Lexical Meanings with Respect to Metaphor and Syncategorematic Modifiers

Lee, Heechul 대한언어학회 2000 언어학 Vol.8 No.2

Lee, Heechul. 2000. Lexical Meanings with Respect to Metaphor and Syncategorematic Modifiers. Linguistics 8-2, 25-41. One of the metaphorical mappings Lakoff and Johnson (1980) consider is Theories are Buildings. This paper will construct detailed mappings that characterize this metaphor. It is necessary to actually "get our hands dirty" and study one metaphor in detail to really understand the theory. The paper will set up mappings for this analysis in a particular and explicit way, building upon the analyses presented in Lakoff and Johnson (1980) for the metaphor of Love is a journey. It has frequently been discussed (e.g., Austin 1964) that a word like imitation does not semantically modify a noun in the standard 'set intersection' way. For example, something correctly described as imitation coffee looks and tastes like coffee; but, whatever it is, it is not made of coffee beans. (Fillmore 1982: 133) The second half of this paper will discuss the so-called syncategorematic terms like imitation, which do not work like other noun modifiers. (Chonbuk National University)

A Study on Some Korean Classifiers with Respect to Cognitive Semantics

Lee, Heechul 대한언어학회 1998 언어학 Vol.6 No.2

Lee, Heechul. 1998. A Study on Some Korean Classifiers with Respect to Cognitive Semantics. Linguistics, 6-2, 83-101. Three numeral classifiers (NC's, henceforth) will be discussed in this paper, one of which is ssang,^1) another khyelley, and the last pet, along with coak and ccok related to those classifiers. Intuitively speaking, the first two numeral classifiers are used to count two separate entities as a unit, and the last one is used to count two or more entities as a unit. Nouns that go with either ssang or khyelley are assumed to denote a unit of two entities on their own right in a default case. pel will be discussed separately later. ssang is Sino-Korean whereas khyelley and pel are native Korean.

Frame Semantics, Idealized Models, and Category Structure

Lee, Heechul 대한언어학회 1999 언어학 Vol.7 No.1

Lee, Heechul. 1999. Frame Semantics, Idealized Models, and Category Structure. Linguistics, 7-1, 127-138. Jackendoff (1989) contains an analysis of the meaning of the verb climb in terms of preference rules. In such an analysis, we can define a given use of a word as more 'prototypical' if more of the "preference rules" are satisfied in the situation in which the word is used. In his two frame semantics articles, Fillmore (1982, 1985) suggests another analysis of 'prototype effects' of the kind Rosch (1981) studies. The question in part of this paper is, what would be the analysis of climb in a frame semantics approach? How does it account for the relative prototypicality of the uses of the word climb? The point of another part of this paper is to help people understand the category better. It takes an idealized model and define rape with respect to this model as Sweetser (1987) dig for lie. Sweetser's (1987) article shows an example of a concept being defined relative to an idealized model, namely, the concept of lying. Sweetser (1987) ????ons that modifiers of the noun lie are typically used to indicate that some of the conditions which hold of the idealized model do not hold of, tie situation under discussion. Part of this paper attempts to provide a similar' analysis for rape. (Chonbuk National University)

Heechul Kim,Eunbee Lee,Songhyeon Kim,Eungyeong Lee,Jeongmin Yun,Seonjeong Kim,Changil Lee 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

This study investigated whether apple blossoms are functional as a cosmetic material. In this study, Crap apple, Hong-ro, Summer king, and Fuji varieties were used as samples. For each sample, general component analysis and functional tests were conducted, and total phenol contents, DPPH, ABTS, and PF tests were performed to find out antioxidant activity as functional tests. As a result of analyzing the general components of apple blossom, crude carbohydrates were 8.321∼11.425%, crude protein was 3.919∼4.724%, crude fat was 2.902∼3.430%, crude ash was 1.141∼1.218%, and moisture was 79.959∼83.112%. DPPH is 3.25% (25 μg/mL), 6.48% (50 μg/mL), 13.54% (100 μg/mL), ABTS is 10.77% (25 μg/mL), 23.16% (50 μg/mL), 45.60% (100 μg/mL), Crap apple showed the highest antioxidant activity. Also, the total phenol content was 173 mgGAE/g, which was the highest in the Crap apple sample. However, there was no significant difference in the PF values indicating the fat-soluble antioxidant activity among apple blossom varieties.

