Recently, to accelerate the Ubiquitous generation, the input interface of the mobile machinery and tools are actively being researched. In addition with the existing interfaces such as the keyboard and curser (mouse), other subdivisions including the handwriting, voice, vision, and touch are under research for new interfaces. Especially in the case of small-sized mobile machinery and tools, there is a increasing need for an efficient input interface despite the small screens. This is because, additional installment of other devices are strictly limited due to its size. Previous studies on handwriting recognition have generally been based on either two-dimensional images or algorithms which identify handwritten data inserted through vectors. Futhermore, previous studies have only focused on how to enhance the accuracy of the handwriting recognition algorithms. However, a problem arisen is that when an actual handwriting is inserted, the user must select the classification of their characters (e.g Upper or lower case English, Hangul - Korean alphabet, numbers). To solve the given problem, the current study presents a system which distinguishes different languages by analyzing the form/shape of inserted handwritten characters. The proposed technique has treated the handwritten data as sets of vector units. By analyzing the correlation and directivity of each vector units, a more efficient language distinguishing system has been made possible.

Surveying the literature of architecture since the nineteenth century, one can identify two dominant but problematic attitudes, among several, that pursue the task of defining what modern architecture is and should be. The first is the search for meaning and the second is the pursuit of form. This study, following Michel Foucault, asserts that the dual formation of meaning and form is a historical product of modernity and belies architecture's uncritical dependence on language since the nineteenth century. This study is a critique and historical analysis of this pernicious reliance, and constitutes a first step towards thinking of alternative relations between 'words and architecture' in the modern world. In reconstructing this problematic, the paper has called on Foucault's seminal The Order of Things. The study follows his construction of the Renaissance, the Classical and the Modern episteme, and in brief fashion, reconstructs the relation between language and architecture in each episteme. In analysing the Modern, the study focuses on Hegel's Lectures on Aesthetics. Hegel placed architecture in a genre hierarchy within which architecture, because of its material basis, was fundamentally limited in its ability to express the Spirit. For Hegel it was, among the arts, poetic language, and beyond art, the language of philosophy, through which the Absolute Spirit could be atttained. Much of post-nineteenth century architecture has remained within the shadow of Hegel, where architecture's materiality is perceived to be a burden, and in order to secure its relevance in modern society, architecture was deemed to pursue the role of language. As the most recent and sophisticated example of architecture's pursuit of form, the paper analyses the work of Peter Eisenman. Though Eisenman's theoretical writings are replete with post-Hegelian rhetoric, his architecture remains dependent upon the model of language, albeit a structuralist one. The paper concludes that ultimately, the pursuit of meaning and form is unable to face the crucial issue of value in modernity. While the former decides to easily what it is, the latter evades the issue itself. The second installment of this ongoing study will pursue a third possibility alluded to by Foucault, where language remains silent, pointing only to its 'ponderous' material existence.

This paper is an experimental result of investigating lateral soil movements at piled bridge abutments by using the centrifuge model facility. Three different centrifuge model experiments, changing the methods of ground improvement at bridge abutment on the soft clayey soil (no improvement, preconsolidation and plastic board drains (PBD), sand compaction pile (SCP) + PBD), were carried out to figure out which method is the most appropriate for resisting against the lateral soil movements. In the centrifuge modelling, construction process in field was reconstructed as close as possible. Displacements of abutment model, ground movement, vertical earth pressure, cone resistance after soil improvement and distribution of water content were monitored during and after centrifuge model tests. As results of centrifuge model experiments, preconsolidation method with PBD was found to be the most effective against the lateral soil movement by analyzing results about displacements of abutment model, ground movement and cone resistance. Increase of shear strength by preconsolidation method resulted in increasing the resistance against lateral soil movement effectively although SCP could mobilize the resistance against lateral soil movement. It was also found that installment with PBD beneath the backfill of bridge abutment induced effective drainage of excess pore water pressure during the consolidation by embanking at the back of the abutment and resulted in increasing the shear strength of clay soil foundation and eventually increasing the resistance of lateral soil movement against piles of bridge abutment.

Purpose: This study, which is based on the investment payback periods, aims to suggest the proper insulation level which can be adapted to the Defense Military Facility Criteria regarding the military residential condominiums. For the energy performance simulation, it is required to collect the residential data regarding the military condominiums and climatic data concerning the regions they belongs to. The estimates through energy performance simulation are the regional heating loads and the heating transmission coefficients of building components. Method: With the heating loads, the annual heating cost saving per square meters is assessed. With the heating transmission coefficients of building components, the additional insulation installment cost per square meters is evaluated. With two outcomes, one as an annual value and the other as a present value, the investment payback period is calculated. Result: In result, it could be concluded that 55~70% insulation ratio can lead a superior residental environments as well as be contributed to the national policy associated with zero-energy buildings because the estimated investment payback period is shorter than the life span of the military residental condominiums. This upshot can be used as a foundation to enactment the Defense Military Facility Criteria associated with military residential condominiums.

