description: We derived radial velocities and CaT metallicity of more than 150 red giants stars in six SMC star clusters and their surrounding fields, with the instrument GMOS on GEMINI-S. The mean cluster radial velocity and metallicity were obtained with mean errors of 2.2 km\,s$^{-1}$ and 0.03 dex, while the mean field metallicities have a mean error of 0.13 dex. We add this information to that available for another 51 clusters and 30 fields with CaT metallicities on the same scale. Using this expanded sample we analize the chemical properties of the SMC Main Body, defined as the inner 3.4 degrees in semimajor axis. We found a high probability that the metallicity distribution of the Main Body clusters is bimodal with a metal-rich and a metal-poor cluster group, having mean metallicities with a dispersion of $μ= -0.80$, $σ= 0.06$ and $μ= -1.15$, $σ= 0.10$ dex, respectively. On the other hand, Main Body field stars show a unimodal metallicity distribution peaking at $[Fe/H] \sim -1$ and dispersion of $0.3$. Neither metal-rich nor metal-poor clusters present a metallicity gradient. However the full Main Body cluster sample and field stars have a negative metallicity gradient consistent with each other, but the one corresponding to clusters has a large error due to the large metallicity dispersion present in the clusters studied in that region. Metal-rich clusters present a clear age-metallicity relation, while metal-poor clusters present no chemical enrichment throughout the life of the galaxy. We present observational evidence that the chemical enrichment is complex in the SMC Main Body. Two cluster groups with potential different origins could be coexisting in the Main Body. More data with precise and homogeneous metallicities and distances are needed and dynamical simulations are required to understand possible different origins for the two possible cluster groups.

description: One of the key characteristics of cancer cells is an increased phenotypic plasticity, driven by underlying genetic and epigenetic perturbations. However, at a systems-level it is unclear how these perturbations give rise to the observed increased plasticity. Elucidating such systems-level principles is key for an improved understanding of cancer. Recently, it has been shown that signaling entropy, an overall measure of signaling pathway promiscuity, and computable from integrating a sample's gene expression profile with a protein interaction network, correlates with phenotypic plasticity and is increased in cancer compared to normal tissue. Here we develop a computational framework for studying the effects of network perturbations on signaling entropy. We demonstrate that the increased signaling entropy of cancer is driven by two factors: (i) the scale-free (or near scale-free) topology of the interaction network, and (ii) a subtle positive correlation between differential gene expression and node connectivity. Indeed, we show that if protein interaction networks were random graphs, described by Poisson degree distributions, that cancer would generally not exhibit an increased signaling entropy. In summary, this work exposes a deep connection between cancer, signaling entropy and interaction network topology.

description: We propose to jointly explain the electron/muon $g-2$ anomalies in the framework of anomaly mediated SUSY breaking (AMSB) scenario. Two Yukawa deflected AMSB models are proposed and discussed in depth: one with lepton-specific interactions and the other one with messenger-matter interactions. Both models are found to be able to jointly explain the anomalies at $2 σ$ level by naturally realizing the preferred parameter space with $μM_1,μM_2<0$ and very heavy left-handed smuon.

description: Abstract Aim: The World Health Organization (WHO) publishes a large number of health reports every year, containing recommendations to overcome societal and system barrier challenges toward targeting unmet health needs. One such report, the International Perspectives on Spi-nal Cord Injury (IPSCI), specifically describes the situation of persons with spinal cord in-jury. Against this backdrop, the question arises about how these recommendations can be incorporated into an implementation strategy. Therefore, the aim of this paper is to describe a phased process of developing an implementation strategy for a WHO public health report with IPSCI serving as a case example. Methods: The process to develop the implementation strategy consisted of specific phases each employing particular mechanisms. The preparatory phase was composed of a group dis-cussion to select development mechanisms. The implementation strategy development phase comprised focus-group interviews, as well as of a stakeholder dialogue. Thematic content analysis was applied to qualitative data. Results: The group discussion led to selection of specific development mechanisms. The focus group mechanism allowed key stakeholders to openly discuss implementation goals and processesand impacted the selection of the core implementation group members and the focus of the stakeholder dialogue (SD) discussion.The SD was instrumental in developing a specific implementation strategy based on the report‟s recommendations. The strategy con-sisted of a detailed implementation plan, provisions to coordinate an implementation group and expert guidance. Conclusion: The findings from the current study can inform the ongoing development of systematic, evidence-informed, participatory and stakeholder-driven processes for the devel-opment of implementation strategies for recommendations from WHO public health reports.

