Due to the rapid development of IoT technology and the increase in home activities after the COVID-19 pandemic, users' demand for smart homes has increased significantly. As the size of the smart home market increases every year and the number of users increases, the importance of personal information protection and various security issues is also growing. It often grants temporary users smart home owner rights and gives them access to the system. However, this can easily allow access to third parties because the authorities granted are not properly managed. In addition, it is necessary to prevent the possibility of secondary damage using personal information collected through smart home devices and sensors. Therefore, in this paper, to prevent indiscriminate access to smart home systems without reducing user convenience, access rights are subdivided and designed according to the functions and types of smart home devices, and a token-based user access control technique using personal devices is proposed.

The purpose of this study was to evaluate accessibility condition of buildings in a college from manual wheel chair users' perspective in order to suggest improvements, and to develop 3D accessibility maps in order to assist manual wheelchair users' prior planning for the building use. In May 2020, on-site investigation was held to three buildings in Chungbuk National University. Major findings were as follows. (1) There were some building entrances that showed level difference over 2cm without proper ramp with slow slope 1/8 or less. (2) Some rooms were found to have accessibility issues to have floors with height more than 2cm, and/or to have no height-adjustable desks. (3) Although accessible restrooms were in good condition for manual wheelchair users' access and use, it is suggested to install accessible restroom for each gender in each floor for better access. Using the study results, 2-dimensional accessibility maps for each floor were developed in color and grayscale, which were further developed into 3-dimensional accessibility maps for each building.

There have been researches into digital Watermarking technology or Fingerprinting vigorously to safeguard Protective rights for knowledge and poverty for digital contents. DRM(Digital Rights Management) is not only Protective rights for knowledge and poverty, but also management and systems that are necessary to put out, circulate and use for contents. This paper proposes two kinds of ideas. One is protecting contents from illegal acts such as illegal copies when the contents are in the process of circulation. The other is the protocol that can give users convenience. Hidden Agents are used so that contents are protected from illegal copies and illegal use in the contents and cuts off those illegal acts. The Agent will be installed without any special setup. In addition, it can replace roles of Watermarking as a protection. Therefore, this paper shows the solution of illegal copies that happens frequently.

Subject matter of international trade are various. They contain not only tangible assets such as goods but also intangible assets including service, technology, and capital etc. Technology, a creation of the human intellect, is important as it is the main creative power to produce goods. It can be divided into Patent, Trademark, Know-how and so on. These Technologies are protected by the national and international laws on regulations for the Intellectual Property Rights(IPR), since technology development is needed a lot of time and effort, and the owner of the technology may have crucial benefits for creating and delivering better goods and services to users and customers. Therefore, any licensee who wants to use the technology which other person(licensor) owns, he(the licensee) and the original owner(the licensor) shall make Technology Transfer Contract. Differently from the International Sales Contract in which seller provides the proprietary rights of goods for buyer, in the case of International Transfer of Technology Contract, the licensor doesn't provide proprietary rights of technologies with the licensee, on the contrary the right of using is only allowed during the contract. The purpose of this paper is to examine the main issues in International Transfer of Technology Contract. This author focused on the main obligations of both parties, namely licensor's obligation to provide the technology and licensee's obligation to pay the royalty. As every country has different local mandatory laws about Intellectual Property Rights(IPR) and these mandatory rules and laws prevails over the contract, the related rules and laws should be examined carefully by both parties in advance. Especially the rules and laws about the competition limitation in the local country of licensee and the economic union(like the EU) should be checked before contracting. In addition, the contract has much more complicate and delicate aspects than other international business contracts, so both parties should review carefully before singing the contract.

As wireless Internet speads widely, circulation of various types of digital contents become active. Therefore, it is necesary to make a mobile-based DRM (Digatal Rights Management) system to protect digital contents from illegal reproduction and to give proper rights to contents users, In this paper, we present a mibile security system, which protects the copyright for digital contents offered throughout the mobile environment. Our security system is focused on presenting mobile-based DRM architecture. Especially, considering mobile device's decrying power, we adopted partial encryption scheme. For this, wecompared and evaluated the performant of each contents encryption scheme (the entire encryption scheme and the partial encription scheme) and proved that a proper DRM system for current wireless devices is the partial encryption system. Our mobile DRM system can be very efficient to protect contents on the wireless Internet environment.

As most of firms related with P2P services change their free services into fee-charging services, the problems of intellectual property rights are solved to satisfactory extent. Accordingly, P2P systems become more popular with the general public. In this respect, it is thought to be very important to research on the critical factors affecting usage of P2P systems. Although it is strongly expected that the characteristics of users activities in virtual communities affect the intention to re-use P2P systems, relatively few attention have been paid to this question. Therefore, this paper is to present empirical evidence to explain how the characteristics of users activities in virtual communities affect re-use intention of P2P services. The theoretical contribution of this study is that the characteristics of users activities in virtual communities is theoretically derived from the comprehensive literature review and the logical reasoning, and that the research model of the relationship between the users activities' characteristics in virtual community and the re-use intention of P2P services is proposed and empirically validated, which is expected to expand explaining power of the TAM(Technological Acceptance Model). Also, the practical implication is to provide the guideline to support the successful strategic planning for development and.operation of P2P services through the virtual communities.

Online games take place by the interactions among users and their contents change endlessly with their organic characteristics. Especially, digital images that make a great impact on game play such as characters or items form their own value beyond the establishment scope of their designer even outside of the game world. The users who pay fees for using them establish the concept of possession for the images and information designed in the games. Then, business transactions are formed among them who are in agreement with their values and their possession rights can be changed. In this way, digital images in the online games form new values by the interaction among other users or game systems. Meanwhile, the more the interaction and a sense of solidarity in the community increase, the higher their value becomes.

While the advanced trffic environment systems are developed recently, the traffic systems for transportation vulnerable are still under development and their social life are limited as well. In order to the secure their mobility rights, it had been required to set up the particular system for the traffic welfare. One of the significant items is the express bus operation for wheelchair users. Thus, the research of development and operation for express buses with wheelchair users was funded by the Korean government. Before the express bus development for wheelchair users based on the current bus model, this study set up the evaluation method for the bus rollover characteristics to ensure occupant safety using the finite element method. The partial bus model was developed corresponding to the full bus model response under rollover event and the evaluation method based on two model (full bus model and partial bus model) responses is planned to apply the model development of express bus modification for wheelchair users.

This research investigates the causes of infringements related to authors' moral rights which has most conflict among moral rights of authorship, through analysis of judicial precedents and compare whether there subsists any differences in viewpoints between judicial precedent trend and those on behind the scene of broadcast production. Copyright is divided into intellectual property and moral rights of authorship. Right to the integrity of the work is part of moral rights of authorship and produce one content and used in various media. When the edit is needed to fit the organization and advertisement time, advanced consultation from the rightful owner or written consent is needed. However, under the time pressure or ignorance of copyright, the arbitrary edits are made and content is used. This infringes the right of the integrity of the work. When we produce and use cinematographic works and other audiovisual works, there are considerable variablilies stemming from authorship, production cost and program staff. Therefore, prior conscent is needed to acquire and use the copyright in a proper manner. However, due to production-oriented environment and low understanding of the copyright protection, we usually depend on the users' work practices rhather than insufficiency of copyright laws in dealing with the infringement of right to the industry. In conclusion, we need to provide meticulous work manual and to focus on systematic eduction of professional copyright manpower.
