In this paper, system dynamics considering dynamics and time was examined to study the changes in system structure according to reinforcement (policy intervention) of regulation and punishment for fishing boats, and the strategizing directions were analyzed. Until now, regulations and punishments on fishing boats have been conducted temporarily and short-term as a precautionary measure to prevent accidents and imposed penalties. However, due to various anomalous side effects, the expected results were not achieved, negligent accidents occurred constantly, and follow-up measures were repeated. Resultantly, the regulation and punishment of fishing boats is a reinforced safety standard, and there is a necessity to improve facilities, equipment, and industry, and develop technology (including time delay) to prevent accidents. However, as the negative (illegal) activities continue without immediate and significant resistance, the safety blind spot for accident prevention cannot be minimized. Thus, policy intervention based on linear thinking without sufficiently considering variables of the dynamic mechanism and time can distort the basic values pursued by the policy. For the regulation and punishment of fishing boats, a strategy to supplement the mechanism should be prepared prior to the preparation of reinforced safety standards. Improvement and development of related technologies, mandatory training hours for anglers, fishing industry, and related organizations, proposal of specific action plan for Fishing Management and Promotion Act for growing fishing-related industries.

The Purpose of this study is to analyze the mechanism of permanent death and playing aspects in Rogue-like games. The death in digital game is not only punishment of failure, but reward for player's growth. However the mechanism of permanent death which does not allow to resurrect is critical penalty for players and causes play-cycle with high anxiety. In the mechanism of permanent death, players do critical play to evade the death. But when they replay the game they modify their unethical choices to build alternative game world. Through the mechanism of permanent death which demands critical and alternative play, it could be possible to find the way to design games with serious choice.

The 5G Core Network (5GC) is an essential part of the mobile communication network, but its security protection strategy based on the boundary construction is difficult to ensure the security inside the network. For example, the Network Function (NF) mutual authentication mechanism that relies on the transport layer security mechanism and OAuth2.0's Client Credentials cannot identify the hijacked NF. To address this problem, this paper proposes a trust model for 5GC based on NF interaction behavior to identify malicious NFs and improve the inherent security of 5GC. First, based on the interaction behavior and context awareness of NF, the trust between NFs is quantified through the frequency ratio of interaction behavior and the success rate of interaction behavior. Second, introduce trust transmit to make NF comprehensively refer to the trust evaluation results of other NFs. Last, classify the possible malicious behavior of NF and define the corresponding punishment mechanism. The experimental results show that the trust value of NFs converges to stable values, and the proposed trust model can effectively evaluate the trustworthiness of NFs and quickly and accurately identify different types of malicious NFs.

Due to the characteristics of an ad hoc network without a control center, self-organization, and flexible topology, the trust evaluation of the nodes in the network is extremely difficult. Based on the analysis of ad hoc networks and the blockchain technology, a blockchain-based node-level trust evaluation model is proposed. The concepts of the node trust degree of the HASH list on the blockchain and the perfect reward and punishment mechanism are adopted to construct the node trust evaluation model of the ad hoc network. According to the needs of different applications the network security level can be dynamically adjusted through changes in the trust threshold. The simulation experiments demonstrate that ad-hoc on-demand distance vector(AODV) Routing protocol based on this model of multicast-AODV(MAODV) routing protocol shows a significant improvement in security compared with the traditional AODV and on-demand multipath distance vector(AOMDV) routing protocols.

Criminal media such as dramas and movies are growing in popularity. However, the effects of criminal media as well as its psychological mechanism are not clearly examined. Based on social learning theory (Bandura, 1978), past studies showed that arrest and punishment to the criminal in media have a suppressing effect. The present research examined the ironic possibility that media coverage of punishment could increase the audience's criminal intention and proposed the mediating role of counterfactual thinking in the effect. We hypothesized that when punishment was depicted as accidental rather than unavoidable in media coverage, perceived high mutability and counterfactuals focusing on the accidental factors could clarify the ways to commit the crime without being caught and subsequently increase future criminal intention. In this study, 95 college students read a story of plagiarizing either no, accidental, or inevitable punishment, and later asked to report their intention to plagiarize. An ANCOVA with participants' own history of plagiarism as a covariate found that the intention of plagiarism in future was significantly different. The results showed that the intention of plagiarism in the accidental punishment condition was higher than that in the inevitable punishment condition. Further, the intention of plagiarism in the accidental punishment condition was the same level with non-punishment condition. The findings suggest that whether criminals are caught or not is not enough to reduce criminal intentions of audience, but how criminals are caught matters.

