Since the mid of 1970's, the construction of infrastructure has been booming and accelerating to keep up with rapid economic growth. Fast achievement of most construction activities has caused unfavorable effects of civil petitions associated with damages and nuisances due to last hasty works. it is well known that the falling down of Sungsoo bridge and the collapse of Sampoong department and other structures have occurred because of the construction not conforming with the specification, and thereby incurred enormous loss of life and property. Now a days. a periodic inspection and maintenance have been strongly interested on aged RC structures, of repair and reinforcement technique in the country, most repairing and reinforcing works have been performed on the basis of the guidance of few experienced local company in this field.

Measurement of lung function is an integral component of respiratory physiology and of clinical assessment of lung diseases in school age children and adults. Pulmonary function test of infants and children under the age of 2 years have now been standardised and are being used both in research and as an adjunct to clinical management. By contrast, until recegntly, children of preschool age, i.e. between 2-6 years represented a major challenge for pulmonary function test assessment, this particular period commonly being referred to as the 'dark ages' of Pediatric Pulmonology. Measurement of lung function in preschool-aged children is now feasible. However, much work remains to be done in standardizing how these tests are performed, and in understanding the most appropriate role for the various tests in the study of growth and development of the respiratory system and in the clinical management of children in this age group. As the field develops and the knowledge of respiratory physiology in this age group expands, investigation of different and more appropriate algorithm use in preschool children, together with development of more appropriate reference data, may result in improved disease discrimination.

The health screening and promotion is an emerging field of clinical preventiemedicine and is proved to be effective for reduction of diseaseprevalence, particularly life-style related diseases in aged population. However, the goal of perodic health screening can be achieved by a reliable health screening that largely depond on the quality of tests. Various tests including ultrasonography, endoscopy, CT and automated blood analyzers are used in health screening. Thesescreening tests are usually sensitive, but not specific to the presence of diseases. It meams the tests produce more false positive results, that demand eztra-expenses for the confirmation of disease. Promising screening tests should be sensitive as well as specific. However, it is not easy to maintain the quality of laboratory tests, because it is affected by various factors, such as instruments, reagents, laboratory methods and human factors. This review focuses on internal and external quality control of laboratory tests and quality management of health screening services to obtain reliable test results.

Many of aged and damaged concrete structure have been revitalized with composite reinforcement. Flexural behaviors of composite-patched concrete specimens are characterized by high-sensitivity moire interferometry. The three-mirror, four-beam interferometry system and a compact loading system are used for obtaining singe patterns representing whole-field contour maps of in-plane displacements. It is seen from the calibration test for the loading system that the measured bending displacement is in excellent agreement with the displacement calculated by the beam theory. The crack opening displacement as well as the bending and the horizontal displacement fur the notched and unnotched specimen are investigated. The results also show that the notched specimen reinforced by a composite sheet has sufficient stiffness and strength compared to the original concrete specimen.

To guarantee 20-25 years to the lifetime of the PV modules without failure, reliability test of the module is very important. Field-aged test of the outdoor environment is required. However, due to time constraints, accelerated testing is required to predict the lifetime of PV modules and find causes of failure. Failure is caused by many complex phenomena. In this study, we experimented two accelerated tests about corrosion and fatigue, respectively. First, temperature cycling test for fatigue were tested and Coffin-Manson equation was analyzed. Second, damp heat test for corrosion were tested and Eyring equation were analyzed. Finally, using two-mode failure model, we suggest a new lifetime model that analyze the phenomenon by combining two kinds of data.

As a part of stringent emission regulations, OBD on a converter is requested by EU and CARB. It demands that MIL is light-on to inform the failure to the driver when the converter is failed in its function. Usually dual oxygen sensor method is used for converter OBD. For this, detail methods, like amplitude ratio, time delay and frequency ratio methods are adapted for vehicle application. Actually, the cars produced later than MY94 for US market are using one of these methods. In this study, OSCs of converters are investigated with an absolute measuring method. The converters are aged with a furnace aging, an engine bench aging and vehicle aging method to represent various aging condition in field applications. An OBD index that is used for TLEVs regulation is also investigated to find a relation between two parameters. The relations of these parameters with THC emission on vehicle are evaluated.

The growing population of the elderly who have diverse health needs is receiving more attention from the health promotion field. This paper describes some of the findings of quantitative study into the health function of Korean immigrant elderly living in Washington State of Northwest America. One hundred-two community-dwelling Korean immigrant elderly, aged from 65 to 93 with a mean 77.97 years, were interviewed with a structured questionnaire to report their health function defined in three domains; perceived health status, physical functioning, and psychosocial functioning. The main results of the study were identified: (a) Overall, Korean immigrant elderly's perceived health status and physical functioning were good, but psychosocial functioning was poor; (b) Elderly with higher health functioning scores perceived better health status. Data indicates that health functioning measures are good indicators of the degree of perceived need for immigrant elderly. The paper argues that the understanding of physical and psychosocial functioning of elderly is vitally important in the provision of health care.
