Purpose - This is an exploratory study that aims to apply text mining techniques, which computationally extracts words from the large-scale text data, to legal documents to quantify trade claim contents and enables statistical analysis. Design/methodology - This is designed to verify the validity of the application of text mining techniques as a quantitative methodology for trade claim studies, that have relied mainly on a qualitative approach. The subjects are 81 cases of arbitration and court judgments from China published on the website of the UNCITRAL where the CISG was applied. Validation is performed by comparing the manually analyzed result with the automatically analyzed result. The manual analysis result is the cluster analysis wherein the researcher reads and codes the case. The automatic analysis result is an analysis applying text mining techniques to the result of the cluster analysis. Topic modeling and semantic network analysis are applied for the statistical approach. Findings - Results show that the results of cluster analysis and text mining results are consistent with each other and the internal validity is confirmed. And the degree centrality of words that play a key role in the topic is high as the between centrality of words that are useful for grasping the topic and the eigenvector centrality of the important words in the topic is high. This indicates that text mining techniques can be applied to research on content analysis of trade claims for statistical analysis. Originality/value - Firstly, the validity of the text mining technique in the study of trade claim cases is confirmed. Prior studies on trade claims have relied on traditional approach. Secondly, this study has an originality in that it is an attempt to quantitatively study the trade claim cases, whereas prior trade claim cases were mainly studied via qualitative methods. Lastly, this study shows that the use of the text mining can lower the barrier for acquiring information from a large amount of digitalized text.

The objective of this study was to explore the symbolism associated with phoenix patterns in China and the temporal aesthetic characteristics of these patterns found in Dunhuang Mogao Grottoes. The study involved collecting examples of clothing designs featuring phoenix patterns from China Fashion Week and the Vogue website, spanning from spring and summer of 2016 to fall and winter of 2022. After collecting and organizing these examples, representative cases were selected for analysis. The objective was to identify effective techniques for incorporating phoenix patterns within the context of Dunhuang Mogao Grottoes and provided insights for future clothing design and textile pattern design research. Phoenix patterns boasted a lengthy history and were laden with symbolic meaning. Early renditions of phoenix patterns found at Mogao Grottoes in Dunhuang were relatively simplistic in design, mainly employing elements like rhythm, coordination, balance and symmetry to convey a sense of nature and gravity. Over time, these patterns evolved under the influence of the prevailing cultural backdrop, employing repeated emphasis to portray notions of abundance and tenacity. Furthermore, regarding the use of phoenix patterns in clothing, there were four prevalent expression techniques: embroidery, beading, printing, and knitting. Traditional techniques like embroidery and beadwork often prioritized aesthetic features like coordination, emphasis, and symmetry, thereby showcasing the opulent characteristics of phoenix patterns. On the other hand, printing and knitting techniques used a single phoenix pattern or a modified version to simplify designs by emphasizing or repeating aesthetic characteristics while adhering to a modern artistic approach.

Due to hazardous working environments at complex, unstructured, and dynamic construction sites, workers frequently face potential safety and health risks throughout the construction process. In this regard, addressing safety challenges remains one of the top priorities. Construction workers' ability to identify and assess risks is acquired through training, which is one of the primary key factors to determine their safety and wellbeing in hazardous working environments. As such, safety managers constantly focus on the effectiveness of the training materials provided to the workers. However, the construction workers are considerably at greater risk of injuries and fatalities compared to the workers in other industries. In this regard, further studies are required to build up a body of knowledge on the conventional safety training approaches as well as their evaluation techniques in order to boost up the adoption by the practitioners in a widespread manner. This paper provides a systematic review of the current safety training approaches and the various techniques for measuring their effectiveness. The attributes of the current safety training methods for construction workers and their evaluation techniques are identified and analyzed. Results indicated that: 1) immersive environment-based training methods are effective than the traditional safety training methods; 2) this effectiveness can be empirically supported by evaluation strategies, but the current techniques are subjective, intrusive, and error-prone. This research offers fresh opportunities to investigate the training strategies by objectively monitoring the physiological responses of construction crews. The results of this study can be used by researchers and practitioners to identify and determine optimal safety training programs that could potentially become ubiquitous in the construction industry.

