Objective: Cervical length (CL) is a potential screening tool to predict preterm delivery for high risk women. Also it can be used for prediction of spontaneous labor or successful induction of labor. The objection of this presentation was to assess association between CL and previous vaginal delivery. Methods: Prospective observational cohort study was conducted from Jul. 2015 to Dec. 2017 at tertiary hospital. We measured CL at 18- 22 weeks, 22-26 weeks, 30-32 weeks and 36-37 weeks for all pregnant women who visited our hospital for antenatal care. Pregnant women with multifetal pregnancy, cerclage during pregnancy, fetal death in uterus and preterm delivery were excluded. Student t test was conducted between history of previous delivery and cervical length at each gestational week. Results: We included 595 pregnant women and their records of CL. At 18-22 weeks of gestation, there was no significant association between previous vaginal delivery and CL. At 22-26 weeks of gestation, women with previous vaginal delivery (N = 356) had a shorter CL compared with women without previous vaginal delivery (N=239). (mean CL in women with previous vaginal delivery 34.8 ± 5.8 mm, women without previous vaginal delivery, 36.4 ± 6.3 mm, P = 0.033). At 30-32 and 36-37 weeks of gestation, women with previous vaginal delivery had shorter CL than women without history of vaginal delivery significantly (P= 0.038 and 0.002, respectively). Maternal height, body mass index, birthweight, and gestational week at delivery were not associated with history of vaginal delivery. Conclusion: CL at 22-26 weeks and at 30 -32 weeks and 36-37 weeks are significantly associated with previous vaginal delivery. When we measure and use CL as a predictor for preterm or term labor, history of vaginal delivery should considered.

Objective: To investigate the risk of uterine sarcoma during uterine surgery in university hospital in Korea. Methods: Design: Retrospective cohort study Setting: Multicencet academic university hospitals Patients or Participants: Patients undergoing myomectomies performed for presumed uterine leiomyomas by gynecologists between 2010 and 2017. Interventions: All patients undergone myomectomy for presumed leiomyoma. Results: Measurements and Main Results: Total 3107 cases of myomectomy were identified using clinical databases. There were 2118 (68.2%) cases of laparoscopic/robot-assisted myomectomy, 989 (31.8%) cases of open myomectomy. We identified 32 uterine malignancies. In 3 cases, there was no evidence of a malignancy preoperatively and hiostologic comfirmed to uterine sarcomas postoperatively( all 3 cases were underwent open myomectomy) . Conclusion: Conclusion: A small risk(0.09%[3/3107]) of uteine sarcoma during myomectomy withour power morcellation was found in our study. We did not observe on occult case of sarcoma after laparoscopi/robot-assisted myomectomy with power morcellation. For these reasons, minimally invasive surgery with morcellation is still considerable option for treatment of myomas.

