For the evaluation of the mobile robot performance in complex environments, the experimental approach in an actual physical environment has been commonly taken. In the physical experimental approach, however, it is quite difficult to define the proper environment for the evaluation due to the lack of commonly agreed characteristics of the test environment. Particularly the number of combinations of types and physical parameters of the obstacles that the mobile robot is expected to deal with is practically unlimited. In an effort to simplify and improve the effectiveness of the evaluation process, we propose an evaluation method using decomposed environmental elements, where we evaluated the performance of the robot for a small group of simple and decomposed obstacle components, for examples projection and slope, instead of a large group of complicated random obstacles. The paper describes a set of simple obstacle models and performance parameters that we have chosen for the effective evaluation process. As an alternative to the physical experimental evaluation approach, in this paper, we used a virtual evaluation environment where the robot and the physical test environment has been modeled using a commercial multi-body dynamics analysis packaged called RecurDyn.

For the comfortable housing life, comfortable and pleasant urban environment should be created for the people living in house and in city. There are lots of environmental conditions in city affecting house and life. Also most of all the noise pollution have been become major factor that makes people's life uncomfortable. Recently soundscape researches have been performed to create comfortable urban environment and various studies on the evaluation of urban environmental sounds are now undergoing. This study aimed to analyse the subjective characteristics through the subjective evaluation to the sounds measured with physical parameters and eventually to find out alternative evaluation method for urban environmental sounds. Adjectives applied to previous studies were used for the subjective evaluation and sound sources recorded in specific places were presented with picture at the same time. As a result, new physical parameters such as Lmax, Unbiased Annoyance, G, N and EmT have a feasibility to evaluation of urban environment sounds in terms of acoustic comfort.

While the operator's working environment employs the digital devices and technology which are not be fully digitalized due to its technical constraints, it has been changed to the hybrid environment in which digital and analog elements are combined. The hybrid environments need to study its characteristics and the guidelines for the proper design and evaluation purpose. This paper describes the characteristics and evaluation guidelines for hybrid environment through studying the characteristics of digital and analog environment based on the related human factor guidelines and literatures. The result of this paper would be applied for the human machine system such as main control room in nuclear power plant working under hybrid environment. And also, it may be applied for the evaluation of the generic human working environment which digital and analog elements are jointly used.

Development of index for evaluation of environmental nature and its application for the purpose of construction of industrial complex with environmentally friendly. Industrial complex comes to be recognized as a disgusting zone according to the increasing environment consciousness of residents. And the objection about the exploitation of geographically unwanted land site is increased during development process and it is possible to cause Nimby phenomenon. Therefore, ecology and environment-oriented strategies tends to be adopted for industrial complex development. Furthermore, the maximization of profit mainly directed by enterprises as of today cannot guarantee its future and the efforts of adopting environmental constancy and harmony as a new objective are made progressively. For the development of city and region, in particular such as residence complex, farming and special city, the discussion of environmental consistency, new paradigm with environmentally friendly is briskly under progress, but the relevant discussion for the development of industrial estate is not done so much. Just only few studies are realized from the viewpoint of industrial ecology but its level remains in the understanding of the concepts and presentation of development direction. This study is to prepare for the foundation of the construction of industrial estate with environmentally friendly under the current condition of Korea against coming future environment era and to try to develop of evaluation range and index which are the basis of evaluation of environment. I applied the above evaluation index to the residents of actual industrial estate to understand their consciousness of decreased environment. And I obtained 7 evaluation ranges and 37 evaluation indexes for the relevant residents. Among them, I get the value less than the average in 19 index items. And they represent very sensible reaction about environment pollution including decrease of waste materials. This study has several limits but is meaningful in that the development of evaluation index for environmental nature in industrial complex is done, and that the basic discussion of the plan and design for environmentally friendly industrial estate is made under the above evaluation and that 37 evaluation items are applied to the reality.

Purpose: The purpose of this study is to evaluate the work environment and job satisfaction of hospital workers and to assess their effects on quality of services under the national long-term care hospital evaluation (hereafter, national evaluation), which has implemented since 2008. Methods: A self-administered survey was conducted on 178 hospital workers' at 18 hospitals in Chungcheong province, Korea. Survey questionnaires include questions about respondent' awareness of the national evaluation and any change in work environment and job satisfaction under the national evaluation. We used a path analysis to assess the effects of work environment and job satisfaction on quality of services. Results: Results showed that the effects of the national evaluation on work environment and job satisfaction were positive, which, in turn, leads to better quality of services. Improvements in the work environment under the national evaluation have resulted in increased job satisfaction. High scores for job satisfaction showed a significant association with the quality of services provided in long-term care hospitals. In addition, the national evaluation itself had a positive effect on improving quality of services. Conclusions: In order to facilitate quality improvement activities under the national evaluation, it is suggested that workers be provided with education and training. Continuous efforts to improve work environment and to enhance job satisfaction would lead to provision of better quality of services in long-term care hospitals.

The natural environment of the modern society does not simply reflect damage, but is a complex and grave reality that threatens the Earth. To solve this problem, various aspects related to the natural environment have been explored around the world, and a number of studies are ongoing to balance the development and preservation of the natural environment in Korea. However, no clear category exists for the natural environment and the related terms are ambiguous, rendering the overall evaluation system is in efficient. Therefore, the present study attempted to set the scope of application of a comprehensive evaluation system based on terms similar to the natural environment, concepts of the natural environment viewed from a value-based perspective and a capacitive perspective. In addition, by examining the concept of ecosystem services, a conceptual model for efficient application of the evaluation system of the natural environment through the association between categories of the natural environment is presented to derive implications for practical operation in the future.
