기후변화 시나리오를 활용한 인천지역 강우에 의한 작업불능일 변화 연구
장준영,이찬식 한국건설관리학회 2018 한국건설관리학회 논문집 Vol.19 No.1
건설공사는 주로 옥외에서 이루어지기 때문에 토공사, 철근콘크리트 공사 등은 강우에 의한 작업불능일 수가 다수 발생한다. 특히, 지구 온난화에 의한 강우량 변화는 공기산정을 더욱 어렵게 하고 있다. 따라서 공정계획 수립 시 해당지역의 강우량 변화를 파악하고 작업불능일 수를 산정해야 한다. 이 연구에서는 인천지역의 1960년부터 2016년까지의 기상‘관측’자료와, 2018년부터 2074년까지의 기상‘예측’자료인 RCP 4.5를 활용하여 강우 변화시점을 파악하였고, 그 시점 전·후로 연 강우, 계절별 강우로 인한 작업불능일 수의 변화를 분석하였다. 그 결과 1972년, 1988년, 2013년, 2038년, 2050년, 2069년에 강우량이 뚜렷하게 변화한 것으로 나타났으며, 특히 2013년, 2038년, 2069년 기준으로 강우로 인한 작업불능일 수의 변화 폭이 큰 것으로 파악 되었다.

Off-Site Construction (OSC) is a new construction method based on factory production. OSC (Off-Site Construction) is a new construction method based on factory production. Researches such as OSC-related design and production standardization, transport methods are actively conducted in the U.S., UK and other parts of the world as this new method has an edge over existing methods in terms of productivity, economy and quality. As the emergence of this new area requires reasonable management, an analysis of the scope of construction project management is required accordingly. Therefore, this research analyzed the study trends and relationships at the CM/PM range’s “Operation level” to identify areas of study, relationship between studies and deficiencies in current research. This study carried out a comprehensive literature review of the OSC (CM/PM) research by analyzing 94 papers in Operation level as of September 3, 2018, and the analysis results are as follows. (1) Working stage level researches have been increasing rapidly since 2006. (2) Non-volumetric type is contributing most significantly at work stage level. In the building sector, it has been identified that problems such as residential: living, quality issues, non-residential: economic difficulties, factory: productivity problems have been addressed. (4) The Non-volumetric pre-assembly type dealt with the economic feasibility of residential and non-residential buildings, whereas the modular type was studied in regards to assembly quality. (5) From 2006, project management areas (e.g., quality, human resources, risks) have been expanded. It is expected that this research will help find new areas of research for OSC. If the analysis is carried out to the level of the industrial, corporate and project phases in the future, it is deemed that the overall research flow and area of the OSC industry can be identified.

This study aimed to evaluate clinical practice guidelines (CPGs) for ankle sprains using the Appraisal of Guidelines for Research and Evaluation II tool, using electronic databases (GIN, PubMed, EMBASE, NCKM, CNKI, CiNii, WanFang database, RISS, and SCOPUS), to suggest strategies for improvement in the future. The search was performed on April 23, 2021 and 10 CPGs were selected for evaluation. Three CPGs were recommended without modification (Class A scores), five were recommended with modification (Class B), and two were not recommended (Class C scores). The CPG domain that received the lowest score was “applicability.” The traditional medicine CPGs scored higher [Class A (<i>n</i> = 1) and Class B (<i>n</i> = 1)] than the conventional Western medicine CPGs [Class A (<i>n</i> = 2), Class B (<i>n</i> = 4), and Class C (<i>n</i> = 2)] and were considered to be more methodical. In the future, more research into traditional medicine is required.

To maintain water quality after water treatment, monitoring whether the quality of treated tap water quality changes is essential. However, current investigations are insufficient to prevent secondary contamination in drinking water supply systems. This study investigated Gyeonggi’s e apartment where a red water problem occurred and monitored the water quality and corrosiveness of the overall water supply system to the apartment from June 2021 to April 2022. In a comparison of drinking water quality after water treatment and the influent of the reservoir, turbidity and heavy metal concentrations were increased and residual chlorine was decreased due to increases in temperature. Correlation analysis and principal component analysis (PCA) indicated that a low level of residual chlorine may cause the abscission of Mn2+ and Fe2+ through microorganism activation, which also causes a high level of turbidity. The corrosion index (LI) in the influent of the reservoir tank was increased due to Ca2+ and temperature. These results indicate that the corrosiveness of drinking water and the deterioration of drinking water quality were mainly increased between the drinking water treatment plant and the reservoir tank’s influent. The findings provide clear evidence that it is essential to manage water supply systems and reservoir tanks to prevent the secondary contamination of drinking water.
