        『일본서기』 소재 ‘임나 4현 할양’기사의 재해석

        위가야 ( Wee¸ Ka-ya ) 부경역사연구소 2021 지역과 역사 Vol.- No.48

        이 논문은 ‘임나 4현 할양’ 기사에 대한 지금까지의 연구를 점검하여 각각의 異見을 통해 확인된 ‘위치 비정’의 난맥상을 확인한 후, 관점을 달리하는 ‘임나 4현 할양’ 기사 이해를 시도해 보려 한 것이다. 관점을 달리한다는 것은 『일본서기』의 내용에 ‘사실’과 ‘인식’이 섞여 종합적으로 반영되어 있다는 관점에서 접근할 수 있다는 것을 말한다. 이러한 종합적 반영의 결과가 사료의 조작이라면 그 조작 이전의 실체를 검증하고 조작이 배태된 동기를 이해할 때 비로소 사실의 복원이 가능하다는 지적 또한 중시하면서 ‘임나 4현 할양’ 기사를 재해석했다. 이러한 재해석의 결과는 다음과 같다. 『일본서기』에서 大伴金村大連의 실각 원인을 기술하면서 신라 방면에서의 실책이라는 실상에 덧붙여 『일본서기』 편찬 당시의 한반도관에 입각하여 임나의 멸망 또한 大伴氏의 실책에 따른 결과라는 내용을 부가하였다. 이 과정에서 당시 일본에 전해지고 있던 임나 관련 지리적 정보에 의거하여 ‘임나 4현’의 지명이 부가되면서 513년 ‘기문·대사 분쟁’의 전제로서 ‘임나 4현 할양’이라는 가공의 사실이 창출된 것이다. 따라서 관련 지명의 비정을 통해 당시의 역사상을 복원하는 것에는 좀 더 신중을 기할 필요가 있다. This article aims at reviewing the disorder in the “specification of location” identified through different views by examining previous studies on the article “Cession of Imna Four prefectures(任那四縣)”, and comprehending the article interpreted from different perspectives. Different perspectives mean that the content of Nihon Shoki can be approached from the point of view that “facts” and “recognition” are mixed and reflected comprehensively. This article attempts to approach the actuality of the article by placing importance on the comment that if the result of the comprehensive reflection is the falsification of historical records, the fact can be restored only when the substance before being falsified is verified and the motive that bears fabrication is understood. While describing the cause of Ohotomo no Kanamuran Omuraji(大伴金村大 連)’s downfall in Nihon Shoki, in addition to the fact that it was a mistake of Ohotomo in the Silla region, additional content was added. The additional content is that the fall of Imna was also the result of Ohotomo’s mistake, based on the view of the Korean Peninsula at the time of the compilation of Nihon Shoki. The place name of “Imna Four prefectures” was added based on the geographic information related to Imna that was transmitted to Japan at the time, and the historical fact of “Cession of Imna’s Four Prefectures” was created as the premise of the “Gimun and Daesa dispute” in 513. Therefore, this article argues that it is necessary to be more cautious when restoring the historical fact of the time through the specification of related place names.

        Predictors of 3-month mortality with muscle ultrasound and palliative prognostic tools among patients admitted to palliative care units

        Zeynep Irmak Kaya,Yelda Öztürk,Sinem Gürcü,Gülgün Uncu,Anıl Uçan,Mert Eşme,Berrin Yalınbaş Kaya,Cafer Balci 대한내과학회 2023 The Korean Journal of Internal Medicine Vol.38 No.4

        Background/Aims: Prognostic factors are an important issue in progressive and life-limiting diseases. This study evaluate 3-month mortality in patients admitted to the palliative care unit (PCU). Methods: In this study, the patient’s demographics, comorbidities, nutritional status, and laboratory values were recorded. The palliative performance scale (PPS), the palliative prognostic index (PPI), and the palliative prognostic (PaP) score were calculated. The rectus femoris (RF) cross-sectional area (CSA), RF muscle thickness, gastrocnemius (GC) medialis muscle thickness, pennation angle and fascicle length of the GC were measured by ultrasound for survival prediction. Results: A total of 88 patients enrolled during the study period, with a mean age of 73.6 ± 13.3 years and a 3-month mortality rate of 59.1%. The findings of a multivariable Cox proportional hazards regression model based on age, gender, C-reactive protein level and Nutrition Risk Screening 2002 scores as covariates revealed the PPI and the PaP score to be significant predictors of 3-month mortality. In addition, in the unadjusted Cox proportional hazard regression analysis, the CSA of the RF muscle was also found to be a significant predictor of 3-month mortality. Conclusions: Findings revealed that the combined use of the CSA of the RF, the PPI, and the PaP score are reliable predictors of mortality in patients admitted to the PCU.

        Kaya, Emine,Gunec, Huseyin Gurkan,Aydin, Kader Cesur,Urkmez, Elif Seyda,Duranay, Recep,Ates, Hasan Fehmi Korean Academy of Oral and Maxillofacial Radiology 2022 Imaging Science in Dentistry Vol.52 No.-

        Purpose: The aim of this study was to assess the performance of a deep learning system for permanent tooth germ detection on pediatric panoramic radiographs. Materials and Methods: In total, 4518 anonymized panoramic radiographs of children between 5 and 13 years of age were collected. YOLOv4, a convolutional neural network (CNN)-based object detection model, was used to automatically detect permanent tooth germs. Panoramic images of children processed in LabelImg were trained and tested in the YOLOv4 algorithm. True-positive, false-positive, and false-negative rates were calculated. A confusion matrix was used to evaluate the performance of the model. Results: The YOLOv4 model, which detected permanent tooth germs on pediatric panoramic radiographs, provided an average precision value of 94.16% and an F1 value of 0.90, indicating a high level of significance. The average YOLOv4 inference time was 90 ms. Conclusion: The detection of permanent tooth germs on pediatric panoramic X-rays using a deep learning-based approach may facilitate the early diagnosis of tooth deficiency or supernumerary teeth and help dental practitioners find more accurate treatment options while saving time and effort

