Authors: TAŞÇIOĞLU Saliha
Published: January 2023

Amaç: Kilis ve Trabzon Kentsel Sit Alanında yer alan toplam 10 farklı yapı örneğine ait konut bahçesinin özellikleri ele alınarak, karşılaştırmalar yapılmış ve incelenmiştir. Avlu-bahçe biçimlenmesi, karakteristik özellikleri analiz edilmiştir. Bu incelemeler sonucunda yıllar içerisinde farklı etkilerle şekillenmiş olan konut bahçelerinin benzerlik ve farklılıklarının tespiti hedeflenmiştir.

Materyal ve Yöntem: Çalışmanın materyalini Kilis Kentsel Sit Alanı ile Trabzon 1 ve 2 Nolu Kentsel Sit Alanı oluşturmaktadır. Kentsel Sit Alanları içerisinde her bir kent için 5’er adet olmak üzere toplam 10 adet Sivil mimarlık örneği belirlenmiştir. Belirlenen örnekler bahçe yapısı olarak irdelenmiş ve özellikleri belirlenmeye çalışılmıştır. Her bir örnek için formlar oluşturulmuş ve karşılaştırma yapılmıştır.

Araştırma Bulguları: Kilis kenti için elde edilen bulgularda sert zemin kaplı avlu alanlarının daha baskın olduğu, avlu içerisinde havuz veya yeşil alanların sert zemin içerisinden ayrılarak belirlendiği tespit edilmiştir. Trabzon kenti için elde edilen bulgularda ise konut alanlarına ait yeşil alanların daha baskın olduğu belirlenmiştir. Kullanılan bitki türleri incelendiğinde Trabzon’da 35 farklı bitki türü, Kilis’te ise 6 farklı bitki türü tespit edilmiştir.

Sonuç: Seçilen kent örneklerinin incelenmesi sonucunda, farklılıkların yanı sıra ortak özelliklerin de olduğu belirlenmiştir. Avlu-bahçe kullanımının günlük yaşamda önemli bir yerinin olduğu, iklimsel etkiler nedeniyle Kilis’te daha yoğun kullanımının olduğu söylenebilir. Trabzon’da bazı konut bahçelerinde yeşil alanların sert zemine dönüştüğü görülürken, Kilis’te ise bu durum geçerli değildir. Bitkisel kullanım anlamında ise Kilis’te sarılıcı ve tırmanıcı türlerin, Trabzon’da ise ağaç-ağaççık türlerinin daha yoğun kullanıldığı tespit edilmiştir.

Published: January 2023

Amaç: Bu çalışma, tohum dormansisi görülen düğmeli yonca hatlarında dormansiyi kırmak için farklı uygulamaların çimlenme ve fide gelişim özellikleri üzerine etkisinin belirlenmesi amacıyla yürütülmüştür.
Materyal ve Yöntem: Bu denemede; kontrol, zımparalama (1, 2 ve 3 dakika), 25°C oda sıcaklığı koşullarındaki suda bekletme (6, 24 ve 48 saat), 70°C sıcak suda bekletme (5, 15 ve 20 dakika), dondurucu ve ardından buzdolabında bekletme (2saat-5 gün ve 4 saat-10 gün), kum+demir talaşı karışımı ile tahrip etme (1, 2 ve 3 dakika), sülfürik asit (%70) çözeltisinde bekletme (30, 50 ve 70 dakika), zımparalama (1 dakika) ve ardından sodyum hipokloritte bekletme (4, 8 ve 10 dakika) yöntemleri kullanılmıştır. Deneme tesadüf parsellerinde bölünmüş parseller deneme desenine göre 3 tekerrürlü olarak laboratuvar ortamında yürütülmüştür. Deneme planında ana parselleri hatlar, alt parselleri uygulamalar oluşturmuştur.
Araştırma Bulguları: Denemenin genelinde, zımparalama (2 dakika) ve zımparalama (1 dakika) + sodyum hipokloritte bekletme (4 dakika) yöntemleri etkili bulunmuştur. Tohum kabuğuna fiziksel veya kimyasal yollarla hasar vermek, çimlenmeyi kolaylaştırıcı bir etki sağlamıştır. Hatlar ve uygulamalar genel olarak kontrole göre daha iyi sonuçlar vermiştir.
Sonuç: Düğmeli yonca (Medicago orbicularis (L.) Bart.) tohumlarının sert kabukluluk özelliği, zamanla azalmaktadır. Ancak bu çalışmada ele alınan fiziksel ve kimyasal uygulamalar, tohumun dormansi evresinde çimlenebilmesini sağlamıştır. Uygulamaların türü ve süresi, bu değişken yapılı tohum kabuklarında, ancak optimum oranda hasar bırakırsa, tohum çimlendikten sonra gelişimine devam edebilir. Bu da hatlar ve uygulamalar açısından da değişken olmuştur. Hatlar uygulamalara farklı tepkiler gösterdiğinden, çalışılan tür, çeşit veya hattın dormansi durumu iyi bilinmelidir. Bu tohumların kaç yıl önce toplandığı, ne kadar süre depo edildiği, hangi ortam şartlarında bekletildiği de önemlidir. Bunların yanında çeşitli biyokimyasal testlerin, çalışmadan önce ve sonra yapılmış olması, bu test sonuçlarının değerlendirilmesi, en doğru yöntemi bulmakta fayda sağlayacağı sonucuna varılmıştır.

