Purpose In this study, We observed the recovery process in the ability to move in the hind limbs of the rats whose spinal cord injuries were treated by Radix acouniti(RA). The purpose of this study is to see the effects of Radix acouniti(RA) water extract on the contraction of rat's spinal cord injury. Procedure First, the rats were subjected to hemisectional spinal cord injuries by a scalpel blade. Those rats, then, were divided into three groups: Sham operated rats group and the experimental group, which received the Radix acouniti(RA) water extract, and the control group, which had no treatment. Their recovery in the ability to walk was observed by the Open Field Test (OFT) for 14 days after the injuries. Method The OFT was applied at four points: the hip, knee, ankle joint, and the tail. Each joint was given a movement rating of from 0 to 3, depending on the amount of movement. A movement rating of 0 designates no movement, a 1 designates slight movement, a 2 designates increased movement, and a 3 designates active movement. Slight movement is defined as a joint displaying less than or equal to 30% of that joint range, increased movement is displaying less than or equal to 60% of that joint's range, and active movement is greater than or equal to 90% of that joint's range. Tail movement is also graded on a scale of 0 to 3. A rating of 0 indicates that the tail is down 100% of the time, one of 1 indicates that the tail is down more than 10%, one of 2 shows that the tail is down less than 50% but more than 10% of the time, and one of 3 shows that the tail is down less than 10% of the time. All four ratings were added together and then averaged to arrive at a single score. Results The sham group which did not go through spinal cord injuries showed near normal results on all 3 joints and tail from right after the operation, which one would expect. The RA oral application group showed more effective recovery of movememt function than the control group around 4 days after the spinal cord injuries. However, after 14 days, both groups displayed almost the same degree of movement recovery. The results of this study are summarized as follows: 1. After 14days the spinal cord injuries, movement was recovered in sham operated group, control group, and experimented group in the hip, the knee, the tail and then the ankle of rats, in that order. 2. Around 7 days after the spinal cord injuries, the experimental group proved the effectiveness of the therapy in terms of movement recovery. 3. The level of ALT, ALP, AST in RA treated group was slightly increased. 4. The level of BUN and creatinine in RA treated group was slightly increased. The above results indicate that RA therapy at an early stage can bring about better movement recovery in patients with spinal cord injuries from traffic accidents or industrial disasters. But there is apparent side effect of RA on clinical, therefore the study on this should be continued.

Physical inactivity may an important outcome in the prognosis of breast cancer. Physical activity levels decrease significantly for breast cancer patients following the treatment and remain low after oncology treatment is completed. The aim of this study was to determine physical activity levels and to examine associations among physical activity, comorbidity, functional capacity, peripheral muscle strength, and psychosocial status in breast cancer patients. Forty breast cancer survivors were included in this study. Demographic and clinical characteristics were recorded. Physical activity was assessed with a short form of the International Physical Activity Questionnaire (IPAQ). We defined comorbid diseases according to the Charlson Comorbidity Index (CCI). Functional capacity was evaluated with a six-minute walk test (6MWT). Peripheral muscle strength was measured for quadriceps femoris muscle with a hand-held dynamometer. Psychosocial status was measured with the Hospital Anxiety Depression Scale (HADS). Forty percent of patients were inactive. The IPAQ total score was significantly related with quadriceps muscle strength (r=0.492; p<0.001) and HADS depression score (r=0.341; p<0.05). Marked correlations were also observed between IPAQ walking score and quadriceps muscle strength (r=0.449; p<0.001), HADS depression score (r=0.341; p<0.05), and CCI (r=-0.433; p<0.001). The CCI score was also markedly associated with quadriceps muscle strength (r=-0.413; p<0.001). 6MWT distance was not significantly correlated with any of the parameters. Regression analyses revealed that psychosocial status and peripheral muscle strength were significant predictors of physical activity estimated with the IPAQ short form and when combined, they explained 35% of the variance. Comorbidities, peripheral muscle strength and psychosocial status partially explain the variability of physical activity level in breast cancer survivors. These results suggest that physical inactivity contributes to worsening health in breast cancer survivors.

