The purpose of this study is to investigate the tensile and flexural properties of unidirectional coconut fiber/polyester composite materials, and to describe their failure modes. Specimens were cut from fiber/polyester composite plates containing various fiber contents. Materials being used in this study are coconut fiber that was previously alkali-treated and polyester resin matrix. Whilst tensile testing was carried out in accordance with the ASTM D3039 standard, flexural testing was based on the ASTM D790 standard. Failure surfaces of the representative specimens were then observed under an optical microscope, and their digital photo macrographs were captured for image analysis in order to describe their respective fiber distribution pattern and to determine their respective actual fiber volume fraction, Vf, by means of an open source software called ImageJ. It was found out that the actual Vf of the four composite plates being produced were 10.7%, 17.6%, 27.4% and 40.5%. It was revealed that while tensile strength increases with the increase of Vf, while failure strain, modulus elasticity and flexural strength decreases. The average highest tensile strength, tensile failure strain, and tensile modulus of elasticity were found being 30.01 MPa at Vf = 40.5%, 0.027 mm/mm at = 0%, and 1.47 GPa at Vf = 0%, respectively. The average highest flexural strength, failure strain and modulus of elasticity were observed being 153.92 MPa at Vf = 10.7%, 0.0358 mm/mm at Vf = 0%, and 3.242 GPa at Vf =10.7%, respectively. It was observed that specimens were failed by fiber pull out and debonding.

Welded join failure analysis of broken jetty head strut has been carried out to find out the root cause of the failure which was obverved at the ring welding. Specimens being made of unbroken and broken struts were characterized and analyzed. The results show that the chemical composition of the based metal and the strut welded joins especially their phosporus content were close to that of the ASTM A 252 grade 2 standard. A common phenomenon was noted on the hardness testing result where the hardness numbers of the weld metal zone were found being higher than those of the base metal. The Widmanstatens stucture was noticed on both the weld metal and the coarse grain zone. Further examination of the macrostructures revealed that blow holes and incomplete fusions were detected on the weld metal of the broken struts. These flaws may the root cause of the failure because they acted as an initial crack that may propagate until fracture.

Time and cost are very infuential to the success and failure of a project. The measurement of project can be seen by the short time arrangment and minimum cost without denying the quality of project result. Systematically project management is very needed to make sure the time of project realization appropriate with the contract or it can be done faster so the cost will be able to be pressed. Moreover it is also to avoid paying the fine caused by the project lateness. The purpose of this research is to calculate the cost change and time project arrangment by adding work time variation and employed increment, then compare the result between fine cost and cost changing after the overtime and employee increment. Data in this research is secondary data from implementer contractor. Data analysis is used Microsoft Project 2007 program and time cost trade off method. The result from Microsoft Project 2007 program is critical path and result from time cost trade off method is duration velocity and increment cost in every activity that fasten. The result of this research indicated that (1) Time and cost optimum result of the adding work time (overtime) obtained at the age of project 242 days of work with total cost of project Rp. 10.481.732.644,58 with time efficiency project 24 days (9,02%) and cost efficiency project Rp. 43.019.556,39 (0,41%).

Pengaruh Beban Pada Permukaan Tanah Dan Frekuensi Gempa Terhadap Respon Seismik Linier Elastis Lapisan Tanah
Authors: Pujianto As’at 
Published: March 2022

