It is well-known that coordination within a supply chain reduces an inefficiency due to double marginalization in a decentralized chain. We study the effect of coordination in a three-tier supply chain consisting of a supplier, a manufacturer, and a retailer. A manufacturer invests in quality improvement. In this supply chain, coordination may occur between a supplier and a manufacturer (upstream coordination), or between a manufacturer and a retailer (downstream coordination). Using differential games approach, we characterize the equilibrium strategies and profits in three models, i.e., a decentralized supply chain, upstream coordination, and downstream coordination, for a finite planning horizon. We show that, although either type of coordination improves supply chain efficiency, upstream coordination and downstream coordination have different impacts on the equilibrium pricing and quality strategies and the consequent profits.

We examine the relationship between supplier involvement, inter-firm communication and product development performance when suppliers participate in product development projects. We investigate whether the relationship differs depending on two factors, (1) knowledge distribution and (2) relational norm between a manufacturer and a supplier. Based on in-depth study of seven cases, we find that both factors significantly influence the relationship, but in a different way. First, supplier involvement and inter-firmcommunication improve project performance when they fit with knowledge distribution between organizations. Specifically, supplier involvement should be aligned with how knowledge related to product development is distributed in organizations. Inter-firm communication becomes more critical when knowledge is evenly distributed to both organizations. Second, relational norm provides a foundation and a safeguard for effective interfirm coordination in product development projects. Relational norm improves project performance not only directly but also indirectly through improving the level of fit between knowledge distribution and supplier involvement/inter-firm communication.
외부 정보 탐색 전략이 혁신 성과에 미치는 영향에 대한 연구: 한국 중소기업을 대상으로

본 연구는 중소기업의 외부 정보 탐색전략이 기업의 혁신성과에 미치는 영향에 대해 파악하는 것을 목적으로 한다. 한국의 중소기업 3,398개를 대상으로 실증분석을 수행한 결과, 깊이 추구의 탐색전략과 범위 추구의 탐색전략은 상호 대체적 관계를 가지며, 이러한 대체적 관계는 기업이 협업경험을 보유할 때 약화되는 것으로 나타났다. 또한 두 유형의 탐색전략은 모두 기업의 혁신성과를 향상시켜 주지만, 깊이 추구 탐색전략이 범위 추구 탐색전략보다 상대적으로 더 큰 양의 영향을 미치는 것으로 나타났다. 그리고 범위 추구의 탐색전략을 실행하는 기업이 공식적인 정보보호방안을 채택할 경우 탐색전략의 혁신성과에 대한 효과가 약화되는 것으로 나타났다.

Purpose : This study aims to analyze and summarize the trends of research conducted on domestic elderly nursing simulation through a thematic literature review method, in order to gain insights into the overall direction of research in this field. Method : This study conducts a thematic literature review of papers published in domestic academic journals, focusing on topics related to domestic elderly nursing simulation, to understand the research trends in this area. Results : The analysis of research topics revealed the following themes addressed in the papers related to domestic elderly nursing simulation: ‘Development and validation of a simulation-based educational program aimed at enhancing patient safety performance for caregivers in elderly care facilities’, ‘Effectiveness of simulation-based education in preventing frailty among the elderly through home nursing interventions’, ‘Impact of simulation-based practical training programs on home health management knowledge, problem- solving skills, and clinical performance’, ‘Development and effectiveness of standardized patient simulation- based professional training programs for managing home care for seniors with dementia’, ‘Nursing students’ experiences in virtual simulation and hybrid simulation-based elderly nursing practicum education: a mixed-methods research approach’, ‘Effects of simulation-based education on communication skills, academic self-efficacy, and attitudes towards the elderly among nursing students when caring for elderly individuals with cognitive impairment’, and ‘Assessment of demand for simulation-based home nursing education for frail elderly individuals’. Conclusion : These findings underscore the diverse applications and effectiveness of simulation- based education in various aspects of elderly nursing care in domestic settings.
서울 소재 한 병원의 코로나바이러스감염증 19 환자를 돌보는 간호사의 극복 경험
김묘연(Myo Youn Kim),김성신(Seong Shin Kim),심정은(Jeong Eun Sim) 한국간호연구학회 2023 한국간호연구학회지 Vol.7 No.1
Purpose : The purpose of this study is to explore the essential structure and meaning of the in-depth experience of nurses caring for COVID-19 patients, and to provide basic data for preparing a holistic response strategy in the event of a new infectious disease in the future. Methods : This is a qualitative study conducted using in-depth interviews with 10 nurses in charge of COVID-19 patients and analyzed using the Colaizzi analysis method(1978). Results : As a result of the study, 158 meaningful statements, 4 topic groups, and 11 topics were derived about the experiences of nurses caring for COVID-19 patients. The subjects discovered that the experiences of nurses caring for critically ill patients in unfamiliar environments, such as COVID-19 isolation wards and environments with insufficient response guidelines, were a new dimension that was different from nursing patients with infectious diseases in the existing nursing environment. Conclusion : This study looked at the role of nurses who were pivotal in overcoming the epidemic of new infectious diseases by exploring the experiences of front-line nurses in crisis situations of emerging infectious diseases, and analyzed and structured their experiences as a whole.
