In recent years, there has been a gradual increase in the number of R&D projects for solving societal problems. However, government-funded research institutes(GRIs) are going through many trials and errors due to the lack of R&D systems suitable for solving societal problems. In this regard, this study attempted to discuss the improvement directions for evaluation systems of GRIs, which serves as a major influencing factor in performing R&D initiatives for solving societal problems. Towards this end, a study of R&D initiatives for solving societal problems was conducted first, and improvement directions for effective promotion were presented after deriving limits in terms of R&D initiatives for solving societal problems, along with the current status of evaluation systems by GRIs. Lastly, implications and limitations of this study were discussed. This study has its significance in that it is the first research to propose evaluation indicators in terms of solving societal problems at the level of GRIs and is expected to be a foundation for future research of related fields.

This study was to identify the relationship among self-resilience, emotion expressiveness, achievement motivation, and problem-solving ability of nursing students and provide data to increase problem-solving ability for nursing students based on the results. This research involved 229 nursing students in B city. The analyzed by the t-test, ANOVA, Pearson's correlation coefficient using SPSS/WIN 22.0. In results of the study, there were significant differences in problem-solving ability with respect to grade (F=4.021, p=.008), academic level (F=3.791, p=.024), satisfaction of major(F=11.140, p<.001), Accomplishment (F=8.000, p<.001), interpersonal relationship(F=16.944, p<.001). There were positive correlation between problem-solving ability and self-resilience(r=-.532, p<.001), between problem-solving ability and emotion expressiveness(r=.365, p<.001), between problem-solving ability and achievement motivation (r=.694, p<.001). Through this research requires the fellow study to determine the factors affecting problem-solving ability of nursing students.

This study deals with the process by which 'Social problem-solving R&D model' is established in Korean society through the evolution of the government's R&D program. We will examine the process by which a 'Social problem-solving R&D model', which was not present in companies, science and technology communities, and civil society, is formed through government R&D programs. To this end, we present a conceptual framework to analyze the process of co-evolution of 'Social problem solving R&D model', the organizational community that supports and implements it, and the institutions that supports the new model. In the synthesis, policy measures to enhance 'Social problem-solving R&D model' are dealt with.

Research question and method play important roles in conducting a research in a scientifically valid way. In today's digitalized research environment, social network service (SNS) has rapidly become a new source of big data. While this shift provides new challenges for researchers in Korea, there is little scholarly discussion of how research questions can be framed and what statistical methods can be applied. This article suggests some basic but primary types of example questions for researchers employing social big data analytics. Further, we illustrate the interface of the intended data set specifically for SNS-mediated communication and information exchange behaviors. Lastly, a statistical test known as proper method for social big data is introduced.

오늘날 제 7차 교육과정은 학습자의 사고과정과 능력을 다양한 평가방식으로 실시하도록 권유하고 있다. 이러한 목적을 구현하기 위하여 수학과 평가는 교수-학습에 유용한 평가, 과정 중심의 평가, 다양한 방법을 활용하는 평가가 되어야 할 것이다. 이는 학습자로 하여금 스스로 학습하도록 가정하는 인식론적 변화에 바탕을 둔 최근의 평가 동향과 맥을 같이 하고 있다. 평가에서 학생의 수학활동 역시 특히 인지적 영역의 다양성을 지닌 개인에 의하여 이루어지기 때문에 수학 평가는 단편적인 정형화된 지식이 아닌 문제 해결의 전략이나 발견술과 같은 요소에서 강조되고 있는 비정형의 문제들을 통한 메타인지적인 발달과정을 고려해야 한다. 본 연구에서는 학생이 준개방형 평가문제를 해결하는 과정을 통해 자신이 얼마나 알고 있는가를 인식하며 자신의 문제 해결 전략을 점검하고 평가하는 인지적 능력에서 일어나는 변화를 알아보는 데 그 목적이 있다. 지금 현재 연구가 진행 중이며 본 연구의 결과는 다음 논문집에 발표할 예정이다.

