DonHee Lee 한국인터넷전자상거래학회 2016 인터넷전자상거래연구 Vol.16 No.2

This study used data envelopment analysis(DEA) to study the operational efficiency of the Korean healthcare system during the period from 2000 to 2013. We selected two output variables, life expectancy at birth and the infant mortality rate, and five input variables: number of physicians and nurses, number of hospital beds, MRI units, and total health expenditure as a percentage of GDP. The use of the DEA method enabled us to evaluate how Korean healthcare systems could improve their technical and scale efficiency on an operational level based on the results we obtained for the period 2000 –2013. The results indicate that, as time passes, Korean healthcare systems are becoming marginally inefficient even though inputs are increasing. This study contributes to the practice of healthcare management and could theoretically improve operational efficiency in the healthcare industry based on the compared efficiency of Korean healthcare systems.

Lee DonHee(이돈희) 한국산업정보학회 2018 한국산업정보학회논문지 Vol.23 No.3

This study examines the impact of severe weather on lean supply chains. First, this paper reviewed the literature on the disruptions and damages that severe weather events cause on supply chain. Then, several recent examples of lean supply chain disruptions due to severe weather were discussed. The results of the study indicated that the frequency of weather related disasters is increasing and extreme weather events will increase potential risks to supply chains. First, building organizational resilience will help firms look beyond efficiency and profits in managing lean supply chains. Second, the concept of sole sourcing may need rethinking to maintain a supply chain that is lean and resilient. Third, organizations must plan ahead for supply chains in unpredictable weather. Fifth, communication is a key for anticipating and avoiding the impact of severe weather. This study proposes of a set of strategies, both theoretical and practical, that business firms should develop to effectively prevent and respond to severe weather related disruptions in lean supply chains.

( Donhee Lee ),( Kyoungro Yoon ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.10

Recent research into wireless sensor network (WSN)-related technology that senses various data has recognized the need for spatio-temporal queries for searching necessary data from wireless sensor nodes. Answers to the queries are transmitted from sensor nodes, and for the efficient transmission of the sensed data to the application server, research on index processing methods that increase accuracy while reducing the energy consumption in the node and minimizing query delays has been conducted extensively. Previous research has emphasized the importance of accuracy and energy efficiency of the sensor node's routing process. In this study, we propose an itinerary-based R-tree (IR-tree) to solve the existing problems of spatial query processing methods such as efficient processing and expansion of the query to the spatio-temporal domain.

