This study investigates the influence of particulate matter concentrations on the incidence of asthma, focusing on the delayed onset of symptoms and subsequent medical consultations. Analysis incorporates a four-day lag from the initiation of fine dust exposure and compares asthma patterns before and after the World Health Organization's (WHO) classification of fine dust as a Group 1 carcinogen in November 2013. Utilizing daily PM10 data and asthma-related medical visit counts in Seoul from 2008 to 2016, the study additionally incorporates Google search frequencies and newspaper article counts on fine dust to assess public awareness. Results reveal a surge in search frequencies and article publications after WHO announcement, indicating heightened public interest. To standardize the long-term asthma occurrence trend, the daily asthma patient numbers are ratio-adjusted based on annual averages. The analysis uncovers an increase in asthma medical visits 2 to 3 days after fine dust events. Additionally, greater public awareness of fine dust hazards correlates with a significant reduction in asthma occurrence after such events, even within 'normal' fine dust concentrations. Notably, behavioral changes, like limiting outdoor activities, contribute to this decrease. This study highlights the importance of analyzing accumulated medical data over an extended period to identify general public behavioral patterns, deviating from conventional survey methods in social sciences. Future research aims to extend data collection beyond 2016, exploring recent trends and considering the potential impact of decreased fine dust awareness amid the COVID-19 pandemic.

In the Republic From the national interest in the recent hiring scandals in the public institutions such as the Financial Supervisory Service, Gangwon Land, and so on, people were outraged by the fact that the competition opportunities were not secured although they should be equally secured to compete with anyone with their capabilities in the fair process. Hence, the government made the public institutions blind hiring to be mandatory, which eliminated writing the academic background, GPA, and English score in the application form and selected the new employees only with job competencies in the public institutions in 2017. In 2018, the prosecution did their best for the investigation on hiring scandal with the strong will to cut the scandal upon announcement of 5-year anti-corruption master plan. Amid this controversy, this study tries to suggest the further direction in the hiring military human resources upon introduction of blind hiring system, reviewing the needs to introduce blind hiring system in the military, the governmental guideline according to the mandatory blind hiring in the public institutions, and the application status of modified blind hiring in the military.

Current Android smartphones include about 25 to 35 essential applications(unerasable) related to function and operation of the android smartphone itself and about 30 optional applications(removable) provided by carriers, Google and manufacturers. These applications were not able to be removed until the announcement of the smartphone applications pre-install guide from the government in January 2014, so there were memory limitations in installing new applications, causing consumer complaints by consuming data during the auto-update process of the pre-installed applications. After the announcement, we were able to delete optional applications but the complaints about the data consumption still did not disappear. Therefore, in this paper, we carried out the customer survey and analyzed the behavior information such as how carriers are operating pre-installed applications and what kind of applications customer prefers and how many applications customer wants to be pre-installed. And we proposed how to configure pre-install applications on smartphone for customer needs.

The recent policy statement by the Cancer Council of Australia on infant circumcision and cancer prevention and the announcement that the quadrivalent human papillomavirus (HPV) vaccine will be made available for boys in Australia prompted us to provide an assessment of genital cancer prevention. While HPV vaccination of boys should help reduce anal cancer in homosexual men and cervical cancer in women, it will have little or no impact on penile or prostate cancer. Male circumcision can reduce cervical, penile and possibly prostate cancer. Promotion of both HPV vaccination and male circumcision will synergistically maximize genital cancer prevention.

This study investigated the contents of twitters of metropolitans by year and city using language network analysis. The possibility of twitter as a medium of information provision was also explored. This study employed KrKwic, Ucinet6, and Netdraw programs to conduct language network analysis. As the results, the network was mainly formed with information about civic administration (citizen, management, opening service, participation) and information about citizens living (cultural events, parks, way to work) in 2014. However, information about civic service and announcement (citizen, civic opinion, opening service, civic service, events) occupied a central role in the network of 2015. The results showed that different keywords were derived by year and city in network analysis by city.

The author Nakajima was involved in the field of disaster communications and emergency medical care as guest research scientist at the Fukushima Nuclear Accident Independent Investigation Commission established by the National Diet of Japan and reviewer of the Commission's report, and Kurokawa was the chairman of this Commission. Looking back over a decade, we are on the liability issue of bureaucrats and telecom operators, so it's becoming clear what was hidden at the time. The battery of NTT DoCoMo's mobile phone repeaters had a capacity of only about 24 hours, and communication failures increased after one day. The Government also failed to issue an announcement of "Vent from reactor" under the Telecommunications Act Article No. 129. This mistake lost the opportunity to use the third-party telecommunications (e.g. taxi radios). Furthermore, as a result of LASCOM (telecommunications satellite network for local governments via GEO) and a variety of unexpected communication failures, the evacuation order "Escape!" could not be notified to the general public well. As a result, the general public was exposed to unnecessary radiation exposure. Such bureaucratic slow action in emergencies is common in the response to the 2020 coronavirus.

Around the world, BIM application has been mandated. In Korea, an announcement was made in 2016 that BIM application will be required for all public constructions ordered by the Public Procurement Service. However, BIM cannot be used for building permits as Seumter, a building permit system, doesn't support BIM, even if it was used for building design. To utilize BIM for permit application, this study introduces a method of management for BIM-used permit application information. It was done by analyzing the data entered for new building permit application in Seumter. For the analysis, the permit application information is classified as internal BIM information and external BIM information and the required information is defined. To easily create and utilize the data types at the design stage, this study introduces a method of creating and utilizing a permit template. Also, this study developed a tool for combining the area information to add up all the related information such as gross floor area and floor area ratio. This study is significant in that it analyzes the required information for new building permit application among all the permit application types in Korea.

The purpose of this study is to investigate the effect of quality of management discussion and analysis (MD&A) disclosure on stock price crash risk. The MD&A can be seen to reflect the management's intention on public announcement and reveals directly what the management says to communicate with outside investors. A firm's high-quality MD&A implies the management's commitment to communicating with the market, not allowing the managers to have incentives to hoard unfavorable news, which if revealed to the public, may lead to downward stock price corrections, damaging corporate values. The high-quality MD&A is, thus, likely to reduce the stock price crash risk. We use a logistic regression to test whether MD&A influences crash risk using listed companies in the Korean Stock Exchange (KSE) stock market between 2010 and 2013. Findings of the empirical test show that the higher the quality of MD&A, the less likely crash risk appears, implying that the MD&A disclosed adequately can be one of the factors mitigating firm's stock price crash risk. This study has implications as it presents the MD&A disclosure as a factor influencing stock price crash risk and suggests voluntary disclosure as well as mandatory disclosure acts as a variable that explains the risk of stock price crash.
