Objectives : The mechanical properties of Korean electric cupping systems are studied via experimental measurements. The study aimed at establishing the fundamentals of industrialization and systemization of oriental medicine device industry, as well as improving the quality of life for many Koreans. Methods : We reviewed the studies on traditional cupping as well as modern one to fine necessary factors for electric cupping systems. To characterize the mechanical properties of Korean electric cupping systems, we measured the pressure characteristics of commercially available electric cupping system by using an automatic pressure acquisition system and a standard cup. The pumping capability was checked at 40 seconds, and the stability of the suction cup was checked at 600 seconds. We also acquired the noise level of each system in clinical setting. To check the portability of each system, we also measured its physical dimensions. We scrutinized system manuals provided by the system manufacturers. Results : It took less than 5 second to reach the pressure if the connection between the air hose and the vacuum valve of the cupping system was secure. Pressure diminished to no more than 10% for 600s for all systems. Noise levels were 55~70 dB. Increase in pressure was too fast to control for a designated vacuum level except for one product. Conclusions : The Pumping ability of the systems is impressive and reliable. Pressure retention ability of each cup is quite reliable and reproducible. Therefore, their mechanical performances were worthy of recommendation. Some of them had noise level higher than 60 dB and they were bothersome. It was also suggested that the control for low to middle pressure needed to be accomplished by the cupping system.

A New Sampling and SEC Method for Analysis of Underivatized Cellulose

A new sampling and size exclusion chromatography (SEC) method for the analysis of underivatized cellulose are established. In this method, cellulose materials are first dissolved in N-methylmorpholine N-oxide (NMMO) and diluted by adding dimethyl sulfoxide (DMSO) to make the sample solutions of about 0.1% in 50/50 NMMO/DMSO (w/w). Sample solutions are analyzed using a glucose-treated divinylbenzene (DVB) SEC column and DMSO containing 0.05M LiBr and 2.5 blank as the eluant. The flow rate was constant at 1 mL/min and the whole SEC system including the column was heated at $80^{\circ}C$ to reduce the viscosity of DMSO. Addition of 0.05 M LiBr eliminated SEC baseline drifting, and addition of 2.5 blank seems to reduce the interaction between the sample and the column packing. SEC molecular weights were determined using a calibration curve constructed from a series of narrow pullulan standards, and they were used to measure the degree of degradation during two different pulp-to-sponge processings.

스티칭에 의한 Spectra/비닐에스테르 적층복합재료의 내충격성 변화에 관한 연구

The mechanical and impact properties of the stitched Spectra composite was studied. The Spectra fiber reinforced vinylester composites were stitched with plain stitch to improve mechanical and impact resistant properties. The Spectra liber was used as a stitching thread and the composites were stitched twice in alternating sequence with plain stitch. The stitched composite showed different behavior with stitch densities in tensile and flexural properties. The effect of stitching has been changed with the mechanical properties measured under different restrained condition. The stitching has improved the preserving properties of the woven laminate composite structure by restricting the damage propagation.

A 25-month-old boy was referred to the hospital due to large head detected on routine physical examination. At visit, dysmorphic facial appearances, including broad nose, prominent forehead, and coarse face, were noted. Nasal obstruction with nasal voice, prominent adenoids, and bilateral middle ear effusions were detected. His abdomen was distended, and liver and spleen were palpated about 3 finger and 2 finger breadths, respectively. He was operated for bilateral inguinal hernias. The motion of both elbow joints was mildly limited on supination and pronation. Urinary level of glycosaminoglycan was elevated and the enzyme activity of iduronate sulfatase in leukocytes was decreased. The mutational analysis of the gene iduronate 2-sulfatase (IDS) revealed c.263G>A (p.Arg88His) mutation. His developmental scale showed delayed development and there was cardiac valvular involvement (tricuspid regurgitation and mitral valve prolapse). After the diagnosis of Hunter syndrome, enzyme replacement therapy started on a weekly basis without progression of any clinical features. Here we report a case of early diagnosed Hunter syndrome detected by large head on routine examination. Thus, it is important to associate Hunter syndrome in the patient with large head especially, if there is the history of bilateral inguinal hernia and prominent adenoids to increase the possibility of early diagnosis and treatment.

In this paper, we propose the direction of development for EOD robot. We collected and analyzed the opinions of EOD teams. In order to verify the opinions, we conducted QFD(Quality Function Deployment) analysis. Based on the QFD analysis, we work out the priority of EOD robot development. And we establish the goal of development(target system) and suggest the development direction of EOD robot on each issue.

Recently, the study on small-sized reconnaissance robot has been progressed through grafting robot technology to military fields for minimizing the casualties. Especially, throwable robots have been focusing for their's efficiency in anti-terror operation. However, it is impossible to launch throwable robot to long range(approximately 100m) by hand. So we need another type of robots, so called launchable robots, which can launch farther and is more accurate by launcher. In this paper, we presented the process of developments of launchable robots('launchbot') which are available for remote launch from collection of user's opinions to field test. Based on the opinions of users, we established the goal of development, designed and manufactured the robots. Through the field test, we found that our launchable robot satisfied the performance requirements.
