A secure entrance system is complicated because it should have various functions like monitoring, logging, tracing, authentication, authorization, staff locating, managing staff enter-and-leave, and gate control. In this paper, we built and applied a secure entrance system for a domestic nuclear plant using Aspect Oriented Programming(AOP) and design pattern. Using AOP has an advantage of clearly distinguishing the role for each functional module because building a system separated independently from the system's business logic and security logic is possible. It can manage system alternation flexibility by frequent change of external environment, building a more flexible system based on increased code reuse, efficient functioning is possible which is an original advantage of AOP. Using design pattern enables to design by structuring the complicated problems that arise in general software development. Therefore, the safety of the system can also be guaranteed.

The purpose of this study is to apply the types of urban street pattern and the shape of streets to the master plan of a religious community complexes. The street pattern is a framework of urban structure and to understand the urban structure is helpful to understand the nature of urban streets. By analysing the precedent researches, the types of street patterns are classified as a serial pattern, a branching pattern, a grid pattern and a web pattern. The street patterns are hierarchically composed and classified as a differential development and sequential development. There are boundaries and gates where the street space is differentiated to the more private level. The urban streets continue to the architectural streets such as arcades, deck streets, corridors, lobbies and halls. The purposes and results of the master plan of this religious community complexes are as follows. 1) The school area, housing area and service area are properly separated and connected. They are separated by the building masses and connected by the street space in between. 2) The street pattern of this complexes is a serial pattern where the streets are the center of each functional building groups.

This paper is on a design of the high-speed cipher IC using IDEA algorithm. The chip is consists of six functional blocks. The principal blocks are encryption and decryption key generator, input data circuit, encryption processor, output data circuit, operation mode controller. In subkey generator, the design goal is rather decrease of its area than increase of its computation speed. On the other hand, the design of encryption processor is focused on rather increase of its computation speed than decrease of its area. Therefore, the pipeline architecture for repeated processing and the modular multiplier for improving computation speed are adopted. Specially, there are used the carry select adder and modified Booth algorithm to increase its computation speed at modular multiplier. To input the data by 8-bit, 16-bit, 32-bit according to the operation mode, it is designed so that buffer shifts by 8-bit, 16-bit, 32-bit. As a result of simulation by 0.25 $\mu\textrm{m}$ process, this IC has achieved the throughput of 1Gbps in addition to its small area, and used 12,000gates in implementing the algorithm.

To deploy Gate Recurrent Units (GRU) on resource-constrained embedded devices, this paper presents a reconfigurable FPGA-based GRU accelerator that enables structured compression. Firstly, a dense GRU model is significantly reduced in size by hybrid quantization and structured top-k pruning. Secondly, the energy consumption on external memory access is greatly reduced by the proposed reuse computing pattern. Finally, the accelerator can handle a structured sparse model that benefits from the algorithm-hardware co-design workflows. Moreover, inference tasks can be flexibly performed using all functional dimensions, sequence length, and number of layers. Implemented on the Intel DE1-SoC FPGA, the proposed accelerator achieves 45.01 GOPs in a structured sparse GRU network without batching. Compared to the implementation of CPU and GPU, low-cost FPGA accelerator achieves 57 and 30x improvements in latency, 300 and 23.44x improvements in energy efficiency, respectively. Thus, the proposed accelerator is utilized as an early study of real-time embedded applications, demonstrating the potential for further development in the future.

At the time when interest in the use of big data is rising in the face of the technological paradigm shift of the 4th industrial revolution, interest in the use of patented big data is increasing, especially as the proportion of intangible assets of companies increases. In addition to quantitative information, patent data contains various information such as unstructured text such as title, abstract, claim, citation and citation relations, drawings, and technology classification. It is judged that the use of treatment is important. Therefore, in this study, in order to systematically operate the innovative patent strategy framework and to secure a competitive advantage by strengthening the fundamental technological competitiveness of the company, we propose a method of using patent big data centering on the case of Company A, and verify its validity. I would like to suggest some implications. Through this, it is intended to raise awareness of the use of patent big data, and to suggest ways to use patent big data in connection with the company's company-wide strategy, business strategy, and functional strategy.

In this paper, on the assumption that MPI collective communication function is converted into a group of point-to-point communication functions in the transaction level, an algorithm that optimizes broadcast, scatter and gather function among MPI collective communication is proposed. The MPI hardware engine that operates the proposed algorithm was designed, and it was named the OCC-MPE (Optimized Collective Communication Message Passing Engine). The OCC-MPE operates point-to-point communication by using the standard send mode. The transmission order is arranged according to the algorithm that proposes the most frequently used broadcast, scatter and gather functions among the collective communications, so the whole communication time is reduced. To measure the performance of the proposed algorithm, the OCC-MPE with the Bus Functional Model (BFM) based on SystemC was designed. After evaluating the performance through the BFM based on SystemC, the proposed OCC-MPE is designed by using VerilogHDL. As a result of synthesizing with the TSMC $0.18{\mu}m$, the gate count of each OCC-MPE is approximately 1978.95 with four processing nodes. That occupies approximately 4.15% in the whole system, which means it takes up a relatively small amount. Improved performance is expected with relatively small amounts of area increase if the OCC-MPE operated by the proposed algorithm is added to the MPSoC (Multi-Processor System on a Chip).

