  • Pulse diagnosis is considered one of the most important diagnostic methods in traditional Korean medicine. Nonetheless, there have been troubles of using pulse diagnosis practically, for the lack of its differential standards and standardized terminology. Rapid pulse belongs to the several traditional pulse types. Rapid pulse was first mentioned in the chinese medical book Haungdineijin that matched it to the fever as well as yang in the human body. Meanwhile, chinese doctors in Ming Ching dynasty of China suggested that rapid pulse meant more of the yin, cold-related reaction than yang and fever. In this study, we organized the past arguments of the rapid pulse and went back tracking what biological activities could be possibly linked to the rapid pulse. Thus, we figured out that the inflammatory mechanism has a close connection with the rapid pulse. The definition of the rapid pulse in Haungdineijin was indicating the acute inflammatory response, while in Ming Ching dynasty, it indicated the chronic inflammation. This is the deficiency-excess pattern of the rapid pulse. Furthermore, we discussed the nonexpression pattern of the rapid pulse which could be happened in case of the heat stroke, etc.

  • Selections for rapid and slow walking behavior were carried out with the populations, drived from Oregon-R and lethal free strain of Drosophila melanogaster. The behavior was measured by means of connected test-tube apparatus. The populations responded effectively to the artificial selection, and it reached the selection plateau after 7 generations. The realized heritability for the first 10 generations was estimated to be about $9\\sim14%$ for the rapid walking behavior, and those for slow walking behavior was about $11\\sim16%$. The results of hybridization analysis between selected populations at generations 8 and 10 indicated that some polygenes showing a slow walking behavior were partially dominant over polygenes controlled rapid trait. The populations selected for rapid and slow walking behavior were relaxed after 10 generations of selection. The response to natural selection of rapid population was completely returned to their neutral states after only 5 generations. Such phenomena would be explained by the genetic homeostasis resulted from an action of natural selection. However, the slow population did not make any difference from walking scores of their original artificial selection. It seems reasonable to assume that the slow walking behavior was possibly controlled by a major gene.

  • The combination of rapid prototyping(RP) and rapid tooling(RT) has a potential for rapid manufacturing of three-dimensional parts. In the present study, a new RP system transfer type Variable Lamination Manufacturing using Expandable Polystyrene Foam (VLM-ST), is proposed to fabricate net shapes of three-dimensional prototypes. Various three-dimensional parts, such as a knob shape and a human head shape, are manufactured by the VLM-ST apparatus. In addition, a new rapid tooling technology, which utilizes a room temperature vulcanizing (RTV) molding technique and a triple reverse process technique, is proposed to manufacture net shapes of three-dimensional plastic parts using the prototypes of VLM-ST. A plastic part of the knob shape is produced by the proposed RT technology. The combination of the proposed RP and RT enables the manufacture of a plastic knob within two days.

  • Purpose: Hypovolemia is not uncommon among trauma patients in the emergency department (ED). Successful resuscitation of a hypovolemic patient often requires rapid intravenous administration of massive amounts of fluid. A rapid fluid infuser is used in the ED for this purpose, there have been no studies of their clinical uses and effectiveness. We studied clinical experience with a rapid fluid infuser at an urban university hospital in Seoul, Korea. Methods: We reviewed the medical records of 38 patients admitted to the ED with a history of application of a rapid fluid infuser from January 2004 to July 2005. Adult trauma patients older than 15 years of age were included in this study. Clinical data on the patients and the volume of fluid used to achieve a stable blood pressure were extracted from their medical records. Results: The total number of adult trauma patients with a history of application of a rapid fluid infuser from January 2004 to July 2005 in the ED was 16. The mean systolic blood pressure for deciding to apply the rapid fluid infuser was $74.9{\pm}12.7mmHg$. The mean time and volume used to achieve a stable blood pressure were 40.4 min and$2947.3{\pm}1339.2ml$, respectively. In all patients, the amount of fluid infused before using the rapid fluid infuser was between 500 ml and 10,000 ml, compared to 1,000 ml and 6,200 ml with the rapid fluid infuser. The mean amount of fluid per min. via the rapid fluid infuser was 85.5 ml. Vital signs were stabilized in 11 patients, 6 of the 11 were discharged alive. Conclusion: The mean amount of fluid delivered per min. via the rapid fluid infuser was much less than expected; thus, there should be clinical guidelines on volume resuscitation with a rapid fluid infuser in the ED. In the future, prospective, multicenter, clinical-data collection is needed for a more sophisticated study.

  • Rapid and accurate data processing is required in many GPS(Global Positioning System) applications including surveying. While one can use four different kinds of GPS satellite orbits, we evaluated the accuracy and precision of each kind of orbits to find the best candidate for rapid and accurate data processing. The four different kinds of orbits we: broadcast orbits from GPS satellites; and ultra-rapid orbits, rapid orbits, and precise orbits provided by international GPS data analysis centers such as IGS. With GIPSY and ultra-rapid orbits, we could get the positioning accuracy of 1.5cm from seven days of GPS data. From this study, we conclude that rapid and accurate data processing is achieved with GIPSY and ultra-rapid orbits.

  • The Rapid Prototyping and Tooling technology has been developed. However, most commercial ones currently use resins or waxes as the raw materials. These days. the direct metal deposition methods are researched as a true rapid prototyping and tooling technology. A fundamental study on rapid prototyping and tooling with wire welding technology using $CO_2$ laser radiation was carried out in this paper. The main focus is to develop a simple commercial rapid prototyping and tooling system with the exiting laser welding technology. The process is investigated as a function of laser parameters and process variables. Basic parts were fabricated as out-put and their microstructure, hardness and tensile strength are examined for the reliability. In addition, Its advantages and disadvantages are discussed as a rapid prototyping and tooling system.
