The recently developed and operated Busan air cruise cable car has become a successful positioning and an interesting target in terms of tourism resources and revitalization of the local economy. The purpose of this study is to investigate how the experiential elements based on Pine & Gilmore’s experience economy apply to the cable car. And the study also examined the effect of experiential elements on the satisfaction and revisit intention. For the purpose of empirical study, the visitors to the cable car were surveyed. Firstly, the results showed that aesthetic experience has a significantly positive effect on satisfaction. Entertainment experience, escapism experience and education experience don‘t affect satisfaction. Second, satisfaction has a positive effect on revisit intention, indicating that the more satisfied the customer is with experiential elements, the more likely the customer is to revisit it.

유미옥,천재우,오계헌 순천향대학교 기초과학연구소 2004 순천향자연과학연구 논문집 Vol.10 No.2

The aim of this work was to investigate the killing effect of the food-poisoning bacterium, Listeria monocytogenes exposed by tea polyphenol (TPP) extracted from green tea. The stress shock proteins, which contribute to the resistance of the cytotoxic effect of TPP, were induced at different TPP concentration in exponentially growing cultures of L. monocygenes. This response involved the induction of a 70-kDa DnaK and a 60-kDa GroEL monoclonal antibodies, characterized by SDS-PAGE and Western blot by the use of the anti-DanK and anti-GroEL monoclonal antibodies. Survival of L.monocytogenes with time in the presence of different concentrations of TPP was monitored, and viable counts paralleled the induction of the stress shock proteins in this strain. This strain killed in the concentration of 1,000㎍/㎖ TPP within 4 hours of incubation. Scanning electron microscopy for the cells treated with 1,000㎍/㎖ for 12 hours showed the presence of perforations and irregular rod shaped with wrinkled surfaces.

유미옥,천재우,오계헌,Yu Mi-Ok,Chun Jae-Woo,Oh Kye-Heon 한국미생물학회 2004 미생물학회지 Vol.40 No.4

본 연구는 차 카테킨인 EGCG (epigallocatechin gallate)에 의한 구강세균의 살균효과를 조사하기 위하여 수행되었다. 초기 세포밀도 $10^{7}$ cell/ml의 대상 세균에 대한 항세균 활성은 EGCG 1ml당 5mg에서 조사하였다. 선택 또는 복합배지상에서 집락생성단위(colony-forming unit, CFU)에 근거하여 EGCG의 항세균 활성은 농도에 비례하는 것을 확인하였다. Streptococcus mutans와 Streptococcus sobrinus는 5mg/ml의 EGCG에서 8시간 이내에 완전히 살균되었다. Lactobacillus acidophilus와 Lactobacillus plantarum도 동일한 조건에서 각각 2시간과 4시간 이내에 살균되었다. 2.5 mg/ml의 EGCG로 처리한 사람의 타액에서 유래하는 총 구강세균의 생존율을 BHI 고체배지상에서 조사하였으며, 총 구강세균은 10시간 이내에 완전히 살균되었다. MS 고체배지상에서 S. mitis and S. salivarius의 집락은 감소되었으며 배양 12시간 이내에서는 집락은 관찰되지 않았다. 그 결과, EGCG는 입냄새와 치석의 원인이 되는 구강세균을 살균시키고 충치를 예방하는 자연적이며 효과적인 물질임이 입증되었다. The purpose of this work was to investigate the effect oftea catechin, epigallocatechin gallate (EGCG) on killing of oral bacteria. The antibacterial activity of 2.5 mg/ml and 5.0 mg/ml EGCG was investigated for target bacteria of which initial cell number was approximately adjusted to $10^{7}ml$. The antibacterial activity of EGCG was proportional to the concentration according to colony-forming unit(CFU) of target bacteria enumerating on selective and complex media. Streptococcus mutans and Streptococcus sobrinus at 5mg/ml EGCG were completely killed within 8 hrs. Lactobacillus plantarum and Lactobacillus acidophilus were also killed within 2 hrs and 4 hrs under the same conditions, respectively. Oral bacteria at 2.5 mg/ml EGCG were completely killed within 10 hr. Colony numvers of S. mitis and S. salivarius treated with 2.5 mg/ml EGCG were decreased on MS solid media and no colony was observed on the media within 12 hrs. In consequence, EGCG would be a natural and effective compound that kill oral bacteria being caused of bad breath, plaque and gingivitis, and for preventing and treating dental caries.

