An autonomous car(driverless car, self-driving car, robotic car) is a vehicle that is capable of sensing its environment and navigating without human input. Autonomous cars can detect surroundings using a variety of techniques such as radar, lidar, GPS, odometry, and computer vision. Advanced control systems interpret sensory information to identify appropriate navigation paths, as well as obstacles and relevant signage. Autonomous cars have control systems that are capable of analyzing sensory data to distinguish between different cars on the road, which is very useful in planning a path to the desired destination. An issue tree, also called a logic tree, is a graphical breakdown of a question that dissects it into its different components vertically and that progresses into details as it reads to the right.Issue trees are useful in problem solving to identify the root causes of a problem as well as to identify its potential solutions. They also provide a reference point to see how each piece fits into the whole picture of a problem. Using Issue-Tree menthods, transportation safety policies were developed with autonompus vehicle in mind.

The structure of a mathematics task shapes the aspects of learning of those who solve the task. This study explores the process of understandings on the statistical variability of primary school students. Students were given two problems with different degrees of structuring - a well-structured problem (WSP) and an ill-structured problem (ISP) - and discussed in a group to solve each task. The highest level of development achieved in both cases appeared to be similar. However, when given the ISP, students dynamically proposed ideas and justified the conclusion based on their hypothesis. Furthermore, all students actively participated in solving the ISP until the end whereas some students were marginalized while solving the WSP. This discrepancy results from the difference in the degrees of task structuring.

In this study, we analyzed the change of teacher knowledge through task design in the teacher-researcher community focused on knowledge of students in the area of derivatives application. The following subjects were studied. First, we have analyzed the focus of the discussion related to teacher knowledge of students within the teacher-researcher community. Second, we have analyzed the change of teacher knowledge of students according to the focus. The results of this study are as follows. First, community member' different knowledge of students led the discussion on the task solving paths. The main focus of the discussion was the possibility in inducing responses and motivation. Second, the process of reviewing and evaluating task solving paths and reaching consensus led the improvement of teacher knowledge. Teachers and researchers led changes of teacher knowledge by sharing the knowledge based on previous research and experience, respectively. This ultimately shows the necessity of co-learning between teachers and researchers in teacher education.

The purpose of this study is to survey its characteristics through analyzing brain-wave activity in the scientifically-gifted and general children in the problem-solving process. The subjects of this study were 6 elementary school students, who are attending the institute of education for the gifted belonging to the regional office of education and 6 general children in the same region. The analysis was performed targeting total 12 people. As the task for measuring brain wave is Hanio tower, it is the effective task of researching into the problem-solving process. As the equipment of measuring brain wave is EEG System, it used equipment that was developed in Australia. The analysis of data was minimized noise. As a result of research, the gifted children are excellent in stable level compared to general people in a stable situation with opening the eyes, thereby being able to be known to be high in preparatory level for learning. This can be seen to be indicated as a result that the effect of learning is excellent due to being high in preparatory level for solving problem. Also, even in the process of performing task, the brain-activity level in the gifted children is high, thereby having been able to know that ${\alpha}-wave$ is formed that is significantly high in the regions of frontal lobe and occipital lobe. Accordingly, given developing task that is high in brain activity level of the gifted children, the higher educational effect will be able to be expected.

The possibility of the struggle over copyrighting is increasing with the necessity and expectation of using other works by the developing multimedia technology. In multimedia environment compared with the past, the reproduction of works has some characteristics, such as easy reproduction, the high quality, and easy modification. Also, many composite and interactive works are produced, but there are different characteristics from traditional materials. From free access to information based upon multimedia's characteristics, a problem, which works can be used without any restriction, should be solved. Thus, past copyright law may be amended based upon multimedia environment. The problem which should be solved is also discussed.

