Muhsin Balaban,Ahmet Selimoglu,Rahim Horuz,Oktay Akca,Selami Albayrak 대한비뇨의학회 2013 Investigative and Clinical Urology Vol.54 No.7

Metastatic malignant melanoma of the prostate is extremely rare in clinical practice,and only one case has been reported in the English literature in the past 30 years. We report a case of malignant melanoma that metastasized to the prostate and review the current literature. A 50-year-old man with a history of malignant melanoma metastasis to the left axilla, which was excised 3 years ago, presented with lower urinary tract symptoms and gross hematuria. He underwent cystoscopy and transurethral resection of the prostate. The pathological examination showed metastatic malignant melanoma of the prostate gland. The patient died 6 months after the transurethral resection.

FEA of the blast loading effect on ships hull

Hamdoon, Muhsin,Zamani, Nader,Das, Sreekanta Techno-Press 2011 Ocean systems engineering Vol.1 No.3

In combat operations, naval ships may be subjected to considerable air blast and underwater shock loads capable of causing severe structural damage. As the experimental study imposes great monetary and time cost, the numerical solution may provide a valuable alternative. This study emphasises on numerical analysis for optimization of stiffened and unstiffened plate's structural response subjected to air blast load. Linear and non linear finite element (FE) modeling and analysis was carried out and compared with existing experimental results. The obtained results reveal a good agreement between numerical and experimental observations. The presented FE models can eliminate confusion regarding parameters selection and FE operations processing, using commercial software available currently.

Reversible Color and Gray-scale Based Images in Image Hiding Method Using Adding and Subtracting Operations

Salim Muhsin Wadi,Nasharuddine Zainal 한국산학기술학회 2014 SmartCR Vol.4 No.3

A new reversible high capacity hiding algorithm using decomposition and simple arithmetic operations is proposed in this paper for hiding gray-scale and RGB images. Generally, the three factors that should be taken into account in hiding algorithms are the capacity, security, and invisibility of secret information. The Least Significant Bit method is a popular technique to hide operations in the spatial domain. A number of methods were proposed to enhance the performance of the Least Significant Bit method. However, the capacity and security levels of those algorithms are low. The target of the proposed algorithm is implementing hiding capacity about 75% (6 bits per pixel) to hide an image in another image of the same size and type. In this paper, we use an encrypted image as a cover image to reduce the effects of distortion. The bit planes that result from decomposing the secret image will be reordered and scrambled before the hiding operation to make it invisible. Also, the hiding operation is achieved by subtracting or adding numbers to the host pixel value based on the value of the secret pixel to increase the security level. Experimental results show that the capacity of the proposed method is perfect with a high quality of the extracted image, which is strong against many attackers.

Yilmaz Kocak,Muhsin Savas 사단법인 한국계산역학회 2016 Computers and Concrete, An International Journal Vol.17 No.6

This study has been carried out to investigate the effect of the surface properties of Portland cement, diatomite and zeolite on the performance of concrete composites. In this context, to describe the materials used in this study and determine the properties of them, chemical, physical, mineralogical, molecular, thermal, and zeta potential analysis have been applied. In the study, reference (Portland cement), 10%–20% diatomite, 10%–20% zeolite, 5+5%–10+10% diatomite and zeolite were substituted for Portland cement, a total of 7 different cements were obtained. Ultrasonic pulse velocity, capillary water absorption and compressive strength tests were performed on the hardened concrete specimens. Hardened concrete tests have been done on seven different types of concrete, for 28, 56 and 90 days. As a result of experiments it has been identified that both the zeolite and diatomite substitution has a positive effect on the performance of concrete.

Corticosteroid Therapy Improves the Outcome of Semen Analysis in an Oligozoospermic Patient With Epididymal Sarcoidosis

Onder Canguven,Muhsin Balaban,Ahmet Selimoglu,Selami Albayrak 대한비뇨의학회 2013 Investigative and Clinical Urology Vol.54 No.8

Sarcoidosis is a multisystem, inflammatory disorder characterized by the presence of noncaseating epithelioid granulomas. Sarcoidosis can involve the genitourinary system by affecting the kidney and genitals. Most characteristic genital lesions proceed to granuloma and can comprise the epididymis, testis, and vas deferens. Few case reports have been published on this rare entity. We report a case in which a man presented with bilateral epididymal sarcoidosis and severe oligospermia. Corticosteroid treatment, which was applied in gradually decreasing doses for 6 months, dissolved the testicular granuloma. Consequently, semen analysis demonstrated a significant increase in the sperm count to within normal limits.

Diversity and Ecology of Myxomycetes from Kutahya and Konya (Turkey) with Four New Records

( Ijlal Ocak ),( Muhsin Konuk ) 한국균학회 2018 Mycobiology Vol.46 No.3

In this study, we examined myxomycetes that developed in moist chamber cultures of substrata material collected from K€utahya and Konya provinces in Turkey. We collected bark samples from living trees, plant litter from the ground, standing dead wood or stumps, and downed and decayed wood or bark and placed them in the moist chamber cultures. We identified 36 species belonging to 12 genera of myxomycetes. The species determined are listed, and four new records, Didymium balearicum Ing, Macbrideola oblonga Pando & Lado, Paradiacheopsis erythropodia (Ing) Nann-Bremek. and Perichaena pedata (Lister & G. Lister) G. Lister, are added to the mycoflora of Turkey.

Effects of hull form parameters on seakeeping for YTU gulet series with cruiser stern

Ferdi Cakici,Muhsin Aydin 대한조선학회 2014 International Journal of Naval Architecture and Oc Vol.6 No.3

This study aims to identify the relations between seakeeping characteristics and hull form parameters for YTU Gulet series with cruiser stern. Seakeeping analyses are carried out by means of a computer software which is based on the strip theory and statistical short term response prediction method. Multiple regression analysis is used for numerical assessment through a computer software. RMS heave-pitch motions and absolute vertical accelerations on passenger saloon for Sea State 3 at head waves are investigated for this purpose. It is well known that while ship weight and the ratios of main dimensions are the primary factors on ship motions, other hull form parameters (CP, CWP, CVP, etc.) are the secondary factors. In this study, to have an idea of geometric properties on ship motions of gulets three di-fferent regression models are developed. The obtained outcomes provide practical predictions of seakeeping behavior of gulets with a high level of accuracy that would be useful during the concept design stage.

Nazlican, Ersin,Akbaba, Muhsin,Okyay, R. Azim Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.6

Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death in females in Turkey. The main problems experienced by women with breast cancer are physical losses, emotional distress and degradation in family, work and social roles. The purpose of this cross-sectional retrospective study was to investigate the socio-demographical characteristics and depressive symptoms of 125 newly diagnosed cases with breast cancer reported to cancer control department of Hatay provincial health directorate in 2011. To evaluate the depressive symptoms the Beck Depression Inventory (BDI) was used. All 125 cases who participated in the study were female. The mean age was $49.2{\pm}11.9$. The mean BDI score of the cases was $17.5{\pm}10.6$. The number of cases whose BDI scores were 17 and above was 65 (52.0%), and the number of cases whose BDI scores were under 17 was 60 (48.0%). The most striking finding in our study was that only 4 of the cases were receiving psychological help and support. The rate of depression was found high in our study and psychological support is a must for patients with a life threatening disease such as cancer.
