  • This study seeks to provide implications for domestic-related policies through exploratory analysis research to support AI-based policy decision-making. The following should be considered when establishing an AI-based decision-making model in Korea. First, we need to understand the impact that the use of AI will have on policy and the service sector. The positive and negative impacts of AI use need to be better understood, guided by a public value perspective, and take into account the existence of different levels of governance and interests across public policy and service sectors. Second, reliability is essential for implementing innovative AI systems. In most organizations today, comprehensive AI model frameworks to enable and operationalize trust, accountability, and transparency are often insufficient or absent, with limited access to effective guidance, key practices, or government regulations. Third, the AI system is accountable. The OECD AI Principles set out five value-based principles for responsible management of trustworthy AI: inclusive growth, sustainable development and wellbeing, human-centered values and fairness values and fairness, transparency and explainability, robustness, security and safety, and accountability. Based on this, we need to build an AI-based decision-making system in Korea, and efforts should be made to build a system that can support policies by reflecting this. The limiting factor of this study is that it is an exploratory study of existing research data, and we would like to suggest future research plans by collecting opinions from experts in related fields. The expected effect of this study is analytical research on artificial intelligence-based decision-making systems, which will contribute to policy establishment and research in related fields.

  • 최근의 항만개발은 종합 국제물류서비스의 집합체로서, 국제물류기능, 산업경쟁력 확보를 위한 종합산업기지화, 자체 물동량 창출을 위한 경제유발 종합기지화, 지역경제 활성화를 기할 수 있는 부가가치항만, 친수 공간 확보 및 문화 활동의 복합기능화 등을 기할 수 있는 형태로 이루어지고 있다. 즉 국제분업화 및 SCM체제의 확산은 국제물류의 급격한 발전을 가져왔지만, 이에 대응하기 위해서는 항만을 중심으로 무역활동의 플랫폼을 구축하고, 대규모 항만배후부지를 개발하여 국제물류기지화를 기하여야 하는 새로운 부가가치 창출 노력이 있어야한다. 이러한 측면에서 부산항 신항과 BJFEZ 연계발전 방안을 "주관적인 요인", "산업환경적인 요인", "정부정책적인 요인" 세 가지로 대분류하여 분석한 결과는 "주관적인 요인"이 4.11점, "산업환경적인 요인"이 3.92점, 그리고 "정부정책적인 요인"이 4.01점이었다. 따라서 부산항 신항 및 BJFEZ의 연계발전을 위한 가장 근본적인 요인은 부산항 신항 및 BJFEZ의 연계발전 모델 정립을 통한 경쟁력 확보, 집중화된 시장전략 및 친시장적인 능력, 신속한 고객욕구 충족 및 신뢰성 확보 등 주관적인 연계발전 요인으로, 산업환경적인 요인이나 정부정책적인 요인 보다 월등히 앞서는 평균평점을 기록하였다. 그 다음 순위는 산업환경적인 요인(3.92점) 보다 정부정책적인 요인(4.01)이 더 높은 점수를 기록하고 있는데, 이것은 항만 및 경제자유구역의 개발과 발전은 공공성과 인프라 성격이 큰 분야로서 국가정부의 정책적인 배려없이는 올바른 발전을 기약하기 힘들다는 것을 나타낸 것이다.

  • Purpose - With the growth of the duty free shop field and an increase in the executive interest in it, it becomes necessary to examine if PBZ (1988) SERVQUAL could be applied to duty free shop service reflecting on this increased interest and the importance of marketing strategy alternative managing multinational customers. Therefore, the present research focused on the comparison of Korean and Chinese consumers. We examined how service quality would affect relationship quality and customer loyalty. Research design, data, and methodology - Surveys were distributed to 235 Korean and 220 Chinese consumers who have visited a Korean duty free shop. We analyzed frequency analysis, mean difference analysis, and reliability analysis, exploratory factor analysis, confirmatory factor analysis, structural equation model analysis, and multi-group analysis. Results - First, perceived tangibles, responsiveness, empathy, assurance, price benefits, product diversity, and IT convenience of duty free shop service all appeared to be positive effect on customer satisfaction; at the same time, only tangibles, responsiveness, empathy, assurance, and price benefits positively affected customer trust. Secondly, customer satisfaction and trust that are the components of the relationship quality appeared to be positive effect on customer loyalty. Thirdly, customers' satisfaction was found to play a full mediating role effect among all of the service quality factors with customer loyalty; however, customer trust was found to have the mediating effects only with tangibles, empathy, assurance, and price benefits. Fourthly, we found a difference between how service quality influences relationship quality and how service quality influences customer loyalty as a function of different nationality. As a result, it appeared that price benefits and IT convenience affected customer satisfaction more among Koreans than among Chinese. Finally, it appeared that customer satisfaction and trust affected customer loyalty more among Chinese than among Koreans. Conclusions - The results of this study contribute to the theoretical knowledge, but also provide strategic alternatives to enhance differentiation, international competence of enterprises led by duty free shop and service quality improvement and customer loyalty of enterprises are drawn as a foundation for constructing international customer relationship in future global era.

