Arhitektura - inkluzivna kultura - zaštita osoba sa invaliditetom
The paper has analyzed the contemporary standards that all democracies have embraced. A special emphasis has been placed on international conventions and rules, as well as the laws to protect the rights of all members of a modern social community. It is its duty to look after all its members and eliminate any form of discrimination, and even a threat of it. The European Concept for Accessibility promotes a new social model, designed to change entirely the attitude to the handicapped. The Concept offers a completely new approach, viewing the community as a whole. This integrated approach stretches to the needs of the community and the needs of each and every member of it, making no difference between individual groups within the population. Instead, it creates the environment to satisfy the needs of each individual member and, by extension, the community at large. The role of architecture is to recognize the needs of a community and take the lead in reshaping the standards to create a new environment accessible to all its members. This will give architecture a fundamental dimension, and make it the integrative factor to blend the community together.Rad je baziran na analizi savremenih standarda koji važe u demokratskim društvima. Posebno su analizirane međunarodne konvencije i pravila i analizirana je regulative koja se bavi zaštitom prava svih članova savremene društvene zajednice. Zadatak savremene društvene zajednice je da brine o svim članovima zajednice id a otkloni svaki, pa i potencijalni oblik diskriminacije. Primenom Evropskog koncepta pristupačnosti ostvarila bi se promocija novog socijalnog modela kojim bi se u potpunosti promenio odnos prema osobama sa inaliditetom. Koncept predviđa suštinski drugačiji pristup, društvenu zajednicu posmatra kao celinu, pa tako i i potrebe zajednice kao celine, a onda i svakog pojedinačnog člana i ne pravi razliku između pojedinih grupa u ukupnoj populaciji, nego rešenjima ispunjava uslove za zadovoljenje potreba svakog pojedinačnog člana, a time i zajednice u celini. Uloga arhitekture je da prepozna potrebe društvene zajednice i preuzme važnu ulogu u kreiranju standard za novo okruženje, koje će biti dostupno svim članovima zajednice. Time arhitektura dobija svoju suštinsku dimenziju i postaje integrativni faktor zajednice kao celine.

Јапанска Soft Power архитектура: (не)намерно и неочекивано у политици културне размене
States’ cultural policies for international relations take various
forms, both intangible and tangible. This paper will focus
on the latter, namely, exported architectural manifestation
utilized as cultural negotiation tools. In this research, exported
architecture is considered to be any built (realized) spatial
manifestations, non-native to the county in which it is placed.
Subsequently, architecture is viewed and examined as a cultural
resource, having the power to influence bilateral relations
presenting a new term, ‘soft power architecture’ as conceived,
exported, and state-controlled spatial manifestation, with a
clear set of goals inscribed within cultural relations policies.
The notion of architecture-as-a-negotiating-instrument
between various actors is introduced, borrowing from Joseph
S. Nye’s definition of the term “soft power” postulated as, in
the most basic terms, as the ability to attract, with attraction
often leading to acquiescence.These typologies have a
profound impact and yet the policy makers remain unaware
of the importance of architectural manifestations as cultural
resources. Requirements of the re-conceptualization of the
state’s policies regarding the planning, implementation and
management processes for diplomatic-consular outpost will be
discussed. Lastly, the case study of the new Japanese embassy
in Belgrade, Serbia, will be examined, noting particularities
of its processes, arguing an unintentional paradigmatic shift,
providing a theoretical and methodological framework for
future research.Међународни односи и пратеће стратегије културне размене
могу попримати различите облике, како нематеријалне, тако
и опипљиве. Овај рад ће се фокусирати на другу категорију,
наиме, извезене архитектонске манифестације које се могу
користити као оруђе у политици културне размене. У овом
истраживању, за извезену архитектуру сматра се било која
изграђена (реализована) просторна манифестација, која
потекла из окружења у којем је смештена. Архитектура ће
бити посматрана и испитивана као културни ресурс, који
има моћ утицаја на билатералне односе, представљајући
нови термин, „Soft Power архитектура“ који подразумева
пројектовану, извезену и државно-контролисану просторну
манифестацију, са јасним циљевима који одражавају тежње
политике културне размене. Уводи се и појам архитектуре
као инструмента преговарања између различитих
актера, интерпретирајући дефиницију појма „soft power“
Џозефа С. Наја, која је дата, у најосновнијим цртама, као
способности привлачења, са привлачношћу која често
води ка прихватању ставова друге стране. Ове типологије
могу имати снажан утицај по више основа, првенствено на
просторну интеракцију и националну репутацију, међутим,
креатори политике и стратегија остају несвесни важности
раније поменутих архитектонских манифестација као
културних ресурса. Чланак ће поставити теоретске оквире

студије случаја нове јапанске амбасаде у
Београду, примећује се специфичност њених управљачких
процеса као и новонасталих просторних последица,

Organski i prirodni kozmetički proizvodi ‐ ko ima najviše koristi od njih?
