Recently, many automotive companies tend to apply an air quality system (AQS), which prevents polluted air such as smoke or dust by controlling air intake actuator of vehicle, to satisfy the consumer's need for agreeable in-vehicle environment. However, performance of the traditional AQS is not satisfactory because a polluted air may enter into the inside of vehicle through the breaks of windows. Especially, the commercial vehicles such as bus or truck need to be prevented polluted air from the breaks of vehicle. Hence, as an alternative to the traditional AQS, this paper presents the architecture of smart AQS for commercial vehicle and implementation of the smart AQS. Also, the performance of the suggested system is evaluated through an experimental testbed.

Studies on the ways to construct agreeable sound-amenity have been processed in Korea recently and Virtual Acoustics Field Simulation System (VAFSS) which is an active acoustics reproducing system has been made as a technique to realize the results of the study. This system catches the changes of surroundings and produce sounds which go well with the mood of the space. The fact that a man thinks a sound goes well with factors of the environment should be an individual evaluation. Thus, the standards to classify factors influencing the preference of the sound, which can be judged by the environment, are needed. This study suggests the standards of factors to provide agreeable sound for people according to changes of the time and other elements. Among the factors influencing environment, the temperature, the humidity and the wind were suggested as standards of discomfort Index and wind chin temperature. Besides, only the intensity of illumination has been chosen to estimate the intensity of radiation as a part of factors of the whether.

The principle of Korean Traditional Housing was to be harmonized with the nature with shapes according to regional climate and materials easily available from the region. These environmentally friendly characteristics protected indoor environment from climate changes. The characteristics of Korean traditional housing to control indoor environment would be very useful for contemporary housing in that current issues, improving housing amenity and wellbeing, had basic goals same with what Korean Traditional Housing had. Though it could be found characteristics of indoor thermal environment heated by Ondol Heating System, analyses of evaluation made by occupants of the rooms were insufficient because most of the studies had been focused on the measurement of indoor thermal factors. Thus, with an evaluation of occupants for the indoor thermal comfort and an estimation of discomfort derived from the result of vertical temperature distribution, it was studied whether the agreeable indoor range of rooms, of which was Jeonju Hanok Living Experience Center, heated by Ondol Heating System corresponded to the agreeable indoor range presented in references.

The purpose of this study is to identify current condition of night lighting plan for the outdoor space in an apartment complex and to examine how residents perceive that environment. For this purpose, considerations and standards for safe and agreeable night lighting environment were examined through literature study. And a field study to determine the current state of the night lighting environment was conducted, and finally a survey was executed to find out residents' satisfaction, requirements and consciousness on that lighting environment of apartment complex. Findings of this study can be summarized as follows. Firstly, most standards for night lighting environment focus on the urban environment as a whole, so they have very few clear standards exclusive for the outdoor space of the apartment complex. Secondly, most of outdoor spaces surveyed in this study have met the basic illumination standard, but some spaces had parts where lights were off or out of order forming dark zones, and in some parts lights were screened by trees causing shades, poor safety and a narrowed sight. Thirdly, residents had interest in the night lighting environment of the outdoor space, but they were not fully satisfied with that environment. Fourthly, residents were negative about such factors of the environment as safety, convenience, recognition and aesthetics. These factors should be reflected in planning and improving the night lighting. It is expected that this study provides basic information necessary to plan safer and more agreeable night lighting, and to satisfy the residents' need for liveable apartment complex.

This research has measured the indoor environment of thirty hair salons, which are located on Gunsan-Si, Jeonlabbuk-Do, from April 1st to April 30th 2005, to examine the related factors on a work environment of hairdressers and a revelation of respiratory symptom, and has polled 260 hairdressers and 350 office workers. After measuring the physical environment of hair salons, the room temperature, the relative humidity and the illumination was in an agreeable range, and 60 percent of hair salons depended on the natural ventilation through the windows. The levels of acetone, toluene and xylene, which were measured at the hair salons, were all under the safety standards (p<0.05), but these are still harmful and volatile matters, so they can be bad for your health by the contact of skin and respiration. The harmful factors that affect a revelation of respiratory symptom were the group who has many exposures of permanent wave or bleaching/dyeing and not many experiences of hairdressing work, the group who smokes every day, and the group who never exercises at all (p<0.05). This result shows that there are possibilities of health problem for hairdressers from the constant and repeating hairdressing works with the exposure of chemicals such as the permanent, bleaching and dyeing. so that hairdressers recognize that they need appropriate ventilation facilities for their agreeable indoor-environments. And also, to prevent the direct exposure of chemicals as much as they can, they need to have an active management of an individual health care by wearing gloves, mask or something like that.

Recently there have been growing disputes between neighboring local governments over jurisdictional rights or property rights of ocean resources in Korean coastal waters. The reasons for the disputes come mainly from the increasing interests by local governments that begin to see the oceans as the source of resources and wealth. The maritime dispute is more complicated and sticky than the inland ones, and requires not only socio-economical but political approach, therefore sometimes demanding a plenty of time and endeavor. Also coastal states that have suffered from maritime boundary problems have different issues under the different environment and historical background. For Korea, as the maritime boundary issue has very recently soared to the surface, though it was latent for the period as long as 20 years, we have just taken steps toward an institutional approach on it, seemingly more to go to reach an agreeable resolutions to the disputes. This paper highlighted the issues surrounding the maritime boundary on the sea surrounding Korean peninsular after addressing the current situation of the boundary disputes. It will help explore and assess the possible solutions to the boundary conflicts over the lateral boundary between local governments.
