Purpose - The purpose of this paper is to test the hypothesis that the fundamentals of the supply chain relationships have not changed during the digital transformation period in Korea between 2006 and 2018. Design/methodology/approach - The data for this study were collected through a questionnaire-based survey during two different time periods in Korea, 2006 and 2018. Findings - This study reveals that supply chain professionals in 2006 regarded trust building process as the most important construct for the successful supply chain operations while in the 2018 survey, trust-based commitment became the most important construct. This paper concludes that supply chain sustainability will be enhanced based on strong supply chain relationship framework. Originality/value - This study reaffirmed that a supply chain relationship built on a trust-based commitment is still the pathway to successful supply chain implementation. As far as we know, no studies have been published in examining supply chain relationships during the digital transformation in two time periods.

Radioactive liquid wastes are produced at hospitals from diagnostic and therapeutic applications of radionuclides. The most usual management of these wastes is temporary storage at the hospital for radioactivity decay and, then, discharge into sewage if not other pollutants are present in waste, always after authorization of the corresponding institution. In some cases, radioactive wastes have other hazards, such as chemical or biological ones, which can be more dangerous than radiological hazard, and do not allow direct discharge into sewage in spite of decaying activity below the clearance level. Therefore, these wastes have to be treated and condition before discharge in spite of activity decay below discharge limit. This is the case of liquid wastes from radioimmunoassay (RIA), a laboratory technique that allows to determine human substances in very low concentrations (below 10-12 g/mL), like hormones, using 125I as radionuclide. This study summarizes the usual management of radioactive liquid wastes from hospitals, including conventional and recent treatments applied. Furthermore, based on experimental results obtained with real RIA wastes, this work exposes a proposal of treatment with ultrafiltration and reverse osmosis membranes, and determines the most suitable application of this treatment according to radiological and operational considerations.

A large number of artificial-origin radionuclides from irradiation in small reactors and/or nuclear reactions in accelerators are currently used in non-nuclear industries such as education, oil and gas, consumer merchandise, research, and medicine. Radioactive wastes from the use of these radionuclides in non-nuclear industries include expired sealed radioactive sources, biological materials, radionuclide-containing chemicals, contaminated equipment, and very small quantities of used nuclear fuel. Although being less challenging and complex than nuclear energy production and research waste streams, these wastes are subject to the common nuclear regulations by the Canadian Nuclear Safety Commission, and are managed following domestic and international standards and guidelines made by the Canadian Standards Association, International Atomic Energy Agency, and International Organization for Standardization. Management practices used in the nuclear industry in Canada are commonly applied to the non-nuclear industry radioactive waste streams, such as waste handling, treatment, packaging, storage, transportation, clearance and exemptions, and disposal. The half-lives of radionuclides in non‑nuclear applications range from hours to thousands of years, and their activities in non-nuclear industrial applications can be as low as their clearance level or as high as the upper limits for intermediate level radioactive waste. Waste containing only short half-life radionuclides is placed in temporary storage to allow decay, and then is cleared and disposed of through non-radioactive waste routes. Non‑clearable waste materials are treated, consolidated, and managed along with radioactive waste generated from the nuclear industries at designated radioactive waste management sites.

Wildfires are a prevalent natural disaster that can significantly impact human populations and result in considerable losses. With a changing climate, wildfires in many countries have increased in intensity and frequency, making effective restoration efforts in affected areas crucial. This paper aims to evaluate the efficacy of ordered weighted averaging (OWA), a GIS-based multi-criteria decision analysis technique, in identifying priority areas for wildfire restoration. A case study using the 2009 Station Fire in California is presented, using the restoration criteria of slope, erodibility, proximity to forest cover, and proximity to surface water. By applying both importance and order weights, multiple OWA decision strategies with varying risk levels were examined. Different strategies greatly influence the spatial distribution of land considered high and low priority for wildfire restoration, each with varying levels of trade off. In the OWA decision space, placing full emphasis on the highest (best) values (using the risk-taking OR operator) or the lowest values (using the risk-averse AND operator) resulted in composite priority maps that cannot be recommended for practical use. More nuanced scenarios are achieved with the OWA operators representing a range of compromise decision strategies between these extremes. The OWA technique in GIS can thus help to explore the impact of decision-makers' risk attitudes in a wildfire restoration setting.

It is widely agreed that properly establishing a sustainable supply chain strategy to yield competitive advantages is essential for business enterprises, and a number of research papers on sustainable supply chains have been produced over the last two decades. However, many past studies on sustainable supply chain strategies emphasized either classification schemes or various coordination mechanisms, and few of them have focused on an integrated framework for sustainable supply chains. Therefore, the objective of this study is to develop a strategic framework for the sustainable supply chain management. The study is based on the abductive reasoning process through literature review to establish a strategic framework which is ranked through grey relational analysis (GRA). The weighted data of various strategies collected from the elite interview prove to be comprehensive and evaluable, so it can create values for supply chain members in practice. The results further suggest that each sustainable supply chain in different fields can select the best combination of strategies through GRA to constantly facilitate performance of sustainability. The main contribution is the submission of a strategic framework which makes up the insufficiency of past research papers lacking an integrated strategic framework. At the same time, the proposed strategic framework has also been illustrated through a case study.

