Sosang Pal-Kyung(瀟湘八景), which originated in China and means eight scenes of So River and Sang River, greatly influenced the poems and the pictures in East Asia for a long time and became a cultural phenomenon leading the stereotype of the traditional landscapes in Korea and Japan. Studies on 'Kyung(a scene)' such as 'Pal-Kyung(八景)', have been made continuously until now, but there are no results of a study intensively focusing on the meaning and the form of Sosang Pal-Kyung, which is the origin of the domestic Pal-Kyung culture. The goal of this study is to investigate the typical form observed in Sosang Pal-Kyung-Ga(瀟湘八景歌) and Sosang Pal-Kyung-Do(瀟湘八景圖), as a text of a cultural landscape, and to clear up the coherence structure between a recognition system and a way of thinking that existed in the cultural phenomenon of Sosang Pal-Kyung. In this study, the symbolism of Pal(八) was summarized and the surface structure and the correlation of each Kyung of Sosang Pal-Kyung was explained in light of semiotics through segmenting and disjointing the lexeme of a landscape while the coherence structure and the meaning of Sosang Pal-Kyung-Ga and Sosang Pal-Kyung-Do as a text were investigated. Sosang Pal-Kyung is based on the view of the Sun and the Moon(or Positive and Negative) and the Eight Trigrams(八卦) for divination and is a linguistic symbol in which human life and the principle of circulation and conversion of nature are expressed as characters and picture texts. Its structure has strong coherence and cohesion, which attempt to move the abstruse truth of nature into human consciousness by developing and corresponding the grammatical structure and form of the sentences and the implicative languages emphasizing the symbolism of the words to the characteristics of similarities and contrast. In addition, Sosang Pal-Kyung expresses human life, the processes of birth and death of nature and the mutual response dialectically by putting various factors of the landscape in the frame of regular formality and structure. It is considered that the image signs in Sosang Pal-Kyung emphasize the theory of circulation of human life and nature are narrative scenery, which one looks at with a contemplative view in the circulation system of the time and the season. The cultural phenomena of Sosang Pal-Kyung in the Joseon Dynasty, which had been handed down from the Goryeo Dynasty, had become the driving force of leading aesthetics of Joseon's art and literature by adding the scenery of the point of view of Sung Confucianism. Its coherence structure was changed, but its cohesion was handed down continuously so that it became not only the basic text of the traditional and cultural landscape but also, the typical Korean-style stereotype of a landscape.

The movie content, which is more firmly established as the best popular art, is the main entertainment content that reflects the current trend based on the most common contents and consensus on the culture of the global community. However, since modern films are more sensitive to popular tastes that appeal to amusement and stimulating emotions, reduction of opportunities for intellectual pleasure through appreciation of artistic expressions is inevitable and unavoidable. In this paper, however, we try to analyze the symbolic meaning of the short in the film, to grasp the inner nature of the film projected in the film, and ultimately to express the theme message. Effective symbolism exposes emotions to create moods and moods, and to express deeply with the audience, expressing the inner psychological state and will of the person. By conveying the meaning behind the surface image to the audience unconsciously, it is possible to transmit the message intentionally more effectively and strongly. In addition, it can be expected to create effects such as an associative action or an increase in contrast energy on the screen through collision of irony and image in the expectant emotion composition of the audience.

This paper describes the implementation of HTML converter for wireless internet access in wireless application protocol environment. The implemented HTML converter consists of the contents conversion module, the conversion rule set, the WML file generation module, and the frame contents reformatting module. Plain text contents are converted to WML contents through one by one mapping, referring to the converting rule set in the contents converting module. For frame contents, the first frameset sources are parsed and the request messages are reconstructed with all the file names, reconnecting to web server as much as the number of files to receive each documents and append to the first document. Finally, after the process of reformatting in the frame contents reformatting module, frame contents are converted to WML's table contents. For image map contents, the image map related tags are parsed and the names of html documents which are linked to any sites are extracted to be replaced with WML contents data and linked to those contents. The proposed conversion method for frame contents provides a better interface for the users convenience and interactions compared to the existing converters. Conversion of image maps in our converter is one of the features not currently supported by other converters.

This study used text mining methodology to focus on the perceptions of the landscape embedded in text that users spontaneously uploaded to the "Taean Travel"blogpost. The study area is the Taean Coast National Park. Most of the places that are searched by 'Taean Travel' on the blog were located in the Taean Coast National Park. We conducted a network analysis on the top three places and extracted keywords related to the landscape. Finally, using a centrality and cohesion analysis, we derived landscape perceptions and the major characteristics of those landscapes. As a result of the study, it was possible to identify the main tourist places in Taean, the individual landscape experience, and the landscape perception in specific places. There were three different types of landscape characteristics: atmosphere-related keywords, which appeared in Kkotji Beach, symbolic image-related keywords appeared in Sinduri Coastal Sand Dune, and landscape objects-related appeared in Manlipo Beach. It can be inferred that the characteristics of these three places are perceived differently. Kkotji Beach is recognized as a place to appreciate a view the sunset and is a base for the Taean Coast National Park's trekking course. Sinduri Coastal Sand Dune is recognized as a place with unusual scenery, and is an ecologically valuable space. Finally, Manlipo Beach is adjacent to the Chunlipo Arboretum, which is often visited by tourists, and the beach itself is recognized as a place with an impressive appearance. Social media data is very useful because it can enable analysis of various types of contents that are not from an expert's point of view. In this study, we used social media data to analyze various aspects of how people perceive and enjoy landscapes by integrating various content, such as landscape objects, images, and activities. However, because social media data may be amplified or distorted by users' memories and perceptions, field surveys are needed to verify the results of this study.

