『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.

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, Filiz Acun,Hamamcl, Nihal,Uysal, Ersin,Yokus, Beran The Korean Association Of Orthodontists 2011 대한치과교정학회지 Vol.41 No.1

Objective: The aim of this study was to measure tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) levels around miniscrews used for anchorage during a 3-month period of canine distalization. Methods: Sixteen patients (8 boys, 8 girls; mean age, $16.6{\pm}2.4$ years) whose upper first premolars were extracted for orthodontic treatment were included in this study. Miniscrews were used as an anchorage unit in canine distalization. Thirty-two (32) miniscrew implants were placed bilaterally in the alveolar bone between the maxillary second premolars and first molars. The treatment, miniscrew, and control groups comprised upper canines, miniscrew implants, and upper first premolars, respectively. Peri-miniscrew implant crevicular fluid and gingival crevicular fluid were obtained before applying force and at 1, 24, and 48 hours, and at 7 and 21 days, and 3 months after applying force. Results: During the 3-month period, the (TNF-${\alpha}$) levels increased significantly at 24 hours only in the treatment group (p < 0.01). In the miniscrew and control groups, there were no statistically Significant changes. No significant differences were observed between groups. Conclusions: Miniscrews can be conveniently used for anchorage in orthodontics.

Kaya Emine,Gunec Huseyin Gurkan,Aydin Kader Cesur,Urkmez Elif Seyda,Duranay Recep,Ates Hasan Fehmi 대한영상치의학회 2022 Imaging Science in Dentistry Vol.52 No.3

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.

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.

The Effects of Raw and Physical Processed Common Vetch Seed (Vicia sativa) on Laying Performance, Egg Quality, Metabolic Parameters and Liver Histopatology of Laying Hens

Kaya, Hatice,Celebi, S.,Macit, M.,Geyikoglu, F. Asian Australasian Association of Animal Productio 2011 Animal Bioscience Vol.24 No.10

This experiment was designed to evaluate the effects of the processing method of common vetch seed (CVS) (Vicia sativa) on laying performance, egg quality, metabolic parameters and liver histopatology during the peak production period in hens. Lohman layers, 46 wk of age in 6 replicate cages each containing 4 hens, were allocated randomly to one of four dietary treatments. Diets were control (C) diet containing no common vetch and experimental diets containing 25% raw common vetch (RCV), 25% soaked in water for 72 h with exchange of water every 24 h (SCV) and 25% soaked&boiled at $100^{\circ}C$ for 30 minute common vetch (SBCV). Inclusion of RCV into the diet deteriorated all laying performance variables. SCV did not alleviate the adverse effect of raw common vetch on feed intake, egg weight, feed conversion, final weight and weight change. SCV partially alleviated egg production (p<0.001). SBCV diminished the adverse effect on feed intake, egg weight, feed conversion, final weight and weight change compared to raw vicia sativa (p<0.001). No significant difference was detected between SBCV and the control group in terms of egg production, feed conversion, final weight and weight change. Regardless of the processing method, all the common vetch groups had lower shell strength compared to the control group. Haugh units did differ between all groups (p<0.001). Inclusion of RCV and SCV into the basal diet decreased triglyceride, cholesterol, total protein and serum glucose concentrations (p<0.001). Hovewer, inclusion of SBCV into the basal diet increased these parameters. Liver samples were stained with Hematoxylin and eosin (HE) and evaluated by light microscopy. A biopsy of native liver tissue was used as a control. No histopathologic finding was present in the control group. Raw V. sativa compared with the control caused lipid accumulations in hepatocytes, severe congestion of hepatic blood vessels, inflammation, increased numbers of Kupffer cells and sinusoidal dilatations. Whereas, the livers from groups given treated V. sativa showed only different degrees of sinusoidal dilatations. Findings from the present study point out the risk of increased hepatic damage due to use of raw Vicia sativa. Increasing treatment of V. sativa lead to a decrease of liver damages. Inclusion of raw and soaked vetch seeds in rations affected adversely all parameters examined in laying hens. But alleviation was observed when soaked and boiled vetch seeds (SBCV) were fed. The results of these experiments indicated that soaked&boiled Vicia sativa seeds may safely be used at a 25% level in rations of laying hens.

