Indoor radon($^{222}Rn$) concentrations of subway stations in Seoul area were measured to survey the environmental indoor radon levels and to identify sources of radon. The radon concentration of indoor air by method of long-term measuring with a-track detector were surveyed at 232 subway stations from 1998 to 2004. And the radon concentration in ground-water was measured with a method of alpha particle counting. To trace main source of radon, 8 out of 232 stations were selected and their radon concentrations in tunnel and on platform were analyzed. Total geometric mean and arithmetic mean of radon concentrations in all stations from 1998 to 2004 were $1.40{\pm}1.94pCi/L,\;1.65{\pm}1.07$ respectively. Geometric means of radon concentrations on platform and concourse were $1.54{\pm}1.96pCi/L,\;1.23{\pm}1.88pCi/L$ respectively, with higher concentration at the platform than at the concourse. The geological structure was significantly correlated to the indoor radon concentration in subway stations region. Radon concentrations of adjacent tunnel and ground-water of subway station was significantly correlated to the indoor radon concentration in subway stations. And There was a significant difference in radon concentration, depending on the depth levels in platform of subway stations(p<0.05).

In order to monitor internal risk factors such as fire, terror, etc. on the subway station, the surveillance systems using CCTV and various kinds of sensors have been implemented and recently, introduction of surveillance systems using an advanced IT technology, sensor network technology is tried on several areas. Since 2007, Korean government has made an effort to develop the intelligent surveillance and monitoring system, which can monitor fire, intrusion, passenger congestion, health-state of structure, etc., by using wireless sensor network technology and intelligent video analytic technique. For that purpose, this study carried out field wireless communication environment test on Chungmuro Station of Seoul Metro on the basis of ZigBee that is considered as a representative wireless sensor network before field application of the intelligent integrated surveillance system being developed, arranged and analyzed and ZigBee based wireless communication environment test results on the platform and waiting room of Chungmuro Station on this paper. Results of wireless spectrum analysis on the platform and waiting room showed that there is no radio frequency overlapped with that of ZigBee based sensor network and no frequency interference with adjacent frequencies separated 10MHz or more. As results of wireless data transmission test using ZigBee showed that data transmission is influenced by multi-path fading effect from the number and flow rate of passengers on the platform or the waiting room rather than effects from entrance and exit of the train to/from the platform, it should be considered when implementing the intelligent integrated surveillance system on the station.

5만년인가, 4천년인가. 문화재청은 지난 2월 6일 제주도 남제주군 대정읍 상모리와 안덕면 사계리 해안에서 사람 발자국 화석 100여 점과 동식물 화석 수천점을 발견했다고 발표했다. 화석 발견 지층의 생성 시기는 구석기 중기인 5만년전으로 추정되며 선사인류 발자국 화석은 한국교원대 김정률 교수팀이 지난해 10월 처음 발견했다. 경북대 양승영 명예교수는“사람 발자국 화석은 재주도를 포함한 한반도와 중국 대륙이 육로로 연결됐다는 가설을 뒷받침해주는 증거물”이라는 견해를 밝혔다. 선사시대 인류발자국의 발견은 세계에서 7번째이며 함께 발견된 코끼리와 말 발자국은 당시 한반도가 온대 지역이 아닌 아열대 지역이었을 가능성을 제기했고, 말의 기원이 몽골에서 유래되었다는 기존 주장을 바꾸는 계기가 될 것으로 보인다. 그러나, 화석 발자국 발표 이후, 관련학자들간에 이견이 생겼다. 일부 학자들이 연대측정에 의문을 제기하고, 제주도 지층은 4천년 전에 생성된 것이며 ‘5만년 전 추정’에는 무리가 있다는 지적이었다. 한 인류의 이동을 추정하는 데는 5만년 전과 4천년 전은 엄청난 역사적 차이가 있다. 아프리카 대륙에서 시작 된 인류의 조상이 중국과 북방육로를 통해 한반도까지 이동해왔다는 지금까지 학계의 통설은 뒤집힐 것인가. 제주도의 사람 발자국 화석은 그 절대 연대가 정확히 측정된다면 한반도 인류의 일부가 중국 남방의 육로나 해로를 통해서 이동해왔을 가능성이 있다는 새로운 사실을 밝혀줄 것이다. 현대 과학이 연대측정기술을 발달시켜서 역사를 풀어나가기 시작한 것은 겨우 50여년 전으로 일천하기만 하다. 그러나, 그 학문의 깊이는 지구 나이 45억년을 밝혀냈고, 35만년 전 유기물의 생성을 추정해내는 등 심오한 경지에 이르고 있다. 현대과학의 연대측정방법론을 소개한다.

This paper studied on the geographical distribution location arrangement and the social construction of Pungsu discourse and the Pungsu(Fengshui) management of royal tombs on the Joseon Dynasty from the historical, cultural geographical perspective. The Pungsu landscape of royal tombs during the Joseon dynasty was the direct result of the political dynamics among the king, his family, other royal families, and various groups of vassals. Pungsu was a important factor in deciding tomb sites or landscapes, but it was a secondary factor to politics in the Joseon Dynasty. The primary factor was politics, clearly showing Pungsu's status in social discourse. The royal tomb Pungsu is defined as the Pungsu discourse of the Joseon Dynasty period which is combined with Confucian ideology in Korean Pungsu history.

