With the advent of a recent knowledge-based society, interest in patents is steadily increasing. The patent is an important indicator that can capture the level of R&D investment and technology development. In an era of deepening new protectionism and the pandemic of COVID-19, patents play an important role in sustainable economic development and establishing a strong domestic industrial ecosystem. In this paper, we analyze the impact of patent applications on the corporate performance of the Korean manufacturing industry over the past 21 years from 1999 to 2019. We divide patents into overseas patents and domestic patents and analyze the respective effects on the entire manufacturing industry, ICT industries, and non-ICT industries. Major findings are summarized as follows. First, patents have a positive effect on both exports and sales of Korean manufacturing companies. Second, overseas patents have a greater impact on corporate performance than domestic patents. Third, Patents have a more positive effect on ICT industries than on non-ICT industries.

The purpose of this study is to analyze human safety culture of the railway driver in domestic railway industry. This study proposes safety culture improvement of domestic railway by intensively comparing railway safety system overseas to reinforce domestic railway safety. Domestic railways well known the well-organized railway safety culture has brought up safety issues on their process of private management. With this process, also, domestic safety culture is requested by increasing sense of the safety for general public. This study expects Korean railways to become a well-organized that as removing insecure factors of domestic railway based on result comparing and analyzing the manual, factors and requirements of guideline for internal and external safety culture.

The purpose of this study is to propose a methodology for estimating greenhouse gas emission reduction through HFCs used in the foam industry. This study investigated characteristics of HFCs and greenhouse gas emissions from production processes in the foam industry, which uses HFCs as a blowing agent. Also, we investigated fluorinated gas removal technology to determine a proper technology for the foam industry. And we confirmed the criteria and characteristics of External Project for methodology development. According to criteria of External Project and foam industrial process emission, a methodology for calculating the amount of greenhouse gas emission reduction in foam industry was developed. Lastly, we analyzed the amount of greenhouse gas emission reduction and KOC (Korea Of Offset) in the foam industry based on the domestic government's plan to reduce HCFCs and imported amount of HFCs used as a blowing agent. The results of this study demonstrate that linking greenhouse gas reduction in the foam industry and the domestic greenhouse gas reduction system can contribute to achieve the domestic greenhouse gas reduction goal.

Since 2010, it is estimated that the old building to be dismantled potentially will be about 8.9 million house in domestic country. Consequently, now domestic demolition market size of about 1.5 trillion won is forecasted to be grow rapidly into the size of 5.8 trillion won. But in the domestic country, preparation of the raw and regulation for the demolition industry is very insufficient compared with advanced country, and the related research is also very insufficient. Therefore, in this study, it is performed to analyse and predict a trend of domestic demolition market after analysing a current trend in overseas demolition industry. A demolition industry is a related industry fallen behind over 25 years compared with a construction industry. The exact analysis of those trends will make it possible to set the standard for demolition waste management. Also this study suggests methods be able to develop the demolition industry into main area of construction industry through those analysis.

The purposes of this research are investigating the domestic and foreign situations and presenting methods to be able to raise the competitiveness of the power IT industry. For the analysis of domestic situations, 70 companies related with power IT were surveyed. Thus, the problems the power IT industry is now facing are summarized and solutions for them are also suggested. If these solutions are practiced, the power industry could provide higher quality electricity and belong to the prior group of global power society.

In 1967, cheese was first produced with small scale of mozzarella cheese in Korea. The processed cheese market was highly grown after putting on the market of sliced cheese in the late 1980's, and the various products that complied with well-being trends such as organic and high functional cheese have been produced in the 2000's. The natural cheese opens up a new domestic market after producing camembert and brie cheese in the end of 2004. At present. the cheese market is expanded with differentiated products such as high value added and high functional cheese. The size of domestic cheese market remains about 200 billion won, but it is expected to go over a trillion won on account of growing preference of natural cheese with well-being trends. To promote domestic cheese industry, differentiation policy of raw milk price for cheese, diversification of cheese products, financial support to farm-made cheese industry and automation and processing development to improve productivity should be taken into account in the future in Korea.

Lately, as domestic smart phone users exceeds 10 millions, Korea entered into real smart era in which smart contents market grows very quickly. One of feature for smart contents market is that there is few entry barrier for market penetration. So, it is essential for domestic digital contents providers to transform existing digital contents into smart contents to protect the entry of foreign firms into domestic market and to take advantage of opportunities to advance to foreign contents markets. The objective of this study is analyzing strategies of abroad companies which has penetrated into smart contents market successfully and classifying them systematically and the way to execute the proposed strategies. Future works of companies and governments to expand smart contents markets can be summarized as follows. First, they must prepare reliable data to elicitate proper market penetration strategies. Second, it is highly desirable to fuse contents industry and culture industry together. Third, it is urgent to formulate policies to promote SOHO contents companies.

Waste heat exhausted from seven types of the domestic industry was surveyed, which include food, fibre, paper & wood, chemical, ceramics, metalworking and others. The databases of waste heat for each industry were made by using ACCESS software of Microsoft, and data were analyzed to get correlation between waste heat and purchase energy. The volume of usable waste heat is estimated to be 9,169,000 TOE in the year of 2000, when the minimum available temperature is set as $100^{\circ}C$ for waste gas, $30^{\circ}C$ for hot water and $100^{\circ}C$ for steam considering the condition of waste heat exhausting facilities and surroundings. This volume of waste heat is approximately 11.9 percent of the purchase energy of the domestic industry.

Construction industry has become a larger and highly competitive industry. A successful construction project cannot be achieved only by efficient and fast construction techniques but also reasonable material cost and adequate transferring time of materials to installation. The steel industry in East Asia has become the mainstream in overall steel industries in over the world during the middle of the 21st century. China, Japan and Korea has been the main exportation countries. However, even though the international economic failure, China has increased the exportation amount and became an only exporting country which must be considered a serious problem regarding competitiveness in the international steel exportation industry. Thus, this study analyses the factors affecting the supply and demand amount of reinforced bars in the domestic field and moreover suggesting a unit cost prediction model using the System Dynamics simulation methodology, one of powerful prediction tools using cause-effect relationships. It is expected that this study contributes to the domestic steel industry growth in competitiveness in the international industry. In addition, the methodology used in this paper presents the frameworks for appropriate tools for market trend analysis and prediction of other markets.
