Belediyelerin karar organları seçim yoluyla oluşturulur. Sosyal politikaları yerel düzeyde başarıyla yürüten belediyeler literatürde genellikle "sosyal belediyecilik" kavramıyla araştırılmaktadır. Sosyal belediyecilik odaklı belediyeler, toplulukların barınma, eğitim, sağlık, yoksulluk, işsizlik ve çevre ile ilgili sorunlarını yönetmek ve ortadan kaldırmak için çeşitli sosyal hizmetler ve programlar sunmaktadır. Sosyal belediyeciliği uygulamaya alan belediye idareleri kadınlar, çocuklar, gençler, yaşlılar ve engellilerden oluşan dezavantajlı guruplara özellikle daha fazla önem vermektedirler. Türkiye'de son zamanlarda sosyal belediyecilik alanında önemli gelişmeler gözlenebilmektedir. Dolayısıyla bu çalışmanın temel amaçlarından biri sosyal belediyeciliği...

Materyal ve Metot: Çalışma kapalı yetiştirme sisteminde üç farklı yerleşim sıklığında (m 2 'de 6.6, m 2 'de 9.3, m 2 'de 12 beç tavuğu) yetiştirilen toplamda 252 beç tavuğu ile yürütülmüştür. Günlük yaşta, 2, 4, 6, 8, 10, 12 ve 13. haftalarda canlı ağırlık, yem tüketimi ve yemden yararlanma oranı belirlenmiştir. Kesim ve karkas özellikleri 13. haftada tespit edilmiştir. Bulgular: Çalışmada 6. hafta ve sonrasında yüksek yerleşim sıklığına sahip grupta daha düşük canlı ağırlık tespit edilmiştir. Kümülatif yem tüketimi 4. haftadan sonra düşük yerleşim sıklığında yetiştirilen beç tavuklarında daha yüksek bulunmuştur. Bununla birlikte yemden yaralanma oranı ise 6. hafta ve sonrasında düşük yerleşim sıklığı grubunda daha yüksek belirlenmiştir. Kesim ve karkas ağırlıkları ve oranları üzerine ise yerleşim sıklığının önemli bir etkisi tespit edilmemiştir. Sonuç: Yerleşim sıklığının 13 haftalık kesim yaşındaki beç tavuklarında canlı ağırlık, yem tüketimi, yemden yararlanma oranı ve ölüm oranı üzerine önemli etkisi olduğu, kesim ve karkas özelliklerini ise etkilemediği belirlenmiştir. Büyüme performansı ve üretim maliyetleri bakımından en ekonomik yetiştiriciliğin birim alanda 9-10 beç tavuğu ile sağlanabileceği söylenebilir. Ancak beç tavuğu gibi alternatif kanatlı türleri için doğal yaşam alanlarından çok farklı olan kapalı sistemlerde yetiştirmenin refah durumu ve doğal davranış özelliklerine etkilerini ortaya koyan ileri çalışmalara ihtiyaç duyulmaktadır.

Dünya Sağlık Örgütü'nün 2013 yıllık raporuna göre, dünya nüfusunun yarıdan fazlası ve Türkiye nüfusunun %90'dan fazlası kentlerde yaşamaktadır. Kentlerin artan nüfus yoğunluğu ile birlikte çeşitli alanlarda hizmet gereksinimleri de artmakta ve çeşitlenmektedir. Artan bu hizmet çeşidi ve gereksinimleri için kentlerin yönetilmesinden sorumlu yerel yönetimlerin etkin çözümler bulması için birtakım yeni arayışlara girdikleri görülmektedir. Bunlar arasında, AB kentlerinde uygulaması yaygınlaşmış, ancak Türkiye'de bir süredir uygulanmaya başlanan akıllı kent projeleri bulunmaktadır. Bu kapsamda, yerel yönetimler artan ve çeşitlenen hizmet beklentilerini ve yaşlanan altyapının dönüşümünü sağlayabilmek adına kentlerdeki verileri daha iyi analiz etmek, sorunları daha kolay tahmin etmek ve kaynakları iyi koordine etmek için söz konusu akıllı kent projelerini geliştirme gereksinimi duymaktadır. Bu çalışmada, öncelikle akıllı kent kavramı ve bu konudaki Avrupa Birliği politika ve uygulamalarından bahsedilecek, ardından Türkiye'de bu konuda yapılan çalışmalar açıklanacak, son olarak ise akıllı kent uygulamalarının kentlerin sürdürülebilirliğine katkıları değerlendirilecektir.