Four experiments were carried out under farmer's field conditions to determine economic threshold levels of major rice pests aad attempt a reduction in the number of insecticide applications. In the experiments were included check treatments, insecticide schedules representing the official recommendations to farmers, and several corrective treatments. A careful record was kept of insect pest densities and disease incidence. i) In the north at Suweon and Icheon where Chilo suppresalis. (Walk.), the striped rice borer, was active in the first generation, no significant yield differences were obtained between plots receiving several insecticide applications and those left totally unprotected. The mean yields were high (5.2-7.6t/ha). ii) First generation borer activity rising to $8.6\%$ injured tillers was below the economic threshold since no yield reduction was recorded in either japonica varieties or the high-yielding Tongil variety. iii) Evidence was obtained thst berer damage was made good by replacement of infested tillers (compensatory growth), C. suppressalis populations were always low in the second generation. iv) The experimental results obtained at Suweon and Icheon do not justify the present official recommendations of 6-7 pesticide applications. v) further south at Iri a substantial yield reduction occurred due to an early outbreak of stripe disease transmitted by Laodelphax striatellus (Fallen), the small brown planthopper; a mean of 1-2 individuals/hill was recorded immediately after transplanting. C. suppressalis probably contributed to this yield reduction. vi) Several applications against the vector failed to prevent the rapid spread of stripe to the susceptible variety in the Iri experiment: in surrounding fields the resistant Tonsil varivety was ralatively unaffected. vii) Pests of lesser importance were Nephotettix cinctieps (Uhler), Nilaparvata lugens (Stil), Sogatella furcifera (Horv..), and leaf miners.

Water leak detection system is a system based on wireless sensor networks(WSNs) which detect a leak on water supply, localize the leak position and finally inform a water management center. A traditional leak detection method is to use experienced personnel who walk along a pipeline listening to the sound that is generated by the leaks and their effectiveness depend on the experience of the user. Also making more successful detection, it should be processed at middle of the night when people do not use water, as the result users have to operate the leak detection system at midnight. In this paper, we propose a new method for the water leak detection system based on the WSNs and describe it in detail. Leak detection devices which detect a leakage of water transmit and receive the result of water leak detection with each other by configuring WSNs to improve reliability of the detection result. Also, we analyzed the sound from water flowed in pipeline, proposed the pre-signal processing to separate a leakage sound from noisy sound. And lastly, It is especially important to make a time synchronization with water leak detection devices that are installed on the pipeline, we used 1PPS(1 Pulse Per Second) signal generated by GPS, therefore we could get a precise time synchronization. The proposed system set up in Namyangju and performances were evaluated.

Background: The causes of exertional desaturation in patients with COPD can be multifactorial. We aimed to investigate factors predict exertional desaturation in patients with moderate to severe COPD. Methods: We tested 51 consecutive patients with stable COPD (FEV1/FVC, $40{\pm}13%$ predicted). Patients performed a six minute walk test (6MWT). Pulse oxymetric saturation (SpO2) and pulse rate were recorded. Results: Oxygen desaturation was found in 15 subjects after 6MWT, while 36 subjects were not desaturated. Lung diffusing capacity was significantly lower in desaturation (DS) group ($62{\pm}18%$ predicted) compared with not desaturated (ND) group ($84{\pm}20$, p<0.01). However there was no statistical difference of FEV1/FVC ratio or residual volume between two groups. The pulse rate change was significantly higher in the desaturated compared with the not desaturated group. Six minute walking distance, subjective dyspnea scale, airflow obstruction, and residual volume did not predict exertional oxygen desaturation. Independent factors assessed by multiple logistic regression revealed that a pulse rate increment (odd ratio [OR], 1.19; 95% confidence interval [CI], 1.01~1.40; p=0.02), a decrease in baseline PaO2 (OR, 1.105; 95% CI, 1.003~1.218; p=0.04) and a decrease in lung diffusing capacity (OR, 1.10; 95% CI, 1.01~1.19; p=0.01) were significantly associated with oxygen desaturation. Receiver operator characteristic (ROC) analysis showed that an absolute increment in pulse rate of 16/min gave optimal discrimination between desaturated and not desaturated patients after 6MWT. Conclusion: Pulse rate increment and diffusion capacity can predict exertional oxygen desaturation in stable COPD patients with moderate to severe airflow obstruction.

