Pied-piping and Preposition Stranding in Terms of Optimality Theory

최동익 한국영어학회 2008 영어학 Vol.8 No.2

Korean Journal of English Language and Linguistics 8-2, 251-264. There are two positions of a wh-word and related preposition in English: so-called pied-piping, occurrence of a wh-word immediately preceded by a preposition at the beginning of a clause, or preposition stranding, occurrence of only a wh-word at the beginning of a clause with a preposition left behind. This is not always the case. Romance languages like French and Italian only allow pied-piping. This paper shows that these differences between languages can be captured well in terms of Optimality Theoretic approach, i.e. the interaction of *Prep stranding which says that a preposition must be a sister to its object and Align which says that the left edge of an interrogative should be aligned with the left edge of CP. The tied ranking of *Prep stranding and Align yields preposition stranding sentences as well as pied-piping ones as optimal in current English. The strict ranking of *Prep stranding >> Align yields pied-piping ones as optimal in case of Romance languages. This result is consistent with the Optimality Theoretic assumption that language variations can be explained in terms of the change in the rank of the constraints.

肝吸蟲代謝産物과 蟲體構成物로 感作한 햄스터에서 免疫의 移入

崔東翊,朴武吉 慶北大學校 醫科大學 1987 慶北醫大誌 Vol.28 No.3

肝吸蟲의 代謝産物과 蟲體構成物로 感作한 近交系 golden 햄스터의 腹腔渗出細胞, 脾臟細胞 및 血淸이 recipient햄스터에 免疫을 移入하는지 究明하였다. Donor 햄스터는 5마리씩 2群으로 나누어 第Ⅰ群에는 0.1㎖의 代謝産物과 Freund's incomplete adjuvant의 同量 混合物을, 第Ⅱ群에는 0.1㎖의 蟲體構成物과 adjuvant의 同量 混合物을 ㄹootpad에 2回 注射한 다음 2週後에 麻醉시켜 腹腔渗出細胞, 脾臟細胞 및 血淸을 採集하여 recipient햄스터의 腹腔內에 注入하였다. Recipient햄스터는 5마리씩 6群으로 나누어 第1群에는 第Ⅰ群 donor 햄스터의 腹腔渗出細胞 5×10 exp (5) 및 血淸 1㎖를, 第2群에는 第Ⅰ群의 脾臟細胞 2×10 exp (6) 및 血淸 1㎖를, 第3群에는 第Ⅱ群 donor 햄스터의 腹腔渗出細胞 5×10 exp (5) 및 血淸 1㎖를, 第4群에는 第Ⅱ群의 脾臟細胞 2×10 exp (6) 및 血淸 1㎖를, 第5群에는 非感作對照햄스터의 腹腔渗出細胞 5×10 exp (5) 및 血淸 1㎖를, 第6群에는 對照햄스터의 脾臟細胞 2×10 exp (6) 및 血淸 1㎖를 各各 腹腔內에 注入하여 第1次 感作하였다. 第1次 感作한 7日後 全햄스터에 肝吸蟲 被襄幼蟲 30마리를 經口 challenge感染시켜 15日부터 EpG의 計算을 하였고 challenge 感染後 50日에 모두 屠殺하여 對照群의 worm burden 및 脾臟當 plaque形成細胞數를 基準으로 하여 이들 細胞와 血淸의 注入으로 recipient햄스터에 免疫이 移入되는지 그 與否를 判定하였다. Challenge 感染後 第1, 第5 및 第6群 햄스터에서는 第15日째, 第2, 第3 및 第4群 햄스터에서는 第16日째에 肝吸蟲卵이 formalin-ether 集卵法으로 나타났으며 Eggs per Gram은 Stoll氏 計算法으로 第16日 및 第17日째부터 나타났고, 단도에서 肝吸蟲의 排出로 推定되는 EpG의 急激한 增加는 感作群인 第1, 第2 및 第4群에서는 第28日째, 第3群에서는 31日째에 나타났는데 比하여 非感作對照群인 第5 및 第6群에서는 40日 또는 43日째에 나타났다. 햄스터 단도내 worm burden은 感作群 햄스터(平均 13.2∼15.0마리)는 非感作對照群 햄스터(平均 18.4∼19.0마리)에 比하여 有意的으로 적었다. 脾臟에서 plaque形成細胞는 非感作對照群에서는 檢出할 수 없었고 感作群인 第1, 第2, 第3 및 第4群 햄스터에서는 少數 檢出할 수 있었다. 