  • This study suggests that the contents and methods focusing on the leamer's geographical experience of everyday life and environments, are very effective for teaching and teaming in geography subject matter. The contents have to be selected and structurized from private geographies about their region of everyday life for teaming abstractive and scientific concepts of geography. Scientific concepts of geography, i.e. geographical concepts become 'scope'for selecting the contents and these systematic structure substitutes 'sequence'. The criteria by which selected contents of teaching and teaming based on everyday life may consist of three elements: region as leamer's place for everyday life; concrete experience of the place; and leamer's changing geographical experiences.

  • This study investigates the effect of GIS-integrated lessons on spatial thinking abilities and geographical skills using discourse analysis along with a comparative three-case case study method. A series of curricula were designed and implemented in an 8th grade classroom for a semester. The data collected consist of the dialogue transcripts of six consecutive GIS-integrated lessons. The transcripts were analyzed to identify the moves (speech acts) used by each student and to classify discourse content of spatial thinking and geographical skills. Based on three individual case studies, a cross-case study was performed to uncover any relationship between the phenomenon and the contexts. The empirical evidence from discourse analysis demonstrated that students were able to generate appropriate terms representative of spatial thinking and geographical skills although students appeared to possess primarily lower-order spatial abilities, followed by a moderate-level of spatial abilities. Considering that the unit was implemented in a biology class rather than a geography class the result reflected the fact that the student's spatial thinking and geographical skills were attributable to the GIS-integrated lessons. Thus, the results have a great implication for GIS-integrated lessons and geography education as an innovative tool for improving student's spatial thinking and geographical skills.

Organisational Change, Learning and the Usage of Space: the Case of Samsung Electronics Company (기업의 조직변화와 학습의 공간성: 삼성전자의 사례)

  • This paper aims to explore organisational change and learning involving spatial processes and outcomes. In particular, it focuses on the context specific nature of corporate learning and organisational change that can be found in the case of a large Korean firm facing radical economic change. Drawing on the case study of a large Korean firm, the Samsung Electronics Company, three main claims can be followed. First, territorial sources of learning influence the way in which the firm makes use of space/place. Second, corporate learning practices, however, are not based merely on specific localised sources or geographical proximity but on bringing together the local and the global sources by harnessing the properties of relational proximities. It reveals that firms are concerned less on specialising specific local knowledge than promoting organisational knowledge and competences by integrating a variety of knowledge distributed in and out of the boundaries of the firm. Finally, to learn and innovate in a continual basis, firms would attempt to combine codified knowledge with tacit knowledge.

  • Public policy responses to the digital/information revolution and the micro-economic reforms that it facilitates have inspired exploration of the scope for local government implementation of digital spatial data handling(DSDH) of information relating to, among other things, asset inventory, environmental and utility management, address management, and planning. The results from these explorations are such that few doubt the value of bringing the public policies to practice, but diffusion rate and pattern of the approaches demonstrated by the scoping experiments will reflect institutional/cultural matters, indicators of the relative significance of which might be at least partly predicted from appraisal of case studies. This argument is exemplified by reference to case studies in adoption of DSDH by local government organizations in Korea and in Australia.

  • Geographical isolation may lead to the populations having different ecological characteristics. Geographic isolation have been known to cause echolocation call differences in bats. In order to look at geographic differences of echolocation calls of Great Horseshoe Bats (Rhinolophus ferrumequinum), populations of inland and Jeju island habitats were examined in Korea. The study areas were some abandoned mines in the inland and caves of Jeju island, which were known as rest sites of Great Horseshoe Bats during the active season. Recording was done in two ways: Hand-held, Free-flying. Recording pulse was analyzed into five parameters: Maximum Frequency (FMAX), Minimum Frequency (FMIN), Peak Frequency (PF), Duration (D), Inter pulse Interval (IPI). Interestingly, The present study shows that the difference in echolocation between the inland and island populations. The PF of bats inhabited inland was 69 kHz. but, the PF of bats inhabited island (Jeju) was 71 kHz. There was a difference between regions. Discriminant analyses also showed clear difference between the inland and the island populations. Especially, PF of Korea population is lower than that of Europe (82 kHz) and higher than that of Japan (65 kHz).

