The Korean miracle of economic growth or development has been quite well known across the world up to now, while being subject to theorization of its model. Compared with this, however, it is quite surprising to see how little about the spatial aspect of Korean development has been exposed in the field of development studies. In fact, for Korea, competent regional policy has turned out to be an important success factor for the spatial upgrading of a low-tech growth regime into a hi-tech one. This paper dissects Korea's regional policy experiences in three aspects from which it draws up a three-tier lesson. The first aspect is the conventional (overall) regional spatial upgrading policy of a developmental regime put in place since the 1960s onwards. The second is the new regional policy tailored to the regionalization of technological and industrial diffusion for new knowledge-based economy. The third is the prospective regional policy for the future advancement of the Korean economy.

Bio-oil has attracted considerable interest as one of the promising renewable energy resources because it can be used as a feedstock in conventional petroleum refineries for the production of high value chemicals or next-generation hydrocarbon fuels. Currently, catalytic vapor cracking is considered the most potential upgrading method for stabilization of bio-oil, which is a pre-process required prior to feeding bio-oil into refineries. This review introduces the recent research and development trends on bio-oil upgrading via catalytic vapor cracking, focusing on catalysts and upgrading methods used.

This paper highlights how Thailand upgrades its positions in global value chains in high-tech, mid-tech and low-tech industries represented by electronics, automotive and frozen seafood, respectively. In the electronics industry, there are not many capable firms in the upstream segment like semiconductors. Nevertheless, transnational corporations in segment like hard disk drive began to invest in process R&D and collaborate more with local suppliers, universities and public research institutes in human resource and technological development. In the automotive industry, several Japanese car manufacturers such as Toyota, Honda, Nissan, and Isuzu set up R&D/Technical centres in Thailand since 2000s. This prompted Japanese and local part suppliers to also invest more in engineering, design and development activities. Some local universities offer as well engineering programmes specifically targeting the automotive industry. In the frozen seafood industry, several Thai firms have developed new ready-to-eat products, own brands and international distribution networks. They started to become transnational corporations investing in both developing and developed countries.

This paper presents the practice of multitexturing in the Internet for enhancing the image quality of 3D contents, where the attributes of objects such as textures are dynamically changed. We explain the empirical results of realizing the X3D nodes related with multitexturing in the recent X3D viewers, and discuss the directions for upgrading X3D viewers that satisfy the user requirements and the advanced graphics accelerators.

Non-conventional energy is considered as important future energy source, as conventional energy has limitation for its capacity. The demand on value added process in heavy oil/oil sand bitumen is increasing in particular. Solvent Deasphalting (SDA) process for Deasphalted Oil (DAO) is used as heavy oil upgrading process in existing refinery process. SDA process for heavy oil upgrading has been already commercialized by leading countries. SDA R&D projects have been carried out actively by those countries. In this study, patent analysis for SDA technology development was carried out. From 1970's, when SDA patents were applied, the patents in Korea, USA, Japan, Canada and Europe were searched and distributed to extraction, recovery, solvent and etc. 334 patents were selected relating to heavy oil upgrading SDA process. The application status of SDA process patents showed a tendency to increase slightly. The number of patent applied was USA patent 131 (39%), Canada patent 83 (25%), Japan patent 35 (11%) and Korea patent 6 (2%). It will be necessary for efficient use of energy resource to support SDA R&D by government.

Biogas is a renewable fuel from anaerobic digestion of organic matters such as sewage sludge, manure and food waste. Raw biogas consists mainly of methane, carbon dioxide, hydrogen sulfide, and water. Biogas may also contain other impurities such as siloxanes, halogenated hydrocarbons, aromatic hydrocarbons. Efficient power technologies such as fuel cell demand ultra-low concentration of containments in the biogas feed, imposing stringent requirements on fuel purification technology. Biogas is upgraded from pressure swing adsorption after biogas purification process which consists of water, $H_2S$ and siloxane removal. A polymer electrolyte membrane fuel cell power plant is designed to operate on reformate produced from upgraded biogas by steam reformer.

Firstly, this article expounds that business service industry plays an important role in adjusting industrial structure, transforming mode of economic growth, improving people's living standards, enhancing Enterprise's Kernel Competitiveness and promoting the development of service industry. Then it analyzes the development of business services in Shandong from two perspectives. The first perspective, by using methodology for statistical analysis, it will review the development scale, professional level, the number of opening units, quantity of employment, and operating revenue of business services in Shandong. On this basis, the article will summarize its development characteristics, experience and existing shortcomings. The second perspective, by using comparison analysis methodology, to compare the development of Shandong with Jiangsu, Guangdong, Zhejiang and Shanghai's and found the subjective and objective factors that restrict the development of business service industry in Shandong. In the light of restricting factors, countermeasures have been developed based on the experience at home and abroad. These countermeasures will contribute to promoting the optimization and upgrading of industrial structure, improving industrial competitiveness and speeding up the economic development rapidly and stably.

This paper contains an introduction to industrial problems, solutions, and results conducted with the Korea Association of Machinery Industry. The client company commissioned the problem of upgrading the method of identifying global supply risky items. Accordingly, the factors affecting the supply and demand of imported items in the global supply chain were identified and the method of selecting risky items was studied and delivered. Through research and discussions with the client companies, it is confirmed that the most suitable factors for identifying global supply risky items are 'import size', 'import dependence', and 'trend abnormality'. The meaning of each indicator is introduced, and risky items are selected using export/import data until October 2022. Through this paper, it is expected that countries and companies will be able to identify global supply risky items in advance and prepare for risks in the new normal situation: the economic situation caused by infectious diseases such as the COVID-19 pandemic; and the export/import regulation due to geopolitical problems. The client company will include in his report, the method presented in this paper and the risky items selected by the method.

Various digital contents generation techniques are widely utilized by upgrading PC and mobile device. In this paper, we propose sketch effect simulation based on real drawing pieces. For this, we analyze Vincent Van Gogh's drawing pieces; and then construct DB by extracting sketch stroke pattern of each object. From this database, we select stroke pattern at each object, and then, apply it. Our algorithm can generate similar effect look like real drawing piece. It may be utilized various contents such as children's painting education book.
