A autonomous vehicle requires improved and robust perception systems than conventional perception systems of intelligent vehicles. In particular, single sensor based perception systems have been widely studied by using cameras and laser radar sensors which are the most representative sensors for perception by providing object information such as distance information and object features. The distance information of the laser radar sensor is used for road environment perception of road structures, vehicles, and pedestrians. The image information of the camera is used for visual recognition such as lanes, crosswalks, and traffic signs. However, single sensor based perception systems suffer from false positives and true negatives which are caused by sensor limitations and road environments. Accordingly, information fusion systems are essentially required to ensure the robustness and stability of perception systems in harsh environments. This paper describes a perception system for autonomous vehicles, which performs information fusion to recognize road environments. Particularly, vision and laser radar sensors are fused together to detect lanes, crosswalks, and obstacles. The proposed perception system was validated on various roads and environmental conditions with an autonomous vehicle.

This paper is studied on the concept of environmental cognition on accordance with the oriental(especially Buddhism) process of thinking. The Yeongiron(theroy : one of th most famous philosophy of Buddhism, the theory of cause and occasion) consists of the upgam-yeongi, the aroeyasik-yeongi, the chinyeo-yeongi and the pupkye-yeongi. And the concept of these theory are as follows: The conceptural elements of upgam-yeongi consist of sack(色), soo(受), sand(想), hand(行), sik(識). The elements connects with the western environmental psychology such as sack and objects, soo and stimuli, sand and perception, hand and cognition, sik and behavior. Similarly, aroeyasik-yeongi that consist of sangbun(相分), kyunbun(見分), chajungbun(自證分), chungjajungbun(證自證分) connects with objects, perception, cognition, behavior too. The chinyeo-yeongi divide into smase(三細) and yukchu(육추), the samse consist of mumyungupsang(無 明業相), nungyunsand(能見相), kyungyesand(境界相) and the yukchu consist of chisang(智相), sangsoksang(相續相), chipchisang(執取相), kyemyungjasang(計明字相), kiupsang(起業相), upgyegosang(業繫苦相). These elements are relates with the concept of western environmental psychology from objects to behavior too. Pupkye-yeongi represent a characteristic of objects itself rather than a process of environmental cognition. However this study has limitations that the religion and scientific methods should be compare. sack(色) : an elements of it's derivation, all kinds of material soo(受) : a function of reception, feeling sang(想) : a representation of a thought in the mind hang(行) : mental operation sik(識) : a function of judgement sangbun(相分) : the thing in itself kyunbun(見分) : a reflection in the mind chajungbun(自證分) : confirmation of kyunbun chungjajungbyn(證自證分) : self-consciousness through self-examination mumyungupsang(無明業相) : a state of mixture with the object and the subject nungyunsang(能見相) : an operation of the subject kyungyesang(境界相) : a formation of object chisang(智相) : the beginning of distinction sangsoksang(相續相) : a judgement chipchisang(執取相) : a rsponse kiupsang(起業相) : have a influence to the next behavior upgyegosang(業界苦相) : retribution

The number of old buildings older than 30 years in Korea continues to increase from 29.9% in 2005 to 38.8% in 2020. Considering the growing urban regeneration projects, urban maintenance projects, the suppression of urban expansion, and the lack of idle land in the city, the dismantling of old buildings is expected to increase further in the future. As major accidents at building dismantling sites continue to occur, related agencies are also strengthening safety management of building dismantling works. While physical safety management such as collapse and fall is strengthened, there is a relative lack of interest in the health of workers at dismantling sites due to environmental hazards. Since relevant laws stipulate that construction waste should be separated and discharged, old buildings need to be considered for environmental hazards such as fine dust, floating bacteria, and floating molds when dismantling. In this study, we intend to find important safety management elements in the management of building dismantling sites, measure environmental factors harmful to dismantling workers, and present basic data for the management of dismantling sites in the future. "Safety management" was the highest priority, followed by "dust," "vibration," "noise," "bacteria," and "smell." The perception of the importance of "physical damage prevention" with workers working on dismantling and managers managing the site came out similar, but the perception of "work efficiency" and "health disorder prevention" through environmental hazard management showed different priorities. In the process of dismantling, floating bacteria and floating mold were collected, cultured, and measured the concentration in the indoor air. The measurement was measured by dividing it into pre-dismantling and during dismantling.

In order for school library to fully serve as a key educational element of a school, teachers' positive perception on the library's role is essential. Due to the lack of the perception, however, school libraries are not closely related to class activities in practice. Since teachers' perception on school library has been regarded as an given environmental factor in the field of school libraries, alternatives for revitalizing school libraries proposed in previous studies were not effective in practice. We developed a hypothesis that activities in school libraries have a certain impact on the teachers' perception, and tested the hypothesis and identified library factors to the perception in this study. Through a series of statistical analyses with the data from a questionnaire survey with teachers in elementary schools, we identified that the teachers perceived the library as non-curricular element, their perceptions were affected by the library. Consequently, the school library can influence the teachers' perveption. This study has implications to explore practical alternatives to improve the teachers' perception on school libraries by activities in school libraries.

