Purpose - Although the importance and necessity of "sustainable supply chain management (SCM)" is emphasized, it is often not realized due to conflicting results, the long time required, and large-scale changes brought about by sustainability. This study used the innovation resistance model to confirm the influence of sustainable SCM innovation resistance factors and dynamic capabilities on adoption intentions. This approach made it possible to understand the factors that hinder adoption of sustainability practices and to identify the relationships among influencing factors. It should also help to establish effective policies or strategies. Design/methodology - Through a literature review, the characteristics of sustainable SCM were classified into relative advantage, compatibility, perceived risk, and complexity. The effects of these innovation characteristics on innovation resistance in sustainable SCM and the effects of innovation resistance on adoption intentions were confirmed. In addition, the effects of SCM capabilities on innovation resistance and adoption intentions were analyzed, and the mediating effect of innovation resistance was analyzed. Findings - Compatibility, perceived risk, and flexibility had significant effects on innovation resistance. In turn, innovation resistance had a significant effect on adoption intention, and flexibility had a significant effect on intention to adopt. A partial mediating effect of resistance to innovation was confirmed. Originality/value - Although many previous studies have acknowledged trade-offs with sustainability, most sustainable SCM studies dealt with the correlations among positive drivers of adoption, practices, and performance. This study confirmed the process of accepting sustainable SCM innovation in a single model and is expected to serve as a cornerstone for future sustainable SCM adoption studies. In addition, our findings should help establish effective policies or strategies to activate SSCM adoption by identifying the factors that hinder the adoption of sustainable SCM.

Ethiopia is branded as the Water Tower of Africa because of its abundant inland water bodies that may be used sustainably to boost the economy. This review article's goal is to examine the current status and future potential of Ethiopia's fisheries, with a special focus on reservoirs. There are 200 known fish species (194 native, 40 endemic, and 11 exotic) in in Ethiopia's inland water. Ethiopia's fish production has increased by a factor of more than five in the past three decades (3,500 tons in 1983 to 15,681 tons in 2000 and 18,058 tons in 2010). However, fish produced in reservoirs is too low (8,059 t/year). The current fish harvests from reservoirs are significantly below the predicted potential yield, accounting for only 35% of the calculated fish production capacity. In this review, 14 potential reserves were revealed. A total of 48 fish species have been reported in these, of which 26 species (or around 54%) are present in Alwero reservoir. 19 of the 48 species that have been officially recognized belong to the Cyprinidae family and made up nearly 40% of the fish population in Ethiopian reservoirs. There has been, however, a decline in the productivity of Ethiopia's reservoir fish. Hence, actively start fishing in the numerous reservoirs that have been neglected yet, link the potential of fisheries and the benefits of the fish farming supply chain, let's begin building several other reservoirs similar to the Grand Ethiopian Renaissance Dam and beginning mechanized-based fish harvesting.

Purpose - Our previous study (Chang & Lee, 2023) presented observations on the recent changes in the year-on-year (YoY) Consumer Price Index (CPI) of the Republic of Korea (ROK) after the COVID-19 pandemic. The purpose of this article is to present an integrated analysis and interpretation of the recent changes in CPI and the Aggregate Import Price Index (IPI) by incorporating recent data, specifically data from September 2022 to December 2022. Design/methodology/approach - This study collected CPI (YoY) data in the ROK from January 2019 to December 2022 using e-National Indicator System provided by the ROK. Statistical analysis was employed to analyze the data. Findings - First, we confirm the extended results of the existing study by Chang and Lee (2023). Second, we demonstrate that the Aggregate IPI in ROK increased significantly in 2022 compared to 2021. We then provide an integrated interpretation on the significant increase in CPI and aggregate IPI in ROK, which complements Chang and Lee (2023) that limits their discussion to YoY CPI. Moreover, we show that the IPI of the semiconductor in ROK decreased significantly in 2022 compared to 2021. Research implications or Originality - Our results provide important insights into the recent changes in the CPI in the ROK. The results suggest that these changes can be partially attributed to various factors, such as the global supply chain disruptions resulting from the spread of the COVID-19 pandemic and the prolonged war between Russia and Ukraine, the side effect of quantitative easing by the US Federal Reserve, heat waves and droughts caused by climate change in ROK, a surge in demand following a gradual daily recovery, US-China trade conflict, etc. Our study shows statistically comprehensive results compared to the studies that limit their discussion to YoY average growth rate.

