This study is the first part of the research to reveal the effects of somatotype characteristics on body temperature control reaction as well as thermal sensation. Nine healthy female collegians (classified into 3 body types of thin, normal, and obese according to Rohrer index) living in Busan were chosen as the subjects. The following are the results: Significant differences of skin temperature appeared in the parts of epigastrium (thin/normal>obese), anterior forearm (normal>thin/obese), and anterior leg (obese > thin/normal) as well as mean skin temperature. Mean skin temperature temporarily dropped owing to the exercise but tended to recover as time went by. Skin temperature of normal/thin shows higher than obese type. The change of skin temperature was noticed in the order of forehead > epigastrium > anterior forearm > anterior leg > anterior thigh (obese type) ; epigastrium > forehead > anterior forearm > anterior thigh > anterior leg (normal type) ; epigastrium > forehead > anterior forearm > anterior thigh > anterior leg (thin type, before and after exercise); epigastrium > forehead > anterior forearm > anterior leg > anterior thigh (thin type, during exercise). Significant differences were shown in the temperature change inside clothes according to somatotypes. No significant differences were revealed in thermal sensation, moisture sensation, and comfortable sensation according to body types and time.

자연광은 시시각각 변화하며 광 특성의 변화는 계절별 시간별 일주기리듬을 갖는다. 이러한 자연광의 리듬은 인간의 감성 또는 수면-각성 패턴과 같은 생체리듬에 영향을 미친다. 인간의 생체리듬은 멜라토닌에 의해 조절되며 특히, 수면-각성주기를 일정한 수면패턴으로 유지하게 한다. 이에 본 논문에서는 자연광의 하루 주기변화에 따라 조명의 단파장 영역 중 446nm~477nm의 비율을 제어하여 심부 체온의 변화를 통해 수면패턴을 분석한다. 분석결과, 자연광의 일몰시간과 유사한 시점에서 446nm~477nm의 비율을 최소로 제어 하였을 때 수면에 긍정적인 영향을 미치는 것을 확인하였다.

50 days old, 4.5kg male patient was admitted at department of pediatrics due to congenital heart disease with congestive heart failure. The echocardiographic finding was perimembranous type ventricular septal defect. The patient underwent open heart surgery for patch closure of VSD. Immediately postoperatively, junctional ectopic tachycardia developed and the patient was in hemodynamically unstable state with decreased urine output. We used inotropics, digitalis and diuretics, however these treatments were not effective in recovering the unstable state. Therefore, we tried a mild hypothermic treatment(34℃). During the POD #2, mild hypothermia method was repeated four times. The junctional ectopic tachycardia was converted to normal sinus rhythm, hemodynamic state was stable, and urine output was increased. The patient was discharged at POD #8.

The present study was designed to observe the thermal dynamics of core and skin temperatures during sub-maximal treadmill exercise; to investigate the effect of regional body cooling during short rest after the treadmill exercise on the thermal dynamics. Three conditions (No cooling, Head/Hand cooling, Leg cooling) were simulated in a climatic chamber at 24±1℃ and 50±5%RH. Subjects performed two bouts of treadmill exercise at a rate of 80%HR_max followed by rest. Body cooling with a hood, long gloves, and a blanket that circulated water set at 15℃ was assigned during two bouts of rest. The results showed that (1) rectal temperature (T_re) did not show significant difference between three conditions; (2) Skin temperatures had specific features, depending on body regions. In particular, the initial fall phenomena of skin temperatures at the onset of exercise were noteworthy in the chest, thigh, calf, and finger tip. Of these, the most significant initial fall was found in finger temperature (T_fing). (3) During the period of the initial fall in skin temperatures, T_re gradually increased. (4) The magnitude of the fall of T_fing at the onset of 2^nd running was on average 4.8, 5.1 and 3.4℃ for Control, HH cooling, and Leg cooling, respectively (p<0.05). The initial drop of T_fing at the onset of running was maintained for an average of 8.1, 7.9 and 6.3 minutes for Control, HH cooling, and Leg cooling, with no significant differences. In conclusion, the initial fall phenomena at the onset of treadmill exercise reflected non-thermal factors, as opposed to internal thermal status. The magnitude of the initial fall in T_fing was affected by legs cooling. Therefore, the initial fall phenomenon should be considered when interpreting the thermal status of the shell during heavy works/exercises that assigned with intermittent regional body cooling.

