Objectives : Most of pains are important symptoms caused by cancer transpered to spine. Harpagophyti Radix Pharmacopuncture is highly effective in reducing fever, pain, inflammation but was never used to reduce pain from cancer transpered to spine. So I intended to use Harpagophyti Radix Pharmacopuncture to control pain. The purpose of this study is to evaluate the clinical application of Harpagophyti Radix Pharmacopuncture for Bone Metastasis of Breast Cancer and Spinal Stenosis. Methods : We examined patient with Bone Metastasis of Breast Cancer and Spinal Stenosis who admitted Jaseng Korean Medicine Hospital. The patient was treated by Korean Medicine treatment and Harpagophyti Radix Pharmacopuncture. This case was assessed by Numerical Rating Scale(NRS), Oswestry Low Back Pain Disability Index(ODI), Short-Form 36 Health Survey(SF-36), ROM(Range of Movement) and Special Test. Results : In this study, the patient's pain was controlled and NRS, ODI were decreased. I could identify the improvement in life quality from the positive change of SF-36 and also found out that treatment was successful from the improvement of ROM, Special test. Conclusions : Harpagophyti Radix Pharmacopuncture with Korean Medicine treatment for Bone Metastasis of Breast Cancer and Spinal Stenosis was proved to be useful to the pain relief and function recovery, but further research should take place for clear understanding of the exact amount of dosage and safety. Moreover it must be accompanied by long term follow up research.

The environment in the ICU leads to negative changes in a patient's usual sleep pattern and so contributes negatively to the patient's health condition as compared to patients in general wards. Therefore, it is thought that an important nursing intervention would be to identify the relation between noise and sleep patterns which play an important role in illness recovery. The purpose of the present study was to explore the relationship between noise in the ICU and the sleep pattern of patients admitted to the ICU. A descriptive correlation design was used to examine the relationship. Thirty-four subjects were recruited from a Medical ICU (MICU), Surgical ICU (SICU) and Coronary Care Unit (CCU) at a large university hospital in Suwon. Data were collected from September 28 to October 31 in 1999. In the present study, noise was categorized into noise level and patients' perception of noise. The objective noise level was measured using the A-Weighted Sound Level Meter. The patients' preception of noise was measured using a self-reported questionnaire developed by the researcher. Sleep patterns in this study includes both quantity and quality of sleep. These were measured using open ended questionnaires and the 'Korean Sleep Scale A' developed by Oh, Song, Kim(1998). The data was analyzed using the SPSS-WIN to test the research question, Pearson product moment correlation coefficient was run. Ancillary analysis were conducted with demographic variables to determine their relation to the main study variables. For the ancillary analysis, t-test and one-way ANOVAs were performed. The results of the present study are summerized as follows : 1. The total mean of objective noise level (10pm-6am) was 56.2dB. The means for night time noise level in individual ICUs for the SICU, MICU and CCU, were 58.7dB, 58.6dB and 48.3dB, respectively. The total mean for patients' noise perception was 42.8 out of a maximum possible score of 76. For item means of noise perception, the one ranked highest was "conversations between doctors and nurses" (3.2). The one ranked lowest was "noise from the radio" (1.2). Regarding the degree of perception for each type of noise source, the one ranked highest was "equipment noise" (2.6), the second was "conversation between medical staff" (2.4), the third was "conversation between patients, caregivers and visitors" (2.3), and the one ranked lowest was "environment noise" (1.8). 2. Looking at quantity of sleep of ICU patients, the mean nocturnal sleep time was found to be 4.9 hours. The total mean of sleep quality for ICU patients was 21.0 out of a maximum possible score of 40. 3. The relationship between perception of noise and quantity of sleep was statistically significant(r= - .41, p<.05). The relationship between perception of noise and quality of sleep was also statistically significant(r= - .47, p<.01). The results of the study indicate that personal perception of noise is related to sleep patterns. Therefore, it is suggested that nursing interventions be developed to reduce the degree of personal perception of noise and, thus, decrease sleep pattern disturbances in patients in the ICU.

