Ποιότητα ζωής σε ασθενείς μετά από πνευμονική εμβολή
Authors: Καρδακάρη Όλγα
Published: November 2024

Eισαγωγή: Αποτελέσματα με επίκεντρο τον ασθενή, όπως η ποιότητα ζωής που σχετίζεται με την υγεία, διαμορφώνουν το πλαίσιο αξιολόγησης των παρεχόμενων υπηρεσιών υγείας καιαποτελούν μέτρα έκβασης σε κλινικές δοκιμές. Ωστόσο αφενός υπάρχουν περιορισμένα δεδομένα για την σχετιζόμενη με την υγεία, ποιότητα ζωής ασθενών μετά από επεισόδιο πνευμονικής εμβολής, αφετέρου η αξιολόγηση προέρχεται μέσω γενικών ερωτηματολογίων ποιότητας ζωής. Μεθοδολογία: Η στάθμιση και αξιολόγηση των ψυχομετρικών ιδιοτήτων της ελληνικής έκδοσης του, ειδικού για την πνευμονική εμβολή, ερωτηματολογίου PEmb-QoL πραγματοποιήθηκε σε δείγμα 141 ασθενών 3 μήνες μετά από επεισόδιο πνευμονικής εμβολής, ενώ η μελέτη της μεταβολής της σχετιζόμενης με την υγεία, ποιότητας ζωής μέσω ειδικών και μη ειδικών ερωτηματολογίων πραγματοποιήθηκε σε δείγμα 150 ασθενών κατάτην οξεία φάση και στους 1, 3 και 12 μήνες μετά την έξοδο από το νοσοκομείο. Σε ένα υπό-σύνολο 54 ασθενών από την διαχρονική μελέτη, εξετάστηκε η συσχέτιση βασικών κλινικών, υπερηχογραφικών και βιοχημικών παραμέτρων κατά την οξεία φάση με τη δοκιμασία 6λεπτης βάδισης 12 μήνες μετά τη διάγνωση της ΠΕ. Αποτελέσματα: Η ελληνική έκδοση του PEmb-QoL εμφάνισε υψηλή εσωτερική συνέπεια, υψηλή συσχέτιση μεταξύ των στοιχείων και του συνόλου των στοιχείων και υψηλή αξιοπιστία δοκιμής-επανεξέτασης. Η μέση διαφορά στον πληθυσμό μεταξύ οξείας φάσης και 12 μηνών ήταν [-32.1 (95%CI: -34.6; -29.7), p<0.001] για το PEmb-QoL και [21.0 (95%CI:19.0-22.9), p<0.001] και [9.6(95% CI, 7.7-11.5), p<0.001] για τη φυσική και ψυχική διάσταση της γενικής υγείας, ωστόσο η πορεία της βελτίωσης ήταν μη γραμμική. Το φύλο, η ηλικία, ο δείκτης μάζας σώματος, η ύπαρξη ενεργού κακοήθειας και η ύπαρξη καρδιοαναπνευστικής νόσου κατά το επεισόδιο, είχαν συστηματική επίδραση στην πορεία της σχετιζόμενης με την υγεία, ποιότητας ζωής. Η εξάλεπτη δοκιμασία βάδισης συσχετίστηκεμε την ηλικία (r=-0.70, p<0.001), το eGFR (r=0.46, p<0.001), το δείκτη CCI (r=-0.50,p<0.001) και τα επίπεδα BNP κατά το επεισόδιο (r=-0.32, p=0.019). Συμπεράσματα: Η ελληνική έκδοση του PEmb-QoL έχει υψηλή αξιοπιστία και επαναληψιμότητα και κατά συνέπεια μπορεί να χρησιμοποιηθεί στον ελληνικό πληθυσμό. Η ειδική και γενική ποιότητα ζωής παρουσιάζουν στατιστικά σημαντική βελτίωση τους 3 πρώτους μήνες μετά από επεισόδιο ΠΕ, ενώ οι νεότεροι σε ηλικία ασθενείς έχουν πιθανότατατην καλύτερη έκβαση. Τα στατιστικά μοντέλα μπορούν να συνδράμουν στην αξιολόγηση της πορείας της ποιότητας ζωής σε ατομικό επίπεδο μέχρι και 12 μήνες μετά από επεισόδιο ΠΕ.

