의미 역 결정 (Semantic Role Labeling)은 문장의 각 요소들의 의미 관계를 파악하는 연구 분야로써 어휘 중의성 해소와 더불어 자연언어처리에서의 의미 분석에서 매우 중요한 위치를 차지하고 있다. 그러나 한국어의 경우에는 의미 역 결정에 필요한 언어 자원이 구축되지 못하여 연구의 진행이 매우 미진한 상황이다. 본 논문에서는 의미 역 결정에 필요한 언어 자원 중에서 가장 널리 사용되고 있는 PropBank의 한국어 버전의 구축을 위한 시작 단계로써 자동 술어-논항 분석기를 개발하였다. 자동 술어-논항 분석기는 크게 의미 어휘 사전과 자동 술어-논항 추출기로 구성된다. 의미 어휘 사전은 한국어 동사의 격틀 정보를 구축한 사전이며 자동 술어-논항 추출기는 구문 표지 부착된 말뭉치로부터 특정 술어와 관련있는 논항의 의미 부류를 결정하는 모듈이다. 본 논문에서 개발된 자동 술어-논항 분석기는 향후 한국어 PropBank의 구축을 용이하게 할 것이며, 궁극적으로는 한국어 의미 역 결정에 큰 역할을 할 것이다. Semantic role labeling is the research area analyzing the semantic relationship between elements in a sentence and it is considered as one of the most important semantic analysis research areas in natural language processing, such as word sense disambiguation. However, due to the lack of the relative linguistic resources, Korean semantic role labeling research has not been sufficiently developed. We, in this paper, propose an automatic predicate-argument analyzer to begin constructing the Korean PropBank which has been widely utilized in the semantic role labeling. The analyzer has mainly two components: the semantic lexical dictionary and the automatic predicate-argument extractor. The dictionary has the case frame information of verbs and the extractor is a module to decide the semantic class of the argument for a specific predicate existing in the syntactically annotated corpus. The analyzer developed in this research will help the construction of Korean PropBank and will finally play a big role in Korean semantic role labeling.

최근 문서 저작권에 대한 관심과 중요도가 높아지고 있어 문서 표절에 관한 연구가 지속적으로 이루어지고 있다. 이러한 표절 문제는 신문기사의 경우에서도 큰 관심을 끌고 있는데, 이는 상업적 가치가 큰 기사의 표절 또는 무단도용 문제가 적지 않게 발생하고 있기 때문이다. 현재까지의 문서 표절 관련 연구는 실시간 특성이 매우 강한 신문 기사의 표절 문제에 적용하기 어려웠다. 따라서 현재는 이러한 표절 기사를 가려내기 위해 수백 개의 신문사에서 하루 수천 건씩 올라오는 기사들을 눈으로 일일이 가려내는 상황이다. 본 논문에서는 이러한 시간과 비용의 문제를 줄이기 위해 네이버와 다음에서 제공하는 웹 검색 OpenAPI를 활용해 표절 가능성이 있는 기사들을 1차적으로 선별한 다음, 선별된 기사들과 원본 기사와의 문서 유사도를 측정하여 선별된 기사들의 표절 여부를 자동으로 판정할 수 있도록 하였다. 본 연구에서는 실험을 위하여 연합뉴스에서 제공되는 기사를 원본 기사로 활용하였고, 표절 가능성이 있는 기사는 네이버 및 다음의 뉴스 서비스에서 제공되는 모든 기사 중에서 선별하도록 하였다. With the increased interest on the document copyright, many of researches related to the document plagiarism have been done up to now. The plagiarism problem of newspaper articles has attracted much interest because the plagiarism cases of the articles having much commercial values in market are currently happened very often. Many researches related to the document plagiarism have been so hard to be applied to the newspaper articles because they have strong real-time characteristics. So to detect the plagiarism of the articles, many human detectors have to read every single thousands of articles published by hundreds of newspaper companies manually. In this paper, we firstly sorted out the articles with high possibility of being copied by utilizing OpenAPI modules supported by web search companies such as Naver and Daum. Then, we measured the document similarity between selected articles and the original article and made the system decide whether the article was plagiarized or not. In experiment, we used YonHap News articles as the original articles and we also made the system select the suspicious articles from all searched articles by Naver and Daum news search services.