Background: A chronic obstructive pulmonary disease (COPD) assessment test (CAT) has recently been developed as a short and simple method for assessing the quality of life in COPD patients. The object of this study was to assess the usefulness of the Korean version of the CAT for assessing COPD patients in an outpatient clinic. Methods: The study included 60 COPD patients in a stable state from an outpatient clinic. The authors investigated the frequency of acute exacerbation during aprevious year through reviewing medical records. We evaluated the spirometry test, a 6-min walk distance test, and obtained the MMRC dyspnea scale, the Korean version of the CAT, and the BODE index at the time of visit. To assess the usefulness of the CAT, correlations between the CAT and other methods were evaluated. Results: The mean age of patients was $68.3{\pm}8.6$ years and 95% of patients were male. There was a significant correlation between the CAT score and $FEV_1%$ (r=-0.323, p=0.012), the frequency of acute exacerbation (r=0.292, p=0.024), the MMRC dyspnea scale (r=0.554, p<0.001), the BODE index (r=0.380, p=0.003), and 6 MWD (r=-0.372, p=0.004). The mean CAT score increased according to the GOLD stage (stage 1, $10.7{\pm}4.5$; stage 2, $13.1{\pm}7.9$; stage 3, $16.3{\pm}6.2$; stage 4, $16.5{\pm}14.8$; p=0.746). Conclusion: The CAT was shown to be useful for the assessment of COPD severity. Therefore, the CAT is an easily applied and simple method for assessing COPD severity in an outpatient clinic.

This studies were conducted to compare ozone sensitivity among half-sib families of Japanese red pine (Pinus densiflora S. et Z.). 90 families were exposed in walk-in type chambers to charcoal-filtered air and 100 ppb ozone for 8 hours daily, 5 consecutive months. We surveyed the foliar injury, Relative DRC (diameter at root collar) growth and relative dry weight after fumigation. After 5 months of exposure, foliar injury ranged from 1.9% at tolerant group to 15.2% at sensitive group. Relative DRC growth rates showed increased 12% at tolerant group, but reduced 23% at sensitive group. Total dry weight increased 17% at tolerant group, otherwise reduced by 33% at sensitive group, relative to the control. The root biomass showed more sensitive than the other part biomass. On the basis of the results of these screening studies, families Kangwon 04, 16, 26, 27 and 73 were determined to be tolerant; Kangwon 40, 52, 83, Gyeonggi 01 and Gyeongbuk 20 to be sensitive to ozone. Considerable genetic variation in ozone responses occurred, as shown by differences in sensitivities among families and among groups. These results indicate that tolerant groups of P. densiflora exhibited a high degree of resistance to ozone pollution injury.

The social understanding of the rehabilitation and welfare work for the handicapped children is nearly devoid in Korea. Especially the medical rehabilitation or nursing for them is left ign. ored as well as the literature preferential to this study is wanted. For the purpose of conducting the study of this thesis Sam Yook Children's Rehabilitation Center, Inc. and Crippled Children's Center, Yonsei University Medical center sampled out; covering three months from Aug. 1 to Oct. 30, 1973, the problems of children's rehabilitation, the characteristics of the children, the medical rehabilitation, nursing, education, and vocational rehabilitation were interviewed and widely grasped. This thesis aimed at developing the rehabilitation, the professional nursing and especially aimed at contributing to the improvement of welfare for the handicapped by analysing, observing the result of this study. The result is as follows: 1. Sam Yook Children's Rehabilitation Center, Inc. has, since its establishment, contributed to the advancement of the crippled children and its purpose consists in implementing services, medical rehabilitation, nursing, education and vocational training. Crippled Children's Center, Yonsei University Medical Center is, being based on Christianity, aiming at the medical treatment and education for the crippled children. 2. All of the children admitted in the children's rehabilitation centers are the crippled children. The ratio of boys io girls is three to two. Boys are more than girls. Orphan formed 55.2 per sent of them. About 60 per cent of them is receiving medical attention free of charge. But there is no orphan in Crippled Children's Center, Yonsei University Medical Center. 3. 15.7 per cent of them have received the previous medical attention before their admitting in the centers; in Sam Yook Children's Rehabilitation Center 8.6 percent, Crippled Children's Center, Yonsei University Medical Center 50 percent; there is remarkable difference between the two. 4. On the standpoint of period of being in the centers, the children who have been over three years in Sam Yook Children's Rehabilitation Center formed 48.7 per cent; in Crippled Children's Center, Yonsei University Medical Center 2.6 percent; there is also considerable difference between the two; they couldn't discharge from the centers owing to the economic conditions and being orphan. 5. Among the diagnosis of the crippled children, poliomyelitis formed highest 51.7 percent of them ; cerebral palsy formed 30 percent secondly in order. Environmental factors (67.8 percent formed about three times of congenital factors (23.7 percent). 6. The children who are capable of doing independently activity of daily living formed 87.9 percent; 73.2 percent can walk about 300 m by wearing brace and so on. The ratio of wearing brace or leg prosthesis formed 47.4 per cent: crutch 44.3 per cent. The medical rehabilitation service and education for the crippled, are comparatively well carried out. But it is desired to improve and cultivate the vocational training, vocational guidance and special nursing to the insufficiency of their implementation. In the tendency that the rehabilitation and welfare for the handicapped are today emphasized, International Handicapped Rehabilitation Association, declaring that 1970s are the decade of rehabilitation, urged to improve positively the policy of rehabilitation and welfare for the handicapped. But here in korea the handicapped, being the object of social prejudice, ignorance, disdain lives in obscurity. Therefore the government or the community should draw up countermeasure on social under-standing, financial support, and rehabilitation services for the handicapped as well as should endeavor to make them participate in social activities as the productive total- person though they are physically imperfect.

