본 연구는 유독가스 누출사고 발생 시의 피난행동 분석을 위한 기초적 연구로서, 피난행동에 영향을 미치는 요인의 탐색과 피난 시 이동방법 및 정보전달수단의 파악, 더불어 배경요인에 따른 유의차 분석에 그 목적이 있다. 이를 위해 한국(n=158)과 일본(n=108)의 청년층을 대상으로 설문조사를 실시하였으며, 탐색적 요인분석(EFA)과 모평균 차 검정(t-test)을 이용하여 분석을 실시하였다. EFA의 결과, 한국과 일본 모두 추출된 요인구조는 유사한 것을 확인할 수 있었다. 한국인의 경우, 약 74%가 ‘자동차&오토바이’를 피난 시 이동수단으로서 선택하였으며, 정보전달 방법으로 약 36%가 ‘SNS&인터넷’을 선택했다. 한국 청년층은 일본에 비해 유의하게 유독가스 및 화학공장에 대한 공포감과 지식이 높았으며, 피난에 대한 불안감은 유의하게 낮은 것을 알 수 있었다. 성별에 따른 유의차는 불안 및 지식에서 확인할 수 있었다. The purposes of this study are to investigate the factors influencing evacuation behavior, means of transportation, effective information tools, and country and gender effects in cases of toxic gas release. In this study, questionnaire surveys were conducted among Korean (n=158) and Japanese (n=108) younger adults. Explanatory factor analyses revealed that the extracted factor structures for the Korean and Japanese samples were similar. Surveys indicated that approximately three-quarters of Koreans (74%) chose “vehicle and motorcycle” as means of transportation, and 36% chose “Social network service and Internet” as effective information tools. Korean younger adults significantly rated knowledge and fear regarding toxic gas and chemical plants and lower anxiety about evacuation higher than Japanese younger adults. Gender effects were also identified regarding knowledge and anxiety.

최근 다양한 가스 누출 사고가 발생하고 있으며, 유독가스가 대량으로 누출되는 경우 인근 주민은 피난해야할 필요가 있다. 이에 본 연구에서는 유독가스 누출 시의 피난의지 및 효율적인 사고 정보전달 방법에 대하여 분석하고자 하였으며, 이를 위하여 대학생(n=225)을 대상으로 설문조사를 실시하였다. 그 결과, 유독가스 누출 시 피난에 관련된 정보에는 피난장소를 포함하고 공적기관으로부터 옥외스피커를 이용하여 전달하는 것이 효율적일 것으로 판단된다. 또한, 평소에 화학공장으로부터 얻고 싶은 정보로는 안전정보보다 재해정보 및 피난장소에 대한 정보를 더 원하는 것으로 나타났다. 더불어 화학공장에 대한 공포감과 화학적 지식, 성별에서 유의차를 확인할 수 없었으나, 피난의지와는 유의한 관계가 있는 것을 확인하였다. In case of toxic gas release from a chemical plant, local residents may need to evacuate. The purpose of this survey for college students (n=225) is to investigate willingness to evacuate, and to find effective ways delivering emergency information when toxic gas release happens. According to survey, in the emergency situation, it is effective to use outdoor speakers by authorities to provide information regarding accidents and evacuation area. Also, in non-emergency, respondents show the tendency preferring to obtain information about accidents and evacuation area from the chemical plant rather than safety record. Futhermore, survey shows that fear for chemical plant is not affected by gender and scientific knowledge, while a statistically significant difference was found between fear for chemical plant and willingness to evacuate.

The purposes of this study were to investigate characteristic changes on nonwoven fabric by the charcoal printing. It separate grind charcoal as two different size of particles 45-52㎛ and 53-65㎛ for hand screen printing on three kind of nonwoven fabrics. To examine the effect of charcoal printing on nonwoven fabric were to obwerve surface changes by a scanning electron microscope, dyeability by using spectrophotometer, moisture regain by oven method, air permeability, anion property, deodorization and antibacterial activity. The results were as follows: When charcoal powder concentration increased from 3 to 9%, K/S value also increased from 3.06to 8.55. When charcoal concentration increased, moisture regain also increased. In same concentration, moisture regain occurred higher as particle of small size. Air permeability decreased when the charcoal printing concentration increased. Anion occurrence appeared 140-160ion/㏄ from three different kinds of nonwoven fabrics in 3% and 9% charcoal concentration. Therefore, occurred anion ineffectively. In concentration of 3%, rate of deodorization measured as 89%, 83% and 87%, and 9% concentration caused 96%, 86% and 93% of high deodorization. Antibacterial activity examination in nonfinished nonwoven fabric resulted range of 60% however, 3% and 9% concentration finished nonwoven fabric resulted 99.9% of excellent antibacterial activity.

This study evaluates the comfort and suitability of safety clothing. We made three safety clothes ‘y’, ‘lg’, ‘lgH’. Only ‘y’ made with fluorescence fabric has passed International Standards (ISO 20471). A wearing test investigated the physiological response and subjective sensations at 30°C and 50% RH, six men participated. Mean skin temperature and tympanic temperature showed significant difference with experimental course (p< .05). The micro-temperature (Tm) showed significant differences between three garments on the thigh (p<.01). When wearing ‘lg’, Tm was the highest. Micro-humidity indicated the interaction between clothing and the experimental course on the chest with no significant difference; however, there was a low tendency when wearing ‘lgH’ after the second half of exercise. The sweat rate indicated a significant difference between ‘lg’ and ‘lgH’ at 20 minutes of exercise (p<.05). Three sensations showed significant differences with the time (p<.01), there was also a tendency to feel hotter and more humid when wearing ‘lg’. Skin sensation showed significant differences between pre-experiment and post-experiment (p<.05), ‘y’ was the most preferred. The ‘lg’ with long-sleeved currently worn in Korea tended to feel hotter, more humid and more uncomfortable than ‘y’. It indicates that there is room for improvement in Korean safety clothing.
