N/A Background: Magnetocardiogram (MCG), which records the changes of magnetic fields generated by the heart`s electrical activity, theoritically can provide unique data for clinical application. To date, MCG has been investigated only at a single time point after myocardial infarction (MI) with severe left ventricular dysfunction in rats. The purpose of the present study was to investigate sequential changes of MCG after MI and to evaluate effects of infarct size on MCG. Methods: Acute MI were induced by the permanent ligation of left coronary artery in 22 rats. Magnetic fields were recorded just above a rat with Nb Superconducting Quantum Interference Device (SQUID) gradiometer inside a magnetically shielded room. MCG was measured before and immediately after surgery and it was subsequently recorded at the time points of 1, 4 and 6 hours post operatively. MCG was also measured at 1, 3, 7 and 21 days after surgery. Results: Elevation of ST segment and appearance of pathological Q wave on the MCG were evident immediately after the ligation of coronary artery and persisted to 6 hours after MI. On MCG, ST segment was depressed and T wave was inverted from 1 day after MI. In rats with small-and moderate- sized MI (infarct size〈30%), ST depression returned to near the isoelectric level and Q wave disappeared from 7 days after MI. However, ST depression and Q wave were still present in rats with larger infarct (infarct size≥30%). Conclusion: Evolutional changes of MCG were well-recognized up to 21 days after MI. Furthermore, the infarct size can be expressed by the extent of Q wave and ST segment depression on MCG. Taken together, these data indicate that MCG is a helpful modality for the diagnosis, evaluation of infarct size and follow up after MI.(Korean J Med 62:42-48, 2002)

Zoysia japonica Steud. is a warm-season lawn grass popular in Korea and elsewhere. They are cultivated in many places such as river banks, roadside, and play grounds. However, there still is a disadvantage of frequent mowing, and the grass grows poorly under the chilly conditions. To develop a grass variety that circumvents these drawbacks, we cloned the chitininducible gibberellins-responsive1 gene (CIGR1) from zoysiagrass. The full length of the ZjCIGR1 (Zj; Zoysia japonica Steud.) gene was obtained by 5′/3′ RACE PCR and the phylogenetic tree showed that it belonged to the CIGR1-subgroup in the PAT1-group of GRAS protein family. Expression of the ZjCIGR1 in wild-type plants was confirmed in roots, meristems, leaves, and flowers, especially high in the flowers. The transgenic zoysiagrass was confirmed by PCR using gene-specific primers, phosphinothricin-acetyl-transferase (PAT) strip test, and Southern blot analysis. ZjCIGR1-overexpressing plants acquired tolerance to cold stress displaying morphological phenotypes characteristic of stress resistance. In addition, in the transformants, expression of the ZjCIGR1 as well as cold-regulated (COR) gene was increased compared to the wild-type plants under cold stress condition. These results suggest that ZjCIGR1 gene is an important candidate for regulating cold stress resistance.

Numerical methods that are known as Monte as Monte Carlo methods can be loosely described as statistical simulation methods, where statistical simulation is defined in quite general terms to be any method that utilizes sequences of random numbers to perform the simulation. Monte Carlo methods are now used routinely in many problems, the simulation of the esoteric subnuclear processes in high energy physics experiments, cellular automata, self-organized critical phenomena, the Ising spin glass, the simulation of a Bingo game, etc. The physical processes are simulated directly, and there are no needs to even write down the differential equations that describe the behaviors of the systems. The only requirement is that the physical systems be described by probability density functions. We consider with the Monte Carlo variational method and the Monte Carlo path integral method(MCPI). These methods are used to calculate the energy of the ground states of H2 molecule by the formal similarity between the Schroedinger equation and the multi-dimensional diffusion equation.

Objectives: The purposes of this study were to investigate nursing students' knowledge and attitudes toward the elderly, to examine the correlation between knowledge and attitudes, and to identify predictors of nursing students' attitudes toward the elderly. Method: Study participants were 195 nursing students who enrolled in a university located in Gwangju. Data were collected using structured questionnaires. Results: The average FAQ Ⅰ score for nursing students in this study was 50.2%. The level of nursing students' knowledge was relatively low compared to knowledge of Western nursing students in previous studies. Moreover, the average scores of psychological dimension and family/sociological dimension were lower than those of physical/physiological dimension. Negative biases were prevalent when the biased scores were computed. Nursing students also reported a little preference for working with older patients after graduation. Although the average attitude score was in a neutral range, the number of items in a negative attitude score range were more than those in a positive attitude score range. Contrary to expectation, the correlation between knowledge and attitude was not statistically significant. Nursing students who have clinical experiences with the elderly reported higher scores on FAQ Ⅰ than their counterparts. A current relationship with elderly living in their household was a significant predictor of nursing students' attitudes toward the elderly. Conclusion: Results from this study suggest that nursing education should be directed to increase the nursing students' knowledge and positive attitudes toward the elderly. Exposure to well elderly as clients before they are hospitalized or institutionalized may be helpful to increase nursing students' positive attitudes toward the elderly.

The purpose of this paper is to select 7 male athletes and female athletes of high school, and to compare their active potential differences of upper arm muscles according to characteristic of a racket. the results obtained are as follows: 1. According to the accumulative distribution rate of racket material, graphite and wood material show better efficiency in case of brachio radialis muscle of male athletes, but the racket material shows no constant efficiency in brachii radialis muscle of female athletes. In case of flexor carpi radialis muscle, wood material provides better efficiency only for male athletes. In case of triceps brachii muscle, wood material gives better efficiency to males athletes and steel material gives better efficiency to females athletes. Especially in case of biceps brachii muscle, neither male nor female athletes are influenced by racket materials at impact. 2. In the muscle load rate according to racket material, wood has the highest muscle active potential and graphite has the lowest active potential. Therefore, graphite is thoght to be better in the efficiency of muscle load rate.

Sports technology encompasses a wide range of disciplines from biomechanics to engineering. As a consequence, researchers working in sports technology find that their work falls neither in the field of traditional sports nor in mainstram engineering. Also Sports Engineering is an international journal publishing original papers on the application of engineering and science to sport. The journal intends to fill the niche area which lies between classical engineering and sports science and aims to bride the gap between the analysis of the equipment and of the athlete. Area of interest include the mechanics and dynamics of sport, the analysis of movement, instrument equipment design, surface interaction, materials and modeling. These topics may be applied to technology in almost any sports. The Sports Engineering will be of particular interest to Engineering, Physics, Mathematics and Sports Science Departments and The International Sport Engineering Association(ISEA) will act forum where research, industry and the sports sector can exchange knowledge and innovative ideas.
