This study was initiated with the aim of suggesting a further step in the program of literary therapy by revealing the mechanism by which the body heals through the discharge of neural network codes. Sentence is encoded as neural signals in our body as it is being read. If the neural networks in the human body are activated and created, the code in which the neural networks are encoded is a code composed of sentences. That is, Sentence is a code. And if the Sentence connects to the human body again and activates the human neural networks, it can be said that Sentence is encoded. At this time, the relation of "neural network codes = Sentence codes" is established. In other words, human narrative and literary narratives are the mediums that convey the same kinds of neural network codes. Cho Ji-Hoon's Poem "White Night" draws sadness through the path of loneliness in 1strophe. Through the Sentence of Loneliness, it activates neural network codes of sadness. 2strophe for the 'pure white snow' is the encoding of the Sentence. In 3strophe, the sentence for 'sadness' is encoded. This flow causes a healing mechanism in this Poem, because the neural network codes about the loneliness, sadness, and eyes of the human body are passed to the other. Here, the other is "White Night". In the future, it is expected that more effective healing results will be obtained if a literary therapy program on the encoding of the sentence of Cho Ji-Hoon's Poem is performed in the future.

표절은 불법이고 피해야 하지만 여전히 빈번하게 발생하고 있다. 특히, 소스코드 표절은 그 특성상 복사가 용이해 다른 저작물보다 더 빈번히 발생한다. 코드 표절을 방지하기 위한 다양한 연구가 있었다. 하지만 앞서 연구된 소스코드 표절 검사 기법을 살펴보면 프로그램이 알고리즘과 데이터 구조로 구성됨에도 불구하고 데이터 구조는 전혀 고려하지 않고 있다. 이 논문에서는 데이터 구조를 고려한 소스코드 표절 검사 기법을 제안한다. 구체적으로 말해서 두 소스코드의 데이터 구조를 트리 집합으로 나타내고, 헝가리안 메소드를 사용해 비교한다. 제안하는 기법의 효용성을 보이기 위해 객체지향 교과목에서 과제 답안으로 제출한 126개의 소스코드를 대상으로 실험하였다. 실험 결과 데이터 구조와 알고리즘을 모두 고려했을 때, 알고리즘만 고려한 경우보다 정확률과 F-measure가 각각 22.6%, 19.3% 향상됨을 보였다.

Most data parallel language compilers are source-to-source translators. Most Compilers of HPF which is recognized as a standard data parallel language convert a parallel program in PHF in a Fortran 77 program inserted message passing primitives. By the way, they currently generate significant amount of ineffective codes in the course of the conversion. Especially, FORALL construct is converted into several DO loops, so loop overhead of these codes is very increased. In this paper, we define and use relation distance vector to keep necessary informations. Then we evaluate and analyze execution time for the codes converted by our method and by PARADIGM method for various array sizes.

In this research a real-time control system was developed without program codings during control system designing procedures. On the Simulink window control system is designed in the form of block diagrams, program codes are produced automatically with the real time workshop package, then C-compiler compiles the program codes. With this automatic real-time program producing mechanism rapid prototyping is realized. To show effectiveness of the proposed system designing scheme a DSP-based DC motor speed control system was constructed and PI and Fuzzy control methods were implemented.

This paper presents the possible effects and restrictions that may arise in the field of industrial construction due to compliance with relevant construction codes and regulations, as well as the ways they can be favorably handled in the design of industrial buildings. Designs should be based primarily on human design factors, while considering the human as the centre of the work environment. Design parameters should be described as a function of both the physical and psychosocial attributes of a person as well as the technical and economical aspects on the design of industrial construction. This paper is an examination of the connection that exists between design law (codes and regulations) and industrial construction. The relevant construction laws and regulations are described, including standards and codes of practice that designing and supervising engineers are obliged to observe. Possible solutions and consequences of development in the production, constructional, and ergonomic field of design are also discussed.