The optimal price strategy selection of two bounded rational cognitive mobile virtual network operators (MVNOs) in a duopoly spectrum sharing market is investigated. The bounded rational operators dynamically compete to sell the leased spectrum to secondary users in order to maximize their profits. Meanwhile, the secondary users' heterogeneous preferences to rate and price are taken into consideration. The evolutionary game theory (EGT) is employed to model the dynamic price strategy selection of the MVNOs taking into account the response of the secondary users. The behavior dynamics and the evolutionary stable strategy (ESS) of the operators are derived via replicated dynamics. Furthermore, a reward and punishment mechanism is developed to optimize the performance of the operators. Numerical results show that the proposed evolutionary algorithm is convergent to the ESS, and the incentive mechanism increases the profits of the operators. It may provide some insight about the optimal price strategy selection for MVNOs in the next generation cognitive wireless networks.

Independence and impartiality are the operating core of an arbitration disciplinary mechanism. Due to many factors, illegalities and improper acts in arbitration cases are facts of life in our country, and have greatly damaged the credibility of arbitration. It is necessary for us to perfect the operating mechanism of arbitration discipline from the four pluralistic progressive aspects of disciplining the cause externalization, disciplining the subject duality, the quasi-judicature of disciplinary procedures and the disciplining measures so that the populace can experience fairness and justice in every case. We should perfect the supporting measures such as the strict selection conditions and procedures of arbitrators, improving the quality of the arbitrator team, exploring the management mechanisms and strengthening the evaluation dynamic. An examination is a general investigation and evaluation so as to provide encouragement for being continually engaged as arbitrators, but it does not provide an objective basis of arbitration discipline. It is urgent to perfect the arbitration guarantee system on the basis of meeting the material needs of the arbitrators so as to enhance the sense of professional rank and honour of arbitration.

The Movie, A Werewolf Boy, describes metaphorically the hidden desire of female audience. The majority of stories about wolves contains fear of wolves inherited by and learned through human history struggling with the nature. They also shows punishment and reward toward wolves as a cultural symbol of evil. This study focuses on analyzing wolves as a metaphor of hidden original desire rather than as a subject of fear and punishment. Soon-Hee's experience with a wolf-boy in her period of puberty and her remembering the experience in her old age expresses her original sexual desire. The movie, A Werewolf boy does not directly deal with sexual content. However, SU-NI's growth through the interaction with the wolf-boy informs us Freudian theory of sex and the mechanism of sexual desire and its repression or realization. Brun Bettelheim's "Little Red Riding Hood" was used to analyze Soon-hee's desire during her puberty and Clarissa Estes's "Women Who Run with the Wolves" were used to explore SU-NI's wildness forgotten in her elderlyhood. This study shows in the process of wolf boy's transformation from biological being into social being awakened the hidden and original desire of woman.

Voters' negative evaluations of government performance lower their trust in government, which functions as the reward and punishment for the government. Trust in government thus serves to promote political accountability of the representative government. However, voters build their confidence toward the party government where the ruling party is responsible for the performance. Considering this partisan nature, we empirically examine that the influence of voters' performance evaluations on governmental trust is conditional on their party identifications. While higher perceptions of political/social conflict and increasing negative evaluations of government policies and economic performance are associated with the lower level of confidence in government, the relationship is contrasted between different party identifiers. For supporters of the ruling party in 2020, the negative evaluations of government performance are not likely to reduce trust in government a lot. On the contrary, those who identify with the main opposition party show the most prominent effect of negative evaluations on their distrust in government. This study demonstrates that trust in government is affected by voters' partisan preferences, not entirely by evaluations of government performance. Such a distortion of the reward and sanction function of governmental trust might lead to the weakening of the accountability mechanism in representative democracy.

Drug dependence deals a heavy socioeconomic burden to the society. For adolescents, the damage from drug dependence is greater than adults considering their higher susceptibility to drug effect and increasing chance for violence leading to criminal punishment process. Habitual drug use depends on genetic and environmental factors and the complex interactions between the two. Mammalian model systems have been useful in understanding the neurochemical and cellular impacts of abused drugs on specific regions of the brain, and in identifying the molecular targets of drugs. More elucidation is required whether biological effects of drugs actually cause the habitual dependence at the cellular level. Although there is much insight available on the nature of drug abuse problems, none of the systems designed to help drug dependent individuals is efficient in screening functional ingredients of the drug, and thus resulting in the failure of helping drug dependent individuals recover from drug dependence. Alternative model systems draw the attention of researchers, such as the invertebrate model systems of nematodes (Caenorhabditis elegans) and fruit flies (Drosophila melanogaster). These models should provide new insight into the mechanisms leading to the behavior of drug users (even functional studies analyzing molecular mechanism), and screening useful components to help remove drug dependence among drug users. The relatively simple anatomy and gene expression of the invertebrate model systems should enable researchers to coordinate current knowledge on drug abuse. Furthermore, the invertebrate model systems should facilitate advance in experiments on the susceptibility of specific genetic backgrounds and the interaction between genetic factors to drug dependence.