description: The $^{26}$Al short-lived radioactive nuclide is the source of the observed galactic diffuse $γ$-ray emission at 1.8 MeV. While different sources of $^{26}$Al have been explored, such as AGB stars, massive stars winds, and supernovae, the contribution of very massive stars has never been studied. We study the stellar wind contribution of very massive stars, i.e stars with initial masses between 150 and 300 M$_\odot$, to the enrichment in $^{26}$Al of the galactic interstellar medium. We discuss the production of $^{26}$Al by studying rotating and non-rotating very massive stellar models with initial masses between 150 and 300 M$_\odot$ for metallicities Z=0.006, 0.014, and 0.020. We confront this result to a simple Milky Way model taking into account both the metallicity and the star formation rate gradients. We obtain that very massive stars in the Z=0.006-0.020 metallicity range might be very significant contributors to the $^{26}$Al enrichment of the interstellar medium. Typically, the contribution of the winds of massive stars to the total quantity of $^{26}$Al in the Galaxy increases by 150\% when very massive stars are considered. Very massive stars, despite their rarity, might be important contributors to $^{26}$Al and overall very important actors for nucleosynthesis in the Galaxy.

God inklusion i målingens tidsalder
Creators: name: Engsig, Thomas Thyrring
Publisher: name: CEPRA-striben
Year: 2022

description: Inklusionsforskningen er i krise grundet såvel konceptuelle som metodiske genvordigheder. Som følge heraf fordres det, i den internationale inklusionsforskning, at denne bevæges mod en empirisk vending, som skal styrke inklusionsforskningen selv, men ligeledes styrke mulighederne for at teste og måle inklusionsindsatser i skolen. Ønsket om i højere grad at kunne måle inklusion er udtryk for et dilemmafyldt krydspres mellem agendaen om inklusion og en mere neoliberal agenda. Dette krydspres synes at presse skolens fagprofessionelle; deres opmærksomhed vendes væk fra inklusionsbestræbelserne. I nærværende artikel diskuteres dette krydspres, og der argumenteres for, at vi nødvendigvis må stille spørgsmålet, hvorvidt inklusion kan endsige skal indtræde i målingens tidsalder. På den baggrund præsenteres modellen CESA3, der tilbyder en analytisk ramme til empiriske undersøgelser af inklusion i komplekse pædagogiske og didaktiske sammenhænge. Modellen er en anerkendelse af, at vi har brug for mere konkrete bud på rammesætninger til at stille pædagogiske spørgsmål om inklusion i skolen.

description: Starting point of this paper is the prevailing view in the digitization discourse that there is currently a pronounced technology push with disruptive consequences for work. The article argues, however, that disruptive and structural change is by no means to be found or expected in all economic sectors and working segments. The thesis of this paper is that the digitization of work in the sector of industrial production is tied to a markedly path-dependent process of technological innovation and transformation of work. It is shown empirically that path dependency can be identified by incremental digitization measures in most companies and a related structurally conservative change in work. To explain these findings, conceptual considerations of organizational path dependence are invoked which emphasize particularly the mechanism of self-reinforcing increasing returns. However, technological and organizational path-dependency does not exclude the possibility of disruptive change. Therefore, the empirical and theoretical preconditions for longer-term disruptive change in work processes are discussed in conclusion.

description: Exoplanetary properties depend on stellar properties: to know the planet with accuracy and precision it is necessary to know the star as accurately and precisely as possible. Our immediate aim is to characterize in a homogeneous and accurate way a sample of 27 transiting planet-hosting stars observed within the GAPS program. We determined stellar parameters (effective temperature, surface gravity, rotational velocity) and abundances of 26 elements (Li,C,N,O,Na,Mg,Al,Si,S,Ca,Sc,Ti,V,Cr,Fe,Mn,Co,Ni,Cu,Zn,Y,Zr,Ba,La,Nd,Eu). Our study is based on high-resolution HARPS-N@TNG and FEROS@ESO spectra and uniform techniques. We derived kinematic properties from Gaia data and estimated for the first time in exoplanet host stars ages using elemental ratios as chemical clocks. Teff of our stars is of 4400-6700 K, while [Fe/H] is within -0.3 and 0.4 dex. Lithium is present in 7 stars. [X/H] and [X/Fe] abundances vs [Fe/H] are consistent with the Galactic Chemical Evolution. The dependence of [X/Fe] with the condensation temperature is critically analyzed with respect to stellar and kinematic properties. All targets with measured C and O abundances show C/O<0.8, compatible with Si present in rock-forming minerals. Most of targets show 1.0

