  • Most of prior works on testing parallel programs have concentrated on how to guarantee the reproducibility by employing event traces exercised during executions of a program. Consequently, little work has been done to generate test cases, especially, from specifications produced from software development process. In this research work, we devise the techniques for deriving test cases automatically from the specifications written in Message Sequence Charts(MSCs) which are widely used in telecommunication areas and develop the testing environment for performing module testing of parallel programs with derived test cases. For deriving test cases from MSCs, we have to uncover the causality relations among events embedded implicitly in MSCs. For this, we devise the methods for adapting vector time stamping to MSCs, Then, valid event sequences, satisfying the causality relations, are generated and these are used as test cases. The generated test cases, written in TTCN, are translated into CHILL source codes, which interact with a target module to be tested and test the validity of behaviors of the module. Since the testing method developed in this research work extracts test cases from the MSC specifications produced front telecommunications software development process, it is not necessary to describe auxiliary specifications for testing. In audition adapting vector time stamping generates automatically the event sequences, the generated event sequences that are ones for whole system can be used for individual testing purpose.

  • As the expansion of the cultural industry expands, various competitive structures are formed and the methodologies for producing commercial success are being discussed. Among them, Hollywood studios use political relationships and apply ideologies that can produce the best interests. Also, they use a structure that can convey this ideology, which is a mythology. The myth has satisfied the public for a ling time. Campbell suggested that strategies come from the myth, and the ideology emerged as a result of what mythology has to do with existing powers. Disney and Dream Works use the mythology and combine their own values into ideology. Disney and Dream Works choose conflicting ideologies in a different growth background. If Disney is recognized as an educational animation by the ruling class, Dream Works are supported by the public for their actions against Disney. Disney has conservative and patriotic personality, Dream Works is more liberal and progressive. Disney's structure came out first, and Dream Works parodied it. So we can compare Disney and Dream Works with similar myths to create a storytelling structure that embodies ideology. As a result, Disney and Dream Works have been choosing the 9 stages the key of Ideology form the 17 stages of the mythology and reduced them to the introduction, growth and completion. In the first units of the introduction, Disney dealt with the subject of social leaders who sacrificed to the ruling class and Dream Works hinted at the overthrow of the ruling class through the irony. If Disney had deployed colored races in the main characters, Dream Works used a variety of races from the main characters to others. In the second units of growth, Disney organized the process of accepting the value of the ruling class, and Dream Works showed the individual values, not the values of society. In the third units completion, Disney showed the main character who live in the world of the ruling class rebuilded, and Dream Works removed the ruling class and went back to the Individual life. Through the structure of Disney and DreamWorks, we learned how to utilize the mythical structures that transform according to ideologies. The right way to organize works will require the strategic approach to storytelling.

  • This study aims to compare and analyze the environment of natural parks and Ulleung island using the plant taxa classified by five degrees based on their distributional ranges. The scores differentially given based on the importance of each degree; taxa belonging to the fifth degree are given to 20 scores each, fourth 10, third 5, second 3.3, and first 2.5, respectively. The total assessed scores were ranked as Mt. Halla, Seorak, Jiri, Deokyu, Is. Ulleung, Mt. Sobaek, Odae, Palgong, Chink, Taebaek, Songni, Juwang, Gaya, Duryun, Gaeryong, Bukhan, Naebyeon, Worak, Naejang, Cheongryang, Naeyeon, Myeongii, Jokye, Mudeung, Wolchul, Geumo, Juheul, Biseul, Hwangmae, Jangan, Seonun, Moak, Seonam, Chilgap, and Gibaek, in order, respectively. It is suggested that the natural environments assessing more than 1,000 of total scores such as Mt. Halla and Mt. Deokyu are regarded as the most excellent ones, and those between 700 to 1,000 of total scores such as Is. Ulleung and Mt. Odae are regarded as relatively excellent ones. Natural parks scored between 500 to 700 such as Mt. Palgong and Mt. Gaya are regarded as good ones and parks scored between 300 to 500 such as Mt. Duryun and Mt. Mudeung are regarded as normal ones. The area assessed less than 300 of total scores such as Mt. Wolchul and Mt. Gibaek are regarded as the most inferior ones. The total scores of the national parks are generally higher than those of the provincial and county parks. In addition, Ulleung island has a total of 882.9 scores. Therefore, according to the IUCN the Ulleung island should be included in the criterion of the preservative model of natural ecosystem, suggested by Ministry of Environment. At the same time, Ulleung island should be included to the superior model of natural scenery resources by its uniqueness of topography, geography and natural environments. Ulleung island is assessed as having relatively excellent natural environments as compared with other national parks, suggesting that the island should be designated as a new national park.