Resident participation plays much of a rule to the cohousing, which is organized independently and has the characteristics of community life, especially in the initial state of cohousing process. However, it is hard to realize the resident participation in proper order due to lack of a personal time, individual effort and an insufficient knowledge related with cohousing. So, it is thought that the guidance of cohousing expert and coordinator is needed to enable the residents to perform in an active attitude. The development of educational program and workshop connected with resident participation is also accompanied. In this study, to make the positive and systematic participation of cohousing residents, we established the workshop program and performed workshop with our developed program, based on preceding researches and examples. We selected the object of workshop as five housewives in thirties and forties. Workshop was consisted of six process steps. (1) Introduction and question of workshop and cohousing (2) examining and arranging the opinion (3) Master plan of cohousing village (4) Planning of common living space (5) Planning of individual living space (6) Analysis of final results and evaluation of workshop. The workshop held six times and it took about five~six hours per each meeting. Workshop participants expressed their opinion actively and attended in a positive manner in order to the design of their desired village and cohousing. During workshop process, the players established the common target of their village by means of life card, target card game. Also, based on the common target, the layout of village was planned using a collage game and card arrangement game. By workshop activity, the members started to recognize the significance of participation on the drawing board and improve their technique of communication and decision-making. Furthermore, workshop process made it possible to approach the concrete forms of their cohousing village. Especially, in the closing phase, the participant satisfaction about workshop and cohousing is increased suddenly and expressed their intention to join the real workshop related with cohousing.

조정현,배범한,김계훈,Cho, Jung-Hyun,Bae, Bum-Han,Kim, Kye-Hoon 한국지하수토양환경학회 2009 지하수토양환경 Vol.14 No.1

HPLC에 의한 토양내 화약물질의 분석 방법을 최적화하기 위해 현재 실사격 훈련이 진행 중인 군사격장 2곳에서 토양시료를 채취하여 분석 실험을 수행하였다. 토양과 오염물질의 불균일도를 감안하여 segregation constant 와 homogeneity constant를 기준으로 산정한 결과, 화약물질의 분석을 위한 토양시료채취 최소량은 125g 이었다. 그리고 시료 전처리 과정인 추출단계에서 필요한 적정시료량과 추출액의 비율을 CV값에 근거하여 산정한 결과 토양 10g/ACN 20 mL가 가장 효과적이었다. 미국 EPA에서 지정한 화약물질 14종을 모두 분리하기 위한 HPLC의 용리 조건은 RP C18캘럼을 이용하여 칼럼온더 30${\circ}C$일 때, 이동상 구성 및 유량은 isopropanol : acetonitrile : water의 비율 18 : 12 : 70, 유량 0.80mL/min인 경우가 최적이었다. 분석파장 결정을 위해 분석 파장 230nm와 254nm에서의 화약물질 14종에 대한 검출한계 (detection limit)값과 각 화약물질의 UV/VIS스펙트럼을 비교한 결과 254nm보다 230nm일때가 더 적절하였다. 하지만 NB, 2,4-DNT, 2NT, 4NT및 3NT는 분석파장이 UV254nm일때 더 적절하였다. A series of experiments was performed to develop an optimized analytical procedure for the analysis of explosives in soil by HPLC with soil samples collected at two live-fire military shooting ranges. The minimum amount of soil to be collected, Wmin, for the analysis of explosive compounds was 125g, based on the segregation and homogeneity constants that account for soil heterogeneity and non-homogeneous distribution of target explosive compounds. The optimization of extraction and HPLC analytical conditions were also studied based on analytes CV values. The most effective soil/ extractant ratio was estimated to be 10g-pretreated soil/20 mL acetonitrile as extractant. The optimized HPLC elution conditions for the separation of US EPA designated 14 explosive compounds, were column temperature 30${\circ}C$, eluents ratio of isopropanol: acetonitrile: water = 18 : 12: 70, and flow rate of 0.8 mUmin at 230 nm. However, UV wavelength 254 nm was better for the analysis of NB, 2,4-DNT, 2NT, 4NT, and 3NT.

Since the cohousing idea, originated in Northern Europe, was introduced in the U.S. by architects Kathryn McCamant and Charles Durrett in the early 1980s, there are recently the largest number of cohousing communities and rapidly expanded in the U.S. So, it is necessary to appreciate the cohousing communities developed in U.S. In this study, we investigated the physical characteristics of cohousing and the methods of its residents' participation by means of a case study on cohousing communities in U.S. and suggested the future direction of the cohousing community. Also, this work could be exploited when the cohousing is introduced to Korea. At first, the general status and characteristics of U.S cohousing was explored using diverse sources such as literature, paper and Web site. And then, the direct visit survey was used to obtain the more exact and specific data about physical aspects and residents' participation in each community. We found that cohousing communities were mostly located in the urban and Rural area, which was founded in the 1990s, and new communities continue to be created in the U.S. Typically, the number of households is from 20 to 30 in one community. The land is generally owned by the community itself and its size is within 10 acres. Communities usually serve optional group meals in the common house at least two or five times a week. Each member's income is separated and the community members should take care of their common properties. The leader of community does not exist and most communities don't have the organization of community members. All cohousing communities use consensus as the basis for group decision-making.

