Smart Phone with domestic demand increasing rapidly, the utilization of multimedia services have become diverse. Accordingly, Smart Phone users to hack their Jail Breaking and Rooting and illegal use of the multimedia content is copyrighted. Also relevant to mobile communication terminal as a high crime, create, and the digital evidence increases the utilization of the mobile forensic evidence is required to study. In this paper, Smart Phone Copyright Violation and Forensic Apply Method research. Smart Phone Status and related violations of copyright infringement, broadcasting, film, music, e-book, etc. for each survey item, and how to apply for forensics were studied. This study investigated the development and forensic science will be able to contribute to the development.

Currently, under being related with confiscation method of digital store medium from the court of justice, "the sorting confiscation method of principle, the exceptional medium confiscation method" from in section3 no.106 of the criminal procedure code disregard the actual fields of investigation. What is more, there are many difficulties to execute cases by observing this for the achievement of confiscation purpose. At this point, I present the problems of the present confiscation search method and the desirable scene confiscation search method and the improvement program under the new technology circumstance.

기술이 발전함에 따라 컴퓨터 범죄는 점차 증가하고 있으며, 용의자는 사건의 증거가 될 수 있는 파일들에 대해 패스워드 기능을 제공하는 응용프로그램을 활용하여 증거물에 대해 의도적인 접근을 막고 있다. 이로 인해 수사관은 암호화된 파일들에 대해 접근이 매우 어려운 상황이며, 해결 방안으로써 패스워드 복구 프로그램이 대안이 될 수 있다. 하지만 대다수의 패스워드 복구 프로그램들은 단순한 전수조사 공격 방식을 지원하거나 국가별 특징을 고려하지 않은 영문용 사전파일을 적용하여 복구하고 있기 때문에, 국내수사 환경에서 패스워드 검색에 한계가 따르고 있다. 따라서 수사관이 암호화된 파일에 대해 효율적으로 검색할 수 있는 방안이 필요하며, 이를 통해 빠른 시간 내에 증거물을 복구할 수 있는 방안이 강구되어야 한다. 본 논문에서는 최근 국내외 사전구축 사례 및 동향을 조사함으로써 효율적인 패스워드 사전 파일을 구축할 수 있는 방안을 제시하며, 이와 함께 용의자의 개인적인 정보를 이용하여 최적화된 사전파일을 생성할 수 있는 방안에 대해 설명한다.

The historical facts usually remain in the linguistic records. The name of a place has been considered most useful among the records. The name of a place contains lots of information which help us analyzing and explaining the historical problems. The main purpose of this thesis is to account for the relation between language and history based on the data of the name of a place with the property just mentioned above. Firstly I will estimate the territory of the former period of Paek-Che (18B.C.~475A.D.) on the basis of the distribution of the old name of a place and show that the presumed shape of the territory could prove the fact that the unification of Shilla is 'the unification of two nations' but not 'the unification of three nations' Secondly the distribution of the old name of a place can bring light on the interrelation between Paek-Che language and Kara language and help us understand the relation of neighboring countries between two nations. Thirdly we can discuss the relation between the language of the former period of Paek-Che and of the old period of Japan: that is, how the language of Paek-Che came in the Japanese language. Also, the history of cultural domination between Paek-Che and Japan could be clarified if we can prove the linguistic similarity of two nations either to be genealogical relation or to be borrowing one.

The principle of human perception, behavior, and thought is presented in the traditional interface design study that is ease to use and increase the learn-ability. We believe that the usability is related to user's affection. The goal of this paper is to investigate how visual metaphor works in usability and affection in interface to analyse the effect of visual metaphor to user affection. Literature reviews for the concept of metaphor and affection design conducted. We analyse the effect to user's affection through think-aloud i.e. protocol analysis for metaphor.

This paper is based on the Cognitive Linguistics point of view on metaphor. Metaphors are not a matter of language use or rhetorics but of a conceptual frame, where thoughts work. The conceptual frames can highlight one aspect affecting our lives while hiding the other aspect of the facts. Politicians use metaphors to persuade people and justify their political decisions. Lakoff argues that the Republicans in the U.S. have their own conceptual framework based on the 'strict father model' of the conservatives, which can be found in important political speeches. Political metaphors supporting this view are found in the 'Attack on Iraq Speech' by G. H. Bush in 1991 and 'Operation Iraqi Freedom Address' by G. W. Bush in 2003.

This paper discusses a design for Korean language parsing based on subcategorization. First, we discuss some important Korean grammar elements such as syntax category, josa, omi-conjugation, syntactic affix, dependent noun and also discuss subcategorization and expression patterns. Then, we show the basic structure of Korean language parsing process. The first stage scans the input sentence and processes article, noun phrase, numeral, josa, affix, dependent noun, adjective, omi-conjugation, adverb, auxiliary verb. The second stage deals with subcategorization patterns and expression patterns. The third stage processes the clauses and the fourth stage deals with SEA(Sentence Ending+Auxiliary).

기억 인출 단서는 학습을 통해 장기기억 공간에 저장된 정보를 인출하는 과정에서 중요하며, 서로 다른 종류의 기억 인출 단서에 따른 기억 인출 결과 및 이에 대한 인지 학습적 특성 규명은 교육, 범죄 수사, 그리고 인간의 뇌 기능을 모방한 기계학습 연구 등에서 중요하게 다루어져야 할 문제이다. 본 논문에서는 비디오 데이터를 이용하여 학습한 내용을 인출하는 과정에서 텍스트와 이미지가 각각 인출 단서로서 기억인출 결과에 미치는 영향을 분석하고, 기억 정보 및 시각 정보 처리와 관련된 뇌 영역에서의 뇌전도 분석을 이용하여 이를 해석하였다. 실험 결과를 통해 기억 인출을 위해 이미지-텍스트를 제시할 경우 전전두엽의 기억인출 관련 부위와 시각 피질이 위치한 후두엽의 인터랙션이 높게 이루어지면서 암묵적인 시각적기억 표상의 인출이 발생하는 것을 알 수 있었다.

This research derived the perception with, and their remedies, in our country's fire cause investigation system by conducting survey on the working-level officials responsible for fire cause investigation in the fire stations and police stations. The results of the survey showed the necessity of establishing departments exclusively responsible for fire statistics management, broad area fire cause investigation task force, fire appraisal organizations besides National Institute of Scientific Investigation, standards for retaining fire investigation equipment, ways of improving technical education system, and improving the system for those who are specialized in arson (fire) cause investigation.

Codium fragile is commercially farmed in Korea by natural blooming zygote attachment. Experiments found optimum conditions for artificial seed production and nursery culture of C. fragile by asexual reproduction. Isolated utricles and medullary filaments were regenerated to erect thalli using both indoor and outdoor culture experiments. Under the indoor culture conditions, irradiance was an important factor to control the development of erect thalli. Formation of erect thallus from the isolated medullary filaments in the indoor culture was induced after 30 days under $20^{\circ}C$ and $60{\mu}mol/m^2/sec$. The detachment of isolated utricles and medullary filaments from the substrates of seed strings was reduced by exposure to the air during 2 hrs before the indoor culture of seed strings. The maximum growth and development of erect thalli in the nursery culture was induced at a water depth of 0.5 m. Depending on the substrates of the seed strings the growth of erect thalli was not significantly different (p>0.05).
