We introduce and study the concepts of strong generalized neighborhood systems, SGNS and sg-open sets. We also introduce and investigate the concept of (${\psi},\;{\psi}^'$)-continuity and sg-continuity on SGNS's.

In this paper, we show that every unital n-Jordan homomorphism ${\varphi}$ from a Banach algebra ${\mathcal{A}}$ onto a semisimple commutative Banach algebra B is continuous.

We investigate various properties of ${\kappa}$-net convergence structures and define a ${\kappa}$-net-based continuous function on ${\kappa}$-net $\mathcal{L}^+$-convergence structures, and study relationships between continuity and ${\kappa}$-net-based continuity on ${\kappa}$-net $\mathcal{L}^+$-convergence structures. We also provide some characterizations of ${\kappa}$-net-based continuity.

The objective of this paper is to provide service continuity based on an efficient subchannel allocation in OFDMA systems. The management for handover are necessary to maintain the QoS requirements of different multimedia applications because the service continuity may be defected by some delay and information loss.

This study is aimed to assess the general population's attitude toward the continuity of medical care and its related factors. Self administered questionnaire was performed on the 1,120 office workers in the C city, Gang-won province. The questionnaire included the attitude of the continuity of medical institute, the intention of medical service use on a given case, and the variables of the related factors. 58.8% of the total respondents agreed to sustaining treatment without changing medical institutes; on the other hand, 41.2% showed negative attitude. In case that a patient would gain a recommendation of a surgery, hospitalization, or a specific examination, the total respondents' 84.9%, 61.8%, and 50.8% of each recommended situation said that they would visit another doctor and gain a diagnosis. As a result of multiple logistic analysis of determinant factor on continuity, reliability of doctors was statistically significant factor. In order to reduce wastefully used medical resources and offer well-qualified medical service, a system of second opinion among peer group or beforehand agreement could be possibly adopted. In addition, improving the image and reliability of a doctor could be an important factor to make better the behavior of medical service shopping; therefore, an effort to improve the relationship between a doctor and a patient, and restore the reliability of doctors should be paralleled.

The NGN should support an ubiquitous environment in which users can use multiple devices. Especially, services should be provided to users in a seamless manner across multiple devices which are dynamically found in users' vicinity. Therefore, supporting service continuity is essential in the NGN. Currently the IMS, which is a session control layer for the NGN, deals with session control procedures in detail for service continuity. However, the IMS provides limited methods how users can find target terminals for transferring the session. The target terminals tend to be located near in user's physical location, and could be shared among different users. For providing better service experience in the NGN, The NGN needs to encompass methods to enable for users to use the dynamically-found terminals in users' vicinity seamlessly. In this paper, we introduce a novel registration method based on virtual ISIM by which the target terminals in user's vicinity can register themselves to the IMS, and also we discuss how service continuity is supported.

Because each resource in LTE-Advanced system and network's shapes such as bandwidth, error rate change variably, it is judged that it is impossible to control service continuity with procedural, artificial, and static control method applied to the existing voice service. This research suggests a QoS management mechanism to support the service continuity effectively based on policy control. It means a method in which a subscriber's terminal collects information about its current condition and base station around, and a base station, through the data collected by monitoring inner or adjacent base station, shares related data and converges, controlling service continuity on its own.

Since the late of 20th Century, philosophy, art, and aesthetics have attention to the movement of object that persue the dynamics and qualitative change, not existing fixed and quantitative object. Qualitative continuity, including discontinuity of specific spot and surface that occurs sudden change, is distinct characteristics considered in contemporary logo civilization, which combines and disperses according as various purpose among the different elements and objects. Therefore, I studied about the characteristics of qualitative continuity that creates the change and the differentiation continuously through the "formative characteristics of the continuity expressed in contemporary fashion" of my preceding paper. This paper is the following study of above mentioned paper, and Investigates about aesthetic consciousness leading to the various change. This is intends to consider the trans-aesthetic consciousness that accepts dynamic movement and change the different object and reforms new relationship continuously. This studies' conclusion is as follows; 1) sublimity-Infinity, de-constructive, excessive 2) jouissance - functional, structural 3) paradox-perceptual, spatial. A study about the trans-aesthetic consciousness would help to offer philosophical basis, and make a change building aesthetic foundation in explaining various relationship like as phenomenon of the retro, neo, post, fusion expressed since the late of 20th Century.

The purpose of this study is to understand continuity and discontinuity of the neoclassic style in early twentieth century fashion modernism. Researching relations in fashion between eighteenth to nineteenth century and twentieth century, the theory of 'linked solution' suggested by Kubler and Broadsky has been accepted. The results of this study are as follows: In early twentieth century fashion, continuity of the neoclassic style is considered as presentation of geometric form based on anatomical truth of the human body and moderation of decoration. Also simple construction to present practical purpose of the dress in honesty were continued. On the other hand, discontinuity of the style is found in the imitation of men's classic tailored suits and standardization of sizes and styles. These are considered to reflect such early twentieth century sociocultural contexts as equality of the sexes and mechanical aesthetics. Hopefully this study will contribute to the broadening of insight in fashion connecting traditions.

This study examined risk and protective variables related with the continuity of developmental risks among 136 infants, aged 4-10 months. Using the Denver Developmental Screening Test, 136 infants among 2978 infants in the first wave of the Korea Child Panel were classified into the developmental risk group. Among the 136 risk group infants, 45 infants stayed in the risk group (continuing risk group) and the other 91 infants moved into the normal group (recovering risk group) after 1 year. Group differences were tested in the levels of infant, mother and father variables to examine which variables were associated with the continuity of developmental risks for a year. Variables indicating parents' marital relationships such as the mothers' marital satisfaction and conflict of the first wave and the fathers' marital satisfaction of the second wave significantly distinguished the continuing from the recovering risk group. In addition, there were significant group differences in the levels of mothers' self-efficacy in the first wave. The findings suggest that the exposure to marital conflict during infancy is associated with the continuity of developmental risks.