Respon seismik lapisan tanah akibat gempa merupakan suatu parameter gerakan tanah akibat gempa. Selama getaran merambat dari pusat gempa sampai ke permukaan tanah, maka faktor tanah sebagai penghantar getaran mempunyai peran yang sangat penting. Berbagai parameter penting mengenai jenis tanah tersebut meliputi keadaan geologi secara lokal dan kondisi tanah itu sendiri. Di samping itu juga ada beberapa faktor yang berpengaruh terhadap respon tanah, di antaranya adalah indeks plastisitas (PI), kandungan frekwensi gempa serta keadaan beban diatas permukaan lapisan tanah. Beban pada permukaan lapisan tanah akan berpengaruh terhadap kekakuannya. Kekakuan tanah yang mempunyai beban lebih kecil akan berbeda dengan tanah yang mempunyai beban lebih besar. Dengan keadaan seperti itu maka tanah yang mempunyai berat beban bangunan berbeda akan menghasilkan respon yang berbeda juga. Penelitian dengan menggunakan satu data profil tanah tanpa beban dan lima variasi pembebanan telah dilakukan, akibat gempa Koyna dan Bucharets yang telah dinormalisai, sehingga hanya mempunyai perbedaan frekuensi. Analisis hitungan menggunakan program sederhana dengan dasar metode analisis dinamika struktur “Multi Degree of Freedom” dan pemodelan matematis lapisan tanah berupa model “Shear Building” serta penyelesaian problema dinamik dengan metode numerik “Central Difference”. Hasil analisis menunjukan bahwa Semakin besar beban mengakibatkan simpangan semakin kecil. Dengan percepatan maksimum sama akibat gempa Koyna dan Bucharest, namun mempunyai frekuensi yang berbeda, mengakibatkan respon yang tidak sama besar. Parameter percepatan tanah bukan satu-satunya parameter yang dapat dipakai untuk mengetahui damage potential suatu gempa tetapi terdapat parameter lain yang harus diperhatikan. Kandungan frekuensi gempa Koyna maupun Bucharest terhadap frekuensi struktur masih cukup jauh (tidak berimpit), sehingga jika terjadi gempa dengan frekuensi tersebut struktur tanah tidak akan mengalami resonansi.

Published: March 2022

Penyesuaian impedansi merupakan suatu masalah yang sangat penting untuk diperhatikan pada saat menginstalasi antena suatu pemancar. Gelombang yang dipantulkan kembali ke pemancar akan mengakibatkan panas dan kerusakan pada penguat akhir pemancar, sehingga menyebabkan penurunan daya atau daya yang dihasilkan oleh pesawat pemancar tidak akan maksimal. Penelitian dilakukan untuk mengetahui seberapa besar impedansi antena berkontribusi pada matching impedance (penyesuaian impedansi), menggunakan metode single stub tuner. Hasilnya adalah Pada pengukuran yang menggunakan kabel koaksial RG-55 A/U, posisi paling match terjadi pada jarak 30 cm dari antena ke arah generator sehingga stub dipasang secara permanen pada jarak tersebut, sedangkan pada pengukuran yang menggunakan kabel koaksial 5D-2W, posisi paling match terjadi di antena itu sendiri dan tidak ditemukan posisi match pada saluran sehingga stub tidak dipasang. Pada kabel koaksial RG-11/U, posisi paling match terjadi pada jarak 20 cm dari antena ke arah generator sehingga stub dipasang secara permanen pada jarak tersebut.

Aim: In thoracic surgery, many factors; such as long duration of surgery and the use of volatile anesthetics may increase the frequency of postoperative nausea/ vomiting (PONV). Recent studies suggests that inflammatory markers such as neutrophils lymphocytes ratio (NLR) can predict PONV. The aim of this study is to postoperatively examine the role of demographic, laboratory, and clinical data in predicting PONV in patients who underwent thoracotomy and received thoracic epidural analgesia (TEA).
Material and Methods:Data were collected for patients who underwent elective thoracic surgery and were administered TEA between March 2017 and December 2020. Patients' demographic data, laboratory parameters, and clinical characteristics; such as American Association of Anesthesiologists (ASA) I-II-III, erythrocyte distribution width (RDW), NLR, postoperative visual analog scale (VAS), were scanned. All patients who developed PONV were included in Group 1. Hospital records were used to select Group 2 patients who did not develop PONV.
Results: The incidence of PONV was determined as 14.77%. There was a statistically significant difference between the groups in terms of ASA and 24-hour VAS scores (p < 0.05). Patients with PONV had statistically significantly higher 24-hour VAS scores(p < 0.05). PONV was statistically significantly higher in patients with ASA III compared to other ASA groups (p < 0.05). Multivariate analysis suggests that ASA, RDW and 24-hour VAS are significant in predicting PONV. Lower RDW, higher ASA and 24-hour VAS increase the risk of PONV.
Conclusion: Demographic data, laboratory parameters, and clinical characteristics were evaluated concerning their correlation with PONV in this study. It was observed that the frequency of PONV might increase in patients with low RDW levels. In addition, higher VAS values and ASA physical score were also found to increase the risk of PONV in patients who underwent thoracotomy and administered TEA

