The purpose of the present study was to explore the most effective body region and cooling temperature to alleviate heat strain of workers in hot environments. We developed liquid cooling hood, vest, sleeves and socks and applied the water temperatures of 10, 15, 20, and 25℃ through the liquid cooling garments in a hot and humid environment (33℃ air temperature and 70% RH air humidity). A healthy young male participated in a total of 16 experimental trials (four cooling garments × four cooling temperatures) with the following protocol: 10-min rest, 40-min exercise on a treadmill and 10-min recovery. The results showed that rectal temperature, mean skin temperature, and ratings of perceived exertion during exercise; heart rate and diastolic blood pressure during recovery; and total sweat rate were lower for the vest condition than other garment conditions(p < .05). However, there was no differences in mean skin temperature among the four cooling garments when we compared the values converted by covering area(%BSA). When we classified the results by cooling temperature, there were no consistent differences in thermoregulatory and cardiovascular responses among the four temperatures, but 25℃ water temperature was evaluated as being the most ineffective cooling temperature in terms of subjective responses. In conclusion, the results indicated that wearing cooling vest with < 20℃ cooling temperature can alleviate heat strain of workers in hot and humid environments. If the peripheral body regions are cooled with liquid cooling garments, larger cooling area with lower cooling temperature than 10℃ would be effective to reduce heat strain of workers. Further studies with a vaild number of subjects are required.

본 연구의 목적은 1) 캡사이신(75 mg), 세사민(30 mg), 그리고 카르니틴(900 mg) 복합성분(CCSC)이 에너지 대사조절자로서 열발생 교감신경활동과 관련된 자율신경활동을 향상시키는지, 2) 본 연구의 대상자들의 ${\beta}_3-AR$ 유전자 다양성이 자율신경활동에 영향을 주는지를 조사하였다. 7명의 대상자 ($24.7{\pm}1.8$세)가 이 실험에 자발적으로 참여하였다. 심박수변이성 파워스펙트랄 분석에 의해 평가된 심장 자율신경활동은 CCSC 섭취 전과 후 총 120분간 매 30분마다 5분간 측정하였으며, CCSC 또는 위약 (CON)그룹은 무작위로 대상자에서 섭취되었다. 본 연구의 결과에서, 총 대상자중, ${\beta}_3-AR$ 유전자CC 타입을 가진 대상자는 없었다 . 두 그룹간의 안정시 심박수에서는 유의한 차이가 없었다. 자율신경활동에서도 그룹간 차이는 없었으나, CCSC그룹에서 섭취전과 섭취 후 30분에서 총자율신경활동(TOTAL power), 부교감신경활동(PNS power), 그리고 교감${\cdot}$부교감 신경활동지수에서 유의한 차이를 보였다(p<0.05, respectively). 이상의 결과로서, 비록 각각의 성분들은 지방분해와 관련이 있다 할지라도CCSC의 섭취는 열생산 교감신경 자극에 영향을 주지 않았으며, 오히려 양 교감${\cdot}$부교감신경활동의 향상과 관련이 있다는 것을 시사하였다. 따라서 미래의 연구에서는 ANS 활동에 영향을 주는 유전적 다양성뿐만 아니라 운동능력 향상 보조물 그리고/또는 지방분해 효과를 위한 더 많은 복합 영양 성분이 연구되어야 할 것이다.

