The purpose of this study was to evaluate the comfort of PET clothing treated by UV. The physiological responses of the human body were investigated. Mean skin temperature and physiological signals such as Electroencephalogram (EEG), and heart rate (Electrocardiogram, (ECG)) were examined for 20 minutes during stable wearing conditions. Mean skin temperature was measured every two seconds using Ramanathan's method. Physiological responses were measured using Biopac MP100 series and analyzed using the software, Acqknowledge 3.5.2. Psychological effects were analyzed every five minutes. Comfort of untreated PET clothing decreased with the passage of time. Compared with PET clothing untreated, treated for 30 minutes, and treated for 90 minutes, the analysis of EEG showed that PET clothing treated for 90 minutes was the most comfortable after 20 minutes. In addition, the interval of the heart rate shown on the ECG was the highest in PET clothing treated for 90 minutes. Skin temperature was the lowest in PET treated for 90 minutes. We thus conclude that suitable UV irradiation would improve comfort.

The Purposes of this study are to determine differences of body temperature between Right arid left subligual areas itself and differences depending upon the utilization rate of mastication according to time intervals and to determine the length of time necessary for temperature taking. This Experiment was conducted from Oct 6 through Oct 11, 1975. in which accurately tested clinical Centigrade Thermometers have been utilized. Two thermometers were inserted simultaneously under the right and left sublingual areas and the mouth kept closed while thermometers were in Place. Temperature readings were dr no at three minutes, five minutes and ten minutes. These procedures were repeated one hundred times to different subjects and the data were analyzed statistically by means of the t-test and the F-ratio. Under the 10 hypotheses designed for this study, The findings obtained are as follows; 1. The body temperatures taken at 3, 5, 10minutes intervals in the left sublingual areas were significantly higher than in the right sublingual areas , The average differences of body temperature between the right and left sublingual areas were 0.09$^{\circ}C$, 0.05$^{\circ}C$ and 0.03$^{\circ}C$ in the oder of time interval of 3, 5, and 10 minutes. 2. The body temperatures taken in the right sublingual areas among three different temperature readings, 3, 5 and 10 minutes were significantly different in 57 subjects who have been utilizing evenly both sides of the Teeth. The average readings in a group taking for 3 minutes was 37.04$^{\circ}C$, for 5 minutes 37.15$^{\circ}C$ and for 10minutes 37.28$^{\circ}C$. 3. The body temperatures taken in the left sublingual areas among three different temperature readings, 3, 5 and 10 minutes were significantly different in 57 subjects who have been utilizing evenly both sides of the tenth. The average reading in a group taking for 3 minutes was 37.13$^{\circ}C$, for 5 minutes 37.2$^{\circ}C$ and for 10 minutes 37.31$^{\circ}C$. 4., Oral temperatures taken at 3, 5, 10 minutes intervals at the side of mouth utilized for more frequent mastication were Significantly higher than the other side. The average differences of body temperature between more frequently utilized side and Less frequently utilized side were 0.08f, 0.08f and 0.09f in the order of time interval of 3, 5 and 10 minutes. 5. Oral temperature taken at the side of mouth more frequently utilized for mastication among three different temperature readings, 3, 5 and 10 minutes were significantly different in 43 subjects who have been unequally utilizing either side of teeth. The average reading in a group taking for 3 minutes was 37.09$^{\circ}C$, for 5 minutes 37.17$^{\circ}C$ and for 10 minutes 37.3$^{\circ}C$. 6. Oral temperature taken at the side of mouth less frequently utilized for mastication among three different temperature readings 3, 5 and 10 minutes were significantly different in 43 subjects who have been unequally utilizing either side of teeth. The average reading in a group taking for 3 minutes was 37.01$^{\circ}C$, for S minutes 37.09$^{\circ}C$ and for minutes 37.21$^{\circ}C$. As a result of this study, these differences among time intervals were statistically significant, but there were not so much differences as to be considered important in the clinical practice. Therefore, there would be clinically little difference between two groups who are taking for 3 minutes and for 10 minutes.

