( Irem Eren Erturk ),( Ozer Arican ),( Imran Kurt Omurlu ),( Necdet Sut ) 대한피부과학회 2012 Annals of Dermatology Vol.24 No.4

Background: Pruritus affects the quality of life (QoL) in the patients. However, little is known of the impacts of itching on the QoL in the literature. Objective: In this study, a questionnaire eliciting specific responses about pruritus was used to determine the effect of itching and its severity on QoL in chronic pruritic patients. Methods: One hundred ten adult patients with chronic pruritus were surveyed. Once itch severity had been self-reported by patients, together with Skindex-29, they have been given the 18-item Pruritus- related Life Quality Index (PLQI) questionnaire, which was used to generated the new index. Results: Significant correlations have been found between the pruritus severity score of participants and their total Skindex-29 (p<0.001) with its function, emotion and symptom subscale scores (p <0.001 for each). Also, significant correlations were evident between total PLQI (p<0.001) and its psychosocial negativities, difficulties in everyday activities and social live subscale scores (p<0.001 for each). In particular, the emotion subscale of Skindex-29 (p=0.02) and psychosocial negativity subscale of PLQI (p=0.02) were significantly high in psychopathologic patients. A highly positive statistical correlation between Skindex-29 and PLQI scales was evident (r=0.845, p<0.001). For reliability, Cronbach`s coefficient a coefficients were 0.931 for the Skindex-29 scale and 0.918 for the PLQI scale. Conclusion: The results demonstrate that chronic pruritus appreciably reduces the QoL. PLQI could be used in the development of new questionnaires for determining the QoL of patients with chronic itch. (Ann Dermatol 24(4) 406∼412, 2012)

Irem Eren-Erdogmus,Emine Cobanoglu,Isil Budeyri-Turan 한국마케팅과학회 2015 Journal of Global Fashion Marketing Vol.6 No.2

Successful apparel brand management calls for crafting brand imagery, such as brandpersonality, around the apparel brand. Building a brand personality around the apparelbrand is one way to form an attachment between consumers and the brands they choose towear on the grounds of self-identification. The aim of this study is to explore theapplicability of Aaker’s (1997) brand personality dimensions to apparel brands forGeneration Y in Turkey, one third of whose population belongs to this generation. Generation Y consumers posit a profitable target market for apparel brands, based on thesize of the group and its apparel consumption. The findings of the study confirm thewidely accepted brand personality dimensions of sincerity, excitement, competence andsophistication. Ruggedness, on the other hand, was not extracted, probably dueGeneration Y’s postmodern way of life. The study found a new apparel brand personalitydimension, uniqueness, which might be elaborated in detail in future studies. Anotherdimension that appeared in this study was traditionalism, which confirmed previousbrand personality studies in Turkey. Implications for apparel brand managers areprovided in terms of how to communicate their brand personality alternatives toGeneration Y through conducting various marketing mix activities.

Irem Ayaz,Eman Shaheen,Medhat Aly,Sohaib Shujaat,Giulia Gallo,Wim Coucke,Constantinus Politis,Reinhilde Jacobs 대한영상치의학회 2020 Imaging Science in Dentistry Vol.50 No.1

Purpose: This study was conducted to objectively and subjectively compare the accuracy and reliability of 2-dimensional (2D) photography and 3-dimensional (3D) soft tissue imaging. Materials and Methods: Facial images of 50 volunteers (25 males, 25 females) were captured with a Nikon D800 2D camera (Nikon Corporation, Tokyo, Japan), 3D stereophotogrammetry (SPG), and laser scanning (LS). All subjects were imaged in a relaxed, closed-mouth position with a normal smile. The 2D images were then exported to Mirror® Software (Canfield Scientific, Inc, NJ, USA) and the 3D images into Proplan CMF® software (version 2.1, Materialise HQ, Leuven, Belgium) for further evaluation. For an objective evaluation, 2 observers identified soft tissue landmarks and performed linear measurements on subjects’ faces (direct measurements) and both linear and angular measurements on all images (indirect measurements). For a qualitative analysis, 10 dental observers and an expert in facial imaging (subjective gold standard) completed a questionnaire regarding facial characteristics. The reliability of the quantitative data was evaluated using intraclass correlation coefficients, whereas the Fleiss kappa was calculated for qualitative data. Results: Linear and angular measurements carried out on 2D and 3D images showed excellent inter-observer and intra-observer reliability. The 2D photographs displayed the highest combined total error for linear measurements. SPG performed better than LS, with borderline significance (P=0.052). The qualitative assessment showed no significant differences among the 2D and 3D imaging modalities. Conclusion: SPG was found to a reliable and accurate tool for the morphological evaluation of soft tissue in comparison to 2D imaging and laser scanning.

