Purpose: Focusing on Supreme Court precedents, we intend to establish criteria for judging research misconduct. Research design, data and methodology: In addition, I would like to propose the criteria for judging research misconduct by the KODISA, which applies the court's standards well in practice, and guidelines for preventing research misconduct. Research design, data and methodology: After classifying the case of research misconduct into six cases, the court's judgment and practical application will be reviewed. Results: First, research misconduct that has passed the disciplinary prescription can be punished. This is because the state of illegality continues to this day. Second, even if there were no punishment regulations at the time of research misconduct, it can be retroactively punished with the current punishment regulations. This is because research ethics is a universal and common standard and does not change. Third, if there is a fact that infringes on intellectual property rights, it is presumed unwritten intentions. Therefore, the act of taking and using the work of another person without permission or proper citation procedure, even if it is unintentional and for the public interest, is a research misconduct. Fourth, if there is an inappropriate citation notation, the intention of research misconduct is presumed. It is the judgment of the court that even if a quotation is marked, if it is incomplete, it is recognized as plagiarism. Fifth, if the author uses the work of another person without proper source indication, it is plagiarism even if the other person who owns the copyright agrees to it. The understanding or consent of some parties does not justify research misconduct in violation of public trust. Sixth, it is a research misconduct to create a new work without citations for one's previous work. In addition, even if there is a citation, if the subsequent writing is not original, it is a research misconduct. Conclusions: Academia should clarify the scope of research misconduct by referring to the Research Ethics Regulations of KODISA, and deal with research results that lack the value as creative works similar to those of research misconduct.

오류 정정부호의 일종인 터보 코드는 우수한 BER 성능을 얻기 위하여 동일한 복호 과정을 반복 수행해야 하므로 긴 복호시간을 필요로 한다. 따라서 복호시간을 줄이기 위하여 병렬처리를 이용할 수 있는데, 이 경우, 추가 버퍼를 필요로 하는 메모리 경합이 있을 수 있다. QPP 인터리버는 이러한 메모리 경합을 피하기 위하여 제안되었으나, double flow 복호 기법과 함께 사용하여 복호기를 구성할 경우 여전히 메모리 경합이 발생할 가능성이 있다. 본 논문에서는 double-flow 기법을 이용한 복호에서 메모리 충돌을 피할 수 있는 even-odd cross mapping 기법을 제안한다. 이 방법은 QPP 인터리버의 주소 생성 특성을 사용하며, 복호 모듈과 LLR 메모리 블록 간의 인터리빙 회로 구현에 사용될 수 있다. Double flow 기법과 제안한 방법을 적용하여 복호기를 구현하고, 이를 기존의 MDF 기법에 의한 구현과 비교하였을 때, 전체 면적은 약 8% 증가하지만, 복호시간을 최대 약 32% 줄일 수 있다.

This study was carried out to determine the optimum size and number of farm machines for various sizes of land coverage of the cooperative farm machinery utilization systems in Korea-namely Saemaul Mechanized Farming Group (SMFG). Fifty-one SMFG were selected from 8 counties in Chonnam province, and ownership, operation and management of farm machinery were surveyed. Annual covered area, cost and the break-even-point area of farm machinery were analyzed on the bases of the surveyed data and the present governmental subsidy policy, and then the optimum level of farm machinery ownership was determined. The results are summarized as follows: 1. The break-even-point areas of the tractors of 22-23ps, 28ps and 47-50ps were estimated as 12.1ha, 15.3ha and 21.6ha, respectively. The optimum size of a tractor for land sizes of 10-20ha, 20-30ha, and 30-40ha were estimated as 22-23ps, 28ps, and 47-50ps, respectively. 2. The break-even-point area of a rice transplanter was estimated as 3.3ha. The optimum numbers of rice transplanter for land sizes of 10-20ha, 20-30ha, and 30-40ha were estimated as 2,3, and 4, respectively. 3. The break-even-point areas of a speed sprayer (attached on power tiller) and a power sprayer were estimated as 114.6ha and 15.3ha, respectively. The optimum numbers of power sprayer for land sizes of 10-20ha, 20-30ha, and 30-40ha were estimated as 2,3 and 4, respectively. A speed sprayer is desirable for an area of more than 30ha coverage. 4. The break-even-point area of a combine was estimated as 10.7ha. The optimum numbers of combine for land sizes of 10-20ha, 20-30ha, and 30-40ha were estimated as 1,2, and 3, respectively.

