최근 로봇에 관한 연구가 꾸진히 진행 중인 가운데, 로봇이 현재 상황을 파악하고 적절한 서비스를 제공해 주기 위하여 위치 정보가 많이 활용되고 있다. 이러한 위치 정보는 월드 모델링(world modeling)을 통하여 로봇이 처한 환경에서 사용자(nomadic human)의 위치 경로와 공간에 구성되어 있는 객체들의 위치를 비교하거나 관계를 탐지하고 적절한 규칙을 사용해 추론함으로써 사용자의 서비스 요청을 수행하기 위해 쓰일 수 있다. 본 논문은 로봇 환경에서의 상황인지를 위한 월드 모델링을 제안한다. 제안된 월드 모델링은 로봇과 사람과의 관계와 사랑과 사물(object)간의 관계를 정의하며 시간의 흐름에 따른 위치변화를 이용하여 각 대상간의 관계의 변화와 그에 따른 의미(semantic) 도출을 목적으로 한다. 본 시스템은 크게 네 개의 계층으로 구성되어 있다. 첫째, 센서 계층(Sensor layer)은 센서로부터 객체의 위치정보를 얻어내어 센서 데이터를 구성한다. 둘째, 질적 관계 계층(qualitative layer)은 센서 데이터를 기반으로 하여 객체간의 상대적인 위치 관계를 탐지한다. 셋째, 시공간적 관계 계층(relational layer)은 시간에 따라 축적되는 질적 관계 계층의 데이터를 기반으로 하여 객체간의 시간적, 공간적인 위치 관계를 추론한다. 마지막으로 의미적 계층(semantic layer)에서는 객체간의 상황에 맞는 의에를 추론하는데 이런 계층들은 모두 월드 모델을 공유(share)함으로써 정보 도출이 가능하다.

The Purpose of this study is to analyze the clothing excavated in Xinjinag, concerned with the study of clothing culture in Central Asia. The results are as follows : A headwear is a corn hat or round hat, the material is field, fur or woolen textiles. For hair accessories, feathers or wooden pins were used. The corn hats of the Scythians and the Huns also had same design and did not change even after being influenced from the culture of Han Dynasty. A woman's hair styles was many strips of braid, a man's hair style was a braid or a topknot. Regarding the clothing, a woman wore pull-over type and a man wore caftan for a jacket. Both a man and a woman wore widened coat and trousers as well as felt socks and leather boots, and longer socks than boots are the characteristics of the clothing of nomadic horsemen. The textiles was mainly wool, but silk was used for coats, socks and gloves in high society imported from China through the Silk Road after the 2nd century B.C. Compared with Korea clothing, a corn hat, widened coat, trousers and leather boots are similar with those of Koguryo. The influence of western culture is shown in a man's short hair, animal design, W1-Kum, a woman's pull-over type and a round neckline.

The costume style of Turfan had changed three times which were the period of peculiar style the period of Kochang style the period of influence of T'ang's culture. Before the founding of Kochang country the costume style of Turfan was two piece style. It was a character of nomadic people's clothes. Tops were tunic and caftan. The method of adjust caftan were two types. The one is wrapping toward left so the right edge of the top covers the left. The other is wrapping toward right. Bottoms were pants and skirts. This period was characterized by the traditional style. I called in it the period of peculiar style After the founding of Kochang country style as Kochang style. In this period Silkroad was so activated that cultural exchanges between many people and materials passed through Turfan. Turfan's culture soaked up the products of civilization of chinese and western Turkestan. Chinese and western Turkestan's costume influencd under the direct control of T' ang dynasty. Such an aspects were reflected the Trufan's costume. The Trucan's costume had changed into the foreign style that was the T'ang's costume. It was the period of influence of T'ang culture.

In Scythian art the multitude of animal representations well illustrates the preoccupation of this nomadic people with animals in their environment. Usually only wild animals are represented. The purpose and meaning of the animal motifs used in Scythian ornaments appears that in some cases the work was intended to be purely ornamental, while many times the motifs had symbolic meaning (such as the successful dominance of the aggressor over the victim portrayed in the attack scenes). Following earlier Scythian migrations, Sarmatian animal-style art is distinguished by complex compositions in which stylized animals are depicted twisted or turned back upon themselves or in combat with other animals. Without copying nature, they accurately conveyed the essence of every beast depicted. Scythian bound the leather belts that was hanged a hook that shaped of different kinds at the end on the upper garment. Through the antique records and tombs bequests the styles of Scythian Buckles was divided into six groups, animal-shaped, animal's head shaped, animal fight-shaped, rectangle-shaped, rectangle openwork-shaped, genre scene shaped Buckle. In Korea, through the antique records and tombs bequests the styles of Buckles was horse-shaped and tiger-shaped Buckles that were influenced by scythe style.

Ubiquitous computing technologies become mature enough to be applied in acceptable ubiquitous services. In particular, in u-shopping area, personalized recommender systems which automatically collect the nomadic user-related context data and then provide them with products or shops in a flexible manner. However, legacy cooperative queries and context-aware queries so far do not come up with dynamically changing situations and ambiguous query commands, respectively. Hence, The purpose of this paper is to propose a personalized context-aware cooperative query that supports a multi-level data abstraction hierarchy and conceptual distance metric among node instances, while considering the user's context data. To show the feasibility of the methodology proposed in this paper, we have implemented a prototype system, CACO, in the area of site search in a large-scale shopping mall.

