Conventions play important roles as tools for effective marketing. It will be able to understand the changes of particular industry's market, develop a new market and potential clients, and get a chance such as strategic network constructing. To support effective viewing of visitors, conventions have introduced a variety of ubiquitous computing technologies. This study introduces a case of applying the Utility Tag-based convention service system at the Cosmetics & Beauty Expo, Osong Korea 2013. The Utility Tag-based convention service system is constructed total three systems: (1) NFC Tag Management System; allowing effective access and management of NFC tags in various locations and objects, (2) Information Provide System; allowing participating vendors to manage information they want to provide information to visitors, and (3) Utility Tags; providing a variety of service to visitors for effective viewing in exhibition/convention space. This study first explores literature review and applying case related to ubiquitous computing in this field and introduces Applying an Utility Tag-based convention service system. In addition, we analyze visitors' behaviors and association rules by take advantage of collected touch data, present various possible for applications of the Utility Tag-based convention service system.

We are entering into a era of enterprise computing that is characterized by an emphasis on broadband convergence, knowledge s haring, and calm services. Some people refer to this as the "ubiquitous" computing because its focus is on a high degree of connectivity between a company and its customers, suppliers, and channel partners. Ubiquitous computing technology, "RF" stands for "radio frequency"; the "ID" means "identifer". The tag itself of a computer chip and an antenna. The shortest metaphor is that RFID is like a bar-code but is read with an electromagnetic field rather than by a laser beam. Much has already been written about the use of RFID. But there is no has written about the use of RFID in the convention industry. Therefore this study have specific objectives as follows. 1. To give details on the use of RFID in convention. 2. To introduces the key concepts behind RFID technology. 3. To identify advantage & disadvantage of RFID technology using a BEXCO CASE study. 4. To study on ubiquitous convention using RFID and effective operation methods such as entrance identification system, session management, machine management, CRM management, visitor management, and contents management. This results provide into the current status of ubiquitous computing technology in convention industries. Specific advantages by using ubiquitous computing technology(RFID) are one-stop differentiate service, wireless internet service, use of visitor management system, entrance by tag, and U-logistics. On other side, disadvantages are security, stabilization of RFID system, higher price of RFID tag, and commercial scale. Convention by using of RFID technology is currently at an early stage. Convention company as BEXCO need to have the capabilities to adapt, to customize, to commercialize, and to modify technology to suit our circumstances.

RFID, Radio Frequency Identification, is a technology of automated identification replacing bar-code. RFID technology has advantages that it recognizes fast and it is strong to contamination using wireless communication. However, there are difficult problems that should be solved for popularization of RFID. Among of these, tag anti-collision problem is dealed in this paper. It affected the performance of RFID system directly. This paper analyzes conventional algorithms and proposes new algorithms of tag anti-collision. The algorithm proposed was composed of appropriate properties to each phase of distribution and recognition as hybrid between ALOHA-based algorithm and QT-based algorithm. At phase of distribution, the number of tags recognizing at a frame was reduced using ALOHA-based algorithm. It addressed the delay problem because of deep depth of tree. At phase of recognition, it solved ALOHA-based chronic problem that couldn't recognize all the tags sometimes. Moreover, QTR algorithm that recognize by reversed tag IDs was adopted for the performance. The FQTR algorithm proposed in this paper showed brilliant performance as compared with convention algorithms by simulation.

To estimate the movement of Pacific cod Gadus macrocephalus in the Korean Southeast Sea, three type tags were used. A total of 97 Pacific cod were tagged and released with either archival tags or conventional tags. Of these releases, commercial fishermen recovered thirteen conventional tags, and five of seven pop-up tags transmitted data to Argos satellites. Pacific cod began to move towards East Sea after release, and they spent most of their time at depths of 100 to 300m, water temperatures of 0.8 to $14.0^{\circ}C$. However, geographical ranges of their movement limited to area around the southern East Sea. Pacific cod attached conventional tag were recaptured near the release site(Jinhae Bay: main spawning ground) about one or two year after release. Data obtained from tagging investigations suggest that they migrated annually from spawning ground to habtat of the Korean Southeast Sea.

In case of C-410/11, Pedro Espada $S\acute{a}nchez$ and Others v Iberia $L\acute{i}neas$ $A\acute{e}reas$ de $Espa\tilde{n}a$ SA., ECLI:EU:C:2012:747, the passengers of a flight between Barcelona and Paris, whose baggage had been lost, lodged a claim before a Spanish court, asking for compensation. More specifically, the claimants were a family of four (two adults and two children), and had stored all their personal items in two suitcases, which had been checked in and tagged but never returned to the passengers in question. The four claimants relied on the Montreal Convention, ratified by the EU, which provides that each passenger can claim up to 1,000 SDRs in compensation (i.e. ${\euro}1,100$) in case his or her baggage is lost; thus, they sought to recover ${\euro}4,400$ (4,000 SDRs, i.e. 1,000 SDRs x4). The preliminary reference issue raised by the Spanish court to the CJEU regarded the $Montr\acute{e}al$ Convention's correct interpretation; in particular, it asked whether compensation should be available only to passengers whose lost baggage had been checked in "in their own name" or whether it is also available to passengers whose personal items had been stored in the (lost) baggage of a different passenger. The CJEU held that compensation had to be granted to all passengers whose items had been lost, regardless of whether these had been stored in baggage checked in "in their own name." In fact, it maintained that the real aim of the $Montr\acute{e}al$ convention is to provide passenger-consumers with protection for the loss of their personal belongings, so the circumstance of where these were being carried is not relevant. Nevertheless, the CJEU clarified that it is for national courts to assess the evidence regarding the actual loss of an item stored in another passenger's baggage, and maintained that the fact that a group of people were travelling together as a family is a factor that may be taken into account.
