콘크리트에 매입된 철근의 정량적인 부식률을 측정하기 위해 적외선 열화상법을 이용하였다. 적외선 촬영 실험에서는 부식률(0, 1, 3, 5, 7, 10%)과 대기온도(16, 21, 25, $28^{\circ}C$), 피복두께(10 mm, 20 mm, 30 mm)에 변수를 주어 콘크리트 표면온도를 측정하였으며, 콘크리트 표면온도의 초기 온도상승률에 대해서 측정결과를 분석하여 다음과 같은 결론을 얻었다. 적외선 촬영으로 얻어진 열화상 정보는 서로 다른 부식률과 피복두께에서는 현저한 차이를 보였으나 대기온도에 대해서는 그 영향이 미비하게 나타났다. 철근의 부식률에 따른 열 발생량이 콘크리트 표면온도에 부식률에 비례하여 열을 발생시킴으로써 철근의 부식률을 정량적으로 평가할 수 있는 분석기법을 연구하였다.

Objectives : The aim of this study is to validate the correlation between Assessment Instruments of Knee OA and digital infrared thermographic imaging(DITI) and to find out the methods to assess knee OA by DITI. Methods : 60 subjects were evaluated. They were asked to answer VAS pain scale, WOMAC, KHAQ and LFI. Correlation was assessed by examining the spearman's rank correlation coefficients. Results : VAS, WOMAC and LFI was correlated with not only the thermal difference between Ant. knee and Post. knee, but also the lowest temperature of Ant. knee. Conclusion: DITI value was useful for evaluating the degree of OA. And we should find out that decrease of pain is correlated with change of DITI value.

Objective : The purpose of this study is to report the patient with peripheral neuropathy, who improved by Oriental medical treatment. Methods : The patient was managed by acupuncture, moxibustion, physical treatment and herbal medicine. We checked digital infrared thermographic imaging(D.I.T.I.), electromyography(E.M.G.), nerve conduction velocity(N.C.V.), deep tendon reflex(D.T.R.), sensory recover area and range of motion(R.O.M.) of knee & ankle. Results : After 6 week treatment, clinical sign(the movement and sense of leg) of improvement was appeared. Also E.M.G., N.C.V., D.T.R. and D.I.T.I. was recovered to nearly normal range. Conclusion : The results suggest that combination of acupunture, moxibustion and herbal medicine is good method for treatment of peripheral neuropathy. But further studies may be required to concretely prove the effectiveness of this methods for treating peripheral neuropathy.

Backgroud and Objectives： Because the pain is subjective in human, we frequently need the objective tool for estimation of pain. The Visual Analog Scale (VAS) is a method for pain grading, but it is also a subjective method. The purpose of this study is to seek an objective method for measurement of pain. Author suggests that the estimation of local body temperature may be associated with the severity of pain in tonsillar disease and the change of it measured by Digital Infrared Thermographic Imaging (DITI), may also be correlated with the change of pain. Materials and Method : Four groups were selected and measured for VAS and body temperature in DITI. Group A and B were post-tonsillectomy groups divided by age. Group C was acute tonsillitis group. Group D was peritonsillar abscess group. Results : In Group A and B, the subjective VAS was significantly correlated with objective local body temperature (correlation coefficient r=0.673, 0.647) and significant correlation was also present in acute tonsillitis and peritonsillar abscess groups(r=0.596,0.642). Conclusion : The change of pain was strongly associated with that of local body temperature in tonsillar disease. DITI is a useful method for objective grading of pain and can be used for the study of postoperatve pain and effectiveness of pain control.

