In this paper, we proposed an optimal design for determining the shape of a lifting lug freely by applying a multivariate function to the D-type lug, which is commonly used in shipyards. We derived the optimal aspect ratio of the lug through structural analysis and analyzed the safety and behavior of the lug aspect ratio. As a result, two types of final candidates, both lighter than the existing lug weight, were suitable for the ratio. They were found to have the greatest force at an angle of 45 degrees when a load of 100 tons was imposed. When the horizontal and vertical feature ratio of the lug was 1:3, it showed excellent results in terms of safety rates while maintaining weight reduction and functional aspects.

This study seeks to investigate K-fashion's external image by examining the trends in global media reporting. It applies Dynamic Topic Modeling (DTM), which captures the evolution of topics in a sequentially organized corpus of documents, and consists of text preprocessing, the determination of the number of topics, and a timeseries analysis of the probability distribution of words within topics. The data set comprised 551 online media articles on 'Korean fashion' or 'K-fashion' published on Google News between 2010 and 2021. The analysis identifies seven topics: 'brand look and style,' 'lifestyle,' 'traditional style,' 'Seoul Fashion Week (SFW) event,' 'model size,' 'K-pop,' and 'fashion market,' as well as annual topic proportion trends. It also explores annual word changes within the topic and indicates increasing and decreasing word patterns. In most topics, the probability distribution of the word 'brand' is confirmed to be on the increase, while 'digital,' 'platform,' and 'virtual' have been newly created in the 'SFW event' topic. Moreover, this study confirms the transition of each K-fashion topic over the past 12 years, along with various factors related to Hallyu content, traditional culture, government support, and digital technology innovation.

When used for broadcasting, multipurpose halls need to accommodate various types of programs such as speeches, Korean traditional music, musicals, pop music, and concerts. Therefore, multipurpose halls must meet a wide range of electric and architectural acoustic demands. However, there are few ways to alter acoustic environments for multipurpose halls, given these different demands. The current study investigates the effects of banners on acoustic environments in the presence of an acoustic shell or electric acoustic system. The results indicate that the installation of a 15% banner of wall area could vary the range of reverberation time ($T_{30}$) by 0.12 s, EDT (Early Decay Time) by 0.15 s, clarity of music ($C_{80}$) by 0.76 dB, and clarity of speech ($D_{50}$) by 6.43 % under different measurement circumstances. A computer simulation that enlarges the banner size to 40 % of the wall area varies the reverberation time from 0.11 s to 0.55 s depending on the room environment.

Recently, more focus is shift to imbalances in aggregate market supply and demand and an exhaustion of natural resources. In this situation, Electric arc furnace oxidizing slag (EAF slag) has high application possibility as aggregate for concrete due to similar property with general aggregate. However, it is inherent the problem which causes pop-out by free-CaO contained in slag In this study, we've got the plan to assure the chemical stability of EAF slag, and then experimentally tested the mechanical performance and durability for the fine aggregate used EAF slag. On this test result, we suggest the application plan. At the result of this study, it shows that EAF slag would reduce the surface defect such as pop-out due to natural aging for the fixed hour and adjustment the grain size of EAF slag. And mechanical performance and durability according to the replacement rate of concrete service, were revealed more than equal or equal compare to general aggregate. Hereafter, quality control must precede not to impede the beauty of concrete surface as assure the safety for aging and processing. And, to establish the environmental resource recycling system for by-products of steel, it should be made development of various application and guideline of quality control for the EAF slag aggregate. Moreover, it must be constantly studied all kind of engineering performance and durability for related to this study.

This paper aims to develop a system for converting web contents to mobile contents that can be used on mobile devices. Since web contents generally consist of pop-up ad windows, a bunch of unnecessary images and useless links, it is difficult to efficiently display them on common mobile devices that have lower bandwidth and memory, as well as much smaller screen, than the online environment. It is also troublesome for mobile device users to directly access contents. Thus, there has been a great demand for a new method for extracting useful and adequate contents from web documents, and optimizing them for use on mobile phones, In the paper, a system based on WAP 2,0 and XHTML Basic, which is a content creation language adopted for WAP 2,0, has been suggested. The system is designed to convert web contents by using the conversion rules of the existing filtering method after making the size of web documents smaller. The adopted conversion rules use the XHTML Basic's module units so that modification and deletion can be carried out with ease. In addition, it has been defined in a XSL document written in XSLT to maintain the extensibility of conversion and the validity of documents, In order to allow it to efficiently work together with WAP l.X's legacy services, the system has been built in a way that can have modules, which analyze information about CC/PP profiles and mobile device headers.

