Since tram has the advantages to reduce construction cost of infrastructure, to improve accessibility of passengers, and to offer visual pleasures, nowadays, it is one of light rails attracting public attention. Tram can be classified into two groups, one is a conventional steel-wheeled type, and the other is a rubber-tired type (bi-modal tram). The bi-modal tram propelled by the serial CNG hybrid propulsion unit has been developing since 2003 in Korea, which can realize both scheduled operation of railway and route flexibility of bus. Because the bimodal will be operated on both railway mode and bus mode, however, specific criteria and regulations for its design, certification, construction, operation and maintenance have not been determined definitely yet. In consideration of mobility enhancement for the old and the handicapped, motor vehicle safety standard and urban transit (railway vehicle) safety standard, several design specifications were proposed for car body and interiors of the bimodal tram vehicle. The design specifications proposed in this paper can be expected to promote passengers' comfort and safety, operation efficiency of the bimodal tram.

The purpose of this study is to present the dwelling space by attaching or inserting the mobile space unit to the fixed building by providing the temporary dwelling space for those suffering from flood disaster, natural disaster or solitary old people or the space and program that the completed building in the city can not provide such as temporary events in the bridge, passage space, walking space for the handicapped, stores located between street blocks, and plaza. Therefore, this study was intended to investigate temporary dwelling space through the composition of space and the experiment of the applicability of the program through the methods of movement, folding, module, expansion and evolution of mobile space. An attempt was made to apply the concept of ‘mobile space’ to the dwelling space not only with a focus on the freedom of variable and changeable physical movement but also with a focus on the existence of the nomad and the way of thinking that bleaks away from a given value system and code, creates a new value and continues to move to a new domain. This study attempted to analyze how the concept of ‘mobile space’ has been developed in what form and method they have been applied and interpreted in the historical background. It attempted to resolve the concepts of movement and mobility through the experiment so that they might apply to the space of contemporary city. This study attempted to experiment this possibility using the mobile space unit and apply it.

The aim of this paper is to examine the demographic characteristics and the attitude about marriage and the policy of the unmarried male farmers. The contents of research are two folds: 1) Analyze the marriage related demographic statistics of rural area using the data from Korea Statistical Information System and marriage statistics in 2007, 2) survey analyses of the attitude toward marriage, perception and needs of international marriage, and related policies from data of 170 unmarried male farmers. The results are as follows: first, the marriage rates among over 15 years old of the rural area is 78.2% for men while 1.8% for 20${\sim}$24 age group and 9.3% for 25${\sim}$29 age group. The marriage rates in this area are varied by region especially low in Kyunggido & Jejudo. Second, the portion of international marriages of Korean male farmers with foreign partner are 11% among all international marriages of Korean males. There are high rates of male farmers' international marriage in Junranamdo and Kyungsangbukdo which are characterized by low level of urbanization, low inter-city mobility, low rates of age group of under 15 years and high portion of over age 65. Finally, the survey results showed that 83% of the sample lived with their parents; event though 80% of farmers think marriage is necessary, 60% had no plan of marriage because of difficulties to meet marriage partners and of lacking economic resources; they showed a negative perception toward the handicapped, foreigners, Afro-Americans, Westerners and divorcees as a marriage partner; they also showed negative recognition to international marriage because of observed problems of neighboring international marriage couples and concerns of cultural differences; they pointed out that the government's concern about improving quality of the environment of the rural area and reforming the international marriage aid law was the most necessary. The discussion and the future research directions were added.

The purpose of this study was to provide information on driving characteristics in persons with spinal cord injury through basic statistic analysis of the survey results. The survey was administered to 44 drivers with spinal cord injury. The subjects' general, neurologic and driving characteristics were analyzed, as well as the degree of difficulty in using their vehicles between tetraplegia and paraplegia. The results were as follows: thirty-five (79.6%) of forty-four respondents was men. The average age was 35.0 years old and the age at the time of injury was 29.0 years old. Their neurologic characteristics were tetraplegics 12 (27.3%) and paraplegics 32 (72.2%). Among complete lesions, the highest level those who could drive independently was C7. All the vehicles were equipped with special devices, including "power steering", "automatic transmission" and "hand controls". The vehicles for cervical cord injury were equipped with "grip bars" as well as for the degree of difficulty in using their vehicles, all the subjects felt that "moving the wheelchair in and out of their vehicles" was too difficult for them to do. We suggest that the driver training should be an essential part of the rehabilitation program for patients with spinal cord injuries to maximize their mobility in the community. This training seems to be essential in order to modify the standards of the Handicapped Drivers Ability Test and to aid the driver rehabilitation program in the health insurance payment system. Also, the driver rehabilitation training program should include instruction in that moving wheelchairs in and out of vehicles.

