This study identified the characteristics of fashion rental service users as well as analyzed their purchase decision-making processes. A qualitative investigation was conducted through in-depth interviews with 13 women in their 20s-30s who have experienced renting fashion items due to a high interest in fashion. The results of the study are summarized as follows. The need recognition stage analyzed ventilation by mass media, SNS impact, curiosity, saving shopping time and money, awareness of situational necessity, and creation of various styles. The information search stage analyzed how users obtained information from 2 different sources of nonmarketer-dominated sources and marketer-dominated sources. The pre-purchase stage analyzed the evaluation of alternatives in which study participants used 2 evaluation criteria for fashion rental services and fashion rental items. The purchase stage analyzed how participants wait and select desired items (when receiving the notification of rentable items) or select alternative products. The consumption stage examined the usage frequency and usage method. The study divided the post-consumption evaluation stage into 2 categories for evaluation: personal feelings and service. The post-consumption behavior stage analyzed how participants displayed WOM, eWOM and purchase rental product behavior. Clothing shopping orientation of study participants is displayed in 5 dimensions of brand-seeking propensity, individuality-seeking propensity, economic efficiency-seeking propensity, rationality-seeking propensity, and pleasure-seeking propensity. This study identified three main characteristics in the study participants: interest in the fashion, favorable attitude toward used fashion items, consciousness of others.

Purpose: The baby boomers and the millennials, who make up the largest share of the market, are showing the gap in their differentiated cultural styles. The purpose of this study is to study the consumption propensity and purchasing determinants of the baby boomers generation and the millennials generation, which have become a very important key pillar in shaping the market based on the cultural dimension model theory of h(=>H)opstead, and to identify the difference Research design, data, and methodology: In order to verify the research hypotheses, The data was collected from the baby boomers and the millennials using online questionnaires. The pre-test was conducted from October 10 to 12, 2019, and the main survey was conducted from October 15 to 25. A total of 230 copies were recalled, and the final 219 copies were used for the final analysis. Results: The consumption propensity between the baby boomers and the millennials differed in resource saving purchase propensity and impulse buying propensity. The baby boomers showed higher resource saving purchase propensity than the millennials, while the millennials showed higher impulse buying propensity. There was a difference in the determinants to purchasing only in the evaluation factor. Results of gender differences by generation, baby boomers differed in their planned purchase propensity, and women were higher. The millennials generation differed in resource saving purchase propensity and awareness propensity for others, all higher in men. In determinants to purchasing, the baby boomers did not differ in gender, and the millennials did differ in product factors. A canonical correlations analysis of the relationship between the baby boomers and the millennials showed a significant relationship between consumption propensity and determinants to purchasing. Also, the baby boomer generation has the biggest link between impulse buying propensity and evaluation factor. The millennials generation showed the biggest link between resource saving purchase and product factors. Conclusions: This study compared consumption propensity and determinants to purchasing of baby boomers and millennials on the basis of Hopstead's cultural dimension model theory to identify differences between generations, presenting practical and theoretical implications for establishing a correct understanding and specific marketing strategy among generation.

A large percentage of maritime accidents in coastal seas are related to small fishing vessels. In order to investigate causes of maritime accidents, it is often necessary to carry out dynamic simulations for the estimation of trajectories and motions of vessels. Initial conditions of vessels such as main dimensions, loading conditions and hydrostatic properties are required for the accurate simulations. Small fishing vessels usually have few records of hydrostatic properties during their fishing operations. Therefore, in this study, estimation procedures for hydrostatic properties of small fishing vessels are proposed. At first, hull form characteristics of Korean small fishing vessels are investigated. Most of vessels have hard-chines and centerline skegs, they have similar hull forms. Bonjean curves of several small fishing vessels whose gross tonnages are below 10 tons are normalized with vessel breadths and depths. Representative bonjean curves are derived from normalized bonjean curves, and a representative hull plan is obtained as well. If the vessel loading conditions such as total weights and centers of gravity are given, fore and aft drafts can be calculated by using the representative bonjean curves with the constraint that weights and buoyancies are in equilibrium. Metacentric heights are also estimated by using the representative hull plan. Drafts and metacentric heights estimated by proposed iterative estimation procedures are compared with actual vessel data, estimated values are in good agreements with actual values. In addition, normalized fore and aft drafts, metacentric heights of vessels can be formulated as the linear functions of normalized total weights and centers of gravity. Empirical formulas of drafts and metacentric heights are proposed, and it is confirmed that the empirical formulas also provide reasonable results, which are similar to the results by iterative estimation procedures with representative bonjean curves and hull plan.

