This Study aims to examine the differences in stress arising from clinical fieldwork of some of the students of occupational therapy department in accordance with the DISC behavioral style and the differences in the coping strategy. It is to provide basic data for the presentation of means of coping with stress that can occur at the time of clinical fieldwork in accordance with the behavioral styles of the students. As the results of the study, it was found that there are differences in the detailed items of clinical fieldwork stress in accordance with the DISC behavioral styles and differences in the strategy for copying with stress in accordance with the DISC behavioral styles. Therefore, there is a need to develop manual for fieldwork instructions and consultations in order for the students of occupational therapy department to cope with the clinical fieldwork stress at the time of clinical fieldwork by considering the behavioral styles of the students through additional researches in the future on the basis of aforementioned results of the study.

There have been several reports about abdominal pain due to discitis in children or thoracic disc herniation. However, none of them could verify causal relationship between disc disease and abdominal pain clearly. The authors report a patient with discogenic abdominal pain who had disc degeneration at lower lumbar level without definite protrusion or any evidence of inflammation. We could reproduce the abdominal pain by using discography. The patient was treated by percutaneous disc decompression successfully.

Discal cyst is an intraspinal cyst with a distinct communication with the corresponding intervertebral disc. It is a rare condition and could present with radiculopathy similar to that caused by lumbar disc herniation. We present a patient with a large discal cyst in the ventrolateral epidural space of the $5^{th}$ lumbar vertebral (L5) level that communicated with the adjacent $4^{th}$ lumbar and $5^{th}$ lumbar intervertebral disc, causing L5 radiculopathy. We alleviated the radiating pain with selective transforaminal epidural blocks.

A constant torque dynamometer with associated instrumentation and control functions for the development of friction materials for automotive-type disc brakes, has been developed. Full scale disc pads are subject to a series of intermittent brake applications at a constant rotational speed of the brake disc and constant braking power. This paper gives a description of the dynamometer and an example of results obtained.

In this paper, we evaluated error correction performance and recording density of an optical disc system. The performance of Low-Density Parity Check code (LDPC) is compared to the HD-DVD (BD) ECC. The recording density of optical disc can be increased by reducing the redundancy of the user data. Moreover, since the correction capability of LDPC with decreased redundancy is better than that of BD, the recording density can also be increased by reducing the mark length of the data on the disc surface.

Korean high speed train (KHST) has adopted a combined electric/ mechanic (friction) braking system. Electric brakes are consist of rheostatic brake, regenerative brake and eddy current brake and mechanical brakes are composed of disc brake, wheel disc brake and tread brake. In this paper, we introduce the braking performance test and the measuring method of mechanical brake. And disc brake performance has been reviewed by the experimental method. The on-line test of KHST has been carried out up to 260 km/h and proved that the disc braking capacity of KHST is sufficient.

This paper is on the discrete model reduction method over disc-type analytic domains. We define hankel singular value over the disc that is mapped by standard bilinear mapping. And the generalized singular perturbation approximation and the direct truncation are generalized to GSPA and DT over a disc. Furthermore, it is shown that the reduced order model over a smaller domaing has a smaller .inf.-norm error bound. And the poposed reduction method is used to obtain the regional pole placement property.

This paper describes the application of a coupled finite element-boundary element method (FE-BEM) to obtain the steady-state response of a piezoelectric transducer. The particular structure considered is a PZT4 disc-typed projector. The projector is three-dimensionally simulated to transduce applied electric charge on axial surfaces of the piezoelectric disc to acoustic pressure in air or in water. The directivity pattern of the acoustic field formed from the projected sound pressure is also simulated. And the displacement of the disc caused by the externally applied electric charge is shown in temporal motion. The coupled FE-BE method is described in detail.