The history of Chechnya is characterized by the resistance against the invasions of different foreign countries. Among them, the conflict against the Soviet Union, or Russia has been lasted approximately 200 years and it still remains unsettled. The relation between both country was deteriorated when the Chechnya declared their independence from Russia, and this resulted in the long-lasted war between Russia and Chechnya. One of the driving force of the war for Chechnya was its religion, Islam. The Islam and the brotherhood of Sufi Islam are integrated with Chechen nationalism and they were the key factors during the war against Russia. In this present paper, we will deal with the Chechen national culture and its identification, the conflict history of Chechnya-Russia, Islamization of Chechen, and the power of Sufi Islam in Chechnya in order to give a careful consideration to the conflict between both countries.

China government recently tries to preserve not only the famous national historic-culture cities, but also the small and medium-sized cities due to the damages and destruction of the cities by the rapid economic development, urban expansion and the development of tourism industry. Hence, this study chose 'Zhoucun ancient mall' which is one of the hotness of cultural heritage located in a mid-sized city named 'Zhoucun district Zibo city Shandong province' that has continuously cared historical landscapes by the protective policy regarding the city as a historic-culture resource from '80s, and considered the character of the city's development process on how the historical landscapes were well protected. In fact, the protection policy in Zhoucun ancient mall had been started in early '80s, however, the viable plan was established in 2001 entitled 'Historical block protection planning of Zhoucun Da street'. And then, 'Regulatory plan for the ancient mall site of Zhoucun Da street' established in 2008 has expanded the area of the blocks for protection. However, this plan organized area only block-by-block so that the small blocks couldn't have the unity when expanded. Later in 2015, 'Regulation Organization Plan' hastried to expanded the protect-area to solve the unity problem. As a result of the study, the historical landscape management plan of Zhoucun in Zibo city has been systematically changed in 2001 after. In other words, this 2001's plans established buffer zones for the maintenance of protected areas and the surrounding environment. And then the detailed regulatory plan for 2008 led to a concrete urban management plan. After that, in 2015, it was found that the expansion plan to protect and manage the whole area of Zhoucun disrict is to manage the landscape of the surrounding area including the historical landscape of 'Zhoucun ancient mall'.

We now live in the new era of globalization which implies the functional integration or increase of inter-dependency between internationally dispersed economic activities. As globalization impacts our various activities and daily lives, social sciences, including, geography, attempt to approach social phenomena from a global perspective. From this point of view. new regional geography, which has been articulated in recent social theory since the 1980s, also must adjust to these new world realities. This paper aims to search for a suitable methodology or approach to area study or regional geography in the era of globalization and to suggest the field of area study that Korean geographers should be concerned with in the future. This paper has reviewed the existing various methodologies of regional geography such as the ecological approach, the landscape approach. the areal differentiation approach, the system approach, the structuration theory, the spatial division of labour, and the world-system, which have deviced in the traditional and new regional geography. Peter Taylor's regional geography of world systems among them has an appropriate rationale of area study in the globalization era, because world-systems theory explains well globalization. However the regional geography of world-systems must be revised to become more suitable to the area-study approach in the globalization era. Firstly, the regional geography of world-systems explains that regions(historical regions) are made by general mechanisms of the capitalist world-economy that operate through social, economic, and political agents within regions such as individuals, households, social classes, economic enterprises, states, political movements, and many other organizations. But these mechanisms can also act through other regional agents of geographical location, natural conditions, and cultural characteristics. Therefore, the generating process of regions needs to be explained by locational, natural, and cultural elements in addition to social, economic, and political elements within regions. Secondly, Taylor's world-systems approach does not express composite characteristics of regions, because it focuses on the economic characteristics or position of regions within the world-economy. Regions incorporated into world-economy systems are not only changed economically, but also changed spatially, socially, culturally, and politically. Hence the world-systems approach must try to analyze these composite characteristics and their change of regions. Thirdly, The world-system approach proposed that the geography of regions within world-systems could be divided and analyzed as three regional types at the geographical scale such as international regions, state regions, and intra-state regions. However such a regionalization is usually not identified distinctly, because the geographical range of regions in world-systems shaped by economic boundaries of the general mechanisms of the world-economy is fluid and also occasionally overlaps with other political regions. Hence I propose that the world-systems approach should choose political boundaries of states and local autonomies in addition to economic boundaries for objective regionalization and systematic areal study. The revised regional geography of world-systems that I have suggested in this paper can be more effectively and properly applied to regional geography or area study in the globalization era. Globalization intensifies competition between states and also between local autonomies in the world. Therefore we must make efforts to study such areas or regions through the revised regional geography of world-system.

The core idea of the critical regionalism could be summarized as a self-conscious synthesis between universal civilization and world culture. After World War II, it has been applied to architecture for overcoming the problem of Industrial Capitalism and uniformity of 20th century Modern Architecture. Naturally, religious architecture cannot also be an exception in this cultural trend, thus we can also apply the critical regionalism to the Korean Catholic Church Architecture with the basic premise that the Traditional Western and Modern Style Church Architecture should be regarded as universal civilization, and the Traditional Korean Architecture and endemicity as one of world culture. In the context, this article attempts to analyze the regionality of Korean Modern Catholic Church Architecture constructed between the 19th century and 1980's, and how it has been differently transformed with the view of the critical regionalism. Its analysis will be carried out within three types; transformation of the Traditional Korean Architecture and the influence of Japanese Modern Architecture, representation of the Traditional Korean Architecture, and abstraction of the Traditional Korean Architecture with each advantages and disadvantages.
