Concentration and identification of airborne bacteria in the regulated public facilities were examined with the six-stage cascade impactor. Geometric mean total and respirable concentrations of airborne bacteria were $404cfu/m^3$ and $194cfu/m^3$ in hospital, $931cfu/m^3$ and $358cfu/m^3$ in kindergarten, $294cfu/m^3$ and $134cfu/m^3$ in day-care center, and $586cfu/m^3$ and $254cfu/m^3$ in postpartum nurse center, respectively. As a result, culturable total and respirable concentrations of airborne bacteria were significantly highest in kindergarten and lowest in day-care center (p<0.05). The ratio of respirable to total concentration of airborne bacteria in the investigated public facilities was ranged from 30% to 40% but there was no significant difference among them (p>0.05). The mean I/O ratio of culturable total and respirable concentrations were 0.58 and 0.66 in hospital, 0.71 and 0.83 in kindergarten, 0.28 and 0.41 in day-care center, and 0.63 and 0.78 in postpartum nurse center, respectively. Day-care center showed the lowest I/O ratio of culturable total and respirable concentration of airborne bacteria (p<0.05) but a significant difference was not found among other facilities. Indoor concentration of airborne bacteria did not correlated significantly with indoor temperature and relative humidity (p>0.05) but had a significant positive correlation with $CO_2$ and surrounding condition (p<0.05). Staphylococcus spp., Micrococcus spp., Corynebacterium spp., and Bacillus spp. were dominant genera and amounted to over 95% of total airborne bacteria identified in the investigated public facilities. Size distributions of four dominant genera did not observed inconsistently regardless of type of public facility.

The purpose of this study was to review the government's policy on the enhancement of sports facilities for community residents regarding the lack of knowledge surrounding the infrastructure of sports facilities. The government has invested approximately 2.4 trillion won to establish 220 community sports centers, 385 billion won for 194 multi-purpose indoor centers, and 1.3 trillion won for rebuilding 1,870 school outdoor fields. On the other hand, there are problems with the link between the crumb rubber infill on sports fields and cancer, a lack of availability of indoor sports centers, and an increased federal budget deficit. It is the responsibility of government to plan and construct outdoor fields that are large enough to accommodate all people and allow them to play activities. In addition, the guidelines should ensure that the indoor space required for physical activities at each teaching station is large enough to accommodate all students in the class and handle two classes. The government should suggest the federal government guidelines based on a good understanding of the concept of infrastructure in sports facilities. The government also should make efforts to reduce the regulatory powers and provide the community with an autonomous right to plan and construct sports facilities.

The daily life activities of primary school children have been increasingly diversified. This research examined the spatio-temporal characteristics of primary school children's daily life activities. The time allocation of primary school children's daily activities was monotonous. They tended to spend most of their time in school activities, private lessons after school, and studying at home. The daily trip to school has been diversified as the result the of increase in the number of double-income families, car owners, facilities for pastime, and educational facilities for private lessons after school. The selection of educational facilities for private lessons was strongly influenced by accessibility to the residence because of the limited time budget of primary school children and the controlled trip behavior by parents. The leisure activities were considered as a minor function and took place in the interval of performances of study-related activities. The high proportion of leisure activities was found in the indoor play. The amount of the time for leisure activity was very insufficient. The spatial range and time budget were strongly influenced by the institutional conditions of parents.

Due to the lack of available site in urban setting outdoor space in elementary schools are getting smaller and tend to be replaced by indoor spaces. Focusing on courtyard, piloti space and roof space, this study analyzed the current condition and usage of the outdoor spaces in the urban mini-schools based on the analysis of architectural drawing, interview, survey, and observation. Following issues are found for appropriate planning for outdoor spaces in the urban mini-schools. Firstly, roof space needs to be coordinated with the physical education and outdoor class curriculum and should be planned separately for quiet activities. Secondly, the piloti space should be planned as an independent space rather than a connection between classroom and outdoor space, with appropriate surveillance from teacher's space for the lower graders. Thirdly, courtyard space, typical space in urban mini school surrounded by densely arranged buildings, should be thermally controlled for outdoor class or resting with appropriate screen from noise to keep quiet atmosphere.

