety was measured using subjective appetite ratings to calculate the satiety quotient. Satiation was assessed by intake atad libitummeals. Hedonic measures of explicit liking (subjective ratings) and implicit wanting (speed of forced choice) for an array of HFLC and LFHC foods were also tested before and after isoenergetic HFLC and LFHC meals. The satiety quotient was greater afterad libitumand isoenergetic meals during the LFHC condition compared with the HFLC condition (P=0·006 andP=0·001, respectively), whereasad libitumenergy intake was lower in the LFHC condition (P<0·001). Importantly, the LFHC meal also reduced explicit liking (P<0·001) and implicit wanting (P=0·011) for HFLC foods compared with the isoenergetic HFLC meal, which failed to suppress the hedonic appeal of subsequent HFLC foods. Therefore, when coupled with increased satiety and lower energy intake, the greater suppression of hedonic appeal for high-fat food seen with LFHC foods provides a further mechanism for why these foods promote better short-term appetite control than HFLC foods.

Full textAbstract:
Sysmex XN-1000 hematology analyzer is an automated 5-part diff analyzer (eosinophils, basophils, neutrophils, lymphocytes, and monocytes). In the calculated area, the type of difference between the Sysmex hematology device and other hematology devices is Immature Granulocyte (IG), Nucleated Red Blood Cell (NRBC), and High Fluorescent Lymphocytes Count (HFLC). The cells calculated in the HFLC area are atypical lymphocytes. In patients with dengue hemorrhagic fever, it is often found atypical lymphocytes called blue plasma lymphocytes. The purpose of this study was to determine the description of HFLC in patients with dengue fever using the hematology analyzer Sysmex XN-1000. A descriptive retrospective study was conducted during April-May 2017. The subjects of the study were adult patients diagnosed with dengue hemorrhagic fever with WHO criteria. Of the 47 samples of Dengue Hemorrhagic Fever (DHF) patients, the average HFLC results were between 2.0-32.3%, which was 11.5%, while the average range of normal HFLC values was between 0.0-1.4% and was 0.3%. In cases of DHF, there is an increase in HFLC. This is likely to be attributed to atypical lymphocyte increase in dengue hemorrhagic fever. Further research with more varied samples still needs to be done.

Full textAbstract:
Mutations in FGF23, KL, and GALNT3 have been identified as the cause for the development of hyperphosphatemic familial tumoral calcinosis (HFTC). Patients with HFTC typically present in childhood or adolescence with periarticular soft tissue deposits that eventually progress to disrupt normal joint articulation. Mutations in the GALNT3 gene were shown to account for the hyperphosphatemic state in both HFTC and hyperostosis-hyperphosphatemia syndrome (HHS), the latter characterized by bone involvement. We present the case of a patient of a Druze ethnic origin with known HFTC that presented to our department with the first documented case of pathologic fracture occurring secondary to the disease. Our report introduces this new phenotypic presentation, suggests a potential role for prophylactic bone screening, and highlights the need for preconception genetic screening in selected populations.

Full textAbstract:
We use thermal conductivity to study a unique state in the high field corner of the superconducting phase of CeCoIn5. The spin-density-wave (SDW) magnetic order in this high field low temperature (HFLT) phase requires superconductivity for its very existence, and both magnetism and superconductivity disappear together at superconducting critical field H[Formula: see text]. We measured thermal conductivity of CeCoIn5 in a rotating magnetic field to study the nature of the HFLT phase. Our measurements reveal the presence of an additional order inside the HFLT phase that is intimately intertwined with the superconducting [Formula: see text]-wave and the SDW orders, which we identify as a superconducting [Formula: see text]-wave pair-density-wave (PDW). CeCoIn5 displays a hierarchy of interactions within the HFLT phase, where spin–orbit coupling orients the SDW, which then determines orientation of the secondary PDW component.

