In previous study about combinatorial optimization problem solver by using neural network, since Hopfield method, to converge into the optimum solution sooner and certainer is regarded as important. Namely, only static states are considered as the information. However, from a biological point of view, the dynamical system has lately attracted attention. Then we propose the "dynamical" combinatorial optimization problem solver using hysteresis neural network. In this article, the proposal system is evaluated by the N-Queen problem.

Intracranial haemorrhages are rare but potentially life-threatening complications of spine surgery. Most reported cases involved subdural or cerebellar haemorrhages; supratentorial parenchymal bleeding is very uncommon. We report a 28-year-old woman who underwent resection of a thoracic Ewing's sarcoma, and developed fatal haemorrhages around her cerebral metastases during surgery. The clinical presentations, possible pathogenesis and potential preventive measures are discussed. Patients with disseminated metastases within the neural axis are at risks of intracranial complications during spine surgery. The presence of intracranial mass lesions should be considered as a relative contraindication to intradural spine surgery.

The plume-induced shock wave is a complex phenomenon, consisting of plume-induced boundary layer separation, separated shear layer, multiple shock waves, and their interactions. The knowledge base of plume interference effect on powered missiles and flight vehicles is not yet adequate to get an overall insight of the flow physics. Computational studies are performed to better understand the flow physics of the plume-induced shock and separation particularly at high plume to exit pressure ratio. Test model configurations are a simplified missile model and two rounded and porous afterbodies to simulate moderately and highly underexpanded exhaust plumes at the transonic/supersonic speeds. The result shows that the rounded afterbody and porous wall attached at the missile base can alleviate the plume-induced shock wave phenomenon, and improve the control of the missile body.

Cartilage has a limited regenerative capacity. Faced with the clinical challenge of reconstruction of cartilage defects, the field of cartilage engineering has evolved. This article reviews current concepts and strategies in cartilage engineering with an emphasis on the application of nanotechnology in the production of biomimetic cartilage regenerative scaffolds. The structural architecture and composition of the cartilage extracellular matrix and the evolution of tissue engineering concepts and scaffold technology over the last two decades are outlined. Current advances in biomimetic techniques to produce nanoscaled fibrous scaffolds, together with innovative methods to improve scaffold biofunctionality with bioactive cues are highlighted. To date, the majority of research into cartilage regeneration has been focused on articular cartilage due to the high prevalence of large joint osteoarthritis in an increasingly aging population. Nevertheless, the principles and advances are applicable to cartilage engineering for plastic and reconstructive surgery.

Background: Cervical cancer is one of the most common female malignancies with high mortality rates in developing countries. Our purpose was to determine the prevalence of cervical cytological abnormalities by cervical cytology (CC) and the analysis of risk factors in Albanian population. Materials and Methods: A total of 5,416 conventional pap smear tests collected between January 2009 and January 2012 from Tirana University Hospital Obstetrics-Gynecology "Queen Geraldine" were retrospectively analyzed. Results: A total of 258 (4.8%) cases had epithelial abnormalities. The numbers and rates were as follows: atypical squamous cell of undetermined significance (ASCUS; n=150 [2.76%]); atypical glandular cells of undetermined significance (AGUS; n=8 [0.14%]); low-grade squamous intraepithelial lesion (LSIL; n=87 [1.6%]); high- grade squamous intraepithelial lesion (HSIL; n=10 [0.18%]); and squamous cell carcinoma (SCC; n=3 [0.05%]). Conclusions: The prevalence of cervical cytological abnormality in our study was 4.8%. A larger community-based study may establish the exact prevalence of malignant and premalignant lesions, so as to plan for future screening.

Kyung(景, 景衣), Which is Wedding ceremonial head dress, Veil. Ancient China. When dynasty is changing. wedding head dress form is different. Old china, Kyung(景) was sleeves attached dress form. But. after Dang(唐) and Song(宋) Dynasty changed square formed clothes, which is put on from head to the shoulder, and another is sleeves attached dress form. In Japan. after Edo Dynasty, Wedding veil, which was sleeves attached dress formed, head dress cloth. Mouei(帽衣). and Piuei(被衣). Ancient Korea have been face covered clothes. Myunuei(面衣). from Buyo(夫餘) to the south Silla(남국신라) Dynasty. Koryo(高麗) dynasty. likeness of the Song Dynasty square formed head wear, Mongsu(蒙首), and Kedu(蓋頭). When Chosen(朝鮮) Dynasty, Kyunguei(景衣), which was square formed 12 chuk size head wear of the blue colored veil. When King and Queen finished wedding ceremony in the another palace, Queen following the King, go to the palace. who put on the wedding veil, Kyungui(景衣), in the papanquin.