  • 이 논문은 뉴질랜드를 사례로 인간이 육지와 해양을 이용함에 따라 미치게 되는 근본적인 지리적 문제들을 자세히 살피고자 한다. 환경적 갈등은 토지자원과 수자원에 대한 인간의 요구와 필요에서 비롯된다. 뉴질랜드에서는, 자연자원 이용의 갈등을 체계적으로 다루기 위해 1991년에 자원관리법을 제정하였다. 클린턴대통령 자문회가 이 법안과 지속가능한 개발을 검토함으로써, 이 법안은 선도적인 환경관련 법류? 하나로서 국제적인 중요성을 갖게 되었다. 이 논문에서는 다양한 사례연구를 통해서, 이 자원관리법이 뉴질랜드 자연자원의 높은 질을 유지하고 보호하고자 했던 소기의 성과를 거두었는지에 대해 논의하고자 한다. 이러한 논의에서 핵심이 되는 것은, 자연환경에 대한 문화적인 가치와 태도, 그리고 이러한 것들이 자연환경의 이용에 어떻게 영향을 주는지, 또한 자원관리법이 자연자원의 이용에서 발생하는 갈등을 어떻게 조절할 수 있는지에 관한 것들이다.

  • 설악산의 교목한계선, 왜성변형수, 편형수, 포복형 나무 등 기형 수목 형태는 아고산대의 생태적 점이대에 나타나는 식생 경관으로 지생태학적으로 중요한 자연유산이다. 아고산대의 기형 수목 형태는 주로 저온, 강풍, 건조 그리고 적설 등 겨울 기후와 관련되지만 다른 계절과도 관계된다. 설악산의 눈잣나무는 세계적 분포 남한계선으로 생물지리적으로 가치가 높으며, 아고산 환경에 적응한 독특한 외관형을 나타낸다. 설악산 아고산대의 식생과 경관은 과거의 자연환경 변천사를 복원하고, 현재의 환경을 이해하고, 미래의 환경 변화의 영향을 파악하는 지표로서도 중요한 자원이다. 차후 환경 변화에 따른 설악산 아고산대의 식생과 경관의 변화에 대한 중장기적인 모니터링이 요구된다.

  • Even though rarely recognized as a separate approach, the institutional approach in geography is defined as an attempt to seek an explanation of the phenomena of geographical interest through focusing on the effects of institutional structure and actions. It can provide interdisciplinary links with other works and can offer complementary explanations for geographical interests. The concerns for institutions in geography can be found in early studies, the study of the state, the managerial approach, and the regulation approach. The Korean financial systems can provide good examples to apply institutional concepts into creating spatial outcomes, as it has been regarded as a useful tool to promote Korean economic development. Behind the current spatial pattern of financial systems, four different stages of institutional changes are identified in Korea. Each stage has different institutional features reflecting unique spatial implication.

  • In this study, we investigated the effect of geographical variations on Sargassum thunbergii morphology to make a taxonomic reconsideration about infraspecific taxa in this species. In order to examine the morphological characteristics of S. thunbergii, total 27 matured and morphologically intact thalli were collected from the east, west and south coast in spring 2011. Interestingly, it was observed that the species populations on the west coast were characterized by short, thin and coarse thallus, and soft texture. However, the populations on the east coast showed thicker thallus, larger leaf and vesicle, and tougher texture. Thallus height of S. thunbergii was found to be similar at both east and west coast. Further, the height of the thallus and lateral branch of the species populations residing south coast were highest whereas the size of leaf and vesicle are shortest, in comparison with east and west coast species. Although morphological characteristics of the north east coast populations corresponded to the original description of S. thunbergii f. latifolium, we could not find exact morphological features and diagnostic characters to distinguish form in S. thunbergii. These results indicated that it is not the optimal characteristics to identify infraspecific form in this species. In contrast, morphological variations may signify the adaptation of this species to local environmental factors. Thus, we recommend that intraspecific morphological variation of S. thunbergii should be carefully used to identify infraspecific taxa.
