Advances in 3D garment simulation technology contribute greatly to consumers becoming more immersed in movies and games by realistically expressing the garments the characters in the movie or game are wearing. The fashion industry has reached a point where it needs to maximize efficiency in production and distribution to go beyond time and space in order to compete on the global market. The processes of design and product development in the fashion industry require countless hours of work and consume vast resources in terms of materials and energy to repeat sample production and assessment. Therefore, the design and product development tools and techniques must aim to reduce the sample making process. Therefore, this study aims to study a case for comparing the real garment sample making process to the virtual garment sample making process. In this study, we have analysed the differences between the real and virtual garment making processes by choosing designated patterns. As we can see from the study results, the real and virtual garments generally are made through similar processes in manufacturing, while the time consumed for each shows great variation. In real garment making, scissoring and sewing require the greatest number of work hours, whereas in virtual garment making, most of the time was spent in the simulation process.

The paper describes results of a sensitivity study on an optimum mooring cost as a function of safety factor and allowable maximum offset of the offshore floating structure by finding the anchor leg component size and the declination angle. A harmony search (HS) based mooring optimization program was developed to conduct the study. This mooring optimization model was integrated with a frequency-domain global motion analysis program to assess both cost and design constraints of the mooring system. To find a trend of anchor leg system cost for the proposed sensitivity study, optimum costs after a certain number of improvisation were found and compared. For a case study a turret-moored FPSO with 3 ${\times}$ 3 anchor leg system was considered. To better guide search for the optimum cost, three different penalty functions were applied. The results show that the presented HS-based cost-optimum offshore mooring design tool can be used to find optimum mooring design values such as declination angle and horizontal end point separation as well as a cost-optimum mooring system in case either the allowable maximum offset or factor of safety varies.

This The main objective of the study is to examine success clues of the firm influenced by top manager(Masayoshi Sohn) who belongs to Korean-Japanese third generation diaspora. A company's management style depends greatly on the value of its top manager, who also affects success and failure of the firm. SOFTBANK's management style could be influenced by the identity and values of Masayoshi Sohn. The results of the study are as follows ; firstly, his firm remains born-global firm owing to his global value rooted from his de-ethnification and studying in America. Secondly, the firm has challenge spirit owing to his experience of overcoming discrimination and repression during childhood time. and his role model 'Ryoma". Thirdly, there is a roly poly spirit in his firm because he has overcome complex coming from Korean-Japanese third generation diaspora. Finally, his company has human-oriented management philosophy because he has influenced a lot form his grand mother, Won-Cho Lee who emphasized much on human-beings. His identity and values have infiltrated Softbank's management style, which has led to the success of the company. This study will provide you with different viewpoints on the study for Korean-Japanese third generation diaspora.

Many previous tall building fires demonstrate that despite code compliant construction fires often spread vertically and burn over multiple floors at the same time. The collapses of the WTC complex buildings in 9/11 as well as other partial collapses like the ones of the Windsor Tower in Madrid and of the Technical University of Delft building posed new questions on the stability of tall buildings in fire. These accidents have shown that local or global collapse is possible in multi-floor fires. In most of the previous work involving multi-floor fires all floors were assumed to be heated simultaneously although in reality fires travel from one floor to another. This paper extends previous research by focusing on the collapse mechanisms of tall buildings in fire and performs a parametric study using various travelling rates. The results of the study demonstrate that vertically travelling fires have beneficial impact in terms of the global structural response of tall buildings in comparison to simultaneous fires. Contrary to the beneficial effect of the travelling fires in terms of the global structural response, it was noticed that higher tensile forces were also present in the floors compared to simultaneous multi-floor case. Designers are therefore advised to consider simultaneous multi-floor fire as an upper bound scenario. However, a scenario where a travelling fire is used is also suggested to be examined, as the tensile capacity of connections may be underestimated.

Guided waves have shown a great potential for structural health monitoring (SHM) applications. In contrast to traditional non-destructive testing (NDT) methodologies, a key element of SHM approaches is the high process of automation. The monitoring system should decide autonomously whether the host structure is intact or not. A basic requirement for the realization of such a system is that the sensors are permanently installed on the host structure. Thus, baseline measurements become available that can be used for diagnostic purposes, i.e., damage detection, localization, etc. This paper contributes to guided wave-based inspection in anisotropic materials for SHM purposes. Therefore, computational strategies are described for both, the solution of the complex equations for wave propagation analysis in composite materials based on exact elasticity theory and the popular global matrix method, as well as the underlying equations of two active damage localization algorithms for anisotropic structures. The result of the global matrix method is an angular and frequency dependent wave velocity characteristic that is used subsequently in the localization procedures. Numerical simulations and experimental investigations through time-delay measurements are carried out in order to validate the proposed theoretical model. An exemplary case study including the calculation of dispersion curves and damage localization is conducted on an exemplary unidirectional composite structure where the ultrasonic signals processed in the localization step are simulated with the spectral element method. The proposed study demonstrates the capabilities of the proposed algorithms for accurate damage localization in anisotropic structures.

Under the recent global business environment and active e-commerce era through digital media, the decision on the exporting companies' brand and web domain development is a very crucial strategic choice. Especially, since web domain development is closely related with company's brand strategy, this study is conducted to research the decisive factors of exporting brand strategy on the basis of the need research results on Korean exporting company's overseas brand and domain development strategy. As presented in statistical results, in case of Korean exporting businesses, the level of OEM brand export was when there was high export competitiveness and the level of OEM brand export was high when there was higher uncertainty about the environment. This supports the hypotheses on the basis of existing research documents. However, the similarities of markets failed to bring out any statistical meaningful influence. As the second result, businesses with high export competitiveness tend to select global brand strategy and businesses with high environment uncertainty tend to choose local brand strategy. However, the similarity of markets failed to show any statistical meaningful influence.
