Particulate Matter(PM) is one of the most critical pollutant which can cause a fatal disease if the human body inhales. Construction is the business that emits the most fugitive dust. It is therefore necessary to manage construction site. South korea government focuses on the fugitive dust control measures defined in regulation being implemented properly. However the number of civil complaints related to fugitive dust emitted from construction site is the most in korea. So it is necessary to check from the management system aspect. This paper compares and analyzes the fugitive dust management system which applied to the construction site of major cities in three countries, and finds out what needs to be supplemented by the domestic management system.

To deal with the water pollution arising from the construction site, this study raises the issues of management and laws and it suggest the efficient way to reduce water pollution by through the case studies. In order to study, seven cases were selected from "Construction Environmental Management Best Practice Competition" co - sponsored by Construction Association of Korea and Construction Environment Association. As a study result, there are problems that depending on the characteristic of the construction site environment simple alone settling facilities can not handle muddy and dirty water generated by the construction site. However, when the construction site applied improved water pollution control facilities with reflecting the characteristic of muddy and dirty water. The problem can be solved moreover it can achieve exceeded emission standard. Therefore new regulations and management with water pollution control facilities considering characteristic of environment is needed to cope with water pollution arising from the construction site.

Understanding the current status of a construction project is necessary to achieve successful on-site management. Real-time information delivery is a major concern for construction industry practitioners in order to expedite decisions and discussions. We propose the use of a first personal view (FPV) system of a quadcopter drone as a tool for monitoring on-site status and communicating between construction participants. The most important function of the drone FPV system is its ability to visually monitor construction site situations in real time. An on-site management system process is developed, verified, and applied to several construction work tasks after determining factors that affect efficient construction management. The proposed system is expected to assist the construction manager in achieving high efficiency.

Purpose: This study tested the effectiveness of brochure- and video-based education on managing surgical site infections by operating room health personnel. Methods: From April 20 to May 4, 2021, 34 operating room health personnel were subjected to training on surgical site infection management using brochures and educational videos. A survey was then conducted on knowledge, perception, and adherence regarding surgical site infection management. Results: After receiving training on surgical site infection management, the knowledge score increased significantly (15.15±2.09 vs.19.70±1.96, p<.001). However, the perception and adherence scores were already near perfect before the intervention and did not further increase after the intervention. Conclusion: It is necessary to develop and utilize continuous and substantive educational programs to improve perception and adherence of surgical site infection management.

Site index is the essential tool for forest management to estimate the productivity of forest land Generally, site index equation is developed and used by relationship between stand age and dominant tree heights. However, there is a limit to use the site index equation in the application of variable ages, environmental influence, and estimation of site index for unstocked land. Therefore, it was attempted to develop a new site index equations based on various environmental factors including site and topographical variables. This study was conducted to develop regional site index equations based on the relationship between site index and soil factors for Pinus densiflora. Environmental factors that obtained from GIS application, were selected by stepwise-regression. Site index Equation was estimated by multiple regression from selected factors. Four environmental factors were selected in the final site index equations by stepwise regression. It was observed that coefficients of determination for site index equations were ranged from 0.34 which seem to be relatively low but good enough for estimation of forest stand productivity. The site index equations developed in this study were also verified to be useful by three evaluation statistics such as model's estimation bias, model's precision and mean square error type of measure.

건설공사가 대형화, 복잡화 그리고 전문화 되어감에 따라 공사의 정보도 양적으로 팽창하고, 질적으로도 고도 전문화되어 가고 있으므로, 공정관리를 보다 효율적으로 관리하기 위한 전산시스템의 필요성이 대두되고 있다. 현재는 현장사무소에만 전산시스템을 도입하여 공정관리를 수행하고 있으며, 공정관리를 위한 데이터를 입력하고 확인하는 작업은 건설현장에서 현장사무소까지 직접 도보로 이동하여 처리하고 있다. 이에 따라 본 논문에서는 건설현장과 현장사무소를 이어주는 무선통신시스템을 구축하고, 건설현장에서 PDA를 이용하여 즉각적으로 본사의 데이터베이스에 공정데이터를 입력하고 확인할 수 있는 응용프로그램을 개발하였다. 이를 통해 기존의 건설현장에서 이루어지던 공정관리를 개선하여 인력, 장비, 시간, 비용 등을 절감할 수 있는 효과를 기대할 수 있다.

