Regardless of the age, Low back pains are appeared to the highest occurrence ratio and every one meet with the disease once at least through life. In order to treat a pain, therefore, it make a accurated treatment program by the accurated a cause and evaluation and can expected to effects of treatment. In order to do the perfected physical therapy, futhermore, it is nessessary more systematic studies not a cause and physical diagnosis but pathological aspects.

Objectives: The aim of this study was to investigate whether a medium to high degree of total physical activity and indoor physical activity were associated with reduced all-cause and cardiovascular mortality among elderly Korean women. Methods: A prospective cohort study was done to evaluate the association between physical activity and mortality. The cohort was made up of elderly (${\geq}65$ years of age) subjects. Baseline information was collected with a self-administered questionnaire and linked to death certificates retrieved from a database. Cox proportional hazard models were used to estimate the hazard ratios (HRs) with 95% confidence interval (CI) levels. Results: Women who did not suffer from stroke, cancer, or ischemic heart disease were followed for a median of 8 years (n=5079). A total of 1798 all-cause deaths were recorded, of which 607 (33.8%) were due to cardiovascular disease. The group with the highest level of total physical activity and indoor physical activity was significantly associated to a reduced all-cause mortality (HR, 0.60; 95% CI, 0.51 to 0.71 and HR, 0.58; 95% CI, 0.50 to 0.67, respectively) compared to the group with the lowest level of total physical activity and indoor physical activity. Additionally, the group with the highest level of total physical activity and indoor physical activity was significantly associated to a lower cardiovascular disease mortality (HR, 0.53; 95% CI, 0.40 to 0.71 and HR, 0.51; 95% CI, 0.39 to 0.67, respectively) compared to the group with the lowest level of total physical activity and indoor physical activity. Conclusions: Our study showed that regular indoor physical activity among elderly Korean women has healthy benefits.

Falls are the most serious health problems in elderly population. They are a major cause of premature death, physical injury, immobility, psychosocial dysfunction, and nursing home placement. To reduce the alarming rate of falls and related excessive mortality and morbidity, efforts must be made to detect persons at risk of falling and to prevent or reduce the frequency of falls. To facilitate such approaches, it is essential to find the cause of falling (and under what conditions) of the elderly and the factors that are associated with risk of falling. This study was aimed at designing interventions that minimize risk of falling by ameliorating contributing factors while maintaining or improving patient's mobility.

Falls are a leading cause of injury, disability and death among people older than 65. Even without injury, falls cause a loss of confidence that results in reduced physical activity, increased dependency and social withdrawal. Fall prevention in the eldery people is a multifaced task that includes both the identification of risk factors and their modification strategies. Fall risk factors have been identified as both intrinsic and extrinsic. Intrinsic factors are those related to the physical and cognitive function of the person. Extrinsic factors are those which are included in the environmental hazards of everyday life. Combinations of interventions aimed at modifying both intrinsic and extrinsic risk factors can result in significant fall prevention in the geriatric population. This article selectively reviews the literature reporting exercise intervention to improve strength, balance and mobility.

Functional stability is dependent on integrated local and global muscle function. Movement dysfunction can present as a local and global problem, though both frequently occur together. To good understand how movement induces pain syndrome, the optimal actions and interaction of the multiple anatomic and functional systems involved in motion must be considered. Minor alterations in the precision of movement cause microtrauma and, if allowed to continue, will cause macrotrauma and pain. These alteration of the movement result in the development of compensatory movement and movement impairment. Muscle that become tight tend to pull the body segment to which they are attached, creating postural deviation. The antagonistic muscles may become weak and allow postural deviations due to lack of balanced support. Both hypertonic and inhibited muscles will cause an alteration of the distribution of pressure over the joint(s) that they cross and, thus, may not only result from muscle dysfunction, but produce joint dysfunction as well. Alteration of the shoulder posture and movement dysfunction may sometimes result in compression of neurovascular structures in the shoulder and arm. There is a clear link between reduced proprioceptive input, altered motor unit recruitment and the neurovascular compression. This report start with understanding of the impaired alignment, movement patterns and neuromuscular compression of the shoulder girdle by movement impairment to approach method of the movement dysfunction.

