이창준,김수효 한국유통과학회 2024 유통과학연구 Vol.22 No.1
Purpose: This study sheds light on the need for trust in buyer–seller relationships in supply chains and explores why long-term orientation is important. It also investigates the effect on relationship performance. This study provides implication on how to build robust supply chains. Methodology: A survey was conducted with firms with supply chains in South Korea. A total of 350 valid questionnaires were analyzed through Entrust Survey—a sampling company. Structural equation modeling (SPSS 18.0 and AMOS) was employed to test the hypotheses. Results: Cognitive trust had a positive effect on emotional trust. Emotional trust had a positive effect on long-term orientation but did not have a significant effect on relationship performance. Long-term orientation was proportionate to relationship performance. Conclusions: Trust is a critical factor in supply chains. As business environments are rapidly changing, the uncertainties are also meaningful. Supply chains have collapsed owing to COVID-19, the Russia–Ukraine war, and the U.S.–China trade war, and they are only just recently being rebuilt. Maintaining relationships with supply-chain partners is vital, and promoting cognitive and emotional trust is necessary.

프로보노 CSR(pro bono CSR) 수행 강도가 참여직원의 임파워먼트와 직무성과에 미치는 영향
김지혜,민순홍,김수효 한국윤리경영학회 2023 윤리경영연구 Vol.23 No.1
Corporate social responsibility (CSR), which primarily aims to share the economic surplus earned by a firm with stakeholders, is often suspended when the firm faces a weaker financial situation. However, the growing demand for CSR from regulatory bodies worldwide is forcing firms to develop more sustainable forms of CSR. Pro bono CSR is a company-sponsored activity in which employees offer free-of-charge services to stakeholders based on their job-related capabilities. Conducting pro bono CSR based on a company’s existing human resources is a cost-effective way to introduce sustainable CSR. Despite the obvious potential of pro bono CSR, existing CSR literature has not offered a theoretical explanation for how pro bono CSR can produce positive outcomes for a firm. To address this, the present study utilizes the job characteristic model and psychological empowerment theory to propose a theoretical model in which an increase in the intensity of pro bono CSR will lead to the empowerment of the participating employees in performing their jobs which, in turn, helps to enhance their job performance. Based on the survey data collected from employees at Korean financial institutions, this study empirically tested this hypothesis. The empirical results confirmed that (1) the intensity of pro bono CSR empowers the participants at work, (2) this empowerment enhances the participants’ job performance, and (3) this empowerment fully mediates the relationship between pro bono CSR and job performance. This study contributes to the body of knowledge by providing a theoretical basis for future research on pro bono CSR. The study also helps practitioners by offering a logical explanation of the benefits of pro bono CSR and suggesting that pro bono CSR programs must be designed to include job characteristics that promote empowerment at work. 기업의 경제적 잉여가치를 사회에 환원하는 것을 목적으로 하는 기업의 사회적 책임(corporate social responsibility, CSR)은 태생적으로 기업의 재무적 상황에 따라 지속 또는 중단되는 경우가 빈번하다. 점차 높아지고 있는 CSR 요구에 대응하기 위해 학계와 산업계는 지속 가능한 CSR 방안 마련에 고심해 왔다. 프로보노 CSR(pro bono CSR)은 기업이 구성원의 직무 관련 전문성을 활용해 CSR 활동을 전개하는 것이다. 기업은 이미 보유한 자원(주로 인적자원)에 기반해서 CSR을 실시함으로써 자원 투입을 최소화함은 물론 참여직원의 직무성과를 높일 수 있어서 지속 가능한 CSR 대안이 될 수 있다. 프로보노 CSR의 잠재적 비용 효과성에도 불구하고 기존 경영학 분야 CSR 연구 흐름에는 프로보노 CSR의 작동 메커니즘에 대한 이론 및 실증연구가 부족하다. 본 연구는 기존연구의 한계점을 극복하는 것을 목적으로 한다. 본 연구는 직원의 직무 관련 전문지식과 경험을 활용하여 수행하는 기업 주도 프로보노 CSR의 본질이 현업에서 수행하는 직무의 그것과 동일하다는 점에 주목하여, 직무특성모형과 임파워먼트 이론을 바탕으로 직원의 프로보노 CSR 수행 경험은 직원이 현업에 복귀했을 때 직무를 대하는 심리상태와 직무성과에 긍정적 영향을 미친다고 주장한다. 본 연구는 프로보노 CSR을 시행하고 있는 금융사에 근무하는 직원 중 프로보노 CSR 유경험자를 대상으로 수집한 자료를 활용해서 위계적 회귀분석을 실시해서 다음의 결과를 얻었다: (1) 프로보노 CSR 수행 강도는 참여직원이 현업에서 인지하는 임파워먼트를 유도하고, (2) 임파워먼트는 직무성과(직무성과, 직무만족, 조직몰입)를 높이며, (3) 임파워먼트는 프로보노 CSR과 직무성과 간 관계를 완전 매개한다. 본 연구는 연구자들에게 향후 프로보노 CSR 관련 실증연구를 위한 이론적 토대를 제공한다. 또한, 기업 인사・CSR 담당자들에게는 프로보노 CSR의 효익을 설명하고, 프로보노 CSR 실행을 통해 참여직원의 임파워먼트와 직무성과를 높이기 위해 고려할 사항을 제안한다.