Objectives The aims of this study was to observe the effectiveness of East-West Integrative Medicine (EWIM) by analysing between EWIM estimated group and Non-EWIM eastimated group with Brain Rehabilitation Registry. Methods We divided hospitals into two groups, one is EWIM estimated group hospital (Kyeonghee university, Wonkwang university, Dongguk university) and the other is non-EWIM estimated group (Jeonnam university, Gyeongbuk university, Catholic university). Then we analysed the effectiveness of treatments retrospectively using the database of Brain Rehabilitation Registry (http://www.kbrr.or.kr/, version 1.0). Totally 293 patients were included, EWIM estimated group was 175 and non-EWIM estimated group was 118. The main outcome measurements were National Institutes of Health Stroke Scale (NIHSS), Modified Barthel Index (MBI) and Mini Mental State Examination-Korea (MMSE-K). Results Changes of NIHSS was not significant in both total patient and patient who treated over 3 weeks. MMSE-K showed positively significant difference (p=0.044) in EWIM estimated group patients who treated over 3 weeks. In case of MBI, EWIM estimated group showed more effective result and also statistically significant in both total patients and patients who treated over 3 weeks. Conclusions We patially argued that EWIM estimated group was more effective than non-EWIM estimated group in stroke patients' functional recovery. We suggested base data of EWIM in stroke patiens through this study and this could be applied future researches of developing modified EWIM system.

Thermophilic $H_2$ was produced for 1 year using a bench-scale continuous stirred tank reactor(CSTR). The CSTR was inoculated with anaerobically digested sludge after heat treatment and fed with a glucose-based medium. The reactor showed relatively short start-up period(30 days) and high maximal $H_2$ yield(2.4 mol $H_2/mol$ glucose). Keeping pH 5.0 or less suppressed methanogenic activity. Bacteria affiliated with Thermoanaerobacterium thermosaccharolyticum kept being dominant from approximately 40 days as determined by DGGE. Environmental perturbation(pH or temperature) caused the decrease of biomass concentration in the reactor and the instability of reactor performance, $H_2$ production rate and $H_2$ yield. The unstable performance was accompanied with high concentration of lactate in the effluent. Taken together, the poor recovery of CSTR after perturbations could be partly explained by low biomass concentration and/or metabolic shift of the major population in the CSTR.

Owing to recent climate change, the scale of rainfall tends to increase gradually and the risk of flooding has increased. Therefore, the importance of improving the levee management and disaster response is increasing. Levee management in Korea is carried out at the level of damage recovery after the occurrence of damage. Therefore, it is necessary to develop a technology for predicting and managing the levee safety with proactive river management. In this study, a method to estimate the safety against erosion and overflow was suggested. A map of levee safety that can be used as basic data is presented by displaying the levee safety on the map. The levee erosion safety was calculated as the ratio of the internal and external force for each shore type. The levee overflow safety was calculated as the ratio of the maximum conveyance and design flood. The maximum conveyance was a discharge when the level of the river was equal to the level of the levee crown. The levee safety was classified into 5 grades: very safe, safe, normal, dangerous, and very dangerous. As a research area from downstream of Nam River Dam to Nakdong River Junction, the levee safety against erosion and overflow was estimated for all levees and all cross-sections of the river. The levee safety was displayed on a map using GIS. Through the levee safety map as a result of this study, the levee safety can be observed intuitively. Using the levee safety map, a maintenance plan for a river can be easy to build. This levee safety map can be used to help determine the priority of investment for efficient budget used.

Effect of electrode spacing on the performance of microbial electrolysis cells(MECs) for treating sewage sludge was investigated through lab scale experiment. The reactors were equipped with two pairs of electrodes that have a different electrode spacing (16, 32 mm). Shorter electrode distance improved the overall performance of MEC system. With the 16 mm of electrode distance, the current density was $3.04{\sim}3.74A/m^3$ and methane production was $0.616{\sim}0.804Nm^3/m^3$, which were higher than those obtained with 32 mm of electrode spacing ($1.50{\sim}1.82A/m^3$, $0.529{\sim}0.664Nm^3/m^3$). The COD removal was in the range of 34~40%, and the VSS reduction ranged 32~38%. As the current production increased, VSS reduction and methane production were increased possibly due to the improved bioelectrochemical performance of the system. Methane production was more affected by current density than VSS reduction. These results imply that the reducing the electrode spacing can enhance the methane production and recovery from sewage sludge with the decreased internal resistance, however, it was not able to improve VSS reduction of sewage sludge.

Immunization of layers against Salmonella gallinarum(S.G.) which causes fowl typhoid resulted in production of anti-S.G. IgY rich eggs. Water soluble fraction was obtained from egg yolk using various gum solutions such as 0.1%(Sigma C-3889) λ-carrageenan; 1% and 2% cold water soluble carrageenan; 1% and 2% hot water soluble carrageenan; and 1% cold water soluble carrageenan with 1% hot water soluble carrageenan. Among them, λ-carrageenan 0.1% treatment showed a high recovery rate, possessing high IgY contents. In the range of pH 5-9, more than 70 percent of IgY was existent. Moreover, Anti-S.G. IgY was relatively heat-stable. This study revealed that immunoglobulin against fowl typhoid could be produced successfully by layers and the IgY was sustainable to further processing due to its pH and heat stability. IgY is promising to be utilized for prevention and treatment of fowl typhoid in industrial scale.

