Exercise-mediated physical treatment has attracted much recent interest. In particular, swimming is a representative exercise treatment method recommended for patients experiencing muscular and cardiovascular diseases. The present study sought to design a swimming-based exercise treatment management system. A survey questionnaire was completed by participants to assess the prevalence of muscular and cardiovascular diseases among adult males and females participating in swimming programs at sport centers in metropolitan regions of country. Using the Fuzzy Analytic Hierarchy Process (AHP) technique, weighted values of indices were determined, to maximize participant clarity. A patient management system model was devised using information technology. The favorable results are evidence of the validity of this approach. Additionally, the swimming-based exercise management system can be supplemented together with analyses of weighted values considering connectivity between established indices.

Recently, climate change had caused the frequency of rainfall occurrence and magnitude to increase. For this reason, disaster damage, recovery cost and casualties had also increased continuously. The establishment and operation of a storm and flood damage prediction system would serve as a tool for the government in order to draft a disaster prevention policy. In Korea, the casualties or damage function and damage estimation technique is currently on it early development stage since it still lacks direct and indirect damage scale calculation, limitations in the development of prediction techniques, etc. accordingly, It is need for the development of Storm and flood damage prediction system to support disaster response phase by decision making. In this study, foreign systems were analyzed and then strategies on how to apply such systems into Korea's situation developed. It suggested the need for considering various damage functions with real-time/scenario-based damage prediction and inventory setting from foreign research cases. As a result, the storm and flood damage prediction system framework was designed to meet domestic situation wherein its development will include the development of real time/scenario-based storm and flood damage prediction. Through the development of this system, an effective disaster response for business support system can be developed.

Dynamic characteristics of a tilting pad bearing strongly depend on the direction of applying load as well as the magnitude. As the bearing load of geared compressor are determined by aerodynamic forces of impellers and mesh forces of helical gears in accordance with operating speed, dynamic coefficient of each bearing also varies with respect to rotor speed. Hence, in order to ensure rotordynamic stability of geared compressor, accurate estimations of bearing loads and corresponding dynamic characteristics of tilting pad bearings in accordance with operating speeds are highly requested. In this study, bearing dynamic test rig was developed based on floating bearing housing design, with speed range from 3000 to 32,000 rpm. In order to precisely estimate lateral critical speeds and the stability of pinion rotor of integrally geared compressor, the experimental investigation has been carried out on five pads tilting-pad journal bearings of 45 mm in diameter. Static eccentricities of the tilting pad bearings were investigated with various load directions and corresponding dynamic characteristics were also obtained. Multifrequency excitations have been used to evaluate the nature of frequency dependency of the bearing dynamic coefficients. Using experimentally identified dynamic coefficients of rocker-back type tilting pad bearing with respect to rotating speed, rotordynamic analysis of gear-driven pinion rotor was carried out and compared with shaft vibration measurement. The predicted rotor behavior showed good agreement with measured one.
