Planning occurs from day-to-day, small-scale decisions to large-scale infrastructure investment decisions. For that reason, various attempts have been made to appropriately assist decision-making process and its optimization. Lately, initiation of a large amount of data, also known as big data has received great attention from diverse disciplines because of versatility and adoptability in its use and possibility to generate new information. Accordingly, implementation of big data and other information management systems, such as geographic information systems (GIS) and building information modeling (BIM) have received enough attention to establish each of its own profession and other associated activities. In this extent, this study illustrates a series of big data implementation cases that can provide a lesson to urban planning domain. In specific, case studies analyze how data was used to extract the most optimized solution and what aspects could be helpful in relation to planning decisions. Also, important notions about GIS and its application in various urban cases are examined.

This study examines how open-ended tasks can be implemented with the support of redefined learning goals and teaching practices from a student-centered perspective. In order to apply open-ended tasks, learning goals should be adopted by individual student's cognitive levels in the classroom context rather than by designated goals from curriculum. Equitable opportunities to share children's mathematical ideas are also attainable through flexible management of lesson-time. Eventually, students can foster their meta-cognition in the process of abstraction of what they've learned through discussions facilitated by teachers. A pedagogical implication for professional development is that teachers need to improve additional teaching practices such as how to tailor tasks relevant to their classroom context and how to set norms for students to appreciate peer's mathematical ideas in the discussions.

The purpose of the paper is empirically to explore 'design manner', focusing on the designer's knowledge boundary on the designer-user interactions in the design process. This study conducts a field study and observed designer's interactions with actual users in a leading user-centered design firm over three months. The observations revealed how designers bring ideas about users into design without physically interacting with users during the design process. Based on Bourdieu's theory of practice and the concept of boundary objects, this study introduces the concept of 'design manner', by which designers incorporate user's ideas into the design process without actual involvement of users in the process. This paper contributes to the body of knowledge by introducing the design manner in-between designer's and user's knowledge boundaries and argue bridge between theoretical and actual designer-user interactions in the IS design process.

Background: In this study, we aimed to investigate the recent trends for health care indicators including maternal mortality ratio, infant mortality rate, under-five mortality rate, life expectancy, years of life lost, and healthcare resources in South Korea, North Korea, Germany, Russian Federation, Mongolia, Vietnam, China, Czech Republic, Poland, and Hungary. Methods: We used data from five sources: World Health Organization, Federal Institute for Population Research, World Bank, Organization for Economic Cooperation and Development health statistics, and national statistics. Results: In the early 1990s, health indicators continued to improve in countries that switched to the health insurance system, but the gap widened in North Korea as health indicators worsened. Conclusion: The establishment of a sustainable health care system after unification of the Korean peninsula requires substantial changes in the health care system and efforts to improve the health of North Koreans.

The purpose of this paper is to develop a new group classification method based on genetic algorithm and to com-pare its prediction performance with those of existing methods in the area of bond rating. To serve this purpose, we conduct various experiments with pilot and general models. Specifically, we first conduct experiments employing two pilot models : the one searching for the cluster center of each group and the other one searching for both the cluster center and the attribute weights in order to maximize classification accuracy. The results from the pilot experiments show that the performance of the latter in terms of classification accuracy ratio is higher than that of the former which provides the rationale of searching for both the cluster center of each group and the attribute weights to improve classification accuracy. With this lesson in mind, we design two generalized models employing genetic algorithm : the one is to maximize the classification accuracy and the other one is to minimize the total misclassification cost. We compare the performance of these two models with those of existing statistical and artificial intelligent models such as MDA, ANN, and Decision Tree, and conclude that the genetic algorithm-based group classification method that we propose in this paper significantly outperforms the other methods in respect of classification accuracy ratio as well as misclassification cost.

Information and Communication Technology is now widely accepted by developing countries as a development tool in their efforts to alleviate poverty, enhance human development, and achieve Millennium Development Goals. Recognizing this untapped potential and development strategies incorporating ICT are being increasingly promoted and launched across the developing countries requiring a comprehensive ICT policy that plays a crucial rule, in particular, in the area of agriculture and rural development. While the potential advantages of ICT for development are enormous in developed countries, national policies of developing countries are yet to adequately reflect truly comprehensive and integrated strategies for harnessing and exploiting this potential. This paper tries to provide implication of ICT policy to the agriculture and rural development in developing countries, in particular through lessons learned from European Union (EU) IT policy. Through the examination of vital projects in the agriculture and rural development sectors and case study analysis of applied policies and strategies implemented in the European Union, this paper provides tangible examples and lessons for policy-makers and practitioners involved in the field. Hence, this study provides policy-makers the necessary tools, information and knowledge to facilitate the formulation and adoption of ICT policies and strategies in the agriculture and rural development sector.

In Korea, primary school (also junior high school) is compulsory and free since 2004. But it looks high school is also compulsory, as over 80% of adults has a high school diploma currently. For 20 years improving high school education is only education-oriented, rather than occupation-oriented. And, the mismatch between the occupational requirement and the lesson from school is getting larger. To resolve this issue, the Korean government builds and utilizes National Competency Standards(NCS) to realize a competence-oriented society. With NCS, the government enables to run of a work-study program and tries to suggest the fundamental solution to improve occupational ability and the unemployment of young people. However, the prejudice against the education level and occupation is still engrained, and it is hard to match the education-career-qualification based on NCS. Therefore, we study NCS from the definition to the utilization, suggest an improving method to flexibly utilized the standards in the fields, and continuously improve and develop the NCS.
