With the growing number of people that use web services, the perception of the importance of securing web applications is also increasing. There are many different types of attacks that target web applications. In the rapidly-changing knowledge and information society, which came into being with the advancements made in information and communication technology, there is currently an urgent need for building web sites for the purposes of developing one's creativity and character. In this paper, attack schemes that use SQL injections and XSS and target educational digital curation systems which provide educational contents with the aim of developing of one's creativity and character are analyze, in terms of how the attacks are carried out and their vulnerabilities. Furthermore, it suggests ways of dealing appropriately with these web-based attacks that use SQL injections and XSS.

The purpose of this research is to enhance document recognition system which is essential for developing full-text retrieval system of the document image data stored in the digital library of a public institution. To achieve this purpose, the main tasks of this research are: 1) analyzing the document image data and then developing its image preprocessing technology and document structure analysis one, 2) building its specialized knowledge base consisting of document layout and property, character model and word dictionary, respectively. In addition, developing the management tool of this knowledge base, the document recognition system is able to handle the various types of the document image data. Currently, we developed the prototype system of document recognition which is combined with the specialized knowledge base and the library of document structure analysis, respectively, adapted for the document image data housed in National Archives of Korea. With the results of this research, we plan to build up the test-bed and estimate the performance of document recognition system to maximize the utilization of full-text retrieval system.

In this research, we have performed a T-test to see how the relationship between dependent variable or visual point level and independent variable or visual quantity is in order to clear up the correlation between pattern of visual point and visual quantity by the constituents of a view from a different visual point level and the results are as follows: 1) In case of the character of Mt. Uam landscape of the city, Uamsan is set as a fixed point and about a direction of view(D), the north is a datum point from which the range of direction is distributed within 1800 westwardly and the visual range(R) is also within 2000m. An elevation is an average of 7.40 and the average story of the buildings is 3.85. Here the height of a story is about 4m so the average of the visual point difference is estimated at 15.4m. 2) The type of visual point is divided into the intersection group and the front of the highly used public buildings group. Double intersection types account for about 78.80%(52 spots) which forms a majority part of LCP. 3) The analysis of the difference of visual point level divided by eye level and that of the top of the buildings has been proved that there's a sharp difference resulted from t-test at 1 % significant level. The significant difference of elevation from height difference(l5.93m), however, has not been shown. 4) From the result of T-test about visual quantity by the elements of a view from a different visual point level, the visual quantity of mountain(VQM), sky(VQS), ground(VQG) is significant at about 1% each and that of building(VQB) is at about 5%. The difference in visual quantity of a mountain by the visual point level is at about 4% which can meet a marginal level of LCP necessary for evaluation of mountainscape.

The purpose of this study is to analyse the architectural character of JE-DAMG at farm village in Ulsan. JE-DANG means the building for DONG-JE (the sacrificial rite of a village). The regions of this study are KANG-DONG MYEN, and UNG-CHON MYEN in Ulsan. The method of this study is the analysis of them after the actual field surveys of 47 JE-DANGs in these regions The survey contains the area, the height, the period of the erection, the architectural structure, the roof shape, the material, the landowner, SHIN-CHE (means a god's name and shape), DANG-SU tree and so on. Methods of the survey are the field survey, the interview of villager, the analysis of reference data and so on. Results of the study are below. JE-DANGs(buildings) of these regions had been built first in the period of Japanese occupancy and erections of them had continued until 1970's. Since then, they have been rebuilt. The primary JE-DANG is characterized by a tiled roof, a wooden post lintel, a mud-plastered wall, and a wooden door. After rebuilding, characters are a flat slab, a tiled roof, a structure of using red bricks, and the area is getting larger than the primary JE-DANG, but 1 KAN persists without variety. Most of houses in the inland area like UNG-CHON MYEN face the south, and ones in the coastal area like KANG-BONG MYEN face the east. Generally there is DANG-SU tree behind JE-DANG. That proves DANG-SU tree to be the object of the rite. The species of DANG-SU is a pine in general ,but various in UNG-CHON MYEN. In general names of the god are DONG-SHIN , DANG-SAN SHIN and SUNG-HWANG SHIN. I think that the landownership of JE-DANG should change the private ownership into the village ownership to preserve JE-DANG though most of lands of JE-DANG are private ones.

