  • The key success factors for Franchise Enterprise as a virtual company which is established based on franchise system are the competitiveness of sub-systems in franchise system such as franchisor, franchisee, vendor(supplier), and customer, and to sustain the symbiotic relationship among sub-systems. In this regard, evaluating franchise system is considered to be implemented in different contexts and methods comparing with extant evaluation system in franchise business which is more focused on the relationship between franchisor and franchisee. The flagship role of establishing franchise system is to be franchisor system, however, the symbiotic relationship among other sub-system including franchisee, vendor, and customer leads to successful Franchise Enterprise. The purpose of this study is to research existing evaluation systems for franchise business and to explore the model of evaluating franchise system, what is called, "Symbiosis Index".

  • Mathematical biology has been recognized its importance recently and widely studied in the fields of mathematics, biology, medical sciences, and immunology. Mathematical ecology is an academic field that studies how populations of biological species change as times flows at specific locations in their habitats. It was the earliest form of the research field of mathematical biology and has been providing its basis. This article deals with various form of interactions between two biological species in a common habitat. Mathematical models of predator-prey type, competitive type, and simbiotic type are investigated.

  • 유통시장의 완전한 개방과 더불어 신유통업태의 등장은 기존 재래시장의 경쟁력 약화라는 결과를 초래하였다. 재래시장의 경쟁력 약화는 곧바로 서민경제의 어려움으로 이어지고 이는 지역경제의 붕괴 및 슬럼화라는 악순환을 가져올 수 밖에 없다. 이러한 시점에 재래시장이 갖는 현실적 여건을 살펴보고, 이를 바탕으로 신유통업태와 경쟁관계를 유지할 수 있는 재래시장만의 차별적 운영방안을 제시하고자 한다. 재래시장에 대한 물리적 개선은 단기적 처방에 머물러 장기적인 방향에서 성장을 도모하기는 어렵다고 판단된 것이 본 연구의 출발점이다. 재래시장만의 고유 특성을 극대화하기 위하여 재래시장을 단순한 상거래업체에서 탈피하여 서비스업의 개념으로 경쟁력 강화방안을 도출하였다. 이를 위해 서비스업의 품질을 측정하고 관리하기 위한 이론적 모델중 SERVQUAL을 이용하여 재래시장의 시설 현대화 및 운영프로세스에 대한 실무적 결과를 제시하였다. 결국, 재래시장도 소비자들이 찾고 만족할 수 있는 운영프로세스의 강화가 이루어질 때, 다양한 유통업태들과의 지역내 공생관계를 통한 동반성장이 가능할 것으로 판단된다.

  • Thermodynamic data of mineral reactions were used to construct a phase diagram for the formation of illite from andalusite at one bar and 325${\circ}C$ in the hydrothermal alteration. Based on chemical compositions, the free energy of formation of illite coexisting with andalusite was calculated by assuming the ideal mixing ina bunary system consisting of muscovite and pyrophyllite components. For illite with structural formula $K_{0.86}Al_{2.93}Si_{3.03}O_{10}(OH)_2$, its free energy of formation is -1147.727 kcal/mole at the condition under consideration. The stability area of illite is more narrow than that of end-member muscovite and prefers lower activity of silica. Illite was formed by hydration of andalusite while pyrophyllite decomposed. Illitization took place preferentially at margin and/or along fractures of andalusite.

  • Intergenerational relations in Korea show very unique characteristics. In political arena, young and old generations clash each other intensely, while they maintain a high level of intergenerational solidarity in policy realm. A logistic regression analysis reveals that generational cleavage plays a key role in affecting voting decision and evaluation of governmental performance. It also suggests that in policy realm, normative, functional, and affectional types of solidarity influence people's attitudes on social policies very strongly. If the current government continues to neglect its promises for expanding welfare, the dual structure of generational cleavage in political arena and intergenerational solidarity in social policy realm can soon be turned into a conflictual structure. Therefore, an active initiative to increase intergenerational justice should be taken in order to attain a long-term, sustainable intergenerational solidarity and coexistence.

  • Chloroplasts are believed to be descended from certain cyanobacteria, which were taken up by phagocytosis into a host cell and lived there in a symbiotic relationship. In contrast to the current static concept on the chloroplast genome, its dynamism has been recently demonstrated: the chloroplast genome is active in intramolecular homolgous recombination, producing subgenomic circles when it obtains homolgous sequences via genetic transformation. Chloroplast tranformation in higher plants provides many advantages over nuclear transformation that include higher expression levels of transgenes, polycistronic expression of transgenes, and maternal transmission of transgenes. Tobacco has been used as a model for chloroplast genetic transformation. However, it is recently possible to transform the chloroplasts of other major food and economic crops including rice, soybean, and cotton. Chloroplast-transformed crops will be able to replace bioreactors using microorganisms for production of value-added proteins in future.