Background : The thoracic and thoracoabdominal aortic surgery is a complicated procedure that has various method of approach and protection. The authors have performed several methods to treat these diseases. Therefore, we attempt to analyze their results and risks. Material and Method: From June of 1992 to August of 2001, we performed 26 cases of thoracic aortic surgery and 10 cases of thoracoabdominal aortic surgery. There were 17 aortic dissections, 17 aortic aneurysms, one coarctation of aorta and one traumatic aortic aneurysm. The thoracic aortic replacement was performed under a femorofemoral bypass, an LA to femoral bypass, or a deep hypothermic circulatory arrest. The thoracoabdominal aortic replacement was performed under a femorofemoral bypass or a pump assisted rapid infusion. Result: There were 7 renal failures, 11 hepatopathies, 7 cerebral vascular accidents, 2 heart failures, 5 respiratory insufficiencies, and 2 sepsis in postoperative period. There were 9 hospital mortalities which were from 2 bleedings, 2 heart failures, 2 renal failures, a sepsis, a respiratory failure, and a cerebral infarction. There were 3 late deaths which were from ruptured distal anastomosis, cerebral infarction, and pneumonia. Conclusion: Deep hypothermic circulatory arrest was not good supportive methods for thoracic aortic replacement. Total thoracoabdominal aortic replacement was a high risk operation.

In this study, We investigated the effect of foot cooling on the reduction of body temperature after hard exercise at the high temperature of $40^{\circ}C$. We performed a total of 30 subjects, and the subjects performed treadmill exercise for 30 minutes. We produced the cooling device to cool the foot using Peltier module. After the end of the exercise, We performed normal recovery method and cooling recovery method(one foot, both feet) for 1 hour on the same indoor environmental conditions and confirmed the change of body temperature of subjects. The results of deep body temperature measurement showed average $38.78{\pm}0.22^{\circ}C$ to $38.54{\pm}0.15^{\circ}C$ when the normal recovery method was performed. Cooling recovery method on one foot showed average $38.69{\pm}0.14^{\circ}C$ to average $38.06{\pm}0.17^{\circ}C$ and Cooling recovery method on both feet showed average $38.69{\pm}0.15^{\circ}C$ to average $37.84{\pm}0.21^{\circ}C$. There was a significant difference between the normal recovery method and the one foot cooling recovery method(p < .05), there was a significant difference between the normal recovery method and the both feet cooling recovery method(p < .05) and there was a significant difference between the one foot cooling recovery method and the both feet cooling recovery method(p < .05). Body temperature showed the lowest decrease rate when the normal recovery method was performed, and body temperature showed the highest decrease rate when the both feet cooling recovery method was performed. Therefore, recovery of cooling on the foot after hard exercise have decreased body temperature, delay fatigue in the body, and will be contributed to improvement of athlete performance.

Parturition is an important event for farmers as it provides economic gains for the farms. Thus, the effective management of parturition is essential to farm management. In particular, the unit price of cattle is higher than other livestock and the productivity of cattle is closely associated to farm income. In addition, 42% of calving occurs in the nighttime so accurate parturition predictions are all the more important. In this paper, we propose a method that accurately predicts the calving date by applying core body temperature of cattle to deep learning. The body temperature of cattle can be measured without being influenced by the ambient environment by applying an ingestible bio-sensor in the cattle's rumen. By experiment on cattle, we confirmed this method to be more accurate for predicting calving dates than existing parturition prediction methods, showing an average of 3 hour 40 minute error. This proposed method is expected to reduce the economic damages of farms by accurately predicting calving times and assisting in successful parturitions.

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.

Dimorphic fungi are characterized by the production of mycelia in the environment or when incubated at lower temperatures ($25{\sim}30^{\circ}C$) on media. The conversion to yeast occurs when invading a human body or when incubated at elevated temperatures ($35{\sim}37^{\circ}C$). Dimorphic fungi cause systemic infection and occur only in endemic regions; they can cause deep mycosis, which invades tissues and organs. Imported thermally dimorphic fungal pathogen has five genera, such as Coccidioides immitis, Histoplasma capsulatum, Blastomyces dermatitidis, Talaromyces (Penicillium) marneffei, and Paracoccidioides brasiliensis. Thus far, 30 cases of dimorphic fungi have been reported in Korea, including C. immitis in 18, H. capsulatum in 5, B. dermatitidis in 3, and T. marneffei in 4 cases. Three 3 cases of C. immitis, 2 cases of H. capsulatum, 1 case of B. dermatitidis, and 1 case of Talaromyces (Penicillium) marneffei were reported in Korea, even though no experience of an epidemic was present. None the dimorphic fungi except for Sporothrix schenkii (Dimorphic fungi) occur in Korea but are caused by endemic fungi that can be found only in specific regions and limited areas of foreign countries. Considering the trends of migratory locals and the increasing number of immigrants living in and returning home, the incidence of imported infections is expected to increase.
