Visual Representation Competence Taxonomy (VRC-T) was developed in previous study(Yoon, 2018) to provide a framework conducive to assess visual representation competence and to devise appropriate educational activities for it. This study is an extension of the previous study. It aimed to explore the usefulness of VRC-T and revise it by analyzing the patterns of visual representation use in science lessons. The researcher collected lesson plans on shadow principle from 11 pre-service and 13 in-service elementary teachers and conducted individual interviews regarding what visual representations they considered and how they tried to use them in science lessons. VRC-T was used as an analytical framework to examine the types and cognitive processes of visual representations. As a result, new categories were added and the revised VRC-T was completed (VRC-TR). It was also found that both pre- and in-service teachers mainly focused on 'interpreting' the 'descriptive representation' while designing their lesson plans. Additionally, in-service teachers showed more limited use of visual representations compared to pre-service teachers. In-service teachers largely relied on the national science textbooks, while pre-service teachers reflected their own learning experiences in their teacher-training program. These results showed that teachers' use of visual representations heavily relied on their prior learning and teaching experiences. The VRC-TR presented in this study and examples of class activities in each category can be helpful for teachers and researchers who want to use visual representations more effectively.

This paper presents a framework for observable behavior that can be used as a basis for user modeling, and it reports the results of a pair of user studies that examine the joint utility of two specific behaviors. User models can be constructed by hand, or they can be teamed automatically based on feedback provided by the user about the relevance of documents that they have examined. By observing user behavior, it is possible to obtain implicit feedback without requiring explicit relevance judgments. Four broad categories of potentially observable behavior are identified : examine, retain, reference, and annotate, and examples of specific behaviors within a category are further subdivided based on the natural scope of information objects being manipulated . segment object, or class. Previous studies using Internet discussion groups (USENET news) have shown reading time to be a useful source of implicit feedback for predicting a user's preferences. The experiments reported in this paper extend that work to academic and professional journal articles and abstracts, and explore the relationship between printing behavior and reading time. Two user studies were conducted in which undergraduate students examined articles or abstracts from the telecommunications or pharmaceutical literature. The results showed that reading time can be used to predict the user's assessment of relevance, that the mean reading time for journal articles and technical abstracts is longer than has been reported for USENET news documents, and that printing events provide additional useful evidence about relevance beyond that which can be inferred from reading time. The paper concludes with a brief discussion of the implications of the reported results.

In this paper, we introduce and investigate a new category of rule-based fuzzy inference system based on Information Granulation(IG). The proposed rule-based fuzzy modeling implements system structure and parameter identification in the efficient form of “If..., then...” statements, and exploits the theory of system optimization and fuzzy implication rules. The form of the fuzzy rules comes with three types of fuzzy inferences: a simplified one that involves conclusions that are fixed numeric values, a linear one where the conclusion part is viewed as a linear function of inputs, and a regression polynomial one as the extended type of the linear one. By the nature of the rule-based fuzzy systems, these fuzzy models are geared toward capturing relationships between information granules. The form of the information granules themselves becomes an important design features of the fuzzy model. Information granulation with the aid of HCM(Hard C-Means) clustering algorithm hell)s determine the initial parameters of rule-based fuzzy model such as the initial apexes of the membership functions and the initial values of polynomial function being used in the Premise and consequence Part of the fuzzy rules. And then the initial Parameters are tuned (adjusted) effectively with the aid of the improved complex method(ICM) and the standard least square method(LSM). In the sequel, the ICM and LSM lead to fine-tuning of the parameters of premise membership functions and consequent polynomial functions in the rules of fuzzy model. An aggregate objective function with a weighting factor is proposed in order to achieve a balance between performance of the fuzzy model. Numerical examples are included to evaluate the performance of the proposed model. They are also contrasted with the performance of the fuzzy models existing in the literature.

