In spite of The exterior design of buildings has a remarkably significant value in terms of public aspect some exposed architectural equipments spoil the appearance of building. The design elements of exposed architectural equipments were partially changed and assessed in the semantic differential method. Thus the aesthetically favorable impression and values of public interest were able to be increased. The reasons why those hideous exposed architectural equipments were constructed, seemed to be as follows; the builders' selfishness, the citizens' ignorance and the immature social institutions that cannot restrict undesirable design efforts. Building equipments located outside are not classified as major elements in building regulations and thus can be installed and altered without any limitations even though they have great effects on the shape and colors of a building. So we have more interest in exposed architectural equipments and more deliberation of exterior design of a building.

Sjogren syndrome is a chronic systemic autoimmune disorder that chiefly involves the salivary gland and the lacrimal gland, resulting in xerostomia and xerophthalmia. Although the exact cause of the disease is not early diagnosis, treatment and observation must be emphasized because of its poor prognosis, such as the high occurrence of malignant lymphoma and other autoimmune disease that may be accompanied. In the present case, a twenty-year-old woman whose chief complaint was multiple dental hard tissue loss and xerostomia, which was misdiagnosed as iron deficiency anemia at first, but through re-evaluation and differential diagnosis it was Sjogren syndrome. the diagnosis approach was discussed in this report, suggesting that Sjogren syndrome should be considered as a differential diagnosis in a with xerostomia.

Generalized gingival enlargement, also known as gingival hyperplasia or hypertrophy, is defined as an abnormal diffuse overgrowth of gingival tissues. There are several causes of generalized gingival enlargement and they can be grouped into four categories: hereditary gingival fibromatosis, medication-induced, inflammatory, and systemic or neoplastic causes of gingival enlargement. This paper reviews the clinical features, differential diagnosis and significance of generalized gingival enlargements.

Ossifying fibromas are benign fibro-osseous tumors of mesenchymal origin. Although ossifying fibromas have principally been found in the jaw, they have also been reported in the frontal, ethmoid, sphenoid, and temporal bones, as well as the orbit and anterior cranial fossa. Ossifying fibromas affecting the jaw exhibit variable behaviors ranging from slow growth to occasionally aggressive local destruction. In the present article, we discuss a differential diagnosis considered for maxillary swellings and report a rare case of ossifying fibroma occurring in the maxilla.

This paper introduces the equivalent frequency response method (EFRM) into runoff analysis. This EFRM originally had been developed to analyze dynamic behavior of nonlinear elements such as threshold and saturation in control engineering. Many runoff models are described by nonlinear ordinary or partial differential equations. This paper presents that these nonlinear differential equations can be converted into semi-linear ones based on EFRM. The word of “a semi-linear equation” means that the coefficients of derived equations depend on average rainfall

This paper presents a lateral stability control for rear wheel drive (RWD) vehicles using electronic limited slip differentials (eLSD). The proposed eLSD controller is designed to increase the understeer characteristic by transferring torque from the outside to inside wheel. The proposed algorithm is devised to improve the lateral responses at the steady state and transient cornering. In the steady state response, the proposed algorithm can extend the region of linear cornering response and can increase the maximum limit of available lateral acceleration. In the transient response, the proposed controller can reduce the yaw rate overshoot by increasing the understeer characteristic. The proposed algorithm has been investigated via computer simulations. In the simulation results, the performance of the proposed controller is compared with uncontrolled cases. The simulation results show that the proposed algorithm can improve the vehicle lateral stability and handling performance.

Orbital floor blowout fractures can result in a variety of signs and symptoms depending on the severity of the bone defect. Large defects often result in enophthalmos and restriction of ocular movement; yet the timing of surgery can be delayed up to two weeks with good functional outcomes. In contrast, an orbital trapdoor defect with entrapment of the inferior rectus muscle usually elicits pain with marked restriction of the upward gaze and activation of the oculocardiac reflex without significant dystopia or enophthalmos. When autonomic cardiac derangement is diagnosed along with an orbital floor fracture, it has been suggested that the fracture should be treated immediately. Otherwise, it will result in continued hemodynamic instability and muscular injury and may require a second surgery. This article reports the management of an unusual presentation of a trapdoor blowout orbital floor fracture surgery with oculocardiac response in an adult, with emphasis on its pathophysiology, management, and differential diagnosis.