Purpose. To assess the feasibility, acceptability, and efficacy of a text message–based smoking cessation intervention in China. Design. Study design was a randomized control trial with a 6-month follow-up assessment of smoking status. Setting. Zhejiang, Heilongjiang, and Shaanxi provinces in China provided the study setting. Subjects. A total of 8000 adult smokers in China who used Nokia Life Tools and participated in phase 2 (smoking education via text message) of the study were included. Intervention. The high-frequency text contact (HFTC) group received one to three messages daily containing smoking cessation advice, encouragement, and health education information. The low-frequency text contact (LFTC) group received one weekly message with smoking health effects information. Measures. Our primary outcome was smoking status at 0, 1, 3, and 6 months after intervention. Secondary outcomes include participant perceptions of the HFTC intervention, and factors associated with smoking cessation among HFTC participants. Analysis. Descriptive and χ2 analyses were conducted to assess smoking status and acceptability. Factors associated with quitting were assessed using multiple logistic regression analyses. Results. Quit rates were high in both the HFTC and LFTC groups (HFTC: 0 month, 27.9%; 1 month, 30.5%; 3 months, 26.7%; and 6 months, 27.7%; LFTC: 0 month, 26.7%; 1 month, 30.4%; 3 months, 28.1%; and 6 months, 27.7%), with no significant difference between the two groups in an intent-to-treat analysis. Attitudes toward the HFTC intervention were largely positive. Conclusion. Our findings suggest that a text message–based smoking cessation intervention can be successfully delivered in China and is acceptable to Chinese smokers, but further research is needed to assess the potential impact of this type of intervention.

AbstractHuman neurocysticercosis (NCC) is a worldwide neglected disease caused by Taenia solium metacestode and responsible for various complications and neurological disorders. This study aimed to evaluate the use of specific immunoglobulin Y (IgY) produced by laying hens immunized with a hydrophobic fraction of Taenia crassiceps metacestodes (hFTc) in NCC diagnosis. Egg yolk IgY antibodies were fractionated, purified and characterized. Enzyme-linked immunosorbent assay (ELISA) was carried out to evaluate the production kinetics and avidity maturation of anti-hFTc IgY antibodies throughout the IgY obtention process. Antigen recognition tests were carried out by Western blotting and immunofluorescence antibody test using purified and specific anti-hFTc IgY antibodies for detection of parasitic antigens of T. crassiceps and T. solium metacestodes. Sandwich ELISA was performed to detect circulating immune complexes formed by IgG and parasitic antigens in human sera. The results showed high diagnostic values (93.2% sensitivity and 94.3% specificity) for immune complexes detection in human sera with confirmed NCC. In conclusion, specific IgY antibodies produced from immunized hens with hFTc antigens were efficient to detect T. solium immune complexes in human sera, being an innovative and potential tool for NCC immunodiagnosis.

Purpose Selecting the most appropriate healthcare waste treatment technology (HCWTT) is an uncertain and complex decision-making problem because there exist more than one alternative and many conflicting qualitative and quantitative criteria. However, the use of fuzzy and comparative values, instead of specific crisp values, provides more accurate results, so that the alternatives may be evaluated in accordance with hesitant human nature. The purpose of this paper is to select the best HCWTT using a hesitant fuzzy linguistic term set (HFLTS). Design/methodology/approach Five main criteria were identified for HCWTT selection, such as economic, social, environmental, technical and ergonomic criteria. In total, 19 sub-criteria were examined, and the hierarchy of the criteria was formed. The criteria weights were determined using the multi-criteria hesitant fuzzy linguistic term set (MC-HFLTS). The selection processes of incineration (A1), steam sterilization (A2), microwave (A3) and landfill (A4) alternatives were carried out using the multi-attributive ideal-real comparative analysis (MAIRCA) and multi-attributive border approximation area comparison (MABAC) methods. In the comparative analyses, Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) and technique for order preference by similarity to an ideal solution (TOPSIS) methods were used. Findings The comparison of the results of the MABAC and MAIRCA methods with the results of VIKOR and TOPSIS methods indicated that A2 (steam sterilization) alternative was the best one and produced the same ranking of the technology alternatives (A2 > A3 > A1 > A4). As a result, the study concluded that these methods can be successfully used for HCWTT selection problems. Originality/value To the best of the authors’ knowledge, MC-HFLTS has not been used to select HCWTT in the existing literature. For the first time, MC-HFLTS&MAIRCA and MC-HFLTS&MABAC approaches were used in order to choose the best treatment method for healthcare waste under the effect of multiple conflicting hierarchical criteria. It has been provided that MABAC and MAIRCA select alternative choices by taking into consideration the hierarchical criteria. Unlike other studies, this study also considered ergonomic criteria that are important for people working during the process of using the treatment technology.

