As engineering is required to answer directly and more heartily than before the requirement of society and markets, we want to answer the following questions. What kind of open innovation channels exist, and how can these channels operate as a knowledge funnel to conquer the growth limit of capitalism in the 4th industrial revolution? At first, we built up the concept model of open innovation engineering from a conceptual experiment and attempted to prove this model by literature reviews. Second, we applied this open innovation concept model at the papers of Society of Open Innovation: Technology, Market, and Complexity (SOI) 2019 Special Issues of Electronics as a preliminary study. Additional field researches on each open innovation engineering channel in addition to research on finding out more open innovation engineering channels are required.

Most global zinc firms consist of multiple refineries with various production capacities. However, it is known that efficiency and Bonus Zn are mostly dependent on a firm’s production capacity. Thus, it is important to examine whether there is knowledge transfer of efficiencies and Bonus Zn among refineries within the same company, even if their production capacities are quite different. The Data Envelopment Analysis (DEA) is used to measure efficiency scores of forty-two zinc refineries. To examine whether there is a knowledge transfer about efficiency and Bonus Zn within a firm, a propensity score model is newly applied. Additionally, a regression model is utilized to identify whether this propagation is more effective if refineries are in the same country. It is found that about 86% of the refineries are inefficient, which indicates that there is much room for refineries to improve their performance. From the result, it is identified that the knowledge of efficiency and Bonus Zn is transferred within the company. This transfer is particularly influential when both refineries are located in the same country. We also find that firm’s revenue can be maximized when efficiency is high and the production capacity and/or Bonus Zn are significant.

The purpose of this study is to verify the existence of congestion in Korean hospitals, to identify the causes of congestion, and to suggest directions for efficiency improvement of hospitals. The result showed that congestion occurred in 71.90% of 1185 hospitals. In addition, it was found that hospital specialization has a negative effect on congestion. In other words, the higher the hospital specialization, the lower the overall congestion rate of the hospital. More specifically, the specialization of hospitals also showed a negative effect on congestion of nurses. On the other hand, hospital specialization was found to have a positive effect on the congestion of the number of doctors, but it does not have a significant effect on the congestion of hospital beds. It was also found that hospital size has an effect on the relationship between hospital specialization and congestion, but the location of the hospital and the type of ownership did not act as a moderator.

Public R and D management agencies have been taking on key roles in the national R and D ecosystem. The purpose of this study is to suggest ways to improve the operational efficiency of public R and D management agencies based on analysis of their current status. We approached this study from a life-cycle perspective as it applies to the plan-management evaluation of R and D. Data-collection sources included documents, surveys, and interviews with staff members in agencies responsible for national R and D management. Based on the analysis results, we present suggestions for improvement in three areas: (a) unification of R and D planning and evaluation of individual ministries; (b) establishment of a panministerial management system for public R and D management agencies; (c) improvement and development of public R and D agencies’ expertise and management services. Finally, we discuss possible improvements and the limits of this study.

Non-ferrous metals are widely used as basic materials in various industrial fields, and zinc is a metal that is produced and used next to iron, aluminum, and copper. In this study, DEA (data envelopment analysis) was applied to measure the efficiency of 43 zinc smelters in three countries in East Asia: Korea, China, and Japan. The constant returns to scale (CRS) and the variable returns to scale (VRS) models, and the slack-based measure (SBM) were used for the analysis. As a result of the efficiency analysis, there were three efficient zinc smelters in the CRS model, 14 in the VRS model and 14 in the SBM. The average efficiency was 0.458 based on the SBM, which indicates that there is room for improvement in efficiency. In addition, the average scale efficiency value was 0.689, showing the scale to be inefficient. Therefore, it can be seen that the labor cost and the energy cost must be brought to an appropriate level. The Tobit regression analysis was used to analyze the causes of efficiency. The greater the capacity and the larger amount of bonus Zn of the refinery, the higher the efficiency of the refinery.

The purpose of this research is to analyze efficiencies of project management offices (PMOs) using the data envelopment analysis (DEA). As the post-analysis of the efficiency analysis, the causal factors affecting the efficiencies of PMOs were tested. 87 PMOs were used to analyze their efficiencies. In the constant returns-to-scale model, 11 PMOs were completely efficient and 76 PMOs were inefficient. In the variable returns-to-scale (VRS) model, 26 PMOs were efficient and 61 PMOs were inefficient. The efficiency analysis by the DEA has the advantage of deriving the scale efficiency for each DMU. From the result of the post-analysis, it was found that the PMO efficiency was positively influenced by the project portfolio management maturity (PPMM) and the degree of strategic alignments with the business goals. In conclusion, by improving PPMM and strengthening the strategic alignments with business goals, higher efficiency and performance of the PMO can be expected.

