This study was designed to investigate the side shift of orbiting condylar movement by direct measurements from tracings of Denar pantograph. It is well known that side shift has much influence on the articulating surface of teeth. In this study, after locating the ture hinge axis point with Denar hinge axis locatior, the recordings of Mandibular movement were obtained from Denar pantographic recording assembly, and immediate side shift and progressive side shift were measured. For this study, 20 dental studnts who have no missing teeth and no difficulties of mandibular movement and 4 patients who were, treated by occlusal therapy were selected. The results obtained were as follows, 1. The prevalence of immediate side shift was 42%, and the immediate side shift of greater than 0.5mm was only 17%. 2. The mean of immediate side shift (20 of 48) was 0.38mm, that of right lateral excursion (7 of 24) was 0.27mm, and that of left lateral excursion (13 of 24) was 0.44mm. 3. The mean of progressive side shift was $7.21^{\circ}$ that of right lateral excursion was $6.46^{\circ}$, and that of left lateral excursion was $7.96^{\circ}$.

The purpose of this study was to investigate the effects of active and passive postural perturbation on ankle dorsiflexor responses in stroke patients. The subjects consisted of 13 stroke patients. Using wireless electromyography, the patients' ankle dorsiflexor muscle responses were measured under the following conditions: active dorsiflexion (AD), active perturbation (AP), and passive perturbation (PP). Tibialis anterior muscle activity increased most significantly during PP of the affected side ($118.64{\pm}56.28$). The most significant increase for the non-affected side was in AD ($72.64{\pm}24.56$). Tibialis anterior muscle activity was compared under each condition. The affected side showed significant differences between PP and AD and between PP and AP (p<.05). The non-affected side showed not significant differences between each condition. The ratios of tibialis anterior muscle activity under AP to that under AD were 1.00 on the affected side and .75 on the non-affected side and the difference was not significant (p>.05). The ratios of tibialis anterior muscle activity under PP to that under AD were 3.30 on the affected side and 1.14 on the non-affected side and the difference was significant (p<.05). Passive perturbation improved tibialis anterior muscle activity on the affected side, and training based on this approach may have the potential to improve the ankle dorsiflexion of people with stroke.

Attenuated PSM lithography 공정에서 overlay margin 확보 및 side-lobe 제거를 위해 기존의 Cr shield 방식의 단점인 복잡한 mask 제작공정과 구조를 단순화하기 위한 방법으로 scattering bar 방식을 제안하였다. Scattering bar는 Cr 보조패턴처럼 완전히 빛을 차단하는 것이 아니라 약간의 빛을 투과시켜 보강된 intensity를 상쇄하므로 side-lobe를 억제하는 방법으로 metal pattern을 생성할 때 scattering bar도 동시에 만들어 mask제작에 필요한 공정횟수를 줄이고 mask구조 역시 단순하게 한다 그리고 동시에 DOF(depth of focus)를 향상시킨다. Background clear pattern의 경우에 발생하는 side-lobe도 scattering bar를 이용하여 효율적으로 제거되었다.

Background: A number of researchers have attempted to improve the balance of stroke patients, however there is still a question as to whether taping is effective in increasing balance. Objective: To determine the effect of paretic and non-paretic side taping on the balance ability in patients with stroke. Design: A single-blind randomized controlled trial Methods: This randomized single-blind controlled clinical trial with a repeated measures study included 45 subjects who were randomly assigned to paretic side taping groups (n=15), non-paretic side taping groups (n=15), and trunk exercise groups (n=15). Trunk exercise and paretic side taping groups had taping on the paralyzed erector spinae, while the non-paretic side taping group had taping on the non-paralyzed erector spinae. Trunk exercises were performed for 30 minutes to promote core muscles. The balance ability measured the center of pressure movement (paretic side, non-paretic side,forward, backward, limit of stability) in the sitting position. All measurements were evaluated using BioRescue. Results: All three groups showed significant increase in all variables after 4 weeks. The paretic and non-paretic side taping groups had a significant increase in all variables after 30 min of attachment. However, there was no significant difference among the three groups. Conclusions: Paralysis and non-paralysis taping improved the balance ability of patients with stroke in an immediate effect of 30 min. However, after 4 weeks of intervention, taping with trunk exercise did not differ from single trunk exercise. In future studies, various analyses need to be conducted through more diverse evaluations.

Background: Efficacy of childhood cancer treatment in low-income countries may be impacted by parents' and health-care providers' perspectives on chemotherapy-related side-effects. This study explores prevalence and severity of side-effects in childhood cancer, and compares health beliefs about side-effects between parents and health-care providers, and between nurses and doctors in Indonesia. Materials and Methods: Semi-structured questionnaires were filled in by 40 parents and 207 health-care providers in an academic hospital. Results: Parents exporessed a desire to receive more information about side-effects (98%) and worried about this aspect of treatment (90%), although side-effects were less severe than expected (66%). The most frequent was behavior alteration (98%) and the most severe was hair loss. Only 26% of parents consulted doctors about side-effects. More parents, compared to health-care providers, believed that medicines work better when side-effects are more severe (p<0.001), and accepted severe side-effects (p=0.021). More health-care providers, compared to parents, believed that chemotherapy can be stopped or the dosage altered when there are side-effects (p=0.011). More nurses, compared to doctors, stated that side-effects were unbearable (p=0.004) and made them doubt efficacy of treatment (p<0.001). Conclusions: Behavior alteration is the most frequent and hair loss the most severe side-effect. Apparent discrepancies in health beliefs about side-effects exist between parents and health-care providers. A sustainable parental education program about side-effects is recommended. Health-care providers need to update and improve their knowledge and communication skills in order to give appropriate information. Suchmeasures may improve outcome of childhood cancer treatment in low-income countries, where adherence to therapy is a major issue.