The effect of breeder flock age, storage temperature and a short period of incubation during egg storage (SPIDES) on albumen quality, development of blastoderm, and hatchability of long-stored eggs was evaluated. 2. Hatching eggs were collected from 28-week-old (young) and 40-week-old (prime) Ross female line grandparent flocks and were stored for 14 d at 12, 15 or 18°C. During storage, the eggs were either kept continuously in the storage room (control) or were subjected to SPIDES treatment. 3. Embryonic development was more advanced in eggs from the prime flock, exposed to SPIDES and warmer (18°C) storage temperature (P ≤ 0.05). There was a difference in the albumen pH for flock ages (P < 0.05), but the SPIDES treatment did not affect albumen height and pH (P > 0.05). On d 14 of storage, albumen pH was positively (P < 0.05) correlated with storage temperature. Hatchability was higher in the prime flock (P < 0.05). 4. At both flock ages, hatchability increased (P < 0.05) by storing the eggs at 15°C, compared to 18°C, with 12°C intermediate. The hatchability improvement was due to reduced early embryonic mortality. 5. The SPIDES treatment decreased late embryonic mortality and the percentage of second-grade chicks (P < 0.05), which increased the hatchability of fertile eggs (P < 0.05). SPIDES only reduced (P < 0.05) early embryonic mortality in eggs stored at 18°C. 6. The highest hatchability was observed in the eggs stored at 15°C and exposed to one SPIDES treatment during 14 d storage.

The aim of this study is to investigate the effects of genotype (Pharaoh and Italian) and egg weight (heavy and light) on egg weight loss and hatching results during the embryo development of hatching eggs obtained from quails. In this study, a total of 754 eggs obtained from Pharaoh and Italian quail flocks reared under the same environmental conditions and 1 male:3 female ratio were used. Eggs are divided into two groups according to the average egg weight of both genotype. The study was arranged according to the factorial experimental design (2 genotypes × 2 weight groups × 3 replicates). The average weight loss was 13.12% and 10.83% in Pharaoh and Italian breeds, respectively, and were statistically different. The average weight loss according to the heavy and light e...

Tissue pH is a key physiological parameter and herein, we report the design, fabrication, functionalisation, encapsulation and protection of a miniaturised, self-contained, electrochemical pH sensor system and characterisation of sensor performance. Notably for the first time in this environment the pH sensor was based on a methylene blue redox reporter which showed remarkable robustness, accuracy and sensitivity. This was achieved by encapsulation of a self-assembled monolayer containing methylene blue entrapped within a Nafion layer. Another powerful feature was the incorporation, within the same implanted device, of a fabricated on-chip Ag/AgCl reference electrode - vital in any electrochemical sensor, but often ignored. When utilised in vivo, the sensor allowed accurate tracking of externally induced pH changes within a naturally occurring ovine lung cancer model, and correlated well with single point laboratory measurements made on extracted arterial blood, whilst enabling in vivo time-dependent measurements. The sensors functioned robustly whilst implanted, and maintained in vitro function once extracted and together, these results demonstrate proof-of-concept of the ability to sense real-time intratumoral tissue pH changes in vivo.

Color, pH, cooking loss, water holding capacity and drip loss were determined as meat quality traits. Production system did not have significant effect on most of meat quality traits. Conversely, most of these traits were affected by slaughter age. Water holding capacity significantly decreased but cooking loss increased by slaughter age. Total digestive system weight rate to body weight was decreased by slaughter age but did not differ between production systems. Small and large intestine lengths were significantly longer in indoor system and significantly decreased by slaughter age.

Production system had a significant effect on live weight until 14 wk of age. Live weights were similar between free‐range and indoor production systems at 16 (1,150 g vs. 1,152 g) and 18 (1,196 g vs. 1,203 g) wk of age. Guinea fowl reared in a free‐range system consumed more feed (7,693 g vs. 6,983 g), and guinea fowl reared in a barn had better feed conversion ratio (5.80 vs. 6.43) (P < 0.05). Production system, gender, and slaughter age did not affect the dressing percentage. Guinea fowl reared in a free‐range system had significantly less abdominal fat (P < 0.05).

