A Note on Numerical Approaches for Heat-Diffusion Equation with Heterogeneous Media and Its Applications

서샛별 영남수학회 2019 East Asian mathematical journal Vol.35 No.1

In this paper, we introduce a numerical approach to solve heat-diffusion equation with discontinuous diffusion coefficients in the three dimensional rectangular domain. First, we study the support operator method and suggest a new method, the continuous velocity method. Fur- ther, we apply both methods to a diffusion process for neurotransmitter release in an individual synapse and compare their results.

Agreement of a Point-of-Viewer and a Jussive Subject

서샛별,허세문 한국생성문법학회 2015 생성문법연구 Vol.25 No.1

This paper investigates the person feature restrictions on Jussive subjects. First, we present three cases of Jussive constructions: Typical-Jussives, Indirect Order, and Non-Typical Exhortatives. Traditionally, previous works in the literature have been concerned with the former two, where a Jussive subject and a Jussive head are totally identical or completely different from each other. However, we introduce a new case, Non-Typical Exhortatives, in which person features of an Exhortativeparticle are partially manifested by a Jussive subject. We try to proposea unified approach using Agree, based on the recent influential analysisof Zanuttini, Pak, and Portner (2012, NLLT), but show that a simpleAgree analysis brings about an under-generation problem. We then demonstrate that information of a Jussive head is passed on to a Jussivesubject via a Point-of-Viewer (POV) feature which is related to aconversational participant. Additionally, we propose that first andsecond person POV features on an Exhortative head can behave individually when they participate in Agreeing with a Jussive subject:subset probing. With this, the three constructions converge into two maingroups again: Agree vs. Non-Agree. Our proposal suggests that Obligatory Control in embedded Jussives is not derived by Agree. Additionally, it gives an explanation for a wide variety of Exhortative meanings.

NP-ellipsis Revisited: The Role of D-feature

서샛별,고희정 한국생성문법학회 2012 생성문법연구 Vol.22 No.4

This paper investigates the characteristics of NP-ellipsis that co-occurs with a non-nominal category (e.g. CP, NumP) in Japanese and Chinese. First, we show that the recent influential approach to NP-ellipsis by Saito, Lin, and Murasugi (2008, Journal of East Asian Linguistics) bears some inadequacy in explaining the contrast between Japanese and Chinese. We then demonstrate that clausal arguments in Japanese and Chinese behave differently in other domains as well, such as factive constructions and clausal subject constructions. We propose that these facts are correlated with each other, and that the key to understanding the cross-linguistic variation in NP-ellipsis is the role of D-feature. In particular, we argue that NP-ellipsis occurs only when a neighboring phrase contains a D-feature, which can be agreed with a higher D head. Crucially, languages may differ whether a non-nominal category may contain a D-feature or not. We claim that Japanese non-nominal categories such as CPs and NumPs do not carry a D-feature so that NP-ellipsis cannot be licensed regardless of its argument status, in contrast to Chinese counterparts. Our proposal has a theoretical implication that general scrambling and DP-internal movement have different sources - only the latter involves D-feature agreement.

한국어 보편 의존 관계 분석에 관한 제언

서샛별,김명주,성연숙,유성희 한국언어정보학회 2019 언어와 정보 Vol.23 No.1

This paper suggests annotation guidelines to build a Universal Dependencies (UD) treebank for Korean. We discuss the part-of-speech annotation of Korean specific-categories such as prenouns, numeral classifiers, and (pre)final endings, and propose how to implement UD scheme in Korean regarding selecting a head and assigning dependency relations to dependents. UD prioritizes content words over functional words since the former exhibits less cross-linguistic variations. In a noun phrase, for instance, a core noun is always a head of the entire noun phrase independently of a language. The rest are treated as a dependent: not only a modifier such as an adjective but also a functional category such as an article, numeral quantifier, demonstrative, and so on. However, when it comes to head-less constructions such as coordination or predicate ellipsis, UD firmly advocates the head-initial strategy. The present application of UD to Korean tries to follow UD’s principles as much as possible. Korean is a head-final language, so that headed constructions are analyzed head-finally. In contrast, head-less ones are tagged head-initially. This might disregard language-specific characteristics from a linguistic perspective, but the strategy allows us to build up a set of treebanks in a cross-linguistically consistent way (i.e., the fundamental purpose of UD).

