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

Ji-Ryong Lim. 2000. Aspects of the Lexicalization of Motion Events in Korean. Studies in Modern Grammar 20, 23-45. The purpose of this study is to show aspects of the lexicalization of motion events in Korean and to determine its language typological status from the viewpoint of Cognitive Linguistics. Linguistically the phenomena of motion are universal, and the constituents of concepts denoting motion events are the same, but aspects of the lexicalization of their constituents are different. Talmy (1985, 1991) distinguished between `verb-framed` and `satellite-framed` languages according to the aspects of the lexicalization of the concepts and in the frame of motion events, and argued that all the languages of the world could be categorized as either of them. In verb-framed languages like French and Spanish, and are conflated in single verbs, and is expressed by an adverbial, while in the satellite-framed languages like English and German, and are conflated in the verbs, and is expressed by satellite words. In the light of Talmy`s (1985, 1991) language typology and the lexicalization of concepts referring to motion events, Korean is neither classified as a verb-framed language, nor as a satellite-framed language. To show this, I classified motion compound verbs ending with `KATA` in terms of their meaning types, and analyze their lexicalization aspects. The results are as follows: First, such meaning information as , , , and , etc. forms a unit in the compound form `((V₃-e)V₂-e)V₁-e+KATA`. Second, the order of such conceptual units in the compound forms of `KATA` is systematically dependent on the layer structure of "CauseㆍManner

For the purpose of development of a liquid membrane permeator which separates metal ions from aqueous solutions continuously and effectively, a continuous membrane permeator with the membrane solution trapped between extraction and stripping phases by two micro-porous hydrophilic films was manufactured. Experimental researches on the separation of zinc ion from aqueous solutions were performed in the liquid membrane permeator with 30 vol % D2EHPA solution in kerosine as liquid membrane. As results, the liquid membrane permeator separates zinc ion from aqueous solutions continuously and effectively in the wide range of operating conditions. A simple mass transfer rate model using equilibrium constant of the extraction reaction for the system used were proposed, and the model was compared with experimental results of separation of zinc ion in the permeator. And the effects of operating factors, such as space time, pH of extraction solution, extraction temperature, on the separation rate of zinc ion in the permeator were experimentally examined.

This study is a suggest a measurement method of lateral displacement, which can be used to judge the stability of bridge abutment on soil undergoing lateral movement. The abutment of bridge on soft foundation makes lateral movement due to the settlement of back fill and lateral flow. To measure the displacement of such a abutment, there are a lot of indirect method for measurement such as survey of leveling or inclinometer gauge around the abutment. But all of them are not sufficient to confirm the ground behavior and measure the exact lateral behavior of structure. As making the structure and pile cooperatively by measuring the movement of lateral displacement, for measuring the abutment displacement precisely by using the inclinometer. In this work, we try to suggest efficient measuring method of abutment displacement and its application.

In this study, the movable bed model testing was carried out so as to analyze bed profile changes including predicting scouring and deposition of bed profile and to solve hydraulic problems affecting with bed and both-bank between upstream and downstream of intake weir in the Nakdong river channel. The movable bed model testing consists of fundamental test, movable model test and numerical analysis method respectively. The fundamental test was enforced to analyze relationship of discharge and sediment load in the tilting flume. When the movable model test was worked, it was shown that sediment budget between input sediment load and output sediment load was balanced exactly. As a result of movable model test, it was presented that scouring and deposition changes in quantities between the upstream and downstream of modification weir were less than those of nature and planning weir. Finally, numerical analysis method was operated by 1-dimensional bed profile changes model ; HEC-6 model so as to complement unsolving hard problems during movable model test. So, modification weir will be sustained the stable bed profile changes than any other weirs in the study channel.

Fritillaria pallidiflora의 전분체 미세구조와 신구인경의 세포간 대사물질의 이동을 전자현미경으로 관찰하였다. 기존의 인경과 새로 형성된 인경세포내 전분체는 내부 막구조에 있어서 뚜렷한 차이를 나타내었을 뿐만 아니라 대사물질의 세포간 이동도 활발히 이루어지고 있음을 관찰할 수 있었다. 엔도사이토시스와 엑소사이토시스 현상이 세포막에서 관찰되었으며 대사물질의 세포간 이동을 위해 원형질 연락에 있어서 염류수송 경로가 형성됨을 알 수 있었다. 또한 일단의 소포체들이 원형질 연락의 말단에 위치하고 있었는데 이는 세포간 물질 이동에 이들이 관여하고 있음을 알 수 있었다. 이러한 결과는 F. pallidiflora의 신구 인경형성과 발달에 미치는 기작을 연구하는데 유용하게 이용될 수 있는 것으로 생각된다.

Lee Jae-Choel. 1999. The Locality Condition of Movement. Studies in Modern Grammar 16, 103-119. The main purpose of this paper is to point out the problems of the shortest move requirement and the Attract-F proposed in Chomsky (1993) and Chomsky (1995) respectively, and to propose an alternative. The existing locality conditions restrict the domain of either the moving elements or the feature checkers. But both approaches cannot explain Islands Violations, Superraing and Crossing Effects. To solve these problems, I argued that the existing Attract-F requirement be maintained as the locality condition of feature checkers, but the Minimal Link Condition be required as independent locality condition of moving elements. In contrast with Chomsky(1995), I assume that [+WH] feature of Wh-phrases is [-interpretable] in order to explain the asymmetries of Islands Violations and Crossing Effects.