Effect of Packaging Methods on Colour, Lipid Quality and Microbial Growth of Beef Patties Enhanced with Flaxseed Flour

Irem Altuntas,Sadettin Turhan 한국축산식품학회 2013 한국축산식품학회지 Vol.33 No.1

In this study, the effect of packaging methods [aerobic packaging (AP), vacuum packaging (VP) and modified atmosphere packaging (MAP: 75% N2, 25% CO2)] on colour, lipid quality and microbial growth of beef patties enhanced with flaxseed flour was investigated during storage at 2±1ºC for 10 d. L and a values of beef patties packaged in MAP and VP were higher (p<0.05) than that of the samples packaged in AP. Packaging in MAP and VP retarded the lipid oxidation (TBA value) and inhibited the bacterial growth of beef patties enhanced with flaxseed flour. Furthermore, TBA values in beef patties were correlated with a values (r = -0.340; p<0.05). Packaging in MAP was more effective than packaging in VP for inhibiting microbial growth. The samples packaged in VP lost their shape due to the compression by external atmosphere. Packaging treatment had no significant effect on saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) levels in beef patties. The a and b, TBA and MUFA values changed during storage time. TBA values for beef patties increased during storage time, but did not reach to the limit value (1 mg/kg) until the end of the storage time. The results suggest that the shelf life of beef patties enhanced with flaxseed flour can be extended by packaging in MAP.

OBSERVATIONS ON IDENTITIES AND RELATIONS FOR INTERPOLATION FUNCTIONS AND SPECIAL NUMBERS

Irem Kucukoglu,Yilmaz Simsek 장전수학회 2018 Advanced Studies in Contemporary Mathematics Vol.28 No.1

The main motivation of this paper is to study and inves- tigate a new family of combinatorial numbers with their generating functions. Firstly, we obtain some finite series representations includ- ing well-known numbers such as the Apostol-Bernoulli numbers, the Apostol-Euler numbers, a family of combinatorial numbers, the Daehee numbers, the Changhee numbers and the Stirling numbers of the second kind. Secondly, applying Mellin transform to these functions, we give interpolation functions for these numbers. We investigate some proper- ties of these functions and other related complex valued functions. We observe that some special values of these functions give us the terms of some well-known infinite series. Thus, these functions unify the terms of some well-known identities and functions such as Hasse identity, the polylogarithm function, the digamma function, the Riemann zeta func- tions, the alternating Riemann zeta function, the Hurwitz zeta function, the alternating Hurwitz zeta function, the Hurwitz-Lerch zeta function and the other functions. Moreover, we give some remarks and observa- tions about these functions related to some special numbers and poly- nomials such as the Stirling numbers of the second kind, the harmonic numbers, the array polynomials and also related to hypergeometric func- tions, the family of zeta functions. We also give not only Riemann inte- gral representation, but also Cauchy integral representations for this new family of combinatorial numbers. Finally, in order to compute numerical values of these interpolation functions and other related complex valued functions, we present two algorithms. Furthermore, by using these al- gorithms, we provide some plots of these functions. Also, we investigate the effects of their parameters.

IREM KUCUKOGLU,YILMAZ SIMSEK 장전수학회 2018 Advanced Studies in Contemporary Mathematics Vol.28 No.4

In this paper, by differentiating the generating functions for one of the family of the Apostol-type numbers and polynomials with re- spect to their parameters, we present some partial differential equations including these functions. By making use of these equations, we provide some new formulas, relations and identities including these numbers and polynomials and their derivatives. Furthermore, by using a col- lection of the generating functions for the aforementioned family and their functional equations, we investigate the numbers and polynomials belonging to this family and their relationships with other well-known special numbers and polynomials including the Apostol-Bernoulli num- bers and polynomials of higher order, the Apostol-Euler numbers and polynomials of higher order, the Frobenius-Euler numbers and polyno- mials of higher order, the λ-array polynomials, the λ-Stirling numbers, and the λ-Bernoulli numbers and polynomials.

