The goal of this research is to develop the method of facility management which is used to manage the facility efficiently by using existing analyses of a system and a operation, and establish the method of a facility administration by applying AHP(Analytic Hierarchy Process) model. Because the standard of a accuracy in spacial analysis and calculation is a unclear, the exact analysis of a geographic data for a decision-making needs statistical analysis and administrator-centered type of system didn't satisfy the desire of users. There must be the existing general statistics module, integrated internet GIS and the composition of interface in order to structure a spacial statistics analysis methods that satisfy the matters desired in internet GIS into the spacial analysis function. This paper presents the need of internet GIS and AHP Model in supporting and managing function of all facilities in campus and introduce the possibility of applying.

In a ubiquitous computing environment, people more and more become to use multiple displays. When using such ubiquitous displays, it is needed for users to seamlessly interact with the displays for a certain content. In this paper, we propose a seamless interface that allows users to see photos across multiple displays. Many photos can be displayed on a screen at the same time because they are shown in 3D space. And a group of photos is represented using a cube metaphor. A user can manipulate photos directly using a touch screen and also see the photos continuously using PDAs when the user moves to other places. In addition, the user can interact with the photos seamlessly using another display. The developed system was designed to interact according to user's movements and not to draw user's attention too much as a kind of ambient display. Using RFID and ultrasonic sensors it recognizes a user and the user's proximity to the display, and then automatically determines the screen image and the user interface accordingly.

The purpose of this study is to investigate the effect of Jeju dialect of service worker on tourist image, tourist satisfaction and revisit intention. The Regional dialect can be viewed as a cultural element that characterizes the region, It also serves as a medium to inform tourists of the feelings they experience while they are out of their area and visiting other areas. As a result of the study, it was found that the communication factors in the language communication of dialects had a positive(+) effect on the cognitive and emotional images of tourist sites. Interesting factors showed positive(+) effect on cognitive image of sightseeing spot, but did not affect emotional image. As a result of the study, it should be noted that excessive use of regional dialects may not necessarily have a positive effect on the emotions of tourists. If you want to develop tourist products using dialects, you need to pay attention to the use of words and expressions so that there is no misunderstanding.

As the field of robots is evolving to intelligent robots that can replace even humans' mental or emotional labor, 'robot ethics' needed in relationship between humans and robots is becoming a crucial issue these days. The purpose of this study is to consider the ethics of robots and humans that is essential in this post-human age. It will deal with the followings as the main contents. First, with the cases of developing ethics software intended to make robots practice ethics, the authors begin this research being conscious about the matter of whether robots can really judge what is right or wrong only with the ethics codes entered forcibly. Second, regarding robot ethics, we should consider unethicality that might arise from learning data internalizing human biasness and also reflect ethical differences between countries or between cultures, that is, ethical relativism. Third, robot ethics should not be just about ethics codes intended for robots but reflect the new concept of 'human ethics' that allows humans and robots to coevolve.

종이가 인류의 생활에 미치는 비중은 정보의 전달을 제 l의 목적으로 사용되고 있는 인쇄용 지와 필기용지가 차지하는 것이 가장 크다. 정보전달의 매개로 사용되는 종이의 용도 이외 의 것을 살펴보면 전사지, 감압.감열지, 절연지,OMR지, 항공권지, 벽지 등과 같은 특수지와 기능지가 있다. 특히 벽지는 다양한 문양과 색감으로 인간의 미적 감각과 정신적 안정감에 미치는 영향이 크다. 벽지의 기능은 여러 가지의 목적으로 우리들의 실생활에 있어서 없어서는 안될 중요한 건축 재료로서 사용되고 있다. 가장 중요한 벽지의 목적은 앞서 언급한 바와 같이 미려한 색상과 다양한 디자인으로 도안.인쇄 및 발포 처리된 벽지를 사용하여 단순한 벽면을 개인의 취향 에 맞게 함으로써 심리적 안정감을 가져옴과 동시에 미적 가치를 증가 시켜 문화 수준의 향 상에도 영향을 미치는 것으로 알려져 있다. 그러나 종이 벽지와 종이 벽지 원지를 기저로 하여 제조된 발포 벽지는 인화성이 강하기 때 문에 이들에 대한 적절한 난연 처리가 요구 되고 있다. 매년 발생되는 다양한 형태의 화재 는 돌이킬 수 없는 인명과 재산의 손실로 귀결되어 각별한 주의가 요구되기 때문에 주거공 간과 대중의 군집이 많이 이루어지는 공공장소에서의 난연 처리된 벽지 사용에 대한 중요성 이 나날이 그 강도를 더 해가고 있는 실정이다. 난연 처리된 벽지는 통상적인 벽지에 비하 여 제조 원가의 상승에 따라 가격이 비싸기 때문에 일반인들에게 있어서 그 사용은 주목할 정도로 증가되지 못하고 있으나, 생활 수준이 향상 될수록 안전에 대한 의식 강화와 정부의 노력으로 인하여 그 사용량은 크게 늘어날 것으로 기대된다. 따라서 본 연구에서는 종이의 제조에 사용되는 원지의 충전제 종류와 양 그리고 난연 처리 된 폴리에스테르 섬유의 혼합을 달리하여 제조된 원지를 사용하여 난연 처려한 후 이들의 인화 특성에 대해 고찰 함으로써 보다 향상된 성능을 발휘 할 수 있는 난연 벽지의 제조와 개발에 보탬이 되고자 하였다.