The purpose of this study was to estimate the relationships between dietary factors and the stress perception levels of College students. A survey was conducted in June, 2010, targeting 332 college students in Gwangju. General environmental factors, stress perception levels, dietary behaviors, and dietary action guide performance of the subjects were evaluated by questionnaire, and food intakes was determined by the 24-hour recall method. The results are summarized as follows.: The score of frequency experiencing was $45.1{\pm}16.9$ for male students, and $47.0{\pm}16.7$ for female students. The importance scores were $50.8{\pm}18.5$ for males, and $53.3{\pm}18.7$ for females. The total score for dietary action guide performance was $39.6{\pm}7.2$ for males and $40.6{\pm}6.5$ for females. Nutrient intake levels were evaluated based on dietary reference intake (DRI), revealing energy intakes to be 68.5% EER in males and 73.9% in females. The mean intakes of nutrient were 54.2% RI for calcium, 73.6% RI for riboflavin, and 51.2% RI for vitamin C but 203.6% AI for sodium, which indicates an imbalance in nutrient intake. Analysis of the correlations between stress perception levels and dietary factors, scholarship achievements, financial problems, future problems, value senses, and family relationships revealed significant correlations with general environment factors, dietary behaviors, Dietary action guide performance, and nutrient intakes (p<0.05). The higher the stress perception levels of the students, the higher the energy, coffee and alcohol intake, which predicts that appropriate stress control in college students will lead to better dietary habits. It is expected that the results above will be used as basic data for the development of proper nutrition education programs and stress control strategies.

The purpose of this study was conducted to determine the influence of perceptions of the campus environment and health perception on stress of nursing students. Data were collected from three nursing colleges from December 01 to December 30, 2016, and data were collected by 223 students using the SPSS/WIN 21.0 program. Result of this study, the general characteristics of differences in stress were age, experience of clinical practice, gender, type of housing, personality and eating habits type, and experience in using the school health center. Stress showed negative correlation between perceptions of the campus environment and health perception. Factors influencing stress were eating habits, gender, perceptions of the campus environment and health perception, and their explanatory power on stress was 23.1%. Therefore, to reduce the stress of nursing college students, various programs should be developed and operated to improve the perceptions of the campus environment and increase the perception of health.

In the West, of the body's five senses sight is considered the most important but Ocular-centralistic thinking contains many issues. Privileging the subject and inhibiting interaction with the other senses, Ocular-centrism limits the experience of the world to the visual area. However, experiences can be understood as 'touching' various forms and are related to touch. With the heightened interest in the multi-sensuous side of the body contrary to Ocular-centrism, the intervention of the body in the external space has become an important issue in modern landscape architecture. This study explores the possibility of the haptic perception system that causes the active experience of a subject. Haptic perception plays a catalytic role leading an active experience of the subject and the subject experiences a sense of place through such haptic perception. By revealing what was known through the sense of touch through the concurrency and interaction of the various senses, haptic perception draws active participation The haptic perception system has been studied in various fields but has not been studied in the field of landscape architecture. Thus, this study discusses the aspect of haptic perception limited to landscape architecture shown before modernism. In a discussion on haptic perception, the concept of haptic perception is clarified through previous study reviews and literature and the characteristics of haptic perception are derived. Then, the problems of the Ocular-centrism system and the need for haptic perception are discussed. In the historical development process of haptic perception, the change process of the scopic regime is examined chronologically and the ways in which Ocular-centralistic thinking and anti-Ocular-centralistic thinking have been projected on the architecture and landscape architecture of each age are studied via literature and cases studies. The impact of the scopic regime on the landscape architecture field in the historical change process is examined.

Environmental Impact Assessment(EIA) in Korea has been used to improve environmental conservation and decision-making. Since environmental impact statement(EIS) was introduced in 1981 with the promulgation of the Environmental Preservation Act in 1977, which replaced the Pollution Control Act legislated in 1963. With a rapid growth of environmental perception as well as the diversification of development activities, however, it has recently bring about a strong demand for a new assessment process related to the strategic level of policies, plan, programs. Method of this study includes analyses of the situation of local EIA and its problematic issues through survey and analysis of information and data, analysis of the level of environmental awareness of professionals and case studies including analysis of foreign strategic environmental assessment. Accordingly, I have elicited a concept of SEA. In addition, I have studied on costs of environmental assessment, and efficiency of internalization of HIA. The survey was carried between September and November 2003, and 177 professionals were asks to complete a questionnaire. As a result of questionnaire survey of environmental pundits, it revealed that 83.8% of participants were in favor of introduction of strategic assessment. This result demonstrated more or less higher approval rate than those of awareness survey done by the Ministry of Environment, i.e. 86.0% ayes, and 14.0% nays. 22.8% of participants agreed to the opinion; "For introduction of this system, earlier is better," 50% reported having an opinion such as, "Will introduce this system in an earliest possible time after correcting problems," 26.3% reported having an opinion such as, "Let's decide the time for introduction of this system after correcting problems first,' and 0.9% reported having an opinion, "it's too early to introduce this system." Specifically, the ratio of ayes on introduction of the system marked 72.8%, and it revealed that a majority of respondents have an opinion such as, "Will introduce this system in an earliest possible time after correcting problems." As means of solutions for the problem regarding the limits of applications that existed in SEA System, factors, such as collecting a wide variety of opinions, securing experts, and faithful implementation, etc. were reported important, and in addition to these factors, respondents revealed having opinions such as, consistent research and development, reflection of public interest, establishment of professional organization, enforcement of after-management service, expanding investments in large, systemizing reference materials, and encouraging public participation, etc. To improve problems involving with present EIA system, it has been identified through this study that SEA is efficient and useful. In order to have SEA introduced successfully, it has been cleared that internalization of effectiveness of environmental cost together with HIA must be accomplished.
