Wskaźniki bibliometryczne w ocenie aktywności publikacyjnej pracowników naukowych
The assessment of the scientific potential of institutions can be made by using a variety of numerical indicators. In order to determine the scientific level of Polish institutions one should apply the indicators and methods used for assessing international learning. To this end, researchers frequently use comparisons of publishing activity, frequency of citation and bibliometric indicators aimed at illustrating more qualitative than quantitative status of science. The paper presents the most commonly used measures of publishing activity evaluation (the number of publications, the number of citations, the Impact Factor, the Hirsch Index). It also discusses the pros and cons of the Hirsch Index as a method of evaluation of scientific achievements of both individuals and institutions. In addition, the authors have made reference to a system based on the Impact Factor
Rola i zadania bibliotek instytutów badawczych
Currently, there are 115 research institutes in Poland which were called previously Research and Development units. Most of them have a scientific library in their structure that collects specialist sets of documents which often constitute a unique value for very narrow disciplines of science. These libraries serve the needs of science and education providing access to global information resources, as well as publications and research results generated at the parent research institute. Libraries also perform tasks related to the digitization of documents, they build digital collections, create institutional repositories, perform bibliometric analyzes and report on publishing output of institutes to central institutions.Obecnie w Polsce funkcjonuje 115 instytutów badawczych nazywanych wcześniej jednostkami badawczo-rozwojowymi. Większość z nich posiada w swojej strukturze bibliotekę naukową, która gromadzi specjalistyczne zbiory dokumentów, stanowiące często niepowtarzalną wartość dla bardzo wąskich dyscyplin nauki. Biblioteki te służą potrzebom nauki i edukacji, zapewniając dostęp do światowych zasobów informacyjnych oraz do publikacji i wyników badań powstających w macierzystym instytucie badawczym. Biblioteki wykonują też zadania związane z cyfryzacją dokumentów, budują kolekcje cyfrowe, tworzą repozytoria instytucjonalne, przeprowadzają analizy bibliometryczne oraz sprawozdają dorobek publikacyjny instytutów do instytucji centralnych
Bibliograficzne bazy danych dla bibliotekarzy, naukowców czy urzędników?
Znaczenie bibliograficznych baz danych dla rozwoju [otwartej] nauki można określić poprzez spojrzenie na sposoby korzystania z nich przez różne grupy odbiorców. Kto i w jakim celu użytkuje bibliograficzne bazy danych - bibliotekarze, naukowcy czy urzędnicy? Która z tych grup w istotny sposób wpływa na rozwój nauki? Gdzie tkwi potencjał do wykorzystania w bibliograficznych bazach danych? Referat będzie próbą odpowiedzi na te pytania w oparciu o przykłady zastosowań baz (w szczególności bazy MEDLINE) do eksploracji danych, metaanaliz i tworzenia przeglądów systematycznych
System Informacji o Nauce – zakres danych i informacji objętych systemem, terminy aktualizacji i sposób udostępniania danych
Scientific institutions that apply for the funds for statutory activity are obliged to enter relevant data to the tele-information system in a systematic way. The act on funding science and normative acts that regulate the System of Information on Science specify which data and where they need to be documented. The system also includes information on the point value of scientific publications, the authors of which come from Polish units as well as information on citations of articles from Polish scientific journals. The article presents the scope of data contained in the system, updates deadlines and the way of making them accessible.Jednostki naukowe, które ubiegają się o środki finansowe na działalność statutową, zobowiązane są do systematycznego wprowadzania odpowiednich danych do systemu teleinformatycznego. Jakie dane i gdzie mają być udokumentowane określa ustawa o finansowaniu nauki oraz akty normatywne regulujące System Informacji o Nauce. System obejmuje też informacje o wartości punktowej publikacji, których autorzy pochodzą z polskich instytucji oraz o cytowaniach artykułów z polskich czasopism naukowych. Artykuł przedstawia zakres danych objętych systemem, terminy aktualizacji i sposób ich udostępniania.
