  • In this study, we will develop the sea surface interpretation system that can aware the target in the bottom of the sea. we will setup the database whose records would be the signal patterns of formation about mud, sand, rock and sea shell achieved by using supersonic. then we will convert analog signal received in fish detector to digital one using A/D converter So we can process and analyze this signal pattern then compare it to the one in our Database at the real time to identify the target in the bottom of the sea. After enough times of experiments from the background of the results that have been achieved from many studies(including a water tank experiment and a field investigation), we can aware the exact information of the sediment and the sand in the sea. By analyzing the first, second and third signal of the supersonic characters reflected from the body of a fish categorized by its family and from the body of shellfish, muddy sand, sand and rocks, We will develop the sea surface decipherment system which abstracts the first signal that shows the target in the bottom of the sea and makes the second and third signals filtering.

  • In Biology, Studies Using Electron Microscopy for making Cell Structure to 3D reconstruction very fast development. Recently, by using Cryo fixation, we can see cell 3D structure without structural change, instead of using chemical fixation which can change cell structure. Before using this technology, we could understand cell structures only in 2D images. But now, through cryo-ET, 3D reconstruction of cell structure without artificial structure changes can be possible and this technology will give us many advantages in Drug delivery and Nanothechnology.

  • Collaborative spectrum sensing has been found to be an effective means for detecting the activity of primary users in a fading environment. Most previous works on collaborative spectrum sensing are based on the assumption that the local spectrum sensing decisions of secondary users are statistically independent. However, it may not hold in some practical situations. In this paper, we consider a cognitive radio network where the local spectrum sensing decisions of secondary users are statistically correlated with the same level of correlation if they are next to each other in location and statistically independent, otherwise. Then, for the system, we analyzed the performance of the collaborative spectrum sensing with the AND and the OR fusion rules and found that the scheme with the AND fusion rule performs better than the one with OR fusion rule when the degree of correlation is significant.

  • 차세대 지뢰탐지 기술로는 NQR(Nuclear Quadrupole Resonance, 핵4중극자공명), GPR(Ground Penetrating Radar, 지상 침투 레이더)등 이 연구 및 개발 중 이다. 현재 우리나라에서도 이중 GPR을 차세대 지뢰탐지 기술로 연구중에 있다. 그렇지만 지금까지 개발된 GPR 기술을 적용한 지뢰탐지기는 얻어진 2차원 영상에 대해서 육안에 의한 식별만이 가능하여 지뢰 식별이 장시간 소요된다는 단점을 가지고 있다. 이에 본 논문에서는 그러한 문제를 해결하기 위해 주성분 분석법을 적용하여 해결하고, 제안된 시스템이 가능한지 확인하기 위해 유사한 실험 환경을 구성하고, 얻어진 영상을 학습시켜 실제로 얻어진 영상에 대한 분류가 가능한지를 확인하였다.

  • 화주의 선박 선정과정은 선박과 화물의 일정에 따른 1차 선정과 화물을 재선적하여 하나의 단위로 선복을 집중시키는 2차 선정으로 구분된다. 지금까지 3자물류업체는 이러한 선적업무가 수작업으로 진행됨으로써 비효율성을 초래하였다. 그러므로 본 연구에서는 에이전트 협상을 통해 전체 물류비를 감소시킬 수 있는 방안을 제안하고자 한다. 화물의 집중과 배분을 통해 얻을 수 있는 물류비 절감을 최대화 시키기 위해 재고비와 운임비간의 상관관계에서 최적점을 찾아야 하며 이를 화주간 협상으로 해결할 수 있다. 실험에서는 현업에서 이루어지는 화물 선적방법인 EPDS(Earliest Possible Departure-Date Scheduling)와 LPDS(Latest Possible Departure-Date Scheduling)에 본 협상방법론을 접목하여 SBF(Scheduling Bundle Factor, 선적동시처리량)에 따른 재고비, 운임비 그리고 물류비 등을 도출하고 실험결과를 분석 하였다, 분석결과, 협상방법론이 EPDS와 사용될 경우 전체 물류비를 최소화 시킬 수 있었다.

  • This study which is based on the Master's and Doctor's theses printed from the Korean liberation day to 2003. It has been carried out to research the trends of tea culture in Korea, by analyzing the current printing situations on the kinds of degrees, the chronicles of theses and tea culture. It has found out that the total number of the theses was 276, which of them were for a master's degree, up to $232(84\%)$. As for the printing time, it increased in the mids of 1990s and soared up sharply in 2003. For the fields, the theses on the efficacy of tea printed 178, which reached $64.4\%$, 148 of them were on the medical and pharmacological view and reached $83\%$. For the cultural view, the theses on reached only $6.9\%$. Recently, the theses on the marketing or the education of Da-do haven been increasing sharply.

  • As Korean cuisine is one of our cultural assets and has global potential, it needs to be better marketed and known to the world. However, there is a lack of research examining what to and how to globalize Korean cuisine practically. Therefore, the purpose of this study is to suggest fundamental reasons and ways to globalize Korean cuisine from a multicultural point of view. A Delphi method was selected because the study is suitable for a structured group of experts instead of unstructured groups or individuals. A panel of experts were selected from two groups, Korean experts and international experts. This research established the characteristics of Korean foods, the difficulties of Korean cooking methods and the incorporation or substitution of Western ingredients in two rounds. A panel of experts suggested strategies for globalizing Korean cuisine in the third round. As a result, meaningful solutions were suggested such as increasing the global profile and knowledge of Korean cuisine from 18 experts out of 23, developing various cooking methods for Korean-cuisine having distinctively Korean characteristics from 17 experts out of 23, developing recipes that are compatible with equipment and appliances in a western kitchen, and considering the differences in taste and texture(mouth-feeling) between Korean and the Western people.

  • In the history of the design movement since 18708 in Japan, four eras can be seen; the first era started with the opening of Meiji era and oontinued to the World War I, the second era to the World War II, the third era from right after the second world war to 1960, and the fourth era after 1960. Before the second world war, the design education of Japan had been influenced by plenty of modem design movements which brought about in Europe such as Art and Craft Movement of William Morris, Deutscher Werkbund, and Bauhaus and by American industrial design after the World War II. Japan which early introduced western civilization established design department in universities in 1940 professing itself to be a original design education. And Japan has kept making progresses with the help of design policies of the government until now, and has seen the tornadoes of education revolution in every university after the oollapse of bubble eoonomy.

  • We analyzed the introduction factor of ASP-based information system on the order of importance using AHP techniques. We classified the introduction factors from previous studies into three categories : Organizational factors revealed organizational factors to be of highest importance, followed by environmental and Quality factors. The analysis on both primary and secondary hierarchical factors revealed CEO support as the most important, followed by IT capability, provider reliability, and cost-cutting expectation.
