In lighting design and lighting in the light of how the physical space rather than the amount of light metering is implemented in the same space as horizontal illuminance and luminance study of the spatial analysis as a basis for improving the quality of scientific and cognitive aspects analyzed the vertical component of the light. Vertical component of the light and the ability to interpret the information space can be secured more easily sense the brightness of a small area compared to the horizontal components of electrical energy, due to the contrast between the dark and the surrounding induce customers to public facilities or commercial space The pedestrian aids to facilitate the determination of the copper. In addition, to secure the brightness of the overall sense of space allows to have a sense of comfort to lower the tension of the space. The vertical component of light also has a deep relationship to improving the quality of light in electrical energy savings increase the accessibility of space, space, nightscape in the humanities also contribute to environmental and looking for one trillion people in the city in terms of cultural development and identity There.

The internal streets of mixed-use commercial complexes, which are the extension of urban streets, are being changed from a mediating space aiming at movement to a staying-type space according to the change of mixed-use commercial complexes. And they function as a resting place of user with court and plaza, and act as an urban public space, and accommodate an activity arising from the gathering of many people. As a result, a role of new relaxation and community space is played in the center of the city. And the aspect of publicness is brought into relief. Hence, this study is intended to examine the characteristics that the internal streets of mixed-use commercial complexes have, and furthermore, it is intended to show the planning characteristics in the contemporary mixed-use commercial complexes. With regard to the method of research, first, space configuration and role of internal streets was examined according to the change of mixed-use commercial complexes on the basic of precedent research and literature review. And the internal streets of mixed-use commercial complexes were classified into doorway part, traffic line, and open space. And the characteristics of internal streets in the mixed-use commercial complexes through the concept of architectural 'publicness' were derived as accessibility, amenity, perceptibility, openness, connectivity and symbolism. The internal streets of mixed-use commercial complexes should be changed by the space planning to secure continuity with the city on the basis of accessibility and connectivity and to reinforce visual openness in the internal streets in order to improve amenity and perceptibility, accordingly the mixed-use commercial complexes will be also born again as symbolic public space in the city. Variously changing elements to improve publicness very importantly act on the planning of internal streets in the mixed-use commercial complexes, and therefore researches should be continuously carried out.

As population inflows into the city and the traffic volume increases, a three-dimensional transportation system was developed, and as a result, the lower space of the viaduct was formed. Since the space under viaduct includes factors such as shadow, noise, vibration, and disconnection between regions, efforts have been made to prevent slumming and help form local communities by activating them. This study intends to derive analysis based on locality, functionality, and communication for a variety of access to the lower space of an overpass, and analyze cases based on the result. We have the results through analysis are as follows. First, the space under the viaduct has been turned into a slum due poor accessibility and utilization, and local residents and local government also neglected the space. However, it appears to be a space with high potential utilization. Second, by giving diversity to the lower space of the viaduct and cultivating spatial identity, the space was activated and connected with the surroundings by providing a more pleasant environment. Third, accessibility was improved by providing a complex functional and aesthetic environment, and by providing various programs that could form a community among residents, voluntary and active participation was elicited.

A gradual increase in the number of people with disabilities and the elderly in our everyday life has changed our perceptions toward them. The concept of barrier free space has been gradually incorporated into the social system and into our everyday life, and has further developed into the universal design concept so that creating an environment where all inhabitants of a city are able to enjoy the space of everyday life. Against this backdrop, this study has conducted research on how to improve the accessibility of major public spaces in Wonju, Chuncheon, and Gangneung, or major metropolitan cities of Gangwon Province. The research has been conducted under the assumption that the conditions of utilizing public spaces in those cities will not meet public expectations compared to private spaced despite being iconic cities of Gangwon Province. The field survey results show that the concept of barrier free space is reflected, to some extent, in planning and development although its role in terms of using such space is not up to expectations. In particular, the buildings and facilities built prior to the enforcement of relevant policies are found to leave much to be desired due to unsatisfactory development plans between architecture and urban public space, which necessitates improvement on relevant policies, sincere efforts of local governments, and practical guidelines that can be useful in the implementation stage. Above all, building owners and public administrations are advised to raise their awareness on the concept of universal design so that it is firmly rooted in our everyday life as one of the universal values. It should lead to the efforts of the members of local cities in providing the environment where people are able to enjoy these utilities from the perspective of promoting public welfare.

