Authors: Abualenain Jameel
Published: December 2024

Effective risk communication is essential for coordinated disaster response, particularly among Emergency Operation Center (EOC) leaders managing crises. This study assesses the perceptions of EOC leaders in Saudi Arabia regarding key risk communication challenges, focusing on clarity, transparency, and consistency. Using a purposive sample of 95 EOC leaders, the study employed a structured survey to gather data on various aspects of disaster communication. Results indicated high ratings for the clarity and accessibility of information, though transparency and consistency scored lower, revealing gaps in cross-agency communication. Notable correlations between trust, reliability, and transparency suggest that strengthening one element may reinforce others, promoting cohesive disaster response.
Qualitative responses highlighted the need for standardized protocols, real-time updates, and culturally adaptive messaging suited to the regional context. The findings emphasize practical steps, including centralized communication channels, designated spokespersons, and training programs tailored to EOC leaders’ unique needs. These measures, emphasizing clarity, consistency, and trust, can improve inter-agency coordination and strengthen disaster resilience. This study contributes to the literature on disaster management by providing insights into the Saudi Arabian context, with implications for policy and practice in risk communication.

Published: December 2024

Purpose: To evaluate degree of insight, accessibility to medical care, and availability of regular ocular screening examinations before diagnosis for Korean patients with wet age-related macular degeneration.Methods: Data were collected from 95 patients by questionnaire and analyzed at Seoul National University Boramae Medical Center.Results: Although 80.0% of the patients considered themselves old, only 2.1% thought they were susceptible to wet age-related macular degeneration. Of the overall patients, 48.4% thought their disease was serious despite treatment with intravitreal injections. A majority (71.6%) thought that medical care was easily accessible, 67.4% answered that hospitals were located close by, and 90.5% answered that it was easy to make appointments and they had time to visit the hospital. However, only 15.8% answered that they had undergone regular ocular examinations before being diagnosed with wet age-related macular degeneration.Conclusions: Although most patients believed that they had easy access to medical care, only 15.8% underwent regular ocular examinations. Therefore, regular ocular examinations, including fundal examinations, are required in national health screening programs. It is also important to raise public awareness of wet age-related macular degeneration by educating the general population.
Comparison of Physical Properties of Polypropylene Sutures and Knot Method to Prevent the Slippage of Sutured Scleral Fixation
Authors: Choi Yeon Hee , Kang Min Ho
Published: December 2024

Purpose: This study compared the physical properties of 9-0 and 10-0 polypropylene sutures used in scleral-sutured posterior chamber intraocular lens (PCIOL) fixation, with a focus on knot security and methods to prevent slippage.Methods: Tensile strength measurements were performed on 10-0 and 9-0 polypropylene sutures (Prolene™) using a material testing machine (Instron 5966 Load Frame, Model 2701-065 controller; Instron Corp., Norwood, MA). Various knotting techniques were evaluated, including a single fisherman’s knot and one, three, and five overhand knots tied around the haptic of a three-piece IOL. Knot thickness and area of the surgeon’s Knot were measured using microscopy and Image J® software, with statistical analysis conducted to compare the differences between the two suture types.Results: The 9-0 polypropylene sutures exhibited a significantly higher maximum tensile strength than the 10-0 sutures, particularly with a single fisherman’s knot (0.47 N vs. 0.52 N, p = 0.007; 0.27 N vs. 0.50 N, p < 0.001). However, when multiple overhand knots were tied around the haptic, the 10-0 sutures showed increased tensile strength with more knots (0.11 N, 0.23 N, 0.33 N, p < 0.05), whereas the 9-0 sutures did not (0.06 N, 0.31 N, 0.19 N). Notably, three overhand knots provided better stability than five knots (p < 0.05). The knot area and thickness of the surgeon’s knot were significantly larger in the 9-0 sutures than in the 10-0 sutures (21,062.4 μm2 vs. 41,188.5 μm2, p < 0.001; 160.1 μm vs. 195.6 μm, p = 0.021).Conclusions: Overhand knots increased friction between the suture and IOL haptic, enhancing knot security. However, in the 9-0 sutures, the higher rigidity caused the knots to loosen more easily, decreasing the tensile strength with more knots. This study suggests that three overhand knots are optimal for securing IOL haptics using both 9-0 and 10-0 sutures.

