A snake model, proposed by Kass et al., may yield different forms of image contours depending on an energy functional being minimized and a minimization procedure used. This paper addresses the problem of minimizing the energy functional so that a resulting snake may represent desired image contours. We show that good results can be obtained by shaking a search area over which an energy functional is to be minimized.

서술관계(predication)에 의한 영어의 관계구분에 대한 분석

양윤국 상명대학교 논문집 1986 상명대학교논문집 Vol.18 No.-

This paper aims to describe the relationship between English relative clauses and their heads through the predication theory proposed by Rothstein (1985). It also attempts to discuss analyses of the internal structure of relative clauses. He has proposed a more developed predication theory than that of Chomsky or Williams in syntactic terms. He claimed that all the non-argument XP should be linked to an argument X which is theta-marked by Predicate-Linking Rule. In chapter Ⅱ, we have shown that this Predicate-Linking Rule plus a great role in judging whether a certain structure is well-formed or not. In chapter Ⅲ, the relationship between relative clauses and their Head has been discussed, based on the Predicate-Linking Rule. In general, the relative clauses are non-theta-marked XP. Therefore, these XP (= maximal projection) should be linked to their head, which is theta-marked argument, so that they could be well-formed. The relative clause with a relative pronoun 'what', on the other hand, is theta-marked argument XP, not being linked to any argument. This accounts for why such relative clauses do not take any lexical item as their head. In chapter Ⅳ, we have reviewed analyses which many linguists have made on the internal structure of relative clauses. These analyses are classyfied into three types. The first analysis is made on the assumption that relative pronouns are moved into COMP by Move-α in the relative clauses in which relative pronouns occur and in the clauses in which the relative pronouns are deleted, deletion rule should be applied before Move-α. The second analysis is made on the assumption that the relative pronoun-deleted clause is derived through the application of deletion rule in the base-structures. The third type of analysis is made, assuming that the relative pronouns in COMP and traces are both generated at the base-structures. All things considered, we have claimed that the second type of analysis is more valid, being able to make cosistent description of the internal structure of English relative clauses.

Pro-VP form 'do so'의 통사적 제약에 관해서

梁倫國 상명대학교 논문집 1984 상명대학교논문집 Vol.14 No.-

This paper aims to review the previous analyses on the syntactic behaviors of pro-VP form "do so", proposing an alternative to the previous approaches, based on the Binding Theory of Chomsky's GB model. In sections (Ⅰ) and (Ⅱ), we reviewed approaches attempted by generative semanticists and interpretive semancicists. The former claimed that pro-VP do so should be inserted by Do-Gobbling and So-Insertion transformations. The latter, on the other hand, assumed that pro-VP forms should be base-generated and accordingly, their antecedents in the linguistic contexts should be determined by interpretive rules and at least sometimes they need not have their antecedents in the contexts. In sections (Ⅲ)···(Ⅴ) we discussed the weaknesses of the interpretive semanticists' views, proposing that the concept of syntactically controlled anaphors be revised. We have presented revised definition of anaphors: 1. Overt-structurally bound anaphors (=pro-VP do) 2. overt-or covert-structurally bound anaphors (=pro-VP do so) 3. pragmatically bound anaphors (= pro-VP do it), which is the same as that of interpretive semanticists'. In section (Ⅵ) we have discussed the syntactic behaviors of do so in connection with Binding Theory of GB model. As a result we have reached conclusion that GB's Binding Theory should be extended to the domain of discourse beyond the sentence level, to explain the linguistic behaviors of pro-VP forms, including do so. Therefore we have preposed the discourse Binding Theory as follows: 1. pro-VP do is overt-structurally bound by its antecendent VP somewhere in the discouse. 2. pro-VP do so is overt-structurally or covert-structurally bound by its antecedent VP somewhere in the discourse. 3. pro-VP do it need not be either overt-strucrually or covert-structurally bound by its antecedent VP somewhere in the discourse, i.e. is pragmatically bound. Finally in section (Ⅶ) we briefly discussed the generality as well as the validity of our proposal.

자질점검과 재귀대명사의 분포

This paper aims to briefly review grammatical descriptions of distributions of English Reflexive Pronouns in the Standard Theory based a system of rules, in the Government and Binding Theory founded on Principles and Parameters, and attempts to describe their distributions via checking theory based on Agree system under the Minimalist Program. Our attempt reveals that checking theory based on Agree system has some problems in accounting for their distributions and that some additional assumptions should be required. As an alternative to such problems raised in the analyses via checking theory based on Agree system we make the following assumptions: a. Functional category, T inherently carries Nominative Case; functional category, ν, inherently Accusative Case when they are selected from the lexicon and into Numeration, forming a lexical array. b. Reflexive Pronouns inherently carry Accusative Case when they are selected from the lexicon and into Numeration, forming a lexical array.