Increasing development of the relationship between Vietnam and other
countries has resulted in a great demand for English language teaching (ELT)
throughout the country. The need is ever greater for a considerable number
of people who can use English effectively in their work. However, at present
ELT in Vietnam is still far from satisfactory. There exists a common problem
of communicative incompetence in Vietnamese learners. ELT in the Hanoi Foreign Languages Teachers' College (HFLTC) is taken to illustrate the fact
that even after five years of training, students frequently remain deficient in
the ability to actually use the language, to understand its use in normal
communication, and to carry out their teaching adequately afterwards.
That existing situation demands a critical look at ELT in all institutions to
work out suitable materials and methods to be used in the Vietnamese setting.
This work has been undertaken as an exploratory study of this problem. To
provide a context for the study, the background to ELT in Vietnam is
reviewed. Following it is a detailed description of different approaches used
in ELT with reference to the teaching and learning situations in Vietnam.
Special emphasis is placed on the differences between conventional
approaches and the currently influential one - the Communicative Approach.
A detailed comparison is made between two lessons taken from structuralbased
and functional/notional-based textbooks representing two distinct
approaches. This comparison will be examined from the methodological point
of view, investigating, for example, how language is treated in the two
approaches, how different types of activities are used, and the role of teacher
and learner in the two approaches in order to highlight a possible fresh
approach for Vietnamese coursebook designers, teachers and learners in ELT.
A sample lesson based on the Communicative Approach is finally provided to
assist any attempts to teach and learn English communicatively.
It is hoped that this survey will contribute to reducing the existing problem
of inadequate communicative competence in Vietnamese learners.

In Vietnam today there is an urgent demand for well-designed tests
of listening comprehension. Little attention has been given to this
problem. This field study is intended to provide guidance on the
design of listening comprehension tests and in particular for
intermediate level students at the Hanoi Foreign Language College
(HFLC).
The Field Study Report consists of six chapters. Chapter One gives a
brief introduction which covers the problem, aims, subjects
(testees) and the background of the Field Study Report.
Chapter Two deals with the purposes of testing in some detail,
setting this in the framework of the teaching-testing link, teachers
and testing, and students and testing. Test characteristics are
considered and the problem of sampling for test content is addressed.
Chapter Three concerns test items for listening comprehension. The
chapter begins with a short description of listening comprehension
and is followed by a survey of theorists on listening comprehension
together with the test items for listening that they suggest. Some
commonly-used standardised tests and their listening items are
discussed.
The chapter ends with a checklist of selected listening items
suitable for students at HFLC in Vietnam.
Chapter Four discusses the designing and trialling of test items for
listening comprehension, such as multiple choice, completion of a
taped talk, matching pictures with statements etc. The chapter
presents the results of the trialling of sample items and also deals
with correlations between the sample tests used.
Chapter Five deals with test design and development in general. It
clarifies the bases for test design and provides a checklist of
steps in the development of tests. In addition, the chapter includes
a resources inventory for listening test items.
Chapter Six presents the conclusions of the Field Study Report.

