논산지역의 간이상수도 수질을 모니터링한 결과 약 13-21% 정도가 간이상수도 수질기준을 초과하는 것으로 확인되었으며 그 원인은 주로 질산성질소, 탁도, 일반세균 등에 의함을 알 수 있었다. 연구지역의 지하수 수질에 영향을 미치는 인자를 정량적으로 해석하기 위하여 토지이용도, 토양도 및 지질도를 작성하여 판별분석을 수행하였다. 판별분석 결과 지하수 수질과 지질은 겉보기 오차율이 5.56%로 매우 밀접한 상관성을 나타내었으나 토지이용과는 52.63%로 상관성이 없는 것으로 나타났으며 이는 점오염원의 효과를 고려하지 못하였기 때문으로 사료된다. 토양특성과는 오차율이 13.16%로 비교적 잘 일치하는 결과를 보여주었으며 이는 토양발달이 지질과 밀접한 상관성을 가지기 때문으로 판단된다.

GIS was appl ied for analysis of the potfnt ial degree of regional geologic hazard, expecially landslide, in the suburb of Seoul city. Potential elements causing a landslide are geology, slope geometry, groundwater, soil property, rainfall and vegetation etc. These factors were incorporated through GIS in order to predict the potential hazards, and to produce a regional geologic hazard map in the study area, For this study, ARC/INFO and ERDAS systems were used in SUN4-390 workstation.

공학지질도(Engineering geology map)는 토목공사의 예비단계에서 필요한 지질자료를 도면에 표시하여 지질공학 계획(Engineering geological plan)의 수립과 토목설계 정보를 제공 위하여 작성하는 특수지질도이다. (Report by the geological society engineering group working party, 1972). 공학지질도에는 지질공학, 토목 또는 건축 기술자들이 필요로 하는 지질정보를 수록하기 때문에 기존의 지질도(Geological map)와는 다르게 작성한다. 즉, 지질도는 암석의 광물조성, 석기 (texture), 층서, 지질구조 등의 지질학적 분석을 통하여 지각의 생성 메카니즘과 지구의 역사를 규명하는 것이 궁극적 작성 목표이다. 따라서 지질도에는 공학기술자들이 필요로 하는 암석과 토층의 물리적/공학적 특성이나 지하수에 대한 정량적 정보 등이 수록되지 않을 뿐 아니라 공학기술자들에게 필요한 인간 생활권 부분인 지표와 천부의 지질학적 특성이 제외되는 경우가 많다.

지구상의 광물, 암석, 화석 그리고 지질구조, 지형 등의 개개의 지형 지질학적 요소의 특성과 다른 대상과의 상호관계를 지질다양성이라고 한다. 지질다양성은 지형 지질에 내재되어 있는 본질적, 문화적, 심미적, 경제적, 기능적, 연구 및 교육적 가치를 이해하고 보전함으로써 유지 할 수 있다. 이 연구는 지질다양성에 대한 흥미와 이해를 높이기 위해 학술적 보전 가치가 있는 강원도 영월지역을 선정하여 그 특징을 분석하고 지질다양성을 효율적으로 활용하는 방안을 제언하고자 한다. 강원도 영월지역의 지질다양성에 대한 조사는 지형경관 자원과 지질특성의 희소성, 대표성, 학문적 가치 및 활용가치에 중점을 두고 전문가와 협의하여 보존가치가 있고 지리적으로 접근하기 편리한 노두 8곳을 선별하였다. 선별된 8곳의 노두는 고생대의 암석과 지층, 뚜렷한 퇴적구조, 화석, 규모가 크고 전형적인 하천지형이 나타나는 곳으로 지질유산(지형 지질)의 내재적 가치와 지구과학적 이해를 도울 수 있는 대상지이다. 대상지의 지질다양성에 대한 조사를 토대로 야외 지질학습장과 지질공원 및 지질명소, 과학적 특별흥미지역 등을 개발하여 제공함으로써 지형 지질에 대한 자기주도적 학습 능력 신장과 지구과학에 대한 흥미와 이해를 증진시키는 장을 마련해 줄 수 있을 것이다. 또한 과학적 가치와 더불어 사회적, 문화적 가치를 부여하여 보전함으로써 지질유산(지형 지질)에 대한 새로운 시각이 생길 것이다.

