Objectives: The purposes of this study were to investigate the installation rates and status of indoor smoking rooms in public facilities and to determine the level of compliance level with smoke-free policies in accordance with the National Health Promotion Act. Methods: A visiting survey was conducted on 1,206 public facilities in the Seoul Metropolitan Area and the Daegu and Gyeongsangbuk-do Province area. Researchers selected public facilities such as bars, coffee houses, and internet cafes using convenient sampling. They visited without prior notice, checked the existence of indoor smoking rooms, and recorded their status. Results: Internet cafes (110/116) had the highest installation rate of indoor smoking rooms, followed by bowling clubs (17/19) and billiard rooms (87/100). Depending on the type of business, 50-88% of smoking rooms were not completely enclosed. Coin karaoke rooms showed the least inadequacy in this regard. In addition, out of 512 smoking rooms, in 33% (n = 169) smoking indoors was observed in non-smoking areas. Only 9% of public facilities were in full compliance with the indoor smoke-free regulation. Conclusions: It was found that most of the public facilities with indoor smoking rooms did not comply with the smoke-free policy, and smoking was still observed inside some facilities. Therefore, there is a need for a policy that prohibits indoor smoking rooms completely.

Purpose: This study aimed to identify regional differences in problem drinking among adult males in single-person households and predict the determinants. Methods: This study used data from the 2019 Community Health Survey. Geographically weighted regression analysis was performed on 8,625 adult males in single-person households who had been consuming alcohol for the past year. The Si-Gun-Gu was selected as the spatial unit. Results: The top 10 regions for problem drinking among adult males in single-person households were located in the Jeju-do and Jeollanam-do areas near the southern coast, whereas the bottom 10 regions were located in the Incheon and northern Gyeonggi-do areas. Smoking, economic activity, and educational level were common factors affecting problem drinking among this population. Among the determinants of regional disparities in problem drinking among adult males in single-person households, personal factors included age, smoking, depression level, economic activity, educational level, and leisure activity, while regional factors included population and karaoke venue ratio. Conclusion: Problem drinking among adult males in single-person households varies by region, and the variables affecting each particular area differ. Therefore, it is necessary to develop interventions tailored to individuals and regions that reflect the characteristics of each region by prioritizing smoking, economic activity, and educational level as the common factors.

This study suggests criteria to conduct a risk assessment of VOCs and formaldehyde in uncontrolled public facilities. Pollutants and facilities were selected based on two years of monitoring data and exposure scenarios in 573 uncontrolled public facilities, composed of 10 types of public institutions. With the exception of social welfare facilities, lifetime ECRs of formaldehyde and benzene in each facility were higher in employees than in users, except in social welfare facilities. In social welfare facilities, the risk of benzene for users ($1{\times}10^{-5}$) was higher than that of workers ($1{\times}10^{-6}$) because facility users live in the facility 24 hours per day, compared to workers who spend an average of 8 hours per day in the facility. The risk of benzene to workers in restaurants, academies, performance halls, internet cafe and pubs were estimated as high as $1{\times}10^{-4}$ and the risk to workers in the theaters and karaoke bars were recorded as $1{\times}10^{-5}$. Because lifetime ECRs of carcinogens exceeded $1{\times}10^{-4}$ for workers and users in most facilities, risk management of formaldehyde and benzene in these facilities is necessary. Although HQs of toluene and xylenes did not exceed 1.0, their HQs did exceed 0.1 in some facilities, so they were evaluated as potentially harmful materials. Additionally, criteria for health protection in IAQ by facility are suggested at $60-100\;{\mu}g/m^3$ for formaldehyde, $400-500\;{\mu}g/m^3$ for TVOCs, $10-20\;{\mu}g/m^3$ for benzene, $150-170\;{\mu}g/m^3$ for toluene and $100\;{\mu}g/m^3$ for xylenes, based on the survey on IAQ and HRA methodology. The excess rates of IAQ to health protection criteria in all facilities were 16% for formaldehyde, 8% for TVOCs and benzene, 9% for toulene, and 5% for xylenes.

점화원이 무엇이든 화염의 확산과 인체에 영향을 미치는 직접적인 요소는 가연물이다. 음악학원, 노래방 등에서 사용하고 있는 마감재인 흡음재는 폴리우레탄으로 구성되며 연소 시 다량의 유독가스를 발생한다는 것은 알려진 사실이다. 그럼에도 현행법은 학원의 경우 수용인원 100명 미만의 경우 난연 마감재를 사용해야 한다는 강행규정이 없다. 본 연구에서는 실제 음악학원에 설치된 흡음재를 수거하여 실화재 연소실험을 통해 화염확산 속도를 측정하였으며, MultiRaelite 복합가스 측정기(타겟물질 VOC, HCHO, SO₂, CO₂, CO, HCN, NO₂)를 이용하여 유독가스를 측정한 결과 Time weighted average (TWA)와 Short term exposure limit (STEL)의 허용농도를 초과하여 기기한계값이 측정되었다. 또한 시중에 판매중인 난연 흡음재와 비난연 흡음재를 비교 연소 실험한 결과, 착화 및 확산에 있어 현격한 차이를 보였다. 따라서 실험결과를 바탕으로 수용인원 100명 미만의 학원에도 난연 마감재 사용을 강제할 필요가 있음을 제언하고자 한다.

Background: Airborne fungi are ubiquitous in the air and exposure to an airborne fungus can be a significant risk factor. The composition of fungi has been potentially important for human health, especially for respiratory diseases like asthma and atopic dermatitis. Therefore, we attempted to ascertain what kind of airborne fungi affect human health at a nationwide level. Objectives: This study was carried out to provide information on indoor fungi distribution at multi-use facilities throughout South Korea. Methods: We classified our data by region and public facility after collection, cultivation, and identification via the sequencing of the ITS (internal transcribed spacer) region. We investigated whether or not the proliferation of HaCaT cells was affected by the identified airborne fungi. Results: In our data, the most isolated airborne fungi by region were Penicillium spp (Seoul, Daegu), Periconia sp (Gyeonggi-do), Iprex sp (Gangwon-do), Phanerochaete sp (Busan), Bjerkandera sp (Gwangju), and Aspergillus sp (Jeju-do). In the public facilities, the most detected fungi were Cladosporium sp (public transport), Penicillium sp (apartment house, retail market, financial institution, karaoke room), Bjerokandera sp (underground parking lot, public toilet, medical institution), Periconia sp (retail store), and Fusarium sp (general restaurant). Next, we selected twenty airborne fungi to examine their cytotoxicity and proliferation of human skin cells. In this experiment, the proliferation of the cells was influenced by most of the identified fungi. In case of the cytotoxicity test, most genera except for Rhodotorula sp and Moesziomyces sp showed cytotoxicity in HaCaT cells. Conclusions: The distribution of mold in the indoor air in multi-use facilities in South Korea differs from region to region, and this is an indicator that should be considered in future health impact studies. In addition, as a result of culturing about 20 types of bacteria dominant in indoor air, it was found that most (90%) inhibit the growth of skin cells, which can be harmful to health. An in-depth study of the health effects of floating fungi is needed.
