  • For the purpose of analyzing the influence of the recent environmental changes of container logistics system in container terminal, the simulation model of container logistics system on BCTOC is developed in this paper. The simulation model is accomplished by the AweSim simulation language, and the several data which have been used in simulation gained through spot research and basic statistic analysis using the first half of 1998 electronic data in BCTOC. The results of this study are as follows; (1) In the case of BCTOC, the decreasing of container volumes is observed during the first half of 1998 compare with that of 1997. (2) In the container handling service market, the monopolistic market system in the past rapidly diverts to the competition market system from now. (3) From the simulation results, the improving of container logistics system is observed. (4) Because of these results, BCTOC will come to strengthen customer service and competitive power through starting On-Dock service system and operating the team of customer management in the long term.

  • The use of a microporous membrane along with Au/C catalyst for direct glycerol alkaline fuel cell was investigated. In comparison with Nafion 112, the microporous Celgard 3401 membrane provides a better cell performance due to the lower ionic resistance as confirmed by impedance spectra. The single cell using Au/C as anode catalyst prepared by using PVA protection techniques provided a higher maximum power density than the single cell with commercial PtRu/C at $18.65mW\;cm^{-2}$ The short-term current decay studies show a better stability of Au/C single cell. The higher activity of Au/C over PtRu/C was owing to the lower activation loss of Awe. The magnitude of current decay indicates a low problem of glycerol crossover from anode to cathode side. The similar performance of single cell with and without humudification at cathode points out an adequate transport of water through the microporous membrane.

  • 본 논문에서는 고속 ATM 스위치에 적합한 셀 스케줄링 알고리즘을 제안하고 있다. 제안한 셀 스케줄링 방식은 기존의 FRR(Fixed weight Round Robin: 고정 가중치 라운드 로빈) 방식과 QLT(Queue Length Threshold) 변형방을 결합한 가변 가중치 라운드 로빈(VRR: Variable weight Round Robin) 셀 스케줄링 방식이다. FRR 방식은 각 버퍼별로 고정 가중치를 부여하여 고정 라운드 로빈 방식에 의해 셀 스케줄링을 수행하므로 고속 스위치의 구현 관점에서는 매우 큰 장점을 지니고 있지만 ATM 서비스 클래스들이 요구하는 QoS를 만족시키거나 네트워크 상황에 융통성 있게 대처할 수는 없으므로 VRR 방식은 FRR 방식을 기반으로 고정 가중치를 수행하고 버퍼 상황에 따라 가변 가중치로 확장하는 방식을 적용하여 셀 손실 QoS를 향상시키면서 셀 지연률 QoS를 만족시킬 수 있는 방식임을 시뮬레이션을 통하여 입증하였다.

  • The next generation of optical storage systems requires higher numerical aperture (NA) objective lenses and shorter wavelength laser in order to improve the unit areal density. A blu-ray technology satisfies a miniaturization and a high capacity which are the requirements of the portable device. In this paper, we analyze the optical performance of hybrid micro lens and do active alignment. The hybrid micro lens is manufactured by using a wafer based fabrication technology. Optical components of hybrid micro lens are evaluated. The measurement of the optical power, the spot size and the wavefront error awe performed to evaluate the hybrid micro lens with NA 0.85. Using the measured data, we estimate if the performance of hybrid micro lens corresponds to the designed performance. After the performance of hybrid micro lens is evaluated, the integrated optical pickup and the hybrid micro lens are assembled by active alignment using UV curing and the optical performance of SFFOP is satisfied with BD specifications.

  • The very definitions of posture and balance have changed, as has our understanding of the underlying neural mechanisms, In rehabilitation science, there awe at least two different conceptual theories to describe the neural control of posture and balance : the reflex/hierarchical theory and system theory. A reflex/hierarchical theory suggests the posture and balance result from hierarchically organized reflex responses triggered by independent sensory systems. The systems approach suggests that action emerges from an interaction of the individual with the task and environment. That is to say, the systems approach implies that the ability to control our body's position in space emerges from a complex interaction of musculoskeletal and neural systems, collectively referred to as the postural control system. The specific organization of postural systems determined both by the functional task and the environment in which it is being performed, The postural control system is divided into three basic functional components for assessment : 1) musculoskeletal components, 2) motor coordination components, and 3) sensory organization components. It is proposed that a systemic functional understanding of human balance is critical to effective programs for balance rehabilitation. Thus, this article briefly reviews the basic functional components to consider in designing treatment plan and for the benefit of the balance assessment.

  • Luxury fashion brands have begun to aggressively introduce art to justify inherent values such as tradition, craftsmanship, and exclusivity that make it difficult for luxury brands to uphold awe-inspiring atmosphere. Artification refers to a process in which non-artistic factors are transformed into art or artistic category under the influence of artistic thoughts or actions. In addition, the consumption space provided by brands have become important as the importance of substantial shopping experience has increased. Especially, since the artification is actively utilized in flagship stores in the communication interface with consumers. This study uses a literature review and case studies to typify and derive the meaning of the method for artification at a flagship store that effectively conveys brand identity and value. The types of artification at a luxury fashion brand flagship store are divided into pursuing brand permanency and maintaining brand exclusivity that also provides a new value of permanency like a work of art to a luxury fashion brand. Basic values, such as scarcity are declining, reviving and justifying the value threatened by the popularization of luxury.