  • In this paper, we studied the OCT(Optical Coherence Tomography) system which it has been extensively studied because of having some advantages such as high resolution cross-sectional images, low cost, and small size configuration. A basic principle of OCT system is Michelson interferometer. The characteristics of light source determine the resolution and the transmission depth. As a results, the light source have a commercial SLD with a central wavelength of 1,285 nm and FWHM(Full Width at Half Maximum) of 35.3 nm. The optical delay line part is necessary to equal of the optical path length with scattered light or reflected light from sample. In order to equal the optical path length, the stage which is attached to reference mirror is moved linearly by step motor And the interferometer is configured with the Michelson interferometer using single mod fiber, the scanner can be focused of the sample by using the reference arm. Also, the 2-dimensional cross-sectional images were measured with scanning the transverse direction of the sample by using step motor. After detecting the internal signal of lateral direction at a paint of sample, scanner is moved to obtain the cross-sectional image of 2-demensional by using step motor. Photodiode has been used which has high detection sensitivity, excellent noise characteristic, and dynamic range from 800 nm to 1,700 nm. It is detected mixed small signal between noise and interference signal with high frequency After filtering and amplifying this signal, only envelope curve of interference signal is detected. And then, cross-sectional image is shown through converting this signal into digitalized signal using A/D converter. The resolution of the OCT system is about 30$\mu\textrm{m}$ which corresponds to the theoretical resolution. Also, the cross-sectional image of ping-pong ball is measured. The OCT system is configured with Michelson interferometer which has a low contrast because of reducing the power of feedback interference light. Such a problem is overcomed by using the improved inteferometer. Also, in order to obtain the cross-sectional image within a short time, it is necessary to reduce the measurement time for improving the optical delay line.

  • 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.

  • By philological geography method for dismantling and reconstituting Buyeo's Palkyung(扶餘 八景), which best signify the image of ancient city Buyeo's landscape, this research is to demonstrate the fact that the place's inertia of certain historic sites has been passed down as a type of geographic code. Titled poems and retrospective poems about Buyeo's Palkyung and its spectacles and landscapes reveal the fact that the splendid and glorious cultural heritage of Baekje had faded but its traces have remained in the each eight views including Nakhwa-am(落花巖), Goran-sa(皐蘭寺), and Jayong-dae(釣龍臺). In addtion, the spectacles and historic sites of Buyeo's Palkyung appear as the symbol of Baekje's fall and loss in the poems. Thus, it can be said that Buyeo's culture and civilization have never escaped from the cultural and historical scars of Baekhe's fall, being dominated by the place's inertia originated from the identity as "Baekje'slastcapital". It is ironical that Buyeo's future development and prosperity are not free from its cultural and historical spectacles which bear the image of the fall of Baekje. 'Older Buyeos' Palkyung(扶餘舊八景)' and, Prior Buyeo's Palkyung(夫餘前八景), originate from nine views of an unknown builder and after the construction of pavilions and towers, 'Subuk-jeong eight views(水北亭八景)' by Heungguk Kim(金興國) and the eight poems of the, Retrospect of Buyeo(扶餘懷古八景), were created. 'Buyeo's later Palkyung(扶餘後八景), which are especially free from the site's inertia are known to have expanded the scope of Buyeo's landscape by deliberately demonstrating spectacles and sites different from those of existing views. Nakhwa-am, Goran-sa, Joryong-dae, Songwal-dae(送月臺), Youngwal-dae(迎月臺), and Pyungje-tap(平濟塔) are all located within a one kilometer radius of Banwol-sung(半月城), Buyeo's palace and the Baekma river(白馬江), Daewang-po(大旺浦), Busan(浮山) in a two kilometers radius. Jaon-dae(自溫臺), Subuk-jeong(水北亭), and Gyuam-jin(窺岩津) are located within a three kilometers radius. Even Chunjeong-dae(天政臺), which are located within a four kilometers radius of Banwol-sung are located alongside the Baekma river. This indicates the fact that these spectacles had not been established temporarily or impromptu but for a long period time by historic retrospect and the inertia of landscape's geographic cycle. In conclusion, the geographic phenomenon of historical and cultural inertia appeared because Buyeo had the geographic message of "fallen, ancient city". Therefore, Buyeo's Palkyung which have constant retrospective inertia is clearly an geographic code effective and helpful to understand not only the characteristics of historic sites and spectacles of Buyeo in the Sabi period but also the quality of the site itself.

