고속도로 교통류 제어는 기존의 Reactive 방식(실시간 대응)에서 Proactive 방식(사전 대응)으로 발전하고 있다. 첨단 고속도로 교통류 제어의 핵심 입력자료 중 하나는 여러 시간대에 걸치는 장래 교통량 상태이다. 다중 시간대 교통량 예측을 위해서는 장래 상태의 불확실성을 극복해야 한다. 이는 예측 시간대의 확장에 따라 장래 상태의 불확실성은 증가하기 때문이다. 따라서 다중 시간대 교통량 예측을 위해서는 장래 상태의 불확실성을 효과적으로 극복할 수 있는 실행 가능한 방안이 필요하다. 본 연구에서는 대용량 이력자료에 내재된 교통류 상태의 시간적 진화 행태를 이용하여 장래 상태의 불확실성을 효과적으로 극복함으로써 다중 시간대 장래 교통량 상태를 예측하는 모형을 제시하도록 한다. 개발 모형은 현행 교통량의 상태 진화를 기반으로 대용량 자료에 내재된 과거 상태를 추출하고, 이를 이용하여 장래 상태를 예측한다. 추가로, 개발된 모형은 실제 적용을 고려하여 자료관리시스템에 적합하도록 설계되었다. 적용결과, 개발모형은 다중 시간대에 걸치는 불확실성을 효과적으로 극복함으로써 우수한 예측력을 보였으며, 첨단자료관리시스템에 실제 적용이 가능하다고 판단된다.

Ancient Greece was a patriarchal society that distinguished gender roles between men and women. Although their costumes were composed of simple rectangular fabric without any technical complications in itself, the Greeks did try to express gender differences in their clothing. The final look of the Greek costume was dependent on the way the cloth draped onto its wearer as well as the wearer's identity. Greeks costume could just be seen as a rectangular fabric when it was not draped on a person's body. The purpose of this study is to examine how the gender differences were expressed in the ancient Greek drapery costume, which was made by using a completely different technical process, compared with the modern tailored costume. There are four elements of the costume that give the costume its formative shape, which are the wearer's body, the rectangular fabric (material as the first formative costume), the way the fabric is draped, and the final appearance as the second formative costume (the relationship between the wearer's body and the costume) and this study analyzes these elements individually. It is intended to analyze the gender characteristics and how each element appears in a different way from the perspective of Structuralism, an analytical method that considers a phenomenon as a total sum of the elements. Literature research was conducted and representative sculpture, painting and pottery, were used between the Archaic Period (B.C. 800~500) and the Classical Period (B.C. 500~323). The results show that the gender differences appear in each formative element of costume: First, the body was distinguished by the ancient Greek custom. The man's nudity was accepted while the woman's body was concealed. Second, in regards to the first formative costume, which was the rectangular fabric, men's were made with thick high quality wool because their involvement in outdoor activities meant that they needed clothes to stay warm, while the women wore clothes made of thin wool or hemp cloth, because their most of their activities were at home. Third, the way to drape the fabric shows the gender differences by changing the length of the clothing and its design ; men's short khiton was practical for big movement and at the same time the clothing exposed the man's body. The woman's doric khiton diversified its decoration by the size of the apotigma and by using the belt. Finally the second formative costume reflected the Greeks' social distinction between a man's body and a woman's body. The man's costume naturally exposed the man's body. On the other hand, the woman's long costume has a variety of shapes on the ground, that concealed her lower body, while the ornamental function was more accentuated than the man's costume. The gender differences expressed in Greek costume fundamentally reflected the point of view of the male and female body and their social roles in society.