Αυτή η διατριβή μελετά την κλιματική αλλαγή και τον αντίκτυπό της στη βιώσιμη ανάπτυξη στην Αφρική. Το πρώτο μου δοκίμιο αφορά τον αντίκτυπο της ξηρασίας στα εκπαιδευτικά και υγειονομικά αποτελέσματα των παιδιών. Συντάσσω ένα παλινδρομικό σύνολο δεδομένων για παιδιά στην Αιθιοπία και μηνιαία δεδομένα βροχόπτωσης, για να διαπιστώσω ότι οι ξηρασίες μειώνουν την πιθανότητα εγγραφής των παιδιών στο σχολείο και επηρεάζουν αρνητικά την ολοκλήρωση των τάξεων. Τα αποτελέσματα δείχνουν επίσης ότι οι ξηρασίες αυξάνουν την καθυστέρηση ανάπτυξης και την αδυναμία στα παιδιά, ενώ επιδεινώνουν την επισιτιστική ανασφάλεια των νοικοκυριών. Το δεύτερο δοκίμιό μου αναλύει τους παράγοντες που καθορίζουν πότε οι αγρότες στην Αιθιοπία υιοθετούν Βιώσιμες Γεωργικές Πρακτικές (ΒΓΠ), όπως η εναλλαγή καλλιεργειών και η μικτή καλλιέργεια. Διαπιστώνω ότι η λήψη γεωργικής βοήθειας ενθαρρύνει τους αγρότες να υιοθετήσουν την εναλλαγή καλλιεργειών και ότι και οι δύο πρακτικές έχουν ισχυρό αντίκτυπο στη μείωση της επισιτιστικής ανασφάλειας στα νοικοκυριά. Στο τρίτο δοκίμιό μου, χρησιμοποιώ τεχνικές μηχανικής μάθησης (ML) για την πρόβλεψη της επισιτιστικής ανασφάλειας σε τέσσερις χώρες της Αφρικής. Δεδομένου ότι η επισιτιστική ανασφάλεια προκύπτει από σύνθετες αλληλεπιδράσεις μεταξύ οικονομικών σοκ, κλιματικής αλλαγής και περιφερειακών συγκρούσεων, συντάσσω δεδομένα υψηλής συχνότητας για αυτούς τους δείκτες. Υπολογίζω δύο ευρέως χρησιμοποιούμενα μοντέλα μηχανικής μάθησης, το Random Forest (RF) και το Extreme Gradient Boosting (XGBoost), για την πρόβλεψη της επισιτιστικής ανασφάλειας σε επίπεδο περιοχής. Διαπιστώνω ότι οι πιο σημαντικοί παράγοντες στην πρόβλεψη της επισιτιστικής ανασφάλειας είναι οι τιμές των τροφίμων και οι δείκτες βλάστησης. Συνολικά, διαπιστώνω ότι τα κλιματικά σοκ, τα οποία συμβαίνουν με υψηλή συχνότητα και ένταση, έχουν επιζήμιες επιπτώσεις στην εκπαίδευση, την υγεία και τη συνολική ευημερία των παιδιών. Η βιώσιμη γεωργία θα βοηθήσει τους αγρότες να αντιμετωπίσουν καλύτερα τα κλιματικά σοκ και να ανακουφίσουν την επισιτιστική ανασφάλεια στην ήπειρο.
Ο ρόλος των ΝΚ κυττάρων στην οξεία μυελογενή λευχαιμία
Authors: Χριστοδούλου Ηλίας
Published: November 2024

Η οξεία μυελογενής λευχαιμία (ΟΜΛ) είναι μια νόσος με πτωχή επιβίωση, ιδίως για τους ασθενείς με υποτροπιάζουσα ή ανθεκτική νόσο, παρά τις προόδους στη χημειοθεραπεία και τη μεταμόσχευση αιμοποιητικών βλαστικών κυττάρων. Οι τρέχουσες θεραπείες συχνά συνδέονται με σοβαρές τοξικότητες και περιορισμένη μακροχρόνια επιτυχία. Καινοτόμες κυτταρικές ανοσοθεραπείες, ιδίως αυτές που χρησιμοποιούν φυσικά φονικά (NK) κύτταρα, υπόσχονται τη βελτίωση των θεραπευτικών αποτελεσμάτων. Τα NK κύτταρα διαθέτουν εγγενείς αντι-λευχαιμικές ιδιότητες και μπορούν να τροποποιηθούν για να εκφράζουν χιμαιρικούς αντιγονικούς υποδοχείς (CARs), ενισχύοντας την αποτελεσματικότητά τους κατά της ΟΜΛ. Στην έρευνά μας, επικεντρωθήκαμε στη βελτίωση της δραστηριότητας κατά της ΟΜΛ και της επιβίωσης των NK κυττάρων με την γενετική τροποποίησή τους ώστε να εκφράζουν CARs που στοχεύουν το επιφανειακό αντιγόνο CD123 της ΟΜΛ, μαζί με την ιντερλευκίνη (IL)-15 για την αύξηση της επιβίωσης τους. In vitro και in vivo πειράματα έδειξαν ότι τα NK κύτταρα που εκφράζουν 2B4.ζ ή 4-1BB.ζ CARs έδειξαν καλύτερη αντικαρκινική δραστικότητα. Συγκεκριμένα, τα 2B4.ζ CAR-NK κύτταρα παρουσίασαν καλύτερη in vivo αποτελεσματικότητα σε σύγκριση με τα μη τροποποιημένα (UTD) και τα 4-1BB.ζ CAR-NK κύτταρα, αν και αυτό το όφελος ήταν προσωρινό λόγω περιορισμένης επιβίωσης των κυττάρων. Για να αντιμετωπίσουμε αυτό το πρόβλημα, εκφράσαμε την IL-15 (sIL-15) στα 2B4.ζ CAR και UTD NK κύτταρα, βελτιώνοντας την εκτελεστική λειτουργία και διατηρώντας ένα ενεργοποιημένο φαινότυπο των NK κυττάρων κατά τη διάρκεια χρόνιας διέγερσης με ΟΜΛ. Η αλληλούχιση RNA υποστήριξε αυτά τα ευρήματα, αναδεικνύοντας ένα ενεργοποιημένο μεταγραφικό τοπίο σε αυτούς τους τροποποιημένους πληθυσμούς NK κυττάρων. Ενώ τα 2B4.ζ/sIL-15 CAR-NK κύτταρα έδειξαν ισχυρή αντι-λευχαιμική δραστηριότητα σε ποντίκια, προκάλεσαν ταυτόχρονα σοβαρή τοξικότητα, υπογραμμίζοντας την ανάγκη για συστήματα ελέγξιμης έκφρασης κυτοκινών. Η έρευνά μας ανοίγει το δρόμο για την περαιτέρω ανάπτυξη ασφαλών θεραπειών με CAR-NK κύτταρα, με στόχο τη μεγιστοποίηση του θεραπευτικού οφέλους και την ελαχιστοποίηση των ανεπιθύμητων ενεργειών, προετοιμάζοντας το έδαφος για μελλοντικές κλινικές δοκιμές.

