  • Objective : The purposes of this article are to present 5 cases of intracranial meningioma with leptomeningeal dissemination (LD) and investigate the characteristics of this disease. Methods : We present a retrospective case series of 5 females at our institutions (age ranged 21-72 years, mean 54.6 years) diagnosed with LD of an intracranial meningioma after surgery between 1998 and 2013. A database search revealed 45 cases with LD of meningioma in the English literature. Characteristic features were analyzed and compared. Results : The incidence rate at our institutions of LD of meningioma was 0.9% (5/534). World Health Organization (WHO) grade was distributed as follows: I : 2, II : 2, and III : 1. Time to LD ranged from 2.5 months to 6.9 years; the patient with WHO grade III had the shortest interval to LD. The patient with an intraventricular meningioma (WHO grade II) had the second shortest interval to LD (1.7 years), and simultaneously revealed both LD and extraneuronal metastases. Four of 5 patients showed a disease progression, with the survival ranging from 1 month to 3.8 years after LD. Based on the literature, the initial tumor was an intraventricular meningioma in 9 patients, and their time to LD was shorter on average (mean 1.9 years). Histologically, 26 of 45 (58%) were initially diagnosed with a WHO grade II or III meningioma, and 6 of 19 patients (32%) with WHO grade I revealed malignant transformation. Conclusion : This study shows that intraventricular location and histologically aggressive features seem to increase the chance of LD of meningioma.

  • Purpose: The aim of the study was to evaluate the correlation of ultrasound features with breast cancer molecular status. Materials and Methods: A retrospective review was performed of ultrasound findings in 263 patients diagnosed with breast invasive ductal carcinoma for comparison with immunohistochemistric results were obtained from each lesion. Relationships between ultrasound findings and molecular status were investigated by using multiple regression analysis by means of stepwise logistic regression. Differences in ultrasound criteria were assessed among women with different molecular status. Results: ER positivity was associated with small size, lobulate, angular or spiculated margin contours, absence of calcification, posterior tumor shadowing and low elasticity score; PR positivity was associated with small size, lobulate or angular or spiculated margin contours and absence of calcification; HER2 positivity was associated with presence of calcification and absence of any echogenic halo. The calculated models of predicted molecular status were accurate and discriminating with AUCs of 0.78, 0.74, and 0.74, respectively. Conclusions: Breast cnacer ultrasound features show some correlation with the molecular status. These models may help to expand the scope of ultrasound in predicting tumor biology.

  • Technological change leads to a value shift in human society. Various cultural experiences through the digital paradigm influence the expression of fashion. This article considers fashion film as a new form for presenting fashion and explores the distinctiveness of expression in digital fashion film. For the methodology, a literature review was conducted to examine the concepts and features of digital fashion film and metareality. Empirical research was also performed by drawing from Nick Knight's digital films, "Sans Couture", "#asif", and "The Elegant Universe" and by specifically analyzing the classification of the themes, visuals, and auditory expression. The results are as follows. The proliferation of fashion film has accelerated in the internet environment. New media in the digital era allows images to become more realistic and variable through immaterial conversion. Metareality is the notion of a reality beyond existence. A metarealistic image maintains the metaphysical nature of an object and transcends empirical appearance. It possesses immaterial, transboundary, and multidimensional features, and the image is realized by digital technology. The expression analysis identifies the metareality expressed in contemporary fashion film appearing as atypical forms, irrational combinations, and the playfulness of motion. It shows a positive attitude, transcending the immaterial limit of reality toward fashion. This study indicates how fashion as products challenges the metaphysical transformation in the digital era. The exploration of metareality in digital fashion film promotes a wider perspective and understanding of the concept of fashion.

  • Born in the 19th century as an intermediate between the past and the future, steampunk provides a strong feeling of fantasy. The objective of this research is to understand the utilization of steampunk in all realms through an in-depth literature review and empirical study. Taking the findings as a foundation, we will analyze examples shown in fashion designs that are put into real production, and those designs that can provide inspiration for further design development. The research methodology will constitute a major analysis of advanced research, internet materials, and literature. Photo materials will be collected from professional websites for steampunk. The product method such as follows. Firstly, we will classify the internal meaning of characteristics in steampunk that are similar to the characteristics that are being researched, then take it as the standard and arrange to integrate all five features: restoration, pluralism, duplicity, resistibility and abnormality. We will spread out the design based on images from advanced research. Secondly, in order for to design a steampunk product, I decided on four themes: devastated environment, brutal wars, cool-headed machinery, and the overlap of the future and the past. Inspiration was acquired from representative movies and animations featuring steampunk. Thus, new directions for fashion design with steampunk features can be discovered. It raises the feasibility of this combination in modern society. In the future with the development of technology, it functions as a design that is easy for users to approach.

