Construction projects are fraught with risks from cost or other overruns to accidents along with other issues. This is true whether the relevant organization is an owner, general contractor, CM, specialty-trade contractor, or other entity. When cost issues or other issues confront arise, how should an organization proceed whether attempting to gain additional compensation in terms of cost/other damages or protecting the same against such claims if they do not appear to be warranted? Enter construction cost forensics. This presentation will focus on strategies/techniques with construction cost forensics in these areas in order to be successful. Covered techniques include those to develop and analyze claims including fundamental construction cost analysis techniques. When an unexpected event disrupts a construction project, using sound analytical methods to identify the cause and quantify the extent of the issue will be important for negotiating a fair result or for obtaining a successful outcome in arbitration or litigation. Key examples of uncovering issues via construction cost forensics will be covered in this presentation.

This paper is mainly associated with setting out an agenda for the transformation of security by creating a new framework for a security system, which can maximise its effectiveness. Noticeably, this research shows empirically that crimes are getting a major cost to organisations, which if reduced by security and investigations could reap substantial rewards to the finances of an organisation. However, the problem is that the delivery of security is frequently delegated to personnel (e.g. security guards) with limited training, inadequate education, and no real commitment to professionalism - 'sub-prime' security, finally causing security failures. Therefore, if security can be enhanced to reduce the crime cost, this will produce financial benefits to business, and consequently could produce a competitive advantage. For this, the paper basically draws upon Luke's theoretical framework for deconstructing 'power' into three dimensions. Using this three-dimensional approach, the paper further sets out a model of how security can be enhanced, utilising a new Security Risk Management (SRM) model, and how can this SRM model create competitive advantage in business. Finally, this paper ends with the six strategies needed to enhance the quality of security: refiguring as SRM, Professional Staff, Accurate Measurement, Prevention, Cultural Change, and Metrics.

Trade finance promotes export performance, and every small- and medium-sized export business has the right to use policy finance. The credit line is also stipulated by relevant laws and regulations. However, trade finance has repeatedly been misused, so these matters can lead to substantial financial loss and damage to the related financial institutions. The lack of expertise of K-SURE and the backwardness of banks represent even bigger problems in the follow-up management. The existing trade finance system should be improved in the following ways from the institutional and legal perspectives. Firstly, follow-up management of beneficiary companies should be reinforced and systematized through examining business tendencies, financial status, and other important factors. There is also a need for advancement of following up management. An effective and streamlined financing system must be established by abolishing the Korea Trade Insurance Corporation. This study presents improvements and their implications by looking into the main issues under the current trade finance system. This study is based on documentary research and practical cases.

Deep learning-based anomaly detection technology is used in various fields such as computer vision, speech recognition, and natural language processing. In particular, this technology is applied in various fields such as monitoring manufacturing equipment abnormalities, detecting financial fraud, detecting network hacking, and detecting anomalies in medical images. However, in the field of construction and architecture, research on deep learning-based data anomaly detection technology is difficult due to the lack of digitization of domain knowledge due to late digital conversion, lack of learning data, and difficulties in collecting and processing field data in real time. This study acquires necessary data through IoT (Internet of Things) from the viewpoint of monitoring for environmental management of architectural spaces, converts them into a database, learns deep learning, and then supports anomaly patterns using AI (Artificial Infelligence) deep learning-based anomaly detection. We propose an implementation process. The results of this study suggest an effective environmental anomaly pattern detection solution architecture for environmental management of architectural spaces, proving its feasibility. The proposed method enables quick response through real-time data processing and analysis collected from IoT. In order to confirm the effectiveness of the proposed method, performance analysis is performed through prototype implementation to derive the results.

As science and technology infiltrates every aspects of modern society in terms of economic and social growth and development, funding for research and development (R&D) is growing rapidly. Republic of Korea is not an exception in this trend and the R&D funding in Korea has been grown about 10% every year, recently. However, as the scope and size of funding grows exponentially, need for monitoring and managing these R&D projects becoming more and more imminent. Though different types of project management systems were developed by a variety of agencies and departments and used in monitoring and managing, these systems were developed as standalone silo type systems. These systems are not connected to each other while the same researchers may involved in different projects across agencies and department. Also, these management systems are not linked to the banking systems in which real transactions of funding occurs, such as cost reimbursement and financial audit of each R&D accounts. Historically, a few fraud and malappropriation cases were found and indicted. However, as the number of these incidents grows along with the growth of R&D funding, a large scale integration/linking of project management systems and banking systems. Realizing the importance of systems integration among agencies as well as with the banking systems, situational requirements analyses were conducted concerning the current state of R&D management system. As a results, a Real-time Case Management System (RCMS) was proposed as a solution to current problems. In this paper, the collected systems requirements were documents with analyses of the situation, the architecture of the integrated systems with more user-friendly technological alternatives. This large scale linkage requires interface standardization as well as modularization of interfaces. Proposed systems architecture is introduced here with technical details of Jex Framework used,, followed by resulting technical and economic performance of the Realtime Cashflow Management System (RCMS).

위험분석과 내부통제평가는 조직 내 자산을 보호하기 위한 여러 보안관리 활동들 중 핵심적인 사항이다. 위험분석은 보호가 필요한 영역을 식별하는데 사용되는 활동인 반면, 내부통제평가는 현재의 내부통제시스템이 자산보호에 있어 만족할 수준인지를 확인하는데 사용되는 활동이다. 위험분석은 일반적으로 비인가된 사람으로부터의 비인가된 접근에 그 초점을 두고 있으며 인가된 사람으로부터의 잠재위협에는 상대적으로 적은 관심만을 가졌다. 부정행위에 대한 관심이 증가하는 현 상황에서는, 이들 위협들 또한 적절히 다루어져야 한다. 본 논문은 이 두 가지 활동을 비교하고 그 차이점을 논하는 것을 목적으로 한다.

The robustness of communication service should be guaranteed to validate its security of the whole service not just high performance. One kind of practical test-beds is the chinese communication service based on SIM Card and GSM. In paper, we try to experiment the possibility of SIM cards clone in various mobile communications using 2G in china, and hence discovered the security vulnerabilities such as the incoming outgoing, SMS service and additional services on the mobile phones using clone SIM cards. The experiments show that chinese communication service should be prepared the Fraud Management System against the cloning SIM card. and furthermore, regulations related to the communication service should be tuned the realistic security environments.