『삼국유사』 「원성대왕」조의 원성왕 형상

박성혜 ( Park Seonghye ) 동방비교연구회 (구 한국동방문학비교연구회) 2017 동방문학비교연구 Vol.7 No.-

이 글은 『삼국유사』 「기이」편에 수록된 「원성대왕」조를 고찰한 것이다. 「원성대왕」조는 5개의 단위담으로 구성되어 있는데 기존의 논의는 여러 단위담중 일부에 초점을 맞춰 논의를 진행하였다. 이 글은 단위담 전반을 대상으로 논의를 확장하여, 「원성대왕」조라는 이름 아래 원성왕이 어떻게 형상화되었는지를 구체적으로 밝혔다. 주지하다시피 원성왕은 신라 하대의 성립에 중추적인 역할을 했던 인물이다. 「원성대왕」조를 구성하는 단위담은 각각 북천신, 만파식적, 호국룡, 여의주 등을 중심 소재로 삼아 원성왕의 왕으로서의 탁월함을 형상화하고 있다. 첫 번째 단위담은 신라의 모태가 되는 사로국 때부터 왕권의 정통성을 상징했던 북천신을 문화적 표상으로 끌어와서, 신라 왕조의 신, 즉 시조로부터 왕으로서의 지위를 인정받는 원성왕을 보여준다. 두 번째 단위담은 중대 왕권의 상징이자 신물인 만파식적을 원성왕의 아버지인 효양이 원성왕에게 건네주는 것으로 형상화되어 있다. 이는 상대의 시조에게 권위를 인정받을 뿐만 아니라 신라 중대의 계승자로 자리한 원성왕을 강조한다. 세 번째 단위담은 당나라 사신과 하서국 사람들이 조장한 위기를 극복하고, 호국용들을 구해오는 원성왕이 그려진다. 앞서 두 번째 단위담에서 일본의 침략을 막아낸 것과 더불어 당나라의 사신으로부터 탄복을 자아내는 원성왕의 형상은 복잡한 대외관계 속에서 신라를 지키는 왕의 형상이다. 특히 하서국 사람 2명이 호국용에게 주술을 걸어 잡아가는 형상은 원성왕이 즉위하던 당시 경쟁자였던 김주원이 하서량, 즉 명주로 물러나고 그의 아들과 손자가 각각 원성왕의 손자인 헌강왕 때에 반란을 일으켰던 역사적 사실을 형상화 한 것으로 이해할 수 있다. 네 번째 단위담은 자라에게 보시를 베풀었던 사미 묘정이 그 보답으로 자라에게 구슬을 받고, 이 구슬로 인해 여러 사람들에게 사랑을 받고 당나라 황제까지 만나게 되었는데, 그런데 이 구슬이 당황제가 잃어버렸던 여의주였다는 내용이다. 『장자』 외편에 실린 상망일화를 끌어와서 새롭게 구성된 이 단위담은 불교의 유사(遺事)를 기록하려 한 『삼국유사』의 편찬 의도와 관련하여 불교의 세상과 연결될 수 있는 원성왕의 모습을 형상화 한 것으로 볼 수 있다. 원성왕 증손자인 애장왕 때에 이르러 원성왕은 신라 왕실의 제사인 오묘(五廟)에서 ‘원성대왕’이라는 이름으로 봉안되었으며, 이후에도 꾸준히 신라 하대의 열조(烈祖)로서 인식되었다. 원성왕 사후에 지속되었던 의례와 당대에 향유되었던 다양한 설화 및 역사적 사실들은 원성왕을 둘러싸고 새로운 신화가 만들어지는 데 일조하였다. 여기에 승려 일연의 편찬의도까지 더해져 역사적 인물이자 동시에 설화적 인물로서의 원성왕이 구성될 수 있었던 것이다. This paper is a study on the article “Wonseogdaewang” in Chapter Kiyi(紀異), Samguk Yusa. Previous studies have focused only on parts of this article, especially the first and second substories. However, for proper understanding of this article, it is necessary to study whole article, which consists of five substories. This paper begins with the question of how this article was constructed and how the image of King Wonseong was formed under the name of ‘Wonseogdaewang’. As everyone knows, King Wonseong is a person who played a pivotal role in opening up ‘the later period of Silla’. The “Wonseogdaewang” article portrays the eminence of King Wonseong using the following cultural symbols: the god of the northern river(北川神), Manpasikjeok(萬波息笛), the kingdom defending dragon (護國龍) and Yeoiju. In the first substory, King Wonseong is depicted as a king who has been acknowledged by the progenitor of Silla through the cultural symbol of the god of the northern river, which has embodied royal authority since ‘the early period of Silla’ The second substory shows Hyoyang, the father of King Wonseong, delivering Manpasikjeok to King Wonseong. This scene portrays King Wonseong not only as a king authorized by the progenitor, but also as a successor to kingdom of ‘the middle period of Silla’. The third substory depicts King Wonseong overcoming the crisis caused by an envoy of Tang and the people of Haseoguk. This portrayal of King Wonseong as a figure who was admired by the envoy of Tang for his wisdom, along with the tale of King Wonseong blocking the Japanese invation of Silla in second substory, emphasizes King Wonseong’s ability to manage foreign relations. And the portrayal of the people of Haseoguk stealing dragons out of country by using magic is considered to be representation of the historically true event of Kim Joowon’s son and grandson rebelling against King Heongang(憲康王), the grandson of King Wonseong. The fourth substory is about a Buddhist acolyte. King Wonseong holds a Buddhist mass in the palace. During this mass, a Buddhist acolyte named Myojeong(妙正) gives alms to a soft-shelled turtle and the turtle gives him a marble. Myojeong is loved by everybody and even meets China’s emperor. But the marble turns out to actually be the emperor’s lost marble. This story, which was constructed by taking the anecdote of Sangmang(相忘) from the outer chapter of Zhuangzi(莊子) and modifying it, portrays King Wonseong as a figure connected to Buddhism. King Wonseong was recognized as a great ancestor even in ‘the later period of Silla’, and he was entitled Wonseongdaowang(The Great Wonseong) in a memorial service under the reign of King Aejang(哀莊王). Continued rituals, the various tales that circulated at that time and historical facts have contributed to the creation of the myth surrounding King Wonseong. The compilation intention of Iryeon(一然), has further cemented the image of King Wonseong both as a historical figure and a literary figure.

