Objectives: This study examined the overweight, obesity, dietary habits, and physical activity among Hispanic college students. Methods: Eighty seven (n=87, age= 24.03 ± 5.69) Hispanic college students participated in the study. Descriptive and anthropometric measurements including resting heart rate (RHR), resting blood pressure (RBP), height, weight, body mass index (BMI), circumference measurements [waist at narrowest point (Xiphoid), and hip at widest point (Hip), body composition (BC) were collected. Subjects completed the Dietary Screener Questionnaire (DSQ). PA was estimated via Godin’s (2011) Leisure-Time Exercise Questionnaire. Results: The mean BMI was 27.29±6.20 kg/m2, in the overweight range. The mean WC for males was 90.86±13.23 and for females was 82.35±14.61. Independent t-test showed that males had significantly higher values in height (p<0.01), weight (p<0.01), WC (p<0.01), and PA (p<0.01) compared to females. DSQ data indicated that participants consumed fruits, green leafy or lettuce salad, and milk less than recommended amount. It also showed high intake of sugary food. Conclusions: Hispanic young adults are in a poorest condition regarding the level of obesity as opposed to White and African American counterparts. This may be due to the decrease in PA. Diet behavior; less consumption of dairy, fruits and vegetable but frequent consumption of high sugary might be related to obesity in Hispanic young adults.

Muhammet Karabulut,Murat Emre Kartal 국제구조공학회 2019 Structural Engineering and Mechanics, An Int'l Jou Vol.72 No.2

The effect of galleries on the earthquake behavior of dams should be investigated to obtain more realistic results. Therefore, a roller compacted concrete (RCC) dam with and without galleries are examined under ground motion effects. For this purpose, Cine RCC dam constructed in Aydın, Turkey, is selected in applications. The optimal mesh around galleries is investigated to obtain the most realistic results. Two-dimensional finite element models of Cine RCC dam with and without galleries are prepared by using ANSYS software. Empty and full reservoir conditions were taken into account in the time-history analyses. Hydrodynamic effect of the reservoir water was taken into account considering two-dimensional fluid finite elements based on the Lagrangian approach. It is examined that how principle stresses and displacements change by height and during earthquake. The dam-foundation-reservoir interaction was taken into consideration with contact-target element pairs. The displacements and principle stress components obtained from the linear analyses are compared each other for various cases of reservoir water and galleries. According to numerical analyses, the effect of galleries is clear on the response of RCC dam. Besides, hydrodynamic water effect obviously increases the principle stress components and horizontal displacements of the dam.

This study presents comparation of fixed and viscos boundary condition effects on three-dimensional earthquake response and performance of a RCC dam considering linear and non-linear response. For this purpose, Cine RCC dam constructed in Aydın, Turkey, is selected in applications. The Drucker-Prager material model is considered for concrete and foundation rock in the nonlinear time-history analyses. Besides, hydrodynamic effect was considered in linear and non-linear dynamic analyses for both conditions. The hydrodynamic pressure of the reservoir water is modeled with the fluid finite elements based on the Lagrangian approach. The contact-target element pairs were used to model the dam-foundation-reservoir interaction system. The interface between dam and foundation is modeled with welded contact for both fixed and viscos boundary conditions. The displacements and principle stress components obtained from the linear and non-linear analyses are compared each other for empty and full reservoir cases. Seismic performance analyses considering demand-capacity ratio criteria were also performed for each case. According to numerical analyses, the total displacements and besides seismic performance of the dam increase by the effect of the viscous boundary conditions. Besides, hydrodynamic pressure obviously decreases the performance of the dam.

Exploring Driver Injury Severity Using Latent Class Ordered Probit Model: A Case Study of Turkey

Nihat Can Karabulut,Murat Ozen 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.3

There have been limited efforts to study the severity of traffic crashes in Turkey. This study is probably the first attempt to investigate the factors that contribute to driver injury severity patterns. Fatal injury crash data from 2015 to 2017 for the city of Mersin was used. A two-step approach was employed. First, latent class clustering was performed to capture unobserved heterogeneity inherent in the crash data. The crash database was separated into four clusters by maximizing the homogeneity within each cluster. Then, an ordered probit model was developed on each cluster to explore the factors that significantly affect the driver injury outcomes. Marginal effects were calculated to interpret the influence of significant variables across the injury levels in more detail. The presence of motorcycles, fixed objects, and run-off-road crashes were found to be the main factors associated with injury and fatality in all clusters. The results underlined the association between driving behavior and injury severity of drivers. Alcohol-impaired driving, speeding, and traffic sign/signal violations increase the likelihood of severe injury.

