The status of Ppuri industry, including foundry industry was analyzed through statistical surveys over the past 10 years from 2009 to 2018, and summarized for each six Ppuri industries' points of view. Various statistics of Ppuri industry defined by the KSIC (Korean Standard Industry Classification) was obtained, and the status of Ppuri industry was identified through a sample survey of 5,000 companies from more than 30,000 target business companies of Ppuri industry. Throughout the analyzing process, we presented a variety of indicators, such as the number of the Ppuri companies and its ratio, regional distribution through Korean provinces, number of workers, characteristics by age group, sales, profit rates, etc. By devising a comparative method to measure the relative strength of Ppuri industry in Korea, Germany, and Japan, we have presented the competitiveness index change over the 10 years of time. The competitiveness index can be effectively and meaningfully used during various activities of the development of Ppuri industry in the forth coming future. With the current obtained data, we figured out the status of each 6 Ppuri industries, regional distribution, status of workers, sales and profit rates. We also suggested various proposals for strategy and policy making for each sector with urging voluntary response from Ppuri industry.

In this paper, we analysis a competition to organize knowledge map as initial prepare stage based on intellectual property. We also propose the method that can be used to constitute knowledge map related in area to use basic data. In order to extract analysis data, we choose LED as an analysis technology. We provide the result of total analysis for LED application area through analysis of patent level after we extract recent patent ratio, activity index, patent family size, cites per patent as center of patent data.

The governments of Korea, China, and Japan have operated comprehensive research institutes for railway technologies. Korea Railroad Research Institute (KRRI), China Academy of Railway Sciences Corporation Limited (CARS), and Railway Technical Research Institute (RTRI) are representatives of comprehensive railway research institutes in each country. KRRI was found to be the most advanced in the quantitative competitiveness of patents. In terms of qualitative competitiveness, KRRI has strength in civil engineering, whereas RTRI has strength in electricity. KRRI was found to have the greatest efforts in securing competitiveness in overseas property rights. By comparing the publication of papers, CARS published the most papers. On the other hand, from 2015, KRRI showed an upward trend and published the most papers. By examining the impact of the papers by the citation, KRRI was found to have higher competitiveness than the other two institutions. In the future, it will be necessary to perform big data analysis on patents and papers of the three organizations, derive the key research areas and promising technology areas for each institute, and establish a mid-to-long-term development plan for railway technology based on scientific evidence.

The study analyzes the shifts of international competition in the digital products market between South Korea and major FTA partners. The analysis utilizes trade statistics to calculate changes in the volume of trade, and in competitiveness between FTA partners. The target countries for this analysis include USA and the European Union with whom Korea has made agreements recently, and the period is set for the decade from 2000 to 2009. The trade records of the UN are employed to investigate the indexes of each country: trade structure and market share of digital products, the trade specialization index (TSI), and annual change of revealed comparative advantage index (RCA) against global market and both the American and EU markets. This analysis shows clearly the status quo of the development and growth of the international competitiveness of South Korea. The study will improve the understanding of international competitiveness in digital products and contents industry, which is rapidly evolving, and of the resulting industrial structure.

This study aims at analysing the export competitiveness of the six largest countries which have the highest market share in world automobile market, namely Japan, USA, China, Germany, South Korea and France for the last seven years between 2000 and 2006 in Chinese automobile market by using revealed comparative advantage index(RCA), comparative advantage index by country (CAC) and exporting similarity index(ESI). On analysis of the RCA index, it showed that the export competitiveness of Korean automobile in the world market was high following Japan and Germany, but it ranked the lowest competitiveness among the six trade competitors in Chinese automobile market. In other side, it is also made sure that the formidable competitors of Korean automobile export in global market are Germany and Japan. Therefore, South Korea needs to raise its ability to adjust to improvement of the international competitiveness in exports through close cooperation between government and automobile export enterprise and consistent monitoring about Chinese automobile industry and market.

In this study, a number of distance-dependent competition indices on tree-level which incorporate the tree sizes and distances to competitors, and traditional stand-level density measures were estimated from the data compiled with position-dependent survey in a Pinus densiflora stand. The performance of the estimated competition indices was examined by comparing the relationship with the diameter growth, and a dbh growth function, in which the competition index is considered as a one of influence factors, are developed. In the searching method of competing trees, the competition index estimated with $30^{\circ}$ competition interrupting angle showed the highest correlation with the annual dbh growth, while the expanding the competing zone distance had no significant effect on the performance of competition index in estimating annual dbh growth. The most of the examined stand-level competition indices, based on distance-dependent single-tree competition indices, were evaluated to describe similarly the stand competition status. As a result of partial correlation analysis in which the effect of age and site index are eliminated, Alemdag's mean competition index and relative spacing index were determined to have the highest correlation with dbh. The relative spacing index, which can be easily measured in field without measuring the position of individual trees, was considered to be a better suited one for estimating mean dbh of a stand. Among distance-dependent competition indices on tree-level, Hegyi's competition index showed the best performance in their correlation with annual dbh growth, if eliminated the effect of site index and dbh. This enabled to derive the following annual dbh growth function of individual trees which incorporate age, dominant height, dbh and Hegyi's competition index as influence factors : $$dbh^{\prime}=3.975362676{\cdot}age^{-1.099274613}{\cdot}ho^{0.199893990}{\cdot}dbh^{0.269430865}{\cdot}HgCI^{-0.353643587}$$ This function is coincided to the growth principle in which site index has a positive effect on the annual dbh growth, while high age or competition causes to reduce the annual dbh growth, and can be used as a function in single tree growth model.

This study evaluates industrial competitiveness of 34 industries in the 41 countries in terms of several trade indices such as value-added RCA(VRCA) and value added intra-industry trade(VIIT). Conclusions are as follows: First, China is still showing week evidence to replace or overtake Korea in terms of VRCA. Second, it is not supportive of the assertion that the gap between Japan and South Korea had widened in the 1995-2011 period. Third, Korea's exports pattern in the manufacturing sector has shifted from the one featured by developing countries(re-exportation of final goods produced using imported intermediate inputs) to that of the developed (exportation of intermediate goods). According to dynamic panel analysis regressing the RCA gap on the IIT gap, intermediate-goods RCA and the market share gap, the estimated coefficient of the gap between value-added IIT and gross IIT is 0.253 and statistically significant at the 2% level. This implies that increases in IIT or intermediate-goods trade to sustain the global competitiveness are the main reasons for the gap between value-added RCA and gross RCA.