An accurate method of estimating ship maneuverability needs to be developed to evaluate precisely and improve the maneuverability of ships according to the water depth. In order to estimate maneuverability by a mathematical model. The hydrodynamic forces acting on a ship hull and the flow field around the ship in maneuvering motion need to be estimated. The ship speed new the berth is very low and the fluid flow around a ship hull is unsteady. So, the transient fluid motion should be considered to estimate the drag force acting on the ship hull. In the low speed and short time lateral motion, the vorticity is created by the body and grow up in the acceleration stage and the velocity induced by the vorticity affect to the body in deceleration stage. For this kind of problem, CFD is considered as a goof tool to understand the phenomena. In this paper, the 2D CFD code is used for basic consideration of the phenomena to solve the flow in the cross section of the ship considering the ship is slender and the water depth is large enough. The flow fields Added and hydrodynamic forces for the some prescribed motions are computed and compared with the preliminary experiment results. The comparison of the force with measurement is shown a fairly good agreement in tendency. The 3D Potential Calculation based on the Hess & Smith Theory is employed to predict the surge, sway added mass and yaw added moment of inertia of hydrodynamic coefficients for M/V ESSO OSAKA according to the water depth. The results are also compared with experimental data. Finally, the sway added mass of hydrodynamic coefficients for T/S HANNARA is suggested in each water depth.

Hee-Rahk Chae. 1999. A Definition and Classification of Locomotion Verbs. Studies in Modern Grammar 15, 79-100. In this paper, we will, firstly, examine morphological, syntactic and semantic issues related to the analysis of locomotion verb constructions. Secondly, after showing that locomotion verbs cannot be properly defined syntactically on the basis of the complements they take, we will provide a semantic definition of them and then a new classification of them. The classification will be based on a couple of parameters: whether the "Figure (moving entity)" is a subject or an object, and whether it is an Agent or not. In providing the definition and classification, we will make it clear that locomotion verbs are different from "motion verbs." In addition, we will factor out a group of "pseudo-locomotion verbs" from the group of locomotion verbs in the traditional sense. Lastly, we will clarify the relationship between locomotion verbs and the -le complement, which is assumed to uniquely characterize the Korean locomotion verbs in syntactic approaches. We will show that there are two groups of verbs which can take the complement (one is a subgroup of locomotion verbs and the other is a group of non-locomotion verbs), and that the complement shows different properties in each of the two groups.

본 연구에서는 동계에 양식어류의 지속적인 성장을 유지시키기 위한 월동장으로서, 하계에 적조발생 해역으로부터의 대피장소로서 이동 가능한 적지를 수산물리 해양학적으로 선정 하고자 하였다. 동계에 월동장으로서는 서식적수온이 10℃ 이상인 어종(넙치, 농어) 경우 거문도, 서이말, 가덕도, 그리고 제주도 주변해역이 적합하였으며, 15℃ 이상인 어종(방어, 참돔, 복어)은 서귀포와 우도(성산포)에서 월동이 가능한 것으로 나타났다. 산지는 동계에 강한 북서계절풍의 영향을 직접적으로 받는 지역으로 표면수온의 변화가 심하여 월동장으로서는 적합하지 않았다. 서식적수온이 각각 18℃ 와 19℃ 이상인 조피볼락과 숭어의 경우에는 성장을 지속시키며 월동할 수 있는 적지를 남해안에서는 찾을 수 없었다. 용존산소의 경우 동계와 하계 모두 전 해역에서 해양생물의 활동을 유지하는데 필요한 4mℓ/ℓ 이상의 농도를 나타내어 양식어류의 이동시 크게 고려하지 않아도 될 것으로 판단된다. 하계에 적조발생 해역으로부터 양식생물을 대피시키기 위한 이동적지로서는 지난 6년 간 적조가 발생하지 않았고, 만일의 경우 적조가 발생하더라도 인근해역으로 대피가 자유로운 거문도와 제주도 주변해역이 적합하였다. 목포주변해역은 조류가 세고, 여자만은 적조발생 시 대피시킬 수 있는 통로가 없어 이동적지로서는 적합하지 않았다.

Four cast iron pipe sections containing 3 styrene butadiene rubber (SBR) gaskets (1 joint and 2 end caps) were filled with water and maintained at approximately 40 psi internal pressure. The pipe sections were placed inside 16 gallon drums filled with initially clean sand. Three of the tanks were subsequently contaminated with gasoline, gasoline spiked with pyrene and naphthalene, and toluene. The forth tank served as a control. The water inside each pipe was monitored over time for organic chemical contamination. Permeation of organic chemicals into the water inside the pipe systems was found to occur in all 3 contaminated pipe systems after approximately 100 days as measured organic chemicals concentrations were significantly above those in the uncontaminated cell. Flushing experiments in which the water inside the contaminated pipes was replaced with initially clean water showed that organic chemical concentrations inside the pipe rapidly (12 days) reached their preflushing levels.

본연구에서는 Einstein과 Chien(1954)의 이론은 토대로 하여 하천의 모형연구에 적합한 이동상 모형이론을 수립하였다. 흐름의 상사 ()와 유사이동의 상사 ()의 변화에 따른 총 하상변동량의 거동을 비교함으로써 적용성을 검토하였다. 그 결과 의 값 또는 의 값이 작을 수록 총 사항변동량은 크게 발생하는 것으로 나타났다. 본 연구에서 수립된 모형이론은 각 모형이론의 제한조건을 완화한 것으로서 실험장소 또는 모형사의 제한으로 모형이론을 이상적으로
