After passing through both agricultural and industrial phase, today society, due to technological revolution is becoming highly information oriented. This has resulted in the need for greater amounts of information in all fields of society. In step with this trend, office automation, home automation and factory automation are being promoted extensively. In turn these tendencies have been the main cause of grand scale disasters and the problem of ensuring safety in buildings has manifested itself as a problem for the whole society. However at present in most buildings the fire-fighting facilities and supervisory equipments are usually set-up separately, trailing greatly in areas of safety and efficency. Although there are numerous methods for improving security in office buildings, this study will focus on Intelligent Building and ultimately try to reach the goal of ensuring safety in buildings through interconnecting security systems with intellectualization of buildings. Untill now security systems were usually set-up and operated apart from the central supervision and control department which oversees and regulates the electricity, air conditioning, sanitary facilities and so on. But in Intelligent Buildings central supervisory, control system is introduced in which fire-fighting, crime prevention facilities, electricity, air conditioning, comunications devices and so on are all inter-connected organically, and thus each facility is comprehensively intergrated and interlocked. From the above viewpoint, planning of a system best suited to the requirements which have taken into consideration future usage and expansion on the basis of extensive professional knowledge and experience, must be the preconditions for the fulfillment of Intelligent Building with its highrate safety capabilities.

n order to evaluate the effects of therapeutic toothpastes containing monofluorophosphate, Vitamine-E, Flavonoid, Chlorhexidine, on the inhibition of dental plaque formation, the authors had examined the oral status of 50 students aged twentieth. Then they were given with cosmetic toothpaste and therapeutic toothpaste in due sequence. At the same time, all students were given with straight handled mixed bristled toothbrush and directed to brush teeth with toothpaste and toothbrush offered. The patient hygiene performance were examined in the 7th day, after that they changed their toothpaste to another one. So, each of them could use 2 toothpastes for 7 days respectively. On the other hand, to evaluate the reducing effects of dentifrice containing chlorhexidine on the numbers of Streptococcus mutans, 11 adults aged twentieth were experimented. They used offered toothbrush and chlorhexidine dentifrice and cosmetic dentifrice for 1 week and 3 weeks. To collect data, every volunteers rinsed their mouth with 0.1% pepton solution, the rinsing solutions were inoculated into MSBagar plate, After 3days anaerobic incubation under the conditions of 10% H₂, 10% Co₂, 80% N₂, The colony forms were identified by 9 biochemical tests. While, to evaluate the malodor reducing efficiency, the authors analysed the volatile sulfur compounds from the breath after ingestion of garlic powder, 10 adults aged twentieth were examined. To obtained adequate data, expirating breath was collected into sampling loop, after ingestion of garlic powder, the subject cleansed the oral cavity by one of the designated methods and reevaluated at 2, 7, 12 and 17minutes after ingestion of garlic powder. Gas chromatographic techic was employed for the evaluation of volatile sulfur compounds in mouth air. The percent change in VSC concentration of air samples were calculated in relation to values of it after ingestion of garlic powder immediately. Thereafter, the data was compared statistically and discussed. The obtained results were as follows; 1. Therapeutic toothpastes inhibited plaque formation more effectively than cosmetic toothpaste. 2. After the use of therapeutic toothpaste containing MVFC, the numbers of Streptococcus mutans were decreased both 1 week(P<0.0l) and 3weeks(P<0.05). 3. Therapeutic toothpaste containing MVFC reduced more methyl mercaptan and allyl mercaptan(P<0.05) than control cosmetic toothpaste.
