An integrated sewer management system was developed for the analysis of sewer flow and for optimal operation of sewer works using ArcView and SWMM. SWMM and ArcView were dynamically linked together using Avenue in order to construct user-friendly management system. The developed system was applied to a residential area in Choonchun city to verify its utilities. All the relevant field data were analyzed on the basis of developed system, and the modeling of sewer flow was implemented using RUNOFF, EXTRAN, TRANSPORT in SWMM. This system is now in the process of connection to the management system of watershed and surface environment in order to develope an integrated environmental management system. Futhermore, this system will be a critical part of overall control system of sewer works including sewer line and wastewater treatment plant. As this system can provide comprehensive prediction of flow and pollution profiles, it could serve as a tool not only for optimal management, but also for decision support system to examine the efficiency of planning and implementation of sewer projects.
Web Based Comprehensive Environmental Control Engine
김준현,Kim, Joon Hyun Kangwon National University 1999 産業技術硏究 Vol.19 No.-
This paper is aimed at the development of comprehensive environmental management system, which can be operated on the basis of world wide web. This study has been initiated as a topic of G7 project in 1988, and will be accomplished in 2001. Even thought there should be lots of works remaining to achieve this goal, preliminary products can be summarized as follows : 1) integrated environments information management system, 2) web based control engine, 3) surface water environment management system, 4) subsurface water environment management system, 5) sewer and waterworks management system. The core methodology of the engine is the generalized multidimensional finite element matrices to depict the terms in the analysis of various partial differential equations. Spatial information management system (ArcView) and Visual Basic were extensively employed to construct GUI oriented web based engine. Developed systems were consist with very intense computer codes due to the necessity of combinatory management of environmental problems. The web based engine could be served as a decision tool for the integrated management of environmental projects in Korea.
공간정보시스템과 지하수모형을 결합한 지하환경관리시스템의 구축

This study was performed to develop an information processing system for the sound conservation of soil and groundwater resources. The system contains the geographic spatial information system(GSIS), and the numerical model of groundwater flow and contamination. Numerical models (MODFLOW, MOC3D, MT3D, PMPATH, PEST, UCODE) and GSIS(ArcView) were integrated for the construction of an integrated management system of subsurface environment. The developed system was applied to the management of three mineral water companies located in clean mountain area. The impact of pumping over the overall catchment basin was modeled using the developed system for the decision of future management criteria.

Purpose: To compare the results of two different incision methods: scleral tunnel vs clear cornea in cases phacoemulsification and posterior chamber intraocular lens implantation combined with pars plana vitrectomy. Methods: Between August 2003 and August 2005, 61 eyes with cataract and vitreoretinal diseases were treated by phacoemulsification combined with pars plana vitrectomy and PC-IOL implantation. Preoperative demographic data and postoperative best-corrected visual acuity (BCVA), astigmatism change, and complications were analyzed. Results: The mean age of patients in the scleral tunnel incision (Group 1) and clear corneal incision (Group 2) was 57.09±13.72 and 58.83±11.83 years respectively. Diabetes mellitus was the most common underlying disease resulting in vitreous opacity. Vision improved in 82% of Group 1 and 78% of Group 2. There was a significant difference in the postoperative astigmatic changes between Group 1 and 2 (1.37±1.13D vs 0.78±0.67D). No discernible differences such as recurrent vitreous hemorrhage, inflammation in anterior chamber, increased intraocular pressure or iris changes were noted between the two groups. Conclusions: Although there was no difference in the postoperative BCVA, two different incision methods yielded significant different postoperative astigmatic changes.
