Automation of wood processing is strongly required to improve the productivity and quality of wood products in wood industry which is one of the most labor-intensive industries. Classification of surface defects on wood boards such as knots is one of the important steps towards a completely automated wood processing system. In this study the possibility of detection of knots by image processing technique was investigated. Algorithm for the automatic determination of threshold value was developed to enhance the flexibility of image processing system. Two different approaches, grid method and tile method, were developed to enhance the speed in extracting features from images. Grid method showed slightly higher processing speed and tile method proved much more stable in determining threshold values. Tile size of $5{\times}5$ pixels or $6{\times}6$ pixels was found to be proper to get stable results with resonable processing time.

Because PBD was started as a design tool for steel construction and concrete construction, it was able to applied to the post and beam method of wooden building constructions. But, it may not suitable to light frame wooden construction that is becoming popular in domestic construction market due to the economical efficiency and the constructive simplification. Owing to the share effects between member and sheathing material or among structural members, light frame wooden construction is different from post and beam construction that use a single structural member. Therefore, consideration on the system analysis and system design are urgently needed to use in actual life and inspect the reliability of structures from the system view. With this in mind, code conversion from ASD to PBD that is pressing issue in domestic wooden building construction was studied, also various countries status about PBD were considered and then approaching methods on the system reliability were referred. Finally, several considerations for the development of PBD were explored. PBD should be considered as, not only a new structural design process that select sizes of structural member, but a industrial tool that can lead a development of more reliable wood products. A strongest point of PBD is independent of various construction materials and construction types.

The purpose of this study is to examine how the floor heating system is affecting to users in childeren's libraries. This study included the method that extracts the affordance of the floor heating system, after surveyed using behavior in children's libraries and referred to J. J. Gibson's affordance and surface concepts. As the positive affordance, it was grasped that the floor heating system promotes social relationships and affords various surfaces for library using, but also as the negative affordance, that hinders users in the public usings and the behaviors for reference and using. The behaviors of these various characters can be regarded as life behaviors resulted from the sitting life style and the natural using behavior can give to children emotional rest and autonomous reading experience. For the function as the children's library, the learning of sociality in the public building and the various reading space, the space planning of children's library should be done after the positive and negative affordances extracted from this study are reflected. The guidelines for space planning are summarized as the followings: the layout of book furniture, the shoe chest and the space around that, the furniture hight and children's eye level, and the practical using of the table for sitting life style.

다변화된 세계정세와 글로벌 경쟁시대에서 <産>과 <學> 모두는 새로운 패러다임을 인식하고 이에 대처해야 할 입장에 있다. 특히 가구분야에 있어서 기업은 전략적 차원에서 디자인을 적극 수용하여 경쟁력을 강화해야할 것이며, 대학을 중심으로 한 교육기관에서는 우수한 디자이너들을 배출하여 가구산업발전에 이바지해야 할 것이다. 이를 위해서는 <産>과<學>이 서로의 인적.물적자원을 교류하고 지원협조하는 <산학협동>의 활성화가 절대 필요하다. 생산이 안된 디자인이나 디자인 없는 생산제품이란 존재할 수 없다는 관점에서 볼 때 더욱 절실한 문제이다. 교육은 대학이, 생산은 기업이 맡는다는 편협한 사고에서 벗어나 유기적인 협조체제를 구축하여 새로운 시대를 맞이하고자 하는 공동인식이 요구된다.

Since luxurious apartments have appeared in Korean common housing, there have been a series of stages in reflecting the demands of residents. However, lifestyles have been restricted to a typified pattern because housing was provided extensively during a short period. The ensuring of residency in common housing lies in seeking how to utilize a given space to the maximum. In the presence of residents, the characteristic of today's housing is not merely satisfied with residents, but provokes the function of a new supplier. Residents are changing by situation (economic, social, cultural, and family types), yet housing is falling short of the change. In particular, it is necessary to closely observe the change in housing by time and space in accordance with both psychological and physical changes of family members. Therefore, this study aims to furnish an opportunity to prepare the foundation of alternatives, which may cope with the future in housing design and furniture design through the latest cases at home and abroad as well as a theoretical background of issues concerning a variable system, which will suit the demands of residents.

This study aims to organize the research ways of interior design for clothing stores as a management strategy in the market changing rapidly. The public met their needs in a mass production system. However, the brand-name companies began to create the conditions of consumption for people, there appeared people with new lifestyles and new way of thoughts so that their propensity to consume resulted in consumption activities, and it become varied, individual, and highly qualified. Therefore, in view of consumers' priority, based on SI sales environment this paper aims to create a new image by re-designing the interior and furniture of shops which will help to enhance the image of brand name. Therefore, the brand-name companies will expect a large sale for the new product and it will apply to sales environments of other products and influence them. The purpose of this paper is to find a desirable way to increase sales efficiency for the companies. In order to get a concept and propriety of sales environment design, examined mutual relation to each study of interior design, marketing, and fashion design. Through referring to the documents research of these fields I could get a conception and basic structure for them. Based on the theoretical knowledge, this study was made to show to examine and generalize the existing sales environments and situations and set up a new concept for this. It will apply to interior design and store holds and present a new design alternative for improvement.

In the present work, we isolated and identified Aspergillus sydowii NYKA 510 as the most potent laccase producer. Its medium constituents were optimized to produce the highest possible amount of laccase, which was after 7 days at 31℃ and pH 5.2. Banana peel and peptone excelled in inducing laccase production at concentrations of 15.1 and 2.60 g/l, respectively. Addition of copper sulfate elevated enzyme yield to 145%. The fungus was employed in a microbial fuel cell (MFC). The best performance was obtained at 2000 Ω achieving 0.76 V, 380 mAm^-2, 160 mWm^-2, and 0.4 W. A project to design a self-sufficient lighting unit was implemented by employing a system of 2 sets of 4 MFCs each, connected in series, for electricity generation. A scanning electron microscopy image of A. sydowii NYKA 510 was utilized in algorithmic form generation equations for the design. The mixed patterning and patterned customized mass approach were developed by the authors and chosen for application in the design.
