This study investigated mean airborne CO concention of 15 workplaces, suspected of CO exposure and conducted self-reported questionnaire completion and indirect COHb concentration measure using Micro II Smokerlyzer to healthy 702 adult subjects from 1999 May to 1999 September in order to find a relation of CO exposure and occupational factors, socioeconomic factors, and health related behaviors and confirm the related conditions in the screening test for CO exposure. The results of this study were summarized as follows : 1. In the CO exposed and non exposed group, COHb concentrations of the smokers were 2.55±0.96% and 2.21±0.97% and that got a statistically significant difference, There were not statistically significant differences in the age and total smoking index. Passed times after the last smoking, Working time/day, and working duration were statistically significant difference (p〈0.05). 2. In the CO exposed and non exposed group, COHb concentrations of non-smoking group were 0.94±0.35% and 0.68±0.47% and that got a statistically significant difference. There were not statistically significant differences in the age and working duration but Working time/day was a statistically significant difference(p〈0.05). 3. In the CO exposed group, r-square of multiple regression of the smokers was 38.5 % and passed time after the last smoking, working time/day, and job category were statistically significant differences (p〈0.05). And r-square in the CO non-exposed group was 38.3 % and age, passed time after the last smoking, and total smoking index were statistically significant difference. 4. In the CO exposed group, r-square of multiple repression of the non-smokers was 66.3% and job category and airborne CO concentration were statistically significant differences(p〈0.05). But r-square of non-smokers in the CO non-exposed group was 1.0% and there was not a statistically significant difference(p〈0.05). 5. In the smokers of CO exposed and non exposed groups, relation of COHb concentration and passed time after the last smoking was expressed as exponential function, Y = 2.9182e-0.0083x and r-square of this function was 37.4%. Therefore it was more than 150 minutes that passed time after the last smoking was when COHb concentrations were measured as less than 1%. In conclusion, variable, that was statistically significant to COHb concentraion in the both CO exposed and non-exposed smokers, was a passed time after the last smoking. We suggest that you have to restrict the smoking of smokers at least 150 minutes in the exposed and non exposed group before COHb concentration measure in order to exclude smoking effects

The purpose of this study is to find out the level of understanding for pre-service physical-education teachers about the Paralympics and the differences between physical education majors and adapted physical education majors. For the purpose of the survey, a distinct difference between the groups on a survey has been identified. The survey material used for this study with a modification is based on Yeon-Sook Ko, Kyung-Sook Kim``s modified survey(2005) that scale analysis of disability attitude factor, which DFS(Disability Factor Scale) invented by Siller(1983) and translated by Jong-Nam Lee(1994), was used as a reference. For this study, collected 380 papers of information was updated and SPSS 18.0 program was used for its analysis with significant level of 5 percent or below. The frequency analysis has been conducted to figure out the subject``s general features, and t-test which is mean difference analysis and One-Way ANOVA have been conducted to see the awareness of the Paralympics. These tests were also used to verify differences between the two groups differentiated by major. The result are as followed. First, male have better understanding toward Paralympics than female do. However, none of statistical significance-difference was found. Second, the level of understanding toward Paralympics for all graders shows no sign of statistical significance-difference. Third, overall, adapted physical education majors have decent level of understanding toward Paralympics and the gap created from the fact, that whether he/she took adapted physical education classes, was shown. Fourth, a group with experience of volunteering turned out to have high level of understanding toward Paralympics and statistical significance-difference was found. It is shown that the differences about understanding toward Paralympics between the groups exist and pre-service physical-education teachers have lower level of understanding toward Paralympics compared to adapted physical-education majors. Fifth, the understanding level of pre-service physical-education teachers indicates areal gap and classes taken. In this study, a survey has been developed to find out the understanding level of Paralympics, which is one of the major events, for pre-service physical-education teachers and the differences between the groups have been identified. In this study which is to develop a survey as base line data to vitalize , it is suggested as followed. First, due to the fact that pre-service physical-education teachers were the subject for this study, an additionalstudy for a group of teachers who are currently working in the field should be made. Second, this study is only for major events of disabled for Paralympics. Later on, hence, study including morefeatures is a mandatory, such as various games, domestic sports festival for the people with handicapped. Third, due to this study is focused on pre-service physical education teacher, later, research which is forspecial education teacher should be needed for their better physical education service.

Background : For unresectable malignant hepatic tumors, cryotherapy is a good therapeutic alternative. The cryoprobe freezes hepatic tissue below -40℃. We wanted to evaluate how much this procedure affect to patient's temperature, because hypothermia complicate postanesthetic care. Methods : We reviewed medical records of patients who took cryotherapy only or combined with liver resection for hepatic malignancy for last 2 years. We adopted (No. of freezing-thawing cycle)×(No. of cryoprobes applicated) for indicator of freezing potency. Duration of recovery room staying and nasopharyngeal temperature before and after cryotherpy were reviewed. Results : Seven patients were included. The temperature decline ranged 0 to 0.4℃ and recovery time 20 to 35 min except 1 patient who stayed recovery room for 90 min. No relationship appeared between freezing potency and temperature decline or recovery time. Conclusion : Cryotherapy itself doesn't seem to lower body temperature significantly.

Background : Peripheral nerve injury can cause neuropathic pain states in which patients report painful sensation to stimuli that are normally innocuous (allodynia), or enhanced pain mechanism underlying neuropathic pain states are poorly understood. Since spinal glutamate receptor activation is a critical step in central sensitization, leading to spinal hyperexcitability in pain processing. Methods : Letf L5/6 spinal nerves were tightly ligated (SNL) to induce neuropathic pain in Harlan Sprague Dawley rats as described by Kim et al (1992). Two weeks after SNL, memantine 2 mg/kg directly injected into L5/6 spinal region in 10 μl followed by 10 μl saline. Hind paw withdrawal thresholds (PWT) to von Frey filament stimulation were tested for mechanical hypersensitivity in SNL rats injected intrathecally with memantine, before and post intrathecal injections in a blinded manner as detailed in Chaplan et al (1994). Results : Intrathecal injection of N-methyl-D-aspartate (NMDA) receptor antagonist memantine significantly reversed the allodynia state in SNL rats. Conclusion : The evidence provided by the study shows a strong correlation between inhibition of NMDA receptors and tactile allodynia. Increased NMDA activation can lead to a tactile allodynia under innocuous stimuli. Memantine can block the facilitated state of NMDA receptors and tactile allodynia in the SNL rats.

This study was performed to evaluate the ability of air-lifting and air-pulsing system which was applied a wastewater treatment facilities to retrofit the system. The factors of operating the system are hydraulic retention time, MLSS concentration and direct rejection time respectively. The experiments and results are as follows ; 1) It was the rejection time which enhanced the phosphorus removal efficiency in this system to reduce the secondary P-release to deteriorate the treated water. It was shown that the T-P removal was over 90% in HRT of 8 hours but the variation of air-lifting time from 30 minutes to 60 minutes were not fluctuated the removal efficiency of T-P. It means that the efficiency is no subject to air-lifting time. 2) The direct rejection process using the air-pulsing system was effective to protect the fouling in membrane and the concentration of effluent SS was stabilized during the operating period.