As Korea's representative medical text, "Donguibogam" reveals Korean Medicine's unique perspective on the human body. The text also contains abundant resources related to skin, leading to diverse researches on the subject today. In this paper, authors tried to elicit values of "Donguibogam" in the general cosmetics field, through literature review. First, prescriptions related to main functions of modern cosmetics (anti-aging, whitening, and moisturizing) were classified. In relation to anti-aging, concepts such as 返老 (reversing aging), 還童 (to become young again), 皺 (wrinkle), and 皮急 (tense skin) were extracted and 69 examples of treatments were introduced. For whitening care, 41 treatments were mentioned on hyper-pigmentation and general complexion. Concepts related to moisturizing included expressions such as 潤肌膚 (hydration of skin) and 光澤 (glow), induced by 48 treatment prescriptions. Second, cosmetics related prescriptions were classified according to the application methods of modern cosmetics. 78 prescriptions of cleansing category included washing-off local area with herbal liquid, bathing, washing-off after steaming, and soaking the body in the herbal liquid. Total of 308 topical application prescriptions covered the conditions of various skin inflammations, scalp illnesses, and etc. In conclusion, this research examines the value of "Donguibogam" as a useful of skincare. Further studies are expected to extend our understanding of the field.

The purpose of this research is to suggest diverse directions for eco-friendly knit designing through analyzing the characteristics of Stella McCartney's knit designs. The first stage of the research was to explore the characteristics of eco-friendly fashion design based on literature review. The next stage was to categorize the characteristics of eco-friendly design found in Stella McCartney' knit fashion based on the precedent analysis. The data collected showed 274 examples from 40 Stella McCartney collections, including Spring, Resort, Pre-Fall, and Fall Ready-to-wear collections between 2013 and 2022. All information was collected using www.vogue.com. As a result, the characteristics of Stella McCartney's knit design were classified into four directopms: 1) Perpetual Naturalism, 2) Cultural Complexity, 3) Practical Functionality, and 4) Subcultural Reproducibility. The first characteristic, 'Perpetual Naturalism' values the continuous symbiosis between animals and human beings, thereby protecting global environmental value. Stella McCartney's knit design continuously showed a longing for nature's beauty through fashion design, which allowed people to enjoy the meaning of symbiosis between human beings and animals. Second, 'Cultural Complexity' is the characteristic that appears in Stella McCartney's knit fashion design when collaborating with various artists and/or mixing traditional knit motives inspired by traditional cultures and retro moods. Third, 'Practical Functionality' is the design characterisitic that allows items to be worn for a long time as it is comfortable, simple, and practical. Stella McCartney's knit designs pursue easy-to-wear designs that are comfortable and have practical designs with simple details. Lastly, 'Subcultural Reproducibility' showed in Stella McCartney's knit designs reflect Hippie culture, which pursued a rejection of conventional values, and promoted sustainable energy. This culture peaked in the 1960s and 1970s, when 'Beatles' were mainly working. Additionally, retro styled knit designs inspired by other various music genres from the 1980s and 1990s appeared in this category as well.

This research interprets the unique hybridity of the pavilion architecture in the Joseon Dynasty, in which the name and form do not match and the rooms and floors are combined in various ways, through the Confucian architectural prototype Muijeongsa(武夷精舍) built by Zhu Xi(朱熹). The architectural representation of Muijeongsa, developed against the background of the mid-Joseon period of active pavilion management by Sarim(士林) groups, the spread of ondols due to the Little Ice Age, and an architectural culture following the footsteps of the Zhu Xi is likely to have influenced the perception and practice of pavilion architecture. In this research, by examining and analyzing the contents of the Muijeongsa Japyeongbyeongseo(武夷精舍雜詠幷序) containing the architectural composition of Muijeongsa, it was confirmed that different types of spaces such as Dang(堂), Jeong(亭), Jae(齋), and Gwan(館) are integrated into Muijeongsa. Based on this, the main examples of the architecture of Jeongsa in the mid-Joseon Dynasty were reinterpreted into four types from the perspective of the combination of Dang and Jeong, and the junction of Jeong and Jeongsa. Dang and Jeong were either juxtaposed as separate buildings or implemented with a relationship of inclusion within one building. And the concept of Jeong, which was considered secondary to Dang, was used as a category that was replaced with the Jeongsa itself. Lastly, the name 'Jeongsa' was used, but the location had a strong character of 'Jeong', and the architectural form adhered to the form of 'Dang', thereby exquisitely reconstructing the composition of Muijeongsa as a single building.

