Fizeau interferometer is used for inspecting the lens surface profile accurately. This study is focused on the design and optical measuring techniques for large optical components, such as a reflection mirror for large area lithography or astronomical purpose. A tower type Fizeau interferometer is designed and set up in horizontally with a 45$^{\circ}$ fold mirror which makes easy to align the optical path of heavy interferometer system. To align the optical path, a five-axes stage for the interferometer is required. This study shows a method of the 45$^{\circ}$ fold mirror alignment by using a three-axis stage instead of adjusting the interferometer itself or measuring object. This system will be installed on the large optics polishing machine during the manufacturing process as an on-machine inspection system.

The etiology of vocal fold granuloma was identified : post-endotracheal intubation, vocal abuse, acid reflux and idiopathic. The identification of the cause or causal factor is important, since the treatment must be fundamental directed at them. Treatment have included voice therapy and antireflux measures. Surgical excision is considered in patients who do not respond to medical management. In this study, a case of vocal fold granuloma resolved who underwent injection of the affected vocal fold. Botulinum toxin type A is probably successful by decreasing the strength during adduction in the arytenoid region which, when very intense, would perpetuate the granuloma. Localized injection of this neurotoxin is promising both as an initial treatment and as an alternative treatment in patients who do not respond to standard therapy.

A robust center estimation tecnique of n-fold engineering parts is presented, which use self-organizing neural networks with generating and merging learning for training neural units. To estimate the center of the n-fold engineering parts using neural networks, the segmented boundaries of the interested part are approximated to strainght lines, and the temporal estimated centers by thecosine theorem which formed between the approximaged straight line and the reference point, , are indexed as (.sigma.-.theta.) parameteric vecstors. Then the entries of parametric vectors are fed into self-organizing nerual network. Finally, the center of the n-fold part is extracted by mean of generating and merging learning of the neurons. To accelerate the learning process, neural network uses an adaptive learning rate function to the merging process and a self-adjusting activation to generating process. Simulation results show that the centers of n-fold engineering parts are effectively estimated by proposed technique, though not knowing the error distribution of estimated centers and having less information of boundaries.

In this paper, we introduce the notion of an implicative vague filter in BE-algebras, and investigate some properties of them. Also we give conditions for a vague set to be an implicative vague filter, and we characterize implicative vague filters in BE-algebras. We define the notion of $n$-fold implicative vague filters in BE-algebras and we give characterizations of $n$-fold implicative vague filters and $n$-fold implicative BE-algebras.

Vagus nerve palsy caused by herpes virus infection is rare. Here, the author presents a 65-year-old woman with acute onset of right side otalgia and sore throat, followed by delayed vocal fold paralysis on the same side. Vesicles were also found on the posterior wall of ear canal but the tympanic membrane was not involved. Laryngoscopy revealed multiple ulcerative lesions on the pharyngeal and laryngeal mucosa exclusively on the right side. One month later, she noticed dyshonia which turned out right vocal fold paralysis. Skull base to upper chest CT did not reveal local lesion. Three months after finishing the acyclovir, her symptoms were almost gone and vocal fold movement has almost completely improved. Vagus nerve involvement of herpes infection should be considered as a differential diagnosis for patients with herpes zoster oticus with sore throat.

Among the patients presented with the chief complaint of voice change, the one with unilaterally injected vocal fold was occasionally found at the out patient clinic. The most patients had rarely improved in symptom with conservative treatment under the impression of chronic laryngitis. Some papers were reported that the injected vocal fold(s) is due to laryngeal tuberculosis hick is sometimes associated with pulmonary tuberculosis. We investigated six patients presented unilaterally injected vocal fold with videolaryngoscope and performed histopathologic confirm with laryngeal biopsy respectively. There were low cases of laryngeal tuberculosis, one case of squamous cell carcinoma and one case of chronic larngitis. Proper management was done according to the tissue diagnosis. Pretretment and posttreatment videolaryngoscopic findings as well as some literature review were done.

Two-level fractional factorial designs are widely used when many factors are considered. When two-level fractional factorial designs are used, some effects are confounded with each other. To break the confounding between effects, we can use fractional factorial designs, called fold-over designs, in which certain signs in the design generators are switched. In this paper, optimal fold-over designs with four-level quantitative and two-level factors are presented for (1) the initial designs without curvature effect and (2) those with curvature effect. Optimal fold-over design tables are provided for 8-run, 16-run, and 32-run experiments.

Modem society has been complicated and diverse, and then various paradigms coexist. We can see Postmodernism moving in the flows of modern architecture. Therefore looming large is the Fold architecture that can surmount the limit of design in Postmodernism and Deconstruction and suits to the modern culture as an architectural alternative. So I believe this research can make us perceive the streams of modern interior space by considering the features and meanings of Fold conception which has been noticeable in the overall architecture and culture since the middle of 1990's with analyzing and defining atypical organic Fold characteristics appearing in modern interior since 2000, and also predict the next changing direction.

An 18-month-old, Scottish Fold with severe lameness and pain in the fore- and hind-limbs was diagnosed as Scottish Fold osteochondrodysplasia based on radiography showing mis-shapened phalanges, bone formation around the tarsal and metatarsal joints, joint space narrowing, and ankylosis. Although computed tomography (CT) is not considered a primary method for examining Scottish Fold osteochondrodysplasia, CT was undertaken in this case to investigate the cause of pain and reluctant ambulation in the forelimbs. CT showed immaturely ossified bone proliferation in the carpal bones. CT-based multiplanar reconstruction can reveal the anatomic relationship between the bone lesion and the joint in various directions.
