송미화,이영호,강운구 대한의료정보학회 2013 Healthcare Informatics Research Vol.19 No.1

Objectives: Clinical Practice Guidelines (CPGs) are an effective tool for minimizing the gap between a physician’s clinical decision and medical evidence and for modeling the systematic and standardized pathway used to provide better medical treatment to patients. Methods: In this study, sentences within the clinical guidelines are categorized according to a classification system. We used three clinical guidelines that incorporated knowledge from medical experts in the field of family medicine. These were the seventh report of the Joint National Committee (JNC7) on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure from the National Heart, Lung, and Blood Institute; the third report of the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults from the same institution; and the Standards of Medical Care in Diabetes 2010 report from the American Diabetes Association. Three annotators each tagged 346 sentences hand-chosen from these three clinical guidelines. The three annotators then carried out cross-validations of the tagged corpus. We also used various machine learning-based classifiers for sentence classification. Results: We conducted experiments using real-valued features and token units, as well as a Boolean feature. The results showed that the combination of maximum entropy-based learning and information gain-based feature extraction gave the best classification performance (over 98% f-measure) in four sentence categories. Conclusions: This result confirmed the contribution of the feature reduction algorithm and optimal technique for very sparse feature spaces, such as the sentence classification problem in the clinical guideline document.

Clinical professionals gain new information to assist in patient care when they read the medical literature. Similarly, in clinical preventive medicine, medical science documents that have previously published can be searched and evaluated in order to confirm the scientific support for the clinical preventive medical service offered in order to prevent chronic disease. This paper introduces the medical informatics techniques for knowledge extraction that can become the basis for clinical practice. Particularly, it discusses the clinical document retrieval and knowledge discovery tools that can search for extracting the knowledge which the medical expert desires with data mining techniques. For example, Clinical medical personnel and medical researchers can locate the information from the latest literature rapidly or find and evaluate the scientific basis for the treatment and prevention of infection. This study can be used when they analyze the correlation between accumulated and different type of data and contributes to the detection of new knowledge. Recently, the concern about the visualization of massive data and information is high as the importance of big data has received greater attention. Contributions to this technique and decision support tools will increase gradually due to the way support for decision-making through scientific evidence for the pattern changing disease is evaluated or as one of the clinical practice guidelines is accepted.

A Multi-Classifier Based Guideline Sentence Classification System

송미화,김성현,박동균,이영호 대한의료정보학회 2011 Healthcare Informatics Research Vol.17 No.4

Objectives: An efficient clinical process guideline (CPG) modeling service was designed that uses an enhanced intelligent search protocol. The need for a search system arises from the requirement for CPG models to be able to adapt to dynamic patient contexts, allowing them to be updated based on new evidence that arises from medical guidelines and papers. Methods:A sentence category classifier combined with the AdaBoost.M1 algorithm was used to evaluate the contribution of the CPG to the quality of the search mechanism. Three annotators each tagged 340 sentences hand-chosen from the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC7) clinical guideline. The three annotators then carried out cross-validations of the tagged corpus. A transformation function is also used that extracts a predefined set of structural feature vectors determined by analyzing the sentential instance in terms of the underlying syntactic structures and phrase-level co-occurrences that lie beneath the surface of the lexical generation event. Results: The additional sub-filtering using a combination of multi-classifiers was found to be more effective than a single conventional Term Frequency-Inverse Document Frequency (TF-IDF)-based search system in pinpointing the page containing or adjacent to the guideline information. Conclusions: We found that transformation has the advantage of exploiting the structural and underlying features which go unseen by the bag-of-words (BOW) model. We also realized that integrating a sentential classifier with a TF-IDF-based search engine enhances the search process by maximizing the probability of the automatically presented relevant information required in the context generated by the guideline authoring environment.

