Background: The aim of this study was to determine beliefs concerning breast self-examination in first- and second-degree relatives of patients with breast cancer and evaluate their breast self-examination (BSE) application. Materials and Methods: A survey study was conducted in an oncology polyclinic and general surgery clinic of a hospital in Ankara, the capital of Turkey with a sample of 140 women. Results: It was determined that 60.7% of the participants had conducted BSE and 48.1% had undergone a clinical breast examination. Perceived selfefficacy of the women who performed BSE were significantly higher compared with women who did not practice BSE (p<0.001) Furthermore, perceived barriers were lower among those who had performed BSE (p<0.001). Logistic regression analysis indicated that women who perceived higher self-efficacy (OR: 1.119, 95% CI: 1.056-1.185, p<0.001) and had regular CBE (OR: 8.250, 95% CI: 3.140-21.884, p<0.001) and educational status (OR: 5.287, 95% CI: 1.480-18.880, p<0.01) were more likely to perform BSE. Conclusions: Findings from this study indicated that perceived barriers, perceived self-efficacy, and educational status could be predictors of BSE behavior among the first- and second-degree relatives of patients with breast cancer. Therefore, BSE training programs that emphasize self-efficacy and address perceived barriers are recommended.

<P><B>Abstract</B></P> <P>The fiber-shaped supercapacitor is a promising energy storage device in wearable and portable electronics because of its high flexibility, small size, and light weight. However, most of the reported fiber-shaped supercapacitors have exhibited low capacitance and energy density due to the limited surface area between the two fiber electrodes and operating voltage range. Herein, we successfully developed a coaxial fiber-shaped asymmetric supercapacitor (CFASC) made from MnO<SUB>2</SUB>/CNT-web paper as a cathode coupled with Fe<SUB>2</SUB>O<SUB>3</SUB>/carbon fiber as an anode with a high operating voltage of 2.2 V. The prepared CFASC device showed a high volumetric energy density of 0.43 mWh cm<SUP>−3</SUP> at a power density of 0.02 W cm<SUP>−3</SUP>, which is comparable to those of previously reported fiber-shaped supercapacitors. Additionally, CFASC exhibited good rate capability, long cycle life, and high volumetric capacitance (0.67 F cm<SUP>−3</SUP>) with excellent flexibility. The promising performance of CFASC illustrated its potential for portable and wearable energy storage devices.</P> <P><B>Graphical abstract</B></P> <P>The coaxial fiber-shaped asymmetric supercapacitor (CFASC) was successfully developed by simply wrapping the Fe<SUB>2</SUB>O<SUB>3</SUB>/CFs negative electrode with the PVA-LiClO<SUB>4</SUB> gel electrolyte-coated MnO<SUB>2</SUB>/CNT-web paper positive electrode. This CFASC can be operated at large potential windows up to 2.2 V, resulting in high specific energy, and showed excellent cycling stability and device flexibility.</P> <P>[DISPLAY OMISSION]</P>

<P><B>Abstract</B></P> <P>Thin, lightweight, stackable, solid-state supercapacitors are in great demand in the electronics industry because of their use in miniaturized devices. Herein, we report a simple and novel strategy to fabricate ultra-thin, lightweight, and stackable symmetric supercapacitors using MnO<SUB>2</SUB>-incorporated carbon nanotube (CNT)-web paper. SEM and TEM analyses revealed a uniform nanometer-scale coating of MnO<SUB>2</SUB> on the individual fibers of the CNT-web paper after simple deposition at room temperature. The network structure of free-standing conductive CNT-web paper provides a short diffusion path, allowing for complete utilization of MnO<SUB>2</SUB> in the charge storage process. A MnO<SUB>2</SUB>/CNT-web paper electrode showed an excellent areal capacitance of 135 mF cm<SUP>−2</SUP> at 5 mV s<SUP>−1</SUP> with a remarkable capacitance retention of 95% after 10,000 cycles. A symmetric solid-state supercapacitor containing MnO<SUB>2</SUB>/CNT-web paper displayed a high areal capacitance of 57 mF cm<SUP>−2</SUP> with an energy density of 0.018 mWh cm<SUP>−2</SUP> and a capacitance retention as high as 86% after 10,000 cycles. In addition, the voltage and capacitance were tripled by simply stacking three symmetric supercapacitors and connecting them in series and in parallel, respectively. We are optimistic that the excellent performance of the ultra-thin CNT-web paper-based supercapacitors demonstrated here will facilitate the development of compact supercapacitor banks in the near future.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Ultra-thin and stackable supercapacitors are fabricated using a simple strategy. </LI> <LI> MnO<SUB>2</SUB>/CNT-web paper electrode shows excellent areal capacitance and life cycle. </LI> <LI> Symmetric supercapacitor is fabricated using the MnO<SUB>2</SUB>/CNT-web paper electrodes. </LI> <LI> Symmetric supercapacitor gives a high areal capacitance of 57 mF cm<SUP>−2</SUP> at 5 mV s<SUP>−1</SUP>. </LI> <LI> Stacked supercapacitors exhibit three-fold higher supercapacitive performance. </LI> </UL> </P>

유성일,Bebi Patil,안희준 한국공업화학회 2019 Journal of Industrial and Engineering Chemistry Vol.71 No.-

Afiber-shaped supercapacitor (FSC) with a unique roll-type configuration is developed by simply rollingpolyaniline-coated carbonfiber bundle electrodes with an H2SO4/polyvinyl alcohol gel electrolyte. Theroll-type polyaniline-coated carbonfibers FSC exhibits four times higher capacitance retention than thetwist-typefiber-shaped supercapacitor and shows an energy density of 2.97 Wh kg 1 at a power densityof 4 kW kg 1, which is almost three orders of magnitude higher than that of the twist-type FSC(0.004 Wh kg 1). The enhanced performance of the roll-type FSC is attributable to its unique roll-typeconfiguration, which creates a short and consistent distance between the electrodes.