In this paper, a moving storm in the real watershed was simulated using a distributed model. Macks Creek Experimental Watershed in Idaho, USA was selected as a target watershed and the moving storm of August 23, 1965, which continued from 3:30 P.M. to 5:30 P.M., was utilized. The rainfall intensity of the moving storm in the watershed was temporally varied and the storm was continuously moved from one place to the other place in a watershed. Furthermore, runoff parameters, which are soil types, vegetative cover percentages, overland plane slopes, channel bed slopes and so on, are spatially varied. The model developed in the previous paper was utilized as a distributed model for simulating the moving storm. In the model, runoff in a watershed was simulated as two parts which are overland flow and channel flow parts. The good agreement was obtained between a simulated hydrograph using a distributed model and an observed hydrograph. Also, the conservations of mass are well indicated between upstream and downstream at channel junctions.

최근 호두 기내 소비량은 급증하나 대부분 실생묘로 조림되어 결실까지 장기간 소요되며, 무성 번식률이 낮아 보급확대가 어렵다. 본 연구는 호두나무 관행 묘목 번식법 개선이 가능한 우량 국산묘 대량증식 기술 개발로 최적 배양조건을 구명하고자 수행하였디. 호두나무 등 목본류는 식물 조직배양 기본배지에서 산화방지제를 첨가하여 사용하는 경우, 배양체에서 생기는 페놀 화합물(Phenolic compound)의 작용을 억제하여 배양 식물체의 갈변(Browning) 또는 흑변(Blackening) 현상을 감소시키는 효과가 있다. 페놀 추출물은 배지로 빠져나와 갈변시키며 생존율을 저하시키는 원인이 되고 이를 제거하는 산화방지제는 배양 식물체의 생산효율을 높이는 효과를 나타내는 강력한 항산화제(Antioxidant) 역할을 한다. 호두나무의 액아를 배양하게 되면 조직 및 배지의 갈변화가 심하게 일어나는데, 휴면 정도가 깊을 수록 정단에서 추출되는 페놀성 물질의 함량이 증가하며, 식물 조직 내 페놀성 물질의 함량 정도와 배양의 고사율과는 상관관계가 있다. 이러한 식물 배양체에서 생기는 페놀 화합물에 의해 발생되는 배양상의 문제점을 해결하기 위하여 계대배양을 자주해 주거나 활성탄(Activated charcoal), Ascorbic Acid 등의 첨가물을 배지에 추가하는 방법이 있다. 이에 따라 호두 '신령' 품종의 액아배양의 페놀집적을 제거하기 위해 배지 내에 산화방지제 첨가물질 등을 농도별로 처리하였다. 호두나무 액아 배양 후 8주차 산화화방지제 첨가물질의 농도별 처리 효과는 생존율은 85.3%를 보였으며, 신초 형성율 76.4%, 신초수 1.9개/주, 신초장 27mm/주의 양호한 결과를 나타냈으며, 페놀 제거 및 유식물체 고사 억제 효과를 보였다.