DSOM(Diagnosis System of Oriental Medicine) was made as a computerized assistant program for oriental medicine doctors to be able to diagnose with statistical basis. Then DSOM uses questionnaires filled out by subjects without enough explanatory guide. If the subject misunderstand the meaning of the passages, we might not rely on that result. So I designed this study to investigate the diagnostic correspondent rates between DSOM and practitioners. First, let the respondents answer to DSOM(DSOM-Ⅰ for the rest). After that, three doctors diagnosed the respondents and marked how much they had symptoms about 16 pathogenic factors in the score range 0${\sim}$5('0' means they didn't have that symptom, '1' means they had that symptom but mild, '3' means they had that symptom moderately, '5' means they had that symptom severely. And let the respondents answer to DSOM(DSOM-Ⅱ for the rest) again. Finally, we investigated the correspondent rates of diagnosis between DSOM-Ⅰ,Ⅱ and doctors'. We obtained conclusions as following. In the comparison of output frequency rate of the pathogenic factors, the difference between DSOM-Ⅰ and Ⅱ was 1%. In the correspondent rates of diagnosis between DSOM-Ⅰ,Ⅱ and doctors', In DSOM-Ⅰ and Ⅱ answered by subjects two times respectively, the correspondent rate was highest in insufficiency of Yang(陽虛) and liver(肝) as 93.2%, lowest in damp(濕) as 69.5% and showed 81.9% in all 16 pathogenic factors mean. In DSOM-Ⅰ and Ⅱ, and Doctors' diagnose, they showed the complete correspondent rates of 15.3${\sim}$61.0%, 15.3${\sim}$59.3% in individual pathogenic factor, 36.5%, 37.3% in all 16 pathogenic factors mean each, and within ${\pm}$1 errorrange, they showed the correspondent rates of 32.2${\sim}$93.2%, 35.6${\sim}$89.8% in individual pathogenic factor, 67.6%, 67.3% in all 16 pathogenic factors mean each, and within ${\pm}$2 error range, they showed the correspondent rates of 62.7${\sim}$98.3%, 71.2${\sim}$100% in individual pathogenic factor, 85.1 87.6%% in all 16 pathogenic factors mean each. In the correspondent rates of the severe case, In the cases that the Doctors' diagnostic score mean was over 3(the severity of disease is middle), there were deficiency of qi(氣虛), stagnation of qi(氣滯), blood stasis(血瘀), damp(濕), liver(肝), heart(心), spleen(脾) and they all showed the correspondent rates of over 60 except blood stasis(血瘀). In the cases that the weighed pathogenic factor was above 9, the correspondent rates were 50${\sim}$100%. deficiency of qi(氣虛), blood-deficiency(血虛), stagnation of qi(氣滯), blood stasis(血瘀), insufficiency of Yin(陽虛), insufficiency of Yang(陽虛), coldness(寒), heat (熱), damp(濕), dryness(燥), liver(肝), heart(心), spleen(脾), kidney(腎), phlegm(痰).

The purpose of this study was to measure the prevalence of urinary incontinence (UI), urologic symptoms, chronic health problems they have, and to explore whether the differences in incidence of UI ware by age, sex, voiding pattern, and chronic health problems. Method: 298 subject were selected, age range from 60 to 94 years residing in one city, in republic of Korea. Data was collected presence of UI, urologic symptoms, chronic health problems, knowledge, and the discomfort with incontinent. Collected data was analyzed with frequency, percentage, t-test, and $\chi$2-test. Result: The results of this study are as follows: 1. Mean age was 71.4 years. Prevalent rate of UI was 17.0%, woman showed more than man. 2. UI incidence was significant in age (t=7.84, p=.000), sex ($\chi$2 =9.47, p=.002), and voiding frequency ($\chi$2=18.34, p=.000). Also, UI incidence was significant relationship with chronic health problem of heart disease ($\chi$2 =10.65, p=0.001), hypertension ($\chi$2=4.04, p= 0.046) and respiratory problem ($\chi$2=9.67, p=0.002). 3. The UI was grouped into urgent incontinence (45%), stress incontinence (33%), and combined (22%). UI occurred during the daytime 48% and 17% at night. 4. Only 9.8 % of the UI seek advice and/or treatment for their symptoms, almost 90 % remained untreated due to lack of knowledge or improper information. 5. The discomforts due to their UI was no significant difference in their condition, the urgent use of the rest room, leaking urine, and nocturia. Conclusion: This study suggests that 1 year and 3 year follow-up study is needed to compare health status of UI. Also suggests intervention study for urologic discomfort of incontinent and behavioral education for the elderly are needed.

The present study was designed to clarify whether scuba diving at 5 meters of seawater influences cerebral hemodynamics, hematological and biochemical variables. Twenty healthy young men well trained scuba diving participated in this study. The blood flow velocity in the right and left middle cerebral arteries (L-MCAV and R-MCAV), blood pressure (BP), heart rate (HR), CBC and differential count, prothrombin time (PT), activated partial thromboplastin time (aPTT), biochemical variables, D-dimer and interleukin-8 (IL-8) levels were determined before, immediately after scuba diving for 30 min, and after 30 min of rest (Pre-scuba, Scuba and R-30m, respectively). L-MCAV and R-MCAV tended to increase, but the only significant increase was in L-MCAV in Scuba. SBP and HR significantly declined in R-30m compared with those of Pre-scuba and the Scuba. IL-8 levels were elevated in Scuba and R-30m compared with that of Pre-scuba. In Scuba and R-30m, hematological variables except PT and biochemical parameters excluding glucose and lactic acid did not significantly changed in comparison with those of Pre-scuba. PT level at Scuba and glucose level at R-30m significantly declined in Scuba, while lactate level at R-30m increased compared with each in Pre-scuba. However, PT level at Scuba was within a normal range. These results suggest that scuba diving at 5 m of seawater for 30 min has no adverse effects, is safe and useful for improving health. However, further study must be performed to clarify the mechanism of elevated IL-8 level following scuba diving.
