The total production of the smelted copper reaches 450,000 tons per year, and the production of copper-related goods grows year by year owing to the extension of facilities and the development of production techniques. On the other hand, the volume of slag discharges by-produced at the time of copper smelting process is also on trend of increase. The by-produced copper smelting slag amounts to 700,000 tons a year, which is one and half times of the total smelted copper production. Accordingly nobody disagrees that comprehensive researches on how to deal with and how to reuse the accumulated smelting copper slag have to be encouraged. Even though the possible uses of the copper smelting slag have being made on various levels at present as materials for iron powder cement, sand-blasting and fire-proofing rock wool, but a considerable volume of the slag is abandoned as unnecessary by burying or piling up in careless in the open ground.

This study empirically shows the effect of big data-based realistically predicted building lifespan on LCA through LCA analysis on waterproofing methods of real buildings. The lifespan of 17 real buildings was predicted with a machine learning prediction model, and LCA analysis was performed. As a result of this study, the accuracy of the LCA analysis results revealed a tendency to be irregular as the predicted lifespan percent error increased. Moreover, the percent error of the LCA analysis results of the buildings with a predicted lifespan percent error of 6% or less was 0%. The result of this study shows that the building life span prediction model with a limited prediction percent error according to the research purpose can guarantee accurate LCA results.

In the Public Notice No. 2019-15 of the Ministry of Employment and Labor, the safety net and regulations on them have been deleted. The performance criterion of the debris net, which also functions as a horizontal safety net in the regulations on the criteria of occupational safety and health, is unclear. When installing a debris net that also functions as a horizontal safety net, a net that meets the performance criteria of KS F 8082 must be installed in accordance with KOSHA C-31-2017. The Korean Standard Specification for Construction Works, which specifies debris net and horizontal safety net, should be revised as soon as possible.

노인장기요양보험제도를 도입한 지 10여년이 지나 돌봄의 사회화가 어느 정도 진전되었다고 평가하고 있는 지금도 여전히 돌봄 현장에서는 노인들의 인권이 이슈화 되고 돌봄 받을 권리는 무시될까? 돌봄의 가치는 왜 저평가되어 있을까? 돌봄에 대한 책임은 왜 여성들에게 전가되어 있고, 그들의 열악한 근무조건은 왜 개선되지 않는 것일까? 본 연구에서는 Kittay(1999)가 주장한 1·2차 돌봄관계에서 도출되는 ‘돌봄의 공공 윤리’를 분석틀로 평가절하된 돌봄의 사회적 가치 재평가와 함께, 노인장기요양보험 제도에 대한 돌봄의 사회화 정도를 평가하고 불평등한 돌봄의 전통적 성별분업구조와 돌봄 제공자의 노동여건, 그리고 돌봄거버넌스 참여 보장 정도를 살펴 보았다. 그 결과 공적 돌봄의 수준은 다소 부정적이고, 요양보호사의 임금수준과 근로여건은 열악하다. 돌봄의 주변화로 돌봄 당사자들이 정책 수립과 운영의 참여가 다소 제한되고, 그들의 욕구는 충족되지 못하는 등의 문제점이 나타났다. 이러한 관점에서 제도 발전을 위한 정책대안을 제시하였다. Even after more than a decade since the introduction of the Long-Term Care Insurance System, the socialization of care has progressed to a certain extent, why is the human rights of the elderly still an issue at the care site and the right to be cared for ignored? Why is the value of care undervalued? Why is the responsibility for care shifting to women, and why are their poor working conditions not improving? In this study, Kittay (1999) assessed the social value of care, which is evaluated as a social value reassessment of care derived from the 1st and 2nd care relationships, and examined the traditional gender division structure of care, care providers' labor conditions, and care governance. As a result, the level of public care is somewhat negative, and the wage level and working conditions of caregivers are poor. The marginalization of care has led to problems such as the participation of care parties in policy-making and operation is somewhat limited, and their needs are not met. From this perspective, policy alternatives for institutional development were presented.
BF 인증기준의 바닥 안전성에 관한 정량적 평가지표 검토

For Barrier-Free certification, the floor and ground surfaces must be finished with materials that are not slippery, flat, and have low-impact in fallis. However, the BF Certification Act does not provide specific methods to meet these regulations. In performance-based design, the responsibility of proving the performance rests with the building owner and architect, so quantitative evaluation indexes are needed to select suitable materials. Furthermore, changes in performance after completion should be checked periodically in 'As-Is' conditions. There are various methods for slips, trips and falls risk assessment, causing confusion for users. In this study, the results of previous studies on the evaluation methods of slips, trips and falls were considered closely, and each quantitative evaluation index that can be used in the new construction and maintenance phase was presented.

The following conclusions were reached through the research on the development of the required performance extraction tools for the application and utilization of various construction methods of lightweght dry wall. 1) Performance required for walls of apartment buildings can be divided into safety, habitation, durability and productivity. Among these, horizontal load resistance, shock resistance, anti-seismic performance, insulation, and acoustic characteristics are the main performance that correspond to dry walls. In addition, safety related to toxic gases and contaminants are required according to recent eco-friendly requirements. 2) To select a wall according to the required performance of an inner wall applied to an apartment, a map tool in the form of 2D matrices was constructed to enable the required performance to be applied, indicating that the wall location and wall material and its differentiating according to the old method.
