This study is a descriptive research to identify lifestyle for health promotion, health condition, and degree of life satisfaction based on Korean elderly's physical constitution. The interviewee of this research was 53 outpatients of Oriental herbal medicine hospitals who are the residents either in Seoul or Taegu city. The data collection was performed during the March to the November of 1999. The research tools used for the measurement of the lifestyle for health promotion was "The Health Promoting Lifestyle Profile" developed by Walker, Sechrist and Pender. Measurement of the health condition was carried out using CMI(Cornell Medical Index) developed by Brodman, Erdmann, Lorge and Wolff. The Index for degree of the life satisfaction of elderly developed by Yun Jin was utilized to measure the degree of life satisfaction. Data analysis was performed using SPSSWin 9.0 software. In some cases, frequency, percentile, t-test, ANOVA or Pearson Correlation was also used to meet the specific research purposes when necessary. Tukey test was done for the post test. The conclusions are as follows. 1) The ANOVA test showed a significant difference in the lifestyle for the health promotion depending on physical constitutions of the interviewee. According to the Tukey test, 태음인 ($103.67{\pm}16.81$) performed better lifestyle for the health promotion than SOEMIN(少陰人, $85.34{\pm}12.69$) and 소양인($88.47{\pm}16.81$) (F=6.72, p=.003). 2) The result of the Pearson Correlation showed a positive correlation between the lifestyle for health promotion and health condition. As a result, the group practicing lifestyle for health promotion maintained a good health condition. Result of the Pearson Correlation also showed a proportional correlation between the lifestyle for health promotion and life satisfaction. Accordingly, the group practicing lifestyle for health promotion maintained a high degree of life satisfaction. Finally, the result of the Pearson Correlation showed a proportional correlation between the health condition and the degree of life satisfaction.

In this paper we discuss an algorithm for a real time transmission of moving color images on the TCP/IP network using wavelet transform and neural network. The image frames received from the camera are two-level wavelet-trans formed in the server, and are transmitted to the client on the network. Then, the client performs the inverse wavelet-transform using only the received pieces of each image frame within the prescribed time limit to display the moving images. When the TCP/IP network is busy, only a fraction of each image frame will be delivered. When the line is free, the whole frame of each image will be transferred to the client. The receiver warns the sender of the condition of traffic congestion in the network by sending a special short frame for this specific purpose. The sender can respond to this information of warning by simply reducing the data rate which is adjusted by a back-propagation neural network. In this way we can send a stream of moving images adaptively adjusting to the network traffic condition.

This study has analysed the ultimate loads acting on a wind turbine which is operating in a high turbulent flow condition because the ultimate loads are critical factors on the safe design of wind turbine. Since wind flow on the most parts of Korean mountainous are strongly influenced by complex configurations of the topography, turbulence intensity on somewhere is so stronger than an international design standard. For this reason, the characteristics of turbulent wind data collected from actual sites were analyzed and used for the ultimate load evaluation of the wind turbine. With the 270 design load cases on the international standards, the differences of ultimate loads on the wind turbine operating in the standard or high turbulent wind condition are calculated and compared for the an enhanced knowledge of the safe design basis. As are result, it is revealed the specific ultimate loads are strongly affected by the high turbulent wind conditions, thus the characteristics of turbulent flow must be considered during the design of wind turbine.

Normally, PV system is designed using local weather condition like lowest and highest temperature and irradiance. But this might give misleading results because it is not realistic data of PV module itself. To give more specific description of PV system, we tested photovoltaic(PV) modules' temperature, irradiance and maximum power generation characteristics from January to December in 2008 for 3kW PV system. From this, we could deeply analyze the accumulation temperature, electrical characteristics of PV module in various condition. So precise approach to PV system design can be done. The detail description is specified as the following paper.

In the tobacco industry, it is important to study the change of mechanical property occurring the expansion process. The purpose of this study is to attain basic data for development of a tobacco expansion method. 1 . Freon gas was adsorbed to tobacco under various conditions of temperature, relative humidity and pressure, and then the amount of freon gas adsorbed was analyzed by GC. Freon adsorption rate of Burley 21 was more than that of By104 at the same condition and about 17 $\pm$ 1% moisture content produced better adsorption rate. 2. Freon adsorbed sample were heated to about $150^{circ}C\;to\;230^{\circ}C$ in a drying oven and recycle duct form about 2 to 30 seconds, and then the change of mechanical property were measured. Heated leaf was damaged when the tissue was pressed by the force of above $0.5x10^8dyn/cm^2$. The optimum condition of no damage of the sample was below the temperature of 15$0^{\circ}C$ and heating time of 10 seconds. It was more economically advantages to treated sample in a recycle duct than to be in a drying oven. By this process, the specific volume of the heated sample was increased from 80 to 110 percent in comparison to that of untreated sample.

Gene-expression analysis is increasingly important in biological research, with real-time reverse PCR (RTPCR) becoming the method of choice for high-throughput and accurate expression profiling of selected genes. However, this technique requires important preliminary work for standardizing and optimizing the many parameters involved in the analysis. Plant stress studies are more and more based on gene expression. The analysis of gene expression requires sensitive and reproducible measurements for specific mRNA sequence. Several genes are regulated in response to abitoic stresses, such as salinity, and their gene products function in stress response and tolerance. The design of the primers and TaqMan probes for real-time PCR assays were carried out using the Primer $Express^{TM}$ software 3.0. The PCR efficiency was estimated through the linear regression of the dilution curve. To understand the expression pattern of various genes under salt stressed condition, we have developed a unique public resource of 9 stress-related genes in poplar. In this study, real-time RT-PCR was used to quantify the transcript level of 10 genes (9 stress-related genes and 1 house keeping gene) that could play a role in adaptation of Populus davidiana. Real-time RT-PCR analyses exhibited different expression ratios of related genes. The data obtained showed that determination of mRNA levels could constitute a new approach to study the stress response of P. davidiana after adaptation during growth in salinity condition.