Precision-TPA를 이용한 구치부 회전시 근심 및 원심삽입법에 따른 동적인 치아이동 양상에 관한 실험 연구

양성재,정성권,노준,전윤식 대한치과교정학회 1999 대한치과교정학회지 Vol.29 No.4

회전된 구치를 개선시키기 위해 사용하는 precision-TPA(transpalatal arch)를 삽입방법들-근심삽입법, 원심삽입법, 확장력을 부여한 근심삽입법 (이하 근심확장법) -에 따라 동적인 치아이동의 양상과 치열궁의 변화를 비교하기 위해 본교실에서 개발, 제작한 Calorific machine을 이용하여 실험한 후 회전된 치아와 고정치간의 이동양상을 계측하여 통계처리한 결과 다음과 같은 결론을 얻었다. 1. 구치간 폭경은 근심삽입법에 의해 감소하였고, 원심삽입법과 근심확장법에 의해서는 증가하였다. 2. 원심삽입법에 의해서 치열궁 장경이 가장 증가하였고, 근심확장법, 근심삽입법순으로 증가하였다. 3. 근심삽입법의 회전중심은 근심소와(mesial pit)와 중심소와(central pit)사이에위치하였고, 원심삽입법에서는 원심소와(distal pit)와 원심설측교두 (distolingual cusp)사이에, 근심확장법은 원심소와(distal pit)에 위치하였다. Dr. Youn-Sic Chun and coworkers invented the new machine for getting information about the relative effectiveness of the orthodontic appliances and we named it Calorific machine. The author and colleagues used this machine to compare with tooth moving mechanism by 3 types of the insertion method of precision-TPA for derotating the posterior teeth. We measured the distance of tooth movement and found out the rotational center on the occlusal X-ray film and the tooth movement on the occlusogram and then processed paired t-test by SAS program. The results were as follows : 1. In the intermolar width, the mesial insertion method showed the loss of distance, and the other methods (-distal insertion method, mesial expansion method-) showed the increase of distance. 2. In the arch length, the distal insertion method was exhibited as most recommandable way for increasing the arch length. 3. The rotation center of the mesial insertion method for derotating the molar, was located between mesial pit and central pit of the lower 2nd molar. And, in the distal insertion method, it was located between distal pit and distolingual cusp. and in the mesial expansion method was located at distal pit.

저자들은 척수압박으로 하지마비를 보인 환자에서 수술 후에 급성 백혈병에 동반된 과립구성 육종으로 진단된 환자 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Granulocytic sarcoma(GS) is an uncommon tumor composed of immature cells of the granulocytic series. Most case of GS occur in the course of acute leukemia and the blast crisis of chronic leukemia, Rarely, however, it may present before leukemia becomes clinically apparent. It may also occur in patients with myeloproliferative disoders. GS has been reported that it occurs in 3% to 9% of patients with acute myelogenous leukemia(AML) and the incidence of GS is reported to be higher in patients with t(8;21). GS occurs relatively commonly in africa and has been reported to affect 10-25% of black children presenting with AML. This is very rare case of granulocytic sarcoma with AML(FAB M5) presented with spinal cord compression which was supported by decompression laminectomy.

최소주의 이론의 최근 경향

양윤국 상명대학교 인문과학연구소 2002 人文科學硏究 Vol.11 No.-

본 논문은 Chomsky(2000, 2001)를 중심으로 최소주의이론의 최근 흐름을 검토하여 이들의 이론적 장, 단점과 그에 대한 대안을 논의하고 제시하는 데 목적이 있다. 우선 최근의 수정, 보완된 최소주의 이론의 이론적 우월성은, 자질점검을 범주나 자질의 이동이 없이 탐색자질과 연결자질이 연결관계만 성립하면 삭제되는 것으로 가정함으로서 과거의 점검영역을 문법에서 제거했으며, 따라서 자질점검을 위해서는 반드시 거쳐야하는 유인(또는 이동)의 과정을 없앴으며, 또한 허사 here구문의 분석에서 there의 관련명사구가 자질점검 즉 격자질 점검을 받기 위해 there에 결속되도록 하기 위해서 논리접사로 규정해야만 하는 등 일반성이 없는 설명(account)이 없어져. 경제성 원리의 견지에서 설명력이 제고된 것으로 보인다. 반면, 제 5 장에서 논의된 문제를 해결하기 위해서는, 보충어로 선택되는 범주의 유형에 따라 그 보충어를 선택하는 동사의 선택자가 υ 또는 T로 구분해야 한다. 같은 타동사이지만 CP(통제 T구문 포함)를 취하는 동사의 경우는 그의 선택자가 T가, 비통제 구문을 취하는 동사의 경우는 그의 선택자가 υ가 되어야 제 5 장에서 제기되었던 문제를 해결할 수 있다고 생각된다.

Concrete is one of the principal materials for the structures and It is widely used all over the world While advanced technologies of concrete have been recently focused especially on developing high performance concrete In which possess high compressive strength and durability, such concrete shows extremely brittle failure under shear and tension To Improve such a poor properties, high performance fiber reinforced cement composites(HPFRCC) has been developed For forming multicrack, a large number of fiber and/or the high specific area with thinner fibers are required However, It causes difficulties for the extrusion because of the poor workability So, this theses was suggested adequate mixing method and mix proportion for cach fibers and experimentally observed Structural performance of the seismic devices made by steel bar and HPFRCC These dampers will be applied for reducing damage as weil as seismic response The advantages of the HPFRCC damper is selective structural performance, strength, stiffness, and ductility by changing configuration, bar arrangements and type of materials used The experimental results indicate that elemental ductility is much increased with decreasing damage when the HPFRCC are applied to the damper It means cementitious seismic damper for structure control is available, which has much merit in performance and cost
