인류의 역사는 태풍, 지진, 해일, 홍수 그리고 가뭄 등과 같은 자연재해와의 끊임없는 투쟁으로 점철되어왔다. 최근 들어 지구 온난화는 인류의 생존에 커다란 위협으로 대두되었다. 우주시대에 접어들면서 인간의 활동은 지구 대기권 밖으로까지 확대되면서 인간의 사회 경제적인 활동이 인공위성을 위시하여 매우 정밀한 기기에 의존하게 되었다. 그러나 인공위성과 더불어 현대사회를 지탱하는 전력, 통신, 운송 등과 같은 사회기반시설들은 태양활동에 매우 취약하다는 점이 확인되었다. 태양에서 플레어나 CME가 발생하면 X-선 복사와 더불어 고에너지 하전입자가 방출되면서 지구주변 우주환경에 급격한 변화가 일어난다. 이 기간 동안 인공위성, 전력, 통신, 항법 등이 영향을 받아 다양한 사회 경제적인 손실이 유발된다. 따라서 태양활동으로 인한 이들 시설의 붕괴 내지는 기능 저하는 현대사회의 근간을 훼손하는 이제까지 경험하지 못했던 새로운 형태의 자연재해가 될 것이다. 이 논문에서는 역사적으로 우주환경의 급격한 변화가 야기한 문제점들을 살펴보고 태양활동이 장래에 인류의 삶에 어떠한 영향을 미칠지를 전망하고자 한다.

The purpose of this study is to investigate sensibility words related with eco-friendly in the two media fashion magazines and internet newspapers and to analysis their appearance frequency and changes by the year through 1999~2010. Most frequently used words are 'nature, eco, cotton, natural fiber, health, fresh, clear, preservation, harmony, com fiber, and Lohas'. The words are divided in 4 groups: 'Nature/Environment, Material/Fiber, Human, and Adjectives/Micell'. A point of appearing time is analyzed: 'ecology, memory-shape material, organic, spa' were used before 2000, 'nature environment, eco-friendly, stretch material, wellbeing, substitute, recycling' were in 2000-2001, 'smart material, eco material, green' in 2002-2003, 'coolbiz, Lohas, natural dye' in 2004-2005, 'herb medicine, sustainable, warmbiz' in 2006-2007, 'greensumer, greenlife, solar energy, forest bath' in 2008-2009. Looking into their changes, in early 2000, the words of eco-friendly emotion and sensibility had appeared frequently relatively, but later on they decreased, and again recently increased showing highest appearing frequency. 'Nature/Environment' words have appeared recently very much, while 'Human' sensibility words have not changed much or decreased a little. 'Adjective/Micell' words has increased little bit recently. 'Material/Fiber' words showed decrease at fashion magazine, while they increased at the pages of internet news.

There has been a tendency for Geomorphology and Climatology to be dominant in Physical Geography for 50 years in Korea. Physical Geography is concerned with the study of the totality of natural environment through the integrated approaches. But, an overall direction or a certain paradigm could not be found, because major sub-divisions of Physical Geography have been studied individually and the subjects and the approaches in studying Physical Geography are enormously diverse. A consensus of opinion could not also exist in deciding what kind of the sub-divisions should be included in the physical geography in general and how those should be summarized. Furthermore it would be considered imprudent to survey the studies of Physical Geography besides those of Geomorphology and Climatology due to the small number of researchers. Assuming that the rest of Physical Geographical studies with the exception of Geomorphological and Climatological studies are the Physical Geography in general, the studies of Physical Geogrpahy in general are summarized and several aspects are drown out as follows. First the descliption of all possible factors of natural environments was the pattern of early studies of Physical Geography and the tendency is maintained in the various kinds of research and project reports. Recently Physical Geographers have published several introductory textbooks or research monographs. In those books, however, the integrated approaches to Physical Geography were not suggested and the relationship between man and nature are dealt with in the elementary level. Second, the authentic soil studies of Physical Geographers are insignificant, because the studies of soil in Physical Geography have been mostly considered as the subsidiary means of Geomorphology Summarizing the studies of Soil Gegraphy by physical geographers and other Pedologists, the subjects are classified as soil-forming processes, soil erosions, soil in the tidal flat and reclaimed land, and soil pollution. Physical Geographers have focused upon the soil-forming processes in order to elucidate the geomorphic processes and the past climatic environment. The results of other subjects are trifling. Thirdy Byogeygrayhers and the results of studies are extremely of small number and the studies of Biogeography in Korea lines in the starting point. But, Biogeography could be a more unifying theme for the Physical-human Geography interface, and it would be expected to play an active part in the field of environmental conservation and resource management. Forth, the studies of Hydrogeography (Geographical Hydrology) in Korea have run through the studies of water balance and the morphometric studies such as the drainage network analysis and the relations of various kinds of morphometric elements in river. Recently, the hydrological model have introduced and developed to predict the flow of sediment, discharge, and ground water. The growth of groundwater studies is worthy of close attention. Finally, the studies on environmental problems was no mole than the general description about environmental destruction, resource development, environmental conservation, etc. until 1970s. The ecological perspectives on the relationship between man and nature were suggested in some studies of natural hazard. The new environmentalism having been introduced since 1980s. Human geographers have lead the studies of Environmental Perception. Environmental Ethics, Environmental Sociology, environmental policy. The Physical geographers have stay out of phase with the climate of the time and concentrate upon the publication of introductory textbooks. Recently, several studies on the human interference and modification of natural environments have been made an attempt in the fields of Geomorphology and climatology. Summarizing the studies of Physical Geography for 50 years in Korea, the integrated approaches inherent in Physical Geography disappeared little by little and the majol sub-divisions of Physical Ceography have develop in connection with the nearby earth sciences such as Geology, Meteorology, Pedology, Biology, Hydrology, etc been rediscovered by non-geographers under the guise of environmental science. It is expected that Physical Geography would revive as the dominant subject to cope with environmental problems, rearming with the innate integrated approaches.

