This study aims to propose design directions for the eco-friendly, sustainable underground campus in terms of integrated design. For this purpose, theoretical investigation, design methodology and quality investigation, analytical case studies on the domestic and foreign underground campus, and user survey for POE(Post Occupancy Evaluation) and analysis on the recently built domestic underground campus plans were conducted. As a conclusion, design direction and improvement areas for the synthesized sustainable underground campus plan were proposed. Underground campus plan will be a great alternative for a 21st century sustainable campus if well-developed plans with organized design guidelines are established.

The importance and utilization of underground spatial is increasing due to urban concentration. And so underground spatial information is being built. Because underground spatial information is an important NSDI (National Spatial Data Infrastructure), the accuracy and performance of underground spatial exploration devices used for construction are managed separately. In accordance with the laws and regulations related to spatial information, the government is conducting performance tests for underground facilities surveying equipment. The current performance test site mainly targets metal pipelines, and there is no absolute position surveying inspection system. In this study, test bed model for performance inspection of underground space exploration equipment was presented. The test bed presented in this study can be used as a test site to supplement the limitations of the existing domestic test bed and to verify the performance of the latest equipment.

마천루를 비롯한 지하상가와 같은 거대한 건축물 내에서 일을 보는 경우가 흔해짐에 따라, 옥내위치기반 서비스에 대한 요구가 크게 증가하고 있는 실정이다. 근래에 판매되고 있는 스마트폰은 기존의 컴퓨터에 버금가는 계산 능력과 기억 용량을 가지고 있으면서 다양한 센서까지 장착되어 있기 때문에, 그리고 스마트폰은 사용자가 항상 휴대하고 다니는 소지품이기 때문에, 위치기반 서비스를 제공하는 장치로는 스마트폰이 제일 적당하다. 위치기반 서비스 구현에 필수불가결한 요소는 당연히 측위 컴포넌트이다. 본 논문은 스마트폰 센서를 이용하여 사용자의 걸음 수와 진행방향을 판정하고, 이를 바탕으로 사용자의 위치를 판정하는 안드로이드 앱을 설계한다.

본 연구에서는 부산시 용호만 해안대수층에서 전기전도도와 지하수위의 수직적인 관측을 통해, 조석에 의한 해수/담수 경계면의 변동을 산정하였다. 연구지역은 부경대학교 대연캠퍼스 기숙사 신축부지 주변 해안대수층이며, 응회질퇴적암과 안산암 및 안산암질 화산각력암 등으로 구성되어 있다. 관측공의 개발심도는 120 m, 케이싱심도는 19 m, 내경은 0.2 m, 관측공과 해안선의 이격거리는 180 m 정도이다. 전기전도도에 의해 산정된 밀도는 담수에서 997.58 $kg/m^3$, 해수에서 1020.36 $kg/m^3$ 이었다. 관측기간(2008년 8월 21일${\sim}$10월 18일) 동안 해수/담수 경계면의 변동 범위는 해수면 기준 -21.69${\sim}$-21.53 m 이었으며, 경계면의 평균 위치는 해수면 기준 -21.62 m 정도이었다. 해수/담수 경계면과 지하수위의 상관성은 매우 높게 나타났으며, 해안대수층 내 해수/담수 경계면의 변동은 조석의 일(고조, 저조) 및 보름(대조, 소조) 단위의 변동에 영향을 받고 있음이 확인되었다. 관측기간 동안 지하수위는 전반적으로 하강하는 경향을 나타내었으며, 이는 관측기간이 풍수기에서 갈수기로 전환되고 있었기 때문이다. 향후에는 지속적인 관측을 통해, 용호만 해안의 해수면 상승에 의한 내륙으로의 해수침투를 연구하고자 한다.

University campus has grown and developed along with history of human in connection with transition characteristics of city. In particular, reflecting the features in the times, the masterplan should explore its main roles today when international growth of university is pursued. In particular, center core and quad space, focusing on main components of campus such as main building, student union hall and main lecture facility, are the prototype of campus components and have been pursued to have importance in terms of shape and function as traditional campus space strategy. Recently, however, new strategy has been proposed to explore orders of campus utilizing the underground space focusing on main universities. Design of Hana Plaza of Korea University and Bekyangro of Yeonsei University, the targets of this study, actively explore this strategy. This study analyzed such strategies in terms of concept of space to obtain space, design trend of main universities at home and abroad, and viewpoint of integrated masterplan proposal. Conclusions from this study are as follows. First, concept of quad and center space found in the design of traditional campus is reinterpreted into new design aspects through development of underground space. Second, development of underground space is approached to overcome the limit of existing campus and to present the vision of universities 100 years ahead. Third, ever-changing complicated urban environment has been reflected in space configuration of campus and positioned as strategy to implement this as modern construction technique. Third, implementation of pedestrian-oriented campus has been pursued by reinforcing utilization of inclined topography of urban environment in Korea. This enables to obtain spaces for main activities of students and to implement the space where student support facilities are concentrated and activities are performed actively. Such features can be presented as conclusions of this study.