Purpose: Some of the properties of the prosodic phrasing and some acoustic and phonological effects of contrastive focus on the tonal pattern of Seoul Korean is explored based on a brief experiment of analyzing the fundamental frequency(=FO) contour of the speech of the author. Data Base and Analysis Procedures: The examples were chosen to contain mostly nasal and liquid consonants, since it is difficult to track down the formants in stops and fricatives during their corresponding consonantal intervals and stops may yield an effect of unwanted increase in the FO value due to their burst into the following vowel. All examples were recorded three times and the spectrum of the most stable repetition was generated, from which the FO contour of each sentence was obtained, the peaks with a value higher than 250Hz being interpreted as a high tone (=H). The result is then discussed within the prosodic hierarchy framework of Selkirk (1986) and compared with the tonal pattern of the Northern Kyungsang dialect of Korean reported in Kenstowicz & Sohn (1996). Prosodic Phrasing: In N.K. Korean, H never appears both on the object and on the verb in a neutral sentence, which indicates the object and the verb form a single Phonological Phrase ($={\phi}$), given that there is only one pitch peak for each $={\phi}$. However, Seoul Korean shows that both the object and the verb have H of their own, indicating that they are not contained in one $={\phi}$. This violates the Optimality constraint of Wrap-XP (=Enclose a lexical head and its arguments in one $={\phi}$), while N.K. Korean obeys the constraint by grouping a VP in a single $={\phi}$. This asymmetry can be resolved through a constraint that favors the separate grouping of each lexical category and is ranked higher than Wrap-XP in Seoul Korean but vice versa in N.K. Korean; $Align-x^{lex}$ (=Align the left edge of a lexical category with that of a $={\phi}$). (1) nuna-ka manll-ll mEk-nIn-ta ('sister-NOM garlic-ACC eat-PRES-DECL') a. (LLH) (LLH) (HLL) ----Seoul Korean b. (LLH) (LLL LHL) ----N.K. Korean Focus and Phrasing: Two major effects of contrastive focus on phonological phrasing are found in Seoul Korean: (a) the peak of an Intonatioanl Phrase (=IP) falls on the focused element; and (b) focus has the effect of deleting all the following prosodic structures. A focused element always attracts the peak of IP, showing an increase of approximately 30Hz compared with the peak of a non-focused IP. When a subject is focused, no H appears either on the object or on the verb and a focused object is never followed by a verb with H. The post-focus deletion of prosodic boundaries is forced through the interaction of StressFocus (=If F is a focus and DF is its semantic domain, the highest prominence in DF will be within F) and Rightmost-IP (=The peak of an IP projects from the rightmost $={\phi}$). First Stress-F requires the peak of IP to fall on the focused element. Then to avoid violating Rightmost-IP, all the boundaries after the focused element should delete, minimizing the number of $={\phi}$'s intervening from the right edge of IP. (2) (omitted) Conclusion: In general, there seems to be no direct alignment constraints between the syntactically focused element and the edge of $={\phi}$ determined in phonology; all the alignment effects come from a single requirement that the peak of IP projects from the rightmost $={\phi}$ as proposed in Truckenbrodt (1995).

