  • Rats were studied during 45 minutes treadmill exercise to determine the effects of hyperglycemia and hyperlipidemia on the utilization of cardiac muscle glycogen, and the utilization of diaphragm muscle glycogen was also studied for comparing to cardiac muscle. The hyperglycemia was produced by ingestion of 25% glucose solution(lml/100gm, BW) and the hyperlipidemia by 10% intralipose ingestion(lml/l00gm, BW) with intraperitoneal injection of heparin(500 IU) 15 minutes before treadmill exercise. The mean blood glucose concentrations(mg/dL) in control and hyperglycemic rats were 110 and 145, respectively, and the mean plasma free fatty acid concentrations(${\mu}Eq/L$) in control, control exercise(control-E) and hyperlipidemia exercise(HL-E) rats were 247, 260 and 444, respectively. In the hyperglycemic trial, the cardiac muscle glycogen concentration was not significantly decreased by the exercise but the concentration in control rats was decreased to 73.9%(p<0.05). The glycogen concentration of diaphragm was significantly decreased in both groups by the exercise, but the hyperglycemia decreased the glycogen utilization by approximately 10% compared to the control. The cardiac muscle glycogen concentration was not decreased by the exercise in control and hyperlipidemic rats but the utilization of glycogen in hyperlipidemic rats is lower than that of the control. These data illustrate the sparing effect of hyperglycemia on cardiac muscle glycogen usage during exercise, but the effect of hyperlipidemia was not conclusive. In the skeletal muscle, the usage of glycogen by exercise was spared by both hyperglycemia and hyperlipidemia.

  • The effects of hyperglycemia and hyperlipidemia on utilization of muscle glycogen during 45 minute Session of treadmill running(26 m/min, 8% grade) were evaluated using Sprague Dawley rats, and the characteristics of the 4 different type of muscles, I.e., soleus, white and red gastrocnemius, and plantaris, on glycogen utilization were simultaneously investigated. Hyperglycemia was induced by 145-165 mg/dL of oral glucose administration, and hyperlipidemia was induced by combined treatment of intraperitoneal heparine injection of 444 uEq/L and 10 % intralipose oral adminstration. During the hyperglycemic trial, the glycogen utilization of plantaris muscle was decreased by 13 % in 45 minute session of treadmill running compared to the control trial(p<0.05), and the glycogen utilization of white gastrocnemius was also decreased. The sparing tendency of glycogen was observed in soleus and red gastrocnemius by 5-13 % during 30 and 45 minute session of treadmill running in hyperglycemic trial. There was no glycogen sparing effect of hyperlipidemia in soleus, red gastrocnemius and plantaris muscle subjected in this experiment during exercise. However, only a slight sparing tendency of white gastrocnemius muscle was observed. In summary, the glycogen sparing effect of hyperglycemia during exercise was observed in plantaris and white gastrocnemius muscles in rats. However, there was no glycogen sparing effect of hyperlipidemia in the 4 hindlimb muscles. It was observed that the glycogen sparing effect of hyperglycemia is more prominent in fast glycolytic muscle fibers.

  • The purpose of this paper is to analyze the political discussion and the success conditions on the digital democracy and issues for introducing e-party of Korean parties, and to propose alternatives for solving these issues. To accomplish this purpose, this paper review actual conditions of the digital politics, analyze on results of e-party driving of Korean parties, review issues for introducing e-party of Korean parties, and propose alternatives for solving these issues. Proposed conditions on digital politics and e-party development will contribute to the prosperity of the Korean politics. In near future, an empirical study on the standpoints of voters politicians will be followed.

  • In order to clarify the growth characteristic and Brix degree at different internodes, four varieties that are M81E 71-1, a Rio, a Sart and a Tamurama were seeded on, Apr. 5, Apr. 15, Apr. 25, May 5 and May 15, respectively. Delayed seeding increased plant hight and the growth pattern of the stem diameter and weight was tapesed off and lighted to upper location. Brix degree of internode was rapidly increased from just after heading date, and was slowly increased by rising upper side till before heading date. Brix degree of middle location(6th internode) was the highest of the stem in after heading date and interior side was the lowest. Brix percentage of 40∼45 days after heading had more than 15% in case of being seeded from Apr. 5 to May 5. Sweet sorghum that was seeded on May 15 was more than 17% in the Brix percentage of 35 days after heading and so the suitable seeding date in sourthern district was suggested on May 5. The plethora of soil moisture by rainfall was made decently lower Brix degree in 130∼140 days after seeding. Among the length and the diameter of internode, and Brix degree had negative correlation, between diameter and weight of internode were significantly positive correlation. But correlation coefficient had been a little bit different by varieties.