The purpose of this study is to examine the improvement of the slipperiness of building floors and to test the safety in accidental collision in the primary schools. To perform this purpose effectively, the actual 20,202 cases of accident on the year 2000-2009 which had been dealt by Seoul School Safety and Insurance Association were analysed in several aspects. And to test the current slipperiness and hardness of building floors, 3 primary schools whose construction year differed were examined. This study found that among the indoor accidents of 2,646 cases on the year 2000-2002, 70.7% accidents of them were caused by slipperiness. It was also found that the building floors of the primary schools could not be safe from the result of examining the slipperiness and hardness of the building floors. As the result of this study, it showed that the desirable efficient criterion of slipperiness would be more than C.S.R 0.4, and that of safety in accidental collision would be less than Gs 100G for the safety of primary school students.

Recently, indoor air quality (IAQ) in workplace, residential environments and schools has been concerned of people, scientists and related the public, and has recognized the healthy effectsrelated to IAQ, specially in schools in Korea. Therefore, objectives of this study in this study were to measure and compare the perception of TAQ of selected air pollutants in Seoul from April to September 2004. Measurement place measured 2 schools of Seoul and local 9 schools (by Kyonggi Province, Chungchong-bukdo Chungchong-namdo, Chollado-bukdo, Cholla-namdo, Kyongsang-bukdo, Kyongsang-namdo, Kwangju, schoolin Pusan each 1 place). Temperature, humidity, illumination, carbon monoxide, carbon dioxide, TBC (total bacteria count), noise, PM10, TVOC(total volatile organic compounds), HCHO (formaldehyde) were measured simultaneously. Also, we Performed a questionnaire survey of 250 students and 50 teachers about their awareness for the importance of IAQ in their schools. Among this article, we handled noise, carbon monoxide, carbon dioxide, TBC, TVOC, HCHO, PM 10 in our conclusion. Major results were as follows ; Carbon monoxide (CO) was lower than indoor air standard of Korea. Carbon dioxide $(CO_2)$ appeared that 4 schools among our sample target school exceeded in normal standard. 4 schools were almost similar with normal standard. TBC appeared that 7 schools among 11 schools were higher than standard. Noise measured school's mean value passed exceeded standard. And school which passed over standard appeared to 7 schools among 11 schools. HCHO was exceeded 4 schools by standard that excess and certainly interrelation between school's establishment year and facilities of construction was detected. PM10 was exposed all schools by fitness in standard. TVOC appeared that 9 schools among 11 measurement school was exceeded health effect standard of Japan.

This study was conducted to measure the concentrations of total culturable bacteria (TCB) and to identify the bacteria in thirty public facilities (7 elderly-care facilities, 4 hypermarkets, 4 university hospitals, 7 child care facilities, 4 subway stations and 4 bus terminals) in Seoul and Gyeonggi-Do Province. Although all concentrations measured in these study facilities did not exceed the national maintenance standard, it is believed that elderly-, child-care facilities should be high priority facilities to improve the indoor air quality and it is important to study the health effects and the airborne bacteria concentration of public facilities including non-culturable bacteria or allergen.
Objectives: In Indonesia, 61 million adults smoked in 2018, and 59 million were exposed to secondhand smoke at offices or restaurants in 2011. The Presidential Decree 109/2012 encouraged local governments to implement a smoke-free policy (SFP), and the city of Jayapura enacted a local bill (1/2015) to that effect in 2015. This study aimed to evaluate compliance with this bill and to explore challenges in implementing it. Methods: We conducted a mixed-methods study. Quantitatively, we assessed compliance of facilities with 6 criteria (per the bill): the presence of signage, the lack of smoking activity, the lack of sale of tobacco, the lack of tobacco advertisements, the lack of cigarette smoke, and the lack of ashtrays. We surveyed 192 facilities, including health facilities, educational facilities, places of worship, government offices, and indoor and outdoor public facilities. Qualitatively, we explored challenges in implementation by interviewing 19 informants (government officers, students, and community members). Results: The rate of compliance with all 6 criteria was 17% overall, ranging from 0% at outdoor public facilities to 50% at health facilities. Spatial patterning was absent, as shown by similar compliance rates for SFP facilities within a 1-km boundary around the provincial and city health offices compared to those outside the boundary. Implementation challenges included (1) a limited budget for enforcement, (2) a lack of support from local non-governmental organizations and universities, (3) a lack of public awareness at the facilities themselves, and (4) a lack of examples set by local leaders. Conclusions: Overall compliance was low in Jayapura due to many challenges. This information provides lessons regarding tobacco control policy in underdeveloped areas far from the central government.