The purpose of this study was to examine if mothers and their children used different interaction strategies depending on the interacting contexts. Sixty-five mothers and their children were observed while they interacted with each other in two contexts, that is, a free play context and a joint problem solving context. The result of this study showed that first, the mothers' strategies and their children's strategies were closely related. When the mothers used positive strategies, their children also responded with positive strategies. In contrast, when the mothers used negative strategies, their children also tended to use negative strategies. Second, the contexts which the mothers and their children interacted affected the strategies that the mothers and their children used. The mothers and the children were more likely to use positive strategies in the context of free play than in the context of the joint problem solving. This result points out the importance of free play as the context of producing a positive atmosphere where the mothers and their children interacted positively and had a good time. Suggestions for further study and implications for parents were provided.

지난 4월 1일 제주도 한라산 정상에 135명의 한국물류정보통신 임직원은 결연한 마음으로 한자리에 모여, '주식회사 케이엘넷'이라는 새로운 사명과 함께 글로벌 물류 IT전문 기업으로 도약하고자 하는 사명선포식을 가졌다. 주식회사 케이엘넷(KL-Net)의 사명 변경은 지난해 임직원이 심기일전 하여 수립한 '비젼 2020 - 세계적인 물류 IT 전문기업'으로의 도약을 위한 서막에 불과하다. 지난 2004년 3월, 주식회사 케이엘넷은 "채무부정보증"이라는 뼈아픈 금융사고가 있었다. 이로 인해 임직원간의 불신은 극에 달했고, 그 당시 100억원이라는 손실액은 기업 존폐의 기로에까지 놓이게 되었다. 케이엘넷의 대표이사로 부임한 박정천 대표사에게는 금융사고 관련 소송뿐만 아니라 기업 정상화라는 두 가지의 막중한 과제를 해결해야 하는 큰 역할이 주어 졌다. 박 사장은 먼저 금융사고로 야기된 임직원간의 불신을 해소하는데 노력했다. 임직원의 생일이나 결혼기념일 등을 본인이 직접 축하 메세지를 보내는 것부터 시작하여, 임직원간 친밀감을 갖도록 노력하고 서로 신뢰하고 믿고 따를 수 있도로 하는 한편, 직원들에게 정직을 더욱 강조하였다. 지난 3월 정기 주주총회에서 케이엘넷 주주들은 어려운 과제를 깔끔하게 해결한 박 대표를 연임시켰다. 박 대표의 지난 2년간의 공로와 앞으로 케이엘넷을 '세계적인 물류 IT전문기업'으로 성장시킬 수 있다는 리더쉽을 높이 평가한 것이다. 당장의 사업성과보다는 회사의 경쟁력과 성장기반을 다지는 것을 최우선 과제로 지난해 임직원과 함께 수립한 '비젼 2020'을 향하여 전력 질주하고 있는 주식회사 케이엘넷 박정천 대표이사를 만나본다.

The Korean government proposed the K-SDGs in 2019 to promote the UN SDGs, but the role and tasks of science and technology, an important means of implementing the SDGs, have not been materialized. Accordingly, the role of science and technology ODA for the SDGs was established through the Ministry of Science and ICT's policy research project 'Science and Technology ODA Promotion Roadmap for Spreading the New Southern Policy and Realizing the 2030 SDGs'. In addition, goals, strategies, and core tasks for the next 10 years were derived in 10 fields such as water, climate change, energy, and ICT. In this paper, we analyze 30 key tasks of the ODA promotion roadmap for science and technology for the realization of SDGs, and propose mid- and short-term tasks and implementation plans for effective roadmap promotion. Among the key tasks in each field, four common elements were derived: ICT/smartization, a global problem-solving center, cooperation/communication platform, and business model/startup support platform/living lab that can create and integrate roadmap implementation conditions. In addition, the four mid- and short-term tasks, 1) Establishment of science and technology ODA network, 2) Establishment of living lab business platform linked to start-up support business, 3) Local smartization of recipient countries, and 4) Expand and secure sustainability of global problem-solving centers, were set in relation to the implementation of the detailed roadmap. For the derived mid- and short-term tasks, detailed implementation plans based on the ICTization of global problem-solving centers were presented. The implementation of the mid- and short-term tasks presented in this paper can contribute to the more effective achievement of the science and technology ODA roadmap, and it is expected that Korea's implementation of SDGs will also achieve high performance.
