Nowaday, the local governments eager to change their transport system aiming for public transport oriented one. However, it is more important to change the land use system in the catchment areas of public transport in order to enhance its usage sustainably for the long run. This research aims to seek maximal spatial extent of the catchment areas of the Seoul Metropolitan Subway in consideration of its urban spatial structure in order to accommodate the potential users living around the subway stations. For this task the empirical data of the household travel survey for the Seoul Metropolitan Area conducted 2002 were analysed. It was founded that the walking access times to the subway stations, which can represent their spatial extents, are related to their travel times, but differently according to their given positions in the urban spatial structure. The characteristics of subway commuters also affect them with the conditions. It is to be expected that the results of this research can contribute to an enhancement of its usage by applying to land-use policies of the catchment areas.

The purpose of this study was to analyze usage frequency and importance of competencies which are required to restaurant industry professionals. For this purpose, opinions of restaurant industry professionals on the competency were surveyed using questionnaires. To develop a questionnaire, a total of 27 competency variables which are required to restaurant industry professionals were drawn through literature review. Questionnaires were distributed to 300 professionals in restaurant industry with different positions using random sampling. Out of 300 questionnaires, 221 questionnaires were used for analysis. Statistical analysis was conducted using SPSS 10.0, including descriptive analysis, ANOVA and t-test. Reliability test and factor analysis were also conducted to evaluate the reliability and validity of the questionnaire. As a result, 'attitude and personality' factor was recognized as the most frequently used and the most important competency factor of restaurant industry professionals. Therefore, the competency such as 'sincerity', 'responsibility', 'sense of honesty', 'positive attitude', 'tolerance and justice', should be more emphasized in restaurant management education. The level of current usage and importance of each competency were different according to age, education level, working experience, position, number of employees, type of restaurant and type of management.

Derrick or caterpillar crane is generally used for the long-span/cable-stayed bridge construction by pre-cast segment lifting from over-land or water transportation. The heavy weight of them, however, could make defects on unstable under-construction structure and, furthermore a method of conventional segment transportation is also able to occur additional time and cost. In this study, in order to improve conventional construction method, the newly developed derrick crane is mainly considered. It could be not only eccentrically loadable on constructing girder but having rotatable boom for segment transportation from back-side. A series of construction stage using developed derrick crane is defined and also its numerical analysis is conducted. To reflect load characteristics of developed derrick crane on construction stage analysis, on/out of service load is separately calculated by considering vertical/lateral rotation range of boom and it is loaded on 4 fixed positions of crane. The derrick crane on this study could be time and cost saving solution for cable-stayed bridge construction and also make contributions to construction load reduction in its process.

This essay attempts to read Percy Bysshe Shelley s The Mask of Anarchy by attending to a political agenda that Shelley seeks to propose and embody in the poem. This poem was written as a response to an exceptional political event, the Peterloo Massacre, and thus it is evident that Shelley intended to engage in contemporary politics by writing this poem. As many critics have pointed out, however, the way in which this poem addresses social, plitical issues is ambivalent and even confusing, since it contains many elements that contradict each other, and sometimes its political visions are based on incoherent conceptions. For this reason, this poem has been considered to be a failure as an occasional poem which should provide the reader with a clear direction for political actions. Faced with this critical problem, this essay proposes that the ambivalence this poem reveals-e.g., the confrontation between moderate artistic fantasy and radical tenets-is not a retreat from political activism, as some critics suggested, but a result of its creation and embodiment of a public sphere which invites various social classes and their positions. The mode in which Shelley conceives this unified public sphere in the course of writing The Mask of Anarchy can be interpreted in terms of the following three features. First, this poem underscores the significance of thoughts in constituting a communal space between people, thus asking the reader to participate in this process of thinking on given issues. Second, this poem suggests that people should enlighten each other by engaging in communicative reciprocations. Lastly, the public sphere formulated by the previous two features should incorporate various socio-political agents beyond class boundaries (even oppressors themselves) into its own working field. After explaining how these three features are manifested in the poem, this essay argues that the unified public sphere thus formed in the poem is the very agenda that Shelley aims to propose for the contemporaneous politics and culture. As a conclusion, this essay highlights how Shelley s project of creating a unified public sphere finally failed in contemporary history through observing two contrasting receptions of Shelley s works.

In order to apply the RNN model to the radio fingerprint-based indoor path generation technology, the data set must be continuous and sequential. However, Wi-Fi radio fingerprint data is not suitable as RNN data because continuity is not guaranteed as characteristic information about a specific location at the time of collection. Therefore, continuity information of sequential positions should be given. For this purpose, clustering is possible through classification of each region based on signal data. At this time, the continuity information between the clusters does not contain information on whether actual movement is possible due to the limitation of radio signals. Therefore, correlation information on whether movement between adjacent clusters is possible is required. In this paper, a deep learning network, a recurrent neural network (RNN) model, is used to predict the path of a moving object, and it reduces errors that may occur when predicting the path of an object by generating continuous location information for path generation in an indoor environment. We propose a method of giving correlation between clustering for generating an improved moving path that can avoid erroneous path prediction that cannot move on the predicted path.