Seongil Yu,Bebi Patil,안희준 한국섬유공학회 2020 Fibers and polymers Vol.21 No.3

An asymmetric fiber-shaped supercapacitor (FSC) with roll-type configuration, displaying high power and energydensity characteristics, has been fabricated for energy storage in wearable devices. The positive and negative electrodes of theasymmetric FSC consist of polyaniline (PANI) and MoO3, respectively, and are deposited on a carbon fiber (CF) substrateusing a chemical bath deposition method. A polyvinyl alcohol/H2SO4 gel is used as electrolyte, which also maintains the CFelectrodes in fiber form. The asymmetric PANI//MoO3 roll-type FSC exhibits a wider potential range than its symmetricPANI//PANI counterpart, resulting in higher energy and power densities. The asymmetric PANI//MoO3 roll-type FSC showsan energy density of 67.51 μWh/cm3 with a power density of 59.71 mW/cm3 at a current of 10 mA, which is more than twicethe energy density of symmetric PANI//PANI roll-type FSC (30.42 μWh/cm3 and 25.12 mW/cm3).

Reis, Nesrin,Bebis, Hatice,Kose, Sevinc,Sis, Asli,Engin, Raziye,Yavan, Tulay Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.4

Objective: The aims of this study were to explore Turkish women's knowledge, behavior and beliefs related to cervical cancer and screening. Methods: The study was performed in two cities in the East of Turkey between September 2009 and April 2010, with a sampling group of 387 women. Data were collected by means of an interview form with the Health Belief Model Scale for Cervical Cancer and Pap Smear Test - Turkish Version. Results: Women in the research group were found to have poor knowledge, inadequate health behavior and low/medium level false beliefs regarding cervical cancer screening. There was relation between health beliefs and characteristics of women and particularly education (F = 10.80, p = 0.01). Similarly, it was found that Pap smear barriers were influenced by demographic characteristics and that women with low-level education (p = 0.001), divorced women (p = 0.05), women with low-income(p = 0.05), women who gave their first birth when they were 18 or younger (p = 0.05) and women not applying any contraceptive method at all (p = 0.01) were determined to have negative Pap smear barriers. Conclusions: Primarily the knowledge, attitudes and beliefs of women in the target group should be evaluated to increase their participation in cervical cancer screening and to prepare effective education strategies.

Akpunar, Dercan,Bebis, Hatice,Yavan, Tulay Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.17

Purpose: Research carried out with gynecologic cancer patients using CAM was reviewed to provide a source for discussing which CAM method is used for which purpose, patients' perceptions on the effects/side effects occurred during/after using CAM and their sources of information regarding CAM. Materials and Methods: This literature review was carried out for the period between January 2000 and March 2015 using Scopus, Dynamed, Med-Line, Science Dırect, Ulakbim, Research Starters, Ebscohost, Cinahl Complete, Academic Onefile, Directory of Open Access Journals, BMJ Online Journals (2007-2009), Ovid, Oxford Journal, Proquest Hospital Collection, Springer-Kluwer Link, Taylor & Francis, Up To Date, Web Of Science (Citation Index), Wiley Cochrane-Evidence Base, Wiley Online Library, and Pub-Med search databases with "complementary and alternative medicine, gynecologic cancer" as keywords. After searching through these results, a total of 12 full length papers in English were included. Results: CAM use in gynecologic cancer patients was discussed in 8 studies and CAM use in breast and gynecologic cancer patients in 4. It was determined that the frequency of CAM use varies between 40.3% and 94.7%. As the CAM method, herbal medicines, vitamins/minerals were used most frequently in 8 of the studies. When the reasons why gynecologic cancer patients use CAM are examined, it is determined that they generally use to strengthen the immune system, reduce the side effects of cancer treatment and for physical and psychological relaxation. In this review, most of the gynecologic cancer patients perceived use of CAM as beneficial. Conclusions: In order that the patients obtain adequate reliable information about CAM and avoid practices which may harm the efficiency of medical treatment, it is recommended that "Healthcare Professionals" develop a common language.

Yilmaz, Demet,Bebis, Hatice,Ortabag, Tulay Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.5

Background: Breast cancer is the leading cause of cancer-related deaths in women. Despite being associated with high morbidity and mortality, breast cancer is a disease that can be diagnosed and treated early. Materials and Methods: In this cross-sectional study of 321 women, data were collected by Questionnaire, Breast Cancer Risk Assessment Form and Champion's Health Belief Model Scale. Mann-Whitney U, Kruskal-Wallis, Chisquared tests and logistic regression were used in the statistical analysis. Results: It was found that only 2.2% of women have high and very high risk levels of breast cancer risk. There is a positive correlation between early diagnosis techniques and Health Belief Model Sub-Dimension scores which are sensibility, health motivation, BSE (Breast self-examination) self-efficient perception and negative correlation between mammography barrier score and BSE barrier score (p 0.05). When factors for not having BSE were examined, it was determined that the women who do not have information about breast cancer and the women who smoke have a higher risk of not having BSE. Conclusions: It is important to determine health beliefs and breast cancer risk levels of women to increase the frequency of early diagnosis. Women's health beliefs are thought to be a good guide for planning health education programs for nurses working in this area.