Non-geometric shapes in contemporary architecture was explained from the transcendental schema of Deleuze with his abstraction theory. In this explanation, the intensity, the movement and change and the sublime were suggested as the expressional elements of the transcendental abstraction related with the artistic sensation of architecture. First, the intensity as a power of sensation which acts to the body before the recognition of brain is mainly expressed with the movement of curved lines of architectural space. Second, the movement of change is expressed as the de-centralized and de-formalized nomadic curve as the line in architectural 'smooth space' which has unrestrained orientations. Third, the sublime is expressed in the hugeness, enormousness or sometimes uncanny in void space, which could be contradictively mixed with senses of displeasure and pleasure. The sublime feelings in architecture can be emerging by rationally overcoming the unpleasant senses of contradictive spaces in architecture or urban fabric. This study has explained those expressional elements with the architectural works of Steven Holl, Frank Gehry and Zaha Hadid.

The study of the meaning of learning began with the question of what causes people to start learning. Learning is humanization and personification. Learning is a basic human instinct, and the essence of learning is to understand other people and my life, learn community, and learn social capital. Learning gives humans nomadic judgment and provides an opportunity for a productive life for mankind, who must live in constant harmony with the social environment. Learning provides opportunities for self-management, communication with various generations, and self-actualization.

In Written on the Body, by creating the narrator's ungendered and unsexed identity, Winterson makes her text open to the reader's assumption of the narrator's sexual and gender identity. Thus, this novel has been read, on the one hand, as a lesbian text by those who assume that the narrator is a female and, on the other hand, as a suspicious text colluding with patriarchal and heterosexual values by those who define the narrator as a male. Those readings of the narrator as one of either sex/gender, however, demonstrate how (academic as well as general) readers have been accustomed to the gender-based reading habits in which textual meanings are dichotomously arranged along the lines of sex and gender of characters. Challenging those dualistic "gendered" readings, this paper reads Winterson's Written on the Body as a queer text which interrogates, troubles, and subverts the heterosexual concepts of narrative, desire, and body without reducing the narrator's identity to the essentialist sex and gender system. More specifically, this paper examines how the narrator's 'un-/over-' determined sexual and gender identity queers the narrative structure of author-character-reader; how the narrator's queer (fluid) desire is passing and traveling across categorical contours of (homo-/hetero-) sexual desires; how Winterson challenges the concept of a coherent body and queers the concept of body as a hermeneutic text with myriad textual grids which are not coherently mapped by power but randomly inscribed by nomadic desires.

The advent of 5G mobile communications, which is expected in 2020, will provide many services such as Internet of Things (IoT) and vehicle-to-infra/vehicle/nomadic (V2X) communication. There are many requirements to realizing these services: reduced latency, high data rate and reliability, and real-time service. In particular, a high level of reliability and delay sensitivity with an increased data rate are very important for M2M, IoT, and Factory 4.0. Around the world, 5G standardization organizations have considered these services and grouped them to finally derive the technical requirements and service scenarios. The first scenario is broadcast services that use a high data rate for multiple cases of sporting events or emergencies. The second scenario is as support for e-Health, car reliability, etc.; the third scenario is related to VR games with delay sensitivity and real-time techniques. Recently, these groups have been forming agreements on the requirements for such scenarios and the target level. Various techniques are being studied to satisfy such requirements and are being discussed in the context of software-defined networking (SDN) as the next-generation network architecture. SDN is being used to standardize ONF and basically refers to a structure that separates signals for the control plane from the packets for the data plane. One of the best examples for low latency and high reliability is an intelligent traffic system (ITS) using V2X. Because a car passes a small cell of the 5G network very rapidly, the messages to be delivered in the event of an emergency have to be transported in a very short time. This is a typical example requiring high delay sensitivity. 5G has to support a high reliability and delay sensitivity requirements for V2X in the field of traffic control. For these reasons, V2X is a major application of critical delay. V2X (vehicle-to-infra/vehicle/nomadic) represents all types of communication methods applicable to road and vehicles. It refers to a connected or networked vehicle. V2X can be divided into three kinds of communications. First is the communication between a vehicle and infrastructure (vehicle-to-infrastructure; V2I). Second is the communication between a vehicle and another vehicle (vehicle-to-vehicle; V2V). Third is the communication between a vehicle and mobile equipment (vehicle-to-nomadic devices; V2N). This will be added in the future in various fields. Because the SDN structure is under consideration as the next-generation network architecture, the SDN architecture is significant. However, the centralized architecture of SDN can be considered as an unfavorable structure for delay-sensitive services because a centralized architecture is needed to communicate with many nodes and provide processing power. Therefore, in the case of emergency V2X communications, delay-related control functions require a tree supporting structure. For such a scenario, the architecture of the network processing the vehicle information is a major variable affecting delay. Because it is difficult to meet the desired level of delay sensitivity with a typical fully centralized SDN structure, research on the optimal size of an SDN for processing information is needed. This study examined the SDN architecture considering the V2X emergency delay requirements of a 5G network in the worst-case scenario and performed a system-level simulation on the speed of the car, radius, and cell tier to derive a range of cells for information transfer in SDN network. In the simulation, because 5G provides a sufficiently high data rate, the information for neighboring vehicle support to the car was assumed to be without errors. Furthermore, the 5G small cell was assumed to have a cell radius of 50-100 m, and the maximum speed of the vehicle was considered to be 30-200 km/h in order to examine the network architecture to minimize the delay.