Today, the elderly is increasing gradually in the Republic of Korea society and this problem will be more serious in the near future. Therefore, engineering support for aged people is required. We are establishing a new field of healthcare engineering for elderly people and aiming to support for aged people and disabled people using adaptive control and instrument technology. In this paper, the goal is to implement the shared control of a robot mobility aid for the elderly. As using this type of assistive technology to be useful by its intended user community, it supports elderly people and handicapped people to live independently in their private homes. The interface transforms the force applied by the user into the robot's motion. Devices like buttons, joysticks, and levers already exist for relaying user input; however, they require hand displacement that would loosen or otherwise release the user's hold. Such interfaces make operation very difficult and potentially unsafe. Therefore, we propose a shared control system. It's safe more than joysticks and buttons. The shared control is a means of registering the user's intention through physical interaction. It's an important component in the development of robotic elderly assistant. The concept of shared control describes a system which is two or more independent control systems. We are using that the three component blocks consist of pressure sensor (flexible force sensor), circuit of measurement and transfer function. Experimental trials of this paper have been tested at the indoor environment. The robot is able to know the user intended direction through haptic device were logged along with the robot's force sensor.

The purpose of this study is to illustrate the design of safety suits based on energy-harvesting technology, particularly targeting street cleaners who must work at night with high mobility. The design focuses on applying lightweight energy-harvesting tools and illuminant into the wear. The design development reflects feedback from testers collected via survey constituting a key methodology. The development process has two main stages. Each stage uses a process of design prototyping, internal examination, test sampling, test wearing, and wearers' feedback via survey that consists of questions on visibility, wearing convenience, and washability. The first stage results show the design of safety suits with energy-harvested LED illuminant inserted and the survey results collected from street cleaners dressed in 4 sample and 80 actual suits in total. Improved based on the first-stage survey results, the second stage designs the suits with detachable energy-harvested EL tape. From these 5 sample and 30 actual second-stage suits, the additional survey indicates that this second-stage design facilitates more visibility and convenience in washing and wearing than the first-stage design. Accordingly, one can expect that this new design can apply not only to safety suits for night workers but also to handicapped or outdoor sportswear applications in the future.

경제적 효율성의 추구를 최고의 목표로 하는 자본주의 경제체제에서 생산과 소비의 과정은 가능한 한 '효율적'으로 수행할 필요성이 제기되며 이러한 과정에서 통행에 소요되는 시간은 일종의 '낭비'일 수 밖에 없다. 따라서 통행은 가능한 한 빠른 시간 내에 이루어져야 하며 이러한 조건을 충족시키기 위하여 자가용 등 차량에 의한 통행이 선호될 수 밖에 없다. 그러나 차량통행의 증가 특히 자가용 통행의 증가와 이에 따른 차량위주의 도시교통체계는 여러가지 형태의 사회적 문제를 유발하며 특히 차량통행의 증가에 따른 지역사회의 황폐화, 계층간 접근성 및 이동성의 차등화 등의 측면에서 상당히 부정적인 영향을 유발하고 있는 실정임에도 불구하고 우리 나라에서 이에 대한 체계적인 연구는 거의 전무한 실정이다. 이러한 배경에서 본 연구는 우리사회에서 교통으로 인하여 발생할 수 있는 사회적 영향들을 체계적으로 분석하기 위한 기초작업의 일환으로 교통으로 인하여 유발되는 사회적 영향들의 형태와 이에 따른 문제점들을 제기하고 이러한 문제들을 해결하기 위한 앞으로의 연구 방향을 제시하는 데 그 목적이 있다.

설유착증(tongue-tie)은 비정상적으로 짧은 설소대로 인하여 혀의 움직임이 제한되는 것을 의미한다. 영유아에서 심한 설유착증은 수유곤란을 야기하기도 하고, 증상이 지속적으로 존재할 때는 혀의 운동범위가 제한되어 발음문제를 야기할 수 있다. 또한 비정상적인 혀의 위치로 인해 여러 가지 교정적인 문제를 초래 할 뿐만 아니라, 기능적, 사회적 장애요소로 작용할 수도 있다. 설유착증의 치료방법으로는 관찰, 언어치료, 단순절개술 그리고 절제술 등이 있는데, 수술시기에 대한 논란은 있지만 정도가 심하여 장기간 언어장애가 지속되거나 교정적인 문제를 야기 할 것으로 판단되는 경우 조기수술이 권장되고 있다. 진정요법은 조기치료가 필요한 나이가 어리고 비협조적인 환아들이나, 신체적, 정신적 이유로 통상적 인 치과진료에 어려움이 있는 환아들에게 효과적으로 사용될 수 있는 방법이다. 본 증례는 설유착증으로 수술이 필요하나 협조전단계인 환아를 대상으로 경구투여를 이용한 진정요법으로 소대절제술을 시행하여 양호한 결과를 얻었기에 이를 보고하는 바이다.
