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)

This study pursues the problems of plan photogrammetry which is widely used in somatotyping at present, and find out a method which can improve accuracy of measurement on the basis of principles and mechanisms of photography the basic foundation of the photographic analysis methods. As a result, this study proposes a new method which is based on the reference point method and perspective coordinate system. And the test measurement was operated to compare the measurement accuracy of the proposed method and the method based on reference grid screen method and perpendicular coordinate system which is commonly used at present. The result of this test measurement showed that the proposed method has higher accuracy. Two reasons can be pointed out for the improvement of measuring accuracy. The first reason is that the proposed perspective coordinate system reduces the perspective distortion of photography. And second reason is that measuring points can be closely place to the scale and coordinate reference plan of measurement by the proposed reference point method which make possible to place measuring object(or person) at the center of scale and coordinate reference plan by utilizing reference points of measurement in the three dimensional space not on screen.

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.

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 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℃.

전통중편의 단백영양 보강을 위하여 동충하초를 첨가하여 중편의 이화학적, 기계적, 관능적 품질특성을 조사하였다. 동충하초 첨가량을 달리한 중편의 부피는 동충하초 첨가군이 대조군에 비해 증가하였고 pH는 동충하초 5%첨가 중편이 가장 낮게 나타났다. 수분은 대조군에 비해 첨가군의 수분 함량이 낮았고(p<0.01) 동충하초 첨가군 사이에 유의적인 차이는 없었다. 아미노산 함량은 대조군보다 동충하초 첨가군이 높았으며 필수아미노산을 골고루 함유하고 특히 Leucine, Phenylalanine, Arginine이 높았다. 동충하초첨가 중편의 texture변화에서 색도 중 L값은 대조군에 비해 동충하초 첨가량이 증가할수록 감소하였으며 반면에 a, b값은 첨가량이 증가할수록 증가하였다. texture 측정에서는 껌성은 5% 첨가군이 낮게 나타났고, brittlenes는 7% 첨가군이 대조군과 다른 첨가군중에서 가장 높게 나타났다. 관능검사에서 texture에서는 응집성이 5% 첨가군, 탄력성은 3% 첨가군이 가장 높게 평가되었으나 유의적인 차이는 없었다. flavor에서 stale grain flavor과 bitterness는 동충하초 첨가량을 증가시킬수록 높게 나타나는 경향을 보였다. 이상의 결과에서 동충하초 중편의 제조에서 이화학적 특성, 기계적 특성, 관능적 특성을 종합했을 때 동충하초 농도를 3%, 5% 첨가시 최적농도임을 도출해 내고 품질이 향상됨을 확인할 수 있었다. higher The Hunter color test showed lower L values with higher amounts of added JP to the Jeung-Pyun. In the sensory test, the 7% added group had the strongest color according to the texture; the highest cohesiveness was shown in the 5% added group. and the highest springiness was shown by the 3% added group, but none of these showed any significant differences. As for flavor, the more JP added the higher the stale grain flavor and bitterness. In the result of the overall acceptability test, the stale grain flavor of the 5% added group showed the highest values for the favorite texture and flavor. From the results of this experiment, when making stale grain flavored Jeung-Pyun, the 3 and 5% added groups were the optimum concentrations for the observed improvements in the quality. This study was carried out to investigate the possibility of improving the quality characteristics of Jeung-Pyun, by the addition of Paecilomyces japonica powder (JP). Regarding the volume of the Jeung-Pyun fermentation, with respect to the different amounts of JP added, the groups containing JP showed increased volumes, and as for the pH, the group containing 5% showed the lowest value. Regarding the moisture content, the groups containing JP showed lower moisture contents than the control group. Regarding the amino acid content, the control group showed a higher amino acid content than those of the JP containing groups, and contained an even amount of essential amino acids, and Leucine, Phenylalanine and Arginine were especially
