Purpose: The purpose of this study was to explore the experiences of young adults with hypertension, using phenomenology in order to describe the essence of such experiences and to understand them from the patients' point of view. Methods: Participants in this study were 4 hypertension patients with ages ranging from 20 to 35 years old, living in Seoul city. Data were collected from in-depth interviews done from October to November in 2005. Colazzi method(1978) was used to analyze the data. Results: The 12 themes were extracted in this study ; 'Discovery by accident', 'Denial of the diagnosis', 'A disease unworthy of the young men', 'Guilty feeling toward their parents', 'Fear of death', 'Unconvinced reason', 'Worry about the future', 'Attribute all symptoms to the disease', 'Will of not life-long medication', 'Concern for fertility problem', 'Not convinced with current treatment method', 'Becoming unimportant'. Conclusion: The results of this study show that the young adult with hypertension will be in a high risk group of non compliance, so helpful program for them should be developed and the nurses need to pay more attention to the psychosocial aspect of nursing.

The pollution-free secondary Li ion battery has been developed recently. However due to short history of Li ion battery, the standards for characterized assessments and standardized testing methods have not been prepared and established yet. Also, the researches have not been done systematically regarding the operating methods of these new type of batteries. Such limited knowledge of new batteries emphasizes the importance of development of characterized assessment and the operating methods.

The advantages for using fuel cell instead of storages for powering electric vehicles are as follows : the energy density of fuel cell is greater than that of battery, fuel cell can be recharged much faster than battery. The objectives of this study are to investigate the status of Fuel Cell Vehicle technologies.

MCFC has been investigated for the last half centry as an alternative energy source. The operating temperature of MCFC is 650$^{\circ}C$, so it is more efficient than ocher fuel cells, and it has needed no nob metal element for the electrodes. we investigated electrochemical characteristics of separator for MCFC.

Lead-acid battery is used widely as a power source at a automobile, industrial machines. folk lifts. U.P.S. etc. Since lead-acid battery is cheaper than any other ones. But this battery has many disadvantages such as heavy, low energy density, environment problem etc. In this article, We introduce potential step methods to investigate corrosion behaviour of positive grids for lead alloyes.

The MCFC has conspicuous features and high potential in being used as an energy converter of various fuels to electricity and heat. However, the MCFC which use strongly corrosive molten carbonate at 650[$^{\circ}C$] have many problem. Systematic investigation on corrosion behavior of Fe/20Cr/Ti alloys has been done in (62+38)㏖ % (Li+K)CO$_3$ melt at 923K by using steady state polarization and electrochemical impedance spectroscopy method.
