Purpose: This study sought to explore current status of children's swimming pool in Korea and to generate insights regarding safety management of children's swimming pool. Research design, data, and methodology: The study reviewed literatures including documents of Ministry of Culture, Sports and Tourism and sport facility-related articles. Furthermore, the study collected additional statistics via search engines. Results: First, numbers of swimming pools have been dramatically increased since 2016 and Korea experienced an increase of 37% from 2010 to 2019. Of the 611 indoor swimming pools, most swimming pools are located in Gyeonggi province with 27.7% (n=169). Seoul and Gyeonggi-do have the highest proportion of swimming pools in Korea. Second, in types of swimming pools, 47.6%(n=291) was children's swimming pool which is the highest proportion in the nation. Children's swimming pools are also mostly located in Seoul and Gyeonggi province with 57%. Third, of 372 profit swimming pools, children's pools show the highest number with 78%(n=291). Conclusions: Children's swimming pools are picking up faster than the other types of swimming pool. Yet, safety-related studies are still lack. This provides motivations to produce managerial insights from academia and business sectors. Moreover, more studies of legal issues should be conducted. Implications were discussed.

This study is empirically intended to look into the effects of HVAC management on condensation cause and prevention in indoor swimming pools. The findings are summarized as follows. First, the experience of condensation in indoor swimming pools showed that 132 out of 142 people in total experienced the condensation in indoor swimming pools, which they had a high experience rate of 92.3%. For the location of condensation, the wall joints were 46.8% and the windows were 34.5%, which a total of 72.3% occurred in the wall joints and windows. Second, the effect of construction design, HVAC management and building construction on the cause of condensation in indoor swimming pools showed that building construction had an effect on the cause and location of condensation depending on the seasonal time, partially adopting hypothesis 1. Third, the effect of condensation-causing factors on condensation-preventing factors in indoor swimming pools showed that condensation had a close relationship with air and temperature conditions depending on the time and location of condensation, adopting hypothesis 2. As for the above-stated findings, the HVAC management in indoor swimming pools is an important concern factor that continues to cause condensation despite the development of advanced construction materials. Especially, building construction is a main factor that has a direct effect on condensation in the HVAC management of facilities. This implies that the window management is important in maintaining the wall joints - which can suppress the selective use and defect occurrence of construction materials - or confined spaces for a long time.

Objectives: This study was conducted to investigate skin and eye symptoms according to swimming pool user characteristics and chlorine concentration at indoor swimming pools in the Daegu region. Methods: A total of 296 swimming pool users were enrolled from the eight swimming pools randomly chosen in Daegu. Each user completed a self-administered questionnaire with general, swimming related, and symptoms suffered throughout December 2008 to August 2009. The water analysis of swimming pools was substituted with the swimming pool water analysis practiced by district offices to 2008. Results: There were significant differences in experience rate of self-reported skin and eye symptoms between coaches and students except dander. The users of swimming pools having higher chlorine concentrations suffered from more frequent skin and eye symptoms. The results of multiple logistic regression analysis for experience of skin symptoms showed that coaches (OR = 6.81, 95% CI: 2.46~18.81) and pools with chlorine concentrations over 0.4 mg/l (OR = 1.75, 95% CI: 1.01~3.03) were the significant variables. For experience of eye symptoms, coaches (OR = 4.13, 95% CI: 1.25~13.69) at a swimming pool was the significant variable. Conclusions: Increased exposure to swimming pool water and exposure to swimming pool showed that higher chlorine concentration may cause more frequent skin and eye symptoms.

Social network service (SNS) data related to green tourism were used to estimate preferred tour sites and users' interests. Keywords related with green tour activities were employed to search the SNS data. SNS data were collected from Korean blogs such as Naver and Daum from June $1^{st}$ to August $31^{st}$ between 2015 and 2017 using text-mining solution. During the study period, seven hundred and five posts were analyzed. Associated words that frequently co-occurred with keywords were classified into different categories depending on the nature of associated words. Associated words included swimming pools and camping sites (location); experience and swimming pools (attribute); and water play and culture (culture/leisure). Our data suggest that SNS users with experience of green tourism in Korea exhibited interest in green tourism with swimming pools, camping sites, experience, water play and/or culture rather than particular popular sites. Based on the findings, it is recommended that preferred facilities such as swimming pools should be provided at green tourism sites to meet the users' needs and to facilitate green tourism.

A total of 60 samples were collected from 35 swimming pools in Beijing, China, and the presence of Cryptosporidium and Giardia were investigated. The results showed that 16.7% and 15.0% of samples were positive for Cryptosporidium oocyst and Giardia cysts, respectively, with a mean concentration of 0.30 oocysts/10 L and 0.27 cysts/10 L. The oocysts and cysts were found to have higher rates of occurrence in August than in May. Genotyping confirmed the presence of Cryptosporidium hominis, C. parvum, and Giardia assemblages A and B, all of which were associated with human infections. The predominant species/assemblages were C. hominis and Giardia assemblage A. Analyses of the relationships between parasite oocysts/cysts, indicator bacteria, and physical-chemical parameters revealed that there was no correlation between 2 parasites and fecal bacterial indicators, whilst there was a significant correlation between protozoa and urea concentration, which indicates that urea concentration rather than fecal bacterial indicators might be an appropriate index for chlorine-resistant protozoa in swimming pools. This study provides useful information to improve the safety of swimming pool water and deduce the risk of protozoan infections.

Recently, in accordance with the interesting on well-being as well as the revitalization of living athletics, it is current tendency that people who use the swimming pools are on increasing. However, because the most of indoor swimming pools have ever used the reflection finishing materials likely as the tile due to the property of its hydrophilic space, the inside of indoor swimming pool is vibrating too much, and some problem which the voice and music do not delivering clearly is occurring when swimming lessons or underwater aerobics(synchronized swimming) and swimming game. Based on such viewpoint, locating the object on actually built indoor swimming pool, this Study has ever grasped its physical acoustic property, and finally designed the indoor swimming pool that contains an optimum acoustic condition, by remodelling it through an acoustic simulation. It is considered that such study result could be utilized as the useful materials when constructing the similar indoor swimming pool, hereafter.
