생물 종 다양성 및 보존에 대한 필요성은 곤충과 같은 생물 개체의 정확하고 효율적인 인식 방법에 관심을 불러 일으켰다. 특히 스마트 폰과 같은 디지털 정보가전의 발달과 보급으로 인해 영상 매체를 이용한 곤충 종의 자동인식에 대해 많은 연구가 이루어지고 있다. 본 논문은 나비 영상 인식을 위해 가지 길이 유사성 엔트로피(Branch Length Similarity Entropy)를 이용한 특징 추출 방법을 제안한다. 제안한 특징 추출 방법은 나비의 윤곽으로부터 높은 곡률을 가진 특징점들을 추출한 다음 이들 사이를 네트워크로 구성하고 특징점 간의 길이 분포를 엔트로피로 표현한 것이다. 제안한 특징 추출 방법의 성능을 평가하고자 15종의 나비 영상을 대상으로 지도학습 기반 기계학습 방법인 베이지안 분류기, 인공 신경망 및 서포트 벡터 머신을 이용해 기존에 제시된 퓨리에 기술자 및 웨이블릿 기술자와 비교하였다.

This study is to find out why drivers used to put pseudo-petroleum in their cars and to fundamentally remove any accidents from the misuse. Questionnaire survey has been made in Gimpo area where many drivers can use it comparatively easily outside of Seoul. And they are analyzed statistically using SPSS 12.0 package program. Correlation factor is shown with 0.683, very high relationship between using frequency and use period of cars. It is shown that important factor to give impact to consumer attitude has been produced as car-using period, education level. The longer the cars have been used, the more pseudo petroleum has been used, it is found.

The purpose of this study was to determine whether foodservice brand language localization affects consumer attitudes in terms of similar brand image recognition with an original brand. Many global foodservice companies have tried to modify their own brand identity according to local situations in order to attract more consumers. According to this study's results, consumers who similarly recognized both the original brand image and localization brand image tended to have greater purchase intention than those who did not recognize them similarly. In addition, when the original brand identity was changed to the local language, consumers more similarly conceived the original brand image and localization. And for local store marketing, foodservice companies should have a thorough marketing research plan since there can be difference results according to brand name recognition gaps or demographic characteristics. Original brand image similarity recognition by consumers affected their attitudes. In other words, the group that similarly recognized both the original brand company image and the localization brand company image tended to have greater purchase intention. Because brand language plays an important role in consumer attitudes with respect to recognizing a brand and distinguishing another brand, this study suggests that franchise foodservice companies have a local store marketing plan.
