『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.

Effect of slag on stabilization of sewage sludge and organic soil

Kaya, Zulkuf Techno-Press 2016 Geomechanics & engineering Vol.10 No.5

Soil stabilization is one of the useful method of ground improvement for soil with low bearing capacity and high settlement and unrequired swelling potential. Generally, the stabilization is carried out by adding some solid materials. The main objective of this research was to investigate the feasibility of stabilization of organic soils and sewage sludge to obtain low cost alternative embankment material by the addition of two different slags. Slags were used as a replacement for weak soil at ratios of 0%, 25%, 50%, 75% and 100%, where sewage sludge and organic soil were blended with slags separately. The maximum dry unit weights and the optimum water contents for all soil mixtures were determined. In order to investigate the influence of the slags on the strength of sewage sludge and organic soil, and to obtain the optimal mix design; compaction tests, the California bearing ratio (CBR) test, unconfined compressive strength (UCS) test, hydraulic conductivity test (HCT) and pH tests were carried out on slag-soil specimens. Unconfined compressive tests were performed on non-cured samples and those cured at 7 days. The test results obtained from untreated specimens were compared to tests results obtained from soil samples treated with slag. Laboratory tests results indicated that blending slags with organic soil or sewage sludge improved the engineering properties of organic or sewage sludge. Therefore, it is concluded that slag can be potentially used as a stabilizer to improve the properties of organic soils and sewage sludge.

Kaya, Huseyin,Gokce, Ismail Kursad,Gungor, Sukru,Turgut, Hatice,Ozdemir, Ramazan The Korean Society of Pediatric Gastroenterology 2018 Pediatric gastroenterology, hepatology & nutrition Vol.21 No.4

Gastric hemangiomas are rare benign vascular tumors that can cause severe gastrointestinal system bleeding. We presented the case of a neonate with fresh bleeding and melena from the orogastric tube and detected gastric hemangioma in esophagogastroduodenoscopic examination. Propranolol is widely used in treatment of cutaneous hemangiomas and non-gastric gastrointestinal system hemangiomas. However, the surgical approach is preferred for treating gastric hemangiomas, and there are few reports of gastric hemangiomas associated with non-surgical treatment. Gastric hemorrhage decreased with antacid and somatostatin treatment. Propranolol treatment was initiated before the surgery decision. After three weeks of treatment, we observed regression in the hemangioma with endoscopic evaluation. During the course of treatment, the patient's gastrointestinal system bleeding did not recur, and there were no side effects associated with propranolol.

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 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.

Kaya Karabulut,Rıza Atav 한국섬유공학회 2020 Fibers and polymers Vol.21 No.8

Natural dyes are gaining importance in textile dyeing applications in recent years due to the fact many syntheticdyes are carcinogenic, mutagenic, and allergic. In this study, cotton knitted fabrics were dyed with extract solutions of 40different dye plants without the mordant usage. Afterwards color efficiency and fastness values of dyed samples wereevaluated. Dye plants that are able to give good color efficiency with sufficient fastness values were determined. Accordingto the experimental results it can be said that for yellow color pomegranate peel and turmeric; for red color madder andquince; for blue color indigo; for green color myrobalan; for brown color white onion peel and catechu give the optimumresults. Furthermore, it was tested whether ultraviolet protection effect could be obtained via dyeing with white onion peel orturmeric and it was found that both of these plants gave very good UV protection functionalization to cotton fabrics.

NEW EXTREMAL BINARY SELF-DUAL CODES OF LENGTHS 66 AND 68 FROM CODES OVER R_k,m

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.
