Certification flight test is very risky and there are many hazards. Because the flight test is performed with the aircraft, that is safety and flight characteristics are not proven. And the test items and conditions are critical. If there is loss of aircraft during certification flight test, the certification program, development period can be delayed. Therefore, maintaining safety of the aircraft during flight test is very important. There are not much flight test experiences in Korea. However, developed nations has long history of flight test and experiences of flight test accidents. Based on these experiences, they has developed systematic management methods for the flight test safety. In this study, I would like to introduce safety management and risk assessment of the certification flight test.

PURPOSES : The purpose of this study is to suggest a specific investigation guideline to decide priority of repairing old concrete pavements that pile up substantially. METHODS : In this study, a principle of division of homogeneous sections was proposed to reflect the characteristics of the pavement reasonably in the specific investigation results. In addition, a checklist and guideline of field investigation were suggested for the old concrete pavement sections, which require inspection toward their durability and structural performance. Furthermore, the items of laboratory test necessary to the old concrete pavement were suggested based on the existing laboratory test considering characteristics of the old concrete pavement. The present condition of the old concrete pavement could be analyzed by the test results. RESULTS : A method of division of homogeneous sections suitable for the specific investigation of the old concrete pavement was suggested. The proportions of distress severity of pavement sections were compared by distress type to figure out the present state of the old concrete pavement. Scaling, durability cracking (or alkali-silica reaction), and longitudinal spalling were selected as the most severe distress types. The detailed positions of the sections were also suggested. The checklist of the specific investigation was categorized by field survey and laboratory test, and its evaluation criteria were proposed. The three types of the sections of durability cracking (or alkali-silica reaction), bridge connection, and asphalt overlay were selected as the sections of the field survey. The compressive strength, void structure, and chloride penetration depth were suggested as the items of the laboratory test. CONCLUSIONS : A fundamental level of the guideline was suggested in this study to resolve the problem of old concrete pavement. Appropriate guidelines related to the repair of the old concrete pavement should be provided by performing additional research efforts.

In 1991, the Ministry of Health & Social affairs adopted a nationwide service program for neonatal screening of phenylketonuria, galactosemia, maple syrup urine disease, homocystinuria, histidinemia & congenital hypothyroidism for newborns delivered from low class pregnant women registered in health centers. Government decreased the test items from six to two, PKU & congenital hypothyroidism to increase test numbers with same budget from 1995. Government decided to test PKU & hypothyroidism for all newborns from 1997. 78 laboratories wanted to participate for neonatal screening test in 1999. Government didn't decide laboratory center for a certain district and placed responsibility on free competition. Government are planning to test 573,000 newborns from 1998, Government decided to screen 6 items PKU, congenital hypothyroidism, maple syrup urine disese, homocystinuria, galactosemia and congenital adrenal hyperplasia from 2006. 17 laboratores are participating now. The cost of screening test is supported by both the federal government and local government on a 40-60 basis. In case a patient with an inherited metabolic disease is diagnosed by screening of government program, special milk is provided at government's expense. Interlaboratory quality control was started 6 times a year from 1994. According to the government project, 3,707,773 newborns were screened. 86 PKU, 718 congenital hypothyroidism were detected. So incidence of PKU is 1/43,114 and congenital hypothyroidism is 1/4,612. Maeil dairy company produced new special formula for PKU, MMA and PA, MSUD, urea cycle disorder, homocystinuria, isovaleric acidemia from Oct. 1999. The cost benefit of performing screening procedures coupled with treatment has been estimated to be as high as 1.77 times in PKU, 11.11 times in congenital hypothyroidism than cost without screening. We are trying to increase the budget to test all newborns for Tandem mass sereening & Wilson disease from 2008. Now it is a very important problem to decrease laboratory numbers of neonatal screening in Korea. So we are considering 4-5 central laboratories which cover all newborns and are equipped with tandem mass spectrometer & enzyme immunoassay for TSH, 17OHP & enzyme colorimetric assay for galactose.