Amaç: Ciddi Aort Darlığı (AD) olan hastalarda TAVI ,aort kapak obstrüksiyonunu ortadan kaldırarak kardiyak outputu arttırır. Sol ventrikülden çıkan akımın iyileşmesi, böbreklerin kan akımını artırarak renal perfüzyonu artırır ve bozulmuş renal fonksiyonun düzelmesini sağlayabilir. Bunun yanında, TAVI sırasında kontrast madde kullanımına bağlı ya da transfemoral kateterizasyon sırasında aterom plaklarının ve kolesterol kristallerinin saçılması sonucu alt ekstremite veya renal arter embolizasyonuna bağlı akut böbrek yetersizliği gelişebilir. Bu çalışmanın amacı; TAVI’nın böbrek fonksiyonları üzerine 1. aydaki etkisini belirlemek ve hastaların eşlik eden hastalıklarının sonuca etkisi olup olmadığını saptamaktı.
Gereç ve Yöntemler:Bu çalışmaya, 2015-2019 yılları arasında ciddi AD ile takip edilip TAVI yapılan toplam 68 hasta dahil edildi. Tüm hastalarda işlem öncesi ve işlemden 1 ay sonra bakılan kreatinin ve GFR değerleri cinsiyete ve eşlik eden hastalıklara göre retrospektif olarak belirlendi ve değerlendirmeler bu temelde yapıldı.
Bulgular: Hastaların ortalama yaşı 78.6+7,86, ortalama sol ventrikül ejeksiyon fraksiyonu ise (LVEF ) %56.1+7,82 idi. Mevcut sonuçlar, AD’nIn düzeltilmesinden sonra 1. ayda komorbiditesi bulunan hastaların böbrek fonksiyonlarında düzelme olmadığını aksine ek hastalığı olmayan hastalara göre anlamlı derecede kreatinin değerlerinde artma ve GFR değerinde düşme olduğunu göstermektedir. Diğer komorbidite durumlarının aksine işlem öncesi kronik böbrek hastalığı olanlarda ise 1. ayda kreatinin değerlerinde anlamlı bir artış saptanmamıştır .
Sonuç: Çalışmamızda işlem öncesi kronik böbrek hastalığı olan hastalarda böbrek koruması açısından daha titiz olunduğunu ve bu hastalarda kronik böbrek hastalığına sebep olan majör etkenin ciddi AD olması sebebiyle ciddi AD'nın ortadan kalkması ve buna bağlı artan kardiyak debinin böbrek fonksiyonları üzerine olumlu etki yaratarak denge sağladığını düşünüyoruz.

