  • Purpose: The purpose of this study is to find the factors that can affect the assessment on severity of cold hypersensitivity on hands and feet by comparing the temperature distribution among the seasons, the scan time and the laboratory temperature. Methods: We compared the temperature distribution of the arms and legs, according to the season and scan time on the basis of the results of Digital Infrared Thermal Imaging(DITI) conducted on 178 women who visited the hospital in summer and winter. We evaluated the correlation between the laboratory temperature and temperature distribution of the arms and legs. Results: The temperature distribution of the arms and legs was significantly different between summer and winter. The temperature distribution of the arms and legs was not significantly different according to the scan time. There was no significant correlation between laboratory temperature and the temperature distribution of the arms and legs in summer and winter. Conclusions: The diagnostic criteria to assess the severity of cold hypersensitivity on hands and feet need to be changed according to the season. The scan time and the small variation($24^{\circ}C{\sim}27^{\circ}C$) of the laboratory temperature doesn't affect the assessment of severity of cold hypersensitivity.

  • Objectives: This study aims to research correlation of the malondialdehyde level in urinalysis with cold hypersensitivity. Methods: We studied 128 patients visiting ${\bigcirc}{\bigcirc}$ Korean Hospital from March, 2013 to May, 2013. The subjects were categorized into two groups: cold hypersensitivity group (n=46) and control group (n=79). Patients in cold hypersensitivity group had been stressed because of severe cold hypersensitivity. First, We investigated the difference of the level of malondialdehyde between two groups. In addition, temperature of the two points, ST32 and LR3, was measured by using Digital Infrared Thermal Imaging (DITI) to find out whether the extent of cold hypersensitivity is related to the level of malondialdehyde. Results: There is no different characteristics between two groups. The average of malondialdehyde in cold hypersensitivity group ($1613.15{\pm}1260.71$) is significantly higher than in control group ($1170.01{\pm}1015.66$)(p=0.04). But there is no correlation between level of malondialdehyde and the extent of cold hypersensitivity (r=-0.22, p=0.13). Conclusions: Although the level of malondialdehyde in cold hypersensitivity group is higher than in control group, there is no significant correlation between level of malondialdehyde and the extent of cold hypersensitivity.

  • Building Information Modeling (BIM) is increasingly used throughout the facility's life cycle for various applications, such as design, construction, facility management, and maintenance. For existing buildings, the geometry of as-built BIM is often constructed using dense, three dimensional (3D) point clouds data obtained with laser scanners. Traditionally, as-built BIM systems do not contain the material and textural information of the buildings' elements. This paper presents a semi-automatic method for generation of material and texture rich as-built BIM. The method captures and integrates material and textural information of building elements into as-built BIM using thermal infrared sensing (TIS). The proposed method uses TIS to capture thermal images of the interior walls of an existing building. These images are then processed to extract the interior walls using a segmentation algorithm. The digital numbers in the resulted images are then transformed into radiance values that represent the emitted thermal infrared radiation. Machine learning techniques are then applied to build a correlation between the radiance values and the material type in each image. The radiance values were used to extract textural information from the images. The extracted textural and material information are then robustly integrated into the as-built BIM providing the data needed for the assessment of building conditions in general including energy efficiency, among others.

