  • The objectives of this study were to be properly understood the residential function and its relations to the mixed functions of the mixed-use buildings and further to provide useful information in future basic planning of mixed-use buildings. 1) The satisfaction rates of the public space and the supplementary facilities were high in general, but the satisfactory rate of the convenience facilities was low. 2) The household characteristics were analyzed as variables that differences among satisfaction rates. However, they were not found to be influential factors in determining residential satisfaction. 3) The residential characteristics were analyzed as variables that differences among satisfaction rates. As a result, the floor and direction of the residence were more meaningful variables than the scale of the residence.

  • The purpose of this research is to analyze the survey of the residential and commercial user consciousness of 4 cases(DB, YM, TP, HG) to propose directions of development of the mixed-use apartments in Daegu. The results of the survey are as follows; 1) The residential users of DG, YM, TP and the commercial users of DG, TP, HG were not satisfied with generally present situation. 2) It showed that the development factors of the satisfaction, the reason of the move, the difficulty to operate the business, the possible use of Mixed-Use Development, the using system of the main entrance, and the reasonable residential size were the statistical significance level(p<0.05). Finally, this study proposes that 4 Cases with the diverse physical and social environment must be different with the approach, and that the reasonable residential space program, size planning for commercial unit, and choices of what kind of business should be discussed before Mixed-Use Development regarding needs of region.

  • The purpose of this study is to analyze architectural plans of lower part of super tall mixed-use residential building for understanding its functions for urban. The area of this research are limited to super tall mixed-use residential building which were built in Seoul, Kyoung-gi area, and new towns. For this purpose, theories for super tall mixed-use residential building and non-housing parts were researched, and characteristics of selected cases for field research were analyzed by studying drawing materials. The research focused on scale, type of building, included programs for public spaces, and characteristics of location. As a result, every cases were designed as 'outdoor transition zone-centered type', and for urban function, non-housing facilities were condensed to increase convenience. In addition, ratio of non-housing part were incresesed with public spaces design for residents, and various programs were inserted.

  • We first apply a first order splitting to a semilinear reaction-diffusion equation and then discretize the resulting system by an $H^1$-Galerkin mixed finite element method in space. This semidiscrete method yields a system of differential algebraic equations (DAEs) of index one. A priori error estimates for semidiscrete scheme are derived for both differ-ential as well as algebraic components. For fully discretization, an implicit Runge-Kutta (IRK) methods is applied to the temporal direction and the error estimates are discussed for both components. Finally, we conclude the paper with a numerical example.

  • The aim of this study is to analyze the tendency of the interior materials used for the apartment units of Mixed-use Apartment. One hundred fourteen cases of 15Mixed-use Apartment which were completed or under construction in Seoul and Bundang area before and after the year 2000 were the examples of this research. For the purpose of this research, following contents were analyzed accordingly. 1. The units were devided into entrance, living room, kitchen, bedroom and bathroom; and finishing material of the floor, wall and ceiling of each individual space were analyzed. 2. The units was categorized into three floor spaces(py) such as 30-49py, 50-70py, 80py and above. And each interior material of different floor spaces(py) were analyzed.

  • In this paper, we provide the performance analyses of a dual-hop amplify-and-forward(AF) relay transmission composed of asymmetric radio-frequence(RF) and free-space optical(FSO) links. In the mixed RF/FSO system, a relay is equipped with two receive antennas for RF signals and one additional transmit antenna for FSO signals. In order to improve a performance of RF link, a switch-and-stay (SSC) diversity technique is applied at the relay which can provide a proper link performance with a low complexity. Specifically, we offer the performance analyses of the proposed system in terms of outage probability and secrecy outage probability. In numerical examples, we compare the system performances with no diversity and selection combining systems and verify our analytical results via computer-based Monte-Carlo simulations.

  • In this paper, we introduce a hybrid iterative method for finding a common element of the set of solutions of a mixed equilibrium problem, the set of common mixed points of finitely many nonexpansive mappings and the set of solutions of the variational inequality for an inverse strongly monotone mapping in a Hilbert space. We show that the iterative sequences converge strongly to a common element of the three sets. The results extended and improved the corresponding results of L.-C.Ceng and J.-C.Yao.

  • This paper presents an optimization procedure for high-efficiency design of a mixed-flow pump. Optimization techniques based on a weighted-average surrogate model are used to optimize a vane diffuser of a mixed-flow pump. Validation of the numerical results is performed through experimental data for head, power and efficiency. Three-level full factorial design is used to generate nine design points within the design space. Three-dimensional Reynoldsaveraged Navier-Stokes equations with the shear stress transport turbulence model are discretized by using finite volume approximation and solved on hexahedral grids to evaluate the efficiency as the objective function. In order to reduce pressure loss in the vane diffuser, two variables defining the straight vane length ratio and the diffusion area ratio are selected as design variables in the present optimization. As the results of the design optimization, the efficiency at the design flow coefficient is improved by 7.05% and the off-design efficiencies are also improved in comparison with the reference design.

  • In this paper, each specimen blended at weight proportions of 80% HDPE to 20% EVA, 70% HDPE to 30% EVA, 60% HDPE to 40% EVA, and 50% HDPE to 50% EVA was manufactured respectively. The insulation performances of the proposed insulator were compared with conventional XLPE, main insulating material of CV cable on the basis of the investigation results of DC insulation performances. From the space charge density, electric field and potential profiles with raising DC voltage and time variation in HE82, distortion of electric field distribution was improved. As EVA mixed into the bulks acts as nucleation in crystallization process of HDPE, the size of spherulites became decreased and finally formed continuous network structure. Ultimately it resulted from extinction of space charge in the interfacial region of spherulites.

  • We report on the design of a three-axis missile autopilot using multi-objective control synthesis via linear matrix inequality techniques. This autopilot design guarantees $H_2/H_{\infty}$ performance criteria for a set of finite linear models. These models are linearized at different aerodynamic roll angle conditions over the flight envelope to capture uncertainties that occur in the high-angle-of-attack regime. Simulation results are presented for different aerodynamic roll angle variations and show that the performance of the controller is very satisfactory.
