Recent reports studied that injuries or deaths frequently occurred in consumer product accidents by product defects. Broadly speaking, product liability is liability which is imposed upon a manufacturer or other seller for personal injury, death, property damage and/or commercial loss arising with respect to a product or service provided by it. In this study, we want to search a method of prevention against appling PL laws. The way was researching on the level of appreciation of PL law, warning messages's means and design criteria for seller or consumer of child toys. As a result, most people didn't understand PL laws. Although they read them before purchasing child toy, many consumers didn't differentiate means of "Notice", "Warning", and "Danger" in warning messages. In addition, they considered important factors in warning messages as notice warning, safety mark(UL, etc), age recommendation and color in order. This study will be effective to search a method of prevention against PL laws.

It is desirable that the management of human resources, as a strategy for the competition, should be the necessity for the hotel industries to survive in the rapid change and continuous development In other words, the management of enterprise provides the foundation to form human relationship, just as the hospitality industry operates with human relationship. Here by, all the problems out hotels have faced are that our hotels should look for a new human resources. The control of human resources in hotels means that if does not only satisfy hotels, employees, and guests but improves the personal ability. also it is important for the method of hotel operation as a management. Therefor, hotel managers have to get a good human resources, at the same time, improve the potential ability from them in order to get development for industries and a person. This study in the effective project for the human resources in hotels is relation to the organization of hotel sand he factor of human resources. This research if focused on the property of classification each factor in the control of human resources. according to the classification, the relationship and an effect are commonly made in groups of properties and are named respectively.

There is an advantage that RFID system is better than previous bar code system in storage ability and noncontact property. But, everyone can easily receive the transmitting information by using RF signal. So, there is a problem that system security and personal privacy are threatened. In this paper, I propose RFID system that is secure against attacks like eavesdropping, replay, spoofing and location tracking and can efficiently provide mutual authentication services between reader and tag. The proposed RFID system can be used in various sections of ubiquitous computing environment.

Press brake is used as bending and forming sheet metal in vehicle and many kind of industry. This paper deals with development of NC press brake based on high precision positioning device and software, which can be operated on personal computer. In this system, positioning device is used for controlling bending angle and operated by the developed software, which is database from material property, width and thickness of material. This study will make distribution in development of computer aided press brake.

GSM(Global System for Mobile Communications) is a Pan-European digital cellular mobile system supporting widespread roaming and personal communication services in a worldwide wireless communication network. In suite of providing security capability, however, there are some problems like user authentication in GSM. In this paper, we propose the enhanced authentication mechanism to verify strongly each network entity to so]ye user authentication problem and support anonymity for user privacy.

Cloud computing has brought changes to the IT environment. Due to the spread of LTE, users of cloud services are growing more. This which provides IT resources to meet the needs of users of cloud services are noted as a core industry. But it is not activated because of the security of personal data and the safety of the service. In order to solve this, intrusion detection system is constructed as follows. This protects individual data safely which exists in the cloud and also protects information exhaustively from malicious attack. The cause of most attack risk which exists to cloud computing can find in distributed environment. In this study, we analyzed about necessary property of network-based intrusion detection system that process and analyze large amount of data which occur in cloud computing environment. Also, we studied functions which detect and correspond attack occurred in interior of virtualization.

Product liability is the law of the manufacturer's responsibilities for the consumers' personal injuries or the losses of property resulted from defective products. In today's many countries, the product liability law are being enacted because of the safety of product use and the protection of consumer's right. In korea, the product liability is going to enforce on July 1, 2002. Though the construction of product liability response system is urgent situation, domestic manufacture company's PL response system is not nearly prepared in present. Consequently, the purpose of this study is to discuss the Quality Management's importance and the PL countermeasures by presenting the difference of PL response system construction degree by the Quality Management Maturity degree

It is assumed that employees' ethical judgements and attitudes in handling personal and organizational information differ, depending upon their hierarchical ranks in organizations and types of information. Therefore we investigated how differently employees at different ranks judge hypothetical behaviors(or situations); their manner of handling various types of information in their daily activities in business organizations. Sixteen hypotheses based on combinations of 3 ethical areas and 5 information types were developed and tested. We found that three management ranks have shown significantly different ethical attitude about i)the accessibility to strategic planning and managerial information and ii)the property of managerial, operational and informal information. This research can help organizations to design better education programs and ethical codes to guide employees who process sensitive information.
