The trend and outlook of energy supply and demand have an crucial effect on not only energy sector but also korean economy due to the rapid change of energy environments with continuous high oil price such as dubai crude oil price of above $60 a barrel. Specifically, korea is the 9th largest energy consuming nation in the world and the 97 percentages of energy import totally depends on the import of energy resources in korea. Korean economy is influenced directly by the trend and outlook of world energy on account of that. Moreover, Should korea be the annex 1 country having responsibility for reducing its greenhouse gas emissions to 1990 levels by the year 2000, in 2013, The effectuation of united nations framework convention on climate change will affect korean economy severely. In this study, we analyze the supply and demand of primary energy resources such as petroleum, coal, and natural gas. we then suggest the optimal alternatives of energy technology development that play an important part, which will be a temporary bridge, in going forward with hydrogen economy in the aspects of energy policy.

Oil sands are sands containing bitumen similar to crude petroleum. Oil sands had not received enough interest because of the high production cost. However, in the current record-high oil price situation, oil sands are considered as new sources for unconventional oil. In this study, patents analysis was performed for the technologies of production of synthetic crude oil from oil sands. The patents covered were open patents applied in Korea, US, Canada, Japan, Europe, and China. The patents were divided into five detailed technologies; mining and in-situ, extraction, upgrading, fuelling, and other technologies. For oil sands technologies, there have been steady patent applications, since the first patent was applied in 1969. The number of patents applied appeared to be affected by the variation of world oil price. The portion of patents applied in US and Canada was about 90% of the overall patents and it means 05 and Canada have led oil sands technologies. Mining and in-situ technologies, and extraction have been developed actively and occupied more than 77% of the overall patents. However, the number of patents applied for mining and in-situ technologies, and extraction has been constant or started to decrease since 2000. The number of patents applied for upgrading technologies increases recently and it shows the development of upgrading technologies is active now.

Peru is located on Andean Range and faced Pacific Ocean and one of the important oil and gas production countries in the South America. Peru's oil business have been invested by foreign oil companies due to the good investment environment, even though the Peru could not be self-sufficiency in oil. Increase in oil price of the world has contributed to the oil and gas developments and productions in the last few years in many oil and gas blocks, such as in the 1-AB blocks and Camisea gas field within the Amazon jungles. Korean oil companies also have obtained several oil and gas blocks in the Peru in last few year, corresponding with the resources diplomacy of Korean government. Investment is strongly expected to be increased in the Peru's oil business due to positive investment environment, such as low royalty rate, tax avoidance, and the favourable terms of the contract to foreign companies etc.

HTS (High Temperature Superconducting) Transformer has the several useful characteristics in the viewpoints of technical and economical. Especially, an HTS transformer replaces the copper wire coils in a conventional transformer with lower loss HTS wire. In addition, inexpensive, environmentally benign liquid nitrogen replaces the conventional oil as the electrical insulation (dielectric) and provides the necessary cooling for the HTS transformer Therefore, the Life-cycle cost of an HTS transformer is much more attractive than conventional because it is more energy efficient, lighter in weight, smaller in size, and environmentally compliant. HTS transformer can be the best way to replace with conventional transformer in the future. In these days, companies world-wide have conducted researches on HTS transformer. A development project for a 154kV HTS transformer is proceeding at a research center and university in Korea. In this paper, we investigate the expected price of HTS transformer to have a merit in viewpoint of economic aspect. First, life-cycle cost of conventional transformer is calculated and based on this, the expected price of HTS transformer is evaluated. which HTS transformer is competitive against conventional transformer.

The environment of automobile industry in the world is rapidly changing. It is changing of high oil price, technology, environment and construction of competition by newly rising an economic district. Automobile company is focusing on three issue because they want to reinforce competition of automobile industry in the world. That is innovation of production profit management through quality management and Lean. Chance of success is separated in R&D, providing distribution, manufacture, distribution, selling in automobile industry. Emphasis on development process, distribution process, manufacture process, circulation and selling process for strengthening the competitiveness and guarantee. In this thesis, we try to analysis the data set period of automobile production by using survival analysis. While using mean comparison of general statistics commit mistakes, survival analysis can used for including censored data in order to heighten analysis efficiency.

In the international markets, financial variables can be volatile and may affect each other, especially in the crisis times. COVID-19, which began in China in 2019 and spread to many countries of the world, created a crisis not only in the global health system but also in the international financial markets and economy. The purpose of this study is to analyze the contagious effect of the COVID-19 pandemic on the volatility of selected financial variables such as Bitcoin, gold, oil price, and exchange rates and the connections between the volatilities of these variables during the pandemic. For this aim, we use the ARMA-EGARCH model to measure the impact of volatility and shocks. In other words, it is aimed to measure whether the impact of the shock on the financial variables of the contagiousness of the epidemic is also transmitted to the markets. The data was collected from secondary and daily data from September 2th 2019 to December 20th, 2020. It can be said that the findings obtained have statistically significant effects on the conditional variability of the variables. Therefore, there are findings that the shocks in the market are contaminated with each other.

Due to rapid increase in the demand of Natural Rubber (NR) few years ago, NR price sore very higher. The rubber plantation in Thailand expanded very fast to non traditional areas with the result Thai become the biggest NR exporting country in the world. However, the average yield is still lower compared to experimental yield of RRIT (Rubber Research Institute of Thailand) or just 60 % (RRIT, 1998). This is due to many of new rubber planting areas, which are not suitable. The Thai Ministry of Agriculture and Cooperatives thus has set 'The complete cycle development strategies for natural rubber' in the medium-term measures by reducing the rubber planting areas by 300,000 rai (1 rai = 0.16ha) through replanting with oil palm. The aim of this study is to find out land having lowest potential for rubber production (R3) but highest for oil palm production (P1). Find areas which are unsuitable for rubber and can be replaced by oil palm in order to get a better agricultural production. The study was applied upon Krabi province, Thailand. Crops requirement, degree of limitation to crops growth, climatic data, crops yield, soil map, topographic map etc., were used to evaluate land potential for both rubber and oil palm production according to FAO framework (Sys, 1992). An Agro-ecological suitability map for rubber and oil palm were produced. This was done by mean of GIS. The database was generated and guide map for the decision makers in view of suitable crop substitution was prepared.

Most of energy are obtained from oil, coal, and natural gas, most likely, fossil fuel which is limited throughout the world. Recently, high crude oil price, climate change, oil depletion, etc. are main reason to get attention to non-fossil energy including renewable energy in the world. In this study, we studied analysis and design of structure system composed of pultruded fiber reinforced polymer composite (PFRP) which has many advantages such as high specific strength and stiffness, high corrosion resistance and chemical resistance. For the design and construction of floating-type structure, PFRP structural members may be the first choice. Design of tracking-type floating PV generation structure was performed by using the results of the finite element analysis. The structure is fabricated and installed on the water surface. Before the installation of the structure, safety related problems associated with installation and operation are investigated using the finite element simulation and it was found that the structure is safe enough to resist externally applied loads.

The domestic construction market is recovered after a foreign exchange crises but recently it's daunted again because of the sustainable real estate regulation policy by the government. The other aspect, after the WTO(World Trade Organization) system opened overseas construction is growing continuously with growth of international economy and opening of market through world. Moreover, for ballooning oil prices an orders increase by oil-producing countries, the Middle East, gives good chances to domestic construction enterprises. But, the domestic firms decrease on our domain by chases of developing country and high-technology or advanced country. This research will indicate processes of our construction business to analyze performance record about our overseas construction from the 1970s to present. Based on the results it intends to search for problems of our construction enterprises and provide useful analytic data for expansion of overseas construction market.