Article level metrics - wskaźniki popularności publikacji naukowych
The article presents new meters of popularity of scientific publications in the Internet – article level matrics (ALM), which are more and more frequently introduced by publishers and information suppliers. These meters indicate the number of citation of articles in databases (e.g. Web of Science, Scopus), in social media (e.g. Twitter, Facebook), programmes used for publications management (e.g Mendeley), blogs. They also count the number of views of the website of the article. New approach towards evaluation of individual scientific publications and rising importance of social services in assessment of science constitute an alternative to the so far used overall assessment of journals and granting them Impact Factor indicator

Polish statement on food allergy in children and adolescents
An adverse food reaction is defined as clinical symptoms occurring in children, adolescents or adults after ingestion of a food or chemical food additives. This reaction does not occur in healthy subjects. In certain individuals is
a manifestation of the body hypersensitivity, i.e. qualitatively altered response to the consumed food. The disease
symptoms observed after ingestion of the food can be triggered by two pathogenetic mechanisms; this allows
adverse food reactions to be divided into allergic and non-allergic food hypersensitivity (food intolerance). Food
allergy is defined as an abnormal immune response to ingested food (humoral, cellular or mixed). Non-immunological mechanisms (metabolic, pharmacological, microbiological or other) are responsible for clinical symptoms
after food ingestion which occur in non-allergic hypersensitivity (food intolerance).
Food allergy is considered a serious health problem in modern society. The prevalence of this disorder is varied
and depends, among other factors, on the study population, its age, dietary habits, ethnic differences, and the
degree of economic development of a given country. It is estimated that food allergy occurs most often among
the youngest children (about 6-8% in infancy); the prevalence is lower among adolescents (approximately 3-4%)
and adults (about 1-3%). The most common, age-dependent cause of hypersensitivity, expressed as sensitization or allergic disease (food
allergy), are food allergens (trophoallergens). These are glycoproteins of animal or plant origine contained in: cow's
milk, chicken egg, soybean, cereals, meat and fish, nuts, fruits, vegetables, molluscs, shellfish and other food products. Some of these allergens can cause cross-reactions, occurring as a result of concurrent hypersensitivity to food,
inhaled or contact allergens.
The development of an allergic process is a consequence of adverse health effects on the human body of different
factors: genetic, environmental and supportive. In people predisposed (genetically) to atopy or allergy, the development of food allergy is determined by four allergic-immunological mechanisms, which were classified and described
by Gell-Coombs. It is estimated that in approximately 48-50% of patients, allergic symptoms are caused only by
type I reaction, the IgEmediated (immediate) mechanism. In the remaining patients, symptoms of food hypersensitivity are the result of other pathogenetic mechanisms, non-IgE mediated (delayed, late) or mixed (IgE mediated,
non-IgE mediated). Clinical symptomatology of food allergy varies individually and depends on the type of food induced pathogenetic
mechanism responsible for their occurrence. They relate to the organ or system in which the allergic reaction has
occurred (the effector organ). Most commonly the symptoms involve many systems (gastrointestinal tract, skin,
respiratory system, other organs), and approximately 10% of patients have isolated symptoms. The time of symptoms onset after eating the causative food is varied and determined by the pathogenetic mechanism of the allergic immune reaction (immediate, delayed or late symptoms). In the youngest patients, the main cause of food reactions is allergy to cow’s milk. In developmental age, the clinical picture of food allergy can change, as reflected in the so-called allergic march, which is the result of anatomical and functional maturation of the effector organs, affected by various harmful allergens (ingested, inhaled, contact allergens and allergic cross-reactions). The diagnosis of food allergy is a complex, long-term and time-consuming process, involving analysis of the allergic history (personal and in the family), a thorough evaluation of clinical signs, as well as correctly planned allergic
and immune tests. The underlying cause of diagnostic difficulties in food allergy is the lack of a single universal laboratory test to identify both IgE-mediated and non-IgE mediated as well as mixed pathogenetic mechanisms of
allergic reactions triggered by harmful food allergens. In food allergy diagnostics is only possible to identify an
IgE-mediated allergic process (skin prick tests with food allergens, levels of specific IgE antibodies to food allergens). This allows one to confirm the diagnosis in patients whose symptoms are triggered in this pathogenetic
mechanism (about 50% of patients). The method allowing one to conclude on the presence or absence of food
hypersensitivity and its cause is a food challenge test (open, blinded, placebo-controlled). The occurrence of clinical symptoms after the administration of food allergen confirms the cause of food allergy (positive test) whereas
the time elapsing between the triggering dose ingestion and the occurrence of clinical symptoms indicate the pathogenetic mechanisms of food allergy (immediate, delayed, late). The mainstay of causal treatment is temporary removal of harmful food from the patient’s diet, with the introduction of substitute ingredients with the nutritional value equivalent to the eliminated food. The duration of dietary
treatment should be determined individually, and the measures of the effectiveness of the therapeutic elimination
diet should include the absence or relief of allergic symptoms as well as normal physical and psychomotor development of the treated child. A variant alternative for dietary treatment of food allergy is specific induction of food tolerance by intended contact of the patient with the native or thermally processed harmful allergen (oral immunotherapy). This method has
been used in the treatment of IgE-mediated allergy (to cow's milk protein, egg protein, peanut allergens).
