To reduce subway passengers’ exposure to PM10 (particulate matter less than 10 micrometers), management ofPM10 concentration in underground stations is critical. In this study, we attempted to investigate the distributionof airflow PM10 concentration in an underground station. The numerical simulations were performed usingcomputational fluid dynamics. In order to apply to CFD, measurement of air volume (supplied and exhausted air)and PM10 concentration were conducted at the concourse and platform areas of the underground station. The resultsof the simulation agreed with the actual PM10 concentration, and we confirmed the distribution of PM10concentration depending on air volume conditions. This result will be helpful to reduce the PM10 in an undergroundstation when using ventilation system.

The cost of game testing in the video game industry is significant, accounting for nearly half of the expenses. Research efforts are underway to automate testing processes to reduce testing costs. However, existing research on test automation often involves manual tasks such as script writing, which is costly and labor-intensive. Additionally, implementations using virtual environments like VGDL and GVG-AI pose challenges when applied to real game testing. In this paper, we propose a tool for automating game testing with the aim of system fault detection, focusing on a Unity platformer game. The proposed tool is based on a commercial game engine, autonomously analyzing the game without human intervention to establish an automated game testing environment. We compare and analyze the error detection results of the proposed tool with a random baseline model using open-source games, demonstrating the tool's effectiveness in performing automated game analysis and testing environment setup, ultimately reducing testing costs and improving quality and stability.

The northern region of Chungcheongnam-do is located in several large-scale industrial facilities. The region of Daesan has a large-scale petrochemical complex, accounting for 7.3% of the nation’s total VOCs(volatile organic compounds, VOCs) emission. In this study, VOCs were measured at 31 locations in the Daesan area using a passive sampler; VOCs concentration distribution by area and the influence of the different seasons on the VOCs in the area were investigated. The result of seasonal measurement of VOCs, the highest concentration was measured in winter (18.6 ppb), summer (12.0 ppb), and spring and autumn (10.5 ppb). Benzene and toluene accounted for 69.1 to 72.7% of the VOCs concentration regardless of the season. The result of investigating the affected area based on the benzene measurement, high concentrations of VOCs were identified in a specific area. Although the distance from the pollutant source is important, it was confirmed that the diffusion depends on the wind direction, wind speed and topography. In order to improve the problems of highconcentration VOC areas, continuous monitoring and national policies will be required.

Although today most injuries of face and head are the result of traffic accident, dog bites are a cause of facial injuries in children. In recent years, general guidelines have been established concerning the surgical treatment of facial dog bite injuries in children. Contrary to past beliefs, primary closure of selected bites produces the best outcome for patients without increasing the risk of infection. Special attention is attached to the functional and aesthetic outcome. The purpose of this article is to provide the oral and maxillofacial surgeon about management of facial dog bite injuries and guidelines for effective and rational treatment with review of a literature. We report a case of multiple facial dog bite injuries treated surgically by primary closure of the wound and secondary revision with rotation flap after excision of partial necrotic tissue. 아동에서 개에 의한 안면부 교상의 치료시 과거에는 감염의 위험 때문에 일차봉합술을 시행하지 않았으나 오늘날에는 일차봉합술을 추천하고 있다. 안면부 교상의 이차 치유시에는 바람직하지 않은 반흔이 발생하므로, 많은 악안면성형외과의사들은 최선의 기능적 및 심미적 결과를 얻기 위해 감염이 적은 교상에서는 12시간 내에 일차봉합술을, 그리고 심한 안면부 교상이나 조직 결손시에는 피부이식이나 유경피판을 이용한 일차재건술을 추천하고 있다. 본 증례에서는 개에 의한 안면부 다발성 교상을 주소로 응급실을 통해 본과에 내원한 3세 남아에서 파상풍 예방접종과 예방적 항생제 투여 및 일차봉합슬을 시행하였고, 부분적 괴사조직의 절제 및 국소 회전피판을 이용한 이차 수정술을 시행하여 양호한 결과를 얻었기에 문헌 고찰과 함께 보고하는 바이다.
