본 논문에서는 3차원 모델을 검색하기 위한 형태 기반 기술자를 추출하는 알고리즘을 제안한다. 제안하는 알고리즘은 모델의 기하학적인 특성을 고려하여 레이 캐스팅 샘플링과 구면조화함수를 이용하는 방법이다. 레이 캐스팅 기법은 모델의 외형을 고려한 적응적인 방법으로 샘플링 하여 기술자에 포함되는 형태 정보를 증가시켜 기술자의 식별성을 높인다. 또한 구면조화함수 계수 추출에서는 기하학적인 주파수 특성을 고려하여 적응적인 계수를 추출한다. 이 방법은 검색 성능에 영향을 미치지 않고 기술자를 조밀하고 간결하게 만든다. 최종적으로 두 방법을 결합함으로써 검색 엔진에서 이용 가능한 기술자를 생성한다. 실험 결과에서는 제안된 알고리즘의 성능이 기존 방법에 비해 약 12.5% 향상 된 것을 확인 할 수 있다.

디저트 소비자가 늘어나면서 전통한과에 대한 관심이 증가하고 있다. 특히 한과는 건강한 디저트 음식을 선호하려는 소비자와 문화적 가치를 함께 즐기고자 하는 소비자들에게 적당한 음식이 될 수 있다. 본 연구는 한과 소비자 인식에 관한 주관성 연구로서 한과에 대한 다양한 주관적 견해와 유형을 살펴보고자 하는 것이다. 그 결과 총 4개의 유형이 발견되었으며 각각의 유형에서 독특한 특성을 확인하였다. 제1유형은`박물관에 박제된 전통문화`로 현대인들의 입맛에 맞지 않는 음식으로 인식하고 있었으며, 제2유형은 `한국적 팔방미인의 진수`로 시대에 상관없이 모두가 즐겨 먹을 수 있는 음식으로 이해하고 있었다. 제 3유형은 `감성적 추억의 향수`로 음식으로서의 매력보다 마음을 채워주는 음식으로 받아들이고 있었다. 마지막으로 제4유형은 `외형뿐인 폐쇄된 전통음식` 으로 현대인들과 소통이 단절된 전통문화이며 그에 대한 아쉬움을 표출하고 있었다. 각 유형들은 한과에 대한 개인들의 주관적 인식에 따라 차이가 있었다. 그리고 각 유형별 특성을 분석한 후 상품개발에 필요한 컨셉을 제시하였다. As dessert consumers increase, interest in Hangwa, a traditional Korean confectionery, is also on the rise. Hangwa can be a good dessert food particularly for consumers who want to enjoy healthy dessert food as well as cultural values. This study is aiming to investigate consumers` various subjective opinions about Hangwa in order to identify factors of consumers` perception of Hangwa. The findings revealed that there were four different factors of consumers` perception about Hangwa and each factor had its unique characteristics. The first factor of perception is viewing Hangwa as `a stuffed traditional culture`, in which Hangwa was perceived as a food that was not to the taste of modern people. The second factor is the consumers` perception that Hangwa is `the essence of an all time favorite Korean food` that everyone can enjoy. In the third factor of perception, consumer perceived it as a food that filled their mind rather than as a tasty food, which is dubbed as perception of `the fragrance of emotional memories.` Finally, the fourth factor is labelled as the perception of ` a vestige remains of traditional food`, in which consumers viewed it as a traditional culture that is being cut off from modern culture and they expressed regret about it. Since each factor of perception was different depending upon individual perceptions of Hangwa, the current study proposed the communication message relevant to each factor of perception along with the product positioning strategy for product development based on the findings of the characteristics of each factor.

국내 식품 소비 트렌드가 웰빙과 전통으로 전환되면서 슬로우 푸드나 로컬 푸드에 대한 소비자들의 관심이 높아지고 있다. 떡은 이를 대표하는 음식으로 인정을 받고 있으며 최근에는 새로운 디저트 상품으로서도 각광을 받고 있다. 이와 함께 제품의 디자인적 측면에 대한 소비자들의 요구 또한 갈수록 증가하고 있다. 따라서 본 연구는 떡에 대한 소비자들의 태도나 이용하려는 이유 또는 선호 등 다양하게 나타날 수 있는 주관적 특성에 대해 연구하였다. 떡 이용자들의 유형을 구분하고, 구분된 유형의 특성을 파악한 후 향후 상품개발에 필요한 전략적 컨셉을 제시하기 위해서이다. Q 방법론과 QUANL 분석프로그램을 활용하여 38개의 Q 표본과 32명의 P 표본을 연구에 사용하였으며, 그 결과 다섯 개의 유형이 발견되었다. 제1유형에서의 떡은 유용성을 갖춘 음식으로 실용성이 많고 이용이 편리해서 유용한 요소로 인식된다. 제2유형에서는 떡이 필수음식이 되는데 특별한 용도뿐만 아니라 일상적인 용도로서 다양하게 섭취할 수 있는 것이다. 제3유형에서의 떡 섭취는 관습에 불과하다. 의례적인 행사나 답례음식으로서 보편적으로 사용하는 것으로 인식하고 있다. 제4유형에서는 떡 섭취가 주는 효용성 때문에 이용하려는 것이다. 떡은 건강에 도움이 되는 음식이자 농산물 소비에 기여하는 이로운 음식이기 때문이다. 제5유형에서의 떡은 오래전부터 먹어온 음식이자 추억의 향수를 느끼게 해주는 친근한 음식이다. 한편, 각각의 유형들은 독특한 특성을 지니고 있었으며, 이를 근거로 하는 상품개발 및 디자인 컨셉을 제시하였다. The consumers have shown their high interests in slow food and local food, while the domestic trend in Korea in terms of food consumption is moving towards well-being and tradition. The ‘Tteok’, traditional Korean rice cake, is recognized as a representative food following that trend and also recently as a new dessert. In addition, consumers are increasingly demanding design aspects. This study investigated such subjective characteristics as attitudes, reasons to use, and preferences of consumers in regard to the Tteok. The purpose of this study is to present the strategic concept necessary for new product development of the Tteok, based upon the usage types derived and their individual characteristics. Five types were derived after Q samples of 38 and P samples of 32 were applied by Q-methodological and QUANL analysis program. The first type about the Tteok is useful food. It is recognized as an useful element because of the practicality and convenience. The second type is life intimate food, which is interpreted to be realistic as well as symbolic. This second type can be considered as an essential food for the individual's life. The third type is custom food, by which means that it is used as a ritual event or delivered as return courtesy. The fourth type is effective food in the sense that it is a healthy food and beneficial food contributing to the consumption of agricultural products. The fifth type is familiar food, a food that we have eaten since childhood and reminds us of that time. Since each type has its own characteristics, based on this, product development and design concept are presented together.

