Trend of R&D expenditure in Korea during the last 10 years, the R&D expenditure has been constantly increasing at an average rate of 10%. The government R&D ekpenditures or subsidies are increasing rapidly But the studies of evaluating impact of government R&D subsidies are few. This study attempts to empirically investigate the effects of government R&D subsidies on private firm's R&D investment in Korean industry by using Propensity score matching method which sign as to whether the relationship between government subsidies and private R&D investments is on stimulating or displacing private R&D expenditures. Empirically, a firm with government R&D subsidy are 733 million dollar more expenditure then don't receive any government R&D funding. Also Government R&D subsidies greatly increase (statistically significant) company financed R&D expenditures only for large firms but had no effect on the R&D expenditures of small & medium sized firms and venture firms.

The purpose of this study was to examine the effect of physical fitness improvement program on work intensity of persons with Down syndrome. For this, 8 adults with Down syndrome participated in program and were evaluated. The physical fitness improvement program consisted of grasp, lifting, carrying exercise for 12 weeks, 1 day a week for 2 hours per session. Compared with pre-program conditions, participants in program improved significantly in right grasp power, lifting ability but there was not significant improvement in carrying ability. In view of work intensity, work intensity level of two subjects was changed from average to hard in lifting. One subject was changed from very light to average and two subjects was changed from light to average in carrying. This results suggested that physical fitness improvement program was helpful for promotion the intensity of adults with Down syndrome.

There are two major problems with current National GAP system. One was false in traceability record because it was written or inputted by farmers or distributers and no other measures to check the accuracy was valid. The other was incapability of tracking back and recalling the contaminated agricultural products. For solving these matters, IT convergence model which combined information technology with agricultural experience is elaborated. In IT convergence model, video analytic system classifies every activity depending on the pre-programmed farming process and create the traceability data automatically. Also real time trace system based on USN would solve the problem of tracking back. This system transmits the present location and monitors data of agricultural products from farm to table at all times.

Micro-scale copper bumps for build-up PCB were electroplated using a pulse-reverse method. The effects of the current density, pulse-reverse ratio and brightener concentration of the electroplating process were investigated and optimized for suitable performance. The electroplated micro-bumps were characterized using various analytical tools, including an optical microscope, a scanning electron microscope and an atomic force microscope. Surface analysis results showed that the electroplating uniformity was viable in a current density range of 1.4-3.0 A/$dm^2$ at a pulse-reverse ratio of 1. To investigate the brightener concentration on the electroplating properties, the current density value was fixed at 3.0 A/$dm^2$ as a dense microstructure was achieved at this current density. The brightener concentration was varied from 0.05 to 0.3 ml/L to study the effect of the concentration. The optimum concentration for micro-bump electroplating was found to be 0.05 ml/L based on the examination of the electroplating properties of the bump shape, roughness and grain size.

The paper investigates empirically the determinants of standardization activity at the industry level, focusing on market structure. The enactments or amendments of collective standards is used as the proxy variable for standardization activity. The independent variables, in addition to market structure, are technological opportunity, factor intensity, export ratio, and industry characteristics(assembly). We estimated the logistic regression model(so-called Logit), using the pooling data for 9 Korean industries, including foods, textiles, chemicals, nonmetallic minerals, metals, electronics and electrics, machinery, automobiles, and shipbuilding, over 2006-2009. The empirical finding shows that market structure has no any effects on the enactments or amendments of collective standards in Korea. This might infer that oligopolistic firms devote themselves to de facto standards determined by market rather than de jure standards such as collective standards and Korean Standards(KS). Besides market structure variable, whereas technological opportunity and assembly characteristics are likely to relate positively with the enactments or amendments of collective standards, capital intensity and export ratio have no any relationship with industrial standardization, respectively.

In the PACS system, the radiology image(X-ray) and its report are saved as separated parts. The exchange of the radiology image between clinics that installed this system are easily achieved by the DICOM standardization. But it is difficult to exchange the radiology report between clinics because a solution of PACS system is different according to manufacturers. The radiology report should be unified the vocabulary and the type of code for effective sharing and exchanging, and also the radiology image and its report should be integrated for the accurate analysis. In this paper, we propose the sharing system of medical information based on HL7-CDA, it defines the templates and converts the structured documents. For this purpose, we design the XML schema of the radiology report and turn the DICOM files into defined schema. The HL7-CDA documents based on XML is easily displayed on web browser and can help the diagnosis by inserting the radiology image.

Innovation, especially business process innovation, has evolved into a core focus area for all successful organizations. To ensure long-tenn survival, an enterprise must place innovation at the top of daily business operations to drive desired revenue stability and growth. Business Process Innovation is a key success factor for the next generation enterprise. Companies need to nurture an environment that encourages and enables process innovation. Business Process Management (BPM) must become the focal point of innovation initiatives. But the most BPM solutions are for large company. The cost is too high to build for small and medium sized company. We need the light and easy BPM solution for small and medium sized company. In this paper, we introduce the SESS which is BPM solution for small and medium sized company.

This article uses panel data of thirteen prefecture-level cities in Jiangsu Province from 2007 to 2021, and adopts entropy method, SBM model, and coupling coordination degree model to empirically study the development level of new model of urbanization and green economic efficiency in Jiangsu Province and the coupling coordination relationship between them. The results show that: the coupling coordination was in a moderate disorder and on the verge of disorder in 2008 and 2009. However, it steadily improved after 2010, and even witnessed a significant increase from 2018 to 2021. After that, it shows a high-quality coordination in 2021, indicating that the level of coordination between urbanization and green economic efficiency in Jiangsu province is steadily improving. Analyzed from a spatial perspective, the overall development of the regions in the province is sound and the coordination is growing at a significant rate, but there are still certain gaps in the coordinated development between the regions.
