Cognitive subject imposes structures on an object to shape it into a structured thing. Structures that the subject imposes on an object in a given problem context can be diverse horizontally and vertically. In view of the horizontal diversity of structure, problem-solving activities focusing on various structures may enrich the present problem-solving education which emphasizes applying and comparing a couple of problem-solving strategies. Finding an algebraic formula for a figural pattern should be regarded as a new starting point of searching for more various structures. In view of the vertical diversity of structure, it should be aware that students may see different structures from the structure that their teacher expect them to see. The vertical diversity of structure enables us to provide students with experience of progress.

The purpose of this study was to analyze mathematical errors and the effects of reflective problem posing activities on students' mathematical problem solving abilities and attitudes toward mathematics. We chose two 5th grade groups (experimental and control groups) to conduct this research. From the results of this study, we obtained the following conclusions. First, reflective problem posing activities are effective in improving students' problem solving abilities. Students could use extended capability of selecting a condition to address the problem to others in the activities. Second, reflective problem posing activities can improve students' mathematical willpower and promotes reflective thinking. Reflective problem posing activities were conducted before and after the six areas of mathematics. Also, we examined students' mathematical attitudes of both the experimental group and the control group about self-confidence, flexibility, willpower, curiosity, mathematical reflection, and mathematical value. In the reflective problem posing group, students showed self check on their problems solving activities and participated in mathematical discussions to communicate with others while participating mathematical problem posing activities. We suggested that reflective problem posing activities should be included in the development of mathematics curriculum and textbooks.

In this article, we examine the current status and problems of research and development of social problem solving in university. Social problem solving R&D is characterized by pursuing social goals and participatory research and development. This paper summarizes the problems faced by the social problem solving R & D in the university and the remedies based on the focus group interview. 1) Establishment of 'the Social problem-solving R&D center' to create a base for embedding social problem-solving R&D within the university; 2) To develop and disseminate social problem solving research and development models suitable for universities; 3) Activation plans for vitalizing the participation of mainstream researchers and civil society in the social problem solving R&D were discussed.

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 wide diffusion of internet and the overall increased reliance on technology for information communication, dissemination and gathering have created an unparalleled mass of data. Sifting through this data is defining and will define in the foreseeable future a big part of contemporary computer science. Within this data, a growing proportion is given by personal information, which represents a unique opportunity to study human activities extensively and live. One important recurring challenge in many disciplines is the problem of people re-identification. In its broadest definition, re-identification is the problem of newly recognizing previously identified people, such as following an unknown person while he walks through many different surveillance cameras in different locations. Our goals is to review how several diverse disciplines define and meet this challenge, from person re-identification in video-surveillance to authorship attribution in text samples to distinguishing users based on their preferences of pictures. We further envision a situation where multidisciplinary solutions might be beneficial.

This study examines the effects of learner's metacognition and scaffolding types on problem solving processes by examined 49 undergraduates to identify effective scaffolding type in Web-based PBL. This study classifies problem solving processes as defining the problem, developing solutions, making selections and justifications for the Proposed solution(s), and monitoring the solution. Moreover, it classifies scaffolding types as subject-related scaffolding and process-related scaffolding. As a result, the upper metacognition group showed higher performance only in monitoring solutions than the lower metacognioon group. This study also showed that offered scaffolding effects are not statistically significant. However, the lower metacognition group showed higher performance when subject-related scaffolding was offered and the upper metacognition group showed higher performance when process-related scaffolding was offered in making selections and justifications for the proposed solution(s) and monitoring solution. This study, based on the result of research, can partially verify the effects of learner's metacognition on problem solving processes and interaction effects between scaffolding and metacogniton in Web-based PBL.

지식공학을 이용한 전문가시스템이 날로 고도화 되어가는 전력계통운용 기술에 대한 컴퓨터 적용상의 불충분한 과제를 해결하기 위하여 여러 분야를 대상으로 많은 연구가 진행되고 있으며 또한 일부 실용화 되고 있다. 그러나, 실용하되고 있는 분야에서도 지식베이스를 어떻게 확대해 나가느냐가 중요하며, 교과서적인 기본이론에 대한 지식은 충분히 갖추고 있으나 경험적 지식은 미흡하여 이것을 증대시키는 것이 과제가 되고 있다. 또한 전력계통운용분야에서 계통사고판정과 복구지원 업무에 대한 전문가 시스템이 가장 앞서서 개발되고 실용화가 확대되고 있으나, 계통의 정확한 사고판정을 위해서는 보호계전기 동작정보가 필수적으로 요구되는데, 현재의 중앙급전용 EMS에서는 정보의 취득주기와 시간동기, 그리고 정보량등의 문제로 이들 보호계전기 동작정보를 취득해오지 못하고 있으며, 이들 문제들이 선행되어 해결되어야만 온라인 제어시스템과 유기적인 협조하에 전문가시스템의 실용화가 정착되리라 본다.
