복합과학으로서의 자연지리학, 진화생물학과의 만남, 생물지형학으로의 승화

김대현,김혜진,박건우,고희종 대한지리학회 2025 대한지리학회지 Vol.60 No.1

본 논문에서는 우리나라 지리학계에 생물지형학을 정식으로 소개한 김대현(2021)의 내용을 확장하여, 생물지형학의 학문적 근원을 이해하고 향후 나아갈 바를 모색하였다. 이를 위해, 세 가지 세부 목적을 다루었다. 첫째, 자연지리학이가지는 ‘복합과학’으로서의 성격을 논의하였다. 토마스 쿤의 범례(範例) 개념을 바탕으로, 자연지리학이 기초과학에서 차용한 원리를 통해 발전해 온 역사를 조망하였다. 둘째, 지형학, 토양학, 생태학 등 자연지리학의 세부 혹은 연관 분야에서생물지형학의 태동에 영향을 준 인물들의 학문사적 발자취를 파악하였다. 이들의 주요 연구가 현재와 미래의 생물지형학에 제공하는 함의를 확인하였다. 셋째, 자연지리학자들이 진화생물학적 시각을 채택함으로써 수행할 수 있는 생물지형학적 연구의 가능성을 탐색하였다. 특히, 생물과 환경의 공진화 되먹임 작용을 연구하기 위한 가설을 제안하였다. 궁극적으로, 우리나라 자연지리학의 가치와 지평이 생물지형학적인 연구를 포용・확장함으로써 고양될 수 있음을 강조하였다. In this paper, we aimed to expand on the work of Kim (2021), who formally introduced biogeomorphology to the field of geography in Korea. Our goal was to deepen the understanding of the academic roots of biogeomorphology and explore future directions for the discipline. To this end, we addressed three specific objectives. First, we discussed the complex nature of physical geography as a multifaceted ‘composite science’. Drawing on Thomas Kuhn's concept of paradigms, we reviewed the historical development of physical geography through principles borrowed from the foundational sciences. Second, we identified the scholarly legacies of influential figures in related fields, such as geomorphology, soil science, and ecology, who have impacted the emergence of biogeomorphology. We examined how their major research contributed to the current and future implications for the discipline. Third, we explored the potential for biogeomorphological studies that can be conducted by physical geographers adopting an evolutionary biological perspective. In particular, we proposed three hypotheses for investigating the coevolutionary feedback mechanisms between organisms and their environment. Ultimately, we emphasized that the value and horizons of physical geography of Korea can be enhanced by embracing and expanding biogeomorphological research

The purpose of this study was to suggest a case study and anlaysis of the visual impact in dam construction through visual impact assessment method in Dong-sang river. The results can be summarized as follows; 1) For the evaluation of the visual impact of dam construction, five steps such as field analysis of visual status, finding visual sensitivity area and visual control point, making visual simulation material and evaluation, and visual impact analysis and assessment were suggested as desirable. 2) In the case study, the visual impact of dam construction was evaluated to be simple, unique, modern, static, cool and unfamiliar. 3) There was a few difference between the pre-construction and post-construction in statistical test. Especially, The dam in Man-Jee area was evaluated to be artificial, unique and destroyed in statistical difference, and then we design dam structure with visual friendliness. 4) In conclusion, there was high correlation between pre-construction landscape and post-construction landscape through semantic differential scale method using eleven adjectives. Therefore, we state that there is no visual impact for the dam construction for the moment.

The purpose of this study was to investigate factors and variables which have significant effects on satisfaction of urban pedestrian sidewalk in taejon city, and to suggest basic information for urban pedestrian sidewalk. These works consist of two phase; The first, tested the user's degree of satisfaction for 37 spots of pedestrian sidewalk slide and then selected 10 spots slide by the stratified random sampling method. The second, analyzed factors and variables of satisfaction of urban pedestrian sidewalk using the semantic differential scale method, and then processed by mean score, correlation, factor analysis, multiful algorithm. The results were summarized as follows; 1) The relationship between the man group and the woman group was highly correlated as well as between the student group.1 and the student group.2 hense these groups statistically showed no difference in satisfaction ratings. 2) Pedestrian sidewalk width, cleanness, pavement materials and construction condition can be significant variables of satisfaction of urban pedestrian sidewalk. 3) Factors covering the satisfaction of urban pedestrian sidewalk have been found to be Environment of pedestrian sidewalk, Vegetation of pedestrian sidewalk and Form of pedestrian sidewalk. By using the control method for the number of factors, C.P. has been obtained as 62.8%.

폐 악성 섬유성 조직구종 -1예 보고-

김대현,박주철,김중헌,김범식 대한흉부외과학회 2007 Journal of Chest Surgery Vol.40 No.11

원발성 폐 악성 섬유성 조직구종은 매우 드문 종양이다. 12세 남아가 우연히 발견된 폐 종괴를 주소로 입원하였다. 흉부 X-선, 흉부 전산화 단층촬영, 양전자 방출 단층촬영에서 우하엽에 위치하는 2.5×2.5 cm 크기의 종괴가 관찰되었다. 우측 측방 개흉술을 통해 종괴를 절제하여 냉동 절편 조직검사를 시행한 결과 악성 방추형세포 종양으로 진단되었다. 따라서 우하엽 절제술 및 종격동 림프절 청소술을 시행하였고, 최종 조직학적 진단은 악성 섬유성 조직구종이었다. 환자는 수술 후 7일째에 퇴원하였으며, 보조적 항암 약물치료는 시행하지 않았다.

분석 투과전자현미경을 이용 ZnO바리스터의 계면을 관찰하였다. 바리스터 특성의 조성물에서 Bi_(2)O_(3) 의 함량을 바꾸어 바리스터를 제조하여 이들의 전기적 특성을 측정하였고 또한 입계구조와 전기적 특성과의 관련성을 규명하기 위해 입계에 대해 분석 투과전자현미경을 이용 입계를 관찰하였다. 전기적 특성의 변화는 Bi_(2)O_(3) 의 함량 변화에 민감하였으나 입계구조의 변화에서는 분석 범위내에서 변화를 관 찰 할 수 없었다. Even though most die-maker are using CAD/CAM systems for NC tool-path generation, "frontend" CAD/CAM technologies have not been fully adapted to sculptured surface machining(SSM) nor are sufficiently utilized in die shops. This gap between die-making industry and CAD/CAM community persists mainly because of the lack of a SSM-process model through which the two groups communicate with each other. Proposed in this paper is a model of SSM-processes which is built around the concepts of machining stages, unit machining operations, and each machining stage is decomposed into a sequence of unit machining operations(UMOs). Identified in the paper are five machining stages and 17 types of UMO. Based on the framework of the proposed model, an example of inner-panel stamping-die machining processes is described in detail.

In this paper, articulatory simulator 'Artsim' is used as a tool for the experiments to examine the articulatory characteristics of 6 different vowels. Each vowels are defined by some articulatory points from their vocal tract area functions and shapes of tongues. Each points are varied systematically to synthesize vowels and the synthesized sound is evaluated by human listners. Finally distributions of each vowels within vowel space is obtained. From the experimental results it is verified that our articulatory simulator can be used effectively to investigate the articulatory characteristics of speech.
