This study collected and analyzed the original texts of the economic debate among the 20th presidential election candidates held in 2022 to analyze the words used by the candidates in TV debates using topic modeling techniques. For data analysis, frequency analysis was performed through a text preprocessing process, and for topic analysis, after using the word frequency-reverse document frequency (TF-IDF) technique, potential Direclet allocation (LDA) topic modeling was performed using R's ldatuning package. As a result of the study, the word extracted with the highest frequency was 'speech', followed by 'we', 'candidate', 'thought', 'economy', 'story', 'people', 'government', 'problem', and 'country'. There were seven topics in total, which were suggested as "the direction of the next government's economic policy", "diverse digital data economy and role", "various market economy issues", "the direction of the next government's economic growth", "various directions of the next government's economic support", "how to secure financial soundness", and "the necessity of the economic president". As a result, the candidates who participated in the discussion were found to have conducted the discussion within a set economic field, but some candidates were found to be out of the scope of the topic, such as bringing up the issues around the other candidate. This study is expected to be highly utilized as basic data in that it analyzed the contents of the TV debate by deriving the linguistic use of candidates participating in the TV debate through topic modeling techniques rather than traditional research methods.

This study analyzed the present condition of competitive debates sponsored by the National Election Broadcasting Debate Commission in order to find means for their improvement. This analysis focused particularly on questionnaires by university students who participated in debate championships in 2009 and 2010.  Based on the results, problems were examined and recommendations for improvement were made. Specific recommendations included selection of a fixed annual schedule, efforts to increase the number of participating students, implementation of a systematic operating system, and alteration of the debate format.  Ultimately, the goal is to increase the participation rate of university students and to promote debate culture in Korea. 본 연구는 토론대회의 개선방안을 모색하기 위하여 중앙선거방송토론위원회가 주최한 토론대회의 현황과 설문조사 결과를 분석하였다. 분석을 위해서는 국내 토론대회의 개최현황과 2009년과 2010년 중앙선거방송토론위원회가 주최한 토론대회에 참가한 대학생들의 설문조사를 활용하였다. 이것을 바탕으로 그동안 나타났던 문제점을 살펴보고 그에 따른 개선방안을 마련하였다. 토론대회의 개선방안으로는 대회 개최시기의 조정, 참가 대학생들의 확대, 대회의 체계적인 운영, 토론진행방식의 보완을 제시하였다. 결국 대학생들의 참여율을 높이고 우리나라 토론문화를 보다 더 활성화하기 위한 방안이다.

MDCT 검사에서 환자 체중을 이용한 선량 평가

권성욱,동경래,권대철,구은회,최지원,정운관,Kwon, Seong-Ohk,Dong, Kyung-Rae,Kweon, Dae-Cheol,Goo, Eun-Hoe,Choi, Ji-Won,Chung, Woon-Kwan 한국의학물리학회 2010 의학물리 Vol.21 No.3

환자가 두부, 흉부, 복부 MDCT 검사에서 피폭되는 선량을 평가하였다. 선량의 지표는 CTDIvol, DLP, 유효선량을 평가하여 환자의 체중과 선량과의 상관관계를 분석하였다. CT 검사에서 검사 조건을 동일하게 하여 연속적으로 두부(520명), 흉부(531명), 복부(724명) 환자를 대상으로 하였다. CTDIvol과 DLP 평균선량은 두부검사에서 CTDIvol (48.6 mGy), DLP (1,604 $mGy{\cdot}cm$), 흉부검사에서 CTDIvol (6.9 mGy), DLP (250 $mGy{\cdot}cm$), 복부는 CTDIvol (10.5 mGy), DLP (575 $mGy{\cdot}cm$), 유효선량은 두부, 흉부, 복부에서 3.6, 4.2, 8.6 mSv로 분석되었다. 환자의 체중과 선량과의 상관분석에서 두부, 흉부, 복부에서, 두부는 상관관계가가 보이지 않았고, 흉부는 CTDIvol ($r^2$=0.62), DLP ($r^2$=0.694), 복부는 CTDIvol ($r^2$=0.691), DLP ($r^2$=0.741)와 양의 상관관계를 나타내냈다. 검사에 따른 체중과의 상관관계를 이해하고 검사 하면 방사선 피폭에 의한 선량을 평가하고 관리하는데 기여 할 수 있을 것이다. The purpose of this study provides measurements of radiation dose from MDCT of head, chest, abdomen and pelvic examinations. A series of dose quantities that are measured of patient weight to compare the dose received during MDCT examinations. Data collected included: weight together with CT dose descriptors, volume CT dose index (CTDIvol) and dose length product (DLP). The effective dose was also estimated and served as collective dose estimation data. Data from 1,774 adult patients attending for a CT examination of the head (n=520) or chest (n=531) or abdomen (n=724) was obtained from spiral CT units using a same CT protocol. Mean values of CTDIvol was a range of 48.6 mGy for head and 6.9, 10.5 mGy for chest, abdomen examinations, respectively. And mean values of DLP was range of 1,604 $mGy{\cdot}cm$ for head, 250 $mGy{\cdot}cm$ for chest, 575 $mGy{\cdot}cm$ for abdomen examinations, respectively. Mean effective dose values for head, chest, abdominal CT were 3.6, 4.2, and 8.6 mSv, respectively. The degree of CTDIvol and DLP was a positive correlation with weight. And there was a positive correlation for weight versus CTDIvol ($r^2$=0.62), DLP ($r^2$=0.694) in chest. And head was also positive correlation with weight versus CTDIvol ($r^2$=0.691), DLP ($r^2$=0.741). We conclude that CTDIvol and DLP is an important determinant of weight within the CT examinations. The results for this study suggest that CT protocol should be tailored according to patient weight.

