Drawing on the organizational learning theory, we argue that international patenting allows firms to assess the potential value of their innovation in host countries and find out latent local competitors. The information obtained from international patenting enables firms to make refined innovations that facilitate export performance. However, structural inertia and old knowledge can impede learning from international patenting. Thus, we expect larger firms and older firms to display greater reluctance to use the knowledge obtained from international patenting. Our empirical analysis of Korean pharmaceutical companies from 1998 to 2010 shows that international patent application increases export intensity but firm size and age weaken the positive effect of international patenting on export performance.

The paper investigates the determinants of firm's standardization activity in the Korean manufacturing industry. Standardization variables as dependent ones are standardization management at the firm level, accreditation activity, domestic standards utilization, and international standards utilization. The independent variables include innovative activities(R&D intensity and patent application), firm size, export ratio, networks, and firm's organization characteristics. We estimated the logistic regression model, using the data from 636 Korean manufacturing firms. The empirical findings are as follows. First, R&D intensity doesn't have any influence on standardization activities, except the utilization of international standards. Second, patent application has a positive effect on standardization management at the firm level and accreditation activity, respectively. Third, the inverse U-shape hypothesis relating firm size is accepted for standardization management and accreditation, respectively. Fourth, the level of chief executive officer's interest on standardization is a very important factor in determining firms' efforts to participate standardization process, regardless of types of standardization activity.

The paper investigates the determinants of firm's standardization activity in the Korean service industry. Standardization variables as dependent ones are standardization management at the firm level, domestic standardization activity, and international standardization activity. The independent variables include innovative activities(R&D intensity and patent application), firm size, export ratio, network, and firm's organization characteristics. We estimated the logistic regression model, using the data from 102 Korean service firms. The empirical findings are as follows. First, R&D intensity has a positive effect on international standardization activity, but not on the standardization management at the firm level and domestic standardization activity. Second, patent application has a negative effect on the standardization management at the firm level. Third, firm size doesn't have any influence on firms' standardization activities in the service sector. Fourth, the level of chief executive officer's interest on standardization is a very important factor in determining firms' efforts to participate standardization process, regardless of types of standardization activity.

Official statistics which are collected for governments and the community can be used to assess the effectiveness of governments' policies and programs. Thus, official statistics should be collected and presented based on correct findings. Erroneous official statistics will lead to lower quality results in assessing those policies and programs. Many statistical agencies, today, use on-line analytical processing (OLAP) data cubes which support OLAP tasks like aggregation and subtotals as a key part of their dissemination strategy of official statistics. Confidentiality protection in data cubes also should be made. However, sensitive parts of data cubes including micro data may be disclosed by malicious inferences. The authors have suggested an inference control process in OLAP data cubes which preventing erroneous cube creating and securing cubes against privacy breaches. The objective of this study is to establish a strategy for inference control of official statistics using the inference control process by taking the case of the Patent Application Expense Support Project.

There are more than 2000 minerals on earth, and it has been implemented in various fields such as environment, architecture, livestock, chemistry, pharmaceuticals. Clay minerals are considered that they can change the physical and chemical properties through the adsorption and release of metal ions. Although domestic deposit of non-metallic mineral resources is approximately ninety-six billion tons, its application is limited and has hardly been used in high value-added industries involved in medicine, medical supplies, and functional food materials. Bentonite and zeolite are already used for cosmetic purposes and also used in living goods and packing materials. However, direct application to the food industry is relatively very rare. Since records regarding the intake of minerals for foods and medicines are found in the old literatures, the utilization of non-metallic minerals as food materials appears to be highly profitable. According to the trends in patent research for food and mineral resources, the company plays a main role for the development of the food containing non-metallic minerals in USA, and the trends confirms that this industry is emerging. Here, we provided the information about domestic and foreign patent trend for food industries involved in mineral resources and the application of mineral resources in the food industries. We also covered the domestic regulation regarding usage of mineral resources in food, and proposed domestic application plan for food production using mineral resources in the future.

As interest in advanced countries regarding the convergence technology development increases, a methodology for identifying the core convergence technology that has a large spill-over effect on the technology and industry is required for the nation's competitiveness enhancement in the convergence technology field. Based on patent citation network analysis using 1,124 USPTO patents in the ICT convergence technology field of the smart factory, this study examined the proposed heterogeneous technology convergence index as a tool for measuring the convergence characteristics of the spillovers compared to other indexes (i.e. other sector ratio index and homogeneous technology convergence index). The proposed heterogeneous technology convergence index was used to investigate core technology sectors among ICT technology sectors of smart factory identified by government ministries. Results found 6 core ICT convergence technology sectors including the manufacturing execution analysis application sector. Also, this study conducted blockmodeling analysis using the IPC codes of patents in the manufacturing execution analysis application sector, and identified that the blocks representing the electronic communication and electric digital data processing technology sectors (Block 3 & 4) are related technology sectors which can be converged with core technology. Based on the findings, the implications for the convergence technology development planning of the smart factory field are discussed.