There is a great need for competent teaching of Business
English in tertiary institutions in Vietnam.
At the Hanoi Foreign Trade College (HFTC) alone, about 150
students per year seek training to equip them to work in export
and import organizations, banks for foreign trade and customs
departments.
In teaching such students, one problem is the provision of
interesting and relevant materials. This study addresses the
question of selection of materials and techniques for teaching
business English listening skills.
This Field Study Report consists of five chapters. Chapter 1
describes the purposes and aims of study, the background to
this study, dealing with students, the teaching and the
curriculum.
Chapter 2 looks at the general theory about listening and in
particular listening in business. The chapter also describes
listening requirements for business graduates from the HFTC.
Chapter 3 discusses criteria for selection of textbooks for
language teaching in general and for teaching listening skills
in business English in particular.
Chapter 4 surveys the teaching of business English in two
institutes of Technical and Further Education in the Australian
Capital Territory (ACT).
The final chapter makes suggestions for priorities to improve
the teaching of business English.
This Field Study Report should be regarded as an exploratory
attempt in choosing classroom techniques and materials for
teaching listening skills to students of commerce at the Hanoi
Foreign Trade College.

This study examines the problems of constructing and
administering a test of spoken English for Vietnamese EFL teacher-trainees. In
an attempt to standardize the assessment, a planned oral interview was pilottested
with a group of ten Vietnamese EFL teachers currently enrolled in a
Graduate Diploma Course in TESOL at the Canberra College of Advanced
Education, Australia. Results of the study indicate that the validity and reliability
of such measurement can be achieved if certain carefully outlined procedures in
planning the test and training the testers are carefully followed.
Given the close relationship between testing and teaching, it is
suggested in this study that there could be an improvement in the teaching of
spoken English to Vietnamese EFL teacher-trainees if (i) the amount of time
allocated to testing oral proficiency in the curriculum was increased, (ii)
Vietnamese EFL teachers were provided with formal training in language test
construction, and (iii) research on EFL oral testing was encouraged. Further,
this study recommends co-operation between TEFL institutions in Vietnam to
develop standard instruments for the assessment of spoken English of EFL
teacher-trainees on a national level.

The English language occupied a specially
important status in the increasing development of science,
technology, culture and international relations in Vietnam,
which has resulted in a growing demand for English Language
Teaching (ELT) all over the country. The Hanoi Foreign
Languages Teachers' Training College in general and its
Department of English in particular plays a very important
role in this by producing as many teachers of English as
possible for high schools as well as for other Colleges and
Universities in Vietnam as a whole. Unfortunately, ELT in
Vietnam is still far from satisfactory. There exists a common
problem of communicative competence in Vietnamese students,
even in Vietnamese teachers of English. ELT at HFLTTC is
taken to illustrate the fact that even after five years'
training, graduates remain deficient in the ability of
language use as well as understanding its use in normal
communication. This being the case, how can they carry out
effectively the teaching of English to high school pupils or
students at other institutions?
In this situation, we need to take a serious look
at ELT in the Department of English at the HFLTTC so as to
suggest suitable materials and methods which will enable the
Institution to function more effectively.
This project makes an exploratory study of the
problem. To provide a context for the study, the background
to ELT in the Department of English is reviewed. This is
followed by a detailed description of different approaches
used in ELT with the reference to the actual activities of
teaching and learning in the Department of English. A special
emphasis is placed on the difference between conventional
approaches and the currently influential one - The Functional-
Notional-Approach to language teaching and learning. The
basic notions of this approach will be covered and also
different categories of functions and categories of
situations which the students of English often encounter in
using English. Different techniques of teaching functional
spoken English will be suggested with an aim to improving the
teaching of spoken English in the above-mentioned setting.
It is hoped that this project may become a
contribution to solving some of the existing problems of
inadequate communicative competence of Vietnamese students of
English and to teaching and learning English with effective
communication skills in the Department of English at the
HFLTTC.

