This paper discusses a method of determining the optimal design of a block. A horizontal layout of blocks is assumed in which transfer points are located at a side of the block. Each block has several transfer points (TPs) each of which is assigned to a group of adjacent bays and located at the center of the assigned group. The goal is to find the optimal size of a block and the optimal number of TPs while minimizing the total cost consisting of the fixed and operational cost of yard cranes (YCs), the operational cost of internal trucks, and the installation cost of TPs. Constraints on the maximum expected system time of trucks are imposed for the optimization. Formulas for estimating handling operation cycle times of a YC are derived analytically. Numerical experiments are conducted to illustrate optimal block designs for a given set of data.

It is remarkable that the children's wear market has been growing instead of declining birth rate. The parents are willing to pay more when they find children's wear of better design and improved quality. For better quality, it is necessary to research on the pattern making of children's wear. After the interview with the 10 leading children's brands, we found that they develop individual design pattern based on each items middle block pattern which characterize the brands design line. Most frequently used middle block is for casual pants. Through interview with pattern designers, comparative study of patterns drafting methods, wearing test of trial garments and altering and adjustment of patterns, we developed the casual pants block pattern for 7 years old boys.

The purpose of this paper is design the most important part of sequential control systems, that is, command-treatment part, from the signal-transformation point of view. An orderly procedure is developed by which for sequential control systems the experimental design method can be reduced to the rational design method. Important in this procedure are: 1. To make total block diagram of sequential control systems by determining input and output signals of command-treatment part. 2. To partition over-all block diagram by observing each output signal. 3. To design concretely minimum block diagram by using the operational block diagram. By applying the method for partitioning the circuit to the design, the design method for sequential control systems is organized and done rationally without the aid of experiece.

Hospital Architectures in Korea are continuously erected to old-fashioned design, such as a large self-sufficient, but cost-inefficient hospital, in spite of rapidly changing social and healthcare environment. However, changes are slowly coming from inside of itself. This paper analyzed block plans of 7 best Korean hospitals which constructed in recent 20 years in aspects of the purpose of erection, departmental composition, areal composition, mass design and functional zoning of block plans and then, presented the directions of new design trends of hospital architecture in Korea. It is anticipated that hospital architecture will change immensely in the enlarging process of these minor changes.

In recent years, we use overdriving scheme to improve the response time of the liquid crystal. Since conventional overdriving scheme uses memory to perform ideal processing, it is desired to reduce system cost by decreasing the data stored in these SDRAMs. As a general compression method, quantization, sub-sampling and Block Truncation Coding ( BTC ) are used, which process data in block base and cause block effect. So we proposed new data compression method by color space conversion. Because this method compresses luminance and chrominance signal by different ratio, it can efficiently reduce error of block effect in decompression image.

In the last two decades, many researchers proposed various usages of the orthogonal functions such as Walsh, Haar and BPF to solve the system analysis, optimal control, and identification problems from and algebraic form. In this paper, a simple procedure to design and algerbraic observer for the descriptor system is presented by using block pulse function expansions. The main characteristic of this technique is that it converts differential observer equation into an algerbraic equation. And furthermore, a simple recursive algorithm is proposed to obtain BPFs coefficients of the observer equation.

Limit states of a tension member are the yielding of gross section, fracture of net section, and block shear failure. Block shear failure is very complicated than other limit state because of interaction of tension and shear failure. Block shear failure is studied continuously since the 1970s. However, failure model to estimate the strength of block shear failure provided in current design specifications is not reflective of the failure mode observed in the various experimental studies. Comparisons between the experimental results and design rules in various specifications about the block shear failure were conducted in this study. Also, the need for further studies of block shear failure were proposed.

In this paper, we propose a block-based modularity architecture design method for distributed machine learning. The proposed architecture is a block-type module structure with various machine learning algorithms. It allows free expansion between block-type modules and allows multiple machine learning algorithms to be organically interlocked according to the situation. The architecture enables open data communication using the metadata query protocol. Also, the architecture makes it easy to implement an application service combining various edge computing devices by designing a communication method suitable for surrounding applications. To confirm the interlocking between the proposed block-type modules, we implemented a hardware-based modularity application system.

This study was to figure out the design characteristics of court housing type for the purpose of searching for the possibility of applying it to the housing design in Korea. In spite of changes of housing design condition in Korea, especially steep increase in density, there have been changes only in the height of housing block, not in the housing types, layout, spatial organization and other design properties. Due to such a situation, housing in Korea has been criticised as too high, monotonous one - especially types of housing block tend to be fixed into a slab block and a point block. As one of the alternatives to respond to the criticism, this study focused on the positive aspects of the court housing type, and suggested the design direction throughout the analysis of 8 entries in the design competition of EunPyeong New Town, which attempted to overcome the negative problems - mainly the daylighting, orientation, and privacy - and tried to maximize the positive properties of this type of housing.
