Mydriasis induced hyphema in a patient with rubeosis iridis

Hyphema is the presence of blood in the anterior chamber of the eye. The blood may completely or partially cover the pupil and cause decrease in visual acuity. Other signs and symptoms of hyphema include visible blood in the front of the eye, pain, and sensitivity to light. The most common cause of hyphema is ocular trauma, usually a blunt or lacerating one. Other causes of hyphema include intraocular surgery, eye infections caused by herpes virus, cancer of the eye, artificial lens implants and blood clotting problems such as hemophilia, sickle cell anemia and von Willebrand disease. Hyphema may also occur spontaneously in conditions such as rubeosis iridis, juvenile xanthogranuloma, myotonic dystrophy and iris melanoma. The purpose of this case report is to point to the management of hyphema which occurs after administration of mydriatic drugs

Injuries related to animal sacrifice during the Feast of Sacrifice in Turkey

BACKGROUND: The Feast of Sacrifice is a significant annual religious festival in Muslim countries. In these festivals, thousands of animals are usually sacrificed by inexperienced individuals. Thus, many injuries occur during sacrificing of animals. OBJECTIVES: Describe injuries related to animal sacrifice or meat processing. DESIGN: Cross-sectional descriptive study. SETTING: Three hospitals in different cities of Turkey. SUBJECTS AND METHODS: Severity and type of injuries that occur during animal sacrifice or meat processing after the sacrifice and hospital costs. MAIN OUTCOME MEASURES: Identification and classification of sacrifice related injuries. SAMPLE SIZE: 301 injured individuals. RESULTS: The mean age of the patients was 42.5 (14.8) years and 83.1% of the subjects were male. Most (90.0%) injuries were penetrating injuries and 10.0% were blunt traumas. Upper and lower extremity injuries were identified in 77.4% and 17.9% of cases, respectively. Almost half of the injuries were on the left hand (49.8%). Almost all (96.6%) cases were treated and discharged from emergency services. Median hospital cost per patient was 103.14 Turkish Liras (35.95-852.66 Turkish Liras) (19.53 USD [6.80-161.48 USD]). CONCLUSIONS: Even though injuries related to animal sacrifice are usually caused by minor sharp objects, they can be severe and life threatening on rare occasions. To minimize the injuries that may occur during this period, public education and more convenient sacrifice centers may be helpful. LIMITATIONS: Small sample, single country, and short duration of the study. CONFLICT OF INTEREST: None. © 2020, Annals of Saudi Medicine, Saudi Arabia.

