  • The purpose of this paper was to present the proximity of clothing to self(PCS) which is a subjective measure developed by Sontag and Lee(2004). PCS is the scale to examine the relationship between self and clothing. Since PCS scale was prepared for American consumers, it is necessary to verify the validity as a measure to Korean consumers. Consumers' quality of life are functionally related to satisfaction with all of life's domain and subdomains. Clothing in life facilitates the creativity and expressiveness to the wearer, especially to adolescent. The concept of bottom-up spillover effect developed by Lee et al.(2002) was adopted as research model. Data were gathered by surveying university students using convenient sampling, 419 questionnaires were used in the statistical analysis. It was proved that PCS scale was effective measure to Korean consumers. And also PCS scale could be a proxy indicator in view of the fact that clothing was deeply related to consumers' quality of life.

  • In general, the numerous classical approaches available in the literature can anticipate the settlement of shallow foundations. As long as the footings are not in close proximity to other subsurface buildings, the findings achieved using these methods are legitimate and acceptable. However, due to increased urbanisation and land scarcity, footings are frequently built close together. As a result, these footings' settlement behaviour differs from those of isolated footings. A simpler approach for assessing the settlement behaviour of two square or rectangular footings placed in close proximity is presented in this work. A Parametric study has been carried out to examine the interference effect on the settlement of these footings placed in close vicinity on the surface of a homogeneous, isotropic and elastic soil medium. The interaction factors are examined by varying the different aspect ratios (L/B), clear spacing ratio (S/B) and intensity of loading on the right footing with respect to the left footing. Further, variation of the settlement ratio (δ/B) with respect to embedment depth ratio Df/B is examined. For square and rectangular footings, the interference settlement profile is also investigated by varying the clear spacing ratio (S/B) and the degree of loading. The results were compared to 3D finite element analysis and experimental data that were available.

  • A numerical simulation of wake behavior behind three-dimensional wings in ground effect is done using an indirect boundary element method (Panel Method). An integral equation is obtained by applying Green's 2nd Identity on all surfaces of the flow domain. The AIC is constructed by imposing the no penetration condition on solid surfaces, and the Kutta at the wing's trailing edge. The ground effect is included using an image method. At each time step, a row of wake panels from wings' trailing edge are convected downstream following the force-free condition. The roll-up of wake vortices behind wings in close proximity is simulated.

  • As high-rise buildings become more and more slender and flexible, the wind effect has become a major concern to modern buildings. At present, wind engineering for high-rise buildings mainly focuses on the following four issues: wind excitation and response, aerodynamic damping, aerodynamic modifications and proximity effect. Taking these four issues of concern in high-rise buildings as the mainline, this paper summarizes the development history and current research progress of wind engineering for high-rise buildings. Some critical previous work and remarks are listed at the end of each chapter. From the future perspective, the CFD is still the most promising technique for structural wind engineering. The wind load inversion and the introduction of machine learning are two research directions worth exploring.

  • This study examined the impacts of the cultural proximity of Chinese consumers on the image of both country and product, and investigated how they are related to purchase intention of Korea fashion. Subjects were Chinese female consumers in their 20s and 30s, living in Yangtze River delta and Seoul. The results of the study were as follows: 1) The cultural proximity had a significant influence on the country image and fashion product image. Chinese consumers with more emotional proximity had more positive attitude towards country image, such as politics, economics, technology, cultures and people image. And consumers who had higher interest in Korea and Korean culture evaluated the quality, design, value and reputation of Korean fashion more positively. 2) Chinese consumers with positive attitude towards people, technology and culture image seemed to prefer fashion product. Specifically, the dimensions of country image had a different influence on the fashion product image such as product quality, design, value, reputation. 3) The Korea country image and fashion product image had also affected on purchase intention of Korean fashion products. Consumers with positive attitude towards people and technology image had higher purchase intention of Korea fashion products. And consumers with positive attitude towards reputation, value and design of fashion products had higher purchase intention of fashion products.

  • Objectives: This study examined the effects of residential proximity to adult children on the mental and physical health of middle-aged and older parents. The study also evaluated whether the parental age and gender of the adult child in closest proximity to the parent might moderate the association. Method: Data were drawn from five waves of the Korean Longitudinal Study of Aging(2006-2014). The analytic sample consisted of 7,359 parents aged 45 or older who had at least one non-coresidential adult child aged 19 or older. The analyses were conducted by estimating a series of fixed effects models while adjusting for the nested structure of the data. Results: The results showed that first, a closer distance between an adult child and the parent was generally associated with the parent experiencing a decrease in depressive symptoms. Yet, the mental health benefit was smaller for parents aged 65 years or older whose closest living adult child was a son. Second, a closer distance was observed to affect chronic illness only among middle-aged parents (aged 45 to 64). When the closest living adult child was a daughter, the middle-aged parent experienced deterioration in their chronic illness. On the other hand, the opposite pattern was observed when the closest living adult child was a son. Conclusions: The parental age and gender of the adult child in closest proximity to the parent might have varying effects on parents' health. A closer distance between an adult child and their parent has a positive impact on the mental health of the parent as a whole, whereas the effect of living closer was mixed in relation to the parental physical health.

  • The unsteady turbulent flow characteristics of NACA4406 airfoil at close proximity to the pound are numerically investigated, especially focused on the noise generation mechanism near the blunt trailing edge. The unsteady two-dimensional compressible Wavier-Stokes equations with a Spalart-Allmaras turbulence closure model are solved by the 6th-order compact scheme and the 4th-order Runge-Kutta scheme. The computation shows a noise generation by a feedback mechanism at the blunt tailing edge, where the acoustic-fluidic coupling occurs between the wall-reflected sound waves and the periodically disturbed turbulent shear layer.

  • InAs semiconductor nanowires can provide a promising platform to integrate superconducting quantum circuit, which exploits tunable supercurrent under the operation of gate voltage. We report temperature and magnetic field dependence of the nanowire superconducting junctions, which is in agreement with the proximity-effect theory of superconductor-normal metal-superconductor weak link. Superconducting coherence length of the InAs nanowire is estimated from the fit and magnetic-field dependence of the critical current and the subgap structure of dI/dV is discussed as well.
