FAQ: Do Non-linguists Share the Same Intuition as Linguists?

송상헌,최재웅,오은정 서울대학교 언어교육원 2014 語學硏究 Vol.50 No.2

When studying the nature of human language, we frequently ask ourselvesthe following question: Do native speakers agree with our judgmentsof the sentences in question? Many of us have encountered quitea few sentences which linguists report to be grammatical but whichnon-linguists find ungrammatical. Linguists try their best in their languageanalyses to accommodate the native speakers’ intuitions in a systematicway, but these efforts are mostly confined to the so-called‘informal’ method. A natural question that arises is if the naïve nativespeakers would agree to the introspective acceptability judgments. Inorder to properly answer this question, a rigorous and formal methodthat will ensure more systematic and fine-grained results is required. This paper aims to address questions relating to this issue, exclusivelyfocusing on Korean. The present work intends to provide some substantivediscussion on how similar or different linguists’ intuitions are to/from those of the general public estimating grammatical acceptability. Our main experiment was carried out with 138 subjects, using aboutone thousand sentences excerpted from two volumes of a linguisticjournal. We calculated the convergence rate focusing on the pairwisesentences in the data, and the rate was computed to be 84.75%. Thismeasure is somewhat lower than the convergence rate of 95% reportedin Sprouse et al. (2013) for the English data.

중학생 R&E 지도 사례: NIM 게임의 필승 해법 탐구와 변형 NIM 게임 개발을 중심으로

송상헌 한국과학영재교육학회 2023 과학영재교육 Vol.15 No.1

This is a case study of R&E instruction for middle school students in Science Gifted Education Center who explored the winning solution of the NIM game, a type of two-person finite turn-based fixed complete information game, and modified the game. It is not difficult for middle school students to understand the solution of the NIM game and solve the problem while obtaining the logical sum expressed in binary. However, unlike the enrichment course, R&E education for gifted students explores new mathematical properties beyond the given problem-solving method, and experiences the rediscovery of principles, reinvention of forms, and re-creation of games through various transformations (making, development). We should be able to guide them through these methods. As a result of re-creation mathematics through recreational activities, students created a modified NIM game that extended it in addition to several known modified NIM games. The results of this study can be used for the development of modified NIM games and will be helpful for teaching R&E in the secondary school course. 본 연구는 2인 유한 턴제 확정 완전정보게임의 일종인 NIM 게임의 필승 해법의 수학적 성질을 탐구하고 그 게임을 변형한 과학영재교육원 중등수학 사사과정 R&E 지도 사례이다. 중학교 학생들 수준에서 어떤 수를 이진법으로 표기한 논리합을 구하면서 NIM 게임의 해법을 이해하고 문제를 해결하는 것은 어렵지 않다. 그러나 영재들을 위한 사사과정인 R&E 교육에서는 심화 과정과 달리 주어진 문제해결의 방법을 넘어 새로운 수학적 성질을 탐구하고 다양한 변형(만들기, 발전)을 통해 원리의 재발견, 형식의 재발명, 게임의 재창조를 경험할 수 있도록 안내할 수 있어야 한다. 레크리에이션 활동을 통한 리크리에이션 수학의 결과 학생들은 이미 알려진 몇 가지의 변형 NIM 게임 외에 그것을 확장한 변형 NIM 게임을 만들어냈다. 본 연구 결과는 변형 NIM 게임 개발에 활용할 수 있고 중등사사과정 R&E 지도에도 도움이 될 수 있을 것이다.

Different Ways to Test Acceptability Judgments

송상헌,이상근,최재웅,오은정 한국생성문법학회 2015 생성문법연구 Vol.25 No.2

The testing of acceptability judgments has recently attracted some attention in the study of syntax. This is because many linguists have come to realize that the extensive measuring the correlations between native speakers' intuitions provides a reliable way to investigate the genuine nature of human language. The growing research interest notwithstanding, the methodology of acceptability judgment experiments has not been completely validated. Since experimental syntax is an empirical science, it is important to develop a strong research methodology for a large-scale and in-depth quantitative analysis. In this context, the research question this paper raises is whether or not different methodologies of acceptability judgment testing yield different conclusions. The present study conducts two experiments that share exactly the same test items but are controlled and analyzed in different ways. Looking into the convergence rate using different methods of experimental control and statistical analysis, the present study provides four findings which can lead to a better methodology for observing native speakers’ intuitions: First, randomization is a mandatory process in acceptability judgment testing. Second, the mean in itself does not provide good statistical power in acceptability judgment testing. Third, sociological variables can affect acceptability judgments. Fourth, the size of sample in acceptability judgment testing should be more than 40 in order to yield a trustworthy conclusion.