description: In line with the building needs arising with the increase in industrialization in Hadımköy district, the tendency towards steel construction has increased significantly. The aim of this study is to reveal the necessity of building industrial buildings with steel construction in order to prevent disaster and soil problems in Hadımköy region. For this purpose, three factory examples from the Hadımköy region, which were partially or completely built with steel construction, were discussed. The evaluations made on these examples aim to qualitatively examine the hardware features of the construction in line with the changing needs of the industry. In this context, two buildings with different functions were evaluated and analyzed in terms of structural quality, flexibility, sustainability, durability and resistance to disasters. In line with the findings, it has been determined that the construction of industrial buildings in accordance with the changing needs of industrial buildings is provided by the use of steel construction system. The result of this study is an important reference in terms of preventing disasters and soil problems in the region by increasing the use of steel construction structures in regions with dense industrial buildings such as Hadımköy district.

description: Dementia effects our ability to think abstractly and social or daily abilities. It also eliminates similar abstract concepts, such as integration with design and perception of spatial and temporal orientation. The study aims to create a design idea focusing on discovering and improving the relationships that individuals with dementia have with the city. This study was conducted within design urban space through neurobiological and behavioural studies on Dementia. Data was collected via literature review, case studies, observations and interviews and it was evaluated via a design perspective. A relationship was observed between the lives, spatial relationships, commodities, and equipment of individuals with dementia-type diseases at the social and individual scale. It was also discovered that the subject should be handled in terms of the design content along with how it should be handled. As a result, a new design strategy was presented as a design behaviour model without prior knowledge.

Increased mass loss and asynchronous behavior of marine-terminating outlet glaciers at Upernavik Isstrøm, NW Greenland: UPERNAVIK ISSTRØM

description: In order to model and predict future behavior of marine terminating glaciers, it is essential to understand the different factors that control a glaciers response to climate change. Here we present a detailed study of the asynchronous changes in dynamic behavior of four adjacent marine-terminating glaciers at Upernavik Isstrøm (UI), Northwest Greenland, between 1992 and 2013. Velocities were stable for all outlets at UI between 1992 and 2005. The northernmost glacier started to accelerate and thin in 2006 and continued to do so into 2011 after which time the velocities stabilized. The second most northerly glacier started to accelerate and thin in 2009 and continued to do so until the last observations in 2013, dramatically increasing the area affected by dynamically induced thinning. The southern glaciers show little change, with the most southerly glacier undergoing slight retreat and deceleration between 1992 and 2013. These observations point out the fact that the UI glaciers are reacting to climate change on different timescales. The asynchronous behavior of the four neighboring glaciers is explained in terms of the individual glaciersâĂŹ geometry and terminus position. The northernmost glacier is believed to have had a floating tongue between 1985 and 2007 which disintegrated in 2007-2008. This release of back stress destabilized the glacier causing it to accelerate and thin rapidly. We suggest that the ice tongue broke up due to ocean-warming induced thinning in the late 1990s. Recent response on UI glaciers is found to be related to increased surface melt. Our investigations suggest that three out of the four main glaciers in the UI are likely to be in unstable positions and may have the potential to rapidly thin and accelerate and increase their contribution to sea level in the future.

We compute the finite effective potential of ${\cal N}=8$ anti-deSitter supergravity and interpret it as logarithmic running of the cosmological constant. We find that quantum inequivalence between fields that are classically dual is due to boundary modes in AdS$_4$. Some subtleties are traced to the difference between the Euler characteristic of global and thermal AdS$_4$.

description: Convection is ubiquitous in stars and occurs under many different conditions. Here we explore convection in main-sequence stars through two lenses: dimensionless parameters arising from stellar structure and parameters which emerge from the application of mixing length theory. We first define each quantity in terms familiar both to the 1D stellar evolution community and the hydrodynamics community. We then explore the variation of these quantities across different convection zones, different masses, and different stages of main-sequence evolution. We find immense diversity across stellar convection zones. Convection occurs in thin shells, deep envelopes, and nearly-spherical cores; it can be efficient of inefficient, rotationally constrained or not, transsonic or deeply subsonic. This atlas serves as a guide for future theoretical and observational investigations by indicating which regimes of convection are active in a given star, and by describing appropriate model assumptions for numerical simulations.

