The purposes of this research are, first, to investigate the present condition of indoor thermal environment in winter. Second, to find out how residents' knowledge, consciousness, and behavior changed after provided with education and information of indoor climate. Finally, to reveal how this changes make alteration to their indoor environment. Thirty apartments were collected, and then divided into three groups as Control Group, Education Group, and Edu-information Group in order to conduct the purposes. Provided education and environmental information turn out to have a positive effect to residents' knowledge, consciousness, and behavior, and consequently, it leads residents to control their indoor environment more actively in some cases. Thus, it is important to provide residents with environmental education and information, and it should be conducted regularly in order to maximize the positive effect of education since it tends to decrease as time goes by.

I suggested the design learning environment based on affordance concept approach for supporting and improving learners' behavior and outcome for convergent design education in this study. The design learning space should be applied teaching and learning activity, especially learners' behavior, physical space condition to support the design thinking process. The design learning space needs openness, individuality and connectivity to support the learners' behavioral to immerse, participate, cooperate, understand, think and fulfill the design thinking process. The composition principles of the learning environment for convergent design education supports communication and collaboration among members for independence and interaction. The spaces for design research and teaching needs high privacy while facilitating visual communications through special materials and wall structure design. Also, for connectivity to improve the learners' physical and visual contact, the environment of the classrooms requires flexibility and mobility by providing an open space integrating unit cells for realizing learning purpose. These are provided by formed of an open structure for inducing visual communication and physical contact to involve the design activities and the mutual interchange.

A multi-server queueing system with an infinite buffer and impatient customers is analyzed. The system operates in the finite state Markovian random environment. The number of available servers, the parameters of the batch Markovian arrival process, the rate of customers' service, and the impatience intensity depend on the current state of the random environment and immediately change their values at the moments of jumps of the random environment. Dynamics of the system is described by the multi-dimensional asymptotically quasi-Toeplitz Markov chain. The ergodicity condition is derived. The main performance measures of the system are calculated. Numerical results are presented.

The purpose of this study is to examine the actual condition of environment conscious logistics(ECL) system which is essential to make material recycling economic society. ECL management which meant simply recycle is tend to promote material reduction, reuse and recycling. We have made case studies about advanced ECL system. To examine manufacture companies' ECL system, we made survey form which is consist of 82 questionnaires and 129 companies have participated for this. And we have analyzed the survey responses. As a result, we propose the way of constructing ECL system in Korea.

This research was performed to examine the ratio of blindness to the child care environment and compare the evaluation of it among principals, teachers and mothers. Data were collected from questionnaires completed by respondents of this research were 37 principals, 37 teachers and 261 mothers of infants and toddlers at child care centers in Incheon, Korea. Cross tabulation, one-way ANOVA and Duncan's Multiple Range Test were utilized to analyze the data. In almost all of the items about the child care environment, mothers showed higher degrees of blindness than principals and teachers. In most of the items, mothers'evaluations were higher than those of principals and teachers. As a result, the researchers recognize a pressing need far programs far parents to improve the quality of child care.

1. The objective of this paper is to investigate the indoor environment from the viewpoint of interaction between physical environment and the human responses. 2. A continuous measurement has been carried out for 1 year and distribution of variables have been measured for 1 day. 3. The attitude of workers was investigated by a questionnaire. 4. As the result, average luminance represented more than 800-1800 lx in the office, in contrast with less than 1000 lx in the encourage luminance of an office. 5. There was a significant difference of the occupants' response to the light environment between the neighboring environments. 6. Measured thermal conditions are on the edge of the ASHRAE comfort envelope in summer, and in the neighborhood of the lower dry limit of the envelope in spring.

The purposes of this study were to exploring the rural residents' satisfaction of living environment and social service. For these purpose we collected the data from the residents in rural area(1,000). The major findings of this study were as follows : First, the total satisfaction score is 58.9. The highest score group is housing and environment(69.9). And the lowest score group is cultural life and leisure environment. Various welfare services have been carried out for low income people, disabled people, old people, children and rural women within the social service system. But many respondents did not have chances to use social service because it was not efficiently provided many social services. So most of the residents in village wanted more welfare services. Second, the qualitative enhancement is more important than physical infrastructure expansion in order to improve rural settlement condition(housing quality, water supply and drainage, road and traffic system, medical care etc.)

The biodegradability test of bulking agents in feces composting process is conducted to increase the management efficiency for environment-friendly rural toilet developed by National Rural Resource Institute in 2001. In the case study through references and field study, ash, fallen leaves, and wood chips are commonly used in the ecological toilet. Extension officers and farmers prefer rice straw, fallen leaves, and chaff among the rural resources as a bulking agents in the aspect of getting and storage as the result of questionnaire survey. As the result of biodegradability test including the temperature change, $CO_2$ gas production, and C/N ratio change of composting pile under the condition of aerobic composting apparatus, rice straw and chaff are good bulking agents for environment-friendly rural toilet. It is recommended that easy getting materials among the above mentioned materials are used for bulking agents as the region and season in environment-friendly rural toilet.

Under the changed market condition, The objectives of this study are to develop and test a research model specifying the relationship between customer loyalty and sale of environment-friendly food in korea. The target population of this research is consumers in seoul and some major cities. they are judged to have bigger environment-friendly food buying power and represent the future environment-friendly food consumption trend in korea. Results acquired from statistical analysis can be summarized like the following. The label-related components were important factors effecting the satisfaction and the loyalty. Also this study indicate that the customer loyalty is positively related to producer, ingredient indication, advertisement, and negatively related to price.

Human exists in environment. As environment affects in human movement, human reacts to everything happens in environment especially by the view point of visual continuity and changeability. This study has two purposes. The one is to clarify the visual changeability due to the Human movement from the visual point based on checking the visual field. And the other is to understand the applicable possibility of Philip Thiel's method through the experiment in passing ways. Condition of this study is that colors and figures are affective elements of visual environmental sequence by the Human movement. The Human movement is due to the visual phenomenon. That means it is not limited in Philip Theil's method(Node, District). In particular, the chroma which is checked by the BPA(Basic-Pattern-Area) is the most affective visual environmental element in contemporary shopping mall. Also, everything in visual environment and the movement is connected by the time axis. As an analytical method, the sequence notation devised by Philip Thiel was applied.
