We present a reinforcement learning-based framework for generating 2D Lego puzzle from input pixel art images. We devise heuristics for a proper Lego puzzle as stability and efficiency. We also design a DQN structure and train it to maximize the heuristics of 2D Lego puzzle. In legorization stage, we complete the layout of Lego puzzle by adding a Lego brick to the input image using the trained DQN. During this process, we devise a region of interest to reduce the computational loads of the legorization. Using this approach, our framework can present a very high resolutional Lego puzzle.

The purpose of this study is to critically review recent discourse on aging appeared in Korean newspapers. For this purpose, 1,725 articles on 'aging' or 'elderly' appeared on three major Korean newspapers during 1997- 2006 are analyzed. It is shown that there is a recent surge of articles portraying the positive images of aging in Korean newspapers emphasizing the importance of productive, successful aging and active life style of the elderly. This trend is a welcomed change from the negative images of elderly as dependent burden of society. However, it seems that over emphasis on positive aging and 'New Elderly' might have created another stereotype about the elderly and unintentionally marginalize the certain group of the elderly. By focusing on individual responsibility, it also overlooked the constraints imposed by social structure on disadvantaged elderly group, such as women, elderly in low socio-economic strata. Theoretical and policy implications of this trends are discussed.

This study deals with the "Dissemination Stage", the final step in the R&D process consisting of R&DDD($R&D^3$ : Research & Development, Demonstration, Dissemination). At the "Dissemination Stage", the newly configured technical design is compared with other alternatives to come up with the most desirable selection. The assessment conducted at this stage is not a simple procedure. It goes through the complex evaluation process in which various elements including economic effects and technical characteristics are considered. The reason for taking such a complex procedure is that the assessment, selection and application of the desirable technical alternative is critical for the company's competitive edge in every field of industrial sectors, thus influencing its survival and continuous growth. This study reviews the AHP method for assessing technical alternatives of the heat supply system design. And, to show the practical validity of the AHP method, it is applied to the evaluation of waste heat system alternatives in the field of energy supply system technology.

I intend to grope for the desirable outdoor color environment creation plan through researching situation of our apartment houses color environment and grasping the point at issue. The rearch was made that Ilsan(16 items) new city apartment were selected and the color seperately measured such as the dominant, the aid, the accent colors through applied color component ratio was researched by calculating square measure of matched colors and through that the evaluation of apartment complex color environment was formed. The planned construction problems were issued from comparing the planned scheme and the present carrying color status guide by investigating the color plan applied Ilsan new city. The current out apartment outdoor color environment is poor, and the color plan of the early stage has many insufficient parts and many operation errors. For the creation of desirable color environment, the color plan establishment by regional characteristics, the color environment management, though exhaustive color consultation, and the external construction technique improvement, the standard color sheet diffusion, the color understanding of architects, the public relations (P.R), the education on the importance of color are required.

In this research, we designed an educational activities of exploring mathematics programs in a course of mathematics education in teacher's college. We divided future mathematics teachers into 8 groups and suggested 8 mathematics programs to them. Each group explored one mathematics program. We asked to future mathematics teachers exploring some cases that use effectively a mathematics program in the teaching of school mathematics. In the process of an exploring, we designed some activities of teaching and learning. We provided opportunities of long-term exploration, group learning, presentations, exercises, reflections to mathematics teachers. As a result, future mathematics teachers acquired basic knowledge on the usage of mathematics programs in school mathematics textbook. In addition, their capabilities that are needed to explore mathematics programs have been enhanced. Also they had learned the teacher's positive attitude through the activities of teaching and learning.

The purpose of this study was to find out the characteristics of learning contents structure of K-12 science textbooks. The characteristics are related to 7 main concepts of matter properties; reaction rate, other reaction, density, solution, state change, absorption, and surface property. The contects are analyzed into 5 types of characteristics; type of concept extension, type of concept deepness, type of same level concept, type of confusion with other concepts, and type of concept interruption. First two types are positive content structures, but the others are negative structures. The findings are as follows. First, a lot of learning contents have the characteristic of 'type of same level concept'. There are few which have the characteristic of 'type of concept deepness'. Second, there are a lot of concepts related to 'properties of matter' which are not represented any more in middle and high school science textbooks. Those concepts are importantly taught in early childhood education and elementary school science. Most of the learning contents don't represent 'type of concept deepness'. Therefore the science textbooks needs to be restructuring.