With urbanization and other development-related activities, construction of impervious surface continues to increase. Water-related environmental issues of watershed have also been raised with regard to water quality deterioration, flood crisis and drying of the river. The increase in frequency of localized heavy rainfall due to climate change has likewise led to considerable human and material damages. In a related move, the mandatory installation of Rainwater Harvesting Facility has been pushed to minimize environmental loads and construct sustainable eco-cities in terms of urban planning. As such, this study was designed to present installation standards based on the calculations of private and social benefits to recover the initial investment of facilities using rainwater through cost-benefit ratio analysis of Rainwater Harvesting Facility. It is the result of analysis that more than 50 households are desirable. We also found that investment cost recovery period has been curtailed if households are increased. consequentially, On this study, we suggest that 50 households be the Criteria of the Multi-Family Housing Rainwater Harvesting Facility which has economical validity.

In early childhood media education, parents and teachers media literacy transfers to direct interactions with toddler and interactions between parents and teachers. However, little attention has been paid to the differences in parent and teacher groups regarding their perceptions of media literacy. This study investigated the differences and relationships among parents and teachers in terms of their perceptions of media literacy. The focus was directed at building co-orientation models regarding the sub-components of media literacy and media literacy experts participation in early childhood media education. Further, we analyzed the types of each co-orientation model, and we discussed the need for communication between parents and teachers in early childhood media education. In order to analyze the main research questions, a self-report online survey was conducted with a total of 203 parents of toddlers residing in the metropolitan area and teachers employed at early childhood education institutions in the metropolitan area. As a result of the analysis, the co-orientation model for critical understanding and citizenship, a sub-component of media literacy, corresponded to ignorance. The agreement between parents and teachers on critical understanding and citizenship was consistent. However, the congruency between the two groups did not agree. They responded that the others would not perceive their critical understanding positively as they did. On the other hand, regarding citizenship, they answered that the other person would perceive them more positively than themselves. In other words, it was confirmed that there is a possibility of a perceptual bias in which the other party misunderstands that the parents and teachers have similar perceptions about critical understanding and citizenship but are different from their own. Concerning self-expression, both parents and teachers answered that teachers of early childhood education institutions would perceive them more positively, and both groups recognized this difference in perception relatively accurately. The analysis of the co-orientation model regarding the participation of media literacy experts in early childhood media education was partially inconsistent. In other words, teachers perceived more positively than parents about participation in media education for children in media literacy-related institutions, including media education instructors and universities. Teachers recognized these differences relatively accurately, but parents tended to respond that teachers perceptions about the participation of media literacy experts would be similar to themselves. The paper concludes by mentioning some of the implications raised by this approach to the necessity of a media education program in which teachers and parents participate together or the need for education in connection with media literacy experts.

후박추출물은 중국 원산인 당후박에서 제조되며, 항산화 및 항염증 효과로 알려져 있다. 후박의 성분으로는 폴레페놀인 honokiol 및 magnolol 등이 알려져 있다. 이 연구에서, 우리는 후박추출물이 triglyceride (TG)의 축척을 감소시킴으로써 지방세포 분화를 억제한다는 표면적인 결과를 얻었다. 또한, 후박 추출물이 hormone sensitive lipase (HSL) 단백질 수준을 증가시키고 adipocyte에 specific한 transcription factors로 peroxisome proliferator activated receptor (PPAR)-γ의 단백질과 mRNA 수준을 억제하였다. 결과적으로, 후박추출물이 항비만제로서 adipogenic transcription factor와 그들의 특이적인 유전자의 발현을 억제함으로써 지방세포 분화를 억제한다고 사료된다. Magnolia extract, prepared from the Chinese herb Magnolia officinalis, is known for its potent anti-oxidative and anti-inflammatory effects. In this report, we showed that Magnolia extract inhibits adipocyte differentiation, as evidenced by reduced triglyceride (TG) accumulation. Also, Magnolia extract increased hormone sensitive lipase (HSL) protein level, and decreased the adipogenic transcription factor peroxisome proliferator activated receptor (PPAR)-γ protein and their corresponding mRNA. Our results suggest a potential apllication of Magnolia extract as anti-obesity agents inhibits adipocyte differentiation through the down-regulation of adipogenic transcription factors and other adipocyte-specific genes.
