Background/Aims: Colonoscopy is the gold standard diagnostic method for colorectal neoplasia, allowing detection and resection of adenomatous polyps; however, significant proportions of adenomas are missed. Computer-aided detection (CADe) systems in endoscopy are currently available to help identify lesions. Diminutive (≤5 mm) and nonpedunculated polyps are most commonly missed. This meta-analysis aimed to assess whether CADe systems can improve the real-time detection of these commonly missed lesions. Methods: A comprehensive literature search was performed. Randomized controlled trials evaluating CADe systems categorized by morphology and lesion size were included. The mean number of polyps and adenomas per patient was derived. Independent proportions and their differences were calculated using DerSimonian and Laird random-effects modeling. Results: Seven studies, including 2,595 CADe-assisted colonoscopies and 2,622 conventional colonoscopies, were analyzed. CADe-assisted colonoscopy demonstrated an 80% increase in the mean number of diminutive adenomas detected per patient compared with conventional colonoscopy (0.31 vs. 0.17; effect size, 0.13; 95% confidence interval [CI], 0.09-0.18); it also demonstrated a 91.7% increase in the mean number of nonpedunculated adenomas detected per patient (0.32 vs. 0.19; effect size, 0.05; 95% CI, 0.02-0.07). Conclusions: CADe-assisted endoscopy significantly improved the detection of most commonly missed adenomas. Although this method is a potentially exciting technology, limitations still apply to current data, prompting the need for further real-time studies.

Korea's government-sponsored research institutes (GRIs) have contributed a lot to the economic development of Korea. They have become major components of the Korean national innovation system. However, in these days, they have been blamed for low productivity and inefficiency, as well as insufficient contribution to national development. This paper argues that the major problem of Korea's GRIs lies in their concentration in a few regions, e. g. Seoul, Gyeonggi, and Daedeok. It argues that they should be fairly distributed among regions in order to contribute to the development of Korea effectively. In this regard, this paper explores the relevant policy options to effectively distribute Korean GRIs among regions. It suggests two categories of distribution scenarios. The first category is based on the types of GRIs to be distributed. This category has three scenarios: existing GRIs, branch institutes of existing GRIs, and new GRIs. The second category is based on the jurisdiction of GRIs. It has also three scenarios: GRI system as an independent sector, GRI-university cooperation system, and integration of GRIs to regional universities. These scenarios have advantages and disadvantages, respectively. Therefore, we must find a rather satisfactory scenario based on the mixture of scenarios of both categories.

The purpose of this study is to examine the predictive effects of intuition, business analytic, networking capabilities on innovation performance. The data was collected using a cross-sectional quantitative survey. A total of 292 useable responses were collected from Thai Processed Food Exporters (TPFE). The findings also indicated that the hypothesized relationships between the independent and dependent variables fit the empirical data. Specifically, it is revealed that strategic intuition, business analytic capabilities, network-based capabilities and dynamic capabilities had a direct effect on dynamic strategy. They also had statistically significant direct and indirect effects on dynamic performance. Based on the results of the correlation test, the researchers developed a dynamic capability model for the development of the dynamic performance of the operators, which included concepts, principles, methods, tools and guidelines. Furthermore, the impacts of intuition, business analytic, networking capabilities on dynamic strategy are also examined in this study. It makes a considerable contribution to the existing literature on dynamic strategy of TPFE, particularly in regards to explaining the performance.

Recently, ERP system is used as a important tool of management innovation for enterprise's survival and development. It is very important to recognize how much influence to organizational performance through ERP system implementation. The purpose of this study is to find out the impact of environmental, organizational, information systems characteristics on successful implementation of ERP systems in Korean SMEs(Small and Medium Enterprises). From previous researches on ERP adoption and implementation, 7 independent variables (competitiveness, government support, top management support, process innovation, project management, IS maturity, and ERP customizing), and 1 dependent variables (successful implementation of ERP systems) are identified. 3 questionnaires were removed from the study because of missing or inappropriate responses, and final samples are 91 SMEs. The results of hypothesis testing show that determinants of successful implementation of ERP systems are top management support and IS maturity. Five variables such as competitiveness, government support, process innovation, project management, and ERP customizing do not significantly influence to successful implementation of ERP systems. The contribution of this study is that it provides an empirical evidence of the causal relationship between ERP adoption factor and ERP success. This study showed that top management support and IS maturity are essential to accomplish successful ERP implementation for SMEs.

