  • This study was designed to examine the effect of aroma massage therapy on lower extremity edema of terminal cancer patients. Methods: A total of thirty-six terminal cancer patients with lower extremity edema were divided into two groups: the aroma massage group received massage with blending oil which was applied from toes to 10 cm above the knee of the subject for 15 to 20 minutes in each turn, while the control group received sham aroma massage (applied with carrier oil only). The circumferences of the fore-foot, ankle and calf were measured before massage and 30 minutes, 2 hours, and 12 hours after massage. The blood pressure, pulse and body temperature were also measured to find the change of subject's physiologic conditions. Results: There were no significant differences in blood pressure, heart rate, body temperature and lower extremity circumferences between two groups. However, edema at each site was slightly improved in the treatment group after the aroma massage therapy, compared to baseline data (P<0.05). In addition, the reduction of lower extremity circumference was maximal at 2 hours in foot, 30 min in right ankle and 12 hours in right calf after aroma massage therapy (P<0.05). Conclusion: Our results suggest that aroma massage therapy is not effective on the lower extremity edema of terminal cancer patients.

  • There has recently been increasing interest in the use of NMDA receptor antagonists as potential neuroprotective agents for the treatment of ischemic stroke. To evaluate the neuroprotective effect of the selective non-competitive NMDA receptor antagonist MK-801 in focal cerebral ischemia, local cerebral glucose utilization (ICGU) was examined in 15 neuroanatomically discrete regions of the conscious rat brain using the 2-deoxy-D[$^{14}C$] glucose quantitative autoradiographic technique 24 hr after left middle cerebral artery occlusion (MCAO). Animals received MK-801 (5 mg/kg i.v.) or saline vehicle before (20-30 min) or after (30 min) MCAO. Both pretreatment and posttreatment of MK-801 increased occluded/non-occluded ICGU ratio in 7 and 5 of the 15 regions measured, respectively (most notably in cortical structures). Following MK-801 pretreatment, there was evidence of widespread increases in ICGU not only in the non-occluded hemisphere (12 of the 15 areas studied) but also in the occluded hemisphere (13 of the 15 areas studied), while MK-801 postreatment did not significantly increase ICGU both in the normal and occluded hemispheres. These data indicate that MK-801 has a neuroprotective effect in focal cerebral ischemia and demonstrate that MK-801 provides widespread alterations of glucose utilization in conscious animals.

  • This study was performed to evaluate cardiopulmonary depressant effects of enflurane (1.0 vol%) combined with propofol(0.25 mg/kg/min) compared with enflurane inhalation, and propofol infusion, respectively, in 18 healthy dogs premedicated with acepromazine and atropine. After bolus injection of propofol 5 mg/kg for induction and tracheal intubation, they were randomly assigned to 3 groups: propofol 0.5 mg/kg/min infusion (Group I, n=6), enflurane 2.5 vol% (Group II, n=6) and enflurane 1.0 vol% combined with propofol 0.25 mg/kg/min (Group III, n=6). Mean arterial Pressure (MAP), systolic arterial pressure (SAP) and diastolic arterial pressure (DAP) were depressed significantly in all groups, especially in Group II. MAP, SAP and DAP values of Group IIIwere higher than those of Group II, but lower than those of Group I. The changes of PaO$_2$, Pa$CO_2$and pHa were similar in all groups. Respiration rates were decreased in all groups 5 minutes after induction but maintained in normal range. Those of Group I were less depressant than those of Group II and Group III. Concentrations of $Na^+ and Cl^-$ were increased and those of $K^+$ were decreased in all groups, but their values were quitely similar. Heart rate was changed in small range and the value of Group I was higher than those of Group II and Group III. Body temperature was decreased significantly in all groups. Adverse effects like as muscle rigidity, nausea or vomiting and shivering were not appeared and apnea at induction was occured 6 dogs. From the these results, enflurane 1.0 vol% combined with propofol 0.25 mg/kg/min also could be applied for anesthesia in dogs.

  • Purpose : To develop a theoretical model for magnetic relaxation behavior of the superparamagnetic nano-particle agent, which demonstrates multi-functionality such as liver- and lymp node-specificity. Based on the developed model, the computer simulation was performed to clarify the relationship between relaxation time and the applied magnetic field strength. Materials and Methods : The ultrasmall superparamagnetic iron oxide (USPIO) was encapsulated with biocompatiable polymer, to develop a relaxation model based on outsphere mechanism, which was resulting from diffusion and/or electron spin fluctuation. In addition, Brillouin function was introduced to describe the full magnetization by considering the fact that the low-field approximation, which was adapted in paramagnetic case, is no longer valid. The developed model describes therefore the T1 and T2 relaxation behavior of superparamagnetic iron oxide both in low-field and in high-field. Based on our model, the computer simulation was performed to test the relaxation behavior of superparamagnetic contrast agent over various magnetic fields using MathCad (MathCad, U.S.A.), a symbolic computation software. Results : For T1 and T2 magnetic relaxation characteristics of ultrasmall superparamagnetic iron oxide, the theoretical model showed that at low field (<1.0 Mhz), $\tau_{S1}(\tau_{S2}$, in case of T2), which is a correlation time in spectral density function, plays a major role. This suggests that realignment of nano-magnetic particles is most important at low magnetic field. On the other hand, at high field, $\tau$, which is another correlation time in spectral density function, plays a major role. Since $\tau$ is closely related to particle size, this suggests that the difference in R1 and R2 over particle sizes, at high field, is resulting not from the realignment of particles but from the particle size itself. Within normal body temperature region, the temperature dependence of T1 and T2 relaxation time showed that there is no change in T1 and T2 relaxation times at high field. Especially, T1 showed less temperature dependence compared to T2. Conclusion : We developed a theoretical model of r magnetic relaxation behavior of ultrasmall superparamagnetic iron oxide (USPIO), which was reported to show clinical multi-functionality by utilizing physical properties of nano-magnetic particle. In addition, based on the developed model, the computer simulation was performed to investigate the relationship between relaxation time of USPIO and the applied magnetic field strength.