Does health sector aid matter? Evidence from time-series data analysis in Ethiopia
Creators: name: Gutema, Keneni

Publisher: name: South Eastern European Journal of Public Health (SEEJPH)
Year: 2018

description: Aims: Development assistance for health is an important part of financing health care in developing countries. In spite of the increasing volumes in absolute terms in development assistance for health, there are controversies on their effect on health outcomes. Therefore, this study aims to analyze the effect of development assistance for health on health status in Ethiopia. Methods: Using dynamic time series analytic approach for the period 1978-2013, this paper examines whether development assistance for health has contributed for health status change in Ethiopia. While life expectancy at birth was used as a measure of health status, vector error correction model was used for the analysis. Results: Development assistance for health expenditure (lagged one and two years) had a significant positive effect on life expectancy at birth in Ethiopia. Other things being equal, a 1% increase in per capita development assistance for health leads to 0.026 years improvement in life expectancy at birth (P<0.001) in the immediate year following the period of assistance, and 0.008 years (P=0.025) in the immediate two years following the provision of assistance. Conclusion: This study indicates that, seemingly, development assistance for health has significant favourable effect in improving health status in Ethiopia. The policy implication of this finding is development assistance for the health should continue as an interim means to an end.

description: A self-consistent pre-inflationary extension of the inflationary scenario with the Starobinsky potential, favored by Planck data, is studied using techniques from loop quantum cosmology (LQC). The results are compared with the quadratic potential previously studied. Planck scale completion of the inflationary paradigm and observable signatures of LQC are found to be robust under the change of the inflaton potential. The entire evolution, from the quantum bounce all the way to the end of inflation, is compatible with observations. Occurrence of desired slow-roll phase is almost inevitable and natural initial conditions exist for both the background and perturbations for which the resulting power spectrum agrees with recent observations. There exist initial data for which the quantum gravitational corrections to the power spectrum are potentially observable.

description: With an unprecedented astrometric and photometric data precision, Gaia EDR3 gives us, for the first time, the opportunity to systematically detect and map in the optical bands, the low mass populations of the star forming regions (SFRs) in the Milky Way. We provide a catalogue of the Gaia EDR3 data (photometry, proper motions and parallaxes) of the young stellar objects (YSOs) identified in the Galactic Plane (|b|<30 deg) within about 1.5 kpc. The catalogue of the SFRs to which they belong is also provided to study the properties of the very young clusters and put them in the context of the Galaxy structure. We applied the machine learning unsupervised clustering algorithm DBSCAN on a sample of Gaia EDR3 data photometrically selected on the region where very young stars (t<10 Myr) are expected to be found, with the aim to identify co-moving and spatially consistent stellar clusters. A subsample of 52 clusters, selected among the 7323 found with DBSCAN, has been used as template data set, to identify very young clusters from the pattern of the observed color-absolute magnitude diagrams through a pattern match process. We find 124440 candidate YSOs clustered in 354 SFRs and stellar clusters younger than 10 Myr and within about 1.5 Kpc. In addition, 65863 low mass members of 322 stellar clusters located within about 500 pc and with ages 10 Myr

description: It is aimed to rank the installation forms in terms of the entrance area in terms of which actions should be at the forefront in the organization of the space, and to examine them in order of importance, to analyze and report on the selected shopping centers comparatively. Known as a temporal and perceptual concept that connects the sequences of spaces or different indoor and outdoor environments, circulation is one of the broad and very important issues in architecture and has become a design discipline that must be done within the framework of certain standards. In looking at the circulation structure framework, the way it is perceived, its main components, forms, horizontal and vertical planes and phases during use all play an important role in architecture.In this research, the relationship and interaction with the user, functionality requirements and accessibility levels of selected shopping malls in terms of circulation integration, for example; the relationship of the orientation areas from the main entrance of the shopping mall to the supermarket entrances with circulation or the parking area and the circulation line of the users will be. In this research, it is aimed to review the literature, examine selected venues (Kanyon Mall, Zorlu Center Mall) in the context of the principles of the circulation layouts, observe the clarity and perceptibility levels of the venue, document it by taking photographs from the selected places, and examine the examples.

