  • Objectives: The propose of this study is to find out the clinical application of conservative treatment to 3 patients who has Disc Extrusion on L-spine MRI Methods: We examined 3 patients with Lumbar Intervertebral Disc Herniation (HIVD of L-spine) with Disc Extrusion who showed changes on MRI images before/after the treatment among HIVD of L-spine patients who visited Jaseng Hospital of Oriental Medicine. Results: In this study, the first MRI examination of HIVD of L-spine patients was performed at the first visit and re-examination of MRI was done after the treatment. In each case, the size of the extruded disc was considerably reduced in MRI image. Low back and leg pain was also reduced significantly after conervative oriental medical treatment. Conclusions: Conservative oriental medical treatment can be effective for improving symptoms of HIVD, decreasing pain, also decreasing the volume of herniated disc.

  • This study deals with the heat transfer analysis on phase change optical disc with land/groove recording by means of numerical method. Finite difference time domain(FDTD) method was used to obtain the amount of absorption of light propagating inside disc and finite difference element(FEM) method was used to calculate the temperature distribution. The calculated results present the detailed information of recording characteristics on the phase change optical disc. The temperature profiles are quite different between the land track and the groove track. The recorded mark shape on land track is smaller and more elliptic than that on groove track. It is shown that the thermal problem to the neighboring track takes place due to secondary peaks. It is found that the different write strategy should be applied to land and groove recording, respectively.

  • A study on tidal turbine using CFD simulation has been an economical and reliable method. However, large flow fields with multi-turbine arrays require high computer performance. Actuator disc theory therefore is widely applied. Actuator disc is the concept that imitates actual turbine by means of an energy absorption disc which has the same dimension and characteristics. Turbines installed in array may have disturbance effects on one another. Thus, the subject of this study is to analyze the far wake of these tidal turbines and compare to single turbine case. The main objects are to analyze two turbines positioned longitudinally at different spaces.

  • Objectives : The aim of this study is to investigate radiological changes in cervical disc herniation after oriental medical treatment. Methods : 9 patient diagnosed as cervical disc herniation by MRI were treated with oriental medical treatment and underwent a follow up MRI study. Results & Conclusions : Comparison of initial MRI with follow-up MRI showed that 2 of the herniations dimensions decreased between 1% and 25%, 1 decreased between 26% and 50%, 5 decreased between 50% and 75%. The mean disc herniation dimensions decrease was 40% in 9 patients. Comparison of initial MRI with follow-up MRI showed that 4 of the herniations diameter decreased between 1% and 25%, 2 decreased between 26% and 50%, 3 decreased between 50% and 75%. The mean disc herniation diameter decrease was 36% in 9 patients.

  • For the manufacturing lightweight fine aggregate, clay and waste material was formed by pelletizer. The fine aggregate of 1-5 mm diameter was formed by diameter 76 cm pelletizer disc. Pelletization variables were : (1) pelletizer disc angle, (2) speed of revolution of pelletizer, (3) added pelletization time. Green and sintered aggregate were measured specific gravity, absorption rate and average size. The optimum condition were found that the pelletization variables were angle at $70^{\circ}$, speed of revolution of pelletizer at 23.2 rpm, and water/solid ratio at 1/5. At these conditions, it was formed that fine aggregate green whose average size was $2.0{\sim}3.35mm$. Specific gravity and average size are increased with low angle of disc and fast revolution speed of disc. Specific gravity and average size were not distinctly influenced by added pelletization time. Sintered aggregate was distinctly influenced by properties of green.

  • Objective: The purpose of this study was to report the radiological and symptomatic changes in a patient with acute herniated lumbar disc due to coughing, treated with megadose pharmacopuncture and combined Korean medicine. Methods: MRI examination diagnosed an acute lumbar disc herniation by coughing. We performed a combination treatment of megadose pharmacopuncture and integrated Korean medicine. NRS, ODI, EQ-5D, SLR test, and big toe extension test were checked on admission, after two weeks, on discharge, and after four months to confirm symptom improvements. Results: In the acute stage of lumbar intervertebral disc rupture, megadose pharmacopuncture combined with Korean medicine treatment showed improvement in NRS, ODI, EQ-5D, SLRT, and big toe extension tests. In addition, absorption of the herniated intervertebral discs was observed through an MRI scan on discharge. Conclusions: For patients with herniated lumbar disc acutely deteriorated by coughing, a combination of megadose pharmacopuncture with Korean medicine treatment may be a solution.

  • In this study, soda lime was prepared from slaked lime to expand the scope of limestone use. To evaluate carbon dioxide absorption, an extruder-type and disc-type pelletizers were used to make the soda lime using bentonite as an additive. Regardless of the pelletizing process, the peak of CaCO3 was confirmed in soda lime due to its reaction with carbon dioxide. Furthermore, it was confirmed that both calcite and aragonite were present together. The soda lime prepared using the disc-type pelletizer showed a larger specific surface area than that prepared using the extruder-type pelletizer did, and the specific surface area improved on adding bentonite. The carbon dioxide absorption rate increased under the sample condition with an enhanced specific surface area.

  • A series of coupled-hemicyanine dyes with alkylene spacer were successfully synthesized by a reaction of coupled aldehydes with corresponding salts, respectively. These coupled dyes had more excellent thermal properties (high decomposition temperature, stiff decomposition behavior) and higher molar absorption properties than an uncoupled dye. The coupled dyes with perchlorate anions showed the strongest exothermic decomposition while those with hexafluorophosphorate anions showed endothermic decomposition. As the coupling length (n=3, 4, 5, 6) increased, thermal properties decreased and dyes with even spacer was more thermally stable than dyes with odd spacer. Among several coupled dyes, C4-NP-ClO4 and C4-Cl-ClO4 exhibited the best recording properties with the lowest jitter value of 7.5∼9.5% in authoring disc.