There is a little scientific documentation reporting the stress, distribution to the edentulous mandible by different concepts of occlusal scheme. So, this study was to investigate the hypothesis that the magnitude and distribution of the occlusal stresses, transmitted through a mandibular complete denture base to the edentulous mandible, would be influenced by the lingualized occlusion. This investigation was performed to analyze the stresses induced in a three-dimensional photoelastic edentulous mandible, when a load is applied to the denture arranged into lingualized occlusion in centric relation, lateral and protrusive functional position. The mounted denture on a Dentatus Type ARO articulator was loaded in a pure vertical direction with 15kgs on the center of articulator in each case and the stresses were frozen into epoxy edentulous model at $127^{\circ}C$ in the stress freezing furnace. The stress-frozen epoxy models were sliced with diamond disc saw into 4mm thick. The slices were examined with a circular polariscope. The results were as follows: 1. In centric relation, the stresses were low at anteriors, and gradually increase to the premolar, molar area and highest at the first molar and gradually decrease from the second molar and lowest at the retromolar pad region. The lingual side showed higher stresses than labiobuccal side. 2. In lateral functional position, the working side showed higher stresses than the balancing side. In working side, the lingual side showed higher stresses than the buccal side and in balancing side, the buccal side showed higher stresses than the lingual side. 3. In protrusive position, stress distribution was symmetrical on the posteriors and the stresses were concentrated at the labial side of the anteriors.

The side collision reconstruction algorithm is developed using three dimensional car crash analysis. Medium size passenger car is modeled for finite element analysis. Total 24 side collision configurations, four different speed and six different angle, are set up for making side collision database. Deformation index and degree index are built up for each collision case. Deformation index is a kind of deformation estimate averaging displacement of side door of crashed car from finite element analysis result. Angle index is constructed measuring deformed angle of crashing car. There are two kinds of angle index, one is measured at driver's side and the other is measured at passenger's side. Also a collision analysis information in side of cars is used for giving a basis for scientific and practical reason in a reconstruction of the car accident. The analysis program, LS-DYNA3D is utilized for finite element analysis program for a collision analysis. Those database are used for side collision reconstruction. Side collision reconstruction algorithm is developed, and applied to find the collision conditions before the accident occurs. Three example collision cases are tried to check the effectiveness of the algorithm. Deformation index and angle index is extracted for the case from the analysis result. Deformation index is compared to the established database, and estimated collision speed and angle are introduced by interpolation function. Angle index is used to select a specific collision condition from the several available conditions. The collision condition found by reconstruction algorithm shows good match with original condition within 10% error for speed and angle. As a result, the calculation from the reconstruction of the situation is reproducing the situation well. The performance in this study can be used in many ways for practical field using deformation index and degree index. Other different collision situations may be set up for extending the scope of this study in the future.

Bethanechol, a cholinergic agonist, has been recommended for the management of peripheral anticholinergic side effects during the treatment of antipsychotic medications. But there have been few studies which have evaluated the drug interactions of antipsychotics and bethanechol, even the treatment effects of bethanechol on anticholinergic side effects. So the authors have evaluated whether psychopathology and plasma haloperidol and reduced haloperidol concentrations are significantly changed or not when bethanechol was administrated with maintained doses of haloperidol and other coadministrated drugs(such a benztropine). Also we have evaluated the abating effects of bethanechol on anticholinergic side effects during the treatment with haloperidol. Fifteen schizophrenics with higher than 5 of total score of anticholinergic side effects of 'Rating scale for side effect' were assigned to two groups, and bethanechol 30mg/day and 60mg/day were applied on each group for 4 weeks. The daily haloperidol dosages were fixed before 2 weeks of study. We assessed anticholinergic side effects by 'Rating scale for side effect' and psychopathology by BPRS, and plasma haloperidol and reduced haloperidol concentrations by HPLC at baseline, 2nd week and 4th week. The results were as followed, 1) there was no significant change of plasma haloperidol and reduced haloperidol concentration, 2) at baseline, the dosage of haloperidol showed significant correlation with the total score of anticholinergic side effect, but not at 2nd week and 4th week, 3) in 60mg/day group, dry mouth and the total score of anticholinergic side effects were significantly improved, but not in 30mg/day group, 4) there was no significant change of BPRS except withdrawal at 2nd week. These results suggest that coadministration of bethanechol influenced neither on psychopathology nor on plasma haloperidol and reduced haloperidol concentrations and that improved dry mouth and total score of anticholinergic side effects at 60mg/day.