Risk-based analytical modelling of managerial processes in shipping business

Gemi işletmeciliği faaliyetleri uluslararası platformda, yüksek rekabet koşulları altında ve her geçen gün yükselen öz-denetim olgusu gibi kısıtlar altında yürütülmektedir. Bu tür kısıtlar, gemi işletmeciliğinde profesyonel anlayışa geçişe ve yenilikçi yürütme faaliyetlerine sürekli gelişim hedefi ile yönelimi tetikler. Son yıllarda, sertifikalandırma kuruluşları ve denizcilik danışmanlık grupları gemi işletmeciliği idarecilerine Entegre Yönetim Sistemini (EYS) ileri bir çözüm aracı olarak önermektedir. Gemi işletmeciliğinde EYS uygulamalarının kapsamı uluslararası tanınmış standartların gemi güvenliği ve gemilerden kaynaklanan kirliliğin önlenmesi ile ilgili zorunlu denizcilik kurallarıyla birleştirilmesi esası üzerinedir. Bu noktada, standart gereksinimlerinin uyumluluğu ve ilgili kuralların gemi işletmeciliği yönetim organizasyonuna entegrasyonu iki temel sorun olarak ortaya çıkmaktadır. Bu araştırma ile Bulanık Bilgi Aksiyomu (BBA), Hata Ağacı Analizi (HAA), Analitik Ağ Süreci (AAS) ve diğer başlıca Çok Ölçütlü Karar Verme (ÇÖKV) yöntemlerini de içeren bir Risk Bütünleşik Karar Destek Sistemi (RBKDS) geliştirildi. RBKDS, Veri Tabanlı Yönetim Sistemi (VTYS), Model Esaslı Yönetim Sistemi (MEYS), BBA esaslı Model Seçim Arayüzü (BBA-MSA), Entegre Süreç Yönetim Modülü (ESYM), İdari Karar Verme Modülü (IKVM) ve Risk Kontrol Ve Yönetim Modülü (RKYM) gibi unsurların bütünleştirilmesi ile oluşmuştur. Tamamlanan prototip uygulama ile RBKDS’ın EYS’nin süreç temelli entegrasyonu ve gemi işletmeciliğinde yönetimsel süreçlerin risk temelli analitik çözümü konusunda gemi işletmeciliği idarecilerini destekleyen nitel çıktılar ortaya koyduğu görülmüştür. Süreç idaresi prosedürlerinin yeniden tasarımına karar desteğinin yanı sıra, RBKDS, ayrıca farklı standartlar arası uyumsuzluk risklerini de göz önünde bulundurarak yönetimsel süreçler üzerine etkin karar vermeyi sağlamaktadır.   Anahtar Kelimeler: Gemi işletmeciliği, karar destek sistemi, entegre yönetim sistemi.Relevance to legislation in shipping business cycle, the International Maritime Organization (IMO) principally governs the safety and environmental protection via Flag State Implementation (FSI) and regional Port State Control (PSC) authorities in accordance with the designated Memorandum Of Understandings (MOUs). Although the IMO has adopted various conventions, mainly concerning marine safety, security, pollution prevention, and other relevant issues, enforcement of the international commitments and standards in trading activities of ships necessitate the involvement of maritime stakeholders. The IMO declared that there are now enough regulations in place and the problem is one of implementation and enforcement. In accordance with the recent trends in international maritime legislation, the implementation process of regulatory regime has become a competitive factor for the market players to achieve the sustainable development target in maritime transportation industry. Industrial response to this trend recalls the self-regulation. It is appeared as relatively a new regime for shipping business initiatives in maritime transportation industry. Extensively, the self-regulation dominates the industry and it mainly enforces the maritime stakeholders involvement in enhancement of the safety/environmental aspects for shipping business. Beside safety and environmental contributions, the self-regulation spontaneously ensures legislative performance of the relevant organizations such as classification societies, insurers, cargo owners, shippers, shipbrokers, ship managers, terminal operators and, ship financiers in trading activities satisfactorily. Implementation of an Integrated Management System (IMS) is one of the most effective and concrete instruments of managing the self-regulation phenomenon in order to respond to increasing demands from maritime society. In principle, the concept of IMS practices in shipping business is based on combining internationally recognized voluntary standards with the mandatory maritime 8regulations that are mainly concern with ship safety and the prevention of pollution from ships. In the early design phase of an IMS, cooperative efforts of maritime consultancies and relevant shipping executives targets to enable maximum improvement in managerial processes while reducing the costs and excessive bureaucracy in implementation of redesigned procedures. As potential clients, the third party groups such as cargo owners and contracted charterers have closely monitored the performance effects of IMS integration into professional shipping companies. Therefore, the managerial efforts are extremely valuable for the purpose of benefit from IMS implementations, which increase the reputation of ship management companies and provide an enormous trading advantage in maritime transportation industry. This research develops a Risk Integrated Decision Support System (RIDSS) based on a multi-methodological background includes Fuzzy Axiomatic Design (FAD) and Fault Tree Analysis (FTA), as well as Analytic Network Process (ANP) and other principal MCDM methods. The initial focus of the RIDSS is to reveal quantitative outcomes in order to encourage relevant shipping executives towards process-based integration of an IMS also to enhance risk-based analytical modelling of managerial processes in shipping business. The RIDSS consists of various modules such as Database Management System (DBMS), Model Base Management System (MBMS), FAD-based Model Selection Interface (FAD-MSI), Integrated Process Management Module (IPMM), Executive Decision-Making Module (EDMM), and Risk Control And Management Module (RCMM) with a high level of integrity. To demonstrate the proposed RIDSS, the mostly encountered managerial processes in commercial, technical, and operational levels of shipping business are then addressed and modelled. Specifically, the prototype application of the RIDSS incorporates the following process:(i) shipboard personnel recruitment, (ii) familiarization and training, (iii) performance appraisals of marine suppliers, (iv) marine equipment/spare purchasing, (v) fleet maintenance planning, (vi) accident analysis and prevention, (vii) Ship docking operations management, (viii) performance measurement for emergency drills. Besides decision aid to redesigning of process execution procedures through IMS requirements, the RIDSS also enables an effective decision-making on managerial processes even considering the potential risks of regulatory incompliance.  Keywords: Shipping business, decision support system, integrated management system.

