Technology that cannot be excluded from 4th industry is self-driving sector. The self-driving sector can be seen as a key set of technologies in the fourth industry, especially in the DB sector is getting more and more popular as a business. The DB, which was previously produced and managed in two dimensions, is now evolving into three dimensions. Among the data obtained by Mobile Mapping System () to produce the HD MAP necessary for self-driving, Point Cloud, which is LiDAR data, is used as a DB because it contains accurate location information. However, at present, it is not widely used as a base data for 3D modeling in addition to HD MAP production. In this study, MMS Point Cloud was used to extract facilities around the road and to overlay the location to expand the usability of Point Cloud. Building utility poles and communication poles DB from Point Cloud and comparing road name address base and location, it is believed that the accuracy of the location of the facility DB extracted from Point Cloud is also higher than the basic road name address of the road, It is necessary to study the expansion of the facility field sufficiently.

This paper investigates the effects of transformational leadership and transactional leadership on the creativity of members in R&D organizations. We also analyze the leadership mechanism and the influence of effective environment by using team climate as a mediator and using adhocracy and hierarchy organizational culture as moderator. Data were collected through surveys of Korean Public Research Institutes conducting mainly basic science and applied sciences. 327 valid samples were tested using a structural equation model (SEM). Empirical results confirm that transactional leadership exhibits stronger direct effect on the creativity than transformational leadership. However, in indirect effects mediated by creative team climate, transformational leadership is found to be stronger than transactional leadership. It may reflect the characteristics of R&D organization. Also, through the verification of the moderating effect of the organizational culture, the adhocracy organizational culture appears to improve the creativity and the hierarchical organizational culture appears to inhibit the creativity. It is confirmed that the influence of organizational culture is statistically significant in R&D organizations with strong autonomy and independence. It is suggested that the leadership on the creativity of the members in the R&D organization may be indirect in the context of the team and the organization as well as the direct effects according to the type.

Data scientists are new knowledge workers representing the knowledge economy era. Knowledge workers perform unstandardized works that solve ambiguity-intensive problems. Therefore, self-leadership, which emphasizes self-motivated, autonomous judgment and execution, significantly influences their work-related outcomes. Even knowledge workers have high occupational commitment, they usually show low organizational commitment. Knowledge workers' intention to leave is also relatively high due to this reason. This study focused on data scientists' self-leadership, predicted that self-leadership would increase an organization's commitment and intention to leave. Based on the trait activation theory(TAT), the author also confirmed how perceived job autonomy enhances self-leadership influences. Results showed that data scientists' self-leadership significantly lowered intention to leave through organizational commitment and this mediating effect was moderated by perceived job autonomy. This study broadened the theoretical understanding the effects of knowledge workers' self-leadership and presented practical implications for managing data scientists.

The purpose of this study is to verify that voting behavior of congressmen can vary depending on the different candidate selection methods of political parties. Specifically, this paper examines whether congressmen elected through a primary tend to deviate from the party line vote in the floor voting, compared to those who did not. As a result, it was founded that congressmen who went through competition of the primary are more likely to defect from the party line vote than who did not. This empirical evidence suggests that if the introduction of the open primary system is further expanded in the future, it may lead to weakening of party cohesion and reinforcing lawmakers' autonomy.

Chemical agents are classified according to their mechanism of toxicity into categories such as nerve agents, choking agents, blood agents, blister agents, etc. Among them, nerve agents cause toxic symptoms by binding with acetylcholinesterase (AChE) in the body, which breaks down neurotransmitters, thus disrupting the autonomic nervous system. In severe cases, this can lead to death, making it a critical chemical agent. Therefore, once it has penetrated into the human body, it is important to detoxify it swiftly. Antidotes used for detoxification include chemical medicines such as pretreatment agents, post-treatment agents, anticonvulsants, and bioscavengers. This review will address the uses, forms, components, and principles of detoxification of nerve agent antidotes and the association with bioscavengers.

For the commercialization For the commercialization of autonomous vehicles (AV), the operational design domain (ODD) of automated driving systems (ADS) is to be clearly defined. A common language and consistent format must be prepared so that AV-related stakeholders can understand ODD at the same level. Therefore, overseas countries are presenting a standardized ODD framework and developing scenarios that can evaluate ADS-specific functions based on ODD. However, ODD includes conditions reflecting the characteristics of each country, such as road environment, weather environment, and traffic environment. Thus, it is necessary to clearly understand the meaning of the items defined overseas and to harmonize them to reflect the specific domestic conditions. Therefore, in this study, domestic optimization of the ODD classification system was performed by analyzing the domestic driving environment based on international standards. The driving environment of currently operating self-driving car test districts (Sangam, Seoul, and Gwangju) was investigated using the developed domestic ODD items. Then, based on the results obtained, the ranges of the ODDs in each test district were determined and compared.
