Authors: Royer Rogério , Porto Rosa Ariane Ferreira , Dos Santos Lucas Nienow
Published: March 2017

A produção enxuta propõe a simplificação do processo produtivo através da eliminação das perdas. Para tanto, torna-se necessária a visualização processo produtivo, a compreensão de suas etapas e do fluxo de materiais a fim de identificar as perdas. O Mapa de Fluxo de Valor (MFV) tem se mostrado uma ferramenta importante do sistema de produção enxuta usada para a identificação e eliminação de desperdícios. No MFV a fabricação do produto é representada por seus processos produtivos dispostos em sequência para a obtenção da visibilidade do processo produtivo a fim de simplificá-lo. Este artigo apresenta uma revisão teórica, onde são descritos alguns conceitos e definições da produção enxuta, do MFV, bem como as ferramentas utilizadas. O artigo apresenta um estudo de caso realizado em uma indústria metalúrgica. No estudo de caso o fluxo do material e das informações foi mapeado, de forma a identificar os desperdícios, bem como a fonte dos mesmos no fluxo de valor. Após a identificação dos gargalos, elaborou-se o mapa do “estado futuro” mostrando-se como o valor deve fluir, e criando-se um plano de ação para tornar efetivas as propostas de melhorias.

Published: March 2017

A necessidade de métodos de avaliação de desempenho em gestão da produção, bem como a possibilidade de inserção de pesquisas científicas nas organizações fabris, motivaram a elaboração deste estudo. O presente artigo tem como objetivo identificar lacunas e propor uma agenda de pesquisa sobre avaliação de desempenho na gestão da produção. O método de intervenção utilizado para o desenvolvimento da pesquisa foi o Proknow-C, Knowledge Development Process-Constructivist. Como resultado de pesquisa, foi possível identificar um portfólio bibliográfico de 11 artigos, além de evidenciar os periódicos, autores e palavras-chave mais relevantes por meio da análise bibliométrica permitindo tecer uma análise crítica descritiva, das seis lentes propostas pela metodologia. E como principal resultado foi reconhecido que a metodologia Proknow-C, se mostrou relevante como instrumento de intervenção no auxílio para a construção do conhecimento. Além disso, na análise sistêmica, foi percebida a necessidade de reconhecimento do decisor como importante elemento na elaboração dos critérios e também da falta de métodos de integração dos resultados, no qual emergiram algumas oportunidades de pesquisa.

Authors: Callefi Mario Henrique Bueno Moreira , Chiroli Daiane Maria de Genaro
Published: March 2017

O mercado da comunicação visual está cada mais competitivo, gerando assim a necessidade de apresentar preços mais competitivos e possuir padrões de qualidade que estejam de acordo com os requisitos da qualidade impostos pelo mercado. Dessa maneira para as empresas conseguirem sobreviver no mercado atual é necessário que os custos sejam reduzidos, principalmente com as atividades que não agregam valor junto ao cliente, como é o caso das ocorrências de não conformidades. O presente trabalho por meio da utilização da Metodologia de Análise e Solução de Problemas (MASP), com base na etapa de planejamento do ciclo PDCA, objetivou-se em analisar as ocorrências de retrabalhos e permitir a elaboração de um plano de ação para a resolução desse problema. Ferramentas da qualidade como o 5W1H, gráfico de Pareto, diagrama de causa e efeito foram empregadas como apoio para o uso do MASP. Como resultado foi desenvolvido um plano de ação que permitirá que a empresa direcione suas atividades com foco na melhoria contínua e na eliminação de seus problemas de qualidade.
PROPOSIÇÃO DE UM MODELO MULTIFATORIAL PARA MENSURAÇÃO DA SATISFAÇÃO DE CONSUMIDORES DO VAREJO SUPERMERCADISTA
Authors: Dos Santos José Wendel
Published: March 2017

