In this paper, we propose a NPC decision making model based on Prospect Theory which tries to model real-life choice, rather than optimal decision. For this purpose, we analyse the problems of reference point setting, diminishing sensitivity and loss aversion which are known as limitations of the utility theory and then apply these characteristics into the decision making in game. Dynamic Terrain Analysis is utilized to evaluate the proposed model and experimental result shows the method have effects on inducing diverse personality and emergent behavior on NPC.

국내 인터넷 활용인구의 증가와 함께 연령층의 확대로 초등학생 인터넷 이용률은 날로 높아지고 있다. 어린이들에게 인터넷은 이미 친숙한 매체이며, 효과적인 학습도구로 활용되고 있다. 아이콘은 사용자가 클릭을 통해 다른 곳으로 이동할 수 있도록 방향성을 제시하는 navigator 역할로 사용자들의 행동을 유도하는 기능을 가지고 있다. 어린이를 주 이용 대상으로 하고 있는 어린이 포털 사이트의 경우 아이콘의 기능은 무엇보다 중요하다. 그러므로 아이콘을 지각하는 어린이의 감성을 파악하는 것은 필수적인 과정이다. 따라서 이러한 어린이 포털 사이트의 아이콘을 제작함에 있어, 사이트 방문자인 어린이의 감성을 조사하여 효과적인 아이콘 설계 방안을 제시하고자 한다. 이를 위하여, 이용자 접속률이 높은 세 개의 국내 어린이 포털 사이트의 아이콘 샘플을 추출하고 이를 서울지역 초등학생을 대상으로 선호 이미지 형용사를 조사하였다. 이는 향후 어린이를 대상으로 한 다양한 서비스에 기초 자료로 활용될 수 있을 것이다.

급속도로 변화하는 환경에 적응하기 위해서 환경의 변화에 대한 요구와 신속한 응답능력을 향상시키고, 에이전트간 의사결정의 지속시간을 줄이기 위하여 에이전트간 효율적인 조정에 관련된 의사결정을 하기위한 대안(alternative)결정과 사용자의 선호도를 어떻게 유도할 수 있는가라는 문제가 요구된다. 본 논문에서는 사회적(Pareto) 최적성이라는 관점에서 의사결정의 행동을 효과적으로 시뮬레이트하기 우해 퍼지 의사결정에 기반한 멀티에이전트의 효율적인 조정방안을 제안한다. 또한 제안하는 방법에서는 가중치를 사용하여 각 속성이 멀티에이전트와 관련하여 최적의 대안을 생성하고, 퍼지 의사결정에 기반한 멀티에이전트의 의사결정방법에 기존의 방법보다 가중치를 사용한 방법이 높은 신뢰도를 가지면서 더 빠른 의사결정을 한다는 것을 확인하였다.

The present study was undertaken to examine the effects of ginseng saponins [ginseng total saponin (GTS), protopanaxadiol saponin (PD) and protopanaxatriol saponin (PT)] on the hyperactivity, reverse tolerance and dopamine receptor super-sensitivity induced by cocaine. A single treatment with cocaine produced hyperactivity. Repeated administration of cocaine developed reverse tolerance and dopamine receptor super-sensitivity was also developed in reverse tolerant mice which had received the same cocaine. The hyperactivity and the developments of reverse tolerance and dopamine receptor super-sensitivity by cocaine were inhibited by ginseng saponins. From these results, it is proposed that ginseng saponins may be useful for the prevention and therapy of the adverse actions of cocaine. In addition, the rank order of inhibitory potential was observed as PT>GTS>PD. Key words Cocaine, hyperactivity, reverse tolerance, dopamine receptor super-sensitivity, ginseng saponins.

최근 규칙적인 수면을 이루지 못해 수면장애를 호소하는 사람들이 좌시하기 어려울 정도로 늘어나고 있는 추세이다. 수면장애 치료를 위한 보편적인 방법은 수면제 투여이나, 약물의 지속적인 투여로 인해 약물의 내성 및 의존성 등의 부작용이 일어날 수 있다. 따라서 근래에는 비약물적인 인지행동치료(Cognitive Behavior Therapy)를 통해 환자가 스스로 자신의 상태를 이완시킬 수 있는 훈련을 제공하고 있다. 하지만 치료를 위해서는 병원과 환자 모두 많은 시간과 비용이 든다는 문제점이 있다. 따라서 본 논문에서는 환자 혼자서도 바이오피드백 훈련이 가능하도록 하는 시스템을 제안한다. 이 시스템을 통해 좀 더 효율적인 수면장애 치료를 기대할 수 있다.