Seonghye Choi,Jang Hoon Lee,Moon Sung Park 대한신생아학회 2019 Neonatal medicine Vol.26 No.4

Disseminated neonatal herpes simplex virus (HSV) infection is a severe disease with a high mortality rate. Here, we report the patient presented with fulminant hepatic failure secondary to HSV infection followed by renal failure without any mucocutaneous symptoms. The patient recovered after treatment with acyclovir and peritoneal dialysis. This is the first known case of a patient in Korea who survived disseminated HSV infection with fulminant liver failure followed by renal failure without undergoing liver transplantation.

A Trace Mechanism of Change History in the Presence of Refactoring

Seonghye Yoon,Chaeyoung Lee,Sooyong Park,Mansoo Hwang 보안공학연구지원센터 2015 International Journal of Software Engineering and Vol.9 No.9

Nowadays, changes in software development are inevitable. Therefore, understanding and analysis of changes considered more important than anything else. The existing version control systems, which are used for effective change management, are impossible to trace changes in the presence of refactoring. There have been a number of approaches proposed for trace changes using operation-based mechanisms or rule-based mechanisms. However, it has many limitations with excessive recording or not sufficient coverage. In this approach, we define four rules based on M.Flower’s refactoring techniques and find an origin method matching the pattern of changed source code with the pre-defined rules. The case study shows that the proposed mechanism is effective Also, case study looking for open source project code changes about the origin method show the proposed mechanism’s effectiveness.

윤성혜 ( Seonghye Yoon ),박주연 ( Ju-yeon Park ) 한국교육공학회 2021 교육공학연구 Vol.37 No.2

최근 우리사회가 기업가적 경제로 전환됨에 따라 기업가정신의 중요성이 더욱 중요해지고 있으며, 이는 교육공학자에게도 필요한 역량이다. 이에 본 연구는 교육공학 전공생을 대상으로 기업가정신 교육을 실행하고 이의 효과성을 확인하고자 하였다. 이를 위하여 E 대학교에서 2019년 2학기 기업가정신 교육에 참여한 23명의 교육공학 전공생을 대상으로 양적, 질적 자료를 수집하였다. 수집된 자료 중 사전 및 사후 기업가정신 설문 응답 자료는 대응표본 t검정을 통해 기업가정신 교육의 효과성을 분석하였고, 개방형 설문 응답 자료와 에세이는 반복적 비교분석법을 통해 기업가정신 교육을 통해 배운 점과 교육공학자의 기업가정신 의미를 추출하였다. 연구 결과는 다음과 같다. 첫째, 교육공학 전공생은 기업가정신의 모든 하위 요소(성취욕구, 자기통제능력, 위험감수성, 창의력, 자기효능감)에서 통계적으로 유의한 향상을 보였다. 둘째, 교육공학 전공생은 기업가정신 교육을 통해 기업가정신의 필요성, 실패를 두려워하지 않고 도전하는 자세, 경영적 사고, 진로 성찰 등을 배운 것으로 나타났다. 셋째, 교육공학 전공자로서 기업가정신의 의미는 교육변화를 주도하는 적극성, 실천성, 교수설계자로서의 혁신성으로 인식하였다. 이를 통해 교육공학 전공생을 위한 기업가정신 교육의 효과를 실증적으로 확인하였으며, 이에 따른 시사점으로 교육공학자가 혁신적 교육을 창출, 관리, 활용하는 과정에서 적극성, 실천성, 혁신성을 기르는 기업가정신 교육이 필요함을 논의하였다. With society’s recent transition to an entrepreneurial economy, entrepreneurship education has gained significance, especially as a necessary competency for educational technologists. This study therefore aims to implement entrepreneurship education for educational technology students and to verify its effectiveness. Quantitative and qualitative data were collected from 23 educational technology students who participated in entrepreneurship education in the second semester of 2019 at E University. Preand post-entrepreneurship survey response data were analyzed to access the effectiveness of entrepreneurship education through a paired sample t-test. Open-ended survey response data and essays were also evaluated through constant comparative method to identify what students learned from entrepreneurship education and their perceptions on the significance of entrepreneurship. The results of the study are as follows. First, students showed statistically significant improvements in all sub-factors of entrepreneurship (need for achievement, locus of control, risk-taking, creativity, and self-efficacy). Second, they learned the necessity of entrepreneurship, possessing a challenge spirit unafraid of failure, management thinking, and reflecting on their career. Third, the key ideas of entrepreneurship among educational technologists were recognized as proactiveness leading to educational change, practicability, and innovativeness in instructional design. The effects of entrepreneurship education on educational technology students were thus verified empirically. The study addresses the need for entrepreneurship education that fosters proactiveness, practicality, and innovativeness in the process of creating, managing, and implementing innovative education for educational technologists.