O objetivo deste estudo foi propor um modelo multifatorial para mensuração da satisfação de consumidores do varejo supermercadista. O desenvolvimento do modelo proposto foi sistematizado em cinco etapas: revisão da literatura; pesquisa em profundidade com informantes-chaves; estruturação preliminar do modelo; operacionalização do modelo; e análise estatística dos dados provenientes de sua aplicação. Os resultados obtidos demonstraram que o modelo possui uma estrutura composta por 31 atributos agrupados em cinco fatores: atmosfera da loja; produto; atendimento; conveniência e facilidades; e segurança. Estes fatores juntos explicaram 89,07% (expectativa) e 91,29% (percepção) da variabilidade dos dados originais, além de apresentarem consistência interna significativa, pois todos os coeficientes alfa de Cronbach encontrados superaram o limite mínimo de satisfatoriedade. Operacionalmente, o modelo proposto se mostrou eficiente, pois as informações adquiridas a partir de sua aplicação em um supermercado possibilitou a formulação de estratégias gerenciais para a melhoria na prestação dos serviços e a manutenção da satisfação dos consumidores.
Entre blessures de guerre et guerre des blessures : la « balle humanitaire » en débat en Europe et au Japon, 1890-1905
Authors: Daimaru Ken
Published: March 2017

L’histoire de la « balle humanitaire » permet de poser un nouveau regard sur les transformations de la médecine militaire et de la représentation des blessures de guerre à l’orée du XX e  siècle. À partir d’une approche croisée, en Europe et au Japon, du débat médical sur l’évolution des propriétés balistiques des nouvelles armes à feu, ce texte analyse l’émergence et le développement d’un groupe de médecins experts en « balistique lésionnelle ». Ces professionnels participent, au sein des appareils militaires, à l’anticipation des atteintes corporelles et à l’optimisation des effets du feu, dans un but à la fois curatif et vulnérant. Ainsi les médecins collaborent aux dégâts qu’ils contribuent par vocation à réparer. Nous explorons dans cet article le caractère problématique du concept de « balle humanitaire » et l’appropriation par les acteurs médicaux européens et japonais des dispositifs militaires produits dans le « monde civilisé ». Enfin, nous discutons de la mise en débat public de ces questions, autour de la controverse des balles dum-dum et de la « guerre des blessures ».
Aux fondements introuvables de l’État-providence : la loi du 9 avril 1898 à l’épreuve de la Grande Guerre
Authors: Viet Vincent
Published: March 2017

La loi du 9 avril 1898 est souvent présentée comme le socle fondateur de la législation des accidents du travail, qui aurait défié le temps moyennant des aménagements de pure commodité. Sa pérennisation justifierait qu’on l’étudie isolément. En réalité, ce texte a influencé d’autres législations et produit des excroissances juridiques, garantes de sa longévité. La Grande Guerre en offre une illustration, qui a vu cette loi devenir un élément clé du statut de la main-d’œuvre mobilisée ; servir de ressource juridique au calcul des pensions et gratifications militaires ; enfin, s’hybrider avec l’assistance militaire pour assurer l’indemnisation des mutilés de guerre accidentés du travail. D’où l’intérêt de revenir sur les relations entre la réparation civile des accidents du travail et la réparation militaire des infirmités et des maladies de guerre, qui permettent de comprendre pourquoi l’État-providence n’est pas né de cette loi ni, curieusement, des décombres de la guerre.
Nathalie St/G-R-Anger et l’inquiétante étrangeté de la maison des femmes
Authors: Meyer zum Wischen Michael
Published: March 2017