Published: January 2023

Our objective was to study the activity of Ludwigia octovalvis hydro alcoholic extract in rats made experimentally hypertensive by a hypersodic diet. After 21 days of this diet, the systolic and diastolic blood pressure of these animals increases to 200.1 ± 1.5 / 155.6 ± 1.5 mm Hg, respectively. Administered orally, the extract reduces this high blood pressure. The control group blood pressure returned to its normal value (113.2 ± 1.2/76.3 ± 1) mm Hg after 24 days, versus 9th, 15th and 19th days for animals treated with the extract at doses of 400, 200 and 100 mg / kg (P <0.05). It does not have any diuretic activity but relaxes the isolated aorta contracted with norepinephrine 10-4 M with an EC50 equal to 1.18 ± 0.02 mg/ml. These results indicate that Ludwigia octovalvis extract has an antihypertensive activity by its vasodilator property. The polyphenols, triterpenoids and flavonoids in the extract may be responsible for its hypotensive activity.

Published: January 2023

Objectives This study aimed to assess the efficacy and safety of manual therapy in patients with failed back surgery syndrome (FBSS). Methods We searched eight electronic databases from October 2022 and only selected randomized controlled trials (RCTs) reporting outcomes for manual therapy in FBSS patients. Included studies were analyzed qualitatively. Results A total of twelve RCTs were included and three studies were meta-analyzed. Manual therapy combined with exercise demonstrated more favorable outcomes in terms of pain reduction compared to exercise therapy only (P<0.01). Some studies reported that manual therapy resulted in low efficacy, while some studies reported that specific manual techniques have a significant effect in pain relief. We, therefore, conclude that several studies have a high risk of bias. Conclusions Findings suggest that manual therapy is a safe and non-invasive, promising option for managing FBSS. However, manual therapy is not the best option in all circumstances; thus, this should be selectively applied by a well-trained practitioner. Further studies such as well-designed, risk-controlled RCTs are required to gain stronger evidence.

CPM (Critical Path Method) dan PERT (Project Evaluation and Review Technique) merupakan teknik dalam matematika yang menggunakan prinsip jaringan untuk memprediksi durasi pelaksanaan sebuah proyek. Melalui kedua metode ini akan ditentukan kegiatan-kegiatan kritis yang dapat mempengaruhi ketepatan maupun keterlambatan dari penyelesaian suatu proyek. Penelitian ini berfokus pada pemberian uraian tentang konkretisasi CPM dan PERT dalam upaya memprediksi durasi dan biaya pembangunan Musala Al-Ikhlas yang terletak di Kotawaringin Barat, Kalimantan Tengah. Penelitian ini mengusung jenis penelitian deskriptif kuantitatif. Teknik wawancara dan telaah dokumen dilakukan untuk memperoleh data berupa jenis kegiatan, durasi setiap kegiatan, biaya pembangunan, serta SDM yang terlibat. Data yang terhimpun kemudian dianalisis dengan menggunakan CPM dan PERT. Hasil penelitian menunjukkan bahwa implementasi CPM dan PERT dapat memprediksi durasi proyek pembangunan musala yang lebih singkat dari prediksi awal. Durasi pembangunan yang lebih singkat memberikan dampak berupa berkurangnya biaya pembangunan musala, khususnya pada biaya untuk tenaga kerja.
CPM (Critical Path Method) and PERT (Project Evaluation and Review Technique) are methods in mathematics that use network principles to predict the duration of a project's implementation. Through these two methods, critical activities will be determined that can affect the accuracy or delay of the completion of a project. The focus of this study to provide an overview of the implementation of CPM and PERT in an effort to predict the duration and cost of building the Al-Ikhlas Mosque located in West Kotawaringin, Central Kalimantan. This research carries the type of descriptive research with a quantitative approach. Interview techniques and document review were carried out to obtain data in the form of types of activities, duration of each activity, development costs, and the human resources involved. The collected data was then analyzed using CPM and PERT. The results showed that the implementation of CPM and PERT can predict the duration of the mosque construction project which is shorter than the initial prediction. The shorter duration of construction has the effect of reducing the cost of building a prayer room, especially the cost for labor.