The effect of breeder flock age, storage temperature and a short period of incubation during egg storage (SPIDES) on albumen quality, development of blastoderm, and hatchability of long-stored eggs was evaluated. 2. Hatching eggs were collected from 28-week-old (young) and 40-week-old (prime) Ross female line grandparent flocks and were stored for 14 d at 12, 15 or 18°C. During storage, the eggs were either kept continuously in the storage room (control) or were subjected to SPIDES treatment. 3. Embryonic development was more advanced in eggs from the prime flock, exposed to SPIDES and warmer (18°C) storage temperature (P ≤ 0.05). There was a difference in the albumen pH for flock ages (P < 0.05), but the SPIDES treatment did not affect albumen height and pH (P > 0.05). On d 14 of storage, albumen pH was positively (P < 0.05) correlated with storage temperature. Hatchability was higher in the prime flock (P < 0.05). 4. At both flock ages, hatchability increased (P < 0.05) by storing the eggs at 15°C, compared to 18°C, with 12°C intermediate. The hatchability improvement was due to reduced early embryonic mortality. 5. The SPIDES treatment decreased late embryonic mortality and the percentage of second-grade chicks (P < 0.05), which increased the hatchability of fertile eggs (P < 0.05). SPIDES only reduced (P < 0.05) early embryonic mortality in eggs stored at 18°C. 6. The highest hatchability was observed in the eggs stored at 15°C and exposed to one SPIDES treatment during 14 d storage.

Aim: This study aimed to compare serum SPX levels in obese adolescents versus healthy controls and to assess the associations of metabolic syndrome (metS) antecedents with serum SPX levels. Methods: Eighty consecutive obese adolescents aged 10–18 years and 80 healthy peers were enrolled. Anthropometric measurements, pubertal examinations, and clinical blood pressure measurements were performed. Fasting blood samples were drawn for glucose, insulin, lipids, uric acid, alanine aminotransferase (ALT), and SPX. metS was diagnosed using International Diabetes Federation criteria. Associations of serum SPX with clinical and laboratory variables were assessed. Results: Obese adolescents had lower serum SPX levels than healthy peers (50 pg/mL [25–75% IQR: 25–98 pg/mL] and 67.0 pg/mL [25–75% IQR: 32.5–126.0 pg/mL]; respectively, p = 0.035). Twenty (25%) obese adolescent...

The research was designed as a descriptive case study within the framework of qualitative research methods. Two criteria that the participants to be included in the study should have were determined as follows: graduating from universities’ hearing-impaired teaching programs and serving as a special education classroom teacher in schools affiliated to the MNE. The participants consist of 51 teachers meeting the specified criteria. Semi-structured interviews were held with 5 of the participants, and data were collected from 46 of them through an open-ended questionnaire. Given the pandemic period conditions we currently experience, the e-interviews were conducted using Zoom, while open-ended questionnaires were collected via Google Forms. Descriptive analysis technique was used in the analysis of the research data. The descriptive analysis p...

Tissue pH is a key physiological parameter and herein, we report the design, fabrication, functionalisation, encapsulation and protection of a miniaturised, self-contained, electrochemical pH sensor system and characterisation of sensor performance. Notably for the first time in this environment the pH sensor was based on a methylene blue redox reporter which showed remarkable robustness, accuracy and sensitivity. This was achieved by encapsulation of a self-assembled monolayer containing methylene blue entrapped within a Nafion layer. Another powerful feature was the incorporation, within the same implanted device, of a fabricated on-chip Ag/AgCl reference electrode - vital in any electrochemical sensor, but often ignored. When utilised in vivo, the sensor allowed accurate tracking of externally induced pH changes within a naturally occurring ovine lung cancer model, and correlated well with single point laboratory measurements made on extracted arterial blood, whilst enabling in vivo time-dependent measurements. The sensors functioned robustly whilst implanted, and maintained in vitro function once extracted and together, these results demonstrate proof-of-concept of the ability to sense real-time intratumoral tissue pH changes in vivo.

Color, pH, cooking loss, water holding capacity and drip loss were determined as meat quality traits. Production system did not have significant effect on most of meat quality traits. Conversely, most of these traits were affected by slaughter age. Water holding capacity significantly decreased but cooking loss increased by slaughter age. Total digestive system weight rate to body weight was decreased by slaughter age but did not differ between production systems. Small and large intestine lengths were significantly longer in indoor system and significantly decreased by slaughter age.

Hatching eggs were collected from commercial flocks of Ross 308 breeders at 35 and 39 wk of age in experiments 1 and 2, respectively. Chicks already out of their shells that still had some dampness on their down were removed, recorded, feather-sexed, and weighed at 488 h of incubation in both experiments. Chicks were weighed individually and received feed and water at 2 (immediate feed;

Production system had a significant effect on live weight until 14 wk of age. Live weights were similar between free‐range and indoor production systems at 16 (1,150 g vs. 1,152 g) and 18 (1,196 g vs. 1,203 g) wk of age. Guinea fowl reared in a free‐range system consumed more feed (7,693 g vs. 6,983 g), and guinea fowl reared in a barn had better feed conversion ratio (5.80 vs. 6.43) (P < 0.05). Production system, gender, and slaughter age did not affect the dressing percentage. Guinea fowl reared in a free‐range system had significantly less abdominal fat (P < 0.05).
