The purpose of this study was to examine strategies which clothing manufacturers had employed to make themselves more competitive in the era of fast fashion. The Zimbabwean fashion industry is facing fierce competition from imported fast-fashion products which are lower priced and offer consumers a variety of designs from which to choose. The study made use of a qualitative approach with multiple case study design. In-depth interviews were used to gather data from participants, who were selected using the purposive sampling. The study found that clothing manufacturers had resorted to sub-contracting garment manufacturing work, promoting the buy-Zimbabwe campaign and developing in-house brands. This study offers insights into how the fast-fashion era has impacted the local fashion industry and unveils the practical solutions that local clothing manufacturers have embraced in a bid to remain operational and become globally competitive.

The Proper Orthogonal Decomposition (POD) is a statistical method particularly suitable and versatile for dealing with many problems concerning wind engineering and several other scientific and humanist fields. POD represents a random process as a linear combination of deterministic functions, the POD modes, modulated by uncorrelated random coefficients, the principal components. It owes its popularity to the property that only few terms of the series are usually needed to capture the most energetic coherent structures of the process, and a link often exists between each dominant mode and the main mechanisms of the phenomenon. For this reason, POD modes are normally used to identify low-dimensional subspaces appropriate for the construction of reduced models. This paper provides a state-of-the-art and some prospects on POD, with special regard to its framework and applications in wind engineering. A wide bibliography is also reported.

This study conducted scientific analyses on eight objects of wooden lacquerware to understand the manufacturing techniques of wooden lacquerware in the late Joseon Dynasty. The results of lacquer layer analysis with a microscope and scanning electron microscopy-energy dispersive X-ray spectrometry revealed that most samples were composed of 1-3 lacquer layers. Moreover, a red-colored layer was found to be red ocher and cinnabar, and Fourier-transform infrared spectroscopy analysis was carried out to determine the components of the lacquer layer. The detected components were mostly lacquer and partially cashew shell nut liquid.

The purpose of this study is to analyse existing hysteresis models and to propose a new type of model. The existing hysteresis models are classified by three types: interpolation model, scaling model and domain model, of which the domain model is based on the theoretical approach. Models which need one branch of hysteresis loop for calibration are developed based on the independent domain concept, however, they are not successful to accurately simulate the real data and Rubicon Sandy Loam and Dune Sand. There is a possibility that a new model is based on the dependent domain model considering the pore blockage effect against air entry for homogeneous porous media(modelIII-1, Mualem, 1984). Concludingly, a new type of hysteresis model is proposed by simplifying ModelIII-1 using a proper assumption.

The article presents ARTMAP and Fuzzy BK-Product approach underwater obstacle avoidance for the Autonomous underwater Vehicles (AUV). The AUV moves an unstructured area of underwater and could be met with obstacles in its way. The AUVs are equipped with complex sensorial systems like camera, aquatic sonar system, and transducers. A Neural integrated Fuzzy BK-Product controller, which integrates Fuzzy logic representation of the human thinking procedure with the learning capabilities of neural-networks (ARTMAP), is developed for obstacle avoidance in the case of unstructured areas. In this paper, ARTMAP-Fuzzy BK-Product controller architecture comprises of two distinct elements, are 1) Fuzzy Logic Membership Function and 2) Feed-Forward ART component. Feed-Forward ART component is used to understanding the unstructured underwater environment and Fuzzy BK-Product interpolates the Fuzzy rule set and after the defuzzyfication, the output is used to take the decision for safety direction to go for avoiding the obstacle collision with the AUV. An on-line reinforcement learning method is introduced which adapts the performance of the fuzzy units continuously to any changes in the environment and make decision for the optimal path from source to destination.

The purpose of this study is the fundamental study to develope basic slacks pattern for pregnant women by analysing characteristics of the lower half of their body. The results are as followers: 1. The pregnancy has changed almost all items including the waist height, lengths and etc. and changed proportion of body by accumulation of fat. 2. The changes of the waist circumference and flat figure from waist to hip could be found by analysing the body shell (pregnant women from five months pregnance to one month after delivery). 3. The postures of five month-pregnant women were compared with those of six, seven, eight, and nine month-pregnant women, and with those of one month after delivery. The waist height has been increased till the middle of pregnancy but lowed till the end of the pregnancy.

