Conditional-and Constructions: A Construction-based Approach

( Juyeon Cho ) 한국언어정보학회 2017 언어와 정보 Vol.21 No.2

In this paper, I argue that the conditional-and construction is a combination of a subordinating clause and a main clause, to be compatible with the syntax and semantics of the construction. In the literature, the structure for the conditional-and construction has not been proposed separately from the coordinate construction, although the researchers noted that the conditional-and construction shares a number of properties with if-conditional rather than coordinating-and construction. Unlike the previous analyses, this study claims that the conditional-and construction is syntactically a subordinate structure and treats the conditional conjunction as a main clause marker, independent of its coordinating counterpart. In specific, I propose the new constructional types conditional-conj(unction)-cl(ause) and conditional-and-cl within a construction-based HPSG framework. What I propose can account for the syntactic and semantic properties without positing any non-standard syntactic mechanism. Moreover, it deals with other relevant constructions with the conditional conjunction, by suggesting the subtypes under the unified constructional organization. (Seoul National University)

Metastatic hepatocellular carcinoma in the maxilla and temporal bone: a rare case report

Juyeon Cho 대한구강악안면외과학회 2021 대한구강악안면외과학회지 Vol.47 No.3

Hepatocellular carcinoma (HCC) is a common, primary malignant liver disease that usually metastasizes to the lungs, followed by the abdominal lymph nodes and brain. However, extrahepatic metastasis to the maxillofacial area is uncommon and predominates in the mandible, so HCCs in the maxilla or temporal bone from a primary hepatic lesion are extremely rare. We present a case of HCC in the maxilla and temporal bone in a 52-year-old male, which was first suspected to be a squamous cell carcinoma after computed tomography but was confirmed as a metastasis related to his primary HCC after fine-needle aspiration biopsy followed by immunohistochemical analysis.

Cemento-osseous dysplasia in need of careful examination : a case report

Juyeon Cho(조주연) 대한치과의사협회 2022 대한치과의사협회지 Vol.60 No.11

Cemento-osseous dysplasia (COD) is a fibro-osseous lesion of the maxilla and mandible, originating from a periodontal ligament. It resembles a periapical lesion such as a periapical abscess or a cyst in its early stage. Usually, the affected tooth : is vital and without symptoms. A healthy 35-year-old female was referred to the endodontic department for evaluation and endodontic treatment of an amalgam restored mandibular first molar with an apical radiolucency. Since the tooth was sensitive to a cold stimulus, chronic apical periodontitis was suspicious at first sight. But after clinical and radiographic evaluations, multiple periapical COD involving vital teeth of the mandible was diagnosed. No specific treatment of COD was scheduled except for renewing the pre-existing restoration. The present case is a confusing case since COD was associated with an asymptomatic tooth. Knowledge of the clinical features related to pulp vitality tests and cone-beam computed tomography (CBCT) helps determine the differential diagnosis between COD and a periapical lesion.

A Corpus-based Approach of Indefinite Relative Pronoun Whatever : from Old English to Early Modern English

Juyeon Cho 한국언어과학회 2015 언어과학 Vol.22 No.4

The purpose of this paper is to investigate the indefinite relative pronoun whatever using the Helsinki Corpus of English Texts. The variants of whatever can be distinguished into three general groups: swa…swa, …se and …(so)ever. The usages of the form swa…swa were mostly observed in the Old English period and gradually declined during the Middle English period when they were replaced by the form …se. The form …se was not used for a long time and the form …ever appeared from the late Middle English period. The variants of whatever were mostly treated as a pronoun, adjective and adverb. Among them, this paper focuses on the pronoun and adjective with indefinite relative sense. Leading the indefinite relative clause, the word whatever as a direct object appeared most frequently in the Old English and Middle English period and as a subject in the Early Modern English period.