Forest timber production potential of any site is oftentimes measured quantitatively by site index, which is defined as dominant height of a particular stand at a specified age. A site index was developed for estimating site quality of monoculture Pinus caribaea plantations in southwestern Nigeria using a base age of 25 years. Dominant height data were collected from 60 Temporary Sample Plots (TSPs) of $20{\times}20m$ in plantations of 15 to 37 years. Linear and non-linear models as been widely applied in quantitative forest measurements were fitted to dominant height-age data and the best site index equation is : $SI=Exp^{(InHd-23.495(A^{-2}-0.04)}$. The site index curves constructed for the three sites (Omo Forest Reserve - OFR (J4), Oluwa Forest Reserve - OLFR and Shasha Forest Reserve - SFR) across the southwestern Nigeria using the chosen equation revealed that a 15 year old Pinus caribaea in the study area attained average dominant heights of 25, 22 and 21 m in OFR (J4), OLFR and SFR respectively. The site index equation and curves proffer veritable insight into better silvicultural options and management practices for the future plantations suitable sites.

Construction companies are now trying a variety of cost-cutting strategies in the midst of recent slump of construction market. Notably, contract workers and local hires are accounting for increasing portion of management manpower as a part of their cost-reduction drive. However, construction site manpower researches to date have focused primarily on productivity analysis of site laborers, with little attention to the productivity of site management resources. This study aims to analyze the staffing status of office building construction site management manpower in reference to project size. Conclusions herein will provide basic inputs for subsequent attempts to build a model to enable efficient staffing of construction site management manpower.

As there are more accidents which are more serious in construction site than other industries, it needs the safety management system to be SLIM on the same time, There are still lots of difficulties to prevent those accidents exactly, so it also needs a safety supervision team to prevent the accident, unsafe operation and condition before happening, which is also called as a Man-to-Man safety management method. The range of the job site in one personnel's management is very big and large, so it needs the personnel to keep watch the safety operation and prevent any unsafe/fire accidents. Also the personnel also should find out the unsafe points in the job site, and carefully supervise the dead angle site, then support the totally safety management POINT and realize the ZERO accident.

토목공사 발주기관은 공사현장이 대부분 원거리에 위치하고 담당공무원도 다수의 현장을 관리하게 되므로 간접적 방식으로 현장을 관리하고 있다. 토목공사 현장은 광범위한 작업구역을 가지므로 현장 실무자의 보고에 의한 간접적 관리방식으로는 사업전체의 현황을 신속하게 파악하기가 쉽지 않다. 이러한 문제점을 해소하기 위해 발주기관과 현장간의 현장관리시스템은 오프라인에서 온라인방식으로 변화되고 있다. 본 연구에서는 UAV에서 취득한 현장의 3차원정보를 활용하여 원거리에 위치한 현장과 감독기관간에 관련 정보를 온라인으로 공유할 수 있는 개선된 현장관리시스템을 제시한다. 이를 위하여 연구에서는 다수의 실제 현장의 현장관리 운영체계의 문제점을 분석하여 UAV활용 현장관리시스템에 필요로 하는 공사현황보고 및 온라인 정보관리 등의 주요기능을 도출하였다. 연구에서 개발된 시스템은 실제 공사 중인 현장에 적용하여 활용성을 검증하였으며, 다수의 현장 조사를 통하여 기존의 간접적 현장관리 방식과의 효율성 개선사항을 분석하였다.
