In contemporary art, soft materials are used in various forms and ways as a medium expressing contingency beyond a simple nature of materials. In the late 1960's, the appearance of soft sculpture as a refusal of the stereotyped 'Erection' characteristic of traditional sculpture served as an opportunity for more attention to soft materials. Fashion is the reflection of age, and the mirror of society, culture and arts. In other words, soft sculpture and fashion are artistic behaviors in the same context, which have neither been fixed nor erected. This study finds its significance in analyzing correlation between soft sculpture and fashion, and the importance of contingency as artistic expression means in this age when boundaries between genres are obscure, and artistic values are given to fashion. By doing so, it aims to present the direction toward which fashion should face in the future, establishing a new aesthetic consciousness with which more creative and various expressions are available in fashion as well. This study presented as its theoretical background the concept of soft sculpture affected by Marcel Duchamp among representative examples of the contingency that started to appear in art starting in the early 20th century. It also analyzed the soft sculpture appeared in 1960s and the expression methods and features of contingency appeared in fashion after late 1990s through a new approach of piling up, hanging up, and tying, three categories classified by Maurice $Fr{\acute{e}}churet$. Common features of the contingency expressed in soft sculpture and fashion were derived in the analysis, which are intensive effects of energy, values given to physical properties themselves, and esthetics of anti-form.

In Webspace, mining traversal patterns is to understand user's path traversal patterns. On this mining, it has a unique characteristic which objects (for example, URLs) may be visited due to their positions rather than contents, because users move to other objects according to providing information services. As a consequence, it becomes very complex to extract meaningful information from these data. Recently discovering traversal patterns has been an important problem in data mining because there has been an increasing amount of research activity on various aspects of improving the quality of information services. This paper presents a Dynamic Link Recommendation (DLR) algorithm that recommends link sets on a Web site through mining frequent traversal patterns. It can be employed to any Web site with massive amounts of data. Our experimentation with two real Weblog data clearly validate that our method outperforms traditional method.

The purpose of this study is to analyse the effects of teachers'personal background (academic, education career) and institutional characteristic factors(founded facility type, class size, and curriculum organization type) on the quality of the classroom in early childhood education and care(ECEC) fields. This study is to explore the conditions for improving the quality of ECEC, looking back on a traditional paradigm focused on teacher education and qualifications. The hierarchical regression analysis was conducted through a survey as a research method. The results indicated that the effects of institutional characteristics were more influential than teachers' education on classroom quality. Public kindergartens and child care centers were reported to have higher effects than the private ones on classroom quality. Based on these results, policy implications and future research plans were suggested in perspective of improving the publicness of ECEC services.

Integrated-Salmi can be suggested as a character of Da-po type Kong-po in Korea's traditional architecture. However, only few studies are made on this subject yet. This study is to investigate the integration process of Salmi through cases of certain Kong-po which have the same number of inner and outer Chul-mok and are also known to precede in time. The results of the study are like below. First, Integrated-Salmi is more dominant in inner and outer 3 Chul-mok Kong-po than in inner and outer 2 Chul-mok Kong-po. Second, While inner and outer 2 Chul-mok prevail in Yeong-nam region, inner and outer 3 Chul-mok prevail in Ho-nam region. Third, integrated Salmi of Inner and outer 3 Chul-mok, first appeared in internal Jusangpo to be carried over to internal Juganpo then eventually to outer Salmi. Fourth, the reason why integrated form precede in internal salmi of inner and outer 3 Chul-mok Kong-po is due to 2 main factors. First of which is the impact of integrated Boaji that developed in Da-po type since the early 16th century. The second factor is downward expansion of Cho-gak's Boaji which was adopted to cope with disorders made in structure of Chum-Cha, due to inner and outer 3 Chul-mok type buddhist temples' wide reconstruction throughout Jeolla region following the Japanese invasion of Korea in 1592. This study is to disclose the regularity of development process of Salmi's Cho-gak(草刻) which is a characteristic of Korea's Da-po type Kong-po.

"SaCheolNaMu" has been used as a Korean folk medicine for the jaundice, lumbago and uterine diseases. Although a crude drug related to this folk medicine is sold in traditional herbal market, the botanical origin of this drug has not been pharmacognostically confirmed yet. In this study, the morphological and anatomical characteristics of the stem of Euonymus species growing in Korea, i.e. Euonymus japonica and E. fortunei var. radicans were studied to clarify the botanical origin of "SaCheolNaMu". As a result, it was found that these two species could be discriminated by the morphological criteria such as the thickness of cuticles, the number of collenchyma cell layers, and the frequency of druse and resinous substance. According to these criteria, it was elucidated that the commercial folk medicine "SaCheolNaMu" was the stem of E. japonica. Meanwhile, HPLC-DAD analysis on the 70% ethanolic extracts of two species showed significantly different HPLC profiles each other. The molecular ions of three characteristic peaks shown in the chromatogram of two species were identified by ESI-MS, and their structures were estimated to be flavonol glycosides.