En 1972, Marguerite Duras écrivit le scénario d’un film intitulé Nathalie Granger . La même année, Jacques Lacan commença son séminaire novateur Encore sur la sexualité féminine. Il est frappant que Marguerite Duras, qui tourna le film dans sa propre maison, en vint à la qualifier en employant des mots comme « étrange » et « inquiétante ». Cet article essaie, en se servant du scénario de Marguerite Duras, d’approfondir le concept freudien d’« inquiétante étrangeté » eu égard aux élaborations du dernier Lacan. Quant aux femmes, Duras parle « de cette fonction, submergeante, d’enfouissement du discours en un lieu où il s’annule, se tait , se supprime ». On peut comparer cette phrase à une énonciation de Lacan dans Encore où il dit : «  S’il y en avait une autre, mais il n’y en a pas d’autre que la jouissance phallique – sauf celle sur laquelle la femme ne souffle mot, peut-être parce qu’elle ne la connaît pas, celle qui la fait pas-toute. »
L’adolescent et le couple de ses parents
Authors: Louchard Chardon Christine , Morhain Yves
Published: March 2017

À l’adolescence des enfants, et lors de leur passage à l’âge adulte, la solidité du lien de couple est mise à l’épreuve. Les conflits, bien souvent présents à bas bruit, prennent de l’ampleur. Les auteurs mettent en évidence en quoi le lien conjugal est à cette période mobilisé et en quoi cette mobilisation conduit à un réaménagement des alliances et pactes inconscients. Les conflits entre parents sont entendus comme une reprise par et dans le couple des processus de séparation-individuation. Ce déplacement est envisagé sous l’angle d’une latéralisation de la crise adolescente au couple des parents.
Perversion et psychose I Leurs différences et leurs interférences dans l’œuvre de Freud
Authors: Kaltenbeck Franz
Published: March 2017

Les trois structures cliniques – névroses, psychoses et perversions – ne se limitent pas à des tableaux cliniques. Elles posent plutôt des questions existentielles aux êtres parlants qui y sont pris. Ces structures ne se confondent pas. Mais elles peuvent interférer l’une dans l’autre. La perversion peut avoir des répercussions à un moment donné de la vie d’un(e) psychotique, sans qu’on puisse minimiser son incident à un « trait de perversion ». Ce fait observable nous a amené à relire Freud pour savoir ce qui, dans sa théorie, différencie la perversion de la psychose et ce qui les rapproche.
Ne me touche plus ou Rien ne va plus entre sexe, pouvoir et savoir
Authors: Watteau Diane
Published: March 2017

Nous tenterons de montrer que les liaisons entre les trois termes sexe, pouvoir, savoir dans la représentation des rapports entre les corps masculins et féminins ne cessent de se dénouer, de se renouer autour du tact et de la vue. Depuis la figure de Camille Claudel (qui veut tout nouer ensemble) jusqu’à la paralysie dans d’autres démarches artistiques (rien ne tient plus ensemble), nous nous attarderons sur une reterritorialisation violente d’un corps comme promesse grâce à Sigalit Landau ou comme mission dans une performance de Marina Abramović.
Image du corps et chirurgie bariatrique
Authors: Gault Caroline
Published: March 2017

Cet article s’intéresse aux conséquences psychiques de la chirurgie bariatrique au regard de l’image du corps, notamment dans les cas de bypass gastrique. Si les attentes des patients en ce qui concerne leur image future sont fortes, le vacillement rapide de l’image corporelle après l’opération nécessite qu’ils puissent subjectiver cet événement inscrit dans le corps. La question de la perte est ainsi centrale dans ces problématiques. Par ailleurs, les attentes des patients pour ce qui est de leur image future ne coïncident pas toujours avec les effets psychiques observés après l’opération en lien avec leur image corporelle. L’analyse des suivis de candidats à ce type de chirurgie dans un établissement hospitalier nous enseigne sur ce qui porte le désir de ces sujets, en surpoids parfois depuis leur enfance, et sur les capacités subjectives qui leur permettent d’assumer leur nouvelle image et ses conséquences dans leurs relations aux autres.
« Que moi »
Authors: Bourjot Aline
Published: March 2017

Amélie, jeune adolescente rencontrée lors d’une présentation clinique, perçoit douloureusement sa différence, sa mise à l’écart de sa famille sans pouvoir l’élaborer. Elle est restée dans une identification à sa mère telle une toute petite fille et évacue de son discours la rivalité fraternelle tout en l’agissant avec les plus jeunes qu’elle dans l’institution qu’elle fréquente. La question d’une construction du sujet selon une structure psychotique se pose du fait de la déficience de la fonction symbolique perceptible dans son discours, même si Amélie est aussi porteuse d’un handicap lié à une anomalie chromosomique.

