The Unstressable Word Syndrome in 2-Syllable Words

조혜성 대한언어학회 2014 언어학 Vol.22 No.4

The goal of this paper is to examine the unstressable word syndrome in 2-syllable words with final extrametricality within Optimality Theory (OT). The way a language selects its repair strategies depends on both the avoidance of final stress and its possible minimal word size. In order to account for the generalization with respect to repair strategies such as lengthening/gemination, incorporation, and revocation of extrametricality, we propose a repair-specific NONFINALITY(σweak-in-foot) constraint as a replacement of NONFINALITY(FT) constraint. The observation that the domain of repairs is 2-syllable words straightforwardly leads to our argument against the traditional application of NONFINALITY(FT) to them since it assumes its maximal domain is more than 2-syllable words in size when words are only light syllables. With the NONFINALITY(σweak-in-foot) constraint we can account for the disyllable-specific unstressable word syndrome in a consistent and coherent way which previous OT accounts cannot. Furthermore, different ranking relations established among NONFINALITY(), NONFINALITY(σweak-in-foot) and PARSE-SYL provide a typological prediction for all repair strategies.

Role of Prostaglandin E in Modulating Immune Response in Lymph Nodes Draining the Uterus during the Implantation Period in Rats

본 교실의 연구결과에 의하면 토끼와 흰쥐에서 수정란 착상시기에 peripheral lymphocyte와 thymocyte의 활성도가 저하될 뿐만 아니라 착상기간중 생성되는 prostaglandin E(PGE)의 생리적인 농도로도 peripheral lymphocyte와 thymocyte의 활성도가 억제되었다. 그러므로 본 연구에서는 흰쥐의 착상시기에 전신적인 면역기능 뿐만 아니라 국소적으로 DLN lymphocyte의 활성도가 억제되는지를 관찰하고 PGE가 어떠한 기전으로 모체의 면역기능을 억제하는가를 관찰하여 다음과 같은 결과를 얻었다. 1. 흰쥐의 착상시기에 DLN lymphocyte의 활성도가 임신하기 않은 흰쥐의 DLN lymphocyte에 비하여 통계적으로 유의하지는 않으나 저하되었으며 이러한 저하현상은 100% 흰쥐에서 관찰되었다. 2. 착상시기의 DLN lymphocyte에 prostaglandin 합성억제제인 indomethacin(ID)를 처리하면 DLN lymphocyte의 활성도가 통계적으로 유의하게 증가하였다. 그러나 임신하지 않은 흰쥐의 DLN lymphocyte의 활성도는 증가되어 있으나 $PGE_2$를 전처리하면 DLN lymphocyte의 활성도가 유의하게 억제되며 $PGE_2$를 전처치한 후 ID를 처리하면 DLN lymphocyte의 활성도가 $PGE_2$로 전처치하지 않고 ID를 처리한 경우에 비하여 유의하게 증가하였다. 그러나 $PGE_2$ 대신estradiol, progesterone 및 hCG를 전처치하였을 경우에는 ID 처리로 DLN lymphocyte의 활성도가 증가하지 않았다. 3. 임신하지 많은 흰쥐의 DLN lymphocyte에 $PGE_2$를 전처리하면 PGE-producing cell이 유도되어 PGE 생성이 증가하는지를 확인하기 위하여 $PGE_2$를 전처리하고 Con A를 처리한 후 배양액의 PGE를 정량한 결과 PGE를 전처리하지 않은 DLN lymphocyte에 비하여 유의하게 PGE 생성이 증가하였다. 이상의 결과로 보아 흰쥐의 착상시기에는 모체의 DLN lymphocyte의 활성도가 저하되며, 특히 PCE는 PGE-producing cell을 유도함으로써 착상시기의 모체의 면역기능에 영향을 주는 것으로 생각된다. In our previous studies, it was found that activities of maternal peripheral lymphocytes and thymocytes were depressed during the implantation period in rats and rabbits. This study was therefore attempted to clarify further this immunosuppression locally by determining lymphocyte response in lymph nodes draining the uterus (DLN) and to elucidate the mechanism by which prostaglandin E (PGE) modulates immune response during the implantation process in rats. As compared with non-pregnant rats, the response of DLN lymphocytes to concanavalin A (Con A) was depressed during the implantation period in 100% of rats studied. The activity of DLN lymphocytes depressed on day 8 of pregnancy was, however, restored partially by the treatment of indomethacin (ID), indicating that prostaglandin (PG) might be one of factors responsible for immunomodulation during the process of implantation. DLN lymphocyte activity in non-pregnant rats was suppressed if PGE was pre-treated prior to Con A and this suppression was partially restored by the treatment of ID. Furthermore, DLN lymphocytes pre-treated with PGE produced PGE in vitro and this PGE production was blocked by the treatment of ID, suggesting that PGE induced PGE-producing cells. However, the pretreatment of estradiol, progesterone, and hCG at doses enough to suppress lymphocyte activity was ineffective in inducing PGE-producing cells. From these results, it is suggested that PGE induces PGE-producing suppressor cells, thereby increasing PGE concentration and PGE in turn depresses maternal local immune response as well as systemic immune response during the implantation period in rats.

사람의 간암 세포주에서 p53 유전자의 기능과 p21^(CIP1) 유전자 발현의 상관관계에 관한 연구

조혜성,임인경 아주대학교 의과학연구소 1996 아주의학 Vol.1 No.1

Expression of p21^(CIP1) gene has been known to be regulated by p53. We have examined whether basal expression of p21^(CIP1) is directly correlated to the status of p53 gene expression in seven human hepatoma cell lines. Six hepatoma cell lines except Hep3B expressed significant amount of p53 and Rb transcripts. However, only three of the six cell lines(HepG2, SK-HEP-1, HT-17) showed detectable basal expression of p21^(CIP1) transcripts, whereas three other Hub cell lines(Huhl, 4 and 7) originated from Japan did not. Neither p21^(CIP1) nor p53 transcripts were observed in the Hep3B cell line. There, was a considerable correlation between the status of functional p53 and p21^(CIP1) gene expression in these hepatoma cells, since loss of p21^(CIP1) gene expression was observed in the Huh7 cells which have mutated p53 and in the Huhl and Huh4 cells which have HBV containing HBX gene. Treatment of HepG2 hepatoma cells with 25 nM testosterone resulted in higher mitogenic activities by the ³H-thymidine incorporation assay. However, expression of p21^(CIP1) gene did not seem to be involved in mitogenic enhancement by testosterone in these cells.

영어의 /r/의 재고

조혜성 木浦海洋大學校 2001 論文集 Vol.9 No.1

The standard theories assume that English /r/ is classified as one of true consonants which has the feature [+cons]. On the contrary, Kahn(1976) argues that /r/ belong to the glides whose distinctive features are [-cons, +son]. This paper contends that Kahn's classification of /r/ as a glide is right, based on the fact that /r/ behaves differently from other liquids with respect to stress-related processes in English. In that case, it is straightforwardly accounted for that /r/ can bear stress as a nucleus of a syllable since it is sonorous enough to be a syllabic head while other less sonorous liquids like /n, l/ cannot.