In this paper, we propose the new hardware architecture which implements the stereo matching algorithm using the dynamic programming method. The dynamic programming method is used in finding the corresponding pixels between the left image and the right image. The proposed MOEPE(Merged Odd-Even PE) architecture operates in the systolic manner and finds the disparities from the intensities of the pixels on the epipolar line. The number of PEs used in the MOEPE architecture is the number of the range constraint, which reduced the number of the necessary PEs dramatically compared to the traditional method which uses the PEs with the number of pixels on the epipolar line. For the normal method by 25 times. The proposed architecture is modeled with the VHDL code and simulated by the SYNOPSYS tool.

In this study, applied to the industrial water service, it is verified feasibility of break-even analysis method which has not been introduced in Korea. The On-san water pipeline of 7.1km among the Ul-san industrial water service is selected and the optimal replacement time calculated by break-even analysis method is year 2033 to 2044 which will be 53 to 67 years since the pipes were buried. If indirect cost such as the value of lost water and traffic disruption, service interruption, etc. is calculated as 30 and 100% of the direct cost, the financially optimum replacement time is advanced 3 to 9 years. These ways present rational criteria to establish long-term plan for budget and to execute the limited budget efficiently.

Broadcasting is one of the most important communication primitives used in multiprocessor networks. In this letter, we demonstrate that the broadcasting algorithm proposed by Madabhushi and others is incorrect. We introduce efficient one-to-all broadcasting schemes of even networks for one-port and all-port models. The broadcasting time of the one-port model is 2d-3 and that of the all-port model is d-1. The total time steps taken by the proposed algorithms are optimal.

A method for the dynamical analysis of FE discretized uncertain linear and nonlinear structures is presented. This method is based on the moment equation approach, for which the differential equations governing the response first and second-order statistical moments must be solved. It is shown that they require the cross-moments between the response and the random variables characterizing the structural uncertainties, whose governing equations determine an infinite hierarchy. As a consequence, a closure scheme must be applied even if the structure is linear. In this sense the proposed approach is approximated even for the linear system. For nonlinear systems the closure schemes are also necessary in order to treat the nonlinearities. The complete set of equations obtained by this procedure is shown to be linear if the structure is linear. The application of this procedure to some simple examples has shown its high level of accuracy, if compared with other classical approaches, such as the perturbation method, even for low levels of closures.

Inverse Chebyshev function can realize the same order of Chebyshev function nuder the same specification. In general, inverse Chebyshev function has the preferable characteristics in terms of the delay characteristics and the time-domain performances compare with Chebyshev function. However, for the even order n, inverse Chebyshev function does not realize in the doubly-terminated ladder network which has preferable sensitivity characteristics because of the finite value at ${\omega}={\infty}$. In this paper, the modified inverse Chebyshev function with $\mid$H($j^{\infty}$$\mid$=0 s proposed to realize the passive doubly-terminated ladder network for the n even or odd. The modified inverse Chebyshev function characteristics ars studied in the frequency and time domain, and then, realize the passive doubly-terminated ladder network.

This paper deals with the economic analysis of domestic fuel cell vehicles considering subsidy and hydrogen price in 2015 and 2025. We selected TFCV (Tucson fuel cell vehicle) and TDV (Tucson diesel vehicle) to identify the economic feasibility of fuel cell vehicles compared with conventional internal combustion engine vehicles. We made some sensitivity analysis by changing input factors such as the size of the subsidy, the hydrogen price and the discount rate. Also, we made a break-even point analysis on hydrogen prices that equalize the economic feasibility of TFCV and TDV in 2025. As a result, TFCV is not economical in 2015 due to the relatively high prices of hydrogen and vehicles. If the sale prices of TFCV are 30,000,000 won and 35,000,000 won in 2025, then the break-even points of hydrogen prices are equal to 7,483 won/kg and 5,043 won/kg.
