기계 독해(Machine reading comprehension)는 주어진 문맥을 이해하고, 질문에 적합한 답을 문맥 내에서 찾는 문제이다. Simple Recurrent Unit (SRU)은 Gated Recurrent Unit (GRU)등과 같이 neural gate를 이용하여 Recurrent Neural Network (RNN)에서 발생하는 vanishing gradient problem을 해결하고, gate 입력에서 이전 hidden state를 제거하여 GRU보다 속도를 향상시킨 모델이며, Self-matching Network는 R-Net 모델에서 사용된 것으로, 자기 자신의 RNN sequence에 대하여 어텐션 가중치 (attention weight)를 계산하여 비슷한 의미 문맥 정보를 볼 수 있기 때문에 상호참조해결과 유사한 효과를 볼 수 있다. 본 논문에서는 한국어 기계 독해 데이터 셋을 구축하고, 여러 층의 SRU를 이용한 Encoder에 Self-matching layer를 추가한 $S^2$-Net 모델을 제안한다. 실험 결과, 본 논문에서 제안한 $S^2$-Net 모델이 한국어 기계 독해 데이터 셋에서 EM 65.84%, F1 78.98%의 성능을 보였다.

In this paper, we propose a revised Deep Convolutional Neural Network (DCNN) model to extract Protein-Protein Interaction (PPIs) from the scientific literature. The proposed method has the merit of improving performance by applying various global features in addition to the simple lexical features used in conventional relation extraction approaches. In the experiments using AIMed, which is the most famous collection used for PPI extraction, the proposed model shows state-of-the art scores (78.0 F-score) revealing the best performance so far in this domain. Also, the paper shows that, without conducting feature engineering using complicated language processing, convolutional neural networks with embedding can achieve superior PPIE performance.

In this paper, It is studied to control and to monitor the remote system state using HTTP(Hyper Text Transfer Protocol) object communication. The remote control system is controlled by using a web browser or a application program. This system is organized by three different part depending on functionality-server part, client part, controller part. The java technology is used to composite the server part and the client part and C language is used for a controller. The server part is waiting for the request of client part and then the request is reached, the server part saves client data to the database and send a command set to the client part. The administrator can control the remote system just using a web browser. Remote part is worked by timer that is activated per 1 second. It gets the measurement data of the controller part, and then send the request to the server part and get a command set in the command repository of server part using the client ID. After interpreting the command set, the client part transfers the command set to the controller part. Controller part can be activated by the client part. If send command is transmitted by the client part, it sends sensor monitoring data to the client part and command set is transmitted then setting up the value of the controlled system.

With the recent development of the ubiquitous computing technology, there are increasing interest and research in technologies such as sensors and RFID related to information recognition and location positioning in various ubiquitous fields. Especially, RTLS (Real-Time Locating Services) dealing with spatio-temporal data is emerging as a promising technology. For these reasons, the ISO/IEC published RTLS standard specification for compatibility and interoperability in RTLS. Therefore, in this paper, we designed and implemented Spatio-temporal Query Processing Systems for efficiently managing and searching the incoming Spatio-temporal data stream of moving objects. Spatio-temporal Query Processing Systems's spatio-temporal middleware maintains interoperability among heterogeneous devices and guarantees data integrity in query processing through real time processing of unceasing spatio-temporal data streams and two way synchronization of spatio-temporal DBMSs. Web Server uses the SOAP(Simple Object Access Protocol) message between client and server for interoperability and translates client's SOAP message into CQL(Continuous Query Language) of the spatio-temporal middleware.

The data accumulated in this database will be used to develop a speaker identification system. This may also be applied towards, but not limited to, fields of phonetic studies, sociolinguistics, and language pathology. We plan to supplement the large-scale speech corpus next year, in terms of research methodology and content, to better answer the needs of diverse fields. The purpose of this study is to develop a speech corpus for standard Korean speech. For the samples to viably represent the state of spoken Korean, demographic factors were considered to modulate a balanced spread of age, gender, and dialects. Nine separate regional dialects were categorized, and five age groups were established from individuals in their 20s to 60s. A speech-sample collection protocol was developed for the purpose of this study where each speaker performs five tasks: two reading tasks, two semi-spontaneous speech tasks, and one spontaneous speech task. This particular configuration of sample data collection accommodates gathering of rich and well-balanced speech-samples across various speech types, and is expected to improve the utility of the speech corpus developed in this study. Samples from 639 individuals were collected using the protocol. Speech samples were collected also from other sources, for a combined total of samples from 1,012 individuals.

To estimate a performance of MIM's a network modeling method and a simulation algorithm are proposed, and this algorithm is programmed by C language. Especially, state variables are defined to process many concurrent requests ar inputs and a data structure, which contains network informations, is proposed to keep track of each stage. This simulation can be applied to computers which are designed for sequential processing. This method can be used to estimate a performance of MIN's instead of using complex mathematical method.