A demand for natural cosmetic products is increasing, especially in the EU countries
and the rest of the world, as the consumer awareness has increased for the preservation of
the environment and natural resources, but above all with the belief that these products are
safe and “healthy”. The current regulations on cosmetic products in the EU and the Republic
of Serbia do not recognize organic and natural cosmetic products as a special category, so
these products must meet all the requirements of these regulations in terms of quality,
efficacy and safety. However, due to the great interest of consumers and manufacturers,
there is a need to adopt special (additional) requirements for organic and natural cosmetic
products. Although, for now, there are no mandatory international regulations in this area,
the most important standards are: COSMOS, NATRUE and ISO 16128 (1-3). Despite certain
differences, these standards stand out in terms of their main objectives: promoting the use of
organic agriculture products, and respecting biodiversity, responsible use of natural
resources and respecting the environment, using processing and manufacturing that are
clean and respectful of human health and the environment, and integrating and developing
the concept of "Green Chemistry" (3).
Organic and natural cosmetic products are made from selected raw materials, most
often of plant origin, that are allowed for their production and processed with permitted
physical and chemical processes. The use of ingredients of animal origin is also allowed, if
that ingredient is produced by an animal naturally (it must not be part of an animal), such as
lanolin, beeswax, honey. The use of the ingredient from petrochemical origin (liquid and
solid paraffin, petrolatum/ white soft paraffin), silicone oils, nanomaterials, ingredients that
are GMOs, synthetic fragrances, dyes and preservatives are forbidden (1).
Great attention is paid to the packaging of organic and natural cosmetic products. The
amount of packaging material should be reduced to the minimum necessary, and the amount
of packaging material that can be reused or recycled should be increased. The use of plastic
materials (PVC, polystyrene, etc.), which are not biodegradable is forbidden (3).
Today, the quality, efficacy and safety of all cosmetic products are taken for granted.
However, the use of organic and natural cosmetic products has a great impact on the
preservation of the environment and natural resources. The adoption of binding
international legal regulations in this area is very important.Povećana potražnja za prirodnim i organskim kozmetičkim proizvodima, u zemljama
EU i u svetu, posledica je porasta svesti potrošača za očuvanjem životne sredine i prirodnih
resursa, ali i verovanjem da su ti proizvodi „zdraviji“ i bezbedniji u poređenju sa
konvencionalnim kozmetičkim proizvodima. Važeći zakonski propisi o kozmetičkim
proizvodima u zemljama EU i Republici Srbiji ne prepoznaju organske i prirodne kozmetičke
proizvode kao posebnu kategoriju, pa i ovi proizvodi moraju zadovoljiti sve zahteve
zakonskih propisa u pogledu kvaliteta, efikasnosti i bezbednosti. Međutim, zbog velike
zainteresovanosti potrošača i proizvođača nametnula se potreba za usvajanjem posebnih
(dodatnih) zahteva za organske i prirodne kozmetičke proizvode. Iako, za sada, ne postoje
obavezujući međunarodni zakonski propisi u ovoj oblasti, najznačajnijim se mogu smatrati
standardi: COSMOS (od 2010. godine), NATRUE (od 2007. godine) i ISO 16128 (1-3). Prvi
deo ISO standarda 16128 (Definicije sastojaka) usvojen je 2016. godine, a drugi (Kriterijumi
za sastojke i proizvode) 2017. godine. Iako se očekivalo da će usvajanje ISO standarda bliže
urediti ovu oblast, predstavnici vodećih evropskih udruženja za prirodne i organske
kozmetičke proizvode navode da ISO standard 16128 ima brojne nedostatke (1). I pored
određenih razlika, navedeni standardi kao svoje glavne ciljeve ističu odgovorno korišćenje
prirodnih resursa i poštovanje životne sredine, korišćenje postupaka koji su „čisti“ i koji
poštuju zdravlje ljudi i životnu sredinu, kao i integrisanje i razvoj koncepta "Zelene hemije"
(3).