A new generalization of Lucas quaternions with finite operators
Authors: Özimamoğlu Hayrullah
Published: November 2024

In this paper, we introduce a new family of Lucas quaternions by using finite operators. We call these quaternions as Lucas finite operator quaternions. We give some properties and identities of Lucas finite operator quaternions such as Binet-like formula, generating function, exponential generating function, Catalan's identity, Cassini's identity, d'Ocagne's identity and many binomial-sum identities. As an application, we generate Cassini's identity in another form by matrix representations.
On the construction of iterated collocation-type approximations for linear fractional differential equations
Authors: Määrits Erik-Jürgen , Pedas Arvet , Vikerpuur Mikk
Published: November 2024

The present paper is concerned with the numerical solution of initial value problems for linear Caputo-type fractional differential equations. Some regularity results are presented and, using a reformulated integral equation approach, a high-order collocation method and its iterated version are constructed. Global superconvergence results of the iterated version are studied. Numerical examples confirming the theoretical results are also given.
Autorstwo. Urynkowienie literatury i fantazmat podmiotu autorskiego
Authors: Kobus Aldona
Published: November 2024

Zachodzące przemiany społeczno-kulturowe domagają się rewaloryzacji dotychczasowych ustaleń z zakresu prawa autorskiego i denaturalizacji pojęcia autorstwa, jego dyskursywizacji z uwzględnieniem kontekstów prawnych, ekonomicznych, estetycznych i teoretycznoliterackich. Autor jest nie tylko podmiotem procesu twórczego, lecz także nośnikiem określonej ideologii. Autorstwo wyłania się w XVIII wieku jako narzędzie w starciu sił politycznych, społecznych i ekonomicznych, autor staje się chwytem retorycznym w nierównej walce toczonej przez feudalny porządek z kapitalizmem. Opowieść o autorstwie to historia urynkowienia literatury i kultury. Ideologia autorstwa, maskowana wieloma metaforami i kategoriami (takimi jak oryginalność czy geniusz), podtrzymywana przez instytucje w rodzaju krytyki i teorii literatury, służy przemianie twórczości w przedmioty estetyczne, łatwe do skonsumowania towary bez kłopotów funkcjonujące na komercyjnym rynku. Jednocześnie zagadnienie autorstwa pozostaje problemem kulturowej autoidentyfikacji, określając, czyje głosy uchodzą za prawomocne i autorytatywne, a które podlegają systemowemu uciszaniu. Monografia stanowi kompleksowe omówienie historii autorstwa i jego licznych kontekstów: niekwestionowanej i niebezpiecznie anachronicznej dominacji romantycznego modelu autorstwa, represji autorstwa kobiecego, metaforycznej śmierci autora i problemu autorstwa zbiorowego.

Authors: Prarat Maciej
Published: November 2024

The publication is undoubtedly of a pioneering and innovative character. Various materials relating to a characteristic group of industrial buildings (but also older buildings) from the broadly understood Pomerania region created in the 19th century have been collected and analyzed, which has not been reported in the scientific literature on this subject so far. This comprehensive approach places the reviewed work among the basic publications necessary to recognize the selected issue.

