지능형 교통 시스템(ITS)은 정보 처리, 통신, 제어, 전자 등 다양한 첨단 기술들로 구성되며 이러한 기술들을 교통 시스템에 접목함으로써 더욱 안전한 인명 구조 및 시간과 경비 절감을 더욱 효율적으로 추구하게 된다. 국가 ITS 아키텍쳐는 지능형 교통 시스템을 설계, 정의, 통합하기 위한 공통적 프레임워크를 제공하며 대부분의 ITS 과제들은 모든 표준화 작업을 총괄하는 기준 프레임워크인 국가 아키텍쳐에 따라 설계 및 구현되고 있다. 최근 소프트웨어 기술이 급속히 개선되고 안정화됨에 따라 미리 개발된 강력한 ITS 기술도 재 사용할 필요성이 있다. 컴포넌트와 개방형 인터페이스에 기반한 ITS 표준화는 현재 ITS 기술의 재사용성 문제를 해결하는 방법이 된다. 본 논문은 국가 ITS 아키텍쳐에 기반한 ITS 컴포넌트를 설계하고 구현하는 방법에 중점을 두고 있으며 첨단교통정보제공 시스템(ATIS) 컴포넌트 개발 과정에서 실제 UML을 이용한 설계와 분석이 수행되었다. 이 UML 방법은 새로 개발되는 ITS 컴포넌트를 위한 표준화된 모델을 제공할 것으로 기대된다.

The purpose of this study was to provide basic data for development of environmental design technology for greenhouses constructed in reclaimed lands. We analyzed the climatic conditions around seven major reclaimed land areas in Korea, which have a plan to install advanced horticultural complexes. The characteristics of heating load through the thermal environment measurement of the greenhouse in Saemangeum were analyzed. The part to be applied to the environmental design of the greenhouses in reclaimed lands were reviewed. The overall heat transfer coefficient of the experimental greenhouse with the aluminum screen and multi-layer thermal curtain averaged $3.79W/m^2^{\circ}C$. It represents a 44 % heat savings rate compared with plastic greenhouses with a single covering, which was significantly lower than that of the common greenhouses with 2-layer thermal curtains. This is because the experimental greenhouse was installed on reclaimed land and wind was stronger than the inland area. Among the total heating load, the transmission heat loss accounted for 96.4~99.9 %, and the infiltration loss and the ground heat exchange were low. Therefore, it is necessary to take countermeasures to minimize the transmission heat loss for greenhouses constructed in reclaimed lands. As the reclaimed land is located on the seaside, the wind is stronger than the inland area, and the fog is frequent. Especially, Saemangeum area has 2.6 times stronger wind speed and 3.4 times longer fog duration than the inland area. In designing the heating systems for greenhouses in reclaimed lands, it is considered that the maximum heating load should be calculated by applying the wind coefficient larger than the inland area. It is reasonable to estimate the operation cost of the heating system by applying the adjustment factor 10 % larger than the average in calculating the seasonal heating load.

직접회로의 직접도 증가로 인해서 신경망을 칩으로 구현하려는 시도가 이뤄지고 있고 현재 뉴런을 모방하는 칩이 나와있는 상황이다. 하지만 이런 시도는 신경 자체를 모방하려는 것으로 아직 직접회로의 직접도를 볼 때 그런 시도가 의도하는 궁극적인 목표인 대규모의 신경망을 구현하기엔 부적합하다. 차라리 신경망의 단위를 이루는 뉴런을 구현하는 것보다는 신경망을 모방하는 시스템의 모방이 보다 적절하다. 여러 신경망이나 패턴분류 등의 신호처리에서 공통으로 필요로 하는 연산이 있다. 바로 대량의 신호를 곱하고 더 하고 LUT를 읽는 연산이다. 이 연산은 신경망에서 한 층의 각 노드들로부터 그에 따른 다음 층으로의 연결들 각각을 곱해서 더해주고 시그모이드 값을 발생시키는 작업과 동일하며, 반복적이고 많은 계산량을 요구하므로 이 부분을 고속 하드웨어로 만들 경우 시스템 전체의 속도 증가를 기대할 수 있다. 그래서 여기서는 뉴런이 아닌 신경망을 구현하는데 그것은 신경망뿐만 아닌 다른 많은 응용을 기대할 수 있는 공통적 연산부분이다. 이 연산을 앞으로 논의할 비트 분리 연산구조 방식으로 처리함으로써 실시간 병렬처리에 응용할 수 있도록 하였다.