The Sunghak Campus, Dong-A University, which located at the excavated area of mountain, has been constructed year by year for about 10 years since 1978. The buildings, steep slopes, road and so on in the Campus area were damaged by heavy rainfall more than 200mm 1 day on August, 1989. The methods used for the investigation and repair methods of the damage are the preliminary investigation, the present condition survey, 50 by 50m grid survey, compasstraverse for locating outcrops, geopysical exploration, geologic survey, boring and laboratory soil testing. Based on the results of investigations, the causes of the failures have been evaluated, and the repair methods have been set up as horizontal drains, removal of the dangerous rock, retaining wall with subsurface drains, the elimination of colluvium and slope stabilization by use of precast concrete grids and so on.

Historically, college campuses have played a role of a city, and the development pattern of various forms and functions of cities was found in the growth stages of campuses as well. In this way, campuses developed in close relationships with our lives and such a characteristic can be confirmed in a number of cases in and out of the country. The strategic concept of such expansion is shown in the strategic classification through a master plan. This research examines concepts of major universities in the metropolitan area of Korea for promoting campus expansion and proposes implications through them. The results drawn from the research are as follows. Firstly, various developmental directions should be sought in aspects of planning, programming and economics for campus expansion with the complex application of such factors. Secondly, the multi-campus strategy of past localization era is changing into the concept of forming a global campus materializing itself as the planning strategy of internal campus. Thirdly, the physical barrier is being dissolved as a way to promote the relationship with local communities, and particularly, the management strategy of constructing new buildings in connection with local communities is the leading measure of materialization. Lastly, the development of underground space is actively carried out due to the limitation of ground physical space through which a role of establishing new campus order along with securing space is pursued.

본 연구에서는 해안가 암반대수층에서 전기전도도의 수직적인 변화를 관측하여 조석에 의한 해수와 담수 전이대의 특성을 파악하였다. 연구지역은 부경대학교 대연캠퍼스 주변 해안대수층이며, 응회질퇴적암과 안산암 및 안산암질 화산각력암 등이 분포한다. 연구에 이용된 지하수 관측공 (PK1공)은 부경대학교 대연캠퍼스 내 기숙사 동측에 위치하고 있다. 지하수공의 개발심도는 지표 면하 120 m, 케이싱은 지표면하 19 m까지 설치되어 있으며, 내경은 0.2 m로서 해안가에서 180 m 정도 이격되어 있다. 해안대수층 내 해수와 담수 전이대를 파악하기 위하여 관측공 내에 TLC Meter(Model 107, Solinst)를 삽입하여 전기전도도의 수직적인 변화를 지하수공 내 심도 50 m 까지 측정하였다. 전기전도도의 수직적인 관측은 썰물(low tide)일 때, 썰물에서 밀물(high tide)로 될 때 및 밀물일 때로 나누어 총 3회 수행되었다. 전체적인 전기전도도의 분포는 썰물일 때 $630{\sim}47300{\mu}S/cm$, 썰물에서 밀물로 되는 시기에는 $672{\sim}61900{\mu}S/cm$ 및 밀물일 때는 $678{\sim}67900{\mu}S/cm$로 나타났으며, 따라서 밀물일 때가 썰물일 때보다 전기전도도의 농도가 높은 것으로 나타났다. 해수와 담수 전이대의 분포는 썰물일 때 약 $20{\sim}50\;m$, 밀물일 때 약 $20{\sim}38\;m$ 정도로 나타났으며, 이는 밀물 시 해수의 침투로 인해 전이대 하부구간의 농도가 상승하였기 때문이다. 해수와 담수 전이대의 구간을 세분화하여 분석하기 위해, 담수가 우세한 전이대, 주 전이대 및 해수가 우세한 전이대 구간으로 구분하였다. 담수가 우세한 전이대는 썰물과 밀물일 때 모두 지표면하 $20.0{\sim}25.5\;m$ 구간이었으며, 주 전이대에서는 지표면하 $25.5{\sim}25.7\;m$ 정도로 나타났다. 그러나, 해수가 우세한 전이대에서는 썰물일 때 지표면하 $25.7{\sim}50.0\;m$ 구간, 밀물일 때는 지표면하 $25.7{\sim}38.0\;m$ 로서 전이대의 폭이 19 m 정도의 차이를 보였다. 본 연구를 통해 해안가 암반대수층에서 해수와 담수의 전이대는 조석에 의해 영향으로 인해, 썰물 시의 전이대가 밀물에 비해 그 폭이 더욱적음을 확인할 수 있었다.