Organski i prirodni kozmetički proizvodi se izrađuju od odabranih sirovina, najčešće
biljnog porekla (npr. biljni ekstrakti, biljna ulja, masti i voskovi, masne kiseline i masni
alkoholi, etarska ulja i dr.) koje su dozvoljene za njihovu izradu i obrađene dozvoljenim
fizičkim i hemijskim postupcima. Dozvoljena je i upotreba sastojaka životinjskog porekla,
ukoliko je taj sastojak proizvod životinje (npr. lanolin, pčelinji vosak, med), a ne sme biti deo
životinje. Zabranjena je upotreba sirovina dobijenih iz nafte (tečni i čvrsti parafin,
petrolatum/vazelin), silikonskih ulja, nanomaterijala, genetski modifikovanih sirovina,
sintetičkih mirisa, boja i konzervanasa (1).
Pakovanju organskih i prirodnih kozmetičkih proizvoda se posvećuje velika pažnja.
Količinu pakovnog materijala treba svesti na neophodni minimum, a treba povećati količinu
materijala za pakovanje koji se može ponovo upotrebiti ili reciklirati. Zabranjena je upotreba
plastičnih materijala (PVC, polistiren i dr.), koji nisu biodegradabilni (3).
Danas se kvalitet, efikasnost i bezbednost svih kozmetičkih proizvoda podrazumeva.
Ali, upotreba organskih i prirodnih kozmetičkih proizvoda ima veliki uticaj na očuvanje
životne sredine i prirodnih resursa. Zato je usvajanje obavezujućih međunarodnih zakonskih
propisa u ovoj oblasti od izuzetnog značaja.Drugi naučni simpozijum Saveza farmaceutskih udruženja Srbije sa međunarodnim učešćem, 28. 10. 2021. Beogra
Photocatalytic activity induced by zinc phthalocyanine synthesized by microwave irradiation
Zinc phthalocyanine, synthesized under microwave irradiation proved to be an interesting photocatalyst. The degradation of Rose Bengal, as model organic dye, under visible light irradiation was used to study the adsorption/photocatalytic activity. The huge potential of the synthesized molecule for the removal of organic pollutants was demonstrated by its absorption capacity, which was far larger than that of dye degradation
A fast and efficient synthesis of gamma rays dosimeters based on metalophthalocyanines
The area of radiation protection has gained significant relevance due to the fast advancement of radiation technology and its utilization in scientific research. In order to meet the low doses of nuclear radiation, such as gamma (γ)-rays, development of great fineness, stable, and reliable sensors are required. The heterocyclic compounds known as metallophthalocyanines (MPcs) won considerable research interest owing to their exceptional thermal, chemical and photo-stability, and long wavelength absorption compatible with biological window, spreading their potential applications in technology and medicine. As a result, finding the ideal method for creating such molecules is always in the spotlight. In this work, we designed a novel and efficient microwave-assisted synthetic method for preparation of innovative sensor materials base on MPcs (M = Zn, Mn or Fe). A zinc phthalocyanine has been evaluated as model compound in preparing ZnPc/PVA composites as a new, effective chemical-based dosimeter for low-dose measurement of γrays within the dose range from 1-25 kGy. A microwave-enhanced synthetic approach has been evaluated as an impressive chemical-based dosimeter designer. A modest decrease in absorbance intensity, followed by color bleaching in the dose range of 1-25 kGy, enabled the preparation of ZnPc/PVA composites as fine, glossy surface films with impressive application in gamma-ray dosimetryTwenty-First Young Researchers’ Conference - Materials Science and Engineering: Program and the Book of Abstracts; November 29 – December 1, 2023, Belgrade, Serbi
Synthesis of bile acid amines via microwave irradiation
Herein, we present microwave-assisted reductive amination of oxo derivative of deoxycholic acid with morpholine in the presence of sodium-cyanoborohydride. These chemical transformation produces a majority of the 3β-amino isomer 5 as a new compound after five minutes of irradiation. In addition, formylated bile acid have been proved as excellent starting material for the synthesis of bile acid`s N-morpholino amine. Microwave-assisted reactions of formylation in the absence of catalyst, selective deformylation, as well as further oxidation with N-bromosuccinimide gained 3-oxo derivatives of deoxycholic acid acid in high yield. Compared to the conventional protocol a remarkable reduction in overall processing time from hours to a few minutes was achieved
Green infrastructure
Urban green areas have been treated as a part of the urban public space. In oposition to
the other public spaces, green areas are mainly covered with vegetation. Directly, they
have been in use for active or passive recreation, while, indirectly, they are significant
because of their contribution to the quality of the urban environment also. Various
