Though children are imperfect and immature in themselves, they have their own merits and characteristics, so that they should not be appreciated by the adult's own viewpoints. The needs of a child are obviously different from those of an adolescent or an adult. Therfore we should understand their mentality and psychology in order to give desirable outdoor space to them. In this study, children's view of outdoor environment was studied by analyzing the painting of object elementary school students of one and the other urbanizations and schooling years and different schooling years also. The data were drawn from 182 children of two different urbanization levels. The urbanization level was standardized with urban area(Taegu), and rural area(Jukjang - myon). According to the research, more area of garden was exprssed In paintings of urban children. House was expressed vy far more frequently in paintings of rural childrin than in those of urban dwellers. The children of urban expressed recreation facilities more frequently within their garden. It reflected the limitation of play space for them, As a result, the preference fur outdoor 7pare of children should by considered in Planning space for them.

최근 대기환경 악화로 송전용 철탑 도장의 열화가 촉진되어 내후성이 강한 신도료를 송전철탑에 적용이 필요하게 되었다. 도료 제조업체의 신도료로 도장시편을 제작하여 옥외에 폭로후 전문기관에서 성능을 확인하였으며, 이를 토대로 도료의 재질을 실리콘 아크릴우레탄계로 변경하였으며, 철탑용 도료 성능시험 기준을 강화하여 철탑 재도장에 따른 유지보수 비용 절감이 될 수 있도록 개선하였다.

In this paper, we described a design and implementation of a sensor node for environmental monitoring. The main focus of design for sensor nodes is to isolate MCU for treating sensors from the RF module for considering various communication environment. The second is to make the interface between MCU and varity of sensor. In addition, we choose a narrow band communication module, cc1020, for the admittance of Korea government communication law. We also use a uC/OS-II as an operating system which is famous for 8bit MCUs. We showed that the communication performance is sufficient to use the communication module in a out-door environment through several experiments in that it is possible to transmit between 100m distance through experiments in a mountain.

Outdoor lighting have been controlled by laws and regulations instituted in accordance with each country's situations because lights are also considered as one of pollutions at the view of environmental pollutions and energy saving. Thus, in this paper, we suggest the calculation method and regulations of light pollution suitable for domestic by comparing and analyzing various types of road lighting luminaires based on the calculation method of light pollution accepted internationally.

The primary concerns of recreation plan are to provide visitors with quality of recreational experience and to protect of recreation resources. The quality of recreational experience is often defined in terms of social carrying capacity. The carrying capacity is revealed as perceived crowding. In this respects, measuring perceived crowding is useful tool of social carrying capacity determination. This study is to test the structural equation model that includes variables affecting perceived crowding. Through an on-site questionnaire survey, 467 visitors on Naejangsan national park were collected. The results of the study are follows. The encounter level on facility area is higher evaluated as crowding factor than other area in the park. It can be concluded that visitor perceived crowding when facility area situates high density use level rather than other areas expose high density use level. In the path analysis, the input variables(attitude, experience, encounter level) on the structural equation model affect significantly on perceived crowding. Especially, the attitude on the park management polocy is the most affecting factor on perceived crowding.

As tourist and cultural city, Chungju city struggles to exploit the new tourism resources including lighting scenic spots. This study aims to analyze the present lighting situations and suggest the alternatives for improving outdoor lightings of Hoamji Park - one of the most famous landmark in Chungju city. For the purpose, field surveys and experiments were performed on selected settings. Illumination levels were measured to compare with the KS standard by using MINOLTA T-10 instruments and some findings were discussed. As a result, some alternatives to improve the park's night images including new lighting concept, lighting fixtures and installations were suggested.

In this paper, we were investigated leakage current properties of outdoor insulator on climatic environmental factor. Contamination is one of the most important factor to determine the performance of insulator. Thus, it is very important to exam the contamination degree on the outdoor insulator. There are many limits, such as reliability of data, interval of measurement and similarity of environmental conditions, in conventional method. So, we measured phase and leakage current of outdoor insulator using the temperature & humidity chamber. In this investigation, phase difference was measured to compare the variance of phase difference with the contamination degree and relative humidity.