Fibrocartilaginous Intramedullary Bone Forming Tumor of the Distal Femur Mimicking Osteosarcoma

송상헌,이한나,송해룡,김묘종,박종훈 대한의학회 2013 Journal of Korean medical science Vol.28 No.4

Fibrocartilaginous dysplasia (FCD) has occasionally led to a misdiagnosis and wrong decision which can significantly alter the outcome of the patients. A 9-yr-old boy presented with pain on his left distal thigh for 6 months without any trauma history. Initial radiographs showed moth eaten both osteolytic and osteosclerotic lesions and biopsy findings showed that the lesion revealed many irregular shaped and sclerotic mature and immature bony trabeculae. Initial diagnostic suggestions were varied from the conventional osteosarcoma to low grade central osteosarcoma or benign intramedullary bone forming lesion, but close observation was done. This study demonstrated a case of unusual fibrocartilaginous intramedullary bone forming tumor mimicking osteosarcoma, so that possible misdiagnosis might be made and unnecessary extensive surgical treatment could be performed. In conclusion, the role of orthopaedic oncologist as a decision maker is very important when the diagnosis is uncertain.

Polygenic risk score for genetic evaluation of prostate cancer risk in Asian populations: A narrative review

송상헌,변석수 대한비뇨의학회 2021 Investigative and Clinical Urology Vol.62 No.3

Decreasing costs of genetic testing and interest in disease inheritance has changed the landscape of cancer prediction in prostate cancer (PCa), and guidelines now include genetic testing for high-risk groups. Familial and hereditary PCa comprises approximately 20% and 5% of all PCa, respectively. Multifaceted disorders like PCa are caused by a combinatory effect of rare genes of high penetrance and smaller genetic variants of relatively lower effect size. Polygenic risk score (PRS) is a novel tool utilizing PCa-associated single nucleotide polymorphisms (SNPs) identified from genome-wide association study (GWAS) to generate an additive estimate of an individual's lifetime genetic risk for cancer. However, most PRS are developed based on GWAS collected from mainly European populations and do not address ethnic differences in PCa genetics. This review highlights the attempts to generate a PRS tailored to Asian males including data from Korea, China, and Japan, and discuss the clinical implications for prediction of early onset and aggressive PCa.

Automatic acquisition of “noun+verb” idiomatic compounds in Korean

송상헌 경희대학교 언어정보연구소 2015 언어연구 Vol.32 No.1

The state-of-the-art skills of computational linguistics pay attention to lexical semantics, because it has a potential to be used to improve language processing systems in terms of coverage as well as accuracy. In particular, utilizing multiword expressions is importantly regarded as one of the components to foster performance of language applications. Handling these expressions is particularly crucial in multilingual processing, such as machine translation. Amongst a variety of multiword expressions, the present study investigates “noun+verb” idiomatic compounds in Korean. These compounds are made up of a verb plus the verb’s syntactic object, and what the combination of the two words conveys is not equivalent to the sum of the meanings of the parts. In order to acquire the “noun+verb” idiomatic compounds in Korean in a fully automatic way, the current work exploits a syntax-annotated corpus (i.e. treebank) and three lexical hierarchies in Korean. The current work extracts the syntactic patterns from the development corpus (the Sejong Korean Treebank), calculates the selectional preferences each verbal item has with its objects, and identifies the idiosyncratic items with reference to the three lexical hierarchies (CoreNet, KorLex, and U-WIN). The result includes 548 idiomatic compounds, 70% of which are evaluated as satisfactory.

VST 및 FPGA를 이용한 전자표적 생성 및 신호 모의장치 개발

송상헌,Sanghun Song 한국군사과학기술학회 2023 한국군사과학기술학회지 Vol.26 No.4

In this paper, the target simulator for RF signals was developed by using VST(Vector Signal Transceiver) and set by real-time signal processing SW programs. A function to process RF signals using FPGA(Field Programmable Gate Array) board was designed. The system functions capable of data processing, raw signals monitoring, target signals(simulated range, velocity) generating and RF environments data analyzing were implemented. And the characteristics of modulated signal were analyzed in RF environment. All function of programs for processing RF signal have options to store signal data and to manage the data. The validity of the signal simulation was confirmed through verification of simulated signal results.

한국어 Wh-요소의 화용적 쓰임

송상헌 고려대학교 언어정보연구소 2010 언어정보 Vol.0 No.11

This paper investigates peculiar usages of Wh-elements in Korean. The usages that this paper covers, which often refer to rhetorical questions, have a property of both interrogatives and quantifiers simultaneously. That means, the Wh-elements function like a trigger to derive the form of interrogative sentences, but they convey quantificational readings. This paper provides several constraints of the peculiar usages of Wh-elements; in particular, the Wh-elements show a tendency to co-occur with some adverbs that express speaker's psychological status. On top of this, this paper also looks into the pragmatically peculiar usage of 'why' in Korean. If the 'why' word in Korean appears in tag questions, it assumes two properties; one is the word itself is optional, the other is the word always co-occur with stative verbs.
