지구 환경문제가 국제적인 문제로 부상하면서 국제사회는 글로벌 이슈(기후 변화, 빈곤퇴치, 인권 등)를 해결하기 위해 지속가능발전이라는 새로운 패러다임을 제시하며, 17개의 지속가능발전목표(SDGs)를 실행하고자 다양한 조직적 노력을 시도하며 통합해오고 있다. 최근 파리기후협정과 SDGs 달성에 필요한 재원을 마련하고자 지속가능한 금융의 투자가 확대되며 비재무적 요소인 환경·사회·지배구조가 기업의 미래 경쟁우위와 수익성을 결정하는 중요한 무형자산이 되어, 국내외 기관 투자자와 자산운용사들은 ESG 성과를 기반으로 투자를 확대하고 있다. 본 연구의 목적은 기업의 사회적 책임활동과 ESG 성과 정보 공개를 요구하는 국제적 기준과 이니셔티브를 도출하고, 건설기업의 ESG 활동 및 성과 수준을 분석하고자 한다. 본 연구의 결과는 향후 건설산업이 코로사19 사태, 탄소 중립, 중대 재해 발생 등으로 당면한 위기를 극복할 수 있도록 ESG 생태계를 구축하고, 무형자산 측정 및 관리를 위한 플랫폼 개발의 기본 자료로 활용되어 녹색 금융이 주는 비지니스 기회와 일자리 창출 등 사회적 가치 실현에 기여할 수 있을 것이다.

본 연구는 교육품질에 직·간접적인 영향을 미치는 다양한 환경요소 중 음환경에 대한 내용을 W대학 인문대 소공연장의 리모델링 사례를 통해 분석하고자 하였다. 본 연구의 대상인 W대학 인문관의 소공연장은 강의전용 공간으로 리모델링하기에 앞서 적당한 울림이 필요한 공연장과 상대적으로 음성의 명료성이 중요한 강의실의 음향성능 차이를 인지하고 강의전용 공간에 적합한 실내 음환경을 조성하고자 하였다. 따라서 본 연구에서는 리모델링 전 음향성능 측정, 음향 시뮬레이션을 통한 마감재료 변경안 제시, 리모델링 후 음향성능 측정의 단계를 거쳐 리모델링에 따른 강의전용공간의 음향성능 개선안의 사례를 제시하고자 하였다. 이러한 과정은 추후 마감재 변경을 통한 강의전용 공간 등 교육공간에 적합한 실내 음향성능 확보의 사례로 활용될 수 있을 것으로 사료된다.

Korea's traditional house type, the Hanok, has been the essence of Korean domestic culture for hundreds of years. However, Hanok, have begun to disappear as result of urbanization. Because mud walls are crude and weak in water walls are also easily broken by impact. There are further problems in that construction cost is expensive and takes more time than modern house construction, and that the maintenance of Hanok is more difficult than people sometimes predict. Despite much interest in Hanok construction, there is a lack of in younger generation. Thus seeking new ways of maintaining Korea's traditional housing culture and extending Korean traditional houses is important. This study proposes directions for creating new residential environments for the future generation of Korea. A Dry-wall alternative to the Korean traditional mud wall is particularly needed. Dry-walling, made by sustainable materials such as mud board and wood, can strengthen the advantages and make up for the weaknesses of the Korea traditional mud wall. In this study, both wall types underwent various evaluations in terms of their performance in insulation testing, freezing and thawing testing, impacting testing and weight measuring (the size of material in this experiment was $69cm{\times}105cm$). On all of these tests, findings revealed that the dry-wall alternative performed better than traditional mud wall.

Damage detection and localisation in structures is essential since it can be a means for preventive maintenance of those structures under service conditions. The use of structural modal data for detecting the damage is one of the most efficient methods. This paper presents comparative performance of various state-of-the-art meta-heuristics for use in structural damage detection based on changes in modal data. The metaheuristics include differential evolution (DE), artificial bee colony algorithm (ABC), real-code ant colony optimisation (ACOR), charged system search (ChSS), league championship algorithm (LCA), simulated annealing (SA), particle swarm optimisation (PSO), evolution strategies (ES), teaching-learning-based optimisation (TLBO), adaptive differential evolution (JADE), evolution strategy with covariance matrix adaptation (CMAES), success-history based adaptive differential evolution (SHADE) and SHADE with linear population size reduction (L-SHADE). Three truss structures are used to pose several test problems for structural damage detection. The meta-heuristics are then used to solve the test problems treated as optimisation problems. Comparative performance is carried out where the statistically best algorithms are identified.