This study aimed to explore the direction of development of agricultural safety and health system in Korea based on experience on Farmers' Occupational Health Services (FOHS) of Finland. In Finland additional and specialized Occupational Health Services (OHS) for self-employed farmers were developed and have been conducted by municipal primary health care centers with cooperation of National Centre for Agricultural Health (NCAH) of Finnish Institute of Occupational Health, Social Insurance Institute (SII) and Farmers' Social Insurance Institution (FSII). Based on the study, in order to activate the FOHS in Korea, the analysis results could suggest the development of four prerequisites. Firstly, center for farmers' safety and health like NCAH, which conducts surveillance on health and safety status, standardization of intervention contents and epidemiological research is needed in national institution. Secondly, development of evaluation tools with lower cost and difficulty like walk-through survey for checking status of systems of safety in the farms is needed. Thirdly, farmers' occupational health insurance which will be initiated on near future should be connected to preventive intervention programs like FOHS. Lastly, training and qualification of more local occupational health experts and units is needed.

This study purposes to conduct visual feedback and body posture control training on stroke patients with pusher syndrome in order to reduce their pusher syndrome. This study also examines changes resulting from the training and applies the guidelines necessary for documentation of patient/customer management. The participant for this study was one patient with pusher syndrome. The study progressed from a medical examination of the subject followed by evaluation, diagnosis, prognosis, intervention and treatment plan, and finally re-examination in order of precedence. Problems in the participant's functional activities, difficulties in changes from sitting postures into standing postures, and maintaining standing postures were determined as primary restrictions on activities and the improvement of these activities was set up as a goal through discussions with the patient. Interventions were mainly implemented to reduce the pusher syndrome with visual feedback provided using mirrors and exercises focusing on leaning in order to maintain posture while sitting. Changes from supine postures to sitting postures and the degree of changes in maintaining standing postures were compared between before and after the intervention by measuring times in the same environment and the degree of pusher syndrome was measured using the SCP tool. The process of this clinical practice was documented. The SCP score that indicates the degree of changes in the participant's pusher syndrome changed from 3.75 points to 0.8 point indicating a decrease in pushing. Among functional activities, posture changes from sitting postures to standing postures and maintaining standing postures were improved. In addition, since the patient could maintain standing postures, the patient could walk indoors. In this case study, mirrors and body posture control training used as interventions to relieve pusher syndromes can be easily applied in clinics to examine the form of functional recovery. The results indicated that these intervention methods were effective and thus it is thought that the results can be used as basic data to utilize these intervention methods diversely. In addition, the documentation of patient/client management was applied as actual documentation in Korean and based on the results, we could show decision making processes for patients' functional goals and objectively explain problems, prognoses and changes made through the interventions.
