Objectives : To examine the relationships among health promoting lifestyle, anxiety, and self-esteem for korean immigrants in New York. Methods : The study included 425 adults aged 18 and over, who were chosen from Korean church and social organizations located in New York. The data were collected from April to July, 1996 using self-administered questionnaires. Data analyses were conducted using stepwise multiple regression, Pearson's correlation coefficients, 1-test, and ANOVA. Results : Health promoting lifestyle was significantly different by age, religion, occupation, and the length of residence. Those insured and those with no current medial diagnosis revealed significantly higher score in health promoting lifestyle than their counterparts. As for the level of anxiety, significant differences were found by educational level, marital status, occupation, income, and the length of residence. Self-esteem varied significantly by education, marital status, occupation, income, and the length of residence. Those with no current medical diagnosis and those insured experienced significantly higher level of self-esteem than their counterparts. Negative correlations were observed between health promoting lifestyle and anxiety. Perceived health status at present was positively correlated to perceived health status in the future. Health promoting lifestyle was significantly predicted by anxiety, age, and insurance. Conclusions : The above findings suggested that it is necessary to develop programs improving the perceived health status and lowering the level of anxiety. In this context, further researches on the relation between health promoting lifestyle and anxiety is required.

In order to extend the life time of building and civil infra-structure, nowadays, patch type fibrous composite materials are widely used. Retrofitted concrete columns and beams gain the stiffness and strength, but they lose toughness and show brittle failure. Usually, the cracks of concrete structures are visible with naked eyes and the status of the structure in the life cycle is estimated with visible inspection. After retrofitting of the structure, crack visibility is blocked by retrofitted composite materials. Therefore, structural monitoring after retrofitting is indispensible and self diagnosis method with optical fiber sensor is very useful. In this paper, We try to detect peel out effect and find the strain difference between main structure and retrofitting patch material when they separate each other.

The R.C Building will be superannuated as time passes. This program is generated by propagation of cracks. In order to manage such cracks, time and efforts, expense, etc. are required. In this study, glass sensors were embedding in a model beam and column and leakage of fluorescence and adhesive material was investigated. Further, currents in glass pipe were observed to find the leakage of liquid in glass pipes. Progressive cracks generated by cause the fracture of glass pipes. Therefore, the liquid become to flow and electric current stops, and the cracked part of the member can be found easily. Moreover, the adhesive delays progressive cracking system that responds in air, and the life of a structure can be made to extend. The purpose of this research is to develop of low price sensors that can perform of self-diagnosis in addition to ability of concrete repair concrete to damage.

Substation facilities have become large and complex in the electric power systems. Development of condition monitoring and diagnosis techniques have been very important to improve the security of substation transformers. This paper presents a method to analyze the cause and the degree of aging of power transformers by Self organizing map(SOM). Dissolved gas data were non-linearly transformed by sigmoid function to make determination of SOM close to that of human. Potential of a failure and the degree of aging of a normal transformer are identified by using the proposed quantitative criterion. Furthermore, transformer aging is monitored by the proposed criterion for a set of transformers. To demonstrate the validity of the proposed method, a case study is performed and its results are presented.

Bluetooth is the most promising network paradigm which ca open the new area in the information technology. Especially, bluetooth can link all the electrical products and PCs(Personal Computer) to cellular phone or PDA. In this paper, the data from ECU which are gathered by scanner are communicated between tow PCs using the bluethooth modules. The acquired data are ECU's self diagnosis signal and sensor output signal. Self diagnosis signals are very important to check the ECU's state and sensor output signals. Using these data, the possibility of wireless communication with ECU is developed and verified. Protocol stack of bluetooth is L2CAP through HCI and wireless communication software of ECU's signal is developed using VC++ in Windows 98 environment.

Purpose: The purpose of this study was to explore the self management and related factors that affect the self management of diabetes between the middle aged and elderly groups. Method: This study was based by the conceptual framework of Cox's interaction model of client health behavior. The subjects were two groups; the middle aged group, 80 and the elderly group, 85 who were diabetes mellitus patients. Result: In the middle aged group, gender, education and social support were significantly correlated with self-management of diabetes mellitus. In the elderly group, gender, education, social support and the duration of diagnosis were significantly correlated with self-management of diabetes mellitus. In too middle aged group, the intrinsic motivation of diabetes mellitus patients and their understanding of diabetes were significantly correlated with self-management of diabetes mellitus. Understanding of diabetes and self perception were significantly correlated with self-management in middle aged group. In the elderly group, intrinsic motivation, understanding of diabetes and the attitude of the patients were significantly correlated with self-management Conclusion: In the middle aged group, maintaining a positive attitude of diabetes, reducing stress and continuous social support were important for improving self-management of diabetes mellitus. In the elderly group, enhancing their knowledge of diabetes, and maintaining continuous social support were important to improve self-management of diabetes mellitus.

This paper investigates an algorithm for robust fault diagnosis in robot manipulators. The TOSM (Third Order Sliding Mode observer) provides both theoretically exact observation and unknown fault identification without filtration. The EOI (Equivalent Output Injections) of the TOSM observers can be used as residuals for the problem of fault diagnosis and to identify the unknown faults. The obtained fault information can be used for fault detection, isolation as well as fault accommodation to the self-correcting failure system. The computer simulation results for a PUMA 560 robot are shown to verify the effectiveness of the proposed strategy.
