An Alternative to Sea-Sun-Sand Tourism

Sedef DOGANER,Gulin BEYHAN 세계문화관광학회 2008 Conference Proceedings Vol.9 No.0

In the late 1970s Cohen argued that attention was being overly focused on tourism's negative effects. After that, several types of non-mass tourism such as 'alternative tourism' and 'ecotourism' were advocated as being less damaging to society and environment. In recent years, rural tourism has attracted a steadily increasing level of research attention, stimulated by two factors. First, tourism demand for rural areas is growing. Second, rural tourism has arrived on the political-economic agenda, the hope being that tourism business can alleviate the consequences of a decline in traditional means of rural employment. Varying degrees of rural areas tend to have four main qualities: relatively low physical densities of people, buildings and activities; less social and cultural heterogeneity; less economic diversity; and a comparative physical isolation from general economic, social and political networks. With the aim of improving the possibilities of alternative tourism in Antalya and accelerating the progress in rural areas by means of tourism, mountain villages are attempted to be brought in tourism guaranteed that all its local, social and cultural values kept. Mountain villages were settled by means of an architectural concern that gives priority to natural conditions and that is conscious of human-centered value judgments. By means of this study, necessity of regional protection that covers all the local, social and cultural entities is emphasized, and the importance of involvement within tourism in order to accelerate regional development is discussed.

The New Architourist Destination: Dallas/Fort Worth, Texas

Sedef Doganer 세계문화관광학회 2013 International Journal of Culture and tourism Resea Vol.6 No.1

This research discusses the relationships between the design of architecture, urban space and the contemporary practices of tourism. "Architourism"- Architecture as a Destination for Tourism -, which is defined by Ockman and Frausto in 2005, is also studied. Ockman and Frausa suggested that architecture itself has become a marketable destination today, and now architourism has its own niche in the tourist industry. Frank Gehry's Guggenheim Bilbao Museum is a good example of how architecture can turn around a city's fortunes. In this sense, this paper promotes Dallas/Fort Worth as an architourist destination. The research explores how Dallas/Fort Worth Area is transformed or revitalized around architourism, how it stimulates the creation of new masterpieces of architecture. The research also questions in what ways contemporary media culture, globalization, urbanism, and consuming economy have changed the relationship between architecture and tourism.

The New Architourist Destination: Dallas/Fort Worth, Texas

Sedef DOGANER. PhD 한국문화관광학회 2021 문화관광연구 Vol.23 No.2

Tourism has been an empowering phenomenon in our modern leisure oriented society, and become very important especially for politicians, economics and developers, as well as the urban planners and architects. Tourism has also a strong impact on architecture and urban space; approximately 63% of daily tourist activities are visiting famous places and urban spaces (Richter, 2010). In this context, this paper will discuss the relationships between the design of architecture, urban space and the contemporary practices of tourism. A relatively new term “Architourism” – Architecture as a Destination for Tourism –, which is coined by Ockman and Frausto in 2005, will also be studied.Ockman and Frausa suggested that architecture itself has become a marketable destination today, and now architourism has its own niche in the tourist industry. Frank Gehry s Guggenheim Bilbao Museum is a good example of how architecture can turn around a city s fortunes. All of these trends toward experiencing the architecture are allowing places such as Dallas and Fort Worth, Texasto augment and define tours that highlight the contributions that famous architects have made to the area, thus providing a valuable resource of revenue generation for the community.Dallas/Fort Worth Area Tourism Council (DFWATC) was formed in 1978 to be a comprehensive force within the tourism industry to jointly market the entire area as a single-destination. The Dallas/ Fort Worth Area Tourism Council has banded together all segments of the tourism industry. The Council represents area communities,area hotels, major area attractions, museums, restaurants, shopping/retail establishments, transportation companies and support services to the industry. In this sense,this paper will explore howDallas/Fort Worth Area is transformed or revitalized around architourism, how it stimulates the creation of new masterpieces of architecture, and some forms of “desire” that motivate architourism like authentic, exotic, escapist, and spectacular. It will also be questioned in what ways contemporary media culture,globalization, urbanism, and consuming economy have changed the relationship between architecture and tourism.

Experimental and factorial study on gas separation properties of PLA-based green composite membranes

Yılmaz Sedef Yüksel,Özen Hülya Aykaç,Geyikçi Feza 한국화학공학회 2023 Korean Journal of Chemical Engineering Vol.40 No.12

Polylactide acid (PLA) is a biocompatible sustainable material with notable characteristics due to its good mechanical properties and low environmental impact. The present study investigated the effects of PLA-based green membranes on gas separation and identified the best factor condition for the membrane. Prepared membranes were tested to determine oxygen (O2) and carbon dioxide (CO2) gas permeability properties. Oxygen gas permeability of the PLA/PEG/HA membrane obtained by drying for two days was increased from 100 kPa to 400 kPa; the permeability value of this membrane increased by 15%. On the other hand, the oxygen permeability value of the membrane prepared by dry for three days under the same pressure conditions and ambient temperature increased by 5%. This result indicates that the permeabilities of prepared membranes for O2 gas increase with increasing feed pressures. On the other hand, it was observed that the CO2 permeability decreased by 38.83% with the increase in pressure and drying time due to the plasticizing and swelling effect of carbon dioxide on the membrane. A factorial design was also constructed from experimental data and applied to determine the interactions of experimental parameters. All of the parameter interactions were of statistical significance for permeability. It is further argued that molecular weight has a significant positive effect on permeability, while dry time and pressure have just a slight negative effect. This study could contribute to further studies by reducing the number of tests necessary to understand the characteristics and gas separation performance of green materials.

