Due to the frequent occurrence of large-scale disasters such as recent earthquakes, the problem of the safety of old school buildings has emerged. The need to secure safety management technology through constant monitoring is increasing in an attempt to supplement old school buildings with weak disaster response capabilities. Traditional research is approaching the development of an existing sensor-based risk precursor information monitoring system. However, unlike this, in this study, we will focus on the development of a data analysis platform as part of the development of a continuous monitoring system that can be prepared for earthquakes, collapses, and fires, based on constantly measured data. For this reason, the development of a safety diagnostic algorithm based on the optimal sensor-attached points and sensor data reflecting the fragile characteristics of old school buildings was derived. Utilizing this, a message and action manual system for each management / use entity of school buildings after retirement was constructed.

상수도 시스템은 물을 수용가에 깨끗하고 충분하게 공급하는 사회기반시설 중 하나이다. 최근 상수도관로 노후화로 인하여 발생하는 누수, 적수, 단수 등의 피해를 방지하기 위하여 상수도관로 점검 및 진단을 수행하고 관 상태를 평가하여 해당 요소에 대한 보수 및 보강을 시행하고 있다. 하지만 기존의 정비사업은 관 노후도를 고려한 보강계획을 수립하여 효과적인 상수도 시스템 정비를 위하여 상수도관로에 영향을 미치는 수리 및 수질 평가를 통합적으로 고려한 보강 우선순위 결정이 필요하다. 따라서 본 연구에서는 상수도 시스템의 구조적, 비구조적 평가 인자를 동시에 고려한 시스템 보강 우선순위 선정을 위한 통합평가 기술을 제안하였다. 보강 우선순위 선정을 위하여 실제 상수도관로가 설치된 지역을 대상으로 상수도관로의 수리. 수질, 관 상태 등의 구조적 인자와 중요시설, 단수 시 피해인구 등의 비구조적 인자를 고려한 통합평가를 수행하였다. 구조적 인자 중 수리 및 수질 인자는 수리해석기법을 이용하여 기준치 통과 여부에 따라 평가하였으며 상수도관로의 관 상태는 관로의 제원, 매설 깊이, 노후도 등의 기준으로 평가하였다. 이러한 평가를 바탕으로 우선순위 선정을 위해 다기준의사결정법을 이용하여 상수도관로의 보강 우선순위를 선정하였다. 본 통합평가는 상수도관로의 구조적, 비구조적 위험도를 정량적으로 인지할 수 있을 뿐만 아니라 비구조적 인자를 고려하여 기존의 평가방법보다 더 신뢰할 수 있는 결과를 제공한다.

The Seoul Onsu Industrial Complex, having been completed over 50 years ago, is an old industrial complex, with deteriorating infrastructure and factory buildings. Despite this, there's a current urban industrial agglomeration centered on the machinery industry in the Seoul Onsu Industrial Complex. This study aims to holistically analyze the physical deterioration of facilities in the aging industrial complex and the characteristics of industrial agglomeration to derive the identity of the Seoul Onsu Industrial Complex. Based on the research findings, the complex is seeing an enhanced urban industrial agglomeration due to the influx of small-scale businesses resulting from concentrated trade networks in the metropolitan area and plot subdivision, permission for noise-producing processes, and the ease of securing highly-skilled technicians. However, this agglomeration coexists with a weakening of the complex's production function, limited innovativeness of resident companies, and non-innovative features resulting from weakened competitiveness in the metropolitan machinery industry. In summary, the identity of the Seoul Onsu Industrial Complex is a 'Non-Innovative Urban Industry Agglomeration', an old industrial complex, witnessing non-innovative agglomeration based on a machinery industry network centered in the metropolitan area.

Sewer rehabilitation is performed to improve the problem for urban drainage sewer system recently. However the data for the sewer system is not stored enough so that the sewer system is difficult to be managed systematically. In this study, a maintenance management system for urban drainage system is developed to store the data efficiently and manage the system systematically. In the developed system, a hydraulic and hydrologic analysis module is included to test the carrying capacity of a sewer pipe and estimate the amount of combined sewer overflows. The I/I and superannuation evaluation module is included in this system. The module distribute the total inflow/infiltration observed at the several sampling points in a drainage area to the individual pipes of the entire sewer system. Then the superannuation of a sewer pipe is evaluated according to the amount of I/I of the pipe. And in the developed system, the optimal rehabilitation priority module is included to determine the optimal priority and support the decision making for the sewer rehabilitation. The maintenance management system which is developed in this study is constructed by the association with the developed modules and the system is formed as graphical user interface system.

Given both structural safety and economic benefits of aging facilities, remodelling of the existing facilities is preferable to reconstruction. This recognition provides an opportunity to reduce the commitment of resources and national budget. However, when a subordinate troop asks for remodeling or reconstruction of a deteriorated facility, it is difficult to ensure the consistency and objectivity in the process of decision making for the alternatives due to the absence of systematic and quantitative rating methodology. Their economic evaluation methodology only exists in a manual format. Thus, further research is required for converting the methodology into an automated system in view of practicality such as rapid and accurate data processing. The contributions of this study are as follows: 1) Literature review found out a representative economic evaluation model focused on military facilities, and comparative analysis with a similar study identified the strength and weakness. 2) this study presented how to convert the theoretical framework which enables to solve a specific subject matter into an automated system. 3) it developed a user friendly interfaces which consist of four functional modules by considering the usability and accessibility of the system user. 4) the developed system was verified by a case study in terms of four kinds of performance indicators.
