Quân sư phụ (君師父) is a concept of respectfulness derived from the Chinese Confucian concepts of sān gāng wǔ cháng (三綱五常, the Three Principles and Five Constant Virtues) and sān cóng sì dé (三從四德, the Four Virtues Applied to the Three Male Figures) that is applied to Vietnamese Confucianism in regards to not only kings but also Chinese Emperors, as well as Chinese culture generally. In his famous literary work Vàng lửa (Golden Fire), Nguyễn Huy Thiệp revealed the Vietnamese attitude to Chinese civilization: "Our country could be characterized as nhược tiểu (弱小, small and weak). Vietnam was like a maiden forcibly deflowered by Chinese civilization. 'She' enjoyed it, but also came to hate it and feel disgraced by it" (Nguyễn 1988). This is a special sentiment or psychological complex of the Vietnamese in relation to Chinese civilization. The research findings are that the Nguyễn Huy Thiệp complex is the rationale behind which the symbol of the ancestral King Lạc Long Quân (貉龍君) was altered via SinoVietnamese motifs in order to develop Vietnamese Confucian thought.

Che Guevara spearheading the Cuban Revolution was not only the icon as the revolutionary to the New-leftists of the 1960s advocating the ideology of Marxism but, as the cultural revolutionary, had a tremendous influence on the younger generation living in the digital age Che Guevara take on a figure of both the symbol of the Leftist but the romantic revolutionary because he had the external features such as black beret, red stars, military upper jackets and trousers, beard and pipe tobacco. In fact, the symbolic image of Che Guevara was made as the popular image by the avantgarde artists and political vanguard forces of the times under the necessity of Cuban government. Afterwards, the image of Che Guevara has been patronized in making people of aware of the resistant and revolutionary image to capital, power and the power of the media and symbolized as the resistant image to the American capital as well as the revolutionary guerrilla. And his image has continued to be reproduced and symbolized for the commercial and political purposes and as the enthusiastic image of youth culture. This can be seen as having been created as a new image by the popular culture formed by the development of the cyber culture and mass media in the cyberspace shaped by contemporary 'N' generations. The use of Che Guevara's symbolic image was made in the fashion field as well as in the cultural and artistic circles. The borrowing of the icon of Che Guevara represented in a fashion field is attributed to his free spirit, and it can be seen that fashion exists as the vehicle for representing both the symbol system and the sign system containing ideologies and texts as the communicator of resistance to the regime and to social issues. Therefore, this study attempted to investigate the commercial iconization of Che Guevara in the 1990s by comparing the ideology of the symbol in the 1960s and the 1990s and inquire into the borrowing of his image by the fashion domain as well as the fashion worn by him by reference to domestic books and materials on the fashion site. Thereby, this study attempted to make clear that the borrowing of Che Guevara in the realm of fashion since the 1990s not only contained the meaningful interpretation as the symbolic code in the culture of young people living in a digital era but fashion performs an intervening role in the cultural phenomenon.

The purpose of this study is considering about the fashion of Korean National Flag in the point of view of sociology and philosophy. The contents are the philosophy of the Korean National Flag-'Taegk', the Great Absolute in Korean philosophy, and the historical fashion trend of The Korean National Flag. The results of characteristics of The Korean National Flag are summarized as following; 1. The Korean National Flag contains 'Taegk' philosophy, the source of the dual principle 'Yn' and 'Yang'. 2. The design of 'Taegk' has been showed in Korean society traditionally. 3. The fashion of Korean National Flag dramatically is changed after Korea/Japan World cup 2002. 4. The Korean National Flag is the strong symbol of Korean society, affirmatively, same as the American National Flag.

This study attempts to identify the relationship between students' images of science and science learning, and their career choices. A total of 163 students (seventh graders) from three different middle schools participated in this study. Students' images of science and science learning were investigated using the Draw-A-Scientist Test (DAST) and the Draw-A-Science-Learner Test (DASLT), respectively. Then, students' drawings were analyzed using the Draw-A-Scientist Test Checklist (DAST-C) and the Draw-A-Science-Learner Test Checklist (DASLT-C). The relationship between each element composing the students' images and their career choices were analyzed. Among several elements constituting the students' image of science, 'expression,' 'lab coat,' 'oddity,' 'knowledge symbol,' 'technology symbol,' 'co-work,' 'danger,' and 'STS' showed significant differences between students who chose a science-related career and students who did not. It was also revealed that the following elements - 'expression,' 'learning type,' 'inquiry symbol,' and 'learning place' - were more significantly associated with a science-related career choice compared to other elements consisting of an image of science learning.