This is a basic study to investigate possibility to application of cohousing model into Korea. Purpose of this study is to grasp respondents' housing value, and its influence on intention to live in cohousing. Research method used for this study was a social survey. Respondents were 214 married people residing in Seoul and its outskirts by accidential sampling. The collected data were analyzed by SPSS 12.0 program using frequency, mean, average, factor analysis, t-test, one-way ANOVA, Duncan's multiple range test, multiple regression and legit analysis. Result of this study was as follows. Housing values were classified into three categories named as individualism oriented housing value, tradition oriented housing value, and economy oriented housing value. Housing values were different by respondents groups. For example, individualism oriented housing value showed difference according to age and housing area. Tradition oriented housing value showed difference according to sex, occupation, and period of residence, while economy oriented housing value showed difference according to housing type, and home ownership. In detail, men than women, single-income family than double-income family, and detached house resident than flat resident had higher tradition oriented housing value. The younger than the elder, and Seoul resident than outskirts resident had higher economy oriented housing value. Also home owner than tenant, and the higher tradition oriented group had stronger intention to live in cohousing than others.

마을공동체 제의 관련 유무형 공유자원의 형성과정과 전승양상

조정현(Cho, Jung-Hyun) 비교민속학회 2015 비교민속학 Vol.0 No.56

이 논문에서는 마을공동체 제의가 역사적 전개과정 속에서 어떻게 유무형의 공유자원을 확보해왔고 이것이 마을사회 속에서 어떻게 변화되어 왔는지를 농촌, 어촌, 산촌으로 구분하여 살펴보려 하였다. 의식주의 빈곤 속에서도 마을굿이라는 중핵을 중심으로 동토 혹은 위토를 마련하거나 다중의 압력을 통해 마을과 인근지역의 지배세력으로부터 후원을 이끌어낸 농촌과 산촌, 지선어장과 짬이라는 해양자원을 마을굿의 중요한 공유자원으로 확보하고 다양한 운용방식을 창출해온 어촌 등의 사례를 통해 구체적으로 밝히고자 한다. 결국 이 연구는 마을공동체의 제의 관련 공유자원 형성과 전승 양상을 구체적으로 파악하고 마을 유형별 사례를 살펴보고자 한 것이다. 또한 여전히 정립되지 못한 한국적 사회자본의 문제를 마을공동체 제의와 연계시켜 논의하고 ‘유무형 공유자원’의 맥락과 대조해가면서 한국적 사회자본의 향방을 제시하고 향후 이론으로 발전시킬 수 있는 토대를 마련하고자 하였다. 또한 현지조사와 분석을 통해 제의 관련 유무형 공유자원이 어떻게 활용되면서 마을사회를 변화시켜왔는지를 살피고자 하였다. A tangible and intangible village-shared resources of in connection with maeul gut has formated and transmitted in agricultural area, mountain area and coast area. Such transmission of byulshin-gut and dongje which are the central axis of the identity of the fishing village. The tradition of natural redistribution through maeul gut for residual goods formed through operation of villageshared resources is now endangered. The redistribution of shared resources is the operation principle of the community that must stand strong in any area and any era, but it failed to be exercised smoothly, and the conflict was only growing greater. After all, each ritual groups include rural district, a mountain village and a sea village, can said to have the proper functions as a transmission group of community faith and also the adverse effects as an exclusive interest group within the village. As a social organization transferred down from the traditional society, it should have been a exemplary model for beautiful and fine customs, but in reality, it shows the aspects of an interest group of a few individuals armed with capitalistic spirit. In a fishing village which is often considered to have a community spirit different from the city and also with beautiful customs and thus be slow to be capitalized, in a way, one can observe the most capitalistic thinking and actions taking place. The aspects of ritual group and maeul gut are explicit mirrors of Korean society reflecting the rapid changes in Korean society and the reality of its side effects.

본 증례는 가족력 및 다른 특이 질환이 없는 환자에서 발생한 지속성 atrial standstill을 영구적 인공 심박동기를 시술하여 치료하였기에 이제까지 국내에서는 증례보고가 없는 바 문헌고찰과 더불어 보고하는 바이다. Persistent atrial standstill is an extremely rare arrhythmia that was first described by Chavez et al. Electrocardiographically, atrial standstill is characterized by bradycardia, the absence of a P wave, and a junctional narrow complex escape rhythm. Atrial standstill is usually classified into two types. The transient type is observed in drug intoxication, such as with digitalis or quinidine, and hyperkalemia. The persistent type is uncommon, often accompanied by syncopal attacks or brain embolism. We report a case of persistent atrial standstill in an 83-year-old man who was treated with implantation of a permanent pacemaker. (Korean J Med 78:109-112, 2010)