Appreciating gardens in garden show has its meaning in appreciating concepts and ideas of artists, hidden inside of garden, as formative arts, as well as the beauty of the nature. This study is aimed to understand the intension of artists in visual expression through formative media in the gardens by assessing structure of visual narrative in the space with 20 artworks among the ones presented in 2018 Taehwagang Garden Show. The formative structure is delivered as contents and forms through formative media and formative language. Thus, for analysis on the artworks, the researcher assessed expressive characteristics of the media, through visual and space language, that forms the formative structure in the contest of narrative structure expressed in the gardens and findings of the analysis are as follows. First, for intertextuality obtained through media image, most of the artworks delivered message through 'figure image.' This means, the concept is delivered as 'affinity of actual objects' through the media and associated 'meaning and meaning action' are expected. Second, the characteristics of signs to show symbolism in the gardens were categorized into 'icon'. 'index' and 'symbol'. The results showed that most of the artworks expressed common characteristics between image and meaning, using 'icon' and 'symbol'. Third, as space formation components, based on formative principles, the components of 'dominant' and 'subordinate' roles were defined as the key components for meaning delivery. Also, it was understood that 'space configuration with overlapped image' and 'space configuration with transparency' were adopted to strengthen conceptional layers. Forth, for space occupation types, there were mostly central hall type, corridor type and passage space type and for open space type, the entire space area was conceptualized, instead of certain object. The circulation line was defined in the frequency order of circular type, pass type and return type. The study on the expressive characteristics of visual narrative in garden design is meaningful as it could build base data for the method of spatial design for visual development of concepts in the future.

In this study we examined the preferences of eight college living factors for students at Korea National College of Agriculture and Fisheries(KNCAF). Analytical techniques of unstructured data used opinion mining and text mining techniques, and the analysis results of text mining were visualized as word cloud. The college life factors included eight topics that were closely related to students: 'my present', 'my 10 years later', 'friendship', 'college festival', 'student restaurant', 'college dormitory', 'KNCAF', and 'long-term field practice'. In the text submitted by the students, we have established a dictionary of positive words and negative words to evaluate the preference by classifying the emotions of positive and negative. As a result, KNCAF students showed more than 85% positive emotions about the theme of 'student restaurant' and 'friendship'. But students' positive feelings about 'long-term field practice' and 'college dormitory' showed the lowest satisfaction rate of not exceeding 60%. The rest of the topics showed satisfaction of 69.3~74.2%. The gender differences showed that the positive emotions of male students were high in the topics of 'my present', 'my 10 years later', 'friendship', 'college dormitory' and 'long-term field practice'. And those of female were high in 'college festival', 'student restaurant' and 'KNCAF'. In addition, using text mining technique, the main words of positive and negative words were extracted, and word cloud was created to visualize the results.

'Hansik', or Korean cuisine is one of Korea national brands. To understand the domestic consumer awareness of Korean cuisine, data was gathered under the keyword search, 'Hansik.' Textom 3.5 was used to gather data from blogs, news media found on Naver from November 1, 2018, to October 31, 2019. The results from frequency and TF-IDF analysis indicate that the 'buffet' had the largest proportion in terms of consumer awareness to Hansik. Also, broadcasting contents starring star chefs had a great influence. The Hansik awareness did not remain in the domains of its traditionality, but also branched into extents into areas such as fusional and gourmet cuisine. UCINET6 and NetDraw were used to conduct CONCOR analysis. Four cluster formations have been found; various food cultural cluster, high-end restaurant cluster referring to aired restaurants on media, Hansik brand cluster, and Hansik buffet cluster. This study proposes presenting a various menu of Hansik which use a multiple number of ingredients. Also, a promotion that introduces fine Hansik and a development of marketing views and media contents about the convenient HMRs make the associated imagery of Hansik to be strengthen.

The information that consumers share in the SNS (Social Networking Service) has a great influence on the purchase of consumers. Therefore, it is necessary to pay attention to new research methodology and advertising strategy using Social Big Data. In this context, the purpose of this study is to quantitatively analyze customer value through Social Big Data. In this study, we analyzed the value structure of consumers for the three smartphone brands through text mining and positive/negative image analysis. Analysis result, it was possible to distinguish the emotional aspects (sensitivity) and rational aspects (rationality) for customer value per brand. In the case of the Galaxy S7 and iPhone 6S, emotional aspects were important before the launch, but the rational aspects was important after release date. On the other hand, in the case of the LG G5, emotional aspects were important before and after launch. We can propose two core advertising strategies based on analyzed consumer value. When developing advertising strategy in the case of the Galaxy S7, there is a need to emphasize the rational aspects of product attributes and differentiated functions. In the case of the LG G5, it is necessary to consider the emotional aspects of happiness, excitement, pleasure, and fun that are felt by using products in advertising strategy. As a result, this study will provide a good standard for actual advertising strategy through consumer value analysis. Advertising strategies are primarily driven by intuition or experience. Therefore, it is important to develop advertising strategies by analyzing consumer value through social big data analysis.
