This study was conducted to find out the difference in judgment of murder cases by participants' generation according to the type of murder. 196 adults in their 20s and older were randomly assigned to one of the scenarios of parricide, filicide, and murder, then responded to the judgment(ex. judgment of the perpetrator, degree of deviation from social norms, and judgment of victim responsibility). Finally, 128 responses were used in the analysis. As a result, it was found that the main effect of the murder type and the interaction effect of the generation and the murder type were not shown in all dependent variables. However, the difference between generations was statistically significant in the judgment of the perpetrator (e.g., perpetrator blame, perpetrator responsibility, intentional crime, etc.), indicating that millennials made unfavorable judgments to the perpetrator. Especially, in the case of parricide, it was found that millennials made unfavorable judgments to perpetrators than older generations. Also, it was found that the participants of the older generation tended to make unfavorable judgments toward the perpetrator of murder rather than the perpetrator of parricide. Finally, based on these results, this study proposed the need to reconsider the 'victim of survivors' factor, which is considered as a weighing of an offense for special sentencing factors.

In order to establish an autonomous driving environment, it is necessary to study traffic safety and demand prediction by analyzing information generated from the transportation infrastructure beyond relying on sensors by the vehicle itself. In this paper, we propose a real-time traffic information generation method using sensor convergence technology of transportation infrastructure. The proposed method uses sensors such as cameras and radars installed in the transportation infrastructure to generate information such as crosswalk pedestrian presence or absence, crosswalk pause judgment, distance to stop line, queue, head distance, and car distance according to each characteristic. create information An experiment was conducted by comparing the proposed method with the drone measurement result by establishing a demonstration environment. As a result of the experiment, it was confirmed that it was possible to recognize pedestrians at crosswalks and the judgment of a pause in front of a crosswalk, and most data such as distance to the stop line and queues showed more than 95% accuracy, so it was judged to be usable.

The present study examined the relations between physical attractiveness and likability and we also investigated whether these variable's effects differ depending on generation (young and middle-aged) × evaluator gender (male and female) × target gender (male and female). Second, when assessing these variables, we figured out whether evaluators more preferred 'the same-sex preference' than 'the opposite-sex preference'. To that end, 120 college students participated in the 3D program to sample their ideal looks and bodies. Then, another 240 people (60 young men and women each, 60 middle-aged men and women each) evaluated the physical attractiveness, likeability, relationship preference, and personality of the sample. The result is that physical attractiveness is a positively related to likability. There were evaluator gender and target gender differences in the judgment of physical attractiveness, but there were generation and target gender differences in the judgment of likability. Lastly, the effect based on target-maker gender was different for evaluator gender in each factor evaluation. These results were discussed from the evolutionary and sociocultural perspectives on physical attractiveness.

The autoreclosing is applied to power system for maintaining system stability and continuity of supply. Developments on distributed generation(DG) grows significantly by environmental issues and economical issues. If the DG is connected to distribution system, the DG influences the technical aspects such as power quality, protection and stability. It causes the challenges to protection, especially to reclosing. In order to achieve reliability and safety of the distribution system, the rules and guidelines suggest that the DG units should be rapidly disconnected from the network before the reclosing. If the DG is disconnected whenever the fault occurs, it cannot be utilized effectively. This paper presents the adaptive reclosing algorithm considering the DG. The algorithm consists of angle oscillation's judgment, EEEAC(Emergency Expanded Equal-Area Criterion), calculation of optimal reclosing time and re-connection algorithm. The simulation is implemented for the DG technology by using EMTP MODELS. The simulation results show that the transient stability is maintained and the DG is protected against disturbance.

Autoreclosing techniques have been used in power systems to maintain system stability and continuity of supply. Environmental and economical issues have driven significant increases in the development of distributed generation (DG). DG connected to distribution systems, however, may impose negative influences with respect to power quality, protection, and stability, because DG can cause some challenges to protection, especially to reclosing. For this reason, in order to improve the reliability and safety of the distribution system, the rules and guidelines suggest that the DG system needs to be rapidly disconnected from the system before reclosing. We present, in this paper, an adaptive reclosing algorithm considering the DG. The algorithm consists of an angle oscillation's judgment, the emergency extended equal-area criterion (EEEAC), the calculation of an optimal reclosing time, and a reconnection algorithm. Our simulation results for three different DG technologies with Electromagnetic Transient Program (EMTP) indicate that we can maintain transient stability while the DG is protected against disturbances.

Purpose - This study aims to examine differences in donation behavior as surrogates of prosocial consumption behavior among three generation types. Further, it attempts to examine the moderator roles that affect donation behavior influenced by the difference in generations. Research design, data, and methodology - This study used the statistical ANOVA technique to examine generational difference. Surveys were structured differently by ages, as 20th, 30th, 40th, 50th, 60th, and 70th to classify generations into each group. A survey to measure the psychological distance was performed to identify whether the respondents intended to donate to a domestic or overseas target. Results - First, subjective judgment of psychological distance has no effect on objective donation behavior. Second, though the result of the relationship with moral identity is not statistically significant, it provides evidence that a higher moral identity level possesses more donation behavior. Further, groups with higher symbolization tend to donate more than the others. This was especially evident among the young and baby boomer generation. Conclusion - This empirical study suggests that marketers need to differentiate the market segment of the baby-boomer generation with high purchasing power of prosocial consumption.

This paper presents a new mode of expressing a 3D assembly work for creating a 3D CG animation without judgment by human from minimal required information. In the field of manufacturing, there are favorable movements in the utilization of 3D CAD for 3D simulation to shorten lead time for product development and pre-production. But simulating an assembly work has troubles to need huge quantity of manually input data. This paper discusses what minimal necessary information for creating 3D CG animations of assembly works is, focusing on the features of assembly works. Furthermore, a new mode of expressing a 3D assembly work is proposed as "state/change transition diagrams" (SCTD), which express arbitrary scenes in an assembly work as "state" and describe a sequential assembly work with "state" and "change", and the outline of its stepwise generation algorithm is also described. SCTD can be converted to a 3D CG animation of an assembly work without judgment by human. This paper focuses on the creating 3D CG animation of assembly works which workers use only their both hands.