Software internationalization, the process of making software easier to localize for specific languages, has deep implications when applied to speech technology, where the goal of the task lies in the very essence of the particular language. A greatdeal of work and fine-tuning has gone into language processing software based on ASCII or a single language, say English, thus making a port to different languages difficult. The inherent identity of a language manifests itself in its lexicon, where its character set, phoneme set, pronunciation rules are revealed. We propose a decomposition of the lexicon building process, into four discrete and sequential steps. For preprocessing to build a lexical model, we translate from specific language code to unicode. (step 1) Transliterating code points from Unicode. (step 2) Phonetically standardizing rules. (step 3) Implementing grapheme to phoneme rules. (step 4) Implementing phonological processes.

Most morphological analysis methods require repetitive procedures of input character code conversion, segmentation and lemmatization of constituent morphemes, filtering of candidate results through looking up lexicons, which causes run-time inefficiency. To alleviate such problem of run-time inefficiency, many systems have introduced the notion of 'pre-analysis' of words. However, this method based on pre-analysis dictionary of surface also has a critical drawback in its practical application because the size of the dictionaries increases indefinite to cover all words. This paper hybridizes both extreme approaches methodologically to overcome the problems of the two, and presents a method of morphological analysis based on pre-analysis of partial words. Under such hybridized scheme, most computational overheads, such as segmentation and lemmatization of morphemes, are shifted to building-up processes of the pre-analysis dictionaries and the run-time dictionary look-ups are greatly reduced, so as to enhance the run-time performance of the system. Moreover, additional computing overheads such as input character code conversion can also be avoided because this method relies upon no graphemic processing.

This paper is a study of the possibility of experience and expression in the architecture of Louis I. Kahn by focusing on the characters of entrance, court and window/wall of his public buildings. In the course of composition, Kahn defined the entrance, court and window/wall as an connecting elements and elements of boundary. The characters revealed by these elements or rooms give the clue to insight Kahn's thought of relation of interior and exterior space or inner and outer space. Following are the characters of these elements. First, a entrance reveals the fact that inner space separates from outer space by connecting these two space and giving the value to inner space as the entity and totality like outer space. The entrance gives its ontological being to human subjects not by vision but experience and expression which is the essence of commonness, that is, Silence. Kahn made the possibility of activity amplify in this common and silent space. Second, this entrance is connected with wide and huge central space not individual spaces of interior space. This extreme procedure of entering makes human subject feel sublime of intoner space. And the central spaces becomes another exterior or another world in the inner world of architecture by the lights from above and by having the boundary wall which shows same pattern of exterior wall. Third, Kahn regarded a window as the giver of lights not as the medium of vision connecting inner space with outer. He tried to connect interior with exterior through the being and character of the light expressed in the interior. And in his buildings, interior space is connected with exterior by expressing the purpose of building, composition of inner space, structural truth and construction facts through the Form, a pattern of wall, details and ornamental joints. By practicing this thoughts in the real buildings, Kahn tried to gave aura to both the interior space and entity of architecture which is regarded as micro universe like flowers, rocks and human beings.

This study aims to look closely picture books regarding bullying and to analyze people directly involved in resolution to bullying problems and conflict-coping method in those picture books. 71 picture books on bullying were examined in this study. Results are as follows: (1) As person directly involved in resolution to bullying problems, 'victim by himself' settles a conflict situation over half of the books, followed by 'victim and other character' and 'other character alone'. (2) various types are described relatively evenly such as 'getting positive mind or building confidence', 'distancing bullies group or making new friends', 'gaining recognition by showing one's competence off', 'helping bullies or being nice to bullies' for conflict-coping method to bullying problems. In conclusion, the necessity of community effort rather than an individual's own effort to solve bullying problems and possibilities of teaching of language use in those books were discussed.

This article attempts to propose the control planning of townscape color around the historic and cultural heritages. The streets and roads of historic conservation and the changing perspectives to which it gives rise in Stockholm has changed dramatically during this century. New development or changes to existing buildings should be carried out in a way which acknowledges its surroundings and is a good neighbour, both in the cultural and social sense that makes good color design sense. There are many examples of townscape color, but the conservative and the historical streets and roads in the whole of the Stockholm city should benefit from careful design of the environment. To achieve this purposes, some strategies of case study of several streets and roads are reviewed; designing color context to relate to urban architectural design proposals of specific sites of cultural heritages are explored. In all new developments the scale of new buildings and the material finishes and colors used should respect the character of their surroundings and have due regard to the setting of any listed building. Streetscape color of visual assessment proposals should aim to help assimilate the development into the local scene. Important streets and roads should also include color townscape.
