Objectives:The Implicit Association Test (IAT) is a paradigm designed to assess individual difference in implicit cognition. This study investigated the difference of IAT effect of alcohol related pictures and words in alcohol dependent patients, heavy drinkers and control subjects. Methods:23 alcohol dependence patients, 23 heavy drinkers and 22 controls were included. All subjects per-formed two IAT, one of which was composed of alcohol related pictures and the other was made of words. Results:Repeated measurement ANOVA showed significant main effect of ‘Type of stimuli’ [F(1,65)=29.38, p<0.001], and IAT effect was more prominent by words than pictures. But there was no significant interaction of ‘Type of stimuli’ and ‘Group’ [F(1,65)=1.466, p= 0.238]. In between group analysis, there was the significant main effect of ‘Gorup’ [F(2,65)=4.007, p=0.023], and control group had significantly negative implicit cognition to alcohol than heavy drinker group. Conclusion:IAT effect was marked in alcohol related word than picture. But IAT effect pattern of each group was not changed by stimulus. Overall alcohol related word and picture show difference in IAT effect power but both alcohol related picture and word IAT was useful for estimate alcohol related implicit cognition.

Objective : The Asbestos has been widely used in various occasions because of its superior physical properties with small expenses. But it has been associated with malignant mesothelioma or lung cancer with relatively long latency period. Use of asbestos was banned worldwide since 1980s. In Korea, the products with asbestos contents exceeding 1 % of total weight should be treated with caution by the authorized specialists. Because there are increasing concerns about the health risks associated asbestos dispersion during the renewal or dismantlement, we tried to elucidate the potential hazard of the military facilities in the ROK army. Method : The solid samples were analyzed by PLM(Polarized Light Microscope) and the airborne samples were analyzed by PCM(Phase Contrast Microscope). Results : Asbestos were found in 307(82.7%) out of total 371 samples. The 307 samples were chrysotile. A result of airborne asbestos was 0.521ea/㎤ of the 9 samples at a warehouse, which exceeds the exposure level(0.1ea/㎤). Conclusion : The exposure to the asbestos is rarely occurred during the ordinary activities. But the possibility of asbestos exposure increases during renewal or dismantlement or damage of the facilities. Therefore, to protect the health of the soldiers from the asbestos exposure, we should concentrate our efforts to find the hazardous places and to control the risks.

Objective : IAQ(Indoor Air Quality) was measured during normal and training periods in military bunkers. This study was done to protect the health of workers and to improve indoor air quality. Method : We tested CO2, PM10, Total air borne microbes, Temperature and relative humidity during normal and training times. They were easily affected by human activity. We checked to see concentrations varied by time. Results : Training periods were statistically significant higher than normal(p<0.05). The highest concentrations were between 2∼4 p.m. Conclusion : Bunkers were highly contaminated by CO2 during military training. That means these was deficient ventilation. Therefore, highly contaminated locations and times is needed purification of IAQ. The IAQ measurement law is needed for some military facilities and bunkers.

Objective : The purpose of this study was to protect the health of workers from radon hazards in military facilities Method : We chose 5 units and measured radon concentration in military bunkers from August, 2012 to November, 2012. The α-track was used to measure radon concentration. Results : The highest concentration of mean was 7.16±3.09 pCi/ℓ and the highest concentration was 18.12 pCi/ℓ(p<0.01). The exceed rate of radon was 5.9~89.4% by comparison recommended level. The mean of respective sites were 4.18±3.10 pCi/ℓ at basement facilities, 2.33±1.03 pCi/ℓ at 1st floor, 1.86±0.71 pCi/ℓ at 2nd floor(p<0.01). Conclusion : We should measure the radon concentration broadly in military facilities for other units. To protect workers health, we must make an effort to reduce radon concentration by ventilation and construction work in military bunkers.