The influence of Japonism, which is the post-mid-$19^{th}$ century phenomenon of appreciating and preferring the Japanese style that manifested all across Western art, started to grow as a result of the active open-door policy of Japan at this time. As all areas of Japanese arts and culture, such as paintings, sculptures and theater plays, influenced Europe and America, this influence developed into a cultural phenomenon that was reflected even in fashion. The characteristic elements of the kimono first expanded from Paris and showed a similar silhouette to that of the traditional kimono in the early $20^{th}$ century, but towards the middle and the end of the century, kimono sleeves that were connected as one piece without a connecting seam line between the sleeve and bodice started to appear. The foundation of this research focuses on the design characteristics of kimono sleeves that can be seen in $20^{th}$-century fashion, and five varying kimono sleeve jackets and coats based on these formative characteristics were designed. Each design had a gusset design added, which improved the external and mobility problems inherent in kimono sleeve patterns, while at the same time serving as a proposal for new design element applications. Additionally, through various changes to and attempts at designs using the kimono sleeve as a limiting factor, new design possibilities were explored.

The nuclear reactor coupled with supercritical carbon dioxide (S-CO₂) Brayton cycle has good prospects in generation IV reactors. Turbomachineries (turbine and compressor) are important work equipment in circulatory system, whose performances are critical to the efficiency of the energy conversion system. However, the sharp variations of S-CO₂ thermophysical properties make turbomachinery performances more complex than that of traditional working fluids. Meanwhile, almost no systematic analysis has considered the effects of turbomachinery efficiency under different conditions. In this paper, an in-house code was developed to realize the geometric design and performance prediction of S-CO₂ turbomachinery, and was coupled with systematic code for Brayton cycle characteristics analysis. The models and methodology adopted in calculation code were validated by experimental data. The effects of recompressed fraction, pressure and temperature on S-CO₂ recompression Brayton cycle were studied based on detailed design of turbomachinery. The results demonstrate that the recompressed fraction affects the turbomachinery characteristic by changing the mass flow and effects the system performance eventually. By contrast, the turbomachinery efficiency is insensitive to variation in pressure and temperature due to almost constant mass flow. In addition, the S-CO₂ thermophysical properties and the position of minimum temperature difference are significant influential factors of cyclic performance.

Objectives Recently the fuzzy logic is widely used in the decision making, identification, pattern recognition, optimization in various fields. In this study, we propose the fuzzy logic as the objective method of distinguishing hot and cold, the basis of diagnosis in Korean medicine. Methods We developed fuzzy inference system to distinguish whether the subjects had hot or cold. The cold and hot questionnaire of Korean traditional university textbook, the pulse rate and the DITI value of face used in the system. These three kinds of information were defined as 'fuzzy sets,' and 54 fuzzy rules were established on the basis of clinical practitioners' knowledge. The fuzzy inference was performed by using the Mamdani's method. To evaluate the usefulness of the fuzzy inference system, 200 cases of data measured in the Woosuk university hospital of oriental medicine were used to compare the determining hot, normal, cold results obtained from the experts and from the proposed system. Results As a result, 100 cases of "cold", 54 cases of "normal", and 34 cases of "hot" were matched between the experts and the proposed system. This fuzzy system showed the conformity degree of 94%(${\kappa}=0.853$). Conclusions In this study, we could express the process of distinguishing hot-cold using the fuzzy logic for objectification and quantification of hot-cold identification. This is the first study that introduce a fuzzy logic for distinguish pattern identification. The degree of the heat characteristic of the patients inferred by this system could provide a more objective basis for diagnosing the hot-cold of patients.

With increase of internet users, usage frequency of e-mail card is growing up. In addition to advantage of delivering message in real-time, e-mail card contains words, animation and sound. So users can enjoy it's multiple characters. For these reasons, there is a shift in preference from traditional card to e-mail card especially in young age. In character portal sites sewing users with e-mail card it is regarded as useful media for character promotion. After bizarre rabbit 'Mashimaro' wins a great success as Flash animation, Flash card has been treated as an important media in character business. As the study on the aesthetic motive in Flash card, this thesis analyzes what is the meaning existing in characteristic expression of Flash card and proposes that the meaning is related to tension reduction from the viewpoint of entropy principle. We can summarize that contents of animation are based on striving toward simplicity and expressions of animation are based on catabolism. Both lead to pleasure of tension reduction. We can draw conclusion that pleasure of tension reduction becomes one of major factors of the aesthetic motive felt in Flash card.

According to information theory, non-orthogonal transmission can achieve the multiple-user channel capacity with an onion-peeling like successive interference cancellation (SIC) based detection followed by a capacity approaching channel code. However, in multiple antenna system, due to the unideal characteristic of the SIC detector, the residual interference propagated to the next detection stage will significantly degrade the detection performance of spatial data layers. To overcome this problem, we proposed a modified power-domain non-orthogonal multiple access (P-NOMA) scheme joint designed with space-time coding for multiple input multiple output (MIMO) NOMA system. First, with proper power allocation for each user, inter-user signals can be separated from each other for NOMA detection. Second, a well-designed quasi-orthogonal space-time block code (QO-STBC) was employed to facilitate the SIC-based MIMO detection of spatial data layers within each user. Last, we proposed an optimization algorithm to assign channel coding rates to balance the bit error rate (BER) performance of those spatial data layers for each user. Link-level performance simulation results demonstrate that the proposed time-space-power domain joint transmission scheme performs better than the traditional P-NOMA scheme. Furthermore, the proposed algorithm is of low complexity and easy to implement.