이 成績으로 미루어 보아 肝吸蟲의 代謝産物과 蟲體構成物로 感作한 햄스터의 腹腔渗出細胞 및 血淸과 脾臟細胞 및 血淸의 recipient햄스터의 腹腔內注入은 免疫이 移入됨을 나타내었다. This study was undertaken to evaluate the role of peritoneal exudate cells(PEC), spleen cells (SC) and serum in the transfer of immunity against Clonorchis sinensis in the isogenic golden hamsters. The donor hamsters (DH) were divided into two groups. One group was sensitized with twice injections of the admixture of the metabolic products of C. sinensis and Freund's incomplete adjuvant into footpads, and the other group was sensitized with the admixture of somatic constituents and the adjuvant. Two weeks after sensitization, the DH were killed by deep anesthesia and the PEC, SC and serum were collected. Recipient hamsters (RH) were divided into 6 groups. The hamsters of Group Ⅰ were injected intraperitoneally (IP) with 5×10 exp (5) PEC and 1 ㎖ of serum from Group Ⅰ DH, those of Group 2 were injected IP with 2×10 exp (6) SC and 1 ㎖ of serum from Group Ⅰ DH, those of Group 3 were injected IP with 5×10 exp (5) PEC and 1㎖ of serum from Group Ⅱ DH and those of Group 4 were injected IP with 2×10 exp (6) SC and 1 ㎖ of serum from Group Ⅱ DH. The hamsters of Group 5 were injected IP with 5×10 exp (5) PEC and 1 ㎖ of serum and those of Group 6 were adminstered IP with 2×10 exp (6) SC and 1 ㎖ of serum from non-sensitized controls. Seven days after primary sensitization, RH were challenged orally with 30 metacercariae and Eggs per Gram (EpG) of fecal samples were counted from 15 to 49 days after challenge. The RH were killed 50 days after challenge, and the transfer of immunity to the RH was estimated by significances in EpG, mean worm burdens, and plaque forming cells per spleen between sensitized and non-sensitized groups. The eggs of C. sinensis appeared in the 15th day after challenge in Groups 1,5,6 and the 16th day in Groups 2,3,4, by the formalin-ether sedimentation and EpG noted in the 16th and the 17th days by Stoll's egg counting techniques. The sudden increase of EpG, which assumed to be expelled the flukes into the intestinal tract, was encountered in the 28 days in Groups 1,2,4, and the 31st day in Group 3. Whereas, it appeared in the 40th day in Group 5 and the 43rd day in Group 6. The mean numbers of sensitized groups (RH of Groups 1,2,3,4) harbored fewer flukes than the non-sensitized groups and the differences in mean worm burdens were significant by the paired t-test. The plaque forming cells were found in the all sensitized groups, but no plaque forming cell was encountered in the nonsensitized groups. It is likely that the intraperitoneal injection of peritoneal exudate cells and serum or spleen cells and serum from the donor hamsters sensitized with the metabolic products and somatic constituents of C. sinensis caused the transfer of immunity to the recipient hamsters.