The purpose of this study is to analyze the previous research on geological fieldwork from 2000 to 2020, examine the tasks that have been focused on, and suggest directions and implications for future geological fieldwork research. The data was conducted for the thesis searched on ScienceON and RISS in relation to geological fieldwork and journals listed in the Korean Citation Index(KCI), and the study title was analyzed using the semantic network analysis. For analysis, the data that had been pre-processed was visualized as a network by semantic network analysis, and frequency and centrality were analyzed. The centrality analysis was based on degree centrality and eigenvector centrality, and all analyzes were performed by dividing the entire study period into four periods: 2000-2005, 2006-2010, 2011-2015, and 2016-2020. As a result, research on geological fieldwork focused more on the development of geological field courses, and in particular, jeju island was actively discussed as a learning site. Also, the study was conducted on students rather than teachers, and among them, high school students showed high frequency and centrality. In addition, it can be seen that studies on the educational effect of geological fieldwork were discussed, either in connection with programs such as STEAM, free-semester program, or indirect geological fieldwork methods such as web, flash panorama, and 3D. This study is meaningful in that it suggests the direction of future research by looking back on the research on geological fieldwork that has been done so far.

The concepts of geotourism and geoparks have emerged due to the paradigm shift in tourism and the increased recognition of geosites and geoheritage as legacies that must be protected and preserved. The number of geoparks designated by UNESCO and national governments is increasing globally. The purpose of this paper is to propose directions for enhancing Jeju Geopark to perform as a geological educational venue. This study reviewed the present conditions of the education and communication, the media, and the facilities of the geopark with respect to the required conditions to be effective for geological education. Data surveys, field surveys, visitor questionnaires, and interviews were conducted to examine the educational and guidance system of the geopark, the physical space configuration, and the operation and management methods. The research process is as follows. First, the study analyzed the status of the education and communication in Jeju Geopark, according to the criteria of the UNESCO GGN, using data acquired from the survey. Second, the study analyzed and evaluated the educational and communication facilities, and media, focusing on four aspects of the geopark: the geo-trail, spatial composition and layout, communicational and educational facilities, and the system and design of signboards. Third, the study assessed the perception and satisfaction of visitors to the geopark. Fourth, the study summarized the potential and limitations of the Jeju Geopark through in-depth interviews. The four analyses showed that enhancements in the exploration environment, communication, media, and operation and management system are all necessary for effective geological education. Based on these results, this study suggests directions for enhancing the geopark in the four following aspects. Management and maintenance must be improved to meet UNESCO criteria, while the improvements in the visiting environment quality, the supplementing of communication and facilities, and enhancements in the organization and system of operation and management also must be taken on.

In geoscience and engineering the geological characteristics of sediment strata is crucial and possible if reliable borehole logging and seismic data are available. To investigate the characteristics of the shallow strata in the Korea Strait, laboratory sonic logs were obtained from deep borehole data and seismic section. In this study, we integrated and analyzed the sonic log data obtained from the drilling core (down to a depth of 200 m below the seabed) and multichannel seismic section. The correlation value was increased from 15% to 45% through time-depth conversion. An initial model of P-wave impedance was set, and the results were compared by performing model-based, band-limited, and sparse-spike inversions. The derived P-impedance distributions exhibited differences between sediment-dominant and unconsolidated layers. The P-impedance inversion process can be used as a framework for an integrated analysis of additional core logs and seismic data in the future. Furthermore, the derived P-impedance can be used to detect shallow gas-saturated regions or faults in the shallow sediment. As domestic deep drilling is being performed continuously for identifying the characteristics of carbon dioxide storage candidates and evaluating resources, the applicability of the integrated inversion will increase in the future.
