The purpose of this paper is to examine how Chinese speakers realize Korean prosodic phrases in the reading of Korean texts. Prosodic phrase, in this study, is defined as basic unit of spoken language which can be perceived as purely separate phonetic unit by both hearer and speaker, and is realized with a coherent intonational configuration. Prosodic phrase plays an important role in both speech production and perception. In the second language acquisition, prosody influences the accuracy and fluency of spoken language. The main purpose of this study is to describe the aspect of syntagmatic operation of prosody that produces prosodic phrases. We have specifically examined the relations between the prosodic phrase's boundary and its syntactic status. Furthermore, we examined internal syntactic structure of each prosodic phrase. And the results of each analysis were compared to the aspects of prosodic phrases' formation produced by native Korean speakers. The results show that Chinese speakers tend to coincide the prosodic phrases with syntactic structure more than native Korean speakers.

The clear and specific objective of this study is to design a false news discriminator algorithm for news articles transmitted on a text-based basis and an architecture that builds it into a system (H/W configuration with Hadoop-based in-memory technology, Deep Learning S/W design for bigdata and SNS linkage). Based on learning data on actual news, the government will submit advanced "fake news" test data as a result and complete theoretical research based on it. The need for research proposed by this study is social cost paid by rumors (including malicious comments) and rumors (written false news) due to the flood of fake news, false reports, rumors and stabbings, among other social challenges. In addition, fake news can distort normal communication channels, undermine human mutual trust, and reduce social capital at the same time. The final purpose of the study is to upgrade the study to a topic that is difficult to distinguish between false and exaggerated, fake and hypocrisy, sincere and false, fraud and error, truth and false.

한 편의 시를 대하는 마음은 읽는 이의 감정상태에 따라서 작가가 전달하고자 하는 심상이 각각 다른 빛깔의 색으로 나타난다. 시는 세상과 작가의 세계를 이어주는 텍스트이자 하나의 다리이며 그 관계 속에서 활자를 통한 커뮤니케이션이 일어난다. 현대의 타이포그래피는 인터넷과 영상매체의 발달에 따라 그 응용 범위가 매우 방대하여지고 있으며, 표현방법 또한 다양한 소프트웨어의 지원으로 타이포그래피는 이미 움직이고 변화하여 마치 살아 숨쉬는 듯한 유기적 언어로 거듭나고 있다. 움직임과 시간, 공간을 연출하는 하나의 영상언어로서의 타이포그래피와 유사한 구조적 특성과 한글 글자체 고유의 조형성을 지니고 있다. 특히 기존의 시들이 의미를 함축하고 있으나 서술적 구조를 지니고 있음에 반해, 한글구체시에 나타난 활자는 한글의 고유의 조형성에서 빚어지는 다른 영역의 시이자 하나의 비선형구조의 타이포그래피적 형태를 보이고 있다. 이에 본 연구에서는 한글구체시를 한글 타이포그래피의 조형성과 함께 비선형구조를 분석하여 봄으로써 타이포그래피의 연구 영역을 넓히고, 문학의 시각화의 시도로서 그 의의를 찾을 수 있다.

The variety of document ranking algorithms have developed to provide efficient mining results for user's query on the web environment. The typical ranking algorithms are the Vector-Space Model based on the text, PsgeRank and HITS algorithms based on the hyperlink structures and other several improvement algorithms. All these are for the user's convenience and preference. However, these algorithms are usually developed on then Horizontal and non-hierarchial web environments and are not suitable for the hierarchial web environments such as enterprise and defense networks. Thus, we must consider the special environment factors in order to improve the ranking algorithms. In this paper, we analyze the several typical algorithms used by hyperlink structures on the web environment. We, then suggest a configuration of the hierarchical web environment and also give the relations between agents of the web mining system. Next, we propose an improved ranking algorithm suitable to this kind of special environments. The proposed algorithm is considered both the hyperlink structures of the documents and the location of the user of the hierarchical web.

The Sign system of nursing home plays an important role when an elderly adapts to new environment and gets on daily life autonomously. Common living spaces are expecially important in maintaining social nature, adequate signage should be installed to aid them in finding their ways. Sign system is a comprehensive system consisted of various factors. In this research, it has been categorized as signage and cueing. Signage includes text and graphic signs, and cueing consists of floor plan configuration and sensual mechanism of visual, auditory, olfactory senses. Using this framework, held investigation and analysis were held in common area(shared living room, shared dining room, toilet) of 14 Korean, 8 Northern European, and 10 Japanese nursing home facilities. The result revealed that even though sign system should work as a combined unit, each factor was planed without relations to each other and did not perform mutually complementary role. Signage was installed too high, without considering the posture of elderly. Korean facilities used abundant and diverse signage compared to other countries. Japanese nursing home preferred cueing method over signage, and those of Northern Europe used plentiful visual cues such as color and ornaments.

The talking head (TH) indicates an utterance face animation generated based on text and voice input. In this paper, we propose the generation method of TH with facial expression and intonation by speech input only. The problem of generating TH from speech can be regarded as a regression problem from the acoustic feature sequence to the facial code sequence which is a low dimensional vector representation that can efficiently encode and decode a face image. This regression was modeled by bidirectional RNN and trained by using SAVEE database of the front utterance face animation database as training data. The proposed method is able to generate TH with facial expression and intonation TH by using acoustic features such as MFCC, dynamic elements of MFCC, energy, and F0. According to the experiments, the configuration of the BLSTM layer of the first and second layers of bidirectional RNN was able to predict the face code best. For the evaluation, a questionnaire survey was conducted for 62 persons who watched TH animations, generated by the proposed method and the previous method. As a result, 77% of the respondents answered that the proposed method generated TH, which matches well with the speech.

Contrary to the traditional text-based information, 4S(GIS,GNSS,SIIS,ITS) information can contribute to the citizen's welfare in upcoming era. Recently, GSIS(Geo-Spatial Information System) has been applied and stressed out in various fields. As analyzed the data from GSIS arena, the position information of objects and targets is crucial and critical. Therefore, several methods of getting and knowing position are proposed and developed. From this perspective, Position collection and processing are the heart of 4S technology. We develop 4S-Van that enables real-time acquisition of position and attribute information and accurate image data in remote site. In this study, the configuration of 4S-Van equipped with GPS, INS, CCD and eye-safe laser scanner is shown and the merits of DGPS/INS integration approach for geo-referencing is briefly discussed. The algorithm of DGPS/INS integration fur determination of six parameters of motion is eccential in the 4S-Van to avoid or simplify the complicated computation such as photogrammetric triangulation. 4S-Van has the application of Laser-Mobile Mapping System for three-dimensional data acquisition that merges the texture information from CCD camera. The technique is also applied in the fields of virtual reality, car navigation, computer games, planning and management, city transportation, mobile communication, etc.
