The municipal public transport microclimate in Chisinau during the warm season
Full text linkNicolae Testemitanu State University of
Medicine and Pharmacy, Chisinau, Republic of Moldova, The 6th International Medical Congress for Students and Young Doctors, May 12-14, 2016Basic. Municipal public transport has been and is very current. Daily, in Chisinau, the
transportation of 800 thousand passengers is made with the help of 280 electric cars and 200 cars with
internal combustion engine. In Republic of Moldova the conditions of work and the health of workers
in the field of public transport are insufficiently studied. The importance of the topic increases given that
many women are working in the field, therefore emphasizing the need for the study.
Materials and methods. We evaluated the microclimate parameters in the saloons of public
transport from Chisinau using the apparatus Meteoscop M. Basic indicators such as air temperature,
relative humidity and velocity of currents which was considered constant (0.1 m/s) were examined in
accordance with the rules. Three sets of measurements were performed in order to record the transition
from the cold season to the warm season which included 50 electric cars per day, and then the Sigma
method was used in order to analyze the statistical average of the measurements. The quality index of
the microclimate was evaluated, namely the Actual Temperature, Thermal load and the Wind Chill. Then
these results were compared with the regulatory framework in the given domain.
Discussion of the results. We compared the results of the Actual Temperature with European
regulatory framework nomograms in the field of occupational health and environmental health
(89/654/EEC and FRR 2.2.2006-05; RNI 2.2.4.548 -96) and we determined that the actual temperature
exceeded the maximum required in 2 cases. In April the index of actual temperature falls within the
normal range, and in May and June it exceeded the normal temperature of 29.1 ° C with 1.5 ° C, and
respectively, 7.2 ° C.
The conclusion. This fact speaks about very hot working conditions during the warm season of
the year, and as a result diseases of the cardiovascular system may occur
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Знания о вирусном гепатите B среди медицинских работников
Full text linkSummary
Healthcare workers are at an increased risk of hepatitis B
virus infection due to frequent contact with patients’ bodily
fl uids. Studies indicate that healthcare workers may experience between 1 and 3 needle stick or sharp object injuries
per year, each incident increasing the risk of infection with
blood-borne viruses, including hepatitis B. A sample of 318
primary healthcare workers was interviewed, including 87
doctors and 231 nurses. Th e collected data was analyzed
using EpiInfo 7.2 soft ware. Among the healthcare workers
who participated in this study, 276 (86.79%) had adequate
knowledge about HBV transmission routes, including 89.77%
of doctors and 85.72% of nurses. It is noteworthy that some
workers are unaware of HBV transmission routes, mentioning transmission through kissing – 60 people (18.87%, [95%
CI 14.80% - 23.58%]), through coughing and sneezing – 17
people (3.35%, [95% CI 3.14% - 8.41%]), by drinking from a
glass already used by an infected person – 34 people (10.69%,
[95% CI 7.54% - 14.56%]), while sharing meals – 14 people
(4.40%, [95% CI 2.44% - 7.27%]), through vegetables and
fruits – 10 people (3.14%, [95% CI 1.52% - 5.70%]). Th e
level of knowledge about the HBV transmission pathway
observed in this study is relatively adequate, but at the same
time, signifi cant gaps in knowledge about the risks of HBV
transmission were highlighted.Rezumat
Cunoștințele lucrătorilor medicali privind hepatita virală B
Lucrătorii medicali sunt expuși unui risc crescut de infectare
cu virusul hepatitic B (VHB), deoarece au contact frecvent cu
fl uidele corporale ale pacienților. Studiile indică faptul că anual
aceștia pot suferi între 1 și 3 accidente cu ace sau alte obiecte
ascuțite, fi ecare incident crescând riscul de infectare cu virusurile transmisibile prin sânge, inclusiv hepatita B. Într-un studiu
realizat în asistența primară, au fost intervievați 318 lucrători
medicali, inclusiv 87 de medici și 231 de asistente medicale. Datele colectate au fost analizate folosind programul EpiInfo 7.2. Din
totalul participanților, 276 (86,79%) aveau cunoștințe adecvate
despre calea de transmitere a VHB, prcetajul fi ind de 89,77%

infectată, 14 persoane (4,40% [95% IC 2,44%-7,27%] prin luarea
masei împreună și 10 persoane (3,14% [95% IC 1,52%-5,70%]) prin consumul de legume și fructe. Concluziile studiului indică
un nivel relativ adecvat al cunoștințelor privind calea de transmitere a HVB în rândul lucrătorilor medicali, dar subliniază
și necesitatea de a corecta lacunele semnifi cative identifi cate în
înțelegerea riscurlor asociate cu transmiterea HVB.Резюме
Знания о вирусном гепатите B среди медицинских
работников
Медицинские работники подвержены повышенному
риску заражения вирусом гепатита B из-за частого
контакта с биологическими жидкостями пациентов.
