Despite manufacturers' effort to provide safe and reliable products, a number of product-related accidents occur all over the world resulting in much damage to property, personal injury and even loss of life. Considerable evidence indicates that some accidents arise from user negligence, but most are due to the design, manufacture, and distribution of unreasonably dangerous products when compared to their use. As a result, a tremendous number of product liability lawsuits have been filed, many times causing huge amount of financial damages to manufacturers. Furthermore, with increasing government regulation and growing power of consumer lobbies, manufacturers might be more exposed to product liability claims in the future than now. The objectives of this study are twofold: to provide a framework of future research on product liability and safety and to introduce a product safety policy. To accomplish these objectives, previous studies on product liability and safety were reviewed thoroughly. The product safety policy consists of two parts: (1) an engineering design strategy for reducing product-related risks and (2) a management program for a product liability loss prevention plan. The policy is essential to preventing manufacturers' liability exposure as well as designing a safer product.

The number of high-rise buildings already constructed and/or being constructed is getting increased both domestically and internationally, for example, Lotte World 2 in Seoul and Taipei 101 in Taiwan, respectively. Maintenances of those skyscrapers, especially in fire-fighting safety, would be different from those of conventional buildings and are one of keen issues. In this study, the features of risks in aspects of fire-fighting safety for the buildings are investigated and the corresponding fire safety measures are proposed to prevent the disasters and to minimize the personal and property damages from it. The proposals include the specialization in self fire-fighting managements, the realization of self fire-fighting maintenance, the establishment of the integrated fire-fighting system, and the correction of inconsistencies in related laws on fire-fighting safety.

The development of human civilization has been accompanied by a corresponding development of storage facilities. In particular, the storage of residential spaces not only performs the storage management function for personal property but also is considered an important prerequisite for a comfortable life. While examining the history of the transformation of built-in furniture, this study emphasizes the social and cultural implications of Korean residences. Therefore, We attempt to uncover the Korean characteristics that can be discovered in the transformation of storage furniture according to the changes that occurred in Korean residential forms following the modern era and to question the problematic issues of the built-in furniture in Korea.

The first product liability laws went into effect in Korea in July 2002. A person who suffers personal injury or damage to property due to defects in a product may sue both the manufacturer and the seller of the product under the principles of Korea tort law. This paper presents an integrated methodology which is called the QDRD(Quality deployment and reliability deployment) for hazards analysis in new product designs. QDRD applies QFD, FMEA and FTA to identify the hazards component, hazardous situations and hazardous events which could lead to an accident. An example is provided to demonstrate hazards analysis on a product using the QDRD method.

Two important requirements in broadcast encryption schemes are traitor traceability and revocability. In this paper, we propose a new type of a traitor tracing scheme that can revoke an unlimited number of traitors\` personal keys. Additionally, we propose an efficient and simple method to provide self-enforcement property. We also describe a variant of our scheme of which encryption algorithm is secure against adaptive chosen ciphertext attacks.

Trade rules in service and digital sectors mainly focus on reducing regulatory uncertainties by improving transparency and minimizing unnecessary requirements. Recognizing the importance of digital trade rules and trade in information and communication technology (ICT) sectors, governments worldwide have rapidly adopted and expanded rules on free flow of data, personal data protection, electronic authentication, and cybersecurity. On the other hand, advances in technology have led governments to face multiple threats related to cybersecurity, intellectual property (including that related to source code and algorithms), and unauthorized access to proprietary information of their suppliers. This study presents digital trade rules related to digital security emphasizing cybersecurity, source code, and ICT products that use cryptography in different trade agreements. Additionally, it introduces various approaches that major countries are taking to both address digital security issues and seek balance between security enhancement and trade liberalization.

Lack of client involvement in construction of public projects has been identified as the main cause of many operational problems. Clients need to perform their roles and responsibilities effectively and efficiently at the right time and through the use of correct methods in order to have the optimum involvement required during all the construction project phases, namely, the planning, design, construction, handover, and operation and maintenance phase. This paper investigates the influence of clients' individual factors on their involvement in construction project delivery. A questionnaire survey was distributed to various government agencies of the Kingdom of Saudi Arabia (KSA). Explanatory Factory Analysis was performed to group nineteen individual factors. The factor analysis result suggests that the individual factors that can involve clients' involvement in construction projects can be grouped into five, which are: adequacy of knowledge and experience for decision making in the early stage of design; ability to communicate clearly; job satisfaction; personal skills; and expertise in design and construction.

N-acyl taurates are known as environmental-friendly and non-irritating to skin. In this study, the physicochemical properties of N-acyl taurates, which are amide-type anionic surfactants, were measured and also compared with sulfate-type anionic surfactants that show low biodegradability and are highly irritating to skin. The possibility of replacing the currently existing sulfate-type surfactants by N-acyl taurates was examined. Based on the experimental results, shampoos were formulated with these anionic surfactants and their stability and properties were measured. The possibility of application of amide-type surfactants to personal care cleaner was evaluated. Experimental results show that N-acyl taurates have various favorable aspects in making personal care cleanser: high viscosity, low surface tension, and low CMC values. These properties of N-acyl taurates generate nano-scale particles in emulsion, which is stable due to its high viscosity. This emulsion also has good cleaning ability with small amount of usage due to easy penetration into contaminants. Shampoo with N-methyl oleyl taurate showed high yield point and constant viscosity, and formed stable emulsion with nano- scale uniform particles. These results suggest that N-acyl taurates play an important role in making stable Interior structure in shampoo, and which improves the storage property.