유미옥,정원준 한국일러스아트학회 2016 조형미디어학 Vol.19 No.1

Chinese enterprises are building up their symbolic identity which is creative and discriminatory through various methods in order to emphasize the identity of the enterprise image inside the global market. Especially, they are very interested in the enterprise symbol mark. Symbol mark should be combined with the design that the times demand and the creation of the forms that are easy to identify in order to improve the conveyance of the brand image. Therefore, this paper is expected to be the basic theoretical materials which can be more upgraded in the establishment of the Chinese enterprises’ identity by analyzing in detail the Chinese brand symbol marks taking the enterprises which Inter-brand, which is a famous American global brand consulting enterprise, selected as Chinese typical enterprises as subjects. In this study, two methods are adopted in the analysis. First of all, 50 Chinese enterprise brands’ symbol marks were selected and the meaning that the current situation of the types of business and the symbol symbolize were analyzed according to the contents. For the formative analysis, five categories were divided. They are type, form, color, expressive factor, the application of traditional image. Secondly, the analysis results of these 5 categories related to Chinese brand symbol mark were compared with Korean 50 brands of 2014 which ere divided into five categories with the same method and the results were drawn up. In terms of Chinese symbol mark design, there were many symbols that emphasize the organic combination with the historical tradition and the modern times. There were changes and reconstruction of Chinese traditional cultural factors that contain symbolic meaning and the typical factors of the modern times. People’s demand for beauty is increasing day by day, so the enterprises should occupy the competitive advantage of the brand by combining the aesthetic sense and brand characteristics. 중국의 기업은 최근 글로벌한 시장 속에서 기업이미지의 정체성을 강조하기 위해 다양한 방법으로 독창적이고 차별성이 강한 상징적 아이덴티티 정립을 내세우고 있다. 그 중에서도 특히 기업 심벌마크에 대한 관심이 매우 높다고 할 수 있다. 심벌마크가 브랜드 이미지 전달의 인상을 높이기 위해서는 순간 식별이 가능한 형태의 제작과 함께 시대가 요구하는 디자인을 접목시켜야 한다. 이에 본 연구는 미국의 저명 글로벌 브랜드 컨설팅 업체인 인터브랜드가 선정한 중국의 대표기업을 중심으로 중국의 브랜드 심벌마크에 대한 구체적인 분석을 함으로써 앞으로 중국기업의 아이덴티티 정립에 한층 더 업그레이드 될 수 있는 이론적 기초자료가 될 수 있으리라 사료된다. 본 연구에서는 2가지 방법에 의한 분석을 하였다. 먼저, 중국의 50개 기업브랜드 심벌마크를 선정하여 심벌마크에 대한 업종별 현황 및 심벌이 상징하고 있는 의미에 대한 내용별 분석을 하였으며, 조형적 분석을 하기 위해 5가지 방법에 의한 분류 즉, 유형별, 형태별, 색채, 표현요소, 전통이미지 활용에 의한 분석을 하였다. 두 번째로 중국의 브랜드 심벌마크에 의한 5가지 분석결과를 같은 방법으로 분류한 2014 한국의 50개 브랜드와 함께 비교 적용하여 그 결과를 도출하였다. 분석 결과, 현재 중국 브랜드 심벌마크의 디자인이 얼마만큼 효과적으로 적용되었는지 알아볼 수 있으며, 심벌마크를 상징하는 중국의 브랜드 문화와 특징을 살펴볼 수 있었다. 중국의 심벌마크 디자인에는 역사적 전통과 현대의 유기적인 결합을 강조하는 심벌들이 많이 분포 되어 있으며, 현대의 대표적인 요소들과 함께 상징적 의의가 있는 중국 전통문화 요소의 변화와 재구성을 하여 전통적인 형상과 풍미가 있는 동시에 현대적 디자인의 의미가 내재되어 있음을 알 수 있었다.