The purpose of this study was to investigate the effect of balance training with upper extremity exercise on the improvement of balance performance in people who have had a stroke. Eighteen candidates who have all experienced a stroke, were living in Dong-Gu, Ulsan and were participating in a community based rehabilitation program, have been included in this study. The program was conducted three times weekly, 1 hour per session, for 7 consecutive weeks. Subjects were tested with 7 m and 100 m Timed Gait Test (sec), Timed Get Up and Go Test (sec), Functional Reach Test (cm) and 5 items of Berg's Balance Test at pre-training and post-training. Total balance index and balance ratios were measured by K.A.T. 3000. The balance training program performed by sitting on a chair and gymnastic ball and standing on stable and unstable surfaces during upper extremity exercises such as Proprioceptive Neuromuscular Facilitation (PNF) upper extremity pattern, picking a ball up from floor, throwing and catching it. After seven weekends of balance training, subjects showed a significant difference in balance test results. The exceptions were three items of Berg's Balance Test (p<.05). Balance index score and affected and unaffected side balance ratio had a larger improvement than pre-training (p<.05). The result of this study showed that intervention of this balance training program could improve the balance performance in people who have had a stroke.

The purpose of this study was to develop a tool to assess the powerlessness and to measure the powerlessness of elderly. From the result of pre-test, twenty seven items were finally selected to survey the elderly's powerlessness. The questionnaires on the elderly's powerlessness were drafted so that such tool may be evaluated in accordance with the four point Likert Scale. The number of subjects is 1,150 with ages of 60 years or more and who live in a large city, a small and middle-sized city and a rural area. The subjects of the test and retest were 85 elderlies. Collected data were analyzed by utilizing SAS program with Cronbach's $\alpha$ and Pearson's correlation, factor analysis method and known group techniques, descriptive statics, t-test and ANOVA. The results from this study were summarized below:1. When the factor analysis method was applied for validity, the tool for powerlessness of elderly was separated into 5 factors: loss of self-confidence to deal with physical, emotional, social aspects of life; expulsion by others from meaningful human relate; perception that life is meaningless and time passes quickly; falling behind young people; being rejected by other people, having no influence on others. An application of the known group technique showed a significant difference with the result of the degree of elderly's powerlessness tools developed by the two groups, with illness and without. 2. In testing reliability, it was found that coefficient of test-retest was .9435(P<.0001) when the test-retest method was used as a test of stability, and that the alpha coefficient of internal consistency was .9141 over all items within the tool of elderly's powerlessness 3. In powerlessness of elderly, total mean is 2.8493. And in factor of powerlessness, the highest factor is falling behind young people (M=3.1713), the lowest factor is loss of self- confidence to deal with physical, emotional, social aspects of life(M=2.6080). 4. The results from the test for the degree of powerlessness, according to the subject's demographic variables, showed that there were significant differences between age, sex, marital status, educational level, religion, possession of house, job, monthly pocket money, health status, illness and a place of residence.

PURPOSE: The purpose of this study was to compare sitting balance and coordination spastic cerebral palsy in children using the Korean version of Trunk Impairment Scale (K-TIS) as well as to provide basic data about effective postural control treatment for clinicians handling these two types. METHODS: The K-TIS was measured in 29 children diagnosed with diplegic and quadriplegic cerebral palsy (18 with diplegia and 11 with quadriplegia). The average and standard scores of the children's K-TIS subscales and items of the two groups were measured. The two groups' subscales and items were analyzed by using the Mann-Whitney U test. RESULTS: Static sitting balance, dynamic sitting balance, coordination, and total score for children with diplegia were statistically high (p<.05). For all items under static sitting balance, the score for children with diplegia was higher. The first differences in the repeated items of dynamic sitting balance and coordination area that rotates between the upper and lower body were presented. CONCLUSION: The difference in balance and coordination in sitting positions is exhibited in children with diplegia and quadriplegia. For children with spastic quadriplegia, treatments should focus on static sitting balance and coordination, together with a focus on dynamic sitting balance and coordination.