권성욱,민현식,윤대성,최원준,최인석,나유미,강포순,이상억 대한혈관외과학회 2011 Vascular Specialist International Vol.27 No.1

Extensive visceral vein thrombosis, including the femoral vein, iliac vein, superior mesenteric vein, splenic vein and portal vein, is an uncommon type of thrombosis that is associated with significant mortality and morbidity. Making an early diagnosis and adequate management are very important. We present here the case of a 39-year-old woman with extensive visceral vein thrombosis and complicated small bowel necrosis and perforation. She had no known prothrombotic conditions, but the laboratory findings showed an elevated level of factor VIII. The patient’s condition improved without complication after resection of the infarcted and perforated small bowel along with immediate postoperative anticoagulant therapy. On the follow up, the size of the thrombosis was decreased and there was no complication.

Purpose: To evaluate the effect of the mixed solution of hyaluronate and sodium carboxymethylcellulose (HACMC, Guardix-sol®) in reducing postoperative adhesion following strabismus surgery. Methods: In 16 rabbits out of 20 rabbits, 3 mm recession of the superior rectus muscle was performed on both eyes and HACMC solution was applied only to one eye which was randomly chosen. The rabbits were divided into a surgery-HACMC group and a surgery-no HACMC group. As a control group, the remaining 4 rabbits had no procedures performed. After 3 weeks, both eyes of 8 rabbits with surgery and 2 rabbits of the control group were enucleated. After staining with hematoxylin-eosin and Masson\'s trichrome, a histologic examination was performed. In the remaining 10 rabbits, the severity of adhesion in muscle and adjacent tissues was observed by blunt dissection. A researcher blind to the experiments performed all the examinations. Results: A significant reduction in the degree of adhesion (P=0.005) as well as decreased fibrosis (P=0.015) was observed in the surgery-HACMC group. Conclusions: The mixed solution of HACMC was effective in reducing postoperative adhesion after strabismus surgery in rabbits.

The Role of Large Animal Studies in Cardiac Regenerative Therapy Concise Review of Translational Stem Cell Research

권성욱,Alan C Yeung,Fumiaki Ikeno 대한심장학회 2013 Korean Circulation Journal Vol.43 No.8

Animal models have long been developed for cardiovascular research. These animal models have been helpful in understanding disease,discovering potential therapeutics, and predicting efficacy. Despite many efforts, however, translational study has been underestimated. Recently, investigations have identified stem cell treatment as a potentially promising cell therapy for regenerative medicine, largely be -cause of the stem cell’s ability to differentiate into many functional cell types. Stem cells promise a new era of cell-based therapy for salvag-ing the heart. However, stem cells have the potential risk of tumor formation. These properties of stem cells are considered a major concern over the efficacy of cell therapy. The translational/preclinical study of stem cells is essential but only at the beginning stages. What types of heart disease are indicated for stem cell therapy, what type of stem cell, what type of animal model, how do we deliver stem cells, and how do we improve heart function? These may be the key issues that the settlement of which would facilitate the transition of stem cell research from bench to bedside. In this review article, we discuss state-of-the-art technology in stem cell therapies for cardiovascular diseases.
