The placeness has been lost in space design since Modernism, especially Internationalism. Digital space design of today is one of the means to complement that. The purpose of this study is to grasp a trend in the expression of placeness, being appeared in digital space design process through case analysis. As the result of this study, the placeness in digital design process expressed by parametric elements had each effective internal algorithms. Especially, space design using digital process were expressed placeness by physical context such as topography, conditions of location, landscape, axis of road, traffic elements and climate. And social context were expressed by user experience through his cognition.

Various properties of digital covering spaces have been substantially used in studying digital homotopic properties of digital images. In particular, these are so related to the study of a digital fundamental group, a classification of digital images, an automorphism group of a digital covering space and so forth. The goal of the present paper, as a survey article, to speak out utility of digital covering theory. Besides, the present paper recalls that the papers [1, 4, 30] took their own approaches into the study of a digital fundamental group. For instance, they consider the digital fundamental group of the special digital image (X, 4), where X := $SC^{2,8}_4$ which is a simple closed 4-curve with eight elements in $Z^2$, as a group which is isomorphic to an infinite cyclic group such as (Z, +). In spite of this approach, they could not propose any digital topological tools to get the result. Namely, the papers [4, 30] consider a simple closed 4 or 8-curve to be a kind of simple closed curve from the viewpoint of a Hausdorff topological structure, i.e. a continuous analogue induced by an algebraic topological approach. However, in digital topology we need to develop a digital topological tool to calculate a digital fundamental group of a given digital space. Finally, the paper [9] firstly developed the notion of a digital covering space and further, the advanced and simplified version was proposed in [21]. Thus the present paper refers the history and the process of calculating a digital fundamental group by using various tools and some utilities of digital covering spaces. Furthermore, we deal with some parts of the preprint [11] which were not published in a journal (see Theorems 4.3 and 4.4). Finally, the paper suggests an efficient process of the calculation of digital fundamental groups of digital images.

As the properties of living space and objects change in the digital era, furniture is also expected to change. This study starts from the question of such inclination that the digital innovation drives territories among products into the ambiguous, then tries to trace the variation of meaning against the furniture. Based on this possibility these functions, this research aims, to find out the digital functions which is preferred to be integrated with the furniture for the users of the residential space and the interface design aspects, which are considered important. preliminary survey using university students was done to extract the possible digital functions for convergence. The respondents were married women in their 20s and 30s who filled out the surveys on the internet. As a result, the specific digital convergence functions for both living and kitchen space were Identified. As major important expects for them were found functionality and controllability. Thus furniture design will expand to a concept which designs a new way of life.

In this study, the CIE RGB color space which was one of the most popular device-dependent application program in digital image processing was adopted to make the profile with the device information. The profile was applied to the digital image of a JPEG file format. The result was compared with the color reproduction of another digital image of a JPEG file format, which was made in the e-sRGB color space that had the color spaces allocated to each reproduced color of an image and device-independent colors. In this way it was investigated which color space was more appropriate for digital image processing for web printing and if the e-sRGB color space was good as a color management tool that didn't depend on a device in processing a digital image for web printing.

The efficiency and accuracy of handwriting measurement could be improved by adopting digital image processing. This study developed a computer-based Korean Handwriting Assessment tool. Second graders participated in this study by performing writing tasks of consonants, vowels, words, and sentences. We extracted boundary parameters for each letter using digital image processing and calculated the variables of size, size coefficient of variation (CV), misalignment, inter-letter space, inter-word space, and ratio of inter-letter space to inter-word space. Children were also administered traditional handwriting and visuomotor tests. Digital variables from image processing were correlated with these previous tests. Using these correlations, we established a three-point scoring system that computed test scores for each variable. We analyzed inter-rater reliability between the computer rater and human rater and test-retest reliability between the first and second performances. The validity was examined by analyzing the relationship between the Korean Handwriting Assessment and previous handwriting and visuomotor tests. We suggested the Korean Handwriting Assessment to measure size, size consistency, misalignment, inter-letter space, inter-word space, and space ratio using digital image processing. This Korean Handwriting Assessment tool proved to have reliability and validity. It is expected to be useful for assessing children's handwriting.

Contemporary society is lately going through various changes in social, economic, and cultural aspects due to rapid growth of information and computer technology. The digital revolution generated from the development of network reflects the decentralizing characteristic that connects local and personal interconnections. The following paper is designed to develop a basic understanding of digital architecture and show that digital virtual reality is not accidental phenomenon but it is actually evolved from nature and recreated in cyber space. The relationship between nature and digital architecture will be explained through the background research of how digital architecture was born and how it has been transformed. Also, it is designed to find out modern trends of digital architecture through diagrams and virtual space of hyper architecture and follow up the new phenomena appearing in the field of architecture. It is said that digital architecture is a new trend of architecture created from computer bit but all architecture that has form and shape cannot be independent of nature. Nature is the root of everything and even mechanical abstraction such as 'digital' can find its form in the immanence melted in the pure essence of nature. The research found that the nature approach of digital architecture also needs no more than 5 sequential references to find its genuine sketch as the hypertext theory shows we need only 5 sequential references to prove we are all related. Additionally, the cyber space that is become a general living space and a indispensable factor of digital architecture is a space that has obscurity and more open culture. It represents the characteristics of contemporaries in various aspects of society.
