In this study, our purpose is to identify a causal relationship in consciousness relating to the public involvement for current road improvement projects in Seoul Some of hypotheses about causal relationships among the psychological factors are assumed to develop a structural equation model. This model includes latent variables determining the consciousness relating to public involvement procedure, such as distrust feeling for administration (public sector) the knowledge and satisfaction about the road project, and the comprehensive faculty on the public involvement. The estimated model indicates that these assumed hypotheses are proved and that the administrative distrust strongly determines the consciousness as well as understanding of the road project and the knowledge of PI procedure.

The purpose of this study is to develop conflict management considering justification of planning decision by public involvement (PI) in the context of Korea as an approach to prevent conflicts for railway projects and to achieve consensus building between public and governments. In this study, to evaluate the effectiveness of conflict management in the process of railway planning, we examined the before and after survey on the light rail transit (LRT) planning that was previously conducted. We first conducted estimation on the causal relationships among factors related to acceptance of LRT planning by structural equation model. The estimation results show that conflict management activities and acceptance are positively related. We also discussed as follows: the level of recognition of railway project influences positive effects regardless of conflict management activities, the most important factor with respect to the acceptance is awareness for planning necessity.

The objectives of this paper are to introduce the PI(Public Involvement) in railway project and case study about public participation in decision making process for Ko-Yang light rail line development, besides to emphasize the importance of information considering the difference of resident location, regional character and so on are investigated before and after public participation. As the results, it was clarified about PI activities styles that consensus is not achieved in Ko-Yang public participation, the psychological factor such as the knowledge and satisfaction, receptivity about light rail project strongly is affected to making decision.

Recently, several national construction projects such as Chunsung Mt. section of Kyungbu High Speed Rail or Sapae Tunnel of Seoul Outer Ring Road have been delayed or suspended due to the objections of residents or environmental organizations. Considering the development of democracy, increased public participation and interests on environmental issues in Korea, the generation of these social conflicts may be natural phenomenon. However, it is necessary to find measures to effectively implement major construction project and save costs related to social conflicts. In this paper, PI techniques in the United States are investigated and in comparison, the weakness and improvement plans for Korea's current public participation system have been suggested.

Infrastructures in Japan constructed mostly in high economic growth period become elder & elder, and the troubles & accidents caused by the aging increase. Though investment for the renewal is necessary, the shortage of public fund delays the action. Besides, we expect the decrease of the population that means the decrease of the engineers who take care of social infrastructures. Thus, it is necessary for us to develop Advanced Management system of social Infrastructures (AMI) to realize the efficient and economical operation. Our concept of AMI consists of using ICT, PI (Public Involvement) and establishment of O&M diagnosis system. We expect AMI will support to realize the appropriate repairing, preventive maintenance based on the actual performance, accidents & dangerous experience and education & training of the workers. In this paper, development of AMI for the waste disposal facility as a first example of infrastructures will be shown.

Chlamydiae, obligate intracellular bacteria, are associated with a variety of human diseases. The chlamydial life cycle undergoes a biphasic development: replicative reticulate bodies (RBs) phase and infectious elementary bodies (EBs) phase. At the end of the chlamydial intracellular life cycle, EBs have to be released to the surrounded cells. Therefore, the interactions between Chlamydiae and cell death pathways could greatly influence the outcomes of Chlamydia infection. However, the underlying molecular mechanisms remain elusive. Here, we investigated host cell death after Chlamydia infection in vitro, in L929 cells, and showed that Chlamydia infection induces cell necrosis, as detected by the propidium iodide (PI)-Annexin V double-staining flow-cytometric assay and Lactate dehydrogenase (LDH) release assay. The production of reactive oxygen species (ROS), an important factor in induction of necrosis, was increased after Chlamydia infection, and inhibition of ROS with specific pharmacological inhibitors, diphenylene iodonium (DPI) or butylated hydroxyanisole (BHA), led to significant suppression of necrosis. Interestingly, live-cell imaging revealed that Chlamydia infection induced lysosome membrane permeabilization (LMP). When an inhibitor upstream of LMP, CA-074-Me, was added to cells, the production of ROS was reduced with concomitant inhibition of necrosis. Taken together, our results indicate that Chlamydia infection elicits the production of ROS, which is dependent on LMP at least partially, followed by induction of host-cell necrosis. To our best knowledge, this is the first live-cell-imaging observation of LMP post Chlamydia infection and report on the link of LMP to ROS to necrosis during Chlamydia infection.