In ocean industry, free surface type ART (Anti Roll tank) system has been widely used to suppress the roll motion of floating structures. In those, various obstacles have been devised to obtain the sufficient damping and to enhance the controllability of freely rushing water inside the tank. Most of previous researches have paid on the development of simple mathematical formula for coupled ship-ARTs analysis although other numerical and experimental approaches exist. Little attention has been focused on the use of 3D panel method for preliminary design of free surface type ART despite its advantages in computational time and general capacity for hydrodynamic damping estimation. This study aims at developing a potential theory based hydrodynamic code for the analysis of floating structure with baffled ARTs. The sloshing in baffled tanks is modeled through the linear potential theory with FE discretization and it coupled with hydrodynamic equations of floating structures discretized by BEM and FEM, resulting in direct coupled FE-BE formulation. The general capacity of proposed formulation is emphasized through the coupled hydrodynamic analysis of floating structure and sloshing inside baffled ARTs. In addition, the numerical methods for natural sloshing frequency tuning and estimation of hydrodynamic damping ratio of liquid sloshing in baffled tanks undergoing wave exiting loads are developed through the proposed formulation. In numerical examples, effects of natural frequency tuning and baffle ratios on the maximum and significant roll motions are investigated.

The paper presents the state-of-the-art in aerodynamic performance of the modern horizontal axis wind turbine. The study examines the different complexities involved with wind turbine blade aerodynamic performance in open atmosphere and turbine wakes, and highlights the issues which require further investigations. Additionally, the latest concept of smart blades and frequently used wind turbine design analysis tools have also been discussed. The investigation made through this literature survey shows significant progress towards wind turbine aerodynamic performance improvements in general. However, still there are several parameters whose behavior and specific role in regulating the performance of the blades is yet to be elucidated clearly; in particular, the wind turbulence, rotational effects, coupled effect of turbulence and rotation, extreme wind events, formation and life time of the wakes.

Korean foods have the strengths to addresssome of the health problems of modern man. To assess the properties of Korean noodles, daily value %, DVS, DDS and energy density were compared between many kinds of noodles from around the world. Using a variety of reference materials, a nutritional database of noodles was built for this study. For carbohydrate, lipid, vitamin A, vitamin K, vitamin C, niacin, zinc, and copper, the daily values % of western noodles were significantly higher. Also, the serving size of Korean noodles was significantly small. Comparing the average energy density of the noodles, they showed $1.87{\pm}0.93kcal/g$ (Korean noodles), $2.42{\pm}1.08kcal/g$ (western noodles) and $1.84{\pm}0.84kcal/g$ (other noodles). The dietary fiber, polyphenols, and flavonoids content of the noodles showed no significant difference. Neither DVS nor DDS showed a statistically significant difference. In the Korean noodles, the GMDFV pattern showed a diverse choice of food groups. Korean noodles show a lower energy density, and the small serving size to have favorable for the prevention of obesity. Thus, Korean noodles are an excellent choice in terms of diversity and energy density.

The purpose of this study is to examine the realities of the chaotic use of terms, 'tattoo' and 'moonsin', through the empirical field researches. This paper will research the differences in the origins and the etymological meanings of 'tattoo' and 'moonsin' through examining related literatures. Clarifying the term definitions on 'tatto' and 'moonsin', this research is to help fashion consumers to use these terms discretely. In order to figure out consumers' perceptive attitude, this study has performed the questionnaire inquiry and has reached the result by analyzing the level of frequency of using the two terms. 1. The result of the term-preference inquiry tells that consumers prefer 'tattoo' to 'moosin'. However, the inquiry shows considerable number of them use the two terms indiscretely. 2. The study on the perceptions from the two terms shows: the term 'tattoo' is often related to positive images-fashionable, charming, and sexy, and the term 'moonsin' to negative ones-violent, anti-social, and demonic. 3. Both 'tattoo' and 'moonsin' shares the similarity in terms of engraving patterns on skin and coloring them. 4. 'Tattoo' is originally derived from the Polynesian word 'tatau', which means 'artistic'. 'Tatau' is a kind of ethnic art practiced on Polynesian people's skin. The design patterns and practicing techniques are very similar to those on the Polynesian earthware called 'Lapita'.
