The types of China Ancientry Architecture are rich and colorful. Among all these architectures, the Traditional Residence Architecture have the closest relationship with the mass's life. Traditional Residence Architecture reflected the connotation of the culture, philosophy ideology, especially the relationship between dwelling house and the nature, which can't be ignored by our modern people as well as the modern design. Beijing Sahap-won residence architecture is one of the apotheosis of China Traditional Residence Architecture, it'svery suitable for family's habitation. There's brilliance layout in space; around symmetry and radioactivity in plane, discretion grade in line, independence and continuity in inner spatial, with high privacy and benignity, Before the development and explore of modern APT Architecture design, we should fully understand the feature of Ancientry Residence House, inherit and carry forward its culture. The proposed design is started from the consolidation of the traditional feature of Beijing Sahap-won and the modern residence architecture, therefore to satisfy the modern people's fierce pursuing to the traditional culture.

This study presents results of analysis on fault-related landforms and the Quaternary fluvial landforms, which are important evidences for active faulting by identifying surface deformation, around the Ulsan Fault Zone. In addition, this study suggests lineament map and inferred active fault-line map based on analyzing linearity and continuity of these landforms and by compiling location information of existing active faults. We convince that quantitative tectonic-geomorphological analysis are an effective method for active faults tracking, in particular, considering the conditions of relatively low seismicity and surface ruptured-events in the Korean Peninsula compared to plate boundary active areas. However, research on active fault in South Korea is just an infant stage since the 1990s and requires accumulation of research achievements on development and application of various fault analysis techniques, analysing and standardizing linear structures.

Peltier cells have low efficiency, but they are becoming attractive alternatives for affordable and environmentally clean cooling. In this line, the current article develops closed-form and semianalytical solutions to improve the temperature distribution of Bi₂Te₃ thermoelements. From the distribution, the main objective of the current work-the optimal electric intensity to maximize cooling-is inferred. The general one-dimensional differential coupled equation is integrated for linear and quadratic geometry of thermoelements, under temperature constant properties. For a general shape, a piece-wise solution based on heat flux continuity among virtual layers gives accurate analytical solutions. For variable properties, another piece-wise solution is developed but solved iteratively. Taking advantage of the formulae, the optimal intensity is directly derived with a minimal computational cost; its value will be of utility for more advanced designs. Finally, a parametric study including straight, two linear, barrel, hourglass and vase geometries is presented, drawing conclusions on how the shape of the thermoelement affects the coupled phenomena. A specially developed coupled and non-linear finite element research code is run taking into account all the materials of the cell and using symmetries and repetitions. These accurate results are used to validate the analytical ones.

An analytical method is developed for analysing the contact buckling response of infinitely long, thin corrugated plates and flat plates restrained by a Winkler tensionless foundation and subjected to linearly varying in-plane loadings, where the corrugated plates are modelled as orthotropic plates and the flat plates are modelled as isotropic plates. The critical step in the presented method is the explicit expression for the lateral buckling mode function, which is derived through using the energy method. Simply supported and clamped edges conditions on the unloaded edges are considered in this study. The acquired lateral deflection function is applied to the governing buckling equations to eliminate the lateral variable. Considering the boundary conditions and continuity conditions at the border line between the contact and non-contact zones, the buckling coefficients and the corresponding buckling modes are found. The analytical solution to the buckling coefficients is also expressed through a fitted approximate formula in terms of foundation stiffness, which is verified through previous studies and finite element (FE) method.

Execution of the finish work for high-rise residential construction occurs when a mixture of work progresses simultaneously at each floor or sector and is carried on by highly-specialized subcontractor teams. Therefore, the finish work plan requires an effective scheduling method that interfaces between the work and the teams. In order to address these issues, the TACT technique is utilized in Korea. This technique is based on Line-of-Balance and Lean construction. However, according to recent case studies, finish work using TACT technique was frequently delayed with cost overruns because the work was performed without a detailed schedule control plan outlining the relationship between architecture and mechanical, electrical, and plumbing work. This paper describes the enhanced-TACT technique which provides a detailed work flow chart and TACT work template. With improved TACT technique, this paper will contribute to improved cash flow and reduced cycle time and provide quality improvement through work continuity.

웹의 구조적인 특성으로 인해서 실제 원격 교육 시스템으로 교육 활동을 수행할 때 많은 제한점이 발생된다. 비연결성 프로토콜인 HTTP는 클라이언트의 요청 각각을 별도로 수행하며 연결 상태를 유지하지 않는다. 이것은 학습자의 접속상황을 유지 관리하고 학습자의 요청 정보를 추적하기 어렵게 만든다. 그리고 이는 한 학습자의 연결유지뿐만 아니라 다른 학습자들간의 상호작용 자체를 불가능하게 만든다. 본 연구는 학습자의 학습 활동을 추적할 수 있도록 하기 위해서 HTTP를 기반으로 하여 확장된 연결성 프로토콜인 CHTP를 개발하고, 새로운 원격교육 플랫폼을 구축하였다. 프로토콜 차원에서 표준화된 방식을 제안하기 때문에 개발된 웹 확장 플랫폼은 원격교육을 위한 시스템 구축을 효과적이고 용이하게 만들어 줄 것이다.

Multi-regional water supply system, which installed for supplying multiple water demands, is characterized by large-sized, long-distance, tree-type layout. This system is vulnerable to long-standing service interruption when a pipe breaks is occurred. In this study, a numerical method is proposed to calculate drainage time that directly affects time of service interruption. To begin with, governing equations are formulated to embed the delayed drainage effect by the friction loss, and to resolve complicated connection of pipelines, which are derived from the continuity and energy equations. The nonlinear hydraulic equations are solved by using explicit time integration method and the Newton-Raphson method. The developed model is verified by comparing the result with analytical solution. Furthermore, the model's applicability is validated by the examples of pipelines in serial, in parallel, and complex layout. Finally, the model is utilized to suggest an appropriate actions to reduce the deviation of draining time in the C transmission line of the B multi-regional water supply system.

Let $\mathbb{Z}^n$ be the Cartesian product of the set of integers $\mathbb{Z}$ and let ($\mathbb{Z}$, T) and ($\mathbb{Z}^n$, $T^n$) be the Khalimsky line topology on $\mathbb{Z}$ and the Khalimsky product topology on $\mathbb{Z}^n$, respectively. Then for a set $X\;{\subset}\;\mathbb{Z}^n$, consider the subspace (X, $T^n_X$) induced from ($\mathbb{Z}^n$, $T^n$). Considering a k-adjacency on (X, $T^n_X$), we call it a (computer topological) space with k-adjacency and use the notation (X, k, $T^n_X$) := $X_{n,k}$. In this paper we introduce the notions of KD-($k_0$, $k_1$)-homotopy equivalence and KD-k-deformation retract and investigate a classification of (computer topological) spaces $X_{n,k}$ in terms of a KD-($k_0$, $k_1$)-homotopy equivalence.