Traditional familism and family value is known as the value that most Koreans share with. Strong family solidarity and family-centered perception among Koreans influences other social values and ideology. Under the family value, caring for family members is family responsibility instead of government responsibility. Previous studies argued that the family value played a role to impede the development of family policy in Korea. The aim of this study was to explore a relation between the family value and the needs for care-support family policy. This study investigated how the family value were related to the specific needs for care-support family policy. The data were drawn from the Seoul Families Survey conducted on 2006 by Seoul Women and Family Foundation. The survey data consisted of 2,500 married males and females living in Seoul. The statistical techniques used for analysis were frequencies, means, t-test, ANOVA, crosstabs, multiple regression models, and multinomial logit models. The major findings of this study were as followings. First, while the traditional familism appeared to be held at a certain level, the general attitudes towards cohabitation, divorce, and single-parent family seemed to be less traditional. Second, the familism was found to be partly associated with the needs for the care-support family policy. The respondents who had less traditional value on arriage and child-rearing showed the higher level of needs for daycare center. This finding implied that nontraditional attitudes were related to the needs for an alternative care service such as caring through facilities rather than to the needs for supportive or complementary services. Lastly, the respondents who had higher level of traditional familism showed a higher preference for direct economic service (supportive service) than for other types of service in child care. And the less traditional their attitudes towards marriage and child-rearing, the more likely they are to prefer flexible child care services and programs to other types of child care services. These results implied that the family value was partly influential to family policy. However, it is worthy to note that the family value was related to family policy preference rather than to family policy needs. In other words, traditional family value appeared to influence the types of family policy rather than the level of needs for family policy.

This study investigated the recognition of Koreanesss, preference factors and the difference of recognition from adjacent Chinese and Japanese gardens for foreign visitors of Seoul gardens, a Korean traditional garden located within the Marzahn garden in Berlin, Germany. Overall, the Chinese garden and the Japanese garden were better known to most visitors than the Seoul garden due to their earlier construction. The awareness of the specialty to the Korean garden was at an average level indicating most visitors did not recognize the difference among the traditional gardens constructed from other countries. These less awareness on the Korean garden was because the traditional gardens of the three countries are located adjacent to the park in a continuous landscape with similar plant species created through natural planting techniques. This means the Korean garden is required for considering diversity and representativeness of planting species, uniqueness in space composition and recognition of Korean oriental garden culture in an initial design project stage. Visitors without prior information has better understanding on Korean garden and higher revisit intention resulting in increasing publicity and understanding of Korean traditional garden. Among the preference factors representing Koreaness of the Seoul gardens, the waterfall, stream, pavilion and natural stone within the water landscape were visitors favorite interests due to design concept with a representative Korean stream scenery of Dokrack-dang and Byeolseo garden resulting in differences from the landscape displaying technique for other oriental gardens. These stylistic differences in the dominant landscaping of garden architecture from surrounding the physical environments, the garden displaying technique derived from Korean natural landscape can be recognized as an unique garden element for foreign visitors.

Since seagrasses are highly productive and provide a source of organic carbon for a wide variety of marine organisms in coastal and estuarine ecosystem, accurate assessment of seagrass production is critical to understand the functions and values of seagrasses in these ecosystems. Zieman's leaf marking technique has been mostly used to estimate seagrass leaf production rates. However, inherent problems on the traditional leaf marking technique have been discussed by the several researchers, and these problems can cause underestimation of seagrass production. To develop an accurate and reliable assessing method for seagrass production, production rates of eelgrass, Zostera marina in three bay systems on the south coast of the Korean peninsula were estimated using the conventional leaf marking technique and the plastochrone method. The plastochrone method has been recently suggested as an effective method for reliable assessments of seagrass production. In the present study, leaf production rates estimated by the plastochrone method were significantly higher than the rates derived from the traditional leaf marking technique. Annual eelgrass leaf production assessed using the leaf marking technique was about 65 to 89% of the estimated production using the plastochrone method. The differences in annual productions between assessment techniques imply that the conventional leaf marking technique significantly underestimated eelgrass leaf production. Total eelgrass productions estimated using the plastochrone method in the present study sites were about 600 to 806 g DW $m^{-2} y^{-l}$, and below-ground production accounted for about 20 to 23% of the total production. The plastochrone method was suggested to be an effective and accurate assessing method for eelgrass production.