In Korea, drones, which are at the core of the 4th industrial revolution, are used to promote Korean New Deal policies to digitalize the SOC. Overseas, the use of convergence sensors, such as thermal imaging cameras, on drones is increasing in various industrial fields. In this research, to improve pavement quality in highway bridge pavement construction, a thermal imaging camera was mounted on a drone to measure and verify the temperature of the pavement work section. Using a laser thermometer allows the partial measurement of pavement temperature. It was confirmed that the proposed method allows not only real-time temperature monitoring of the whole pavement work section but also uniformity verification by checking temperature distribution. The proposed method has the potential to control highway pavement quality and enable quick decision-making on traffic opening times by reducing the possibility of misjudging road opening times(pavement surface temperature ≦ 40℃). 국내에서는 4차 산업혁명의 핵심기술인 드론 등을 이용하여 사회기반시설(SOC)를 디지털화하는 한국판뉴딜 정책을 추진 중에 있고, 국외에서도 열화상카메라 등 융복합센서를 드론에 탑재하여 다양한 산업 분야에서 활용하는 사례가 증가하고 있다. 본 연구에서는 고속도로 교면포장 공사에서 포장 품질을 개선하기 위하여 드론에 열화상카메라를 탑재하여 포장 작업 구간에 대한 온도 측정 및 검증을 수행하였다. 기존의 방식인 레이저 온도계를 활용한다면 포장 온도를 부분적으로만 측정이 가능하지만, 제안된 방식을 활용하면 포장 작업 구간 전체에 대한 실시간 온도 모니터링 뿐 아니라 온도 분포 확인을 통한 균일성 검증이 가능한 것을 확인하였다. 제안된 방식을 현장에 적용한다면 도로 개방 시기(포장 표면온도≦40℃)에 대한 오판의 가능성을 낮춰줌에 따라 고속도로 포장 품질관리 제고 및 신속한 교통 개방 시기 결정이 가능할 것으로 기대된다.

