Purpose - As globalization progresses, complexity also increases, and various factors that threaten port functions are emerging. Accordingly, the demand for port security to prevent the crisis and resilience that quickly recovers its original function after the crisis is also increasing in port operations. However, few studies have examined how to ensure the port security and how the resilience affects operation performance of port and sustainability performance as well. So the study aims to find out how port security affects port resilience and port operational performance, and consequently, this two factors affect socioeconomic and environmental sustainability performance respectively and synthetically. Design/methodology - Confirmatory Factor Analysis (CFA) was first performed to determine the validity of the factors of model and hypothesis test was performed using Structural Equation Model (SEM) to analyze the Port Performance Model, which show the perception logic among port security level, port resilience, operation performance, and sustainability performance. In order to empirically analyze this model, total 264 respondents from port security operators, shipping companies in South Korea were surveyed. Findings - As result of SEM, First, port security level positively affected the resilience (H1) and cargo operational performance (H2) but not in both of the sustainability performances (H3, H4). Second, resilience positively affected only cargo operational performance (H5) and socio-economic sustainability performance (H7). Last, cargo operation performance positively affects the both of sustainability performances (H8, H9). Originality/value - It was confirmed that port security could improve cargo operational performance through ensuring port resilience and eventually increase the socio-economic sustainability. Therefore the study implies that careful integration and management of port security, port resilience, and sustainability are required, along with compromise on sustainable development goals in the social, economic, and environmental area among all stakeholders.

Purpose: The objective of this study was to explore operational definitions and moderators of the resilience of adult children of alcoholics (ACOA) and its associated variables. Methods: This integrative review was conducted based on a literature review method suggested by Whittemore and Knafl. Databases including PubMed, CINAHL, PsycINFO, and RISS were searched using the combinations of search terms such as; 'adult children of alcoholics,' 'parental alcoholism,' 'resilience,' and 'children of alcoholics.' Results: Seventeen studies were selected for this review. Findings of integrative reviews reported operational definitions for the resilience of ACOA and moderators. The operational definition of ACOA's resilience is: (1) having no behavioral and emotional problem, (2) meeting social and developmental expectancies, (3) having the ability to cope with adversity, (4) having high self-concept, and (5) having a meaningful relationship. In addition, the varying environmental moderators include family communication, qualities of caring environment, parental communication, parentification, and social support. Several moderators were identified as positive effect, self-esteem, alcohol-specific coping style, locus of control, spirituality, the image of God, and dyadic cohesion in marital communication. Conclusion: Our study findings emphasize comprehensive understanding of diverse definition of resilience and moderators in developing nursing interventions to promote resilience in ACOA.

Corporate longevity is an interesting issue from a theoretical point of view. In today's uncertain economic climate, the first priority for a company is survival. The longevity of an organization is basically one of the areas that can classify the sustainability of a company. Known as the cultural heritage of Indonesia, the traditional herbal medicine industry faces challenges of longevity. The word Jamu is a generic expression for traditional herbal medicine in Indonesia. The Jamu industry as Indonesia's cultural heritage must be preserved with good support from a technical, regulatory, and commercial perspective so that Jamu companies do not go into the decline stage. Operational resilience is usually defined as the ability of an organization to adapt rapidly to changing environments. This study aims to identify the effect of operational resilience and human capital on corporate sustainable longevity through innovation performance. The questions are addressed through empirical research of 108 small companies that produce Jamu, traditional herbal medicine in Java, Indonesia. This study was conducted during July-September 2020. Data analysis is carried out with SEM-PLS using SmartPLS software version 3.0 to evaluate the data collected. The results indicated that operational resilience influences corporate sustainable longevity directly and indirectly through innovation performance. However, human capital could not play the antecedent role to corporate sustainable longevity directly or even indirectly through innovation performance. Human capital indicators require deeper exposure in the context of small industries.

The development of operational performance indicators is of utmost importance for nuclear power plants, since they measure, track, and trend plant operation. Leading indicators are ideal for reducing the likelihood of consequential events. This paper describes the operational data analysis of the information contained in the Corrective Action Program. The methodology considers human error and organizational factors because of their large contribution to consequential events. The results include a tool developed from the data to be used for the identification, prediction, and reduction of the likelihood of significant consequential events. This tool is based on the resilience curve that was built from the plant's operational data. The stress is described by the number of unresolved condition reports. The strain is represented by the number of preventive maintenance tasks and other periodic work activities (i.e., baseline activities), as well as, closing open corrective actions assigned to different departments to resolve the condition reports (i.e., corrective action workload). Beyond the identified resilience threshold, the stress exceeds the station's ability to operate successfully and there is an increased likelihood that a consequential event will occur. A performance indicator is proposed to reduce the likelihood of consequential events at nuclear power plants.

