브랜드 확장전략은 고객으로부터 신뢰를 얻은 브랜드자산을 후속상품에 적용시켜 고객의 신뢰를 확산시키려는 마케팅 전략의 일환으로 시장점유를 확보하고 마케팅비용을 감소시키는데 그 목표를 두고 있다. 브랜드 확장전략은 고객의 신뢰를 기반으로 하는 브랜드자산의 구축 및 활용에 초점을 두고 있기 때문에 기본적으로 소비자의 정보처리과정에 대한 탐색이 요구될 뿐만 아니라 아울러, 브랜드 확장의 제반 영향요인들에 대한 이해도 함께 병행되어야 한다. 이러한 관점에서 본 논문은 먼저 고객에 기반한 브랜드자산의 형성요인 및 과정에 대해서 고찰하였으며, 브랜드확장 전략의 기존 연구들을 통합된 모형을 통해서 개략적으로 제시하였고, 브랜드확장의 적합성에 초점을 맞춘 연구와 브랜드확장의 영향요인에 초점을 맞춘 연구로 분류하여 살펴보았으며, 결론적으로 경영관리적 시사점과 앞으로의 연구방향에 대해서 논의하였다. Brand Extension Strategy is one of the marketing strategies to diffuse customer's believes by applying the brand equity obtained from the customer's believes to following offerings and has the goals of possessing market share and decreasing marketing costs. Because that brand Extension Strategy focused on establishing and conjugating the brand equity based on customer's believes, it requires fundamentally not only exploring customer's information processing but also comprehending various factors of brand extension. In this aspect, this paper looks into the factors and processing of brand equity formation based on customers. Using the integrated model from the existing works about brand extension strategy, it surveyed classifying into two streams focused on fitness of brand extension and factors of it. Finally, it proposed some managerial implications and future research.

본 연구는 무연탄으로 활성탄을 제조할 경우 성형이 세공특성에 미치는 효과를 고찰한 것이다. 3가지 다른 방법으로 활성탄(파쇄형 활성탄, 압축성형 활성탄, 압축성형 활성탄)을 제조하여 특성을 비교했다. 이중에서 25%의 콜타르와 7%의 물을 혼합하여 압출 성형한 활성탄이 비표면적, 세공부피, 그리고 경도에서 가장 좋은 물성을 나타내었다. 압축 및 압출 성형체의 표면은 무연탄 원탄과는 달리 무연탄 분말이 바인더와 혼합되어 있으므로 매우 거친 상태를 나타내었고, 활성화시 거칠게 형성되어 있는 입자사이로 활성화제인 수증기가 쉽게 침투하여 많은 세공을 형성시킴을 알 수 있었다. 이렇게 형성된 세공을 통해 수증기 활성화반응이 잘 일어나 직경 3,000-50,000Å 범위의 거대세공이 발달하였다. 파쇄형 활성탄에 비해 약 2배의 거대세공(macropore)부피를 가지고 있었으며 경도도 30%에서 95% 이상으로 상승되었다. This study was to investigate the effect of granulation process on pore characteristics in manufacturing anthracitebased activated carbons. The activated carbons were made by three different methods to compare characteristics: the crushed activated carbon, the compressed activated carbon, and the extruded activated carbon. Among these activated carbons, the extruded activated carbon using a binder that consists of 25% coal tar and 7% water showed the best characteristics in specific surface area, pore volume, and hardness. Since the compressed and the extruded substances had coarser surfaces than a raw material, steam could penetrate easily through particles and produce macropores especially in the diameter ranges of 3,000-50,000Å during activation process. The extruded activated carbon showed about twice more macropore volumes than the crushed activated carbon and the hardness was increased from 30% up to 95%.

Activated carbons were prepared from Korean coal by steam activation in this study. The variation of pore structure of the activated carbons were investigated according to different carbonization temperatures. Yield, surface area, pore volume and pore structure of this activated carbon were compared with those of activated carbon prepared without carbonization. The investigated carbonization temperature ranged from 700℃ to 1,000℃. Carbonization was carried out in nitrogen atmosphere for 70 minutes and activation was performed by steam at 950℃ for 210 minutes. Surface area and pore volume of the resulting activated carbons increased with carbonization temperature. Also pore volume increased by 20% compared to the activated carbon without carbonization. Especially, in mesopore region, the activated carbon carbonized at 900℃ had more pores by 60% than that of activated carbon carbonized at other temperature.

The purpose of this study is to investigate the variation of pore size distribution of the coal-based extruded activated carbon. The extruded activated carbon was prepared by extruding the mixture of coal powder and coal tar. Pore size distribution of the extruded activated carbon was compared with that of the extruded coal and the extruded char. Also it was compared with that of the crushed activated carbon, raw coal and char. The extruded coal had coarser surface than that of raw coal. Macropores of the extruded coal were funned near 10,000Å in diameter during carbonization process and steam penetrated easily between particles and were growing between 3,000Å and 20,000Å in diameter during activation process.