On-line education is activated in many knowledge domains and institutions, the effectiveness is under the question. Even though the role of e-moderator for on-line course is very important, but this role has been abandoned both by instructor and course administrator. On the other hand, open source solutions have made it possible to implement on-line for free of charge, but not many people know how to use it. This paper describes how to install open source on-line learning environment and how to administrate learning by being a good e-moderator. Moodle is selected as an implementing LMS(Learning Management System). The environment is installed and serving well for teaching two engineering education subjects: JAVA and Electrical Machines. The practical tips for installment and administration are presented with examples.

This paper explores the policy alternatives to promote efficient use of spectrums for public use and terrestrial broadcasting, which are essential to provide spectrum for mobile broadband services. To this end, recent overseas spectrum management policies are introduced and utilized to provide domestic policy alternatives. For the efficient use of spectrum for public use, policy alternatives such as detailed survey of current usage of spectrum for public use, levying the opportunity cost, installment of spectrum efficiency fund, providing incentives for the efficient use of spectrum for military use, and introduction of shared use are proposed. For the efficient use of spectrum for terrestrial broadcasting, short-term policy alternative such as change of contribution rate base of the broadcasting - telecommunications development fund is proposed. For long-term policy alternatives, change of spectrum provision from designation to allocation for the spectrum for commercial terrestrial broadcasting and introduction of administered incentive pricing to public terrestrial broadcasting are proposed.

To confirm and quantify asbestos fibers released from the asbestos-cement slate roofs due to weathering, three houses, selected based on the year of built - 60's, 70, and 80's, were investigated. All of them were located in the downtown of Seoul. Rain or snow-melt water was collected from the roof in a 3.5 liter plastic bottle. A known amount of collected water was filtered on the 37 mm membrane filter, ashed in a muffle furnace, and subsequently treated with HCl to remove organic material. The treated remaining was refiltered on a 25mm membrane filter for PLM and PCM analyses. The NIOSH 7400 method was utilized for PCM counting. In addition, SEM/EDX was used to confirm the asbestos types. The results of this study showed that chrysotile fibers were confirmed by PLM in all samples analyzed. A significant amount of asbestos fibers were found in the water samples. The ranges of asbestos fibers counted from the samples collected in the 60's, 70's, and 80's were; 10,406.3~55,575.6 f/L, 5,218.8~38,126.2 f/L, and 2,906.3~7,798.6 f/L, respectively. As anticipated, concentrations of asbestos fibers increased with time of installment of the roofing material. We conclude that weathering can be a significant factor on the release of asbestos fibers from the asbestos cement products. Since asbestos fibers released into environment can be a source of significant health hazard, countermeasures, such as replacement, removal, and encapsulation of weathered asbestos slate, should be initiated immediately.

The NASA Antarctica balloon experiment CREAM has successfully collected the data of energetic cosmic rays during flights in past years. We will present the recent analysis results of the CREAM experiment. We will also report on the launch and recovery process of the latest flight. The silicon charge detector of the CREAM has played the key role in the precision measurement of the charge constitution of energetic cosmic rays. We proposed the upgrade of the CREAM experiment with the installment of a new large silicon charge detector on top of the CREAM instrument. The charge measurement of the large silicon detector with no material in front is expected to improve the accuracy of the CREAM charge measurement drastically when combined with the measurement of the existing double layer silicon detector. We will present the fabrication of the large silicon detector and its performance in the radiation source test as well as in the beam test.

Recently, vessel hijacking by pirates has been a big issue around the world. In case of the hostages of M/V "SAMHO Jewelry" on January 20, 2011, the Korean Navy has rescued 21 seafarers by first naval operation with somalia pirates since establishment of the Navy. Also, in case of the "HANJIN Tianjin", all crews evacuated to the Citadel promptly when being attacking by pirates and were safely rescued by the navy. By the accident, Necessity of Citadel for seafarer on board ship came to the fore against pirates. Taking in account increasing pirates accident at sea, many research relating to pirates has been implementing with a view to responding to them so far. By amending the ship facility regulation in the domestic law on Jan. 2011, the installment of Citadel on board ship became mandatory for ocean going vessel serving pirates area. Hence, this paper provides new model of Citadel structure based on an Fire Dynamic simulation in order to improve personal safety in case of vessel hijacking.

The purpose of this study was to investigate and analyze the function and scale on aspect of construction planning with examples of exhibition and convention facilities constructed recently in domestic and foreign area. Also, it was to provide the result for basic data for construction planning and architecture of similar facilities constructed later. The study methodles, but they had characteristics to use the space with compound purpose for exhibition, conference, etc through installing multi-purpose hall. Finally, for effective construction planning of exhibition and convention facilities, it was required to decrease the ratio of common area gradually and derive rationalization of whole space composition by deriving complexity of function rather than planning of single purpose of each facility for exhibition and conference function. was to analyze the characteristics of construction planning for composition and scale of exhibition, conference, public use, support, maintenance functions, etc and placement composition of unit rooms by each floor on the basis of internal area of exhibition and convention facility in Korea and Japan. As the result of analyzing 10 examples(K1~J5), the placement of auditorium and multi-purpose hall was affected according to location of exhibition room and conference room in the composition of unit rooms by each floor and the installment ratio of support facility in Korean examples was higher than in Japanese examples. In case of facility scale, the Japanese examples were overall small in the whole scale relatively to Korean examp.
