Citak, Ebru Akgun,Toruner, Ebru Kilicarslan,Gunes, Nebahat Bora Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.9

Background: Communication plays an important role for the well being of patients, families and also health care professionals in cancer care. Conversely, ineffective communication may cause depression, increased anxiety, hopelessness and decreased of quality life for patients, families and also nurses. Objective: This study aimed to explore communication difficulties of pediatric hematology/oncology nurses with patients and their families, as well as their suggestions about communication difficulties. Materials and Methods: It was conducted in a pediatric hematology/oncology hospital in Ankara, Turkey. Qualitative data were collected by focus groups, with 21 pediatric hematology/oncology nursing staff from three groups. Content analysis was used for data analysis. Results: Findings were grouped in three main categories. The first category concerned communication difficulties, assessing problems in responding to questions, ineffective communication and conflicts with the patient's families. The second was about the effects of communication difficulties on nurses and the last main category involved suggestions for empowering nurses with communication difficulties, the theme being related to institutional issues. Conclusions: Nurses experience communication difficulties with children and their families during long hospital stays. Communication difficulties particularly increase during crisis periods, like at the time of first diagnosis, relapse, the terminal stage or on days with special meaning such as holidays. The results obtained indicate that pediatric nurses and the child/family need to be supported, especially during crisis periods. Feeling of empowerment in communication will improve the quality of care by reducing the feelings of exhaustion and incompetence in nurses.

Purpose: Food allergy (FA) affects the daily lives of children and parents in varying degrees. The Food Allergy Quality of Life Questionnaire-Parent Form (FAQLQ-PF) is a valid and reliable instrument to assess the quality of life (QoL) of children from parents’ perception. The aim of this study was to validate and determine the reliability of the Turkish FAQLQ-PF and to assess QoL in food-allergic children. Methods: Children aged between 0 and 12 years and diagnosed with immunoglobulin E (IgE)-mediated FA for at least 1 month were enrolled. The English FAQLQ-PF was translated into Turkish according to the World Health Organization guidelines. The Food Allergy Independent Measure and the Turkish Child Health Questionnaire- Parent Form 50 were used for construct validity. Results: One hundred and fifty-seven patients participated. The median age of patients and FA duration were 2.4 years (1.2-5.2 years, interquartile-ranges) and 2 years (0.8-5.1), respectively. Ninety-six (61.1%) patients had anaphylaxis. The Cronbach’s alpha coefficient and intra-class correlation coefficient for test-retest reliability was good for all age groups of children (< 4, 4-6, and 7-12 years). Patients with either asthma or anaphylaxis had worse scores than others. Total scores of FAQLQ-PF tended to increase with age. Patients aged 7-12 had the highest total scores among all patients (2.2±0.1, 3.0±0.2, and 3.3±0.3 for < 4, 4-6, and 7-12 years, respectively, P < 0.001, P for trend < 0.001). Other factors causing the poor QoL were cow’s milk allergy, sibling allergy, mother’s age over 30 years, mother’s high education level and lower number of persons in household. Conclusions: The Turkish FAQLQ-PF is a valid and reliable scale. FA-related QoL was significantly worse with age. Coexistent asthma, anaphylaxis regardless of its severity, cow’s milk allergy, sibling allergy and the older and educated mothers seem to poorly affect QoL.

Stochastic analysis of fluid-structure interaction systems by Lagrangian approach

Ebru Hançer,Alemdar Bayraktar 국제구조공학회 2005 Structural Engineering and Mechanics, An Int'l Jou Vol.20 No.4

In the present paper it is aimed to perform the stochastic dynamic analysis of fluid and fluidstructure systems by using the Lagrangian approach. For that reason, variable-number-nodes twodimensional isoparametric fluid finite elements are programmed in Fortran language by the authors and incorporated into a general-purpose computer program for stochastic dynamic analysis of structure systems, STOCAL. Formulation of the fluid elements includes the effects of compressible wave propagation and surface sloshing motion. For numerical example a rigid fluid tank and a dam-reservoir interaction system are selected and modeled by finite element method. Results obtained from the modal analysis are compared with the results of the analytical and numerical solutions. The Pacoima Dam record S16E component recorded during the San Fernando Earthquake in 1971 is used as a ground motion. The mean of maximum values of displacements and hydrodynamic pressures are compared with the deterministic analysis results.

Arising Risks in Urban Settlements: How Can Urban Settlements Be Made Disaster-Resilient in Light of Increasingly Devastating Natural Disasters over the Last Decade?

