Various residential patterns, which can accommodate ever-changing modem lifestyles, are increasingly needed. On the residents' demand for flexible space, mote research should be conducted on the apartments built by the concept of flexible space. In this study, apartments of 40-60 pyeong in size built in the region of Seoul, between 1998 and 2007, are analyzed in terms of the flexible types and the unit plan composition. To reflect the changes in people's perception of residential quality-preference for a residence with a good view, over for the direction that a residence faces, more rooms are placed on the front bay. From the analyses of this study, flexible unit plans are classified into 6 types; and it was found that, as the size of apartments gets larger, the livingroom and the dinning room tend to be placed on the front bay. After grouping rooms with a similar function into the spatial zones of the master bedroom, children's room, the livingroom, and the dinning room, flexible types are analyzed in terms of the location of rooms. The results of this study will be able to contribute to establishing flexible housing culture that can accommodate the changing needs of residents.

The concept of construction information systems (IS) is very comprehensive and subjective. Acronyms in relation to the construction IS may include BIM, CIC, IT, nD-CAD, ERP, CALS, KM and so on. These terminologies are used in a somewhat mixed way causing possible misunderstandings in research and practice of construction information systems. Moreover, ever-changing construction business environment has widely affected the roles and methods of utilizing construction IS. Examples of these changes are dissemination of alternative project delivery systems, global standardization under highly competitive overseas market, and advancement of information and communication technologies. In this context, the purpose of this paper is to propose a high-level framework for information systems in the construction industry. Several different concepts in the area of construction IS were investigated first in order to identify the major variables of the framework. Trends of research and real-world implementations were then analyzed to support the rationale of the variables. Finally, a framework was proposed by re-arranging the relevant issues. Findings of this paper indicate that different acronyms commonly share many similar concepts in their definitions, however, in each acronym, the motivations and approaches to implementing construction IS are very different. Different approach can provide maximum effectiveness, while overlaps may happen causing practical inefficiency.

It is quite a necessity for the small and medium corporations(Abbre : SMC) to have information technology in order to survive in ever changing global business environment . Especially recently, the importance and uses of Internet have greatly increased by SMCs facing changing environment. This thesis aims to propose various application alternatives of Internet through the analysis of the Internet uses by SMCs. For the analysis, questionaires were distributed nationally to 126 small and medium corporate entities, and 64 out of 82 retrived questionaires have been used for the analysis. The analysis revealed several notable points related with Internet applications by SMCs that , although SMCs strongly feel the need for the use of Internet. -the level of recognition for the existence of the Internet was relatively low -the time used was also at low level -the job which uses Internet was mainly marketing related -and the fields applied were concentrated in those of search and e-mail. The benefits which are derived from the use of Internet include swift provision of technological information to SMCs ,improvement of active interchanges of information through the whole relate networks, strengthened promotion of products made by Internet to promote smooth communications (among related divisions or personnels), to automate work systems , and to systemizestrategic management planning process etc. Consequently, it is expected that, althgough the level of application of Internet is quite low, Internet can be served as a source of information technology and futher as a weapon to better combat strong competition through various supports at government level, since small and medium corporations feel its strong need for Internet.

Polygenic variation of sternopleural bristle number was investigated at the whole chromosome level in a natural population of Drosophila melanogasfer. Fifty pairs of second and third chromosomes were analyzed at $25^\circ{C}$. Since environmental factors such as temperature influence polygenic expression of quantitative traits, whole chromosomal effects of 28 pairs from the larger original sample were measured under cycling temperature, a $10-30\circ{C}$ cycle in 24 hours, to reveal any polygenic alleles whose effects might be masked under the constant temperature. While third chromosomes typically showed a larger contribution to polygenic variation in both environments, second chromosomes showed greater sensitivity to environmental changes. Cluster analyses of second and third chromosomes produced a limited number of clusters. Such a small number of cluster's implies that there may be a small number of genes, or quantitative trait loci (QTLs), having large effects on phenotypic variation. The genetic structure assessed under constant temperature, however, did not show any correlation with the structure under cycling temperature. The discrepancy could be caused by independent response of each polygenic allele to temperature changes. Thus, polygenic structure in natural populations should be thought of as a temporally changing profile of interactions between gene and ever-changing environment.