  • The use of new technology greatly shapes the marketing strategies used by companies to engage their consumers. Among these new technologies, social media is used to reach out to the organization's audience online. One of the most popular social media channels to date is the microblogging platform Twitter. With 500 million tweets sent on average daily, the microblogging platform is definitely a rich source of data for researchers, and a lucrative marketing medium for companies. Nonetheless, one of the challenges for companies in developing an effective Twitter campaign is the limited theoretical and empirical evidence on the proper organizational usage of Twitter despite its potential advantages for a firm's external communications. The current study aims to provide empirical evidence on how firms can utilize Twitter effectively in their marketing communications using the association between brand personality and brand engagement that several branding researchers propose. The study extends Aaker's previous empirical work on brand personality by applying the Brand Personality Scale to explore whether Twitter brand communities convey distinctive brand personalities online and its influence on the communities' level or intensity of consumer engagement and sentiment quality. Moreover, the moderating effect of the product involvement construct in consumer engagement is also measured. By collecting data for a period of eight weeks using the publicly available Twitter application programming interface (API) from 23 accounts of Twitter-verified business-to-consumer (B2C) brands, we analyze the validity of the paper's hypothesis by using computerized content analysis and opinion mining. The study is the first to compare Twitter marketing across organizations using the brand personality concept. It demonstrates a potential basis for Twitter strategies and discusses the benefits of these strategies, thus providing a framework of analysis for Twitter practice and strategic direction for companies developing their use of Twitter to communicate with their followers on this social media platform. This study has four specific research objectives. The first objective is to examine the applicability of brand personality dimensions used in marketing research to online brand communities on Twitter. The second is to establish a connection between the congruence of offline and online brand personalities in building a successful social media brand community. Third, we test the moderating effect of product involvement in the effect of brand personality on brand community engagement. Lastly, we investigate the sentiment quality of consumer messages to the firms that succeed in communicating their brands' personalities on Twitter.

  • "Dokseoyeoga Do"(An Enjoyable Pleasure with Reading) is a work included in a collection book of both poems and works called as "Gyunggyo Myungseung Cheop"(Collections of Beautiful Scenary in the Suburb of Seoul) with a promise that a great painter Gyumjae Jung-Sun(謙齋 鄭敾) and his lifelong friend, Sacheon Lee Byung-Yeon(李秉淵) should hopefully exchange their poems and painted works. So far, general perspective of art history toward this work is either self-portrait of Gyumjae himself or genre painting of the aristocrat. The purpose of this study is to interpret in-depth meanings implied in this work with various considerations of plant elements appeared in this work. As a result of this study, We could draw newer and additional meanings beyond the existing perspectives of art history research categories, and the details can be summarized as following below. First of all, we could approach a new interpretation implying that Gyumjae and Sacheon hopefully wished their well-being, friendship, and reunion. Second, as a means of expressing this meaning, plant elements like old juniper(Juniperus chinensis L.), orchid(Orchidaceae), and peony(Paeonia lactiflora var. hortensis) were used. Third, each plant element can be literally seen as an icon implying message that Gyumjae desired to give to Sacheon. To be more detailed, experience and greenness of old juniper imply well-being of two people, and orchid implies fragrant friendship, and peony implies the feeling that Gyumjae hopefully desired to make a reunion with a parted friend. The significance of this study is that throughout old paintings, we could observe substantial examples of recognizing the meanings of plant elements in a category of traditional landscaping and utilizing them. Moreover, adding various point-of-views of many professional categories like Korean Landscaping history in the traditional painting research, we could also recognize the potentials for making rich interpretation toward implicated meanings of old paintings.