  • Purpose : Fever, the most common presenting symptom in pediatric clinics, has been believed to be a dangerous symptom by many parents. Proper recognition about fever will relieve unnecessary anxiety of parents and help them understand the course of the disease. Our objectives of this study were to investigate current parental recognition about fever and to compare these results with those described in 1992. Methods : Between May and July 2006, we questioned caregivers who visited the pediatric outpatient clinic in St.Paul hospital. The questionnaire consisted of 19 items asking about recognition, attitude and management of fever. Results : A total of 136 caregivers were interviewed. Compared with 10 years ago, there were no significant improvements in misconception about fever. Many caregivers (61%) had wrong information about a definition and the way to measure body temperature. There were still high concerns about febrile convulsion and brain damage from fever. Caregivers started treatment at the body temperature which actually needed no therapy. Conclusion : Parents were not aware that fever is just one of physiologic responses and has benefits, which led to unnecessary anxiety and treatment. This misconception has not been changed over the years. Pediatrician should inform parents that fever itself is not harmful and only rational reason for use of antipyretics is to relieve a discomfort of a febrile child. An educational interventions offered by pediatricians will be helpful for parents to have right attitude and understandings toward fever.

  • Background: We evaluate the efficacy of ultra-hydrophilic coated bypass circuits in comparison with uncoated bypass circuits in a porcine cardiopulmonary bypass model. Material and Method: Normothermic cardiopulmonary bypass was peformed in 10 anesthetized pigs via the left atrium and ascending aorta with a centrifugal biopump. Ultra-hydrophilic coated bypass circuits wore used in 5 pigs (the study group) and uncoated bypass circuits were used for the control group. Platelet counts and platelet aggregation tests were peformed. The thrombin-antithrombin(TAT) complex level and total protein level were evaluated. Result: There were no significant changes En the platelet counts and aggregation ability of both groups. The TAT complex levels were not different between the two groups. The total protein level was significantly lower in the control group after cessation of cardiopulmonary bypass. Conclusion: The clinical effects of ultra-hydrophilic coating circuits were not remarkable, in terms of reducing inflammatory reaction and protection of platelet function. However, the effect of protection for blood protein adsorption might be acceptable.

  • Hemorrhagic shock is a common cause of death in the emergency department. The purpose of this study was to investigate the relationship between blood loss as a percent of the total estimated blood volume (% blood loss) and changes in several physiological parameters. The other goal was to achieve an accurate prediction of percent blood loss for hemorrhagic shock in rats using a linear regression model. We allocated 60 Sprague-Dawley rats into four groups: 0ml, 2ml, 2.5ml, 3 mL/100 g during 15 min. We analyzed the heart rate, systolic and diastolic blood pressure, respiration rate, and body temperature in relation to the percent blood loss. We generated a linear regression model predicting the percent blood loss using a randomly chosen 360 data set and the R-square value of the model was 0.80. Root mean square error of the tested 360 data set using the linear regression was 5.7%. Even though the linear regression model is not directly applicable to clinical situation, our method of predicting % blood loss could be helpful in determining the necessary fluid volume for resuscitation in the future.

  • To improve the social and economic position of the disabled people and secure their human rights, an integrated society should be buill. To build such a society, an adequate access should be provided to the movement or in using buildings or facilities. The inconveniences from social life on the part of the disabled people might not result from their impairment or disability, but from physical and social barriers in the environment surrounding them. Therefore, it is necessary to reconstruct entire systems of the society as a disabled people-friendly structure in order to remove those barriers, make them stand their own feet in our communities and freely participate in the social activities. This will eventually lead to build a society in which all people including the disabled people can use those facilities in a more convenient way. It is almost impossible for the disabled people to safely and conveniently access to and use facilities and equipments and freely move to their desired places, without any help from others in Korea. Even though, there are currently many disabled people-related convenience facilities, they have been independently built without a connection with other facilities and buildings, thus not greatly useful. Even when convenience facilities have been built, mostly they are superficially set up; therefore, in many cases, the disabled peOple cannot use those facilities. In this. research, I tried a new concept of mobile wheelchair lift design, which the disabled people can operate without restrictions, when using the public facilities. The key to this research was to develop the existing import-oriented simple functional products to a new system with functional safety and high quality orientation. Also, this research aimed at bringing an. import substitution effect, as well as preempting the mobile wheelchair lift market by advancing into overseas markets through application of new image designs in the field of disabled people aid equipments.

  • Video adaptation in response to dynamic resource conditions and user preferences is required as a key technology to enable universal multimedia access (UMA) through heterogeneous networks by a multitude of devices In a seamless way. Although many adaptation techniques exist, selections of appropriate adaptations among multiple choices that would satisfy given constraints are often ad hoc. To provide a systematic solution, we present a general conceptual framework to model video entity, adaptation, resource, utility, and relations among them. It allows for formulation of various adaptation problems as resource-constrained utility maximization. We apply the framework to a practical case of dynamic bit rate adaptation of MPEG-4 video streams by employing combination of frame dropping and DCT coefficient dropping. Furthermore, we present a descriptor, which has been accepted as a part of MPEG-21 Digital Item Adaptation (DIA), for supporting terminal and network quality of service (QoS) in an interoperable manner. Experiments are presented to demonstrate the feasibility of the presented framework using the descriptor.
