This thesis aims to study the space concept of the constructive mode in the work space of the postmodernism artists since 1970s. According to the changing view of the world artists, they are searching for the characteristics of having the parameter of formative organization on how they are related to the constructive system which represents the work styles. First, this study searches for the theoretical approaches of the constructive system and parameters that were studied by Le Corbusier - the module concept as the meaning of order system being used for the basic formative construction Second, when it is regarded as a formative construction in making art as the'principles of organization'(the law of living form), which was defined by Suzanne Langer in the formative theory as the organized structure shown in growth structure in mu and ecological system, the principles governing the module rules were arthmetically analysed art-work space through the dynamic symmetry of Jay Hambidge. Therefore, this study shows the principles working on the parameters for new formative organization as follows: First, the module in the work space should be designed and built from the dynamic symmetry. Second, the module should satisfy the human needs that it must be acceptable, efficient, flexible, which are the necessary and sufficient condition for the dynamic symmetry. Third, the dynamic symmetry which has the principle of Reciprocity and the principle of Complement as its primary construction principle has the common properties and the reciprocity in the construction of the work space and when it has the self similarity, it segments organically the total space without damaging the continuum.

Steam turbines, gas turbines, multistage centrifugal compressors are operated over the range of the first critical speed. In these rotors flexible rotor balancing technique is necessary. In such balancing, influence coefficients are measured by rotating a rotor with trial weight. But for the large rotor, the measurement of influence coefficient takes much time and it reduces the cost efficiency. In this paper the new influence coefficient with rotation of rotor is proposed. First the theoretical background of the method is presented and it is applied to the simple flexible rotor model. Then the experiments are performed and the results of presented method are compared with those of analytical method. By using the obtained influence coefficient, balancing of the flexible rotor is performed.

International investment has been gaining the importance in the economic growth, employment and technological spillover for many countries at the time of unrestrained flow of the production resources, inter alia, the capital. International investment is prerequisite for Korea to overcome its resource-scarcity. This paper studied some contentious issues of international investment and attempted to suggest negotiating position for Korea on future FTAs. We have made theoretical research of the issues and derived common denominators from four previous FTAs which Korea has concluded. Based on both theories and evidences, we suggest that Korea be ready to have more open attitude for incoming international investment, that is, foreign direct investment(FDI) in future FTA negotiations although Korea should have rather flexible strategy on international investment issues, on the basis of the reciprocity.

Computerized visual database construction of architectural precedents has just begun in some research institutes in the world. In Korea the first visual database has shown its testl version by S architectural design firm in september 1996. In this article the author discusses the historical contexts and the recent computerization cases, the traits, the uses and the limits of architectural visual database system of precedents. The forms and contents of data fields in two cases are compared with a focus on the description of architectural traits of each data entry. Compared to the KIA format, the S database has better performance for architectural design reference because it collects more pictures and drawings and larger texts for the field of architectural chracteristics. But this latter also is constrained by its capacity of memory and so lacks the reciprocity of the DOORS in the Graduate School of Design, Harvard University. A visual database system which has more flexible allocation of memory and respondent with the users is yet to be prepared. But this system also should be maintained by some experts in architectural history, theory and criticism, because their knowledge is essential for selection of precedents and revision of the data description. A full-fledged electronic visual database in architecture will not only save much effort for the architect, but also will change the architects' design behavior. Nevertheless this does not mean the automatic promotion of architects' creativity.

This study explores the types of relationships between 410 adult children and their elderly parents based of exchange theory and the Konstanz model. In terms of the exchange of emotional, instrumental, and economic support based on exchange theory, the types of relationships identified included "support offers," "reciprocity," and "support benefits." In terms of conflict, intimacy, support offers, support benefits, and support obligations for adult children based on the Konstanz model, the type of relationships with the father included "an intimate exchange," "conflictual distance," "a conflictual sense of duty," and "a flexible exchange." The type of relationships with the mother included "an intimate exchange," "conflictual distance," "separate distance," and "a conflictual offer." There were no distinct characteristics of relationship types based on exchange theory. However, there were differences in characteristics of relation types based on the Konstanz model by gender. These results have important implications with respect to the Western model.

It is required to expand area of inter-Korean economic cooperation, being limited to non-military field, to military field and then, to positively promote arms control in order to establish foundation for peaceful reunification in Korean peninsula. Reasons why arms control has not been promoted between South and North Korea in the meantime were such original factors as follows; (1) limit of confidence building between the South and the North, (2) functional limit of arms control itself, (3) institutional structural limit between the South and the North, (4) environmental limit at home and abroad. It is necessary to get out from existing frame and to seek a new paradigm in order to overcome above factors and to realize arms control between the South and the North. First, it is required to have prior political dialog at the South-North high-level talks in order to promote arms control and to exercise 'strategic flexibility' during negotiation and promotion process. For this, 'flexible reciprocity' has to be adopted in compliance with situation and conditions. Second, it is necessary to get out from existing principle of 'confidence building in advance and arms reduction later' but to seek the 'simultaneous driving principle of confidence building and arms reduction' as an eclectic approach. Namely, based on reasonable sufficiency, it is required to promote military confidence building and limited arms reduction in parallel, which is a lower level of arms control. Third, as an advisory body of Prime Minister's Office, it is necessary to install an organization exclusively responsible for arms control and to positively handle arms control issue from the standpoint of national policy strategy. If the South-North high-level talks take place, it is necessary to organize and operate 'South-North Joint Arms Control Promotion Board (tentative name)'. Fourth, it is required to exercise more active diplomatic competence in order to create national consensus on necessity of arms control for peaceful reunification and to form more favorable international environment. Especially, it is necessary to think about how to solve nuclear issue of North Korea together in collaboration with international society and how to maintain balance between ROK-US alliance and Sino-Korean cooperation relations.

The purpose of this study is to examine how providing care to grandchildren and the continuity of care affects the grandparents' perception on old-age support. Specifically, in this study, providing care is divided into three continuous types: did not provide care, provided care at one point in time and provided care at two points in time. This is done to investigate how the duration of providing care influences the perception on old-age support. The results show that grandparents providing care to their grandchildren prefer to reside with their own children in the future more often than those who do not provide care to their grandchildren. Furthermore, grandparents providing care to their grandchildren during two-time points and grandparents providing care during one-time point prefer to reside with their adult children in the future more than grandparents providing care not once during two-time points. Interestingly, grandparents who provide care to grandchildren during two-time points prefer to reside with their children in the future more frequently than grandparents providing care during just one-time point. These results suggest it is likely that grandparents recognize providing care to their grandchildren as an insurance in care and support for themselves in the future. Additionally, these results suggest that the family plays an efficient and flexible role to meet needs of family members through a reciprocal relationship in Korean society where the public sector is weak. These findings have suggested theoretical implications.
