도로시설은 교통을 위한 가장 기본적인 인프라 시설로, 원활한 교통흐름을 위해 다양한 정보가 노면에 표시되어 있다. 이러한 정보는 도로를 유지 관리하는 과정에서 지속적으로 제거되고 다시 표시하게 된다. 노면표시를 제거하는데 있어서 기존의 방법은 토치와 그라인더를 이용한 반복 작업으로 위험성과 함께 작업자가 운행 중인 차량에 직접 노출되는 문제점을 갖고 있었다. 또한 노면표시 중 일부인 차선을 효과적으로 제거하기 위한 개선방안으로 자동화 장비의 도입과 워터젯을 이용한 차선제거 장비가 개발되어 활용되고 있으나 몇 가지 문제점을 갖고 있다. 이에 본 연구는 친환경 세척기술의 하나인 드라이아이스 블래스터 장비 도입을 통하여 자동화 차선제거 장비개발의 가능성을 검토하고자 하였다. 기본 연구 수행 결과 드라이아이스 블래스터를 차선제거에 적용하는 것은 가능할 것으로 판단되며, 향후 구체적인 장비 개발을 위한 경제성 및 타당성 분석하는데 추가적인 연구가 요구될 것으로 판단된다.

과거 지리정보시스템 GIS(Geographic Information System)의 활용영역이 정부와 몇몇 공공분야에 국한돼 있었으나, 최근 모바일, CRM(Customer Relationship Management) 등 다른 영역과 결합하면서 시장이 다양해지고 있다. 21세기 GIS기술의 발전방향은 GIS응용시스템 개발 및 공간정보 서비스를 위한 제반 기술로서 웹 GIS, 3차원 GIS, 모바일 GIS, LBS 등을 들 수 있다. 본 연구에서는 기존에 사용하고 있는 지하매설물 관련 표지못의 단순 위치파악 기능에서 탈피해서 새로운 개념의 표지못(지능형 저장 메모리장치를 내장한 표지못)을 개발해서, 현장에서 지하매설물관련 정보 (설치일자, 매설 깊이, 배관 두께, 배관 재질, 관리기관, 시공자, 연락처 등)를 입력하고 DB서버에 저장해서, 필요하면 적시. 적소에서 활용할 수 있게 한다. 본 연구를 통해 무분별한 굴착기 공사 등으로 야기되는 각종 사고를 미리 방지하고, 최소화 할 수 있으며, 싱크홀 관련 대책 수립을 위한 정보제공 등. 지하매설물관리를 체계적이며, 신뢰성 있는 정보 제공이 가능하도록, 현장에서 편리하게 정보를 입력할 방안을 제시함으로써, 지하 매설관로 사고를 절대적으로 감소시킬 수 있도록 하는 목적을 두고 연구 개발하였다.

Korean construction companies are recently facing stiff competition in free market economy, and construction projects tend to be complex and large-scale. Such an environment demands that construction companies ensure specialized subcontractors. This paper suggested a subcontractor evaluation model for selection of competent subcontractors which are equipped with operational, technical and productive ability. For designing a subcontractor model, AHP method as a group decision-marking method is applied in assigning weighting indices of evaluation elements. To verify this method, actual data collected in one of construction companies are analysed statistically.

Unlike ordinary business. it prioritizes employment over profit. So it is important to Identify the know-how of prosperous social enterprises and apply it to other cases for social enterprises to survive and be competitive. Bench-marking is not just imitation but recreation process. So it is the best management tool for distribution of successful examples.

The present study attempted to explore effective scanning and monitoring in process of risk management on agri-marine products distribution policy. The interest public's group interests clash in accordance with theme for issue on marking policy. For executing a better systematic scanning and monitoring on actual affairs of marketing, selecting information personnel, gathering and analysing information, issue and risk management and their valuation with ongoing and simultaneously. Especially, In order to explore effective scanning and monitoring as a model of risk management, the study attempted to analyze within and without environment of marketing, to analyze issue management strategy, to evaluate issue activity for likelihood and impact, risk cycle analysis, interest public's group concerned, grade of interest public's group threatened(power, legitimacy, willingness), rapport(staying close, credibility, meeting expectation). And the study make an ongoing observation progress of subjects, and the serious subjects need have made an close observation. The study suggested to establish friendly relationship between organization and interest public's group, and to regularly accomplish two-way symmetric communication.

The power demand has increased the groth of industry and improvement of life. In the past, the focus of an electric power company has been on the supply aspect of a management strategy, such as the stable provision of electric power through the construction of power equipment and least Cost planning. There has been a change of method in energy management. The balance of it seems to put forward to Demand Side Management(DSM) from Supply Side Management(SSM). Therefore, this paper is made a study for the method of energy grade of building.

Traffic conditions, in particular number of active TCP flows, change dramatically over time. The main goal of this paper is an adaptive queue management algorithm that can maintain network state of high-throughput and low-delay under changing traffic conditions In this paper, we devise Probability Adaptive RED(PARED) that combines the more effective elements of recent algorithms with a RED core. It automatically adjusts its adaptive marking function to account for changes in traffic load and to keep queue length within the desired target queue length. We simulate that PARED algorithm results in under changes in traffic load and mixed traffic load. The simulation test confirm this stability, and indicate that overall performances of PARED are substantially better than the RED and ARED algorithms.

Although unmanned aerial vehicles have been used to overcome the limited accessibility of human-based visual inspection, unresolved issues still remain. Onsite inspectors face difficulty finding previously detected damage locations and tracking their status onsite. For example, an inspector still marks the damage location on a target structure with chalk or drawings while comparing the current status of existing damages to their previous status, as documented onsite. In this study, an augmented-reality-based structural inspection system with onsite damage information marking was developed to enhance the convenience of inspectors. The developed system detects structural damage, creates a holographic marker with damage information on the actual physical damage, and displays the marker onsite via an augmented reality headset. Because inspectors can view a marker with damage information in real time on the display, they can easily identify where the previous damage has occurred and whether the size of the damage is increasing. The performance of the developed system was validated through a field test, demonstrating that the system can enhance convenience by accelerating the inspector's essential tasks such as detecting damages, measuring their size, manually recording their information, and locating previous damages.

To enhance the administrational efficiency and for university facility and space management to be public, this research suggests a competent and an objective evaluation system and index. The study will assist national and university finances to contribute towards advanced education. Furthermore, figure out the space management condition of national university by utilizing the evaluation system, and through that suggesting efficient special management method. According to the result of this study, evaluation system for university facility can be widely divided into seven categories; system preparation, members conference, propriety of space allocation, propriety of management system, space use ratio, time control of space use, imposition index of surplus use. Based on these subdivisions, the space management category contains 19 evaluation items and the marking system allows perfect score of 100 points. In result of examining space management condition using the evaluation system, space management was well enforced in research focused university group where as in education centered university group, it shows relatively low enforcement. It also illustrated that efforts of evaluation items were required in categories of imposition index of surplus use and special use ratio in order for efficient space management.