Collaborative Communication, Information Sharing and Supply Chain Performance
Changjoon LEE,김수효 한국유통과학회 2021 The Journal of Industrial Distribution & Business( Vol.12 No.5
Purpose: This study empirically investigates the effect of collaborative communication and information sharing on the supply chain performance of South Korean pharmaceutical companies. Specifically, it understands the importance collaborative communication and suggests a method for investigating communication in academic research on the pharmaceutical industry. Investigating this sector is crucial because the importance of the pharmaceutical industry is increasing globally against the background of the Covid-19 pandemic. Research design, data, and methodology: A questionnaire was administered to employees of South Korean pharmaceutical companies and 244 valid responses were used for the statistical analysis. Additionally, structural equation modeling was used to measure the relationships between the observed and latent variables. Results: Collaborative communication has a positive effect on information sharing. However, information sharing, unlike collaborative communication, does not exhibit a significant positive relationship with supply chain performance. These results indicate that it is important to communicate effectively in the supply chain rather than strive for the right type of information sharing. Conclusions: Consumers and retailers within the supply chain should continue to strive for candid communication. This study is meaningful, as it empirically tests the relationships between collaborative communication, information sharing, and supply chain performance in the South Korean pharmaceutical industry.

Ceramic filter was prepared using cordierite powder and it was coated with $V_2O_5$ catalyst by vacuum impregnation method. The filter had the apparent porosity of 58 %, the compressive strength of 10 MPa and the pressure drop of 1200 Pa at the face velocity of 5 cm/see and 400$^{\circ}C$. $NO_x$ removal efficiency of only $V_2O_5$ coated on cordierite filter showed the removal efficiency of 80 %, and it was improved up to 90 % by increasing specific surface area of filter elements from the acid treatment. The high surface area is due to the removal of Mg and Al ions from the silicate structure and subsequent generation of free amorphous silicate on the surface of the cordierite. 코디어라이트를 원료로 하여 다공성 세라믹 필터를 제조하였고, 진공함침법으로 $V_2O_5$ 촉매를 코팅하였다. 제조된 세라믹 필터의 기공률은 58%, 압축강도는 10 MPa, 400$^{\circ}C$, 5 cm/sec의 유속에서 압력손실은 1,200 Pa이었다. $V_2O_5$ 촉매의 경우 $NO_x$에 대해 80% 이상의 처리효율을 나타내었고, 산처리에 의한 필터의 비표면적 증가를 통해 처리효율을 약 10%개선할 수 있었다. 이는 필터의 비표면적 증가를 통해 코팅된 촉매의 분산성을 향상시킴으로써 촉매의 활성점이 증대되었기 때문으로 판단된다.