Aires Mateus Architects is one of the most well-known Portuguese architects after $\acute{A}lvaro$ Siza and Eduardo Souto de Moura. The studio shows clear design methods in which the relationship between solid mass and void space are creatively inter-connected. Subtractive transformation of form is the fundamental aspect of this relationship. Most of Aires Mateus' projects were designed based on the subtractive method. Although subtraction can be seen as architectural formal presentation, in Aires Mateus' cases, there are deeper logics, strategies, and meanings. Not only to create a form, subtractive method has been flexibly used to organize and compose different programs and spatial atmosphere. To examine this hidden dimension of Aires Mateus' unique design process, 5 case projects were selected and analyzed in detail based on program, light & visual-perception, and site's placeness. From the case study results, it is found that there are much deeper role of subtraction: relationship between solid-void are constantly changing to generate serviced and servant spaces, there are central spaces that are contrast against the complexity of exterior forms, aiming to build an archetypal form that transcends ever-changing time, ambivalent balance between universality and peculiarity in the genealogy of contemporary architecture. The study concluded that the unique characteristics of subtraction method as design organization have various possibilities that can apply on other architectural and interior projects which would have similar ideas and circumstances.

The business models has a great impact on the successful management of enterprises. Business environment has been shifting from industrial economy to knowledge-based economy. Enterprises go through numerous trials for successful management in the changing environment. Along with trial tests, research areas have been growing simultaneously. Although many researches have been conducted with regard to business models, it is very insufficient to systematically analyze the knowledge flow of research. Accordingly, successive researchers who want to study the business model may find it difficult to establish the orientation of future application research based on understanding the process of changing the knowledge structure that have accumulated so far. This study is intended to determine the current state of the business model research and to understand the process of knowledge structure changes in keywords that appear in 2,667 business model articles in the SCOPUS database. Identifying the knowledge structure has been completed through social network analysis, a methodology based on the 'relationship', and the changes in the knowledge structure were identified by classifying them into four different periods. The analysis showed that, first, the number of business model co-author increases over time with the need for academic diversity. Second, the 'innovation' keyword has the biggest center in the network, and over time, the lower-rank keyword which was in the former period has emerged as the top-rank keyword. Third, the cohesiveness group decreased from 12 before 2000 to 5 in 2015 and also the modularity decreased as well. Finally, examining characteristics of study area through a cognitive map showed that the relationships between domains increased gradually over time. The study has provided a systematic basis for understanding the current state of the business model research and the process of changing knowledge structure. In addition, considering that no research has ever systematically analyzed the knowledge structure accumulated by individual researches, it is considered as a significant study.

Congestion is a growing concern of many global cities and the demands on Infrastructure services within a locale coupled by the rising expectations from the growing population places stress on these cities. This entails the ability to build a sustainable community that requires an understanding and recognition of Population growth, changing demographics and the ever changing urban development on both a macro and micro level. Infrastructure is an integral part of Australian economy, particularly the 'Infrastructure Assets Management' which highlights the importance towards the development of sustainable communities for Melbourne's future. Melbourne 2030 is a comprehensive representation of government's response to a wide-ranging population growth within Melbourne metropolitan and surrounding areas. Urban plan and specific Infrastructure Assets Planning needs not only to provide sufficient Infrastructure to a community, but it must also be efficient and innovative so that it produces an optimised management system. A system that incorporates engineering techniques that will be sustainable for decades to come by maintaining an acceptable level of services to its intended community in an effective manner, which also strengthens service delivery. The fundamental challenges for optimization of Infrastructure with the Melbourne urban plan is, the ability to manage and sustain maintenance of Infrastructure to provide the acceptable level of service required by the community in a most effective manner which also strengthens service delivery to contribute towards Melbourne 2030. This paper particularly investigates some of the fundamental issues within the Melbourne urban plan such as Infrastructure Asset Management, AusLink and the Australian Road Management Act 2004, which the Governments at all levels must deal with to provide an economically viable solution to the changing Infrastructure so it may suits the needs and services the strategies of a metropolis.

It is known that the role of informal support for elderly women is critical to their physical and mental health, adjustment in old age, and their overall life satisfaction. Elderly women's situation such as social losses, widowhood, living alone, and geographic relocation etc. may result in a need for more informal supports for elderly women's health than ever before. Particularly, women's same-sex friendships were rated higher for overall quality, intimacy, enjoyment, and nurturance. Unlike a generally accepted notion that later life for women is a time of isolation and loneliness, elderly women tend to maintain and reestablish their friendship regardless their marital status and living situation. Although studies on informal support for elderly women were inconclusive in many ways, elderly women's friendship tends to be stable despite of changing health status and life events. The relative importance between daughters and friends was also controversial. This study suggests that more research with reliable measurements is necessary for the practical prevention and intervention program of elderly women's health on this issue.
