In the evolving global food industry, international certifications have become essential for seafood export companies to ensure product safety, quality, and sustainability, as well as to meet consumer demands and regulatory standards. This study analyzes the decision-making factors influencing the acquisition and maintenance of international certifications among Korean seafood export companies, using decision tree analysis. The research surveyed 134 seafood export companies, focusing on six key factors: corporate characteristics, environmental factors, input factors, organizational structure, company capabilities, and external relationships. The decision tree analysis revealed that among corporate characteristics, the size of sales revenue, number of employees, and proportion of exports were found to play significant roles. For environmental factors, specific demands from overseas buyers, shifting consumer preferences, and compliance with global standards were identified as having a major impact. Regarding input factors, certification costs, validity periods, and investments in processing facilities were revealed to be critical variables. Organizational factors such as managerial support and dedicated personnel, capability factors like inter-departmental collaboration and processing system capacity, and relationship factors including partnerships with certification and export support agencies were also critical in the certification process. This study identified various factors influencing the decision-making process for acquiring and maintaining international certifications among Korean seafood export companies and analyzed the importance of detailed variables for the first time. Additionally, it provides practical and policy-oriented implications to promote the adoption of international certifications as part of efforts to enhance the global competitiveness of Korean seafood. Furthermore, this study contributes to the academic understanding of the decision-making process related to international certifications in seafood export companies.

PURPOSES : The purpose of this study is to propose the certification process of International Roughness Index measuring device, i.e., a method for evaluating riding quality on road surfaces. METHODS : ROMDAS was selected as a reference device for verifying the accuracy of the IRI measuring device and the reliability of ROMDAS was checked through leveling in the laboratory and outdoors. To verify four different IRI measuring devices in Korea, the proper field test section was selected and IRI evaluation was conducted. A distance measuring instrument (DMI) - for verifying the accuracy of mileage - and IRI (as an index of roughness) were selected as the main evaluation parameters. For DMI verification, five repeated experiments were conducted for a 1 km section and, for IRI verification, speed variables of 40 km/h, 60 km/h, and 80 km/h were selected. Each device was tested at each speed 10 times. The accuracy of the measurement device was analyzed by comparing the measurement results with the verification criteria. RESULTS : As a result of the comparative experiment between the leveling and ROMDAS devices, the deviation of each measurement point value was within 1 mm and the R2 value was 0.8, demonstrating an excellent correlation. As a result of DMI verification, the tolerance of the three devices was found to be within 0.1 %; however, one device had a tolerance of 0.8 %, indicating that correction was necessary. For IRI evaluation, the average IRI value of the two reference devices was 2.02 m/km and the Minnesota standard was used as an analysis criterion. After the test, only one of the four devices was found to be effective across all speed ranges. Therefore, it was determined that additional sensor calibration is required to improve accuracy. CONCLUSIONS : In this study, the IRI device accuracy was evaluated through field tests. Hence, a new certification process for the IRI test device was proposed via four steps. To improve the accuracy of the IRI measurement, it is necessary to periodically verify the device. If this proposed certification process is applied, the accuracy of the IRI devices can be improved.

This study analyzes the certification system and international standard trend for cold storage and proposes evaluation method for the development of KS in accordance with international standards so that high quality products can be supplied to consumers. The international standard for cold storage can be divided into three categories: refrigerator unit, refrigerator warehouse, and cold chain. Each similar standard was analyzed and studied. Among them, AHRI's international standard is the most advanced standard, so test methods and conditions are matched. Finally, the performance evaluation technology and the performance evaluation technology for the refrigerator unit suitable for the domestic situation using the analyzed method were proposed.

현재 전세계는 재난으로 인한 국가 경제ㆍ사회전반에 막대한 영향을 미치고 있어 인증을 통하여 문화 확산과 더불어 표준 도입으로 재난의 선진관리체계의 확립이 요구되고 있다. 우리나라뿐만 아니라 국외에서도 방재관련 인증제도는 방재기술지정, 방재신기술검증 등 범용적이지 못하여 한계가 있으며, 일부하고 있는 방재기술에 대한 성능인증 범위를 현재의 기술인증에 국한하고 있고, 시스템 인증은 하고 있지 않고 있어, 이를 확대하여 국제적 흐름에 선제적 대응 필요성이 있다. 그러나 현재까지 우리나라는 방재기술은 주로 자연재해에 관련된 분야로 독자적 영역에서 관련기술들이 발전해 왔음. 최근의 동향을 보면 다양한 분야의 복합적 기술들의 융합을 통한 기술이 개발되고 있다. 따라서 국제표준화에 목표를 두고 개발하여 세계 시장을 리드하는 방재기술의 중심국가로 도약 하는 기술적 우위가 필요하다. 그러기위해선 국내의 방재기술인증 실태와 국외의 선진국에서 실행되고 있는 인증에 대한 비교분석을 통하여 한국형 방재기술성능 인증 기술개발에 따른 발판을 마련하여 국제표준화 토대를 마련하고 방재기술 성능인증 세부기준에 따른 방재관리의 표준화로 시너지효과를 도출하고자한다.
