Purpose: Recent studies have reported that loss of bone mass is associated with renal function decline and increased fracture risks in chronic kidney disease (CKD) patients. The aim of this study was to investigate the best estimated glomerular filtration rate (eGFR) equation to detect osteopenia in CKD patients. Materials and Methods: This was a cross-sectional study, and 780 patients aged 50 years or above were classified into normal bone mass or osteopenia groups according to the -1.0 of T-scores at total hip and femur neck. Comparisons of area under the receiveroperating characteristic (ROC) curves (AUC) were performed to investigate significant differences among three eGFR formulas:Modification of Diet in Renal Disease, CKD-Epidemiology Collaboration (EPI) creatinine, and CKD-EPI cystatin C (CKD-EPI-Cys). Results: The mean age was 61 years old and the proportion of females was 37.3%. The total hip osteopenia group showed lower CKD-EPI-Cys eGFR levels (osteopenia group, 33.3±19.0 mL/min/1.73 m2; normal group, 48.1±26.2 mL/min/1.73 m2, p<0.001). In multiple logistic regression analysis, CKD-EPI-Cys eGFR was independently associated with osteopenia at the total hip (per 1 mL/min/1.73 m2 increase, odds ratio 0.98, 95% confidence interval 0.97–0.99, p=0.004) after adjusting for confounding variables. ROC curve analyses indicated that CKD-EPI-Cys shows the largest AUC for osteopenia at the total hip (AUC=0.678, all p<0.01) and the femur neck (AUC=0.665, all p<0.05). Conclusion: Decreased renal function assessed by CKD-EPI-Cys equation correlates with osteopenia better than creatinine-based methods in CKD patients, and the CKD-EPI-Cys formula might be a useful tool to assess skeletal-related event risks.

여대생의 자궁경부암, 인유두종 바이러스 감염 지식 및 예방행위 의도의 관계

권영은,이영은 사단법인 인문사회과학기술융합학회 2019 예술인문사회융합멀티미디어논문지 Vol.9 No.2

최근 국내 자궁경부암은 점차 감소하는 추세이긴 하나, 10-34세 연령 군에서 암발생률 3위를 차지하고 있어 여성 생식기 건강의 위험요소가 되고 있다. 특히 자궁경부암의 주요 원인으로 알려진 인유두종 바이러스 감염은 10대와 20대에서 가장 높은 유병률을 보이고 있다. 따라서 본 연구의 목적은 여대생의 자궁경부암 및 인유두종 바이러스 감염에 대한 지식을 알아보고 예방행위 의도와의 관계를 파악하여 여대생을 위한 보건 교육 중재프로그램의 기초자료를 제공하는데 있다. 연구대상은 B광역시 소재한 3곳의 대학교 재학 중인 여학생 192명이었고, 자료수집 기간은 2013년 10월 22일부터 동년 11월 25일이었다. 수집된 자료는 IBM SPSS 21.0을 활용하여 실수와 백분율, 평균, 표준편차, 평균평점, t-test, ANOVA 및 Scheffe's test로 분석하였다. 연구결과 여대생들의 자궁경부암 지식의 정답률은 46.8%로 낮게 나타났고, 인유두종 바이러스 감염 지식의 정답률은 31.1%로 매우 낮은 것으로 나타났다. 자궁경부암과 인유두종 바이러스 감염에 대한 예방행위 의도는 77.5%로 높게 나타났다. 여대생의 자궁경부암 지식이 높을수록 인유두종 바이러스 감염 지식이 유의하게 높은 것으로 나타났다. 따라서 본 연구 결과를 바탕으로 여자대학생 대상의 자궁경부암의 주요 원인인 인유두종 바이러스 감염에 대한 지식을 증진시킬 수 있는 보건교육 프로그램의 개발이 필요하다. 또한 예방행위 중 의도가 낮았던 자궁경부암 검사에 대한 의도를 증진시킬 수 있는 방안이 필요하다고 본다. Although the incidence rate of cervical cancer has recently tended to be gradually decreased in Korea, the rate in those aged 10-34 ranks No. 3, so cervical cancer becomes a risk factor of females' genital health. In particular, the HPV infection which has been known as a main cause for cervical cancer has the highest prevalence among those in their 10s and 20s. This study, therefore, aims to provide basic data of health education intervention programs for female college students, by examining their knowledge of cervical cancer and HPV infection and the relationship between it and their intention for preventive behavior. The subjects include 192 female students in three colleges located in B metropolitan, and data were collected from October, 22 to November, 25, 2013. The collected data were analyzed with the real number and percentage, average, standard deviation, average ratings, t-test, ANOVA and Scheffe's test, by using IBM SPSS 21.0. The findings show: the rate of correct responses to items regarding female college students' knowledge of cervical cancer was low(46.8%); the rate of correct responses to items regarding their knowledge of HPV infection was very low (31.1%); and preventive behavior intention for cervical cancer and HPV infection was high (77.5%). Although there was a significant correlation between their knowledge of cervical cancer and HPV infection, knowledge of both them had no significant relationship with preventive behavior intention. On the basis of the findings, the development of health education programs is required for enhancing knowledge of HPV infection, a main cause of cervical cancer. In addition, it will be necessary to consider medical check-ups for increasing the screening rate of cervical cancer for which female college students had weak preventive behavior intention.