박근혜 정부의 치안정책 및 범죄추세 분석에 관한 연구

김창윤 ( Kim Chang Yun ),서샛별 ( Seo Sat Byul ) 한국경찰학회 2018 한국경찰학회보 Vol.20 No.6

박근혜 대통령의 시대적 임무에 대한 인식을 총체적으로 보여주는 표현은 ‘국민행복시대의 완성’이라고 볼 수 있다. 이를 위해 세부적으로 안전, 경제부흥, 복지국가, 경제민주화 등을 추구했다. 박근혜 정부의 경찰관련 중요 국가정책으로 ① 성폭력, ② 가정폭력, ③ 학교폭력, ④ 불량식품 등과 같은 4대 사회악 근절이었다. 이에 따른 경찰의 치안정책으로 ‘여성청소년수사팀 확대 정책’, ‘성폭력분야 전담수사체계 정책’, ‘불량식품 단속을 위한 액센트 단속 정책’등을 추진하였다. 박근혜 정부의 범죄추세를 민주화 시대 이후 역대정부와 비교한 결과는 다음과 같다. 민주화 시대가 개막된 이후의 총범죄 증가율은 김영삼 정부는 17.8% 증가, 김대중 정부 7.1% 증가, 노무현 정부 3.1% 감소, 이명박 정부 1.0%가 감소, 박근혜 정부 0.42% 감소하였다. 총범죄율은 이승만 정부부터 김대중 정부까지는 지속적으로 증가하였다. 노무현 정부와 이명박 정부부터 증가세가 감소되었으며, 이러한 추세는 박근혜 정부에서도 이어졌다. 인구10만 명당 범죄발생율은 김영삼 정부 5.7% 증가, 김대중 정부 17.6% 증가, 노무현 정부 7.9% 감소, 이명박 정부 5.6% 감소, 박근혜 정부 3.27% 감소로 나타났다. 경찰관 수의 변화에 있어서 김영삼 정부의 경찰관수는 처음으로 3%가 감소하였다. 김대중 정부 경찰관수는 1.33% 증가, 노무현 정부 경찰관수는 4.7% 증가, 이명박 정부의 경찰관수는 4.9%가 증가, 박근혜 정부의 경찰관수는 8.83%로 가장 큰 폭으로 증가하였다. This Study considers the Police Policy and Crime Trends in South Korea from 2013-2017. The data that we has analyzed for was obtained from official crime statistics, “Analytical Report on Crime,” which was published by the Korean Police. We analyzed Park Guen-hye presidential term from 2013 to 2017. The slogan of Park Geun-hye administration as a whole showing the perception of the duty of the times can be seen as the completion of the era of National Happiness. To this end, Park Geun-hye government pursued safety, economic revival, welfare state and economic democratization in detail. The most important national policies related to the police of Park Geun-hye administration were ① sexual violence, ② domestic violence, ③ school violence, and ④ defective food. As a result, the police policy in this term had been promoted as the expansion of the female juvenile investigation team, the policy of dedicated investigative system in the field of sexual violence, and the policy of controlling accidents for cracking down on defective food. The results of the comparison of the crime trends in Park Geun-hye term with the previous government since the era of democratization are as follows. Since the beginning of the democratization era, the rate of total crime has increased by 17.8%, Kim Dae Jung government increased by 7.1%, Roh Moo Hyun government has decreased by 3.1%, Lee Myung Bak government has decreased by 1.0% and Park Geun Hye government has decreased by 0.42%. The total crime rate continuously increased from the Rhee government to the Kim Dae-jung administration. The growth rate has decreased since the Roh Moo-hyun administration and the Lee Myung-bak administration, and this trend has continued in the government. The incidence of crime per 100,000 population increased by 5.7% in the Kim Young-sam government, 17.6% in the Kim Dae-jung government, 7.9% in the Roh Moo-hyun government, 5.6% in the Lee Myung-bak government and 3.27% in the government. The number of police officers in the Kim Young-sam government decreased by 3% for the first time in changing the number of police officers. The number of government police officers in Kim Dae-jung increased by 1.33 percent, the number of police officers in Roh Moo-hyun increased by 4.7 percent, the number of police officers in the Lee Myung-bak government increased by 4.9 percent, and the number of police officers in Park Geun - Hye increased by 8.83 percent.