Исследования показывают, что медицинские работники могут сталкиваться с 1–3 случаями травмирования иглой или другими острыми предметами
в год, что увеличивает риск заражения кровяными
вирусами, включая гепатит B. Были опрошены 318
медицинских работников первичной медико-санитарной помощи, в том числе 87 врачей и 231 медсестра.
Собранные данные были проанализированы с использованием программы EpiInfo 7.2. Среди медицинского
персонала, участвовавшего в этом исследовании, 276
(86,79%) имели адекватные знания о путях передачи
HBV, включая 89,77% врачей и 85,72% медсестер. Стоит отметить, что некоторые работники не знают
о путях передачи гепатит B, упоминая передачу
через поцелуи – 60 человек (18,87%, [95% ДИ 14,80% -
23,58%]), через кашель и чихание – 17 человек (3,35%,
[95% ДИ 3,14% - 8,41%]), при питье из стакана, из
которого уже пил инфицированный человек – 34
человека (10,69%, [95% ДИ 7,54% - 14,56%]), при совместном приеме пищи – 14 человек (4,40% [95% ДИ
2,44% - 7,27%]), через овощи и фрукты – 10 человек
(3,14% [95% ДИ 1,52% - 5,70%]). Уровень знаний о
путях передачи гепатите B, отмеченный в данном
исследовании, является относительно адекватным,
но в то же время были выявлены значительные пробелы в знаниях о рисках передачи гепатите B
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
The Municipal Public Transport microclimate in Chișinău
Full text linkDepartment of General Hygiene,
Nicolae Testemitanu State University of Medicine and Pharmacy of the Republic of MoldovaIntroduction. At the moment, public transport in Chișinău has a very important role, especially
trolleybuses. Every day around 300 units are circulating in Chisinau carrying about 50 thousand
passengers.
Aim of the study. The problem of the working conditions of drivers and passengers in transport
is insufficiently studied.
Materials and methods. We measured the microclimate parameters in the trolleybuses from
Chișinău with the device Meteoscope M, basic indicators such as air temperature and relative
humidity, the current velocity being considered constant 0.1 m / s, according to the norms. Three
sets of measurements were performed in order to record the transition from autumn to winter
which included 40 electric cars per day, and then the Sigma method was used in order to analyze
the statistical average of the measurements The quality index of the microclimate was evaluated,
namely the Actual Temperature. Then these results were compared with the regulatory
framework in the given domain
Results. We compared the results of the Actual Temperature with European regulatory
framework nomograms in the field of occupational health and environmental health
(89/654/EEC and FRR 2.2.2006-05; RNI 2.2.4.548 -96) and we determined that the actualtemperature exceeded the minimum required in 2 cases. In October the index of actual
temperature falls within the normal range, and in December and February it doesn’t reach the
normal minimum 18 ° C.
Conclusions. This fact speaks about very cold working conditions during the cold season of the
year, and as a result one might experience different diseases of the respiratory, urinary or
cardiovascular system and many more. It is recommended that the worker wear warm clothing,
work breaks, the organization of a special diet
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