Authors: Tuan Tran Manh , Duc Nguyen Thanh , Van Hai Pham , Son Le Hoang
Published: March 2017

In practical dentistry, dentists use their experience to examine dental X-ray images and to derive symptoms from patients for concluding possible diseases. This method is based solely on the own dentists' experience. Dental diagnosis from X-Ray images is proposed to support for dentists in their decision making. This paper presents an application of consultant system for dental diagnosis from X-Ray images based on fuzzy rule. Fuzzy rule was applied in many applications and has important role in computational intelligence, data mining, machine learning, etc. Based on a dental X-ray image dataset, we use Fuzzy C-Means to classify them into clusters and construct the rule set. Fuzzy Inference System is then used to evaluate the rules by three validity indices. These rules accompanied with symptoms from patients help dentists in diagnosing dental diseases. This method is implemented and experimentally validated on the real dataset of Hanoi Medical University Hospital, Vietnam against the related algorithms.

Published: March 2017

Dental health expenditures are a big part of general health expenditures. In Turkey, oral health services are provided by both private practitioners and government sections. In 2012, approximately 7 million fillings were made by government clinics. According to Turkish Dental Association data, in the same year, the number of fillings that Turkish citizens needed was 247 million. Even if the entire budget of the Health Ministry of Turkey were spent for these fillings, it is impossible to handle this demand. In 2012, in the European Union with 24 member countries, dental health spending was close to 74 billion Euro. Because of this financial burden, Turkey and the other countries are trying to find cost-effective methods to minimize dental health spending. This chapter emphasizes dental health conditions of both Turkey and European Union, firstly, and then successful and cost-effective strategies are discussed.
Mastering Intellectual Property in Global Business
Authors: Kasemsap Kijpokin
Published: March 2017

This chapter reveals the overview of intellectual property (IP), the perspectives on intellectual property rights (IPRs), the importance of IP in global business, and the importance of IPRs in global business. IP is an asset category involving four distinct types (i.e., copyrights, trademarks, patents, and trade secrets). Many industries rely on the adequate enforcement of their copyrights, trademarks, and patents, while consumers utilize IP to ensure they are purchasing the guaranteed products. IPRs promote the confidence and ease of mind that consumers demand and markets rely on. Enforced IPRs ensure products are authentic, and of the high quality that consumers recognize and expect. The chapter argues that IP stimulates innovation and economic growth, as it helps bring in monetary returns, build brand visibility, and enhance business success in the digital age.

Multimodal Human Aerobotic Interaction
Authors: Abioye Ayodeji Opeyemi , Prior Stephen D , Thomas Glyn T , Saddington Peter , Ramchurn Sarvapali D
Published: March 2017

This chapter discusses HCI interfaces used in controlling aerial robotic systems (otherwise known as aerobots). The autonomy control level of aerobot is also discussed. However, due to the limitations of existing models, a novel classification model of autonomy, specifically designed for multirotor aerial robots, called the navigation control autonomy (nCA) model is also developed. Unlike the existing models such as the AFRL and ONR, this model is presented in tiers and has a two-dimensional pyramidal structure. This model is able to identify the control void existing beyond tier-one autonomy components modes and to map the upper and lower limits of control interfaces. Two solutions are suggested for dealing with the existing control void and the limitations of the RC joystick controller –the multimodal HHI-like interface and the unimodal BCI interface. In addition to these, some human factors based performance measurement is recommended, and the plans for further works presented.

