  • This study aimed to evaluate the R&D efficiency of Daejeon Metropolitan City's regional industries and to derive policy implications for enhancing the competitiveness of regional industries. To achieve this, Data Envelopment Analysis (DEA) and Malmquist Productivity Index (MPI) were employed to analyze the efficiency and productivity changes of 16 Decision-Making Units (DMUs) in Daejeon's key industries from 2013 to 2022. The DEA analysis revealed that certain industry groups, such as the Research Industry (2013-2014), Bio Industry (2013-2014), and Metal Industry (2015-2017), demonstrated high efficiency by optimizing resource utilization. These industries were found to effectively maximize outputs by efficiently using resources in their R&D activities. On the other hand, some industries, such as the Knowledge Industry (2013-2014) and Wireless Communication Industry (2015-2017), recorded relatively low efficiency, indicating the need for improvements in resource utilization and operational strategies. The Scale Efficiency (SE) analysis showed that some industries were not operating at an optimal scale. Furthermore, the MPI analysis, which evaluated productivity changes over time, confirmed that technological progress and changes in technical efficiency significantly impacted industry-specific productivity. Efficiency changes over time were recorded as 70.96% (13-'14), 70.317% (15-'17), 68.59% (18-'20), and 76.57% ('21-'22), with a 28.38% improvement potential over ten years.

  • The food truck business, which involves selling various types of food from mobile vehicles, has gained significant popularity in urban centers and at events. These food trucks have rapidly expanded due to their relatively low initial investment and high flexibility, attracting customers with unique menus and personalized services. However, as competition increases, the need to manage service quality to boost customer satisfaction and encourage repeat visits has become more critical. Despite this growing importance, there has been limited empirical research on the topic. This study aims to analyze customer experiences with food truck services to gain strategic insights for improving service quality. By applying structural topic modeling to customer review data, the study identified 50 key topics. The process included a comprehensive evaluation of model diagnostics and interpretability to determine the optimal number of topics, ultimately selecting the most relevant ones related to service experiences. The impact of these identified topics on overall customer satisfaction was empirically tested using regression analysis. The results showed that aspects such as "Food Taste," "Friendly Staff," and "Positive Emotion" had a positive influence on customer satisfaction, whereas "Delayed Service," "Negative Emotion," and "Beverage Service" had a negative impact. Based on this analysis, the study proposes concrete methods for food truck operators to systematically analyze customer feedback and use it to drive service improvements and innovation. This research highlights the importance of data-driven decision-making in small business environments like food trucks and contributes to expanding the application of topic modeling in the service industry.

  • This study analyzed the determinants of employment of regular workers by firm size by merging statistical office survey(2006~2015), The results are as follows. First, as a result of the panel regression analysis, the labor income distribution, operating profit, sales, and R & D variables significantly increase employment, while the outsourcing cost, wage, capital intensity, and temporary employment decrease. However, wage variables of firms with minimum wage did not have a significant effect. Second, as a result of estimating the determinants of employment for regular workers by firm size, the variables of labor income distribution as a key variable had a significant positive impact only on SMEs, and the outsourcing cost ratio had a significant negative impact on both SMEs and large corporations. Third, as a result of estimating employment decision factors of SMEs and large enterprises by industry classification, both labor share(+) and outsourcing expense(-) are significant only in manufacturing industry, The higher the distribution ratio, the higher the employment rate, and the higher the cost of outsourcing, the lower the employment of regular workers. Employment impacts were greater for both SMEs. Therefore, it is necessary to strengthen policies on labor income distribution, operating profit, sales, R & D investment, etc., which are analyzed as having a positive influence in order to constantly employ regular job positions at the enterprise level. As the impact on employment varies depending on the size of industry and type of industry, it is necessary to adopt a job policy for each characteristic.

  • As domestic construction investment has been gradually reduced, the issue of expanding overseas CM market has increased. Strengthening CM capability from the view point of project life-cycle is required in overseas CM market. However, current regulations institutionally force public CM services to focus on the construction phase. Therefore, Korean CM firms can hardly have the opportunities for accumulating technical competitiveness especially for pre-construction phase. Result of this study shows that the total efforts in terms of man-hours for the construction phase is found to be more than 78 percent in domestic public CM projects. In this context, this study proposes the policies and tasks for improving 'rigid man-hour placement', 'unreasonable CM fee standards', 'CM firm selection method', 'unreasonable business scope decision', and 'evaluation of owner's project management capability' in order to improve domestic CM Industry as well as to expand overseas CM market successfully.

  • The role and importance of VE have been enlarged since VE application was mandatory by law in public sector in March, 2000. Public organizations have widened the technological horizon through VE competitions and applied VE technique to private investment projects. Many studies have been carried out on function analysis and VE procedure. In practice it is common that clients make a decision one-sidedly on whether or not VE proposals are selected. The VE procedure itself is not smooth. This study gives some suggestions on VE appraisal procedure and criteria at the last phase on VE process in order to smooth the progress of VE. The results of this study can be used as a tool to improve efficiency in the management of VE.

  • Korean government has initiated integrated-energy business (IEB) in Mokdong for energy conservation in 1983. Since then, IEB has been steadily expanding. This paper attempts to apply input-output(I-O) analysis to examine the economic effects of IEB. A static I-O framework is employed, focusing on three topics in its application: the impact of the investment of IEB on the production of other sectors and the inter-industry linkage effect; supply shortage effects of the IEB ; and the impact of the rise in IEB rate on prices of other products. The paper pays closer attention to IEB sector by taking the sector as exogenous and then investigating its economic impacts. The results can be widely utilized in decision-making about IEB policy.