Objectives: The purpose of this study was to assess the indoor levels of $PM_{10}$, VOCs and aldehydes in nail shop and hair salon. Methods: The field survey was conducted for 52 hair salons 52 nail shops, and 26 shop-in-shops in Seoul and Daegu city. The field technicians investigated characteristics of each shop including operating time, indoor volume, ventilation and so on. Indoor concentrations of $PM_{10}$, VOCs and aldehydes, indoor temperature and humidity were measured in 12 hair salons, 12 nail shops and 6 shop-in shops. MP Surveryor II (Graywolf, USA) was used to measure $CO_2$ concentration, temperature and humidity for 8 hours. $PM_{10}$ concentrations were measured by minivolume air sampler with Teflon quartz filter ($0.2{\mu}m$ pore size, ${\varphi}$ 47 mm, Graseby-Anderson TEF-DISKTM) for 6 hours. VOCs passive sampler (OVM 3500) was used to collect VOCs for 8 hours and analyzed by GC/MSD. Results: The $CO_2$ concentrations were $759.4{\pm}58.2$ ppm in nail shops, $731.0{\pm}72.5$ ppm in hair salons, and $656.4{\pm}31.2$ ppm in shop-in-shops. The $PM_{10}$ concentrations were $27.5{\pm}14.2{\mu}g/m^3$ in nail shops, $33.1{\pm}6.3{\mu}g/m^3$ in hair salons, and $39.0{\pm}26.9{\mu}g/m^3$ in shop-in-shops. TVOCs concentrations were $3085.4{\pm}1667.8{\mu}g/m^3$ in nail shops, $2131.1{\pm}617.3{\mu}g/m^3$ in hair salons, and $1550.3{\pm}529.0{\mu}g/m^3$ in shop-in-shops. TVOCs concentrations in nail shops were significantly higher than those in hair salons and shop-in-shops (p=0.002). Formaldehyde concentrations were $60.8{\pm}36.6{\mu}g/m^3$ in nail shops, $89.1{\pm}55.4{\mu}g/m^3$ in hair salons, and $45.1{\pm}22.5{\mu}g/m^3$ in shop-in-shops. Conclusion: TVOCs concentrations in nail shop were the highest among others. TVOC concentrations in all stores exceeded indoor air quality stand of indoor air quality control in public-use facilities, etc act.

The purpose of this paper is to study and propose playground facilities for physically challenged children to cultivate adaptability in society and advances the opportunity of participate in physical exercise. This study carried out site investigations by visiting and inspecting various facilities: a recreational walking path for physically challenged people, a care facility for physically challenged children, a special school for physically challenged children, and "Madel Park", a private-use playground for physically challenged children. The result of the site investigation found that, overall, play facilities are difficult to use for physically challenged children. In addition, because park space is often small and narrow, children who are restricted to wheelchairs find it impossible to access such facilities. By carefully inspecting each of the facilities, the author found suitable elements to apply for outside play space. These elements include the introduction of an essential slope way to allow for safe movement, the provision of special seats which support the body to outside play equipment and the adaptation of treatment room instruments that assist balance to outdoor playground facilities. On the basis of the site investigation the interview and the indoor education program for physically challenged children the author completed an outside play program. Each item in this program was classified as belonging to either a "sense play" program or and "exercise play" program. Finally, the author designed suitable play equipment for physically challenged children corresponding to each item in the exercise programs in order to research the appropriateness of the equipment to its intended use. This research is the first step. From this point the author expects that specific applications will be developed through a practical space plan and sufficient clinical experiments involving use of the new equipment.