Experiences with a Research Product
Authors: Børsting Jorun , Culén Alma Leora
Published: March 2017

This chapter discusses challenges related to studying the use and usefulness of research products (robust, high fidelity prototypes placed in real use contexts for research purposes). Methods and methodologies for studying use and usefulness of such research products embedded in users' everyday lives are still lacking and need to be better established. By presenting a case of such research product in use, a robot avatar, we wish to illustrate how new knowledge of relevance for both designers and users can be gained. The robot avatar was designed to represent chronically ill adolescents at school, improving his/hers learning opportunities, as well as helping maintain social connections with peers. The chapter shows how methods were adapted and tools designed to work with this user group and learn about the role of avatars in education and reduction of social isolation. The value of using the avatar, and similar research products, is considered.

We live in an ever-changing world. Despite that many new and excellent reforms are achieved, this period of time is also very confusing when many things that were regarded as concrete are becoming virtual. In spite of all this incompleteness, our common goal should be a good information society and the purpose of this chapter is to find out some factors that reveal the steps toward it. The question we ask is how to find a balance between a good life and eServices from the human point of view. The key findings pointed to issues in the needs of structural changes in the society. Another challenge that can be observed and which will be in the most essential role in the future, is the ownership and control over My Data. Agreements are a common practice in the business and when the subject is eServices in the future, we cannot avoid discussion of the end-user agreements, too.

Reflective Model and Proposition Development in Talent Management
Authors: Kumar Manoj
Published: March 2017

Talent Management (TM) has received lots of attention of academics, practitioners, researchers, scholars and competitive firms in recent years, but there are many gaps left for further theoretical and empirical development. One of gap is lack of clarity of definition of TM, and the ongoing debate about whether it is merely re-packaging of already existing HRM practices or a new concept. In this context, this chapter concludes that TM practices are distinct from the traditional HRM practices. The authors have consolidated the existing literature on talent management for designing integrated model of talent management including its antecedents and consequences. The study calls future research to empirically test the derived propositions. The chapter includes various theoretical, economic, managerial and future research implications.
Preparation of Magnetic Polylactic Acid Fiber Mats by Electrospinning
Authors: Kumar Manish , Unruh Daniel , Sindelar Ralf , Renz Franz
Published: March 2017

Poly(lactic acid) (PLA) is blended with Poly(ethylene glycol) (PEG) and magnetic nanoparticles (MNPs). A series of mixtures are converted to fibers via electrospinning at room temperature. The fiber diameter of PLA decreases on blending with PEG from 6 down to 3 micrometers and with PEG + MNPs down ca. 1 micrometer. The thermogravimetric study confirms the effect of blending, enhancing the stability on adding PEG to PLA. The magnetic properties of polymer fibers containing different concentrations of MNPs are studied by vibrating sample magnetometer. The fiber blends shows proportionally reduced saturation magnetization compared to pure magnetic nanoparticles. The MNPs –incorporated PLA-PEG nanocomposite mat show magnetization and therefore promise the possibility for temperature effects, such as hyperthermia treatment.

Published: March 2017

В работе рассматривается задача решения системы линейных уравнений с искаженной правой частью в следующей постановке. Известны случайная $m\times N$-матрица $A$ с элементами из $\{-1,1\}$ и вектор $xA+\xi\in \mathbf{R}^N$, где $\xi$ - вектор искажений из $\mathbf{R}^N$, элементы которого являются независимыми реализациями нормально распределенной случайной величины с параметрами $0$ и $\sigma^2$, а $x$ - случайный вектор с координатами из $\{-1,1\}$. Искомым параметром является вектор $x$. В работе предложен метод построения множества, содержащего искомый вектор с вероятностью не менее заданной, и оценена мощность этого множества. Теоретические расчеты параметров метода иллюстрируются результатами экспериментов, демонстрирующими практическую реализуемость метода при значениях параметров, не допускающих полный перебор всех возможных значений $x$.