functions of the green spaces (health, social, aesthetic, cultural, educational, etc.)
improve the quality of life in the city. Green areas should be well positioned and
incorporated in the fabric of the city in order to be available to residents of the city.
Urban green spaces are important elements of each city. They represent of the image of
the city, expanding ecological diversity and, in their essence, they are structural and
functional elements that make cities and urban regions more suitable for living
Change of the image of the city in process of using traffic infrastructure
Unique urban image cannot be experienced without moving within its structure. This paper deals with phenomenology considering changes of images of the city and influential factors closely related to it. Infrastructure gives basic structural scheme of every city, so its planning requires a high level proficiency. Some changes in these images can be observed during longer period of time. Sometimes it includes rapid changes of temporal layers, generated by building new urban elements on the exact same place where the old ones existed; while lighter change during the time passing is a regular occurrence. Creating completely new urban frames, caused by expanding the city, represents its dynamical variant. Topography is a significant factor, giving distinctive feature to the urbanity. This paper considers factors identified as generators of the change of the urban image, based on research so far. The structural elements are considered with the utmost attention. The importance of the city landmark, monumental complexes not possessing these features but having the importance in image of the city stability (as well as the inhabitants' memory) are crucial elements of identifying its picture. Another significant factor is related to individual personal experience. However, there are also certain factors of significance features, but not considered within this paper. One such factor is change in coloring, being the special topic itself. The purpose of this work is to indicate that urban planning requires special attention in order to keep continuous nature of the urban image for the city to preserve its visual identity
Contemporary Serbian Orthodox church architecture: Architectural competitions since 1990
This paper focuses on the architectural competitions for Orthodox Christian churches in Serbia since 1990, both on the analysis of the designs submitted and the competition requirements. The first competition for an Orthodox church in Serbia after World War II was announced for Priština in 1991. After that, competitions for the temple in Čukarica, Novi Beograd, Niš, Aleksinac and Kruševac were conducted. Thanks to the fact that architectural competitions allow a greater degree of creative freedom to the architects than regular practice, various solutions were offered, from replicas of models from architectural history and tradition to fully non-traditional proposals. Depending on the relationship to tradition, architectural design approaches can be classified into three main groups: radically modernizing, conservatively traditionalist, and compromising. Of the six competitions conducted, four churches were built, which are among the most architecturally successful newer churches in Serbia. This points to the importance of the implementation of the architectural competition in this field of architecture. The diversity of the award-winning projects shows that there is awareness of the possibility for the further development of church architecture, favouring a moderate approach
Mehanička svojstva i dugotrajna stabilnost novih lipidnih formulacija sa simvastatinom
Mixing selected liquid SMEDDS with polymethacrylate polymers (Eudragit ®) led to
solidification of the samples to form solid, ductile, transparent systems (1). The purpose of
this study was to define mechanical properties and long-term stability of novel simvastatin-
loaded SMEDDS-based drug delivery systems. SMEDDS-based formulations were prepared
by adding liquid SMEDDS (10% oleoyl macrogol-6 glycerides and 90% caprylocaproyl
macrogol-8 glycerides/macrogol-15-hydroxystearate, in 3 ratios: 1:1, 2:1 and 3:1) to
Eudragit ® S100 or Eudragit ® S100/Eudragit ® L100 combination (in 1:1 ratio), until
SMEDDS/polymer ratio 2:1 w/w was reached. SMEDDS-based formulations with simvastatin
(SV) were prepared by dissolving SV (5%) into liquid SMEDDS and mixing with
polymethacrylate polymers in the same ratio. Prepared formulations were evaluated in
terms of their mechanical properties and long-term stability. The results indicated that the
increase in the caprylocaproyl macrogol-8 glycerides concentration resulted in higher
penetration force (F1 S100–F3 S100 = 5.83-7.22 N and F1 SL100-F3 SL100 = 4.20-5.99 N).
