최근 대승인터컴의 얼짱 프렌차이즈 사업이 큰 주목을 받고 있다. 스티커자판기 매장을 '얼짱'이라는 브랜드로 체인화한 이 사업은 전반적인 프렌차이즈 시장 불황에도 불구하고 좋은 반응을 얻고 있다. 지금까지 오픈 된 매장만 해도 20여개에 이르고 후속매장의 오픈도 속속 예정되어 있다. 이대로의 기세라면 제2의 스티커자판기 전성시대를 노릴 만도 해 보인다. 디카 폰카 전성시대에 한물 간 듯한 스티커자판기가 어떻게 유망사업으로 화려한 컴백을 진행하고 있는 지, 그 비결이 궁금하지 않을 수 없다. 대승인터컴이 펼치는 얼짱 프렌차이즈 사업의 노하우를 직접 확인하기 위해 현장으로 달려 나가 봤다

영등포역에서 전철로 동대문까지 출퇴근을 하는 이모씨(35). 그에게 최근 새로운 출퇴근 취미하나가 생겼다. 영등포 역사 내 설치된 책자판기에서 책을 한권씩 구입해 출퇴근 시 독서하는 재미에 맛을 들인 것. 핸드북은 양복 안주머니에 쏙 들어가는 싸이즈로 휴대하기도 편할 뿐만 아니라 가격도 2000원으로 저렴하다. 또 분량이 많지 않아 집중해 읽다보면 하루에 한권을 다 읽는 경우도 있다. 이렇게 읽다보니 독서량이 상당해 졌다. 책자판기를 생각하면 은근히 하루가 기다려지는 이모씨. 내일은 과연 무슨 책이 구비되어 있을 까? 한 가지 바람이 있다면 좀더 다양한 콘텐츠의 도서들이 판매되었으면 하는 점이다.

A thousands of chairs have designed from the Victorian era to the present. Thonet's Nol4 chair in 1859, Wright's high-back chair in 1904, Ritveld's red/blue chair in 1917, Breuer's Wassily chair in 1925, Aalto's Paimio chair in 1932, Eames's DAR chair in 1948, Piero Gatti's Sacco chair in 1969, Starck's Von Volgelsang chair in 1984, Stumpf's Aeron Chair in 1992, Little's 'Coat of arms' chair in 1994 - the list of architects who have seized the opportunity to express their theories in the design of a chair is seemingly endless. Architects such as Machintosh(1868-1928), Wright(1807-1959), Aalto(1898-1976) included chairs within their artistic schemes for interiors and buildings. But as the manufacture of chairs moved away from the domain of the craftsman towards that of the industrial process, architects were also ideally positioned, with their background knowledge of engineering, to pioneer innovative chair design within the constraints of modern manufacturing technology. Beyond matters of function and structure, the fundamental worth of chairs, past or present, lies in their communication of attitudes, ideas and values. The persuasiveness of a chair depend on the clarity of its rhetoric. Chair has become an ideal medium for designers to make their visual statements and construct their individual manifestos. In chair design there is a ping-pong game played out between absurd and useful design, and this game is one way in which the design profession explores itself.

The purpose of this study is to develop a method for separating antioxidants and sugars from grape skin extract. The extract was first mixed with a variety of organic solvents to investigate whether the separation was feasible. When employing acetone, ethanol, dimethylsulfoxide, or dimethylformamide, the organic solvent-extract combination formed a single phase. However, when benzene, ethyl acetate, or n-hexane was added to the extract, the mixture separated into an organic and an aqueous phase and the pigments remained in the aqueous phase. On the other hand, when polyethylene glycol-2,000 (PEG-2000) and sodium citrate were added to the extract, the mixture was separated into three layers, with the majority of the flavonoids migrating to the top layer and 53% of the extract's glucose migrating to the bottom layer. The top layer had significant antioxidant activity, whereas the bottom layer showed no antioxidant activity. The glucose recovery in the bottom layer increased as the molecular weight of PEG increased and the highest recovery (67%) was observed when PEG-8,000 was added. The highest flavonoid separation was observed with PEG-2,000, followed by PEG-8,000 and PEG-400. The flavonoid separation when PEG-2,000 was added resulted in a flavonoid recovery of 48% and 0.2% from the top and bottom layers, respectively. Examining the effect of the separated solution using the agar disc diffusion method on yeast cell growth confirmed that the addition of the extract, the top, and the bottom layer did not inhibit cell growth.