To realize the traceability of sustainable textile products, this study presents a low-carbon process through energy savings in the textile material manufacturing process. Traceability is becoming an important element of Life Cycle Assessment (LCA), which confirms the eco-friendliness of textile products as well as supply chain information. Textile products with complex manufacturing processes require traceability of each step of the process to calculate carbon emissions and power usage. Additionally, an understanding of the characteristics of the product planning-manufacturing-distribution process and an overall understanding of carbon emissions sources are required. Energy use in the textile material manufacturing stage produces the largest amount of carbon dioxide, and the amount of carbon emitted from processes such as dyeing, weaving and knitting can be calculated. Energy saving methods include efficiency improvement and energy recycling, and carbon dioxide emissions can be reduced through waste heat recovery, sensor-based smart systems, and replacement of old facilities. In the dyeing process, which uses a considerable amount of heat energy, LNG, steam can be saved by using "heat exchangers," "condensate management traps," and "tenter exhaust fan controllers." In weaving and knitting processes, which use a considerable amount of electrical energy, about 10- 20% of energy can be saved by using old compressors and motors.

최근 '신표준경제'(New Standards Economy)라는 말이 나올 정도로 지식기반경제에서 (기술)표준은 국가경제 및 산업, 그리고 기업경영에 있어서 핵심요소로 부각되고 있다. 본 연구는 표준 및 표준화의 개념을 검토하고, 표준과 기술혁신의 연관성에 관한 경제이론을 재구성하였다. 즉 표준과 기술혁신의 연관성을 표준의 경제적 기능에 따라서 정리하고, 제품 및 공정의 차원, 기업혁신활동 차원, 그리고 국민경제적 차원에서 각각 살펴보았다. 이를 통하여 도출된 몇 가지 결론 및 시사점은 다음과 같다. 첫째, 표준은 그 기능(호환성, 품질확보/안전성, 정보제공, 다양성 감소)에 따라서 기술혁신에 미치는 효과가 상이하게 나타나며, 특히 기술혁신의 장애요인으로 작용할 수 있다. 예를 들어 호환성 표준의 경우 구기술에서 신기술로의 전환을 방해하는 잠김효과(lock-in effect)를 가져오며, 다양성 감소표준은 말 그대로 범위의 경제를 축소시킨다. 둘째, 표준 및 표준화는 제품혁신 및 공정혁신 측면에서도 긍정적인 역할을 수행한다. 셋째, 표준은 R&D활동, 생산 및 제조활동, 시장침투 및 확대, 공급사슬, 기술이전 등 기업혁신활동의 전 단계에 걸쳐 기술혁신을 촉진시키므로 이를 고려한 기업과 산업의 전략, 더 나아가서 정부의 R&D정책이 요구된다. 넷째, 국가혁신시스템(NIS) 관점에서 볼 때 표준은 인프라기술(infra-technology)로서 공공재적 성격을 가지므로 정부는 표준 및 표준화제도에 대한 적정투자 수준을 결정해야 한다. 이와 같은 표준과 기술현신의 연관성에 대한 이론적 논의를 토대로 향후 구체적인 가설설정을 통해 실증적인 검증이 요청된다.

