Chinese hotel industry needs to continue consummation. Especially the physical environment direct or the indirect influence to the consumers has not caused the hotel managers enough attention. Chinese hotel industry also lacks to the physical environment whole perception and the understanding. This paper research purposes are: how through that improve the hotel physical hotels. And what's disparities between the Chinese hotel industry in the physical environment and the Western developed country, how needs to improve and so on. Therefore, this paper has mainly studied and analysis the hotel atmosphere, the hotel facility, the hotel cleanliness, the hotel position, customers' overall satisfaction, the repatronage which independent effect, relations and the importance of them in Chinese hotel industry. This paper have made 5 hypotheses to relations of the hotel atmosphere, the hotel facility, the hotel cleanliness, the hotel position and customer's overall satisfaction, the repatronage. We have carried on the questionnaire survey to four hotels, altogether send out to the 250 questionnaires, and have received 202 questionnaires. Through after these analyses, the 1 hypothesis cannot have the data support. Therefore, the conclusions are: the first, the good hotel atmosphere has the positive influence to the consumer overall perception; the second, the higher hotel cleanliness has the positive influence to the consumer overall perception; the third, the convenience hotel position has the positive influence to consumer's perception; the fourth, the consumers' higher overall satisfaction has the positive influence to consumer's repatronage. But the influence of the higher hotel facility to consumers' perception cannot have the enough support from the data.

This study examined the effect of the perception of age-friendly environment on perceived social bonding. In particular, this study focused on the mediating effects of perception of age-integration between perception of age-friendly environment and perceived social bonding. The data were analyzed using the '2017 Ages Integration Survey' conducted by the Korea Research Foundation(SSK). A total of 997 adults from 20 to 86 ears of age were participated in this study. The perception of age-friendly environment was measured using the age-friendly city guidelines set out by WHO and perception of age-integration was measured using questions that asked about age flexibility and age diversity. Also, the social capital scale was used to measure perception of social bonding. In order to increase the reliability of the analysis results, age, gender, educational achievement and residential area were controlled. Structural Equation Modeling approach was employed to answer the research questions. The results are following. First, perception of age-friendly environment was significantly associated with perceived social bonding in a positive direction, controlling for age, gender, educational achievement and residential area. Second, perception of age-integration partially mediated the relationship between perception age-friendly environment and perceived social bonding controlling for covariates. Based on these findings, this study proposes political and practical intervention strategies to promote age-friendly environment and age-integration.

The purpose of this study was to investigate the relation between perception of family environment and mental health of boy's high school students. In order to obtain the appropriate data, a questionnaire was administered to 240 boy's high school 2nd-grade students in Pohang city from March 19 to March 28, 1992. The instruments used for this study were Moos's Family Environment Scale Form R and Kim's Symptom Check List-90. The conclusions were as follows : The level of perception of family environment was lower than mean score. Cohesion, achievement orientation, independence, organization, expressiveness were percepted high but active-recreational orientation, intellectual-cultural orientation were percepted low. Mental health of most respondents was well. The scores of obsessive-compulsive reaction and interpersonal sensitivity were high, the scores of somatization and phobia were low. General characteristic variables significantly related to the level of perception about family environment were father's occupation and mother's education level. There were no significant differences between general characteristic variables and mental health. There were mostly negative correlations between perception of family environment and mental health. Cohesion, expressiveness, independence, intellectual-cultural orientation, active-recerational orientation, moral-religious emphasis, organization were negatively correlated but conflict, achivement orientation, control were positively correlated. Cohesion, expressiveness, conflict, achivement orientation, active-recretional orientation, organization, control were significantly related, but independence intellectual-cultural orientation, moral-religious emphasis were no significant correlation.

Environment perception and three-dimensional (3D) reconstruction tasks are used to provide unmanned ground vehicle (UGV) with driving awareness interfaces. The speed of obstacle segmentation and surrounding terrain reconstruction crucially influences decision making in UGVs. To increase the processing speed of environment information analysis, we develop a CPU-GPU hybrid system of automatic environment perception and 3D terrain reconstruction based on the integration of multiple sensors. The system consists of three functional modules, namely, multi-sensor data collection and pre-processing, environment perception, and 3D reconstruction. To integrate individual datasets collected from different sensors, the pre-processing function registers the sensed LiDAR (light detection and ranging) point clouds, video sequences, and motion information into a global terrain model after filtering redundant and noise data according to the redundancy removal principle. In the environment perception module, the registered discrete points are clustered into ground surface and individual objects by using a ground segmentation method and a connected component labeling algorithm. The estimated ground surface and non-ground objects indicate the terrain to be traversed and obstacles in the environment, thus creating driving awareness. The 3D reconstruction module calibrates the projection matrix between the mounted LiDAR and cameras to map the local point clouds onto the captured video images. Texture meshes and color particle models are used to reconstruct the ground surface and objects of the 3D terrain model, respectively. To accelerate the proposed system, we apply the GPU parallel computation method to implement the applied computer graphics and image processing algorithms in parallel.

This study suggests the optimum interior environment by projecting the criteria to design the living space light-ing that select the lighting environment among the sever-al environmental factors that influenced on the human perception. As a correspondance between the visual perception and the lighting, visual perception process, vision system, and visual perception system are investigated to compre-hend the lighting, and then conceptual contour of the lighting environments are presented which are transmit-ted the visual informations. As a lighting factors which are influenced on the visu-al perception, light source color is analized. Foundationally, the effect of the lighting methods and the techniques are investigated, and the changes of the lighting methods which influences on the space perception are examined through the previous results. As the changing the light sources color, the changing the subjective feelings of space perception through the ex-periment. This study is concluded with the proposition of the ef-fective lighting and the importance of the lighting envi-ronment.

With the progress of the aging society into the aged society, the planning of senior housing is inevitably required. Among the factors of planning, color appeals to people's vision which mostly accepts information about the environment, so age-related color vision changes should be studied. The purpose of the study is to find out characteristics of color perception focused on yellow and blue with advancing of the yellowed eye sight in the old age. The findings are as follows. (1) Regardless of gender, losses of color perception in sensitivity is occurred as aging is proceeded. But the rate of reduction is mitigated compared with the ex-research in Japan because of the promotion of physical health. (2) Human lens coloration was not common until 85 years old and the hue of yellow and red was easily perceived by the older subjects. (3) Yellow is more preferred to other colors by the elderly and accuracy of yellow-color perception is higher than that of blue-color. (4) It is especially hard for the elderly to perceive the difference between pure blue and mixture of blue-green. Therefore blue and blue-green should not be adopted simultaneously in senior housing environment. Except for the space which specially requires carefulness, various color preferred by the elderly should be applied to the senior housing environment to satisfy their psychological condition and provide the vitality of life.

The purpose of this study is to investigate かe factors related to the environment-oriented consumer behavior, and to analyze the effects of environmental knowledge, perception of environmental problems, and environment-oriented attitude on the environment-oriented consumer behavior. The data used in this study were collected through questionnaires on 535 wives living in Cheju City. The data were analvzed by using SPSS WIN program. The summaries of this study are as follows. Using behaviors was influenced by age and family income, but buying and disposing behavior are not influenced by socio-economic variables of wives. Environmental knowledge only has effects on disposing behaviors, and environment-oriented attitude behavior has effects on buying, using, and disposing behavior. But the perception of environmental problems hasn't effects on them. Wives' environment-oriented behavior are more effected by environment-oriented attitude than perception of environmental problems. In buying behavior, environment-oriented attitude is the most influential factor, and the reference group is the second influential factor. But in disposing behavior, the reference group is the most influential factor, and environment-oriented attitude is かe second influential factor.