In urban cities, buildings were built in the neighborhood, these buildings influence each other through structure-soilstructure interaction (SSSI) and seismic pounding due to limited separation distance in-between. Generally, the effects of the interaction between soil and structure are disregarded during seismic design and analysis of superstructure. However, the system of soil-base adversely changes structural behavior and response demands. Thus, the vibration characteristics plus the seismic response of a building are not able to be independent of those in adjacent buildings. The interaction between structure, soil, and structure investigates the action of the attendance of adjacent buildings to the others by the interaction effect of the sub-soil under dynamic disturbances. The main purpose of this research is to analyze the effects of SSSI and seismic pounding on the behavior of adjacent buildings. The response of a single structure or two adjacent structures with shallow raft base lying on soft soil are studied. Three dimensions finite element models are developed to investigate the effects of pounding; gap distance; conditions of soil; stories number; a mass of adjacent building and ground excitation frequency on the seismic responses and vibration characteristics of the structures. The variation in the story displacement, story shear, and story moment responses demands are studied to evaluate the presence effect of the adjacent buildings. Numerical results acquired using conditions of soil models are compared with the condition of fixed support and adjacent building models to a single building model. The peak responses of story displacement, story moment, and story shear are studied.

A-PET is a quad-head PET scanner developed for use in small-animal imaging. The dimensions of its volumetric field of view (FOV) are $46.1{\times}46.1{\times}46.1mm^3$ and the gap between the detector modules has been minimized in order to provide a highly sensitive system. However, such a small FOV together with the quad-head geometry causes image quality degradation. The main factor related to image degradation for the quad-head PET is the mispositioning of events caused by the penetration effect in the detector. In this paper, we propose a precise method for modelling the system at the high spatial resolution of the A-PET using a LOR (line of response) based ML-EM (maximum likelihood expectation maximization) that allows for penetration effects. The proposed system model provides the detection probability of every possible ray-path via crystal sampling methods. For the ray-path sampling, the sub-LORs are defined by connecting the sampling points of the crystal pair. We incorporate the detection probability of each sub-LOR into the model by calculating the penetration effect. For comparison, we used a standard LOR-based model and a Monte Carlo-based modeling approach, and evaluated the reconstructed images using both the National Electrical Manufacturers Association NU 4-2008 standards and the Geant4 Application for Tomographic Emission simulation toolkit (GATE). An average full width at half maximum (FWHM) at different locations of 1.77 mm and 1.79 mm are obtained using the proposed system model and standard LOR system model, which does not include penetration effects, respectively. The standard deviation of the uniform region in the NEMA image quality phantom is 2.14% for the proposed method and 14.3% for the LOR system model, indicating that the proposed model out-performs the standard LOR-based model.

The purpose of this study is to analyze the traditional embroidery in India by region based on Bourdieu's cultural theory. As the research methods for this study, literature and case studies were conducted. The results of the study are summarized as follows. First, India's regions could be divided into four distinct regions based on language and religion. The main concepts of Bourdieu's cultural theory, namely the sub-dimensions of field and habitus, were the field of social system, the field of goods & economy, the field of environment/region, culture, and ethnicity. Second, Eastern India's embroidery was influenced by Hinduism and traditional art. The embroidery used various fabrics such as the Applique work, and vivid colors and patterns were mainly used in the Hindu myths, animals, and flower patterns of the embroidery. Third, embroidery in Western India was influenced by exotic cultures like Persian due to geographical conditions, and embroidery via the use of gold threads and various ornaments was developed. Symbolized flower patterns and geometric patterns were used a lot in the respective embroidery. Fourth, embroidery in southern India was influenced by the Dravidian culture and their architectural style, which saw the emergence of an embroidery that used simple colored cross-stitch. Most of the patterns in this embroidery are geometricized. Fifth, Northern Indian embroidery has historically served as the center of power, resulting in an embroidery that uses various forms and materials. In this embroidery, flower patterns are mainly used. Finally, the characteristics of the traditional embroidery of India's each region is based on Bourdieu's cultural theory, which could be summarized as ethnic religiosity, exotic splendor, structural formality, and symbolic power.