description: The Windjana drill sample, a sandstone of the Dillinger member (Kimberley formation, Gale Crater, Mars), was analyzed by CheMin X‐ray diffraction (XRD) in the MSL Curiosity rover. From Rietveld refinements of its XRD pattern, Windjana contains the following: sanidine (21% weight, ~Or95); augite (20%); magnetite (12%); pigeonite; olivine; plagioclase; amorphous and smectitic material (~25%); and percent levels of others including ilmenite, fluorapatite, and bassanite. From mass balance on the Alpha Proton X‐ray Spectrometer (APXS) chemical analysis, the amorphous material is Fe rich with nearly no other cations—like ferrihydrite. The Windjana sample shows little alteration and was likely cemented by its magnetite and ferrihydrite. From ChemCam Laser‐Induced Breakdown Spectrometer (LIBS) chemical analyses, Windjana is representative of the Dillinger and Mount Remarkable members of the Kimberley formation. LIBS data suggest that the Kimberley sediments include at least three chemical components. The most K‐rich targets have 5.6% K2O, ~1.8 times that of Windjana, implying a sediment component with >40% sanidine, e.g., a trachyte. A second component is rich in mafic minerals, with little feldspar (like a shergottite). A third component is richer in plagioclase and in Na2O, and is likely to be basaltic. The K‐rich sediment component is consistent with APXS and ChemCam observations of K‐rich rocks elsewhere in Gale Crater. The source of this sediment component was likely volcanic. The presence of sediment from many igneous sources, in concert with Curiosity's identifications of other igneous materials (e.g., mugearite), implies that the northern rim of Gale Crater exposes a diverse igneous complex, at least as diverse as that found in similar‐age terranes on Earth.

description: The aim of the study is to evaluate the latest developments in floating architecture examples and to show the importance of the themes of mobility and inflatability in the evolution of the architectural image related to floating structures in terms of future architectural products. The scope of the study includes studies of theoretical figures, including floating architecture examples and detailed theoretical explanations about these examples. The method of the study was determined as literature review. In this way, prominent examples and works are evaluated and compared. The original value of the study is important in terms of evaluating a niche subject such as floating structures with the subheading of "architectural image" in terms of two basic topics such as mobility and inflatability. The findings of the study include data that the floating structures image will become widespread enough to be used in all spatial functions in future architectural productions through mobility and inflatability. As a result, the evolution of the architectural image of floating structures through mobility and inflatability themes create a contemporary template for the future possibilities of housing, urban areas, healthcare and educational facilities, accommodation and related functions including the flexible combinations of floatable structures. All of these point to a future where, in near future scenarios, water will be used actively not only at water edges through floating structures, but also in daily life, in many cases where water is associated with crises and natural disasters, but these processes are prolonged. This contains clues that a production area that strengthens the architectural image of floating structures and carries it into the future will gradually spread to a wider area.

description: Globular clusters (GCs) are thought to harbor the long-sought population of intermediate-mass black holes (IMBHs). We present a systematic search for a putative IMBH in 81 Milky Way GCs, based on archival Chandra X-ray observations. We find in only six GCs a significant X-ray source positionally coincident with the cluster center, which have 0.5-8 keV luminosities between $\sim1\times 10^{30}~{\rm erg~s^{-1}}$ to $\sim 4\times10^{33}~{\rm erg~s^{-1}}$. However, the spectral and temporal properties of these six sources can also be explained in terms of binary stars. The remaining 75 GCs do not have a detectable central source, most with $3σ$ upper limits ranging between $10^{29-32}~{\rm erg~s^{-1}}$ over 0.5-8 keV, which are significantly lower than predicted for canonical Bondi accretion. To help understand the feeble X-ray signature, we perform hydrodynamic simulations of stellar wind accretion onto a $1000~{\rm M_\odot}$ IMBH from the most-bound orbiting star, for stellar wind properties consistent with either a main-sequence (MS) star or an asymptotic giant branch (AGB) star. We find that the synthetic X-ray luminosity for the MS case ($\sim 10^{19}\rm~erg~s^{-1}$) is far below the current X-ray limits. The predicted X-ray luminosity for the AGB case ($\sim 10^{34}\rm~erg~s^{-1}$), on the other hand, is compatible with the detected central X-ray sources, in particular the ones in Terzan 5 and NGC 6652. However, the probability of having an AGB star as the most-bound star around the putative IMBH is very low. Our study strongly suggests that it is very challenging to detect the accretion-induced X-ray emission from IMBHs, even if they were prevalent in present-day GCs.