  • The economic decline coincided with the crooked political path of Spanish monarchy that has been on an almost permanent state of war. The Spanish empire was divided and consequently, general impoverishment spread throughout the whole country quickly. Nevertheless Spanish culture reached the climax, especially in the field of painting. Spanish paintings of 17th century are basically religious based on concept of Baroque, whose theme is usually the immaculate conception or mysterious figures of saints. Velaquez, Mrillo, and Ribera are the main painters who represented the trend of this time. Despite having fame as religious court painters, they painted subjects from low society such as beggars in rags, dwarves, jesters, or the poor child. They reflected an optimistic expression and an awe for human being in their paintings greatly. In this paper, we are dealing with three main representative painters of Baroque era whose theme was a picaresque character. This character was one of the axes that coexisted with royals and nobles in 17th century of Spain. The art works that are dealt in this paper serve as materials for historial values and through them we can observe the atmosphere of decline that dominated Spain of the time.

  • Walter Benjamin expresses his concern that the new technologies of mechanical reproduction robs the artwork of its own uniqueness, its "aura." Benjamin uses the word "aura" to refer to the sense of awe or reverence one presumably experiences in the presence of works of art. This aura does not merely inhere in the works of art themselves, because Benjamin extends his notion of aura to the level of how he both understands and positions the modern subject in the world of uncertainty and transitoriness. The theoretical framework of Benjaminian aura becomes a crucial and efficient strategic apparatus to read The Education of Henry Adams. As for Benjamin the modern implies a sense of alienation, a historical discontinuity, and a decisive break with tradition, Adams observes that modern civilization has wiped out "tradition," a mythic home in which man can experience order and unity. Adams claims that the growth of science, reason, and multiplicity at the expense of religion, feeling, and unity has been accompanied by a parallel growth in individualism at the expense of community and tradition. To Adams the collapse of traditional values such as maternity, fecundity, and security in America is a waking nightmare of the moral dilemmas of a capitalist society, in which the cruel force of the modern Dynamo is becoming a prime governing principle.

  • 본 연구에서는 기상 자료와 적설 특성 자료의 관계를 도출하고, 이와 추계 일기 생성 모형을 활용하여 합성 적설심 시계열을 모의하는 방법에 대하여 제안한다. 추계 일기 생성 모형에서는 적설량을 직접 모의하지 않기 때문에 강수량을 적설량으로 변환해야한다. 이를 위해 도입한 관계식은 다음과 같다. 첫째로 기상청 적설 예보의 적설 유무 판단 기준을 이용하였다. 이 기준에서는 상대습도와 지상기온에 따라 강수의 형태를 비, 눈, 진눈깨비로 구분한다. 둘째로 강수가 적설로 판단되었을 때 강수량을 신적설심으로 환산하는 수상당량비를 지상기온과 회귀 분석하였다. 선행 연구에 따라 3시간 1 mm 이상 5 mm 이하 강수와 3시간 5 mm 이상 강수 사상에 대하여 나누어 sigmoid형 곡선을 이용하여 회귀 분석하였다. 마지막으로 융설에 의한 적설심 감소량을 지상기온과 복사량의 함수로 표현하였으며, 각 변수의 계수는 입자 군집 최적화 방법을 통하여 보정하였다. 추계 일기 생성 모형으로는 AWE-GEN 모형을 활용하였으며, 시험 자료로 강릉(105) 종관기상관측소의 24년 기간(1982-2005) 자료를 활용하여 합성 적설심 시계열을 생성하였다. 합성 적설심 시계열 모의 과정은 다음과 같다. (1) 추계 일기 생성 모형으로 합성 일기 자료 생성, (2) 강수 발생 시 적설 유무 판단, (3) 적설로 판단 시 수상당량비를 계산하여 신적설심 추정, (4) 기존 적설심에 신적설심을 더하고, 적설심 감소량만큼 감소. 위와 같은 과정으로 200년 길이 합성 적설심 시계열을 모의한 결과 극한 사상을 과소 추정하는 경향이 나타나 추가적인 개선이 필요한 것으로 판단된다.

  • 행복은 대인관계 측면에서 긍정적인 결과를 산출한다. 그러나 구체적으로 행복한 사람들의 어떤 대인행동이 관계적으로 긍정적 결과를 도출하는지에 대해서는 연구된 바가 많지 않다. 상호작용 시 상대방에게 지지적인 정서를 표현해주는 것은 관계의 형성과 만족에 중요한 역할을 한다. 본 논문에서는 두 개의 연구를 통하여 고각성의 긍정적 정서인 '즐거움'이 상호작용 시 상대방에 대한 지지적인 정서 표현을 유발하는지 알아보고자 한다. 연구 1에서는 긍정적 정서가 성격과 인지적 요인을 통제한 뒤에도 여전히 유의하게 지지적 정서 표현을 예측하였다. 긍정적 정서의 이러한 효과는 고각성 정서로 인한 것이었다. 연구 2에서는 '즐거움'이 유발된 참가자들이 '자랑스러움', '경이로움', '편안함'이 유발된 참가자들에 비해 타인의 이야기에 적극적으로 정서를 표현하고 상대를 지지하였다. 본 연구는 긍정적 정서가 대인 관계에 어떻게 이득을 주는지에 대한 단서를 제공함과 동시에, 그 중에서도 특히 '즐거움'이 사회적 관계 형성을 촉진하기 위해 진화되었을 가능성을 제안한다.
