Problem Solving has been emphasized for recent decades, and many research case studies have been used to improve students' Problem Solving abilities. However, the gap of students' abilities can be easily shown after enrollment into school in spite of scholar's attempt to reduce students' level of differentiation. Besides, it is clear that teachers have been too readily assisting students' and not allowing them to acquire the process of Problem Solving, and this may be due to impatience. Therefore, students seem to show signs of the dependent tendency towards teachers and other materials. This tendency easily allows students' to depend on teaching resources without attempting any developmental mechanism of Problem Solving. The presupposition of this study is that every student must solve a problem without any assistance, and also this study is to provide new cognitive strategies for both teachers and students who want to solve their problems by themselves through the process of visible Problem Solving. After applying the student-based problem-solving model by this study, it was found to be effective. Therefore this will lead to the improvement of the Problem Solving and knowledge acquisition of students.

In this study, we consider to assess the information ability of individuals related to local information. Questionnaire surveys are frequently used for studies on the measuring of information index and such specified indexes of society development. However, if questionnaire papers measured individuals' abilities and such parts of quality, the subjective judgments of respondents cannot but be intervened. Therefore a method which will enable subjective points to be comparatively objectified is needed. In this study, when an attempt is being made to measure individuals' information capacity through questionnaire surveys as the process for calculating the standards of regional information levels. Cases have been looked at for times when, by using a scorecard, individuals' subjective survey result have been be changed to be comparatively objectified scores and such process. The logit model was used in the preparation of the scorecard. In this study, we have presented a clue which enables the comparative measurement about regional information gaps by using characteristics of regional population statistics.

LIDAR data, as the source of the 3D information of buildings, are used many modeling fields such as three-dimensional city models in urban planning and the visibility analysis of buildings. This study suggests a methodology, that is characterized by combining image-based and point-based process, for minimizing the user's intervention and automatically extracting building boundary only using the LIDAR data. Image processing methodology is firstly used to separate building and non-building regions from LIDAR data. Moreover, building regions are then classified main roof into remaining parts by the statistical analysis of height values, and the remaining parts are processed separately. Through the experimental results of study areas which exist many types of buildings, for example, apartment-type, stair-type, complex-type, etc. Approximately 90% building boundaries are automatically extracted by the proposed methodology.

The purpose of this study is to see the effects of school climate on school violence and fears of attending school. The direct relationship between school climates and fears of attending school will be examined, as well as the indirect and mediated effects of school violence in that school climates influence the fears of attending school. A theoretical model of the relationships of school climates, school violence, and fears of attending school will be given. The subjects of the surveys were chosen from 12 junior high schools in the Seoul, Gyeonggi area through convenience sampling. 1,317 surveys were then analyzed. School climates directly affect the fear of going to school through the mediums of peer and teacher violence. The derived results stress the necessity of improving school climates in order to reduce violence from peers and teachers and to reduce fear of attending school.

This research empirically explores the relationship between types of performance information use, decision making behaviors and performance of government organizations. We measured two types of using performance information, relevance of performance index, variety of performance information, and levels of manager intervention by surveying performance managers of each government ministry or agency and also measured performance by using performance reports. The results of fuzzy-set qualitative comparative analysis suggest that hard use and soft use have impact on performance by combining with characteristics of performance information and managers decision-making by intervening performance management processes.

The purpose of this study is to obtain basic data to be used in social welfare intervention for relieving psychological burdens caused by job stress in the eco-boomer generation that will be the center of Korean society in future, by estimating job stress change trajectories of the eco-boomer generation in the convergence era, figuring out predicting factors and examining job stress factors that individuals experience, in accordance with the degree of job stress and the changes. This is a longitudinal study using secondary data and for analysis, the Latent Growth Model(LGM) was applied to the 1st year to the 7th year Korean Welfare Panel Data. Self-esteem was one of job stress predicting factors of the eco-boomer generation. Since most of eco-boomers were students in the early measurement period, the level of job stress was low, but over time, the burden of job increased by gradation. This study has significance by providing an empirical basis for predicting factors of job stress changes of the eco-boomer generation to understand job stress in the eco-boomer generation.
