The spontaneous defecation of the surgical retained sponge is very rare. Here, we report a case of migrating surgical sponge that was retained in the colon and it was evacuated by defecation.

<물결21 코퍼스>는 2000년도 이후에 발간된 국내 4대 일간지의 신문 기사를 정제한 자원으로, 2014년도 현재 6억 어절 규모의 방대한 말뭉치이다. 이러한 자원을 이제 웹 등을 통해 공개하기로 하였다. 본 논문에서는 공개와 관련한 기본 방침과 취지를 논하고 말뭉치의 정제 과정, 특징, 세부 공개 내용 등을 기술한다. 또한 실제 웹 접속 화면의 관련 기능들을 항목별로 설명하면서 공개된 웹 사이트를 구축하는 과정에서 고려된 여러 활용 방법들을 소개한다. 이러한 규모의 정제된 한국어 자원이 공개되어 연구에 활용된 예가 없다는 점과, 또한 다양한 관점에서 시대의 흐름을 조망해 볼 수 있는 중요한 자원이라는 점이 이번 <물결21> 자원 공개의 가장 큰 의의라 할 수 있고, 이는 추후 다양한 형태의 연구에 기여할 수 있다고 본다.

OBJECTIVE: The aim of this study was to describe magnetic resonance imaging findings of newly categorized ovarian seromucinous tumors. METHODS: We retrospectively reviewed the images of 29 patients with seromucinous tumor for the following factors: size, configuration, signal intensity (SI), and accompanying ovarian endometriosis. RESULTS: Thirty-two tumors (17 benign, 7 borderline, 8 carcinoma) were found on computed tomography or magnetic resonance imaging. Their mean size was 11.4 cm. Benign

Ectopic stomal varices are an unusual cause of gastrointestinal hemorrhage. The term "ectopic stomal varices" means abnormally dilated veins that have developed in the stomal mucosa. We describe the 2D reformatted and 3D volume rendered images by MDCT in a patient with an episode of acute bleeding from the colonic stoma. This case indicates that the 2D reformatted and 3D volume rendered images are useful to detect this rare complication of portal hypertension, and they help to tailor adequate tr

The spontaneous defecation of the surpical retained sponge is very rare. Here, we report a case of migrating surgical sponge that was retained in the colon and it was evacuated by defecation.

This paper is a survey of recent trends in the corpus related linguistic studies, adding two specific cases of such research as a way to illustrate how corpora can contribute to the efforts of finding interesting distributional patterns of language. We first start in Section 1 with the question if Corpus Linguistics is popular at all in the first place and some ways to find the answer, suggesting that the ‘Google N-gram viewer’, based on the N-gram data collected from the very large corpus, prov

In this study, we report on a set of experimentations for, and a successful completion of, the automatic topic classification of 3286 English essays (YELC) written by college level English learners in Korea. We adopted Hierarchical Agglomeration Clustering for our purpose. In order to find the best combination of distance measures and algorithms for hierarchical clustering, we first selected 100 essays, and then calculated precision rate on the basis of the subset of essays for each of the 15 co

This study measures the possible influence of the speakers‘ background on their acceptability judgements on Korean sentences. In total 287 pairs of sentences were used as the input sentences for the experiment. 328 Korean speakers participated in the experiment, assigning roughly 120 pairs per subject. Using z-transformation, both parametric and nonparametric tests as well as both ANOVA and multi-factor parametric statistics are applied to the data. The findings indicate that the variable FAMILI

The advent of some practical Artificial Intelligence (AI) applications and the wide availability of Deep Learning algorithms seem to have shaken most aspects of everyday life. In particular the arrival of the vector space modelling based on word embedding, and the availability of the tools like Word2vec signalled the era of high quality word vectors and literally have changed the world of Natural Language Processing. In this paper we discuss the nature of the vector space model as an alternative

In this paper, we propose a statistical method to compare a word classification system with another in terms of their mutual similarity or dependence. In particular we compare two extensive classification systems of Korean adjectives, and the question we address in this paper is if those two systems are similar or dependent to each other or not. In order to verify the similarity or relevance, we make use of the χ2 test and conclude that there is no evidence to reject the null hypothesis that the

Syntax in Japanese and Korean shows "striking similarities" especially when we consider that despite various efforts to find the historical link between the two languages any direct connection still is not well established. Such similarities also pertain in the way two nouns (phrases) are combined to form a larger nominal expression. However, when we take a careful look into the distribution and relative frequency of adnominal constructions with particles '-no' and '-ui', we notice an interestin