Seeds of pea (Pisum sativum L. var. Alicia) were germinated for 5 d by soaking in distilled water or treated with cadmium and/or humic acid (HA). Interaction between humic acid and cadmium was previously discussed. However, the regulation of the humic acid / cadmium interaction during seed germination, the first crucial stage of the plant life cycle, need to be clarified. Seed germination is an important stage of the plant life, which is highly sensitive to surrounding medium changes, since the germinating seed is the first interface of material exchange between plant cycle and environment. Relationships among cadmium stress, HA-treatment, germination rate, and changes in reserve mobilization were studied. Cadmium disrupted the soaking process that was a major event of germination. Moreover, important solutes leakage due to Cd-treatment caused disorder in reserve mobilization from cotyledons to growing embryonic axes. The observed delay in germination rate and seedling growth after Cd-treatment could be explained, partially, by the disturbance in the mobilization of water and nutrients. NADH-and MDA-activities were considered as markers of oxidative stress. they were substantially increased after Cd-treatment compared with controls but decreased in presence of AH. Excessive NADH oxidase activities proved the install of oxidative stress in Cd poisoned seeds. We suggested an antagonist effect of Cd and HA on oxidative stress enzyme activities. Treatment of seeds with Cd and/or AH maintained a high level of guaiacol peroxidase activities during five days. The possible implication of GPOX against Cd toxicity and the improvement of the antioxidant system after AH treatment proved an important implication of these findings during germination.
以豌豆(Pisum sativum L. var. Alicia)种子为试验材料，采用蒸馏水浸泡或镉和/或腐植酸(HA)处理，使种子萌发5 d。腐植酸与镉的相互作用已在前面讨论过。然而，在植物生命周期的第一个关键阶段——种子萌发过程中，腐植酸/镉相互作用的调控需要澄清。种子萌发是植物生命的重要阶段，对周围环境的变化高度敏感，是植物生长周期与环境物质交换的第一个界面。研究了镉胁迫、ha处理、发芽率与储备动员变化之间的关系。镉破坏了浸渍过程，这是发芽的主要事件。此外，cd处理导致的大量溶质渗漏导致子叶到胚轴的储备动员紊乱。cd处理后的发芽率和幼苗生长延迟，部分原因是cd干扰了水分和养分的调动。nadh和mda活性被认为是氧化应激的标志。与对照组相比，cd治疗后它们显著增加，但存在AH时它们减少。过量的NADH氧化酶活性证明了Cd中毒种子存在氧化胁迫。我们认为Cd和HA对氧化应激酶活性有拮抗作用。Cd和/或AH处理的种子在5天内保持较高水平的愈创木酚过氧化物酶活性。GPOX抗Cd毒性的可能含义以及AH处理后抗氧化系统的改善证明了这些发现在萌发过程中的重要意义。

Despite the various initiatives being employed for fostering sustainability to globally achieve Agenda 2030, the understanding of the Higher Education Institutions (HEI) practices, discourse, and management remains limited. The present study identifies and quantifies the development of sustainable practices for HEI. It is an exploratory cross-sectional study conducted in 2014 at King Abdul Aziz University (KAU) to identify knowledge, attitudes, and behaviour concerning waste management and what could be done to develop sustainable practices at the campus. The study population comprised of academic and non-academic staff of KAU recruited through random sampling technique. The data was collected through two closed-ended questionnaires and analyzed using IBM Statistical Package of Social Sciences software (SPSS) version 20. The study's findings showed that waste management (WM) would improve KAU's reputation at local, national and international levels resulting in improved regulatory compliance. The results also reflected that environmental pollution caused by the emissions from the energy used and the materials consumed could considerably be reduced by the effective technical measures taken by the organization. The study concluded that sustainability in universities could be achieved when HEI works to inform citizens; there still is a long way to be at par with the European counterparts.

Green sustainable development is an extremely important concept, and the most representative industry is agriculture. The agricultural industry value chain covers the connotation of green and sustainable innovation. Circular agriculture is a revival of old agricultural practice, and the concept is a combination of crop planting and livestock farming to minimize the losses in the food production chain. This study explores the effects of Ganoderma lucidum compound added in feed on goat weight and anti-inflammatory through a case study. This study uses average weight difference analysis and an independent t-test to verify the goat weight gain and growth, and uses nitric oxide, interleukin 6, tumor necrosis factor α, and tetrazolium to verify goat health. This study shows that dietary supplementation of the Ganoderma lucidum compound has better performance in weight gain and growth of goats. It also provides a method of reducing antibiotics to promote health and welfare in the goat or even the livestock breeding industry. At the same time, it may help livestock owners to improve management efficiency.
