오늘날 기계번역 Maschinelle Ubersetzung은 가속적인 발전선상에 놓여있다. 지난 10년 간 컴퓨터로 영어를 타국어로 번역하는 수준은 괄목할 만하다. 본 논문은 기계번역에 있어서 주제어 Topik 및 초점어 Fokus를 중심으로 발생하는 언어학적인 문제점, 특히 의미론적인 문제점을 다루었다 이를 위해 먼저 주제어와 초점어에 대한 언어학적인 개념을 다루어 보았다. 주제어란 한 문장에서 이미 알려진 사항, 즉 이미 주어진 단어이고, 초점어는 한 문장에서 새로운 사항, 즉 지금 전달하고자 하는 내용을 뜻한다 제 3장에서는 주제어와 초점어를 번역하기 위해 생성된 규칙들에 근거한 담화모델 Diskursmodell을 살펴보았다. 제 4장에서는 문장을 번역하는데 있어서 의미론상 발생하는 문제점들을 다루었다 그 문제점들은 다음과 같은 3가지로 요약될 수 있다: 첫째, 문장에서 부정형이 어디에 위치하느냐에 따라 문장의 의미가 달라진다. 둘째, 양화사 Quantor의 형태에 따라 문장의 의미가 달라진다. 셋째, 의문문과 화답문 Antwortsatz에 있어서 어느 내용을 강조하느냐에 따라 문장의 의미가 달라진다. 예를 들어 독일어는 단순히 단어의 위치만 변화시킬 수 있지만 다른 유럽어나 영어는 다른 방법들이 필요한 셈이다. 본 논문에서 제시되고 있는 기계번역의 규칙들은 주제어와 초점어에 관계되는 한 영어와 독일어에 한정되어 제시되었지만, 향후 한국어와 독일어의 기계번역을 위해 밑거름이 되리라 생각한다.

In this paper, functional architecture for fare payment is designed that enables IT developers to create charge-related applications using telecommunications network elements. To support a business model that enables operators to offer integrated billing, a payment and an account management API is crucial. Using this model, a fare payment service consisting of a payment service and an account management service was created. Each service is based on the architecture of parlay X web services. For the modeling of payment and of account management, the new operation of "split charging" is required in Parlay X payment web services, as is the new operation "notification".

This paper presents the model that integrates an SDL system and a CORBA system using mapping rules between method and signal for developing embedded systems connected with internet. In order to support communication between the two different systems (SDL and CORBA), it is essential to secure the conversion interface between SDL communication protocol and CORBA communication protocol. In this paper, IDL is adopted for the communication interface and the conversion of the communication protocol between the two systems, and the IDL compiler automatically generates the interface for protocol interoperability. The proposed model adopts middleware on the subpart of the SDL based legacy system, and hence, supports the service on the distributed system, regardless of the environment and location of the server system.

As the finite element method has become a considerable and effective design tool in ship structural analysis, modeling of three dimensional finite element mesh is more necessary than before. However, the unique style and complexity of a ship usually make the modeling be hard and costly. Although most pre-processor of FEM software and geometric modeler provides modeling function, the capability is quite limited for complicated structure. In order to perform FEM modeling quickly, it is necessary to extract, rearrange, and formalize data from ship design database for partially automatic mesh generation. In this paper, the process of designing relational data tables from design data is shown as a part of analysis automation with the application of engineering database concept.

정서적 지원 대화를 위한 챗봇 개발 시, 사용자의 챗봇에 대한 사용성 및 대화 적절성을 높이기 위해서는 사용자 감정에 적합한 지원 콘텐츠를 제공하는 것이 중요하다. 이를 위해, 본 논문은 사용자 입력 텍스트의 감정 강도 예측 모델을 제안하고, 사용자 발화 맞춤형 정서적 지원 대화에 적용하고자 한다. 먼저 입력된 한국어 문장에서 키워드를 추출한 뒤, 이를 각성도 (arousal)과 긍정부 정도(valence) 공간에 투영하여 키워드가 내포하는 각성도-긍정부정도에 가장 근접한 감정을 예측하였다. 뿐만 아니라, 입력된 전체 문장에 대한 감정 강도를 추가로 예측하여, 핵심 감정 강도 - 문맥상 감정강도를 모두 추출하였다. 이러한 통섭적 감정 강도 지수들은 사용자 감정에 따른 최적 지원 전략 선택 및 최적 대화 콘텐츠 생성에 공헌할 것으로 기대한다.

