Recently, there has been an increase in the research and development of automated vehicles worldwide. Research focused on automated vehicles in Korea is steadily progressing as a national R&D project. Since automated driving technology comprises diverse technology fields, it is necessary to identify the current position of the research. In this study, we propose a methodology for analyzing research trends using the NTIS data. In addition, we review the effectiveness of the currently developed research trend methodology by deriving primary keywords and major topics using the proposed method. We expect that the methodology developed in this study can be applied to identify and analyze future automated vehicle research trends.

The purpose of this study based on descriptive research is to examine the influences on the self-regulated learning ability due to nursing students' achievement-goal and to make sure mediating effect of autonomous support of professor. A convenience sample of 294 nursing students were recruited from a college in C province from April to May, 2018. Data are analyzed using SPSS/WIN 21.0 program. As a result, it is turned out that there are positive correlation between mastery goal, performance approach goal, self-regulated learning ability and autonomous support of professor. In the Sobel test results, autonomous support of professor had a partial mediating effect between mastery goal and self-regulated learning ability(Z=3.922, p<.001). So, a new teaching method should be developed through the convergence of related factors of self - regulated learning ability.

In this study, We tried to investigate the relationship between the Caregiver's Autonomy of duty and the Their innovation action at the present situation of awareness diffusion of caregiver's job autonomy and rapid aging increasing. We analyzed the factors effected to the innovative action by the caregiver's job autonomy and demographic factor, to the caregivers who work in Seoul. As a result of the analysis, it was found the factors that effect to innovation action statistically and significantly are job autonomy, work schedule, decision-making, methodology, age, education, type of facility, scale of facility and job title. In other words, the organization tries to invest enough job autonomy to caregiver in their environment and the organizational culture tries to encourage new idea is induct positive effect to the innovative action. In this regards, the principal requires ability to create environment that the caregivers can suggest new idea, and develop the management strategy to improve caregiver's job autonomy.

Autonomous vehicles using V2X can drive safely information on areas outside the sensor coverage of autonomous vehicles conventional autonomous vehicles. As V2X technology has emerged as a key component of autonomous vehicles, research on V2X security is actively underway research on risk analysis due to failure of V2X communication is insufficient. In this paper, the service scenario and function of autonomous driving system V2X were derived by presenting the intersection scenario of the autonomous vehicle, the malfunction was defined by analyzing the hazard of V2X. he ISO26262 Part3 process was used to analyze the risk of malfunction of autonomous vehicle V2X. In addition, a fault injection scenario was presented to verify the fail-safe of the simulation-based intersection scenario.

This study investigated empirically the structural relationship of golf participants' basic psychological needs, exercise emotion, and exercise-adherence behavior. Using two-hundred thirty questionnaires, the results were as follows. First, golf participants' autonomy, competence, and relatedness had a significant impact on the positive emotions. On the other hand, only competence lowered the negative emotions, and the other variables did not have a significant impact. Second, golf participants' autonomy, competence, and relatedness increased the exercise-adherence behavior. Third, golf participants' positive emotion increased the exercise-adherence behavior but a negative emotion decreased it. In terms of the indirect effect, golf participants' autonomy, competence, and relatedness influenced the exercise-adherence behavior, which was mediated by exercise emotion. This study is useful to sports participants interested in real value and a happy life through exercise-adherence behavior.

Since 2021, government departments have been promoting Automated Driving Technology Development and Innovation Project as national research and development(R&D) project. The automated vehicles and service technologies developed as part of these projects are planned to be subsequently provided to the public at the selected Living Lab City. Therefore, it is important to determine a spatial area and operation section that enables safe and stable automated driving, depending on the purpose and characteristics of the target service. In this study, the static Operational Design Domain(ODD) elements for Level 4 automated driving services were reclassified by reviewing previously published papers and related literature surveys and investigating field data. Spatial analysis techniques were used to consider the reclassified ODD elements for level 4 in the real area of level 3 automated driving services because it is important to reflect the spatial factors affecting safety related to real automated driving technologies and services. Consequently, a total of six driving mode changes(disengagement) were derived through spatial information analysis techniques, and the factors affecting the safety of automated driving were crosswalk, traffic light, intersection, bicycle road, pocket lane, caution sign, and median strip. This spatial factor analysis method is expected to be useful for determining special areas for the automated driving service.

무인자율항체는 자동차, 선박, 잠수함과 같이 인간에 의해 직접 조종되는 유인항체에 인간의 역할을 대신할 수 있는 지능시스템을 배치하여 전체적 혹은 부분적으로 무인화한 이동체를 말한다. 무인자율항체에서 사용되는 소프트웨어는 인식, 사고, 행위와 같은 인간의 지적능력을 내포한 인공지능시스템이어야 한다. 자율무인잠수정, 자율운항선박과 같은 저속무인자율항체는 무인항공기나 무인차량과 같이 빠른 판단과 제어가 요구되는 지능제어시스템과는 다른 특성을 가진다. 저속무인자율항체에서 가장 주목되는 특성은 주위 환경 변화속도와 운항속도에 따른 긴박감의 차이이다. 고속자율항체에서는 제어시스템의 처리속도에, 저속자율항체에서는 제어시스템의 신뢰성에 비중을 둔다. 본 연구에서는 이와 같은 저속무인자율항체의 특성과 기능별 독립성 보장, 반응형 및 인식형 인공지능 기법의 융화 극대화에 촛점을 맞춘 RVC(Reactive Layer-Virtual World-Congnitive Layer) 지능시스템 모델을 제안한다.

This study examined the factors affecting the sexual autonomy of female university students to provide the basic data for developing an intervention program for sex education. The data was collected from 322 female college students and analyzed with a t-test and multiple regression using the SPSS 21.0 program. The significant factors of sexual autonomy were intercourse experience (${\beta}=0.115$, p=.040), sex knowledge (${\beta}=0.118$, p=.028), permissiveness of sexual violence (${\beta}=-0.290$, p<.001), and the perception of unwed pregnancy (${\beta}=-0.104$, p=.048). These factors explained 21.7% of the variance in sexual autonomy. In conclusion, there is a need to develop a sex education program to increase sexual autonomy considering the factors affecting sexual autonomy.

The purpose of this study is to improve the social acceptance of AVs by analyzing the citizen's perception using an emotional analysis technique which belongs to a type of text mining. The source of the data is originated from 3 year accumulated internet articles and comments on AV from 164 newspapers and Naver. According to the study results, there exists a positive perception on AVs, although negative ones are more frequent than the positive. Also most of people take neutral position on AV due to the unfamiliarity and lack of experience on AVs And these problems needs to be responded before AV's commercialization through continuous analyses on the perception and social acceptance.

Autonomous vehicles can be exposed to severe danger when failure occurs in any of its components. For this reason many countries are making efforts on the legislative issue how to objectively evaluate failure safety of an autonomous vehicle when such a vehicle is commercially available to a customer in the near future. In level-3 automation, a driver must take over the control of his vehicle when failure occurs, and the driver's controllability must be secured for escape from the imminent danger. In this paper, quantitative methods have been developed for evaluating failure safety of the level-3 autonomous vehicle, and they were validated by simulation. And also, we confirmed that the proposed evaluation method can quantitatively evaluate the failure safety.