Evaluation of physico-mechanical properties of Uşak-Karahallı marbles with their mineralogical-petrographic properties

Bu makalede Uşak İli Karahallı İlçesinde üç farklı mermer ocağından alınan numuneler üzerinde gerçekleştirilen bir dizi deneysel çalışmalar ile yöre mermerlerinin özellikleri belirlenmiştir. Numunelerin standartlara uygun biçimde saptanan fiziksel ve mekanik özellikleri; kimyasal, mineralojik ve petrografik özellikleri ile değerlendirilmiştir. Karahallı mermerlerinin birim hacim ağırlığı 2.69 gr/cm3 ile 2.74 gr/cm3 arasında değişim göstermektedir. Atmosfer basıncında ağırlıkça su emme değerleri ise %0.27-0.35 arasındadır. Karahallı mermerlerinde yapılan mekanik deneylerden tek eksenli basınç dayanımlarının 874.8 kg/cm2 ile 1027.9 kg/cm2 arasında değişmekte olduğu belirlenmiştir. Böhme aşınma dayanım değerleri ise 4.23 cm3/50 cm2 ile 5.50 cm3/50 cm2 arasındadır. Yöre mermerlerinin CaO oranları %52.9-55.4 arasındadır. Uşak Yeşil Mermeri diğer bölge mermerlerine göre daha yüksek oranda SiO2 (%5.06), TiO2 (%0.16) ve Fe2O3 (%1.25) içermektedir. Uşak Yeşil Mermerinin yüksek SiO2 içeriği mermerlere sert bir yapı kazandırmıştır. Opak mineraller, epidot ve mika minerallerin bileşimlerinde bulunan TiO2 ve Fe2O3 ana oksit değerlerindeki kısmi zenginleşmenin bu mermere açık yeşil renk verdiği belirlenmiştir.In this article, the characteristics of the local marbles were determined by a series of experimental studies carried out on the samples taken from three different marble quarries in the Karahallı District of Uşak. The physical and mechanical properties of the samples determined in accordance with the standards evaluated together with their chemical, mineralogical and petrographic properties. Unit volume weight varies between 2.69 gr/cm3 and 2.74 gr/cm3 while water absorption values by weight at atmospheric pressure are between 0.27-0.35 % in Karahallı marbles. Uniaxial compressive strength values from the mechanical tests performed on Karahallı marbles are determined between 874.8 kg/cm2 and 1027.9 kg/cm2. Böhme abrasion resistance values are between 4.23 cm3/50 cm2 and 5.50 cm3/50 cm2. The CaO ratios of the marbles of the region are between 52.9-55.4%. The Uşak Green Marble contains a higher percentage of SiO2 (5.06%), TiO2 (0.16%) and Fe2O3 (1.25%) compared to other region marbles. The high SiO2 content of the Uşak Green Marble gives this marble a hard structure. It was determined that partial enrichment in TiO2 and Fe2O3 main oxide values in the compositions of opaque minerals, epidote and mica minerals gave this marble a light green color

Karbonat kökenli doğaltaşlarda tane boyutu ile Knoop sertlik değeri arasındaki ilişkinin incelenmesi

Doğaltaşlarda sertlik kavramının miktarını belirleyen en önemli özellikler mineral bileşimi, tane boyu ve dokudur. Knoop sertliği tayini için karbonat bileşimli metamorfk ve sedimanter kökenli 10 farklı mermer türü kullanılmıştır. Bu mermerlerin mikroskop incelemeleri ile mineral bileşimi, tane boyutu ve dokusal özellikleri belirlenmiştir. Mikro sertlik cihazı ile her bir örnekten 40 iz ölçülerek Knoop sertlik değerleri bulunmuştur. İncelenen mermerler içerisinde en düşük Knoop sertlik değerine sahip mermerin 135 HK ile Muğla Beyaz, en yüksek Knoop sertlik değerine sahip mermerin ise 180 HK ile Rosalia Dark olduğu belirlenmiştir. Mermerlerin Knoop sertlik ve tane boyutu değerleri karşılaştırılmış ve aralarında ters orantı olduğu belirlenmiştir. Tane boyutu büyüdükçe Knoop sertlik değerinin azaldığı görülmüştür.The most important properties identifying the amount of hardness concept in natural stones are mineral composition, grain size and texture. In order to specify the Knoop hardness, ten different types of marbles were used consisting of carbonate composed metamorphic and sedimentary based. With the examination of these marble specimens under the microscope, their mineral composition, grain size and texture properties were specifed. Their Knoop hardness values were found by measuring 40 indents under micro hardness tester. Among the marble specimens examined it was specifed that Muğla White had the lowest Knoop Hardness with 135HK and Rosalia Dark had the highest with 180 HK. Knoop hardness and grain dimension values of the marbles were compared and found that there is an inverse proportional relationship between them, as the grain dimension increases, Knoop hardness value decreases