Hydrogen is a fuel of fuel cell system, which has powerful explosion possibility. Hence, the fuel cell system needs safety evaluation to prevent risk of hydrogen leakage. We use a actual size chamber of a common fuel cell module to analyze hydrogen. Hydrogen injection holes are located in lower part of the chamber in order to simulated hydrogen leakage. The hydrogen sensor can detect range of 0${\sim}$4%. Since the hydrogen gas, of which leaked amount is controled by MFC, are injected at the bottom holes, the transient sensor signals are measured. At a condition of 10cc/s of hydrogen leakage, the sensor detects hydrogen leakage after 22sec and there is also several seconds of time delay depending on the position of the sensor. This experimental data can be applied for the design of the hydrogen detection system and ventilation system of a residential fuel cell system.

The purpose of this study is to research development process of commedia dell'arte and Korean masque that have similar figure, grasp similarity and difference and find the meaning of masque and costume in both theatrical arts. Italian commedia dell'arte and Korean masque are performed by wearing standardized mask and costume depending on the role. As common points, first, the characters have unique names and possess unique features of character, costumes, masks and playing styles. Through the feature, the audiences can understand role of actor and the actors can devote themselves to their role by wearing masks and costumes. Second, although background plays an important role in commedia dell'arte, the role of costume is more important. Because masque speaks for poverties of general people indirectly, the costumes of general people were used as they are. As different point, first, most of Korean masks cover entire face, restricting speech of actor but masks of commedia dell'arte cover only upper part of face and expos mouth and chin of actor, enabling actors to express various emotions depending on the character. Second, priority is given to personality of actor and origin area and current silhouette, material and color that changed by century is reflected in the costume of commedia dell'arte but silhouette, material and color of the Age of Joseon Dynasty were adopted in Korean masque.

The purpose of this study is to clarify the different types of cooperation between the textile industries and the artists at the beginning of the 20th century in relation to the social background which motivated the artists. Therefore, this study tries to analyse the interactions between the cooperation and the movement of social reform of the period and describe the various phase of artistic expression as a result of artists' view point of the society. The results are as follows; 1. There are two different standpoints toward the cooperation. The one conceives the different role of artists in relation to society and the other tries to enlarge the field of expression as an artistic challenge. 2. The different standpoint engenders significant diversity in its development, result and decline. 3. The raise of new artist group "designer" who reconciles the art and the industry as vocation diminishes the need of direct participations of artists. 4. The spirit of the time has changed and emphasised more the conceptual part of the art than the properties of matter. It provides less favorable condition for the cooperation. The cooperation between the art and the industry is a significant resource of the textile and clothing design. The interaction is not limited to visual effect but partakes in the solutions of the common artistic or social problems. problems.

The typical design of automotive driveshafts generally utilizes Constant Velocity(CV) joints as a solution to NVH. CV joints are an integral part of vehicles and significantly affect steering, suspension, and vehicle vibration comfort levels. Thus, CV joints have been favored over universal joints due to the constant velocity torque transfer and plunging capability. Although CV joints are common in vehicle applications, current research works on modeling CV joint friction and assumes constant empirical friction coefficient values. However, such models are long known to be inaccurate, especially under dynamic conditions, which is the case for CV joints. In this paper, an instrumented advanced CV joint friction apparatus was developed to measure the internal friction behavior of CV joints using actual tripod-type joint assemblies. The setup is capable of measuring key performance of friction under different realistic operating conditions of oscillatory speeds, torque and joint installation angles. The apparatus incorporates a custom-installed triaxial force sensor inside of the joint to measure the internal CV joint forces(including friction). Using the designed test setup, the intrinsic interfacial parameters of CV joints were investigated in order to understand their contact and friction mechanisms. The results provide a better understanding of CV joint friction characteristics in developing improved automotive driveshafts.
