The reality of domestic prints neither possesses an objective standard of standard density nor a spectrophotometric method in regard to process ink. As a result, it creates a difficult communication between a designer and a Prepresser as to estimating the color of reproduction prints. There was an experiment on paper, ink, and printing company to obtain the standard point. The result shows that paper has minimum effect on color reproduction as opposed to ink and different printing companies, which had a great effect. The purpose of this paper is to confirm how different the color reproduction properties of prints are using densitometer and spectrophotometer for three different ink companies. The process color inks of three different companies were used under the same printing environment in this experiment.

For effective and efficient environmental management, developed countries, such as the Netherlands, UK, Australia, Canada, and United States apply ecological risk assessment, and they have an autonomous risk assessment methodology to protect native receptors. In this study, soil ecological protective concentration (EPC) of cadmium in Korea was derived using Korean ecological risk assessment methodology. The soil EPC of cadmium was calculated using probabilistic ecological risk assessment based on species sensitivity distribution. The soil EPC was calculated according to land use for residential/agricultural and industrial/commercial purposes. The chronic soil EPCs for residential/agricultural and industrial/commercial lands were derived to be 1.58 and 9.60 mg/kg, respectively. These values were similar to soil EPC of European Commission, the Netherlands, UK, and Canada. However, these values were lower than the established Korean soil standard, because the current soil standard was based on human risk. Therefore, the impact on an ecosystem when establishing environmental standard should be considered.

Diverse problems in wind environment has occurred through rapid urbanization and growth of high-rise building numbers, This study aims to propose the CFD (Computational Fluid Dynamics) simulation method and evaluation standard of wind environment in site planning of high rise apartment housing. The CFD simulation method proposed in this study is not existing detail simulation, but it is the method that a designer can correct and develop the design through immediate evaluation of design options in concept design phase. Therefore, the proposed CFD simulation method of wind environment in this study uses the BIM based CFD tool in which the 3D model in concept design phase can be used as for the CFD simulation. In this paper, the study examines existing evaluation standards of comfortableness level in wind environment for pedestrian near buildings, and selects new evaluation method which is possible to apply to the proposed CFD simulation method. In addition, it is to examine calculation time-spending and appropriate mesh division method for finding CFD result which is useful to find the best design options in aspect of wind environment in concept design phase. Furthermore, it proposes the wind environment evaluation method through BIM based CFD simulation.

In these days, water environment is getting threatened by a variety of toxic pollutants discharged from industries. However, environmental standards and regulations in Korea may be in straitened circumstances to protect the water environment from it. Therefore, the purpose of this review is to compare the management state of the toxic substances in water environment and to present the framework for deriving water quality criteria in USA and Japan. To conserve the water environment from the toxic pollutants more efficiently, the following considerations could be suggested in standards and regulation in Korea. Firstly, there should be consistency of regulated pollutants in drinking water quality standard, water quality standards and permissible wastewater discharge standards. Secondly, in case of deriving the water quality standards, it is required to consider the conservation of the aquatic ecosystem as well as the protection of human health. Finally, it is indispensable to make risk-based approach in management of toxic pollutants in water environment.

This study is to realize the importance of the therapeutic environment of nursing facilities for elderly people; to comparatively analyze the therapeutic environment elements of the facilities in Gwangju, Jeonnam area, Seoul, and Japan by classifying the therapeutic environment elements according to two aspects on the basis of preceding studies; and to find out the differences among the three regional groupsnaFirst, all therapeutic elements were put together on the basis of two preceding studies based on the two aspects. Second, an expert group was organized primarily with architects and care-givers to find out the therapeutic environment elements of nursing facilities for elderly people with dementia, and to draw up an evaluation standard. Third, the regional differences were analyzed, by comparing the distribution of therapeutic elements of the facilities in Gwangju-Jeonnam area, Seoul, and Japan, through the found therapeutic environment elements. Consequently, eighteen therapeutic environment elements were found out of total 32 elements, and the elements were classified into nine factors based on the meaning of each element. The therapeutic environment elements were showed highest in Japan, and lowest in Gwangju-Chonnam area according to the comparative case analysis based on the nine factors. Especially, there were great regional differences in terms of awareness, safety, orientation, privacy, and freedom of choice.

This paper aims to provide a basic framework to make a regional plan for the environment-friendly agriculture. To prepare the regional plan is mandated by the Environment-friendly Agriculture Promotion Act of 1998. Here is proposed the input/output analysis framework, which includes the shifts of fertilizers, herbicides, pesticides, and livestock manures Basically, the discharged amount of polluted elements means the difference between the amount of the elements entered into the crop and livestock sectors and the amount of the elements absorbed or used by the crop and/or livestock. A few suggestions are offered for better regional environment-friendly agricultural plan. The foremost important thing is to establish a data collection system. The \"Green Accounting System\" is suggested. It is also crucial to create a standard guideline or manual which Provides detailed procedures to follow in making the plan by the local planners. More fundamentally, many experts on the regional planning will be demanded in the near future. Some compound model which links, for instance, the forestry, the livestock sector, and the crop sector, needs to be devised. Finally, it is argued here that more elaborated model will work as an integrated environmental improvement plan which embraces living environment as well as agricultural environment.vironment.

It is the purpose of the this study to use preliminary data to improve job environment, after looking job satisfaction and environment of interior construction workers. The following were the method of study. First, Through the literature, concept and the main theory on job satisfaction are examined. And It draws elements affecting job environment and satisfaction of interior construction workers. Based on this, we analyze job environment and satisfaction, and find what the satisfaction level is low, after a survey of interior construction workers. According to the survey, the result of the job environment is poor that people are working a lot more than a standard 10-hour day, not paid for it and absence of the education system for future. The larger workplace was in poor job conditions. the result of the job satisfaction is higher in case of smaller workplace or workers with less than 1 year or more than 8 year. As job satisfaction for interior construction score 3.30, it showed relatively higher satisfaction than job environment and satisfaction elements.