Purpose: Due to the rapid growth of e-commerce in Thailand, the operational excellence of distribution service providers has been elevated. Thus, this research investigated the key drivers of operational performance of e-commerce distributors in Thailand. The research contains key variables: the analytics capabilities of an organization, supply chain disruption orientation, innovation capability, and operational performance. Research design, data, and methodology: An online survey is administered to top managers and key personnel (N=425) employed for at least one year in Thailand's top five e-commerce distributors. The sampling methods were conducted using purposive sampling, quota sampling, and convenience sampling. Confirmatory Factor Analysis and Structural Equation Model were applied to analyze and confirm the model's goodness-of-fit and hypothesis testing. Results: The findings reveal that an organization's analytics capabilities significantly affect supply chain disruption orientation and supply chain resilience. Furthermore, operational performance is affected by supply chain disruption, supplier quality management, and innovation capability. Nevertheless, supply chain resilience and digital supply chain have no significant effect on operational performance. Conclusions: The results imply that supply chain digitalization could drive higher operational performance. Distribution businesses are encountering transformation and disruption, which should address the high level of a digital supply chain, innovation, and quality management to maximize their profit margin and delivery service quality.

Two types of responses to climate change exist. First is climate mitigation which includes efforts of reducing CO2 and GHG emissions. Second response is climate adaptation process which is establishing climate resilience in the supply chain. The two are inherently different since mitigation strategy focus on eliminating the source of climate change and is long term in nature but adaptation strategy is moderating the impact of potential or current climate change. In order to embed climate resilience in the supply chain, mitigation strategies and adaption strategies must be implemented simultaneously. Corporation's adaptation to climate change related natural disaster can be seen as a response that includes mitigation and adaptation strategies simultaneously. A comprehensive climate change resilience supply chain approach has to be developed. This paper illustrated guidelines and adaptation process framework businesses can utilize in order to build climate resilience. Screening process before the actual assessment of risk was introduced as well as the whole adaptation process of establishing information system and strengthening climate-related operational flexibility.

최근 발생하는 극한가뭄에 대비하고자 본 연구는 실제 운영에서 수자원 시설물의 가뭄 취약도 및 가뭄대책별 우선순위를 파악할 수 있는 가뭄대응력 지표로 S-day를 제안하였다. 여기서 가뭄대책이란 용수공급 조정, 시설간 연계운영, 비상용량 고려 등이 대표적이며, 각 댐별로 그 구성에 차이가 있다. 본 연구에서는 국내 15개 다목적댐 및 용수댐에 대하여 가뭄대응력을 산정하였으며, 그 결과 20년 빈도의 가뭄이 지속될 시 15개 댐 모두 전반적으로 용수공급 조정이라는 가뭄대책을 통해 안정적인 가뭄대응력을 보였다. 하지만 다른 대책에서는 2년 이상 지속되는 다년 가뭄을 대비하지 못하였으며, 횡성댐과 안동·임하댐은 100년 빈도 가뭄 발생 시 대부분의 대책에서 S-day가 1년을 넘기지 못하였다. 특히, 횡성댐, 안동·임하댐, 군위댐, 운문댐, 대청댐, 주암댐은 20년 빈도 가뭄 발생 시, 가뭄대책을 적용하지 않으면 1년 내로 정상적인 용수공급이 불가능할 것으로 나타났다. 이에 본 연구에서는 S-day를 통해 가뭄대책별 최적 공급 용량을 제안하고 대책별 가뭄단계에 따른 가동시기를 변경해 가뭄대응 효과를 평가하였다. 마지막으로 미래 사회·경제적 변동에 따른 수요변화를 반영하고자 현행 공급 계약량에 대해 10%씩 증감하여 전체 15개 댐의 가뭄대응력을 재평가하였다. 그 결과 공급계약량이 10% 감소할 경우, 대부분의 댐에서 용수공급 조정만으로도 심각한 가뭄에 대한 대비가 가능할 것으로 분석되었다.