Sharing both locations and positions of ships makes it possible to utilize critical item for their safe and efficient navigation in such diversifying meantime environments. AIS is the representative technology for the sharing solutions. The AIS is even used in airspace and ground stations, so that AIS could facilitate the ships' safety navigation and their prevention/rescue from endangers. Due to AIS's many advantages, IMO(International Maritime Organization) made adapting the AIS mandatory for international passenger ships and the ships that are over than 300 tons. AIS uses VHF band areas for transmitting information and the information can be propagated to several hundreds km in range. Due to the large range, AIS monitoring system can acquire huge number of ships, which makes system performance lower and busier. In this paper, we propose the strategy of AIS information extraction for efficient monitoring system. Thus, the monitoring system has higher processing performance and lower network usage. As well as, the proposal affects the monitoring system has more capacity to include other systems' targets, in result.

This study is aimed to analyse the performances and market positions of Korean products at the Central and South America where recently come into the spotlight for the emerging markets with FTA. The main problems were not the communication or geographical distance but the faint Central and South American specific support of the government and indifferent market approaching concepts. New cultural merchandising approach, Korean enterprise can maintain the competitive advantage against with chinese low products which is main opponent in this market. In order to achieve the close cultural approach, Korean enterprise should use the 'elite groups' in the Central and South america whom are multi cultural leaders in there and also needs to use the Korean CQO merchandisers in the Central and South America. And the new FTA with rest of countries in the Central and South America more aggressively will be the inmost objet of maintaining competitive advantage and we could change the concept of the this market from 'big indifferent market' to 'strategic market' as a hopeful market for achieve the diversification of export.

There are numerous structural details (Longitudinal beam, web plate, U-ribs and I-ribs) in the top and bottom plates of steel box girders, which have significant influences on the longitudinal stress (normal stress) distribution. Clarifying the influence of these structural details on the normal stress distribution is important. In this paper, the ultra-wide steel box girder with large cantilevers of the Jinhai Bridge in China, which is the widest cable-stayed bridge in the world, has been analyzed. A 1:4.5 scale laboratory model of the steel box girder has been manufactured, and the influence of structural details on the normal stress distribution in the top and bottom plates for four different load cases has been analyzed in detail. Furthermore, a three-dimensional finite element model has been established to further investigate the influence regularity of structural details on the normal stress. The experimental and finite element analysis (FEA) results have shown that different structural details of the top and bottom plates have varying effects on the normal stress distribution. Notably, the U-ribs and I-ribs of the top and bottom plates introduce periodicity to the normal stress distribution. The period of the influence of U-ribs on the normal stress distribution is the sum of the single U-rib width and the U-rib spacing, and that of the influence of I-ribs on the normal stress distribution is equal to the spacing of the I-ribs. Furthermore, the same structural details but located at different positions, will have a different effect on the normal stress distribution.

The purpose of this paper is to investigate the distribution of /ju/ in British English, especially after the coronal sonorants /n, l, /r/. The sequence /ju/ is related with vowels such as /u/, /ʊ/, and /ʊ/, and has occasioned a variety of conflicting analyses or suggestions. One of those is in which context /j/ is deleted if we suppose that the underlying form is /ju/. The context differs according to the dialect we deal with. In British English, it is known that /j/ is deleted always after /r/, and usually after /l/ when it occurs in an unstressed word-medial syllable. To check this well-known fact I searched OED Online (the 2nd Edition, 1989) for those words which contain /n, l, r/ + /ju, jʊ, u, ʊ, (j)u, (j)ʊ/ in their pronunciations, using the search engine provided by OED Online. After removing some unnecessary words, I classified the collected words into several groups according to the preceding sonorant consonants, the positions, and the presence (or absence) of the stress, of the syllable where /ju/ occurs. The results are as follows: 1) the deletion of /j/ depends on the sonorant consonant which /ju/ follows, the position where it occurs, and the presence of the stress which /ju/ bears; 2) though the influence of the sonorant consonants is strong, the position and stress also have non-trivial effect on the deletion of /j/, that is, the word-initial syllable and the stressed syllable prefer the deletion of /j/, and word-medial and unstressed syllable usually retain /j/; 3) the stress and position factors play their own roles even in the context where the effect of /n, l, r/ is dominant.

This paper aims at reconsidering 'suture,' a key concept in early Lacanian film criticism, with a view to narrowing a supposed gap between early Lacanian and later Lacanian film criticism. Early Lacanian film theorists, among whom Jean-Pierre Oudart, Jean-Louis Baudry, Laura Mulvey and Daniel Dayan, to name a few, are prominent, focus on cinematic signifying system as well as its ideological effects on shaping subjectivity of the audience. Initiated by Jacques-Alain Miller's article on suture as the logic of signifier and grafted into film as the logic of the cinematic by Oudart's writing, the concept of suture was established as a key word in early Lacanian film criticism. In their taxonomy, suture refers to the processes by which the audience are stitched into the story-world of a film. The audience are drawn into the film and take up positions as subjects-within-the-film such that they make sense of and respond to what the film represents as they are encouraged to do so by the film itself. On the other hand, later Lacanian film critics, who are much influenced by Lacan's later emphasis on the Real, focus on concepts such as gaze, petit objet a, fantasy, rather than suture. They are more concerned with the failure of suture and the disruption of the Symbolic than the ideological effects of suture and the consolidation of the Symbolic. They require a break from the previous approach of Lacanian film theory which centers around the Imaginary and the Symbolic. However, early Lacanian and later Lacanian film theory do not manifest as much disparity as they are supposed to do, for both are against the ideological manipulation of suture. Slavoj Žižek, a leading scholar of later Lacanian psychoanalysis, revives the concept of suture as a patch of the Symbolic which covers the gap, if not always successful.