Bu bağlamda çalışmanın amacı, yeşil tedarik zinciri yönetimi ve çevresel performans arasındaki ilişkide yeşil inovasyonun aracılık rolü üstlenip üstlenmediğini ortaya koymaktır. Araştırmada tanımlayıcı istatistikler, açımlayıcı faktör analizi, normallik testi, korelasyon analizi, regresyon analizi ve aracılık etkisini test etmek için ise Baron ve Kenny (1986)'nin yaklaşımı kullanılmıştır. Araştırma bulgularına göre, yeşil tedarik zinciri yönetiminin çevresel performansı ve yeşil inovasyonu anlamlı ve pozitif yönde etkilediği tespit edilmiştir. Yeşil inovasyonun çevresel performansı pozitif ve anlamlı şekilde etkilediği saptanmıştır. Yeşil tedarik zinciri yönetiminin çevresel performans üzerindeki etkisinde yeşil inovasyonun kısmi aracılık etkisi olduğu görülmüştür. Yeşil tedarik zinciri yönetimi uygulamalarını benimseyen ve yeşil inovasyon performansını artırmak için çabalayan işletmelerin çevresel sürdürülebilirlik hedeflerine ulaşmaları daha olası hale gelebilecektir. Bununla birlikte işletmenin çevresel etkilerini azaltmalarına katkı sağlayabilir. Bu süreç, işletmelerin rekabet avantajı elde etmelerine, maliyet tasarrufları yapmalarına ve sürdürülebilir iş modelleri oluşturmalarına olanak tanıyacaktır.

Kırsal peyzajlar günümüz kent peyzajlarının beslendiği kaynaklar olmakla birlikte, sahip oldukları doğal ve kültürel değerlerle koruma, yönetim ve planlama faaliyetlerinin de merkezî konumundaki peyzajlardır. Türkiye’nin doğal ve kültürel peyzajları içerisinde de şüphesiz öne çıkan yerlerden ilki; UNESCO Dünya Miras Listesinde de yer alan Kapadokya’nın sahip olduğu eşsiz peyzajlar ve sahip olduğu değerlerdir. Bu araştırmada, Nevşehir’in Ürgüp ilçesine bağlı Cemil, Taşkınpaşa ve Şahinefendi köylerinin kırsal yerleşim tipolojileri ve peyzaj özellikleri, yerinde gözlem ve sayısal yükseklik modeli verileri kullanılarak incelenmiştir. Çalışma kapsamında Cemil, Taşkınpaşa ve Şahinefendi köylerinin doğal topoğrafyası, kültürel değerleri ve kaya oyma yapıları ile şekillenen kırsal peyzaj karakteri incelenmiştir. Çalışmada, kırsal miras-peyzaj ilişkisi temelinde, doğal tüf ve kayalık yapı üzerinde farklı medeniyet ve toplumların binlerce yılda yoğurup geliştirdiği doğal ve kültürel yapının bugün barındırdığı değerler ortaya konarak, geleneksel yapı tekniklerinin bu köylerin kültürel ve mimari kimliğini nasıl şekillendirdiği ele alınmaktadır. Köylerin peyzaj yapısı, bölgenin doğal topoğrafyası, kültürel değerleri ve geleneksel yapı teknikleri ile şekillenmiş bir bütünlüğü yansıtmaktadır. Kırsal yerleşmeler, tarihi süreç boyunca doğal unsurlarla uyum içinde gelişmiş, tarımsal faaliyetler, su kaynakları ve yerel kültürel miras unsurları ile şekillenmiştir. Doğal ve kültürel unsurların sürdürülebilir uygulamalarla korunmasının önemi vurgulanarak, bölgenin mimari bütünlüğünü ve kırsal karakterini korumak için öneri ve değerlendirmelerde bulunulmuştur.

Kimyasal gübre kullanımı toprağın yapısını bozduğu ve sürdürülebilir bitki gelişimini olumsuz etkilediği için günümüzde kimyasal gübre kullanımına alternatif olarak organik gübre kullanımı önem kazanmıştır. Çalışmamızda sıvı yosun gübresi ve vermikompost gübresi kullanılarak arpa gelişimi ve kök bölgesi mikrobiyolojik özelliklerine etkisi incelenmiştir. Deneme serada tesadüf parselleri deneme desenine göre 3 tekrarlı olarak yürütülmüştür. Vermikompostun 4 dozu (kontrol, % 10, % 20 ve % 40), sıvı yosun gübresinin 4 dozu (kontrol, % 1, % 2 ve % 3) ve vermikompost ile sıvı yosun gübresinin kombinasyonu ayrı ayrı topraklara uygulanmıştır. Tohum ekiminden 60 gün sonra bitkiler hasat edilmiştir. Uygulamalar yeşil aksam ve kök ağırlığını, bitki boyu ve kök uzunluğunu artırmıştır. Yaprakların klorofil içerikleri vermikompost ve sıvı yosun gübresi uygulaması ile kontrole göre artmıştır. Vermikompostun ve sıvı yosun gübresinin artan dozları rizosferdeki mikrobiyal solunum ve β-glukosidaz aktiviteyi kontrole göre önemli ölçüde artırmış, en yüksek artış vermikompost %40 ile yosun gübresinin %3’lük interaksiyonunda elde edilmiştir.
An Overview Diagnosis and Treatment Methods in Cases of Transmissible Venereal Tumor in Female Dogs
Authors: Saat Nevzat , Çetinkaya Yusuf Bilal
Published: December 2024

