Who Should Control the Integrated Management System for Sewerage Facilities in the Upper Reaches of Multi-Purpose Dams in Korea? 원문보기

Integrated management systems (IMS) that control entire sewerage facilities in the upper reaches of multi-purpose dams are being constructed for their efficient operation and management. However, because the IMS installed in a watershed belong to several local government bodies, significant conflict would be expected between stakeholders in the process of deciding who should control the IMS after completion of the construction that was initially implemented under the support of central government. The objective of this study was to suggest a decision making to determine who should control the IMS for sewerage facilities in the upper reaches of multipurpose dams in Korea, using the analytic hierarchy process (AHP). Three alternatives were selected to determine who should control the IMS for sewerage facilities: commissioning to public corporations, commissioning to private corporations, and a role-sharing partnership. In using the AHP technique, the emphasis was on comparing public interests, economics, efficiency, sustainability, specialty, grievance mediation and receptiveness. As a result, building a role-sharing partnership received the highest score. Commissioning to a special institute was also suggested as an alternative as this showed a score similar to that of building a role-sharing partnership.

문제 정의

In this study, an attempt was been made to compare different entity alternatives for the successful implementation of the management, operation and maintenance of the IMS for sewerage facilities in the upper reaches of multi-purpose dams in Korea. Three alternatives were considered in deciding who should control the IMS for sewerage facilities: commissioning to public corporations, commissioning to private corporations, or a role-sharing partnership.
Since the IMS installed in a watershed belongs to several local government bodies, significant conflict would be expected between local governments, inhabitants, non-governmental organizations (NGOs) and other related agencies as to who will be in charge of the IMS after completion of the construction that was implemented under the support of central government. Using the analytic hierarchy process (AHP), this study aimed to determine which entity should control the IMS for sewerage facilities in the upper reaches of multi-purpose dams in Korea.

제안 방법

A questionnaire, composed of pairwise comparisons, was prepared based on the predetermined hierarchical scheme and sent to experts (engineering consultants, operators of STPs, and university professors) engaged in the field of sewerage design and construction. In this study, 31 different individuals provided independent comparison values.

데이터처리

After receiving 31 answers, the analysis was performed using MS-Excel, with the rates of inconsistency for each factor evaluated. The CI was calculated as 0.

후속연구

The CI of the studied problem is compared with the average random index (RI) obtained from associated random matrices of order n to measure the error due to inconsistency [4]. As a rule of thumb, a consistency ratio (CR = CI/RI) value of 10% or less is considered acceptable, otherwise the pairwise comparisons should be revised.
The system was developed to save management costs and improve the efficiency of sewerage projects. It was also expected that the system would encourage not only higher efficiency of sewerage projects, but also the development of relevant technologies, such as information technology (IT) and environment technology (ET).

용어 설명: PCR은 세균 특이성이 있는 primer를 이용하여 적은 수의 세균이 있을지라도 쉽게 검출할 수 있는 유용한 방법이며, 이를 이용하여 구강 내 치면세균막이나 타액에서 직접 세균을 검출할 수 있게 되었다[8].