구어체 종결어미 ‘-을걸’의 양태 의미 연구

권영은 한국어의미학회 2020 한국어 의미학 Vol.67 No.-

The purpose of this study is to clarify the colloquial sentence final ending ‘-ulkel’ has polysemy between Epistemic-Event modality and to discuss the meaning and syntactic characteristics of ‘-ulkel’. When a sentence can be interpreted with more than two meanings, it has polysemy. ‘-ulkel’ can express the two meanings: Speculation and Regret. While there is less argument that ‘-ulkel’ belongs to Epistemic modality when it has the meaning of Speculation, it is controversial what modal category ‘-ulkel’ belongs to when it has the meaning of Regret. This study critically reviewed preceding literatures on the modality and analyzed syntactic and modal meanings of ‘-ulkel’. Through this process, it is revealed that the Regret meaning of ‘-ulkel’ is affiliated with Event modality when the subject(usually speaker) was able to control the state of affairs in the past. A speaker expresses Willingness to control the state of affairs in the past when ‘-ulkel’ is used as Event modality. However, it is impossible for the present speaker to control the state of affairs in the past. This is the reason why the speaker regrets. Also, the meaning of Regret may arise as a result of unreal conditions and speculation and, in this process, ‘-ulkel’ has Epistemic modality. When ‘-ulkel’ is used as Epistemic modality, it represents probability and has a meaning of speculation based on integrated knowledge. The results of this study can be used to establish the meaning of ‘-ulkel’ of Regret which has not been unified until now, and to prove the relation between Epistemic-Event modality.

The aim of this paper is to shed light on the meaning, function, and grammatical characteristics of ‘-ulkel’. This paper investigates the relationship between the meanings of ‘speculation’ and ‘regret’ of ‘-ulkel’. ‘-ulkel’ shows polysemy through event and epistemic modality. ‘-ulkel’ as event modality is used to express a speaker’s ‘willingness’ to realize the state of affairs; however, when it comes to past events, the speaker’s ‘willingness’ becomes ‘wish’, therefore its function becomes ‘regret’. This ‘regret’ usually arises when the speaker was able to choose the state of affairs in the past. ‘-ulkel’ of epistemic modality is used to show the probability of the speaker’s judgment about factual status. With counterfactual conditions, ‘-ulkel’ can express ‘regret’ too. This paper discusses the choice of ‘-ulkel’ usage in counterfactual conditionals. ‘-ulkel’ can be expressed as event modality if the situation is controllable for the speaker, if not, it is expressed as epistemic modality. This paper also discusses the role of postposition ‘ul’(selectional listing) and the development of the meaning of ‘-ulkel’.

Kwon, Young-Eun. 2009. A Study on the Education of Korean Adverb tel(덜) ‘less’ Based on Corpus Analysis. The Language and Culture 5-2: 17-47. The purposes of this study are to clarify features of Korean adverb tel ‘less’ and to apply the result to Korean education as a foreign language. Korean learner’s corpus and Native speakers of Korean’s corpus were used to examine the frequencies of tel ‘less’ and the co-occurrence relation between adverb tel ‘less’ and predicates. The Korean adverb tel ‘less’ is usually studied at the lower level in Korean language learning; however, Korean learners have difficulty in using it because of its properties. The frequency of using tel ‘less’ in learner’s corpus was mush fewer than the frequency of using tel ‘less’ in corpus of native Korean speaker, and there were even many errors. In the corpus from native speakers of Korean, adverb tel ‘less’ was always used in comparative sentences, but the usage of tel ‘less’ was changed by characteristic of predicates in comparative sentences. If the adverb tel ‘less’ can be used with poda(보다) ‘than’, tel ‘less’ was used to compare degree of the predicate, which a subject of the sentence had, with another or other things had. However, if the adverb tel ‘less’ cannot be used with poda ‘than’, it was used to compare the degree of predicate itself. Thus, the adverb tel ‘less’ cannot be used when it cannot compare the degree of predicate. I extracted predicates which are frequently used with the adverb tel ‘less’ and presented a way of teaching the adverb tel ‘less’. It would be helpful to apply the properties of adverb tel ‘less’ and the teaching method of it to Korean learners. (Hankuk University of Foreign Studies)

Radiographic study of dermal fillers in the facial area: A series of 3 cases

권영은,안창현,최갑식,이두형,안서영 대한영상치의학회 2018 Imaging Science in Dentistry Vol.48 No.3

In recent years, as interest in maintaining beauty and a youthful appearance has grown, filler procedures such as soft tissue augmentation have become more popular. These fillers are sometimes seen as radiopaque shadows on radiographic images, either due to the fillers themselves or because of secondary reactions; such findings may present a diagnostic challenge to dentists. The present report describes 3 cases of dermal fillers observed in panoramic and cone-beam computed tomographic (CBCT) images. All 3 elderly female patients had filler injected into their cheeks and chin area for cosmetic purposes decades ago. On panoramic images, multiple symmetric radiopacities were observed in the facial area; on CBCT, these calcifications were seen in the subcutaneous tissue in various shapes and with varying density. In conclusion, dentists should be aware of the imaging characteristics of dermal filler, and should be able to differentiate dermal filler from other pathological findings.