Nowadays Aromatherapy has been proved its own superiority and is getting popular for its specipic effects. Then, we can find some of aroma herbs are similar to those of Oriental medicine herbs. The purpose of this study was to identify the heating effect in Fennel essential oil on Aromatherapy, which is known for an effect of Hui-Hyang(Foeniculm vulgare) on Oriental medicine. We studied a patient who has visited Dongseo Oriental Hospital with Handam From November 29th 2001 to April 12th 2003 and has been observed for 5 months. We chose three spots in his body where the temperatures were lower than the other sides over $0.4^{\circ}C$. Then we treated him only with Fennel essential oil for 20 days. We used Digital Infrared Thermographic Imaging to analyze the symptoms and assess the results of treatment. The results we obtained were as follows; 1. Fennel essential oil showed the heating effect at all the three spots on the Handam patient. 2. Fennel essential oil has the characteristics of Warmness and Heat in Oriental Medicine. 3. More studies are needed to analyze what kind of characteristics Other essential oils have by Oriental medical thought for better clinical use in Oriental Medicine.

Purpose : This study was performed to evaluate the efficacy of herb medicine on climacteric woman with numbness of lower limbs by using Digital Infrared Thermographic Imaging(DITI). Methods : The patient was 56-year-old female who was suffering from numbness, cold hypersensitivity of lower limbs and hot flush. We treated her using herb medicine, acupuncture and moxibustion. The progress of symptoms were evaluated by DITI, and then we compared DITI before treatment and after treatment. Results : After treatment, visual analog scale of numbness and cold hypersensitivity of lower limbs were decreased and frequency of hot flush was also decreased. The temperature of forehead got lower than that before treatment and the temperature of LR3 and ST32 got higher than those before treatment on DITI. Conclusion : This result suggest that DITI can be used for assessment after treatment on climacteric symptoms with numbness of lower limbs.

Purpose : The purpose of this study is to report the effect of Traditional Korean Medicine(TKM) on amenorrhea which oligomenorrhea has become worse. and to investigate the change of body temperature measured by Digital Infrared Thermographic Imaging(DITI). Methods : The patient in this case was 29-year-old female. The chief complain was amenorrhea which oligomenorrhea has become worse. We treated her by TKM. and evaluated the progress of symptoms by DITI. And then We compared DITI before treatment and after treatment. Results :After TKM treatment. the differences of temperature between Indang(印堂) and the four abdominal sites(CV4,6,12,17) were decreased on DITI. respectively. Conclusion : TKM treatment is effective on amenorrhea which oligomenorrhea has become worse. And DITI could be useful to assess the amenorrhea objectively. But more research should be needed.

This study is designed to compare the effect of a needle with the magnet on body. We took the skin temperature of the belly with digital infrared thermographic imaging while we sticked needle and apply magnets on L14. We made experiments on 40 healthy male volunteers for one month. We classified control group not acupuncture or magnet adhering(CON). acupuncture group on left and right L14(LA). and the permanent magnet group adhering to left and right(LM). And LM is divided into S-polar permanent magnet group(LMS) and N-polar permanent magnet group adhering to left and right L14(LMN). When we observed that temperature changed with time, the skin temperature of th belly in CON descended significantly but LM, LMS and LMN is not changed significantly. As mentioned above. we observed that the needles on L14 affected the change of temperature on the belly, and conjectured that the appliance of magnets had the same results. If the mechanism depends on the meridian of body and energy. we suppose that the appliance of magnets and needles has same effects.

Objective : There is still debate about the diagnostic efficacy of digital infrared thermographic imaging[DITI], nevertheless, it has been used for the diagnosis of carpal tunnel syndrome[CTS]. We performed comparative study between patient and control groups to investigate the diagnostic value of DITI in CTS. Methods : We studied 27 patients with electrodiagnostically-proven CTS and 18 symptom-free volunteers as a control. We measured thermal difference on DITI in the corresponding regions of the hands and forearms. We statistically analyzed the thermal data using a t-test. Results : The average thermal difference in the diagnosed patient group ranged from $0.0303^{\circ}C$ to $0.2856^{\circ}C$, while that in control group ranged from $0.0611^{\circ}C$ to $0.2878^{\circ}C$. In the CTS patient group, thermal difference between each 2nd finger was higher than that of other regions. However, there was no statistical significance between patient and control groups. Conclusion : We found that the diagnostic value of DITI in CTS was not sufficient. There should be a reconsideration of the usefulness of DITI in CTS.
