2. Special structures for coherent FBG group and fiber MZI sensors are designed. For weak signals or strongly interferenced signals, winding method, flat layout method, special coated fiber method or spring separation method, solid separation method are proposed, and the recognition ability for object signals is improved. The physical features of the object signals are extracted from various aspects by the parameters analysis such as maximum amplitude, RMS, ringing count, pulse count, event count and duration, by the waveform transform analysis such as Fourier analysis, AR spectrum analysis and joint-time-frequency analysis, and by statistic analysis of the parameters analysis results or waveform transform analysis results. And the features of different object signals are extracted when the optical fiber sensing systems are applied for railway location, axel counter, fence destruction monitoring and pipe destruction monitoring. Auto-recognition of the railway location signals with coherent FBG sensing system is realized by a linear discrimination function based on Fisher criterion. And auto-recognition of the fence destruction signals with a MZI sensing system demodulated by a 3×3 coupler is realized by a LMBP neural network.

15. The quality of interior environment in nursing home residents will become one of the attention-getting subjects due to the gradual increase of aging populations This paper directs at the research of nursing home`s interior environment factors in Tainan We use the standard of international practice to analyze the intrinsical data of environmental monitoring and establish the characteristics which from environmental physical reaction of nursing home The research items are air environments (PM10 CO CO2 formaldehyde TVOC) temperate environments and light environment (illumination average brightness daylight factor) etc There are the inductive conclusions of this research: 1 In basic medicine the clinical diagnosis means the theory and technique about physical examination with patients The definition of clinical diagnosis in architecture should be the diagnosis of building preserve and improve the feasible way to extend building`s service life and assure the residents of the healthy quality of interior environment The object of clinical diagnosis in architecture is not only to ensure the use of structure and environment quality but also keep the structure and environment quality in sustainable; therefore creating an efficient system of preserving plan is needed 2 It is an accurate and technical circumstance which about improving remedying and reconstructing the problems of structure space This circumstance includes finding questions ensuring causation ascertaining ultimate strength evaluating environment quality estimating the necessary of restoration and implementing on a suitable way Furthermore when reconstructing and ameliorating the appearance of structure space it should be respected and the memories of it should be preserved 3 In clinical diagnosis of environment quality of space the question of physical environment and the deficiencies of structure must be separated The structure space of construction and the high quality of space should be inspected strictly then observed the crucial reason that can find out any invisible and hidden causes The diagnosis of construction is to observe the reason of destroyed structure The environmental diagnosis of indoor and outdoor is to find out the crucial reason that influences health 4 In order to decrease the iterant problems the construction and environment of space should be diagnosed However the destruction by natural strength and artificial using by human are important causes that can affect the service life of construction Searching the cause of disease just like curing the patient which includes inspection diagnosis cure and prevention We tested the thermal conductivity of siding material in this research and then found out the roof east vertical face and west vertical face have most radiant heat especially the construction of RC The characteristics of opaquely outer casing have relations with the thermal conductivity of wall to wiz the ability of heat insulation Therefore increasing the efficiency of heat insulation and decreasing the endoergic factor of insolation are very important to temperate environments
而随著国内老年人人口逐渐增加,逐渐迈向高龄化之同时,对於高龄者使用空间之室内环境品质相关议题之探讨,亦成为未来我们需加以关注之议题之一。主要为针对台南某安养中心室内环境因子进行检测调查工作,利用现场室内环境测定以取得有效的实测数据;再藉由汇整相关国际评估基准,并进行实测数据比对分析,建立老人安养中心对物理环境反应之特性。并以前期相关研究文献回顾与老人安养中心实测案例现场的实验,来了解不同空间物理环境特性之影响,并将结果回馈实际建筑及室内设计之用。调查工作项目包含:空气环境之PM10、CO、CO2、甲醛、TVOC;温热环境之室内温度、相对湿度、人体PMV、PPD;光环境之照度、均齐度、昼光率等因子调查。本研究结果可归纳以下几点结论:1 所谓临床诊断医学乃相对於基础医学而言,是指实际与病人接触的医疗及护理行为中牵涉到的理论和技术;而建筑的临床诊断的定义应为建筑本体与室内外诊断、维护及改善所有可行的方式来延长建筑物的寿命,并确保人与室内环境空间品质的健康。建筑临床诊断目的为确保结构体与环境品质能继续使用,而能维持所需要的效能及承受能力。一个有效的维护计画体系是必须建立的 2 在建筑空间之问题改善、治疗与修复执行中,是一个精确与技术性的事项,其中包含找出问题、确定原因、评估结构应力强度、评估环境品质、评估修复与改善必要性、选择及执行一个适当的过程。其改善与修复也必须尊重建筑空间原有色彩与形貌,并保留原有记忆及文化。3 在临床诊断中空间环境品质中,物理性环境问题与结构构件缺陷必须分别判断,诊断建筑空间之结构与空间舒适品质必须详细观察其症结性问题,才能发现任何隐藏及有潜伏性缺陷的原因。建筑本体诊断是观察出建筑本体之破坏原因,而是内外空间环境诊断目的在於的找出影响健康因素之症结性问题。4 建筑本体与空间环境之预防评估目的为降低与抑制问题的再发生。然而,自然力的破坏与人为使用因素皆是影响建筑生命期之主要因素,找出病源问题就如同医生对病人的处理,包含了侦查、诊断、治疗以及预防。5 本研究以外墙材料热传导率测试结果发现,屋面与东西向立面是承受辐射热最多的地方,尤以 RC 的建筑更甚,不透明部分的外壳能特性主要与壁体的热传透率即隔热能力有关,但是承受来自日射的吸热影响,因此增加隔热性能与降低日射吸热因子是对温热环境是非常重要的。
16. Philosophers in ancient China early realized that a semantic triangle composed of symbol, expositor, and object was not a perfect expression system: symbolic system whose perceptive and physical attributes break away from object can not completely denote the object per se. Some objects such as''Dao'', ''Xuan''etc, which signify ontology of object, are hard to be thoroughly denoted due to their universality and supra- temporality.
中国古代哲学家很早就认识到由符号、解释者、对象三者构成的语义三角并非个完满自足的表达体系;脱离了对象的感知属性和物理属性的符号系统并不能完全指示对象本身,''道''、''玄''等些表示事物本体的对象由于它们具有普遍性、超时性的特征而很难被完全指示。