Fragment of a review

Old mills, especially windmills, but also watermills, have already been the subject of numerous studies taking into account knowledge from field research and a certain amount of information from old literature on the subject. Meanwhile, the reviewed monumental treatise synthesized a huge amount of resources from numerous sources and old publications, which gave the work a character of a work organizing and summarizing all knowledge about ancient milling.

Teoretyczne podstawy badania stabilności politycznej
Authors: Perlikowski Łukasz
Published: November 2024

Książka Teoretyczne podstawy badania stabilności politycznej powstała z potrzeby odsłonięcia znaczeń kryjących się za twierdzeniami dotyczącymi stabilności politycznej. Co dokładnie mamy na myśli, gdy mówimy o stabilnym systemie politycznym? Czy stabilność to wartość uniwersalna? Czy stabilny rząd z konieczności prowadzi do stabilności systemu politycznego? Czy bardziej stabilny jest ustrój, który nie podlega żadnym zmianom, czy może taki, który odznacza się wyraźną dynamiką zmian? Czy brak zakłóceń działania systemu politycznego jest zawsze wynikiem stabilności politycznej, czy może występować pomimo niestabilności i słabości systemu? Podstawowym celem książki jest pomoc w zrozumieniu skomplikowanej tematyki stabilności politycznej i w osiągnięciu precyzji w posługiwaniu się poszczególnymi kategoriami. Dla Czytelnika szczególnie wartościowe mogą okazać się partie dotyczące metodologii analizowania stabilności pod kątem konfiguracji podmiotowych i przedmiotowych elementów systemu. Oprócz wątku formalno-metodologicznego w książce uwzględniono również wniosek substancjalny, związany z obserwacją tzw. paradoksu stabilności, który należy uznać za najważniejsze osiągnięcie badania naukowego, najmocniej wychodzące naprzeciw powszechnym intuicjom.

Teoretyczne podstawy badania stabilności politycznej  [Theoretical Foundations for the Study of Political Stability] was written out of the need to reveal the meanings behind claims about political stability. What exactly do we mean when we talk about a stable political system? Is stability a universal value? Does a stable government necessarily lead to a stable political system? Is a system that is not subject to any changes more stable, or perhaps one that is characterized by a clear dynamics of change? Is the lack of disruption in the functioning of the political system always the result of political stability, or can it occur despite the instability and weakness of the system? The primary goal of the book is to help understand the complex topic of political stability and achieve precision in using individual categories. The sections on the methodology of analyzing stability in terms of the configuration of subjective and objective elements of the system may be particularly valuable to the reader. In addition to the formal and methodological thread, the book also includes a substantive conclusion related to the observation of the so-called paradox of stability, which should be considered the most important achievement of scientific research, as it responds to common intuitions.
Miasto w ruchu. Studium z dziejów przemieszczania na przykładzie społeczeństwa Torunia 1891–1939
Authors: Bugowski Radosław
Published: November 2024

Kiedy życie miejskie zaczęło tętnić dłużej i głośniej? Kiedy piesi utracili pierwszeństwo w ruchu drogowym, a dorożki konne zostały wyparte przez samochodowe taksówki? Co spowodowało, że na początku XX wieku urzędnik miejski podróżował ponaddwukrotnie szybciej od robotnika?

Wraz z powstaniem i rozwojem silnika spalinowego oraz elektrycznego pojawiła się komunikacja miejska, powozy konne były zastępowane przez samochody, mieszkańcy korzystali z rowerów i motocykli. Zmieniły się warunki podróżowania w przestrzeni miejskiej. Jednak przemiany te nie były dostępne w równym stopniu wszystkim grupom społecznym. Możliwości szybszego i nowoczesnego przemieszczania stały się nowym przejawem rozwarstwienia społecznego.

Książka ta prezentuje proces zmian, jakie zaszły w sposobach podróżowania w przestrzeni miejskiej Torunia w latach 1891–1939. Autor podejmuje próbę udzielenia odpowiedzi na pytania: jak zmieniały się prędkość i jakość przemieszczania się w mieście, jak kształtowały się ruch uliczny i jego natężenie oraz jak przebiegał proces organizacji i prawnej regulacji ruchu. Znajomość tych zagadnień pozwala spojrzeć na miasto w szerszej perspektywie, pokazując wpływ procesów modernizacyjnych na funkcjonowanie społeczności miejskiej.
Świat po omacku. Etnograficzne studium (nie)widzenia i (nie)sprawności
Authors: Pietrowiak Kamil
Published: November 2024

Książka stanowi wielostronny opis życia osób niewidomych, w tym w szczególności niewidzących od urodzenia lub wczesnego dzieciństwa. Autor przybliża specyficzne doświadczenia, możliwości i ograniczenia przedstawicieli tej grupy, a także ogólniejsze kulturowe i społeczne uwarunkowania ich życia.

