The treatment of anterior disc displacement without reduction patients needs speicific treatment methods different from other Craniomandibular Disorders. Those are manual manipulation, anterior repositioning splint; ARS and step-back. It is well known that the use of Anterior Repositioning Splint is effective on relief of TMJ symptom. But the side effect of long- term ARS wearing, which is irreversible posterior open bite induction, has made many clinicians avoid ARS treatment. This report introduces a clinical case recently proven part- time wearing ARS method for treatment of Disc Displacement without reduction patient' that can reduce side effects with good efficacy. But now clinical statistical studies and basical histophysiological studies are more needed.

The effective dose and the organ absorbed dose, which are given to a breast in the cases of using and not using the bismuth breast protection shield for the protection of a breast with the coronary artery CT angiography, have been measured and compared for the manual exposure control (MEC)and the automatic exposure control (AEC). In the cases of using and not using the bismuth breast protection shield, it has been found that the measured dose shows the reduction of about 23 to 26% for the MEC and about 22 to 25% for the AEC when the shield is used compared to the case of not using it. By comparing the shield and non-shield cases for the AEC and the MEC, it can be said that the value measured by carrying out the scanning process with the AEC mode has decreased by about 24 to 30% compared to the case of applying the MEC mode. Such a result shows that it is recommended to use the AEC mode for the reduction of the patient's exposure dose during the CT examination.

Traction is the treatment of choice for a small nuclear protrusion. The nucleus is soft and can be influenced by suction. Traction provides a method of improving on recumbency-the only effective treatment before traction was devised. The intention is to achieve rapid reduction by distraction the joint surfaces mechanically-a positive purpose-instead of merely avoiding the compression of the upright posture by putting the patient to bed and leaving him there. Recumbency, usually successful in the end, wastes an endless amount of the patient's time and money. Traction carries the further advantage of enabling the patient to be up and about, attending to his bussiness, during treatment. Traction brings the joint surfaces much farther apart than just lying in bed, a greater centripetal force acts on the protruded part of the nucleus. Traction has three beneficial effects; 1. Suction : a sub-atmospheric pressure induces a centripetal effect on the contents. 2. Distraction : increases the distance between the articular edges. X -rays have shown an increase in width of the joint of 2.5 mm. 3. Ligamentous tightening : the posterior longitudinal ligament tightens which then exerts centipetal force on a central protrusion.

The purpose of this study is to establish PM-10 management manual for developing large scale sites by assessing the status of PM-10 reduction at ongoing large scale development sites. After analyzing the meteorological conditions and air quality characteristics of Sihwa MTV development site, ISCST3 (Industrial Source Complex Short Term Model 3) was implemented to predict PM-10 generation. The outcomes of ISCST3 modelling were utilized for verification of site survey data. As a result of applying air pollution modeling, the diffusion rate of PM-10 decreases according as the wind speed decreases. And the emission rate of PM-10 increase is linear to the concentration of PM-10. The reduction target of PM-10 can be derived quantitatively from the difference between the forecasted emission rate and the permissible emission limit of PM-10. The assessment of PM-10 characteristics which is deduced from ISCST3 and site survey can be practically applied to accomplish environmentally acceptable air quality manual for large scale development sites.

The manual was proposed for individual role, according to the stages of forest fire suppression at forest fire occurrence site, for forest fire crew who has a responsibility of national forest office. The scopes of this manual are (1) apply to initial attack before arriving helicopter, (2) apply to ground fire fighting support with air attack, (3) apply to mop-up after withdraw air attack, (4) apply to night suppression when air attack is impossible. This manual is arranged for incident commander or ground fire fighter duties from the 1st stage of acceptance of forest fire to the 10th stage of withdraw of helicopter. This was developed for the purpose of every awareness of the crews and therefore of fire reduction of damage of lives, properties and forest through systematic and rapid response to forest fire.

Objectives : The aim of this study was to observe the effect of Bong Chuna manual therapy(BCMT) and acupuncture on the Turtle Neck Syndrome(TNS) by the changes of radiological findings and symptoms. Methods : Total twenty-eight patients diagnosed as TNS were evaluated. Twenty patients in experimental group were treated by the combination of BCMT and acupuncture, eight patients in control group were treated by acupuncture only. We measured VAS(Visual analogue scale) as pain intensity and Neck Pain and Disability Scale(NDI) at pre- and post-treatment. Also the four line Cobb's method and Jochumsen method were assessed for evaluating the radiographical changes, additionally we used 'two line method'. Results : VAS score showed statistically significant reduction in pain intensity in both experimental group and control group after 8 weeks treatment, $-44.05{\pm}14.91$ vs $-23.75{\pm}14.08$ respectively. Also NDI score presented $-11.40{\pm}8.63$ reduction in experimental group, and it was significant statistically, however not in control group, $-8.63{\pm}9.84$ reduction after 8weeks treatment. In radiological findings, the four line Cobb's method, Jochumsen method and two line method were reduced after 8weeks treatment, $-9.30{\pm}10.33$, $-0.65{\pm}1.72$ and $-14.35{\pm}5.68$ in experimental group respectively, $-0.75{\pm}1.91$, $-0.25{\pm}0.71$ and $0.38{\pm}2.20$ in control group respectively. However they were statistical significance only in the four line Cobb's method and two line method in both group. Conclusions : Combination treatment of CMT and acupuncture showed better effect on pain reduction, VAS score and the correction of neck anteversion than acupuncture only in TNS. Two line method seems valuable for evaluating the improvement of radiographical changes in TNS.

The extremely strong competition among the world automobile industries has introduced the concept of PLM in the total production activities, one of whose major components is VM(Virtual Manufacturing). If the production lines are equipped with robots, the application of OLP in the virtual space is fully mature. However, in the point of the investment's and the maintenance's view, there are always some activities, which can not be automated: for example, typically the manual welding for prefixing in the automobile body shop and the material loading. Process planning for these activities, therefore, are decided mainly by experiences, which caused many repeated rework of the processes and the inconvenience of the workers, and resulted consequently in the reduction of the productivity and the safety of the workers. In this paper, the optimal dimension of the welding gun and its handle position and the optimal working path is simulated and decided by use of DELIMN/IGRIP and DELMIA/Ergo and the working area modelized in the virtual workcell of DELMIA.

PURPOSES : This study is to develop speed correction factor for more realistic Level-of-Service(LOS) at multilane highway. METHODS : In this study, we compared speed difference the degree of speed reductions in actual multilane road conditions with speed reduction considering speed correction factor presented in highway capacity manual using statistical techniques. And also we presents new speed correction factor analyzing collected data at national highway No.1 (Goyang~Wolrung). RESULTS : The result of analyzing and comparing new suggested speed correction factor with speed correction factor in Korea Highway Capacity Manual (KHCM) shows RMSE (Root Mean Square Error) in new speed correction factor (RMSE 1.5) is much lower than existing speed correction factor (RMSE 13.4). New suggested speed correction can be used for analyzing Level-of-Service at multilane highway. And also we suggests improvements for analysis procedure in analyzing Level-of-Service at multilane highway CONCLUSIONS : As a result of comparing differences, we draw the causes that effect the differences in speed and suggest new speed correction factor that consider traffic volumes. It can be more rational because it uses speed correction factor which can consider more realistic traffic conditions, etc.