  • That rotavirus infection can cause neurological symptoms in young children has been well established. However, it is surprising why rotavirus infection has been overlooked as a cause of neonatal seizures for many years, despite significant research interest in neonatal rotavirus infection. Neonates are the age group most vulnerable to seizures, which are typically attributed to a wide range of causes. By contrast, because rotavirus infection is usually asymptomatic, it has been difficult to identify an association between this virus and neonatal seizures. The conventional wisdom has been that, although neonates are commonly infected with rotavirus, neurological complications are rare in this age. However, recent studies using diffusion-weighted imaging (DWI) have suggested a connection between rotavirus infection and neonatal seizures and that rotavirus infection can induce diffuse white matter injury without direct invasion of the central nervous system. The clinical features of white matter injury in rotavirus-infected neonates include the onset of seizures at days 4-6 of life in apparently healthy term infants. The recent findings seem to contradict the conventional wisdom. However, white matter injury might not be a completely new aspect of rotavirus infection in neonates, considering the forgotten clinical entity of neonatal seizures, 'fifth day fits'. With increased use of DWI in neonatal seizures, we are just starting to understand connection between viral infection and white matter injury in neonates. In this review, we discuss the historical aspects of rotavirus infection and neonatal seizures. We also present the clinical features of white matter injury in neonatal rotavirus infection.

  • Traffic congestions are rapidly increasing in urban areas. In order to reduce these problems, it needs real-time data and intelligent techniques to quickly identify traffic activities with useful information. This paper proposes a Fuzzy Domain Ontology(FDO)-based opinion mining system to monitor the transportation network in real-time as well to make a city polarity map for travelers. The proposed system retrieves tweets and reviews related to transportation activities and a city. The feature opinions are extracted from these tweets and reviews and then used FDO to identify transportation and city features polarity. This FDO and intelligent prototype are developed using $Prot{\acute{e}}g{\acute{e}}$ OWL (Web Ontology Language) and JAVA, respectively. The experimental result shows satisfactory improvement in tweets and review's analyzing and opinion mining.

  • The purpose of this paper is to review the importance of situated cognition and the features of MOO(Multi-user Object Oriented)environments for effective foreign language learning. Learning foreign languages is beyond simply recalling for the vocabularies or expression usages of targeted languages. As much the same as children naturally acquire their mother languages among active and social interactions with other surrounding people, foreign languages should be told in the circumstances and contexts for authentic applications of foreign languages. The MOO, one of the virtual realities with spatial metaphors on the text basis, has been gaining high attentions from educational fields, thanks to the strong functions of social contexts and learner interactions. This paper approaches the features of MOO as foreign language learning environments, in terms of activity, context and interaction.

  • Day care center for the elderly is an alternative for community care for frail elderly who need social participation and physical cares and services outside the family. The purpose of this study was to identify the present situation of day care center for the elderly and to suggest desirable interior space plans for elderly day care center. Data were collected by two ways; a mail survey and case studies of existing day care centers. Five cases of day care centers were analyzed to find out Physical and space problems, available programs and services. Also, the staffs in 96 day care centers for the elderly in nationwide were selected for a mail survey and 68.8 percentage of all was collected and analyzed. From the result of case studies, narrow space and lack of accessibility features for wheelchair or other prosthetic devices were the major problems. From the result of a mail survey analysis, the elderly users were over 73 years old, and high proportion had suffered from dementia and apoplexy Also, staffing ration was 1:7 In other words, one staff was caring of 7 old people, and supporting staff was insufficient. Therefore, supportive, therapeutic environment Was more important issue to improve quality of care. Separate program room and outdoor space, lounging space, treatment room by gardening, separate counselling room, bedroom, a simple kitchen unit, staff office, separate physical treatment room, resting room for staff was indicated more necessarily. When priority of planning interior space was safety followed by accessability and convenience, it was also reported that sire of each room was generally narrow. The most serious problem in interior space was the lack and narrowness of space, and accessible features for mobility. Based on the literature review and the findings of this study, two types of floor plans for elderly day care center were suggested;‘a mixed type for the elderly with and without dementia’and‘a separate type for the elderly with dementia.’The main goals for designing interior space for two types of elderly day care center were to provide safe environment, encouraging environment for remaining abilities of users, sanitary environment, therapeutic environment, familiar environment, and socially-encouraging environment. The recommendations for further studies were suggested.