Background: Ischemic preconditioning enhances the tolerance of myocardium against ischemia/reperfusion injury, with the enhancement of the recovery of post-ischemic myocardial function. This study was disigned to assess whether the protective effect of ischemic preconditioning could provide one additional hour of myocardial preservation in four hour myocardial ischemia in a rate heart. Material and method: Fourty four Spargue-Dawley rats, weighing 300~450gm, were divided into four groups. Group 1(n=7) and group 3(n=12) were subjected to 30 minutes of aerobic Langendorff perfusion without ischemic preconditioning and then preserved in saline solution at 2~4$^{\circ}C$ for 4 hours and 5 respectively. Group 2(n=7) and group 4(n=18) were perfused in the same way for 20 minutes, followed by 3 minutes of global mormothermic ischemia and 10 minutes of perfusion and then preserved in the same cold saline solution for 4 hours and 5 hours respectively. Heart rate, left ventricular developed pressure(LVDP), and coronary flow were measured at 15 minutes during perfusion as baseline. Spontaneous defibrillation time was measured after reperfusion. Heart rate, LVDP, and coronary flow were also recorded at 15 minutes, 30 minutes, and 45 minutes during reperfusion. Samples of the apical left ventricular wall were studied using a transmission electron microscope. Result: Time of spontaneous defibrillation(TSD) was significantly longer in group 4 than in group 1(p<0.001), and TSD in group 1 was significantly longer in comparision to that of group 2(p<0.05). Heart rate at 45 minutes was significantly higher in group 1 than in group 4(p<0.05). Heart rate at 15 min was significantly higher in group 2 than in group 1(p<0.001) and in group 4 than in group 3(p<0.05). Left ventricular developed pressure(LVDP) at 30 minutes and 45 minutes was higher in group 1 than in group 4(p<0.01), LVDP at 45 minutes was higher in group 4 than in group 3(p<0.05). Rate-pressure product(RPP) at 30 minutes and 45 minutes was higher in group 1 than in group 4(p<0.05). RPP at 15 minutes was higher in group 2 than in group 1(p<0.01). RPP at 30 minutes and 45 minutes was higher in group 4 than in group 3(p<0.05). Group 2 showed relatively less sarcoplasmic edema and less nuclear chromatin clearance than group 1. Group 4 showed less myocardial cell damage than group 3, group 4 showed less myocardial cell damage than group 3, group 4 showed more myocardial cell edema than group 1. Conclusion: Ischemic preconditioning enhanced the recovery of postischemic myocardial function after 4 hours and 5 hours preservation. However, it was not demonstrated that ischemic preconditioning could definitely provide one additional hour of myocardial preservation in four hour myocardial ischemia in a rat heart.

The traditional food - jungkwa of Korea, is difficult to manufacture. In this study, jungkwa with carrots was made in a rice cooker to simplify preparation. The boiling times for red color, chewiness and overall acceptability of jungkwa with carrots in a rice cooker as compared to the traditional method were 135 minutes, 150 minutes, 165 minutes, 180 minutes and 195 minutes, respectively. The rice cooker produced a lower moisture content in jungkwa with carrots when cooked for a longer time period, whereas the sugar content increased significantly. The color value of jungkwa with carrots was reduced at a longer boiling time as compared to the traditional method, yellowness increased when boiling time was longer than 195 minutes, whereas it remained the same with the traditional method. The hardness of jungkwa with carrots increased and candied jungkwa's result increased significantly when the boiling time was longer than 165 minutes. The rice cooker created a similar chewiness even when boiling time was over 165 minutes, although not consistently. The sensory evaluation scores of jungkwa made with carrots in terms of appearance, smell, taste, texture and overall preference were highest at 150 minutes and 165 minutes. Boiling jungkwa for 150 minutes in the rice cooker is the traditional method which simmers jungkwa at a lower timethan the preference time. Therefore, the best time for boiling jungkwa in the rice cooker highest was 165 minutes. After storage for 15 days chewiness and moisture content of jungkwa made with carrots at different boiling times, increased and decreases respectively. Therefore, the rice cooker can used to achieve comparable jungkwa without the traditional method.

This study was conducted to evaluate breakthrough characteristics of respirator cartridge using multi-organic vapors, including carbon tetrachloride, trichloroethylene, and toluene. The organic vapors were used as single phase, binary system, and ternary system. The results are summarized as follows. 1. Organic vapors studied were 1,000 ppm, 750 ppm, 500 ppm and 250 ppm in single phase. Carbon tetrachloride having the highest molecular weight showed the breakthrough first, and breakthrough sequency by organic vapor was dependent on its molecular weight. The 10% breakthrough times at 1,000 ppm of organic vapor were 97 minutes for carbon tetrachloride, 129 minutes for trichloroethylene and 135 minutes for toluene. 2. When concentrations of organic vapors were at levels of the Threshold Limit Values, the lives of the respirator cartridges were 122 hours in carbon tetrachloride, 18 hours in trichloroethylene and 28 hours in toluene. 3. In the binary system at a total concentration of 1,000 ppm with carbon tetrachloride and trichloroethylene, breakthrough times ranged from 104 minutes to 125 minutes, which were longer than 97 minutes in a single phase (1,000 ppm) for carbon tetrachloride, but shorter than breakthrough times for TCE and Toluene. 4. Breakthrough times in the binary system with carbon tetrachloride and toluene were 131~132 minutes. 5. Breakthrough times in the ternary system with carbon tetrachloride, toluene, and trichloroethyl ene were $120{\pm}8$ minutes, which were longer than 97 minutes in the single phase (1,000 ppm) for carbon tetrachloride, equal to 129 minutes for trichloroethylene, and shorter than 135 minutes for toluene. Those were almost similar to $124{\pm}9$ minutes of breakthrough times in the binary systems.