기존 시스템을 프로덕트라인으로 재공학하기 위한 코드 변경 기반의 휘처 추출 기법

윤성혜(Seonghye Yoon),박수용(Sooyong Park),황만수(Mansoo Hwang) 한국컴퓨터정보학회 2016 韓國컴퓨터情報學會論文誌 Vol.21 No.5

Software maintenance becomes extremely difficult, especially caused by multiple versions in project-based or customer-oriented software development methodology. For reducing the maintenance cost, reengineering to software product line can be a solution to the software which either is a family of products nevertheless little different functionalities or are customized for each different customer’s requirement. At an initial stage of the reengineering, the most important activity in software product line is feature extraction with respect to commonality and variability from the existing system due to verifying functional coverage. Several researchers have studied to extract features. They considered only a single version in a single product. However, this is an obstacle to classify the commonality and variability of features. Therefore, we propose a method for systematically extracting features from source code and its change history considering several versions of the existing system. It enables us to represent functionalities reflecting developer’s intention, and to clarify the rationale of variation.

Objective-Extrapyramidal signs (EPS) are common in patients with mild cognitive impairment (MCI). However, few studies have assessed the effect of EPS on the clinical course of MCI. We aimed to evaluate whether patients with EPS show more frequent progression from MCI to Alzheimer’s disease (AD) and to other types of dementia. Methods-Participants (n=882) with MCI were recruited, and were followed for up to 5 years. The EPS positive group was defined by the presence of at least one EPS based on a focused neurologic examination at baseline. Results-A total of 234 converted to dementia during the follow-up period. The risk of progression to AD was lower in the patients with EPS after adjusting for potential confounders [hazard ratio (HR)=0.70, 95% confidence interval (CI)=0.53-0.93, p=0.01]. In contrast, the patients with EPS had a six-fold elevated risk of progression to dementia other than AD (HR=6.33, 95%CI=2.30–17.39, p<0.001). Conclusion-EPS in patients with MCI is a strong risk factor for progression of MCI to non-Alzheimer dementia. The careful neurologic examination for EPS in patients with MCI can yield important clinical information for prognosis.

Potential use of 3-(trimethoxysilyl)propyldimethyl octadecyl ammonium chloride as an antimicrobial and antiviral agent for the disinfection of personal protective equipment

김유진,Hana Youn,Junbeom Kim,Daye Lee,Seonghye Go,Ji-eun Park,Sunhak Lee,Jinyong Noh,남상섭 대한백신학회 2020 Clinical and Experimental Vaccine Research Vol.9 No.2

Currently, no vaccine or established therapeutic agents are available for coronavirus disease 2019. The sharp increase in demand for personal protective equipment (PPE) necessitates an improvement in the protective efficacy of PPE. We evaluated the potential antimicrobial and antiviral effects of a surface-coating disinfectant (3-(trimethoxysilyl)propyldimethyl octadecyl ammonium chloride, Si-QAC) when applied onto PPE. Si-QAC-pre-coated PPE was artificially contaminated with either influenza virus or Salmonella. The results showed significantly reduced influenza and Salmonella titers in Si-QAC-coated PPE; these antimicrobial effects lasted 7 days. This suggests that this surface-coating disinfectant effectively reduces pathogen contamination of PPE, enabling their safe and long-term use.
