유한요소기법을 이용하여 유동해석의 수치모델을 행하였다 공간을 이산화 할 때에는 Galerkin법을 적용하였으며, 시간의 함수를 이산화 할 때에는 많은 수의 요소와 비정상상태의 문제를 다루는데 있어 장점을 가진 2단계 양해법을 이용하였다. 이동경계조건을 고려한 2차원유통모델을 개발하였고, 직사자형 수조에서 개발된 유동모델을 적용하여 검증하였고, 유용성을 확인하였다. 제주항에 개발된 이동경계기법을 적용하여 계산한 결과, 본 이동경계기법의 좋은 적용성을 보여주었다. 본 연구로부터 이동경계처리 방법이 실해역에서의 유동해석에 있어 유용하고 효율적인 방법이라고 결론지을 수 있다.

In this paper, I argue that the surface constructions for change of state of abstract concepts such as price, mental state, state of life, and possession, passage of time, exchange of idea, etc. are patterned like a motion by means of spatial metaphor; and that English is a co-event language type, so the spatial metaphor is often realized by particles such as `up` and `down` expressing Path in a motion event and by contrast, Korean is a Path language type, so the spatial metaphor is exclusively expressed by means of motion verbs. I also argue that fictive motion such as mental or visual motion results from the metaphorical, subjective conceptualization of the coextensive phenomena such as scenery, roads, etc.

Chomsky (2000) proposes that the operation Attract-F of Chomsky (1995) be replaced by the operation Agree, in which there is, in principle, no movement at all. In the Agree theory, agreement between a Probe P and its Goal G can lead to feature checking in situ. Lasnik (2002), however, argues that feature movement (or attract) is to be preferred to agreement at a distance, presenting three pieces of evidence: pseudo-gapping, sluicing, and remnant movement. The purpose of this article is to show that the agreement-at-a-distance theory of Chomsky (2000) can still be maintained if we adopt Pesetsky and Torrego`s (2001) conception of the EPP property as a "subfeature of a feature." Furthermore, if we assume Boeckx and Stjepanovic´`s (2001) claim that head movement is a PF phenomenon, the persuasiveness of Lasnik`s (2002) argument becomes even weaker. Following Chomsky`s (2001b) assumption that internal Merge can apply either before or after Spell-Out, I have demonstrated that even the remnant movement phenomenon, the most powerful piece of evidence for Lasnik`s (2002) argument, can naturally be accounted for with the feature checking in situ of the Agree theory.

To investigate air quality away from the coastal urban source region, we used a hybrid Eulerian-Lagrangian method which can describe the formation, transport, transformation and deposition processes in complex terrain. with inclusion of shipping sources that were considered to be important emission in the coastal urban region. The result of the Eulerian advection - diffusion prediction was quite similar to that of the Lagrangian particle diffusion prediction. It showed that pollutants emitted from piers can affect the part of inland, especially Dongrae and the coastal area. Those emitted from Sasang and Janglim industrial complexes can affect Hwamyeong and the coastal, respectively. During the daytime the concentration was low due to large deposition flux and terrain effect.

Youngjun Jang. 2001. Complementizers and Complementation in English and Korean: Successive Cyclic WH-Movement. Studies in Modern Grammar 25, 1-28. This paper investigates complementizers and complementation in English and Korean. I argue that a sentence is ultimately a projection of C because the clausal types must be present for interpretation and that the clausal typing feature in C must be checked off. It is shown that the superficial difference between English-type languages and Korean-type languages with regard to wh-movement is due to different modes of checking off the clausal typing feature in C. Some theoretical consequences of this proposal are that successive cyclic wh-movement can be naturally accounted for in a derivational approach to syntax and that the strength of C is always strong both in English and Korean-type languages.

Jaecheol Lee. 2001. Antecedent Contained Deletion and LF Pied Piping. Studies in Modern Grammar 24, 67-90. In this paper, we prove that LF pied-piping is required for the resolution of Antecedent Contained Deletion(ACD), and that the theory-internal motives for the LF pied-piping results from economy considerations; LF convergence and the Last Resort. ACD resolution requires LF pied piping of an entire phrase out of categories that contain it. We argue that the LF pied-piping movements by Quantifier Raising and Rightward movement are triggered for the purpose of resolving the infinite regress problem in ACD configuration. Both movements are necessary to satisfy Full Interpretation at LF. We propose that QR is driven by a QU-feature, which triggers LF pied-piping of a quantificational expression in ACD configuration. The checking of QU-feature arises because the interpretively redundant QU-features on QP and its target are not allowed at the interface, which result in the violation of the principle of full interpretation. Rightward movement is driven by the Last Resort, chosen only when QR cannot occur in ACD construction.

Hyon Sook Choe. 2001. Focus-sensitivity of Sentence Negation and a Movement Approach. Studies In Modern Grammar 23, 33-74. In this paper, I discuss the nature of the focus-sensitivity of sentence negation under a movement approach In Choe (2000), which adopts the following two assumptions: (1) negation is adverbial, negatively modifying either a focus or a quantifier phrase; (2) it moves for checking reasons. While a examining the counter-evidence against a movement approach discussed in the literature, which has been discussed in relation to two problems (the "constituency" problem and the "subjacency" problem), I show that the counter-evidence is apparent and that it in fact constitutes evidence in favor of the movement approach adopted here. During the discussion, I suggest that the notion of negating be understood in terms of the notions of feature negating and syntactic negating; and I show that the present suggestion makes it possible to understand both the nature of the focus-sensitivity of negation and he syntax and the semantics of negation in relation to various kinds of foci and in relation to a quantifier phrase.

실제 유역에서 강우량 분포는 시·공간적으로 많은 변화가 있으나 유출량 모의시에는 종종 유역내 동일한 강우량이 분포하는 것으로 가정하여 해석하게된다. 그러나 이러한 가정을 가지고 유출을 모의하게되면 그 정확성에 한계가 따르며, 태풍, 사이클론, 허리케인 등에서 종종 일어나는 이동강우의 경우에는 산출된 유출량의 정확성 문제가 더욱 크게 나타난다. 본 논문에서는 GIS기법을 이용하여 1999년 8월 2일 16:00에서 23:00까지 춘양관측소에서 관측된 등우

현재 사용되고 있는 소류사량 산정식들은 형식의 다양함과 관련변수들의 불일치로 각 공식의 특징을 파악하기 힘들며 사용된 관측자료가 다르기 때문에 상대적인 비교가 어렵다. 한편 산정식의 유도과정에서 사용되는 기본적인 가정들의 개선여지가 많은 것으로 판단된다. 이러한 문제점들을 해결하기 위하여 소류사량과 직접적으로 관련된 여러 무차원수들을 제시하고 그들간의 관계식을 도출하였으며 가장 적합하다고 판단되는 무차원수를 도입하여 형식의 통일을 기하였다. van Ri

본 연구에서는 식생된 개수로에서의 난류 구조와 부유사 이동을 수치모의하였다. 난류폐합식으로는 난류모형을 사용하였다. 수치모의를 통해 평균유속, 난류강도, 레이놀즈 응력, 난류에너지 생성 및 소멸의 분포를 계산하였으며, 기존의 실험결과와 비교하였다. 식생에 의한 항력으로 인하여 평균유속이 전반적으로 감소되었으며, 이에 따라 난류강도와 레이놀즈 응력의 분포 역시 약화되었다. 침수식생의 경우, 식생높이보다 높은 구간에서는 전단에 의한 난류에너지 생성이 지배
