Enterprise Architecture (EA) is one of controversial subjects theses days. Some organizations, public or private, are very impetuous in adopting it and some are quite Indifferent to it. What makes this difference come about? This is our research question. One previous research has studied on this issue under the theory of diffusion of innovation. Instead, we here attempt to investigate, in the context of technology transfer theory, the influencing factors on the adoption of EA. We are especially interested In whether korea local organizations are more Influenced by 'need pull' factors than 'institutional push' factors or vice versa.

근대이전 동아시아의 상류사회는 시서화 삼위일체의 통합체제를 유지해왔고 이에 따라 정원조성의 원리 또한 산수화의 작화원리를 참조하며 발전해 왔다. 본 연구는 중국의 산수화론과 원림론을 비교, 양자 간의 상호관계를 검토함으로써 동양그림의 경관관이 원림의 작정원리에 미친 영향을 고찰하고자 하였다. 양자 간의 비교는 내용과 형식의 양 측면에서 이루어졌다. 여기서 내용은 주로 가치와 의미 등 비가시적 측면을 말하고, 형식은 주로 시각과 공간 등 가시적 측면을 말한다. 먼저 산수화론에 있어 내용면의 주요 주제는 무엇보다도 '기운생동(氣韻生動)'이었다. 이는 음양사상을 기반으로한 동양문화 고유의 가치인데, 남조의 사혁이 이론화한 것이다. 이에 대응하는 원림론의 주요 주제는 '풍수(風水)'와 '의경(意境)'이었다. 풍수 역시 음양사상을 기반으로 한 지기(地氣)의 원리이고, '의경'이란 시서화 공동의 가치로서 마음의 경지를 의미하는데, 특히 원림론에서는 가시적 경관 이면의 상징적 의미를 말하고 있다. 형식면에서 산수화론의 두드러진 주제는 북송조 곽희에 의해 정립된 '삼원법(三遠法)'이라는 일종의 동양화의 투시도법으로 다원적 조망을 특징으로 한다. 이에 대응하는 원림론의 주제는 '인지(因地)'와 '차경(借景)'으로 명조의 계성이 이론화하였으며, 각각 대상지 내외부 경관자원의 조성과 차용을 의미한다. 특히 차경의 세목들은 삼원법의 각 관점에 대응하고 있다. 결론적으로 동아시아 원림론에 등장하는 주요 개념들은 화론과 매우 긴밀하게 연관되어 있었으며 이로서 원림술은 예술의 한 분야로 인정받아 왔다.

Pungsu acts as a strong guideline for selecting a location of the village having a certain geographical condition. The attitude of choosing an auspicious site regarding the shape of mountains and water stream, is widely accepted by the intelligent class of Josen period. Therefore, the theory is one of the main factor influenced on the traditional village and house in Korea. Regarding the fact that a real effect of pungsu on the formation of traditional village and house, Study with a view of Pungsu theory could be a good method for deeply understanding the traditional architecture in Korea. In this context, the study analyzes the site and space lay out of an upper class house of vice minister Lee(Lee, Jung Ryul, 1868~1950) in Oeam historic village with Pungsu theory. The house is composed of Anchae(house for the women) and Sanrangchae(house for the men and receiving guests) and Hangrangchae(servants' quarters). Through the study, It finds out that the house is carefully selected and planned considering surrounding physical environment so called Jusan(back hill), Ansan(front hill), Choengyong(blue dragon) and Beckho(white tiger) of Pungsu theory.

Springing is the resonance phenomenon of a ship hull girder with incoming waves having the same natural frequency of the ship. In this study, a simple and reliable calculation method was developed based on quadratic strip theory using the Timoshenko beam approach as an elastic hull girder. Second-order hydrodynamic forces and Froude-Krylov forces were applied as the external force. To improve the accuracy of the strip method, the variation in the added mass along the ship hull longitudinal direction, so called tip-effect, was considered. The J-factor was also employed to compensate for the effect of three-dimensional fluid motion on the two-node vibration of the ship. Using the developed method, the first- and second-order vertical bending moments of the Flokstra ship were compared. A comparative study was also carried out for a uniform barge ship and a 10,000 TEU container ship with the respective methods including the J-factor and tip-effect.

