The main purpose of collecting and analyzing operating experience events is to look for insights to improve safety. The underlying assumption is the correlation and causality between events with different safety significances. The analysis of this assumption could be valuable to optimize operating experience feedback programs and to enhance safety. This paper analyses the correlation between events with different safety significances. Groups of events from six nuclear energy related databases are considered. The findings are that a correlation exists but with various levels and not as large or consistent as might be expected across different databases. These results might be the basis for further work to analysis causality, to find out how a similarity in causes influences the correlation, and finally to improve the operating experience program.

Although shoes industry in Korea is superior in global competition in terms of material, parts, and developmental ability, it has declined due to the lack of design in consideration of OEM production and marketing ability. Shoes industry in Korea has aimed at making inroad to North American market centered with the United States, but it has not focused on Europe market that much. However, as Europe transformed into EU, which is a large economic community, European market is being considered as a great potential for Korean shoes industry, which we can never neglect of. So far, there have been researches of marketing strategic methods to make inroad to the United States and South-East Asian markets, but there has been almost no marketing approach to European shoes market. Therefore, in this study I prepare strategic marketing plans for Korean shoes enterprises to make inroads to European markets, so that they can enter the market successfully, and this is the purpose of this study. In case that Korean shoes industry makes inroads to European market, there are important terms to examine. The strategic terms for consideration to examine are as follows. First, shoes companies such as Nike and Adidas are aware of India. Turkey, and Rumania as new footholds for production, as they have accounted continuous wage claim and labor dispute. Especially Turkey and Rumania are expected to have much competitive strength in price, as they are expected countries for joining EU. Second, we need to shift our understanding of the importance of design for European shoes market. We should pay close attention to the fact that the role of leading companies is to design. Third, Germany, England, and Italy have global-level of specialize institutions and organizations for shoes education and have been succeeded in knowledge industrialization. Fourth, we should consider that the concepts for shoes are changing from innovation in production to in products. Fifth, we should develop specialized concept centered in individualized categories. Sixth, we should open up new markets actively by connecting large shopping centers and multi-shops. Seventh, we should look for the opportunities to expand market through the utilization of BIFOS. Lastly, we should expand our support for opening up markets and participating fairs in foreign countries.

This is a study to review provision and production system of social services in European welfare states and find out implications to Korea. Firstly, trends of social service extension and reorganization in welfare state restructuring process, and approaches in interventions to social service system are theoretically discussed. In this discussion, we focus on the discussion of Jessop's workfare in social service extension and reorganization and the concept of innovation in intervention to social service system by state. Then, In order to look at details of reorganization of social service system through restructuring of European welfare states, German case is reviewed. In this review, the reorganization of social service provision and production system in Germany is analyzed through the comparison with the pre-existing system in terms of relationships with public sector as well as between public and private sector respectively. Finally, implications of the European and German experiences to Korea are explored. In order to do so, the state of social services in Korea is examined whilst comparing to the European development process of social services. Also, pros and cons of the electronic voucher scheme, which transforming the social service provision system in Korea, are discussed then challenges in Korean social service delivery system are discussed.

Gold stock could include the U.K. in the European economy by the alternative plan of the problems that it was occurred while nationalizing industry and a company for economic recovery and national profit after the World War Ⅱ and it was wide and came to open in the country of European most. However, the negation was sentenced to it for the reason of the gold stock which the U.K. adopted in European many countries infringing "freedom of the capital movement" at a European court of law. However, I consider gold stock positively to protect it from hostile M&A of the company of the national strategy from the Middle East and an Asian national rich fund recently in France and Germany. If our country looks straight at reality, Urstatut or the agreement of the majority stockholder have a very strict matter assuming the protection of the existing shareholder and must be able to gain the favor if you look by the flow of such world economy.

As the South Korean rolling stock industry is developing designs for full compliance with the European Standards, it is fitting to take a look at these two core standards. The paper presents an overview of the load cases and structural requirements developed in Europe for the design of safe and compatible rolling stock vehicles. These load cases and structural requirements have been compiled into two standards namely EN12663 and EN15227. Standard EN12663 was developed as a reference design requirements standard. The work was mandated and sponsored by the European Committee for Standardization and Standard issuing National Institutions. EN12663 specifies a series of proof and fatigue load cases for European rolling stock regulations compliant vehicle designs. As EN12663 does not address the crashworthiness issue, a dedicated crashworthiness standard, EN15227, was therefore developed in a similar manner through industry wide consultations managed by a Trans-European working group of experienced engineers and specialists. In both standards, the vehicle and/or trains are grouped into categories reflecting the vehicle types and/or their indented operational function. EN15227, developed to complement EN12663, addresses the "passive" crashworthiness capability of the vehicles and trains. EN15227 specifies reference crash scenarios similar to those found in the Technical Specification for Interoperability (TSI) of high speed trains operating in Europe. The overview also touches on a general comparison with the corresponding British Group Standard (GM/RT2100) and also the UIC leaflet based load cases. The exercise is extended to pertinent design load cases specified by the Federal Railroad Administration (FRA) in the US.