SOME RELATIONSHIPS BETWEEN THE NUMBERS OF LYNDON WORDS AND A CERTAIN CLASS OF COMBINATORIAL NUMBERS CONTAINING POWERS OF BINOMIAL COEFFICIENTS

IREM KUCUKOGLU 장전수학회 2020 Advanced Studies in Contemporary Mathematics Vol.30 No.4

The main aim of this paper is to nd out some relationships between the numbers of Lyndon words and a certain class of combinatorial numbers which contains nite sums of powers of binomial coecients and whose generating functions were constructed and investigated by Simsek in \Generating functions for nite sums involving higher powers of binomial coecients: Analysis of hypergeometric functions including new families of polynomials and numbers, J. Math. Anal. Appl. 477 (2019), 1328{1352". By applying not only the Dirichlet convolution formula, but also the Mobius inversion formula, we obtain some identities containing the Mobius function, the Euler's totient function, the numbers of Lyndon words, the numbers of necklaces, the Stirling numbers of the second kind, and the aforementioned class of combinatorial numbers. Moreover, a few special cases and consequences of our results are considered. In particular, it should be noted here that in the special case when we take the power of the binomial coecients to be 1, some of our results are reduced to several results obtained by Kucukoglu and Simsek in \Identities and Derivative Formulas for the Combinatorial and Apostol-Euler Type Numbers by Their Generating Functions, Filomat 32(20) (2018), 6879{6891".

Irem Kucukoglu,Yilmaz Simsek 대한수학회 2019 대한수학회지 Vol.56 No.1

The main purpose of this paper is to investigate the $q$-Apostol type Frobenius-Euler numbers and polynomials. By using generating functions for these numbers and polynomials, we derive some alternative summation formulas including powers of consecutive $q$-integers. By using infinite series representation for $q$-Apostol type Frobenius-Euler numbers and polynomials including their interpolation functions, we not only give some identities and relations for these numbers and polynomials, but also define generating functions for new numbers and polynomials. Further we give remarks and observations on generating functions for these new numbers and polynomials. By using these generating functions, we derive recurrence relations and finite sums related to these numbers and polynomials. Moreover, by applying higher-order derivative to these generating functions, we derive some new formulas including the Hurwitz--Lerch zeta function, the Apostol-Bernoulli numbers and the Apostol-Euler numbers. Finally, for an application of the generating functions, we derive a multiplication formula, which is very important property in the theories of normalized polynomials and Dedekind type sums.

Background: Metabolic syndrome is a systemic disorder and manifests a group of conditions such as abdominal obesity, dyslipidaemia, hypertension, coronary artery diseases. The importance of epicardial adipose tissue recognized its contribution to inflammation by pro-inflammatory cytokines discharge has been proved. Several investigations were performed on vitamin D receptor in different tissues except bone. In this study the epicardial adipose tissue thickness (EATT) and the levels of vitamin D were measured and compared with healthy control group. Methods: A total of 148 patients (84 patients who had metabolic syndrome without diabetes and 64 healthy individuals) were enrolled into the study. In all patients, the EATT was calculated by ecocardiography and the level of serum 25(OH) vitamin D was monitored. Results: It has been observed that the EATT in patients with metabolic syndrome increases significiantly compared with healthy control group (p<0.001). No significant difference between patients and control group was found on the levels of 25 (OH) vitamin D (p=0.507). There was no correlation between 25 (OH) vitamin D and the EATT (p=0.622). Conclusion: We observed that the EATT increased in patients with metabolic syndrome. In contradiction to the literature; the levels of 25(OH) vitamin D has not been found high in patients with metabolic syndrome. The reason of this can be small number of patients in our study. A significant correlation was not found between the EATT and the levels of 25 (OH) vitamin D. Further studies with a larger patient population are required assess the relationship.