e-Science는 차세대 가상 협업 연구 패러다임으로, 필요한 연구 자원들을 융합하여 연구자들에게 제공함으로써 언제 어디서든지 자유롭게 협동 연구를 할 수 있도록 하는 환경 또는 연구 활동 그 자체를 의미한다. 이러한 e-Science의 필수 요소들 중 하나로 문제 해결 환경을 들 수 있는데, 문제 해결 환경이란 어떤 특정 영역의 문제를 풀기위해 필요한 모든 계산 자원을 제공하는 하나의 컴퓨터 시스템을 말한다. 본 논문에서는 e-Science 환경을 위한 웹 기반의 병렬 문제 해결 환경을 제안한다. 이 시스템은 전자기파 관련 분야의 전산모사를 병렬로 수행하며, 웹 기반의 인터페이스를 제공한다.

창의성과 지능, 뇌 기능 분화의 관계와 수학 창의성과 지능과의 관계에 대해서는 많은 연구가 이루어지고 있으나 뇌 기능 분화와 수학 창의성, 수학 창의적 문제 해결력과의 관계를 규명은 미흡한 상태이고, Balka(1974)의 연구에서는 수학 창의성과 일반 창의성은 관계가 없다는 연구결과가 있다. 이러한 사실을 바탕으로 생각할 때 뇌 기능 분화와 창의성간의 상관관계의 연구에서 얻어진 결과가 수학 창의성과 관계가 있는지 살펴볼 필요가 있다. 본 연구에서 남녀에 따른 뇌기능 분화의 차이와 좌뇌, 우뇌와 전뇌의 수행 수준이 수학 창의적 문제해결력과는 어떠한 관계가 있는지 알아보기 위해 대구광역시 내에 있는 초등학교 5학년의 40명을 대상으로 뇌 기능 분화 검사, 창의성 검사를 실시하여 서로의 관계를 분석했다. 연구 결과 뇌의 기능 분화 발달은 좌뇌는 남자가 우뇌는 여자가 높았으나 통계적으로 의미가 없었고, 전뇌 집단이 수학 창의적 문제해결력이 가장 높았으므로 전뇌를 고루 발달시킬 수 있는 교수전략에 관한 연구들이 계속 되어져야 할 것이다.

As the expansion of road capacity has become impractical in many urban areas, congestion pricing has been widely considered as an effective method to reduce urban traffic congestion in recent years. The principal reason is that the congestion pricing may lead the user equilibrium (UE) flow pattern to system optimum (SO) pattern in road network. In the context of network equilibrium, the link tolls according to the marginal cost pricing principle can user an UE flow to a SO pattern. Thus, the pricing method offers an efficient tool for moving toward system optimal traffic conditions on the network. This paper proposes a continuous network design program (CNDP) in network equilibrium condition, in order to find optimal congestion toll for maximizing net economic benefit (NEB). The model could be formulated as a bi-level program with continuous variable(congestion toll) such that the upper level problem is for maximizing the NEB in elastic demand, while the lower level is for describing route choice of road users. The bi-level CNDP is intrinsically nonlinear, non-convex, and hence it might be difficult to solve. So, we suggest a heuristic solution algorithm, which adopt derivative information of link flow with respect to design parameter, or congestion toll. Two example networks are used for test of the model proposed in the paper.

본 논문에서는 1차원 스트링과 2차원 텍스트를 유동적으로 정렬하는 소위 1-2차 연성 정렬 문제를 정의하고, 이 문제를 위한 동적 알고리즘을 제시하고, 응용 예를 보인다. 문제의 패턴은 그 길이가 주어져 있지만 그 형체가 유연성을 갖고 있어 변형될 수 있다는 점이 지금까지 연구되어온 패턴 매칭 문제와 다르다.

This study investigated three pre-service teachers' mathematical problem solving among hand-in-write-ups and final projects for each subject. All participants' activities and computer explorations were observed and video taped. If it was possible, an open-ended individual interview was performed before, during, and after each exploration. The method of data collection was observation, interviewing, field notes, students' written assignments, computer works, and audio and videotapes of pre- service teachers' mathematical problem solving activities. At the beginning of the mathematical problem solving activities, all participants did not have strong procedural and conceptual knowledge of the graph, making a model by using data, and general concept of a sine function, but they built strong procedural and conceptual knowledge and connected them appropriately through mathematical problem solving activities by using the computer technology.