Celem książki jest odpowiedzenie na następujące pytania: Jak osoby niewidzące od urodzenia uczą się przypisanej im roli „nienormalnych” i „niepełnosprawnych”? Jaki wpływ na życie uczestników badań miał długoletni pobyt w specjalnych ośrodkach szkolno-wychowawczych? Jak osoby, które nie znają lub nie pamiętają wrażeń wzrokowych, odnajdują się w ramach ogólnie pojętej kultury wizualnej? W jakim stopniu i jakimi sposobami dostosowują się do norm i nakazów dotyczących dziedziny wyglądu? Jak radzą sobie z praktycznymi ograniczeniami, które wynikają bezpośrednio z braku zmysłu wzroku?

Podstawą prezentowanych rozważań są badania etnograficzne wśród osób niewidomych prowadzone w latach 2011‒2017. Ich zasadniczymi uczestnikami były 22 osoby niewidzące w wieku 18‒42 lat. W tym okresie autor nawiązał również liczne kontakty z innymi osobami niewidomymi, ociemniałymi i niedowidzącymi, ich znajomi i członkami rodzin, a także pracownikami instytucji i organizacji działających na rzecz tej grupy.

Badania stanowią również próbę realizacji i weryfikacji założeń etnografii opartej na współpracy (collaborative ethnography). Jednym z wyrazów pogłębionej współpracy z uczestnikami badań są ich komentarze dotyczące poszczególnych rozdziałów książki, które zostały zamieszczone na końcu każdej części.
Aporia wolności. Krytyka teorii społecznej
Authors: Kaczmarczyk Michał Roch
Published: November 2024

Wolność należy do najbardziej intrygujących pojęć – często uznawana za istotę człowieczeństwa lub podstawę porządku społecznego jest jednocześnie wypierana ze słownika socjologicznego jako anachronizm, na który nie ma miejsca w naukach społecznych. Odniesienia do wolności są pełne wieloznaczności i ambiwalencji skrywających zarówno problemy teoretyczne, jak i osobiste rozterki uczonych. Prezentowana książka zrywa z cichą tradycją unikania tematu wolności w naukach społecznych lub formułowania go w sposób, który odbiera mu jego zasadniczą wagę. W przekonaniu autora wyartykułowanie pierwszorzędnej roli, jaką problem wolności naprawdę odgrywa w socjologii, pozwala rzucić nowe światło na społeczno-polityczną rolę tej nauki, istniejące w niej podziały teoretyczne oraz jej przyszłe wyzwania. Książka dowodzi, że stosunek do wolności ma zasadnicze znaczenie dla każdej teorii społecznej. Tezę tę wspiera obszerny przegląd poglądów, które odcisnęły trwałe piętno na dziejach myśli społecznej w ciągu ostatnich dwóch stuleci. Czytelnik znajdzie w książce między innymi omówienie myśli takich klasyków teorii społecznej, jak Pierre Bourdieu, Cornelius Castoriadis, Émile Durkheim, Erving Goffman, Niklas Luhmann, Karol Marks, George Herbert Mead, Talcott Parsons czy Max Weber. Autor w nowy sposób ukazuje też strukturę wzajemnych relacji między głównymi nurtami refleksji socjologicznej – niewidoczną, gdy abstrahuje się od problematyki wolności. Osoby ceniące ideę wolności znajdą w prezentowanej książce nie tylko liczne uzasadnienia poglądu, że wolność jest wartością istotną dla porządku społecznego, lecz także analizę praktycznych i teoretycznych konsekwencji tego stanowiska.
Przeczucie końca. Modernizm, późność i polskie kino
Authors: Stelmach Miłosz
Published: November 2024

„Żaden człowiek nie jest samotną wyspą; każdy stanowi ułomek kontynentu, część lądu” – głosi słynna fraza Johna Donne’a, która posłużyła Ernestowi Hemingwayowi za motto powieści Komu bije dzwon. Parafrazując, można powiedzieć, że tym bardziej żadna kinematografia narodowa nie jest samotną wyspą; każda stanowi ułomek kontynentu, część lądu, jakim jest światowe kino i jeszcze szerzej – sztuka i kultura, przynajmniej od XIX wieku połączona siecią złożonych współzależności, inspiracji, uwarunkowań i powiązań o zasięgu globalnym. Powiązania te mogą mieć charakter ekonomiczny, intelektualny, polityczny, społeczny, artystyczny. Przeważnie są mieszanką ich wszystkich.