This paper presents prediction of ultimate longitudinal strength of a VLCC, "Energy Concentration" for which many benchmark studies have been carried out, based on kinematic displacement method proposed by Tayyar and Bayraktarkatal (2012). Kinematic displacement theory provides semi-analytical solution of average compressive strengths for various kinds of stiffened panels. The accuracy of average compressive strengths obtained from formulas of CSR(common structural rules) for tankers and kinematic displacement method are discussed in the fore part of this paper. Hull girder ultimate strengths using Smith method are also compared for different average compressive strengths. By comparing them with other benchmark results, it is concluded that the new method provides lower bounds, because hull girder strengths under the sagging and hogging moment conditions approach nearly lower bounds.

The purpose of this study is to overview domestic and foreign trends in the study of the landscape evaluation through new framework of landscape evaluation studies. 108 studies on the landscape evaluation are summarized and categorized into theoretical studies, verification of theories, development of evaluation methods and applications in physical planning. Major theories in the landscape evaluation came from the psycho-physics, the evolutionary theory ann the cultural-learning theory, and were verified and applied into physical planning. Early experimental researches on landscape evaluation, based on psycho-physics, were focused on relatively simple responses to landscapes. But many studies have been gradually related to the evolutionary theory and the cultural learning theory, emphasizing biological and cultural effects on landscape evaluation. Especially, Appleton's Prospect-Refuge theory' and Kaplans' 'Information Processing model' have very strong influence in landscape evaluation. Relatively there have been many application researches in Korea, which tells there have been strong needs to solve pending practical problems caused by the rapid economic and social growth for several decades. Almost of applications in physical planning are focused on physical features of landscapes, but for more comprehensive landscape evaluation, many other factors such as cognitive and sociocultural variables should be integrated into the whole evaluation system. As a result of reviewing of landscape evaluation studies, I found the overall domestic and foreign trends and the necessity of more research on the applications in physical planning. Because this study mainly focused on academic researches, for more appropriate landscape evaluation and management there should be more practical researches including various approaches.

An outline of the Timoshenko beam theory is presented. Two differential equations of motion in terms of deflection and rotation are comprised into single equation with deflection and analytical solutions of natural vibrations for different boundary conditions are given. Double frequency phenomenon for simply supported beam is investigated. The Timoshenko beam theory is modified by decomposition of total deflection into pure bending deflection and shear deflection, and total rotation into bending rotation and axial shear angle. The governing equations are condensed into two independent equations of motion, one for flexural and another for axial shear vibrations. Flexural vibrations of a simply supported, clamped and free beam are analysed by both theories and the same natural frequencies are obtained. That fact is proved in an analytical way. Axial shear vibrations are analogous to stretching vibrations on an axial elastic support, resulting in an additional response spectrum, as a novelty. Relationship between parameters in beam response functions of all type of vibrations is analysed.

A new procedure for determining properties of thick plate finite elements, based on the modified Mindlin theory for moderately thick plate, is presented. Bending deflection is used as a potential function for the definition of total (bending and shear) deflection and angles of cross-section rotations. As a result of the introduced interdependence among displacements, the shear locking problem, present and solved in known finite element formulations, is avoided. Natural vibration analysis of rectangular plate, utilizing the proposed four-node quadrilateral finite element, shows higher accuracy than the sophisticated finite elements incorporated in some commercial software. In addition, the relation between thick and thin finite element properties is established, and compared with those in relevant literature.

The theory of Place is based on the relations of human being, environment and architecture in the view of the existentialism and phenomenology. A place has two respects, the one is Natural place as landscape and the other is Man-made place as city, public building , private house. These properties of place are appeared through axis , directions, boundaries, centers , enclosures that are basic elements in architecture . Therefore these elements embody sense of place as orientation , identification , identity. imageability, stabilitas loci, heirarchy. And these sensually compositional elements of poace concretize district, landmark, node, path, edge that ceate a setting into work and place in architecture & interior design.