사회적 자본이 CSR 이행의지와 지속가능 SCM 성과에 미치는 영향

이돈희(DonHee Lee) 대한경영학회 2016 大韓經營學會誌 Vol.29 No.1

본 연구는 공급자 관점에서 관계적 자본과 CSR 이행의지가 지속가능 SCM 성과에 미치는 영향 정도를 분석하고자 연구모형을 제시하였다. 또한 파트너십의 정도에 따라 파트너십이 높은 집단과 낮은 집단으로 구분하여 조절효과를 분석하였다. 본 연구모형의 가설검증을 위해 국내 원청기업 및 1․2․3차 협력업체 구매/물류/자재담당 관리자를 중심으로 자료 수집을 하였으며, 304개 응답 자료를 본 연구 분석에 사용하였다. 분석결과 관계적 자본은 CSR 이행의지에 정(+)의 영향을 미치고, CSR의 경제적 · 윤리적 · 법률적 책임이행의지는 지속가능 SCM 성과에 정(+)의 영향을 미치는 것으로 나타났다. 그러나 CSR의 윤리적 책임이행의지는 지속가능 SCM 성과의 환경적 성과에 통계적으로 유의하지 않은 것으로 분석되었다. 조절효과 분석결과, 파트너십의 정도에 따라 CSR 이행의지와 지속가능 SCM 성과와의 관계에는 차이가 있는 것으로 분석되었다. 즉, 협력업체와의 정보공유, 협업 수준 등은 협력업체의 역량에 따라 다르게 적용될 수 있기 때문에 CSR 이행의지는 파트너십의 정도에 따라 지속가능 SCM 성과 향상에 차이가 있는 것으로 분석되었다. 본 연구결과를 종합적으로 살펴볼 때, 기업이 경쟁력을 확보하기 위해서는 사회적 구조 내에서 기업간 협력을 통해 경제생태계를 보호하고 같이 공존할 때 기업의 경쟁력을 확보할 수 있다. 또한 경제생태계 구성원들의 이해관계를 존중하고 기업은 사회구성원들에게 신뢰를 구축해야 만 생존할 수 있다. 본 연구는 다음과 같은 학문적 시사점을 제공한다. 사회적 자본 구축은 CSR 이행을 위한 전제조건으로 외형적인 사회적 책임 이행보다는 이행을 증진 실천할 수 있는 생태계를 구축해야 된다. 지속가능 SCM을 통하여 기업은 협력업체 간 신뢰구축 및 상호협력, 가치 창출, 윤리적 경영 등 CSR 이행을 위한 실질적이고 실천 가능한 전략적 방안을 강구해야 된다. 또한 지속가능 SCM 내에서의 기업 간 실천적 전략방안을 기업의 특성에 맞게 도출하여 협력기업 간 상생할 수 있기를 기대한다. Many factors (economic, ethical and legal) impact a firm’s commitment willingness to undertake Corporate Social Responsibility (CSR). CSR in the field of supply chain management (SCM) are commonplace, but their measured success does not frequently appear in the literature. The complexity of potential relationships in supply chain organizations has made researching connections between CSR and sustainable supply chains difficult. As the process of SCM flows through inter-firm cooperation, building partnerships within the supply chain is a critical factor for CSR and organizational performance. A firm’s CSR may drive to economic, environmental, and social achievements that improve the firm’s organizational performance by reducing total costs, improving quality, and enhancing corporate image with customer satisfaction. Further, understanding of social capital is necessary to create strategic plans for sustainable SCM. As social capital can promote positive CSR willingness through partners, the improvement of sustainable SCM performance with regard to CSR importance should differ based on the type of partnerships established. The purpose of this study is to examine the relevance of interrelationships among social capital, CSR commitment, and sustainable SCM. The research model is proposed that describes the influence of social capital accumulation in SCM on sustainable SCM performance through CSR commitment and partnership. This paper assumed that social capital accumulation affects CSR commitment and sustainable SCM performance. In addition, CSR commitment would differently affect sustainable SCM performance in accordance with the various types of partnerships. The hypotheses were tested using structural equation modeling with data collected from 304 companies. The results of the study support that the relational dimension of social capital is positively associated with CSR commitment. Also, economic, ethical, and legal responsibility commitment of CSR are positively associated with constructs of sustainable SCM performance. However, ethical responsibility commitment of CSR is not related to environmental performance of sustainable SCM. Results show the moderating effect of partnership influence the relationships between CSR commitment and sustainable SCM performance. The results of the study suggested that the relational dimension of social capital is a prerequisite for CSR commitment, which is the foundation for sustainable SCM performance. Also, the degree of information sharing and collaboration with vendors may vary according to vendor competencies. Thus, improvement in sustainable performance of SCM with regard to CSR commitment may differ according to the degree of partnerships with other organizations. The contribution of this study to social capital accumulation as a prerequisite to CSR commitment for sustainable SCM performance was discussed. As social capital accumulation provides cultural and economic grounds for sustainability, cooperation becomes imperative for nurturing a sustainable business. As importance of partnerships to CSR commitment and sustainable performance of SCM, building long-term trust, share information, and determine the scope or type of cooperation with vendors. Therefore, through sustainable SCM firms can devise substantial and practical strategic plans for CSR commitment such as building trust among vendors, cooperation or collaboration, value creation, and ethics management.

이돈희(DonHee Lee),이동현(Dong Hyun Lee) 한국산업정보학회 2021 한국산업정보학회논문지 Vol.26 No.4

본 연구는 COVID-19과 같이 불확실성이 증대되어 있는 상황에서 인지된 불확실성, 거래특성, 공급업체 역량과 공급망 성과 간의 상호 관계를 문헌 연구를 바탕으로 제시하였다. 이론 고찰 결과 거래특성 및 공급업체 역량은 인지된 불확실성에 영향을 미치며, 인지된 불확실성은 공급망 성과에 영향을 미치는 매개 변수가 될 수 있음을 확인하였다. 이러한 연구결과는 현재와 같은 팬데믹 상황이 공급망의 성과에 미치는 영향을 돌이켜보고, 동일한 환경 하에서 불확실성을 상대적으로 낮추기 위한 방법을 본 연구에서 제시한 연구모형과 이론적 고찰을 바탕으로 살펴볼 수 있다는 점에서 의미가 있다 하겠다. This study explores the relationship among perceived uncertainty, transaction characteristics, supplier capability, and supply chain performance through theoretical review in the context of increasing uncertainty such as COVID-19 in the supply chain. Based on comprehensive literature review, it was concluded that transaction characteristics and supplier capability affect perceived uncertainty, and supply chain performance can be affected by perceived uncertainty. These findings are meaningful in that we can estimate how to reduce uncertainty of the supply chain under the same pandemic situation.
