In this paper, we propose a Smart Adapted Service which can manage a schedule automatically. Smart Adapted Service gives a notice beforehand regarding information associated with the schedule, by searching the Internet. If the user has written down the name of goods or food which he wants to buy, Smart Adapted Service finds the most suitable store nearby him using the user's favorite list. The user's favorite list is created by Outlook Web Access System by analysing the schedule and habits of the user. User can access Smart Document System remotely through the Internet using Outlook Web Access System. We developed an Auto AP Roaming System for seamless communication and Smart Document System for arranging the information.

The image segmentation is the most important operation in an image processing system. It is located at the joint between the processing and analysis of the images. Unsupervised segmentation aims to automatically separate the image into natural clusters. However, because of its complexity several methods have been proposed, specifically methods of optimization. In our work we are interested to the technique SFLA (Shuffled Frog-Leaping Algorithm). It's a memetic meta-heuristic algorithm that is based on frog populations in nature searching for food. This paper proposes a new approach of unsupervised image segmentation based on SFLA method. It is implemented and applied to different types of images. To validate the performances of our approach, we performed experiments which were compared to the method of K-means.

NAD(P)H:quinone reductase (QR), known as DT-diaphorase, is a kind of detoxifying phase II metabolic enzyme catalyzing hydroquinone formation by two electron reduction pathway from quinone type compounds, and thus facilitating excretion of quinoids from human body. With the usefulness of QR induction activity assay system for the modulation of toxicants, in the course of searching for cancer chemopreventive agents from natural products, the methanolic extracts of approximately two hundreds of oriental medicines were primarily evaluated using the induction potential of quinone reductase (QR) activity in cultured murine Hepa1c1c7 cells. As a result, several extracts including Hordeum vulgare, Momordica cochinchinensis, Strychnos ignatii, Houttuynia cordata, and Polygala japonica were found to significantly induce QR activity. In addition, the methylene chloride fraction of H. vulgare, one major dietary food source, showed potent induction of QR activity $(CD=6.4{\mu}g/ml)$. Further study for isolation of active principles from these lead extracts is warranted for the discovery of novel cancer chemopreventive agents.

The fiddler crab, Uca lactea, which lives on intertidal mudflats in Korea, exhibits both burrow mating and surface mating. We observed 17 cases of surface mating that occurred on Ganghwa Island, South Korea. Most surface-mating males did not build semidomes, structures that attract searching females for burrow mating. Based on the conclusion of a previous study that semidome building is condition-dependent, we suggest that food availability may influence the mating tactic of this species. In addition, there was a strong correlation between the carapace size of both sexes that surface-mated, which suggests that males use body size of females as a mating cue.

오늘날은 유용한 정보의 확보 및 이용이 경쟁의 중요한 원천이었던 과거 정보화시대와는 달리 정보를 토대로 새로운 지식을 창출하여 현장에 적용하는 지식정보화(지식경영) 시대이다. 이 같은 지식정보화 시대에는 누구나 인터넷을 기반으로 하는 검색서비스를 이용하여 필요한 자료 및 정보를 손쉽게 얻을 수 있기 때문에 더 이상 단순한 정보의 획득이 개인, 기업, 국가의 경쟁력이 될 수 없게 되었다. 이러한 지식정보화라는 시대적 요구는 사회 각 분야에서 지식경영 시스템(Knowledge Management System) 등을 통해 급속도로 변화되고 있으며 여러 학문분야에서도 활발한 연구가 진행되고 있으나 디자인분야는 아직까지 일반적인 디자인 자료에 대한 단편(일차원)적인 검색서비스 수준에 머물러 있는 실정이다. 이에 본 연구에서는 가전제품, 생활용품, 의류제품, 식료품관련 회사들의 각 제품에 대한 CI/BI에 대해서 형태, 색상, 심미적 요소, 선호 이미지 언어, 만족도 등을 조사한 자료를 데이터베이스를 구축하고 이를 바탕으로 디자이너가 새로운 제품에 대한 CI/BI 작업을 수행하는데 있어 유용한 자료 및 정보를 얻을 수 있는 검색 시스템을 제안하였다. 특히, 제안된 시스템은 디자이너가 특정 BI/CI를 개발해야 하는 경우 기존 BI/CI에 대한 다양한 검색결과는 유용한 디자인 컨셉을 제공할 것이다. 또한 기존 디자인에 대한 디자인요소(형태, 색상, 심미적 요소, 선호 이미지 언어)들의 이차원 범주형자료 분석결과인 분할표(Cross Table)는 디자이너가 새로운 디자인지식을 창출하는데 기여할 것이다.
