In this paper I applies Borer (1993)'s way of classifying English intransitive action verbs such as 'run', walk, among many others, to the corresponding Korean intransitive action verbs such as 'tali-ta' and 'keət-ta', and show how they are different from - or similar with - each other in terms of syntactic structures and verb classification. Unlike the English verb 'run' which can be classified into an unaccusative verb as well as an unergative verb in Borer's theory, the corresponding Korean verbs 'tali-ta' or 't'wi-ta' can behave not only as an unergative and unauucsative verb, but also it can behave as a transitive verb. Though Borer's perspective on classification of verb types may be thought of as somewhat radical mostly due to its heavy dependency on aspectual representation of a whole sentence which a verb is just part of, it is clearly suggesting a new and great insight into the controversial topic of classification of verb types. So it is worth adopting this insightful perspective for the analysis of corresponding Korean verbs and seeing if it also works for the Korean ones.

The interaction of incident manochromatic waves with an array of N surface-piercing porous dual cylindrical structures is investigated in the frame of three-dimensional linear potential theory. The dual cylindrical structure is camposed of concentric two cylinders. The exterior cylinder is porous and the interior cylinder is impermeable. The fluid domain is divided into N+1 regions i.e. a single exterior region and N interior regions. The diffraction potentials in each region representing the scattering of incident waves by an array of porous cylindrical structures are expressed by the Fourier Bessel series. The unknown coefficients in each region are determined by applying the porous boundary condition and continuity of mass flux at the matching boundary. It is found that an array of porous cylindrical structures reduces both the wave forces and the wave run-up, and shows the excellent performance of wave blocking. The results show that various types of breakwater exchanging seawater are prospective by controlling the porosity and the configuration of cylindrical structures.

본 논문은 방대한 크기의 볼륨 데이타를 효율적으로 렌더링하기 위한 셀 기반 웨이브릿 압축 방법을 제시한다. 이 방법은 볼륨을 작은 크기의 셀로 나누고, 셀 단위로 웨이브릿 변환을 한 다음 복원 순서에 따른 런-길이(run-length) 인코딩을 수행하여 높은 압축율과 빠른 복원을 제공한다. 또한 최근 복원 정보를 캐쉬 자료 구조에 효율적으로 저장하여 복원 시간을 단축시키고, 에러 임계치의 정규화로 비정규화된 웨이브릿 압축보다 빠른 속도로 정규화된 압축과 같은 고화질의 이미지를 생성하였다. 본 연구의 성능을 평가하기 위하여 {{}} 해상도의 볼륨 데이타를 압축하여 쉬어-？ 분해(shear-warp factorization) 알고리즘에 적용한 결과, 손상이 거의 없는 상태로 약 27:1의 압축율이 얻어졌고, 약 3초의 렌더링 시간이 걸렸다.Abstract This paper presents an efficient cell-based wavelet compression method of large volume data. Volume data is divided into individual cell of {{}} voxels, and then wavelet transform is applied to each cell. The transformed cell is run-length encoded according to the reconstruction order resulting in a fairly good compression ratio and fast reconstruction. A cache structure is used to speed up the process of reconstruction and a threshold normalization scheme is presented to produce a higher quality rendered image. We have combined our compression method with shear-warp factorization, which is an accelerated volume rendering algorithm. Experimental results show the space requirement to be about 27:1 and the rendering time to be about 3 seconds for {{}} data sets while preserving the quality of an image as like as using original data.

We have examined its current economic conditions and status of the Bangsamoro in Mindanao and derived some important policy recommendation to build the future development plan. For this purpose, we first estimate the economic size and GRDP per capita and investigate next several economic and social indicators such as poverty rate and industrial structure. We find that the Bangsamoro is the least developed region in Philippines whose average income is the lowest and whose poverty rate is the highest in the Philippines. In addition, its industrial structure is very falling behind. Applying simple theory of economic growth, we find that several economic reasons such as lack of private and public investment caused by the political instability, high illiterate rate and less education, incapability of local government account for it. As a result, several policy recommendations are suggested to make the development plan of the Bangsamoro. First, the plan should be very comprehensive and second, it should be a very sustainable one equipped with the long run one and short run one. Third, the plan should be harmonized with that of the central government and those of neighboring local governments. Fourth, it should exploit the assistance of international development organization.

This paper proposed the low power texture cache for mobile 3D graphics accelerators. It is very important to reduce the leakage power in the standby mode for mobile 3D graphics accelerators and the memory access latency of texture mapping in the active mode which needs a large memory bandwidth. The proposed structure reduces the leakage power using variable threshold values of power mode transitions according to the selected texture filtering algorithms of application programs, which has the run time gain for texture mapping. In the trace driven cache simulation the proposed structure shows the best 7% performance gain to the previous MSA cache according to the new performance metric considering both normalized leakage power and run time impact.