Published: March 2017

Malaria incidence is highly heterogeneous even in areas of high transmission, although no conclusive evidence exists that innate or naturally acquired resistance can prevent infection over an extended period of time. This longitudinal study examined immunoparasitological evidence for a malaria-resistant phenotype in which children do not develop malaria despite an extended period of exposure to parasites. Within a birth cohort followed from 2002 to 2006 in Muheza, Tanzania, an area of intense transmission, children (N = 687) provided blood smears biweekly during infancy and monthly thereafter. Maternal and childhood characteristics were obtained, cord-blood cytokines were measured, and antibody responses were assayed as measures of stage-specific exposure. Sixty-three (9.2%) children had no blood smear–positive slides over 2 years of follow-up (range: 1–3.5 years) and were identified as malaria resistant. Malaria-resistant children were similar to other children with respect to completeness of follow-up and all maternal and childhood characteristics except residence area. Antibody seroprevalence was similar for two sporozoite antigens, but malaria-resistant children had a lower antibody seroprevalence to merozoite antigens merozoite surface protein 1 (5.4% versus 30.2%; P < 0.0001) and apical membrane antigen 1 (7.2% versus 33.3%; P < 0.0001). Malaria-resistant children had higher cytokine levels in cord blood, particularly interleukin-1β. In summary, a subset of children living in an area of intense transmission was exposed to malaria parasites, but never developed patent parasitemia; this phenotype was associated with a distinct cytokine profile at birth and antibody profile during infancy. Further research with malaria-resistant children may identify mechanisms for naturally acquired immunity.

Published: March 2017

Patients' delay in seeking diagnosis is a major problem in the management of tuberculosis (TB). Relative to the burden of TB, there is lack of data on the magnitude of delays in seeking care and why patients fail to seek early care at health facilities in Ethiopia. A facility-based cross-sectional study was conducted from April to July 2013 in East Gojjam Zone, Amhara, Ethiopia, to assess patients' delays and associated factors in TB patients. Using simple random sampling, 605 (327 male and 278 female) participants were recruited. Of the total, 323 (53.4%) TB patients were delayed in seeking health care (median = 45 days; mean = 78.5 days). The following independent variables were associated with patient delays: age ≥ 45 years (adjusted odds ratio [AOR] = 8.74, 95% confidence interval [CI] = 4.71–16.23, P < 0.001); working as a farmer (AOR = 4.18, 95% CI = 1.44–12.11, P = 0.009); prior visit to holy water sites, traditional healers, and/or private drug shops (AOR = 69.11, 95% CI =13.91–343.29, P < 0.001; AOR = 14.74, 95% CI = 1.43–152.31, P = 0.024; AOR = 2.10, 95% CI = 1.22–3.59, P = 0.007, respectively); poor knowledge about TB (AOR = 2.79, 95% CI = 1.74–4.92, P = 0.006), and extrapulmonary TB (AOR = 14.69, 95% CI = 8.21–26.26, P < 0.001). Generally, patients' delay in seeking care at health facilities was high (53.4%). Most of TB patients getting treatment from holy water (95.3%; 101/106) and traditional healers (84.6%; 11/13) were delayed. Therefore, for early seeking in modern health care, a combination of interventions is required to encourage TB patients.
Accommodation Tool Reference Point
Authors:   Truck and Bus Human Factors Committee
Published: March 2017

Reference lines have been developed to which driver workspace accomodation tools can be located in vehicle space. The lines describe horizontal reference point locations as a function of vehicle H-point height (H30). One reference line has been established for use in vehicles with H-point heights (H30) and steering wheel diameters (W9) less than 405 and 450 mm, respectively. (Class A Vehicles) This point can be used to reference appropriate workspace tools to accommodate a driver population with a male-to-female ratio of one-to-one. Separate reference lines have been established for use in vehicles with H-point heights (H30) between 405 and 530 mm and steering wheel diameters (W9) between 450 and 560 mm with treadle type pedals. (Class B Vehicles) See Figure 1. Three lines are available for use in Class B vehicles depending on the percentages of males and females in the population the designer wishes to accommodate. Separate points can be used to reference appropriate workspace tools to accommodate driver populations with male-to-female ratios of 50:50, 75:25, and 90:10 to 95:5. Different procedures for locating Class A and Class B accommodation tool reference lines in vehicle space have been established based on unique packaging considerations of the two categories of vehicles.