Dotyczy to także polskiego kina, a celem książki Przeczucie końca. Modernizm, późność i polskie kino jest przyjrzenie się wycinkowi rodzimej kinematografii, jaki stanowi powojenne kino autorskie, właśnie jako części tego bogatego kontynentu, którego jednym z najistotniejszych wymiarów był filmowy modernizm. Tropi ona kształtowanie się modernistycznego dyskursu, instytucji i poetyki zarówno w międzynarodowym, jak i lokalnym kontekście, a także kolejne przejawy i konsekwencje estetyczne oraz filozoficzne funkcjonowania tego paradygmatu w polskim kinie. Szczególny nacisk położony został na późną fazę modernizmu, której istnienie datuje się na lata siedemdziesiąte oraz (w mniejszym natężeniu) dekadę następną, a której czołowymi reprezentantami byli m.in. Andrzej Żuławski, Tadeusz Konwicki, Wojciech Jerzy Has, Grzegorz Królikiewicz czy Piotr Szulkin. Tego rodzaju „utransnarodowienie” polskiego kina pozwala spojrzeć na nie świeżym okiem, nawet jeśli przedmiotem jego zainteresowania są postaci, zjawiska czy dzieła pozornie dobrze znane.

Production Planning Under Demand and Endogenous Supply Uncertainty
Authors: Hewitt Mike , Pantuso Giovanni
Published: November 2024

We study the problem of determining how much finished goods inventory to source from different capacitated facilities in order to maximize profits resulting from sales of such inventory. We consider a problem wherein there is uncertainty in demand for finished goods inventory and production yields at facilities. Further, we consider that uncertainty in production yields is endogenous, as it depends on both the facilities where a product is produced and the volumes produced at those facilities. We model the problem as a two stage stochastic program and propose an exact, Benders-based algorithm for solving instances of the problem. We prove the correctness of the algorithm and with an extensive computational study demonstrate that it outperforms known benchmarks. Finally, we establish the value in modeling uncertainty in both demands and production yields.

Published: November 2024

A COVID-19 afetou os hábitos das populações: trabalho, estudo, mobilidade e relações interpessoais, tornando mais evidente as diferenças sociais. De uma forma geral, os governos vêm tomando ações no intuito de combater a pandemia e mitigar a velocidade de contaminação. Todavia, em muitos casos, estas ações têm se demonstrado desconectadas com a população. Dentro deste contexto, este artigo tem por intuito demonstrar a visão dos habitantes de São Paulo e Medellín acerca da efetividade das ações conduzidas pelos governos municipais, a fim de identificar situações em comum e contrastes. Para tal, foi conduzido um estudo de casos múltiplos em que munícipes foram entrevistados. Em seguida, as entrevistas foram transcritas e analisadas. A visão da população impactada pela pandemia é importante para a avaliação de políticas públicas em andamento e para o planejamento das ações a serem tomadas, de forma a garantir a resiliência das cidades em relação à crise estabelecida.

INTRODUÇÃO: O leite humano é o padrão-ouro de alimentação de lactentes sendo ainda mais elementar para bebês prematuros. OBJETIVO: Analisar a associação entre perdas de leite humano doado e as características das doadoras. MÉTODOS: estudo do tipo caso-controle, quantitativo, realizado através da análise de 619 registros de doadoras de leite humano que foram atendidas em um Banco de Leite Humano. RESULTADOS: Observou-se 48,3 % das doadoras apresentaram algum tipo de perda, sendo a sujidade e Acidez Dornic maior que 8º os tipos de perdas mais frequentes. Verificou-se que as condições de moradia não apresentaram associação com a perda de leite humano, bem como com as variáveis das características socioeconômicas, obstétricas e puerperais. CONCLUSÃO: Observamos que não há significância na associação entre as variáveis expositivas e a variável de desfecho. Contudo, visto que, houve uma perda de quase metade do leite doado e que a demanda por parte dos recém-nascidos é elevada, nota-se uma necessidade de intervenção para dirimir os problemas.

Introduction: Obesity, diabetes mellitus, and systemic arterial hypertension constitute the main chronic non-communicable diseases associated with inadequate nutrition. To help patients achieve lifestyle changes, an important step is to identify behavioral profiles.  Aims: This study aimed to characterize the eating behavior of Brazilian adult patients with diabetes and hypertension and compare its domain scores between sex, age groups, and body mass index (BMI). Methods: The cross-sectional study assessed eating behavior domains in patients from the Diabetes and Hypertension Center of the Federal University of Pelotas using the Three-Factor Eating Questionnaire. It also compared behavioral patterns between different groups.  Results: A total of 97 volunteer patients were included, with the majority being elderly (60.82%) and female (61.86%). Cognitive Restraint had the highest score among the domains. Females scored higher in Emotional Eating (EE) than males (p<0.003). Adults had significantly higher scores in EE (p<0.001) and Uncontrolled Eating (UE) (p<0.010) domains compared to the elderly. Subjects with overweight scored high in EE (p=0.003) and UE (p=0.028) across the sample. Adults with overweight had a higher EE score (p=0.014), while adults with obesity had higher scores for both EE (p=0.036) and UE domains (p=0.041). Conclusion: Differences in domain scores based on sex, age group, and BMI were observed. Understanding the eating behavior of this population can be crucial for planning effective interventions to address diabetes and hypertension management.