Introducción. La diabetes mellitus tipo 2 y la obesidad son enfermedades con alta prevalencia, gran morbimortalidad y elevados costos en salud. La cirugía bariátrica ha demostrado efectividad para inducir pérdida de peso y un control adecuado de la glicemia.
Métodos. Estudio observacional analítico retrospectivo, realizado entre 2014 y 2019 en una institución de alta complejidad. Se incluyeron pacientes prediabéticos y diabéticos sometidos a cirugía bariátrica tipo baipás gástrico en Y-de-Roux o manga gástrica. Se analizaron la mejoría o resolución de la diabetes y la pérdida del exceso de peso a los 6, 12, 24 y 36 meses luego de la cirugía.
Resultados. Se incluyeron 103 pacientes en el estudio, 45 pacientes diabéticos y 58 pacientes prediabéticos. La única variable perioperatoria con diferencia estadísticamente significativa fue el tiempo quirúrgico mayor en el baipás (70 vs. 47,5 minutos; p<0,001). La pérdida de exceso de peso fue mayor en el baipás. Los pacientes diabéticos sometidos a baipás tuvieron un mayor porcentaje de resolución o control comparados con los sometidos a manga gástrica. En los pacientes prediabéticos hubo resolución en ambos grupos luego de 24 meses de seguimiento.
Conclusión. El baipás gástrico y la manga gástrica presentan excelentes resultados en cuanto a pérdida de peso y control metabólico en pacientes con diabetes mellitus tipo 2 y prediabetes, pero en nuestros pacientes se lograron resultados superiores en ambos aspectos con el baipás gástrico.

Introducción. La cirugía bariátrica es efectiva para inducir una rápida pérdida del exceso de peso, pero existen dudas sobre la duración de este efecto a largo plazo. Este estudio buscaba identificar la proporción de pacientes operados que presentaron una pérdida insuficiente o una ganancia significativa de peso y los posibles factores relacionados.
Métodos. Estudio de cohorte retrospectivo en pacientes adultos sometidos a cirugía bariátrica. Se describieron variables demográficas y clínicas. Se realizó un análisis multivariado para identificar factores relacionados con un peso fuera de metas posterior a la cirugía.
Resultados. Se incluyeron 187 pacientes, 117 con baipás gástrico y 70 con manga gástrica. La mediana de índice de masa corporal preoperatorio fue 41,3 kg/m2 y postoperatorio de 28,8 kg/m2. El 94,7 % de los pacientes en ambos grupos logró una adecuada pérdida del exceso de peso. La ganancia de peso mayor del 20 % se presentó en el 43,5 % de los pacientes, siendo mayor en el grupo de manga gástrica (p<0,004). Los factores independientes para ganancia de peso fueron el sexo masculino (OR 5,5), cirugía tipo manga gástrica (OR 3,4), síndrome de apnea del sueño (OR 2,9) y enfermedad mental medicada (OR 2,8).
Conclusión. La cirugía bariátrica produce una pérdida del exceso de peso suficiente en casi la totalidad de los pacientes, pero un buen número recuperan peso luego de 3 años. Los principales factores asociados a ganancia de peso son el sexo masculino y la cirugía tipo manga gástrica.