To find out the actual status of treatment of physically handicapped who were stayed of home, 320 physically handicapped persons were selected among total 6,264 physically handicapped registered in Taejon city, surveyed from January 1st to March 30, 1997. Following are the results ana lysed of collected data from 201 samped persons. 1. For the cause of physically handicapped, 36.3% was congenital, 26.9% was cerebralvascular acciednt(CVA). and 14.9% was infectious diseases and others in that orders. The must frequest cause of below 20 years age group was congenital cause, but that of $20{\sim}30$ years age group and $40{\sim}50$ years age group were accident and CVA repectively. 30.0% of respondents caused by infection and others earned household living expenses. Household living expenses were higher among the respondents caused by congenital cause but those were lowest in the accidental couse group. Handicap durations were longer in the accidental cause group and infections and others group than the congenital cause group and CVA group. 2. 54.7% of studied handicapped were under treatment. But 36.3% of them were stopped treatment, and 8.9 % of them answered not treated. Most handicapped, coused by congenital and CAV, were under treatment, but most of them caused by accidental and others were stopped treatment. 3. For the medical facilities, 54.5% of them utilized welfare facility, but 25.5% utilized general hospital and 20.0% of them utilized oriental medical hospital and health centers. Congenital cause group frequently selected welfare facility for the treatment facility. But accidental cause group frequently seleced general hospitals and CVA gruop frequently selected oriental medical hospital and others. The medical cost of welfare facility, oriental medical hospitals and others were lower than that of general hospitals. 4. The proportions of under treatment were higher among yonger age higher monthly living expenses group shorter handicapped duration groups, congenital cause group and handicap grade II group. But that of stop treatment were higher among congenital cause group, infectious and others cause group, and handicap grade I & then III group. 5. For the feelings satisfacion about medical treatment, only 35.3% of under treated group responed satisfation. 55.5% of them responded so-so, but 9.1 % responed dissatisfaction. The proportion of satisfaction was higher among shorter handicap duration group.

Although previous studies revealed the association of physical activity with mortality rate, it is unclear whether there is a linear trend between physical activity and mortality rate. In this study, the association of physical activity with the risk of all-cause mortality was analysed using Cox's proportional hazard model for a cohort of 14,204 healthy Korean men aged 40-59 years followed up for 4 years(Jan. 1993-Dec. 1996). Physical activity and other life style were surveyed by a postal questionnaire in December 1992. Total of 14,204 subjects were grouped into quartiles by physical activity. Using death certificate data, 123 deaths were identified. The second most active quartile had a lowest mortality .ate with relative risk of 0.44(95% C.I. : 0.23-0.84) compared with most sedentary quartile, showing a J-shape pattern of physical activity-mortality curve. By examining the difference in proportion of cause of the death between most active quartile and the other quartiles, there was no significant difference of proportional mortality from cardiovascular deaths, cerebrovascular deaths or deaths from trauma. The covariates were stratified into two group between which the trend of RR was compared to test the effect modification. There was no remarkable effect modification by alcohol intake, smoking, body mass index, calorie consumption, percent fat consumption. In conclusion, moderate activity was found to have more protective effect on all-cause mortality than vigorous activity and that the J-shape pattern of physical activity-mortality curve was not due to the difference of mortality pattern or effect modification by alcohol intake, smoking, body mass index, calorie consumption and percent fat consumption.

Stroke is the leading cause of adult disability and the third leading cause of adult death in the world. Stroke has an impact on the physical, psychological and social dimensions of quality of life. An increasing number of authors have reported a deterioration of the quality of life in a large proportion of patients after a stroke. Just as satisfaction with each dimension varies to everyone, the importance of each dimension also varies and does not impact equally on the quality of life. So assessment on the quality of life has to adopt a multidimentional approach and to make use of the subjective and objective indicators.

The Operation of high speed train in year 2004 bring about a great change in railroad industry. Especially in railroad construction field we have acquired great Know-how. And up to now we are building up operation skills. But the high speed train system are totally imported, so it is necessary to investigate some of the equipment based on our own environment. In case of Toughened Glass Stem Insulator, we don't have any application case in domestic and limited in abroad. So there must be some characteristic estimation. The estimation was made in three different ways. First electrical field cause, Second physical field cause and finally in circumstance cause. In Electrical field cause, amplitude and number of time for abnormal peak voltage data are collected. And in physical field cause, amplitude and trend of vibration in to the insulator are examined. And I circumstance cause, possibility of flying gravel and ice clod are investigated. Through this basic data suitability for Toughened Glass Stem Insulator using in domestic will be accumulated.