Objective : Pituitary adenomas frequently extend into the suprasellar space. After a suprasellar tumor is removed, the superiorly extended arachnoid becomes redundant and sinks down into the intrasellar space which often hiders visualization and accessibility to the hidden space behind the evaginated arachnoid. We introduced arachnoid remodeling by clipping technique, and evaluated its usefulness and safety during TSS. Methods : Total 223 patients who underwent arachnoid remodeling with our new clipping technique were included. Redundant arachnoid was clipped along the dural edge with multiple 2.6-mm titanium clips until the redundant arachnoid membrane no longer blocked the surgical route. To check for possible deterioration of hormonal function by this technique, we assessed anterior pituitary function of 166 patients who underwent arachnoid remodeling by clipping and compared this with those of other 429 control patients. Results : Our technique greatly enhanced the accessibility and visualization of intrasellar and parasellar spaces, both of which are generally hindered by redundant arachnoid during transsphenoidal surgery (TSS). We found no difference in anterior pituitary function between a clip-assisted arachnoid remodeling group and the control group, implying that this technique does not result in hypopituitarism. Conclusion : During TSS for pituitary adenomas with suprasellar extension, arachnoid remodeling by clipping technique is very useful and convenient for the management of the redundant arachnoid membrane to enhance visualization and surgical accessibility.

Today's urban spaces require diverse functions according to segmented social changes. Urban public space needs to be a field of mutual exchange, respect of diversity, and communication. According to these needs, an identity which reaches the public should be developed and realized. Therefore, this study is to present indexes for evaluating public space as a means to improve urban identity along with developing an awareness of possible problems. For this purpose, this study found out and analysed factors of evaluation indexes for the most fundamental public spaces which form cities in order to develop directions for deciding on indexes for public space and activation of that public space. An empirical analysis was conducted with the use of a questionnaire with evaluation indexes, reliability, and validity of properties of the space to be analysed and the evaluation items were tested. Based on the results, the study compared and analysed the differences between groups with independent variables (evaluation indexes) and general characteristics through a t-test. As a result, it was discovered that easy and safe accessibility in the use of urban parks as public space was statistically significant. Such results show that accessibility is the most significant factor in the use of parks.

Recently 3D GIS and its applications are getting attention increasingly as various ubiquitous-related techniques for 3D spaces are being developed. Although they call for quantitative measures such as accessibility, most accessibilityrelated studies are limited to 2D networks, not 3D indoor space levels. In this paper, we develop an accessibility index applicable to 3D models. We first examine the theory of Space Syntax which has been developed and used to measure the connectivity or relationships between spatial segments in urban or architectural environments. Then, we expand the principle to a more general form so it can be applied to both street and indoor space levels. We incorporate different types of impedances in moving between places including distances, turns and transfers between floors into the traditional Space Syntax that measures the spatial depths solely based on the structural forms. Finally, we illustrate the use of the proposed measure comparatively using a campus building.

This study examines whether and how ages of child affect accessibility experiences of women and men differently. Space-time accessibility measures based on Time-geographic framework with activity-travel diary datasets in Portland Metro, US were calculated using GIS-based geocomputation, and spatial-temporal patterns of accessibility of dual-earner couples by ages of their youngest child were compared. The results are as follows. (1) Although more women than men work part-time, which would render women more spatial-temporal autonomy, accessibility levels of women are not higher than men's. It implies that there exists another constraint placed on women which largely stems from gender inequality. (2) It is distinctively women with child under age 6 of which accessibility spaces are found to be restricted doser to home compared to men. Women with no child or with child aged over 6, however, show more or less similar spatial-temporal patterns of accessibility with men's which are quite unvarying regardless of parental status and their child age. Women's accessibility experiences characterized by spatial-temporal entrapment, thus, can be seen as problems associated with gender rather than sex. (3) Intensified spatial-temporal entrapment of women with young child are associated with the significant spatial pegs shaping their accessibility spaces, which are located much closer to home compared to men's: workplaces and child's daycare centers.

This study examines room assignments to improve accessibility in a university dormitory depending on the student grade, taking into account frequency of using a certain common space. An integer programming model is presented to minimize the total moving distance from the common space to the students' rooms for accessibility. The model also constrains the maximum capacity of a room, and disallows different grade students to be assigned to the same room. This model is similar to a facility location problem used widely in the supply chain management field. Applying our optimization model to a small group at the dormitory of Unversity A as the case study, our results indicate that lower grade students are assigned rooms closer to the common space due to their higher frequency of using that space to guarantee high accessibility. Moreover, if higher grade students are prioritized to select their rooms, we suggest an objective function that imposes a penalty in cases when lower grade students select rooms with priority. Based on the results obtained, we propose assigning rooms to students in a dormitory by considering their complex requirements and convenience to use the common space.