The aim of this review is to examine an overview diagnostic and treatment methods applied in cases of transmissible venereal tumors (TVT) in female dogs. TVT is a highly transmissible neoplasm affecting dogs of all ages, breeds, and genders, primarily involving the genital areas and organs such as the eyes, nose, and mouth. Various clinical manifestations are observed depending on its localization. In cases involving the genital system, cauliflower-like neoplastic masses, bloody vulvar discharge, and consequent anemia may occur. All these clinical findings, along with histopathological or cytological examinations of tissue samples obtained through methods such as excisional biopsy or fine needle aspiration biopsy, can lead to a definitive diagnosis. Once a definitive diagnosis is made, various treatment options are available, including surgical excision of tumor tissue, chemotherapy using agents such as vincristine, doxorubicin, cyclophosphamide, methotrexate, and lomustine, radiotherapy with specific dose ranges, and immunotherapy using agents like Bacillus Calmette-Guérin and staphylococcal protein A. In conclusion, with the correct diagnosis, every patient can be individually evaluated and provided with the most appropriate treatment option to ensure recovery.

Published: December 2024

The aim of this study was to investigate the parietal and temporal regions of the brain stereologically after epilepsy induced by pentylenetetrazole (PTZ). 20 healthy male Wistar Albino rats, 3 months old, weighing approximately 250 gr, were chosen for the study. The rats were divided into PTZ and control groups, 10 in each group. 80 mg/kg PTZ was mixed into 0.5 ml of 0.9% physiological saline and administered intraperitoneally as a single dose injection to the PTZ group. Behavioral changes specified in six stages were determined by following the Racine scale within a 30-minute observation period. After perfusion, the rats’ brains were removed. After tissue tracking, an average of 10 sections were obtained for each animal, with a thickness of 1/75 of 5µm. Sections were stained with Hematoxylin-Eosin. The preparations were photographed with a 1.25 objective. For each brain tissue, the total lobus parietalis, lobus temporalis, the grey matter volume and the total number of neurons in the lobus parietalis and lobus temporalis were calculated. Mann-Whitney U test was used for statistical analysis (IBM SPSS for Windows, ver.25) No statistically significant difference could be detected in the total lobus parietalis, lobus temporalis and the grey matter volume, volume values of the brain and the number of neurons determined between the groups (p>0.05). However, when evaluated according to groups, a significant difference was obtained in the volume ratio values, the grey matter volume/total lobus parietalis and the grey matter volume/total lobus temporalis ratio (p<0.05).

This work investigated food security status among vegetable women producers in North West, Nigeria. Primary data were used based on a well-organized questionnaire. The data were evaluated using descriptive statistics, Tobit regression model, food security index, and principal component model. The outcome shows that averagely the age, household size, and farm size approximates 48 years, 9, and 0.75 ha respectively. A household is regarded as food secure if it achieves at least 2/3 of the MPCFE (Mean per Capital Consumption Food Expenditure) per month. Therefore, the vegetable women producers that spent at least N 2,125.51 (1USD =N 1,040) on food per month were grouped as food secure, and those that spent less than this figure were grouped as food insecure. This denotes that the vegetable women producer to be regarded as food secure will spend above N 70.85 on food per day. Based on the headcount ratio, about 54% of vegetable women producers had their per capital food expenditure equal or above N 2,125.51, while 46% of them had their per capital food expenditure below N 2,125.51. The educational level, age, household size, income from vegetable farming off farm income and access to credit were different significantly from zero in deciding the food security status of vegetable women producers. The major challenges faced by vegetable women producers include lack of improved seeds (1st), lack of credit (2nd), and lack of access to land (3rd). Credit should be made available at single digit interest rate to enhance productivity, and increase food security