자율주행차량은 다양한 센서를 기반으로 주변 상황을 인지하며 주행한다. 특히 차도에 존재하는 차선정보는 차량이 이동해야 할 방향을 결정해주는 중요한 정보다. 그러나 도심지 도로에서는 다양한 장애물과 복잡한 도로 마커로 인해 Rule 기반의 이미지 처리기법의 차선검출 방법으로는 한계점이 존재한다. 따라서 본 논문에서는 카메라를 통해 얻은 이미지 정보를 딥러닝 알고리즘과 이미지 프로세싱 기법을 통한 차선영역 검출의 기법을 동시에 적용하고, 칼만필터를 이용하여 강건하게 차선을 검출할 방법을 제안하고자 한다. 알고리즘의 전체 도식도는 그림 1의 좌측과 같이 표현할 수 있다. 복잡한 도로 환경에서 차선영역만을 추출하기 위해 사용한 딥러닝 네트워크는 LaneNet 알고리즘을 사용하였고, 그림 1 우측 상단과 같이 네트워크에서 마스크 네트워크만을 이용하였다. LaneNet 이미지결과를 통해서 거리계산을 위한 bird-eye-view, Homography 변환 과정을 진행하여 도로 영역에서의 좌표변환과정을 수행하였다. 또한 전처리 과정을 통해 추출한 Binary 형태의 이미지에서 Hough line detection 알고리즘을 통하여 좌측, 우측이라고 예상하는 차선을 추출하고 초기 Sliding window를 생성하여 LaneNet 결과 이미지에서 탐색을 수행하게 된다. 이미지에서 좌측, 우측 차선의 탐색이 종료되면 각 차선의 해당하는 픽셀 좌표를 저장하고 노이즈를 고려하여 RANSAC 알고리즘과 최소자승법을 이용한 3차 방정식의 차선정보를 얻을 수 있다. 마지막 단계로 좌측, 그리고 우측 차선에서 얻은 차선의 정보를 Clothoid road model기반의 칼만필터를 적용하여 강건한 차선추출을 진행하게 되며, 그림 1 우측 하단 그림과 같이 좌측, 우측 차선이 검출되는 것을 확인할 수 있다.

Purpose: The purpose of this study was to investigate the relationship between clinical practice stress, teaching effectiveness and clinical practice satisfaction of nursing students and to clarify the effect on clinical practice satisfaction. Method: Data were collected from 211 nursing students. Statistical analysis of independent t-test, ANOVA, Pearson’s correlation coefficients, and multiple regression analysis was performed through the SPSS 25.0. Results: The mean score for clinical practice stress was 3.22 (±0.51), for teaching effectiveness, 3.47 (±0.58), and for clinical practice satisfaction, 3.38 (±0.52) on a 5-point scale. The relationship between teaching effectiveness and clinical practice stress (r=-.26, p<.001), clinical practice stress and clinical practice satisfaction (r=-.36, p<.001) showed a significant negative correlation. The relationship between teaching effectiveness and clinical practice satisfaction (r=.70, p<.001) showed a significant positive correlation. The predictors on clinical practice satisfaction were teaching effectiveness, clinical practice stress, health status and grade. Our model explained 54.6% (F=64.154, p<.001). Conclusion: The finding of the study suggest that teaching effectiveness, clinical practice stress, health status and grade be considered when developing strategies to increase clinical practice satisfaction in nursing students.

Purpose: This descriptive study aims to examine the factors that influence nursing students' adaptation to clinical practice. Methods: Data were collected using questionnaires from 218 nursing students who were 3rd and 4th years of college. The data were analyzed using the SPSS/WIN 29.0 program with descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficients, and hierarchical multiple regression. Results: Clinical practice adaptation showed a positive correlation with grit(r=.34, p<.001), integrating(r=.32, p<.001), and compromising(r=.20, p=.003), and a negative correlation with avoiding(r=-.17, p=.013). As a multiple regression analysis, the factors significantly influencing the adapta-tion to clinical practice were satisfaction with clinical practice, satisfaction with the nursing department, perseverance of ef-fort, use of integrating and motivation of major selection(attitude), and total explanatory power was 41.8% (F=10.73, p<.001). Conclusion: To improve nursing students' adaptation to clinical practice, efforts in nursing education to increase satisfaction with clinical practice and major, recognition of the importance of grit, development and application of programs to improve grit, using conflict resolution strategy, and activation of systematic career exploration education are required.

A Role for Peroxidasin PXN-1 in Aspects of C. elegans Development

Lee, Juyeon,Bandyopadhyay, Jaya,Lee, Jin Il,Cho, Injeong,Park, Daeho,Cho, Jeong Hoon Korean Society for Molecular and Cellular Biology 2015 Molecules and cells Vol.38 No.1

The Caenorhabditis elegans peroxidasins, PXN-1 and PXN-2, are extracellular peroxidases; pxn-2 is involved in muscle-epidermal attachment during embryonic morphogenesis and in specific axon guidance. Here we investigate potential roles of the other homologue of peroxidasin, pxn-1, in C. elegans. A pxn-1 deletion mutant showed high lethality under heat-stress conditions. Using a transcriptional GFP reporter, pxn-1 expression was observed in various tissues including neurons, muscles, and hypodermis. A translational fusion showed that PXN-1::GFP was secreted and localized in extracellular matrix, particularly along body wall muscles and pharyngeal muscles. Various neuronal developmental defects were observed in pxn-1 mutants and in pxn-1 over-expressing animals, including handedness, branching, breakage, tangling, and defasciculation. These results suggest that pxn-1, like other peroxidasins, plays an important role throughout development.