description: Coronary heart disease remains the leading cause of death in the developed world. Advanced age is the single strongest risk factor for coronary artery disease (CAD) and independent predictor for poor outcomes following an acute coronary syndrome (ACS). ACS refers to a spectrum of conditions compatible with acute myocardial ischemia and/or infarction due to various degrees of reduction in coronary blood flow as a result of plaque rupture/erosion and thrombosis formation or supply and demand mismatch. Unstable angina and non-ST segment elevation myocardial infarction are often continuous and clinically indistinguishable, collectively referred as non-ST elevation ACS (NSTE-ACS). An abrupt total occlusion of a coronary artery causing transmural myocardial ischemia/necrosis and displaying ST segment elevation or new left bundle branch block on a12-lead ECG leads to the diagnosis of ST segment elevation myocardial infarction (STEMI). NSTE-ACS and STEMI require acute cardiac care. Professional societies have established guidelines for high quality contemporary care for ACS patients, i.e., American Heart Association/American College of Cardiology guidelines for STEMI and NSTE-ACS, European Society of Cardiology guidelines for STEMI and NSTE-ACS, and the United Kingdom National Institute for Health and Care Excellence guidelines for STEMI and NSTE-ACS.[1]–[6] Implementation of evidence-based therapies has significantly decreased mortality and morbidities of ACS.[3],[7],[8] However, these advancements in ACS management have not equally improved outcomes for older adults. Vulnerable older patients continue to be at high risk of poor outcomes, are less likely to receive evidence based care, and have high mortality rates regardless of treatments given.[9],[10] These disparities and challenges in caring for ACS in older adults are well recognized.[11]–[13] This review summarizes the increasing burden and persistent unfavorable outcome of ACS in older adults, and discusses the clinical presentation, diagnosis and strategies for medical and invasive therapy.

description: Edirne, which was founded on the roads connecting the Asian and European continents, has been an important crossing point since the earliest times in history has hosted various civilizations for centuries and has acquired rich historical knowledge. Edirne, which was conquered by the Ottoman Empire in 1361 and later became the capital of the Ottoman Empire for approximately ninety years, has become a prominent center with its natal structure as well as politically and culturally, as it is the capital. After the Ottomans took the city, great importance was given to urban development, and water structures were built, especially the Selimiye and Eski, Üç Şerefeli Mosques, where many people stayed. The city of Edirne meets its water needs from the water resources around the city. The water from these sources is carried to the city through aqueducts and maksems, and their distribution within the city is provided by fountains. These fountains in the city house are small structures and are important structures in terms of the progress of their features. It continues to be built for six hundred years, with pieces exceeding thousands; However, these water structures, a small part of which survives today, have preserved the social and aesthetic strength of the city. This article aims to express the place of the structure in the history of the city and to explain the processes of examination, research, and repair work carried out on three fountain structures during the 16-year and 18-year period of the project, located in the Central District of Edirne Province. Key Words: Edirne, Fountain, Restoration, Water Structures

description: Based on taking advantage of the healing power and aesthetic wealth of nature, biophilic design theory has had an important place in the architectural literature for the last few decades. Previous studies suggested that biophilic design was not only a part of theoretical debate among scholars but also had practical implications. In fact, a wealth of studies suggested that buildings, and especially the interiors, designed upon biophilic design approach, sustained positive impact on the health and well-being of users and significantly increased the performance and creativity levels. In that regard, biophilic design can make a significant contribution to the development of creativity in design education setting. Furthermore, biophilic design can also provide guidance on how creativity should be incorporated into learning and teaching experiences. Therefore, inclusion of biophilic design in design education curriculum would be beneficial for both students and instructors. Although for centuries nature has been used as an aesthetic model for design, biophilic design has an important potential as a design education paradigm thanks to the fact that it has certain principles and a systematic. The present article aimed to introduce the biophilic design theory, underscore its significance, and suggest how the theory could make a contribution to learning and teaching processes by fostering creativity in interior design education setting. Accordingly, how biophilic design strategies nurtured and developed creative thinking skills was demonstrated on the basis of design outputs of the 6th semester interior design studio. The results suggested that the students included rich patterns of nature in their designs with an artistic sensitivity, used colors, textures, and motifs similar to those in nature, and showed a tendency to include visual folds and/or elevation differences in interiors similar to those found in nature. Furthermore, they exhibited better protective behavior towards the natural environment in their designs.
