Paraquat poisoning can cause severe multiple organ failureinvolving the kidneys, liver, lungs, adrenals, and central nervoussystem. The toxic effect of paraquat on the lung manifestsas pulmonary edema, hypoxia, respiratory failure, andpulmonary fibrosis. However, optimal guidelines for treatmentof lung fibrosis following paraquat ingestion are not available. We experienced two cases, a 45-year-old Korean male and a66-year-old Korean male, who visited the emergency centerbecause of paraquat poisoning. They initially received methylprednisolonepulse therapy and cyclophosphamide. Thenthey experienced pulmonary fibrosis approximately 10 daysafter admission during renal recovery. Although steroid pulsetherapy with cyclophosphamide was reported to reduce mortalitydue to paraquat poisoning, the side effects of cyclophosphamidetreatment were concerning in our patients, who hadalready received cyclophosphamide. Therefore, we decidedto repeat steroid pulse therapy without cyclophosphamide. Fortunately, pulmonary fibrosis in these two patients resolvedafter repeated steroid pulse therapy. Thus, steroid pulse therapyalone could benefit patients with lung fibrosis, who havealready received steroid and cyclophosphamide treatment. Herein, we report on two cases of pulmonary fibrosis due toparaquat poisoning that were treated successfully with repeatedsteroid pulse therapy.

The purpose of this study is estimate maximum muscle strength by measuring only maximum mumber of contractions at a given load(kg) with no direct determination of maximum muscle strength in isometric. Therfore, was designed to investigate the laws of various weight-loads (P) and number of contraction(N). Subjects were 75 baseball players whose ages ranged between 18 and 23 years old. Each subject measured the maximum mumber of contractions during extension and contraction movements between 45 degrees and 110 degrees of right elbow joint angle by using arm ergometer. The rate of tempo was once every two seconds. And, In this study, the value of maximal isometric stength was applied elbow joint engle in 45 degrees. The results may be summarized as follows : 1) It was significantly that maximum number of contractions during training group was higher than that of De-training group (P<0.05). 2) In the total, it was significantly that maximum mumber of contractions during Low group of maximum muscle strength was higher than that of High group by measuring 70 to 90% Loads (P<0.01) 3) In the total, it was significantly that maximum number of contractions during High grip strength was higher than that of Low group by measuring 50% Loads(P<0.05). 4) Relationship between Load(kg) and number of contractions has shown to be well fitted to an exponential equation : N = -allP + b. On the basis of these findings, it was suggested that estimation of maximum muscle strength relationship between load and mumber of contractions brachial biceps more adequate weight-loads than relative load(%).

A simple method for generating pores in a cellulose acetate (CA) polymer matrix was developed using a combination of an ionic liquid and water pressure treatment. A porous CA membrane was successfully prepared using the ionic liquid (BMIM-BF4) and subsequent water pressure treatment. Pores were generated in the CA polymer matrix when the CA/ionic liquid composite was subjected to water pressure. The characteristics of the thus-generated porous membrane were evaluated using porosimetry. FT-IR and Thermogravimetric analysis (TGA) showed that when the CA polymer was subjected to water pressure, most of the BMIM-BF4 incorporated in the polymer during its preparation was removed, thereby generating the observed pores. In addition, it was observed that the flux varied with water pressure, indicating that the pore size was controllable.

This study investigated the relationship between self-esteem, perceived competence and participation of masters swimming. Participants(N=322) were randomly selected from masters swimming program of swimming pool in seoul and Kyung-Kee. Results indicated that the meaning significant found the representation of duration of contingencies and participation of swimming competition in masters swimming. In sum, firstly, in the participation of masters swimming, every time participation in swimming competition assigned greater than the other participant to perceived competence, and in duration of contingencies of participation, 4-7 years participation group assigned greater than the order participant group to perceived competence. Secondly, in the participation of masters swimming, every time participation in swimming competition assigned greater than the other participant to self-esteem, and in duration of contingencies of participation, 2-4 years participation group assigned greater than the participant group to self-esteem. Thirdly, in the participation of masters swimming, perceived competence is postitively influence on self-esteem.

The purpose of this study is to research into the anxiety level of competition state that Korean female athletes generally feel before a competiton. The inspection method in this study was CSAI-2 developed by Martens and his colleagues in 1983. As a measurement tool of the anxiety level of competition state felt by athletes before a competition, this inspection gauge consists of three subordinate measure-cognitive state of anxiety, physical state of anxiety, state confidence. The independent variables were ability[skill]level(superiority/inferiority), kind of events(short-distance/mid and long-distance race), career(less than 3 years/4-6 years/over 7 years), and on the other hand, the dependent variable was the anxiety factors of competition state in sports, which was carried out by t-test and One-Way ANOVA. The statistic level of hypothesis was established under p<.05. The major results obtained by the analysis of collected data are as follows: With regard to the anxiety level of state in female athletes' careers, it turned out to be a significant distinction in that an athlete with a career of 4-6 years and over 7 years(p<.05).