The purpose of this study is to identify potential semantic landscape makeup of "the Forty Eight Poems of Soswaewon" according to Yin-Yang and Five Elements Principle(陰陽五行論). that speculation system between human's nature and cosmical universal order. Existing academic discussions made so far concerning this topic can be summed up as follows: 1. Among Yin-Yang-based landscape makeups of the Forty Eight Poems of Soswaewon, poetic writings for embodiment of interactions between nature and human behaviors focused on depicting dynamic aspects of a poetic narrator when he appreciates or explores hills and streams as of to live free from worldly cares. Primarily, many of those writings were created on the east and south primarily through assignment of yang. On the other hand, poetic writings for embodiment of nature and seasonal scenery - as static landscape makeup of yin - were often created on or near the north and west for many times. Those writings focusing on embodiment of nature and artificial scenery as a work are divided into two categories: One category refers to author Kim In-hu's expression of semantic landscape from seasonal scenery in nature. The other refers to his depiction of realistic garden images as they are. In the Forty Eight Poems of Soswaewon, the poetic writings show that author Kim focused on embodying seasonal scenery rather than expressing human behaviors. In addition, both Poem No. 1 and Poem No. 48(last poem; titled 'Jangwon Jeyeong') were created in a same place, which author Kim sought to understand the place as a space of beginning and end where yin and yang - i.e. the principle of natural cycle - are inherent. 2. According to construction about landscape in the Forty Eight Poems of Soswaewon on the basis of Ohaeng-ron (five natural element principle), it was found that tree(木) and fire(火) are typical examples of a world combined by emanation. First, many of poetic writings depicting the sentiments of tree focused on embodying seasonal scenery and were located in the place of Ogogmun(五曲門) area in the east, from overall perspective of Soswaewon. The content of these poems shows generation and curve / straightness in flexibility and simplicity. Many of poems depicting the sentiments of fire(火) focused on embodying human behaviors, and they were created in Aeyangdan area on the south of Soswaewon over which sun rises at noon. These poems are all on a status of side movement that is characterized by emanation and ascension which belong to attributes of yang. 3. With regard to Ohaeng-ron's interpretation about landscape in the Forty Eight Poems of Soswaewon, it was found that metal(金) and water(水) are typical examples of world combined by convergence. First, it was found that all of poems depicting sentiments of metal focused on embodying seasonal scenery, and were created in a bamboo grove area on the west from overall perspective of Soswaewon. They represent scenery of autumn among 4 seasons to symbolize faithfulness vested in a man of virtue(seonbi) with integrity and righteousness. Poems depicting sentiments of water were created in vicinity of Jewoldang on the north, possibly topmost of Soswaewon. They were divided into two categories: One category refers to poems embodying actions of welcoming the first full moon deep in the night after sunset, and the other refers to poems embodying natural scenery of snowscape. All of those poems focused on expressing any atmosphere of turning into yin via convergence. 4. With regard to Ohaeng-ron's interpretation of landscape in the Forty Eight Poems of Soswaewon, it was found that poems depicting sentiments of earth(土), a complex body of convergence and emanation, were created in vicinity of mountain stream around Gwangpunggak which is located in the center of Soswaewon. These poems focused on carrying actions of author Kim by way of natural phenomena and artificial scenery.

I analyze orange that is consistently used, even though not consciously, in the films whose function and meaning are clear. In detail, there are examples of color in films, psychological phenomena of colors expressed in posters and opening titles, color characteristics of clothes and costumes, and semiotic analysis of color names in film titles. (1) Fact and Truth; civilization and criticism. The film tries to tell the truth than the fact. It represents facts as it is, but it presupposes truth. This is a unique characteristic of media films. The truth of the fact is not important. The film tells the truth believing and wanting to show off. The film, which has inherent characteristics of the gap between fact and truth, represents nature and civilization. It carries nature as it is and criticizes the harm of civilization. Orange is nature and civilization. Realistic films such as Hong Sang Soo and Kim Ki Duk, fall into this category. For example, there are A Taxi Driver(2017) and I Can Speak(2017). (2) Virtual History; fake images and memories. In Hollywood SF genres like The Matrix(1999), orange was dealt with virtual reality. However, in Korean films they are replaced by historical dramas. The representation of history becomes a virtual reality. Films such as The Fortress(2017), Masquerade(2012), and Roaring Currents(2014) deal with virtual history. In these films, orange is a fake image and memory. (3) Light=color; Aura. The color and light of orange is aura. At sunrise and sunset, the orange of the incandescent light is almost similar to that of the artificial light. Orange of tungsten makes the real characters surrealistic and mysterious. For example, there are The City of Madness(2016), The Man from Nowhere(2010), and Coinlocker Girl(2014). (4) Fantasy; communication with other worlds. Orange is a sweet fantasy. In our daily life, we go to a supermarket, share a chat with friends in a coffee shop, and spend time in front of a television. Orange makes our life free and dreams. It is the communication between the former being and the other world. This can be found in the sexual fantasy scenes of all genres. For example, there are Sunny(2011), Welcome To Dongmakgol(2005), and 200 Pounds Beauty(2006).
