We reported that acupuncture on $LI_4$ effected thermal change on $LI_4$ and ST25 area, And this study was performed on 100 healthy students to observe the effects of acupuncture at Hap-kok ($LI_4$) according to the meridian and qi-xue(氣血) phenomenon of oriental medicine's theory, The results was 1. In healthy man, mean skin temperatures of $LI_4$, ST25, CV12 areas(Control) were decreased, 2. In left $LI_4$ acupuncture group, the temperature of abdominal skin and $LI_4$ area had the tendency of increase, both right and left $LI_4$ acupuncture group, the temperature of abdominal skin and $LI_4$ area had not significant tendency. 3. In the research of thermal difference which eliminate a special region temperature, in the control group, the thermal changes had not significant tendency, in the left $LI_4$ acupuncture group and both right and left $LI_4$ acupuncture group, the thermal changes had tendency to be increased, 4. In the deviation analysis which mean of each group is excluded, in the control group, it turned out that deviation is regular for 10 minutes; in the left $LI_4$ acupuncture group and both right and left $LI_4$ acupuncture group, it turned out that deviation is more larger than the control group for 10 minutes. The above results indicates that Digital Thermography is a useful method to observe effects and changes by acupuncture stimulation on objective evaluation of phenomenon for the meridian system. Thus, acupuncture on $LI_4$ affects to thermal changes of the abdominal skin and $LI_4$ area, but exact examination of thermal changes on abdominal skin will have to be done.

The purpose of this study was to investigate physiological responses such as rectal temperature, skin temperature, micro climate, sweat rate and subjective sensations using cold protective clothing with five different clo value. The clo value was measured by thermal manikin in windless condition. Healthy five 20's males volunteered as subjects for wearing trial experiment. The climate chamber was controlled at $50^{\circ}C$, 65% RH. The experiment consisted of repeated exercise and recovery periods. We found that the higher clo value has, the higher mean skin temperature, micro climate and sweat rate show. They felt warm and wet with higher insulation clothing. Thermal comfort increased in the last recovery period after exercise. There was significant difference between five cold protective clothing. In correlation analysis of clo value, it showed that correlation coefficient(r) values were more than 0.8. Therefore, in terms of clothing insulation, we found that correlation between thermal manikin experiment and wearing trial experiment was high. Clothing insulation could be variable according to many factors such as body movement, covering area, clothing gap, layering and design. Considering the body movement, we thought that insulation measurement need to carry out both thermal manikin experiment and wearing trial experiment.

Background: From our clinical experience, there were some problems in paratracheal stellate ganglion block at 6th cervical level (C 6 SGB), for example, lesser change in blood flow of the upper extremity and more occurrence of hoarseness. This study was undertaken to compare the various effectiveness of C 6 SGB and paratracheal stellate ganglion block at 7th cervical level (C 7 SGB). Methods: Forty patients were equally divided into 2 groups. In the Group I, patients were undertaken C 6 SGB with 0.25% bupivacaine 6 mL and in the Group II, patients were undertaken C 7 SGB with 0.25% bupivacaine 6mL. The skin temperature of index finger was measured before and after SGB and the warm sensation on face and upper extremity, hoarseness and upper extremity paralysis were studied. Results: The skin temperature of index finger was increased significantly from $33.95{\pm}0.89^{\circ}C$ to $34.51{\pm}0.90^{\circ}C$ in the Group I and from $33.94{\pm}0.82^{\circ}C$ to $35.38{\pm}0.66^{\circ}C$ in the Group II (P<0.05) The increase of skin temperature of index finger after procedure was $0.56{\pm}0.09^{\circ}C$ in the Group I and $1.44{\pm}0.02^{\circ}C$ in the Group II. The increase of skin temperature of index finger in the Group II was more statistically significant than Group I (P<0.05). The occurance of hoarseness in the Group II was significantly less than in the Group I. There was no significant difference in warm sensation on face and upper extremity and paralysis of upper extremity in both Groups. Conclusions: C 7 SGB showed better sympathetic block effect on upper extremity than C 6 SGB and hoarseness did not occur in C 7 SGB.