This paper is implementation of cellular automata neural network system using evolving hardware concept. This system is a living creatures'brain based on artificial life techniques. Cellular automata neural network system is based on the development and the evolution, in other words, it is modeled on the ontogeny and phylogney of natural living things. The phylogenetic mechanism are fundamentally non-deterministic, with the mutation and recombination rate providing a major source of diversity. Ontogeny is deterministic and local physics. Cellular automata is developed from initial cells, and evaluated in given environment. And genetic algorithms take a part in adaptation process. In this paper we implement this system using evolving hardware concept. Evolving hardware is reconfigurable hardware whose configuration si under the control of an evolutionary algorithm. We design genetic algorithm process for evolutionary algorithm and cells in cellular automata neural network for the construction of reconfigurable system. The effectiveness of the proposed system if verified by applying it to Exclusive-OR.

This paper suggested a way to solve the problems by using domain experts who are already in the significant level of knowledge in those fields. For the purpose of achieving our goal, a very simple and efficient approach to construct the knowledge-base which can play an important role in providing researchers with essential information in need was proposed. In addition, the Adaptive R&D Information Service Portal with a new schema structure and a construction method of representing expert's knowledge efficiently was developed. With the simplicity and expandability of the proposed system it can be a good model for a similar system to be developed.

This paper proposes a reliable data sharing scheme on the internet of vehicles (IoV) by utilizing blockchain technology for constructing a decentralized system approach. In our model, to maintain the credibility of the information messages sent by the vehicles to the system, we propose a reputation rating mechanism, in which neighboring vehicles validate every received information message. Furthermore, we incorporate an incentive mechanism based on smart contracts, so that vehicles will get certain rewards from the system when they share correct traffic information messages. We simulated the IoV network using a discrete event simulator to analyze network performance, whereas the incentive model is designed by leveraging the smart contract available in the Ethereum platform.

This study is to find the new method for authority control in Korea by surveying status of authority control in university libraries and by analyzing international conceptual model of authority control and VIAF. 2 kinds of survey were done: one is for libraries having authority records and the other is for libraries not having authority records. In survey result, libraries that have authority records want to sustain their own forms of authorized access points and libraries that have no authority records want the rules related to authority and the national cooperative authority control system to be constructed. Based on ICP 2009, FRAD conceptual model, VIAF and this survey result, new authority control is to respect the diversity of forms of the authorized access points. New authority control is to permit authority records that reflect provision for linguistic or cultural environments of each library, confirming to the national cataloging code. Therefore, authorized access points will be displayed according to user preferred forms. For this new authority control, it is needed to make national authority rule, to build the authority records according to library's own rules, and to construct the cooperative authority control system. Also for user preferred authority control, it is needed to describe detailed elements for authority control and relation data between authorized access points, between authorized access points and variant forms. This study could contribute to suggest new authority control that could accept all kinds of authorized access points preferred by nation, libraries, and users.

Most of a BIPVS (Building Integrated Photovoltaic System) is installed on the rooftop or wall of a building. Therefore, the main factor to consider for selecting the installation site is the shadow effects produced by the surrounding buildings. On the other hand, when the photovoltaic was installed on soundproof walls, shadow effects were produced by not only surrounding buildings but also the surrounding trees. Therefore, a different data model and algorithm with the BIPVS case are essential for proper installation sites selection of a SIPVS (Soundproof wall Integrated Photovoltaic System). This paper deals with the DSM (Digital Surface Model)-based proper installation site analysis for SIPVS. First, the solar incident and altitude angles of the installation candidate sites (solar panel) during the year were calculated. Second, the shadow effects (shadowed or unshadowed) were determined for the candidate sites at each time with the DSM. Third, the amount of solar radiation was calculated with the incident angle for the candidate sites at an unshadowed period. The proper installation site of the SIPVS could then be selected by comparing the accumulated annual solar radiation for each candidate. The proposed algorithm was implemented as a prototype (Java program). From the experiment, the order of the installation suitability was determined among the nine candidates. The proposed algorithm could be used for proper BIPVS installation site analysis aimed at the lower part of a building and calculation of the expected power production.