  • Pumiceous tuffs occurring in the Beomgockri Group are examined applied-mineralogical characteristics and their controling factors to evaluate their potentials as the adsorption-functional mineral resources. The pumiceous tuffs are diagenetically altered to low-grade zeolitcs and bentonites in the Janggi area. Compositional specialty due to the presence of pumice fragments induces the altered tuffs to exhibit the characteristic adsorption property combined with cation exchange capacity, specific surface area, and acidic pH. Unusual lower pH in the adsorption-functional mineral substances is turned out to be originated from the presence of H-smectite having $H^+$ in the interlayer site of the sheet structure. On account of disordered crystallinity resulting from the exchanged $H^+$ in the interlayer site, the smectite commonly forms crenulated edges in the planar crystal form and exhibits characteristic X-ray diffraction patterns showing comparatively lower intensities of basal spacings including (001) peak than conventional Ca-smectite. Based on the interpretation of paragenetic relations and precursor of the H-smectite, a genetic model of the peculiar clay mineral was proposed. The smectite formation may be facilitated resulting from the precipitation of opal-CT at decreasing pH condition caused by the release of H+ during diagenetic alteration of pumice fragments. Because of the acidic smectite, the low-grade mineral resources from the Beomgockri Group may be applicable to the adsorption industry as the raw materials of acid clays and bed-soil.

  • CSV(Creating Shared Value) model was proposed by Porter and Kramer (2011) to address relationship between businesses and society. Namely, it means that CSV deals with business value and social problem solving simultaneously. In this paper, the notion of CSV was applied to the food enterprise, and the cases of CSV with farming area were discovered. Especially, this paper proposed the framework for analyzing CSV activity based on the three-level of CSV suggested by Porter and Kramer (2011) and strategic options for vertical coordination proposed by Peterson et al. (2001). As a result of case analysis applying the proposed framework in this study, three types of CSV activity were discovered: Local food type, downstream support type, and joint corporate establish type. Local food type creates CSV based on momentary purchase or specification contract as strategic options for vertical coordination. Downstream support type creates CSV mainly based on relation-based alliance as a strategic option for vertical coordination. Lastly, joint corporate establish type creates CSV based on equity-based alliance as a strategic option for vertical coordination. This paper contributed to the CSV literatures for discovering cases of CSV with farming area and categorizing discovered cases applying proposed framework.

  • This study assesses the strategy and performance of Eco-industrial Park (EIP) initiative implemented by Korea Industrial Complex Corporation (KICOX) with the support of Ministry of Trade, Industry and Energy (MOTIE), Korea since 2005 to 2013 and recommends future directions. After the concept of EIP based on industrial symbiosis (IS) is introduced, the background and implementation procedure of the EIP initiative are described. Then, economic and environmental achievement was assessed. During the project periods (2005-2013), 449 industrial symbiosis project were explored, among which 296 projects have been implemented. Among (Of these 296 projects,) them, 244 projects have been completed in which 118 projects have been commercialized which shows 48% commercialization rate of the completed projects. Through these commercialized projects, around 311.1 billion won/year of economic benefits and reduction of waste by-products of 828,113 tons/year, wastewater of 215,517 tons/year, reduction in energy consumption of 250,475 toe/year and GHG emission reduction of 1,107,189 $tCO_2/year$ were achieved. This results confirmed that EIP initiative based on industrial symbiosis can enhance eco-efficiency of industrial parks and harmonize economy and environment. However, there are obstacles like absence of interagency coordination and cooperation, laws and institutional barriers, increased demand for local governments, funding for project investment. Thus, to utilize EIP initiative as a strategic tool for competiveness and environmental management of industrial parks, it needs intergovernmental collaboration and interdisciplinary approach to lower barrier in implementation.

  • The Geodo mine area, had been developed for Fe and Cu ores since 1963 and abandoned in recent decades, is located in the central part of the Taebaeksan mineralized district. This area comprises of the Jangsan, Myobong, Pungchon, Hwajeol, Dongjeom, and Dumugol Formations in ascending stratigraphic order. These Formations were intruded by the Cretaceous Eopyeong granitoids that appears to produce the Geodo skarn. Their compositions are relatively oxidized quartz monzodiorite to granodiorite (magnetite series, $Fe_2O_3/FeO=0.3{\sim}1.1$). Mineralizations related skarn deposit occur in the Myobong, Pungchon, and Hwajeol Formations. The proximal skarn is zoned from andraditic garnet ($Ad_{44-95}Gr_{1-53}$) predominant adjacent to the Eopyeong granitoids to diopsidic pyroxene ($Hd_{10-100}Di_{0-89}$) predominant away from the one. The differential proportion of garnet and pyroxene is generated by water/rock ratio and their source, such as magmatic and meteoric water. This is useful tool for assessment the overall oxidation state of the entire skarn system. Gold occurs in proximal red to brownish garnet skarn, and genetically associated with Bi- and Te-bearing minerals. Skarn deposit developed in the Geodo mine area is considered as oxidized Au skarn category, based on chemical composition of the Eopyeong granitoids, zonation of skarn, and gold occurrences. Garnet-rich skarn zone will be the main target for exploration of gold in the study area. However, it is needed to the detailed survey on vertical zonation of this area as well as lateral zonation. The result of this survey would provide an important basis for the exploration of the skarn Au deposit in the Geodo mine area.