The Multi-cultural Family Support Center provides various educational programs and services for multi-cultural families. However, there are controversies regarding integration and assimilation, ethnic identity and ethnocentrism, and state-sponsored multi-culturalism. From the home economist's perspective, it was necessary to explore the direction of integration of family life culture in the multi-cultural society. This study concluded that there is a necessity to accept foreign culture and create a new culture while still maintaining their and our own cultural identity respectively. For this purpose, integration and assimilation must progress side by side to maintain the cultural identity and stability of multi-cultural families. But, women migrants are to adapt in their everyday life, they need to attend a Korean-language course and take part in a traditional Korean culture program such as having an assimilational characteristics. Also for the happiness of multi-cultural families ultimately not for the confronted problems, it requires sometimes education of changing migrants' own traditional customs and life culture partly. In this sense, educational and cultural programs held by Multi-Cultural Family Support Center are meaningful and their importance in adapting into everyday life must be recognised by all of us.

웹 서비스 기반의 비즈니스 프로세스 관리 시스템은 트랜잭션에 대한 신뢰도의 확보를 위하여 트랜잭션 관리가 필요하다. 트랜잭션 관리를 위한 여러 트랜잭션 프로토콜들이 제시되었지만, 다양한 프로토콜들은 서로간의 이질성으로 인해 비즈니스 프로세스 관리 시스템들 간의 상호호환을 저해한다. 이를 해결하기 위하여 본 연구에서는 시맨틱스 기반의 트랜잭션 프로토콜을 제안한다. 시맨틱스 기반의 트랜잭션 프로토콜은 상태와 메시지에 대한 정적 시맨틱스(Static Semantics)와 상태 전이에 관한 동작 시맨틱스(Operational Semantics)로 구성된다. 정적 시맨틱스는 프로토콜의 상태와 메시지를 Web Ontology Language(OWL)을 사용하여 온톨로지 기반으로 정의한 모델로서, 트랜잭션 프로토콜에 대한 상호 이해도를 높일 수 있을 것으로 기대된다. 동작 시맨틱스는 비즈니스 트랜잭션의 상태전이를 Abstract State Machine(ASM)으로 정의한 모델로서, 트랜잭션 실행에 대한 자동화와 체계적인 모니터링을 지원할 것으로 기대된다. 트랜잭션 프로토콜들간의 상호호환을 위하여 이러한 정적 시맨틱스와 동작 시맨틱스를 기반으로 하여 각 트랜잭션 프로토콜 및 중립 트랜잭션 프로토콜의 시맨틱스를 정의한다. 정의된 각 트랜잭션 프로토콜의 정적 시맨틱스는 중립 트랜잭션 프로토콜의 정적 시맨틱스와 온톨로지 기반의 매핑 관계를 형성한다. 중립 트랜잭션 프로토콜의 정적 시맨틱스를 매개로 한 온톨로지 매핑은 각 트랜잭션 프로토콜들 간의 상호호환을 지원할 것으로 기대된다.

This paper examines nursing professionals' English abstract to learn their preferences towards tense and voice choices. A total of 24 abstracts, completed reviews to be published by the editorial board members of the Korea Industrial Nursing Association, were analyzed for the study. Each sentence in the four parts of the abstract (Purpose, Methods, Results, and Conclusion) was examined and classified into active/passive voices, and present/past/present perfect tenses. Verbs were then further identified to see which ones were commonly preferred to state the objectives of the study, methods, and to draw conclusions. Hedging expressions in Conclusion were also examined. The results of the present study revealed that Purpose was mostly (79%) stated in the past tense with slight use (17%) of the present tense in the form of 58% active and 42% passive voice whereas Methods were dominantly (96%) illustrated in the past tense with preference of mixed active and passive voice. The Results were also preferably (92%) stated in past tense and Conclusion in both present and past tense. Verbs used by these nursing professionals seemed diverse; however, hedging appeared to be narrowly limited to a few expressions including suggest and should. More diverse English hedging expressions need to be taught at least college level writing so that the EFL learners and writers can have a better understanding of presenting statements in an appropriate level of caution, confidence, or uncertainty.

Currently a KTX train of 20-car formation is 388m long and carries 931 passengers including one captain and three crews which is quite a few to cover the lengthy service area and many customers. On the other hand, if a passenger wants to talk to an attendant, he has to wait for an attendant passing by his/her seat or walk to an intercom which is placed at every other car. Any of these choices is inconvenient. So, in this paper, we presented a system design for developing an audio/visual communication system for a passenger and an attendant. The system was analyzed and designed according to the Object-Oriented methodology with UML (Unified Modeling Language). Based on a problem statement, a Use-case Diagram, Sequence Diagrams, Class Diagram, State Charts, collaboration Diagram were generated. The design will be used in system implementation to a HEMU-400X test train and to be tested.