Kaya, Vildan,Yildirim, Mustafa,Demirpence, Ozlem,Yildiz, Mustafa,Yalcin, Aysen Yesim Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.9

Background: In our study, the LDH, albumin, hemoglobin, neutrophile, thrombocyte, lymphocyte counts and prognostic significance of neutrophile-lymphocyte and thrombocyte-lymphocyte ratios in NSCLC derived from these counts obtained during regular examinations of patients were examined. Materials and Methods: Histopathologically diagnosed non-small-cell-lung cancer patients between 2008 and 2010 were included in the study. Before the treatment, full blood count including routine lymphocyte count, blood biochemistry examinations including liver (AST, ALT, total protein, Albumin), LDH and kidney (BUN, Cre) function tests were performed. Results: A total of 156 patients, 76 of whom (48.7%) were female and 80 of whom (51.3%) were male were included. Mean hemoglobin level was determined as 12. Overall survival was found to be significantly dependent on whether patients were anemic or not (p: 0.005). Mean LDH level was determined as 233.4. There was nosurvival difference between patients with and without high LDH (p: 0.532). In patients where NLR showed systemic inflammatory response, overall survival was 10.8 months whereas this duration was 19.6 months in patients where the systemic inflammatory response was negative (p: 0.012). In patients where TLR showed systemic inflammatory response, overall survival was 13.6 months whereas this duration was 21.9 months in patients where the systemic inflammatory response was negative (p: 0.04). Conclusions: Molecular methods have been changing rapidly in today's world and they manage the treatment besides defining the prognosis of patients. However, easily accessible and cheap laboratory parameters should be considered in the prognosis of patients besides these new methods.

A Note on Relay Feedback Identification Under Static Load Disturbances

Kaya, Ibrahim The Korean Institute of Electrical Engineers 2015 Journal of Electrical Engineering & Technology Vol.10 No.1

Obtaining the parameters for PID controllers based on limit cycle information for the process in a relay controlled feedback loop has become an accepted practical procedure. If the form of the plant transfer function is known, exact expressions for the limit cycle frequency and amplitude can be derived so that their measurements, assumed error free, can be used to calculate the true parameter value. In the literature, parameter estimation for an assumed form of the plant transfer function has generally been considered for disturbance free cases, except a recently published work of the author. In this paper additional simulation results are reported on exact parameter estimation from relay autotuning under static load disturbances.

The role of vitamin D deficiency on COVID-19: a systematic review and meta-analysis of observational studies

Kaya Mehmet Onur,Pamukçu Esra,Yakar Burkay 한국역학회 2021 Epidemiology and Health Vol.43 No.-

OBJECTIVES: Although vaccination has started, coronavirus disease 2019 (COVID-19) poses a continuing threat to public health. Therefore, in addition to vaccination, the use of supplements to support the immune system may be important. The purpose of this study was to synthesize evidence on the possible effect of low serum vitamin D levels (25[OH]D< 20 ng/mL or 50 nmol/L) on COVID-19 infection and outcomes. METHODS: We searched Google Scholar, PubMed, Scopus, Web of Science, and ScienceDirect without any language restrictions for articles published between January 1 and December 15, 2020. We performed 3 meta-analyses (called vitamin D and COVID-19 infection meta-analysis [D-CIMA], vitamin D and COVID-19 severity meta-analysis [D-CSMA], and vitamin D and COV ID-19 mortality meta-analysis [D-CMMA] for COVID-19 infection, severity, and mortality, respectively) to combine odds ratio values according to laboratory measurement units for vitamin D and the measured serum 25(OH)D level. RESULTS: Twenty-one eligible studies were found to be relevant to the relationship between vitamin D and COVID-19 infection/outcomes (n= 205,869). The D-CIMA meta-analysis showed that individuals with low serum vitamin D levels were 1.64 times (95% confidence interval [CI], 1.32 to 2.04; p< 0.001) more likely to contract COVID-19. The D-CSMA meta-analysis showed that people with serum 25(OH)D levels below 20 ng/mL or 50 nmol/L were 2.42 times (95% CI, 1.13 to 5.18; p= 0.022) more likely to have severe COVID-19. The D-CMMA meta-analysis showed that low vitamin D levels had no effect on COVID-19 mortality (OR, 1.64; 95% CI, 0.53 to 5.06, p= 0.390). CONCLUSIONS: According to our results, vitamin D deficiency may increase the risk of COVID-19 infection and the likelihood of severe disease. Therefore, we recommend vitamin D supplementation to prevent COVID-19 and its negative outcomes.