Purpose - The purpose of this study analyzes the effect of psychological safety on innovative behavior mediated by job crafting. Design/methodology/approach - This study collected 221 survey data from employees in Korea. Collected data were analyzed using SPSS 25.0 and Macro Process. The multiple regression analysis and bootstrap analysis were hired in order to analyze the data. Findings - First, psychological safety had a significant effect on innovation behavior. Second, job crafting proved a mediating effect in the relationship between psychological safety and innovation behavior. In other words, it has been demonstrated empirically that task crafting, cognitive crafting, and relational crafting, which are sub-elements of job crafting, play a mediating role in the relationship between psychological safety and innovative behavior. Research implications or Originality - This study expanded the study of Job Crafting in that it revealed the mediating role of Job Crafting in the relationship of psychological safety and innovative behavior. Second, this study has novelty in that it has established a sense of psychological safety as an independent variable that promotes innovative behavior, and that it has examined each other's structural relationship by adding a variable called Job Crafting.

This study was conducted to explain airport users' acceptance intention for untact smart devices being introduced at Incheon Airport. Based on the technology acceptance model, perceived usefulness and ease of use influenced attitudes and intention to use. It was verified whether it was affecting the effect. In addition, variables proposed in innovation diffusion theory were selected to verify exogenous variables that affect perceived usefulness and ease of use, which serve as key independent variables in the technology acceptance model. Research results show that perceived usefulness has a high level of positive influence on attitude, whereas perceived ease of use has a low influence and does not show a statistically significant influence. In addition, it was confirmed that most variables of the innovation diffusion theory had no effect on usefulness and ease of use. This means that the key variable in the spread and use of untact smart devices at airports is the perception of usefulness, which means that resistance to accepting new technology is not high.

This study aims to evaluate and identify the patterns of the technological competitiveness of the Korean industry. Such statistics as R&D expenditure and R&D manpower as input indexes, US patent registrations and export sales as output indexse were used. It was turned out that such industrial types as specialized-suppliers industries, scale-intensive industries and science-intensive industries showed relatively strong technical competitiveness. However, resource-intensive industries and labor-intensive industries which had maintained a competitive advantage in the 1970s and the 1980s appeared to be gradually losing their technological competitiveness. These results are by and large in accordance with the trends of export performance. This study conducted the canonical discriminant analysis in order to test the correctness of the patterns displayed in the technological competitiveness of the Korean industry. The result of the analysis showed that the five patterns of technical strength of the Korean industries are significantly independent each other for four respective variables which are used to distinguish industries. This implies that the ex ante industrial classification into five types was correct in terms of the ex post statistics, and that the patterns of technological competitiveness discovered in this study are also statistically correct.

The purpose of this research is to analyze the impact of business scope and technological capability on firm performance in SMEs. Existing studies on business scopes and technological capabilities have focused on the unilateral relationships with financial performances. This study examines the independent and interaction effects of business scopes and technological capabilities on financial performances of SMEs in capital industries. Based on 228 firm-level data, technological capabilities have positively significant impacts on performance. Business scope measured by product variety and number of buyers have been significantly positive relationships to financial performances. Also SMEs with technological capabilities can moderate the effects of business scope on their performances. However, the results show different relationships depending on measurements on business scope, technological capabilities and performance. The results provide interesting findings on strategic behaviors of SMEs when they pursue growth strategy through expanding business scopes and building technological capabilities.