중학생의 자기인식, 학업적 자기효능감이 학교적응과 학업성취도에 미치는 종단적 영향 연구

김진희(Kim jinhee),서샛별(Seo satbyul) 학습자중심교과교육학회 2020 학습자중심교과교육연구 Vol.20 No.10

본 연구에서는 중학생의 자기인식, 학업적 자기효능감, 학교적응과 학업성취도의 종단적인 관계를 살펴보기 위하여 경기교육종단연구 중학생 패널 4차년도(2014년), 5차년도(2015년), 6차년도(2017년) 데이터를 사용하여 다변량 잠재성장모형 분석을 실시하였다. 분석 결과를 종합하면 다음과 같다. 첫째, 중학생들은 학년이 올라갈수록 자기인식은 증가하다가 감소하였고, 학업적 자기효능감과 학교적응은 감소하였으며, 학업성취도는 증가하는 것으로 나타났다. 둘째, 자기인식, 학업적 자기효능감, 학교적응과 학업성취도의 종단 관계를 분석한 결과 세 변인의 초기치는 학업성취의 초기치와 변화율을 정적으로 예측한 반면, 세 변인의 변화율은 학업성취도의 변화율을 부적으로 예측하였다. 셋째, 세 변인의 변화율이 학업성취도 변화율에 미친 영향력을 분석해 보면, 학업성취도에 영향력이 큰 변수는 순서대로 학업적 자기효능감, 자기인식, 학교적응 순으로 나타났다. 이와 같은 결과를 바탕으로 중학교 교육에 대한 시사점을 논의하였다. This study is to examine the longitudinal relationship among self-recognition, academic self-efficacy, school adjustment, and academic achievement of the middle school students. We constructed a multivariate latent growth model analysis using the three years sequential data of middle school students(2015-2017). The results of this study were as follows. First, middle school students showed that self-recognition increased and decreased as they go up in grade, while academic self-efficacy and school adjustment decreased, and academic achievement increased. Second, the longitudinal relationships of self-recognition, academic self-efficacy, school adjustment with the academic achievement were as following. The initial values of the three variables are positively correlated with the initial value and the rate of change of academic achievement, while the rate of change of the three variables had negative correlation with the rate of change in academic achievement. Third, we analyzed the influence of the rate of change of three variables on the rate of change in academic achievement. The variables with the greatest influence on academic achievement were in order of academic self-efficacy, self-recognition, and school adjustment. Based on these results, we discussed implications for middle school education.

Korean Internally-Headed Relatives and Their Potentially Homophonous Constructions

Sang-Hee Park(박상희),Saetbyol Seo(서샛별),Semoon Hoe(허세문) 한국언어학회 2020 언어 Vol.45 No.1

It is commonly acknowledged that Japanese internally headed relatives are homophonous with several other distinct constructions. This homophony has been the source of disagreement among researchers on the relevant data. In particular, Grosu & Hoshi (2019) argue that prima facie internally headed relatives with a referential head really are doubly headed relatives, but Kitagawa (2019) suggests that they are bona fide internally headed relatives. In this squib, we provide an initial assessment of the relevant data in Korean. Our data show that Korean internally headed relatives coexist with other possibly homophonous constructions that hitherto have rarely been discussed. Because doubly headed relatives are of questionable status in Korean, Grosu & Hoshi’s assumption that referential nominals are not appropriate as the internal head does not seem to hold. The findings of this squib, though tentative, raise intriguing questions concerning empirical facts about internally headed relatives of the Japanese/Korean kind and shed light on previous cross-linguistic assumptions on head-internal relatives.
