An approximate method of normal coordinate idealization for use in nonlinear R/C frames has been developed. Normal coordinate apporaches have been used for nonlinear problems in the past, but they are not received wide acceptance because of the need for eigenvector computation in each time step. The proposed method cicumvents the eigenvector recalculation problem by evaluating a limited number of sets of mode shapes in performing the dynamic analysis. Then the predetermined sets of eigenvectors are used in the nonlinear dynamic analysis, repeatedly. The method is applied to frame structures with ductiles R/C elements. The plastic hinge zones are modeled with hysteresis loops which evince degrading stiffness and pinching effects. The method is applied to frames with local nonlinearities. Efficiencies and accuracies of the method for this application are presented.

An individual's eating behavior reflects not only the eating habits of past but also the type of them which characterize the next generation's. A great difference had been observed between western and oriental food lifestyle. By the frequent contacts with each other, however, current oriental food lifestyle is apt to be much westernized. But the food culture of Chosun tribe in Yenbeun, in spite of natural, local, cultural and social demographical factor of change, has been almost preserved in basic convention for 140 years. It can be observed in choice, acceptance and fixation of food that the management of traditional food and eating behavior has been subtained preserving their unique tradition in Chosun tribe.

This paper presents the empirical research results conducted in a Swedish care organization for elderly and handicapped. The objective of the research was to empirically assess the implementation and practices of a quality system (ISO 9000) from an organizational change and development perspective. The empirical data were collected through multiple methods; interviews were carried out with key-persons and leadership in the organisation and surveys were conducted to all employees. Interactive methods have been applied to various groups in the organisations e.g., directors, supervisors, and the leadership of the quality project and the local politicians. The empirical findings indicate, among others, that the implementation processes were received and perceived differently in the different parts of the care organisation due to different leadership strategies and employee involvement policies. Other critical factors such as acceptance, resistance, motivation, commitment, the role of leadership, learning possibility, etc. have also been investigated, analysed and discussed. Finally some recommendations on how to approach organisational change as well as strategies for implementing a quality system in the care sector are presented.

Six models of operator seat supplied to local tractor manufacturers were tested in the laboratory in accordance with ISO 5007 and 78/764/EEC. No models out of the six met the allowable damping and transmissibility performance criteria of both ISO 5007 and 78/764/EEC. From the ISO criterion standpoint, one model failed in damping performance and 4 models in isolation performance. From the 78/764/EEC criterion standpoint, 4 models failed in damping performance and 4 models in isolation performance. However none of them failed in all of the criteria, either. Each model met the one acceptance criterion but failed in another. This indicated that operator seat must be improved to meet the current ISO 5007 or 78/764/EEC and the exposure limit value that will be enforced in EU tractor market from 2014 by EU Directive 2002/44 EC.

Ultra Wide Bandwidth (UWB) spread-spectrum techniques will playa key role in short range wireless connectivity supporting high bit rates availability and low power consumption. UWB can be used in the design of wireless local and personal area networks providing advanced integrated multimedia services to nomadic users within hot-spot areas. Thus the assessment of the possible interference caused by UWB devices on already existing narrowband and wideband systems is fundamental to ensure nonconflicting coexistence and, therefore, to guarantee acceptance of UWB technology worldwide. In this paper, we study the coexistence issues between an indoor UWB-based system (hot-spot) and outdoor point to point (PP) links and Fixed Wireless Access (FWA) systems operating in the 3.5 - 5.0 GHz frequency range. We consider a realistic UWB master/slave system architecture and we show through computer simulation, that in all practical cases UWB system can coexist with PP and FWA without causing any dangerous interference.

This study suggests 5 evaluation criteria (safety and technology, environmental impact, economic feasibility, social factors, and institutional factors) and 24 evaluation indicators for a NFC (nuclear fuel cycle) derived using factor analysis. To do so, a survey using 1 on 1 interview was given to nuclear energy experts and local residents who live near nuclear power plants. In addition, by conducting a factor analysis, homogeneous evaluation indicators were grouped with the same evaluation criteria, and unnecessary evaluation criteria and evaluation indicators were dropped out. As a result of analyzing the weight of evaluation criteria with the sample of nuclear power experts and the general public, both sides recognized safety as the most important evaluation criterion, and the social factors such as public acceptance appeared to be ranked as more important evaluation criteria by the nuclear energy experts than the general public.

The aim of this study is to develop suitability site indicator of urban-rural return to fishing and to analysis priority of the indicators. The study is based on literature review, expert survey and AHP(Analytic Hierarchy Process) methods. This study found 5 factors(natural environment, acceptance environment, social overhead capital, economy, fishing environment) and 21 detail variables. as a result of AHP, fisheries resources, acquisition convenience of fishing license, income(except fishing), attitude of local resident, one-person household income, high income fishing were showed high priority. This result indicate that economic foundation is most important factor for suitable site of the returning.

This paper will concentrate on how various particular Southeast Asian conditions created a distinct Southeast Asian cultural identity despite a very challenging geographical and historical diversity in the region. The paper will argue that Southeast Asians demonstrate an ability to adapt to changes and new values but also exhibit fatalism through a very high degree of passive acceptance to political and other changes that affect their society. The paper identifies a degree of environmental and geographical uniqueness in Southeast Asia that shapes context and gives rise to very distinct cultural traits. The historical transformation in the region brought about by colonialism and nationalism, combined with this geographical and political make-up of the region, had an immense impact on Southeast Asian society as it fostered adaptability. Finally, the political transitions brought about by various conflicts and wars that continued to affect the area in rapid succession all throughout the 20^th century likewise contributed immensely to a local Southeast Asian fatalistic response towards change. Historically, Southeast Asia demonstrated these socio-cultural responses to such an extent that these are argued to permeate the region forming a distinct aspect of Southeast Asian culture.

As offshore wind farms are developed, the importance of cooperation with stakeholders such as fishermen from the initial phase is gradually increasing. This study developed a methodology that can promote the involvement of fishermen in the site feasibility review process. The spatial scope is Gunsan City, which is establishing an initial offshore wind project strategy. A survey was conducted for representatives of 12 fishing villages on the location preference for offshore wind farms. As a result, fishermen suggested negotiable or absolute opposite locations by examining a local sea map. Location preference seems to depend on the degrees of vitalization of fisheries using vessels. This study shows that fishermen can have reasonable opinions according to the location, not unconditionally, in initial discussions on offshore wind power. Investigating stakeholders with various positions is essential, and adjustments are needed for conflicting points in the future.
