Feature detection is important in various mesh processing techniques, such as mesh editing, mesh morphing, mesh compression, and mesh signal processing. In this paper, we propose a geometric snake as an interactive tool for feature detection on a 3D triangular mesh. A geometric snake is an extension of an image snake, which is an active contour model that slithers from its initial position specified by the user to a nearby feature while minimizing an energy functional. To constrain the movement of a geometric snake onto the surface of a mesh, we use the parameterization of the surrounding region of a geometric snake. Although the definition of a feature may vary among applications, we use the normal changes of faces to detect features on a mesh.

The aim of this study was to evaluate effects of short-tenn repetitive-bilateral excercise on the activation of motor network using functional magnetic resonance imaging (fMRI). The training program was performed at 1 hr/day, 5 days/week during 6 weeks. Fugl-Meyer Assessments (FMA) were performed every two weeks during the training. We compared cerebral and cerebellar cortical activations in two different tasks before and after the training program: (1) the only unaffected hand movement (Task 1); and (2) passive movements of affected hand by the active movement of unaffected hand (Task 2). fMRI was performed at 3T with wrist flexion-extension movement at 1 Hz during the motor tasks. All patients showed significant improvements of FMA scores in their paretic limbs after training. fMRI studies in Task 1 showed that cortical activations decreased in ipsilateral sensorimotor cortex but increased in contralateral sensorimotor cortex and ipsilateral cerebellum. Task 2 showed cortical reorganizations in bilateral sensorimotor cortex, premotor area, supplemetary motor area and cerebellum. Therefore, this study demonstrated that plastic changes of motor network occurred as a neural basis of the improvement subsequent to repetitive-bilateral excercise using the symmetrical upper-limb ann motion trainer.

The Streptomyces coelicolor M145 genome harbors six copies of divergent rRNA operons that differ at ${\sim}0.2%$ and ${\sim}0.6%$ of the nucleotide positions in small subunit (SSU) and large subunit (LSD) rRNA genes, respectively. When these rRNA genes are expressed, a single cell may harbor three different kinds of SSU rRNA and five kinds of LSU rRNA. Primer extension analyses revealed that all of the heterogeneous rRNA molecules are expressed and assembled into ribosomes. This finding and the maintenance of the intragenomic variability of rRNA operons imply the existence of functional divergence of rRNA species in this developmentally complex microorgamsm.

The purpose of this study is to find out the influence of Physical Therapists' heavy work on their cervical spines. Subjects were 80 members of Physical Therapists, 40 males and 40 females who were between 3rd decades to 4th decades. The Cervcial Range of Motion instrument was used to measure six cervical range of motion such as flexion, extension, left and right lateral flexion, left and right rotation. The degree of rotation and both lateral flexion was appeared as decrement in 4th decades than 3rd decades(P<0.05). And the left lateral flexion in female Physical therapiest was increased than in male ones(P<0.05). By this results, it was proved that the older the PT's age, the less the cervical motion range and there were more decrement in male Physical Therapists than female Physical Therapists. And finally I think that the evaluating method used in this study will be clinically very useful and be a basic raw materials for evaluating the existence and the degree of functional disability as in the occupational hazards due to Physical Therapist's heavy work.

Removable protective adhesives for automobiles were synthesized by an emulsion polymerization of monomers such as n-butyl acrylate (BA), n-butyl methacrylate (BMA), acrylonitrile (AN), acrylic acid (AA) and 2-hydroxyethyl methacrylate (2-HEMA), in which AA and 2-HEMA were functional monomers. Potassium persulfate (KPS) was used as an initiator and sodium lauryl sulfate (SLS) was used as an emulsifier, and polyvinyl alcohol (PVA) was used as a stabilizer. Emulsion polymerization was carried out in a semi-batch type reactor. Tensile strength, extension, peel strength, viscosity and solid content of the synthesized adhesives were tested. The optimum physical properties of the removable protective adhesives for automobiles were obtained with the composition of 0.43 mole BA, 0.57 mole AN, 0.21 mole BMA, 0.03 mole AA, and 0.03 mole 2-HEMA.