  • The clinical data and thermographic imaging were analyzed on the 100 cases of Bell's palsy who were treated in the Kwang-Ju Oriental Medical Hospita! of Wonkwang University from February to October 1997. All the cases were taken Digital Infrared Thermograph Imaging(DITI) before treatment and 30 cases of them were taken follow up imaging again after recovery. And the following results were obtained. 1. Of 100 cases, under teenager occupied $1\%,\;teenager\;8\%,\;2nd\;decade\;14\%,\;3rd\;decade\;11\%,\;4th\;decade\;16\%,\;5th\;decade\;26\%,\;6th\;decade\;16\%,\;7th\;decade\;7\%\;and\;over\;80\;occupied\;1\%$. 2. Male occupied $48\%$ and female occupied $52\%$. 3. $42\%\;of\;male\;and\;23\%$ of female had the affected side at left side. And right facial nerve palsy occured at $29\%\;of\;male\;and\;29\%$ of female. 4. The most common cause of Bell's palsy was cold wind $18\%$, and the next were excessive labor $15\%,\;stress\;12\%,drinking\;2\%\;and\;cold\;food\;1\%$. 5. Thermal pattern were present as hyperthermal pattern in $44\%$ and hypothermal pattern in $22\%$. 6. The DITI showed hyperthermal pattern as close as to the onset day and changes to hypothermal pattern as times passed. 7. The DITI pattern and post-auricular pain, the most common prodomal syndrome, showed no significant relationship. 8. The relationship between the grade of paralysis and thermal patttern of DITI showed no significance. 9. Mean temperature of loci in affected side indicrtted $30.27^{\circ}C\;at\;Yang\;baek,\;30.02^{\circ}C\;at\;Taeyang,\;29.25^{\circ}C\;at\;Geoyo,\;29.62^{\circ}C\;at\;Jichang,\;29.78^{\circ}C\;at\;Hakwan,\;29.61^{\circ}C\;at\;Hyupgeo,\;and\;30.59^{\circ}C$at Yeopoong. 10. Mean temperature of loci in unaffected side showed $30.16^{\circ}C\;at\;Yang\;baek,\;30.02^{\circ}C\;at\;Taeyang,\;29.61^{\circ}C\;at\;Geoyo,\;29.68^{\circ}C\;at\;Jichang,\;29.70^{\circ}C\;at\;Hakwan,\;29.57^{\circ}C\;at\;Hyupgeo,\;and\;29.89^{\circ}C$at Yeopoong. 11. Of 30 cases who were taken follow up imaging again after recovery, the relationship between delta T at loci and symptoms showed no significance.

  • To investigate the effects of facial blood flow rates(FBFR) and facial skin temperature(FST) generated by Gagam-Jawoonaek(GJ) application(appl.) after Miso Facial Rejuvenation Acupuncture(MFRA). Ten people in their twenties to fifties with no skin diseases were recruited. We randomly divided subjects two groups(A, B) and set the GJ appl. site(group A - right side, group B - left side). MFRA was performed on both sides of their face. Immediately after acupuncture treatment(AT treat.), GJ was applied only half of the face. We measured their FBFR using Laser Doppler Perfusion Imaging(LDPI) and FST using Digital Infrared Thermal Imaging(DITI) at pre-AT treat., immediately after AT treat., twenty and sixty minutes after GJ appl.. We analyzed data using Mann-Whitney test and Wilcoxon test(p < 0.05). After MFRA treat., FBFR on both sides increased. Twenty minutes after JW appl., the changes of FBFR on GJ appl. side($122.9{\pm}43.1PU$) were bigger than GJ non-appl. side($80.9{\pm}38.4PU$), a statistically significant decrease. Sixty minutes after application, FBFR on both sides were recovered almost at the same level as that of pre-AT treat. After MFRA treat., FST on both sides increased. Twenty minutes after GJ appl., the changes of FST on GJ appl. side($1.1{\pm}0.6^{\circ}C$) were comparable to that of GJ non-appl. side($1.2{\pm}0.5^{\circ}C$). Sixty minutes after application, FST on both sides were recovered almost at the same level as that of pre-AT treat.. Gagam-Jawoonaek could decrease facial blood flow rates.

  • Objectives : To observe the effect of acupuncture treatment on Digital Infrared Thermographic Imaging(DITI) in frozen shoulder patients. Methods : 17 voluntary patients received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The patients were instructed to practice self exercise during their daily lives. Evaluations were made before treatment, after 1 week of treatment, after 2 weeks, 3 weeks and after 4 weeks of treatment. Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI), Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). DITI was measured before treatment and after 4weeks of treatment. The obtained data was analyzed. Results : CSA, SPADI, VAS, adduction and extension showed significant(p<0.05) improvement. Abduction and flexion both improved after 4 weeks of treatment, but the improvement was statistically insignificant(p>0.05). DITI showed improvement but the improvement was insignificant(p>0.05). Conclusion : 4 weeks of acupuncture treatment significantly improved CSA, SPADI, VAS, adduction and extension in frozen shoulder patients(p<0.05). The improvement of abduction and flexion after 4 weeks of acupuncture treatment was insignificant(p>0.05). DITI results improved after 4 weeks of acupuncture treatment. But the change of thermal difference was insignificant(p>0.05).

  • 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.