This paper presents a Reynolds equation solver for hydrostatic gas bearings, implemented to run on graphics processing units (GPUs). The original analysis code for the central processing unit (CPU) was modified for the GPU by using the compute unified device architecture (CUDA). The red-black Gauss-Seidel (RBGS) algorithm was employed instead of the original Gauss-Seidel algorithm for the iterative pressure solver, because the latter has data dependency between neighboring nodes. The implemented GPU program was tested on the nVidia GTX580 system and compared to the original CPU program on the AMD Llano system. In the iterative pressure calculation, the implemented GPU program showed 20-100 times faster performance than the original CPU codes. Comparison of the wall-clock times including all of pre/post processing codes showed that the GPU codes still delivered 4-12 times faster performance than the CPU code for our target problem.

The purpose of this paper is to produce color harmony code based on color harmony prototype in terms of environmental color design. This paper proposes ways of categorizing more accurate color harmony prototype through digital image processing by the computer program called the Color Syntax. The method of analysis adopted in this paper is pixel based color image processing. The study suggests color harmony prototype which are categorized by a color harmony angles. These angles represented internal relations between colors. This study describes development processes of color harmony prototype which is a basis for creating color harmony codes. Development processes of color harmony schema consists of color analysis, color codes generation and color selection. Also, how to analyze color images and to chose suitable harmony color codes among various codes are main research issues. As a final result, 109 color harmony codes have been obtained. These code numbers are suggested through rotating 2 color pairs in a 360-degree arc in the same color harmony angles, the codes which is applicable to the color harmony schema previously developed. This color harmony codes will produce better color environment in a sense that it will help designers to maximally reduce their time consumption, and the results of their designs will also be related to the use of proper color for regional environments.

본 논문에서는 심볼릭 링크 공격에 취약한 코드를 정의하고 프로그램 분석 기법을 사용하여 이를 검출하는 방법을 제안한다. 심볼릭 링크 공격을 해결하기 위한 기존의 방법들은 심볼릭 링크 공격을 방어하기 위한 기법들로써 임시 파일에 대한 접근 시 공격이 이루어졌는지에 대한 적절한 검사가 이루어져야 하나, 이를 간과할 경우 공격의 위험에 노출되게 된다. 본 논문에서 제안하는 방법은 심볼릭 링크 공격에 취약한 부분을 자동으로 모두 검출함으로써 프로그래머가 심볼릭 링크 공격을 안전하게 방어할 수 있도록 한다. 제안하는 방법은 취약점 분석을 위해서 기존의 타입 시스템에 새로운 타입 한정자를 추가하고, 추가된 타입 한정자를 고려한 타입 검사를 통해서 심볼릭 링크 공격의 취약점을 식별한다. 제안하는 방법은 자동으로 심볼릭 링크 공격의 취약점을 모두 검출할 수 있기 때문에, 프로그래머가 취약한 것으로 식별된 코드에 대해서만 기존의 방어 기법을 적용하도록 함으로써 프로그램을 전반적으로 검토하거나 수정해야 하는 부담을 줄여준다는 장점을 가진다. 제안하는 방법을 널리 알려진 실용적인 프로그램을 대상으로 실험해 본 결과 전체 fopen() 함수 중 일부만 심볼릭 링크 공격에 취약한 것으로 분석되었으며, 이는 제안한 방법이 프로그래머의 부담을 줄이는데 유용함을 보여준다.

해커들이 자신들이 만든 악성코드의 분석을 어렵게 하기 위하여 코드 난독화 기법을 적용하고 있다. 최근의 난독화 기법은 가상화 난독화 기법을 통해 원래의 코드를 바이트코드로 만들고 가상머신이 이를 실행시키는 방식으로, 실행시키기 전에는 원래의 코드를 알 수가 없다. 프로그램 슬라이싱은 프로그램 분석기술 중 하나로 슬라이싱 기준을 정하고 그와 관련된 문장을 추출해내는 기술이다. 본 논문에서는 슬라이싱 기법을 사용하여 난독화를 해제하는 방법을 제시한다.
