This study sought to examine the sustainability criteria found in the global sourcing practices of global fashion retailers. Sustainable supply chain management, with a particular focus on the sustainability criteria of global sourcing, was analyzed. This qualitative study was based on a focus group interview and corporate social responsibility (CSR) annual reports. Eight master categories, 18 middle categories, and 37 bottom categories were extracted. The key categories and their middle categories were as follows: (1) Social compliance (working conditions, employment, safety); (2) Environment concerns (environmental pollution management, eco-friendly production, supply chain environment); (3) Energy efficiency (energy saving program, store environment); (4) Consumer protection (restricted substances management, consumer product safety improvement); (5) Management system (code of conduct, triangle audit system); (6) Community social activities (local community service, voluntary activities, charitable activities); (7) External stakeholder engagement (media & non-governmental organization management, maintenance of relationship with local authority); (8) Brand protection (respect for companies' intellectual property). The findings of this study offer academically significant insights into the sustainability criteria that can be encountered by companies under diverse global sourcing scenarios, revealing that global sourcing by fashion retailers is not merely a means of reducing costs, but a way of generating new jobs and making a social contribution to developing countries. The study's findings also have practical significance, offering guidelines for general CSR activities in the global sourcing process.

전 세계적으로 기후변화에 대응하기 위하여 탈탄소화의 중요성이 강조되고 있으며, '2050 탄소중립'이 글로벌 의제로 부상하였다. 국내 항만공사는 우리나라 정부의 탄소중립 추진과제에 맞추어 세계적인 탄소중립 규제 흐름에 동참하고 있다. 항만에서 탈탄소화가 중요하게 인식되기 시작하면서, 2010년대 이후로 유해산출물을 고려한 컨테이너터미널 효율성 분석이 다양하게 진행되고 있다, 하지만, 이산화탄소 배출량을 고려하여 국내 컨테이너터미널의 효율성을 비교분석한 연구는 부족한 실정이다. 그리고 대부분의 선행연구는 IPCC 가이드라인에서 제시하고 있는 Tier 1 기준에 따라 이산화탄소 배출량을 측정하였으며, Tier 3 기준에 따라 효율성을 분석한 연구는 전무한 상황이다. 이에 본 연구에서는 17개 국내 컨테이너터미널 운영사를 대상으로 Tier 3 방식 기준 이산화탄소 배출량 지표를 활용하여 효율성을 분석하였다. 그리고 DEA-SBM 모형과 Undesirable Outputs 모형 분석결과를 비교하여 유해산출물 고려 전후의 효율성 변화를 파악하였다.

Recently, the fierce competitions in the shipping industry and the global economic downturn have heavily influenced ports' operational strategies. In order for port authorities to remain competitive at an international level and to provide more accurate information to develop National policies, ports are required to analyse and improve operations' efficiency. In this paper, the efficiency of 19 Italian ports in 2013, handling different types of cargoes, is assessed through the application of Data Envelopment Analysis (DEA), with constant return to scale (CRS) and variable return to scale (VRS). The purpose of this study is to analyze the efficiency of Italian ports and evaluate whether differences in size and specialization of each port (or cargo handled) are directly correlated with ports' efficiency.

Background & Methods: The purpose of this research is to estimate the efficiency of the pharmaceutical firms and the determinants of their efficiency. Stochastic frontier analysis(SFA) and panel study are applied to the data of 60 domestic pharmaceutical firms from 2006 to 2012. Results & Conclusion: First, the result of the stochastic frontier analysis shows that overall efficiency of the pharmaceutical firms is increasing as time goes by. However, if firms are classified by the scale, the larger firms show more efficiency and if classified by the degree of innovativeness, the innovative firms show more efficiency compared to the non-innovative firms. This evidences show that the scale and R&D investment have significant relationships with the efficiency of the pharmaceutical firms. Therefore, it is necessary to increase the national level of investment for the fundamental researches to vitalize R&D of the new drugs. Second, the result of estimation of the determinants of efficiency shows that the firms with larger sales promotion expenses and entertainment expenses have less efficiency compared to the other firms. This can be explained by the structural characteristics of the small generic pharmaceutical firms. Therefore, the government had better make the pharmaceutical firms to reduce sales promotion and entertainment expenses and increase R&D expenses by introducing systems such as global budgeting system on medicine or reference pricing system.

Purpose: This study aims to delve into the empirical implications in management efficiency by analyzing the relation between management efficiency and debt ratio in public institutions. Methods: Based on 165 public institutions published in public business information system from 2016 to 2020, Data Envelopment Analysis(DEA) for estimating management efficiency was performed. This study analyzed the relationship between management efficiency and debt ratio using multi-regression analysis. It also examines how the relationship varies depending on the type of public institution. Results: The results of this study are as follows; We find that there is no significant relation between management efficiency and debt ratio. However, we find that this relationship can be different depending on the type of public institution. Management efficiency is negatively associated with debt ratio for quasi-market type public institutions. This negative relation tends to mitigate for market type public institutions, which suggests that management efficiency may convey differential implications depending on the type of business environment represented by the type of institution. Conclusion: The overall results suggest that the government needs to due caution in establishing a policy plan to reduce debt by increasing management efficiency, taking the specific business environment, particularly with regard the type of institution.

As an exploratory attempt, this study examines the patterns of global R&D activities of industrial firms, focusing on the management of overseas R&D centers in terms of their location, primary missions, management style, organizational structure and communication and global human resource management system Based on a review of existing studies mainly undertaken in advanced countries and cases of foreign MNCs, several hypothetical relationships are postulated : 1) There appears a strong relationship between the purpose and location of R&D activities : 2) Different levels of global management and technological capability lead to different types of overseas R&D organizations : 3) The relationship between autonomy of overseas R&D organizations and their R&D performance will be moderated by organization size, development time pressure, and a need for internal efficiency : 4) Frequent communication between the headquarter and overseas R&D organizations will increase R&D performance 5) Mutual exchange of R&D professionals between the headquarter and overseas R&D organizations will be positively related with R&B performance. In addiction, this study explores the current state of global R&D activities of selective firms in Korea, based on ie-depth interviews, and analyzes the sources of problems in their global R&D management. Finally, theoretical and managerial implications of this study are discussed and future research directions are proposed.

Cold-formed steel (CFS) sections are thin-walled, therefore, more susceptible to different types of geometric imperfections. Global type of geometric imperfections has a significant impact on the load-carrying capacity of flexural members. This paper reports an experimental study that discusses the influence of global imperfections on the flexural response of CFS built-up I-beams composed of two lipped channels, with simply supported ends, under four-point loading. Global imperfections of magnitude over eight times the maximum permissible ones were induced in the specimens, leading to their distress. Using various simple stiffening schemes, the capacity and stiffness of the distressed specimens were improvised. The performance comparisons were made based on the maximum loads resisted, flexural stiffnesses offered, and failure modes experienced by the specimens. As experimental data on such distressed specimens are currently lacking in the literature, the test results of the present study will provide the necessary data needed by future researchers to numerically extend this study further, which will help in the development of necessary design guidelines for the same. The stiffening schemes significantly improved the structural efficiency of distressed specimens in terms of strength and stiffness, by over 60%. As a result, an effective and time-saving solution to such realistic structural engineering problems is given.