崔東翊,具玄謨 慶北大學校 醫科大學 1988 慶北醫大誌 Vol.29 No.1

1987年 6月부터 同年 9月까지 慶北 琴湖江流域 上流인 永川에서 投網 및 사발모지等으로 淡水魚를 採集하여 肝吸蟲 被囊幼蟲의 寄生率과 寄生程度를 調査하였고, 그 成績을 西村(1943), Choi(1976), 朴(1978), Hwang 및 Choi(1980)의 成績과 比較하였다. 採集된 淡水魚 12種 중 8種, 즉 참붕어(P. parva), 큰납지리(A. taenianalis), 칼납자루(A. limbata), 몰개(G. atromaculatus), 동사리(O. obscura), 납지리(P. rhombea), 모래모치(P. esocinus) 및 돌고기(P. herzi)等에서 肝吸蟲 被囊幼蟲을 찾아볼 수 있었으며, 그 寄生率은 참붕어(P. parva), 모래모치(P. esocinus) 및 돌고기(P. herzi)에서는 모두 100%였고, 이어서 칼납자루(A. limbata) 65.7%, 납지리(P. rhombea) 61.0%, 몰개(G. atromaculatus) 52.8%, 동사리(O. obscura) 45.5%, 큰납지리(A. taenianalis) 41.4%의 順位로 낮았다. 寄生程度의 標識로서 魚肉 1g當 肝吸蟲 被囊幼蟲의 平均數는 참붕어(P. parva) 87.5個로서 가장 많았고 큰납지리(A. taenianalis)에서 0.7個로 가장 적었으며, 칼납자루(A. limbata), 몰개(G. atromaculatus), 동사리(O. obscura), 납지리(P. rhombea), 모래모치(P. esocinus) 및 돌고기(P. herzi)는 2.7∼33.3個로서 中間値를 나타내었다. 肝吸蟲 被囊幼蟲의 寄生率은 以前의 調査成績보다 大體로 높았으나 그 寄生程度는 魚種別로 若干의 變動을 나타내었다. From June to September, 1987, fresh-water fish were collected by throwing a cast net and using glass bowl containing crushed oil-cake as bait at Yongcheon area in the upper stream of river Kumho, Kyungpook Province, Korea. The infestation pattern of Clonorchis sinensis mesacercaria from the fish was determined and compared with the results reported by Nishimura(1943), Choi(1976), Park(1978) and Hwang and Choi(1980). Twelve kinds of fresh-water fish were collected in the river of Yongcheon, of which, eight kinds of fish, Acanthorhodeus taenianalis, Acheilognathus limbata, Gnathopogon atromaculatus, Odontobutis obscura, Paracheilognathus rhombea, Pseudogobio esocinus, Pseudorasbora parva and Pungtungia herzi were infested with the metacercaria of C. sinensis. The infestation rate for the metacercaria was the highest in P. esocinus, P. parva and P. herzi 100% ; followed by A. limbata 65.7%, P. rhombea 61.0%, G. atromaculatus 52.8%, O. obscura 45.5% and A. taenianalis 41.4%, in decreasing order. In the intensity of infestation with the metacercaria, P. parva was the most heavily infested and the average number of metacercariae per gram of the flesh was 87.5, A. limbata, G. atromaculatus, O. obscura, P. rhombea, P. esocinus and P. herzi were infested intermediately with from 2.7 to 33.3. Whereas, A. taenianalis was infested with the least number 0.7. It was found that the infestation rate for the metacercaria was higher than the results reported by former investigators, however, there was some fluctuation in the intensity of infestation with the cysts.

南大川 淡水魚에 寄生하는 吸蟲類 被囊幼蟲

崔東翊,鄭惠永 慶北大學校 醫科大學 1986 慶北醫大誌 Vol.27 No.1

1984年 3月부터 同年 9月까지 慶北 蔚珍郡 平海面 南大川에서 淡水魚를 採集하여 吸蟲類 被襄幼蟲의 寄生狀을 調査하였다. 南大川에서 採集한 魚種은 붕어, 꼬치동자개, 꺽지, 몰개, 버들치 및 갈겨니의 6種이었고 吸蟲類 被襄幼蟲이 寄生되어 있는 魚種은 몰개와 갈겨니의 2種이었다. 몰개에는 4種의 吸蟲類 被襄幼蟲, 肝吸蟲, Cyathocotyle orientalis 幼蟲, Exorchis oviformis 幼蟲, Echinochasmus 屬幼蟲과 1種의 所屬未定 被襄幼蟲이 寄生되어 있었고 갈겨니에는 Exorchis oviformis 幼蟲 1種이 寄生되어 있다. 몰개에서 肝吸蟲 被襄幼蟲의 寄生率은 13.0% 였고 그 寄生程度는 魚肉 1 gram 當 6個로써 낮았다. 나머지 吸蟲類 被襄幼蟲의 寄生率과 寄生程度는 모두 낮았다. From March to September, 1984, fresh-water fish caught in the river Namdae, Pyonghae myun Uljin county in Kyungpook Province were examined for the presence of larval trematodes. Six species of fish, Carassius carassius, Coreobagrus brevicorpus, Coreoperca herzi, Gnothopogon atromacultatus, Moroco oxycephalus and Zacco termincki were collected in the river. Of these, only two species of fish harbored larval trematodes. G. atromaculatus harbored four kinds of larval trematodes, Clonorchis sinensis, Cyathocotyle orientalis, Exorchis oviformis, Echinochasmus species, and a kind of undetermined larva. However, Z. termincki had only one kind of larva, E. oviformis. The infestration rate for C. sinensis metacercaria in G. atromaculatus was 13.0 per cent and its intensity was relatively low, 6 per gram of flesh. The rate and intensity of infestation of the other larval trematodes were generally low.