The purpose of this study was to obtain database for development of education and programs of dental examination in industries. survey and dental examination was conducted by dental hygienist and dentist, and the data from 1016 respondents were analyzed. The result obtained was as follows: 1. Dental disease was 58.2% among 1,016, there was most a lot of peridontal disease, and overlapping disease, dental caries, missing tooth, fracture and abrasion, in order. 2. Utilization of dental care was 40% for last six months, it was significant high that age and working periods, married in marriage state, and unhealthy in subjective dental health state. 3. It was significant high that woman, fourty ages, middle economic state and working periods in above three times of tooth brushing a day. 4. Utilization of dental hygiene auxiliary devices was 41.8%, it was significant high that age, marriage state, economic state and working periods. 5. As for relationship between dental disease status and dental health behaviors, a person without periodontal disease was significant high in above three times a day, and a person without extraction, a person with fracture and abrasion, a person without overlapping disease was significant high in utilization of dental hygiene auxiliary devices.

This research was designed to seek and plan the foreign tourists visiting the National Hangeul Museum revitalization method; foreign tourists in this research refer to Japanese, Chinese and Americans tourists since they make up the big proportion of foreign tourists visiting the National Hangeul Museum. This research was aimed to seek the visiting revitalization method through correlation analysis among: foreign tourists' visiting purpose, requested improvement on exhibition facility and service, satisfaction level on exhibited contents and service quality, overall satisfaction level on viewing exhibition and behavior intention. As the result of research, tourists visiting purpose from three countries showed a difference; American and Japanese tourists picked 'guidance system in foreign language' while Chinese tourists picked 'experiment programs' as the most requested improvement on exhibition facility and service. Also, Tourist' satisfaction level on exhibited contents and service quality showed a difference among tourists from three countries; American tourists' satisfaction level was shown higher than that of Japanese and Chinese tourists. In addition, American tourists' overall satisfaction level on exhibition and behavior intention after viewing the exhibition in National Hangeul Museum tends to be higher than that of Japanese and Chinese tourists. Based on this research, visiting revitalization method to attract more foreign tourists to the National Hangeul Museum, such as contents development is suggested in the research.

With the increasing needs on various leisure activities, the users of passenger ships and cruisers have been increased year by year. Although over 15 accidents per year betide on domestic passenger ships for last decade, the researches on the safety of crews and guests on boards are difficult to find. This study performed the comparative analysis by experiments on the evacuation characteristics between experience levels on board a training ship. The followings are the results. From the seniors' experiments, it is found that more various evacuation scenarios have to develope and drill as a part of education contents. And from the freshmen's trials, the importances of the evacuation education and the roles of existing crews on evacuation guides are pointed out as to increase the safety of new crews and/or guests who are not accustomed to onboard a ship. On the other, it is explained that the communications between evacuees are worthy and useful, and also save more evacuation times. And on the viewpoint of evacuation methodology, it is clear that captain and evacuation-related crews have to control all the evacuation passages and evacuees of each passages to save more lives.

Consumption of high doses of ethanol can lead to amnesia, which often manifests as a blackout. This incoordination of blackout may be a major cause in various social problems in alcohol consumption. However, there is still no treatment for preventing these alcohol-induced problems. Hydrangeae dulcis folium is a drug or a tea which is made from the fermented and dried leaves of Hydrangea serrata Seringe. The present study, we tested the ethanol extract of the Hydrangeae dulcis folium (EHDF) on ethanol-induced psychological deficits. To test behavioral deficits, an object recognition test was conducted using a mouse model. To evaluate synaptic deficits, N-methyl-D-aspartate (NMDA) receptor-mediated excitatory postsynaptic potential EPSP and long-term potentiation (LTP) in the mouse hippocampal slices were tested, as they are known to be vulnerable to ethanol and are associated with ethanol-induced amnesia. In the tests, ethanol (1 g/kg, i.p.) impaired object recognition memory, but EHDF (10 or 30 mg/kg) prevented this impairment in object recognition test. Interestingly, EHDF ($30{\mu}g/ml$) significantly ameliorated ethanol-induced LTP and NMDA receptor-mediated synaptic transmission in the hippocampal slices. EHDF prevented ethanol-induced object recognition memory deficits induced by ethanol. Interestingly, EHDF significantly ameliorated ethanol-induced LTP and NMDA receptor- mediated synaptic transmission in the hippocampal slices.