This thesis study of the medical concept Qiu Zheng Lu (求正錄) is discussed in the Lei Jing Fu Yi (類經附翼), a book authored by Zhang Jie Bin (張介賓) a medical doctor during the Chinese Ming (明) dynasty (1368-1683). The meaning of Qiu Zheng Lu (求正錄) is "searching for the rightness." In his book Zhang Jie Bin (張介賓) intended to clarify Qiu Zheng Lu (求正錄) by delineating the concept into four categories. These are: Sanjiao Baoluo Mingmen Bian (三焦包絡命門 辨) the theory of the triple warmer, the Pericardium, the Gate of Life ; Da Bao Lun (大寶論) the theory of the great treasure of the human body; Zhen Yin Lun (眞陰論) the theory of true-yin fluid; and Shi Er Zang Mai Hou Bu Wei Lun (十二臟脈候部位論) the theory of the part of the pulse and its condition in regards to the twelve viscera. Sanjiao Baoluo Mingmen Bian (三焦包絡命門辨), the theory of the triple warmer, the Pericardium, the Gate of Life. The triple warmer (三焦: Sanjiao) is composed of three parts: the upper, middle, and lower. This concept is also connected with the functions and roles of the vital organs. The upper burner is related to the heart and lungs. The middle burner is related to the liver and spleen. Whereas, the lower burner is related to the kidneys. Bao-Luo (包絡) is the Pericardium, the envelope of the heart, serving as the protector of the heart. Ming-Men (命門) is the Gate of Life, reffering to the vitals of life. It functions as kidney-yang which is considered as the origin of yang-energy of the human body, and serves partly as the function of cortico-adrenal gland in modern medicine. Zhang Jie Bin (張介賓) discussed the Da Bao Lun (大寶論) as the most important function in the human body because the Da Bao (大寶/great treasure) is the true-yang (眞陽) which is the affective force for physiological functions, and as the source of energy for life activities. Moreover, true-yang (眞陽) functions both as a heater and thermometer that warms the human body and indicates vitality by levels of body warmth respectively. The Zhen Yin Lun (眞陰論) theory states that if true-yang (眞陽) is energy, then true-yin (眞陰) is the source of energy. This can be likened to a tree with roots which absorbs nutrients from the ground (source), and spreads the nutrients (energy) through its branches. Thus, true-yin (眞陰) is the root cause for later functional activities of true-yang (眞陽). In Shi Er Zang Mai Hou Bu Wei Lun (十二臟脈候部位論) the theory of the pulse (脈 /Mai) and its condition in regards to the twelve viscera, Zhang Jie Bin (張介賓) insisted that when a diagnoses by the pulse is made the five vital organs and the six viscera (五臟六腑) of a human body should be harmoniously arranged in accordance with its respective part of the pulse. Furthermore, Zhang Jie Bin (張介賓) supported his theory with evidence from earlier Chinese medical doctors. And, by stating that human beings must cultivate and preserve their true-yin (眞陰) and true-yang (眞陽) energies he therefore created four new prescriptions called: Zuoguiyin (左歸飮), Youguiyin (右歸飮), Zuoguiwan (左 歸丸), Youguiwan (右歸丸). To further clarify his theory Zhang Jie Bin (張介賓) considered that the function of true-yang (眞陽) and true-yin (眞陰) is expressed by Ming-Men (命門). This theory is that for humans to be spiritually and physically healthy they must live in accord with natural law. Also, within the framework of natural law, astronomical and geographical factors must be considered for complete, holistic, health. Thus, Ming-Men is the basis for healthy living in the modern world.

An analysis of heart movement is to estimate a role which supplies blood in human body. We have constructed a left ventricle myocardium model and mathematically evaluated the motion of myocardium. The myocardial motility was visualized using some parameters about cardiac motion. We applied the myocardium model in the gated myocardium SPECT image that showed a cardiac biochemical reaction, and analyzed a motility between the gated myocardium SPECT image and the myocardium model. The myocardium model was created of the based on three dimensional super-ellipsoidal model that was using the sinusoidal function. To express a similar form and motion of the left ventricle myocardium, we calculated parameter functions that gave the changing of motion and form. The LSF algorithm was applied to the myocardium gated SPECT image data and the myocardium model, and finally created a fitting model. Then we analyzed a regional motility direction and size of the gated myocardium SPECT image that was constructed on a fitting model. Furthermore, we implemented the Bull's Eye map that had evaluated the heart function for presentation of regional motility. Using myocardium's motion the evaluation of cardiac function of SPECT was estimated by a contraction ability, perfusion etc. However, it is not any estimation about motility. So, We analyzed the myocardium SPECT's motility of utilizing the myocardium model. We expect that the proposed algorithm should be a useful guideline in the heart functional estimation.
