이 글은 1999년 5월 13일~15일에 이스탄불의 보스포루스 대학교 (Boğaziçi Üniversitesi)에서 열린 제 13회 (터키) 언어학 회의에서 “Türkçe’de kaynaştırma sesleri [터키어의 연결음들]”이라는 제목으로 발표되어 2000년에 이스탄불에서 A. Sumru Özsoy 및 Eser E. Taylan의 편집으로 다른 발표문들과 함께 XIII. Dilbilim Kurultay Bildirileri, 13.~15. Mayıs 1999, Boğaziçi Üniversitesi [제13회 언어학 회의 발표문들, 1999년 5월 13일~15일, 보스포루스 대학교]라는 책으로 발간된 Talât Tekin의 글 (pp. 109-112)을 우리말로 옮긴 것이다. 이 글에서 다루지 않은 것으로, 자음으로 끝나는 낱말들에 자음으로 시작되는 접미사가 이어질 때에 두 자음 사이에 들어가는 연결 모음 /ï, i, u, ü/가 있다. 이들 모음은 대개 접미사의 일부로 간주된다: baba-m “나의 아버지”, 그러나 ev-i-m “나의 집”; ütü-n “너의 다리미”, 그러나 göz-ü-n “너의 눈”; şemsiye-miz “우리의 우산”, 그러나 kız-ı-mız “우리의 딸”; rüya-nız “너희/당신의 꿈”, 그러나 yol-u-nuz “너희/당신의 길”; oku-t- “읽히다, 공부시키다”, söyle-ş- “함께/서로 말하다, yıka-n- “씻기다; 자기 몸을 씻다”, 그러나 ak-ı-t- “흘리다, 흐르게 하다”, böl-ü-n- “나뉘다”, kes-i-l- “잘리다”, vur-u-ş- “서로 치다, 때리다, 싸우다” 등등. One of the phonological phenomena that the linguists and grammarians of Turkey have difficulty in explaining is the appearance of consonants /y, n, s, ş/ between the final vowel of a word and the initial vowel of the suffix. In Turkic languages and dialects, the only gap-filling sound between two vowels is /y/. The consonant /s/ appearing between the final vowel of a word and the third person possessive suffix {-I} might be a plural suffix by origin; {-sI} has been regarded later through syllabication and false analysis as the variant of the third person possessive suffix {-I} after a vowel. The variant {-şAr} after a vowel of the distributive suffix was also fixed through syllabication and false analysis. The consonant /n/ in the declension of the demonstrative pronouns and in the declension of words with the third person possessive suffix was originally the final sound dropped in the nominative case. The consonant /n/ after a vowel in the genitive case was fixed through syllabication and false analysis. The consonant /n/ in the declension of words with the suffix {-ki} is presumably a part of that suffix. The consonant /n/ in the declension of kendi is the result of an false analysis.

A rapid and direct method for half value layer calculations for nuclear safety studies using MCNPX Monte Carlo code

Tekin H.O.,ALMisned Ghada,Issa Shams A.M.,Zakaly Hesham M.H. 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.9

Half Value Layer calculations theoretically need prior specification of linear attenuation calculations, since the HVL value is derived by dividing ln(2) by the linear attenuation coefficient. The purpose of this study was to establish a direct computational model for determining HVL, a vital parameter in nuclear radiation safety studies and shielding material design. Accordingly, a typical gamma-ray transmission setup has been modeled using MCNPX (version 2.4.0) general-purpose Monte Carlo code. The MCNPX code's INPUT file was designed with two detection locations for primary and secondary gamma-rays, as well as attenuator material between those detectors. Next, Half Value Layer values of some well-known gamma-ray shielding materials such as lead and ordinary concrete have been calculated throughout a broad gamma-ray energy range. The outcomes were then compared to data from the National Institute of Standards and Technology. The Half Value Layer values obtained from MCNPX were reported to be highly compatible with the HVL values obtained from the NIST standard database. Our results indicate that the developed INPUT file may be utilized for direct computations of Half Value Layer values for nuclear safety assessments as well as medical radiation applications. In conclusion, advanced simulation methods such as the Monte Carlo code are very powerful and useful instruments that should be considered for daily radiation safety measures. The modeled MCNPX input file will be provided to the scientific community upon reasonable request.

X-ray CT monitoring of macro void development in mortars exposed to sulfate attack

Ilker Tekin,Recep Birgul,Huseyin Y. Aruntas 사단법인 한국계산역학회 2018 Computers and Concrete, An International Journal Vol.21 No.4

This study reports the results of nondestructive monitoring of macro void developments in mortars manufactured with both ordinary Portland cement and sulfate resistant cement. Two types of curing were utilized; tap water curing and another curing environment that contains 5% Na2(SO4) solution. Being the primary objective of this study, macro void developments of the mortar specimens were monitored by X-ray Medical Computerized Tomography. Compressive strength tests and water absorption tests were conducted on specimens that were kept in both curing environments for a duration of 560 days. Data analyses yielded consistent results among the three tests used in this experimental study. Macro void ratios of mortars decreased at the beginning of experiments for a certain period; afterwards, macro void ratios increased. The objective of this study was accomplished as anticipated since X-CT image analysis was able to nondestructively monitor macro void development process in cement mortars.

