Chemical Lumbar Sympathetic Block: Comparison of One- Versus Two-needle Techniques Chul-Jun Mun, M.D., Kyu-Jong Lee, M.D., Sang-Gon Lee, M.D., Jong-Il Kim, M.D.^* Jong-Suk Ban, M.D., and Byung-Woo Min, M.D. Department of Anesthesiology, Fatima Hospital, Daegu, Korea ^*Kim Jong Il Pain Clinic, Daegu, Korea Background: It was frequently noticed in the course of performing a two-needle sympathectomy, that satisfactory spread of contrast solution could be produced by injection through only one of the needles. This led to a closer examination of the merits of single-needle technique. Methods: Forty patients were randomized into two groups. Patients in the single-needle group (n = 20) were injected at the second or third lumbar sympathetic ganglia, while patients in the two-needle group (n = 20) were injected at the second and thired lumbar sympathetic ganglia. Lumbar sympathetic blocks were performed using 3 ml of alcohol and the spread of injectate was verified with C-arm fluoroscopy. The indicators of a successful sympathetic block are increasing skin temperature, decreasing pain, and anhidrosis in the distal extremity. Results: The duration of anhidrosis was 12.2 ?? 2.6 months (mean ?? SD) in the single-needle group versus 13.6 ?? 3.6 months (mean << SD) in the two-needle group. Conclusions: As these results were not significantly different from those obtained in patients having considered to be effective for a neurolytic ;i,bar sympathectomy.

Effects of Clonidine Added to Ropivacaine in Epidural Anesthesia Young-Hoon Cho, M.D., Ji-Hyang Lee, M.D., Sang-Gon Lee, M.D., Jong-Il Kim, M.D.^*, Jong-Suk Ban, M.D., and Byung-Woo Min, M.D. Department of Anesthesiology, Daegu Fatima Hospital, Daegu, Korea ^*Kim Jong Il Pain clinic, Daegu, Korea Background: Clonidine has been regarded as an adequate supplementary anesthetic during epidural anesthesia and has been used with local anesthetics such as bupivacaine or lidocaine to support the effects of these anesthetics. The authors would examine whether clonidine is an adequate supplementary anesthetic when it is used with ropivacaine during epidural ane-sthesia. Methods: Thirty-two healthy patients undergoing a hip or lower limb surgery were diveded into two groups. In group 1, 0.5% ropivacaine 15 ml was administered. In group 2, 0.5% ropivacaine 15 ml combined with clonidine 150 ㎍ was administered. Onset, duration and maximal height of sensory block were assessed. Sedation score, blood pressure and heart rate were measured. Results: Duration of sensory block of group 2 was significantly longer than that of group 1. Sedation score of group 2 was significantly higher than that of group 1. Blood pressure of group 2 was sig-nificantly lower thatn that of group 1 at 50 min, 70 min and 90 min after epidural injection. No significant differences were observed in onset of sensory block and heart rate between the two groups. Conclusions: The addition of clonidine to ropivacaine during epidural anesthesia prolonged duration of sensory block and produced useful sedation. It caused relatively stable hemodynamic changes. These results suggest that clonidine is an adequate supplementary anesthetic when it is used with ropivacaine during epidural anesthesia. (Korean J Anesthesiol 2001; 41: 428~433)

This paper attempts to review and trace back to, based on the data collected during visits of Japanese universities and research institutes, the organizational characteristics, the structures of curricula and study trends, with regard to the fields of social sciences, especially economics and business administration. One of the most conspicuous characteristics observed in academic organizations was Tsukuba university's system whose academic institution was organized around academic grouping, academic genealogy, and specialty: particularly social economic planning belonged to the genealogy of social engineering, in light of its characteristics in term of curriculum, seems to meet the contemporary need. There found two speciality areas in the Department of Social Engineering at the Graduate School: one is the concentration on Mathematical Planning and the other Management Engineering. Considering that its academic goal is tosys tematically and empirically analyze the human behaviors, and to take interdi-sci plinary approach through a policy-oriented system in doing so, it reflects one of the true natures of the academic trend. Their curricula appear to emphasize on analytical methods under uncertainty, application of mathematical planning techniques, system simulation, and information system design and its application, in the area of economics and business administration. Physical education is believed to require modernized facilities and equipments for its record-breaking and technical enhancement, and so increased investment in physical facilities and policy considerations for the training of physical educators are necessary.

In this paper, digitally controlled electronic ballast for the HID lamps driven by proposed frequency conversion method is described. This electronic ballast consists of a buck converter, a low frequency square wave full bridge inverter, a high voltage pulse generator for the lamp ignition, an over current protection circuit and an 8-bit microcontroller. The fuzzy logic digital control operation is carried out by the 8-bit microcontroller. In spite of the limited control bandwidth caused by low operation speed of the 8-bit microcontroller, the good control performance for the constant lamp current in the warm-up period is obtained using the proposed frequency conversion driving method. The HID lamp is controlled in a constant current mode during the lighting warm up process and is controlled in a constant power mode during lighting steady state. A controlled variable power mode is used to extend the lamp lifetime.

The popularity of Social Network Service(SNS) providing web sites has increased continuously and its kinds of service, such as personal connection management, commerce and education, have been diversified. The connection to SNS can be possible not only with conventional PC but also with a variety of mobile devices. Via these tools, SNS users can share lots of information and therefore the service sphere of SNS expands continuously. The identified research result can be outlined more specifically as follows : first, playfulness of SNS quality was giving positive impact to some degree on the user satisfaction; second, flow of SNS quality was giving very positive impact on the user satisfaction; third, responsiveness was giving very positive impact on the user satisfaction; forth, product variety of SNS quality was giving very positive impact on the user satisfaction; fifth, interaction of SNS quality was giving very positive impact on the user satisfaction; sixth, the satisfaction level of SNS quality users gave positive impact on the reuse intention of SNS quality users. It was identified, however, that communication possibility of SNS quality was the factor that did not give much impact on the user satisfaction. This result comes from the analysis that SNS quality is convenient to actively explore and get further information that users wish to find, while they are insufficient in function to provide the information other users require or exchange information among users through the SNS. Key Words : SNS Quality, User Satisfaction, Reuse Intention

Distraction osteogenesis (DO) is a surgical process for reconstruction of combined deficiencies in bone and soft tissue. It involves gradual, controlled displacement of surgically created fractures which results in simultaneous expansion of soft tissue and bone volume. Due to the late introduction of healing by DO in the field of odontology, alveolar DO is increased. The process of alveolar DO involves osteotomy in the area of deficiency, fixation of a healthy segment of bone adjacent the deficient site, transport, and maintenance of newly formed bone. After a 7- or 10-day latency period for soft tissue healing, distraction is performed at the rate of 0.5㎜ twice a day fully to 7㎜. The distractor is then maintained for consolidation after distraction for 10- to 12 weeks. After consolidation, the distractor is removed. Improvement of vertical bone regeneration was achieved in all cases. The resultant distraction zone is filled with natural bone, consistent with the distraction osteogenesis concept. This results in mature cortical bone at the crest for enhanced implant stability and prosthodontic treatment.
