  • Current research trends of non-copper wood preservatives for enhancing durability was reviewed; as a follow-up of the review in 2012 on copper-based wood preservatives. Main environmental friendly non-copper wood preservatives studied by many scientists were boron-based compounds, synthetic compounds from natural products, and pyrethroids family of chemicals, etc. The critical issue regarding treated woods with boron-based compounds used outdoors was the leaching of boron. Many studies mainly focused on boron fixation improvement using variety of polymers. Moreover, the studies showed notable increases in attempts to use natural products used commonly in the medical fields as wood preservatives as well as outdoor use of chemical modified such as acetylated wood developed in purpose of stabilizing dimension.

  • Sealants are an important element of modern architecture and serve as a building protection against weathering by providing barriers against ingress of moisture, air, and other materials. Exposure to a variety of environments often reduces lifespan due to changes in physical, chemical and mechanical characteristics, and UV, humidity, and temperature expansion are important issues that are directly related to durability. In this study, a combined deterioration test chamber was developed to simulate the environment of the open air as an instrument for verifying the durability of structural sealing materials indoors. In order to replicate special weather conditions, such as yellow dust, acid rain, and contamination by microorganisms, it was deemed impossible to replicate the outdoor environment by 100 %, and the results of the results of the results of the external exposure test of the structural sealant and the combined deterioration testing device. As a result of the displacement test of the outdoor exposure test, it was determined that the sealant was breaking apart and that it would be smooth, and the displacement would be up to three times greater than the initial material value of 1 year. The displacement test results of the combined deterioration test device show the tendency to deteriorate, decreasing the elasticity and tensile characteristics. In the case of denatured silicon, the current 400 cycles have been completed to confirm 12 months of degradation of the external exposure. The deformation of the test specimen cannot be verified with the naked eye, so it is considered that the conditions of the specimen are more stable than the silicon sealant. As a result of the outdoor exposure test, if the combined deterioration test device is structured and proposed in the relevant guidance or specification, the anticipated lifespan of 12 months in the actual use environment can be verified indoors and below 3 months later, economically.

  • Advertising is a communication that aims to persuade you through communication. Local governments are enforcing a lot of budget for outdoor advertisements and exposing advertisements to various media. However, in the case of outdoor advertisements, advertisements are executed without considering the specificity of the exposure environment, so it is inferior to the budget input. Therefore, this study aims to help local advertisement agents, producers, and related parties by classifying components by combining video analysis methodology and video ad analysis methodology for effective message delivery and immersion in local outdoor advertising. As a discussion to provide an efficient production methodology for outdoor advertising video production in the future, it is an extension of exploratory research through content analysis.

At first, the design principles of outdoor space for the mentally ill have been collected from the literature survey. Secondary, outdoor design requirements for the care program in nursing homes have been explored. Thirdly, good design elements have been collected from 6 nursing homes which have good outdoor space. Finally, Basic design principles of outdoor space of nursing homes in which older people with dementia live have been proposed by analysis and synthesis on the three stages before. As a result of this study, 6 dimensions in architectural planning of outdoor space for nursing homes have been presented : safety environment, various sensual stimulation, social interactions, support physical ability, accessibility, meditation.

  • Considering the present outdoor environment of city landscapes, the improvement of well-formed street landscapes is very important issue in Korea. At this point of time, it is very meaningful to understand the outdoor advertising design and the planning condition of buildings and examine various problems about this and the possibilities for improvement. Thus the purpose of this study is to accumulate basic data to establish design guideline and visual factors for the outdoor advertising for useful environment. The conclusions of this study are as follows: outdoor advertising design is powerful design tools as identified to city landscape. Planning factors for outdoor advertising design should be developed systematically and more fit to the street environment and designers in the aspect of control and guidance.

  • The purpose of this study is to evaluate the outdoor environmental quality level at the improvement areas of residence and examine the changes of these areas where the improvement process has been performed. The indicators of outdoor space were examined for case study and several improvement areas were selected and analyzed in terms of these indicators. The improvement areas may be divided into two branch, one is a housing improvement area and the other is a multi-family housing area. The results of this study were as follows; 1) Land-use intensity in both cases was much higher than before. 2) Open space ratio in the housing improvement areas was not enough but in the multi-family housing areas was enough. 3) The road ratio in both cases was much higher. 4) Parking space was not enough to accomodate all the cars in projects. 5) Public facilities and green space did not exist in housing improvement areas but existed a little in multi-family housing areas. In order to improve the environmental quality level, the proper residential density such as dwelling density, open space ratio, land-use intensity should be planned in advance.

  • Deterioration of the outdoor thermal environment in urban areas has become worse and worse due to the urbanization and overpopulation, etc. Most of existing researches about thermal environment are focused on the indoor environment in which the radiation heat exchange is relatively constant. However, the outdoor thermal environment is changed with time passages, because the thermal environment is highly effected by solar radiation. Thus, to simulate the outdoor thermal environment with accuracy, the solar radiation calculation should be considered, and the radiation heat exchange between building surface and ground surface should be calculated. The purpose of this study is to develop the simulator that can be possible to evaluate the outdoor thermal environment and pedestrian thermal comfort. In this paper, a new method which is coupled with convective heat transfer simulation and radiative heat transfer simulation will be proposed. And the coupled simulation method will be described through case study for outdoor thermal environment. From the results of simulation, the coupled simulation proposed in this study can assess the outdoor thermal environment with accuracy.

  • The purpose of the study is to analyze the planning characteristics of outdoor space in apartment complexes in terms of child-care environment. We selected 8 apartment complexes in Cheongju, within three years from construction, of small and medium-sized apartments ($60-85m^2$) where a large number of families with young children are presumed to reside in. As a result of the study, it was found that whereas the factors that can be quantified such as the floor height differences, the angles of ramps, and the number of the rest facilities are excellent, the qualitative part which cannot be easily quantified such as the location and direction of the rest facility and play materials should be improved a lot. And the following improvements were suggested; separating the pedestrian passage from the vehicle road in the main entrance of the complex, utilizing the piloti for infant caring, making the entrance area of apartment safe for pedestrians from vehicles, reallocating resting spaces, redesigning resting spaces safer to infants, building or reallocating existing booths at the stops of kindergarten buses, redesigning the square safer from vehicles with shades, making it possible for guardians to watch infants in playing field from the resting space, allocating natural environments essential for child development.