Ebru Alarslan 서울시립대학교 도시과학연구원 2008 도시과학국제저널 Vol.12 No.1

This paper outlines possible approaches towards disaster mitigation in light of increasingly devastating effects of natural disasters especially over the last decade. The hazards of natural disasters are more significant in urban settlements than other areas due to their denser populations, constructions, and service networks. Against this background, this paper is based on my pending doctoral dissertation which proposes a disaster-resilient urban settlement guidebook. In addition, this paper reflects the preliminary findings of the dissertation on disaster threats and resilient methods for urban settlements. Despite the existence of various types of natural disasters such as earthquakes, floods, landslides, and avalanches, the proposed guidebook for disaster-resilient urban settlements is derived from the dynamics of earthquakes. It will suggest different approaches for developing and/or rapidly increasing population countries and developed countries, respectively. A comparative case study was conducted in Yalova, Turkey and Cologne, Germany as representative cities of rapidly increasing population countries and developed countries. These two cities were also selected because they have high seismic risks and somewhat similar settlement profiles (e.g., both of them are coastal cities with similar population figures and industrial growth).

In recent years, natural products gained popularity with their anti-inflammatory and antioxidant effects mediated by chemical compounds within their composition. Study results offering them as palliative therapy options in cancer or as anticancer agents with high levels of cytotoxicity brought a new approach to combine cancer treatment protocols with these products. From a different perspective, edible types of these products are suggested in daily diets due to their potential cancer preventive effects. Our preliminary work was on blueberry extracts (Vaccinium myrtillus) as a main representative of these natural products, and the contents of the extracts were analyzed with liquid chromatography tandem mass spectrometry (LC MS/MS) to reveal the composition and distribution of polyphenolic compounds within. The most abundant polyphenols detected in V. myrtillus extracts were quercetin, kaempferol, and a phenolic acid, gentisic acid (GA). The compounds were further evaluated on treated HCT-116 cells for their potential anticancer effects by measuring total antioxidant status, total oxidant status, and 8-hydroxydeoxyguanosine levels for evaluation of oxidative stress and through protein array analysis and flow cytometric analysis for evaluation of apoptosis. In analysis of oxidative stress parameters, reduced total oxidant levels and reduced oxidative stress index levels were found in cells treated with the compounds in comparison with untreated cells. In apoptosis-related protein profiles, at least twofold reduction in various apoptotic proteins was observed after quercetin and kaempferol treatment, whereas a different profile was observed for GA. Overall, results of this study showed that quercetin and kaempferol have strong cytotoxic, antioxidant, and apoptotic effects, although GA is mostly effective as an antioxidant polyphenol on HCT-116 cells.

Selective and synergistic extraction of cadmium from acidic iodine solutions containing Cd2+, Co2+ and Ni2+using solvent extraction (SX) technique is presented in this study. The study has highlighted the importance of main and synergistic extractants composition. The mixtures have evident synergistic effects on Cd2+ with a synergistic enhancement factor of 2.22. The various experimental parameters were studied to determine the optimum extraction and stripping conditions of Cd2+. Under optimum conditions, the maximum extraction efficiency (99.7%) was achieved when using 1.5% (v/v) TIOA and 0.5%(v/v) TBP in dichloromethane within 5 min. Extracted Cd2+ was stripped effectively from the organic phase using 2.0 mol/L NaOH solution.

Korean adverbial particle -(u)lo , L2 acquisition, particle development process, L1 English learners

( Ebru Turker ) 한국문법교육학회 2017 문법 교육 Vol.31 No.-

This study investigates the acquisition of the multiple meanings of the Korean adverbial particle -(u)lo by L1 American English learners of Korean-as-a-foreign-language studying at U.S. institutions. Beginning, intermediate, and advanced proficiency level learners (N=45) participated in two types of tasks to determine their ability to interpret and produce six meanings of -(u)lo, to which they had been exposed in formal classroom settings. The results indicate different developmental trajectories with respect to different meanings of the particle. The findings of a statistical analysis show that only the transportation meaning of -(u)lo had been acquired by all levels. The intermediate level participants’ performance on the raw material, instrumental, and directional meanings was better than the beginning level participants’ performance, and the advanced level participants demonstrated nearly full acquisition of these four meanings (i.e. transportation, raw material, instrumental, and directional). All groups showed low rates of acquisition for the reason and option meanings. The study suggests that the acquisition and development of the meanings of -(u)lo are affected by cross-linguistic influence, semantic complexity, the availability of linguistic input, and the possibility of particle alternation.