Limit point instability of shallow arches under localized sinusoidal loading

Ayfer Tekin Atacan 국제구조공학회 2023 Structural Engineering and Mechanics, An Int'l Jou Vol.85 No.5

In the present study, the limit point buckling and postbuckling behaviors of sinusoidal, shallow arches with pinned supports subjected to localized sinusoidal loading, based on the Euler-Bernoulli beam theory, are numerically analyzed. There are some studies on the buckling of sinusoidal shallow arches under the effect of sinusoidal loading. However, in these studies, the sinusoidal loading acts along the horizontal projection of the entire shallow arch. No study has been found in the relevant literature pertaining to the stability of the shallow arches subjected to various lengths of sinusoidal loading. Therefore, the purpose of this paper is to contribute to the literature by examining the effect of the length of the localized sinusoidal loading and the initial rise of the shallow arch on the limit point buckling and postbuckling behaviors. Equilibrium paths corresponding to certain values of the length of the localized sinusoidal loading and various values of the initial rise parameter are presented. It has been observed that the length of the sinusoidal loading and the initial rise parameter affects the transition from no buckling to limit point instability remarkably. The deformed configurations of the sinusoidal shallow arch under localized loading regarding buckling and postbuckling states are illustrated, as well. The effects of the length of the localized sinusoidal loading on the internal forces of the shallow arch are investigated during various stages of the loading.

HYPERBOLIC TYPE CONVEXITY AND SOME NEW INEQUALITIES

Toplu, Tekin,Iscan, Imdat,Kadakal, Mahir The Honam Mathematical Society 2020 호남수학학술지 Vol.42 No.2

In this paper, we introduce and study the concept of hyperbolic type convexity functions and their some algebraic properties. We obtain Hermite-Hadamard type inequalities for this class of functions. In addition, we obtain some refinements of the Hermite-Hadamard inequality for functions whose first derivative in absolute value, raised to a certain power which is greater than one, respectively at least one, is hyperbolic convexity. Moreover, we compare the results obtained with both Hölder, Hölder-İşcan inequalities and power-mean, improved-power-mean integral inequalities.

Ali Tekin,Murat Pehlivan,Sibel Tiryaki,Ömer Barış Yücel,Uygar Bağcı,Hasan Çayırlı,İlker Zeki Arusoğlu,İbrahim Ulman 대한배뇨장애요실금학회 2022 International Neurourology Journal Vol.26 No.4

Purpose: Perineal electromyography (EMG) is a crucial part of urodynamic studies. Many researchers focused on the standardization of techniques in urodynamics, but no study has yet evaluated the differences with various reference electrode placements. The aim of this study was to determine the optimal placement of the reference electrode for recording pelvic floor activity in urodynamic studies. Methods: Children over 6 years of age without anatomic or neurological abnormalities were invited to participate in the study. Four reference electrodes were placed on the right kneecap, the inner surface of the right inner thigh, the right anterior iliac spine (AIS), and the skin over the left gluteal muscles for simultaneous recording. The EMG signal formed by pelvic contraction during forceful straining was recorded both in the supine and sitting positions. The root mean square (RMS) value of each muscle contraction signal was calculated. Results: Twenty-one participants (10 boys and 11 girls) were included. The mean age was 10.19±3.20 years. The highest RMS values were obtained with the reference electrode on the thigh in the supine position and the AIS in the sitting position. Significant differences were found between the mean RMS values of the knee and other locations of reference electrodes in the supine position, as well as between mean RMS values in all regions except the thigh and gluteus in the sitting position. The minimum mean RMS values in both positions were obtained with the reference electrode on the knee. Conclusions: During urodynamic studies, reference electrodes shall be placed on AIS in the sitting and on the inner thigh in the supine position. The knee is not a suitable option for reference electrode placement. This information may help improve EMG recordings in the evaluation of pelvic floor muscles.

Objective: Antiepileptic drugs (AED) have chronic teratogenic effects, the most common of which are congenital heart disease, cleft lip/palate, urogenital and neural tube defects. The aim of our study is to examine teratogenic effects of AED and the correlation between these malformations and AED in single or multiple pregnancies. Methods: This is a retrospective study of malformations in children born to mothers currently followed up by our outpatient clinics who used or discontinued AED during their pregnancy. Their children were then investigated using echocardiography, urinary ultrasound, cranial magnetic resonance image, and examined by geneticists and pediatric dentists. Results: One hundred and seventeen children were included in the study. Ninety one of these children were exposed to AED during pregnancy. The most commonly used AED were valproic acid and carbamazepine in monotherapy. The percentage of major anomaly was 6.8% in all children. Dysmorphic features and dental anomalies were observed more in children exposed especially to valproic acid. There were 26 mothers with two and four mothers with three pregnancies from the same fathers. No correlation was found between the distribution of malformations in recurring pregnancies and AED usage. Conclusion: Our study has the highest number of dysmorphism examined in literature, found in all the children exposed to valproic acid, which may account for the higher rate of facial dysmorphism and dental anomalies. On lower doses of valproic acid, major malformations are not seen, although the risk increases with polytherapy. Our data also indicate possible effects of genetic and environmental factors on malformations.
