A high speed feeding type laser cutting UC is developed for the precise cutting of sheet metal. The M/C is a flying optics type one with specified functions of movability and strength in order to increase workability. The gantry frame should be moved with a certain velocity within a relatively short time for the proper cutting of object materials. The gantry is actuated by rack and pinion. In this paper, modal and structural analysis for a laser culling M/C, is carried out in development of the machine The machine is modeled by placing proper shell and solid finite elements and fictitious mass properties to represent the real one.

To explore the seafloor, an observation instrument should be laid there for a long time and it should be again withdrawn. This system must be designed low power consumption model because it operates for a long period, but because power control don't execute or simply control algorithm executes, power efficiency is low. Hereupon, a power control algorithm for retrieval system using the ultrasonic communication that was improved its controllability and movability was presented in this paper. Likewise, the logicality of control algorithm and remote control system were ascertained by experiments.

To secure abyssal resources, submarine environment should be firstly explored. On that occasion, the withdrawal of the instrument is of importance and the submarine ultrasonic wave should be stably identified regardless submarine environment and passive factor. In the existing control methods, the control informations, received from an observation instrument, are identified used by hardware and repeatedly compared with standard information. Hereupon, a marine observation instrument remote control system using the combination of FSK and ASK that was improved its controllability and movability was presented in this paper. Likewise, the logicality of control algorithm and remote control system were ascertained by experiments.

FRT design aims at high-tech vehicles of high efficiency and cleanness, it must materialize the meaning and role as new added value by applying car design aesthetics of a new future-oriented concept. In addition, different from ordinary vehicle design, FRT involves invisible factors such as pleasantness, safety, accessibility, controllability, movability, conveniency, culture, identity, brand image and fashionableness. Because FRT vehicles are transportation means used by various groups of people, they must be approached with the barrier-free design concept. Therefore, in order to enhance the potential of future transportation culture emphasizing creativity based on diversity, it is important to establish core design factors that create new added values and to apply new concepts to their roles.

Although Gyeonggi-do is the core area which has a quarter of the population of Korea, it has poor railway network and then it have got serious traffic problem. So in this paper, it is introduced the improving methods of railways on Gyeonggi-do. In first, it was showed a fast and effective railway route implementation according to the characteristics with the similar population but the 17 times bigger area than that of Seoul. And it was explained multipurpose using method of the railways of Gyeonggi-do whit subway, commuter, express and high speed train etc. Finally unlike Seoul subway focusing on approachability, it was proposed 'express train paradigm' focusing on implementing the high movability which railways of Gyeonggi-do must have. So with 'Bundang-line' metropolitan railway, the case study in applying to southern metropolitan area with those suggestion was showed.

Street is an important factor that street quality determines urban quality as the space of the high public nature in city. The research method considering sequence landscape is important because it is considered that the impression of such a street is formed by the wholeness of consecutive landscape and experience in moving street. Therefore, this study are pursued to structure the analysis of psychological evaluation and environmental attribute base on the physical characteristics of sequence landscape to supply the basic materials for seeking the national direction as qualitative improvement of urban street space and the attractive urban street space. Then the results are as follows. It is shown that the psychological evaluation structure of sequence landscape is evaluated by ornamental nature, intimacy, orderliness, openness and movability and that of environmental attributes is evaluated by four factors such as activity, intimacy, spatial attribute and openness.

In this paper, the origin, development and features of a Korean folding stool are studied. A folding stool is a piece of collapsible seating furniture with its legs crossed in the form of the letter "X" and no back attached. In China, the folding stool was introduced from the West around the second century A.D. The folding stool of Korea was influenced by that of China. It is known from the records that the king used the folding stool from the Three Kingdom period. During the Koryo period, Chosun period and the modern period, the folding stool was used to show the authority of the king and nobleman. The folding stool was also used at outside places such as a hunting ground, a ceremonial walk, a battlefield, a garden etc. due to its portableness. Buddha worship policy of Koryo period supported the usage of the folding stool for shanding (禪定) by ascetics of Buddhist temple, or aristocrats. In a contemporary period, the folding stool is continuously produced and used as one kind of a folding chair due to its functionality, movability, storability and efficient space utilization. This research will serve as a momentum to investigate the origin and development of the East Asian seating furniture culture, and contribute to the further study and manufacturing of Korean seating furniture.

In case of segmental injury of trachea, the primary repair is very difficult, because the trachea is fixed in place without movability from the surrounding tissue. In addition to special anatomical situation of trachea, any ideal artificial prosthesis for tracheal replacement is not still appeared. Many authors proposed several procedures for the tracheal repair, but satisfactory results were few. Among the proposed procedures end to end anastomosis of trachea was noted superior when both ends of trachea could be approximated by mobilization of upper and lower injured trachea. The author's experiment was designed to determine the effect about decreased tension on trachea when the hyoid bone was released downward from the surrounding muscular structures. The experimental dogs were divided into two groups, suprahyoid releasing group (SH R) and control group of intact hyoid. SH R group was subdivided into two groups accord ing to he degree of tension. The experimental results were as follow; 1. SH R group: In view of X-ray, the distance between the angle of mandible and the displaced hyoid bone was lengthened downward. And it's range was from 1.3cm (38%) minimally to 2.7cm(108%) maximally. 2. Control group: The distance between the angle of mandible and hyoid was same in both pre and postoperation. As the result of this experiment study, the suprahyoid release technique seems to be the efficient method that enable of release the trachea maximally. And it should be expected that the SH R technique is applicable clinically.

Rapid increase of aging population and progressed migration from rural areas to urban areas have caused deficit of bus routes in local cities. This increasing burden of operation deficit affects the movement strategy of the transportation vulnerable who are using buses. Along with dramatically increased aging in Korea, there is an urgent need to implement a new method which can guarantee mobility rights of public transportation especially for the elderly. This study focuses on the case of Demand Responsive Transit(DRT) system that has been operating in America, Europe, Japan, etc. Kimhae(Sangdong-myeon and Saengnim-myeon) is selected as a study area. This study investigated the possibility of adopting DRT system on the perspectives of the consumer and provider by the analysis of traffic condition such as the number of transportation vehicles, present bus service and regulation and conduct of questionnaire survey which includes present bus service and DRT system and so on. In conclusion, DRT system in Kimhae city will reduce transport cost, increase affordability through the betterment of service level and secure mobility rights for the transportation vulnerable.