  • The purpose of this article is figuring out the modern understanding of SimChong Jeon's narrative and its storytelling strategy in the movie (2014). In the movie, there are three steps which are based on the temporal flow of narrative. shows the web-like structure of desire especially by focusing on the male character Sim Hakkyu. The relationship among characters in is gradually broken because of the desire. Moreover, the desire pushes Sim Chong who is Sim Hakkyu's daughter into the sacrifice. This part seems similar with the narrative of SimChong-Jeon which has been transmitted since 18~19 century in Choson dynasty. However, also tells a different story which describes the progress of Sim Hakkyu's seeking the real relationship filled with love. This difference is able to make people read with the 'stroytelling' point of view. All the lack or problem in is closely related to the desire of Sim Hakkyu. His narrative is something different from the typical story of SimChong-Jeon. A new narrative of Sim Hakkyu is not Sim Chong centered story but rather the anti of it. 'The other narrative' in seems social practice of storytelling in order to break down the preconception of SimChong-jeon called 'cannon'. This is the storytelling strategy of and it suggests the another way of creating new narrative which is based on the classical cannon.

An Interdisciplinary Approach to the Human/Posthuman Discourses Emerging From Cybernetics and Artificial Intelligence Technology (4차 산업혁명 시대의 사이버네틱스와 휴먼·포스트휴먼에 관한 인문학적 지평 연구)

  • This paper aims at providing a critical view over the cybernetics theory especially of first generation on which the artificial intelligence heavily depends nowadays. There has been a commonly accepted thought that the conception of artificial intelligence could not has been possible without being influenced by N. Wiener's cybernetic feedback based information system. Despite the founder of contemporary cybernetics' ethical concerns in order to avoid an increasing entropy phenomena(social violence, economic misery, wars) produced through a negative dynamics of the western modernity regarded as the most advanced form of humanism. In this civilizationally changing atmosphere, the newly born cybernetic technology was thus firmly believed as an antidote to these vices deeply rooted in humanism itself. But cybernetics has been turned out to be a self-organizing, self-controlling mechanical system that entails the possibility of telegraphing human brain (which are transformed into patterns) through the uploading of human brain neurons digitalized by the artificial intelligence embedded into computing technology. On this background emerges posthuman (or posthumanism) movement of which concepts have been theorized mainly by its ardent apostles like N. K. Hayles, Neil Bedington, Laurent Alexandre, Donna J. Haraway. The converging of NBIC Technologies leading to the opening of a much more digitalizing society has served as a catalyst to promote the posthuman representations and different narratives especially in the contemporary visual arts as well as in the study of humanities including philosophy and fictional literature. Once Bruno Latour wrote "Modernity is often defined in terms of humanism, either as a way of saluting the birth of 'man' or as a way of announcing his death. But this habit is itself modern, because it remains asymmetrical. It overlooks the simultaneous birth of 'nonhumaniy' - things, or objects, or beasts, - and the equally strange beginning of a crossed-out God, relegated to the sidelines."4) These highly suggestive ideas enable us to better understand what kind of human beings would emerge following the dazzlingly accelerating advancement of artificial intelligence technology. We wonder whether or not this newly born humankind would become essentially Homo Artificialis as a neuronal man stripping off his biological apparatus. However due to this unprecedented situation humans should deal with enormous challenges involving ethical, metaphysical, existential implications on their life.