The purpose of this study is to examine the value of grotesque fashion and to predict the future fashion trend. The grotesque originates the formative art. It emerges towards of a century or transitional period in most case. In particular, it was used as the expressive method of an individual's inside and a satire on society through the work of artists in the Middle Age, the renaissance, the sym-bolism, the dadaism, the surrealism, the pop art, the technology art, and the post-modernism, etc. The grotesque in fashion is represented in the work of avant-garde fashion designers who lead the high fashion. The grotesque fashion which was combined with an image of non-formality, non-rationality, an absurdity and reality. It has been begun shape of female dress in the renaissance. Afterwards, it was represented in extremely exaggerated and distorted pop art, hippies' fashion in the 1960's. In the 1970's, it was reflected in genderless rock star and destructive punk fashion. It was also represented in the androgynous fashion which was combined with both sexes, the goth/gothic fashion which was expressed with a realistic and fanciful shape and the tattoo of skin-head in the 1980's. In the 1990's, the grungy look which was dirty and the cyber punk fashion. In general, it was also expressed by the avant-garde fashion designers. To sum up, a grotesque fashion which is expressed by experimental designers is classified into four shapes. 1, Union of some extraneous is expressed as different kinds of fashion theme, such as abnormality of texture, uses of surrealistic elements and chaos of sex. Although it appears that the abnormal union of grotesque has only discord and collision, it also shows a feeling of freedom for the tension. 2. Introduction of real and fanciful image is expressed as a cyborg, realistic description of disgusting animal skin and aggressive shape. Especially, it is worth while to notice Tierre Mugler and Alexander Macqueen's work which expressed the shape of mingling human of Middle Age. 3. distortion or exaggeration is expressed as an unformed shape, the exaggeration of a clothing size, the abnormal exaggeration of human body and the ignorance of clothing form. 4. Introduction of a disgusting image is expressed as an extremity of reality, motifs of death, clothing material of disgusting hair and the ostentation of sex. Motto which leads modern fashion is something new and shocking. The grotesque fashion is an expression of eagerness for something new. It often show something ironic in the form of humor which is embedded in an abnormal and shocking pattern. The grotesque fashion is represented as an extreme beauty. It will stand as an important element of the future fashion and as a particular style with the change and fluidity.

Korea's entertainment industry laid its foundation in the early 2000s when global popularity of South Korean soap operas increased in Japan. K-pop has been recently leading the popularity in China. However, many Korean entertainment businesses are dying out. This study reviews factors influencing business survival for 42 chosen corporations listed in the Korea Stock Exchange based on organizational ecology. When all of the variables are analyzed at the same time, long period of public offering and high wages and global sales ratio positively affect business survival. When the individual variables are separately analyzed, long period of public offering and CEO incumbency and high wages and global sales ratio positively affect business survival. Meanwhile, size of businesses do not affect the survival. The results of this study imply that policies to help businesses list an entertainment corporation in the Korea Stock Exchange, increase sales and reciprocity with other culture are needed. Laws and institutions for evaluating intangible asset value should be improved. The results also suggest that a corporation should carefully consider change of CEO and make the best use of the popularity of Korean culture to increase global sales and pay competitive wages to attract professionals.

Objectives: The concentration distributions of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), dioxin-like polychlorinated biphenlys (dl-PCBs), and polycyclic aromatic hydrocarbons (PAHs) in fine particles were investigated to provide basic data on POP behavior and composition analysis. Methods: The concentrations of PCDD/Fs, dl-PCBs, and PAHs by particle size were evaluated for TSP, PM₁₀, and PM_2.5. Also, fine dust component analysis and factor analysis were performed to identify the source of PCDD/Fs. Results: The particle size distribution was found to account for 24.3% of >10 ㎛, 14.5% of 2.5-10 ㎛, and 61.2% of <2.5 ㎛. The average contributions of coarse particles (>2.5 ㎛) and fine particles (<2.5 ㎛) were PCDD/Fs 67%, dl-PCBs 66%, benzo (a) pyrene 83% and PAHs 84%, and the contributions of fine particles (<2.5 ㎛) were higher than coarse particles (>2.5 ㎛). However, the contributions of coarse particles increased in April to September with higher temperatures, while those of fine particles increased in February to March with lower temperatures. Conclusions: Low chlorinated (4Cl-5Cl) PCDD/Fs were more adsorbed compared to coarse particles due to the influence of pollutant migration from particulate to gas phase according to temperature rise, whereas high chlorinated (6Cl-8Cl) PCDD/Fs were more adsorbed compared to fine particles. PCDD/Fs sources were assessed to be major sources of emissions, such as incineration facilities and/or open burning.

According as the fashion at the latter half part of the 20th century is diversified and made into high-class gradually, it is demanding the individuality of each one. Especially, since the beginning of 1980s, fashion came to represent the restoration mood in a modern style because of the popularization of post-modernism. And with this, it came to result in the reappearance of minimalism which was one of anti-culture in 1960s. In this study, this researcher grasped the appearance background, concept and structural concept of minimalism, and tried to study the influence that he minimalism had on fashion in the flow of fashion over the first half period of the 20th century. Minimalism is the fine art trend of American characteristic which quicked by the meeting of European culture and American culture, according as the new avant-grade art of Europe moved to America after World War II Minimalism which appeared, refusing the mechanisation, industrialization and mass production of America and the falsehood of consciousness and sensitivity under existing system remained obscure by the pop art which is the commercial fine art of same period, but it came to expand the domain of work possibility of modern fine art, and it became the basis of appearance of post-modernism. Minimalism has 4 kinds of structural features which are nonside nature, repetitiousness and environment nature with 3 dimensional feature which is issue nature. Minimalism is appearing in the exfcellent and future-oriented fashon of Andre Kureju t the time of 1960 well. Then science revolution and minimalism aroused the mini-revolution, and they made the compact radio in electric home appliances and the miniskirt in fashion appear. The features of minimal fashion as Retro '60' which appeared in the decedent mood with the 21st century just before on are as follows: First, the are the pursuit of concise plastic line. Second, it is the use of high tech material Third, the miniaturization in size amy be enumerated. Minimal fashion will appear s the positive confrontation from of mankind as the optimistic viewpoint about feature in the situation hat environment was destroyed and the resources were exhausted.
