This paper presents an efficient heuristic algorithm to avoid crosstalk which effects to delay of CMOS digital circuit by downsizing and upsizing of Gate. The proposed algorithm divide into two step, step1 performs downsizing of gate, step2 performs upsizing, so that avoid adjacent aggressor to critical path in series. The proposed algorithm has been verified on LGSynth91 benchmark circuits and Experimental results show an average 8.64% Crosstalk Avoidance effect. This result proved new potential of proposed algorithm.

This paper describes on a software simulator that can be used for an anti-ARM system. The proposed simulator is a valuable tool for investigating the optimum deployment of decoy antennas which are widely using for anti-ARM and calculating the electromagnetic field at the ARM receiver. To verify the effect of decoy antennas, we analyze the field intensity and phase at the receiver. We conduct an analysis of ARM attack in case of using multiple decoy antennas and the proposed simulator can be used to decide the optimum positions of the decoys.

2007년 일본최고 재판소는 히로시마시 폭주족 추방조례사건에 대하여 헌법판단 회피의 이론에 입각한 합헌적 한정해석론에 따라 합헌결정 판결을 내렸다. 이는 기존의 판결내용을 답습한 것에 불과 하였지만 합헌적 한정해석이라는 헌법해석의 방법론에 관한 의미를 한번 되새기는 계기가 된 사건이다. 이 법리에 의한 것으로는 1980년대의 청소년보호조례사건이 유명하다. 이 두 사건은 하나는 공안사건이고 다른 하나는 풍속에 관한 사건이라는 점에서 차이가 있다. 폭주족 추방조례사건은 합헌적 한정해석의 법리가 적용될 여지가 있다고 보이지만 청소년보호조례사건과 같은 풍속에 관한 사건에서는 이 법리를 적용하는 것은 무리라고 생각된다. 왜냐하면 청소년보호조례사건에서는 음행, 난잡한 성행위라는 너무나 막연하고 애매한 개념을 사용하고 있어 형사절차에서의 대 원칙인 죄형법정주의에 위배될 소지가 있으며 성적 자기결정의 자유를 규제할 때에는 이에 따른 필연적인 이유가 존재해야 함에도 그렇지 못하다는 문제점과 일반국민에게 지나친 심리적 위축을 초래할 수 있다는 점에서 위헌논란이 제기되었다. 그럼에도 일본 최고재판소는 이를 합헌적 한정해석의 법리를 원용하여 위헌선언하기를 꺼려온 바 이는 헌법판단회피를 의도적으로 하는 것으로 지나친 사법소극주의적 태도라고 하지 않을 수 없다. 법원은 사건의 중대성이나 위헌상태의 정도 그 파급효과의 범위, 구체적 사건에서 문제가 되고 있는 권리의 성질등을 종합적으로 고려해서 충분히 이유가 있다고 판단되는 경우에는 헌법판단회피의 준칙에 따르지 않아야 하며 헌법판단을 적극적으로 할 수 있다고 해석하는 것이 타당하다고 생각된다.

This study was intended to study how social responsibility of small businesses affected tax avoidance. Specifically, it was intended to verify how social responsibility is influenced by tax psychological factors and how it is related to tax avoidance by making it an economic liability factor, an ethical liability factors. For him, the empirical data were reviewed, the questionnaire was prepared, and the collected data was analyzed using SPSS ver. 22.0 and PROCESS MACRO ver. 3.4. The verification showed that corporate economic and ethical responsibilities affected tax avoidance and that legal responsibility did not affect tax evasion, and that tax psychological factors mediated some of the effects of social responsibility on tax avoidance. Judging from the above results, it is doubtful that the prevention of tax evasion would require tax incentives to offset the costs incurred by an enterprise's economic responsibilities, and to establish a strict tax code to prevent one or two tax evasions from spreading throughout the group. In this study, however, there are limitations that arise from differences between variables omitted from the research model and methods of measuring tax hedges. Therefore, further studies using a wider variety of variables are required in subsequent studies.

