Since the emerging period in !be Greek era, geography bas been defined as an empirical science in which travel and field trip bas been regarded as its major method for acquiring geographical knowledge or discovering geographical facts on the earth surface. In the contemporary geography, however, this kind of empiricism has been reduced to logical positivism which pursues rigid geographical laws, while diverse implications for empiricism (especially, that implied in the mythic imagination) have been ignored. On the other hand, recently a lot of books on trip for exploring regional cultural environments from the local to the global level have been poured out from outside of geography, and place-marketing has gained some attraction as a new method or strategy for regional development This paper is to consider diverse methodological implications of experience through geographical exploration especially hath from the standpoint of empirical geography and of humanistic geography, and the look on methodologically importance and limitations of place-marketing for regional development In conclusions, it is emphasized that those methodologies should be put together for a genuine exploration of regional cultural environment, and that place-marketing should be understood as a movement for rediscovering regional identity.

ICTs(Information and Communication Technologies) have changed the ways of social activities and communications, and in the process, online and offline spaces have been thought of as binary spaces in which online spaces substitute and erode offline spaces. The aim of this study is to explore how urban space where local social activities and communications are performed is constructed in terms of timespace through the intersection of online and offline communications and how the urban space is 'remediated' through online spaces. For this, the study looks at the case of a workshop on 'locality education' held at the Yeungnam University Museum in January 2013. Criticizing the dichotomist viewpoint that increasing in communications through online spaces results in the expansion of 'absent presence' or 'placelessness' in offline spaces, the study argues that online spaces remediating offline spaces are spaces not transcending the timespace constraints of the offline spaces but rather reflecting the spatial, temporal, material, social, cultural environments of urban space and place.

MnAPSO-34 and Mn-impregnated SAPO-34(Mn-SAPO-34) sample were prepared with various manganese contents and studied by electron spin resonance(ESR) and electron spin echo modulation(ESEM). Electron spin echo modulation analysis of 0.07mo1 ％ Mn(relative to p) in MnAPSO-34 with adsorbed D$_{2}$O shows two deuteriums at 0.26 nm and two at 0.36 nm from Mn. This suggests that two waters hydrate an MnO$_{4}$ configuration with a D-O bond orientation for the waters as expect for a negatively charged site at low manganese content (0.1 mol％), the ESR spectra of MnAPSO-34 and MnH-SAPO-34 exhibit the same parameters(g 2.01 and A 89 G), but the spectra obtained from MnAPSO-34 samples are better resolved. The decomposition temperature of as-synthesized MnAPSO-34 were in the range of 200-600 $^{\circ}C$ of the morpholine which is 12 $^{\circ}C$ higher than that in as-synthesized MnH-SAPO-34. Infrared spectra showed that the position of a band at 3450 $cm^{-1}$ / shifted about 15 $cm^{-1}$ / toward higher energy in MnAPSO-34 versus MnH-SAPO-34. The modulation depth of the two-pulse ESE of MnAPSO-34 with adsorbed D$_{2}$O is deeper than that of MnH-SAPO-34 with adsorbed D$_{2}$O. Three-pulse ESEM of MnAPSO-34 and MnH-SAPO-34 with adsorbed deuterium oxide shows that the local environments of manganese in the hydrated samples are different, suggesting that Mn(II) is framework substituted in MnAPSO-34 since it obviously occupies an extraframework position in MnH-SAPO-34.

Switch-based network is suitable for the environment of demanding high performance network. Traditional shared-medium Local Area Networks(LANs) do not provide sufficient throughput and latency. Specially, communication performance is more important with multimedia application. In these environments, switch-based network results in high performance. A kind of switch-based network provides higher bandwidth and low latency. Thus high-speed switch is essential to build switch-based LANs. An effective switch design is the most important factor of the switch-based network performance, and is required for the multicast message processing. In the previous cut-through switching technique, switch element reconfiguration has the capability of multicasting and deadlock-free. However, it has problems of low throughput as well as large scale of switch. Therfore, effective multicating can be implemented by using divided hardware unicast and multicast. The objective of this thesis is to suggest switch configuration with these features.

In the print world libraries have served as the archival repository for journals that they owned. In the age of digital information, however, with the licensing of electronic journals libraries purchase access to journal contents rather than paying for ownership. Libraries note the potential benefits of electronic journals, but also quake at the thought of inaccessible electronic journal contents caused by lack of preservation, changing technology, or publisher requirements. It is real that libraries have not yet stepped in to create archives of the electronic journals they are purchasing. In the digital environments, publishers, libraries, and other information providers are not the independent units that we used to be. It will take us all working together to solve the problem of preserving access to electronic journals. Thus, it is reasonable that a national library would be charge of making a comprehensive archiving policy on electronic journals, and that cooperative agreements of local libraries can help divide responsibility for different subject areas or materials.