      • Effect of aggregate mineralogical properties on high strength concrete modulus of elasticity

        Kaya, Mustafa,Komur, M. Aydin,Gursel, Ercin Techno-Press 2022 Advances in concrete construction Vol.13 No.6

        Aggregates mineralogical, and petrographic properties directly affect the mechanical properties of the produced high strength. This study is focused on the effects of magmatic, sedimentary, and metamorphic aggregates on the performance of high strength concrete. In this study, the effect of the mineralogical properties of aggregates on the compressive strength and modulus of elasticity of high-strength concrete was estimated by Artifical Neural Network (ANN). To estimate the compressive strength and elasticity modules, 96 test specimens were produced. After 28 days under suitable conditions, tests were carried out to determine the compressive strength and modulus of elasticity of the test specimens. This study also focused on the application of artificial neural networks (ANN) to predict the 28-day compressive strength and the modulus of elasticity of high-strength concrete. An ANN model is developed, trained, and tested by using the available test data obtained from the experimental studies. The ANN model is found to predict the modulus of elasticity, and 28 days compressive strength of high strength concrete well, within the ranges of the input parameters. These comparisons show that ANNs have a strong potential to predict the compressive strength and modulus of elasticity of high-strength concrete over the range of input parameters considered.

        POSITION VECTOR OF A DEVELOPABLE q-SLANT RULED SURFACE

        Kaya, Onur,Onder, Mehmet The Kangwon-Kyungki Mathematical Society 2018 한국수학논문집 Vol.26 No.4

        In this paper, we study the position vector of a developable q-slant ruled surface in the Euclidean 3-space $E^3$ in means of the Frenet frame of a q-slant ruled surface. First, we determinate the natural representations for the striction curve and ruling of a q-slant ruled surface. Then we obtain general parameterization of a developable q-slant ruled surface with respect to the conical curvature of the surface. Finally, we introduce some examples for the obtained result.

        NEW EXTREMAL BINARY SELF-DUAL CODES OF LENGTHS 66 AND 68 FROM CODES OVER R<sub>k,m</sub>

        Kaya, Abidin,Tufekci, Nesibe Korean Mathematical Society 2017 대한수학회보 Vol.54 No.1

        In this work, four circulant and quadratic double circulant (QDC) constructions are applied to the family of the rings $R_{k,m}$. Self-dual binary codes are obtained as the Gray images of self-dual QDC codes over $R_{k,m}$. Extremal binary self-dual codes of length 64 are obtained as Gray images of ${\lambda}-four$ circulant codes over $R_{2,1}$ and $R_{2,2}$. Extremal binary self-dual codes of lengths 66 and 68 are constructed by applying extension theorems to the ${\mathbb{F}}_2$ and $R_{2,1}$ images of these codes. More precisely, 10 new codes of length 66 and 39 new codes of length 68 are discovered. The codes with these weight enumerators are constructed for the first time in literature. The results are tabulated.

        Kaya Ufuk,Dal Yılmaz Ümran 대한의학회 2022 Journal of Korean medical science Vol.37 No.35

        Background: In this context, discharge training and telephone counseling given to patients who underwent coronary artery bypass graft surgery increase the ability of patients to cope with and adapt to their self-care. Methods: This study was a randomized controlled, experimental design. Both experimental and control groups consisted of 35 individuals with G*power analysis (n = 70). Patients in the experimental group were given discharge training and telephone counseling for two months. At the end of the process, data collection forms were administered to both groups for the last time. Necessary ethical approvals were taken and consent was taken from the patients. Results: After the discharge training and telephone counseling given to the experimental group, the mean Exercise of Self-Care Agency Scale (ESCA) score of the patients increased by 13.94; the mean Coping and Adaptation Processing Scale (CAPS) increased by 13.6. The mean ESCA score of the control group increased by 7.86; the mean CAPS score increased by 9.14. The effect size that occurred for both groups was statistically significant (P < 0.05). Conclusion: Positive results were achieved in the experimental group which received given discharge training and telephone counseling.

      • Maturation effect on strength of high-strength concretes which produced with different origin aggregates

        Kaya, Mustafa,Komur, M. Aydin,Gursel, Ercin Techno-Press 2022 Advances in concrete construction Vol.14 No.2

        This paper presents an application of the maturation effect on the strength of high-strength concrete which is produced with different origin aggregates. While investigating the maturation effect on HSC 384 specimens were prepared with 22 different origin aggregates. These prepared specimens were subjected to the standard compressive tests which were applied after curing for 2, 7, 28, and 56 days under appropriate conditions. The test results revealed that bright surface-low adherence behavior is valid in normal strength concretes, but is not as effective as expected in high-strength concretes. The application of artificial neural networks (ANNs) to predict 2, 7, 28, and 56 day compressive strength of HSC is also investigated in this paper. An ANN model is built, trained, and tested using the available test data gathered from experimental studies. The ANN model is found to predict 2, 7, 28, and 56 days of compressive strength of high-strength concrete well within the ranges of the input parameters considered. These comparisons show that ANNs have strong potential as a feasible tool for predicting the compressive strength of high-strength concrete within the range of the input parameters considered.