This study examines whether firms with tax avoidance of Corporate Social Responsibility(CSR) performance is tempered by the extent firms engage in CEO turnovers. Considering the increasing interest in CSR activities of the firm to secure sustainable growth of national economy, this paper investigates the benefit and cost of CSR activities by combining the agency theory using the firm level data. Prior studies document that investors positively value tax avoidance. The rationale for this finding is that tax avoidance provides cash savings that can be used by firm managers to generate future shareholder wealth. Prior studies also show that investors' valuations are sensitive to the risk of future negative tax outcomes. Assuming that many types of CSR performances are low risk, low yielding uses of firm resources, we posit that higher levels of CSR performance may signal to investors that cash generated via tax avoidance has not been fully used to generate a return sufficient to offset the risk associated with aggressive tax planning strategies. Consistent with this argument, we predict and find that the positive association between CSR performance and tax avoidance is significantly weakened when firms have higher positive levels of CEO turnovers. Further, we predict and find that 'philanthropic' types of CSR activities in particular are associated with investor discounting of tax avoidance. We interpret our results as suggesting the equity market views CSR activities to be ostensibly funded through cash savings generated via tax avoidance.

This study was to examine the differences of Korean and Chinese high school students on classroom goal structure(i.e., mastery, performance-approach, and performance-avoidance), help-seeking behavior(i.e., help-seeking, and help-seeking avoidance), and school engagement(i.e., behavioral, cognitive, and emotional), and to identify the mediating role of help-seeking behavior in the links between classroom goal structure and school engagement. The final samples consisted of 290 Korean and 294 Chinese students in high school. Results were as followed. Firstly, Chinese students had a higher classroom mastery goal structure, classroom performance-avoidance goal structure, help-seeking and emotional engagement than Korean students, whereas Korean students had a higher behavioral engagement than Chinese students. Secondly, for Korean students, help-seeking and help-seeking avoidance mediated between classroom mastery goal structure and school engagement. Moreover, for Korean students, help-seeking avoidance mediated between classroom performance-avoidance goal structure and school engagement. While, for Chinese students, help-seeking and help-seeking avoidance mediated between classroom performance-avoidance goal structure and school engagement. Also, for Chinese students, help-seeking avoidance mediated between classroom mastery goal structure and school engagement. Therefore, help-seeking should be promoted in order to improve students' school engagement, and classroom mastery goal structure need to be created in order to encourage students' help-seeking.

This paper estimates the relative risk aversion coefficients of apple farmers. Two hypothetical situations are designed and two-stage questionnaires are conducted for each situation. A utility function that has constant relative risk aversion was used, and it was assumed that the relative risk aversion coefficients follow a log-normal distribution. To reduce the hypothetical bias, the data was collected from repetitive questions. As a result, the mean and standard deviation of the relative risk aversion coefficients of apple farmers was 10.915 and 7.516, respectively. The relative risk aversion coefficients conditional on a survey response in each category were also measured. These findings can be used as parameters to analyze the effects of risk management tools.

In nowadays, Covid-19 has transformed patterns of consumers' behavior into a non-face-to-face mode. As the patterns of consumption have been digitalized, it has become a daily routine for consumers who perform so-called shadow work, which involves unpaid jobs that they have to do by themselves. In mobile grocery service context, consumers' shadow work could lead to shopping avoidance as well as switching toward other shopping channels. Thus, this study is to examine how consumers' perception of shadow work affect mobile shopping avoidance and switching intention toward other shopping channels. This study collected 283 survey data from online respondents who have experience on subscription services for ordering groceries in online. We also tested our research model by using partial least squares. Based on our results, this study has found that the perception of shadow work had a positive effect on mobile shopping avoidance as well as switching intention. We expect that our findings could contribute to relevant research on shadow work and suggest practical implications for digital platforms dealing with subscription business models