The development of urbanization in the twentieth century according to the rampant growth of industrialization not only brought about the improvement of life-quality but also induced us to reconsider the contemporary issues such as crisis of echo system which made us aware of the values and significance of the system and sustainable environments. As sustainability has been recognized as the holistic concept, it has been highlighted as one of the core concepts in the studies with the present ecological perspective. Particularly, as the plan of urbanization in Korea which had been based on the deconstruction has been converted into the regeneration, economic and cultural regeneration is also demanded for the future plan besides material regeneration. This study aims to scrutinize various attributes of socially sustainable designs in Yerba Buena Garden of San Francisco, USA which has been globally well known as a successful example of urban regeneration. By way of visit-and-observation of the place, the research for the study was conducted during the month of December, 2007. Three researchers visited Yerba Buena Garden to observe and take photographs and to obtain relevant data and public documents in local public library. Socially sustainable design was measured on the basis of such principles; social facilitation, permeability and accessibility, safely and emotional stability, softness and feminism, and child care convenience. Relevant data were systematically organized to support and prove the above principles. The result of the study is expected to effectively be utilized for Korean environment plan and design as a benchmarking guidelines against the crisis of degeneration and the aging society with the lowest birthrates in the world.

In this paper, we discuss a new architecture of future Internet for mobile-oriented environments, named Mobile-Oriented Future Internet (MOFI). The MOFI architecture is designed with Host Identifier and Local Locator (HILL) for identifier and locator separation. Based on the HILL separation architecture, we propose a Dynamic and Distributed Mapping System (DDMS) for identifier-locator mapping control. In DDMS, the mapping control function is distributed onto each access router in the domain, which is different from the centralized approach using a central anchor. For validation of the proposed MOFI-DDMS architecture, we implemented the data delivery and mapping control functions using Linux platform. From the testbed experimental results, we see that the DDMS architecture can give better performance than the existing Proxy Mobile IP (PMIP) protocol in terms of data transmission throughput.

Public libraries have been well adapted for the changes in lifestyle and socio-cultural environments brought by the rapid advancement of information technology, the development of mass communities, and the increase in leisure activities. Government and local communities demand public libraries to take in charge of providing lifelong education for the Public. Many Public libraries have worked as a center for life-long education, while carrying out various functions and services in close relation with the life of community members. Public libraries are in a very poor condition, lacking the facilities, professional workforce, budgets, and so on, which are sufficient to strengthen their role as a center for life-long education. In this study, the roles of public libraries in developing life-long education are examined as follows : First, the concepts and directions of life-long education are discussed : second, the roles of public libraries in facilitating life-long education are examined and third, the categories of life-long education programs of public libraries are suggested.

This study aimed to identify orientations for the development of the community by establishing desirable aesthetical environments and reorganizing the residents' communal way of life through the implementation of village art projects. To investigate how the implementation of village art projects influence community and communication, the author analyzed changes in walls made by the implementation of actual projects in Anhyeon Village in Gochang, Dongpirang in Tongyeong, and Byeolbyeol Village in Yeongcheon. The community was analyzed from the view points of locality, communal ties, and communication. The results showed that Anhyeon Village in Gochang expressed its locality with chrysanthemum, poems and local figures. Similar walls were built across the village to strengthen ties among the residents, and portraits used as doorplates represented communication among them. Various paintings of seas, flowers, and poems were seen in Dongpirang in Tongyeong, which were thought to be representations of its locality and the friendliness of hometown in the less favoured area. Wall paintings played pivotal roles in this village to impart to the residents essentials that should be kept to eliminate inner walls in their minds and ensure open communications. In Byeolbyeol Village in Yeongcheon, locality was presented with common farm village landscapes in various materials, patterns and formativeness. Village-wide reinforcement contributed to strengthening ties in the community rather than forming boundaries against outside worlds. Cultural and artistic elements structured mental walls that made people not aware of the presence of physical walls.

This paper proposes a new protocol to enhance the routing performance and applies our proposal to AODV (Ad hoc On-demand Distance Vector routing) protocol, which is a typical on-demand routing protocol in MANET. In general, when a route repair procedure is performed due to the transfer or failure of a node, the source node re-initiate a route discovery procedure in most routing protocols of MANET. This causes to increase the control traffic overhead largely and degrade the routing performance. The main idea of our study is to provide a methodology that can minimize the control traffic overhead and enhance the performance by initiating a route repair procedure at destination node and utilizing the previous routing information maximumly. To evaluate the performance of the our mechanism, we have performed a series of simulations. The simulations include comparisons with AODV and AODV with local repair. The simulations have been executed under simulation environments taking into account mobility speed and network site. The simulation results show that our proposal overall outperforms the existing protocols.