However, addition of SV was negatively correlated with the hardness, i.e. samples with SV
were softer in comparison to unloaded samples. Moreover, it was noticeable that
formulations with Eudragit ® S100 had greater penetration force values compared to
formulations containing Eudragit ® S100/Eudragit ® L100. After six months of storage at
room and elevated temperature, only slight decrease in SV content (less than 5%) was
observed in these samples. This study demonstrated that novel SMEDDS-based formulations
with higher concentration of caprylocaproyl macrogol-8 glycerides and those with Eudragit ®
S100 were more robust, which may further serve as a guide for formulating tailor-made
formulations.Mešanje odabranih tečnih samomikroemulgujućih sistema (SMEDDS) sa
kopolimerima metakrilne kiseline (Eudragit ® ) dovodi do očvršćavanja uzoraka i formiranja
čvrstih, rastegljivih, transparentnih sistema (1). Cilj ovog rada je bio ispitivanje mehaničkih
svojstva i dugotrajne stabilnosti novih lipidnih sistema sa simvastatinom (SV). Lipidne
formulacije su izrađene mešanjem tečnih SMEDDS (10% oleoil makrogol-6 glicerida i 90%
kaprilokaproil makrogol-8 glicerida/makrogol-15-hidroksistearat, u 3 odnosa: 1:1, 2:1 i 3:1)
i Eudragit ® S100 ili kombinacije Eudragit ® S100/Eudragit ® L100 (u odnosu 1:1). Odnos
SMEDDS/polimer bio je 2:1, m/m. Uzorci sa SV su izrađeni rastvaranjem SV (5%) u tečnim
SMEDDS i mešanjem sa kopolimerima metakrilne kiseline u navedenom odnosu. Sprovedena
su ispitivanja mehaničkih osobina i dugotrajne stabilnosti izrađenih lipidnih formulacija.
Rezultati su pokazali da povećanje koncentracije kaprilokaproil makrogol-8 glicerida dovodi
do povećanja vrednosti sile penetracije (F1 S100–F3 S100 = 5,83-7,22 N i F1 SL100-F3
SL100 = 4,20-5,99 N). Uzorci sa SV su bili mekši, u poređenju sa uzorcima bez lekovite
supstance. Takođe, uočeno je da uzorci sa polimerom Eudragit ® S100 imaju već e vrednosti
sile penetracije, u poređenju sa formulacijama koje sadrže kombinaciju Eudragit ®
S100/Eudragit ® L100. Posle šest meseci skladištenja uzoraka na sobnoj i povišenoj
temperaturi, sadržaj SV je neznatno smanjen (manje od 5%). Ova studija je pokazala da nove
lipidne formulacije izrađene sa većom koncentracijom kaprilokaproil makrogol-8 glicerida i
sa Eudragit ® S100 polimerom imaju veće vrednosti sile penetracije i prihvatljivu dugotrajnu
stabilnost, što je od značaja za razvoj lipidnih formulacija željenih karakteristika.VIII Kongres farmaceuta Srbije sa međunarodnim učešćem, 12-15.10.2022. Beogra