Authors: Lee Jun Ho , Ko Jong Cheul
Published: November 2024

Effect of baking on the physicochemical properties including pH, moisture content, hardness, color, and spread factor was investigated using a model system of cookies incorporated with strawberry powder as a value-added food ingredient. Strawberry powder was incorporated into cookie dough at 4 levels (0, 2, 4, and 6% w/w) by replacing equivalent amount of wheat flour of the cookie dough. After aging and sheeting, cookies were baked at 170°C for 15 min in an oven. The baked cookies were cooled to room temperature for 1 hr and packed in airtight bags prior to all measurements. The pH of dough and hardness of cookies decreased significantly with increase in strawberry powder content (p<0.05). Moisture content of the dough was not significantly affected by strawberry powder but mean values tended to increase as the strawberry powder content increased. Lightness (L*-value) and yellowness (b*-value) significantly decreased as the strawberry powder content increased; on the other hand, redness (a*-value) increased significantly (p<0.05). Spread factor also increased significantly as the strawberry content increased in the formulation (p<0.05). Finally, correlation analysis indicated that level of strawberry powder incorporation was wellcorrelated with all the physicochemical properties studied. It is also noted that there was a significant positive correlation between the moisture content of dough and spread factor (p<0.05).

Lactobacillus sakei B2-16 producing high level of γ-amino butyric acid (GABA) was previously isolated from Korean traditional fermented food, Kimchi. L. sakei B2-16 converted 99.3% of mono sodium glutamate (MSG) to GABA in Lactobacilli MRS broth supplemented with 1% MSG. In order to enhance the production of GABA by L. sakei B2-16, growth parameters such as media components and concentrations of major components were evaluated. The maximum GABA concentration was obtained by a modified rice germ extract broth containing 4%(w/v) sucrose and 1%(w/v) yeast extract. L. sakei B2-16 converted 100% of MSG to GABA in modified rice germ extract broth supplemented with 7% MSG.

Published: November 2024

The main objective of this study was to establish optimum condition of wet-grinding process for manufacturing microparticulated seaweed calcium. Process parameters such as concentration of forming agent, rotor speed, bead size, feed rate, and grinding time were adapted during wet-grinding of seaweed calcium. The particle size range of the raw seaweed calcium was 10-20 μm. The calcium particles were reduced to under 1 μm as nano scale after grinding. Gum arabic was suitable for forming agent and 5%(w/v) concentration was the most effective in grinding efficiency. A wet-grinding process operated at 4,000 rpm rotor speed, 0,4 mm bead size, and 0.4 L/hr feeding rate, respectively, produced less than 600 mm(>>90%)-sized particles. In batch systems, 8 cycles of grinding showed higher efficiency, but 20 min of grinding time in continuous processing was more efficient to reduce particle size than the batch processing. Based on the result, the optimum conditions of the wet grinding process were established: operation time of 20 minutes, rotor speed of 4,000 rpm, bead size of 0.4 mm, feed rate of 40 mL/min and 30% mixing ration with water. The size of the resulting ultra fine calcium particles ranged between 40 and 660 mm.

Published: November 2024

Blood coagulation and aggregation of platelet are crucial events in the pathogenesis of various ischemic diseases. The substance which can prevent blood coagulation and platelet aggregation was extracted from wood ear mushroom (Auricularia auricular-judae) and its anticoagulation activity was investigated. The dried A. auricular-judae was extracted with 0.1 N NaOH and its supernatant was further extracted with methanol and ethanol followed by H2O. The resulting methanol soluble fraction showed significant antithrombotic activity in activated partial thromboplastin time, thrombin time, and prothrombin time assays with values of 100, 124, and 54 sec, respectively. This active substance was purified with DEAE-Sepharose CL6B and Sephacryl 400-HR and was found to be polysaccharide with the average molecular weight of over 150 kDa. This polysaccharide was xyloglucomannan of which the main component was mannose, and its anticoagulant activity was mostly mediated by inhibition of thrombin activity.

Lactic acid bacteria was isolated for the production of probiotic animal feed supplemented with garlic and its antimicrobial properties were investigated. A total of 112 strains of lactic acid bacteria which grew on the medium containing garlic extract were isolated from kimchi, jeotgal, and jangachi. Among them 14 strains were tested for acidand bile salt-resistance as well as antimicrobial activities against animal pathogenic bacteria such as Salmonella choleraesuis, Escherichia coli, Staphylococcus aureus, and Shigella flexneri. Of these strains, a strain P'GW50-2 from pickled scallion with most desirable properties was selected and identified as Lactobacillus plantarum TJ-LP-002. Antimicrobial activity of L. plantarum TJ-LP-002 showed relatively wide range of inhibition spectrum against Gram negative bacteria such as Aeromicrobium hydrophila, E. coli, Pseudomonas, Salmonella, Shigella, and some Gram positive bacteria such as Bacillus cereus, Staphylococcus aureus, Clostridium perfringens, and Propionibacterium.

