  • This study aims to find new solutions to the problem of utilization of materials and techniques represented in the development of modern lighting design. LED is an important component in modern lighting design and pine tree is one of the most popular domestic wood in furniture design in Korea. In this study, design is developed into various types of furniture such as a table, a chest, and a lighting, by researching manufacturing process and examining the use of slicing pine tree. The technique of slicing pine tree is a simple linear arrangement that was traditionally used in wooden furniture in Lee dynasty, with an emphasis on repetitive rhythm. The slicing technology is used to expand the usage of domestic pine tree. The beauty of natural wood is expressed with the transmission of light by applying this technique to the lighting design. It also brings new communication in between artificial lighting and natural wood combining this traditional technique and LED lighting in design. Finally, this study suggests particular value through the convergence of analog and digital by using the traditional wooden technique that keeps natural wood prints and new digital technology by using LED lighting. More discussions and research about this subject are expected continuously through this study.

  • To date, facility layout problems has been solved and applied for job shop situations. Since flow shop has more restrictions, the solution space is much smaller than job shop. An efficient heuristic algorithm for facility layout problems for flow shop layouts is needed to be developed. In this thesis, a heuristic algorithm for rectangular bay layouts in a flow shop situation is presented. The proposed algorithm is developed by using slicing tree representation and applied to various flow shop layout problems. The effectiveness of the proposed algorithm in terms of exploration rate and objective function value are shown by comparing our results to simulated annealing.

  • In the previous work, we presented HDTS for locating logical errors in Java programs. The HDTS locates an erroneous method at an execution tree using an algorithmic program debugging technique and locates a statement with errors in the erroneous method using a step-wise program debugging. The technique can remove the unnecessary statements and nodes in debugging using a program slicing technique at the execution tree. So HDTS reduces the number of program debugging. In this paper, we design HDTS system for debugging java programs. We define small subset of Java language and design the translator that translates java source codes and the virtual machine that runs java programs. We design GUI(Graphical User Interface) for debugging.

  • In the previous work, we presented HDT for locating logical errors in Java programs. The HDT locates an erroneous method at an execution tree using an algorithmic program debugging technique and locates a statement with errors in the erroneous method using a step-wise program debugging. It reduced the number of programmer debugging in Java programs. But the HDT still increases the number of debugging because the size of the recent programs increases than the past programs and the number of methods is increasing. This paper proposes HDTS using a program slicing technique (PST) at the MDT. HDTS can reduce the number of programmer debugging. Specially, the more the number of methods and statements increases, the more HDTS has effects.

  • This paper presents a system for facility layout problem using an expert system and a genetic algorithm. The practical facility layout design can be effected by characteristics of constructing model, slicing tree model, closeness weight metric and expert system. The genetic algorithm searches the result layout. An experimental system is implemented and produced desired layout.