In this paper we present a hybrid model that enables dynamic regrouping based on emotion in determining the behavioral pattern of crowds in order to enhance the reality of crowd simulation in virtual environments such as games. Emotion determination rules are defined and they are used for dynamic human regrouping to simulate the movement of characters through crowds realistically. Our experiments show more natural simulation of crowd behaviors as results of this research.

지역이나 국가에 따라 사람들의 색채감성에는 조금씩 차이가 있다. 색채감성에 영향을 미치는 자연환경의 요소로는 생태조건, 기후조건, 자연광조건 등으로 나뉘며, 자연광조건은 자연광의 세기와 색온도, 생태조건은 토양과 식생, 기후조건은 온도와 습도, 쾌청지수 등으로 나눌 수 있다. 이들은 인간이 지각하는 색의 색상·명도·채도와 관련을 갖고 있다. 각 지역의 풍토조건의 차이로 생기는 색채감성의 구조를 자연광의 세기에 따른 명도 변화, 대기중의 습도에 따른 채도변화, 온도차에 따른 색상변화로 나누어 파악하였다. 또한 한국과 일본을 사례로 풍토색과 도시환경색채를 통해 색채감성의 차이를 비교하여 분석하고 그 주원인을 파악하여 지역별 색채 감성을 분석하는 기틀을 마련하고자 한다.

기후와 인간 활동의 변화는 하천의 유량을 변화시키는 중요한 요소들 중 하나이다. 하천관리를 위해서는 이 요소들의 긍정적인 영향과 부정적인 영향이 하천에 얼마나 많은 영향을 끼치고 있는지 수치화하여 관리해야한다. 또한 상류에서의 기후와 인간 활동에 의해 변화된 유량은 하천 하류까지 전달되어 적지 않는 영향을 미치고 있다. 효과적인 하천관리를 위해서는 유역 내 기후와 인간 활동에 의해 변화된 유량과 하류하천에 미치는 영향을 정량화하여야 한다. 본 연구에서는 하천에서 기후와 인간 활동에 의한 유량 변화를 정량화 하고 그 요소들이 상류에서 하류에 얼마나 많이 전달이 되는지 분석하였다. 본 연구 결과 수리구조물이 설치되어 있는 하천에서는 인간 활동에 의한 유량변화량이 크게 나타났다. 상류의 수리구조물에 의한 영향은 하천 하류에도 크게 전달되는 것으로 분석되었다. 또한 기후적인 요인에 의해 유량의 변화가 큰 지역은 그 외 지역보다 자연 재해에 의한 피해 위험도가 높다고 판단된다. 본 연구의 결과는 미래의 효과적인 수자원관리를 결정하는데 중요한 정보를 제공해줄 수 있을 것이라 기대된다.

The assessment of perceived naturalness aims to elucidate the human perception and explain the interaction between natural environments and humans. The perception of ecological assets that exhibit distinct characteristics within a specific region can manifest in various representations. Based on the users' perceptions and interviews regarding ecological assets, this study assessed the perceived naturalness from a cultural services perspective. Specifically, the discussions on Ansan City's ecological assets and revolved around the inherent value of naturalness in dimensions, such as the necessity for conservation and the sustainable development of ecological assets, the perception of ecosystem benefits, the representativeness as a local asset, and usability. Subsequently, the Q method was employed to present 25 representative ecological assets to 25 users. As a result, user groups with different value systems for each question were identified, and hypothetical personas for cultural service enjoyment were distinguished. The most representative persona among the 25 users was identified as AWP (a type that values the conservation of aquatic ecosystems, prefers waterfront landscapes, and enjoys walking). Since perceived naturalness is conceptually similar to the "benefits perceived by users" in evaluating ecosystem services, it can provide more practical evaluation criteria for cultural services.

본 연구의 대상해역은 여수반도 남단에 위치한 가막만은 굴을 비롯한 패류양식 생산활동에 기여하는 자연환경의 실질적인 가치와 인간경제 시스템에 대한 EMERGY 분석법으로 평가하고자 한다. 이를 기초로 넙치생산의 지속적인 발전방향을 제시하고자 했다. 2004년 통계를 기준으로 가막만 양식에 유입되는 총 EMERGY의 양은 33.42E+19 sej/yr이고, 이 중 자연환경으로부터 영속성 에너지는 2.95E+20 sej/yr 이며, 주 경제로부터 유입되는 비영속성 에너지는 3.92E+19 sej/yr이다. 자연환경으로부터의 유입이 전체 에너지원의 88%이고, 주 경제로부터의 유입은 12%로서 환경자원에 대한 의존도가 높은 1차 산업의 구조적 특징을 나타내고 있다. Net EMERTY yield ratio는 8.52으로 이는 주 경제로부터 투입된 에너지(비영속성 에너지)에 대해 8배 만큼 수산물을 얻을 수 있는 자원으로서의 가치를 가진다. EMERGY Investment Ratio 0.13은 주 경제로부터 유입된 에너지의 약 7배에 해당하는 에너지를 자연환경에서 얻을 수 있음을 의미한다. EMERGY량이 모두 현재의 EMERGY 생산비대로 생산이 된다는 가정하면 가막만의 패류(굴) 생산량은 환경수용량의 50%정도에도 못 미치는 것으로 나타났다.