Investigation of earthquake angle effect on the seismic performance of steel bridges

Ebru Kalkan,Ahmet C. Altunışık 국제구조공학회 2016 Steel and Composite Structures, An International J Vol.22 No.4

In this paper, it is aimed to evaluate the earthquake angle influence on the seismic performance of steel highway bridges. Upper-deck steel highway bridge, which has arch type load bearing system with a total length of 216 m, has been selected as an application and analyzed using finite element methods. The bridge is subjected to 1992 Erzincan earthquake ground motion components in nineteen directions whose values range between 0 to 90 degrees, with an increment of 5 degrees. The seismic weight is calculated using full dead load plus 30% of live load. The variation of maximum displacements in each directions and internal forces such as axial forces, shear forces and bending moments for bridge arch and deck are attained to determine the earthquake angle influence on the seismic performance. The results show that angle of seismic input motion considerably influences the response of the bridge. It is seen that maximum arch displacements are obtained at X, Y and Z direction for 0°, 65° and 5°, respectively. The results are changed considerably with the different earthquake angle. The maximum differences are calculated as 57.06%, 114.4% and 55.71% for X, Y and Z directions, respectively. The maximum axial forces, shear forces and bending moments are obtained for bridge arch at 90°, 5° and 0°, respectively. The maximum differences are calculated as 49.12%, 37.37% and 51.50%, respectively. The maximum shear forces and bending moments are obtained for bridge deck at 0°. The maximum differences are calculated as 49.67%, and 49.15%, respectively. It is seen from the study that the variation of earthquake angle effect the structural performance of highway bridges considerably. But, there is not any specific earthquake angle of incidence for each structures or members which increases the value of internal forces of all structural members together. Each member gets its maximum value of in a specific angle of incidence.

A Quantitative Analysis of Anger and Happiness Metaphors in Korean across Genres and over Time

Ebru Turker 담화·인지언어학회 2022 담화와 인지 Vol.29 No.3

This quantitative study takes a data-driven corpus-based approach to variation in the use of Korean emotion metaphors across modern written genres and over time (1980–2004). It focuses on two sets of semantically close emotion words, hwa and pwunno (similar to anger and rage, respectively) in figurative expressions based on anger metaphors, and hayngpok and kippum (similar to happiness and joy, respectively) in figurative expressions based on happiness metaphors. The results demonstrate that both genre and year affect the frequency of occurrence of figurative expressions. For anger, hwa metaphors are more frequent in the nonfiction book and novel genres than other genres, while pwunno metaphors show no difference by genre. Hwa metaphors occur consistently and at high frequencies across the time period analyzed, while pwunno metaphors show up later and at lower frequencies. For happiness, kippum metaphors are more frequent in the nonfiction book and newspaper genres, while hayngpok occurs most frequently in the nonfiction book and novel genres. The frequency distributions of expressions with hayngpok and kippum changed over the years in different ways, with short, reversed rises and falls. The paper concludes by discussing the benefits and limitations of a corpus-based genre approach to the study of figurative language.

PREDICTIONS OF CRITICAL HEAT FLUX USING THE ASSERT-PV SUBCHANNEL CODE FOR A CANFLEX VARIANT BUNDLE

EBRU NIHAN ONDER,,LAURENCE KIM-HUNG LEUNG,YANFEI RAO 한국원자력학회 2009 Nuclear Engineering and Technology Vol.41 No.7

The ASSERT-PV subchannel code developed by AECL has been applied as a design-assist tool to the advanced CANDU®1 reactor fuel bundle. Based primarily on the CANFLEX®2 fuel bundle, several geometry changes (such as element sizes and pitchcircle diameters of various element rings) were examined to optimize the dryout power and pressure-drop performances of the new fuel bundle. An experiment was performed to obtain dryout power measurements for verification of the ASSERT-PV code predictions. It was carried out using an electrically heated, Refrigerant-134a cooled, fuel bundle string simulator. The axial power profile of the simulator was uniform, while the radial power profile of the element rings was varied simulating profiles in bundles with various fuel compositions and burn-ups. Dryout power measurements are predicted closely using the ASSERT-PV code, particularly at low flows and low pressures, but are overpredicted at high flows and high pressures. The majority of data shows that dryout powers are underpredicted at low inlet-fluid temperatures but overpredicted at high inlet-fluid temperatures.
