현대사회에서 건축물 외피는 단순한 물리적 기능을 넘어 많은 의미를 내포하고 있다. 그 중 외피특성에 의해 생성된 인터페이스 공간은 현대사회에서 많은 의의를 가지게 되었고, 도시의 상징적 공간으로써 역할을 수행하기도 한다. 인터페이스 공간은 두 개의 독립된 공간 사이를 연결해주고, 상태를 활성화 시키는 경계 공간이다. 인터페이스 공간에 의해 사람들은 서로 '소통'할 수 있는 기회도 많아지고, 그에 따라 공간적, 기능적으로 단절되었던 도시의 문제점도 해결 할 수 있게 되었다. 하지만 우리나라는 급격한 도시성장으로 인해 이와같은 인터페이스 공간이 잘 형성되지 못했고, 그에 따라 공간적, 시각적으로 이질성이 많이 나타나 도시 공간의 단절 문제가 야기되고 있다. 이에 본 연구에서는 부산시 중구 남포동을 대상으로 도시를 구성하고 있는 가장 큰 요소라고 할 수 있는 건축물의 외피에 의한 인터페이스 공간 특성에 관하여 연구해 보고자 한다.

As a basic study to analyze the relative importance of external space in urban development projects, this study selects evaluation indicators for external space planning and then analyzes systematic external space planning through expert surveys. The scope of the study is to examine the criteria of evaluation items for external space derived from existing studies and to suggest the importance and priority of evaluation items. As a research method, we reviewed the legal and research literature on landscape planning and external space-related guidelines, and conducted a primary review of external space planning evaluation items analyzed by questionnaire. The reviewed items were again reviewed and selected through expert group discussions (FGI). The selected evaluation items were surveyed by expert groups and analyzed in depth using the hierarchical analysis method (AHP). Looking at the relative importance of the calculated sub-items, among the 17 sub-items, 'planning open space' (.096) is the largest, followed by 'pedestrianization' (.082), 'linking with adjacent buildings, streets, parks, and green areas' (.077), 'securing public space through various planning techniques such as linking with pedestrian paths' (.066), 'Plan the placement, form, and scale of buildings in consideration of the identity of the destination' (.065), 'Plan buildings, streets, parks, and green spaces in an integrated and holistic manner' (.065), 'Harmonize with the surrounding environment (landscape)' (.063), 'Harmonize with surrounding buildings and apply landscape planning in urban planning' (.063), 'Entrances and lower floors of buildings are planned as parks for users and pedestrians' (.060), 'Preserve and expand green areas and establish maintenance plans for urban greening' (.054), 'Form the basis for a comfortable life for urban residents by providing long-term development directions' (.047), 'Activate community activities and plan pedestrian environments and streetscapes considering human scale' (.047), 'Establish and propose basic directions for urban greening' (.046), 'Plan buildings, streets, parks, and green areas considering the hierarchy and characteristics of the landscape structure' (.045), 'Plan for integrated land use' (.045), 'Create green axes in connection without cutting them due to development activities' (.044), and 'Apply barrier free design' (.034).

Let $H$ denote a separable, infinite dimensional complex Hilbert space and let $L(H)$ denote the algebra of all bounded linear operators on $H$. A dual algebra is a subalgebra of $L(H)$ that contains the identity operator $1_H$ and is closed in the $weak^*$ operator topology on $L(H)$. For $T \in L(H)$, let $A_T$ denote the smallest subalgebra of $L(H)$ that contains T and $1_H$ and is closed in the $weak^*$ operator topology.

Let X be a real Banach space with norm vertical bar . vertical bar and let I denote the identity operator. Then an operator A.contnd.X*X with domain D(A) and range R(A) is said to be accretive if vertical bar x$_{1}$-x$_{2}$ vertical bar.leq.vertical bar x$_{1}$-x$_{2}$+r(y$_{1}$-y$_{2}$) vertical bar for all y$_{i}$.mem.Ax$_{i}$, i=1, 2, and r>0. An accretive operator A.contnd.X*X is m-accretive if R(I+rA)=X for all r>0.r>0.

M. Kontsevich posed a problem on mapping class groups of 3-manifold that is if M is a compact 3-manifold with nonempty boundary, then BDiff (M rel $\partial$ M) has the homotopy type of a finite complex. Here, Diff (M rel $\partial$ M) is the group of diffeomorphisms of M which restrict to the identity on $\partial$ M, and BDiff (M rel $\partial$ M) is its classifying space. In this paper we resolve the problem affirmatively in the case when M is a Haken 3-manifold.

Choonwon, Lee Kwang-Soo was a literary man and activist for educational movement in modem age of Korea. This research was to review his arguments about improvement of house living. The major results of the research were as follows. First, he asked Korean people to establish solid identity of living. Second, he placed great emphasis on building hygiene facilities and bathroom. Third, he argued that the space within a household need to be divided in accordance with function. Finally he suggested Korean people to make home environment beautiful and convenient.

Along with the recent pressures for market liberalizations in the legal services sector, the topsizing, multinationalization, and specialization of Law Firms have brought about the need for them to view the profession itself from a marketing perspective and promote corporate identity to improve productivity and garner clientele. With this in mind, this study attempts the revamping of the traditionally, conservative and cramped characteris-tics of Law Firms' interior space into more open and dy-namic ones with a contemporary and international feel which are also superior from a marketing viewpoint.

Let $H$ be a separable, infinite dimensional, complex Hilbert space and let $L(H)$ be the algebra of all bounded linear operaors on $H$. A dual algebra is a subalgebra of $L(H)$ that contains the identity operator $I_H$ and is closed in the $weak^*$ topology on $L(H)$. Note that the ultraweak operator topology coincides with the $weak^*$ topology on $L(H)$ (see [5]).

인터넷의 확산과 웹 2.0 환경의 도래에 따라, 사용자가 관리해야 하는 디지털 형태의ID 정보가 기하 급수적으로 증가하고 있다. 이것은 사용자의 ID 관리 부담, 동일한 패스워드의 반복적인 사용으로 인한 보안성 저하, ID 정보의 유출에 의한 사용자 프라이버시 침해 문제 등을 발생시키고 있다. 따라서 사용자를 인증하고, 사용자의 ID 정보를 관리해주는 ID 관리 시스템이 매우 중요해지고 있다. 본 고에서는 인터넷 규모의 온라인 서비스를 대상으로 사용자를 인증하고 사용자의 ID 정보를 관리하는 대표적인 ID관리 시스템인 SAML, CardSpace, Open ID를 살펴 보고, 이들 시스템의 특징을 비교 분석한다.

In this paper we show that if there is a derivation on a commutative Banach algebra which has a non-nilpotent separating space, then there is a discontinuous derivation on a commutative Banach algebra which has a range in its radical. Also we show that if every prime ideal is closed in a commutative Banach algebra with identity then every derivation on it has a range in its radical.