Purpose: The lateral epicondylitis is very common around elbow joint. We investigated the effectiveness of arthroscopic treatment. Materials and Methods: From Oct. 2002 to Feb. 2006, a total of 14 patients who were diagnosed with lateral epicondylitis and treated with arthroscopy were used in this study. The average symptom durations before receiving treatment was 27.3 months (9 to 47 months) and the average follow-up periods was 13.6 months (8 to 22 months). Results: The mean preoperative VAS scores was 8.3 (7 to 10 points) and the mean postoperative scores was 1.6 (0 to 4 points). The lesions of extensor carpi radialis brevis were classified using Baker's classification system. Type 1 lesion was found in 7 cases, type 2 in 4 cases, type 3 in 1 case Patients were able to return to their normal life style by 12.3 days (6 to 27 day). Conclusion: The Clinical outcomes of patients who received arthroscopic treatment were found to be good. Patients experienced lesser pain, and shorter recovery time. Therefore, when conservative treatment is ineffective in treating the lateral epicondylitis, arthroscopic treatment is considered af another option available for patients.

PURPOSES : This study examines the performance changes of road networks according to the strength of a disaster, and proposes a method for estimating the quantitative resilience according to the road-network performance changes and damage scale. This study also selected high-influence road sections, according to disasters targeting the road network, and aimed to analyze their hazard resilience from the network aspect through a scenario analysis of the damage recovery after a disaster occurred. METHODS : The analysis was conducted targeting Sejong City in South Korea. The disaster situation was set up using the TransCAD and VISSIM traffic-simulation software. First, the study analyzed how road-network damage changed the user's travel pattern and travel time, and how it affected the complete network. Secondly, the functional aspects of the road networks were analyzed using quantitative resilience. Finally, based on the road-network performance change and resilience, priority-management road sections were selected. RESULTS : According to the analysis results, when a road section has relatively low connectivity and low traffic, its effect on the complete network is insignificant. Moreover, certain road sections with relatively high importance can suffer a performance loss from major damage, for e.g., sections where bridges, tunnels, or underground roads are located, roads where no bypasses exist or they exist far from the concerned road, including entrances and exits to suburban areas. Relatively important roads have the potential to significantly degrade the network performance when a disaster occurs. Because of the high risk of delays or isolation, they may lead to secondary damage. Thus, it is necessary to manage the roads to maintain their performance. CONCLUSIONS : As a baseline study to establish measures for traffic prevention, this study considered the performance of a road network, selected high-influence road sections within the road network, and analyzed the quantitative resilience of the road network according to scenarios. The road users' passage-pattern changes were analyzed through simulation analysis using the User Equilibrium model. Based on the analysis results, the resilience in each scenario was examined and compared. Sections where a road's performance loss had a significant influence on the network were targeted. The study results were judged to become basic research data for establishing response plans to restore the original functions and performance of the destroyed and damage road networks, and for selecting maintenance priorities.

Purpose: The aim of this study is to present a retrospective review of patients who had a sudden onset of facial palsy after trauma and who underwent facial nerve decompression. Methods: The cases of 25 patients who had traumatic facial palsy were reviewed. Facial nerve function was graded according to the House-Brackmann grading scale. According to facial nerve decompression, patients were categorized into the surgical (decompression) group, with 7 patients in the early decompression subgroup and 2 patients in the late decompression subgroup, and the conservative group(16 patients). Results: The facial nerve decompression group included 8 males and 1 female, aged 2 to 86 years old, with a mean age of 40.8. In early facial nerve decompression subgroup, facial palsy was H-B grade I to III in 6 cases (66.7%); H-B grade IV was observed in 1 case(11.1%). In late facial nerve decompression subgroup, 1 patient (11.1%) had no improvement, and the other patient(11.1%) improved to H-B grade III from H-B grade V. A comparison of patients who underwent surgery within 2 weeks to those who underwent surgery 2 weeks later did not show any significant difference in improvement of H-B grades (p>0.05). The conservative management group included 15 males and 1 female, aged 6 to 66 years old, with a mean age of 36. At the last follow up, 15 patients showed H-B grades of I to III(93.7%), and only 1 patient had an H-B grade of IV(6.3%). Conclusion: Generally, we assume that early facial nerve decompression can lead to some recovery from traumatic facial palsy, but a prospective controlled study should and will be prepared to compare of conservative treatment to late decompression.