In this paper, the effects of novelty-seeking and food involvement on food tourism behavior and the effect of food tourism behavior on intention to revisit the Jeonju Bibimbab Food Festival are studied. Additionally, the effects of attitude, anticipated emotions, perceived behavioral control, and subjective norms on intention to revisit through desire are identified. Three hundred and forty questionnaires are used for the study. These are analyzed with partial least squares structural equation model (PLS-SEM) using SmartPLS 2.0. The results show that two variables of novelty-seeking and food involvement have positive effects on food tourism behavior. It is also found that the effect of food involvement is higher on the food tourism behavior than that of novelty-seeking. This is because survey respondents are mostly domestic visitors, and for them, Bibimbab itself is familiar. In addition, the food tourism behavior has a significant effect on the intention to revisit the Jeonju Bibimbab festival. It implies that people who like to travel to enjoy food are also interested in the food festival.

The Home Energy Management System (HEMS) is a system for the efficient electric power consumption of each household. It can provide real-time electricity cost information according to electricity consumption, and households can immediately control their consumption of electricity. In this study, we analyzed the effects of the HEMS on the stability of demand for electric power. To do this, we analyzed the causal relationship between the amounts of electric power generation and consumption, from the system dynamics perspective. From the analysis, we found that in the current structure, the fluctuation of the quantity of demand became large due to the time delay in households recognizing the electric bill and adjusting their electric power consumption. However, when the HEMS was introduced, it could be seen that electric power demand remained stable since consumers could see their electricity bill in real-time and could manage their electricity consumption by themselves.

Results of the CDI and QODA evaluation developed by OECD showed that Korea’s aid presented low efficiency compared to other aid countries. However, these methods represent a qualitative assessment of the effectiveness of each country’s aid and are not applicable to the evaluation of actual aid projects and the identification of causes of the inefficiency. Therefore, it is needed to grasp the reality of Korea’s aid and to identify the cause of aid inefficiency to set up a better ODA policy. The purpose of this study is to improve the effectiveness of Korea’s Official Development Assistance (ODA) provided to developing countries. To do this, we analyzed the efficiency of ODA provided to 33 recipient countries by Korea through data envelopment analysis method. The effects of three factors, illiteracy, integrity, and GDP, on efficiency were also investigated by utilizing a Tobit regression analysis. As a result of the DEA efficiency analysis, it was found that the average efficiency was about 65.74%. By region, the average efficiency scores of Asia, Africa, Central and South America, and Middle East and Eastern Europe were about 47.8%, 78.9%, 70.4%, and 62.7%, respectively. This indicates that Asian countries are inefficient compared to countries from other regions. It was also found that GDP, integrity, and illiteracy have positive effects on efficiency. The methodology proposed in this study can be used for other studies to create an aid policy that produces efficient results.

The purpose of this study is to suggest efficiency improvement using the analysis of the efficiency of the royalty system for government-funded research institutes (GRIs) belonging to the National Research Council of Science & Technology (NST). Twenty three GRIs’ royalty incomes and expenses (2013–2015) were analyzed using the data envelopment analysis (DEA) model. First, Research Model 1 was used to find out if the obligated expense category’s distribution ratio were efficient. Five Charnes, Cooper and Rhodes (CCR) model organizations and 14 Banker, Charnes and Cooper (BCC) model organizations demonstrated 100% efficiency. With the exception of the obligated expense category, Research Model 2 was used. Seventeen CCR model organizations and 18 BCC model organizations demonstrated 100% efficiency. GRIs were divided into efficient and inefficient organizations using each model, and potential improvements and benchmarking decision-making units (DMUs) were found for inefficient organizations. Second, multiple regression analysis in Research Model 2 was used to analyze the cause of the efficiency to find factors that influenced the transfer of technology and license improvement. Third, there were efficiency differences among research organizations as a result of the efficiency analysis considering the research organization type with respect to the constant returns to scale (CRS) efficiency of Research Models 1 and 2. Thus, different policies should be applied to improve the efficiency. Finally, the possible improvements, future directions and limits of this study are discussed.

The purpose of this paper is to study consumer acceptance of the Home Energy Management System, which is the next generation electronic management system that the Korean government plans to implement in households. The Home Energy Management System is a critical device in maximizing the efficiency of electric energy consumption for each household by using a smart grid. Because it can visualize real-time price information on the electricity, households can easily monitor and control the amount of electricity consumption. With this feature, the Home Energy Management System can contribute to consumers’ total energy savings. This is a major reason why the Korean government wishes to implement it nationwide. Since the Home Energy Management System is a product that applies new technology that has not yet been directly encountered by consumers, there may be a difference in the level of public perception of the Home Energy Management System. Therefore, the impact of consumers’ awareness of the Home Energy Management System on their intention to use is important. To do this, the Technology Acceptance Model is utilized in this study. Traditional research on the Technology Acceptance Model includes awareness of usefulness and ease of use as well as intention to use. In contrast, in this research, an extended Technology Acceptance Model with four additional factors—economic benefit, social contribution, environmental responsibility, and innovativeness—that may affect the consumer’s awareness of usefulness and ease of use, is proposed. To collect the data, the survey was conducted with 287 respondents. As a result, the proposed model proved to be suitable in explaining the intention to use with a 70.3% explanation power. It is found that economic benefit (0.231) and innovativeness (0.259) impact on usefulness of the Home Energy Management System. Moreover, usefulness (0.551) has a bigger effect on intention to use than ease of use (0.338) does. Based on this, it is desirable for the Korean government to pursue a public relations strategy that emphasizes the economic benefits, social contributions, and environmental responsibility that will be gained when introducing the Home Energy Management System. It is effective to focus on consumers who are inclined to accept innovation. In addition, more effective results can be obtained by referring to the usefulness of the Home Energy Management System rather than referring to ease of use.

