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)

Hepatocellular carcinoma frequently metastasizes through direct extension, lymphatic, and hematogenous routes. The most common sites of metastasis are the lungs and the lymph nodes, glands, bones, spleen, kidneys, colon, and pleura are the sites of metastasis in decreasing order of frequency. But metastasis to the ovary is very rare. It is thought that metastasize to the ovary occurs through infiltration or dissemination. However, we observed ovarian metastasis of primary hepatic tumor in a 34-year old female who suffered from lower abdominal pain. At first, it was diagnosed as a primary ovarian tumor. But histologically, it presented sinusoidal pattern surrounded by the tumor cells and contained rounded by the tumor cells and contained round hyaline globules in minority of the cytoplasm. Then, the histologic features of percutaneous, sono-guided liver biopsy speecimen of the liver mass are similar to those of resected ovarian tissues. Therefore, we concluded that ovarian tumor was originated from hepatocellular carcinoma. In summary, this report examines a case of hepatocellular carcinoma with ovarian metastasis in a female and reviews the literature.

The purpose of this study was to investigate the effect of muscular resistance training on abdominal fat. Subjects were composed of sixteen obese middle-aged women. Resistance training was performed 60minutes per day, 5days per week at 60% of 1RM during 1~12weeks and at 70% of 1RM during 13~24weeks. The items for abdominal fat volume were measured subcutaneous fat volume(SFV), visceral fat volume(VFV), VFV/SFV by computed tomography. Paired t-test was used to evaluate the difference of baseline and after 24 weeks muscular resistance training. The 0.05 level of significance was as critical level for the study. The results of this study are as follow; 1. Body weight and %fat were significantly(p<.05) decreased in muscular resistance training group. 2. VFV and SFV were significantly decreased in muscular resistance training group. 3. VFV/SFV was significantly decreased in muscular resistance training group. In conclusion, visceral fat and subcutaneous fat were decreased in muscular resistance training. So it is maybe thought that long-term muscular resistance training improved body composition for obesity treatment.

The purpose of this study was to find out if the mental practice for a certain period will influenced the record improvement of ball-throwing or not. We randomly picked out forty boy student subjects who were in the third grade in middle school. We divided the subjects into five groups-the first group (only mental practice), the second (physical practice after mental practice). the third (mental practice after physical one), the fourth(only mental practice), and the fifth (non practice)-and had each group try the practice three time, every week for eight weeks. through the close comparison and analysis over the records measured before and after the practice, we came to a conclusion like this : 1. Only mental Practice isn't effective. 2. Physical practice, physical after mental practice, mental practice after physical one, and all influence the record improvement of ball-throwing. 3. There is no any meaningful difference among physical practice, mental practice after physical one, and physical practice after mental one with each other. 4. Mental practice has no effect on the record improvement of ball-throwing.

This study aimes to inverstigate the changes of sgape of the Lower limb surface, the rate of the measurement of expansion and contraction caused by hip joint and knee joint movements. The replicas of the lower trunk and the lower limb surface were taken by using a gypsum method on 4 pre-shcool chdrens subjects under 5 standardized lower limb positions. Those replicas obtained were developed to the patterns and the changes in shope and area of those were measured. The characteristics of regional body surface changes were summarized as follows ; 1.The surface changes in the lower trunk and the lower limb seemed to be influenced directly by the direction and the amount of lower limb movement. 2.As a result of investigating into the rate of the expansion and contraction of the body surface area by the lower limb movements, the back area of the hip showed the maximum rate of expansion. 3.The rate of changes in the horizontal direction were little. The hip girth and knee girth showed the large rate extentions in flexion 90 at both the hip and knee joint. Therefor, when the lower clothing contrution for pre-school children at least the amount of ease of 1.0cm of hip girth and 3.5cm of knee girth must be made. 4.The changes in the vertical direction were apparently more than those in the horizontal one. This meant that the changesof the body surface area previously reported were largely effected from the changes in vertical direction. The center back line showed the maximum rate of extension. So when the lower clothing construction for pre-school children at least the amount of ease of 4.7cm dncenter back line must be made.

The purpose of this thesis was to investigate plato's view of body and soul from the core of his philosophy Idea, and its influences of his physical thoughts. Some important points of plato's physical thoughts were as follows. 1. In contrast to the general concept that Plato was the mere philosopher of metaphysical dualism an regarded the body as inferior to the soul, he compared the baby to thing and the soul to Idea, and suggested an inseparable relations between body and soul. 2. Plato emphasized physical education to achieve his " Ideal state" in which the great citizens and rulers could be brought up. 3. Plato insisted that physical education should go along mental education of the perfect character building and for the first time promoted firmly the position of that to one of two maintenance in the history of the world physical education. 4. On the basis of ideological thought of physical thoughts, Plato regarded physical education as essential in order to bring up the whole man who was harmonized and balanced with in his mind and body. 5. Plato explained physical education in detail from nursing period, infant period, juvenile period to the youth period. 6. Plato regarded the proper ingestim of nutrition along with the exercise as the principle of physical education. 7. Plato demanded to build three Gymnasiums respectively in the city and in the suburbs. cavalry school and even the teacher's houses. And he insisted that the facilities should be always opened for the enough use. In case it could not be fulfilled, he suggested lawful settlements. 8. In the general rules of personnel administration, Plato discoursed on the duty, qualification and organization.

The purpose of this study was to investigate the effect of Paecilomyces japonica mycelia(PJM) on pH, titrable acidity and microbiological quality of Jeungpyun(fermented rice cake). Jeungpyun prepared with 0?7% of PJM stored at 5℃ and 20℃ for 4 weeks and 7 days respectively. Before fermentation of Jeungpyun dough, viable cells of total bacterial counts(TBC), yeasts and lactic acid bacteria(LAB) were 6.0~9.8×10^6, 5.3~9.0×10^(6), 5.4~8.5×10^(6) CFU/g, respectively. During the fermentation of dough, viable cells of TBC, yeasts and LAB increased 0.3~0.4 log cycle and pH was decreased whereas acidity incresed as the progress of fermentation. Total viable cells in Jeungpyun before storage were 5.0×10¹ CFU/g. During storage of Jeungpyun, TBC, yeasts and LAB of control group increased 2.6, 2.4, 2.1 log cycle at 5℃ and 4.8, 4.6, 4.5 log cycle at 20℃, respectively, when reached at maximum level. Major microflora of Jeungpyun was composed of yeasts and LAB during fermentation of dough and storage at 5℃ and 20℃. Addition of PJM, inhibited the growth of microorganisms, the changes of pH and titrable acidity of Jeungpyun during storage at both of 5℃ and 20℃. From these results, the addition of PJM extended the shelf-life of Jeungpyun during storage at 5℃ and 20℃.
