Accumulated epidemiological and animal studies have suggested that prolonged exposure to ambient particulate matter (PM) is associated with an increased risk of cardiovascular disease and pulmonary dysfunction. While diesel exhaust particles (DEP) contain large variety of compounds, polycyclic aromatic hydrocarbons (PAHs) are a dominant component contaminated in DEP. This article reviews effects of two PAH quinones, 9,10-phenanthraquinone (9,10-PQ) and l,2-naphthoquinone (l,2-NQ), on vascular and respiratory systems.

It has been a common misconception that landscape architecture is a gardening, landscape gardening or planting. However, landscape architecture is entirely different from gardening, landscape gardening and planting when it comes to professional category. Landscape architecture is a interdisciplinary science to improve a quality of citizen's life through analysing social culture, psychological configuration, aesthetic characteristic and integrating them in human society. Today's landscape architecture is a interdisciplinary technology including ecological and artistic value to create most of outdoor space used by human through preserving nature and enhancing the environment. The field has been changed constantly in the flow of the period and social development as providing green network system, recreation area, ecological environment in the city.

This study was conducted to investigate how much influence home environment and satisfaction degree with a undergraduate major have on female students' college adjustment. For this purpose, 190 undergraduate females participated in and completed all measures, and we analysed the data with SPSS computer programs. The results of this study are as follows: First, home environment and college adjustment have a positive correlation. Also, the students' satisfaction degree with their majors and college adjustment are positively correlated. Second, their satisfaction degree with a major was found to be different according to what year they are in. Third, the students' college adjustment was found to be different according to the satisfaction degree with their majors. Fourth, the female undergraduates' college adjustment was found to be different according to their home environment.

The purpose of the present study was to examine the factors on child care teachers' burnout. For this purpose, degrees of child care teachers' overall burnout, job satisfaction, and job environments were examined. Also, child care teachers' burnout was examined depending on their personal factors, job satisfaction, and job environment. Finally, the relative power of the three factors were examined. A survey was administered to 184 child care teachers in Seoul and Kyonggi areas to investigate their degrees of burnout, job satisfaction, and job environment. Maslach Burnout Inventory(Maslach and Jackson, 1986) and questionnaires on job satisfaction and job environmen were used. Data were analyzed with descriptive statistics and multiple regression using SPSS+12 version. Major findings are as follows: Child care teacher's overall degrees of burnout is not so high and different on their personal factors such as age, educational level, and career, and job satisfaction and job environment. The most powerful factor on their burnout was their demographic factors.

Human Factors Engineering (HFE) for Main Control Room (MCR) of Nuclear Power Plant (NPP) has been applied to optimize the design and operation of Man-Machine Interface (MMI) between operators and their equipment in consideration of physical, psychological and cognitive aspects. However, it has been observed that operators complain about environmental discomfort in the MCR since the operators in the MCR experience excessive stress due to the environmental factors such as inappropriate interior and lighting system. Since the HFE is an essential factor for the high fidelity performance of operators in the MCR, the adequate MCR environment design with HFE rules and guidelines is as much important to enhance the operability and reliability of the MCRs. Therefore, there has been a strong need to design a pleasant environment for the MCR to improve human performance of the operators.

This study was a preliminary investigation into improving the environmental and healthy quality of childcare centers. The purpose of this study was to determine the management condition on indoor environment and hygiene of childcare centers in Cheongju. Questionnaire survey was carried out from 11st to 26th of August 2004 by mail. Respondents were consisting of 55 teachers, an executive of each childcare center in Cheongju. From the survey results, there were some problems in 'empty period after remodeling work for preventing sick house syndrome', 'humidity controling', 'glare controling', 'indoor or outdoor noise controling', 'cleaning frequency of each room', 'washing method of toys', 'laundry frequency of rag doll and bedclothes'. So, we need to establish the regulations or give some educations and informations about indoor environment and hygiene to administrators of childcare centers.

Recently, the environment problems are risen to social problems. People have requested the convenience of a human activity and the enhancement of a human quality. The facility was, however, emphasized on the acquisition and treatment of water with the construction and maintenance of a irrigation and drainage structure. The concept of an environmental friendship has been introduced to change our society structure to an environment friendship at 21th century. But the concept lacks theoretical and systematic foundation. So, The maintenance technique, concrete products and construction methods will be made to be an environment friendship. The standards for environment friendship will be presented.

The ability to recognize human emotion is one of the hallmarks of human-robot interaction. Hence this paper describes the realization of emotion recognition. For emotion recognition from voice, we propose a new feature called frequency range of meaningful signal. With this feature, we reached average recognition rate of 76% in speaker-dependent. From the experimental results, we confirm the usefulness of the proposed feature. We also define the noise environment and conduct the noise-environment test. In contrast to other features, the proposed feature is robust in a noise-environment.

The modem world has brought a wave of changes, not the least of which is globalization or what is often referred to as the "borderless society." In recent times, changes in the global business environment, such as trade deregulation and advances in technology, are challenging us to find new ways of thinking about and coping with these new forces. The field of global logistics has encountered a host of paradigm shifts as well. Therefore, it is critical that managers involved in international logistics take into account perceptional swift or at least understand the value of fully utilizing information. The appropriate management of human resources is a key factor in dealing with not only new information technology, but also shifts in the business environment. In particular, it will be important for Korea's logistics managers at international logistics companies to continually work to develop themselves, as they must carry out a critical role in global supply chain management. If they fail to take heed of the demand's of the new environment, the competitiveness of Korean enterprises in international logistics will suffer severely.