The purpose of this paper is to investigate the Balassa-Samuelson effect that real exchange rate could deviate from its long-run equilibrium. To analyze this effect, I estimated the long-run relationship between real exchange and productivity using the dynamic panel ordinary least square(DOLS) and panel error correction model(ECM) after conducting the unit root and cointegration test. The results show that all variables except for the real exchange rate have the unit root. Then I conducted the cointegration test to find out whether there exist the stable long-run relationships. The results show that the variables are cointegrated and significant statistically. The DOLS and ECM methods are used to estimate the coefficient of the cointegrated variables. The major finding are that the estimates are statistically significant and that they show the same sign as the economic theory predicts.

Although Korea is short of capital technology, and natural resources, she has achieved an outstanding progress by the export-drive policies by Korean government and the creative endeavor of Korean firms. As a result of that, Korean economy and enterprises are in the same file of newly industrialized countries and Korea is ready for an economic take-off as a developed country. But in the early 1980s, each country strengthens protective trade theory and resources nationalism, and this has a great influence on the field of international trade environment. In spite of that, to continue the same high development as that of the past. Korea must try to secure and find export markets, solve trade barriers, make sure of the long-term security of resources, develop technology, and strengthen economic cooperations. To satisfy these desires by 2000s, we must try to make Korean enterprises have the global competitive power and them grow strongly among world wide firm through capital and technology accumulated during the passed years, and to do so, there must be a foreign production and marketing management, too, this can be achieved only through foreign overseas direct investment. This investment has various forms, to say, verifical integrated, horizontal integrated. conglomerate integrated forms, and the amount of investment in each country from 18 century to today reaches 500 billion dollars. This investment is done by strategic, behavioral economic, and financial motives. So I am going to approach the fields of like these; in spite of the differences among political, economical, caltural, and social systems, and many risk compared with domestic enterprises, why do Korean firms witsh to transfer the productive facilities to overseas countries and run them there? What is the comparative advantage of foreign direct investment compared with domestic investment ?. why is the factor of comparative advantage transferred through foreign direct investment?, what is the motive of foreign overseas direct investment?, and last the ownership-specific factors and the theory of internalization, and the location specific factors were analysed chiefly. But in consideration of the given condition in Korea, Korean overseas direct investment must be propelled rationally on the basis of the above mentioned theory.

This research examines the relation of dissatisfaction about own real conditions, deviant labeling, self-esteem, abuse from parent, victimization and juvenile delinquency(smoking, drinking, run-away, assault, taking away stuffs or money, larceny). The evidence of a strong relation of these factors and girls' delinquency is well known through empirical researches by feminist criminologists. Feminist criminology had attention to the gender-specific factors that could explain girls' delinquency. Most of conventional delinquency theories, such as social bond theory, differential association theory, focused on bad boys' deviant behaviors. These theories has not been designed to apply to girls' troubles. According to the conclusion of the research, there seems to support researches of feministic perspectives.

This study attempted to introduce Fei-Ranis's agricultural development theory and discuss its problem for the rural development of less developed world. Fei-Ranis systematized the development process of Western European economy on the ground of dualism. They divided the process into 4 stages by the concept of 'mode of operation'. Paticularly, they consider agrarian mercantilism as take-off stage and its development were achieved by the increase of trade margin and labor productivity. Especially, they thought that only agricultural revolution through the diffusion of internal exchange economy and construction of tree-star system can accomplish favorable transition to industrial capitalism. In order to promote this agricultural development, less developed world must abolish short-run agricultural policy and propel 'learning by the contact' strategy through 'tree-star system' and 'parellel development.' In reality, it was problematic that the contemporary less developed world is trying, in the course of a few decades, to imitate Western European experience with development over the last four centuries. But Fei-Ranis ignored qualitative aspects of agricultural development by tree-star system and also it is criticized that they considered agricultural development process of less developed world follows only that of Western European classical process.

The d-q harmonic detecting algorithms are dominant methods to generate current references for active power filters (APF). They are often implemented in the synchronous frame and time domain. This paper researches the frequency characteristics of d-q synchronous transformations, which are closely related to the analysis and design issues of control system. Intuitively, the synchronous transformation is explained with amplitude modulation (AM) in this paper. Then, the synchronous filter is proven to be a time-invariant and linear system, and its transfer function matrix is derived in the stationary frames. These frequency-domain models imply that the synchronous transformation has an equivalent effect of frequency transformation. It is because of this feature, the d-q method achieves band-pass characteristics with the low pass filters in the synchronous frame at run time. To simplify these analytical models, an instantaneous positive-negative sequence frame is proposed as expansion of traditional symmetrical components theory. Furthermore, the synchronous filter is compared with the traditional bind-pass filters based on these frequency-domain analytical models. The d-q harmonic detection methods are also improved to eliminate the inherent coupling effect of synchronous transformation. Typical examples are given to verify previous analysis and comparison. Simulation and experimental results are also provided for verification.
