후쿠야마가 1989년 "역사의 종언"을 선언한 이후에도 자유민주주의에 대한 도전은 끊이지 않고 있다. 미중 패권 전쟁은 물론 전 세계적으로 민주주의 체제를 표방하는 국가나 지도자들에 대하여 대내외적으로 전체주의나 전체주의자라는 논란이 끊임없이 제기되고 있다. 본 논문에서는 민주주의 국가의 전체주의화 과정에 대한 가설을 모색해 보고, 이 가설을 설명하기 위해 한 때 복지모범국가로 회자되다가 전체주의국가로 추락한 베네수엘라를 사례로 분석해 보고자 하였다. 이를 위해 본 논문에서는 역사철학적으로 자유민주주의의 보편성에 대해서는 후쿠야마의 주장을 전제로 하나, 그가 가정하는 최후의 인간에 대해서는 니체가 주장하는 최후의 인간을 고려하였다. 이에 따라서 민주국가의 전체주의화 과정은 국제적 및 국내적 환경 속에서 타락한 최후의 인간, 대중, 전체주의자의 연계와 상호작용을 통하여 전체주의가 제도화되고 국제적으로 확산되는 과정으로 보았다. 이러한 가설에 따라 베네수엘라와 차베스의 볼리바르 혁명은 전형적인 유사전체주의로의 변화 과정을 보여 준다. 베네수엘라의 국민은 비록 민주주의와 시장경제를 선호하면서도 "부자의식"에 찌든 최후의 인간에 머물렀다. 이러한 가설을 연구하면서 디지털 전체주의 등 수많은 변수와 과학기술의 발전 등 광범위한 학제적 연구가 후속되어야 한다는 점을 확인할 수 있었다.

Biological pump processes generated by diatom production in the surface water of the Southern Ocean play an important role in exchanging CO₂ gas between the atmosphere and ocean. In this study, the biogenic opal content of the sediments was measured to elucidate the variation in the primary production of diatoms in the surface water of the Southern Ocean since the last glacial period. A piston core (COR-1bPC) was collected from the Conrad Rise, which is located in the Indian sector of the Southern Ocean. The sediments were mainly composed of siliceous ooze, and sediment lightness increased and magnetic susceptibility decreased in an upward direction. The biogenic opal content was low (38.9%) during the last glacial period and high (73.4%) during the Holocene, showing a similar variation to that of Antarctic ice core ΔT and CO₂ concentration. In addition, the variation of biogenic opal content in core COR-1bPC is consistent with previous results reported in the Antarctic Zone, south of the Antarctic Polar Front, in the Southern Ocean. The glacial-interglacial biogenic opal production was influenced by the extent of sea ice coverage and degree of water column stability. During the last glacial period, the diatom production was reduced due to the penetration of light being limited in the euphotic zone by the extended sea ice coverage caused by the lowered seawater temperature. In addition, the formation of a strong thermocline in more extensive areas of sea ice coverage led to stronger water column stability, resulting in reduced diatom production due to the reduction in the supply of nutrient-rich subsurface water caused by a decrease in upwelling intensity. Under such environmental circumstances, diatom productivity decreased in the Antarctic Zone during the last glacial period, but the biogenic opal content increased rapidly under warming conditions with the onset of deglaciation.

개인형 이동장치에 대한 관심은 스마트 모빌리티 서비스에서 first-mile 및 last-mile 중요성이 증가함에 따라 높아졌다. 본 연구는 first-mile 및 last-mile 문제를 해결하기 위해 자유 주차방식(free-floating) 개인형 이동장치 공유 서비스 권역 설정 방법론을 제시하고 선정된 공유 서비스 권역을 대상으로 최적의 개인형 이동장치 운영 대수 결정을 목표로 한다. 인구 데이터, 스마트 카드 데이터, 건물 데이터를 사용하였으며, 개인형 이동장치 데이터를 이용하여 연령별, 거리별 이용률을 반영하여 잠재수요를 추정하였다. 추정된 잠재수요와 함께 대중교통 정류장과 건물의 위치를 기반으로 개인형 이동장치 공유 서비스 권역을 설정하였다. 인천 영종도를 대상지로 제안된 방법론을 적용한 결과 거주지가 밀집된 지역과 여행객들이 많은 해변 근처가 개인형 이동장치 공유 서비스 권역으로 선정되었다. 거주지가 밀집된 서비스 권역의 개인형 이동장치 운영대수는 1,022대, 해변 근처 서비스 권역의 개인형 이동장치 운영대수는 269대로 결정되었다.

Since Goldreich and Julian's pioneering work in 1969, the pulsar magnetosphere theory has been dramatically developed for theorists to possess an elegant axisymmetric, stationary model. Based on this development the black hole magnetosphere theory has also been established in the last 30 years. Such theoretical developments will be reviewd equation by equation in this paper.

Producer prices of raw milk include following elements: a basic price, payment according to fat content, payment according to bacteriological quality and somatic cell count. The quality of raw milk has increased since last change of payment system according somatic cell count. But last change of payment system according to fat content is not effective. It is necessary to widen the range of equal price by fat content. Also it is necessary to include payment according to protein content.

Assuming that the solar activity and the solar cycle phenomena may be manifestations of global torsional MHD oscillations, we compute the Alfven wave travel times along the field lines in the five models of magnetic field described in the following text. For all these models, we compute standard deviation and it's ratio to mean Alfvenic wave travel times. The last two models yield the smallest relative bandwidth for the frequencies of the MHD oscillations. However, the last model is the only admissible one which can sustain global Alfvenic oscillations with well defined frequency for the fundamental mode

Korean footwear industry has experienced rapid growth and decline during last 30 years. The purpose of this paper is to analyse the main reason for the decline of Korean footwear industry by examining the process of technological learning which Korean footwear firms experienced during last 30 years of OEM. Before this analysis is done, innovation patterns of world footwear industry is sketched to compare with those of Korean footwear industry. On the basis of the analysis on the reasons for decline, I suggest some policy recommendations.

In the last paper, we have discussed the cannonical representatin of a dynamic linear model, on which some aggregation schemes were devised. The relationships of those aggregation schemes with dynamic properties were investigated. This paper tries to analyse she control strategy for the aggregated linear dynamic model and to investigate the dynamic properties of disaggregative model controlled by aggregated model. For the logical consistency with the last paper, all the sections and all the equations are numbered in a sequence.

This thesis, based on the semiotic theory, compared the meaning of sign which is a grounding the military uniform of the category of clothings as a cultural sign for formative relation. As for the scope of study, I made the Amy's uniforms during the last period of Korea Empire from 1895 to 1909 as an object of amy thesis and analyzed their decument and photographes. As a result of analyse of military uniform during by semiotical application, I made clear that it has role of signal by underlying signal's aspect of sign, and it si a sign which could symbolize the class, national and periodical distinction.