Energy Transfer System for Electric Vehicles--Part 1: Functional Requirements and System Architectures
Authors:   Electric Vehicle Forum Committee
Published: March 2017

SAE J2293 establishes requirements for Electric Vehicles (EV) and the off- board Electric Vehicle Supply Equipment (EVSE) used to transfer electrical energy to an EV from an Electric Utility Power System (Utility) in North America. This document defines, either directly or by reference, all characteristics of the total EV Energy Transfer System (EV-ETS) necessary to insure the functional interoperability of an EV and EVSE of the same physical system architecture. The ETS, regardless of architecture, is responsible for the conversion of AC electrical energy into DC electrical energy that can be used to charge the Storage Battery of an EV, as shown.
Energy Transfer System for Electric Vehicles - Part 2: Communication Requirements and Network Architecture
Authors:   Hybrid - EV Committee
Published: March 2017

SAE J2293 establishes requirements for Electric Vehicles (EV)
and the off-board Electric Vehicle Supply Equipment (EVSE) used to
transfer electric energy to an EV from an electric utility power
system (utility) in North America. This document defines, either
directly or by reference, all characteristics of the total EV
energy transfer system (EV-ETS) necessary to insure the functional
interoperability of an EV and EVSE of the same physical system
architecture. The ETS, regardless of architecture, is responsible
for the conversion of AC electrical energy into DC electrical
energy that can be used to change the storage battery of an EV, as
shown.

The different physical ETS system architectures are identified
by the form of the energy that is transferred between the EV and
the EVSE, as shown. It is possible for an EV and EVSE to support
more than one architecture.

This document does not contain all requirements related to EV
energy transfer, as there are many aspects of an EV and EVSE that
do not affect their interoperability. Specifically, this document
does not deal with the characteristics of the interface between the
EVSE and the utility, except to acknowledge the utility as the
source of energy to be transferred to the EV.

The functional requirements for the ETS are described using a
functional decomposition method. This is where requirements are
successively broken down into simpler requirements and the
relationships between requirements are captured in a graphic form.
The requirements are written as the transformation of inputs into
outputs, resulting in a model of the total system.

Each lowest level requirement is then allocated to one of four
functional groups (FG) shown. These groups illustrate the
variations of the three different system architectures, as the
functions they represent will be accomplished either on an EV or
within the EVSE, depending on the architecture. Physical
requirements for the channels used to transfer the power and
communicate information between the EV and the EVSE are then
defined as a function of architecture.

The requirements model in Section 6 is not intended to dictate a
specific design or physical implementation, but rather to provide a
functional description of the system's expected operational
results. These results can be compared against the operation of any
specific design. Validation against this document is only
appropriate at the physical boundary between the EVSE and EV
Need of standardization of herbal medicines in Modern era

Published: March 2017

The medicinal plants are important source for pharmaceutical manufacturing. Medicinal plants & herbal medicines account for a significant percentage of the pharmaceutical market. As the side effects of Synthetic medicine have started getting more apparent, majority of formulation are prepared from herbs. The herbal medicines however, suffer from lack of standardization parameters. The main limitation is the lack of standardization of raw materials, of processing methods and of the final products, dosage formulation, and the non existence of criteria for quality control. It is necessary to introduce measures on the regulation of herbal medicines to ensure quality, safety, efficacy of herbal medicines by using modern techniques, applying suitable standards & GMP.

Medicinal plants confer protective effects against a wide range of cancers including colon cancer. Cichorium endivia L. has many biological activities and functions, such as anti-inflammation and hepatoprotective effects. This activity is mainly due to its high levels of antioxidant compounds. The effect of cichorium extract and fluorouracil (5-FU) against colorectal cancer (CRC) induced by 1, 2- Dimethyl hydrazine (DMH) was examined in male albino mice. Where, different doses of cichorium extract (200, 400 and 600 mg/kg body weight) were investigated to determine the significant effective dose against colorectal cancer using differential display-PCR (DD-PCR), DNA sequencing, histopathological and cytological techniques. The results showed that the cichorium extract dose 200 mg/kg body weight was the best one compared to the others (400 and 600 mg/kg body weight). This finding could be a powerful therapeutic against colorectal cancer.

