This study analyzed the science texts covering 'air pressure' and 'wind' in common with every curriculum from the syllabus period to the $7^{th}$ curriculum in terms of Systemic Functional Linguistics. Important findings revealed in this study were as follows: In the aspect of ideational metafunction, the texts including much scientific information were reduced by curriculum revision. Most forms of information were 'definition' and 'fact' rather than 'principle'. In the aspect of interpersonal metafunction, the gap between students and texts were getting closer and the social position of students were concerned gradually by curriculum revisions. In the aspect of textual metafunction, the ratios of technical terminology and notation were reduced, however the amount of texts in science textbooks were reduced as well. While the subject was presented in the early texts, it was omitted as time went on. The consistency of subject and theme were reduced in the $7^{th}$ curriculum remarkably.

Sentiment analysis incorporates natural language processing and artificial intelligence and has evolved as an important research area. Sentiment analysis on product reviews has been used in widespread applications to improve customer retention and business processes. In this paper, we propose a method for performing an intensified sentiment analysis on customer product reviews. The method involves the extraction of two feature sets from each of the given customer product reviews, a set of acoustic features (representing emotions) and a set of lexical features (representing sentiments). These sets are then combined and used in a supervised classifier to predict the sentiments of customers. We use an audio speech dataset prepared from Amazon product reviews and downloaded from the YouTube portal for the purposes of our experimental evaluations.

In the creative economy paradigm, motivation of the opportunity based startup is a continuous concern to policy-makers. Recently, bigdata anlalytics challenge traditional methods by providing efficient ways to identify social trend and hidden issues in the public sector. In this study the authors introduce a case study using social bigdata analytics for conducting policy analysis. A semantic network analysis was employed using textual data from social media including online news, blog, and private bulletin board which create buzz on the startup business. Results indicates that each media has been forming different discourses regarding government's policy on the startup business. Furthermore, semantic network structures from private bulletin board reveal unexpected social burden that hiders opening a startup, which has not been found in the traditional survey nor experts interview. Based on these results, the authors found the feasibility of using social bigdata analysis for policy-making. Methodological and practical implications are discussed.

The main purpose of this paper is to take a look at a controversial approach to critical discourse analysis for the suggestion of a well-balanced perspective on such a biased presupposition and methodology. Currently linguists, language teachers and even social scientists have shown their strong interests in critical language awareness and its ideological involvements in order to encourage the general public to realize the social function of language in all modes of communication. It seems, however, to me to be increasingly clear that critical language study calls for a careful attempt based on an appropriate combination of textual facts and contextual factors in the interpretation of discourses. From this point, of view, this paper suggests some pedagogic / analytical guidelines for a study on language and its social connotations as a result of examining the cogency of two contrasting argumentations in relation to critical discourse analysis.

Purpose Social media such as social network services, online forums, and customer reviews have produced a plethora amount of information online. Yet, the information deluge has created both opportunities and challenges at the same time. This research particularly focuses on the challenges in order to discover and track the service defects over time derived by mining publicly available online customer reviews. Design/methodology/approach Synthesizing the streams of research from text analytics, we apply two stages of methods of sentiment analysis and structural topic model incorporating meta-information buried in review texts into the topics. Findings As a result, our study reveals that the research framework effectively leverages textual information to detect, prioritize, and categorize service defects by considering the moving trend over time. Our approach also highlights several implications theoretically and practically of how methods in computational linguistics can offer enriched insights by leveraging the online medium.

In recent years, main focus of research on image retrieval techniques is on content-based image retrieval. Text-based image retrieval schemes, on the other hand, provide semantic support and efficient retrieval of matching images. In this paper, based on Formal Concept Analysis (FCA), we propose a new image indexing and retrieval technique. The proposed scheme uses keywords and textual annotations and provides semantic support with fast retrieval of images. Retrieval efficiency in this scheme is independent of the number of images in the database and depends only on the number of attributes. This scheme provides dynamic support for addition of new images in the database and can be adopted to find images with any number of matching attributes.

The purpose of this study is to analyze communication between school and parents using the "letters to the parents", in order to examine possible areas of improvement for enhancing educational opportunities and school life adjustment for children from multi-cultural families. The letters to the parents used in elementary schools were analysed through genre analysis specifically for this study. At first, the Korean language textbooks for married female immigrants were investigated to see how many letters to parents were included in them. Second, letters to parents were collected to research their structure and content. They were categorized by the text type according to functions and speech acts. It is expected that the results of this study will be helpful for the Korean language education of married female immigrants.

Objectives : ShangHanLun is a clinical guideline, and its core is in the part of Six-meridian Diseases. In recent philological sutdies, independent textual analysis of Shanghanlun is essential to define the scope of research. Methods : By the textual study, I defined the Shanghanlun clinic model. And I researched about medical range of Shanghanlun, and relations between Shanghanlun and JinGuiYaoLue, and between Shanghanlun and Huangdineijing. Results : In six topic sentences, the word '-之爲' means 'a process'. In provisions following topic sentences, the word '者' means 'a person'. So Shanghanlun is describing processing factors of Six-meridian Diseases and related human changes with clinical therapy. In the philological studies, meaning of '傷寒' was possibly just the 3rd provision of the greater yang disease part. Practically Shanghanlun's study range is over the concept of Cold damage today. Additionally Jinguiyaolue deals diseases, but Shanghanlun deals human. Gangpyeong-Shanghanlun's phrases can be separated into five part, and oldest part is independent of Huangdineijing. Conclusions : So we need to set a new and independent clinic model of Shanghanlun to verify it. The Shanghanlun's clinic model has a 3 steps. 1st step is to find 6 type defined symptoms, which act as processing factors of Six-meridian Diseases. 2nd step is to confirm a human changes after a Disease appeared. 3rd step is to treat a patient as a provision suggests. Philologically Shanghanlun's clinic range is not limited by the word '傷寒'. And many concepts in Shanghanlun should be independent of Huangdineijing.

This paper takes a qualitative approach to examining liveability by analysing the participatory planning proposals delivered by the local residents in Daegu, South Korea. Drawing on the textual resources of the proposals and interview data, the perceived liveability was found to vary across different neighbourhoods, and community cohesion and community capacity building were found highly valued in the liveability discourses in the Korean context. The paper argues that our understandings of liveability should be localised and contextualised at a sub-municipal level. It also highlights that participatory planning can be useful in articulating local communities' perception and experiences of liveability of their immediate localities, particularly in the less attractive and less affluent neighbourhoods in the city.

The aim of this paper is to propose an integrative definition of key account management (KAM) at the organizational level through a content analysis of the existing definitions of KAM available in the business literatures. A representative pool of definitions of key account management was generated through literature review from twenty three journals that covers the divergence of name variety like global account management, strategic account management, national account management, international key account management, key client management, major account management, key customers management and key account management. Relating to the definition of key account management various attributes are identified through content analysis and according to the relevance, profile for each attributes are developed. On the basis of these attributes a diagrammatic and textual definition is proposed that covers the different standpoints and aspects of key account management approach and captures its essence as well. Eventually, several strategic implications are derived that create the field for further empirical investigation.