In 2006, China fully opened up its financial markets. This means that the banking industry is facing a more severe competitive environment, which requires not only the operational efficiency of the bank but also customer satisfaction for the quality of service. As the reform and opening up policy started from the eastern costal areas in China, there are differences in economic development levels by the region, and so are the levels of financial development. Therefore, it is necessary to study the effect of regional differences on bank efficiency. Prior studies also showed a lot of limitations about using data envelopment analysis, in that the efficiencies of the bank are only measured without consideration of other managerial aspects of the service and customer satisfaction. Thus, this study aims to analyze the efficiencies of twenty state-owned commercial banks in five provinces of China. The relationships between bank efficiency, service quality, and customer satisfaction are analyzed. The data used for the analysis was obtained from the 2015 Chinese Banking Statistics. As a result, the average technical efficiency of twenty state-owned banks is as high as 81.9%. It is also found that the bank’s service quality has a positive impact on efficiency and customer satisfaction. In the case of banks that are located in areas with high economic levels, customer satisfaction is lower than that of banks in lower regions. This is because customers in high economic level regions have higher expectations for service quality and it leads to lower customer satisfaction.

The purposes of the study are to estimate inbound tourism demand and to analyze the effect of the Korean Wave and Economic indicators on it. For these purposes, we examined the influence of Korean Wave, GDP, CPI and exchange rate on inbound tourism demand for foreign tourists from the USA, China, Japan and Hong Kong to Korea. In order to measure the Korean wave, the export amount of Hallyu related contents exported to each of the four countries is used. GDP means the GDP of each of the four countries. However, the CPI and the exchange rate are relative to Korea. Penal data on tourism demand, Korean Wave, and Economic indicators from 1997 to 2014 are collected for analysis. Through the various tests for panel analysis model selection, the best fit model proved to be a random effect model. As a result, Korean Wave, GDP, and exchange rate have a statistically significant impact on tourism demand. Therefore, it can be seen that the Korean Wave is one of the important factors for attracting foreign tourists to Korea in four countries. Also, the results show that overseas tourism increases when the economic income of the country is high and the exchange rate is favorable. However, CPI does not appear to have a statistically significant impact on tourism demand. This indicates that tourists are not overly concerned about the cost of the travel country when planning a trip.

Despite the increase in government spending on R&D in South Korea (hereafter Korea), there have been limits in enhancing the impact and commercialisation of research outcomes. A new approach to the current mode of R&D is considered necessary to tackle this problem. In 2014, Korea implemented a new competition policy on national R&D by designating six R&D programmes from four different government departments as Competition-type R&D. The purpose of this study is to examine the actual conditions for adoption and to further promote early establishment and wide implementation of the new competition policy on national R&D, and identify the ways for improvement. In this study, we have approached the case with a life-cycle perspective of plan–management–evaluation of R&D. Multiple sources of data collection included documents, surveys and unstandardised interviews with the staff members in the government sector organisations and agencies responsible for the national R&D management. Based on the results of the analysis, we bring suggestions on three areas of improvement: (a) materialising suitable projects to enrol in the R&D competition programme; (b) suggesting competition models for each stage of R&D life cycle; and (c) establishing the institutional basis upon which the policy may be widely adopted. Finally, we discuss possible improvements and the limits of this study.

In today’s low-growth business environment, efficiency management is becoming more important to improve corporate sustainability. In a chain store, the efficiency of individual stores must be well managed to improve the efficiency of the entire enterprise. To do this, it is important to measure the efficiency of individual stores and to find factors that affect efficiency. The main purpose of this study is to find out the factors affecting the efficiency of chain stores and to analyze the results to find out the implications that contribute to an improvement in efficiency. We measured the relative efficiency of individual stores using data envelopment analysis (DEA) and analyzed the factors that affect efficiency with the Tobit regression model. As a result, we found that the number of items per employee and a competitive environment influence the efficiency of stores. An excessive number of items may cause efficiency to be lowered. Therefore, it is necessary to manage the life cycle of the product, considering the trade-off between assortment and efficiency. Competition helps to improve efficiency to some extent, but too much competition can reduce efficiency.
