The purpose of this study is to draw out objective bases for selecting various applicable facilities in case of the establishment of rainwater management strategies. To do so, sixteen facilities were selected from decentralized rainwater management systems that induce rainwater infiltration and detention as well as centralized end-of-pipe type infiltration and detention facilities in local areas. With these facilities, it attempted to evaluate them in terms of sustainability, pollutant elimination, flood control capacity and costs and subsequently analyzed correlations between each characteristic. The outcomes of the analysis were as follows: First was the analysis of characteristics between decentralized rainwater management systems and end-of-pipe rainwater management systems. From the decentralized rainwater management systems, the mulden-rigolen system and grass swale at street level had the highest in the total of the four items while the totals of the underground detention tank and temporary detention site were highest in end-of-pipe rainwater management systems. After analyzing the correlation between different types of facilities and each variable, it can be said that decentralized rainwater management systems have a higher correlation than end-of-pipe rainwater management systems in terms of sustainability whereas the latter are better in flood control capacity than the former. Second, the analysis of correlation in variables of each facility is as follows: first, there is a negative correlation between sustainability value and flood control capacity value; and there is a positive correlation between flood control capability and pollutants elimination. In addition, it revealed that the higher the flood control and pollutant elimination capability the higher the facility costs. Based on these assessments, it is possible to use them as objective selection criteria for facility application in case of site development project or complex plan.

The purpose of this study is to provide basic data for habitat restoration by implementing a series of processes of capturing and translocating Kaloula borealis and managing them in artificial breeding facilities. The study site in Samcheon, Jeonju-si, Jeollabuk-do was a waste landfill site in the past, and Kaloula borealis was found during the Samcheon Ecological River Restoration Project around March 2018. To restore the habitat, a plan was established to capture, translocate, artificially breed, and release Kaloula borealis at the site. The capture methods of adult Kaloula borealis were pitfall trap and drift fence, direct capture, and deep barrels. During 2018-2019, 86 adults of Kaloula borealis were captured and translocated to artificial breeding facilities. VIE-tagging was inserted under the skin for monitoring. For artificial breeding, Gryllus bimaculatus with oyster powder and vegetables were regularly supplied to feed Kaloula borealis. At the end of October 2020, 150 young Kaloula borealis raised in artificial breeding facilities were found not entering hibernation, so they were managed in a separate artificial breeding facility. Some young and adult Kaloula borealis currently hibernating will be scheduled to be continuously managed in artificial breeding facilities and released to the restored habitat in the spring of 2021.

Coastal and fishing facilities are gradually deteriorating in function due to the continual accumulation of soil sediments, which has affected local economic activities. Currently, there are many methods to remove soil sediments, but these methods are either a temporary solution or require a repetitive removal of the soil sediments, which is a huge financial burden for the maintenance of the facilities. To solve these problems, this study proposed a non-power soil cleaning system and evaluated field applicability by carrying out field model tests. The conditions for the evaluation focused on the drainage-elapsed time and drainage-outflow velocity according to the water level change in the water tank. In the field test, silty clay and sand were separately installed, and sedimentation soil removal test was practiced. As a result, the system was verified to have a sufficient outflow velocity for the removal of soil sediments. In addition, a generalization equation that can be used in different regions of the tide was suggested in this study. These results will greatly contribute to removing soil sediments in ports and dike gate facilities on the southwest coast. Since the system is an eco-friendly technology that does not require additional energy, thus it is expected to contribute to maintenance of sustainable facility performance as well as economic effect in the future.

The Korean government has been encouraging 'continuous' post-pump priming project management through relevant local personnel planning, action, and management, upon the selection of 68 sites for urban regeneration as part of the New Deal Project. This study assessed the utilization characteristics of containers, the socio-experimental temporary occupation facilities, as a tool for 'sustainable' urban regeneration. This is to identify the potential limitations of urban regeneration by the utilization of containers as public sector temporary occupation facilities and to provide adequate directions based on its efficacy. By comparing three Korean cases with the Japanese WaiWai project, in terms of 10 elements, the preoccupations with the social trend and scenery, and undifferentiated functions of the facilities focusing on the commercial or working aspects have been identified as limitations of Korean cases. Based on the analyses, the following are suggested as plausible approaches to utilize socio-experimental containers for sustainable urban regeneration: 1. Planning and management should be done by the same organization because the absence of the planning party's participation in the management likely leads to the pursuit of only profits. 2. Diversification and combinations of different utilization purposes of a single site and numerous planning of experimental container uses are in need. 3. Accommodations of heavy commercial uses lead to a decline in the continuity of follow-up projects and a change in the urban regeneration directions. Therefore, it is important to include a public socio-experimental program rather than a simple commercial or promotion program for the following urban renewal project.

Most of buildings have been deteriorated with time-elapse by reflection of the building location, material, environmental circumstances and so on. The performance would go down and be demolished if anything could not be done after constructed. The maintenance should be required to preserve a decent living condition or improve a inferior condition by various plans and practices. The maintenance plan needs various data such as a repair scope, a repair time, a forecasted cost, a plan of management and so forth. Among the above required data for planning the maintenance, the deterioration characteristics of the building components would be first analyzed. The deterioration pattern would be a key role to affect and make a maintenance plan. In this paper, it aimed at classifying the deterioration patterns of building components. A deterioration pattern would be analyzed between the cumulative repair cost and time-elapse and modeled with these relations. A deterioration patterns are classified into 4 types-a accelerated type, a straight type, a temporary type and a slowly type. As a result of this research, a accelerated type includes window, window frame, general paintings, general water proofing in building components. A straight type includes the lacquer paintings, furnishings in building components and water supply pipe, boiler, sanitaries in mechanical facilities and lighting in electric facilities. Based on these research results, further study should be conducted to include any other components and an estimating model.

The Clonal Selection Algorithm (CSA) is an algorithm inspired by the human immune system mechanism. In CSA, several parameters needs to be optimized by large amount of sensitivity analysis for the optimal results. They limit the accuracy of the results due to the uncertainty and subjectivity. Adaptive Clonal Selection (ACS), a modified version of CSA, is developed as an algorithm without controls by pre-defined parameters in terms of selection process and mutation strength. In this paper, we discuss the ACS in detail and present its implementation in construction site utilization planning (CSUP). When applied to a developed model published in research literature, it proves that the ACS are capable of searching the optimal layout of temporary facilities on construction site based on the result of objective function, especially when the parameterization process is considered. Although the ACS still needs some improvements, obtaining a promising result when working on a same case study computed by Genetic Algorithm and Electimze algorithm prove its potential in solving more complex construction optimization problems in the future.