Antioxidant and Antimicrobial Activities of Essential Oils Obtained from Oregano (Origanum vulgare ssp. hirtum) by Using Different Extraction Methods

Sibel Karakaya,Sedef Nehir El,Nural Karagözlü,Serpil Şahin 한국식품영양과학회 2011 Journal of medicinal food Vol.14 No.6

In this study, antioxidant and antimicrobial activities of essential oils obtained from oregano (Origanum vulgare ssp. hirtum) were determined by using solvent-free microwave extraction (SFME), supercritical fluid extraction, and conventional hydrodistillation (CH) methods. The inhibitory effects on the 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical of essential oils obtained from oregano by using SFME and CH were similar. However, essential oil extracted by CH showed greater (2.69 μmol/μL of oil) Trolox equivalent antioxidant capacity (TEAC) than oregano oils obtained by SFME (P < .05). The difference between percentage inhibition and TEAC values most probably is due to the fact that undiluted and diluted samples are used in the percentage inhibition assay and the TEAC assay, respectively. TEAC values of oregano essential oils obtained by SFME at different microwave power levels were found to be similar and ranged from 0.72 to 0.84 μmol/μL of oil. Essential oils obtained by CH and SFME at different microwave powers inhibited the survival of Listeria monocytogenes, Salmonella typhimurium, and Escherichia coli O157:H7, whereas survival of Staphylococcus aureus was not influenced. In addition, oregano oil obtained by SFME at 40% power level did not show any inhibitory effect on E. coli O157:H7.

Making a Case for Adaptive Reuse as a Strategy to Revitalize and Generate Urban Tourism in Post-industrial Cities

Judith Ruvuna,Sedef Doganer 세계문화관광학회 2010 Conference Proceedings Vol.11 No.0

The Post Industrial era produced urban environments where what were once vibrant parts of the city became blighted as traditional industries closed. Just over ten years ago, the city of Bilbao was an unknown port in Spain that was on the decline due to the loss of shipping contracts. The city commissioned Frank Gehry to design and build the Guggenheim Museum in Bilbao. The museum became such an iconic structure that the city of Bilbao is now a tourist magnet with millions of visitors every year. In 2000, the architecture firm of Herzog and De Meuron was commissioned to design the museum UK Tate Modern to display the national collection of international modern art. The site selected was an abandoned power plant on the south bank of the river Thames, an area that was neglected. The area is now a vibrant tourist destination. The object of this paper is to investigate how the relationship between architecture, urban tourism and adaptive reuse can play a key role in the revitalization of areas impacted by urban decay. While the idea of using tourism as a vehicle for economic development has been approached in different ways, Judd (1991) focused and developed ideas around the economic role of tourist precincts that had been curved out of urban decay. Based on the findings of this study, a strong case can be made for the concept of adaptive reuse not as a panacea, but as a vehicle for revitalization and growth based on urban tourism.

Coal fly ash (FA) and basic oxygen furnace (BOF) slag are the by-products of coal combustion in power stations and steel plants, respectively. The disposal of these wastes would require landfill space and can cause environmental pollution. In order to avoid disposal, the use of FA and BOF slag as sub-base material in highway pavement was investigated. The first part of this research was the characterization of FA and BOF in terms of their chemical and mineralogical compositions as well as the microstructural analysis. This is followed by the preparation of soil mixtures containing different proportions of kaolin, FA, BOF slag (0%, 15%, 20% and 25% by weight) and lime at a constant ratio (5%). Kaolin was used to represent the natural soil. The soil mixtures were cured for 1, 7 and 28 days and some were cured 56 days. At each curing age, the dry unit weight (dmax), the unconfined compressive strength (UCS) and California bearing ratio (CBR) were determined. X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques were also used to examine the changes in the phase-mineral composition and microstructure properties, respectively. The results show that the maximum dry unit weight values were observed in the mixture consisting of 25% FA, 15% BOF slag and 5% lime. The XRD analyses of kaolin soils containing, FA, BOF slag and lime exhibited the formation of hydrated products such as portlandite (C-H), calcium silicate hydrates (C-S-H) and calcium aluminium silicate hydrate (C-A-S-H), which increase with the age curing. According to results obtained, FA and BOF slag can be used in road base and sub-base materials.

