The Korea's West Coast has been considered as the gateway to the economies of Southeast Asia and China. Thanks to geographical advantages, harbors located in this region have been playing a vital role despite the fact that most harbors in this region are the small and medium ones. The GunJangHang is such harbor. This paper aims to investigate the important role of this harbor, as well as to analyze the competitiveness of GunJangHang port with those of the luncheon phosphorus port, Pyongteak port, and Mokpo port regarding the rapid increasing cargo volume through this region recently.

본 연구는 지식기반 경제에서 지역경제발전을 위해 더욱 중요시되는 혁신과정에서의 경쟁과 협력의 의미를 살펴보았다. 경쟁이 기업의 경쟁우위를 유지하는 데 중요하지만 지역의 혁신역량이 촉진되기 위해서는 기업을 포함한 혁신주체간의 협력이 필요하였다. 경쟁적 환경에서 학습과 혁신이 지속적으로 개발되기 위해서 협력관계에는 신뢰와 안정성이 수반되어야 하며, 야기되는 상호적 학습과정에서 공간적 인접성이 긍정적 효과를 줄 수 있음을 파악하였다. 혁신에 중요한 암묵적 지식이 효과적으로 교환되는 네트워크가 지역 내에 구축되어야 하는 근거도 논의하였다. 끝으로 낙후된 지역에서 혁신을 위한 협력관계의 네트워크가 가능한 지를 조사하고, 그에 따라 이 지역에서 성공적인 지역혁신체계가 수립되기 위한 정책적 의미를 제시하였다.

In "Creating the Technopolis: High Technology Development in Austin Texas," Smilor, Kozmetsky, and Gibson (1988) make the case that in the mid-1980s Austin was becoming a globally competitive high tech region. Indeed over the years and into 2013, Austin has established its reputation as a leading entrepreneurial and technology center and "talent magnet." Delegations from across the US and worldwide visit Austin to better understand how this central Texas city went from being a state government and university town to become a fast growing, globally competitive, technology hotspot leading the state and nation in job creation. Central to the concept of the Triple Helix and Technopolis Frameworks is the importance of university, business, and government cooperation. This paper gives examples of mechanisms, processes, and metrics on how The University of Texas at Austin; regional technology industry; federal, state, and local government policies; and support groups all contributed to growing and sustaining the Austin Technopolis.

Existence of a binding site for choline esters with an acyl chain of various sizes was examined by comparing the inhibitory potency of the respective compound. In contrast to acetylcholine, which showed a pure competitive pattern of inhibition, choline esters with an acyl chain of a long size ($C{\geq}5$) expressed a mixed type of inhibition. Binding of choline esters containing a long chain ($C_7-C_{12}$) to the hydrophobic region in the active site is deduced from a linear relationship between the $K_{iE}$ value and the size of acyl moiety, and a good hydrophobicity relationship. In addition, the non-competitive component in the inhibition of acetylcholinesterase seems to be due to the interaction of choline esters with both the hydrophobic site and the trimethylammonium-binding site in the active center of the acetylated acetylcholinesterase.

In order to obtain the more effective evidence, supporting the hypothesis which have been previously described by former report that pepsin (EC 3.4. 4.1) forms a hydrophobic bond with the nonpolar side chain of its substrate, the inhibitory effect of carboxylic acids(from formic acid to iso-butyric acid) on the activity of pepsin to the synthetic dipeptide, N-Carbobenzoxy-L-glutamyl-L-tyrosine, was discussed. The kinetic study showed that the inhibition by carboxylic acids was competitive. The Kidecreased with increasing size of the inhibitor molecule. The $-{\Delta}F^{\circ}$increased linearly with increasing number of carbon atoms in the hydrocarbon chain of the inhibitor. It was confirmed that the hydrophobic bond between more than one side chain of amino acid residues(phenylalanine) in the binding region of the active center of pepsin and the side chain of amino acid residues in the substrate was formed as the first step of its enzymic mechanism. The inhibitory effect of carboxylic acids was due to the competition of the hydrocarbon group of the carboxylic acids with the side chain of the substrate for the hydrophobic binding site(the side chain of phenylalanine) of the pepsin.

