As the population of consumers of outdoor wear expands, there is increasing interest among consumers in trendy lifestyle outdoor. Accordingly, it is essential to develop designs that are drawn from outdoor wear. This can be limited to traditional mountaineering suits, and designs developed from men's outdoor zip-up T-shirts, which are highly utilized in everyday life, are very important. This study developed the design of a summer zip-up T-shirt for men with both functional and aesthetic qualities. Visual images of foreign brands and domestic outdoor-focused T-shirts from the spring/summer seasons of 2013-2019 were collected to analyze the following modeling elements: silhouettes, details, colors, materials, and prints. In addition, the design concept was derived by analyzing presentations from the global outdoor trade Fairs (2013-2019). To develop a sustainable eco-friendly outdoor summer T-shirt for men, the concept was derived according to three categories: eco-friendly, sportism-expressed active elements of sports, and an outro-concept of urban town wear as an outdoor lifestyle. Thus, a total of 12 styles of design were developed. High utilization of the outdoor wear T-shirts (which are also popular as lifestyle wear), is an important aspect of building a segmented lineup of the slow-growing outdoor wear market and supports expansion of the scope of theoretical research on outdoor wear design.

The trend emphasizes children-oriented, play-oriented ecological education programs for children's ecological education. And most of these nature -friendly and eco-friendly education takes place outdoors. Therefore, outdoor space planning is important in childcare facilities. This case study aims to analyze the actual conditions of outdoor spaces in daycare centers and to provide standard data for outdoor space planning. In order to provide basic data on the improvement direction and planning standards of outdoor spaces, this present study conducted the composition, utilization status and related problems of outdoor spaces for nature -friendly ecological education in childcare facilities. Accordingly, outdoor space planning for ecological education should consider outdoor space characteristics such as free and easy accessibility between indoor and outdoor spaces, openness of space, flexibility, dynamic/static space, and nature affinity. Therefore, for an ecological education environment, children should be able to freely approach nature and play in the natural environment without any restrictions and artificial controls. Also, in urban areas, natural environment such as parks and open spaces should be considered as outdoor play spaces for children.

This study was performed to investigate airborne formaldehyde concentration in preschool facilities. Arithmetic mean of indoor formaldehyde concentration in urban area was 34.9 ppb(Geometric mean 24.4 ppb) whereas outdoor concentration was 21.5 ppb(GM 11.9 ppb). In rural area, formaldehyde concentrations were 36.4 ppb(GM 28.7 ppb), 4.1 ppb(GM 4.1 ppb), respectively. There is no statistical significance between the formaldehyde concentrations of urban classrooms and those of rural area. We verified that the distribution of airborne formaldehyde concentration was log-normal characteristic using Shapiro and Wilk test. The 6.7% of urban indoor samples was exceeded the domestic standard limit of indoor air quality. From our study and other study, we concluded that the major emission sources of formaldehyde in preschool facilities was in indoor rather than outdoor.

The purpose of this study is to overcome the realistic pressure and the limit of school environmental education and to develop an environmental education program that can provide students, who live in an urban area, have difficulty in contacting with nature, with an opportunity to experience the nature in the school outdoor environment, which is their daily living space and is a ground of environmental education. First, I developed an analytical tool which can be used to determine the degree how the environmental education is related to the school outdoor environment with 8 categories(spaces). And I analyzed the 2007-79 curriculum of lower grade(1 and 2 grades) of the elementary school provided by the Ministry of Education and Human Resources Development by using the analytical tool and found out that this curriculum was suitable for the environmental education utilizing the school outdoor environment. According to this curriculum analysis, the studying subjects which could be suitable for the environmental education utilizing the school outdoor environment were extracted, and based on these subjects, an environmental education program was developed. The environmental education 'in' environment program were composed with 5 modules and 18 activity subjects suitable for students advancement phase, and these activities can be implemented with experiencing, understanding and expressing by using 5 senses. I also proposed a plan that can be used to apply this program continuously to the lower grades(1 and 2 grades) original experience activity class.

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.

Recently, rapid development of technique and change of lifestyle during nighttime has activated the urban outdoor lighting and renovated consideration of nightscape. As the interest of nightscape increases more widely, outdoor lighting has been installed more and more in the cities. Nightscape comes in diverse forms. So, there is no absolute standard for outdoor lighting. But only bright outdoor lighting is not necessarily a good nightscape. Installation lighting without master plan or excessive outdoor lighting may cause a inharmony. This study aims to analyze the luminous characteristics of facade in shopping complexes. For the purpose, four large-scale shopping complexes located in Dongdaemun area were selected. Building facade composition, outdoor lighting composition, and lighting equipment of each shopping complexes are surveyed, and luminance of building facade were measured with Prometric 1400. The result of the study are as follows; (1) Horizontally large-scale shopping complexes emphasize the building entrance and shape of the building at night by outdoor lighting. (2) Non cut-off luminaries installed in building entrance and shop front caused the potential of light pollution.

The purpose of this study is to evaluate the indoor air quality (IAQ) and energy benefits of a dedicated outdoor air system (DOAS) and compare them with a conventional variable air volume (VAV) system. The DOAS is a decoupled system that supplies only outdoor air, while reducing its consumption using an enthalpy wheel. The VAV system supplies air that is mixed outdoor and transferred indoor. The VAV has the issue of unbalanced ventilation in each room in multiple zones because it supplies mixing air. The DOAS does not have this problem because it supplies only outdoor air. That is, the DOAS is a 100% outdoor air system and the VAV is an air conditioning system. The transient simulations of carbon dioxide concentration and energy consumption were performed using a MATLAB program based on the thermal loads from the model predicted by the TRNSYS 18 program. The results indicated that when the air volume is large, such as in summer, the distribution of air is not appropriate in the VAV system. The DOAS however, supplies the outdoor air stably. Moreover, in terms of annual primary energy consumption, the DOAS consumed approximately 40% less energy than the VAV system.