An idea to improve the performance of error correction with the amplification of input symbol errors is proposed to ease the mismatching problem which occurs in the hardware implementation of the differential analog PRML decoder. The differential analog PRML decoder is the decoder with two blocks of trellis diagram one of which is without branches of "0" and the other one is without the branches of "1". Decoding is performed by comparing the outputs of two blocks. The decoding error is likely to occur when the difference of two outputs is very small and the hardware implementation is not precise due to mismatching. The proposed idea is to increase the discrimination margin for the output "0" and "1" by amplifying the symbol error while the larger path metrics are saturated. To show the performance improvement of decoding with the proposed idea, simulation results are included

Out-Of-Bounds (OOB) is one of the most powerful vulnerabilities in heap memory. The OOB vulnerability allows an attacker to exploit unauthorized access to confidential information by tricking the length of the array and reading or writing memory of that length. In this paper, we propose a method to automatically detect OOB vulnerabilities in heap memory using dynamic symbol execution and shadow memory table. First, a shadow memory table is constructed by hooking heap memory allocation and release function. Then, when a memory access occurs, it is judged whether OOB can occur by referencing the shadow memory, and a test case for causing a crash is automatically generated if there is a possibility of occurrence. Using the proposed method, if a weak block search is successful, it is possible to generate a test case that induces an OOB. In addition, unlike traditional dynamic symbol execution, exploitation of vulnerabilities is possible without setting clear target points.

The performance of turbo-like codes highly depends on their frame size and thus, the bit error rate performance of turbo-like codes can be improved by increasing the frame size. Unfortunately, increasing the frame size of channel codes induces some drawbacks such as the increase of not only encoding and decoding complexity but also transmission and decoding latencies. On the other hand, a faster than Nyquist (FTN) transmission causes intentional inter-symbol interference (ISI) and thus, induces some correlation among the transmission symbols. In this paper, we propose an FTN transmission with multiple channel codes. By exploiting the correlation among the modulated symbols, multiple code frames can be regarded as a code frame with a lager frame size. Due to the inherent parallel encoding scheme of proposed scheme, parallel decoding can be easily implemented.

The transmitted acoustic signals are severely influenced by multiply reflected signals from boundaries, such as sea surface and bottom in the shallow water. Very large reflection signals from boundaries cause inter-symbol interference so that the performance of the underwater acoustic communication is degraded. Usually, the waveform shaping filters are used to prevent the reflected signals under this kind of acoustic channel. Especially, the raised cosine filter is widely used, which can also be used to restrict the bandwidth of the transmitted signal. In this study, we evaluate the raised cosine filter for image data transmission in the shallow water, and propose a new modified raised cosine filter. The QPSK (Quadrature Phase Shift Keying) system is used for the underwater acoustic communication simulations with different distances and symbol rates. As a result, the bit error rate was reduced from the minimum 1.0 % to the maximum 32 %.

This paper proposes an alternate time-switched space-frequency block coding transmission technique for orthogonal frequency division modulation systems. There are two antennas in the transmitter but it still has only a baseband and RF and a switch that alternates between the antennas at every symbol timing. Alternating transmit symbols result in zeros that make maximal ratio receive combining possible in the receiver. Simulation results show that it provides better performance than the traditional algorithm at the expense of one additional antenna.

We compute explicitly the matrix represented by the Toeplitz operator on the Hardy space over a smoothly finitely connected bounded domain in the plane with respect to special orthonormal bases consisting of the classical kernel functions for the space of square integrable functions and for the Hardy space. The Fourier coefficients of the symbol of the Toeplitz operator are obtained from zeroth row vectors and zeroth column vectors of the matrix. And we also find some condition for the product of two Toeplitz operators to be a Toeplitz operator in terms of matrices.