The $Ph{\acute{e}}bus$ FP project is an international reactor safety project. Its main objective is to study the release, transport and retention of fission products in a severe accident of a light water reactor (LWR). The FPT4 test was performed with a fuel debris bed geometry, to look at late phase core degradation and the releases of low volatile fission products and actinides. Post Test Analyses results indicate that releases of noble gases (Xe, Kr) and high-volatile fission products (Cs, I) were nearly complete and comparable to those obtained during $Ph{\acute{e}}bus$ tests performed with a fuel bundle geometry (FPT1, FPT2). Volatile fission products such as Mo, Te, Rb, Sb were released significantly as in previous tests. Ba integral release was greater than that observed during FPT1. Release of Ru was comparable to that observed during FPT1 and FPT2. As in other $Ph{\acute{e}}bus$ tests, the Ru distribution suggests Ru volatilization followed by fast redeposition in the fuelled section. The similar release fraction for all lanthanides and fuel elements suggests the released fuel particles deposited onto the plenum surfaces. A blockage by molten material induced a steam by-pass which may explain some of the low releases. The revaporisation testing under different atmospheres (pure steam, $H_2/N_2$ and steam /$H_2$) and up to $1000^{\circ}C$ was performed on samples from the first upper plenum. These showed high releases of Cs for all the atmospheres tested. However, different kinetics of revaporisation were observed depending on the gas composition and temperature. Besides Cs, significant revaporisations of other elements were observed: e.g. Ag under reducing conditions, Cd and Sn in steam-containing atmospheres. Revaporisation of small amounts of fuel was also observed in pure steam atmosphere.

The processes of regional scales in the East Korean coastal waters were investigated by analysis of the Synthetic Aperture Radar (SAR) images taken by the European Research Satellites ERS-1, ERS-2 and Envisat. More than 500 quick look frames taken in 1991-2003 were examined to detect the frames with clearly surface expressions of oceanic phenomena. 26 ERS-1/2 SAR and 11 Envisat wide swath Advanced SAR (ASAR) frames were selected and obtained from the European Space Agency in a form of the precision high-resolution images. The following oceanic phenomena and processes were evident in the radar imagery through the Korean costal waters: fronts, currents, eddies, internal waves, island and ship wakes, oil pollution, etc. They manifested themselves in the field of sea surface roughness, their scale ranged from several tens meters to about 100 km. The most common morphology of these phenomena was a series of contrast dark or light curvilinear lines and bands. The joint analysis of the discussed SAR images with other satellite and in situ data supported and enhanced our interpretation of SAR signatures.

Although science continues to be a key subject in the education of the majority of young people throughout the world, it is becoming increasingly clear that school science is failing to win the hearts and minds of many of today's younger generation. Researchers have begun to look at ways in which the learning that takes place in museums, science centres and other informal settings can add value to science learning in schools. Four case studies are used to illustrate the potential afforded by informal contexts to research aspects of science learning. The case studies involve: the European Union PENCIL (Permanent European Resource Centre for Informal Learning) project (a network of 14 museums and science centres working with schools to enhance learning in maths and science); a large natural history museum in England; the Tate Modernart gallery in London, and the Outdoor Classroom Action Research Project which involved researchers working in school grounds, field centres and farms. The range of research questions that were asked are examined as are the methodological approaches taken and the methods used to collect and analyse data. Lessons learned from the studies about research in the informal contexts are discussed critically.

Recently, ESA (European Space Agency) has launched CryoSAT-2 for polar ice observations. CryoSAT-2 is equipped with a SIRAL (SAR/interferometric radar altimeter), which is a high spatial resolution radar altimeter. Conventional altimeters cannot measure a precise three-dimensional ground position because of the large footprint diameter, while SIRAL altimeter system accomplishes a precise three-dimensional ground positioning by means of interferometric synthetic aperture radar technique. In this study, we developed an efficient SIRAL SARIn mode processing technique to measure a precise three-dimensional ground position. We first simulated SIRAL SARIn RAW data for the ideal target by assuming the flat Earth and linear flight track, and second accessed the precision of three-dimensional geopositioning achieved by the proposed algorithm. The proposed algorithm consists of 1) azimuth processing that determines the squint angle from Doppler centroid, and 2) range processing that estimates the look angle from interferometric phase. In the ideal case, the precisions of look and squint angles achieved by the proposed algorithm were about -2.0 ${\mu}deg$ and 98.0 ${\mu}deg$, respectively, and the three-dimensional geopositioning accuracy was about 1.23 m, -0.02 m, and -0.30 m in X, Y and Z directions, respectively. This means that the SIRAL SARIn mode processing technique enables to measure the three-dimensional ground position with the precision of several meters.