  • The purpose of this study is to identify problems and suggest improvements of estimating procedures and item of fisheries supply-demand statistics served as a basis for the fisheries supply-demand policies. Korea Rural Economic Institute(KREI) and Ministry of Oceans and Fisheries(MOF) respectively publish the fisheries supply-demand statistics. But the reliability of data is low as the statistics of these two organizations are limited and show discrepancy in the numbers. It is therefore difficult to use them as the basic data for policies. Also, an accurate data aggregation is difficult due to following problems in the items of statistics. 1) Problems in estimating route sales and non-route sales of production, 2) adequacy of fishery product yield rate compared to raw material in the fisheries import/export sector, 3) selection of target companies for understand stocks and survey scope of fish species, 4) applying'0'to non-edible product demand etc. In order to develop the fisheries industry as a future growth industry, it is necessary to establish the accurate fisheries supply-demand policy as the instability of fisheries supply and demand is increasing. To do this, statistical reliability has to be improved. The improvements proposed in this study should be implemented considering urgency. First of all, an exhaustive analysis of stock statistics and conversion rates of raw material yield in the fisheries import/export sector should be conducted. In the medium term and the long term, transferring production statistics to MOF and surveys on the use demand of non-food product and the level of reduced and discarded seafood products should be carried out in consecutive order.

  • As economic profits and social influences of firms grow with economic development and their organizational expansion, consumers increasingly require firms to have their social responsibility. Because social responsibility strongly influences corporate reliability, consumers' intention to purchase, customer loyalty to the products and the recognition of an ethical firm have gained attention as a concept of strategical importance. The prosperity of society should be proceeded for the sustainable development of a firm and the necessity of social responsibility should be emphasized to achieve virtuous circle structure that promotes growth. Additionally, the social responsibility should be proceeded to form trust on a firm. It is very important to change the recognition of consumers to purchase products and increase the profit of a company. This study aims to analyze how social responsibility properties of firms (economic, ethical, discretionary, and legal aspects as low-level factors of social responsibility which Carroll (1979) defined) affect corporate reliability and purchase intention. The analysis found that consumers trust in firms are positively influenced by ethical responsibility (0.391), economic responsibility (0.293), legal responsibility (0.251), and discretionary responsibility (0.248). The relationship between sub-factor of social responsibility and purchase intention is not significantly influenced by other explanatory variables. Corporate trust exerts a direct influence on purchase Intention (0.456). The social responsibility of a firm didn't influence a direct purchase intention. It was found that it brought positive effect on the purchase intention in the course of forming trust. This study suggests that firms should make efforts to understand the relationship between corporate trust and purchase intention along with the characteristics of social responsibility that consumers recognize and improve management strategies for mutual complementary interests.

  • With rapid economic growth, the urban environment has created a problem of human physical and mental illness. In order to solve these problems, urban forests have emerged as a way to mitigate the environmental risks through improving the polluted environment of the city and improve the quality of life. As the urban forests have expanded, the school forests movement has also been taking an important place recently. The study focused on the performance of school forests by comparing the perceptions among teachers and students about their functions. The questionnaire was composed of 4 questions concerning human matters, 10 questions for space recognition, 4 questions for thermal environment, 2 questions for health promotion, and 20 total questions for composition of survey items. The reliability of the school forest function, number of tree planting areas and quantities, the harmony of the planting, and the satisfaction of the school forest were analyzed in the questionnaire conducted by the school members. Although it does not recognize school forests, it has a positive response to the green space that is built outdoors. It is considered that outdoor education and environmental education are sufficient in school forests and green spaces. The results showed that the outdoor green space was more satisfactory when compared with the general school. Teachers and students' preferences were similar to 'seasonal changes' and' trees of various colors and shapes'. The reliability analysis between each item shows that the coefficient for cronbach's ${\alpha}$ was .700 to .834. The purpose of this study is to identify the perception of forest function among school forest members and to utilize them as a basic data in the future.

  • 폭발적으로 증가하는 데이터와 급변하는 기술적 발전은 과거와 현재를 넘어 미래를 예견하고 대응할 수 있는 새로운 분석 패러다임을 요구한다. 지시적 분석은 목표를 설정하고 이를 달성하기 전략을 수립함으로써 분석 결과의 제시에 그치는 게 아니라 사용자에게 목표 달성을 위한 구체적 행동과 그 결과를 요구한다는 점에서 기존의 기술적 분석, 예측적 분석과 근본적인 차이점을 보여준다. 그렇지만, 아직까지 구체적인 구현 방안이 널리 연구되고 있지 않고 있다. 본 연구에서는 연구 역량 강화를 목적으로 개발되고 있는 InSciTe Advisory 사례를 통해 고려할 사항과 어떤 개발 요소들이 필요한 지를 살펴봄으로써 해당 연구 분야의 기반을 제시하고자 한다. InSciTe Advisory 시스템은 5W1H 방법론을 중심으로 연구자가 롤 모델 그룹에 도달하기 위한 전략을 수립할 수 있음을 보이며, 평가 모델을 통해 Elsevier SciVal과 비교하여 126.5%라는 비교 우위적 평가 결과를 얻었다.