Abstract. Strict emission controls were implemented in Beijing and adjacent provinces to ensure good air quality during the 2015 China Victory Day parade. Here, we conducted synchronous measurements of submicron aerosols (PM1) at ground level and 260 m on a meteorological tower by using a high-resolution aerosol mass spectrometer and an aerosol chemical speciation monitor, respectively, in Beijing from 22 August to 30 September. Our results showed that the average PM1 concentrations are 19.3 and 14.8 µg m−3 at ground level and 260 m, respectively, during the control period (20 August–3 September), which are 57 and 50 % lower than those after the control period (4–30 September). Organic aerosols (OAs) dominated PM1 during the control period at both ground level and 260 m (55 and 53 %, respectively), while their contribution showed substantial decreases (∼  40 %) associated with an increase in secondary inorganic aerosols (SIAs) after the parade, indicating a larger impact of emission controls on SIA than OA. Positive matrix factorization of OA further illustrated that primary OA (POA) showed similar decreases as secondary OA (SOA) at both ground level (40 % vs. 42 %) and 260 m (35 % vs. 36 %). However, we also observed significant changes in SOA composition at ground level. While the more oxidized SOA showed a large decrease by 75 %, the less oxidized SOA was comparable during (5.6 µg m−3) and after the control periods (6.5 µg m−3). Our results demonstrated that the changes in meteorological conditions and PM loadings have affected SOA formation mechanisms, and the photochemical production of fresh SOA was more important during the control period. By isolating the influences of meteorological conditions and footprint regions in polluted episodes, we found that regional emission controls on average reduced PM levels by 44–45 %, and the reductions were close among SIA, SOA and POA at 260 m, whereas primary species showed relatively more reductions (55–67 %) than secondary aerosol species (33–44 %) at ground level.

Abstract. Triple-wavelength polarization lidar measurements in Saharan dust layers were performed at Barbados (13.1° N, 59.6° W), 5000–8000 km west of the Saharan dust sources, in the framework of the Saharan Aerosol Long-range Transport and Aerosol–Cloud-Interaction Experiment (SALTRACE-1, June–July 2013, SALTRACE-2, February–March 2014, SALTRACE-3, June–July 2014). Three case studies are discussed. High quality was achieved by comparing the dust linear depolarization ratio profiles measured at 355, 532, and 1064 nm with respective dual-wavelength (355, 532 nm) depolarization ratio profiles measured with a reference lidar. A unique case of long-range transport dust over more than 12 000 km is presented. Saharan dust plumes crossing Barbados were measured with an airborne triple-wavelength polarization lidar over Arkansas in the midwestern United States 7 days later. Similar dust optical properties and depolarization features were observed over both sites indicating almost unchanged dust properties within this one week of travel from the Caribbean to the United States. The main results of the triple-wavelength polarization lidar observations in the Caribbean in the summer seasons of 2013 and 2014 are summarized. On averaged, the particle linear depolarization ratios for aged Saharan dust were found to be 0.249 ± 0.030 at 355 nm, 0.308 ± 0.022 at 532 nm, and 0.224 ± 0.021 at 1064 nm after approximately one week of transport over the tropical Atlantic. Based on published simulation studies we present an attempt to explain the spectral features of the depolarization ratio of irregularly shaped mineral dust particles, and conclude that most of the irregularly shaped coarse-mode dust particles (particles with diameters > 1 μm) have sizes around 1.5–2 μm. The SALTRACE results are also set into the context to the SAMUM-1 (Morocco, 2006) and SAMUM-2 (Cabo Verde, 2008) depolarization ratio studies. Again, only minor changes in the dust depolarization characteristics were observed on the way from the Saharan dust sources towards the Caribbean.
