This study, tried to describe the corporations and competitiveness of IT industries in Korea and China as well as the general trend in trade using import-export structure. Further, based on trade intensity index, revealed comparative advantage index, Grubel-Lloyd index, constant market share, the trade structure between Korea and China was analyzed for the equipment in the fields of communication, information, broadcasting and their parts. The results are; first, since 2004, China has been catching up with Korea in the number of their companies listed in the global top 500 conglomerates. Second, the trade intensity index increased in 2007 4.57% up from 2002, showing increasingly closer connection between the two countries in the area of communications equipment. Third, according to revealed comparative advantage index, Korea's info-communications equipment seems to comparatively lag behind, but in terms of import-export structure is in the black. Fourth, in recent years, Korean equipment's market share in the Chinese market has been dropped due to the weakening competitiveness and the changing commodity supplies.

Although the era of very large telescopes has come, small telescopes still have advantages for fast follow-up and long-term monitoring observation. Intensive monitoring survey of nearby galaxies (IMSNG) aims to understand the nature of the supernovae (SNe) by catching the early light curve from them with the network of small telescopes from 0.4-m to 1.0-m all around the world. To achieve the scientific goals with heterogeneous facilities, three factors are important. First, automatic processes as soon as data is uploaded will increase efficiency and shorten the time. Second, searching for transients is necessary to deal with newly emerged transients for fast follow-up observation. Finally, the Integrated process for different telescopes gives a homogeneous output, which will eventually make connections with the database easy. Here, we introduce the integrated pipeline, 'gppy' based on Python, for more than 10 facilities having various configurations and its performance. Processes consist of image pre-process, photometry, image align, image combine, photometry, and transient search. In the connected database, homogeneous output is summarized and analyzed additionally to filter transient candidates with light curves. This talk will suggest the future work to improve the performance and usability on the other projects, gravitational wave electromagnetic wave counterpart in Korea Observatory (GECKO), and small telescope network of Korea (SOMANGNET).

This study was carried out to offer the basic data for more qualitative lives of the middle-aged women through their health maintenance and control. So, the researcher reviewed and analyzed the health problems of the middle-aged women, the differences of main symptoms in each subject, positive ratcs in screening tests, the difference of screening tests with age and the correlation of obesity and blood pressure with screening tests. All subjects were 218 women(40-59years) who had a check-up at a comprehensive health check-up center in K University Hospital in Seoul from July 1, 1998 to August 31. 1998. Questionaires were developed to get subjects, general characteristics. main symptoms, medical examination and diagnosed disease by the researcher referring through the questionaires of comprehensive health check-up center and the medical recorders were used as a tool of study. The researcher analyzed the data with SPSS PC+ ; the distribution of the subjects, general characteristics and main symptoms with percentage : the difference between main symptoms and screening tests with X$^2$-test, ANOVA. The results are as follows. 1) Among the age distribution, most were 40-45 years old and unemployed. 2) The most common complaints were indigestion in digestive system, cough in respiratory system, heart beat in cardiovascular system, general sweat in endocrine system. edema in urinary system, easy bruise in hematologic system, backache in musculoskeletal system, headache in psychoneurologic system, lochia in gynecology, itch in dermatology system, eye ball pain in visual system and tinnitus in auditory system. 3) In main symptoms according to age, the 40-45 age group had a higher rate of complaints in digestive system and gynecology than other age group ; the 46-49 age group in endocrine system. 4) The main symptoms according to diagnosis had no difference statistically. 5) The screening tests which showed high rates of abnormality were mammography(the highest), abdominal ultrasonography, upper gastrointestinal series/gastrofiberscopy, PFT. In all age group the highest rate of abnormality was seen in mammography. 6) In screening tests according to age. the 46-49 age group showed higher positive rates of pap smear, blood sugar test, urine test than any other age group ; the 50-55 age group showerd higher positive rates of obesity, BP, chest X-ray, abdominal ultrasonography, ESR, SGOT, CRP and urine micro. 7) In correlation of obesity with screening test, the obesity group showed higher positive rates of blood pressure, chest X-ray, abdominal ultrasonography, HCT and CRP than the normal weight group. 8) In correlation of blood pressure with screening test, the hypertension group showed higher positive rate of obesity, chest X-ray, abdominal ultrasonography, pap smear and blood sugar than the normal blood pressure group. In conculusion, the middle-aged women have various physical symptoms and affected by age. The obesity and BP have an important effect on the health of the middle aged women. Therefore, this study is considered significant as data for qualitative lives of the middle-aged women playing an important part of family health care by catching of their health problem complaints for prevention of disease and promotion of health.

In this study, we established a framework for measuring the internationalization of innovation systems. Through this, we try to make a comparative analysis on the atomic energy and space sector in Korea. According to our analysis, the atomic energy sector has a higher level of internationalization in its innovation system with technological level than the space sector. This study indicates that the internationalization of innovation system is an important factor for catching up a leader. The framework, which was developed in this study, could be applied to many case studies on an international leadership of innovation system. In addition, it could provide some implications for technology management, especially in the sectors which fell into a strategic dilemma.