Recently, many researchers have been interested in biometric systems such as fingerprint, handwriting, key-stroke patterns and human iris. From the viewpoint of reliability and robustness, iris recognition is the most attractive biometric system. Moreover, the iris recognition system is a comfortable biometric system, since the video image of an eye can be taken at a distance. In this paper, we discuss human iris recognition, which is based on accurate iris localization, robust feature extraction, and Neural Network classification. The iris region is accurately localized in the eye image using a multiresolution active snake model. For the feature representation, the localized iris image is decomposed using wavelet transform based on dyadic Haar wavelet. Experimental results show the usefulness of wavelet transform in comparison to conventional Gabor transform. In addition, we present a new method for setting initial weight vectors in competitive learning. The proposed initialization method yields better accuracy than the conventional method.

본고는 광양항의 수출경쟁력을 분석하기 위해 변이할당분석, 국별비교우위(열위)지수, 불변시장점유율분석을 함께 이용한다. 먼저 광양항의 주요 수출품목인 HS 39, 72, 28, 29의 국별비교우위지수를 도출하여 광양항이 중국에 대해 HS 39, 28에서는 비교우위를, HS 72에서는 비교열위를, HS 29에 대해서는 불안정한 우위가 있다는 것과 4개 품목 모두에서 비교우위정도가 계속해서 감소하고 있다는 것을 보인다. 국별비교열위지수를 이용하여 중국이 수입시장에서 다른 품목들에 비해 4개 품목에 대해 비교우위를 가지나 비교우위정도가 점차 감소하고 있다는 것도 밝힌다. 불변시장점유율 분석을 통해 중국의 수입구조는 불리하게 작용하는데 반해 중국의 수입규모효과는 모두 유리하게 작용한다는 것과 경쟁력효과는 HS 39와 29에는 불리하게 작용하나 HS 28과 72에는 유리하게 작용함을 보인다. 변이할당분석을 통해 4개 품목 모두 항만의 혜택을 받지 못하며, HS 28은 산업구조효과와 지역경쟁력이 긍정적이나, HS 72는 지역의 경쟁력은 있으나 산업구조가 불리하며, HS 39는 산업구조는 유리하나 지역경쟁력이 떨어지고, HS 29는 불리한 산업구조는 물론 경쟁력도 약함을 밝힌다.

Purpose: The companies must be located in the area, scale up, create jobs, and return to the local economy. This paper attempted to analyze empirically the relationship between regional context and entrepreneurial orientation(EO) in the region of Korea. Methods: This paper analyzed survey data and regional statistics. We measured EO by region and then examined which regional context affect EO. Regional contexts were measured by population, economic size, budget size, firm size, innovation capacity, and education level. EO was measured by innovativeness, risk taking, proactiveness, autonomy, competitive aggressiveness, and need for achievement. Results: EO was high in the region where the budget size per thousand population, the number of manufacturers per thousand population, the number of new corporations per thousand population, the number of R&D personnel per thousand population, and the number of students of higher education institutions per thousand population were high. Conclusion: The implications of this paper are that regional context affect EO, and there are differences in budget scale, firm size, innovation capacity, and education level. In regions with many investment resources for innovation and startups and manufacturers, the number of R&D personnel and students of higher education institutions (future R&D personnel), in particular, determines EO.

This Paper deals with the development of Incheon International Airports and Pusan and Kwangyang Ports as Hub Ports in order to systemize nationwide logistics networks. Now, Korea has core competences in terms of social overhead capital, telecommunication, information technologies, all fields of manufacturing plants, and the other infra-structure. As the environments of North-East Asian countries changes dynamically, at least we should keep up with the situations which require to meet the globalized level of international logistics services in Pusan and Kwangyang Ports to be a competitive Hub Ports in this region.
