This paper proposes a framework for personal location based services with personal life content, for example diaries, schedules and to-do lists. A lot of Internet users are recording their personal experiences and knowledge as text and other digital media on the network. Our proposed tool provides users with an environment to store personal records with related place attributes, and to retrieve these personal records at the right place. There are two applications on this tool, a place-enhanced blog and a LBS client on a mobile phone. The place enhanced blog provides users with blog interfaces for inputting place information. The place rem inder is a browser for spatial data on the place enhanced blog. Users can generate place information by writing personal records on their blog. Furthermore, using the LBS client, other users can retrieve personal records at the appropriate spots.

The purpose of this paper is to examine the significances of choosing the place of arbitration, the principles of fixing the place, which the major international arbitration institutions(including the ICC, LCIA, AAA, CIETAC and so on) have in their arbitration rules, and the methods of drafting the place of arbitration in arbitration agreements. When the contract parties have agreed on the place of the arbitration, the institutions have no role regarding the selection of the place of arbitration. But the parties have not agreed on the place of arbitration, it is fixed by the rules of selected institution, by considering the lists of criteria including local laws, N.Y. Convention, neutrality, convenience and so on. This author suggested four alternatives on how to designate the place of arbitration, and advantages and disadvantages of each one: the place of claimant, the place of respondent, the place agreed on in advance in Bilateral Agreement between two Arbitration Institutions established in two countries or the third country. In conclusion, the decision of all elements in the international contract is greatly influenced by the power of negotiation, and the place of arbitration in arbitration agreement has a lot of influential significances on both parties when resolving the disputes. So it is advisable for the parties to fix the place according to the global standard(the place of respondent), the arbitration rules of major international arbitration institutes and the result of the negotiation between parties.

As collaborative works have been spread over the internet, the need for information systems providing virtual workspaces has grown rapidly. Through virtual workspaces, the members participating in those collaborative works share and exchange their information effectively. It is desirable that these systems can be extended according to various requests of users, providing reliable services. In this paper, we describe a group of components for supporting collaboration and the iPlace (internet workPlace) system developed with those components. The iPlace system provides effective sharing and reusing of information among the members of collaborative groups through personal workspaces-the private spaces on the Web for each user and shared workspaces-the shared spaces for each of those groups. In addition, implemented with EJB technology, it provides highly scalable and reliable services.

Genome research has become very popular in most nations. In order to enhance the efficiency of collaboration among genome research groups, ways to store and share data, communicate with each other, be guided through right research strategies, and to easily use well-established databases. In addition, since techniques and softwares for genome research groups are well established, a similar research road map could commonly be applied. In this study, we developed a web-based work place for effective genome research, named 'BioPlace.' From the beginning of writing a proposal, research members can work on the same environment with convenient aid to share files or data. BioPlace provides various ways of collaboration methods among genome researchers. The BioPlace system supports two types of workplaces, namely 'Personal Workspace' and 'Team Workspace.' For each BioPlace user, a Persona] Workspace is provided, while a Team Workspace is provided for each group with the same purpose. In addition, BioPlace provides a 'General Research Road Map' for genome research, and several Korean user interfaces for BLAST, PDB, and Primer3. We expect that BioPlace may facilitate collaboration of genome research among the experienced scientists and help beginners in many different ways as well.

The diffusion of advanced mobile technology has introduced new types of personal information or 'location data'. These new data mean new opportunities for businesses, such as location-based services (LBS), but have resulted in new consumer anxieties regarding disclosure of personal information. This study examines the effects of the consumers' perceived control over "time-andplace" information in location-aware services on their perceived privacy risk. A total of 270 respondents participated in this study. Conditions of perceived privacy control were operationalized over time-and-place information, in a $2{\times}2$ factorial design. Results indicate that the perceived control over time-and-place personal information is a significant predictor of perceived risk, and control assurances over time-and-place information enhances the perception of control, thus alleviating the perceived risk. In addition, the effect is much more significant when time and place were combined.

The purpose of this study is to verify effects between the place attachment and the place value in public libraries; and also to identify whether frequency and purpose of usage, length of residence, and website use play a moderating role in the influential relationship between users' place attachment and the perception of place value for public libraries. Users' place dependence affected the library's value positively(+) due to moderating effect of usage frequency of the library and the users' length of residence. In order to estimate the moderating effect by purpose of use, the groups were divided by purpose of library use and the relationship between place attachment and place value by groups were analyzed. However, website usage bore no effect on users' place attachment or perception of place value to their local library. This study showed that place attachment as an affective indicator on users is very useful variable to explain the value of libraries as a social and cultural place.

Inspired by the multi-scale nature of hippocampal place cells, a biologically inspired model based on a multi-scale spatial representation for goal-directed navigation is proposed in order to achieve robotic spatial cognition and autonomous navigation. First, a map of the place cells is constructed in different scales, which is used for encoding the spatial environment. Then, the firing rate of the place cells in each layer is calculated by the Gaussian function as the input of the Q-learning process. The robot decides on its next direction for movement through several candidate actions according to the rules of action selection. After several training trials, the robot can accumulate experiential knowledge and thus learn an appropriate navigation policy to find its goal. The results in simulation show that, in contrast to the other two methods(G-Q, S-Q), the multi-scale model presented in this paper is not only in line with the multi-scale nature of place cells, but also has a faster learning potential to find the optimized path to the goal. Additionally, this method also has a good ability to complete the goal-directed navigation task in large space and in the environments with obstacles.

The development of LBS(location-based services) due to the widespread mobile environment highlights the importance of POI(point of interest) information. The accurate and up-to-date POI has to be ensured to reflect the information of rapidly changing places. For the efficient construction of POI, here we propose the novel construction system for t he place information. This system is based on crowd-sourcing in which a great number of users participate. In addition, we utilize the graph data model to build the new concept of the place information covering the wide areas extending from the specific point. Moreover, the implementation of the new system applying the graph data model and crowd-sourcing is realized in this paper. That is, this study suggests the whole new concept of the place information and shows the clustering and the renewal of the place information through crowd-sourcing.