The obtained effect of tolerance is usually temporary. In order to avoid unnecessary prolongation of treatment in a child treated with an elimination diet, it is recommended to perform a food challenge test at least once a year. This test allows one to assess the body's current ability to acquire immune or clinical tolerance. A negative result of the test makes it possible to return to a normal diet,
whereas a positive test is an indication for continued dietary treatment (persistent food allergy). Approximately 80% of children diagnosed with food allergy in infancy "grow out" of the disease before the age of
4-5 years. In children with non-IgE mediated food allergy the acquisition of food tolerance is faster and occurs in
a higher percentage of treated patients compared to children with IgE-mediated food allergy.
Pharmacological treatment is a necessary adjunct to dietary treatment in food allergy. It is used to control the rapidly increasing allergic symptoms (temporarily) or to achieve remission and to prevent relapses (long-term treatment).
Preventive measures (primary prevention of allergies) are recommended for children born in a "high risk" group for
the disease. These are comprehensive measures aimed at preventing sensitization of the body (an appropriate way
of feeding the child, avoiding exposure to some allergens and adverse environmental factors). First of all, the infants
should be breast-fed during the first 4-6 months of life, and solid foods (non milk products, including those containing gluten) should be introduced no earlier than 4 months of age, but no later than 6 months of age. An elimination diet is not recommended for pregnant women (prevention of intrauterine sensitization of the fetus and
unborn child). The merits of introducing an elimination diet in mothers of exclusively breast-fed infants, when the
child responds with allergic symptoms to the specific diet of the mother, are disputable. Secondary prevention focuses on preventing the recurrence of already diagnosed allergic disease; tertiary prevention is the fight against organ
disability resulting from the chronicity and recurrences of an allergic disease process. Food allergy can adversely affect the physical development and the psycho-emotional condition of a sick child, and
significantly interfere with his social contacts with peers. A long-term disease process, recurrence of clinical symptoms, and difficult course of elimination diet therapy are factors that impair the quality of life of a sick child and
his family. The economic costs generated by food allergies affect both the patient's family budget (in the household), and the overall financial resources allocated to health care (at the state level). The adverse socio-economic
effects of food allergy can be reduced by educational activities in the patient’s environment and dissemination of
knowledge about the disease in the society
Wokół zagadnień trwałej ochrony zasobów cyfrowych
Słowo wstępne: "Cyfrowe kolekcje wartościowych dokumentów powstają w wyniku procesów
elektronicznego publikowania oraz digitalizacji materiałów analogowych.
Są one świadectwem dorobku polskiej działalności naukowej i kulturowej.
Digitalizacja upowszechnia się w instytucjach pamięci jako forma zabezpieczenia
zagrożonych zniszczeniem oryginalnych materiałów. Oficyny wydawnicze
coraz częściej publikują treści naukowe w cyfrowej postaci, rezygnując
z wersji drukowanych. Instytuty naukowe i badawcze oraz uczelnie wyższe
tworzą instytucjonalne repozytoria, pozwalające na szybkie i samodzielne
udostępnianie publiczności wyników prowadzonych prac badawczych. Powstające
w ten sposób cyfrowe zasoby współtworzą światowe dziedzictwo.
Podlegają one trwałej ochronie z myślą o potrzebach obecnych i przyszłych
użytkowników."(...
Przenikanie wiedzy między ośrodkami badawczymi na przykładzie analizy bazy SCOPUS
The recent technological advances in communication and information systems, including the methods for data collection, storage and processing, have been a new challenge for library services. Obviously, nobody questions the meaning of the library itself but the traditional library services will have to give way to the new technologies and data sources. The latter make it possible to trace the information flow and analyze the scope and content of data sought. A recent trend has been that of multidisciplinary databases that contain publications regarding different fields of science. These databases make it possible to follow the quantitative relations between publications coming from different fields and countries of origin. The present paper discusses the results of analyzing the SCOPUS database search in one of the medical sciences, taking as an example the publications on occupational health from two professional journals: International Journal of Occupational Medicine and Environmental Health, edited in English, and Medycyna Pracy (Occupational Medicine), edited in Polish. The most frequent citations of these publications were analyzed to trace the transfer of medical knowledge between research centres worldwide