하계마을 이만규가의 ‘혼례홀기’ 연구

송미화 영남대학교 민족문화연구소 2023 민족문화논총 Vol.84 No.-

이 연구는 유천(柳川) 이만규가(李晩煃家)의 ‘혼례홀기(婚禮笏記)’가 하계마을에서 어떻게 시행되고 계승되었는지 살펴보는데 그 목적이 있다. 먼저 하계마을에서 혼례를 올리기 전 ‘혼례를 전제로 하는 관례’의 시행을 살펴보고, 이만규가에 전해진 ‘혼례홀기’가 하계마을에서 어떻게 계승되고 시행되었는지향산집과 향산일기, 유천집, 유천가에 전해지는 문서, 구술 자료를 중심으로 살펴보았다. 하계마을은 이황의 후손이 400여년을 살아오면서 이황의 학문을 가장 전형적으로 계승 발전시켜 나간 곳이다. ‘혼례홀기’에는 신랑과 신부의 서는 위치를 ‘서서위동향립(壻西位東向立), 부동위서향립(婦東位西向立)’이라고 기록하였다. 이것은 신랑이 서쪽에 서고, 신부가 동쪽에 서는 ‘서서부동(壻西婦東)’ 을 말한다. 성리대전 「가례」에 기록된 혼례의 동뢰연에서 신랑과 신부의 위치인 ‘서동부서(壻東婦西)’와 다르다는 것을 확인할 수 있다. 이황이 활동한 시기인 16세기 후반에서 17세기 전반은 성리학적 사회관습이 수용되면서 사회 구조가 변화하는 시기이다. 특히 이 시기에는 주희의 가례에 입각한 각종 예제가 사족들을 중심으로 빠르게 정착된 시기였다. 이황은 아들 이준에게 손자 안도가 관례를 올렸다는 것을 서신으로 알렸다. 이 시기에 유자(儒者)들은 주자의 가례에서 표명한 바와 같이 15~20세에 관례를올린 다음 스승의 문하로 나아가 1년 이상, 혹은 평균 3년 이상 학문을 연마한다음 혼례를 거행한 경우가 많았다. 18세기 중반부터 20세기 초반에 시행된 관례는 독립된 의례가 아닌 혼례의준비 과정으로 축소되는 경향이 나타나고 있다. 이것은 ‘입지를 위한 관례’로서의 독자적 위상을 지니고 있었던 관례의 의미가 약화되었다고 볼 수 있다. 기록과 문서, 그리고 문집과 구술 자료를 통해 1810년경부터 1960년대까지 하계마을에서 ‘혼례를 전제로 하는 관례’를 올린 세대는 50세대 가운데 12세대, 14회였다. 하계마을 이황의 후손들은 이황의 손자 안도에 이어 1960년대까지정혼을 한 다음 관례를 올리는 전통을 이어왔다는 것을 확인할 수 있었다. 이휘연의 관례(1810년 추정)로 부터 이동후의 관례(1962년)는 19세기에서20세기 전반에 해당되는 시기에 시행되었다. 이 시기는 일제강점기라는 민족적인 수난을 겪으면서 신분제 사회의 변동과 함께 유교적 전통사회가 해체되는 시기였다. 하계마을에서 근대화・산업화・도시화라는 사회적 격변기에도불구하고 ‘혼례를 전제로 하는 관례’의 전통을 이어오고 있었다는데 의의가있다. 구술자의 기억에 의하면 하계마을에서는 1955년에서 1962년까지 전통혼례를 올린 세대는 50세대 가운데 17세대이고 그 가운데 이만규가 ‘혼례홀기’ 를 사용한 경우는 7세대 12회였다. 이만규가에서 소장하고 있는 ‘혼례홀기’를빌려서 창홀을 하였다고 한다. 1962년까지 조사된 것은 그 당시 유행하던 신식결혼식으로 인해 마을에서전통혼례가 예식장 혼례로 바뀌었고 1976년 안동댐 수몰로 인해 마을이 해체되었기 때문이다. 이만규의 현손인 이동후는 혼례를 올리기 한달 전 관례를올리고 영주에 사는 봉화 금정자와 혼인하였다. 이날 이만규가 ‘혼례홀기’를사용하였다. 도산전서에 기록된 ‘혼례홀기’는 이안도와 이야순이 남긴 기록처럼 선조의 뜻에 따라 이만규가에 전해지고 있으며 그의 현손 이동후를 통해이어지고 있다. The purpose of this study is to examine how the 'Hongryeholgi’ of the Yucheon Lee Man-gyu family was implemented and inherited in Hagye Village. First of all, we looked at the implementation of the ‘Gwallye on the premise of marriage’ before holding a wedding ceremony in Hagye Village and We looked at how the "Hongryeholgi" handed down to Lee Man-gyu family was inherited and implemented in Hagye Village, focusing on "Hyangsanjip," "Hyangsan Ilgi," "Yucheonjip," and documents and oral materials handed down to Lee Man-gyu family. Hagye Village is the most typical place where Yi Hwang's descendants have inherited and developed Yi Hwang's studies for 400 years. In <Hongryeholgi>, which is included in Dosanjeonseo, the standing position of a bride and a groom in a wedding ceremony was stated as seoseowi-donghyang’rip (壻西位東向立) and budong’wi-seohyang’rip (婦 東位西向立). Such arrangements indicate seoseo-budong (壻西婦東), where the groom stands to the west and the bride stands to the east. These positions differ from the positions of a bride and a groom in dongroe’yeon (seodong-buseo (壻東婦西)) recorded in Garye of Seongri-daejeon. From the late 16th century to the early 17th century, the era when Lee Hwang actively developed his scholarship, the social structure was being transformed with the acceptance of Neo-Confucian social customs. In particular, various ceremonies based on Zhu Xi's Garye were quickly being accommodated primarily by aristocrats during this period. Lee Hwang informed his son Lee Jun by a letter that his grandson An-do celebrated the coming-of-age ceremony (gwanrye). During this period, Confucian scholars, a s expressed in Zhu Xi's Garye, held a ceremony at the age of 15 to 20, then went to the teacher's school and studied for more than one year, or more than three years on average, and then held a wedding ceremony. The customs implemented from the mid-18th century to the early 20th century tend to be reduced to the preparation process for the wedding rather than an independent ceremony. This can be seen as a weakening of the meaning of Gwanrye that had an independent status as 'Gwallye for a position'. According to records and documents, as well as anthologies and oral data, from around 1810 to the 1960s, 12 out of 50 households, 14 generations, raised the ‘Gwallye on the premise of marriage’ in Hagye Village. It can be confirmed that the descendants of Lee Hwang of Hagye Village continued the tradition of betrothal marriage followed by Lee Hwang's grandson Ando until the 1960s. The period from Lee Hui-yeon's Gwanrye (estimated in 1810) to Lee Dong-hu's Gwanrye (1962) corresponds to the period from the 19th century to the first half of the 20th century. This period was a time when Confucian traditional society was disbanded along with changes in the status system society during the national hardship of the Japanese colonial period. Despite major changes in modernization, industrialization, and urbanization, it is meaningful that the tradition of "conventional practice on the premise of marriage" has been continued in summer villages. According to the narrator's memory, among the 50 generations in Hagye Village, 17 generations had traditional weddings from 1955 to 1962, and among them, 'Hongryeholgi ' 12 times in 7 generations. It is said that the window hall was borrowed from the ‘Hongryeholgi’ owned by the Lee Man-gyu family. The investigation until 1962 is because the traditional wedding ceremony in the village changed to a wedding ceremony in the wedding hall due to the new wedding ceremony that was popular at the time, and the village was disbanded due to the submersion of the Andong Dam in 1976. Lee Man-gyu's great-great-grandson, Lee Dong-hu, held gwanrye a month before the wedding ceremony and married Bonghwa Geumjeongja, who lived in Yeongju. On this day, ‘Hongryeholgi’ was used. The tradition of ‘wedding holgi’ has been handed down...