IT outsourcing providers has been expanded from a single functional system to the entire IT service to gain sustainable competitiveness. This new trend of IT outsourcing need outsourcing management capability based on a firm's core capacity. Hiring external IT service providers to manage part or all of its information-related services helps a firm focus on its core business and provides better services to its clients, thus obtaining sustainable competitive advantage. This research investigates the major factors that determine the level of a particular firm's success at IT outsourcing. Based on process innovation and core-competency theories, we identify three significant components of a firm's IT outsourcing management method (ITOMM): level of core-competency-based management, maturity of outsourced tasks, and maturity of outsourcing management. Comprehensive data collection was conducted through an outsourcing association. The survey data were analyzed using a structural analysis method. Maturity of outsourced tasks and maturity of outsourcing management were found to affect project performance directly, while level of core-competency-based management only indirectly impacted project performance through its positive impact on the other two ITOMM components.

The current study aims to classify what determines entrepreneurial leadership among small and medium enterprises (SMEs) in the Saudi Arabian context. It also attempted to recognize the role played by entrepreneurial leadership by supporting SMEs in the nation's sustainable economic growth. The study is based on a primary survey administered among SMEs in the Riyadh region of Saudi Arabia. Overall, 152 responses were collected. However, after data cleaning, only 107 were found to be fit for final analysis. Structural Equation Modelling using SmartPLS® Software was applied for analysis. The findings emerged from the study immensely concluded that entrepreneurial leadership is an essential instrument for managers/owners of the SMEs sector who aim to improve the efficiency of tasks and contextual performance in Saudi Arabia. The study came across that "ability to absorb uncertainty," "ability to build commitment," "the ability to frame the Challenge," "the ability of path-clearing," and "ability to specify limits," are the five constructs that help frame the entrepreneurial leadership in the Saudi context. The study suggests that leadership trainers, SME policymakers must focus on precisely these skills to inculcate the ability of entrepreneurial leadership among Saudi entrepreneurs, SMEs owners, and managers.

The incorporation of sustainability principles into the structural engineering design of buildings is increasingly important. Historically the focus of improvements to the environmental performance of structures has been operational energy considerations. Current research has highlighted the requirement for changing the approach by increasing the consideration of embodied energy in structures. This research was conducted to build on previous research by the authors in quantifying the contribution of column optimization to the embodied energy performance of concrete framed buildings. Ultimately, the authors intend to develop mechanisms through which sustainable design can be quantified, enabling alleviation prior to construction. Columns are a key structural element to consider as part of this development process. The outcomes of this assessment reinforced previous findings, observing that reduced structural weight as a result of other sustainable design measures carries manifold benefits include column design savings. Through the quantification of the embodied energy outcomes during this research phase, the columns were shown to contribute up to 19.71% of the total embodied energy of the structural system dependent upon construction technique used.

Electrostatic spraying is needed for today's sustainable farming. An electrostatic spraying nozzle was developed and its spraying performance was evaluated. High voltages of 15㎸, 20㎸, and 25㎸ were supplied for the electrostatic electrode. Artificial and real apple targets were used for the spraying experiments. Insulated material was used around the electrode to protect the loss of electrostatic effect. Three angles (0, 45, 90 degree) of spraying direction were used for the spraying test. The performance of electrostatic spraying was improved from 204.5% upto 429.2% on the apple targets.

최근 ICT분야가 다양한 환경에서 사용되면서 지속가능한 농업 환경에서는 ICT 기술들을 활용하여 농작물별 병충해 분석, 농작물 수확시 로봇 사용, 빅 데이터로 인한 예측 등이 가능해졌다. 그러나, 지속 가능한 농업 환경에서는 자원의 고갈, 농업 인구 감소, 빈곤 증가, 환경 파괴 등을 해결하기 위한 노력이 꾸준히 요구되고 있다. 본 연구에서는 지속 가능한 농업 환경 기반의 농작물의 생산 비용 감소 및 효율성을 증가하기 위한 인공지능 기반 빅 데이터 처리 기법을 제안한다. 제안 기법은 AI를 결합한 농작물의 빅 데이터를 처리함으로써 데이터의 보안성과 신뢰성을 강화하고, 더 나은 의사 결정과 비즈니스 가치 추출이 가능하다. 이는 다양한 산업과 분야에서 혁신적인 변화를 이끌어내고, 데이터 중심의 비즈니스 모델의 발전을 촉진할 수 있다. 실험과정에서 제안 기법은 다량의 데이터가 생성되나, 일일이 정답을 태깅하기 힘든 농장 현장에서, 소량의 데이터에 대해서만 정확한 정답을 부여하고, 정답이 부여되지 않은 다량의 데이터와 함께 학습하여, 다량의 정답 데이터로 학습했을 때와 유사한 성능(오차율:0.05 이내)이 나타났다.
