This study was carried out to assess the usefulness of thermography for diagnosis and healing process of musculoskeletal disorder in horses. Horses with experimentally induced infectious arthritis were treated with bee venom or antibiotics for 5 weeks from 24 hours after inoculation of Staphylococcus aureus, the effectiveness of the 2 therapeutic drugs treatment was similar to each other. Thermographic evaluation was similar to any other tests, because the thermal pattern tend to return to normal with declining similar to those of clinical signs, laboratory experiments and healing of the lesion. This ability to assess inflammatory change noninvasively make thermography an ideal imaging tool to aid in the diagnosis of certain lameness condition or musculoskeletal disease in horses. These results suggested that thermographic evaluation in horses with musculoskeletal disorders were useful for diagnosis and helpful for monitoring of healing process.

Thermography is a diagnostic procedures that measures infrared energy emitted by the skin. Thermography detects body temperature change which are controlled by the autonomic nervous system. It does show the thermal dysfunction that correlates closely with pain syndromes as well as normalization when the healing process takes place. Experienced clinical interpretation of the thermal pattern is necessary to diagnose and establish causation. Thermography is useful in the diagnosis of painful conditions such as herniated disc diseases, myofascial syndrome, myositis, musculoligamentous injury, reflex sympathetic dystrophy, athretic injuries, vascular diseases, arthritis, inflammation and breast tumors.

The purpose of this study was to verify human physiological responses to emotional lighting system using LED (light emitting diode) flat lighting. Subjects were ten males in their twenties without medical history to eyes. Colors of LED lighting are red, orange, yellow, green, blue, purple and colorless (white). They were stimulated by LED lighting for 5 minutes. We measured body temperature, heart rate variability (HRV) and electroencephalogram (EEG) before and after color stimulus. In case of EEG analysis, relative power ${\alpha}$ wave ratio decreased in the groups of colorless, red and orange color light. Also, sympathetic nerve was more activated than parasympathetic nerve and the body temperature was increased in the groups of colorless, red, orange, yellow color light. On the other hand, relative power ${\alpha}$ wave ratio increased and parasympathetic nerve was more activated than sympathetic nerve and the body temperature was decreased in the groups of green, blue and purple color light. The results imply that the LED color lighting system in the realistic experiment environment. In the future, studies with compounded both colors and modes according to situation or auditory as nature sound or olfactory as aroma will be required.

Purpose: This study is to assess oriental medicine treatment for cervical sprain from traffic accident using DITI. Methods: 21 patients who hospitalized in the Kangnam Korean Hospital, KyungHee Univ. from March 1, 2004 to September 30, 2005 diagnosed as cervical sprain from traffic accident were participated in this study. They received acupuncture treatment, Herb medicine, ICT-Tx, and Nega-Tx during the admission period. We checked temperature of neck(A area) and whole back(B area) and ${\Delta}T$ were calculated at admission date(pre-Tx group, ${\Delta}T1$) and discharged date(post-Tx group, ${\Delta}T2$). Results: ${\Delta}T2$ decreased significantly in post-Tx group compared with ${\Delta}T1$ in pre-Tx group Conclusion: Oriental medicine treatment can be the effective way to treat cervical sprain from traffic accident. and DITI can be useful instrument to assess oriental medicine treatments.

The present study is aimed to investigate the effect of the safety hat on the balance of body temperature by observation of the physiological response under hot working environment. The experiment was carried out in a climate chamber of 3$0^{\circ}C$, 50%RH for 70 minutes. To compare the two kinds of safety hat, 5 healthy male subjects worn safety hat without hole (called 'without hole') or safety hat with hole (called 'with hole') according to a randomized cross-over design. The main results of this study are as fellows: Rectal temperature and heart rate were significantly lower level in 'with hole'than in 'without hole'. The mean skin temperature was significantly higher in 'without hole'than in 'with hole'. Blood pressure were significantly low in 'with hole'. Sweat rate which was measured by weight loss before and after experiment was higher in 'without hole'. In subjective ratings, subjects replied more hot, more uncomfortable and more wet, they felt more fatigue in condition of 'without hole'. Work ability which was measured by a grip strength dynamometer was higher in 'with hole'. Safety hat which can be used for safety of the brain in work place is meaningful device of behavioral thermoregulatory response under the hot working environment. The safety hat which is designed for proper ventilation and hygiene can maintain the homeostasis of body temperature by releasing body temperature efficiently.

Most of the existing multicast routing protocols for ad-hoc networks do not take into account the efficiency of the protocol for the cases when there are large number of sources in the multicast group, resulting in either large overhead or poor data delivery ratio when the number of sources is large. In this paper, we propose a multicast routing protocol for ad-hoc networks, which particularly considers the scalability of the protocol in terms of the number of sources in the multicast groups. The proposed protocol designates a set of sources as the core sources. Each core source is a root of each tree that reaches all the destinations of the multicast group. The union of these trees constitutes the data delivery mesh, and each of the non-core sources finds the nearest core source in order to delegate its data delivery. For the efficient operation of the proposed protocol, it is important to have an appropriate number of core sources. Having too many of the core sources incurs excessive control and data packet overhead, whereas having too little of them results in a vulnerable and overloaded data delivery mesh. The data delivery mesh is optimally reconfigured through the periodic control message flooding from the core sources, whereas the connectivity of the mesh is maintained by a persistent local mesh recovery mechanism. The simulation results show that the proposed protocol achieves an efficient multicast communication with high data delivery ratio and low communication overhead compared with the other existing multicast routing protocols when there are multiple sources in the multicast group.