Authors: ÇELİK Deniz , YILDIZ Murat 
Published: March 2022

Giriş: COVID-19 pandemisi nedeniyle sağlık personelinde el hijyeni, alkol bazlı dezenfektan kullanımı, eldiven, maske ve diğer bariyer önlemlerin kullanımında farkındalık artışı gözlenmektedir. Çalışmamızın amacı, 2019 ve 2020 yıllarının ilk 6 aylarında COVID-19 tanısı dışlanmış, yoğun bakım izlemi gereken hastalarda oluşan enfeksiyonların oranlarında bir farklılık olup olmadığını karşılaştırmaktır.
Gereç ve Yöntemler: 01/01/2019-30/06/2019 arasındaki 6 ay süreyle (kontrol grubu) ve 01/01/2020-30/06/2020 arasındaki 6 ay süreyle (vaka grubu) ikinci basamak Göğüs Hastalıkları Yoğun Bakım Ünitesine (GYBÜ) kabul edilen tüm hastalar çalışmaya dahil edildi. Çalışmamızda hariç bırakma kriteri yoktu. COVID-19 PCR pozitifliği tespit edilen veya COVID-19 PCR testi negatif olsa da klinik ve radyolojik kuşkuyla COVID-19 hastalığı düşünülen, ve/veya spesifik tedavi başlanmış/devam eden hiçbir hasta bu dönemde bu yoğun bakımımıza alınmadığı için çalışmamıza da dahil edilmediler.
Bulgular: Çalışmanın kontrol grubu (n=327) ve vaka grubu (n=260) demografik bulgular ve genel özellikleri bakımından benzerdi. Gruplar arasında yaş, cinsiyet, hastanın GYBÜ’ne nakil geldiği yer, hastanın taburcu edildiği yer, GYBÜ öncesi üçüncü basamak yoğun bakımda entübasyon öyküsü, evde USOT ve/veya NIMV cihazlarının bulunması, eve raporlanan cihaz tipleri ve taburculuk sonrası takipte mortalite durumları, GYBÜ’de NIMV ihtiyacının olması ve NIMV gün sayısı, üçüncü basamak YBÜ’de yatış gün sayısı ve NIMV uygulama gün sayısı açısından gruplar arasında istatistiksel olarak anlamlı ilişki bulunmadı. Kontrol grubu ile vaka grubu arasında hastalardan alınan tüm kültürlerin üreme durumu ve kültürlerde üreyen mikroorganizmalar açısından istatistiksel olarak anlamlı farklılık izlenmedi (sırasıyla; p=0.775 ve p=0.137).
Sonuç: Çalışmamızda GYBÜ’de çalışan sağlık personelinin el hijyeni ve bariyer önlemler hakkında farkındalığında artış olmasına rağmen gerek yüksek riskli dirençli bakteriyel üremelerde dönemler arasında farklılık izlenmemesi gerekse de tanı konulan enfeksiyonlarda dönemler arasında farklılık olmaması enfeksiyon kontrol önlemlerinin içselleştirildiğini ve uygulandığını göstermektedir.

Aim: Inflammation and malnutrition are poor prognostic markers in acute coronary syndromes. In this study, we aimed to investigate the association between high sensitive modified Glasgow prognostic score (HS-mGPS), derived from C-reactive protein and serum albumin levels, and in-hospital mortality of elderly patients with non-ST elevation myocardial infarction (NSTEMI).
Material and Methods: Included subjects were recruited from three different tertiary health centers. Totally, 282 eligible patients aged >65 years with diagnosis of NSTEMI were retrospectively enrolled. Global Registry of Acute Coronary Events (GRACE) risk score for in-hospital mortality and HS-mGPS was calculated for each patient. Subjects were categorized according to their inflammation-based scores ((high HS-mGPS group (HS-mGPS ≥1, n=124) vs. low HS-mGPS group (HS-mGPS =0, n=158)).
Results: Both groups were similar regarding admission blood pressure levels, coronary angiography findings, treatment modalities and GRACE scores. Patients with high HS-mGPS had higher admission heart rate and longer hospitalization duration compared to low HS-mGPS group. In-hospital mortality rates were higher in high HS-mGPS group compared to low HS-mGPS group (21.8% (n=27) vs. 3.2% (n=5), respectively, P

Published: March 2022

Amaç: Hemodiyaliz amaçlı Arteriovenöz (AV) fistül oluşturulmasında enfeksiyon ve erken trombozdan korunmak için heparin ve antibiyotiklerin preoperatif kulanım gerekliliği halen tartışılmaktadır. Bu yazıda, iki farklı nosyon retrospektif olarak karşılaştırıp bu gerekliliği tartışmaktayız.
Gereç ve Yöntemler:2015-2020 yılları arasında hemodiyaliz amaçlı tüm AV fistül ameliyatlarını inceledik. 456 hastanın 242'sine herhangi bir premedikasyon uygulanmazken, diğer 214 hastaya işlem öncesi 80-100 mg/kg heparin ve 1 gr sefazolin iv verildi ve taburcu olduktan sonra antibiyotik tedavisi 1 haftaya tamamlandı. Bu iki farklı yöntemin enfeksiyon ve erken dönem açıklık oranlarını karşılaştırdık.
Bulgular: Ön kol AV fistül oluşturulan hastalar heparin ve antibiyotik kullanan premedikasyon grubu ile kontrol grubu olarak gruplandırıldı. Gruplar arasında komorbit hastalıklar ve demografik veriler açısından fark yoktu. İstatistiksel olarak anlamlı olmasa da premedikasyon grubunda hematom oranları yüksek saptandı (%2, %0,9, p=0,45). Postoperatif ilk kontrolde erken açık kalma oranları ve 3 ayda diyalize ulaşan fistül oranları açısından anlamlı bir fark yoktu. Her iki grupta da fistül enfeksiyonu gözlenmedi.
Sonuç: Premedikasyon olarak heparin ve antibiyotikler damar yolu girişimlerinde enfeksiyonun önlenmesine veya erken trombozu önlenmesine katkı sağlamamaktadır. AV fistül oluşturma herhangi bir antibiyotik ve heparin olmadan güvenle yapılabilir.

