A relationship between sea level variations in the Korea Strait (the western and the eastern channels) and the Tokara Strait in the Kuroshio region is examined using daily-mean sea level data from 1966 to 1986. The seasonal variation of the sea level difference (SLD) between Izuhara and Pusan (the western channel) is most periodic: the positive anomalies appear from summer to autumn, and the negative anomalies from winter to spring year to year, whereas SLDs neither between Hakata and Izuhara (the eastern channel) nor between Naze and Nishinoomote (the Tokara Strait) show such a periodic variation. Much similarity has been found between SLDs in the eastern channel and the Tokara Strait, and in particular they were closely correlated in a special event of the Kuroshio region, such as a large meander of the Kuroshio. This paper shows that the periodic seasonal variation of the SLDs in the western channel should be less related to the Kuroshio region. This result also implies that the variation of SLD in the western channel is largely influenced by local factors, such as the bottom cold water in the western channel in summer, rather than from the Kuroshio region.

Bulk amorphous alloys with reasonable glass forming ability and large plasticity were found in Zr-Cu-Al alloys. Further increase in the GFA and the ductility is expected by appropriately choosing a fourth element. In this study, we select Be as the fourth element and added to the Zr-Cu-Al system to synthesize $(Zr_{57.4}Cu_{38.1}Al_{4.5})_{100-x}Be_x$(x=0~16) alloys and the glass forming ability and the plasticity were measured. With Be addition, the supercooled liquid region (${\Delta}T_x$), the plasticity and GFA as high as $134^{\circ}C$, 20.5%, 7 mm, respectively, can be obtained. Herein, we present the effect of Be addition on the variations of various mechanical properties and thermal characteristics of the $(Zr_{57.4}Cu_{38.1}Al_{4.5})_{100-x}Be_x$ alloys.

Over the past few decades, globalization has been shifting economic power upward to transnational actors on the one hand, and downward to subnational or regional spaces on the other. This phenomenon has resulted in the centrality of territorially delimited subnational regions acting as critical loci of economic governance within a complex and globally distributed value chain of trade and service flows. Within this broader context of industrial restructuring are economic regions that span national borders in their collective assets. The paper focuses on investigating the economic competitiveness and productivity of cross-border (or binational) economic regions. Using the conceptual framework of economic clusters, an econometric model that measures proxies of geographic proximity of firms in the life sciences cluster, and a new binational economic model, the paper examines the key characteristics, potentials and constraints of economic competitiveness and productivity in a cross-border region comprising counties in Western New York and regional municipalities in Southern Ontario. The findings demonstrate the direct and indirect benefits of closer cross-border economic cooperation. The paper then concludes with some policy observations about leveraging cross-border economic clusters for strategic industrial cooperation.

This study was performed to investigate the growth and photosynthetic rate of ten-years old Pinus koraiensis and Pinus rigida in Banwol industrial region comparing with those of the control site in Gwangju, Gyeonggi Province. Surface soil of the damaged site in pH 4.2 was more acidic than control site in pH 4.8, assuming the accelerated soil deterioration by acid deposition. The shoot growth, needle survival rate and net photosynthetic rate of P. koraiensis and P. rigida at the damaged site were lower than at the control site. In addition, the quantum yield and chlorophyll a+b and b contents reduced in damaged treatment. These results suggest that an inhibition of photochemical reaction of P. koraiensis and P. rigida at the damaged site of Banwol industrial region could be attributed to combined influence of atmospheric pollution and soil acidification.

The purpose of this paper is to analyses current status and issues of cluster formation and extract policy implications. To this end, the questionnaire which surveyed the level of cluster formation were executed targeting the actors of regional innovation projects(RIPs). The results show that the situations and development stage of the cluster formation between capital region and non-capital region, large cities and small and medium sized cites are different. The level of clustering is also satisfactory, which is a requirement for cluster formation at its early stage. However, the capacity for phase II of cluster growth is not sufficient yet in terns of relationships between ventures and large corporations, institutions supporting management, finance and marketing, researchers from each individual sector of strategic industries and spin-off fines. Therefore, RIPs should be promoted with different policy tools for various regions that are devised according to the varying development stage of each region. The location of RIPs should be determined considering efficiency rather than equity, clustering rather than decentralization, and specialization rather than multiple development. In the long term, developed regions should pursue balanced regional development, with underdeveloped regions targeting specialization.

This study analyzed intra-regional disparities by using the concentration index of industrial organization theory. And the range of study is 11 cities in Chungcheongbuk-do province. This study aims to clarify the characteristics of the intra-regional disparities by using concentration ratio(CR) and Herfindahl-Hirschman Index. After the review of previous studies, we intend to study the intra-regional disparities using these two indexes. Target is the bio-health industry that all povinces in South Korea want to develop competitively. In addition the analysis was conducted by dividing the bio-health industry into four detailed fields(pharmaceuticals, medical devices, health functional foods, and cosmetics). These fields are based on the results of the city and county competitiveness-enhancing industry. The research results derived the intra-regional disparities index based on sales, the number of workers, and R&D expenses by detailed field. As a result it was confirmed that the strengths according to the detailed fields differed by region. It can be used as basic data in establishing differentiated industrial development strategies for each region in the future.

Response surface methodology(RSM) is a very useful statistical techniques for improving and optimizing the product process. By this reason, RSM has been utilized extensively in the industrial world, particularly in the circumstances where several product variables potentially influence some quality characteristic of the product. In order to estimate the optimal condition of product variables, an experiment is being conducted defining appropriate experimental region. However, this experimental region can vary with the experimental circumstances and choice of a researcher. Response surface designs can be classified, according to the shape of the experimental region, into spherical and cuboidal. In the spherical case, the design is either rotatable or very near-rotatable. The central composite design(CCD)s widely used in RSM is an example of 5-level and spherical design. The cuboidal CCDs(CCDs with ${\alpha}=1$) is appropriate when an experimental region is cuboidal but this design dose not satisfy the rotatability as it is not spherical. Practically, a 3-level spherical design is often required in the industrial world where various level of experiments are not available. Box-Behnken design(BBD)s are a most popular 3-level spherical designs for fitting second-order response surfaces and satisfy the rotatability but the experimental region does not vary with the number of variables. The new experimental design with expanded experimental region can be considered if the predicting response at the extremes are interested. This paper proposes a new 3-level spherical RSM which are constructed to expand the experimental region together with number of product variables.