Authors: Mok Chulkyoon , Song Dong-Myung
Published: November 2024

Low-pressure plasmas (LPPs) were generated with different gases such as air, oxygen and nitrogen, and their inactivation effects against Escherichia coli were compared in order to evaluate the potential as a non-thermal microbial disinfection technology. Homogeneous plasmas were generated under low pressure below 1 Torr at gas flow rate of 350 mL/min regardless the types of gases. Temperature increases by LPPs were not detrimental showing less than 10°C and 25°C increases after 5 and 10 min treatments, respectively. The smallest temperature increase was observed with air LPP, and followed by oxygen and nitrogen LPPs. More than 5 log reduction in E. coli was achieved by 5 min LPP treatment but the destruction effect was retarded afterward. The LPP inactivation was represented by a biphasic first order reaction kinetics. The highest inactivation rate constant was achieved in air LPP and followed by oxygen and nitrogen LPPs. The small D-values of the LPP also supported its potentialities as a non-thermal food surface disinfection technology in addition to the substantial microbial reduction of more than 5 logs.

Published: November 2024

This study was to investigate the combined effect of enzyme and trehalose addition on the retrogradation rate and quality changes in a Korean traditional rice cake, Backsulgi. As for the enzyme, a commercial maltogenic amylase, Novamyl, was used. From texture profile analysis and sensory tests, the optimum enzyme content for the preparation of Backsulgi was determined to be 0.1%. Backsulgi was prepared with the fixed content of Novamyl (0.1%) and different ratios (5, 10, 15%) of trehalose, and physicochemical and sensory properties were examined for 3 days of storage at 25°C. As trehalose content increased, the water activity of Backsulgi decreased. In Hunter's color value, L- and a-values of trehalose-added samples were significantly lower than those of control. In texture profile analysis, hardness of Backsulgi decreased with trehalose content. During storage, a increase in hardness and a decrease in cohesiveness were typically observed for all samples. However, those changes were significantly reduced with trehalose content. The retardation of retrogradation with the enzyme and trehalose addition was confirmed using calculated Avrami rate and time constants. These results revealed that combined treatments of 0.1% Novamyl and 10% trehalose could produce Backsulgi of better sensory quality with retarded retrogradation compared to separated treatment.

Published: November 2024

The optimum condition for the extraction and purification processes of phytic acid from defatted rice bran was examined. The phytic acid was efficiently extracted when the defatted rice bran was treated with 10 volumes of 0.5% HCl for 1 hr. For the neutralization of acid-treated extract, 0.5% NaOH was the most acceptable. To purify phytic acid, Diaion HP20 resin was used to remove impurities from the extract. The flow-through was then loaded onto ion exchange columns packed with various resins and among them, Amberlite IRA-416 resin showed highest recovery yield. When the phytic acid was absorbed onto Amberlite IRA-416 resin and then eluted with 0.5% NaOH, 89% of applied phytic acid was eluted. Most proteins were removed from the purified phytic acid and total protein content of the phytic acid was 0.14% (w/w).

In order to improve the sensory preference and to mitigate the bitter taste of green tea extract products, 100 microorganisms isolated from Korean traditional fermented foods were used to ferment green tea extract and the analysis of catechins and sensory evaluation of the fermented green tea extract products were undertaken. When the isolates were cultured into 2, 4, 6, 8, and 10% green tea extract, the highest growth rates were observed when 2 and 4% of green tea extract were used as growth medium. When the contents of catechin components of non-fermented and fermented green tea extracts were analyzed by HPLC, there was a significant decrease in content of epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin (EC) (EGCG: 125.45→65.42 μg/mg, EGC: 85.96→38.03 μg/ mg, EC: 25.64→13.84 μg/mg), whereas there was a significant increase in content of gallocatechin gallate (GCG) and gallocatechin (GC) (GCG: 7.79→85.22 μg/mg, GC: 9.46→64.59 μg/mg). Eleven strains of lactic acid bacteria, which showed relatively small content of gallate-type catechins (EGCG, ECG, GCG, CG) in their fermented green tea extracts, were selected and used for sensory test. As a result of sensory evaluation, Lactobacillus plantarum 62901 and Leuconostoc pseudomesenterioides K200132 showed the best score in overall preference. Their fermented products also showed strong roasted flavor while decreased grass flavor and bitter taste were observed.