The technology transfers from public institutions have positioned themselves as knowledge conduits for stimulating firms' capabilities under 'catching-up' economy paradigm. While this view is still relevant, the policy for public technology needs to be extended to a more marketoriented way. This study explores how public technology affects the financial performance of demanding companies by comparing the revenues and profits of 'technology commercialised group (TC)' and 'in-house research group (InR)'. The estimation results by hierarchy regression suggest that the size and the patents of TC firms have a more influential impact than InR group, although the ratio of maintaining research staff was reported an inverse relation. The contribution to the operating profit seems to be indifferent between the groups. The positive impact of public technology over the firm's performance is highly related to the technology commercialisation capability, signalling that the aim of technology transfer needs to gear toward the enhancement of commercialising capabilities rather than the promotion of technology transactions.

Most of the movies currently being created are used by CG. As for movie of today, the location of visual effect from film business rose highly with CG introductions to do not ask a style. The CG gets attention recently, and expand a market at rapid pace, the biggest reason are development of software and computer hardware. Advancement of computer technology and technique discharge numerous VFX artists therefore visual effect are possible to deliver with low-budget feature and commercial films more common. As for CG fields Hollywood in United States has most advancement of the computer techniques that create a lot of visual effect artists. However CG techniques of Korea also developed absurdly, because movie market of Korea is getting bigger. Korean CG technology get catching up at the CG techniques of Hollywood every year, however goal of this research in order to study is current address and future possibility of development of Korean CG. The CG example which from the movie was already screened that in the depth. Through movie of existing and knows a different partial authorization, tries to observe the possibility of development of future Korean CG fields.

Industrial clusters are geographical concentrations of interconnected companies, specialised suppliers, service providers, firms in related industries, and associated institutions (for example, universities, standard agencies, and trade associations) that combine to create new products and/or services in specific lines of business. At present, the concept of industrial cluster becomes very popular worldwide, policy makers at national, regional and local levels and business people in both forerunner and latecomer countries are keen to implement the cluster concept as an economic development model. Though understanding of clusters and related promoting policies varies from one place to another, the underlying benefits of clusters from collective learning and knowledge spillovers between participating actors strongly attract the attention of these people. In Thailand, a latecomer country in terms of technological catching up, the cluster concept has been used as a means to rectify weakness and fragmentation of its innovation systems. The present Thai government aspires to apply the concept to promote both high-tech manufacturing clusters, services clusters and community-based clusters at the grass-root level. This paper analyses three very different clusters in terms of technological sophistication and business objectives, i.e., hard disk drive, software and chili paste. It portrays their significant actors, the extent of interaction among them and the evolution of the clusters. Though are very dissimilar, common characteristics attributed to qualified success are found. Main driving forces of the three clusters are cluster intermediaries. Forms of these organizations are different from a government research and technology organization (RTO), an industrial association, to a self-organised community-based organization. However, they perform similar functions of stimulating information and knowledge sharing, and building trust among participating firms/individuals in the clusters. Literature in the cluster studies argues that government policies need to be cluster specific. In this case, the best way to design and implement cluster-specific policies is through working closely with intermediaries and strengthening their institutional especially in linking member firms/individuals to other actors in clusters such as universities, government R&D institutes, and financial institutions.

The importance of online communication is getting increased by the rapid growth of smartphone supply and Social Network Service (SNS) use. Catching up with the trend, firms are actively use SNS to improve brand image, promote products, and communicate with customer. On the one hand, SNS is the channel for firms' marketing activities, but on the other, it is also the channel where the events related to the firms propagate in real time. Firms are led to unexpected state of crisis, when events are quickly spread out on SNS. Then firms are assessed their image by the way they deal with the state of crisis. This paper proposes to figure out user response on SNS according to each crisis response strategies by analyzing event-related twitter data when crisis situations of firms arise. We classify crisis response strategies into response attitude, defensive and accommodative response, and response speed, fast and slow response. This paper suggests optimal crisis response strategy to firms regarding state of crisis propagated on SNS.

This study investigates the characteristics and implications of the newly emerging socially-oriented innovation policy. The socially-oriented innovation policy has systemic views on the evolution of socio-technical system and innovation policy. It's ultimate goal is the transition toward sustainable socio-technical system and it takes "strategic niche management" approach for the transition policy. The governance structure of the policy is more open to the public actors, such as social service organizations and public institutes. As a case study, "the Technology-based Policy for the Enhancement of Quality of Life", which is the first comprehensive socially-oriented policy of Korea, is examined and it is suggested that the policy has some limitations because of the path dependency of targeting-oriented and catching-up style innovation policy of Korea.

Light olefins are important petrochemicals as well as primary building blocks for various chemical intermediates. As the number of ethane cracking center (ECC) process, in which ethylene accounts for most of the production, has increased in recent years, propylene supply is not catching up with steadily increasing propylene demand. This trend makes the conversion of methanol to olefins to get more industrial importance. The methanol to olefins (MTO) process produces methanol through syngas and obtain olefins such as propylene through methanol. Since the reaction from methanol to olefins provides different product compositions depending on the catalyst used for the reaction, it is important to choose an appropriate separation process for the reaction product with different composition. Four different separation processes are considered for four representative cases of product compositions. The separation processes for the reaction products are evaluated by techno-economic analysis based on the simulation results using Aspen plus. Guidelines are provided for selecting a suitable separation process for each of representative case of product compositions in the MTO process.