모듈러 건축공법은 공장 생산, 운송, 현장설치 프로세스를 통해 기존 현장중심 건축공법에 비해 품질향상 및 공기단축이 가능한 특징을 가지고 있다. 특히 모듈러 유닛의 제작과 시공이 분리되어 수행되기 때문에 다수의 프로젝트가 동시에 수행될 경우 각 프로젝트에 따라 생산해야하는 모듈의 크기, 수량, 납기일, 생산 유형 및 과정을 고려하는 SCM(Supply Chain Management) 관점의 공장 생산 공정 계획 수립이 필요하다. 그러나 현재 모듈러 유닛 공장 생산 계획은 개별 프로젝트 중심으로 수립되고 있어 다중 모듈러 건축 프로젝트 수행 시 모듈러 유닛 제작공장의 한정된 자원과 설치 현장별 프로젝트 요구조건들을 동시에 고려한 공장 생산계획을 도출하는데 한계가 있다. 따라서 본 연구에서는 다양한 변수 간 상호 연계성 및 제약조건으로 공정 계획 최적화 결과 도출이 가능한 유전자 알고리즘 방법을 통해 모듈러 유닛 제작공장의 한정된 자원과 설치 현장별 요구사항이 반영된 모듈러 유닛 공장 생산 공정계획 최적화 수립 모델을 제시하며 이를 사례분석을 통해 검증하였다. 연구 결과, 기존 다중프로젝트의 공장생산계획에 비해 평균 7.9%의 현장설치 공기단축 및 43%의 최대 야적장 이용률 감소가 가능하였다. 향후 본 연구 내용을 바탕으로 제약 조건 범위 확장 및 생산성 데이터 추가가 될 경우 다중 모듈러 건축 프로젝트의 모듈러 유닛 공장 생산 계획 수립과 현장시공프로세스 구축을 동시에 지원할 수 있는 기초 자료로 활용될 수 있다.

The question of how to establish sustainable agricultural systems has become as prominent as questions related to water, energy and climate change. High input/high output agriculture has brought with it many adverse effects; the massive deterioration of soil and water in both quantity and quality, increased greenhouse gas emissions and an increased prevalence of unsafe foods. Additionally, urbanization and climate change has worsened the shortage of farmland and reduced the supply of agricultural water. Given these challenges, maintaining, conserving and efficiently using agri-environmental resources, through fostering of sustainable agriculture, have emerged as key tasks in solving these problems. What is needed therefore is research, based on systematic and comprehensive empirical analyses, that can propose plans and methods for establishing an appropriate sustainable agricultural system. The empirical analysis of sustainable agricultural system is approached separately from economic, environmental and social aspects. An analysis of environment effect reveals that the available phosphate level is 1.3~2.1 times greater than the optimal amount in rice paddies, upland fields and orchards. Further examination has revealed that the excess nutrient is polluting both ground water and surface water. Analytical results for economic feasibility show that factors of production have been invested heavily in the rice crop. Under these conditions, sustainable agriculture, including low-input agriculture, appears to be a possible alternative that will facilitate simultaneous improvements in both economic feasibility and environment effects. Analysis results for sociality reveal that social factors include the value of producer, association and interior networks. Social conditions are comprised of leadership, consumers' awareness, education and conflict solutions. In addition, analysis as to the degree investments contribute to improving agricultural value added has revealed that the direct payment program is the most effective instrument. Experts confirm that economic feasibility can be improved by scientific and well-reasoned nutrient management on the basis of soil testing. Farmers pointed to 'economic factors' as being the largest obstacle to switching to the practice of sustainable agriculture. They also indicate 'uncertainty with regards to sustainable agriculture technology' as an impediment to practicing sustainable agriculture. Even so, farmers who believe environmental and regional issues to be the most pressing problems have expanded their practice of sustainable agriculture. The keys to establishing sustainable agriculture system are classified into the following four aspects. Firstly, from an economic aspect, the research indicates that agricultural policy needs to be integrated with environmental policy and that the function of market making based on the value chain needs to be revitalized. Secondly, from an environmental aspect, there is a need for an optimal resource management system to be established in the agricultural sector. In addition, sustainable agriculture practice will need to be extended with attendant environmentally-friendly and sustainable intensive technology also requiring further development. Thirdly, from a social aspect, green agriculture management needs to be fostered, technology and education extended, and social conflict mediated. Lastly, from a governance aspect, it will be necessary to strengthen good governance, assign and share suitable roles and responsibilities, build a cooperation system and utilize community supported agriculture.
