碩士 === 國立臺北科技大學 === 建築與都市設計研究所 === 102 === With economic development and mass migration, the government has built a lot of apartments with no more than 5 layers from 1954 to 1984 to meat people’s demand for residential space. As time flies and residential structures depreciate, the function of systems decreases and forms an imbalance between its load and supply capacity; what’s more, owing to the high living standard and development of high-tech products nowadays, our life becomes more convenient and comfortable greatly based on electrical appliances. Therefore, improper indoor electrical wiring design, electrical defects and poor maintenance of electrical equipment cause degraded system function. In addition, people’s incorrect habits of using and inspecting the electric quantity of equipments as well as poor awareness of regular maintenance and inspection generally result in fire disasters. According to the statistics by the National Fire Agency, MOI, the most serious fire disasters from 1988 to June, 2010 were caused by electrical fire. It also shows that electromagnetic waves may be generated, spread and received when we use electrical appliances, and some medical researches testify that electromagnetic waves cause severe damages to the human body. People spend about 80% of the day staying and working indoors, which increases the need for electrical equipment, and this is closely related to the electrical load balance and damage degree of electromagnetic waves. Therefore, to create a convenient, comfortable, safe and healthy home life, the research attempts to establish the weights order for the hazard assessment of electrical fire disasters and electromagnetic wave in residences to the human body. It collects and analyzes documents related to the subject to design evaluation factors preliminarily, and formulates expert questionnaire by fuzzy De Phill method and conducts analysis of quality and quantity. The effective value of its De Phill credibility questionnaire reaches 100% and reliability is 0.792, both highly over the standard values. It further conducts the analytic hierarchy process to carry out the survey questionnaire on positive effect after determining the evaluation factors of fuzzy De Phill method, to obtain the overall weight and sequence of the analytic hierarchy process. The research results are as follows: experts believe that positive and practical actions should to be taken as the primary task to improve indoor wiring quality, in order to solve apartment electrical fire disasters and damage generation of electromagnetic waves, and preventative mechanism should also be established to regulate radio frequency (RF) and extremely low frequency (ELF) electromagnetic waves to avoid damage of electromagnetic waves. Besides, good shielding materials are also necessary to insulate and isolate contact with electromagnetic waves. It should start from improving indoor wiring quality work, and stress precautionary measures for electrical equipment like short circuit, electric leakage, overloading and consider the load capacity of the main line and power, etc. The correct concept of equipment operation and electrical appliance maintenance should be cultivated, and qualified staff employed for proper operation. According to the experts’ decision mentioned above, it is most important to improve indoor wiring quality and establish the management concept on electrical use and maintenance, highlight the implementation of legal norms and codes for radio frequency (RF) and extremely low frequency (ELF) electromagnetic codes, avoiding pollution of and a person’s exposure to radiation. Practical actions shall be listed in the top priority. Moreover, the load of the main line, the short circuit of the distribution line and stability of voltage should be considered in order to improve indoor wiring quality. importance of the implementation of legal norms , such as the development of radio frequency (RF) radio frequency and extremely low frequency (ELF) electromagnetic norms to avoid environmental pollution personnel radiation exposure . With particular emphasis on practical as that of improving the quality of indoor wiring should consider load , short circuit and voltage distribution lines stable trunk proceed .