The purpose of this thesis is to discuss corsets that represent an undergarment that later became a popular outerwear. It discusses its forms and distinct characteristics to help create a unique fashion design and its execution. The scope of this study is limited to works from the 1990s to the present, and the materials for the literatures and exploratory study are fashion-related portfolios and the domestic and foreign fashion magazines. The results of this study are summarized as follows: The standard look of corsets in modern fashion can be classified into styles of glamour, revival, and dismantle. The materials used vary from traditional fabrics such as satin or lace to newly developed materials such as metal or glass. Its presentation can also differ in that it may be used as an accessory with additional details, as an outerwear, as an extra decorative layer, or as a revealing innerwear by open outerwear. Characteristics of these various looks of corsets are; first, it redefines the revival of the traditional corsets through introduction of its historic elements and its compromise. Second, glamorous and feminine images are maximized through drastic and direct exposure by using tight lacing, a waist nipper or garter belts that emphasize a woman's curve. Third, it represents borderless dismantlement through experimental and irregular images using unconventional materials, new execution techniques, or alteration from the standard forms.

Recently more than ever, interest in Korean tradition has been on the increase, with an active movement to follow tradition. There are various merits for expression with the use of Korean paper as a clothing material. The purpose of this study was to assess the aesthetic characteristics of men's shirts fashioned using Korean paper (Hanji). The following conclusions were obtained from an analysis of the aesthetic characteristics of Hanji shirts. First, Hanji has a peculiar texture, with natural characteristics due to the direct use of naturally handcrafted materials. Hanji shirts have the natural beauty of pure Hanji, without artificial treatment or other subsidiary materials, with the exception of thread. Secondly, Hanji shirts with decorative details and trimmings, such as frills, pin tuck, embroidery and spangles, express an ornamental beauty. Thirdly, Hanji shirts with frills or a fringe have real movement when worn and spangles give the illusion of movement due to changes in color or twinkling caused by light giving the beauty of rhythmical motion. Fourthly, Hanji shirts produced using the application of various techniques, such as crumple, painting and dying, express artistic beauty. Fifthly, Hanji shirts can express traditional beauty, even if created whit modem designs, but using traditional materials.

Structural system identification (SSI) is an inverse problem of difficult solution. Currently, difficulties lie in the development of algorithms which can cater to large size problems. In this paper, a parameter estimation technique based on evolutionary strategy is presented to overcome some of the difficulties encountered in using the traditional system identification methods in terms of convergence. In this paper, a non-traditional form of system identification technique employing evolutionary algorithms is proposed. In order to improve the convergence characteristics, it is proposed to employ immune algorithms which are proved to be built with superior diversification mechanism than the conventional evolutionary algorithms and are being used for several practical complex optimisation problems. In order to reduce the number of design variables, domain decomposition methods are used, where the identification process of the entire structure is carried out in multiple stages rather than in single step. The domain decomposition based methods also help in limiting the number of sensors to be employed during dynamic testing of the structure to be identified, as the process of system identification is carried out in multiple stages. A fifteen storey framed structure, truss bridge and 40 m tall microwave tower are considered as a numerical examples to demonstrate the effectiveness of the domain decomposition based structural system identification technique using immune algorithm.

Magnetic disks have been used for decades in auxiliary storage devices of computer systems. In recent years, the use of NAND flash memory, which is called SSD, is increased as auxiliary storage devices. However, NAND flash memory, unlike traditional magnetic disks, necessarily performs the erase operation before the write operation in order to overwrite data and this leads to degrade the system lifetime and performance of overall NAND flash memory system. Moreover, NAND flash memory has the lower endurance, compared to traditional magnetic disks. To overcome this problem, this paper proposes EPET (Enhanced Prediction and Elapsed Time) wear leveling technique, which is especially efficient to portable devices. EPET wear leveling uses the advantage of PET (Prediction of Elapsed Time) wear leveling and solves long-term system failure time problem. Moreover, EPET wear leveling further improves space efficiency. In our experiments, EPET wear leveling prolonged the first bad time up to 328.9% and prolonged the system lifetime up to 305.9%, compared to other techniques.