Published: March 2022

Aim: In this study, we aimed to compare brown adipose tissue (BAT) activity on 18F-Flourodeoxyglucose Positron Emission Tomography (PET)/Computed Tomography(CT) in patients with and without active cancer.
Material and Methods: Results of the patients who underwent 18F-FDG PET/CT between January 2014 and February 2018 in Nuclear Medicine Department were evaluated retrospectively. Age, gender, body mass index (BMI), serum levels of glucose, bilirubin, total cholesterol (T-chol), low-density lipoprotein (LDL) and triglyceride (TG) of the patients were noted from the hospital database. Mean outdoor temperature of the day during PET/CT imaging was searched from National Weather Service archives. Diagnosis and disease activity status on PET/CT imaging were evaluated retrospectively. Standardized uptake value (SUV) and brown adipose tissue volume (BAV) were calculated on PET/CT images. Additionally, hepatic attenuation index and subcutaneous adipose tissue thickness (SCATT) were calculated from CT images. Difference between median SUV and BAV among groups with and without active cancer was analyzed.
Results: Totally 78 (54 F; 24 M; mean age 34.415.6) patients who underwent 18F-FDG PET/CT for different oncological indications were included in the analysis. All the patients had different degrees of BAT uptake on PET/CT images. Median (min-max) values for SUV, BAV and SCATT were found as 8.0 (2.7-37.0), 26.9 (2.1- 116.0) cm3 and 15.0 (3.0- 46.0) mm, respectively. Hepatic attenuation index was 0-5%, 6-30% and >30% in 56 (71%), 20 (26%) and 2 (3%) patients, respectively. Active disease was observed in 26 (33%) patients during PET/CT imaging. In the evaluation of the distribution of the adipose tissue parameters, median SUV (p=0.008) and BAV (p=0.008) of groups with and without active cancer were found statistically significant.
Conclusion: BAT activity in patients with active cancer seems to be higher than that in patients without active disease, supporting the possible role of adipose tissue activation on cancer development and progression.
Can systemic inflammatory index (SII) and MELD score predict survival in liver metastatic colorectal cancer?
Authors: KARADAĞ İbrahim , KARAKAYA Serdar 
Published: March 2022

Aim: In this study, it was aimed to investigate whether the blood neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR) and model for end-stage liver disease (MELD) score at the time of liver metastasis in colorectal cancers (CRC) predict overall survival (OS) and their prognostic roles.
Materials and Methods: 1250 colorectal cancer patients followed up in our oncology center between 2015-2020 were retrospectively screened and 203 patients with liver metastatic colorectal cancer (LMCRC) were included in the study. Blood NLR, PLR and MELD scores at the time of liver metastasis were calculated retrospectively .
Results: Liver specific OS (LSOS) was 22 months (95% CI: 16.82-27.18) in patients with an NLR ratio of 2.5 or less, while it was 10 months (95% CI: 6.59-13.41) in patients with an NLR rate above 2.5 (p=0.004). LSOS was 19 months (95% CI: 14.33-23.36) in patients with a PLR rate of 150 or less, and 10 months (95% CI: 5.52-14.47) in patients with a PLR rate above 150 (p=0.0042). There was a negative correlation between MELD score and LSOS (r.-0.152, p=0.031). In the multivariate regression analysis, high NLR rate was found to be an independent prognostic factor for LSOS (HR:95% CI:1.08-1.98).
Conclusion: In this study, it was shown that higher NLR, PLR and MELD scores are associated with worse survival in LMCRC. NLR was revealed to be an independent prognostic factor for LSOS. Closer follow-up may be an option in patients with high SII and MELD scores when liver metastasis develops.
