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.

The spice phenomenon therapy is to adhibit aromatic herbs or materials to the human body or clothing, for the purpose of preventing and treating diseases. Mankind found the fire, and found that some plants and trees give off smoke when they are burning. Then, they found that some of aromatic substances had certain actions after being absorbed through the respiratory organ, which was the beginning of the spice phenomenon therapy. The spice phenomenon therapy is effective to relieve the exterior syndrome, to eliminate dampness, to regulate Qi flow, and to induce resuscitation. It has two actions. One is that the aromas that permeated the body, refreshes the mind, stimulates the appetite, strengthens the spleen and the stomach, and makes a relaxing sleep. The other is that the aromatic substances, absorbed into the human body, have pharmacological actions. The volatile aromatic substances have various pharmacological actions such as stimulating cranial nerves, dilating cardiac blood vessels, promoting gastric secretion, relaxing and sleep-inducing. It has been proved that the spice phenomenon therapy is anti-inflammatory and anti-microbial and is effective to dilate cerebral blood vessels and to ease the pain. It is expected to be studied more aggressively.

N/A The effects of In and Be additions on the aging behaviors and mechanical properties in the Al-Cu-Li alloy were investigated using the transmission electron microscope, the scanning electron microscope, hardness and tensile strength measurement. The aging is promoted and the double hardness peak is appeared by the addition of In and Be in the Al-Cu-Li alloy. The strength is increased, but the elongation and toughness are decreased by the addition of In in the Al-Cu-Li alloy. And the Al-Cu-Li-In-Be alloy has good combination with the strength, the elogation and toughness than Al-Cu-Li-In alloy.

This study analyzes the impacts of agricultural water shortages in Korea using a combined top-down and bottom-up model. A multi-region multi-output agricultural sector model with detailed descriptions of production technologies and water and land resource constraints has been combined with a standard CGE model. The impacts of four different water shortage scenarios were simulated. It is shown that an active adaptation of crop choices occurs in even the regions with relatively abundant water resources in order to respond to the change in relative output prices caused by water shortages. We found that although the losses in production values are not quite large despite water shortages due to the price feedbacks, the loss in GDP is substantial. We show that our combined approach has advantages in deriving region and product specific production effects as well as the overall GDP loss effect of water shortages.

Separation and Characterization of Dust and Ground Water Particulates Using Gravitational SPLITT Fractionation.

이승호,박희영,이상근,용성권,음철훈,Lee, Seung Ho,Park, Hui Yeong,Lee, Sang Geun,Yong, Seong Gwon,Eum, Cheol Hun Korean Chemical Society 2001 Bulletin of the Korean Chemical Society Vol.22 No.6

Split-flow thin (SPLITT) cell Fractionation(SF) is a technique that allows separation of particulates and macromolecules into two fractions. A gravitational SF(GSF) system is constructed and tested for its applicability for separation of dust and ground water particulates. When tested with polystyrene latex particles, experimental data were in good agreements with theory. The 9.8 and 21.4㎛ polystyrene particles were successuflly separated in a continuous mode, where the mixture is continuously fed into the GSF channel allowing separation in a large sacle. The GSF system is successfully applied to continuous separation of dust and ground water particels based on the sedimentation coefficient, which is closely related to the particle size. The separations were confirmed by microscopy and energy-dispersive X-ray (EDX) analysos.

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.

치과용 임플란트 실패의 주요 원인은 임플란트 표면에 부착되는 세균의 침착의 결과로 생기는 임플란트 주위염이다. 구강 내에서 세균성 치태의 침착은 치태가 부착하는 기질 표면의 물리적 성상과 타액성 피막의 성분에 영향을 받으며 형성된 피막의 유기질 성분의 차이가 치태의 성분과 병원성에 영향을 미친다. 최근 연구에 의하면 생체재료의 표면에 침착되는 치태세균은 사용되는 재료에 따라 특이한 세균 침착을 보이며 이는 초기 타액성 피막의 차이에 의한 것으로 알려져 있다. 이 연구의 목적은 플라즈마분사법으로 표면 처리된 타이태늄 임플란트에 흡착되는 타액성 단백질 피막의 특성을 정성적인 방법으로 분석하는 데 있었다. 법랑질 조각과 플라즈마분사법으로 표면 처리된 타이태늄 임플란트를 스프린트에 치실을 이용하여 연결한 장치를 구강 내 장착하여 2시간 동안 피막이 침착되게 한 후 피막을 분리 추출하여 냉동 건조시켰다. 재수화 과정을 거치고 나서 전기 영동법과 Western transfer 분석을 통해 단백질 성분에 관한 분석을 시행하였다. 사람의 총 타액과 이하선 타액 및 악하선-설하선 타액을 수집기를 이용하여 채취하고 같은 방법으로 처리한 후 성분분석을 실시하였다. 피막 흡착 전후의 표면변화를 주사전자현미경을 이용하여 관찰하였다. 실험결과 타이태늄 임플란트에 흡착된 피막은 법랑질 표면의 피막과는 다른 단백질 성분을 가지고 있었으며, 주로 악하선-설하선 타액에서 유래하였다. 임플란트와 법랑질 표면 모두에서 흡착된 피막에는 아밀라제, 분비성 면역 글로불린A 및 락토페린이 존재함을 알 수 있었으나 법랑질의 경우는 blotting이 약하게 나타났다. 주사전자현미경 관찰결과 시편의 표면에 균질한 피막이 덮고 있었으며 세균의 부착은 거의 관찰되지 않았다. 이상의 실험 결과들을 통하여 플라즈마분사법으로 표면 처리된 타이태늄 임플란트 표면에 부착된 타액성 단백질 성분은 법랑질과는 차이가 있음을 알 수 있었으며, 이러한 차이는 치태세균의 종류 및 병원성에 영향을 미칠 것으로 생각된다. 법랑질과 타이태늄 임플란트는 기질과 표면구조가 다르므로 표면에 형성 되는 치태성분도 다르다는 사실과 본 연구 결과를 종합하여 볼 때, 타이태늄 임플란트 표면에 흡착되는 초기 타액성 단백질의 성불이 타이태늄 표면에 침착되는 미생물 군의 조절에 중요한 역할을 가지고 있으며, 임플란트 치료 시에 올바른 치태 관리법의 교육을 통하여 환자 스스로 적절한 관리를 하도록 함으로써 임플란트 치료의 성공률을 높일 수 있을 것으로 생각된다.
