This study is to understand the emotional tendency through out the history of architecture and interior design. In this process, a broad range of analysis of the period between Romanticism and Post Modernism will be done to collect historical data and the influence of the social situation. A thorough review and close examination of the 90's architectural trend will reveal the foundation of the concept behind GSD not just as the post-structuralism as a value system of digitalism but also makes easy to understand GSD in space design. In particular, the study will reveal how the ideas of post-structural philosophy has effected the formation of its movement as well as its influence to become the theoretical nutrition for digital architecture. The result of the study will be used as the valuable reference to define 'Emotional Design'(So call 'Gam-Sung Design = GSD) and become the foundation for further investigation on GSD space design in the near future.

The major movement block of the containers have range between apron and designation points on yard in container terminal. The yard tractor operated by human takes charge of its movement in conventional container terminal. In automated container terminal, AGV(Automated Guided Vehicle) has charge of the yard tractor's role and the navigation path is ordered from upper level control system. The automated container terminal facilities must have the docking system to guide landing line to have high speed travelling and precision positioning. The general method for docking system uses the vision system with CCD camera, infra red, and laser. This paper describes the detection of AGV's position and orientation using laser slit beam to develop docking system.

Direction-of-motion stereotypes between ON/OFF controls were tested using a paper-and-pencil test and interview method. One hundred and forty eight subjects of both genders and from a wide range of ages were asked to indicate the control movement they would make to turn on the light. Stereotypes were obtained for nine types of ON/OFF controls in two different planes. The results show that stereotype for left-right power switches is right for on, and stereotype for up-down switches is up. And, a strong stereotype was found in the case of left-right switches than up-down switches. Some stereotypes are significantly different between genders and age groups. These findings identified in this study can be used to design the ON/OFF switches of the facilities and equipments.

Experimental studies were carried out to investigate water diffusion in unsaturated compacted bentonite for a landfill of hazardous wastes. Water content distributions were measured and water diffusion coefficients were determined when the dry densities of compacted bentonite were in the range of 1.4 - 1.8 g/㎤. Resaturation times were also calculated to analyze the ability of the compacted bentonite to retard water movement. The results obtained were as follows: Diffusion model described properly the water migration in unsaturated compacted bentonite. Water diffusion coefficients ranged from 4.30$\times$10$^{-6}$ $\textrm{cm}^2$/sec to 1.93$\times$10$^{-6}$ $\textrm{cm}^2$/sec, and decreased with increasing the dry density. The dry density of compacted bentonite was found to be an important factor to control the resaturation time by water. This study suggests that the domestic compacted bentonite should be a good barrier material against water movement in a landfill of hazardous wastes.

This research develops a low-cost and high accurate kinematic calibration method for a parallel typed machining center tool. A planar table is used for a mechanical fixture restricting the platform to place at the constrained pose and a low-cost and high accurate digital indicator is employed for a device checking if the constrained movement is satisfied within the established range. The kinematic parameters calibrated with respect to a single plane aren't influenced from the misalignment of the plane. A parameter observability is successfully obtained even through one planar constraint, which guarantees that the kinematic parameters is estimated by minimizing the cost function.

As the accuracy of manufactured goods needed high accuracy processing has made the efficiency of NC and measurement technology development, the innovation of machine tools has influence the development of the semi-conductor and optical technology. The movement errors can be expressed in terms of yaw, roll an pitch etc. In the case of expanding the error range, static, dynamic and servo gain errors can be included. Machining center might have twenty-one movement errs including three types of joint errors. Those errors have been measured on the condition of just loading of standard table. Regarding these measuring methods, the mechanical compliance of the structure has not been considered. In this paper, therefor, the influences of the additional load on the positioning accuracy are investigated. The results and the techniques proposed in this study can be considered very effective and useful to compensate more correctly the positioning motion.

SRMD system which protects MBT from the threats in a short range is composed of 2 radars, 2 IRTs 1 CCU and 2 countermeasures. To analyze the performance of this system, there is a need to make the model of MBT on which this system is loaded. In this paper, a method of MBT movement modeling is proposed to fulfill the above need. The methods of the coordinate system transformation among the components and the modeling of a hull's traveling and a turret's turning are proposed. The method of the modeling of a pose variation caused by the vibrations is proposed and the results of the modeling are presented.

Objective : The purpose of this study is to evaluate the korean medical treatment for compressive neuropathy of radial nerve, especially chuna treatment of cervical vertebrae. Methods : Two patients were treated with acupuncture and moxibustion, herbal medication, chuna treatment on cervical vertebrae. To evaluate the wrist drop and numbness of hand, Coding Result of arbitrary values and manual muscle test(MMT), visual analogue scale(VAS) were used. Results : After 2 weeks-treatment(in case 1) & 5 weeks-treatment(in case 2), the movement and power of wrist were restored to nearly normal range, also the numbness of hands was removed. All cases show the improvement in the movement of wrist and the numbness of hands. Conclusions : Korean medical treatment including cervical manual therapy as chuna treatment is remarkably effective for radial nerve palsy. But further studies are required to concretely prove the effectiveness of chuna treatment on central vertebrae for peripheral neuropathy.

Soil contamination with petroleum oil around a military army was investigated. It showed that soils of a riverside highland, an entrance of the military army, and nearby roads were contaminated with total petroleum hydrocarbons (TPH) released from the military army to the depth of approximately 2 m. The measured concentrations were as high as 15,277 mg/kg. A wide range of soil in the riverside highland was contaminated by the movement of oil to the surface soil, which occurred with the vertical movement of groundwater table caused by the change of river water level and groundwater level. Spilled petroleum oil components were released into Wonju Stream by the increase of hydraulic conductivity and the groundwater flow.

This paper studies the observability of calibration system with a constraint movement by a constraint operator. The calibration system with the constraint movement need only simple sensing device to check whether the constraint movements are completed within an established range. However, it yields the concern about the poor parameter observability due to the constraint movements. This paper uses the QR-decomposition to find the optimal calibration configurations maximizing the linear independence of rows of a observation matrix. The number of identifiable parameters are examined by the rank of the observation matrix, which represents the parameter observability. The method is applied to a parallel typed machining center and the calibration results are presented. These results verify that the calibration system with low-cost indicators and simple planar table is accurate as well as reliable.
