This paper provides a framework for information assurance within collaborative design, based on a technique we call role-based viewing. Such role-based viewing is achieved through integration of multi-resolution geometry and security models. 3D models are geometrically partitioned, and the partitioning is used to create multi-resolution mesh hierarchies. Extracting a model suitable for access rights for individual designers within a collaborative design environment Is driven by an elaborate access control mechanism.

As a matter of fact, the document which has been developed to resolve the obvious conflicts between the interests of buyer and seller is the bill of lading. The bill of lading provides the seller with some security against default by the buyer and the buyer with some assurance of performance of the seller before the buyer is required to make payment. So to speak, the B/L provides some extent protection for both seller and buyer. This is a study on the construction of Liner Bill of Lading(Code name : CONLINEBILL) adopted by BIMCO(The Baltic and International Maritime Conference) and is using a basic bill of lading in the liner ships operation. In this study, the writer makes a wider and deeper study of rights of rights and obligations of Contract Parties by means of the rules of construction, specially focusing the Carriers liability under Carriage of Goods by Sea Act 1971(COGSA 1971), Hague-Visby Rules and Korea Commercial Law.

Industrial control systems(ICS) are widely used in various industrial area and critical infrastructure. To mitigate security threats on ICS, the security assurance test for industrial control devices has been introduced and operating. The test includes testing of the security function of the device itself and testing of communication robustness. In this paper, we describe the security requirements of EDSA, Achilles, and Korea's TTA standard(security requirements for ICS). And also, we analyzed the characteristics of communication robustness test(CRT) of each certification. CRT verifies the device's operation of essential function while transmitting fuzzing and stress packets. Existing test methods are mostly focused on the embedded devices and are difficult to apply to various devices. We propose a method to test communication robustness which reflect the characteristics of control H/W, control S/W, field devices and network devices in ICS. In the future, we will apply the proposed communication robustness test to actual products and present solutions for arising issues.

In the field of environmental landscape architecture, the internet medium is used as an effective communication tool not only in the private level but also in the policy level. Recently, the active utilization of mobile web service is emphasized as the time changes, but there is not much improvement or advance in services due to lack of relevant studies. Therefore, this study is intended to provide basic data needed for improvement and advance by researching the quality of mobile web service among multichannel services provided in environmental landscape architecture related internet media. The model for measuring service quality is SERVQUAL, which was verified in the study of Choi(2015), Choi and Koo(2016), and the final valid samples are total 230. First, the subjects were analyzed as the representative media that are possible to acquire comprehensive knowledge related to environmental landscape architecture. Second, the highest importance level in each subsection was 'protection and security maintenance of customer information' followed by 'Reliability about accurate information supply'. Regarding performance level, 'Reliability about accurate information supply' and 'professional knowledge to communicate with users' are highly evaluated. Third, regarding Importance-Performance Analysis(IPA), the first priority management should is 'Tangibles', and the next are 'Responsibility' and 'Empathy'. The ones for maintenance of the status quo are 'Reliability' and 'Assurance', and there is none for effort reduction. Meanwhile, regarding the importance of each factor and difference in the quality of PC web service and mobile web service studied before, the biggest difference is in 'Tangibles', followed by 'Assurance', 'Empathy', 'Responsibility' and 'Reliability'. It is suggested that the revitalization of Landscape information science(LB1106) presented in the National Science&Technology Standard Classification System is needed. In the future, it is necessary to research the change trend on users' response through continuous evaluation of improved mobile web service.

For the matter of elevator, one of the multi-use facilities for unspecified public, the JIS has re-established and reformed to apply to the environment in South Korea for the past 20 years. In the aspect of safety assurance, it was inevitable to suggest improved measures. The government, Ministry of Public Administration and Security has secured the safety by enhancing the safety management functions in the elevator inspection standards and expanding its safety device measures. Further, the international inspection standard has been introduced, which is about unifying inspection standard system into the international standard code. In March 14th 2012, the international standard (EN) has been amended and fully announced. Escalator and passenger conveyor among lift devices have several common danger factor that cause safety accident. First, the accident caused by decreased braking power of brake. Second, the accident caused by the rate difference between handrail and tread-board. Third, the accident caused by defects of contraflow preventing device or carelessness inspection. Fourth, the accident caused by wet tread-board or wet floor of platform which makes passenger slip and fall. As the improvements to prevent and reduce these negligent accidents, the inspection list to check and methods should be subdivided and applied for each accident likelihood cause for safety management enhancement and safety assurance of existing escalator and passenger conveyors. The escalators and passenger conveyors without safety devices in existence should be obliged to modify the part of the system or install additional safety device. With making these measures obligations, it requires to improve the system to be suitable for the international inspection standard and to have measures to prevent safety accidents. It also needs to arrange improvements for skid accident of tread-board by the external environment factors such as snow and rain.

In this paper, we present an anonymous authentication and location assurance protocol for secure location-aware services over vehicular ad hoc networks (VANETs). In other to achieve our goal, we propose the notion of a location-aware signing key so as to strongly bind geographic location information to cryptographic function while providing conditional privacy preservation which is a desirable property for secure vehicular communications. Furthermore, the proposed protocol provides an efficient procedure based on hash chain technique for revocation checking to effectively alleviate communication and computational costs on vehicles in VANETs. Finally, we demonstrate comprehensive analysis to confirm the fulfillment of the security objectives, and the efficiency and effectiveness of the proposed protocol.

As communication technologies are developed and variety of services to mobile devices are provided, mobile users is rapidly increasing every year. However, mobile services running on wireless network environment are exposed to various security threats, such as illegal tampering, eavesdropping, and disguising identity. Accordingly, the secure mobile communications services to 3GPP were established that the standard for 3GPP-AKA specified authentication and key agreement. But in the standard, sequence number synchronization problem using false base station attack and privacy problem were discovered through related researches. In this paper, we propose an efficient authentication mechanism for enhanced privacy protection in the 3G network. We solve the sequence number synchronization existing 3GPP authentication scheme using timestamp and strengthen a privacy problem using secret token. In addition, the proposed scheme can improve the bandwidth consumption between serving network and home network and the problem of authentication data overhead for the serving network because it uses only one authentication vector.