Antioxidative and antiproliferative effects of propolis-reduced silver nanoparticles

Tan, Gamze,Ilk, Sedef,Foto, Fatma Z.,Foto, Egemen,Saglam, Necdet Techno-Press 2021 Advances in nano research Vol.10 No.2

In this study, phytochemicals present in Propolis Extract (PE) were employed as reducing and stabilizing reagents to synthesize silver nanoparticles. Three propolis-reduced silver nanoparticles (P-AgNPs1-3) were synthesized using increasing amounts of PE. P-AgNPs were treated with different cancer cells-lung (A549), cervix (HeLa) and colon (WiDr) - for 24, 48 and 72 h to evaluate their anti-proliferative activities. A non-cancerous cell type (L929) was also used to test whether suppressive effects of P-AgNPs on cancer cell proliferation were due to a general cytotoxic effect. The characterization results showed that the bioactive contents in propolis successfully induced particle formation. As the amount of PE increased, the particle size decreased; however, the size distribution range expanded. The antioxidant capacity of the particles increased with increased propolis amounts. P-AgNP1 exhibited almost equal inhibitory effects across all cancer cell types; however, P-AgNP2 was more effective on HeLa cells. P-AgNPs3 showed greater inhibitory effects in almost all cancer cells compared to other NPs and pure propolis. Consequently, the biological effects of P-AgNPs were highly dependent on PE amount, NP concentration, and cell type. These results suggest that AgNPs synthesized utilizing propolis phytochemicals might serve as anti-cancer agents, providing greater efficacy against cancer cells.

Background: The aim of this study was to assess the epidemiological and clinicopathological characteristics of primary extranodal non-Hodgkin's lymphoma (pENL) patients, focusing on treatment and survival outcome. Materials and Methods: Between October 2003 and March 2012, 802 patients with non-Hodgkin's lymphoma (NHL) were diagnosed and treated in two different cancer centers of Southern Turkey. Results: pENL, constituted 12.4% (100/802) of all NHL studied during this period. Median age of the patients was 56 years (range 17-87 years) and the male: female distribution was 3:2. Eighty-five of 100 patients (85%) were in stage I/II, 9/100 (9%) in stage III, whereas 6/100 (6%) were in stage IV. Head and neck constituted the most common site (51/100, 51%), followed by gastrointestinal tract (GIL) (37/100, 37%), and cerebrum (CL) (5/100, 5%). Diffuse large B cell lymphoma (DLBCL) was the most common histological type, observed in 53% of patients, followed by marginal zone extranodal lymphoma (13%). Most of patients (76%) received a CHOP containing regimen. Complete remission (CR) were achieved in 71% of patients. The median follow-up duration of all patients was reported as 37.6 months (range, 0.8-165 months). This period was reported as 137.5 months (range, 117.5-1578.6 months) in gastrointestinal lymphoma (GIL) patients, 119.0 months (range, 91.8-146.1 months) in head and neck lymphoma (HNL) patients, and 18.4 months (range, 12.6-24.1 months) in cerebral lymphoma (CL) patients. Conclusions: Head and neck, and the gastrointestinal tract were the two most common extranodal sites observed. Histologically DLBC accounted for the majority of cases. Most patients were on earlier stages, had low-low intermediate IPI scores and had a favorable prognosis.

Background: Vitamin D deficiency is a potentially modifiable risk factor that may be targeted for breast cancer (BC) prevention. It may also be related to prognosis after diagnosis and treatment. The aim of our study was to determine the prevalence of vitamin D deficiency as measured by serum 25-hydroxy vitamin D (25-OHD) levels in patients with BC and to evaluate its correlations with life-style and treatments. Materials and Methods: This study included 186 patients with stage 0-III BC treated in our breast center between 2010-2013. The correlation between serum baseline 25-OHD levels and supplement usage, age, menopausal status, diabetes mellitus, usage of bisphosphonates, body-mass index (BMI), season, dressing style, administration of systemic treatments and radiotherapy were investigated. The distribution of serum 25-OHD levels was categorized as deficient (<10ng/ml), insufficient (10-24 ng/ml), and sufficient (25-80 ng/ml). Results: The median age of the patients was 51 years (range: 27-79 years) and 70% of them had deficient/insufficient 25-OHD levels. On univariate analysis, vitamin D deficiency/insufficiency was more common in patients with none or low dose vitamin D supplementation at the baseline, high BMI (${\geq}25$), no bisphosphonate usage, and a conservative dressing style. On multivariate analysis, none or low dose vitamin D supplementation, and decreased sun-exposure due to a conservative dressing style were found as independent factors increasing risk of vitamin D deficiency/insufficiency 28.7 (p=0.002) and 13.4 (p=0.003) fold, respectively. Conclusions: The prevalence of serum 25-OHD deficiency/insufficiency is high in our BC survivors. Vitamin D status should be routinely evaluated for all women, especially those with a conservative dressing style, as part of regular preventive care, and they should take supplemental vitamin D.