Purpose: Although spontaneous intramural hematomas of the gastrointestinal tract are very rare, they may be observed with the use of oral anticoagulant, though less frequently in cases of hematological malignancy and other bleeding disorders. Cases diagnosed as spontaneous intramural hematoma have been assessed in our clinic. Methods: The cases, which were diagnosed as spontaneous intramural hematoma in the gastrointestinal tract (SIHGT) following anamnesis, physical examination, biochemical, radiological and endoscopic findings from July 2008 to July 2012, have been assessed retrospectively. Results: Seven out of 13 cases were women and the mean age was 65.1 years (34 to 82 years). The most frequent complaint on admission was abdominal pain. The most frequent location of SIHGT was the ileum (n = 8). Oral anticoagulant use was the most common cause of etiology (n = 12). In 10 cases, International normalized ratio values were higher than treatment range (2 to 3, where mechanical valve replacement was 2.5 to 3.5) and mean value was 7.6 (1.70 to 23.13). While 12 cases were discharged without problems with medical treatment, one case with acute myeloid leukemia died in the intensive care unit following cerebrovascular attack. Conclusion: Spontaneus bleeding and hematomas that may arise in connection with bleeding diathesis may be fatal in cases with long-term oral anticoagulant treatment and insufficient follow-up. In management of these cases, it may be necessary to arrange conservative follow up and/or initialize low molecular weight heparin, and administer vitamin K as well as replace blood products and coagulation factors when indicated.

Background: The role of second-line therapy in metastatic pancreatic cancer is not clear. In this study, we aimed to explore the second-line efficiency of capecitabine and oxaliplatin (XELOX) in patients with advanced pancreatic cancer who have received gemcitabine-based first-line therapy. Materials and Methods: We retrospectively evaluated 47 patients with locally advanced or metastatic pancreatic cancer previously treated with gemcitabine-based first-line regimens. Treatment consisted of oxaliplatin $130mg/m^2$ and capecitabine $1000mg/m^2$ twice daily with a 3 week interval, until unacceptable toxicity or disease progression. Results: Median number of cycles was 4 (range, 2-10). The overall disease control rate was 38.3%. The median overall survival and progression-free survival from the start of second-line therapy were 23 weeks (95%CI: 16.6-29.5 weeks) and 12 weeks (95%CI: 9.8-14.4 weeks), respectively. The most common grade 3-4 toxicities were nausea, vomiting and hematologic side effects. Conclusions: Our result suggests that the combination of capecitabine and oxaliplatin was tolerated with manageable toxicity and showed encouraging activity as second-line treatment of advanced or metastatic pancreatic cancer patients with ECOG performance status 0-2.

Mirror Image Gerbode or Partial Atrioventricular Canal Defect?

Cem Ariturk, Ass.Prof.,Ahmet Umit Gullu, Ass.Prof.,Sahin Senay, Ass.Prof.,Eyup Murat Okten, M.D.,Fevzi Toraman,E. Hasan Karabulut, Prof.,Letisya Melengic, M.S.,Cem Alhan, Prof. 대한흉부외과학회 2015 Journal of Chest Surgery (J Chest Surg) Vol.48 No.6

Gebode defect, that can accurately be treated surgical repair, is defined as a true communication between left ventricle and right atrium. A 74-year-old woman with a worsening history of ortophnea and peripheral edema was hospitalised. A communication between right atrium and left ventricle was diagnosed using transeusophageal echocardiography. The defect was repaired and mitral valve was replaced with a biologic valve. It would be beter to tailor surgical strategy for each case with atrioventricular canal defect after preoperative transeusophageal echocardiography and peroperative direct sight.