A Pseudomonas strain TeU resistant to tellurite (TeO32-) and cadmium (Cd2+) ions was isolated from heavy-metal contaminated sediments by enrichment. Transposon mutagenesis of strain TeU resulted in mutants exhibiting Cd2+ sensitivity (Strain BU21) and one with decreased ability to reduce tellurite (strain AU08). Genes encoding an HflKC complex and an putative metallopeptidase were identified to be associated with the bacterium’s ability for tellurite reduction and cadmium resistance, respectively. We have cloned and sequenced the hflC and metallopeptidase gene of strain TeU. Metallopeptidase gene of strain TeU was cloned and expressed in E. coli in order to investigate if the protein could improve the bacterium’s ability to resist cadmium.Transmission electron microcopy was also employed for to observe metal precipoitation when strain TeU grown in the medium containing tellurite.

Mestrado APNOR e de dupla diplomação com a UTFPR - Universidade Tecnológica Federal do ParanáA indústria 4.0 compreende a aplicação de diferentes soluções tecnológicas de modo que os processos de negócios em toda a cadeia produtiva sejam integrados. A realização da seleção de fornecedores considerando os requisitos da indústria 4.0 é essencial na promoção de estratégias colaborativas entre fornecedores e fabricantes. Nesse enquadramento, por meio de uma revisão sistemática, foram caracterizados os estudos que propuseram modelos quantitativos para apoiar a seleção de fornecedores no contexto da indústria 4.0. No entanto, não foram encontrados modelos que empreguem critérios de avaliação de fornecedores relacionados a requisitos advindos da indústria 4.0, e que consideram a dificuldade de coletar dados para medir o desempenho dos fornecedores. Assim sendo, a fim de preencher a lacuna de pesquisa identificada, este estudo propõe um modelo de decisão para apoiar a seleção de critérios e fornecedores, com base na combinação de Hesitant Fuzzy Linguistic Term Set (HFLTS) com o método Quality Function Deployment (QFD) considerando um conjunto de critérios definidos a partir de requisitos advindos da indústria 4.0. Para isso, um modelo computacional foi desenvolvido no MS Excel e aplicado em um caso ilustrativo utilizando dados simulados. Por meio dos resultados da aplicação, é possível constatar a capacidade do método em apoiar a tomada de decisão em grupo e considerar pesos diferentes para os julgamentos dos decisores na escolha dos critérios e na avaliação dos fornecedores. A sensibilidade nos parâmetros de saída do modelo às alterações nos parâmetros de entrada sugere efetividade do modelo proposto.
Industry 4.0 comprises the application of different technological solutions so that business processes throughout the integrated production chain. Carrying out the selection of suppliers considering the requirements of industry 4.0 is essential in the promotion of collaborative collaborators between suppliers and manufacturers. In this context, through a systematic review, studies were characterized that proposed quantitative models to support the selection of suppliers in the context of industry 4.0. However, no models were found that use supplier evaluation criteria related to requirements arising from industry 4.0, and which consider it a difficulty to collect data to assess supplier performance. Therefore, in order to fill an identified research gap, this study proposes a decision model to support a selection of criteria and suppliers, based on the combination of Hesitant Fuzzy Linguistic Term Set (HFLTS) with the Quality Function Deployment (QFD) method considering a set of criteria defined from the requirements arising from industry 4.0. For this, a computational model was developed in MS Excel and applied in an illustrative case using simulated data. Through the results of the application, it is possible to verify the capacity of the method to support group decision making and consider different weights for the judgments of decision makers in the choice of criteria and in the evaluation of suppliers. The sensitivity of the model's output parameters to changes in the input parameters, the effectiveness of the proposed model.