온라인 크라우드소싱 플랫폼을 통해 수집된 빅데이터를 활용한 텍스트마이닝은 최근 다양한 분야에서 빠르게 성장하고 있는 분석방법론이다. 이 연구는 온라인 정책제안 플랫폼인 광화문1번가에 수집된 데이터를 다양한 텍스트마이닝을 통하여 시민들이 제안한 의견 속에서 도시계획 정책 이슈를 도출하고 협력적계획의 상향식 접근법 측면에서 정책적 시사점을 제시하는 것을 주요 목적으로 한다. 이를 위해서 총 6,994개의 제안에서 명사만을 주요 분석대상으로 삼았으며, 키워드와 네트워크 분석을 수행하였다. 키워드 분석결과 시민들의 주요 고민은 주택, 토지, 교통 정책과 관련된 키워드로 나타났고, 연어 분석결과는 임대료와 도시개발과 같은 주택정책에 대한 내용을 확인할 수 있었다. 네트워크 분석을 통하여 정책이슈를 공유하는 지역커뮤니티를 도출하였고, 그 결과는 지리적으로 가깝거나 혹은 주요 이슈를 공유하는 특성을 보였다. 온라인 플랫폼을 통해 수집된 정책제안 데이터의 텍스트마이닝을 통해 도시민들의 주요고민을 키워드 중심의 이슈로 도출하고, 유사한 이슈를 공유하는 지역을 밝힘으로써 협력적계획과 의사결정과정에서의 활용가능성을 보였다는 점에서 연구의 의의가 있다. Text mining of big data generated through online crowdsourcing platforms has emerged as a rapidly growing field in research. In line with collaborative planning, this study took a bottom-up approach to examining people’s ideas about urban and regional planning: Text mining was used to analyze data crowdsourced from an online forum, Gwangwhamoon 1st Street, to identify Korean citizens’ policy suggestions. Noun words as the target dataset were extracted from 6,994 suggestions, and keyword and network analysis were conducted. The keyword analysis revealed that Koreans’ main concerns and interests related to housing, land, and transportation policies. The network analysis revealed co-occurring keywords, indicating common policy suggestions about housing policies. Networks of specific regions were also examined, resulting in ten communities grouped by physical distance or similar regional problems. The findings of this study can help experts and government officials identify the main concerns of residents in Korea and develop cooperative systems across municipalities, thereby improving policy-decision process in the fields of urban and regional planning.

Automatic illumination and color compensation using mean shift and sigma filter

Heechul Han,Kwanghoon Sohn IEEE 2009 IEEE transactions on consumer electronics Vol.55 No.3

<P>We present a novel framework for automatic illumination and color compensation algorithm using mean shift and the sigma filter (ICCMS) to restore distorted images taken under the arbitrary lighting conditions. The proposed method is effective for appropriate illumination compensation, vivid color restoration, artifacts suppression, automatic parameter estimation, and low computational cost for HW implementation. We show the efficiency of the mean shift filter and sigma filter for illumination compensation with small sized kernel while considering the processing time and removing the artifacts such as HALO and noise amplification. The proposed color restoration function can restore the natural color and correct color noise artifact more perceptually compared with conventional methods. For the automatic processing, the image statistics analysis estimates suitable parameter and all constants are pre-defined. We also introduce the ROI-based parameter estimation dealing with small shadow area against spacious well-exposed background in an image for the touch-screen camera. The object evaluation is performed by CMC, CIEde2000, PSNR, SSIM, and 3D CIELAB gamut with state-of-the-art research and existing commercial solutions.</P>

Aims: Antiviral therapy improves hepatic fibrosis and reduces hepatocellular carcinoma (HCC) incidence. This study aimed to evaluate whether on-therapy changes in scores for fibrosis index based on four factors and aspartate aminotransferase-to-platelet ratio index are associated with HCC development and establish an HCC risk score model incorporating non-invasive fibrosis marker (NFM) response. Methods: This multi-center study recruited 5147 chronic hepatitis B patients (4028 for derivation cohort, 1119 for validation cohort) who were given Entecavir/Tenofovir for >12 months between 2007 and 2018. A risk prediction model for HCC was developed using predictors based on multivariable Cox models and bootstrapping was performed for validation. Results: The 10-year cumulative HCC incidence rates were 12.6% and 13.7% in the derivation and validation cohorts, respectively. The risk of HCC significantly differed with early NFM response, with a marked reduction in HCC risk in patients achieving a significant decrease in NFM by 12 months (P<0.001). Sex, age, cirrhosis, and NFM response were independently predictive of HCC, and the FSAC model was developed based on these variables. For the 10-year prediction of HCC, FSAC showed higher c-index values than PAGE-B, CU-HCC, and REACH-B (0.84 vs. 0.76, 0.77, and 0.67, respectively; all P<0.001). The predictive performance of FSAC was corroborated in the validation cohort, with higher c-index than other models (all P<0.050). Conclusions: On-therapy changes in NFM are an independent indicator of HCC risk. FSAC incorporating NFM response is a reliable risk score for risk estimation for HCC with better performance than other models.

How to Use Semantic Features in Teaching (Non-) Factive Verbs

( Heechul Lee ),( Jaewoo Shim ),( Hanna Kim ) 전북대학교 인문학연구소 2020 건지인문학 Vol.0 No.28

The purpose of this study is to find out what kinds of verbs learners found most difficult to use precisely among factive and non-factive verbs and to suggest teaching strategies that will help them to use those confusing verbs correctly. In this study, nine semantically confusing verbs, ‘point out’ and ‘say’, ‘show’ and ‘suggest’, ‘claim’, ‘insist’ and ‘argue’ and ‘doubt’ and ‘suggest’ were selected among factive and non-factive verbs. The findings of the study and the implications are the following: 1) Between factive and non-factive verbs, participants were poor at distinguishing non-factive verbs ‘suggest’ and ‘say’. When teaching these verbs, it should be emphasized that they cannot take clauses which prove to be true but clauses which are based on one’s belief. 2) Between non-factive verbs ‘claim’ and ‘insist’, subjects found ‘claim’ more difficult to use correctly. When teaching about this verb, the focus should be on its [NON-EVIDENT] element. 3) Between non-factive verbs ‘suspect’ and ‘doubt’, participants considered ‘suspect’ more challenging to use precisely. When teaching about the verb, a [believe] element should be considered.