Background: The purpose of this study was to investigate the immediate effect of thoracic self mobilization on balance and gait of acute stroke patients. Methods: Patients (n=10) with acute stroke applied to thoracic self mobilization. There are two thoracic self mobilization of both extension and rotation. Each thoracic self mobilization was performed ten times per direction in a total of three sets and the total time required for two thoracic self mobilization was twenty minutes. The break time between sets was one minute. Balance ability was measured using the timed up and go test and the five times sit to stand test for patients. The 10 meter walk test and the functional gait assessment were used for measurement of gait ability for patients. Results: Significant improvements were observed on balance ability (p<.05) and gait ability (p<.05). Conclusion: These results show that thoracic self mobilization is immediate effective on balance and gait ability. Thus, thoracic self mobilization will help recovery of balance and gait ability in acute stroke patients.

Purpose: The study was conducted to examine the effects of motivational interviewing intervention on exercise performance and maintenance, exercise and pain self-efficacy, functional status, and quality of life in the patients with total knee replacement. Methods: This study used a nonequivalent control group non-synchronized design. A total of 100 patients with total knee replacement (33 patients in motivational interviewing group (MG), 33 patients in exercise group (EG), 34 patients in comparison group (CG)) were participated in this study. MG and EG had 7 scheduled sessions for 4 weeks. Data were analyzed with repeated measures ANOVAs by using IBM SPSS Statistics 20. Results: MG showed better exercise maintenance, higher exercise and pain self-efficacy, higher muscle strength, and mental component of quality of life than the other groups. MG and EG showed better knee flexion, less knee extension, longer walking distance for 6 minutes, and better functioning than CG. Conclusion: The results showed that motivational interviewing intervention is an effective intervention for elderly patients with total knee replacement. Future study examining long term effects of motivation interviewing intervention is necessary.

Hypopharyngeal cancer usually has invasiveness to adjacent tissue and frequent metastasis to cervical lymph node. In addition, because it often accompanies submucosal extension and second primary malignancy, the sacrifice of larynx and postoperative radiation therapy had been performed in the past. However, it has been reported that conservative surgery of hypopharyngeal cancer show good functional and oncologic outcome according to the development of diagnostic tool and reconstructive technique. We report a case of hypopharyngeal cancer that received conservative surgery followed radiation therapy and intraoperative radiation therapy for neck recurrence.

This study aims to convey some results of a survey to professionals in the fields of territorial studies and information studies, mainly concerned with spatial implications of the informatization processes, and to draw some policy implications. Overall findings of the survey show that, along with jnformatization processes, there is high possibility of enforcing the functions and role of the metropolitan Seoul while diffusion of population and polarization reversal is quite feasible to some degree. The extension of large cities will be possible but with some limitations while urban structure will be characterized with limited functional segmentation and the emergence of multi-centers. It is prospected that there will be higher possibility of achieving regionally balanced development by informatization processes.

Pop art, an artistic trend which was actively popular centering around popularization of America in the 1960's, appears as punk style in the 1970's and as one of diversified style in the 1980's, and have co-existed in the third culture and pluralistic combination since the 1990's. The image of pop art includes complexity, familiarity and popularity as well as extension of media, and so directly influences the fashion in the end of the 20th century. Especially, sportslook show up by the virtue of rising lower cultural area such as street fashion becoming influential and change in life style, which was recreated as clothes by developing characteristics of design including style, details and colors showed in active sports wear. This study is aimed to ana analyze the image of pop art showed again in the modern fashion in the end of the 20th century and graffiti-art which was well known to the general public after the 1980's. Through this analysis, I will study characteristics of pop art showed in sportslook which is the mainstream in modern fashion and graffiti of Keith Haring. Consequently, I suggested a functional, esthetic and future-oriented sports look design which comprises the image of the graffiti-art of Keith Haring by using Design CAD(photoshop & primavision) enabling to attempt variously and to derive quickly the output of design and textile.