Systems such as robotic systems and systems with large input-output data tend to be difficult to model using mathematical techniques. These systems have typically high dimensionality and have degrees of uncertainty in many parameters. Artificial intelligence techniques such as neural networks, fuzzy logic, genetic algorithms and evolutionary algorithms have created new opportunities to solve complex systems. Application of fuzzy logic [Bai, Y., Zhuang H. and Wang, D. (2006)] in particular, to model and solve industrial problems is now wide spread and has universal acceptance. Fuzzy modelling or fuzzy identification has numerous practical applications in control, prediction and inference. It has been found useful when the system is either difficult to predict and or difficult to model by conventional methods. Fuzzy set theory provides a means for representing uncertainties. The underlying power of fuzzy logic is its ability to represent imprecise values in an understandable form. The majority of fuzzy logic systems to date have been static and based upon knowledge derived from imprecise heuristic knowledge of experienced operators, and where applicable also upon physical laws that governs the dynamics of the process. Although its application to industrial problems has often produced results superior to classical control, the design procedures are limited by the heuristic rules of the system. It is simply assumed that the rules for the system are readily available or can be obtained. This implicit assumption limits the application of fuzzy logic to the cases of the system with a few parameters. The number of parameters of a system could be large. The number of fuzzy rules of a system is directly dependent on these parameters. As the number of parameters increase, the number of fuzzy rules of the system grows exponentially. Genetic Algorithms can be used as a tool for the generation of fuzzy rules for a fuzzy logic system. This automatic generation of fuzzy rules, via genetic algorithms, can be categorised into two learning techniques, supervised and unsupervised. In this paper unsupervised learning of fuzzy rules of hierarchical and multi-layer fuzzy logic control systems are considered. In unsupervised learning there is no external teacher or critic to oversee the learning process. In other words, there are no specific examples of the function to be learned by the system. Rather, provision is made for a task-independent measure of the quality or representation that the system is required to learn. That is the system learns statistical regularities of the input data and it develops the ability to learn the feature of the input data and thereby create new classes automatically [Mohammadian, M., Nainar, I. and Kingham, M. (1997)]. To perform unsupervised learning, a competitive learning strategy may be used. The individual strings of genetic algorithms compete with each other for the “opportunity” to respond to features contained in the input data. In its simplest form, the system operates in accordance with the strategy that ‘the fittest wins and survives’. That is the individual chromosome in a population with greatest fitness ‘wins’ the competition and gets selected for the genetic algorithms operations (cross-over and mutation). The other individuals in the population then have to compete with fit individual to survive. The diversity of the learning tasks shown in this paper indicates genetic algorithm’s universality for concept learning in unsupervised manner. A hybrid integrated architecture incorporating fuzzy logic and genetic algorithm can generate fuzzy rules for problems requiring supervised or unsupervised learning. In this paper only unsupervised learning of fuzzy logic systems is considered. The learning of fuzzy rules and internal parameters in an unsupervised manner is performed using genetic algorithms. Simulations results have shown that the proposed system is capable of learning the control rules for hierarchical and multi-layer fuzzy logic systems. Application areas considered are, hierarchical control of a network of traffic light control and robotic systems. A first step in the construction of a fuzzy logic system is to determine which variables are fundamentally important. Any number of these decision variables may appear, but the more that are used, the larger the rule set that must be found. It is known [Raju, S., Zhou J. and Kisner, R. A. (1990), Raju G. V. S. and Zhou, J. (1993), Kingham, M., Mohammadian, M, and Stonier, R. J. (1998)], that the total number of rules in a system is an exponential function of the number of system variables. In order to design a fuzzy system with the required accuracy, the number of rules increases exponentially with the number of input variables and its associated fuzzy sets for the fuzzy logic system. A way to avoid the explosion of fuzzy rule bases in fuzzy logic systems is to consider Hierarchical Fuzzy Logic Control (HFLC) [Raju G. V. S. and Zhou, J. (1993)]. A learning approach based on genetic algorithms [Goldberg, D. (1989)] is discussed in this paper for the determination of the rule bases of hierarchical fuzzy logic systems.