Background: The authors have performed ultrasound-guided stellate ganglion block (SGB) in our clinic using a lateral paracarotid approach at the level of the 6th cervical vertebra (C6). Although SGB at C6 is a convenient and safe method, there are ongoing concerns about the weak effect of sympathetic blockade in the ipsilateral upper extremity. Therefore, ultrasound-guided SGB was attempted using a lateral paracarotid approach at the level of the 7th cervical vertebra (C7). This prospective study aimed to compare changes in skin temperature after SGB was performed at C6 and C7, and to introduce a lateral paracarotid approach for SGB. Methods: Thirty patients underwent SGB twice: once at C6 and once at C7. For every SGB, the skin temperature of the patient's hypothenar area was measured for 15 min at 1-min intervals. Skin temperatures before and after SGB and side effects were compared between C6 and C7 groups. Results: The temperature of the upper extremity increased after SGB was performed at C6 and C7. There were significant differences between mean pre-SGB and the largest increases in post-SGB temperatures ($0.50{\pm}0.38^{\circ}C$ and $1.41{\pm}0.68^{\circ}C$ at C6 and C7, respectively; p<0.05). Significantly increased post-SGB temperatures (difference > $1^{\circ}C$) were found in 5/30 (16.7%) and 24/30 (80%) cases for C6 and C7, respectively (p<0.05). There were no significant differences in side effects between SGB performed at C6 or C7 (p>0.05). Conclusion: The lateral paracarotid approach using out-of-plane needle insertion for ultrasound-guided SGB performed at C7 was feasible and more effective at elevating skin temperature in the upper extremity than SGB at C6.

In this paper, we propose a personalized cooling management system with thermal imaging camera. The proposed equipment uses a thermal imaging camera to control the amount of cold air and the system according to the difference between the user's skin temperature before and after the procedure. When the skin temperature is abnormally low, the cold air supply is cut off to prevent the possibility of a safety accident. It is economical by replacing the skin temperature sensor with a thermal imaging camera temperature measurement, and it can be visualized because the temperature can be checked with the thermal image. In addition, the proposed equipment improves the sensitivity of the sensor that measures the distance to the skin by calculating the focal length by using a dual laser pointer for the safety of a personalized cooling management system to which a thermal imaging camera is applied. In order to evaluate the performance of the proposed equipment, it was tested in an externally accredited testing institute. The first measured temperature range was -100℃~-160℃, indicating a wider temperature range than -150~-160℃(cryo generation/USA), which is the highest level currently used in the field. In addition, the error was measured to be ±3.2%~±3.5%, which showed better results than ±5%(CRYOTOP/China), which is the highest level currently used in the field. The second measured distance accuracy was measured as below ±4.0%, which was superior to ±5%(CRYOTOP/China), which is the highest level currently used in the field. Third, the nitrogen consumption was confirmed to be less than 0.15 L/min at the maximum, which was superior to the highest level of 6 L/min(POLAR BEAR/USA) currently used in the field. Therefore, it was determined that the performance of the personalized cooling management system applied with the thermal imaging camera proposed in this paper was excellent.

The experiment described in this paper focused on determining the effects of high-temperature(20$^{\circ}$) treatment of Satsuma mandarins, prior to their storage, on their color development and quality. High-temperature treatment promoted fruit skin color during the storage, decreased the weight loss regardless of their color at the time of their harvest and reduced the decay occurrence until the middle of March, but there was no difference between treatments after the end of March. There was a tendency of higher soluble solid and acid levels in the fruit when high-temperature treatment was applied but this difference was not significant.

Regardless of a patient's diagnosis, the care of his skin has been a primary concern of nurses throughout the years. Nurses has washed, dried, and rubbed the skin and have changed his position so as to keep the patient's skin in good condition and to protect him from pressure sores. However, we still find many-patients suffering from the pressure sores which may take many mothers or years of treatment and cost a lot to be repaired. In view of expensive cost for treatment of the sores and low ratios of nursing staff per patient for intensive nursing care, prophylaxis of the bed sores with sufficient aids is extremely important both for patients and for nurses. Therefore, the unique purpose of this study was to determine whether sponge is good enough to treat and prevent the pressure sore as compared with gel pad and sheepskin. Sixty patients in the age range of 15 through 45 who were in unconscious status or have difficulty of mobility were chosen between January and March of 1974 at Seoul National University Hospital. They were randomly assigned to each treatment and observed on every 4th day with regard to level of consciousness, status of mobility, moisture or dryness of the bed, general skin condition, intake of nutrition, vital signs and intervals of position change in comparison with the changes of skin over the bony prominences. The study results were reviewed in a statistical method analysis of valiance-to obtain the following findings: 1. There was no significantly different changes of skin over the sanctum or the trochanter in each group using get pad, sheepskin or sponge. It means that we may substitute sponge for expensive gel pad or sheepskin. 2. There was no significant difference among mean changes of patient's skin in relation to sheepskin, gel pad and sponge. 3. There was no significant changes of patient's akin in relation to level of consciousness, status of mobility, intake of nutrition, general skin condition, temperature, blood pressure or interval of position change. 4. There were no meaningful interactions between each treatment and level of consciousness, moisture or dryness of the bed, intake of nutrition, general skin condition, temperature or blood pressure. 5. Sheepskin and gel pad had significantly better influence on patients with limited mobility than on patients with immobility, and sponge on patients with immobility on than patients with limited mobility, 6. Sheepskin and sponge had meaningfully totter influence on patients changing position at below 2-hour interval, gel pad at 2-4-hour interval, sheepskin at 4-6-hour interval, and three of them at above 6-hour interval.
